                              PROSPECTUS SUMMARY

   This summary highlights information contained elsewhere in this prospectus
or incorporated by reference into this prospectus. This summary does not
contain all the information that is important to you. We encourage you to read
this entire prospectus including the "Risk Factors" section, and the documents
we incorporate by reference carefully. All references to "Company," "we" or
"our" in this prospectus refer to Amtran, Inc. and its subsidiaries
collectively, unless the context otherwise requires.

                                  The Company

   Amtran owns American Trans Air, Inc. ("ATA"), the eleventh largest
passenger airline in the U.S. (based on 1998 revenues) and a leading provider
of airline services in selected market segments. We are also the largest
commercial charter airline in the U.S. and the largest charter provider of
passenger airline services to the U.S. military, in each case based on
revenues. For the nine months ended September 30, 1999 our revenues consisted
of 55.6% scheduled service, 24.4% commercial charter service and 10.6%
military charter service, with the balance derived from related travel
services.

Scheduled Service

   We provide scheduled service through ATA to selected destinations primarily
from gateways at Chicago-Midway and Indianapolis, and we also provide
transpacific services between the western U.S. and Hawaii. In the second and
third quarters of 1998, we added scheduled service between Chicago-Midway and
the Dallas-Ft. Worth, Denver, New York-LaGuardia and San Juan. We focus on
routes where we believe we can be a leading provider of non-stop jet service
and target leisure and value-oriented business travelers.

Commercial Charter Service

   We are the largest commercial charter airline in the U.S. and provide
services throughout the world, primarily to U.S. and European tour operators.
We seek to maximize the profitability of these operations by leveraging our
leading market position, diverse aircraft fleet and worldwide operating
capability. Our management believes our commercial charter services are a
predictable source of revenues and operating profits. In part, this is because
our commercial charter contracts require tour operators to assume capacity,
yield and fuel price risk, and also because of our ability to re-deploy assets
into favorable markets. Our commercial charter services are marketed and
distributed through a network of domestic and international sales offices.

Military/Government Charter Service

   We have provided passenger airline services to the U.S. military since 1983
and are currently the largest charter provider of these services. Our
management believes that because these operations are generally less seasonal
than leisure travel, they have tended to have a stabilizing impact on our
operating margins. The U.S. government awards one year contracts for its
military charter business and pre-negotiates contract prices for each type of
aircraft that a carrier makes available. We believe that our fleet of aircraft
is well suited to the needs of the military for long-range service.

                    SUMMARY OF TERMS OF THE EXCHANGE OFFER

   In the exchange offer we will accept for exchange up to $75,000,000
aggregate principal amount of Outstanding Notes for an equal aggregate
principal amount of Exchange Notes. The Exchange Notes are our obligations
entitled to the benefits of the Indenture, as supplemented, relating to the
Outstanding Notes. The form and terms of the Exchange Notes are the same as
the form of the Outstanding Notes except that the Exchange Notes have been
registered under the Securities Act.

Background................... On December 21, 1999, we completed a
                              private placement of $75,000,000 aggregate
                              principal amount of our 10 1/2% Senior Notes
                              under an Indenture dated July 24, 1997 as
                              supplemented by the First Supplemental
                              Indenture, dated December 21, 1999. In
                              connection with that private placement, we
                              entered into a registration rights agreement in
                              which we agreed, among other things, to deliver
                              this prospectus to you and to complete an
                              exchange offer.

Securities Offered........  Up to $75,000,000 aggregate principal amount of
                             10 1/2% Senior Exchange Notes due August 1, 2004,
                             which have been registered under the Securities
                             Act. The terms of the Exchange Notes are
                             substantially the same as the terms of the
                             Outstanding Notes except for certain transfer
                             restrictions and registration rights relating to
                             the Outstanding Notes and except that, if the
                             exchange offer is not consummated on or prior to
                             [May 19, 2000], the interest rate borne by the
                             Outstanding Notes will increase by a certain
                             amount until the exchange offer is consummated.
                             See "Description of the Notes--Registration
                             Rights for Outstanding Notes."

                             We currently have outstanding $100,000,000
                             aggregate principal amount of Exchange Notes that
                             we issued in 1997. The Exchange Notes offered by
                             this prospectus are part of the same series of
                             Exchange Notes that we issued in 1997.

The Exchange Offer........   We are offering to accept for exchange your
                             unregistered, old Outstanding Notes for our new
                             Exchange Notes that have been registered under
                             the Securities Act of 1933. As of the date
                             hereof, $75,000,000 in aggregate principal amount
                             of Outstanding Notes are outstanding. On or

Consequences If You Do
Not Exchange Your            Outstanding Notes that are not tendered in the
Outstanding Notes.........   exchange offer or are not accepted for exchange
                             will continue to accrue interest, but will not
                             retain any rights under the registration rights
                             agreement and will bear legends restricting their
                             transfer. You will not be able to offer or sell the
                             Outstanding Notes unless:

                             o pursuant to an exemption from the requirements
                               of the Securities Act of 1933;

                             o the old notes are registered under the
                               Securities Act of 1933; or

                             o the transaction requires neither such an
                               exemption nor registration.

                             We do not currently anticipate that we will
                             register Outstanding Notes under the Securities
                             Act. See "Risk Factors--Consequences of Failure to

                   Summary Description of the Exchange Notes

          The terms of the Exchange Notes are identical in all material
respects to the terms of the Outstanding Notes, except for certain transfer
restrictions and registration rights relating to the Outstanding Notes and
except that, if an exchange offer with respect to the Exchange Notes is not
consummated by May 19, 2000, 150 days after the Closing Date of the
December 21, 1999 private placement, the rate per annum at which the
Outstanding Notes bear interest will be increased temporarily. See
"Registration Rights for Outstanding Notes."

          Holders of Outstanding Notes whose Outstanding Notes are accepted
for exchange will not receive any payment of interest on the Outstanding
Notes to be exchanged instead. Holders will receive a full semi-annual
interest payment on August 1, 2000, which is the next regularly scheduled
interest payment date on the Exchange Notes.

Securities Offered........   Up to $75,000,000 aggregate principal amount of 10
                             1/2% Senior Exchange Notes due August 1, 2004,
                             which have been registered under the Securities
                             Act, issued by the Company.

Interest..................   Interest on the Notes is payable semiannually in
                             cash on February 1 and August 1.

Optional Redemption          On or after August 1, 2002, we may redeem some or
by the Company............   all of the Notes at the redemption prices listed
                             in the section entitled "Description of the
                             Notes--Optional Redemption." Prior to such date,
                             we may not redeem the Notes, except as described
                             in the following paragraph.

                             At any time prior to August 1, 2002, we may redeem
                             up to 35% of the aggregate principal amount of
                             the Notes with the proceeds of certain sales of
                             common stock at a redemption price equal to
                             110.50% of the principal amount thereof, plus
                             accrued interest, so long as at least 65% of the
                             aggregate amount of the Notes remains
                             outstanding after each such redemption.

Ranking...................   The Exchange Notes will be unsecured and:

                             o will rank equally with all of our unsecured,
                               unsubordinated indebtedness existing or created
                               in the future; and

                             o will be effectively subordinated to all of our
                               obligations under secured indebtedness to the
                               extent of such security and will be senior to
                               all of our subordinated indebtedness created in
                               the future.

                              At September 30, 1999, on a pro forma basis after
                              giving effect to the December 21, 1999 private
                              placement, on a consolidated basis, we would
                              have had outstanding approximately $359.4
                              million of indebtedness, approximately $55.0
                              million of which would have been secured. See
                              "Description of the Notes--Ranking."

Guarantee.................    All payments with respect to the Notes (including
                              principal and interest) are unconditionally
                              guaranteed on an unsecured unsubordinated basis,
                              jointly and severally, by each of the following
                              subsidiaries (the Guarantors):

                              o American Trans Air, Inc.;

                                Inc.);

                              o Amber Travel, Inc.;

                              o Chicago Express Airlines, Inc.

                              Such guarantees:

                              o will rank equally with all existing and future
                                unsecured unsubordinated indebtedness of the
                                Guarantors;

                              o will be effectively subordinated to secured
                                indebtedness of the Guarantors to the extent of
                                such security; and

                              o will be senior in right of payment to all future
                                subordinated indebtedness of the Guarantors.

                              At September 30, 1999, on a pro forma basis after
                              giving effect to the December 21, 1999 private
                              placement, the Guarantors (on a consolidated
                              basis excluding indebtedness owed to us and our
                              indebtedness) would have had approximately
                              $359.4 million of indebtedness outstanding
                              (other than the Guarantees), $55.0 million of
                              which would have been secured indebtedness.

                              subject to certain conditions, to require us to
                              purchase your Notes at a purchase price equal to
                              101% of the principal amount plus accrued and
                              unpaid interest, if any, to the date of purchase.
                              There can be no assurance that we will have the
                              financial resources necessary to purchase the
                              Notes upon a change of control. See "Description
                              of the Notes--Repurchase of Notes upon a Change

                              registration statement. If such exchange offer
                              is not filed, has not been declared effective,
                              or is not consummated or such shelf registration
                              statement is not filed or declared effective
                              within the time periods specified in

                              interest on the Outstanding Notes until such
                              exchange offer is entered into or such shelf
                              registration statement is declared effective. If
                              you choose not to participate in the exchange
                              offer or shelf registration, you may thereafter
                              hold a less liquid security. See "Risk
                              Factors--Lack of Public Market for the Notes"
                              and "Description of the Notes--Registration

                                USE OF PROCEEDS

          We will receive no cash proceeds from the exchange offer.

          The exchange offer is intended to satisfy certain of our obligations
under the registration rights agreement. Your Outstanding Notes tendered in
exchange for Exchange Notes will be retired and canceled and cannot be
reissued. Accordingly, the issuance of the Exchange Notes will not result in
any increase or decrease in the indebtedness of the Company.

          The net proceeds from the December 21, 1999 private placement were
approximately $73.0 million. These proceeds were used by the Company for
general corporate purposes, including to fund working capital requirements and
fleet acquisitions and improvements.

                                 RISK FACTORS

          For a description of certain factors that should be considered by
Holders who tender their Outstanding Notes in the exchange offer, see "Risk
Factors" beginning on page 12.

                                 RISK FACTORS

          You should carefully consider the risks described below, as well as
other information included in this prospectus, when evaluating your
participation in the exchange offer. This list may not be exhaustive, and
these or other factors could adversely impact our ability to service our
indebtedness.

Risk Factors Relating to Amtran

          Our high proportion of debt compared to our equity capital may
impair our flexibility.

          We have a higher proportion of debt compared to our equity capital
than some of our principal competitors. We need substantial cash resources to
meet scheduled debt and lease payments and to finance day-to-day operations.
As a result, we may be less able than some of our competitors to withstand a
prolonged recession in the airline industry or respond to changing economic
and competitive conditions. We may be restricted in our ability to exploit new
business opportunities. In addition, our ability to obtain additional
financing in the future for working capital, capital expenditures,
acquisitions or other purposes may be impaired.

          As of September 30, 1999, on a pro forma consolidated basis after
giving effect to the private placement, we had:

          o    $182.0 million of cash, cash equivalents and short-term
               investments;

          o    $359.4 million of indebtedness outstanding (approximately $55.0
               million of which was secured); and

          o    $148.8 million of shareholders' equity.

As a result, at that date, total consolidated debt was 70.7% of total
capitalization, which represents significant financial leverage, even in
the highly leveraged airline industry. In addition, ATA has substantial
obligations under operating leases for 25 aircraft, which are not recorded
as indebtedness and expects to lease additional aircraft in the future.

          On a pro forma basis, after giving effect to the Original Offering
as if it had occurred at the beginning of the period, we would have had
interest expense of approximately:

          o    $20.7 million for the year ended December 31, 1998; and

          o    $21.3 million for the nine months ended September 30, 1999.
               This would have resulted in an EBITDA to interest expense ratio
               of approximately:

          o    7.9 times for the year ended December 31, 1998; and

          o    7.9 times for the nine months ended September 30, 1999.
               Similarly, the ratio of EBITDAR to the sum of interest (net of
               capitalized interest) plus aircraft rentals would have been:

          o    2.9 for the year ended December 31, 1998; and

          o    3.3 for the nine months ended September 30, 1999.

Our ability to satisfy our obligations will be dependent upon our future
performance, which is subject to general economic conditions and to
financial, business and other factors, including factors beyond our
control. Our operating results and cash flow could be adversely affected by
such factors as price competition, increases in fuel costs, a downturn in
general economic conditions and adverse regulatory changes.

          The degree to which we are leveraged could have important
consequences to you, including the following:

          (i) our ability to obtain additional financing in the future for
     working capital, capital expenditures, acquisitions or other purposes may
     be impaired;


                                      11


<PAGE>




          (ii) our degree of leverage and related debt service obligations, as
     well as our obligations under operating leases for aircraft, may make us
     more vulnerable than some of our competitors in a prolonged economic
     downturn; and

          (iii) our financial position may restrict our ability to exploit new
     business opportunities and limit our flexibility to respond to changing
     business conditions. Our competitive positions may also be affected by
     the fact that we may be more highly leveraged than some of our
     competitors.

        We generally operate with a working capital deficit and we may
          require additional financing to meet our obligations.

          Although we, like most other airlines, generally operate with a
working capital deficit, we have met our obligations as they have become due.
In order to meet short-term cash needs, ATA maintains bank credit facilities.
At September 30, 1999, our current assets were $208.3 million, and our current
liabilities were $232.9 million.

          In addition, we require significant levels of capital investment for
aircraft, engine and airframe maintenance and acquisition to maintain our
competitive position and to expand our operations. For the year ended December
31, 1999, we expect that:

          o    capital expenditures for scheduled maintenance will total
               approximately $110.4 million;

          o    capital expenditures for acquisitions of additional aircraft
               and renovations of both the Chicago-Midway terminal and hanger
               and the Indianapolis maintenance and operations center will
               total approximately $154.4 million; and

          o    additional capital expenditures will total approximately $11.5
               million.

          We also generally expect to refinance our long-term debt at or prior
to its maturity.

          We may seek to supplement our current sources of financing with
other sources of long-term financing, including obtaining vendor financing,
entering into sale-leaseback transactions and making public and private debt
offerings. We may also seek additional equity financing. We cannot assure you
that any such financing would be available on satisfactory terms.

                       Our earnings have been volatile.

          For the year ended December 31,1996, we incurred a net loss of $26.7
million. For the years ended December 31, 1997 and 1998, we had net income of
$1.6 million and $40.1 million, respectively. For the nine months ended
September 30, 1999, we had net income of $46.9 million. Although we recorded
net income in 1997 and 1998 and for the nine months ended September 30, 1999,
we cannot assure you that this profitability will continue in future years.
Moreover, because of the cyclicality of the airline industry, our results of
operations may continue to be volatile.

          Among other things, our earnings are significantly affected by
changes in fuel costs. These costs have been escalating during the first nine
months of 1999. See "Risk Factors Relating to the Airline
Industry--Significant additional increases in the cost of aircraft fuel could
adversely impact our operating results."

        We may pursue strategic alternatives that result in a change of
               control, and we may not be able to satisfy all of
          our obligations upon the occurrence of a chance of control.

          We have previously considered possible business combinations with
air carriers and others, and it is possible that in the future we will
enter into a transaction that will result in a change of control of Amtran.
All borrowings outstanding under the bank credit facilities maintained by
ATA, which are guaranteed by Amtran, and all amounts due under the Exchange
10 1/2% senior notes due 2004 and the 9 5/8% senior notes due 2005 issued
by Amtran may be accelerated upon a change of control of Amtran. See
"--Risk Factors Relating to the Notes--Payment Upon a Change of Control."
We cannot assure you that we would be able to satisfy all of our
obligations under the bank credit facilities and the Exchange Notes upon
acceleration. The failure to satisfy our obligations would materially
adversely affect our business, operations and financial results.


                                      12

        Our existing financing agreements and operating leases contain
             restrictive covenants that may limit our flexibility.

          Our existing debt financing agreements and our operating leases
relating to some of our aircraft contain restrictive covenants that impose
significant operating and financial restrictions on us. For example, the bank
credit facilities maintained by ATA and the indenture relating to the Exchange
Notes prohibit or restrict our ability to:

          o    incur additional indebtedness;

          o    create material liens on our assets;

          o    sell assets or engage in mergers or consolidations;

          o    redeem or repurchase outstanding debt;

          o    make specified investments;

          o    pay cash dividends; and

          o    engage in other significant transactions.

The indenture relating to our 9 5/8% senior notes due 2005 contains similar
restrictions. In addition, our financing agreements and our operating
leases require us to maintain compliance with specified financial ratios
and other financial and operating tests.

          These restrictions and requirements may limit our financial and
operating flexibility. In addition, if we fail to comply with these
restrictions or to satisfy these requirements, our obligations under our debt
and operating leases may be accelerated. We cannot assure you that we would be
able to satisfy all of these obligations upon acceleration. The failure to
satisfy these obligations would materially adversely affect our business,
operations and financial results.

Compliance with Department of Transportation regulations could reduce our
liquidity.

          Under current Department of Transportation regulations regarding
charter transportation originating in the U.S., all charter airline tickets
must generally be paid for in cash and all funds received from the sale of
charter seats and, in some cases, the costs of land arrangements, must be put
in escrow by the tour operator or protected by a surety bond satisfying
certain prescribed standards. Currently, we provide a third-party bond that is
unlimited in amount to satisfy our obligations under these regulations. Under
the terms of our bonding arrangements, the issuer of the bond has the right to
terminate the bond at any time on 30 days' notice. We provide a $1.5 million
letter of credit to secure our potential obligations to the issuer of the
bond. If the bond were to be materially limited or canceled, we, like all
other U.S. charter airlines, would be required to escrow funds to comply with
the Department of Transportation regulations. Compliance with these
regulations would reduce our liquidity and require us to fund higher levels of
working capital range up to $16.9 million based on 1998's peak pre-paid
bookings and up to $32.0 million based on peak pre-paid bookings for the first
nine months of 1999.

     We may incur substantial losses in the event of an aircraft accident.

          We may incur substantial losses in the event of an aircraft
accident. These losses may include the repair or replacement of a damaged
aircraft, and the consequent temporary or permanent loss of the aircraft from
service, as well as claims of injured passengers and other persons.

          We are required by the Department of Transportation to carry
liability insurance on each of our aircraft. We maintain public liability
insurance in the amount of $1.5 billion. Although we believe our insurance
coverage is adequate, we cannot assure you that the amount of our insurance
coverage will not be changed or that we will not be forced to bear substantial
losses from accidents. Substantial claims resulting from an accident could
have a material adverse effect on our business, operations and financial
results and could seriously inhibit passenger acceptance of our services.

Customers

        Our customers may cancel or default on their contracts with us.

          Customers who have contracted with us may cancel or default on their
contracts, and we may not be able to obtain other business to cover the
resulting loss in revenues. If customers with large contracts cancel or
default and we are not able to obtain other businesses, our financial position
could be materially adversely impacted.

          Our largest customer during each of the last three years was the
U.S. military, which accounted for 11.2% of our total operating revenues in
1996, 16.8% of our total operating revenues in 1997 and 13.3% of our total
operating revenues in 1998. We expect that during 1999 the U.S. military will
continue to be our largest customer and will account for approximately 11.4%
of operating revenues.

          In 1998, our five largest non-military customers accounted for
approximately 14.4% of total operating revenues, and our ten largest
non-military customers accounted for approximately 17.5% of total operating
revenues. No single non-military customer accounted for more than 10% of total
operating revenues during this period.

Effects of Seasonality of Business on the Company

          Our airline business is significantly affected by seasonal
        factors, and our results of operations for any one quarter are
        not necessarily indicative of our annual results of operations.

          Our airline businesses are significantly affected by seasonal
factors. Historically, we have experienced reduced demand during the fourth
quarter as demand for leisure airline services during this period is lower
relative to other times of the year. Our results of operations for any one
quarter are not necessarily indicative of our annual results of operations.

          In 1998 and 1999, our results for the first three quarters were
significantly stronger than we have experienced in any comparable first three
quarters of any prior year. Also in 1998, we experienced our first profitable
fourth quarter since becoming a public company in 1993. We cannot assure you
that the level of profitability achieved in 1998 and for the nine months ended
September 30, l999 will be maintained in subsequent years.

Employee Relations

            Many of our employees are represented by unions, and a
                  prolonged dispute with our employees could
                  have an adverse impact on our operations.

          Our flight attendants are represented by the Association of Flight
Attendants and our cockpit crews are represented by the Air Line Pilots
Association. A prolonged dispute with our employees who are represented by
either of these unions, or any sizable number of our employees, could have an
adverse impact on our operations.

          Our current collective bargaining agreement with the Association of
Flight Attendants became subject to amendment, but did not expire, in December
1998. Our current collective bargaining agreement with the Air Line Pilots
Association will be subject to amendment, but will not expire, in September
2000. We commenced negotiations with the Association of Flight Attendants in
the third quarter of 1998 to amend our existing collective bargaining
agreement, but we cannot assure you that there will not be work stoppages or
other disruptions.

          Our flight dispatchers elected the Transport Workers Union to
represent them in October 1999. Due to the small number of our dispatchers,
the election is expected to have a minimal impact on our operations.

Reliance on Travel Agents and Tour Operators for Ticket Sales

       Our revenues could be adversely impacted by our relationship with
                      travel agents and tour operators.

          Our revenues could be adversely impacted if travel agents and tour
operators elect to favor other airlines or to disfavor us. Our relationship
with travel agents and tour operators may be affected by:

          o    the size of override commissions offered by other airlines;

          o    changes in our arrangements with other distributors of airline
               tickets; and

          o    the introduction of new methods of selling tickets.

          In 1998, approximately 68% of our revenues were derived from tickets
sold by travel agents or tour operators, and, in 1997, approximately 71% of
our revenues were derived from tickets sold by travel agents or tour
operators. Although we will continue to strive to offer competitive products
to travel agencies and tour operators, we cannot assure you that we will be
able to maintain favorable relationships with these ticket sellers.

Risk Factors Relating to the Airline Industry

          Because the airline industry is characterized by low gross
            profit margins and high fixed costs, a minor shortfall
      from expected revenue could have a significant impact on earnings.

          The airline industry as a whole and scheduled service in particular
are characterized by low gross profit margins and high fixed costs. The costs
of operating each flight do not vary significantly with the number of
passengers carried and, therefore, a relatively small change in the number of
passengers or in fare pricing or traffic mix could, in the aggregate, have a
significant effect on operating and financial results. Accordingly, a minor
shortfall from expected revenue levels could have a significant impact on
earnings.

        Our products and services face varying degrees of competition.

          Competition for Scheduled Services. In scheduled service, we compete
against both the large U.S. scheduled service airlines and, from time to time,
against smaller regional or start-up airlines. Competition is generally based
on price, schedule, quality of service and convenience. All of the major U.S.
scheduled airlines are larger than we are, and most of them have greater
financial resources than we do. Where we seek to expand our service by adding
routes or frequency, competing airlines may respond with intense price
competition. In addition, when other airlines seek to establish a presence
over new routes, they may engage in significant price discounting. Because of
our size and financial resources relative to the major airlines, we are less
able to absorb losses from these activities than many of our competitors.

          Competition for Commercial Charter Services. In commercial charger
service, we compete against both the major U.S. scheduled airlines and smaller
U.S. charter airlines, including Sun Country and Miami Air. We also compete
against several European and Mexican charter and scheduled airlines, some of
which are larger than we are and have substantially greater financial
resources than we do.

          The scheduled carriers compete for leisure travel customers with our
commercial charter operations in a variety of ways, including by:

          o    wholesaling discounted seats on scheduled flights to tour
               operators;

          o    promoting packaged tours to travel agents for sale to retail
               customers; and

          o    selling discounted, excursion airfare-only products to the
               public.

As a result, all charter airlines, including ATA, generally compete for
customers against the lowest revenue-generating seats of the scheduled
airlines. During periods of dramatic rate cuts by other scheduled airlines,
we are forced to respond competitively to these deeply discounted prices.

          We also compete directly against other charter airlines. In the
U.S., these charter airlines are smaller in size than we are. In Europe,
several charter airlines are as large or larger than we are. As a result, in


                                      15


<PAGE>



addition to their greater access to financial resources, these charter
airlines may have greater distribution capabilities, including, in some cases,
exclusive or preferential relationships with affiliated tour operators.

          Competition for Military and other Government Charter Services. We
generally compete for military and other government charters with primarily
smaller U.S. airlines. The allocation of U.S. military air transportation
contracts is based upon the number and type of aircraft a carrier, alone or
through a teaming arrangement, makes available for use to the military. The
formation of competing teaming arrangements that have larger partners than
those in which we participate, an increase by other air carriers in their
commitment of aircraft to the military or the withdrawal of our current
partners or a change in the manner of awarding future contracts could
adversely affect our U.S. military charter business.

                Significant additional increases in the cost of
          aircraft fuel could adversely impact our operating results.

          Fuel costs are a significant portion of our operating costs,
comprising approximately 16.3% of our operating costs in 1998 and
approximately 15.9% of our operating costs in the first nine months of 1999.
In the first nine months of 1999 our monthly average fuel cost has risen
approximately 45.2% and over the subsequent two months, fuel costs have risen
an additional 5.3%. If fuel prices continue to rise significantly, we would
expect to suffer a significant adverse impact on our operating results,
particularly for our scheduled service and our charter contracts that do not
contain fuel cost escalation provisions. In addition, substantial increases in
fuel costs and any resulting increase in air fares would likely cause a
reduction in leisure travel or the cancelation or renegotiation of previously
booked commitments from tour operators.

          Fuel prices are affected by, among other factors, political and
economic influences that we cannot control. In the event of a fuel supply
shortage resulting from a disruption of oil imports or other events, higher
fuel prices or the curtailment of scheduled service could result.

          We have worked to reduce some of the risks associated with a rise in
fuel costs. In 1998, approximately 45.0% of our total operating revenues were
derived from contracts that enable us to pass through increases in fuel costs,
including contracts with the U.S. military, and, in the first nine months of
1999, approximately 36.0% of our total operating revenues were derived from
these types of contracts. We are, however, exposed to increases in fuel costs
that occur with 14 days of flight time, to most increases associated with our
scheduled service and to increases affecting contracts that do not include
fuel cost escalation provisions.

  The profitability of our operations is influenced by economic conditions
      as demand for leisure travel diminishes during economic downturns.

          The profitability of our operations is influenced by the condition
of the U.S. and European economies, including fluctuations in currency
exchange rates, that may impact the demand for leisure travel and our
competitive pricing position. The majority of our charter and scheduled
airline business, other than military, is leisure travel. Because leisure
travel is discretionary, we have historically tended to experience somewhat
weaker financial results during economic downturns and other events affecting
international leisure travel, such as the Persian Gulf War. Nevertheless, our
performance during these periods have been significantly better than that of
the U.S. airline industry as a whole.

          The airline industry is heavily regulated, and changes in our
governmental authorizations or certificates, or changes in governmental
regulations, could adversely impact our business.

          We are subject to a wide range of governmental regulation, including
regulation by the Department of Transportation and the Federal Aviation
Administration. A modification, suspension or revocation of any of our
Department of Transportation or Federal Aviation Administration authorizations
or certificates could adversely impact our business.

          The Department of Transportation principally regulates economic
matters affecting air service, including:

          o    air carrier certification and fitness;

          o    insurance;


                                      16


<PAGE>


          o    leasing arrangements;

          o    allocation of route rights and authorization of proposed
               scheduled and charter operations;

          o    allocation of landing slots and departure slots;

          o    consumer protection; and

          o    competitive practices.

The Federal Aviation Administration primarily regulates flight operations,
especially matters affecting air safety, including airworthiness
requirements for each type of aircraft and pilot and crew certification.

          Under the Airport Noise and Capacity Act of 1990 and related Federal
Aviation Administration regulations, our aircraft must comply with specified
Stage 3 noise restrictions by specified deadlines. The regulations required
that we achieve a 75% Stage 3 fleet by December 31, 1998, and will prohibit us
from operating any Stage 2 aircraft after December 31, 1999. As of December
31, 1998, 83.3% of our fleet met Stage 3 requirements. We expect to meet
future Stage 3 requirements through Boeing 727-200 hushkit modifications,
combined with additional future deliveries of Stage 3 aircraft. We believe we
are in compliance with all requirements necessary to maintain in good standing
our operating authority granted by the Department of Transportation and our
air carrier operating certificate issued by the Federal Aviation
Administration.

          The Federal Aviation Administration has issued a series of
airworthiness directives under its aging aircraft program. These directives
are applicable to our Lockheed L-1011 and Boeing 727-200 aircraft. We do not
currently expect that the cost of compliance with these directives will be
material.

          Changes in governmental regulation could also adversely impact our
business. In recent years, for example, the Federal Aviation Administration
has issued or proposed mandates relating to, among other things:

          o    collision avoidance systems;

          o    airborne windshear avoidance systems;

          o    noise abatement; and

          o    increased inspections and maintenance procedures.

          We expect to incur expenses as we try to comply with changes in
Federal Aviation Administration regulations, particularly those relating to
noise and aging aircraft. The Federal Aviation Administration requires each
carrier to obtain an operating certificate and operations specifications
authorizing the carrier to fly to specific airports using specified equipment.

          Several aspects of airline operations are subject to regulation or
oversight by federal agencies other than the Department of Transportation and
the Federal Aviation Administration. For example, the U.S. Postal Service has
jurisdiction over certain aspects of the transportation of mail and related
services that we provide through our cargo affiliate. Labor relations in the
air transportation industry are generally regulated under the Railway Labor
Act, which vests in the National Mediation Board regulatory powers with
respect to disputes between airlines and labor unions arising under collective
bargaining agreements.

          We are also subject to the jurisdiction of the Federal
Communications Commission regarding the use of radio facilities. In addition,
we are subject to regulation on international flights by the Commerce
Department, the Customs Service, the Immigration and Naturalization Service
and the Animal and Plant Health Inspection Service of the Department of
Agriculture. Also, while our aircraft are in foreign countries, we must comply
with the requirements of similar authorities in those countries. We are also
subject to compliance with standards for aircraft exhaust emissions
promulgated by the Environmental Protection Agency and with regulations
adopted by various local authorities that operate the airports we serve
throughout our route network, including aircraft noise regulations and
curfews. The Commerce Department also regulates the export and re-export of
our U.S. manufactured aircraft and equipment. While we intend


                                      17


<PAGE>



to maintain all appropriate government licenses and to comply with all
appropriate standards, we cannot assure you that we will be successful.

          In addition to various federal regulations, local governments and
authorities in certain markets have adopted regulations governing various
aspects of aircraft operations, including noise abatement, curfews and use of
airport facilities. Many U.S. airports have adopted or are considering
adopting a passenger facility charge of up to $3.00 generally payable by each
passenger departing from the airport. This charge must be collected from
passengers by transporting air carriers and must be remitted to the applicable
airport authority. Airport operators must obtain approval of the Federal
Aviation Administration before they may implement a passenger facility charge.
The $3.00 maximum on passenger facility charges must be raised if Congress
enacts an amendment to the legislation authorizing these charges.

          We are subject to biennial inspections by the Department of Defense
as a condition of retaining our eligibility to perform military charter
flights. The last such inspection was completed in September of 1999. As a
result of our military business, we have been required from time to time to
meet operational standards beyond those normally required by the Department of
Transportation, the Federal Aviation Administration and other government
agencies.

          At our aircraft line maintenance facilities, we use materials that
are regulated as hazardous under federal, state and local laws. We are
required to maintain programs to protect the safety of our employees who use
these materials and to manage and dispose of any waste generated by the use of
these materials in compliance with these laws. More generally, we are also
subject at these facilities to federal, state and local regulations relating
to protection of the environment and to discharge of materials in the
environment. We do not expect that the costs associated with ongoing
compliance with any of these regulations will have a material impact upon our
capital expenditures, earnings, or competitive position. Additional laws and
regulations have been proposed from time to time that could significantly
increase the cost of airline operations by, for instance, imposing additional
requirements or restrictions or operations. In addition, laws and regulations
have been considered from time to time that would prohibit or restrict the
ownership and/or transfer of airline routes or takeoff and landing slots.

          Based upon bilateral aviation agreements between the U.S. and other
nations, and, in the absence of such agreements, comity and reciprocity
principles, we, as a charter carrier, are generally not restricted as to the
frequency of our flights to and from most foreign destinations. However, these
agreements generally restrict us to the carriage of passengers and cargo on
flights which either originate in the U.S. and terminate in a single foreign
nation or which originate in a single foreign nation and terminate in the U.S.
Proposals for any additional charter service must generally be specifically
approved by the civil aeronautics authorities in the relevant countries.
Approval of these requests is typically based on considerations of comity and
reciprocity and cannot be guaranteed.

Risk Factors Relating to the Notes

 Your Exchange Notes will be effectively subordinated to secured obligations
                             of our subsidiaries.

          Claims of secured creditors of our subsidiaries have priority to
the extent of the security interests granted in the assets of those
subsidiaries over our claims and claims of the Holders of our indebtedness,
including your Exchange Notes. ATA is presently the borrower under a $100.0
million secured revolving credit facility, which provides for a $100.0
million (including up to $50.0 million for stand-by letters of credit)
revolving line of credit for general working capital purposes. Amounts owed
under our bank credit facility are secured by a first priority perfected
security interest in certain aircraft and related engines. Accordingly, the
lenders under our bank credit facility have priority over your claims and
claims of other Holders of the Exchange Notes with respect to, and to the
extent of, the pledged assets. Thus, the Exchange Notes are effectively
subordinated to such secured indebtedness, and to any other secured
indebtedness, of our subsidiaries.

          In addition the Exchange Notes will be effectively subordinated to
the claims of creditors of any of our subsidiaries that are not Guarantors.

       We may be unable to purchase your Notes upon a change of control.

          Upon the occurrence of a change of control, you may require us to
repurchase all or a portion of your Exchange Notes at 101% of the principal
amount of the Notes, together with accrued and unpaid interest to


                                      18


<PAGE>


the date of repurchase. If a change of control were to occur, we may not have
the financial resources to repay the Notes, our credit facilities and any
other indebtedness that would become payable upon the occurrence of such
change of control. The "Repurchase of Notes upon a Change of Control" covenant
requiring us to repurchase the Notes will, unless consents are obtained,
require us to repay all indebtedness then outstanding in the event of a change
of control. There can be no assurance that we will have sufficient funds
available at the time of any change of control to make any debt payment
(including repurchase of Notes) required by this covenant. See "Description of
the Notes-Repurchase of Notes upon a Change of Control" and "Description of
the New Credit Facility."

  The Notes and the Note Guarantees are subject to fraudulent transfer laws.

          Under federal or state fraudulent transfer laws, if a court were to
find, in a lawsuit by an unpaid creditor or a representative of creditors, a
trustee in bankruptcy or a debtor-in-possession, that we issued the Notes with
the intent to hinder, delay or defraud present or future creditors, or
received less than a reasonably equivalent value or fair consideration for any
such indebtedness, and at the time of such incurrence:

          o    were insolvent;

          o    were rendered insolvent by reason of such incurrence;

          o    were engaged or about to engage in a business or transaction
               for which its remaining assets constituted unreasonably small
               capital to carry on its business; or

          o    intended to incur, or believed or reasonably should have
               believed that we would incur, debts beyond our ability to pay
               as such debts matured,

such court could avoid our obligations to you under the Notes, subordinate
our obligations to you to all other indebtedness or take other action
detrimental to you. In that event, there can be no assurance that any
repayment of principal and accrued interest on the Notes could ever be
recovered by you. Any Guarantee may also be subject to challenge under
fraudulent transfer laws and, in any case, will be limited to amounts that
any such Guarantor can guarantee without violating such laws. See
"Description of the Notes-Guarantee."

                    There is no public market for the Notes

          We are obligated to complete this exchange offer for the Notes or to
register the Notes under the Securities Act prior to May 19, 2000, 150 days
after the Closing Date of the December 21, 1999 private placement. However,
there can be no assurance that such exchange or registration will occur in the
required time period. The Securities and Exchange Commission (the
"Commission") has broad discretion to determine whether any registration
statement will be declared effective and may delay or deny effectiveness of
any such registration statement filed by us for a variety of reasons. Failure
to have the registration statement declared effective could adversely affect
the liquidity and price of the Notes. See "Description of the Notes" and
"Transfer Restrictions."

                           Exchange Offer Procedures

          Issuance of the Exchange Notes to you in exchange for your
Outstanding Notes pursuant to the exchange offer will be made only after our
timely receipt of Outstanding Notes, a properly completed and duly executed
Letter of Transmittal or an Agent's Message (as defined herein) in lieu
thereof and all other required documents. Therefore, if you desire to tender
your Outstanding Notes in exchange for Exchange Notes you should allow
sufficient time to ensure timely delivery. We are not required to give
notification of defects or irregularities with respect to the tenders of
Outstanding Notes for exchange. Outstanding Notes that are not tendered or are
tendered but not accepted will, following the consummation of the exchange
offer, continue to be subject to the existing restrictions on transfer
thereof. See "The Exchange Offer."

             Consequences of Failure to Exchange and Requirements
                        for Transfer of Exchange Notes

          Holders of Outstanding Notes who do not exchange them for Exchange
Notes in the exchange offer will continue to be subject to the provisions in
the Indenture regarding transfer and exchange of the Outstanding Notes and the
restrictions on transfer of such Outstanding Notes as set forth in the legend
thereon as a consequence of the issuance of the Outstanding Notes pursuant to
exemptions from, or in


                                      19


<PAGE>


transactions not subject to, the registration requirements of the
Securities Act and applicable state securities laws.

          In general, the Outstanding Notes may not be offered or sold, unless
registered under the Securities Act, except pursuant to an exemption from, or
in a transaction not subject to, the Securities Act and applicable state
securities laws. We do not currently anticipate that we will register
Outstanding Notes under the Securities Act.

          Based on interpretations by the staff of the Commission, as set
forth in no-action letters issued to third parties, we believe that Exchange
Notes issued in the exchange offer in exchange for Outstanding Notes may be
offered for resale, resold or otherwise transferred by Holders thereof (other
than any such Holder which is an "affiliate" of the Company within the meaning
of Rule 405 under the Securities Act) without compliance with the registration
and prospectus delivery provisions of the Securities Act, if Exchange Notes
are acquired in the ordinary course of the Holders' business and such Holders
have no arrangement with any person to participate in the distribution of such
Exchange Notes.

          However, the Company does not intend to request the Commission to
consider, and the Commission has not considered, the exchange offer in the
context of a no-action letter and there can be no assurance that the staff of
the Commission would make a similar determination with respect to the exchange
offer as in such other circumstances.

          Each Holder, other than a broker-dealer, must acknowledge that:

          (i) the Exchange Notes received by such Holder will be acquired in
     the ordinary course of its business;

          (ii) at the time of the consummation of the exchange offer such
     Holder will have not engaged in, and does not intend to engage in, a
     distribution of Exchange Notes and has no arrangement or understanding to
     participate in a distribution of Exchange Notes; and

          (iii) such Holder is not an affiliate of the Company within the
     meaning of Rule 405 of the Securities Act or if it is such an affiliate,
     that it will comply with the registration and prospectus delivery
     requirements of the Securities Act, to the extent applicable.

          If any Holder is an affiliate of the Company, is engaged in or
intends to engage in or has any arrangement or understanding with respect to
the distribution of the Exchange Notes to be acquired pursuant to the exchange
offer, such Holder

          (i) could not rely on the applicable interpretations of the staff of
     the Commission; and

          (ii) must comply with the registration and prospectus delivery
     requirement of the Securities Act in connection with any resale
     transaction.

          Each broker-dealer that receives Exchange Notes for its own account
in the exchange offer must acknowledge that it will deliver a prospectus in
connection with any resale of such Exchange Notes. The Letter of Transmittal
states that by so acknowledging and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within
the meaning of the Securities Act.

          This prospectus, as it may be amended or supplemented from time to
time, may be used by a broker-dealer in connection with resales of Exchange
Notes received in exchange for Outstanding Notes, where such Outstanding Notes
were acquired by such broker-dealer as a result of market-making activities or
other trading activities. We have agreed that, for a period of 180 days after
the expiration date, it will make this prospectus available to any
broker-dealer for use in connection with any such resale. See "Plan of
Distribution."

          However, to comply with state securities laws, the Exchange Notes
may not be offered or sold in any state unless they have been registered or
qualified for sale in such state or an exemption from registration or
qualification is available and is complied with. The offer and sale of the
Exchange Notes to "qualified institutional buyers" (as such term is defined
under Rule 144A of the Securities Act) is generally exempt from registration
or qualification under state securities laws. The Company currently does not
intend to register or qualify the sale of the Exchange Notes in any state
where an exemption from registration or


                                      20


<PAGE>




qualification is required and not available. See "The Exchange
Offer--Consequences of Failure to Exchange and Requirements for Transfer for
Exchange Notes."

                              THE EXCHANGE OFFER

Terms of the Exchange Offer; Period for Tendering Outstanding Notes

          Subject to the terms and conditions in this prospectus and in the
accompanying Letter of Transmittal, we will exchange unregistered Outstanding
Notes properly tendered on before the expiration date and not withdrawn for
registered Exchange Notes. The expiration date is midnight, New York City
time, on [ ] unless we extend it.

          As of the date of this prospectus, $75,000,000 aggregate principal
amount of the Outstanding Notes is outstanding. This prospectus, together with
the Letter of Transmittal, is first being sent on or about [ ], to all Holders
of Outstanding Notes known to us. Our obligation to accept Outstanding Notes
for exchange is subject to certain conditions as set forth below under
"--Certain Conditions to the Exchange Offer."

          We may, at any time or from time to time, extend the expiration
date, by giving oral or written notice of such extension in the manner
described below. During any such extension, all Outstanding Notes previously
tendered will remain subject to the exchange offer and we may accept them for
exchange. Any Outstanding Notes that we do not accept for exchange for any
reason will be returned to you without cost as promptly as practicable after
the expiration or termination of the exchange offer.

          Outstanding Notes tendered in the exchange offer must be in
denominations of principal amounts of $1,000 and any integral multiples
thereof.

          We expressly reserve the right to amend or terminate the exchange
offer. We also reserve the right to refuse for exchange any Outstanding Notes
not theretofore accepted for exchange, if any of the events specified below
under "--Certain Conditions to the Exchange Offer" occur. We will give oral or
written notice of any extension, amendment, non-acceptance or termination to
you as promptly as practicable any notice with respect to any extension will
be issued by means of press release or other public announcement no later than
9:00 a.m., New York City time, on the next business day after the previously
scheduled expiration date.

Procedures for Tendering Outstanding Notes

          Certificates for such Outstanding Notes must be received by:

          (i) the Exchange Agent along with the Letter of Transmittal; or

          (ii) a timely confirmation of a book-entry transfer of the
     Outstanding Notes, if such procedure is available, into the Exchange
     Agent's account at The Depository Trust Company pursuant to the procedure
     for book-entry transfer described below, must be received by the Exchange
     Agent prior to the expiration date with the Letter of Transmittal or
     Agent's Message in lieu of such Letter of Transmittal; or

          (iii) the Holder must comply with the guaranteed delivery procedures
     described below.

          The term Agent's Message means a message, transmitted by the
Book-Entry Transfer Facility to and received by the Exchange Agent. It forms a
part of a Book-Entry Confirmation, which states that the Book-Entry Transfer
Facility has received an express acknowledgment from the tendering
participant, which states that the participant has received and agrees to be
bound by the Letter of Transmittal and that we may enforce the Letter of
Transmittal against such participant. THE METHOD OF DELIVERY OF THE
OUTSTANDING NOTES, THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS
IS AT THE ELECTION AND RISK OF THE HOLDERS. IF SUCH DELIVERY IS BY MAIL, IT IS
RECOMMENDED THAT REGISTERED MAIL, PROPERLY INSURED, WITH RETURN RECEIPT
REQUESTED, BE USED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE
TIMELY DELIVERY. DELIVERY OF DOCUMENTS TO DTC IN ACCORDANCE WITH ITS
PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT. NO LETTER OF
TRANSMITTAL OR OUTSTANDING NOTES SHOULD BE SENT TO US.


                                      22


<PAGE>


          Signatures on a Letter of Transmittal or a notice of withdrawal, as
the case may be, must be guaranteed by:

          o    a member firm of a registered national securities exchange or
               of the National Association of Securities Dealers, Inc.;

          o    a commercial bank; or

          o    a trust company having an office or correspondent in the United
               States (collectively, Eligible Institutions);

unless the Outstanding Notes tendered are tendered:

          (i) by a registered Holder of the Outstanding Notes who has not
     completed the box entitled "Special Issuance Instructions" or "Special
     Delivery Instructions" on the Letter of Transmittal; or

          (ii) for the account of an Eligible Institution.

     If Outstanding Notes are registered to a person who did not sign the
Letter of Transmittal, the Outstanding Notes surrendered for exchange must
be endorsed by, or be accompanied by a written transfer or exchange, duly
executed by the registered Holder with the signature guaranteed by an
Eligible Institution. All questions of satisfaction of the form of the
writing will be determined by us in our sole discretion.

          If the Letter of Transmittal is signed by a person other than the
registered Holder of any Outstanding Notes listed therein, such Outstanding
Notes must be endorsed or accompanied by appropriate powers of attorney,
signed exactly as the name of the registered Holder appears on the Outstanding
Notes.

          If the Letter of Transmittal or any Outstanding Notes or powers of
attorney are signed by trustees, executors, administrators, guardians,
attorneys-in-fact, officers of corporations or others acting in a fiduciary or
representative capacity, such persons should so indicate when signing, and
unless waived by us, evidence satisfactory to us of their authority to so act
must be submitted with the Letter of Transmittal.

          We will determine all questions as to the validity, form,
eligibility (including time of receipt), acceptance and withdrawal of the
tendered Outstanding Notes. Our determination will be final and binding. We
reserve the absolute right to reject any and all tenders of any particular
Outstanding Notes not properly tendered or to not accept any particular
Outstanding Notes our acceptance of which would, in our opinion or in the
opinion of our counsel, be unlawful. We also reserve the absolute right to
waive any defects or irregularities or conditions of the exchange offer as to
any particular Outstanding Notes either before or after the expiration date.

          Our interpretation of the terms and conditions of the exchange offer
(including the instructions in the Letter of Transmittal) will be final and
binding on all parties. Unless waived, any defects or irregularities in
connection with tenders of Outstanding Notes must be cured within a time
period we determine. Neither we, the Exchange Agent nor any other person is
under any duty to give notification of defects or irregularities with respect
to tenders of Outstanding Notes nor shall any of them incur any liability for
failure to give such notification. Any Outstanding Notes will not be
considered to have been properly tendered until such defects or irregularities
have been cured or waived. Any Outstanding Notes received by the Exchange
Agent that are not properly tendered and as to which the defects or
irregularities have not been cured or waived will be returned without cost by
the Exchange Agent to the tendering Holders unless otherwise provided in the
Letter of Transmittal as soon as practicable following the expiration date.

          In addition, we reserve the right in our sole discretion to:

          (i) purchase or make offers for any Outstanding Notes that remain
     outstanding subsequent to the expiration date, or, as set forth under
     "--Certain Conditions to the Exchange Offer," to terminate the exchange
     offer; and

          (ii) to the extent permitted by applicable law, purchase Outstanding
     Notes in the open market, in privately negotiated transactions or
     otherwise. The terms of any such purchases or offers may differ from the
     terms of the exchange offer.


                                      23


<PAGE>


By tendering, each Holder of Outstanding Notes will represent to us, among
other things that:

          o    the Exchange Notes acquired pursuant to the exchange offer are
               being obtained in the ordinary course of business of the person
               receiving the Exchange Notes, whether or not that person is the
               Holder;

          o    neither the Holder nor any other person has any arrangement or
               understanding with any person to participate in the
               distribution of the Exchange Notes; and

          o    such Holder is not engaged in, or intends to engage in, a
               distribution of the Exchange Notes.

          If any Holder or any such other person is an "affiliate," as defined
under Rule 405 of the Securities Act, of the Company, or is engaged in or
intends to engage in or has an arrangement or understanding with any person to
participate in a distribution of such Exchange Notes to be acquired in the
exchange offer, such Holder or any such other person:

          (i) could not rely on the applicable interpretations of the staff of
     the Commission; and

          (ii) must comply with the registration and prospectus delivery
     requirements of the Securities Act in connection with any resale
     transaction. Each broker-dealer that receives Exchange Notes for its own
     account in exchange for Outstanding Notes, where such Outstanding Notes
     were acquired by the broker-dealer as a result of market-making
     activities or other trading activities, must acknowledge that it will
     deliver a prospectus in connection with any resale of such Exchange
     Notes. See "Plan of Distribution."

Acceptance of Outstanding Notes for Exchange; Delivery of Exchange Notes

          Upon satisfaction or waiver of the conditions to the exchange offer,
we will accept, promptly, all Outstanding Notes properly tendered and will
issue the Exchange Notes. See "--Certain Conditions to the Exchange Offer."

          We are deemed to have accepted properly tendered Outstanding Notes
for exchange if or when we give oral or written notice of acceptance to the
Exchange Agent, with written confirmation of any oral notice to follow
promptly.

          For each Outstanding Note accepted for exchange, Holders of that
Outstanding Note will receive an Exchange Note having a principal amount equal
to that of the surrendered Outstanding Note. Interest on the Outstanding Notes
will accrue from the most recent interest payment date or if no interest has
been paid, from December 21, 1999. Interest on the Outstanding Notes and the
Exchange Notes is payable semi-annually on February 1 and August 1. Holders of
Outstanding Notes whose Outstanding Notes are accepted for exchange will be
deemed to have waived the right to receive any payment in respect of accrued
and unpaid interest on the Outstanding Notes accrued from the most recent
interest payment date or if no interest has been paid, from December 21, 1999
to the date of the issuance of the Exchange Notes. The Exchange Notes will
entitle Holders to receive any interest payment that would have otherwise been
payable with respect to the Outstanding Notes. Consequently, Holders who
exchange their Outstanding Notes for Exchange Notes will receive the same
interest payment on August 1, 2000 (the first interest payment date with
respect to the Outstanding Notes and the Exchange Notes occurring after the
closing of the exchange offer) that they would have received had they not
accepted the exchange offer.

          In all cases, issuance of Exchange Notes for Outstanding Notes that
are accepted for exchange will be made only after timely receipt by the
Exchange Agent of:

          (i) certificates for such Outstanding Notes or a timely Book-Entry
     Confirmation of such Outstanding Notes into the Exchange Agent's account
     at the Book-Entry Transfer Facility;

          (ii) a properly completed and duly executed Letter of Transmittal or
     an Agent's Message in lieu thereof; and

          (iii) all other required documents.

If any tendered Outstanding Notes are not accepted for any reason set forth
in the terms and conditions of the exchange offer or if Outstanding Notes
are submitted for a greater principal amount than the Holder


                                      24


<PAGE>


desired to exchange, the unaccepted or non-exchanged Outstanding Notes will
be returned without expense to the tendering Holder (or, in the case of
Outstanding Notes tendered by book-entry transfer into the Exchange Agent's
account at the Book-Entry Transfer Facility pursuant to the book-entry
procedures described below, the non-exchanged Outstanding Notes will be
credited to an account maintained with such Book-Entry Transfer Facility)
as promptly as practicable after the expiration or termination of the
exchange offer.

Book-Entry Transfer

          The Exchange Agent will make a request to establish an account with
respect to the Outstanding Notes at the Book-Entry Transfer Facility for
purposes of the exchange offer within two business days after the date of this
prospectus. Any financial institution that is a participant in the Book-Entry
Transfer Facility's systems may make book-entry delivery of Outstanding Notes
by causing the Book-Entry Transfer Facility to transfer the Outstanding Notes
into the Exchange Agent's account at the Book-Entry Transfer Facility in
accordance with the Book-Entry Transfer Facility's procedures for transfer.
However, although delivery of Outstanding Notes may be effected through
book-entry transfer at the Book-Entry Transfer Facility, the Letter of
Transmittal (or a facsimile thereof or an Agent's Message in lieu thereof),
with any required signature guarantees and any other required documents, must
still be transmitted to and received by the Exchange Agent at one of the
addresses set forth below, under "--Exchange Agent" on or prior to the
expiration date or the guaranteed delivery procedures described below must be
complied with.

Guaranteed Delivery Procedures

          A Holder who wishes to tender its Outstanding Notes; and

          (i) whose Outstanding Notes are not immediately available; or

          (ii) who cannot deliver their Outstanding Notes, the Letter of
     Transmittal, or any other required documents to the Exchange Agent prior
     to the expiration date; or

          (iii) who cannot complete the procedure for book-entry transfer on a
     timely basis, may effect a tender if:

               (a) the tender is made through an Eligible Institution; and

               (b) before the expiration date, the Exchange Agent receives
          from the Eligible Institution:

                    o    a properly completed and duly executed Notice of
                         Guaranteed Delivery (by facsimile transmission, mail
                         or hand delivery) setting forth the name and address
                         of the Holder of the Outstanding Notes;

                    o    the certificate number or numbers of such Outstanding
                         Notes and the principal amount of Outstanding Notes
                         tendered, stating that the tender is being made
                         thereby, and guaranteeing that the certificates for
                         all physically tendered Outstanding Notes, in proper
                         form for transfer, or a Book-Entry Confirmation, as
                         the case may be, together with a properly completed
                         and duly executed Letter of Transmittal (or a
                         facsimile thereof or an Agent's Message in lieu
                         thereof) with any required signature guarantees, and
                         all other documents required by the Letter of
                         Transmittal are received by the Exchange Agent within
                         three NYSE trading days after the date of execution
                         of the Notice of Guaranteed Delivery; and

                    o    the certificates for all physically tendered
                         Outstanding Notes, in proper form for transfer, or a
                         Book-Entry Confirmation, as the case may be, together
                         with a properly completed and duly executed Letter of
                         Transmittal (or a facsimile thereof or an Agent's
                         Message in lieu thereof), with any required signature
                         guarantees and any other documents required by the
                         Letter of Transmittal, that will be deposited by the
                         Eligible Institution with the Exchange Agent within
                         three New York Stock Exchange trading days after the
                         date of execution of the Notice of Guaranteed
                         Delivery.

Withdrawal of Rights

     Except as otherwise provided herein, tenders of Outstanding Notes may be
withdrawn at any time prior to midnight, New York City time, on the expiration
date.

     To withdraw a tender of outstanding Notes, a written notice of
withdrawal must be received by the Exchange Agent at its address set forth
herein prior to midnight, New York City time, on the expiration date. Any
such notice of withdrawal must:

          (i) specify the name of the person having tendered the Outstanding
     Notes to be withdrawn (the Depositor);

          (ii) include a statement that the Depositor is withdrawing its
     election to have Outstanding Notes exchanged, and identify the
     Outstanding Notes to be withdrawn (including the certificate number or
     numbers and principal amount of such Outstanding Notes); and

          (iii) where certificates for Outstanding Notes have been
     transmitted, specify the name in which such Outstanding Notes are
     registered, if different from that of the withdrawing Holder.

     If certificates for Outstanding Notes have been delivered or otherwise
identified to the Exchange Agent, then, prior to the release of such
certificates the withdrawing Holder must also submit:

          (i) the serial numbers of the particular certificates to be
     withdrawn; and

          (ii) signed notice of withdrawal with signatures guaranteed by an
     Eligible Institution unless such Holder is an Eligible Institution.

     If Outstanding Notes have been tendered pursuant to the procedure for
book-entry transfer described above, any notice of withdrawal must specify the
name and number of the account at the Book-Entry Transfer Facility to be
credited with the withdrawn Outstanding Notes and otherwise comply with the
procedures of the facility.

     We will determine all questions as to the validity, form and eligibility
(including time of receipt) for such withdrawal notices. Our determination
shall be final and binding on all parties.

     Any Outstanding Notes so withdrawn will be considered not to have been
validly tendered for purposes of the exchange offer and no Exchange Notes will
be issued with respect thereto unless the Outstanding Notes so withdrawn are
validly retendered.

     Any Outstanding Notes which have been tendered but which are not
accepted for exchange for any reason will be returned to the Holder without
cost (or, in the case of Outstanding Notes tendered by book-entry transfer
into the Exchange Agent's account at the Book-Entry Transfer Facility
pursuant to the book-entry transfer procedures described above, such
Outstanding Notes will be credited to an account maintained with such
Book-Entry Transfer Facility for the Outstanding Notes) as soon as
practicable after withdrawal, rejection of tender or termination of the
exchange offer. Properly withdrawn Outstanding Notes may be retendered by
following one of the procedures described above under "--Procedures for
Tendering Outstanding Notes" at any time prior to midnight, New York City
time, on the expiration date.

Certain Conditions to the Exchange Offer

     The exchange offer is not subject to any conditions, other than that the
exchange offer does not violate applicable law or any applicable
interpretation of the staff of the Commission. We cannot assure you that any
such condition will not occur. Holders of Outstanding Notes will have certain
rights against us under the registration rights agreement should we fail to
consummate the exchange offer.

     If we determine that we may terminate the exchange offer, as set forth
above, we may:

          (i) refuse to accept any Outstanding Notes and return any
     Outstanding Notes that have been tendered;


                                      26


<PAGE>




          (ii) extend the exchange offer and retain all Outstanding Notes
     tendered prior to the expiration date, subject to the rights of such
     Holders of tendered Outstanding Notes to withdraw their tendered
     Outstanding Notes; or

          (iii) waive a termination event with respect to the exchange offer
     and accept all properly tendered Outstanding Notes that have not been
     withdrawn. If such waiver constitutes a material change in the exchange
     offer, we will disclose that change through a supplement to this
     prospectus that will be distributed to each registered Holder of
     Outstanding Notes. In addition, we will extend the exchange offer for a
     period of five to ten business days, depending upon the significance of
     the waiver and the manner of disclosure to the registered Holders of the
     Outstanding Notes, if the exchange offer would otherwise expire during
     such period.

Fees and Expenses

          We will not make any payments to brokers, dealers or other persons
soliciting acceptances of the exchange offer.

          The estimated cash expenses to be incurred in connection with the
exchange offer will be paid by us and are estimated to be [$200,000].

Transfer Taxes

          Holders who tender their Outstanding Notes for exchange will not be
obligated to pay any transfer taxes in connection with the exchange. However
Holders who instruct us to register Exchange Notes in the name of, or request
that Outstanding Notes not tendered or not accepted in the exchange offer be
returned to, a person other than the registered tendering Holder will be
responsible for the payment of any applicable transfer tax thereon.

Consequences of Exchanging Outstanding Notes

          Holders of Outstanding Notes who do not exchange them for Exchange
Notes in the exchange offer will continue to be subject to the provisions in
the Indenture regarding their transfer and exchange. Any outstanding Notes not
exchanged will continue to accrue interest, but will not retain any rights
under the registration rights agreement and will bear the legend which sets
forth the restrictions on transfer to which they are subject as a consequence
of the issuance of the Outstanding Notes pursuant to exemptions from, or in
transactions not subject to, the registration requirements of the Securities
Act and applicable state securities laws.


                                      27

          In general, the Outstanding Notes may not be offered or sold, unless
registered under the Securities Act, except pursuant to an exemption from, or
in a transaction not subject to, the Securities Act and applicable state
securities laws. We do not currently anticipate that we will register
Outstanding Notes under the Securities Act. See "Registration Rights for
Outstanding Notes."

          Based on interpretations by the staff of the Commission, as set
forth in no-action letters issued to third parties, we believe that Exchange
Notes issued in the exchange offer in exchange for Outstanding Notes may be
offered for resale, resold or otherwise transferred by Holders thereof (other
than any such Holder which is an "affiliate" of the Company within the meaning
of Rule 405 under the Securities Act) without compliance with the registration
and prospectus delivery provisions of the Securities Act, provided that such
Exchange Notes are acquired in the ordinary course of such Holders' business
and such Holders have no arrangement with any person to participate in the
distribution of such Exchange Notes.

          However, we do not intend to request the Commission to consider, and
the Commission has not considered, the exchange offer in the context of a
no-action letter and there can be no assurance that the staff of the
Commission would make a similar determination with respect to the exchange
offer as in such other circumstances. Each Holder, other than a broker-dealer,
must acknowledge that:

          (i) the Exchange Notes received by such Holder will be acquired in
     the ordinary course of its business;

          (ii) at the time of the consummation of the exchange offer such
     Holder will have not engaged in, and does not intend to engage in, a
     distribution of Exchange Notes and has no arrangement or understanding to
     participate in a distribution of Exchange Notes; and

          (iii) such Holder is not an affiliate of the Company within the
     meaning of Rule 405 of the Securities Act or if it is such an affiliate,
     that it will comply with the registration and prospectus delivery
     requirements of the Securities Act, to the extent applicable.

          If any Holder is an affiliate of the Company, is engaged in or
intends to engage in or has any arrangement or understanding with respect to
the distribution of the Exchange Notes to be acquired pursuant to the exchange
offer, such Holder:

          (i) could not rely on the applicable interpretations of the staff of
     the Commission; and

          (ii) must comply with the registration and prospectus delivery
     requirement of the Securities Act in connection with any resale
     transaction.

          Each broker-dealer that receives Exchange Notes for its own account
in exchange for Outstanding Notes must acknowledge that such Outstanding Notes
were acquired by such broker-dealer as a result of market-making activities or
other trading activities and that it will deliver a prospectus in connection
with any resale of such Exchange Notes.

          The Letter of Transmittal states that by so acknowledging and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it
is an "underwriter" within the meaning of the Securities Act.

          This prospectus, as it may be amended or supplemented from time to
time, may be used by a broker-dealer in connection with resales of Exchange
Notes received in exchange for Outstanding Notes, where such Outstanding Notes
were acquired by such broker-dealer as a result of market-making activities or
other trading activities.

          We have agreed that for a period of 180 days after the expiration
date, we will make this prospectus available to any broker-dealer for use in
connection with any such resale. See "Plan of Distribution."

          In addition, to comply with state securities laws, the Exchange
Notes may not be offered or sold in any state unless they have been registered
or qualified for sale in such state or an exemption from registration or
qualification is available and is complied with.

          The offer and sale of the Exchange Notes to "Qualified Institutional
Buyers" (as such term is defined under Rule 144A of the Securities Act) is
generally exempt from registration or qualification under state


                                      28


<PAGE>


securities laws. We currently do not intend to register or qualify the sale
of the Exchange Notes in any state where an exemption from registration or
qualification is required and not available.


                                USE OF PROCEEDS

          There will be no cash payable proceeds to us from the exchange
offer. The exchange offer is intended to satisfy certain of our obligations
under the registration rights agreement.

          In consideration for issuing the Exchange Notes contemplated in this
prospectus, we will receive Outstanding Notes in like principal amount, the
form and terms of which are the same as the form and terms of the Exchange
Notes (which they replace), except as otherwise described herein. The
Outstanding Notes surrendered in exchange for Exchange Notes will be retired
and canceled and cannot be reissued. Accordingly, the issuance of the Exchange
Notes will not result in any increase or decrease in the indebtedness of the
Company.

          The net proceeds of the private placement were approximately $73.0
million and were used by the Company to repay bank indebtedness and for
general corporate purposes, which may include the purchase of additional
aircraft and the refinancing of existing aircraft.

     (1)  Amtran has reclassified gain (loss) on the sale of operating assets
          for 1994-1995 from non-operating gain (loss) to operating income
          (loss) to be consistent with the 1996-1999 presentations. Also, in
          the third quarter of 1996, Amtran recorded a $4.7 million loss on
          the disposal of leased assets associated with the reconfiguration of
          its fleet.

     (2)  In 1997, Amtran adopted Financial Accounting Standards Board
          Statement 128, "Earnings per Share," which established new standards
          for the calculation and disclosure of earnings per share. All prior
          period amounts disclosed in this five-year summary have been
          restated to conform to the new standards under Statement 128.

     (3)  Non-cash working capital consists of total current assets (excluding
          cash) less total current liabilities (excluding current maturities
          of long-term debt).

     (4)  No dividends were paid in any of the periods presented.

     (5)  EBITDAR represents net income plus interest expense (net of
          capitalized interest), income tax expense, depreciation,
          amortization and aircraft rentals. EBITDA represents net income plus
          interest expense (net of capitalized interest), income tax expense,
          depreciation and amortization. EBITDAR and EBITDA are presented
          because each is a widely accepted financial indicator of a company's
          ability to incur and service debt. However, EBITDAR and EBITDA
          should not be considered in isolation, as a substitute for net
          income or cash flow data prepared in accordance with generally
          accepted accounting principles or as a measure of a company's
          profitability or liquidity.

     (6)  The "ratio of earnings to fixed charges" represents earnings divided
          by fixed charges, as defined in the following paragraph. The
          "deficiency" represents the amount of fixed charges in excess of
          earnings.

          For purposes of these computations, earnings consist of income
          (loss) before income taxes, plus fixed charges, adjusted to exclude
          the amount of any interest capitalized during the period. Fixed
          charges include the total of: (i) interest, whether expensed or
          capitalized; (ii) amortization of debt expense relating to any
          indebtedness, whether expensed or capitalized; and (iii) such
          portion of rental expense as can be demonstrated to be
          representative of the interest factor.

                  DESCRIPTION OF OTHER PRINCIPAL INDEBTEDNESS

Revolving Credit Facilities

         We maintain revolving credit facilities to assist us in managing
our working capital and in meeting our short-term cash needs.

          1998 Credit Facility. Under our 1998 credit facility, ATA is
designated as the borrower. The credit facility provides for maximum
borrowings of $50.0 million, including stand-by letters of credit in a maximum
amount of $25.0 million. All borrowings under the 1998 credit facility are
guaranteed by Amtran and all of its other operating subsidiaries and secured
by some of Amtran's L-1011 aircraft and engines, as well as specified
additional assets as may be required to provide a loan-to-value ratio not in
excess of 75%. The credit facility will mature, and all borrowings under the
credit facility will become due and payable, on April 1, 2001.

          So long as no event of default is continuing, borrowings under the
1998 credit facility bear interest, at the option of ATA, at either:

          o    LIBOR plus 1.50% to 2.50%, depending upon specified financial
               ratios; or

          o    the agent bank's prime rate.

In addition, ATA incurs a quarterly commitment fee ranging from 0.25% to
0.50% per annum on the average unused portion of the commitment, depending
upon specified ratios.

          1999 Credit Facility. In December 1999, we revised our 1998 credit
facility to provide for maximum borrowings of $100.0 million, including
stand-by letters of credit in a maximum amount of $50.0 million. All
borrowings under the 1999 credit facility are guaranteed by Amtran and all of
its other operating subsidiaries and secured by some of Amtran's L-1011
aircraft and engines, as well as specified additional assets as may be
required to provide a loan-to-value ratio not in excess of 75%. The 1999
credit facility will mature, and all borrowings under the credit facility will
become due and payable, on January 2, 2003.

          So long as no event of default is continuing, borrowings under the
1999 credit facility bear interest, at the option of ATA, at either:

          o    LIBOR plus 1.25% to 2.50%, depending upon specified financial
               ratios; or

          o    the agent bank's prime rate.

In addition, ATA incurs a quarterly commitment fee ranging from 0.25% to
0.50% per annum on the average unused portion of the commitment, depending
upon specified ratios.

          The credit facility contains covenants that, absent the prior
written consent of the lenders, limit the ability of ATA, Amtran and the other
guarantors to, among other things:

          o    incur debt;

          o    grant liens;

          o    make capital expenditures;

          o    pay dividends, distributions and other payments to
               stockholders;

          o    engage in mergers and similar business combinations;

          o    dispose of assets; and

          o    prepay debt.


                                      34


<PAGE>


In addition, for a specified period, ATA must maintain a number of
specified ratios, including minimum net worth, cash flow to interest
expense after rentals and total adjusted liabilities to tangible net worth.

          An event of default will occur if, among other things, a reduction
below 51% occurs in:

          o    Mr. Mikelsons' or his heirs' beneficial ownership of Amtran's
               outstanding capital stock;

or

          o    Amtran's beneficial ownership of ATA's outstanding capital
               stock.

9 5/8% Notes

          In 1998, Amtran issued $125.0 million principal amount of 9 5/8%
senior notes due 2005. All of Amtran's obligations under the 9 5/8% notes are
guaranteed by all of its operating subsidiaries, including ATA.

          Principal, Maturity and Interest. The 9 5/8% notes are limited in
aggregate principal amount to $125.0 million and will mature on December 15,
2005. Interest on the 9 5/8% notes accrues at 9 5/8% per annum and is payable
semiannually in cash on June 15 and December 15 of each year. Interest is
computed on the basis of a 360-day year comprised of twelve 30-day months.

          Ranking. The 9 5/8% notes are unsecured obligations of Amtran, rank
pari passu in right of payment with all existing and future unsecured
unsubordinated obligations of Amtran and rank senior in right of payment to
all existing and future subordinated obligations of Amtran. The 9 5/8% notes
are also effectively subordinated to all existing and future secured
indebtedness of Amtran and the guarantors to the extent of the security.

          Redemption. The 9 5/8% notes are redeemable, at Amtran's option, in
whole or in part, at any time on or after June 15, 2003, at the redemption
prices (expressed as percentages of principal amount) set forth below plus
accrued and unpaid interest thereon to the applicable redemption date, if
redeemed during the 12-month period beginning on June 15 of the year indicated
below:

Year                                                           Percentage
- ----                                                           ----------

2003......................................                      104.81%
2004......................................                      102.41%

          In addition, at any time prior to June 15, 2001, Amtran may redeem
up to 35% of the original aggregate principal amount of the 9 5/8% notes with
the proceeds of one or more sales of common stock, at a redemption price equal
to 109.625% of their principal amount plus accrued and unpaid interest, so
long as at least $81.25 million of aggregate principal amount of 9 5/8% notes
remains outstanding immediately after the redemption.

          Covenants. The indenture governing the 9 5/8% notes contains
covenants substantially identical to the covenants contained in the indenture
governing the 10 1/2% notes.

          Events of Default. The indenture governing the 9 5/8% notes contains
events of default substantially similar to those contained in the indenture
governing the 10 1/2% notes.

                           DESCRIPTION OF THE NOTES

          The Outstanding Notes were, and the Exchange Notes will be issued
under the Indenture, dated as of July 24, 1997, among the Company, as issuer,
American Trans Air, Inc., Ambassadair Travel Club, Inc., ATA Leisure Corp.
(formerly ATA Vacations, Inc.), Amber Travel, Inc., American Trans Air
Training Corporation, American Trans Air ExecuJet, Inc., Amber Air Freight
Corporation, and Chicago Express Airlines, Inc., as guarantors (collectively,
the Guarantors), and First Security Bank, N.A., as trustee (the Trustee), as
supplemented by the First Supplemental Indenture dated as of December 21, 1999
among the Company, the Guarantors and the Trustee (references in this
Description of Notes to the "Indenture" shall


                                      35


<PAGE>


mean the Indenture as so supplemented). The following summary of certain
provisions of the Indenture and the Exchange Notes does not purport to be
complete and is subject to, and is qualified in its entirety by reference
to, all the provisions of the Indenture, including the definitions of
certain terms therein and those terms made a part thereof by the Trust
Indenture Act of 1939, as amended (the Trust Indenture Act). A copy of the
Indenture and the Notes is available upon request from the Company.
Whenever particular defined terms of the Indenture not otherwise defined
herein are referred to, such defined terms are incorporated herein by
reference. For definitions of certain capitalized terms used in the
following summary, see "--Certain Definitions." For purposes of this
summary, unless the context indicates otherwise, the term "Notes" means the
Exchange Notes Holders will receive if they participate in this exchange
offer Notes.

General Aspects of the Exchange Notes

          Amtran, Inc. currently has outstanding $100,000,000 principal amount
of Exchange Notes that was issued in 1997 under a previous registered
statement. The Exchange Notes offered by this prospectus are part of the same
series of Exchange Notes that were issued in 1997.

          The Notes will be unsecured senior obligations of the Company, and
will mature on August 1, 2004. Each Note will initially bear interest at 10
1/2% per annum from the Closing Date, payable semiannually (to Holders of
record at the close of business on the January 15 or July 15 immediately
preceding the Interest Payment Date) on February 1 and August 1 of each year,
commencing February 1, 2000.

          If we have not (i) consummated a registered exchange offer for the
New Notes, or (ii) filed or caused a shelf registration statement with respect
to resales of the Notes to be declared effective within the time period
specified below, Holders will be entitled to certain additional interest. See
"--Registration Rights for Outstanding Notes."

          Principal of, premium, if any, and interest on the Notes will be
payable, and the Notes may be exchanged or transferred, at the office or
agency of the Company in the Borough of Manhattan, the City of New York;
provided that, at our option, payment of interest may be made by check mailed
to the Holders at their addresses as they appear in the Security Register.

          The Notes will be issued only in fully registered form, without
coupons, in denominations of $1,000 of principal amount and any integral
multiple thereof. See "-Book-Entry; Delivery and Form." No service charge will
be made for any registration of transfer or exchange of Notes, but we may
require payment of a sum sufficient to cover any transfer tax or other similar
governmental charge payable in connection therewith.

          Subject to the covenants described below under "Covenants" and
applicable law, we may issue additional Notes under the Indenture. The
Outstanding Notes, the Exchange Notes and any additional Notes subsequently
issued will be treated as a single class for all purposes under the Indenture.

Optional Redemption

          If more than 98% of the outstanding principal amount of the Notes
are tendered pursuant to an Offer to Purchase, as required by the "Limitation
on Asset Sales" or "Repurchase of Notes upon a Change of Control" covenant, we
have the option to redeem the balance of the Notes, in whole or in part, at

          Year                                                    Price

          2002.................................                  105.250%
          2003.................................                  102.625%

          In addition, at any time prior to August 1, 2000, we may redeem up
to 35% of the principal amount of the Notes with the proceeds of one or more
sales of its Common Stock, at any time or from time to time in part, at a
Redemption Price (expressed as a percentage of principal amount) of 110.500%,
plus accrued and unpaid interest to the Redemption Date (subject to the rights
of Holders of record on the relevant Regular Record Date that is prior to the
Redemption Date to receive interest due on an Interest Payment Date); so long
as at least 65% of the aggregate principal amount of Notes remains outstanding
after each such redemption.

          In the case of any partial redemption, selection of the Notes for
redemption will be made by the Trustee in compliance with the requirements of
the principal national securities exchange, if any, on which the Notes are
listed. If the Notes are not listed on a national securities exchange, the
redemption will be made by lot or by such other method as the Trustee in its
sole discretion shall deem to be fair and appropriate; so long as no Note of
$1,000 in principal amount or less shall be redeemed in part. If any Note is
to be redeemed in part only, the notice of redemption relating to such Note
must state the portion of the principal amount of the Note to be redeemed. A
new Note in principal amount equal to the unredeemed portion thereof will be
issued in the name of the Holder upon cancelation of the original Note.

Sinking Fund

There will be no sinking fund payments for the Notes.

Registration Rights for Outstanding Notes

          The Company and the Guarantors have agreed for the benefit of the
Holders, that they will use their best efforts, at their cost,

          (i) within 45 days after the Closing Date (the "Filing Date") of the
original offering, to file a registration statement (the exchange offer
registration statement) with respect to a registered offer (the exchange
offer) to exchange the Outstanding Notes for Exchange Notes with terms
identical to the Outstanding Notes (except that the Exchange Notes will not
bear legends restricting the transfer thereof); and

          (ii) cause the exchange offer registration statement to be declared
effective within 150 days after the Closing Date.

Once the registration statement is declared effective, the Company and the
Guarantors will offer the Exchange Notes in return for surrender of the
Outstanding Notes. The offer will remain open for at least 20 business days
after the date notice of the exchange offer is mailed to Holders. For each
Outstanding Note surrendered to us under the exchange offer, the Holder
will receive an Exchange Note of equal principal amount. Interest on each
Exchange Note shall accrue from the last Interest Payment Date on which
interest was paid on the Outstanding Notes so surrendered or, if no
interest has been paid on such Outstanding Notes, from the Closing Date.

          In the event that applicable interpretations of the staff of the
Commission do not permit the Company and the Guarantors to effect the exchange
offer, or under certain other circumstances, the Company and the Guarantors
shall, at their cost, use their best efforts to cause to become effective a
shelf registration statement (the "Shelf Registration Statement") with respect
to resales of the Notes and to keep such Shelf Registration Statement
effective until the expiration of the time period referred to in Rule 144(k)
under the Securities Act after the Closing Date, or such shorter period that
will terminate when all Outstanding Notes covered by the Shelf Registration
Statement have been sold pursuant to the Shelf Registration Statement. The
Company


                                      37


<PAGE>


and the Guarantors shall, in the event of such a shelf registration,
provide to each Holder copies of the prospectus, notify each Holder when
the Shelf Registration Statement for the Outstanding Notes has become
effective and take certain other actions as are required to permit resales
of the Outstanding Notes.

          A Holder that sells its Outstanding Notes pursuant to the Shelf
Registration Statement generally will be required to be named as a selling
security Holder in the related prospectus and to deliver a prospectus to
purchasers, will be subject to certain of the civil liability provisions under
the Securities Act in connection with such sales and will be bound by the
provisions of the registration rights agreement that are applicable to such a
Holder (including certain indemnification obligations).

          If we fail to comply with the above provisions or if the exchange
offer registration statement or the Shelf Registration Statement fails to
become effective, then additional interest shall become payable in respect of
the Outstanding Notes as follows:

         (1)   if:

               (A) neither the exchange offer registration statement nor the
Shelf Registration Statement is filed with the Commission on or prior to 45 days
after the Closing Date; or

               (B) notwithstanding that we have consummated or will consummate
an exchange offer, we are required to file a Shelf Registration Statement and
such Shelf Registration Statement is not filed on or prior to the date
required by the registration rights agreement, then commencing on the day
after either such required filing date, additional interest shall accrue on
the principal amount of the Outstanding Notes at a rate of 0.50% per annum for
the first 90 days immediately following each such filing date, such additional
interest rate increasing by an additional 0.50% per annum at the beginning of
each subsequent 90- day period; or

         (2)    if:

                (A) neither the exchange offer registration statement nor a
Shelf Registration Statement is declared effective by the Commission on or
prior to 150 days after the Closing Date; or

                (B) notwithstanding that we have consummated or will consummate
an exchange offer, we are required to file a Shelf Registration Statement and
such Shelf Registration Statement is not declared effective by the Commission
on or prior to the 60th day following the date such Shelf Registration
Statement was filed, then, commencing on the day after either such required
effective date, additional interest shall accrue on the principal amount of
the Outstanding Notes at a rate of 0.50% per annum for the first 90 days
immediately following such date, such additional interest rate increasing by
an additional 0.50% per annum at the beginning of each subsequent 90-day
period; or

         (3)     if:

                (A) we have not exchanged exchange notes for all Outstanding
Notes validly tendered in accordance with the terms of the exchange offer on or
prior to the 30th day after the date on which the exchange offer registration
statement was declared effective; or

                (B) if applicable, the Shelf Registration Statement has been
declared effective and such Shelf Registration Statement ceases to be
effective at any time prior to the second anniversary of its effective date
(other than after such time as all Outstanding Notes have been disposed of
thereunder),

then additional interest shall accrue on the principal amount of the
Outstanding Notes at a rate of 0.50% per annum for the first 90 days
commencing on:

                    (x) the 31st day after such effective date, in the case of
(A) above; or

                    (y) the day such Shelf Registration Statement ceases to be
effective, in the case of (B) above, such additional interest rate increasing
by an additional 0.50% per annum at the beginning of each subsequent 90-day
period; provided, however, that the additional interest rate on the notes may
not exceed in the aggregate 2.0% per annum; provided, further, however, that:


                                      38


<PAGE>




                    (a) upon the filing of the exchange offer registration
statement or a Shelf Registration Statement (in the case of clause (1) above);

                    (b) upon the effectiveness of the exchange offer
registration statement or a shelf registration (in the case of clause (2)
above); or

                    (c) upon the exchange of exchange notes for all Outstanding
Notes tendered (in the case of clause (3) (A) above), or upon the effectiveness
of the Shelf Registration Statement which had ceased to remain effective (in the
case of clause (3)(B) above), additional interest on the Outstanding Notes
as a result of such clause (or the relevant subclause thereof), as the case
may be, shall cease to accrue.

          If the Company and the Guarantors effect the exchange offer, the
Company will be entitled to close the exchange offer 20 business days after
the commencement thereof, provided that it has accepted all Outstanding Notes
theretofore validly surrendered in accordance with the terms of the exchange
offer. Outstanding Notes not tendered in the exchange offer shall bear
interest at the rate set forth on the cover page of this Prospectus and be
subject to all of the terms and conditions specified in the Indenture and to
the transfer restrictions described in the Transfer Restrictions section of
the Offering Memorandum, dated December 16, 1999.

Guarantee

          The Company's obligations under the Notes are fully and
unconditionally guaranteed on an unsecured, unsubordinated basis, jointly and
severally, by the Guarantors; so long as no Note Guarantee is enforceable
against any Guarantor in an amount in excess of the net worth of such
Guarantor at the time that determination of that net worth is, under
applicable law, relevant to the enforceability of such Note Guarantee. The net
worth will include any claim of the Guarantor against the Company for
reimbursement and any claim against any other Guarantor for contribution.

          Each Note Guarantee, other than the Note Guarantee provided by ATA,
will provide by its terms that it will be automatically and unconditionally
released and discharged if any sale, exchange or transfer to any Person that
is not an Affiliate of the Company, of all of the Company's and each
Restricted Subsidiary's Capital Stock issued by, or all or substantially all
the assets of, the Guarantor (which sale, exchange or transfer is not
prohibited by the Indenture).

Ranking

          The indebtedness evidenced by the Notes and the Note Guarantees will
rank equally in right of payment with all existing and future unsubordinated
indebtedness of the Company and the Guarantors, respectively, and senior in
right of payment to all existing and future subordinated indebtedness of the
Company and the Guarantors, respectively. The Notes and Note Guarantees will
also be effectively subordinated to all existing and future secured
indebtedness of the Company and the Guarantors, to the extent of such
security.

          At September 30, 1999, after giving pro forma effect to the private
placement and the application of the net proceeds thereof, the Company (on a
consolidated basis) would have had outstanding approximately $359.4 million of
indebtedness (including the Notes), approximately $55.0 million of which would
have been secured. At September 30, 1999, after giving pro forma effect to the
Offering and the application of the net proceeds thereof, the Guarantors (on a
consolidated basis excluding indebtedness owed to the Company and indebtedness
of Amtran) would have had approximately $359.4 million of indebtedness
outstanding (other than the Note Guarantees, approximately $55.0 million of
which would have been secured indebtedness. See "Capitalization."

          The Credit Agreement is secured by certain L-1011 aircraft and
related engines, including spares, and may be secured by other assets as
provided thereunder. See "Description of Other Indebtedness." The Notes will
be effectively subordinated to such indebtedness to the extent of such
security interests. See "Risk Factors--Effective Subordination of Notes to
Secured Obligations of Subsidiaries."

          subsequent transfer of such Indebtedness (other than to the Company
          or another Restricted Subsidiary) shall be deemed, in each case, to

                    may be;

                    (B) in case the Indebtedness to be refinanced is

          prior to the Closing Date shall be treated as Incurred pursuant to

          Indebtedness" covenant;

               (ii) Guarantees, Liens or obligations with respect to letters
          of credit supporting Indebtedness otherwise included in the
          determination of such particular amount shall not be included; and

               (iii) any Liens granted pursuant to the equal and ratable
          provisions referred to in the "Limitation on Liens" covenant
          described below shall not be treated as Indebtedness.

          For purposes of determining compliance with this "Limitation on
Indebtedness" covenant, in the event that an item of Indebtedness meets the
criteria of more than one of the types of Indebtedness described in the above
clauses (other than Indebtedness referred to in clause (1) of the preceding

Company, in its sole discretion shall classify such item of Indebtedness
and only be required to include the amount and type of such Indebtedness in
one of such clauses.

          (other than a Wholly Owned Restricted Subsidiary) or any Holder (or
          any Affiliate of such Holder) of 5% or more of the Capital Stock of
          the Company;

               (iii) make any voluntary or optional principal payment, or

          at the time of, and after giving effect to, the proposed Restricted
          Payment:

                         (A) a Default or Event of Default shall have occurred
and be continuing;

                         (B) the Company could not Incur at least $1.00 of

                         (C) the aggregate amount of all Restricted Payments
(the amount, if other than in cash, to be determined in good faith by the Board
of Directors, whose determination shall be conclusive and evidenced by a Board
Resolution) made after the Closing Date shall exceed the sum of

                         (1) 50% of the aggregate amount of the Adjusted
                    Consolidated Net Income (or, if the Adjusted Consolidated
                    Net Income is a loss, minus 100% of the amount of such
                    loss) (determined by excluding income resulting from
                    transfers of assets by the Company or a Restricted
                    Subsidiary to an Unrestricted Subsidiary) accrued on a
                    cumulative basis during the period (taken as one

                    ending on the last day of the last fiscal quarter
                    preceding the Transaction Date for which reports have been
                    filed with the Commission or provided to the Trustee
                    pursuant to the "Commission Reports and Reports to
                    Holders" covenant; plus

                         (2) the aggregate Net Cash Proceeds received by the
                    Company after the Closing Date from the issuance and sale
                    permitted by the Indenture of its Capital Stock (other
                    than Disqualified Stock) to a Person who is not a
                    Subsidiary of the Company, including an issuance or sale
                    permitted by the Indenture of Indebtedness of the Company
                    for cash subsequent to the Closing Date upon the
                    conversion of such Indebtedness into Capital Stock (other
                    than Disqualified Stock) of the Company, or from the
                    issuance to a Person who is not a Subsidiary of the
                    Company of any options, warrants or other rights to
                    acquire Capital Stock of the Company (in each case,
                    exclusive of any Disqualified Stock or any options,
                    warrants or other rights that are redeemable at the option
                    of the Holder, or are required to be redeemed, prior to
                    the Stated Maturity of the Notes); plus

                         (3) an amount equal to the net reduction in
                    Investments (other than reductions in Permitted
                    Investments) in any Person resulting from payments of
                    interest on Indebtedness, dividends, repayments of loans
                    or advances, or other transfers of assets, in each case to
                    the Company or any Restricted Subsidiary or from the Net
                    Cash Proceeds from the sale of any such Investment
                    (except, in each case, to the extent any such payment or
                    proceeds are included in the calculation of Adjusted
                    Consolidated Net Income), or from redesignations of
                    Unrestricted Subsidiaries as Restricted Subsidiaries
                    (valued in each case as provided in the definition of
                    "Investments"); not to exceed, in each case, the amount of
                    Investments previously made by the Company or any
                    Restricted Subsidiary in such Person or Unrestricted
                    Subsidiary; minus

                         (4) the sum of the amounts by which the Pro Forma
                    Consolidated Net Worth after giving effect to each
                    consolidation, merger and sale of assets effectuated
                    pursuant to clause (iii) under the "Consolidation, Merger
                    and Sale of Assets" covenant was less than the Base
                    Consolidated Net Worth immediately prior to such
                    consolidation, merger and sale of assets; plus

                         (5) $5 million.

The foregoing provision shall not be violated by reason of:

               (i) the payment of any dividend within 60 days after the date
          of declaration thereof if, at said date of declaration, such payment
          would comply with the foregoing paragraph;

               (ii) the redemption, repurchase, defeasance or other
          acquisition or retirement for value of Indebtedness that is
          subordinated in right of payment to the Notes including premium, if
          any and accrued and unpaid interest, with the proceeds of, or in
          exchange for, Indebtedness Incurred under clause (iii) of the second
          paragraph of part (a) of the "Limitation on Indebtedness" covenant;

               (iii) the repurchase, redemption or other acquisition of
          Capital Stock of the Company or an Unrestricted Subsidiary (or
          options, warrants or other rights to acquire such Capital Stock) in
          exchange for, or out of the proceeds of a substantially concurrent
          offering of, shares of Capital Stock (other than Disqualified Stock)
          of the Company (or options, warrants or other rights to acquire such
          Capital Stock);

               (iv) the making of any principal payment or the repurchase,
          redemption, retirement, defeasance or other acquisition for value of
          Indebtedness of the Company or any Guarantor which is subordinated
          in right of payment to the Notes or the Note Guarantees, as the case
          may be, in exchange for, or out of the proceeds of, a substantially
          concurrent offering of, shares of the Capital Stock (other than
          Disqualified Stock) of the Company or any Guarantor (or options,
          warrants or other rights to acquire such Capital Stock);

               (v) payments or distributions, to dissenting stockholders
          pursuant to applicable law, pursuant to or in connection with a
          consolidation, merger or transfer of assets that complies with the
          provisions of the Indenture applicable to mergers, consolidations
          and transfers of all or substantially all of the property and assets
          of the Company;

               (vi) Investments acquired in exchange for Capital Stock (other
          than Disqualified Stock) of the Company; provided that, except in
          the case of clauses (i) and (iii), no Default or Event of Default
          shall have occurred and be continuing or occur as a consequence of
          the actions or payments set forth therein; or

               (vii) the purchase or redemption of subordinated Indebtedness
          pursuant to asset sale or change of control provisions contained in
          the Indenture or other governing instrument relating thereto;
          provided, however, that (a) no offer or purchase obligation may be
          triggered in respect of such Indebtedness unless a corresponding
          obligation also arises for the Notes and (b) in all events, no
          repurchase or redemption of such Indebtedness may be consummated
          unless and until the Company shall have satisfied all repurchase
          obligations with respect to any required purchase offer made with
          respect to the Notes.

          Each Restricted Payment permitted pursuant to the preceding
paragraph (other than the Restricted Payment referred to in clause (ii)
thereof, an exchange of Capital Stock for Capital Stock or Indebtedness
referred to in clause (iii) or (iv) thereof and an Investment referred to in
clause (vi) thereof), and the Net Cash Proceeds from any issuance of Capital
Stock referred to in clauses (iii) and (iv), shall be included in calculating
whether the conditions of clause (C) of the first paragraph of this
"Limitation on Restricted Payments" covenant have been met with respect to any
subsequent Restricted Payments. In the event the proceeds of an issuance of
Capital Stock of the Company are used for the redemption, repurchase or other
acquisition of the Notes, or Indebtedness that is pari passu with the Notes,
then the Net Cash Proceeds of such issuance shall be included in clause (C) of
the first paragraph of this "Limitation on Restricted Payments" covenant only
to the extent such proceeds are not used for such redemption, repurchase or
other acquisition of Indebtedness.

Limitation on Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries

          The Company will not, and will not permit any Restricted Subsidiary
to, create or otherwise cause or suffer to exist or become effective any
consensual encumbrance or restriction of any kind on the ability of any
Restricted Subsidiary that is not a Guarantor to:

               (i) pay dividends or make any other distributions permitted by
          applicable law on any Capital Stock of such Restricted Subsidiary
          owned by the Company or any other Restricted Subsidiary;

               (ii) pay any Indebtedness owed to the Company or any other
          Restricted Subsidiary;

               (iii) make loans or advances to the Company or any other
          Restricted Subsidiary; or

               (iv) transfer any of its property or assets to the Company or
          any other Restricted Subsidiary.

          The foregoing provisions shall not restrict any encumbrances or
restrictions:

               (i) existing on the Closing Date in the Credit Agreement, the
          Indenture or any other agreements in effect on the Closing Date, and
          any extensions, refinancings, renewals or replacements of such
          agreements; provided that the encumbrances and restrictions in any
          such extensions, refinancings, renewals or replacements are no less
          favorable in any material respect to the Holders than those
          encumbrances or restrictions that are then in effect and that are
          being extended, refinanced, renewed or replaced;

               (ii) existing under or by reason of applicable law;

               (iii) existing with respect to any Person or the property or
          assets of such Person acquired by the Company or any Restricted
          Subsidiary, existing at the time of such acquisition and not
          incurred in contemplation thereof, which encumbrances or
          restrictions are not applicable to any Person or the property or
          assets of any Person other than such Person or the property or
          assets of such Person so acquired;

               (iv) in the case of clause (iv) of the first paragraph of this
          "Limitation on Dividend and Other Payment Restrictions Affecting
          Restricted Subsidiaries" covenant, (A) that restrict in a customary
          manner the subletting, assignment or transfer of any property or
          asset that is a lease, license, conveyance or contract or similar
          property or asset, (B) existing by virtue of any transfer of,
          agreement to transfer, option or right with respect to, or Lien on,
          any property or assets of the Company or any Restricted Subsidiary
          not otherwise prohibited by the Indenture or (C) arising or agreed
          to in the ordinary course of business, not relating to any
          Indebtedness, and that do not, individually or in the aggregate,
          detract from the value of property or assets of the Company or any
          Restricted Subsidiary in any manner material to the Company or any
          Restricted Subsidiary;

               (v) with respect to a Restricted Subsidiary and imposed
          pursuant to an agreement that has been entered into for the sale or
          disposition of all or substantially all of the Capital Stock of, or
          property and assets of, such Restricted Subsidiary; or

               (vi) contained in the terms of any Indebtedness or any
          agreement pursuant to which such Indebtedness was issued if:


                                      56


<PAGE>


                            (A) the encumbrance or restriction applies only
         in the event of a payment default or a default with respect to a
         financial covenant contained in such Indebtedness or agreement;

                          (B) the encumbrance or restriction is not
         materially more disadvantageous to the Holders of the Notes than
         is customary in comparable financings (as determined by the
         Company); and

                          (C) the Company determines that any such
         encumbrance or restriction will not materially affect the
         Company's ability to make principal or interest payments on the
         Notes. Nothing contained in this "Limitation on Dividend and Other
         Payment Restrictions Affecting Restricted Subsidiaries" covenant
         shall prevent the Company or any Restricted Subsidiary from:

                         (1) creating, incurring, assuming or suffering to
                    exist any Liens otherwise permitted in the "Limitation on
                    Liens" covenant; or

                         (2) restricting the sale or other disposition of
                    property or assets of the Company or any of its Restricted
                    Subsidiaries that secure Indebtedness of the Company or
                    any of its Restricted Subsidiaries.

Limitation on the Issuance and Sale of Capital Stock of Restricted Subsidiaries

          The Company will not sell, and will not permit any Restricted
Subsidiary, directly or indirectly, to issue or sell, any shares of Capital
Stock of a Restricted Subsidiary (including options, warrants or other rights
to purchase shares of such Capital Stock) except:

                    (i) to the Company or a Wholly Owned Restricted
               Subsidiary;

                    (ii) issuances of director's qualifying shares or sales to
               foreign nationals of shares of Capital Stock of foreign
               Restricted Subsidiaries, to the extent required by applicable
               law; or

                    (iii) if, immediately after giving effect to such issuance
               or sale, such Restricted Subsidiary would no longer constitute
               a Restricted Subsidiary and any Investment in such Person
               remaining after giving effect to such issuance or sale would
               have been permitted to be made under the "Limitation on
               Restricted Payments" covenant if made on the date of such
               issuance or sale.

Limitation on Issuances of Guarantees by Restricted Subsidiaries

          The Company will not permit any Restricted Subsidiary that is not a
Guarantor, directly or indirectly, to Guarantee any Indebtedness of the
Company which is pari passu with or subordinate in right of payment to the
Notes ("Guaranteed Indebtedness"), unless:

                    (i) such Restricted Subsidiary simultaneously executes and
               delivers a supplemental indenture to the Indenture providing
               for a Guarantee (a "Subsidiary Guarantee") of payment of the
               Notes by such Restricted Subsidiary; and

                    (ii) such Restricted Subsidiary waives and will not in any
               manner whatsoever claim or take the benefit or advantage of,
               any rights of reimbursement, indemnity or subrogation or any
               other rights against the Company or any other Restricted
               Subsidiary as a result of any payment by such Restricted
               Subsidiary under its Subsidiary Guarantee; provided that this
               paragraph shall not be applicable to any Guarantee of any
               Restricted Subsidiary that existed at the time such Person
               became a Restricted Subsidiary and was not Incurred in
               connection with, or in contemplation of, such Person becoming a
               Restricted Subsidiary. If the Guaranteed Indebtedness is:

                           (A) pari passu with the Notes or the Note
                  Guarantees, then the Guarantee of such Guaranteed
                  Indebtedness shall be pari passu with, or subordinated
                  to, the Subsidiary Guarantee or

                           (B) subordinated to the Notes or the Note
                  Guarantees, then the Guarantee of such Guaranteed
                  Indebtedness shall be subordinated to the Subsidiary
                  Guarantee at least to the extent that the Guaranteed
                  Indebtedness is subordinated to the Notes or the Note
                  Guarantees, as the case may be.


                                      57


<PAGE>


          Notwithstanding the foregoing, any Subsidiary Guarantee by a
Restricted Subsidiary may provide by its terms that it shall be automatically
and unconditionally released and discharged upon

                    (i) any sale, exchange or transfer, to any Person not an
               Affiliate of the Company, of all of the Company's and each
               Restricted Subsidiary's Capital Stock in, or all or
               substantially all the assets of, such Restricted Subsidiary
               (which sale, exchange or transfer is not prohibited by the
               Indenture) or

                    (ii) the release or discharge of the Guarantee which
               resulted in the creation of such Subsidiary Guarantee, except a
               discharge or release by or as a result of payment under such
               Guarantee.

Limitation on Transactions with Shareholders and Affiliates

          The Company will not, and will not permit any Restricted Subsidiary
to, directly or indirectly, enter into, renew or extend any transaction
(including, without limitation, the purchase, sale, lease or exchange of
property or assets, or the rendering of any service) with any Holder (or any
Affiliate of such Holder) of 5% or more of any class of Capital Stock of the
Company or with any Affiliate of the Company or any Restricted Subsidiary,
except upon fair and reasonable terms no less favorable to the Company or such
Restricted Subsidiary than could be obtained, at the time of such transaction
or, if such transaction is pursuant to a written agreement, at the time of the
execution of the agreement providing therefor, in a comparable arm's-length
transaction with a Person that is not such a Holder or an Affiliate.

          The foregoing limitation does not limit, and shall not apply to:

                    (i) transactions (A) approved by a majority of the
               disinterested members of the Board of Directors, or (B) for
               which the Company or a Restricted Subsidiary delivers to the
               Trustee a written opinion of a nationally recognized investment
               banking firm stating that the transaction is fair to the
               Company or such Restricted Subsidiary from a financial point of
               view;

                    (ii) any transaction solely between the Company and any of
               its Wholly Owned Restricted Subsidiaries or solely between
               Wholly Owned Restricted Subsidiaries;

                    (iii) the payment of reasonable and customary regular
               compensation (whether in cash or securities) and expense
               reimbursements to directors of the Company who are not
               employees of the Company;

                    (iv) any payments or other transactions pursuant to any
               tax-sharing agreement between the Company and any other Person
               with which the Company files a consolidated tax return or with
               which the Company is part of a consolidated group for tax
               purposes; or

                    (v) any Restricted Payments not prohibited by the
               "Limitation on Restricted Payments" covenant. Notwithstanding
               the foregoing, any transaction or series of related
               transactions covered by the first paragraph of this "Limitation
               on Transactions with Shareholders and Affiliates" covenant and
               not covered by clauses (ii) through (v) of this paragraph;

          (a) the aggregate amount of which exceeds $1 million in value, must
be approved or determined to be fair in the manner provided for in clause
(i)(A) or (B) above; and

          (b) the aggregate amount of which exceeds $3 million in value, must
be determined to be fair in the manner provided for in clause (i)(B) above.

Limitation on Liens

          The Company will not, and will not permit any Restricted Subsidiary
to, create, incur, assume or suffer to exist any Lien on any of its assets or
properties of any character, or any shares of Capital Stock or Indebtedness of
any Restricted Subsidiary, without making effective provision for all of the
Notes (or in the case of a Lien on assets or properties of a Guarantor, the
Note Guarantee of such Guarantor) and all other amounts due under the
Indenture to be directly secured equally and ratably with (or, if the
obligation or liability to be secured by such Lien is subordinated in right of
payment to the Notes or the Note Guarantee, prior to) the obligation or
liability secured by such Lien.


                                      58


<PAGE>


          The foregoing limitation does not apply to:

               (i) Liens existing on the Closing Date, including Liens
          securing obligations under the Credit Agreement;

               (ii) Liens granted after the Closing Date on any assets or
          Capital Stock of the Company or its Restricted Subsidiaries created
          in favor of the Holders;

               (iii) Liens with respect to the assets of a Restricted
          Subsidiary granted by such Restricted Subsidiary to the Company or a
          Wholly Owned Restricted Subsidiary to secure Indebtedness owing to
          the Company or such other Restricted Subsidiary;

               (iv) Liens securing Indebtedness which is Incurred to refinance
          secured Indebtedness which is permitted to be Incurred under clause
          (iii) of the second paragraph of the "Limitation on Indebtedness"
          covenant; provided that such Liens do not extend to or cover any
          property or assets of the Company or any Restricted Subsidiary other
          than the property or assets securing the Indebtedness being
          refinanced;

               (v) Liens on any property or assets of a Restricted Subsidiary
          securing Indebtedness of such Restricted Subsidiary permitted under
          the "Limitation on Indebtedness" covenant; or

               (vi) Permitted Liens.

Limitation on Sale-Leaseback Transactions

          The Company will not, and will not permit any Restricted Subsidiary
to, enter into any sale-leaseback transaction involving any of its assets or
properties whether now owned or hereafter acquired, whereby the Company or a
Restricted Subsidiary sells or transfers such assets or properties and then or
thereafter leases such assets or properties or any part thereof or any other
assets or properties which the Company or such Restricted Subsidiary, as the
case may be, intends to use for substantially the same purpose or purposes as
the assets or properties sold or transferred.

          The foregoing restriction does not apply to any sale-leaseback
transaction if:

               (i) the lease is for a period, including renewal rights, of not
          in excess of three years;

               (ii) the lease secures or relates to industrial revenue or
          pollution control bonds;

               (iii) the transaction is solely between the Company and any
          Wholly Owned Restricted Subsidiary or solely between Wholly Owned
          Restricted Subsidiaries; or

               (iv) the Company or such Restricted Subsidiary, within 12
          months after the sale or transfer of any assets or properties is
          completed, applies an amount not less than the net proceeds received
          from such sale in accordance with clause (A) or (B) of the first
          paragraph of the "Limitation on Asset Sales" covenant described
          below.

Limitation on Asset Sales

          The Company will not, and will not permit any Restricted Subsidiary
to, consummate any Asset Sale, unless:

               (i) the consideration received by the Company or such
          Restricted Subsidiary is at least equal to the fair market value of
          the assets sold or disposed of; and

               (ii) at least 75% of the consideration received (including the
          fair market value, as determined in good faith by the Board of
          Directors, of any non-cash consideration) consists of (w) cash, (x)
          Temporary Cash Investments, (y) marketable securities which are
          liquidated for cash within 90 days following the consummation of
          such Asset Sale, and (z) the assumption of Indebtedness of the
          Company or any Restricted Subsidiary (other than the Notes and the
          Note Guarantees); provided, that:


                                      59


<PAGE>


                    (1) such Indebtedness is not subordinate in right of
               payment to the Notes and the Note Guarantees; and

                    (2) the Company or such Restricted Subsidiary is
               irrevocably released and discharged from such Indebtedness.

          In the event and to the extent that the Net Cash Proceeds received
by the Company or any of its Restricted Subsidiaries from one or more Asset
Sales occurring on or after the Closing Date in any period of 12 consecutive
months exceed 10% of Adjusted Consolidated Net Tangible Assets (determined as
of the date closest to the commencement of such 12-month period for which a
consolidated balance sheet of the Company and its Subsidiaries has been filed
with the Commission) then the Company shall or shall cause the relevant
Restricted Subsidiary to:

                   (i) within twelve months after the date Net Cash
         Proceeds so received exceed 10% of Adjusted Consolidated Net
         Tangible Assets:

                            (A) apply an amount equal to such excess Net
         Cash Proceeds to permanently repay unsubordinated Indebtedness of
         the Company, or any Restricted Subsidiary providing a Subsidiary
         Guarantee pursuant to the "Limitation on Issuances of Guarantees
         by Restricted Subsidiaries" covenant described above or
         Indebtedness of any other Restricted Subsidiary, in each case
         owing to a Person other than the Company or any of its Restricted
         Subsidiaries; or

                           (B) invest an equal amount, or the amount not so
         applied pursuant to clause (A) (or enter into a definitive
         agreement committing to so invest within 12 months after the date
         of such agreement), in property or assets (other than current
         assets) of a nature or type or that are used in a business (or in
         a company having property and assets of a nature or type, or
         engaged in a business) similar or related to the nature or type of
         the property and assets of, or the business of, the Company and
         its Restricted Subsidiaries existing on the date of such
         investment; and

                  (ii) apply (no later than the end of the 12-month period
         referred to in clause (i)) such excess Net Cash Proceeds (to the
         extent not applied pursuant to clause (i) as provided in the
         following paragraph of this "Limitation on Asset Sales" covenant.

          The amount of such excess Net Cash Proceeds required to be applied
(or to be committed to be applied) during such 12-month period as set forth in
clause (i) of the preceding sentence and not applied as so required by the end
of such period shall constitute "Excess Proceeds."

          If, as of the first day of any calendar month, the aggregate amount
of Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to
this "Limitation on Asset Sales" covenant totals at least $10 million, the
Company must commence, not later than the fifteenth Business day of such
month, and consummate an Offer to Purchase from the Holders on a pro rata
basis an aggregate principal amount of Notes equal to the Excess Proceeds on
such date, at a purchase price equal to 100% of the principal amount of the
Notes, plus, in each case, accrued interest (if any) to the Payment Date.

          In the event that more than 98% of the outstanding principal amount
of the Notes are tendered pursuant to such Offer to Purchase, the balance of
the Notes will be redeemable, at the Company's option, in whole or in part, at
any time or from time to time thereafter, at a Redemption Price equal to the
price specified in such Offer to Purchase plus accrued and unpaid interest, if
any, to the Redemption Date (subject to the right of Holders of record on the
relevant Regular Record Date that is on or prior to the Redemption Date to
receive interest due on an Interest Payment Date).

Repurchase of Notes upon a Change of Control

          The Company must commence, within 30 days of the occurrence of a
Change of Control, and consummate an Offer to Purchase for all Notes then
outstanding, at a purchase price equal to 101% of the principal amount
thereof, plus accrued interest (if any) to the Payment Date. In the event that
more than 98% of the outstanding principal amount of the Notes are tendered
pursuant to such Offer to Purchase, the balance of the Notes will be
redeemable, at the Company's option, in whole or in part, at any time or from
time to time thereafter, at a Redemption Price equal to the price specified in
such Offer to Purchase plus accrued and unpaid interest, if any, to the
Redemption Date (subject to the right of Holders of record on the relevant


                                      60


<PAGE>


Regular Record Date that is on or prior to the Redemption Date to receive
interest due on an Interest Payment Date).

          There can be no assurance that the Company will have sufficient
funds available at the time of any Change of Control to make any debt payment
(including repurchases of Notes) required by the foregoing covenant (as well
as may be contained in other securities of the Company which might be
outstanding at the time). The above covenant requiring the Company to
repurchase the Notes will, unless consents are obtained, require the Company
to repay all indebtedness then outstanding which by its terms would prohibit
such Note repurchase.

Commission Reports and Reports to Holders

          Whether or not the Company or any Guarantor is then required to file
reports with the Commission, the Company and each Guarantor shall file with
the Commission all such reports and other information as they would be
required to file with the Commission by Sections 13(a) or 15(d) under the
Exchange Act if they were subject thereto. The Company shall supply the
Trustee and each Holder or shall supply to the Trustee for forwarding to each
such Holder, without cost to such Holder, copies of such reports and other
information.

Events of Default

          The following events will be defined as "Events of Default" in the
Indenture:

               (a) default in the payment of principal of (or premium, if any,
          on) any Note when the same becomes due and payable at maturity, upon
          acceleration, redemption or otherwise;

               (b) default in the payment of interest on any Note when the
          same becomes due and payable, and such default continues for a
          period of 30 days;

               (c) default in the performance or breach of the provisions of
          the Indenture applicable to mergers, consolidations and transfers of
          all or substantially all of the assets of the Company or a Guarantor
          or the failure to make or consummate an Offer to Purchase in
          accordance with the "Limitation on Asset Sales" or "Repurchase of
          Notes upon a Change of Control" covenant;

               (d) the Company or a Guarantor defaults in the performance of
          or breaches any other covenant or agreement of the Company or a
          Guarantor in the Indenture or under the Notes (other than a default
          specified in clause (a), (b) or (c) above) and such default or
          breach continues for a period of 30 consecutive days after written
          notice by the Trustee or the Holders of 25% or more in aggregate
          principal amount of the Notes;

               (e) there occurs with respect to any issue or issues of
          Indebtedness of the Company, any Guarantor or any Significant
          Subsidiary having an outstanding principal amount of $10 million or
          more in the aggregate for all such issues of all such Persons,
          whether such Indebtedness now exists or shall hereafter be created,
          (1) an event of default that has caused the Holder thereof to
          declare such Indebtedness to be due and payable prior to its Stated
          Maturity and such Indebtedness has not been discharged in full or
          such acceleration has not been rescinded or annulled within 30 days
          of such acceleration and/or (2) the failure to make a principal
          payment at the final (but not any interim) fixed maturity and such
          defaulted payment shall not have been made, waived or extended
          within 30 days of such payment default;

               (f) any final judgment or order (not covered by insurance) for
          the payment of money in excess of $10 million in the aggregate for
          all such final judgments or orders against all such Persons
          (treating any deductibles, self-insurance or retention as not so
          covered) shall be rendered against the Company, any Guarantor or any
          Significant Subsidiary and shall not be paid or discharged, and
          there shall be any period of 30 consecutive days during which a stay
          of enforcement of such final judgment or order, by reason of a
          pending appeal or otherwise, shall not be in effect;

                  (g) a court having jurisdiction in the premises enters a
         decree or order for (A) relief in respect of the Company or any
         Significant Subsidiary in an involuntary case under any applicable
         bankruptcy, insolvency or other similar law now or hereafter in
         effect, (B) appointment of a receiver, liquidator, assignee,
         custodian, trustee, sequestrator or similar official of the
         Company or any


                                      61


<PAGE>




         Significant Subsidiary or for all or substantially all of the
         property and assets of the Company or any Significant Subsidiary
         or (C) the winding up or liquidation of the affairs of the Company
         or any Significant Subsidiary and, in each case, such decree or
         order shall remain unstayed and in effect for a period of 30
         consecutive days;

               (h) the Company or any Significant Subsidiary (A) commences a
          voluntary case under any applicable bankruptcy, insolvency or other
          similar law now or hereafter in effect, or consents to the entry of
          an order for relief in an involuntary case under any such law, (B)
          consents to the appointment of or taking possession by a receiver,
          liquidator, assignee, custodian, trustee, sequestrator or similar
          official of the Company or any Significant Subsidiary or for all or
          substantially all of the property and assets of the Company or any
          Significant Subsidiary or (C) effects any general assignment for the
          benefit of creditors or

               (i) any Note Guarantee ceases to be in full force and effect
          (except pursuant to its terms) or is declared null and void or any
          Guarantor denies that it has any further liability under any Note
          Guarantee, or gives notice to such effect.

          If an Event of Default (other than an Event of Default specified in
clause (g) or (h) above that occurs with respect to the Company or any
Guarantor) occurs and is continuing under the Indenture, the Trustee or the
Holders of at least 25% in aggregate principal amount of the Notes, then
outstanding, by written notice to the Company (and to the Trustee if such
notice is given by the Holders), may, and the Trustee at the request of such
Holders shall, declare the principal of, premium, if any, and accrued interest
on the Notes to be immediately due and payable.

          Upon a declaration of acceleration, such principal of, premium, if
any, and accrued interest shall be immediately due and payable. In the event
of a declaration of acceleration because an Event of Default set forth in
clause (e) above has occurred and is continuing, such declaration of
acceleration shall be automatically rescinded and annulled if the event of
default triggering such Event of Default pursuant to clause (e) shall be
remedied or cured by the Company, any Guarantor or the relevant Significant
Subsidiary or waived by the Holders of the relevant Indebtedness within 60
days after the declaration of acceleration with respect thereto. If an Event
of Default specified in clause (g) or (h) above occurs with respect to the
Company or any Significant Subsidiary, the principal of, premium, if any, and
accrued interest on the Notes then outstanding shall ipso facto become and be
immediately due and payable without any declaration or other act on the part
of the Trustee or any Holder. The Holders of at least a majority in principal
amount of the outstanding Notes by written notice to the Company and to the
Trustee, may waive all past defaults and rescind and annul a declaration of
acceleration and its consequences if:

               (i) all existing Events of Default, other than the nonpayment
          of the principal of, premium, if any, and interest on the Notes that
          have become due solely by such declaration of acceleration, have
          been cured or waived and

               (ii) the rescission would not conflict with any judgment or
          decree of a court of competent jurisdiction. For information as to
          the waiver of defaults, see "--Modification and Waiver."

          The Holders of at least a majority in aggregate principal amount of
the outstanding Notes may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee. However, the Trustee may refuse to follow any
direction that conflicts with law or the Indenture, that may involve the
Trustee in personal liability, or that the Trustee determines in good faith
may be unduly prejudicial to the rights of Holders of Notes not joining in the
giving of such direction and may take any other action it deems proper that is
not inconsistent with any such direction received from Holders of Notes. A
Holder may not pursue any remedy with respect to the Indenture or the Notes
unless:

               (i) the Holder gives the Trustee written notice of a continuing
          Event of Default;

               (ii) the Holders of at least 25% in aggregate principal amount
          of outstanding Notes make a written request to the Trustee to pursue
          the remedy;

               (iii) such Holder or Holders offer the Trustee indemnity
          satisfactory to the Trustee against any costs, liability or expense;


                                      62


<PAGE>


               (iv) the Trustee does not comply with the request within 60
          days after receipt of the request and the offer of indemnity; and

               (v) during such 60-day period, the Holders of a majority in
          aggregate principal amount of the outstanding Notes do not give the
          Trustee a direction that is inconsistent with the request. However,
          such limitations do not apply to the right of any Holder of a Note
          to receive payment of the principal of, premium, if any, or interest
          on, such Note or to bring suit for the enforcement of any such
          payment, on or after the due date expressed in the Notes, which
          right shall not be impaired or affected without the consent of the
          Holder.

          The Indenture will require certain officers of the Company and each
Guarantor to deliver to the Trustee on or before a date not more than 90 days
after the end of each fiscal year, an Officers' Certificate stating whether or
not such officers know of any Default or Event of Default that occurred during
such fiscal year. The Company and each Guarantor will also be obligated to
notify the Trustee of any default or defaults in the performance of any
covenants or agreements under the Indenture.

Consolidation, Merger and Sale of Assets

          Neither the Company nor any Guarantor will consolidate with, merge
with or into, or sell, convey, transfer, lease or otherwise dispose of all or
substantially all of its property and assets (as an entirety or substantially
an entirety in one transaction or a series of related transactions) to, any
Person or permit any Person to merge with or into the Company or any Guarantor
unless:

               (i) the Company or the Guarantor shall be the continuing
          Person, or the Person (if other than the Company or the Guarantor)
          formed by such consolidation or into which the Company or the
          Guarantor is merged or that acquired or leased such property and
          assets of the Company or the Guarantor shall be a corporation
          organized and validly existing under the laws of the United States
          of America or any jurisdiction thereof and shall expressly assume,
          by a supplemental indenture, executed and delivered to the Trustee,
          all of the obligations of the Company or the Guarantor, as the case
          may be, on all of the Notes or the Note Guarantees, as the case may
          be, and under the Indenture;

               (ii) immediately after giving effect to such transaction, no
          Default or Event of Default shall have occurred and be continuing;

               (iii) immediately after giving effect to such transaction on a
          pro forma basis, the Company or any Guarantor, as the case may be,
          or any Person becoming the successor obligor of the Notes or the
          Note Guarantees, as the case may be, shall have a Consolidated Net
          Worth (a "Pro Forma Consolidated Net Worth") which is equal to or
          greater than the Consolidated Net Worth of the Company or the
          Guarantor, as the case may be, immediately prior to such transaction
          (the "Base Consolidated Net Worth"), or if the Pro Forma
          Consolidated Net Worth is less than the Base Consolidated Net Worth,
          the amount by which the Pro Forma Consolidated Net Worth is less
          than the Base Consolidated Net Worth shall, if considered as a
          Restricted Payment, be permitted to be paid at the time under the
          "Limitation on Restricted Payments" covenant;

               (iv) immediately after giving effect to such transaction on a
          pro forma basis the Company or any Guarantor, as the case may be, or
          any Person becoming the successor obligor of the Notes or the Note
          Guarantees, as the case may be, could Incur at least $1.00 of
          Indebtedness under the first paragraph of the "Limitation on
          Indebtedness" covenant; provided that this clause (iv) shall not
          apply to a consolidation or merger with or into a Wholly Owned
          Restricted Subsidiary with a positive net worth; and provided
          further that, in connection with any such merger or consolidation,
          no consideration (other than Capital Stock (other than Disqualified
          Stock) in the surviving Person, the Company or any Guarantor) shall
          be issued or distributed to the stockholders of the Company or the
          Guarantor; and

                  (v) the Company delivers to the Trustee an Officers'
         Certificate (attaching the arithmetic computations to demonstrate
         compliance with clauses (iii) and (iv)) and Opinion of Counsel, in
         each case stating that such consolidation, merger or transfer and
         such supplemental indenture complies with this provision and that
         all conditions precedent provided for herein relating to such
         transaction have been complied with; provided, however, that
         clauses (iii) and (iv) above do not apply if, in the good faith
         determination of the Board of Directors of the Company, whose
         determination shall be evidenced by a Board Resolution, the
         principal purpose of such transaction is to change the state of


                                      63


<PAGE>




         incorporation of the Company or any Guarantor; and provided
         further that any such transaction shall not have as one of its
         purposes the evasion of the foregoing limitations.

Defeasance

          Defeasance and Discharge. The Indenture provides that the Company
and each Guarantor will be deemed to have paid and will be discharged from any
and all obligations in respect of the Notes and the Note Guarantees on the
123rd day after the deposit referred to below, and the provisions of the
Indenture will no longer be in effect with respect to the Notes and the Note
Guarantees (except for, among other matters, certain obligations to register
the transfer or exchange of the Notes, to replace stolen, lost or mutilated
Notes, to maintain paying agencies and to hold monies for payment in trust)
if, among other things,

                  (A) the Company or the Guarantors have deposited with the
         Trustee, in trust, money and/or U.S. Government Obligations that
         through the payment of interest and principal in respect thereof
         in accordance with their terms will provide money in an amount
         sufficient to pay the principal of, premium, if any, and accrued
         interest on the Notes on the Stated Maturity of such payments in
         accordance with the terms of the Indenture and the Notes,

                  (B) the Company has delivered to the Trustee (i) either
         (x) an Opinion of Counsel to the effect that Holders will not
         recognize income, gain or loss for federal income tax purposes as
         a result of the Company's exercise of its option under this
         "Defeasance" provision and will be subject to federal income tax
         on the same amount and in the same manner and at the same times as
         would have been the case if such deposit, defeasance and discharge
         had not occurred, which Opinion of Counsel must be based upon (and
         accompanied by a copy of) a ruling of the Internal Revenue Service
         to the same effect unless there has been a change in applicable
         federal income tax law after the Closing Date such that a ruling
         is no longer required or (y) a ruling directed to the Trustee
         received from the Internal Revenue Service to the same effect as
         the aforementioned Opinion of Counsel and (ii) an Opinion of
         Counsel to the effect that the creation of the defeasance trust
         does not violate the Investment Company Act of 1940,

                  (C) immediately after giving effect to such deposit on a
         pro forma basis, no Event of Default, or event that after the
         giving of notice or lapse of time or both would become an Event of
         Default, shall have occurred and be continuing on the date of such
         deposit or during the period ending on the 123rd day after the
         date of such deposit, and such deposit shall not result in a
         breach or violation of, or constitute a default under, any other
         agreement or instrument to which the Company or any of its
         Subsidiaries is a party or by which the Company or any of its
         Subsidiaries is bound; and

                  (D) if at such time the Notes are listed on a national
         securities exchange, the Company has delivered to the Trustee an
         Opinion of Counsel to the effect that the Notes will not be
         delisted as a result of such deposit, defeasance and discharge.

          Defeasance of Certain Covenants and Certain Events of Default. The
Indenture further will provide that the provisions of the Indenture will no
longer be in effect with respect to clauses (iii) and (iv) under
"Consolidation, Merger and Sale of Assets" and all the covenants described
herein under "Covenants," clause (c) under "Events of Default" with respect to
such clauses (iii) and (iv) under "Consolidation, Merger and Sale of Assets,"
clause (d) with respect to such other covenants and clauses (e) and (f) under
"Events of Default" shall be deemed not to be Events of Default upon, among
other things, the deposit with the Trustee, in trust, of money and/or U.S.
Government Obligations that through the payment of interest and principal in
respect thereof in accordance with their terms will provide money in an amount
sufficient to pay the principal of, premium, if any, and accrued interest on
the Notes on the Stated Maturity of such payments in accordance with the terms
of the Indenture and the Notes, the satisfaction of the provisions described
in clauses (B)(ii), (C) and (D) of the preceding paragraph and the delivery by
the Company to the Trustee of an Opinion of Counsel to the effect that, among
other things, the Holders will not recognize income, gain or loss for federal
income tax purposes as a result of such deposit and defeasance of certain
covenants and Events of Default and will be subject to federal income tax on
the same amount and in the same manner and at the same times as would have
been the case if such deposit and defeasance had not occurred.

          Defeasance and Certain Other Events of Default. In the event the
Company exercises its option to omit compliance with certain covenants and
provisions of the Indenture with respect to the Notes as described in the
immediately preceding paragraph and the Notes are declared due and payable
because of


                                      64


<PAGE>


the occurrence of an Event of Default that remains applicable, the amount
of money and/or U.S. Government Obligations on deposit with the Trustee
will be sufficient to pay amounts due on the Notes at the time of their
Stated Maturity but may not be sufficient to pay amounts due on the Notes
at the time of the acceleration resulting from such Event of Default.
However, the Company will remain liable for such payments and the
Guarantors' Note Guarantees with respect to such payments will remain in
effect.

Modification and Waiver

          Modifications and amendments of the Indenture may be made by the
Company, the Guarantors and the Trustee with the consent of the Holders of not
less than a majority in aggregate principal amount of the outstanding Notes;
provided, however, that no such modification or amendment may, without the
consent of each Holder affected thereby,

               (i) change the Stated Maturity of the principal of, or any
          installment of interest on, any Note,

               (ii) reduce the principal amount of, or premium, if any, or
          interest on, any Note,

               (iii) change the place or currency of payment of principal of,
          or premium, if any, or interest on, any Note,

               (iv) impair the right to institute suit for the enforcement of
          any payment on or after the Stated Maturity (or, in the case of a
          redemption, on or after the Redemption Date) of any Note,

               (v) reduce the above-stated percentage of outstanding Notes the
          consent of whose Holders is necessary to modify or amend the
          Indenture,

               (vi) waive a default in the payment of principal of, premium,
          if any, or interest on the Notes,

               (vii) reduce the percentage or aggregate principal amount of
          outstanding Notes the consent of whose Holders is necessary for
          waiver of compliance with certain provisions of the Indenture or for
          waiver of certain defaults, or

               (viii) release any Guarantor from its Note Guarantee or
          otherwise modify the term the Note Guarantees in a material respect
          adverse to the Holders.

          Modifications and amendments of the Indenture may be made by the
Company, the Guarantors and the Trustee without notice to or the consent of
any Holder

               (i) to cure any ambiguity, defect or inconsistency,

               (ii) to comply with the "Consolidation, Merger and Sale of
          Assets" covenant,

               (iii) to comply with any requirements of the Commission in
          connection with the qualification of the Indenture under the Trust
          Indenture Act,

               (iv) to evidence and provide for the acceptance of appointment
          by a successor Trustee,

               (v) to provide for uncertificated Notes in addition to or in
          place of certificated Notes,

               (vi) to add one or more Subsidiary Guarantees on the terms
          required by the Indenture,

               (vii) to make any change that does not adversely affect the
          rights of any Holder in any material respect.

No Personal Liability of Incorporators, Stockholders, Officers, Directors, or
Employees

          The Indenture provides that no recourse for the payment of the
principal of, premium, if any or interest on any of the Notes or for any claim
based thereon or otherwise in respect thereof, and no recourse under or upon
any obligation, covenant or agreement of the Company or the Guarantors in the
Indenture, or in any of the Notes or because of the creation of any
Indebtedness represented thereby, shall be had against any incorporator,
stockholder, officer, director, employee or controlling person of the Company
or the


                                      65


<PAGE>




Guarantors or of any successor Person thereof. Each Holder, by accepting
the Notes, waives and releases all such liability.

Concerning the Trustee

          The Indenture provides that, except during the continuance of a
Default, the Trustee will not be liable, except for the performance of such
duties as are specifically set forth in such Indenture. If an Event of Default
has occurred and is continuing, the Trustee will use the same degree of care
and skill in its exercise as a prudent person would exercise under the
circumstances in the conduct of such person's own affairs.

          The Indenture and provisions of the Trust Indenture Act incorporated
by reference therein contain limitations on the rights of the Trustee, should
it become a creditor of the Company or a Guarantor, to obtain payment of
claims in certain cases or to realize on certain property received by it in
respect of any such claims, as security or otherwise. The Trustee is permitted
to engage in other transactions; provided, however, that if it acquires any
conflicting interest, it must eliminate such conflict or resign.

                         BOOK-ENTRY; DELIVERY AND FORM

          Exchange Notes will be represented by one or more permanent global
Notes in definitive, fully registered form without interest coupons (each a
"Global Note") and will be deposited with the Trustee as custodian for, and
registered in the name of a nominee of, DTC.

          Ownership of beneficial interests in a Global Exchange Note will be
limited to persons who have accounts with DTC ("participants") or persons who
hold interests through participants. Ownership of beneficial interests in a
Global Note will be shown on, and the transfer of that ownership will be
effected only through, records maintained by DTC or its nominee (with respect
to interests of participants) and the records of participants (with respect to
interests of persons other than participants). Beneficial Owners may hold
their interests in a Restricted Global Note directly through DTC if they are
participants in such system, or indirectly through organizations which are
participants in such system.

          So long as DTC, or its nominee, is the registered owner or Holder of
a Global Note, DTC or such nominee, as the case may be, will be considered the
sole owner or Holder of the Notes represented by such Global Note for all
purposes under the Indenture and the Notes. No beneficial owner of an interest
in a Global Note will be able to transfer that interest except in accordance
with DTC's applicable procedures, in addition to those provided for under the
Indenture.

          Payments of the principal of, and interest on, a Global Note will be
made to DTC or its nominee, as the case may be, as the registered owner
thereof. Neither the Company, the Trustee nor any Paying Agent will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in a Global Note or
for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

          The Company expects that DTC or its nominee, upon receipt of any
payment of principal or interest in respect of a Global Note, will credit
participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of such Global Note as
shown on the records of DTC or its nominee. The Company also expects that
payments by participants to owners of beneficial interests in such Global Note
held through such participants will be governed by standing instructions and
customary practices, as is now the case with securities held for the accounts
of customers registered in the names of nominees for such customers. Such
payments will be the responsibility of such participants.

          Transfers between participants in DTC will be effected in the
ordinary way in accordance with DTC rules and will be settled in same-day
funds.

          The Company expects that DTC will take any action permitted to be
taken by a Holder of Notes (including the presentation of Notes for exchange
as described below) only at the direction of one or more participants to whose
account the DTC interests in a Global Note is credited and only in respect of
such portion of the aggregate principal amount of Notes as to which such
participant or participants has or have given such direction. However, if
there is an Event of Default under the Notes, DTC will exchange the


                                      66


<PAGE>


applicable Global Note for Certificated Notes, which it will distribute to
its participants and which may be legended as set forth under the heading
"Transfer Restrictions."

          The Company understands that: DTC is a limited purpose trust company
organized under the laws of the State of New York, a "banking organization"
within the meaning of New York Banking Law, a member of the Federal Reserve
System, a "clearing corporation" within the meaning of the Uniform Commercial
Code and a "Clearing Agency" registered pursuant to the provisions of Section
17A of the Exchange Act. DTC was created to hold securities for its
participants and facilitate the clearance and settlement of securities
transactions between participants through electronic book-entry changes in
accounts of its participants, thereby eliminating the need for physical
movement of certificates and certain other organizations. Indirect access to
the DTC system is available to others such as banks, brokers, dealers and
trust companies that clear through or maintain a custodial relationship with a
participant, either directly or indirectly ("indirect participants").

          Although DTC is expected to follow the foregoing procedures in order
to facilitate transfers of interests in a Global Note among participants of
DTC, it is under no obligation to perform or continue to perform such
procedures, and such procedures may be discontinued at any time. Neither the
Company nor the Trustee will have any responsibility for the performance by
DTC or its respective participants or indirect participants of its obligations
under the rules and procedures governing its operations.

          If DTC is at any time unwilling or unable to continue as a
depositary for the Global Notes and a successor depositary is not appointed by
the Company within 90 days, the Company will issue Certificated Notes.

                CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

         The following is a general discussion of the principal U.S.
federal income tax consequences of the purchase, ownership and disposition
of the Notes to initial purchasers of Outstanding Notes who are U.S.
Holders (as defined below) and the principal U.S. federal income and estate
tax consequences of the purchase, ownership, exchange and disposition of
the Notes to initial purchasers of Outstanding Notes who are Foreign
Holders (as defined below).

          This discussion is based on currently existing provisions of the
Code, existing, temporary and proposed Treasury regulations promulgated
thereunder, and administrative and judicial interpretations thereof, all as in
effect or proposed on the date hereof and all of which are subject to change,
possibly with retroactive effect, or different interpretations. This
discussion does not address the tax consequences to subsequent purchasers of
Outstanding Notes and is limited to purchasers who hold the Notes as capital
assets, within the meaning of Section 1221 of the Code.

          This discussion also does not address the tax consequences to
Foreign Holders that are subject to U.S. federal income tax on a net basis on
income realized with respect to a Note because such income is effectively
connected with the conduct of a U.S. trade or business. Such Foreign Holders
are generally taxed in a similar manner to U.S. Holders, but certain special
rules do apply. Moreover, this discussion is for general information only and
does not address all of the tax consequences that may be relevant to
particular initial purchasers in light of their personal circumstances or to
certain types of initial purchasers (such as certain financial institutions,
insurance companies, tax-exempt entities, dealers in securities or persons who
have hedged the risk of owning a Note).

          PROSPECTIVE HOLDERS OF EXCHANGE NOTES ARE URGED TO CONSULT THEIR OWN
TAX ADVISORS AS TO THE PARTICULAR TAX CONSEQUENCES TO THEM OF THE EXCHANGE
OFFER AND THE OWNERSHIP AND DISPOSITION OF THE EXCHANGE NOTES, INCLUDING THE
APPLICABILITY OF ANY FEDERAL TAX LAWS OR ANY STATE, LOCAL OR FOREIGN TAX LAWS,
AND ANY CHANGES (OR PROPOSED CHANGES) IN APPLICABLE TAX LAWS OR
INTERPRETATIONS THEREOF.

U.S. Federal Income Taxation of U.S. Holders

          As used herein, the term "U.S. Holder" means a Holder of a Note that
is, for U.S. federal income tax purposes, (a) a citizen or resident of the
U.S., (b) a corporation, partnership or other entity created or organized in
or under the laws of the U.S. or any political subdivision thereof, (c) an
estate the income of


                                      67


<PAGE>


which is subject to U.S. federal income taxation regardless of source, or
(d) a trust subject to the primary supervision of a court within the U.S.
and the control of a U.S. fiduciary, as described in the Code.

          If a partnership holds a Note, the tax treatment of a partner will
generally depend upon the status of the partner and upon the activities of the
partnership. If you are a partner of a partnership holding a Note, we suggest
that you consult your tax advisor.

          Payment of Interest on Notes. Interest paid or payable on a Note
will be taxable to a U.S. Holder as ordinary interest income, generally at the
time it is received or accrued, in accordance with such Holder's regular
method of accounting for U.S. federal income tax purposes.

          Failure of the Company to file or cause to be declared effective an
exchange offer registration statement or Shelf Registration Statement or to
consummate the exchange offer as described under "Description of the
Notes--Registration Rights" will cause additional interest to accrue on the
Notes in the manner described therein. Such additional interest may be treated
as original issue discount, includible by a Holder in income as such interest
accrues, in advance of receipt of any cash payment thereof. The Notes will not
be issued with original issue discount.

          Sale, Exchange or Retirement of the Notes. Upon the sale, exchange,
redemption, retirement at maturity or other disposition of a Note, a U.S.
Holder generally will recognize taxable gain or loss equal to the difference
between the sum of cash plus the fair market value of all other property
received on such disposition (except to the extent such cash or property is
attributable to accrued but unpaid interest, which will be taxable as ordinary
income) and such U.S. Holder's adjusted tax basis in the Note. A U.S. Holder's
adjusted tax basis in a Note generally will equal the cost of the Note to such
U.S. Holder, less any principal payments received by such U.S. Holder.

          Gain or loss recognized on the disposition of a Note generally will
be capital gain or loss and will be long-term capital gain or loss if, at the
time of such disposition, the U.S. Holder's holding period for the Note is
more than one year.

          The exchange of a Note by a U.S. Holder for an Exchange Note should
not constitute a taxable exchange and a U.S. Holder will have the same tax
basis and holding period in the Exchange Notes as the Notes. Any increase in
the interest rate of the Notes resulting from an exchange offer not being
consummated, or a Shelf Registration Statement not being declared effective,
would not be treated as a taxable exchange.

          Backup Withholding and Information Reporting. Backup withholding and
information reporting requirements may apply to certain payments of principal,
premium, if any, and interest on a Note, and to proceeds of the sale or
redemption of a Note before maturity. The Company, its agent, a broker, the
Trustee or any paying agent, as the case may be, will be required to withhold
from any payment that is subject to backup withholding a tax equal to 31% of
such payment if a U.S. Holder fails to furnish his taxpayer identification
number (social security or employer identification number), certify that such
number is correct, certify that such Holder is not subject to backup
withholding or otherwise comply with the applicable requirements of the backup
withholding rules. Certain U.S. Holders, including all corporations, are not
subject to backup withholding and information reporting requirements. Any
amounts withheld under the backup withholding rules from a payment to a U.S.
Holder will be allowed as a credit against such U.S. Holder's U.S. federal
income tax and may entitle the Holder to a refund, provided that the required
information is furnished to the Internal Revenue Service ("IRS").

U.S. Federal Income Taxation of Foreign Holders

          As used herein, the term "Foreign Holder" means a Holder of a Note
that is, for U.S. federal income tax purposes, (a) a nonresident alien
individual, (b) a corporation organized or created under non-U.S. law, (c) an
estate that is not taxable in the U.S. on its worldwide income, or (d) a trust
that is either not subject to primary supervision over its administration by a
U.S. court or not subject to the control of a U.S. person with respect to
substantial trust decisions.

          Payment of Interest on Notes. In general, payments of interest
received by a Foreign Holder will not be subject to U.S. withholding tax if
(a) the Foreign Holder does not actually or constructively own 10% or more of
the total combined voting power of all classes of stock of the Company
entitled to vote, (b) the Foreign Holder is not a controlled foreign
corporation that is related to the Company actually or


                                      68


<PAGE>


constructively through stock ownership, (c) the Foreign Holder is not a
bank receiving interest described in Section 881(c)(3)(A) of the Code, and
(d) either (i)(I) the beneficial owner of the Note, under penalties of
perjury, provides the Company or its agents with such beneficial owner's
name and address and certifies on IRS Form W-8 (or a suitable substitute
form) that it is not a U.S. Holder or (II) a securities clearing
organization, bank or other financial institution that holds customers'
securities in the ordinary course of its trade or business (a "financial
institution") holds the Note and provides a statement to the Company or its
agent under penalties of perjury in which it certifies that such an IRS
Form W-8 (or a suitable substitute) has been received by it from the
beneficial owner of the Notes or qualifying intermediary and furnishes the
Company or its agent a copy thereof or (ii) the Foreign Holder is entitled
to the benefits of an income tax treaty under which interest on the Notes
is exempt from U.S. withholding tax and the Foreign Holder or such Foreign
Holder's agent provides a properly executed IRS Form 1001 (or a suitable
substitute) claiming the exemption. Payments of interest not exempt from
U.S. federal withholding tax as described above will be subject to such
withholding tax at the rate of 30% (subject to reduction under an
applicable income tax treaty).

          Sale, Exchange or Retirement of the Notes. A Foreign Holder
generally will not be subject to U.S. federal income tax (and generally no tax
will be withheld) with respect to gain realized on the sale, exchange,
redemption, retirement at maturity or other disposition of a Note unless (a)
the Foreign Holder is an individual who is present in the U.S. for a period or
periods aggregating 183 or more days in the taxable year of the disposition
and, generally, either has a "tax home" or an "office or other place of
business" in the U.S. or (b) the Foreign Holder is subject to tax pursuant to
the provisions of U.S. federal income tax law applicable to certain
expatriates.

          We suggest that you consult your tax advisor about the specific
methods for satisfying these requirements. These procedures will change on
January 1, 2001. In addition, a claim for exemption will not be valid if the
person receiving the applicable form has actual knowledge that the statements
on the form are false.

          Backup Withholding and Information Reporting. Backup withholding and
information reporting requirements do not apply to payments of interest made
by the Company or a paying agent to Foreign Holders if the certification
described above under "--U.S. Federal Income Taxation of Foreign
Holders--Payment of Interest on Notes" is received, provided that the payor
does not have actual knowledge that the Holder is a U.S. Holder. If any
payments of principal and interest are made to the beneficial owner of a Note
by or through the foreign office of a foreign custodian, foreign nominee or
other foreign agent of such beneficial owner, or if the foreign office of a
foreign "broker" (as defined in applicable Treasury regulations) pays the
proceeds of the sale of a Note or a coupon to the seller thereof, backup
withholding and information reporting will not apply. Information reporting
requirements (but not backup withholding) will apply, however, to a payment by
a foreign office of a broker that is a U.S. person, that derives 50% or more
of its gross income for certain periods from the conduct of a trade or
business in the U.S., or that is a "controlled foreign corporation"
(generally, a foreign corporation controlled by certain U.S. shareholders)
with respect to the United States unless the broker has documentary evidence
in its records that the Holder is a Foreign Holder and certain other
conditions are met or the Holder otherwise establishes an exemption. Payment
by a U.S. office of a broker is subject to both backup withholding at a rate
of 31% and information reporting unless the Holder certifies under penalties
of perjury that the Holder is a Foreign Holder or otherwise establishes an
exemption.

          Federal Estate Taxes. Subject to applicable estate tax treaty
provisions, Notes held at the time of death (or Notes transferred before death
but subject to certain retained rights or powers) by an individual who at the
time of death is a Foreign Holder will not be included in such Foreign
Holder's gross estate for U.S. federal estate tax purposes provided that the
individual does not actually or constructively own 10% or more of the total
combined voting power of all classes of stock of the Company entitled to vote
or hold the Notes in connection with a U.S. trade or business.

                             PLAN OF DISTRIBUTION

          A broker-dealer that is the Holder of Outstanding Notes that were
acquired for the account of such broker-dealer as a result of market-making or
other trading activities (other than Outstanding Notes acquired directly from
the Company or any affiliate of the Company) may exchange such Outstanding
Notes for Exchange Notes pursuant to the exchange offer; provided, however,
that each broker-dealer that receives Exchange Notes for its own account
pursuant to the exchange offer must acknowledge that it will deliver a


                                      69


<PAGE>


prospectus in connection with any resale of such Exchange Notes. This
prospectus, as it may be amended or supplemented from time to time, may be
used by a broker-dealer in connection with resales of Exchange Notes
received in exchange for Outstanding Notes where such Outstanding Notes
were acquired as a result of market-making activities or other trading
activities. The Company has agreed that for a period of 180 days after the
expiration date, it will make this prospectus, as amended or supplemented,
available to any broker-dealer for use in connection with any such resales.

          The Company will not receive any proceeds from any sale of Exchange
Notes by broker-dealers or any other Holder of Exchange Notes. Exchange Notes
received by broker-dealers for their own account pursuant to the exchange
offer may be sold from time to time in one or more transactions in the
over-the-counter market, in negotiated transactions, through the writing of
options on the Exchange Notes or a combination of such methods of resale, at
market prices prevailing at the time of resale, at prices related to such
prevailing market prices or negotiated prices. Any such resale may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers of any such Exchange Notes. Any
broker-dealer that resells Exchange Notes that were received by it for its own
account pursuant to the exchange offer and any broker or dealer that
participates in a distribution of such Exchange Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit on any
such resale of Exchange Notes and any commissions or concessions received by
any such persons may be deemed to be underwriting compensation under the
Securities Act. The Letter of Transmittal states that by acknowledging that it
will deliver and by delivering a prospectus, a broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the
Securities Act.

          For a period of 180 days after the expiration date the Company will
promptly send additional copies of this prospectus and any amendment or
supplement to this prospectus to any broker-dealer that requests such
documents in the Letter of Transmittal. The Company has agreed to pay all
expenses incident to the exchange offer other than commissions or concessions
of any brokers or dealers and will indemnify the Holders of the Notes
(including any broker-dealers) against certain liabilities, including
liabilities under the Securities Act.

Item 22. Undertakings.

          (a) The undersigned registrant hereby undertakes to deliver or cause
to be delivered with the prospectus, to each person to whom the prospectus is
sent or given, the latest annual report to security holders that is
incorporated by reference in the prospectus and furnished pursuant to and
meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Securities
Exchange Act of 1934; and, where interim financial information required to be
presented by Article 3 of Regulation S-X are not set forth in the prospectus,
to deliver, or cause to be delivered to each person to whom the prospectus is
sent or given,


                                      72


<PAGE>


the latest quarterly report that is specifically incorporated by reference
in the prospectus to provide such interim financial information.

     (b) Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or
otherwise, the registrant has been advised that in the opinion of the
Commission such indemnification is against public policy as expressed in
the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment
by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against
public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.

     (c) The undersigned registrant hereby undertakes to respond to
requests for information that is incorporated by reference into the
prospectus pursuant to Items 4, 10(b), 11 or 13 of this Form, within one
business day of receipt of such request, and to send the incorporated
document by first class mail or other equally prompt means. This includes
information contained in documents filed subsequent to the effective date
of the registration statement through the date of responding to the
request.

     (d) The undersigned registrant hereby undertakes to supply by means of
a post-effective amendment all information concerning a transaction, and
the company being acquired involved therein, that was not the subject of
and included in the registration statement when it became effective.

on behalf of the Company.

          If an Officer whose signature is on a Note no longer holds that office
at the time the Trustee or authenticating agent authenticates the Note, the Note
shall be valid nevertheless.

          A Note shall not be valid until the Trustee or authenticating agent
manually signs the certificate of authentication on the Note. The signature
shall be conclusive evidence that the Note has been authenticated under this
Indenture.

          At any time and from time to time after the execution of this
Indenture, the Trustee or an authenticating agent shall upon receipt of a
Company Order authenticate for original issue Notes in the aggregate principal
amount specified in such Company Order; provided that the Trustee shall be
entitled to receive an Officers' Certificate and an Opinion of Counsel of the
Company that it may reasonably request in connection with such authentication of
Notes. Such Company Order


<PAGE>


shall specify the amount of Notes to be authenticated, the date on which the
original issue of Notes is to be authenticated and the aggregate principal
amount of Notes then authorized and in case of an issuance of Notes pursuant to
Section 2.15, shall certify that such issuance is in compliance with Article
Four.

          The Trustee may appoint an authenticating agent to authenticate Notes.
If the appointment of such authenticating agent is not at the discretion and for
the convenience of the Trustee, then such authenticating agent shall be
compensated by the Company. An authenticating agent may authenticate Notes
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such authenticating
agent. An authenticating agent has the same rights as an Agent to deal with the
Company or an Affiliate of the Company.

          The Notes shall be issuable only in registered form without coupons
and only in denominations of $1,000 in principal amount and any integral
multiple thereof.

demands to or upon the Company in respect of the Notes and this Indenture may be

Company shall cause the Registrar to keep a register of the Notes and of their
transfer and exchange (the "Note Register"). The Note Register shall be in
written form or any other form capable of being converted into written form
within a reasonable time. The Company may have one or more co-Registrars and one
or more additional Paying Agents.

          The Company shall enter into an appropriate agency agreement with any
Agent not a party to this Indenture, which shall incorporate the terms of the
TIA. The agreement shall implement the provisions of this Indenture that relate
to such Agent. The Company shall give prompt written notice to the Trustee of
the name and address of any such Agent and any change in the address of such
Agent. If the Company fails to maintain a Registrar, Paying Agent and/or agent
for service of notices and demands, the Trustee shall act as such Registrar,
Paying Agent and/or agent for service of notices and demands. The Company may
remove any Agent upon written notice to such Agent and the Trustee; provided
that no such removal shall become effective until (i) the acceptance of an
appointment by a successor Agent to such Agent as evidenced by an appropriate
agency agreement entered into by the Company and such successor Agent and
delivered to the Trustee or (ii) notification to the Trustee that the Trustee
shall serve as such Agent until the appointment of a successor Agent in
accordance with clause (i) of this proviso. The Company, any Subsidiary of the
Company, or any Affiliate of any of them may act as Paying Agent, Registrar or
co-Registrar, and/or agent for service of notice and demands.

          The Company initially appoints the Trustee as Registrar, Paying Agent,
authenticating agent and agent for service of notice and demands. If, at any
time, the Trustee is not the Registrar, the Company shall furnish, or cause to
be furnished, to the Trustee at least seven Business Days before each Interest
Payment Date and at such other times as the Trustee may reasonably request, the
names and addresses of the Holders as they appear in the Note Register. At the
option of the Company, payment of interest may be made by check mailed to the
address of the Holders as such address appears in the Note Register.

          SECTION 2.05. Paying Agent to Hold Money in Trust. Not later than each
due date of the principal, premium, if any, and interest on any Notes, the
Company shall deposit with the Paying Agent money in immediately available funds

trust for the benefit of the Holders or the Trustee all money held by the Paying
Agent for the payment of principal of, premium, if any, and interest on the
Notes (whether such money has been paid to it by the Company or any other
obligor on the Notes), and such Paying Agent shall promptly notify the Trustee
of any default by the Company (or any other obligor on the Notes) in making any
such payment. The Company at any time may require a Paying Agent to pay all
money held by it to the Trustee and account for any funds disbursed, and the
Trustee may at any time during the continuance of any payment default, upon
written request to a Paying Agent, require such Paying Agent to pay all money
held by it to the Trustee and to account for any funds disbursed. Upon doing so,
the Paying Agent shall have no further liability for the money so paid over to
the Trustee. If the Company or any Subsidiary of the Company or any Affiliate of
any of them acts as Paying Agent, it will, on or before each due date of any
principal of, premium, if any, or interest on the Notes, segregate and hold in a
separate trust fund for the benefit of the Holders a sum of money sufficient to
pay such principal, premium, if any, or interest so becoming due until such sum
of money shall be paid to such Holders or otherwise disposed of as provided in
this Indenture, and will promptly notify the Trustee of its action or failure to
act.

          SECTION 2.06. Transfer and Exchange. The Notes are issuable only in
registered form. A Holder may transfer a Note by written application to the
Registrar stating the name of the proposed transferee and otherwise complying
with the terms of this Indenture. No such transfer shall be effected until, and
such transferee shall succeed to the rights of a Holder only upon, final
acceptance and registration of the transfer by the Registrar in the Note
Register. Prior to the registration of any transfer by a Holder as provided
herein, the Company, the Guarantors, the Trustee, and any agent of the Company,
the Guarantors or the Trustee shall treat the person in whose name the Note is
registered as the owner thereof for all purposes whether or not the Note shall
be overdue, and neither the Company, the Trustee, nor any such agent shall be
affected by notice to the contrary. Furthermore, any Holder of a Global Note
shall, by acceptance of such Global Note, agree that transfers of beneficial
interests in such Global Note may be effected only through a book entry system
maintained by the Registrar for such Global Note (or its agent) and that
ownership of a beneficial interest in the Note shall be required to be reflected
in a book entry. When Notes are presented to the Registrar or a co-Registrar
with a request to register the transfer or to exchange them for an equal
principal amount of Notes of other authorized denominations (including an
exchange of Notes for Exchange Notes), the Registrar shall register the transfer
or make the exchange as requested if its requirements for such transactions are
met; provided, that no exchanges of Notes for Exchange Notes shall occur until a
Registration Statement shall have been declared effective by the Commission
(confirmed in an Officers' Certificate delivered to the Trustee) and that any
Notes that are exchanged for Exchange Notes shall be cancelled by the Trustee.
To permit registrations of transfers and exchanges, the Company shall execute
and the Trustee shall authenticate Notes at the Registrar's request. No service
charge shall be made for any registration of transfer or exchange or redemption
of the Notes, but the Company may require payment of a sum sufficient to cover
any transfer tax or similar governmental charge payable in connection therewith
(other than any such transfer taxes or other similar governmental charge payable
upon exchanges pursuant to Section 2.11, 3.08 or 9.04).

          The Registrar shall not be required (i) to issue, register the
transfer of or exchange any Note during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Notes selected for redemption under Section 3.03 and ending at the close of
business on the day of such mailing, or (ii) to register the transfer of or
exchange any Note so selected for redemption in whole or in part, except the
unredeemed portion of any Note being redeemed in part.

          SECTION 2.07. Book-Entry Provisions for Global Notes. (a) The U.S.
Global Notes and Offshore Global Notes initially shall (i) be registered in the
name of the Depositary for such Global Notes or the nominee of such Depositary,
(ii) be delivered to the Trustee as custodian for such Depositary and (iii) bear
legends as set forth in Section 2.02.

          Members of, or participants in, the Depositary (the "Agent Members")
shall have no rights under this Indenture with respect to any Global Note held
on their behalf by the Depositary, or the Trustee as its custodian, or under the
Global Note, and the Depositary may be treated by the Company, the Guarantors,
the Trustee and any agent of the Company, the Guarantors or the Trustee as the
absolute owner of such Global Note for all purposes whatsoever. Notwithstanding
the foregoing, nothing herein shall prevent the Company, the Guarantors, the
Trustee or any agent of the Company, the Guarantors or the Trustee, from giving
effect to any written certification, proxy or other authorization furnished by
the Depositary or impair, as between the Depositary and its Agent Members, the
operation of customary practices governing the exercise of the rights of a
Holder of any Note.

          (b) Transfers of a Global Note shall be limited to transfers of such
Global Note in whole, but not in part, to the Depositary, its successors or
their respective nominees. Interests of beneficial owners in a Global Note may
be transferred in accordance with the rules and procedures of the Depositary and
the provisions of Section 2.08. In addition, U.S. Physical Notes and Offshore
Physical Notes shall be transferred to all beneficial owners in exchange for
their beneficial interests in the U.S. Global Notes or the Offshore Global
Notes, respectively, if (i) the Depositary notifies the Company that it is
unwilling or unable to continue as Depositary for the U.S. Global Notes or the
Offshore Global Notes, as the case may be, and a successor depositary is not
appointed by the Company within 90 days of such notice or (ii) an Event of
Default has occurred and is continuing and the Registrar has received a request
to the foregoing effect from the Depositary.

          (c) Any beneficial interest in one of the Global Notes that is
transferred to a person who takes delivery in the form of an interest in the
other Global Note will, upon transfer, cease to be an interest in such Global
Note and become an interest in the other Global Note and, accordingly, will
thereafter be subject to all transfer restrictions, if any, and other procedures
applicable to beneficial interests in such other Global Note for as long as it
remains such an interest.

          (d) In connection with any transfer of a portion of the beneficial
interests in a U.S. Global Note or Offshore Global Note to beneficial owners
pursuant to paragraph (b) of this Section, the Registrar shall reflect on its
books and records the date and a decrease in the principal amount of the U.S.
Global Notes or Offshore Global Notes in an amount equal to the principal amount
of the beneficial interest in such Global Notes to be transferred, and the
Company shall execute, and the Trustee shall authenticate and deliver, one or
more U.S. Physical Notes or Offshore Physical Notes, as the case may be, of like
tenor and amount.

          (e) In connection with the transfer of the entire U.S. Global Note or
Offshore Global Note to beneficial owners pursuant to paragraph (b) of this
Section, the U.S. Global Note or Offshore Global Note, as the case may be, shall
be deemed to be surrendered to the Trustee for cancellation, and the Company
shall execute, and the Trustee shall authenticate and deliver, to each
beneficial owner identified by the Depositary in exchange for its beneficial
interest in the U.S. Global Note or Offshore Global Note, as the case may be, an
equal aggregate principal amount of U.S. Physical Notes or Offshore Physical
Notes, as the case may be, of authorized denominations.

          (f) Any U.S. Physical Note delivered in exchange for an interest in
the U.S. Global Note pursuant to paragraph (b), (d) or (e) of this Section
shall, except as otherwise provided


<PAGE>


by paragraph (e) of Section 2.08, bear the legend regarding transfer
restrictions applicable to the U.S. Physical Note set forth in Section 2.02.

          (g) Any Offshore Physical Note delivered in exchange for an interest
in the Offshore Global Note pursuant to paragraph (b), (d) or (e) of this
Section shall, except as otherwise provided by paragraph (e) of Section 2.08,
bear the legend regarding transfer restrictions applicable to the Offshore
Physical Note set forth in Section 2.02.

          (h) The registered holder of a Global Note may grant proxies and
otherwise authorize any person, including Agent Members and persons that may
hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Indenture or the Notes.

          (i) Beneficial owners of interests in a U.S. Global Note may receive
U.S. Physical Notes (which shall bear the Private Placement Legend if required
by Section 2.02) in accordance with the procedures of the Depositary. In
connection with the execution, authentication and delivery of such U.S. Physical
Notes, the Registrar shall reflect on its books and records a decrease in the
principal amount of the relevant U.S. Global Note equal to the principal amount
of such U.S. Physical Notes and the Company shall execute and the Trustee shall
authenticate and deliver one or more U.S. Physical Notes having an equal
aggregate principal amount.

          SECTION 2.08. Special Transfer Provisions. Unless and until a Note is
exchanged for an Exchange Note in connection with an effective Registration
Statement pursuant to the Registration Rights Agreement, the following
provisions shall apply:

          (a) Transfers to Non-QIB Institutional Accredited Investors. The
following provisions shall apply with respect to the registration of any
proposed transfer of a Note to any Institutional Accredited Investor which is
not a QIB (excluding Non-U.S. Persons):

          (i) The Registrar shall register the transfer of any Note, whether or
     not such Note bears the Private Placement Legend, if (x) the requested
     transfer is after the time period referred to in Rule 144(k) under the
     Securities Act as in effect with respect to such transfer or (y) the
     proposed transferee has delivered to the Registrar (A) a certificate
     substantially in the form of Exhibit C hereto and (B) if the aggregate
     principal amount of the Notes being transferred is less than $100,000 at
     the time of such transfer, an opinion of counsel acceptable to the Company
     that such transfer is in compliance with the Securities Act.

          (ii) If the proposed transferor is an Agent Member holding a
     beneficial interest in the U.S. Global Note, upon receipt by the Registrar
     of (x) the documents, if any, required by paragraph (i) and (y)
     instructions given in accordance with the Depositary's and the Registrar's
     procedures, the Registrar shall reflect on its books and records the date
     and a decrease in the principal amount of the U.S. Global Note in an amount
     equal to the principal amount of the beneficial interest in the U.S. Global
     Note to be transferred, and the Company shall execute, and the Trustee
     shall authenticate and deliver, one or more U.S. Physical Notes of like
     tenor and amount.

          (b) Transfers to QIBs. The following provisions shall apply with
respect to the registration of any proposed transfer of a U.S. Physical Note, an
interest in a U.S. Global Note or an interest in an Offshore Global Note prior
to the removal of the Private Placement Legend to a QIB (excluding Non-U.S.
Persons):

          (i) If the Note to be transferred consists of (x) either (A) an
     interest in a Offshore Global Note prior to the removal of the Private
     Placement Legend or (B) U.S. Physical


<PAGE>



         Notes, the Registrar shall register the transfer if such transfer is
         being made by a proposed transferor who has checked the box provided
         for on the form of Note stating, or has otherwise advised the Company
         and the Registrar in writing, that the sale has been made in compliance
         with the provisions of Rule 144A to a transferee who has signed the
         certification provided for on the form of Note stating, or has
         otherwise advised the Company and the Registrar in writing, that it is
         purchasing the Note for its own account or an account with respect to
         which it exercises sole investment discretion and that it and any such
         account is a QIB within the meaning of Rule 144A, and is aware that the
         sale to it is being made in reliance on Rule 144A and acknowledges that
         it has received such information regarding the Company as it has
         requested pursuant to Rule 144A or has determined not to request such
         information and that it is aware that the transferor is relying upon
         its foregoing representations in order to claim the exemption from
         registration provided by Rule 144A or (y) an interest in the U.S.
         Global Notes, the transfer of such interest may be effected only
         through the book entry system maintained by the Depositary.

          (ii) If the proposed transferee is an Agent Member, and the Note to be
     transferred consists of U.S. Physical Notes, upon receipt by the Registrar
     of the documents referred to in clause (i) and instructions given in
     accordance with the Depositary's and the Registrar's procedures, the
     Registrar shall reflect on its books and records the date and an increase
     in the principal amount of the U.S. Global Notes in an amount equal to the
     principal amount of the U.S. Physical Notes, to be transferred, and the
     Trustee shall cancel the U.S. Physical Notes so transferred.

          (c) Transfers of Interests in the Offshore Global Note or Offshore
Physical Notes. The following provisions shall apply with respect to any
transfer of interests in the Offshore Global Notes or Offshore Physical Notes:

          (i) prior to the removal of the Private Placement Legend from a
     Offshore Global Note or Offshore Physical Note pursuant to Section 2.02,
     the Registrar shall refuse to register such transfer unless such transfer
     complies with Section 2.08(b) or Section 2.08(d), as the case may be; and

          (ii) after such removal, the Registrar shall register the transfer of
     any such Note without requiring any additional certification.

          (d) Transfers to Non-U.S. Persons at Any Time. The following
provisions shall apply with respect to any transfer of a Note to a Non-U.S.
Person:

          (i) The Registrar shall register any proposed transfer to any Non-U.S.
     Person if the Note to be transferred is a U.S. Physical Note or an interest
     in the U.S. Global Note only upon receipt of a certificate substantially in
     the form of Exhibit D from the proposed transferor.

          (ii) (a) If the proposed Transferor is an Agent Member holding a
     beneficial interest in a U.S. Global Note, upon receipt by the Registrar of
     (x) the documents required by paragraph (i) and (y) instructions in
     accordance with the Depositary's and the Registrar's procedures, the
     Registrar shall reflect on its books and records the date and a decrease in
     the principal amount of such U.S. Global Note in an amount equal to the
     principal amount of the beneficial interest in the U.S. Global Note to be
     transferred, and (b) if the proposed transferee is an Agent Member, upon
     receipt by the Registrar of instructions given in accordance with the
     Depositary's and the Registrar's procedures, the Registrar shall reflect on
     its books and records the date and an increase in the principal amount of
     the Offshore Global Note in an


<PAGE>


     amount equal to the principal amount of the U.S. Physical Notes or the U.S.
     Global Note, as the case may be, to be transferred, and the Trustee shall
     cancel the Physical Note, if any, so transferred or decrease the amount of
     the U.S. Global Note.

          (e) Private Placement Legend. Upon the transfer, exchange or
replacement of Notes not bearing the Private Placement Legend, the Registrar
shall deliver Notes that do not bear the Private Placement Legend. Upon the
transfer, exchange or replacement of Notes bearing the Private Placement Legend,
the Registrar shall deliver only Notes that bear the Private Placement Legend
unless either (i) the circumstances contemplated by paragraphs (a)(i)(x) or
(c)(ii) of this Section 2.08 exist or (ii) there is delivered to the Registrar
an Opinion of Counsel reasonably satisfactory to the Company and the Trustee to
the effect that neither such legend nor the related restrictions on transfer are
required in order to maintain compliance with the provisions of the Securities
Act.

          (f) General. By its acceptance of any Note bearing the Private
Placement Legend, each Holder of such a Note acknowledges the restrictions on
transfer of such Note set forth in this Indenture and in the Private Placement
Legend and agrees that it will transfer such Note only as provided in this
Indenture. The Registrar shall not register a transfer of any Note unless such
transfer complies with the restrictions on transfer of such Note set forth in
this Indenture. In connection with any transfer of Notes, each Holder agrees by
its acceptance of the Notes to furnish the Registrar or the Company such
certifications, legal opinions or other information as either of them may
reasonably require to confirm that such transfer is being made pursuant to an
exemption from, or a transaction not subject to, the registration requirements
of the Securities Act; provided that the Registrar shall not be required to
determine (but may conclusively rely on a determination made by the Company with
respect to) the sufficiency of any such certifications, legal opinions or other
information.

          The Registrar shall retain copies of all letters, notices and other
written communications received pursuant to Section 2.07 or this Section 2.08.
The Company shall have the right to inspect and make copies of all such letters,
notices or other written communications at any reasonable time upon the giving
of reasonable written notice to the Registrar.

          SECTION 2.09. Replacement Notes. If a mutilated Note is surrendered to
the Trustee or if the Holder claims that the Note has been lost, destroyed or
wrongfully taken, then, in the absence of notice to the Company or the Trustee
that such Note has been acquired by a bona fide purchaser, the Company shall
issue and the Trustee shall authenticate a replacement Note of like tenor and
principal amount; provided that the requirements of this Section 2.09 are met.
If required by the Trustee or the Company, an indemnity bond must be furnished
that is sufficient in the judgment of both the Trustee and the Company to
protect the Company, the Trustee or any Agent from any loss that any of them may
suffer if a Note is replaced. The Company may charge such Holder for the
expenses of the Company and the Trustee in replacing a Note. In case any such
mutilated, lost, destroyed or wrongfully taken Note has become or is about to
become due and payable, the Company in its discretion may pay such Note instead
of issuing a new Note in replacement thereof.

          Every replacement Note is an additional obligation of the Company and
shall be entitled to the benefits of this Indenture.

          The provisions of this Section 2.09 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies against the Company and the
Trustee with respect to the replacement or payment of mutilated, destroyed, lost
or wrongfully taken Notes.


<PAGE>



          SECTION 2.10. Outstanding Notes. Notes outstanding at any time are all
Notes that have been authenticated by the Trustee except for those cancelled by
it, those delivered to it for cancellation and those described in this Section
2.10 as not outstanding.

          If a Note is replaced pursuant to Section 2.09, it ceases to be
outstanding unless and until the Trustee and the Company receive proof
satisfactory to each of them that the replaced Note is held by a bona fide
purchaser.

          If the Paying Agent (other than the Company or an Affiliate of the
Company) holds on a Redemption Date or the Stated Maturity of the Notes money
sufficient to pay Notes payable on that date, then on and after that date such
Notes cease to be outstanding and interest on them shall cease to accrue.

          Notes, or portions thereof, for the payment or redemption of which
moneys or U.S. Government Obligations (as provided for in Article Eight) in the
necessary amount shall have been deposited in trust with the Trustee or with any
Paying Agent (other than the Company) or shall have been set aside, segregated
and held in trust by the Company for the Holders of such Notes (if the Company
shall act as its own Paying Agent), on and after that time shall cease to be
outstanding and, in the case of redemption, interest on such Notes shall cease
to accrue, provided that if such Notes, or portions thereof, are to be redeemed
prior to the maturity thereof, notice of such redemption shall have been given
as herein provided, or provision satisfactory to the Trustee shall have been
made for giving such notice.

          A Note does not cease to be outstanding because the Company or one of
its Affiliates holds such Note, provided, however, that, in determining whether
the Holders of the requisite principal amount of the outstanding Notes have
given any request, demand, authorization, direction, notice, consent or waiver
hereunder, Notes owned by the Company or any other obligor upon the Notes or any
Affiliate of the Company or of such other obligor shall be disregarded and
deemed not to be outstanding, except that, in determining whether the Trustee
shall be protected in relying upon any such request, demand, authorization,
direction, notice, consent or waiver, only Notes which the Trustee has actual
knowledge to be so owned shall be so disregarded. Notes so owned which have been
pledged in good faith may be regarded as outstanding if the pledgee establishes
to the satisfaction of the Trustee the pledgee's right so to act with respect to
such Notes and that the pledgee is not the Company or any other obligor upon the
Notes or any Affiliate of the Company or of such other obligor.

          SECTION 2.11. Temporary Notes. Until definitive Notes are ready for
delivery, the Company may prepare and execute and the Trustee shall authenticate
temporary Notes. Temporary Notes shall be substantially in the form of
definitive Notes but may have insertions, substitutions, omissions and other
variations determined to be appropriate by the Officers executing the temporary
Notes, as evidenced by their execution of such temporary Notes. If temporary
Notes are issued, the Company will cause definitive Notes to be prepared without
unreasonable delay. After the preparation of definitive Notes, the temporary
Notes shall be exchangeable for definitive Notes upon surrender of the temporary
Notes at the office or agency of the Company designated for such purpose
pursuant to Section 4.02, without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Notes the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Notes of authorized denominations. Until so exchanged, the
temporary Notes shall be entitled to the same benefits under this Indenture as
definitive Notes.

          SECTION 2.12. Cancellation. The Company at any time may deliver, or
cause to be delivered, Notes to the Trustee for cancellation. The Registrar and
the Paying Agent shall


<PAGE>


forward to the Trustee any Notes surrendered to them for transfer, exchange or
payment. The Trustee (and no one else) shall cancel all Notes surrendered for
transfer, exchange, payment, replacement or cancellation and shall destroy them
in accordance with its normal procedure.

          SECTION 2.13. CUSIP Numbers. The Company in issuing the Notes may use
"CUSIP," "CINS" and "ISIN" numbers (if then generally in use), and the Trustee
shall use CUSIP, CINS or ISIN numbers, as the case may be, in notices of
redemption or exchange as a convenience to Holders; provided that any such
notice shall state that no representation is made as to the correctness of such
CUSIP, CINS or ISIN numbers either as printed on the Notes or as contained in
any notice of redemption or exchange and that reliance may be placed only on the
other identification numbers printed on the Notes; and provided further that
failure to use CUSIP, CINS or ISIN numbers in any notice of redemption or
exchange shall not affect the validity or sufficiency of such notice. The
Company shall promptly notify the Trustee of any change in CUSIP numbers.

          SECTION 2.14. Defaulted Interest. If the Company defaults in a payment
of interest on the Notes, it shall pay, or shall deposit with the Paying Agent
money in immediately available funds sufficient to pay the defaulted interest,
plus (to the extent lawful) any interest payable on the defaulted interest, to
the Persons who are Holders on a subsequent special record date. A special
record date, as used in this Section 2.14 with respect to the payment of any
defaulted interest, shall mean the 15th day next preceding the date fixed by the
Company for the payment of defaulted interest, whether or not such day is a
Business Day. At least 15 days before the subsequent special record date, the
Company shall mail to each Holder and to the Trustee a notice that states the
subsequent special record date, the payment date and the amount of defaulted
interest to be paid.

          SECTION 2.15. Issuance of Additional Notes. The Company may, subject
to Article Four of this Indenture, issue additional Notes under this Indenture.
The Notes issued on the Closing Date and any additional Notes subsequently
issued shall be treated as a single class for all purposes under this Indenture.

                                  ARTICLE THREE
                                   REDEMPTION

          SECTION 3.01. Right of Redemption. (a) The Notes will also be
redeemable, at the Company's option, in whole or in part, at any time or from
time to time, on or after August 1, 2002 and prior to maturity, upon not less
than 30 nor more than 60 days' prior notice mailed by first class mail to each
Holders' last address as it appears in the Note Register, at the following
Redemption Prices (expressed in percentages of principal amount), plus accrued
and unpaid interest, if any, to the Redemption Date (subject to the right of
Holders of record on the relevant Regular Record Date that is on or prior to the
Redemption Date to receive interest due on an Interest Payment Date), if
redeemed during the 12-month period commencing August 1 of the years set forth
below:

Redemption

                  Year

       Price

                  2002     ...................    105.250%
                  2003     ...................    102.625%


<PAGE>


          (b) In addition, at any time prior to August 1, 2000, the Company may
redeem up to 35% of the principal amount of the Notes with the proceeds of one
or more sales of its Common Stock, at any time or from time to time in part, at
a Redemption Price (expressed as a percentage of principal amount) of 110.50%,
plus accrued and unpaid interest to the Redemption Date (subject to the rights
of Holders of record on the relevant Regular Record Date that is prior to the
Redemption Date to receive interest due on an Interest Payment Date); provided
that at least $65 million aggregate principal amount of Notes remains
outstanding after each such redemption.

          (c) In the event that more than 98% of the outstanding principal
amount of the Notes are tendered pursuant to an Offer to Purchase, as required
by Section 4.11 or Section 4.12, the balance of the Notes will be redeemable, at
the Company's option, in whole or in part, at any time or from time to time
thereafter and prior to maturity, upon not less than 30 nor more than 60 days'
prior notice mailed by first class mail to each Holder's last address as it
appears in the Note Register, at a Redemption Price equal to the price specified
in such Offer to Purchase plus accrued and unpaid interest, if any, to the
Redemption Date (subject to the right of Holders of record on the relevant
Regular Record Date that is on or prior to the Redemption Date to receive
interest due on an Interest Payment Date).

          SECTION 3.02. Notices to Trustee. If the Company elects to redeem
Notes pursuant to Section 3.01(a), (b) or (c), it shall notify the Trustee in
writing of the Redemption Date, the principal amount at Stated Maturity of Notes
to be redeemed and the clause of this Indenture pursuant to which the redemption
shall occur.

          The Company shall give each notice provided for in this Section 3.02
in an Officers' Certificate at least 45 days before the Redemption Date (unless
a shorter period shall be satisfactory to the Trustee).

          SECTION 3.03. Selection of Notes to Be Redeemed. If less than all of
the Notes are to be redeemed at any time, the Trustee will select the Notes, or
portions thereof, for redemption in compliance with the requirements of the
principal national securities exchange, if any, on which the Notes are listed
or, if the Notes are not listed on a national securities exchange, by lot or by
such other method as the Trustee in its sole discretion shall deem to be fair
and appropriate; provided that no Note of $1,000 in principal amount or less
shall be redeemed in part. If any Note is to be redeemed in part only, the
notice of redemption relating to such Note shall state the portion of the
principal amount thereof to be redeemed. A new Note in principal amount equal to
the unredeemed portion thereof will be issued in the name of the Holder thereof
upon cancellation of the original Note.

          The Trustee shall make the selection from the Notes outstanding and
not previously called for redemption. Notes in denominations of $1,000 in
principal amount at Stated Maturity may only be redeemed in whole. The Trustee
may select for redemption portions (equal to $1,000 in principal amount at
Stated Maturity or any integral multiple thereof) of Notes that have
denominations larger than $1,000 in principal amount at Stated Maturity.
Provisions of this Indenture that apply to Notes called for redemption also
apply to portions of Notes called for redemption. The Trustee shall notify the
Company and the Registrar promptly in writing of the Notes or portions of Notes
to be called for redemption.

          SECTION 3.04. Notice of Redemption. With respect to any redemption of
Notes pursuant to Section 3.01(a), (b) or (c), at least 30 days but not more
than 60 days before a Redemption Date the Company shall mail or cause to be
mailed, a notice of redemption by first class mail (pursuant to the requirements
of Section 11.02) to each Holder whose Notes are to be redeemed.


<PAGE>


          The notice shall identify the Notes to be redeemed and shall state:

          (i) the Redemption Date;

          (ii) the Redemption Price;

          (iii) the name and address of the Paying Agent;

          (iv) that Notes called for redemption must be surrendered to the
     Paying Agent in order to collect the Redemption Price;

          (v) that, unless the Company defaults in making the redemption
     payment, interest on Notes called for redemption ceases to accrue on and
     after the Redemption Date and the only remaining right of the Holders is to
     receive payment of the Redemption Price plus accrued and unpaid interest to
     the Redemption Date upon surrender of the Notes to the Paying Agent;

          (vi) that, if any Note is being redeemed in part, the portion of the
     principal amount (equal to $1,000 in principal amount at Stated Maturity or
     any integral multiple thereof) of such Note to be redeemed and that, on and
     after the Redemption Date, upon surrender of such Note, a new Note or Notes
     in principal amount equal to the unredeemed portion thereof will be
     reissued;

          (vii) that, if any Note contains a CUSIP, CINS or ISIN number as
     provided in Section 2.13, no representation is being made as to the
     correctness of the CUSIP, CINS or ISIN number either as printed on the
     Notes or as contained in the notice of redemption and that reliance may be
     placed only on the other identification numbers printed on the Notes; and

          (viii) the aggregate principal amount at Stated Maturity of Notes
     being redeemed.

          At the Company's request (which request may be revoked by the Company
at any time prior to the time at which the Trustee shall have given such notice
to the Holders), made in writing to the Trustee, at least 45 days (or such
shorter period as shall be satisfactory to the Trustee) before a Redemption
Date, the Trustee shall give the notice of redemption in the name and at the
expense of the Company. If, however, the Company gives such notice to the
Holders, the Company shall concurrently deliver to the Trustee an Officers'
Certificate stating that such notice has been given.

          SECTION 3.05. Effect of Notice of Redemption. Once notice of
redemption is mailed, Notes called for redemption become due and payable on the
Redemption Date and at the Redemption Price. Upon surrender of any Notes to the
Paying Agent, such Notes shall be paid at the Redemption Price, plus accrued and
unpaid interest to the Redemption Date.

          Notice of redemption shall be deemed to be given when mailed, whether
or not the Holder receives the notice. In any event, failure to give such
notice, or any defect therein, shall not affect the validity of the proceedings
for the redemption of Notes held by Holders to whom such notice was properly
given.

          SECTION 3.06. Deposit of Redemption Price. On or prior to 10:00 a.m.
New York City time on any Redemption Date, the Company shall deposit with the
Paying Agent (or, if the Company is acting as its own Paying Agent, shall
segregate and hold in trust as provided in Section


<PAGE>


2.05) money in immediately available funds sufficient to pay the Redemption
Price of and accrued and unpaid interest on all Notes to be redeemed on that
date other than Notes or portions thereof called for redemption on that date
that have been delivered by the Company to the Trustee for cancellation.

          SECTION 3.07. Payment of Notes Called for Redemption. If notice of
redemption has been given in the manner provided above, the Notes or portion of
Notes specified in such notice to be redeemed shall become due and payable on
the Redemption Date at the Redemption Price stated therein, together with
accrued and unpaid interest to such Redemption Date, and on and after such date
(unless the Company shall default in the payment of such Notes at the Redemption
Price and accrued and unpaid interest to the Redemption Date, in which case the
principal, until paid, shall bear interest from the Redemption Date at the rate
prescribed in the Notes), such Notes shall cease to accrue interest. Upon
surrender of any Note for redemption in accordance with a notice of redemption,
such Note shall be paid and redeemed by the Company at the Redemption Price,
together with accrued and unpaid interest to the Redemption Date; provided that
installments of interest whose record date is prior to the Redemption Date shall
be payable to the Holders registered as such at the close of business such
record date, if any.

          SECTION 3.08. Notes Redeemed in Part. Upon surrender of any Note that
is redeemed in part, the Company shall at its expense issue and execute and the
Trustee shall authenticate and deliver for the Holder a new Note equal in
principal amount to the unredeemed portion of such surrendered Note.

          SECTION 4.01. Payment of Notes. The Company shall pay the principal
of, premium, if any, and interest on the Notes on the dates and in the manner
provided in the Notes and this Indenture. An installment of principal, premium,
if any, or interest shall be considered paid on the date due if the Trustee or
Paying Agent (other than the Company, a Subsidiary of the Company, or any
Affiliate of any of them) holds as of 10:00 A.M. New York City time on the due
date money deposited by the Company in immediately available funds and
designated for and sufficient to pay the installment. If the Company or any
Subsidiary of the Company or any Affiliate of any of them, acts as Paying Agent,
an installment of principal, premium, if any, or interest shall be considered
paid on the due date if the entity acting as Paying Agent complies with the last
sentence of Section 2.05. As provided in Section 6.09, upon any bankruptcy or
reorganization procedure relative to the Company, the Trustee shall serve as the
Paying Agent and conversion agent, if any, for the Notes.

          The Company shall pay interest on overdue principal, premium, if any,
and interest on overdue installments of interest, to the extent lawful, at the
rate per annum specified in the Notes.

          SECTION 4.02. Maintenance of Office or Agency. The Company will
maintain an office or agency where Notes may be surrendered for registration of
transfer or exchange or for presentation for payment and where notices and
demands to or upon the Company in respect of the Notes and this Indenture may be
served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the address of the
Trustee set forth in Section 11.02.


<PAGE>



          The Company may also from time to time designate one or more other
offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations. The
Company shall give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency.

          The Company hereby initially designates the [ ] of the Trustee as such
office of the Company in accordance with Section 2.04.

          SECTION 4.03. Limitation on Indebtedness. (a) The Company will not,
and will not permit any of its Restricted Subsidiaries to, Incur any
Indebtedness (other than the Notes, the Note Guarantees and Indebtedness
existing on the Closing Date); provided that the Company may Incur Indebtedness
if, after giving effect to the Incurrence of such Indebtedness and the receipt
and application of the proceeds therefrom, the Interest Coverage Ratio would be
greater than 3:1.

          Notwithstanding the foregoing, the Company and any Restricted
Subsidiary (except as specified below) may Incur each and all of the following:
(i) Indebtedness of the Company or any Restricted Subsidiary that is a Guarantor
outstanding at any time under the Credit Agreement; provided, that after giving
effect to the Incurrence of any such Indebtedness, the book value of assets of
the Company not subject to any Lien (other than Liens described in clauses (i)
through (v), (xiii) and (xvi) of the definition of "Permitted Liens") shall not
be less than $125 million; (ii) Indebtedness owed (A) to the Company evidenced
by an unsubordinated promissory note or (B) to any of its Restricted
Subsidiaries; provided that any event which results in any such Restricted
Subsidiary ceasing to be a Restricted Subsidiary or any subsequent transfer of
such Indebtedness (other than to the Company or another Restricted Subsidiary)
shall be deemed, in each case, to constitute an Incurrence of such Indebtedness
not permitted by this clause (ii); (iii) Indebtedness issued in exchange for, or
the net proceeds of which are used to refinance or refund, then outstanding
Indebtedness Incurred under clause (v) of this paragraph and any refinancings
thereof in an amount not to exceed the amount so refinanced or refunded (plus
premiums, accrued interest, fees and expenses); provided that Indebtedness the
proceeds of which are used to refinance or refund the Notes or Indebtedness that
is pari passu with, or subordinated in right of payment to, the Notes or Note
Guarantees shall only be permitted under this clause (iii) if (A) in case the
Notes are refinanced in part or the Indebtedness to be refinanced is pari passu
with the Notes or Note Guarantees, such new Indebtedness, by its terms or by the
terms of any agreement or instrument pursuant to which such new Indebtedness is
outstanding, is expressly made pari passu with, or subordinate in right of
payment to, the remaining Notes or Note Guarantees, as the case may be, (B) in
case the Indebtedness to be refinanced is subordinated in right of payment to
the Notes or Note Guarantees, as the case may be, such new Indebtedness, by its
terms or by the terms of any agreement or instrument pursuant to which such new
Indebtedness is issued or remains outstanding, is expressly made subordinate in
right of payment to the Notes or the Note Guarantees, as the case may be, at
least to the extent that the Indebtedness to be refinanced is subordinated to
the Notes or the Note Guarantees, as the case may be, and (C) such new
Indebtedness, determined as of the date of Incurrence of such new Indebtedness,
does not mature prior to the Stated Maturity of the Indebtedness to be
refinanced or refunded, and the Average Life of such new Indebtedness is at
least equal to the remaining Average Life of the Indebtedness to be refinanced
or refunded; and provided further that in no event may Indebtedness of the
Company be refinanced by means of any Indebtedness of any Restricted Subsidiary
pursuant to this clause (iii) (other than pursuant to an Offer to Purchase);
(iv) Indebtedness (A) in respect of performance, surety or appeal bonds provided
in the ordinary course of business, (B) under Currency Agreements and Interest
Rate Agreements; provided that such agreements (a) are designed solely to
protect the Company or its Restricted Subsidiaries against fluctuations in
foreign currency exchange rates or interest rates and (b) do not increase the
Indebtedness of the obligor outstanding at any time other than as a result of
fluctuations


<PAGE>


in foreign currency exchange rates or interest rates or by reason of fees,
indemnities and compensation payable thereunder; and (C) arising from agreements
providing for indemnification, adjustment of purchase price or similar
obligations, or from Guarantees or letters of credit, surety bonds or
performance bonds securing any obligations of the Company or any of its
Restricted Subsidiaries pursuant to such agreements, in any case Incurred in
connection with the disposition of any business, assets or Restricted Subsidiary
(other than Guarantees of Indebtedness Incurred by any Person acquiring all or
any portion of such business, assets or Restricted Subsidiary for the purpose of
financing such acquisition), in a principal amount not to exceed the gross
proceeds actually received by the Company or any Restricted Subsidiary in
connection with such disposition; (v) Indebtedness of the Company, to the extent
the net proceeds thereof are promptly (A) used to purchase Notes tendered in an
Offer to Purchase made as a result of a Change in Control or (B) deposited to
defease the Notes as described below under "Defeasance"; (vi) Guarantees of the
Notes, Guarantees by the Company or Restricted Subsidiaries of Indebtedness of
ATA under the Credit Agreement, and Guarantees of Indebtedness of the Company by
any Restricted Subsidiary provided the Guarantee of such Indebtedness is
permitted by and made in accordance with Section 4.07; (vii) Indebtedness of the
Company or any Restricted Subsidiary Incurred to finance the cost of aircraft,
engines and buyer-furnished equipment attached thereto or incorporated therein;
provided, that such Indebtedness is created solely for the purpose of financing
the costs (including transaction costs and the costs of improvement or
construction) of property or assets and is incurred prior to, at the time of or
within 12 months after, the later of the acquisition, the completion of
construction or the commencement of full operation of such property or assets,
and (b) the principal amount of such Indebtedness does not exceed 100% of such
costs; and (viii) Indebtedness of the Company (in addition to Indebtedness
permitted under clauses (i) through (vii) above) in an aggregate principal
amount outstanding at any time not to exceed $10 million.

          (b) Notwithstanding any other provision of this Section 4.03,
the maximum amount of Indebtedness that the Company or a Restricted Subsidiary
may Incur pursuant to this Section 4.03 shall not be deemed to be exceeded, with
respect to any outstanding Indebtedness due solely to the result of fluctuations
in the exchange rates of currencies.

          (c) For purposes of determining any particular amount of Indebtedness
under this Section 4.03, (1) Indebtedness Incurred under the Credit Agreement on
or prior to the Closing Date shall be treated as Incurred pursuant to clause (i)
of the second paragraph of this Section 4.03, (2) Guarantees, Liens or
obligations with respect to letters of credit supporting Indebtedness otherwise
included in the determination of such particular amount shall not be included
and (3) any Liens granted pursuant to the equal and ratable provisions referred
to in Section 4.09 shall not be treated as Indebtedness. For purposes of
determining compliance with this Section 4.03, in the event that an item of
Indebtedness meets the criteria of more than one of the types of Indebtedness
described in the above clauses (other than Indebtedness referred to in clause
(1) of the preceding sentence), the Company, in its sole discretion, shall
classify such item of Indebtedness and only be required to include the amount
and type of such Indebtedness in one of such clauses.

          SECTION 4.04. Limitation on Restricted Payments. The Company will not,
and will not permit any Restricted Subsidiary to, directly or indirectly, (i)
declare or pay any dividend or make any distribution on or with respect to its
Capital Stock (other than (x) dividends or distributions payable solely in
shares of its Capital Stock (other than Disqualified Stock) or in options,
warrants or other rights to acquire shares of such Capital Stock and (y) pro
rata dividends or distributions on Common Stock of Restricted Subsidiaries held
by minority stockholders) held by Persons other than the Company or any of its
Restricted Subsidiaries, (ii) purchase, redeem, retire or otherwise acquire for
value any shares of Capital Stock of (A) the Company or an Unrestricted
Subsidiary (including options, warrants or other rights to acquire such shares
of Capital Stock) held by any Person or (B) a Restricted Subsidiary (including
options, warrants or other rights to acquire


<PAGE>


such shares of Capital Stock) held by any Affiliate of the Company (other than a
Wholly Owned Restricted Subsidiary) or any holder (or any Affiliate of such
holder) of 5% or more of the Capital Stock of the Company, (iii) make any
voluntary or optional principal payment, or voluntary or optional redemption,
repurchase, defeasance, or other acquisition or retirement for value, of
Indebtedness of the Company or any Guarantor that is subordinated in right of
payment to the Notes or to a Guarantor's Note Guarantee, as the case may be, or
(iv) make any Investment, other than a Permitted Investment, in any Person (such
payments or any other actions described in clauses (i) through (iv) above being
collectively "Restricted Payments") if, at the time of, and after giving effect
to, the proposed Restricted Payment: (A) a Default or Event of Default shall
have occurred and be continuing, (B) the Company could not Incur at least $1.00
of Indebtedness under the first paragraph of Section 4.03 or (C) the aggregate
amount of all Restricted Payments (the amount, if other than in cash, to be
determined in good faith by the Board of Directors, whose determination shall be
conclusive and evidenced by a Board Resolution) made after the Closing Date
shall exceed the sum of (1) 50% of the aggregate amount of the Adjusted
Consolidated Net Income (or, if the Adjusted Consolidated Net Income is a loss,
minus 100% of the amount of such loss) (determined by excluding income resulting
from transfers of assets by the Company or a Restricted Subsidiary to an
Unrestricted Subsidiary) accrued on a cumulative basis during the period (taken
as one accounting period) beginning on the first day of the fiscal quarter
immediately following the Closing Date and ending on the last day of the last
fiscal quarter preceding the Transaction Date for which reports have been filed
with the Commission or provided to the Trustee pursuant to Section 4.17, plus
(2) the aggregate Net Cash Proceeds received by the Company after the Closing
Date from the issuance and sale permitted by the Indenture of its Capital Stock
(other than Disqualified Stock) to a Person who is not a Subsidiary of the
Company, including an issuance or sale permitted by the Indenture of
Indebtedness of the Company for cash subsequent to the Closing Date upon the
conversion of such Indebtedness into Capital Stock (other than Disqualified
Stock) of the Company, or from the issuance to a Person who is not a Subsidiary
of the Company of any options, warrants or other rights to acquire Capital Stock
of the Company (in each case, exclusive of any Disqualified Stock or any
options, warrants or other rights that are redeemable at the option of the
holder, or are required to be redeemed, prior to the Stated Maturity of the
Notes), plus (3) an amount equal to the net reduction in Investments (other than
reductions in Permitted Investments) in any Person resulting from payments of
interest on Indebtedness, dividends, repayments of loans or advances, or other
transfers of assets, in each case to the Company or any Restricted Subsidiary or
from the Net Cash Proceeds from the sale of any such Investment (except, in each
case, to the extent any such payment or proceeds are included in the calculation
of Adjusted Consolidated Net Income), or from redesignations of Unrestricted
Subsidiaries as Restricted Subsidiaries (valued in each case as provided in the
definition of "Investments"), not to exceed, in each case, the amount of
Investments previously made by the Company or any Restricted Subsidiary in such
Person or Unrestricted Subsidiary, minus (4) the sum of the amounts by which the
Pro Forma Consolidated Net Worth after giving effect to each consolidation,
merger and sale of assets effectuated pursuant to clause (iii) under Section
5.01 was less than the Base Consolidated Net Worth immediately prior to such
consolidation, merger and sale of assets, plus (5) $5 million.

          The foregoing provision shall not be violated by reason of: (i) the
payment of any dividend within 60 days after the date of declaration thereof if,
at said date of declaration, such payment would comply with the foregoing
paragraph; (ii) the redemption, repurchase, defeasance or other acquisition or
retirement for value of Indebtedness that is subordinated in right of payment to
the Notes including premium, if any, and accrued and unpaid interest, with the
proceeds of, or in exchange for, Indebtedness Incurred under clause (iii) of the
second paragraph of part (a) of Section 4.03; (iii) the repurchase, redemption
or other acquisition of Capital Stock of the Company or an Unrestricted
Subsidiary (or options, warrants or other rights to acquire such Capital Stock)
in exchange for, or out of the proceeds of a substantially concurrent offering
of, shares of Capital Stock (other than Disqualified Stock) of the Company (or
options, warrants or other rights to acquire such


<PAGE>

Capital Stock); (iv) the making of any principal payment or the repurchase,
redemption, retirement, defeasance or other acquisition for value of
Indebtedness of the Company or any Guarantor which is subordinated in right of
payment to the Notes or the Note Guarantees, as the case may be, in exchange
for, or out of the proceeds of, a substantially concurrent offering of, shares
of the Capital Stock (other than Disqualified Stock) of the Company or any
Guarantor (or options, warrants or other rights to acquire such Capital Stock);
(v) payments or distributions, to dissenting stockholders pursuant to applicable
law, pursuant to or in connection with a consolidation, merger or transfer of
assets that complies with the provisions of the Indenture applicable to mergers,
consolidations and transfers of all or substantially all of the property and
assets of the Company; (vi) Investments acquired in exchange for Capital Stock
(other than Disqualified Stock) of the Company; provided that, except in the
case of clauses (i) and (iii), no Default or Event of Default shall have
occurred and be continuing or occur as a consequence of the actions or payments
set forth therein; or (vii) the purchase or redemption of subordinated
Indebtedness pursuant to asset sale or change of control provisions contained in
the Indenture or other governing instrument relating thereto; provided, however,
that (a) no offer or purchase obligation may be triggered in respect of such
Indebtedness unless a corresponding obligation also arises for the Notes and (b)
in all events, no repurchase or redemption of such Indebtedness may be
consummated unless and until the Company shall have satisfied all repurchase
obligations with respect to any required purchase offer made with respect to the
Notes.

          Each Restricted Payment permitted pursuant to the preceding paragraph
(other than the Restricted Payment referred to in clause (ii) thereof, an
exchange of Capital Stock for Capital Stock or Indebtedness referred to in
clause (iii) or (iv) thereof and an Investment referred to in clause (vi)
thereof), and the Net Cash Proceeds from any issuance of Capital Stock referred
to in clauses (iii) and (iv), shall be included in calculating whether the
conditions of clause (C) of the first paragraph of this Section 4.04 have been
met with respect to any subsequent Restricted Payments. In the event the
proceeds of an issuance of Capital Stock of the Company are used for the
redemption, repurchase or other acquisition of the Notes, or Indebtedness that
is pari passu with the Notes, then the Net Cash Proceeds of such issuance shall
be included in clause (C) of the first paragraph of this Section 4.04 only to
the extent such proceeds are not used for such redemption, repurchase or other
acquisition of Indebtedness.

          SECTION 4.05. Limitation on Dividend and Other Payment Restrictions
Affecting Restricted Subsidiaries. The Company will not, and will not permit any
Restricted Subsidiary to, create or otherwise cause or suffer to exist or become
effective any consensual encumbrance or restriction of any kind on the ability
of any Restricted Subsidiary that is not a Guarantor to (i) pay dividends or
make any other distributions permitted by applicable law on any Capital Stock of
such Restricted Subsidiary owned by the Company or any other Restricted
Subsidiary, (ii) pay any Indebtedness owed to the Company or any other
Restricted Subsidiary, (iii) make loans or advances to the Company or any other
Restricted Subsidiary or (iv) transfer any of its property or assets to the
Company or any other Restricted Subsidiary.

          The foregoing provisions shall not restrict any encumbrances or
restrictions: (i) existing on the Closing Date in the Credit Agreement, the
Indenture or any other agreements in effect on the Closing Date, and any
extensions, refinancings, renewals or replacements of such agreements; provided
that the encumbrances and restrictions in any such extensions, refinancings,
renewals or replacements are no less favorable in any material respect to the
Holders than those encumbrances or restrictions that are then in effect and that
are being extended, refinanced, renewed or replaced; (ii) existing under or by
reason of applicable law; (iii) existing with respect to any Person or the
property or assets of such Person acquired by the Company or any Restricted
Subsidiary, existing at the time of such acquisition and not incurred in
contemplation thereof, which encumbrances or restrictions are not applicable to
any Person or the property or assets of any Person other than such


<PAGE>


Person or the property or assets of such Person so acquired; (iv) in the case of
clause (iv) of the first paragraph of this Section 4.05, (A) that restrict in a
customary manner the subletting, assignment or transfer of any property or asset
that is a lease, license, conveyance or contract or similar property or asset,
(B) existing by virtue of any transfer of, agreement to transfer, option or
right with respect to, or Lien on, any property or assets of the Company or any
Restricted Subsidiary not otherwise prohibited by the Indenture or (C) arising
or agreed to in the ordinary course of business, not relating to any
Indebtedness, and that do not, individually or in the aggregate, detract from
the value of property or assets of the Company or any Restricted Subsidiary in
any manner material to the Company or any Restricted Subsidiary; (v) with
respect to a Restricted Subsidiary and imposed pursuant to an agreement that has
been entered into for the sale or disposition of all or substantially all of the
Capital Stock of, or property and assets of, such Restricted Subsidiary; or (vi)
contained in the terms of any Indebtedness or any agreement pursuant to which
such Indebtedness was issued if (A) the encumbrance or restriction applies only
in the event of a payment default or a default with respect to a financial
covenant contained in such Indebtedness or agreement, (B) the encumbrance or
restriction is not materially more disadvantageous to the Holders of the Notes
than is customary in comparable financings (as determined by the Company) and
(C) the Company determines that any such encumbrance or restriction will not
materially affect the Company's ability to make principal or interest payments
on the Notes. Nothing contained in this Section 4.05 shall prevent the Company
or any Restricted Subsidiary from (1) creating, incurring, assuming or suffering
to exist any Liens otherwise permitted in Section 4.09 or (2) restricting the
sale or other disposition of property or assets of the Company or any of its
Restricted Subsidiaries that secure Indebtedness of the Company or any of its
Restricted Subsidiaries.

          SECTION 4.06. Limitation on the Issuance and Sale of Capital Stock of
Restricted Subsidiaries. The Company will not sell, and will not permit any
Restricted Subsidiary, directly or indirectly, to issue or sell, any shares of
Capital Stock of a Restricted Subsidiary (including options, warrants or other
rights to purchase shares of such Capital Stock) except (i) to the Company or a
Wholly Owned Restricted Subsidiary; (ii) issuances of director's qualifying
shares or sales to foreign nationals of shares of Capital Stock of foreign
Restricted Subsidiaries, to the extent required by applicable law; or (iii) if,
immediately after giving effect to such issuance or sale, such Restricted
Subsidiary would no longer constitute a Restricted Subsidiary and any Investment
in such Person remaining after giving effect to such issuance or sale would have
been permitted to be made under Section 4.04 if made on the date of such
issuance or sale.

          SECTION 4.07. Limitation on Issuances of Guarantees by Restricted
Subsidiaries. The Company will not permit any Restricted Subsidiary that is not
a Guarantor, directly or indirectly, to Guarantee any Indebtedness of the
Company which is pari passu with or subordinate in right of payment to the Notes
("Guaranteed Indebtedness"), unless (i) such Restricted Subsidiary
simultaneously executes and delivers a supplemental indenture to the Indenture
providing for a Guarantee (a "Subsidiary Guarantee") of payment of the Notes by
such Restricted Subsidiary and (ii) such Restricted Subsidiary waives and will
not in any manner whatsoever claim or take the benefit or advantage of, any
rights of reimbursement, indemnity or subrogation or any other rights against
the Company or any other Restricted Subsidiary as a result of any payment by
such Restricted Subsidiary under its Subsidiary Guarantee; provided that this
paragraph shall not be applicable to any Guarantee of any Restricted Subsidiary
that existed at the time such Person became a Restricted Subsidiary and was not
Incurred in connection with, or in contemplation of, such Person becoming a
Restricted Subsidiary. If the Guaranteed Indebtedness is (A) pari passu with the
Notes or the Note Guarantees, then the Guarantee of such Guaranteed Indebtedness
shall be pari passu with, or subordinated to, the Subsidiary Guarantee or (B)
subordinated to the Notes or the Note Guarantees, then the Guarantee of such
Guaranteed Indebtedness shall be subordinated to the Subsidiary Guarantee at
least to the extent that the Guaranteed Indebtedness is subordinated to the
Notes or the Note Guarantees, as the case may be.


<PAGE>


          Notwithstanding the foregoing, any Subsidiary Guarantee by a
Restricted Subsidiary may provide by its terms that it shall be automatically
and unconditionally released and discharged upon (i) any sale, exchange or
transfer, to any Person not an Affiliate of the Company, of all of the Company's
and each Restricted Subsidiary's Capital Stock in, or all or substantially all
the assets of, such Restricted Subsidiary (which sale, exchange or transfer is
not prohibited by the Indenture) or (ii) the release or discharge of the
Guarantee which resulted in the creation of such Subsidiary Guarantee, except a
discharge or release by or as a result of payment under such Guarantee.

          SECTION 4.08. Limitation on Transactions with Shareholders and
Affiliates. The Company will not, and will not permit any Restricted Subsidiary
to, directly or indirectly, enter into, renew or extend any transaction
(including, without limitation, the purchase, sale, lease or exchange of
property or assets, or the rendering of any service) with any holder (or any
Affiliate of such holder) of 5% or more of any class of Capital Stock of the
Company or with any Affiliate of the Company or any Restricted Subsidiary,
except upon fair and reasonable terms no less favorable to the Company or such
Restricted Subsidiary than could be obtained, at the time of such transaction
or, if such transaction is pursuant to a written agreement, at the time of the
execution of the agreement providing therefor, in a comparable arm's-length
transaction with a Person that is not such a holder or an Affiliate.

          The foregoing limitation does not limit, and shall not apply to (i)
transactions (A) approved by a majority of the disinterested members of the
Board of Directors, or (B) for which the Company or a Restricted Subsidiary
delivers to the Trustee a written opinion of a nationally recognized investment

exceeds $1 million in value, must be approved or determined to be fair in the
manner provided for in clause (i)(A) or (B) above and (b) the aggregate amount
of which exceeds $3 million in value, must be determined to be fair in the

          SECTION 4.09. Limitation on Liens. The Company will not, and will not
permit any Restricted Subsidiary to, create, incur, assume or suffer to exist
any Lien on any of its assets or properties of any character, or any shares of

effective provision for all of the Notes (or in the case of a Lien on assets or
properties of a Guarantor, the Note Guarantee of such Guarantor) and all other
amounts due under the Indenture to be directly secured equally and ratably with
(or, if the obligation or liability to be secured by such Lien is subordinated
in right of payment to the Notes or the Note Guarantee, prior to) the obligation
or liability secured by such Lien. The foregoing limitation does not apply to
(i) Liens existing on the Closing Date, including Liens securing obligations
under the Credit Agreement; (ii) Liens granted after the Closing Date on any
assets or Capital Stock of the Company or its Restricted Subsidiaries created in
favor of the Holders; (iii) Liens with respect to the assets of a Restricted

or any Restricted Subsidiary other than the property or assets securing the
Indebtedness being refinanced; (v) Liens on any property or assets of a
Restricted Subsidiary securing Indebtedness of such Restricted Subsidiary
permitted under Section 4.03; or (vi) Permitted Liens.

          SECTION 4.10. Limitation on Sale-Leaseback Transactions. The Company
will not, and will not permit any Restricted Subsidiary to, enter into any
sale-leaseback transaction involving any of its assets or properties whether now
owned or hereafter acquired, whereby the Company or a Restricted Subsidiary
sells or transfers such assets or properties and then or thereafter leases such
assets or properties or any part thereof or any other assets or properties which
the Company or such Restricted Subsidiary, as the case may be, intends to use
for substantially the same purpose or purposes as the assets or properties sold
or transferred.

          The foregoing restriction does not apply to any sale-leaseback
transaction if (i) the lease is for a period, including renewal rights, of not
in excess of three years; (ii) the lease secures or relates to industrial
revenue or pollution control bonds; (iii) the transaction is solely between the
Company and any Wholly Owned Restricted Subsidiary or solely between Wholly
Owned Restricted Subsidiaries; or (iv) the Company or such Restricted
Subsidiary, within 12 months after the sale or transfer of any assets or
properties is completed, applies an amount not less than the net proceeds
received from such sale in accordance with clause (A) or (B) of the first
paragraph of Section 4.11.

          SECTION 4.11. Limitation on Asset Sales. The Company will not, and
will not permit any Restricted Subsidiary to, consummate any Asset Sale, unless
(i) the consideration received by the Company or such Restricted Subsidiary is
at least equal to the fair market value of the assets sold or disposed of and
(ii) at least 75% of the consideration received (including the fair market
value, as determined in good faith by the Board of Directors, of any non-cash
consideration) consists of (w) cash, (x) Temporary Cash Investments, (y)
marketable securities which are liquidated for cash within 90 days following the
consummation of such Asset Sale, and (z) the assumption of Indebtedness of the
Company or any Restricted Subsidiary (other than the Notes and the Note
Guarantees); provided that (1) such Indebtedness is not subordinate in right of
payment to the Notes and the Note Guarantees and (2) the Company or such
Restricted Subsidiary is irrevocably released and discharged from such
Indebtedness. In the event and to the extent that the Net Cash Proceeds received
by the Company or any of its Restricted Subsidiaries from one or more Asset
Sales occurring on or after the Closing Date in any period of 12 consecutive
months exceed 10% of Adjusted Consolidated Net Tangible Assets (determined as of
the date closest to the commencement of such 12-month period for which a
consolidated balance sheet of the Company and its Subsidiaries has been filed
with the Commission), then the Company shall or shall cause the relevant
Restricted Subsidiary to (i) within twelve months after the date Net Cash
Proceeds so received exceed 10% of Adjusted Consolidated Net Tangible Assets (A)
apply an amount equal to such excess Net Cash Proceeds to permanently repay
unsubordinated Indebtedness of the Company, or any Restricted Subsidiary
providing a Subsidiary Guarantee pursuant to Section 4.07 described above or
Indebtedness of any other Restricted Subsidiary, in each case owing to a Person
other than the Company or any of its Restricted Subsidiaries or (B) invest an
equal amount, or the amount not so applied pursuant to clause (A) (or enter into
a definitive agreement committing to so invest within 12 months after the date
of such agreement), in property or assets (other than current assets) of a
nature or type or that are used in a business (or in a company having property
and assets of a nature or type, or engaged in a business) similar or related to
the nature or type of the property and assets of, or the business of, the
Company and its Restricted Subsidiaries existing on the date of such investment
and (ii) apply (no later than the end of the 12-month period referred to in
clause (i)) such excess Net Cash Proceeds (to the extent not applied pursuant to
clause (i)) as provided in the following paragraph of this Section 4.11. The
amount of such excess Net Cash Proceeds required to be applied (or to be
committed to be applied) during such 12-month period as set forth in clause


<PAGE>


(i) of the preceding sentence and not applied as so required by the end of such
period shall constitute "Excess Proceeds."

          If, as of the first day of any calendar month, the aggregate amount of
Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to this
Section 4.11 totals at least $10 million, the Company must commence, not later
than the fifteenth Business Day of such month, and consummate an Offer to
Purchase from the Holders on a pro rata basis an aggregate principal amount of
Notes equal to the Excess Proceeds on such date, at a purchase price equal to
100% of the principal amount of the Notes, plus, in each case, accrued interest
(if any) to the Payment Date. In the event that more than 98% of the outstanding
principal amount of the Notes are tendered pursuant to such Offer to Purchase,
the balance of the Notes will be redeemable, at the Company's option, in whole
or in part, at any time or from time to time thereafter, at a Redemption Price
equal to the price specified in such Offer to Purchase plus accrued and unpaid
interest, if any, to the Redemption Date (subject to the right of Holders of
record on the relevant Regular Record Date that is on or prior to the Redemption
Date to receive interest due on an Interest Payment Date).

          SECTION 4.12. Repurchase of Notes upon a Change of Control. The
Company must commence, within 30 days of the occurrence of a Change of Control,
and consummate an Offer to Purchase for all Notes then outstanding, at a
purchase price equal to 101% of the principal amount thereof, plus accrued
interest (if any) to the Payment Date. In the event that more than 98% of the
outstanding principal amount of the Notes are tendered pursuant to such Offer to
Purchase, the balance of the Notes will be redeemable, at the Company's option,
in whole or in part, at any time or from time to time thereafter, at a
Redemption Price equal to the price specified in such Offer to Purchase plus
accrued and unpaid interest, if any, to the Redemption Date (subject to the
right of Holders of record on the relevant Regular Record Date that is on or
prior to the Redemption Date to receive interest due on an Interest Payment
Date).

          SECTION 4.13. Existence. Subject to Articles Four and Five of this
Indenture, the Company will do or cause to be done all things necessary to
preserve and keep in full force and effect its existence and the existence of
each of its Restricted Subsidiaries in accordance with the respective
organizational documents of the Company and each such Restricted Subsidiary and
the rights (whether pursuant to charter, partnership certificate, agreement,
statute or otherwise), licenses and franchises of the Company and each such
Restricted Subsidiary; provided that the Company shall not be required to
preserve any such right, license or franchise, or the existence of any
Restricted Subsidiary, if the maintenance or preservation thereof is no longer
desirable in the conduct of the business of the Company and its Restricted
Subsidiaries taken as a whole.

          SECTION 4.14. Payment of Taxes and Other Claims. The Company will pay
or discharge and shall cause each of its Restricted Subsidiaries to pay or
discharge, or cause to be paid or discharged, before the same shall become
delinquent (i) all material taxes, assessments and governmental charges levied
or imposed upon (a) the Company or any such Restricted Subsidiary, (b) the
income or profits of any such Subsidiary which is a corporation or (c) the
property of the Company or any such Restricted Subsidiary and (ii) all material
lawful claims for labor, materials and supplies that, if unpaid, might by law
become a lien upon the property of the Company or any such Restricted
Subsidiary; provided that the Company shall not be required to pay or discharge,
or cause to be paid or discharged, any such tax, assessment, charge or claim the
amount, applicability or validity of which is being contested in good faith by
appropriate proceedings and for which adequate reserves have been established.

          SECTION 4.15. Maintenance of Properties and Insurance. The Company
will cause all properties used or useful in the conduct of its business or the
business of any Restricted Subsidiary and material to the Company and its
Restricted Subsidiaries taken as a whole, to be


<PAGE>

maintained and kept in good condition, repair and working order and supplied
with all necessary equipment and will cause to be made all necessary repairs,
renewals, replacements, betterments and improvements thereof, all as in the
judgment of the Company may be necessary so that the business carried on in
connection therewith may be properly and advantageously conducted at all times;
provided that nothing in this Section 4.15 shall prevent the Company or any such
Restricted Subsidiary from discontinuing the use, operation or maintenance of
any of such properties or disposing of any of them, if such discontinuance or
disposal is, in the judgment of the Company or of such Restricted Subsidiary
having managerial responsibility for any such property, desirable in the conduct
of the business of the Company or such Restricted Subsidiary.

          The Company will provide or cause to be provided, for itself and its
Restricted Subsidiaries, insurance (including appropriate self-insurance)
against loss or damage of the kinds customarily insured against by corporations
similarly situated and owning like properties, with reputable insurers or with
the government of the United States of America, or an agency or instrumentality
thereof, in such amounts, with such deductibles and by such methods as the
Company in good faith shall determine to be reasonable and appropriate in the
circumstances.

          SECTION 4.16. Compliance Certificates. (a) Each of the Company and
each Guarantor shall deliver to the Trustee, within 90 days after the end of the
Company's and each Guarantor's fiscal year, an Officers' Certificate signed by
the Chief Financial Officer of the Company or the Guarantor, as applicable, and
another senior executive Officer of the Company or the Guarantor, as applicable,
stating whether or not the signers know of any Default or Event of Default that
occurred during such fiscal year. If any of the signers of the Officers'
Certificate have knowledge of such a Default or Event of Default, the
certificate shall describe any such Default or Event of Default and its status.

          (b) The Company shall, so long as any of the Notes are outstanding,
deliver to the Trustee, forthwith upon any Officer becoming aware of any Default
or Event of Default, an Officers' Certificate specifying such Default or Event
of Default and what action the Company is taking or proposes to take with
respect thereto.

          SECTION 4.17. Commission Reports and Reports to Holders. The Company
shall file with the Commission the annual, quarterly and other reports and other
information required by Section 13(a) or 15(d) of the Exchange Act, regardless
of whether such sections of the Exchange Act are applicable to the Company, and
shall mail or cause to be mailed copies of such reports to Holders and the
Trustee within 15 days after the date it would have been required to file such
reports with the Commission had it been subject to such sections; provided,
however, that the copies of such reports mailed to Holders may omit exhibits,
which the Company will supply to any Holder at such Holder's request. The
Company also shall comply with the other provisions of TIA Section 314(a).

          SECTION 4.18. Waiver of Stay, Extension or Usury Laws. The Company and
each of the Guarantors covenant (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any stay or extension law or any usury law
or other law that would prohibit or forgive the Company or any Guarantor from
paying all or any portion of the principal of, premium, if any, or interest on
the Notes as contemplated herein, wherever enacted, now or at any time hereafter
in force, or that may affect the covenants or the performance of this Indenture;
and (to the extent that it may lawfully do so) the Company and each of the
Guarantors hereby expressly waive all benefit or advantage of any such law and
covenants that it will not hinder, delay or impede the execution of any power
herein granted to the Trustee, but will suffer and permit the execution of every
such power as though no such law had been enacted.

                              SUCCESSOR CORPORATION

          SECTION 5.01. When Company May Merge, Etc. Neither the Company nor any
Guarantor will consolidate with, merge with or into, or sell, convey, transfer,
lease or otherwise dispose of all or substantially all of its property and
assets (as an entirety or substantially an entirety in one transaction or a
series of related transactions) to, any Person or permit any Person to merge
with or into the Company or any Guarantor unless:

          (i) the Company or the Guarantor, as the case may be, shall be the
     continuing Person, or the Person (if other than the Company or the
     Guarantor) formed by such consolidation or into which the Company or the
     Guarantor, as the case may be, is merged or that acquired or leased such
     property and assets of the Company or the Guarantor, as the case may be,
     shall be a corporation organized and validly existing under the laws of the
     United States of America or any jurisdiction thereof and shall expressly
     assume, by a supplemental indenture, executed and delivered to the Trustee,
     all of the obligations of the Company or the Guarantor, as the case may be,
     on all of the Notes or the Note Guarantees, as the case may be, and under
     the Indenture;

          (ii) immediately after giving effect to such transaction, no Default
     or Event of Default shall have occurred and be continuing;

          (iii) immediately after giving effect to such transaction on a pro
     forma basis, the Company or any Guarantor, as the case may be, or any
     Person becoming the successor obligor of the Notes or the Note Guarantees,
     as the case may be, shall have a Consolidated Net Worth (a "Pro Forma
     Consolidated Net Worth") which is equal to or greater than the Consolidated
     Net Worth of the Company or the Guarantor, as the case may be, immediately
     prior to such transaction (the "Base Consolidated Net Worth"), or if the
     Pro Forma Consolidated Net Worth is less than the Base Consolidated Net
     Worth, the amount by which the Pro Forma Consolidated Net Worth is less
     than the Base Consolidated Net Worth shall, if considered as a Restricted
     Payment, be permitted to be paid at the time under Section 4.04;

          (iv) immediately after giving effect to such transaction on a pro
     forma basis the Company or any Guarantor, as the case may be, or any Person

     case may be, could Incur at least $1.00 of Indebtedness under the first
     paragraph of Section 4.03; provided that this clause (iv) shall not apply
     to a consolidation or merger with or into a Wholly Owned Restricted
     Subsidiary with a positive net worth; and provided further that, in
     connection with any such merger or consolidation, no consideration (other
     than Capital Stock (other than Disqualified Stock) in the surviving Person,
     the Company or any Guarantor) shall be issued or distributed to the
     stockholders of the Company or the Guarantor; and

          (v) the Company delivers to the Trustee an Officers' Certificate
     (attaching the arithmetic computations to demonstrate compliance with
     clauses (iii) and (iv)) and Opinion of Counsel, in each case stating that
     such consolidation, merger or transfer and such supplemental indenture
     complies with this provision and that all conditions precedent provided for
     herein relating to such transaction have been complied with;

provided, however, that clauses (iii) and (iv) above do not apply if, in the
good faith determination of the Board of Directors of the Company, whose
determination shall be evidenced by a Board Resolution, the principal purpose of
such transaction is to change the state of incorporation of the


<PAGE>

Company or any Guarantor; and provided further that any such transaction shall
not have as one of its purposes the evasion of the foregoing limitations.

          SECTION 5.02. Successor Substituted. Upon any consolidation or merger,
or any sale, conveyance, transfer or other disposition of all or substantially
all of the property and assets of the Company or any Guarantor in accordance
with Section 5.01 of this Indenture, the successor Person formed by such
consolidation or into which the Company or any Guarantor is merged or to which
such sale, conveyance, transfer or other disposition is made shall succeed to,
and be substituted for, and may exercise every right and power of, the Company
or any Guarantor, as the case may be, under this Indenture with the same effect
as if such successor Person had been named as the Company or any Guarantor, as
the case may be, herein; provided, however, that in the case of a lease, the
Company or any Guarantor, as the case may be, shall not be released from the

                              DEFAULT AND REMEDIES

          SECTION 6.01. Events of Default. An "Event of Default" shall occur
with respect to the Notes if:

          (a) the Company or any Guarantor, as the case may be, defaults in the

     becomes due and payable at Stated Maturity, upon acceleration, redemption
     or otherwise;

          (b) the Company or any Guarantor, as the case may be, defaults in the
     payment of interest on any Note when the same becomes due and payable, and
     such default continues for a period of 30 days;

          (c) the Company or any Guarantor, as the case may be, defaults in the

     specified in clause (a), (b) or (c) above) and such default or breach
     continues for a period of 30 consecutive days after written notice by the
     Trustee or the Holders of 25% or more in aggregate principal amount of the
     Notes;

          (e) there occurs with respect to any issue or issues of Indebtedness
     of the Company, any Guarantor or any Significant Subsidiary having an
     outstanding principal amount of $10 million or more in the aggregate for
     all such issues of all such Persons, whether such Indebtedness now exists
     or shall hereafter be created, (I) an event of default that has caused the
     holder thereof to declare such Indebtedness to be due and payable prior to
     its Stated Maturity and such Indebtedness has not been discharged in full
     or such acceleration has not been rescinded or annulled within 30 days of
     such acceleration and/or (II) the failure to make a principal payment at
     the final (but not any interim) fixed maturity and such defaulted payment
     shall not have been made, waived or extended within 30 days of such payment
     default;


<PAGE>


          (f) any final judgment or order (not covered by insurance) for the
     payment of money in excess of $10 million in the aggregate for all such
     final judgments or orders against all such Persons (treating any
     deductibles, self-insurance or retention as not so covered) shall be
     rendered against the Company, any Guarantor or any Significant Subsidiary
     and shall not be paid or discharged, and there shall be any period of 30
     consecutive days during which a stay of enforcement of such final judgment
     or order, by reason of a pending appeal or otherwise, shall not be in
     effect;

          (g) a court having jurisdiction in the premises enters a decree or
     order for (A) relief in respect of the Company or any Significant
     Subsidiary in an involuntary case under any applicable bankruptcy,
     insolvency or other similar law now or hereafter in effect, (B) appointment
     of a receiver, liquidator, assignee, custodian, trustee, sequestrator or
     similar official of the Company or any Significant Subsidiary or for all or
     substantially all of the property and assets of the Company or any
     Significant Subsidiary or (C) the winding up or liquidation of the affairs

     days;

          (h) the Company or any Significant Subsidiary (A) commences a

     appointment of or taking possession by a receiver, liquidator, assignee,

     Significant Subsidiary or for all or substantially all of the property and
     assets of the Company or any Significant Subsidiary or (C) effects any
     general assignment for the benefit of creditors; or

          (i) any Note Guarantee ceases to be in full force and effect (except
     pursuant to its terms) or is declared null and void or any Guarantor denies
     that it has any further liability under any Note Guarantee, or gives notice
     to such effect.

          SECTION 6.02. Acceleration. If an Event of Default (other than an
Event of Default specified in clause (g) or (h) of Section 6.01 that occurs with
respect to the Company or any Guarantor) occurs and is continuing under this
Indenture, the Trustee or the Holders of at least 25% in aggregate principal
amount of the Notes, then outstanding, by written notice to the Company (and to
the Trustee if such notice is given by the Holders), may, and the Trustee at the
request of such Holders shall, declare the principal of, premium, if any, and
accrued interest on the Notes to be immediately due and payable. Upon a
declaration of acceleration, such principal of, premium, if any, and accrued
interest shall be immediately due and payable. In the event of a declaration of
acceleration because an Event of Default set forth in clause (e) of Section 6.01
has occurred and is continuing, such declaration of acceleration shall be
automatically rescinded and annulled if the event of default triggering such
Event of Default pursuant to clause (e) shall be remedied or cured by the
Company, any Guarantor or the relevant Significant Subsidiary or waived by the
holders of the relevant Indebtedness within 60 days after the declaration of
acceleration with respect thereto. If an Event of Default specified in clause
(g) or (h) of Section 6.01 occurs with respect to the Company or any Significant
Subsidiary, the principal of, premium, if any, and accrued interest on the Notes
then outstanding shall ipso facto become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any Holder.

          At any time after such a declaration of acceleration, but before a
judgment or decree for the payment of the money due has been obtained by the
Trustee, the Holders of at least a majority in principal amount of the
outstanding Notes by written notice to the Company and to the Trustee, may waive
all past defaults and rescind and annul a declaration of acceleration and its
consequences if (i) all existing Events of Default, other than the nonpayment of
the principal of, premium, if any,


<PAGE>

and interest on the Notes that have become due solely by such declaration of
acceleration, have been cured or waived and (ii) the rescission would not
conflict with any judgment or decree of a court of competent jurisdiction.

          SECTION 6.03. Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy by proceeding at law or
in equity to collect the payment of principal of, premium, if any, or interest
on the Notes or to enforce the performance of any provision of the Notes or this
Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Notes or does not produce any of them in the proceeding.

          SECTION 6.04. Waiver of Past Defaults. Subject to Sections 6.02, 6.07
and 9.02, the Holders of at least a majority in aggregate principal amount of
the outstanding Notes, by notice to the Trustee, may waive an existing Default
or Event of Default and its consequences, except a Default in the payment of
principal of, premium, if any, or interest on any Note as specified in clause
(a) or (b) of Section 6.01 (including in connection with an Offer to Purchase)
or in respect of a covenant or provision of this Indenture which cannot be
modified or amended without the consent of the Holder of each outstanding Note
affected. Upon any such waiver, such Default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other Default or Event of Default or impair any right consequent thereto.

          SECTION 6.05. Control by Majority. The Holders of at least a majority
in aggregate principal amount of the outstanding Notes, by notice to the
Trustee, may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power
conferred on the Trustee; provided that the Trustee may refuse to follow any
direction that conflicts with law or this Indenture, that may involve the
Trustee in personal liability, or that the Trustee determines in good faith may
be unduly prejudicial to the rights of Holders not joining in the giving of such
direction; and provided further that the Trustee may take any other action it
deems proper that is not inconsistent with any directions received from Holders
of Notes pursuant to this Section 6.05.

          SECTION 6.06. Limitation on Suits. A Holder may not institute any
proceeding, judicial or otherwise, with respect to this Indenture or the Notes,
or for the appointment of a receiver or trustee, or pursue any other remedy
hereunder, unless:

          (i) such Holder has previously given the Trustee written notice of a
     continuing Event of Default;

          (ii) the Holders of at least 25% in aggregate principal amount of
     outstanding Notes shall have made a written request to the Trustee to
     institute proceedings in respect of such Event of Default in its own name
     as Trustee hereunder;

          (iii) such Holder or Holders have offered to the Trustee indemnity
     satisfactory to the Trustee against any costs, liability or expense
     incurred in compliance with such request;

          (iv) the Trustee for 60 days after its receipt of such notice, request
     and offer of indemnity has failed to institute any such proceeding; and


<PAGE>


          (v) during such 60-day period, the Holders of a majority in aggregate
     principal amount of the outstanding Notes have not given the Trustee a
     direction that is inconsistent with such written request.

          For purposes of Section 6.05 of this Indenture and this Section 6.06,
the Trustee shall comply with TIA Section 316(a) in making any determination of
whether the Holders of the required aggregate principal amount of outstanding
Notes have concurred in any request or direction of the Trustee to pursue any
remedy available to the Trustee or the Holders with respect to this Indenture or
the Notes or otherwise under the law.

          A Holder may not use this Indenture to prejudice the rights of another
Holder or to obtain a preference or priority over such other Holder.

          SECTION 6.07. Rights of Holders to Receive Payment. Notwithstanding
any other provision of this Indenture, the right of any Holder of a Note to
receive payment of the principal amount of, premium, if any, or interest on such
Holder's Note on or after the respective due dates expressed on such Note
(including in a notice with respect to an Offer to Purchase), or to bring suit
for the enforcement of any such payment on or after such respective dates, shall
not be impaired or affected without the consent of such Holder.

          SECTION 6.08. Collection Suit by Trustee. If an Event of Default in
payment of principal, premium or interest specified in clause (a) or (b) of
Section 6.01 occurs and is continuing, the Trustee may recover judgment in its
own name and as trustee of an express trust against the Company or any other
obligor of the Notes for the whole amount of principal, premium, if any, and
accrued interest remaining unpaid, together with interest on overdue principal,
premium, if any, and, to the extent that payment of such interest is lawful,
interest on overdue installments of interest, in each case at the rate specified
in the Notes, and such further amount as shall be sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

          SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may file
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee (including any claim for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.06) and the Holders allowed in any judicial proceedings relative to
the Company (or any other obligor of the Notes), its creditors or its property
and shall be entitled and empowered to collect and receive any monies,
securities or other property payable or deliverable upon conversion or exchange
of the Notes or upon any such claims and to distribute the same, and any
custodian, receiver, assignee, trustee, liquidator, sequestrator or other
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agent and counsel, and any other
amounts due the Trustee under Section 7.06. Nothing herein contained shall be
deemed to empower the Trustee to authorize or consent to, or accept or adopt on
behalf of any Holder, any plan of reorganization, arrangement, adjustment or
composition affecting the Notes or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

          SECTION 6.10. Priorities. If the Trustee collects any money pursuant
to this Article Six, it shall pay out the money in the following order:


<PAGE>

          First: to the Trustee for amounts due under Section 7.06, including
     payment of all compensation, expense and liabilities incurred, and all
     advances made, by the Trustee and the costs and expenses of collection;

          Second: to Holders for amounts then due and unpaid for principal
     amount of, premium, if any, and interest on the Notes in respect of which
     or for the benefit of which such money has been collected, ratably, without
     preference or priority of any kind, according to the amounts due and
     payable on such Notes for principal, premium, if any, and interest,
     respectively; and

          Third: to the Company or any other obligors of the Notes, as their
     interests may appear, or as a court of competent jurisdiction may direct.

          The Trustee, upon prior written notice to the Company, may fix a
record date and payment date for any payment to Holders pursuant to this Section
6.10.

          SECTION 6.11. Undertaking for Costs. In any suit for the enforcement
of any right or remedy under this Indenture or in any suit against the Trustee
for any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees, against any party litigant in the
suit having due regard to the merits and good faith of the claims or defenses
made by the party litigant. This Section 6.11 does not apply to a suit by the
Trustee, a suit by a Holder pursuant to Section 6.07 of this Indenture, or a
suit by Holders of more than 10% in principal amount of the outstanding Notes.

          SECTION 6.12. Restoration of Rights and Remedies. If the Trustee or
any Holder has instituted any proceeding to enforce any right or remedy under
this Indenture and such proceeding has been discontinued or abandoned for any
reason, or has been determined adversely to the Trustee or to such Holder, then,
and in every such case, subject to any determination in such proceeding, the
Company, the Trustee and the Holders shall be restored severally and
respectively to their former positions hereunder and thereafter all rights and
remedies of the Company, Trustee and the Holders shall continue as though no
such proceeding had been instituted.

          SECTION 6.13. Rights and Remedies Cumulative. Except as otherwise
provided with respect to the replacement or payment of mutilated, destroyed,
lost or wrongfully taken Notes in Section 2.09, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

          SECTION 6.14. Delay or Omission Not Waiver. No delay or omission of
the Trustee or of any Holder to exercise any right or remedy accruing upon any
Event of Default shall impair any such right or remedy or constitute a waiver of
any such Event of Default or an acquiescence therein. Every right and remedy
given by this Article Six or by law to the Trustee or to the Holders may be
exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders, as the case may be.

                                     TRUSTEE

          SECTION 7.01. Rights and Duties of Trustee. (i) Except during the
continuance of an Event of Default,

          (a) the Trustee undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture, and no implied covenants
     or obligations shall be read into this Indenture against the Trustee; and

          (b) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth and correctness of the statements and
     certificates or opinions furnished to it and conforming to the requirements
     of this Indenture; but in the case of any such certificates or opinions
     which by any provision hereof are specifically required to be furnished to
     the Trustee, the Trustee shall be under a duty to examine the same to
     determine whether or not they conform to the requirements of this
     Indenture.

          (ii) In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in its exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

          (iii) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that:

          (a) this Subsection shall not be construed to limit the effect of
     Subsection (i) of this Section;

          (b) the Trustee shall not be liable for any error of judgment made in
     good faith by a Responsible Officer, unless it shall be proved that the
     Trustee was negligent in ascertaining the pertinent facts; and

          (c) the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the direction
     of the Holders of a majority in principal amount of the outstanding Notes,
     relating to the time, method and place of conducting any proceeding for
     exercising any remedy available to the Trustee, or exercising any trust or
     power conferred upon the Trustee, under this Indenture with respect to the
     Notes.

          (iv) Subject to TIA Sections 315(a) through (d):

          (a) the Trustee may rely upon any document believed by it to be
     genuine and to have been signed or presented by the proper person. The
     Trustee need not investigate any fact or matter stated in the document;

          (b) before the Trustee acts or refrains from acting, it may require an
     Officers' Certificate or an Opinion of Counsel, which shall conform to
     Section 11.04. The Trustee shall not be liable for any action it takes or
     omits to take in good faith in reliance on such certificate or opinion;

          (c) the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request or direction
     of any of the Holders, unless such


<PAGE>

     Holders shall have offered to the Trustee reasonable security or indemnity
     against the costs, expenses and liabilities that might be incurred by it in
     compliance with such request or direction;

          (d) the Trustee shall not be liable for any action it takes or omits
     to take in good faith that it believes to be authorized or within its
     rights or powers; provided that the Trustee's conduct does not constitute
     negligence or bad faith;

          (e) no provision of this Indenture shall require the Trustee to expend
     or risk its own funds or otherwise incur any financial liability in the
     performance of any of its duties hereunder, or in the exercise of any of
     its rights or powers, if it shall have reasonable grounds for believing
     that repayment of such funds or adequate indemnity against such risk or
     liability is not reasonably assured to it;

          (f) whenever in the administration of this Indenture the Trustee shall
     deem it desirable that a matter be proved or established prior to taking,
     suffering or omitting any action hereunder, the Trustee (unless other
     evidence be herein specifically prescribed), may, in the absence of bad
     faith on its part, rely upon an Officers' Certificate;

          (g) the Trustee may consult with counsel and the advice of such
     counsel or any opinion of counsel shall be full and complete authorization
     and protection in respect of any action taken, suffered or omitted by it
     hereunder in good faith and in reliance thereon;

          (h) the Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or
     document, but the Trustee, in its discretion, may make such further inquiry
     or investigation into such facts or matters as it may see fit, and, if the
     Trustee shall determine to make such further inquiry or investigation, it
     shall be entitled to examine the books, records and premises of the Company
     or any Guarantor, personally or by agent or attorney;

          (i) the Trustee may execute any of the trusts or powers hereunder
     either directly or by or through agents or attorneys and the Trustee shall
     not be responsible for any misconduct or negligence on the part of any
     agent or attorney appointed with due care by it hereunder;

          (j) the Trustee may conclusively rely as to the identity and addresses
     of Holders and other matters contained therein on the register of the Notes
     maintained by the Registrar pursuant to Section 2.04 hereof and shall not
     be affected by notice to the contrary; and

          (k) unless otherwise specifically provided in this Indenture, any
     demand, request, direction or notice from the Company shall be sufficient
     if signed by an Officer of the Company.

          SECTION 7.02. Individual Rights of Trustee. The Trustee, in its
individual or any other capacity, may become the owner or pledgee of Notes and
may otherwise deal with the Company, the Guarantors or their Affiliates with the
same rights it would have if it were not the Trustee. Any Agent may do the same
with like rights. However, the Trustee must comply with Sections 7.09 and 7.11.

          SECTION 7.03. Trustee's Disclaimer. The Trustee (i) shall not be
responsible for and makes no representation as to the validity or adequacy of
this Indenture or the Notes, (ii) shall


<PAGE>

not be accountable for the Company's use of the proceeds from the Notes (iii)
shall not be responsible for the use or application of any money received by any
Paying Agent other than the Trustee, and (iv) shall not be responsible for any
statement in the Notes other than its certificate of authentication.

          SECTION 7.04. Notice of Default. If any Default or any Event of
Default occurs and is continuing and if such Default or Event of Default is
known to a Responsible Officer of the Trustee, the Trustee shall mail to each
Holder in the manner and to the extent provided in TIA Section 313(c) notice of
the Default or Event of Default within 45 days after it occurs, unless such
Default or Event of Default has been cured or waived; provided, however, that,
except in the case of a default in the payment of the principal of, premium, if
any, or interest on any Note, the Trustee shall be protected in withholding such
notice if and so long as the board of directors, the executive committee or a
trust committee of directors and/or Responsible Officers of the Trustee in good
faith determine that the withholding of such notice is in the interest of the
Holders.

          The Trustee shall not be deemed to have knowledge of any Default or
Event of Default except (i) a default described in Section 6.01(a) or (b) so
long as the Trustee is the Paying Agent or (ii) any Default or Event of Default
of which the Trustee shall have received written notification or a Responsible
Officer charged with the administration of this Indenture shall have obtained
actual knowledge, and such notification shall not be deemed to include receipt
of information obtained in any report or other reports and documents furnished
under Section 4.16 of this Indenture which reports and documents the Trustee
shall have no duty to examine.

          SECTION 7.05. Reports by Trustee to Holders. Within 60 days after each
May 15, beginning with May 15, 1998, the Trustee shall mail to each Holder as
provided in TIA Section 313(c) a brief report dated as of such May 15, if
required by TIA Section 313(a).

          A copy of each report at the time of its mailing to the Holders of
Notes shall be mailed to the Company and filed with the Commission and each
stock exchange on which the Notes are listed in accordance with TIA Section
313(d). The Company shall promptly notify the Trustee when the Notes are listed
on any stock exchange or of any delisting thereof.

          SECTION 7.06. Compensation and Indemnity. The Company and the
Guarantors, jointly and severally, shall pay to the Trustee such compensation as
shall be agreed upon in writing for its services hereunder. The compensation of
the Trustee shall not be limited by any law on compensation of a trustee of an
express trust. The Company and the Guarantors, jointly and severally, shall
reimburse the Trustee promptly upon request for all reasonable disbursements,
expenses and advances incurred or made by it in addition to compensation for its
services. Such expenses shall include the reasonable compensation, disbursements
and expenses of the Trustee's agents and counsel.

          The Company and the Guarantors, jointly and severally, shall indemnify
the Trustee for, and hold it harmless against, any loss or liability or expense
incurred by it without negligence or bad faith on its part in connection with
the acceptance or administration of this Indenture and its duties under this
Indenture and the Notes, including the costs and expenses of defending itself
against any claim or liability and of complying with any process served upon it
or any of its officers in connection with the exercise or performance of any of
its powers or duties under this Indenture and the Notes. The Trustee shall
notify the Company promptly of any claim asserted against the Trustee for which
it may seek indemnity. The Company shall defend the claim and the Trustee shall
cooperate in the defense. The Trustee may have separate counsel and the Company
shall pay reasonable fees and expenses of such counsel. The Company need not pay
for any settlements made without its consent; provided that such consent shall
not be unreasonably withheld. The Company


<PAGE>


need not reimburse any expense or indemnity against any loss or liability
incurred by the Trustee through negligence or bad faith.

          The Trustee shall have a claim prior to the Notes on all money or
property held or collected by the Trustee, in its capacity as Trustee, for any
amount owing it pursuant to this Section 7.06, except money or property held in
trust to pay principal of, premium, if any, and interest on particular Notes.

          If the Trustee incurs expenses or renders services after the
occurrence of an Event of Default specified in clause (g) or (h) of Section
6.01, the expenses and the compensation for the services (including the
reasonable fees and expenses of its agents and counsel) will be intended to
constitute expenses of administration under Title 11 of the United States
Bankruptcy Code or any applicable federal or state law for the relief of
debtors.

          To the extent that the payment of any such compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under this Section 7.06 out of the estate in any such
proceeding, shall be denied for any reason, other than solely because of the
misconduct of the Trustee or its Agents, payment of the same shall be secured by
a Lien on, and shall be paid out of, any and all distributions, dividends,
money, securities and other properties that the Holders may be entitled to
receive in such proceeding whether in liquidation or under any plan of
reorganization or arrangement or otherwise.

          The provisions of this Section 7.06 shall survive the termination of
this Indenture.

          The Trustee shall comply with the provisions of TIA Section 313(b)(2)
to the extent applicable.

          SECTION 7.07. Replacement of Trustee. A resignation or removal of the
Trustee and appointment of a successor Trustee shall become effective only upon
the successor Trustee's acceptance of appointment as provided in this Section
7.07.

          The Trustee may resign by so notifying the Company in writing at least
30 days prior to the date of the proposed resignation. The Holders of a majority
in principal amount of the outstanding Notes may remove the Trustee by so
notifying the Trustee in writing and may appoint a successor Trustee with the
consent of the Company. The Company may remove the Trustee if:

          (i) the Trustee fails to comply with Section 7.09;

          (ii) the Trustee is adjudged a bankrupt or an insolvent;

          (iii) a receiver or other public officer takes charge of the Trustee
     or its property; or

          (iv) the Trustee becomes incapable of acting.

          If the Trustee resigns or is removed, or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in aggregate principal amount of the outstanding Notes may appoint
a successor Trustee to replace the successor Trustee appointed by the Company.
If the successor Trustee does not take office within 60 days after the retiring
Trustee resigns or is removed, the retiring Trustee, the Company or the Holders
of a majority in principal


<PAGE>


amount of the outstanding Notes may petition any court of competent jurisdiction
for the appointment of a successor Trustee.

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately after the
delivery of such written acceptance, subject to the lien provided in Section
7.06, (i) the retiring Trustee shall transfer all property held by it as Trustee
to the successor Trustee, (ii) the resignation or removal of the retiring
Trustee shall become effective and (iii) the successor Trustee shall have all
the rights, powers and duties of the Trustee under this Indenture. A successor
Trustee shall mail notice of its succession to each Holder.

          If the Trustee fails to comply with Section 7.09, any Holder who
satisfies the requirements of TIA Section 310(b) may petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a
successor Trustee. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, the Trustee shall resign
immediately in the manner and with the effect provided in this Section.

          Notwithstanding replacement of the Trustee pursuant to this Section
7.07, the Company's obligation under Section 7.06 shall continue for the benefit
of the retiring Trustee.

          SECTION 7.08. Successor Trustee by Merger, Etc. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all of its corporate trust business to, another corporation or national banking
association, the resulting, surviving or transferee corporation or national
banking association without any further act shall be the successor Trustee with
the same effect as if the successor Trustee had been named as the Trustee
herein.

          SECTION 7.09. Eligibility; Disqualification. Any Trustee serving
hereunder shall be a bank or trust company, within or without the state, which
is authorized by law to perform all of the duties imposed upon it hereby and
which either (i) has a reported capital and surplus aggregating at least $25
million or (ii) is a wholly owned subsidiary of a bank, a trust company or a
bank holding company having a reported capital and surplus aggregating at least
$25 million, and shall at all times satisfy the requirements of TIA Section
310(a)(i). The Trustee shall comply with TIA Section 310(b); provided, however,
that there shall be excluded from the operation of TIA Section 310(b)(1) any
indenture or indentures under which other securities or certificates of interest
or participation in other securities of the Company are outstanding if the
requirements for such exclusion set forth in TIA Section 310(b)(1) are met.

          SECTION 7.10. Money Held in Trust. The Trustee shall not be liable for
interest on any money received by it except as the Trustee may agree with the
Company. Money held in trust by the Trustee need not be segregated from other
funds except to the extent required by law and except for money held in trust
under Article Eight of this Indenture.

          SECTION 7.11. Preferential Collection of Claims Against Company. The
Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated.

     the payment of principal and interest in accordance with their terms not
     later than one day prior to the relevant due date, principal, premium, if,
     any, and interest on the Notes to maturity or redemption, as the case may

each Guarantor will be deemed to have paid and will be discharged from any and
all obligations in respect of the Notes and the Note Guarantees on the 123rd day

     referred to in this clause (A), money in an amount sufficient in the
     opinion of a nationally recognized firm of independent public accountants
     expressed in a written certification thereof delivered to the Trustee to
     pay the principal of, premium, if any, and accrued interest on the Notes on

     of Counsel to the effect that Holders will not recognize income, gain or
     loss for federal income tax purposes as a result of the Company's or any
     Guarantor's exercise of its option under this Section 8.02 provision and
     will be subject to federal income tax on the same amount and in the same
     manner and at the same times as would have been the case if such deposit,
     defeasance and discharge had not occurred, which Opinion of Counsel must be
     based upon (and accompanied by a copy of) a ruling of the Internal Revenue
     Service to the same effect unless there has been a change in applicable
     federal income tax law after the date of this Indenture such that a ruling
     is no longer required or (y) a ruling directed to the Trustee received from
     the Internal Revenue Service to the same effect as the aforementioned
     Opinion of Counsel and (ii) an Opinion of Counsel to the effect that the
     creation of the defeasance trust does not violate the Investment Company
     Act of 1940;

          (C) immediately after giving effect to such deposit on a pro forma
     basis, no Event of Default, or event that after the giving of notice or
     lapse of time or both would become an Event of Default, shall have occurred
     and be continuing on the date of such deposit or during the period ending
     on the 123rd day after the date of such deposit, and such deposit shall not
     result in a breach or violation of, or constitute a default under, any
     other agreement or instrument to which the Company or any of its
     Subsidiaries is a party or by which the Company or any of its Subsidiaries
     is bound;

          (D) if at such time the Notes are listed on a national securities
     exchange, the Company has delivered to the Trustee an Opinion of Counsel to
     the effect that the Notes will not be delisted as a result of such deposit,
     defeasance and discharge; and

          (E) the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, in each case stating that all conditions
     precedent provided for herein relating to the defeasance contemplated by
     this Section 8.02 have been complied with.

          Notwithstanding the foregoing, prior to the end of the 123-day (or one
year) period referred to in clause (B)(ii) of this Section 8.02, none of the
Company's or Guarantors' obligations under this Indenture shall be discharged.
Subsequent to the end of such 123-day (or one year) period with respect to this
Section 8.02, the Company's and each Guarantor's obligations in Sections 2.03,
2.04, 2.05, 2.06, 2.09, 2.14, 4.01, 4.02, 7.06, 7.07, 8.04, 8.05 and 8.06 shall
survive until the Notes are no longer outstanding. Thereafter, only the
Company's and the Guarantors' obligations in Sections 7.06, 8.05 and 8.06 shall
survive. If and when a ruling from the Internal Revenue Service or an Opinion of
Counsel referred to in clause (B)(i) of this Section 8.02 is able to be provided
specifically without regard to, and not in reliance upon, the continuance of the
Company's


<PAGE>

obligations under Section 4.01 and the Guarantors' obligations under Article
Ten, then the Company's obligations under such Section 4.01 and the Guarantors'
obligations under Article Ten shall cease upon delivery to the Trustee of such
ruling or Opinion of Counsel and compliance with the other conditions precedent
provided for herein relating to the defeasance contemplated by this Section
8.02.

          After any such irrevocable deposit, the Trustee upon request shall
acknowledge in writing the discharge of the Company's and each Guarantor's
obligations under the Notes and the Note Guarantees, respectively, and this
Indenture except for those surviving obligations in the immediately preceding
paragraph.

          SECTION 8.03. Defeasance of Certain Obligations. The Company (and the
Guarantors) may omit to comply with any term, provision or condition set forth
in clauses (iii) and (iv) of Section 5.01 and Sections 4.03 through 4.16, and
clause (c) of Section 6.01, with respect to such clauses (iii) and (iv) of
Section 5.01, and clause (d) of Section 6.01, with respect to Sections 4.03
through 4.16, and clauses (e) and (f) of Section 6.01 shall be deemed not to be
Events of Default, in each case with respect to the outstanding Notes if:

          (i) the Company has deposited with the Trustee in trust, money and/or
     U.S. Government Obligations that, through the payment of interest and
     principal in respect thereof in accordance with their terms, will provide,
     not later than one day before the due date of any payment referred to in
     this clause (i), money in an amount sufficient in the opinion of a
     nationally recognized firm of independent public accountants expressed in a
     written certification thereof delivered to the Trustee to pay the principal
     of, premium, if any, and accrued interest on the Notes on the Stated
     Maturity of such payments in accordance with the terms of this Indenture
     and the Notes and shall have irrevocably instructed the Trustee to apply
     such money to the payment of such principal, premium and interest;

          (ii) immediately after giving effect to such deposit on a pro forma
     basis, no Event of Default, or event that after the giving of notice or
     lapse of time or both would become an Event of Default, shall have occurred
     and be continuing on the date of such deposit or during the period ending
     on the 123rd day after the date of such deposit, and such deposit shall not
     result in a breach or violation of, or constitute a default under, any
     other agreement or instrument to which the Company, any of its Subsidiaries
     or any Guarantor is a party or by which the Company, the Guarantors, any of
     its Subsidiaries or any Guarantor is bound;

          (iii) the Company has delivered to the Trustee an Opinion of Counsel
     to the effect that (A) the creation of the defeasance trust does not
     violate the Investment Company Act of 1940 and (B) the Holders will not
     recognize income, gain or loss for federal income tax purposes as a result
     of such deposit and defeasance of certain obligations and will be subject
     to federal income tax on the same amount and in the same manner and at the
     same times as would have been the case if such deposit and defeasance had
     not occurred;

          (iv) at such time the Notes are listed on a national securities
     exchange, the Company has delivered to the Trustee an Opinion of Counsel to
     the effect that the Notes will not be delisted as a result of such deposit,
     defeasance and discharge; and

          (v) the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, in each case stating that all conditions
     precedent provided for herein relating to the defeasance contemplated by
     this Section 8.03 have been complied with.


<PAGE>


          SECTION 8.04. Application of Trust Money. Subject to Sections
8.05 and 8.06, the Trustee or Paying Agent shall hold in trust money or U.S.
Government Obligations deposited with it pursuant to Section 8.01, 8.02 or 8.03,
as the case may be, and shall apply the deposited money and the money from U.S.
Government Obligations in accordance with the Notes and this Indenture to the
payment of principal of, premium, if any, and interest on the Notes; but such
money need not be segregated from other funds except to the extent required by
law.

          SECTION 8.05. Repayment to Company. Subject to Sections 7.06, 8.01,
8.02 and 8.03, the Trustee and the Paying Agent shall promptly pay to the
Company upon request set forth in an Officers' Certificate any excess money held
by them at any time and thereupon shall be relieved from all liability with
respect to such money. The Trustee and the Paying Agent shall pay to the Company
upon written request any money held by them for the payment of principal,
premium, if any, or interest that remains unclaimed for two years; provided that
the Trustee or such Paying Agent before being required to make any payment may
cause to be published at the expense of the Company once in a newspaper of
general circulation in the City of New York or mail to each Holder entitled to
such money at such Holder's address (as set forth in the Note Register) notice
that such money remains unclaimed and that after a date specified therein (which
shall be at least 30 days from the date of such publication or mailing) any
unclaimed balance of such money then remaining will be repaid to the Company.
After payment to the Company, Holders entitled to such money must look to the
Company for payment as general creditors unless an applicable law designates
another Person, and all liability of the Trustee and such Paying Agent with
respect to such money shall cease.

          SECTION 8.06. Reinstatement. If the Trustee or Paying Agent is unable
to apply any money or U.S. Government Obligations in accordance with Section
8.01, 8.02 or 8.03, as the case may be, by reason of any legal proceeding or by
reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Company's
and the Guarantors' obligations under this Indenture and the Notes shall be
revived and reinstated as though no deposit had occurred pursuant to Section
8.01, 8.02 or 8.03, as the case may be, until such time as the Trustee or Paying
Agent is permitted to apply all such money or U.S. Government Obligations in
accordance with Section 8.01, 8.02 or 8.03, as the case may be; provided that,
if the Company or the Guarantors have made any payment of principal of, premium,
if any, or interest on any Notes because of the reinstatement of its
obligations, the Company or the Guarantors, as the case may be, shall be
subrogated to the rights of the Holders of such Notes to receive such payment
from the money or U.S. Government Obligations held by the Trustee or Paying
Agent.


                                  ARTICLE NINE
                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

          SECTION 9.01. Without Consent of Holders. The Company and the
Guarantors, when authorized by a resolution of their Board of Directors, and the
Trustee may amend or supplement this Indenture or the Notes without notice to or
the consent of any Holder:

          (1) to cure any ambiguity, defect or inconsistency;

          (2) to comply with Article Five;

          (3) to comply with any requirements of the Commission in connection
     with the qualification of this Indenture under the TIA;


<PAGE>

          (4) to evidence and provide for the acceptance of appointment
     hereunder of a
         successor Trustee;

          (5) to provide for uncertificated Notes in addition to or in place of
     certificated
         Notes;

          (6) to add one or more Subsidiary Guarantees on the terms required by
     this
         Indenture; or

          (7) to make any change that does not adversely affect the rights of
     any Holder in any material respect.

          SECTION 9.02. With Consent of Holders. Subject to Sections 6.04 and
6.07 and without prior notice to the Holders, the Company and the Guarantors,
when authorized by their respective Boards of Directors (as evidenced by a Board
Resolution), and the Trustee may amend this Indenture and the Notes with the
written consent of the Holders of not less than a majority in principal amount
of the Notes then outstanding, and the Holders of not less than a majority in
principal amount of the Notes then outstanding by written notice to the Trustee
may waive future compliance by the Company or the Guarantors with any provision
of this Indenture or the Notes.

          Notwithstanding the provisions of this Section 9.02, without the
consent of each Holder affected, an amendment or waiver, including a waiver
pursuant to Section 6.04, may not:

          (i) change the Stated Maturity of the principal of, or any installment
     of interest on, any Note;

          (ii) reduce the principal of, or premium, if any, or interest on, any
     Note;

          (iii) change the place or currency of payment of principal of, or
     premium, if any, or interest on, any Note;

          (iv) impair the right to institute suit for the enforcement of any
     payment on or after the Stated Maturity (or, in the case of a redemption,
     on or after the Redemption Date) of any Note;

          (v) reduce the above-stated percentage of outstanding Notes the
     consent of whose Holders is necessary to modify or amend this Indenture;

          (vi) waive a default in the payment of principal of, premium, if any,
     or interest on the Notes;

          (vii) reduce the percentage or aggregate principal amount of
     outstanding Notes the consent of whose Holders is necessary for waiver of
     compliance with certain provisions of this Indenture or for waiver of
     certain defaults;

          (viii) release any Guarantor from its Note Guarantee or otherwise
     modify the terms of the Note Guarantees in a material respect adverse to
     the Holders; or

          (ix) modify any of the provisions of this Section 9.02, except to
     increase any such percentage or to provide that certain other provisions of
     this Indenture cannot be modified or waived without the consent of the
     Holder of each outstanding Note affected thereby.


<PAGE>

          It shall not be necessary for the consent of the Holders under
this Section 9.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

          After an amendment, supplement or waiver under this Section 9.02
becomes effective, the Company shall mail to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver. The Company will
mail supplemental indentures to Holders upon request. Any failure of the Company
to mail such notice, or any defect therein, shall not, however, in any way
impair or affect the validity of any such supplemental indenture or waiver.

          SECTION 9.03. Revocation and Effect of Consent. Until an amendment or
waiver becomes effective, a consent to it by a Holder is a continuing consent by
the Holder and every subsequent Holder of a Note or portion of a Note that
evidences the same debt as the Note of the consenting Holder, even if notation
of the consent is not made on any Note. However, any such Holder or subsequent
Holder may revoke the consent as to its Note or portion of its Note. Such
revocation shall be effective only if the Trustee receives the notice of
revocation before the date the amendment, supplement or waiver becomes
effective. An amendment, supplement or waiver shall become effective on receipt
by the Trustee of written consents from the Holders of the requisite percentage
principal amount of the outstanding Notes.

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment,
supplement or waiver. If a record date is fixed, then, notwithstanding the last
two sentences of the immediately preceding paragraph, those persons who were
Holders at such record date (or their duly designated proxies) and only those
persons shall be entitled to consent to such amendment, supplement or waiver or
to revoke any consent previously given, whether or not such persons continue to
be Holders after such record date. No such consent shall be valid or effective
for more than 90 days after such record date.

          After an amendment, supplement or waiver becomes effective, it shall
bind every Holder unless it is of the type described in any of clauses (i)
through (v) of Section 9.02. In case of an amendment or waiver of the type
described in clauses (i) through (v) of Section 9.02, the amendment or waiver
shall bind each Holder who has consented to it and every subsequent Holder of a
Note that evidences the same indebtedness as the Note of the consenting Holder.

          SECTION 9.04. Notation on or Exchange of Notes. If an amendment,
supplement or waiver changes the terms of a Note, the Trustee may require the
Holder to deliver it to the Trustee. The Trustee may place an appropriate
notation on the Note about the changed terms and return it to the Holder and the
Trustee may place an appropriate notation on any Note thereafter authenticated.
Alternatively, if the Company or the Trustee so determines, the Company in
exchange for the Note shall issue and the Trustee shall authenticate a new Note
that reflects the changed terms. Failure to make the appropriate notation or
issue a new Note shall not affect the validity and effect of such amendment,
supplement or waiver.

          SECTION 9.05. Trustee to Sign Amendments, Etc. The Trustee shall be
entitled to receive, and shall be fully protected in relying upon, an Opinion of
Counsel stating that the execution of any amendment, supplement or waiver
authorized pursuant to this Article Nine is authorized or permitted by this
Indenture. Subject to the preceding sentence, the Trustee shall sign such
amendment, supplement or waiver if the same does not adversely affect the rights
of the Trustee. The Trustee may, but shall not be obligated to, execute any such
amendment, supplement or waiver that affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.


<PAGE>

          SECTION 9.06. Conformity with Trust Indenture Act. Every supplemental
indenture executed pursuant to this Article Nine shall conform to the
requirements of the TIA as then in effect.


                                   ARTICLE TEN
                               GUARANTEE OF NOTES

          SECTION 10.01. Note Guarantee. Subject to the provisions of this
Article Ten, each of the Guarantors, as primary obligors and not merely as
sureties, hereby fully, unconditionally and irrevocably guarantees on a senior
basis to each Holder and to the Trustee on behalf of the Holders: (i) the due
and punctual payment of the principal of, premium, if any, on and interest on
each Note, when and as the same shall become due and payable, whether, by
acceleration, required repurchase (including by reason of Change of Control),
call for redemption or otherwise, the due and punctual payment of interest on
the overdue principal of and interest, if any, on the Notes, to the extent
lawful (in each case including interest accruing on or after filing of any
petition in bankruptcy or reorganization relating to the Company or any
Guarantor, whether or not a claim for post filing interest is allowed in such
proceeding), and the due and punctual performance of all other obligations of
the Company to the Holders or the Trustee, all in accordance with the terms of
such Note and this Indenture and (ii) in the case of any extension of time of
payment or renewal of any Note or any of such other obligations, that the same
will be promptly paid in full when due or performed in accordance with the terms
of the extension or renewal, at Stated Maturity, by acceleration, required
repurchase (including by reason of Change of Control), call for redemption or
otherwise. Each of the Guarantors hereby waives diligence, presentment, demand
of payment, filing of claims with a court in the event of merger or bankruptcy
of the Company, any right to require a proceeding first against the Company, the
benefit of discussion, protest or notice with respect to any such Note or the
debt evidenced thereby and all demands whatsoever, and covenants that this Note
Guarantee will not be discharged as to any such Note except by payment in full
of the principal thereof and interest thereon and as provided in Section 8.01
and Section 8.02 (subject to Section 8.06). The obligations of the Guarantors
hereunder shall not be affected by any failure or delay of the Trustee to
exercise any right or remedy under this Indenture, the Notes or this Note
Guarantee. The maturity of the obligations guaranteed hereby may be accelerated
as provided in Article Six for the purposes of this Article Ten. In the event of
any declaration of acceleration of such obligations as provided in Article Six,
such obligations (whether or not due and payable) shall forthwith become due and
payable by the Guarantors for the purpose of this Article Ten. In addition,
without limiting the foregoing provisions, upon the effectiveness of an
acceleration under Article Six, the Trustee shall promptly make a demand for
payment on the Notes under the Note Guarantee provided for in this Article Ten.

          The Note Guarantee shall remain in full force and effect and continue
to be effective should any petition be filed by or against the Company for
liquidation or reorganization, should the Company become insolvent or make an
assignment for the benefit of creditors or should a receiver or trustee be
appointed for all or any significant portion of the Company's assets, and if the
Trustee or the Holder of any Note is required by any court or otherwise to
return to the Company or any Guarantor, or any custodian, receiver, liquidator,
trustee, sequestrator or other similar official acting in relation to the
Company or the Guarantors, any amount paid to the Trustee or such Holder in
respect of a Note, this Note Guarantee, to the extent theretofore discharged,
shall continue to be effective or be reinstated in full force and effect, as the
case may be, all as though such payment has not been made. Each of the
Guarantors further agrees, to the fullest extent that it may lawfully do so,
that, as between the Guarantors, on the one hand, and the Holders and the
Trustee, on the other hand, the maturity of the obligations guaranteed hereby
may be accelerated as provided in Article Six hereof for the purposes of this
Note Guarantee, notwithstanding any stay, injunction or other prohibition extant
under any applicable bankruptcy law preventing such acceleration in respect of
the obligations Guaranteed hereby.


<PAGE>

          Each of the Guarantors hereby irrevocably waives any claim or other
rights which it may now or hereafter acquire against the Company that arise from
the existence, payment, performance or enforcement of its obligations under this
Note Guarantee and this Indenture, including, without limitation, any right of
subrogation, reimbursement, exoneration, contribution, indemnification, any
right to participate in any claim or remedy of the Holders against the Company
or any collateral which any such Holder or the Trustee on behalf of such Holder
hereafter acquires, whether or not such claim, remedy or right arises in equity,
or under contract, statute or common law, including, without limitation, the
right to take or receive from the Company, directly or indirectly, in cash or
other property or by set-off or in any other manner, payment or security on
account of such claim or other rights until such time as the Notes and all of
the Company's other obligations being guaranteed hereby shall have been
indefeasibly paid in full. If any amount shall be paid to the Guarantors in
violation of the preceding sentence and the principal of, premium, if any, and
accrued interest on the Notes shall not have been paid in full, such amount
shall be deemed to have been paid to the Guarantors for the benefit of, and held
in trust for the benefit of, the Holders, and shall forthwith be paid to the
Trustee for the benefit of the Holders to be credited and applied upon the
principal of, premium, if any, and accrued interest on the Notes. Each of the
Guarantors acknowledges that it will receive direct and indirect benefits from
the issuance of the Notes pursuant to this Indenture and that the waivers set
forth in this Section 10.01 are knowingly made in contemplation of such
benefits.

          The Note Guarantee set forth in this Section 10.01 shall not be valid
or become obligatory for any purpose with respect to a Note until the
certificate of authentication on such Note shall have been signed by or on
behalf of the Trustee.

          SECTION 10.02. Obligations Unconditional. Subject to Section 10.05,
nothing contained in this Article Ten or elsewhere in this Indenture or in the
Notes is intended to or shall impair, as among any Guarantor and the Holders,
the obligation of such Guarantor, which is absolute, unconditional and
irrevocable, upon failure by the Company, to pay to the Holders the principal
of, premium, if any, and interest on the Notes as and when the same shall become
due and payable in accordance with their terms, or is intended to or shall
affect the relative rights of the Holders and creditors of such Guarantor, nor
shall anything herein or therein prevent the Holder of any Note or the Trustee
on their behalf from exercising all remedies otherwise permitted by applicable
law upon default under this Indenture.

          Without limiting the foregoing, nothing contained in this Article Ten
will restrict the right of the Trustee or the Holders to take any action to
declare the Note Guarantee to be due and payable prior to the Stated Maturity of
the Notes pursuant to Section 6.02 or to pursue any rights or remedies
hereunder.

          SECTION 10.03. Notice to Trustee. The Guarantors shall give prompt
written notice to the Trustee of any fact known to the Guarantors which would
prohibit the making of any payment to or by the Trustee in respect of the Note
Guarantee pursuant to the provisions of this Article Ten.

          SECTION 10.04. This Article Not to Prevent Events of Default. The
failure to make a payment on account of principal of, premium, if any, or
interest on the Notes by reason of any provision of this Article Ten will not be
construed as preventing the occurrence of an Event of Default.

          SECTION 10.05. Net Worth Limitation. Notwithstanding any other
provision of this Indenture or the Notes, the Note Guarantee shall not be
enforceable against any Guarantor in an amount in excess of the net worth of
such Guarantor at the time that determination of such net worth is, under
applicable law, relevant to the enforceability of the Note Guarantee. Such net
worth shall


<PAGE>

include any claim of any Guarantor against the Company for reimbursement and any
claim against any grantor of a Subsidiary Guarantee for contribution.

          (i) an Officers' Certificate reasonably satisfactory to the Trustee
     stating that, in the opinion of the signers, all conditions precedent, if
     any, provided for in this Indenture relating to the proposed action have
     been complied with; and

          (ii) an Opinion of Counsel reasonably satisfactory to the Trustee
     stating that, in the opinion of such Counsel, all such conditions precedent
     have been complied with.

          SECTION 11.04. Statements Required in Certificate or Opinion.
Each certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture shall include:

          (i) a statement that the person making such certificate or opinion has
     read such covenant or condition;

          (ii) a brief statement as to the nature and scope of the examination
     or investigation upon which the statement or opinion contained in such
     certificate or opinion is based;

          (iii) a statement that, in the opinion of such person, he has made
     such examination or investigation as is necessary to enable him to express
     an informed opinion as to whether or not such covenant or condition has
     been complied with; and

          (iv) a statement as to whether or not, in the opinion of such person,
     such condition or covenant has been complied with, and such other opinions
     as the Trustee may reasonably request; provided, however, that, with
     respect to matters of fact, an Opinion of Counsel may rely on an Officers'
     Certificate or certificates of public officials.

          SECTION 11.05. Acts of Holders. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Holders may be embodied in and evidenced
by one or more instruments of substantially similar tenor signed by such Holders
in person or by an agent duly appointed in writing; and, except as herein
otherwise expressly provided, such action shall become effective when such
instrument or instruments are delivered to the Trustee and, where it is hereby
expressly required, to the Company. Proof of execution of any such instrument or
of a writing appointing any such agent shall be sufficient for any purpose of
this Indenture and conclusive in favor of the Trustee and the Company, if made
in the manner provided in this Section.

          (b) The ownership of Notes shall be proved by the Note Register.

          (c) Any request, demand, authorization, direction, notice, consent,
waiver or other action by the Holder of any Note shall bind every future Holder
of the same Note or the Holder of every Note issued upon the transfer thereof or
in exchange therefor or in lieu thereof, in respect of anything done, suffered
or omitted to be done by the Trustee, any Paying Agent or the Company in
reliance thereon, whether or not notation of such action is made upon such Note.


<PAGE>

          (d) If the Company shall solicit from the Holders any request, demand,
authorization, direction, notice, consent or waiver or other act, the Company
may, at its option, by or pursuant to a Board Resolution, fix in advance a
record date for the determination of such Holders entitled to give such request,
demand, authorization, direction, notice, consent, waiver or other act, but the
Company shall have no obligation to do so. Notwithstanding Trust Indenture Act
Section 316(c), any such record date shall be the record date specified in or
pursuant to such Board Resolution, which shall be a date not more than 30 days
prior to the first solicitation of Holders generally in connection therewith and
no later than the date such solicitation is completed.

          If such a record date is fixed, such request, demand, authorization,
direction, notice, consent, waiver or other act may be given before or after
such record date, but only the Holders of record at the close of business on
such record date shall be deemed to be Holders for purposes of determining
whether Holders of the requisite proportion of Notes then outstanding have
authorized or agreed or consented to such request, demand, authorization,
direction, notice, consent, waiver or other act, and for this purpose the Notes
then outstanding shall be computed as of such record date; provided that no such
request, demand, authorization, direction, notice, consent, waiver or other act
by the Holders on such record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Indenture not later than six
months after the record date.

          SECTION 11.06. Rules by Trustee, Paying Agent or Registrar. The
Trustee may make reasonable rules for action by or at a meeting of Holders. The
Paying Agent or Registrar may make reasonable rules for its functions.

          SECTION 11.07. Payment Date Other Than a Business Day. If an Interest
Payment Date, Redemption Date, Payment Date for an Offer to Purchase, Stated
Maturity or date of maturity of any Note shall not be a Business Day at any
place of payment, then payment of principal of, premium, if any, or interest on
such Note, as the case may be, need not be made on such date, but may be made on
the next succeeding Business Day at such place of payment with the same force
and effect as if made on the Interest Payment Date, Payment Date for an Offer to
Purchase, or Redemption Date, or at the Stated Maturity or date of maturity of
such Note; provided that no interest shall accrue for the period from and after
such Interest Payment Date, Payment Date for an Offer to Purchase, Redemption
Date, Stated Maturity or date of maturity, as the case may be.

          SECTION 11.08. Governing Law. This Indenture and the Notes shall be
governed by and construed in accordance with the internal laws of the State of
New York. The Trustee, the Company, each of the Guarantors and the Holders agree
to submit to the jurisdiction of the courts of the State of New York in any
action or proceeding arising out of or relating to this Indenture or the Notes.

          SECTION 11.09. No Adverse Interpretation of Other Agreements. This
Indenture may not be used to interpret another indenture, loan or debt agreement
of the Company, the Guarantors or any Subsidiary of the Company. Any such
indenture, loan or debt agreement may not be used to interpret this Indenture.

          SECTION 11.10. No Recourse Against Others. No recourse for the payment
of the principal of, premium, if any, or interest on any of the Notes, or for
any claim based thereon or otherwise in respect thereof, and no recourse under
or upon any obligation, covenant or agreement of the Company or the Guarantors
contained in this Indenture, any Guarantee or in any of the Notes, or because of
the creation of any Indebtedness represented thereby, shall be had against any
incorporator or against any past, present or future partner, shareholder, other
equityholder, officer, director, employee or controlling person, as such, of the
Company or of any successor Person, either directly or through the Company or
the Guarantors or any successor Person, whether by virtue of

<PAGE>


any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise; it being expressly understood that all such
liability is hereby expressly waived and released as a condition of, and as a
consideration for, the execution of this Indenture and the issue of the Notes.

          SECTION 11.11. Successors. All agreements of the Company and the
Guarantors in this Indenture and the Notes shall bind its successors. All
agreements of the Trustee in this Indenture shall bind its successor.

          SECTION 11.12. Duplicate Originals. The parties may sign any number of
copies of this Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement.

          SECTION 11.13. Separability. In case any provision in this Indenture
or in the Notes shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

          SECTION 11.14. Table of Contents, Headings, Etc. The Table of
Contents, Cross- Reference Table and headings of the Articles and Sections of
this Indenture have been inserted for convenience of reference only, are not to
be considered a part hereof and shall in no way modify or restrict any of the
terms and provisions hereof.


                                 ARTICLE TWELVE
                               MEETINGS OF HOLDERS

          SECTION 12.01. Purposes for Which Meetings May Be Called. A
meeting of Holders may be called at any time and from time to time pursuant to
the provisions of this Article Twelve for any of the following purposes:

          (a) to give any notice to the Company or to the Trustee, or to give
     any directions to the Trustee, or to waive or to consent to the waiving of
     any Default or Event of Default hereunder and its consequences, or to take
     any other action authorized to be taken by Holders pursuant to any of the
     provisions of Article Six;

          (b) to remove the Trustee or appoint a successor Trustee pursuant to
     the provisions of Article Seven;

          (c) to consent to an amendment, supplement or waiver pursuant to the
     provisions of Section 9.02; or

          (d) to take any other action authorized to be taken by or on behalf of
     the Holders of any specified aggregate principal amount of the Notes under
     any other provision of this Indenture, or authorized or permitted by law.

          SECTION 12.02. Manner of Calling Meetings. The Trustee may at any time
call a meeting of Holders to take any action specified in Section 12.01, to be
held at such time and at such place in The City of New York, New York or
elsewhere as the Trustee will determine. Notice of every meeting of Holders,
setting forth the time and place of such meeting and in general terms the action
proposed to be taken at such meeting, will be mailed by the Trustee, first-class
postage prepaid, to the Company and to the Holders at their last addresses as
they will appear on the


<PAGE>

registration books of the Registrar not less than 10 nor more than 60 days prior
to the date fixed for a meeting.

          Any meeting of Holders will be valid without notice if the Holders of
all outstanding Notes are present in Person or by proxy, or if notice is waived
before or after the meeting by the Holders of all outstanding Notes, and if the
Company and the Trustee are either present by duly authorized representatives or
have, before or after the meeting, waived notice.

          SECTION 12.03. Call of Meetings by the Company or Holders. In case at
any time the Company, pursuant to a Board Resolution, or the Holders of not less
than 10% in aggregate principal amount of the outstanding Notes will have
requested the Trustee to call a meeting of Holders to take any action specified
in Section 12.01, by written request setting forth in reasonable detail the
action proposed to be taken at the meeting, and the Trustee will not have mailed
the notice of such meeting within 20 days after receipt of such request, then
the Company or the Holders of Notes in the amount above specified may determine
the time and place in The City of New York, New York or elsewhere for such
meeting and may call such meeting for the purpose of taking such action, by
mailing or causing to be mailed notice thereof as provided in Section 12.02, or
by causing notice thereof to be published at least once in each of two
successive calendar weeks (on any Business Day during such week) in a newspaper
or newspapers printed in the English language, customarily published at least
five days a week of a general circulation in The City of New York, State of New
York, the first such publication to be not less than 10 nor more than 60 days
prior to the date fixed for the meeting.

          SECTION 12.04. Who May Attend and Vote at Meetings. To be entitled to
vote at any meeting of Holders, a Person will (i) be a registered Holder of one
or more Notes, or (ii) be a Person appointed by an instrument in writing as
proxy for the registered Holder or Holders of Notes. The only Persons who will
be entitled to be present or to speak at any meeting of Holders will be the
Persons entitled to vote at such meeting and their counsel and any
representatives of the Trustee and its counsel and any representatives of the
Company and their counsel.

          SECTION 12.05. Quorum; Action. The Persons entitled to vote a majority
in principal amount of the outstanding Notes shall constitute a quorum. In the
absence of a quorum within 30 minutes of the time appointed for any such
meeting, the meeting shall, if convened at the request of Holders of Notes, be
dissolved. In any other case the meeting may be adjourned for a period of not
less than 10 days as determined by the chairman of the meeting prior to the
adjournment of such meeting. In the absence of a quorum at any such adjourned
meeting, such adjourned meeting may be further adjourned for a period of not
less than 10 days as determined by the chairman of the meeting prior to the
adjournment of such adjourned meeting. Notice of the reconvening of any
adjourned meeting shall be given as provided in Section 12.02, except that such
notice need be given only once and not less than five days prior to the date on
which the meeting is scheduled to be reconvened. Notice of the reconvening of an
adjourned meeting shall state expressly the percentage of the principal amount
of the outstanding Notes which shall constitute a quorum.

          Subject to the foregoing, at the reconvening of any meeting adjourned
for a lack of a quorum, the Persons entitled to vote 25% in principal amount of
the outstanding Notes at the time shall constitute a quorum for the taking of
any action set forth in the notice of the original meeting.

          At a meeting or an adjourned meeting duly reconvened and at which a
quorum is present as aforesaid, any action or matter, except as otherwise
specified herein, shall be effectively passed and decided if passed or decided
by the Persons entitled to vote not less than a majority in principal amount of
outstanding Notes represented and voting at such meeting.


<PAGE>


          Any action or matter passed or decision taken at any meeting
of Holders of Notes duly held in accordance with this Section 12.05 shall be
binding on all the Holders of Notes, whether or not present or represented at
the meeting.

          SECTION 12.06. Regulations May Be Made by Trustee; Conduct of the
Meeting; Voting Rights; Adjournment. Notwithstanding any other provision of this
Indenture, the Trustee may make such reasonable regulations as it may deem
advisable for any action by or any meeting of Holders, in regard to proof of the
holding of Notes and of the appointment of proxies, and in regard to the
appointment and duties of inspectors of votes, and submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it will think appropriate. Such
regulations may fix a record date and time for determining the Holders of record
of Notes entitled to vote at such meeting, in which case those and only those
Persons who are Holders of Notes at the record date and time so fixed, or their
proxies, will be entitled to vote at such meeting whether or not they will be
such Holders at the time of the meeting.

          The Trustee will, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting will have been called by
the Company or by Holders as provided in Section 12.03, in which case the
Company or the Holders calling the meeting, as the case may be, will in like
manner appoint a temporary chairman. A permanent chairman and a permanent
secretary of the meeting will be elected by vote of the Holders of a majority in
principal amount of the Notes represented at the meeting and entitled to vote.

          At any meeting each Holder or proxy will, subject to the
provisions of Section 12.04 hereof, be entitled to one vote for each $1,000
principal amount of Notes held or represented by him or her; provided, however,
that no vote will be cast or counted at any meeting in respect of any Notes
challenged as not outstanding and ruled by the chairman of the meeting to be not
outstanding. The chairman may adjourn any such meeting if he is unable to
determine whether any Holder or proxy will be entitled to vote at such meeting.
The chairman of the meeting will have no right to vote other than by virtue of
Notes held by him or instruments in writing as aforesaid duly designating him as
the proxy to vote on behalf of other Holders. Any meeting of Holders duly called
pursuant to the provisions of Section 12.02 or Section 12.03 may be adjourned
from time to time by vote of the Holders of a majority in aggregate principal
amount of the Notes represented at the meeting and entitled to vote, and the
meeting may be held as so adjourned without further notice.

          SECTION 12.07. Voting at the Meeting and Record to Be Kept.
The vote upon any resolution submitted to any meeting of Holders will be by
written ballots on which will be subscribed the signatures of the Holders of
Notes or/of their representatives by proxy and the principal amount of the Notes
voted by the ballot. The permanent chairman of the meeting will appoint two
inspectors of votes, who will count all votes cast at the meeting for or against
any resolution and will make and file with the secretary of the meeting their
verified written reports in duplicate of all votes cast at the meeting. A record
in duplicate of the proceedings of each meeting of Holders will be prepared by
the secretary of the meeting and there will be attached to such record the
original reports of the inspectors of votes on any vote by ballot taken thereat
and affidavits by one or more Persons having knowledge of the facts, setting
forth a copy of the notice of the meeting and showing that such notice was
mailed as provided in Section 12.02. The record will be signed and verified by
the affidavits of the permanent chairman and the secretary of the meeting and
one of the duplicates will be delivered to the Company and the other to the
Trustee to be preserved by the Trustee, the latter to have attached thereto the
ballots voted at the meeting.

          Any record so signed and verified will be conclusive evidence of the
matters therein
stated.


<PAGE>


          SECTION 12.08. Exercise of Rights of Trustee or Holders May
Not Be Hindered or Delayed by Call of Meeting. Nothing contained in this Article
Twelve will be deemed or construed to authorize or permit, by reason of any call
of a meeting of Holders or any rights expressly or impliedly conferred hereunder
to make such call, any hindrance or delay in the exercise of any right or rights
conferred upon or reserved to the Trustee or to the Holders under any of the
provisions of this Indenture or of the Notes.

          SECTION 12.09. Procedures Not Exclusive. The procedures set forth in
this Article Twelve are not exclusive and the rights and obligations of the
Company, the Trustee and the Holders under other Articles of this Indenture
(including, without limitation, Articles Six, Seven, Eight and Nine) will in no
way be limited by the provisions of this Article Twelve.

preceding the Interest Payment Date) on each Interest Payment Date, commencing
February 1, 1998.

          If (i) the Shelf Registration Statement or Exchange Offer Registration

defined therein) and Deutsche Bank Alex. Brown, then additional interest
("Additional Interest") shall accrue on the principal amount of the Notes, (A)
in the case of (i) above, commencing on the day after either such required
filing date, at a rate of .50% per annum for the first 90 days immediately
following each such filing date, such Additional Interest increasing by an
additional 0.50% per annum at the beginning of each subsequent 90-day period;

effective date, at a rate of .50% per annum for the first 90 days immediately
following each such filing date, such Additional Interest increasing by an

provided that, if there is no existing default in the payment of interest and
this Note is authenticated between a Regular Record Date referred to on the face
hereof and the next succeeding Interest Payment Date, interest shall accrue from
such Interest Payment Date. Interest will be computed on the basis of a 360-day
year of twelve 30-day months.


<PAGE>


          The Company shall pay interest on overdue principal and premium, if
any, and interest on overdue installments of interest, to the extent lawful, at
a rate borne by the Notes.

2.  Method of Payment.

          The Company will pay interest (except defaulted interest) on the
principal amount of the Notes as provided above on each February 1 and August 1
to the persons who are Holders (as reflected in the Note Register at the close
of business on the January 15 and July 15 immediately preceding the Interest
Payment Date), in each case, even if the Note is cancelled on registration of
transfer, registration of exchange, redemption or repurchase after such record
date; provided that, with respect to the payment of principal, the Company will
make payment to the Holder that surrenders this Note to a Paying Agent on or

its option, may pay principal, premium, if any, and interest by its check
payable in such money. It may mail an interest check to a Holder's registered
address (as reflected in the Note Register). If a payment date is a date other

the next succeeding day that is a Business Day and no interest shall accrue for
the intervening period.

1997 (the "Indenture"), between the Company, the Guarantors and First Security
Bank, N.A., as trustee (the "Trustee"). Capitalized terms herein are used as
defined in the Indenture unless otherwise indicated. The terms of the Notes

reference to the Trust Indenture Act. The Notes are subject to all such terms,
and Holders are referred to the Indenture and the Trust Indenture Act for a
statement of all such terms. To the extent permitted by applicable law, in the
event of any inconsistency between the terms of this Note and the terms of the
Indenture, the terms of the Indenture shall control.

          The Notes are unsecured senior obligations of the Company. The Company
may, subject to Article Four of the Indenture, issue additional Notes under the
Indenture.

                  2003     .......................   102.625%

or more sales of its Common Stock, at any time or from time to time in part, at
a Redemption Price (expressed as a percentage of principal amount) of 110.50%,
plus accrued and unpaid interest to the Redemption Date (subject to the rights
of Holders of record on the relevant Regular Record Date that is prior to the
Redemption Date to receive interest due on an Interest Payment Date); provided
that at least $65 million aggregate principal amount of Notes remains
outstanding after each such redemption.

          In the event that more than 98% of the outstanding principal amount of
the Notes are tendered pursuant to an Offer to Purchase, as required by Section
4.11 or Section 4.12, the balance of the Notes will be redeemable, at the
Company's option, in whole or in part, at any time or from time to time
thereafter and prior to maturity, upon not less than 30 nor more than 60 days'
prior notice mailed by first class mail to each Holder's last address as it
appears in the Note Register, at a Redemption Price equal to the price specified
in such Offer to Purchase plus accrued and unpaid interest, if any, to the
Redemption Date (subject to the right of Holders of record on the relevant
Regular Record Date that is on or prior to the Redemption Date to receive
interest due on an Interest Payment Date).

          Notice of any optional redemption will be mailed at least 30 days but
not more than 60 days before the Redemption Date to each Holder of Notes to be
redeemed at his last address as it appears in the Note Register. Notes in
denominations larger than $1,000 may be redeemed in part. On and after the
Redemption Date, interest ceases to accrue on Notes or portions of Notes called
for redemption, unless the Company defaults in the payment of the Redemption
Price.

6.  Repurchase upon a Change of Control.

          Upon the occurrence of any Change of Control, each Holder shall have
the right to require the repurchase of its Notes by the Company in cash pursuant
to the offer described in the Indenture at a purchase price equal to 101% of the
principal amount thereof plus accrued and unpaid interest, if any, to the
Payment Date (the "Change of Control Payment").

          A notice of such Change of Control will be mailed within 30 days after
any Change of Control occurs to each Holder at his last address as it appears in
the Note Register. Notes in denominations larger than $1,000 may be sold to the
Company in part. On and after the Payment Date, interest ceases to accrue on
Notes or portions of Notes surrendered for purchase by the Company, unless the
Company defaults in the payment of the Change of Control Payment.

The Registrar may require a Holder, among other things, to furnish appropriate

law or permitted by the Indenture. The Registrar need not register the transfer

          If money for the payment of principal, premium, if any, or interest
remains unclaimed for two years, the Trustee and the Paying Agent will pay the
money back to the Company at its written request. After that, Holders entitled
to the money must look to the Company for payment, unless an abandoned property
law designates another Person, and all liability of the Trustee and such Paying
Agent with respect to such money shall cease.

10.  Discharge Prior to Redemption or Maturity.

          If the Company deposits with the Trustee money or U.S. Government
Obligations sufficient to pay the then outstanding principal of, premium, if

          SECTION 3. Subsidiary Guarantee. (a) Pursuant to Section 4.07,
Chicago Express, a Restricted Subsidiary of the Company, hereby provides a
Subsidiary Guarantee of payment of the Notes as set forth below.

          (b) Subject to the provisions of this Section 3, Chicago Express, as

irrevocably guarantees on a senior basis to each Holder and to the Trustee on
behalf of the Holders (a "Subsidiary Guarantee"): (i) the due and punctual
payment of the principal of, premium, if any, on and interest on each Note,
when and as the same shall become due and payable, whether, by acceleration,
required repurchase (including by reason of Change of Control), call for

in bankruptcy or reorganization relating to the Company or any Guarantor,


<PAGE>


                                                                             4


whether or not a claim for post filing interest is allowed in such
proceeding), and the due and punctual performance of all other obligations of
the Company to the Holders or the Trustee, all in accordance with the terms of
such Note and the Indenture and (ii) in the case of any extension of time of
payment or renewal of any Note or any of such other obligations, that the same
will be promptly paid in full when due or performed in accordance with the
terms of the extension or renewal, at Stated Maturity, by acceleration,
required repurchase (including by reason of Change of Control), call for
redemption or otherwise. Chicago Express hereby waives diligence, presentment,
demand of payment, filing of claims with a court in the event of merger or
bankruptcy of the Company, any right to require a proceeding first against the
Company, the benefit of discussion, protest or notice with respect to any such
Note or the debt evidenced thereby and all demands whatsoever, and covenants
that this Subsidiary Guarantee will not be discharged as to any such Note
except by payment in full of the principal thereof and interest thereon and as
provided in Section 8.01 and Section 8.02 (subject to Section 8.06) of the
Indenture. The obligations of Chicago Express hereunder shall not be affected
by any failure or delay of the Trustee to exercise any right or remedy under
this First Supplemental Indenture, the Indenture, the Notes or this Subsidiary
Guarantee. The maturity of the obligations guaranteed hereby may be
accelerated as provided in Article Six of the Indenture for the purposes of
this Section 3. In the event of any declaration of acceleration of such
obligations as provided in Article Six of the Indenture, such obligations
(whether or not due and payable) shall forthwith become due and payable by the
Guarantors for the purpose of this Section 3. In addition, without limiting
the foregoing provisions, upon the effectiveness of an acceleration under
Article Six of the Indenture, the Trustee shall promptly make a demand for
payment on the Notes under the Subsidiary Guarantee provided for in this
Section 3.

          The Subsidiary Guarantee shall remain in full force and effect and
continue to be effective should any petition be filed by or against the
Company for liquidation or reorganization, should the Company become insolvent
or make an assignment for the benefit of creditors or should a receiver or
trustee be appointed for all or any significant portion of the Company's
assets, and if the Trustee or the Holder of any Note is required by any court
or otherwise to return to the Company or any Guarantor, or any custodian,
receiver, liquidator, trustee, sequestrator or other similar official acting
in relation to the Company or the Guarantors, any amount paid to the Trustee
or such Holder in respect of a Note, this Subsidiary Guarantee, to the extent



<PAGE>


                                                                             5


theretofore discharged, shall continue to be effective or be reinstated in
full force and effect, as the case may be, all as though such payment has not
been made. Chicago Express further agrees, to the fullest extent that it may
lawfully do so, that, as between the Guarantors, on the one hand, and the
Holders and the Trustee, on the other hand, the maturity of the obligations
guaranteed hereby may be accelerated as provided in Article Six of the
Indenture for the purposes of this Subsidiary Guarantee, notwithstanding any
stay, injunction or other prohibition extant under any applicable bankruptcy
law preventing such acceleration in respect of the obligations Guaranteed
hereby.

          Chicago Express hereby irrevocably waives any claim or other rights
which it may now or hereafter acquire against the Company that arise from the
existence, payment, performance or enforcement of its obligations under this
Subsidiary Guarantee and the Indenture, including, without limitation, any
right of subrogation, reimbursement, exoneration, contribution,
indemnification, any right to participate in any claim or remedy of the
Holders against the Company or any collateral which any such Holder or the
Trustee on behalf of such Holder hereafter acquires, whether or not such
claim, remedy or right arises in equity, or under contract, statute or common
law, including, without limitation, the right to take or receive from the
Company, directly or indirectly, in cash or other property or by set-off or in
any other manner, payment or security on account of such claim or other rights
until such time as the Notes and all of the Company's other obligations being
guaranteed hereby shall have been indefeasibly paid in full. If any amount
shall be paid to the Guarantors in violation of the preceding sentence and the
principal of, premium, if any, and accrued interest on the Notes shall not
have been paid in full, such amount shall be deemed to have been paid to the
Guarantors for the benefit of, and held in trust for the benefit of, the
Holders, and shall forthwith be paid to the Trustee for the benefit of the
Holders to be credited and applied upon the principal of, premium, if any, and
accrued interest on the Notes. Each of the Guarantors acknowledges that it
will receive direct and indirect benefits from the issuance of the Notes
pursuant to the Indenture and that the waivers set forth in this Section 3 are
knowingly made in contemplation of such benefits.

          The Subsidiary Guarantee set forth in this Section 3 shall not be
valid or become obligatory for any purpose with respect to a Note until the
certificate of authentication on such Note shall have been signed by or on
behalf of the Trustee.

                                                                             6


          (c) Subject to Section 3(f), nothing contained in this Section 3 or
elsewhere in the Indenture or in the Notes is intended to or shall impair, as
among any Guarantor and the Holders, the obligation of such Guarantor, which
is absolute, unconditional and irrevocable, upon failure by the Company, to
pay to the Holders the principal of, premium, if any, and interest on the
Notes as and when the same shall become due and payable in accordance with
their terms, or is intended to or shall affect the relative rights of the
Holders and creditors of such Guarantor, nor shall anything herein or therein
prevent the Holder of any Note or the Trustee on their behalf from exercising
all remedies otherwise permitted by applicable law upon default under this
Indenture.

          Without limiting the foregoing, nothing contained in this Section 3
will restrict the right of the Trustee or the Holders to take any action to
declare the Subsidiary Guarantee to be due and payable prior to the Stated
Maturity of the Notes pursuant to Section 6.02 of the Indenture or to pursue
any rights or remedies hereunder.

          (d) Chicago Express shall give prompt written notice to the Trustee
of any fact known to it which would prohibit the making of any payment to or
by the Trustee in respect of the Subsidiary Guarantee pursuant to the
provisions of this Section 3.

          (e) The failure to make a payment on account of principal of,
premium, if any, or interest on the Notes by reason of any provision of this
Section 3 will not be construed as preventing the occurrence of an Event of
Default.

          (f) Notwithstanding any other provision of the Indenture or the
Notes, the Subsidiary Guarantee shall not be enforceable against Chicago
Express in an amount in excess of the net worth of Chicago Express at the time
that determination of such net worth is, under applicable law, relevant to the
enforceability of the Subsidiary Guarantee. Such net worth shall include any
claim of any Subsidy against the Company for reimbursement and any claim
against any grantor of a Subsidiary Guarantee or Note Guarantee for
contribution.

          (g) Notwithstanding any other provision of the Indenture or the
Notes, this Subsidiary Guarantee shall be automatically and unconditionally
released and discharged upon (i) any sale, exchange or transfer, to any Person
not an Affiliate of the Company, of all of the Company's and each Restricted
Subsidiary's Capital Stock in, or all or



<PAGE>


                                                                             7


substantially all the assets of, such Restricted Subsidiary (which sale,
exchange or transfer is not prohibited by the Indenture) or (ii) the release
or discharge of the Guarantee which resulted in the creation of this
Subsidiary Guarantee, except a discharge or release by or as a result of
payment under such Guarantee.

Dear Sirs:

          Amtran, Inc., an Indiana corporation (the "Company"), proposes to
issue and sell to Deutsche Bank Securities Inc. (the "Initial Purchaser")
$75,000,000 aggregate principal amount of its 10.5% Senior Notes due 2004 (the
"Securities") to be issued pursuant to the provisions of an Indenture dated as
of July 24, 1997 (the "Original Indenture") among the Company, as issuer,
American Trans Air, Inc. ("ATA"), Ambassadair Travel Club, Inc., ATA Leisure
Corp. (formerly known as ATA Vacations, Inc.), Amber Travel, Inc., American
Trans Air Training Corporation, American Trans Air Execujet, Inc., Amber Air
Freight Corporation (each, an Indiana corporation) and Chicago Express
Airlines, Inc., a Georgia corporation, as guarantors (together, the
"Guarantors"), and First Security Bank, N.A., as trustee (the "Trustee") as
supplemented by a supplemental indenture dated as of December 21, 1999 (the
"First Supplemental Indenture" and together with the Original Indenture, the
"Indenture") among the Company, the Guarantors and the Trustee. Pursuant to
the terms of the Indenture the Guarantors will guarantee (each, a "Guarantee")
on a joint and several basis the obligations of the Company under the
Securities and the Indenture.

          The Securities will be offered without being registered under the
Securities Act of 1933, as amended (the "Securities Act"), to "qualified
institutional buyers" (as defined in Rule 144A under the Securities Act) in
compliance with the exemption from registration provided by Rule 144A under
the Securities Act ("Rule 144A") and in offshore transactions in reliance on
Regulation S under the Securities Act ("Regulation S").

          The Initial Purchaser and its direct and indirect transferees will
be entitled to the benefits of a registration rights agreement (the
"Registration Rights Agreement"), to be dated the Closing Date (as defined
below) and to be substantially in the form attached hereto as Exhibit A.

          In connection with the sale of the Securities, the Company will
prepare a private placement memorandum (the "Memorandum") setting forth or
including a description of the terms of the Securities, the terms of the
offering and a description of the Company and its business. Any reference
herein to the Memorandum shall be deemed to refer to and include the documents
incorporated by reference therein which were filed under the Securities
Exchange Act of 1934, as amended (the "Exchange Act") on or before the date of
the Memorandum; and any reference herein to the terms "amend", "amendment" or
"supplement" with respect to the Memorandum shall be deemed to refer to and
include the filing of any document under the Exchange Act after the date of
the Memorandum, deemed to be incorporated therein by reference.

     1.   Representations and Warranties. Each of the Guarantors and the
Company represents and warrants to, and agrees with, the Initial Purchaser
that as of the date hereof:

          (a) The Memorandum, in the form used by the Initial Purchaser to
confirm sales and on the Closing Date (as defined below), will not contain any
untrue statement of a material fact or omit to state a material fact necessary
to make the statements therein, in the light of the circumstances under which
they were made, not misleading, except that the representations and warranties
set forth in this Section 1(a) do not apply to statements or omissions in the
Memorandum based upon information relating to the Initial Purchaser furnished
to the Company or any Guarantor in writing by the Initial Purchaser expressly
for use therein.

          (b) None of the Guarantors, the Company nor any affiliate (as
defined in Rule 501(b) of Regulation D under the Securities Act, an

agent, (i) sold, offered for sale, solicited offers to buy or otherwise
negotiated in respect of, any security (as defined in the Securities Act)
which is or will be integrated with the sale of the Securities in a manner
that would require the registration under the Securities Act of the Securities
or (ii) engaged in any form of general solicitation or general advertising in
connection with the offering of the Securities (as those terms are used in
Regulation D under the Securities Act) or in any manner involving a public
offering within the meaning of Section 4(2) of the Securities Act except that
no representation is made as to the activities of the Initial Purchaser.

          (c) None of the Guarantors, the Company, their Affiliates nor any
person acting on its or their behalf (other than the Initial Purchaser) has
engaged in any directed selling efforts (as that term is defined in Regulation
S) with respect to the Securities and each of the Guarantors, the Company and
its Affiliates and any person acting on its or their behalf (other than the
Initial Purchaser) have complied with the offering restrictions requirement of
Regulation S.

          (d) The Company is subject to Section 13 or 15(d) of the Securities
Exchange Act of 1934, as amended.

          (e) Assuming the accuracy of the representations and warranties of

will be required to register as an

or other), business, prospects or results of operations of the Company and the
Guarantors, taken as a whole (a "Material Adverse Effect").

          (l) The Securities have been duly authorized and, when executed,
authenticated and delivered to and paid for by the Initial Purchaser in
accordance with the terms of this Agreement, will be (x) valid and binding
obligations of the Company enforceable in accordance with their terms, except

contemplated by the Memorandum.

          (t) The Company and each of the Guarantors possess adequate
certificates, authorities and permits issued by appropriate governmental
agencies or bodies necessary to conduct, in all material respects, the
business now operated by them and have not received any notice of proceedings
relating to the revocation or modification of any such certificate, authority
or permit that reasonably would be likely to, individually or in the
aggregate, have a Material Adverse Effect.

          (u) Except as disclosed in the Memorandum, no labor dispute with the

human health and safety, the environment or hazardous or toxic substances or

all permits, licenses or other approvals required of them under applicable
Environmental Laws to conduct their respective businesses and (iii) are in
compliance with all terms and conditions of any such permit, license or
approval, except where such noncompliance with Environmental Laws, failure to
receive required permits, licenses or other approvals or failure to comply
with the terms and conditions of such permits, licenses or approvals would
not, singly or in the aggregate, have a Material Adverse Effect.

          (w) Except as disclosed in the Memorandum, each of the Guarantors

other properties and assets owned by them, in each case free from liens,
encumbrances and defects except where the failure to have such title would not

date-sensitive functions involving certain dates prior to and any dates after
December 31, 1999 (the "Year 2000 Problem"), and has determined that such risk

a Material Adverse Effect; and the Company believes, after due inquiry, that
each supplier, vendor, customer or financial service organization used or
serviced by the Company and its subsidiaries has remedied or will remedy on a
timely basis the Year 2000 Problem, except to the extent that a failure to
remedy by any such supplier, vendor, customer or financial service
organization would not have a Material Adverse Effect.

          The representations and warranties contained in this Agreement shall
be true and correct as of the date of this Agreement and as of the Closing
Date.

     2.   Offering. The Initial Purchaser has advised the Company and the
Guarantors that it will make an offering of the Securities received and paid
for by the Initial Purchaser hereunder on the terms set forth in the
Memorandum as soon as practicable after this Agreement is entered into as in
the Initial Purchaser's judgment is advisable.

     3.   Issuance and Delivery.

          (a) The Company hereby agrees to sell to the Initial Purchaser, and
the Initial Purchaser, upon the basis of the representations and warranties
herein contained, but subject to the conditions hereinafter stated, agrees to

upon by the Company and the Initial Purchaser. The time and date of such
payment are herein referred to as the Closing Date. Delivery of the Securities

any transfer taxes payable in connection with the transfer of the Securities

     notice have been given of any intended or potential downgrading or of any
     review for a possible change that does not indicate the direction of the
     possible change, in the rating accorded any securities of any of the
     Guarantors or the Company by any "nationally recognized statistical
     rating organization," as such term is defined for purposes of Rule

     involving a prospective change, in the condition, financial or otherwise,
     or in the earnings, business or operations, of the Company and the
     Guarantors, taken as a whole, from that set forth in the Memorandum that,
     in the Initial Purchaser's judgment, is material and adverse and that
     makes it, in the Initial Purchaser's judgment, impracticable to market
     the Securities on the terms and in the manner contemplated in the
     Memorandum.

          (b) The Initial Purchaser shall have received on the Closing Date

of the Company and (ii) a certificate, dated the Closing Date and signed by an
executive officer of each Guarantor, in each case, to the effect set forth in

of the Company and the Guarantors contained in this Agreement are true and
correct as of the Closing Date and that the Company and each of the Guarantors
have complied with all of the agreements and satisfied all of the condit ions
on their part to be performed or satisfied on or before the Closing Date. The
officers signing and delivering such certificates may rely upon the best of
their knowledge as to proceedings threatened.

statements and information of the type ordinarily included in accountants'
"comfort letters" to underwriters with respect to the financial statements and
certain financial information contained in the Memorandum;


<PAGE>


                                                                             8

          (g) Each of the Guarantors and the Company shall have furnished to
the Initial Purchaser and to counsel for the Initial Purchaser, in form and
substance satisfactory to it and to them, such other documents, certificates
and opinions as such counsel may reasonably request in order to pass upon the
matters referred to in Section 4(e) and in order to evidence the accuracy and
completeness of any of the representations, warranties or statements, the
performance of any covenant by any of the Guarantors or the Company
theretofore to be performed, or the compliance with any of the conditions
herein contained.

          5. Covenants of the Company. In further consideration of the
agreements of the Initial Purchaser contained in this Agreement, the Company
and each of the Guarantors covenant as follows:

          (a) To furnish to the Initial Purchaser, without charge, during the
period mentioned in paragraph (c) below, as many copies of the Memorandum and
any supplements and amendments thereto as it may reasonably request and to

the Initial Purchaser a copy of each such proposed amendment or supplement and
not to use any such proposed amendment or supplement to which the Initial
Purchaser reasonably objects.

          (c) If, during such period after the date hereof and prior to the
date on which all of the Securities shall have been sold by the Initial
Purchaser, any event shall occur or condition exist as a result of which it is
necessary in the Initial Purchaser's judgment to amend or supplement the
Memorandum in order to make the statements therein, in the light of the
circumstances when the Memorandum is delivered to a purchaser, not misleading,
or if, with the opinion of counsel to the Initial Purchaser it is necessary to
amend or supplement the Memorandum to comply with applicable law, forthwith to
prepare and furnish, at its own expense, to the Initial Purchaser, either
amendments or supplements to the Memorandum so that the statements in the
Memorandum as so amended or supplemented will not, in the light of the
circumstances when the Memorandum is delivered to a purchaser, be misleading
or so that the Memorandum, as so amended or supplemented, will comply with
applicable law.

          (d) So long as any of the Securities are "restricted securities"
within the meaning of Rule 144(a)(3) under the Securities Act, at any time
when the Company is not subject to Section 13 or 15(d) of the Exchange Act,
each of the Guarantors and the Company will provide to any holder of such
restricted securities, or to any prospective purchaser of such restricted
securities designated by a holder, upon the request of such holder or
prospective purchaser, any information required to be delivered to holders and
prospective purchasers of the Securities pursuant to Rule 144A(d)(4) under the
Securities Act.

                                                                            9

the Commission, and such other documents, reports and information as shall be

          (g) During the period of two years after the Closing Date, each of

the Guarantors or the Company will be or become an open-end investment
company, unit investment trust or face-amount certificate company that is or
is required to be registered under Section 8 of the Investment Company Act, or
a closed-end investment company required to be registered, but not registered,
under the Investment Company Act.

          (j) The Company shall bear and pay all costs and expenses incurred
incident to the performance of its obligations under this Agreement, whether
or not the transactions contemplated herein are consummated or this Agreement

<PAGE>


                                                                            10

purchase, either alone or with one or more other persons, for any account in
which they or any of their affiliates have a beneficial interest in any
Securities, and neither they nor any of their affiliates will make bids or
purchases for the purpose of creating actual, or apparent, active trading in,
or of raising the price of, the Securities, in either case in violation of
Regulation M under the Exchange Act.

          (l) Between the date of this Agreement and the Closing Date, none of
the Guarantors or the Company will without the Initial Purchaser's prior
written consent offer, sell, or enter into any agreement to sell, any public
debt securities registered under the Securities Act or any debt securities
which may be resold in a transaction exempt from the registration requirements
of the Securities Act in reliance on Rule 144A thereunder and which are
marketed through the use of a disclosure document containing substantially the
same information as a prospectus for similar debt securities registered under
the Securities Act (other than the Securities).

          (m) Not to solicit any offer to buy or offer or sell the Securities
by means of any form of general solicitation or general advertising (as those
terms are used in Regulation D under the Securities Act) or in any manner
involving a public offering within the meaning of Section 4(2) of the
Securities Act.

          (n) If requested by the Initial Purchaser, to use its reasonable
efforts to permit the Securities to be designated PORTAL securities in
accordance with the rules and regulations adopted by the National Association
of Securities Dealers, Inc. relating to trading in the PORTAL Market.

          (o) None of the Company, the Guarantors, their Affiliates or any
person acting on its or their behalf (other than the Initial Purchaser) will
engage in any directed selling efforts (as that term is defined in Regulation
S) with respect to the Securities, and the Company, each of the Guarantors and
their Affiliates and each person acting on its or their behalf (other than the
Initial Purchaser) will comply with the offering restrictions of Regulation S.

          (p) Neither the Company, any Guarantor nor any Affiliate will sell,
offer for sale or solicit offers to buy or otherwise negotiate in respect of
any security (as defined in the Securities Act) which could be integrated with
the sale of the Securities in a manner which would require the registration
under the Securities Act.

     6.   Offering of Securities; Restrictions on Transfer.

          (a) The Initial Purchaser represents and warrants that it is a
qualified institutional buyer as defined in Rule 144A under the Securities Act
(a "QIB"). The Initial Purchaser agrees with the Company that (i) it has not
and will not solicit offers for, and has not offered or sold and will not
offer or sell, such Securities by any form of general solicitation or general
advertising (as those terms are used in Regulation D under the Securities Act)
or in any manner involving a public offering within the meaning of Section
4(2) of the Securities Act and (ii) it has and will solicit offers for such
Securities only from, and has offered and will offer such Securities only to,
persons that it reasonably believes to be (A) in the case of offers inside the
United States, QIBs and (B) in the case of offers outside the United States,
to persons other than U.S. persons ("foreign purchasers," which term shall
include dealers or other professional fiduciaries in the United States acting
on a discretionary basis for foreign beneficial owners (other

                                                                            11

than an estate or trust)) that, in each case, in purchasing such Securities
are deemed to have represented and agreed as provided in the Memorandum under
the caption "Transfer Restrictions."

          (b) The Initial Purchaser represents, warrants, and agrees with
respect to offers and sales outside the United States that:

          (i) it understands that no action has been or will be taken in any
     jurisdiction by any Guarantor or the Company that would permit a public
     offering of the Securities, or possession or distribution of the
     Memorandum or any other offering or publicity material relating to the
     Securities, in any country or jurisdiction where action for that purpose
     is required;

          (ii) such Initial Purchaser will comply with all applicable laws and
     regulations in each jurisdiction in which it acquires, offers, sells or
     delivers Securities or has in its possession or distributes the
     Memorandum or any such other material, in all cases at its own expense;

          (iii) the Securities have not been and will not be registered under
     the Securities Act and may not be offered or sold within the United
     States or to, or for the account or benefit of, U.S. persons except in
     accordance with Regulation S or pursuant to an exemption from the
     registration requirements of the Securities Act;

          (iv) the Initial Purchaser has offered the Securities and will offer
     and sell the Securities (A) as part of their distribution at any time and
     (B) otherwise until 40 days after the later of the commencement of the
     offering of the Securities and the Closing Date, only in accordance with
     Rule 903 of Regulation S or another exemption from the registration
     requirements of the Securities Act. Accordingly, neither the Initial
     Purchaser, its Affiliates nor any persons acting on its or their behalf
     have engaged or will engage in any directed selling efforts (within the
     meaning of Regulation S) with respect to the Securities, and the Initial
     Purchaser, its Affiliates and any such persons have complied and will
     comply with the offering restrictions requirements of Regulation S;

          (v) the Initial Purchaser represents that it has (i) not offered or
     sold, and will not offer or sell, in the United Kingdom, by means of any
     document, any Securities other than to persons whose ordinary business it
     is to buy or sell shares or debentures, whether as principal or as agent
     (except in circumstances which do not constitute an offer to the public
     within the meaning of the Companies Act 1989 of Great Britain); (ii)
     complied and will comply with all applicable provisions of the Financial
     Services Act 1986 of the United Kingdom with respect to anything done by
     it in relation to the Securities in, from or otherwise involving the
     United Kingdom; and (iii) only issued or passed on and will only issue or
     pass on in the United Kingdom any document received by it in connection
     with the issue of the Securities to a person who is of a kind described
     in Article 9(3) of the Financial Services Act 1986 (Investment
     Advertisements) (Exemptions) Order 1996 or is a person to whom the
     document may otherwise lawfully be issued or passed on;


<PAGE>


                                                                            12



          (vi) the Initial Purchaser understands that the Securities have not
     been and will not be registered under the Securities and Exchange Law of
     Japan, and represents that it has not offered or sold, and agrees that it
     will not offer or sell, any Securities, directly or indirectly in Japan
     or to any resident of Japan except (A) pursuant to an exemption from the
     registration requirements of the Securities and Exchange Law of Japan and
     (B) in compliance with any other applicable requirements of Japanese law;
     and

          (vii) the Initial Purchaser agrees that, at or prior to confirmation
     of sales of the Securities, it will have sent to each distributor, dealer
     or person receiving a selling concession, fee or other remuneration that
     purchases Securities from it during the restricted period a confirmation
     or notice to substantially the following effect:

          "The Securities covered hereby have not been registered under the
          U.S. Securities Act of 1933 (the "Securities Act") and may not be
          offered and sold within the United States or to, or for the account
          or benefit of, U.S. persons (i) as part of their distribution at any
          time or (ii) otherwise until 40 days after the later of the
          commencement of the offering and the closing date, except in either
          case in accordance with Regulation S (or Rule 144A if available)
          under the Securities Act. Terms used above have the meanings given
          to them by Regulation S."

Terms used in this Section 6 have the meaning given to them by Regulation S of
the Securities Act.

     7.   Indemnification and Contribution.

          (a) Each of the Company and each Guarantor, jointly and severally,
agrees to indemnify and hold harmless the Initial Purchaser, and each person,
if any, who controls the Initial Purchaser within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act, or is
under common control with, or is controlled by, the Initial Purchaser, from
and against any and all losses, claims, damages and liabilities (including,
without limitation, any legal or other expenses reasonably incurred by the
Initial Purchaser or any such controlling of affiliated person in connection
with defending or investigating any such action or claim) caused by any untrue
statement or alleged untrue statement of a material fact contained in the
Memorandum (as amended or supplemented if the Company shall have furnished any
amendments or supplements thereto), or caused by any omission or alleged
omission to state therein a material fact necessary to make the statements
therein in light of the circumstances under which they were made not
misleading, except insofar as such losses, claims, damages or liabilities are
caused by any such untrue statement or omission or alleged untrue statement or
omission based upon information relating to the Initial Purchaser furnished to
any Guarantor or the Company in writing by the Initial Purchaser expressly for
use therein.

          (b) The Initial Purchaser agrees to indemnify and hold harmless each
Guarantor and the Company, their directors, their officers and each person, if
any, who controls the Company or any Guarantor within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act to the same
extent as the foregoing indemnity from each Guarantor and the Company to the
Initial Purchaser, but only with reference to information relating to the
Initial Purchaser furnished to any Guarantor or


<PAGE>


                                                                            13


the Company in writing by the Initial Purchaser expressly for use in the
Memorandum or any amendments or supplements thereto.

          (c) In case any proceeding (including any governmental
investigation) shall be instituted involving any person in respect of which
indemnity may be sought pursuant to either paragraph (a) or (b) above, such
person (the "indemnified party") shall promptly notify the person against whom
such indemnity may be sought (the "indemnifying party") in writing and the
indemnifying party, upon request of the indemnified party, shall retain
counsel reasonably satisfactory to the indemnified party to represent the
indemnified party and any others the indemnifying party may designate in such
proceeding and shall pay the fees and disbursements of such counsel related to
such proceeding. In any such proceeding, any indemnified party shall have the
right to retain its own counsel, but the fees and expenses of such counsel
shall be at the expense of such indemnified party unless (i) the indemnifying
party and the indemnified party shall have mutually agreed to the retention of
such counsel or (ii) the named parties to any such proceeding (including any
impleaded parties) include both the indemnifying party and the indemnified
party and representation of both parties by the same counsel would be
inappropriate due to actual or potential differing interests between them. It
is understood that the indemnifying party shall not, in connection with any
proceeding or related proceedings in the same jurisdiction, be liable for the
fees and expenses of more than one separate firm (in addition to any local
counsel) for all such indemnified parties and that all such fees and expenses
shall be reimbursed as they are incurred. Such firm shall be designated in
writing by the Initial Purchaser, in the case of parties indemnified pursuant
to paragraph (a) above, and by the Guarantors and the Company in the case of
parties indemnified pursuant to paragraph (b) above. The indemnifying party
shall not be liable for any settlement of any proceeding effected without its
written consent, but if settled with such consent or if there be a final
judgment for the plaintiff, the indemnifying party agrees to indemnify the
indemnified party from and against any loss or liability by reason of such
settlement or judgment. Notwithstanding the foregoing sentence, if at any time
an indemnified party shall have requested an indemnifying party to reimburse
the indemnified party for fees and expenses f counsel as contemplated by the
second and third sentences of this paragraph, the indemnifying party agrees
that it shall be liable for any settlement of any proceeding effected without
its written consent if (i) such settlement is entered into more than 30 days
after receipt by such indemnifying party of the aforesaid request and (ii)
such indemnifying party shall not have reimbursed the indemnified party in
accordance with such request prior to the date of such settlement. No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement of any pending or threatened proceeding in
respect of which any indemnified party is or could have been a party and
indemnity could have been sought hereunder by such indemnified party, unless
such settlement includes an unconditional release of such indemnified party
from all liability on claims that are the subject matter of such proceeding.

          (d) To the extent the indemnification provided for in paragraph (a)
or (b) of this Section 7 is unavailable to an indemnified party or
insufficient in respect of any losses, claims, damages or liabilities, then
each indemnifying party under such paragraph, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable
by such indemnified party as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Guarantors and the Company, on the one hand, and the
Initial Purchaser, on the other hand, from the offering of such Securities or
(ii) if the allocation



<PAGE>


                                                                            14

provided by clause (i) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Guarantors
and the Company on the one hand and the Initial Purchaser on the other hand in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative benefits received by the Guarantors and the
Company on the one hand and the Initial Purchaser on the other hand in
connection with the offering of such Securities shall be deemed to be in the
same respective proportions as the net proceeds from the offering of such
Securities (before deducting expenses) received by the Guarantors and the
Company and the total discounts and commissions received by the Initial
Purchaser in respect thereof bear to the aggregate offering price of such
Securities. The relative fault of the Guarantors and the Company on the one
hand and of the Initial Purchaser on the other hand shall be determined by
reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by any Guarantor or the Company
or by the Initial Purcaser and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or
omission.

          (e) The Guarantors, the Company and the Initial Purchaser agree that
it would not be just or equitable if contribution pursuant to this Section 7
were determined by pro rata allocation or by any other method of allocation
that does not take account of the equitable considerations referred to in
paragraph (d) above. The amount paid or payable by an indemnified party as a
result of the losses, claims, damages and liabilities referred to in paragraph
(d) above shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 7, the Initial Purchaser shall
not be required to contribute any amount in excess of the amount by which the
total price at which the Securities resold by it in the initial placement of
such Securities were offered to investors exceeds the amount of any damages
that the Initial Purchaser has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

          (f) The indemnity and contribution provisions contained in this
Section 7 and the representations and warranties of the Guarantors and the
Company contained in this Agreement shall remain operative and in full force
and effect regardless of (i) termination of this Agreement, (ii) any

                              Form of Opinion of
                            Cravath, Swaine & Moore

               (i) No authorization, approval or other action by, and no
          notice to, consent of, order of, or filing with, any United States
          Federal, New York or, to the extent required under the General
          Corporation Law of the State of Delaware, governmental authority or
          regulatory body is required for the consummation of the transactions
          contemplated by the Purchase Agreement, except such as may be
          required under the blue sky laws of any jurisdiction in connection
          with the purchase and distribution of the Securities by the Initial
          Purchaser;

               (ii) (A) The statements in the Memorandum under the caption
          "Description of the Notes," insofar as such statements purport to
          summarize provisions of the Securities, fairly summarize such
          provisions, and (B) the statements in the Memorandum under the
          caption "Certain United States Federal Income Tax Consequences,"
          insofar as they purport to describe the material tax consequences of
          an investment in the Securities, fairly summarize the matters
          therein described;

               (iii) Assuming (i) the accuracy of the representations and
          warranties of the Company, each of the Guarantors and the Initial
          Purchaser set forth in the Purchase Agreement, (ii) the due
          performance by the Company, each of the Guarantors and the Initial
          Purchaser, of the covenants and agreements set forth in the Purchase
          Agreement, (iii) the Initial Purchaser's compliance with the
          offering and transfer procedures and restrictions described in the
          Memorandum and (iv) the accuracy of the representations and
          warranties made in accordance with the Purchase Agreement and the
          Memorandum by purchasers to whom the Initial Purchaser initially
          resells the Securities, the offer, sale and delivery of the
          Securities to the Initial Purchaser in the manner contemplated by
          the Purchase Agreement and the Memorandum and the initial resale of
          the Securities by the Initial Purchaser in the manner contemplated
          in the Memorandum and the Purchase Agreement, do not require
          registration under the Securities Act of 1933, as amended, it being
          understood that no opinion is expressed as to any subsequent resale
          of any Securities;

               (iv) Neither the Company nor any of the Guarantors is required
          to register as an "investment company" and, after giving effect to
          the offer, issuance and delivery of the Securities in accordance
          with the terms of the Purchase Agreement and the application of the
          proceeds thereof as described in the Memorandum, neither the Company
          nor any of the Guarantors will be required to register as an
          "investment Company" under the Investment Company Act of 1940, as
          amended;

               (v) Each of the Original Indenture, the First Supplemental
          Indenture and the Registration Rights Agreement constitute legal,
          valid and binding obligations of the Company and each Guarantor,
          enforceable against the Company and each Guarantor in accordance
          with their terms (subject to applicable bankruptcy, insolvency,
          fraudulent transfer, reorganization, moratorium or other similar
          laws affecting creditors'

                                                                             2

          rights generally from time to time in effect and to general
          principles of equity, including, without limitation, concepts of
          materiality, reasonableness, good faith and fair dealing, regardless
          of whether such enforceability is considered in a proceeding in
          equity or at law);

               (vi) The Securities when executed, issued and authenticated in
          accordance with the provisions of the Indenture and delivered to the
          Initial Purchaser against payment therefor in accordance with the
          provisions of the Purchase Agreement, will be legal, valid and
          binding obligations of the Company, enforceable against the Company
          in accordance with their terms and entitled to the benefits of the
          Indenture (subject to applicable bankruptcy, insolvency, fraudulent
          transfer, reorganization, moratorium or other laws affecting
          creditors' rights generally from time to time in effect and to
          general principles of equity, including, without limitation,
          concepts of materiality, reasonableness, good faith and fair
          dealing, regardless of whether such enforceability is considered in
          a proceeding in equity or at law); in expressing the opinion set
          forth in this paragraph (vi), such counsel may assume, with the
          consent of the Initial Purchaser, that the form of the Securities
          will conform to that included in the Indenture; and

               (vii) Upon execution and delivery of the First Supplemental
          Indenture by the Guarantors and the Company, the Guarantees will be
          legal, valid and binding obligations of each of the Guarantors,
          enforceable against each of the Guarantors in accordance with their
          terms and entitled to the benefits of the Indenture (subject to
          applicable bankruptcy, insolvency, fraudulent transfer,
          reorganization, moratorium or other laws affecting creditors' rights
          generally from time to time in effect and to general principles of
          equity, including, without limitation, concepts of materiality,
          reasonableness, good faith and fair dealing, regardless of whether
          such enforceability is considered in a proceeding in equity or at
          law);

and to such further effect with respect to other legal matters relating to the
Purchase Agreement and the sale of the Securities thereunder as counsel for
the Initial Purchaser may reasonably request.

          Such opinion shall also state that, in connection with the
preparation of the Memorandum, such counsel has participated in conferences
with certain officers of, and with the accountants and counsel for, the
Guarantors and the Company concerning the preparation of the Memorandum. Such
opinion may state that although such counsel has made certain inquiries and
investigations in connection with the preparation of the Memorandum, the
limitations inherent in the role of outside counsel are such that such counsel
does not assume responsibility for the accuracy or completeness of the
statements made in the Memorandum, except insofar as the statements relate to
such counsel and except to the extent set forth in paragraph (ii) of such
counsel's opinion dated the date hereof. Subject to the foregoing, such
opinion shall state that such counsel advises the Initial Purchaser that their
work in connection with this matter did not disclose any information that gave
such counsel reason to believe that the Memorandum (except the financial
statements and other information of a statistical, accounting or financial
nature included or incorporated by reference therein, as to which such counsel
does not express any view) as of its date or the date hereof, included or
includes an

                    Form of Opinion of the General Counsel
                       of the Guarantors and the Company

               (i) Each of the Guarantors and the Company is a corporation
          duly incorporated, validly existing and in good standing under the
          laws of the jurisdiction in which it is incorporated, with corporate
          power and authority under such laws to own, lease and operate its
          properties and conduct its business as described in the Memorandum
          and to perform its obligations under the Purchase Agreement, the
          Registration Rights Agreement, the Securities (with respect to the
          Company), the Guarantees (with respect to the Guarantors), and the
          Indenture;

               (ii) Each of the Guarantors and the Company are duly qualified
          to transact business as a foreign corporation and are in good
          standing in each other jurisdiction in which they own or lease
          property of a nature, or transact business of a type, that would
          make such qualification necessary, except to the extent that the
          failure to so qualify or be in good standing would not have a
          Material Adverse Effect;

               (iii) ATA is a "citizen of the United States" (as defined in

          the name of such Holder, the principal amount of Registrable
          Securities delivered for exchange and a statement that such Holder
          is withdrawing his election to have such Securities exchanged.

               As soon as practicable after the last Exchange Date, the
Company shall:

               (i) accept for exchange Registrable Securities or portions
          thereof tendered and not validly withdrawn pursuant to the Exchange
          Offer; and

               (ii) deliver, or cause to be delivered, to the Trustee for

          Exchange Security equal in principal amount to the principal amount
          of the Registrable Securities surrendered by such Holder.

          The Company and the Subsidiary Guarantors shall use their best
efforts, at their cost, to complete the Exchange Offer as provided above and
shall comply with the applicable requirements of the 1933 Act, the 1934 Act
and other applicable laws and regulations in connection with the Exchange
Offer. The Exchange Offer shall not be subject to any conditions, other than
that the Exchange Offer does not violate applicable law or any applicable
interpretation of the Staff of the SEC. The Company shall inform the Initial
Purchaser of the names and addresses of the Holders to whom the Exchange Offer
is made, and the Initial Purchaser shall have the right, subject to applicable
law, to contact such Holders and otherwise facilitate the tender of
Registrable Securities in the Exchange Offer.

          (b) In the event that (i) the Company and the Subsidiary Guarantors
determine that the Exchange Offer Registration provided for in Section 2(a)
above is not available or may not be consummated as soon as practicable after
the last Exchange Date because it would violate applicable law or the
applicable interpretations of the Staff of the SEC, (ii) the Exchange Offer is
not for any other reason consummated by June 21, 2000 or (iii) the Exchange
Offer has been completed and in the opinion of counsel for the Initial
Purchaser a Registration Statement must be filed and a Prospectus must be
delivered by the Initial Purchaser in connection with any offering or sale of
Registrable Securities, the Company and the Subsidiary Guarantors shall use

<PAGE>


their best efforts, at their cost, to cause to be filed as soon as practicable
after such determination, date or notice of such opinion of counsel is given
to the Company, as the case may be, a Shelf Registration Statement providing
for the sale by the Holders of all of the Registrable Securities and to have
such Shelf Registration Statement declared effective by the SEC within 60 days
after the date such Shelf Registration Statement was filed. The Company and
the Subsidiary Guarantors agree to use their best efforts to keep the Shelf
Registration Statement continuously effective until the second anniversary of
its effective date or such shorter period that will terminate when all of the
Registrable Securities covered by the Shelf Registration Statement have been
sold pursuant to the Shelf Registration Statement. Notwithstanding the
foregoing, during any consecutive 365- day period, the Company will have the
ability to suspend the availability of the Shelf Registration Statement for up
to two periods of up to 30 consecutive days each (except that none of such
periods may occur during the 60-day period immediately prior to the maturity
of the Securities) if the Company's Board of Directors determines in good
faith that there is a valid purpose for the suspension. The Company and the
Subsidiary Guarantors further agree to supplement or amend the Shelf
Registration Statement if required by the rules, regulations or instructions
applicable to the registration form used by the Company and the Subsidiary
Guarantors for such Shelf Registration Statement or by the 1933 Act or by any
other rules and regulations thereunder for shelf registration or if reasonably
requested by a Holder with respect to information relating to such Holder, and
to use their best efforts to cause any such amendment to become effective and
such Shelf Registration Statement to become usable as soon as thereafter
practicable. The Company and the Subsidiary Guarantors agree to furnish to the
Holders of Registrable Securities copies of any such supplement or amendment
promptly after its being used or filed with the SEC.

          (c) The Company and the Subsidiary Guarantors shall pay all
Registration Expenses in connection with the registration pursuant to Section
2(a) or Section 2(b). Each Holder shall pay all underwriting discounts and
commissions and transfer taxes, if any, relating to the sale or disposition of
such Holder's Registrable Securities pursuant to the Shelf Registration
Statement.

          (d) An Exchange Offer Registration Statement pursuant to Section
2(a) hereof or a Shelf Registration Statement pursuant to Section 2(b) hereof
will not be deemed to have become effective unless it has been declared
effective by the SEC; provided, however, that, if, after it has been declared
effective, the offering of Registrable Securities pursuant to a Shelf
Registration Statement is interfered with by any stop order, injunction or
other order or requirement of the SEC or any other governmental agency or
court, such Registration Statement will be deemed not to have become effective
during the period of such interference until the offering of Registrable
Securities pursuant to such Registration Statement may legally resume.

          (e) If the Company and the Subsidiary Guarantors fail to comply with
the provisions of this Section 2 or if the Exchange Offer Registration
Statement or the Shelf Registration Statement fails to become effective, then
additional interest (the "Additional Interest") shall become payable in
respect of the Securities as follows:

          (i) if (A) neither the Exchange Offer Registration Statement nor the
     Shelf Registration Statement is filed with the SEC on or prior to 45 days
     after the Closing Date or (B) notwithstanding that the Company and the
     Subsidiary Guarantors have consummated or will consummate an Exchange
     Offer, the Company and the Subsidiary Guarantors are required to file a
     Shelf Registration Statement and such Shelf Registration Statement is not
     filed on or prior to the date required hereby, then commencing on the day
     after either such required filing date, Additional Interest payable in
     respect of the Securities shall accrue on the principal amount of the
     Securities at a rate of 0.5% per annum for the first 90 days immediately
     following each such filing date, such Additional Interest rate increasing
     by an additional 0.5% per annum at the beginning of each subsequent
     90-day period; or


                                       5


<PAGE>


          (ii) if (A) neither the Exchange Offer Registration Statement nor a
     Shelf Registration Statement is declared effective by the SEC on or prior
     to 150 days after the Closing Date or (B) notwithstanding that the
     Company and the Subsidiary Guarantors have consummated or will consummate
     an Exchange Offer, the Company and the Subsidiary Guarantors are required
     to file a Shelf Registration Statement and such Shelf Registration
     Statement is not declared effective by the SEC on or prior to the 60th
     day following the date such Shelf Registration Statement was filed, then,
     commencing on the day after either such required effective date,
     Additional Interest payable in respect of the Securities shall accrue on
     the principal amount of the Securities at a rate of 0.5% per annum for
     the first 90 days immediately following such date, such Additional
     Interest rate increasing by an additional 0.5% per annum at the beginning
     of each subsequent 90-day period; or

          (iii) if (A) the Company and the Subsidiary Guarantors have not
     exchanged Exchange Securities for all Registrable Securities validly
     tendered in accordance with the terms of the Exchange Offer on or prior
     to the 30th day after the date on which the Exchange Offer Registration
     Statement was declared effective or (B) if applicable, the Shelf
     Registration Statement has been declared effective and such Shelf
     Registration Statement ceases to be effective at any time prior to the
     second anniversary of its effective date (other than after such time as
     all the Registrable Securities have been disposed of thereunder), then
     Additional Interest payable in respect of the Securities shall accrue on
     the principal amount of the Securities at a rate of 0.5% per annum for
     the first 90 days commencing on (x) the 31st day after such effective
     date, in the case of (A) above, or (y) the day such Shelf Registration
     Statement ceases to be effective, in the case of (B) above, such
     Additional Interest rate increasing by an additional 0.5% per annum at
     the beginning of each subsequent 90-day period; provided, however, that
     the Additional Interest rate on the notes may not exceed in the aggregate
     2.0% per annum; provided, further, however, that (a) upon the filing of
     the Exchange Offer Registration Statement or a Shelf Registration
     Statement (in the case of clause (i) above), (b) upon the effectiveness
     of the Exchange Offer Registration Statement or a Shelf Registration
     Statement (in the case of clause (ii) above), or (c) upon the exchange of
     Exchange Securities for all Registrable Securities tendered (in the case
     of clause (iii)(A) above), or upon the effectiveness of the Shelf
     Registration Statement which had ceased to remain effective (in the case
     of clause (iii)(B) above), Additional Interest on the Securities as a
     result of such clause (or the relevant subclause thereof), as the case
     may be, shall cease to accrue.

          (f) Without limiting the remedies available to the Initial Purchaser
and the Holders, the Company and the Subsidiary Guarantors acknowledge that
any failure by the Company and the Subsidiary Guarantors to comply with their
obligations under Section 2(a) and Section 2(b) hereof may result in material
irreparable injury to the Initial Purchaser or the Holders for which there is
no adequate remedy at law, that it will not be possible to measure damages for
such injuries precisely and that, in the event of any such failure, the
Initial Purchaser or any Holder may obtain such relief as may be required to
specifically enforce the Company's and the Subsidiary Guarantors' obligations
under Section 2(a) and Section 2(b) hereof.

     3.   Registration Procedures.

          In connection with the obligations of the Company and the Subsidiary
Guarantors with respect to the Registration Statements pursuant to Section
2(a) and Section 2(b) hereof, the Company and the Subsidiary Guarantors shall

     Act; to keep each Prospectus current during the period described under
     Section 4(3) and Rule 174 under the 1933 Act that is applicable to

     Registrable Securities, if any, without charge, as many copies of each
     Prospectus, including each preliminary Prospectus, and any amendment or
     supplement thereto and such other documents as such Holder or Underwriter
     may reasonably request, in order to facilitate the public sale or other
     disposition of the Registrable Securities; and the Company and each of
     the Subsidiary Guarantors consent to the use of such Prospectus and any
     amendment or supplement thereto in accordance with applicable law by each
     of the selling holders of Registrable Securities and any such
     Underwriters in connection with the offering and sale of the Registrable
     Securities covered by and in the manner described in such Prospectus or
     any amendment or supplement thereto in accordance with applicable law;

          (d) use its best efforts to register or qualify the Registrable
     Securities under all applicable state securities or "blue sky" laws of
     such jurisdictions within the United States as any Holder of Registrable
     Securities covered by a Registration Statement shall reasonably request
     in writing by the time the applicable Registration Statement is declared
     effective by the SEC, to cooperate with such Holders in connection with
     any filings required to be made with the National Association of
     Securities Dealers, Inc. and do any and all other acts and things which
     may be reasonably necessary or advisable to enable such Holder to
     consummate the disposition in each such jurisdiction of such Registrable
     Securities owned by such Holder; provided, however, that neither the
     Company nor any Subsidiary Guarantor shall be required to (i) qualify as
     a foreign corporation or as a dealer in securities in any jurisdiction
     where it would not otherwise be required to qualify but for this Section
     3(d), (ii) file any general consent to service of process or (iii)

     Initial Purchaser promptly and, if requested by any such Holder or
     counsel, confirm such advice in writing (i) when a Registration Statement
     has become effective and when any post-effective amendment thereto has
     been filed and becomes effective, (ii) of any request by the SEC or any
     state securities authority for amendments and supplements to a
     Registration Statement and Prospectus or for additional information after
     the Registration Statement has become effective, (iii) of the issuance by
     the SEC or any state securities authority of any stop order suspending
     the effectiveness of a Registration Statement or the initiation of any
     proceedings for that purpose, (iv) if, between the effective date of a
     Registration Statement and the closing of any sale of Registrable
     Securities covered thereby, the representations and warranties of the
     Company and each Subsidiary Guarantor contained in any underwriting
     agreement, securities sales agreement or other similar agreement, if any,
     relating to the offering cease to be true and correct in all material
     respects or if the


                                       7


<PAGE>



     Company or any Subsidiary Guarantor receives any notification with
     respect to the suspension of the qualification of the Registrable
     Securities for sale in any jurisdiction or the initiation of any
     proceeding for such purpose, (v) of the happening of any event during the
     period a Shelf Registration Statement is effective which makes any
     statement made in such Registration Statement or the related Prospectus
     untrue in any material respect or which requires the making of any
     changes in such Registration Statement or Prospectus in order to make the
     statements therein not misleading and (vi) of any determination by the
     Company or any Subsidiary Guarantor that a post-effective amendment to a
     Registration Statement would be appropriate;

          (f) make every reasonable effort to obtain the withdrawal of any
     order suspending the effectiveness of a Registration Statement at the
     earliest possible moment and provide immediate notice to each Holder of
     the withdrawal of any such order;

          (g) in the case of a Shelf Registration, furnish to each Holder of
     Registrable Securities, without charge, at least one conformed copy of
     each Registration Statement and any post-effective amendment thereto
     (without documents incorporated therein by reference or exhibits thereto,
     unless requested);

          (h) in the case of a Shelf Registration, cooperate with the selling
     Holders of Registrable Securities to facilitate the timely preparation
     and delivery of certificates representing Registrable Securities to be
     sold and not bearing any restrictive legends and enable such Registrable
     Securities to be in such denominations (consistent with the provisions of
     the Indenture) and registered in such names as the selling Holders may
     reasonably request at least two business days prior to the closing of any
     sale of Registrable Securities;

          (i) in the case of a Shelf Registration, upon the occurrence of any
     event contemplated by Section 3(e)(v) hereof, use its best efforts to
     prepare and file with the SEC a supplement or post-effective amendment to
     a Registration Statement or the related Prospectus or any document
     incorporated therein by reference or file any other required document so
     that, as thereafter delivered to the purchasers of the Registrable
     Securities, such Prospectus will not contain any untrue statement of a
     material fact or omit to state a material fact necessary to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading. The Company and each of the Subsidiary Guarantors
     agree to notify the Holders to suspend use of the Prospectus as promptly
     as practicable after the occurrence of such an event, and the Holders
     hereby agree to suspend use of the Prospectus until the Company has
     amended or supplemented the Prospectus to correct such misstatement or
     omission;

          (j) a reasonable time prior to the filing of any Registration
     Statement, any Prospectus, any amendment to a Registration Statement or
     amendment or supplement to a Prospectus or any document which is to be
     incorporated by reference into a Registration Statement or a Prospectus
     after initial filing of a Registration Statement, provide copies of such
     document to the Initial Purchaser and its counsel (and, in the case of a
     Shelf Registration Statement, the Holders and their counsel) and make
     such of the representatives of the Company and the Subsidiary Guarantors
     as shall be reasonably requested by the Initial Purchaser or its counsel
     (and, in the case of a Shelf Registration Statement, the Holders or their
     counsel) available for discussion of such document, and shall not at any
     time file or make any amendment to the Registration Statement, any
     Prospectus or any amendment of or supplement to a Registration Statement
     or a Prospectus or any document which is to be incorporated by reference
     into a Registration Statement or a Prospectus, of which the Initial
     Purchaser and its counsel (and, in


                                       8


<PAGE>


     the case of a Shelf Registration Statement, the Holders and their
     counsel) shall not have previously been advised and furnished a copy or
     to which the Initial Purchaser or its counsel (and, in the case of a
     Shelf Registration Statement, the Holders or their counsel) shall
     reasonably object;

          (k) in the case of a Shelf Registration, obtain a CUSIP number for
     all Registrable Securities not later than the effective date of the Shelf
     Registration Statement;

          (l) cause the Indenture to be qualified under the Trust Indenture
     Act of 1939, as amended (the "TIA"), in connection with the registration
     of the Exchange Securities or Registrable Securities, as the case may be,
     cooperate with the Trustee and the Holders to effect such changes to the
     Indenture as may be required for the Indenture to be so qualified in
     accordance with the terms of the TIA and execute, and use its best
     efforts to cause the Trustee to execute, all documents as may be required
     to effect such changes and all other forms and documents required to be
     filed with the SEC to enable the Indenture to be so qualified in a timely
     manner;

          (m) in the case of a Shelf Registration, make available for
     inspection by a representative of the Holders of the Registrable
     Securities, any Underwriter participating in any disposition pursuant to
     such Shelf Registration Statement, and attorneys and accountants
     designated by the Holders, at reasonable times and in a reasonable
     manner, all financial and other records, pertinent documents and
     properties of the Company and the Subsidiary Guarantors, and cause the
     respective officers, directors and employees of the Company and the
     Subsidiary Guarantors to supply all information reasonably requested by
     any such representative, Underwriter, attorney or accountant in
     connection with a Shelf Registration Statement;

          (n) in the case of a Shelf Registration, use their best efforts to
     cause all Registrable Securities to be listed on any securities exchange
     or any automated quotation system on which similar securities issued by
     the Company or any of the Subsidiary Guarantors are then listed if
     requested by the Majority Holders, to the extent such Registrable
     Securities satisfy applicable listing requirements; provided, however,
     that the Company's and the Guarantors' obligations pursuant to this
     Section 3(n) shall terminate upon (i) the approval for listing of the
     Notes by the Luxembourg Stock Exchange, the London Stock Exchange or any
     other securities exchange or automated quotation system designated by the
     Majority Holders or (ii) the rejection by any such exchange of the Notes
     for such listing, if it is established that such rejection is due to
     actions or omissions of the Initial Purchaser or any of the Holders;

          (o) use their best efforts to cause the Exchange Securities or
     Registrable Securities, as the case may be, to be rated by two nationally
     recognized statistical rating organizations (as such term is defined in
     Rule 436(g)(2) under the 1933 Act);

          (p) if reasonably requested by any Holder of Registrable Securities
     covered by a Registration Statement, (i) promptly incorporate in a
     Prospectus supplement or post-effective amendment such information with
     respect to such Holder as such Holder reasonably requests to be included
     therein and (ii) make all required filings of such Prospectus supplement
     or such post-effective amendment as soon as the Company has received
     notification of the matters to be incorporated in such filing; and

          (q) in the case of a Shelf Registration, enter into such customary
     agreements and take all such other actions in connection therewith
     (including those requested by the Holders of a majority of the
     Registrable Securities being sold) in order to expedite or facilitate the
     disposition of such Registrable Securities including, but not limited to,
     an Underwritten Offering and in such connection, (i) to the extent
     possible, make such representations and warranties to the Holders and any
     Underwriters of such Registrable Securities with respect to the business
     of the Company and the Subsidiary Guarantors and their respective
     subsidiaries, the Registration Statement, Prospectus and documents


                                       9


<PAGE>



     incorporated by reference or deemed incorporated by reference, if any, in
     each case, in form, substance and scope as are customarily made by
     issuers to underwriters in underwritten offerings and confirm the same if
     and when requested, (ii) obtain opinions of counsel to the Company and
     the Subsidiary Guarantors (which counsel and opinions, in form, scope and
     substance, shall be reasonably satisfactory to the Holders and such
     Underwriters and their respective counsel) addressed to each selling
     Holder and Underwriter of Registrable Securities, covering the matters
     customarily covered in opinions requested in underwritten offerings,
     (iii) obtain "cold comfort" letters from the independent certified public
     accountants of the Company and the Subsidiary Guarantors (and, if
     necessary, any other certified public accountant of any subsidiary of the
     Company, or of any business acquired by the Company or any of the
     Subsidiary Guarantors for which financial statements and financial data
     are required to be included in the Registration Statement) addressed to
     each selling Holder and Underwriter of Registrable Securities, such
     letters to be in customary form and covering matters of the type
     customarily covered in "cold comfort" letters in connection with
     underwritten offerings, and (iv) deliver such documents and certificates
     as may be reasonably requested by the Holders of a majority in principal
     amount of the Registrable Securities being sold or by the Underwriters,
     and which are customarily delivered in underwritten offerings, to
     evidence the continued validity of the representations and warranties of
     the Company and the Subsidiary Guarantors made pursuant to clause (i)
     above and to evidence compliance with any customary conditions contained
     in an underwriting agreement.

          In the case of a Shelf Registration Statement, the Company and the
Subsidiary Guarantors may require each Holder of Registrable Securities to
furnish to the Company and the Subsidiary Guarantors such information
regarding the Holder and the proposed distribution by such Holder of such
Registrable Securities as the Company and the Subsidiary Guarantors may from
time to time reasonably request in writing.

          In the case of a Shelf Registration Statement, each Holder agrees
that, upon receipt of any notice from the Company and the Subsidiary
Guarantors of the happening of any event of the kind described in Section
3(e)(v) hereof, such Holder will forthwith discontinue disposition of
Registrable Securities pursuant to a Registration Statement until such
Holder's receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 3(i) hereof, and, if so directed by the Company, such
Holder will deliver to the Company (at its expense) all copies in its
possession, other than permanent file copies then in such Holder's possession,
of the Prospectus covering such Registrable Securities current at the time of
receipt of such notice. If the Company shall give any such notice to suspend
the disposition of Registrable Securities pursuant to a Registration
Statement, the Company shall extend the period during which the Registration
Statement shall be maintained effective pursuant to this Agreement by the
number of days during the period from and including the date of the giving of
such notice to and including the date when the Holders shall have received
copies of the supplemented or amended Prospectus necessary to resume such
dispositions. The Company may give any such notice only twice during any 365
day period and any such suspensions may not exceed 30 days for each suspension
and there may not be more than two suspensions in effect during any 365 day
period.

          The Holders of Registrable Securities covered by a Shelf
Registration Statement who desire to do so may sell such Registrable
Securities in an Underwritten Offering. In any such Underwritten Offering, the
investment banker or investment bankers and manager or managers (the
"Underwriters") that will administer the offering will be selected by the
Majority Holders of the Registrable Securities included in such offering.

     4.   Participation of Broker-Dealers in Exchange
Offer.

          (a) The Staff of the SEC has taken the position that any
broker-dealer that receives Exchange Securities for its own account in the
Exchange Offer in exchange for Securities that were acquired by such
broker-dealer as a result of market-making or other trading activities (a


                                      10


<PAGE>


"Participating Broker-Dealer"), may be deemed to be an "underwriter" within
the meaning of the 1933 Act and must deliver a prospectus meeting the
requirements of the 1933 Act in connection with any resale of such Exchange
Securities.

          The Company and the Subsidiary Guarantors understand that it is the
Staff's position that if the Prospectus contained in the Exchange Offer
Registration Statement includes a plan of distribution containing a statement
to the above effect and the means by which Participating Broker-Dealers may
resell the Exchange Securities, without naming the Participating
Broker-Dealers or specifying the amount of Exchange Securities owned by them,
such Prospectus may be delivered by Participating Broker-Dealers to satisfy
their prospectus delivery obligation under the 1933 Act in connection with
resales of Exchange Securities for their own accounts, so long as the
Prospectus otherwise meets the requirements of the 1933 Act.

          (b) In light of the above, notwithstanding the other provisions of
this Agreement, the Company and the Subsidiary Guarantors agree that the
provisions of this Agreement as they relate to a Shelf Registration shall also
apply to an Exchange Offer Registration to the extent, and with such
reasonable modifications thereto as may be, reasonably requested by the
Initial Purchaser or by one or more Participating Broker-Dealers, in each case
as provided in clause (ii) below, in order to expedite or facilitate the
disposition of any Exchange Securities by Participating Broker-Dealers
consistent with the positions of the Staff recited in Section 4(a) above;
provided that:

          (i) the Company and the Subsidiary Guarantors shall not be required
     to amend or supplement the Prospectus contained in the Exchange Offer
     Registration Statement, as would otherwise be contemplated by Section
     3(i), for a period exceeding 180 days after the last Exchange Date (as
     such period may be extended pursuant to the penultimate paragraph of
     Section 3 of this Agreement) and Participating Broker-Dealers shall not
     be authorized by the Company or the Subsidiary Guarantors to deliver and
     shall not deliver such Prospectus after such period in connection with
     the resales contemplated by this Section 4; and

          (ii) the application of the Shelf Registration procedures set forth
     in Section 3 of this Agreement to an Exchange Offer Registration, to the
     extent not required by the positions of the Staff of the SEC or the 1933
     Act and the rules and regulations thereunder, will be in conformity with
     the reasonable request to the Company and the Subsidiary Guarantors by
     the Initial Purchaser or with the reasonable request in writing to the
     Company and the Subsidiary Guarantors by one or more broker-dealers who
     certify to the Initial Purchaser, the Company and the Subsidiary
     Guarantors in writing that they anticipate that they will be
     Participating Broker-Dealers; and provided further that, in connection
     with such application of the Shelf Registration procedures set forth in
     Section 3 to an Exchange Offer Registration, the Company and the
     Subsidiary Guarantors shall be obligated (x) to deal only with one entity
     representing the Participating Broker-Dealers, which shall be the Initial
     Purchaser unless it elects not to act as such representative, (y) to pay
     the fees and expenses of only one counsel representing the Participating
     Broker-Dealers, which shall be counsel to the Initial Purchaser unless
     such counsel elects not to so act and (z) to cause to be delivered only
     one, if any, "cold comfort" letter with respect to the Prospectus in the
     form existing on the last Exchange Date and with respect to each
     subsequent amendment or supplement, if any, effected during the period
     specified in clause (i) above.

          (c) The Initial Purchaser shall have no liability to the Company,
any Subsidiary Guarantor or any Holder with respect to any request that they
may make pursuant to Section 4(b) above.

          5. Indemnification and Contribution.

          (a) The Company and each of the Subsidiary Guarantors, jointly and
severally, agree to indemnify and hold harmless the Initial Purchaser, each
Holder and each person, if any, who controls the Initial Purchaser or any
Holder within the meaning of either Section 15 of the 1933 Act or Section 20
of the 1934 Act, or is under common control with, or is controlled by, the
Initial Purchaser or any Holder, from and against all losses, claims, damages
and liabilities (including, without limitation, any legal or other expenses
reasonably incurred by the Initial Purchaser, any Holder or any such
controlling or affiliated person in connection with defending or investigating
any such action or claim) caused by any untrue statement or alleged untrue
statement of a material fact contained in any Registration Statement (or any
amendment thereto) pursuant to which Exchange Securities or Registrable
Securities were registered under the 1933 Act, including all documents
incorporated therein by reference, or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, or caused by any
untrue statement or alleged untrue statement of a material fact contained in
any Prospectus (as amended or supplemented if the Company and the Subsidiary
Guarantors shall have furnished any amendments or supplements thereto), or
caused by any omission or alleged omission to state therein a material fact
necessary to make the statements therein in light of the circumstances under
which they were made not misleading, except insofar as such losses, claims,
damages or liabilities are caused by any such untrue statement or omission or
alleged untrue statement or omission based upon information relating to the
Initial Purchaser or any Holder furnished to the Company and the Subsidiary
Guarantors in writing by the Initial Purchaser or any selling Holder expressly
for use therein; provided, however, that the foregoing indemnity agreement
with respect to any preliminary prospectus contained in any such Registration
Statement shall not inure to the benefit of any Holder from whom the person
asserting any such losses, claims, damages or liabilities purchased
Securities, or any person controlling such Holder if a copy of the Prospectus
(as then aended or supplemented if any Guarantor or the Company shall have
furnished any amendments or supplements thereto) was not sent or given by or
on behalf of such Holder to such person, at or prior to the written
confirmation of the sale of the Securities to such person, and if the
Prospectus (as so amended or supplemented) would have cured the defect giving
rise to such losses, claims, damages or liabilities, unless such failure was
the result of noncompliance by any Guarantor or the Company with Section 3(j)
hereof. In connection with any Underwritten Offering permitted by Section 3,
each of the Company and each of the Subsidiary Guarantors will also indemnify
the Underwriters, if any, selling brokers, dealers and similar securities
industry professionals participating in the distribution, their officers and
directors and each Person who controls such Persons (within the meaning of the
Securities Act and the Exchange Act) to the same extent as provided above with
respect to the indemnification of the Holders, if requested in connection with
any Registration Statement.

          (b) Each Holder agrees, severally and not jointly, to indemnify and
hold harmless the Company, the Subsidiary Guarantors, the Initial Purchaser
and the other selling Holders, and each of their respective directors,
officers who sign the Registration Statement and each Person, if any, who
controls the Company, the Subsidiary Guarantors, the Initial Purchaser and any
other selling Holder within the meaning of either Section 15 of the 1933 Act
or Section 20 of the 1934 Act to the same extent as the foregoing indemnity
from the Company and each Subsidiary Guarantor to the Initial Purchaser and
the Holders, but only with reference to information relating to such Holder
furnished to the Company and the Subsidiary Guarantors in writing by such
Holder expressly for use in any Registration Statement (or any amendment
thereto) or any Prospectus (or any amendment or supplement thereto).

          (c) In case any proceeding (including any governmental
investigation) shall be instituted involving any person in respect of which
indemnity may be sought pursuant to either paragraph (a) or paragraph (b)
above, such person (the "indemnified party") shall promptly notify the person
against whom such indemnity may be sought (the "indemnifying party") in
writing and the indemnifying party, upon request of the indemnified party,
shall retain counsel reasonably


                                      12

satisfactory to the indemnified party to represent the indemnified party and
any others the indemnifying party may designate in such proceeding and shall
pay the fees and disbursements of such counsel related to such proceeding. In
any such proceeding, any indemnified party shall have the right to retain its
own counsel, but the fees and expenses of such counsel shall be at the expense
of such indemnified party unless (i) the indemnifying party and the
indemnified party shall have mutually agreed to the retention of such counsel
or (ii) the named parties to any such proceeding (including any impleaded
parties) include both the indemnifying party and the indemnified party and
representation of both parties by the same counsel would be inappropriate due
to actual or potential differing interests between them. It is understood that
the indemnifying party shall not, in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for (a) the fees and expenses
of more than one separate firm (in addition to any local counsel) for the
Initial Purchaser and all persons, if any, who control the Initial Purchaser
within the meaning of either Section 15 of the 1933 Act or Section 20 of the
1934 Act, and (b) the fees and expenses of more than one separate firm (in
addition to any local counsel) for the Company and the Subsidiary Guarantors,
their directors, their officers who sign the Registration Statement and each
person, if any, who controls the Company or any of the Subsidiary Guarantors
within the meaning of either such Section and (c) the fees and expenses of
more than one separate firm (in addition to any local counsel) for all Holders
and all persons, if any, who control any Holders within the meaning of either
such Section, and that all such fees and expenses shall be reimbursed as they
are incurred. In such case involving the Initial Purchaser and persons who
control the Initial Purchaser, such firm shall be designated in writing by the
Initial Purchaser. In such case involving the Holders and such persons who
control Holders, such firm shall be designated in writing by the Majority
Holders. In all other cases, such firm shall be designated by the Company and
the Subsidiary Guarantors. The indemnifying party shall not be liable for any
settlement of any proceeding effected without its written consent but, if
settled with such consent or if there be a final judgment for the plaintiff,
the indemnifying party agrees to indemnify the indemnified party from and
against any loss or liability by reason of such settlement or judgment.
Notwithstanding the foregoing sentence, if at any time an indemnified party
shall have requested an indemnifying party to reimburse the indemnified party
for fees and expenses of counsel as contemplated by the second and third
sentences of this paragraph, the indemnifying party agrees that it shall be
liable for any settlement of any proceeding effected without its written
consent if (i) such settlement is entered into more than 30 days after receipt
by such indemnifying party of the aforesaid request and (ii) such indemnifying
party shall not have reimbursed the indemnified party for such fees and
expenses of counsel in accordance with such request prior to the date of such
settlement. No indemnifying party shall, without the prior written consent of
the indemnified party, effect any settlement of any pending or threatened
proceeding in respect of which such indemnified party is or could have been a
party and indemnity could have been sought hereunder by such indemnified
party, unless such settlement includes an unconditional release of such
indemnified party from all liability on claims that are the subject matter of
such proceeding.

          (d) If the indemnification provided for in paragraph (a) or
paragraph (b) of this Section 4 is unavailable to an indemnified party or
insufficient in respect of any losses, claims, damages or liabilities, then
each indemnifying party under such paragraph, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable
by such indemnified party as a result of such losses, claims, damages or
liabilities in such proportion as is appropriate to reflect the relative fault
of the indemnifying party or parties on the one hand and of the indemnified
party or parties on the other hand in connection with the statements or
omissions that resulted in such losses, claims, damages or liabilities, as
well as any other relevant equitable considerations. The relative fault of the
Company, the Subsidiary Guarantors and the Holders shall be determined by
reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Company or the Subsidiary
Guarantors or by the Holders and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission. The Holders' respective obligations to contribute pursuant to this
Section 5(d) are several in proportion to the respective number of Registrable
Securities of such Holder that were registered pursuant to a Registration
Statement.


                                      13


<PAGE>



          (e) The Company, each Subsidiary Guarantor and each Holder agree
that it would not be just or equitable if contribution pursuant to this
Section 5 were determined by pro rata allocation or by any other method of
allocation that does not take account of the equitable considerations referred
to in paragraph (d) above. The amount paid or payable by an indemnified party
as a result of the losses, claims, damages and liabilities referred to in
paragraph (d) above shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such
action or claim. Notwithstanding the provisions of this Section 5, no Holder
shall be required to indemnify or contribute any amount in excess of the
amount by which the total price at which Registrable Securities were sold by
such Holder exceeds the amount of any damages that such Holder has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the 1933 Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The remedies provided for in this Section 5 are not
exclusive and shall not limit any rights or remedies which may otherwise be
available to any indemnified party at law or in equity.

          The indemnity and contribution provisions contained in this Section
5 shall remain operative and in full force and effect regardless of (i) any
termination of this Agreement, (ii) any investigation made by or on behalf of
the Initial Purchaser, any Holder or any person controlling the Initial
Purchaser or any Holder, or by or on behalf of the Company or any Subsidiary
Guarantor, its officers or directors or any person controlling the Company or
any Subsidiary Guarantor, (iii) acceptance of any of the Exchange Securities
and (iv) any sale of Registrable Securities pursuant to a Shelf Registration
Statement.

     6.   Miscellaneous.

          (a) No Inconsistent Agreements. Neither the Company nor any
Subsidiary Guarantor has entered into, and on or after the date of this
Agreement will not enter into, any agreement which is inconsistent with the
rights granted to the Holders of Registrable Securities in this Agreement or
otherwise conflicts with the provisions hereof. The rights granted to the
Holders hereunder do not in any way conflict with and are not inconsistent
with the rights granted to the holders of the Company's or the Subsidiary
Guarantors' other issued and outstanding securities under any such agreements.

          (b) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company and the Subsidiary Guarantors have
obtained the written consent of Holders of at least a majority in aggregate
principal amount of the outstanding Registrable Securities affected by such
amendment, modification, supplement, waiver or consent; provided, however,
that no amendment, modification, supplement, waiver or consents to any
departure from the provisions of Section 5 hereof shall be effective as
against any Holder of Registrable Securities unless consented to in writing by
such Holder.

          (c) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, telex, telecopier, or any courier guaranteeing overnight
delivery (i) if to a Holder, at the most current address given by such Holder
to the Company by means of a notice given in accordance with the provisions of
this Section 6(c), which address initially is, with respect to the Initial
Purchaser, the address set forth in the Purchase Agreement; and (ii) if to the
Company and the Subsidiary Guarantors, initially at the Company's and
Subsidiary Guarantors' addresses set forth in the Purchase Agreement and
thereafter at such other addresses, notice of which is given in accordance
with the provisions of this Section 6(c).


                                      14


<PAGE>



          All such notices and communications shall be deemed to have been
duly given: at the time delivered by hand, if personally delivered; five
business days after being deposited in the mail, postage prepaid, if mailed;
when answered back, if telexed; when receipt is acknowledged, if telecopied;
and on the next business day if timely delivered to an air courier
guaranteeing overnight delivery.

          Copies of all such notices, demands, or other communications shall
be concurrently delivered by the person giving the same to the Trustee, at the
address specified in the Indenture.

          (d) Successors and Assigns. This Agreement shall inure to the
benefit of and be binding upon the successors, assigns and transferees of each
of the parties, including, without limitation and without the need for an
express assignment, subsequent Holders; provided that nothing herein shall be
deemed to permit any assignment, transfer or other disposition of Registrable
Securities in violation of the terms of the Purchase Agreement. If any
transferee of any Holder shall acquire Registrable Securities, in any manner,
whether by operation of law or otherwise, such Registrable Securities shall be
held subject to all of the terms of this Agreement, and by taking and holding
such Registrable Securities such person shall be conclusively deemed to have
agreed to be bound by and to perform all of the terms and provisions of this
Agreement and such person shall be entitled to receive the benefits hereof.
The Initial Purchaser (in its capacity as Initial Purchaser) shall have no
liability or obligation to the Company or any Subsidiary Guarantor with
respect to any failure by a Holder to comply with, or any breach by any Holder
of, any of the obligations of such Holder under this Agreement.

          (e) Purchases and Sales of Notes. The Company and each Subsidiary
Guarantor shall not, and shall use their best efforts to cause their
affiliates (as defined in Rule 405 under the 1933 Act) not to, purchase and
then resell or otherwise transfer any Securities.

          (f) Third Party Beneficiary. The Holders shall be third party
beneficiaries to the agreements made hereunder among the Company, the
Subsidiary Guarantors, and the Initial Purchaser, and shall have the right to
enforce such agreements directly to the extent it deems such enforcement
necessary or advisable to protect its rights or the rights of Holders
hereunder.

          (g) Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

          (h) Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

          (i) Governing Law. This Agreement shall be governed by and construed
in accordance with the internal laws of the State of New York.

          (j) Severability. In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstance,
is held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provision in every other respect and of the
remaining provisions contained herein shall not be affected or impaired
thereby.

       RE:  Amtran, Inc. Registration Statement on Form S-4
            -----------------------------------------------

Dear Sirs:

          I am the General Counsel of Amtran, Inc., an Indiana corporation
(the "Company"), and am rendering this opinion in connection with the
Registration Statement on Form S-4 (the "Registration Statement") of the
Company, with respect to $75,000,000 aggregate principal amount of 10- 1/2%
Senior Exchange Notes due 2004 (the "Exchange Notes") of the Company. The
Exchange Notes are being issued in exchange for $75,000,000 aggregate
principal amount of the Company's 10-1/2% Senior Notes due 2004 (the
"Outstanding Notes"), pursuant to an exchange offer (the "Exchange Offer").
The Outstanding Notes were originally issued in a transaction exempt from the
registration requirements of the Securities Act of 1933, as amended (the
"Securities Act").

          I have examined (i) the Indenture, dated July 24, 1997, as
supplemented by the First Supplemental Indenture, dated December 21, 1999
(the "Indenture") among the Company, as issuer, American Trans Air, Inc.,
Ambassadair Travel Club, Inc., ATA Leisure Corp. (formerly ATA Vacations,
Inc.), Amber Travel, Inc., American Trans Air Training Corporation,
American Trans Air ExecuJet, Inc., Amber Air Freight Corporation and
Chicago Express Airlines, Inc. as guarantors (the "Guarantors"), and First
Security Bank, N.A., as trustee (the "Trustee"), pursuant to which the
Exchange Notes will be issued; and (ii) such other documents and made such
other investigations as I have deemed necessary or advisable for purposes
of this opinion. Based thereon, I am of the opinion that:

     1.   The Company is a corporation duly organized and validly existing
          under the laws of the State of Indiana.

     2.   Each of the Guarantors is a corporation duly organized and
          validly existing under the laws of the State of Indiana, except
          for Chicago Express Airlines, Inc., which is duly organized and
          validly existing under the laws of the state of Illinois.

     3.   The Indenture has been duly authorized, executed and delivered by
          each of the Company, the Guarantors and the Trustee.

     4.   The Guarantees (as defined in the Indenture) have been duly
          authorized and issued by the Guarantors.

     5.   At the time the Exchange Offer is consummated, the Exchange Notes
          will have been duly authorized, executed, authenticated by each of
          the Company, the Guarantors and the Trustee, and delivered in
          exchange for the Outstanding Notes pursuant to the Exchange Offer.

          I am admitted to practice in the State of Indiana, and I express no
opinion as to matters governed by any laws other than the laws of the State of
Indiana and the Federal laws of the United States of America.

          I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement. I also consent to the use of my name under the caption

                    10-1/2% SENIOR EXCHANGE NOTES DUE 2004

Ladies and Gentlemen:

          We have acted as counsel for Amtran, Inc., an Indiana corporation
(the "Company"), in connection with the registration under the Securities
Act of, of 1933, as amended (the "Securities Act"), of $75,000,000
aggregate principal amount of the Company's 10-1/2% Senior Exchange Notes
due 2004 (the "Exchange Notes"), to be issued under an Indenture dated as
July 24, 1997 as supplemented by the First Supplemental Indenture, dated
December 21, 1999 (the "Indenture"), among the Company, as issuer, American
Trans Air, Inc., Ambassadair Travel Club, Inc., ATA Leisure Corp. (formerly
ATA Vacations, Inc.), Amber Travel, Inc., American Trans Air Training
Corporation, American Trans Air Execujet, Inc., Amber Air Freight
Corporation, and Chicago Express Airlines, Inc., as guarantors (the
"Guarantors"), and First Security Bank, N.A., as trustee (the "Trustee"),
in exchange for $75,000,000 aggregate principal amount of 10-1/2% Senior
Notes due 2004 (the "Outstanding Notes"), pursuant to an exchange offer
(the "Exchange Offer"). The Outstanding Notes were originally issued in a
transaction exempt from the registration requirements of the Securities
Act.

          In that connection, we have examined originals, or copies certified
or otherwise identified to our satisfaction, of such documents, corporate
records and other instruments as we have deemed necessary or appropriate for
the purposes of this opinion, including the Indenture.

          Based on the foregoing, we are of opinion as follows:

          1. Assuming that the Indenture has been duly authorized, executed
and delivered by each of the Company, the Guarantors and the Trustee, the
Indenture constitutes a


<PAGE>


                                                                             2

legal, valid and binding obligation of the Company and the Guarantors,
enforceable against the Company and the Guarantors in accordance with its
terms (subject to applicable bankruptcy, insolvency, reorganization,
moratorium, fraudulent transfer or other similar laws affecting creditors'
rights generally from time to time in effect and to general principles of
equity, including, without limitation, concepts of materiality,
reasonableness, good faith and fair dealing, regardless of whether such
enforceability is considered in a proceeding in equity or at law).

          2. Assuming that the Exchange Notes have been duly authorized by the
Company, the Notes, when executed and authenticated in accordance with the
provisions of the Indenture and delivered in exchange for the Outstanding
Notes pursuant to the Exchange Offer, will constitute legal, valid and binding
obligations of the Company, enforceable against the Company in accordance with
their terms and entitled to the benefits of the Indenture (subject to
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
transfer or other laws affecting creditors' rights generally from time to time
in effect and to general principles of equity, including, without limitation,
concepts of materiality, reasonableness, good faith and fair dealing,
regardless of whether such enforceability is considered in a proceeding in
equity or at law); in expressing the opinion set forth in this paragraph 2, we
have assumed, that the form of the Notes will conform to those included in the
Indenture.

          3. Assuming that the Guarantees (as defined in the Indenture) have
been duly authorized by the Guarantors, and assuming the due execution and
delivery of the Indenture in accordance with its terms by the Guarantors and
the Company, the Guarantees will be legal, valid and binding obligations of
each of the Guarantors, enforceable against the Guarantors in accordance with
their terms and entitled to the benefits of the Indenture (subject to
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
transfer or other laws affecting creditors' rights generally from time to time
in effect and to general principles of equity, including, without limitation,
concepts of materiality, reasonableness, good faith and fair dealing,
regardless of whether such enforceability is considered in a proceeding in
equity or at law).

          We are admitted to practice in the State of New York, and we express
no opinion as to matters governed by any laws other than the laws of the State
of New York and the Federal laws of the United States of America. In
particular, we do not purport to pass on any matter governed by the laws of
the State of Indiana.

          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
the continuance of an Event of Default, shall bear interest at the following
rates per annum:

                              (i) During such periods that any Advance is a
               Prime Rate Advance, the Prime Rate plus the Margin.

                              (ii) During such periods that any Advance is a
               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.

          2.05 Periodic Mandatory Reductions of Borrowing Base.


<PAGE>


          The Borrowing Base shall automatically be reduced as follows:

               (a) In the event of any Disposition of any Aviation Property,
the Borrowing Base shall be reduced by an amount equal to one hundred percent
(100%) of the appraised value, as of the most recent Adjustment Date, of such
disposed Aviation Property, and the Borrower shall prepay the Revolving Credit
Loans, or cash collateralize the Letter of Credit Advances if all of the
Revolving Credit Loans are or will be paid in full, by an amount equal to the
proceeds of such Disposition.

               (b) Upon any loss or damage to any Aviation Property which
cannot or is not repaired in accordance with the terms of Section 2.09(e), the
Borrowing Base shall be reduced by an amount equal to such loss or damage, but
not in excess of the amount required under Section 2.05(a) upon Disposition of
such Aviation Property, and the Borrower shall prepay the Revolving Credit
Loans, or cash collateralize the Letter of Credit Advances if all of the
Revolving Credit Loans are or will be paid in full, by an amount equal to the
greater of the insurance proceeds of such loss or damage or the value of such
Aviation Property.

          2.06 Fees.

               (a) Borrower shall pay to the Agent and First Chicago Capital
Markets, Inc. (the "Arranger") for the benefit of the Agent and the Arranger
fees in amounts and at such times and for such periods as agreed to between
the Agent, the Arranger and Borrower.

               (b) The Borrower shall pay to the Agent for the benefit of each
Bank, a non-use fee equal to the Margin of the difference between each Bank's
daily average Commitment during each fiscal quarter of the Borrower and such
Bank's share of the daily average outstanding Advances during such fiscal
quarter of the Borrower. Such fee shall be in addition to all other charges
and shall be paid on the fifteenth (15th) Banking Day following the end of
each fiscal quarter of Borrower. For purposes of calculating the non-use fee,
outstanding Letters of Credit shall not be deemed to be included in any Bank's
share of outstanding Advances.

               (c) On or before the date of issuance of any Letter of Credit,
Borrower agrees (i) to pay to the Agent for the benefit of the Banks a fee
computed at the Margin of the maximum amount available to be drawn from time
to time under such Letter of Credit for the period from and including the date
of issuance of such Letter of Credit to and including the stated expiry date
of such Letter of Credit and (ii) to pay the Agent for its own account a fee
computed at the rate of one-eighth percent (1/8%) per annum of the maximum
amount available to be drawn from time to time under such Letter of Credit for
the period from and including the date of issuance of such Letter of Credit to
and including the stated expiry date of such Letter of Credit; provided,
however, that with respect to any Letter of Credit the face value of which
exceeds $250,000, such fee shall be payable initially, on or before the date
of issuance of such Letter of Credit for the period commencing with such date
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.


<PAGE>


          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.

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.

                                  ARTICLE X.
                                 MISCELLANEOUS

          10.01 Notices. Any communications between the parties hereto or
notices or requests provided herein to be given may be given by mailing the
same, first class postage prepaid, or by telex or electronic transmission to
each party at its address set forth on the signature pages thereto (with a
copy to each address indicated for notices), or to such other address as any
party may in writing hereafter indicate to Borrower and the Banks. Notices
shall be effective on the date sent by electronic transmission and telex and
three (3) Banking Days after the date sent by U.S. mail.

          10.02 Successors and Assigns. This Agreement shall bind and inure to
the benefit of the parties hereto and their respective permitted successors
and assigns; provided, however, that Borrower shall not assign this Agreement
or any of its rights hereunder without the prior written consent of the Banks.


<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.

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

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
sale, lease, transfer or other disposition of the assets of the Borrower or
any consolidation or merger of the Borrower with or into any other person,
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

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.

performance of this Mortgage, all at such reasonable times and as often as may
reasonably be requested. Mortgagee shall have no duty to make any such
inspection or examination and Mortgagee shall not incur any liability or
obligation by reason of not making any such inspection or examination.

     SECTION 3. Liens, Encumbrances and Claims. The Mortgagor will not

defined in the Credit Agreement.

     SECTION 4. Maintenance and Operation. Mortgagor shall bear all risk of
loss of or damage to the Mortgaged Aviation Property. The Mortgagor, at its
own cost and expense, shall service, repair and maintain each Mortgaged
Airplane and each Mortgaged Engine and shall install replacement equipment and
parts on each Mortgaged Airplane and each Mortgaged Engine so as to keep each
Mortgaged Airplane and each Mortgaged Engine in such operating condition as
may be required to permit each such Mortgaged Airplane and Mortgaged Engine to
be utilized in commercial charter operations and scheduled airline service
world-wide and shall maintain all records, logs and other materials that may
be required to permit each Mortgaged Airplane and each Mortgaged Engine to be
so utilized. Mortgagor will comply and will cause compliance with all laws,
regulations or orders of governmental authority having jurisdiction over
Mortgagor or the Mortgaged Aviation Property, including all applicable
operational and maintenance requirements of the Federal Aviation
Administration, and will at all times maintain in effect appropriate United
States FAA Certificates of Airworthiness for each of the Mortgaged Airplanes.
The Mortgagor agrees that the Mortgaged Airplanes and Mortgaged Engines will
not be maintained, used or operated in violation of any law or any rule,
regulation or order of any government or governmental authority having
jurisdiction (domestic or foreign), or in violation of any airworthiness
certificate, license or registration relating to the Mortgaged Airplanes or
Mortgaged Engines issued by any such authority, and in the event that such
laws, rules, regulations or orders require alteration of any Mortgaged
Airplane or any Mortgaged Engine, the Mortgagor, at its own cost and expense,
will conform thereto or obtain conformance therewith and will maintain the
same in proper operating condition under such laws, rules, regulations and
orders; provided, however, that the Mortgagor may, in good faith, contest the
validity or application of any such law, rule, regulation or order in any
reasonable manner that does not materially adversely affect the interests of
Mortgagee under this Mortgage. Without the prior written consent of Mortgagee,
Mortgagor shall not fly any Mortgaged Airplane or any Mortgaged Engine or
suffer any thereof to be flown or located to, from or within (a) any area
excluded from coverage by any insurance policy required hereunder to be
maintained in effect with respect to each of the Mortgaged Airplanes or any
Mortgaged Engine or (b) any area of hostilities recognized or designated by
the United States Government or an insurance carrier then insuring aircraft in
Borrower's fleet, unless fully covered by war-risk hull insurance or unless
such Mortgaged Airplane or such Mortgaged Engine is operated or used under
contract or lease with the Government of the United States of America under
which contract that Government shall assume all liability for any damage,
loss, destruction or failure to return possession of such Mortgaged Airplane
or such Mortgaged Engine at the end of the term of such contract.

     SECTION 5. Sale, Assignment, Lease, etc. Except as otherwise provided in
the Credit Agreement, the Mortgagor will not, without the prior written
consent of Mortgagee, sell, assign, lease or otherwise dispose of or
relinquish possession of any of the Mortgaged Aviation Property, except that,
unless a Default Event (as hereinafter defined) shall have occurred and be
continuing, the Mortgagor may, in the ordinary course of business: (i)
transfer possession of any Mortgaged Airplane or any Mortgaged Engine to the
United States Government pursuant to a contract or lease meeting the
requirements of the clause (b) of the proviso to the second sentence of
Section 4, a copy of which shall be furnished to the Mortgagee; (ii) transfer
possession of any Mortgaged Airplane or any Mortgaged Engine to the
manufacturer thereof or any other organization for testing, repairs,
servicing, maintenance, overhaul, alterations or modifications; (iii) enter
into any lease of any Mortgaged Engine provided that any such lease does not
have a term in excess of ninety (90) days; and (iv) enter into any "wet lease"
or other similar arrangement under which the Mortgagor maintains operational
control of the Mortgaged Aviation Property and which do not have a term in
excess of six (6) months; provided, however, that, in connection with any of
the foregoing, neither any

                                       4


<PAGE>


Mortgaged Airplane nor any Mortgaged Engine shall be or become subject to any
pooling, interchange or exchange agreement or arrangement without the prior
written approval of the Mortgagee.

     SECTION 6. Release of Mortgaged Aviation Property. The property subject
to this Mortgage shall be automatically released from the lien and security
interest of this Mortgage and the Mortgagee shall release such property upon
irrevocable payment and performance in full of the Obligation and the
expiration or termination of the Commitments (as defined in the Credit
Agreement). Portions of the property subject to this Mortgage shall also be
released under the terms and conditions specified in Section 3.02 of the
Credit Agreement.

     SECTION 7. Subsequently Mortgaged Engines. If an Event of Loss shall
occur with respect to a Mortgaged Engine, but not to a Mortgaged Airplane, the
Mortgagor shall give Mortgagee prompt written notice thereof and shall, within
30 days after the occurrence of such Event of Loss, duly convey to Mortgagee,
for the benefit of itself, the Administrative Agent and the Banks, a lien and
security interest in another equivalent engine of the same model and
manufacturer owned or acquired by the Mortgagor (and not already subject to a
security interest securing the Obligation), free and clear of all security
interests, liens, charges and other encumbrances (except Permitted
Encumbrances) and having a value and utility reasonably equivalent to, and
being in as good operating condition as, and having performance and durability
characteristics reasonably equivalent to, the Mortgaged Engine with respect to
which such Event of Loss occurred if such Mortgaged Engine were in the
condition and repair as required by the terms hereof immediately prior to the
occurrence of such Event of Loss (any such engine so substituted hereunder
being herein called a "Replacement Engine").

     In connection with any substitutions hereunder, the Mortgagor shall
deliver to Mortgagee the following:

          (A) a Supplemental Chattel Mortgage substantially in the form of
Annex 1 hereto duly executed by the Mortgagor appropriately describing the
Replacement Engine or Engines to be subjected to the lien and security
interest of this Mortgage;

          (B) a certificated signed by the President and by the Treasurer of
the Mortgagor (an "Officers' Certificate"), dated the date of execution of
such Supplemental Chattel Mortgage, stating:

          (1)  that the Mortgagor is the owner of the Replacement Engines
               described in such Supplemental Chattel Mortgage, free and clear
               of all security interests, liens, charges and other
               encumbrances except Permitted Encumbrances and that legal and
               beneficial title thereto is vested in the Mortgagor;

          (2)  that such Supplemental Chattel Mortgage has been duly
               authorized, executed and delivered by the Mortgagor;

          (C) an opinion or opinions of counsel for the Mortgagor acceptable
to Mortgagee, as to matters set forth in subparagraph (2)(x) below, and of
Crowe & Dunlevy, P.C., or other counsel acceptable to Mortgagee, as to the
other matters set forth below, each such opinion to be dated the date of
execution of such Supplemental Chattel Mortgage, stating, as the case may be:

          (D) that the Replacement Engine or Engines described in such
Supplemental Chattel


                                       5


<PAGE>


Mortgage are free and clear of all recorded security interests, liens, charges
and other encumbrances, except Permitted Encumbrances;

          (i) that such Supplemental Chattel Mortgage (x) has been duly
authorized, executed and delivered by the Mortgagor and is enforceable against
the Mortgagor and (y) creates a valid first security interest in and to the
Replacement Engine or Engines described in such Supplemental Chattel Mortgage,
subject to Permitted Encumbrances, enforceable, wherever such Replacement
Engine or Engines are located within the United States, against all third
parties and securing all obligations purported to be secured thereby, and such
security interest is fully perfected; and

          (1) that such Supplemental Chattel Mortgage has been duly filed for
recordation in accordance with the provisions of the Act; it being understood
that in rendering the foregoing opinions, counsel for matters set forth in
subparagraph (2)(x) above may state that they do not give any opinion as to
the laws of any jurisdictions other than the United States of America and the
State of Indiana and that their opinions are subject to applicable bankruptcy,
insolvency and similar laws affecting creditors' rights generally and to
general principles of equity (regardless of whether enforcement is sought in a
proceeding in equity or at law), and Crowe & Dunlevy, P.C., or such other
counsel for other matters may state that their opinions are subject to the
limitations, assumptions and exceptions set forth in the opinion of Crowe &
Dunlevy, P.C., delivered in connection with the filing of this Mortgage; and

          (2) such evidence of title of the Mortgagor to such Replacement
Engine or Engines, of the value thereof and compliance with the insurance
provisions of Section 9 with respect thereto, as Mortgagee may reasonably
request.

          SECTION 8. Replacement of Parts; Alterations, Modification and
Additions. (a) The Mortgagor, at its own cost and expense, will promptly
replace all appliances, parts, instruments, appurtenances, accessories and
other equipment of whatever nature (collectively, the "Parts"), which may from
time to time be incorporated or installed in or attached to any Mortgaged
Airplane or any Mortgaged Engine and which may from time to time become worn
out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or
permanently rendered unfit for use for any reason whatever. In addition, in
the ordinary course of maintenance, service, repair or testing, the Mortgagor
may remove any Parts, whether or not worn out, lost, stolen, destroyed,
seized, confiscated, damaged beyond repair or permanently rendered unfit for
use; provided, however, that, except as otherwise provided in paragraph (b)
below, the Mortgagor shall replace such Parts as promptly as practicable. All
replacement Parts shall be free and clear of all security interests, liens,
charges and other encumbrances (except Permitted Encumbrances) and shall be in
as good operating condition as, and shall have a value and utility reasonably
equivalent to, the value and utility of Parts replaced.

          Except as provided in paragraph (b) below, all Parts owned by the
Mortgagor at any time removed from any Mortgaged Airplane or any Mortgaged
Engine shall remain subject to the lien and security interest of this
Mortgage, no matter where located, until such time as such Parts shall be
replaced by Parts which have been incorporated or installed in or attached to
such Mortgaged Airplane or such Mortgaged Engine and which meet the
requirements for replacement Parts specified above. Immediately upon any
replacement Part owned by the Mortgagor becoming incorporated or installed in
or attached to such Mortgaged Airplane or any Mortgaged Engine as above
provided, without further act, such replacement Part shall become subject to
the lien and security interest of this Mortgage.

                                       6


<PAGE>


          (b) The Mortgagor, at its own cost and expense, may from time to
time make such alterations and modifications in and additions to any Mortgaged
Airplane or any Mortgaged Engine as the Mortgagor may deem desirable in the
proper conduct of its business; provided, however, that no such alteration,
modification or addition shall diminish the value, utility, condition or
airworthiness of any Mortgaged Airplane or any Mortgaged Engine below the
value, utility, condition or airworthiness thereof immediately prior to such
alteration, modification or addition. All Parts owned by the Mortgagor
incorporated or installed in or attached to or added to any Mortgaged Airplane
or any Mortgaged Engine as the result of such alteration, modification or
addition shall, without further act, become subject to the lien and security
interest of this Mortgage.

          SECTION 9. Insurance, Events of Loss, Etc. (a) The Mortgagor will at
all times carry and maintain in effect, or cause to be carried and maintained
in effect, on the Mortgaged Aviation Property, at its own cost and expense,
(i) third party and passenger liability insurance in an amount not less than
the greater of (x) $150,000,000.00 per occurrence and (y) the amount of such
insurance applicable to any other aircraft of the same model and manufacturer
as the aircraft described on Schedule I hereto which is operated by the
Mortgagor either as owner or as original primary lessee (and not as sublessee
or assignee of another primary lessee) on which the Mortgagor carries
insurance; (ii) property damage liability insurance; (iii) aircraft all-risk
hull insurance for each Mortgaged Airplane and the Mortgaged Engines and Parts
belonging to, installed in or appurtenant to each Mortgaged Airplane (which
all-risk hull insurance shall include coverage of Mortgaged Engines and Parts
while temporarily removed from the Mortgaged Airplanes and not replaced by
similar components) in an amount not less than 100% of the replacement cost
thereof (or such other amount as the Mortgagee may approve); (iv) all-risk of
physical loss or damage insurance on Mortgaged Engines and Parts while removed
from the Mortgaged Airplane; (v) war-risk insurance (when available from the
United States or an agency thereof or a commercial carrier and required by
Section 4); and (vi) baggage and cargo liability insurance; in each case in
such amounts (except where amounts are specified above) and in such form,
including without limitation the form of the loss payable clause and the
designation of named insureds, and with such insurance companies, underwriters
or funds of recognized responsibility as shall be reasonably satisfactory to
Mortgagee and as shall be declared from time to time by independent aircraft
insurance brokers (who may be the brokers regularly employed by the
Mortgagor), appointed by the Mortgagor and reasonably acceptable to Mortgagee,
to be necessary or advisable (in view of the insurance usually carried by
corporations engaged in the same or a similar business as the Mortgagor,
similarly situated with the Mortgagor and owning similar aircraft and engines)
for the protection of the interests of Mortgagee. All insurance required
hereunder shall provide for payment in the United States in U.S. Dollars. All
third party and passenger liability and property damage liability insurance
shall insure against liability which Mortgagee or the Mortgagor might incur by
reason of the ownership or operation of any of the Mortgaged Airplanes in or
over any area (including the high seas) in which any of the Mortgaged
Airplanes is operated or located, shall be of the type usually carried by
corporations engaged in the same or a similar business, similarly situated
with the Mortgagor, and owning similar aircraft and engines and shall cover
risks of the kind customarily insured against by such corporations and, in the
case of property damage liability insurance, shall be in amounts that are not
less than property damage liability insurance applicable to the other aircraft
in the Mortgagor's fleet on which the Mortgagor carries such insurance.

          (b) All liability policies shall name Mortgagee as an additional
insured as its interests may appear. All other policies required hereby
covering loss or damage to the Mortgaged Aviation Property shall name
Mortgagee as an additional insured as its interests may appear and as a lender
loss payee and shall provide that any payment thereunder for any loss or
damage shall be paid to Mortgagee, except as permitted under the Credit
Agreement; provided, however, if no Default Event has occurred and is

                                       7


<PAGE>


continuing and the Mortgagor is otherwise entitled to receive a payment
thereunder, proceeds under such policies which are received by the Mortgagee
may be disbursed by the Mortgagee to the Mortgagor upon the written request of
the Mortgagor subject to and provided that each of the following conditions is
satisfied in form and substance satisfactory to the Mortgagee: (i) all such
proceeds shall be applied to repair in full any such loss or damage, (ii) the
Mortgagee shall have determined in its sole discretion that such repairs are
feasible and economically prudent, (iii) there are sufficient proceeds on
deposit with the Mortgagee to completely repair any such loss or damage, or
the Mortgagor shall deposit funds with the Mortgagee in the amount of any
deficiency, (iv) all disbursements of such proceeds shall be paid by the
Mortgagee from time to time as works progresses based upon disbursement
procedures acceptable to the Mortgagee, (v) the repairs can be completed
within sixty (60) days from the date of such loss or damage or such other time
agreed to in writing between Mortgagor and Mortgagee, (vi) the Mortgagor shall
pay or reimburse the Mortgagee for all of its reasonable costs and expenses
incurred in connection with the disbursement of such proceeds, and (vii) upon
completion of the repairs, the Mortgagee's collateral would not be impaired or
value reduced in any way from the value thereof prior to the loss or damage,
as determined by the Mortgagee. All policies shall insure the interests of
Mortgagee regardless of any breach or violation by the Mortgagor of
warranties, declarations or conditions contained in such policies or any
action or inaction of the Mortgagee or others; each such policy shall be
primary without right of contribution from any other insurance which is
carried by the Mortgagor and shall expressly provide that all provisions
thereof, except the limits of liability, shall operate in the same manner as
if there were a separate policy covering each insured; each such policy shall
waive any right of subrogation of the insurers against Mortgagee; each such
policy shall waive any right of the insurers to any set-off or counterclaim or
any other deduction, whether by attachment or otherwise, in respect of any
liability of Mortgagee; and each such policy shall provide that, if any
premium or installment is not paid when due, or if such insurance is canceled
or terminated for any reason whatsoever, or if the scope of coverage or the
limits of liability are reduced or any other material adverse change is made
in or to the rights of Mortgagee, the insurers will promptly notify Mortgagee
in writing and any such cancellation, termination or change shall not be
effective as to the Mortgagee for 30 days (seven days in the case of war-risk
policies) after receipt of such notice, and that appropriate certification
shall be made to Mortgagee by each insurer with respect thereto.

          (c) Any insurance proceeds received as the result of any property
damage loss not constituting an Event of Loss with respect to any Mortgaged
Airplane or any Mortgaged Engine shall be applied in payment for any repair or
replacement required by the terms of Section 7 or 8 if not already paid for by
the Mortgagor, and any balance remaining after any such repair or replacement
(or if already paid for by Mortgagor, all such insurance proceeds), shall be
retained by, or immediately paid over to, the Mortgagor; provided, however,
that no Default Event shall have occurred and be continuing; and provided
further, however, that Mortgagee shall have received from the Mortgagor prior
to the making of any such payment the Mortgagor a certificate signed by the
President of the Mortgagor certifying that the property so damaged has been
repaired in full, that the costs of such repair (which costs shall be
specified in such certificate) have been paid in full, and that no Default
Event shall have occurred and be continuing. If such repairs are made pursuant
to contracts requiring advance or progress payments, such insurance requiring
advance or progress payments, such insurance proceeds shall be paid over to
the Mortgagor from time to time upon appropriate certification by the
Mortgagor.

          (d) On or before the date of this Mortgage and thereafter at least
once during each calendar year commencing with 1998, the Mortgagor will cause
its insurance broker(s) to furnish the Mortgagee a detailed report signed by
such broker(s) showing the insurance then carried and maintained on the
Mortgaged Airplanes and Mortgaged Engines and stating the opinion of such
broker(s) that the

                                       8


<PAGE>


insurance then carried and maintained on the Mortgaged Airplanes and Mortgaged
Engines complies with the terms thereof. The Mortgagor will cause such
broker(s) to agree to advise the Mortgagee in writing promptly of any default
in the payment of any premium and of any other act or omission on the part of
the Mortgagor of which it shall have knowledge that might invalidate or render
unenforceable, in whole or in part, any such insurance. The Mortgagor will
promptly deliver to the Mortgagee, if requested by the Mortgagee, copies of
certificates of insurance evidencing all such insurance.

          (e) For purposes of this Mortgage the term "Event of Loss" shall
mean any of the following events with respect to any Mortgaged Airplane or any
Mortgaged Engine: (i) the actual total loss of such Mortgaged Airplane or such
Mortgaged Engine, (ii) the Mortgaged Airplane or such Mortgaged Engine shall
become lost, stolen (and not returned within 30 days), destroyed, damaged
beyond repair or permanently rendered unfit for use for any reason whatsoever,
(iii) any damage to such Mortgaged Airplane or such Mortgaged Engine that
shall result in an insurance settlement with respect thereto on the basis of a
total loss, or (iv) the condemnation, confiscation or seizure of, or
requisition of title to or use (other than use by the United States
Government) of, such Mortgaged Airplane or such Mortgaged Engine continuing to
the earlier of the expiration of 60 days thereafter or the receipt of
insurance or other proceeds with respect thereto.

          SECTION 10. Indemnification and Expenses. The Mortgagor does hereby
assume liability for, and does hereby agree to indemnify, protect, save and
keep harmless the Mortgagee, the Administrative Agent and the Banks and their
successors, assigns, representatives, officers, directors, agents and servants
(the "Indemnitees") from and against any and all liabilities, obligations,
losses, damages, penalties, claims, actions, suits, costs, expenses and
disbursements, including legal expenses, of whatsoever kind and nature imposed
on, incurred by or asserted against any of the Indemnitees (whether or not
also indemnified against by any other person) in any way relating to or
arising out of this Mortgage, the Credit Agreement, the Note or the ownership,
lease, service, control, repair, overhaul, testing, inspection, possession,
management, use, operation, condition, sale or other disposition of any
Mortgaged Aviation Property; provided, however, that the Mortgagor shall not
be required to indemnify anyone for the willful misconduct or gross negligence
of any of the Indemnitees. The indemnities contained in this Section shall
continue in full force and effect notwithstanding the termination of this
Mortgage with respect to claims arising or liabilities incurred prior to such
termination.

          SECTION 11. Default Events; Remedies. (a) The following events shall
constitute "Default Events" (whether any such event shall be voluntary or
involuntary or come about or be effected by operation of law or pursuant to or
in compliance with any judgment, decree or order of any court or any order,
rule or regulation of any administrative or governmental body) and each such
Default Event shall be deemed to exist and continue so long as, but only as
long as, it shall not have been remedied:

               (i) the occurrence of any "Event of Default", as that term is
defined in the Credit Agreement; or

               (ii) the Mortgagor shall fail to carry and maintain insurance
on or with respect to the Mortgaged Airplanes and/or Mortgaged Engines in
accordance with the provisions of Section 9; or

               (iii) the Mortgagor shall voluntarily create, incur or assume
any lien, security interest, charge or encumbrance on or with respect to any
part of or all the Mortgaged Aviation Property in violation of Section 3; or

                                       9


<PAGE>


               (iv) the Mortgagor shall fail to maintain the registration of
any of the Mortgaged Airplanes under the Act (and the regulations thereunder);
or

               (v) the Mortgagor shall sell, assign, lease or otherwise
dispose of or relinquish possession of any of the Mortgaged Aviation Property
in violation of Section 5; or

               (vi) the Mortgagor shall fail to perform or observe any other
covenant or agreement to be performed or observed by it hereunder and such
failure shall continue unremedied for a period of thirty (30) days after
written notice thereof by Mortgagee; or

               (vii) any material representation or warranty made by the
Mortgagor herein or any document or certificate furnished by the Mortgagor to
Mortgagee in connection herewith shall at any time prove to have been
incorrect in any material respect when made; or

               (viii) this Mortgage shall at any time for any reason cease to
be in full force and effect or shall be declared to be null and void other
than solely by reason of the gross negligence or willful misconduct of the
Mortgagee.

          (b) If any Default Event shall occur and be continuing, then, in any
such event, Mortgagee may forthwith to the extent permitted by applicable law:
(i) apply to a court of competent jurisdiction to obtain specific performance
or observance by the Mortgagor of any covenant, agreement or undertaking on
the part of the Mortgagor hereunder that the Mortgagor shall have failed to
observe or perform or to obtain aid in the execution of any power granted
herein, and/or (ii) proceed to foreclose upon and against the lien and
security interest created by this Mortgage according to the laws of the
applicable jurisdiction by doing any one or more or all of the acts described
in paragraph (c) below and/or the following acts, as the Mortgagee in its sole
and complete discretion may then elect:

               (A) exercise all the rights and remedies upon default, in
foreclosure and otherwise, available to a mortgagee or secured party under the
provisions of applicable law;

               (B) institute legal proceedings to foreclose upon and against
the lien and security interest granted by this Mortgage, to recover judgments
for the Obligation then due and owing and secured hereby, and to collect the
same out of any of or all the Mortgaged Aviation Property or the proceeds of
any sale thereof;

               (C) institute legal proceedings for the sale, under the
judgment or decree of any court of competent jurisdiction, of any of or all
the Mortgaged Aviation Property;

               (D) without regard to the adequacy of the security for the
Obligation by virtue of this Mortgage or any other collateral or to the
solvency of the Mortgagor, institute legal proceedings for the appointment of
a receiver or receivers with respect to any of or all the Mortgaged Aviation
Property pending foreclosure hereunder or for the sale of any of or all the
Mortgaged Aviation Property under the order of a court of competent
jurisdiction or under other legal process; or

               (E) personally or by agents or attorneys, enter upon any
premises where the Mortgaged Aviation Property or any part thereof may then be
located, and take possession of all or any part

                                      10


<PAGE>


thereof, and hold, store and keep idle, or lease, operate or otherwise use or
permit the use of, the Mortgaged Aviation Property or any part thereof, for
such time and upon such terms as the Mortgagee may in its sole and complete
discretion deem to be in its best interest, and demand, collect, and retain
all rent, earnings, and other sums due and to become due in respect of the
same from any party whomsoever, accounting only for net earnings, if any,
arising from such use and charging against all receipts from the use of the
same or from the sale thereof, by court proceedings or pursuant to paragraph
(c) below, all other costs, expenses, charges, damages and other losses
resulting from such use.

          At any sale pursuant to this Section 11, whether under the power of
sale or by virtue of judicial proceedings, it shall not be necessary for
Mortgagee or a public officer under order of a court to have present physical
or constructive possession of the Mortgaged Aviation Property to be sold. Upon
any sale hereunder of any of or all the Mortgaged Aviation Property or any
interest therein, the receipt of the officer making such sale under judicial
proceedings or of Mortgagee shall be sufficient discharge to the purchaser for
the purchase money, and such purchaser shall not be obligated to see to the
application thereof. Any sale hereunder of any of or all the Mortgaged
Aviation Property or any interest therein shall, to the extent permitted by
applicable law, be a perpetual bar against the Mortgagor with respect to such
Mortgaged Aviation Property or interest therein, as the case may be.

          (c) If Mortgagee should elect to foreclose upon and against the lien
and security interest created in and by this Mortgage, the Mortgagor shall,
upon demand of Mortgagee, deliver to Mortgagee all or any part of the
Mortgaged Aviation Property at such time or times and place or places as
Mortgagee may specify; and Mortgagee is hereby authorized and empowered to the
extent permitted by law, with or without the aid of process of law, to enter
upon any premises where the Mortgaged Aviation Property or any part thereof
may be located and take possession of and remove the same. Mortgagee may
thereafter sell, lease and dispose of, or cause to be sold, leased or disposed
of, all or any part of the Mortgaged Aviation Property at one or more public
or private sales, leasings or other dispositions, at such places and times and
on such terms and conditions as the Mortgagee may deem fit. Mortgagee agrees
to give the Mortgagor at least ten days' written notice of the date fixed for
any public sale, or the date on or after which will occur the execution of any
contract for any private sale, or any of the Mortgaged Aviation Property.

          SECTION 12. Application of Proceeds. If a Default Event shall occur
and be continuing, the proceeds of any sale, lease or other disposition of all
or any part of the Mortgaged Aviation Property under this Mortgage and all
other sums realized by Mortgagee pursuant to this Mortgage or any proceedings
hereunder shall be applied in the following order of priority:

          First: To the payment of the costs and expenses of such sale, lease,
disposition or the realization, including reasonable compensation to the
Mortgagee's agents and counsel, and all expenses, liabilities and advances
made or incurred by Mortgagee in connection therewith, including without
limitation, taxes upon or with respect to the sale, lease, disposition or
realization and the payment of taxes and liens, if any, prior to the lien and
security interest of this Mortgage (except any taxes or liens to which the
respective sale, lease, disposition or realization shall have been subject)
and to the payment of expenses and the reimbursements of payments incurred or
made by Mortgagee pursuant to Section 15;

          Second: To the payment of the remainder of the Obligation.

          Third: Upon payment in full of the Obligation, the balance, if any,
to the


                                      11


<PAGE>


Mortgagor or to such other person(s) as may lawfully be entitled to the
remainder or as any court of competent jurisdiction may direct.

          SECTION 13. Mortgagee as Attorney. The Mortgagor hereby irrevocably
and severally appoints Mortgagee the true and lawful attorney of the Mortgagor
(with full power of substitution) in the name, place and stead of, and at the
expense of, the Mortgagor in connection with the enforcement of the rights and
remedies provided for in Sections 11 and 12: (a) to give any necessary
receipts or acquittances for amounts collected or received thereunder, (b) to
make all necessary transfer of all or any part of the Mortgaged Aviation
Property in connection with any sale, lease or other disposition made pursuant
hereto and (c) to execute and deliver for value all necessary or appropriate
bills of sale, assignments and other instruments in connection with any such
sale, lease or other disposition, the Mortgagor hereby ratifying and
confirming all that its said attorney (or any substitute) shall lawfully do
hereunder and pursuant hereto. Nevertheless, if so requested by Mortgagee or a
purchaser or lessor, the Mortgagor shall ratify and confirm any such sale,
lease or other disposition by executing and delivering to Mortgagee or such
purchaser or lessor all proper bills of sale, assignments, releases, leases
and other instruments as may be designated in any such request.

          SECTION 14. Remedies Cumulative; Fees and Expenses. (a) No failure
or delay on the part of Mortgagee in exercising, and no course of dealing with
respect to, any right, power or remedy under this Mortgage, and no notice or
demand that may be given to or made upon the Mortgagor with respect to any
such right, power or remedy, shall constitute a waiver thereof or limit or
impair the rights of Mortgagee to take any other or similar action or to
exercise any other right, power or remedy granted in this Mortgage or
otherwise available to Mortgagee; nor shall any single or partial exercise of
any right, power or remedy under this Mortgage include any other or further
exercise thereof or the exercise of any other right, power or remedy granted
in this Mortgage or otherwise available to Mortgagee or prejudice its rights
against the Mortgagor in any respect. Each and every remedy of the Mortgagee
shall be cumulative and shall not be exclusive or any other remedies provided
now or hereafter at law, in equity or otherwise.

               (b) The Mortgagor shall reimburse Mortgagee for all counsel
fees and other expenses paid or incurred by Mortgagee in exercising any
rights, powers or remedies granted hereby.

               (c) Mortgagor agrees, to the extent now or hereafter permitted
by applicable law, that neither it nor anyone claiming through or under it
will set up, claim or seek to take advantage of any valuation, appraisement,
stay, extension or redemption law now or hereafter in force in any locality
where any property subject to the lien and security interest of this Mortgage
may be located, in order to prevent, hinder or delay the enforcement or
foreclosure of this Mortgage, or the sale of the Mortgaged Aviation Property
(or any part thereof), or the purchaser's rights to absolute possession
thereof immediately after such sale. Mortgagor, for itself and all who may at
any time claim through or under it, hereby waives, to the full extent now or
hereafter permitted by applicable law, the benefit of all such laws, and any
and all right to have any of the Mortgaged Aviation Property marshalled upon
any such sale.

          SECTION 15. Mortgagee's Right to Perform for the Mortgagor. If the
Mortgagor shall fail to make any payment required to be made by it hereunder
or shall fail to perform or comply with any of its agreements contained
herein, Mortgagee may (but shall not be obligated to), upon ten (10) days'
prior written notice to the Mortgagor, make such payment or perform or comply
with such agreement (including, without limitation, the agreement of the
Mortgagor to maintain insurance pursuant to Section 9), and the amount of such
payment and the amount of the reasonable expenses of Mortgagee incurred in
connection

                                      12


<PAGE>


with such payment or the performance of or compliance with such agreement, as
the case may be, together with interest thereon at the highest post-maturity
per annum rate of interest provided for in the Note, shall be payable by the
Mortgagor to Mortgagee on demand and shall constitute additional indebtedness
secured by the lien and security interest of this Mortgage.

          SECTION 16. Further Assurances. The Mortgagor shall, at its own cost
and expense (except as otherwise stated below): (i) as soon as practicable
after the date hereof, cause each of the Mortgaged Airplanes and (if not
prevented by applicable law or regulations or governmental authority, and if
it will not adversely affect the proper use thereof) each Mortgaged Engine
included in the Mortgaged Aviation Property to be legibly marked (in a
reasonably prominent location) with such a plate, disk or other marking of
customary size, and bearing such a legend, as shall in the opinion of
Mortgagee be appropriate or desirable to evidence the fact that it is subject
to the lien and security interest created by this Mortgage (and until such
Mortgaged Airplane or such Mortgaged Engine shall be released from the lien
and security interest of this Mortgage, the Mortgagor shall not remove or
deface, or permit to be removed or defaced, any such plate, disk or other
marking or the identifying manufacturer's serial number, and, in the event of
such removal or defacement, shall promptly cause such plate, disk or other
marking or serial number to be promptly replaced) and (ii) cause this
Mortgage, and any and all additional instruments which shall be executed
pursuant to the terms hereof, to be kept, filed and recorded, at all times, in
such places in the United States and such places outside the United States to
which any of the Mortgaged Airplanes shall be operated as shall be required in
order to perfect and preserve the rights of Mortgagee hereunder and furnish to
Mortgagee an opinion or opinions of counsel or other evidence satisfactory to
Mortgagee of each such filing or recordation, and, without limitation of any
of the foregoing, at the request of Mortgagee, promptly correct any defect,
error or omission that may at any time hereafter be discovered in the contents
of this Mortgage or in the execution, acknowledgment or delivery hereof, and
will execute, acknowledge and deliver to Mortgagee such further documents and
assurances and take such further action as Mortgagee may from time to time
reasonably request in order to more effectively carry out the intent and
purpose of this Mortgage and to establish and protect the rights and remedies
created or intended to be created in favor of the Mortgagee hereunder without
limiting anything set forth above, the Mortgagor shall promptly file and
record such financing statements, continuation statements and other
instruments or documents with respect to the lien and security interest
created hereby as Mortgagee may reasonably deem necessary or appropriate fully
to perfect the lien and security interest, or fully to protect its interests,
hereunder. Where allowed by applicable law, Mortgagor hereby authorizes
Mortgagee to file financing statements and continuation statements signed only
by the Mortgagee.

          SECTION 17. Termination. Unless otherwise provided herein, this
Mortgage and the lien and security interest granted by this Mortgage shall
terminate at the date when the Obligation shall have been irrevocably fully
paid and performed and the Commitments (as defined in the Credit Agreement)
shall have expired or been terminated. Upon termination of this Mortgage, as
aforesaid, the Mortgagee shall execute and deliver to the Mortgagor at the
Mortgagor's expenses, such instruments of release and termination as shall be
appropriate in the premises.

          SECTION 18. Miscellaneous. Any provision of this Mortgage which
shall be prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate
or render unenforceable such provision in any other jurisdiction. To the
extent permitted by applicable law, the Mortgagor hereby waives any provision
of law that renders any provision hereof prohibited or unenforceable in any
respect. No term

                                      13

or provision of this Mortgage may be changed, waived, discharged or terminated
orally, but only by an instrument in writing signed by the Mortgagor and
Mortgagee. All the terms, provisions, conditions and covenants herein
contained shall be binding upon and shall inure to the benefit of the
Mortgagor, the Mortgagee and their respective successors and assigns. The
captions in this Mortgage are for convenience of reference only and shall not
define or limit any of the terms or provisions hereof.

          SECTION 19. Governing Law. This Mortgage shall be construed and
enforced in accordance with, and governed by the laws of the State of Indiana,
except to the extent that the law of some other jurisdiction may be
mandatorily applicable to the proceedings taken for the enforcement of the
rights of Mortgagee hereunder; provided, however, that any remedies herein
provided that are valid under the laws of the jurisdiction where proceedings
for the enforcement hereof shall be taken shall not be affected by any
invalidity thereof under the laws of the State of Indiana.

          SECTION 20. Execution and Delivery. This Mortgage may be executed in
any number of counterparts, and each such counterpart shall for all purposes
be deemed to be an original, and all such counterparts shall together
constitute one and the same instrument.

          IN WITNESS WHEREOF, the parties hereto have caused this Amended and
Restated Security Agreement And Chattel Mortgage to be duly executed, as of
the day and year first above written.

   Delivery of this instrument to an address other than as set forth above, or
transmission of instruction via facsimile other than as set forth above, will
not constitute a valid delivery.

   The undersigned acknowledges that he or she has received and reviewed the
Prospectus, dated , 2000 (the "Prospectus"), of Amtran, Inc., an Indiana
corporation (the "Company"), and this Letter of Transmittal (the "Letter"),
which together constitute the Company's offer (the "Exchange Offer") to
exchange an aggregate principal amount of up to $75,000,000 of its 10 1/2%
Senior Exchange Notes due 2004 (the "Exchange Notes"), for a like principal
amount of its issued and outstanding 10 1/2% Senior Notes due 2004 (the
"Outstanding Notes") with the holders thereof.

   For each Outstanding Note accepted for exchange, the holder of such
Outstanding Note will receive an Exchange Note having a principal amount equal
to that of the surrendered Outstanding Note. The Exchange Notes will bear
interest from the most recent interest payment date or if no interest has been
paid, from December 21, 1999, payable semiannually on February 1 and August 1
of each year commencing on August 1, 2000, at the rate of 10 1/2% per annum.
Holders of Outstanding Notes whose Outstanding Notes are accepted for exchange
will be deemed to have waived the right to receive any payment in respect of
interest on the Outstanding Notes accrued from July 24, 1997 until the date of
the issuance of the Exchange Notes. Consequently, holders who tender their
Outstanding Notes for Exchange Notes will receive the same interest payment on
August 1, 2000 (the first interest payment date with respect to the
Outstanding Notes and the Exchange Notes) that they would have received had
they not accepted the Exchange Offer.

   This Letter is to be completed by a holder of Outstanding Notes either if
certificates are to be forwarded herewith or if a tender of certificates for
Outstanding Notes, if available, is to be made by book-entry transfer to the
account maintained by the Exchange Agent at The Depository Trust Company (the
"Book-Entry Transfer Facility") pursuant to the procedures set forth in "The
Exchange Offer--Book-Entry Transfer" section of the Prospectus and an Agent's
Message is not delivered. Tenders by book-entry transfer may also be made by
delivering an Agent's Message in lieu of this Letter. The term "Agent's
Message" means a message, transmitted by the Book-Entry Transfer Facility to
and received by the Exchange Agent and forming a part of a Book-Entry
Confirmation (as defined below), which states that the Book-Entry Transfer
Facility has received an express acknowledgment from the tendering
participant, which acknowledgment states that such participant has received
and agrees to be bound by, and makes the representations and warranties
contained in, this Letter and that the Company may enforce this Letter against
such participant. Holders of Outstanding Notes whose certificates are not
immediately available, or who are unable to deliver their certificates or
confirmation of the book-entry tender of their Outstanding Notes into the
Exchange Agent's account at the Book-Entry Transfer Facility (the "Book-Entry
Confirmation") and all other documents required by this Letter to the Exchange
Agent on or prior to the Expiration Date, must tender their Outstanding Notes
according to the guaranteed delivery procedures set forth in "The Exchange
Offer--Guaranteed Delivery Procedures" section of the Prospectus. See
Instruction 1. Delivery of documents to the Book-Entry Transfer Facility does
not constitute delivery to the Exchange Agent.

              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

     Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to the Company the aggregate principal amount of
Outstanding Notes indicated above. Subject to, and effective upon, the
acceptance for exchange of the Outstanding Notes tendered hereby, the
undersigned hereby sells, assigns and transfers to, or upon the order of, the
Company all rights, title and interest in and to such Outstanding Notes as are
being tendered hereby.

     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Outstanding
Notes tendered hereby and that the Company will acquire good and unencumbered
title thereto, free and clear of all liens, restrictions, charges and
encumbrances and not subject to any adverse claim when the same are accepted
by the Company. The undersigned hereby further represents that any Exchange
Notes acquired in exchange for Outstanding Notes tendered hereby will have
been acquired in the ordinary course of business of the person receiving such
Exchange Notes, whether or not such person is the undersigned, that neither
the holder of such Outstanding Notes nor any such other person has an
arrangement or understanding with any person to participate in the
distribution of such Exchange Notes and that neither the holder of such
Outstanding Notes nor any such other person is an "affiliate," as defined in
Rule 405 under the Securities Act of 1933, as amended (the "Securities Act"),
of the Company.

     The undersigned also acknowledges that this Exchange Offer is being made
in reliance on an interpretation by the staff of the Securities and Exchange
Commission (the "Commission") that the Exchange Notes issued in exchange for
the Outstanding Notes pursuant to the Exchange Offer may be offered for
resale, resold and otherwise transferred by holders thereof (other than any
such holder that is an "affiliate" of the Company within the meaning of Rule
405 under the Securities Act), without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that such
Exchange Notes are acquired in the ordinary course of such holders' business
and such holders have no arrangements with any person to participate in the
distribution of such Exchange Notes. If the undersigned is not a
broker-dealer, the undersigned represents that it is not engaged in, and does
not intend to engage in, a distribution of Exchange Notes. If the undersigned
is a broker-dealer that will receive Exchange Notes for its own account in
exchange for Outstanding Notes, it represents that the Outstanding Notes to be
exchanged for the Exchange Notes were acquired by it as a result of
market-making activities or other trading activities and acknowledges that it
will deliver a prospectus in connection with any resale of such Exchange
Notes; however, by so acknowledging and by delivering a prospectus, the
undersigned will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.

     The undersigned will, upon request, execute and deliver any additional
documents deemed by the Company to be necessary or desirable to complete the
sale, assignment and transfer of the Outstanding Notes tendered hereby. All
authority conferred or agreed to be conferred in this Letter and every
obligation of the undersigned hereunder shall be binding upon the successors,
assigns, heirs, executors, administrators, trustees in bankruptcy and legal
representatives of the undersigned and shall not be affected by, and shall
survive, the death or incapacity of the undersigned. This tender may be
withdrawn only in accordance with the procedures set forth in "The Exchange
Offer--Withdrawal Rights" section of the Prospectus.

     Unless otherwise indicated herein in the box entitled "Special Issuance
Instructions" below, please deliver the Exchange Notes (and, if applicable,
substitute certificates representing Outstanding Notes for any Outstanding
Notes not exchanged) in the name of the undersigned or, in the case of a
book-entry delivery of Outstanding Notes, please credit the account indicated
above maintained at the Book-Entry Transfer Facility. Similarly, unless
otherwise indicated under the box entitled "Special Delivery Instructions"
below, please send the Exchange Notes (and, if applicable, substitute
certificates representing Outstanding Notes for any Outstanding Notes not
exchanged) to the undersigned at the address shown above in the box entitled
"Description of Outstanding Notes."

     THE UNDERSIGNED, BY COMPLETING THE BOX ENTITLED "DESCRIPTION OF
OUTSTANDING NOTES" ABOVE AND SIGNING THIS LETTER, WILL BE DEEMED TO HAVE
TENDERED THE OUTSTANDING NOTES AS SET FORTH IN SUCH BOX ABOVE.

                                 INSTRUCTIONS

                for the 10 1/2% Senior Exchange Notes due 2004
       in exchange for the 10 1/2% Senior Notes due 2004 of Amtran, Inc.

1.   Delivery of this Letter and Notes; Guaranteed Delivery Procedures.

     This letter is to be completed by noteholders either if certificates are
to be forwarded herewith or if tenders are to be made pursuant to the
procedures for delivery by book-entry transfer set forth in "The Exchange
Offer--Book-Entry Transfer" section of the Prospectus and an Agent's Message
is not delivered. Tenders by book-entry transfer may also be made by
delivering an Agent's Message in lieu of this Letter of Transmittal. The term
"Agent's Message" means a message, transmitted by the Book-Entry Transfer
Facility to and received by the Exchange Agent and forming a part of a
Book-Entry Confirmation, which states that the Book-Entry Transfer Facility
has received an express acknowledgment from the tendering participant, which
acknowledgment states that such participant has received and agrees to be
bound by, and makes the representations and warranties contained in, the
Letter of Transmittal and that the Company may enforce the Letter of
Transmittal against such participant. Certificates for all physically tendered
Outstanding Notes, or Book-Entry Confirmation, as the case may be, as well as
a properly completed and duly executed Letter (or manually signed facsimile
hereof or an Agent's Message in lieu thereof) and any other documents required
by this Letter, must be received by the Exchange Agent at the address set
forth herein or prior to the Expiration Date, or the tendering holder must
comply with the guaranteed delivery procedures set forth below. Outstanding
Notes tendered hereby must be in denominations of principal amount of $1,000
and any integral multiple thereof.

     Noteholders whose certificates for Outstanding Notes are not immediately
available or who cannot deliver their certificates and all other required
documents to the Exchange Agent on or prior to the Expiration Date, or who
cannot complete the procedure for book-entry transfer on a timely basis, may
tender their Outstanding Notes pursuant to the guaranteed delivery procedures
set forth in "The Exchange Offer--Guaranteed Delivery Procedures" section of
the Prospectus. Pursuant to such procedures, (i) such tender must be made
through an Eligible institution, (ii) prior to Midnight, New York City time,
on the Expiration Date, the Exchange Agent must receive from such Eligible
Institution a properly completed and duly executed Notice of Guaranteed
Delivery, substantially in the form provided by the Company (by facsimile
transmission, mail or hand delivery), setting forth the name and address of
the holder of Outstanding Notes, the certificate number of numbers of such
Outstanding Notes and the principal amount of Outstanding Notes tendered,
stating that the tender is being made thereby and guaranteeing that within
three New York Stock Exchange ("NYSE") trading days after the date of
execution of the Notice of Guaranteed Delivery, the certificates for all
physically tendered Outstanding Notes, in proper form for transfer, or a
Book-Entry Confirmation, as the case may be, together with a properly
completed and duly executed Letter (or a facsimile thereof or an Agent's
Message in lieu thereof), with any required signature guarantees and any other
documents required by the Letter will be deposited by the Eligible Institution
with the Exchange Agent, and (iii) the certificates for all physically
tendered Outstanding Notes, in proper form for transfer, or Book-Entry
Confirmation, as the case may be, together with a properly completed and duly
executed Letter (or a facsimile thereof or an Agent's Message in lieu thereof)
with any required signature guarantees and all other documents required by
this Letter, are received by the Exchange Agent within three NYSE trading days
after the date of execution of the Notice of Guaranteed Delivery.

     The method of delivery of this Letter, the Outstanding Notes and all
other required documents is at the election and risk of the tendering holders,
but the delivery will be deemed made only when actually received or confirmed
by the Exchange Agent. If Outstanding Notes are sent by mail, it is suggested
that the mailing be made sufficiently in advance of the Expiration Date to
permit delivery to the Exchange Agent prior to midnight, New York City time,
on the Expiration Date.

     See "The Exchange Offer" section of the Prospectus.

2.   Partial Tenders (not applicable to noteholders who tender by book-entry
transfer).

     If less than all of the Outstanding Notes evidenced by a submitted
certificate are to be tendered, the tendering holder(s) should fill in the
aggregate principal amount of Outstanding Notes to be tendered in the box
above entitled "Description of Outstanding Notes--Principal Amount Tendered."
A reissued certificate representing the balance of nontendered Outstanding
Notes will be sent to such tendering holder, unless otherwise provided in the
appropriate box on this Letter, promptly after the Expiration Date. All of the
Outstanding Notes delivered to the Exchange Agent will be deemed to have been
tendered unless otherwise indicated.

3.   Signatures on this Letter; Bond Powers and Endorsements; Guarantee of
Signatures.

     If this Letter is signed by the registered holder of the Outstanding
Notes tendered hereby, the signature must correspond exactly with the name as
written on the face of the certificate without any change whatsoever.


<PAGE>


                                                                             8


     If any tendered Outstanding Notes are owned of record by two or more
joint owners, all of such owners must sign this Letter.

     If any tendered Outstanding Notes are registered in different names on
several certificates, it will be necessary to complete, sign and submit as
many separate copies of this Letter as there are different registrations of
certificates.

     When this Letter is signed by the registered holder or holders of the
Outstanding Notes specified herein and tendered hereby, no endorsements of
certificates or separate bond powers are required. If, however, the Exchange
Notes are to be issued, or any untendered Outstanding Notes are to be
reissued, to a person other than the registered holder, then endorsements of
any certificates transmitted hereby or separate bond powers are required.
Signatures on such certificate(s) must be guaranteed by an Eligible
Institution.

     If this Letter is signed by a person other than the registered holder or
holders of any certificate(s) specified herein, such certificate(s) must be
endorsed or accompanied by appropriate bond powers, in either case signed
exactly as the name or names of the registered holder or holders appear(s) on
the certificate(s) and signatures on such certificate(s) must be guaranteed by
an Eligible Institution.

     If this Letter or any certificates or bond powers are signed by trustees,
executors, administration, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
person should so indicate when signing, and, unless waived by the Company,
proper evidence satisfactory to the Company of their authority to so act must
be submitted.

      Endorsements on certificates for Outstanding Notes or signatures on bond
powers required by this Instruction 3 must be guaranteed by a firm which is a
member of a registered national securities exchange or a member of the
National Association of Securities Dealers, Inc. or by a commercial bank or
trust company having an officer or correspondent in the United States (an
"Eligible Institution").

      Signatures on this Letter need not be guaranteed by an Eligible
Institution, provided the Outstanding Notes are tendered: (i) by a registered
holder of Outstanding Notes (which term, for purposes of the Exchange Offer,
includes any participant in the Book-Entry Transfer Facility system whose name
appears on a security position listing as the holder of such Outstanding
Notes) who has not completed the box entitled "Special Issuance Instructions"
or "Special Delivery Instructions" on this Letter, or (ii) for the account of
an Eligible Institution.

4.  Special Issuance and Delivery Instructions.

     Tendering holders of Outstanding Notes should indicate in the applicable
box the name and address to which Exchange Notes issued pursuant to the
Exchange Offer and/or substitute certificates evidencing Outstanding Notes not
exchanged are to be issued or sent, if different from the name or address of
the person signing this Letter. In the case of issuance in a different name,
the employer identification or social security number of the person named must
also be indicated. Noteholders tendering Outstanding Notes by book-entry
transfer may request that Outstanding Notes not exchanged be credited to such
account maintained at the Book-Entry Transfer Facility as such noteholder may
designate hereon. If no such instructions are given, such Outstanding Notes
not exchanged will be returned to the name or address of the person signing
this Letter.

5.  Tax Identification Number.

     U.S. Federal income tax law generally requires that a tendering holder
whose Outstanding Notes are accepted for exchange must provide the Company (as
payor) with such holder's correct Taxpayer Identification Number ("TIN") on
Substitute Form W-9 below, which in the case of a tendering holder who is an
individual, is his or her social security number. If the Company is not
provided with the current TIN or an adequate basis for an exemption, such
tendering holder may be subject to a $50 penalty imposed by the Internal
Revenue Service. In addition, delivery to such tendering holder of Exchange
Notes may be subject to backup withholding in an amount equal to 31% of all
reportable payments made after the exchange. If withholding results in an
overpayment of taxes, a refund may be obtained.

     Exempt holders of Outstanding Notes (including, among others, all
corporations and certain foreign individuals) are not subject to these backup
withholding and reporting requirements. See the enclosed Guidelines of
Certification of Taxpayer Identification Number on Substitute Form W-9 (the
"W-9 Guidelines") for additional instructions.

     To prevent backup withholding, each tendering holder of Outstanding Notes
must provide its correct TIN by completing the Substitute Form W-9 set forth
below, certifying that the TIN provided is correct (or that such holder is
awaiting a TIN) and that (i) the holder is exempt from backup withholding, or
(ii) the holder has not been notified by


<PAGE>


                                                                             9


the Internal Revenue Service that such holder is subject to backup withholding
as a result of a failure to report all interest or dividends or (iii) the
Internal Revenue Service has notified the holder that such holder is no longer
subject to backup withholding. If the tendering holder of Outstanding Notes is
a nonresident alien or foreign entity not subject to backup withholding, such
holder must give the Company a completed Form W-8, Certificate of Foreign
Status. These forms may be obtained from the Exchange Agent. If the
Outstanding Notes are in more than one name or are not in the name of the
actual owner, such holder should consult the W-9 Guidelines for information on
which TIN to report. If such holder does not have a TIN, such holder should
consult the W-9 Guidelines for information on which TIN to report. If such
holder does not have a TIN, such holder should consult the W-9 Guidelines for
instructions on applying for a TIN, check the box in Part 2 of the Substitute
Form W-9 and write "applied for" in lieu of its TIN. Note: Checking this box
and writing "applied for" on the form means that such holder has already
applied for a TIN or that such holder intends to apply for one in the near
future. If such holder does not provide its TIN to the Company within 60 days,
backup withholding will begin and continue until such holder furnishes its TIN
to the Company.

6.   Transfer Taxes.

     The Company will pay all transfer taxes, if any, applicable to the
transfer of Outstanding Notes to it or its order pursuant to the Exchange
Offer. If however, Exchange Notes and/or substitute Outstanding Notes not
exchanged are to be delivered to, or are to be registered or issued in the
name of, any person other than the registered holder of the Outstanding Notes
tendered hereby, or if tendered Outstanding Notes are registered in the name
of any person other than the person signing this Letter, or if a transfer tax
is imposed for any reason other than the transfer of Outstanding Notes to the
Company or its order pursuant to the Exchange Offer, the amount of any such
transfer taxes (whether imposed on the registered holder or any other persons)
will be payable by the tendering holder. If satisfactory evidence of payment
of such taxes or exemption therefrom is not submitted herewith, the amount of
such transfer taxes will be billed directly to such tendering holder.

      Except as provided in this Instruction 6, it will not be necessary for
transfer tax stamps to be affixed to the Outstanding Notes specified in this
Letter.

7.   Waiver of Conditions.

     The Company reserves the absolute right to waive satisfaction of any or
all conditions enumerated in the Prospectus.

8.   No Conditional Tenders.

     No alternative, conditional, irregular or contingent tenders will be
accepted. All tendering holders of Outstanding Notes, by execution of this
Letter or an Agent's Message in lieu thereof, shall waive any right to receive
notice of the acceptance of their Outstanding Notes for exchange.

9.  Mutilated, Lost, Stolen or Destroyed Outstanding Notes.

     Any holder whose Outstanding Notes have been mutilated, lost, stolen or
destroyed should contact the Exchange Agent at the address indicated above for
further instructions.

10. Requests for Assistance or Additional Copies.

     Questions relating to the procedure for tendering, as well as requests
for additional copies of the Prospectus and this Letter, may be directed to
the Exchange Agent, at the address and telephone number indicated above.

                                   Taxpayer Identification Number (or I am

                              (2)  I am not subject to backup withholding either
                                   because: (a) I am exempt from backup
                                   withholding, or (b) I have not been notified
                                   by the Internal Revenue Service (the "IRS")
                                   that I am subject to backup withholding as a
                                   result of a failure to report all interest or
                                   dividends, or (c) the IRS has notified me
                                   that I am no longer subject to backup
                                   withholding, and

                              SIGNATURE___________________  DATE_______________

You must cross out item (2) of the above certification if you have been notified
by the IRS that you are subject to backup withholding because of underreporting
of interest or dividends on your tax return and you have not been notified by
the IRS that you are no longer subject to backup withholding.



      YOU MUST COMPLETE THE FOLLOWING CERTIFICATE IF YOU CHECKED THE BOX
                       IN PART 2 OF SUBSTITUTE FORM W-9

            CERTIFICATE OF AWAITING TAXPAYER IDENTIFICATION NUMBER

I certify under penalties of perjury that a taxpayer identification number has
not been issued to me, and either (a) I have mailed or delivered an
application to receive a taxpayer identification number to the appropriate
Internal Revenue Service Center or Social Security Administration Office or
(b) I intend to mail or deliver an application in the near future. I
understand that if I do not provide a taxpayer identification number by the
time of the exchange, 31 percent of all reportable payments made to me
thereafter will be withheld until I provide a number.
