                                     PART I
 
ITEM 1. BUSINESS
 
GENERAL
 
     Atlas Air, Inc. ("Atlas" or the "Company") is the world's largest air cargo
outsourcer, with an all Boeing fleet of 747 freighter aircraft. The Company
provides reliable airport-to-airport cargo transportation services throughout
the world to major international air carriers generally under three- to
five-year fixed-rate contracts which typically require that the Company supply
aircraft, crew, maintenance and insurance (the "ACMI Contracts"). The Company's
customers currently include China Airlines Ltd. ("China Airlines"), KLM Royal
Dutch Airlines ("KLM"), Lufthansa Cargo AG ("Lufthansa"), British Airways World
Cargo ("British Airways"), Scandinavian Airlines System ("SAS"), The
International Airline of the United Arab Emirates ("Emirates"), Thai Airways
International Public Company Limited ("Thai Airways"), Fast Air Carrier, S.A.
("Fast Air") and Lineas Aereas Suramericanas, S.A. ("LAS"). The Company is able
to provide efficient, cost effective service to its customers primarily as a
result of its productive work force, the outsourcing of a significant part of
its regular maintenance work on a fixed-cost basis and the advantageous cost
economies realized in the operation of its fleet, comprised solely of Boeing 747
aircraft which are configured for service in long-haul cargo operations.
 
     The Company's fleet currently consists of 17 Boeing 747-200 freighter
aircraft in service and two 747-200 passenger aircraft undergoing conversion to
freighter configuration. The 747-200 passenger aircraft undergoing conversion to
freighter configuration are expected to be placed in service in the second
quarter and early in the third quarter of 1998. On June 9, 1997, the Company
entered into an agreement with The Boeing Company ("Boeing") to purchase 10 new
747-400 freighter aircraft to be powered by engines acquired from General
Electric Company ("GE"), with options to purchase up to 10 additional 747-400
aircraft (the "Boeing Purchase Agreement"). The 747-400 aircraft has
significantly longer range, greater payload capability, lower maintenance costs
and increased fuel efficiency compared to the Boeing 747-200 freighter aircraft.
The Company expects to place the 747-400 aircraft in service with both existing
and prospective customers, who the Company believes should be willing to pay
higher ACMI Contract rates to achieve operating benefits derived from the unique
performance capabilities of the 747-400 aircraft.
 
     The Company attributes its leading market position and continued
opportunities for growth to the following competitive strengths:
 
          Long-Term Customer Contracts Which Provide Revenue Stability. The
     Company's ACMI Contracts with its customers, which accounted for 96% of the
     Company's total operating revenues in 1997, generally provide for its
     customers to guarantee monthly minimum aircraft utilization levels at fixed
     hourly rates and are typically in force for periods of three to five years,
     subject in certain limited cases to early termination provisions. These
     ACMI Contracts typically require that the Company supply aircraft, crew,
     maintenance and insurance and that its customers bear all other operating
     expenses, including fuel and fuel servicing; marketing costs associated
     with obtaining cargo; airport cargo handling; landing fees; ground
     handling, aircraft push-back and de-icing services; and specific cargo and
     mail insurance. The Company's customers are also responsible under these
     contracts for utilizing the cargo capacity of each of the contracted
     aircraft. The ACMI Contracts, therefore, minimize for the Company the load
     factor, yield risk and fuel cost risk traditionally associated with the air
     cargo business and provide the Company with a minimum annual revenue base
     and more predictable profit margins. The Company also periodically engages
     in ad hoc charter or scheduled air service depending on availability of
     aircraft for these uses. In addition, the Company differentiates itself
     from other air cargo companies by not directly or indirectly competing with
     its customers by offering its services to freight forwarders or shippers
     who do business with the Company's customers.
 
          Low Cost Structure. The Company has established itself as a low cost,
     efficient and reliable provider of air cargo transportation primarily due
     to the outsourcing of many of its own required services, the advantageous
     economies of scale realized from the operation of a standardized fleet of
     long-haul Boeing 747-200 aircraft, and its productive work force. The
     uniformity of the 747-200 aircraft fleet allows for
 
                                        2
<PAGE>   3
 
     standardization in maintenance and crew training, resulting in substantial
     cost savings in these areas. In particular, Atlas has advantageous,
     long-term contracts on a fixed-cost per flight hour basis with leading
     maintenance providers such as GE and KLM for a significant portion of its
     on-going aircraft and engine maintenance requirements. As a result of these
     efficiencies, the Company's high service standards and increased airline
     industry pressure to reduce costs, the Company's airline customers have
     determined that outsourcing portions of their air cargo business to the
     Company can be significantly less costly and offer greater operational
     flexibility than expanding their cargo operations by purchasing additional
     aircraft and adding other resources such as personnel and systems. The new
     747-400 aircraft are expected to have even greater operational capabilities
     than the Boeing 747-200 aircraft and will allow the Company to continue to
     maintain its low cost structure. The new aircraft's higher level of
     operational reliability and warrantied condition will result in lower
     maintenance costs during the early years of operation, typically for at
     least five years. In addition, the acquisition of the 10 747-400 freighter
     aircraft will make Atlas the largest operator of this aircraft type to date
     and will enable the Company to achieve economies of scale from the
     standardization in maintenance and crew training.
 
          Expanding Business Base. The growth in demand for air cargo services,
     combined with the lower rate of growth in passenger-airline cargo capacity
     and the continuing pressure on the airline industry to reduce operating
     costs, is expected to provide the Company with the opportunity to expand
     its air cargo outsourcing services. The primary business focus of most of
     the Company's customers is on the transportation of passengers, not air
     cargo. Nevertheless, most passenger airlines have air cargo customers that
     require quick and dependable air cargo service between hubs serviced by
     these carriers. To the extent that airlines have cargo capacity on their
     scheduled flights, which are generally scheduled for the convenience of
     passengers rather than for the needs of air cargo customers, air cargo
     service can be provided by them to meet such demand. However, there is a
     growing trend in the passenger-airline business toward replacing existing
     widebody passenger aircraft and combination passenger/cargo aircraft with
     smaller, more efficient (for passenger operations) twin-engine aircraft
     which have limited cargo space. The Company's customers have therefore
     found that outsourcing to meet their additional cargo transportation needs
     rather than allocating significant resources and expanding their fleet of
     freighter aircraft to effectively service their air cargo customers
     provides a cost-effective alternative for them to maintain and expand that
     portion of their business.
 
          Increasing Cargo Market Share. The Company has successfully increased
     its customer base from a single customer in 1992 to nine customers in 1998.
     In addition, the Company has operated under short-term, seasonal ACMI
     Contracts with Federal Express Corporation ("FedEx"), Kitty Hawk Aircargo,
     Inc. ("Kitty Hawk") and United Parcel Service ("UPS") and anticipates
     providing other short-term, seasonal service. This increased market share
     is a result of the Company's ability to provide a cost-effective service
     which has gained acceptance within the industry due to the Company's
     successful market development efforts. The addition of the 747-400 aircraft
     will provide the Company with the opportunity to increase its market share
     to new and existing customers who have a need for the greater payload,
     extended range and operational reliability of the 747-400, but for whom the
     purchase of a limited number of 747-400 freighter aircraft would not be
     cost-effective. In addition, the 747-400 aircraft will give the Company a
     competitive advantage with new customers who choose to utilize only new or
     relatively new aircraft or are restricted by local regulations limiting the
     operation of older aircraft.
 
INDUSTRY BACKGROUND
 
     While the air cargo industry is highly competitive, the Company believes
that current industry trends are favorable to the continued growth of its
business. The world air cargo market is expected to more than triple over the
next 20 years. It has grown at an average rate of 7.2% per year from 1986 to
1997. The average annual percentage growth through 2017 is expected to average
6.5%, with international air cargo market growth outpacing U.S. domestic growth.
The Company believes this growth has been fueled, in part, by economic growth,
the relaxation of international trade barriers (as indicated by the passage of
the NAFTA and GATT treaties), reductions in the price of shipping by air,
manufacturers' search for low-cost labor in developing countries, and the
increasingly time-sensitive nature of product-delivery schedules due to shorter
product life-
 
                                        3
<PAGE>   4
 
cycles and "just-in-time" inventory management. In addition to growth in the
global air cargo market, the Company expects to benefit from growth in the
export-driven economies of the countries in the Pacific Rim, where the Company
has focused a significant amount of its flight operations. According to a Boeing
report, eastbound and westbound Trans-Pacific cargo volumes grew at an average
annual rate of 6.9% and 14.3%, respectively, between 1986 and 1996, and are
projected to grow at an average annual rate of 8.0% and 8.1% between 1996 and
2016. Similarly, northbound and southbound air cargo volumes between North
America and South America increased at an average annual rate of 9.4% and 8.8%,
respectively, between 1986 and 1996, and are projected to grow at an average
annual rate of over 6.5% from 1996 to 2016. Additionally, eastbound and
westbound North Atlantic air cargo volumes increased at an average annual rate
of 8.4% and 5.9%, respectively, between 1986 and 1996 and are projected to grow
at average annual rates of 6.7% and 7.2%, respectively, from 1996 to 2016. The
Company believes that, as a U.S. certificated "flag" carrier, it is well
positioned to benefit from the progressive expansion of international trade and
the consequential growth in global air cargo markets, particularly in Asia,
South America and Europe, where the Company has concentrated a significant
portion of its resources. The Company has not experienced any adverse impact on
its business as a result of the recent turmoil in the Asian financial markets,
although there can be no assurances that there will not be any future impact.
 
ACMI CONTRACTS
 
     The Company's ACMI Contracts with its customers, which accounted for 96% of
the Company's operating revenues in 1997, typically provide for its customers to
guarantee monthly minimum aircraft utilization levels at fixed hourly rates and
are typically in force for periods of three to five years, subject in certain
limited cases to early termination provisions. These contracts typically require
that the Company supply aircraft, crew, maintenance and insurance and that its
customers bear all other operating expenses, including fuel and fuel servicing;
marketing costs associated with obtaining cargo; airport cargo handling; landing
fees; ground handling, aircraft push-back and de-icing services; and specific
cargo and mail insurance. These contracts, therefore, minimize for the Company
the load factor and yield risk traditionally associated with the air cargo
business. The ACMI Contracts typically require minimum air freight capacity to
be provided to its customers by the Company. All of the Company's revenues, and
virtually all of its costs, are in U.S. dollars, thus avoiding currency risks
normally associated with doing business primarily overseas.
 
     The Company is currently operating under 15 ACMI Contracts: five with China
Airlines, two each with Fast Air and LAS and one each with British Airways,
Emirates, KLM, Lufthansa, SAS and Thai Airways. In most cases, one aircraft is
dedicated under each contract. In addition, the Company recently reached an
agreement with China Airlines for a sixth ACMI Contract, which the Company
expects to commence in the second quarter of 1998. China Airlines, Fast Air and
Lufthansa accounted for approximately 34%, 11% and 8%, of the Company's total
revenues, respectively, for the year ended December 31, 1997. In addition, the
Company has also operated short-term, seasonal ACMI Contracts with FedEx, Kitty
Hawk and UPS and anticipates doing so in the future from time to time.
 
     Certain of the Company's ACMI Contracts allow the Company's customers to
cancel up to a maximum of approximately 5% of the guaranteed hours of aircraft
utilization over the course of a year. The Company's customers most often
exercise such cancellation options early in the first quarter or late in the
fourth quarter of the year, when the demand for air cargo capacity has been
historically lower. The Company has found that such cancellations provide a
timely opportunity for the scheduling of maintenance on its aircraft, to the
extent possible. See "-- Maintenance." The ACMI Contracts are typically in force
for periods of three to five years, subject in certain limited cases to early
termination provisions. The Company believes that its relationships with its
customers are mutually satisfactory, as evidenced by the fact that within the
last three years, it has renewed twelve ACMI Contracts and added nine ACMI
Contracts with its existing customers, although there can be no assurance that
future such contracts will not be canceled in accordance with their terms.
 
     All of the ACMI Contracts provide that each of the Company's aircraft be
deemed to be at all times under the exclusive operating control, possession and
direction of the Company and that, in order to service the routes designated by
the contract, the Company obtain the authority from the governments having
jurisdiction over the route. See "-- Governmental Regulation." Additionally, if
the Company is required to use the customer's "call sign" in identifying itself
throughout its route, the customer must also have obtained
 
                                        4
<PAGE>   5
 
underlying authority from the governments having jurisdiction over the route.
Therefore, the Company's route structure is limited to areas in which it can
gain access from the appropriate governments.
 
OTHER FLIGHT OPERATIONS
 
     To the extent the Company has available excess aircraft capacity at any
time, it will seek to obtain ad hoc charter service contracts, which the Company
believes are generally readily available. In addition, in the past the Company
has provided service to FedEx, Kitty Hawk and UPS pursuant to short-term,
seasonal ACMI Contracts during periods of excess aircraft capacity.
 
SALES AND MARKETING
 
     From its offices in Colorado, New York and Miami, the Company services its
air cargo customers and solicits ACMI Contract business. The Company's efforts
to obtain new ACMI Contract business focus principally on international airlines
with established air cargo customers, high operating costs and hub and spoke
systems which gather cargo at a particular location and which have the need for
long-distance capacity to move such cargo to another distribution point. On
occasion, the Company may utilize independent cargo brokers to obtain new ACMI
Contracts. The Company markets its services by guaranteeing its customers a
reliable, low-cost dedicated aircraft with the capacity to ensure the efficient
linkage of such customers' distribution points without the customers having to
purchase and maintain additional aircraft, schedule additional flights and add
other resources. The Company expects to place the 747-400 aircraft in service
with both existing and prospective customers, which the Company believes should
be willing to pay higher ACMI Contract rates to achieve operating benefits
derived from the unique performance capabilities of the 747-400 aircraft such as
its longer range, greater payload and increased fuel efficiency.
 
MAINTENANCE
 
     Due to the average age of the Company's Boeing 747-200 fleet, it is likely
that the aircraft will require greater maintenance than newer aircraft such as
the 747-400 aircraft. See "-- Aircraft." Aircraft maintenance includes, among
other things, routine daily maintenance, maintenance every six weeks (an "A
Check"), significant maintenance work every 18 months (a "C Check") and major
maintenance events every five years or 25,000 flight hours, whichever comes
later if the aircraft is over the age of 18 years, or every six years or 25,000
flight hours, whichever comes later for aircraft under the age of 18 years, with
a maximum interval in either case of nine years (a "D Check"). The Company
attempts to schedule major maintenance on its aircraft in the first quarter of
the calendar year, when the demand for air cargo capacity has historically been
lower, taking advantage of cancellations of flights by the Company's customers
that generally occur most frequently during these periods.
 
     Pursuant to a maintenance contract with KLM (the "Maintenance Contract") in
effect until January 2005, a significant part of the regular maintenance
(principally C Checks and engine overhauls, excluding D Checks) of certain of
the Company's aircraft and their GE engines is undertaken by KLM, primarily at
its maintenance base located at Schiphol International Airport in Amsterdam, The
Netherlands. KLM supplies engineering and diagnostic testing for each aircraft
and its components in compliance with the Federal Aviation Administration (the
"FAA") and other applicable regulations. The Maintenance Contract provides that
KLM, subject to certain terms and conditions, will perform repairs and
maintenance of the Company's aircraft on the same basis and order of priority as
repairs to its own fleet. Such service is provided to the Company at a cost, for
which a large part is a fixed rate per flight hour, subject to a 3.5% annual
escalation factor for the first five years. Pratt & Whitney Corporation ("P&W")
engines are serviced elsewhere, each at a cost based upon the actual time and
material necessary for such service. Under the terms of the Maintenance
Contract, in the event that the Company wishes to maintain more than 12 of its
aircraft under such contract, the terms of the contract are subject to
adjustment by KLM. Twelve of the Company's aircraft are currently subject to the
Maintenance Contract.
 
     In June 1996, the Company entered into a ten year engine maintenance
agreement with GE for the engine maintenance of up to 15 aircraft powered by
CF6-50E2 engines at a fixed rate per flight hour, subject
 
                                        5
<PAGE>   6
 
to an annual formula increase. The agreement commenced in the third quarter of
1996 with the acceptance of engines associated with aircraft acquired in the
third and fourth quarter of 1996. Effective in the year 2000, the Company has an
option to add not less than 40 engines to the program.
 
     During the initial operating period, the 747-400 aircraft's airframe and
engines will be covered under manufacturer's warranties. As a result, the
Company does not expect to incur significant maintenance expense in connection
with the 747-400 aircraft during the warranty period. In addition, the 747-400
aircraft's limited maintenance requirements will provide a higher operational
reliability with lower maintenance costs during the early years of operation,
typically for at least five years. The Company will incur expenses associated
with routine daily maintenance of both the airframe and the engines. In
connection with the GE engine purchase agreement, the Company is currently in
negotiations with GE to provide ongoing maintenance on the 747-400 aircraft
engines.
 
     The Company believes that fixed-cost contracts provide the most efficient
means of ensuring the continued service of its aircraft fleet and the most
reliable way by which to predict its maintenance costs; however, the Company
believes it is more cost effective for routine line maintenance and A Checks to
be performed on a time and material basis due to the frequency of such
maintenance. The Company also has a contract with B.F. Goodrich Co. to perform
maintenance on its brakes and for the replacement of tires.
 
     The Company has an agreement, subject to acceptable rates, terms and
conditions, with Linee Aeree Italiane S.p.A. ("Alitalia") to utilize, or find
other parties to utilize, an amount of Alitalia's maintenance services with an
aggregate cost of $25 million over a five-year period ending in June 2000.
 
GOVERNMENTAL REGULATION
 
     Under the Federal Aviation Act of 1958 (the "Aviation Act"), the Department
of Transportation (the "DOT") and the FAA exercise regulatory authority over the
Company. The DOT's jurisdiction extends primarily to economic issues related to
the air transportation industry, including, among other things, air carrier
certification and fitness, insurance, certain leasing arrangements, the
authorization of proposed scheduled and charter operations, tariffs, consumer
protection, unfair methods of competition, unjust discrimination and deceptive
practices. The FAA's regulatory authority relates primarily to air safety,
including aircraft certification and operations, crew licensing/training and
maintenance standards.
 
     To provide air cargo transportation services under long-term contracts with
major international airlines, the Company relies primarily on its worldwide
charter authorities. The Company requires separate DOT and FAA approval for each
long-term ACMI Contract. In addition, FAA approval is required for each of the
Company's short-term, seasonal ACMI Contracts.
 
     In order to engage in its air transportation business, the Company is
required to maintain a Certificate of Public Convenience and Necessity (a
"CPCN") from the DOT. Prior to issuing a CPCN, the DOT examines a company's
managerial competence, financial resources and plans and compliance disposition
in order to determine whether a carrier is fit, willing and able to engage in
the transportation services it has proposed to undertake, and whether a carrier
conforms with the Aviation Act requirement that the transportation services
proposed are consistent with the public convenience and necessity. Among other
things, a company holding a CPCN must qualify as a United States citizen, which
requires that it be organized under the laws of the United States or a State,
Territory or Possession thereof; that its Chief Executive Officer and at least
two-thirds of its Board of Directors and other managing officers be United
States citizens; that not more than 25% of its voting stock be owned or
controlled, directly or indirectly, by foreign nationals; and that it not
otherwise be subject to foreign control. The DOT may impose conditions or
restrictions on such a CPCN.
 
     The DOT has issued the Company a CPCN to engage in interstate and overseas
air transportation of property and mail, and a CPCN to engage in foreign air
transportation of property and mail between the U.S. and Taiwan. Both CPCNs are
subject to standard terms, conditions and limitations. By virtue of holding
those CPCNs, the Company possesses worldwide charter authorities. It also holds
limited-term DOT exemption authority to engage in scheduled air transportation
of property and mail between certain points in the U.S. and Hong Kong.

     International air services are generally governed by a network of bilateral
civil air transport agreements in which rights are exchanged between
governments, which then select and designate air carriers authorized to exercise
such rights. Insofar as scheduled service is involved, bilateral agreements may
prohibit services to certain countries. For countries in which service is
authorized, these bilateral agreements specify the city-pair markets that may be
served; may restrict the number of carriers that may be designated; may provide
for prior approval by one or both governments of the prices the carriers may
charge; may limit frequencies or the amount of capacity to be offered in the
market; and, in various other ways, may impose limitations on the operations of
air carriers. To obtain authority under a bilateral agreement, it is often
necessary to compete against other carriers in a DOT proceeding. At the
conclusion of the proceeding, the DOT awards all route authorizations. The
provisions of bilateral agreements pertaining to charter services vary
considerably from country to country. Some agreements limit the number of
charter flights that carriers of each country may operate. The Company is
subject to various international bilateral air services agreements between the
U.S. and the countries to which the Company provides service. The Company also
operates on behalf of foreign flag air carriers between various foreign points
without serving the U.S. These services are subject to the bilateral agreements
of the respective governments. Furthermore, these services require FAA approval
but not DOT approval. The Company must obtain permission from the applicable
foreign governments to provide service to foreign points.
 
     The Company has obtained an operating certificate issued by the FAA
pursuant to Part 121 of the Federal Aviation Regulations. The FAA has
jurisdiction over the regulation of flight operations generally, including the
licensing of pilots and maintenance personnel; the establishment of minimum
standards for training and retraining; maintenance of technical standards for
flight, communications and ground equipment; security programs; and other
matters affecting air safety. In addition, the FAA mandates certain
recordkeeping procedures. The Company must obtain and maintain FAA certificates
of airworthiness for all of its aircraft. The Company's aircraft, flight
personnel and flight and emergency procedures are subject to periodic
inspections and tests by the FAA. All air carriers operating to, from or within
the United States are subject to the strict scrutiny of the FAA to ensure proper
compliance with FAA regulations.
 
     The DOT and the FAA have authority under the Aviation Safety and Noise
Abatement Act of 1979, as amended and recodified, and under the Airport Noise
and Capacity Act of 1990, to monitor and regulate aircraft engine noise. All of
the Company's existing fleet of aircraft comply with Stage III Standards -- the
highest standard issued by the FAA.
 
     Under the FAA's Directives issued under its "Aging Aircraft" program, the
Company is subject to extensive aircraft examinations and may be required to
undertake structural modifications to address the problem of corrosion and
structural fatigue. In November 1994, Boeing issued Nacelle Strut Modification
Service Bulletins which have been converted into Directives by the FAA. Twelve
of the Company's Boeing 747-200 aircraft will have to be brought into compliance
with such Directives within the next three years at an estimated cost of
approximately $6.0 million. As part of the FAA's overall Aging Aircraft program,
it has issued Directives requiring certain additional aircraft modifications to
be accomplished prior to the aircraft reaching 20,000 cycles. The average cycle
time for the 17 aircraft in service is approximately 12,000 cycles and the
average cycles operated per year is approximately 800 cycles. The Company
estimates that the modification costs per aircraft will range between $2 million
and $3 million. Between now and the year 2000, only one aircraft is expected to
reach the 20,000 cycle limit and nine additional aircraft will require
modification prior to the year 2009. The remaining seven aircraft have already
undergone such modifications. The two aircraft undergoing modification to
freighter configuration will receive the Nacelle Strut Modification as part of
the freighter conversion. Other Directives have been issued that require
inspections and minor modifications to Boeing 747-200 aircraft. It is possible
that additional Directives applicable to the types of aircraft or engines
included in the Company's fleet could be issued in the future, the cost of which
could be substantial.
 
     The Company is also subject to the regulations of the Environmental
Protection Agency regarding air quality in the U.S. With respect to aircraft
that it operates, the Company meets the fuel venting requirements and smoke
emissions standards established by the Environmental Protection Agency.

COMPETITION
 
     The market for air cargo services is highly competitive. A number of
airlines currently provide services for themselves and for others similar to the
services offered by the Company and new airlines may be formed that would also
compete with the Company. Such airlines may have substantially greater financial
resources than the Company. The Company believes that the most important factors
for competition in the air cargo business are the range, payload and cubic
capacities of the aircraft and the price, flexibility, quality and reliability
of service. The ability of the Company to achieve its strategic plan depends in
part upon its success in convincing major international airlines that
outsourcing some portion of their air cargo business remains more cost-
effective than undertaking cargo operations with their own incremental capacity
and resources and the ability of the Company to obtain higher ACMI Contract
rates in connection with the 747-400 aircraft compared to those currently
obtained in connection with existing Boeing 747-200 aircraft. The Company
believes that such higher rates will be obtainable as a result of the unique
operating benefits associated with the 747-400 aircraft. These operational
benefits include a longer range, greater payload capability and increased fuel
efficiency relative to the Boeing 747-200 aircraft.
 
FUEL
 
     Although fuel costs are typically the largest operating expense for
airlines, the Company has limited exposure to the fluctuation of fuel costs and
disruptions in supply as a result of its ACMI Contracts, which require the
customers to provide fuel for the aircraft. However, an increase in fuel costs
could reduce the Company's cost advantages because of its older Boeing 747-200
aircraft fleet, which are not as fuel-efficient as newer cargo aircraft such as
the 747-400 aircraft. In addition, to the extent the Company operates scheduled
cargo or ad hoc charter services, or positions its aircraft, it is responsible
for fuel and other costs that are normally borne by the customers under the ACMI
Contracts. In 1997, approximately 2% of the Company's block hours represented
scheduled cargo, ad hoc charter services or positioning its aircraft for its own
account. The Company may, at times, have excess capacity in which case it may
deploy such aircraft in scheduled cargo or ad hoc charter services.
 
EMPLOYEES
 
     As of March 1, 1998, the Company had 676 employees, 382 of whom were air
crew members. The Company expects to hire additional pilots in 1998 associated
with the delivery of additional aircraft, including the 747-400 aircraft. The
Company maintains a comprehensive training program for its pilots in compliance
with FAA requirements in which each pilot regularly attends update programs. The
Company believes that its current training program can be sufficiently modified
to provide training required for pilots for the 747-400 aircraft. In addition,
as part of the Boeing Purchase Agreement, to defray a portion of the costs,
Boeing will train a limited number of the Company's pilots and crew to be
assigned to the 747-400 aircraft. However, the Company may incur incremental
costs associated with ongoing training with regard to the 747-400 aircraft.
 
     The Company believes that its employees' participation in the growth and
profitability of its business is essential to maintain its productivity and low
cost structure, and has therefore established programs for that purpose such as
a profit sharing plan, a stock purchase plan, and a Company percentage
contribution of the employee deferral contribution to a retirement plan
(Internal Revenue Code of 1986, as amended, Section 401(k) plan). Such programs
are designed to allow employees to share financially in the Company's success
and to augment base salary levels and retirement income. The Company considers
its relations with its employees to be good.
 
     The Company's labor relations are covered under Title II of the Railway
Labor Act of 1926, as amended, and are subject to the jurisdiction of the
National Mediation Board. None of the Company's employees is subject to a
collective bargaining agreement; however, many airline industry employees are
subject to such agreements and the Company's employees have been and are
routinely solicited by union representatives seeking to organize them. In
January 1998, the Company's pilots rejected union representation by the Air Line
Pilots Association.

INSURANCE
 
     The Company is vulnerable to potential losses which may be incurred in the
event of an aircraft accident. Any such accident could involve not only repair
or replacement of a damaged aircraft and its consequent temporary or permanent
loss from service, but also potential claims involving injury to persons or
property. The Company is required by the DOT to carry liability insurance on
each of its aircraft, and each of the Company's aircraft leases and ACMI
Contracts also requires the Company to carry such insurance. While the Company
carries this insurance, any extended interruption of the Company's operations
due to the loss of an aircraft could have a material adverse effect on the
Company. The Company currently maintains public liability and property damage
insurance and aircraft hull and liability insurance for each of the aircraft in
the fleet in amounts consistent with industry standards. The Company maintains
baggage and cargo liability insurance if not provided by its customers under
ACMI Contracts. Although the Company believes that its insurance coverage is
adequate, there can be no assurance that the amount of such coverage will not be
changed upon renewal or that the Company will not be forced to bear substantial
losses from accidents. Substantial claims resulting from an accident could have
a material adverse effect on the Company's financial condition and could affect
the ability of the Company to obtain insurance in the future. The Company
believes that it has good relations with its insurance providers.
 
ITEM 2. PROPERTIES
 
AIRCRAFT
 
     The Company's utilization of Boeing 747 aircraft provides significant
marketing advantages because these aircraft, relative to most other cargo
aircraft that are commercially available, have higher maximum payload and cubic
capacities, and longer range. The uniformity of the Company's current Boeing
747-200 aircraft fleet allows for standardization in maintenance and crew
training, resulting in substantial cost savings in these areas. The new 747-400
aircraft are expected to have greater operational capabilities than the 747-200
aircraft and will allow the Company to continue to maintain its low cost
structure despite their higher acquisition cost. The new aircraft's limited
maintenance requirements will provide a higher level of operational reliability
with lower maintenance costs during the early years of operation, typically for
at least five years. In addition, the acquisition of the 10 747-400 freighter
aircraft will make Atlas the largest operator of this aircraft type to date and
will enable the Company to capitalize on economies of scale from the
standardization in maintenance and crew training.
 
     In January 1998, the Company's leases for five Boeing 747-200 from FedEx
expired and the aircraft were returned. The Company expects to make up this loss
of capacity through the utilization of the two aircraft in conversion and with
the delivery of five 747-400 aircraft during the second half of 1998.
 
     The following table describes, as of March 16, 1998, the Company's existing
fleet, aircraft currently undergoing passenger to freighter modification and the
747-400 aircraft subject to the Boeing Purchase Agreement.

(3) These passenger aircraft are powered by GE engines and are currently
    undergoing conversion to freighter configuration by Boeing. The aircraft are
    expected to be placed in service in the second quarter and early in the
    third quarter of 1998.
 
(4) The Company has agreed to purchase 10 new Boeing 747-400 freighter aircraft,
    with options to purchase an additional 10 aircraft. The first 10 aircraft
    are scheduled to be delivered as follows: five in 1998, two in 1999 and
    three in 2000. See "-- 747-400 Aircraft Acquisition." These aircraft will be
    powered by GE engines. Debt financing for the first five aircraft has been
    secured through the EETCs (see "ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS
    OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS -- Recent Developments").
    In addition, the Company may arrange for tax-oriented long-term leases on
    some or all of these aircraft.
 
     The Company has been successful in obtaining new customers, or additional
arrangements with existing customers coincident with the delivery of aircraft
into the fleet, or soon thereafter. However, from time to time, the Company
accepts delivery of aircraft that have not been committed to a particular ACMI
Contract. These aircraft have been utilized temporarily as replacement aircraft
during scheduled and unscheduled maintenance of other aircraft, as well as for
ad hoc charter arrangements. Although the Company intends to have new ACMI
Contracts in place upon delivery of aircraft, including the 747-400 aircraft,
there can be no assurance that such arrangements will have been made.
 
     From time to time, the Company engages in discussions with third parties
regarding possible acquisitions of aircraft that could expand the Company's
operations. The Company is in discussions with third parties for the possible
acquisition of additional aircraft for delivery in 1998 and beyond.
 
747-400 AIRCRAFT ACQUISITION
 
     In June 1997, the Company entered into the Boeing Purchase Agreement to
purchase 10 new 747-400 freighter aircraft to be powered by GE engines. The
747-400 freighter aircraft are currently scheduled to be delivered as follows:
five in 1998, two in 1999 and three in 2000. Due to production problems at
Boeing, the Company believes that each of the 1998 delivery positions of the
747-400 aircraft may be delayed up to 60 days. While Boeing will compensate the
Company for defined delays in delivery of the 747-400 aircraft, any such delays
may adversely impact the Company's ability to initiate service with prospective
customers in a timely fashion. The Boeing Purchase Agreement also provides the
Company with options to purchase up to 10 additional 747-400 freighter aircraft
for delivery from 1999 through 2002. As a result of the Company being the
largest purchaser of 747-400 freighter aircraft to date, it was able to
negotiate from Boeing and GE a significant discount off the aggregate list price
of $1.7 billion for the 10 747-400 freighter aircraft, four installed engines
per aircraft and five spare engines. In addition, the Company also obtained
certain ancillary products and services at advantageous prices.
 
FACILITIES
 
     The Company's principal executive offices are located in a 7,000 square
foot office building owned by the Company at 538 Commons Drive, Golden,
Colorado. The Company also rents 2,500 square feet of office space in an
adjacent building.
 
     The Company presently occupies a 22,000 square foot facility located at
John F. Kennedy International Airport ("JFK"). This facility includes
administrative offices, maintenance work areas and hangar and parts storage
facilities, as well as flight dispatch operations. The Company occupies this
facility pursuant to a lease agreement with Japan Airlines ("JAL") for a
five-year period with two five-year renewal rights from JAL, which began on June
1, 1995, at a monthly rate of approximately $55,000. The Company believes the
JAL facility is adequate to support the near term growth in operations that will
result from the anticipated acquisition of additional aircraft. In addition, the
Company leases 7,750 square feet of warehouse space at JFK for the storage of
aircraft components, tires and other aircraft related equipment at a monthly
lease rate of $5,000. The initial lease term expires at the end of August 1999
and provides for two one-year renewal option periods beginning September 1,
1999.

     Due to increased operations at Miami International Airport, the Company
entered into a month-to-month office lease and a month-to-month warehouse lease
with Dade County, Florida in March 1997 at a combined monthly lease rate of
approximately $6,000. The leased warehouse space is used to store aviation
equipment and aircraft components used to maintain aircraft operated by the
Company.
 
ITEM 3. LEGAL PROCEEDINGS
 
     On February 24, 1997, the Company filed a complaint for declaratory
judgment in the Colorado District Court, Jefferson County against Israel
Aircraft Industries Ltd. ("IAI") for mechanical problems the Company experienced
with respect to an aircraft the Company sub-leased from IAI. The Company is
seeking approximately $4 million in damages against IAI to be offset by the
amount, if any, the Company owes IAI pursuant to the sub-lease. IAI had the case
removed to the U.S. District Court, District of Colorado on April 21, 1997 and
has filed counterclaims alleging damages of approximately $9 million based on
claims arising from the sub-lease. The Company intends to vigorously defend
against all of IAI's claims.
 
     In March 1997, Air Support International, Inc. ("ASI") filed a complaint
against the Company in the U.S. District Court, Eastern District of New York
alleging actual and punitive damages of approximately $13.5 million arising from
the Company's refusal to pay commissions which ASI claims it is owed for
allegedly arranging certain ACMI Contracts. The Company intends to vigorously
defend against all of ASI's claims.
 
     While the Company is from time to time involved in litigation in the
ordinary course of its business, there are no other material legal proceedings
pending against the Company or to which any of its property is subject.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
     No matters were submitted to a vote of the Company's security holders
during the fourth quarter of 1997.

RESULTS OF OPERATIONS
 
     The cargo operations of the Company's airline customers are seasonal in
nature, with peak activity occurring traditionally in the second half of the
year, and with a significant decline occurring in the first quarter. This
decline in cargo activity is largely due to the decrease in shipping that occurs
following the December and January holiday seasons associated with the
celebration of Christmas and the Chinese New Year. Certain of the Company's
customers have, in the past, elected to use that period of the year to exercise
their contractual options to cancel a limited number (generally not more than 5%
per year) of guaranteed hours with the Company, and are expected to continue to
do so in the future. As a result, the Company's revenues typically decline in
the first quarter of the year as its contractual aircraft utilization level
temporarily decreases. The Company seeks to schedule, to the extent possible,
its major aircraft maintenance activities during this period to take advantage
of any unutilized aircraft time.

     The aircraft acquisitions, lease arrangements and modification schedule are
described in Note 6 of the Company's December 31, 1997 Consolidated Financial
Statements. The timing of when an aircraft enters the Company's fleet can affect
not only annual performance, but can make quarterly results vary, thereby
affecting the comparability of operations from period to period.
 
     The tables below set forth selected financial and operating data for the
four quarters of the years ended December 31, 1997, 1996 and 1995 (dollars in
thousands).

  1997 Compared to 1996
 
     Operating Revenues and Results of Operations. Total operating revenues for
the year ended December 31, 1997 increased to $401.0 million compared to $315.7
million for 1996, an increase of approximately 27%. The average number of
aircraft in the Company's fleet during 1997 was 19.5 compared to 14.7 during
1996. Total block hours for 1997 were 75,254 compared to 59,445 for 1996, an
increase of approximately 27%, principally reflecting the increase in the size
of the Company's fleet. Revenue per block hour increased by approximately .4% to
$5,329 for 1997 compared to $5,310 for 1996. The Company's operating results
decreased from an $88.1 million operating profit in 1996 to a $56.0 million
operating profit in 1997, primarily due to the largely non-cash charge to
earnings of $27.1 million in the second quarter of 1997. The after-tax effect of
this second quarter charge was substantially offset by the after-tax effect of
the extraordinary gain on
 
                                       13
<PAGE>   14
 
early extinguishment of debt in the same quarter of 1997. Net income of $37.8
million for 1996 declined to a net income of $23.4 million for 1997, primarily
due to the increase in interest expense associated with the increase in aircraft
in service year over year and the higher maintenance costs with respect to the
aircraft sub-leased from FedEx.
 
     Operating levels increased during the second quarter of 1997 as a result of
placing in service two additional aircraft upon completion of their respective
cargo modifications by Boeing, one in March 1997 and one in May 1997. In
addition, the Company placed in service the fifth FedEx aircraft in April 1997.
In August 1997 and at the end of September 1997, the Company took delivery of
the fifth and sixth Thai Aircraft, respectively, upon completion by Boeing of
its modification to cargo configuration. At the end of 1997, the Company removed
from revenue service the five aircraft sub-leased from FedEx in preparation for
the return of these aircraft to FedEx in the first quarter of 1998, as provided
for in the sub-leases.
 
     The Company's operating levels increased moderately during 1997 as a result
of these aircraft acquisitions. Block hours increased from 15,443 in the first
quarter of 1997 to 22,333 in the fourth quarter of 1997, reflecting the growth
in the average fleet size from 17.2 aircraft to 20.9 aircraft for the two
periods. Total operating revenue increased from $82.0 million in the first
quarter to $120.9 million in the fourth quarter, representing slightly higher
block hour rates for the fourth quarter compared to those of the first quarter
of 1997, primarily due to the seasonality of the business of the Company's
customers. The Company achieved $27.8 million operating income and $9.1 million
net income in the fourth quarter of 1997, compared to $17.1 million operating
income and $5.0 million net income in the first quarter of 1997.
 
     In the second quarter of 1997, the Company recorded a largely non-cash
charge of $27.1 million to operating income. This charge included the write-off
of the Company's remaining balance sheet investment in the five aircraft
sub-leased from FedEx, as well as the establishment of certain reserves
associated with costs necessary to return the aircraft in the first quarter of
1998 and other non-recurring items. Excluding this charge, operating income was
$83.1 million for 1997 compared to $88.1 million for 1996, or a decrease of
approximately 6%. There were an average of 4.4 aircraft subleased from FedEx
operating in 1997 compared to an average of 1.7 aircraft sub-leased from FedEx
operating in 1996. Maintenance costs with respect to the FedEx aircraft were
substantially higher than for the rest of the Company's fleet. In addition, the
Company incurred $1.2 million of costs in the first quarter of 1997 related to
the return of two leased aircraft to their respective lessors. In the second
quarter of 1997, the realization of an after-tax extraordinary gain of $16.7
million, resulting from the receipt of a prepayment incentive credit associated
with the refinancing of approximately $228 million of indebtedness during the
second quarter, for the most part offset the $17.2 million after-tax impact of
the non-recurring charge discussed above.
 
     Operating Expenses. The Company's principal operating expenses include
flight crew salaries and benefits; other flight-related expenses; maintenance;
aircraft and engine rentals; fuel costs and ground handling; depreciation and
amortization; and selling, general and administrative expenses.
 
     Flight crew salaries and benefits include all such expenses for the
Company's pilot work force. Flight crew salaries and benefits increased to $30.2
million in 1997 compared to $25.0 million in 1996, due to increases in the
number of aircraft in the Company's fleet and aircraft block hours. While actual
expense increased by approximately 21% during 1997, on a block hour basis this
expense declined by approximately 5% to $401 per block hour for 1997 from $421
per block hour for 1996. This reduction was due to increased efficiency in
staffing levels and scheduling resulting from the increased level of operations.
 
     Other flight-related expenses include hull and liability insurance on the
Company's fleet of Boeing 747-200 aircraft, crew travel and meal expenses,
initial and recurring crew training costs and other expenses necessary to
conduct its flight operations.
 
     Other flight-related expenses increased to $28.8 million in 1997 compared
to $27.4 million in 1996, or approximately 5%. The impact of the larger fleet
size for 1997 compared to the prior year was partially offset by a reduction in
the Company's aircraft hull and liability insurance rates based on its increased
size and favorable operating history. As a result of this and other operating
efficiencies, on a block hour basis, other
 
                                       14
<PAGE>   15
 
flight-related expenses declined by approximately 17% to $383 per block hour for
1997 compared to $461 per block hour for 1996.
 
     Maintenance expenses include all expenses related to the upkeep of the
aircraft, including maintenance, labor, parts, supplies and maintenance
reserves. The costs of C Checks, D Checks and engine overhauls not otherwise
covered by maintenance reserves are capitalized as they are incurred and
amortized over the life of the maintenance event. In addition, in January 1995
the Company contracted with KLM for a significant part of its regular
maintenance operations and support on a fixed cost per flight hour basis.
Effective October 1996, certain aircraft engines were accepted into the GE
engine maintenance program, also on a fixed cost per flight hour basis, pursuant
to a 10 year maintenance agreement.
 
     Maintenance expense increased to $123.8 million in 1997 from $84.3 million
in 1996, or approximately 47%, partially due to the increase in the Company's
average fleet size and partially due to the higher maintenance costs with
respect to the aircraft sub-leased from FedEx. On a block hour basis,
maintenance expense increased year over year by approximately 16%, primarily due
to higher maintenance costs associated with the aircraft sub-leased from FedEx.
 
     Aircraft and engine rentals include the cost of leasing aircraft and spare
engines, as well as the cost of short-term engine leases required to replace
engines removed from the Company's aircraft for either scheduled or unscheduled
maintenance and any related short-term replacement aircraft lease costs.
 
     Aircraft and engine rentals were $31.6 million in 1997 compared to $27.3
million in 1996, or an increase of approximately 16%, of which approximately
$2.6 million was due to higher lease rates in 1997 compared to 1996 and $3.1
million was due to an additional .5 aircraft leased in 1997 over 1996. This
increase was partially offset by a $1.4 million decrease in engine rentals year
over year, due to additional spare engines purchased by the Company in 1997.
 
     Because of the nature of the Company's ACMI contracts with its airline
customers, under which the Company is responsible only for the ownership cost
and maintenance of the aircraft and for supplying aircraft crews and insurance,
the Company's airline customers bear all other operating expenses, including
fuel and fuel servicing; marketing costs associated with obtaining cargo;
airport cargo handling; landing fees; ground handling; aircraft push-back and
de-icing services; and specific cargo and mail insurance. As a result, the
Company incurs fuel and ground handling expenses only when it operates on its
own behalf, either in scheduled services, for ad hoc charters or for ferry
flights. Fuel expenses for the Company's non-ACMI contract services include both
the direct cost of aircraft fuel as well as the cost of delivering fuel into the
aircraft. Ground handling expenses for non-ACMI contract service include the
costs associated with servicing the Company's aircraft at the various airports
to which it operates as well as other direct flight related costs.
 
     Fuel and ground handling costs increased to $10.8 million for 1997 compared
to $10.6 million for 1996, or an increase of approximately 3%. This was due to
higher fuel prices in 1997 compared to 1996, partially offset by the relative
decrease in scheduled service, charter and other non-ACMI block hours to 1,787
block hours in 1997 from 2,042 block hours in 1996.
 
     Depreciation and amortization expense includes depreciation on aircraft,
spare parts and ground equipment, and the amortization of capitalized major
aircraft maintenance and engine overhauls.
 
     Depreciation and amortization expense increased to $42.9 million in 1997
from $25.5 million in 1996, or approximately 68%. This increase reflected an
increase of approximately 50% in owned aircraft, an approximate two-fold
increase in owned spare engines and an increase of approximately 100% in spare
parts for 1997 over 1996. In addition, Other Revenues include $1.5 million of
depreciation for 1997, associated with the net lease of two owned aircraft which
were in passenger configuration.
 
     Other operating expenses include salaries, wages and benefits for all
employees other than pilots; accounting and legal expenses; supplies; travel and
meal expenses, excluding those of the aircraft crews; commissions; and other
miscellaneous operating costs.
 
     Other operating expenses increased to $49.8 million in 1997 from $27.5
million in 1996, or approximately 81%, reflecting the increase in the Company's
operations. On a block hour basis, these expenses increased to
                                       15
<PAGE>   16
 
$661 per block hour in 1997 from $462 per block hour in 1996, or approximately
43%. This increase in cost was due primarily to additional personnel and other
resources necessary to properly manage the Company's increased operations and to
prepare for the introduction of the 747-400 aircraft.
 
     Other income (expense) consists of interest income and interest expense.
Interest income for 1997 was $7.4 million compared to $7.1 million for 1996, due
to achieving higher interest rates in 1997 compared to 1996 on a slightly lower
short-term investment level in 1997 compared to 1996. Interest expense increased
to $52.8 million in 1997 from $35.6 million in 1996, or approximately 49%,
primarily resulting from an increase of approximately 50% in financed flight
equipment between these periods.
 
     Income Taxes. Pursuant to the provisions of SFAS No. 109 "Accounting for
Income Taxes," the Company has recorded a tax provision based on tax rates in
effect during the period. Accordingly, the Company accrued taxes at the rate of
36.5% during 1997 and 1996. Due to significant capital costs, which are
depreciated at an accelerated rate for tax purposes, a majority of the Company's
tax provision in these periods is deferred.
 
  1996 Compared to 1995
 
     Operating Revenues and Results of Operations. Total operating revenues for
the year ended December 31, 1996 increased to $315.7 million compared to $171.3
million for 1995, an increase of approximately 84%. The average number of
aircraft in the Company's fleet during 1996 was 14.7, compared to 7.7 during
1995. Total block hours for 1996 were 59,445 compared to 33,265 for 1995, an
increase of approximately 79%. Revenue per block hour increased by 3% to $5,310
for 1996 compared to $5,149 for the year-earlier period reflecting a slight
increase in the level of charter and scheduled service hours. While charter and
scheduled service activity provides a higher revenue rate per block hour, costs
are also higher due to fuel and ground handling costs which the Company must
bear. The Company's operating results improved from a $42.7 million operating
profit for 1995 to an operating profit of $88.1 million for 1996, or
approximately 106%. Net income of $17.8 million for 1995 improved to a net
income of $37.8 million for 1996, or approximately 112%.
 
     Operating levels increased during the first quarter of 1996 as a result of
placing in service four additional aircraft. In January 1996, the Company placed
in service one aircraft upon completion of its cargo modification by Hong Kong
Aircraft Engineering Company. Two additional aircraft were re-delivered to the
Company upon completion of their modification by Boeing in March 1996. Finally,
at the close of the first quarter, the Company took delivery of the first
aircraft sub-leased from FedEx. During the third quarter of 1996, the Company
placed in service the next three aircraft sub-leased from FedEx. At the end of
the third quarter the Company took delivery of a Boeing 747-200 passenger
aircraft acquired from Thai Airways upon completion by Boeing of its
modification to cargo configuration. In the fourth quarter of 1996, a second
Boeing 747-200 passenger aircraft acquired from Thai Airways was placed in
service upon its delivery by Boeing subsequent to modification to cargo
configuration. At the end of 1996, two leased aircraft were taken out of service
for required maintenance prior to re-delivery to the lessors.
 
     The Company's operating levels increased significantly during 1996 as a
result of these aircraft acquisitions. Block hours increased from 11,125 in the
first quarter of 1996 to 18,803 in the fourth quarter of 1996, relative to the
growth in average fleet size from 10.8 aircraft to 18.4 aircraft for the two
periods. Total operating revenue increased from $58.6 million in the first
quarter to $104.7 million in the fourth quarter, representing slightly higher
block hour rates for the fourth quarter compared to those of the first quarter
of 1996, primarily due to the seasonality of the business of the Company's
customers. The Company achieved $29.9 million operating income and $13.4 million
net income in the fourth quarter of 1996, compared to $15.4 million operating
income and $6.2 million net income in the first quarter of 1996.
 
     The Company's operating levels increased substantially during 1995 also as
a result of aircraft acquisitions. Block hours rose from 5,812 hours in the
first quarter of 1995 to 10,809 in the fourth quarter, as the average number of
aircraft in the Company's fleet grew from 6.1 aircraft to 9.4 aircraft over the
corresponding period. Total operating revenue increased from $28.9 million in
the first quarter of 1995 to $56.1 million in the fourth quarter, with the
Company's operating income increasing from $3.5 million to $16.2 million and its
net income improving from $0.1 million to $8.4 million over that same period.
For the
                                       16
<PAGE>   17
 
year 1995, total block hours were 33,265 and the average fleet size was 7.7
aircraft. Total operating revenue was $171.3 million, operating income was $42.7
million and net income was $17.8 million.
 
     Operating Expenses. Expenses for flight crew salaries and benefits
increased to $25.0 million in 1996 from $14.6 million in 1995, primarily as a
result of the increase in the Company's fleet of Boeing 747 aircraft from an
average of 7.7 aircraft in 1995 to 14.7 aircraft in 1996, while aircraft block
hours increased from 33,265 to 59,445, or 79%, over such period. On a block hour
basis, this expense declined to $421 per hour for 1996 from $438 per hour for
1995, or approximately 4%, due to increased staffing and scheduling efficiencies
associated with increased operations.
 
     Other flight-related expenses rose to $27.4 million in 1996 from $12.4
million in 1995, or approximately 120%, primarily due to fleet expansion and
higher travel costs associated with operational difficulties related to the
aircraft sub-leased from FedEx. On a per block hour basis, other flight-related
expenses increased from $372 per block hour in 1995 to $461 per block hour in
1996, or approximately 24%.
 
     Maintenance expense increased to $84.3 million in 1996 from $42.6 million
in 1995, or approximately 98%, due to the increase in average fleet size and
certain increased costs associated with introducing the aircraft sub-leased from
FedEx into the Company's fleet and higher ongoing maintenance costs. The
aircraft sub-leased from FedEx are not covered by the Company's maintenance
contracts with KLM and GE described above. On a block hour basis, maintenance
expense increased by 11%, primarily due to parts support requirements associated
with scheduled and unscheduled maintenance events, and due to the maintenance
costs for the aircraft sub-leased from FedEx discussed above.
 
     Aircraft and engine rentals were $27.3 million in 1996 compared to $22.9
million in 1995, representing an increase of 19%. Lease costs in 1996 for the
aircraft sub-leased from FedEx represented $9.7 million of this increase, offset
by a $2.4 million decrease in sub-service rentals in 1996 compared to 1995. In
addition, the lease costs for one aircraft in 1995 exceeded the lease costs in
1996 by $1.6 million, due to the Company's purchase of the aircraft in the
second quarter of 1996. Engine rentals decreased by $1.8 million in 1996 to $1.8
million, due to the purchase of eight spare engines which reduced the Company's
need for leased engines.
 
     Fuel and ground handling costs increased to $10.6 million in 1996 from $5.0
million in 1995, or approximately 110%. This increase was primarily due to an
increase in block hours for scheduled service, charters, ferry and other from
1,070 in 1995 to 2,042 in 1996, or approximately 91%. In addition, the airline
industry experienced a rise in fuel costs over the period.
 
     Depreciation and amortization expense increased to $25.5 million in 1996
from $14.8 million in 1995, reflecting the increase in the number of owned
aircraft in the Company's fleet. On a per block hour basis, this expense
decreased from $445 per block hour in 1995 to $429 per block hour in 1996, or
approximately 4%. The proportion of owned aircraft to leased aircraft was
relatively the same for 1996 as it was for 1995.
 
     Other operating expenses increased to $27.5 million in 1996 from $16.4
million in 1995, or approximately 68%. On a block hour basis, other operating
expenses decreased from $492 per block hour in 1995 to $462 per block hour in
1996, or approximately 6%, reflecting a lower rate of growth in the Company's
overhead as compared to its operational growth.
 
     Other Income (Expense). Interest income increased to $7.1 million for 1996
from $2.0 million in 1995. This increase was primarily due to the investment of
$99.6 million of funds received from the secondary public offering ("SPO") in
May 1996, as well as funds retained from the Company's initial public offering
("IPO") in August 1995. Interest expense increased to $35.6 million in 1996 from
$18.5 million in 1995, resulting from the increase in financed flight equipment
between these periods.
 
     Income Taxes. Pursuant to the provisions of SFAS No. 109, "Accounting for
Income Taxes," the Company has recorded a tax provision based on tax rates in
effect during the period. Accordingly, the Company accrued taxes at the rate of
36.5% in 1996 and 32.0% in 1995. Due to significant capital costs, which are
depreciated at an accelerated rate for tax purposes, a majority of the Company's
tax provision in 1996 and 1995 is deferred.

LIQUIDITY AND CAPITAL RESOURCES
 
     At December 31, 1997, the Company had cash and cash equivalents of
approximately $41.3 million, short-term investments of approximately $111.6
million and working capital of approximately $80.4 million. During 1997, cash
and cash equivalents increased approximately $31.5 million, principally
reflecting cash provided from operations of $87.7 million, proceeds from
equipment financings of $815.8 million and net proceeds from the sale and
purchase of short-term investments of $3.2 million, partially offset by the net
sale and purchase of investments in flight and other equipment of $364.0
million, principal reductions of indebtedness of $494.1 million, debt issuance
costs of $16.6 million and net treasury stock purchases of $0.4 million.
 
     At December 31, 1996, the Company had cash and cash equivalents of
approximately $9.8 million, short-term investments of approximately $114.9
million and working capital of approximately $98.7 million. During 1996, cash
and cash equivalents decreased $87.2 million, principally reflecting investments
in flight and other equipment of $289.7 million, the net purchase of $114.9
million of short-term investments, debt issuance costs of $6.0 million,
principal reductions of indebtedness of $21.6 million and net treasury stock
purchases of $0.5 million, partially offset by cash provided from operations of
$84.4 million, proceeds from equipment financings of $154.8 million, net common
stock issuances of $106.3 million, including the $99.6 million received from the
SPO in the second quarter of 1996.
 
     In May 1996, the Company entered into a $175 million revolving credit
facility (the "Aircraft Acquisition Credit Facility") with Goldman Sachs Credit
Partners L.P. ("Goldman Sachs"), as Syndication Agent, and Bankers Trust Company
("BTCo"), as Administrative Agent. This revolving loan facility provides for the
acquisition and conversion of flight equipment. The Aircraft Acquisition Credit
Facility was subsequently amended and restated in conjunction with certain
refinancings. The Third Amended and Restated Credit Facility provides for a $250
million revolving credit facility as of September 5, 1997 with a two-year
revolving period and a subsequent three-year term loan period in the event that
permanent financing has not been obtained for any flight equipment financed
under the facility. At the time of each borrowing, the Company must select
either a Base Rate Loan (prime rate, plus 1.5% through May 8, 1998, thereafter
plus 2.0%) or a Eurodollar Rate Loan (Eurodollar rate, plus 2.5% through May 8,
1998, thereafter plus 3.0%). The Eurodollar Rate Loan was selected by the
Company for substantially all borrowings in 1996 and 1997. The weighted average
interest rate on borrowings outstanding under the Aircraft Acquisition Credit
Facility was 8.38% at December 31, 1997. Each borrowing is secured by a first
priority security interest in the collateral flight equipment of that borrowing.
Certain tests must be met before each purchase of aircraft and related drawdown
on the facility. To date, the Company has met these tests. If in the future, the
Company cannot meet all the tests because of the difficult sequencing of
aircraft acquisition, aircraft conversion and customer contracts, the Company
believes that other financing sources would be available to the Company or that
it would acquire aircraft using its internal cash or seek a waiver of any
necessary conditions. As of December 31, 1997, the Company had $85.0 million
outstanding under the Aircraft Acquisition Credit Facility. Covenants with
respect to the Aircraft Acquisition Credit Facility require specific levels of
insurance, as well as contain requirements regarding possession, maintenance,
and lease or transfer of the flight equipment. Certain covenants applicable to
the Company include, among other restrictions, limitations on indebtedness,
liens, investments, contingent obligations, restricted junior payments, capital
expenditures and leases. The Company was in compliance with all of its covenants
at December 31, 1997.
 
     In March 1997, the Company refinanced one of its aircraft with Nationsbanc
Leasing Corporation ("Nationsbanc"). This aircraft was previously financed
through the Aircraft Acquisition Credit Facility. As such, this refinancing
increased the availability of funds under the Aircraft Acquisition Credit
Facility by approximately $25 million. The Nationsbanc financing is a seven year
term loan (extendible under certain circumstances to ten years) which provides
for a fixed interest rate of 9.16%. The loan is secured by a first priority
security interest in this aircraft.
 
     In April 1997, the Company purchased the fifth and sixth aircraft from Thai
Airways. These aircraft were placed into service in the third quarter of 1997
subsequent to undergoing modification to cargo configuration
 
                                       18

by Boeing. These aircraft were initially financed under the Aircraft Acquisition
Credit Facility and were subsequently refinanced as part of the AFL II Term Loan
Facility (see below).
 
     In May 1997, the Company acquired from Citicorp Investor Lease, Inc.
("Citicorp") one 747-200 passenger aircraft for a purchase price of $25 million,
including two spare engines. In connection with the purchase of the aircraft
from Citicorp, the Company agreed to assume Citicorp's lessor interest in the
lease of such aircraft to Philippine Airlines ("PAL") for the remainder of the
lease term. This aircraft is financed under the Aircraft Acquisition Credit
Facility. See "-- Recent Developments."
 
     In May 1997, the Company formed a wholly-owned subsidiary, Atlas Freighter
Leasing, Inc. ("AFL"), for the purpose of entering into the $185 million AFL
Term Loan Facility (the "AFL Term Loan Facility") to refinance six Boeing
747-200 aircraft previously financed through Internationale Nederlanden Aviation
Lease B.V. ("ING Bank"). Concurrent with entering into the AFL Term Loan
Facility, the proceeds of the AFL Term Loan Facility were used to repay all
existing principal and interest due under the ING Bank debt. Interest is based
on the Eurodollar rate, plus 2.5% for the first three years and 3.0% thereafter,
and is payable quarterly. The interest rate on borrowings outstanding under the
AFL Term Loan Facility was 8.38% at December 31, 1997. Quarterly scheduled
principal payments of $2.5 million commenced in February 1998 and increase to
$5.7 million in August 1998 with a final payment of $50.0 million in May 2004.
The AFL Term Loan Facility is secured by a first priority interest in the six
subject aircraft and is restrictive with respect to limitations on indebtedness,
liens, investments, contingent obligations, restricted junior payments, capital
expenditures, amendments of material agreements, leases, transactions with
shareholders and affiliates and the conduct of business. AFL was in compliance
with all of its covenants as of December 31, 1997.
 
     In June 1997, the Company entered into the Boeing Purchase Agreement to
purchase 10 new 747-400 freighter aircraft to be powered by GE engines. The
747-400 freighter aircraft are currently scheduled to be delivered as follows:
five in 1998, two in 1999 and three in 2000. Due to production problems at
Boeing, the Company believes that each of the 1998 delivery positions of the
747-400 aircraft may be delayed up to 60 days. While Boeing will compensate the
Company for defined delays in delivery of the 747-400 aircraft, any such delays
may adversely impact the Company's ability to initiate service with prospective
customers in a timely fashion. The Boeing Purchase Agreement also provides the
Company with options to purchase up to 10 additional 747-400 freighter aircraft
for delivery from 1999 through 2002. As a result of the Company being the
largest purchaser of 747-400 freighter aircraft to date, it was able to
negotiate from Boeing and GE a significant discount off the aggregate list price
of $1.7 billion for the 10 747-400 freighter aircraft, four installed engines
per aircraft and five spare engines. In addition, the Company also obtained
certain ancillary products and services at advantageous prices. The Boeing
Purchase Agreement requires that the Company pay Pre-Delivery Deposits to Boeing
prior to the delivery date of each 747-400 freighter aircraft in order to secure
delivery of the 747-400 freighter aircraft and to defray a portion of the
manufacturing costs. The Company expects the maximum total amount of
Pre-Delivery Deposits at any time outstanding will be approximately $155
million, approximately $105.1 million of which was paid as of December 31, 1997.
For the years 1998 and 1999, the Company expects to pay $67.6 million and $42.6
million, respectively, in accordance with the Pre-Delivery Deposits schedule. In
addition, the Boeing Purchase Agreement provides for a deferral of a portion of
the Pre-Delivery Deposits (Deferred Aircraft Obligations) for which the Company
accrues and pays interest quarterly at 6-month LIBOR, plus 2.00%. As of December
31, 1997, there was $163.2 million of Deferred Aircraft Obligations outstanding
and the combined interest rate was 7.97%.
 
     In August 1997, the Company completed the offering of its unsecured 10 3/4%
Senior Notes due 2005 ("Senior Notes"). The proceeds from the offering of the
Senior Notes were used to, among other things, repay short-term indebtedness
incurred by the Company to make pre-delivery deposits to Boeing for the purchase
of 10 new freighter aircraft and for additional pre-delivery deposits as they
become due. Interest on the Senior Notes began to accrue from their date of
original issuance and is payable semi-annually in arrears on February 1 and
August 1 of each year, commencing February 1, 1998, at the rate of 10 3/4% per
annum. The Senior Notes are redeemable, in whole or in part, at the option of
the Company, on or after August 1, 2001, at established redemption prices, plus
accrued interest to the date of redemption. In addition, at any time on or prior
to August 1, 2000, the Company, at its option, may redeem up to 35% of the
aggregate principal amount of the Senior Notes originally issued with the net
cash proceeds of one or more public equity offerings, at a
                                       19
<PAGE>   20
 
redemption price equal to 110.75% of the principal amount thereof plus accrued
interest to the date of redemption; provided that at least 65% of the aggregate
principal amount of the Senior Notes originally issued remains outstanding
immediately after any such redemption. The Senior Notes are general unsecured
obligations of the Company which rank pari passu in right of payment to any
existing and future unsecured senior indebtedness of the Company. The Senior
Notes are effectively subordinated, however, to all secured indebtedness of the
Company and to all indebtedness of the Company's subsidiaries. Covenants with
respect to the Senior Notes contain certain limitations on the ability of the
Company and its subsidiaries to, among other things, incur additional
indebtedness, pay dividends or make certain other restricted payments,
consummate certain asset sales, enter into certain transactions with affiliates,
incur liens, create restrictions on the ability of a subsidiary to pay dividends
or make certain payments, sell or issue preferred stock of subsidiaries to third
parties, merge or consolidate with any other person or sell, assign, transfer,
lease, convey or otherwise dispose of all or substantially all of the assets of
the Company. The Company was in compliance with all of its covenants as of
December 31, 1997.
 
     In September 1997, the Company formed another wholly-owned subsidiary,
Atlas Freighter Leasing II, Inc. ("AFL II") for the purpose of entering into the
$185 million AFL II Term Loan Facility (the "AFL II Term Loan Facility") to
refinance four of the aircraft previously financed under the Aircraft
Acquisition Credit Facility, plus nine spare engines, in order to provide the
Company with greater financial flexibility in anticipation of the financing
requirements for the future acquisition of additional freighter aircraft.
Interest is based on the Eurodollar rate, plus 2.25%, less a pricing reduction,
if any, in effect from time to time, and is payable quarterly. The interest rate
on borrowings outstanding under the AFL II Term Loan Facility was 8.13% at
December 31, 1997. Quarterly scheduled principal payments of $2.5 million
commenced in February 1998 and increase to $5.7 million in August 1998 with a
final payment of $50.0 million in May 2004. The AFL II Term Loan Facility is
secured by a first priority interest in the four subject aircraft, plus nine
spare engines, and is restrictive with respect to limitations on indebtedness,
liens, investments, contingent obligations, restricted junior payments, capital
expenditures, amendments of material agreements, leases, transactions with
shareholders and affiliates and the conduct of business. AFL II was in
compliance with all of its covenants as of December 31, 1997.
 
     In October 1997, Atlas Flightlease, Inc. ("AFI"), a wholly-owned subsidiary
of the Company, secured a 2-year LIBOR based financing with Bankers Trust
Company for approximately 80% of the purchase price of a 1988 Canadair
Challenger passenger aircraft (the "Challenger"). AFI purchased the Challenger
from MAC Flightlease, Inc. ("MAC Flightlease"), an entity wholly-owned by the
wife of the Company's Chairman, President and CEO (see Note 7 to the
Consolidated Financial Statements), in the third quarter of 1997. In December
1997, AFI refinanced the Challenger for approximately 100% of its purchase price
with Nationsbanc under a 5-year loan which was guaranteed by the Company.
Interest is based on the Eurodollar rate, plus 2.35%, and is payable quarterly
with concurrent scheduled payments of principal. The interest rate on borrowings
outstanding under the Nationsbanc debt was 8.26% at December 31, 1997. The loan
is secured by a first priority security interest in the Challenger. Covenants
with respect to this financing require specific levels of insurance, as well as
contain requirements regarding use, maintenance, configuration, liens and
disposition of the Challenger, among other things. AFI was in compliance with
all of its covenants as of December 31, 1997.
 
     Due to the contractual nature of the Company's business, the Company's
management does not consider its operations to be highly working
capital-intensive in nature. Because most of the non-ACMI costs normally
associated with operations are borne by and directly paid for by the Company's
customers, the Company does not incur significant costs in advance of the
receipt of corresponding revenues. Moreover, ACMI costs, which are the
responsibility of the Company, are generally incurred on a regular, periodic
basis ranging from flight hours to months. These costs are largely matched by
revenue receipts, as the Company's contracts require regular payments from its
customers, based upon current flight activity, generally every two to four
weeks. As a result, the Company has not in the past had a requirement for a
working capital facility. The Company is exploring the possibility of entering
into an unsecured line of credit for general working capital purposes.
 
     Under the FAA's Directives issued under its Aging Aircraft program, the
Company is subject to extensive aircraft examinations and may be required to
undertake structural modifications to address the
                                       20
<PAGE>   21
 
problem of corrosion and structural fatigue. In November 1994, Boeing issued
Nacelle Strut Modification Service Bulletins which have been converted into
Directives by the FAA. Twelve of the Company's Boeing 747-200 aircraft will have
to be brought into compliance with such Directives within the next three years
at an estimated cost of approximately $6.0 million. As part of the FAA's overall
aging aircraft program, it has issued Directives requiring certain additional
aircraft modifications to be accomplished prior to the aircraft reaching 20,000
cycles. The average cycle time for the 17 aircraft in service is approximately
12,000 cycles and the average cycles operated per year is approximately 800
cycles. The Company estimates that the modification costs per aircraft will
range between $2 million and $3 million. Between now and the year 2000, only one
aircraft is expected to reach the 20,000 cycle limit and nine additional
aircraft will require modification prior to 2009. The remaining seven aircraft
in service have already undergone such modifications. The two aircraft
undergoing modification to freighter configuration will receive the Nacelle
Strut Modification as part of the freighter conversion. Other Directives have
been issued that require inspections and minor modifications to Boeing 747-200
aircraft. It is possible that additional Directives applicable to the types of
aircraft or engines included in the Company's fleet could be issued in the
future, the cost of which could be substantial. Upon acquisition of an aircraft,
the Company determines whether or not the aircraft is in compliance with
Airworthiness Directives and tries to anticipate all future compliance
requirements. The necessary work to bring the aircraft into compliance is then
scheduled at the time of conversion of the aircraft to freighter configuration,
in order to minimize unscheduled maintenance events.
 
     The Company has initiated a review of its internal information systems for
any Year 2000 transition problems through a company-wide effort, assisted by
Year 2000 experienced consultants, to address internal Year 2000 system issues,
and jointly with industry trade groups, to address issues related to key
business partners which are common to other air carriers. The Company has not
completed the development of the remediation approach for all affected areas. As
a result, the Company cannot estimate what the total cost will be to implement
remediation efforts for all critical operational systems. However, due to the
Company's relatively young systems, the Company's advanced client server and
data base architecture, and the Company's partial reliance on vendor
representations regarding Year 2000 compliant third-party systems, the Company
is confident that such remediation efforts will not be material. The Company
expects to complete the assessment and development stages of this plan by
mid-1998, at which time it expects to be able to make a reasonable cost
estimate. Implementation of all remediation efforts is scheduled to be completed
in early 1999.
 
     The Company has started an ongoing program to review the status of key
supplier Year 2000 compliance efforts. While the Company believes it is taking
all appropriate steps to assure Year 2000 compliance, it is dependent on key
business partner compliance to some extent. The Year 2000 problem is pervasive
and complex, as virtually every computer operation will be affected in some way.
Consequently, no assurance can be given that Year 2000 compliance can be
achieved without costs that might affect future financial results or cause
reported financial information not to be necessarily indicative of future
operating results or future financial condition.
 
     From time to time the Company engages in discussions with third parties
regarding possible acquisitions of aircraft that could expand the Company's
operations. The Company is in discussions with third parties for the possible
acquisition of additional aircraft for delivery in 1998 and beyond.
 
RECENT DEVELOPMENTS
 
     In January and February 1998, pursuant to an early lease termination
agreement negotiated in November 1997, the Company delivered to Boeing for
modification to cargo configuration the aircraft acquired from Marine Midland in
December 1996 and the aircraft acquired from Citicorp in May 1997. These
aircraft are expected to be re-delivered to the Company in the second quarter
and early in the third quarter of 1998, respectively. The financing for the
modification to cargo configuration is secured under the Aircraft Acquisition
Credit Facility.
 
     In February 1998, the Company completed an offering of $538.9 million of
pass-through certificates, also known as enhanced equipment trust certificates
(the "EETCs"). The EETCs are not direct obligations of, or guaranteed by, the
Company and therefore will not be included in the Company's consolidated
financial
 
                                       21
<PAGE>   22
 
statements. The cash proceeds from the transaction were deposited with an escrow
agent and will be used to finance (through either leveraged leases or secured
debt financings) the debt portion of the acquisition cost of five of the 10 new
747-400 freighter aircraft from Boeing scheduled to be delivered to the Company
during the period July 1998 through December 1998. In connection therewith, the
Company intends to seek certain owner participants who will commit lease equity
financing to be used in leveraged leases of such aircraft. If any funds remain
as deposits with the escrow agent for such EETCs at the end of the delivery
period, such funds will be distributed back to the certificateholders. Such
distribution will include a make-whole premium payable by the Company. In
November and December 1997, the Company entered into three Treasury Note hedges,
approximating $300 million of principal, for the purpose of minimizing the risk
associated with the fluctuations in interest rates, which are the basis for the
pricing of the EETCs which were priced in January 1998. The effect of the hedge
resulted in a deferred cost of $6.3 million, which will be amortized over the
expected twenty-year life associated with this financing.
 
     There can be no assurance that the Company will be able to obtain
sufficient financing to fund the purchase of the remaining five 747-400
freighter aircraft, or if such financing is available, that it will be available
on a commercially reasonable basis. If it is unable to do so, the Company could
be required to modify its expansion plans or to incur higher than anticipated
financing costs, which could have a material adverse effect on the Company.
 
     The Company is currently negotiating for the possibility of refinancing two
aircraft in the amount of approximately $86 million, currently financed under
the Aircraft Acquisition Credit Facility. There is no assurance that this
refinancing will be consummated.
 
     The Company believes that cash on hand, the cash flow generated from its
operations and the proceeds from the May 1996 SPO and the August 1997 placement
of the Senior Notes, coupled with availability under the Aircraft Acquisition
Credit Facility and the proceeds of the EETCs, will be sufficient to meet its
normal ongoing liquidity needs for 1998.
 
RECENTLY ISSUED ACCOUNTING STANDARDS
 
     In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards ("SFAS") No. 128 "Earnings per Share,"
effective for financial statements for both interim and annual periods ending
after December 15, 1997. The purpose of SFAS No. 128 is to simplify the
computation of earnings per share ("EPS") and to make the U.S. standard for
computing EPS more compatible with the EPS standards of other countries and with
that of the International Accounting Standards Committee. SFAS No. 128 requires
the dual presentation of basic earnings per share ("basic EPS"), which replaces
primary earnings per share, and diluted earnings per share ("diluted EPS").
Basic EPS is computed by dividing income available to common stockholders by the
weighted-average number of common shares outstanding during the period. Diluted
EPS is computed similar to basic EPS except that the weighted-average number of
common shares outstanding during the period is adjusted for the incremental
shares attributed to outstanding options to purchase common stock.
 
     In June 1997, the Financial Accounting Standards Board issued SFAS No. 130
"Reporting Comprehensive Income," which establishes standards for reporting and
display of comprehensive income and its components in a full set of general
purpose financial statements. The objective of SFAS No. 130 is to report a
measure of all changes in equity of an enterprise that result from transactions
and other economic events of the period other than transactions with owners.
Comprehensive income includes net income plus other comprehensive income (other
revenues, expenses, gains, and losses that under generally accepted accounting
principles bypass net income). The Company does not expect other comprehensive
income to be material. The effective date for the application of SFAS No. 130
for both interim and annual periods is for fiscal years beginning after December
15, 1997 with earlier application permitted.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Atlas Air, Inc.:
 
     We have audited the accompanying consolidated balance sheets of Atlas Air,
Inc. (a Delaware corporation) and subsidiaries as of December 31, 1997 and 1996,
and the related consolidated statements of operations, stockholders' equity
(deficit) and cash flows for each of the three years in the period ended
December 31, 1997. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Atlas Air, Inc. and subsidiaries as of December 31, 1997 and 1996, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1997, in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization
 
     Atlas Air, Inc. (the "Company") provides airport to airport cargo services
throughout the world to major international airlines pursuant to contractual
arrangements with its customers in which the Company provides the aircraft,
crew, maintenance and insurance ("ACMI"), referred to as "contract services."
The Company also provides charter services and scheduled services on an ad hoc
basis. The principal markets served by the Company are Asia and the Pacific Rim
from the United States and Europe, and between South America and the United
States.
 
  Principles of Consolidation
 
     The accompanying consolidated financial statements include the accounts of
the Company and its wholly-owned subsidiaries. All material intercompany
balances and transactions have been eliminated in consolidation.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Property and Equipment
 
     Owned aircraft are stated at cost. Expenditures for major additions,
improvements, flight equipment modifications and certain overhaul and
maintenance costs are capitalized. A significant portion of scheduled and
unscheduled maintenance is contracted with two maintenance providers under
long-term agreements pursuant to which monthly reserve payments are made to the
providers based on flight-hours and such amounts are charged to expense
currently. Other maintenance and repairs are charged to expense as incurred,
except for significant engine overhaul maintenance which is capitalized and
charged to expense on a flight-hour basis and D checks which are capitalized and
amortized over the corresponding life. Owned aircraft are depreciated over their
estimated useful lives of 20 years, using the straight-line method and estimated
salvage values of 10% of cost. The cost and accumulated depreciation of property
and equipment disposed of are removed from the related accounts and any gain or
loss is reflected in the results of operations. Substantially all property and
equipment is specifically pledged as collateral for indebtedness of the Company.
Whenever events or changes in circumstances indicate that the carrying amount of
an asset may not be recoverable, management evaluates the recorded asset
balances, net of accumulated depreciation, for impairment based on the
undiscounted cash flows associated with the asset. Management believes that
there have been no events or changes in circumstances which would require review
of such recoverability.
 
  Capitalized Interest
 
     Interest attributable to funds used to finance the acquisition and
modification of aircraft is capitalized as an additional cost of the related
aircraft. Interest is capitalized at the Company's weighted average interest
rate on long-term debt, or where applicable, the interest rate related to
specific borrowings. Capitalization of interest ceases when the aircraft is
placed in service. Capitalized interest was $16,115,000, $5,347,000, and
$3,573,000 for the years ended December 31, 1997, 1996 and 1995, respectively.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Deferred Costs
 
     Costs associated with the issuance of debt are capitalized and amortized
over the life of the respective debt obligation, using the effective interest
method for amortization. In May 1997, $3,647,000 of unamortized deferred loan
costs was charged against the extraordinary gain recognized upon early
extinguishment of certain debt (see Note 3). Amortization of debt issuance costs
was $3,620,000, $2,278,000 and $546,000 for the years ended December 31, 1997,
1996 and 1995, respectively.
 
 Cash Equivalents
 
     All highly liquid investments with an original maturity of three months or
less are considered to be cash equivalents, except certain investments in debt
securities which are classified as short-term investments.
 
  Short-Term Investments
 
     All investments in debt securities, other than money market funds, with a
current maturity of less than one year, are considered to be short-term
investments (see Note 2).
 
  Earnings per Share
 
     In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards ("SFAS") No. 128 "Earnings per Share,"
effective for financial statements for both interim and annual periods ending
after December 15, 1997. SFAS No. 128 requires the dual presentation of basic
earnings per share ("basic EPS"), which replaces primary earnings per share, and
diluted earnings per share ("diluted EPS"). Basic EPS is computed by dividing
income available to common stockholders by the weighted-average number of common
shares outstanding during the period. Diluted EPS is computed similar to basic
EPS except that the weighted-average number of common shares outstanding during
the period is adjusted for the incremental shares attributed to outstanding
options to purchase common stock. Options to acquire 405,000, 399,000 and
294,720 shares in 1997, 1996 and 1995, respectively, were not included in the
computation of diluted EPS because the option price was greater than the average
market price of the Company's common stock.
 
  Income Taxes
 
     The Company provides for income taxes using the asset and liability method
prescribed by SFAS No. 109, "Accounting for Income Taxes." Under this method
deferred income taxes are recognized for the tax consequences of temporary
differences by applying enacted statutory tax rates applicable to future years
to differences between the financial statement carrying amounts and the tax
bases of existing assets and liabilities. The effect on deferred taxes of a
change in tax laws or tax rates is recognized in income in the period that
includes the enactment date.
 
  Fair Value of Financial Instruments
 
     The Company's financial instruments consist of cash, certificates of
deposit, short-term investments, short-term trade receivables and payables,
long-term debt and deferred aircraft obligations. The carrying values of cash,
certificates of deposit, and short-term trade receivables and payables
approximate fair value. The fair value of long-term debt is estimated based on
current rates available for similar debt with similar maturities and security
(see Note 3). The fair value of deferred aircraft obligations is based upon the
fair value of the purchase contracts associated with the obligations.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Hedges
 
     The Company may from time to time enter into swaps to reduce exposure to
interest rate fluctuations in connection with certain debt. The cash flows of
the swaps mirror those of the underlying exposures. The premiums on the swaps,
as measured at inception, are amortized over their respective lives as
components of interest expense. Any gains or losses realized upon the early
termination of these swaps are deferred and recognized in income over the
remaining life of the underlying exposure.
 
  Significant Customers and Concentration of Credit Risk
 
     For the year ended December 31, 1997, China Airlines Ltd. ("China
Airlines"), Fast Air Carrier, S.A. ("Fast Air") and Lufthansa Cargo AG
("Lufthansa") accounted for approximately 34%, 11% and 8%, of the Company's
total revenues, respectively. For the year ended December 31, 1996, China
Airlines, KLM Royal Dutch Airlines ("KLM") and Lufthansa accounted for
approximately 34%, 12% and 11%, of the Company's total revenues, respectively.
For the year ended December 31, 1995, China Airlines, KLM and Varig Brazilian
Airlines ("Varig") accounted for approximately 60%, 19% and 11% of the Company's
total revenue, respectively. Accounts receivable from these principal customers
were $18,963,000 and $18,344,000 in the aggregate at December 31, 1997 and 1996,
respectively. The Company is in dispute with one of its customers with respect
to the validity of certain charges for materials and labor that the customer has
invoiced to the Company, and with respect to certain ACMI billings.
 
  Reclassifications
 
     Certain prior year amounts have been reclassified to conform to current
year presentation.
 
  Supplemental Cash Flow Information
 
     The aggregate interest payments made by the Company, net of amounts
capitalized, were $55,097,000, $30,744,000 and $15,563,000 for the years ended
December 31, 1997, 1996 and 1995, respectively. Prior to December 1995, the
required monthly payment under the ING Bank loan agreement was less than the
accrued interest, thus causing $1,258,000 of accrued interest in 1995 to be
financed by the lender as an increase in the principal balance (see Note 3).
 
     The Company made federal and state income tax payments of approximately
$7,959,000, $750,000 and $399,000 in the years ended December 31, 1997, 1996 and
1995, respectively.
 
  Reporting Comprehensive Income
 
     In June 1997, the Financial Accounting Standards Board issued SFAS No. 130
"Reporting Comprehensive Income," which establishes standards for reporting and
display of comprehensive income and its components in a full set of general
purpose financial statements. The objective of SFAS No. 130 is to report a
measure of all changes in equity of an enterprise that result from transactions
and other economic events of the period other than transactions with owners.
Comprehensive income includes net income plus other comprehensive income (other
revenues, expenses, gains, and losses that under generally accepted accounting
principles bypass net income). The Company does not expect other comprehensive
income to be material. The effective date for the application of SFAS No. 130
for both interim and annual periods is for fiscal years beginning after December
15, 1997 with earlier application permitted.
 
2. SHORT-TERM INVESTMENTS
 
     Proceeds from the secondary public offering of the Company's common stock
("SPO") in May 1996, plus additional funds, were invested in various
held-to-maturity securities, as defined in SFAS No. 115, "Accounting for Certain
Investments in Debt and Equity Securities," which requires investments in debt
                                       F-9

  ING Bank Debt
 
     In December 1994, the Company renegotiated its loan agreement with ING
Bank. Pursuant to the new loan agreement, ING Bank agreed to provide up to $231
million of financing to the Company for the purpose of refinancing its existing
loan, financing additional aircraft and the associated costs of converting those
aircraft to freighter configuration, among other things. Subsequently, ING Bank
increased the size of its commitment under the new loan agreement to $232.9
million.
 
     For all but $30,000,000 of the total indebtedness to ING Bank (which amount
was financed at a fixed interest rate of 11.53% through September 1995, at which
time the interest rate was converted to one-month LIBOR ("London Interbank
Offered Rate") plus 2.65%), the loan agreement accrued interest at one-month
LIBOR plus 2.65%. Certain debt covenants under the ING Bank debt precluded one
of the Company's

subsidiaries from declaring dividends, redeeming its own stock for value, or
returning any capital to its stockholders.
 
     In May 1997, the Company used proceeds from the AFL Term Loan Facility (see
below) and approximately $7.6 million in cash to extinguish its ING Bank debt.
The Company recognized an extraordinary gain of $16.7 million (net of taxes of
$9.6 million) as a result of such extinguishment.
 
  Lufthansa Debt
 
     In the first quarter of 1995, the Company purchased two aircraft in
passenger configuration from Lufthansa, which financed approximately $12.5
million of the purchase price of each aircraft, for which the Company accrued
interest at an annual rate of 8.8%. In May 1997, the Company paid $6.3 million
to satisfy the remaining Lufthansa debt balance in conjunction with the
refinancing of these aircraft under the AFL Term Loan Facility (see below).
 
  Equipment Notes
 
     In November 1995, the Company sold $100 million of 12 1/4% Pass Through
Certificates. Each 12 1/4% Pass Through Certificate due 2002 (each a
"Certificate") represents a fractional undivided interest in the Atlas Air Pass
Through Trust (the "Trust") formed pursuant to a pass through trust agreement
between the Company and First Fidelity Bank, N.A., as trustee under the Trust.
The property of the Trust consists of 12  1/4% Senior Secured Notes due 2002
(the "Equipment Notes") issued by the Company to finance, together with funds
from the Company, the acquisition and conversion cost of three Boeing 747
aircraft (the "Collateral Aircraft") that were acquired by the Company in the
fourth quarter of 1995 and converted to freighter configuration in the first
quarter of 1996. The Company issued the related Equipment Notes during the
fourth quarter of 1995 and the first quarter of 1996 at or prior to the time
pre-delivery deposits and final purchase price payments were required to be made
with respect to the Collateral Aircraft.
 
     Interest on the Equipment Notes is passed through to the Certificateholders
on June 1 and December 1 of each year, at a rate per annum of 12 1/4%. The
Equipment Notes are redeemable at the option of the Company, in whole or in
part, at any time on or after December 1, 1998 at redemption prices ranging from
108% in 1998 to 100% in 2001 and thereafter, together with accrued and unpaid
interest, if any, to the date of redemption. The Company is required to provide
for the retirement of one-third of the aggregate principal amount of the
Equipment Notes on December 1 in each of 2000 and 2001 through the operation of
a sinking fund at a redemption price of 100% of the principal amount thereof,
together with accrued interest thereon to the redemption date.
 
     Covenants with respect to the Collateral Aircraft require specific levels
of insurance, as well as contain requirements regarding possession, maintenance,
lease or transfer of the aircraft. Certain covenants applicable to the Company
include, among other restrictions, limitations on indebtedness, restricted
payments and restriction on certain asset sales. The Company was in compliance
with all of its covenants as of December 31, 1997.
 
  Finova Debt
 
     The Company obtained financing from Finova Capital Corporation for
approximately 80% of the total acquisition and conversion cost of the first of
six aircraft purchased from Thai Airways International Public Company Limited
(the "Thai Aircraft") (see below), or $32.8 million. The loan accrues interest
at 10.13% and matures on October 1, 2003. The loan is secured by a first
priority security interest in the first Thai Aircraft.

  Aircraft Acquisition Credit Facility
 
     In May 1996, the Company entered into a $175 million revolving credit
facility (the "Aircraft Acquisition Credit Facility") with Goldman Sachs Credit
Partners L.P. ("Goldman Sachs"), as Syndication Agent, and Bankers Trust Company
("BTCo"), as Administrative Agent. This revolving loan facility provides for the
acquisition and conversion of flight equipment. The Aircraft Acquisition Credit
Facility was subsequently amended and restated in conjunction with certain
refinancings. The Third Amended and Restated Credit Facility provides for a $250
million revolving credit facility as of September 5, 1997 with a two-year
revolving period and a subsequent three-year term loan period in the event that
permanent financing has not been obtained for any flight equipment financed
under the facility. At the time of each borrowing, the Company must select
either a Base Rate Loan (prime rate, plus 1.5% through May 8, 1998, thereafter
plus 2.0%) or a Eurodollar Rate Loan (Eurodollar rate, plus 2.5% through May 8,
1998, thereafter plus 3.0%). The Eurodollar Rate Loan was selected by the
Company for substantially all borrowings in 1996 and 1997. The weighted average
interest rate on borrowings outstanding under the Aircraft Acquisition Credit
Facility was 8.38% at December 31, 1997. Each borrowing is secured by a first
priority security interest in the collateral flight equipment of that borrowing.
Certain tests must be met before each purchase of aircraft and related drawdown
on the facility. To date, the Company has met these tests. If in the future, the
Company cannot meet all the tests because of the difficult sequencing of
aircraft acquisition, aircraft conversion and customer contracts, the Company
believes that other financing sources would be available to the Company or that
it would acquire aircraft using its internal cash or seek a waiver of any
necessary conditions. As of December 31, 1997, the Company had $85.0 million
outstanding under the Aircraft Acquisition Credit Facility.
 
     Covenants with respect to the Aircraft Acquisition Credit Facility require
specific levels of insurance, as well as contain requirements regarding
possession, maintenance, and lease or transfer of the flight equipment. Certain
covenants applicable to the Company include, among other restrictions,
limitations on indebtedness, liens, investments, contingent obligations,
restricted junior payments, capital expenditures and leases. The Company was in
compliance with all of its covenants at December 31, 1997.
 
  Nationsbanc
 
     In March 1997, the Company refinanced one of its aircraft with Nationsbanc
Leasing Corporation ("Nationsbanc"). This aircraft was previously financed
through the Aircraft Acquisition Credit Facility. As such, this refinancing
increased the availability of funds under the Aircraft Acquisition Credit
Facility by approximately $25 million. The Nationsbanc financing is a seven year
term loan (extendible under certain circumstances to ten years) which provides
for a fixed interest rate of 9.16%. The loan is secured by a first priority
security interest in this aircraft.
 
  AFL Term Loan Facility
 
     In May 1997, the Company formed a wholly-owned subsidiary, Atlas Freighter
Leasing, Inc. ("AFL"), for the purpose of entering into the $185 million AFL
Term Loan Facility (the "AFL Term Loan Facility") to refinance six Boeing
747-200 aircraft previously financed through the ING Bank debt (see above).
Concurrent with entering into the AFL Term Loan Facility, the proceeds of the
AFL Term Loan Facility were used to repay all existing principal and interest
due under the ING Bank debt. Interest is based on the Eurodollar rate, plus 2.5%
for the first three years and 3.0% thereafter, and is payable quarterly. The
interest rate on borrowings outstanding under the AFL Term Loan Facility was
8.38% at December 31, 1997. Quarterly scheduled principal payments of $2.5
million commenced in February 1998 and increase to $5.7 million in August 1998
with a final payment of $50.0 million in May 2004. The AFL Term Loan Facility is
secured by a first priority interest in the six subject aircraft and is
restrictive with respect to limitations on indebtedness, liens, investments,
contingent obligations, restricted junior payments, capital expenditures,

amendments of material agreements, leases, transactions with shareholders and
affiliates and the conduct of business. The Company was in compliance with all
of its covenants as of December 31, 1997.
 
  AFL II Term Loan Facility
 
     In September 1997, the Company formed another wholly-owned subsidiary,
Atlas Freighter Leasing II, Inc. ("AFL II") for the purpose of entering into the
$185 million AFL II Term Loan Facility (the "AFL II Term Loan Facility") to
refinance four of the aircraft previously financed under the Aircraft
Acquisition Credit Facility, plus nine spare engines, in order to provide the
Company with greater financial flexibility in anticipation of the financing
requirements for the future acquisition of additional aircraft. Interest is
based on the Eurodollar rate, plus 2.25%, less a pricing reduction, if any, in
effect from time to time and is payable quarterly. The interest rate on
borrowings outstanding under the AFL II Term Loan Facility was 8.13% at December
31, 1997. Quarterly scheduled principal payments of $2.5 million commenced in
February 1998 and increase to $5.7 million in August 1998 with a final payment
of $50.0 million in May 2004. The AFL II Term Loan Facility is secured by a
first priority interest in the four subject aircraft, plus nine spare engines,
and is restrictive with respect to limitations on indebtedness, liens,
investments, contingent obligations, restricted junior payments, capital
expenditures, amendments of material agreements, leases, transactions with
shareholders and affiliates and the conduct of business. The Company was in
compliance with all of its covenants as of December 31, 1997.
 
  Senior Notes
 
     In August 1997, the Company completed the offering of its unsecured 10 3/4%
Senior Notes due 2005 ("Senior Notes"). The proceeds from the offering of the
Senior Notes were used to, among other things, repay short-term indebtedness
incurred by the Company to make pre-delivery deposits to The Boeing Company
("Boeing") for the purchase of 10 new freighter aircraft (see Note 6) and for
additional pre-delivery deposits as they become due.
 
     Interest on the Senior Notes began to accrue from their date of original
issuance and is payable semi-annually in arrears on February 1 and August 1 of
each year, at the rate of 10 3/4% per annum. The Senior Notes are redeemable, in
whole or in part, at the option of the Company, on or after August 1, 2001, at
105.375%, 102.688% and 100.000% for the years 2001, 2002 and 2003 and
thereafter, respectively, plus accrued interest to the date of redemption. In
addition, at any time on or prior to August 1, 2000, the Company, at its option,
may redeem up to 35% of the aggregate principal amount of the Senior Notes
originally issued with the net cash proceeds of one or more public equity
offerings, at a redemption price equal to 110.75% of the principal amount
thereof plus accrued interest to the date of redemption; provided that at least
65% of the aggregate principal amount of the Senior Notes originally issued
remains outstanding immediately after any such redemption.
 
     The Senior Notes are general unsecured obligations of the Company which
rank pari passu in right of payment to any existing and future unsecured senior
indebtedness of the Company. The Senior Notes are effectively subordinated,
however, to all secured indebtedness of the Company and to all indebtedness of
the Company's subsidiaries.
 
     Covenants with respect to the Senior Notes contain certain limitations on
the ability of the Company and its subsidiaries to, among other things, incur
additional indebtedness, pay dividends or make certain other restricted
payments, consummate certain asset sales, enter into certain transactions with
affiliates, incur liens, create restrictions on the ability of a subsidiary to
pay dividends or make certain payments, sell or issue preferred stock of
subsidiaries to third parties, merge or consolidate with any other person or
sell, assign, transfer, lease, convey or otherwise dispose of all or
substantially all of the assets of the Company. The Company was in compliance
with all of its covenants as of December 31, 1997.

  Nationsbanc - AFI Debt
 
     In October 1997, Atlas Flightlease, Inc. ("AFI"), a wholly-owned subsidiary
of the Company, secured a 2-year LIBOR based financing with Bankers Trust
Company for approximately 80% of the purchase price of a 1988 Canadair
Challenger passenger aircraft (the "Challenger"). AFI purchased the Challenger
from MAC Flightlease, Inc. ("MAC Flightlease"), an entity wholly-owned by the
wife of the Company's Chairman, President and CEO (see Note 7), in the third
quarter of 1997. In December 1997, AFI refinanced the Challenger for
approximately 100% of its purchase price with Nationsbanc under a 5-year loan
which was guaranteed by the Company. Interest is based on the Eurodollar rate,
plus 2.35%, and is payable quarterly with concurrent scheduled payments of
principal. The interest rate on borrowings outstanding under the Nationsbanc
debt was 8.26% at December 31, 1997. The loan is secured by a first priority
security interest in the Challenger. Covenants with respect to this financing
require specific levels of insurance, as well as contain requirements regarding
use, maintenance, configuration, liens and disposition of the Challenger, among
other things. AFI was in compliance with all of its covenants as of December 31,
1997.
 
  Hedges
 
     In September 1997, the Company entered into an interest rate swap with BTCo
for the purpose of hedging its floating rate debt. The notional amount of the
interest rate swap is $210 million, decreasing over a term of eight years. The
Company pays a fixed interest rate of 5.72%, increasing .25% annually, and
receives a floating interest rate based on 3-month LIBOR, whereby the net
interest settles quarterly. The 3-month LIBOR rate for the quarterly interest
period which included December 31, 1997 was 5.88%.
 
  Fair Value of Long-Term Debt
 
     Based on current rates available for similar debt with similar maturities
and security, the fair values of the debt in the above table at December 31,
1997, are estimated to be their carrying values. The Equipment Notes and the
Senior Notes are publicly traded. Based on published trading prices at December
31, 1997, the fair values of the Equipment Notes and the Senior Notes are
estimated to be $111.3 million and $105.6 million, respectively.

4. DEFERRED AIRCRAFT OBLIGATIONS
 
     In June 1997, the Company entered into an agreement with Boeing to purchase
10 new 747-400 freighter aircraft (the "Boeing Purchase Agreement") (see Note
6). The Boeing Purchase Agreement requires the Company to pay "Pre-Delivery
Deposits" in order to secure delivery of the 747-400 freighter aircraft and to
defray a portion of the manufacturing costs. In addition, the Boeing Purchase
Agreement provides for a deferral of a portion of the Pre-Delivery Deposits
(Deferred Aircraft Obligations) for which the Company accrues and pays interest
quarterly at 6-month LIBOR, plus 2.00%. As of December 31, 1997, there was
$163.2 million of Deferred Aircraft Obligations outstanding and the combined
interest rate was 7.97%. The Company will settle its Deferred Aircraft
Obligations upon delivery of each of the 10 aircraft, which are scheduled for
delivery as follows: five in 1998, two in 1999 and three in 2000. Financing for
the first five aircraft has been secured through the EETCs (see Note 16). In
addition, the Company may arrange for tax-oriented long-term leases on some or
all of these aircraft.
 
5. INCOME TAXES
 
     The Company had net operating loss carryforwards of approximately
$122,692,000 as of December 31, 1997 which expire between 2008 and 2017. The
Company has generated approximately $8,665,000 of alternative minimum tax credit
carryforwards which are available in subsequent years to reduce its regular tax
liability subject to statutory limitations. All tax years of the Company that
are statutorily open are subject to examination by the Internal Revenue Service
("IRS"), as well as state and local tax authorities. Currently, the fiscal year
ended March 31, 1994, the short year ended December 31, 1994 and the calendar
year ended December 31, 1995 are under examination by the IRS. The Company
believes that it has adequately provided for all income tax liabilities and that
final resolution of any IRS examination will not have a material effect on its
financial position or results of operations.
 
     The provision for income taxes consisted of the following (in thousands):

Thereafter (one Boeing 747-200 aircraft)....................   32,625
</TABLE>
 
     The above commitments do not include the potential lease financing (if any)
of Boeing 747-400 freighter aircraft scheduled for delivery during 1998, 1999
and 2000. In addition to the above commitments, the Company leases engines under
short-term lease agreements on an as needed basis.
 
     Aircraft and engine rentals, including short-term rentals, were
$31,644,000, $27,341,000 and $22,902,000 for the years ended December 31, 1997,
1996 and 1995, respectively.
 
  Boeing Purchase Agreement
 
     In June 1997, the Company entered into the Boeing Purchase Agreement to
purchase 10 new 747-400 freighter aircraft to be powered by GE engines. The
747-400 freighter aircraft are currently scheduled to be delivered as follows:
five in 1998, two in 1999 and three in 2000. Due to production problems at
Boeing, the Company believes that each of the 1998 delivery positions of the
747-400 aircraft may be delayed up to 60 days. While Boeing will compensate the
Company for defined delays in delivery of the 747-400 aircraft, any such delays
may adversely impact the Company's ability to initiate service with prospective
customers in a timely fashion. The Boeing Purchase Agreement also provides the
Company with options to purchase up to 10 additional 747-400 freighter aircraft
for delivery from 1999 through 2002. As a result of the Company being the
largest purchaser of 747-400 freighter aircraft to date, it was able to
negotiate from Boeing and GE a significant discount off the aggregate list price
of $1.7 billion for the 10 747-400 freighter aircraft, four installed engines
per aircraft and five spare engines. In addition, the Company also obtained
certain ancillary

products and services at advantageous prices. The Boeing Purchase Agreement
requires that the Company pay Pre-Delivery Deposits to Boeing prior to the
delivery date of each 747-400 freighter aircraft in order to secure delivery of
the 747-400 freighter aircraft and to defray a portion of the manufacturing
costs. The Company expects the maximum total amount of Pre-Delivery Deposits at
any time outstanding will be approximately $155 million, approximately $105.1
million of which was paid as of December 31, 1997. For the years 1998 and 1999,
the Company expects to pay $67.6 million and $42.6 million, respectively, in
accordance with the Pre-Delivery Deposits schedule. In addition, the Boeing
Purchase Agreement provides for a deferral of a portion of the Pre-Delivery
Deposits (Deferred Aircraft Obligations -- see Note 4) for which the Company
accrues and pays interest quarterly at 6-month LIBOR, plus 2.00%. As of December
31, 1997, there was $163.2 million of Deferred Aircraft Obligations outstanding
and the combined interest rate was 7.97%.
 
  Cargo Modification
 
     In December 1997, the Company supplemented its modification contract with
Boeing to provide for the cargo configuration of two aircraft (acquired in
December 1996 and May 1997) under lease to Philippines Airlines Limited ("PAL"),
which were utilized in passenger configuration by PAL during 1997 and in early
1998. The initial deposit for such modification is recorded in Flight Equipment
in the December 31, 1997 balance sheet. The remaining commitments to Boeing and
other vendors as of December 31, 1997 for both of these aircraft totaled
approximately $20.2 million. These commitments are expected to be paid during
the first three quarters of 1998.
 
  Maintenance Agreements
 
     In January 1995, the Company entered into a maintenance agreement with one
of its principal customers. This agreement includes a provision which requires
the Company to remit a fixed amount per flight hour each month to the customer,
subject to a 3.5% annual escalation factor for the first five years, for which
the customer will perform most regular maintenance on a substantial portion of
the aircraft in the Company's fleet. The agreement extends for a period of ten
years. Pursuant to its maintenance agreement, engines may be upgraded when
inducted into the maintenance pool in order to improve engine reliability and to
lower Company operating costs. When such costs are incurred and identified, they
are capitalized and amortized over the remaining life of each applicable engine.
As of December 31, 1997, the Company had paid the customer $7.5 million for such
costs. The Company expects to incur approximately an additional $2 million to $3
million for such upgrades over the term of the contract.
 
     The Company has an agreement, subject to acceptable rates, terms and
conditions, with Linee Aeree Italiane S.p.A. ("Alitalia") to utilize, or find
other parties to utilize, an amount of Alitalia's maintenance services with an
aggregate cost of $25 million over a five-year period ending in June 2000.
 
     In June 1996, the Company entered into a ten year engine maintenance
agreement with GE for the engine maintenance of up to 15 aircraft powered by
CF6-50E2 engines at a fixed rate per flight hour, subject to an annual formula
increase. The agreement commenced in the third quarter of 1996 with the
acceptance of engines associated with aircraft acquired in the third and fourth
quarters of 1996. Pursuant to its maintenance agreement and upon the first time
shop visit, the Company is invoiced for certain one-time charges, which the
Company capitalizes and amortizes over the lesser of the remaining life of the
asset or the remaining life of the maintenance agreement. As of December 31,
1997, the Company had been invoiced for and paid $4.9 million of such charges.
Effective in the year 2000, the Company will have an option to add not less than
40 engines to the program.
 
  Office and Warehouse
 
     In 1995, the Company entered into an operating lease for office space
expiring in the year 2000, with two five year renewal provisions. In addition,
the Company leases warehouse space for which the initial lease term
                                      F-17

expires at the end of August 1999, and provides for two one-year renewal option
periods. Future minimum rental commitments by year are as follows for the years
ending December 31: 1998 -- $728,000; 1999 -- $708,000; 2000 -- $277,000. Rental
expense, including short-term rentals, was $905,000, $615,000 and $579,000 for
the years ended December 31, 1997, 1996 and 1995, respectively.
 
  Employment Agreements
 
     The Company has entered into employment agreements with certain key
employees. Such employment agreements provide for, among other things, base
annual salary, certain bonuses, the grant of options to purchase common stock of
the Company under the 1995 Stock Option Plan (see Note 14), and in certain
circumstances relocation and severance benefits.
 
  FAA Airworthiness Directives
 
     Under the FAA's Directives issued under its "Aging Aircraft" program, the
Company is subject to extensive aircraft examinations and may be required to
undertake structural modifications to address the problem of corrosion and
structural fatigue. In November 1994, Boeing issued Nacelle Strut Modification
Service Bulletins which have been converted into Directives by the FAA. Twelve
of the Company's Boeing 747-200 aircraft will have to be brought into compliance
with such Directives within the next three years at an estimated cost of
approximately $6.0 million. As part of the FAA's overall aging aircraft program,
it has issued Directives requiring certain additional aircraft modifications to
be accomplished prior to the aircraft reaching 20,000 cycles. The average cycle
time for the 17 aircraft in service is approximately 12,000 cycles and the
average cycles operated per year is approximately 800 cycles. The Company
estimates that the modification costs per aircraft will range between $2 million
and $3 million. Between now and the year 2000, only one aircraft is expected to
reach the 20,000 cycle limit and nine additional aircraft will require
modification prior to 2009. The remaining seven aircraft in service have already
undergone such modifications. The two aircraft undergoing modification to
freighter configuration will receive the Nacelle Strut Modification as part of
the freighter conversion. Other Directives have been issued that require
inspections and minor modifications to Boeing 747-200 aircraft. It is possible
that additional Directives applicable to the types of aircraft or engines
included in the Company's fleet could be issued in the future, the cost of which
could be substantial.
 
     Upon acquisition of an aircraft, the Company determines whether or not the
aircraft is in compliance with Airworthiness Directives and tries to anticipate
all future compliance requirements. The necessary work to bring the aircraft
into compliance is then scheduled at the time of conversion of the aircraft to
freighter configuration, in order to minimize unscheduled maintenance events.
 
  Legal Proceedings
 
     On February 24, 1997, the Company filed a complaint for declaratory
judgment in the Colorado District Court, Jefferson County against Israel
Aircraft Industries Ltd. ("IAI") for mechanical problems the Company experienced
with respect to an aircraft the Company sub-leased from IAI. The Company is
seeking approximately $4 million in damages against IAI to be offset by the
amount, if any, the Company owes IAI pursuant to the sub-lease. IAI had the case
removed to the U.S. District Court, District of Colorado on April 21, 1997 and
has filed counterclaims alleging damages of approximately $9 million based on
claims arising from the sub-lease. The Company intends to vigorously defend
against all of IAI's claims.
 
     In March 1997, Air Support International, Inc. ("ASI") filed a complaint
against the Company in the U.S. District Court, Eastern District of New York
alleging actual and punitive damages of approximately $13.5 million arising from
the Company's refusal to pay commissions which ASI claims it is owed for
allegedly arranging certain ACMI Contracts. The Company intends to vigorously
defend against all of ASI's claims.

     While the Company is from time to time involved in litigation in the
ordinary course of its business, there are no other material legal proceedings
pending against the Company or to which any of its property is subject.
 
7. RELATED PARTY TRANSACTIONS
 
     In June 1995, the Company extended a non-interest bearing loan to an
officer of the Company in the amount of $125,000 in connection with such
officer's relocation to Colorado, which the Company forgave in July 1995.
 
     In August and September 1995, the Company extended demand loans to three
senior vice presidents of the Company in the aggregate amount of $550,000,
bearing interest at an annual rate of 7.50%. Two of the loans plus interest were
paid in full in April and May 1996, and the third loan plus interest was paid in
full in December 1997. A loan of up to $750,000, bearing interest at 5.87%, was
extended in June 1996 to one officer for the purpose of constructing a
residence. As of December 31, 1997 the outstanding balance of officer demand
loans was $735,000.
 
     In November 1995, the Company began renting a Cessna Citation SP, on an as
needed basis, from MAC Flightlease for the purpose of corporate business travel.
MAC Flightlease is wholly-owned by the wife of the Company's Chairman, President
and CEO. The Company paid $265,000 in 1996 and $52,000 in 1995 for such travel,
at rates which are considered by the Company to be at fair market value.
 
     In October 1997, AFI purchased from MAC Flightlease the Challenger for
corporate business travel. Initially, AFI secured a 2-year LIBOR based financing
with BTCo for approximately 80% of the purchase price of the Challenger. In
December 1997, AFI refinanced the Challenger for approximately 100% of its
purchase price with Nationsbanc under a 5-year LIBOR based loan which was
guaranteed by the Company. The Company paid $15.3 million for the Challenger,
which is considered by the Company to be at fair market value.

10. WRITE-OFF OF CAPITAL INVESTMENT AND OTHER
 
     In conjunction with the June 1997 agreement with Boeing to purchase 10 new
747-400 freighter aircraft, the Company reassessed the economic viability of
renewing on a longer-term basis its sub-leases with Federal Express Corporation
("FedEx") for five 747-200 freighter aircraft. Based on the results of this
assessment in the second quarter of 1997, the Company decided to schedule the
return of these aircraft in the first quarter of 1998. The Company wrote-off its
remaining investment in the five FedEx aircraft and established certain other
reserves.
 
     The impact of the various largely non-recurring charges was $27.1 million,
or $17.2 million on an after-tax basis, which comprised write-offs of various
leasehold improvements associated with the Company's sub-leases with FedEx of
the five 747-200 aircraft and reserves for costs necessary to return the
aircraft upon the termination of the sub-leases. In addition, the Company
established reserves primarily related to certain customers and vendors for
out-of-period items for which the Company is currently in negotiations. In
addition, the reserves include estimates for litigation costs and other costs
not expected to re-occur.
 
11. SAVINGS AND RETIREMENT PLAN
 
     The Company implemented a 401(k) Retirement Plan (the "Plan") in June 1994,
under which eligible employees may contribute up to 15% of their total pay. The
Plan covers substantially all employees. The Company did not make contributions
to the Plan in 1995. Effective May 1, 1996, the Plan was amended to provide for
Company contributions equal to 50% of the first 10% of contributions made by
employees, for which the Company incurred an expense of $1,255,000 and $559,000
for the years ended December 31, 1997 and 1996, respectively.
 
12. BUSINESS SEGMENTS
 
     The Company operates in one business segment, which is to provide the
common carriage of freight over various worldwide routes.
 
     The assets of the Company, principally flight equipment, support its entire
worldwide transportation system and are not readily identifiable by geographic
area. Property and equipment, other than flight equipment, located in foreign
locations is not significant.
 
     Foreign sales accounted for 99%, 98% and 99% of total revenues for the
years ended December 31, 1997, 1996 and 1995, respectively. All foreign sales
were U.S. dollar denominated.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
13. PREFERRED STOCK
 
     The Board of Directors is authorized under the restated certificate of
incorporation to issue up to 10,000,000 shares of Preferred Stock in one or more
series and to fix the rights, preferences, privileges and restrictions thereof,
including dividend rights, dividend rates, conversion rights, voting rights,
terms of redemption, redemption prices, liquidation preferences and the number
of shares constituting any series or the designation of such series, without
further vote or action by the stockholders. The issuance of Preferred Stock may
have the effect of delaying, deferring or preventing a change in control of the
Company without further action by the stockholders. The issuance of Preferred
Stock with voting and conversion rights may adversely affect the voting power of
the holders of common stock, including the loss of voting control to others. At
present, the Company has no plans to issue any shares of Preferred Stock.
 
14. STOCK-BASED COMPENSATION PLANS
 
  Employee Stock Purchase Plan
 
     In 1995, the Company established an Employee Stock Purchase Plan (the
"Stock Purchase Plan"). Employees eligible to participate in the Stock Purchase
Plan are those who have completed at least one year of employment with the
Company, but excluding employees whose customary employment is not more than
five months in any calendar year or 20 hours or less per week. The Stock
Purchase Plan is administered by the Compensation Committee of the Board of
Directors of the Company which determines the terms and conditions under which
shares are offered and corresponding options granted under the Stock Purchase
Plan for any Purchase Period, as defined in the Stock Purchase Plan. Employees
may contribute up to 15% of their gross base compensation subject to certain
limitations. The price per share at which the common stock is purchased pursuant
to the Stock Purchase Plan is the lesser of 85% of the fair market value of the
common stock on the first or last day of the applicable Purchase Period. The
maximum number of shares of common stock which may be issued on the exercise of
options purchased under the Stock Purchase Plan is 1,000,000 shares. As of
December 31, 1997, 47,984 shares were issued at a weighted average cost of
$23.28 to 161 employees who have participated in the Stock Purchase Plan.
 
  1995 Stock Option Plan
 
     In 1995, the Company adopted the 1995 Stock Option Plan ("1995 Plan"),
whereby employees may be granted options, incentive stock options, share
appreciation rights, and restricted shares. The portion of the 1995 Plan
applicable to employees is administered by the Compensation Committee of the
Board of Directors of the Company which also establishes the terms of the
awards. The 1995 Plan also provides for certain automatic grants of nonqualified
stock options to non-employee directors which become exercisable on the date of
grant and expire on the tenth anniversary of the date of grant. Originally, an
aggregate of 1,800,000 shares were reserved for issuance in connection with
awards and director's options under the 1995 Plan. Following shareholder
approval, an additional 300,000 shares were reserved.
 
  Director Stock Plan
 
     In August 1996, the Company established the Director Stock Plan (the
"Director Plan"), which provides the Company's non-employee directors the option
to receive all or a portion of their quarterly remuneration in common stock
instead of cash. If a non-employee director elects at the commencement of any
quarter to receive his quarterly remuneration, or a portion thereof, in common
stock, the number of shares received is determined by dividing the average price
for the 30-day period immediately preceding the end of the quarter into the
amount of compensation earned for the quarter which the non-employee director
chooses not to receive in cash. The effective date of the Director Plan was
January 1, 1997. As of December 31, 1997, 861 shares were issued at a weighted
average cost of $27.62 to two directors who have participated in the Stock
Purchase Plan.

  Other
 
     In July 1995, options to purchase 125,000 and 71,430 shares of the
Company's common stock were granted to an officer ("July 1995 Grant"), who
subsequently resigned from his position with the Company to accept a position
with an affiliate of the Company, at exercise prices of $10.00 per share and
$14.00 per share, respectively.
 
  Statement of Financial Accounting Standards No. 123
 
     SFAS No. 123, "Accounting for Stock-Based Compensation," defines a fair
value based method of accounting for employee stock options or similar equity
instruments. However, SFAS No. 123 allows the continued measurement of
compensation cost for such plans using the intrinsic value based method
prescribed by Accounting Principals Board ("APB") Opinion No. 25, "Accounting
for Stock Issued to Employees," provided that pro forma disclosures are made of
net income or loss and net income or loss per share, assuming the fair value
based method of SFAS No. 123 had been applied. The Company has elected to
account for its stock-based compensation plans under APB Opinion No. 25;
accordingly, for purposes of the pro forma disclosures presented below, the
Company has computed the fair value of all options granted during 1997, 1996 and
1995, using the Black-Scholes pricing model and the following weighted average
assumptions:

15. PROFIT SHARING PLAN
 
     Employees who have been employed by the Company for at least twelve months
as full-time employees are eligible to participate in the Company's Profit
Sharing Plan, which was adopted in 1994. The Profit Sharing Plan provides for
payments to eligible employees in semiannual distributions based on the
Company's pretax profits. The Company is obligated to make an annual profit
sharing contribution of ten percent of the Company's pretax profits, which is
defined as net income before taxes, but excluding (i) any income or loss related
to charges or credits for unusual or infrequently occurring items or related to
intangible assets, and (ii) extraordinary items. Annual profit sharing
contributions may be in the form of cash or common stock of the Company. For the
years 1997, 1998 and 1999, beginning with an employee's thirteenth month of
employment, an employee is entitled to receive a guaranteed profit sharing
payment of 10% of salary, except for captains, who receive a guarantee of 20%.
The expense for the Profit Sharing Plan for the years ended December 31, 1997,
1996 and 1995 was $4,004,000, $6,779,000 and $2,768,000, respectively.
 
16. SUBSEQUENT EVENTS (UNAUDITED)
 
     In January and February 1998, pursuant to an early lease termination
agreement negotiated in November 1997, the Company delivered to Boeing for
modification to cargo configuration the aircraft acquired from Marine Midland in
December 1996 and the aircraft acquired from Citicorp in May 1997. These
aircraft are expected to be re-delivered to the Company in the second quarter
and early in the third quarter of

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
1998, respectively. The financing for the modification to cargo configuration is
secured under the Aircraft Credit Facility.
 
     In February 1998, the Company completed an offering of $538.9 million of
pass-through certificates, also known as enhanced equipment trust certificates
(the "EETCs"). The EETCs are not direct obligations of, or guaranteed by, the
Company and therefore will not be included in the Company's consolidated
financial statements. The cash proceeds from the transaction were deposited with
an escrow agent and will be used to finance (through either leveraged leases or
secured debt financings) the debt portion of the acquisition cost of five of the
10 new 747-400 freighter aircraft from Boeing scheduled to be delivered to the
Company during the period July 1998 through December 1998. In connection
therewith, the Company intends to seek certain owner participants who will
commit lease equity financing to be used in leveraged leases of such aircraft.
If any funds remain as deposits with the escrow agent for such EETCs at the end
of the delivery period, such funds will be distributed back to the
certificateholders. Such distribution will include a make-whole premium payable
by the Company. In November and December 1997, the Company entered into three
Treasury Note hedges, approximating $300 million of principal, for the purpose
of minimizing the risk associated with the fluctuations in interest rates, which
are the basis for the pricing of the EETCs which were priced in January 1998.
The effect of the hedge resulted in a deferred cost of $6.3 million, which will
be amortized over the expected twenty-year life associated with this financing.
 
     The Company is currently negotiating for the possibility of refinancing two
aircraft in the amount of approximately $86 million, currently financed under
the Aircraft Acquisition Credit Facility. There is no assurance that this
refinancing will be consummated.

Dear Sirs:

                 Atlas Air, Inc., a Delaware corporation (the "Company"),
proposes that Wilmington Trust Company, as trustee under each of the Original
Trusts (as defined below) (each, a "Trustee"), issue and sell to the placement
agents named in Schedule II hereto its pass through certificates in the
aggregate principal amounts and with the interest rates and final distribution
dates set forth on Schedule I hereto (the "Offered Certificates") on the terms
and conditions stated herein and in Schedule III.  As used herein, unless the
context otherwise requires, the term "Placement Agents" shall mean the firms
named as Placement Agents in Schedule II, and the term "you" shall mean Morgan
Stanley & Co.  Incorporated ("Morgan Stanley").

                 The Offered Certificates will be issued pursuant to three
separate pass through trust agreements, each to be dated as of February 9, 1998
(collectively, the "Original Pass Through Trust  Agreements") between the
Company and the Trustee.  The Original Pass Through Trust Agreements are
related to the creation and administration of Atlas Air, Inc. Pass Through
Trust Series 1998-1A (the "Class A Trust"), Atlas Air, Inc. Pass Through Trust
Series 1998-1B (the "Class B Trust") and Atlas Air, Inc. Pass Through Trust
Series 1998-1C (the "Class C Trust"; and together with the Class A Trust and
the Class B Trust, the "Original Trusts").

                 The cash proceeds of the offering of Offered Certificates by
each Original Trust will be paid to First Security Bank, National Association,
as escrow agent (the "Escrow Agent"), under an Escrow and Paying Agent
Agreement among the Escrow Agent,
<PAGE>   3
the Placement Agents, the Trustee of such Original Trust and Wilmington Trust
Company, as paying agent (the "Paying Agent"), for the benefit of the holders
of Offered Certificates issued by such Original Trust (each, an "Escrow
Agreement").  The Escrow Agent will deposit such cash proceeds (each, a
"Deposit") with ABN AMRO Bank N.V., acting through its Chicago branch (the
"Depositary"), in accordance with a Deposit Agreement relating to such Original
Trust (each, a "Deposit Agreement"), and will withdraw Deposits upon request to
allow the Trustee to purchase Equipment Notes (as defined in the Note Purchase
Agreement referred to herein) referred to herein from time to time pursuant to
a Note Purchase Agreement to be dated as of the Closing Date (the "Note
Purchase Agreement") among the Company, Wilmington Trust Company, as Trustee of
each of the Original Trusts, as Subordination Agent (as hereinafter defined)
and as Paying Agent, and the Escrow Agent.  Each Escrow Agent will issue
receipts to be attached to each related Offered Certificate ("Escrow Receipts")
representing each holder's fractional undivided interest in amounts deposited
with such Escrow Agent and will pay to such holders through the related Paying
Agent interest accrued on the Deposits and received by such Paying Agent
pursuant to the related Deposit Agreement at a rate per annum equal to the
interest rate applicable to the corresponding Offered Certificates.

                 On the earlier of (i) the first Business Day after June 30,
1999, or, if later, the fifth Business Day after the Delivery Period
Termination Date (as defined in the Note Purchase Agreement) and (ii) the fifth
Business Day after the occurrence of a Triggering Event (as defined in the
Intercreditor Agreement) (such Business Day, the "Trust Transfer Date"), each
of the Original Trusts will transfer and assign all of its assets and rights to
a newly-created successor trust with substantially identical terms except as
described in the Offering Memorandum (as hereinafter defined) (each, a
"Successor Trust" and, together with the Original Trusts, the "Trusts")
governed by three separate pass through trust agreements (collectively the
"Successor Pass Through Trust  Agreements" and, together with the Original Pass
Through Trust Agreements, the "Designated Agreements") between the Company and
the Trustee.  Each Offered Certificate outstanding on the Trust Transfer Date
will represent the same interest in the Successor Trust as the Offered
Certificate represented in the Original Trust.  Wilmington Trust Company
initially will also act as trustee of the Successor Trusts (each, a "Successor
Trustee").

                 Certain amounts of interest payable on the Offered
Certificates will be entitled to the benefits of separate liquidity facilities.
ABN AMRO Bank N.V., acting through its Chicago branch, in the case of the Class
A Trust (in such capacity, the "Class A Liquidity Provider") and Morgan Stanley
Capital Services, Inc., in the case of the Class B Trust and the Class C Trust
(the "Class B and C Liquidity Provider" and, together with the Class A
Liquidity Provider, the "Liquidity Providers") will enter into separate
revolving credit agreements with respect to each Original Trust (each, a
"Liquidity Facility") to be dated as of the Closing Date for the benefit of the
holders of the Offered Certificates.  The Liquidity Providers and the holders
of the Offered Certificates will be entitled to the benefits of an
Intercreditor Agreement to be dated as of the Closing Date (the "Intercreditor
Agreement")





                                       2

among the Trustees, Wilmington Trust Company, as subordination agent and
trustee thereunder (the "Subordination Agent"), and the Liquidity Providers.

                 The Offered Certificates will be offered without being
registered under the Securities Act of 1933, as amended (the "Securities Act"),
in reliance on exemptions therefrom.

                 Each Placement Agent 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,
pursuant to which the Company will file a registration statement (the
"Registration Statement") with the Securities and Exchange Commission (the
"Commission") registering the Exchange Certificates referred to in such
Registration Rights Agreement (the "Exchange Certificates") or the Offered
Certificates under the Securities Act.

                 In connection with the sale of the Offered Certificates, the
Company has prepared a preliminary offering memorandum (the "Preliminary
Memorandum") and will prepare a final offering memorandum (the "Final
Memorandum" and, with the Preliminary Memorandum, each, a "Memorandum") setting
forth or including a description of the terms of the Offered Certificates, the
terms of the offering and a description of the Company and its business.

                 Capitalized terms not otherwise defined in this Agreement
shall have the meanings specified therefor in the Original Pass Through Trust
Agreements or in the Note Purchase Agreement or the Intercreditor Agreement
referred to in the Designated Agreements; provided that, as used in this
Agreement, the term "Operative Agreements" shall mean the Deposit Agreements,
the Escrow Agreements, the Intercreditor Agreement, the Liquidity Facilities,
the Designated Agreements, the Registration Rights Agreement and the Financing
Agreements (as defined in the Intercreditor Agreement).

                 1.       Representations and Warranties.  (a)  The Company
represents and warrants to, and agrees with each Placement Agent that:

                 (i)      The Preliminary Memorandum does not contain and the
Final Memorandum, in the form used by the Placement Agent to confirm sales and
on the Closing Date, 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.  The
preceding sentence does not apply to statements in or omissions from either
Memorandum based upon written information furnished to the Company by any
Placement Agent through Morgan Stanley expressly for use therein ("Placement
Agent Information").  The Company hereby confirms that it has authorized the
use of both of the Memoranda in connection with the offer and resale of the
Certificates by the Placement Agents.

existing as a corporation in good standing under the laws of the jurisdiction
of its incorporation, has the corporate power and authority to own its property
and to conduct its business as described in each Memorandum and to perform its
obligations under this Agreement and the Operative Documents to which it is, or
is to be, a party; the Company is duly qualified to transact business and is in
good standing in each jurisdiction in which the conduct of its business or its
ownership or leasing of property requires such qualification, except to the
extent that the failure to be so qualified or be in good standing would not
have a material adverse effect on the Company and its subsidiaries, taken as a
whole (an "Atlas Material Adverse Effect").

Atlas Freighter Leasing, Inc., Atlas Freighter Leasing II, Inc., Atlas Air
Services Limited,  LHC Properties, Inc., Atlas Flightlease, Inc. and Genessee

the laws of the jurisdiction of its incorporation with corporate power and
authority under such laws to own, lease and operate its properties and conduct
its business; and each Subsidiary is duly qualified to transact business as a
foreign corporation and is in good standing in each other jurisdiction in which
it owns or leases property of a nature, or transacts 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 an Atlas Material Adverse
Effect.  All of the outstanding shares of capital stock of each Subsidiary have
been duly authorized and validly issued and are fully paid and non-assessable

is to be, a party, have each been duly authorized by the Company, are or will
be substantially in the form heretofore supplied to you and, assuming that such
Operative Agreements have been duly authorized, executed and delivered by, and
constitute the legal, valid and binding obligations of, each other party

be attached to the related Offered Certificates.

                 (b)      The Company is advised by you that the Placement
Agents propose to make an offering of the Offered Certificates purchased by the
Placement Agents hereunder on the terms to be set forth in the Final Memorandum
as soon as practicable after this Agreement has been entered into as in your
judgment is advisable.

                 (c)      As compensation to the Placement Agents for their
respective commitments and obligations hereunder in respect of the Offered
Certificates, including their respective undertakings to distribute the Offered
Certificates, the Company will pay to each Placement Agent an amount equal to
that percentage of the aggregate principal amount of Offered Certificates
purchased by such Placement Agent (as set forth in Schedule II).  Such payment
will be made on the Closing Date simultaneously with the issuance and sale of
the Offered Certificates (with attached Escrow Receipts) to the Placement
Agents.  Payment of such compensation shall be made by Federal funds check or
other immediately available funds.

Sterling at 599 Lexington Avenue, New York, New York 10022-6069 at 10:00 A.M.
on February 9, 1998 or such other date, time and place as may be agreed upon by
the Company and you (such date and time of delivery and payment for the Offered
Certificates (with attached Escrow Receipts) being herein called the "Closing
Date").  Delivery of the Offered Certificates (with attached Escrow Receipts)
issued by each Original Trust shall be made to your account at The Depository
Trust Company ("DTC") for the respective accounts of the several Placement
Agents against payment by the Placement Agents of the purchase price thereof.
Payment for the Offered Certificates issued by each Original Trust and the
related Escrow Receipts attached thereto shall be made by the Placement Agents

New York, New York not later than 1:00 P.M. on the business day prior to the

                 (f)      It is understood that each Placement Agent has
authorized you for its account, to accept delivery of, receipt for, and make
payment of the purchase price for, the Offered Certificates (with attached
Escrow Receipts) that it has agreed to purchase.  You, individually and not as
a representative, may (but shall not be obligated to) make payment of the
purchase price for the Offered Certificates to be purchased by any Placement
Agent whose check or checks shall not have been received by the Closing Date.

                 3.       Conditions to Closing.  The obligations of the
Placement Agents under this Agreement to purchase the Offered Certificates will
be subject to the following conditions:

the Closing Date,

                 (i)      there shall not have occurred any downgrading, nor
         shall any 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 of the Company's securities, including the Offered Certificates,
         by any "nationally recognized statistical rating organization", as
         such term is defined for purposes of Rule 436(g)(2) under the
         Securities Act; and

                 (ii)     there shall not have occurred any change, or any

         forth in the Final Memorandum (exclusive of any amendments or
         supplements thereto subsequent to the date of this Agreement) that, in
         your judgment, is material and adverse and that makes it, in your
         judgment, impracticable to market the Offered Certificates on the
         terms and in the manner contemplated in the Final Memorandum.

                 (b)      You shall have received on the Closing Date a

                 (a)      To deliver to each Placement Agent, without charge,
         from time to time, as many copies of the Preliminary Memorandum as
         such Placement Agent may reasonably request, and the Company hereby
         consents to the use of such copies for purposes permitted by the

         or supplement the Final Memorandum in order to make the statements
         therein, in the light of the circumstances when such Memorandum is
         delivered to a purchaser, not misleading, or if, with the opinion of
         counsel to the Placement Agents it is necessary to amend or supplement
         such Memorandum to comply with applicable law, forthwith to prepare
         and furnish, at their own expense, to the Placement Agents, either
         amendments or supplements to such Memorandum so that the statements in
         such Memorandum as so amended or supplemented will not, in the light
         of the circumstances when such Memorandum is delivered to a purchaser,
         be misleading or so that such Memorandum, as so amended or
         supplemented, will comply with applicable law.

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 the Company that would permit a public
         offering of the Offered Certificates, or possession or distribution of
         either Memorandum or any other offering or publicity material relating
         to the Offered Certificates, in any country or jurisdiction where
         action for that purpose is required;

                 (ii)     it will comply with all applicable laws and
         regulations in each jurisdiction in which it acquires, offers, sells
         or delivers Offered Certificates or has in its possession or
         distributes either Memorandum or any such other material, in all cases
         at its own expense;

                 (iii)    the Offered Certificates 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 under the Securities
         Act or pursuant to an exemption from the registration requirements of
         the Securities Act;





                                       16
<PAGE>   18
                 (iv)     it has offered the Offered Certificates and will
         offer and sell the Offered Certificates (A) as part of its
         distribution at any time and (B) otherwise until 40 days after the

         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 Placement Agent, 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 Offered Certificates, and any the
         Placement Agent, its Affiliates and any such persons have complied and
         will comply with the offering restrictions requirements of

                 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 meanings given to them by Regulation S.

                 7.       Indemnification and Contribution.  (a)  The Company
agrees to indemnify and hold harmless each Placement Agent, and each person, if
any, who controls any Placement Agent 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, any Placement Agent, from and against any
and all losses, claims, damages and liabilities (including, without limitation,
any legal or other expenses reasonably incurred by any Placement Agent 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 either 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 incurred by any Placement Agent are
caused by any such untrue statement or omission or alleged untrue statement or
omission based upon information relating to the Placement Agents (and, in the
case of such losses, claims, damages or liabilities incurred by Morgan Stanley,
by any such untrue statement or omission or alleged untrue statement or
omission based upon information relating to the Class B and C Liquidity
Provider or to Morgan Stanley, Dean Witter, Discover & Co.) furnished to the
Company in writing by the Placement Agents through you expressly for use
therein; provided, however, that the foregoing indemnity agreement with respect
to the Preliminary Memorandum shall not inure to the benefit of any Placement
Agent from whom the person asserting any such losses, claims, damages or
liabilities purchased Offered Certificates, or any person controlling such
Placement Agent, if a copy of the Final Memorandum (as then amended or
supplemented if the Company shall have furnished any amendments thereto) was
not sent or given by or on behalf of such Placement Agent to such person, if
required by law so to have been delivered, at or prior to the written
confirmation of the sale of the Offered Certificates, and the Final Memorandum
(as so amended or supplemented) would have cured the defect giving rise to such
losses, claims, damages or liabilities, unless such failure is the result of
noncompliance by the Company with Section 5(a) hereof.

                 (b)      The Placement Agents agree, severally and not
jointly, to indemnify and hold harmless the Company, each of its directors, its
officers and each person, if any, who controls the Company 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 the





                                       18
<PAGE>   20
Company to the Placement Agents, but only with reference to information
relating to the Placement Agents furnished to the Company in writing by the
Placement Agents through you expressly for use in either 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 any of 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 Morgan Stanley & Co. Incorporated in the case of parties indemnified
pursuant to paragraph (a) above and by 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 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 60 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





                                       19
<PAGE>   21
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 Company on the one
hand and the Placement Agents on the other hand from the offering of such
Offered Certificates or (ii) if the allocation 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 Company on the one hand and the Placement Agents 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 Company on the
one hand and the Placement Agents on the other hand in connection with the
offering of such Offered Certificates shall be deemed to be in the same
respective proportions as (in the case of the Company) the net proceeds from
the offering of such Offered Certificates (before deducting expenses) received
by the Trusts and (in the case of the Placement Agents) the total discounts and
commissions received by the Placement Agents in respect of the Offered
Certificates bear to the aggregate offering price of such Offered Certificates.
The relative fault of the Company, on the one hand, and the Placement Agents,
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 the Company or the Placement Agents and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.  The Placement Agents' respective obligations to
contribute pursuant to this Section 7 are several in proportion to the
respective principal amount of Offered Certificates they have purchased
hereunder, and not joint.

                 (e)      The Company and the Placement Agents 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 Placement Agents shall
not be required to contribute any amount in excess of the amount by which the
total price at which the Offered Certificates resold by it in the initial
placement of such Offered Certificates were offered to investors exceeds the
amount of any damages that the Placement Agents 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.  The
indemnity and contribution provisions contained in this Section 7 and the
representations and warranties of the Company contained in this Agreement shall
remain operative and in full force and effect regardless of (i) any termination
of this Agreement,





                                       20
<PAGE>   22
(ii) any investigation made by or on behalf of the Placement Agents or any
person controlling any Placement Agent, by or on behalf of the Company, its
officers or directors or any person controlling the Company and (iii)
acceptance of and payment for any of the Offered Certificates.  The remedies
provided for in this Section 7 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.

                 8.       Termination.  This Agreement shall be subject to
termination by notice given by you to the Company, if (a) after the execution
and delivery of this Agreement and prior to the Closing Date (i) trading
generally shall have been suspended or materially limited on or by, as the case
may be, any of the New York Stock Exchange, the American Stock Exchange, the
National Association of Securities Dealers, Inc., the Chicago Board of Options
Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade, (ii)
trading of any securities of the Company shall have been suspended on any
exchange or in any over-the-counter market, (iii) a general moratorium on
commercial banking activities in New York shall have been declared by either
Federal or New York State authorities or (iv) there shall have occurred any
outbreak or escalation of hostilities or any change in financial markets or any
calamity or crisis that, in your judgment, is material and adverse and (b) in
the case of any of the events specified in clauses (a)(i) through (iv), such
event singly or together with any other such event makes it, in your judgment,
impracticable to market the Offered Certificates on the terms and in the manner
contemplated in the Final Memorandum.

                 9.       All notices and other communications under this
Agreement shall be in writing, and, if sent to the Placement Agents, shall be
mailed, delivered or sent by facsimile transmission to:

                 10.      This Agreement shall become effective upon the
execution and delivery hereof by the parties hereto.

                 If, on the Closing Date, any one or more of the Placement
Agents shall fail or refuse to purchase Offered Certificates that it or they
have agreed to purchase hereunder on such date, and the aggregate principal
amount of Offered Certificates which such defaulting Placement Agent or
Placement Agents agreed but failed or refused to purchase is not more than
one-tenth of the aggregate principal amount of Offered Certificates to be
purchased on such date, the other Placement Agents shall be obligated severally
in the proportions that the principal amount of Offered Certificates set forth
opposite their respective names in Schedule I bears to the aggregate principal
amount of Offered Certificates set forth opposite the names of all such
non-defaulting Placement Agents, or in such other proportions as you may
specify, to purchase the Offered Certificates which such defaulting Placement
Agent or Placement Agents agreed but failed or refused to purchase on such
date; provided, that in no event shall the principal amount of Offered
Certificates that any Placement Agent has agreed to purchase pursuant to this
Agreement be increased pursuant to this Section 10 by an amount in excess of
one-ninth of such principal amount of Offered Certificates without the written
consent of such Placement Agent.  If on the Closing Date any Placement Agent or
Placement Agents shall fail or refuse to purchase Offered Certificates which it
or they have agreed to purchase on such date and the aggregate principal amount
of Offered Certificates with respect to which such default occurs is more than
one-tenth of the aggregate principal amount of Offered Certificates to be
purchased on such date, and arrangements satisfactory to you and the Company
for the purchase of such Offered Certificates are not made within 36 hours
after such default, this Agreement shall terminate without liability on the
part of any non-defaulting Placement Agent or of the Company.  In any such case
either you or the Company shall have the right to postpone the Closing Date,
but in no event for longer than seven days, in order that the required changes,
if any, in the Final Memorandum or in any other documents or arrangements may
be effected.  Any action taken under this paragraph shall not relieve any
defaulting Placement Agent from liability in respect of any default of such
Placement Agent under this Agreement.

                 If this Agreement shall be terminated by the Placement Agents,
or any of them, because of any failure or refusal on the part of the Company to
comply with the terms or to fulfill any of the conditions of this Agreement, or
if for any reason the Company shall be unable to perform its obligations under
this Agreement, the Company will reimburse the Placement Agents or such
Placement Agents as have so terminated this Agreement with respect to
themselves, severally, for all out-of-pocket expenses (including the fees and





                                       22
<PAGE>   24
disbursements of their counsel) reasonably incurred by such Placement Agents in
connection with this Agreement or the offering contemplated hereunder.

                 11.      This Agreement may be signed in any number of
counterparts, each of which shall be an original, with the same effect as if
the signatures thereto and hereto were upon the same instrument.

                 This Agreement shall be governed by and construed in
accordance with the internal laws of the State of New York.

                 The headings of the sections of this Agreement have been
inserted for convenience of reference only and shall not be deemed a part of
this Agreement.

                 This Agreement is made pursuant to the Placement Agreement
dated January 26, 1998, among the Company and the Placement Agents (the
"Placement Agreement"), which provides for the sale by the Trustee (as defined

enter into the Placement Agreement, the Company has agreed to provide to the
Placement Agents and their direct and indirect transferees the registration
rights set forth in this Agreement.  The execution of this Agreement is a
condition to the closing under the Placement Agreement.

                 The Certificates will be issued pursuant to three separate
pass through trust agreements, each to be dated as of February __, 1998
(collectively the "Original Pass Through Trust  Agreements") between the
Company and Wilmington Trust Company, as trustee under each of the Original
Trusts (as defined below) (each a "Trustee").  The Original Pass Through Trust
Agreements are related to the creation and administration of Atlas Air, Inc.
Pass Through Trust Series 1998-1A (the "Class A Trust"), Atlas Air, Inc. Pass
Through Trust Series 1998-1B (the "Class B Trust") and Atlas Air, Inc. Pass

A Trust and the Class B Trust and the Class C Trust, the "Original Trusts").

among the Escrow Agent, the Placement Agents, the Trustee of such Original
Trust and Wilmington Trust Company, as paying agent (the "Paying Agent"), for

Trust.  The Escrow Agent will deposit such cash proceeds (each, a "Deposit")
with the Depositary, in accordance with a Deposit Agreement relating to such
Original Trust (each, a "Deposit Agreement"), and will withdraw Deposits upon

fractional undivided interest in amounts deposited with such Escrow Agent and
will pay to such holders through the related Paying Agent interest accrued on
the Deposits and received by such Paying Agent pursuant to the related Deposit
Agreement at a rate per annum equal to the interest rate applicable to the
corresponding Certificates.

                 On the Trust Transfer Date (as defined in the Placement
Agreement), each of the Original Trusts will transfer and assign all of its
assets and rights to a newly-created successor trust with substantially
identical terms except as described in the Final Memorandum (as defined in the

Trusts, the "Trusts") governed by three separate pass through trust agreements
(collectively the "Successor Pass Through Trust  Agreements" and, together with
the Original Pass Through Trust Agreements, the "Trust Agreements") between the
Company and the Trustee.  Each Certificate outstanding on the Trust Transfer
Date will represent the same interest in the Successor Trust as the Certificate

                 2.       Registration Under the 1933 Act.  (a)  To the extent
not prohibited by any applicable law or applicable interpretation of the Staff
of the SEC, the Company shall use its best efforts (i) to cause to be filed
after the Closing Date an Exchange Offer Registration Statement covering the
offer to the Holders to exchange (A) all of the Class A Registrable
Certificates for Class A Exchange Certificates, (B) all of the Class B
Registrable Certificates for Class B Exchange Certificates, (C) all of the
Class C Registrable Certificates for Class C Exchange Certificates (ii) to have
such Registration Statement remain effective until the closing of the Exchange
Offer.  The Company shall commence the Exchange Offer promptly after the
Exchange Offer Registration Statement has been declared effective by the SEC
and use its best efforts to have the Exchange Offer consummated not later than
60 days after such effective date.  The Company shall, or shall cause the
Trustees to, commence the Exchange Offer by mailing the related exchange offer
Prospectus and accompanying documents to each Holder stating, in addition to
such other disclosures as are required by applicable law:
<PAGE>   37
                                      A-10

                 (i)      that the Exchange Offer is being made pursuant to
         this Registration Rights Agreement and that all Registrable
         Certificates validly tendered will be accepted for exchange;

                 (ii)     the dates of acceptance for exchange (which shall be
         each business day during a period of at least 30 days from the date
         such notice is mailed) (the "Exchange Dates");

                 (iii)    that any Registrable Certificate not tendered will
         remain outstanding and continue to accrue interest, but will not
         retain any rights under this Registration Rights Agreement;

                 (iv)     that Holders electing to have a Registrable
         Certificate exchanged pursuant to the Exchange Offer will be required
         to surrender such Registrable Certificate, together with the enclosed
         letters of transmittal, to the institution and at the address (located
         in the Borough of Manhattan, The City of New York) specified in the
         notice prior to the close of business on the last Exchange Date; and

                 (v)      that Holders will be entitled to withdraw their
         election, not later than the close of business on the last Exchange
         Date, by sending to the institution and at the address (located in the
         Borough of Manhattan, The City of New York) specified in the notice, a
         telegram, telex, facsimile transmission or letter setting forth the
         name of such Holder, the principal amount of Registrable Certificates
         delivered for exchange, and a statement that such Holder is
         withdrawing his election to have such Certificates exchanged.

                 As soon as practicable after the last Exchange Date, the
         Company shall or shall cause the Trustees to:

                 (i)      accept for exchange Registrable Certificates or
         portions thereof tendered and not validly withdrawn pursuant to the
         Exchange Offer;

                 (ii)     deliver, or cause to be delivered, to the Class A
         Trustee for cancellation all Class A Registrable Certificates or
         portions thereof so accepted for exchange by the Company, and issue,
         and cause the Class A Trustee to promptly authenticate and mail to
         each Class A Holder, Class A Exchange Certificates equal in principal
         amount to the principal amount of the Class A Registrable Certificates
         surrendered by such Class A Holder;

                 (iii)    deliver, or cause to be delivered, to the Class B
         Trustee for cancellation all Class B Registrable Certificates or
         portions thereof so accepted for exchange by the Company, and issue,
         and cause the Class B Trustee to promptly
<PAGE>   38
                                      A-11

         authenticate and mail to each Class B Holder, Class B Exchange
         Certificates equal in principal amount to the principal amount of the
         Class B Registrable Certificates surrendered by such Class B Holder;
         and

                 (iv)     deliver, or cause to be delivered, to the Class C
         Trustee for cancellation all Class C Registrable Certificates or
         portions thereof so accepted for exchange by the Company, and issue,
         and cause the Class C Trustee to promptly authenticate and mail to
         each Class C Holder, Class C Exchange Certificates equal in principal
         amount to the principal amount of the Class C Registrable Certificates
         surrendered by such Class C Holder.

The Company shall use its best efforts 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, rules 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 Placement Agents of the names and addresses of the Holders to
whom the Exchange Offer is made, and the Placement Agents shall have the right,
subject to applicable law, to contact such Holders and otherwise facilitate the
tender of Registrable Certificates in the Exchange Offer.

                 (b)      In the event that (i) the Company determines 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 within 30 days of the effectiveness of an Exchange Offer
Registration Statement or (iii) the Exchange Offer has been completed and in
the opinion of counsel for the Placement Agents a Registration Statement must
be filed and a Prospectus must be delivered by the Placement Agents in
connection with any offering or sale of Registrable Certificates, the Company
shall use its best efforts 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 Certificates, and to have such
Shelf Registration Statement declared effective by the SEC.  The Company agrees
to use its best efforts to keep the Shelf Registration Statement continuously
effective until the second anniversary of the Closing Date or such shorter
period that will terminate when all of the Registrable Certificates covered by
the Shelf Registration Statement have been sold pursuant to the Shelf
Registration Statement.  The Company further agrees 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 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 its best
efforts to cause any such
<PAGE>   39
                                      A-12

amendment to become effective and such Shelf Registration Statement to become
usable as soon as thereafter practicable.  The Company agrees to furnish to the
Holders of Registrable Certificates copies of any such supplement or amendment
promptly after its being used or filed with the SEC.

                 (c)      The Company 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
Certificates 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 Certificates 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 Shelf Registration Statement will be deemed not to have become
effective during the period of such interference until the offering of
Registrable Certificates pursuant to such Registration Statement may legally
resume.  In the event that neither the consummation of the Exchange Offer nor
the declaration by the Commission of a Shelf Registration to be effective (each
a "Registration Event") occurs on or prior to the 180th day after the date of
the issuance of the Registrable Certificates, the interest rate per annum borne
by the Certificates shall be increased by 0.50%, effective from and including
August __, 1998, to but excluding the date on which a Registration Event
occurs.  In the event that the Shelf Registration Statement ceases to be
effective at any time during the period specified by Section 2(b) hereof for
more than 60 days, whether or not consecutive, during any 12-month period, the
interest rate borne by the Certificates shall be increased by 0.50% per annum
from the 61st day of the applicable 12-month period such Shelf Registration
Statement ceases to be effective until such time as the Shelf Registration
Statement again becomes effective.

                 (e)      Without limiting the remedies available to the
Placement Agents and the Holders, the Company acknowledges that any failure by
the Company to comply with its obligations under Section 2(a) and Section 2(b)
hereof may result in material irreparable injury to the Placement Agents 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, each Placement Agent or any Holder may obtain such relief
as may be required to specifically enforce the Company's obligations under
Section 2(a) and Section 2(b) hereof.

                 3.       Registration Procedures.  In connection with the
obligations of the Company with respect to the Registration Statements pursuant
to Section 2(a) and Section 2(b) hereof, the Company shall as expeditiously as
possible:

                 (a)      prepare and file with the SEC a Registration
         Statement on the appropriate form under the 1933 Act, which form (x)

         Registration, be available for the sale of the Registrable
         Certificates by the selling Holders thereof and (z) shall comply as to

         form and include all financial statements required by the SEC to be

         Statement to become effective and remain effective in accordance with
         Section 2 hereof;

                 (b)      prepare and file with the SEC such amendments and
         post-effective amendments to each Registration Statement as may be
         necessary to (x) keep such Registration Statement effective for the
         applicable period under this Registration Rights Agreement, and (y)
         cause each Prospectus to be supplemented by any required prospectus
         supplement and, as so supplemented, to be filed pursuant to Rule 424
         under the 1933 Act and (z) keep each Prospectus current during the
         period described under Section 4(3) and Rule 174 under the 1933 Act
         that is applicable to transactions by brokers or dealers with respect
         to the Registrable Certificates or Exchange Certificates;

                 (c)      in the case of a Shelf Registration, furnish to each
         Holder of Registrable Certificates, to counsel for the Placement
         Agents, to counsel for the Holders and to each Underwriter of an
         Underwritten Offering of Registrable Certificates, if any, and each
         such Underwriter's Counsel, 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 Certificates; and the
         Company consents 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 Certificates and any such Underwriters
         in connection with the offering and sale of the Registrable
         Certificates 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 Certificates under all applicable state securities or
         "blue sky" laws of such jurisdictions as any Holder of Registrable
         Certificates 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
<PAGE>   41
                                      A-14

         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 Certificates owned by such Holder; provided, however, that
         the Company shall not 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) subject
         itself to taxation in any such jurisdiction if it is not so subject;

                 (e)      in the case of a Shelf Registration, notify each
         Holder of Registrable Certificates, counsel for the Holders and
         counsel for the Placement Agents 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 have been filed and become 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 Certificates
         covered thereby, the representations and warranties of the Company
         contained in any underwriting agreement, securities sales agreement or
         other similar agreement, if any, relating to such offering cease to be
         true and correct in all material respects or if the Company receives
         any notification with respect to the suspension of the qualification
         of the Registrable Certificates 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 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 Certificates, without charge, at least one
         conformed copy of each
<PAGE>   42
                                      A-15

         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 Certificates to facilitate the
         timely preparation and delivery of certificates representing
         Registrable Certificates to be sold and not bearing any restrictive
         legends and enable such Registrable Certificates to be in such
         denominations (consistent with the provisions of the Applicable Trust
         Agreement) 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 Certificates;

                 (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 Certificates, 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 agrees 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
         Placement Agents and their counsel (and, in the case of a Shelf
         Registration Statement, the Holders and their counsel) and make such
         of the representatives of the Company as shall be reasonably requested
         by the Placement Agents or their 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 Placement Agents
         and their counsel (and, in 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 Placement Agents or their counsel
         (and, in the case of a Registration Statement, the Holders or their
         counsel) shall object;
<PAGE>   43
                                      A-16

                 (k)      obtain a CUSIP number for all Exchange Certificates
         or Registrable Certificates, as the case may be, not later than the
         effective date of a Registration Statement;

                 (l)      cause the Trust Agreements to be qualified under the
         Trust Indenture Act of 1939, as amended (the "TIA") in connection with
         the registration of the Exchange Certificates or Registrable
         Certificates, as the case may be, cooperate with the Trustees and the
         Holders to effect such changes to the Trust Agreements as may be
         required for the Trust Agreements to be so qualified in accordance
         with the terms of the TIA and execute, and use its best efforts to
         cause the Trustees 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 Trust Agreements 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
         Certificates, 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 cause the respective
         officers, directors and employees of the Company 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 its best
         efforts to cause all Registrable Certificates to be listed on any
         securities exchange or any automated quotation system on which similar
         securities issued by the Company are then listed if requested by the
         Majority Holders, to the extent such Registrable Certificates satisfy
         applicable listing requirements;

                 (o)      use its best efforts to cause the Exchange
         Certificates or Registrable Certificates, 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
         Certificates 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 satisfactory notification of the matters to

         customary agreements and take all such other actions in connection
         therewith (including those requested by the Holders of a majority of
         the class of Registrable Certificates being sold) in order to expedite
         or facilitate the disposition of such Registrable Certificates
         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
         Certificates with respect to the business of the Company and its
         subsidiaries, the Registration Statement, Prospectus and documents
         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
         (which counsel and opinions, in form, scope and substance, shall be
         reasonably satisfactory to the Holders and such Underwriters and their

         in opinions requested in underwritten offerings, (iii) obtain "cold
         comfort" letters from the independent certified public accountants of

         Company for which financial statements and financial data are or are
         required to be included in the Registration Statement) addressed to

         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 Certificates being
         sold or the Underwriters, and which are customarily delivered in
         underwritten offerings, to evidence the continued validity of the
         representations and warranties of the Company 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 may
require each Holder of Registrable Certificates to furnish to the Company such
information regarding the Holder and the proposed distribution by such Holder
of such Registrable Certificates as the Company 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 of the happening of
any event of the kind described in Section 3(e)(v) hereof, such Holder will
forthwith discontinue disposition of Registrable Certificates pursuant to a
Shelf 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 the
Company's expense) all copies in its possession, other than permanent file
copies then in such Holder's
<PAGE>   45
                                      A-18

possession, of the Prospectus covering such Registrable Certificates current at
the time of receipt of such notice.  If the Company shall give any such notice
to suspend the disposition of Registrable Certificates pursuant to a
Registration Statement, the Company shall extend the period during which the
Registration Statement shall be maintained effective pursuant to this
Registration Rights 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 Certificates covered by a Shelf
Registration Statement who desire to do so may sell such Registrable
Certificates 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 Certificates 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 Certificates for its own account in the Exchange Offer in
exchange for Certificates that were acquired by such broker-dealer as a result
of market making or other trading activities (a "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 Certificates.

                 The Company understands 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
Certificates, without naming the Participating Broker-Dealers or specifying the
amount of Exchange Certificates 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 Certificates for
their own accounts, so long as the Prospectus otherwise meets the requirements
of the 1933 Act.

                 (b)      In light of Section 4(a) above, notwithstanding the
other provisions of this Registration Rights Agreement, the Company agrees that
the provisions of this Registration Rights 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 Placement Agents or by one or more Participating Broker-Dealers, in each
case as provided in clause (ii) below, in order to expedite or
<PAGE>   46
                                      A-19

facilitate the disposition of any Exchange Certificates by Participating
Broker-Dealers consistent with the positions of the Staff recited in Section
4(a) above; provided that:

                 (i)      the Company 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 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 Registration Rights 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 by the Placement Agents or with the reasonable
         request in writing to the Company by one or more broker-dealers who
         certify to the Placement Agents and the Company in writing that they
         anticipate that they will be Participating Broker-Dealers; provided
         that in connection with such application of the Shelf Registration
         procedures set forth in Section 3 to an Exchange Offer Registration,
         the Company shall be obligated (x) to deal only with one entity
         representing the Participating Broker-Dealers, which shall be Morgan
         Stanley 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 Placement
         Agents 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 Placement Agents shall have no liability to the
Company or any Holder with respect to any request that it may make pursuant to
Section 4(b) above.

                 5.       Indemnification and Contribution.         (a)  The
Company agrees to indemnify and hold harmless each Placement Agent, each Holder
and each person, if any, who controls any Placement Agent 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, any Placement Agent or
any Holder, from and against all losses, claims, damages and liabilities
(including, without limitation, any legal or other expenses reasonably incurred
by any Placement Agent, 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 Certificates or Registrable
<PAGE>   47
                                      A-20

Certificates 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 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 Placement Agents or any Holder
(and, in the case of such losses, claims, damages or liabilities incurred by
Morgan Stanley, by any such untrue statement or omission or alleged untrue
statement or omission based upon information relating to Morgan Stanley Capital
Services, Inc. or to Morgan Stanley, Dean Witter, Discover & Co.) furnished to
the Company in writing by the Placement Agents or any selling Holder expressly
for use therein, provided, however, that the foregoing indemnity agreement with
respect to the Preliminary Memorandum shall not inure to the benefit of any
Placement Agent from whom the person asserting any such losses, claims, damages
or liabilities purchased Offered Certificates, or any person controlling such
Placement Agent, if a copy of the Final Memorandum (as then amended or
supplemented if the Company shall have furnished any amendments thereto) was
not sent or given by or on behalf of such Placement Agent to such person, if
required by law so to have been delivered, at or prior to the written
confirmation of the sale of the Offered Certificates (as so amended or
supplemented) would have cured the defect giving rise to such losses, claims,
damages or liabilities, unless such failure is the result of noncompliance by
the Company with Section 5(a) of the Placement Agreement.  In connection with
any Underwritten Offering permitted by Section 3, the Company 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 1933 Act and the 1934 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, each Placement Agent, 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, any
Placement Agent or 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 to the Placement Agents and the
Holders, but only with reference to information relating to such Holder
furnished to the Company 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).
<PAGE>   48
                                      A-21

                 (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 of 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 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 Placement Agents and all persons, if any, who control any
Placement Agent within the meaning of either Section 15 of the 1933 Act or
Section 20 of the 1934 Act, (b) the fees and expenses of more than one separate
firm (in addition to any local counsel) for the Company, its directors, its
officers who sign the Registration Statement and each person, if any, who
controls the Company 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 Placement Agents
and persons who control any Placement Agent, such firm shall be designated in
writing by the Placement Agents.  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.  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 60 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
<PAGE>   49
                                      A-22

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 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 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 Certificates of such Holder that were registered pursuant
to a Registration Statement.

                 (e)      The Company 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 Certificates 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 Placement Agents, any Holder
<PAGE>   50
                                      A-23

or any person controlling any Placement Agent or any Holder, or by or on behalf
of the Company, its officers or directors or any person controlling the
Company, (iii) acceptance of any of the Exchange Certificates and (iv) any sale
of Registrable Certificates pursuant to a Shelf Registration Statement.

                 6.       Miscellaneous.  (a)  No Inconsistent Agreements.  The
Company has not entered into, and on or after the date of this Registration
Rights Agreement will not enter into, any agreement which is inconsistent with
the rights granted to the Holders of Registrable Certificates in this
Registration Rights 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 other issued and outstanding securities under any such agreements.

                 (b)      Amendments and Waivers.  The provisions of this
Registration Rights 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 has obtained the
written consent of Holders of at least a majority in aggregate principal amount
of the outstanding Registrable Certificates 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 Certificates 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 Placement Agents, the address set forth in the Placement Agreement, and
(ii) if to the Company, initially at the Company's address set forth in the
Placement Agreement and thereafter at such other address, notice of which is
given in accordance with the provisions of this Section 6(c).

                 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 each Trustee,
at the address specified in the Applicable Trust Agreement.
<PAGE>   51
                                      A-24

                 (d)      Successors and Assigns.  This Registration Rights
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 Certificates in violation of the terms of the
Placement Agreement or the Trust Agreements.  If any transferee of any Holder
shall acquire Registrable Certificates, in any manner, whether by operation of
law or otherwise, such Registrable Certificates shall be held subject to all of
the terms of this Registration Rights Agreement, and by taking and holding such
Registrable Certificates, such Person shall be conclusively deemed to have
agreed to be bound by and to perform all of the terms and provisions of this
Registration Rights Agreement and such Person shall be entitled to receive the
benefits hereof. The Placement Agents (in their capacity as Placement Agents)
shall have no liability or obligation to the Company with respect to any
failure by any other Holder to comply with, or any breach by any other Holder
of, any of the obligations of such other Holder under this Registration Rights
Agreement.

                 (e)      Purchases and Sales of Certificates. The Company
shall not, and shall use its best efforts to cause its affiliates (as defined
in Rule 405 under the 1933 Act), not to purchase and then resell or otherwise
transfer any Certificates.

                 (f)      Third Party Beneficiary.  The Holders shall be third
party beneficiaries to the agreements made hereunder and shall have the right
to enforce such agreements directly to the extent they deem such enforcement
necessary or advisable to protect their rights hereunder.

                 (g)      Counterparts.  This Registration Rights 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 Registration Rights
Agreement are for convenience of reference only and shall not limit or
otherwise affect the meaning hereof.

                 (i)      Governing Law.  This Registration Rights 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.

be reasonably requested by the Company in connection with the Company
satisfying its obligations arising under this Agreement.

                  [Form of Opinion of Cahill Gordon & Reindel]



                             February       ,     1998


To Each of the Persons Listed

Receipts (the "Class C Escrow Receipts" and, together with the Class A Escrow
Receipts and the Class B Escrow Receipts, the "Escrow Receipts"), such Escrow
Receipts to be issued under the corresponding Escrow Agreements,

                 (i)      an executed copy of each of the three Deposit
Agreements,

                 (j)      the forms of Assignment and Assumption Agreement
attached to the Original Pass Through Trust Agreements (the "Form Assignment
and Assumption Agreements"; the Pass Through Trust Agreements, the Note
Purchase Agreement, the Pass Through Certificates, the Intercreditor Agreement,
the Liquidity Facilities, the Escrow Agreements,

                                      -3-

the Escrow Receipts, the Deposit Agreements and the Assignment and Assumption
Agreements (as defined below) are referred to herein collectively as the "Pass
Through Trust Documents"),

                 (k)      the forms of "Leased Aircraft Indenture", "Leased
Aircraft Participation Agreement", "Lease", "Owned Aircraft Indenture", and
"Owned Aircraft Participation Agreement" attached to the Note Purchase
Agreement (collectively, the "Form Aircraft Financing Documents"),

                 (l)      an executed copy of the Registration Rights
Agreement,

                 (m)      the Final Memorandum dated January      , 1998 (the
"Final Memorandum") and

                 (n)      the documents delivered to you by Atlas at the
closing pursuant to the Placement Agreement, including copies of Atlas'
Certificate of Incorporation (the "Certificate of Incorporation") and By-Laws
certified by the Secretary of the State of Delaware and the Assistant Secretary
of Atlas, respectively.

                 We have considered such matters of law and fact, and relied
upon such certificates of officers of Atlas and public officials, corporate
records and other information furnished to us, including without limitation the
certificates and representations referred to below, as we have deemed
appropriate as a basis for the opinions set forth below.

                 In arriving at the opinion expressed below, we have assumed
the authenticity of all documents submitted to us as originals and the
conformity to the originals of all documents submitted to us copies. In
addition, we have (i) reviewed the representations and warranties set forth
therein, including without limitation the accuracy of the representations and
warranties set forth in Section 5(a) of each of the Deposit Agreements and
Section 5(i) of each of the Escrow Agreements, (ii) assumed that (A) each of
the Pass Through Trust Documents has been (or, in the case of the Assignment
and Assumption Agreements, will be) duly authorized, executed and delivered by
each party thereto (other than Atlas and (B) each party to the Pass Through
Trust Documents has the power and authority to enter into the Pass Through
Trust Documents and has satisfied (or, in the case of the Assignment and
Assumption Agreements, will satisfy) those legal requirements that are
applicable to it to the extent necessary to make such agreement or obligation
enforceable against it (except that the assumption set forth in this clause
(ii)(B) is not made as to Atlas regarding matters of the law of the State of
New York, applicable federal laws of the United States of America (other than
federal aviation laws and other federal laws relating to the operation or
maintenance of the Aircraft by Atlas) or the General Corporation Law of the
State of Delaware), and
<PAGE>   58
                                      -4-

that, except as specifically covered in the opinions expressed below, each of
the Pass Through Trust Documents is a valid, binding and enforceable obligation
of each party thereto, (iii) that the Pass Through Certificates and the Escrow
Receipts conform (and when executed and delivered by the parties thereto will
conform) as to the forms thereof that we have reviewed, (iv) that the Pass
Through Certificates and the Escrow Receipts will be duly executed,
authenticated and delivered, against payment therefor, all in accordance with
the terms of the Pass Through Trust Documents and the Escrow Agreements,
respectively, and of the Placement Agreement, and (v) that each Indenture,
Lease, Participation Agreement and Equipment Note conforms or will conform, as
the case may be, to the appropriate Form Aircraft Financing Document or, in the
case of Equipment Notes, to the forms thereof set forth in the relevant Form
Aircraft Financing Document.

                 Based on and subject to the foregoing, and to the other
assumptions, qualifications and limitations set forth herein, it is our opinion
that:

                 1.       Atlas is validly existing as a corporation in good
standing under the laws of the State of Delaware.

                 2.       Atlas has the corporate power (i) to own, lease and
operate its properties and conduct its business as described in the Final
Memorandum and (ii) to enter into each of the Pass Through Trust Documents and
the Placement Agreement and to perform its obligations thereunder.

                 3.       The execution and delivery by Atlas of each of the
Atlas Pass Through Trust Documents have been duly authorized by all necessary
corporate action of Atlas, and each of the Atlas Pass Through Trust Documents
has been duly executed and delivered by Atlas. Each of the Atlas Pass Through
Trust Documents (other than the Original Pass Through Trust Agreements, as to
which we express no opinion) is a valid and binding obligation of Atlas
enforceable against Atlas in accordance with its terms.

                 4.       The execution and delivery by Atlas of the Placement
Agreement and the Registration Rights Agreement has been duly authorized by all
necessary corporate action of Atlas, and each of the Placement Agreement and
the Registration Rights Agreement has been duly executed and delivered by
Atlas.

                 5.       Each of the Intercreditor Agreement, the Note
Purchase Agreement and the Escrow Agreements is a valid and binding obligation
of each Trustee that is a party thereto enforceable against each such Trustee
in accordance with its terms. Each of the Successor Pass Through Trust
Agreements is a valid and binding obligation of the applicable
<PAGE>   59
                                      -5-

Successor Trustee enforceable against the applicable Successor Trustee in
accordance with its terms. When executed and delivered in accordance with the
terms of the Original Pass Through Trust Agreements and the Successor Pass
Through Trust Agreements and in the form of the applicable Form Assignment and
Assumption Agreement, properly completed, assuming that all facts and
circumstances relevant to such matter are the same as is the case on the date
hereof, each of the assignment and assumption agreements contemplated under the
Original Pass Through Trust Agreements to be executed and delivered by the
Trustees and the Successor Trustees (collectively, the "Assignment and
Assumption Agreements") will be a valid and binding obligation of each of the
parties thereto enforceable against each of such parties in accordance with its
terms. When the Successor Pass Through Trust Agreements become effective
according to their terms, the applicable conditions precedent set forth in the
Original Pass Through Trust Agreements and Successor Pass Through Trust
Agreements have been satisfied and the related Assignment and Assumption
Agreement has been executed and delivered by each of the parties thereto,
assuming that all facts and circumstances relevant to such matter are the same
as is the case on the date hereof, each of the Pass Through Trust Certificates
lawfully and validly Outstanding (as such term is defined in the Original Pass
Through Trust Agreements) under the Original Pass Through Trust Agreements at
such time will be entitled to the benefits of such Successor Pass Through Trust
Agreements. Each of the Liquidity Facilities, the Intercreditor Agreement and
the Note Purchase Agreement is a legal, valid and binding obligation of the
Subordination Agent enforceable against the Subordination Agent in accordance
with its terms. Each of the Escrow Agreements, the Deposit Agreements and the
Note Purchase Agreement is a valid and binding obligation of each Escrow Agent
that is a party thereto enforceable against each such Escrow Agent in
accordance with its terms. The Escrow Receipts are validly issued and
outstanding and are entitled to the benefits of the applicable Escrow
Agreement. Each of the Escrow Agreement and the Note Purchase Agreement is a
valid and binding obligation of the Paying Agent that is a party thereto
enforceable against such Paying Agent in accordance with its terms.

                 6.       The statements set forth under the headings
"Description of the Certificates," "Description of the Deposit Agreements",
"Description of the Escrow Agents", "Description of the Liquidity Facilities,"
"Description of the Intercreditor Agreement" and "Description of the Equipment
Notes" in the Final Memorandum, insofar as such statements purport to summarize
certain provisions of the Pass Through Certificates, the Pass Through Trust
Agreements, the Deposit Agreements, the Escrow Agreements, the Escrow Receipts,
the Liquidity Facilities, the Intercreditor Agreement and the Form Aircraft
Financing Documents, provide a fair summary of such provisions. The statements
set forth under "ERISA Considerations" in the Final Memorandum, insofar as such
statements purport to summarize certain federal laws
<PAGE>   60
                                      -6-

of the United States, provide a fair summary of such laws. The statements set
forth under "Description of the Equipment Notes--Remedies" in the Final
Memorandum, insofar as such statements purport to summarize provisions of
Section 1110 of the U.S. Bankruptcy Code, provide a fair summary of such
provisions.

                 7.       While there is no authority addressing the
characterization of entities that are similar to the Trusts in all material
respects, each of the Original Trusts should be classified as a grantor trust
for U.S. federal income tax purposes. If, as may be the case, the Original
Trusts are not classified as grantor trusts, they will be classified as
partnerships for U.S. federal income tax purposes and will not be classified as
publicly traded partnerships taxable as corporations provided that at least 90%
of each such Original Trust's gross income for each taxable year of its
existence is "qualifying income" within the meaning of Section 7704(d) of the
Internal Revenue Code of 1986, as amended. Each of the Successor Trusts will be
classified as a grantor trust for U.S. federal income tax purposes. The
statements set forth under the heading "Certain U.S. Federal Income Tax
Consequences" in the Final Memorandum, insofar as such statements purport to
address the federal income tax laws of the United States, are accurate in all
material respects with respect to the matters discussed therein and constitute
a fair summary of the material U.S. federal income tax consequences of an
investment in the Pass Through Certificates (with attached Escrow Receipts).

                 8.       Atlas is not an "investment company" within the
meaning of the Investment Company Act of 1940, as amended (the "Investment
Company Act"). The Original Trusts created under the Original Pass Through
Trust Agreements are not required to be registered under the Investment Company
Act. As of the Successor Pass Through Trust Effective Date, assuming that all
facts and circumstances relevant to such matter are the same as is the case on
the date hereof, the Successor Trusts created under the Successor Pass Through
Trust Agreements will not be required to be registered under the Investment
Company Act.

                 9.       The issuance and sale of the Pass Through
Certificates to the Placement Agent pursuant to the Placement Agreement, the
issuance of the Escrow Receipts attached to Pass Through Certificates, the
valid authorization, execution and delivery of the Atlas Pass Through Trust
Documents by Atlas and the performance by Atlas of its respective obligations
under the Atlas Pass Through Trust Documents do not require Atlas to obtain or
effect any consent, approval, authorization, registration or qualification of
or with any governmental agency or body of the United States or of the State of
New York, except such as are required under the Securities Act of 1933, as
amended (the "Securities Act"), and the securities or blue sky laws of the
various states. Neither the execution and delivery by Atlas of the Atlas Pass
Through Trust Documents and the Placement Agreement nor the consummation
<PAGE>   61
                                      -7-

by Atlas of the transactions contemplated thereby to be consummated on the date
hereof violates (i) Atlas' Certificate of Incorporation or By-Laws or (ii) any
law or governmental rule or regulation known to us to be applicable to, or
binding on, Atlas. Assuming that all facts and circumstances relevant to such
matter are the same on the Successor Pass Through Trust Effective Date as is
the case on the date hereof, neither the execution and delivery of the
Assignment and Assumption Agreements on such Successor Pass Through Trust
Effective Date in accordance with the terms of the Original Pass Through Trust
Agreements and the Successor Pass Through Trust Agreements and in the form of
the applicable Form Assignment and Assumption Agreement, nor the consummation
by the parties thereto of the transactions contemplated to be consummated
thereunder on such Successor Pass Through Effective Date, will violate any law
or governmental rule or regulation known to us to be applicable to the
transactions contemplated by the Assignment and Assumption Agreements.

                 10.      Each of the Escrow Agreements creates a valid escrow
under New York law and a valid equitable interest in the escrowed property in
favor of the corresponding Trustee. Neither a New York court nor a United
States federal court applying New York law or the U.S. Bankruptcy Code, if
properly presented with the issue and after having properly considered such
issue, would permit any holder of an Escrow Receipt to terminate the related
Escrow Agreement, except in accordance with its terms.

                 11.      So long as an Escrow Agreement has not been
terminated, creditors of any person that is a holder of an Escrow Receipt
thereunder or holders of a lien against the assets of any such person, such as
trustees, receivers or liquidators (whether or not any insolvency proceeding
has been commenced) (collectively, the "Creditors"), may acquire valid claims
and liens, as to the Deposits established thereunder and as to the related
Deposit Agreement and Escrow Agreement, only against the rights of the holder
of such Escrow Receipt under such Escrow Agreement, and do not have, and may
not through the enforcement of such Creditors' rights acquire, any greater
right than the holder of such Escrow Receipt with respect to such Deposits,
Deposit Agreement or Escrow Agreement.

                 12.      No creditor of Atlas or any of its subsidiaries, and
no holder of a lien against the assets of any such person, such as trustees,
receivers or liquidators (whether or not any insolvency proceeding has been
commenced), may acquire valid claims or liens as to the Deposits and the
related Deposit Agreements and Escrow Agreements. Payment by the Depositary of
interest, Purchase Withdrawal and Final Withdrawal amounts pursuant to Section
2.02 and 2.03, as the case may be, of the Deposit Agreements, made in
accordance with the terms of the Deposit Agreements, will not constitute
preferential payments under Section 547 of the Bankruptcy Code recoverable
under Section 550 of the Bankruptcy Code should Atlas or any of its
subsidiaries become a debtor in proceedings under the Bankruptcy Code.

                                      -8-


                 13.      No registration under the Securities Act of the Pass
Through Certificates is required in connection with the sale of the Pass
Through Certificates to the Placement Agents as contemplated by the Placement
Agreement and the Final Memorandum or in connection with the initial resale of
the Pass Through Certificates by the Placement Agents in accordance with
Section 2 of the Placement Agreement, and prior to the commencement of the
Exchange Offer (as defined in the Registration Rights Agreement) or the
effectiveness of the Shelf Registration Statement (as defined in the
Registration Rights Agreement), the Pass Through Trust Agreements are not
required to be qualified under the TIA, in each case assuming (i)(A) that the
purchasers who buy such Pass Through Certificates in the initial resale thereof
are qualified institutional buyers as defined in Rule 144A promulgated under
the Act ("QIBs"), or other investors that are institutional "accredited
investors" as that term is defined in Rule 501(A)(1), (2), (3) or (7) under the
Act or (B) that the offer or sale of the Pass Through Certificates is made in
an offshore transaction as defined in Regulation S under the Act, (ii) the
accuracy of the Placement Agents' representations in Section 6 of the Placement
Agreement and those of Atlas contained in the Placement Agreement regarding the
absence of a general solicitation in connection with the sale of such Pass
Through Certificates to the Placement Agent and the initial resale thereof and
(iii) the due performance by the Placement Agents of the agreements set forth
in Section 6 of the Placement Agreement.

                 The foregoing opinions are subject to the following
assumptions, qualifications and limitations:

                 (a)      The opinions in paragraphs 3 and 5 above are subject
to (i) bankruptcy, insolvency, fraudulent transfer, fraudulent conveyance or
other similar laws affecting the rights or remedies of creditors generally,
(ii) general principles of equity including, without limitation, laches and
estoppel as equitable defenses and concepts of materiality, reasonableness,
good faith and fair dealing (regardless of whether enforceability is considered
or applied in a proceeding in equity or at law) and considerations of
impracticability or impossibility of performance, and defenses based upon
unconscionability of otherwise enforceable obligations in the context of the
factual circumstances under with enforcement thereof is sought, (iii) the
qualification that the remedy of specific performance and injunctive and other
forms of equitable relief may be subject to equitable defenses and to the
discretion of the court before which any proceeding therefor may be brought and
(iv) in the case of the Successor Pass Through Trust Agreements, the delayed
effectiveness thereof in accordance with their respective terms. The opinions
in paragraphs 10, 11 and 12 above are subject to (i) fraudulent transfer or
fraudulent conveyance laws, (ii)
<PAGE>   63
                                      -9-

general principles of equity including, without limitation, laches and estoppel
as equitable defenses and concepts of materiality, reasonableness, good faith
and fair dealing (regardless of whether enforceability is considered or applied
in a proceeding in equity or at law) and considerations of impracticability or
impossibility of performance, and defenses based upon unconscionability of
otherwise enforceable obligations in the context of the factual circumstances
under which enforcement thereof is sought and (iii) the qualifications that the
remedy of specific performance and injunctive and other forms of equitable
relief may be subject to equitable defenses and to the discretion of the court
before which any proceeding therefor may be brought.

                 (b)      We express no opinion as to Section 7.11(a)(ii) of
the Liquidity Facilities or Section 10.11(a)(ii) of the Intercreditor Agreement
whereby the parties to such agreements waive any objections to the laying of
venue in the courts of the State of New York and the courts of the United
States of America for the Southern District of New York (and we note that such
matters may be raised by such courts). We express no opinion as the
enforceability of any provision contained in any of the Pass Through Trust
Documents (i) that purports to establish or may be construed to establish
evidentiary standards, (ii) as such provision relates to the jurisdiction of
federal courts or (iii) providing for late payment charges but only to the
extent such provision is deemed to constitute a penalty or liquidated damages
provision. Under certain circumstances the requirement that the provisions of a
Pass Through Trust Document may be modified or waived only in writing or only
in a specific instance and provisions to the effect that failure or delay in
exercising any right, remedy, power and/or privilege will not impair or waive
such right, remedy, power and/or privilege may be unenforceable to the extent
that an oral agreement has been effected on a course of dealing has occurred
modifying such provisions. A court may modify or limit contractual agreements
regarding attorneys' fees.

                 (c)      Provisions of any Pass Through Trust Document which
permit any person to take action or make determinations, or to benefit from
indemnities, contribution agreements or similar undertakings, or waivers,
exculpatory provisions or similar provisions, may be subject to limitations
imposed by law or by public policy considerations.

                 (d)      Insofar as the foregoing opinions relate to the valid
existence and good standing of Atlas, they are based solely on a certificate of
good standing received from the Secretary of State of the State of Delaware.

                 (e)      In stating the opinions set forth in paragraphs 10
and 11, we have assumed that each holder of an Escrow Receipt is and will
<PAGE>   64
                                      -10-

at all relevant times be an entity of a type eligible for relief under the
Federal Bankruptcy Code as provided in Section 109 thereof.

                 (f)      The foregoing opinions are limited to the law of the
State of New York, the federal law of the United States of America and the
General Corporation Law of the State of Delaware, in each case as in effect on
the date hereof, except that we express no opinion with respect to (i) the
laws, regulations or ordinances of any county, town or municipality or
governmental subdivision or agency thereof, (ii)(x) state securities or blue
sky laws (y) except as set forth in paragraph 8 above, the Investment Company
Act, or (z) except as set forth in paragraph 9 above, federal securities laws
other than the Investment Company Act, including without limitation the
Securities Act and the Trust Indenture Act, (iii) any federal (except as set
forth in paragraph 7 above) or state tax, antitrust or fraudulent transfer or
conveyance laws, (iv) except as set forth in the penultimate sentence of
paragraph 6 above, the Employee Retirement Income Security Act of 1974, as
amended, or (v) federal aviation laws and other federal laws relating to the
operation and maintenance of the Aircraft by Atlas. In addition, our opinions
are based upon a review of those laws, statutes, rules and regulations which,
in our experience, are normally applicable to transactions.

                 We have participated in conferences with officers and other
representatives of Atlas, representatives of the independent public accountants
for Atlas, representatives of the Placement Agents and counsel for the
Placement Agents, at which the contents of the Final Memorandum and related
matters were discussed. Although we are not passing upon and do not assume any
responsibility for the accuracy, completeness or fairness of the statements
contained in the Final Memorandum, on the basis of the foregoing (relying as to
materiality to a large extent on discussions with and representations and
opinions of officers and other representatives of Atlas) no facts have come to
our attention which lead us to believe that the Final Memorandum (except for
the financial statements and other financial or statistical data included
therein or omitted therefrom, as to which we need express no opinion), on the
date thereof or at the Closing Date, contained an untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements contained therein, in the light of the
circumstances under which they were made, not misleading.

                 We are furnishing this opinion letter to you solely for your
benefit. This opinion letter is not to be used, circulated or otherwise
referred to for any other purpose whatsoever without in each instance our prior
written consent. This opinion letter speaks only as of the date hereof and we
disclaim any obligation to advise you of changes of law or fact that occur
after the date hereof.

                               Very truly yours,

Form of Opinion of David Brictson, In-House Legal Counsel to the Company
<PAGE>   66
                               [ATLAS LETTERHEAD]



                                                                February 9, 1998

To Each of the Persons Listed 
  on Schedule A Attached Hereto

Ladies and Gentlemen:

     I am the Legal Counsel of Atlas Air, Inc., a Delaware corporation
("Atlas").  In such capacity, I and persons on my legal staff have acted as
counsel to Atlas in connection with the transactions contemplated by the
Placement Agreement dated January 27, 1998 among Morgan Stanley & Co.
Incorporated, BT Alex. Brown Incorporated, Donaldson, Lufkin & Jenrette
Securities Corporation, and Goldman Sachs & Co. (collectively, the "Placement
Agents") and Atlas (the "Placement Agreement"). Capitalized terms used but not
defined herein shall have the meanings ascribed to them in the Placement
Agreement or, if not defined therein, the Intercreditor Agreement (as defined
below).  This opinion is furnished pursuant to Section 3(e) of the Placement
Agreement.

     In arriving at the opinions expressed below, I or members of my legal
staff have reviewed the following documents, each of which is dated as of the

     (b) an executed copy of the Note Purchase Agreement,

     (c) executed copies of the three Original Pass Through Trust Agreements,
         dated as of February 9, 1998 between Atlas and Wilmington Trust

         individually as a "Successor Pass Through Trust Agreement" and
         collectively as the "Successor Pass Through Trust Agreements", and the

     (n) the documents delivered to you by Atlas at the closing pursuant to the
         Placement Agreement, including copies of Atlas' Certificate of
         Incorporation (the "Certificate of Incorporation") and By-Laws
         certified by the Secretary of State of the State of Delaware and the
         Assistant Secretary of Atlas, respectively.

In addition, I or members of my legal staff have reviewed the originals or
copies certified or otherwise identified to my or their satisfaction of all
such corporate records of Atlas and its Subsidiaries (as defined below) and
such other instruments and other certificates of public officials, officers and
representatives of Atlas and such other persons, and I or members of
<PAGE>   69



                                      -4-

my legal staff have made such investigations of law, as I deemed appropriate as
a basis for the opinions expressed below.

    In arriving at the opinions expressed below, I and members of my legal
staff have assumed the authenticity of all documents submitted to us as
originals and the conformity to the originals of all documents submitted to us
as copies. In addition, I and members of my legal staff have assumed and have
not verified the accuracy as to factual matters of each document I or they have
reviewed including, without limitation, the accuracy of the representations and
warranties of Atlas in the Placement Agreement. As used herein, the phrase "to
my knowledge" shall mean to my actual knowledge after reasonable investigation,
but shall not be interpreted to impute to me knowledge of others.

    Based on the foregoing, and subject to the further assumptions,
qualifications and limitations set forth below, it is my opinion that:

    1.  Each of Atlas One, Inc., Atlas Freighter Leasing, Inc., Atlas Freighter
Leasing II, Inc., Atlas Air Services Limited, LHC Properties, Inc., Genessee
Insurance Company, Ltd. and Atlas Freightlease, Inc. (together, the
"Subsidiaries") and Atlas has been duly incorporated and is an existing
corporation in good standing under the laws of the jurisdiction of its
incorporation, with corporate power to own, lease and operate its properties
and conduct its business as described in the Offering Memorandum. Each of Atlas
and its Subsidiaries is duly qualified to do business as a foreign corporation
in good standing in all other jurisdictions in the United States in which its
ownership or lease of property or the conduct of its business requires such
qualification, except where the failure to be so qualified would not have an
Atlas Material Adverse Effect.

    2.  To my knowledge, except as disclosed in the Offering Memorandum, there
is no action, suit or proceeding before or by any governmental agency or body
or court, domestic or foreign, now pending against Atlas or any of the
Subsidiaries or any of their respective properties that will have an Atlas
Material Adverse Effect or will have a material adverse effect on the ability
of Atlas to perform its obligations under any of the Pass Through Trust
Agreements or the Note Purchase Agreement (the Pass Through Trust Agreements
and the Note Purchase Agreement are referred to collectively as the "Atlas Pass
Through Trust Documents").

                                      -5-


          3.   Atlas is a "citizen of the United States" within the meaning of
Section 40102(a)(15) of Title 49 of the United States Code, as amended, holding
an air carrier operating certificate issued by the Secretary of Transportation
pursuant to Chapter 447 of Title 49 of the United States Code, as amended, for
aircraft capable of carrying 10 or more individuals or 6,000 pounds or more of
cargo.

          4.   The execution, delivery and performance by Atlas of the Atlas
Pass Through Trust Documents, and the consummation by Atlas of the transactions
contemplated by such documents, will not result in any violation of the
provisions of the Certificate of Incorporation or By-Laws of Atlas or, to my
acknowledge, any applicable law, administrative regulation or any
administrative or court decree, nor does any such action, to my knowledge,
constitute a breach of, or default under, or (except as contemplated therein)
result in the creation or imposition of any lien, charge or encumbrance upon
any assets of Atlas or any of the Subsidiaries pursuant to, any material
contract, indenture, mortgage, loan agreement, note, lease or other instrument
to which Atlas or any of the Subsidiaries is a party or by which any of them
are bound or to which any of the assets of Atlas or any of the Subsidiaries is
subject.

          5.   The issuance and sale of the Pass Through Certificates to the
Placement Agents pursuant to the Placement Agreement, the issuance of the
Escrow Receipts attached to the Pass Through Certificates, the valid
authorization, execution and delivery of the Atlas Pass Through Trust Documents
by Atlas and the performance by Atlas of its obligations under the Atlas Pass
Through Trust Documents do not require Atlas to obtain or effect any consent,
approval, authorization, registration or qualification of or with any
governmental agency or body of the United States or the State of Colorado,
except such as may be required under federal or state securities or blue sky
laws.

          6.   To my knowledge, except as disclosed in the Offering Memorandum,
there is no event of default under any material agreement or instrument under
which indebtedness of Atlas is outstanding or by which it is bound or any of
its properties is subject.

          7.   To my knowledge, there are no legal or governmental proceedings
pending or threatened against Atlas or any Subsidiary other than those
disclosed in the Offering Memorandum or those which individually (or in the
aggregate in the case of any class of related lawsuits) could not reasonably be
expected to have a Atlas Material Adverse Effect.

         Insofar as the foregoing opinions relate to the valid existence and
good standing of Atlas and the Subsidiaries, they are based solely on
certificates of good standing received from the appropriate officials of the
respective jurisdictions of incorporation. Insofar as the foregoing opinions
relate to qualification to do business of Atlas and the Subsidiaries, they are
based solely on certificates of foreign qualification received from the
applicable Secretary of State's office.

         The foregoing opinions are limited to the federal law of the United
States of America, the General Corporation Law of the State of Delaware and the
law of the State of Colorado, in each case as in effect on the date hereof,
except that I express no opinion with respect to (i) the laws, regulations or
ordinances of any county, town or municipality or governmental subdivision or
agency thereof, (ii) (x) state securities or blue sky laws and (y) federal
securities laws, including without limitation the Securities Act, the Securities
Exchange Act of 1934, as amended, the Trust Indenture Act of 1939, as amended,
and the Investment Company Act of 1940, as amended, (iii) any federal or state
tax, antitrust or fraudulent transfer or conveyance laws (iv) the Employee
Retirement Income Security Act of 1974, as amended, or (v) federal aviation
laws, or any other federal laws relating to the operation and maintenance by
Atlas of the Aircraft. In addition, my opinions are based upon a review of those
laws, statutes, rules and regulations which, in my experience, are normally
applicable to transactions of the type contemplated by the Pass Through Trust
Documents.

         I am furnishing this opinion letter to you solely for your benefit in
connection with the transactions described above. This opinion letter is not to
be used, circulated, quoted or otherwise referred to by any other person or for
any other purpose. This opinion letter speaks only as of the date hereof and I
disclaim any obligation to advise you of changes of law or fact that occur after
the date hereof.

     Re: Atlas Air Pass Through Certificates, Series 1998 1

Ladies and Gentlemen:

     We have acted as counsel to Wilmington Trust Company, a Delaware banking
corporation (in its individual capacity, "Wilmington Trust", in its capacity as
Mortgagee, Subordination Agent, and Pass Through Trustee, as the case be,
the "Trustee"), in connection with the transactions contemplated by the Pass
Through Trust Agreements between Atlas Air, Inc. ("Atlas") and Wilmington
Trust, as Trustee, (the "Pass Through Trust Agreements"), relating to
Atlas Air Pass Through Trust, 1998-1A-O, Atlas Air Pass Through Trust
1998-1B-O, and Atlas Air Pass Through Trust 1998-1C-O (collectively, the
"Trusts"), each dated as of February 9, 1998.  This opinion is furnished at
your request in connection with the Pass Through Certificates being issued
today.  Capitalized terms used herein and not otherwise defined are used as
defined in the Pass Through Trust Agreements, except that reference herein to
any documents shall mean such documents as in effect as of the date hereof.

     We have examined executed counterparts of the following documents:

          (a)  the Pass Through Trust Agreements;
          
          (b)  the Intercreditor Agreement;
<PAGE>   74

          (c)  each of the Liquidity Facilities;

          (d)  the Registration Rights Agreement

          (e)  the Indenture (the documents described in items (a) through (e) 
               are collectively referred to herein as the "Transaction 
               Documents"); and

          (f)  the Certificates being issued today in definitive form by the
               Trusts "Certificates".

     We also have examined and relied on originals or copies of such other
documents and such corporate records, certificates and other statements of
governmental officials and corporate officers and other representatives of the
corporations or entities referred to herein as we have deemed necessary or
appropriate for the purposes of this opinion. Moreover, as to certain facts
material to the opinions expressed herein, we also have relied upon the
representations and warranties contained in the certificates and other
documents referred to in this paragraph.

     Based upon the foregoing and upon an examination of such questions of law
as we have considered necessary or appropriate, and subject to the assumptions,
exceptions and qualifications set forth below, we advise you that, in our
opinion:

   1. Wilmington Trust is a banking corporation duly organized and validly
existing in good standing under the laws of the State of Delaware, and has the
corporate power and authority to execute, deliver and perform, in its
individual capacity, or as Trustee, as the case may be, the Transaction
Documents, and the Certificates. Wilmington Trust is a "citizen of the United
States" as defined in 49 U.S.C. Section 40102.

  
   2. Each of the Transaction Documents has been duly authorized, executed and
delivered by Wilmington Trust in its individual capacity, or as Trustee, as the
case may be, and constitutes the legal, valid and binding obligation of
Wilmington Trust in its individual capacity, or as Trustee, as the case may
be, enforceable against Wilmington Trust in its individual capacity, or as
Trustee, as the case may be, in accordance with its terms.


   3. The Pass Through Trust Agreements constitute the legal, valid and binding
obligations of Atlas, enforceable against Atlas in accordance with their terms.

   4. Wilmington Trust, solely in its capacity as Trustee, has duly authorized, 
issued, executed and delivered the Certificates to the holder thereof
pursuant to the 
<PAGE>   75
To each of the Parties Listed
on Schedule A Attached Hereto
February 9, 1998
Page 3


terms and provisions of the Pass Through Trust Agreements; the Certificate are
duly authorized, legal, valid and binding obligations of the Trusts,
enforceable against the Trusts in accordance with their terms and the terms of
the Pass Through Agreements and are entitled to the benefits of the Pass
Through Trust Agreements; when issued in exchange for the certificates pursuant
to the Registration rights Agreement and authenticated pursuant to the Pass
Through Trust Agreements, the Exchange Certificates will be duly authorized,
legal, valid and binding obligations of the Trusts, enforceable against the
Trusts in accordance with their terms and the terms of the Pass Through Trust
Agreements and will be entitled to the benefits of the Pass Through Trust
Agreements.

     5.   No authorization, consent or approval of, notice to or filing with,
or the taking of any other action in respect of, any governmental authority or
agency of the United States or the State of Delaware governing the banking or
trust powers of Wilmington Trust is required for the execution, delivery or
performance by Wilmington Trust in its individual capacity, or as Trustee, as
the case may be, of the Transaction documents or the Certificates.

     6.   Neither the execution, delivery or performance by Wilmington Trust in
its individual capacity, or as Trustee, as the case may be, of the Transaction
Documents or the Certificates, nor compliance with the terms and provisions
thereof, conflicts with the charter or bylaws of Wilmington Trust or results in
a breach or violation of any of the terms, conditions or provisions of any law,
governmental rule or regulation of the United States or the State of Delaware
governing the banking or trust powers of Wilmington Trust or, to our knowledge,
any order, writ, injunction or decree of any court or governmental authority
against Wilmington Trust or by which it or any of its properties is bound or,
to our knowledge, any indenture, mortgage, contract or other agreement or
instrument to which Wilmington Trust is a party or by which it or any of its
properties is bound, or constitutes a default thereunder.

     7.   Assuming that the Trusts will not be taxable as corporations, but,
rather, will be classified as grantor trusts under subpart E, Part I of
Subchapter J of the United States Internal Revenue Code of 1986 (the "Code"),
as amended, or as partnerships under Subchapter K of the Code, and assuming (a)
that the assets of the Trusts will be treated as held for investment purposes
as provided in each Pass Through Trust Agreement and (b) that the acquisition,
management and disposition of the assets of the Trusts (if the assets were held
by a Certificateholder directly) would not constitute an integral part of the
regular trade or business of such Certificateholder (other than the trade or
business of investing), (i) the   
<PAGE>   76
To Each of the Parties Listed
on Schedule A Attached Hereto
February 9, 1998
Page 4

Trusts will not be subject to any tax (including, without limitation, net or
gross income, tangible or intangible property, net worth, capital, franchise or
doing business tax), fee or other governmental charge under the laws of the
State of Delaware or any political subdivision thereof and (ii)
Certificateholders that are not residents of or otherwise subject to tax in
Delaware will not be subject to any tax (including, without limitation, net or
gross income, tangible or intangible property, net worth, capital, franchise or
doing business tax), fee or other governmental charge under the laws of the
State of Delaware or any political subdivision thereof as a result of
purchasing, holding (including receiving payments with respect to) or selling a
Certificate.

     8. To our knowledge, there are no proceedings pending or threatened
against or affecting Wilmington Trust in any court or before any governmental
authority, agency, arbitration board or tribunal which, if adversely
determined, individually or in the aggregate, would materially and adversely
affect the Trusts or question the right, power and authority of Wilmington
Trust in its individual capacity, or as Trustee, as the case may be, to enter
into or perform its obligations under the Transaction Documents or which would
call into question or challenge the validity of any of the Transaction
Documents or the enforceability thereof.

     9. Each of the Equipment Notes (as defined in the Trust Indenture) to be
delivered to and registered in the name of the Subordination Agent pursuant to
the Intercreditor Agreement will be held by the Subordination Agent in trust as
trustee for the Trusts under the Pass Through Trust Agreements on behalf of the
Certificateholder of the Trusts.

        The foregoing opinions are subject to the following assumptions,
exceptions and qualifications:

     1. We are admitted to practice law in the State of Delaware and do not
hold ourselves out as being experts on the law of any other jurisdiction. The
foregoing opinions are limited to the laws of the State of Delaware and the
federal laws of the United States of America governing the banking and trust
powers of Wilmington Trust (except that we express no opinion with respect to
(i) federal securities laws, including, without limitation, the Securities Act
of 1933, as amended, the Trust Indenture Act of 1939, as amended, and the
Investment Company Act of 1940, as amended, or (ii) state securities or blue
sky laws). Insofar as the foregoing opinions relate to the validity and
enforceability of the Transaction Documents expressed to be governed by the
laws of the State of New York, we have assumed that each such document is
legal, valid, binding and enforceable in accordance with its terms under such
laws (as to which we express no opinion).
<PAGE>   77

To Each of the Parties Listed

    B.  The foregoing opinions regarding enforceability are subject to (i)
applicable bankruptcy, insolvency, moratorium, receivership, reorganization,
fraudulent conveyance and similar laws relating to or affecting the rights and
remedies of creditors generally, and (ii) principles of equity (regardless of
whether considered and applied in a proceeding in equity or at law).

    C.  We have assumed the due authorization, execution and delivery by each
of the parties thereto (other than Wilmington Trust in its individual capacity,
or as Trustee, as the case may be) of the Transaction Documents, that each of
such parties has the full power, authority and legal right to execute, deliver
and perform each such document.

    D.  We have assumed that all signatures (other than those of Wilmington
Trust in its individual capacity, or as Trustee, as the case may be) on
documents examined by us are genuine, that all documents submitted to us as
originals are authentic, and that all documents submitted to us as copies or
specimens conform with the originals, which facts were have not independently
verified.

    E.  We have not participated in the  preparation of any offering
materials with respect to the Certificates and assume no responsibility for
their contents.

    This opinion may be relied upon by you in connection with the matters set
forth herein. Without our prior written consent, this opinion may be not be
furnished or quoted to, or relied upon by, any other person or entity for any
purpose.

                                Very truly yours,

RE:     ATLAS AIR, INC. PASS THROUGH CERTIFICATES, SERIES 1998-1

Ladies and Gentlemen:

    We have acted as special counsel to ABN AMRO Bank N.V., Chicago Branch
("ABN AMRO") in connection with the transactions contemplated by that certain
Revolving Credit Agreement (1998-1A)(the "Credit Agreement"), dated as of
________ ____, 1998, by and between Wilmington Trust Company ("WTC"), not in
its individual capacity except as expressly provided therein, but solely as
Subordination Agent under the Intercreditor Agreement (as defined below), as
agent and trustee for the Atlas Airlines Pass Through trust 199_ -1A (the
"Trust"), as Borrower and ABN AMRO, as Liquidity Provider; and the
Intercreditor Agreement dated as of __________ ____, 1998 (the "Intercreditor
Agreement") by and among WTC, as Trustee under the Trust, ABN AMRO, as Class A
Liquidity Provider, Morgan Stanley & Co. Incorporated, as Class B Liquidity
Provider and Class C Liquidity Provider and WTC, as Subordination Agent and
Trustee (the Credit Agreement and the Intercreditor Agreement are hereinafter
collectively referred to as the "Liquidity Documents").

    Except as otherwise noted herein, all capitalized terms used herein shall
have the respective defined meanings set forth in the Credit Agreement.

    In connection with our opinion herein, we have (i) examined executed
counterparts of the Liquidity Documents, (ii) relied without independent
investigation or verification, upon the representations and warranties as to
factual matters contained in each of the Operative Agreements and upon
originals or copies, certified or otherwise identified to our satisfaction, of
such corporate records, documents and other instruments as we have deemed
relevant to the rendering of this opinion, and (iii) in such examination
assumed the genuineness of all signatures, the authenticity of all documents
submitted to us as originals and the conformity with the originals of all
documents submitted to us as copies.
<PAGE>   81
VEDDER PRICE



          Based upon and subject to the foregoing, it is our opinion that:

     1.   Each of the Liquidity Documents constitutes the legal, valid and
binding obligation of each of the parties thereto enforceable against such
parties in accordance with its terms, except as such enforceability is limited
by (i) bankruptcy, receivership, conservatorship, insolvency, fraudulent
transfer, liquidation, reorganization, moratorium or other laws affecting
creditors' rights and remedies generally from time to time in effect as the
same may be applied in the event of the bankruptcy, receivership,
conservatorship, insolvency, moratorium, liquidation, reorganization or similar
situation of any such party, or other similar occurrence with respect to any
such party or by laws affecting the rights of creditors of depository
institutions, (ii) the possible judicial application of foreign laws or
governmental action affecting creditors' rights generally, (iii) general
principles of equity (regardless of whether such enforceability is considered
in a proceeding in equity or at law), public policy and applicable law relating
to fiduciary duties, and (iv) any implied covenant of good faith and fair 
dealing.

     2.   ABN AMRO Bank N.V. is licensed by the Office of Banks and Real Estate
of the State of Illinois to maintain its branch at 135 LaSalle Street, Chicago,
Illinois (the "Branch"), in accordance with the banking law of the State of
Illinois and the Branch has the full power, authority and legal right to execute
and deliver the Liquidity Documents.

     3.   The execution, delivery and performance by ABN AMRO of the Liquidity
Documents, and the consummation of the transactions contemplated therein do not
violate any banking law, or any governmental rule or regulation relating 
thereto, of the United States of America, the State of Illinois or the State of
New York.

     4.   No authorization, consent, approval or other action by, and no notice
to or filing with, any banking authority or regulatory body of the United States
of America, the State of Illinois or the State of New York is required for the
due execution, delivery and performance by ABN AMRO of the Liquidity Documents 
other than administrative and ministerial filings which ABN AMRO is obligated to
make in the ordinary course of its business (which filings we have assumed have
been and will continue to be made in a timely manner).

     5.   The payment obligations of ABN AMRO under the Liquidity Documents
constitute unsecured and unsubordinated obligations of ABN AMRO.  

          No opinion is given herein as to (i) the availability of specific
performance or equitable relief of any kind or (ii) any federal or state
securities laws.

          In rendering the opinions set forth above, we have assumed that each
of the parties to the Liquidity Documents has the full power, authority and
legal right to enter into the Liquidity Documents and that the Liquidity
Documents have been duly authorized, executed and delivered by each of such
parties.
<PAGE>   82
VEDDER PRICE   

     We note that the operations of ABN AMRO are subject to the laws and
regulations of the State of Illinois, including the laws and regulations
governing bank deposits and collections and in the event of a conflict between
Illinois law and New York law regarding bank deposits and collections, Illinois
law would prevail.

     We further express no opinion as to the validity, binding effect or
enforceability of (i) purported waivers of any statutory or other rights, court
rules or defenses to obligations or consents to any actions where such waivers
or consents (A) are against public policy or (B) constitute waivers of rights
or consents to actions which by law, regulation or judicial decision may not
otherwise be waived or given, (ii) provisions indemnifying any person against,
or relieving any person of liability for, its own negligent or wrongful acts or
in any other circumstances where enforcement of such provisions would be against
public policy or limited or prohibited by applicable law, (iii) any provisions
which purport to authorize or permit any person to act in a manner which is
determined not to be in good faith or commercially reasonable or any provisions
which purport to waive any rights in respect of such acts, (iv) any provisions
which purport to authorize or permit any person to exercise any right or remedy
upon any nonmaterial breach or default, (v) any forum selection provision, (vi)
any powers of attorney to the extent that they purport to grant rights and
powers that may not be granted under applicable law, (vii) any right or
obligation to the extent that the same may be varied by course of dealing or
performance, or (viii) any provision that is subject to any mutual mistake of
fact or misunderstanding, fraud, duress or undue influence.

     This opinion is rendered to you for your benefit and may not be relied upon
by any other person, or by you for any other purpose, without our express
written consent.

     We do not express herein any opinion as to any matters governed by any law
other than the laws of the State of New York, the State of Illinois and the
Federal law of the United States. This opinion is given as of the date hereof
and we assume no obligation to advise you of any change which may hereafter be
brought to our attention.

Dear Sirs,



                      Atlas Air Pass Through Certificates
                                 Series 1998-1


We have acted as Dutch legal counsel to ABN AMRO Bank N.V. ("ABN AMRO"), acting
through its Chicago Branch, in connection with the revolving credit agreement
1998-1 dated as of [* January 1998 (the "Revolving Credit Agreement") by and
between [SUBORDINATION AGENT]("[*]") as Subordination Agent, as agent and as
trustee for Atlas Air Pass Through Trust 1998-1A, 1998-1B and 1998-1C (the

AMRO, Chicago Branch as Class A Liquidity Provider and [*] as Subordination
Agent and Trustee (the Revolving Credit Agreement and the Intercreditor
Agreement are hereinafter collectively referred to as the "Liquidity
Documents"). This opinion is being furnished at your specific request. In such
capacity, we have examined the following documents, as well as such other
documents and instruments as we have deemed necessary or advisable for the
purposes of this opinion:

(a)     [a draft of the Revolving Credit Agreement (1998-1) dated [*]] and a
        draft of the Intercreditor Agreement sent to us by fax of 12 January 
        1998;
<PAGE>   85
                                      -2-

(b)  a copy of the articles of association (statuten) of ABN AMRO as they stand
     on the date hereof since their latest amendment dated 21 September 1991,
     being the currently effective articles of association according to the
     extract referred to in (c) below (the "Articles of Association"); and

(c)  a copy of an official summary extract (beperkt uittreksel) dated 19
     December 1997 from the Commercial Register of the Chamber of Commerce of
     Amsterdam relating to the registration of ABN AMRO under number 332587 and
     confirmed to us by the Chamber of Commerce of Amsterdam by telephone on the
     date hereof to have remained unaltered since such date.

All capitalized terms not otherwise defined herein shall have the meaning set
forth in the Liquidity Documents.

Based upon the foregoing, we are of the opinion (limited in all respects to the
laws of The Netherlands) that:

1.   ABN AMRO is duly registered with the Commercial Register of the Amsterdam
     Chamber of Commerce as (i) a public company with limited liability
     (naamloze vennootschap), (ii) incorporated on 29 March 1824 and (iii)
     validly existing under the laws of The Netherlands and has the corporate
     power under the laws of The Netherlands to enter into the Liquidity
     Documents and to perform its obligations thereunder through its Chicago
     Branch.

2.   The execution, delivery and performance of the Liquidity Documents by the
     Chicago Branch of ABN AMRO have been duly authorised by all necessary
     corporate action on the part of ABN AMRO and do not contravene any
     provision of applicable law or regulation in The Netherlands or of the
     Articles of Association and no further authorisation by or any corporate
     action of ABN AMRO is required in connection with the execution, delivery
     and performance by it of the Liquidity Documents.

3.   Assuming the Liquidity Documents constitute legal, valid and binding
     obligations under the laws of the State of New York, and assuming due
     authorisation, execution and delivery thereof by all other parties to such
     Liquidity Documents, the Liquidity Documents, when executed and delivered
     by [*] and [*] of ABN AMRO's Chicago Branch, will constitute legal, valid
     and binding obligations of ABN AMRO enforceable against ABN AMRO in
     accordance with their terms, except as such enforceability may be limited
     by bankruptcy, insolvency, liquidation, reorganisation, moratorium or other
     similar laws affecting the rights of creditors against ABN AMRO generally,
     as the same may be applied in the event of bankruptcy, insolvency,
     liquidation or reorganisation of, or other similar occurrence with respect
     to, ABN AMRO or in the event of a moratorium or similar occurrence
     affecting ABN AMRO, and subject to the provisions of Chapter X of the Act
     on the Supervision of the Credit System 1992 (Wet Toezicht Kredietwezen
     1992) regarding emergency measures for credit institutions in The
     Netherlands.
<PAGE>   86
                                      -3-

4.   No consent or approval of any governmental authority in The Netherlands is
     required as a condition to the enforceability of ABN AMRO's obligations
     under the Liquidity Documents.

5    The courts of The Netherlands will observe and give affect to the choice of
     the laws of the State of New York as the laws governing the Liquidity 
     Documents in any proceedings in relation thereto on the basis and within
     the scope of and subject to the limitations imposed by the 1980 Rome
     Convention on the Law Applicable to Contractual Obligations (the "Rome     
     Convention").

     With the express reservation that as Dutch lawyers we are not qualified to
     assess the exact meaning and consequences of the terms of the Liquidity
     Documents under the laws of the State of New York, on the face of such
     document we are not aware of any provision that is likely to be manifestly
     incompatible with Netherlands' public policy (a limitation on the chosen
     law arising under article 16 Rome Convention) or that is likely to give
     rise to situations where mandatory rules of Netherlands' law will prevail
     over the chosen law of such document (a limitation on the chosen law
     arising under article 7 Rome Convention).  It should be noted that we are
     not aware of any published order, ruling or decision of a Netherlands'
     court, in which such court has given overriding effect to foreign
     mandatory rules pertaining to a law other than the chosen (or applicable)
     law or Netherlands' law (a limitation on the chosen law arising under
     article 7(1) Rome Convention) in commercial or financial litigation 
     brought before such courts.

6.   In the absence of an applicable treaty or convention providing for the
     recognition and enforcement of judgements in civil and commercial matters
     which is binding in The Netherlands, a judgement rendered by a foreign
     court against ABN AMRO will not be recognised and enforced by the courts of
     The Netherlands and in order to obtain a judgement that is enforceable
     against ABN AMRO.  It will be necessary to relitigate the matter before the
     competent court of The Netherlands and to submit the judgment rendered by
     the foreign court in the course of such proceedings, in which case the
     Netherlands' court may give such effect to the foreign judgment as it deems
     appropriate. There are no treaties between The Netherlands and the United
     States of America on the recognition and enforcement of civil or commercial
     judgments.  However, according to current practice, based upon case law,
     Netherlands' courts will in all probability recognize, give "res judicata"
     to and render a judgment in accordance with a foreign judgment if and to
     the extent that the following conditions are met:


     (i)  the foreign court rendering the judgment has jurisdiction over the
          matter on internationally acceptable grounds (e.g. if the parties have
          agreed, for example in a contract, to submit their disputes to the
          foreign court) and has conducted the proceedings in accordance with
          generally accepted principles of fair trial (e.g. after proper
          service of process);

     (ii) the foreign judgment is final and definite; and






<PAGE>   87
                                      -4-


     (iii) such recognition is not in conflict with Netherlands' public policy 
           (i.e. a fundamental principle of Dutch law) or an existing 
           Netherlands' judgment.

7.  Assuming that under the laws of the State of New York to which they are
    expressed to be subject, and any other relevant laws (other than those of
    The Netherlands) the Liquidity Documents constitute general unsecured and
    unsubordinated obligations of ABN AMRO, the payment obligations of ABN AMRO
    under the Liquidity Documents rank at least pari passu with all other
    unsecured and unsubordinated obligations of ABN AMRO (other than those
    obligations preferred by mandatory operation of law and with the exception
    of any rights of set-off or counter-claim which may be asserted against ABN
    AMRO).

8.  Under the laws of The Netherlands, the submission to the jurisdiction of
    the courts of the State of New York, the courts of the United States of
    America for the Southern District of New York and the appellate courts, and
    the waiver of immunities contained in Section [7.11] of the Revolving
    Credit Agreement and Section 10.11 of the Intercreditor Agreement
    constitutes an effective submission by ABN AMBO to the jurisdiction of such
    courts.

The opinions expressed above are subject to the following assumptions:

(1) the Liquidity Documents have been or will be executed in a form the same in
    all material respects as the drafts that we have reviewed for the purpose
    of rendering this opinion;

(2) that each party to the Liquidity Documents (other than ABN AMRO) is duly
    incorporated and organized, and validly existing and in good standing
    (where such concept is legally relevant) under the laws of its
    jurisdiction of incorporation and the jurisdiction of its place of
    business; and

(3) that all signatures on original documents are genuine and all photocopies
    conform to the originals.

We express no opinion as to matters governed by any law other than the laws of
The Netherlands.

This opinion is addressed to you and may not be relied upon by any other
person. Without limiting the foregoing, this opinion may not be published,
transmitted or otherwise communicated to, or filed with, any person, firm,
company or institution, unless we have given our prior explicit written consent
thereto in each instance.

This opinion shall be governed by, be construed in accordance with and be
limited to the law of The Netherlands.



Yours sincerely,

         Form of Opinion of In-house Legal Counsel to the Class B and C

<PAGE>   89

     laws of general applicability relating to or affecting creditors' rights
     and to general equity principles.

     (5)  Neither Morgan Stanley nor MSDWD is required to obtain any
     authorization, consent, approval, exemption or license from, or to file
     any registration with, any governmental authority of the United States of
     America or the State of New York as a condition to the validity of, or for
     the execution and delivery of the Liquidity Agreements or the Guarantee,
     to the performance by Morgan Stanley or MSDWD of its obligations
     thereunder.

     (6)  The execution, delivery and performance of the Liquidity Agreements
     by Morgan Stanley and the Guarantee by MSDWD will not contravene or
     constitute a default under any statute, regulation, rule, order or
     judgment or any governmental authority of the United States of America or
     the State of New York, or under any provision of the Certificate of
     Incorporation or By-Laws of Morgan Stanley or MSDWD.

     In connection with my opinion set forth in paragraph (4) above, I note
that, as of the date of this opinion, a judgment for money in an action in a
Federal or state court in the United States ordinarily would be enforced in the
United States only in United States dollars. The date used to determine the
rate of conversion of a foreign currency into United States dollars will depend
upon various factors, including which court renders the judgment. Under Section
27 of the New York Judiciary Law, a state court in the State of New York
rendering a judgment on an obligation required to be paid in a foreign currency
would be required to render such judgment in such foreign currency, and such
judgment would be converted into United States dollars at the exchange rate
prevailing on the date of entry of the judgment.

     The foregoing opinion is limited to the Federal laws of the United States,
the laws of the State of New York and the General Corporation Law of the State
of Delaware, and I am expressing no opinion as to the effect of the laws of any
other jurisdiction.

     With your approval, I have relied as to certain matters on information
obtained from public officials, officers of Morgan Stanley and MSDWD and other
sources believed by me to be responsible, and I have assumed that the
signatures on all documents examined by me are genuine, assumptions which I
have not independently verified.

     I am furnishing this opinion to you solely for your benefit in connection
with the above-referenced agreement. Except for your own internal use, this
opinion is not to be used or circulated, quoted or otherwise referred to, or
relied upon without my express consent.




                                                         Very truly yours,

To the Addressees listed on

                                Atlas Air, Inc.
             $538,915,000 Pass Through Certificates, Series 1998-1
             -----------------------------------------------------


Ladies and Gentlemen:

          We have acted as special counsel to Morgan Stanley & Co.
Incorporated, BT Alex. Brown Incorporated, Donaldson, Lufkin & Jenrette
Securities Corporation and Goldman, Sachs & Co. (collectively, the "Placement
Agents") in connection with the purchase by the Placement Agents, subject to the
terms and conditions of the Placement Agreement dated January 27, 1998 (the
"Placement Agreement"), among the Placement Agents and Atlas Air, Inc., a
Delaware corporation (the "Company"), of $538,915,000 aggregate principal amount
of Pass Through Certificates, Series 1998-1 (the "Certificates"), having the
aggregate principal amounts, interest rates and final distribution dates set
forth in Schedule A to the Placement Agreement, issued by Wilmington Trust
Company ("WTC"), not in its individual capacity but solely as Trustee (the
"Trustee") of Atlas Air Pass Through Trust 1998-1A-O (the "Class A Trust"),
Atlas Air Pass Through Trust 1998-1B-O (the "Class B Trust") and Atlas Air Pass
Through Trust 1998-1C-O (the "Class C Trust" and, collectively with the Class A
Trust and Class B Trust, the "Trusts") created pursuant to three separate Pass
Through Trust Agreements, each dated as of February 29, 1998 (the "Pass Through
Trust Agreements"), between the Company and the Trustee.
<PAGE>   92
          Certain amounts of interest payable on the Certificates will enjoy the
benefit of separate liquidity facilities. In the case of the Class B Trust and
the Class C Trust, Morgan Stanley Capital Services, Inc. (the "Class B and C
Liquidity Provider") has entered into (i) that certain Revolving Credit
Agreement (1998-1B) and that certain Revolving Credit Agreement (1998-1C)
(collectively, the "Class B and C Liquidity Facilities"), each dated as of
February 9, 1998, between WTC (as Subordination Agent, as agent and as trustee
for the Class B Trust and the Class C Trust, as the case may be) as Borrower,
and the Class B and C Liquidity Provider, and (ii) that certain Intercreditor
Agreement, dated as of February 9, 1998 (the "Intercreditor Agreement"), among
WTC, not in its individual capacity except as expressly provided therein, but
solely as Trustee under the Trusts; ABN AMRO Bank N.V., acting through its
Chicago Branch, and the Class B and C Liquidity Provider, as Liquidity
Providers; and WTC, not in its individual capacity except as expressly provided
therein, but solely as Subordination Agent and Trustee (the Class B and C
Liquidity Facilities and the Intercreditor Agreement being referred to
collectively as the "Class B and C Liquidity Documents").

          This opinion is furnished pursuant to the Section 3(h) of the
Placement Agreement. Capitalized terms used and not otherwise defined herein
have the respective meanings set forth in the Class B and C Liquidity Documents.

          In connection with our opinion herein, we have participated in the
preparation of, or have examined, the Class B and C Liquidity Documents. We
have also examined and relied as to factual matters upon the representations and
warranties contained in or made pursuant to such documents, and upon the
originals, or copies certified or otherwise identified to our satisfaction, of
such records, documents, certificates and other instruments as in our judgment
are necessary or appropriate to enable us to render the opinion expressed
below. In such examination, we have assumed the genuineness of all signatures,
the authenticity of all documents submitted to us as originals and the
conformity with the originals of all documents submitted to us as copies. We
have also assumed that the Class B and C Liquidity Documents have been duly
authorized, executed and delivered by each party thereto and, except as covered
by our opinion set forth below, that the Class B and C Liquidity Documents
constitute the legal, valid and binding obligations of each such party
enforceable against such party in accordance with their respective terms.

          Our opinion is limited to the law of the State of New York, the
General Corporation Law of the State of Delaware and the federal law of the
United States, and we do not express any opinion herein concerning any other
law.

          Based upon and subject to the foregoing, we are of the opinion that
each of the Class B and C Liquidity Documents constitutes the legal, valid and
binding obligation of the Class B and C Liquidity Provider, enforceable
against such party in accordance with its terms, except as (x) enforcement
thereof may be limited by bankruptcy, insolvency (including, without
limitation, all laws relating to fraudulent transfers), reorganization,
moratorium or other similar laws affecting enforcement of creditors' rights
generally and (y)

<PAGE>   93
enforcement thereof is subject to general principles of equity (regardless of
whether enforcement is considered in a proceeding in equity or at law).

opinion letter is not to be used, circulated, quoted or otherwise referred to
for any other purpose.

To the Addresses Listed on 
Exhibit A Attached Hereto

RE:  ATLAS AIR, INC. PASS THROUGH CERTIFICATES, SERIES 1998-1

Ladies and Gentlemen:

          We have acted as special counsel to ABN AMRO Bank N.V., Chicago
Branch ("ABN AMRO") in connection with the transactions contemplated by each of
Deposit Agreement (Class A), Deposit Agreement (Class B) and Deposit Agreement
(Class C) in each case dates as of ______________, 1998 (the "Deposit
Agreements") and between Wilmington Trust Company, not in its individual
capacity except as expressly provided therein, but solely as Escrow Agent and
ABN AMRO, as Depositary.

          Except as otherwise noted herein, all capitalized terms used herein
shall have the respective defined meanings set forth in the Deposit Agreements.

          In connection with our opinion herein, we have (i) examined executed
counterparts of the Deposit Agreements, (ii) relied without independent
investigation or verification, upon the representations and warranties as to
factual matters contained in each of the Operative Agreements and upon
originals or copies, certified or otherwise identified to our satisfaction, of
such corporate records, documents and other instruments as we have deemed
relevant to the rendering of this opinion, and (iii) in such examination
assumed the genuineness of all signatures, the authenticity of all documents
submitted to us as originals and the conformity with the originals of all
documents submitted to us as copies.

          Based upon and subject to the foregoing, it is our opinion that:

     1.   Each of the Deposit Agreements constitutes the legal, valid and
binding obligation of ABN AMRO enforceable against it in accordance with its
terms, except as such enforceability is limited by (i) bankruptcy,
receivership, convervatorship, insolvency, fraudulent transfer, liquidation,
reorganization, moratorium or other laws affecting creditors' rights and
<PAGE>   96
VEDDER PRICE

remedies generally from time to time in effect as the same may be applied in
the event of the bankruptcy, receivership, conservatorship, insolvency,
moratorium,liquidation, reorganization or similar situation of any such party,
or other similar occurrence with respect to any such party or by laws affecting
the rights of creditors of depository institutions, (ii) the possible judicial
application of foreign laws or governmental action affecting creditors' rights
generally, (iii) general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law), public
policy and applicable law relating to fiduciary duties, and (iv) any implied
covenant of good faith and fair dealing.

     2.   ABN AMRO Bank N.V. is licensed by the Office of Banks and Real Estate
of the State of Illinois to maintain its branch at 135 LaSalle Street, Chicago,
Illinois (the "Branch"), in accordance with the banking law of the State of
Illinois and the Branch has the full power, authority and legal right to
execute and deliver the Deposit Agreements.

     3.   The execution, delivery and performance by ABN AMRO of the Deposit
Agreements, and the consummation of the transactions contemplated therein do
not violate any banking law, or any governmental rule or regulation relating
thereto, of the United States of America, the State of Illinois or the State of
New York.

     4.   No authorization, consent, approval or other action by, and no notice
to or filing with, any banking authority or regulatory body of the United
States of America, the State of Illinois or the State of New York is required
for the due execution, delivery and performance by ABN AMRO of the Deposit
Agreements other than administrative and ministerial filings which ABN AMRO is
obligated to make in the ordinary course of its business (which filings we have
assumed have been and will continue to be made in a timely manner).

     5.   The payment obligations of ABN AMRO under the Deposit Agreements
constitute unsecured and unsubordinated obligations of ABN AMRO.

          No opinion is given herein as to (i) the availability of specific
performance or equitable relief of any kind or (ii) any federal or state
securities laws.

          In rendering the opinions set forth above, we have assumed that each
of the parties to the Deposit Agreements has the full power, authority and
legal right to enter into the Deposit Agreements and that the Deposit
Agreements have been duly authorized, executed and delivered by each of such
parties.

          WE NOTE THAT THE OPERATIONS OF ABN AMRO ARE SUBJECT TO THE LAWS AND
REGULATIONS OF THE STATE OF ILLINOIS, INCLUDING THE LAWS AND REGULATIONS
GOVERNING BANK DEPOSITS AND COLLECTIONS.

          We further express no opinion as to the validity, binding effect or
enforceability of (i) purported waivers of any statutory or others rights,
court rules or defenses to obligations or
<PAGE>   97

remedies generally from time to time in effect as the same may be applied in
the event of the bankruptcy, receivership, conservatorship, insolvency,
moratorium, liquidation, reorganization or similar situation of any such
party, or other similar occurrence with respect to any such party or by laws
affecting the rights of creditors of depository institutions, (ii) the possible
judicial application of foreign laws of governmental action affecting
creditors' rights generally, (iii) general principles of equity (regardless of
whether such enforceability is considered in a proceeding in equity or at law),
public policy and applicable law relating to fiduciary duties, and (iv) any
implied covenant of good faith and fair dealing.


     2.   ABN AMRO Bank N.V. is licensed by the Office of Banks and Real Estate
of the State of Illinois to maintain its branch at 135 LaSalle Street, Chicago,
Illinois (the "Branch"), in accordance with the banking law of the State of
Illinois and the Branch has the full power, authority and legal right to
execute and deliver the Deposit Agreements.

     3.   The Execution, delivery and performance by ABN AMRO of the Deposit
Agreements, and the consummation of the transactions contemplated therein do
not violate any banking law, or any governmental rule or regulation relating
thereto, of the United States of America, the State of Illinois or the State 
of New York.

     4.   No authorization, consent, approval or other action by, and no notice
to or filing with, any banking authority or regulatory body of the United

Agreements other than administrative and ministerial filings which ABN AMRO is
obligated to make in the ordinary course of its business (which filing we have
assumed have been and will continue to be made in a timely manner).

performance or equitable relief of any kind or (ii) any federal or state
securities laws.

          In rendering the opinions set forth above, we have assumed that each
of the parties to the Deposit Agreements has the full power, authority and
legal right to enter into the Deposit Agreements and that the Deposit
Agreements have been duly authorized, executed and delivered by each of such
parties.

governing bank deposits and collections and in the event of a conflict between
Illinois law and New York law regarding bank deposits and collections, Illinois
law would prevail.

Dear Sirs,

                                 Series 1998-1



We have acted as Dutch legal counsel to ABN AMRO Bank N.V. ("ABN AMRO"), acting
through its Chicago Branch, in connection with the deposit agreement 1988-1
dated as of [*] January 1998 (the "DEPOSIT AGREEMENT") by and between [ESCROW
AGENT] ("[*]"), as Escrow Agent and ABN AMRO, Chicago Branch as Depositary (the
Deposit Agreement, the Placement Agreement (as defined hereunder) and the
Indemnity Agreement (as defined hereunder) are hereinafter collectively
referred to as the "TRANSACTION DOCUMENTS"). This opinion is being furnished
at your specific request. In such capacity, we have examined the following
documents, as well as such other documents and instruments as we have deemed
necessary or advisable for the purposes of this opinion:

(a)  a draft of the Deposit Agreement dated 26 November 1997;



(c)  a draft of the indemnity agreement dated 26 November 1997 (the "INDEMNITY
     AGREEMENT");
<PAGE>   101
                                     - 2 -

(d)  a copy of the articles of association (statuten) of ABN AMRO as they stand
     on the date hereof since their latest amendment dated 21 September 1991,
     being the currently effective articles of association according to the
     extract referred to in (c) below (the "Articles of Association"); and

(e)  a copy of an official summary extract (beperkt minreksel) dated 19 December
     1997 from the Commercial Register of the Chamber of Commerce of Amsterdam
     relating to the registration of ABN AMRO under number 332587 and confirmed
     to us by the Chamber of Commerce of Amsterdam by telephone on the date
     hereof to have remained unaltered since such date.

All capitalized terms not otherwise defined herein shall have the meaning set
forth in the Transaction Documents.

Based upon the foregoing, we are of the opinion (limited in all respects to the
laws of The Netherlands) that:

1.   ABN AMRO is duly registered with the Commercial Register of the Amsterdam
     Chamber of Commerce as (i) a public company with limited liability
     (noamlace vennootschap), (ii) incorporated on 29 March 1824 and (iii)
     validly existing under the laws of The Netherlands and has the corporate
     power under the laws of The Netherlands to enter into the Transaction
     Documents and to perform its obligations thereunder through its Chicago
     Branch.

2.   The execution, delivery and performance of the Transaction Documents by the
     Chicago Branch of ABN AMRO have been duly authorized by all necessary
     corporate action on the part of ABN AMRO and do not contravene any
     provision of applicable law or regulation in The Netherlands or of the
     Articles of Association and no further authorisation by or any corporate
     action of ABN AMRO is required in connection with the execution, delivery
     and performance by it of the Transaction Documents.

3.   Assuming the Transaction Documents constitute legal, valid and binding
     obligations under the laws of the State of New York, and assuming due
     authorisation, execution and delivery thereof by all other parties to such
     Transaction Documents, the Transaction Documents, when executed and
     delivered by [*] and [*] of ABN AMRO's Chicago Branch, will constitute
     legal, valid and binding obligations of ABN AMRO enforceable against ABN
     AMRO in accordance with their terms, except as such enforceability may be
     limited by bankruptcy, insolvency, liquidation, reorganisation, moratorium
     or other similar laws affecting the rights of creditors against ABN AMRO
     generally, as the same may be applied in the event of bankruptcy,
     insolvency, liquidation or reorganisation of, or other similar occurrence
     with respect to, ABN AMRO or in the event of a moratorium or similar
     occurrence affecting ABN AMRO, and subject to the provisions of Chapter X
     of the Act on the Supervision of the Credit System 1992 (Wet Toericht
     Kredistwezen 1992) regarding emergency measures for credit institutions in
     The Netherlands.

                                     - 3 -

4.   No consent, approval, authorization or order of, or filing with any
     governmental authority or body or any court in The Netherlands is required
     as a condition to the enforceability of ABN AMRO's obligations under the
     Transaction Documents.

5.   The courts of The Netherlands will observe and give effect to the choice
     of the laws of the State of New York as the laws governing the Transaction
     Documents in any proceedings in relation thereto on the basis and within
     the scope of and subject to the limitations imposed by the 1980 Rome
     Convention on the Law Applicable to Contractual Obligations (the "Rome
     Convention").

     With the express reservation that as Dutch lawyers we are not qualified to
     assess the exact meaning and consequences of the terms of the Transaction
     Documents under the laws of the State of New York, on the face of such
     document we are not aware of any provision that is likely to be manifestly
     incompatible with Netherlands' public policy (a limitation on the chosen
     law arising under article 16 Rome Convention) or that is likely to give
     rise to situations where mandatory rules of Netherlands' law will prevail
     over the chosen law of such document (a limitation on the chosen law
     arising under article 7 Rome Convention).  It should also be noted that we
     are not aware of any published order, ruling or decision of a Netherlands'
     court, in which such a court has given overriding effect to foreign
     mandatory rules pertaining to a law other than the chosen (or applicable)
     law or Netherland's law (a limitation on the chosen law arising under
     article 7 (1) Rome Convention) in commercial or financial litigation
     brought before such courts.

6.   In the absence of an applicable treaty or convention providing for the
     recognition and enforcement of judgments in civil and commercial matters
     which is binding in The Netherlands, a judgment rendered by a foreign court
     against ABN AMRO will not be recognised and enforced by the courts of The
     Netherlands and in order to obtain a judgment that is enforceable against
     ABN AMRO, it will be necessary to relitigate the matter before the
     competent court of The Netherlands and to submit the judgment rendered by
     the foreign court in the course of such proceedings, in which case the
     Netherlands' court may give such effect to the foreign judgment as it deems
     appropriate. There are no treaties between The Netherlands and the United
     States of America on the recognition and enforcement of civil or commercial
     judgments. However, according to current practice, based upon case law,
     Netherlands' courts will in all probability recognize, give "jus judicata"
     to and render a judgment in accordance with a foreign judgment if and to
     the extent that the following conditions are met:

     (i)  the foreign court rendering the judgment has jurisdiction over the
          matter on internationally acceptable grounds (e.g. if the parties have
          agreed, for example in a contract, to submit their disputes to the
          foreign court) and has conducted the proceedings in accordance with
          generally accepted principles of fair trial (e.g. after proper service
          of process);

     (ii) the foreign judgment is final and definite; and


<PAGE>   103
                                      -4-

     (iii) such recognition is not in conflict with Netherlands' public policy
           (i.e. a fundamental principle of Dutch law) or an existing
           Netherlands' judgment.

7.   Assuming that under the laws of the State of New York to which they are
     expressed to be subject, and any other relevant laws (other than those of
     The Netherlands) the Transaction Documents constitute general unsecured
     and unsubordinated obligations of ABN AMRO, the payment obligations of ABN
     AMRO under the Transaction Documents rank at least pari passu with all
     other unsecured and unsubordinated obligations of ABN AMRO (other than
     those obligations preferred by mandatory operation of law and with the
     exception of any rights of set-off or counter-claim which may be asserted
     against ABN AMRO).

8.   Each party to the Transaction Documents will alternatively be able to
     proceed directly against ABN AMRO's Head Office in Amsterdam, The
     Netherlands, if ABN AMRO's Chicago Branch defaults in its obligation to
     such party under the Transaction Documents.

[9.  Payments of interest and principal in respect of the Deposits in the
     United States are not subject under the laws of The Netherlands or any
     political subdivision thereof to any withholdings or similar charges or
     deductions, provided the payments are made by ABN AMRO's Chicago Branch.]

The opinions expressed are subject to the following assumptions:

(1)  the Transaction Documents have been or will be executed in a form the same
     in all material respects as the drafts that we have reviewed for the
     purpose of rendering this opinion;

(2)  that each party to the Transaction Documents (other than ABN AMRO) is duly
     incorporated and organised, and validly existing and in good standing
     (where such concept is legally relevant) under the laws of its
     jurisdiction of incorporation and the jurisdiction of its place of
     business; and

(3)  that all signatures on original documents are genuine and all photocopies
     conform to the originals.

We express no opinion as to matters governed by any law other than the laws of
The Netherlands.

This opinion is addressed to you and may not be relied upon by any other
person. Without limiting the foregoing, this opinion may not be published,
transmitted or otherwise communicated to, or filed with, any person, firm,
company or institution, unless we have given out prior explicit written consent
thereto in each instance.

This opinion shall be governed by, be construed in accordance with and be
limited to the law of The Netherlands.

                         REGISTRATION RIGHTS AGREEMENT


                 THIS REGISTRATION RIGHTS AGREEMENT (the "Agreement") is made
and entered into February 9, 1998, among ATLAS AIR, INC., a  Delaware
corporation (the "Company"), MORGAN STANLEY & CO. INCORPORATED ("Morgan
Stanley"), BT ALEX.  BROWN INCORPORATED, DONALDSON, LUFKIN & JENRETTE
SECURITIES CORPORATION and GOLDMAN, SACHS & CO. (collectively with Morgan
Stanley, the "Placement Agents").

                 This Agreement is made pursuant to the Placement Agreement
dated January 27, 1998, among the Company and the Placement Agents (the
"Placement Agreement"), which provides for the sale by the Trustee (as defined
below) to the Placement Agents of (i) $300,254,000 aggregate principal amount
of 7.38% 1998-1A Pass Through Certificates (the "Class A Certificates"), (ii)
$115,481,000 aggregate principal amount of 7.68% 1998-1B Pass Through
Certificates (the "Class B Certificates") and (iii) $123,180,000 aggregate
principal amount of 8.01% 1998-1C Pass Through Certificates (the "Class C
Certificates, and together with the Class A Certificates and the Class B
Certificates, the "Certificates").  In order to induce the Placement Agents to
enter into the Placement Agreement, the Company has agreed to provide to the
Placement Agents and their direct and indirect transferees the registration
rights set forth in this Agreement.  The execution of this Agreement is a
condition to the closing under the Placement Agreement.

                 The Certificates will be issued pursuant to three separate
pass through trust agreements, each to be dated as of February 9, 1998
(collectively the "Original Pass Through Trust  Agreements") between the
Company and Wilmington Trust Company, as trustee under each of the Original
Trusts (as defined below) (each a "Trustee").  The Original Pass Through Trust
Agreements are related to the creation and administration of Atlas Air, Inc.
Pass Through Trust Series 1998-1A-O (the "Class A Trust"), Atlas Air, Inc. Pass
Through Trust Series 1998-1B-O (the "Class B Trust") and Atlas Air, Inc. Pass
Through Trust Series 1998-1C-O (the "Class C Trust"; and together with the
Class A Trust and the Class B Trust and the Class C Trust, the "Original
Trusts").

                 The cash proceeds of the offering of Certificates by each
Original Trust will be paid to First Security Bank, National Association., as
escrow agent (the "Escrow Agent"), under an Escrow and Paying Agent Agreement
among the Escrow Agent, the Placement Agents, the Trustee of such Original
Trust and Wilmington Trust Company, as paying agent (the "Paying Agent"), for
the benefit of the holders of Offered Certificates issued by such Original
Trust.  The Escrow Agent will deposit such cash proceeds (each, a "Deposit")
with the Depositary, in accordance with a Deposit Agreement relating to such
Original Trust (each, a "Deposit Agreement"), and will withdraw Deposits upon
request to allow the Trustee to purchase Equipment Notes (as defined in the
Note Purchase Agreement defined below) referred to herein from time to time
pursuant to a Note Purchase Agreement (the "Note Purchase Agreement") to be
dated as of the Closing Date (as defined in the Placement
<PAGE>   3
                                       2

Agreement) among the Company, Wilmington Trust Company, as Trustee of each of
the Original Trusts, as Subordination Agent and as Paying Agent, and the Escrow
Agent.  Each Escrow Agent will issue receipts to be attached to each related
Certificate representing each holder's fractional undivided interest in amounts
deposited with such Escrow Agent and will pay to such holders through the
related Paying Agent interest accrued on the Deposits and received by such
Paying Agent pursuant to the related Deposit Agreement at a rate per annum
equal to the interest rate applicable to the corresponding Certificates.

                 On the Trust Transfer Date (as defined in the Placement
Agreement), each of the Original Trusts will transfer and assign all of its
assets and rights to a newly-created successor trust with substantially
identical terms except as described in the Final Memorandum (as defined in the
Placement Agreement) (each, a "Successor Trust" and, together with the Original
Trusts, the "Trusts") governed by three separate pass through trust agreements
(collectively the "Successor Pass Through Trust  Agreements" and, together with
the Original Pass Through Trust Agreements, the "Trust Agreements") between the
Company and the Trustee.  Each Certificate outstanding on the Trust Transfer
Date will represent the same interest in the Successor Trust as the Certificate
represented in the Original Trust.  Wilmington Trust Company initially will
also act as trustee of the Successor Trusts (each, a "Successor Trustee").

                 In consideration of the foregoing, the parties hereto agree as

<PAGE>   11
                                       10

                 (i)      that the Exchange Offer is being made pursuant to
         this Registration Rights Agreement and that all Registrable
         Certificates validly tendered will be accepted for exchange;

                 (ii)     the dates of acceptance for exchange (which shall be
         each business day during a period of at least 30 days from the date
         such notice is mailed) (the "Exchange Dates");

                 (iii)    that any Registrable Certificate not tendered will
         remain outstanding and continue to accrue interest, but will not
         retain any rights under this Registration Rights Agreement;

                 (iv)     that Holders electing to have a Registrable
         Certificate exchanged pursuant to the Exchange Offer will be required
         to surrender such Registrable Certificate, together with the enclosed
         letters of transmittal, to the institution and at the address (located
         in the Borough of Manhattan, The City of New York) specified in the
         notice prior to the close of business on the last Exchange Date; and

                 (v)      that Holders will be entitled to withdraw their
         election, not later than the close of business on the last Exchange
         Date, by sending to the institution and at the address (located in the
         Borough of Manhattan, The City of New York) specified in the notice, a
         telegram, telex, facsimile transmission or letter setting forth the
         name of such Holder, the principal amount of Registrable Certificates
         delivered for exchange, and a statement that such Holder is
         withdrawing his election to have such Certificates exchanged.

                 As soon as practicable after the last Exchange Date, the
         Company shall or shall cause the Trustees to:

                 (i)      accept for exchange Registrable Certificates or
         portions thereof tendered and not validly withdrawn pursuant to the
         Exchange Offer;

                 (ii)     deliver, or cause to be delivered, to the Class A
         Trustee for cancellation all Class A Registrable Certificates or
         portions thereof so accepted for exchange by the Company, and issue,
         and cause the Class A Trustee to promptly authenticate and mail to
         each Class A Holder, Class A Exchange Certificates equal in principal
         amount to the principal amount of the Class A Registrable Certificates
         surrendered by such Class A Holder;

                 (iii)    deliver, or cause to be delivered, to the Class B

         and cause the Class B Trustee to promptly
<PAGE>   12
                                       11

         authenticate and mail to each Class B Holder, Class B Exchange
         Certificates equal in principal amount to the principal amount of the
         Class B Registrable Certificates surrendered by such Class B Holder;
         and

                 (iv)     deliver, or cause to be delivered, to the Class C
         Trustee for cancellation all Class C Registrable Certificates or
         portions thereof so accepted for exchange by the Company, and issue,
         and cause the Class C Trustee to promptly authenticate and mail to
         each Class C Holder, Class C Exchange Certificates equal in principal
         amount to the principal amount of the Class C Registrable Certificates
         surrendered by such Class C Holder.

The Company shall use its best efforts 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, rules 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 Placement Agents of the names and addresses of the Holders to
whom the Exchange Offer is made, and the Placement Agents shall have the right,
subject to applicable law, to contact such Holders and otherwise facilitate the
tender of Registrable Certificates in the Exchange Offer.

                 (b)      In the event that (i) the Company determines 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 within 30 days of the effectiveness of an Exchange Offer
Registration Statement or (iii) the Exchange Offer has been completed and in
the opinion of counsel for the Placement Agents a Registration Statement must
be filed and a Prospectus must be delivered by the Placement Agents in
connection with any offering or sale of Registrable Certificates, the Company
shall use its best efforts 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 Certificates, and to have such
Shelf Registration Statement declared effective by the SEC.  The Company agrees
to use its best efforts to keep the Shelf Registration Statement continuously
effective until the second anniversary of the Closing Date or such shorter
period that will terminate when all of the Registrable Certificates covered by
the Shelf Registration Statement have been sold pursuant to the Shelf
Registration Statement.  The Company further agrees 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 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 its best
efforts to cause any such
<PAGE>   13
                                       12

amendment to become effective and such Shelf Registration Statement to become
usable as soon as thereafter practicable.  The Company agrees to furnish to the
Holders of Registrable Certificates copies of any such supplement or amendment
promptly after its being used or filed with the SEC.

                 (c)      The Company 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
Certificates 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 Certificates 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 Shelf Registration Statement will be deemed not to have become
effective during the period of such interference until the offering of
Registrable Certificates pursuant to such Registration Statement may legally
resume.  In the event that neither the consummation of the Exchange Offer nor
the declaration by the Commission of a Shelf Registration to be effective (each
a "Registration Event") occurs on or prior to the 180th day after the date of
the issuance of the Registrable Certificates, the interest rate per annum borne
by the Certificates shall be increased by 0.50%, effective from and including
August 9, 1998, to but excluding the date on which a Registration Event occurs.
In the event that the Shelf Registration Statement ceases to be effective at
any time during the period specified by Section 2(b) hereof for more than 60
days, whether or not consecutive, during any 12-month period, the interest rate
borne by the Certificates shall be increased by 0.50% per annum from the 61st
day of the applicable 12-month period such Shelf Registration Statement ceases
to be effective until such time as the Shelf Registration Statement again
becomes effective.

                 (e)      Without limiting the remedies available to the
Placement Agents and the Holders, the Company acknowledges that any failure by
the Company to comply with its obligations under Section 2(a) and Section 2(b)
hereof may result in material irreparable injury to the Placement Agents 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, each Placement Agent or any Holder may obtain such relief
as may be required to specifically enforce the Company's obligations under
Section 2(a) and Section 2(b) hereof.

                 3.       Registration Procedures.  In connection with the
obligations of the Company with respect to the Registration Statements pursuant

possible:

         Statement to become effective and remain effective in accordance with
         Section 2 hereof;

         post-effective amendments to each Registration Statement as may be
         necessary to (x) keep such Registration Statement effective for the
         applicable period under this Registration Rights Agreement, and (y)
         cause each Prospectus to be supplemented by any required prospectus
         supplement and, as so supplemented, to be filed pursuant to Rule 424
         under the 1933 Act and (z) keep each Prospectus current during the
         period described under Section 4(3) and Rule 174 under the 1933 Act

         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 Certificates; and the
         Company consents 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 Certificates and any such Underwriters
         in connection with the offering and sale of the Registrable
         Certificates 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 Certificates under all applicable state securities or
         "blue sky" laws of such jurisdictions as any Holder of Registrable
         Certificates 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 Certificates owned by such Holder; provided, however, that
         the Company shall not be required to (i) qualify as a foreign

         would not otherwise be required to qualify but for this Section 3(d),
         (ii) file any general consent to service of process or (iii) subject
         itself to taxation in any such jurisdiction if it is not so subject;

                 (e)      in the case of a Shelf Registration, notify each
         Holder of Registrable Certificates, counsel for the Holders and
         counsel for the Placement Agents 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 have been filed and become 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 Certificates
         covered thereby, the representations and warranties of the Company
         contained in any underwriting agreement, securities sales agreement or
         other similar agreement, if any, relating to such offering cease to be
         true and correct in all material respects or if the Company receives
         any notification with respect to the suspension of the qualification
         of the Registrable Certificates 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 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

         Registration Statement and any post-effective amendment thereto

         the selling Holders of Registrable Certificates to facilitate the
         timely preparation and delivery of certificates representing
         Registrable Certificates to be sold and not bearing any restrictive
         legends and enable such Registrable Certificates to be in such
         denominations (consistent with the provisions of the Applicable Trust
         Agreement) 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 Certificates;

                 (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 Certificates, 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 agrees 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
         Placement Agents and their counsel (and, in the case of a Shelf
         Registration Statement, the Holders and their counsel) and make such
         of the representatives of the Company as shall be reasonably requested
         by the Placement Agents or their 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 Placement Agents
         and their counsel (and, in 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 Placement Agents or their counsel
         (and, in the case of a Registration Statement, the Holders or their
         counsel) shall object;
<PAGE>   17
                                       16

                 (k)      obtain a CUSIP number for all Exchange Certificates
         or Registrable Certificates, as the case may be, not later than the
         effective date of a Registration Statement;

                 (l)      cause the Trust Agreements to be qualified under the
         Trust Indenture Act of 1939, as amended (the "TIA") in connection with
         the registration of the Exchange Certificates or Registrable
         Certificates, as the case may be, cooperate with the Trustees and the
         Holders to effect such changes to the Trust Agreements as may be
         required for the Trust Agreements to be so qualified in accordance
         with the terms of the TIA and execute, and use its best efforts to
         cause the Trustees 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 Trust Agreements 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
         Certificates, 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 cause the respective
         officers, directors and employees of the Company 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 its best
         efforts to cause all Registrable Certificates to be listed on any
         securities exchange or any automated quotation system on which similar
         securities issued by the Company are then listed if requested by the
         Majority Holders, to the extent such Registrable Certificates satisfy
         applicable listing requirements;

                 (o)      use its best efforts to cause the Exchange
         Certificates or Registrable Certificates, 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
         Certificates 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 satisfactory notification of the matters to
         be incorporated in such filing; and
<PAGE>   18
                                       17

                 (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 class of Registrable Certificates being sold) in order to expedite
         or facilitate the disposition of such Registrable Certificates
         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
         Certificates with respect to the business of the Company and its
         subsidiaries, the Registration Statement, Prospectus and documents
         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
         (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 Certificates, 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, if necessary, any other certified public accountant
         of any subsidiary of the Company, or of any business acquired by the
         Company for which financial statements and financial data are or are
         required to be included in the Registration Statement) addressed to
         each selling Holder and Underwriter of Registrable Certificates, 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 Certificates being
         sold or the Underwriters, and which are customarily delivered in
         underwritten offerings, to evidence the continued validity of the
         representations and warranties of the Company 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 may
require each Holder of Registrable Certificates to furnish to the Company such
information regarding the Holder and the proposed distribution by such Holder
of such Registrable Certificates as the Company 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 of the happening of
any event of the kind described in Section 3(e)(v) hereof, such Holder will
forthwith discontinue disposition of Registrable Certificates pursuant to a
Shelf 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 the
Company's expense) all copies in its possession, other than permanent file
copies then in such Holder's
<PAGE>   19
                                       18

possession, of the Prospectus covering such Registrable Certificates current at
the time of receipt of such notice.  If the Company shall give any such notice
to suspend the disposition of Registrable Certificates pursuant to a
Registration Statement, the Company shall extend the period during which the
Registration Statement shall be maintained effective pursuant to this
Registration Rights 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 Certificates covered by a Shelf
Registration Statement who desire to do so may sell such Registrable
Certificates 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 Certificates 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 Certificates for its own account in the Exchange Offer in
exchange for Certificates that were acquired by such broker-dealer as a result
of market making or other trading activities (a "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 Certificates.

                 The Company understands 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
Certificates, without naming the Participating Broker-Dealers or specifying the
amount of Exchange Certificates 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 Certificates for
their own accounts, so long as the Prospectus otherwise meets the requirements
of the 1933 Act.

                 (b)      In light of Section 4(a) above, notwithstanding the
other provisions of this Registration Rights Agreement, the Company agrees that
the provisions of this Registration Rights 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 Placement Agents or by one or more Participating Broker-Dealers, in each
case as provided in clause (ii) below, in order to expedite or
<PAGE>   20
                                       19

facilitate the disposition of any Exchange Certificates by Participating
Broker-Dealers consistent with the positions of the Staff recited in Section
4(a) above; provided that:

                 (i)      the Company 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 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 Registration Rights 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 by the Placement Agents or with the reasonable
         request in writing to the Company by one or more broker-dealers who
         certify to the Placement Agents and the Company in writing that they
         anticipate that they will be Participating Broker-Dealers; provided
         that in connection with such application of the Shelf Registration
         procedures set forth in Section 3 to an Exchange Offer Registration,
         the Company shall be obligated (x) to deal only with one entity
         representing the Participating Broker-Dealers, which shall be Morgan
         Stanley 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 Placement
         Agents 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 Placement Agents shall have no liability to the
Company or any Holder with respect to any request that it may make pursuant to
Section 4(b) above.

                 5.       Indemnification and Contribution.         (a)  The
Company agrees to indemnify and hold harmless each Placement Agent, each Holder
and each person, if any, who controls any Placement Agent 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, any Placement Agent or
any Holder, from and against all losses, claims, damages and liabilities
(including, without limitation, any legal or other expenses reasonably incurred
by any Placement Agent, 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 Certificates or Registrable
<PAGE>   21
                                       20

Certificates 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 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 Placement Agents or any Holder
(and, in the case of such losses, claims, damages or liabilities incurred by
Morgan Stanley, by any such untrue statement or omission or alleged untrue
statement or omission based upon information relating to Morgan Stanley Capital
Services, Inc. or to Morgan Stanley, Dean Witter, Discover & Co.) furnished to
the Company in writing by the Placement Agents or any selling Holder expressly
for use therein, provided, however, that the foregoing indemnity agreement with
respect to the Preliminary Memorandum shall not inure to the benefit of any
Placement Agent from whom the person asserting any such losses, claims, damages
or liabilities purchased Offered Certificates, or any person controlling such
Placement Agent, if a copy of the Final Memorandum (as then amended or
supplemented if the Company shall have furnished any amendments thereto) was
not sent or given by or on behalf of such Placement Agent to such person, if
required by law so to have been delivered, at or prior to the written
confirmation of the sale of the Offered Certificates (as so amended or
supplemented) would have cured the defect giving rise to such losses, claims,
damages or liabilities, unless such failure is the result of noncompliance by
the Company with Section 5(a) of the Placement Agreement.  In connection with
any Underwritten Offering permitted by Section 3, the Company 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 1933 Act and the 1934 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, each Placement Agent, 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, any
Placement Agent or 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 to the Placement Agents and the
Holders, but only with reference to information relating to such Holder
furnished to the Company 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).
<PAGE>   22
                                       21

                 (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 of 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 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 Placement Agents and all persons, if any, who control any
Placement Agent within the meaning of either Section 15 of the 1933 Act or
Section 20 of the 1934 Act, (b) the fees and expenses of more than one separate
firm (in addition to any local counsel) for the Company, its directors, its
officers who sign the Registration Statement and each person, if any, who
controls the Company 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 Placement Agents
and persons who control any Placement Agent, such firm shall be designated in
writing by the Placement Agents.  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.  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 60 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
<PAGE>   23
                                       22

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 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 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 Certificates of such Holder that were registered pursuant
to a Registration Statement.

                 (e)      The Company 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 Certificates 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 Placement Agents, any Holder
<PAGE>   24
                                       23

or any person controlling any Placement Agent or any Holder, or by or on behalf
of the Company, its officers or directors or any person controlling the
Company, (iii) acceptance of any of the Exchange Certificates and (iv) any sale
of Registrable Certificates pursuant to a Shelf Registration Statement.

                 6.       Miscellaneous.  (a)  No Inconsistent Agreements.  The
Company has not entered into, and on or after the date of this Registration
Rights Agreement will not enter into, any agreement which is inconsistent with
the rights granted to the Holders of Registrable Certificates in this
Registration Rights 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 other issued and outstanding securities under any such agreements.

                 (b)      Amendments and Waivers.  The provisions of this
Registration Rights 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 has obtained the
written consent of Holders of at least a majority in aggregate principal amount
of the outstanding Registrable Certificates 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 Certificates 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 Placement Agents, the address set forth in the Placement Agreement, and
(ii) if to the Company, initially at the Company's address set forth in the
Placement Agreement and thereafter at such other address, notice of which is
given in accordance with the provisions of this Section 6(c).

                 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 each Trustee,
at the address specified in the Applicable Trust Agreement.

         withdrawals for the purchase of Equipment Notes to be held herein,
         will not constitute Trust Property.

                 "U.S. Physical Certificates" has the meaning specified in

                 Section 1.02.  Compliance Certificates and Opinions.  Upon any
application or request by the Company, any Owner Trustee or any Loan Trustee to
the Trustee to take any action under any provision of this Agreement, the
Company, such Owner Trustee or such Loan Trustee, as the case may be, shall
furnish to the Trustee (i) an Officer's Certificate stating that, in the
opinion of the signers, all conditions precedent, if any, provided for in this
Agreement relating to the proposed action have been complied with and (ii) an
Opinion of Counsel stating that in the opinion of such counsel all such
conditions precedent, if any, have been complied with, except that in the case
of any such application or request as to which the furnishing of such documents
is specifically required by any provision of this Agreement relating to such
particular application or request, no additional certificate or opinion need be
furnished.

                 Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Agreement (other than a certificate
provided pursuant to Section 8.04(d)) shall include:

                 (a)      a statement that each individual signing such
         certificate or opinion has read such covenant or condition and the
         definitions in this Agreement relating thereto;

                 (b)      a brief statement as to the nature and scope of the
         examination or investigation upon which the statements or opinions

<PAGE>   22
                                       16

                 (c)      a statement that, in the opinion of each such
         individual, 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

                 (d)      a statement as to whether, in the opinion of each
         such individual, such condition or covenant has been complied with.

                 Section 1.03.  Form of Documents Delivered to Trustee.  In any
case where several matters are required to be certified by, or covered by an
opinion of, any specified Person, it is not necessary that all such matters be
certified by, or covered by the opinion of, only one such Person, or that they
be so certified or covered by only one document, but one such Person may
certify or give an opinion with respect to some matters and one or more other
such Persons as to other matters and any such Person may certify or give an
opinion as to such matters in one or several documents.

                 Where any Person is required to make, give or execute two or
more applications, requests, consents, certificates, statements, opinions or
other instruments under this Agreement, they may, but need not, be consolidated
and form one instrument.

                 Section 1.04.  Directions of Certificateholders.  (a)  Any
direction, consent, request, demand, authorization, notice, waiver or other
action provided by this Agreement in respect of the Certificates to be given or
taken by Certificateholders (a "Direction") may be embodied in and evidenced by
one or more instruments of substantially similar tenor signed by such
Certificateholders in person or by an agent or proxy 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,
when it is hereby expressly required pursuant to this Agreement, to the Company
or any Loan Trustee.  Such instrument or instruments (and the action embodied
therein and evidenced thereby) are herein sometimes referred to as the "Act" of
the Certificateholders signing such instrument or instruments.  Proof of
execution of any such instrument or of a writing appointing any such agent or
proxy shall be sufficient for any purpose of this Trust Agreement and
conclusive in favor of the Trustee, the Company and the related Loan Trustee,
if made in the manner provided in this Section 1.04.

                 (b)      The fact and date of the execution by any Person of
any such instrument or writing may be proved by the certificate of any notary
public or other officer of any jurisdiction authorized to take acknowledgments
of deeds or administer oaths that the Person executing such instrument
acknowledged to him the execution thereof, or by an affidavit of a witness to
such execution sworn to before any such notary or such other officer, and where
such execution is by an officer of a corporation or association or a member of
a partnership, on behalf of such corporation, association or partnership, such
<PAGE>   23
                                       17

certificate or affidavit shall also constitute sufficient proof of his
authority.  The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other reasonable manner which the Trustee deems sufficient.

                 (c)      In determining whether the Certificateholders of the
requisite Fractional Undivided Interests of Certificates Outstanding have given
any Direction under this Agreement, Certificates owned by the Company or any
Affiliate thereof shall be disregarded and deemed not to be Outstanding for
purposes of any such determination.  In determining whether the Trustee shall
be protected in relying upon any such Direction, only Certificates which the
Trustee knows to be so owned shall be so disregarded.  Notwithstanding the
foregoing, (i) if any such Person owns 100% of the Certificates Outstanding,
such Certificates shall not be so disregarded, and (ii) if any amount of
Certificates so owned by any such Person have been pledged in good faith, such
Certificates shall not be disregarded if the pledgee establishes to the
satisfaction of the Trustee the pledgee's right so to act with respect to such
Certificates and that the pledgee is not the Company or any Affiliate thereof.

                 (d)      The Company may, at its option, by delivery of an
Officer's Certificate to the Trustee, set a record date to determine the
Certificateholders in respect of the Certificates, entitled to give any
Direction.  Notwithstanding Section 316(c) of the Trust Indenture Act, such
record date shall be the record date specified in such Officer's Certificate,
which shall be a date not more than 30 days prior to the first solicitation of
Certificateholders of the applicable series in connection therewith.  If such a
record date is fixed, such Direction may be given before or after such record
date, but only the Certificateholders of record of the applicable series at the
close of business on such record date shall be deemed to be Certificateholders
for the purposes of determining whether Certificateholders of the requisite
proportion of Outstanding Certificates have authorized or agreed or consented
to such Direction, and for that purpose the Outstanding Certificates shall be
computed as of such record date; provided, however, that no such Direction by
the Certificateholders on such record date shall be deemed effective unless it
shall become effective pursuant to the provisions of this Agreement not later
than one year after such record date.

                 (e)      Any Direction by the Holder of any Certificate shall
bind the Holder of every Certificate issued upon the transfer thereof or in
exchange therefor or in lieu thereof, whether or not notation of such Direction
is made upon such Certificate.

                 (f)      Except as otherwise provided in Section 1.04(c),
Certificates owned by or pledged to any Person shall have an equal and
proportionate benefit under the provisions of this Agreement, without
preference, priority or distinction as among all of the Certificates.

                                   ARTICLE II

                       ORIGINAL ISSUANCE OF CERTIFICATES:
                         ACQUISITION OF TRUST PROPERTY

                 Section 2.01.  Delivery of Documents; Delivery Dates.  (a)
The Trustee is hereby directed (i) to execute and deliver the Intercreditor
Agreement, the Escrow Agreement and the Note Purchase Agreement on or prior to
the Issuance Date, each in the form delivered to the Trustee by the Company and
(ii) subject to the respective terms thereof, to perform its obligations
thereunder.  Upon request of the Company and the satisfaction or waiver of the
closing conditions specified in the Placement Agreement, the Trustee shall
execute, deliver, authenticate, issue and sell Certificates in authorized
denominations equaling in the aggregate the amount set forth, with respect to
the Trust, in Schedule II to the Placement Agreement evidencing the entire
ownership interest in the Trust, which amount equals the maximum aggregate
principal amount of Equipment Notes which may be purchased by the Trustee
pursuant to the Note Purchase Agreement.  Except as provided in Sections 3.04
and 3.07 of this Agreement, the Trustee shall not execute, authenticate or
deliver Certificates in excess of the aggregate amount specified in this
paragraph.

                 (b)      On or after the Issuance Date, the Company may
deliver from time to time to the Trustee a Delivery Notice relating to one or
more Equipment Notes.  After receipt of a Delivery Notice and in any case no
later than one Business Day prior to a Delivery Date as to which such Delivery
Notice relates (the "Applicable Delivery Date"), the Trustee shall (as and when
specified in the Delivery Notice) instruct the Escrow Agent to provide a Notice
of Purchase Withdrawal to the Depositary requesting (A) the withdrawal of one
or more Deposits on the Applicable Delivery Date in accordance with and to the
extent permitted by the terms of the Escrow Agreement and the Deposit Agreement
and (B) the payment of all, or a portion, of such Deposit or Deposits in an
amount equal in the aggregate to the purchase price of such Equipment Notes to
or on behalf of the Owner Trustee or the Company, as the case may be, issuing
such Equipment Notes, all as shall be described in the Delivery Notice.  The
Trustee shall (as and when specified in such Delivery Notice), subject to the
conditions set forth in Section 2 of the Note Purchase Agreement, enter into
and perform its obligations under the Participation Agreement specified in such
Delivery Notice (the "Applicable Participation Agreement") and cause such
certificates, documents and legal opinions relating to the Trustee to be duly
delivered as required by the Applicable Participation Agreement.  If at any
time prior to the Applicable Delivery Date, the Trustee receives a notice of
postponement pursuant to Section 1(e) or 1(f) of the Note Purchase Agreement,
then the Trustee shall give the Depositary (with a copy to the Escrow Agent) a
notice of cancellation of such Notice of Purchase Withdrawal relating to such
Deposit or Deposits on such Applicable Delivery Date.  Upon satisfaction of the
conditions specified in the Note Purchase Agreement and the Applicable
Participation Agreement, the Trustee shall
<PAGE>   25
                                       19

purchase the applicable Equipment Notes with the proceeds of the withdrawals of
one or more Deposits made on the Applicable Delivery Date in accordance with
the terms of the Deposit Agreement and the Escrow Agreement.  The purchase
price of such Equipment Notes shall equal the principal amount of such
Equipment Notes.  Amounts withdrawn from such Deposit or Deposits in excess of
the purchase price of the Equipment Notes or to the extent not applied on the
Applicable Delivery Date to the purchase price of the Equipment Notes, shall be
re-deposited by the Trustee with the Depositary on the Applicable Delivery Date
in accordance with the terms of the Deposit Agreement.

                 Section 2.02.  Withdrawal of Deposits.  If any Deposits remain
outstanding on the Business Day next succeeding the Cut-off Date, (i) the
Trustee shall give the Escrow Agent notice that the Trustee's obligation to
purchase Equipment Notes under the Note Purchase Agreement has terminated and
instruct the Escrow Agent to provide a notice of Final Withdrawal to the
Depositary substantially in the form of Exhibit B to the Deposit Agreement (the
"Final Withdrawal Notice") and (ii) the Trustee will make a demand upon the
Company under the Note Purchase Agreement for an amount equal to the Special
Redemption Premium, such payment to be made on the Final Withdrawal Date.

                 Section 2.03.  Acceptance by Trustee.  The Trustee, upon the
execution and delivery of this Agreement, acknowledges its acceptance of all
right, title and interest in and to the Trust Property and will hold such
right, title and interest for the benefit of all then present and future
Certificateholders, upon the trusts herein set forth.  By its payment for and
acceptance of each Certificate issued to it under this Agreement, each initial
Holder of such Certificate as grantor of such Trust shall thereby join in the
creation and declaration of such Trust.

                 Section 2.04.  Limitation of Powers.  The Trust is constituted
solely for the purpose of making the investment in the Equipment Notes, and,
except as set forth herein, the Trustee shall not be authorized or empowered to
acquire any other investments or engage in any other activities and, in
particular, the Trustee shall not be authorized or empowered to do anything
that would cause such Trust to fail to qualify as a "grantor trust" for federal
income tax purposes (including, as subject to this restriction, acquiring any
Aircraft (as defined in the respective Indentures) by bidding such Equipment
Notes or otherwise, or taking any action with respect to any such Aircraft once
acquired).

                                  ARTICLE III

                                THE CERTIFICATES

                 Section 3.01.  Title, Form, Denomination and Execution of
Certificates.  (a)  The Initial Certificates shall be known as the "7.38%
1998-1A-O Initial Pass Through Certificates" and the Exchange Certificates
shall be known as the "7.38% 1998-1A-O Exchange Pass Through Certificates", in
each case, of the Trust.  Each Certificate will represent a fractional
undivided interest in the Trust and shall be substantially in the form set
forth as Exhibit A hereto, with such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by this
Agreement and may have such letters, numbers or other marks of identification
and such legends or endorsements placed thereon as may be required to comply
with the rules of any securities exchange or as may, consistently herewith, be
determined by the officers executing such Certificates, as evidenced by their
execution of the Certificates.  Any portion of the text of any Certificate may
be set forth on the reverse thereof, with an appropriate reference thereto on
the face of the Certificate.

                 (b)      The Initial Certificates shall be issued only in
fully registered form without coupons and only in denominations of $100,000 or
integral multiples of $1,000 in excess thereof, except that one Certificate may
be issued in a denomination of less than $100,000.  The Exchange Certificates
will be issued in denominations of $1,000 or integral multiples thereof.  Each
Certificate shall be dated the date of its authentication.  The aggregate
Fractional Undivided Interest of Certificates shall not at any time exceed
$300,254,000.

                 (c)      Initial Certificates offered and sold in reliance on
Rule 144A shall be issued initially in the form of a single permanent global
Certificate in registered form, substantially in the form set forth as Exhibit
A hereto (the "U.S. Global Certificate"), duly executed and authenticated by
the Trustee as hereinafter provided.  The U.S. Global Certificate will be
registered in the name of a nominee for the Depositary and deposited with the
Trustee, as custodian for the Depositary.  The aggregate principal amount of
the U.S. Global Certificate may from time to time be increased or decreased by
adjustments made on the records of the Depositary or its nominee, or of the
Trustee, as custodian for the Depositary or its nominee, as hereinafter
provided.

                 (d)      Initial Certificates offered and sold in offshore
transactions in reliance on Regulation S shall be issued initially in the form
of a single temporary global Certificate in registered form, substantially in
the form set forth as Exhibit A hereto (the "Temporary Offshore Global
Certificate") duly executed and authenticated by the Trustee as hereinafter
provided.  The Temporary Offshore Global Certificates will be registered in the
name of a nominee of the Depositary for credit to the account of the Agent
Members acting as depositaries for Euroclear and Cedel and deposited with the
Trustee as custodian for the
<PAGE>   27
                                       21

Depositary.  At any time following March 21, 1998 (the "Offshore Certificates
Exchange Date"), upon receipt by the Trustee of a certificate substantially in
the form of Exhibit B hereto, a single permanent global Certificate in
registered form substantially in the form set forth in Exhibit A (the
"Permanent Offshore Global Certificate"; and together with the Temporary
Offshore Global Certificate, the "Offshore Global Certificates"), duly executed
and authenticated by the Trustee as hereinafter provided, shall be registered
in the name of a nominee for the Depositary and deposited with the Trustee, as
custodian for the Depositary, and the Registrar shall reflect on its books and
records the date of such transfer and a decrease in the principal amount of any
Temporary Offshore Global Certificate in an amount equal to the principal
amount of the beneficial interest in such Temporary Offshore Global Certificate
transferred.  The U.S. Global Certificate and the Offshore Global Certificates
are sometimes referred to as the "Global Certificates".

                 (e)      Initial Certificates offered and sold to
Institutional Accredited Investors shall be issued in the form of permanent
certificated Certificates in registered form in substantially the form set
forth as Exhibit A hereto (the "U.S. Physical Certificates").  Certificates
issued pursuant to Section 3.05(b) in exchange for interests in any Offshore
Global Certificate shall be in the form of permanent certificated Certificates
in registered form substantially in the form set forth in Exhibit A (the
"Offshore Physical Certificates").  The Offshore Physical Certificates and U.S.
Physical Certificates are sometimes collectively herein referred to as the
"Physical Certificates".

                 (f)      The Exchange Certificates shall be issued in the form
of one or more global Certificates substantially in the form of Exhibit A
hereto (each, a "Global Exchange Certificate"), except that (i) the Private
Placement Legend (hereinafter defined) shall be omitted and (ii)  such Exchange
Certificates shall contain such appropriate insertions, omissions,
substitutions and other variations from the form set forth in Exhibit A hereto
relating to the nature of the Exchange Certificates as the Responsible Officer
of the Trustee executing such Exchange Certificates on behalf of the Trust may
determine, as evidenced by such officer's execution on behalf of the Trust of
such Exchange Certificates.  Such Global Exchange Certificates shall be in
registered form and be registered in the name of DTC and deposited with the
Trustee, at its Corporate Trust Office, as custodian for DTC.  The aggregate
principal amount of any Global Exchange Certificate may from time to time be
increased or decreased by adjustments made on the records of the Trustee, as
custodian for DTC for such Global Exchange Certificate, which adjustments shall
be conclusive as to the aggregate principal amount of any such Global Exchange
Certificate.  Subject to clause (i) and (ii)  of the first sentence of this
Section 3.01(f), the terms hereof applicable to Restricted Global Certificates
and/or Global Certificates shall apply to the Global Exchange Certificates,
mutatis mutandis.

                 (g)      The definitive Certificates shall be in registered
form and shall be typed, printed, lithographed or engraved or produced by any
combination of these methods
<PAGE>   28
                                       22

or may be produced in any other manner, all as determined by the officers
executing such Certificates, as evidenced by their execution of such
Certificates.

                 Section 3.02.  Restrictive Legends.  (a)  Subject to Section
3.06, unless and until (i) an Initial Certificate is sold under an effective
Registration Statement or (ii) an Initial Certificate is exchanged for an
Exchange Certificate pursuant to an effective Exchange Offer Registration
Statement, in each case as provided for in the Registration Rights Agreement,
each Global Certificate (other than the Permanent Offshore Global Certificate)
and each U.S. Physical Certificate shall bear the following legend (the
"Private Placement Legend") on the face thereof:

                 THIS CERTIFICATE HAS NOT BEEN REGISTERED UNDER THE U.S.
         SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND
         ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR
         TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY PERSONS EXCEPT AS SET FORTH
         IN THE FOLLOWING SENTENCE.  BY ITS ACQUISITION HEREOF, THE HOLDER (1)
         REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS
         DEFINED IN RULE 144A UNDER THE SECURITIES ACT), (B) IT IS AN
         INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)(1),
         (2), (3) OR (7) OF REGULATION D UNDER THE SECURITIES ACT) (AN
         "INSTITUTIONAL ACCREDITED INVESTOR") OR (C) IT IS NOT A U.S.  PERSON
         AND IS ACQUIRING THIS CERTIFICATE IN AN OFFSHORE TRANSACTION IN
         COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT; (2) AGREES THAT
         IT WILL NOT WITHIN TWO YEARS AFTER THE LATER OF THE ORIGINAL ISSUANCE
         OF THIS CERTIFICATE OR THE LAST DATE ON WHICH THIS CERTIFICATE WAS
         HELD BY ATLAS AIR, INC., THE TRUSTEE OR ANY AFFILIATE OF ANY OF SUCH
         PERSONS RESELL OR OTHERWISE TRANSFER THIS CERTIFICATE EXCEPT (A) TO A
         QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE
         SECURITIES ACT, (B) INSIDE THE UNITED STATES TO AN INSTITUTIONAL
         ACCREDITED INVESTOR ACQUIRING $100,000 OR MORE AGGREGATE PRINCIPAL
         AMOUNT OF  SUCH CERTIFICATE THAT, PRIOR TO SUCH TRANSFER, FURNISHES TO
         THE TRUSTEE A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND
         AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THIS
         CERTIFICATE (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM THE
         TRUSTEE), (C) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN
         COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT, (D) PURSUANT TO THE
         EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES
         ACT (IF AVAILABLE) OR (E) PURSUANT TO AN
<PAGE>   29
                                       23

         EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT; AND (3)
         AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS CERTIFICATE IS
         TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.  IN
         CONNECTION WITH ANY TRANSFER OF THIS CERTIFICATE WITHIN TWO YEARS
         AFTER THE LATER OF THE ORIGINAL ISSUANCE OF THIS CERTIFICATE OR THE
         LAST DATE ON WHICH THIS CERTIFICATE WAS HELD BY ATLAS AIR, INC., THE
         TRUSTEE OR ANY AFFILIATE OF ANY OF SUCH PERSONS THE HOLDER MUST CHECK
         THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE
         MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO THE TRUSTEE.
         AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION", "UNITED STATES" AND
         "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER
         THE SECURITIES ACT.  THE PASS THROUGH TRUST AGREEMENT CONTAINS A
         PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF
         THIS CERTIFICATE IN VIOLATION OF THE FOREGOING RESTRICTIONS.

                 (b)      Each Global Certificate shall also bear the following
legend on the face thereof:

         UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE
         OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO
         THE TRUSTEE OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR
         PAYMENT, AND ANY CERTIFICATE ISSUED IN EXCHANGE FOR THIS CERTIFICATE
         IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS
         REQUESTED BY AN AUTHORIZED  REPRESENTATIVE OF DTC (AND ANY PAYMENT
         HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED
         BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER
         USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL
         INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
         HEREIN.

         TRANSFERS OF THIS GLOBAL CERTIFICATE SHALL BE LIMITED TO TRANSFERS IN
         WHOLE, BUT NOT IN PART, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF
         OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL
         CERTIFICATE SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE
         RESTRICTIONS SET FORTH IN SECTIONS 3.05 AND 3.06 OF THE PASS THROUGH
         TRUST AGREEMENT REFERRED TO HEREIN.

                 Section 3.03.  Authentication of Certificates.  (a)  On the
Issuance Date, the Trustee shall duly execute, authenticate and deliver
Certificates in authorized denominations equalling in the aggregate the amount
set forth, with respect to the Trust, in Schedule II to the Placement
Agreement, evidencing the entire ownership of the Trust, which amount equals
the maximum aggregate principal amount of the Equipment Notes which may be
purchased by the Trustee pursuant to the Note Purchase Agreement.

                 (b)      No Certificate shall be entitled to any benefit under
this Agreement or be valid or obligatory for any purpose, unless there appears
on such Certificate a certificate of authentication substantially in the form
provided for herein executed by the Trustee by the manual signature of one of
its authorized signatories, and such certificate upon any Certificate shall be
conclusive evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder.

                 Section 3.04.  Transfer and Exchange.  The Trustee shall cause
to be kept at the office or agency to be maintained by it in accordance with
the provisions of Section 7.12 of this Agreement a register (the "Register")
for the Certificates in which, subject to such reasonable regulations as it may
prescribe, the Trustee shall provide for the registration of the Certificates
and of transfers and exchanges of the Certificates as herein provided.  The
Trustee shall initially be the registrar (the "Registrar") for the purpose of
registering the Certificates and transfers and exchanges of the Certificates as
herein provided.  A Certificateholder may transfer a Certificate by written
application to the Registrar stating the name of the proposed transferee and
otherwise complying with the terms of this Agreement, including providing a
written certificate or other evidence of compliance with any restrictions on
transfer.  No such transfer shall be effected until, and such transferee shall
succeed to the rights of a Certificateholder only upon, final acceptance and
registration of the transfer by the Registrar in the Register.  Prior to the
registration of any transfer by a Certificateholder as provided herein, the
Trustee shall treat the person in whose name the Certificate is registered as
the owner thereof for all purposes, and the Trustee shall not be affected by
notice to the contrary.  Furthermore, the Depositary shall, by acceptance of a
Global Certificate, agree that transfers of beneficial interests in such Global
Certificate may be effected only through a book-entry system maintained by the
Depositary (or its agent), and that ownership of a beneficial interest in the
Certificate shall be required to be reflected in a book entry.  When
Certificates are presented to the Registrar with a request to register the
transfer or to exchange them for an equal face amount of Certificates of other
authorized denominations, the Registrar shall register the transfer or make the
exchange as requested if its requirements for such transactions are met.  To
permit registrations of transfers and exchanges in accordance with the terms,
conditions and restrictions hereof, the Trustee shall execute and authenticate
Certificates at the Registrar's request.  No service charge shall be made for
any registration of transfer or exchange of the Certificates, but the Trustee
may require payment by the transferor of a sum sufficient to cover any transfer
tax or similar governmental charge payable in connection therewith (other than
any such transfer taxes or
<PAGE>   31
                                       25

other similar governmental charges payable upon exchanges pursuant to Section
3.10 or 9.07).

                 Section 3.05.  Book-Entry Provisions for U.S. Global
Certificate and Offshore Global Certificates.  (a) Members of, or participants
in, the Depositary ("Agent Members") shall have no rights under this Agreement
with respect to any Global Certificate held on their behalf by the Depositary,
or the Trustee as its custodian, and the Depositary may be treated by the
Trustee and any agent of the Trustee as the absolute owner of such Global
Certificate for all purposes whatsoever.  Notwithstanding the foregoing,
nothing herein shall prevent the Trustee or any agent of the Trustee from
giving effect to any written certification, proxy or other authorization
furnished by the Depositary or shall 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 Certificate.  Upon the issuance of any Global
Certificate, the Registrar or its duly appointed agent shall record a nominee
of the Depositary as the registered holder of such Global Certificate.

                 (b)      Transfers of any Global Certificate shall be limited
to transfers of such Global Certificate or Offshore Global Certificate in
whole, but not in part, to nominees of the Depositary, its successor or such
successor's nominees.  Beneficial interests in the U.S. Global Certificate and
any Offshore Global Certificate may be transferred in accordance with the rules
and procedures of the Depositary and the provisions of Section 3.06.
Beneficial interests in the U.S. Global Certificate or an Offshore Global
Certificate shall be delivered to all beneficial owners in the form of U.S.
Physical Certificates or Offshore Physical Certificates, as the case may be, if
(i) the Depositary notifies the Trustee that it is unwilling or unable to
continue as Depositary for the U.S. Global Certificate or such Offshore Global
Certificate, as the case may be, and a successor depositary is not appointed by
the Trustee within 90 days of such notice or (ii) an Event of Default has
occurred and is continuing and the Registrar has received a request from the
Depositary to issue Physical Certificates.

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

                 (d)      In connection with the transfer of the entire U.S.
Global Certificate or an entire Offshore Global Certificate to the beneficial
owners thereof pursuant to paragraph (b) of this Section 3.05, such U.S. Global
Certificate or Offshore Global Certificate, as the case may be, shall be deemed
to be surrendered to the Trustee for cancellation, and the Trustee shall
execute, authenticate and deliver, to each beneficial owner identified by the
Depositary in exchange for its beneficial interest in such U.S. Global
Certificate or Offshore
<PAGE>   32
                                       26

Global Certificate, as the case may be, an equal aggregate principal amount of
U.S. Physical Certificates or Offshore Physical Certificates, as the case may
be, of authorized denominations.

                 (e)      Any U.S. Physical Certificate delivered in exchange
for an interest in the U.S. Global Certificate pursuant to paragraph (b) of
this Section 3.05 shall, except as otherwise provided by paragraph (f) of
Section 3.06, bear the Private Placement Legend.

                 (f)      Any Offshore Physical Certificate delivered in
exchange for an interest in an Offshore Global Certificate pursuant to
paragraph (b) of this Section shall, except as otherwise provided by paragraph
(f) of Section 3.06, bear the applicable legend regarding transfer restrictions
set forth in Section 3.02(a).

                 (g)      The registered holder of the U.S. Global Certificate
or any Offshore Global Certificate 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
Agreement or the Certificates.

                 Section 3.06.  Special Transfer Provisions.  Unless and until
(i) an Initial Certificate is sold under an effective Registration Statement,
or (ii) an Initial Certificate is exchanged for an Exchange Certificate
pursuant to an effective Exchange Offer Registration Statement, in each case
pursuant to the Registration Rights Agreement, the following provisions shall
apply to such Initial Certificates:

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

                          (i)     The Registrar shall register the transfer of
                 any Certificate, whether or not such Certificate bears the
                 Private Placement Legend, if (x) the requested transfer is at
                 least three years after the later of the original issue date
                 of the Certificates and the last date on which such
                 Certificate was held by the Company or any affiliate of any
                 such persons or (y) the proposed transferee has delivered to
                 the Registrar a letter substantially in the form of Exhibit D
                 hereto and the aggregate principal amount of the Certificates
                 being transferred is at least $100,000.

                          (ii)    If the proposed transferor is an Agent Member
                 holding a     beneficial interest in the U.S. Global
                 Certificate, 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
<PAGE>   33
                                       27

                 Registrar shall reflect on its books and records the date of
                 the transfer and a decrease in the principal amount of such
                 U.S. Global Certificate in an amount equal to the principal
                 amount of the beneficial interest in such U.S. Global
                 Certificate to be transferred, and the Company shall execute,
                 and the Trustee shall authenticate and deliver to the
                 transferor or at its direction, one or more U.S.  Physical
                 Certificates of like tenor and amount.

                 (b)      Transfers to QIBs.  The following provisions shall
         apply with respect to the registration of any proposed transfer of an
         Initial Certificate to a QIB (excluding Non-U.S. Persons):

                          (i)     If the Certificate to be transferred consists
                 of U.S. Physical  Certificates or an interest in any Temporary
                 Offshore Global Certificate, 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
                 Initial Certificate stating, or has otherwise advised the
                 Trustee 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 Initial Certificate stating, or has otherwise
                 advised the Trustee and the Registrar in writing, that it is
                 purchasing the Initial Certificate for its own account or an
                 account with respect to which it exercises sole investment
                 discretion and that it, or the Person on whose behalf it is
                 acting with respect to 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 Trust and/or 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.

                          (ii)    Upon receipt by the Registrar of the
                 documents referred to in clause (i) above and instructions
                 given in accordance with the Depositary's and the Registrar's
                 procedures therefor, the Registrar shall reflect on its books
                 and records the date of such transfer and an increase in the
                 principal amount of the U.S. Global Certificate in an amount
                 equal to the principal amount of the U.S.  Physical
                 Certificates or interests in the Temporary Offshore Global
                 Certificate, as the case may be, being transferred, and the
                 Trustee shall cancel such Physical Certificates or decrease
                 the amount of such Temporary Offshore Global Certificate so
                 transferred.

                 (c)      Transfers of Interests in the Permanent Offshore
         Global Certificate or Offshore Physical Certificates.  The Registrar
         shall register any transfer of interests in
<PAGE>   34
                                       28

         the Permanent Offshore Global Certificate or Offshore Physical
         Certificates without requiring any additional certification.

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

                          (i)     Prior to the Offshore Certificates Exchange
                 Date, the Registrar shall register any proposed transfer of an
                 Initial Certificate to a Non-U.S. Person upon receipt of a
                 certificate substantially in the form set forth as Exhibit C
                 hereto from the proposed transferor.

                          (ii)    On and after the Offshore Certificates
                 Exchange Date, the Registrar shall register any proposed
                 transfer to any Non-U.S. Person if the Certificate to be
                 transferred is a U.S. Physical Certificate or an interest in
                 the U.S. Global Certificate, upon receipt of a certificate
                 substantially in the form of Exhibit C from the proposed
                 transferor.  The Registrar shall promptly send a copy of such
                 certificate to the Company.

                          (iii)   Upon receipt by the Registrar of (x) the
                 documents, if any, required by paragraph (ii) 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 of such transfer and a decrease in
                 the principal amount of such U.S. Global Certificate in an
                 amount equal to the principal amount of the beneficial
                 interest in such U.S. Global Certificate to be transferred,
                 and (B) 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 Certificate in an amount equal to the
                 principal amount of the U.S. Physical Certificate or the U.S.
                 Global Certificate, as the case may be, to be transferred, and
                 the Trustee shall cancel the Physical Certificate, if any, so
                 transferred or decrease the amount of such U.S. Global
                 Certificate.

                 (e)      Private Placement Legend.  Upon the transfer,
         exchange or replacement of Certificates not bearing the Private
         Placement Legend, the Registrar shall deliver Certificates that do not
         bear the Private Placement Legend.  Upon the transfer, exchange or
         replacement of Certificates bearing the Private Placement Legend, the
         Registrar shall deliver only Certificates that bear the Private
         Placement Legend unless either (i) the circumstances contemplated by
         paragraph (a)(i)(x) or (e)(ii) of this Section 3.06 exist or (ii)
         there is delivered to the Registrar an Opinion of Counsel to
<PAGE>   35
                                       29

         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 Certificate
         bearing the Private Placement Legend, each Holder of such a
         Certificate acknowledges the restrictions on transfer of such
         Certificate set forth in this Agreement and agrees that it will
         transfer such Certificate only as provided in this Agreement.  The
         Registrar shall not register a transfer of any Certificate unless such
         transfer complies with the restrictions on transfer of such
         Certificate set forth in this Agreement.  In connection with any
         transfer of Certificates, each Certificateholder agrees by its
         acceptance of the Certificates to furnish the Registrar or the Trustee
         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 the sufficiency of any
         such certifications, legal opinions or other information.

                 Until such time as no Certificates remain Outstanding, the
Registrar shall retain copies of all letters, notices and other written
communications received pursuant to Section 3.05 or this Section 3.06.  The
Trustee, if not the Registrar at such time, 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 3.07.  Mutilated, Destroyed, Lost or Stolen
Certificates.  If (a) any mutilated Certificate is surrendered to the Registrar
or the Registrar receives evidence to its satisfaction of the destruction, loss
or theft of any Certificate and (b) there is delivered to the Registrar and the
Trustee such security, indemnity or bond, as may be required by them to save
each of them harmless, then, in the absence of notice to the Registrar or the
Trustee that such destroyed, lost or stolen Certificate has been acquired by a
bona fide purchaser, and provided that the requirements of Section 8-405 of the
Uniform Commercial Code in effect in any applicable jurisdiction are met, the
Trustee shall execute, authenticate and deliver, in exchange for or in lieu of
any such mutilated, destroyed, lost or stolen Certificate, a new Certificate or
Certificates, in authorized denominations and of like Fractional Undivided
Interest and bearing a number not contemporaneously outstanding.

                 In connection with the issuance of any new Certificate under
this Section 3.07, the Trustee may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Trustee
and the Registrar) connected therewith.
<PAGE>   36
                                       30

                 Any duplicate Certificate issued pursuant to this Section 3.07
shall constitute conclusive evidence of the appropriate Fractional Undivided
Interest in the Trust, as if originally issued, whether or not the lost, stolen
or destroyed Certificate shall be found at any time.

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

                 Section 3.08.  Persons Deemed Owners.  Prior to due
presentment of a Certificate for registration of transfer, the Trustee, the
Registrar and any Paying Agent may treat the Person in whose name any
Certificate is registered (as of the day of determination) as the owner of such
Certificate for the purpose of receiving distributions pursuant to Article IV
and for all other purposes whatsoever, and none of the Trustee, the Registrar
or any Paying Agent shall be affected by any notice to the contrary.

                 Section 3.09.  Cancellation.  All Certificates surrendered for
payment or transfer or exchange shall, if surrendered to the Trustee or any
agent of the Trustee other than the Registrar, be delivered to the Registrar
for cancellation and shall promptly be cancelled by it.  No Certificates shall
be authenticated in lieu of or in exchange for any Certificates cancelled as
provided in this Section, except as expressly permitted by this Agreement.  All
cancelled Certificates held by the Registrar shall be destroyed and a
certification of their destruction delivered to the Trustee.

                 Section 3.10.  Temporary Certificates.  Until definitive
Certificates are ready for delivery, the Trustee shall authenticate temporary
Certificates.  Temporary Certificates shall be substantially in the form of
definitive Certificates but may have insertions, substitutions, omissions and
other variations determined to be appropriate by the officers executing the
temporary Certificates, as evidenced by their execution of such temporary
Certificates.  If temporary Certificates are issued, the Trustee will cause
definitive Certificates to be prepared without unreasonable delay.  After the
preparation of definitive Certificates, the temporary Certificates shall be
exchangeable for definitive Certificates upon surrender of the temporary
Certificates at the office or agency of the Trustee designated for such purpose
pursuant to Section 7.12, without charge to the Certificateholder.  Upon
surrender for cancellation of any one or more temporary Certificates, the
Trustee shall execute, authenticate and deliver in exchange therefor a like
face amount of definitive Certificates of authorized denominations.  Until so
exchanged, the temporary Certificates shall be entitled to the same benefits
under this Agreement as definitive Certificates.

                 Section 3.11.  Limitation of Liability for Payments.  All
payments and distributions made to Certificateholders shall be made only from
the Trust Property and only to the extent that the Trustee shall have
sufficient income or proceeds from the Trust
<PAGE>   37
                                       31

Property to make such payments in accordance with the terms of Article IV of
this Agreement.  Each Certificateholder, by its acceptance of a Certificate,
agrees that it will look solely to the income and proceeds from the Trust
Property for any payment or distribution due to such Certificateholder pursuant
to the terms of this Agreement and that it will not have any recourse to the
Company, the Trustee, the Loan Trustees, the Liquidity Providers, the Owner
Trustees or the Owner Participants, except as otherwise expressly provided
herein or in the Intercreditor Agreement.

                 The Company is a party to this Agreement solely for purposes
of meeting the requirements of the Trust Indenture Act, and therefore shall not
have any right, obligation or liability hereunder (except as otherwise
expressly provided herein).

                          DISTRIBUTIONS; STATEMENTS TO

                 Section 4.01.  Certificate Account and Special Payments
Account.  (a)  The Trustee shall establish and maintain on behalf of the
Certificateholders a Certificate Account as one or more non-interest-bearing
accounts.  The Trustee shall hold such Certificate Account in trust for the
benefit of the Certificateholders, and shall make or permit withdrawals
therefrom only as provided in this Agreement.  On each day when a Scheduled
Payment is made to the Trustee under the Intercreditor Agreement with respect
to the Certificates, the Trustee, upon receipt thereof, shall immediately
deposit the aggregate amount of such Scheduled Payment in such Certificate
Account.

                 (b)      The Trustee shall establish and maintain on behalf of
the Certificateholders a Special Payments Account as one or more accounts,
which shall be non-interest bearing except as provided in Section 4.04. The
Trustee shall hold the Special Payments Account in trust for the benefit of the
Certificateholders and shall make or permit withdrawals therefrom only as
provided in this Agreement.  On each day when one or more Special Payments are
made to the Trustee under the Intercreditor Agreement and upon payment of the
Special Redemption Premium to the Trustee under the Note Purchase Agreement
with respect to the Certificates, the Trustee, upon receipt thereof, shall
immediately deposit the aggregate amount of such Special Payments in such
Special Payments Account.

                 (c)      The Trustee shall present (or, if applicable, cause
the Subordination Agent to present) to the related Loan Trustee of each
Equipment Note such Equipment Note on the date of its stated final maturity or,
in the case of any Equipment Note which is to be

                                       32

redeemed in whole pursuant to the related Indenture, on the applicable
redemption date under such Indenture.

                 Section 4.02.  Distributions from Certificate Account and

to a series of Certificates or as soon thereafter as the Trustee has confirmed

Equipment Notes held (subject to the Intercreditor Agreement) in the related
Trust on such date, the Trustee shall distribute out of the applicable
Certificate Account the entire amount deposited therein pursuant to Section
4.01(a).  There shall be so distributed to each Certificateholder of record of
such series on the Record Date with respect to such Regular Distribution Date
(other than as provided in Section 11.01 concerning the final distribution) by
check mailed to such Certificateholder, at the address appearing in the
Register, such Certificateholder's pro rata share (based on the Fractional
Undivided Interest in the Trust held by such Certificateholder) of the total
amount in the applicable Certificate Account, except that, with respect to
Certificates registered on the Record Date in the name of a Clearing Agency (or
its nominee), such distribution shall be made by wire transfer in immediately
available funds to the account designated by such Clearing Agency (or such
nominee).

                 (b)      On each Special Distribution Date with respect to any
Special Payment with respect to the Certificates or as soon thereafter as the
Trustee has confirmed receipt of any Special Payments due on the Equipment

Payments Account the entire amount of such applicable Special Payment deposited

Certificateholder of record of such series on the Record Date with respect to
such Special Distribution Date (other than as provided in Section 11.01
concerning the final distribution) by check mailed to such Certificateholder,
at the address appearing in the Register, such Certificateholder's pro rata

                 (c)      The Trustee shall, at the expense of the Company,
cause notice of each Special Payment with respect to a series of Certificates
to be mailed to each Certificateholder at his address as it appears in the
Register.  In the event of redemption or purchase of Equipment Notes held in
the related Trust, such notice shall be mailed not less than 15 days prior to
the Special Distribution Date for the Special Payment resulting from such
redemption or purchase, which Special Distribution Date shall be the date of
such redemption or
<PAGE>   39
                                       33

purchase.  In the event that any Special Redemption Premium is to be paid by
the Company to the Trustee under the Note Purchase Agreement, such notice shall
be mailed, together with the notice by the Escrow Paying Agent under Section
2.06 of the Escrow Agreement, not less than 20 days prior to the Special
Distribution Date for such amount, which Special Distribution Date shall be the
Final Withdrawal Date.  In the case of any other Special Payments, such notice
shall be mailed as soon as practicable after the Trustee has confirmed that it
has received funds for such Special Payment, stating the Special Distribution
Date for such Special Payment which shall occur not less than 15 days after the
date of such notice and as soon as practicable thereafter.  Notices mailed by
the Trustee shall set forth:

                 (i)      the Special Distribution Date and the Record Date
         therefor (except as otherwise provided in Section 11.01);

                 (ii)     the amount of the Special Payment for each $1,000
         face amount Certificate and the amount thereof constituting principal,
         premium, if any, and interest;

                 (iii)    the reason for the Special Payment; and

                 (iv)     if the Special Distribution Date is the same date as
         a Regular Distribution Date for the Certificates, the total amount to
         be received on such date for each $1,000 face amount Certificate.

If the amount of (i) premium, if any, payable upon the redemption or purchase
of an Equipment Note or (ii) the Special Redemption Premium, if any, has not
been calculated at the time that the Trustee mails notice of a Special Payment,
it shall be sufficient if the notice sets forth the other amounts to be
distributed and states that any premium received will also be distributed.

                 If any redemption of the Equipment Notes held in any Trust is
cancelled, the Trustee, as soon as possible after learning thereof, shall cause
notice thereof to be mailed to each Certificateholder at its address as it
appears on the Register.

(iv) and (v) below) the following information:

         indicating the amount allocable to each source;

                 (ii)     the amount of such distribution under this Agreement
         allocable to principal and the amount allocable to premium (including
         the Special Redemption Premium), if any;

                 (iii)    the amount of such distribution under this Agreement
         allocable to interest;

                 (iv)     the amount of such distribution under the Escrow
         Agreement allocable to interest;

                 (v)      the amount of such distribution under the Escrow
         Agreement allocable to Deposits; and

                 (b)      Within a reasonable period of time after the end of
each calendar year but not later than the latest date permitted by law, the
Trustee shall furnish to each Person who at any time during such calendar year
was a Certificateholder of record a statement containing the sum of the amounts

year, for the applicable portion of such year, and such other items as are
readily available to the Trustee and which a Certificateholder shall reasonably
request as necessary for the purpose of such Certificateholder's preparation of
its federal income tax returns.  Such statement and such other items shall be
prepared on the basis of information supplied to the Trustee by the Clearing
Agency Participants and shall be delivered by the Trustee to such Clearing
Agency Participants to be available for forwarding by such Clearing Agency
Participants to the holders of interests in the Certificates in the manner

the names of all Clearing Agency Participants reflected on such Clearing
Agency's books as holding interests in the Certificates on such date.  The
Trustee will mail to each such Clearing Agency Participant the statement

         Certificates upon ten days' written notice to the Trustee, the Class B
         Trustee, the Class C Trustee and each other Class D Certificateholder,

         Class D Certificateholder notifies such purchasing Class D
         Certificateholder that such other Class D Certificateholder wants to
         participate in such purchase, then such other Class D

interest thereon to the date of such purchase, without premium, but including
any other amounts then due and payable to the Certificateholders under this

Document or on or in respect of the Certificates; provided, however, that (i)
if such purchase occurs after the record date specified in Section 2.03(b) of
the Escrow Agreement relating to the distribution of unused Deposits and

the aggregate amount of unused Deposits and interest to be distributed under
the Escrow Agreement (which deducted amounts shall remain distributable to, and
may be retained by, the Certificateholder as of such Record Date) and (ii) if
such purchase occurs after a Record Date, such purchase price shall be reduced
by the amount to be distributed hereunder on the related Distribution Date
(which deducted amounts shall remain distributable to, and may be retained by,
the Certificateholder as of such Record Date); provided further that no such
purchase of Certificates shall be effective unless the purchaser(s) shall
certify to the Trustee that contemporaneously with such purchase, such
purchaser(s) is purchasing, pursuant to the terms of this Agreement and the
Other Agreements, the Certificates, the Class B Certificates and the Class C
Certificates which are senior to the securities held by such purchaser(s).

interest and obligation of such Certificateholder in this Agreement, the Escrow
Agreement, the Deposit Agreement, the Intercreditor Agreement, the Liquidity
Facilities, the Note Documents and all Certificates and Escrow Receipts held by
such Certificateholder (excluding all right, title and interest under any of
the foregoing to the extent such right, title or interest is with respect to an
obligation not then due and payable as respects any action or inaction or state
of affairs occurring prior to such sale) and the purchaser shall assume all of
such Certificateholder's obligations under this Agreement, the Escrow
Agreement, the Deposit Agreement, the Intercreditor Agreement, the Liquidity
Facilities, the Note Documents and all such Certificates and Escrow Receipts.
The Certificates will be deemed to be purchased on the date payment of the
purchase price is made notwithstanding the failure of the Certificateholders to
deliver any Certificates and, upon such a purchase, (i) the only rights of the
Certificateholders will be to deliver the Certificates to the purchaser(s) and
receive the purchase price for such Certificates and (ii) if the purchaser(s)
shall so request, such Certificateholder will comply with all the provisions of
Section 3.04 of this Agreement to enable new Certificates to be issued to the
purchaser in such denominations as it shall request.  All charges and expenses
in connection with the issuance of any such new Certificates shall be borne by

         of sale, may hold, retain, possess and dispose of such Equipment Notes
         in their own absolute right without further accountability.

                 (b)      Receipt of Trustee Shall Discharge Purchaser.  The
         receipt of the Trustee making such sale shall be a sufficient
         discharge to any purchaser for his purchase money, and, after paying
         such purchase money and receiving such receipt,
<PAGE>   46
                                       40

         such purchaser or its personal representative or assigns shall not be
         obliged to see to the application of such purchase money, or be in any
         way answerable for any loss, misapplication or nonapplication thereof.

                 (c)      Application of Moneys Received upon Sale.  Any moneys
         collected by the Trustee upon any sale made either under the power of
         sale given by this Agreement or otherwise for the enforcement of this
         Agreement shall be applied as provided in Section 4.02.

                 Section 6.03.  Judicial Proceedings Instituted by Trustee;
Trustee May Bring Suit.  If there shall be a failure to make payment of the
principal of, premium, if any, or interest on any Equipment Note held in the
Trust, or if there shall be any failure to pay Rent (as defined in the relevant
Lease) under any Lease when due and payable, then the Trustee, in, its own name
and as trustee of an express trust, as holder of such Equipment Notes, to the
extent permitted by and in accordance with the terms of any related
Intercreditor Agreement and any related Note Documents (subject to rights of
the applicable Owner Trustee or Owner Participant to cure any such failure to
pay principal of, premium, if any, or interest on any Equipment Note or to pay
Rent under any Lease in accordance with the applicable Indenture), shall be
entitled and empowered to institute any suits, actions or proceedings at law,
in equity or otherwise, for the collection of the sums so due and unpaid on
such Equipment Notes or under such Lease and may prosecute any such claim or
proceeding to judgment or final decree with respect to the whole amount of any
such sums so due and unpaid.

                 Section 6.04.  Control by Certificateholders.  Subject to
Section 6.03 and the Intercreditor Agreement, the Certificateholders holding
Certificates evidencing Fractional Undivided Interests aggregating not less
than a majority in interest in the related Trust shall have the right to direct

available to the Trustee with respect to the Trust or pursuant to the terms of
the Intercreditor Agreement, or exercising any trust or power conferred on the
Trustee under this Agreement or the Intercreditor Agreement, including any
right of the Trustee as Controlling Party under the Intercreditor Agreement or
as holder of the Equipment Notes held in the related Trust; provided, however,
that

                 (a)      such Direction shall not in the opinion of the
         Trustee be in conflict with any rule of law or with this Agreement and
         would not involve the Trustee in personal liability or expense,

                 (b)      the Trustee shall not determine that the action so
         directed would be unjustly prejudicial to the Certificateholders not
         taking part in such Direction, and
<PAGE>   47
                                       41

                 (c)      the Trustee may take any other action deemed proper
         by the Trustee which is not inconsistent with such Direction.

                 Section 6.05.  Waiver of Past Defaults.  Subject to any
related Intercreditor Agreement, the Certificateholders holding Certificates of
a series evidencing Fractional Undivided Interests aggregating not less than a
majority in interest in the Trust (i) may on behalf of all of the
Certificateholders waive any past Event of Default hereunder and its
consequences or (ii) if the Trustee is the Controlling Party, may direct the
Trustee to instruct the applicable Loan Trustee to waive any past Indenture
Event of Default under any related Indenture and its consequences, and thereby
annul any Direction given by such Certificateholders or the Trustee to such
Loan Trustee with respect thereto, except a default:

                 (a)      in the deposit of any Scheduled Payment or Special
         Payment under Section 4.01 or in the distribution of any payment under
         Section 4.02 on the Certificates, or

                 (b)      in the payment of the principal of (premium, if any)
         or interest on the Equipment Notes held in the Trust, or

                 (c)      in respect of a covenant or provision hereof which
         under Article IX hereof cannot be modified or amended without the
         consent of each Certificateholder holding an Outstanding Certificate
         of a series affected thereby.

Upon any such waiver, such default shall cease to exist with respect to the
Certificates and any Event of Default arising therefrom shall be deemed to have
been cured for every purpose and any direction given by the Trustee on behalf
of the Certificateholders to the relevant Loan Trustee shall be annulled with
respect thereto; but no such waiver shall extend to any subsequent or other
default or Event of Default or impair any right consequent thereon.  Upon any
such waiver, the Trustee shall vote the Equipment Notes issued under the
relevant Indenture to waive the corresponding Indenture Event of Default.

                 Section 6.06.  Right of Certificateholders to Receive Payments
Not to Be Impaired.  Anything in this Agreement to the contrary
notwithstanding, including, without limitation, Section 6.07 hereof, but
subject to the Intercreditor Agreement, the right of any Certificateholder to
receive distributions of payments required pursuant to Section 4.02 hereof on
the applicable Certificates when due, or to institute suit for the enforcement
of any such payment on or after the applicable Regular Distribution Date or
Special Distribution Date, shall not be impaired or affected without the
consent of such Certificateholder.

                 Section 6.07.  Certificateholders May Not Bring Suit Except
Under Certain Conditions.  A Certificateholder shall not have the right to

                                       42

appointment of a receiver or for the enforcement of any other remedy under this
Agreement, unless:

                 (a)      such Certificateholder previously shall have given
         written notice to the Trustee of a continuing Event of Default;

                 (b)      Certificateholders holding Certificates evidencing
         Fractional Undivided Interests aggregating not less than 25% of the
         related Trust shall have requested the Trustee in writing to institute
         such action, suit or proceeding and shall have offered to the Trustee
         indemnity as provided in Section 7.03(e);

                 (c)      the Trustee shall have refused or neglected to
         institute any such action, suit or proceeding for 60 days after
         receipt of such notice, request and offer of indemnity; and

                 (d)      no direction inconsistent with such written request
         shall have been given to the Trustee during such 60-day period by
         Certificateholders holding Certificates evidencing Fractional
         Undivided Interests aggregating not less than a majority in interest
         in the Trust.

                 It is understood and intended that no one or more of the
Certificateholders shall have any right in any manner whatsoever hereunder or
under the related Trust Supplement or under the Certificates to (i) surrender,
impair, waive, affect, disturb or prejudice any property in the Trust Property
of the Trust, or the lien of any related Indenture on any property subject
thereto, or the rights of the Certificateholders or the holders of the
Equipment Notes, (ii) obtain or seek to obtain priority over or preference with
respect to any other such Certificateholder or (iii) enforce any right under
this Agreement, except in the manner herein provided and for the equal, ratable
and common benefit of all the Certificateholders subject to the provisions of
this Agreement.

                 Section 6.08.  Remedies Cumulative.  Every remedy given
hereunder to the Trustee or to any of the Certificateholders shall not be
exclusive of any other remedy or remedies, and every such remedy shall be
cumulative and in addition to every other remedy given hereunder or now or
hereafter given by statute, law, equity or otherwise.

                 Section 6.09.  Undertaking for Costs.  In any suit for the
enforcement of any right or remedy under this Agreement, or in any suit against
the Trustee for any action taken, suffered or omitted by it as Trustee, a court
may require any party litigant in such suit to file an undertaking to pay the
costs of such suit, and may assess costs against any such party litigant, in
the manner and to the extent provided in the Trust Indenture Act; provided,
however, that neither this Section 6.09 nor the Trust Indenture Act shall be
deemed to
<PAGE>   49
                                       43

authorize any court to require such an undertaking or to make such an
assessment in any suit instituted by the Company.


                                  ARTICLE VII

                                  THE TRUSTEE

                 Section 7.01.  Certain Duties and Responsibilities.  (a)
Except during the continuance of an Event of Default in respect of a Trust, the
Trustee undertakes to perform such duties in respect of the Trust as are
specifically set forth in this Agreement, and no implied covenants or
obligations shall be read into this Agreement against the Trustee.

                 (b)      In case an Event of Default in respect of a Trust has
occurred and is continuing, the Trustee shall exercise such of the rights and
powers vested in it by this Agreement in respect of the Trust, and use the same
degree of care and skill in their exercise, as a prudent man would exercise or
use under the circumstances in the conduct of his own affairs.

                 (c)      No provision of this Agreement 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

                 (i)      this Subsection shall not be construed to limit the
         effect of Subsection (a) of this Section 7.01; and

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

                 (d)      Whether or not herein expressly so provided, every
provision of this Agreement relating to the conduct or affecting the liability
of or affording protection to the Trustee shall be subject to the provisions of
this Section 7.01.

                 Section 7.02.  Notice of Defaults.  As promptly as practicable
after, and in any event within 90 days after, the occurrence of any default (as
such term is defined below) hereunder known to the Trustee, the Trustee shall
transmit by mail to the Company, any Owner Trustees, the Owner Participants,
the Loan Trustees and the Certificateholders holding Certificates in accordance
with Section 313(c) of the Trust Indenture Act, notice of such default
hereunder known to the Trustee, unless such default shall have been cured or
waived; provided, however, that, except in the case of a default in the payment
of the principal, premium, if any, or interest on any Equipment Note, the
Trustee shall be protected
<PAGE>   50
                                       44

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 shall determine that the withholding of
such notice is in the interests of the Certificateholders.  For the purpose of
this Section 7.02 in respect of any Trust, the term "default" means any event
that is, or after notice or lapse of time or both would become, an Event of
Default in respect of that Trust.

                 Section 7.03.  Certain Rights of Trustee.  Subject to the
provisions of Section 315 of the Trust Indenture Act:

                 (a)      the Trustee may rely and shall be protected in acting
         or refraining from acting in reliance upon any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture or other paper or document
         believed by it to be genuine and to have been signed or presented by
         the proper party or parties;

                 (b)      any request or direction of the Company mentioned
         herein shall be sufficiently evidenced by a Request;

                 (c)      whenever in the administration of this Agreement or
         the Intercreditor Agreement, 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 Officer's Certificate of the Company, any Owner
         Trustee or any Loan Trustee;

                 (d)      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;

                 (e)      the Trustee shall be under no obligation to exercise
         any of the rights or powers vested in it by this Agreement or the
         Intercreditor Agreement at the Direction of any of the
         Certificateholders pursuant to this Agreement or the Intercreditor
         Agreement, unless the Certificateholders shall have offered to the
         Trustee reasonable security or indemnity against the cost, expenses
         and liabilities which might be incurred by it in compliance with such
         Direction;

                 (f)      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 or other paper or document;
<PAGE>   51
                                       45


                 (g)      the Trustee may execute any of the trusts or powers
         under this Agreement or the Intercreditor Agreement or perform any
         duties under this Agreement or the Intercreditor Agreement 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 under this Agreement
         or the Intercreditor Agreement;

                 (h)      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 Certificateholders holding Certificates
         evidencing Fractional Undivided Interests aggregating not less than a
         majority in interest in the Trust relating to the time, method and
         place of conducting any proceeding for any remedy available to the
         Trustee, or exercising any trust or power conferred upon the Trustee,
         under this Agreement or the Intercreditor Agreement; and

                 (i)      the Trustee shall not be required to expend or risk
         its own funds in the performance of any of its duties under this
         Agreement, 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 is not reasonably
         assured to it.

                 Section 7.04.  Not Responsible for Recitals or Issuance of
Certificates.  The recitals contained herein and in the Certificates, except
the certificates of authentication, shall not be taken as the statements of the
Trustee, and the Trustee assumes no responsibility for their correctness.
Subject to Section 7.15, the Trustee makes no representations as to the
validity or sufficiency of this Agreement, any Equipment Notes, the
Intercreditor Agreement, the Deposit Agreement, the Escrow Agreement, the
Certificates, or any Note Documents, except that the Trustee hereby represents
and warrants that this Agreement has been, and the Registration Rights
Agreement, each Certificate, the Note Purchase Agreement, the Escrow Agreement
and the Intercreditor Agreement will be, executed and delivered by one of its
officers who is duly authorized to execute and deliver such document on its
behalf.

                 Section 7.05.  May Hold Certificates.  The Trustee, any Paying
Agent, Registrar or any of their Affiliates or any other agent, in their
respective individual or any other capacity, may become the owner or pledgee of
Certificates and, subject to Sections 310(b) and 311 of the Trust Indenture
Act, if applicable, may otherwise deal with the Company, any Owner Trustees or
the Loan Trustees with the same rights it would have if it were not Trustee,
Paying Agent, Registrar or such other agent.

                 Section 7.06.  Money Held in Trust.  Money held by the Trustee
or the Paying Agent in trust under this Agreement need not be segregated from
other funds except to the extent required herein or by law and neither the
Trustee nor the Paying Agent shall have any liability for interest upon any
such moneys except as provided for herein.

                                       46


                 Section 7.07.  Compensation and Reimbursement.  The Company
agrees:

                 (a)      to pay, or cause to be paid, to the Trustee from time
         to time  reasonable compensation for all services rendered by it
         hereunder (which compensation shall not be limited by any provision of
         law in regard to the compensation of a trustee of an express trust);
         and

                 (b)      to reimburse, or cause to be reimbursed, the Trustee
         upon its request for all reasonable out- of-pocket expenses,
         disbursements and advances incurred or made by the Trustee in
         accordance with any provision of this Agreement or the Intercreditor
         Agreement (including the reasonable compensation and the expenses and
         disbursements of its agents and counsel), except any such expense,
         disbursement or advance as may be attributable to its negligence,
         willful misconduct or bad faith or as may be incurred due to the
         Trustee's breach of its representations and warranties set forth in
         Section 7.15; and

                 (c)      to indemnify the Trustee with respect to the
         Certificates, pursuant to Section 8.1 of the Owned Aircraft
         Participation Agreements and Section 9.1 of the Leased Aircraft
         Participation Agreements, as the case may be.

                 The Trustee shall be entitled to reimbursement from, and shall
have a lien prior to the Certificates upon, all property and funds held or
collected by the Trustee in its capacity as Trustee for any tax incurred
without negligence, bad faith or willful misconduct, on its part, arising out
of or in connection with the acceptance or administration of the Trust (other
than any tax attributable to the Trustee's compensation for serving as such),
including any costs and expenses incurred in contesting the imposition of any
such tax.  The Trustee shall notify the Company of any claim for any tax for
which it may seek reimbursement.  If the Trustee reimburses itself from the
Trust Property of such Trust for any such tax, it will mail a brief report
within 30 days setting forth the amount of such tax and the circumstances
thereof to all Certificateholders as their names and addresses appear in the
Register.

                 Section 7.08.  Corporate Trustee Required; Eligibility.  The
Trust shall at all times have a Trustee which shall be eligible to act as a
trustee under Section 310(a) of the Trust Indenture Act and shall have a
combined capital and surplus of at least $75,000,000 (or a combined capital and
surplus in excess of $5,000,000 and the obligations of which, whether now in
existence or hereafter incurred, are fully and unconditionally guaranteed by a
corporation organized and doing business under the laws of the United States,
any state or territory thereof or of the District of Columbia and having a
combined capital and surplus of at least $75,000,000).  If such corporation
publishes reports of conditions at least annually, pursuant to law or to the
requirements of federal, state, territorial or District of Columbia supervising
or examining authority, then for the purposes of this Section 7.08 the combined
<PAGE>   53
                                       47

capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of conditions so
published.

                 In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 7.08 to act as Trustee of the
Trust, the Trustee shall resign immediately as Trustee of the Trust in the
manner and with the effect specified in Section 7.09.

                 Section 7.09.  Resignation and Removal; Appointment of
Successor.  (a)  No resignation or removal of the Trustee and no appointment of
a successor Trustee of the Trust pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee under
Section 7.10.

                 (b)      The Trustee may resign at any time as Trustee of the
Trust by giving prior written notice thereof to the Company, the Authorized
Agents, the Owner Trustees and the Loan Trustees.  If an instrument of
acceptance by a successor Trustee shall not have been delivered to the Company,
the Owner Trustees and the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

                 (c)      The Trustee may be removed at any time by Direction
of the Certificateholders holding Certificates evidencing Fractional Undivided
Interests aggregating not less than a majority in interest in such Trust
delivered to the Trustee and to the Company, the Owner Trustees and the Loan
Trustees.

                 (d)      If at any time in respect of the Trust:

                 (i)      the Trustee shall fail to comply with Section 310 of
         the Trust Indenture Act, if applicable, after written request therefor
         by the Company or by any Certificateholder who has been a bona fide
         Certificateholder for at least six months; or

                 (ii)     the Trustee shall cease to be eligible under Section
         7.08 and shall fail to resign after written request therefor by the
         Company or by any such Certificateholder; or

                 (iii)    the Trustee shall become incapable of acting or shall
         be adjudged a bankrupt or insolvent, or a receiver of the Trustee or
         of its property shall be appointed or any public officer shall take
         charge or control of the Trustee or of its property or affairs for the
         purpose of rehabilitation, conservation or liquidation;
<PAGE>   54
                                       48

then, in any case, (i) the Company may remove the Trustee or (ii) any
Certificateholder who has been a bona fide Certificateholder for at least six
months may, on behalf of itself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee of the Trust.

                 (e)      If a Responsible Officer of the Trustee shall obtain
actual knowledge of an Avoidable Tax (as defined below) in respect of any Trust
which has been or is likely to be asserted, the Trustee shall promptly notify
the Company and shall, within 30 days of such notification, resign as Trustee
of such Trust hereunder unless within such 30-day period the Trustee shall have
received notice that the Company has agreed to pay such tax.  The Company shall
promptly appoint a successor Trustee of such Trust in a jurisdiction where
there are no Avoidable Taxes.  As used herein, an "Avoidable Tax" in respect of
such Trust means a state or local tax:  (i) upon (w) such Trust, (x) such Trust
Property, (y) Certificateholders of the Trust or (z) the Trustee for which the
Trustee is entitled to seek reimbursement from the Trust Property of such
Trust, and (ii) which would be avoided if the Trustee were located in another
state, or jurisdiction within a state, within the United States of America.  A
tax shall not be an Avoidable Tax in respect of any Trust if the Company or any
Owner Trustee shall agree to pay, and shall pay, such tax.

                 (f)      If the Trustee shall resign, be removed or become
incapable of acting as Trustee of the Trust or if a vacancy shall occur in the
office of the Trustee of the Trust for any cause, the Company shall promptly
appoint a successor Trustee.  If, within one year after such resignation,
removal or incapability, or other occurrence of such vacancy, a successor
Trustee shall be appointed by Direction of the Certificateholders holding
Certificates evidencing Fractional Undivided Interests aggregating not less
than a majority in interest in such Trust delivered to the Company, the Owner
Trustees, the Loan Trustee and the retiring Trustee, then the successor Trustee
so appointed shall, with the approval of the Company of such appointment, which
approval shall not be unreasonably withheld, forthwith upon its acceptance of
such appointment, become the successor Trustee and supersede the successor
Trustee appointed as provided above.  If no successor Trustee shall have been
so appointed as provided above and accepted appointment in the manner
hereinafter provided, the resigning Trustee or any Certificateholder who has
been a bona fide Certificateholder of the related series for at least six
months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the appointment of a successor Trustee.

                 (g)      The successor Trustee shall give notice of the
resignation and removal of the Trustee and appointment of the successor Trustee
by mailing written notice of such event by first-class mail, postage prepaid,
to the Certificateholders as their names and addresses appear in the Register.
Each notice shall include the name of such successor Trustee and the address of
its Corporate Trust Office.
<PAGE>   55
                                       49

                 Section 7.10.  Acceptance of Appointment by Successor.  Every
successor Trustee appointed hereunder shall execute and deliver to the Company
and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on request of the Company or the successor
Trustee, such retiring Trustee shall execute and deliver an instrument
transferring to such successor Trustee all such rights, powers and trusts of
the retiring Trustee and shall duly assign, transfer and deliver to such
successor Trustee all Trust Property held by such retiring Trustee, subject
nevertheless to its lien, if any, provided for in Section 7.07.  Upon request
of any such successor Trustee, the Company, the retiring Trustee and such
successor Trustee shall execute and deliver any and all instruments containing
such provisions as shall be necessary or desirable to transfer and confirm to,
and for more fully and certainly vesting in, such successor Trustee all such
rights, powers and trusts.

                 No institution shall accept its appointment as a Trustee
hereunder unless at the time of such acceptance such institution shall be
qualified and eligible under this Article VII.

                 Section 7.11.  Merger, Conversion, Consolidation or Succession
to Business.  Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder;
provided, however, that such corporation shall be otherwise qualified and
eligible under this Article VII, without the execution or filing of any paper
or any further act on the part of any of the parties hereto.  In case any
Certificates shall have been executed or authenticated, but not delivered, by
the Trustee then in office, any successor by merger, conversion or
consolidation to such authenticating Trustee may adopt such execution or
authentication and deliver the Certificates so executed or authenticated with
the same effect as if such successor Trustee had itself executed or
authenticated such Certificates.

                 Section 7.12.  Maintenance of Agencies.  (a)  With respect to
each series of Certificates, there shall at all times be maintained an office
or agency in the location set forth in Section 12.04 where Certificates may be
presented or surrendered for registration of transfer or for exchange, and for
payment thereof, and where notices and demands, to or upon the Trustee in
respect of such Certificates or this Agreement may be served; provided,
however, that, if it shall be necessary that the Trustee maintain an office or
agency in another location with respect to the Certificates (e.g., the
Certificates shall be represented by Definitive Certificates and shall be
listed on a national securities exchange), the Trustee will make all reasonable
efforts to establish such an office or agency.  Written notice of the location
of each such other office or agency and of any change of location thereof shall
be given by the Trustee to the Company, any Owner Trustees, the Loan Trustees
(in the case of
<PAGE>   56
                                       50

any Owner Trustee or Loan Trustee, at its address specified in the Note
Documents or such other address as may be notified to the Trustee) and the
Certificateholders.  In the event that no such office or agency shall be
maintained or no such notice of location or of change of location shall be
given, presentations and demands may be made and notices may be served at the
Corporate Trust Office of the Trustee.

                 (b)      There shall at all times be a Registrar and a Paying
Agent hereunder with respect to the Certificates.  Each such Authorized Agent
shall be a bank or trust company, shall be a corporation organized and doing
business under the laws of the United States or any state, with a combined
capital and surplus of at least $75,000,000, or a corporation having a combined
capital and surplus in excess of $5,000,000, the obligations of which are
guaranteed by a corporation organized and doing business under the laws of the
United States or any state, with a combined capital and surplus of at least
$75,000,000, and shall be authorized under such laws to exercise corporate
trust powers, subject to supervision by federal or state authorities.  The
Trustee shall initially be the Paying Agent and, as provided in Section 3.04,
Registrar hereunder with respect to the Certificates.  Each Registrar shall
furnish to the Trustee, at stated intervals of not more than six months, and at
such other times as the Trustee may request in writing, a copy of the Register
maintained by such Registrar.

                 (c)      Any corporation into which any Authorized Agent may
be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, consolidation or conversion to which any Authorized
Agent shall be a party, or any corporation succeeding to the corporate trust
business of any Authorized Agent, shall be the successor of such Authorized
Agent, if such successor corporation is otherwise eligible under this Section
7.12, without the execution or filing of any paper or any further act on the
part of the parties hereto or such Authorized Agent or such successor
corporation.

                 (d)      Any Authorized Agent may at any time resign by giving
written notice of resignation to the Trustee, the Company, any Owner Trustees
and the Loan Trustees.  The Company may, and at the request of the Trustee
shall, at any time terminate the agency of any Authorized Agent by giving
written notice of termination to such Authorized Agent and to the Trustee.
Upon the resignation or termination of an Authorized Agent or in case at any
time any such Authorized Agent shall cease to be eligible under this Section
7.12 (when, in either case, no other Authorized Agent performing the functions
of such Authorized Agent shall have been appointed), the Company shall promptly

Trust.  All moneys deposited with any Paying Agent for the purpose of any
payment on Certificates shall be deposited and held in trust for the benefit of
the Certificateholders entitled to such payment, subject to the provisions of

                 The Trustee may at any time, for the purpose of obtaining the
satisfaction and discharge of this Agreement or for any other purpose, direct
any Paying Agent to pay to the Trustee all sums held in trust by such Paying

which such sums were held by such Paying Agent; and, upon such payment by any
Paying Agent to the Trustee, such Paying Agent shall be released from all
further liability with respect to such money.

benefit of the Certificateholders, or, if not so held, the Trustee or its
nominee shall be reflected as the owner of such Equipment Notes or Permitted
Investments, as the case may be, in the register of the issuer of such
Equipment Notes or Permitted Investments, as the case may be.

Trustee hereby represents and warrants that:

                 (a)      the Trustee is a Delaware banking corporation

Trustee either (i) in its individual capacity and which is unrelated to the
transactions contemplated by this Agreement, the Intercreditor Agreement, the
Note Purchase Agreement or the Note Documents or (ii) as Trustee hereunder or

receives (directly or indirectly through the Subordination Agent) a request for
a consent to any amendment, modification, waiver or supplement under any

would require the consent of Certificateholders under Section 9.02 hereof, the
Trustee shall forthwith send a notice of such proposed amendment, modification,
waiver or supplement to each Certificateholder registered on the Register as of
the date of such notice.  The Trustee shall request from the Certificateholders
a Direction as to (a) whether or not to take or refrain from taking (or direct
the Subordination Agent to take or refrain from taking) any action which a
holder of (or, with respect to Postponed Notes, a prospective purchaser of)
such Equipment Note or a Controlling Party has the option to direct, (b)
whether or not to give or execute (or direct the Subordination Agent to give or
execute) any waivers, consents, amendments, modifications or supplements as a
holder of (or, with respect to Postponed Notes, a prospective purchaser of)
such Equipment Note or as Controlling Party and (c) how to vote (or direct the
Subordination Agent to vote) any Equipment Note (or, with respect to a
Postponed Note, its commitment to acquire such Postponed Note) if a vote has
been called for with respect thereto.  Provided such a request for
Certificateholder Direction shall have been made, in directing any action or
casting any vote or giving any consent as the holder of any Equipment Note (or
in directing the Subordination Agent in any of the foregoing), (i) other than
as Controlling Party, the Trustee shall vote for or give consent to any such
action with respect to such Equipment Note (or Postponed Note) in the same
proportion as that of (A) the aggregate face amounts of all Certificates
actually voted in favor of or for giving consent to such action by such
Direction of Certificateholders to (B) the aggregate face amount of all
Outstanding Certificates and (ii) as Controlling Party, the Trustee shall vote
as directed in such Certificateholder Direction by the Certificateholders
evidencing a Fractional Undivided Interest aggregating not less than a majority
in interest in the Trust.  For purposes of the immediately preceding sentence,
a Certificate shall have been "actually voted" if the Holder of such
Certificate has delivered to the Trustee an instrument evidencing such Holder's
consent to such Direction prior to one Business Day before the Trustee directs
such action or casts such vote or gives such consent.  Notwithstanding the
foregoing, but subject to Section 6.04 and any Intercreditor Agreement, the
Trustee may, with respect to the Certificates, in its own discretion and at its
own direction, consent and notify the relevant Loan Trustee of such consent (or
direct the Subordination Agent to consent and notify the Loan Trustee of such
consent) to any amendment, modification, waiver or supplement under any related
Indenture or any other related Note Document if an Event of Default hereunder

shall have occurred and be continuing or if such amendment, modification,
waiver or supplement will not materially adversely affect the interests of the
Certificateholders.

                 transactions contemplated to be consummated thereunder on the
                 date thereof, will violate any law or governmental rule or
                 regulation of the State of New York or the United States of
                 America known to such counsel to be applicable to the

thereto, the Trust shall be terminated, the Certificateholders shall receive
beneficial interests in the Related Trust in exchange for their interests in
the Trust equal to their respective beneficial interests in the Trust, and the
Outstanding Certificates representing Fractional Undivided Interests in the

Through Trust Agreement, without further signature or action of any party or
Certificateholder, to be certificates representing the same fractional
undivided interests in the Related Trust and its trust property.  By acceptance
of its Certificate, each Certificateholder consents to such assignment,
transfer and delivery of the Trust Property to the trustee of the Related Trust
upon the execution and delivery of the Assignment and Assumption Agreement.

at the time such notice is given to Certificateholders.  Upon presentation and
surrender of the Certificates in accordance with such notice, the Trustee shall
cause to be distributed to Certificateholders such final payments.

                 In the event that all of the Certificateholders shall not
surrender their Certificates for cancellation within six months after the date
specified in the above-mentioned written notice, the Trustee shall give a
second written notice to the remaining Certificateholders to surrender their
Certificates for cancellation and receive the final distribution with respect
thereto.  No additional interest shall accrue on the Certificates after the
Distribution Date specified in the first written notice.  In the event that any
money held by the Trustee for the payment of distributions on the Certificates
shall remain unclaimed for two years (or such lesser time as the Trustee shall
be satisfied, after sixty days' notice from the Company, is one month prior to
the escheat period provided under applicable law) after the final distribution
date with respect thereto, the Trustee shall pay to each Loan Trustee the
appropriate amount of money relating to such Loan Trustee and shall give
written notice thereof to the related Owner Trustees, the Owner Participants
and the Company.

                 The Certificates do not represent a direct obligation of, or
an obligation guaranteed by, or an interest in, the Company or the Trustee or
any of their affiliates.  The Certificates are limited in right of payment, all
as more specifically set forth on the face hereof and in the Agreement.  All
payments or distributions made to Certificateholders under the Agreement shall
be made only from the Trust Property and only to the extent that the Trustee
shall have sufficient income or proceeds from the Trust Property to make such
payments in accordance with the terms of the Agreement.  Each Certificateholder
of this Certificate, by its acceptance hereof, agrees that it will look solely
to the income and proceeds from the Trust Property to the extent available for
distribution to such Certificateholder as provided in the Agreement.  This
Certificate does not purport to summarize the Agreement and reference is made
to the Agreement for information with respect to the interests, rights,
benefits, obligations, proceeds, and duties evidenced hereby.  A copy of the
Agreement may be examined during normal business hours at the principal office
of the Trustee, and at such other places, if any, designated by the Trustee, by
any Certificateholder upon request.

                 The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Certificateholders under the
Agreement at any time by the Company and the Trustee with the consent of the
Certificateholders holding Certificates evidencing Fractional Undivided
Interests aggregating not less than a majority in interest in the Trust.  Any
such consent by the Certificateholder of this Certificate shall be conclusive
and binding on such Certificateholder and upon all future Certificateholders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange hereof or in lieu hereof whether or not notation of such consent is
made upon this Certificate.  The Agreement also permits the amendment thereof,
in certain limited circumstances, without the consent of the Certificateholders
of any of the Certificates.

                 As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Register upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee in its capacity as
Registrar, or by any successor Registrar, in the Borough of Manhattan, the City
of New York, duly endorsed or accompanied by a written instrument of transfer
in form satisfactory to the Trustee and the Registrar duly executed by the
Certificateholder hereof or such Certificateholder's attorney duly authorized
in writing, and thereupon one or more new Certificates of authorized
denominations evidencing the same aggregate Fractional Undivided Interest in
the Trust will be issued to the designated transferee or transferees.
<PAGE>   81
                                      A-9

                 The Certificates are issuable only as registered Certificates
without coupons in minimum denominations of [$100,000]* [$1,000]** Fractional
Undivided Interest and integral multiples of $1,000 in excess thereof [except
that one Certificate may be in a denomination of less than $100,000]*.  As
provided in the Agreement and subject to certain limitations therein set forth,
the Certificates are exchangeable for new Certificates of authorized
denominations evidencing the same aggregate Fractional Undivided Interest in
the Trust, as requested by the Certificateholder surrendering the same.

                 No service charge will be made for any such registration of
transfer or exchange, but the Trustee shall require payment by the Holder of a
sum sufficient to cover any tax or governmental charge payable in connection
therewith.

                 The Trustee, the Registrar, and any agent of the Trustee or
the Registrar may treat the person in whose name this Certificate is registered
as the owner hereof for all purposes, and neither the Trustee, the Registrar,
nor any such agent shall be affected by any notice to the contrary.

                 The obligations and responsibilities created by the Agreement
and the Trust created thereby shall terminate upon the distribution to
Certificateholders of all amounts required to be distributed to them pursuant
to the Agreement and the disposition of all property held as part of the Trust
Property.

Sirs:

                 In connection with our proposed sale of $_______ Fractional
Undivided Interest of the Certificates, we confirm that such sale has been
effected pursuant to and in accordance with Regulation S under the Securities
Act of 1933, as amended, and, accordingly, we represent that:

                 (1)      the offer of the Certificates was not made to a
         person in the United States;

                 (2)      either (a) at the time the buy order was originated,
         the transferee was outside the United States or we and any person
         acting on our behalf reasonably believed that the transferee was
         outside the United States or (b) the transaction was executed in, on
         or through the facilities of a designated off-shore securities market
         and neither we nor any person acting on our behalf knows that the
         transaction has been pre- arranged with a buyer in the United States;

                 (3)      no directed selling efforts have been made in the
         United States in contravention of the requirements of Rule 903(b) or
         Rule 904(b) of Regulation S, as applicable; and
<PAGE>   86
                                      C-2


                 (4)      the transaction is not part of a plan or scheme to
         evade the registration requirements of the Securities Act.

                 In addition, if the sale is made during a restricted period
and the provisions of Rule 903(c)(3) or Rule 904(c)(1) of Regulation S are
applicable thereto, we confirm that such sale has been made in accordance with

                          1998-1A (the "Certificates")

Dear Sirs:

                 In connection with our proposed purchase of $_______________
aggregate principal amount of the Certificates, we confirm that:

                 1.       We understand that any subsequent transfer of the
         Certificates is subject to certain restrictions and conditions set
         forth in the Pass Through Trust Agreement dated as of February 9, 1998
         relating to the Certificates (the "Pass Through Trust Agreement") and
         the undersigned agrees to be bound by, and not to resell, pledge or
         otherwise transfer the Certificates except in compliance with, such
         restrictions and conditions and the Securities Act of 1933, as amended
         (the "Securities Act").

                 2.       We understand that the Certificates have not been
         registered under the Securities Act, and that the Certificates may not
         be offered or sold except as permitted in the following sentence.  We
         agree, on our own behalf and on behalf of any accounts for which we
         are acting as hereinafter stated, that if we should sell any
         Certificate, we will do so only (A) in accordance with Rule 144A under
         the Securities Act to a "qualified institutional buyer" (as defined
         therein), (B) to an institutional "accredited investor" (as defined
         below) that, prior to such transfer, furnishes to you and Continental
         Airlines, Inc., a signed letter substantially in the form of this
         letter, (C) outside the United States in accordance with Rule 904 of
         Regulation S under the Securities Act, (D) pursuant to the exemption
         from registration provided by Rule 144 under the Securities Act, or
         (E) pursuant to an effective registration statement under
<PAGE>   88
                                      D-2

         the Securities Act, and we further agree to provide to any person
         purchasing any of the Certificates from us a notice advising such
         purchaser that resales of the Notes are restricted as stated herein.
         We further understand that the Certificates purchased by us will bear
         a legend to the foregoing effect.

                 3.       We understand that, on any proposed resale of any
         Certificates, we will be required to furnish to you and Atlas Air,
         Inc. such certifications, legal opinions and other information as you
         and Atlas Air, Inc.  may reasonably require to confirm that the
         proposed sale complies with the foregoing restrictions.  We further
         understand that the Certificates purchased by us will bear a legend to
         the foregoing effect.

                 4.       We are an institutional "accredited investor" (as
         defined in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the
         Securities Act) and have such knowledge and experience in financial
         and business matters as to be capable of evaluating the merits and
         risks of our investment in the Certificates and we and any accounts
         for which we are acting are each able to bear the economic risk of our
         or its investment.

                 5.       We are acquiring the Certificates purchased by us for
         our own account or for one or more accounts (each of which is an
         institutional "accredited investor") as to each of which we exercise
         sole investment discretion.

                 You and Atlas Air, Inc. are entitled to rely upon this letter
and are irrevocably authorized to produce this letter or a copy hereof to any
interested party in any administrative or legal proceedings or official inquiry

                 WHEREAS, the parties hereto desire to effect on the date
hereof (the "Transfer Date") (a) the transfer by the Assignor to the Assignee
of all of the right, title and interest of the Assignor in, under and with
respect to, among other things, the Trust Property and each of the documents

                 2.       Assumption.  The Assignee hereby assumes for the

confirms that it shall be deemed a party to each of the Assigned Documents to
which the Assignor is a party and shall be bound by all the terms thereof
(including the agreements and obligations of the Assignor set forth therein) as

benefit of the Assignor and the Beneficiaries all of the duties and obligations
of the Assignor under the Outstanding Applicable Certificates and hereby

or for the benefit of the Assignor that, under Section 1 hereof, belong to the
Assignee.

                 5.       Further Assurances.  The Assignor shall, at any time
and from time to time, upon the request of the Assignee, promptly and duly
execute and deliver any and all such further instruments and documents and take
such further action as the Assignee may reasonably request to obtain the full
benefits of this Assignment Agreement and of the right and powers herein
granted.  The Assignor agrees to deliver any Applicable Certificates, and all

Affiliate thereof shall be disregarded and deemed not to be Outstanding for
purposes of any such determination.  In determining whether the Trustee shall
be protected in relying upon any such Direction, only Certificates which the
Trustee knows to be so owned shall be so disregarded.  Notwithstanding the
foregoing, (i) if any such Person owns 100% of the Certificates Outstanding,
such Certificates shall not be so disregarded, and (ii) if any amount of
Certificates so owned by any such Person have been pledged in good faith, such
Certificates shall not be disregarded if the pledgee establishes to the
satisfaction of the Trustee the pledgee's right so to act with respect to such
Certificates and that the pledgee is not the Company or any Affiliate thereof.

                 (d)      The Company may, at its option, by delivery of an
Officer's Certificate to the Trustee, set a record date to determine the
Certificateholders in respect of the Certificates, entitled to give any
Direction.  Notwithstanding Section 316(c) of the Trust

Indenture Act, such record date shall be the record date specified in such
Officer's Certificate, which shall be a date not more than 30 days prior to the
first solicitation of Certificateholders of the applicable series in connection
therewith.  If such a record date is fixed, such Direction may be given before
or after such record date, but only the Certificateholders of record of the
applicable series at the close of business on such record date shall be deemed
to be Certificateholders for the purposes of determining whether
Certificateholders of the requisite proportion of Outstanding Certificates have
authorized or agreed or consented to such Direction, and for that purpose the
Outstanding Certificates shall be computed as of such record date; provided,
however, that no such Direction by the Certificateholders on such record date
shall be deemed effective unless it shall become effective pursuant to the
provisions of this Agreement not later than one year after such record date.

                 (e)      Any Direction by the Holder of any Certificate shall
bind the Holder of every Certificate issued upon the transfer thereof or in
exchange therefor or in lieu thereof, whether or not notation of such Direction
is made upon such Certificate.

                 (f)      Except as otherwise provided in Section 1.04(c),
Certificates owned by or pledged to any Person shall have an equal and
proportionate benefit under the provisions of this Agreement, without
preference, priority or distinction as among all of the Certificates.


                                   ARTICLE II

                       ACQUISITION OF THE TRUST PROPERTY

                 Section 2.01.    Acquisition of Trust Property.  The Trustee
is hereby irrevocably authorized and directed to execute and deliver the
Assignment and Assumption Agreement on the date specified in Section 11.01 of
the Related Pass Through Trust Agreement, subject only to the satisfaction of
the conditions set forth in said Section 11.01.  This Agreement (except only
for the immediately preceding sentence hereof, which is effective upon
execution and delivery hereof) shall become effective upon the execution and
delivery of the Assignment and Assumption Agreement by the Trustee and the
Related Trustee, automatically and without any further signature or action on
the part of the Company and the Trustee, and shall thereupon constitute the
legal, valid and binding obligation of the parties hereto enforceable against
each of the parties hereto in accordance with its terms.  Upon such execution
and delivery of the Assignment and Assumption Agreement, the Related Trust
shall be terminated, the Certificateholders shall receive beneficial interests
in the Trust in exchange for their interests in the Related Trust equal to
their respective beneficial interests in the Related Trust and the
"Outstanding" (as defined in the Related Pass Through Trust Agreement) pass
through certificates representing fractional undivided interests in the Related
Trust shall be deemed for all purposes of this Agreement,
<PAGE>   24
                                       18

without further signature or action of any party or Certificateholder, to be
Certificates representing the same Fractional Undivided Interests in the Trust
and Trust Property.  By acceptance of its Certificate, each Certificateholder
consents to and ratifies such assignment, transfer and delivery of the trust
property of the Related Trust to the Trustee upon the execution and delivery of
the Assignment and Assumption Agreement.

                 Section 2.02. [Intentionally omitted]

                 Section 2.03.  Acceptance by Trustee.  The Trustee, upon the
execution and delivery of the Assignment and Assumption Agreement, acknowledges
its acceptance of all right, title and interest in and to the Trust Property
and will hold such right, title and interest for the benefit of all then
present and future Certificateholders, upon the trusts herein set forth.  By
its payment for and acceptance of each Certificate issued under the Related
Pass Through Trust Agreement and deemed issued under this Agreement, each
Holder of such Certificate as grantor of such Trust thereby joins in the
creation and declaration of such Trust.

                 Section 2.04.  Limitation of Powers.  The Trust is constituted
solely for the purpose of making the investment in the Equipment Notes, and,
except as set forth herein, the Trustee shall not be authorized or empowered to
acquire any other investments or engage in any other activities and, in
particular, the Trustee shall not be authorized or empowered to do anything
that would cause such Trust to fail to qualify as a "grantor trust" for federal
income tax purposes (including, as subject to this restriction, acquiring any
Aircraft (as defined in the respective Indentures) by bidding such Equipment
Notes or otherwise, or taking any action with respect to any such Aircraft once
acquired).


                                  ARTICLE III

                                THE CERTIFICATES

                 Section 3.01.  Title, Form, Denomination and Execution of
Certificates.  (a)  The Initial Certificates shall be known as the "7.38%
1998-1A-S Initial Pass Through Certificates" and the Exchange Certificates
shall be known as the "7.38% 1998-1A-S Exchange Pass Through Certificates", in
each case, of the Trust.  Each Certificate will represent a fractional
undivided interest in the Trust and shall be substantially in the form set
forth as Exhibit A to the Related Pass Through Trust Agreement, with such
appropriate insertions, omissions, substitutions and other variations as are
required or permitted by the Related Pass Through Trust Agreement or by this
Agreement, as the case may be, or as the Trustee may deem appropriate, to
reflect the fact that the Certificates are being issued hereunder as opposed to
under the Related Pass Through Trust Agreement and may have such letters,
numbers or other marks of identification and such legends or endorsements
<PAGE>   25
                                       19

placed thereon as may be required to comply with the rules of any securities
exchange or as may, consistently herewith, be determined by the officers
executing such Certificates, as evidenced by their execution of the
Certificates.  Any portion of the text of any Certificate may be set forth on
the reverse thereof, with an appropriate reference thereto on the face of the
Certificate.

                 (b)      The Initial Certificates shall be issued only in
fully registered form without coupons and only in denominations of $100,000 or
integral multiples of $1,000 in excess thereof, except that one Certificate may
be issued in a denomination of less than $100,000.  The Exchange Certificates
will be issued in denominations of $1,000 or integral multiples thereof.  Each
Certificate shall be dated the date of its authentication.  The aggregate
Fractional Undivided Interest of Certificates initially deemed issued hereunder
shall not at any time exceed the aggregate principal amount of "Outstanding"
pass through trust certificates representing fractional undivided interests in
the Related Trust on the Transfer Date.

                 (c)      Initial Certificates offered and sold in reliance on
Rule 144A shall be issued initially in the form of a single permanent global
Certificate in registered form, substantially in the form set forth as Exhibit
A to the Related Pass Through Trust Agreement (the "U.S. Global Certificate"),
duly executed and authenticated by the Trustee as hereinafter provided.  The
U.S. Global Certificate will be registered in the name of a nominee for the
Depositary and deposited with the Trustee, as custodian for the Depositary.
The aggregate principal amount of the U.S. Global Certificate may from time to
time be increased or decreased by adjustments made on the records of the
Depositary or its nominee, or of the Trustee, as custodian for the Depositary
or its nominee, as hereinafter provided.

                 (d)      Initial Certificates offered and sold in offshore
transactions in reliance on Regulation S shall be issued initially in the form
of a single temporary global Certificate in registered form, substantially in
the form set forth as Exhibit A to the Related Pass Through Trust Agreement
(the "Temporary Offshore Global Certificate") duly executed and authenticated
by the Trustee as hereinafter provided.  The Temporary Offshore Global
Certificates will be registered in the name of a nominee of the Depositary for
credit to the account of the Agent Members acting as depositaries for Euroclear
and Cedel and deposited with the Trustee as custodian for the Depositary.  At
any time following March 21, 1998 (the "Offshore Certificates Exchange Date"),
upon receipt by the Trustee of a certificate substantially in the form of
Exhibit B to the Related Pass Through Trust Agreement, a single permanent
global Certificate in registered form substantially in the form set forth in
Exhibit A (the "Permanent Offshore Global Certificate"; and together with the
Temporary Offshore Global Certificate, the "Offshore Global Certificates"),
duly executed and authenticated by the Trustee as hereinafter provided, shall
be registered in the name of a nominee for the Depositary and deposited with
the Trustee, as custodian for the Depositary, and the Registrar shall reflect
on its books and records the date of such transfer and a decrease in the
principal
<PAGE>   26
                                       20

amount of any Temporary Offshore Global Certificate in an amount equal to the
principal amount of the beneficial interest in such Temporary Offshore Global
Certificate transferred.  The U.S. Global Certificate and the Offshore Global
Certificates are sometimes referred to as the "Global Certificates".

                 (e)      Initial Certificates offered and sold to
Institutional Accredited Investors shall be issued in the form of permanent
certificated Certificates in registered form in substantially the form set
forth as Exhibit A to the Related Pass Through Trust Agreement (the "U.S.
Physical Certificates").  Certificates issued pursuant to Section 3.05(b) in
exchange for interests in any Offshore Global Certificate shall be in the form
of permanent certificated Certificates in registered form substantially in the
form set forth in Exhibit A (the "Offshore Physical Certificates").  The
Offshore Physical Certificates and U.S. Physical Certificates are sometimes
collectively herein referred to as the "Physical Certificates".

                 (f)      The Exchange Certificates shall be issued in the form
of one or more global Certificates substantially in the form of Exhibit A to
the Related Pass Through Trust Agreement (each, a "Global Exchange
Certificate"), except that (i) the Private Placement Legend (hereinafter
defined) shall be omitted and (ii)  such Exchange Certificates shall contain
such appropriate insertions, omissions, substitutions and other variations from
the form set forth in Exhibit A to the Related Pass Through Trust Agreement
relating to the nature of the Exchange Certificates as the Responsible Officer
of the Trustee executing such Exchange Certificates on behalf of the Trust may
determine, as evidenced by such officer's execution on behalf of the Trust of
such Exchange Certificates.  Such Global Exchange Certificates shall be in
registered form and be registered in the name of DTC and deposited with the
Trustee, at its Corporate Trust Office, as custodian for DTC.  The aggregate
principal amount of any Global Exchange Certificate may from time to time be
increased or decreased by adjustments made on the records of the Trustee, as
custodian for DTC for such Global Exchange Certificate, which adjustments shall
be conclusive as to the aggregate principal amount of any such Global Exchange
Certificate.  Subject to clause (i) and (ii)  of the first sentence of this
Section 3.01(f), the terms hereof applicable to Restricted Global Certificates
and/or Global Certificates shall apply to the Global Exchange Certificates,
mutatis mutandis.

                 (g)      The definitive Certificates shall be in registered
form and shall be typed, printed, lithographed or engraved or produced by any
combination of these methods or may be produced in any other manner, all as
determined by the officers executing such Certificates, as evidenced by their
execution of such Certificates.

                 Section 3.02.  Restrictive Legends.  (a)  Subject to Section
3.06, unless and until (i) an Initial Certificate is sold under an effective
Registration Statement or (ii) an Initial Certificate is exchanged for an
Exchange Certificate pursuant to an effective Exchange Offer Registration
Statement, in each case as provided for in the Registration Rights Agreement,
<PAGE>   27
                                       21

each Global Certificate (other than the Permanent Offshore Global Certificate)
and each U.S. Physical Certificate shall bear the following legend (the
"Private Placement Legend") on the face thereof:

                 THIS CERTIFICATE HAS NOT BEEN REGISTERED UNDER THE U.S.
         SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND
         ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR
         TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY PERSONS EXCEPT AS SET FORTH
         IN THE FOLLOWING SENTENCE.  BY ITS ACQUISITION HEREOF, THE HOLDER (1)
         REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS
         DEFINED IN RULE 144A UNDER THE SECURITIES ACT), (B) IT IS AN
         INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)(1),
         (2), (3) OR (7) OF REGULATION D UNDER THE SECURITIES ACT) (AN
         "INSTITUTIONAL ACCREDITED INVESTOR") OR (C) IT IS NOT A U.S.  PERSON
         AND IS ACQUIRING THIS CERTIFICATE IN AN OFFSHORE TRANSACTION IN
         COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT; (2) AGREES THAT
         IT WILL NOT WITHIN TWO YEARS AFTER THE LATER OF THE ORIGINAL ISSUANCE
         OF THIS CERTIFICATE OR THE LAST DATE ON WHICH THIS CERTIFICATE WAS
         HELD BY ATLAS AIR, INC., THE TRUSTEE OR ANY AFFILIATE OF ANY OF SUCH
         PERSONS RESELL OR OTHERWISE TRANSFER THIS CERTIFICATE EXCEPT (A) TO A
         QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE
         SECURITIES ACT, (B) INSIDE THE UNITED STATES TO AN INSTITUTIONAL
         ACCREDITED INVESTOR ACQUIRING $100,000 OR MORE AGGREGATE PRINCIPAL
         AMOUNT OF  SUCH CERTIFICATE THAT, PRIOR TO SUCH TRANSFER, FURNISHES TO
         THE TRUSTEE A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND
         AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THIS
         CERTIFICATE (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM THE
         TRUSTEE), (C) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN
         COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT, (D) PURSUANT TO THE
         EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES
         ACT (IF AVAILABLE) OR (E) PURSUANT TO AN EFFECTIVE REGISTRATION
         STATEMENT UNDER THE SECURITIES ACT; AND (3) AGREES THAT IT WILL
         DELIVER TO EACH PERSON TO WHOM THIS CERTIFICATE IS TRANSFERRED A
         NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.  IN CONNECTION WITH
         ANY TRANSFER OF THIS CERTIFICATE WITHIN TWO YEARS AFTER THE LATER OF
         THE ORIGINAL ISSUANCE OF THIS CERTIFICATE OR THE LAST DATE ON WHICH
         THIS CERTIFICATE WAS HELD BY ATLAS AIR,
<PAGE>   28
                                       22

         INC., THE TRUSTEE OR ANY AFFILIATE OF ANY OF SUCH PERSONS THE HOLDER
         MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF
         RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO
         THE TRUSTEE.  AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION",
         "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM BY
         REGULATION S UNDER THE SECURITIES ACT.  THE PASS THROUGH TRUST
         AGREEMENT CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO
         REGISTER ANY TRANSFER OF THIS CERTIFICATE IN VIOLATION OF THE
         FOREGOING RESTRICTIONS.

                 (b)      Each Global Certificate shall also bear the following
legend on the face thereof:

         UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE
         OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO
         THE TRUSTEE OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR
         PAYMENT, AND ANY CERTIFICATE ISSUED IN EXCHANGE FOR THIS CERTIFICATE
         IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS
         REQUESTED BY AN AUTHORIZED  REPRESENTATIVE OF DTC (AND ANY PAYMENT
         HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED
         BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER
         USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL
         INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
         HEREIN.

         TRANSFERS OF THIS GLOBAL CERTIFICATE SHALL BE LIMITED TO TRANSFERS IN
         WHOLE, BUT NOT IN PART, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF
         OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL
         CERTIFICATE SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE
         RESTRICTIONS SET FORTH IN SECTIONS 3.05 AND 3.06 OF THE PASS THROUGH
         TRUST AGREEMENT REFERRED TO HEREIN.

                 Section 3.03.  Authentication of Certificates.  (a)  
[Intentionally omitted]

                 (b)      No Certificate shall be entitled to any benefit under
this Agreement or be valid or obligatory for any purpose, unless there appears
on such Certificate a certificate of authentication substantially in the form
provided for herein executed by the Related Trustee or by the Trustee by the
manual signature of one of its authorized signatories, and
<PAGE>   29
                                       23

such certificate upon any Certificate shall be conclusive evidence, and the
only evidence, that such Certificate has been duly authenticated and delivered
hereunder.

                 Section 3.04.  Transfer and Exchange.  The Trustee shall cause
to be kept at the office or agency to be maintained by it in accordance with
the provisions of Section 7.12 of this Agreement a register (the "Register")
for the Certificates in which, subject to such reasonable regulations as it may
prescribe, the Trustee shall provide for the registration of the Certificates
and of transfers and exchanges of the Certificates as herein provided.  The
Trustee shall initially be the registrar (the "Registrar") for the purpose of
registering the Certificates and transfers and exchanges of the Certificates as
herein provided.  A Certificateholder may transfer a Certificate by written
application to the Registrar stating the name of the proposed transferee and
otherwise complying with the terms of this Agreement, including providing a
written certificate or other evidence of compliance with any restrictions on
transfer.  No such transfer shall be effected until, and such transferee shall
succeed to the rights of a Certificateholder only upon, final acceptance and
registration of the transfer by the Registrar in the Register.  Prior to the
registration of any transfer by a Certificateholder as provided herein, the
Trustee shall treat the person in whose name the Certificate is registered as
the owner thereof for all purposes, and the Trustee shall not be affected by
notice to the contrary.  Furthermore, the Depositary shall, by acceptance of a
Global Certificate, agree that transfers of beneficial interests in such Global
Certificate may be effected only through a book-entry system maintained by the
Depositary (or its agent), and that ownership of a beneficial interest in the
Certificate shall be required to be reflected in a book entry.  When
Certificates are presented to the Registrar with a request to register the
transfer or to exchange them for an equal face amount of Certificates of other
authorized denominations, the Registrar shall register the transfer or make the
exchange as requested if its requirements for such transactions are met.  To
permit registrations of transfers and exchanges in accordance with the terms,
conditions and restrictions hereof, the Trustee shall execute and authenticate
Certificates at the Registrar's request.  No service charge shall be made for
any registration of transfer or exchange of the Certificates, but the Trustee
may require payment by the transferor 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 charges payable upon
exchanges pursuant to Section 3.10 or 9.07).

                 Section 3.05.  Book-Entry Provisions for U.S. Global
Certificate and Offshore Global Certificates.  (a) Members of, or participants
in, the Depositary ("Agent Members") shall have no rights under this Agreement
with respect to any Global Certificate held on their behalf by the Depositary,
or the Trustee as its custodian, and the Depositary may be treated by the
Trustee and any agent of the Trustee as the absolute owner of such Global
Certificate for all purposes whatsoever.  Notwithstanding the foregoing,
nothing herein shall prevent the Trustee or any agent of the Trustee from
giving effect to any written certification, proxy or other authorization
furnished by the Depositary or shall impair, as between the Depositary
<PAGE>   30
                                       24

and its Agent Members, the operation of customary practices governing the
exercise of the rights of a holder of any Certificate.  Upon the issuance of
any Global Certificate, the Registrar or its duly appointed agent shall record
a nominee of the Depositary as the registered holder of such Global
Certificate.

                 (b)      Transfers of any Global Certificate shall be limited
to transfers of such Global Certificate or Offshore Global Certificate in
whole, but not in part, to nominees of the Depositary, its successor or such
successor's nominees.  Beneficial interests in the U.S. Global Certificate and
any Offshore Global Certificate may be transferred in accordance with the rules
and procedures of the Depositary and the provisions of Section 3.06.
Beneficial interests in the U.S. Global Certificate or an Offshore Global
Certificate shall be delivered to all beneficial owners in the form of U.S.
Physical Certificates or Offshore Physical Certificates, as the case may be, if
(i) the Depositary notifies the Trustee that it is unwilling or unable to
continue as Depositary for the U.S. Global Certificate or such Offshore Global
Certificate, as the case may be, and a successor depositary is not appointed by
the Trustee within 90 days of such notice or (ii) an Event of Default has
occurred and is continuing and the Registrar has received a request from the
Depositary to issue Physical Certificates.

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

                 (d)      In connection with the transfer of the entire U.S.
Global Certificate or an entire Offshore Global Certificate to the beneficial
owners thereof pursuant to paragraph (b) of this Section 3.05, such U.S. Global
Certificate or Offshore Global Certificate, as the case may be, shall be deemed
to be surrendered to the Trustee for cancellation, and the Trustee shall
execute, authenticate and deliver, to each beneficial owner identified by the
Depositary in exchange for its beneficial interest in such U.S. Global
Certificate or Offshore Global Certificate, as the case may be, an equal
aggregate principal amount of U.S. Physical Certificates or Offshore Physical
Certificates, as the case may be, of authorized denominations.

                 (e)      Any U.S. Physical Certificate delivered in exchange
for an interest in the U.S. Global Certificate pursuant to paragraph (b) of
this Section 3.05 shall, except as otherwise provided by paragraph (f) of
Section 3.06, bear the Private Placement Legend.

                 (f)      Any Offshore Physical Certificate delivered in
exchange for an interest in an Offshore Global Certificate pursuant to
paragraph (b) of this Section shall, except as
<PAGE>   31
                                       25

otherwise provided by paragraph (f) of Section 3.06, bear the applicable legend
regarding transfer restrictions set forth in Section 3.02(a).

                 (g)      The registered holder of the U.S. Global Certificate
or any Offshore Global Certificate 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
Agreement or the Certificates.

                 Section 3.06.  Special Transfer Provisions.  Unless and until
(i) an Initial Certificate is sold under an effective Registration Statement,
or (ii) an Initial Certificate is exchanged for an Exchange Certificate
pursuant to an effective Exchange Offer Registration Statement, in each case
pursuant to the Registration Rights Agreement, the following provisions shall
apply to such Initial Certificates:

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

                          (i)     The Registrar shall register the transfer of
                 any Certificate, whether or not such Certificate bears the
                 Private Placement Legend, if (x) the requested transfer is at
                 least three years after the later of the original issue date
                 of the Certificates and the last date on which such
                 Certificate was held by the Company or any affiliate of any
                 such persons or (y) the proposed transferee has delivered to
                 the Registrar a letter substantially in the form of Exhibit D
                 to the Related Pass Through Trust Agreement and the aggregate
                 principal amount of the Certificates being transferred is at
                 least $100,000.

                          (ii)    If the proposed transferor is an Agent Member
                 holding a     beneficial interest in the U.S. Global
                 Certificate, 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 of the transfer and a decrease in
                 the principal amount of such U.S. Global Certificate in an
                 amount equal to the principal amount of the beneficial
                 interest in such U.S. Global Certificate to be transferred,
                 and the Company shall execute, and the Trustee shall
                 authenticate and deliver to the transferor or at its
                 direction, one or more U.S. Physical Certificates of like
                 tenor and amount.

                 (b)      Transfers to QIBs.  The following provisions shall
         apply with respect to the registration of any proposed transfer of an
         Initial Certificate to a QIB (excluding Non-U.S. Persons):
<PAGE>   32
                                       26


                          (i)     If the Certificate to be transferred consists
                 of U.S. Physical  Certificates or an interest in any Temporary
                 Offshore Global Certificate, 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
                 Initial Certificate stating, or has otherwise advised the
                 Trustee 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 Initial Certificate stating, or has otherwise
                 advised the Trustee and the Registrar in writing, that it is
                 purchasing the Initial Certificate for its own account or an
                 account with respect to which it exercises sole investment
                 discretion and that it, or the Person on whose behalf it is
                 acting with respect to 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 Trust and/or 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.

                          (ii)    Upon receipt by the Registrar of the
                 documents referred to in clause (i) above and instructions
                 given in accordance with the Depositary's and the Registrar's
                 procedures therefor, the Registrar shall reflect on its books
                 and records the date of such transfer and an increase in the
                 principal amount of the U.S. Global Certificate in an amount
                 equal to the principal amount of the U.S.  Physical
                 Certificates or interests in the Temporary Offshore Global
                 Certificate, as the case may be, being transferred, and the
                 Trustee shall cancel such Physical Certificates or decrease
                 the amount of such Temporary Offshore Global Certificate so
                 transferred.

                 (c)      Transfers of Interests in the Permanent Offshore
         Global Certificate or Offshore Physical Certificates.  The Registrar
         shall register any transfer of interests in the Permanent Offshore
         Global Certificate or Offshore Physical Certificates without requiring
         any additional certification.

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

                          (i)     Prior to the Offshore Certificates Exchange
                 Date, the Registrar shall register any proposed transfer of an
                 Initial Certificate to a Non-U.S. Person upon receipt of a
                 certificate substantially in the form set forth as Exhibit C
                 to the Related Pass Through Trust Agreement from the proposed
                 transferor.
<PAGE>   33
                                       27

                          (ii)    On and after the Offshore Certificates
                 Exchange Date, the Registrar shall register any proposed
                 transfer to any Non-U.S. Person if the Certificate to be
                 transferred is a U.S. Physical Certificate or an interest in
                 the U.S. Global Certificate, upon receipt of a certificate
                 substantially in the form of Exhibit C from the proposed
                 transferor.  The Registrar shall promptly send a copy of such
                 certificate to the Company.

                          (iii)   Upon receipt by the Registrar of (x) the
                 documents, if any, required by paragraph (ii) 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 of such transfer and a decrease in
                 the principal amount of such U.S. Global Certificate in an
                 amount equal to the principal amount of the beneficial
                 interest in such U.S. Global Certificate to be transferred,
                 and (B) 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 Certificate in an amount equal to the
                 principal amount of the U.S. Physical Certificate or the U.S.
                 Global Certificate, as the case may be, to be transferred, and
                 the Trustee shall cancel the Physical Certificate, if any, so
                 transferred or decrease the amount of such U.S. Global
                 Certificate.

                 (e)      Private Placement Legend.  Upon the transfer,
         exchange or replacement of Certificates not bearing the Private
         Placement Legend, the Registrar shall deliver Certificates that do not
         bear the Private Placement Legend.  Upon the transfer, exchange or
         replacement of Certificates bearing the Private Placement Legend, the
         Registrar shall deliver only Certificates that bear the Private
         Placement Legend unless either (i) the circumstances contemplated by
         paragraph (a)(i)(x) or (e)(ii) of this Section 3.06 exist or (ii)
         there is delivered to the Registrar an Opinion of Counsel 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 Certificate
         bearing the Private Placement Legend, each Holder of such a
         Certificate acknowledges the restrictions on transfer of such
         Certificate set forth in this Agreement and agrees that it will
         transfer such Certificate only as provided in this Agreement.  The
         Registrar shall not register a transfer of any Certificate unless such
         transfer complies with the restrictions on transfer of such
         Certificate set forth in this Agreement.  In connection with any
         transfer of Certificates, each Certificateholder agrees by its
         acceptance of the Certificates to furnish the Registrar or the Trustee
         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,
<PAGE>   34
                                       28

         the registration requirements of the Securities Act; provided that the
         Registrar shall not be required to determine the sufficiency of any
         such certifications, legal opinions or other information.

                 Until such time as no Certificates remain Outstanding, the
Registrar shall retain copies of all letters, notices and other written
communications received pursuant to Section 3.05 or this Section 3.06.  The
Trustee, if not the Registrar at such time, 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 3.07.  Mutilated, Destroyed, Lost or Stolen
Certificates.  If (a) any mutilated Certificate is surrendered to the Registrar
or the Registrar receives evidence to its satisfaction of the destruction, loss
or theft of any Certificate and (b) there is delivered to the Registrar and the
Trustee such security, indemnity or bond, as may be required by them to save
each of them harmless, then, in the absence of notice to the Registrar or the
Trustee that such destroyed, lost or stolen Certificate has been acquired by a
bona fide purchaser, and provided that the requirements of Section 8-405 of the
Uniform Commercial Code in effect in any applicable jurisdiction are met, the
Trustee shall execute, authenticate and deliver, in exchange for or in lieu of
any such mutilated, destroyed, lost or stolen Certificate, a new Certificate or
Certificates, in authorized denominations and of like Fractional Undivided
Interest and bearing a number not contemporaneously outstanding.

                 In connection with the issuance of any new Certificate under
this Section 3.07, the Trustee may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Trustee
and the Registrar) connected therewith.

                 Any duplicate Certificate issued pursuant to this Section 3.07
shall constitute conclusive evidence of the appropriate Fractional Undivided
Interest in the Trust, as if originally issued, whether or not the lost, stolen
or destroyed Certificate shall be found at any time.

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

                 Section 3.08.  Persons Deemed Owners.  Prior to due
presentment of a Certificate for registration of transfer, the Trustee, the
Registrar and any Paying Agent may treat the Person in whose name any
Certificate is registered (as of the day of determination) as the owner of such
Certificate for the purpose of receiving distributions pursuant to Article
<PAGE>   35
                                       29

IV and for all other purposes whatsoever, and none of the Trustee, the
Registrar or any Paying Agent shall be affected by any notice to the contrary.

                 Section 3.09.  Cancellation.  All Certificates surrendered for
payment or transfer or exchange shall, if surrendered to the Trustee or any
agent of the Trustee other than the Registrar, be delivered to the Registrar
for cancellation and shall promptly be cancelled by it.  No Certificates shall
be authenticated in lieu of or in exchange for any Certificates cancelled as
provided in this Section, except as expressly permitted by this Agreement.  All
cancelled Certificates held by the Registrar shall be destroyed and a
certification of their destruction delivered to the Trustee.

                 Section 3.10.  Temporary Certificates.  Until definitive
Certificates are ready for delivery, the Trustee shall authenticate temporary
Certificates.  Temporary Certificates shall be substantially in the form of
definitive Certificates but may have insertions, substitutions, omissions and
other variations determined to be appropriate by the officers executing the
temporary Certificates, as evidenced by their execution of such temporary
Certificates.  If temporary Certificates are issued, the Trustee will cause
definitive Certificates to be prepared without unreasonable delay.  After the
preparation of definitive Certificates, the temporary Certificates shall be
exchangeable for definitive Certificates upon surrender of the temporary
Certificates at the office or agency of the Trustee designated for such purpose
pursuant to Section 7.12, without charge to the Certificateholder.  Upon
surrender for cancellation of any one or more temporary Certificates, the
Trustee shall execute, authenticate and deliver in exchange therefor a like
face amount of definitive Certificates of authorized denominations.  Until so
exchanged, the temporary Certificates shall be entitled to the same benefits
under this Agreement as definitive Certificates.

                 Section 3.11.  Limitation of Liability for Payments.  All
payments and distributions made to Certificateholders shall be made only from
the Trust Property and only to the extent that the Trustee shall have
sufficient income or proceeds from the Trust Property to make such payments in
accordance with the terms of Article IV of this Agreement.  Each
Certificateholder, by its acceptance of a Certificate, agrees that it will look
solely to the income and proceeds from the Trust Property for any payment or
distribution due to such Certificateholder pursuant to the terms of this
Agreement and that it will not have any recourse to the Company, the Trustee,
the Loan Trustees, the Liquidity Providers, the Owner Trustees or the Owner
Participants, except as otherwise expressly provided herein or in the
Intercreditor Agreement.

                 The Company is a party to this Agreement solely for purposes
of meeting the requirements of the Trust Indenture Act, and therefore shall not
have any right, obligation or liability hereunder (except as otherwise
expressly provided herein).

                               CERTIFICATEHOLDERS

                 Section 4.01.  Certificate Account and Special Payments
Account.  (a)  The Trustee shall establish and maintain on behalf of the
Certificateholders a Certificate Account as one or more non-interest-bearing
accounts.  The Trustee shall hold such Certificate Account in trust for the
benefit of the Certificateholders, and shall make or permit withdrawals
therefrom only as provided in this Agreement.  On each day when a Scheduled
Payment is made to the Trustee under the Intercreditor Agreement with respect
to the Certificates, the Trustee, upon receipt thereof, shall immediately
deposit the aggregate amount of such Scheduled Payment in such Certificate
Account.

                 (b)      The Trustee shall establish and maintain on behalf of
the Certificateholders a Special Payments Account as one or more accounts,
which shall be non-interest bearing except as provided in Section 4.04. The
Trustee shall hold the Special Payments Account in trust for the benefit of the
Certificateholders and shall make or permit withdrawals therefrom only as
provided in this Agreement.  On each day when one or more Special Payments are
made to the Trustee under the Intercreditor Agreement and upon payment of the
Special Redemption Premium to the Trustee under the Note Purchase Agreement
with respect to the Certificates, the Trustee, upon receipt thereof, shall
immediately deposit the aggregate amount of such Special Payments in such
Special Payments Account.

                 (c)      The Trustee shall present (or, if applicable, cause
the Subordination Agent to present) to the related Loan Trustee of each
Equipment Note such Equipment Note on the date of its stated final maturity or,
in the case of any Equipment Note which is to be redeemed in whole pursuant to
the related Indenture, on the applicable redemption date under such Indenture.

                 Section 4.02.  Distributions from Certificate Account and
Special Payments Account.  (a)  On each Regular Distribution Date with respect
to a series of Certificates or as soon thereafter as the Trustee has confirmed
receipt of the payment of all or any part of the Scheduled Payments due on the
Equipment Notes held (subject to the Intercreditor Agreement) in the related
Trust on such date, the Trustee shall distribute out of the applicable
Certificate Account the entire amount deposited therein pursuant to Section
4.01(a).  There shall be so distributed to each Certificateholder of record of
such series on the Record Date with respect to such Regular Distribution Date
(other than as provided in Section 11.01 concerning the final distribution) by
check mailed to such Certificateholder, at the address appearing in the
Register, such Certificateholder's pro rata share (based on the Fractional
Undivided Interest in the Trust held by such Certificateholder)
<PAGE>   37
                                       31

of the total amount in the applicable Certificate Account, except that, with
respect to Certificates registered on the Record Date in the name of a Clearing
Agency (or its nominee), such distribution shall be made by wire transfer in
immediately available funds to the account designated by such Clearing Agency
(or such nominee).

                 (b)      On each Special Distribution Date with respect to any
Special Payment with respect to the Certificates or as soon thereafter as the
Trustee has confirmed receipt of any Special Payments due on the Equipment
Notes held (subject to the Intercreditor Agreement) in the related Trust or
realized upon the sale of such Equipment Notes or receipt of the Special
Redemption Premium, the Trustee shall distribute out of the applicable Special
Payments Account the entire amount of such applicable Special Payment deposited
therein pursuant to Section 4.01(b).  There shall be so distributed to each
Certificateholder of record of such series on the Record Date with respect to
such Special Distribution Date (other than as provided in Section 11.01
concerning the final distribution) by check mailed to such Certificateholder,
at the address appearing in the Register, such Certificateholder's pro rata
share (based on the Fractional Undivided Interest in the related Trust held by
such Certificateholder) of the total amount in the applicable Special Payments
Account on account of such Special Payment, except that, with respect to
Certificates registered on the Record Date in the name of a Clearing Agency (or
its nominee), such distribution shall be made by wire transfer in immediately
available funds to the account designated by such Clearing Agency (or such
nominee).

                 (c)      The Trustee shall, at the expense of the Company,
cause notice of each Special Payment with respect to a series of Certificates
to be mailed to each Certificateholder at his address as it appears in the
Register.  In the event of redemption or purchase of Equipment Notes held in
the related Trust, such notice shall be mailed not less than 15 days prior to
the Special Distribution Date for the Special Payment resulting from such
redemption or purchase, which Special Distribution Date shall be the date of
such redemption or purchase.  In the event that any Special Redemption Premium
is to be paid by the Company to the Trustee under the Note Purchase Agreement,
such notice shall be mailed, together with the notice by the Escrow Paying
Agent under Section 2.06 of the Escrow Agreement, not less than 20 days prior
to the Special Distribution Date for such amount, which Special Distribution
Date shall be the Final Withdrawal Date.  In the case of any other Special
Payments, such notice shall be mailed as soon as practicable after the Trustee
has confirmed that it has received funds for such Special Payment, stating the
Special Distribution Date for such Special Payment which shall occur not less
than 15 days after the date of such notice and as soon as practicable
thereafter.  Notices mailed by the Trustee shall set forth:

                 (i)      the Special Distribution Date and the Record Date
         therefor (except as otherwise provided in Section 11.01);
<PAGE>   38
                                       32

                 (ii)     the amount of the Special Payment for each $1,000
         face amount Certificate and the amount thereof constituting principal,
         premium, if any, and interest;

                 (iii)    the reason for the Special Payment; and

                 (iv)     if the Special Distribution Date is the same date as
         a Regular Distribution Date for the Certificates, the total amount to
         be received on such date for each $1,000 face amount Certificate.

If the amount of (i) premium, if any, payable upon the redemption or purchase
of an Equipment Note or (ii) the Special Redemption Premium, if any, has not
been calculated at the time that the Trustee mails notice of a Special Payment,
it shall be sufficient if the notice sets forth the other amounts to be
distributed and states that any premium received will also be distributed.

                 If any redemption of the Equipment Notes held in any Trust is
cancelled, the Trustee, as soon as possible after learning thereof, shall cause
notice thereof to be mailed to each Certificateholder at its address as it
appears on the Register.

                 Section 4.03.  Statements to Certificateholders.  (a)  On each
Regular Distribution Date and Special Distribution Date, the Trustee will
include with each distribution of a Scheduled Payment or Special Payment, as
the case may be, to Certificateholders a statement setting forth the
information provided below (in the case of a Special Payment, including any
Special Redemption Premium, reflecting in part the information provided by the
Escrow Paying Agent under the Escrow Agreement).  Such statement shall set
forth (per $1,000 aggregate principal amount of Certificate as to (ii), (iii),
(iv) and (v) below) the following information:

                 (i)      the aggregate amount of funds distributed on such
         Distribution Date under the Agreement and under the Escrow Agreement,
         indicating the amount allocable to each source;

                 (ii)     the amount of such distribution under this Agreement
         allocable to principal and the amount allocable to premium (including
         the Special Redemption Premium), if any;

                 (iii)    the amount of such distribution under this Agreement
         allocable to interest;

                 (iv)     the amount of such distribution under the Escrow
         Agreement allocable to interest;
<PAGE>   39
                                       33


                 (v)      the amount of such distribution under the Escrow
         Agreement allocable to Deposits; and

                 (vi)     the Pool Balance and the Pool Factor.

                 With respect to the Certificates registered in the name of a
Clearing Agency or its nominee, on the Record Date prior to each Distribution
Date, the Trustee will request from the Clearing Agency a securities position
listing setting forth the names of all Clearing Agency Participants reflected
on the Clearing Agency's books as holding interests in the Certificates on such
Record Date.  On each Distribution Date, the Trustee will mail to each such
Clearing Agency Participant the statement described above and will make
available additional copies as requested by such Clearing Agency Participant
for forwarding to holders of interests in the Certificates.

                 (b)      Within a reasonable period of time after the end of
each calendar year but not later than the latest date permitted by law, the
Trustee shall furnish to each Person who at any time during such calendar year
was a Certificateholder of record a statement containing the sum of the amounts
determined pursuant to clauses (a)(i), (a)(ii), (a)(iii), (a)(iv) and (a)(v)
above with respect to the related Trust for such calendar year or, in the event
such Person was a Certificateholder of record during a portion of such calendar
year, for the applicable portion of such year, and such other items as are
readily available to the Trustee and which a Certificateholder shall reasonably
request as necessary for the purpose of such Certificateholder's preparation of
its federal income tax returns.  Such statement and such other items shall be
prepared on the basis of information supplied to the Trustee by the Clearing
Agency Participants and shall be delivered by the Trustee to such Clearing
Agency Participants to be available for forwarding by such Clearing Agency
Participants to the holders of interests in the Certificates in the manner
described in Section 4.03(a).

                 (c)      Promptly following (i) the Transfer Date, if there
has been any change in the information set forth in clauses (x), (y) and (z)
below from that set forth in page 65 of the Offering Memorandum, and (ii) any
early redemption or purchase of, or any default in the payment of principal or
interest in respect of, any of the Equipment Notes held in the Trust, or any
Final Withdrawal, the Trustee shall furnish to Certificateholders of record on
such date a statement setting forth (x) the expected Pool Balances for each
subsequent Regular Distribution Date following the Transfer Date, (y) the
related Pool Factors for such Regular Distribution Dates and (z) the expected
principal distribution schedule of the Equipment Notes, in the aggregate, held
as Trust Property at the date of such notice.  With respect to the Certificates
registered in the name of a Clearing Agency, on the Transfer Date, the Trustee
will request from such Clearing Agency a securities position listing setting
forth the names of all Clearing Agency Participants reflected on such Clearing
Agency's books as holding interests in the Certificates on such date.  The
Trustee will mail to each such Clearing Agency Participant the statement
described above and will make available additional
<PAGE>   40
                                       34

copies as requested by such Clearing Agency Participant for forwarding to
holders of interests in the Certificates.

                 Section 4.04.  Investment of Special Payment Moneys.  Any
money received by the Trustee pursuant to Section 4.01(b) representing a
Special Payment which is not distributed on the date received shall, to the
extent practicable, be invested in Permitted Investments by the Trustee pending
distribution of such Special Payment pursuant to Section 4.02.  Any investment
made pursuant to this Section 4.04 shall be in such Permitted Investments
having maturities not later than the date that such moneys are required to be
used to make the payment required under Section 4.02 on the applicable Special
Distribution Date and the Trustee shall hold any such Permitted Investments
until maturity.  The Trustee shall have no liability with respect to any
investment made pursuant to this Section 4.04, other than by reason of the
willful misconduct or negligence of the Trustee.  All income and earnings from
such investments shall be distributed on such Special Distribution Date as part
of such Special Payment.

Company, at its own cost and expense, will do or cause to be done all things
necessary to preserve and keep in full force and effect its corporate

preservation thereof is no longer desirable in the conduct of the business of
the Company.

                 Section 5.02.  Consolidation, Merger, Etc.  The Company shall
not consolidate with or merge into any other corporation or convey, transfer or
lease substantially all of its assets as an entirety to any Person unless:

                 (a)      the corporation formed by such consolidation or into
         which the Company is merged or the Person that acquires by conveyance,
         transfer or lease substantially all of the assets of the Company as an

         of entitlement to the benefits of Section 1110 of the Bankruptcy
         Reform Act of 1978, as amended (11 U.S.C. Section  1110), with respect
         to the Leases or the Aircraft owned by the Company;

                                       35

                 (b)      the corporation formed by such consolidation or into
         which the Company is merged or the Person which acquires by
         conveyance, transfer or lease substantially all of the assets of the
         Company as an entirety shall execute and deliver to the Trustee
         applicable to the Certificates a duly authorized, valid, binding and
         enforceable agreement in form and substance reasonably satisfactory to
         the Trustee containing an assumption by such successor corporation or
         Person of the due and punctual performance and observance of each
         covenant and condition of the Note Documents and of this Agreement
         applicable to the Certificates to be performed or observed by the
         Company; and

                 (c)      the Company shall have delivered to the Trustee an
         Officer's Certificate of the Company and an Opinion of Counsel of the
         Company reasonably satisfactory to the Trustee, each stating that such

or lease of substantially all of the assets of the Company as an entirety in
accordance with this Section 5.02, the successor corporation or Person formed
by such consolidation or into which the Company is merged or to which such
conveyance, transfer or lease is made shall succeed to, and be substituted for,
and may exercise every right and power of, the Company under this Agreement
applicable to the Certificates with the same effect as if such successor
corporation or Person had been named as the Company herein.  No such
conveyance, transfer or lease of substantially all of the assets of the Company
as an entirety shall have the effect of releasing any successor corporation or
Person which shall have become such in the manner prescribed in this Section
5.02 from its liability in respect of this Agreement and any Note Document
applicable to the Certificates to which it is a party.

         to purchase all, but not less than all, of the Certificates upon ten
         days' written notice to the Trustee and each other Class B
         Certificateholder, provided that (A) if prior to the end of such
         ten-day period any other Class B Certificateholder notifies such

         Certificateholder to purchase all, but not less than all, of the
         Certificates pro rata based on the Fractional Undivided Interest in

         Certificates and the Class B Certificates upon ten days' written
         notice to the Trustee, the Class B Trustee and each other Class C

         period any other Class C Certificateholder fails to notify the

         such other Class C Certificateholder shall lose its right to purchase
         the Certificates pursuant to this Section 6.01(b); and

                 (iii)    each Class D Certificateholder shall have the right
         (which shall not expire upon any purchase of the Certificates pursuant
         to clause (i) or (ii) above) to purchase all, but not less than all,

         participate in such purchase, then such other Class D
         Certificateholder may
<PAGE>   43
                                       37

         join with the purchasing Class D Certificateholder to purchase all,
         but not less than all, of the Certificates, the Class B Certificates
         and the Class C Certificates pro rata based on the Fractional
         Undivided Interest in the Class D Trust held by each such Class D

         any other Class D Certificateholder fails to notify the purchasing

         desire to participate in such a purchase, then such other Class D
         Certificateholder shall lose its right to purchase the Certificates
         pursuant to this Section 6.01(b).

                 The purchase price with respect to the Certificates shall be
equal to the Pool Balance of the Certificates, together with accrued and unpaid
interest thereon to the date of such purchase, without premium, but including
any other amounts then due and payable to the Certificateholders under this
Agreement, the Intercreditor Agreement, the Escrow Agreement or any Note
Document or on or in respect of the Certificates; provided, however, that (i)
if such purchase occurs after the record date specified in Section 2.03(b) of
the Escrow Agreement relating to the distribution of unused Deposits and
accrued and unpaid interest thereunder, such purchase price shall be reduced by
the aggregate amount of unused Deposits and interest to be distributed under
the Escrow Agreement (which deducted amounts shall remain distributable to, and
may be retained by, the Certificateholder as of such Record Date) and (ii) if
such purchase occurs after a Record Date, such purchase price shall be reduced
by the amount to be distributed hereunder on the related Distribution Date
(which deducted amounts shall remain distributable to, and may be retained by,
the Certificateholder as of such Record Date); provided further that no such
purchase of Certificates shall be effective unless the purchaser(s) shall
certify to the Trustee that contemporaneously with such purchase, such
purchaser(s) is purchasing, pursuant to the terms of this Agreement and the
Other Agreements, the Certificates, the Class B Certificates and the Class C
Certificates which are senior to the securities held by such purchaser(s).
Each payment of the purchase price of the Certificates referred to in the first
sentence hereof shall be made to an account or accounts designated by the
Trustee and each such purchase shall be subject to the terms of this Section
6.01(b).  Each Certificateholder agrees by its acceptance of its Certificate
that it will, subject to Section 3.04 of this Agreement, upon payment from such
Class B Certificateholder(s), Class C Certificateholder(s) or Class D
Certificateholder(s), as the case may be, of the purchase price set forth in
the first sentence of this paragraph, forthwith sell, assign, transfer and
convey to the purchaser(s) thereof (without recourse, representation or
warranty of any kind except for its own acts), all of the right, title,
interest and obligation of such Certificateholder in this Agreement, the Escrow
Agreement, the Deposit Agreement, the Intercreditor Agreement, the Liquidity
Facilities, the Note Documents and all Certificates and Escrow Receipts held by
such Certificateholder (excluding all right, title and interest under any of
the foregoing to the extent such right, title or interest is with respect to an
obligation not then due and payable as respects any action or inaction or state
of affairs occurring prior to such sale) and the purchaser shall assume all of
such Certificateholder's obligations under this Agreement, the Escrow
Agreement, the Deposit Agreement, the Intercreditor

                                       38

Agreement, the Liquidity Facilities, the Note Documents and all such
Certificates and Escrow Receipts.  The Certificates will be deemed to be
purchased on the date payment of the purchase price is made notwithstanding the
failure of the Certificateholders to deliver any Certificates and, upon such a
purchase, (i) the only rights of the Certificateholders will be to deliver the
Certificates to the purchaser(s) and receive the purchase price for such
Certificates and (ii) if the purchaser(s) shall so request, such
Certificateholder will comply with all the provisions of Section 3.04 of this
Agreement to enable new Certificates to be issued to the purchaser in such
denominations as it shall request.  All charges and expenses in connection with
the issuance of any such new Certificates shall be borne by the purchaser
thereof.

Certificateholder", "Class B Trust", "Class B Certificate", "Class B Trustee",
"Class C Certificate", "Class C Certificateholder", "Class C Trust", "Class C
Trustee", "Class D Certificateholder" and "Class D Trust", shall have the
respective meanings assigned to such terms in the Intercreditor Agreement.

                 Section 6.02.  Incidents of Sale of Equipment Notes.  Upon any
sale of all or any part of the Equipment Notes held in the Trust made either
under the power of sale given under this Agreement or otherwise for the
enforcement of this Agreement, the following shall be applicable:

                 (a)      Certificateholders and Trustee May Purchase Equipment
         Notes.  Any Certificateholder, the Trustee in its individual or any
         other capacity or any other Person may bid for and purchase any of the
         Equipment Notes held in the Trust, and upon compliance with the terms
         of sale, may hold, retain, possess and dispose of such Equipment Notes
         in their own absolute right without further accountability.

                 (b)      Receipt of Trustee Shall Discharge Purchaser.  The
         receipt of the Trustee making such sale shall be a sufficient
         discharge to any purchaser for his purchase money, and, after paying
         such purchase money and receiving such receipt, such purchaser or its
         personal representative or assigns shall not be obliged to see to the
         application of such purchase money, or be in any way answerable for
         any loss, misapplication or nonapplication thereof.

                 (c)      Application of Moneys Received upon Sale.  Any moneys
         collected by the Trustee upon any sale made either under the power of
         sale given by this Agreement or otherwise for the enforcement of this
         Agreement shall be applied as provided in Section 4.02.

                 Section 6.03.  Judicial Proceedings Instituted by Trustee;
Trustee May Bring Suit.  If there shall be a failure to make payment of the
principal of, premium, if any, or
<PAGE>   45
                                       39

interest on any Equipment Note held in the Trust, or if there shall be any
failure to pay Rent (as defined in the relevant Lease) under any Lease when due
and payable, then the Trustee, in, its own name and as trustee of an express
trust, as holder of such Equipment Notes, to the extent permitted by and in
accordance with the terms of any related Intercreditor Agreement and any
related Note Documents (subject to rights of the applicable Owner Trustee or
Owner Participant to cure any such failure to pay principal of, premium, if
any, or interest on any Equipment Note or to pay Rent under any Lease in
accordance with the applicable Indenture), shall be entitled and empowered to
institute any suits, actions or proceedings at law, in equity or otherwise, for
the collection of the sums so due and unpaid on such Equipment Notes or under
such Lease and may prosecute any such claim or proceeding to judgment or final
decree with respect to the whole amount of any such sums so due and unpaid.

                 Section 6.04.  Control by Certificateholders.  Subject to
Section 6.03 and the Intercreditor Agreement, the Certificateholders holding
Certificates evidencing Fractional Undivided Interests aggregating not less
than a majority in interest in the related Trust shall have the right to direct
the time, method and place of conducting any proceeding for any remedy
available to the Trustee with respect to the Trust or pursuant to the terms of
the Intercreditor Agreement, or exercising any trust or power conferred on the
Trustee under this Agreement or the Intercreditor Agreement, including any
right of the Trustee as Controlling Party under the Intercreditor Agreement or
as holder of the Equipment Notes held in the related Trust; provided, however,
that

                 (a)      such Direction shall not in the opinion of the
         Trustee be in conflict with any rule of law or with this Agreement and
         would not involve the Trustee in personal liability or expense,

                 (b)      the Trustee shall not determine that the action so
         directed would be unjustly prejudicial to the Certificateholders not
         taking part in such Direction, and

                 (c)      the Trustee may take any other action deemed proper
         by the Trustee which is not inconsistent with such Direction.

                 Section 6.05.  Waiver of Past Defaults.  Subject to any
related Intercreditor Agreement, the Certificateholders holding Certificates of
a series evidencing Fractional Undivided Interests aggregating not less than a
majority in interest in the Trust (i) may on behalf of all of the
Certificateholders waive any past Event of Default hereunder and its
consequences or (ii) if the Trustee is the Controlling Party, may direct the
Trustee to instruct the applicable Loan Trustee to waive any past Indenture
Event of Default under any related Indenture and its consequences, and thereby
annul any Direction given by such Certificateholders or the Trustee to such
Loan Trustee with respect thereto, except a default:
<PAGE>   46
                                       40

                 (a)      in the deposit of any Scheduled Payment or Special
         Payment under Section 4.01 or in the distribution of any payment under
         Section 4.02 on the Certificates, or

                 (b)      in the payment of the principal of (premium, if any)
         or interest on the Equipment Notes held in the Trust, or

                 (c)      in respect of a covenant or provision hereof which
         under Article IX hereof cannot be modified or amended without the
         consent of each Certificateholder holding an Outstanding Certificate
         of a series affected thereby.

Upon any such waiver, such default shall cease to exist with respect to the
Certificates and any Event of Default arising therefrom shall be deemed to have
been cured for every purpose and any direction given by the Trustee on behalf
of the Certificateholders to the relevant Loan Trustee shall be annulled with
respect thereto; but no such waiver shall extend to any subsequent or other
default or Event of Default or impair any right consequent thereon.  Upon any
such waiver, the Trustee shall vote the Equipment Notes issued under the
relevant Indenture to waive the corresponding Indenture Event of Default.

                 Section 6.06.  Right of Certificateholders to Receive Payments
Not to Be Impaired.  Anything in this Agreement to the contrary
notwithstanding, including, without limitation, Section 6.07 hereof, but
subject to the Intercreditor Agreement, the right of any Certificateholder to
receive distributions of payments required pursuant to Section 4.02 hereof on
the applicable Certificates when due, or to institute suit for the enforcement
of any such payment on or after the applicable Regular Distribution Date or
Special Distribution Date, shall not be impaired or affected without the
consent of such Certificateholder.

                 Section 6.07.  Certificateholders May Not Bring Suit Except
Under Certain Conditions.  A Certificateholder shall not have the right to
institute any suit, action or proceeding at law or in equity or otherwise with
respect to this Agreement, for the appointment of a receiver or for the
enforcement of any other remedy under this Agreement, unless:

                 (a)      such Certificateholder previously shall have given
         written notice to the Trustee of a continuing Event of Default;

                 (b)      Certificateholders holding Certificates evidencing
         Fractional Undivided Interests aggregating not less than 25% of the
         related Trust shall have requested the Trustee in writing to institute
         such action, suit or proceeding and shall have offered to the Trustee
         indemnity as provided in Section 7.03(e);
<PAGE>   47
                                       41

                 (c)      the Trustee shall have refused or neglected to
         institute any such action, suit or proceeding for 60 days after
         receipt of such notice, request and offer of indemnity; and

                 (d)      no direction inconsistent with such written request
         shall have been given to the Trustee during such 60-day period by
         Certificateholders holding Certificates evidencing Fractional
         Undivided Interests aggregating not less than a majority in interest
         in the Trust.

                 It is understood and intended that no one or more of the
Certificateholders shall have any right in any manner whatsoever hereunder or
under the related Trust Supplement or under the Certificates to (i) surrender,
impair, waive, affect, disturb or prejudice any property in the Trust Property
of the Trust, or the lien of any related Indenture on any property subject
thereto, or the rights of the Certificateholders or the holders of the
Equipment Notes, (ii) obtain or seek to obtain priority over or preference with
respect to any other such Certificateholder or (iii) enforce any right under
this Agreement, except in the manner herein provided and for the equal, ratable
and common benefit of all the Certificateholders subject to the provisions of
this Agreement.

                 Section 6.08.  Remedies Cumulative.  Every remedy given
hereunder to the Trustee or to any of the Certificateholders shall not be
exclusive of any other remedy or remedies, and every such remedy shall be
cumulative and in addition to every other remedy given hereunder or now or
hereafter given by statute, law, equity or otherwise.

                 Section 6.09.  Undertaking for Costs.  In any suit for the
enforcement of any right or remedy under this Agreement, or in any suit against
the Trustee for any action taken, suffered or omitted by it as Trustee, a court
may require any party litigant in such suit to file an undertaking to pay the
costs of such suit, and may assess costs against any such party litigant, in
the manner and to the extent provided in the Trust Indenture Act; provided,
however, that neither this Section 6.09 nor the Trust Indenture Act shall be
deemed to authorize any court to require such an undertaking or to make such an
assessment in any suit instituted by the Company.

                                  THE TRUSTEE

                 Section 7.01.  Certain Duties and Responsibilities.  (a)
Except during the continuance of an Event of Default in respect of a Trust, the
Trustee undertakes to perform such duties in respect of the Trust as are
specifically set forth in this Agreement, and no implied covenants or
obligations shall be read into this Agreement against the Trustee.
<PAGE>   48
                                       42


                 (b)      In case an Event of Default in respect of a Trust has
occurred and is continuing, the Trustee shall exercise such of the rights and
powers vested in it by this Agreement in respect of the Trust, and use the same
degree of care and skill in their exercise, as a prudent man would exercise or
use under the circumstances in the conduct of his own affairs.

                 (c)      No provision of this Agreement 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

                 (i)      this Subsection shall not be construed to limit the
         effect of Subsection (a) of this Section 7.01; and

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

                 (d)      Whether or not herein expressly so provided, every
provision of this Agreement relating to the conduct or affecting the liability
of or affording protection to the Trustee shall be subject to the provisions of
this Section 7.01.

                 Section 7.02.  Notice of Defaults.  As promptly as practicable
after, and in any event within 90 days after, the occurrence of any default (as
such term is defined below) hereunder known to the Trustee, the Trustee shall
transmit by mail to the Company, any Owner Trustees, the Owner Participants,
the Loan Trustees and the Certificateholders holding Certificates in accordance
with Section 313(c) of the Trust Indenture Act, notice of such default
hereunder known to the Trustee, unless such default shall have been cured or
waived; provided, however, that, except in the case of a default in the payment
of the principal, premium, if any, or interest on any Equipment 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 shall determine that
the withholding of such notice is in the interests of the Certificateholders.
For the purpose of this Section 7.02 in respect of any Trust, the term
"default" means any event that is, or after notice or lapse of time or both
would become, an Event of Default in respect of that Trust.

                 Section 7.03.  Certain Rights of Trustee.  Subject to the
provisions of Section 315 of the Trust Indenture Act:

                 (a)      the Trustee may rely and shall be protected in acting
         or refraining from acting in reliance upon any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture or other paper or

                                       43

         document believed by it to be genuine and to have been signed or
         presented by the proper party or parties;

                 (b)      any request or direction of the Company mentioned
         herein shall be sufficiently evidenced by a Request;

                 (c)      whenever in the administration of this Agreement or
         the Intercreditor Agreement, 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 Officer's Certificate of the Company, any Owner
         Trustee or any Loan Trustee;

                 (d)      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;

                 (e)      the Trustee shall be under no obligation to exercise
         any of the rights or powers vested in it by this Agreement or the
         Intercreditor Agreement at the Direction of any of the
         Certificateholders pursuant to this Agreement or the Intercreditor
         Agreement, unless the Certificateholders shall have offered to the
         Trustee reasonable security or indemnity against the cost, expenses
         and liabilities which might be incurred by it in compliance with such
         Direction;

                 (f)      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 or other paper or document;

                 (g)      the Trustee may execute any of the trusts or powers
         under this Agreement or the Intercreditor Agreement or perform any
         duties under this Agreement or the Intercreditor Agreement 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 under this Agreement
         or the Intercreditor Agreement;

                 (h)      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 Certificateholders holding Certificates
         evidencing Fractional Undivided Interests aggregating not less than a
         majority in interest in the Trust relating to the time, method and
         place of conducting any proceeding for any remedy available to the
<PAGE>   50
                                       44

         Trustee, or exercising any trust or power conferred upon the Trustee,
         under this Agreement or the Intercreditor Agreement; and

                 (i)      the Trustee shall not be required to expend or risk
         its own funds in the performance of any of its duties under this
         Agreement, 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 is not reasonably
         assured to it.

                 Section 7.04.  Not Responsible for Recitals or Issuance of
Certificates.  The recitals contained herein and in the Certificates, except
the certificates of authentication, shall not be taken as the statements of the
Trustee, and the Trustee assumes no responsibility for their correctness.
Subject to Section 7.15, the Trustee makes no representations as to the
validity or sufficiency of this Agreement, any Equipment Notes, the
Intercreditor Agreement, the Deposit Agreement, the Escrow Agreement, the
Certificates, or any Note Documents, except that the Trustee hereby represents
and warrants that this Agreement has been, and the Registration Rights
Agreement, each Certificate, the Note Purchase Agreement, the Escrow Agreement
and the Intercreditor Agreement will be, executed and delivered by one of its
officers who is duly authorized to execute and deliver such document on its
behalf.

                 Section 7.05.  May Hold Certificates.  The Trustee, any Paying
Agent, Registrar or any of their Affiliates or any other agent, in their
respective individual or any other capacity, may become the owner or pledgee of
Certificates and, subject to Sections 310(b) and 311 of the Trust Indenture
Act, if applicable, may otherwise deal with the Company, any Owner Trustees or
the Loan Trustees with the same rights it would have if it were not Trustee,
Paying Agent, Registrar or such other agent.

                 Section 7.06.  Money Held in Trust.  Money held by the Trustee
or the Paying Agent in trust under this Agreement need not be segregated from
other funds except to the extent required herein or by law and neither the
Trustee nor the Paying Agent shall have any liability for interest upon any
such moneys except as provided for herein.

                 Section 7.07.  Compensation and Reimbursement.  The Company
agrees:

                 (a)      to pay, or cause to be paid, to the Trustee from time
         to time  reasonable compensation for all services rendered by it
         hereunder (which compensation shall not be limited by any provision of
         law in regard to the compensation of a trustee of an express trust);
         and

                 (b)      to reimburse, or cause to be reimbursed, the Trustee
         upon its request for all reasonable out- of-pocket expenses,
         disbursements and advances incurred or made by the Trustee in
         accordance with any provision of this Agreement or the Intercreditor
         Agreement (including the reasonable compensation and the expenses and
<PAGE>   51
                                       45

         disbursements of its agents and counsel), except any such expense,
         disbursement or advance as may be attributable to its negligence,
         willful misconduct or bad faith or as may be incurred due to the
         Trustee's breach of its representations and warranties set forth in
         Section 7.15; and

                 (c)      to indemnify the Trustee with respect to the
         Certificates, pursuant to Section 8.1 of the Owned Aircraft
         Participation Agreements and Section 9.1 of the Leased Aircraft
         Participation Agreements, as the case may be.

                 The Trustee shall be entitled to reimbursement from, and shall
have a lien prior to the Certificates upon, all property and funds held or
collected by the Trustee in its capacity as Trustee for any tax incurred
without negligence, bad faith or willful misconduct, on its part, arising out
of or in connection with the acceptance or administration of the Trust (other
than any tax attributable to the Trustee's compensation for serving as such),
including any costs and expenses incurred in contesting the imposition of any
such tax.  The Trustee shall notify the Company of any claim for any tax for
which it may seek reimbursement.  If the Trustee reimburses itself from the
Trust Property of such Trust for any such tax, it will mail a brief report
within 30 days setting forth the amount of such tax and the circumstances
thereof to all Certificateholders as their names and addresses appear in the
Register.

                 Section 7.08.  Corporate Trustee Required; Eligibility.  The
Trust shall at all times have a Trustee which shall be eligible to act as a
trustee under Section 310(a) of the Trust Indenture Act and shall have a
combined capital and surplus of at least $75,000,000 (or a combined capital and
surplus in excess of $5,000,000 and the obligations of which, whether now in
existence or hereafter incurred, are fully and unconditionally guaranteed by a
corporation organized and doing business under the laws of the United States,
any state or territory thereof or of the District of Columbia and having a
combined capital and surplus of at least $75,000,000).  If such corporation
publishes reports of conditions at least annually, pursuant to law or to the
requirements of federal, state, territorial or District of Columbia supervising
or examining authority, then for the purposes of this Section 7.08 the combined
capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of conditions so
published.

                 In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 7.08 to act as Trustee of the
Trust, the Trustee shall resign immediately as Trustee of the Trust in the
manner and with the effect specified in Section 7.09.

                 Section 7.09.  Resignation and Removal; Appointment of
Successor.  (a)  No resignation or removal of the Trustee and no appointment of
a successor Trustee of the Trust pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee under
Section 7.10.
<PAGE>   52
                                       46


                 (b)      The Trustee may resign at any time as Trustee of the
Trust by giving prior written notice thereof to the Company, the Authorized
Agents, the Owner Trustees and the Loan Trustees.  If an instrument of
acceptance by a successor Trustee shall not have been delivered to the Company,
the Owner Trustees and the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

                 (c)      The Trustee may be removed at any time by Direction
of the Certificateholders holding Certificates evidencing Fractional Undivided
Interests aggregating not less than a majority in interest in such Trust
delivered to the Trustee and to the Company, the Owner Trustees and the Loan
Trustees.

                 (d)      If at any time in respect of the Trust:

                 (i)      the Trustee shall fail to comply with Section 310 of
         the Trust Indenture Act, if applicable, after written request therefor
         by the Company or by any Certificateholder who has been a bona fide
         Certificateholder for at least six months; or

                 (ii)     the Trustee shall cease to be eligible under Section
         7.08 and shall fail to resign after written request therefor by the
         Company or by any such Certificateholder; or

                 (iii)    the Trustee shall become incapable of acting or shall
         be adjudged a bankrupt or insolvent, or a receiver of the Trustee or
         of its property shall be appointed or any public officer shall take
         charge or control of the Trustee or of its property or affairs for the
         purpose of rehabilitation, conservation or liquidation;

then, in any case, (i) the Company may remove the Trustee or (ii) any
Certificateholder who has been a bona fide Certificateholder for at least six
months may, on behalf of itself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee of the Trust.

                 (e)      If a Responsible Officer of the Trustee shall obtain
actual knowledge of an Avoidable Tax (as defined below) in respect of any Trust
which has been or is likely to be asserted, the Trustee shall promptly notify
the Company and shall, within 30 days of such notification, resign as Trustee
of such Trust hereunder unless within such 30-day period the Trustee shall have
received notice that the Company has agreed to pay such tax.  The Company shall
promptly appoint a successor Trustee of such Trust in a jurisdiction where
there are no Avoidable Taxes.  As used herein, an "Avoidable Tax" in respect of
such Trust means a state or local tax:  (i) upon (w) such Trust, (x) such Trust
Property, (y) Certificateholders of the Trust or (z) the Trustee for which the
Trustee is entitled to seek
<PAGE>   53
                                       47

reimbursement from the Trust Property of such Trust, and (ii) which would be
avoided if the Trustee were located in another state, or jurisdiction within a
state, within the United States of America.  A tax shall not be an Avoidable
Tax in respect of any Trust if the Company or any Owner Trustee shall agree to
pay, and shall pay, such tax.

                 (f)      If the Trustee shall resign, be removed or become
incapable of acting as Trustee of the Trust or if a vacancy shall occur in the
office of the Trustee of the Trust for any cause, the Company shall promptly
appoint a successor Trustee.  If, within one year after such resignation,
removal or incapability, or other occurrence of such vacancy, a successor
Trustee shall be appointed by Direction of the Certificateholders holding
Certificates evidencing Fractional Undivided Interests aggregating not less
than a majority in interest in such Trust delivered to the Company, the Owner
Trustees, the Loan Trustee and the retiring Trustee, then the successor Trustee
so appointed shall, with the approval of the Company of such appointment, which
approval shall not be unreasonably withheld, forthwith upon its acceptance of
such appointment, become the successor Trustee and supersede the successor
Trustee appointed as provided above.  If no successor Trustee shall have been
so appointed as provided above and accepted appointment in the manner
hereinafter provided, the resigning Trustee or any Certificateholder who has
been a bona fide Certificateholder of the related series for at least six
months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the appointment of a successor Trustee.

                 (g)      The successor Trustee shall give notice of the
resignation and removal of the Trustee and appointment of the successor Trustee
by mailing written notice of such event by first-class mail, postage prepaid,
to the Certificateholders as their names and addresses appear in the Register.
Each notice shall include the name of such successor Trustee and the address of
its Corporate Trust Office.

                 Section 7.10.  Acceptance of Appointment by Successor.  Every
successor Trustee appointed hereunder shall execute and deliver to the Company
and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on request of the Company or the successor
Trustee, such retiring Trustee shall execute and deliver an instrument
transferring to such successor Trustee all such rights, powers and trusts of
the retiring Trustee and shall duly assign, transfer and deliver to such
successor Trustee all Trust Property held by such retiring Trustee, subject
nevertheless to its lien, if any, provided for in Section 7.07.  Upon request
of any such successor Trustee, the Company, the retiring Trustee and such
successor Trustee shall execute and deliver any and all instruments containing
such provisions as shall be necessary or desirable to transfer and confirm to,
and for more fully and certainly vesting in, such successor Trustee all such
rights, powers and trusts.
<PAGE>   54
                                       48


                 No institution shall accept its appointment as a Trustee
hereunder unless at the time of such acceptance such institution shall be
qualified and eligible under this Article VII.

                 Section 7.11.  Merger, Conversion, Consolidation or Succession
to Business.  Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder;
provided, however, that such corporation shall be otherwise qualified and
eligible under this Article VII, without the execution or filing of any paper
or any further act on the part of any of the parties hereto.  In case any
Certificates shall have been executed or authenticated, but not delivered, by
the Trustee then in office, any successor by merger, conversion or
consolidation to such authenticating Trustee may adopt such execution or
authentication and deliver the Certificates so executed or authenticated with
the same effect as if such successor Trustee had itself executed or
authenticated such Certificates.

                 Section 7.12.  Maintenance of Agencies.  (a)  With respect to
each series of Certificates, there shall at all times be maintained an office
or agency in the location set forth in Section 12.04 where Certificates may be
presented or surrendered for registration of transfer or for exchange, and for
payment thereof, and where notices and demands, to or upon the Trustee in
respect of such Certificates or this Agreement may be served; provided,
however, that, if it shall be necessary that the Trustee maintain an office or
agency in another location with respect to the Certificates (e.g., the
Certificates shall be represented by Definitive Certificates and shall be
listed on a national securities exchange), the Trustee will make all reasonable
efforts to establish such an office or agency.  Written notice of the location
of each such other office or agency and of any change of location thereof shall
be given by the Trustee to the Company, any Owner Trustees, the Loan Trustees
(in the case of any Owner Trustee or Loan Trustee, at its address specified in
the Note Documents or such other address as may be notified to the Trustee) and
the Certificateholders.  In the event that no such office or agency shall be
maintained or no such notice of location or of change of location shall be
given, presentations and demands may be made and notices may be served at the
Corporate Trust Office of the Trustee.

                 (b)      There shall at all times be a Registrar and a Paying
Agent hereunder with respect to the Certificates.  Each such Authorized Agent
shall be a bank or trust company, shall be a corporation organized and doing
business under the laws of the United States or any state, with a combined
capital and surplus of at least $75,000,000, or a corporation having a combined
capital and surplus in excess of $5,000,000, the obligations of which are
guaranteed by a corporation organized and doing business under the laws of the
United States or any state, with a combined capital and surplus of at least
$75,000,000, and shall be authorized under such laws to exercise corporate
trust powers, subject to supervision by federal or state authorities.  The
Trustee shall initially be the Paying Agent and, as
<PAGE>   55
                                       49

provided in Section 3.04, Registrar hereunder with respect to the Certificates.
Each Registrar shall furnish to the Trustee, at stated intervals of not more
than six months, and at such other times as the Trustee may request in writing,
a copy of the Register maintained by such Registrar.

                 (c)      Any corporation into which any Authorized Agent may
be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, consolidation or conversion to which any Authorized
Agent shall be a party, or any corporation succeeding to the corporate trust
business of any Authorized Agent, shall be the successor of such Authorized
Agent, if such successor corporation is otherwise eligible under this Section
7.12, without the execution or filing of any paper or any further act on the
part of the parties hereto or such Authorized Agent or such successor
corporation.

                 (d)      Any Authorized Agent may at any time resign by giving
written notice of resignation to the Trustee, the Company, any Owner Trustees
and the Loan Trustees.  The Company may, and at the request of the Trustee
shall, at any time terminate the agency of any Authorized Agent by giving
written notice of termination to such Authorized Agent and to the Trustee.
Upon the resignation or termination of an Authorized Agent or in case at any
time any such Authorized Agent shall cease to be eligible under this Section
7.12 (when, in either case, no other Authorized Agent performing the functions
of such Authorized Agent shall have been appointed), the Company shall promptly
appoint one or more qualified successor Authorized Agents, reasonably
satisfactory to the Trustee, to perform the functions of the Authorized Agent
which has resigned or whose agency has been terminated or who shall have ceased
to be eligible under this Section 7.12.  The Company shall give written notice
of any such appointment made by it to the Trustee, any Owner Trustees and the
Loan Trustees; and in each case the Trustee shall mail notice of such
appointment to all Certificateholders as their names and addresses appear on
the Register for such series.

                 (e)      The Company agrees to pay, or cause to be paid, from
time to time to each Authorized Agent reasonable compensation for its services
and to reimburse it for its reasonable expenses.

                 Section 7.13.  Money for Certificate Payments to Be Held in
Trust.  All moneys deposited with any Paying Agent for the purpose of any
payment on Certificates shall be deposited and held in trust for the benefit of
the Certificateholders entitled to such payment, subject to the provisions of
this Section 7.13. Moneys so deposited and held in trust shall constitute a
separate trust fund for the benefit of the Certificateholders with respect to
which such money was deposited.

                 The Trustee may at any time, for the purpose of obtaining the
satisfaction and discharge of this Agreement or for any other purpose, direct
any Paying Agent to pay to the Trustee all sums held in trust by such Paying
Agent, such sums to be held by the Trustee
<PAGE>   56
                                       50

upon the same trusts as those upon which such sums were held by such Paying
Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying
Agent shall be released from all further liability with respect to such money.

                 Section 7.14.  Registration of Equipment Notes in Trustee's
Name.  Subject to the provisions of any Intercreditor Agreement, the Trustee
agrees that all Equipment Notes to be purchased by any Trust and Permitted
Investments, if any, shall be issued in the name of the Trustee as trustee for
the applicable Trust or its nominee and held by the Trustee in trust for the
benefit of the Certificateholders, or, if not so held, the Trustee or its
nominee shall be reflected as the owner of such Equipment Notes or Permitted
Investments, as the case may be, in the register of the issuer of such
Equipment Notes or Permitted Investments, as the case may be.

                 Section 7.15.  Representations and Warranties of Trustee.  The
Trustee hereby represents and warrants, on the Transfer Date, that:

                 (a)      the Trustee is a Delaware banking corporation

         mortgage, indenture, contract, agreement or other undertaking to which

         transactions contemplated herein or therein;
<PAGE>   57
                                       51

         giving of notice to, the filing or registration with, or the taking of
         any other action in respect of, any governmental authority or agency
         of the United States or the state of the United States where it is

         the Trustee and constitute, or will constitute, as applicable, the
         legal, valid and binding agreements of the Trustee, enforceable

         principles of equity.

                 Section 7.16.  Withholding Taxes; Information Reporting.  As
to the Certificates, the Trustee, as trustee of the related grantor trust
created by this Agreement, shall exclude and withhold from each distribution of
principal, premium, if any, and interest and other amounts due under this
Agreement or under the Certificates any and all withholding taxes applicable
thereto as required by law.  The Trustee agrees to act as such withholding
agent and, in connection therewith, whenever any present or future taxes or
similar charges are required to be withheld with respect to any amounts payable
in respect of the Certificates, to withhold such amounts and timely pay the
same to the appropriate authority in the name of and on behalf of the
Certificateholders, that it will file any necessary withholding tax returns or
statements when due, and that, as promptly as possible after the payment
thereof, it will deliver to each such Certificateholder appropriate
documentation showing the payment thereof, together with such additional
documentary evidence as such Certificateholders may reasonably request from
time to time.  The Trustee agrees to file any other information reports as it

Agreement, at its own cost and expense promptly take any action as may be

respect to the Trust Property of such Trust which is attributable to the
Trustee either (i) in its individual capacity and which is unrelated to the
transactions contemplated by this Agreement, the Intercreditor Agreement, the
Note Purchase Agreement or the Note

         applicable law, rules or regulations of any exchange or quotation
         system on which the Certificates are listed or of any regulatory body;

<PAGE>   62
                                       56

supplemental hereto for the purpose of adding any provisions to or changing in

Certificateholders or of modifying in any manner the rights and obligations of

                 (b)      permit the disposition of any Equipment Note included
         in the Trust Property of such Trust except as permitted by this

                 (c)      alter the priority of distributions specified in the
         Intercreditor Agreement in a manner materially adverse to the
         interests of the Certificateholders; or

         Agreement or certain defaults hereunder and their consequences)
         provided for in this Agreement; or

                 (e)      modify any of the provisions of this Section 9.02 or
         Section 6.05, except to increase any such percentage or to provide
         that certain other provisions of this Agreement cannot be modified or
         waived without the consent of the Certificateholder of each

         trust under Subpart E, Part I of Subchapter J of Chapter 1 of Subtitle

                                       57

                 It shall not be necessary for any Direction of such
Certificateholders under this Section 9.02 to approve the particular form of
any proposed supplemental agreement, but it shall be sufficient if such
Direction shall approve the substance thereof.

                 Section 9.03.  Documents Affecting Immunity or Indemnity.  If
in the opinion of the Trustee any document required to be executed by it
pursuant to the terms of Section 9.01 or 9.02 affects any interest, right,
duty, immunity or indemnity in favor of the Trustee under this Agreement or any
Trust Supplement, the Trustee may in its discretion decline to execute such
document.

                 Section 9.04.  Execution of Supplemental Agreements.  In
executing, or accepting the additional trusts created by, any supplemental
agreement permitted by this Article or the modifications thereby of the trusts
created by this Agreement, the Trustee shall be entitled to receive, and shall
be fully protected in relying upon, an Opinion of Counsel stating that the
execution of such supplemental agreement is authorized or permitted by this
Agreement.

                 Section 9.05.  Effect of Supplemental Agreements.  Upon the
execution of any agreement supplemental to this Agreement under this Article,
this Agreement shall be modified in accordance therewith, and such supplemental
agreement shall form a part of this Agreement for all purposes; and every
Certificateholder theretofore or thereafter authenticated and delivered
hereunder shall be bound thereby to the extent applicable to such series.

                 Section 9.06.  Conformity with Trust Indenture Act.  Every
supplemental agreement executed pursuant to this Article shall conform to the
requirements of the Trust Indenture Act as then in effect.

                 Section 9.07.  Reference in Certificates to Supplemental
Agreements.  Certificates authenticated and delivered after the execution of
any supplemental agreement  pursuant to this Article may bear a notation in
form approved by the Trustee as to any matter provided for in such supplemental
agreement; and, in such case, suitable notation may be made upon Outstanding
Certificates after proper presentation and demand.

                   AMENDMENTS TO INDENTURE AND NOTE DOCUMENTS

                 Section 10.01.  Amendments and Supplements to Indenture and
Other Note Documents.  In the event that the Trustee, as holder (or beneficial
owner through the Subordination Agent) of any Equipment Notes (or as a
prospective purchaser of any
<PAGE>   64
                                       58

Postponed Notes) in trust for the benefit of the Certificateholders or as
Controlling Party under an Intercreditor Agreement, receives (directly or
indirectly through the Subordination Agent) a request for a consent to any
amendment, modification, waiver or supplement under any Indenture, other Note
Document or any other related document, which request would require the consent
of Certificateholders under Section 9.02 hereof, the Trustee shall forthwith
send a notice of such proposed amendment, modification, waiver or supplement to
each Certificateholder registered on the Register as of the date of such
notice.  The Trustee shall request from the Certificateholders a Direction as
to (a) whether or not to take or refrain from taking (or direct the
Subordination Agent to take or refrain from taking) any action which a holder
of (or, with respect to Postponed Notes, a prospective purchaser of) such
Equipment Note or a Controlling Party has the option to direct, (b) whether or
not to give or execute (or direct the Subordination Agent to give or execute)
any waivers, consents, amendments, modifications or supplements as a holder of
(or, with respect to Postponed Notes, a prospective purchaser of) such
Equipment Note or as Controlling Party and (c) how to vote (or direct the
Subordination Agent to vote) any Equipment Note (or, with respect to a
Postponed Note, its commitment to acquire such Postponed Note) if a vote has
been called for with respect thereto.  Provided such a request for
Certificateholder Direction shall have been made, in directing any action or
casting any vote or giving any consent as the holder of any Equipment Note (or
in directing the Subordination Agent in any of the foregoing), (i) other than
as Controlling Party, the Trustee shall vote for or give consent to any such
action with respect to such Equipment Note (or Postponed Note) in the same
proportion as that of (A) the aggregate face amounts of all Certificates
actually voted in favor of or for giving consent to such action by such
Direction of Certificateholders to (B) the aggregate face amount of all
Outstanding Certificates and (ii) as Controlling Party, the Trustee shall vote
as directed in such Certificateholder Direction by the Certificateholders
evidencing a Fractional Undivided Interest aggregating not less than a majority
in interest in the Trust.  For purposes of the immediately preceding sentence,
a Certificate shall have been "actually voted" if the Holder of such
Certificate has delivered to the Trustee an instrument evidencing such Holder's
consent to such Direction prior to one Business Day before the Trustee directs
such action or casts such vote or gives such consent.  Notwithstanding the
foregoing, but subject to Section 6.04 and any Intercreditor Agreement, the
Trustee may, with respect to the Certificates, in its own discretion and at its
own direction, consent and notify the relevant Loan Trustee of such consent (or
direct the Subordination Agent to consent and notify the Loan Trustee of such
consent) to any amendment, modification, waiver or supplement under any related
Indenture or any other related Note Document if an Event of Default hereunder
shall have occurred and be continuing or if such amendment, modification,
waiver or supplement will not materially adversely affect the interests of the
Certificateholders.

                                   ARTICLE XI

                             TERMINATION OF TRUSTS

                 Section 11.01.  Termination of the Trust.  The respective
obligations and responsibilities of the Company and the Trustee shall terminate
upon the distribution to all Certificateholders and the Trustee of all amounts
required to be distributed to them pursuant to this Agreement and the
disposition of all property held as part of the Trust Property; provided,
however, that in no event shall the Trust continue beyond one hundred ten (110)
years following the date of the execution of this Agreement.

                 Notice of any termination, specifying the Distribution Date
upon which the Certificateholders may surrender their Certificates to the
Trustee for payment of the final distribution and cancellation, shall be mailed
promptly by the Trustee to Certificateholders not earlier than the 60th day and
not later than the 15th day next preceding such final Distribution Date
specifying (A) the Distribution Date upon which the proposed final payment of
the Certificates will be made upon presentation and surrender of Certificates
at the office or agency of the Trustee therein specified, (B) the amount of any
such proposed final payment, and (c) that the Record Date otherwise applicable
to such Distribution Date is not applicable, payments being made only upon
presentation and surrender of the Certificates at the office or agency of the
Trustee therein specified.  The Trustee shall give such notice to the Registrar
at the time such notice is given to Certificateholders.  Upon presentation and
surrender of the Certificates in accordance with such notice, the Trustee shall
cause to be distributed to Certificateholders such final payments.

                 In the event that all of the Certificateholders shall not
surrender their Certificates for cancellation within six months after the date
specified in the above-mentioned written notice, the Trustee shall give a
second written notice to the remaining Certificateholders to surrender their
Certificates for cancellation and receive the final distribution with respect
thereto.  No additional interest shall accrue on the Certificates after the
Distribution Date specified in the first written notice.  In the event that any
money held by the Trustee for the payment of distributions on the Certificates
shall remain unclaimed for two years (or such lesser time as the Trustee shall
be satisfied, after sixty days' notice from the Company, is one month prior to
the escheat period provided under applicable law) after the final distribution
date with respect thereto, the Trustee shall pay to each Loan Trustee the
appropriate amount of money relating to such Loan Trustee and shall give
written notice thereof to the related Owner Trustees, the Owner Participants
and the Company.

                            MISCELLANEOUS PROVISIONS

                 Section 12.01.  Limitation on Rights of Certificateholders.
The death or incapacity of any Certificateholder shall not operate to terminate
this Agreement or the Trust, nor entitle such Certificateholder's legal
representatives or heirs to claim an accounting or to take any action or
commence any proceeding in any court for a partition or winding up of the
Trust, nor otherwise affect the rights, obligations, and liabilities of the
parties hereto or any of them.

                 Section 12.02.  Liabilities of Certificateholders.  Neither
the existence of the Trust nor any provision in this Agreement is intended to
or shall limit the liability the Certificateholders would otherwise incur if
the Certificateholders owned Trust Property as co-owners, or incurred any
obligations of the Trust, directly rather than through the Trust.

                 Section 12.03.  Registration of Equipment Notes in Name of
Subordination Agent.  If the Trust is party to the Intercreditor Agreement, the
Trustee agrees that all Equipment Notes to be purchased by such Trust shall be
issued in the name of the Subordination Agent under the Intercreditor Agreement
or its nominee and held by such Subordination Agent in trust for the benefit of
the Certificateholders, or, if not so held, such Subordination Agent or its
nominee shall be reflected as the owner of such Equipment Notes in the register
of the issuer of such Equipment Notes.

                 Section 12.04.  Notices.  (a)  Unless otherwise specifically
provided herein, all notices required under the terms and provisions of this
Agreement shall be in English and in writing, and any such notice may be given
by United States mail, courier service or telecopy, and any such notice shall
be effective when delivered or received or, if mailed, three days after deposit
in the United States mail with proper postage for ordinary mail prepaid,

                 Section 12.14.  Intention of Parties.  The parties hereto
intend that each Trust be classified for U.S.  federal income tax purposes as a
grantor trust under Subpart E, Part I of Subchapter J of the Internal Revenue
Code of 1986, as amended, and not as a trust or association taxable as a
corporation or as a partnership.  The Trustee agrees to hold all assets of each
Trust for investment purposes only.  Each Certificateholder and Investor, by
its acceptance of its Certificate or a beneficial interest therein, agrees to
treat the Trust as a grantor trust for all U.S. federal, state and local income
tax purposes.  The powers granted and obligations undertaken pursuant to this
Agreement shall be so construed so as to further such intent.

                 IN WITNESS WHEREOF, the parties have caused this Agreement to
be duly executed by their respective officers hereunto duly authorized as of
the day and year first written above.

         individual, 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

                 (d)      a statement as to whether, in the opinion of each
         such individual, such condition or covenant has been complied with.

                 Section 1.03.  Form of Documents Delivered to Trustee.  In any
case where several matters are required to be certified by, or covered by an
opinion of, any specified Person, it is not necessary that all such matters be
certified by, or covered by the opinion of, only one such Person, or that they
be so certified or covered by only one document, but one such Person may
certify or give an opinion with respect to some matters and one or more other
such Persons as to other matters and any such Person may certify or give an
opinion as to such matters in one or several documents.

                 Where any Person is required to make, give or execute two or
more applications, requests, consents, certificates, statements, opinions or
other instruments under this Agreement, they may, but need not, be consolidated
and form one instrument.

                 Section 1.04.  Directions of Certificateholders.  (a)  Any
direction, consent, request, demand, authorization, notice, waiver or other
action provided by this Agreement in respect of the Certificates to be given or
taken by Certificateholders (a "Direction") may be embodied in and evidenced by
one or more instruments of substantially similar tenor signed by such
Certificateholders in person or by an agent or proxy 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,
when it is hereby expressly required pursuant to this Agreement, to the Company
or any Loan Trustee.  Such instrument or instruments (and the action embodied
therein and evidenced thereby) are herein sometimes referred to as the "Act" of
the Certificateholders signing such instrument or instruments.  Proof of
execution of any such instrument or of a writing appointing any such agent or
proxy shall be sufficient for any purpose of this Trust Agreement and
conclusive in favor of the Trustee, the Company and the related Loan Trustee,
if made in the manner provided in this Section 1.04.

                 (b)      The fact and date of the execution by any Person of
any such instrument or writing may be proved by the certificate of any notary
public or other officer of any jurisdiction authorized to take acknowledgments
of deeds or administer oaths that the Person executing such instrument
acknowledged to him the execution thereof, or by an affidavit of a witness to
such execution sworn to before any such notary or such other officer, and where
such execution is by an officer of a corporation or association or a member of
a partnership, on behalf of such corporation, association or partnership, such
<PAGE>   23
                                       17

certificate or affidavit shall also constitute sufficient proof of his
authority.  The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other reasonable manner which the Trustee deems sufficient.

                 (c)      In determining whether the Certificateholders of the
requisite Fractional Undivided Interests of Certificates Outstanding have given
any Direction under this Agreement, Certificates owned by the Company or any
Affiliate thereof shall be disregarded and deemed not to be Outstanding for
purposes of any such determination.  In determining whether the Trustee shall
be protected in relying upon any such Direction, only Certificates which the
Trustee knows to be so owned shall be so disregarded.  Notwithstanding the
foregoing, (i) if any such Person owns 100% of the Certificates Outstanding,
such Certificates shall not be so disregarded, and (ii) if any amount of
Certificates so owned by any such Person have been pledged in good faith, such
Certificates shall not be disregarded if the pledgee establishes to the
satisfaction of the Trustee the pledgee's right so to act with respect to such
Certificates and that the pledgee is not the Company or any Affiliate thereof.

                 (d)      The Company may, at its option, by delivery of an
Officer's Certificate to the Trustee, set a record date to determine the
Certificateholders in respect of the Certificates, entitled to give any
Direction.  Notwithstanding Section 316(c) of the Trust Indenture Act, such
record date shall be the record date specified in such Officer's Certificate,
which shall be a date not more than 30 days prior to the first solicitation of
Certificateholders of the applicable series in connection therewith.  If such a
record date is fixed, such Direction may be given before or after such record
date, but only the Certificateholders of record of the applicable series at the
close of business on such record date shall be deemed to be Certificateholders
for the purposes of determining whether Certificateholders of the requisite
proportion of Outstanding Certificates have authorized or agreed or consented
to such Direction, and for that purpose the Outstanding Certificates shall be
computed as of such record date; provided, however, that no such Direction by
the Certificateholders on such record date shall be deemed effective unless it
shall become effective pursuant to the provisions of this Agreement not later
than one year after such record date.

                 (e)      Any Direction by the Holder of any Certificate shall
bind the Holder of every Certificate issued upon the transfer thereof or in
exchange therefor or in lieu thereof, whether or not notation of such Direction
is made upon such Certificate.

                 (f)      Except as otherwise provided in Section 1.04(c),
Certificates owned by or pledged to any Person shall have an equal and
proportionate benefit under the provisions of this Agreement, without
preference, priority or distinction as among all of the Certificates.

                                   ARTICLE II

                       ORIGINAL ISSUANCE OF CERTIFICATES:
                         ACQUISITION OF TRUST PROPERTY

                 Section 2.01.  Delivery of Documents; Delivery Dates.  (a)
The Trustee is hereby directed (i) to execute and deliver the Intercreditor
Agreement, the Escrow Agreement and the Note Purchase Agreement on or prior to
the Issuance Date, each in the form delivered to the Trustee by the Company and
(ii) subject to the respective terms thereof, to perform its obligations
thereunder.  Upon request of the Company and the satisfaction or waiver of the
closing conditions specified in the Placement Agreement, the Trustee shall
execute, deliver, authenticate, issue and sell Certificates in authorized
denominations equaling in the aggregate the amount set forth, with respect to
the Trust, in Schedule II to the Placement Agreement evidencing the entire
ownership interest in the Trust, which amount equals the maximum aggregate
principal amount of Equipment Notes which may be purchased by the Trustee
pursuant to the Note Purchase Agreement.  Except as provided in Sections 3.04
and 3.07 of this Agreement, the Trustee shall not execute, authenticate or
deliver Certificates in excess of the aggregate amount specified in this
paragraph.

                 (b)      On or after the Issuance Date, the Company may
deliver from time to time to the Trustee a Delivery Notice relating to one or
more Equipment Notes.  After receipt of a Delivery Notice and in any case no
later than one Business Day prior to a Delivery Date as to which such Delivery
Notice relates (the "Applicable Delivery Date"), the Trustee shall (as and when
specified in the Delivery Notice) instruct the Escrow Agent to provide a Notice
of Purchase Withdrawal to the Depositary requesting (A) the withdrawal of one
or more Deposits on the Applicable Delivery Date in accordance with and to the
extent permitted by the terms of the Escrow Agreement and the Deposit Agreement
and (B) the payment of all, or a portion, of such Deposit or Deposits in an
amount equal in the aggregate to the purchase price of such Equipment Notes to
or on behalf of the Owner Trustee or the Company, as the case may be, issuing
such Equipment Notes, all as shall be described in the Delivery Notice.  The
Trustee shall (as and when specified in such Delivery Notice), subject to the
conditions set forth in Section 2 of the Note Purchase Agreement, enter into
and perform its obligations under the Participation Agreement specified in such
Delivery Notice (the "Applicable Participation Agreement") and cause such
certificates, documents and legal opinions relating to the Trustee to be duly
delivered as required by the Applicable Participation Agreement.  If at any
time prior to the Applicable Delivery Date, the Trustee receives a notice of
postponement pursuant to Section 1(e) or 1(f) of the Note Purchase Agreement,
then the Trustee shall give the Depositary (with a copy to the Escrow Agent) a
notice of cancellation of such Notice of Purchase Withdrawal relating to such
Deposit or Deposits on such Applicable Delivery Date.  Upon satisfaction of the
conditions specified in the Note Purchase Agreement and the Applicable
Participation Agreement, the Trustee shall
<PAGE>   25
                                       19

purchase the applicable Equipment Notes with the proceeds of the withdrawals of
one or more Deposits made on the Applicable Delivery Date in accordance with
the terms of the Deposit Agreement and the Escrow Agreement.  The purchase
price of such Equipment Notes shall equal the principal amount of such
Equipment Notes.  Amounts withdrawn from such Deposit or Deposits in excess of
the purchase price of the Equipment Notes or to the extent not applied on the
Applicable Delivery Date to the purchase price of the Equipment Notes, shall be
re-deposited by the Trustee with the Depositary on the Applicable Delivery Date
in accordance with the terms of the Deposit Agreement.

                 Section 2.02.  Withdrawal of Deposits.  If any Deposits remain
outstanding on the Business Day next succeeding the Cut-off Date, (i) the
Trustee shall give the Escrow Agent notice that the Trustee's obligation to
purchase Equipment Notes under the Note Purchase Agreement has terminated and
instruct the Escrow Agent to provide a notice of Final Withdrawal to the
Depositary substantially in the form of Exhibit B to the Deposit Agreement (the
"Final Withdrawal Notice") and (ii) the Trustee will make a demand upon the
Company under the Note Purchase Agreement for an amount equal to the Special
Redemption Premium, such payment to be made on the Final Withdrawal Date.

                 Section 2.03.  Acceptance by Trustee.  The Trustee, upon the
execution and delivery of this Agreement, acknowledges its acceptance of all
right, title and interest in and to the Trust Property and will hold such
right, title and interest for the benefit of all then present and future
Certificateholders, upon the trusts herein set forth.  By its payment for and
acceptance of each Certificate issued to it under this Agreement, each initial
Holder of such Certificate as grantor of such Trust shall thereby join in the
creation and declaration of such Trust.

                 Section 2.04.  Limitation of Powers.  The Trust is constituted
solely for the purpose of making the investment in the Equipment Notes, and,
except as set forth herein, the Trustee shall not be authorized or empowered to
acquire any other investments or engage in any other activities and, in
particular, the Trustee shall not be authorized or empowered to do anything
that would cause such Trust to fail to qualify as a "grantor trust" for federal
income tax purposes (including, as subject to this restriction, acquiring any
Aircraft (as defined in the respective Indentures) by bidding such Equipment
Notes or otherwise, or taking any action with respect to any such Aircraft once
acquired).

the face of the Certificate.

                 (b)      The Initial Certificates shall be issued only in
fully registered form without coupons and only in denominations of $100,000 or

Rule 144A shall be issued initially in the form of a single permanent global
Certificate in registered form, substantially in the form set forth as Exhibit
A hereto (the "U.S. Global Certificate"), duly executed and authenticated by
the Trustee as hereinafter provided.  The U.S. Global Certificate will be
registered in the name of a nominee for the Depositary and deposited with the
Trustee, as custodian for the Depositary.  The aggregate principal amount of
the U.S. Global Certificate may from time to time be increased or decreased by
adjustments made on the records of the Depositary or its nominee, or of the
Trustee, as custodian for the Depositary or its nominee, as hereinafter
provided.

                 (d)      Initial Certificates offered and sold in offshore
transactions in reliance on Regulation S shall be issued initially in the form
of a single temporary global Certificate in registered form, substantially in
the form set forth as Exhibit A hereto (the "Temporary Offshore Global

Trustee as custodian for the
<PAGE>   27
                                       21

Depositary.  At any time following March 21, 1998 (the "Offshore Certificates
Exchange Date"), upon receipt by the Trustee of a certificate substantially in
the form of Exhibit B hereto, a single permanent global Certificate in
registered form substantially in the form set forth in Exhibit A (the
"Permanent Offshore Global Certificate"; and together with the Temporary
Offshore Global Certificate, the "Offshore Global Certificates"), duly executed
and authenticated by the Trustee as hereinafter provided, shall be registered
in the name of a nominee for the Depositary and deposited with the Trustee, as
custodian for the Depositary, and the Registrar shall reflect on its books and
records the date of such transfer and a decrease in the principal amount of any
Temporary Offshore Global Certificate in an amount equal to the principal
amount of the beneficial interest in such Temporary Offshore Global Certificate
transferred.  The U.S. Global Certificate and the Offshore Global Certificates
are sometimes referred to as the "Global Certificates".

                 (e)      Initial Certificates offered and sold to
Institutional Accredited Investors shall be issued in the form of permanent
certificated Certificates in registered form in substantially the form set

issued pursuant to Section 3.05(b) in exchange for interests in any Offshore

of one or more global Certificates substantially in the form of Exhibit A
hereto (each, a "Global Exchange Certificate"), except that (i) the Private
Placement Legend (hereinafter defined) shall be omitted and (ii)  such Exchange
Certificates shall contain such appropriate insertions, omissions,
substitutions and other variations from the form set forth in Exhibit A hereto
relating to the nature of the Exchange Certificates as the Responsible Officer
of the Trustee executing such Exchange Certificates on behalf of the Trust may
determine, as evidenced by such officer's execution on behalf of the Trust of
such Exchange Certificates.  Such Global Exchange Certificates shall be in
registered form and be registered in the name of DTC and deposited with the
Trustee, at its Corporate Trust Office, as custodian for DTC.  The aggregate
principal amount of any Global Exchange Certificate may from time to time be
increased or decreased by adjustments made on the records of the Trustee, as
custodian for DTC for such Global Exchange Certificate, which adjustments shall
be conclusive as to the aggregate principal amount of any such Global Exchange
Certificate.  Subject to clause (i) and (ii)  of the first sentence of this
Section 3.01(f), the terms hereof applicable to Restricted Global Certificates
and/or Global Certificates shall apply to the Global Exchange Certificates,
mutatis mutandis.

form and shall be typed, printed, lithographed or engraved or produced by any

Registration Statement or (ii) an Initial Certificate is exchanged for an

Statement, in each case as provided for in the Registration Rights Agreement,
each Global Certificate (other than the Permanent Offshore Global Certificate)
and each U.S. Physical Certificate shall bear the following legend (the
"Private Placement Legend") on the face thereof:

                 THIS CERTIFICATE HAS NOT BEEN REGISTERED UNDER THE U.S.
         SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND
         ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR
         TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY PERSONS EXCEPT AS SET FORTH
         IN THE FOLLOWING SENTENCE.  BY ITS ACQUISITION HEREOF, THE HOLDER (1)
         REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS
         DEFINED IN RULE 144A UNDER THE SECURITIES ACT), (B) IT IS AN
         INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)(1),
         (2), (3) OR (7) OF REGULATION D UNDER THE SECURITIES ACT) (AN
         "INSTITUTIONAL ACCREDITED INVESTOR") OR (C) IT IS NOT A U.S.  PERSON
         AND IS ACQUIRING THIS CERTIFICATE IN AN OFFSHORE TRANSACTION IN
         COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT; (2) AGREES THAT
         IT WILL NOT WITHIN TWO YEARS AFTER THE LATER OF THE ORIGINAL ISSUANCE
         OF THIS CERTIFICATE OR THE LAST DATE ON WHICH THIS CERTIFICATE WAS
         HELD BY ATLAS AIR, INC., THE TRUSTEE OR ANY AFFILIATE OF ANY OF SUCH
         PERSONS RESELL OR OTHERWISE TRANSFER THIS CERTIFICATE EXCEPT (A) TO A
         QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE
         SECURITIES ACT, (B) INSIDE THE UNITED STATES TO AN INSTITUTIONAL
         ACCREDITED INVESTOR ACQUIRING $100,000 OR MORE AGGREGATE PRINCIPAL
         AMOUNT OF  SUCH CERTIFICATE THAT, PRIOR TO SUCH TRANSFER, FURNISHES TO
         THE TRUSTEE A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND
         AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THIS
         CERTIFICATE (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM THE
         TRUSTEE), (C) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN
         COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT, (D) PURSUANT TO THE

         EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT; AND (3)
         AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS CERTIFICATE IS
         TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.  IN
         CONNECTION WITH ANY TRANSFER OF THIS CERTIFICATE WITHIN TWO YEARS
         AFTER THE LATER OF THE ORIGINAL ISSUANCE OF THIS CERTIFICATE OR THE
         LAST DATE ON WHICH THIS CERTIFICATE WAS HELD BY ATLAS AIR, INC., THE
         TRUSTEE OR ANY AFFILIATE OF ANY OF SUCH PERSONS THE HOLDER MUST CHECK
         THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE
         MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO THE TRUSTEE.
         AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION", "UNITED STATES" AND
         "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER
         THE SECURITIES ACT.  THE PASS THROUGH TRUST AGREEMENT CONTAINS A
         PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF
         THIS CERTIFICATE IN VIOLATION OF THE FOREGOING RESTRICTIONS.

                 (b)      Each Global Certificate shall also bear the following
legend on the face thereof:

         UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE
         OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO
         THE TRUSTEE OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR

                 Section 3.03.  Authentication of Certificates.  (a)  On the
Issuance Date, the Trustee shall duly execute, authenticate and deliver
Certificates in authorized denominations equalling in the aggregate the amount
set forth, with respect to the Trust, in Schedule II to the Placement
Agreement, evidencing the entire ownership of the Trust, which amount equals
the maximum aggregate principal amount of the Equipment Notes which may be
purchased by the Trustee pursuant to the Note Purchase Agreement.

                 (b)      No Certificate shall be entitled to any benefit under
this Agreement or be valid or obligatory for any purpose, unless there appears
on such Certificate a certificate of authentication substantially in the form
provided for herein executed by the Trustee by the manual signature of one of
its authorized signatories, and such certificate upon any Certificate shall be
conclusive evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder.

                 Section 3.04.  Transfer and Exchange.  The Trustee shall cause
to be kept at the office or agency to be maintained by it in accordance with
the provisions of Section 7.12 of this Agreement a register (the "Register")
for the Certificates in which, subject to such reasonable regulations as it may
prescribe, the Trustee shall provide for the registration of the Certificates
and of transfers and exchanges of the Certificates as herein provided.  The
Trustee shall initially be the registrar (the "Registrar") for the purpose of
registering the Certificates and transfers and exchanges of the Certificates as
herein provided.  A Certificateholder may transfer a Certificate by written
application to the Registrar stating the name of the proposed transferee and
otherwise complying with the terms of this Agreement, including providing a
written certificate or other evidence of compliance with any restrictions on
transfer.  No such transfer shall be effected until, and such transferee shall
succeed to the rights of a Certificateholder only upon, final acceptance and
registration of the transfer by the Registrar in the Register.  Prior to the
registration of any transfer by a Certificateholder as provided herein, the
Trustee shall treat the person in whose name the Certificate is registered as
the owner thereof for all purposes, and the Trustee shall not be affected by
notice to the contrary.  Furthermore, the Depositary shall, by acceptance of a
Global Certificate, agree that transfers of beneficial interests in such Global
Certificate may be effected only through a book-entry system maintained by the
Depositary (or its agent), and that ownership of a beneficial interest in the
Certificate shall be required to be reflected in a book entry.  When
Certificates are presented to the Registrar with a request to register the
transfer or to exchange them for an equal face amount of Certificates of other
authorized denominations, the Registrar shall register the transfer or make the
exchange as requested if its requirements for such transactions are met.  To
permit registrations of transfers and exchanges in accordance with the terms,
conditions and restrictions hereof, the Trustee shall execute and authenticate
Certificates at the Registrar's request.  No service charge shall be made for
any registration of transfer or exchange of the Certificates, but the Trustee
may require payment by the transferor of a sum sufficient to cover any transfer
tax or similar governmental charge payable in connection therewith (other than
any such transfer taxes or
<PAGE>   31
                                       25

other similar governmental charges payable upon exchanges pursuant to Section
3.10 or 9.07).

                 Section 3.05.  Book-Entry Provisions for U.S. Global
Certificate and Offshore Global Certificates.  (a) Members of, or participants
in, the Depositary ("Agent Members") shall have no rights under this Agreement
with respect to any Global Certificate held on their behalf by the Depositary,
or the Trustee as its custodian, and the Depositary may be treated by the
Trustee and any agent of the Trustee as the absolute owner of such Global
Certificate for all purposes whatsoever.  Notwithstanding the foregoing,
nothing herein shall prevent the Trustee or any agent of the Trustee from
giving effect to any written certification, proxy or other authorization
furnished by the Depositary or shall 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 Certificate.  Upon the issuance of any Global
Certificate, the Registrar or its duly appointed agent shall record a nominee
of the Depositary as the registered holder of such Global Certificate.

                 (b)      Transfers of any Global Certificate shall be limited
to transfers of such Global Certificate or Offshore Global Certificate in
whole, but not in part, to nominees of the Depositary, its successor or such
successor's nominees.  Beneficial interests in the U.S. Global Certificate and
any Offshore Global Certificate may be transferred in accordance with the rules
and procedures of the Depositary and the provisions of Section 3.06.
Beneficial interests in the U.S. Global Certificate or an Offshore Global
Certificate shall be delivered to all beneficial owners in the form of U.S.
Physical Certificates or Offshore Physical Certificates, as the case may be, if
(i) the Depositary notifies the Trustee that it is unwilling or unable to
continue as Depositary for the U.S. Global Certificate or such Offshore Global
Certificate, as the case may be, and a successor depositary is not appointed by
the Trustee within 90 days of such notice or (ii) an Event of Default has
occurred and is continuing and the Registrar has received a request from the
Depositary to issue Physical Certificates.

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

                 (d)      In connection with the transfer of the entire U.S.
Global Certificate or an entire Offshore Global Certificate to the beneficial
owners thereof pursuant to paragraph (b) of this Section 3.05, such U.S. Global
Certificate or Offshore Global Certificate, as the case may be, shall be deemed
to be surrendered to the Trustee for cancellation, and the Trustee shall
execute, authenticate and deliver, to each beneficial owner identified by the
Depositary in exchange for its beneficial interest in such U.S. Global
Certificate or Offshore
<PAGE>   32
                                       26

Global Certificate, as the case may be, an equal aggregate principal amount of
U.S. Physical Certificates or Offshore Physical Certificates, as the case may
be, of authorized denominations.

                 (e)      Any U.S. Physical Certificate delivered in exchange
for an interest in the U.S. Global Certificate pursuant to paragraph (b) of
this Section 3.05 shall, except as otherwise provided by paragraph (f) of
Section 3.06, bear the Private Placement Legend.

                 (f)      Any Offshore Physical Certificate delivered in
exchange for an interest in an Offshore Global Certificate pursuant to
paragraph (b) of this Section shall, except as otherwise provided by paragraph
(f) of Section 3.06, bear the applicable legend regarding transfer restrictions
set forth in Section 3.02(a).

                 (g)      The registered holder of the U.S. Global Certificate
or any Offshore Global Certificate 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
Agreement or the Certificates.

                 Section 3.06.  Special Transfer Provisions.  Unless and until
(i) an Initial Certificate is sold under an effective Registration Statement,
or (ii) an Initial Certificate is exchanged for an Exchange Certificate
pursuant to an effective Exchange Offer Registration Statement, in each case
pursuant to the Registration Rights Agreement, the following provisions shall
apply to such Initial Certificates:

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

                          (i)     The Registrar shall register the transfer of
                 any Certificate, whether or not such Certificate bears the
                 Private Placement Legend, if (x) the requested transfer is at
                 least three years after the later of the original issue date
                 of the Certificates and the last date on which such
                 Certificate was held by the Company or any affiliate of any
                 such persons or (y) the proposed transferee has delivered to
                 the Registrar a letter substantially in the form of Exhibit D
                 hereto and the aggregate principal amount of the Certificates
                 being transferred is at least $100,000.

                          (ii)    If the proposed transferor is an Agent Member
                 holding a     beneficial interest in the U.S. Global
                 Certificate, 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
<PAGE>   33
                                       27

                 Registrar shall reflect on its books and records the date of
                 the transfer and a decrease in the principal amount of such
                 U.S. Global Certificate in an amount equal to the principal
                 amount of the beneficial interest in such U.S. Global
                 Certificate to be transferred, and the Company shall execute,
                 and the Trustee shall authenticate and deliver to the
                 transferor or at its direction, one or more U.S.  Physical
                 Certificates of like tenor and amount.

                 (b)      Transfers to QIBs.  The following provisions shall
         apply with respect to the registration of any proposed transfer of an
         Initial Certificate to a QIB (excluding Non-U.S. Persons):

                          (i)     If the Certificate to be transferred consists
                 of U.S. Physical  Certificates or an interest in any Temporary
                 Offshore Global Certificate, 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
                 Initial Certificate stating, or has otherwise advised the
                 Trustee 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 Initial Certificate stating, or has otherwise
                 advised the Trustee and the Registrar in writing, that it is
                 purchasing the Initial Certificate for its own account or an
                 account with respect to which it exercises sole investment
                 discretion and that it, or the Person on whose behalf it is
                 acting with respect to 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 Trust and/or 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.

                          (ii)    Upon receipt by the Registrar of the
                 documents referred to in clause (i) above and instructions
                 given in accordance with the Depositary's and the Registrar's
                 procedures therefor, the Registrar shall reflect on its books
                 and records the date of such transfer and an increase in the
                 principal amount of the U.S. Global Certificate in an amount
                 equal to the principal amount of the U.S.  Physical
                 Certificates or interests in the Temporary Offshore Global
                 Certificate, as the case may be, being transferred, and the
                 Trustee shall cancel such Physical Certificates or decrease
                 the amount of such Temporary Offshore Global Certificate so
                 transferred.

                 (c)      Transfers of Interests in the Permanent Offshore
Global Certificate or Offshore Physical Certificates.  The Registrar shall 
register any transfer of interests in
<PAGE>   34
                                       28

         the Permanent Offshore Global Certificate or Offshore Physical
         Certificates without requiring any additional certification.

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

                          (i)     Prior to the Offshore Certificates Exchange
                 Date, the Registrar shall register any proposed transfer of an
                 Initial Certificate to a Non-U.S. Person upon receipt of a
                 certificate substantially in the form set forth as Exhibit C
                 hereto from the proposed transferor.

                          (ii)    On and after the Offshore Certificates
                 Exchange Date, the Registrar shall register any proposed
                 transfer to any Non-U.S. Person if the Certificate to be
                 transferred is a U.S. Physical Certificate or an interest in
                 the U.S. Global Certificate, upon receipt of a certificate
                 substantially in the form of Exhibit C from the proposed
                 transferor.  The Registrar shall promptly send a copy of such
                 certificate to the Company.

                          (iii)   Upon receipt by the Registrar of (x) the
                 documents, if any, required by paragraph (ii) 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 of such transfer and a decrease in
                 the principal amount of such U.S. Global Certificate in an
                 amount equal to the principal amount of the beneficial
                 interest in such U.S. Global Certificate to be transferred,
                 and (B) 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 Certificate in an amount equal to the
                 principal amount of the U.S. Physical Certificate or the U.S.
                 Global Certificate, as the case may be, to be transferred, and
                 the Trustee shall cancel the Physical Certificate, if any, so
                 transferred or decrease the amount of such U.S. Global
                 Certificate.

                 (e)      Private Placement Legend.  Upon the transfer,
         exchange or replacement of Certificates not bearing the Private
         Placement Legend, the Registrar shall deliver Certificates that do not
         bear the Private Placement Legend.  Upon the transfer, exchange or
         replacement of Certificates bearing the Private Placement Legend, the
         Registrar shall deliver only Certificates that bear the Private
         Placement Legend unless either (i) the circumstances contemplated by
         paragraph (a)(i)(x) or (e)(ii) of this Section 3.06 exist or (ii)
         there is delivered to the Registrar an Opinion of Counsel to
<PAGE>   35
                                       29

         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 Certificate
         bearing the Private Placement Legend, each Holder of such a
         Certificate acknowledges the restrictions on transfer of such
         Certificate set forth in this Agreement and agrees that it will
         transfer such Certificate only as provided in this Agreement.  The
         Registrar shall not register a transfer of any Certificate unless such
         transfer complies with the restrictions on transfer of such
         Certificate set forth in this Agreement.  In connection with any
         transfer of Certificates, each Certificateholder agrees by its
         acceptance of the Certificates to furnish the Registrar or the Trustee
         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 the sufficiency of any
         such certifications, legal opinions or other information.

                 Until such time as no Certificates remain Outstanding, the
Registrar shall retain copies of all letters, notices and other written
communications received pursuant to Section 3.05 or this Section 3.06.  The
Trustee, if not the Registrar at such time, 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 3.07.  Mutilated, Destroyed, Lost or Stolen
Certificates.  If (a) any mutilated Certificate is surrendered to the Registrar
or the Registrar receives evidence to its satisfaction of the destruction, loss
or theft of any Certificate and (b) there is delivered to the Registrar and the
Trustee such security, indemnity or bond, as may be required by them to save
each of them harmless, then, in the absence of notice to the Registrar or the
Trustee that such destroyed, lost or stolen Certificate has been acquired by a
bona fide purchaser, and provided that the requirements of Section 8-405 of the
Uniform Commercial Code in effect in any applicable jurisdiction are met, the
Trustee shall execute, authenticate and deliver, in exchange for or in lieu of
any such mutilated, destroyed, lost or stolen Certificate, a new Certificate or
Certificates, in authorized denominations and of like Fractional Undivided
Interest and bearing a number not contemporaneously outstanding.

                 In connection with the issuance of any new Certificate under
this Section 3.07, the Trustee may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Trustee
and the Registrar) connected therewith.
<PAGE>   36
                                       30

                 Any duplicate Certificate issued pursuant to this Section 3.07
shall constitute conclusive evidence of the appropriate Fractional Undivided
Interest in the Trust, as if originally issued, whether or not the lost, stolen
or destroyed Certificate shall be found at any time.

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

                 Section 3.08.  Persons Deemed Owners.  Prior to due
presentment of a Certificate for registration of transfer, the Trustee, the
Registrar and any Paying Agent may treat the Person in whose name any
Certificate is registered (as of the day of determination) as the owner of such
Certificate for the purpose of receiving distributions pursuant to Article IV
and for all other purposes whatsoever, and none of the Trustee, the Registrar
or any Paying Agent shall be affected by any notice to the contrary.

                 Section 3.09.  Cancellation.  All Certificates surrendered for
payment or transfer or exchange shall, if surrendered to the Trustee or any
agent of the Trustee other than the Registrar, be delivered to the Registrar
for cancellation and shall promptly be cancelled by it.  No Certificates shall
be authenticated in lieu of or in exchange for any Certificates cancelled as
provided in this Section, except as expressly permitted by this Agreement.  All
cancelled Certificates held by the Registrar shall be destroyed and a
certification of their destruction delivered to the Trustee.

                 Section 3.10.  Temporary Certificates.  Until definitive
Certificates are ready for delivery, the Trustee shall authenticate temporary
Certificates.  Temporary Certificates shall be substantially in the form of
definitive Certificates but may have insertions, substitutions, omissions and
other variations determined to be appropriate by the officers executing the
temporary Certificates, as evidenced by their execution of such temporary
Certificates.  If temporary Certificates are issued, the Trustee will cause
definitive Certificates to be prepared without unreasonable delay.  After the
preparation of definitive Certificates, the temporary Certificates shall be
exchangeable for definitive Certificates upon surrender of the temporary
Certificates at the office or agency of the Trustee designated for such purpose
pursuant to Section 7.12, without charge to the Certificateholder.  Upon
surrender for cancellation of any one or more temporary Certificates, the
Trustee shall execute, authenticate and deliver in exchange therefor a like
face amount of definitive Certificates of authorized denominations.  Until so
exchanged, the temporary Certificates shall be entitled to the same benefits
under this Agreement as definitive Certificates.

                 Section 3.11.  Limitation of Liability for Payments.  All
payments and distributions made to Certificateholders shall be made only from
the Trust Property and only to the extent that the Trustee shall have
sufficient income or proceeds from the Trust
<PAGE>   37
                                       31

Property to make such payments in accordance with the terms of Article IV of
this Agreement.  Each Certificateholder, by its acceptance of a Certificate,
agrees that it will look solely to the income and proceeds from the Trust
Property for any payment or distribution due to such Certificateholder pursuant
to the terms of this Agreement and that it will not have any recourse to the
Company, the Trustee, the Loan Trustees, the Liquidity Providers, the Owner
Trustees or the Owner Participants, except as otherwise expressly provided
herein or in the Intercreditor Agreement.

                 The Company is a party to this Agreement solely for purposes
of meeting the requirements of the Trust Indenture Act, and therefore shall not
have any right, obligation or liability hereunder (except as otherwise
expressly provided herein).

                          DISTRIBUTIONS; STATEMENTS TO
                               CERTIFICATEHOLDERS

                 Section 4.01.  Certificate Account and Special Payments
Account.  (a)  The Trustee shall establish and maintain on behalf of the
Certificateholders a Certificate Account as one or more non-interest-bearing
accounts.  The Trustee shall hold such Certificate Account in trust for the
benefit of the Certificateholders, and shall make or permit withdrawals
therefrom only as provided in this Agreement.  On each day when a Scheduled
Payment is made to the Trustee under the Intercreditor Agreement with respect
to the Certificates, the Trustee, upon receipt thereof, shall immediately
deposit the aggregate amount of such Scheduled Payment in such Certificate
Account.

                 (b)      The Trustee shall establish and maintain on behalf of

which shall be non-interest bearing except as provided in Section 4.04. The
Trustee shall hold the Special Payments Account in trust for the benefit of the

made to the Trustee under the Intercreditor Agreement and upon payment of the

with respect to the Certificates, the Trustee, upon receipt thereof, shall
immediately deposit the aggregate amount of such Special Payments in such

                 (c)      The Trustee shall present (or, if applicable, cause

                 Section 4.02.  Distributions from Certificate Account and
Special Payments Account.  (a)  On each Regular Distribution Date with respect
to a series of Certificates or as soon thereafter as the Trustee has confirmed
receipt of the payment of all or any part of the Scheduled Payments due on the
Equipment Notes held (subject to the Intercreditor Agreement) in the related
Trust on such date, the Trustee shall distribute out of the applicable
Certificate Account the entire amount deposited therein pursuant to Section
4.01(a).  There shall be so distributed to each Certificateholder of record of
such series on the Record Date with respect to such Regular Distribution Date
(other than as provided in Section 11.01 concerning the final distribution) by
check mailed to such Certificateholder, at the address appearing in the
Register, such Certificateholder's pro rata share (based on the Fractional
Undivided Interest in the Trust held by such Certificateholder) of the total
amount in the applicable Certificate Account, except that, with respect to
Certificates registered on the Record Date in the name of a Clearing Agency (or
its nominee), such distribution shall be made by wire transfer in immediately
available funds to the account designated by such Clearing Agency (or such
nominee).

                 (b)      On each Special Distribution Date with respect to any
Special Payment with respect to the Certificates or as soon thereafter as the
Trustee has confirmed receipt of any Special Payments due on the Equipment
Notes held (subject to the Intercreditor Agreement) in the related Trust or
realized upon the sale of such Equipment Notes or receipt of the Special
Redemption Premium, the Trustee shall distribute out of the applicable Special
Payments Account the entire amount of such applicable Special Payment deposited
therein pursuant to Section 4.01(b).  There shall be so distributed to each
Certificateholder of record of such series on the Record Date with respect to
such Special Distribution Date (other than as provided in Section 11.01
concerning the final distribution) by check mailed to such Certificateholder,
at the address appearing in the Register, such Certificateholder's pro rata
share (based on the Fractional Undivided Interest in the related Trust held by
such Certificateholder) of the total amount in the applicable Special Payments
Account on account of such Special Payment, except that, with respect to
Certificates registered on the Record Date in the name of a Clearing Agency (or
its nominee), such distribution shall be made by wire transfer in immediately
available funds to the account designated by such Clearing Agency (or such
nominee).

                 (c)      The Trustee shall, at the expense of the Company,
cause notice of each Special Payment with respect to a series of Certificates
to be mailed to each Certificateholder at his address as it appears in the
Register.  In the event of redemption or purchase of Equipment Notes held in
the related Trust, such notice shall be mailed not less than 15 days prior to
the Special Distribution Date for the Special Payment resulting from such
redemption or purchase, which Special Distribution Date shall be the date of
such redemption or
<PAGE>   39
                                       33

purchase.  In the event that any Special Redemption Premium is to be paid by
the Company to the Trustee under the Note Purchase Agreement, such notice shall
be mailed, together with the notice by the Escrow Paying Agent under Section
2.06 of the Escrow Agreement, not less than 20 days prior to the Special
Distribution Date for such amount, which Special Distribution Date shall be the
Final Withdrawal Date.  In the case of any other Special Payments, such notice
shall be mailed as soon as practicable after the Trustee has confirmed that it
has received funds for such Special Payment, stating the Special Distribution
Date for such Special Payment which shall occur not less than 15 days after the
date of such notice and as soon as practicable thereafter.  Notices mailed by
the Trustee shall set forth:

                 (i)      the Special Distribution Date and the Record Date
         therefor (except as otherwise provided in Section 11.01);

                 (ii)     the amount of the Special Payment for each $1,000
         face amount Certificate and the amount thereof constituting principal,
         premium, if any, and interest;

                 (iii)    the reason for the Special Payment; and

                 (iv)     if the Special Distribution Date is the same date as
         a Regular Distribution Date for the Certificates, the total amount to
         be received on such date for each $1,000 face amount Certificate.

If the amount of (i) premium, if any, payable upon the redemption or purchase
of an Equipment Note or (ii) the Special Redemption Premium, if any, has not
been calculated at the time that the Trustee mails notice of a Special Payment,
it shall be sufficient if the notice sets forth the other amounts to be
distributed and states that any premium received will also be distributed.

                 If any redemption of the Equipment Notes held in any Trust is
cancelled, the Trustee, as soon as possible after learning thereof, shall cause
notice thereof to be mailed to each Certificateholder at its address as it
appears on the Register.

                 Section 4.03.  Statements to Certificateholders.  (a)  On each
Regular Distribution Date and Special Distribution Date, the Trustee will

Special Redemption Premium, reflecting in part the information provided by the
Escrow Paying Agent under the Escrow Agreement).  Such statement shall set
forth (per $1,000 aggregate principal amount of Certificate as to (ii), (iii),
(iv) and (v) below) the following information:

         indicating the amount allocable to each source;

                 (ii)     the amount of such distribution under this Agreement
         allocable to principal and the amount allocable to premium (including
         the Special Redemption Premium), if any;

                 (iii)    the amount of such distribution under this Agreement
         allocable to interest;

                 (iv)     the amount of such distribution under the Escrow
         Agreement allocable to interest;

                 (v)      the amount of such distribution under the Escrow

                 (b)      Within a reasonable period of time after the end of
each calendar year but not later than the latest date permitted by law, the
Trustee shall furnish to each Person who at any time during such calendar year
was a Certificateholder of record a statement containing the sum of the amounts
determined pursuant to clauses (a)(i), (a)(ii), (a)(iii), (a)(iv) and (a)(v)
above with respect to the related Trust for such calendar year or, in the event
such Person was a Certificateholder of record during a portion of such calendar
year, for the applicable portion of such year, and such other items as are
readily available to the Trustee and which a Certificateholder shall reasonably
request as necessary for the purpose of such Certificateholder's preparation of
its federal income tax returns.  Such statement and such other items shall be
prepared on the basis of information supplied to the Trustee by the Clearing
Agency Participants and shall be delivered by the Trustee to such Clearing
Agency Participants to be available for forwarding by such Clearing Agency
Participants to the holders of interests in the Certificates in the manner

the names of all Clearing Agency Participants reflected on such Clearing
Agency's books as holding interests in the Certificates on such date.  The

         notify the purchasing Class C Certificateholder of such other Class C
         Certificateholder's desire to participate in such a purchase, then

         participate in such a purchase, then such other Class D
         Certificateholder shall lose its right to purchase the Certificates
         pursuant to this Section 6.01(b).

                 The purchase price with respect to the Certificates shall be
equal to the Pool Balance of the Certificates, together with accrued and unpaid
interest thereon to the date of such purchase, without premium, but including
any other amounts then due and payable to the Certificateholders under this
Agreement, the Intercreditor Agreement, the Escrow Agreement or any Note
Document or on or in respect of the Certificates; provided, however, that (i)
if such purchase occurs after the record date specified in Section 2.03(b) of
the Escrow Agreement relating to the distribution of unused Deposits and

the aggregate amount of unused Deposits and interest to be distributed under
the Escrow Agreement (which deducted amounts shall remain distributable to, and
may be retained by, the Certificateholder as of such Record Date) and (ii) if
such purchase occurs after a Record Date, such purchase price shall be reduced

Certificates which are senior to the securities held by such purchaser(s).
Each payment of the purchase price of the Certificates referred to in the first

such, Class C Certificateholder(s) or Class D Certificateholder(s), as the case
may be, of the purchase price set forth in the first sentence of this
paragraph, forthwith sell, assign, transfer and convey to the purchaser(s)

its own acts), all of the right, title, interest and obligation of such
Certificateholder in this Agreement, the Escrow Agreement, the Deposit

Documents and all Certificates and Escrow Receipts held by such
Certificateholder (excluding all right, title and interest under any of the

of affairs occurring prior to such sale) and the purchaser shall assume all of
such Certificateholder's obligations under this Agreement, the Escrow
Agreement, the Deposit Agreement, the Intercreditor Agreement, the Liquidity
Facilities, the Note Documents and all such Certificates and Escrow Receipts.

Certificateholders will be to deliver the

Certificates and (ii) if the purchaser(s) shall so request, such
Certificateholder will comply with all the provisions of Section 3.04 of this
Agreement to enable new Certificates to be issued to the purchaser in such
denominations as it shall request.  All charges and expenses in connection with
the issuance of any such new Certificates shall be borne by the purchaser
thereof.

         in their own absolute right without further accountability.

                 (b)      Receipt of Trustee Shall Discharge Purchaser.  The
         receipt of the Trustee making such sale shall be a sufficient
         discharge to any purchaser for his purchase money, and, after paying
         such purchase money and receiving such receipt, such purchaser or its
         personal representative or assigns shall not be obliged to see to the
         application of such purchase money, or be in any way answerable for
         any loss, misapplication or nonapplication thereof.

         collected by the Trustee upon any sale made either under the power of
         sale given by this Agreement or otherwise for the enforcement of this

and as trustee of an express trust, as holder of such Equipment Notes, to the
extent permitted by and in accordance with the terms of any related

premium, if any, or interest on any Equipment Note or to pay Rent under any
Lease in accordance with the applicable Indenture), shall be entitled and
empowered to institute any suits, actions or proceedings at law, in equity or
otherwise, for the collection of the sums so due and unpaid on such Equipment
Notes or under such Lease and may prosecute any such claim or proceeding to
judgment or final decree with respect to the whole amount of any such sums so
due and unpaid.

                 Section 6.04.  Control by Certificateholders.  Subject to
Section 6.03 and the Intercreditor Agreement, the Certificateholders holding
Certificates evidencing Fractional Undivided Interests aggregating not less

available to the Trustee with respect to the Trust or pursuant to the terms of
the Intercreditor Agreement, or exercising any trust or power conferred on the
Trustee under this Agreement or the Intercreditor Agreement, including any
right of the Trustee as Controlling Party under the Intercreditor Agreement or
as holder of the Equipment Notes held in the related Trust; provided, however,
that

                 (a)      such Direction shall not in the opinion of the
         Trustee be in conflict with any rule of law or with this Agreement and
         would not involve the Trustee in personal liability or expense,

                 (b)      the Trustee shall not determine that the action so
         directed would be unjustly prejudicial to the Certificateholders not
         taking part in such Direction, and

                 (c)      the Trustee may take any other action deemed proper
         by the Trustee which is not inconsistent with such Direction.

                 Section 6.05.  Waiver of Past Defaults.  Subject to any
related Intercreditor Agreement, the Certificateholders holding Certificates of
a series evidencing Fractional Undivided Interests aggregating not less than a
majority in interest in the Trust (i) may on behalf of all of the
Certificateholders waive any past Event of Default hereunder and its
consequences or (ii) if the Trustee is the Controlling Party, may direct the
Trustee to instruct the applicable Loan Trustee to waive any past Indenture
Event of Default under any related Indenture and its consequences, and thereby
annul any Direction given by such Certificateholders or the Trustee to such
Loan Trustee with respect thereto, except a default:

                 (a)      in the deposit of any Scheduled Payment or Special
         Payment under Section 4.01 or in the distribution of any payment under
         Section 4.02 on the Certificates, or
<PAGE>   47
                                       41

                 (b)      in the payment of the principal of (premium, if any)
         or interest on the Equipment Notes held in the Trust, or

                 (c)      in respect of a covenant or provision hereof which
         under Article IX hereof cannot be modified or amended without the
         consent of each Certificateholder holding an Outstanding Certificate
         of a series affected thereby.

Upon any such waiver, such default shall cease to exist with respect to the
Certificates and any Event of Default arising therefrom shall be deemed to have
been cured for every purpose and any direction given by the Trustee on behalf
of the Certificateholders to the relevant Loan Trustee shall be annulled with
respect thereto; but no such waiver shall extend to any subsequent or other
default or Event of Default or impair any right consequent thereon.  Upon any
such waiver, the Trustee shall vote the Equipment Notes issued under the
relevant Indenture to waive the corresponding Indenture Event of Default.

                 Section 6.06.  Right of Certificateholders to Receive Payments
Not to Be Impaired.  Anything in this Agreement to the contrary
notwithstanding, including, without limitation, Section 6.07 hereof, but
subject to the Intercreditor Agreement, the right of any Certificateholder to
receive distributions of payments required pursuant to Section 4.02 hereof on
the applicable Certificates when due, or to institute suit for the enforcement
of any such payment on or after the applicable Regular Distribution Date or
Special Distribution Date, shall not be impaired or affected without the
consent of such Certificateholder.

                 Section 6.07.  Certificateholders May Not Bring Suit Except
Under Certain Conditions.  A Certificateholder shall not have the right to
institute any suit, action or proceeding at law or in equity or otherwise with
respect to this Agreement, for the appointment of a receiver or for the
enforcement of any other remedy under this Agreement, unless:

                 (a)      such Certificateholder previously shall have given
         written notice to the Trustee of a continuing Event of Default;

                 (b)      Certificateholders holding Certificates evidencing
         Fractional Undivided Interests aggregating not less than 25% of the
         related Trust shall have requested the Trustee in writing to institute
         such action, suit or proceeding and shall have offered to the Trustee
         indemnity as provided in Section 7.03(e);

                 (c)      the Trustee shall have refused or neglected to
         institute any such action, suit or proceeding for 60 days after
         receipt of such notice, request and offer of indemnity; and
<PAGE>   48
                                       42

                 (d)      no direction inconsistent with such written request
         shall have been given to the Trustee during such 60-day period by
         Certificateholders holding Certificates evidencing Fractional
         Undivided Interests aggregating not less than a majority in interest
         in the Trust.

                 It is understood and intended that no one or more of the
Certificateholders shall have any right in any manner whatsoever hereunder or
under the related Trust Supplement or under the Certificates to (i) surrender,
impair, waive, affect, disturb or prejudice any property in the Trust Property
of the Trust, or the lien of any related Indenture on any property subject
thereto, or the rights of the Certificateholders or the holders of the
Equipment Notes, (ii) obtain or seek to obtain priority over or preference with
respect to any other such Certificateholder or (iii) enforce any right under
this Agreement, except in the manner herein provided and for the equal, ratable
and common benefit of all the Certificateholders subject to the provisions of
this Agreement.

                 Section 6.08.  Remedies Cumulative.  Every remedy given
hereunder to the Trustee or to any of the Certificateholders shall not be
exclusive of any other remedy or remedies, and every such remedy shall be
cumulative and in addition to every other remedy given hereunder or now or
hereafter given by statute, law, equity or otherwise.

                 Section 6.09.  Undertaking for Costs.  In any suit for the
enforcement of any right or remedy under this Agreement, or in any suit against
the Trustee for any action taken, suffered or omitted by it as Trustee, a court
may require any party litigant in such suit to file an undertaking to pay the
costs of such suit, and may assess costs against any such party litigant, in
the manner and to the extent provided in the Trust Indenture Act; provided,
however, that neither this Section 6.09 nor the Trust Indenture Act shall be
deemed to authorize any court to require such an undertaking or to make such an
assessment in any suit instituted by the Company.


                                  ARTICLE VII

                                  THE TRUSTEE

                 Section 7.01.  Certain Duties and Responsibilities.  (a)
Except during the continuance of an Event of Default in respect of a Trust, the
Trustee undertakes to perform such duties in respect of the Trust as are
specifically set forth in this Agreement, and no implied covenants or
obligations shall be read into this Agreement against the Trustee.

                 (b)      In case an Event of Default in respect of a Trust has
occurred and is continuing, the Trustee shall exercise such of the rights and
powers vested in it by this Agreement in respect of the Trust, and use the same
degree of care and skill in their
<PAGE>   49
                                       43

exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs.

                 (c)      No provision of this Agreement 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

                 (i)      this Subsection shall not be construed to limit the
         effect of Subsection (a) of this Section 7.01; and

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

                 (d)      Whether or not herein expressly so provided, every
provision of this Agreement relating to the conduct or affecting the liability
of or affording protection to the Trustee shall be subject to the provisions of
this Section 7.01.

                 Section 7.02.  Notice of Defaults.  As promptly as practicable
after, and in any event within 90 days after, the occurrence of any default (as
such term is defined below) hereunder known to the Trustee, the Trustee shall
transmit by mail to the Company, any Owner Trustees, the Owner Participants,
the Loan Trustees and the Certificateholders holding Certificates in accordance
with Section 313(c) of the Trust Indenture Act, notice of such default
hereunder known to the Trustee, unless such default shall have been cured or
waived; provided, however, that, except in the case of a default in the payment
of the principal, premium, if any, or interest on any Equipment 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 shall determine that
the withholding of such notice is in the interests of the Certificateholders.
For the purpose of this Section 7.02 in respect of any Trust, the term
"default" means any event that is, or after notice or lapse of time or both
would become, an Event of Default in respect of that Trust.

                 Section 7.03.  Certain Rights of Trustee.  Subject to the
provisions of Section 315 of the Trust Indenture Act:

                 (a)      the Trustee may rely and shall be protected in acting
         or refraining from acting in reliance upon any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture or other paper or document
         believed by it to be genuine and to have been signed or presented by
         the proper party or parties;
<PAGE>   50
                                       44

                 (b)      any request or direction of the Company mentioned
         herein shall be sufficiently evidenced by a Request;

                 (c)      whenever in the administration of this Agreement or
         the Intercreditor Agreement, 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 Officer's Certificate of the Company, any Owner
         Trustee or any Loan Trustee;

                 (d)      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;

                 (e)      the Trustee shall be under no obligation to exercise
         any of the rights or powers vested in it by this Agreement or the
         Intercreditor Agreement at the Direction of any of the
         Certificateholders pursuant to this Agreement or the Intercreditor
         Agreement, unless the Certificateholders shall have offered to the
         Trustee reasonable security or indemnity against the cost, expenses
         and liabilities which might be incurred by it in compliance with such
         Direction;

                 (f)      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 or other paper or document;

                 (g)      the Trustee may execute any of the trusts or powers
         under this Agreement or the Intercreditor Agreement or perform any
         duties under this Agreement or the Intercreditor Agreement 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 under this Agreement
         or the Intercreditor Agreement;

                 (h)      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 Certificateholders holding Certificates
         evidencing Fractional Undivided Interests aggregating not less than a
         majority in interest in the Trust relating to the time, method and
         place of conducting any proceeding for any remedy available to the
         Trustee, or exercising any trust or power conferred upon the Trustee,
         under this Agreement or the Intercreditor Agreement; and
<PAGE>   51
                                       45

                 (i)      the Trustee shall not be required to expend or risk
         its own funds in the performance of any of its duties under this
         Agreement, 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 is not reasonably
         assured to it.

                 Section 7.04.  Not Responsible for Recitals or Issuance of
Certificates.  The recitals contained herein and in the Certificates, except
the certificates of authentication, shall not be taken as the statements of the
Trustee, and the Trustee assumes no responsibility for their correctness.
Subject to Section 7.15, the Trustee makes no representations as to the
validity or sufficiency of this Agreement, any Equipment Notes, the
Intercreditor Agreement, the Deposit Agreement, the Escrow Agreement, the
Certificates, or any Note Documents, except that the Trustee hereby represents
and warrants that this Agreement has been, and the Registration Rights
Agreement, each Certificate, the Note Purchase Agreement, the Escrow Agreement
and the Intercreditor Agreement will be, executed and delivered by one of its
officers who is duly authorized to execute and deliver such document on its
behalf.

                 Section 7.05.  May Hold Certificates.  The Trustee, any Paying
Agent, Registrar or any of their Affiliates or any other agent, in their
respective individual or any other capacity, may become the owner or pledgee of
Certificates and, subject to Sections 310(b) and 311 of the Trust Indenture
Act, if applicable, may otherwise deal with the Company, any Owner Trustees or
the Loan Trustees with the same rights it would have if it were not Trustee,
Paying Agent, Registrar or such other agent.

                 Section 7.06.  Money Held in Trust.  Money held by the Trustee
or the Paying Agent in trust under this Agreement need not be segregated from
other funds except to the extent required herein or by law and neither the
Trustee nor the Paying Agent shall have any liability for interest upon any
such moneys except as provided for herein.

                 Section 7.07.  Compensation and Reimbursement.  The Company
agrees:

                 (a)      to pay, or cause to be paid, to the Trustee from time
         to time  reasonable compensation for all services rendered by it
         hereunder (which compensation shall not be limited by any provision of
         law in regard to the compensation of a trustee of an express trust);
         and

                 (b)      to reimburse, or cause to be reimbursed, the Trustee
         upon its request for all reasonable out- of-pocket expenses,
         disbursements and advances incurred or made by the Trustee in
         accordance with any provision of this Agreement or the Intercreditor
         Agreement (including the reasonable compensation and the expenses and
         disbursements of its agents and counsel), except any such expense,
         disbursement or advance as may be attributable to its negligence,
         willful misconduct or bad faith or as
<PAGE>   52
                                       46

         may be incurred due to the Trustee's breach of its representations and
         warranties set forth in Section 7.15; and

                 (c)      to indemnify the Trustee with respect to the
         Certificates, pursuant to Section 8.1 of the Owned Aircraft
         Participation Agreements and Section 9.1 of the Leased Aircraft
         Participation Agreements, as the case may be.

                 The Trustee shall be entitled to reimbursement from, and shall
have a lien prior to the Certificates upon, all property and funds held or
collected by the Trustee in its capacity as Trustee for any tax incurred
without negligence, bad faith or willful misconduct, on its part, arising out
of or in connection with the acceptance or administration of the Trust (other
than any tax attributable to the Trustee's compensation for serving as such),
including any costs and expenses incurred in contesting the imposition of any
such tax.  The Trustee shall notify the Company of any claim for any tax for
which it may seek reimbursement.  If the Trustee reimburses itself from the
Trust Property of such Trust for any such tax, it will mail a brief report
within 30 days setting forth the amount of such tax and the circumstances
thereof to all Certificateholders as their names and addresses appear in the
Register.

                 Section 7.08.  Corporate Trustee Required; Eligibility.  The
Trust shall at all times have a Trustee which shall be eligible to act as a
trustee under Section 310(a) of the Trust Indenture Act and shall have a
combined capital and surplus of at least $75,000,000 (or a combined capital and
surplus in excess of $5,000,000 and the obligations of which, whether now in
existence or hereafter incurred, are fully and unconditionally guaranteed by a
corporation organized and doing business under the laws of the United States,
any state or territory thereof or of the District of Columbia and having a
combined capital and surplus of at least $75,000,000).  If such corporation
publishes reports of conditions at least annually, pursuant to law or to the
requirements of federal, state, territorial or District of Columbia supervising
or examining authority, then for the purposes of this Section 7.08 the combined
capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of conditions so
published.

                 In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 7.08 to act as Trustee of the
Trust, the Trustee shall resign immediately as Trustee of the Trust in the
manner and with the effect specified in Section 7.09.

                 Section 7.09.  Resignation and Removal; Appointment of
Successor.  (a)  No resignation or removal of the Trustee and no appointment of
a successor Trustee of the Trust pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee under
Section 7.10.
<PAGE>   53
                                       47

                 (b)      The Trustee may resign at any time as Trustee of the
Trust by giving prior written notice thereof to the Company, the Authorized
Agents, the Owner Trustees and the Loan Trustees.  If an instrument of
acceptance by a successor Trustee shall not have been delivered to the Company,
the Owner Trustees and the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

                 (c)      The Trustee may be removed at any time by Direction
of the Certificateholders holding Certificates evidencing Fractional Undivided
Interests aggregating not less than a majority in interest in such Trust
delivered to the Trustee and to the Company, the Owner Trustees and the Loan
Trustees.

                 (d)      If at any time in respect of the Trust:

                 (i)      the Trustee shall fail to comply with Section 310 of
         the Trust Indenture Act, if applicable, after written request therefor
         by the Company or by any Certificateholder who has been a bona fide
         Certificateholder for at least six months; or

                 (ii)     the Trustee shall cease to be eligible under Section
         7.08 and shall fail to resign after written request therefor by the
         Company or by any such Certificateholder; or

                 (iii)    the Trustee shall become incapable of acting or shall
         be adjudged a bankrupt or insolvent, or a receiver of the Trustee or
         of its property shall be appointed or any public officer shall take
         charge or control of the Trustee or of its property or affairs for the
         purpose of rehabilitation, conservation or liquidation;

then, in any case, (i) the Company may remove the Trustee or (ii) any
Certificateholder who has been a bona fide Certificateholder for at least six
months may, on behalf of itself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee of the Trust.

                 (e)      If a Responsible Officer of the Trustee shall obtain
actual knowledge of an Avoidable Tax (as defined below) in respect of any Trust
which has been or is likely to be asserted, the Trustee shall promptly notify
the Company and shall, within 30 days of such notification, resign as Trustee
of such Trust hereunder unless within such 30-day period the Trustee shall have
received notice that the Company has agreed to pay such tax.  The Company shall
promptly appoint a successor Trustee of such Trust in a jurisdiction where
there are no Avoidable Taxes.  As used herein, an "Avoidable Tax" in respect of
such Trust means a state or local tax:  (i) upon (w) such Trust, (x) such Trust
Property, (y) Certificateholders of the Trust or (z) the Trustee for which the
Trustee is entitled to seek
<PAGE>   54
                                       48

reimbursement from the Trust Property of such Trust, and (ii) which would be
avoided if the Trustee were located in another state, or jurisdiction within a
state, within the United States of America.  A tax shall not be an Avoidable
Tax in respect of any Trust if the Company or any Owner Trustee shall agree to
pay, and shall pay, such tax.

                 (f)      If the Trustee shall resign, be removed or become
incapable of acting as Trustee of the Trust or if a vacancy shall occur in the
office of the Trustee of the Trust for any cause, the Company shall promptly
appoint a successor Trustee.  If, within one year after such resignation,
removal or incapability, or other occurrence of such vacancy, a successor
Trustee shall be appointed by Direction of the Certificateholders holding
Certificates evidencing Fractional Undivided Interests aggregating not less
than a majority in interest in such Trust delivered to the Company, the Owner
Trustees, the Loan Trustee and the retiring Trustee, then the successor Trustee
so appointed shall, with the approval of the Company of such appointment, which
approval shall not be unreasonably withheld, forthwith upon its acceptance of
such appointment, become the successor Trustee and supersede the successor
Trustee appointed as provided above.  If no successor Trustee shall have been
so appointed as provided above and accepted appointment in the manner
hereinafter provided, the resigning Trustee or any Certificateholder who has
been a bona fide Certificateholder of the related series for at least six
months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the appointment of a successor Trustee.

                 (g)      The successor Trustee shall give notice of the
resignation and removal of the Trustee and appointment of the successor Trustee
by mailing written notice of such event by first-class mail, postage prepaid,
to the Certificateholders as their names and addresses appear in the Register.
Each notice shall include the name of such successor Trustee and the address of
its Corporate Trust Office.

                 Section 7.10.  Acceptance of Appointment by Successor.  Every
successor Trustee appointed hereunder shall execute and deliver to the Company
and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on request of the Company or the successor
Trustee, such retiring Trustee shall execute and deliver an instrument
transferring to such successor Trustee all such rights, powers and trusts of
the retiring Trustee and shall duly assign, transfer and deliver to such
successor Trustee all Trust Property held by such retiring Trustee, subject
nevertheless to its lien, if any, provided for in Section 7.07.  Upon request
of any such successor Trustee, the Company, the retiring Trustee and such
successor Trustee shall execute and deliver any and all instruments containing
such provisions as shall be necessary or desirable to transfer and confirm to,
and for more fully and certainly vesting in, such successor Trustee all such
rights, powers and trusts.
<PAGE>   55
                                       49


                 No institution shall accept its appointment as a Trustee
hereunder unless at the time of such acceptance such institution shall be
qualified and eligible under this Article VII.

                 Section 7.11.  Merger, Conversion, Consolidation or Succession
to Business.  Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder;
provided, however, that such corporation shall be otherwise qualified and
eligible under this Article VII, without the execution or filing of any paper
or any further act on the part of any of the parties hereto.  In case any
Certificates shall have been executed or authenticated, but not delivered, by
the Trustee then in office, any successor by merger, conversion or
consolidation to such authenticating Trustee may adopt such execution or
authentication and deliver the Certificates so executed or authenticated with
the same effect as if such successor Trustee had itself executed or
authenticated such Certificates.

                 Section 7.12.  Maintenance of Agencies.  (a)  With respect to
each series of Certificates, there shall at all times be maintained an office
or agency in the location set forth in Section 12.04 where Certificates may be
presented or surrendered for registration of transfer or for exchange, and for
payment thereof, and where notices and demands, to or upon the Trustee in
respect of such Certificates or this Agreement may be served; provided,
however, that, if it shall be necessary that the Trustee maintain an office or
agency in another location with respect to the Certificates (e.g., the
Certificates shall be represented by Definitive Certificates and shall be
listed on a national securities exchange), the Trustee will make all reasonable
efforts to establish such an office or agency.  Written notice of the location
of each such other office or agency and of any change of location thereof shall
be given by the Trustee to the Company, any Owner Trustees, the Loan Trustees
(in the case of any Owner Trustee or Loan Trustee, at its address specified in
the Note Documents or such other address as may be notified to the Trustee) and
the Certificateholders.  In the event that no such office or agency shall be
maintained or no such notice of location or of change of location shall be
given, presentations and demands may be made and notices may be served at the
Corporate Trust Office of the Trustee.

                 (b)      There shall at all times be a Registrar and a Paying
Agent hereunder with respect to the Certificates.  Each such Authorized Agent
shall be a bank or trust company, shall be a corporation organized and doing
business under the laws of the United States or any state, with a combined
capital and surplus of at least $75,000,000, or a corporation having a combined
capital and surplus in excess of $5,000,000, the obligations of which are
guaranteed by a corporation organized and doing business under the laws of the
United States or any state, with a combined capital and surplus of at least
$75,000,000, and shall be authorized under such laws to exercise corporate
trust powers, subject to supervision by federal or state authorities.  The
Trustee shall initially be the Paying Agent and, as
<PAGE>   56
                                       50

provided in Section 3.04, Registrar hereunder with respect to the Certificates.
Each Registrar shall furnish to the Trustee, at stated intervals of not more
than six months, and at such other times as the Trustee may request in writing,
a copy of the Register maintained by such Registrar.

                 (c)      Any corporation into which any Authorized Agent may
be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, consolidation or conversion to which any Authorized
Agent shall be a party, or any corporation succeeding to the corporate trust
business of any Authorized Agent, shall be the successor of such Authorized
Agent, if such successor corporation is otherwise eligible under this Section
7.12, without the execution or filing of any paper or any further act on the
part of the parties hereto or such Authorized Agent or such successor
corporation.

                 (d)      Any Authorized Agent may at any time resign by giving
written notice of resignation to the Trustee, the Company, any Owner Trustees
and the Loan Trustees.  The Company may, and at the request of the Trustee
shall, at any time terminate the agency of any Authorized Agent by giving
written notice of termination to such Authorized Agent and to the Trustee.
Upon the resignation or termination of an Authorized Agent or in case at any
time any such Authorized Agent shall cease to be eligible under this Section
7.12 (when, in either case, no other Authorized Agent performing the functions
of such Authorized Agent shall have been appointed), the Company shall promptly
appoint one or more qualified successor Authorized Agents, reasonably
satisfactory to the Trustee, to perform the functions of the Authorized Agent
which has resigned or whose agency has been terminated or who shall have ceased
to be eligible under this Section 7.12.  The Company shall give written notice
of any such appointment made by it to the Trustee, any Owner Trustees and the
Loan Trustees; and in each case the Trustee shall mail notice of such
appointment to all Certificateholders as their names and addresses appear on
the Register for such series.

                 (e)      The Company agrees to pay, or cause to be paid, from
time to time to each Authorized Agent reasonable compensation for its services
and to reimburse it for its reasonable expenses.

Trust.  All moneys deposited with any Paying Agent for the purpose of any
payment on Certificates shall be deposited and held in trust for the benefit of
the Certificateholders entitled to such payment, subject to the provisions of
this Section 7.13. Moneys so deposited and held in trust shall constitute a
separate trust fund for the benefit of the Certificateholders with respect to
which such money was deposited.

                 The Trustee may at any time, for the purpose of obtaining the
satisfaction and discharge of this Agreement or for any other purpose, direct
any Paying Agent to pay to the Trustee all sums held in trust by such Paying
Agent, such sums to be held by the Trustee
<PAGE>   57
                                       51

upon the same trusts as those upon which such sums were held by such Paying
Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying
Agent shall be released from all further liability with respect to such money.

                 Section 7.14.  Registration of Equipment Notes in Trustee's
Name.  Subject to the provisions of any Intercreditor Agreement, the Trustee
agrees that all Equipment Notes to be purchased by any Trust and Permitted
Investments, if any, shall be issued in the name of the Trustee as trustee for
the applicable Trust or its nominee and held by the Trustee in trust for the
benefit of the Certificateholders, or, if not so held, the Trustee or its
nominee shall be reflected as the owner of such Equipment Notes or Permitted
Investments, as the case may be, in the register of the issuer of such
Equipment Notes or Permitted Investments, as the case may be.

                 Section 7.15.  Representations and Warranties of Trustee.  The
Trustee hereby represents and warrants that:

                 (a)      the Trustee is a Delaware banking corporation

         contemplated herein or therein;

         action in respect of, any governmental authority or agency of the
         United States or the state of the United States where it is located
         regulating the banking and corporate trust activities of the Trustee;

         applicable bankruptcy, insolvency, reorganization, moratorium or

         general principles of equity.

thereto as required by law.  The Trustee agrees to act as such withholding
agent and, in connection therewith, whenever any present or future taxes or
similar charges are required to be withheld with respect to any amounts payable
in respect of the Certificates, to withhold such amounts and timely pay the
same to the appropriate authority in the name of and on behalf of the
Certificateholders, that it will file any necessary withholding tax returns or
statements when due, and that, as promptly as possible after the payment
thereof, it will deliver to each such Certificateholder appropriate
documentation showing the payment thereof, together with such additional
documentary evidence as such Certificateholders may reasonably request from
time to time.  The Trustee agrees to file any other information reports as it
may be required to file under United States law.

charge, encumbrance, security interest or claim ("Trustee's Liens") on or with
respect to the Trust Property of such Trust which is attributable to the
Trustee either (i) in its individual capacity and which is unrelated to the
transactions contemplated by this Agreement, the Intercreditor Agreement, the
Note Purchase Agreement or the Note Documents or (ii) as Trustee hereunder or

                   AMENDMENTS TO INDENTURE AND NOTE DOCUMENTS

                 Section 10.01.  Amendments and Supplements to Indenture and
Other Note Documents.  In the event that the Trustee, as holder (or beneficial
owner through the Subordination Agent) of any Equipment Notes (or as a
prospective purchaser of any Postponed Notes) in trust for the benefit of the
Certificateholders or as Controlling Party under an Intercreditor Agreement,
receives (directly or indirectly through the Subordination Agent) a request for
a consent to any amendment, modification, waiver or supplement under any
Indenture, other Note Document or any other related document, which request
would require the consent of Certificateholders under Section 9.02 hereof, the
Trustee shall forthwith send a notice of such proposed amendment, modification,
waiver or supplement to each Certificateholder registered on the Register as of
the date of such notice.  The Trustee shall request from the Certificateholders
a Direction as to (a) whether or not to take or refrain from taking (or direct
the Subordination Agent to take or refrain from taking) any action which a
holder of (or, with respect to Postponed Notes, a prospective purchaser of)
<PAGE>   65
                                       59

such Equipment Note or a Controlling Party has the option to direct, (b)
whether or not to give or execute (or direct the Subordination Agent to give or
execute) any waivers, consents, amendments, modifications or supplements as a
holder of (or, with respect to Postponed Notes, a prospective purchaser of)
such Equipment Note or as Controlling Party and (c) how to vote (or direct the
Subordination Agent to vote) any Equipment Note (or, with respect to a
Postponed Note, its commitment to acquire such Postponed Note) if a vote has
been called for with respect thereto.  Provided such a request for
Certificateholder Direction shall have been made, in directing any action or
casting any vote or giving any consent as the holder of any Equipment Note (or
in directing the Subordination Agent in any of the foregoing), (i) other than
as Controlling Party, the Trustee shall vote for or give consent to any such
action with respect to such Equipment Note (or Postponed Note) in the same
proportion as that of (A) the aggregate face amounts of all Certificates
actually voted in favor of or for giving consent to such action by such
Direction of Certificateholders to (B) the aggregate face amount of all
Outstanding Certificates and (ii) as Controlling Party, the Trustee shall vote
as directed in such Certificateholder Direction by the Certificateholders
evidencing a Fractional Undivided Interest aggregating not less than a majority
in interest in the Trust.  For purposes of the immediately preceding sentence,
a Certificate shall have been "actually voted" if the Holder of such
Certificate has delivered to the Trustee an instrument evidencing such Holder's
consent to such Direction prior to one Business Day before the Trustee directs
such action or casts such vote or gives such consent.  Notwithstanding the
foregoing, but subject to Section 6.04 and any Intercreditor Agreement, the
Trustee may, with respect to the Certificates, in its own discretion and at its
own direction, consent and notify the relevant Loan Trustee of such consent (or
direct the Subordination Agent to consent and notify the Loan Trustee of such
consent) to any amendment, modification, waiver or supplement under any related
Indenture or any other related Note Document if an Event of Default hereunder
shall have occurred and be continuing or if such amendment, modification,
waiver or supplement will not materially adversely affect the interests of the
Certificateholders.

                 enforceable against each such party in accordance with its
                 terms;

                          (b)     upon the execution and delivery of the
                 Assignment and Assumption Agreement in accordance with the

                 Company Act of 1940, as amended;

                          (d)     the Related Pass Through Trust Agreement
                 constitutes the valid and binding obligation of the Company
                 enforceable against the Company in accordance with its terms;
                 and

                 parties thereto of the transactions contemplated to be
                 consummated thereunder on the date thereof, will violate any
                 law or governmental rule or regulation of the State of New
                 York or the United States of America known to such counsel to
                 be applicable to the transactions contemplated by the
                 Assignment and Assumption Agreement.

         the Related Trustee with the Office of the Superintendent, State of
         New York Banking Department for the qualification of the Related
         Trustee under Section 131(3) of the New York Banking Law.

Upon the execution of the Assignment and Assumption Agreement by the parties
thereto, the Trust shall be terminated, the Certificateholders shall receive
beneficial interests in the Related Trust in exchange for their interests in
the Trust equal to their respective beneficial interests in the Trust, and the
Outstanding Certificates representing Fractional Undivided Interests in the
Trust shall be deemed for all purposes of this Agreement and the Related Pass
Through Trust Agreement, without further signature or action of any party or
Certificateholder, to be certificates representing the same fractional
undivided interests in the Related Trust and its trust property.  By acceptance
of its Certificate, each Certificateholder consents to such assignment,
transfer and delivery of the Trust Property to the trustee of the Related Trust
upon the execution and delivery of the Assignment and Assumption Agreement.

                 In connection with the occurrence of the event set forth in
clause (B) above, notice of such termination, specifying the Distribution Date
upon which the Certificateholders may surrender their Certificates to the
Trustee for payment of the final distribution and cancellation, shall be mailed
promptly by the Trustee to Certificateholders not earlier than the 60th day and
not later than the 15th day next preceding such final Distribution Date
specifying (A) the Distribution Date upon which the proposed final payment of
the Certificates will be made upon presentation and surrender of Certificates
at the office or agency of the Trustee therein specified, (B) the amount of any
such proposed final payment, and (c) that the Record Date otherwise applicable
to such Distribution Date is not applicable, payments being made only upon
presentation and surrender of the Certificates at the office or agency of the
Trustee therein specified.  The Trustee shall give such notice to the Registrar
at the time such notice is given to Certificateholders.  Upon presentation and
surrender of the Certificates in accordance with such notice, the Trustee shall
cause to be distributed to Certificateholders such final payments.

                                       62

                 In the event that all of the Certificateholders shall not
surrender their Certificates for cancellation within six months after the date
specified in the above-mentioned written notice, the Trustee shall give a
second written notice to the remaining Certificateholders to surrender their
Certificates for cancellation and receive the final distribution with respect
thereto.  No additional interest shall accrue on the Certificates after the
Distribution Date specified in the first written notice.  In the event that any
money held by the Trustee for the payment of distributions on the Certificates
shall remain unclaimed for two years (or such lesser time as the Trustee shall
be satisfied, after sixty days' notice from the Company, is one month prior to
the escheat period provided under applicable law) after the final distribution
date with respect thereto, the Trustee shall pay to each Loan Trustee the
appropriate amount of money relating to such Loan Trustee and shall give
written notice thereof to the related Owner Trustees, the Owner Participants
and the Company.

issued in the name of the Subordination Agent under the Intercreditor Agreement

                            [REVERSE OF CERTIFICATE]


                 The Certificates do not represent a direct obligation of, or
an obligation guaranteed by, or an interest in, the Company or the Trustee or
any of their affiliates.  The Certificates are limited in right of payment, all
as more specifically set forth on the face hereof and in the Agreement.  All
payments or distributions made to Certificateholders under the Agreement shall
be made only from the Trust Property and only to the extent that the Trustee
shall have sufficient income or proceeds from the Trust Property to make such
payments in accordance with the terms of the Agreement.  Each Certificateholder
of this Certificate, by its acceptance hereof, agrees that it will look solely
to the income and proceeds from the Trust Property to the extent available for
distribution to such Certificateholder as provided in the Agreement.  This
Certificate does not purport to summarize the Agreement and reference is made
to the Agreement for information with respect to the interests, rights,
benefits, obligations, proceeds, and duties evidenced hereby.  A copy of the
Agreement may be examined during normal business hours at the principal office
of the Trustee, and at such other places, if any, designated by the Trustee, by
any Certificateholder upon request.

                 The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Certificateholders under the
Agreement at any time by the Company and the Trustee with the consent of the
Certificateholders holding Certificates evidencing Fractional Undivided
Interests aggregating not less than a majority in interest in the Trust.  Any
such consent by the Certificateholder of this Certificate shall be conclusive
and binding on such Certificateholder and upon all future Certificateholders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange hereof or in lieu hereof whether or not notation of such consent is
made upon this Certificate.  The Agreement also permits the amendment thereof,
in certain limited circumstances, without the consent of the Certificateholders
of any of the Certificates.

                 As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Register upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee in its capacity as
Registrar, or by any successor Registrar, in the Borough of Manhattan, the City
of New York, duly endorsed or accompanied by a written instrument of transfer
in form satisfactory to the Trustee and the Registrar duly executed by the
Certificateholder hereof or such Certificateholder's attorney duly authorized
in writing, and thereupon one or more new Certificates of authorized
denominations evidencing the same aggregate Fractional Undivided Interest in
the Trust will be issued to the designated transferee or transferees.
<PAGE>   81
                                      A-9

                 The Certificates are issuable only as registered Certificates
without coupons in minimum denominations of [$100,000]* [$1,000]** Fractional
Undivided Interest and integral multiples of $1,000 in excess thereof [except
that one Certificate may be in a denomination of less than $100,000]*.  As
provided in the Agreement and subject to certain limitations therein set forth,
the Certificates are exchangeable for new Certificates of authorized
denominations evidencing the same aggregate Fractional Undivided Interest in
the Trust, as requested by the Certificateholder surrendering the same.

                 No service charge will be made for any such registration of
transfer or exchange, but the Trustee shall require payment by the Holder of a
sum sufficient to cover any tax or governmental charge payable in connection
therewith.

                 The Trustee, the Registrar, and any agent of the Trustee or
the Registrar may treat the person in whose name this Certificate is registered
as the owner hereof for all purposes, and neither the Trustee, the Registrar,
nor any such agent shall be affected by any notice to the contrary.

                 The obligations and responsibilities created by the Agreement
and the Trust created thereby shall terminate upon the distribution to
Certificateholders of all amounts required to be distributed to them pursuant
to the Agreement and the disposition of all property held as part of the Trust
Property.

Dear Sirs:

                 In connection with our proposed purchase of $_______________
aggregate principal amount of the Certificates, we confirm that:

                 1.       We understand that any subsequent transfer of the
         Certificates is subject to certain restrictions and conditions set
         forth in the Pass Through Trust Agreement dated as of February 9, 1998
         relating to the Certificates (the "Pass Through Trust Agreement") and
         the undersigned agrees to be bound by, and not to resell, pledge or
         otherwise transfer the Certificates except in compliance with, such
         restrictions and conditions and the Securities Act of 1933, as amended
         (the "Securities Act").

                 2.       We understand that the Certificates have not been
         registered under the Securities Act, and that the Certificates may not
         be offered or sold except as permitted in the following sentence.  We
         agree, on our own behalf and on behalf of any accounts for which we
         are acting as hereinafter stated, that if we should sell any
         Certificate, we will do so only (A) in accordance with Rule 144A under
         the Securities Act to a "qualified institutional buyer" (as defined
         therein), (B) to an institutional "accredited investor" (as defined
         below) that, prior to such transfer, furnishes to you and Continental
         Airlines, Inc., a signed letter substantially in the form of this
         letter, (C) outside the United States in accordance with Rule 904 of
         Regulation S under the Securities Act, (D) pursuant to the exemption
         from registration provided by Rule 144 under the Securities Act, or
         (E) pursuant to an effective registration statement under
<PAGE>   88
                                      D-2

         the Securities Act, and we further agree to provide to any person
         purchasing any of the Certificates from us a notice advising such
         purchaser that resales of the Notes are restricted as stated herein.
         We further understand that the Certificates purchased by us will bear
         a legend to the foregoing effect.

                 3.       We understand that, on any proposed resale of any
         Certificates, we will be required to furnish to you and Atlas Air,
         Inc. such certifications, legal opinions and other information as you
         and Atlas Air, Inc.  may reasonably require to confirm that the
         proposed sale complies with the foregoing restrictions.  We further
         understand that the Certificates purchased by us will bear a legend to
         the foregoing effect.

                 4.       We are an institutional "accredited investor" (as
         defined in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the
         Securities Act) and have such knowledge and experience in financial
         and business matters as to be capable of evaluating the merits and
         risks of our investment in the Certificates and we and any accounts
         for which we are acting are each able to bear the economic risk of our
         or its investment.

                 5.       We are acquiring the Certificates purchased by us for
         our own account or for one or more accounts (each of which is an
         institutional "accredited investor") as to each of which we exercise
         sole investment discretion.

                 You and Atlas Air, Inc. are entitled to rely upon this letter
and are irrevocably authorized to produce this letter or a copy hereof to any
interested party in any administrative or legal proceedings or official inquiry

therein and evidenced thereby) are herein sometimes referred to as the "Act" of
the Certificateholders signing such instrument or instruments.  Proof of
execution of any such instrument or of a writing appointing any such agent or
proxy shall be sufficient for any purpose of this Trust Agreement and
conclusive in favor of the Trustee, the Company and the related Loan Trustee,
if made in the manner provided in this Section 1.04.

                 (b)      The fact and date of the execution by any Person of
any such instrument or writing may be proved by the certificate of any notary
public or other officer of any jurisdiction authorized to take acknowledgments
of deeds or administer oaths that the Person executing such instrument
acknowledged to him the execution thereof, or by an affidavit of a witness to
such execution sworn to before any such notary or such other officer, and where
such execution is by an officer of a corporation or association or a member of
a partnership, on behalf of such corporation, association or partnership, such
certificate or affidavit shall also constitute sufficient proof of his
authority.  The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other reasonable manner which the Trustee deems sufficient.

                 (c)      In determining whether the Certificateholders of the
requisite Fractional Undivided Interests of Certificates Outstanding have given
any Direction under this Agreement, Certificates owned by the Company or any
Affiliate thereof shall be disregarded and deemed not to be Outstanding for
purposes of any such determination.  In determining whether the Trustee shall
be protected in relying upon any such Direction, only Certificates which the
Trustee knows to be so owned shall be so disregarded.  Notwithstanding the
foregoing, (i) if any such Person owns 100% of the Certificates Outstanding,
such Certificates shall not be so disregarded, and (ii) if any amount of
Certificates so owned by any such Person have been pledged in good faith, such
Certificates shall not be disregarded if the pledgee establishes to the
satisfaction of the Trustee the pledgee's right so to act with respect to such
Certificates and that the pledgee is not the Company or any Affiliate thereof.

                 (d)      The Company may, at its option, by delivery of an
Officer's Certificate to the Trustee, set a record date to determine the
Certificateholders in respect of the Certificates, entitled to give any
Direction.  Notwithstanding Section 316(c) of the Trust
<PAGE>   23
                                       17

Indenture Act, such record date shall be the record date specified in such
Officer's Certificate, which shall be a date not more than 30 days prior to the
first solicitation of Certificateholders of the applicable series in connection
therewith.  If such a record date is fixed, such Direction may be given before
or after such record date, but only the Certificateholders of record of the
applicable series at the close of business on such record date shall be deemed
to be Certificateholders for the purposes of determining whether
Certificateholders of the requisite proportion of Outstanding Certificates have
authorized or agreed or consented to such Direction, and for that purpose the
Outstanding Certificates shall be computed as of such record date; provided,
however, that no such Direction by the Certificateholders on such record date
shall be deemed effective unless it shall become effective pursuant to the
provisions of this Agreement not later than one year after such record date.

                 (e)      Any Direction by the Holder of any Certificate shall
bind the Holder of every Certificate issued upon the transfer thereof or in
exchange therefor or in lieu thereof, whether or not notation of such Direction
is made upon such Certificate.

                 (f)      Except as otherwise provided in Section 1.04(c),
Certificates owned by or pledged to any Person shall have an equal and
proportionate benefit under the provisions of this Agreement, without
preference, priority or distinction as among all of the Certificates.


                                   ARTICLE II

                       ACQUISITION OF THE TRUST PROPERTY

                 Section 2.01.    Acquisition of Trust Property.  The Trustee
is hereby irrevocably authorized and directed to execute and deliver the
Assignment and Assumption Agreement on the date specified in Section 11.01 of
the Related Pass Through Trust Agreement, subject only to the satisfaction of
the conditions set forth in said Section 11.01.  This Agreement (except only
for the immediately preceding sentence hereof, which is effective upon
execution and delivery hereof) shall become effective upon the execution and
delivery of the Assignment and Assumption Agreement by the Trustee and the
Related Trustee, automatically and without any further signature or action on
the part of the Company and the Trustee, and shall thereupon constitute the
legal, valid and binding obligation of the parties hereto enforceable against
each of the parties hereto in accordance with its terms.  Upon such execution
and delivery of the Assignment and Assumption Agreement, the Related Trust
shall be terminated, the Certificateholders shall receive beneficial interests
in the Trust in exchange for their interests in the Related Trust equal to
their respective beneficial interests in the Related Trust and the
"Outstanding" (as defined in the Related Pass Through Trust Agreement) pass
through certificates representing fractional undivided interests in the Related
Trust shall be deemed for all purposes of this Agreement,
<PAGE>   24
                                       18

without further signature or action of any party or Certificateholder, to be
Certificates representing the same Fractional Undivided Interests in the Trust
and Trust Property.  By acceptance of its Certificate, each Certificateholder
consents to and ratifies such assignment, transfer and delivery of the trust
property of the Related Trust to the Trustee upon the execution and delivery of
the Assignment and Assumption Agreement.

                 Section 2.02. [Intentionally omitted]

                 Section 2.03.  Acceptance by Trustee.  The Trustee, upon the
execution and delivery of the Assignment and Assumption Agreement, acknowledges
its acceptance of all right, title and interest in and to the Trust Property
and will hold such right, title and interest for the benefit of all then
present and future Certificateholders, upon the trusts herein set forth.  By
its payment for and acceptance of each Certificate issued under the Related
Pass Through Trust Agreement and deemed issued under this Agreement, each
Holder of such Certificate as grantor of such Trust thereby joins in the
creation and declaration of such Trust.

                 Section 2.04.  Limitation of Powers.  The Trust is constituted
solely for the purpose of making the investment in the Equipment Notes, and,
except as set forth herein, the Trustee shall not be authorized or empowered to
acquire any other investments or engage in any other activities and, in
particular, the Trustee shall not be authorized or empowered to do anything
that would cause such Trust to fail to qualify as a "grantor trust" for federal
income tax purposes (including, as subject to this restriction, acquiring any
Aircraft (as defined in the respective Indentures) by bidding such Equipment
Notes or otherwise, or taking any action with respect to any such Aircraft once
acquired).


                                  ARTICLE III

                                THE CERTIFICATES

                 Section 3.01.  Title, Form, Denomination and Execution of
Certificates.  (a)  The Initial Certificates shall be known as the "7.68%
1998-1B-S Initial Pass Through Certificates" and the Exchange Certificates
shall be known as the "7.68% 1998-1B-S Exchange Pass Through Certificates", in
each case, of the Trust.  Each Certificate will represent a fractional
undivided interest in the Trust and shall be substantially in the form set
forth as Exhibit A to the Related Pass Through Trust Agreement, with such
appropriate insertions, omissions, substitutions and other variations as are
required or permitted by the Related Pass Through Trust Agreement or by this
Agreement, as the case may be, or as the Trustee may deem appropriate, to
reflect the fact that the Certificates are being issued hereunder as opposed to
under the Related Pass Through Trust Agreement and may have such letters,
numbers or other marks of identification and such legends or endorsements
<PAGE>   25
                                       19

placed thereon as may be required to comply with the rules of any securities
exchange or as may, consistently herewith, be determined by the officers
executing such Certificates, as evidenced by their execution of the
Certificates.  Any portion of the text of any Certificate may be set forth on
the reverse thereof, with an appropriate reference thereto on the face of the
Certificate.

                 (b)      The Initial Certificates shall be issued only in
fully registered form without coupons and only in denominations of $100,000 or
integral multiples of $1,000 in excess thereof, except that one Certificate may
be issued in a denomination of less than $100,000.  The Exchange Certificates
will be issued in denominations of $1,000 or integral multiples thereof.  Each
Certificate shall be dated the date of its authentication.  The aggregate
Fractional Undivided Interest of Certificates initially deemed issued hereunder
shall not at any time exceed the aggregate principal amount of "Outstanding"
pass through trust certificates representing fractional undivided interests in
the Related Trust on the Transfer Date.

                 (c)      Initial Certificates offered and sold in reliance on
Rule 144A shall be issued initially in the form of a single permanent global
Certificate in registered form, substantially in the form set forth as Exhibit
A to the Related Pass Through Trust Agreement (the "U.S. Global Certificate"),
duly executed and authenticated by the Trustee as hereinafter provided.  The
U.S. Global Certificate will be registered in the name of a nominee for the
Depositary and deposited with the Trustee, as custodian for the Depositary.
The aggregate principal amount of the U.S. Global Certificate may from time to
time be increased or decreased by adjustments made on the records of the
Depositary or its nominee, or of the Trustee, as custodian for the Depositary
or its nominee, as hereinafter provided.

                 (d)      Initial Certificates offered and sold in offshore
transactions in reliance on Regulation S shall be issued initially in the form
of a single temporary global Certificate in registered form, substantially in
the form set forth as Exhibit A to the Related Pass Through Trust Agreement
(the "Temporary Offshore Global Certificate") duly executed and authenticated
by the Trustee as hereinafter provided.  The Temporary Offshore Global
Certificates will be registered in the name of a nominee of the Depositary for
credit to the account of the Agent Members acting as depositaries for Euroclear
and Cedel and deposited with the Trustee as custodian for the Depositary.  At
any time following March 21, 1998 (the "Offshore Certificates Exchange Date"),
upon receipt by the Trustee of a certificate substantially in the form of
Exhibit B to the Related Pass Through Trust Agreement, a single permanent
global Certificate in registered form substantially in the form set forth in
Exhibit A (the "Permanent Offshore Global Certificate"; and together with the
Temporary Offshore Global Certificate, the "Offshore Global Certificates"),
duly executed and authenticated by the Trustee as hereinafter provided, shall
be registered in the name of a nominee for the Depositary and deposited with
the Trustee, as custodian for the Depositary, and the Registrar shall reflect
on its books and records the date of such transfer and a decrease in the
principal
<PAGE>   26
                                       20

amount of any Temporary Offshore Global Certificate in an amount equal to the
principal amount of the beneficial interest in such Temporary Offshore Global
Certificate transferred.  The U.S. Global Certificate and the Offshore Global
Certificates are sometimes referred to as the "Global Certificates".

                 (e)      Initial Certificates offered and sold to
Institutional Accredited Investors shall be issued in the form of permanent
certificated Certificates in registered form in substantially the form set
forth as Exhibit A to the Related Pass Through Trust Agreement (the "U.S.
Physical Certificates").  Certificates issued pursuant to Section 3.05(b) in
exchange for interests in any Offshore Global Certificate shall be in the form
of permanent certificated Certificates in registered form substantially in the
form set forth in Exhibit A (the "Offshore Physical Certificates").  The
Offshore Physical Certificates and U.S. Physical Certificates are sometimes
collectively herein referred to as the "Physical Certificates".

                 (f)      The Exchange Certificates shall be issued in the form
of one or more global Certificates substantially in the form of Exhibit A to
the Related Pass Through Trust Agreement (each, a "Global Exchange
Certificate"), except that (i) the Private Placement Legend (hereinafter
defined) shall be omitted and (ii)  such Exchange Certificates shall contain
such appropriate insertions, omissions, substitutions and other variations from
the form set forth in Exhibit A to the Related Pass Through Trust Agreement
relating to the nature of the Exchange Certificates as the Responsible Officer
of the Trustee executing such Exchange Certificates on behalf of the Trust may
determine, as evidenced by such officer's execution on behalf of the Trust of
such Exchange Certificates.  Such Global Exchange Certificates shall be in
registered form and be registered in the name of DTC and deposited with the
Trustee, at its Corporate Trust Office, as custodian for DTC.  The aggregate
principal amount of any Global Exchange Certificate may from time to time be
increased or decreased by adjustments made on the records of the Trustee, as
custodian for DTC for such Global Exchange Certificate, which adjustments shall
be conclusive as to the aggregate principal amount of any such Global Exchange
Certificate.  Subject to clause (i) and (ii)  of the first sentence of this
Section 3.01(f), the terms hereof applicable to Restricted Global Certificates
and/or Global Certificates shall apply to the Global Exchange Certificates,
mutatis mutandis.

                 (g)      The definitive Certificates shall be in registered
form and shall be typed, printed, lithographed or engraved or produced by any
combination of these methods or may be produced in any other manner, all as
determined by the officers executing such Certificates, as evidenced by their
execution of such Certificates.

                 Section 3.02.  Restrictive Legends.  (a)  Subject to Section
3.06, unless and until (i) an Initial Certificate is sold under an effective
Registration Statement or (ii) an Initial Certificate is exchanged for an
Exchange Certificate pursuant to an effective Exchange Offer Registration
Statement, in each case as provided for in the Registration Rights Agreement,
<PAGE>   27
                                       21

each Global Certificate (other than the Permanent Offshore Global Certificate)
and each U.S. Physical Certificate shall bear the following legend (the
"Private Placement Legend") on the face thereof:

                 THIS CERTIFICATE HAS NOT BEEN REGISTERED UNDER THE U.S.
         SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND
         ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR
         TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY PERSONS EXCEPT AS SET FORTH
         IN THE FOLLOWING SENTENCE.  BY ITS ACQUISITION HEREOF, THE HOLDER (1)
         REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS
         DEFINED IN RULE 144A UNDER THE SECURITIES ACT), (B) IT IS AN
         INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)(1),
         (2), (3) OR (7) OF REGULATION D UNDER THE SECURITIES ACT) (AN
         "INSTITUTIONAL ACCREDITED INVESTOR") OR (C) IT IS NOT A U.S.  PERSON
         AND IS ACQUIRING THIS CERTIFICATE IN AN OFFSHORE TRANSACTION IN
         COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT; (2) AGREES THAT
         IT WILL NOT WITHIN TWO YEARS AFTER THE LATER OF THE ORIGINAL ISSUANCE
         OF THIS CERTIFICATE OR THE LAST DATE ON WHICH THIS CERTIFICATE WAS
         HELD BY ATLAS AIR, INC., THE TRUSTEE OR ANY AFFILIATE OF ANY OF SUCH
         PERSONS RESELL OR OTHERWISE TRANSFER THIS CERTIFICATE EXCEPT (A) TO A
         QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE
         SECURITIES ACT, (B) INSIDE THE UNITED STATES TO AN INSTITUTIONAL
         ACCREDITED INVESTOR ACQUIRING $100,000 OR MORE AGGREGATE PRINCIPAL
         AMOUNT OF  SUCH CERTIFICATE THAT, PRIOR TO SUCH TRANSFER, FURNISHES TO
         THE TRUSTEE A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND
         AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THIS
         CERTIFICATE (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM THE
         TRUSTEE), (C) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN
         COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT, (D) PURSUANT TO THE
         EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES
         ACT (IF AVAILABLE) OR (E) PURSUANT TO AN EFFECTIVE REGISTRATION
         STATEMENT UNDER THE SECURITIES ACT; AND (3) AGREES THAT IT WILL
         DELIVER TO EACH PERSON TO WHOM THIS CERTIFICATE IS TRANSFERRED A
         NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.  IN CONNECTION WITH
         ANY TRANSFER OF THIS CERTIFICATE WITHIN TWO YEARS AFTER THE LATER OF
         THE ORIGINAL ISSUANCE OF THIS CERTIFICATE OR THE LAST DATE ON WHICH
         THIS CERTIFICATE WAS HELD BY ATLAS AIR,
<PAGE>   28
                                       22

         INC., THE TRUSTEE OR ANY AFFILIATE OF ANY OF SUCH PERSONS THE HOLDER
         MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF
         RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO
         THE TRUSTEE.  AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION",
         "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM BY
         REGULATION S UNDER THE SECURITIES ACT.  THE PASS THROUGH TRUST
         AGREEMENT CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO
         REGISTER ANY TRANSFER OF THIS CERTIFICATE IN VIOLATION OF THE
         FOREGOING RESTRICTIONS.

                 (b)      Each Global Certificate shall also bear the following
legend on the face thereof:

         UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE
         OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO
         THE TRUSTEE OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR
         PAYMENT, AND ANY CERTIFICATE ISSUED IN EXCHANGE FOR THIS CERTIFICATE
         IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS
         REQUESTED BY AN AUTHORIZED  REPRESENTATIVE OF DTC (AND ANY PAYMENT
         HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED
         BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER
         USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL
         INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
         HEREIN.

         TRANSFERS OF THIS GLOBAL CERTIFICATE SHALL BE LIMITED TO TRANSFERS IN
         WHOLE, BUT NOT IN PART, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF
         OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL
         CERTIFICATE SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE
         RESTRICTIONS SET FORTH IN SECTIONS 3.05 AND 3.06 OF THE PASS THROUGH
         TRUST AGREEMENT REFERRED TO HEREIN.

                 Section 3.03.  Authentication of Certificates.  (a)
[Intentionally omitted]

                 (b)      No Certificate shall be entitled to any benefit under
this Agreement or be valid or obligatory for any purpose, unless there appears
on such Certificate a certificate of authentication substantially in the form
provided for herein executed by the Related Trustee or by the Trustee by the
manual signature of one of its authorized signatories, and
<PAGE>   29
                                       23

such certificate upon any Certificate shall be conclusive evidence, and the
only evidence, that such Certificate has been duly authenticated and delivered
hereunder.

                 Section 3.04.  Transfer and Exchange.  The Trustee shall cause
to be kept at the office or agency to be maintained by it in accordance with
the provisions of Section 7.12 of this Agreement a register (the "Register")
for the Certificates in which, subject to such reasonable regulations as it may
prescribe, the Trustee shall provide for the registration of the Certificates
and of transfers and exchanges of the Certificates as herein provided.  The
Trustee shall initially be the registrar (the "Registrar") for the purpose of
registering the Certificates and transfers and exchanges of the Certificates as
herein provided.  A Certificateholder may transfer a Certificate by written
application to the Registrar stating the name of the proposed transferee and
otherwise complying with the terms of this Agreement, including providing a
written certificate or other evidence of compliance with any restrictions on
transfer.  No such transfer shall be effected until, and such transferee shall
succeed to the rights of a Certificateholder only upon, final acceptance and
registration of the transfer by the Registrar in the Register.  Prior to the
registration of any transfer by a Certificateholder as provided herein, the
Trustee shall treat the person in whose name the Certificate is registered as
the owner thereof for all purposes, and the Trustee shall not be affected by
notice to the contrary.  Furthermore, the Depositary shall, by acceptance of a
Global Certificate, agree that transfers of beneficial interests in such Global
Certificate may be effected only through a book-entry system maintained by the
Depositary (or its agent), and that ownership of a beneficial interest in the
Certificate shall be required to be reflected in a book entry.  When
Certificates are presented to the Registrar with a request to register the
transfer or to exchange them for an equal face amount of Certificates of other
authorized denominations, the Registrar shall register the transfer or make the
exchange as requested if its requirements for such transactions are met.  To
permit registrations of transfers and exchanges in accordance with the terms,
conditions and restrictions hereof, the Trustee shall execute and authenticate
Certificates at the Registrar's request.  No service charge shall be made for
any registration of transfer or exchange of the Certificates, but the Trustee
may require payment by the transferor 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 charges payable upon
exchanges pursuant to Section 3.10 or 9.07).

                 Section 3.05.  Book-Entry Provisions for U.S. Global
Certificate and Offshore Global Certificates.  (a) Members of, or participants
in, the Depositary ("Agent Members") shall have no rights under this Agreement
with respect to any Global Certificate held on their behalf by the Depositary,
or the Trustee as its custodian, and the Depositary may be treated by the
Trustee and any agent of the Trustee as the absolute owner of such Global
Certificate for all purposes whatsoever.  Notwithstanding the foregoing,
nothing herein shall prevent the Trustee or any agent of the Trustee from
giving effect to any written certification, proxy or other authorization
furnished by the Depositary or shall impair, as between the Depositary
<PAGE>   30
                                       24

and its Agent Members, the operation of customary practices governing the
exercise of the rights of a holder of any Certificate.  Upon the issuance of
any Global Certificate, the Registrar or its duly appointed agent shall record
a nominee of the Depositary as the registered holder of such Global
Certificate.

                 (b)      Transfers of any Global Certificate shall be limited
to transfers of such Global Certificate or Offshore Global Certificate in
whole, but not in part, to nominees of the Depositary, its successor or such
successor's nominees.  Beneficial interests in the U.S. Global Certificate and
any Offshore Global Certificate may be transferred in accordance with the rules
and procedures of the Depositary and the provisions of Section 3.06.
Beneficial interests in the U.S. Global Certificate or an Offshore Global
Certificate shall be delivered to all beneficial owners in the form of U.S.
Physical Certificates or Offshore Physical Certificates, as the case may be, if
(i) the Depositary notifies the Trustee that it is unwilling or unable to
continue as Depositary for the U.S. Global Certificate or such Offshore Global
Certificate, as the case may be, and a successor depositary is not appointed by
the Trustee within 90 days of such notice or (ii) an Event of Default has
occurred and is continuing and the Registrar has received a request from the
Depositary to issue Physical Certificates.

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

                 (d)      In connection with the transfer of the entire U.S.
Global Certificate or an entire Offshore Global Certificate to the beneficial
owners thereof pursuant to paragraph (b) of this Section 3.05, such U.S. Global
Certificate or Offshore Global Certificate, as the case may be, shall be deemed
to be surrendered to the Trustee for cancellation, and the Trustee shall
execute, authenticate and deliver, to each beneficial owner identified by the
Depositary in exchange for its beneficial interest in such U.S. Global
Certificate or Offshore Global Certificate, as the case may be, an equal
aggregate principal amount of U.S. Physical Certificates or Offshore Physical
Certificates, as the case may be, of authorized denominations.

                 (e)      Any U.S. Physical Certificate delivered in exchange
for an interest in the U.S. Global Certificate pursuant to paragraph (b) of
this Section 3.05 shall, except as otherwise provided by paragraph (f) of
Section 3.06, bear the Private Placement Legend.

                 (f)      Any Offshore Physical Certificate delivered in
exchange for an interest in an Offshore Global Certificate pursuant to
paragraph (b) of this Section shall, except as
<PAGE>   31
                                       25

otherwise provided by paragraph (f) of Section 3.06, bear the applicable legend
regarding transfer restrictions set forth in Section 3.02(a).

                 (g)      The registered holder of the U.S. Global Certificate
or any Offshore Global Certificate 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
Agreement or the Certificates.

                 Section 3.06.  Special Transfer Provisions.  Unless and until
(i) an Initial Certificate is sold under an effective Registration Statement,
or (ii) an Initial Certificate is exchanged for an Exchange Certificate
pursuant to an effective Exchange Offer Registration Statement, in each case
pursuant to the Registration Rights Agreement, the following provisions shall
apply to such Initial Certificates:

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

                          (i)     The Registrar shall register the transfer of
                 any Certificate, whether or not such Certificate bears the
                 Private Placement Legend, if (x) the requested transfer is at
                 least three years after the later of the original issue date
                 of the Certificates and the last date on which such
                 Certificate was held by the Company or any affiliate of any
                 such persons or (y) the proposed transferee has delivered to
                 the Registrar a letter substantially in the form of Exhibit D
                 to the Related Pass Through Trust Agreement and the aggregate
                 principal amount of the Certificates being transferred is at
                 least $100,000.

                          (ii)    If the proposed transferor is an Agent Member
                 holding a beneficial interest in the U.S. Global
                 Certificate, 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 of the transfer and a decrease in
                 the principal amount of such U.S. Global Certificate in an
                 amount equal to the principal amount of the beneficial
                 interest in such U.S. Global Certificate to be transferred,
                 and the Company shall execute, and the Trustee shall
                 authenticate and deliver to the transferor or at its
                 direction, one or more U.S. Physical Certificates of like
                 tenor and amount.

                 (b)      Transfers to QIBs.  The following provisions shall
        apply with respect to the registration of any proposed transfer of an
        Initial Certificate to a QIB (excluding Non-U.S. Persons):

                                       26


                          (i)     If the Certificate to be transferred consists
                 of U.S. Physical Certificates or an interest in any Temporary
                 Offshore Global Certificate, 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
                 Initial Certificate stating, or has otherwise advised the
                 Trustee 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 Initial Certificate stating, or has otherwise
                 advised the Trustee and the Registrar in writing, that it is
                 purchasing the Initial Certificate for its own account or an
                 account with respect to which it exercises sole investment
                 discretion and that it, or the Person on whose behalf it is
                 acting with respect to 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 Trust and/or 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.

                          (ii)    Upon receipt by the Registrar of the
                 documents referred to in clause (i) above and instructions
                 given in accordance with the Depositary's and the Registrar's
                 procedures therefor, the Registrar shall reflect on its books
                 and records the date of such transfer and an increase in the
                 principal amount of the U.S. Global Certificate in an amount
                 equal to the principal amount of the U.S. Physical
                 Certificates or interests in the Temporary Offshore Global
                 Certificate, as the case may be, being transferred, and the
                 Trustee shall cancel such Physical Certificates or decrease
                 the amount of such Temporary Offshore Global Certificate so
                 transferred.

                 (c)      Transfers of Interests in the Permanent Offshore
        Global Certificate or Offshore Physical Certificates.  The Registrar
        shall register any transfer of interests in the Permanent Offshore
        Global Certificate or Offshore Physical Certificates without requiring
        any additional certification.

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

                          (i)     Prior to the Offshore Certificates Exchange
                 Date, the Registrar shall register any proposed transfer of an
                 Initial Certificate to a Non-U.S. Person upon receipt of a
                 certificate substantially in the form set forth as Exhibit C
                 to the Related Pass Through Trust Agreement from the proposed
                 transferor.
<PAGE>   33
                                       27

                          (ii)    On and after the Offshore Certificates
                 Exchange Date, the Registrar shall register any proposed
                 transfer to any Non-U.S. Person if the Certificate to be
                 transferred is a U.S. Physical Certificate or an interest in
                 the U.S. Global Certificate, upon receipt of a certificate
                 substantially in the form of Exhibit C from the proposed
                 transferor.  The Registrar shall promptly send a copy of such
                 certificate to the Company.

                          (iii)   Upon receipt by the Registrar of (x) the
                 documents, if any, required by paragraph (ii) 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 of such transfer and a decrease in
                 the principal amount of such U.S. Global Certificate in an
                 amount equal to the principal amount of the beneficial
                 interest in such U.S. Global Certificate to be transferred,
                 and (B) 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 Certificate in an amount equal to the
                 principal amount of the U.S. Physical Certificate or the U.S.
                 Global Certificate, as the case may be, to be transferred, and
                 the Trustee shall cancel the Physical Certificate, if any, so
                 transferred or decrease the amount of such U.S. Global
                 Certificate.

                 (e)      Private Placement Legend.  Upon the transfer,
        exchange or replacement of Certificates not bearing the Private
        Placement Legend, the Registrar shall deliver Certificates that do not
        bear the Private Placement Legend.  Upon the transfer, exchange or
        replacement of Certificates bearing the Private Placement Legend, the
        Registrar shall deliver only Certificates that bear the Private
        Placement Legend unless either (i) the circumstances contemplated by
        paragraph (a)(i)(x) or (e)(ii) of this Section 3.06 exist or (ii) there
        is delivered to the Registrar an Opinion of Counsel 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 Certificate
        bearing the Private Placement Legend, each Holder of such a Certificate
        acknowledges the restrictions on transfer of such Certificate set forth
        in this Agreement and agrees that it will transfer such Certificate only
        as provided in this Agreement.  The Registrar shall not register a
        transfer of any Certificate unless such transfer complies with the
        restrictions on transfer of such Certificate set forth in this
        Agreement.  In connection with any transfer of Certificates, each
        Certificateholder agrees by its acceptance of the Certificates to
        furnish the Registrar or the Trustee 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,
<PAGE>   34
                                       28

        the registration requirements of the Securities Act; provided that the
        Registrar shall not be required to determine the sufficiency of any such
        certifications, legal opinions or other information.

                 Until such time as no Certificates remain Outstanding, the
Registrar shall retain copies of all letters, notices and other written
communications received pursuant to Section 3.05 or this Section 3.06. The
Trustee, if not the Registrar at such time, 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 3.07.  Mutilated, Destroyed, Lost or Stolen
Certificates.  If (a) any mutilated Certificate is surrendered to the Registrar
or the Registrar receives evidence to its satisfaction of the destruction, loss
or theft of any Certificate and (b) there is delivered to the Registrar and the
Trustee such security, indemnity or bond, as may be required by them to save
each of them harmless, then, in the absence of notice to the Registrar or the
Trustee that such destroyed, lost or stolen Certificate has been acquired by a
bona fide purchaser, and provided that the requirements of Section 8-405 of the
Uniform Commercial Code in effect in any applicable jurisdiction are met, the
Trustee shall execute, authenticate and deliver, in exchange for or in lieu of
any such mutilated, destroyed, lost or stolen Certificate, a new Certificate or
Certificates, in authorized denominations and of like Fractional Undivided
Interest and bearing a number not contemporaneously outstanding.

                 In connection with the issuance of any new Certificate under
this Section 3.07, the Trustee may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Trustee
and the Registrar) connected therewith.

                 Any duplicate Certificate issued pursuant to this Section 3.07
shall constitute conclusive evidence of the appropriate Fractional Undivided
Interest in the Trust, as if originally issued, whether or not the lost, stolen
or destroyed Certificate shall be found at any time.

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

                 Section 3.08.  Persons Deemed Owners.  Prior to due
presentment of a Certificate for registration of transfer, the Trustee, the
Registrar and any Paying Agent may treat the Person in whose name any
Certificate is registered (as of the day of determination) as the owner of such
Certificate for the purpose of receiving distributions pursuant to Article
<PAGE>   35
                                       29

IV and for all other purposes whatsoever, and none of the Trustee, the
Registrar or any Paying Agent shall be affected by any notice to the contrary.

                 Section 3.09.  Cancellation.  All Certificates surrendered for
payment or transfer or exchange shall, if surrendered to the Trustee or any
agent of the Trustee other than the Registrar, be delivered to the Registrar
for cancellation and shall promptly be cancelled by it.  No Certificates shall
be authenticated in lieu of or in exchange for any Certificates cancelled as
provided in this Section, except as expressly permitted by this Agreement.  All
cancelled Certificates held by the Registrar shall be destroyed and a
certification of their destruction delivered to the Trustee.

                 Section 3.10.  Temporary Certificates.  Until definitive
Certificates are ready for delivery, the Trustee shall authenticate temporary
Certificates.  Temporary Certificates shall be substantially in the form of
definitive Certificates but may have insertions, substitutions, omissions and
other variations determined to be appropriate by the officers executing the
temporary Certificates, as evidenced by their execution of such temporary
Certificates.  If temporary Certificates are issued, the Trustee will cause
definitive Certificates to be prepared without unreasonable delay.  After the
preparation of definitive Certificates, the temporary Certificates shall be
exchangeable for definitive Certificates upon surrender of the temporary
Certificates at the office or agency of the Trustee designated for such purpose
pursuant to Section 7.12, without charge to the Certificateholder.  Upon
surrender for cancellation of any one or more temporary Certificates, the
Trustee shall execute, authenticate and deliver in exchange therefor a like
face amount of definitive Certificates of authorized denominations.  Until so
exchanged, the temporary Certificates shall be entitled to the same benefits
under this Agreement as definitive Certificates.

                 Section 3.11.  Limitation of Liability for Payments.  All
payments and distributions made to Certificateholders shall be made only from
the Trust Property and only to the extent that the Trustee shall have
sufficient income or proceeds from the Trust Property to make such payments in
accordance with the terms of Article IV of this Agreement.  Each
Certificateholder, by its acceptance of a Certificate, agrees that it will look
solely to the income and proceeds from the Trust Property for any payment or
distribution due to such Certificateholder pursuant to the terms of this
Agreement and that it will not have any recourse to the Company, the Trustee,
the Loan Trustees, the Liquidity Providers, the Owner Trustees or the Owner
Participants, except as otherwise expressly provided herein or in the
Intercreditor Agreement.

                 The Company is a party to this Agreement solely for purposes
of meeting the requirements of the Trust Indenture Act, and therefore shall not
have any right, obligation or liability hereunder (except as otherwise
expressly provided herein).

                               CERTIFICATEHOLDERS

                 Section 4.01.  Certificate Account and Special Payments
Account.  (a)  The Trustee shall establish and maintain on behalf of the
Certificateholders a Certificate Account as one or more non-interest-bearing
accounts.  The Trustee shall hold such Certificate Account in trust for the
benefit of the Certificateholders, and shall make or permit withdrawals
therefrom only as provided in this Agreement.  On each day when a Scheduled
Payment is made to the Trustee under the Intercreditor Agreement with respect
to the Certificates, the Trustee, upon receipt thereof, shall immediately
deposit the aggregate amount of such Scheduled Payment in such Certificate
Account.

                 (b)      The Trustee shall establish and maintain on behalf of
the Certificateholders a Special Payments Account as one or more accounts,
which shall be non-interest bearing except as provided in Section 4.04. The
Trustee shall hold the Special Payments Account in trust for the benefit of the
Certificateholders and shall make or permit withdrawals therefrom only as
provided in this Agreement.  On each day when one or more Special Payments are
made to the Trustee under the Intercreditor Agreement and upon payment of the
Special Redemption Premium to the Trustee under the Note Purchase Agreement
with respect to the Certificates, the Trustee, upon receipt thereof, shall
immediately deposit the aggregate amount of such Special Payments in such
Special Payments Account.

                 (c)      The Trustee shall present (or, if applicable, cause
the Subordination Agent to present) to the related Loan Trustee of each
Equipment Note such Equipment Note on the date of its stated final maturity or,
in the case of any Equipment Note which is to be redeemed in whole pursuant to
the related Indenture, on the applicable redemption date under such Indenture.

                 Section 4.02.  Distributions from Certificate Account and
Special Payments Account.  (a)  On each Regular Distribution Date with respect
to a series of Certificates or as soon thereafter as the Trustee has confirmed
receipt of the payment of all or any part of the Scheduled Payments due on the
Equipment Notes held (subject to the Intercreditor Agreement) in the related
Trust on such date, the Trustee shall distribute out of the applicable
Certificate Account the entire amount deposited therein pursuant to Section
4.01(a).  There shall be so distributed to each Certificateholder of record of
such series on the Record Date with respect to such Regular Distribution Date
(other than as provided in Section 11.01 concerning the final distribution) by
check mailed to such Certificateholder, at the address appearing in the
Register, such Certificateholder's pro rata share (based on the Fractional
Undivided Interest in the Trust held by such Certificateholder)
<PAGE>   37
                                       31

of the total amount in the applicable Certificate Account, except that, with
respect to Certificates registered on the Record Date in the name of a Clearing
Agency (or its nominee), such distribution shall be made by wire transfer in
immediately available funds to the account designated by such Clearing Agency
(or such nominee).

                 (b)      On each Special Distribution Date with respect to any
Special Payment with respect to the Certificates or as soon thereafter as the
Trustee has confirmed receipt of any Special Payments due on the Equipment
Notes held (subject to the Intercreditor Agreement) in the related Trust or
realized upon the sale of such Equipment Notes or receipt of the Special
Redemption Premium, the Trustee shall distribute out of the applicable Special
Payments Account the entire amount of such applicable Special Payment deposited
therein pursuant to Section 4.01(b).  There shall be so distributed to each
Certificateholder of record of such series on the Record Date with respect to
such Special Distribution Date (other than as provided in Section 11.01
concerning the final distribution) by check mailed to such Certificateholder,
at the address appearing in the Register, such Certificateholder's pro rata
share (based on the Fractional Undivided Interest in the related Trust held by
such Certificateholder) of the total amount in the applicable Special Payments
Account on account of such Special Payment, except that, with respect to
Certificates registered on the Record Date in the name of a Clearing Agency (or
its nominee), such distribution shall be made by wire transfer in immediately
available funds to the account designated by such Clearing Agency (or such
nominee).

                 (c)      The Trustee shall, at the expense of the Company,
cause notice of each Special Payment with respect to a series of Certificates
to be mailed to each Certificateholder at his address as it appears in the
Register.  In the event of redemption or purchase of Equipment Notes held in
the related Trust, such notice shall be mailed not less than 15 days prior to
the Special Distribution Date for the Special Payment resulting from such
redemption or purchase, which Special Distribution Date shall be the date of
such redemption or purchase.  In the event that any Special Redemption Premium
is to be paid by the Company to the Trustee under the Note Purchase Agreement,
such notice shall be mailed, together with the notice by the Escrow Paying
Agent under Section 2.06 of the Escrow Agreement, not less than 20 days prior
to the Special Distribution Date for such amount, which Special Distribution
Date shall be the Final Withdrawal Date.  In the case of any other Special
Payments, such notice shall be mailed as soon as practicable after the Trustee
has confirmed that it has received funds for such Special Payment, stating the
Special Distribution Date for such Special Payment which shall occur not less
than 15 days after the date of such notice and as soon as practicable
thereafter.  Notices mailed by the Trustee shall set forth:

                 (i)      the Special Distribution Date and the Record Date
         therefor (except as otherwise provided in Section 11.01);
<PAGE>   38
                                       32

                 (ii)     the amount of the Special Payment for each $1,000
         face amount Certificate and the amount thereof constituting principal,
         premium, if any, and interest;

                 (iii)    the reason for the Special Payment; and

                 (iv)     if the Special Distribution Date is the same date as
         a Regular Distribution Date for the Certificates, the total amount to
         be received on such date for each $1,000 face amount Certificate.

If the amount of (i) premium, if any, payable upon the redemption or purchase
of an Equipment Note or (ii) the Special Redemption Premium, if any, has not
been calculated at the time that the Trustee mails notice of a Special Payment,
it shall be sufficient if the notice sets forth the other amounts to be
distributed and states that any premium received will also be distributed.

                 If any redemption of the Equipment Notes held in any Trust is
cancelled, the Trustee, as soon as possible after learning thereof, shall cause
notice thereof to be mailed to each Certificateholder at its address as it
appears on the Register.

                 Section 4.03.  Statements to Certificateholders.  (a)  On each
Regular Distribution Date and Special Distribution Date, the Trustee will
include with each distribution of a Scheduled Payment or Special Payment, as
the case may be, to Certificateholders a statement setting forth the
information provided below (in the case of a Special Payment, including any
Special Redemption Premium, reflecting in part the information provided by the
Escrow Paying Agent under the Escrow Agreement).  Such statement shall set
forth (per $1,000 aggregate principal amount of Certificate as to (ii), (iii),
(iv) and (v) below) the following information:

                 (i)      the aggregate amount of funds distributed on such
         Distribution Date under the Agreement and under the Escrow Agreement,
         indicating the amount allocable to each source;

                 (ii)     the amount of such distribution under this Agreement
         allocable to principal and the amount allocable to premium (including
         the Special Redemption Premium), if any;

                 (iii)    the amount of such distribution under this Agreement
         allocable to interest;

                 (iv)     the amount of such distribution under the Escrow
         Agreement allocable to interest;
<PAGE>   39
                                       33


                 (v)      the amount of such distribution under the Escrow
         Agreement allocable to Deposits; and

                 (vi)     the Pool Balance and the Pool Factor.

                 With respect to the Certificates registered in the name of a
Clearing Agency or its nominee, on the Record Date prior to each Distribution
Date, the Trustee will request from the Clearing Agency a securities position
listing setting forth the names of all Clearing Agency Participants reflected
on the Clearing Agency's books as holding interests in the Certificates on such
Record Date.  On each Distribution Date, the Trustee will mail to each such
Clearing Agency Participant the statement described above and will make
available additional copies as requested by such Clearing Agency Participant
for forwarding to holders of interests in the Certificates.

                 (b)      Within a reasonable period of time after the end of
each calendar year but not later than the latest date permitted by law, the
Trustee shall furnish to each Person who at any time during such calendar year
was a Certificateholder of record a statement containing the sum of the amounts
determined pursuant to clauses (a)(i), (a)(ii), (a)(iii), (a)(iv) and (a)(v)
above with respect to the related Trust for such calendar year or, in the event
such Person was a Certificateholder of record during a portion of such calendar
year, for the applicable portion of such year, and such other items as are
readily available to the Trustee and which a Certificateholder shall reasonably
request as necessary for the purpose of such Certificateholder's preparation of
its federal income tax returns.  Such statement and such other items shall be
prepared on the basis of information supplied to the Trustee by the Clearing
Agency Participants and shall be delivered by the Trustee to such Clearing
Agency Participants to be available for forwarding by such Clearing Agency
Participants to the holders of interests in the Certificates in the manner
described in Section 4.03(a).

                 (c)      Promptly following (i) the Transfer Date, if there
has been any change in the information set forth in clauses (x), (y) and (z)
below from that set forth in page 65 of the Offering Memorandum, and (ii) any
early redemption or purchase of, or any default in the payment of principal or
interest in respect of, any of the Equipment Notes held in the Trust, or any
Final Withdrawal, the Trustee shall furnish to Certificateholders of record on
such date a statement setting forth (x) the expected Pool Balances for each
subsequent Regular Distribution Date following the Transfer Date, (y) the
related Pool Factors for such Regular Distribution Dates and (z) the expected
principal distribution schedule of the Equipment Notes, in the aggregate, held

         Company as an entirety shall execute and deliver to the Trustee
         applicable to the Certificates a duly authorized, valid, binding and
         enforceable agreement in form and substance reasonably satisfactory to
         the Trustee containing an assumption by such successor corporation or
         Person of the due and punctual performance and observance of each

         than all, of the Certificates and the Class A Certificates pro rata
         based on the Fractional Undivided Interest in the Class C Trust held

         notify the purchasing Class C Certificateholder of such other Class C
         Certificateholder's desire to participate in such a purchase, then
         such other Class C Certificateholder shall lose its right to purchase
         the Certificates pursuant to this Section 6.01(b); and

                 (ii)     each Class D Certificateholder shall have the right

         the Class D Trust held by each such Class D Certificateholder and (B)
         if prior to the end of such ten-day period any other Class D
         Certificateholder fails to notify the purchasing Class D
         Certificateholder of such other Class D Certificateholder's desire to
         participate in such a purchase, then such other Class D
         Certificateholder shall lose its right to purchase the Certificates
         pursuant to this Section 6.01(b).

                 The purchase price with respect to the Certificates shall be
equal to the Pool Balance of the Certificates, together with accrued and unpaid
interest thereon to the date of such purchase, without premium, but including
any other amounts then due and payable to the Certificateholders under this
Agreement, the Intercreditor Agreement, the Escrow Agreement or any Note
Document or on or in respect of the Certificates; provided, however, that (i)
if such purchase occurs after the record date specified in Section 2.03(b) of
the
<PAGE>   43
                                       37

Escrow Agreement relating to the distribution of unused Deposits and accrued
and unpaid interest thereunder, such purchase price shall be reduced by the
aggregate amount of unused Deposits and interest to be distributed under the
Escrow Agreement (which deducted amounts shall remain distributable to, and may
be retained by, the Certificateholder as of such Record Date) and (ii) if such
purchase occurs after a Record Date, such purchase price shall be reduced by
the amount to be distributed hereunder on the related Distribution Date (which

purchaser(s) is purchasing, pursuant to the terms of this Agreement and the
Other Agreements, the Certificates, the Class A Certificates and the Class C
Certificates which are senior to the securities held by such purchaser(s).
Each payment of the purchase price of the Certificates referred to in the first

Trustee and each such purchase shall be subject to the terms of this Section
6.01(b).  Each Certificateholder agrees by its acceptance of its Certificate
that it will, subject to Section 3.04 of this Agreement, upon payment from such
Class C Certificateholder(s) or Class D Certificateholder(s), as the case may
be, of the purchase price set forth in the first sentence of this paragraph,
forthwith sell, assign, transfer and convey to the purchaser(s) thereof
(without recourse, representation or warranty of any kind except for its own
acts), all of the right, title, interest and obligation of such
Certificateholder in this Agreement, the Escrow Agreement, the Deposit

Documents and all Certificates and Escrow Receipts held by such
Certificateholder (excluding all right, title and interest under any of the
foregoing to the extent such right, title or interest is with respect to an
obligation not then due and payable as respects any action or inaction or state
of affairs occurring prior to such sale) and the purchaser shall assume all of
such Certificateholder's obligations under this Agreement, the Escrow
Agreement, the Deposit Agreement, the Intercreditor Agreement, the Liquidity
Facilities, the Note Documents and all such Certificates and Escrow Receipts.
The Certificates will be deemed to be purchased on the date payment of the
purchase price is made notwithstanding the failure of the Certificateholders to
deliver any Certificates and, upon such a purchase, (i) the only rights of the
Certificateholders will be to deliver the Certificates to the purchaser(s) and
receive the purchase price for such Certificates and (ii) if the purchaser(s)
shall so request, such Certificateholder will comply with all the provisions of
Section 3.04 of this Agreement to enable new Certificates to be issued to the
purchaser in such denominations as it shall request.  All charges and expenses
in connection with the issuance of any such new Certificates shall be borne by
the purchaser thereof.

sale of all or any part of the Equipment Notes held in the Trust made either
under the power of sale given under this Agreement or otherwise for the
enforcement of this Agreement, the following shall be applicable:

         other capacity or any other Person may bid for and purchase any of the

         of sale, may hold, retain, possess and dispose of such Equipment Notes
         in their own absolute right without further accountability.

                 (b)      Receipt of Trustee Shall Discharge Purchaser.  The
         receipt of the Trustee making such sale shall be a sufficient
         discharge to any purchaser for his purchase money, and, after paying
         such purchase money and receiving such receipt, such purchaser or its
         personal representative or assigns shall not be obliged to see to the
         application of such purchase money, or be in any way answerable for
         any loss, misapplication or nonapplication thereof.

                 (c)      Application of Moneys Received upon Sale.  Any moneys
         collected by the Trustee upon any sale made either under the power of
         sale given by this Agreement or otherwise for the enforcement of this
         Agreement shall be applied as provided in Section 4.02.

                 Section 6.03.  Judicial Proceedings Instituted by Trustee;
Trustee May Bring Suit.  If there shall be a failure to make payment of the
principal of, premium, if any, or interest on any Equipment Note held in the
Trust, or if there shall be any failure to pay Rent (as defined in the relevant
Lease) under any Lease when due and payable, then the Trustee, in, its own name
and as trustee of an express trust, as holder of such Equipment Notes, to the
extent permitted by and in accordance with the terms of any related
Intercreditor Agreement and any related Note Documents (subject to rights of
the applicable Owner Trustee or Owner Participant to cure any such failure to
pay principal of, premium, if any, or interest on any Equipment Note or to pay
Rent under any Lease in accordance with the applicable Indenture), shall be
entitled and empowered to institute any suits, actions or proceedings at law,
in equity or otherwise, for the collection of the sums so due and unpaid on
such Equipment Notes or under such Lease and may prosecute any such claim or
proceeding to judgment or final decree with respect to the whole amount of any
such sums so due and unpaid.

                 Section 6.04.  Control by Certificateholders.  Subject to
Section 6.03 and the Intercreditor Agreement, the Certificateholders holding
Certificates evidencing Fractional Undivided Interests aggregating not less
than a majority in interest in the related Trust shall have the right to direct
the time, method and place of conducting any proceeding for any

                                       39

remedy available to the Trustee with respect to the Trust or pursuant to the
terms of the Intercreditor Agreement, or exercising any trust or power
conferred on the Trustee under this Agreement or the Intercreditor Agreement,
including any right of the Trustee as Controlling Party under the Intercreditor
Agreement or as holder of the Equipment Notes held in the related Trust;
provided, however, that

                 (a)      such Direction shall not in the opinion of the
         Trustee be in conflict with any rule of law or with this Agreement and
         would not involve the Trustee in personal liability or expense,

                 (b)      the Trustee shall not determine that the action so
         directed would be unjustly prejudicial to the Certificateholders not
         taking part in such Direction, and

                 (c)      the Trustee may take any other action deemed proper
         by the Trustee which is not inconsistent with such Direction.

                 Section 6.05.  Waiver of Past Defaults.  Subject to any
related Intercreditor Agreement, the Certificateholders holding Certificates of
a series evidencing Fractional Undivided Interests aggregating not less than a
majority in interest in the Trust (i) may on behalf of all of the
Certificateholders waive any past Event of Default hereunder and its
consequences or (ii) if the Trustee is the Controlling Party, may direct the
Trustee to instruct the applicable Loan Trustee to waive any past Indenture
Event of Default under any related Indenture and its consequences, and thereby
annul any Direction given by such Certificateholders or the Trustee to such
Loan Trustee with respect thereto, except a default:

                 (a)      in the deposit of any Scheduled Payment or Special
         Payment under Section 4.01 or in the distribution of any payment under
         Section 4.02 on the Certificates, or

                 (b)      in the payment of the principal of (premium, if any)
         or interest on the Equipment Notes held in the Trust, or

                 (c)      in respect of a covenant or provision hereof which
         under Article IX hereof cannot be modified or amended without the
         consent of each Certificateholder holding an Outstanding Certificate
         of a series affected thereby.

Upon any such waiver, such default shall cease to exist with respect to the
Certificates and any Event of Default arising therefrom shall be deemed to have
been cured for every purpose and any direction given by the Trustee on behalf
of the Certificateholders to the relevant Loan Trustee shall be annulled with
respect thereto; but no such waiver shall extend to any subsequent or other
default or Event of Default or impair any right consequent thereon.
<PAGE>   46
                                       40

Upon any such waiver, the Trustee shall vote the Equipment Notes issued under
the relevant Indenture to waive the corresponding Indenture Event of Default.

                 Section 6.06.  Right of Certificateholders to Receive Payments
Not to Be Impaired.  Anything in this Agreement to the contrary
notwithstanding, including, without limitation, Section 6.07 hereof, but

the applicable Certificates when due, or to institute suit for the enforcement

Special Distribution Date, shall not be impaired or affected without the
consent of such Certificateholder.

                 Section 6.07.  Certificateholders May Not Bring Suit Except
Under Certain Conditions.  A Certificateholder shall not have the right to
institute any suit, action or proceeding at law or in equity or otherwise with
respect to this Agreement, for the appointment of a receiver or for the
enforcement of any other remedy under this Agreement, unless:

                 (a)      such Certificateholder previously shall have given
         written notice to the Trustee of a continuing Event of Default;

                 (b)      Certificateholders holding Certificates evidencing
         Fractional Undivided Interests aggregating not less than 25% of the
         related Trust shall have requested the Trustee in writing to institute
         such action, suit or proceeding and shall have offered to the Trustee
         indemnity as provided in Section 7.03(e);

                 (c)      the Trustee shall have refused or neglected to
         institute any such action, suit or proceeding for 60 days after
         receipt of such notice, request and offer of indemnity; and

under the related Trust Supplement or under the Certificates to (i) surrender,

of the Trust, or the lien of any related Indenture on any property subject
thereto, or the rights of the Certificateholders or the holders of the
Equipment Notes, (ii) obtain or seek to obtain priority over or preference with
respect to any other such Certificateholder or (iii) enforce any right under
this Agreement, except in the
<PAGE>   47
                                       41

manner herein provided and for the equal, ratable and common benefit of all the
Certificateholders subject to the provisions of this Agreement.

                 Section 6.08.  Remedies Cumulative.  Every remedy given
hereunder to the Trustee or to any of the Certificateholders shall not be
exclusive of any other remedy or remedies, and every such remedy shall be
cumulative and in addition to every other remedy given hereunder or now or
hereafter given by statute, law, equity or otherwise.

                 Section 6.09.  Undertaking for Costs.  In any suit for the
enforcement of any right or remedy under this Agreement, or in any suit against
the Trustee for any action taken, suffered or omitted by it as Trustee, a court
may require any party litigant in such suit to file an undertaking to pay the
costs of such suit, and may assess costs against any such party litigant, in
the manner and to the extent provided in the Trust Indenture Act; provided,
however, that neither this Section 6.09 nor the Trust Indenture Act shall be
deemed to authorize any court to require such an undertaking or to make such an
assessment in any suit instituted by the Company.

                                  THE TRUSTEE

                 Section 7.01.  Certain Duties and Responsibilities.  (a)
Except during the continuance of an Event of Default in respect of a Trust, the
Trustee undertakes to perform such duties in respect of the Trust as are
specifically set forth in this Agreement, and no implied covenants or
obligations shall be read into this Agreement against the Trustee.

                 (b)      In case an Event of Default in respect of a Trust has
occurred and is continuing, the Trustee shall exercise such of the rights and
powers vested in it by this Agreement in respect of the Trust, and use the same
degree of care and skill in their exercise, as a prudent man would exercise or
use under the circumstances in the conduct of his own affairs.

                 (c)      No provision of this Agreement 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

                 (i)      this Subsection shall not be construed to limit the
         effect of Subsection (a) of this Section 7.01; and
<PAGE>   48

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

                 (d)      Whether or not herein expressly so provided, every
provision of this Agreement relating to the conduct or affecting the liability
of or affording protection to the Trustee shall be subject to the provisions of
this Section 7.01.

                 Section 7.02.  Notice of Defaults.  As promptly as practicable
after, and in any event within 90 days after, the occurrence of any default (as
such term is defined below) hereunder known to the Trustee, the Trustee shall
transmit by mail to the Company, any Owner Trustees, the Owner Participants,
the Loan Trustees and the Certificateholders holding Certificates in accordance
with Section 313(c) of the Trust Indenture Act, notice of such default
hereunder known to the Trustee, unless such default shall have been cured or
waived; provided, however, that, except in the case of a default in the payment
of the principal, premium, if any, or interest on any Equipment 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 shall determine that
the withholding of such notice is in the interests of the Certificateholders.
For the purpose of this Section 7.02 in respect of any Trust, the term
"default" means any event that is, or after notice or lapse of time or both
would become, an Event of Default in respect of that Trust.

                 Section 7.03.  Certain Rights of Trustee.  Subject to the
provisions of Section 315 of the Trust Indenture Act:

                 (a)      the Trustee may rely and shall be protected in acting
         or refraining from acting in reliance upon any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture or other paper or document
         believed by it to be genuine and to have been signed or presented by
         the proper party or parties;

                 (b)      any request or direction of the Company mentioned
         herein shall be sufficiently evidenced by a Request;

                 (c)      whenever in the administration of this Agreement or
         the Intercreditor Agreement, 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 Officer's Certificate of the Company, any Owner
         Trustee or any Loan Trustee;
<PAGE>   49
                                       43

                 (d)      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;

                 (e)      the Trustee shall be under no obligation to exercise
         any of the rights or powers vested in it by this Agreement or the
         Intercreditor Agreement at the Direction of any of the
         Certificateholders pursuant to this Agreement or the Intercreditor
         Agreement, unless the Certificateholders shall have offered to the
         Trustee reasonable security or indemnity against the cost, expenses
         and liabilities which might be incurred by it in compliance with such
         Direction;

                 (f)      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 or other paper or document;

                 (g)      the Trustee may execute any of the trusts or powers
         under this Agreement or the Intercreditor Agreement or perform any
         duties under this Agreement or the Intercreditor Agreement 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 under this Agreement
         or the Intercreditor Agreement;

                 (h)      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 Certificateholders holding Certificates
         evidencing Fractional Undivided Interests aggregating not less than a
         majority in interest in the Trust relating to the time, method and
         place of conducting any proceeding for any remedy available to the
         Trustee, or exercising any trust or power conferred upon the Trustee,
         under this Agreement or the Intercreditor Agreement; and

                 (i)      the Trustee shall not be required to expend or risk
         its own funds in the performance of any of its duties under this
         Agreement, 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 is not reasonably
         assured to it.

                 Section 7.04.  Not Responsible for Recitals or Issuance of
Certificates.  The recitals contained herein and in the Certificates, except
the certificates of authentication, shall not be taken as the statements of the
Trustee, and the Trustee assumes no responsibility for their correctness.

Intercreditor Agreement,
<PAGE>   50
                                       44

the Deposit Agreement, the Escrow Agreement, the Certificates, or any Note
Documents, except that the Trustee hereby represents and warrants that this
Agreement has been, and the Registration Rights Agreement, each Certificate,
the Note Purchase Agreement, the Escrow Agreement and the Intercreditor
Agreement will be, executed and delivered by one of its officers who is duly
authorized to execute and deliver such document on its behalf.

                 Section 7.05.  May Hold Certificates.  The Trustee, any Paying
Agent, Registrar or any of their Affiliates or any other agent, in their
respective individual or any other capacity, may become the owner or pledgee of
Certificates and, subject to Sections 310(b) and 311 of the Trust Indenture
Act, if applicable, may otherwise deal with the Company, any Owner Trustees or
the Loan Trustees with the same rights it would have if it were not Trustee,
Paying Agent, Registrar or such other agent.

                 Section 7.06.  Money Held in Trust.  Money held by the Trustee
or the Paying Agent in trust under this Agreement need not be segregated from

                 Section 7.07.  Compensation and Reimbursement.  The Company
agrees:

                 (a)      to pay, or cause to be paid, to the Trustee from time
         to time  reasonable compensation for all services rendered by it
         hereunder (which compensation shall not be limited by any provision of
         law in regard to the compensation of a trustee of an express trust);
         and

                 (b)      to reimburse, or cause to be reimbursed, the Trustee
         upon its request for all reasonable out- of-pocket expenses,
         disbursements and advances incurred or made by the Trustee in
         accordance with any provision of this Agreement or the Intercreditor
         Agreement (including the reasonable compensation and the expenses and
         disbursements of its agents and counsel), except any such expense,
         disbursement or advance as may be attributable to its negligence,
         willful misconduct or bad faith or as may be incurred due to the
         Trustee's breach of its representations and warranties set forth in
         Section 7.15; and

                 (c)      to indemnify the Trustee with respect to the
         Certificates, pursuant to Section 8.1 of the Owned Aircraft
         Participation Agreements and Section 9.1 of the Leased Aircraft
         Participation Agreements, as the case may be.

                 The Trustee shall be entitled to reimbursement from, and shall
have a lien prior to the Certificates upon, all property and funds held or
collected by the Trustee in its capacity as Trustee for any tax incurred
without negligence, bad faith or willful misconduct, on its part, arising out
of or in connection with the acceptance or administration of the Trust
<PAGE>   51
                                       45

(other than any tax attributable to the Trustee's compensation for serving as
such), including any costs and expenses incurred in contesting the imposition
of any such tax.  The Trustee shall notify the Company of any claim for any tax
for which it may seek reimbursement.  If the Trustee reimburses itself from the
Trust Property of such Trust for any such tax, it will mail a brief report
within 30 days setting forth the amount of such tax and the circumstances
thereof to all Certificateholders as their names and addresses appear in the
Register.

                 Section 7.08.  Corporate Trustee Required; Eligibility.  The
Trust shall at all times have a Trustee which shall be eligible to act as a
trustee under Section 310(a) of the Trust Indenture Act and shall have a
combined capital and surplus of at least $75,000,000 (or a combined capital and
surplus in excess of $5,000,000 and the obligations of which, whether now in
existence or hereafter incurred, are fully and unconditionally guaranteed by a
corporation organized and doing business under the laws of the United States,
any state or territory thereof or of the District of Columbia and having a
combined capital and surplus of at least $75,000,000).  If such corporation
publishes reports of conditions at least annually, pursuant to law or to the
requirements of federal, state, territorial or District of Columbia supervising
or examining authority, then for the purposes of this Section 7.08 the combined
capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of conditions so
published.

                 In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 7.08 to act as Trustee of the
Trust, the Trustee shall resign immediately as Trustee of the Trust in the
manner and with the effect specified in Section 7.09.

                 Section 7.09.  Resignation and Removal; Appointment of
Successor.  (a)  No resignation or removal of the Trustee and no appointment of
a successor Trustee of the Trust pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee under
Section 7.10.

                 (b)      The Trustee may resign at any time as Trustee of the
Trust by giving prior written notice thereof to the Company, the Authorized
Agents, the Owner Trustees and the Loan Trustees.  If an instrument of
acceptance by a successor Trustee shall not have been delivered to the Company,
the Owner Trustees and the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

                 (c)      The Trustee may be removed at any time by Direction
of the Certificateholders holding Certificates evidencing Fractional Undivided
Interests aggregating not less than a majority in interest in such Trust
delivered to the Trustee and to the Company, the Owner Trustees and the Loan
Trustees.
<PAGE>   52
                                       46

                 (d)      If at any time in respect of the Trust:

                 (i)      the Trustee shall fail to comply with Section 310 of
         the Trust Indenture Act, if applicable, after written request therefor
         by the Company or by any Certificateholder who has been a bona fide
         Certificateholder for at least six months; or

                 (ii)     the Trustee shall cease to be eligible under Section
         7.08 and shall fail to resign after written request therefor by the
         Company or by any such Certificateholder; or

                 (iii)    the Trustee shall become incapable of acting or shall
         be adjudged a bankrupt or insolvent, or a receiver of the Trustee or
         of its property shall be appointed or any public officer shall take
         charge or control of the Trustee or of its property or affairs for the
         purpose of rehabilitation, conservation or liquidation;

then, in any case, (i) the Company may remove the Trustee or (ii) any
Certificateholder who has been a bona fide Certificateholder for at least six
months may, on behalf of itself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee of the Trust.

                 (e)      If a Responsible Officer of the Trustee shall obtain
actual knowledge of an Avoidable Tax (as defined below) in respect of any Trust
which has been or is likely to be asserted, the Trustee shall promptly notify
the Company and shall, within 30 days of such notification, resign as Trustee
of such Trust hereunder unless within such 30-day period the Trustee shall have
received notice that the Company has agreed to pay such tax.  The Company shall
promptly appoint a successor Trustee of such Trust in a jurisdiction where
there are no Avoidable Taxes.  As used herein, an "Avoidable Tax" in respect of
such Trust means a state or local tax:  (i) upon (w) such Trust, (x) such Trust
Property, (y) Certificateholders of the Trust or (z) the Trustee for which the
Trustee is entitled to seek reimbursement from the Trust Property of such
Trust, and (ii) which would be avoided if the Trustee were located in another
state, or jurisdiction within a state, within the United States of America.  A
tax shall not be an Avoidable Tax in respect of any Trust if the Company or any
Owner Trustee shall agree to pay, and shall pay, such tax.

                 (f)      If the Trustee shall resign, be removed or become
incapable of acting as Trustee of the Trust or if a vacancy shall occur in the
office of the Trustee of the Trust for any cause, the Company shall promptly
appoint a successor Trustee.  If, within one year after such resignation,
removal or incapability, or other occurrence of such vacancy, a successor
Trustee shall be appointed by Direction of the Certificateholders holding
Certificates evidencing Fractional Undivided Interests aggregating not less
than a majority in interest in such Trust delivered to the Company, the Owner
Trustees, the Loan Trustee and
<PAGE>   53
                                       47

the retiring Trustee, then the successor Trustee so appointed shall, with the
approval of the Company of such appointment, which approval shall not be
unreasonably withheld, forthwith upon its acceptance of such appointment,
become the successor Trustee and supersede the successor Trustee appointed as
provided above.  If no successor Trustee shall have been so appointed as
provided above and accepted appointment in the manner hereinafter provided, the
resigning Trustee or any Certificateholder who has been a bona fide
Certificateholder of the related series for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee.

                 (g)      The successor Trustee shall give notice of the
resignation and removal of the Trustee and appointment of the successor Trustee
by mailing written notice of such event by first-class mail, postage prepaid,
to the Certificateholders as their names and addresses appear in the Register.
Each notice shall include the name of such successor Trustee and the address of
its Corporate Trust Office.

                 Section 7.10.  Acceptance of Appointment by Successor.  Every
successor Trustee appointed hereunder shall execute and deliver to the Company
and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on request of the Company or the successor
Trustee, such retiring Trustee shall execute and deliver an instrument
transferring to such successor Trustee all such rights, powers and trusts of
the retiring Trustee and shall duly assign, transfer and deliver to such
successor Trustee all Trust Property held by such retiring Trustee, subject
nevertheless to its lien, if any, provided for in Section 7.07.  Upon request
of any such successor Trustee, the Company, the retiring Trustee and such
successor Trustee shall execute and deliver any and all instruments containing
such provisions as shall be necessary or desirable to transfer and confirm to,
and for more fully and certainly vesting in, such successor Trustee all such
rights, powers and trusts.

                 No institution shall accept its appointment as a Trustee
hereunder unless at the time of such acceptance such institution shall be
qualified and eligible under this Article VII.

                 Section 7.11.  Merger, Conversion, Consolidation or Succession
to Business.  Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder;
provided, however, that such corporation shall be otherwise qualified and
eligible under this Article VII, without the execution or filing of any paper
or any further act on the part of any of the parties hereto.  In case any
Certificates shall have been executed or authenticated, but
<PAGE>   54
                                       48

not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
execution or authentication and deliver the Certificates so executed or
authenticated with the same effect as if such successor Trustee had itself
executed or authenticated such Certificates.

                 Section 7.12.  Maintenance of Agencies.  (a)  With respect to
each series of Certificates, there shall at all times be maintained an office
or agency in the location set forth in Section 12.04 where Certificates may be
presented or surrendered for registration of transfer or for exchange, and for
payment thereof, and where notices and demands, to or upon the Trustee in
respect of such Certificates or this Agreement may be served; provided,
however, that, if it shall be necessary that the Trustee maintain an office or
agency in another location with respect to the Certificates (e.g., the
Certificates shall be represented by Definitive Certificates and shall be
listed on a national securities exchange), the Trustee will make all reasonable
efforts to establish such an office or agency.  Written notice of the location
of each such other office or agency and of any change of location thereof shall
be given by the Trustee to the Company, any Owner Trustees, the Loan Trustees
(in the case of any Owner Trustee or Loan Trustee, at its address specified in
the Note Documents or such other address as may be notified to the Trustee) and
the Certificateholders.  In the event that no such office or agency shall be
maintained or no such notice of location or of change of location shall be
given, presentations and demands may be made and notices may be served at the
Corporate Trust Office of the Trustee.

                 (b)      There shall at all times be a Registrar and a Paying
Agent hereunder with respect to the Certificates.  Each such Authorized Agent
shall be a bank or trust company, shall be a corporation organized and doing
business under the laws of the United States or any state, with a combined
capital and surplus of at least $75,000,000, or a corporation having a combined
capital and surplus in excess of $5,000,000, the obligations of which are
guaranteed by a corporation organized and doing business under the laws of the
United States or any state, with a combined capital and surplus of at least
$75,000,000, and shall be authorized under such laws to exercise corporate
trust powers, subject to supervision by federal or state authorities.  The
Trustee shall initially be the Paying Agent and, as provided in Section 3.04,
Registrar hereunder with respect to the Certificates.  Each Registrar shall
furnish to the Trustee, at stated intervals of not more than six months, and at
such other times as the Trustee may request in writing, a copy of the Register
maintained by such Registrar.

                 (c)      Any corporation into which any Authorized Agent may
be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, consolidation or conversion to which any Authorized
Agent shall be a party, or any corporation succeeding to the corporate trust
business of any Authorized Agent, shall be the successor of such Authorized
Agent, if such successor corporation is otherwise eligible under
<PAGE>   55
                                       49

this Section 7.12, without the execution or filing of any paper or any further
act on the part of the parties hereto or such Authorized Agent or such
successor corporation.

                 (d)      Any Authorized Agent may at any time resign by giving
written notice of resignation to the Trustee, the Company, any Owner Trustees
and the Loan Trustees.  The Company may, and at the request of the Trustee
shall, at any time terminate the agency of any Authorized Agent by giving
written notice of termination to such Authorized Agent and to the Trustee.
Upon the resignation or termination of an Authorized Agent or in case at any
time any such Authorized Agent shall cease to be eligible under this Section
7.12 (when, in either case, no other Authorized Agent performing the functions
of such Authorized Agent shall have been appointed), the Company shall promptly
appoint one or more qualified successor Authorized Agents, reasonably
satisfactory to the Trustee, to perform the functions of the Authorized Agent
which has resigned or whose agency has been terminated or who shall have ceased
to be eligible under this Section 7.12.  The Company shall give written notice
of any such appointment made by it to the Trustee, any Owner Trustees and the
Loan Trustees; and in each case the Trustee shall mail notice of such
appointment to all Certificateholders as their names and addresses appear on
the Register for such series.

                 (e)      The Company agrees to pay, or cause to be paid, from
time to time to each Authorized Agent reasonable compensation for its services
and to reimburse it for its reasonable expenses.

                 Section 7.13.  Money for Certificate Payments to Be Held in
Trust.  All moneys deposited with any Paying Agent for the purpose of any
payment on Certificates shall be deposited and held in trust for the benefit of
the Certificateholders entitled to such payment, subject to the provisions of
this Section 7.13. Moneys so deposited and held in trust shall constitute a
separate trust fund for the benefit of the Certificateholders with respect to
which such money was deposited.

                 The Trustee may at any time, for the purpose of obtaining the
satisfaction and discharge of this Agreement or for any other purpose, direct
any Paying Agent to pay to the Trustee all sums held in trust by such Paying
Agent, such sums to be held by the Trustee upon the same trusts as those upon
which such sums were held by such Paying Agent; and, upon such payment by any
Paying Agent to the Trustee, such Paying Agent shall be released from all
further liability with respect to such money.

                 Section 7.14.  Registration of Equipment Notes in Trustee's
Name.  Subject to the provisions of any Intercreditor Agreement, the Trustee
agrees that all Equipment Notes to be purchased by any Trust and Permitted
Investments, if any, shall be issued in the name of the Trustee as trustee for
the applicable Trust or its nominee and held by the Trustee in trust for the
benefit of the Certificateholders, or, if not so held, the Trustee or its
nominee shall be reflected as the owner of such Equipment Notes or Permitted
Investments, as the case may be, in the register of the issuer of such
Equipment Notes or Permitted Investments, as the case may be.

                 Section 7.15.  Representations and Warranties of Trustee.  The
Trustee hereby represents and warrants, on the Transfer Date, that:

         mortgage, indenture, contract, agreement or other undertaking to which
         it is a party, which violation, default or lien could reasonably be

         transactions contemplated herein or therein;

         any other action in respect of, any governmental authority or agency
         of the United States or the state of the United States where it is
         located regulating the banking and corporate trust activities of the
         Trustee; and
<PAGE>   57
                                       51

                 (e)      The Assignment and Assumption Agreement has been duly
         executed and delivered by the Trustee and this Agreement, the

         have been, or will be, as applicable, duly executed and delivered by
         the Trustee and constitute, or will constitute, as applicable, the
         legal, valid and binding agreements of the Trustee, enforceable
         against it in accordance with their respective terms; provided,
         however, that enforceability may be limited by (i) applicable
         bankruptcy, insolvency, reorganization, moratorium or similar laws
         affecting the rights of creditors generally and (ii) general
         principles of equity.

                 Section 7.16.  Withholding Taxes; Information Reporting.  As
to the Certificates, the Trustee, as trustee of the related grantor trust
created by this Agreement, shall exclude and withhold from each distribution of
principal, premium, if any, and interest and other amounts due under this
Agreement or under the Certificates any and all withholding taxes applicable
thereto as required by law.  The Trustee agrees to act as such withholding
agent and, in connection therewith, whenever any present or future taxes or
similar charges are required to be withheld with respect to any amounts payable
in respect of the Certificates, to withhold such amounts and timely pay the
same to the appropriate authority in the name of and on behalf of the
Certificateholders, that it will file any necessary withholding tax returns or
statements when due, and that, as promptly as possible after the payment
thereof, it will deliver to each such Certificateholder appropriate
documentation showing the payment thereof, together with such additional
documentary evidence as such Certificateholders may reasonably request from
time to time.  The Trustee agrees to file any other information reports as it
may be required to file under United States law.

                 Section 7.17.  Trustee's Liens.  The Trustee in its individual

Agreement, at its own cost and expense promptly take any action as may be

charge, encumbrance, security interest or claim ("Trustee's Liens") on or with
respect to the Trust Property of such Trust which is attributable to the

         such extent as shall be necessary to continue the qualification of
         this Agreement, the Intercreditor Agreement or any Liquidity Facility
         (including any supplemental agreement) under the Trust Indenture Act
         or under any similar Federal statute hereafter enacted, and to add to
         this Agreement, the Intercreditor Agreement or any Liquidity Facility
         such other provisions as may be expressly permitted by the Trust
         Indenture Act, excluding, however, the provisions referred to in

         Trustee and to add to or change any of the provisions of this

         provided, however, that such amendments or modifications shall apply

the status of any Trust as a grantor trust under Subpart E, Part I of
Subchapter J of Chapter 1 of Subtitle A of the Internal Revenue Code of 1986,
as amended, for U.S. federal income tax purposes.

                 Section 9.02.  Supplemental Agreements with Consent of
Certificateholders.  With respect to the Trust and the Certificates, with the
consent of the Certificateholders (including consents obtained in connection
with a tender offer or exchange offer for the Certificates) evidencing

in such Trust, by Direction of said Certificateholders delivered to the Company
and the Trustee, the Company may (with the consent of the Owner Trustees, if
any, relating to the Certificates, which consent shall not be unreasonably
withheld), but shall not be obligated to, and the Trustee (subject to Section
9.03) shall, enter into an agreement or agreements supplemental hereto for the
purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Agreement, the Intercreditor Agreement, the
Escrow Agreement, the Deposit Agreement, the Note Purchase Agreement or any
Liquidity Facility to the extent applicable to such Certificateholders or of
modifying in any manner the rights and obligations of such Certificateholders
under this Agreement, the Intercreditor Agreement, the Escrow Agreement, the
Deposit Agreement, the Note Purchase Agreement or any Liquidity Facility;
provided, however, that no such agreement shall, without the consent of the
Certificateholder of each Outstanding Certificate affected thereby:

                 (a)      reduce in any manner the amount of, or delay the
         timing of, any receipt by the Trustee of payments on the Equipment
         Notes held in such Trust or distributions that are required to be made
         herein on any Certificate, or change any date of payment on any
         Certificate, or change the place of payment where, or the coin or
         currency in which, any Certificate is payable, or impair the right to
         institute suit for the enforcement of any such payment or distribution
         on or after the Regular Distribution Date or Special Distribution Date
         applicable thereto; or
<PAGE>   62
                                       56

                 (b)      permit the disposition of any Equipment Note included
         in the Trust Property of such Trust except as permitted by this
         Agreement, or otherwise deprive such Certificateholder of the benefit
         of the ownership of the Equipment Notes in such Trust; or

                 (c)      alter the priority of distributions specified in the
         Intercreditor Agreement in a manner materially adverse to the
         interests of the Certificateholders; or

                 (d)      reduce the specified percentage of the aggregate
         Fractional Undivided Interests of such Trust that is required for any
         such supplemental agreement, or reduce such specified percentage
         required for any waiver (of compliance with certain provisions of this
         Agreement or certain defaults hereunder and their consequences)
         provided for in this Agreement; or

                 (e)      modify any of the provisions of this Section 9.02 or
         Section 6.05, except to increase any such percentage or to provide
         that certain other provisions of this Agreement cannot be modified or
         waived without the consent of the Certificateholder of each
         Certificate affected thereby; or

                 (f)      adversely affect the status of any Trust as a grantor
         trust under Subpart E, Part I of Subchapter J of Chapter 1 of Subtitle
         A of the Internal Revenue Code of 1986, as amended, for U.S. federal
         income tax purposes.

                 It shall not be necessary for any Direction of such
Certificateholders under this Section 9.02 to approve the particular form of
any proposed supplemental agreement, but it shall be sufficient if such
Direction shall approve the substance thereof.

                 Section 9.03.  Documents Affecting Immunity or Indemnity.  If
in the opinion of the Trustee any document required to be executed by it
pursuant to the terms of Section 9.01 or 9.02 affects any interest, right,
duty, immunity or indemnity in favor of the Trustee under this Agreement or any
Trust Supplement, the Trustee may in its discretion decline to execute such
document.

                 Section 9.04.  Execution of Supplemental Agreements.  In
executing, or accepting the additional trusts created by, any supplemental
agreement permitted by this Article or the modifications thereby of the trusts
created by this Agreement, the Trustee shall be entitled to receive, and shall
be fully protected in relying upon, an Opinion of Counsel stating that the
execution of such supplemental agreement is authorized or permitted by this
Agreement.

                 Section 9.05.  Effect of Supplemental Agreements.  Upon the
execution of any agreement supplemental to this Agreement under this Article,
this Agreement shall be
<PAGE>   63
                                       57

modified in accordance therewith, and such supplemental agreement shall form a
part of this Agreement for all purposes; and every Certificateholder
theretofore or thereafter authenticated and delivered hereunder shall be bound
thereby to the extent applicable to such series.

                 Section 9.06.  Conformity with Trust Indenture Act.  Every
supplemental agreement executed pursuant to this Article shall conform to the
requirements of the Trust Indenture Act as then in effect.

                 Section 9.07.  Reference in Certificates to Supplemental
Agreements.  Certificates authenticated and delivered after the execution of
any supplemental agreement  pursuant to this Article may bear a notation in
form approved by the Trustee as to any matter provided for in such supplemental
agreement; and, in such case, suitable notation may be made upon Outstanding
Certificates after proper presentation and demand.


                                   ARTICLE X

                   AMENDMENTS TO INDENTURE AND NOTE DOCUMENTS

                 Section 10.01.  Amendments and Supplements to Indenture and
Other Note Documents.  In the event that the Trustee, as holder (or beneficial
owner through the Subordination Agent) of any Equipment Notes (or as a
prospective purchaser of any Postponed Notes) in trust for the benefit of the
Certificateholders or as Controlling Party under an Intercreditor Agreement,
receives (directly or indirectly through the Subordination Agent) a request for
a consent to any amendment, modification, waiver or supplement under any
Indenture, other Note Document or any other related document, which request
would require the consent of Certificateholders under Section 9.02 hereof, the
Trustee shall forthwith send a notice of such proposed amendment, modification,
waiver or supplement to each Certificateholder registered on the Register as of
the date of such notice.  The Trustee shall request from the Certificateholders
a Direction as to (a) whether or not to take or refrain from taking (or direct
the Subordination Agent to take or refrain from taking) any action which a
holder of (or, with respect to Postponed Notes, a prospective purchaser of)
such Equipment Note or a Controlling Party has the option to direct, (b)
whether or not to give or execute (or direct the Subordination Agent to give or
execute) any waivers, consents, amendments, modifications or supplements as a
holder of (or, with respect to Postponed Notes, a prospective purchaser of)
such Equipment Note or as Controlling Party and (c) how to vote (or direct the
Subordination Agent to vote) any Equipment Note (or, with respect to a
Postponed Note, its commitment to acquire such Postponed Note) if a vote has
been called for with respect thereto.  Provided such a request for
Certificateholder Direction shall have been made, in directing any action or
casting any vote or giving any consent as the holder of any Equipment Note (or
in directing the Subordination Agent in any of the foregoing),
<PAGE>   64
                                       58

(i) other than as Controlling Party, the Trustee shall vote for or give consent
to any such action with respect to such Equipment Note (or Postponed Note) in
the same proportion as that of (A) the aggregate face amounts of all
Certificates actually voted in favor of or for giving consent to such action by
such Direction of Certificateholders to (B) the aggregate face amount of all
Outstanding Certificates and (ii) as Controlling Party, the Trustee shall vote
as directed in such Certificateholder Direction by the Certificateholders
evidencing a Fractional Undivided Interest aggregating not less than a majority
in interest in the Trust.  For purposes of the immediately preceding sentence,
a Certificate shall have been "actually voted" if the Holder of such
Certificate has delivered to the Trustee an instrument evidencing such Holder's
consent to such Direction prior to one Business Day before the Trustee directs
such action or casts such vote or gives such consent.  Notwithstanding the
foregoing, but subject to Section 6.04 and any Intercreditor Agreement, the
Trustee may, with respect to the Certificates, in its own discretion and at its
own direction, consent and notify the relevant Loan Trustee of such consent (or
direct the Subordination Agent to consent and notify the Loan Trustee of such
consent) to any amendment, modification, waiver or supplement under any related
Indenture or any other related Note Document if an Event of Default hereunder
shall have occurred and be continuing or if such amendment, modification,
waiver or supplement will not materially adversely affect the interests of the
Certificateholders.


                                   ARTICLE XI

                             TERMINATION OF TRUSTS

                 Section 11.01.  Termination of the Trust.  The respective
obligations and responsibilities of the Company and the Trustee shall terminate
upon the distribution to all Certificateholders and the Trustee of all amounts
required to be distributed to them pursuant to this Agreement and the
disposition of all property held as part of the Trust Property; provided,
however, that in no event shall the Trust continue beyond one hundred ten (110)
years following the date of the execution of this Agreement.

                 Notice of any termination, specifying the Distribution Date
upon which the Certificateholders may surrender their Certificates to the
Trustee for payment of the final distribution and cancellation, shall be mailed
promptly by the Trustee to Certificateholders not earlier than the 60th day and
not later than the 15th day next preceding such final Distribution Date
specifying (A) the Distribution Date upon which the proposed final payment of
the Certificates will be made upon presentation and surrender of Certificates
at the office or agency of the Trustee therein specified, (B) the amount of any
such proposed final payment, and (c) that the Record Date otherwise applicable
to such Distribution Date is not applicable, payments being made only upon
presentation and surrender of the Certificates at the office or agency of the
Trustee therein specified.  The Trustee shall give such notice to the Registrar
at the time such notice is given to Certificateholders.  Upon presentation and
<PAGE>   65
                                       59

surrender of the Certificates in accordance with such notice, the Trustee shall
cause to be distributed to Certificateholders such final payments.

                 In the event that all of the Certificateholders shall not
surrender their Certificates for cancellation within six months after the date
specified in the above-mentioned written notice, the Trustee shall give a
second written notice to the remaining Certificateholders to surrender their
Certificates for cancellation and receive the final distribution with respect
thereto.  No additional interest shall accrue on the Certificates after the
Distribution Date specified in the first written notice.  In the event that any
money held by the Trustee for the payment of distributions on the Certificates
shall remain unclaimed for two years (or such lesser time as the Trustee shall
be satisfied, after sixty days' notice from the Company, is one month prior to
the escheat period provided under applicable law) after the final distribution
date with respect thereto, the Trustee shall pay to each Loan Trustee the
appropriate amount of money relating to such Loan Trustee and shall give
written notice thereof to the related Owner Trustees, the Owner Participants
and the Company.


                                  ARTICLE XII

                            MISCELLANEOUS PROVISIONS

                 Section 12.01.  Limitation on Rights of Certificateholders.
The death or incapacity of any Certificateholder shall not operate to terminate
this Agreement or the Trust, nor entitle such Certificateholder's legal
representatives or heirs to claim an accounting or to take any action or
commence any proceeding in any court for a partition or winding up of the
Trust, nor otherwise affect the rights, obligations, and liabilities of the
parties hereto or any of them.

                 Section 12.02.  Liabilities of Certificateholders.  Neither
the existence of the Trust nor any provision in this Agreement is intended to
or shall limit the liability the Certificateholders would otherwise incur if
the Certificateholders owned Trust Property as co-owners, or incurred any
obligations of the Trust, directly rather than through the Trust.

                 Section 12.03.  Registration of Equipment Notes in Name of
Subordination Agent.  If the Trust is party to the Intercreditor Agreement, the
Trustee agrees that all Equipment Notes to be purchased by such Trust shall be
issued in the name of the Subordination Agent under the Intercreditor Agreement
or its nominee and held by such Subordination Agent in trust for the benefit of
the Certificateholders, or, if not so held, such Subordination Agent or its
nominee shall be reflected as the owner of such Equipment Notes in the register
of the issuer of such Equipment Notes.

provided above within the time prescribed, it is conclusively presumed to have

IN ACCORDANCE WITH SUCH LAWS.

                 Section 12.06.  Severability of Provisions.  If any one or
more of the covenants, agreements, provisions or terms of this Agreement shall
be for any reason whatsoever held invalid, then such covenants, agreements,
provisions, or terms shall be deemed severable from the remaining covenants,

the validity or enforceability of the other provisions of this Agreement or the
Trust, or of the Certificates or the rights of the Certificateholders thereof.

                 Section 12.07.  Trust Indenture Act Controls.  Upon the
occurrence of any Registration Event, this Agreement shall become subject to
the provisions of the Trust Indenture Act and shall, to the extent applicable,
be governed by such provisions.  From and after any Registration Event, if any
provision of this Agreement limits, qualifies or conflicts with another
provision which is required to be included in this Agreement by the Trust
Indenture Act, the required provision shall control.

                 Section 12.08.  Effect of Headings and Table of Contents.  The
Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

                 Section 12.09.  Successors and Assigns.  All covenants,
agreements, representations and warranties in this Agreement by the Trustee and

                                       62

their successors hereunder, and the Certificateholders, any benefit or any
legal or equitable right, remedy or claim under this Agreement.

                 Section 12.11.  Legal Holidays.  In any case where any Regular
Distribution Date or Special Distribution Date relating to any Certificate
shall not be a Business Day, then (notwithstanding any other provision of this
Agreement) payment need not be made on such date, but may be made on the next
succeeding Business Day with the same force and effect as if made on such
Regular Distribution Date or Special Distribution Date, and no interest shall
accrue during the intervening period.

                 Section 12.12.  Counterparts.  For the purpose of facilitating
the execution of this Agreement and for other purposes, this Agreement may be

shall have the protection afforded by Section 312(c) of the Trust Indenture
Act.

                 Section 12.14.  Intention of Parties.  The parties hereto
intend that each Trust be classified for U.S. federal income tax purposes as a
grantor trust under Subpart E, Part I of Subchapter J of the Internal Revenue
Code of 1986, as amended, and not as a trust or association taxable as a
corporation or as a partnership.  The Trustee agrees to hold all assets of each
Trust for investment purposes only.  Each Certificateholder and Investor, by
its acceptance of its Certificate or a beneficial interest therein, agrees to
treat the Trust as a grantor trust for all U.S. federal, state and local income
tax purposes.  The powers granted and obligations undertaken pursuant to this
Agreement shall be so construed so as to further such intent.

expressed, have been done, performed and fulfilled, and the execution and

                 (d)      a statement as to whether, in the opinion of each
         such individual, such condition or covenant has been complied with.

                 Section 1.03.  Form of Documents Delivered to Trustee.  In any
case where several matters are required to be certified by, or covered by an
opinion of, any specified Person, it is not necessary that all such matters be
certified by, or covered by the opinion of, only one such Person, or that they
be so certified or covered by only one document, but one such Person may
certify or give an opinion with respect to some matters and one or more other
such Persons as to other matters and any such Person may certify or give an
opinion as to such matters in one or several documents.

                 Where any Person is required to make, give or execute two or
more applications, requests, consents, certificates, statements, opinions or
other instruments under this Agreement, they may, but need not, be consolidated
and form one instrument.

                 Section 1.04.  Directions of Certificateholders.  (a)  Any
direction, consent, request, demand, authorization, notice, waiver or other
action provided by this Agreement in respect of the Certificates to be given or
taken by Certificateholders (a "Direction") may be embodied in and evidenced by
one or more instruments of substantially similar tenor signed by such
Certificateholders in person or by an agent or proxy 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,
when it is hereby expressly required pursuant to this Agreement, to the Company
or any Loan Trustee.  Such instrument or instruments (and the action embodied
therein and evidenced thereby) are herein sometimes referred to as the "Act" of
the Certificateholders signing such instrument or instruments.  Proof of
execution of any such instrument or of a writing appointing any such agent or
proxy shall be sufficient for any purpose of this Trust Agreement and
conclusive in favor of the Trustee, the Company and the related Loan Trustee,
if made in the manner provided in this Section 1.04.

                 (b)      The fact and date of the execution by any Person of
any such instrument or writing may be proved by the certificate of any notary
public or other officer of any jurisdiction authorized to take acknowledgments
of deeds or administer oaths that the Person executing such instrument
acknowledged to him the execution thereof, or by an affidavit of a witness to
such execution sworn to before any such notary or such other officer, and where
such execution is by an officer of a corporation or association or a member of
a partnership, on behalf of such corporation, association or partnership, such
<PAGE>   23
                                       17

certificate or affidavit shall also constitute sufficient proof of his
authority.  The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other reasonable manner which the Trustee deems sufficient.

                 (c)      In determining whether the Certificateholders of the
requisite Fractional Undivided Interests of Certificates Outstanding have given
any Direction under this Agreement, Certificates owned by the Company or any
Affiliate thereof shall be disregarded and deemed not to be Outstanding for
purposes of any such determination.  In determining whether the Trustee shall
be protected in relying upon any such Direction, only Certificates which the
Trustee knows to be so owned shall be so disregarded.  Notwithstanding the
foregoing, (i) if any such Person owns 100% of the Certificates Outstanding,
such Certificates shall not be so disregarded, and (ii) if any amount of
Certificates so owned by any such Person have been pledged in good faith, such
Certificates shall not be disregarded if the pledgee establishes to the
satisfaction of the Trustee the pledgee's right so to act with respect to such
Certificates and that the pledgee is not the Company or any Affiliate thereof.

                 (d)      The Company may, at its option, by delivery of an
Officer's Certificate to the Trustee, set a record date to determine the
Certificateholders in respect of the Certificates, entitled to give any
Direction.  Notwithstanding Section 316(c) of the Trust Indenture Act, such
record date shall be the record date specified in such Officer's Certificate,
which shall be a date not more than 30 days prior to the first solicitation of
Certificateholders of the applicable series in connection therewith.  If such a
record date is fixed, such Direction may be given before or after such record
date, but only the Certificateholders of record of the applicable series at the
close of business on such record date shall be deemed to be Certificateholders
for the purposes of determining whether Certificateholders of the requisite
proportion of Outstanding Certificates have authorized or agreed or consented
to such Direction, and for that purpose the Outstanding Certificates shall be
computed as of such record date; provided, however, that no such Direction by
the Certificateholders on such record date shall be deemed effective unless it
shall become effective pursuant to the provisions of this Agreement not later
than one year after such record date.

                 (e)      Any Direction by the Holder of any Certificate shall
bind the Holder of every Certificate issued upon the transfer thereof or in
exchange therefor or in lieu thereof, whether or not notation of such Direction
is made upon such Certificate.

                 (f)      Except as otherwise provided in Section 1.04(c),
Certificates owned by or pledged to any Person shall have an equal and
proportionate benefit under the provisions of this Agreement, without
preference, priority or distinction as among all of the Certificates.

                                   ARTICLE II

                       ORIGINAL ISSUANCE OF CERTIFICATES:
                         ACQUISITION OF TRUST PROPERTY

                 Section 2.01.  Delivery of Documents; Delivery Dates.  (a)
The Trustee is hereby directed (i) to execute and deliver the Intercreditor
Agreement, the Escrow Agreement and the Note Purchase Agreement on or prior to
the Issuance Date, each in the form delivered to the Trustee by the Company and
(ii) subject to the respective terms thereof, to perform its obligations
thereunder.  Upon request of the Company and the satisfaction or waiver of the
closing conditions specified in the Placement Agreement, the Trustee shall
execute, deliver, authenticate, issue and sell Certificates in authorized
denominations equaling in the aggregate the amount set forth, with respect to
the Trust, in Schedule II to the Placement Agreement evidencing the entire
ownership interest in the Trust, which amount equals the maximum aggregate
principal amount of Equipment Notes which may be purchased by the Trustee
pursuant to the Note Purchase Agreement.  Except as provided in Sections 3.04
and 3.07 of this Agreement, the Trustee shall not execute, authenticate or
deliver Certificates in excess of the aggregate amount specified in this
paragraph.

                 (b)      On or after the Issuance Date, the Company may
deliver from time to time to the Trustee a Delivery Notice relating to one or
more Equipment Notes.  After receipt of a Delivery Notice and in any case no
later than one Business Day prior to a Delivery Date as to which such Delivery
Notice relates (the "Applicable Delivery Date"), the Trustee shall (as and when
specified in the Delivery Notice) instruct the Escrow Agent to provide a Notice
of Purchase Withdrawal to the Depositary requesting (A) the withdrawal of one
or more Deposits on the Applicable Delivery Date in accordance with and to the
extent permitted by the terms of the Escrow Agreement and the Deposit Agreement
and (B) the payment of all, or a portion, of such Deposit or Deposits in an
amount equal in the aggregate to the purchase price of such Equipment Notes to
or on behalf of the Owner Trustee or the Company, as the case may be, issuing
such Equipment Notes, all as shall be described in the Delivery Notice.  The
Trustee shall (as and when specified in such Delivery Notice), subject to the
conditions set forth in Section 2 of the Note Purchase Agreement, enter into
and perform its obligations under the Participation Agreement specified in such
Delivery Notice (the "Applicable Participation Agreement") and cause such
certificates, documents and legal opinions relating to the Trustee to be duly
delivered as required by the Applicable Participation Agreement.  If at any
time prior to the Applicable Delivery Date, the Trustee receives a notice of
postponement pursuant to Section 1(e) or 1(f) of the Note Purchase Agreement,
then the Trustee shall give the Depositary (with a copy to the Escrow Agent) a
notice of cancellation of such Notice of Purchase Withdrawal relating to such
Deposit or Deposits on such Applicable Delivery Date.  Upon satisfaction of the
conditions specified in the Note Purchase Agreement and the Applicable
Participation Agreement, the Trustee shall
<PAGE>   25
                                       19

purchase the applicable Equipment Notes with the proceeds of the withdrawals of
one or more Deposits made on the Applicable Delivery Date in accordance with
the terms of the Deposit Agreement and the Escrow Agreement.  The purchase
price of such Equipment Notes shall equal the principal amount of such
Equipment Notes.  Amounts withdrawn from such Deposit or Deposits in excess of
the purchase price of the Equipment Notes or to the extent not applied on the
Applicable Delivery Date to the purchase price of the Equipment Notes, shall be
re-deposited by the Trustee with the Depositary on the Applicable Delivery Date
in accordance with the terms of the Deposit Agreement.

                 Section 2.02.  Withdrawal of Deposits.  If any Deposits remain
outstanding on the Business Day next succeeding the Cut-off Date, (i) the
Trustee shall give the Escrow Agent notice that the Trustee's obligation to
purchase Equipment Notes under the Note Purchase Agreement has terminated and
instruct the Escrow Agent to provide a notice of Final Withdrawal to the
Depositary substantially in the form of Exhibit B to the Deposit Agreement (the
"Final Withdrawal Notice") and (ii) the Trustee will make a demand upon the
Company under the Note Purchase Agreement for an amount equal to the Special
Redemption Premium, such payment to be made on the Final Withdrawal Date.

                 Section 2.03.  Acceptance by Trustee.  The Trustee, upon the
execution and delivery of this Agreement, acknowledges its acceptance of all
right, title and interest in and to the Trust Property and will hold such
right, title and interest for the benefit of all then present and future
Certificateholders, upon the trusts herein set forth.  By its payment for and
acceptance of each Certificate issued to it under this Agreement, each initial
Holder of such Certificate as grantor of such Trust shall thereby join in the
creation and declaration of such Trust.

                 Section 2.04.  Limitation of Powers.  The Trust is constituted
solely for the purpose of making the investment in the Equipment Notes, and,
except as set forth herein, the Trustee shall not be authorized or empowered to
acquire any other investments or engage in any other activities and, in
particular, the Trustee shall not be authorized or empowered to do anything
that would cause such Trust to fail to qualify as a "grantor trust" for federal
income tax purposes (including, as subject to this restriction, acquiring any
Aircraft (as defined in the respective Indentures) by bidding such Equipment
Notes or otherwise, or taking any action with respect to any such Aircraft once
acquired).

the U.S. Global Certificate may from time to time be increased or decreased by
adjustments made on the records of the Depositary or its nominee, or of the
Trustee, as custodian for the Depositary or its nominee, as hereinafter
provided.

                 (d)      Initial Certificates offered and sold in offshore

<PAGE>   27
                                       21

Depositary.  At any time following March 21, 1998 (the "Offshore Certificates

and authenticated by the Trustee as hereinafter provided, shall be registered
in the name of a nominee for the Depositary and deposited with the Trustee, as
custodian for the Depositary, and the Registrar shall reflect on its books and
records the date of such transfer and a decrease in the principal amount of any
Temporary Offshore Global Certificate in an amount equal to the principal
amount of the beneficial interest in such Temporary Offshore Global Certificate
transferred.  The U.S. Global Certificate and the Offshore Global Certificates
are sometimes referred to as the "Global Certificates".

                 (e)      Initial Certificates offered and sold to
Institutional Accredited Investors shall be issued in the form of permanent
certificated Certificates in registered form in substantially the form set

relating to the nature of the Exchange Certificates as the Responsible Officer
of the Trustee executing such Exchange Certificates on behalf of the Trust may
determine, as evidenced by such officer's execution on behalf of the Trust of
such Exchange Certificates.  Such Global Exchange Certificates shall be in
registered form and be registered in the name of DTC and deposited with the
Trustee, at its Corporate Trust Office, as custodian for DTC.  The aggregate
principal amount of any Global Exchange Certificate may from time to time be
increased or decreased by adjustments made on the records of the Trustee, as
custodian for DTC for such Global Exchange Certificate, which adjustments shall
be conclusive as to the aggregate principal amount of any such Global Exchange
Certificate.  Subject to clause (i) and (ii)  of the first sentence of this
Section 3.01(f), the terms hereof applicable to Restricted Global Certificates
and/or Global Certificates shall apply to the Global Exchange Certificates,

each Global Certificate (other than the Permanent Offshore Global Certificate)
and each U.S. Physical Certificate shall bear the following legend (the
"Private Placement Legend") on the face thereof:

         "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER
         THE SECURITIES ACT.  THE PASS THROUGH TRUST AGREEMENT CONTAINS A
         PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF
         THIS CERTIFICATE IN VIOLATION OF THE FOREGOING RESTRICTIONS.

                 (b)      Each Global Certificate shall also bear the following
legend on the face thereof:

         OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO
         THE TRUSTEE OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR
         PAYMENT, AND ANY CERTIFICATE ISSUED IN EXCHANGE FOR THIS CERTIFICATE
         IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS
         REQUESTED BY AN AUTHORIZED  REPRESENTATIVE OF DTC (AND ANY PAYMENT
         HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED
         BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER
         USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL
         INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST

         WHOLE, BUT NOT IN PART, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF
         OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL
         CERTIFICATE SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE

                 Section 3.03.  Authentication of Certificates.  (a)  On the
Issuance Date, the Trustee shall duly execute, authenticate and deliver
Certificates in authorized denominations equalling in the aggregate the amount
set forth, with respect to the Trust, in Schedule II to the Placement
Agreement, evidencing the entire ownership of the Trust, which amount equals
the maximum aggregate principal amount of the Equipment Notes which may be
purchased by the Trustee pursuant to the Note Purchase Agreement.

                 (b)      No Certificate shall be entitled to any benefit under
this Agreement or be valid or obligatory for any purpose, unless there appears
on such Certificate a certificate of authentication substantially in the form
provided for herein executed by the Trustee by the manual signature of one of
its authorized signatories, and such certificate upon any Certificate shall be
conclusive evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder.

                 Section 3.04.  Transfer and Exchange.  The Trustee shall cause
to be kept at the office or agency to be maintained by it in accordance with
the provisions of Section 7.12 of this Agreement a register (the "Register")
for the Certificates in which, subject to such reasonable regulations as it may
prescribe, the Trustee shall provide for the registration of the Certificates
and of transfers and exchanges of the Certificates as herein provided.  The
Trustee shall initially be the registrar (the "Registrar") for the purpose of
registering the Certificates and transfers and exchanges of the Certificates as
herein provided.  A Certificateholder may transfer a Certificate by written
application to the Registrar stating the name of the proposed transferee and
otherwise complying with the terms of this Agreement, including providing a
written certificate or other evidence of compliance with any restrictions on
transfer.  No such transfer shall be effected until, and such transferee shall
succeed to the rights of a Certificateholder only upon, final acceptance and
registration of the transfer by the Registrar in the Register.  Prior to the
registration of any transfer by a Certificateholder as provided herein, the
Trustee shall treat the person in whose name the Certificate is registered as
the owner thereof for all purposes, and the Trustee shall not be affected by
notice to the contrary.  Furthermore, the Depositary shall, by acceptance of a
Global Certificate, agree that transfers of beneficial interests in such Global
Certificate may be effected only through a book-entry system maintained by the
Depositary (or its agent), and that ownership of a beneficial interest in the
Certificate shall be required to be reflected in a book entry.  When
Certificates are presented to the Registrar with a request to register the
transfer or to exchange them for an equal face amount of Certificates of other
authorized denominations, the Registrar shall register the transfer or make the
exchange as requested if its requirements for such transactions are met.  To
permit registrations of transfers and exchanges in accordance with the terms,
conditions and restrictions hereof, the Trustee shall execute and authenticate
Certificates at the Registrar's request.  No service charge shall be made for
any registration of transfer or exchange of the Certificates, but the Trustee
may require payment by the transferor of a sum sufficient to cover any transfer
tax or similar governmental charge payable in connection therewith (other than
any such transfer taxes or
<PAGE>   31
                                       25

other similar governmental charges payable upon exchanges pursuant to Section
3.10 or 9.07).

                 Section 3.05.  Book-Entry Provisions for U.S. Global
Certificate and Offshore Global Certificates.  (a) Members of, or participants
in, the Depositary ("Agent Members") shall have no rights under this Agreement
with respect to any Global Certificate held on their behalf by the Depositary,
or the Trustee as its custodian, and the Depositary may be treated by the
Trustee and any agent of the Trustee as the absolute owner of such Global
Certificate for all purposes whatsoever.  Notwithstanding the foregoing,
nothing herein shall prevent the Trustee or any agent of the Trustee from
giving effect to any written certification, proxy or other authorization
furnished by the Depositary or shall 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 Certificate.  Upon the issuance of any Global
Certificate, the Registrar or its duly appointed agent shall record a nominee
of the Depositary as the registered holder of such Global Certificate.

                 (b)      Transfers of any Global Certificate shall be limited
to transfers of such Global Certificate or Offshore Global Certificate in
whole, but not in part, to nominees of the Depositary, its successor or such
successor's nominees.  Beneficial interests in the U.S. Global Certificate and
any Offshore Global Certificate may be transferred in accordance with the rules
and procedures of the Depositary and the provisions of Section 3.06.
Beneficial interests in the U.S. Global Certificate or an Offshore Global
Certificate shall be delivered to all beneficial owners in the form of U.S.
Physical Certificates or Offshore Physical Certificates, as the case may be, if
(i) the Depositary notifies the Trustee that it is unwilling or unable to
continue as Depositary for the U.S. Global Certificate or such Offshore Global
Certificate, as the case may be, and a successor depositary is not appointed by
the Trustee within 90 days of such notice or (ii) an Event of Default has
occurred and is continuing and the Registrar has received a request from the
Depositary to issue Physical Certificates.

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

                 (d)      In connection with the transfer of the entire U.S.
Global Certificate or an entire Offshore Global Certificate to the beneficial
owners thereof pursuant to paragraph (b) of this Section 3.05, such U.S. Global
Certificate or Offshore Global Certificate, as the case may be, shall be deemed
to be surrendered to the Trustee for cancellation, and the Trustee shall
execute, authenticate and deliver, to each beneficial owner identified by the
Depositary in exchange for its beneficial interest in such U.S. Global
Certificate or Offshore
<PAGE>   32
                                       26

Global Certificate, as the case may be, an equal aggregate principal amount of
U.S. Physical Certificates or Offshore Physical Certificates, as the case may
be, of authorized denominations.

                 (e)      Any U.S. Physical Certificate delivered in exchange
for an interest in the U.S. Global Certificate pursuant to paragraph (b) of
this Section 3.05 shall, except as otherwise provided by paragraph (f) of
Section 3.06, bear the Private Placement Legend.

                 (f)      Any Offshore Physical Certificate delivered in
exchange for an interest in an Offshore Global Certificate pursuant to
paragraph (b) of this Section shall, except as otherwise provided by paragraph
(f) of Section 3.06, bear the applicable legend regarding transfer restrictions
set forth in Section 3.02(a).

                 (g)      The registered holder of the U.S. Global Certificate
or any Offshore Global Certificate 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
Agreement or the Certificates.

                 Section 3.06.  Special Transfer Provisions.  Unless and until
(i) an Initial Certificate is sold under an effective Registration Statement,
or (ii) an Initial Certificate is exchanged for an Exchange Certificate
pursuant to an effective Exchange Offer Registration Statement, in each case
pursuant to the Registration Rights Agreement, the following provisions shall
apply to such Initial Certificates:

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

                          (i)     The Registrar shall register the transfer of
                 any Certificate, whether or not such Certificate bears the
                 Private Placement Legend, if (x) the requested transfer is at
                 least three years after the later of the original issue date
                 of the Certificates and the last date on which such
                 Certificate was held by the Company or any affiliate of any
                 such persons or (y) the proposed transferee has delivered to
                 the Registrar a letter substantially in the form of Exhibit D
                 hereto and the aggregate principal amount of the Certificates
                 being transferred is at least $100,000.

                          (ii)    If the proposed transferor is an Agent Member
                 holding a     beneficial interest in the U.S. Global
                 Certificate, 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
<PAGE>   33
                                       27

                 Registrar shall reflect on its books and records the date of
                 the transfer and a decrease in the principal amount of such
                 U.S. Global Certificate in an amount equal to the principal
                 amount of the beneficial interest in such U.S. Global
                 Certificate to be transferred, and the Company shall execute,
                 and the Trustee shall authenticate and deliver to the
                 transferor or at its direction, one or more U.S.  Physical
                 Certificates of like tenor and amount.

                 (b)      Transfers to QIBs.  The following provisions shall
         apply with respect to the registration of any proposed transfer of an
         Initial Certificate to a QIB (excluding Non-U.S. Persons):

                          (i)     If the Certificate to be transferred consists
                 of U.S. Physical  Certificates or an interest in any Temporary
                 Offshore Global Certificate, 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
                 Initial Certificate stating, or has otherwise advised the
                 Trustee 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 Initial Certificate stating, or has otherwise
                 advised the Trustee and the Registrar in writing, that it is
                 purchasing the Initial Certificate for its own account or an
                 account with respect to which it exercises sole investment
                 discretion and that it, or the Person on whose behalf it is
                 acting with respect to 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 Trust and/or 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.

                          (ii)    Upon receipt by the Registrar of the
                 documents referred to in clause (i) above and instructions
                 given in accordance with the Depositary's and the Registrar's
                 procedures therefor, the Registrar shall reflect on its books
                 and records the date of such transfer and an increase in the
                 principal amount of the U.S. Global Certificate in an amount
                 equal to the principal amount of the U.S.  Physical
                 Certificates or interests in the Temporary Offshore Global
                 Certificate, as the case may be, being transferred, and the
                 Trustee shall cancel such Physical Certificates or decrease
                 the amount of such Temporary Offshore Global Certificate so
                 transferred.

                 (c)      Transfers of Interests in the Permanent Offshore
         Global Certificate or Offshore Physical Certificates.  The Registrar
         shall register any transfer of interests in
<PAGE>   34
                                       28

         the Permanent Offshore Global Certificate or Offshore Physical
         Certificates without requiring any additional certification.

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

                          (i)     Prior to the Offshore Certificates Exchange
                 Date, the Registrar shall register any proposed transfer of an
                 Initial Certificate to a Non-U.S. Person upon receipt of a
                 certificate substantially in the form set forth as Exhibit C
                 hereto from the proposed transferor.

                          (ii)    On and after the Offshore Certificates
                 Exchange Date, the Registrar shall register any proposed
                 transfer to any Non-U.S. Person if the Certificate to be
                 transferred is a U.S. Physical Certificate or an interest in
                 the U.S. Global Certificate, upon receipt of a certificate
                 substantially in the form of Exhibit C from the proposed
                 transferor.  The Registrar shall promptly send a copy of such
                 certificate to the Company.

                          (iii)   Upon receipt by the Registrar of (x) the
                 documents, if any, required by paragraph (ii) 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 of such transfer and a decrease in
                 the principal amount of such U.S. Global Certificate in an
                 amount equal to the principal amount of the beneficial
                 interest in such U.S. Global Certificate to be transferred,
                 and (B) 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 Certificate in an amount equal to the
                 principal amount of the U.S. Physical Certificate or the U.S.
                 Global Certificate, as the case may be, to be transferred, and
                 the Trustee shall cancel the Physical Certificate, if any, so
                 transferred or decrease the amount of such U.S. Global
                 Certificate.

                 (e)      Private Placement Legend.  Upon the transfer,
         exchange or replacement of Certificates not bearing the Private
         Placement Legend, the Registrar shall deliver Certificates that do not
         bear the Private Placement Legend.  Upon the transfer, exchange or
         replacement of Certificates bearing the Private Placement Legend, the
         Registrar shall deliver only Certificates that bear the Private
         Placement Legend unless either (i) the circumstances contemplated by
         paragraph (a)(i)(x) or (e)(ii) of this Section 3.06 exist or (ii)
         there is delivered to the Registrar an Opinion of Counsel to
<PAGE>   35
                                       29

         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 Certificate
         bearing the Private Placement Legend, each Holder of such a
         Certificate acknowledges the restrictions on transfer of such
         Certificate set forth in this Agreement and agrees that it will
         transfer such Certificate only as provided in this Agreement.  The
         Registrar shall not register a transfer of any Certificate unless such
         transfer complies with the restrictions on transfer of such
         Certificate set forth in this Agreement.  In connection with any
         transfer of Certificates, each Certificateholder agrees by its
         acceptance of the Certificates to furnish the Registrar or the Trustee
         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 the sufficiency of any
         such certifications, legal opinions or other information.

                 Until such time as no Certificates remain Outstanding, the
Registrar shall retain copies of all letters, notices and other written
communications received pursuant to Section 3.05 or this Section 3.06.  The
Trustee, if not the Registrar at such time, 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 3.07.  Mutilated, Destroyed, Lost or Stolen
Certificates.  If (a) any mutilated Certificate is surrendered to the Registrar
or the Registrar receives evidence to its satisfaction of the destruction, loss
or theft of any Certificate and (b) there is delivered to the Registrar and the
Trustee such security, indemnity or bond, as may be required by them to save
each of them harmless, then, in the absence of notice to the Registrar or the
Trustee that such destroyed, lost or stolen Certificate has been acquired by a
bona fide purchaser, and provided that the requirements of Section 8-405 of the
Uniform Commercial Code in effect in any applicable jurisdiction are met, the
Trustee shall execute, authenticate and deliver, in exchange for or in lieu of
any such mutilated, destroyed, lost or stolen Certificate, a new Certificate or
Certificates, in authorized denominations and of like Fractional Undivided
Interest and bearing a number not contemporaneously outstanding.

                 In connection with the issuance of any new Certificate under
this Section 3.07, the Trustee may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Trustee
and the Registrar) connected therewith.
<PAGE>   36
                                       30

                 Any duplicate Certificate issued pursuant to this Section 3.07
shall constitute conclusive evidence of the appropriate Fractional Undivided
Interest in the Trust, as if originally issued, whether or not the lost, stolen
or destroyed Certificate shall be found at any time.

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

                 Section 3.08.  Persons Deemed Owners.  Prior to due
presentment of a Certificate for registration of transfer, the Trustee, the
Registrar and any Paying Agent may treat the Person in whose name any
Certificate is registered (as of the day of determination) as the owner of such
Certificate for the purpose of receiving distributions pursuant to Article IV
and for all other purposes whatsoever, and none of the Trustee, the Registrar
or any Paying Agent shall be affected by any notice to the contrary.

                 Section 3.09.  Cancellation.  All Certificates surrendered for
payment or transfer or exchange shall, if surrendered to the Trustee or any
agent of the Trustee other than the Registrar, be delivered to the Registrar
for cancellation and shall promptly be cancelled by it.  No Certificates shall
be authenticated in lieu of or in exchange for any Certificates cancelled as
provided in this Section, except as expressly permitted by this Agreement.  All
cancelled Certificates held by the Registrar shall be destroyed and a
certification of their destruction delivered to the Trustee.

                 Section 3.10.  Temporary Certificates.  Until definitive
Certificates are ready for delivery, the Trustee shall authenticate temporary
Certificates.  Temporary Certificates shall be substantially in the form of
definitive Certificates but may have insertions, substitutions, omissions and
other variations determined to be appropriate by the officers executing the
temporary Certificates, as evidenced by their execution of such temporary
Certificates.  If temporary Certificates are issued, the Trustee will cause
definitive Certificates to be prepared without unreasonable delay.  After the
preparation of definitive Certificates, the temporary Certificates shall be
exchangeable for definitive Certificates upon surrender of the temporary
Certificates at the office or agency of the Trustee designated for such purpose
pursuant to Section 7.12, without charge to the Certificateholder.  Upon
surrender for cancellation of any one or more temporary Certificates, the
Trustee shall execute, authenticate and deliver in exchange therefor a like
face amount of definitive Certificates of authorized denominations.  Until so
exchanged, the temporary Certificates shall be entitled to the same benefits
under this Agreement as definitive Certificates.

                 Section 3.11.  Limitation of Liability for Payments.  All
payments and distributions made to Certificateholders shall be made only from
the Trust Property and only to the extent that the Trustee shall have
sufficient income or proceeds from the Trust
<PAGE>   37
                                       31

Property to make such payments in accordance with the terms of Article IV of
this Agreement.  Each Certificateholder, by its acceptance of a Certificate,
agrees that it will look solely to the income and proceeds from the Trust
Property for any payment or distribution due to such Certificateholder pursuant
to the terms of this Agreement and that it will not have any recourse to the
Company, the Trustee, the Loan Trustees, the Liquidity Providers, the Owner
Trustees or the Owner Participants, except as otherwise expressly provided
herein or in the Intercreditor Agreement.

                 The Company is a party to this Agreement solely for purposes
of meeting the requirements of the Trust Indenture Act, and therefore shall not
have any right, obligation or liability hereunder (except as otherwise
expressly provided herein).

Certificateholders a Certificate Account as one or more non-interest-bearing
accounts.  The Trustee shall hold such Certificate Account in trust for the

Account.

                 (b)      The Trustee shall establish and maintain on behalf of

Trustee shall hold the Special Payments Account in trust for the benefit of the
Certificateholders and shall make or permit withdrawals therefrom only as
provided in this Agreement.  On each day when one or more Special Payments are
made to the Trustee under the Intercreditor Agreement and upon payment of the
Special Redemption Premium to the Trustee under the Note Purchase Agreement
with respect to the Certificates, the Trustee, upon receipt thereof, shall
immediately deposit the aggregate amount of such Special Payments in such
Special Payments Account.

                 (c)      The Trustee shall present (or, if applicable, cause
the Subordination Agent to present) to the related Loan Trustee of each
Equipment Note such Equipment Note on the date of its stated final maturity or,
in the case of any Equipment Note which is to be

                                       32

redeemed in whole pursuant to the related Indenture, on the applicable
redemption date under such Indenture.

                 Section 4.02.  Distributions from Certificate Account and
Special Payments Account.  (a)  On each Regular Distribution Date with respect
to a series of Certificates or as soon thereafter as the Trustee has confirmed
receipt of the payment of all or any part of the Scheduled Payments due on the
Equipment Notes held (subject to the Intercreditor Agreement) in the related
Trust on such date, the Trustee shall distribute out of the applicable
Certificate Account the entire amount deposited therein pursuant to Section
4.01(a).  There shall be so distributed to each Certificateholder of record of
such series on the Record Date with respect to such Regular Distribution Date
(other than as provided in Section 11.01 concerning the final distribution) by
check mailed to such Certificateholder, at the address appearing in the
Register, such Certificateholder's pro rata share (based on the Fractional
Undivided Interest in the Trust held by such Certificateholder) of the total
amount in the applicable Certificate Account, except that, with respect to
Certificates registered on the Record Date in the name of a Clearing Agency (or
its nominee), such distribution shall be made by wire transfer in immediately
available funds to the account designated by such Clearing Agency (or such
nominee).

                 (b)      On each Special Distribution Date with respect to any
Special Payment with respect to the Certificates or as soon thereafter as the
Trustee has confirmed receipt of any Special Payments due on the Equipment
Notes held (subject to the Intercreditor Agreement) in the related Trust or
realized upon the sale of such Equipment Notes or receipt of the Special
Redemption Premium, the Trustee shall distribute out of the applicable Special
Payments Account the entire amount of such applicable Special Payment deposited
therein pursuant to Section 4.01(b).  There shall be so distributed to each
Certificateholder of record of such series on the Record Date with respect to
such Special Distribution Date (other than as provided in Section 11.01
concerning the final distribution) by check mailed to such Certificateholder,
at the address appearing in the Register, such Certificateholder's pro rata
share (based on the Fractional Undivided Interest in the related Trust held by
such Certificateholder) of the total amount in the applicable Special Payments
Account on account of such Special Payment, except that, with respect to
Certificates registered on the Record Date in the name of a Clearing Agency (or
its nominee), such distribution shall be made by wire transfer in immediately
available funds to the account designated by such Clearing Agency (or such
nominee).

                 (c)      The Trustee shall, at the expense of the Company,
cause notice of each Special Payment with respect to a series of Certificates
to be mailed to each Certificateholder at his address as it appears in the
Register.  In the event of redemption or purchase of Equipment Notes held in
the related Trust, such notice shall be mailed not less than 15 days prior to
the Special Distribution Date for the Special Payment resulting from such
redemption or purchase, which Special Distribution Date shall be the date of
such redemption or
<PAGE>   39
                                       33

purchase.  In the event that any Special Redemption Premium is to be paid by
the Company to the Trustee under the Note Purchase Agreement, such notice shall
be mailed, together with the notice by the Escrow Paying Agent under Section
2.06 of the Escrow Agreement, not less than 20 days prior to the Special
Distribution Date for such amount, which Special Distribution Date shall be the
Final Withdrawal Date.  In the case of any other Special Payments, such notice
shall be mailed as soon as practicable after the Trustee has confirmed that it
has received funds for such Special Payment, stating the Special Distribution
Date for such Special Payment which shall occur not less than 15 days after the
date of such notice and as soon as practicable thereafter.  Notices mailed by
the Trustee shall set forth:

                 (i)      the Special Distribution Date and the Record Date
         therefor (except as otherwise provided in Section 11.01);

                 (ii)     the amount of the Special Payment for each $1,000
         face amount Certificate and the amount thereof constituting principal,
         premium, if any, and interest;

                 (iii)    the reason for the Special Payment; and

                 (iv)     if the Special Distribution Date is the same date as
         a Regular Distribution Date for the Certificates, the total amount to
         be received on such date for each $1,000 face amount Certificate.

If the amount of (i) premium, if any, payable upon the redemption or purchase
of an Equipment Note or (ii) the Special Redemption Premium, if any, has not
been calculated at the time that the Trustee mails notice of a Special Payment,
it shall be sufficient if the notice sets forth the other amounts to be
distributed and states that any premium received will also be distributed.

                 If any redemption of the Equipment Notes held in any Trust is
cancelled, the Trustee, as soon as possible after learning thereof, shall cause
notice thereof to be mailed to each Certificateholder at its address as it
appears on the Register.

                 Section 4.03.  Statements to Certificateholders.  (a)  On each
Regular Distribution Date and Special Distribution Date, the Trustee will

Special Redemption Premium, reflecting in part the information provided by the
Escrow Paying Agent under the Escrow Agreement).  Such statement shall set
forth (per $1,000 aggregate principal amount of Certificate as to (ii), (iii),
(iv) and (v) below) the following information:

         Distribution Date under the Agreement and under the Escrow Agreement,
         indicating the amount allocable to each source;

                 (ii)     the amount of such distribution under this Agreement
         allocable to principal and the amount allocable to premium (including
         the Special Redemption Premium), if any;

                 (iii)    the amount of such distribution under this Agreement
         allocable to interest;

                 (iv)     the amount of such distribution under the Escrow
         Agreement allocable to interest;

                 (v)      the amount of such distribution under the Escrow
         Agreement allocable to Deposits; and

Record Date.  On each Distribution Date, the Trustee will mail to each such
Clearing Agency Participant the statement described above and will make
available additional copies as requested by such Clearing Agency Participant
for forwarding to holders of interests in the Certificates.

                 (b)      Within a reasonable period of time after the end of
each calendar year but not later than the latest date permitted by law, the
Trustee shall furnish to each Person who at any time during such calendar year
was a Certificateholder of record a statement containing the sum of the amounts
determined pursuant to clauses (a)(i), (a)(ii), (a)(iii), (a)(iv) and (a)(v)
above with respect to the related Trust for such calendar year or, in the event
such Person was a Certificateholder of record during a portion of such calendar
year, for the applicable portion of such year, and such other items as are
readily available to the Trustee and which a Certificateholder shall reasonably
request as necessary for the purpose of such Certificateholder's preparation of
its federal income tax returns.  Such statement and such other items shall be
prepared on the basis of information supplied to the Trustee by the Clearing
Agency Participants and shall be delivered by the Trustee to such Clearing
Agency Participants to be available for forwarding by such Clearing Agency
Participants to the holders of interests in the Certificates in the manner
described in Section 4.03(a).

                 (c)      Promptly following (i) the Delivery Period
Termination Date, if there has been any change in the information set forth in

the Delivery Period Termination Date, (y) the related Pool Factors for such
Regular Distribution Dates and (z) the expected principal distribution schedule
of the Equipment Notes, in the aggregate, held as Trust Property at the date of

Clearing Agency, on the Delivery Period Termination Date, the Trustee will
request from such Clearing Agency a securities position listing setting forth
the names of all Clearing Agency Participants reflected on such Clearing
Agency's books as holding interests in the Certificates on such date.  The
Trustee will mail to each such Clearing Agency Participant the statement
described above and will make available additional copies as requested by such
Clearing Agency Participant for forwarding to holders of interests in the
Certificates.

money received by the Trustee pursuant to Section 4.01(b) representing a
Special Payment which is not distributed on the date received shall, to the
extent practicable, be invested in Permitted Investments by the Trustee pending
distribution of such Special Payment pursuant to Section 4.02.  Any investment
made pursuant to this Section 4.04 shall be in such Permitted Investments
having maturities not later than the date that such moneys are required to be
used to make the payment required under Section 4.02 on the applicable Special
Distribution Date and the Trustee shall hold any such Permitted Investments
until maturity.  The Trustee shall have no liability with respect to any

willful misconduct or negligence of the Trustee.  All income and earnings from
such investments shall be distributed on such Special Distribution Date as part
of such Special Payment.

                 Section 5.02.  Consolidation, Merger, Etc.  The Company shall
not consolidate with or merge into any other corporation or convey, transfer or
lease substantially all of its assets as an entirety to any Person unless:

                 (a)      the corporation formed by such consolidation or into
         which the Company is merged or the Person that acquires by conveyance,
         transfer or lease substantially all of the assets of the Company as an

         which the Company is merged or the Person which acquires by
         conveyance, transfer or lease substantially all of the assets of the

         applicable to the Certificates a duly authorized, valid, binding and
         enforceable agreement in form and substance reasonably satisfactory to
         the Trustee containing an assumption by such successor corporation or
         Person of the due and punctual performance and observance of each
         covenant and condition of the Note Documents and of this Agreement

applicable to the Certificates with the same effect as if such successor

Person which shall have become such in the manner prescribed in this Section

                                    DEFAULT

                 Section 6.01.  Events of Default.  (a)  Exercise of Remedies.
Upon the occurrence and during the continuation of any Indenture Default under
any Indenture, the Trustee may, to the extent it is the Controlling Party at
such time (as determined pursuant to the Intercreditor Agreement), direct the
exercise of remedies as provided in the Intercreditor Agreement.

                 (b)      Purchase Rights of Certificateholders.  By acceptance
of its Certificate, each Certificateholder agrees that at any time after the
occurrence and during the continuation of a Triggering Event, each Class D
Certificateholder shall have the right to purchase all, but not less than all,
of the Certificates, the Class A Certificates and the Class B Certificates upon
ten days' written notice to the Trustee, the Class A Trustee, the Class B
Trustee and each other Class D Certificateholder, provided that (A) if prior to
the end of such ten-day period any other Class D Certificateholder notifies
such purchasing Class D Certificateholder that such other Class D
Certificateholder wants to participate in such purchase, then such other Class
D Certificateholder may join with the purchasing Class D Certificateholder to
purchase all, but not less than all, of the Certificates, the Class A
Certificates and the Class B Certificates pro rata based on the Fractional
Undivided Interest in the Class D Trust held by each such Class D
Certificateholder and (B) if prior to the end of such ten-day period any other
Class D Certificateholder fails to notify the purchasing Class D
Certificateholder of such other Class D Certificateholder's desire to
participate in such a purchase, then such other Class D Certificateholder shall
lose its right to purchase the Certificates pursuant to this Section 6.01(b).

                 The purchase price with respect to the Certificates shall be
equal to the Pool Balance of the Certificates, together with accrued and unpaid
interest thereon to the date of such purchase, without premium, but including
any other amounts then due and payable to the Certificateholders under this
Agreement, the Intercreditor Agreement, the Escrow Agreement or any Note
Document or on or in respect of the Certificates; provided, however, that (i)
if such purchase occurs after the record date specified in Section 2.03(b) of
the Escrow Agreement relating to the distribution of unused Deposits and
accrued and unpaid interest thereunder, such purchase price shall be reduced by
the aggregate amount of unused Deposits and interest to be distributed under
the Escrow Agreement (which deducted amounts shall remain distributable to, and
may be retained by, the Certificateholder as of such Record Date) and (ii) if
such purchase occurs after a Record Date, such purchase price shall be reduced
by the amount to be distributed hereunder on the related Distribution Date
(which deducted amounts shall remain distributable to, and may be retained by,
the Certificateholder as of such Record Date); provided further that no such
purchase of Certificates shall be
<PAGE>   44
                                       38

effective unless the purchaser(s) shall certify to the Trustee that
contemporaneously with such purchase, such purchaser(s) is purchasing, pursuant
to the terms of this Agreement and the Other Agreements, the Certificates, the
Class A Certificates and the Class B Certificates which are senior to the
securities held by such purchaser(s).  Each payment of the purchase price of
the Certificates referred to in the first sentence hereof shall be made to an
account or accounts designated by the Trustee and each such purchase shall be
subject to the terms of this Section 6.01(b).  Each Certificateholder agrees by
its acceptance of its Certificate that it will, subject to Section 3.04 of this
Agreement, upon payment from such Class D Certificateholder(s), as the case may
be, of the purchase price set forth in the first sentence of this paragraph,
forthwith sell, assign, transfer and convey to the purchaser(s) thereof
(without recourse, representation or warranty of any kind except for its own
acts), all of the right, title, interest and obligation of such
Certificateholder in this Agreement, the Escrow Agreement, the Deposit
Agreement, the Intercreditor Agreement, the Liquidity Facilities, the Note
Documents and all Certificates and Escrow Receipts held by such
Certificateholder (excluding all right, title and interest under any of the
foregoing to the extent such right, title or interest is with respect to an
obligation not then due and payable as respects any action or inaction or state
of affairs occurring prior to such sale) and the purchaser shall assume all of
such Certificateholder's obligations under this Agreement, the Escrow
Agreement, the Deposit Agreement, the Intercreditor Agreement, the Liquidity
Facilities, the Note Documents and all such Certificates and Escrow Receipts.
The Certificates will be deemed to be purchased on the date payment of the
purchase price is made notwithstanding the failure of the Certificateholders to
deliver any Certificates and, upon such a purchase, (i) the only rights of the
Certificateholders will be to deliver the Certificates to the purchaser(s) and
receive the purchase price for such Certificates and (ii) if the purchaser(s)
shall so request, such Certificateholder will comply with all the provisions of
Section 3.04 of this Agreement to enable new Certificates to be issued to the
purchaser in such denominations as it shall request.  All charges and expenses
in connection with the issuance of any such new Certificates shall be borne by
the purchaser thereof.

                 As used in this Section 6.01, the terms "Class A
Certificateholder", "Class A Trust", "Class A Certificate", "Class A Trustee",
"Class B Certificate", "Class B Certificateholder", "Class B Trust", "Class B
Trustee", "Class D Certificateholder" and "Class D Trust", shall have the
respective meanings assigned to such terms in the Intercreditor Agreement.

                 Section 6.02.  Incidents of Sale of Equipment Notes.  Upon any
sale of all or any part of the Equipment Notes held in the Trust made either
under the power of sale given under this Agreement or otherwise for the
enforcement of this Agreement, the following shall be applicable:

                 (a)      Certificateholders and Trustee May Purchase Equipment
         Notes.  Any Certificateholder, the Trustee in its individual or any
         other capacity or any other

         Person may bid for and purchase any of the Equipment Notes held in the
         Trust, and upon compliance with the terms of sale, may hold, retain,
         possess and dispose of such Equipment Notes in their own absolute
         right without further accountability.

                 (b)      Receipt of Trustee Shall Discharge Purchaser.  The
         receipt of the Trustee making such sale shall be a sufficient
         discharge to any purchaser for his purchase money, and, after paying
         such purchase money and receiving such receipt, such purchaser or its
         personal representative or assigns shall not be obliged to see to the
         application of such purchase money, or be in any way answerable for
         any loss, misapplication or nonapplication thereof.

                 (c)      Application of Moneys Received upon Sale.  Any moneys
         collected by the Trustee upon any sale made either under the power of
         sale given by this Agreement or otherwise for the enforcement of this
         Agreement shall be applied as provided in Section 4.02.

                 Section 6.03.  Judicial Proceedings Instituted by Trustee;
Trustee May Bring Suit.  If there shall be a failure to make payment of the
principal of, premium, if any, or interest on any Equipment Note held in the
Trust, or if there shall be any failure to pay Rent (as defined in the relevant
Lease) under any Lease when due and payable, then the Trustee, in, its own name
and as trustee of an express trust, as holder of such Equipment Notes, to the
extent permitted by and in accordance with the terms of any related
Intercreditor Agreement and any related Note Documents (subject to rights of
the applicable Owner Trustee or Owner Participant to cure any such failure to
pay principal of, premium, if any, or interest on any Equipment Note or to pay
Rent under any Lease in accordance with the applicable Indenture), shall be
entitled and empowered to institute any suits, actions or proceedings at law,
in equity or otherwise, for the collection of the sums so due and unpaid on
such Equipment Notes or under such Lease and may prosecute any such claim or
proceeding to judgment or final decree with respect to the whole amount of any
such sums so due and unpaid.

                 Section 6.04.  Control by Certificateholders.  Subject to
Section 6.03 and the Intercreditor Agreement, the Certificateholders holding
Certificates evidencing Fractional Undivided Interests aggregating not less
than a majority in interest in the related Trust shall have the right to direct
the time, method and place of conducting any proceeding for any remedy
available to the Trustee with respect to the Trust or pursuant to the terms of
the Intercreditor Agreement, or exercising any trust or power conferred on the
Trustee under this Agreement or the Intercreditor Agreement, including any
right of the Trustee as Controlling Party under the Intercreditor Agreement or
as holder of the Equipment Notes held in the related Trust; provided, however,
that

                                       40

                 (a)      such Direction shall not in the opinion of the
         Trustee be in conflict with any rule of law or with this Agreement and
         would not involve the Trustee in personal liability or expense,

                 (b)      the Trustee shall not determine that the action so
         directed would be unjustly prejudicial to the Certificateholders not
         taking part in such Direction, and

                 (c)      the Trustee may take any other action deemed proper
         by the Trustee which is not inconsistent with such Direction.

                 Section 6.05.  Waiver of Past Defaults.  Subject to any
related Intercreditor Agreement, the Certificateholders holding Certificates of
a series evidencing Fractional Undivided Interests aggregating not less than a
majority in interest in the Trust (i) may on behalf of all of the
Certificateholders waive any past Event of Default hereunder and its
consequences or (ii) if the Trustee is the Controlling Party, may direct the
Trustee to instruct the applicable Loan Trustee to waive any past Indenture
Event of Default under any related Indenture and its consequences, and thereby
annul any Direction given by such Certificateholders or the Trustee to such
Loan Trustee with respect thereto, except a default:

                 (a)      in the deposit of any Scheduled Payment or Special
         Payment under Section 4.01 or in the distribution of any payment under
         Section 4.02 on the Certificates, or

                 (b)      in the payment of the principal of (premium, if any)
         or interest on the Equipment Notes held in the Trust, or

                 (c)      in respect of a covenant or provision hereof which
         under Article IX hereof cannot be modified or amended without the
         consent of each Certificateholder holding an Outstanding Certificate
         of a series affected thereby.

Upon any such waiver, such default shall cease to exist with respect to the
Certificates and any Event of Default arising therefrom shall be deemed to have
been cured for every purpose and any direction given by the Trustee on behalf
of the Certificateholders to the relevant Loan Trustee shall be annulled with
respect thereto; but no such waiver shall extend to any subsequent or other
default or Event of Default or impair any right consequent thereon.  Upon any
such waiver, the Trustee shall vote the Equipment Notes issued under the
relevant Indenture to waive the corresponding Indenture Event of Default.

                 Section 6.06.  Right of Certificateholders to Receive Payments
Not to Be Impaired.  Anything in this Agreement to the contrary
notwithstanding, including, without limitation, Section 6.07 hereof, but
subject to the Intercreditor Agreement, the right of any Certificateholder to
receive distributions of payments required pursuant to Section 4.02
<PAGE>   47
                                       41

hereof on the applicable Certificates when due, or to institute suit for the
enforcement of any such payment on or after the applicable Regular Distribution
Date or Special Distribution Date, shall not be impaired or affected without
the consent of such Certificateholder.

                 Section 6.07.  Certificateholders May Not Bring Suit Except
Under Certain Conditions.  A Certificateholder shall not have the right to
institute any suit, action or proceeding at law or in equity or otherwise with
respect to this Agreement, for the appointment of a receiver or for the
enforcement of any other remedy under this Agreement, unless:

                 (a)      such Certificateholder previously shall have given
         written notice to the Trustee of a continuing Event of Default;

                 (b)      Certificateholders holding Certificates evidencing
         Fractional Undivided Interests aggregating not less than 25% of the
         related Trust shall have requested the Trustee in writing to institute
         such action, suit or proceeding and shall have offered to the Trustee
         indemnity as provided in Section 7.03(e);

                 (c)      the Trustee shall have refused or neglected to
         institute any such action, suit or proceeding for 60 days after
         receipt of such notice, request and offer of indemnity; and

                 (d)      no direction inconsistent with such written request
         shall have been given to the Trustee during such 60-day period by
         Certificateholders holding Certificates evidencing Fractional
         Undivided Interests aggregating not less than a majority in interest
         in the Trust.

                 It is understood and intended that no one or more of the
Certificateholders shall have any right in any manner whatsoever hereunder or
under the related Trust Supplement or under the Certificates to (i) surrender,
impair, waive, affect, disturb or prejudice any property in the Trust Property
of the Trust, or the lien of any related Indenture on any property subject
thereto, or the rights of the Certificateholders or the holders of the
Equipment Notes, (ii) obtain or seek to obtain priority over or preference with
respect to any other such Certificateholder or (iii) enforce any right under
this Agreement, except in the manner herein provided and for the equal, ratable
and common benefit of all the Certificateholders subject to the provisions of
this Agreement.

                 Section 6.08.  Remedies Cumulative.  Every remedy given
hereunder to the Trustee or to any of the Certificateholders shall not be
exclusive of any other remedy or remedies, and every such remedy shall be
cumulative and in addition to every other remedy given hereunder or now or
hereafter given by statute, law, equity or otherwise.

                 Section 6.09.  Undertaking for Costs.  In any suit for the
enforcement of any right or remedy under this Agreement, or in any suit against
the Trustee for any action taken, suffered or omitted by it as Trustee, a court
may require any party litigant in such suit to file an undertaking to pay the
costs of such suit, and may assess costs against any such party litigant, in
the manner and to the extent provided in the Trust Indenture Act; provided,
however, that neither this Section 6.09 nor the Trust Indenture Act shall be
deemed to authorize any court to require such an undertaking or to make such an
assessment in any suit instituted by the Company.


                                  ARTICLE VII

                                  THE TRUSTEE

                 Section 7.01.  Certain Duties and Responsibilities.  (a)
Except during the continuance of an Event of Default in respect of a Trust, the
Trustee undertakes to perform such duties in respect of the Trust as are
specifically set forth in this Agreement, and no implied covenants or
obligations shall be read into this Agreement against the Trustee.

                 (b)      In case an Event of Default in respect of a Trust has
occurred and is continuing, the Trustee shall exercise such of the rights and
powers vested in it by this Agreement in respect of the Trust, and use the same
degree of care and skill in their exercise, as a prudent man would exercise or
use under the circumstances in the conduct of his own affairs.

                 (c)      No provision of this Agreement 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

                 (i)      this Subsection shall not be construed to limit the
         effect of Subsection (a) of this Section 7.01; and

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

                 (d)      Whether or not herein expressly so provided, every
provision of this Agreement relating to the conduct or affecting the liability
of or affording protection to the Trustee shall be subject to the provisions of
this Section 7.01.

                 Section 7.02.  Notice of Defaults.  As promptly as practicable
after, and in any event within 90 days after, the occurrence of any default (as
such term is defined below)
<PAGE>   49
                                       43

hereunder known to the Trustee, the Trustee shall transmit by mail to the
Company, any Owner Trustees, the Owner Participants, the Loan Trustees and the
Certificateholders holding Certificates in accordance with Section 313(c) of
the Trust Indenture Act, notice of such default hereunder known to the Trustee,
unless such default shall have been cured or waived; provided, however, that,
except in the case of a default in the payment of the principal, premium, if
any, or interest on any Equipment 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 shall determine that the withholding of such notice is in
the interests of the Certificateholders.  For the purpose of this Section 7.02
in respect of any Trust, the term "default" means any event that is, or after
notice or lapse of time or both would become, an Event of Default in respect of
that Trust.

                 Section 7.03.  Certain Rights of Trustee.  Subject to the
provisions of Section 315 of the Trust Indenture Act:

                 (a)      the Trustee may rely and shall be protected in acting
         or refraining from acting in reliance upon any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture or other paper or document
         believed by it to be genuine and to have been signed or presented by
         the proper party or parties;

                 (b)      any request or direction of the Company mentioned
         herein shall be sufficiently evidenced by a Request;

                 (c)      whenever in the administration of this Agreement or
         the Intercreditor Agreement, 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 Officer's Certificate of the Company, any Owner
         Trustee or any Loan Trustee;

                 (d)      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;

                 (e)      the Trustee shall be under no obligation to exercise
         any of the rights or powers vested in it by this Agreement or the
         Intercreditor Agreement at the Direction of any of the
         Certificateholders pursuant to this Agreement or the Intercreditor
         Agreement, unless the Certificateholders shall have offered to the
         Trustee reasonable
<PAGE>   50
                                       44

         security or indemnity against the cost, expenses and liabilities which
         might be incurred by it in compliance with such Direction;

                 (f)      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 or other paper or document;

                 (g)      the Trustee may execute any of the trusts or powers
         under this Agreement or the Intercreditor Agreement or perform any
         duties under this Agreement or the Intercreditor Agreement 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 under this Agreement
         or the Intercreditor Agreement;

                 (h)      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 Certificateholders holding Certificates
         evidencing Fractional Undivided Interests aggregating not less than a
         majority in interest in the Trust relating to the time, method and
         place of conducting any proceeding for any remedy available to the
         Trustee, or exercising any trust or power conferred upon the Trustee,
         under this Agreement or the Intercreditor Agreement; and

                 (i)      the Trustee shall not be required to expend or risk
         its own funds in the performance of any of its duties under this
         Agreement, 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 is not reasonably
         assured to it.

                 Section 7.04.  Not Responsible for Recitals or Issuance of
Certificates.  The recitals contained herein and in the Certificates, except
the certificates of authentication, shall not be taken as the statements of the
Trustee, and the Trustee assumes no responsibility for their correctness.
Subject to Section 7.15, the Trustee makes no representations as to the
validity or sufficiency of this Agreement, any Equipment Notes, the
Intercreditor Agreement, the Deposit Agreement, the Escrow Agreement, the
Certificates, or any Note Documents, except that the Trustee hereby represents
and warrants that this Agreement has been, and the Registration Rights
Agreement, each Certificate, the Note Purchase Agreement, the Escrow Agreement
and the Intercreditor Agreement will be, executed and delivered by one of its
officers who is duly authorized to execute and deliver such document on its
behalf.

                 Section 7.05.  May Hold Certificates.  The Trustee, any Paying
Agent, Registrar or any of their Affiliates or any other agent, in their
respective individual or any other capacity, may become the owner or pledgee of
Certificates and, subject to Sections
<PAGE>   51
                                       45

310(b) and 311 of the Trust Indenture Act, if applicable, may otherwise deal
with the Company, any Owner Trustees or the Loan Trustees with the same rights
it would have if it were not Trustee, Paying Agent, Registrar or such other
agent.

                 Section 7.06.  Money Held in Trust.  Money held by the Trustee
or the Paying Agent in trust under this Agreement need not be segregated from
other funds except to the extent required herein or by law and neither the
Trustee nor the Paying Agent shall have any liability for interest upon any
such moneys except as provided for herein.

                 Section 7.07.  Compensation and Reimbursement.  The Company
agrees:

                 (a)      to pay, or cause to be paid, to the Trustee from time
         to time  reasonable compensation for all services rendered by it
         hereunder (which compensation shall not be limited by any provision of
         law in regard to the compensation of a trustee of an express trust);
         and

                 (b)      to reimburse, or cause to be reimbursed, the Trustee
         upon its request for all reasonable out- of-pocket expenses,
         disbursements and advances incurred or made by the Trustee in
         accordance with any provision of this Agreement or the Intercreditor
         Agreement (including the reasonable compensation and the expenses and
         disbursements of its agents and counsel), except any such expense,
         disbursement or advance as may be attributable to its negligence,
         willful misconduct or bad faith or as may be incurred due to the
         Trustee's breach of its representations and warranties set forth in
         Section 7.15; and

                 (c)      to indemnify the Trustee with respect to the
         Certificates, pursuant to Section 8.1 of the Owned Aircraft
         Participation Agreements and Section 9.1 of the Leased Aircraft
         Participation Agreements, as the case may be.

                 The Trustee shall be entitled to reimbursement from, and shall
have a lien prior to the Certificates upon, all property and funds held or
collected by the Trustee in its capacity as Trustee for any tax incurred
without negligence, bad faith or willful misconduct, on its part, arising out
of or in connection with the acceptance or administration of the Trust (other
than any tax attributable to the Trustee's compensation for serving as such),
including any costs and expenses incurred in contesting the imposition of any
such tax.  The Trustee shall notify the Company of any claim for any tax for
which it may seek reimbursement.  If the Trustee reimburses itself from the
Trust Property of such Trust for any such tax, it will mail a brief report
within 30 days setting forth the amount of such tax and the circumstances
thereof to all Certificateholders as their names and addresses appear in the
Register.

                 Section 7.08.  Corporate Trustee Required; Eligibility.  The
Trust shall at all times have a Trustee which shall be eligible to act as a
trustee under Section 310(a) of the
<PAGE>   52
                                       46

Trust Indenture Act and shall have a combined capital and surplus of at least
$75,000,000 (or a combined capital and surplus in excess of $5,000,000 and the
obligations of which, whether now in existence or hereafter incurred, are fully
and unconditionally guaranteed by a corporation organized and doing business
under the laws of the United States, any state or territory thereof or of the
District of Columbia and having a combined capital and surplus of at least
$75,000,000).  If such corporation publishes reports of conditions at least
annually, pursuant to law or to the requirements of federal, state, territorial
or District of Columbia supervising or examining authority, then for the
purposes of this Section 7.08 the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of conditions so published.

                 In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 7.08 to act as Trustee of the
Trust, the Trustee shall resign immediately as Trustee of the Trust in the
manner and with the effect specified in Section 7.09.

                 Section 7.09.  Resignation and Removal; Appointment of
Successor.  (a)  No resignation or removal of the Trustee and no appointment of
a successor Trustee of the Trust pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee under
Section 7.10.

                 (b)      The Trustee may resign at any time as Trustee of the
Trust by giving prior written notice thereof to the Company, the Authorized
Agents, the Owner Trustees and the Loan Trustees.  If an instrument of
acceptance by a successor Trustee shall not have been delivered to the Company,
the Owner Trustees and the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

                 (c)      The Trustee may be removed at any time by Direction
of the Certificateholders holding Certificates evidencing Fractional Undivided
Interests aggregating not less than a majority in interest in such Trust
delivered to the Trustee and to the Company, the Owner Trustees and the Loan
Trustees.

                 (d)      If at any time in respect of the Trust:

                 (i)      the Trustee shall fail to comply with Section 310 of
         the Trust Indenture Act, if applicable, after written request therefor
         by the Company or by any Certificateholder who has been a bona fide
         Certificateholder for at least six months; or
<PAGE>   53
                                       47

                 (ii)     the Trustee shall cease to be eligible under Section
         7.08 and shall fail to resign after written request therefor by the
         Company or by any such Certificateholder; or

                 (iii)    the Trustee shall become incapable of acting or shall
         be adjudged a bankrupt or insolvent, or a receiver of the Trustee or
         of its property shall be appointed or any public officer shall take
         charge or control of the Trustee or of its property or affairs for the
         purpose of rehabilitation, conservation or liquidation;

then, in any case, (i) the Company may remove the Trustee or (ii) any
Certificateholder who has been a bona fide Certificateholder for at least six
months may, on behalf of itself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee of the Trust.

                 (e)      If a Responsible Officer of the Trustee shall obtain
actual knowledge of an Avoidable Tax (as defined below) in respect of any Trust
which has been or is likely to be asserted, the Trustee shall promptly notify
the Company and shall, within 30 days of such notification, resign as Trustee
of such Trust hereunder unless within such 30-day period the Trustee shall have
received notice that the Company has agreed to pay such tax.  The Company shall
promptly appoint a successor Trustee of such Trust in a jurisdiction where
there are no Avoidable Taxes.  As used herein, an "Avoidable Tax" in respect of
such Trust means a state or local tax:  (i) upon (w) such Trust, (x) such Trust
Property, (y) Certificateholders of the Trust or (z) the Trustee for which the
Trustee is entitled to seek reimbursement from the Trust Property of such
Trust, and (ii) which would be avoided if the Trustee were located in another
state, or jurisdiction within a state, within the United States of America.  A
tax shall not be an Avoidable Tax in respect of any Trust if the Company or any
Owner Trustee shall agree to pay, and shall pay, such tax.

                 (f)      If the Trustee shall resign, be removed or become
incapable of acting as Trustee of the Trust or if a vacancy shall occur in the
office of the Trustee of the Trust for any cause, the Company shall promptly
appoint a successor Trustee.  If, within one year after such resignation,
removal or incapability, or other occurrence of such vacancy, a successor
Trustee shall be appointed by Direction of the Certificateholders holding
Certificates evidencing Fractional Undivided Interests aggregating not less
than a majority in interest in such Trust delivered to the Company, the Owner
Trustees, the Loan Trustee and the retiring Trustee, then the successor Trustee
so appointed shall, with the approval of the Company of such appointment, which
approval shall not be unreasonably withheld, forthwith upon its acceptance of
such appointment, become the successor Trustee and supersede the successor
Trustee appointed as provided above.  If no successor Trustee shall have been
so appointed as provided above and accepted appointment in the manner
hereinafter provided, the resigning Trustee or any Certificateholder who has
been a bona fide Certificateholder of the related series for at least six
months may, on behalf of himself and all others similarly
<PAGE>   54
                                       48

situated, petition any court of competent jurisdiction for the appointment of a
successor Trustee.

                 (g)      The successor Trustee shall give notice of the
resignation and removal of the Trustee and appointment of the successor Trustee
by mailing written notice of such event by first-class mail, postage prepaid,
to the Certificateholders as their names and addresses appear in the Register.
Each notice shall include the name of such successor Trustee and the address of
its Corporate Trust Office.

                 Section 7.10.  Acceptance of Appointment by Successor.  Every
successor Trustee appointed hereunder shall execute and deliver to the Company
and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on request of the Company or the successor
Trustee, such retiring Trustee shall execute and deliver an instrument
transferring to such successor Trustee all such rights, powers and trusts of
the retiring Trustee and shall duly assign, transfer and deliver to such
successor Trustee all Trust Property held by such retiring Trustee, subject
nevertheless to its lien, if any, provided for in Section 7.07.  Upon request
of any such successor Trustee, the Company, the retiring Trustee and such
successor Trustee shall execute and deliver any and all instruments containing
such provisions as shall be necessary or desirable to transfer and confirm to,
and for more fully and certainly vesting in, such successor Trustee all such
rights, powers and trusts.

                 No institution shall accept its appointment as a Trustee
hereunder unless at the time of such acceptance such institution shall be
qualified and eligible under this Article VII.

                 Section 7.11.  Merger, Conversion, Consolidation or Succession
to Business.  Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder;
provided, however, that such corporation shall be otherwise qualified and
eligible under this Article VII, without the execution or filing of any paper
or any further act on the part of any of the parties hereto.  In case any
Certificates shall have been executed or authenticated, but not delivered, by
the Trustee then in office, any successor by merger, conversion or
consolidation to such authenticating Trustee may adopt such execution or
authentication and deliver the Certificates so executed or authenticated with
the same effect as if such successor Trustee had itself executed or
authenticated such Certificates.

                 Section 7.12.  Maintenance of Agencies.  (a)  With respect to
each series of Certificates, there shall at all times be maintained an office
or agency in the location set forth
<PAGE>   55
                                       49

in Section 12.04 where Certificates may be presented or surrendered for
registration of transfer or for exchange, and for payment thereof, and where
notices and demands, to or upon the Trustee in respect of such Certificates or
this Agreement may be served; provided, however, that, if it shall be necessary
that the Trustee maintain an office or agency in another location with respect
to the Certificates (e.g., the Certificates shall be represented by Definitive
Certificates and shall be listed on a national securities exchange), the
Trustee will make all reasonable efforts to establish such an office or agency.
Written notice of the location of each such other office or agency and of any
change of location thereof shall be given by the Trustee to the Company, any
Owner Trustees, the Loan Trustees (in the case of any Owner Trustee or Loan
Trustee, at its address specified in the Note Documents or such other address
as may be notified to the Trustee) and the Certificateholders.  In the event
that no such office or agency shall be maintained or no such notice of location
or of change of location shall be given, presentations and demands may be made
and notices may be served at the Corporate Trust Office of the Trustee.

                 (b)      There shall at all times be a Registrar and a Paying
Agent hereunder with respect to the Certificates.  Each such Authorized Agent
shall be a bank or trust company, shall be a corporation organized and doing
business under the laws of the United States or any state, with a combined
capital and surplus of at least $75,000,000, or a corporation having a combined
capital and surplus in excess of $5,000,000, the obligations of which are
guaranteed by a corporation organized and doing business under the laws of the
United States or any state, with a combined capital and surplus of at least
$75,000,000, and shall be authorized under such laws to exercise corporate
trust powers, subject to supervision by federal or state authorities.  The
Trustee shall initially be the Paying Agent and, as provided in Section 3.04,
Registrar hereunder with respect to the Certificates.  Each Registrar shall
furnish to the Trustee, at stated intervals of not more than six months, and at
such other times as the Trustee may request in writing, a copy of the Register
maintained by such Registrar.

                 (c)      Any corporation into which any Authorized Agent may
be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, consolidation or conversion to which any Authorized
Agent shall be a party, or any corporation succeeding to the corporate trust
business of any Authorized Agent, shall be the successor of such Authorized
Agent, if such successor corporation is otherwise eligible under this Section
7.12, without the execution or filing of any paper or any further act on the
part of the parties hereto or such Authorized Agent or such successor
corporation.

                 (d)      Any Authorized Agent may at any time resign by giving
written notice of resignation to the Trustee, the Company, any Owner Trustees
and the Loan Trustees.  The Company may, and at the request of the Trustee
shall, at any time terminate the agency of any Authorized Agent by giving
written notice of termination to such Authorized Agent and to the Trustee.
Upon the resignation or termination of an Authorized Agent or in case at any
<PAGE>   56
                                       50

time any such Authorized Agent shall cease to be eligible under this Section
7.12 (when, in either case, no other Authorized Agent performing the functions
of such Authorized Agent shall have been appointed), the Company shall promptly
appoint one or more qualified successor Authorized Agents, reasonably
satisfactory to the Trustee, to perform the functions of the Authorized Agent
which has resigned or whose agency has been terminated or who shall have ceased
to be eligible under this Section 7.12.  The Company shall give written notice
of any such appointment made by it to the Trustee, any Owner Trustees and the
Loan Trustees; and in each case the Trustee shall mail notice of such
appointment to all Certificateholders as their names and addresses appear on
the Register for such series.

                 (e)      The Company agrees to pay, or cause to be paid, from
time to time to each Authorized Agent reasonable compensation for its services
and to reimburse it for its reasonable expenses.

                 Section 7.13.  Money for Certificate Payments to Be Held in
Trust.  All moneys deposited with any Paying Agent for the purpose of any
payment on Certificates shall be deposited and held in trust for the benefit of
the Certificateholders entitled to such payment, subject to the provisions of
this Section 7.13. Moneys so deposited and held in trust shall constitute a
separate trust fund for the benefit of the Certificateholders with respect to
which such money was deposited.

                 The Trustee may at any time, for the purpose of obtaining the
satisfaction and discharge of this Agreement or for any other purpose, direct
any Paying Agent to pay to the Trustee all sums held in trust by such Paying
Agent, such sums to be held by the Trustee upon the same trusts as those upon
which such sums were held by such Paying Agent; and, upon such payment by any
Paying Agent to the Trustee, such Paying Agent shall be released from all
further liability with respect to such money.

                 Section 7.14.  Registration of Equipment Notes in Trustee's
Name.  Subject to the provisions of any Intercreditor Agreement, the Trustee
agrees that all Equipment Notes to be purchased by any Trust and Permitted
Investments, if any, shall be issued in the name of the Trustee as trustee for
the applicable Trust or its nominee and held by the Trustee in trust for the
benefit of the Certificateholders, or, if not so held, the Trustee or its
nominee shall be reflected as the owner of such Equipment Notes or Permitted
Investments, as the case may be, in the register of the issuer of such
Equipment Notes or Permitted Investments, as the case may be.

                 Section 7.15.  Representations and Warranties of Trustee.  The
Trustee hereby represents and warrants that:

                 (a)      the Trustee is a Delaware banking corporation

         indenture, contract, agreement or other undertaking to which it is a
         party, which violation, default or lien could reasonably be expected
         to have an adverse effect on the Trustee's performance or ability to
         perform its duties hereunder or thereunder or on the transactions
         contemplated herein or therein;

                 (d)      the execution, delivery and performance by the

present or future taxes or similar charges are required to be withheld with
respect to any amounts payable in respect of the Certificates, to withhold such
amounts and timely pay the same to the appropriate authority in the name of and
on behalf of the Certificateholders, that it will file any necessary

Certificateholder appropriate documentation showing the payment thereof,
together with such additional documentary evidence as such Certificateholders

respect to the Trust Property of such Trust which is attributable to the
Trustee either (i) in its individual capacity and which is unrelated to the
transactions contemplated by this Agreement, the Intercreditor Agreement, the
Note Purchase Agreement or the Note Documents or (ii) as Trustee hereunder or

provided, however, that no such supplemental agreement shall adversely affect
the status of any Trust as a grantor trust under Subpart E, Part I of

purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Agreement, the Intercreditor Agreement, the

modifying in any manner the rights and obligations of such Certificateholders
under this Agreement, the Intercreditor Agreement, the Escrow Agreement, the

                                       57

         provisions of this Agreement or certain defaults hereunder and their
         consequences) provided for in this Agreement; or

                 (e)      modify any of the provisions of this Section 9.02 or
         Section 6.05, except to increase any such percentage or to provide
         that certain other provisions of this Agreement cannot be modified or
         waived without the consent of the Certificateholder of each
         Certificate affected thereby; or

         trust under Subpart E, Part I of Subchapter J of Chapter 1 of Subtitle

         income tax purposes.

                 It shall not be necessary for any Direction of such
Certificateholders under this Section 9.02 to approve the particular form of
any proposed supplemental agreement, but it shall be sufficient if such
Direction shall approve the substance thereof.

                 Section 9.03.  Documents Affecting Immunity or Indemnity.  If
in the opinion of the Trustee any document required to be executed by it
pursuant to the terms of Section 9.01 or 9.02 affects any interest, right,

Trust Supplement, the Trustee may in its discretion decline to execute such
document.

                 Section 9.04.  Execution of Supplemental Agreements.  In
executing, or accepting the additional trusts created by, any supplemental
agreement permitted by this Article or the modifications thereby of the trusts
created by this Agreement, the Trustee shall be entitled to receive, and shall
be fully protected in relying upon, an Opinion of Counsel stating that the
execution of such supplemental agreement is authorized or permitted by this
Agreement.

                 Section 9.05.  Effect of Supplemental Agreements.  Upon the
execution of any agreement supplemental to this Agreement under this Article,
this Agreement shall be modified in accordance therewith, and such supplemental
agreement shall form a part of this Agreement for all purposes; and every

                                   ARTICLE X

                   AMENDMENTS TO INDENTURE AND NOTE DOCUMENTS

                 Section 10.01.  Amendments and Supplements to Indenture and
Other Note Documents.  In the event that the Trustee, as holder (or beneficial
owner through the Subordination Agent) of any Equipment Notes (or as a
prospective purchaser of any Postponed Notes) in trust for the benefit of the
Certificateholders or as Controlling Party under an Intercreditor Agreement,
receives (directly or indirectly through the Subordination Agent) a request for
a consent to any amendment, modification, waiver or supplement under any
Indenture, other Note Document or any other related document, which request
would require the consent of Certificateholders under Section 9.02 hereof, the
Trustee shall forthwith send a notice of such proposed amendment, modification,
waiver or supplement to each Certificateholder registered on the Register as of
the date of such notice.  The Trustee shall request from the Certificateholders
a Direction as to (a) whether or not to take or refrain from taking (or direct
the Subordination Agent to take or refrain from taking) any action which a
holder of (or, with respect to Postponed Notes, a prospective purchaser of)
such Equipment Note or a Controlling Party has the option to direct, (b)
whether or not to give or execute (or direct the Subordination Agent to give or
execute) any waivers, consents, amendments, modifications or supplements as a
holder of (or, with respect to Postponed Notes, a prospective purchaser of)
such Equipment Note or as Controlling Party and (c) how to vote (or direct the
Subordination Agent to vote) any Equipment Note (or, with respect to a
Postponed Note, its commitment to acquire such Postponed Note) if a vote has
been called for with respect thereto.  Provided such a request for
Certificateholder Direction shall have been made, in directing any action or
casting any vote or giving any consent as the holder of any Equipment Note (or
in directing the Subordination Agent in any of the foregoing), (i) other than
as Controlling Party, the Trustee shall vote for or give consent to any such
action with respect to such Equipment Note (or Postponed Note) in the same
proportion as that of (A) the aggregate face amounts of all Certificates
actually voted in favor of or for giving consent to such action by such
Direction of Certificateholders to (B) the aggregate face amount of all
Outstanding Certificates and (ii) as Controlling Party, the Trustee shall vote
as directed in such Certificateholder Direction by the Certificateholders
evidencing a Fractional Undivided Interest aggregating not less than a majority
in interest in the Trust.  For purposes of the immediately preceding sentence,
a Certificate shall have been "actually voted" if the Holder of such
Certificate has delivered to the Trustee an instrument evidencing such Holder's
consent to such Direction prior to one Business Day before the Trustee directs
such action or casts such vote or gives such consent.  Notwithstanding the
foregoing, but
<PAGE>   65
                                       59

subject to Section 6.04 and any Intercreditor Agreement, the Trustee may, with
respect to the Certificates, in its own discretion and at its own direction,
consent and notify the relevant Loan Trustee of such consent (or direct the
Subordination Agent to consent and notify the Loan Trustee of such consent) to
any amendment, modification, waiver or supplement under any related Indenture
or any other related Note Document if an Event of Default hereunder shall have
occurred and be continuing or if such amendment, modification, waiver or
supplement will not materially adversely affect the interests of the
Certificateholders.

                 the parties thereto in accordance with the terms of this
                 Agreement and the Related Pass Through Trust Agreement, the
                 Assignment and Assumption Agreement will constitute the valid
                 and binding obligation of each of the parties thereto
                 enforceable against each such party in accordance with its
                 terms;

                          (b)     upon the execution and delivery of the
                 Assignment and Assumption Agreement in accordance with the

                 registered as an investment company under the Investment
                 Company Act of 1940, as amended;
                          (d)     the Related Pass Through Trust Agreement
                 constitutes the valid and binding obligation of the Company
                 enforceable against the Company in accordance with its terms;

                 Assignment and Assumption Agreement in accordance with the
                 terms of this Agreement and the Related Pass Through Trust
                 Agreement, nor the consummation by the parties thereto of the
                 transactions contemplated to be consummated thereunder on the
                 date thereof, will violate any law or governmental rule or
                 regulation of the State of New York or the United States of
                 America known to such counsel to be applicable to the
                 transactions contemplated by the Assignment and Assumption
                 Agreement.

         the Related Trustee with the Office of the Superintendent, State of
         New York Banking Department for the qualification of the Related
         Trustee under Section 131(3) of the New York Banking Law.

Upon the execution of the Assignment and Assumption Agreement by the parties
thereto, the Trust shall be terminated, the Certificateholders shall receive
beneficial interests in the Related Trust in exchange for their interests in
the Trust equal to their respective beneficial interests in the Trust, and the
Outstanding Certificates representing Fractional Undivided Interests in the

Through Trust Agreement, without further signature or action of any party or
<PAGE>   67
                                       61

Certificateholder, to be certificates representing the same fractional
undivided interests in the Related Trust and its trust property.  By acceptance
of its Certificate, each Certificateholder consents to such assignment,
transfer and delivery of the Trust Property to the trustee of the Related Trust
upon the execution and delivery of the Assignment and Assumption Agreement.

                 In connection with the occurrence of the event set forth in
clause (B) above, notice of such termination, specifying the Distribution Date
upon which the Certificateholders may surrender their Certificates to the
Trustee for payment of the final distribution and cancellation, shall be mailed
promptly by the Trustee to Certificateholders not earlier than the 60th day and
not later than the 15th day next preceding such final Distribution Date
specifying (A) the Distribution Date upon which the proposed final payment of
the Certificates will be made upon presentation and surrender of Certificates
at the office or agency of the Trustee therein specified, (B) the amount of any
such proposed final payment, and (c) that the Record Date otherwise applicable
to such Distribution Date is not applicable, payments being made only upon
presentation and surrender of the Certificates at the office or agency of the
Trustee therein specified.  The Trustee shall give such notice to the Registrar
at the time such notice is given to Certificateholders.  Upon presentation and
surrender of the Certificates in accordance with such notice, the Trustee shall
cause to be distributed to Certificateholders such final payments.

                 In the event that all of the Certificateholders shall not
surrender their Certificates for cancellation within six months after the date
specified in the above-mentioned written notice, the Trustee shall give a
second written notice to the remaining Certificateholders to surrender their
Certificates for cancellation and receive the final distribution with respect
thereto.  No additional interest shall accrue on the Certificates after the
Distribution Date specified in the first written notice.  In the event that any
money held by the Trustee for the payment of distributions on the Certificates
shall remain unclaimed for two years (or such lesser time as the Trustee shall
be satisfied, after sixty days' notice from the Company, is one month prior to
the escheat period provided under applicable law) after the final distribution
date with respect thereto, the Trustee shall pay to each Loan Trustee the
appropriate amount of money relating to such Loan Trustee and shall give
written notice thereof to the related Owner Trustees, the Owner Participants
and the Company.

                 The Certificates do not represent a direct obligation of, or
an obligation guaranteed by, or an interest in, the Company or the Trustee or
any of their affiliates.  The Certificates are limited in right of payment, all
as more specifically set forth on the face hereof and in the Agreement.  All
payments or distributions made to Certificateholders under the Agreement shall
be made only from the Trust Property and only to the extent that the Trustee
shall have sufficient income or proceeds from the Trust Property to make such
payments in accordance with the terms of the Agreement.  Each Certificateholder
of this Certificate, by its acceptance hereof, agrees that it will look solely
to the income and proceeds from the Trust Property to the extent available for
distribution to such Certificateholder as provided in the Agreement.  This
Certificate does not purport to summarize the Agreement and reference is made
to the Agreement for information with respect to the interests, rights,
benefits, obligations, proceeds, and duties evidenced hereby.  A copy of the
Agreement may be examined during normal business hours at the principal office
of the Trustee, and at such other places, if any, designated by the Trustee, by
any Certificateholder upon request.

                 The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Certificateholders under the
Agreement at any time by the Company and the Trustee with the consent of the
Certificateholders holding Certificates evidencing Fractional Undivided
Interests aggregating not less than a majority in interest in the Trust.  Any
such consent by the Certificateholder of this Certificate shall be conclusive
and binding on such Certificateholder and upon all future Certificateholders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange hereof or in lieu hereof whether or not notation of such consent is
made upon this Certificate.  The Agreement also permits the amendment thereof,
in certain limited circumstances, without the consent of the Certificateholders
of any of the Certificates.

                 As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Register upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee in its capacity as
Registrar, or by any successor Registrar, in the Borough of Manhattan, the City
of New York, duly endorsed or accompanied by a written instrument of transfer
in form satisfactory to the Trustee and the Registrar duly executed by the
Certificateholder hereof or such Certificateholder's attorney duly authorized
in writing, and thereupon one or more new Certificates of authorized
denominations evidencing the same aggregate Fractional Undivided Interest in
the Trust will be issued to the designated transferee or transferees.

                                      A-9

                 The Certificates are issuable only as registered Certificates
without coupons in minimum denominations of [$100,000]* [$1,000]** Fractional
Undivided Interest and integral multiples of $1,000 in excess thereof [except
that one Certificate may be in a denomination of less than $100,000]*.  As
provided in the Agreement and subject to certain limitations therein set forth,
the Certificates are exchangeable for new Certificates of authorized
denominations evidencing the same aggregate Fractional Undivided Interest in
the Trust, as requested by the Certificateholder surrendering the same.

                 No service charge will be made for any such registration of
transfer or exchange, but the Trustee shall require payment by the Holder of a
sum sufficient to cover any tax or governmental charge payable in connection
therewith.

                 The Trustee, the Registrar, and any agent of the Trustee or
the Registrar may treat the person in whose name this Certificate is registered
as the owner hereof for all purposes, and neither the Trustee, the Registrar,
nor any such agent shall be affected by any notice to the contrary.

                 The obligations and responsibilities created by the Agreement
and the Trust created thereby shall terminate upon the distribution to
Certificateholders of all amounts required to be distributed to them pursuant
to the Agreement and the disposition of all property held as part of the Trust
Property.

Dear Sirs:

                 In connection with our proposed purchase of $_______________
aggregate principal amount of the Certificates, we confirm that:

                 1.       We understand that any subsequent transfer of the
         Certificates is subject to certain restrictions and conditions set
         forth in the Pass Through Trust Agreement dated as of February 9, 1998
         relating to the Certificates (the "Pass Through Trust Agreement") and
         the undersigned agrees to be bound by, and not to resell, pledge or
         otherwise transfer the Certificates except in compliance with, such
         restrictions and conditions and the Securities Act of 1933, as amended
         (the "Securities Act").

                 2.       We understand that the Certificates have not been
         registered under the Securities Act, and that the Certificates may not
         be offered or sold except as permitted in the following sentence.  We
         agree, on our own behalf and on behalf of any accounts for which we
         are acting as hereinafter stated, that if we should sell any
         Certificate, we will do so only (A) in accordance with Rule 144A under
         the Securities Act to a "qualified institutional buyer" (as defined
         therein), (B) to an institutional "accredited investor" (as defined
         below) that, prior to such transfer, furnishes to you and Continental
         Airlines, Inc., a signed letter substantially in the form of this
         letter, (C) outside the United States in accordance with Rule 904 of
         Regulation S under the Securities Act, (D) pursuant to the exemption
         from registration provided by Rule 144 under the Securities Act, or
         (E) pursuant to an effective registration statement under

                                      D-2

         the Securities Act, and we further agree to provide to any person
         purchasing any of the Certificates from us a notice advising such
         purchaser that resales of the Notes are restricted as stated herein.
         We further understand that the Certificates purchased by us will bear
         a legend to the foregoing effect.

                 3.       We understand that, on any proposed resale of any
         Certificates, we will be required to furnish to you and Atlas Air,
         Inc. such certifications, legal opinions and other information as you
         and Atlas Air, Inc.  may reasonably require to confirm that the
         proposed sale complies with the foregoing restrictions.  We further
         understand that the Certificates purchased by us will bear a legend to
         the foregoing effect.

                 4.       We are an institutional "accredited investor" (as
         defined in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the
         Securities Act) and have such knowledge and experience in financial
         and business matters as to be capable of evaluating the merits and
         risks of our investment in the Certificates and we and any accounts
         for which we are acting are each able to bear the economic risk of our
         or its investment.

                 5.       We are acquiring the Certificates purchased by us for
         our own account or for one or more accounts (each of which is an
         institutional "accredited investor") as to each of which we exercise
         sole investment discretion.

                 You and Atlas Air, Inc. are entitled to rely upon this letter
and are irrevocably authorized to produce this letter or a copy hereof to any
interested party in any administrative or legal proceedings or official inquiry

action provided by this Agreement in respect of the Certificates to be given or
taken by Certificateholders (a "Direction") may be embodied in and evidenced by
one or more instruments of substantially similar tenor signed by such
Certificateholders in person or by an agent or proxy 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,
when it is hereby expressly required pursuant to this Agreement, to the Company
or any Loan Trustee.  Such instrument or instruments (and the action embodied
therein and evidenced thereby) are herein sometimes referred to as the "Act" of
the Certificateholders signing such instrument or instruments.  Proof of
execution of any such instrument or of a writing appointing any such agent or
proxy shall be sufficient for any purpose of this Trust Agreement and
conclusive in favor of the Trustee, the Company and the related Loan Trustee,
if made in the manner provided in this Section 1.04.

                 (b)      The fact and date of the execution by any Person of
any such instrument or writing may be proved by the certificate of any notary
public or other officer of any jurisdiction authorized to take acknowledgments
of deeds or administer oaths that the Person executing such instrument
acknowledged to him the execution thereof, or by an affidavit of a witness to
such execution sworn to before any such notary or such other officer, and where
such execution is by an officer of a corporation or association or a member of
a partnership, on behalf of such corporation, association or partnership, such
certificate or affidavit shall also constitute sufficient proof of his
authority.  The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other reasonable manner which the Trustee deems sufficient.

                 (c)      In determining whether the Certificateholders of the
requisite Fractional Undivided Interests of Certificates Outstanding have given
any Direction under this Agreement, Certificates owned by the Company or any
Affiliate thereof shall be disregarded and deemed not to be Outstanding for
purposes of any such determination.  In determining whether the Trustee shall
be protected in relying upon any such Direction, only Certificates which the
Trustee knows to be so owned shall be so disregarded.  Notwithstanding the
foregoing, (i) if any such Person owns 100% of the Certificates Outstanding,
such Certificates shall not be so disregarded, and (ii) if any amount of
Certificates so owned by any such Person have been pledged in good faith, such
Certificates shall not be disregarded if the pledgee establishes to the
satisfaction of the Trustee the pledgee's right so to act with respect to such
Certificates and that the pledgee is not the Company or any Affiliate thereof.

                 (d)      The Company may, at its option, by delivery of an
Officer's Certificate to the Trustee, set a record date to determine the
Certificateholders in respect of the Certificates, entitled to give any
Direction.  Notwithstanding Section 316(c) of the Trust
<PAGE>   23
                                       17

Indenture Act, such record date shall be the record date specified in such
Officer's Certificate, which shall be a date not more than 30 days prior to the
first solicitation of Certificateholders of the applicable series in connection
therewith.  If such a record date is fixed, such Direction may be given before
or after such record date, but only the Certificateholders of record of the
applicable series at the close of business on such record date shall be deemed
to be Certificateholders for the purposes of determining whether
Certificateholders of the requisite proportion of Outstanding Certificates have
authorized or agreed or consented to such Direction, and for that purpose the
Outstanding Certificates shall be computed as of such record date; provided,
however, that no such Direction by the Certificateholders on such record date
shall be deemed effective unless it shall become effective pursuant to the
provisions of this Agreement not later than one year after such record date.

                 (e)      Any Direction by the Holder of any Certificate shall
bind the Holder of every Certificate issued upon the transfer thereof or in
exchange therefor or in lieu thereof, whether or not notation of such Direction
is made upon such Certificate.

                 (f)      Except as otherwise provided in Section 1.04(c),
Certificates owned by or pledged to any Person shall have an equal and
proportionate benefit under the provisions of this Agreement, without
preference, priority or distinction as among all of the Certificates.


                                   ARTICLE II

                       ACQUISITION OF THE TRUST PROPERTY

                 Section 2.01.    Acquisition of Trust Property.  The Trustee
is hereby irrevocably authorized and directed to execute and deliver the
Assignment and Assumption Agreement on the date specified in Section 11.01 of
the Related Pass Through Trust Agreement, subject only to the satisfaction of
the conditions set forth in said Section 11.01.  This Agreement (except only
for the immediately preceding sentence hereof, which is effective upon
execution and delivery hereof) shall become effective upon the execution and
delivery of the Assignment and Assumption Agreement by the Trustee and the
Related Trustee, automatically and without any further signature or action on
the part of the Company and the Trustee, and shall thereupon constitute the
legal, valid and binding obligation of the parties hereto enforceable against
each of the parties hereto in accordance with its terms.  Upon such execution
and delivery of the Assignment and Assumption Agreement, the Related Trust
shall be terminated, the Certificateholders shall receive beneficial interests
in the Trust in exchange for their interests in the Related Trust equal to
their respective beneficial interests in the Related Trust and the
"Outstanding" (as defined in the Related Pass Through Trust Agreement) pass
through certificates representing fractional undivided interests in the Related
Trust shall be deemed for all purposes of this Agreement,
<PAGE>   24
                                       18

without further signature or action of any party or Certificateholder, to be
Certificates representing the same Fractional Undivided Interests in the Trust
and Trust Property.  By acceptance of its Certificate, each Certificateholder
consents to and ratifies such assignment, transfer and delivery of the trust
property of the Related Trust to the Trustee upon the execution and delivery of
the Assignment and Assumption Agreement.

                 Section 2.02. [Intentionally omitted]

                 Section 2.03.  Acceptance by Trustee.  The Trustee, upon the
execution and delivery of the Assignment and Assumption Agreement, acknowledges
its acceptance of all right, title and interest in and to the Trust Property
and will hold such right, title and interest for the benefit of all then
present and future Certificateholders, upon the trusts herein set forth.  By
its payment for and acceptance of each Certificate issued under the Related
Pass Through Trust Agreement and deemed issued under this Agreement, each
Holder of such Certificate as grantor of such Trust thereby joins in the
creation and declaration of such Trust.

                 Section 2.04.  Limitation of Powers.  The Trust is constituted
solely for the purpose of making the investment in the Equipment Notes, and,
except as set forth herein, the Trustee shall not be authorized or empowered to
acquire any other investments or engage in any other activities and, in
particular, the Trustee shall not be authorized or empowered to do anything
that would cause such Trust to fail to qualify as a "grantor trust" for federal
income tax purposes (including, as subject to this restriction, acquiring any
Aircraft (as defined in the respective Indentures) by bidding such Equipment
Notes or otherwise, or taking any action with respect to any such Aircraft once
acquired).


                                  ARTICLE III

                                THE CERTIFICATES

                 Section 3.01.  Title, Form, Denomination and Execution of
Certificates.  (a)  The Initial Certificates shall be known as the "8.01%
1998-1C-S Initial Pass Through Certificates" and the Exchange Certificates
shall be known as the "8.01% 1998-1C-S Exchange Pass Through Certificates", in
each case, of the Trust.  Each Certificate will represent a fractional
undivided interest in the Trust and shall be substantially in the form set
forth as Exhibit A to the Related Pass Through Trust Agreement, with such
appropriate insertions, omissions, substitutions and other variations as are
required or permitted by the Related Pass Through Trust Agreement or by this
Agreement, as the case may be, or as the Trustee may deem appropriate, to
reflect the fact that the Certificates are being issued hereunder as opposed to
under the Related Pass Through Trust Agreement and may have such letters,
numbers or other marks of identification and such legends or endorsements
<PAGE>   25
                                       19

placed thereon as may be required to comply with the rules of any securities
exchange or as may, consistently herewith, be determined by the officers
executing such Certificates, as evidenced by their execution of the
Certificates.  Any portion of the text of any Certificate may be set forth on
the reverse thereof, with an appropriate reference thereto on the face of the
Certificate.

                 (b)      The Initial Certificates shall be issued only in
fully registered form without coupons and only in denominations of $100,000 or
integral multiples of $1,000 in excess thereof, except that one Certificate may
be issued in a denomination of less than $100,000.  The Exchange Certificates
will be issued in denominations of $1,000 or integral multiples thereof.  Each
Certificate shall be dated the date of its authentication.  The aggregate
Fractional Undivided Interest of Certificates initially deemed issued hereunder
shall not at any time exceed the aggregate principal amount of "Outstanding"
pass through trust certificates representing fractional undivided interests in
the Related Trust on the Transfer Date.

                 (c)      Initial Certificates offered and sold in reliance on
Rule 144A shall be issued initially in the form of a single permanent global
Certificate in registered form, substantially in the form set forth as Exhibit
A to the Related Pass Through Trust Agreement (the "U.S. Global Certificate"),
duly executed and authenticated by the Trustee as hereinafter provided.  The
U.S. Global Certificate will be registered in the name of a nominee for the
Depositary and deposited with the Trustee, as custodian for the Depositary.
The aggregate principal amount of the U.S. Global Certificate may from time to
time be increased or decreased by adjustments made on the records of the
Depositary or its nominee, or of the Trustee, as custodian for the Depositary
or its nominee, as hereinafter provided.

                 (d)      Initial Certificates offered and sold in offshore
transactions in reliance on Regulation S shall be issued initially in the form
of a single temporary global Certificate in registered form, substantially in
the form set forth as Exhibit A to the Related Pass Through Trust Agreement
(the "Temporary Offshore Global Certificate") duly executed and authenticated
by the Trustee as hereinafter provided.  The Temporary Offshore Global
Certificates will be registered in the name of a nominee of the Depositary for
credit to the account of the Agent Members acting as depositaries for Euroclear
and Cedel and deposited with the Trustee as custodian for the Depositary.  At
any time following March 21, 1998 (the "Offshore Certificates Exchange Date"),
upon receipt by the Trustee of a certificate substantially in the form of
Exhibit B to the Related Pass Through Trust Agreement, a single permanent
global Certificate in registered form substantially in the form set forth in
Exhibit A (the "Permanent Offshore Global Certificate"; and together with the
Temporary Offshore Global Certificate, the "Offshore Global Certificates"),
duly executed and authenticated by the Trustee as hereinafter provided, shall
be registered in the name of a nominee for the Depositary and deposited with
the Trustee, as custodian for the Depositary, and the Registrar shall reflect
on its books and records the date of such transfer and a decrease in the
principal
<PAGE>   26
                                       20

amount of any Temporary Offshore Global Certificate in an amount equal to the
principal amount of the beneficial interest in such Temporary Offshore Global
Certificate transferred.  The U.S. Global Certificate and the Offshore Global
Certificates are sometimes referred to as the "Global Certificates".

                 (e)      Initial Certificates offered and sold to
Institutional Accredited Investors shall be issued in the form of permanent
certificated Certificates in registered form in substantially the form set
forth as Exhibit A to the Related Pass Through Trust Agreement (the "U.S.
Physical Certificates").  Certificates issued pursuant to Section 3.05(b) in
exchange for interests in any Offshore Global Certificate shall be in the form
of permanent certificated Certificates in registered form substantially in the
form set forth in Exhibit A (the "Offshore Physical Certificates").  The
Offshore Physical Certificates and U.S. Physical Certificates are sometimes
collectively herein referred to as the "Physical Certificates".

                 (f)      The Exchange Certificates shall be issued in the form
of one or more global Certificates substantially in the form of Exhibit A to
the Related Pass Through Trust Agreement (each, a "Global Exchange
Certificate"), except that (i) the Private Placement Legend (hereinafter
defined) shall be omitted and (ii)  such Exchange Certificates shall contain
such appropriate insertions, omissions, substitutions and other variations from
the form set forth in Exhibit A to the Related Pass Through Trust Agreement
relating to the nature of the Exchange Certificates as the Responsible Officer
of the Trustee executing such Exchange Certificates on behalf of the Trust may
determine, as evidenced by such officer's execution on behalf of the Trust of
such Exchange Certificates.  Such Global Exchange Certificates shall be in
registered form and be registered in the name of DTC and deposited with the
Trustee, at its Corporate Trust Office, as custodian for DTC.  The aggregate
principal amount of any Global Exchange Certificate may from time to time be
increased or decreased by adjustments made on the records of the Trustee, as
custodian for DTC for such Global Exchange Certificate, which adjustments shall
be conclusive as to the aggregate principal amount of any such Global Exchange
Certificate.  Subject to clause (i) and (ii)  of the first sentence of this
Section 3.01(f), the terms hereof applicable to Restricted Global Certificates
and/or Global Certificates shall apply to the Global Exchange Certificates,
mutatis mutandis.

                 (g)      The definitive Certificates shall be in registered
form and shall be typed, printed, lithographed or engraved or produced by any
combination of these methods or may be produced in any other manner, all as
determined by the officers executing such Certificates, as evidenced by their
execution of such Certificates.

                 Section 3.02.  Restrictive Legends.  (a)  Subject to Section
3.06, unless and until (i) an Initial Certificate is sold under an effective
Registration Statement or (ii) an Initial Certificate is exchanged for an
Exchange Certificate pursuant to an effective Exchange Offer Registration
Statement, in each case as provided for in the Registration Rights Agreement,
<PAGE>   27
                                       21

each Global Certificate (other than the Permanent Offshore Global Certificate)
and each U.S. Physical Certificate shall bear the following legend (the
"Private Placement Legend") on the face thereof:

                 THIS CERTIFICATE HAS NOT BEEN REGISTERED UNDER THE U.S.
         SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND
         ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR
         TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY PERSONS EXCEPT AS SET FORTH
         IN THE FOLLOWING SENTENCE.  BY ITS ACQUISITION HEREOF, THE HOLDER (1)
         REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS
         DEFINED IN RULE 144A UNDER THE SECURITIES ACT), (B) IT IS AN
         INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)(1),
         (2), (3) OR (7) OF REGULATION D UNDER THE SECURITIES ACT) (AN
         "INSTITUTIONAL ACCREDITED INVESTOR") OR (C) IT IS NOT A U.S.  PERSON
         AND IS ACQUIRING THIS CERTIFICATE IN AN OFFSHORE TRANSACTION IN
         COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT; (2) AGREES THAT
         IT WILL NOT WITHIN TWO YEARS AFTER THE LATER OF THE ORIGINAL ISSUANCE
         OF THIS CERTIFICATE OR THE LAST DATE ON WHICH THIS CERTIFICATE WAS
         HELD BY ATLAS AIR, INC., THE TRUSTEE OR ANY AFFILIATE OF ANY OF SUCH
         PERSONS RESELL OR OTHERWISE TRANSFER THIS CERTIFICATE EXCEPT (A) TO A
         QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE
         SECURITIES ACT, (B) INSIDE THE UNITED STATES TO AN INSTITUTIONAL
         ACCREDITED INVESTOR ACQUIRING $100,000 OR MORE AGGREGATE PRINCIPAL
         AMOUNT OF  SUCH CERTIFICATE THAT, PRIOR TO SUCH TRANSFER, FURNISHES TO
         THE TRUSTEE A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND
         AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THIS
         CERTIFICATE (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM THE
         TRUSTEE), (C) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN
         COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT, (D) PURSUANT TO THE
         EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES
         ACT (IF AVAILABLE) OR (E) PURSUANT TO AN EFFECTIVE REGISTRATION
         STATEMENT UNDER THE SECURITIES ACT; AND (3) AGREES THAT IT WILL
         DELIVER TO EACH PERSON TO WHOM THIS CERTIFICATE IS TRANSFERRED A
         NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.  IN CONNECTION WITH
         ANY TRANSFER OF THIS CERTIFICATE WITHIN TWO YEARS AFTER THE LATER OF
         THE ORIGINAL ISSUANCE OF THIS CERTIFICATE OR THE LAST DATE ON WHICH
         THIS CERTIFICATE WAS HELD BY ATLAS AIR,
<PAGE>   28
                                       22

         INC., THE TRUSTEE OR ANY AFFILIATE OF ANY OF SUCH PERSONS THE HOLDER
         MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF
         RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO
         THE TRUSTEE.  AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION",
         "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM BY
         REGULATION S UNDER THE SECURITIES ACT.  THE PASS THROUGH TRUST
         AGREEMENT CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO
         REGISTER ANY TRANSFER OF THIS CERTIFICATE IN VIOLATION OF THE
         FOREGOING RESTRICTIONS.

                 (b)      Each Global Certificate shall also bear the following
legend on the face thereof:

         UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE
         OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO
         THE TRUSTEE OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR
         PAYMENT, AND ANY CERTIFICATE ISSUED IN EXCHANGE FOR THIS CERTIFICATE
         IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS
         REQUESTED BY AN AUTHORIZED  REPRESENTATIVE OF DTC (AND ANY PAYMENT
         HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED
         BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER
         USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL
         INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
         HEREIN.

         TRANSFERS OF THIS GLOBAL CERTIFICATE SHALL BE LIMITED TO TRANSFERS IN
         WHOLE, BUT NOT IN PART, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF
         OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL
         CERTIFICATE SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE
         RESTRICTIONS SET FORTH IN SECTIONS 3.05 AND 3.06 OF THE PASS THROUGH
         TRUST AGREEMENT REFERRED TO HEREIN.

                 Section 3.03.  Authentication of Certificates.  (a)
[Intentionally omitted]

                 (b)      No Certificate shall be entitled to any benefit under
this Agreement or be valid or obligatory for any purpose, unless there appears
on such Certificate a certificate of authentication substantially in the form
provided for herein executed by the Related Trustee or by the Trustee by the
manual signature of one of its authorized signatories, and
<PAGE>   29
                                       23

such certificate upon any Certificate shall be conclusive evidence, and the
only evidence, that such Certificate has been duly authenticated and delivered
hereunder.

                 Section 3.04.  Transfer and Exchange.  The Trustee shall cause
to be kept at the office or agency to be maintained by it in accordance with
the provisions of Section 7.12 of this Agreement a register (the "Register")
for the Certificates in which, subject to such reasonable regulations as it may
prescribe, the Trustee shall provide for the registration of the Certificates
and of transfers and exchanges of the Certificates as herein provided.  The
Trustee shall initially be the registrar (the "Registrar") for the purpose of
registering the Certificates and transfers and exchanges of the Certificates as
herein provided.  A Certificateholder may transfer a Certificate by written
application to the Registrar stating the name of the proposed transferee and
otherwise complying with the terms of this Agreement, including providing a
written certificate or other evidence of compliance with any restrictions on
transfer.  No such transfer shall be effected until, and such transferee shall
succeed to the rights of a Certificateholder only upon, final acceptance and
registration of the transfer by the Registrar in the Register.  Prior to the
registration of any transfer by a Certificateholder as provided herein, the
Trustee shall treat the person in whose name the Certificate is registered as
the owner thereof for all purposes, and the Trustee shall not be affected by
notice to the contrary.  Furthermore, the Depositary shall, by acceptance of a
Global Certificate, agree that transfers of beneficial interests in such Global
Certificate may be effected only through a book-entry system maintained by the
Depositary (or its agent), and that ownership of a beneficial interest in the
Certificate shall be required to be reflected in a book entry.  When
Certificates are presented to the Registrar with a request to register the
transfer or to exchange them for an equal face amount of Certificates of other
authorized denominations, the Registrar shall register the transfer or make the
exchange as requested if its requirements for such transactions are met.  To
permit registrations of transfers and exchanges in accordance with the terms,
conditions and restrictions hereof, the Trustee shall execute and authenticate
Certificates at the Registrar's request.  No service charge shall be made for
any registration of transfer or exchange of the Certificates, but the Trustee
may require payment by the transferor 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 charges payable upon
exchanges pursuant to Section 3.10 or 9.07).

                 Section 3.05.  Book-Entry Provisions for U.S. Global
Certificate and Offshore Global Certificates.  (a) Members of, or participants
in, the Depositary ("Agent Members") shall have no rights under this Agreement
with respect to any Global Certificate held on their behalf by the Depositary,
or the Trustee as its custodian, and the Depositary may be treated by the
Trustee and any agent of the Trustee as the absolute owner of such Global
Certificate for all purposes whatsoever.  Notwithstanding the foregoing,
nothing herein shall prevent the Trustee or any agent of the Trustee from
giving effect to any written certification, proxy or other authorization
furnished by the Depositary or shall impair, as between the Depositary
<PAGE>   30
                                       24

and its Agent Members, the operation of customary practices governing the
exercise of the rights of a holder of any Certificate.  Upon the issuance of
any Global Certificate, the Registrar or its duly appointed agent shall record
a nominee of the Depositary as the registered holder of such Global
Certificate.

                 (b)      Transfers of any Global Certificate shall be limited
to transfers of such Global Certificate or Offshore Global Certificate in
whole, but not in part, to nominees of the Depositary, its successor or such
successor's nominees.  Beneficial interests in the U.S. Global Certificate and
any Offshore Global Certificate may be transferred in accordance with the rules
and procedures of the Depositary and the provisions of Section 3.06.
Beneficial interests in the U.S. Global Certificate or an Offshore Global
Certificate shall be delivered to all beneficial owners in the form of U.S.
Physical Certificates or Offshore Physical Certificates, as the case may be, if
(i) the Depositary notifies the Trustee that it is unwilling or unable to
continue as Depositary for the U.S. Global Certificate or such Offshore Global
Certificate, as the case may be, and a successor depositary is not appointed by
the Trustee within 90 days of such notice or (ii) an Event of Default has
occurred and is continuing and the Registrar has received a request from the
Depositary to issue Physical Certificates.

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

                 (d)      In connection with the transfer of the entire U.S.
Global Certificate or an entire Offshore Global Certificate to the beneficial
owners thereof pursuant to paragraph (b) of this Section 3.05, such U.S. Global
Certificate or Offshore Global Certificate, as the case may be, shall be deemed
to be surrendered to the Trustee for cancellation, and the Trustee shall
execute, authenticate and deliver, to each beneficial owner identified by the
Depositary in exchange for its beneficial interest in such U.S. Global
Certificate or Offshore Global Certificate, as the case may be, an equal
aggregate principal amount of U.S. Physical Certificates or Offshore Physical
Certificates, as the case may be, of authorized denominations.

                 (e)      Any U.S. Physical Certificate delivered in exchange
for an interest in the U.S. Global Certificate pursuant to paragraph (b) of
this Section 3.05 shall, except as otherwise provided by paragraph (f) of
Section 3.06, bear the Private Placement Legend.

                 (f)      Any Offshore Physical Certificate delivered in
exchange for an interest in an Offshore Global Certificate pursuant to
paragraph (b) of this Section shall, except as
<PAGE>   31
                                       25

otherwise provided by paragraph (f) of Section 3.06, bear the applicable legend
regarding transfer restrictions set forth in Section 3.02(a).

                 (g)      The registered holder of the U.S. Global Certificate
or any Offshore Global Certificate 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
Agreement or the Certificates.

                 Section 3.06.  Special Transfer Provisions.  Unless and until
(i) an Initial Certificate is sold under an effective Registration Statement,
or (ii) an Initial Certificate is exchanged for an Exchange Certificate
pursuant to an effective Exchange Offer Registration Statement, in each case
pursuant to the Registration Rights Agreement, the following provisions shall
apply to such Initial Certificates:

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

                          (i)     The Registrar shall register the transfer of
                 any Certificate, whether or not such Certificate bears the
                 Private Placement Legend, if (x) the requested transfer is at
                 least three years after the later of the original issue date
                 of the Certificates and the last date on which such
                 Certificate was held by the Company or any affiliate of any
                 such persons or (y) the proposed transferee has delivered to
                 the Registrar a letter substantially in the form of Exhibit D
                 to the Related Pass Through Trust Agreement and the aggregate
                 principal amount of the Certificates being transferred is at
                 least $100,000.

                          (ii)    If the proposed transferor is an Agent Member
                 holding a     beneficial interest in the U.S. Global
                 Certificate, 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 of the transfer and a decrease in
                 the principal amount of such U.S. Global Certificate in an
                 amount equal to the principal amount of the beneficial
                 interest in such U.S. Global Certificate to be transferred,
                 and the Company shall execute, and the Trustee shall
                 authenticate and deliver to the transferor or at its
                 direction, one or more U.S. Physical Certificates of like
                 tenor and amount.

                 (b)      Transfers to QIBs.  The following provisions shall
         apply with respect to the registration of any proposed transfer of an
         Initial Certificate to a QIB (excluding Non-U.S. Persons):
<PAGE>   32
                                       26


                          (i)     If the Certificate to be transferred consists
                 of U.S. Physical  Certificates or an interest in any Temporary
                 Offshore Global Certificate, 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
                 Initial Certificate stating, or has otherwise advised the
                 Trustee 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 Initial Certificate stating, or has otherwise
                 advised the Trustee and the Registrar in writing, that it is
                 purchasing the Initial Certificate for its own account or an
                 account with respect to which it exercises sole investment
                 discretion and that it, or the Person on whose behalf it is
                 acting with respect to 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 Trust and/or 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.

                          (ii)    Upon receipt by the Registrar of the
                 documents referred to in clause (i) above and instructions
                 given in accordance with the Depositary's and the Registrar's
                 procedures therefor, the Registrar shall reflect on its books
                 and records the date of such transfer and an increase in the
                 principal amount of the U.S. Global Certificate in an amount
                 equal to the principal amount of the U.S.  Physical
                 Certificates or interests in the Temporary Offshore Global
                 Certificate, as the case may be, being transferred, and the
                 Trustee shall cancel such Physical Certificates or decrease
                 the amount of such Temporary Offshore Global Certificate so
                 transferred.

                 (c)      Transfers of Interests in the Permanent Offshore
         Global Certificate or Offshore Physical Certificates.  The Registrar
         shall register any transfer of interests in the Permanent Offshore
         Global Certificate or Offshore Physical Certificates without requiring
         any additional certification.

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

                          (i)     Prior to the Offshore Certificates Exchange
                 Date, the Registrar shall register any proposed transfer of an
                 Initial Certificate to a Non-U.S. Person upon receipt of a
                 certificate substantially in the form set forth as Exhibit C
                 to the Related Pass Through Trust Agreement from the proposed
                 transferor.
<PAGE>   33
                                       27

                          (ii)    On and after the Offshore Certificates
                 Exchange Date, the Registrar shall register any proposed
                 transfer to any Non-U.S. Person if the Certificate to be
                 transferred is a U.S. Physical Certificate or an interest in
                 the U.S. Global Certificate, upon receipt of a certificate
                 substantially in the form of Exhibit C from the proposed
                 transferor.  The Registrar shall promptly send a copy of such
                 certificate to the Company.

                          (iii)   Upon receipt by the Registrar of (x) the
                 documents, if any, required by paragraph (ii) 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 of such transfer and a decrease in
                 the principal amount of such U.S. Global Certificate in an
                 amount equal to the principal amount of the beneficial
                 interest in such U.S. Global Certificate to be transferred,
                 and (B) 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 Certificate in an amount equal to the
                 principal amount of the U.S. Physical Certificate or the U.S.
                 Global Certificate, as the case may be, to be transferred, and
                 the Trustee shall cancel the Physical Certificate, if any, so
                 transferred or decrease the amount of such U.S. Global
                 Certificate.

                 (e)      Private Placement Legend.  Upon the transfer,
         exchange or replacement of Certificates not bearing the Private
         Placement Legend, the Registrar shall deliver Certificates that do not
         bear the Private Placement Legend.  Upon the transfer, exchange or
         replacement of Certificates bearing the Private Placement Legend, the
         Registrar shall deliver only Certificates that bear the Private
         Placement Legend unless either (i) the circumstances contemplated by
         paragraph (a)(i)(x) or (e)(ii) of this Section 3.06 exist or (ii)
         there is delivered to the Registrar an Opinion of Counsel 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 Certificate
         bearing the Private Placement Legend, each Holder of such a
         Certificate acknowledges the restrictions on transfer of such
         Certificate set forth in this Agreement and agrees that it will
         transfer such Certificate only as provided in this Agreement.  The
         Registrar shall not register a transfer of any Certificate unless such
         transfer complies with the restrictions on transfer of such
         Certificate set forth in this Agreement.  In connection with any
         transfer of Certificates, each Certificateholder agrees by its
         acceptance of the Certificates to furnish the Registrar or the Trustee
         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,
<PAGE>   34
                                       28

         the registration requirements of the Securities Act; provided that the
         Registrar shall not be required to determine the sufficiency of any
         such certifications, legal opinions or other information.

                 Until such time as no Certificates remain Outstanding, the
Registrar shall retain copies of all letters, notices and other written
communications received pursuant to Section 3.05 or this Section 3.06.  The
Trustee, if not the Registrar at such time, 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 3.07.  Mutilated, Destroyed, Lost or Stolen
Certificates.  If (a) any mutilated Certificate is surrendered to the Registrar
or the Registrar receives evidence to its satisfaction of the destruction, loss
or theft of any Certificate and (b) there is delivered to the Registrar and the
Trustee such security, indemnity or bond, as may be required by them to save
each of them harmless, then, in the absence of notice to the Registrar or the
Trustee that such destroyed, lost or stolen Certificate has been acquired by a
bona fide purchaser, and provided that the requirements of Section 8-405 of the
Uniform Commercial Code in effect in any applicable jurisdiction are met, the
Trustee shall execute, authenticate and deliver, in exchange for or in lieu of
any such mutilated, destroyed, lost or stolen Certificate, a new Certificate or
Certificates, in authorized denominations and of like Fractional Undivided
Interest and bearing a number not contemporaneously outstanding.

                 In connection with the issuance of any new Certificate under
this Section 3.07, the Trustee may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Trustee
and the Registrar) connected therewith.

                 Any duplicate Certificate issued pursuant to this Section 3.07
shall constitute conclusive evidence of the appropriate Fractional Undivided
Interest in the Trust, as if originally issued, whether or not the lost, stolen
or destroyed Certificate shall be found at any time.

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

                 Section 3.08.  Persons Deemed Owners.  Prior to due
presentment of a Certificate for registration of transfer, the Trustee, the
Registrar and any Paying Agent may treat the Person in whose name any
Certificate is registered (as of the day of determination) as the owner of such
Certificate for the purpose of receiving distributions pursuant to Article
<PAGE>   35
                                       29

IV and for all other purposes whatsoever, and none of the Trustee, the
Registrar or any Paying Agent shall be affected by any notice to the contrary.

                 Section 3.09.  Cancellation.  All Certificates surrendered for
payment or transfer or exchange shall, if surrendered to the Trustee or any
agent of the Trustee other than the Registrar, be delivered to the Registrar
for cancellation and shall promptly be cancelled by it.  No Certificates shall
be authenticated in lieu of or in exchange for any Certificates cancelled as
provided in this Section, except as expressly permitted by this Agreement.  All
cancelled Certificates held by the Registrar shall be destroyed and a
certification of their destruction delivered to the Trustee.

                 Section 3.10.  Temporary Certificates.  Until definitive
Certificates are ready for delivery, the Trustee shall authenticate temporary
Certificates.  Temporary Certificates shall be substantially in the form of
definitive Certificates but may have insertions, substitutions, omissions and
other variations determined to be appropriate by the officers executing the
temporary Certificates, as evidenced by their execution of such temporary
Certificates.  If temporary Certificates are issued, the Trustee will cause
definitive Certificates to be prepared without unreasonable delay.  After the
preparation of definitive Certificates, the temporary Certificates shall be
exchangeable for definitive Certificates upon surrender of the temporary
Certificates at the office or agency of the Trustee designated for such purpose
pursuant to Section 7.12, without charge to the Certificateholder.  Upon
surrender for cancellation of any one or more temporary Certificates, the
Trustee shall execute, authenticate and deliver in exchange therefor a like
face amount of definitive Certificates of authorized denominations.  Until so
exchanged, the temporary Certificates shall be entitled to the same benefits
under this Agreement as definitive Certificates.

                 Section 3.11.  Limitation of Liability for Payments.  All
payments and distributions made to Certificateholders shall be made only from
the Trust Property and only to the extent that the Trustee shall have
sufficient income or proceeds from the Trust Property to make such payments in
accordance with the terms of Article IV of this Agreement.  Each
Certificateholder, by its acceptance of a Certificate, agrees that it will look
solely to the income and proceeds from the Trust Property for any payment or
distribution due to such Certificateholder pursuant to the terms of this
Agreement and that it will not have any recourse to the Company, the Trustee,
the Loan Trustees, the Liquidity Providers, the Owner Trustees or the Owner
Participants, except as otherwise expressly provided herein or in the
Intercreditor Agreement.

                 The Company is a party to this Agreement solely for purposes
of meeting the requirements of the Trust Indenture Act, and therefore shall not
have any right, obligation or liability hereunder (except as otherwise
expressly provided herein).

                               CERTIFICATEHOLDERS

                 Section 4.01.  Certificate Account and Special Payments
Account.  (a)  The Trustee shall establish and maintain on behalf of the
Certificateholders a Certificate Account as one or more non-interest-bearing
accounts.  The Trustee shall hold such Certificate Account in trust for the
benefit of the Certificateholders, and shall make or permit withdrawals
therefrom only as provided in this Agreement.  On each day when a Scheduled
Payment is made to the Trustee under the Intercreditor Agreement with respect
to the Certificates, the Trustee, upon receipt thereof, shall immediately
deposit the aggregate amount of such Scheduled Payment in such Certificate
Account.

                 (b)      The Trustee shall establish and maintain on behalf of
the Certificateholders a Special Payments Account as one or more accounts,
which shall be non-interest bearing except as provided in Section 4.04. The
Trustee shall hold the Special Payments Account in trust for the benefit of the
Certificateholders and shall make or permit withdrawals therefrom only as
provided in this Agreement.  On each day when one or more Special Payments are
made to the Trustee under the Intercreditor Agreement and upon payment of the
Special Redemption Premium to the Trustee under the Note Purchase Agreement
with respect to the Certificates, the Trustee, upon receipt thereof, shall
immediately deposit the aggregate amount of such Special Payments in such
Special Payments Account.

                 (c)      The Trustee shall present (or, if applicable, cause
the Subordination Agent to present) to the related Loan Trustee of each
Equipment Note such Equipment Note on the date of its stated final maturity or,
in the case of any Equipment Note which is to be redeemed in whole pursuant to
the related Indenture, on the applicable redemption date under such Indenture.

                 Section 4.02.  Distributions from Certificate Account and
Special Payments Account.  (a)  On each Regular Distribution Date with respect
to a series of Certificates or as soon thereafter as the Trustee has confirmed
receipt of the payment of all or any part of the Scheduled Payments due on the
Equipment Notes held (subject to the Intercreditor Agreement) in the related
Trust on such date, the Trustee shall distribute out of the applicable
Certificate Account the entire amount deposited therein pursuant to Section
4.01(a).  There shall be so distributed to each Certificateholder of record of
such series on the Record Date with respect to such Regular Distribution Date
(other than as provided in Section 11.01 concerning the final distribution) by
check mailed to such Certificateholder, at the address appearing in the
Register, such Certificateholder's pro rata share (based on the Fractional
Undivided Interest in the Trust held by such Certificateholder)
<PAGE>   37
                                       31

of the total amount in the applicable Certificate Account, except that, with
respect to Certificates registered on the Record Date in the name of a Clearing
Agency (or its nominee), such distribution shall be made by wire transfer in
immediately available funds to the account designated by such Clearing Agency
(or such nominee).

                 (b)      On each Special Distribution Date with respect to any
Special Payment with respect to the Certificates or as soon thereafter as the
Trustee has confirmed receipt of any Special Payments due on the Equipment
Notes held (subject to the Intercreditor Agreement) in the related Trust or
realized upon the sale of such Equipment Notes or receipt of the Special
Redemption Premium, the Trustee shall distribute out of the applicable Special
Payments Account the entire amount of such applicable Special Payment deposited
therein pursuant to Section 4.01(b).  There shall be so distributed to each
Certificateholder of record of such series on the Record Date with respect to
such Special Distribution Date (other than as provided in Section 11.01
concerning the final distribution) by check mailed to such Certificateholder,
at the address appearing in the Register, such Certificateholder's pro rata
share (based on the Fractional Undivided Interest in the related Trust held by
such Certificateholder) of the total amount in the applicable Special Payments
Account on account of such Special Payment, except that, with respect to
Certificates registered on the Record Date in the name of a Clearing Agency (or
its nominee), such distribution shall be made by wire transfer in immediately
available funds to the account designated by such Clearing Agency (or such
nominee).

                 (c)      The Trustee shall, at the expense of the Company,
cause notice of each Special Payment with respect to a series of Certificates
to be mailed to each Certificateholder at his address as it appears in the
Register.  In the event of redemption or purchase of Equipment Notes held in
the related Trust, such notice shall be mailed not less than 15 days prior to
the Special Distribution Date for the Special Payment resulting from such
redemption or purchase, which Special Distribution Date shall be the date of
such redemption or purchase.  In the event that any Special Redemption Premium
is to be paid by the Company to the Trustee under the Note Purchase Agreement,
such notice shall be mailed, together with the notice by the Escrow Paying
Agent under Section 2.06 of the Escrow Agreement, not less than 20 days prior
to the Special Distribution Date for such amount, which Special Distribution
Date shall be the Final Withdrawal Date.  In the case of any other Special
Payments, such notice shall be mailed as soon as practicable after the Trustee
has confirmed that it has received funds for such Special Payment, stating the
Special Distribution Date for such Special Payment which shall occur not less
than 15 days after the date of such notice and as soon as practicable
thereafter.  Notices mailed by the Trustee shall set forth:

                 (i)      the Special Distribution Date and the Record Date
         therefor (except as otherwise provided in Section 11.01);
<PAGE>   38
                                       32

                 (ii)     the amount of the Special Payment for each $1,000
         face amount Certificate and the amount thereof constituting principal,
         premium, if any, and interest;

                 (iii)    the reason for the Special Payment; and

                 (iv)     if the Special Distribution Date is the same date as
         a Regular Distribution Date for the Certificates, the total amount to
         be received on such date for each $1,000 face amount Certificate.

If the amount of (i) premium, if any, payable upon the redemption or purchase
of an Equipment Note or (ii) the Special Redemption Premium, if any, has not
been calculated at the time that the Trustee mails notice of a Special Payment,
it shall be sufficient if the notice sets forth the other amounts to be
distributed and states that any premium received will also be distributed.

                 If any redemption of the Equipment Notes held in any Trust is
cancelled, the Trustee, as soon as possible after learning thereof, shall cause
notice thereof to be mailed to each Certificateholder at its address as it
appears on the Register.

                 Section 4.03.  Statements to Certificateholders.  (a)  On each
Regular Distribution Date and Special Distribution Date, the Trustee will
include with each distribution of a Scheduled Payment or Special Payment, as
the case may be, to Certificateholders a statement setting forth the
information provided below (in the case of a Special Payment, including any
Special Redemption Premium, reflecting in part the information provided by the
Escrow Paying Agent under the Escrow Agreement).  Such statement shall set
forth (per $1,000 aggregate principal amount of Certificate as to (ii), (iii),
(iv) and (v) below) the following information:

                 (i)      the aggregate amount of funds distributed on such
         Distribution Date under the Agreement and under the Escrow Agreement,
         indicating the amount allocable to each source;

                 (ii)     the amount of such distribution under this Agreement
         allocable to principal and the amount allocable to premium (including
         the Special Redemption Premium), if any;

                 (iii)    the amount of such distribution under this Agreement
         allocable to interest;

                 (iv)     the amount of such distribution under the Escrow
         Agreement allocable to interest;
<PAGE>   39
                                       33


                 (v)      the amount of such distribution under the Escrow
         Agreement allocable to Deposits; and

                 (vi)     the Pool Balance and the Pool Factor.

                 With respect to the Certificates registered in the name of a
Clearing Agency or its nominee, on the Record Date prior to each Distribution
Date, the Trustee will request from the Clearing Agency a securities position
listing setting forth the names of all Clearing Agency Participants reflected
on the Clearing Agency's books as holding interests in the Certificates on such
Record Date.  On each Distribution Date, the Trustee will mail to each such
Clearing Agency Participant the statement described above and will make
available additional copies as requested by such Clearing Agency Participant
for forwarding to holders of interests in the Certificates.

                 (b)      Within a reasonable period of time after the end of
each calendar year but not later than the latest date permitted by law, the
Trustee shall furnish to each Person who at any time during such calendar year
was a Certificateholder of record a statement containing the sum of the amounts
determined pursuant to clauses (a)(i), (a)(ii), (a)(iii), (a)(iv) and (a)(v)
above with respect to the related Trust for such calendar year or, in the event
such Person was a Certificateholder of record during a portion of such calendar
year, for the applicable portion of such year, and such other items as are
readily available to the Trustee and which a Certificateholder shall reasonably
request as necessary for the purpose of such Certificateholder's preparation of
its federal income tax returns.  Such statement and such other items shall be
prepared on the basis of information supplied to the Trustee by the Clearing
Agency Participants and shall be delivered by the Trustee to such Clearing
Agency Participants to be available for forwarding by such Clearing Agency
Participants to the holders of interests in the Certificates in the manner
described in Section 4.03(a).

                 (c)      Promptly following (i) the Transfer Date, if there
has been any change in the information set forth in clauses (x), (y) and (z)
below from that set forth in page 65 of the Offering Memorandum, and (ii) any
early redemption or purchase of, or any default in the payment of principal or
interest in respect of, any of the Equipment Notes held in the Trust, or any
Final Withdrawal, the Trustee shall furnish to Certificateholders of record on
such date a statement setting forth (x) the expected Pool Balances for each
subsequent Regular Distribution Date following the Transfer Date, (y) the
related Pool Factors for such Regular Distribution Dates and (z) the expected
principal distribution schedule of the Equipment Notes, in the aggregate, held
as Trust Property at the date of such notice.  With respect to the Certificates
registered in the name of a Clearing Agency, on the Transfer Date, the Trustee
will request from such Clearing Agency a securities position listing setting
forth the names of all Clearing Agency Participants reflected on such Clearing
Agency's books as holding interests in the Certificates on such date.  The
Trustee will mail to each such Clearing Agency Participant the statement
described above and will make available additional
<PAGE>   40
                                       34

copies as requested by such Clearing Agency Participant for forwarding to
holders of interests in the Certificates.

                 Section 4.04.  Investment of Special Payment Moneys.  Any
money received by the Trustee pursuant to Section 4.01(b) representing a
Special Payment which is not distributed on the date received shall, to the
extent practicable, be invested in Permitted Investments by the Trustee pending
distribution of such Special Payment pursuant to Section 4.02.  Any investment
made pursuant to this Section 4.04 shall be in such Permitted Investments
having maturities not later than the date that such moneys are required to be
used to make the payment required under Section 4.02 on the applicable Special
Distribution Date and the Trustee shall hold any such Permitted Investments
until maturity.  The Trustee shall have no liability with respect to any
investment made pursuant to this Section 4.04, other than by reason of the
willful misconduct or negligence of the Trustee.  All income and earnings from
such investments shall be distributed on such Special Distribution Date as part
of such Special Payment.

         which the Company is merged or the Person which acquires by
         conveyance, transfer or lease substantially all of the assets of the
         Company as an entirety shall execute and deliver to the Trustee
         applicable to the Certificates a duly authorized, valid, binding and
         enforceable agreement in form and substance reasonably satisfactory to
         the Trustee containing an assumption by such successor corporation or
         Person of the due and punctual performance and observance of each
         covenant and condition of the Note Documents and of this Agreement
         applicable to the Certificates to be performed or observed by the
         Company; and

                 (c)      the Company shall have delivered to the Trustee an
         Officer's Certificate of the Company and an Opinion of Counsel of the

conveyance, transfer or lease is made shall succeed to, and be substituted for,
and may exercise every right and power of, the Company under this Agreement
applicable to the Certificates with the same effect as if such successor
corporation or Person had been named as the Company herein.  No such
conveyance, transfer or lease of substantially all of the assets of the Company
as an entirety shall have the effect of releasing any successor corporation or
Person which shall have become such in the manner prescribed in this Section
5.02 from its liability in respect of this Agreement and any Note Document
applicable to the Certificates to which it is a party.


                                   ARTICLE VI

                                    DEFAULT

                 Section 6.01.  Events of Default.  (a)  Exercise of Remedies.
Upon the occurrence and during the continuation of any Indenture Default under
any Indenture, the Trustee may, to the extent it is the Controlling Party at
such time (as determined pursuant to the Intercreditor Agreement), direct the
exercise of remedies as provided in the Intercreditor Agreement.

                 (b)      Purchase Rights of Certificateholders.  By acceptance
of its Certificate, each Certificateholder agrees that at any time after the
occurrence and during the
<PAGE>   42
                                       36

continuation of a Triggering Event, each Class D Certificateholder shall have
the right to purchase all, but not less than all, of the Certificates, the
Class A Certificates and the Class B Certificates upon ten days' written notice
to the Trustee, the Class A Trustee, the Class B Trustee and each other Class D
Certificateholder, provided that (A) if prior to the end of such ten-day period
any other Class D Certificateholder notifies such purchasing Class D
Certificateholder that such other Class D Certificateholder wants to
participate in such purchase, then such other Class D Certificateholder may
join with the purchasing Class D Certificateholder to purchase all, but not
less than all, of the Certificates, the Class A Certificates and the Class B
Certificates pro rata based on the Fractional Undivided Interest in the Class D
Trust held by each such Class D Certificateholder and (B) if prior to the end
of such ten-day period any other Class D Certificateholder fails to notify the
purchasing Class D Certificateholder of such other Class D Certificateholder's
desire to participate in such a purchase, then such other Class D
Certificateholder shall lose its right to purchase the Certificates pursuant to
this Section 6.01(b).

                 The purchase price with respect to the Certificates shall be
equal to the Pool Balance of the Certificates, together with accrued and unpaid
interest thereon to the date of such purchase, without premium, but including
any other amounts then due and payable to the Certificateholders under this
Agreement, the Intercreditor Agreement, the Escrow Agreement or any Note
Document or on or in respect of the Certificates; provided, however, that (i)
if such purchase occurs after the record date specified in Section 2.03(b) of
the Escrow Agreement relating to the distribution of unused Deposits and
accrued and unpaid interest thereunder, such purchase price shall be reduced by
the aggregate amount of unused Deposits and interest to be distributed under
the Escrow Agreement (which deducted amounts shall remain distributable to, and
may be retained by, the Certificateholder as of such Record Date) and (ii) if
such purchase occurs after a Record Date, such purchase price shall be reduced
by the amount to be distributed hereunder on the related Distribution Date
(which deducted amounts shall remain distributable to, and may be retained by,
the Certificateholder as of such Record Date); provided further that no such
purchase of Certificates shall be effective unless the purchaser(s) shall
certify to the Trustee that contemporaneously with such purchase, such
purchaser(s) is purchasing, pursuant to the terms of this Agreement and the
Other Agreements, the Certificates, the Class A Certificates and the Class B
Certificates which are senior to the securities held by such purchaser(s).
Each payment of the purchase price of the Certificates referred to in the first
sentence hereof shall be made to an account or accounts designated by the
Trustee and each such purchase shall be subject to the terms of this Section
6.01(b).  Each Certificateholder agrees by its acceptance of its Certificate
that it will, subject to Section 3.04 of this Agreement, upon payment from such
Class D Certificateholder(s), as the case may be, of the purchase price set
forth in the first sentence of this paragraph, forthwith sell, assign, transfer
and convey to the purchaser(s) thereof (without recourse, representation or
warranty of any kind except for its own acts), all of the right, title,
interest and obligation of such Certificateholder in this Agreement, the Escrow
Agreement, the Deposit Agreement, the Intercreditor Agreement, the Liquidity
Facilities, the
<PAGE>   43
                                       37

Note Documents and all Certificates and Escrow Receipts held by such
Certificateholder (excluding all right, title and interest under any of the
foregoing to the extent such right, title or interest is with respect to an
obligation not then due and payable as respects any action or inaction or state
of affairs occurring prior to such sale) and the purchaser shall assume all of
such Certificateholder's obligations under this Agreement, the Escrow
Agreement, the Deposit Agreement, the Intercreditor Agreement, the Liquidity
Facilities, the Note Documents and all such Certificates and Escrow Receipts.
The Certificates will be deemed to be purchased on the date payment of the
purchase price is made notwithstanding the failure of the Certificateholders to
deliver any Certificates and, upon such a purchase, (i) the only rights of the
Certificateholders will be to deliver the Certificates to the purchaser(s) and
receive the purchase price for such Certificates and (ii) if the purchaser(s)
shall so request, such Certificateholder will comply with all the provisions of
Section 3.04 of this Agreement to enable new Certificates to be issued to the
purchaser in such denominations as it shall request.  All charges and expenses
in connection with the issuance of any such new Certificates shall be borne by
the purchaser thereof.

                 As used in this Section 6.01, the terms "Class A
Certificateholder", "Class A Trust", "Class A Certificate", "Class A Trustee",
"Class B Certificate", "Class B Certificateholder", "Class B Trust", "Class B
Trustee", "Class D Certificateholder" and "Class D Trust", shall have the
respective meanings assigned to such terms in the Intercreditor Agreement.

                 Section 6.02.  Incidents of Sale of Equipment Notes.  Upon any
sale of all or any part of the Equipment Notes held in the Trust made either
under the power of sale given under this Agreement or otherwise for the
enforcement of this Agreement, the following shall be applicable:

                 (a)      Certificateholders and Trustee May Purchase Equipment
         Notes.  Any Certificateholder, the Trustee in its individual or any
         other capacity or any other Person may bid for and purchase any of the

         of sale, may hold, retain, possess and dispose of such Equipment Notes
         in their own absolute right without further accountability.

                 (b)      Receipt of Trustee Shall Discharge Purchaser.  The
         receipt of the Trustee making such sale shall be a sufficient
         discharge to any purchaser for his purchase money, and, after paying
         such purchase money and receiving such receipt, such purchaser or its
         personal representative or assigns shall not be obliged to see to the
         application of such purchase money, or be in any way answerable for
         any loss, misapplication or nonapplication thereof.

                 (c)      Application of Moneys Received upon Sale.  Any moneys
         collected by the Trustee upon any sale made either under the power of
         sale given by this
<PAGE>   44
                                       38

         Agreement or otherwise for the enforcement of this Agreement shall be
         applied as provided in Section 4.02.

                 Section 6.03.  Judicial Proceedings Instituted by Trustee;
Trustee May Bring Suit.  If there shall be a failure to make payment of the
principal of, premium, if any, or interest on any Equipment Note held in the
Trust, or if there shall be any failure to pay Rent (as defined in the relevant
Lease) under any Lease when due and payable, then the Trustee, in, its own name
and as trustee of an express trust, as holder of such Equipment Notes, to the
extent permitted by and in accordance with the terms of any related
Intercreditor Agreement and any related Note Documents (subject to rights of
the applicable Owner Trustee or Owner Participant to cure any such failure to
pay principal of, premium, if any, or interest on any Equipment Note or to pay
Rent under any Lease in accordance with the applicable Indenture), shall be
entitled and empowered to institute any suits, actions or proceedings at law,
in equity or otherwise, for the collection of the sums so due and unpaid on
such Equipment Notes or under such Lease and may prosecute any such claim or
proceeding to judgment or final decree with respect to the whole amount of any
such sums so due and unpaid.

                 Section 6.04.  Control by Certificateholders.  Subject to
Section 6.03 and the Intercreditor Agreement, the Certificateholders holding
Certificates evidencing Fractional Undivided Interests aggregating not less
than a majority in interest in the related Trust shall have the right to direct
the time, method and place of conducting any proceeding for any remedy
available to the Trustee with respect to the Trust or pursuant to the terms of
the Intercreditor Agreement, or exercising any trust or power conferred on the
Trustee under this Agreement or the Intercreditor Agreement, including any
right of the Trustee as Controlling Party under the Intercreditor Agreement or
as holder of the Equipment Notes held in the related Trust; provided, however,
that

                 (a)      such Direction shall not in the opinion of the
         Trustee be in conflict with any rule of law or with this Agreement and
         would not involve the Trustee in personal liability or expense,

                 (b)      the Trustee shall not determine that the action so
         directed would be unjustly prejudicial to the Certificateholders not
         taking part in such Direction, and

                 (c)      the Trustee may take any other action deemed proper
         by the Trustee which is not inconsistent with such Direction.

                 Section 6.05.  Waiver of Past Defaults.  Subject to any
related Intercreditor Agreement, the Certificateholders holding Certificates of
a series evidencing Fractional Undivided Interests aggregating not less than a
majority in interest in the Trust (i) may on behalf of all of the
Certificateholders waive any past Event of Default hereunder and its
<PAGE>   45
                                       39

consequences or (ii) if the Trustee is the Controlling Party, may direct the
Trustee to instruct the applicable Loan Trustee to waive any past Indenture
Event of Default under any related Indenture and its consequences, and thereby
annul any Direction given by such Certificateholders or the Trustee to such
Loan Trustee with respect thereto, except a default:

                 (a)      in the deposit of any Scheduled Payment or Special
         Payment under Section 4.01 or in the distribution of any payment under
         Section 4.02 on the Certificates, or

                 (b)      in the payment of the principal of (premium, if any)
         or interest on the Equipment Notes held in the Trust, or

                 (c)      in respect of a covenant or provision hereof which
         under Article IX hereof cannot be modified or amended without the
         consent of each Certificateholder holding an Outstanding Certificate
         of a series affected thereby.

Upon any such waiver, such default shall cease to exist with respect to the
Certificates and any Event of Default arising therefrom shall be deemed to have
been cured for every purpose and any direction given by the Trustee on behalf
of the Certificateholders to the relevant Loan Trustee shall be annulled with
respect thereto; but no such waiver shall extend to any subsequent or other
default or Event of Default or impair any right consequent thereon.  Upon any
such waiver, the Trustee shall vote the Equipment Notes issued under the
relevant Indenture to waive the corresponding Indenture Event of Default.

                 Section 6.06.  Right of Certificateholders to Receive Payments
Not to Be Impaired.  Anything in this Agreement to the contrary
notwithstanding, including, without limitation, Section 6.07 hereof, but
subject to the Intercreditor Agreement, the right of any Certificateholder to
receive distributions of payments required pursuant to Section 4.02 hereof on
the applicable Certificates when due, or to institute suit for the enforcement

Special Distribution Date, shall not be impaired or affected without the
consent of such Certificateholder.

Under Certain Conditions.  A Certificateholder shall not have the right to
institute any suit, action or proceeding at law or in equity or otherwise with
respect to this Agreement, for the appointment of a receiver or for the
enforcement of any other remedy under this Agreement, unless:

         written notice to the Trustee of a continuing Event of Default;

                                       40

                 (b)      Certificateholders holding Certificates evidencing
         Fractional Undivided Interests aggregating not less than 25% of the
         related Trust shall have requested the Trustee in writing to institute
         such action, suit or proceeding and shall have offered to the Trustee
         indemnity as provided in Section 7.03(e);

                 (c)      the Trustee shall have refused or neglected to
         institute any such action, suit or proceeding for 60 days after
         receipt of such notice, request and offer of indemnity; and

                 (d)      no direction inconsistent with such written request
         shall have been given to the Trustee during such 60-day period by
         Certificateholders holding Certificates evidencing Fractional
         Undivided Interests aggregating not less than a majority in interest

Certificateholders shall have any right in any manner whatsoever hereunder or
under the related Trust Supplement or under the Certificates to (i) surrender,
impair, waive, affect, disturb or prejudice any property in the Trust Property
of the Trust, or the lien of any related Indenture on any property subject
thereto, or the rights of the Certificateholders or the holders of the
Equipment Notes, (ii) obtain or seek to obtain priority over or preference with
respect to any other such Certificateholder or (iii) enforce any right under
this Agreement, except in the manner herein provided and for the equal, ratable
and common benefit of all the Certificateholders subject to the provisions of
this Agreement.

                 Section 6.08.  Remedies Cumulative.  Every remedy given
hereunder to the Trustee or to any of the Certificateholders shall not be
exclusive of any other remedy or remedies, and every such remedy shall be
cumulative and in addition to every other remedy given hereunder or now or
hereafter given by statute, law, equity or otherwise.

                 Section 6.09.  Undertaking for Costs.  In any suit for the
enforcement of any right or remedy under this Agreement, or in any suit against
the Trustee for any action taken, suffered or omitted by it as Trustee, a court
may require any party litigant in such suit to file an undertaking to pay the
costs of such suit, and may assess costs against any such party litigant, in
the manner and to the extent provided in the Trust Indenture Act; provided,
however, that neither this Section 6.09 nor the Trust Indenture Act shall be
deemed to authorize any court to require such an undertaking or to make such an
assessment in any suit instituted by the Company.

Except during the continuance of an Event of Default in respect of a Trust, the
Trustee undertakes to perform such duties in respect of the Trust as are
specifically set forth in this Agreement, and no implied covenants or
obligations shall be read into this Agreement against the Trustee.

occurred and is continuing, the Trustee shall exercise such of the rights and
powers vested in it by this Agreement in respect of the Trust, and use the same
degree of care and skill in their exercise, as a prudent man would exercise or
use under the circumstances in the conduct of his own affairs.

                 (c)      No provision of this Agreement 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

                 (i)      this Subsection shall not be construed to limit the
         effect of Subsection (a) of this Section 7.01; and

hereunder known to the Trustee, unless such default shall have been cured or
waived; provided, however, that, except in the case of a default in the payment
of the principal, premium, if any, or interest on any Equipment 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 shall determine that
the withholding of such notice is in the interests of the Certificateholders.

         shall have reasonable grounds for believing that repayment of such
         funds or adequate indemnity against such risk is not reasonably
         assured to it.

                 Section 7.07.  Compensation and Reimbursement.  The Company
agrees:

                 (a)      to pay, or cause to be paid, to the Trustee from time
         to time  reasonable compensation for all services rendered by it
         hereunder (which compensation shall not be limited by any provision of
         law in regard to the compensation of a trustee of an express trust);
         and

                 (b)      to reimburse, or cause to be reimbursed, the Trustee
         upon its request for all reasonable out- of-pocket expenses,
         disbursements and advances incurred or made by the Trustee in
         accordance with any provision of this Agreement or the Intercreditor
         Agreement (including the reasonable compensation and the expenses and
         disbursements of its agents and counsel), except any such expense,
         disbursement or advance as may be attributable to its negligence,
         willful misconduct or bad faith or as may be incurred due to the
         Trustee's breach of its representations and warranties set forth in
         Section 7.15; and

                 (c)      to indemnify the Trustee with respect to the
         Certificates, pursuant to Section 8.1 of the Owned Aircraft
         Participation Agreements and Section 9.1 of the Leased Aircraft
         Participation Agreements, as the case may be.

                 The Trustee shall be entitled to reimbursement from, and shall
have a lien prior to the Certificates upon, all property and funds held or
collected by the Trustee in its capacity as Trustee for any tax incurred
without negligence, bad faith or willful misconduct, on its part, arising out
of or in connection with the acceptance or administration of the Trust (other
than any tax attributable to the Trustee's compensation for serving as such),
including any costs and expenses incurred in contesting the imposition of any
such tax.  The Trustee shall notify the Company of any claim for any tax for
which it may seek reimbursement.  If the Trustee reimburses itself from the
Trust Property of such Trust for any such tax, it will mail a brief report
within 30 days setting forth the amount of such tax and the circumstances
thereof to all Certificateholders as their names and addresses appear in the
Register.

                 Section 7.08.  Corporate Trustee Required; Eligibility.  The
Trust shall at all times have a Trustee which shall be eligible to act as a
trustee under Section 310(a) of the Trust Indenture Act and shall have a
combined capital and surplus of at least $75,000,000 (or a combined capital and
surplus in excess of $5,000,000 and the obligations of which, whether now in
existence or hereafter incurred, are fully and unconditionally guaranteed by a
corporation organized and doing business under the laws of the United States,
any state or territory thereof or of the District of Columbia and having a
combined capital and surplus of at least $75,000,000).  If such corporation
publishes reports of conditions at least annually, pursuant to law or to the
requirements of federal, state, territorial or District of Columbia supervising
or examining authority, then for the purposes of this Section 7.08 the combined
<PAGE>   51
                                       45

capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of conditions so
published.

                 In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 7.08 to act as Trustee of the
Trust, the Trustee shall resign immediately as Trustee of the Trust in the
manner and with the effect specified in Section 7.09.

                 Section 7.09.  Resignation and Removal; Appointment of
Successor.  (a)  No resignation or removal of the Trustee and no appointment of
a successor Trustee of the Trust pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee under
Section 7.10.

                 (b)      The Trustee may resign at any time as Trustee of the
Trust by giving prior written notice thereof to the Company, the Authorized
Agents, the Owner Trustees and the Loan Trustees.  If an instrument of
acceptance by a successor Trustee shall not have been delivered to the Company,
the Owner Trustees and the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

                 (c)      The Trustee may be removed at any time by Direction
of the Certificateholders holding Certificates evidencing Fractional Undivided
Interests aggregating not less than a majority in interest in such Trust
delivered to the Trustee and to the Company, the Owner Trustees and the Loan
Trustees.

                 (d)      If at any time in respect of the Trust:

                 (i)      the Trustee shall fail to comply with Section 310 of
         the Trust Indenture Act, if applicable, after written request therefor
         by the Company or by any Certificateholder who has been a bona fide
         Certificateholder for at least six months; or

                 (ii)     the Trustee shall cease to be eligible under Section
         7.08 and shall fail to resign after written request therefor by the
         Company or by any such Certificateholder; or

                 (iii)    the Trustee shall become incapable of acting or shall
         be adjudged a bankrupt or insolvent, or a receiver of the Trustee or
         of its property shall be appointed or any public officer shall take
         charge or control of the Trustee or of its property or affairs for the
         purpose of rehabilitation, conservation or liquidation;
<PAGE>   52
                                       46

then, in any case, (i) the Company may remove the Trustee or (ii) any
Certificateholder who has been a bona fide Certificateholder for at least six
months may, on behalf of itself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee of the Trust.

                 (e)      If a Responsible Officer of the Trustee shall obtain
actual knowledge of an Avoidable Tax (as defined below) in respect of any Trust
which has been or is likely to be asserted, the Trustee shall promptly notify
the Company and shall, within 30 days of such notification, resign as Trustee
of such Trust hereunder unless within such 30-day period the Trustee shall have
received notice that the Company has agreed to pay such tax.  The Company shall
promptly appoint a successor Trustee of such Trust in a jurisdiction where
there are no Avoidable Taxes.  As used herein, an "Avoidable Tax" in respect of
such Trust means a state or local tax:  (i) upon (w) such Trust, (x) such Trust
Property, (y) Certificateholders of the Trust or (z) the Trustee for which the
Trustee is entitled to seek reimbursement from the Trust Property of such
Trust, and (ii) which would be avoided if the Trustee were located in another
state, or jurisdiction within a state, within the United States of America.  A
tax shall not be an Avoidable Tax in respect of any Trust if the Company or any
Owner Trustee shall agree to pay, and shall pay, such tax.

                 (f)      If the Trustee shall resign, be removed or become
incapable of acting as Trustee of the Trust or if a vacancy shall occur in the
office of the Trustee of the Trust for any cause, the Company shall promptly
appoint a successor Trustee.  If, within one year after such resignation,
removal or incapability, or other occurrence of such vacancy, a successor
Trustee shall be appointed by Direction of the Certificateholders holding
Certificates evidencing Fractional Undivided Interests aggregating not less
than a majority in interest in such Trust delivered to the Company, the Owner
Trustees, the Loan Trustee and the retiring Trustee, then the successor Trustee
so appointed shall, with the approval of the Company of such appointment, which
approval shall not be unreasonably withheld, forthwith upon its acceptance of
such appointment, become the successor Trustee and supersede the successor
Trustee appointed as provided above.  If no successor Trustee shall have been
so appointed as provided above and accepted appointment in the manner
hereinafter provided, the resigning Trustee or any Certificateholder who has
been a bona fide Certificateholder of the related series for at least six
months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the appointment of a successor Trustee.

                 (g)      The successor Trustee shall give notice of the
resignation and removal of the Trustee and appointment of the successor Trustee
by mailing written notice of such event by first-class mail, postage prepaid,
to the Certificateholders as their names and addresses appear in the Register.
Each notice shall include the name of such successor Trustee and the address of
its Corporate Trust Office.

                                       47

                 Section 7.10.  Acceptance of Appointment by Successor.  Every
successor Trustee appointed hereunder shall execute and deliver to the Company
and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on request of the Company or the successor
Trustee, such retiring Trustee shall execute and deliver an instrument
transferring to such successor Trustee all such rights, powers and trusts of
the retiring Trustee and shall duly assign, transfer and deliver to such
successor Trustee all Trust Property held by such retiring Trustee, subject
nevertheless to its lien, if any, provided for in Section 7.07.  Upon request
of any such successor Trustee, the Company, the retiring Trustee and such
successor Trustee shall execute and deliver any and all instruments containing
such provisions as shall be necessary or desirable to transfer and confirm to,
and for more fully and certainly vesting in, such successor Trustee all such
rights, powers and trusts.

                 No institution shall accept its appointment as a Trustee
hereunder unless at the time of such acceptance such institution shall be
qualified and eligible under this Article VII.

                 Section 7.11.  Merger, Conversion, Consolidation or Succession
to Business.  Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder;
provided, however, that such corporation shall be otherwise qualified and
eligible under this Article VII, without the execution or filing of any paper
or any further act on the part of any of the parties hereto.  In case any
Certificates shall have been executed or authenticated, but not delivered, by
the Trustee then in office, any successor by merger, conversion or
consolidation to such authenticating Trustee may adopt such execution or
authentication and deliver the Certificates so executed or authenticated with
the same effect as if such successor Trustee had itself executed or
authenticated such Certificates.

                 Section 7.12.  Maintenance of Agencies.  (a)  With respect to
each series of Certificates, there shall at all times be maintained an office
or agency in the location set forth in Section 12.04 where Certificates may be
presented or surrendered for registration of transfer or for exchange, and for
payment thereof, and where notices and demands, to or upon the Trustee in
respect of such Certificates or this Agreement may be served; provided,
however, that, if it shall be necessary that the Trustee maintain an office or
agency in another location with respect to the Certificates (e.g., the
Certificates shall be represented by Definitive Certificates and shall be
listed on a national securities exchange), the Trustee will make all reasonable
efforts to establish such an office or agency.  Written notice of the location
of each such other office or agency and of any change of location thereof shall
be given by the Trustee to the Company, any Owner Trustees, the Loan Trustees
(in the case of
<PAGE>   54
                                       48

any Owner Trustee or Loan Trustee, at its address specified in the Note
Documents or such other address as may be notified to the Trustee) and the
Certificateholders.  In the event that no such office or agency shall be
maintained or no such notice of location or of change of location shall be
given, presentations and demands may be made and notices may be served at the
Corporate Trust Office of the Trustee.

                 (b)      There shall at all times be a Registrar and a Paying
Agent hereunder with respect to the Certificates.  Each such Authorized Agent
shall be a bank or trust company, shall be a corporation organized and doing
business under the laws of the United States or any state, with a combined
capital and surplus of at least $75,000,000, or a corporation having a combined
capital and surplus in excess of $5,000,000, the obligations of which are
guaranteed by a corporation organized and doing business under the laws of the
United States or any state, with a combined capital and surplus of at least
$75,000,000, and shall be authorized under such laws to exercise corporate
trust powers, subject to supervision by federal or state authorities.  The
Trustee shall initially be the Paying Agent and, as provided in Section 3.04,
Registrar hereunder with respect to the Certificates.  Each Registrar shall
furnish to the Trustee, at stated intervals of not more than six months, and at
such other times as the Trustee may request in writing, a copy of the Register
maintained by such Registrar.

                 (c)      Any corporation into which any Authorized Agent may
be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, consolidation or conversion to which any Authorized
Agent shall be a party, or any corporation succeeding to the corporate trust
business of any Authorized Agent, shall be the successor of such Authorized
Agent, if such successor corporation is otherwise eligible under this Section
7.12, without the execution or filing of any paper or any further act on the
part of the parties hereto or such Authorized Agent or such successor
corporation.

                 (d)      Any Authorized Agent may at any time resign by giving
written notice of resignation to the Trustee, the Company, any Owner Trustees
and the Loan Trustees.  The Company may, and at the request of the Trustee
shall, at any time terminate the agency of any Authorized Agent by giving
written notice of termination to such Authorized Agent and to the Trustee.
Upon the resignation or termination of an Authorized Agent or in case at any
time any such Authorized Agent shall cease to be eligible under this Section
7.12 (when, in either case, no other Authorized Agent performing the functions
of such Authorized Agent shall have been appointed), the Company shall promptly
appoint one or more qualified successor Authorized Agents, reasonably
satisfactory to the Trustee, to perform the functions of the Authorized Agent
which has resigned or whose agency has been terminated or who shall have ceased
to be eligible under this Section 7.12.  The Company shall give written notice
of any such appointment made by it to the Trustee, any Owner Trustees and the
Loan Trustees; and in each case the Trustee shall mail notice of such
appointment to all Certificateholders as their names and addresses appear on
the Register for such series.

                                       49


                 (e)      The Company agrees to pay, or cause to be paid, from
time to time to each Authorized Agent reasonable compensation for its services
and to reimburse it for its reasonable expenses.

                 Section 7.13.  Money for Certificate Payments to Be Held in
Trust.  All moneys deposited with any Paying Agent for the purpose of any
payment on Certificates shall be deposited and held in trust for the benefit of
the Certificateholders entitled to such payment, subject to the provisions of
this Section 7.13. Moneys so deposited and held in trust shall constitute a
separate trust fund for the benefit of the Certificateholders with respect to
which such money was deposited.

                 The Trustee may at any time, for the purpose of obtaining the
satisfaction and discharge of this Agreement or for any other purpose, direct
any Paying Agent to pay to the Trustee all sums held in trust by such Paying
Agent, such sums to be held by the Trustee upon the same trusts as those upon
which such sums were held by such Paying Agent; and, upon such payment by any
Paying Agent to the Trustee, such Paying Agent shall be released from all
further liability with respect to such money.

                 Section 7.14.  Registration of Equipment Notes in Trustee's
Name.  Subject to the provisions of any Intercreditor Agreement, the Trustee
agrees that all Equipment Notes to be purchased by any Trust and Permitted
Investments, if any, shall be issued in the name of the Trustee as trustee for
the applicable Trust or its nominee and held by the Trustee in trust for the
benefit of the Certificateholders, or, if not so held, the Trustee or its
nominee shall be reflected as the owner of such Equipment Notes or Permitted
Investments, as the case may be, in the register of the issuer of such
Equipment Notes or Permitted Investments, as the case may be.

                 Section 7.15.  Representations and Warranties of Trustee.  The
Trustee hereby represents and warrants, on the Transfer Date, that:

                 (a)      the Trustee is a Delaware banking corporation

         to receive the Trust Property assigned by the Related Trustee, assume
         the obligations under, and perform, the Assignment and Assumption
         Agreement, this Agreement, the Intercreditor Agreement, the Escrow
         Agreement and the Note Documents and has taken all necessary action to
         authorize such receipt, assumption and performance by it of this
         Agreement, the Intercreditor Agreement, the Escrow Agreement and the
         Note Documents to which it is a party;

                 (c)      the receipt of the Trust Property under the
         Assignment and Assumption Agreement and the performance by the Trustee
         of the Assignment and Assumption Agreement, this Trust Supplement, the
         Intercreditor Agreement, the Escrow Agreement and the Note Documents
         (i) will not violate any provision of any United States federal law or
         the law of the state of the United States where it is located
         governing the banking and trust powers of the Trustee or any order,
         writ, judgment, or decree of any court, arbitrator or governmental
         authority applicable to the Trustee or any of its assets, (ii) will
         not violate any provision of the articles of association or by-laws of
         the Trustee, and (iii) will not violate any provision of, or

         or result in the creation or imposition of any lien on any properties
         included in the Trust Property pursuant to the provisions of any
         mortgage, indenture, contract, agreement or other undertaking to which
         it is a party, which violation, default or lien could reasonably be
         expected to have an adverse effect on the Trustee's performance or
         ability to perform its duties hereunder or thereunder or on the
         transactions contemplated herein or therein;

                 (d)      the receipt of the Trust Property under the

         giving of notice to, the filing or registration with, or the taking of
         any other action in respect of, any governmental authority or agency
         of the United States or the state of the United States where it is
         located regulating the banking and corporate trust activities of the
         Trustee; and

                 (e)      The Assignment and Assumption Agreement has been duly
         executed and delivered by the Trustee and this Agreement, the
         Intercreditor Agreement, the Escrow Agreement and the Note Documents
         have been, or will be, as applicable, duly executed and delivered by
         the Trustee and constitute, or will constitute, as applicable, the
         legal, valid and binding agreements of the Trustee, enforceable
         against it in accordance with their respective terms; provided,
         however, that enforceability may be limited by (i) applicable
         bankruptcy, insolvency, reorganization, moratorium or similar laws
         affecting the rights of creditors generally and (ii) general
         principles of equity.

                 Section 7.16.  Withholding Taxes; Information Reporting.  As

created by this Agreement, shall exclude and withhold from each distribution of
principal, premium, if any, and interest and other amounts due under this
Agreement or under the Certificates any and all withholding taxes applicable
thereto as required by law.  The Trustee agrees to act as such withholding
agent and, in connection therewith, whenever any present or future taxes or
similar charges are required to be withheld with respect to any amounts payable
in respect of
<PAGE>   57
                                       51

the Certificates, to withhold such amounts and timely pay the same to the
appropriate authority in the name of and on behalf of the Certificateholders,
that it will file any necessary withholding tax returns or statements when due,
and that, as promptly as possible after the payment thereof, it will deliver to
each such Certificateholder appropriate documentation showing the payment
thereof, together with such additional documentary evidence as such
Certificateholders may reasonably request from time to time.  The Trustee

capacity agrees that it will, in respect of each Trust created by this
Agreement, at its own cost and expense promptly take any action as may be
necessary to duly discharge and satisfy in full any mortgage, pledge, lien,
charge, encumbrance, security interest or claim ("Trustee's Liens") on or with
respect to the Trust Property of such Trust which is attributable to the
Trustee either (i) in its individual capacity and which is unrelated to the
transactions contemplated by this Agreement, the Intercreditor Agreement, the
Note Purchase Agreement or the Note Documents or (ii) as Trustee hereunder or
in its individual capacity and which arises out of acts or omissions which are
not contemplated by this Agreement.

                 Section 7.18.  Preferential Collection of Claims.  The Trustee

         and regulations, certificates or opinions of independent public
         accountants, conforming to the requirements of Section 1.02;

                 (c)      transmit to all Certificateholders, in the manner and

                 (e)      to comply with any requirement of the SEC, any
         applicable law, rules or regulations of any exchange or quotation
         system on which the Certificates are listed or of any regulatory body;
         or

                 (f)      to modify, eliminate or add to the provisions of this
         Agreement, the Intercreditor Agreement or any Liquidity Facility to
         such extent as shall be necessary to continue the qualification of
         this Agreement, the Intercreditor Agreement or any Liquidity Facility

                 Section 9.02.  Supplemental Agreements with Consent of
Certificateholders.  With respect to the Trust and the Certificates, with the
consent of the Certificateholders (including consents obtained in connection
with a tender offer or exchange offer for the Certificates) evidencing
Fractional Undivided Interests aggregating not less than a majority in interest
in such Trust, by Direction of said Certificateholders delivered to the Company
and the Trustee, the Company may (with the consent of the Owner Trustees, if
any, relating to the Certificates, which consent shall not be unreasonably
withheld), but shall not be obligated to, and the Trustee (subject to Section
9.03) shall, enter into an agreement or agreements supplemental hereto for the
purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Agreement, the Intercreditor Agreement, the
Escrow Agreement, the Deposit Agreement, the Note Purchase Agreement or any
Liquidity Facility to the extent applicable to such Certificateholders or of
modifying in any manner the rights and obligations of such Certificateholders
under this Agreement, the Intercreditor Agreement, the Escrow Agreement, the

provided, however, that no such agreement shall, without the consent of the

         timing of, any receipt by the Trustee of payments on the Equipment
         Notes held in such Trust or distributions that are required to be made
         herein on any Certificate, or change any date of payment on any
         Certificate, or change the place of payment where, or the coin or
         currency in which, any Certificate is payable, or impair the right to
         institute suit for the enforcement of any such payment or distribution
         on or after the Regular Distribution Date or Special Distribution Date
         applicable thereto; or

                 (b)      permit the disposition of any Equipment Note included
         in the Trust Property of such Trust except as permitted by this
         Agreement, or otherwise deprive such Certificateholder of the benefit
         of the ownership of the Equipment Notes in such Trust; or

                 (c)      alter the priority of distributions specified in the
         Intercreditor Agreement in a manner materially adverse to the
         interests of the Certificateholders; or

                 (d)      reduce the specified percentage of the aggregate
         Fractional Undivided Interests of such Trust that is required for any

         required for any waiver (of compliance with certain provisions of this
         Agreement or certain defaults hereunder and their consequences)
         provided for in this Agreement; or

                 (e)      modify any of the provisions of this Section 9.02 or
         Section 6.05, except to increase any such percentage or to provide

<PAGE>   62
                                       56

         this Agreement cannot be modified or waived without the consent of the
         Certificateholder of each Certificate affected thereby; or

                 (f)      adversely affect the status of any Trust as a grantor
         trust under Subpart E, Part I of Subchapter J of Chapter 1 of Subtitle
         A of the Internal Revenue Code of 1986, as amended, for U.S. federal
         income tax purposes.

                 It shall not be necessary for any Direction of such
Certificateholders under this Section 9.02 to approve the particular form of
any proposed supplemental agreement, but it shall be sufficient if such
Direction shall approve the substance thereof.

                 Section 9.03.  Documents Affecting Immunity or Indemnity.  If
in the opinion of the Trustee any document required to be executed by it
pursuant to the terms of Section 9.01 or 9.02 affects any interest, right,

Trust Supplement, the Trustee may in its discretion decline to execute such
document.

                 Section 9.04.  Execution of Supplemental Agreements.  In

created by this Agreement, the Trustee shall be entitled to receive, and shall
be fully protected in relying upon, an Opinion of Counsel stating that the
execution of such supplemental agreement is authorized or permitted by this
Agreement.

                 Section 9.05.  Effect of Supplemental Agreements.  Upon the
execution of any agreement supplemental to this Agreement under this Article,

supplemental agreement executed pursuant to this Article shall conform to the
requirements of the Trust Indenture Act as then in effect.

                 Section 9.07.  Reference in Certificates to Supplemental
Agreements.  Certificates authenticated and delivered after the execution of
any supplemental agreement  pursuant to this Article may bear a notation in
form approved by the Trustee as to any matter provided for in such supplemental
agreement; and, in such case, suitable notation may be made upon Outstanding
Certificates after proper presentation and demand.

                                   ARTICLE X

                   AMENDMENTS TO INDENTURE AND NOTE DOCUMENTS

                 Section 10.01.  Amendments and Supplements to Indenture and
Other Note Documents.  In the event that the Trustee, as holder (or beneficial
owner through the Subordination Agent) of any Equipment Notes (or as a
prospective purchaser of any Postponed Notes) in trust for the benefit of the
Certificateholders or as Controlling Party under an Intercreditor Agreement,
receives (directly or indirectly through the Subordination Agent) a request for
a consent to any amendment, modification, waiver or supplement under any
Indenture, other Note Document or any other related document, which request
would require the consent of Certificateholders under Section 9.02 hereof, the
Trustee shall forthwith send a notice of such proposed amendment, modification,
waiver or supplement to each Certificateholder registered on the Register as of
the date of such notice.  The Trustee shall request from the Certificateholders
a Direction as to (a) whether or not to take or refrain from taking (or direct
the Subordination Agent to take or refrain from taking) any action which a
holder of (or, with respect to Postponed Notes, a prospective purchaser of)
such Equipment Note or a Controlling Party has the option to direct, (b)
whether or not to give or execute (or direct the Subordination Agent to give or
execute) any waivers, consents, amendments, modifications or supplements as a
holder of (or, with respect to Postponed Notes, a prospective purchaser of)
such Equipment Note or as Controlling Party and (c) how to vote (or direct the
Subordination Agent to vote) any Equipment Note (or, with respect to a
Postponed Note, its commitment to acquire such Postponed Note) if a vote has
been called for with respect thereto.  Provided such a request for
Certificateholder Direction shall have been made, in directing any action or
casting any vote or giving any consent as the holder of any Equipment Note (or
in directing the Subordination Agent in any of the foregoing), (i) other than
as Controlling Party, the Trustee shall vote for or give consent to any such
action with respect to such Equipment Note (or Postponed Note) in the same
proportion as that of (A) the aggregate face amounts of all Certificates
actually voted in favor of or for giving consent to such action by such
Direction of Certificateholders to (B) the aggregate face amount of all
Outstanding Certificates and (ii) as Controlling Party, the Trustee shall vote
as directed in such Certificateholder Direction by the Certificateholders
evidencing a Fractional Undivided Interest aggregating not less than a majority
in interest in the Trust.  For purposes of the immediately preceding sentence,
a Certificate shall have been "actually voted" if the Holder of such
Certificate has delivered to the Trustee an instrument evidencing such Holder's
consent to such Direction prior to one Business Day before the Trustee directs
such action or casts such vote or gives such consent.  Notwithstanding the
foregoing, but subject to Section 6.04 and any Intercreditor Agreement, the
Trustee may, with respect to the Certificates, in its own discretion and at its
own direction, consent and notify the relevant Loan Trustee of such consent (or
direct the Subordination Agent to consent and notify the Loan Trustee of such
consent) to any amendment, modification, waiver or supplement under any related
Indenture or any other related Note Document if an Event of Default hereunder
<PAGE>   64
                                       58

shall have occurred and be continuing or if such amendment, modification,
waiver or supplement will not materially adversely affect the interests of the
Certificateholders.


                                   ARTICLE XI

                             TERMINATION OF TRUSTS

                 Section 11.01.  Termination of the Trust.  The respective
obligations and responsibilities of the Company and the Trustee shall terminate
upon the distribution to all Certificateholders and the Trustee of all amounts
required to be distributed to them pursuant to this Agreement and the
disposition of all property held as part of the Trust Property; provided,
however, that in no event shall the Trust continue beyond one hundred ten (110)
years following the date of the execution of this Agreement.

                 Notice of any termination, specifying the Distribution Date
upon which the Certificateholders may surrender their Certificates to the
Trustee for payment of the final distribution and cancellation, shall be mailed
promptly by the Trustee to Certificateholders not earlier than the 60th day and
not later than the 15th day next preceding such final Distribution Date
specifying (A) the Distribution Date upon which the proposed final payment of
the Certificates will be made upon presentation and surrender of Certificates
at the office or agency of the Trustee therein specified, (B) the amount of any
such proposed final payment, and (c) that the Record Date otherwise applicable
to such Distribution Date is not applicable, payments being made only upon
presentation and surrender of the Certificates at the office or agency of the
Trustee therein specified.  The Trustee shall give such notice to the Registrar
at the time such notice is given to Certificateholders.  Upon presentation and
surrender of the Certificates in accordance with such notice, the Trustee shall
cause to be distributed to Certificateholders such final payments.

                 In the event that all of the Certificateholders shall not
surrender their Certificates for cancellation within six months after the date
specified in the above-mentioned written notice, the Trustee shall give a
second written notice to the remaining Certificateholders to surrender their
Certificates for cancellation and receive the final distribution with respect
thereto.  No additional interest shall accrue on the Certificates after the
Distribution Date specified in the first written notice.  In the event that any
money held by the Trustee for the payment of distributions on the Certificates
shall remain unclaimed for two years (or such lesser time as the Trustee shall
be satisfied, after sixty days' notice from the Company, is one month prior to
the escheat period provided under applicable law) after the final distribution
date with respect thereto, the Trustee shall pay to each Loan Trustee the
appropriate amount of money relating to such Loan Trustee and shall give
written notice thereof to the related Owner Trustees, the Owner Participants
and the Company.

                            MISCELLANEOUS PROVISIONS

                 Section 12.01.  Limitation on Rights of Certificateholders.
The death or incapacity of any Certificateholder shall not operate to terminate
this Agreement or the Trust, nor entitle such Certificateholder's legal
representatives or heirs to claim an accounting or to take any action or
commence any proceeding in any court for a partition or winding up of the
Trust, nor otherwise affect the rights, obligations, and liabilities of the
parties hereto or any of them.

                 Section 12.02.  Liabilities of Certificateholders.  Neither
the existence of the Trust nor any provision in this Agreement is intended to
or shall limit the liability the Certificateholders would otherwise incur if
the Certificateholders owned Trust Property as co-owners, or incurred any
obligations of the Trust, directly rather than through the Trust.

                 Section 12.03.  Registration of Equipment Notes in Name of
Subordination Agent.  If the Trust is party to the Intercreditor Agreement, the
Trustee agrees that all Equipment Notes to be purchased by such Trust shall be
issued in the name of the Subordination Agent under the Intercreditor Agreement
or its nominee and held by such Subordination Agent in trust for the benefit of
the Certificateholders, or, if not so held, such Subordination Agent or its
nominee shall be reflected as the owner of such Equipment Notes in the register
of the issuer of such Equipment Notes.

                 Section 12.04.  Notices.  (a)  Unless otherwise specifically
provided herein, all notices required under the terms and provisions of this
Agreement shall be in English and in writing, and any such notice may be given
by United States mail, courier service or telecopy, and any such notice shall

                 (c)      Any notice or communication to Certificateholders
shall be mailed by first-class mail to the addresses for Certificateholders
shown on the Register kept by the Registrar and to addresses filed with the
Trustee for Certificate Owners.  Failure so to mail a notice or communication
or any defect in such notice or communication shall not affect its sufficiency
with respect to other Certificateholders or Certificate Owners.

                 Section 12.06.  Severability of Provisions.  If any one or
more of the covenants, agreements, provisions or terms of this Agreement shall
be for any reason whatsoever held invalid, then such covenants, agreements,
provisions, or terms shall be deemed severable from the remaining covenants,
agreements, provisions or terms of this Agreement and shall in no way affect
the validity or enforceability of the other provisions of

                                       61

this Agreement or the Trust, or of the Certificates or the rights of the
Certificateholders thereof.

                 Section 12.07.  Trust Indenture Act Controls.  Upon the
occurrence of any Registration Event, this Agreement shall become subject to

                 Section 12.11.  Legal Holidays.  In any case where any Regular

                 Section 12.14.  Intention of Parties.  The parties hereto
intend that each Trust be classified for U.S.  federal income tax purposes as a
grantor trust under Subpart E, Part I of Subchapter J of the Internal Revenue
Code of 1986, as amended, and not as a trust or association taxable as a
corporation or as a partnership.  The Trustee agrees to hold all assets of each
Trust for investment purposes only.  Each Certificateholder and Investor, by
its acceptance of its Certificate or a beneficial interest therein, agrees to
treat the Trust as a grantor trust for all U.S. federal, state and local income
tax purposes.  The powers granted and obligations undertaken pursuant to this
Agreement shall be so construed so as to further such intent.

be duly executed by their respective officers hereunto duly authorized as of
the day and year first written above.

Agreement, which provides for the Depositary to pay interest for distribution

                 NOW, THEREFORE, in consideration of the obligations contained
herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree
as follows:

                 SECTION 1.1  Acceptance of Depositary.  The Depositary hereby
agrees to act as depositary bank as provided herein and in connection therewith
to accept all amounts to be delivered to or held by the Depositary pursuant to
the terms of this Agreement.  The Depositary further agrees to hold, maintain
and safeguard the Deposits and the Accounts (as defined below) during the term
of this Agreement in accordance with the provisions of this Agreement.  The
Escrow Agent shall not have any right to withdraw, assign or otherwise transfer
moneys held in the Accounts except as permitted by this Agreement.

                 SECTION 1.2  Establishment of Accounts.  The Escrow Agent
hereby instructs the Depositary, and the Depositary agrees, to establish the
separate deposit accounts listed on Schedule I hereto and to establish such
additional separate deposit accounts as may be required in connection with the
deposits contemplated by Section 2.4 hereof (each, an "Account" and
collectively, the "Accounts"), each in the name of the Escrow Agent and all on
the terms and conditions set forth in this Agreement.

                 SECTION 2.1  Deposits.  The Escrow Agent shall direct the
Placement Agents to deposit with the Depositary on the date of this Agreement
(the "Deposit Date") in Federal (same day) funds by wire transfer to:  ABN AMRO
Bank N.V., Chicago Branch, Reference:  Atlas 1998-1, and the Depositary shall
accept from the Placement Agents, on behalf of the Escrow Agent, the sum of
US$300,254,000.  Upon acceptance of such sum, the Depositary shall (i)
establish each of the deposits specified in Schedule I hereto maturing on the
respective dates (each such date, as it may be extended from time to time in
accordance with the Indemnity Agreement, through the Delivery Period
Termination Date, a "Maturity


                                       2
<PAGE>   4
Date") set forth therein (including any deposit made pursuant to Section 2.4
hereof, individually, a "Deposit" and, collectively, the "Deposits") and (ii)
credit each Deposit to the related Account as set forth therein.  No amount
shall be deposited in any Account other than the related Deposit.

                 SECTION 2.2  Interest.  The Depositary shall pay interest on
each Deposit from and including the date of deposit to but excluding the
earlier of (x) the date of withdrawal and (y) the Maturity Date thereof at the
rate (the "Public Rate") of 7.38% per annum (computed on the basis of a year of
twelve 30-day months) payable to the Paying Agent on behalf of the Escrow Agent
semi-annually in arrears on each January 2 and July 2, and on the date of the
Final Withdrawal (as defined below), commencing on July 2, 1998 (each, an
"Interest Payment Date"), all in accordance with the terms of this Agreement
(whether or not any such Deposit is withdrawn on an Interest Payment Date);
provided, however, that in the event that no Registration Event (as defined in
the Registration Rights Agreement) occurs on or prior to the 180th day after
the date of the issuance of the Certificates (the "Registration Date"), the
interest rate per annum paid by the Depositary on each Deposit shall be
increased by 0.50%, effective from and including August 9, 1998, to but
excluding the date on which a Registration Event occurs; and provided, further,
that in the event that a Shelf Registration Statement (as defined in the
Registration Rights Agreement) ceases to be effective for more than 60 days,
whether or not consecutive, during any 12-month period at any time before the
earlier of (a) the second anniversary of the date hereof or (b) the sale
pursuant to the Shelf Registration Statement of all the Certificates covered
thereby, the interest rate per annum paid by the Depositary on each Deposit
shall be increased by 0.50% per annum from the 61st day of the applicable
12-month period such Shelf Registration Statement ceases to be effective until
such time as the Shelf Registration Statement again becomes effective.
Interest accrued on any Deposit that is withdrawn pursuant to a Notice of
Purchase Withdrawal (as defined below) shall be paid on the next Interest
Payment Date, notwithstanding any intervening Final Withdrawal (as defined
below).

                 SECTION 2.3  Withdrawals.  (a)  On and after the date seven
days after the establishment of any Deposit, the Escrow Agent may, by providing
at least one Business Day's prior notice of withdrawal to the Depositary in the
form of Exhibit A hereto (a "Notice of Purchase Withdrawal"), withdraw not less
than the entire balance of such Deposit, except that at any time prior to the
actual withdrawal of such Deposit, the Escrow Agent or the Pass Through Trustee
may, by notice to the Depositary, cancel such withdrawal (including on the
scheduled date therefor), and thereafter such Deposit shall continue to be
maintained by the Depositary in accordance with the original terms thereof.
Following such withdrawal the balance in the related Account shall be zero and
the Depositary shall close such Account.  As used herein, "Business Day" means
any day, other than a Saturday, Sunday or other day on which commercial banks
are authorized or required by law to close in New York, New York, Chicago,
Illinois, Denver, Colorado or Wilmington, Delaware.





                                       3
<PAGE>   5
                 (b)      The Escrow Agent may, by providing at least 15 days'
prior notice of withdrawal to the Depositary in the form of Exhibit B hereto (a
"Notice of Prepayment Withdrawal"), withdraw not less than the entire balance
of any Deposit together with all accrued and unpaid interest on such Deposit to
but excluding the specified date of withdrawal (a "Prepayment Withdrawal"), on
such date as shall be specified in such Notice of Prepayment Withdrawal.
Following such withdrawal the balance in the related Account shall be zero and
the Depositary shall close such Account.  Upon any Prepayment Withdrawal, the
Depositary shall (i) pay to the Paying Agent an amount equal to excess of the
aggregate amount of all Deposits on deposit immediately prior to such
Prepayment Withdrawal over the sum of the maximum principal amount of Equipment
Notes that may be acquired with funds withdrawn from all Deposits not being
withdrawn pursuant to such Notice of Prepayment Withdrawal and (ii) redeposit
the remainder, if any, of such Prepayment Withdrawal in accordance with Section
2.4 hereof.

                 (c)      The Escrow Agent may, by providing at least 15 days'
prior notice of withdrawal to the Depositary in the form of Exhibit C hereto (a
"Notice of Final Withdrawal"), withdraw the entire amount of all of the
remaining Deposits together with the all accrued and unpaid interest on such
Deposits to but excluding the specified date of withdrawal (a "Final
Withdrawal"), on such date as shall be specified in such Notice of Final
Withdrawal.  Following such withdrawal the balance in the related Accounts
shall be zero and the Depositary shall close such Accounts.  If a Notice of
Final Withdrawal has not been given to the Depositary on or before June 29,
1999 (provided, that if a labor strike or work stoppage occurs at The Boeing
Company prior to such date, such date shall be extended by adding thereto the
number of days that each such labor strike or work stoppage continues in effect
but in no event shall any such extension result in a Deposit being held by the
Depositary past such Deposit's then scheduled maturity date (subject to
extension pursuant to the Indemnity Agreement)) and there are unwithdrawn
Deposits on such date, the Depositary shall pay the amount of the Final
Withdrawal to the Paying Agent on the Delivery Period Termination Date.

                 (d)      If the Depositary receives a duly completed Notice of
Purchase Withdrawal, Notice of Prepayment Withdrawal or Notice of Final
Withdrawal complying with the provisions of this Agreement, it shall make the
payments specified therein in accordance with the provisions of this Agreement.

                 SECTION 2.4  Other Accounts.  On the date of withdrawal of any
Deposit, the Escrow Agent, or the Pass Through Trustee on behalf of the Escrow
Agent, shall be entitled to re-deposit with the Depositary any portion thereof
and the Depositary shall accept the same for deposit hereunder; provided,
however, that the Depositary shall have no obligation to accept such amounts
for deposit if Atlas, at or prior to such time, shall not have complied with
the provisions of Section 3(b) of the Indemnity Agreement.  Any sums so
received for deposit shall be established as a new Deposit and credited to a
new Account, all as more fully provided in Section 2.1 hereof, and thereafter
the provisions of this Agreement shall apply thereto as fully and with the same
force and effect as if such Deposit had been





                                       4
<PAGE>   6
established on the Deposit Date except that (i) such Deposit may not be
withdrawn prior to the date seven days after the establishment thereof and (ii)
such Deposit shall mature on December 30, 1998, as such date may be extended
from time to time in accordance with the Indemnity Agreement through the
Delivery Period Termination Date.

                 SECTION 2.5 Reset of Maturity Date.  If a Registration Event
has not occurred on the Registration Date, unless Atlas has complied with
Section 3(c) of the Indemnity Agreement, the Maturity Date for the Deposit then
held by the Depositary with respect to the final Aircraft to be delivered to
Atlas as contemplated by the Note Purchase Agreement shall be reset to the date
(the "Reset Date") that the Depositary reasonably determines to be the date on
which the sum of (x) interest accrued on the balances of all Deposits hereunder
from the date of calculation through the Reset Date at the then current Deposit
Rate plus (y) the balance of the Collateral Account as at such date of
calculation will be equal to the interest that will have accrued on the
Deposits hereunder from such date of calculation through the Reset Date at the
Public Rate (assuming all scheduled payments are made on each Interest Payment
Date occurring on or prior to the Reset Date and each then remaining Deposit is
withdrawn on its then scheduled Maturity Date). The Depositary shall use
reasonable efforts to determine the amounts necessary to determine the Reset
Date, and such determination shall be conclusive absent manifest error. Any
reset of such Maturity Date pursuant to this Section 2.5 shall be without
prejudice to Atlas' right to re-extend such Maturity Date by posting additional
collateral pursuant to Section 3(a) of the Indemnity Agreement.

                 SECTION 3.1  Termination.  This Agreement shall terminate on
the later of the date on which (i) all of the Deposits shall have been
withdrawn and paid as provided herein without any re-deposit and (ii) all
accrued and unpaid interest on the Deposits shall have been paid as provided
herein, but in no event prior to the date on which the Depositary shall have
performed in full its obligations hereunder.

                 SECTION 3.2  Substitute Depositary.  In the event that Atlas
is required under the provisions of Section 9 or Section 10 of the Indemnity
Agreement to make payments in a material amount to the Depositary, Atlas may
elect to terminate the Depositary as a party to this Agreement, the other
Deposit Agreements and the Indemnity Agreement; provided that, concurrently
with such termination, (i) Atlas shall pay the Depositary all amounts
(including, without limitation, amounts, if any, owed under such Section 9 and
Section 10) owed to the Depositary pursuant to any such Agreement through such
date of termination, (ii) another financial institution satisfactory to Atlas
and the Rating Agencies (as defined in the Note Purchase Agreement) shall
agree, as of such date, to assume all rights and obligations of the Depositary
under all such Agreements to be terminated as of such date, and (iii) all
documents and supporting materials necessary to evidence the termination of the
Depositary and the substitution of such other financial institution shall have
been received as of such date.

                 SECTION 4.  Payments.  All payments (including, without
limitation, those payments made in respect of Taxes (as defined and provided
for below)) made by the Depositary hereunder shall be paid in United States
Dollars and immediately available funds by wire transfer (i) in the case of
accrued interest on the Deposits payable under Section 2.2 hereof or any Final
Withdrawal, directly to the Paying Agent at Wilmington Trust Company,
Wilmington, Delaware, ABA# 03-11-000-92, Account No. 44043-0, Attention:
Robert Hines, Reference:  Atlas Air, or to such other account as the Paying
Agent may direct from time to time in writing to the Depositary and the Escrow
Agent and (ii) in the case of any withdrawal of one or more Deposits pursuant
to a Notice of Purchase Withdrawal, directly to or as directed by the Pass
Through Trustee as specified and in the manner provided in such Notice of
Purchase Withdrawal.  The Depositary hereby waives any and all rights of
set-off, combination of accounts, right of retention or similar right (whether
arising under applicable law, contract or otherwise) it may have against the
Deposits howsoever arising.  All payments on or in respect of each Deposit
shall be made free and clear of and without reduction for or on account of any
and all taxes, levies or other impositions or charges (collectively, "Taxes").
However, if the Depositary or the Paying Agent (pursuant to Section 2.04 of the
Escrow Agreement) shall be required by law to deduct or withhold any Taxes from
or in respect of any sum payable hereunder, the Depositary shall (i) make such
deductions or withholding, (ii) pay the full amount deducted or withheld
(including in respect of such additional amounts) to the competent taxation
authority and (iii) if the Taxes required to be deducted or withheld are
imposed by the Netherlands or any political subdivision thereof, pay such
additional amounts as may be necessary in order that the actual amount received
by the designated recipient of such sum under this Agreement or the Escrow
Agreement after such deduction or withholding equals the sum it would have
received had no such deduction or withholding been required.  If the date on
which any payment due on any Deposit would otherwise fall on a day which is not
a Business Day, such payment shall be made on the next succeeding Business Day,
and no additional interest shall accrue in respect of such extension.

                 SECTION 5.  Representation and Warranties.  The Depositary
hereby represents and warrants to Atlas, the Escrow Agent, the Pass Through
Trustee and the Paying Agent that:

                 (a)      it is a bank duly organized and validly existing in
         good standing under the laws of the Netherlands and is duly qualified
         to conduct banking business in the State of Illinois through its
         Chicago Branch;

                 (b)      it has full power, authority and legal right to
         conduct its business and operations as currently conducted and to
         enter into and perform its obligations under this Agreement;

                 (c)      the execution, delivery and performance of this
         Agreement have been duly authorized by all necessary corporate action
         on the part of it and do not require any stockholder approval, or
         approval or consent of any trustee or holder of any





                                       6
<PAGE>   8
         indebtedness or obligations of it, and such document has been duly
         executed and delivered by it and constitutes its legal, valid and
         binding obligations enforceable against it in accordance with the
         terms hereof;

                 (d)      no authorization, consent or approval of or other
         action by, and no notice to or filing with, any United States federal
         or state governmental authority or regulatory body is required for the
         execution, delivery or performance by it of this Agreement;

                 (e)      neither the execution, delivery or performance by it
         of this Agreement, nor compliance with the terms and provisions
         hereof, conflicts or will conflict with or results or will result in a
         breach or violation of any of the terms, conditions or provisions of,
         or will require any consent or approval under, any law, governmental
         rule or regulation or the charter documents, as amended, or bylaws, as
         amended, of it or any similar instrument binding on it or any order,
         writ, injunction or decree of any court or governmental authority
         against it or by which it or any of its properties is bound or any
         indenture, mortgage or contract or other agreement or instrument to
         which it is a party or by which it or any of its properties is bound,
         or constitutes or will constitute a default thereunder or results or
         will result in the imposition of any lien upon any of its properties;

                 (f)      there are no pending or, to its knowledge, threatened
         actions, suits, investigations or proceedings (whether or not
         purportedly on behalf of it) against or affecting it or any of its
         property before or by any court or administrative agency which, if
         adversely determined, (i) would adversely affect the ability of it to
         perform its obligations under this Agreement or (ii) would call into
         question or challenge the validity of this Agreement or the
         enforceability hereof in accordance with the terms hereof, nor is the
         Depositary in default with respect to any order of any court,
         governmental authority, arbitration board or administrative agency so
         as to adversely affect its ability to perform its obligations under
         this Agreement; and

                 (g)      the Depositary will make all payments under this
         Agreement from its own funds and not from funds provided by, or on
         deposit from, Atlas or any of its subsidiaries.

                 SECTION 6.  Transfer.  Neither party hereto shall be entitled
to assign or otherwise transfer this Agreement (or any interest herein) other
than (in the case of the Escrow Agent) to a successor escrow agent under the
Escrow Agreement, and any purported assignment in violation thereof shall be
void.  This Agreement shall be binding upon the parties hereto and their
respective successors and (in the case of the Escrow Agent) permitted assigns.
Upon the occurrence of the Transfer (as defined below) contemplated by the
Assignment and Assumption Agreement (as defined below), the Pass Through
Trustee shall (without further act) be deemed to have transferred all of its
right, title and interest in and to this Agreement to the trustee of the
Successor Trust (as defined below) and, thereafter, the





                                       7
<PAGE>   9
trustee of the Successor Trust shall be deemed to be the "Pass Through Trustee"
hereunder with the rights of the "Pass Through Trustee" hereunder, and each
reference herein to "Atlas Air, Inc. Pass Through Trust 1998-1A-O" shall be
deemed to be a reference to "Atlas Air Inc. Pass Through Trust 1998-1A-S".  The
Escrow Agent and the Depositary hereby acknowledge and consent to the Transfer
contemplated by the Assignment and Assumption Agreement.  For the purposes of
this Section 6, "Transfer" means the transfer contemplated by the Assignment
and Assumption Agreement; "Assignment and Assumption Agreement" means the
Assignment and Assumption Agreement to be entered into between the Pass Through
Trustee and the trustee of the Successor Trust, substantially in the form of
Exhibit E to the Pass Through Trust Agreement; and "Successor Trust" means the
Atlas Air, Inc. Pass Through Trust 1998-1A-S.

                 SECTION 7.  Amendment, Etc.  This Agreement may not be
amended, waived or otherwise modified except by an instrument in writing signed

to accept all amounts to be delivered to or held by the Depositary pursuant to
the terms of this Agreement.  The Depositary further agrees to hold, maintain
and safeguard the Deposits and the Accounts (as defined below) during the term
of this Agreement in accordance with the provisions of this Agreement.  The
Escrow Agent shall not have any right to withdraw, assign or otherwise transfer
moneys held in the Accounts except as permitted by this Agreement.

                 SECTION 1.2  Establishment of Accounts.  The Escrow Agent
hereby instructs the Depositary, and the Depositary agrees, to establish the
separate deposit accounts listed on Schedule I hereto and to establish such
additional separate deposit accounts as may be required in connection with the
deposits contemplated by Section 2.4 hereof (each, an "Account" and
collectively, the "Accounts"), each in the name of the Escrow Agent and all on
the terms and conditions set forth in this Agreement.

                 SECTION 2.1  Deposits.  The Escrow Agent shall direct the
Placement Agents to deposit with the Depositary on the date of this Agreement
(the "Deposit Date") in Federal (same day) funds by wire transfer to:  ABN AMRO
Bank N.V., Chicago Branch, Reference:  Atlas 1998-1, and the Depositary shall
accept from the Placement Agents, on behalf of the Escrow Agent, the sum of
US$115,481,000.  Upon acceptance of such sum, the Depositary shall (i)
establish each of the deposits specified in Schedule I hereto maturing on the
respective dates (each such date, as it may be extended from time to time in
accordance with the Indemnity Agreement, through the Delivery Period
Termination Date, a "Maturity




                                      2

Date") set forth therein (including any deposit made pursuant to Section 2.4
hereof, individually, a "Deposit" and, collectively, the "Deposits") and (ii)
credit each Deposit to the related Account as set forth therein.  No amount
shall be deposited in any Account other than the related Deposit.

                 SECTION 2.2  Interest.  The Depositary shall pay interest on
each Deposit from and including the date of deposit to but excluding the
earlier of (x) the date of withdrawal and (y) the Maturity Date thereof at the
rate (the "Public Rate") of 7.68% per annum (computed on the basis of a year of
twelve 30-day months) payable to the Paying Agent on behalf of the Escrow Agent
semi-annually in arrears on each January 2 and July 2, and on the date of the
Final Withdrawal (as defined below), commencing on July 2, 1998 (each, an
"Interest Payment Date"), all in accordance with the terms of this Agreement
(whether or not any such Deposit is withdrawn on an Interest Payment Date);
provided, however, that in the event that no Registration Event (as defined in
the Registration Rights Agreement) occurs on or prior to the 180th day after
the date of the issuance of the Certificates (the "Registration Date"), the
interest rate per annum paid by the Depositary on each Deposit shall be
increased by 0.50%, effective from and including August 9, 1998, to but
excluding the date on which a Registration Event occurs; and provided, further,
that in the event that a Shelf Registration Statement (as defined in the
Registration Rights Agreement) ceases to be effective for more than 60 days,
whether or not consecutive, during any 12-month period at any time before the
earlier of (a) the second anniversary of the date hereof or (b) the sale
pursuant to the Shelf Registration Statement of all the Certificates covered
thereby, the interest rate per annum paid by the Depositary on each Deposit
shall be increased by 0.50% per annum from the 61st day of the applicable
12-month period such Shelf Registration Statement ceases to be effective until
such time as the Shelf Registration Statement again becomes effective.
Interest accrued on any Deposit that is withdrawn pursuant to a Notice of
Purchase Withdrawal (as defined below) shall be paid on the next Interest
Payment Date, notwithstanding any intervening Final Withdrawal (as defined
below).

                 SECTION 2.3  Withdrawals.  (a)  On and after the date seven
days after the establishment of any Deposit, the Escrow Agent may, by providing
at least one Business Day's prior notice of withdrawal to the Depositary in the
form of Exhibit A hereto (a "Notice of Purchase Withdrawal"), withdraw not less
than the entire balance of such Deposit, except that at any time prior to the
actual withdrawal of such Deposit, the Escrow Agent or the Pass Through Trustee
may, by notice to the Depositary, cancel such withdrawal (including on the
scheduled date therefor), and thereafter such Deposit shall continue to be
maintained by the Depositary in accordance with the original terms thereof.
Following such withdrawal the balance in the related Account shall be zero and
the Depositary shall close such Account.  As used herein, "Business Day" means
any day, other than a Saturday, Sunday or other day on which commercial banks
are authorized or required by law to close in New York, New York, Chicago,
Illinois, Denver, Colorado or Wilmington, Delaware.

<PAGE>   5
                 (b)      The Escrow Agent may, by providing at least 15 days'
prior notice of withdrawal to the Depositary in the form of Exhibit B hereto (a
"Notice of Prepayment Withdrawal"), withdraw not less than the entire balance
of any Deposit together with all accrued and unpaid interest on such Deposit to
but excluding the specified date of withdrawal (a "Prepayment Withdrawal"), on
such date as shall be specified in such Notice of Prepayment Withdrawal.
Following such withdrawal the balance in the related Account shall be zero and
the Depositary shall close such Account.  Upon any Prepayment Withdrawal, the
Depositary shall (i) pay to the Paying Agent an amount equal to excess of the
aggregate amount of all Deposits on deposit immediately prior to such
Prepayment Withdrawal over the sum of the maximum principal amount of Equipment
Notes that may be acquired with funds withdrawn from all Deposits not being
withdrawn pursuant to such Notice of Prepayment Withdrawal and (ii) redeposit
the remainder, if any, of such Prepayment Withdrawal in accordance with Section
2.4 hereof.

                 (c)      The Escrow Agent may, by providing at least 15 days'
prior notice of withdrawal to the Depositary in the form of Exhibit C hereto (a
"Notice of Final Withdrawal"), withdraw the entire amount of all of the
remaining Deposits together with the all accrued and unpaid interest on such
Deposits to but excluding the specified date of withdrawal (a "Final
Withdrawal"), on such date as shall be specified in such Notice of Final
Withdrawal.  Following such withdrawal the balance in the related Accounts
shall be zero and the Depositary shall close such Accounts.  If a Notice of
Final Withdrawal has not been given to the Depositary on or before June 29,
1999 (provided, that if a labor strike or work stoppage occurs at The Boeing
Company prior to such date, such date shall be extended by adding thereto the
number of days that each such labor strike or work stoppage continues in effect
but in no event shall any such extension result in a Deposit being held by the
Depositary past such Deposit's then scheduled maturity date (subject to
extension pursuant to the Indemnity Agreement)) and there are unwithdrawn
Deposits on such date, the Depositary shall pay the amount of the Final
Withdrawal to the Paying Agent on the Delivery Period Termination Date.

                 (d)      If the Depositary receives a duly completed Notice of
Purchase Withdrawal, Notice of Prepayment Withdrawal or Notice of Final
Withdrawal complying with the provisions of this Agreement, it shall make the
payments specified therein in accordance with the provisions of this Agreement.

                 SECTION 2.4  Other Accounts.  On the date of withdrawal of any
Deposit, the Escrow Agent, or the Pass Through Trustee on behalf of the Escrow
Agent, shall be entitled to re-deposit with the Depositary any portion thereof
and the Depositary shall accept the same for deposit hereunder; provided,
however, that the Depositary shall have no obligation to accept such amounts
for deposit if Atlas, at or prior to such time, shall not have complied with
the provisions of Section 3(b) of the Indemnity Agreement.  Any sums so
received for deposit shall be established as a new Deposit and credited to a
new Account, all as more fully provided in Section 2.1 hereof, and thereafter
the provisions of this Agreement shall apply thereto as fully and with the same
force and effect as if such Deposit had been





                                      4
<PAGE>   6
established on the Deposit Date except that (i) such Deposit may not be
withdrawn prior to the date seven days after the establishment thereof and (ii)
such Deposit shall mature on December 30, 1998, as such date may be extended
from time to time in accordance with the Indemnity Agreement through the
Delivery Period Termination Date.

                 SECTION 2.5 Reset of Maturity Date.  If a Registration Event
has not occurred on the Registration Date, unless Atlas has complied with
Section 3(c) of the Indemnity Agreement, the Maturity Date for the Deposit then
held by the Depositary with respect to the final Aircraft to be delivered to
Atlas as contemplated by the Note Purchase Agreement shall be reset to the date
(the "Reset Date") that the Depositary reasonably determines to be the date on
which the sum of (x) interest accrued on the balances of all Deposits hereunder
from the date of calculation through the Reset Date at the then current Deposit
Rate plus (y) the balance of the Collateral Account as at such date of
calculation will be equal to the interest that will have accrued on the
Deposits hereunder from such date of calculation through the Reset Date at the
Public Rate (assuming all scheduled payments are made on each Interest Payment
Date occurring on or prior to the Reset Date and each then remaining Deposit is
withdrawn on its then scheduled Maturity Date). The Depositary shall use
reasonable efforts to determine the amounts necessary to determine the Reset
Date, and such determination shall be conclusive absent manifest error. Any
reset of such Maturity Date pursuant to this Section 2.5 shall be without
prejudice to Atlas' right to re-extend such Maturity Date by posting additional
collateral pursuant to Section 3(a) of the Indemnity Agreement.

                 SECTION 3.1  Termination.  This Agreement shall terminate on
the later of the date on which (i) all of the Deposits shall have been
withdrawn and paid as provided herein without any re-deposit and (ii) all
accrued and unpaid interest on the Deposits shall have been paid as provided
herein, but in no event prior to the date on which the Depositary shall have
performed in full its obligations hereunder.

                 SECTION 3.2  Substitute Depositary.  In the event that Atlas
is required under the provisions of Section 9 or Section 10 of the Indemnity
Agreement to make payments in a material amount to the Depositary, Atlas may
elect to terminate the Depositary as a party to this Agreement, the other
Deposit Agreements and the Indemnity Agreement; provided that, concurrently
with such termination, (i) Atlas shall pay the Depositary all amounts
(including, without limitation, amounts, if any, owed under such Section 9 and
Section 10) owed to the Depositary pursuant to any such Agreement through such
date of termination, (ii) another financial institution satisfactory to Atlas
and the Rating Agencies (as defined in the Note Purchase Agreement) shall
agree, as of such date, to assume all rights and obligations of the Depositary
under all such Agreements to be terminated as of such date, and (iii) all
documents and supporting materials necessary to evidence the termination of the
Depositary and the substitution of such other financial institution shall have
been received as of such date.

<PAGE>   7
                 SECTION 4.  Payments.  All payments (including, without
limitation, those payments made in respect of Taxes (as defined and provided
for below)) made by the Depositary hereunder shall be paid in United States
Dollars and immediately available funds by wire transfer (i) in the case of
accrued interest on the Deposits payable under Section 2.2 hereof or any Final
Withdrawal, directly to the Paying Agent at Wilmington Trust Company,
Wilmington, Delaware, ABA# 03-11-000-92, Account No. 44043-0, Attention:
Robert Hines, Reference:  Atlas Air, or to such other account as the Paying
Agent may direct from time to time in writing to the Depositary and the Escrow
Agent and (ii) in the case of any withdrawal of one or more Deposits pursuant
to a Notice of Purchase Withdrawal, directly to or as directed by the Pass
Through Trustee as specified and in the manner provided in such Notice of
Purchase Withdrawal.  The Depositary hereby waives any and all rights of
set-off, combination of accounts, right of retention or similar right (whether
arising under applicable law, contract or otherwise) it may have against the
Deposits howsoever arising.  All payments on or in respect of each Deposit
shall be made free and clear of and without reduction for or on account of any
and all taxes, levies or other impositions or charges (collectively, "Taxes").
However, if the Depositary or the Paying Agent (pursuant to Section 2.04 of the
Escrow Agreement) shall be required by law to deduct or withhold any Taxes from
or in respect of any sum payable hereunder, the Depositary shall (i) make such
deductions or withholding, (ii) pay the full amount deducted or withheld
(including in respect of such additional amounts) to the competent taxation
authority and (iii) if the Taxes required to be deducted or withheld are
imposed by the Netherlands or any political subdivision thereof, pay such
additional amounts as may be necessary in order that the actual amount received
by the designated recipient of such sum under this Agreement or the Escrow
Agreement after such deduction or withholding equals the sum it would have
received had no such deduction or withholding been required.  If the date on
which any payment due on any Deposit would otherwise fall on a day which is not
a Business Day, such payment shall be made on the next succeeding Business Day,
and no additional interest shall accrue in respect of such extension.

                 SECTION 5.  Representation and Warranties.  The Depositary
hereby represents and warrants to Atlas, the Escrow Agent, the Pass Through
Trustee and the Paying Agent that:

                 (a)      it is a bank duly organized and validly existing in
         good standing under the laws of the Netherlands and is duly qualified
         to conduct banking business in the State of Illinois through its
         Chicago Branch;

                 (b)      it has full power, authority and legal right to
         conduct its business and operations as currently conducted and to
         enter into and perform its obligations under this Agreement;

                 (c)      the execution, delivery and performance of this
         Agreement have been duly authorized by all necessary corporate action
         on the part of it and do not require any stockholder approval, or
         approval or consent of any trustee or holder of any





                                      6
<PAGE>   8
         indebtedness or obligations of it, and such document has been duly
         executed and delivered by it and constitutes its legal, valid and
         binding obligations enforceable against it in accordance with the
         terms hereof;

                 (d)      no authorization, consent or approval of or other
         action by, and no notice to or filing with, any United States federal
         or state governmental authority or regulatory body is required for the
         execution, delivery or performance by it of this Agreement;

                 (e)      neither the execution, delivery or performance by it
         of this Agreement, nor compliance with the terms and provisions
         hereof, conflicts or will conflict with or results or will result in a
         breach or violation of any of the terms, conditions or provisions of,
         or will require any consent or approval under, any law, governmental
         rule or regulation or the charter documents, as amended, or bylaws, as
         amended, of it or any similar instrument binding on it or any order,
         writ, injunction or decree of any court or governmental authority
         against it or by which it or any of its properties is bound or any
         indenture, mortgage or contract or other agreement or instrument to
         which it is a party or by which it or any of its properties is bound,
         or constitutes or will constitute a default thereunder or results or
         will result in the imposition of any lien upon any of its properties;

                 (f)      there are no pending or, to its knowledge, threatened
         actions, suits, investigations or proceedings (whether or not
         purportedly on behalf of it) against or affecting it or any of its
         property before or by any court or administrative agency which, if
         adversely determined, (i) would adversely affect the ability of it to
         perform its obligations under this Agreement or (ii) would call into
         question or challenge the validity of this Agreement or the
         enforceability hereof in accordance with the terms hereof, nor is the
         Depositary in default with respect to any order of any court,
         governmental authority, arbitration board or administrative agency so
         as to adversely affect its ability to perform its obligations under
         this Agreement; and

                 (g)      the Depositary will make all payments under this
         Agreement from its own funds and not from funds provided by, or on
         deposit from, Atlas or any of its subsidiaries.

                 SECTION 6.  Transfer.  Neither party hereto shall be entitled
to assign or otherwise transfer this Agreement (or any interest herein) other
than (in the case of the Escrow Agent) to a successor escrow agent under the
Escrow Agreement, and any purported assignment in violation thereof shall be
void.  This Agreement shall be binding upon the parties hereto and their
respective successors and (in the case of the Escrow Agent) permitted assigns.
Upon the occurrence of the Transfer (as defined below) contemplated by the
Assignment and Assumption Agreement (as defined below), the Pass Through
Trustee shall (without further act) be deemed to have transferred all of its
right, title and interest in and to this Agreement to the trustee of the
Successor Trust (as defined below) and, thereafter, the

hereunder with the rights of the "Pass Through Trustee" hereunder, and each
reference herein to "Atlas Air, Inc. Pass Through Trust 1998-1B-O" shall be
deemed to be a reference to "Atlas Air Inc. Pass Through Trust 1998-1B-S".  The
Escrow Agent and the Depositary hereby acknowledge and consent to the Transfer
contemplated by the Assignment and Assumption Agreement.  For the purposes of
this Section 6, "Transfer" means the transfer contemplated by the Assignment
and Assumption Agreement; "Assignment and Assumption Agreement" means the
Assignment and Assumption Agreement to be entered into between the Pass Through
Trustee and the trustee of the Successor Trust, substantially in the form of
Exhibit E to the Pass Through Trust Agreement; and "Successor Trust" means the
Atlas Air, Inc. Pass Through Trust 1998-1B-S.

                 SECTION 7.  Amendment, Etc.  This Agreement may not be
amended, waived or otherwise modified except by an instrument in writing signed
by the party against whom the amendment, waiver or other modification is sought
to be enforced and by the Pass Through Trustee.

                 SECTION 8.  Notices.  Unless otherwise expressly specified or
permitted by the terms hereof, all notices, requests, demands, authorizations,

                 SECTION 11.  Governing Law.  This Agreement, and the rights
and obligations of the Depositary and the Escrow Agent with respect to the
Deposits, shall be governed by, and construed in accordance with, the laws of
the State of New York and subject to the provisions of Regulation D of the

Agreement, which provides for the Depositary to pay interest for distribution

                 NOW, THEREFORE, in consideration of the obligations contained
herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree
as follows:

                 SECTION 1.1  Acceptance of Depositary.  The Depositary hereby
agrees to act as depositary bank as provided herein and in connection therewith
to accept all amounts to be delivered to or held by the Depositary pursuant to
the terms of this Agreement.  The Depositary further agrees to hold, maintain
and safeguard the Deposits and the Accounts (as defined below) during the term
of this Agreement in accordance with the provisions of this Agreement.  The
Escrow Agent shall not have any right to withdraw, assign or otherwise transfer
moneys held in the Accounts except as permitted by this Agreement.

                 SECTION 1.2  Establishment of Accounts.  The Escrow Agent
hereby instructs the Depositary, and the Depositary agrees, to establish the
separate deposit accounts listed on Schedule I hereto and to establish such
additional separate deposit accounts as may be required in connection with the
deposits contemplated by Section 2.4 hereof (each, an "Account" and
collectively, the "Accounts"), each in the name of the Escrow Agent and all on
the terms and conditions set forth in this Agreement.

                 SECTION 2.1  Deposits.  The Escrow Agent shall direct the
Placement Agents to deposit with the Depositary on the date of this Agreement
(the "Deposit Date") in Federal (same day) funds by wire transfer to:  ABN AMRO
Bank N.V., Chicago Branch, Reference:  Atlas 1998-1, and the Depositary shall
accept from the Placement Agents, on behalf of the Escrow Agent, the sum of
US$123,180,000.  Upon acceptance of such sum, the Depositary shall (i)
establish each of the deposits specified in Schedule I hereto maturing on the
respective dates (each such date, as it may be extended from time to time in
accordance with the Indemnity Agreement, through the Delivery Period
Termination Date, a "Maturity




                                      2
<PAGE>   4
Date") set forth therein (including any deposit made pursuant to Section 2.4
hereof, individually, a "Deposit" and, collectively, the "Deposits") and (ii)
credit each Deposit to the related Account as set forth therein.  No amount
shall be deposited in any Account other than the related Deposit.

                 SECTION 2.2  Interest.  The Depositary shall pay interest on
each Deposit from and including the date of deposit to but excluding the
earlier of (x) the date of withdrawal and (y) the Maturity Date thereof at the
rate (the "Public Rate") of 8.01% per annum (computed on the basis of a year of
twelve 30-day months) payable to the Paying Agent on behalf of the Escrow Agent
semi-annually in arrears on each January 2 and July 2, and on the date of the
Final Withdrawal (as defined below), commencing on July 2, 1998 (each, an
"Interest Payment Date"), all in accordance with the terms of this Agreement
(whether or not any such Deposit is withdrawn on an Interest Payment Date);
provided, however, that in the event that no Registration Event (as defined in
the Registration Rights Agreement) occurs on or prior to the 180th day after
the date of the issuance of the Certificates (the "Registration Date"), the
interest rate per annum paid by the Depositary on each Deposit shall be
increased by 0.50%, effective from and including August 9, 1998, to but
excluding the date on which a Registration Event occurs; and provided, further,
that in the event that a Shelf Registration Statement (as defined in the
Registration Rights Agreement) ceases to be effective for more than 60 days,
whether or not consecutive, during any 12-month period at any time before the
earlier of (a) the second anniversary of the date hereof or (b) the sale
pursuant to the Shelf Registration Statement of all the Certificates covered
thereby, the interest rate per annum paid by the Depositary on each Deposit
shall be increased by 0.50% per annum from the 61st day of the applicable
12-month period such Shelf Registration Statement ceases to be effective until
such time as the Shelf Registration Statement again becomes effective.
Interest accrued on any Deposit that is withdrawn pursuant to a Notice of
Purchase Withdrawal (as defined below) shall be paid on the next Interest
Payment Date, notwithstanding any intervening Final Withdrawal (as defined
below).

                 SECTION 2.3  Withdrawals.  (a)  On and after the date seven
days after the establishment of any Deposit, the Escrow Agent may, by providing
at least one Business Day's prior notice of withdrawal to the Depositary in the
form of Exhibit A hereto (a "Notice of Purchase Withdrawal"), withdraw not less
than the entire balance of such Deposit, except that at any time prior to the
actual withdrawal of such Deposit, the Escrow Agent or the Pass Through Trustee
may, by notice to the Depositary, cancel such withdrawal (including on the
scheduled date therefor), and thereafter such Deposit shall continue to be
maintained by the Depositary in accordance with the original terms thereof.
Following such withdrawal the balance in the related Account shall be zero and
the Depositary shall close such Account.  As used herein, "Business Day" means
any day, other than a Saturday, Sunday or other day on which commercial banks
are authorized or required by law to close in New York, New York, Chicago,
Illinois, Denver, Colorado or Wilmington, Delaware.





                                      3
<PAGE>   5
                 (b)      The Escrow Agent may, by providing at least 15 days'
prior notice of withdrawal to the Depositary in the form of Exhibit B hereto (a
"Notice of Prepayment Withdrawal"), withdraw not less than the entire balance
of any Deposit together with all accrued and unpaid interest on such Deposit to
but excluding the specified date of withdrawal (a "Prepayment Withdrawal"), on
such date as shall be specified in such Notice of Prepayment Withdrawal.
Following such withdrawal the balance in the related Account shall be zero and
the Depositary shall close such Account.  Upon any Prepayment Withdrawal, the
Depositary shall (i) pay to the Paying Agent an amount equal to excess of the
aggregate amount of all Deposits on deposit immediately prior to such
Prepayment Withdrawal over the sum of the maximum principal amount of Equipment
Notes that may be acquired with funds withdrawn from all Deposits not being
withdrawn pursuant to such Notice of Prepayment Withdrawal and (ii) redeposit
the remainder, if any, of such Prepayment Withdrawal in accordance with Section
2.4 hereof.

                 (c)      The Escrow Agent may, by providing at least 15 days'
prior notice of withdrawal to the Depositary in the form of Exhibit C hereto (a
"Notice of Final Withdrawal"), withdraw the entire amount of all of the
remaining Deposits together with the all accrued and unpaid interest on such
Deposits to but excluding the specified date of withdrawal (a "Final
Withdrawal"), on such date as shall be specified in such Notice of Final
Withdrawal.  Following such withdrawal the balance in the related Accounts
shall be zero and the Depositary shall close such Accounts.  If a Notice of
Final Withdrawal has not been given to the Depositary on or before June 29,
1999 (provided, that if a labor strike or work stoppage occurs at The Boeing
Company prior to such date, such date shall be extended by adding thereto the
number of days that each such labor strike or work stoppage continues in effect
but in no event shall any such extension result in a Deposity being held by the
Depositary past such Deposit's then scheduled maturity date (subject to
extension pursuant to the Indemnity Agreement)) and there are unwithdrawn
Deposits on such date, the Depositary shall pay the amount of the Final
Withdrawal to the Paying Agent on the Delivery Period Termination Date.

                 (d)      If the Depositary receives a duly completed Notice of
Purchase Withdrawal, Notice of Prepayment Withdrawal or Notice of Final
Withdrawal complying with the provisions of this Agreement, it shall make the
payments specified therein in accordance with the provisions of this Agreement.

                 SECTION 2.4  Other Accounts.  On the date of withdrawal of any
Deposit, the Escrow Agent, or the Pass Through Trustee on behalf of the Escrow
Agent, shall be entitled to re-deposit with the Depositary any portion thereof
and the Depositary shall accept the same for deposit hereunder; provided,
however, that the Depositary shall have no obligation to accept such amounts
for deposit if Atlas, at or prior to such time, shall not have complied with
the provisions of Section 3(b) of the Indemnity Agreement.  Any sums so
received for deposit shall be established as a new Deposit and credited to a
new Account, all as more fully provided in Section 2.1 hereof, and thereafter
the provisions of this Agreement shall apply thereto as fully and with the same
force and effect as if such Deposit had been





                                      4
<PAGE>   6
established on the Deposit Date except that (i) such Deposit may not be
withdrawn prior to the date seven days after the establishment thereof and (ii)
such Deposit shall mature on December 30, 1998, as such date may be extended
from time to time in accordance with the Indemnity Agreement through the
Delivery Period Termination Date.

                 SECTION 2.5 Reset of Maturity Date.  If a Registration Event
has not occurred on the Registration Date, unless Atlas has complied with
Section 3(c) of the Indemnity Agreement, the Maturity Date for the Deposit then
held by the Depositary with respect to the final Aircraft to be delivered to
Atlas as contemplated by the Note Purchase Agreement shall be reset to the date
(the "Reset Date") that the Depositary reasonably determines to be the date on
which the sum of (x) interest accrued on the balances of all Deposits hereunder
from the date of calculation through the Reset Date at the then current Deposit
Rate plus (y) the balance of the Collateral Account as at such date of
calculation will be equal to the interest that will have accrued on the
Deposits hereunder from such date of calculation through the Reset Date at the
Public Rate (assuming all scheduled payments are made on each Interest Payment
Date occurring on or prior to the Reset Date and each then remaining Deposit is
withdrawn on its then scheduled Maturity Date). The Depositary shall use
reasonable efforts to determine the amounts necessary to determine the Reset
Date, and such determination shall be conclusive absent manifest error. Any
reset of such Maturity Date pursuant to this Section 2.5 shall be without
prejudice to Atlas' right to re-extend such Maturity Date by posting additional
collateral pursuant to Section 3(a) of the Indemnity Agreement.

                 SECTION 3.1  Termination.  This Agreement shall terminate on
the later of the date on which (i) all of the Deposits shall have been
withdrawn and paid as provided herein without any re-deposit and (ii) all
accrued and unpaid interest on the Deposits shall have been paid as provided
herein, but in no event prior to the date on which the Depositary shall have
performed in full its obligations hereunder.

                 SECTION 3.2  Substitute Depositary.  In the event that Atlas
is required under the provisions of Section 9 or Section 10 of the Indemnity
Agreement to make payments in a material amount to the Depositary, Atlas may
elect to terminate the Depositary as a party to this Agreement, the other
Deposit Agreements and the Indemnity Agreement; provided that, concurrently
with such termination, (i) Atlas shall pay the Depositary all amounts
(including, without limitation, amounts, if any, owed under such Section 9 and
Section 10) owed to the Depositary pursuant to any such Agreement through such
date of termination, (ii) another financial institution satisfactory to Atlas
and the Rating Agencies (as defined in the Note Purchase Agreement) shall
agree, as of such date, to assume all rights and obligations of the Depositary
under all such Agreements to be terminated as of such date, and (iii) all
documents and supporting materials necessary to evidence the termination of the
Depositary and the substitution of such other financial institution shall have

                 SECTION 4.  Payments.  All payments (including, without
limitation, those payments made in respect of Taxes (as defined and provided
for below)) made by the Depositary hereunder shall be paid in United States
Dollars and immediately available funds by wire transfer (i) in the case of
accrued interest on the Deposits payable under Section 2.2 hereof or any Final
Withdrawal, directly to the Paying Agent at Wilmington Trust Company,
Wilmington, Delaware, ABA# 03-11-000-92, Account No. 44043-0, Attention:
Robert Hines, Reference:  Atlas Air, or to such other account as the Paying
Agent may direct from time to time in writing to the Depositary and the Escrow
Agent and (ii) in the case of any withdrawal of one or more Deposits pursuant
to a Notice of Purchase Withdrawal, directly to or as directed by the Pass
Through Trustee as specified and in the manner provided in such Notice of
Purchase Withdrawal.  The Depositary hereby waives any and all rights of
set-off, combination of accounts, right of retention or similar right (whether
arising under applicable law, contract or otherwise) it may have against the
Deposits howsoever arising.  All payments on or in respect of each Deposit
shall be made free and clear of and without reduction for or on account of any
and all taxes, levies or other impositions or charges (collectively, "Taxes").
However, if the Depositary or the Paying Agent (pursuant to Section 2.04 of the
Escrow Agreement) shall be required by law to deduct or withhold any Taxes from
or in respect of any sum payable hereunder, the Depositary shall (i) make such
deductions or withholding, (ii) pay the full amount deducted or withheld
(including in respect of such additional amounts) to the competent taxation
authority and (iii) if the Taxes required to be deducted or withheld are
imposed by the Netherlands or any political subdivision thereof, pay such
additional amounts as may be necessary in order that the actual amount received
by the designated recipient of such sum under this Agreement or the Escrow
Agreement after such deduction or withholding equals the sum it would have
received had no such deduction or withholding been required.  If the date on
which any payment due on any Deposit would otherwise fall on a day which is not
a Business Day, such payment shall be made on the next succeeding Business Day,
and no additional interest shall accrue in respect of such extension.

                 SECTION 5.  Representation and Warranties.  The Depositary
hereby represents and warrants to Atlas, the Escrow Agent, the Pass Through
Trustee and the Paying Agent that:

                 (a)      it is a bank duly organized and validly existing in
         good standing under the laws of the Netherlands and is duly qualified
         to conduct banking business in the State of Illinois through its
         Chicago Branch;

                 (b)      it has full power, authority and legal right to
         conduct its business and operations as currently conducted and to
         enter into and perform its obligations under this Agreement;

                 (c)      the execution, delivery and performance of this
         Agreement have been duly authorized by all necessary corporate action
         on the part of it and do not require any stockholder approval, or
         approval or consent of any trustee or holder of any





                                      6

         indebtedness or obligations of it, and such document has been duly
         executed and delivered by it and constitutes its legal, valid and
         binding obligations enforceable against it in accordance with the
         terms hereof;

                 (d)      no authorization, consent or approval of or other
         action by, and no notice to or filing with, any United States federal
         or state governmental authority or regulatory body is required for the
         execution, delivery or performance by it of this Agreement;

                 (e)      neither the execution, delivery or performance by it
         of this Agreement, nor compliance with the terms and provisions
         hereof, conflicts or will conflict with or results or will result in a
         breach or violation of any of the terms, conditions or provisions of,
         or will require any consent or approval under, any law, governmental
         rule or regulation or the charter documents, as amended, or bylaws, as
         amended, of it or any similar instrument binding on it or any order,
         writ, injunction or decree of any court or governmental authority
         against it or by which it or any of its properties is bound or any
         indenture, mortgage or contract or other agreement or instrument to
         which it is a party or by which it or any of its properties is bound,
         or constitutes or will constitute a default thereunder or results or
         will result in the imposition of any lien upon any of its properties;

                 (f)      there are no pending or, to its knowledge, threatened
         actions, suits, investigations or proceedings (whether or not
         purportedly on behalf of it) against or affecting it or any of its
         property before or by any court or administrative agency which, if
         adversely determined, (i) would adversely affect the ability of it to
         perform its obligations under this Agreement or (ii) would call into
         question or challenge the validity of this Agreement or the
         enforceability hereof in accordance with the terms hereof, nor is the
         Depositary in default with respect to any order of any court,
         governmental authority, arbitration board or administrative agency so
         as to adversely affect its ability to perform its obligations under
         this Agreement; and

                 (g)      the Depositary will make all payments under this
         Agreement from its own funds and not from funds provided by, or on
         deposit from, Atlas or any of its subsidiaries.

                 SECTION 6.  Transfer.  Neither party hereto shall be entitled
to assign or otherwise transfer this Agreement (or any interest herein) other
than (in the case of the Escrow Agent) to a successor escrow agent under the
Escrow Agreement, and any purported assignment in violation thereof shall be
void.  This Agreement shall be binding upon the parties hereto and their
respective successors and (in the case of the Escrow Agent) permitted assigns.
Upon the occurrence of the Transfer (as defined below) contemplated by the
Assignment and Assumption Agreement (as defined below), the Pass Through
Trustee shall (without further act) be deemed to have transferred all of its
right, title and interest in and to this Agreement to the trustee of the
Successor Trust (as defined below) and, thereafter, the

Escrow Agent and the Depositary hereby acknowledge and consent to the Transfer
contemplated by the Assignment and Assumption Agreement.  For the purposes of
this Section 6, "Transfer" means the transfer contemplated by the Assignment
and Assumption Agreement; "Assignment and Assumption Agreement" means the
Assignment and Assumption Agreement to be entered into between the Pass Through
Trustee and the trustee of the Successor Trust, substantially in the form of
Exhibit E to the Pass Through Trust Agreement; and "Successor Trust" means the

                 SECTION 7.  Amendment, Etc.  This Agreement may not be
amended, waived or otherwise modified except by an instrument in writing signed
by the party against whom the amendment, waiver or other modification is sought

                              INDEMNITY AGREEMENT

                 INDEMNITY AGREEMENT dated as of February 9, 1998 (as amended,
modified or supplemented from time to time, this "Agreement") between ABN AMRO
BANK N.V., a banking institution organized under the laws of the Netherlands,
acting through its Chicago Branch ("ABN AMRO", and in its capacity as
depositary bank under the Deposit Agreements referred to below (together with
its successors and assigns in such capacity), the "Depositary"), and ATLAS AIR,
INC., a Delaware corporation (together with its successors and assigns,
"Atlas").


                               W I T N E S S E T H


                 WHEREAS, in connection with the financing by Atlas of the
Aircraft set forth on Schedule I hereto, First Security Bank, National
Association, as escrow agent (in such capacity together with its successors in
such capacity, the "Escrow Agent"), and the Depositary are entering into the
Deposit Agreements set forth on Schedule II hereto (as amended, modified or
supplemented from time to time in accordance with the terms thereof and with
the consent of Atlas, the "Deposit Agreements") pursuant to each of which,
among other things, (i) the Depositary will establish accounts into and from
which the Escrow Agent shall make deposits, withdrawals and re-deposits and
(ii) the Depositary will pay the Escrow Agent interest at the Coupon Rate on
the amounts on deposit in each such account (such amounts, the "Deposits");

                 WHEREAS, on the date hereof, the Escrow Agent shall deposit
(i) $300,254,000 with the Depositary under the Class A Deposit Agreement (the
"Initial Class A Deposit Amount"), (ii) $115,481,000 with the Depositary under
the Class B Deposit Agreement (the "Initial Class B Deposit Amount") and (iii)
$123,180,000 with the Depositary under the Class C Deposit Agreement (the
"Initial Class C Deposit Amount" and, together with the Initial Class A Deposit
Amount and the Initial Class B Deposit Amount, the "Initial Deposit Amounts");
and

                 WHEREAS, it is a condition precedent to the obligation of the
Depositary to enter into the Deposit Agreements that Atlas enter into this
Indemnity Agreement;

                 NOW, THEREFORE, in consideration of the Depositary entering
into the Deposit Agreements and the mutual agreements herein contained and
other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties hereto agree as follows (capitalized terms not
defined herein shall have the meanings set forth in Annex A hereto):

                                       2

                 SECTION 1.  Indemnity Payments.

                 (a)  On each Interest Payment Date, Atlas shall pay to ABN
AMRO the amount, if any, by which (x) the sum of all payments to be made by the
Depositary to the Escrow Agent pursuant to the Deposit Agreements on such
Interest Payment Date (including any amounts resulting from an increase in the
applicable Coupon Rate in accordance with Section 2.2 of the Deposit
Agreements) exceeds (y) the sum of interest which has accrued on each Deposit
at the rate set forth on Schedule II hereto under the heading "Deposit Interest
Rate" (the "Deposit Interest Rate") from and including the Interest Payment
Date immediately preceding such Interest Payment Date (or, in the case of the
initial Interest Payment Date, from and including the date of this Agreement)
to but excluding such Interest Payment Date.

                 (b)  In the event that any new Deposit is established pursuant
to Section 2.4 of the Deposit Agreement (a "New Deposit"), on each Interest
Payment Date subsequent to the date of establishment of such New Deposit, Atlas
shall pay to ABN AMRO the amount, if any, by which (x) the payment to be made
by the Depositary to the Escrow Agent with respect to such New Deposit pursuant
to the relevant Deposit Agreement (including any amounts resulting from an
increase in the applicable Coupon Rate in accordance with Section 2.2 of the
Deposit Agreements) exceeds (y) the interest which has accrued on such New
Deposit at the rate established by ABN AMRO as the deposit interest rate with
respect thereto (the "New Deposit Interest Rate") from and including the
Interest Payment Date immediately preceding such Interest Payment Date (or, in
the case of the first Interest Payment Date following the date of establishment
of such New Deposit, from and including such date of establishment) to but
excluding such Interest Payment Date.

                 SECTION 2.  Collateral Account and Investments.

                 (a)  Collateral Account.  There is hereby established with ABN
AMRO a collateral account (the "Collateral Account") in the name and under the
control of ABN AMRO into which Atlas shall deposit cash from time to time in
accordance with the provisions of Section 2(b) and Section 3 hereof.  The
balance from time to time in the Collateral Account shall be subject to
withdrawal only as provided herein.

                 (b)  Initial Collateral Account Deposit.  On the date hereof,
Atlas shall deposit into the Collateral Account the amount set forth on
Schedule II hereto under the heading "Initial Collateral Deposit", representing
the aggregate of (1) the amount by which (x) the sum of all payments to be made
by the Depositary to the Escrow Agent pursuant to the Deposit Agreements
exceeds (y) the sum of interest accruing at the Deposit Interest Rate on each
Deposit from and including the date of establishment thereof to but excluding
the Maturity Date thereof and (2) the Overdue Amount, reasonably estimated by
ABN AMRO,
<PAGE>   6
                                       3

that would accrue and become payable by Atlas to ABN AMRO pursuant to Section
5(b) of this Agreement as a result of the occurrence of the events described in
such Section.

                 (c)  Investment of Balance in Collateral Account.  Amounts on
deposit in the Collateral Account shall be invested from time to time in
Permitted Investments at the direction of Atlas; provided, that if Atlas shall
fail to provide instructions with respect to the investment of any amounts in
the Collateral Account not then invested in Permitted Investments at or before
12:00 noon Chicago time on any day such amounts are to be invested, ABN AMRO
shall invest such amounts in Permitted Investments with a duration of one day.
Such Permitted Investments shall be held in the name and be under the control
of ABN AMRO.

                 (d)  Pledge.  As collateral security for the prompt payment in
full when due of Atlas' obligations under this Agreement (but with respect to
Atlas' obligation to pay Breakage Obligations (as defined below) pursuant to
Section 4 hereof, only to the extent that the amounts on deposit in the
Breakage Account (as defined below) and pledged in accordance with Section 4(c)
hereof are insufficient to cover amounts due and payable pursuant to such
Section 4) (the "Secured Obligations"), Atlas hereby pledges and grants to ABN
AMRO a security interest in all of Atlas' right, title and interest in and to
the Collateral Account, the amounts on deposit therein, the funds therein, the
balance thereof and all proceeds of the foregoing (collectively, the
"Collateral").  If at any time Atlas shall fail to pay any Secured Obligation
when due, ABN AMRO may (in its sole discretion) (i) liquidate any investments
made in respect of amounts deposited in the Collateral Account and (ii) apply
or cause to be applied the balance from time to time outstanding to the credit
of the Collateral Account to the payment of such Secured Obligation.

                 In addition, with respect to the Collateral, ABN AMRO shall be
entitled to all rights and remedies available to a secured party under the
Uniform Commercial Code as in effect in any applicable jurisdiction and such
additional rights and remedies to which a secured party is entitled under the
laws in effect in any jurisdiction where any rights and remedies hereunder may
be asserted. Atlas hereby appoints ABN AMRO as its attorney-in-fact, with full
power of substitution, so that, if Atlas shall fail to pay any Secured
Obligation or Breakage Obligation when due, ABN AMRO may take such action and
execute such agreements, instruments and documents with respect to the
Collateral, in the name of Atlas, as ABN AMRO may deem necessary or desirable
for ABN AMRO to exercise its rights and remedies hereunder, or to enforce
Atlas' obligations hereunder or to perfect ABN AMRO's security interest granted
hereunder, which appointment is coupled with an interest and is irrevovable.
The proceeds of any sale of Collateral or any setoff of the Collateral against
the Secured Obligations and Breakage Obligations shall be applied (i) first, to
all reasonable expenses (including, without limitation, fees and expenses of
legal counsel) or taxes imposed or incurred in connection with the custody,
care, sale or collection, or realization upon, any of the Collateral or the
preservation or enforcement of any rights of  ABN AMRO
<PAGE>   7
                                       4

hereunder, and (ii) second, to the payment of the Secured Obligations. To the
extent any such application of the proceeds of the Collateral is insufficient
to cover all such expenses and Secured Obligations and Breakage Obligations,
Atlas shall be liable for such insufficiency.

                 (e)  On each Interest Payment Date, if at the time the
Depositary has made the payments of interest scheduled to be made on such
Interest Payment Date pursuant to the Deposit Agreements, Atlas has not
otherwise paid to ABN AMRO all sums due and payable on such Interest Payment
date pursuant to Section 1(a) (and, if any New Deposit has been established,
Section 1(b)) hereof, ABN AMRO shall withdraw and apply to Atlas' obligations
to make payments under such Sections an amount in the Collateral Account equal
to the aggregate amount then due and payable pursuant thereto.

                 (f)  Atlas may, from time to time and so long as it is not in
default of any of its obligations pursuant hereto, request that ABN AMRO
withdraw from the Collateral Account and release to Atlas any unreleased
Investment Earnings therein.  Within five Business Days of delivery of such
request, ABN AMRO shall pay such amounts to Atlas in immediately available
funds.

                 (g)  Upon the later of:

                          (i)     the later of (x) the date on which all of the
                                  Deposits shall have been withdrawn and paid
                                  (or shall be required to be withdrawn and
                                  paid) as provided in the Deposit Agreements
                                  without any redeposit and (y) the date on
                                  which all accrued and unpaid interest on the
                                  Deposits shall have been paid (or shall have
                                  become due and payable) as provided in the
                                  Deposit Agreement (the later of clause (x)
                                  and (y) being referred to as the "Deposit
                                  Agreement Termination Date") and

                          (ii)    the payment in full of all Secured
                                  Obligations due and payable on or prior to
                                  the Deposit Agreement Termination Date (the
                                  "Termination Date"),

ABN AMRO shall pay all amounts in the Collateral Account, together with any
unreleased Investment Earnings thereon, to Atlas as promptly as is practicable
and in immediately available funds.

                 SECTION 3.  Increases in Collateral Account.

                 (a)  Delayed Delivery; Extension of Maturity Dates.

                 (i)      With respect to any particular Aircraft (or
         Substitute Aircraft in respect thereof) that will not be delivered and
         in respect of which Equipment Notes will not be issued pursuant to the
         Note Purchase Agreement on or prior to the last Business Day of such
         Aircraft's Scheduled Delivery Month, Atlas may extend the Maturity
         Date of any Deposits maturing within such Scheduled Delivery Month by
         delivering to ABN AMRO at least 15 days prior to such Maturity Date a
         notice (an "Extension Notice") specifying a date prior to the Delivery
         Period Termination Date to which such Maturity Date is to be extended
         (such date, the "Rescheduled Maturity Date").  Upon receipt of the
         Extension Notice, ABN AMRO shall establish, and promptly deliver to
         Atlas notice of, the deposit interest rate (the "Extension Rate") that
         shall apply to such Deposits for the period from and including their
         original Maturity Date to but excluding their Rescheduled Maturity
         Date (such period, the "Extension Period").  Upon the original
         Maturity Date of any Deposit with respect to which ABN AMRO has
         received an Extension Notice, the maturity of such Deposit shall be
         deemed extended to the Rescheduled Maturity Date without the need for
         any action on the part of the Escrow Agent or the Depositary;
         provided, however, that Atlas may exercise no such right of extension,
         and such Maturity Dates shall not be extended in accordance with this
         Section 3(a)(i), if Atlas shall not have deposited into the Collateral
         Account on or prior to the relevant original Maturity Date an amount
         (such amount, the "Delay Increase Amount") equal to the excess, if
         any, of (x) the aggregate interest accruing on such Deposits pursuant
         to the Deposit Agreements during the Extension Period over (y) the
         aggregate interest accruing on such Deposits at the Extension Rate
         during the Extension Period.

                 (ii)     Nothing in Section 3(a)(i) above shall be interpreted
         to prevent Atlas from further extending any Maturity Dates previously
         extended in accordance therewith; provided, however, that in no event
         shall Atlas be able to extend any Maturity Date beyond the Delivery
         Period Termination Date.  In the event of any such further extensions,
         any references in such Section to a "Maturity Date" or "original
         Maturity Date" shall be deemed to refer to the most recently
         established Rescheduled Maturity Date with respect to the relevant
         Deposits and any references in such Section to a "Rescheduled Maturity
         Date" shall be deemed to refer to the date of maturity of such
         Deposits as to be further extended.
<PAGE>   9
                                       6

                 (b)  Re-deposits.  In the event that any New Deposit is
established, Atlas shall, on the date of the establishment thereof, deposit
into the Collateral Account the amount by which (x) the sum of all payments to
be made by the Depositary to the Escrow Agent with respect to such new Deposit
pursuant to the relevant Deposit Agreement exceeds (y) the sum of interest
accruing on such new Deposit at the New Deposit Interest Rate with respect
thereto from and including the date of establishment of such New Deposit to but
excluding the Maturity Date thereof.

                 (c)  Interest Step-up.  If no Registration Event has occurred
30 days prior to the Registration Date, or in the event of any increase in the
Coupon Rate of any Deposit pursuant to Section 2.2 of the Deposit Agreements,
Atlas shall, on the applicable date, deposit into the Collateral Account an
amount equal to the aggregate additional interest that would accrue on all
Deposits then extant as a result of such increase from and including the date
of such increase to but excluding the Delivery Period Termination Date.  Upon
the cessation of such increase, ABN AMRO shall pay to Atlas as promptly as is
practicable and in immediately available funds an amount equal to the excess,
if any, of (x) the amount deposited by Atlas into the Collateral Account
pursuant to this Section 3(c) over (y) the aggregate additional interest that
actually accrued on the Deposits from and including the date of such increase
to but excluding the date of the cessation thereof, together with any
unreleased Investment Earnings thereon.

                 (d)  Breakage Gross-Up.  In the event that ABN AMRO exercises
its rights under Section 2(d) hereof with respect to any amounts due and
payable pursuant to Section 4 hereof, Atlas shall upon demand by ABN AMRO
deposit into the Collateral Account an amount equal to the amount withdrawn
from the Collateral Account in accordance with such Section 2(d) within 5 days
of such demand or, if an Interest Payment shall occur before the lapse of such
5-day period, on or before such Interest Payment Date.

                 SECTION 4.  Breakage Account; Breakage Costs.

                 (a)  Breakage Account.  There is hereby established with ABN
AMRO a collateral account (the "Breakage Account") in the name and under the
control of ABN AMRO into which Atlas shall deposit cash from time to time in
accordance with the provisions of  this Section 4.  The balance from time to
time in the Breakage Account shall be subject to withdrawal only as provided
herein.

                 (b)  Investment of Balance in Breakage Account.  Amounts on
deposit in the Breakage Account shall be invested from time to time in
Permitted Investments at the direction of Atlas; provided, that if Atlas shall
fail to provide instructions with respect to the investment of any amounts in
the Breakage Account not then invested in Permitted Investments at or before
12:00 noon Chicago time on any day such amounts are to be invested, ABN AMRO
shall invest such amounts in Permitted Investments with a duration of
<PAGE>   10
                                       7

one day.  Such Permitted Investments shall be held in the name and be under the
control of ABN AMRO.

                 (c)  Pledge.  As collateral security for the prompt payment in
full when due of Atlas' obligations under this Section 4 (the "Breakage
Obligations"), Atlas hereby pledges and grants to ABN AMRO a security interest
in all of Atlas' right, title and interest in and to the Breakage Account and
the amounts on deposit therein.  If at any time Atlas shall fail to pay any
Breakage Obligation when due, ABN AMRO may (in its sole discretion) (i)
liquidate any investments made in respect of amounts deposited in the Breakage
Account and (ii) apply or cause to be applied the balance from time to time
outstanding to the credit of the Breakage Account to the payment of such
Breakage Obligation.

                 (d)  Breakage.  Atlas shall compensate ABN AMRO for any
reasonable losses, costs or expenses (including, without limitation, any cost
of funding or loss as a result of terminating, liquidating, obtaining or re-
establishing any hedge or related trading position) (such losses, costs or
expenses, "Breakage Costs") actually incurred as the result of (w) the
withdrawal of any Deposit prior to the Maturity Date thereof or (x) the
cancellation of any withdrawal with respect to which a notice has been
delivered to the Depositary pursuant to Section 2.3(a) of the Deposit Agreement
less than one Business Day prior to the scheduled date of such withdrawal (such
withdrawal, termination, reset or (y) the termination of any Deposit Agreement
pursuant to Section 3.2 thereof or (z) the reset of our Maturity Date (and/or
the withdrawal of a Deposit on such reset Maturity Date) pursuant to Section
2.5 of any Deposit Agreement or cancellation, a "Breakage Event").  Atlas shall
pay ABN AMRO an amount equal to the excess of any Breakage Costs actually
incurred over any such costs recovered in accordance with Section 4(e) below
within 5 days of demand by ABN AMRO of such payment.  Together with such
demand, ABN AMRO shall deliver to Atlas a certificate setting forth in
reasonable detail such Breakage Costs and any amounts that ABN AMRO is entitled
to receive pursuant to this Section 4(d) and shall be prima facie evidence of
such amounts.

                 (e)  Anticipated Breakage Cost.

                          (i)  Without limiting the generality of the foregoing
         Section 4(d), if at any time Applicable LIBOR shall be equal to or
         greater than a rate per annum fifty basis points below the Blended
         Coupon Rate, ABN AMRO may deliver to Atlas notice of the Breakage
         Costs that ABN AMRO would incur with respect to each Deposit then
         still extant (such notice an "Anticipated Breakage Notice" and the
         date thereof a "Notice Date") from and including the relevant Notice
         Date to but excluding the Maturity Date of each such Deposit if a
         Breakage Event were to occur as of such Notice Date.  Within 5 days of
         receipt of an Anticipated Breakage Notice, Atlas shall deposit into
         the Breakage Account an amount (the "Anticipated Breakage Cost") equal
         to:
<PAGE>   11
                                       8


                 (A)      the aggregate amount of the Deposits, multiplied by

                 (B)      a rate per annum equal to the excess of Applicable
                          LIBOR over a rate seventy-five basis points below the
                          Blended Coupon Rate, multiplied by

                 (C)      the quotient of a number equal to the remaining
                          weighted average life of the Deposits in days divided
                          by 360.

         Such deposit shall be net of any amounts to be released to Atlas in
         accordance with Section 4(e)(iii) hereof.

                          (ii)  Upon the occurrence of a Breakage Event, ABN
         AMRO shall withdraw from the Breakage Account and apply to Atlas'
         obligation to pay Breakage Costs pursuant to this Section 4 an amount
         equal to the lesser of such Breakage Costs and the Anticipated
         Breakage Costs, if any, then on deposit in the Breakage Account.

                          (iii)  At any time that the amount on deposit in the
         Breakage Account (such amount, from time to time, the "Breakage
         Balance") exceed the Anticipated Breakage Costs that ABN AMRO would
         incur with respect to each Deposit extant on such date, Atlas may
         request the withdrawal and release of an amount equal to the excess of
         all amounts deposited and not previously released over such
         Anticipated Breakage Costs, together with any unreleased Investment
         Earnings on such excess.  ABN AMRO shall release such amounts to Atlas
         within 5 days of receipt of such request.

                 (f)  Upon the later of:

                          (i)     the Deposit Agreement Termination Date and

                          (ii)    the payment in full of all Breakage
                                  Obligations due and payable on or prior to
                                  the Deposit Agreement Termination Date,

ABN AMRO shall forthwith pay all amounts in the Breakage Account, together with
any unreleased Investment Earnings thereon, to Atlas.

                 SECTION 5.  Overdue Amounts.  (a)  Atlas agrees to pay to ABN
AMRO interest on any amount that shall not be paid by Atlas when due under this
Agreement (an "Overdue Amount") at the Overdue Interest Rate, calculated on the
basis of a year of 360 days and actual days elapsed; provided, however, that no
such interest shall accrue on Overdue Amounts to the extent that ABN AMRO may
in accordance with the provisions of
<PAGE>   12
                                       9

this Agreement, and does not, withdraw and apply in payment thereof amounts on
deposit in the Collateral Account or the Breakage Account, as the case may be.
Such interest shall accrue on the portion of any Overdue Amount remaining
unpaid from time to time, from and including (or, in the case of amounts due
pursuant to Sections 1(a) and 1(b) hereof, from but excluding) the date that
such Overdue Amount is not paid when due to but excluding the date that it is
paid in full.  Overdue Amounts shall be payable on demand by ABN AMRO.

                 (b)  Without limiting the generality of the foregoing, amounts
on deposit in the Collateral Account or the Breakage Account which ABN AMRO
would be entitled to withdraw and apply in accordance with Section 1(e) or
Section 4(e)(ii) hereof, but which ABN AMRO cannot so withdraw and apply due to
the operation of the "automatic stay" provisions of the United States
Bankruptcy Code, shall be deemed Overdue Amounts from and including the date as
of which such provisions are in effect to but excluding the date on which ABN
AMRO is permitted to apply and withdraw them.

                 SECTION 6.  Representations and Warranties.  (A)  Atlas
represents and warrants to ABN AMRO that:

                 (a)      Atlas is a corporation duly incorporated, validly
         existing and in good standing under the Laws of the State of Delaware
         and has the corporate power and authority to conduct the business in
         which it is currently engaged and to own or hold under lease its
         properties and to enter into and perform its obligations under this
         Agreement.  Atlas is duly qualified to do business as a foreign
         corporation in good standing in each jurisdiction in which the nature
         and extent of the business conducted by it, or the ownership of its
         properties, requires such qualification except where the failure to be
         so qualified would not reasonably be expected to give rise to a
         Material Adverse Change to Atlas.

                 (b)      Atlas has taken, or caused to be taken, all necessary
         corporate action (including, without limitation, the obtaining of any
         consent or approval of stockholders required by its Certificate of
         Incorporation or By-Laws) to authorize the execution and delivery of
         this Agreement, and the performance of its obligations hereunder.

                 (c)      The execution and delivery by Atlas of this
         Agreement, the performance by Atlas of its obligations hereunder and
         the consummation by Atlas of the transactions contemplated hereby, do
         not and will not (i) violate any provision of the Certificate of
         Incorporation or By-Laws of Atlas, (ii) violate any Law applicable to
         or binding on Atlas, or (iii) violate or constitute any default under
         (other than any violation or default that would not reasonably be
         expected to result in a Material Adverse Change to Atlas), or result
         in the creation of any Lien (other than as permitted under any lease
         and other than the Liens contemplated hereby) upon any of
<PAGE>   13
                                       10

         the collateral hereunder under, any indenture, mortgage, chattel
         mortgage, deed of trust, conditional sales contract, lease, loan or
         other material agreement, instrument or document to which Atlas is a
         party or by which Atlas or any of its properties is bound or affected.

                 (d)      The execution and delivery by Atlas of this
         Agreement, the performance by Atlas of its obligations hereunder and
         the consummation by Atlas of the transactions contemplated hereby do
         not and will not require the consent or approval of, or the giving of
         notice to, or the registration with, or the recording or filing of any
         documents with, or the taking of any other action in respect of, (i)
         any trustee or other holder of any debt of Atlas and (ii) any
         Government Entity, other than filings, recordings, notices or other
         ministerial actions pursuant to any routine recording, contractual or
         regulatory requirements applicable to it.

                 (e)      This Agreement has been duly authorized, executed and
         delivered by Atlas and, assuming the due authorization, execution and
         delivery thereof by the other party hereto, constitutes the legal,
         valid and binding obligations of Atlas and is enforceable against
         Atlas in accordance with the terms hereof, except as such
         enforceability may be limited by bankruptcy, insolvency,
         reorganization, receivership, moratorium and other similar Laws
         affecting the rights of creditors generally and general principles of
         equity, whether considered in a proceeding at law or in equity and
         except as rights to indemnification may be limited by federal or state
         securities laws or principles of public policy.

                 (f)      Except as set forth in Atlas' most recent Annual
         Report on Form 10-K, as amended, filed by Atlas with the SEC on or
         prior to the date hereof, or in any Quarterly Report on Form 10-Q or
         Current Report on Form 8-K filed by Atlas with the SEC subsequent to
         such Annual Report on Form 10-K and on or prior to the date hereof, no
         action, claim or proceeding is now pending or, to the Actual Knowledge
         of Atlas threatened, against Atlas before any court, governmental
         body, arbitration, board, tribunal or administrative agency, which is
         reasonably likely to be determined adversely to Atlas and if
         determined adversely to Atlas would reasonably be expected to result
         in a Material Adverse Change with respect to Atlas.

                 (g)       The audited consolidated balance sheet of Atlas with
         respect to Atlas' most recent fiscal year included in Atlas' most
         recent Annual Report on Form 10-K, as amended, filed by Atlas with the
         SEC, and the related consolidated statements of operations and cash
         flows for that period then ended have been prepared in accordance with
         GAAP and fairly present in all material respects the financial
         condition of Atlas and its consolidated subsidiaries as of such date
         and the results of its operations and cash flows for such period, and
         since the date of such balance sheet there has been no material
         adverse change in such financial condition or operations of
<PAGE>   14
                                       11

         Atlas, except for matters disclosed in (a) the financial statements or
         Annual Report on Form 10-K referred to above, (b) any subsequent
         Quarterly Report on Form 10-Q or Current Report on Form 8-K filed by
         Atlas with the SEC on or prior to the date hereof or (c) the Offering
         Memorandum dated January 27, 1998 relating to the Atlas Air, Inc. Pass
         Through Certificates, Series 1998-1.

                 (h)      This Agreement creates a security interest in favor
         of ABN AMRO in the Collateral Account, the Breakage Account, the
         Collateral and the Breakage Balance and such security interest
         constitutes a first priority perfected security interest in favor of
         ABN AMRO.

                 (i)      There are no financing statements under the Uniform
         Commercial Code or similar law of any state or jurisdiction affecting
         any property, right or interests of Atlas in the Collateral Account,
         the Breakage Account, the Collateral or the Breakage Balance.

                 (j)      On each occasion on which Atlas delivers amounts to
         the Breakage Account or Collateral Account hereunder, Atlas shall be
         the owner of such collateral or other amounts and has the right to
         receive all payments on such collateral, in each case fee and clear of
         all liens and security interest other than the lien and security
         interest under this Agreement. Atlas further covenants that it will
         not create, permit or suffer to be created any other lien or security
         interest in the Collateral Account, the Breakage Account, the
         Collateral or the Breakage Balance.

                 (B)      ABN AMRO represents and warrants to Atlas that:

                 (a)      ABN AMRO is a banking institution duly organized,
         validly existing and in good standing under the Laws of the
         Netherlands and is duly qualified to conduct banking business in the
         State of Illinois through its Chicago Branch and has the corporate
         power and authority to enter into and perform its obligations under
         this Agreement.

                 (b)      ABN AMRO has taken, or caused to be taken, all
         necessary corporate action (including, without limitation, the
         obtaining of any consent or approval of stockholders required by its
         Certificate of Incorporation or By-Laws) to authorize the execution
         and delivery of this Agreement, and the performance of its obligations
         hereunder.

                 (c)      The execution and delivery by ABN AMRO of this
         Agreement, the performance by ABN AMRO of its obligations hereunder
         and the consummation by ABN AMRO of the transactions contemplated
         hereby, do not and will not (i) violate
<PAGE>   15
                                       12

         any provision of the Certificate of Incorporation or By-Laws of ABN
         AMRO or (ii) violate any Law applicable to or binding on ABN AMRO.

                 (d)      The execution and delivery by ABN AMRO of this
         Agreement, the performance by ABN AMRO of its obligations hereunder
         and the consummation by ABN AMRO of the transactions contemplated
         hereby do not and will not require the consent or approval of, or the
         giving of notice to, or the registration with, or the recording or
         filing of any documents with, or the taking of any other action in
         respect of, (i) any trustee or other holder of any debt of ABN AMRO
         and (ii) any Government Entity, other than filings, recordings,
         notices or other ministerial actions pursuant to any routine
         recording, contractual or regulatory requirements applicable to it.

                 (e)      This Agreement has been duly authorized, executed and
         delivered by ABN AMRO and, assuming the due authorization, execution
         and delivery thereof by the other party hereto, constitutes the legal,
         valid and binding obligations of ABN AMRO and is enforceable against
         ABN AMRO in accordance with the terms hereof, except as such
         enforceability may be limited by bankruptcy, insolvency,
         reorganization, receivership, moratorium and other similar Laws
         affecting the rights of creditors generally and general principles of
         equity, whether considered in a proceeding at law or in equity and
         except as rights to indemnification may be limited by federal or state
         securities laws or principles of public policy.

                 SECTION 7.  Conditions Precedent.  The effectiveness of this
Agreement shall be subject to the following conditions:

                 (a)      Atlas shall have received a certificate, dated the
         date hereof and signed by an executive officer of ABN AMRO,
         substantially in the form of Exhibit A hereto.

                 (b)      ABN AMRO shall have received (i) an opinion of Cahill
         Gordon & Reindel, counsel for Atlas, to the effect set forth in
         Exhibit B-1 hereto and (ii) an opinion of in-house legal counsel of
         Atlas, to the effect set forth in Exhibit B-2 hereto.

                 (c)      Atlas shall have received (i) an opinion of Vedder,
         Price, Kaufman & Kammholz, U.S. counsel for ABN AMRO, to the effect
         set forth in Exhibit C-1 hereto and (ii) an opinion of Clifford
         Chance, Netherlands counsel for Atlas, to the effect set forth in
         Exhibit C-2 hereto.

                 SECTION 8.  No Set-Off.  All amounts (including, without
limitation, those payments made in respect of Taxes (as defined and provided
for below)) payable by Atlas to ABN AMRO hereunder shall be paid in U.S.
Dollars and immediately available funds by
<PAGE>   16
                                       13

wire transfer to ABN AMRO Bank, New York, NY, ABA# 026009580, Account Name:
ABN AMRO Bank N.V., Chicago Branch, Account No. 610-001-1789-41, Reference:
Atlas 1998-1 or to such other account as ABN AMRO may direct from time to time
in writing to Atlas.  Except as set forth in the final sentence of Section
4(e)(i) hereof, to the extent permitted by applicable law, Atlas hereby waives
any and all rights of set-off, combination of accounts, right of retention or
similar right (whether arising under applicable law, contract or otherwise) it
may have against ABN AMRO with respect to the Secured Obligations and the
Breakage Obligations howsoever arising.  All amounts payable hereunder shall be
made free and clear of and without reduction for or on account of any and all
taxes, levies or other impositions or charges ("Taxes"), other than taxes based
on or measured by ABN AMRO'S net income, franchise taxes, or taxes required to
be withheld as a result of ABN AMRO failing to provide Atlas with a properly
executed IRS Form 4224 or successor form thereto (any such non-excluded taxes,
collectively, "Indemnified Taxes").  If Atlas shall be required by law to
deduct or withhold any Indemnified Taxes from or in respect of any sum payable
hereunder, then Atlas shall (i) pay such additional amounts to ABN AMRO, as may
be necessary in order that the actual amount received by the ABN AMRO, after
such required deduction or withholding equals the sum it would have received
had no such deductions or withholding been required to be made, (ii) make such
deductions or withholding, and (iii) pay the full amount deducted or withheld
(including in respect of such additional amounts) to the competent taxation
authority.  If the date on which any payment is due would otherwise fall on a
day which is not a Business Day, such payment shall be made on the next
succeeding Business Day, and no additional interest shall accrue in respect of
such extension.

                 SECTION 9.  Increased Costs.  In the event that any change in
law or governmental rule, regulation or order, or in the interpretation,
administration or application thereof (including the adoption of any new law or
governmental rule, regulation or order), or any determination of a court or by
any central bank or Government Entity, in each case that becomes effective
after the date hereof, or compliance by ABN AMRO (at its applicable lending
office) with any guideline, request or directive issued or made after the date
hereof by any such central bank or Government Entity (whether or not having the
force of law):

                 (i)      subjects ABN AMRO (or its applicable lending office)
         to any additional Indemnified Tax with respect to its obligations,
         commitments or extensions of credit hereunder or under any Deposit
         Agreement or any payments to ABN AMRO (or its applicable lending
         office) of any Indemnity Payment, interest, fees or any other amount
         payable under or in respect of this Agreement or any Deposit
         Agreement; or

                 (ii)     imposes, modifies or holds applicable any reserve
         (including any marginal, emergency, supplemental, special or other
         reserve), special deposit, compulsory loan, FDIC insurance or similar
         requirement against assets held by, or deposits in or for the account
         of, or advances or loans by, or other credit extended by, ABN AMRO;
<PAGE>   17
                                       14


and the result of any of the foregoing is that ABN AMRO shall incur increased
costs which are attributable to this Agreement or any Deposit Agreements or to
reduce any amount received or receivable by ABN AMRO (or its applicable lending
office) with respect to this Agreement; then, in any such case, Atlas shall pay
to ABN AMRO, within 15 days after receipt of the statement referred to in the
next sentence, such additional amount or amounts as may be necessary to
compensate ABN AMRO for any such increased cost or reduction in amounts
received or receivable hereunder; provided that Atlas shall not be liable in
respect of any such increased cost during such period ABN AMRO became aware and
failed to notify Atlas promptly in accordance with the next sentence if and to
the extent that prompt notice would have avoided or lessened payment by Atlas
hereunder relating to such period.  ABN AMRO, promptly after the occurrence of
such event, shall deliver to Atlas a written statement, setting forth in
reasonable detail the basis for calculating the additional amounts owed to ABN
AMRO under this Section 9, which statement, absent manifest error, shall be
prima facie evidence of such additional amounts.

                 SECTION 10.  Capital Adequacy.  If the adoption after the date
hereof of any applicable law, rule or regulation (or any provision thereof)
regarding capital adequacy, or any change after the date hereof in any existing
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or the promulgation after the date hereof of any guidelines, request
or directive regarding capital adequacy (whether or not having the force of
law) of any such governmental authority, central bank or comparable agency, has
or would have the effect of reducing the rate of return on the capital of ABN
AMRO or any corporation controlling ABN AMRO as a consequence of ABN AMRO's
commitments, obligations or extensions of credit hereunder or under any Deposit
Agreement to a level below that which ABN AMRO or such controlling corporation
could have achieved but for such adoption, change or promulgation (taking into
consideration the policies of ABN AMRO or such controlling corporation with
regard to capital adequacy), then from time to time, within five Business Days
after receipt by Atlas from ABN AMRO of the statement referred to in the next
sentence, Atlas shall pay to ABN AMRO such additional amount or amounts as will
compensate ABN AMRO or such controlling corporation on an after-tax basis for
such reduction. ABN AMRO shall deliver to Atlas a written statement, setting
forth in reasonable detail the basis of the calculation of such additional
amounts, which statement, absent manifest error, shall be prima facie evidence
of such additional amounts.

                 SECTION 11.  Fees.  In consideration of the Depositary
entering into this Agreement and the Deposit Agreements, Atlas agrees to pay
ABN AMRO a nonrefundable advisory fee equal to $125,000 on the date hereof.

                 SECTION 12.  Expenses; Indemnity.  (a)  Atlas shall pay all
reasonable out-of-pocket expenses incurred by ABN AMRO, including the
reasonable fees, charges and
<PAGE>   18
                                       15

disbursements of counsel for ABN AMRO, in connection with the preparation of
this Agreement or any amendments, modifications or waivers of the provisions
hereof.

                 (b)      The provisions of Section 9.1 of the Leased Aircraft
Participation Agreement attached as Exhibit A-1 to the Note Purchase Agreement,
together with related definitions and ancillary provisions, are hereby
incorporated herein by reference, as if set forth herein in full, mutatis
mutandis; provided that as incorporated herein, (i) each reference therein to

addition, we have assumed and have not verified (i) the accuracy as to factual
matters of each document we have reviewed and of the representations and
warranties set forth therein, including without limitation the accuracy of the
representations and warranties set forth in Section 5(a) of each of the Deposit
Agreements and Section 5(i) of each of the Escrow Agreements, and (ii) that (x)
the Indemnity Agreement and the Deposit Agreements have been duly authorized,
executed and delivered by you and (y) you have satisfied those legal
requirements that are applicable to you to the extent necessary to make the
Indemnity Agreement and the Deposit Agreements enforceable against you and that
each of the Indemnity Agreement and the Deposit Agreements is a valid, binding
and enforceable obligation of ABN AMRO Bank N.V., Chicago Branch.

                 Based on and subject to the foregoing, and to the other
assumptions, qualifications and limitations set forth herein, it is our opinion
that:

                 1.       Atlas is validly existing as a corporation in good
         standing under the laws of the State of Delaware.

                 2.       Atlas has the corporate power to enter the Indemnity
         Agreement and to perform its obligations thereunder.

                 3.       The execution and delivery by Atlas of the Indemnity
         Agreement have been duly authorized by all necessary corporate action
         of Atlas, and the Indemnity Agreement has been duly executed and
         delivered by Atlas.  The Indemnity Agreement is a valid and binding
         obligation of Atlas enforceable against Atlas in accordance with its
         terms.

                 4.       Atlas is not an "investment company" and is not a
         company "controlled" by an "investment company", in each case within
         the meaning of the Investment Company Act of 1940, as amended.

                 5.       The valid authorization, execution and delivery of
         the Indemnity Agreement by Atlas and the performance by Atlas of its
         respective obligations under
<PAGE>   32
                                      B-3

         the Indemnity Agreement do not require Atlas to obtain or effect any
         consent, approval, authorization, registration or qualification of or
         with any governmental agency or body of the United States or of the
         State of New York.  Neither the execution and delivery by Atlas of the
         Indemnity Agreement nor the consummation by Atlas of the transactions
         contemplated thereby to be consummated on the date hereof violates (i)
         Atlas' Certificate of Incorporation or By-Laws or (ii) any law or
         governmental rule or regulation known to us to be applicable to, or
         binding on, Atlas.

                 The foregoing opinions are subject to the following
assumptions, qualifications and limitations:

                 (a)      The opinions in paragraph 3 above are subject to (i)
         bankruptcy, insolvency, fraudulent transfer, fraudulent conveyance or
         other similar laws affecting the rights or remedies of creditors
         generally and (ii) general principles of equity (including without
         limitation doctrines of reasonableness and good faith and the possible
         unavailability of specific performance or injunctive relief and the
         general discretion of the court considering the matter), regardless of
         whether enforceability is considered in a proceeding in equity or at
         law.

                 (b)      We express no opinion as the enforceability of any
         provision contained in the Indemnity Agreement (i) that purports to
         establish or may be construed to establish evidentiary standards or
         (ii) as such provision relates to the jurisdiction of federal courts.

                 (c)      Provisions of the Indemnity Agreement which permit
         any Person to take action or make determinations, or to benefit from
         indemnities, contribution agreements or similar undertakings, or
         waivers, exculpatory provisions or similar provisions, may be subject
         to limitations imposed by law or by public policy considerations.

                 (d)      Insofar as the foregoing opinions relate to the valid
         existence and good standing of Atlas, they are based solely on a
         certificate of good standing received from the Secretary of State of
         the State of Delaware.

                 (e)      The foregoing opinions are limited to the law of the
         State of New York, the federal law of the United States of America and
         the General Corporation Law of the State of Delaware, in each case as
         in effect on the date hereof, except that we express no opinion with
         respect to (i) the laws, regulations or ordinances of any county, town
         or municipality or governmental subdivision or agency thereof, (ii)
         state securities or blue sky laws or, except as set forth in paragraph
         4 above, federal securities laws, including without limitation the
         Securities Act of 1933, as amended, and the Investment Company Act of
         1940, as amended, (iii) any federal or state tax,
<PAGE>   33
                                      B-4

         antitrust or fraudulent transfer or conveyance laws, (iv) the Employee
         Retirement Income Security Act of 1974, as amended, or (v) federal
         aviation laws and other federal laws relating to the operation and
         maintenance of the Aircraft by Atlas.  In addition, our opinions are
         based upon a review of those laws, statutes, rules and regulations
         which, in our experience, are normally applicable to transactions of
         the type contemplated by the Indemnity Agreement.

                 We are furnishing this opinion letter to you solely for your
benefit.  This opinion letter is not to be used, circulated, quoted or
otherwise referred to for any other purpose whatsoever without in each instance
our prior written consent.  This opinion letter speaks only as of the date
hereof and we disclaim any obligation to advise you of changes of law or fact
that occur after the date hereof.

                               [ATLAS LETTERHEAD]

                                                 February 9, 1998


ABN AMRO Branch N.V.,
Chicago Branch

Ladies and Gentlemen:

                 I am the [please supply precise title] of Atlas Air, Inc., a
Delaware corporation ("Atlas").  In such capacity, I and persons on my legal
staff have acted as counsel to Atlas in connection with the transactions
contemplated by the Indemnity Agreement dated as of February 9, 1998 between
you and Atlas (the "Indemnity Agreement").  Capitalized terms used but not
defined herein shall have the meanings ascribed to them in the Indemnity
Agreement or, if not defined therein, the Deposit Agreement (as defined in the
Indemnity Agreement).

                 In arriving at the opinions expressed below, I or members of
my legal staff have reviewed the following documents, each of which is dated as
of the date hereof, except where otherwise indicated above or below:

                 (a)      an executed copy of the Indemnity Agreement,

                 (b)      an executed copy of each of the three Deposit
         Agreements,

                 (c)      an executed copy of the Note Purchase Agreement,

                 (d)      an executed copy of each of the three Pass Through
         Trust Agreements,

                 (e)      an executed copy of each of the three Escrow
         Agreements, and

                 (f)      the documents delivered today by Atlas at the closing
         pursuant to the Placement Agreement dated January 27, 1998 among
         Morgan Stanley & Co. Incorporated, BT Alex. Brown Incorporated,
         Donaldson, Lufkin & Jenrette Securities Corporation and Goldman, Sachs
         & Co., including copies of Atlas' Restated Certificate of
         Incorporation (the "Certificate of Incorporation") and By-Laws
         certified by the Secretary of State of the State of Delaware and the
         Assistant Secretary of Atlas, respectively.
<PAGE>   35
                                      B2-2

                 In addition, I or members of my legal staff have reviewed the
originals or copies certified or otherwise identified to my or their
satisfaction of all such corporate records of Atlas and its Subsidiaries (as
defined below) and such other instruments and other certificates of public
officials, officers and representatives of Atlas and such other persons, and I
or members of my legal staff have made such investigations of law, as I deemed
appropriate as a basis for the opinions expressed below.

                 In arriving at the opinions expressed below, I and members of
my legal staff have assumed the authenticity of all documents submitted to us
as originals and the conformity to the originals of all documents submitted to
us as copies.  In addition, I and members of my legal staff have assumed and
have not verified the accuracy as to factual matters of each document I or they
have reviewed.  As used herein, the phrase "to my knowledge" shall mean to my
actual knowledge after reasonable investigation, but shall not be interpreted
to impute to me knowledge of others.

                 Based on the foregoing, and subject to the further
assumptions, qualifications and limitations set forth below, it is my opinion
that:


                 1.       Each of (i) Atlas and (ii) Atlas One, Inc., Atlas
         Freighter Leasing, Inc., Atlas Freighter Leasing II, Inc., Atlas Air
         Services Limited,  LHC Properties, Inc., Atlas Freightlease, Inc. and
         Genessee Insurance Company, Ltd. (together, the "Subsidiaries") has
         been duly incorporated and is an existing corporation in good standing
         under the laws of the jurisdiction of its incorporation, with
         corporate power to own, lease and operate its properties and conduct
         its business as described in the Offering Memorandum; each of Atlas
         and its Subsidiaries is duly qualified to do business as a foreign
         corporation in good standing in all other jurisdictions in which its
         ownership or lease of property or the conduct of its business requires
         such qualification, except where the failure to be so qualified would
         not have a material adverse effect on the business or consolidated
         financial condition of Atlas and the Subsidiaries taken as a whole.

                 2.       To my knowledge, except as disclosed in the Offering
         Memorandum, there is no action, suit or proceeding before or by any
         governmental agency or body or court, domestic or foreign, now pending
         against Atlas or any of the Subsidiaries or any of their respective
         properties that will have a material adverse effect on the ability of
         Atlas to perform its obligations under the Indemnity Agreement.

                 3.       Atlas is a "citizen of the United States" within the
         meaning of Section 40102(a)(15) of Title 49 of the United States Code,
         as amended, holding an air carrier operating certificate issued by the
         Secretary of Transportation pursuant to
<PAGE>   36
                                      B2-3

         Chapter 447 of Title 49 of the United States Code, as amended, for
         aircraft capable of carrying 10 or more individuals or 6,000 pounds or
         more of cargo.

                 4.       The execution, delivery and performance by Atlas of
         the Indemnity Agreement, and the consummation by Atlas of the
         transactions contemplated by the Indemnity Agreement, will not result
         in any violation of the provisions of the Certificate of Incorporation
         or By-Laws of Atlas or, to my knowledge, any applicable law,
         administrative regulation or any administrative or court decree, nor
         does any such action, to my knowledge, constitute a breach of, or
         default under, or (except as contemplated therein) result in the
         creation or imposition of any lien, charge or encumbrance upon any
         assets of Atlas or any of its subsidiaries pursuant to, any material
         contract, indenture, mortgage, loan agreement, note, lease or other
         instrument to which Atlas or any of its subsidiaries is a party or by
         which any of them are bound or to which any of the assets of Atlas or
         any of its subsidiaries is subject.

                 5.       The valid authorization, execution and delivery of
         the Indemnity Agreement by Atlas and the performance by Atlas of its
         obligations under the Indemnity Agreement do not require Atlas to
         obtain or effect any consent, approval, authorization, registration or
         qualification of or with any governmental agency or body of the United
         States or the State of Colorado (but I express no opinion as to any
         consent, approval, authorization, registration or qualification that
         may be required under federal aviation laws or other federal laws
         relating to the operation or maintenance of aircraft by Atlas).

                 The foregoing opinions are limited to the federal law of the
United States of America, the General Corporation Law of the State of Delaware
and the law of the State of Texas, in each case as in effect on the date
hereof, except that I express no opinion with respect to (i) the laws,
regulations or ordinances of any county, town or municipality or governmental
subdivision or agency thereof, (ii) federal or state securities or blue sky
laws, including without limitation the Securities Act and the Investment
Company Act of 1940, as amended, (iii) any federal or state tax, antitrust or
fraudulent transfer or conveyance laws or (iv) the Employee Retirement Income
Security Act of 1974, as amended.  In addition, my opinions are based upon a
review of those laws, statutes, rules and regulations which, in our experience,
are normally applicable to transactions of the type contemplated by the
Indemnity Agreement.

                 I am furnishing this opinion letter to you solely for your
benefit in connection with the transactions described above.  This opinion
letter is not to be used, circulated, quoted or otherwise referred to by any
other person or for any other purpose.  This opinion letter speaks only as of
the date hereof and I disclaim any obligation to advise you of changes of law
or fact that occur after the date hereof.

                                                                February 9, 1998
 


Atlas Air, Inc.


RE:      ATLAS AIR, INC. PASS THROUGH
         CERTIFICATES SERIES 1998-1

Ladies and Gentlemen:

                 We have acted as special counsel to ABN AMRO Bank N.V.,
Chicago Branch (the "Branch") in connection with the Indemnity Agreement dated
February 9, 1998 (the "Indemnity Agreement") between Atlas Air, Inc. and the
Branch.  Capitalized terms used but not defined herein shall have the meaning
ascribed to them in the Indemnity Agreement.

                 In rendering the opinions set forth herein, we have examined
the originals or copies, certified or otherwise identified to my satisfaction,
of such records, certificates and documents as we have deemed necessary or
relevant as basis for our opinion.  In such examination, we have assumed the
genuineness of all signatures, the authenticity of all documents submitted to
us as originals, and the conformity to originals of all documents we have
examined or upon certificates of the Branch or its officer or of public
officials or other persons.  We have assumed for purposes of the opinion
hereinafter set forth that the Indemnity Agreement has been duly authorized,
executed and delivered by all parties thereto other than the Branch.

                 We are members of the Bar of the State of Illinois and the
State of New York and do not purport to be experts on, or to express any
opinion herein concerning, any law other than the laws of the State of New York
and the federal law of the United States of America.  Without limiting the
generality of the foregoing, we express no opinion as to the effect of the laws
of any jurisdiction, other than the State of New York.

                 Based upon and subject to the foregoing, we are of the opinion
as follows:

                 1.       The Branch is duly qualified to conduct banking
         business in the State of Illinois through its Chicago Branch, with
         power and authority to enter into and perform its obligations under
         the Indemnity Agreement.
<PAGE>   38
                                      C-2

                 2.       The execution and delivery by the Branch of the
         Indemnity Agreement and the consummation of the transactions
         contemplated therein have been duly authorized by the Branch and will
         not violate, to the best of our knowledge, any law, governmental rule
         or regulation of the United States of America or the State of
         Illinois, its articles of association or by-laws, or any order, writ,
         injunction or decree of any court or governmental agency against it.

                 3.       To our knowledge, there are no pending or threatened
         actions, suits, investigations or proceedings (whether or not
         purportedly on behalf of the Branch against or affecting the Branch of
         any of its property before or by any court or administrative agency
         which, individually or in the aggregate, if adversely determined, (i)
         would adversely affect the Branch's ability to perform its obligations
         under the Indemnity Agreement or (ii) would call in to question or
         challenge the validity of the Indemnity Agreement or the
         enforceability thereof.

                 This opinion is rendered solely for your benefit in connection
with the transaction contemplated by the Indemnity Agreement and is not to be
circulated, quoted or otherwise referred to for any other purpose without our
prior written permission.  This opinion is referred only as of the date hereof,
and we disclaim any obligation to supplement this opinion letter for events
occurring or coming to our attention after the date hereof.

                  --------------------------------------------


Ladies and Gentlemen:

                 We have acted as Dutch legal counsel to ABN AMRO Bank N.V.
("ABN AMRO"), acting through its Chicago branch (the "Branch"), in connection
with the Indemnity Agreement dated February 9, 1998 (the "Indemnity Agreement")
between Atlas Air, Inc. ("Atlas") and ABN AMRO.  Capitalized terms used but not
defined herein shall have the meanings ascribed to them in the Indemnity
Agreement.

                 We have examined such documents and questions on law as we
have considered necessary and appropriate for purposes of this opinion.  No
opinion is expressed as to any matters governed by any laws other than the laws
of the Netherlands.

                 We have assumed for the purpose of our opinion hereinafter
expressed that the Indemnity Agreement to which ABN AMRO is a party will
constitute the legal, valid and binding obligation of ABN AMRO in accordance
with New York law and United States Federal Law.

                 Based upon the foregoing (but limited in all respects to the
laws of the Netherlands), we advise you that it is our opinion that:

                 1.       ABN AMRO is a banking corporation duly organized and
         validly existing in good standing under the laws of the Netherlands
         and has full corporate power to execute, deliver and perform its
         obligations under the Indemnity Agreement.

                 2.       No consent, approval, authorization, or order of, or
         filing with, any governmental agency or body or any court of the
         Netherlands is required for the valid authorization, execution and
         delivery by ABN AMRO of the Indemnity Agreement and for the
         consummation of the transactions contemplated therein except such as
         may have been obtained.
<PAGE>   40
                                      C2-2

                 3.       The execution and delivery by the Depositary of the
         Indemnity Agreement and the consummation of the transactions
         contemplated therein have been duly authorized by ABN AMRO and will
         not violate any law, governmental rule or regulation of the
         Netherlands or its articles of association or bylaws.

                 4.       The Indemnity Agreement has been duly authorized by
         ABN AMRO and, when duly executed and delivered by two authorized
         officers of the Branch, will constitute the legal, valid and binding
         obligations of ABN AMRO enforceable in accordance with its terms.

                 5.       We have no knowledge of any pending or threatened
         actions, suits investigations or proceedings (whether or not
         purportedly on behalf of ABN AMRO) in the Netherlands against or
         affecting ABN AMRO or any of its property before or by any court or
         administrative agency which, individually or in the aggregate, if
         adversely determined, (i) would adversely affect ABN AMRO's ability to
         perform its obligations under the Indemnity Agreement or (ii) would
         call into question or challenge the validity of the Indemnity
         Agreement or the enforceability thereof.

                 6.       Atlas will alternatively be able to proceed against
         ABN AMRO's Head Office in Amsterdam, the Netherlands, if the Branch
         defaults in its obligation to such party under the Indemnity
         Agreement.

                 This opinion is limited to the matters expressly set forth
above and no opinion is implied or may be inferred beyond the matters expressly
so stated.  This opinion is delivered to you in connection with the above-
referenced transaction and may not be utilized or quoted by you for any other
purpose whatsoever or delivered to any other person without our prior consent.


                                       Very truly yours

Credit Agreement and the Intercreditor Agreement are referred to herein as the
Liquidity Agreements. I have also represented MSDWD in connection with the
related Guarantee, dated as of January __, 1998 (the "Guarantee"), of MSDWD.

     I have examined such corporate records, certificates and other documents,
and such questions of law, as I have considered necessary or appropriate for
the purposes of this opinion. Upon the basis of such examination, it is my
opinion that:

     (1) Each of Morgan Stanley and MSDWD has been duly incorporated and is an
     existing corporation in good standing under the laws of the State of 
     Delaware.

     (2) Each of Morgan Stanley and MSDWD has the corporate power and authority
     to enter into and perform its obligations under the Liquidity Agreements 
     and the Guarantee, respectively.

     (3) Payments due under the Liquidity Agreements (assuming the Liquidity
     Agreements are valid and binding obligations of Morgan Stanley) and the
     Guarantee rank pari passu with the unsecured and unsubordinate obligations 
     of Morgan Stanley and MSDWD, respectively.

     (4) The Liquidity Agreements have been duly authorized, executed and
     delivered by Morgan Stanley, the Guarantee has been duly authorized,
     executed and delivered by MSDWD and the Guarantee constitutes a valid and
     legally binding obligation of MSDWD enforceable in accordance with its
     terms, subject to bankruptcy, insolvency, fraudulent transfer,
     reorganization, moratorium and similar

Placement Agents, for and on behalf of each of the Investors, hereby
irrevocably appoints, authorizes and directs the Escrow Agent to act as escrow

its affiliates' officers, directors, employees and agents): (a) shall have no
duties or responsibilities except those expressly set forth in this Agreement;
(b) shall not be responsible to the Pass Through Trustee or the Investors for
any recitals, statements, representations or warranties of any person other

entity (other than the Escrow Agent) to perform any of its obligations

                 Section 1.02.    Instruction; Etc.  The Placement Agents, for
and on behalf of each of the Investors, hereby irrevocably instruct the Escrow
Agent, and the Escrow Agent agrees, (a) to enter into the Deposit Agreement,
(b) to appoint the Paying Agent as provided in this Agreement, (c) upon receipt
at any time and from time to time prior to the Delivery Period Termination Date
(as defined in the Note Purchase Agreement) of a certificate substantially in
the form of Exhibit B hereto (a "Withdrawal Certificate") executed by the Pass
Through Trustee, together with an attached Notice of Purchase Withdrawal in
substantially the form of Exhibit A to the Deposit Agreement duly completed by
the Pass Through Trustee (the "Applicable Notice of Purchase Withdrawal" and
the withdrawal to which it relates, a "Purchase Withdrawal"), immediately to
execute the Applicable Notice of Purchase Withdrawal as Escrow Agent and
transmit it to the Depositary by facsimile transmission in accordance with the
Deposit Agreement; provided that, upon the request of the Pass Through Trustee
after such transmission, the Escrow Agent shall cancel such Applicable Notice
of Purchase Withdrawal, (d) upon receipt at any time and from time to time
prior to the Delivery Period Termination Date (as defined in the Note Purchase
Agreement) of a certificate substantially in the form of Exhibit C hereto (a
"Prepayment Withdrawal Certificate") executed by the Pass Through Trustee,
together with an attached Notice of Prepayment Withdrawal in substantially the
form of Exhibit B to the Deposit Agreement duly completed by the Pass Through
Trustee (the "Applicable Notice of Prepayment Withdrawal" and the withdrawal to
which it relates, a "Prepayment Withdrawal"), immediately to execute the
Applicable Notice of Prepayment Withdrawal as Escrow Agent and transmit it to
the Depositary by facsimile transmission in accordance with the Deposit
Agreement; provided that, upon the request of the Pass Through Trustee after
such transmission, the Escrow Agent shall cancel such Applicable Notice of
Prepayment Withdrawal, and (e) if there are any undrawn Deposits (as defined in
the Deposit Agreement) on the earlier of (i) the Delivery Period Termination
Date and (ii) the day on which the Escrow Agent receives notice from the Pass
Through Trustee that the Pass Through Trustee's obligation to purchase
Equipment Notes under the Note Purchase Agreement has terminated, to give
notice to the Depositary (with a copy to the Paying Agent) substantially in the
form of Exhibit C to the Deposit Agreement requesting a withdrawal of all of
the remaining Deposits, together with accrued and unpaid interest on such
Deposits to the date of withdrawal, on the 35th day after the date that such
notice of withdrawal is given to the Depositary (or, if not a Business Day, on
the next succeeding Business Day) (a "Final Withdrawal"), provided that if the
day scheduled for the Final Withdrawal in accordance with the foregoing is
within 10 days before or after a Regular Distribution Date, then the Escrow
Agent shall request that such requested Final Withdrawal be made on such
Regular Distribution Date (the date of such requested withdrawal, the "Final
Withdrawal Date").  If for any reason the Escrow Agent shall have failed to
give the Final Withdrawal Notice to the Depositary on or before June 29, 1999
(provided, that if a labor strike or work stoppage occurs at The Boeing Company
prior to such date, such date shall be extended by adding thereto the number of
days that each such labor strike or work stoppage continues in effect), and
there are unwithdrawn Deposits on such date, the Final Withdrawal Date shall be
deemed to be the Delivery Period Termination Date.

                 Section 1.03.    Initial Escrow Amount; Issuance of Escrow
Receipts.  The Escrow Agent hereby directs the Placement Agents to, and the
Placement Agents hereby acknowledge that on the date hereof they shall,
irrevocably deliver to the Depositary on behalf of the Escrow Agent, an amount
in U.S. dollars ("Dollars") and immediately available funds equal to
$300,254,000 for deposit on behalf of the Escrow Agent with the Depositary in
accordance with Section 2.1 of the Deposit Agreement.  The Placement Agents
hereby instruct the Escrow Agent, upon receipt of such sum from the Placement
Agents, to confirm such receipt by executing and delivering to the Pass Through
Trustee an Escrow Receipt in the form of Exhibit A hereto (an "Escrow
Receipt"), (a) to be affixed by the Pass Through Trustee to each Certificate
and (b) to evidence the same percentage interest (the "Escrow Interest") in the
Account Amounts (as defined below) as the Fractional Undivided Interest in the
Pass Through Trust evidenced by the Certificate to which it is to be affixed.
The Escrow Agent shall provide to the Pass Through Trustee for attachment to
each Certificate newly issued under and in accordance with the Pass Through
Trust Agreement an executed Escrow Receipt as the Pass Through Trustee may from
time to time request of the Escrow Agent.  Each Escrow Receipt shall be
registered by the Escrow Agent in a register (the "Register") maintained by the
Escrow Agent in the same name and same manner as the Certificate to which it is
attached and may not thereafter be detached from such Certificate to which it
is to be affixed prior to the distribution of the Final Withdrawal (the "Final
Distribution").  After the Final Distribution, no additional Escrow Receipts
shall be issued and the Pass Through Trustee shall request the return to the
Escrow Agent for cancellation of all outstanding Escrow Receipts.

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

                 Section 1.05.    Mutilated, Destroyed, Lost or Stolen Escrow
Receipt.  If (a) any mutilated Escrow Receipt is surrendered to the Escrow
Agent or the Escrow Agent receives evidence to its satisfaction of the
destruction, loss or theft of any Escrow Receipt and (b) there is delivered to
the Escrow Agent and the Pass Through Trustee such security, indemnity or bond,
as may be required by them to hold each of them harmless, then, absent notice
to the Escrow Agent or the Pass Through Trustee that such destroyed, lost or
stolen Escrow Receipt has been acquired by a bona fide purchaser, and provided
that the





                                       4
<PAGE>   8
requirements of Section 8-405 of the Uniform Commercial Code in effect in any
applicable jurisdiction are met, the Escrow Agent shall execute, authenticate
and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost
or stolen Escrow Receipt, a new Escrow Receipt or Escrow Receipts and of like
Escrow Interest in the Account Amounts and bearing a number not
contemporaneously outstanding.

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

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

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

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

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

Standard & Poor's Rating Group, a division of McGraw-Hill Inc., and Fitch IBCA,
Inc. that the replacement of the Escrow Agent with the successor Escrow Agent
will not result in (a) a reduction of the rating for the Certificates below the
then current rating for the Certificates or (b) a withdrawal or suspension of
the rating of the Certificates.

                 Section 1.08.    Persons Deemed Owners.  Prior to due
presentment of a Certificate for registration of transfer, the Escrow Agent and
the Paying Agent may treat the Person in whose name any Escrow Receipt is
registered (as of the day of determination) as the owner of such Escrow Receipt
for the purpose of receiving distributions pursuant to this Agreement and for
all other purposes whatsoever, and neither the Escrow Agent nor the Paying
Agent shall be affected by any notice to the contrary.

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

                 SECTION 2.       Paying Agent.

                 Section 2.01.    Appointment of Paying Agent.  The Escrow
Agent hereby irrevocably appoints and authorizes the Paying Agent to act as its
paying agent hereunder, for the benefit of the Investors, for such specific
purposes and with such powers as are specifically delegated to the Paying Agent
by the terms of this Agreement, together with such other powers as are
reasonably incidental thereto.  Any and all money received and held by the
Paying Agent under this Agreement or the Deposit Agreement shall be held in the
Paying Agent Account for the benefit of the Investors.   The Paying Agent
(which term as used in this sentence shall include reference to its affiliates
and its own and its affiliates' officers, directors, employees and agents):
(a) shall have no duties or responsibilities except those expressly set forth
in this Agreement, and shall not by reason of this Agreement be a trustee for
the Escrow Agent; (b) shall not be responsible to the Escrow Agent for any
recitals, statements, representations or warranties of any person other then
itself contained in this Agreement or for the failure by the Escrow Agent or
any other person or entity (other than the Paying Agent) to perform any of its
obligations hereunder (whether or not the Paying Agent shall have any knowledge
thereof); and (c) shall not be responsible for any action taken or omitted to
be taken by it hereunder or provided for herein or in connection herewith,
except for its own willful misconduct or gross negligence (or simple negligence
in connection with the handling of funds).

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

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

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

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

                 (c)      If any payment of interest or principal in respect of
         the Final Withdrawal is not received by the Paying Agent within five
         days of the applicable date when due, then it shall be distributed to
         Receiptholders after actual receipt by the Paying Agent on the same
         basis as a Special Payment is distributed under the Pass Through Trust
         Agreement.

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

                 Section 2.04.    Withholding Taxes.  The Paying Agent shall
exclude and withhold from each distribution of accrued interest on the Deposits
(as defined in the Deposit Agreement) and any amount in respect of the Final
Withdrawal any and all withholding taxes





                                       7
<PAGE>   11
applicable thereto as required by law.  The Paying Agent agrees to act as such
withholding agent and, in connection therewith, whenever any present or future
taxes or similar charges are required to be withheld with respect to any
amounts payable in respect of the Deposits (as defined in the Deposit
Agreement) or the escrow amounts, to withhold such amounts and timely pay the
same to the appropriate authority in the name of and on behalf of the
Receiptholders, that it will file any necessary withholding tax returns or
statements when due, and that, as promptly as possible after the payment
thereof, it will deliver to each such Receiptholder appropriate documentation
showing the payment thereof, together with such additional documentary evidence
as such Receiptholder may reasonably request from time to time.  The Paying
Agent agrees to file any other information reports as it may be required to
file under United States law.

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

                 Section 2.06.    Notice of Final Withdrawal.  Promptly after
receipt by the Paying Agent of notice that the Escrow Agent has requested a
Final Withdrawal or that a Final Withdrawal will be made, the Paying Agent
shall cause notice of the distribution of the Final Withdrawal to be mailed to
each of the Receiptholders at its address as it appears in the Register.  Such
notice shall be mailed not less than 15 days prior to the Final Withdrawal
Date.  Such notice shall set forth:

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

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





                                       8
<PAGE>   12
                 (iii)    if the Final Withdrawal Date is the same date as a
         Regular Distribution Date, the total amount to be received on such
         date for each $1,000 face amount Certificate (based on information
         provided by the Pass Through Trustee).

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

                 SECTION 3.       Payments.  If, notwithstanding the
instructions in Section 4 of the Deposit Agreement that all amounts payable to
the Escrow Agent under the Deposit Agreement be paid by the Depositary directly
to the Paying Agent or the Pass Through Trustee (depending on the
circumstances), the Escrow Agent receives any payment thereunder, then the
Escrow Agent shall forthwith pay such amount in Dollars and in immediately
available funds by wire transfer to (a) in the case of a payment of accrued
interest on the Deposits (as defined in the Deposit Agreement) or any Final
Withdrawal, directly to the Paying Agent Account and (b) in the case of any
Purchase Withdrawal, directly to the Pass Through Trustee or its designee as
specified and in the manner provided in the Applicable Notice of Purchase
Withdrawal.  The Escrow Agent hereby waives any and all rights of set-off,
combination of accounts, right of retention or similar right (whether arising
under applicable law, contract or otherwise) it may have against amounts
payable to the Paying Agent howsoever arising.

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

                 SECTION 5.       Representations and Warranties of the Escrow

                                     No. __

                 This Escrow Receipt evidences a fractional undivided interest
in amounts ("Account Amounts") from time to time deposited into a certain
paying agent account (the "Paying Agent Account") described in the Escrow and
Paying Agent Agreement (Class A) dated as of February 9, 1998 (as amended,
modified or supplemented from time to time, the "Escrow and Paying Agent
Agreement") among First Security Bank, National Association, as Escrow Agent
(in such capacity, together with its successors in such capacity, the "Escrow
Agent"), Morgan Stanley & Co. Incorporated, BT Alex. Brown Incorporated,
Donaldson, Lufkin Jenrette Securities Corporation and Goldman, Sachs & Co., as
Placement Agents, Wilmington Trust Company as Pass Through Trustee (in such
capacity, together with its successors in such capacity, the "Pass Through
Trustee") and Wilmington Trust Company, as paying agent (in such capacity,
together with its successors in such capacity, the "Paying Agent").
Capitalized terms not defined herein shall have the meanings assigned to them
in the Escrow and Paying Agent Agreement.

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

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

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

Through Trustee, the Paying Agent or the Escrow Agent, except as expressly
provided herein or in the Pass Through Trust Agreement.  No Receiptholder of
this Escrow Receipt shall have any right to vote or in any manner otherwise
control the operation and management of the Paying Agent Account, nor shall
anything set forth herein, or contained in the terms of this Escrow Receipt, be
construed so as to constitute the Receiptholders from time to time as partners
or members of an association.

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

                 The Paying Agent may treat the person in whose name the
Certificate to which this Escrow Receipt is attached as the owner hereof for
all purposes, and the Paying Agent shall not be affected by any notice to the
contrary.

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

                 IN WITNESS WHEREOF, the Escrow Agent has caused this Escrow
Receipt to be duly executed.

                 SECTION 1.       Escrow Agent.

                 Section 1.01.    Appointment of Escrow Agent.  Each of the
Placement Agents, for and on behalf of each of the Investors, hereby
irrevocably appoints, authorizes and directs the Escrow Agent to act as escrow
agent and fiduciary hereunder and under the Deposit Agreement for such specific
purposes and with such powers as are specifically delegated to the Escrow Agent

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

                 Section 1.02.    Instruction; Etc.  The Placement Agents, for
and on behalf of each of the Investors, hereby irrevocably instruct the Escrow
Agent, and the Escrow Agent agrees, (a) to enter into the Deposit Agreement,
(b) to appoint the Paying Agent as provided in this Agreement, (c) upon receipt
at any time and from time to time prior to the Delivery Period Termination Date
(as defined in the Note Purchase Agreement) of a certificate substantially in
the form of Exhibit B hereto (a "Withdrawal Certificate") executed by the Pass
Through Trustee, together with an attached Notice of Purchase Withdrawal in
substantially the form of Exhibit A to the Deposit Agreement duly completed by
the Pass Through Trustee (the "Applicable Notice of Purchase Withdrawal" and
the withdrawal to which it relates, a "Purchase Withdrawal"), immediately to
execute the Applicable Notice of Purchase Withdrawal as Escrow Agent and
transmit it to the Depositary by facsimile transmission in accordance with the
Deposit Agreement; provided that, upon the request of the Pass Through Trustee
after such transmission, the Escrow Agent shall cancel such Applicable Notice
of Purchase Withdrawal, (d) upon receipt at any time and from time to time
prior to the Delivery Period Termination Date (as defined in the Note Purchase
Agreement) of a certificate substantially in the form of Exhibit C hereto (a
"Prepayment Withdrawal Certificate") executed by the Pass Through Trustee,
together with an attached Notice of Prepayment Withdrawal in substantially the
form of Exhibit B to the Deposit Agreement duly completed by the Pass Through
Trustee (the "Applicable Notice of Prepayment Withdrawal" and the withdrawal to
which it relates, a "Prepayment Withdrawal"), immediately to execute the
Applicable Notice of Prepayment Withdrawal as Escrow Agent and transmit it to
the Depositary by facsimile transmission in accordance with the Deposit
Agreement; provided that, upon the request of the Pass Through Trustee after
such transmission, the Escrow Agent shall cancel such Applicable Notice of
Prepayment Withdrawal, and (e) if there are any undrawn Deposits (as defined in
the Deposit Agreement) on the earlier of (i) the Delivery Period Termination
Date and (ii) the day on which the Escrow Agent receives notice from the Pass
Through Trustee that the Pass Through Trustee's obligation to purchase
Equipment Notes under the Note Purchase Agreement has terminated, to give
notice to the Depositary (with a copy to the Paying Agent) substantially in the
form of Exhibit C to the Deposit Agreement requesting a withdrawal of all of
the remaining Deposits, together with accrued and unpaid interest on such
Deposits to the date of withdrawal, on the 35th day after the date that such
notice of withdrawal is given to the Depositary (or, if not a Business Day, on
the next succeeding Business Day) (a "Final Withdrawal"), provided that if the
day scheduled for the Final Withdrawal in accordance with the foregoing is
within 10 days before or after a Regular Distribution Date, then the Escrow
Agent shall request that such requested Final Withdrawal be made on such
Regular Distribution Date (the date of such requested withdrawal, the "Final
Withdrawal Date").  If for any reason the Escrow Agent shall have failed to
give the Final Withdrawal Notice to the Depositary on or before June 29, 1999
(provided, that if a labor strike or work stoppage occurs at The Boeing Company
prior to such date, such date shall be extended by adding thereto the number of
days that each such labor strike or work stoppage continues in effect), and
there are unwithdrawn Deposits on such date, the Final Withdrawal Date shall be
deemed to be the Delivery Period Termination Date.

                 Section 1.03.    Initial Escrow Amount; Issuance of Escrow
Receipts.  The Escrow Agent hereby directs the Placement Agents to, and the
Placement Agents hereby acknowledge that on the date hereof they shall,
irrevocably deliver to the Depositary on behalf of the Escrow Agent, an amount
in U.S. dollars ("Dollars") and immediately available funds equal to
$115,481,000 for deposit on behalf of the Escrow Agent with the Depositary in
accordance with Section 2.1 of the Deposit Agreement.  The Placement Agents
hereby instruct the Escrow Agent, upon receipt of such sum from the Placement
Agents, to confirm such receipt by executing and delivering to the Pass Through
Trustee an Escrow Receipt in the form of Exhibit A hereto (an "Escrow
Receipt"), (a) to be affixed by the Pass Through Trustee to each Certificate
and (b) to evidence the same percentage interest (the "Escrow Interest") in the
Account Amounts (as defined below) as the Fractional Undivided Interest in the
Pass Through Trust evidenced by the Certificate to which it is to be affixed.
The Escrow Agent shall provide to the Pass Through Trustee for attachment to
each Certificate newly issued under and in accordance with the Pass Through
Trust Agreement an executed Escrow Receipt as the Pass Through Trustee may from
time to time request of the Escrow Agent.  Each Escrow Receipt shall be
registered by the Escrow Agent in a register (the "Register") maintained by the
Escrow Agent in the same name and same manner as the Certificate to which it is
attached and may not thereafter be detached from such Certificate to which it
is to be affixed prior to the distribution of the Final Withdrawal (the "Final
Distribution").  After the Final Distribution, no additional Escrow Receipts
shall be issued and the Pass Through Trustee shall request the return to the
Escrow Agent for cancellation of all outstanding Escrow Receipts.

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

                 Section 1.05.    Mutilated, Destroyed, Lost or Stolen Escrow
Receipt.  If (a) any mutilated Escrow Receipt is surrendered to the Escrow
Agent or the Escrow Agent receives evidence to its satisfaction of the
destruction, loss or theft of any Escrow Receipt and (b) there is delivered to
the Escrow Agent and the Pass Through Trustee such security, indemnity or bond,
as may be required by them to hold each of them harmless, then, absent notice
to the Escrow Agent or the Pass Through Trustee that such destroyed, lost or
stolen Escrow Receipt has been acquired by a bona fide purchaser, and provided
that the





                                       4
<PAGE>   8
requirements of Section 8-405 of the Uniform Commercial Code in effect in any
applicable jurisdiction are met, the Escrow Agent shall execute, authenticate
and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost
or stolen Escrow Receipt, a new Escrow Receipt or Escrow Receipts and of like
Escrow Interest in the Account Amounts and bearing a number not
contemporaneously outstanding.

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

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

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

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

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





                                       5

Standard & Poor's Rating Group, a division of McGraw-Hill Inc., and Fitch IBCA,
Inc. that the replacement of the Escrow Agent with the successor Escrow Agent
will not result in (a) a reduction of the rating for the Certificates below the
then current rating for the Certificates or (b) a withdrawal or suspension of
the rating of the Certificates.

                 Section 1.08.    Persons Deemed Owners.  Prior to due
presentment of a Certificate for registration of transfer, the Escrow Agent and
the Paying Agent may treat the Person in whose name any Escrow Receipt is
registered (as of the day of determination) as the owner of such Escrow Receipt
for the purpose of receiving distributions pursuant to this Agreement and for
all other purposes whatsoever, and neither the Escrow Agent nor the Paying
Agent shall be affected by any notice to the contrary.

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

                 SECTION 2.       Paying Agent.

                 Section 2.01.    Appointment of Paying Agent.  The Escrow
Agent hereby irrevocably appoints and authorizes the Paying Agent to act as its
paying agent hereunder, for the benefit of the Investors, for such specific
purposes and with such powers as are specifically delegated to the Paying Agent
by the terms of this Agreement, together with such other powers as are
reasonably incidental thereto.  Any and all money received and held by the
Paying Agent under this Agreement or the Deposit Agreement shall be held in the
Paying Agent Account for the benefit of the Investors.   The Paying Agent
(which term as used in this sentence shall include reference to its affiliates
and its own and its affiliates' officers, directors, employees and agents):
(a) shall have no duties or responsibilities except those expressly set forth
in this Agreement, and shall not by reason of this Agreement be a trustee for
the Escrow Agent; (b) shall not be responsible to the Escrow Agent for any
recitals, statements, representations or warranties of any person other then
itself contained in this Agreement or for the failure by the Escrow Agent or
any other person or entity (other than the Paying Agent) to perform any of its
obligations hereunder (whether or not the Paying Agent shall have any knowledge
thereof); and (c) shall not be responsible for any action taken or omitted to
be taken by it hereunder or provided for herein or in connection herewith,
except for its own willful misconduct or gross negligence (or simple negligence
in connection with the handling of funds).

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

<PAGE>   10
                 Section 2.03.    Payments from Paying Agent Account.  The
Escrow Agent hereby irrevocably instructs the Paying Agent, and the Paying
Agent agrees to act, as follows:

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

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

                 (c)      If any payment of interest or principal in respect of
         the Final Withdrawal is not received by the Paying Agent within five
         days of the applicable date when due, then it shall be distributed to
         Receiptholders after actual receipt by the Paying Agent on the same
         basis as a Special Payment is distributed under the Pass Through Trust
         Agreement.

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

                 Section 2.04.    Withholding Taxes.  The Paying Agent shall
exclude and withhold from each distribution of accrued interest on the Deposits
(as defined in the Deposit Agreement) and any amount in respect of the Final
Withdrawal any and all withholding taxes





                                       7
<PAGE>   11
applicable thereto as required by law.  The Paying Agent agrees to act as such
withholding agent and, in connection therewith, whenever any present or future
taxes or similar charges are required to be withheld with respect to any
amounts payable in respect of the Deposits (as defined in the Deposit
Agreement) or the escrow amounts, to withhold such amounts and timely pay the
same to the appropriate authority in the name of and on behalf of the
Receiptholders, that it will file any necessary withholding tax returns or
statements when due, and that, as promptly as possible after the payment
thereof, it will deliver to each such Receiptholder appropriate documentation
showing the payment thereof, together with such additional documentary evidence
as such Receiptholder may reasonably request from time to time.  The Paying
Agent agrees to file any other information reports as it may be required to
file under United States law.

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

                 Section 2.06.    Notice of Final Withdrawal.  Promptly after
receipt by the Paying Agent of notice that the Escrow Agent has requested a
Final Withdrawal or that a Final Withdrawal will be made, the Paying Agent
shall cause notice of the distribution of the Final Withdrawal to be mailed to
each of the Receiptholders at its address as it appears in the Register.  Such
notice shall be mailed not less than 15 days prior to the Final Withdrawal
Date.  Such notice shall set forth:

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

                 (ii)     the amount of the payment in respect of the Final

instructions in Section 4 of the Deposit Agreement that all amounts payable to
the Escrow Agent under the Deposit Agreement be paid by the Depositary directly

                                     No. __

                 This Escrow Receipt evidences a fractional undivided interest
in amounts ("Account Amounts") from time to time deposited into a certain
paying agent account (the "Paying Agent Account") described in the Escrow and
Paying Agent Agreement (Class B) dated as of February 9, 1998 (as amended,
modified or supplemented from time to time, the "Escrow and Paying Agent
Agreement") among First Security Bank, National Association, as Escrow Agent
(in such capacity, together with its successors in such capacity, the "Escrow
Agent"), Morgan Stanley & Co. Incorporated, BT Alex. Brown Incorporated,
Donaldson, Lufkin Jenrette Securities Corporation and Goldman, Sachs & Co., as
Placement Agents, Wilmington Trust Company as Pass Through Trustee (in such
capacity, together with its successors in such capacity, the "Pass Through
Trustee") and Wilmington Trust Company, as paying agent (in such capacity,
together with its successors in such capacity, the "Paying Agent").
Capitalized terms not defined herein shall have the meanings assigned to them
in the Escrow and Paying Agent Agreement.

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

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

provided herein or in the Pass Through Trust Agreement.  No Receiptholder of
this Escrow Receipt shall have any right to vote or in any manner otherwise

and on behalf of each of the Investors, hereby irrevocably instruct the Escrow
Agent, and the Escrow Agent agrees, (a) to enter into the Deposit Agreement,

Prepayment Withdrawal, and (e) if there are any undrawn Deposits (as defined in
the Deposit Agreement) on the earlier of (i) the Delivery Period Termination
Date and (ii) the day on which the Escrow Agent receives notice from the Pass

Equipment Notes under the Note Purchase Agreement has terminated, to give
notice to the Depositary (with a copy to the Paying Agent) substantially in the
form of Exhibit C to the Deposit Agreement requesting a withdrawal of all of
the remaining Deposits, together with accrued and unpaid interest on such
Deposits to the date of withdrawal, on the 35th day after the date that such
notice of withdrawal is given to the Depositary (or, if not a Business Day, on
the next succeeding Business Day) (a "Final Withdrawal"), provided that if the
day scheduled for the Final Withdrawal in accordance with the foregoing is
within 10 days before or after a Regular Distribution Date, then the Escrow
Agent shall request that such requested Final Withdrawal be made on such
Regular Distribution Date (the date of such requested withdrawal, the "Final
Withdrawal Date").  If for any reason the Escrow Agent shall have failed to
give the Final Withdrawal Notice to the Depositary on or before June 29, 1999
(provided, that if a labor strike or work stoppage occurs at The Boeing Company
prior to such date, such date shall be extended by adding thereto the number of
days that each such labor strike or work stoppage continues in effect), and
there are unwithdrawn Deposits on such date, the Final Withdrawal Date shall be
deemed to be the Delivery Period Termination Date.

irrevocably deliver to the Depositary on behalf of the Escrow Agent, an amount
in U.S. dollars ("Dollars") and immediately available funds equal to
$123,180,000 for deposit on behalf of the Escrow Agent with the Depositary in
accordance with Section 2.1 of the Deposit Agreement.  The Placement Agents
hereby instruct the Escrow Agent, upon receipt of such sum from the Placement
Agents, to confirm such receipt by executing and delivering to the Pass Through
Trustee an Escrow Receipt in the form of Exhibit A hereto (an "Escrow
Receipt"), (a) to be affixed by the Pass Through Trustee to each Certificate
and (b) to evidence the same percentage interest (the "Escrow Interest") in the
Account Amounts (as defined below) as the Fractional Undivided Interest in the
Pass Through Trust evidenced by the Certificate to which it is to be affixed.
The Escrow Agent shall provide to the Pass Through Trustee for attachment to
each Certificate newly issued under and in accordance with the Pass Through
Trust Agreement an executed Escrow Receipt as the Pass Through Trustee may from
time to time request of the Escrow Agent.  Each Escrow Receipt shall be
registered by the Escrow Agent in a register (the "Register") maintained by the
Escrow Agent in the same name and same manner as the Certificate to which it is
attached and may not thereafter be detached from such Certificate to which it
is to be affixed prior to the distribution of the Final Withdrawal (the "Final
Distribution").  After the Final Distribution, no additional Escrow Receipts
shall be issued and the Pass Through Trustee shall request the return to the
Escrow Agent for cancellation of all outstanding Escrow Receipts.

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

                 Section 1.05.    Mutilated, Destroyed, Lost or Stolen Escrow
Receipt.  If (a) any mutilated Escrow Receipt is surrendered to the Escrow
Agent or the Escrow Agent receives evidence to its satisfaction of the
destruction, loss or theft of any Escrow Receipt and (b) there is delivered to
the Escrow Agent and the Pass Through Trustee such security, indemnity or bond,
as may be required by them to hold each of them harmless, then, absent notice
to the Escrow Agent or the Pass Through Trustee that such destroyed, lost or
stolen Escrow Receipt has been acquired by a bona fide purchaser, and provided
that the





                                       4
<PAGE>   8
requirements of Section 8-405 of the Uniform Commercial Code in effect in any
applicable jurisdiction are met, the Escrow Agent shall execute, authenticate
and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost
or stolen Escrow Receipt, a new Escrow Receipt or Escrow Receipts and of like
Escrow Interest in the Account Amounts and bearing a number not
contemporaneously outstanding.

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

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

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

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

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





                                       5
<PAGE>   9
Standard & Poor's Rating Group, a division of McGraw-Hill Inc., and Fitch IBCA,
Inc. that the replacement of the Escrow Agent with the successor Escrow Agent
will not result in (a) a reduction of the rating for the Certificates below the
then current rating for the Certificates or (b) a withdrawal or suspension of
the rating of the Certificates.

                 Section 1.08.    Persons Deemed Owners.  Prior to due
presentment of a Certificate for registration of transfer, the Escrow Agent and
the Paying Agent may treat the Person in whose name any Escrow Receipt is
registered (as of the day of determination) as the owner of such Escrow Receipt
for the purpose of receiving distributions pursuant to this Agreement and for
all other purposes whatsoever, and neither the Escrow Agent nor the Paying
Agent shall be affected by any notice to the contrary.

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

                 SECTION 2.       Paying Agent.

                 Section 2.01.    Appointment of Paying Agent.  The Escrow
Agent hereby irrevocably appoints and authorizes the Paying Agent to act as its
paying agent hereunder, for the benefit of the Investors, for such specific
purposes and with such powers as are specifically delegated to the Paying Agent
by the terms of this Agreement, together with such other powers as are
reasonably incidental thereto.  Any and all money received and held by the
Paying Agent under this Agreement or the Deposit Agreement shall be held in the
Paying Agent Account for the benefit of the Investors.   The Paying Agent
(which term as used in this sentence shall include reference to its affiliates
and its own and its affiliates' officers, directors, employees and agents):
(a) shall have no duties or responsibilities except those expressly set forth
in this Agreement, and shall not by reason of this Agreement be a trustee for
the Escrow Agent; (b) shall not be responsible to the Escrow Agent for any
recitals, statements, representations or warranties of any person other then
itself contained in this Agreement or for the failure by the Escrow Agent or
any other person or entity (other than the Paying Agent) to perform any of its
obligations hereunder (whether or not the Paying Agent shall have any knowledge
thereof); and (c) shall not be responsible for any action taken or omitted to
be taken by it hereunder or provided for herein or in connection herewith,
except for its own willful misconduct or gross negligence (or simple negligence
in connection with the handling of funds).

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





                                       6
<PAGE>   10
                 Section 2.03.    Payments from Paying Agent Account.  The
Escrow Agent hereby irrevocably instructs the Paying Agent, and the Paying
Agent agrees to act, as follows:

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

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

                 (c)      If any payment of interest or principal in respect of
         the Final Withdrawal is not received by the Paying Agent within five
         days of the applicable date when due, then it shall be distributed to
         Receiptholders after actual receipt by the Paying Agent on the same
         basis as a Special Payment is distributed under the Pass Through Trust
         Agreement.

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

                 Section 2.04.    Withholding Taxes.  The Paying Agent shall
exclude and withhold from each distribution of accrued interest on the Deposits
(as defined in the Deposit Agreement) and any amount in respect of the Final
Withdrawal any and all withholding taxes





                                       7
<PAGE>   11
applicable thereto as required by law.  The Paying Agent agrees to act as such
withholding agent and, in connection therewith, whenever any present or future
taxes or similar charges are required to be withheld with respect to any
amounts payable in respect of the Deposits (as defined in the Deposit
Agreement) or the escrow amounts, to withhold such amounts and timely pay the
same to the appropriate authority in the name of and on behalf of the
Receiptholders, that it will file any necessary withholding tax returns or
statements when due, and that, as promptly as possible after the payment
thereof, it will deliver to each such Receiptholder appropriate documentation
showing the payment thereof, together with such additional documentary evidence
as such Receiptholder may reasonably request from time to time.  The Paying
Agent agrees to file any other information reports as it may be required to
file under United States law.

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

                 Section 2.06.    Notice of Final Withdrawal.  Promptly after
receipt by the Paying Agent of notice that the Escrow Agent has requested a
Final Withdrawal or that a Final Withdrawal will be made, the Paying Agent
shall cause notice of the distribution of the Final Withdrawal to be mailed to
each of the Receiptholders at its address as it appears in the Register.  Such
notice shall be mailed not less than 15 days prior to the Final Withdrawal
Date.  Such notice shall set forth:

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

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





                                       8
<PAGE>   12
                 (iii)    if the Final Withdrawal Date is the same date as a
         Regular Distribution Date, the total amount to be received on such
         date for each $1,000 face amount Certificate (based on information
         provided by the Pass Through Trustee).

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

                 SECTION 3.       Payments.  If, notwithstanding the
instructions in Section 4 of the Deposit Agreement that all amounts payable to
the Escrow Agent under the Deposit Agreement be paid by the Depositary directly
to the Paying Agent or the Pass Through Trustee (depending on the
circumstances), the Escrow Agent receives any payment thereunder, then the
Escrow Agent shall forthwith pay such amount in Dollars and in immediately
available funds by wire transfer to (a) in the case of a payment of accrued
interest on the Deposits (as defined in the Deposit Agreement) or any Final
Withdrawal, directly to the Paying Agent Account and (b) in the case of any
Purchase Withdrawal, directly to the Pass Through Trustee or its designee as
specified and in the manner provided in the Applicable Notice of Purchase
Withdrawal.  The Escrow Agent hereby waives any and all rights of set-off,
combination of accounts, right of retention or similar right (whether arising
under applicable law, contract or otherwise) it may have against amounts
payable to the Paying Agent howsoever arising.

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

                 SECTION 5.       Representations and Warranties of the Escrow
Agent.  The Escrow Agent represents and warrants to Atlas, the Investors, the

expressly required of the Escrow Agent or the Paying Agent hereunder, each of
the Escrow Agent and the Paying Agent shall in all cases be fully justified in
failing or refusing to act hereunder unless it shall have been indemnified by
the party requesting such action in a manner reasonably satisfactory to it

                                     No. __

                 This Escrow Receipt evidences a fractional undivided interest
in amounts ("Account Amounts") from time to time deposited into a certain
paying agent account (the "Paying Agent Account") described in the Escrow and
Paying Agent Agreement (Class C) dated as of February 9, 1998 (as amended,
modified or supplemented from time to time, the "Escrow and Paying Agent
Agreement") among First Security Bank, National Association, as Escrow Agent
(in such capacity, together with its successors in such capacity, the "Escrow
Agent"), Morgan Stanley & Co. Incorporated, BT Alex. Brown Incorporated,
Donaldson, Lufkin Jenrette Securities Corporation and Goldman, Sachs & Co., as
Placement Agents, Wilmington Trust Company as Pass Through Trustee (in such
capacity, together with its successors in such capacity, the "Pass Through
Trustee") and Wilmington Trust Company, as paying agent (in such capacity,
together with its successors in such capacity, the "Paying Agent").
Capitalized terms not defined herein shall have the meanings assigned to them
in the Escrow and Paying Agent Agreement.

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

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

                 All payments and distributions made to Receiptholders in
respect of the Escrow Receipt shall be made only from Account Amounts deposited
in the Paying Agent Account.  The holder of this Escrow Receipt, by its
acceptance of this Escrow Receipt, agrees that it will look solely to the
Account Amounts for any payment or distribution due to it pursuant to this
Escrow Receipt and that it will not have any recourse to Atlas, the Pass
Through Trustee, the Paying Agent or the Escrow Agent, except as expressly
provided herein or in the Pass Through Trust Agreement.  No Receiptholder of
this Escrow Receipt shall have any right to vote or in any manner otherwise
control the operation and management of the Paying Agent Account, nor shall
anything set forth herein, or contained in the terms of this Escrow Receipt, be
construed so as to constitute the Receiptholders from time to time as partners
or members of an association.
<PAGE>   21
                 This Escrow Receipt may not be assigned or transferred except
in connection with the assignment or transfer of the Certificate to which this
Escrow Receipt is affixed.  After payment to the holder hereof of its Escrow
Interest in the Final Distribution, upon the request of the Pass Through
Trustee, the holder hereof will return this Escrow Receipt to the Pass Through
Trustee.

                 The Paying Agent may treat the person in whose name the
Certificate to which this Escrow Receipt is attached as the owner hereof for
all purposes, and the Paying Agent shall not be affected by any notice to the
contrary.

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

                 IN WITNESS WHEREOF, the Escrow Agent has caused this Escrow
Receipt to be duly executed.

                 Section 2.01.  The Advances.  The Liquidity Provider hereby
irrevocably agrees, on the terms  and conditions hereinafter set forth, to make
Advances to the Borrower from time to time on any Business Day during the
period from the Effective Date until 12:00 Noon (New York City time) on the

terminated in accordance with the terms of Section 2.04(b)) in an aggregate
amount at any time outstanding not to exceed the Maximum Commitment.

                 Section 2.02.  Making the Advances.  (a)  Interest Advances
shall be made in one or more Borrowings by delivery to the Liquidity Provider
of one or more written and completed Notices of Borrowing in substantially the
form of Annex I attached hereto, signed by a Responsible Officer of the
Borrower, in an amount not exceeding the Maximum Commitment at such time and
shall be used solely for the payment when due of the interest on the Class A
Certificates at the Stated Interest Rate therefor in accordance with Section
3.6(a) of the Intercreditor Agreement.  Each Interest Advance made hereunder
shall
<PAGE>   13
                                       9

automatically reduce the Maximum Commitment and the amount available to be
borrowed hereunder by subsequent Advances by the amount of such Interest
Advance (subject to reinstatement as provided in the next sentence).  Upon
repayment to the Liquidity Provider in full of the amount of any Interest
Advance made pursuant to this Section 2.02(a), together with accrued interest
thereon (as provided herein), the Maximum Commitment shall be reinstated by the
amount of such repaid Interest Advance; provided, however, that the Maximum
Commitment shall not be so reinstated at any time if (i) a Liquidity Event of
Default shall have occurred and be continuing and (ii) there is a Performing
Note Deficiency.

                 (b)      A Non-Extension Advance shall be made in a single
Borrowing if this Agreement is not extended in accordance with Section 3.6(d)
of the Intercreditor Agreement (unless a Replacement Liquidity Facility to
replace this Agreement shall have been delivered to the Borrower as
contemplated by said Section 3.6(d) within the time period specified in such
Section by delivery to the Liquidity Provider of a written and completed Notice
of Borrowing in substantially the form of Annex II attached hereto, signed by a
Responsible Officer of the Borrower, in an amount equal to the Maximum
Commitment at such time, and shall be used to fund the Class A Cash Collateral
Account in accordance with said Section 3.6(d) and Section 3.6(f) of the
Intercreditor Agreement.

                 (c)      A Downgrade Advance shall be made in a single
Borrowing upon a downgrading of the Liquidity Provider's short-term unsecured
debt rating issued by either Rating Agency below the applicable Threshold
Rating (as provided for in Section 3.6(c) of the Intercreditor Agreement)
unless a Replacement Liquidity Facility to replace this Agreement shall have
been previously delivered to the Borrower in accordance with said Section
3.6(c), by delivery to the Liquidity Provider of a written and completed Notice
of Borrowing in substantially the form of Annex III attached hereto, signed by
a Responsible Officer of the Borrower, in an amount equal to the Maximum
Commitment at such time, and shall be used to fund the Class A Cash Collateral
Account in accordance with said Section 3.6(c) and Section 3.6(f) of the
Intercreditor Agreement.

                 (d)      A Final Advance shall be made in a single Borrowing
upon the receipt by the Borrower of a Termination Notice from the Liquidity
Provider pursuant to Section 6.01 hereof by delivery to the Liquidity Provider
of a written and completed Notice of Borrowing in substantially the form of
Annex IV attached hereto, signed by a Responsible Officer of the Borrower, in
an amount equal to the Maximum Commitment at such time, and shall be used to
fund the Class A Cash Collateral Account (in accordance with Section 3.6(i) of
the Intercreditor Agreement) and Section 3.6(f) of the Intercreditor Agreement.

                 (e)      Each Borrowing shall be made on notice in writing (a
"Notice of Borrowing") in substantially the form required by Section 2.02(a),
2.02(b), 2.02(c) or 2.02(d), as the case may be, given by the Borrower to the
Liquidity Provider.  If a Notice of Borrowing is delivered by the Borrower in
respect of any Borrowing no later than 12:00
<PAGE>   14
                                       10

Noon (New York City time) on a Business Day, upon satisfaction of the
conditions precedent set forth in Section 4.02 with respect to a requested
Borrowing, the Liquidity Provider shall make available to the Borrower, in
accordance with its payment instructions, the amount of such Borrowing in U.S.
dollars and immediately available funds, before 12:00 Noon (New York City time)
on the first Business Day next following the day of receipt of such Notice of
Borrowing or on such later Business Day specified in such Notice of Borrowing.
If a Notice of Borrowing is delivered by the Borrower in respect of any
Borrowing after 12:00 Noon (New York City time) on a Business Day, upon
satisfaction of the conditions precedent set forth in Section 4.02 with respect
to a requested Borrowing, the Liquidity Provider shall make available to the
Borrower, in accordance with its payment instructions, the amount of such
Borrowing in U.S. dollars and immediately available funds, before 12:00 Noon
(New York City time) on the second Business Day next following the day of
receipt of such Notice of Borrowing or on such later Business Day specified by
the Borrower in such Notice of Borrowing.  Payments of proceeds of a Borrowing
shall be made by wire transfer of immediately available funds to the Borrower
in accordance with such wire transfer instructions as the Borrower shall
furnish from time to time to the Liquidity Provider for such purpose.  Each
Notice of Borrowing shall be irrevocable and binding on the Borrower.

                 (f)      Upon the making of any Advance requested pursuant to
a Notice of Borrowing, in accordance with the Borrower's payment instructions,
the Liquidity Provider shall be fully discharged of its obligation hereunder
with respect to such Notice of Borrowing, and the Liquidity Provider shall not
thereafter be obligated to make any further Advances hereunder in respect of
such Notice of Borrowing to the Borrower or to any other Person.  Following the
making of any Advance pursuant to Section 2.02(b), (c) or (d) hereof to fund
the Class A Cash Collateral Account, the Liquidity Provider shall have no
interest in or rights to the Class A Cash Collateral Account, such Advance or
any other amounts from time to time on deposit in the Class A Cash Collateral
Account; provided that the foregoing shall not affect or impair the obligations
of the Subordination Agent to make the distributions contemplated by Section
3.6(e) or (f) of the Intercreditor Agreement.  By paying to the Borrower
proceeds of Advances requested by the Borrower in accordance with the
provisions of this Agreement, the Liquidity Provider makes no representation as
to, and assumes no responsibility for, the correctness or sufficiency for any
purpose of the amount of the Advances so made and requested.

                 Section 2.03.  Fees.  The Borrower agrees to pay to the
Liquidity Provider the fees set forth in the ABN AMRO Fee Letter.

                 Section 2.04.  Reduction or Termination of the Maximum
Commitment.  (a)  Automatic Reduction.  Promptly following each date on which
the Required Amount is reduced as a result of a reduction in the Pool Balance
of the Class A Certificates or otherwise, the Maximum Commitment shall
automatically be reduced to an amount equal to such reduced Required Amount (as
calculated by the Borrower).  The Borrower shall give
<PAGE>   15
                                       11

notice of any such automatic reduction of the Maximum Commitment to the
Liquidity Provider within two Business Days thereof.  The failure by the
Borrower to furnish any such notice shall not affect such automatic reduction
of the Maximum Commitment.

                 (b)      Termination.  Upon the making of any Provider Advance
or Final Advance hereunder or the occurrence of the Termination Date, the
obligation of the Liquidity Provider to make further Advances hereunder shall
automatically and irrevocably terminate, and the Borrower shall not be entitled
to request any further Borrowing hereunder.

                 Section 2.05.  Repayments of Interest Advances or the Final
Advance.  Subject to Sections 2.06, 2.07 and 2.09 hereof, the Borrower hereby
agrees, without notice of an Advance or demand for repayment from the Liquidity
Provider (which notice and demand are hereby waived by the Borrower), to pay,
or to cause to be paid, to the Liquidity Provider on each date on which the
Liquidity Provider shall make an Interest Advance or the Final Advance, an
amount equal to (a) the amount of such Advance (any such Advance, until repaid,
is referred to herein as an "Unpaid Advance"), plus (b) interest on the amount
of each such Unpaid Advance as provided in Section 3.07 hereof; provided that
if (i) the Liquidity Provider shall make a Provider Advance at any time after
making one or more Interest Advances which shall not have been repaid in
accordance with this Section 2.05 or (ii) this Liquidity Facility shall become
a Downgraded Facility or Non-Extended Facility at any time when unreimbursed
Interest Advances have reduced the Maximum Commitment to zero, then such
Interest Advances shall cease to constitute Unpaid Advances and shall be deemed
to have been changed into an Applied Downgrade Advance or an Applied
Non-Extension Advance, as the case may be, for all purposes of this Agreement
(including, without limitation, for the purpose of determining when such
Interest Advance is required to be repaid to the Liquidity Provider in
accordance with Section 2.06 and for the purposes of Section 2.06(b)). The
Borrower and the Liquidity Provider agree that the repayment in full of each
Interest Advance and Final Advance on the date such Advance is made is intended
to be a contemporaneous exchange for new value given to the Borrower by the
Liquidity Provider.

                 Section 2.06.  Repayments of Provider Advances.  (a)  Amounts
advanced hereunder in respect of a Provider Advance shall be deposited in the
Class A Cash Collateral Account, invested and withdrawn from the Class A Cash
Collateral Account as set forth in Sections 3.6(c), (d) and (f) of the
Intercreditor Agreement.  The Borrower agrees to pay to the Liquidity Provider,
on each Regular Distribution Date, commencing on the first Regular Distribution
Date after the making of a Provider Advance, interest on the principal amount
of any such Provider Advance as provided in Section 3.07; provided, however,
that amounts in respect of a Provider Advance withdrawn from the Class A Cash
Collateral Account for the purpose of paying interest on the Class A
Certificates in accordance with Section 3.6(f) of the Intercreditor Agreement
(the amount of any such withdrawal being (y) in the case of a Downgrade
Advance, an "Applied Downgrade Advance" and (z) in the case of a Non-Extension
Advance, an "Applied Non-Extension Advance" and, together with an Applied
<PAGE>   16
                                       12

Downgrade Advance, an "Applied Provider Advance") shall thereafter (subject to
Section 2.06(b)) be treated as an Interest Advance under this Agreement for
purposes of determining the Applicable Liquidity Rate for interest payable
thereon; provided further, however, that if, following the making of a Provider
Advance, the Liquidity Provider delivers a Termination Notice to the Borrower
pursuant to Section 6.01 hereof, such Provider Advance shall thereafter be
treated as a Final Advance under this Agreement for purposes of determining the
Applicable Liquidity Rate for interest payable thereon.  Subject to Sections
2.07 and 2.09 hereof, immediately upon the withdrawal of any amounts from the
Class A Cash Collateral Account on account of a reduction in the Required
Amount, the Borrower shall repay to the Liquidity Provider a portion of the
Provider Advances in a principal amount equal to such reduction, plus interest
on the principal amount prepaid as provided in Section 3.07 hereof.

                 (b)      At any time when an Applied Provider Advance (or any
portion thereof) is outstanding, upon the deposit in the Class A Cash
Collateral Account of any amount pursuant to clause "third" of Section 2.4(b)
of the Intercreditor Agreement, clause "third" of Section 3.2 of the
Intercreditor Agreement or clause "fourth" of Section 3.3 of the Intercreditor
Agreement (any such amount being a "Replenishment Amount") for the purpose of
replenishing or increasing the balance thereof up to the Required Amount at
such time, (i) the aggregate outstanding principal amount of all Applied
Provider Advances (and of Provider Advances treated as an Interest Advance for
purposes of determining the Applicable Liquidity Rate for interest payable
thereon) shall be automatically reduced by the amount of such Replenishment
Amount and (ii) the aggregate outstanding principal amount of all Unapplied
Provider Advances shall be automatically increased by the amount of such
Replenishment Amount.

                 (c)      Upon the provision of a Replacement Liquidity
Facility in replacement of this Agreement in accordance with Section 3.6(e) of
the Intercreditor Agreement, amounts remaining on deposit in the Class A Cash
Collateral Account after giving effect to any Applied Provider Advance on the
date of such replacement shall be reimbursed to the Liquidity Provider, but
only to the extent such amounts are necessary to repay in full to the Liquidity
Provider all amounts owing to it hereunder.

                 Section 2.07.  Payments to the Liquidity Provider Under the
Intercreditor Agreement.  In order to provide for payment or repayment to the
Liquidity Provider of any amounts hereunder, the Intercreditor Agreement
provides that amounts available and referred to in Articles II and III of the
Intercreditor Agreement, to the extent payable to the Liquidity Provider
pursuant to the terms of the Intercreditor Agreement (including, without
limitation, Section 3.6(f) of the Intercreditor Agreement), shall be paid to
the Liquidity Provider in accordance with the terms thereof.  Amounts so paid
to the Liquidity Provider shall be applied by the Liquidity Provider to
Liquidity Obligations then due and payable in accordance with the Intercreditor
Agreement or, if not provided for in the Intercreditor Agreement, then in such
manner as the Liquidity Provider shall deem appropriate.

                                       13


                 Section 2.08.  Book Entries.  The Liquidity Provider shall
maintain in accordance with its usual practice an account or accounts
evidencing the indebtedness of the Borrower resulting from Advances made from
time to time and the amounts of principal and interest payable hereunder and
paid from time to time in respect thereof; provided, however, that the failure
by the Liquidity Provider to maintain such account or accounts shall not affect
the obligations of the Borrower in respect of Advances.

                 Section 2.09.  Payments from Available Funds Only.  All
payments to be made by the Borrower under this Agreement shall be made only
from the amounts that constitute Scheduled Payments, Special Payments or
payments under Section 8.1 or 9.1, as the case may be, of the Participation
Agreements and Section 6 of the Note Purchase Agreement and only to the extent
that the Borrower shall have sufficient income or proceeds therefrom to enable
the Borrower to make payments in accordance with the terms hereof after giving
effect to the priority of payments provisions set forth in the Intercreditor
Agreement.  The Liquidity Provider agrees that it will look solely to such
amounts to the extent available for distribution to it as provided in the
Intercreditor Agreement and this Agreement and that the Borrower, in its
individual capacity, is not personally liable to it for any amounts payable or
liability under this Agreement except as expressly provided in this Agreement,
the Intercreditor Agreement or any Participation Agreement.  Amounts on deposit
in the Class A Cash Collateral Account shall be available to the Borrower to
make payments under this Agreement only to the extent and for the purposes
expressly contemplated in Section 3.6(f) of the Intercreditor Agreement.

                 Section 2.10.  Extension of the Expiry Date:  Non-Extension
Advance.  No earlier than the 60th day and no later than the 40th day prior to
the then effective Expiry Date (unless such Expiry Date is on or after the date
that is 15 days after the Final Maturity Date for the Class A Certificates),
the Borrower shall request that the Liquidity Provider extend the Expiry Date
for a period of 364 days after the then effective Expiry Date (unless the
obligations of the Liquidity Provider are earlier terminated in accordance with
the terms hereof).  The Liquidity Provider shall advise the Borrower, no
earlier than 40 days and no later than 25 days prior to the then effective
Expiry Date, whether, in its sole discretion, it agrees to so extend the Expiry
Date.  If the Liquidity Provider advises the Borrower on or before the 25th day
prior to the Expiry Date then in effect that such Expiry Date shall not be so
extended, or fails to irrevocably and unconditionally advise the Borrower on or
before the 25th day prior to the Expiry Date then in effect that such Expiry
Date shall be so extended (and, in each case, if the Liquidity Provider shall
not have been replaced in accordance with Section 3.6(e) of the Intercreditor
Agreement), the Borrower shall be entitled on and after such 25th day (but
prior to the then effective Expiry Date) to request a Non-Extension Advance in
accordance with Section 2.02(b) hereof and Section 3.6(d) of the Intercreditor
Agreement.

                                  ARTICLE III

                          OBLIGATIONS OF THE BORROWER

                 Section 3.01.  Increased Costs.  The Borrower shall pay to the
Liquidity Provider from time to time such amounts as may be necessary to
compensate the Liquidity Provider for any increased costs incurred by the
Liquidity Provider which are attributable to its making or maintaining any
LIBOR Advances hereunder or its obligation to make any such Advances hereunder,
or any reduction in any amount receivable by the Liquidity Provider under this
Agreement or the Intercreditor Agreement in respect of any such Advances or
such obligation (such increases in costs and reductions in amounts receivable
being herein called "Additional Costs"), resulting from any change after the
date of this Agreement in U.S. federal, state, municipal, or foreign laws or
regulations (including Regulation D of the Board of Governors of the Federal
Reserve System), or the adoption or making after the date of this Agreement of
any interpretations, directives, or requirements applying to a class of banks
including the Liquidity Provider under any U.S. federal, state, municipal, or
any foreign laws or regulations (whether or not having the force of law) by any
court, central bank or monetary authority charged with the interpretation or
administration thereof (a "Regulatory Change"), which: (1) changes the basis of
taxation of any amounts payable to the Liquidity Provider under this Agreement
in respect of any such Advances (other than Excluded Taxes); or (2) imposes or
modifies any reserve, special deposit, compulsory loan or similar requirements
relating to any extensions of credit or other assets of, or any deposits with
other liabilities of, the Liquidity Provider (including any such Advances or
any deposits referred to in the definition of LIBOR Rate or related
definitions).  The Liquidity Provider agrees to use reasonable efforts
(consistent with applicable legal and regulatory restrictions) to change the
jurisdiction of its Lending Office if making such change would avoid the need
for, or reduce the amount of, any amount payable under this Section that may
thereafter accrue and would not, in the reasonable judgment of the Liquidity
Provider, be otherwise disadvantageous to the Liquidity Provider.

                 The Liquidity Provider will notify the Borrower of any event
occurring after the date of this Agreement that will entitle the Liquidity
Provider to compensation pursuant to this Section 3.01 as promptly as
practicable after it obtains knowledge thereof and determines to request such
compensation, which notice shall describe in reasonable detail the calculation
of the amounts owed under this Section.  Determinations by the Liquidity
Provider for purposes of this Section 3.01 of the effect of any Regulatory
Change on its costs of making or maintaining Advances or on amounts receivable
by it in respect of Advances, and of the additional amounts required to
compensate the Liquidity Provider in respect of any Additional Costs, shall be
prima facie evidence of the amount owed under this Section.

                 Section 3.02.  Capital Adequacy.  If (1) the adoption, after
the date hereof, of any applicable governmental law, rule or regulation
regarding capital adequacy, (2) any
<PAGE>   19
                                       15

change, after the date hereof, in the interpretation or administration of any
such law, rule or regulation by any central bank or other governmental
authority charged with the interpretation or administration thereof or (3)
compliance by the Liquidity Provider or any corporation controlling the
Liquidity Provider with any applicable guideline or request of general
applicability, issued after the date hereof, by any central bank or other
governmental authority (whether or not having the force of law) that
constitutes a change of the nature described in clause (2), has the effect of
requiring an increase in the amount of capital required to be maintained by the
Liquidity Provider or any corporation controlling the Liquidity Provider, and
such increase is based upon the Liquidity Provider's obligations hereunder and
other similar obligations, the Borrower shall pay to the Liquidity Provider
from time to time such additional amount or amounts as are necessary to
compensate the Liquidity Provider for such portion of such increase as shall be
reasonably allocable to the Liquidity Provider's obligations to the Borrower
hereunder.  The Liquidity Provider agrees to use reasonable efforts (consistent
with applicable legal and regulatory restrictions) to change the jurisdiction
of its Lending Office if making such change would avoid the need for, or reduce
the amount of, any amount payable under this Section that may thereafter accrue
and would not, in the reasonable judgment of the Liquidity Provider, be
otherwise materially disadvantageous to the Liquidity Provider.

                 The Liquidity Provider will notify the Borrower of any event
occurring after the date of this Agreement that will entitle the Liquidity
Provider to compensation pursuant to this Section 3.02 as promptly as
practicable after it obtains knowledge thereof and determines to request such
compensation, which notice shall describe in reasonable detail the calculation
of the amounts owed under this Section.  Determinations by the Liquidity
Provider for purposes of this Section 3.02 of the effect of any increase in the
amount of capital required to be maintained by the bank and of the amount
allocable to the Liquidity Provider's obligations to the Borrower hereunder
shall be prima facie evidence of the amounts owed under this Section.

                 Section 3.03.  Payments Free of Deductions.  All payments made
by the Borrower under this Agreement shall be made free and clear of, and
without reduction for or on account of, any present or future stamp or other
taxes, levies, imposts, duties, charges, fees, deductions, withholdings,
restrictions or conditions of any nature whatsoever now or hereafter imposed,
levied, collected, withheld or assessed, excluding Excluded Taxes (such
non-excluded taxes being referred to herein, collectively, as "Non-Excluded
Taxes" and, individually, as a "Non-Excluded Tax").  If any Non-Excluded Taxes
are required to be withheld from any amounts payable to the Liquidity Provider
under this Agreement, the amounts so payable to the Liquidity Provider shall be
increased to the extent necessary to yield to the Liquidity Provider (after
payment of all Non-Excluded Taxes) interest or any other such amounts payable
under this Agreement at the rates or in the amounts specified in this
Agreement.  The Liquidity Provider agrees to use reasonable efforts (consistent
with its internal policy and legal and regulatory restrictions) to change the
jurisdiction of its Lending
<PAGE>   20
                                       16

Office if making such change would avoid the need for, or reduce the amount of,
any such additional amounts that may thereafter accrue and would not, in the
reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to
the Liquidity Provider.  From time to time upon the reasonable request of the
Borrower, the Liquidity Provider agrees to provide to the Borrower two original
Internal Revenue Service Forms 1001 or 4224, as appropriate, or any successor
or other form prescribed by the Internal Revenue Service, certifying that the
Liquidity Provider is exempt from or entitled to a reduced rate of United
States withholding tax on payments pursuant to this Agreement.

                 (b)      All payments (including, without limitation,
Advances) made by the Liquidity Provider under this Agreement shall be made
free and clear of, and without reduction for or on account of, any Taxes.  If
any Taxes are required to be withheld or deducted from any amounts payable to
the Borrower under this Agreement, the Liquidity Provider shall (i) within the
time prescribed therefor by applicable law pay to the appropriate governmental
or taxing authority the full amount of any such Taxes (and any additional Taxes
in respect of the payment required under clause (ii) hereof) and make such
reports or returns in connection therewith at the time or times and in the
manner prescribed by applicable law, and (ii) pay to the Borrower an additional
amount which (after deduction of all such Taxes) will be sufficient to yield to
the Borrower the full amount which would have been received by it had no such
withholding or deduction been made.  Within 30 days after the date of each
payment hereunder, the Liquidity Provider shall furnish to the Borrower the
original or a certified copy of (or other documentary evidence of) the payment
of the Taxes applicable to such payment.

                 Section 3.04.  Payments.  The Borrower shall make or cause to
be made each payment to the Liquidity Provider under this Agreement so as to
cause the same to be received by the Liquidity Provider not later than 1:00
P.M.  (New York City time) on the day when due.  The Borrower shall make all
such payments in lawful money of the United States of America, to the Liquidity
Provider in immediately available funds, by wire transfer to ABN AMRO Bank New
York, NY, ABA # 026009580, Account Name: ABN AMRO Bank N.V., Chicago Branch,
Account # 650-001-1789-41, Reference: Atlas Air, Inc., 1998-1A.

                 Section 3.05.  Computations.  All computations of interest
based on the Base Rate shall be made on the basis of a year of 365 or 366 days,
as the case may be, and all computations of interest based on the LIBOR Rate
shall be made on the basis of a year of 360 days, in each case for the actual
number of days (including the first day but excluding the last day) occurring
in the period for which such interest is payable.

                 Section 3.06.  Payment on Non-Business Days.  Whenever any
payment to be made hereunder shall be stated to be due on a day other than a
Business Day, such payment shall be made on the next succeeding Business Day
and no additional interest shall be due as a result (and if so made, shall be
deemed to have been made when due).  If any payment in
<PAGE>   21
                                       17

respect of interest on an Advance is so deferred to the next succeeding
Business Day, such deferral shall not delay the commencement of the next
Interest Period for such Advance (if such Advance is a LIBOR Advance) or reduce
the number of days for which interest will be payable on such Advance on the
next interest payment date for such Advance.

                 Section 3.07.  Interest.  (a)  Subject to Section 2.09, the
Borrower shall pay, or shall cause to be paid, without duplication, interest on
(i) the unpaid principal amount of each Advance from and including the date of
such Advance (or, in the case of an Applied Provider Advance, from and
including the date on which the amount thereof was withdrawn from the Class A
Cash Collateral Account to pay interest on the Class A Certificates) to but
excluding the date such principal amount shall be paid in full (or, in the case
of an Applied Provider Advance, the date on which the Class A Cash Collateral
Account is fully replenished in respect of such Advance) and (ii) any other
amount due hereunder (whether fees, commissions, expenses or other amounts or,
to the extent permitted by law, installments of interest on Advances or any
such other amount) which is not paid when due (whether at stated maturity, by
acceleration or otherwise) from and including the due date thereof to but
excluding the date such amount is paid in full, in each such case, at a
fluctuating interest rate per annum for each day equal to the Applicable
Liquidity Rate (as defined below) for such Advance or such other amount as in
effect for such day, but in no event at a rate per annum greater than the
maximum rate permitted by applicable law; provided, however, that, if at any
time the otherwise applicable interest rate as set forth in this Section 3.07
shall exceed the maximum rate permitted by applicable law, then any subsequent
reduction in such interest rate will not reduce the rate of interest payable
pursuant to this Section 3.07 below the maximum rate permitted by applicable
law until the total amount of interest accrued equals the amount of interest
that would have accrued if such otherwise applicable interest rate as set forth
in this Section 3.07 had at all times been in effect.

                 (b)      Except as provided in clause (e) below, each Advance
will be either a Base Rate Advance or a LIBOR Advance as provided in this
Section.  Each such Advance will be a Base Rate Advance for the period from the
date of its borrowing to (but excluding) the third Business Day following the
Liquidity Provider's receipt of the Notice of Borrowing for such Advance.
Thereafter, such Advance shall be a LIBOR Advance; provided that the Borrower
(at the direction of the Controlling Party), so long as the Liquidity Provider
is not the Controlling Party) may (x) convert the Final Advance into a Base
Rate Advance on the last day of an Interest Period for such Advance by giving
the Liquidity Provider no less than four Business Days' prior written notice of
such election or (y) elect to maintain the Final Advance as a Base Rate Advance
by not requesting a conversion of the Final Advance to a LIBOR Advance under
Clause (5) of the applicable Notice of Borrowing.

                 (c)      Each LIBOR Advance shall bear interest during each
Interest Period at a rate per annum equal to the LIBOR Rate for such Interest
Period plus the Applicable
<PAGE>   22
                                       18

Margin for such LIBOR Advance, payable in arrears on the last day of such
Interest Period and, in the event of the payment of principal of such LIBOR
Advance on a day other than such last day, on the date of such payment (to the
extent of interest accrued on the amount of principal repaid).

                 (d)      Each Base Rate Advance shall bear interest at a rate
per annum equal to the Base Rate plus the Applicable Margin for such Base Rate
Advance, payable in arrears on each Regular Distribution Date and, in the event
of the payment of principal of such Base Rate Advance on a day other than a
Regular Distribution Date, on the date of such payment (to the extent of
interest accrued on the amount of principal repaid).

                 (e)      Each Unapplied Downgrade Advance (i) during the
period from and including the date of the making of such Unapplied Downgrade
Advance through but excluding the Expiry Date (or, if earlier, the date of
repayment thereof or of conversion thereof into a Final Advance), shall bear
interest at a rate per annum equal to the LIBOR Rate for such Interest Period
plus 0.675% on the amount of such Unapplied Downgrade Advance from time to time
during such period, payable in arrears on each Regular Distribution Date and
(ii) thereafter, shall be a LIBOR Advance and shall bear interest in accordance
with clause (c) above.

                 (f)      Each Unapplied Non-Extension Advance (i) during the
period from and including the date of the making of such Unapplied
Non-Extension Advance through but excluding the date of conversion thereof into
a Final Advance, shall bear interest at a rate per annum equal to LIBOR for the
applicable Interest Period plus 0.475% on the amount of such Unapplied
Non-Extension Advance from time to time during such period, payable in arrears
on each Regular Distribution Date and (ii) thereafter, shall be a LIBOR Advance
and shall bear interest in accordance with clause (c) above.

                 (g)      Each amount not paid when due hereunder (whether
fees, commissions, expenses or other amounts or, to the extent permitted by
applicable law, installments of interest on Advances but excluding Advances)
shall bear interest at a rate per annum equal to the Base Rate plus 3.00% until
paid.

                 (h)      Each change in the Base Rate shall become effective
immediately.  The rates of interest specified in this Section 3.07 with respect
to any Advance or other amount shall be referred to as the "Applicable
Liquidity Rate".

                 Section 3.08.  Replacement of Borrower.  From time to time and
subject to the successor Borrower's meeting the eligibility requirements set
forth in Section 6.9 of the Intercreditor Agreement applicable to the
Subordination Agent, upon the effective date and time specified in a written
and completed Notice of Replacement Subordination Agent in substantially the
form of Annex VI attached hereto (a "Notice of Replacement Subordination
<PAGE>   23
                                       19

Agent") delivered to the Liquidity Provider by the then Borrower, the successor
Borrower designated therein shall be substituted for as the Borrower for all
purposes hereunder.

                 Section 3.09.  Funding Loss Indemnification.  The Borrower
shall pay to the Liquidity Provider, upon the request of the Liquidity
Provider, such amount or amounts as shall be sufficient (in the reasonable
opinion of the Liquidity Provider) to compensate it for any loss, cost, or
expense incurred by reason of the liquidation or redeployment of deposits or
other funds acquired by the Liquidity Provider to fund or maintain any LIBOR
Advance (but excluding loss of anticipated profits) incurred as a result of:

                 (1)      Any repayment of a LIBOR Advance on a date other than
         the last day of the Interest Period for such Advance; or

                 (2)      Any failure by the Borrower to borrow a LIBOR Advance
         on the date for borrowing specified in the relevant notice under
         Section 2.02.

                 Section 3.10.  Illegality.  Notwithstanding any other
provision in this Agreement, if any change in any applicable law, rule or
regulation, or any change in the interpretation or administration thereof by
any governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by the Liquidity
Provider (or its Lending Office) with any request or directive (whether or not
having the force of law) of any such authority, central bank or comparable
agency shall make it unlawful or impossible for the Liquidity Provider (or its
Lending Office) to maintain or fund its LIBOR Advances, then upon notice to the
Borrower by the Liquidity Provider, the outstanding principal amount of the
LIBOR Advances shall be converted to Base Rate Advances (a) immediately upon
demand of the Liquidity Provider, if such change or compliance with such
request, in the judgment of the Liquidity Provider, requires immediate
repayment; or (b) at the expiration of the last Interest Period to expire
before the effective date of any such change or request.

         such transactions and to meet with officers and employees of the
         Borrower to discuss such transactions.

                 (c)      Certain Operative Agreements.  Furnish to the
         Liquidity Provider with reasonable promptness, such Operative
         Agreements entered into after the date hereof  as from time to time
         may be reasonably requested by the Liquidity Provider.

any Advance shall remain unpaid or the Liquidity Provider shall have any
Maximum Commitment hereunder or the Borrower shall have any obligation to pay
any amount to the Liquidity Provider hereunder, the Borrower will not appoint
or permit or suffer to be appointed any successor Borrower without the prior
written consent of the Liquidity Provider, which consent shall not be
unreasonably withheld or delayed.

Liquidity Event of Default has occurred and is continuing and (b) there is a

                 Section 7.03. No Waiver: Remedies.  No failure on the part of
the Liquidity Provider to exercise, and no delay in exercising, any right under
this Agreement shall operate as a waiver thereof; nor shall any single or
partial exercise of any right under this Agreement preclude any other or
further exercise thereof or the exercise of any other right.  The remedies
herein provided are cumulative and not exclusive of any remedies provided by
law.

                 Section 7.04.  Further Assurances.  The Borrower agrees to do
such further acts and things and to execute and deliver to the Liquidity
Provider such additional assignments, agreements, powers and instruments as the
Liquidity Provider may reasonably require or deem advisable to carry into
effect the purposes of this Agreement and the other Operative Agreements or to
better assure and confirm unto the Liquidity Provider its rights, powers and
remedies hereunder and under the other Operative Agreements.

                 Section 7.05.  Indemnification; Survival of Certain

extent and in the manner described in Section 9.1 of the Leased Aircraft
Participation Agreement, Section 8.1 of the Owned Aircraft Participation
Agreement and Section 6 of the Note Purchase Agreement.  In addition, the
Borrower agrees to indemnify, protect, defend and hold harmless the Liquidity
Provider from, against and in respect of, and shall pay on demand, all Expenses
of any kind or nature whatsoever (other than any Expenses of the nature
described in Sections 3.01, 3.02 or 7.07 hereof or in the ABN AMRO Fee Letter
(regardless of whether indemnified against pursuant to said Sections or in such
ABN AMRO Fee Letter)), that may be imposed, incurred by or asserted against any
Liquidity Indemnitee, in any way relating to, resulting from, or arising out of
or in connection with any action, suit or proceeding by any third party against
such
<PAGE>   29
                                       25

Liquidity Indemnitee and relating to this Agreement, the ABN AMRO Fee Letter,
the Intercreditor Agreement or any Financing Agreement; provided, however, that
the Borrower shall not be required to indemnify, protect, defend and hold
harmless any Liquidity Indemnitee in respect of any Expense of such Liquidity
Indemnitee to the extent such Expense is (i) attributable to the gross
negligence or willful misconduct of such Liquidity Indemnitee or any other
Liquidity Indemnitee, (ii) ordinary and usual operating overhead expense, or
(iii) attributable to the failure by such Liquidity Indemnitee or any other
Liquidity Indemnitee to perform or observe any agreement, covenant or condition
on its part to be performed or observed in this Agreement, the Intercreditor
Agreement, the ABN AMRO Fee Letter, the Tax Letter or any other Operative
Agreement to which it is a party.  The indemnities contained in Section 9.1 or
8.1, as the case may be, of the Participation Agreements, and the provisions of
Sections 3.01, 3.02, 3.03, 3.09, 7.05 and 7.07 hereof, shall survive the
termination of  this  Agreement.

                 Section 7.06.  Liability of the Liquidity Provider.  (a)
Neither the Liquidity Provider nor any of its officers, employees, directors or
affiliates shall be liable or responsible for: (i) the use which may be made of
the Advances or any acts or omissions of the Borrower or any beneficiary or
transferee in connection therewith; (ii) the validity, sufficiency or
genuineness of documents, or of any endorsement thereon, even if such documents
should prove to be in any or all respects invalid, insufficient, fraudulent or
forged; or (iii) the making of Advances by the Liquidity Provider against
delivery of a Notice of Borrowing and other documents which do not comply with
the terms hereof; provided, however, that the Borrower shall have a claim
against the Liquidity Provider, and the Liquidity Provider shall be liable to
the Borrower, to the extent of any damages suffered by the Borrower which were
the result of (A) the Liquidity Provider's willful misconduct or negligence in
determining whether documents presented hereunder comply with the terms hereof,
or (B) any breach by the Liquidity Provider of any of the terms of this
Agreement, including, but not limited to, the Liquidity Provider's failure to
make lawful payment hereunder after the delivery to it by the Borrower of a
Notice of Borrowing strictly complying with the terms and conditions hereof.

                 (b)      Neither the Liquidity Provider nor any of its
officers, employees, director or affiliates shall be liable or responsible in
any respect for (i) any error, omission, interruption or delay in transmission,
dispatch or delivery of any message or advice, however transmitted, in
connection with this Agreement or any Notice of Borrowing delivered hereunder,
or (ii) any action, inaction or omission which may be taken by it in good
faith, absent willful misconduct or negligence (in which event the extent of
the Liquidity Provider's potential liability to the Borrower shall be limited
as set forth in the immediately preceding paragraph), in connection with this
Agreement or any Notice of Borrowing.

                 Section 7.07.  Costs, Expenses and Taxes.  The Borrower agrees
to pay, or cause to be paid (A) on the Effective Date and on such later date or
dates on which the
<PAGE>   30
                                       26

Liquidity Provider shall make demand, all reasonable out-of-pocket costs and
expenses (including, without limitation, the reasonable fees and expenses of
outside counsel for the Liquidity Provider) of the Liquidity Provider in
connection with the preparation, negotiation, execution, delivery, filing and
recording of this Agreement, any other Operative Agreement and any other
documents which may be delivered in connection with this Agreement and (B) on
demand, all reasonable costs and expenses (including reasonable counsel fees
and expenses) of the Liquidity Provider in connection with (i) the enforcement
of this Agreement or any other Operative Agreement, (ii) the modification or
amendment of, or supplement to, this Agreement or any other Operative Agreement
or such other documents which may be delivered in connection herewith or
therewith (whether or not the same shall become effective) or (iii) any action
or proceeding relating to any order, injunction, or other process or decree
restraining or seeking to restrain the Liquidity Provider from paying any
amount under this Agreement, the Intercreditor Agreement or any other Operative
Agreement or otherwise affecting the application of funds in the Class A Cash
Collateral Account.  In addition, the Borrower shall pay any and all recording,
stamp and other similar taxes and fees payable or determined to be payable in
connection with the execution, delivery, filing and recording of this
Agreement, any other Operative Agreement and such other documents, and agrees
to save the Liquidity Provider harmless from and against any and all
liabilities with respect to or resulting from any delay in paying or omission
to pay such taxes or fees.

                 Section 7.08.  Binding Effect; Participations.

                 (a)      This Agreement shall be binding upon and inure to the
benefit of the Borrower and the Liquidity Provider and their respective
successors and assigns, except that neither the Liquidity Provider (except as
otherwise provided in this Section 7.08) nor (except as contemplated by Section
3.08) the Borrower shall have the right to assign its rights or obligations
hereunder or any interest herein without the prior written consent of the other
party, subject to the requirements of Section 7.08(b). The Liquidity Provider
may grant participations herein or in any of its rights hereunder (including,
without limitation, funded participations and participations in rights to
receive interest payments hereunder) and under the other Operative Agreements
to such Persons as the Liquidity Provider may in its sole discretion select,
subject to the requirements of Section 7.08(b). No such participation by the
Liquidity Provider, however, will relieve the Liquidity Provider of its
obligations hereunder.  In connection with any participation or any proposed
participation, the Liquidity Provider may disclose to the participant or the
proposed participant any information that the Borrower is required to deliver
or to disclose to the Liquidity Provider pursuant to this Agreement.  The
Borrower acknowledges and agrees that the Liquidity Provider's source of funds
may derive in part from its participants (other than Atlas).  Accordingly,
references in this Agreement and the other Operative Agreements to
determinations, reserve and capital adequacy requirements, increased costs,
reduced receipts, additional amounts due pursuant to Section 3.03(a) and the
like as they pertain to the Liquidity Provider shall be deemed also to include
those of each of its participants (subject, in each case, to the maximum amount
that
<PAGE>   31
                                       27

would have been incurred by or attributable to the Liquidity Provider directly
if the Liquidity Provider, rather than the participant, had held the interest
participated).

                 (b)      If, pursuant to subsection (a) above, the Liquidity
Provider sells any participation in this Agreement to any bank or other entity
(each, a "Transferee"), then, concurrently with the effectiveness of such
participation, the Transferee shall (i) represent to the Liquidity Provider
(for the benefit of the Liquidity Provider and the Borrower) either (A) that it
is incorporated under the laws of the United States or a state thereof or (B)
that under applicable law and treaties, no taxes will be required to be
withheld with respect to any payments to be made to such Transferee in respect
of this Agreement, (ii) furnish to the Liquidity Provider and the Borrower
either (x) a statement that it is incorporated under the laws of the United
States or a state thereof or (y) if it is not so incorporated, two copies of a
properly completed United States Internal Revenue Service Form 4224 or Form
1001, as appropriate, or other applicable form, certificate or document
prescribed by the Internal Revenue Service certifying, in each case, such
Transferee's entitlement to a complete exemption from United States federal
withholding tax in respect to any and all payments to be made hereunder, and
(iii) agree (for the benefit of the Liquidity Provider and the Borrower) to
provide the Liquidity Provider and the Borrower a new Form 4224 or Form 1001,
as appropriate, (A) on or before the date that any such form expires or becomes
obsolete or (B) after the occurrence of any event requiring a change in the
most recent form previously delivered by it and prior to the immediately
following due date of any payment by the Borrower hereunder, certifying in the
case of a Form 1001 or Form 4224 that such Transferee is entitled to a complete
exemption from United States federal withholding tax on payments under this
Agreement.  Unless the Borrower has received forms or other documents
reasonably satisfactory to it (and required by applicable law) indicating that
payments hereunder are not subject to United States federal withholding tax,
the Borrower will withhold taxes as required by law from such payments at the
applicable statutory rate.

                 (c)      Notwithstanding the other provisions of this Section
7.08, the Liquidity Provider may assign and pledge all or any portion of the
Advances owing to it to any Federal Reserve Bank or the United States Treasury
as collateral security pursuant to Regulation A of the Board of Governors of
the Federal Reserve System and any Operating Circular issued by such Federal
Reserve Bank, provided that any payment in respect of such assigned Advances
made by the Borrower to the Liquidity Provider in accordance with the terms of
this Agreement shall satisfy the Borrower's obligations hereunder in respect of
such assigned Advance to the extent of such payment.  No such assignment shall
release the Liquidity Provider from its obligations hereunder.

                 Section 7.09.  Severability.  Any provision of this Agreement
which is prohibited, unenforceable or not authorized in any jurisdiction shall,
as to such jurisdiction, be ineffective to the extent of such prohibition,
unenforceability or nonauthorization without
<PAGE>   32
                                       28

invalidating the remaining provisions hereof or affecting the validity,
enforceability or legality of such provision in any other jurisdiction.

                 Section 7.10.  GOVERNING LAW.  THIS AGREEMENT SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW
YORK.

                 Section 7.11.  Submission to Jurisdiction; Waiver of Jury
Trial; Waiver of Immunity.  (a)  Each of the parties hereto hereby irrevocably
and unconditionally:

         (i)     submits for itself and its property in any legal action or
                 proceeding relating to this Agreement or any other Operative
                 Agreement, or for recognition and enforcement of any judgment
                 in respect hereof or thereof, to the nonexclusive general
                 jurisdiction of the courts of the State of New York, the
                 courts of the United States of America for the Southern
                 District of New York, and the appellate courts from any
                 thereof;

         (ii)    consents that any such action or proceeding may be brought in
                 such courts, and waives any objection that it may now or
                 hereafter have to the venue of any such action or proceeding
                 in any such court or that such action or  proceeding was
                 brought in an inconvenient court and agrees not to plead or
                 claim the same;

         (iii)   agrees that service of process in any such action or
                 proceeding may be effected by  mailing a copy thereof by
                 registered or certified mail (or any substantially similar
                 form and mail), postage prepaid, to each party hereto at its
                 address set forth in Section 7.02 hereof, or at such other
                 address of which the Liquidity Provider shall have been
                 notified pursuant thereto; and

         (iv)    agrees that nothing herein shall affect the right to effect
                 service of process in any other manner permitted by law or
                 shall limit the right to sue in any other jurisdiction.

                 (b)      THE BORROWER AND THE LIQUIDITY PROVIDER EACH HEREBY
AGREE TO WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF
ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM
RELATING TO THE SUBJECT MATTER OF THIS AGREEMENT AND THE RELATIONSHIP THAT IS
BEING ESTABLISHED, including, without limitation, contract claims, tort claims,
breach of duty claims and all other common law and statutory claims.  The
Borrower and the Liquidity Provider each warrant and represent that it has
reviewed this waiver with its legal counsel, and that it knowingly and
voluntarily waives its jury trial rights following consultation with
<PAGE>   33
                                       29

such legal counsel.  THIS WAIVER IS IRREVOCABLE, AND CANNOT BE MODIFIED EITHER
ORALLY OR IN WRITING, AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS,
RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT.

                 (c)      The Liquidity Provider hereby waives any immunity it
may have from the jurisdiction of the courts of the United States or of any
State and waives any immunity any of its properties located in the United
States may have from attachment or execution upon a judgement entered by any
such court under the United States Foreign Sovereign Immunities Act of 1976 or
any similar successor legislation.

                 Section 7.12.  Execution in Counterparts.  This Agreement may
be executed in any number of counterparts and by different parties hereto on
separate counterparts, each of which counterparts, when so executed and
delivered, shall be deemed to be an original and all of which counterparts,
taken together, shall constitute but one and the same Agreement.

                 Section 7.13.  Entirety.  This Agreement, the Intercreditor
Agreement and the other Operative Agreements to which the Liquidity Provider is
a party constitute the entire agreement of the parties hereto with respect to
the subject matter hereof and supersedes all prior understandings and
agreements of such parties.

                 Section 7.14.  Headings.  Section headings in this Agreement
are included herein for convenience of reference only and shall not constitute
a part of this Agreement for any other purpose.

                 Section 7.15.  Transfer.  The Liquidity Provider hereby

Assumption Agreement.

                                   ARTICLE II

                       AMOUNT AND TERMS OF THE COMMITMENT

                 Section 2.01.  The Advances.  The Liquidity Provider hereby
irrevocably agrees, on the terms and conditions hereinafter set forth, to make
Advances to the Borrower from time to time on any Business Day during the
period from the Effective Date until 12:00 Noon (New York City time) on the
Expiry Date (unless the obligations of the Liquidity Provider shall be earlier
terminated in accordance with the terms of Section 2.04(b)) in an aggregate
amount at any time outstanding not to exceed the Maximum Commitment.

                 Section 2.02.  Making the Advances.  (a)  Interest Advances
shall be made in one or more Borrowings by delivery to the Liquidity Provider
of one or more written and completed Notices of Borrowing in substantially the
form of Annex I attached hereto, signed by a Responsible Officer of the
Borrower, in an amount not exceeding the Maximum Commitment at such time and
shall be used solely for the payment when due of the  interest on the Class B
Certificates at the Stated Interest Rate therefor in accordance with Section
3.6(a) of the Intercreditor Agreement.  Each Interest Advance made hereunder
shall automatically reduce the Maximum Commitment and the amount available to
be borrowed hereunder by subsequent Advances by the amount of such Interest
Advance (subject to reinstatement as provided in the next  sentence).  Upon
repayment to the Liquidity Provider in full of the amount of any Interest
Advance made pursuant to this Section 2.02(a), together with accrued interest
thereon (as provided herein), the Maximum Commitment shall be reinstated by the
amount of such repaid Interest Advance; provided, however, that the





<PAGE>   13
                                       9

Maximum Commitment shall not be so reinstated at any time if (i) a Liquidity
Event of Default shall have occurred and be continuing and (ii) there is a
Performing Note Deficiency.

                 (b)      [Intentionally omitted]

                 (c)      A Downgrade Advance shall be made in a single
Borrowing, as provided for in Section 3.6(c) of the Intercreditor Agreement,
(i) upon a downgrading of the Guarantor's short-term unsecured debt rating
issued by any Rating Agency below the applicable Threshold Rating or (ii) if
the Guarantee Agreement ceases to be in full force and effect, becomes invalid
or unenforceable or the Guarantor denies its liability thereunder (any such
occurrence, a "Guarantee Event"), unless a Replacement Liquidity Facility to
replace this Agreement shall have been previously delivered to the Borrower in
accordance with said Section 3.6(c), by delivery to the Liquidity Provider of a
written and completed Notice of Borrowing in substantially the form of Annex
III attached hereto, signed by a Responsible Officer of the Borrower, in an
amount equal to the Maximum Commitment at such time, and shall be used to fund
the Class B Cash Collateral Account in accordance with said Section 3.6(c) and
Section 3.6(f) of the Intercreditor Agreement.

                 (d)      A Final Advance shall be made in a single Borrowing
upon the receipt by the Borrower of a Termination Notice from the Liquidity
Provider pursuant to Section 6.01 hereof by delivery to the Liquidity Provider
of a written and completed Notice of Borrowing in substantially the form of
Annex IV attached hereto, signed by a Responsible Officer of the Borrower, in
an amount equal to the Maximum Commitment at such time, and shall be used to
fund the Class B Cash Collateral Account (in accordance with Section 3.6(i) of
the Intercreditor Agreement) and Section 3.6(f) of the Intercreditor Agreement.

                 (e)      Each Borrowing shall be made on notice in writing (a
"Notice of Borrowing") in substantially the form required by Section 2.02(a),
2.02(c) or 2.02(d), as the case may be, given by the Borrower to the Liquidity
Provider.  If a Notice of Borrowing is delivered by the Borrower in respect of
any Borrowing no later than 12:00 Noon (New York City time) on a Business Day,
upon satisfaction of the conditions precedent set forth in Section 4.02 with
respect to a requested Borrowing, the Liquidity Provider shall make available
to the Borrower, in accordance with its payment instructions, the amount of
such Borrowing in U.S. dollars and immediately available funds, before 12:00
Noon (New York City time) on the first Business Day next following the day of
receipt of such Notice of Borrowing or on such later Business Day specified in
such Notice of Borrowing.  If a Notice of Borrowing is delivered by the
Borrower in respect of any Borrowing after 12:00 Noon (New York City time) on a
Business Day, upon satisfaction of the conditions precedent set forth in
Section 4.02 with respect to a requested Borrowing, the Liquidity Provider
shall make available to the Borrower, in accordance with its payment
instructions, the amount of such Borrowing in U.S. dollars and immediately
available funds, before 12:00 Noon (New York City time) on the second Business
Day next following the day of receipt of such Notice





<PAGE>   14
                                       10

of Borrowing or on such later Business Day specified by the Borrower in such
Notice of Borrowing.  Payments of proceeds of a Borrowing shall be made by wire
transfer of immediately available funds to the Borrower in accordance with such
wire transfer instructions as the Borrower shall furnish from time to time to
the Liquidity Provider for such purpose.  Each Notice of Borrowing shall be
irrevocable and binding on the Borrower.

                 (f)      Upon the making of any Advance requested pursuant to
a Notice of Borrowing, in accordance with the Borrower's payment instructions,
the Liquidity Provider shall be fully discharged of its obligation hereunder
with respect to such Notice of Borrowing, and the Liquidity Provider shall not
thereafter be obligated to make any further Advances hereunder in respect of
such Notice of Borrowing to the Borrower or to any other Person.  Following the
making of any Advance pursuant to Section 2.02(c) or (d) hereof to fund the
Class B Cash Collateral Account, the Liquidity Provider shall have no interest
in or rights to the Class B Cash Collateral Account, such Advance or any other
amounts from time to time on deposit in the Class B Cash Collateral Account;
provided that the foregoing shall not affect or impair the obligations of the
Subordination Agent to make the distributions contemplated by Section 3.6(e) or
(f) of the Intercreditor Agreement.  By paying to the Borrower proceeds of
Advances requested by the Borrower in accordance with the provisions of this
Agreement, the Liquidity Provider makes no representation as to, and assumes no
responsibility for, the correctness or sufficiency for any purpose of the
amount of the Advances so made and requested.

                 Section 2.03.  Fees.  The Borrower agrees to pay to the
Liquidity Provider the fees set forth in the MSCS Fee Letter.

                 Section 2.04.  Reduction or Termination of the Maximum
Commitment.  (a)  Automatic Reduction.  Promptly following each date on which
the Required Amount is reduced as a result of a reduction in the Pool Balance
of the Class B Certificates or otherwise, the Maximum Commitment shall
automatically be reduced to an amount equal to such reduced Required Amount (as
calculated by the Borrower).  The Borrower shall give notice of any such
automatic reduction of the Maximum Commitment to the Liquidity Provider within
two Business Days thereof.  The failure by the Borrower to furnish any such
notice shall not affect such automatic reduction of the Maximum Commitment.

                 (b)      Termination.  Upon the making of any Provider Advance
or Final Advance hereunder or the occurrence of the Termination Date, the
obligation of the Liquidity Provider to make further Advances hereunder shall
automatically and irrevocably terminate, and the Borrower shall not be entitled
to request any further Borrowing hereunder.

                 Section 2.05.  Repayments of Interest Advances or the Final
Advance.  Subject to Sections 2.06, 2.07 and 2.09 hereof, the Borrower hereby
agrees, without notice of an Advance or demand for repayment from the Liquidity
Provider (which notice and





<PAGE>   15
                                       11

demand are hereby waived by the Borrower), to pay, or to cause to be paid, to
the Liquidity Provider on each date on which the Liquidity Provider shall make
an Interest Advance or the Final Advance, an amount equal to (a) the amount of
such Advance (any such Advance, until repaid, is referred to herein as an
"Unpaid Advance"), plus (b) interest on the amount of each such Unpaid Advance
as provided in Section 3.07 hereof; provided that if (i) the Liquidity Provider
shall make a Provider Advance at any time after making one or more Interest
Advances which shall not have been repaid in accordance with this Section 2.05
or (ii) this Liquidity Facility shall become a Downgraded Facility at any time
when unreimbursed Interest Advances have reduced the Maximum Commitment to
zero, then such Interest Advances shall cease to constitute Unpaid Advances and
shall be deemed to have been changed into an Applied Downgrade Advance for all
purposes of this Agreement (including, without limitation, for the purpose of
determining when such Interest Advance is required to be repaid to the
Liquidity Provider in accordance with Section 2.06 and for the purposes of
Section 2.06(b)). The Borrower and the Liquidity Provider agree that the
repayment in full of each Interest Advance and Final Advance on the date such
Advance is made is intended to be a contemporaneous exchange for new value
given to the Borrower by the Liquidity Provider.

                 Section 2.06.  Repayments of Provider Advances.  (a)  Amounts
advanced hereunder in respect of a Provider Advance shall be deposited in the
Class B Cash Collateral Account, invested and withdrawn from the Class B Cash
Collateral Account as set forth in Sections 3.6(c), (d) and (f) of the
Intercreditor Agreement.  The Borrower agrees to pay to the Liquidity Provider,
on each Regular Distribution Date, commencing on the first Regular Distribution
Date after the making of a Provider Advance, interest on the principal amount
of any such Provider Advance as provided in Section 3.07; provided, however,
that amounts in respect of a Provider Advance withdrawn from the Class B Cash
Collateral Account for the purpose of paying interest on the Class B
Certificates in accordance with Section 3.6(f) of the Intercreditor Agreement
(the amount of any such withdrawal being an "Applied Provider Advance") shall
thereafter (subject to Section 2.06(b)) be treated as an Interest Advance under
this Agreement for purposes of determining the Applicable Liquidity Rate for
interest payable thereon; provided further, however, that if, following the
making of a Provider Advance, the Liquidity Provider delivers a Termination
Notice to the Borrower pursuant to Section 6.01 hereof, such Provider Advance
shall thereafter be treated as a Final Advance under this Agreement for
purposes of determining the Applicable Liquidity Rate for interest payable
thereon.  Subject to Sections 2.07 and 2.09 hereof, immediately upon the
withdrawal of any amounts from the Class B Cash Collateral Account on account
of a reduction in the Required Amount, the Borrower shall repay to the
Liquidity Provider a portion of the Provider Advances in a principal amount
equal to such reduction, plus interest on the principal amount prepaid as
provided in Section 3.07 hereof.

                 (b)      At any time when an Applied Provider Advance (or any
portion thereof) is outstanding, upon the deposit in the Class B Cash

amount pursuant to clause "third" of Section 2.4(b) of the Intercreditor
Agreement, clause "third" of Section 3.2 of the Intercreditor Agreement or
clause "fourth" of Section 3.3 of the Intercreditor Agreement (any such amount
being a "Replenishment Amount") for the purpose of replenishing or increasing
the balance thereof up to the Required Amount at such time, (i) the aggregate
outstanding principal amount of all Applied Provider Advances (and of Provider
Advances treated as an Interest Advance for purposes of determining the
Applicable Liquidity Rate for interest payable thereon) shall be automatically
reduced by the amount of such Replenishment Amount and (ii) the aggregate
outstanding principal amount of all Unapplied Provider Advances shall be
automatically increased by the amount of such Replenishment Amount.

                 (c)      Upon the provision of a Replacement Liquidity
Facility in replacement of this Agreement in accordance with Section 3.6(e) of
the Intercreditor Agreement, amounts remaining on deposit in the Class B Cash
Collateral Account after giving effect to any Applied Provider Advance on the
date of such replacement shall be reimbursed to the Liquidity Provider, but
only to the extent such amounts are necessary to repay in full to the Liquidity
Provider all amounts owing to it hereunder.

                 Section 2.07.  Payments to the Liquidity Provider Under the
Intercreditor Agreement.  In order to provide for payment or repayment to the
Liquidity Provider of any amounts hereunder, the Intercreditor Agreement
provides that amounts available and referred to in Articles II and III of the
Intercreditor Agreement, to the extent payable to the Liquidity Provider
pursuant to the terms of the Intercreditor Agreement (including, without
limitation, Section 3.6(f) of the Intercreditor Agreement), shall be paid to
the Liquidity Provider in accordance with the terms thereof.  Amounts so paid
to the Liquidity Provider shall be applied by the Liquidity Provider to
Liquidity Obligations then due and payable in accordance with the Intercreditor
Agreement or, if not provided for in the Intercreditor Agreement, then in such
manner as the Liquidity Provider shall deem appropriate.

                 Section 2.08.  Book Entries.  The Liquidity Provider shall
maintain in accordance with its usual practice an account or accounts
evidencing the indebtedness of the Borrower resulting from Advances made from
time to time and the amounts of principal and interest payable hereunder and
paid from time to time in respect thereof; provided, however, that the failure
by the Liquidity Provider to maintain such account or accounts shall not affect
the obligations of the Borrower in respect of Advances.

                 Section 2.09.  Payments from Available Funds Only.  All
payments to be made by the Borrower under this Agreement shall be made only
from the amounts that constitute Scheduled Payments, Special Payments or
payments under Section 8.1 or 9.1, as the case may be, of the Participation
Agreements and Section 6 of the Note Purchase Agreement and only to the extent
that the Borrower shall have sufficient income or proceeds therefrom to enable
the Borrower to make payments in accordance with the terms hereof





<PAGE>   17
                                       13

after giving effect to the priority of payments provisions set forth in the
Intercreditor Agreement.  The Liquidity Provider agrees that it will look
solely to such amounts to the extent available for distribution to it as
provided in the Intercreditor Agreement and this Agreement and that the
Borrower, in its individual capacity, is not personally liable to it for any
amounts payable or liability under this Agreement except as expressly provided
in this Agreement, the Intercreditor Agreement or any Participation Agreement.
Amounts on deposit in the Class B Cash Collateral Account shall be available to
the Borrower to make payments under this Agreement only to the extent and for
the purposes expressly contemplated in Section 3.6(f) of the Intercreditor
Agreement.

                 Section 2.10.  [Intentionally omitted]

                                  ARTICLE III

                          OBLIGATIONS OF THE BORROWER

                 Section 3.01.  Increased Costs.  The Borrower shall pay to the
Liquidity Provider from time to time such amounts as may be necessary to
compensate the Liquidity Provider for any increased costs incurred by the
Liquidity Provider which are attributable to its making or maintaining any
LIBOR Advances hereunder or its obligation to make any such Advances hereunder,
or any reduction in any amount receivable by the Liquidity Provider under this
Agreement or the Intercreditor Agreement in respect of any such Advances or
such obligation (such increases in costs and reductions in amounts receivable
being herein called "Additional Costs"), resulting from any change after the
date of this Agreement in U.S. federal, state, municipal, or foreign laws or
regulations which changes the basis of taxation of any amounts payable to the
Liquidity Provider under this Agreement in respect of any such Advances (other
than Excluded Taxes).  The Liquidity Provider agrees to use reasonable efforts
(consistent with applicable legal and regulatory restrictions) to change the
jurisdiction of its Lending Office if making such change would avoid the need
for, or reduce the amount of, any amount payable under this Section that may
thereafter accrue and would not, in the reasonable judgment of the Liquidity
Provider, be otherwise disadvantageous to the Liquidity Provider.

                 The Liquidity Provider will notify the Borrower of any event
occurring after the date of this Agreement that will entitle the Liquidity
Provider to compensation pursuant to this Section 3.01 as promptly as
practicable after it obtains knowledge thereof and determines to request such
compensation, which notice shall describe in reasonable detail the calculation
of the amounts owed under this Section.  Determinations by the Liquidity
Provider for purposes of this Section 3.01 of the effect of any Regulatory
Change on its costs of making or maintaining Advances or on amounts receivable
by it in respect of Advances, and of the additional amounts required to
compensate the Liquidity Provider in respect of any Additional Costs, shall be
prima facie evidence of the amount owed under this Section.

                                       14


                 Section 3.02.  Capital Adequacy.  If (1) the adoption, after
the date hereof, of any applicable governmental law, rule or regulation
regarding capital adequacy, (2) any change, after the date hereof, in the
interpretation or administration of any such law, rule or regulation by any
central bank or other governmental authority charged with the interpretation or
administration thereof or (3) compliance by the Liquidity Provider or any
corporation controlling the Liquidity Provider with any applicable guideline or
request of general applicability, issued after the date hereof, by any central
bank or other governmental authority (whether or not having the force of law)
that constitutes a change of the nature described in clause (2), has the effect
of requiring an increase in the amount of capital required to be maintained by
the Liquidity Provider or any corporation controlling the Liquidity Provider,
and such increase is based upon the Liquidity Provider's obligations hereunder
and other similar obligations, the Borrower shall pay to the Liquidity Provider
from time to time such additional amount or amounts as are necessary to
compensate the Liquidity Provider for such portion of such increase as shall be
reasonably allocable to the Liquidity Provider's obligations to the Borrower
hereunder.  The Liquidity Provider agrees to use reasonable efforts (consistent
with applicable legal and regulatory restrictions) to change the jurisdiction
of its Lending Office if making such change would avoid the need for, or reduce
the amount of, any amount payable under this Section that may thereafter accrue
and would not, in the reasonable judgment of the Liquidity Provider, be
otherwise materially disadvantageous to the Liquidity Provider.

                 The Liquidity Provider will notify the Borrower of any event
occurring after the date of this Agreement that will entitle the Liquidity
Provider to compensation pursuant to this Section 3.02 as promptly as
practicable after it obtains knowledge thereof and determines to request such
compensation, which notice shall describe in reasonable detail the calculation
of the amounts owed under this Section.  Determinations by the Liquidity
Provider for purposes of this Section 3.02 of the effect of any increase in the
amount of capital required to be maintained by the bank and of the amount
allocable to the Liquidity Provider's obligations to the Borrower hereunder
shall be prima facie evidence of the amounts owed under this Section.

                 Section 3.03.  Payments Free of Deductions.  All payments made
by the Borrower under this Agreement shall be made free and clear of, and
without reduction for or on account of, any present or future stamp or other
taxes, levies, imposts, duties, charges, fees, deductions, withholdings,
restrictions or conditions of any nature whatsoever now or hereafter imposed,
levied, collected, withheld or assessed, excluding Excluded Taxes (such
non-excluded taxes being referred to herein, collectively, as "Non-Excluded
Taxes" and, individually, as a "Non-Excluded Tax").  If any Non-Excluded Taxes
are required to be withheld from any amounts payable to the Liquidity Provider
under this Agreement, the amounts so payable to the Liquidity Provider shall be
increased to the extent necessary to yield to the Liquidity Provider (after
payment of all Non-Excluded Taxes) interest or any other such amounts payable
under this Agreement at the rates or in the amounts specified in





<PAGE>   19
                                       15

this Agreement.  The Liquidity Provider agrees to use reasonable efforts
(consistent with its internal policy and legal and regulatory restrictions) to
change the jurisdiction of its Lending Office if making such change would avoid
the need for, or reduce the amount of, any such additional amounts that may
thereafter accrue and would not, in the reasonable judgment of the Liquidity
Provider, be otherwise disadvantageous to the Liquidity Provider.  From time to
time upon the reasonable request of the Borrower, the Liquidity Provider agrees
to provide to the Borrower two original Internal Revenue Service Forms 1001 or
4224, as appropriate, or any successor or other form prescribed by the Internal
Revenue Service, certifying that the Liquidity Provider is exempt from or
entitled to a reduced rate of United States withholding tax on payments
pursuant to this Agreement.

                 (b)      All payments (including, without limitation,
Advances) made by the Liquidity Provider under this Agreement shall be made
free and clear of, and without reduction for or on account of, any Taxes.  If
any Taxes are required to be withheld or deducted from any amounts payable to
the Borrower under this Agreement, the Liquidity Provider shall (i) within the
time prescribed therefor by applicable law pay to the appropriate governmental
or taxing authority the full amount of any such Taxes (and any additional Taxes
in respect of the payment required under clause (ii) hereof) and make such
reports or returns in connection therewith at the time or times and in the
manner prescribed by applicable law, and (ii) pay to the Borrower an additional
amount which (after deduction of all such Taxes) will be sufficient to yield to
the Borrower the full amount which would have been received by it had no such
withholding or deduction been made.  Within 30 days after the date of each
payment hereunder, the Liquidity Provider shall furnish to the Borrower the
original or a certified copy of (or other documentary evidence of) the payment
of the Taxes applicable to such payment.

                 Section 3.04.  Payments.  The Borrower shall make or cause to
be made each payment to the Liquidity Provider under this Agreement so as to
cause the same to be received by the Liquidity Provider not later than 1:00
P.M.  (New York City time) on the day when due.  The Borrower shall make all
such payments in lawful money of the United States of America, to the Liquidity
Provider in immediately available funds, by wire transfer to Citibank, N.A.,
New York, NY, ABA# 021000089, Account Name: Morgan Stanley Capital Services,
Inc., Account # 4072-4601, Reference: Atlas Air, Inc., 1998-1B.

                 Section 3.05.  Computations.  All computations of interest
based on the Base Rate shall be made on the basis of a year of 365 or 366 days,
as the case may be, and all computations of interest based on the LIBOR Rate
shall be made on the basis of a year of 360 days, in each case for the actual
number of days (including the first day but excluding the last day) occurring
in the period for which such interest is payable.

                 Section 3.06.  Payment on Non-Business Days.  Whenever any
payment to be made hereunder shall be stated to be due on a day other than a
Business Day, such payment





<PAGE>   20
                                       16

shall be made on the next succeeding Business Day and no additional interest
shall be due as a result (and if so made, shall be deemed to have been made
when due).  If any payment in respect of interest on an Advance is so deferred
to the next succeeding Business Day, such deferral shall not delay the
commencement of the next Interest Period for such Advance (if such Advance is a
LIBOR Advance) or reduce the number of days for which interest will be payable
on such Advance on the next interest payment date for such Advance.

                 Section 3.07.  Interest.  (a)  Subject to Section 2.09, the
Borrower shall pay, or shall cause to be paid, without duplication, interest on
(i) the unpaid principal amount of each Advance from and including the date of
such Advance (or, in the case of an Applied Provider Advance, from and
including the date on which the amount thereof was withdrawn from the Class B
Cash Collateral Account to pay interest on the Class B Certificates) to but
excluding the date such principal amount shall be paid in full (or, in the case
of an Applied Provider Advance, the date on which the Class B Cash Collateral
Account is fully replenished in respect of such Advance) and (ii) any other
amount due hereunder (whether fees, commissions, expenses or other amounts or,
to the extent permitted by law, installments of interest on Advances or any
such other amount) which is not paid when due (whether at stated maturity, by
acceleration or otherwise) from and including the due date thereof to but
excluding the date such amount is paid in full, in each such case, at a
fluctuating interest rate per annum for each day equal to the Applicable
Liquidity Rate (as defined below) for such Advance or such other amount as in
effect for such day, but in no event at a rate per annum greater than the
maximum rate permitted by applicable law; provided, however, that, if at any
time the otherwise applicable interest rate as set forth in this Section 3.07
shall exceed the maximum rate permitted by applicable law, then any subsequent
reduction in such interest rate will not reduce the rate of interest payable
pursuant to this Section 3.07 below the maximum rate permitted by applicable
law until the total amount of interest accrued equals the amount of interest
that would have accrued if such otherwise applicable interest rate as set forth
in this Section 3.07 had at all times been in effect.

                 (b)      Except as provided in clause (e) below, each Advance
will be either a Base Rate Advance or a LIBOR Advance as provided in this
Section.  Each such Advance will be a Base Rate Advance for the period from the
date of its borrowing to (but excluding) the third Business Day following the
Liquidity Provider's receipt of the Notice of Borrowing for such Advance.
Thereafter, such Advance shall be a LIBOR Advance; provided that the Borrower
(at the direction of the Controlling Party), so long as the Liquidity Provider
is not the Controlling Party) may (x) convert the Final Advance into a Base
Rate Advance on the last day of an Interest Period for such Advance by giving
the Liquidity Provider no less than four Business Days' prior written notice of
such election or (y) elect to maintain the Final Advance as a Base Rate Advance
by not requesting a conversion of the Final Advance to a LIBOR Advance under
Clause (5) of the applicable Notice of Borrowing.





<PAGE>   21
                                       17

                 (c)      Each LIBOR Advance shall bear interest during each
Interest Period at a rate per annum equal to the LIBOR Rate for such Interest
Period plus the Applicable Margin for such LIBOR Advance, payable in arrears on
the last day of such Interest Period and, in the event of the payment of
principal of such LIBOR Advance on a day other than such last day, on the date
of such payment (to the extent of interest accrued on the amount of principal
repaid).

                 (d)      Each Base Rate Advance shall bear interest at a rate
per annum equal to the Base Rate plus the Applicable Margin for such Base Rate
Advance, payable in arrears on each Regular Distribution Date and, in the event
of the payment of principal of such Base Rate Advance on a day other than a
Regular Distribution Date, on the date of such payment (to the extent of
interest accrued on the amount of principal repaid).

                 (e)      Each Unapplied Downgrade Advance (i) during the
period from and including the date of the making of such Unapplied Downgrade
Advance through but excluding the Expiry Date (or, if earlier, the date of
repayment thereof or of conversion thereof into a Final Advance), shall bear
interest at a rate per annum equal to the LIBOR Rate for such Interest Period
plus 0.40% on the amount of such Unapplied Downgrade Advance from time to time
during such period, payable in arrears on each Regular Distribution Date and
(ii) thereafter, shall be a LIBOR Advance and shall bear interest in accordance
with clause (c) above.

                 (f)      [Intentionally omitted]

                 (g)      Each amount not paid when due hereunder (whether
fees, commissions, expenses or other amounts or, to the extent permitted by
applicable law, installments of interest on Advances but excluding Advances)
shall bear interest at a rate per annum equal to the Base Rate plus 2.00% until
paid.

                 (h)      Each change in the Base Rate shall become effective
immediately.  The rates of interest specified in this Section 3.07 with respect
to any Advance or other amount shall be referred to as the "Applicable
Liquidity Rate".

                 Section 3.08.  Replacement of Borrower.  From time to time and
subject to the successor Borrower's meeting the eligibility requirements set
forth in Section 6.9 of the Intercreditor Agreement applicable to the
Subordination Agent, upon the effective date and time specified in a written
and completed Notice of Replacement Subordination Agent in substantially the
form of Annex V attached hereto (a "Notice of Replacement Subordination Agent")
delivered to the Liquidity Provider by the then Borrower, the successor
Borrower designated therein shall be substituted for as the Borrower for all
purposes hereunder.

                 Section 3.09.  Funding Loss Indemnification.  The Borrower
shall pay to the Liquidity Provider, upon the request of the Liquidity
Provider, such amount or amounts as shall be sufficient (in the reasonable
opinion of the Liquidity Provider) to compensate it for any loss, cost, or
expense incurred by reason of the liquidation or redeployment of deposits or
other funds acquired by the Liquidity Provider to fund or maintain any LIBOR
Advance (but excluding loss of anticipated profits) incurred as a result of:

                 (1)      Any repayment of a LIBOR Advance on a date other than
         the last day of the Interest Period for such Advance; or

                 (2)      Any failure by the Borrower to borrow a LIBOR Advance
         on the date for borrowing specified in the relevant notice under
         Section 2.02.

                 Section 3.10.  Illegality.  Notwithstanding any other
provision in this Agreement, if any change in any applicable law, rule or
regulation, or any change in the interpretation or administration thereof by
any governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by the Liquidity
Provider (or its Lending Office) with any request or directive (whether or not
having the force of law) of any such authority, central bank or comparable
agency shall make it unlawful or impossible for the Liquidity Provider (or its
Lending Office) to maintain or fund its LIBOR Advances, then upon notice to the
Borrower by the Liquidity Provider, the outstanding principal amount of the
LIBOR Advances shall be converted to Base Rate Advances (a) immediately upon
demand of the Liquidity Provider, if such change or compliance with such
request, in the judgment of the Liquidity Provider, requires immediate
repayment; or (b) at the expiration of the last Interest Period to expire
before the effective date of any such change or request.

         reasonably requested.

                 (b)      The following statement shall be true on and as of

from the entering into of this Agreement or the making of any Advance, which
constitutes a Liquidity Event of Default.

                 (c)      The Liquidity Provider shall have received payment in

                                       21


                  (a)     Performance of This and Other Agreements.  Punctually
         pay or cause to be paid all amounts payable by it under this Agreement
         and the other Operative Agreements and observe and perform in all
         material respects the conditions, covenants and requirements
         applicable to it contained in this Agreement and the other Operative
         Agreements.

                 (b)      Reporting Requirements.  Furnish to the Liquidity
         Provider with reasonable promptness, such other information and data
         with respect to the transactions contemplated by the Operative
         Agreements as from time to time may be reasonably requested by the
         Liquidity Provider; and permit the Liquidity Provider, upon reasonable

to either party shall in addition be delivered to each of the parties to the
Participation Agreements at their respective addresses set forth therein.

                 Section 7.03. No Waiver: Remedies.  No failure on the part of
the Liquidity Provider to exercise, and no delay in exercising, any right under
this Agreement shall operate as a waiver thereof; nor shall any single or

herein provided are cumulative and not exclusive of any remedies provided by
law.

                 Section 7.04.  Further Assurances.  The Borrower agrees to do
such further acts and things and to execute and deliver to the Liquidity
Provider such additional assignments, agreements, powers and instruments as the

described in Sections 3.01, 3.02 or 7.07 hereof or in the MSCS Fee Letter
(regardless of whether indemnified against pursuant to said Sections or in such
MSCS Fee Letter)), that may be imposed, incurred by or asserted against any
Liquidity Indemnitee, in any way relating to, resulting from, or arising out of
or in connection with any action, suit or proceeding by any third party against
such Liquidity Indemnitee and relating to this Agreement, the MSCS Fee Letter,
the Intercreditor Agreement or any Financing Agreement; provided, however, that
the Borrower shall not be required to indemnify, protect, defend and hold
harmless any Liquidity Indemnitee in respect of any Expense of such Liquidity
Indemnitee (i) to the extent such Expense is attributable to the gross
negligence or willful misconduct of such Liquidity Indemnitee or any other
Liquidity Indemnitee, (ii) ordinary and usual operating overhead expense, or
(iii) attributable to the failure by such Liquidity Indemnitee or any other
Liquidity Indemnitee to perform or observe any agreement, covenant or condition
on its part to be performed or observed in this Agreement, the Intercreditor
Agreement, the MSCS Fee Letter or any other Operative Agreement to which it is

                 Section 7.06.  Liability of the Liquidity Provider.  (a)
Neither the Liquidity Provider nor any of its officers, employees, directors or
affiliates shall be liable or responsible for: (i) the use which may be made of
the Advances or any acts or omissions of the Borrower or any beneficiary or
transferee in connection therewith; (ii) the validity, sufficiency or
genuineness of documents, or of any endorsement thereon, even if such documents
should prove to be in any or all respects invalid, insufficient, fraudulent or
forged; or (iii) the making of Advances by the Liquidity Provider against
delivery of a Notice of Borrowing and other documents which do not comply with
the terms hereof; provided, however, that the Borrower shall have a claim
against the Liquidity Provider, and the Liquidity Provider shall be liable to
the Borrower, to the extent of any damages suffered by the Borrower which were
the result of (A) the Liquidity Provider's willful misconduct or negligence in
determining whether documents presented hereunder comply with the terms hereof,
or (B) any breach by the Liquidity Provider of any of the terms of this
Agreement, including, but not limited to, the Liquidity Provider's failure to
make lawful payment hereunder after the delivery to it by the Borrower of a
Notice of Borrowing strictly complying with the terms and conditions hereof.

                 (b)      Neither the Liquidity Provider nor any of its
officers, employees, director or affiliates shall be liable or responsible in
any respect for (i) any error, omission, interruption or delay in transmission,
dispatch or delivery of any message or advice, however transmitted, in
connection with this Agreement or any Notice of Borrowing delivered hereunder,
or (ii) any action, inaction or omission which may be taken by it in good
faith, absent willful misconduct or negligence (in which event the extent of
the Liquidity Provider's potential liability to the Borrower shall be limited
as set forth in the immediately preceding paragraph), in connection with this
Agreement or any Notice of Borrowing.

                 Section 7.07.  Costs, Expenses and Taxes.  The Borrower agrees
to pay, or cause to be paid (A) on the Effective Date and on such later date or
dates on which the Liquidity Provider shall make demand, all reasonable out-of-
pocket costs and expenses (including, without limitation, the reasonable fees
and expenses of outside counsel for the Liquidity Provider) of the Liquidity
Provider in connection with the preparation, negotiation, execution, delivery,
filing and recording of this Agreement, any other Operative Agreement and any
other documents which may be delivered in connection with this Agreement and
(B) on demand, all reasonable costs and expenses (including reasonable counsel
fees and expenses) of the Liquidity Provider in connection with (i) the
enforcement of this Agreement or any other Operative Agreement, (ii) the
modification or amendment of, or supplement to, this Agreement or any other
Operative Agreement or such other documents which may be delivered in
connection herewith or therewith (whether or not the same shall become
effective) or (iii) any action or proceeding relating to any order, injunction,
or other process or decree restraining or seeking to restrain the Liquidity
Provider from paying any amount under this Agreement, the Intercreditor
Agreement or any other Operative Agreement or otherwise affecting the
application of funds in the Class B Cash Collateral Account.  In





<PAGE>   29
                                       25

addition, the Borrower shall pay any and all recording, stamp and other similar
taxes and fees payable or determined to be payable in connection with the
execution, delivery, filing and recording of this Agreement, any other
Operative Agreement and such other documents, and agrees to save the Liquidity
Provider harmless from and against any and all liabilities with respect to or
resulting from any delay in paying or omission to pay such taxes or fees.

                 Section 7.08.  Binding Effect; Participations.

                 (a)      This Agreement shall be binding upon and inure to the
benefit of the Borrower and the Liquidity Provider and their respective
successors and assigns, except that neither the Liquidity Provider (except as
otherwise provided in this Section 7.08) nor (except as contemplated by Section
3.08) the Borrower shall have the right to assign its rights or obligations
hereunder or any interest herein without the prior written consent of the other
party, subject to the requirements of Section 7.08(b). The Liquidity Provider
may grant participations herein or in any of its rights hereunder (including,
without limitation, funded participations and participations in rights to
receive interest payments hereunder) and under the other Operative Agreements
to such Persons as the Liquidity Provider may in its sole discretion select,
subject to the requirements of Section 7.08(b). No such participation by the
Liquidity Provider, however, will relieve the Liquidity Provider of its
obligations hereunder.  In connection with any participation or any proposed
participation, the Liquidity Provider may disclose to the participant or the
proposed participant any information that the Borrower is required to deliver
or to disclose to the Liquidity Provider pursuant to this Agreement.  The
Borrower acknowledges and agrees that the Liquidity Provider's source of funds
may derive in part from its participants (other than Atlas).  Accordingly,
references in this Agreement and the other Operative Agreements to
determinations, reserve and capital adequacy requirements, increased costs,
reduced receipts, additional amounts due pursuant to Section 3.03(a) and the
like as they pertain to the Liquidity Provider shall be deemed also to include
those of each of its participants (subject, in each case, to the maximum amount
that would have been incurred by or attributable to the Liquidity Provider
directly if the Liquidity Provider, rather than the participant, had held the
interest participated).

                 (b)      If, pursuant to subsection (a) above, the Liquidity
Provider sells any participation in this Agreement to any bank or other entity
(each, a "Transferee"), then, concurrently with the effectiveness of such
participation, the Transferee shall (i) represent to the Liquidity Provider
(for the benefit of the Liquidity Provider and the Borrower) either (A) that it
is incorporated under the laws of the United States or a state thereof or (B)
that under applicable law and treaties, no taxes will be required to be
withheld with respect to any payments to be made to such Transferee in respect
of this Agreement, (ii) furnish to the Liquidity Provider and the Borrower
either (x) a statement that it is incorporated under the laws of the United
States or a state thereof or (y) if it is not so incorporated, two copies of a
properly completed United States Internal Revenue Service Form 4224 or Form
1001, as appropriate, or other applicable form, certificate or document
prescribed by the Internal





<PAGE>   30
                                       26

Revenue Service certifying, in each case, such Transferee's entitlement to a
complete exemption from United States federal withholding tax in respect to any
and all payments to be made hereunder, and (iii) agree (for the benefit of the
Liquidity Provider and the Borrower) to provide the Liquidity Provider and the
Borrower a new Form 4224 or Form 1001, as appropriate, (A) on or before the
date that any such form expires or becomes obsolete or (B) after the occurrence
of any event requiring a change in the most recent form previously delivered by
it and prior to the immediately following due date of any payment by the
Borrower hereunder, certifying in the case of a Form 1001 or Form 4224 that
such Transferee is entitled to a complete exemption from United States federal
withholding tax on payments under this Agreement.  Unless the Borrower has
received forms or other documents reasonably satisfactory to it (and required
by applicable law) indicating that payments hereunder are not subject to United
States federal withholding tax, the Borrower will withhold taxes as required by
law from such payments at the applicable statutory rate.

                 Section 7.09.  Severability.  Any provision of this Agreement
which is prohibited, unenforceable or not authorized in any jurisdiction shall,
as to such jurisdiction, be ineffective to the extent of such prohibition,
unenforceability or nonauthorization without invalidating the remaining
provisions hereof or affecting the validity, enforceability or legality of such
provision in any other jurisdiction.

                 Section 7.10.  GOVERNING LAW.  THIS AGREEMENT SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW
YORK.

                 Section 7.11.  Submission to Jurisdiction; Waiver of Jury
Trial; Waiver of Immunity.  (a)  Each of the parties hereto hereby irrevocably
and unconditionally:

         (i)     submits for itself and its property in any legal action or
                 proceeding relating to this Agreement or any other Operative
                 Agreement, or for recognition and enforcement of any judgment
                 in respect hereof or thereof, to the nonexclusive general
                 jurisdiction of the courts of the State of New York, the
                 courts of the United States of America for the Southern
                 District of New York, and the appellate courts from any
                 thereof;

         (ii)    consents that any such action or proceeding may be brought in

                 hereafter have to the venue of any such action or proceeding
                 in any such court or that such action or  proceeding was
                 brought in an inconvenient court and agrees not to plead or
                 claim the same;

         (iii)   agrees that service of process in any such action or
                 proceeding may be effected by  mailing a copy thereof by
                 registered or certified mail (or any substantially

                 at its address set forth in Section 7.02 hereof, or at such
                 other address of which the Liquidity Provider shall have been
                 notified pursuant thereto; and

         (iv)    agrees that nothing herein shall affect the right to effect
                 service of process in any other manner permitted by law or
                 shall limit the right to sue in any other jurisdiction.

                 (b)      THE BORROWER AND THE LIQUIDITY PROVIDER EACH HEREBY
AGREE TO WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF
ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM
RELATING TO THE SUBJECT MATTER OF THIS AGREEMENT AND THE RELATIONSHIP THAT IS
BEING ESTABLISHED, including, without limitation, contract claims, tort claims,
breach of duty claims and all other common law and statutory claims.  The
Borrower and the Liquidity Provider each warrant and represent that it has
reviewed this waiver with its legal counsel, and that it knowingly and
voluntarily waives its jury trial rights following consultation with such legal
counsel.  THIS WAIVER IS IRREVOCABLE, AND CANNOT BE MODIFIED EITHER ORALLY OR
IN WRITING, AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS,
SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT.

                 Section 7.12.  Execution in Counterparts.  This Agreement may
be executed in any number of counterparts and by different parties hereto on
separate counterparts, each of which counterparts, when so executed and
delivered, shall be deemed to be an original and all of which counterparts,
taken together, shall constitute but one and the same Agreement.

                 Section 7.13.  Entirety.  This Agreement, the Intercreditor
Agreement and the other Operative Agreements to which the Liquidity Provider is
a party constitute the entire agreement of the parties hereto with respect to
the subject matter hereof and supersedes all prior understandings and
agreements of such parties.

                 Section 7.14.  Headings.  Section headings in this Agreement
are included herein for convenience of reference only and shall not constitute
a part of this Agreement for any other purpose.

                 Section 7.15.  Transfer.  The Liquidity Provider hereby
acknowledges and consents to the Transfer contemplated by the Assignment and
Assumption Agreement.

                                   ARTICLE II

                       AMOUNT AND TERMS OF THE COMMITMENT

                 Section 2.01.  The Advances.  The Liquidity Provider hereby
irrevocably agrees, on the terms and conditions hereinafter set forth, to make
Advances to the Borrower from time to time on any Business Day during the
period from the Effective Date until 12:00 Noon (New York City time) on the
Expiry Date (unless the obligations of the Liquidity Provider shall be earlier
terminated in accordance with the terms of Section 2.04(b)) in an aggregate
amount at any time outstanding not to exceed the Maximum Commitment.

                 Section 2.02.  Making the Advances.  (a)  Interest Advances
shall be made in one or more Borrowings by delivery to the Liquidity Provider
of one or more written and completed Notices of Borrowing in substantially the
form of Annex I attached hereto, signed by a Responsible Officer of the
Borrower, in an amount not exceeding the Maximum Commitment at such time and
shall be used solely for the payment when due of the  interest on the Class C
Certificates at the Stated Interest Rate therefor in accordance with Section
3.6(a) of the Intercreditor Agreement.  Each Interest Advance made hereunder
shall automatically reduce the Maximum Commitment and the amount available to
be borrowed hereunder by subsequent Advances by the amount of such Interest
Advance (subject to reinstatement as provided in the next  sentence).  Upon
repayment to the Liquidity Provider in full of the amount of any Interest
Advance made pursuant to this Section 2.02(a), together with accrued interest
thereon (as provided herein), the Maximum Commitment shall be reinstated by the
amount of such repaid Interest Advance; provided, however, that the
<PAGE>   13
                                       9

Maximum Commitment shall not be so reinstated at any time if (i) a Liquidity
Event of Default shall have occurred and be continuing and (ii) there is a
Performing Note Deficiency.

                 (b)      [Intentionally omitted]

                 (c)      A Downgrade Advance shall be made in a single
Borrowing, as provided for in Section 3.6(c) of the Intercreditor Agreement,
(i) upon a downgrading of the Guarantor's short-term unsecured debt rating
issued by any Rating Agency below the applicable Threshold Rating or (ii) if
the Guarantee Agreement ceases to be in full force and effect, becomes invalid
or unenforceable or the Guarantor denies its liability thereunder (any such
occurrence, a "Guarantee Event"), unless a Replacement Liquidity Facility to
replace this Agreement shall have been previously delivered to the Borrower in
accordance with said Section 3.6(c), by delivery to the Liquidity Provider of a
written and completed Notice of Borrowing in substantially the form of Annex
III attached hereto, signed by a Responsible Officer of the Borrower, in an
amount equal to the Maximum Commitment at such time, and shall be used to fund
the Class C Cash Collateral Account in accordance with said Section 3.6(c) and
Section 3.6(f) of the Intercreditor Agreement.

                 (d)      A Final Advance shall be made in a single Borrowing
upon the receipt by the Borrower of a Termination Notice from the Liquidity
Provider pursuant to Section 6.01 hereof by delivery to the Liquidity Provider
of a written and completed Notice of Borrowing in substantially the form of
Annex IV attached hereto, signed by a Responsible Officer of the Borrower, in
an amount equal to the Maximum Commitment at such time, and shall be used to
fund the Class C Cash Collateral Account (in accordance with Section 3.6(i) of
the Intercreditor Agreement) and Section 3.6(f) of the Intercreditor Agreement.

                 (e)      Each Borrowing shall be made on notice in writing (a
"Notice of Borrowing") in substantially the form required by Section 2.02(a),
2.02(c) or 2.02(d), as the case may be, given by the Borrower to the Liquidity
Provider.  If a Notice of Borrowing is delivered by the Borrower in respect of
any Borrowing no later than 12:00 Noon (New York City time) on a Business Day,
upon satisfaction of the conditions precedent set forth in Section 4.02 with
respect to a requested Borrowing, the Liquidity Provider shall make available
to the Borrower, in accordance with its payment instructions, the amount of
such Borrowing in U.S. dollars and immediately available funds, before 12:00
Noon (New York City time) on the first Business Day next following the day of
receipt of such Notice of Borrowing or on such later Business Day specified in
such Notice of Borrowing.  If a Notice of Borrowing is delivered by the
Borrower in respect of any Borrowing after 12:00 Noon (New York City time) on a
Business Day, upon satisfaction of the conditions precedent set forth in
Section 4.02 with respect to a requested Borrowing, the Liquidity Provider
shall make available to the Borrower, in accordance with its payment
instructions, the amount of such Borrowing in U.S. dollars and immediately
available funds, before 12:00 Noon (New York City time) on the second Business
Day next following the day of receipt of such Notice
<PAGE>   14
                                       10

of Borrowing or on such later Business Day specified by the Borrower in such
Notice of Borrowing.  Payments of proceeds of a Borrowing shall be made by wire
transfer of immediately available funds to the Borrower in accordance with such
wire transfer instructions as the Borrower shall furnish from time to time to
the Liquidity Provider for such purpose.  Each Notice of Borrowing shall be
irrevocable and binding on the Borrower.

                 (f)      Upon the making of any Advance requested pursuant to
a Notice of Borrowing, in accordance with the Borrower's payment instructions,
the Liquidity Provider shall be fully discharged of its obligation hereunder
with respect to such Notice of Borrowing, and the Liquidity Provider shall not
thereafter be obligated to make any further Advances hereunder in respect of
such Notice of Borrowing to the Borrower or to any other Person.  Following the
making of any Advance pursuant to Section 2.02(c) or (d) hereof to fund the
Class C Cash Collateral Account, the Liquidity Provider shall have no interest
in or rights to the Class C Cash Collateral Account, such Advance or any other
amounts from time to time on deposit in the Class C Cash Collateral Account;
provided that the foregoing shall not affect or impair the obligations of the
Subordination Agent to make the distributions contemplated by Section 3.6(e) or
(f) of the Intercreditor Agreement.  By paying to the Borrower proceeds of
Advances requested by the Borrower in accordance with the provisions of this
Agreement, the Liquidity Provider makes no representation as to, and assumes no
responsibility for, the correctness or sufficiency for any purpose of the
amount of the Advances so made and requested.

                 Section 2.03.  Fees.  The Borrower agrees to pay to the
Liquidity Provider the fees set forth in the MSCS Fee Letter.

                 Section 2.04.  Reduction or Termination of the Maximum
Commitment.  (a)  Automatic Reduction.  Promptly following each date on which
the Required Amount is reduced as a result of a reduction in the Pool Balance
of the Class C Certificates or otherwise, the Maximum Commitment shall
automatically be reduced to an amount equal to such reduced Required Amount (as
calculated by the Borrower).  The Borrower shall give notice of any such
automatic reduction of the Maximum Commitment to the Liquidity Provider within
two Business Days thereof.  The failure by the Borrower to furnish any such
notice shall not affect such automatic reduction of the Maximum Commitment.

                 (b)      Termination.  Upon the making of any Provider Advance
or Final Advance hereunder or the occurrence of the Termination Date, the
obligation of the Liquidity Provider to make further Advances hereunder shall
automatically and irrevocably terminate, and the Borrower shall not be entitled
to request any further Borrowing hereunder.

                 Section 2.05.  Repayments of Interest Advances or the Final
Advance.  Subject to Sections 2.06, 2.07 and 2.09 hereof, the Borrower hereby
agrees, without notice of an Advance or demand for repayment from the Liquidity
Provider (which notice and
<PAGE>   15
                                       11

demand are hereby waived by the Borrower), to pay, or to cause to be paid, to
the Liquidity Provider on each date on which the Liquidity Provider shall make
an Interest Advance or the Final Advance, an amount equal to (a) the amount of
such Advance (any such Advance, until repaid, is referred to herein as an
"Unpaid Advance"), plus (b) interest on the amount of each such Unpaid Advance
as provided in Section 3.07 hereof; provided that if (i) the Liquidity Provider
shall make a Provider Advance at any time after making one or more Interest
Advances which shall not have been repaid in accordance with this Section 2.05
or (ii) this Liquidity Facility shall become a Downgraded Facility at any time
when unreimbursed Interest Advances have reduced the Maximum Commitment to
zero, then such Interest Advances shall cease to constitute Unpaid Advances and
shall be deemed to have been changed into an Applied Downgrade Advance for all
purposes of this Agreement (including, without limitation, for the purpose of
determining when such Interest Advance is required to be repaid to the
Liquidity Provider in accordance with Section 2.06 and for the purposes of
Section 2.06(b)). The Borrower and the Liquidity Provider agree that the
repayment in full of each Interest Advance and Final Advance on the date such
Advance is made is intended to be a contemporaneous exchange for new value
given to the Borrower by the Liquidity Provider.

                 Section 2.06.  Repayments of Provider Advances.  (a)  Amounts
advanced hereunder in respect of a Provider Advance shall be deposited in the
Class C Cash Collateral Account, invested and withdrawn from the Class C Cash
Collateral Account as set forth in Sections 3.6(c), (d) and (f) of the
Intercreditor Agreement.  The Borrower agrees to pay to the Liquidity Provider,
on each Regular Distribution Date, commencing on the first Regular Distribution
Date after the making of a Provider Advance, interest on the principal amount
of any such Provider Advance as provided in Section 3.07; provided, however,
that amounts in respect of a Provider Advance withdrawn from the Class C Cash
Collateral Account for the purpose of paying interest on the Class C
Certificates in accordance with Section 3.6(f) of the Intercreditor Agreement
(the amount of any such withdrawal being an "Applied Provider Advance") shall
thereafter (subject to Section 2.06(b)) be treated as an Interest Advance under
this Agreement for purposes of determining the Applicable Liquidity Rate for
interest payable thereon; provided further, however, that if, following the
making of a Provider Advance, the Liquidity Provider delivers a Termination
Notice to the Borrower pursuant to Section 6.01 hereof, such Provider Advance
shall thereafter be treated as a Final Advance under this Agreement for
purposes of determining the Applicable Liquidity Rate for interest payable
thereon.  Subject to Sections 2.07 and 2.09 hereof, immediately upon the
withdrawal of any amounts from the Class C Cash Collateral Account on account
of a reduction in the Required Amount, the Borrower shall repay to the
Liquidity Provider a portion of the Provider Advances in a principal amount
equal to such reduction, plus interest on the principal amount prepaid as
provided in Section 3.07 hereof.

                 (b)      At any time when an Applied Provider Advance (or any
portion thereof) is outstanding, upon the deposit in the Class C Cash
Collateral Account of any
<PAGE>   16
                                       12

amount pursuant to clause "third" of Section 2.4(b) of the Intercreditor
Agreement, clause "third" of Section 3.2 of the Intercreditor Agreement or
clause "fourth" of Section 3.3 of the Intercreditor Agreement (any such amount
being a "Replenishment Amount") for the purpose of replenishing or increasing
the balance thereof up to the Required Amount at such time, (i) the aggregate
outstanding principal amount of all Applied Provider Advances (and of Provider
Advances treated as an Interest Advance for purposes of determining the
Applicable Liquidity Rate for interest payable thereon) shall be automatically
reduced by the amount of such Replenishment Amount and (ii) the aggregate
outstanding principal amount of all Unapplied Provider Advances shall be
automatically increased by the amount of such Replenishment Amount.

                 (c)      Upon the provision of a Replacement Liquidity
Facility in replacement of this Agreement in accordance with Section 3.6(e) of
the Intercreditor Agreement, amounts remaining on deposit in the Class C Cash
Collateral Account after giving effect to any Applied Provider Advance on the
date of such replacement shall be reimbursed to the Liquidity Provider, but
only to the extent such amounts are necessary to repay in full to the Liquidity
Provider all amounts owing to it hereunder.

                 Section 2.07.  Payments to the Liquidity Provider Under the
Intercreditor Agreement.  In order to provide for payment or repayment to the
Liquidity Provider of any amounts hereunder, the Intercreditor Agreement
provides that amounts available and referred to in Articles II and III of the
Intercreditor Agreement, to the extent payable to the Liquidity Provider
pursuant to the terms of the Intercreditor Agreement (including, without
limitation, Section 3.6(f) of the Intercreditor Agreement), shall be paid to
the Liquidity Provider in accordance with the terms thereof.  Amounts so paid
to the Liquidity Provider shall be applied by the Liquidity Provider to
Liquidity Obligations then due and payable in accordance with the Intercreditor
Agreement or, if not provided for in the Intercreditor Agreement, then in such
manner as the Liquidity Provider shall deem appropriate.

                 Section 2.08.  Book Entries.  The Liquidity Provider shall
maintain in accordance with its usual practice an account or accounts
evidencing the indebtedness of the Borrower resulting from Advances made from
time to time and the amounts of principal and interest payable hereunder and
paid from time to time in respect thereof; provided, however, that the failure
by the Liquidity Provider to maintain such account or accounts shall not affect
the obligations of the Borrower in respect of Advances.

                 Section 2.09.  Payments from Available Funds Only.  All
payments to be made by the Borrower under this Agreement shall be made only
from the amounts that constitute Scheduled Payments, Special Payments or
payments under Section 8.1 or 9.1, as the case may be, of the Participation
Agreements and Section 6 of the Note Purchase Agreement and only to the extent
that the Borrower shall have sufficient income or proceeds therefrom to enable
the Borrower to make payments in accordance with the terms hereof
<PAGE>   17
                                       13

after giving effect to the priority of payments provisions set forth in the
Intercreditor Agreement.  The Liquidity Provider agrees that it will look
solely to such amounts to the extent available for distribution to it as
provided in the Intercreditor Agreement and this Agreement and that the
Borrower, in its individual capacity, is not personally liable to it for any
amounts payable or liability under this Agreement except as expressly provided
in this Agreement, the Intercreditor Agreement or any Participation Agreement.
Amounts on deposit in the Class C Cash Collateral Account shall be available to
the Borrower to make payments under this Agreement only to the extent and for
the purposes expressly contemplated in Section 3.6(f) of the Intercreditor
Agreement.

                 Section 2.10.  [Intentionally omitted]

                                  ARTICLE III

                          OBLIGATIONS OF THE BORROWER

                 Section 3.01.  Increased Costs.  The Borrower shall pay to the
Liquidity Provider from time to time such amounts as may be necessary to
compensate the Liquidity Provider for any increased costs incurred by the
Liquidity Provider which are attributable to its making or maintaining any
LIBOR Advances hereunder or its obligation to make any such Advances hereunder,
or any reduction in any amount receivable by the Liquidity Provider under this
Agreement or the Intercreditor Agreement in respect of any such Advances or
such obligation (such increases in costs and reductions in amounts receivable
being herein called "Additional Costs"), resulting from any change after the
date of this Agreement in U.S. federal, state, municipal, or foreign laws or
regulations which changes the basis of taxation of any amounts payable to the
Liquidity Provider under this Agreement in respect of any such Advances (other
than Excluded Taxes).  The Liquidity Provider agrees to use reasonable efforts
(consistent with applicable legal and regulatory restrictions) to change the
jurisdiction of its Lending Office if making such change would avoid the need
for, or reduce the amount of, any amount payable under this Section that may
thereafter accrue and would not, in the reasonable judgment of the Liquidity
Provider, be otherwise disadvantageous to the Liquidity Provider.

                 The Liquidity Provider will notify the Borrower of any event
occurring after the date of this Agreement that will entitle the Liquidity
Provider to compensation pursuant to this Section 3.01 as promptly as
practicable after it obtains knowledge thereof and determines to request such
compensation, which notice shall describe in reasonable detail the calculation
of the amounts owed under this Section.  Determinations by the Liquidity
Provider for purposes of this Section 3.01 of the effect of any Regulatory
Change on its costs of making or maintaining Advances or on amounts receivable
by it in respect of Advances, and of the additional amounts required to
compensate the Liquidity Provider in respect of any Additional Costs, shall be
prima facie evidence of the amount owed under this Section.
<PAGE>   18
                                       14


                 Section 3.02.  Capital Adequacy.  If (1) the adoption, after
the date hereof, of any applicable governmental law, rule or regulation
regarding capital adequacy, (2) any change, after the date hereof, in the
interpretation or administration of any such law, rule or regulation by any
central bank or other governmental authority charged with the interpretation or
administration thereof or (3) compliance by the Liquidity Provider or any
corporation controlling the Liquidity Provider with any applicable guideline or
request of general applicability, issued after the date hereof, by any central
bank or other governmental authority (whether or not having the force of law)
that constitutes a change of the nature described in clause (2), has the effect
of requiring an increase in the amount of capital required to be maintained by
the Liquidity Provider or any corporation controlling the Liquidity Provider,
and such increase is based upon the Liquidity Provider's obligations hereunder
and other similar obligations, the Borrower shall pay to the Liquidity Provider
from time to time such additional amount or amounts as are necessary to
compensate the Liquidity Provider for such portion of such increase as shall be
reasonably allocable to the Liquidity Provider's obligations to the Borrower
hereunder.  The Liquidity Provider agrees to use reasonable efforts (consistent
with applicable legal and regulatory restrictions) to change the jurisdiction
of its Lending Office if making such change would avoid the need for, or reduce
the amount of, any amount payable under this Section that may thereafter accrue
and would not, in the reasonable judgment of the Liquidity Provider, be
otherwise materially disadvantageous to the Liquidity Provider.

                 The Liquidity Provider will notify the Borrower of any event
occurring after the date of this Agreement that will entitle the Liquidity
Provider to compensation pursuant to this Section 3.02 as promptly as
practicable after it obtains knowledge thereof and determines to request such
compensation, which notice shall describe in reasonable detail the calculation
of the amounts owed under this Section.  Determinations by the Liquidity
Provider for purposes of this Section 3.02 of the effect of any increase in the
amount of capital required to be maintained by the bank and of the amount
allocable to the Liquidity Provider's obligations to the Borrower hereunder
shall be prima facie evidence of the amounts owed under this Section.

                 Section 3.03.  Payments Free of Deductions.  All payments made
by the Borrower under this Agreement shall be made free and clear of, and
without reduction for or on account of, any present or future stamp or other
taxes, levies, imposts, duties, charges, fees, deductions, withholdings,
restrictions or conditions of any nature whatsoever now or hereafter imposed,
levied, collected, withheld or assessed, excluding Excluded Taxes (such
non-excluded taxes being referred to herein, collectively, as "Non-Excluded
Taxes" and, individually, as a "Non-Excluded Tax").  If any Non-Excluded Taxes
are required to be withheld from any amounts payable to the Liquidity Provider
under this Agreement, the amounts so payable to the Liquidity Provider shall be
increased to the extent necessary to yield to the Liquidity Provider (after
payment of all Non-Excluded Taxes) interest or any other such amounts payable
under this Agreement at the rates or in the amounts specified in
<PAGE>   19
                                       15

this Agreement.  The Liquidity Provider agrees to use reasonable efforts
(consistent with its internal policy and legal and regulatory restrictions) to
change the jurisdiction of its Lending Office if making such change would avoid
the need for, or reduce the amount of, any such additional amounts that may
thereafter accrue and would not, in the reasonable judgment of the Liquidity
Provider, be otherwise disadvantageous to the Liquidity Provider.  From time to
time upon the reasonable request of the Borrower, the Liquidity Provider agrees
to provide to the Borrower two original Internal Revenue Service Forms 1001 or
4224, as appropriate, or any successor or other form prescribed by the Internal
Revenue Service, certifying that the Liquidity Provider is exempt from or
entitled to a reduced rate of United States withholding tax on payments
pursuant to this Agreement.

                 (b)      All payments (including, without limitation,
Advances) made by the Liquidity Provider under this Agreement shall be made
free and clear of, and without reduction for or on account of, any Taxes.  If
any Taxes are required to be withheld or deducted from any amounts payable to
the Borrower under this Agreement, the Liquidity Provider shall (i) within the
time prescribed therefor by applicable law pay to the appropriate governmental
or taxing authority the full amount of any such Taxes (and any additional Taxes
in respect of the payment required under clause (ii) hereof) and make such
reports or returns in connection therewith at the time or times and in the
manner prescribed by applicable law, and (ii) pay to the Borrower an additional
amount which (after deduction of all such Taxes) will be sufficient to yield to
the Borrower the full amount which would have been received by it had no such
withholding or deduction been made.  Within 30 days after the date of each
payment hereunder, the Liquidity Provider shall furnish to the Borrower the
original or a certified copy of (or other documentary evidence of) the payment
of the Taxes applicable to such payment.

                 Section 3.04.  Payments.  The Borrower shall make or cause to
be made each payment to the Liquidity Provider under this Agreement so as to
cause the same to be received by the Liquidity Provider not later than 1:00
P.M.  (New York City time) on the day when due.  The Borrower shall make all
such payments in lawful money of the United States of America, to the Liquidity
Provider in immediately available funds, by wire transfer to Citibank, N.A.,
New York, NY, ABA# 021000089, Account Name: Morgan Stanley Capital Services,
Inc., Account # 4072-4601, Reference: Atlas Air, Inc., 1998-1C.

                 Section 3.05.  Computations.  All computations of interest
based on the Base Rate shall be made on the basis of a year of 365 or 366 days,
as the case may be, and all computations of interest based on the LIBOR Rate
shall be made on the basis of a year of 360 days, in each case for the actual
number of days (including the first day but excluding the last day) occurring
in the period for which such interest is payable.

                 Section 3.06.  Payment on Non-Business Days.  Whenever any
payment to be made hereunder shall be stated to be due on a day other than a
Business Day, such payment
<PAGE>   20
                                       16

shall be made on the next succeeding Business Day and no additional interest
shall be due as a result (and if so made, shall be deemed to have been made
when due).  If any payment in respect of interest on an Advance is so deferred
to the next succeeding Business Day, such deferral shall not delay the
commencement of the next Interest Period for such Advance (if such Advance is a
LIBOR Advance) or reduce the number of days for which interest will be payable
on such Advance on the next interest payment date for such Advance.

                 Section 3.07.  Interest.  (a)  Subject to Section 2.09, the
Borrower shall pay, or shall cause to be paid, without duplication, interest on
(i) the unpaid principal amount of each Advance from and including the date of
such Advance (or, in the case of an Applied Provider Advance, from and
including the date on which the amount thereof was withdrawn from the Class C
Cash Collateral Account to pay interest on the Class C Certificates) to but
excluding the date such principal amount shall be paid in full (or, in the case
of an Applied Provider Advance, the date on which the Class C Cash Collateral
Account is fully replenished in respect of such Advance) and (ii) any other
amount due hereunder (whether fees, commissions, expenses or other amounts or,
to the extent permitted by law, installments of interest on Advances or any
such other amount) which is not paid when due (whether at stated maturity, by
acceleration or otherwise) from and including the due date thereof to but
excluding the date such amount is paid in full, in each such case, at a
fluctuating interest rate per annum for each day equal to the Applicable
Liquidity Rate (as defined below) for such Advance or such other amount as in
effect for such day, but in no event at a rate per annum greater than the
maximum rate permitted by applicable law; provided, however, that, if at any
time the otherwise applicable interest rate as set forth in this Section 3.07
shall exceed the maximum rate permitted by applicable law, then any subsequent
reduction in such interest rate will not reduce the rate of interest payable
pursuant to this Section 3.07 below the maximum rate permitted by applicable
law until the total amount of interest accrued equals the amount of interest
that would have accrued if such otherwise applicable interest rate as set forth
in this Section 3.07 had at all times been in effect.

                 (b)      Except as provided in clause (e) below, each Advance
will be either a Base Rate Advance or a LIBOR Advance as provided in this
Section.  Each such Advance will be a Base Rate Advance for the period from the
date of its borrowing to (but excluding) the third Business Day following the
Liquidity Provider's receipt of the Notice of Borrowing for such Advance.
Thereafter, such Advance shall be a LIBOR Advance; provided that the Borrower
(at the direction of the Controlling Party), so long as the Liquidity Provider
is not the Controlling Party) may (x) convert the Final Advance into a Base
Rate Advance on the last day of an Interest Period for such Advance by giving
the Liquidity Provider no less than four Business Days' prior written notice of
such election or (y) elect to maintain the Final Advance as a Base Rate Advance
by not requesting a conversion of the Final Advance to a LIBOR Advance under
Clause (5) of the applicable Notice of Borrowing.

                                       17

                 (c)      Each LIBOR Advance shall bear interest during each
Interest Period at a rate per annum equal to the LIBOR Rate for such Interest
Period plus the Applicable Margin for such LIBOR Advance, payable in arrears on
the last day of such Interest Period and, in the event of the payment of
principal of such LIBOR Advance on a day other than such last day, on the date
of such payment (to the extent of interest accrued on the amount of principal
repaid).

                 (d)      Each Base Rate Advance shall bear interest at a rate
per annum equal to the Base Rate plus the Applicable Margin for such Base Rate
Advance, payable in arrears on each Regular Distribution Date and, in the event
of the payment of principal of such Base Rate Advance on a day other than a
Regular Distribution Date, on the date of such payment (to the extent of
interest accrued on the amount of principal repaid).

                 (e)      Each Unapplied Downgrade Advance (i) during the
period from and including the date of the making of such Unapplied Downgrade
Advance through but excluding the Expiry Date (or, if earlier, the date of
repayment thereof or of conversion thereof into a Final Advance), shall bear
interest at a rate per annum equal to the LIBOR Rate for such Interest Period
plus 0.40% on the amount of such Unapplied Downgrade Advance from time to time
during such period, payable in arrears on each Regular Distribution Date and
(ii) thereafter, shall be a LIBOR Advance and shall bear interest in accordance
with clause (c) above.

                 (f)      [Intentionally omitted]

                 (g)      Each amount not paid when due hereunder (whether
fees, commissions, expenses or other amounts or, to the extent permitted by
applicable law, installments of interest on Advances but excluding Advances)
shall bear interest at a rate per annum equal to the Base Rate plus 2.00% until
paid.

                 (h)      Each change in the Base Rate shall become effective
immediately.  The rates of interest specified in this Section 3.07 with respect
to any Advance or other amount shall be referred to as the "Applicable
Liquidity Rate".

                 Section 3.08.  Replacement of Borrower.  From time to time and
subject to the successor Borrower's meeting the eligibility requirements set
forth in Section 6.9 of the Intercreditor Agreement applicable to the
Subordination Agent, upon the effective date and time specified in a written
and completed Notice of Replacement Subordination Agent in substantially the
form of Annex V attached hereto (a "Notice of Replacement Subordination Agent")
delivered to the Liquidity Provider by the then Borrower, the successor
Borrower designated therein shall be substituted for as the Borrower for all
purposes hereunder.

                 Section 3.09.  Funding Loss Indemnification.  The Borrower
shall pay to the Liquidity Provider, upon the request of the Liquidity
Provider, such amount or amounts as shall be sufficient (in the reasonable
opinion of the Liquidity Provider) to compensate it for any loss, cost, or
expense incurred by reason of the liquidation or redeployment of deposits or
other funds acquired by the Liquidity Provider to fund or maintain any LIBOR
Advance (but excluding loss of anticipated profits) incurred as a result of:

                 (1)      Any repayment of a LIBOR Advance on a date other than
         the last day of the Interest Period for such Advance; or

                 (2)      Any failure by the Borrower to borrow a LIBOR Advance
         on the date for borrowing specified in the relevant notice under
         Section 2.02.

                 Section 3.10.  Illegality.  Notwithstanding any other
provision in this Agreement, if any change in any applicable law, rule or
regulation, or any change in the interpretation or administration thereof by
any governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by the Liquidity
Provider (or its Lending Office) with any request or directive (whether or not
having the force of law) of any such authority, central bank or comparable
agency shall make it unlawful or impossible for the Liquidity Provider (or its
Lending Office) to maintain or fund its LIBOR Advances, then upon notice to the
Borrower by the Liquidity Provider, the outstanding principal amount of the
LIBOR Advances shall be converted to Base Rate Advances (a) immediately upon
demand of the Liquidity Provider, if such change or compliance with such
request, in the judgment of the Liquidity Provider, requires immediate
repayment; or (b) at the expiration of the last Interest Period to expire
before the effective date of any such change or request.

described in Sections 3.01, 3.02 or 7.07 hereof or in the MSCS Fee Letter
(regardless of whether indemnified against pursuant to said Sections or in such
MSCS Fee Letter)), that may be imposed, incurred by or asserted against any
Liquidity Indemnitee, in any way relating to, resulting from, or arising out of
or in connection with any action, suit or proceeding by any third party against
such Liquidity Indemnitee and relating to this Agreement, the MSCS Fee Letter,
the Intercreditor Agreement or any Financing Agreement; provided, however, that
the Borrower shall not be required to indemnify, protect, defend and hold
harmless any Liquidity Indemnitee in respect of any Expense of such Liquidity
Indemnitee (i) to the extent such Expense is attributable to the gross
negligence or willful misconduct of such Liquidity Indemnitee or any other
Liquidity Indemnitee, (ii) ordinary and usual operating overhead expense, or
(iii) attributable to the failure by such Liquidity Indemnitee or any other
Liquidity Indemnitee to perform or observe any agreement, covenant or condition
on its part to be performed or observed in this Agreement, the Intercreditor
Agreement, the MSCS Fee Letter or any other Operative Agreement to which it is
a party.  The indemnities contained in Section 9.1 or 8.1, as the case may be,

3.03, 3.09, 7.05 and 7.07 hereof, shall survive the termination of  this

                 Section 7.06.  Liability of the Liquidity Provider.  (a)
Neither the Liquidity Provider nor any of its officers, employees, directors or
affiliates shall be liable or responsible for: (i) the use which may be made of
the Advances or any acts or omissions of the Borrower or any beneficiary or
transferee in connection therewith; (ii) the validity, sufficiency or
genuineness of documents, or of any endorsement thereon, even if such documents
should prove to be in any or all respects invalid, insufficient, fraudulent or
forged; or (iii) the making of Advances by the Liquidity Provider against
delivery of a Notice of Borrowing and other documents which do not comply with
the terms hereof; provided, however, that the Borrower shall have a claim
against the Liquidity Provider, and the Liquidity Provider shall be liable to
the Borrower, to the extent of any damages suffered by the Borrower which were
the result of (A) the Liquidity Provider's willful misconduct or negligence in
determining whether documents presented hereunder comply with the terms hereof,
or (B) any breach by the Liquidity Provider of any of the terms of this
Agreement, including, but not limited to, the Liquidity Provider's failure to
make lawful payment hereunder after the delivery to it by the Borrower of a
Notice of Borrowing strictly complying with the terms and conditions hereof.

                 (b)      Neither the Liquidity Provider nor any of its
officers, employees, director or affiliates shall be liable or responsible in
any respect for (i) any error, omission, interruption or delay in transmission,
dispatch or delivery of any message or advice, however transmitted, in
connection with this Agreement or any Notice of Borrowing delivered hereunder,
or (ii) any action, inaction or omission which may be taken by it in good
faith, absent willful misconduct or negligence (in which event the extent of
the Liquidity Provider's potential liability to the Borrower shall be limited
as set forth in the immediately preceding paragraph), in connection with this
Agreement or any Notice of Borrowing.

                 Section 7.07.  Costs, Expenses and Taxes.  The Borrower agrees
to pay, or cause to be paid (A) on the Effective Date and on such later date or
dates on which the Liquidity Provider shall make demand, all reasonable out-of-
pocket costs and expenses (including, without limitation, the reasonable fees
and expenses of outside counsel for the Liquidity Provider) of the Liquidity
Provider in connection with the preparation, negotiation, execution, delivery,
filing and recording of this Agreement, any other Operative Agreement and any
other documents which may be delivered in connection with this Agreement and
(B) on demand, all reasonable costs and expenses (including reasonable counsel
fees and expenses) of the Liquidity Provider in connection with (i) the
enforcement of this Agreement or any other Operative Agreement, (ii) the
modification or amendment of, or supplement to, this Agreement or any other
Operative Agreement or such other documents which may be delivered in
connection herewith or therewith (whether or not the same shall become
effective) or (iii) any action or proceeding relating to any order, injunction,
or other process or decree restraining or seeking to restrain the Liquidity
Provider from paying any amount under this Agreement, the Intercreditor
Agreement or any other Operative Agreement or otherwise affecting the
application of funds in the Class C Cash Collateral Account.  In
<PAGE>   29
                                       25

addition, the Borrower shall pay any and all recording, stamp and other similar
taxes and fees payable or determined to be payable in connection with the
execution, delivery, filing and recording of this Agreement, any other
Operative Agreement and such other documents, and agrees to save the Liquidity
Provider harmless from and against any and all liabilities with respect to or
resulting from any delay in paying or omission to pay such taxes or fees.

                 Section 7.08.  Binding Effect; Participations.

                 (a)      This Agreement shall be binding upon and inure to the
benefit of the Borrower and the Liquidity Provider and their respective
successors and assigns, except that neither the Liquidity Provider (except as
otherwise provided in this Section 7.08) nor (except as contemplated by Section
3.08) the Borrower shall have the right to assign its rights or obligations
hereunder or any interest herein without the prior written consent of the other
party, subject to the requirements of Section 7.08(b). The Liquidity Provider
may grant participations herein or in any of its rights hereunder (including,
without limitation, funded participations and participations in rights to
receive interest payments hereunder) and under the other Operative Agreements
to such Persons as the Liquidity Provider may in its sole discretion select,
subject to the requirements of Section 7.08(b). No such participation by the
Liquidity Provider, however, will relieve the Liquidity Provider of its
obligations hereunder.  In connection with any participation or any proposed
participation, the Liquidity Provider may disclose to the participant or the
proposed participant any information that the Borrower is required to deliver
or to disclose to the Liquidity Provider pursuant to this Agreement.  The
Borrower acknowledges and agrees that the Liquidity Provider's source of funds
may derive in part from its participants (other than Atlas).  Accordingly,
references in this Agreement and the other Operative Agreements to
determinations, reserve and capital adequacy requirements, increased costs,
reduced receipts, additional amounts due pursuant to Section 3.03(a) and the
like as they pertain to the Liquidity Provider shall be deemed also to include
those of each of its participants (subject, in each case, to the maximum amount
that would have been incurred by or attributable to the Liquidity Provider
directly if the Liquidity Provider, rather than the participant, had held the
interest participated).

                 (b)      If, pursuant to subsection (a) above, the Liquidity
Provider sells any participation in this Agreement to any bank or other entity
(each, a "Transferee"), then, concurrently with the effectiveness of such
participation, the Transferee shall (i) represent to the Liquidity Provider
(for the benefit of the Liquidity Provider and the Borrower) either (A) that it
is incorporated under the laws of the United States or a state thereof or (B)
that under applicable law and treaties, no taxes will be required to be
withheld with respect to any payments to be made to such Transferee in respect
of this Agreement, (ii) furnish to the Liquidity Provider and the Borrower
either (x) a statement that it is incorporated under the laws of the United
States or a state thereof or (y) if it is not so incorporated, two copies of a
properly completed United States Internal Revenue Service Form 4224 or Form
1001, as appropriate, or other applicable form, certificate or document
prescribed by the Internal
<PAGE>   30
                                       26

Revenue Service certifying, in each case, such Transferee's entitlement to a
complete exemption from United States federal withholding tax in respect to any
and all payments to be made hereunder, and (iii) agree (for the benefit of the
Liquidity Provider and the Borrower) to provide the Liquidity Provider and the
Borrower a new Form 4224 or Form 1001, as appropriate, (A) on or before the
date that any such form expires or becomes obsolete or (B) after the occurrence
of any event requiring a change in the most recent form previously delivered by
it and prior to the immediately following due date of any payment by the
Borrower hereunder, certifying in the case of a Form 1001 or Form 4224 that
such Transferee is entitled to a complete exemption from United States federal
withholding tax on payments under this Agreement.  Unless the Borrower has
received forms or other documents reasonably satisfactory to it (and required
by applicable law) indicating that payments hereunder are not subject to United
States federal withholding tax, the Borrower will withhold taxes as required by
law from such payments at the applicable statutory rate.

                 Section 7.09.  Severability.  Any provision of this Agreement
which is prohibited, unenforceable or not authorized in any jurisdiction shall,
as to such jurisdiction, be ineffective to the extent of such prohibition,
unenforceability or nonauthorization without invalidating the remaining
provisions hereof or affecting the validity, enforceability or legality of such
provision in any other jurisdiction.

                 Section 7.10.  GOVERNING LAW.  THIS AGREEMENT SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW
YORK.

                 Section 7.11.  Submission to Jurisdiction; Waiver of Jury
Trial; Waiver of Immunity.  (a)  Each of the parties hereto hereby irrevocably
and unconditionally:

         (i)     submits for itself and its property in any legal action or
                 proceeding relating to this Agreement or any other Operative
                 Agreement, or for recognition and enforcement of any judgment
                 in respect hereof or thereof, to the nonexclusive general
                 jurisdiction of the courts of the State of New York, the
                 courts of the United States of America for the Southern
                 District of New York, and the appellate courts from any
                 thereof;

         (ii)    consents that any such action or proceeding may be brought in

                 hereafter have to the venue of any such action or proceeding
                 in any such court or that such action or  proceeding was
                 brought in an inconvenient court and agrees not to plead or
                 claim the same;

         (iii)   agrees that service of process in any such action or
                 proceeding may be effected by  mailing a copy thereof by
                 registered or certified mail (or any substantially

                 at its address set forth in Section 7.02 hereof, or at such
                 other address of which the Liquidity Provider shall have been
                 notified pursuant thereto; and

         (iv)    agrees that nothing herein shall affect the right to effect
                 service of process in any other manner permitted by law or
                 shall limit the right to sue in any other jurisdiction.

                 (b)      THE BORROWER AND THE LIQUIDITY PROVIDER EACH HEREBY
AGREE TO WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF
ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM
RELATING TO THE SUBJECT MATTER OF THIS AGREEMENT AND THE RELATIONSHIP THAT IS
BEING ESTABLISHED, including, without limitation, contract claims, tort claims,
breach of duty claims and all other common law and statutory claims.  The
Borrower and the Liquidity Provider each warrant and represent that it has
reviewed this waiver with its legal counsel, and that it knowingly and
voluntarily waives its jury trial rights following consultation with such legal
counsel.  THIS WAIVER IS IRREVOCABLE, AND CANNOT BE MODIFIED EITHER ORALLY OR
IN WRITING, AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS,
SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT.

                 Section 7.12.  Execution in Counterparts.  This Agreement may
be executed in any number of counterparts and by different parties hereto on
separate counterparts, each of which counterparts, when so executed and
delivered, shall be deemed to be an original and all of which counterparts,
taken together, shall constitute but one and the same Agreement.

                 Section 7.13.  Entirety.  This Agreement, the Intercreditor
Agreement and the other Operative Agreements to which the Liquidity Provider is
a party constitute the entire agreement of the parties hereto with respect to
the subject matter hereof and supersedes all prior understandings and
agreements of such parties.

                 Section 7.14.  Headings.  Section headings in this Agreement
are included herein for convenience of reference only and shall not constitute
a part of this Agreement for any other purpose.

                 Section 7.15.  Transfer.  The Liquidity Provider hereby
acknowledges and consents to the Transfer contemplated by the Assignment and
Assumption Agreement.

Pass Through Trust 1998-B ("Counterparty"), Morgan Stanley, Dean Witter,
Discover & Co., a Delaware corporation (hereinafter "MSDWD"), hereby
irrevocably and unconditionally guarantees to Counterparty, with effect from
the date of the Agreement, the due and punctual payment of all amounts payable
by MSCS under the Agreement when the same shall become due and payable, whether
on scheduled payment dates, upon demand, upon declaration of termination or
otherwise, in accordance with the terms of the Agreement and giving effect to
any applicable grace period. Upon failure of MSCS punctually to pay any such
amounts, and upon written demand by Counterparty to MSDWD at its address set
forth in the signature block of this Guarantee (or to such other address as
MSDWD may specify in writing), MSDWD agrees to pay or cause to be paid such
amounts; provided that delay by Counterparty in giving such demand shall in no
event affect MSDWD's obligations under this Guarantee.

                  MSDWD hereby agrees that its obligations hereunder shall be
unconditional and will not be discharged except by complete payment of the
amounts payable under the Agreement, irrespective of any claim as to the
Agreement's validity, regularity or enforceability or the lack of authority of
MSCS to execute or deliver the Agreement; or any change in or amendment to the
Agreement; or any waiver or consent by Counterparty with respect to any
provisions thereof; or the absence of any action to enforce the Agreement or
the recovery of any judgment against MSCS or of any action to enforce a
judgment against MSCS under the Agreement; or any similar circumstance which
might otherwise constitute a legal or equitable discharge or defense of a
guarantor generally. MSDWD hereby waives diligence, presentment, demand on MSCS
for payment or otherwise (except as provided hereinabove), filing of claims,
requirement of a prior proceeding against MSCS and protest or notice, except as
provided for in the Agreement with respect to amounts payable by MSCS. If at
any time payment under the Agreement is rescinded or must be otherwise restored
or returned by Counterparty upon the insolvency, bankruptcy or reorganization
of MSCS or MSDWD or otherwise, MSDWD's obligations hereunder with respect to
such payment shall be reinstated upon such restoration or return being made by
Counterparty.

         MSDWD represents to Counterparty as of the date hereof, which
representations will be deemed to be repeated by MSDWD on each date on which a
Transaction is entered into, that:

         (1) it is duly organized and validly existing under the laws of the
jurisdiction of its incorporation and has full power and legal right to execute
and deliver this Guarantee and to perform the provisions of this Guarantee on
its part to be performed;

         (2) its execution, delivery and performance of this Guarantee have
been and remain duly authorized by all necessary corporate action and do not
contravene any provision of its certificate of incorporation or by-laws or any
law, regulation or contractual restriction binding on it or its assets;




<PAGE>   2

         (3) all consents, authorizations, approvals and clearances (including,
without limitation, any necessary exchange control approval) and notifications,
reports and registrations requisite for its due execution, delivery and
performance of this Guarantee have been obtained from or, as the case may be,
filed with the relevant governmental authorities having jurisdiction and remain
in full force and effect and all conditions thereof have been duly complied
with and no other action by, and no notice to or filing with, any governmental
authority having jurisdiction is required for such execution, delivery or
performance; and

         (4) this Guarantee is its legal, valid and binding obligation
enforceable against it in accordance with its terms except as enforcement
hereof may be limited by applicable bankruptcy, insolvency, reorganization or
other similar laws affecting the enforcement of creditors' rights or by general
equity principles.

         By accepting this Guarantee and entering into the Agreement,
Counterparty agrees that MSDWD shall be subrogated to all rights of
Counterparty against MSCS in respect of any amounts paid by MSDWD pursuant to
this Guarantee, provided that MSDWD shall be entitled to enforce or to receive
any payment arising out of or based upon such right of subrogation only to the
extent that it has paid all amounts payable by MSCS under the Agreement.

         This Guarantee shall be governed by and construed in accordance with
the laws of the State of New York. All capitalized terms not otherwise defined
herein shall have the respective meanings assigned to them in the Agreement.

                       TRUST ACCOUNTS; CONTROLLING PARTY

                 SECTION 2.1.  Agreement to Terms of Subordination; Payments
from Monies Received Only.  (a)  Each Trustee hereby acknowledges and agrees to
the terms of subordination set forth in this Agreement in respect of each Class
of Certificates and agrees to enforce such provisions and cause all payments in
respect of the Equipment Notes and the Liquidity Facilities to be applied in
accordance with the terms of this Agreement.  In addition, each Trustee hereby
agrees to cause the Equipment Notes purchased by the related Trust to be
registered in the name of the Subordination Agent or its nominee, as agent and
trustee for such Trustee, to be held in trust by the Subordination Agent solely
for the purpose of facilitating the enforcement of the subordination and other
provisions of this Agreement.

                 (b)      Except as otherwise expressly provided in the next
succeeding sentence of this Section 2.1, all payments to be made by the
Subordination Agent hereunder shall be made only from amounts received by it
that constitute Scheduled Payments, Special Payments, payments under Section
9.1 of the Participation Agreements or payments under Sections 6 and 7 of the
Note Purchase Agreement, and only to the extent that the Subordination Agent
shall have received sufficient income or proceeds therefrom to enable it to
make such payments in accordance with the terms hereof.  Each of the Trustees
and the Subordination Agent hereby agrees and, as provided in each Trust
Agreement, each Certificateholder, by its acceptance of a Certificate, and each
Liquidity Provider, by entering into the Liquidity Facility to which it is a
party, has agreed to look solely to such amounts to the extent available for
distribution to it as provided in this Agreement and to the relevant Deposits
and that none of the Trustees, Owner Trustees, Loan Trustees, Owner
Participants nor the Subordination Agent is personally liable to any of them
for any amounts payable or any liability under this Agreement, any Trust
Agreement, any Liquidity Facility or such Certificate, except (in the case of
the Subordination Agent) as expressly provided herein or (in the case of the
Trustees) as expressly provided in each Trust Agreement or (in the case of the
Owner Trustees and the Loan Trustees) as expressly provided in any Operative
Agreement.

                 SECTION 2.2.  Trust Accounts.  (a)  Upon the execution of this
Agreement, the Subordination Agent shall establish and maintain in its name (i)
the Collection Account as an Eligible Deposit Account, bearing a designation
clearly indicating that the funds deposited therein are held in trust for the
benefit of the Trustees, the Certificateholders and the Liquidity Providers,
and (ii) as a sub-account in the Collection Account, the Special Payments
Account as an Eligible Deposit Account, bearing a designation clearly
indicating that the funds deposited therein are held in trust for the benefit
of the Trustees, the Certificateholders and the Liquidity Providers.  The
Subordination Agent shall establish and maintain the Cash Collateral Accounts
pursuant to and under the circumstances set forth in Section 3.6(f) hereof.
Upon such establishment and maintenance under Section 3.6(f) hereof,





                                       24
<PAGE>   29
the Cash Collateral Accounts shall, together with the Collection Account,
constitute the "Trust Accounts" hereunder.

                 (b)      Funds on deposit in the Trust Accounts shall be
invested and reinvested by the Subordination Agent in Eligible Investments
selected by the Subordination Agent if such investments are reasonably
available and have maturities no later than the earlier of (i) 90 days
following the date of such investment and (ii) the Business Day immediately
preceding the Regular Distribution Date or the date of the related distribution
pursuant to Section 2.4 hereof, as the case may be, next following the date of
such investment; (or, in the case of any amount on deposit in the Cash
Collateral Account with respect to any Liquidity Facility (with respect to such
Liquidity Facility, the "Relevant Amount"), (A) in the case of a portion of the
Relevant Amount equal to the amount scheduled to be paid to the Liquidity
Provider with respect to such Liquidity Facility on the Regular Distribution
Date next following the date of such investment in accordance with clause (iv),
(v) or (vi) of Section 3.6(f), the Business Day immediately preceding such
Regular Distribution Date, or (B) in the case of a portion of the Relevant
Amount equal to the Relevant Amount minus the amount described in clause (A)
above, the Business Day immediately preceding the scheduled Interest Payment
Date with respect to such Liquidity Facility next following the date of such
investment); provided, however, that following the making of a Downgrade
Drawing or a Non-Extension Drawing under any Liquidity Facility, the
Subordination Agent shall invest and reinvest such amounts in Eligible
Investments at the direction of Atlas; provided, however, that upon the
occurrence and during the continuation of a Triggering Event, the Subordination
Agent shall invest and reinvest such amounts in accordance with the written
instructions of the Controlling Party.  Unless otherwise expressly provided in
this Agreement (including, without limitation, with respect to Investment
Earnings on deposit in the Cash Collateral Accounts, Section 3.6(f) hereof),
any Investment Earnings shall be deposited in the Collection Account when
received by the Subordination Agent and shall be applied by the Subordination
Agent in the same manner as the other amounts on deposit in the Collection
Account are to be applied and any losses shall be charged against the principal
amount invested, in each case net of the Subordination Agent's reasonable fees
and expenses in making such investments.  The Subordination Agent shall not be
liable for any loss resulting from any investment, reinvestment or liquidation
required to be made under this Agreement other than by reason of its willful
misconduct or gross negligence.  Eligible Investments and any other investment
required to be made hereunder shall be held to their maturities except that any
such investment may be sold (without regard to its maturity) by the
Subordination Agent without instructions whenever such sale is necessary to
make a distribution required under this Agreement.  Uninvested funds held
hereunder shall not earn or accrue interest.

                 (c)      The Subordination Agent shall possess all right,
title and interest in all funds on deposit from time to time in the Trust
Accounts and in all proceeds thereof (including all income thereon, except as
otherwise expressly provided herein with respect to Investment Earnings).  The
Trust Accounts shall be held in trust by the Subordination Agent under the sole
dominion and control of the Subordination Agent for the benefit of the
Trustees, the Certificateholders and the Liquidity Providers, as the case may
be.  If, at any





                                       25
<PAGE>   30
time, any of the Trust Accounts ceases to be an Eligible Deposit Account, the
Subordination Agent shall within 10 Business Days (or such longer period, not
to exceed 30 calendar days, to which each Rating Agency may consent) establish
a new Collection Account, Special Payments Account or Cash Collateral Account,
as the case may be, as an Eligible Deposit Account and shall transfer any cash
and/or any investments to such new Collection Account, Special Payments Account
or Cash Collateral Account, as the case may be.  So long as WTC is an Eligible
Institution, the Trust Accounts shall be maintained with it as Eligible Deposit
Accounts.

                 SECTION 2.3.  Deposits to the Collection Account and Special
Payments Account.  (a)  The Subordination Agent shall, upon receipt thereof,
deposit in the Collection Account all Scheduled Payments received by it.

                 (b)      The Subordination Agent shall, on each date when one
or more Special Payments are made to the Subordination Agent as holder of the
Equipment Notes, deposit in the Special Payments Account the aggregate amount
of such Special Payments.

                 SECTION 2.4.  Distributions of Special Payments.  (a)  Notice
of Special Payment.  Except as provided in Section 2.4(e) below, upon receipt
by the Subordination Agent, as registered holder of the Equipment Notes, of any
notice of a Special Payment (or, in the absence of any such notice, upon
receipt by the Subordination Agent of a Special Payment), the Subordination
Agent shall promptly give notice thereof to each Trustee and the Liquidity
Providers.  The Subordination Agent shall promptly calculate the amount of the
redemption or purchase of Equipment Notes or the amount of any Overdue
Scheduled Payment, as the case may be, comprising such Special Payment under
the applicable Indenture or Indentures and shall promptly send to each Trustee
a Written Notice of such amount and the amount allocable to each Trust.  Such
Written Notice shall also set the distribution date for such Special Payment (a
"Special Distribution Date"), which shall be the Business Day which immediately
follows the later to occur of (x) the 15th day after the date of such Written
Notice or (y) the date the Subordination Agent has received or expects to
receive such Special Payment.  Amounts on deposit in the Special Payments
Account shall be distributed in accordance with Sections 2.4(b) and 2.4(c)
hereof, as applicable.

                 (b)      Redemptions and Purchases of Equipment Notes.  (i) So
long as no Triggering Event shall have occurred (whether or not continuing),
the Subordination Agent shall make distributions pursuant to this Section
2.4(b) of amounts on deposit in the Special Payments Account on account of the
redemption, purchase (including, without limitation, a purchase resulting from
a sale of the Equipment Notes permitted by Article IV hereof) or prepayment of
all of the Equipment Notes issued pursuant to an Indenture on the Special
Distribution Date for such Special Payment in the following order of priority:

         first, such amount as shall be required to pay (A) all accrued and
         unpaid Liquidity Expenses then in arrears plus (B) the product of (x)
         the aggregate amount of all accrued and unpaid Liquidity Expenses not
         in arrears to such Special Payment Date





                                       26
<PAGE>   31
         multiplied by (y) a fraction, the numerator of which is the aggregate
         outstanding principal amount of Equipment Notes being redeemed,
         purchased or prepaid on such Special Payment Date and the denominator
         of which is the aggregate outstanding principal amount of all
         Equipment Notes, shall be distributed to the Liquidity Providers pari
         passu on the basis of the amount of Liquidity Expenses owed to each
         Liquidity Provider;

         second, such amount as shall be required to pay (A) all accrued and
         unpaid interest then in arrears on all Liquidity Obligations
         (including interest accrued and unpaid on any Interest Drawing or any
         Applied Provider Advance (as defined in any Liquidity Facility)) plus
         (B) the product of (x) the aggregate amount of all accrued and unpaid
         interest on all Liquidity Obligations not in arrears to such Special
         Payment Date (at the rate provided in the applicable Liquidity
         Facility) multiplied by (y) a fraction, the numerator of which is the
         aggregate outstanding principal amount of Equipment Notes being
         redeemed, purchased or prepaid on such Special Payment Date and the
         denominator of which is the aggregate outstanding principal amount of
         all Equipment Notes, shall be distributed to the Liquidity Providers
         pari passu on the basis of the amount of such Liquidity Obligations
         owed to each Liquidity Provider;

         third, such amount as shall be required (A) if any Cash Collateral
         Account had been previously funded as provided in Section 3.6(f), to
         fund such Cash Collateral Account up to its Required Amount shall be
         deposited in such Cash Collateral Account, (B) if any Liquidity
         Facility shall become a Downgraded Facility or a Non- Extended
         Facility at a time when unreimbursed Interest Drawings under such
         Liquidity Facility have reduced the Available Amount thereunder to
         zero, to deposit into the related Cash Collateral Account an amount
         equal to such Cash Collateral Account's Required Amount shall be
         deposited in such Cash Collateral Account, and (C) if, with respect to
         any particular Liquidity Facility, neither subclause (A) nor subclause
         (B) of this clause "third" are applicable, to pay or reimburse the
         Liquidity Provider in respect of such Liquidity Facility in an amount
         equal to the amount of any unreimbursed Interest Drawings under such
         Liquidity Facility shall be distributed to such Liquidity Provider,
         pari passu on the basis of the amounts of all such deficiencies and/or
         unreimbursed Interest Drawings;

         fourth, if, with respect to any particular Liquidity Facility, any
         amounts are to be distributed pursuant to either subclause (A) or (B)
         of clause "third" above, then the Liquidity Provider with respect to
         such Liquidity Facility shall be paid the excess of (x) the aggregate
         outstanding amount of unreimbursed Advances (whether or not then due)
         under such Liquidity Facility over (y) the Required Amount for the
         relevant Class, pari passu on the basis of such amounts in respect of
         each Liquidity Provider;

         fifth, such amount as shall be required to pay in full Expected
         Distributions to the holders of Class A Certificates on such Special
         Distribution Date shall be distributed to the Class A Trustee;





                                       27
<PAGE>   32
         sixth, such amount as shall be required to pay in full Expected
         Distributions to the holders of Class B Certificates on such Special
         Distribution Date shall be distributed to the Class B Trustee;

         seventh, such amount as shall be required to pay in full Expected
         Distributions to the holders of Class C Certificates on such Special
         Distribution Date shall be distributed to the Class C Trustee; and

         eighth, the balance, if any, of such Special Payment shall be
         transferred to the Collection Account for distribution in accordance
         with Section 3.2 hereof.

For the purposes of this Section 2.4(b), clause (x) of the definition of
"Expected Distributions" shall be deemed to read as follows: "(x) accrued, due
and unpaid interest on such Certificates together with (without duplication)
accrued and unpaid interest on a portion of such Certificates equal to the
outstanding principal amount of Equipment Notes being redeemed, purchased or
prepaid (immediately prior to such redemption, purchase or prepayment)
(excluding interest, if any, payable with respect to the Deposits related to
such Trust)".

                 (ii)     Upon the occurrence of a Triggering Event (whether or
not continuing), the Subordination Agent shall make distributions pursuant to
this Section 2.4(b) of amounts on deposit in the Special Payments Account on
account of the redemption or purchase of all of the Equipment Notes issued
pursuant to an Indenture on the Special Distribution Date for such Special
Payment in accordance with Section 3.3 hereof.

                 (c)      Other Special Payments.  Except as provided in clause
(e) below, any amounts on deposit in the Special Payments Account other than in
respect of amounts to be distributed pursuant to Section 2.4(b) shall be
distributed on the Special Distribution Date therefor in accordance with
Article III hereof.

                 (d)      Investment of Amounts in Special Payments Account.
Any amounts on deposit in the Special Payments Account prior to the
distribution thereof pursuant to Section 2.4(b) or (c) shall be invested in
accordance with Section 2.2(b).  Investment Earnings on such investments shall
be distributed in accordance with Section 2.4(b) or (c), as the case may be.

                 (e)      Certain Payments.  The Subordination Agent will
distribute promptly upon receipt thereof (i) any indemnity payment received by
it from the Owner Participant, the Owner Trustee or Atlas in respect of any
Trustee, any Liquidity Provider, any Paying Agent, any Depositary or any Escrow
Agent (collectively, the "Payees") and (ii) any compensation (including,
without limitation, any fees payable to any Liquidity Provider under Section
2.03 of any Liquidity Facility) received by it from the Owner Participant, the
Owner Trustee or Atlas under any Operative Agreement in respect of any Payee,
directly to the Payee entitled thereto.

                 SECTION 2.5.  Designated Representatives.  (a)  With the

Liquidity Provider and each Trustee, and from time to time thereafter may

signatures of the officers of the Subordination Agent and the attorney-in-fact
and agents of the Subordination Agent (the "Subordination Agent

entitled to rely on the last Subordination Agent Incumbency Certificate
delivered to it hereunder.

                 (b)      With the delivery of this Agreement, each Trustee

Certificate") of a Responsible Officer of such Trustee certifying as to the
incumbency and specimen signatures of the officers of such Trustee and the
attorney-in-fact and agents of such Trustee (the "Trustee Representatives")
authorized to give Written Notices on behalf of such Trustee hereunder.  Until
the Subordination Agent receives a subsequent Trustee Incumbency Certificate,
it shall be entitled to rely on the last Trustee Incumbency Certificate
delivered to it hereunder.

                 (c)      With the delivery of this Agreement, each Liquidity
Provider shall furnish to the Subordination Agent, and from time to time
thereafter may furnish to the Subordination Agent, at such Liquidity Provider's
discretion, or upon the Subordination Agent's request (which request shall not
be made more than one time in any 12-month period), a certificate (an "LP
Incumbency Certificate") of any Responsible Officer of such Liquidity Provider
certifying as to the incumbency and specimen signatures of any officer,
attorney-in-fact, agent or other designated representative of such Liquidity
Provider (the "LP Representatives" and, together with the Subordination Agent

Representatives") authorized to give Written Notices on behalf of such
Liquidity Provider hereunder.  Until the Subordination Agent receives a
subsequent LP Incumbency Certificate, it shall be entitled to rely on the last
LP Incumbency Certificate delivered to it hereunder.

                 SECTION 2.6.  Controlling Party.  (a)  The Trustees and the
Liquidity Providers hereby agree that, with respect to any Indenture at any
given time, the Loan Trustee thereunder will be directed (i) in taking, or
refraining from taking, any action under such Indenture or with respect to the
Equipment Notes issued thereunder, so long as no Indenture Default has occurred
and is continuing thereunder, by the holders of at least a majority of the
outstanding principal amount of such Equipment Notes (provided that, for so





                                       29
<PAGE>   34
long as the Subordination Agent is the registered holder of the Equipment
Notes, the Subordination Agent shall act with respect to this clause (i) in
accordance with the directions of the Trustees (in the case of each such
Trustee, with respect to the Equipment Notes issued under such Indenture and
held as Trust Property of such Trust) constituting, in the aggregate,
directions with respect to such principal amount of Equipment Notes), and (ii)
after the occurrence and during the continuance of an Indenture Default
thereunder (which, in the case of an Indenture pertaining to a Leased Aircraft,
has not been cured by the applicable Owner Trustee or the applicable Owner
Participant, if applicable, pursuant to Section 4.03 of such Indenture), in
taking, or refraining from taking, any action under such Indenture or with
respect to such Equipment Notes, including exercising remedies thereunder
(including Accelerating the Equipment Notes issued thereunder or foreclosing
the Lien on the Aircraft securing such Equipment Notes), by the Controlling
Party.

                 (b)      The Person who shall be the "Controlling Party" with
respect to any Indenture shall be: (x) the Class A Trustee; (y) upon payment of
Final Distributions to the holders of Class A Certificates, the Class B
Trustee; and (z) upon payment of Final Distributions to the holders of Class B
Certificates, the Class C Trustee.  For purposes of giving effect to the
foregoing, the Trustees (other than the Controlling Party) irrevocably agree
(and the Certificateholders (other than the Certificateholders represented by
the Controlling Party) shall be deemed to agree by virtue of their purchase of
Certificates) that the Subordination Agent, as record holder of the Equipment
Notes, shall exercise its voting rights in respect of the Equipment Notes as
directed by the Controlling Party and any vote so exercised shall be binding
upon the Trustees and all Certificateholders.

                 The Subordination Agent shall give written notice to all of
the other parties to this Agreement promptly upon a change in the identity of
the Controlling Party.  Each of the parties hereto agrees that it shall not
exercise any of the rights of the Controlling Party at such time as it is not
the Controlling Party hereunder; provided, however, that nothing herein
contained shall prevent or prohibit any Non-Controlling Party from exercising
such rights as shall be specifically granted to such Non-Controlling Party
hereunder and under the other Operative Agreements.

                 (c)      Notwithstanding the foregoing, at any time after 18
months from the earlier to occur of (i) the date on which the entire Available
Amount under any Liquidity Facility shall have been drawn (for any reason other
than a Downgrade Drawing or a Non-Extension Drawing) and remain unreimbursed,
and (ii) the date on which all Equipment Notes shall have been Accelerated, the
Liquidity Providers with at least two-thirds of unreimbursed Liquidity
Obligations shall have the right to elect, by Written Notice to the
Subordination Agent and each of the Trustees, to become the Controlling Party
hereunder with respect to any Indenture at any time from and including the last
day of such 18-month period.

                 (d)      The exercise of remedies by the Controlling Party
under this Agreement shall be expressly limited by Section 4.1(a)(ii) hereof.

                 (e)      The Controlling Party shall not be entitled to
require or obligate any Non-Controlling Party to provide funds necessary to
exercise any right or remedy hereunder.

                 (c)      At such time as a Trustee or a Liquidity Provider
shall have received all amounts owing to it (and, in the case of a Trustee, the
Certificateholders for which it is acting) pursuant to Section 2.4, 3.2 or 3.3
hereof, as applicable, and, in the case of a Liquidity Provider, its commitment
under the related Liquidity Facility shall have terminated or expired, such
Person shall, by a Written Notice, so inform the Subordination Agent and each
other party to this Agreement.

                 (d)      As provided in Section 6.5 hereof, the Subordination

delivered in accordance with such paragraphs.

                 (e)      Any Written Notice delivered by a Trustee or a
Liquidity Provider, as applicable, pursuant to Section 3.1(a), 3.1(b) or 3.1(c)

such event, the Subordination Agent shall make distributions pursuant to
clauses "first" through "ninth" of Section 3.2 and clauses "first" through
"ninth" of Section 3.3 to the extent it shall have sufficient information to
enable it to make such distributions, and shall continue to hold any funds

receive all necessary information to enable it to distribute any funds so
withheld.

                 (g)      On such dates (but not more frequently than monthly)
as any Liquidity Provider or any Trustee shall request, but in any event
automatically at the end of each calendar quarter, the Subordination Agent
shall send to such party a written statement reflecting all amounts on deposit

in the case of any amount described in Section 2.4(c), on the Special
Distribution Date thereof) in the following order of priority and in accordance
with the information provided to the Subordination Agent pursuant to Section

         shall be deposited in such Sub-Account, (B) if any Liquidity Facility
         shall become a Downgraded Facility or a Non-Extended

         Liquidity Facility have reduced the Available Amount thereunder to
         zero, to deposit into the related Sub-Account of the related Cash
         Collateral Account an amount equal to such Sub-Account's Required
         Amount shall be deposited in such Cash Collateral Account, and (C) if,
         with respect to any particular Liquidity Facility, neither subclause
         (A) nor subclause (B) of this clause "third" is applicable, to pay or
         reimburse the Liquidity Provider in respect of such Liquidity Facility
         in an amount equal to the amount of all Liquidity Obligations then due

         to such Liquidity Facility shall be paid the excess of (x) the
         aggregate outstanding amount of unreimbursed Advances (whether or not
         then due) under such Liquidity Facility over (y) the Required Amount
         for the relevant Class, pari passu on the basis of such amounts in

         Expected Distributions to the holders of the Class C Certificates on
         such Distribution Date shall be distributed to the Class C Trustee;

                 eighth, such amount as shall be required to pay in full the
         aggregate unpaid amount of fees and expenses payable as of such
         Distribution Date to the Subordination Agent and each Trustee pursuant
         to the terms of this Agreement and the Trust Agreements, as the case
         may be, shall be distributed to the Subordination Agent and such
         Trustee; and

                 ninth, the balance, if any, of any such amount remaining
         thereafter shall be held in the Collection Account for later
         distribution in accordance with this Article III.

         incurred by it (to the extent not previously reimbursed) in the
         protection of, or the realization of the value of, the Equipment Notes
         or any Trust Indenture Estate, shall be applied by the Subordination
         Agent in reimbursement of such costs and expenses, (ii) each Trustee

         any, made by it to the Subordination Agent or any Trustee in respect
         of amounts described in clause (i) above, shall be distributed to such
         Liquidity Provider or to the applicable Trustee for the account of
         such Certificateholder, in each such case, pari passu on the basis of
         all amounts described in clauses (i) through (iii) above;

                 second, such amount remaining as shall be required to pay all
         accrued and unpaid Liquidity Expenses shall be distributed to each

         unpaid interest owed to each Liquidity Provider;

                 fourth, such amount remaining as shall be required (A) if any
         Cash Collateral Account had been previously funded as provided in
         Section 3.6(f), unless (i) a Performing Note Deficiency exists and a
         Liquidity Event of Default shall have occurred and be continuing with
         respect to the relevant Liquidity Facility or (ii) a Final Drawing
         shall have occurred with respect to such Liquidity Facility, to fund
         such Cash Collateral Account up to its Required Amount (less the
         amount of any repayments of Interest Drawings under such Liquidity
         Facility while subclause (A)(i) above is applicable) shall be
         deposited in such Cash Collateral Account, (B) if any Liquidity
         Facility shall become a Downgraded Facility or a Non-Extended Facility
         at a time when unreimbursed Interest Drawings under such Liquidity
         Facility have reduced the Available Amount thereunder to zero, unless
         (i) a Performing Note Deficiency exists and a Liquidity Event of
         Default shall have occurred and be continuing with respect to the
         relevant Liquidity Facility or (ii) a Final Drawing shall have
         occurred with respect to such Liquidity Facility, to deposit into the

         Collateral Account's Required Amount (less the amount of any
         repayments of Interest Drawings under such Liquidity Facility while
         subclause (B)(i) above is applicable) shall be deposited in such Cash
         Collateral Account, and (C) if, with respect to any particular
         Liquidity Facility, neither subclause (A) nor subclause (B) of this
         clause "fourth" are





                                       35
<PAGE>   40
         applicable, to pay in full the outstanding amount of all Liquidity
         Obligations then due under such Liquidity Facility (other than amounts
         payable pursuant to clause "second" or "third" of this Section 3.3)
         shall be distributed to such Liquidity Provider, pari passu on the
         basis of the amounts of all such deficiencies and/or unreimbursed
         Liquidity Obligations;

                 fifth, if, with respect to any particular Liquidity Facility,
         any amounts are to be distributed pursuant to either subclause (A) or
         (B) of clause "fourth" above, then the Liquidity Provider with respect
         to such Liquidity Facility shall be paid the excess of (x) the
         aggregate outstanding amount of unreimbursed Advances (whether or not
         then due) under such Liquidity Facility over (y) the Required Amount
         for the relevant Class (less the amount of any repayments of Interest
         Drawings under such Liquidity Facility while subclause (A)(i) or
         (B)(i), as the case may be, of clause "fourth" above is applicable),
         pari passu on the basis of such amounts in respect of each Liquidity
         Provider;

                 sixth, such amount as shall be required to reimburse or pay
         (i) the Subordination Agent for any Tax (other than Taxes imposed on
         compensation paid hereunder), expense, fee, charge or other loss
         incurred by or any other amount payable to the Subordination Agent in
         connection with the transactions contemplated hereby (to the extent
         not previously reimbursed), shall be applied by the Subordination
         Agent in reimbursement of such amount, (ii) each Trustee for any Tax
         (other than Taxes imposed on compensation paid under the applicable
         Trust Agreement), expense, fee, charge, loss or any other amount
         payable to such Trustee under the applicable Trust Agreements (to the
         extent not previously reimbursed), shall be distributed to such
         Trustee, and (iii) each Certificateholder for payments, if any, made
         by it pursuant to Section 5.2 hereof in respect of amounts described
         in clause (i) above, shall be distributed to the applicable Trustee
         for the account of such Certificateholder, in each such case, pari
         passu on the basis of all amounts described in clauses (i) through
         (iii) above;

                 seventh, such amount remaining as shall be required to pay in

         be distributed to the Class A Trustee;

                 eighth, such amount remaining as shall be required to pay in

<PAGE>   41
                 SECTION 3.4.  Other Payments.  (a)  Any payments received by
the Subordination Agent for which no provision as to the application thereof is
made in this Agreement shall be distributed by the Subordination Agent (i) in
the order of priority specified in Section 3.3 hereof and (ii) to the extent
received or realized at any time after the Final Distributions for each Class
of Certificates have been made, in the manner provided in clause "first" of
Section 3.3 hereof.

                 (b)      On any Interest Payment Date under each Liquidity
Facility which is not a Distribution Date, the Subordination Agent shall pay to
the Liquidity Provider under such Liquidity Facility from, and to the extent
of, amounts on deposit in the Collection Account, an amount equal to the amount
of interest then due and payable to such Liquidity Provider under such
Liquidity Facility.

                 (c)      Except as otherwise provided in Section 3.3 hereof,
if the Subordination Agent receives any Scheduled Payment after the Scheduled
Payment Date relating thereto, but prior to such payment becoming an Overdue
Scheduled Payment, then the Subordination Agent shall deposit such Scheduled
Payment in the Collection Account and promptly distribute such Scheduled
Payment in accordance with the priority of distributions set forth in Section
3.2 hereof; provided that, for the purposes of this Section 3.4(c) only, each
reference in clause "eighth" of Section 3.2 to "Distribution Date" shall be
deemed to mean the actual date of payment of such Scheduled Payment and each
reference in clause "fifth", "sixth" or "seventh" of Section 3.2 to
"Distribution Date" shall be deemed to refer to such Scheduled Payment Date.

                 SECTION 3.5.  Payments to the Trustees and the Liquidity
Providers.  Any amounts distributed hereunder to any Liquidity Provider shall
be paid to such Liquidity Provider by wire transfer of funds to the address
such Liquidity Provider shall provide to the Subordination Agent.  The
Subordination Agent shall provide a Written Notice of any such transfer to the
applicable Liquidity Provider, as the case may be, at the time of such
transfer.  Any amounts distributed hereunder by the Subordination Agent to any
Trustee which shall not be the same institution as the Subordination Agent
shall be paid to such Trustee by wire transfer funds at the address such
Trustee shall provide to the Subordination Agent.

                 SECTION 3.6.  Liquidity Facilities.  (a)  Interest Drawings.
If on any Distribution Date, after giving effect to the subordination
provisions of this Agreement, the Subordination Agent shall not have sufficient
funds for the payment of any amounts due and owing in respect of accrued
interest on the Class A Certificates, the Class B Certificates or the Class C
Certificates (at the Stated Interest Rate for such Class of Certificates),
then, prior to 12:00 noon (New York City time) on the Business Day following
such Distribution Date, the Subordination Agent shall request a drawing (each
such drawing, an "Interest Drawing") under each Liquidity Facility with respect
to such Class of Certificates in an amount equal to the lesser of (i) of an
amount sufficient to pay the amount of such accrued interest (at the Stated
Interest Rate for such Class of Certificates) and (ii) the Available Amount
under such





                                       37
<PAGE>   42
Liquidity Facility, and shall pay such amount to the Trustee with respect to
such Class of Certificates in payment of such accrued interest.

                 (b)      Application of Interest Drawings.  Notwithstanding
anything to the contrary contained in this Agreement, (i) all payments received
by the Subordination Agent in respect of an Interest Drawing under the Class A
Liquidity Facility and all amounts withdrawn by the Subordination Agent from
the Class A Cash Collateral Account, and payable in each case to the Class A
Certificateholders, shall be promptly distributed to the Class A Trustee, (ii)
all payments received by the Subordination Agent in respect of an Interest
Drawing under the Class B Liquidity Facility and all amounts withdrawn by the
Subordination Agent from the Class B Cash Collateral Account, and payable in
each case to the Class B Certificateholders, shall be promptly distributed to
the Class B Trustee and (iii) all payments received by the Subordination Agent
in respect of an Interest Drawing under the Class C Liquidity Facility and all
amounts withdrawn by the Subordination Agent from the Class C Cash Collateral
Account, and payable in each case to the Class C Certificateholders, shall be
promptly distributed to the Class C Trustee.

                 (c)      Downgrade Drawings.  If at any time (i) the
short-term unsecured debt rating of the Class A Liquidity Provider (with
respect to the Class A Liquidity Facility) or the Guarantor (with respect to
the MSCS Liquidity Facilities) issued by any Rating Agency is lower than the
applicable Threshold Rating or (ii) (with respect to any MSCS Liquidity
Facility) the related Guarantee Agreement ceases to be in full force and
effect, becomes invalid or unenforceable or the Guarantor denies its liability
thereunder (any such occurrence, a "Guarantee Event"), within 10 days (in the
case of the Class A Liquidity Facility) or 3 days (in the case of the MSCS
Liquidity Facilities) after receiving notice of such downgrading or Guarantee
Event, as the case may be (but not later than the expiration date of the
Liquidity Facility issued by the relevant Liquidity Provider (the "Downgraded
Facility")), such Liquidity Provider or Atlas may arrange for a Replacement
Liquidity Provider to issue and deliver a Replacement Liquidity Facility to the
Subordination Agent.  If a Downgraded Facility has not been replaced in
accordance with the terms of this paragraph, the Subordination Agent shall, on
such 10th or 3rd day, as the case may be, (or if such day is not a Business
Day, on the next succeeding Business Day) (or, if earlier, the expiration date
of such Downgraded Facility), request a drawing in accordance with and to the
extent permitted by such Downgraded Facility (such drawing, a "Downgrade
Drawing") of all available and undrawn amounts thereunder.  Amounts drawn
pursuant to a Downgrade Drawing shall be maintained and invested as provided in
Section 3.6(f) hereof.  The Liquidity Provider may also arrange for a
Replacement Liquidity Provider to issue and deliver a Replacement Liquidity
Facility at any time after such Downgrade Drawing so long as such Downgrade
Drawing has not been reimbursed in full to the Liquidity Provider.

                 (d)      Non-Extension Drawings.  If the Class A Liquidity
Facility is scheduled to expire on a date (the "Stated Expiration Date") prior
to the date that is 15 days after the Final Legal Distribution Date for the
Class A Certificates, then, no earlier than the 60th day and no later than the
40th day prior to the then Stated Expiration Date, the





                                       38
<PAGE>   43
Subordination Agent shall request that the Class A Liquidity Provider extend
the Stated Expiration Date for a period of 364 days after the Stated Expiration
Date (unless the obligations of the Class A Liquidity Provider thereunder are
earlier terminated in accordance with the Class A Liquidity Facility).  The
Class A Liquidity Provider shall advise the Borrower, no earlier than 40 days
and no later than 25 days prior to such Stated Expiration Date, whether, in its
sole discretion, it agrees to so extend the Stated Expiration Date.  If, on or
before such 25th day, the Class A Liquidity Facility shall not have been so
extended or replaced in accordance with Section 3.6(e), or if the Class A
Liquidity Provider fails irrevocably and unconditionally to advise the Borrower
on or before the 25th day prior to the Stated Expiration Date then in effect
that such Stated Expiration Date shall be so extended, the Subordination Agent
shall, on such 25th day (or as soon as possible thereafter), in accordance with
and to the extent permitted by the terms of the expiring Class A Liquidity
Facility (a "Non-Extended Facility"), request a drawing under such expiring
Class A Liquidity Facility (such drawing, a "Non-Extension Drawing") of all
available and undrawn amounts thereunder.  Amounts drawn pursuant to a
Non-Extension Drawing shall be maintained and invested in accordance with
Section 3.6(f) hereof.

                 (e)      Issuance of Replacement Liquidity Facility.  (i)  At
any time, Atlas may, at its option, with cause or without cause, arrange for a
Replacement Liquidity Facility to replace any Liquidity Facility for any Class
of Certificates (including any Replacement Liquidity Facility provided pursuant
to Section 3.6(e)(ii) hereof); provided, however, that neither ABN AMRO nor
MSCS shall be replaced by Atlas as a Liquidity Provider with respect to any
Class of Certificates prior to the fourth anniversary of the Closing Date
unless (A) there shall have become due to such Liquidity Provider, or such
Liquidity Provider shall have demanded, amounts pursuant to Section 3.01, 3.02
or 3.03 of any Liquidity Facility or pursuant to the Tax Letter and the
replacement of such Liquidity Provider would reduce or eliminate the obligation
to pay such amounts or Atlas determines in good faith that there is a
substantial likelihood that such Liquidity Provider will have the right to
claim any such amounts (unless such Liquidity Provider waives, in writing, any
right it may have to claim such amounts), which determination shall be set
forth in a certificate delivered by Atlas to such Liquidity Provider setting
forth the basis for such determination and accompanied by an opinion of outside
counsel selected by Atlas and reasonably acceptable to such Liquidity Provider
verifying the legal conclusions, if any, of such certificate relating to such
basis, provided that, in the case of any likely claim for such amounts based
upon any proposed, or proposed change in, law, rule, regulation,
interpretation, directive, requirement, request or administrative practice,
such opinion may assume the adoption or promulgation of such proposed matter,
(B) it shall become unlawful or impossible for such Liquidity Provider (or its
Lending Office) to maintain or fund its LIBOR Advances as described in Section
3.10 of any Liquidity Facility, (C) with respect to the Class A Liquidity
Facility, the short- term unsecured debt rating of such Liquidity Provider or,
with respect to the MSCS Liquidity Facilities, the short-term unsecured debt
rating of the Guarantor is downgraded by any Rating Agency and there is a
resulting downgrade in the rating by any Rating Agency of any related Class of

Facilities, as contemplated by the Letter Agreement dated as of January 23,
1998 between MSCS and Atlas, or (F) such Liquidity Provider shall have breached
any of its payment (including, without limitation, funding) obligations under
any Liquidity Facility.  If such Replacement Liquidity Facility is provided at
any time after a Downgrade Drawing or Non- Extension Drawing has been made, all
funds on deposit in the relevant Cash Collateral Account will be returned to
the Liquidity Provider being replaced.

                 (ii)     If any Liquidity Provider shall determine not to
         extend any of its Liquidity Facility in accordance with Section
         3.6(d), then such Liquidity Provider may, at its option, arrange for a
         Replacement Liquidity Facility to replace such Liquidity Facility
         during the period no earlier than 40 days and no later than 25 days
         prior to the then effective Stated Expiration Date of such Liquidity
         Facility.

                 (iii)    No Replacement Liquidity Facility arranged by Atlas
         or a Liquidity Provider in accordance with clause (i) or (ii) above,
         respectively, shall become effective and no such Replacement Liquidity
         Facility shall be deemed a "Liquidity Facility" under the Operative
         Agreements (in each case other than insofar as necessary to permit the
         repayment of amounts owed to the replaced Liquidity Provider), unless
         and until (A) each of the conditions referred to in clause (iv) below
         shall have been satisfied, (B) if such Replacement Liquidity Facility
         shall materially adversely affect the rights, remedies, interests or
         obligations of the Class A Certificateholders, the Class B
         Certificateholders or the Class C Certificateholders under any of the
         Operative Agreements, the applicable Trustee shall have consented, in
         writing, to the execution and issuance of such Replacement Liquidity
         Facility and (C) in the case of a Replacement Liquidity Facility
         arranged by a Liquidity Provider under Section 3.6(e)(ii), such
         Replacement Liquidity Facility is acceptable to Atlas.

                 (iv)     In connection with the issuance of each Replacement
         Liquidity Facility, the Subordination Agent shall (x) prior to the
         issuance of such Replacement Liquidity Facility, obtain written
         confirmation from each Rating Agency that such Replacement Liquidity
         Facility will not cause a reduction of any rating then in effect for
         any Class of Certificates by such Rating Agency (without regard to any
         downgrading of any rating of any Liquidity Provider being replaced
         pursuant to Section 3.6(c) hereof), (y) pay all Liquidity Obligations
         then owing to the replaced Liquidity Provider (which payment shall be
         made first from available funds in the Cash Collateral Account as
         described in clause (vii) of Section 3.6(f) hereof, and thereafter
         from any other available source, including, without limitation, a
         drawing under the Replacement Liquidity Facility) and (z) cause the
         issuer of the Replacement Liquidity Facility to deliver the
         Replacement Liquidity Facility to the Subordination Agent, together
         with a legal opinion opining that such Replacement Liquidity Facility
         is an enforceable obligation of such Replacement Liquidity Provider.

                 (v)      Upon satisfaction of the conditions set forth in
         clauses (iii) and (iv) of this Section 3.6(e), (w) the replaced
         Liquidity Facility shall terminate, (x) the

         Subordination Agent shall, if and to the extent so requested by Atlas
         or the Liquidity Provider being replaced, execute and deliver any
         certificate or other instrument required in order to terminate the
         replaced Liquidity Facility, shall surrender the replaced Liquidity
         Facility to the Liquidity Provider being replaced and shall execute
         and deliver the Replacement Liquidity Facility and any associated Fee
         Letter, (y) each of the parties hereto shall enter into any amendments
         to this Agreement necessary to give effect to (1) the replacement of
         the applicable Liquidity Provider with the applicable Replacement
         Liquidity Provider and (2) the replacement of the applicable Liquidity
         Facility with the applicable Replacement Liquidity Facility and (z)
         the applicable Replacement Liquidity Provider shall be deemed to be a
         Liquidity Provider with the rights and obligations of a Liquidity
         Provider hereunder and under the other Operative Agreements and such
         Replacement Liquidity Facility shall be deemed to be a Liquidity
         Facility hereunder and under the other Operative Agreements.

                 (f)      Cash Collateral Accounts; Withdrawals; Investments.
In the event the Subordination Agent shall draw all available amounts under the

applicable).  The Subordination Agent shall deliver a written statement to
Atlas and the Liquidity Provider one day prior to each Interest Payment Date

Collateral Accounts as of such date.  In addition, from and after the date
funds are so deposited, the Subordination Agent shall make withdrawals from
such account as follows:

         date), an amount equal to the sum of the Required Amount (with respect
         to the Class A Liquidity Facility) plus Investment Earnings on deposit
         in such Cash Collateral Account will be on deposit in the Class A Cash
         Collateral Account and shall first, pay such amount to the Class A

         date), an amount equal to the sum of the Required Amount (with respect
         to the Class C Liquidity Facility) plus Investment Earnings on deposit

         Collateral Account and shall first, pay such amount to the Class C
         Liquidity Provider until the Liquidity Obligations (with respect to
         the Class C Certificates) owing to such Liquidity Provider shall have
         been paid in full, and second, deposit any remaining amount in the
         Collection Account;

Cash Collateral Account pursuant to clause (i), (ii) or (iii) of Section 3.6(f)
hereof or (ii) such Liquidity Facility shall become a Downgraded Facility or a
Non-Extended Facility at a time when unreimbursed Interest Drawings under such
Liquidity Facility have reduced the Available Amount thereunder to zero, then
funds received by the Subordination Agent at any time other than (x) any time
when a Liquidity Event of Default shall have occurred and be continuing with
respect to such Liquidity Facility and a Performing Note Deficiency exists or
(y) any time after a Final Drawing shall have occurred with respect to such
Liquidity Facility shall be deposited in such Cash Collateral Account as and to
the extent provided in clause "third" of Section 2.4(b), clause "third" of

drawn pursuant to a Final Drawing shall be maintained and invested in
accordance with Section 3.6(f) hereof.

                 (j)      Relation to Subordination Provisions.  Interest
Drawings under the Liquidity Facilities and withdrawals from the Cash

                              EXERCISE OF REMEDIES

                 SECTION 4.1.  Directions from the Controlling Party.  (a)  (i)
Following the occurrence and during the continuation of an Indenture Default
under any Indenture, the Controlling Party shall direct the Subordination
Agent, which in turn shall direct the Loan Trustee under such Indenture, in the
exercise of remedies available to the holders of the Equipment Notes issued
pursuant to such Indenture, including, without limitation, the ability to vote
all such Equipment Notes in favor of Accelerating such Equipment Notes in
accordance with the provisions of such Indenture.  Subject to the Owner
Trustees' and the Owner Participants' rights, if any, set forth in the
Indentures with respect to Leased Aircraft to purchase the Equipment Notes and
the provisions of the next paragraph, if the Equipment Notes issued pursuant to
any Indenture have been Accelerated following an Indenture Default with respect
thereto, the Controlling Party may sell, assign, contract to sell or otherwise





                                       44
<PAGE>   49
dispose of and deliver all (but not less than all) of such Equipment Notes to
any Person at public or private sale, at any location at the option of the
Controlling Party, all upon such terms and conditions as it may reasonably deem
advisable in accordance with applicable law.

                 (ii)     Subject to the Owner Trustees' and the Owner
         Participants' rights, if any, set forth in the Indentures with respect
         to Leased Aircraft to purchase the Equipment Notes, and
         notwithstanding the foregoing, so long as any Certificates remain
         Outstanding, during the period ending on the date which is nine months
         after the earlier of (x) the Acceleration of the Equipment Notes
         issued pursuant to any Indenture or (y) the occurrence of a Atlas
         Bankruptcy Event, without the consent of each Trustee, (A) no Aircraft
         subject to the Lien of such Indenture or such Equipment Notes may be
         sold if the net proceeds from such sale would be less than the Minimum
         Sale Price for such Aircraft or such Equipment Notes, and (B) with
         respect to any Leased Aircraft, the amount and payment dates of
         rentals payable by Atlas under the Lease for such Aircraft may not be
         adjusted, if, as a result of such adjustment, the discounted present
         value of all such rentals would be less than 75% of the discounted
         present value of the rentals payable by Atlas under such Lease before
         giving effect to such adjustment, in each case, using the weighted
         average interest rate of the Equipment Notes issued pursuant to such
         Indenture as the discount rate.

                 (iii)    At the request of the Controlling Party, the
         Subordination Agent may from time to time during the continuance of an
         Indenture Default (and before the occurrence of a Triggering Event)
         commission LTV Appraisals with respect to the Aircraft subject to such
         Indenture.

                 (iv)     After a Triggering Event occurs and any Equipment
         Note becomes a Non-Performing Equipment Note, the Subordination Agent
         shall obtain Appraisals with respect to all of the Aircraft (the "LTV
         Appraisals") as soon as practicable and additional LTV Appraisals on
         or prior to each anniversary of the date of such initial LTV
         Appraisals; provided that if the Controlling Party reasonably objects
         to the appraised value of the Aircraft shown in such LTV Appraisals,
         the Controlling Party shall have the right to obtain or cause to be
         obtained substitute any LTV Appraisals (including any LTV Appraisals
         based upon physical inspection of the Aircraft).

                 (b)      The Controlling Party shall take such actions as it
may reasonably deem most effectual to complete the sale or other disposition of
such Aircraft or Equipment Notes.  In addition, in lieu of any sale,
assignment, contract to sell or other disposition, the Controlling Party may
maintain possession of such Equipment Notes and continue to apply monies
received in respect of such Equipment Notes in accordance with Article III
hereof.  In addition, in lieu of such sale, assignment, contract to sell or
other disposition, or in lieu of such maintenance of possession, the
Controlling Party may, subject to the terms and conditions of the related
Indenture, instruct the Loan Trustee under such Indenture to foreclose on the
Lien on the related Aircraft.

                 SECTION 4.2.  Remedies Cumulative.  Each and every right,
power and remedy given to the Trustees, the Liquidity Providers, the
Controlling Party or the Subordination Agent specifically or otherwise in this
Agreement shall be cumulative and shall be in addition to every other right,
power and remedy herein specifically given or now or hereafter existing at law,
in equity or by statute, and each and every right, power and remedy whether
specifically herein given or otherwise existing may, subject always to the
terms and conditions hereof, be exercised from time to time and as often and in
such order as may be deemed expedient by any Trustee, any Liquidity Provider,
the Controlling Party or the Subordination Agent, as appropriate, and the
exercise or the beginning of the exercise of any power or remedy shall not be
construed to be a waiver of the right to exercise at the same time or
thereafter any other right, power or remedy.  No delay or omission by any
Trustee, any Liquidity Provider, the Controlling Party or the Subordination
Agent in the exercise of any right, remedy or power or in the pursuit of any
remedy shall impair any such right, power or remedy or be construed to be a
waiver of any default or to be an acquiescence therein.

                 SECTION 4.3.  Discontinuance of Proceedings.  In case any
party to this Agreement (including the Controlling Party in such capacity)
shall have instituted any Proceeding to enforce any right, power or remedy
under this Agreement by foreclosure, entry or otherwise, and such Proceeding
shall have been discontinued or abandoned for any reason or shall have been
determined adversely to the Person instituting such Proceeding, then and in
every such case each such party shall, subject to any determination in such
Proceeding, be restored to its former position and rights hereunder, and all
rights, remedies and powers of such party shall continue as if no such
Proceeding had been instituted.

                 SECTION 4.4.  Right of Certificateholders to Receive Payments
Not to Be Impaired.  Anything in this Agreement to the contrary notwithstanding
but subject to each Trust Agreement, the right of any Certificateholder or any
Liquidity Provider, respectively, to receive payments hereunder (including
without limitation pursuant to Section 2.4, 3.2 or 3.3 hereof) when due, or to
institute suit for the enforcement of any such payment on or after the
applicable Distribution Date, shall not be impaired or affected without the
consent of such Certificateholder or such Liquidity Provider, respectively.

                 SECTION 4.5.  Undertaking for Costs.  In any Proceeding for
the enforcement of any right or remedy under this Agreement or in any
Proceeding against any Controlling Party or the Subordination Agent for any
action taken or omitted by it as Controlling Party or Subordination Agent, as
the case may be, 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 and expenses, 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.  The provisions of this Section do not apply to a suit
instituted by the Subordination Agent, a Liquidity Provider or a Trustee or a
suit by Certificateholders holding more than 10% of the original principal
amount of any Class of Certificates.

the Subordination Agent shall have been indemnified (to the extent and in the
manner reasonably satisfactory to the Subordination Agent) against any
liability, cost or expense (including counsel fees and expenses) which may be
incurred in connection therewith.  The Subordination Agent shall not be under
any obligation to take any action under this Agreement and nothing contained in
this Agreement shall require the Subordination Agent 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.  The Subordination Agent shall not be required to take any action under
Section 5.1 (other than the first sentence thereof) or Article IV hereof, nor
shall any other provision of this Agreement be deemed to impose a duty on the
Subordination Agent to take any action, if the Subordination Agent shall have
been advised by counsel that such action is contrary to the terms hereof or is
otherwise contrary to law.

                 SECTION 5.3.  No Duties Except as Specified in Intercreditor
Agreement. The Subordination Agent shall not have any duty or obligation to
take or refrain from taking





                                       47
<PAGE>   52
any action under, or in connection with, this Agreement, except as expressly
provided by the terms of this Agreement; and no implied duties or obligations
shall be read into this Agreement against the Subordination Agent.  The
Subordination Agent agrees that it will, in its individual capacity and at its
own cost and expense (but without any right of indemnity in respect of any such
cost or expense under Section 7.1 hereof) promptly take such action as may be
necessary to duly discharge all Liens on any of the Trust Accounts or any
monies deposited therein which result from claims against it in its individual
capacity not related to its activities hereunder or any other Operative
Agreement.

                 SECTION 5.4.  Notice from the Liquidity Providers and
Trustees.  If any Liquidity Provider or Trustee has notice of an Indenture
Default or a Triggering Event, such Person shall promptly give notice thereof
to all other Liquidity Providers and Trustees and to the Subordination Agent,
provided, however, that no such Person shall have any liability hereunder as a
result of its failure to deliver any such notice.


                                   ARTICLE VI

                            THE SUBORDINATION AGENT

                 SECTION 6.1.  Authorization; Acceptance of Trusts and Duties.
Each of the Class A Trustee, the Class B Trustee and the Class C Trustee hereby
designates and appoints the Subordination Agent as the agent and trustee of
such Trustee under the applicable Liquidity Facility and authorizes the
Subordination Agent to enter into the applicable Liquidity Facility as agent
and trustee for such Trustee.   Each of the Liquidity Providers and the
Trustees hereby designates and appoints the Subordination Agent as the
Subordination Agent under this Agreement. WTC hereby accepts the duties hereby
created and applicable to it as the Subordination Agent and agrees to perform
the same but only upon the terms of this Agreement and agrees to receive and
disburse all monies received by it in accordance with the terms hereof.  The
Subordination Agent shall not be answerable or accountable under any
circumstances, except (a) for its own willful misconduct or gross negligence
(or ordinary negligence in the handling of funds), (b) as provided in Section
2.2 hereof and (c) for liabilities that may result from the material inaccuracy
of any representation or warranty of the Subordination Agent made in its
individual capacity in any Operative Agreement.  The Subordination Agent shall
not be liable for any error of judgment made in good faith by a Responsible
Officer of the Subordination Agent, unless it is proved that the Subordination
Agent was negligent in ascertaining the pertinent facts.

                 SECTION 6.2.  Absence of Duties.  The Subordination Agent
shall have no duty to see to any recording or filing of this Agreement or any
other document, or to see to the maintenance of any such recording or filing.

                 SECTION 6.3.  No Representations or Warranties as to
Documents.  The Subordination Agent in its individual capacity does not make
nor shall be deemed to have





                                       48
<PAGE>   53
made any representation or warranty as to the validity, legality or
enforceability of this Agreement or any other Operative Agreement or as to the
correctness of any statement contained in any thereof, except for the
representations and warranties of the Subordination Agent, made in its
individual capacity, under any Operative Agreement to which it is a party.  The
Certificateholders, the Trustees and the Liquidity Providers make no
representation or warranty hereunder whatsoever.

                 SECTION 6.4.  No Segregation of Monies; No Interest.  Any
monies paid to or retained by the Subordination Agent pursuant to any provision
hereof and not then required to be distributed to any Trustee or any Liquidity
Provider as provided in Articles II and III hereof or deposited into one or
more Trust Accounts need not be segregated in any manner except to the extent
required by such Articles II and III and by law, and the Subordination Agent
shall not (except as otherwise provided in Section 2.2 hereof) be liable for
any interest thereon; provided, however, that any payments received or applied
hereunder by the Subordination Agent shall be accounted for by the
Subordination Agent so that any portion thereof paid or applied pursuant hereto
shall be identifiable as to the source thereof.

                 SECTION 6.5.  Reliance; Agents; Advice of Counsel.  The
Subordination Agent shall not incur liability to anyone in acting upon any
signature, instrument, notice, resolution, request, consent, order,
certificate, report, opinion, bond or other document or paper believed by it to
be genuine and believed by it to be signed by the proper party or parties.  As
to the Pool Balance of any Trust as of any date, the Subordination Agent may
for all purposes hereof rely on a certificate signed by any Responsible Officer
of the applicable Trustee, and such certificate shall constitute full
protection to the Subordination Agent for any action taken or omitted to be
taken by it in good faith in reliance thereon.  As to any fact or matter
relating to the Liquidity Providers or the Trustees the manner of ascertainment
of which is not specifically described herein, the Subordination Agent may for
all purposes hereof rely on a certificate, signed by any Responsible Officer of
the applicable Liquidity Provider or Trustee, as the case may be, as to such
fact or matter, and such certificate shall constitute full protection to the
Subordination Agent for any action taken or omitted to be taken by it in good
faith in reliance thereon.  The Subordination Agent shall assume, and shall be
fully protected in assuming, that each of the Liquidity Providers and each of
the Trustees are authorized to enter into this Agreement and to take all action
to be taken by them pursuant to the provisions hereof, and shall not inquire
into the authorization of each of the Liquidity Providers and each of the
Trustees with respect thereto.  In the administration of the trusts hereunder,
the Subordination Agent may execute any of the trusts or powers hereof and
perform its powers and duties hereunder directly or through agents or attorneys
and may consult with counsel, accountants and other skilled persons to be
selected and retained by it, and the Subordination Agent shall not be liable
for the acts or omissions of any agent appointed with due care or for anything
done, suffered or omitted in good faith by it in accordance with the advice or
written opinion of any such counsel, accountants or other skilled persons.

                 SECTION 6.6.  Capacity in Which Acting.  The Subordination
Agent acts hereunder solely as agent and trustee herein and not in its
individual capacity, except as otherwise expressly provided in the Operative
Agreements.

                 SECTION 6.7.  Compensation.  The Subordination Agent shall be
entitled to reasonable compensation, including expenses and disbursements, for
all services rendered hereunder and shall have a priority claim to the extent
set forth in Article III hereof on all monies collected hereunder for the
payment of such compensation, to the extent that such compensation shall not be
paid by others.  The Subordination Agent agrees that it shall have no right
against any Trustee or Liquidity Provider for any fee as compensation for its
services as agent under this Agreement.  The provisions of this Section 6.7
shall survive the termination of this Agreement.

                 SECTION 6.8.  May Become Certificateholder.  The institution
acting as Subordination Agent hereunder may become a Certificateholder and have
all rights and benefits of a Certificateholder to the same extent as if it were
not the institution acting as the Subordination Agent.

                 SECTION 6.9.  Subordination Agent Required; Eligibility. There
shall at all times be a Subordination Agent hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America or of any State or the District of Columbia having a combined capital
and surplus of at least $100,000,000 (or the obligations of which, whether now
in existence or hereafter incurred, are fully and unconditionally guaranteed by
a corporation organized and doing business under the laws of the United States
of America, any State thereof or of the District of Columbia and having a
combined capital and surplus of at least $100,000,000), if there is such an
institution willing and able to perform the duties of the Subordination Agent
hereunder upon reasonable or customary terms.  Such corporation shall be a
citizen of the United States and shall be authorized under the laws of the
United States or any State thereof or of the District of Columbia to exercise
corporate trust powers and shall be subject to supervision or examination by
federal, state or District of Columbia authorities.  If such corporation
publishes reports of condition at least annually, pursuant to law or to the
requirements of any of the aforesaid supervising or examining authorities,
then, for the purposes of this Section 6.9, the combined capital and surplus of
such corporation shall be deemed to be its combined capital and surplus as set
forth in its most recent report of condition so published.

                 In case at any time the Subordination Agent shall cease to be
eligible in accordance with the provisions of this Section, the Subordination
Agent shall resign immediately in the manner and with the effect specified in
Section 8.1.

                 SECTION 6.10.  Money to Be Held in Trust.  All Equipment
Notes, monies and other property deposited with or held by the Subordination
Agent pursuant to this Agreement shall be held in trust for the benefit of the
parties entitled to such Equipment Notes, monies and other property.  All such
Equipment Notes, monies or other property





                                       50
<PAGE>   55
shall be held in the Trust Department of the institution acting as
Subordination Agent hereunder.


                                  ARTICLE VII

                     INDEMNIFICATION OF SUBORDINATION AGENT

                 SECTION 7.1.  Scope of Indemnification.  The Subordination
Agent shall be indemnified hereunder to the extent and in the manner described
in Section 9.1 of the Participation Agreements and Section 7 of the Note
Purchase Agreement.  The indemnities contained in such Sections of such
agreements shall survive the termination of this Agreement.


                                  ARTICLE VIII

                         SUCCESSOR SUBORDINATION AGENT

                 SECTION 8.1.  Replacement of Subordination Agent; Appointment
of Successor.  The Subordination Agent may resign at any time by so notifying
the Trustees and the Liquidity Providers.  The Controlling Party may remove the
Subordination Agent for cause by so notifying the Subordination Agent and may
appoint a successor Subordination Agent.  The Controlling Party shall remove
the Subordination Agent if:

                 (1)      the Subordination Agent fails to comply with Section
                          6.9 hereof;

                 (2)      the Subordination Agent is adjudged bankrupt or
                          insolvent;

                 (3)      a receiver or other public officer takes charge of
                          the Subordination Agent or its property; or

                 (4)      the Subordination Agent otherwise becomes incapable
                          of acting.

                 If the Subordination Agent resigns or is removed or if a
vacancy exists in the office of Subordination Agent for any reason (the
Subordination Agent in such event being referred to herein as the retiring
Subordination Agent), the Controlling Party shall promptly appoint a successor
Subordination Agent.

                 A successor Subordination Agent shall deliver (x) a written
acceptance of its appointment as Subordination Agent hereunder to the retiring
Subordination Agent and (y) a written assumption of its obligations hereunder
and under each Liquidity Facility to each party hereto, upon which the
resignation or removal of the retiring Subordination Agent shall become
effective, and the successor Subordination Agent shall have all the rights,
powers





                                       51
<PAGE>   56
and duties of the Subordination Agent under this Agreement.  The successor
Subordination Agent shall mail a notice of its succession to the Liquidity
Providers and the Trustees.  The retiring Subordination Agent shall promptly
transfer its rights under each of the Liquidity Facilities and all of the
property held by it as Subordination Agent to the successor Subordination
Agent.

                 If a successor Subordination Agent does not take office within
60 days after the retiring Subordination Agent resigns or is removed, the
retiring Subordination Agent or one or more of the Trustees may petition any
court of competent jurisdiction for the appointment of a successor
Subordination Agent.

                 If the Subordination Agent fails to comply with Section 6.9
hereof (to the extent applicable), one or more of the Trustees or one or more
of the Liquidity Providers may petition any court of competent jurisdiction for
the removal of the Subordination Agent and the appointment of a successor
Subordination Agent.

                 Notwithstanding the foregoing, no resignation or removal of
the Subordination Agent shall be effective unless and until a successor has
been appointed.  No appointment of a successor Subordination Agent shall be
effective unless and until the Rating Agencies shall have delivered a Ratings
Confirmation.


                                   ARTICLE IX

                           SUPPLEMENTS AND AMENDMENTS

                 SECTION 9.1.  Amendments, Waivers, etc.  (a)  This Agreement
may not be supplemented, amended or modified without the consent of each
Trustee (acting, except in the case of any amendment pursuant to Section
3.6(e)(v)(y) hereof, with the consent of holders of Certificates of the related
Class evidencing interests in the related Trust aggregating not less than a
majority in interest in such Trust or as otherwise authorized pursuant to the
relevant Trust Agreement), the Subordination Agent and each Liquidity Provider;
provided, however, that this Agreement may be supplemented, amended or modified
without the consent of (x) any Trustee if such supplement, amendment or
modification (i) is in accordance with Section 9.1(c) hereof or (ii) cures an
ambiguity or inconsistency or does not materially adversely affect such Trustee
or the holders of the related Class of Certificates and (y) any Liquidity
Provider if such supplement, amendment or modification is in accordance with
Section 9.1(c) hereof; provided further, however, that, if such supplement,
amendment or modification (A) would (x) directly or indirectly modify or
supersede, or otherwise conflict with, Section 2.2(b), Section 3.6(e), Section
3.6(f)(other than the last sentence thereof), or the second sentence of Section
10.6 (collectively, together with this proviso and Section 9.1(c), the "Atlas
Provisions") or (y) otherwise adversely affect the interests of a potential
Replacement Liquidity Provider or of Atlas with respect to its ability to
replace any Liquidity Facility or with respect to its payment obligations under
any





                                       52
<PAGE>   57
Financing Agreement, Leased or Owned Aircraft Indenture or (B) is made pursuant
to Section 9.1(c), then such supplement, amendment or modification shall not be
effective without the additional written consent of Atlas.  Notwithstanding the
foregoing, without the consent of each Certificateholder and the Liquidity
Provider with respect to the applicable Class of Certificates, no supplement,
amendment or modification of this Agreement may (i) reduce the percentage of
the interest in the related Trust evidenced by the Certificates issued by such
Trust necessary to consent to modify or amend any provision of this Agreement
or to waive compliance therewith or (ii), except as provided in Section 9.1(c),
modify Section 2.4, 3.2 or 3.3 hereof, relating to the distribution of monies
received by the Subordination Agent hereunder from the Equipment Notes or
pursuant to the Liquidity Facilities.  Nothing contained in this Section shall
require the consent of a Trustee at any time following the payment of Final
Distributions with respect to the related Class of Certificates.

                 (b)      In the event that the Subordination Agent, as the
registered holder of any Equipment Notes, receives a request for its consent to
any amendment, modification, consent or waiver under such Equipment Notes, the
Indenture pursuant to which such Equipment Notes were issued, or the related
Lease, Participation Agreement or other related document, (i) if no Indenture
Default shall have occurred and be continuing with respect to such Indenture,
the Subordination Agent shall request directions with respect to each Series of
such Equipment Notes from the Trustee of the Trust which holds such Equipment
Notes and shall vote or consent in accordance with the directions of such
Trustee and (ii) if any Indenture Default (which, in the case of any Indenture
pertaining to a Leased Aircraft, has not been cured by the applicable Owner
Trustee or the applicable Owner Participant, if applicable, pursuant to Section
4.03 of such Indenture) shall have occurred and be continuing with respect to
such Indenture, the Subordination Agent will exercise its voting rights as
directed by the Controlling Party, subject to Sections 4.1 and 4.4 hereof;
provided that no such amendment, modification or waiver shall, without the
consent of each Liquidity Provider, reduce the amount of rent, supplemental
rent or stipulated loss values payable by Atlas under any Lease or reduce the
amount of principal or interest payable by Atlas under any Equipment Note
issued under any Indenture in respect of an Owned Aircraft.

                 (c)      If with respect to any Owned Aircraft Atlas issues
Class D Certificates, this Agreement shall be amended by written agreement of
Atlas and the Subordination Agent to provide for the subordination of such
Class D Certificates to the Class A Certificates, the Class B Certificates and
the Class C Certificates substantially in the same manner as the Class C
Certificates are subordinated hereunder to the Class B and Class A
Certificates.  No such amendment shall materially adversely affect any Trustee.
The amendment to this Agreement to give effect to the issuance of any Class D
Certificates shall include, without limitation:

                 (i)      the trustee of the Class D Trust shall be added as a
         party to this Agreement;





                                       53

                 (ii)     the definitions of "Cash Collateral Account,"
         "Certificate," "Class," "Equipment Notes," "Final Legal Distribution
         Date," "Liquidity Facilities," "Liquidity Provider," "LTV Ratio,"
         "Stated Interest Rate," "Trust," "Trust Agreement" and "Controlling
         Party" shall be revised, as appropriate, to reflect the issuance of
         the Class D Certificates (and the subordination thereof); and

                 (iii)    provisions of this Agreement governing payments with
         respect to Certificates and related notices, including, without
         limitation, Sections 2.4, 3.1, 3.2, 3.3 and 3.6(e), shall be revised
         to provide for distributions on the Class D Certificates after payment
         of all relevant distributions on Class C Certificates.

                 SECTION 9.2.  Subordination Agent Protected.  If, in the
reasonable opinion of the institution acting as the Subordination Agent
hereunder, any document required to be executed pursuant to the terms of
Section 9.1 affects any right, duty, immunity or indemnity with respect to it
under this Agreement or any Liquidity Facility, the Subordination Agent may in
its discretion decline to execute such document.

                 SECTION 9.3.  Effect of Supplemental Agreements.  Upon the
execution of any amendment, consent or supplement hereto pursuant to the
provisions hereof, this Agreement shall be and be deemed to be and shall be
modified and amended in accordance therewith and the respective rights,
limitations of rights, obligations, duties and immunities under this Agreement
of the parties hereto and beneficiaries hereof shall thereafter be determined,
exercised and enforced hereunder subject in all respects to such modifications
and amendments, and all the terms and conditions of any such supplemental
agreement shall be and be deemed to be and shall be part of the terms and
conditions of this Agreement for any and all purposes.  In executing or
accepting any supplemental agreement permitted by this Article IX, the
Subordination Agent shall be entitled to receive, and shall be fully protected
in relying upon, an opinion of counsel stating that the execution of such
supplemental agreement is authorized or permitted by this Agreement.

                 SECTION 9.4.  Notice to Rating Agencies.  Promptly following
its receipt of each amendment, consent, modification, supplement or waiver
contemplated by this Article IX, the Subordination Agent shall send a copy
thereof to each Rating Agency.

Provisions shall inure to the benefit of Atlas and its successors and assigns,
and (without limitation of the foregoing) Atlas is hereby constituted, and
agreed to be, an express third party beneficiary of the Atlas Provisions.  Upon
the occurrence of the Transfers contemplated by the Assignment and Assumption
Agreements, the Trustee of each Class shall (without any further act) be deemed
to have transferred all of its rights, title and interest in and to this
Agreement to the trustee of the Successor Trust of the same Class and,
thereafter, the trustee of each Successor Trust shall be deemed to be the
"Trustee" of such Successor Trust with the rights and obligations of a
"Trustee" hereunder and under the other Operative Agreements and each reference
to a Trust of any Class herein shall be deemed a reference to the Successor
Trust of such Class.

                 SECTION 10.7.  Headings.  The headings of the various Articles
and Sections herein and in the table of contents hereto are for convenience of
reference only and shall not define or limit any of the terms or provisions
hereof.

                 SECTION 10.8.  Counterpart Form.  This Agreement may be
executed by the parties hereto in separate counterparts, each of which when so
executed and delivered shall be an original, but all such counterparts shall
together constitute but one and the same agreement.

                 SECTION 10.9.  Subordination.  (a)  As between the Liquidity
Providers, on the one hand, and the Trustees and the Certificateholders, on the
other hand, this Agreement shall be a subordination agreement for purposes of
Section 510 of the United States Bankruptcy Code, as amended from time to time.

                 (b)      Notwithstanding the provisions of this Agreement, if
prior to the payment in full to the Liquidity Providers of all Liquidity
Obligations then due and payable, any party hereto shall have received any
payment or distribution in respect of Equipment Notes or any other amount under
the Indentures or other Operative Agreements which, had the subordination
provisions of this Agreement been properly applied to such payment,
distribution or other amount, would not have been distributed to such Person,
then such payment, distribution or other amount shall be received and held in
trust by such Person and paid over or delivered to the Subordination Agent for
application as provided herein.

                 (c)      If any Trustee, any Liquidity Provider or the
Subordination Agent receives any payment in respect of any obligations owing
hereunder (or, in the case of the Liquidity Providers, in respect of the
Liquidity Obligations), which is subsequently invalidated, declared
preferential, set aside and/or required to be repaid to a trustee, receiver or
other party, then, to the extent of such payment, such obligations (or, in the
case of the Liquidity Providers, such Liquidity Obligations) intended to be
satisfied shall be revived and continue in full force and effect as if such
payment had not been received.

                 (d)      The Trustees (on behalf of themselves and the holders
of Certificates), the Liquidity Providers and the Subordination Agent confirm
that the payment priorities





                                       57
<PAGE>   62
specified in Sections 2.4, 3.2 and 3.3 shall apply in all circumstances,
notwithstanding the fact that the obligations owed to the Trustees and the
holders of Certificates are secured by certain assets and the Liquidity
Obligations may not be so secured.  The Trustees expressly agree (on behalf of
themselves and the holders of Certificates) not to assert priority over the
holders of Liquidity Obligations due to their status as secured creditors in
any bankruptcy, insolvency or other legal proceeding.

                 (e)      Each of the Trustees (on behalf of themselves and the
holders of Certificates), the Liquidity Providers and the Subordination Agent
may take any of the following actions without impairing its rights under this
Agreement:

                 (i)      obtain a Lien on any property to secure any amounts
         owing to it hereunder, including, in the case of the Liquidity
         Providers, the Liquidity Obligations,

                 (ii)     obtain the primary or secondary obligation of any
         other obligor with respect to any amounts owing to it hereunder,
         including, in the case of the Liquidity Providers, any of the
         Liquidity Obligations,

                 (iii)    renew, extend, increase, alter or exchange any
         amounts owing to it hereunder, including, in the case of the Liquidity
         Providers, any of the Liquidity Obligations, or release or compromise
         any obligation of any obligor with respect thereto,

                 (iv)     refrain from exercising any right or remedy, or delay
         in exercising such right or remedy, which it may have, or

                 (v)      take any other action which might discharge a
         subordinated party or a surety under applicable law;

provided, however, that the taking of any such actions by any of the Trustees,
the Liquidity Providers or the Subordination Agent shall not prejudice the
rights or adversely affect the obligations of any other party under this
Agreement.

                 SECTION 10.10.  Governing Law.  THIS AGREEMENT SHALL IN ALL
RESPECTS BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE
OF NEW YORK, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE.

                 SECTION 10.11.  Submission to Jurisdiction; Waiver of Jury
Trial; Waiver of Immunity.  (a)  Each of the parties hereto hereby irrevocably
and unconditionally:

                 (i)      submits for itself and its property in any legal
         action or proceeding relating to this Agreement or any other Operative
         Agreement, or for recognition and





                                       58

         enforcement of any judgment in respect hereof or thereof, to the
         nonexclusive general jurisdiction of the courts of the State of New
         York, the courts of the United States of America for the Southern
         District of New York, and the appellate courts from any thereof;

                 (ii)     consents that any such action or proceeding may be
         brought in such courts, and waives any objection that it may now or
         hereafter have to the venue of any such action or proceeding in any
         such court or that such action or proceeding was brought in an
         inconvenient court and agrees not to plead or claim the same;

                 (iii)    agrees that service of process in any such action or
         proceeding may be effected by mailing a copy thereof by registered or
         certified mail (or any substantially similar form and mail), postage
         prepaid, to each party hereto at its address set forth in Section 10.3
         hereof, or at such other address of which the other parties shall have
         been notified pursuant thereto; and

                 (iv)     agrees that nothing herein shall affect the right to
         effect service of process in any other manner permitted by law or
         shall limit the right to sue in any other jurisdiction.

                 (b)      EACH OF THE PARTIES HERETO HEREBY AGREES TO WAIVE ITS
RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR
ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM RELATING TO THE
SUBJECT MATTER OF THIS AGREEMENT AND THE RELATIONSHIP THAT IS BEING
ESTABLISHED, including, without limitation, contract claims, tort claims,
breach of duty claims and all other common law and statutory claims.  Each of
the parties warrants and represents that it has reviewed this waiver with its
legal counsel, and that it knowingly and voluntarily waives its jury trial
rights following consultation with such legal counsel.  THIS WAIVER IS
IRREVOCABLE, AND CANNOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THIS
WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR
MODIFICATIONS TO THIS AGREEMENT.

                 (c)      The Class A Liquidity Provider hereby waives any
immunity it may have from the jurisdiction of the courts of the United States
of America or of any State and waives any immunity any of its properties
located in the United States of America may have from attachment or execution
upon a judgment entered by any such court under the United States Foreign
Sovereign Immunities Act of 1976 or any similar successor legislation.

                  (c) Upon receipt of a Delivery Notice, the Pass Through
Trustees shall, and shall cause the Subordination Agent to, enter into and
perform their obligations under the Participation Agreement specified in such
Delivery Notice, provided that such Participation Agreement and the other Lease
Financing Agreements or Owner Financing Agreements to be entered into pursuant
to such Participation Agreement shall be in the forms thereof annexed hereto in
all material respects with such changes therein as shall have been requested by
the related Owner Participant (in the case of Lease Financing Agreements) or by
the placement agents of the Series D Equipment Notes, if

any (in the case of the Owner Financing Agreements), agreed to by the Company
and, if modified in any material respect (other than modifications affecting
only the Owner Participants and modifications that do not materially and
adversely affect the Certificateholders), as to which Rating Agency
Confirmation shall have been obtained from each Rating Agency by the Company
(to be delivered by the Company to the applicable Pass Through Trustee on or
before the relevant Delivery Date, it being understood that if Rating Agency
Confirmation shall have been received with respect to any Financing Agreements
and such Financing Agreements are utilized for subsequent Aircraft (or
Substitute Aircraft) without material modifications, no additional Rating
Agency Confirmation shall be required); provided, however, that the relevant
Financing Agreements as executed and delivered shall not vary the Mandatory
Economic Terms and shall contain the Mandatory Document Terms. Notwithstanding
the foregoing, if any Financing Agreement annexed hereto shall not have been
reviewed by either Rating Agency prior to the Issuance Date, then, prior to the
use thereof in connection with the financing of any Aircraft hereunder, the
Company shall obtain from each Rating Agency a confirmation that the use of
such Financing Documents would not result in (x) a reduction of the rating for
any Class of Certificates below the then current rating for such Class of
Certificates or (y) a withdrawal or suspension of the rating of any Class of
Certificates. With respect to each Aircraft, the Company shall cause Wilmington
Trust Company (or such other person that meets the eligibility requirements to
act as loan trustee under the Leased Aircraft Indenture or Owned Aircraft
Indenture) to execute as Loan Trustee the Financing Agreements relating to such
Aircraft to which such Loan Trustee is intended to be a party, and shall
concurrently therewith execute such Financing Agreements to which the Company
is intended to be a party and perform its respective obligations thereunder.
Upon the request of any Rating Agency, the Company shall deliver or cause to be
delivered to each Rating Agency a true and complete copy of each Financing
Agreement relating to the financing of each Aircraft together with a true and
complete set of the closing documentation (including legal opinions) delivered
to the related Loan Trustee, Subordination Agent and Pass Through Trustee under
the related Participation Agreement.

                  (d) If after giving any Delivery Notice, there shall be a
delay in the delivery of an Aircraft, or if on the Scheduled Delivery Date of
an Aircraft the financing thereof in the manner contemplated hereby shall not
be consummated for whatever reason, the Company shall give the parties hereto
prompt notice thereof. Concurrently with the giving of such notice of

                                      -6-


postponement or subsequently, the Company shall give the parties hereto a
substitute Delivery Notice specifying the date to which such delivery and
related financing shall have been re-scheduled (which shall be a Business Day
before the Cut-off Date on which the Escrow Agents shall be entitled to
withdraw one or more Deposits under each of the applicable Deposit Agreements
to enable each applicable Pass Through Trustee to fund its purchase of the
related Equipment Notes). Upon receipt of any such notice of postponement, each
applicable Pass Through Trustee shall comply with its obligations under Section
5.01 of each of the Trust Supplements and thereafter the financing of the
relevant Aircraft shall take place on the re-scheduled Delivery Date therefor
(all on and subject to the terms and conditions of the relevant Financing
Agreements) unless further postponed as provided herein.

                  (e) Anything in this Section 1 to the contrary
notwithstanding, the Company shall have the right at any time on or before the
Scheduled Delivery Date of any Aircraft, and subsequent to its giving a
Delivery Notice therefor, to postpone the Scheduled Delivery Date of such
Aircraft so as to enable the Company to change its election to treat such
Aircraft as a Leased Aircraft or an Owned Aircraft by written notice of such
postponement to the other parties hereto. The Company shall subsequently give
the parties hereto a substitute Delivery Notice complying with the provisions
of Section 1(b) hereof and specifying the new Funding Date for such postponed
Aircraft (which shall be a Business Day occurring before the Cut-off Date and
on which the Escrow Agents shall be entitled to withdraw Deposits under each of
the applicable Deposit Agreements sufficient to enable each applicable Pass
Through Trustee to fund its purchase of the related Equipment Notes). In
addition, the Company shall have the further right, anything in this Section 1
to the contrary notwithstanding, to accept delivery of an Aircraft under the
Purchase Agreement on the Delivery Date thereof by utilization of bridge
financing of such Aircraft and promptly thereafter give the parties hereto a
Delivery Notice specifying a Funding Date not later than 60 days after the
Delivery Date of such Aircraft and no later than the Cut-off Date and otherwise
complying with the provisions of Section 1(b) hereof. All other terms and
conditions of this Note Purchase Agreement shall apply to the financing of any
such Aircraft on the re-scheduled Funding Date therefor except (i)the
re-scheduled Funding Date shall be deemed the Delivery Date of such Aircraft
for all purposes of this Section 1 and (ii)the related Financing Agreements
shall be amended to reflect the original delivery of such Aircraft to the
Company.

                  (f) If the Scheduled Delivery Date for any Aircraft is
delayed (a) more than 60 days beyond the last day of the month set forth
opposite such Aircraft under the heading "Scheduled Delivery Months" in
Schedule I hereto or (b) beyond the Delivery Period Termination Date, the
Company may identify for delivery a substitute aircraft therefor meeting the
following conditions (a "Substitute Aircraft"): (i) a Substitute Aircraft must
be a Boeing 747-400F aircraft manufactured after 1993, so long as after giving
effect thereto such substitution does not vary the Mandatory Economic Terms,
and (ii) the Company shall be obligated to obtain Rating Agency Confirmation in
respect of the replacement of any Aircraft by Substitute Aircraft. Upon the
satisfaction of the conditions set forth above with respect to a Substitute
Aircraft, the Aircraft to be replaced shall cease to be subject to this
Agreement and all rights and obligations of the parties hereto concerning such
Aircraft shall cease, and such Substitute Aircraft shall become and thereafter
be subject to the terms and conditions of this Agreement to the same extent as
such Aircraft.

                  (g) The Company shall have no liability for the failure of
any Pass Through Trustee to purchase Equipment Notes with respect to any
Aircraft or Substitute Aircraft, other than the Company's obligation, if any,
to pay the Deposit Make-Whole Premium pursuant to Section 4(a)(i) of this
Agreement.

                  (h) The parties agree that if, in connection with the
delivery of an Aircraft or Substitute Aircraft, any Owner Participant who is to
be a party to any Lease Financing Agreement or Special Financing Agreement
shall not be a "Citizen of the United States" within the meaning of Section
40102(a)(15) of the Act, then the applicable Lease Financing Agreements shall
be modified, consistent with the Mandatory Document Terms, to require such
Owner Participant to enter into a voting trust, voting powers, control rights
or similar arrangement satisfactory to the Company that (A) enables such
Aircraft or Substitute Aircraft to be registered in the United States and (B)
complies with the FAA regulations issued under the Act applicable thereto.

                  (i) Anything herein to the contrary notwithstanding, the
Company shall not have the right, and shall not be entitled, at any time to
request the issuance of Equipment Notes of any series to any Pass Through
Trustee in an aggregate principal amount in excess of the amount of the
Deposits then available for withdrawal by the Escrow Agent under and in
accordance with the provisions of the related Deposit Agreement.

Through Trustees to enter into, and to cause the Subordination Agent to enter

to perform its obligations under such Participation Agreement is subject to
satisfaction of the following conditions:

         (i) such Participation Agreement and the other Financing Agreements to
         be entered into pursuant to such Participation Agreement do not vary
         the Mandatory Economic Terms and contain the Mandatory Document Terms
         and (ii)any substantive modification of such Financing Agreements from
         the forms thereof attached to this Agreement do not materially and
         adversely affect the Certificateholders, and such certification shall
         be true and correct; and

                  (c) The Company shall have delivered to each Pass Through
         Trustee and each Liquidity Provider a certificate stating that the
         Company has previously deposited with the Depositary any and all Delay
         Increase Amounts required to be deposited pursuant to Section 3(a) of
         the Indemnity Agreement and that the Maturity Date or Rescheduled
         Maturity Date, as the case may be, for each Deposit relating to an
         Aircraft with respect to which a Delivery Notice has been delivered
         hereunder is a date occurring on or after the Funding Date specified
         in such Delivery Notice, and such certification shall be true and
         correct. For purposes of this Section 2(c), the terms "Delay Increase
         Amount," "Maturity Date" and "Rescheduled Maturity Date" shall have
         the meanings specified in the Indemnity Agreement.

                  Anything herein to the contrary notwithstanding, the
obligation of each Pass Through Trustee to purchase Equipment Notes shall
terminate on the Cut-off Date.

                              EMPLOYMENT AGREEMENT


        This EMPLOYMENT AGREEMENT, dated as of February 16, 1998 ("Agreement"),
is made by and between STEPHEN C. NEVIN ("EMPLOYEE") and ATLAS AIR, INC.

        WHEREAS, EMPLOYEE warrants that he is entering voluntarily into this
Agreement, and that no promises or inducements for this Agreement have been made
outside the terms and conditions referred to herein, and EMPLOYEE enters into
this Agreement without reliance upon any statement or representation by ATLAS or
any other person, concerning any fact material hereto.

        NOW, THEREFORE, in consideration of the covenants contained herein,
EMPLOYEE and ATLAS agree to this Employment Agreement for implementation
effective February 16, 1998.

        1. Definitions. 1.1 For purposes of this Agreement, "Cause" means (i)
any act or acts of material dishonesty by EMPLOYEE; (ii) failure of EMPLOYEE to

days of written notice of such notice; or (iii) the conviction of or "no
contest" plea by EMPLOYEE to any misdemeanor of moral turpitude or any felony;
or (iv) any violation of ATLAS corporate policies as set forth in the Employee
Handbook; provided that, if such violation is subject to cure, EMPLOYEE shall
have ten (10) days within which to cure such violation.

           1.2 "Permanent Disability" as used herein shall be deemed to have
been sustained by EMPLOYEE during his employment if he shall have been

from performing the duties assigned to him a period of six (6) consecutive
calendar months, and such Permanent Disability shall be deemed to have commenced
on the day following the end of such six consecutive calendar months.

        1.3 For purposes of this Agreement, a "Change in Control" shall be
deemed to have occurred upon the happening of two of the following:

            1.3.1 Michael Chowdry ceasing to have a direct or indirect
beneficial ownership (within the meaning of Rule 13(d)(3) promulgated under the
Securities and Exchange Act of 1934) of at least 51% of the combined voting
power of ATLAS's then outstanding voting securities entitled to vote generally
in the election of directors; or

            1.3.2 Michael Chowdry ceasing to be, on a substantially full-time

meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934
(excluding, for this purpose, any employee benefit plan of ATLAS or its
subsidiaries which acquires beneficial ownership of voting securities of ATLAS)
of beneficial ownership, within the meaning of Rule 13(d)(3) promulgated under
the Securities and Exchange Act of 1934, of a percentage of the combined voting
power of ATLAS's then outstanding voting securities entitled to vote generally
in the election of directors which is greater than the percentage beneficially
owned directly or indirectly by Michael Chowdry.

        1.4 "Good Reason" shall mean (i) a substantial reduction in EMPLOYEE's
title; (ii) a substantial change to EMPLOYEE's duties; (iii) or a reduction in

sharing.

        3.7 Stock Purchase Plan. On the first day of the month following one (1)
full year of service, EMPLOYEE will be eligible to participate in ATLAS's Stock
Purchase Plan whereby EMPLOYEE may purchase ATLAS stock at a fifteen percent

        3.8 Health Care. On the first day of the month following ninety (90)
