ITEM 1:  DESCRIPTION OF BUSINESS

GENERAL

     Frontier Airlines, Inc. ("the Company") is a low-fare, full-service airline
based in Denver, Colorado.  Principally serving markets abandoned by Continental
Airlines during that carrier's downsizing of its Denver hub in 1993 and 1994,
the Company currently operates routes linking its Denver hub to 15 cities in 12
states covering the western two-thirds of the United States.  The Company's
current route system extends from Denver to Los Angeles, San Diego and San
Francisco, California; Chicago, Illinois; Seattle/Tacoma, Washington; Las Vegas,
Nevada; Phoenix, Arizona; St. Louis, Missouri; Minneapolis/St. Paul, Minnesota;
Salt Lake City, Utah; Omaha, Nebraska; Albuquerque, New Mexico; El Paso, Texas;
and Bismarck and Fargo, North Dakota.  At present, the Company utilizes four
gates at the new Denver International Airport ("DIA") for approximately 54 daily
flight departures and arrivals.

     Organized in February 1994, the Company commenced flight operations in July
1994 with two leased Boeing 737-200 jet aircraft.   It has since expanded its
fleet to nine leased jets, including five Boeing 737-200s, two larger Boeing
737-300s added to the fleet in November 1995, and two additional Boeing 737-200s
added in June 1996.  The Company has agreed to lease a third Boeing 737-300 in
April 1997, at which time it plans to add one or more new cities to its route
system.

     Pending future aircraft availability, the Company plans to lease additional
jets in the 737 series for possible deliveries in the second half of 1996 and in
1997, which would permit the Company to further expand its lines of service.

     The Company's senior management team includes executives with substantial
service in the airline industry, including persons who occupied similar
positions at a former airline called Frontier Airlines that served regional
routes to Denver from 1950 to 1986.  From time to time, the former Frontier
Airlines served all of the Company's current and intended markets with jet
equipment from its Denver hub.

BUSINESS STRATEGY AND MARKETS

     The Company's business strategy is to provide service at low fares to high
volume markets from its hub at DIA.  The strategy is based on the following:

     * Filling gaps in flight frequencies in markets that the Company
       has selected from among the approximately 51 Denver routes vacated by
       Continental Airlines in 1993 and 1994.
                                                                               
     * Stimulating demand for its product by offering a combination of
       low fares, quality service and its own frequent flyer program as well
       as Continental Airlines' OnePass program.
                                                                               
     * Expanding its Denver hub operation and increasing its connecting
       traffic through the addition of service to other high volume markets.

     The Company's initial service pattern in 1994 was designed to fill flight
voids on routes to eight relatively small cities in North Dakota and Montana
where there was little or no jet competition to Denver after Continental's
flight terminations.  The Company has since refocused its marketing priorities
on more heavily traveled routes ---typically markets dominated by one or more
major airlines and characterized by high fares due to the lack of low-fare
competition prior to the Company's entry.  In line with its revised marketing
strategy, the Company in 1995 suspended service in most of its original markets,
and the aircraft used on these routes were redeployed to a  number of major
markets.  Other high volume markets were added in late 1995, upon the Company's
leasing of two Boeing 737-300 aircraft, and in May and June 1996, the latter in
conjunction with the addition of two additional Boeing 737-200 aircraft to the
Company's fleet.

     The Company plans to further develop its Denver hub by introducing low-fare
service in additional high volume markets formerly served by Continental
Airlines.  Management believes that potential markets for its planned route
expansions can support greater flight capacity than now provided by the
incumbent carriers and that passengers would welcome the restoration of
additional capacity, particularly at the low fares and quality service to be
offered by the Company.

MARKETING

     To support the marketing of its Denver hub, the Company has negotiated
various types of interline agreements with approximately 25 other carriers. The
Company has a "code-sharing" agreement with Continental Airlines at Denver. This
arrangement includes provisions for "through fares" on two routes and joint
ticketing and baggage services, among other passenger transfer features. At
present, the Company's customers receive these services when connecting at
Denver to Continental's flights to its three major hubs: Newark, New Jersey;
Houston, Texas; and Cleveland, Ohio. The Company and Continental Airlines,
Mexicana Airlines, Trans World Airlines, and USAir offer "joint fares"-- one
fare covering travel on two participating airlines. Also, the Company has
entered into several other agreements for various levels of joint ticketing and
baggage services with these and approximately 25 other carriers. United Airlines
and American Airlines currently accept the transfer of baggage to and from the
Company but do not accept the Company's tickets.

     The Company has implemented marketing strategies to maintain relationships
with travel agencies throughout its route system. The Company communicates with
the travel agents through personal visits by Company executives and sales
managers, mailings of sales literature, telemarketing and familiarization trips
to acquaint agents with the destinations and service of the Company.

     A key strategy in the Company's marketing efforts is its consumer and trade
advertising programs. The Company produces and places television, radio and
newspaper advertising in its system cities along with placements in selected
regional magazines. Advertisements also are placed in the major trade
publications primarily aimed at the travel agent community.

     The Company participates in the four major computer reservation systems
used by the travel agents to make airline reservations. On a cost-per-flight
segment basis, this has proved to be an efficient method for the Company to sell
its product. The Company also maintains a reservations center in Denver,
operated by its own personnel. The present facility and staffing are adequate
for the current size of the Company. The Company plans to expand this facility
at its current location as call volume increases.

     The Company pursues sales opportunities with corporate accounts, meeting
and convention arrangers, government travel offices and vacation clubs. Personal
sales calls, direct mail and telemarketing are the primary tools in attracting
this business. The Company offers air/ground vacation packages to Phoenix, Las
Vegas and other destinations on its route system.

     An important marketing tool in today's airline environment is the frequent
flyer program. The Company joined Continental's OnePass program in January 1995.
The selection of OnePass was based on the established membership base in the
cities served by the Company and consistent high marks that the program has
received when compared with other programs. The Company also maintains a
separate frequent flyer program for travel over its own routes. The emphasis of
this program is simplicity with one free ticket awarded for each ten trips
flown.

PRODUCT PRICING

     The Company offers all of its seats at various discount fares reducing the
cost of travel in markets it enters by as much as 60 percent. Seat inventories
on each flight are managed through a yield management system. The Company
generally offers discounts with three levels of advance purchase requirements
and at "peak" and "off-peak" levels, the lowest of which are available on the
least heavily traveled days of the week. In contrast to most carriers, the
Company does not require travelers to have a Saturday overnight stay to take
advantage of these discount rates. Unlike most other carriers, the Company does
not charge a premium for one-way fares.

                                      -3-

COMPETITION

     The Airline Deregulation Act of 1978 produced a highly competitive airline
industry, freed of certain government regulations that for 40 years prior to the
Act had dictated where domestic airlines could fly and how much they could
charge for their services. Since then small start-up carriers such as the
Company have entered markets long dominated by large airlines with substantially
greater resources such as United Airlines, American Airlines, Trans World
Airlines and Delta Air Lines.

     As shown in the following chart as of June 1996, the Company competes
principally with United Airlines, the dominant carrier at Denver with a market
share of approximately 70% as of April 1996.  This gives United a significant
competitive advantage compared to the Company and other carriers serving Denver.

     United matches the Company's prices on selected competitive flights.
Central to the prospects for the Company's success is that United will not
dramatically undercut the Company's pricing. Management believes that the
Company's strategy to fly to its scheduled cities on average two to three times
per day will cause an increase in total enplanements by stimulating air traffic
and should not cause United to react in a manner which could have a material
adverse effect on the Company's business. However, there can be no assurance
that this will be the case.

     In addition to direct competition with United, the Company indirectly faces
low fare competition in some markets from Western Pacific Airlines ("Western
Pacific") operating from Colorado Springs, approximately 75 miles south of
Denver. As of June 1996, Western Pacific was serving 20 cities from Colorado
Springs, including seven cities served by the Company from Denver. The Company's
lowest fares to these seven destinations on average generally are within $10 of
those charged by Western Pacific, which management believes is offset by the
cost of ground transportation between Denver and Colorado Springs, combined with
lost travel time in city-to-city surface transit.

     The Company has a marketing or "code-sharing" alliance with Continental
Airlines at Denver. Among other benefits, this arrangement provides prominent
listings of two connecting flights operated by the two carriers in the computer

                                      -4-
<PAGE>
 
reservations systems used by travel agents.  In the Denver-North Dakota market,
United has a similar type of code-sharing alliance with Great Lakes/United
Express, which, since United controls the majority of the Denver hub market,
gives Great Lakes/United Express a substantial advantage in capturing connecting
traffic.  The Company believes that it has a competitive advantage in serving El
Paso, Texas, where it offers the only direct service to and from Denver, and in
serving Chicago/Midway, where it offers the only nonstop service to and from
Denver.

AIRCRAFT

     As of June 1996, the Company leases nine Boeing 737 twinjet aircraft
including five Boeing 737-200 aircraft manufactured in 1968 and 1969, two Boeing
737-200 aircraft manufactured in 1981, and two Boeing 737-300 aircraft
manufactured in 1985 and 1986. The two Boeing 737-300 aircraft have 136 and 138
passenger seats configured in a single class of service. Two of the Boeing 737-
200 aircraft have 119 passenger seats and the other five Boeing 737-200 aircraft
have 108 passenger seats, all configured in a single class of service. The lease
terms for five of the leased five Boeing 737-200 aircraft expire between July
and October 1997, although the Company has the right to extend the initial lease
terms for two additional renewal terms of two years each. The lease terms for
the Boeing 737-300 aircraft expire in the year 2000. The lease terms for two
Boeing 737-200 aircraft expire in the year 2001.

     The demand for Boeing 737 aircraft has increased markedly in the past year.
The Company is seeking to lease additional aircraft in order to expand its
service and route system. However, there can be no assurance that additional
suitable aircraft will be available to the Company at favorable lease rates and
terms, or at the times needed for implementation of the Company's plan of
operation. See "Management's Discussion and Analysis of Financial Condition and
Plan of Operation-Liquidity and Capital Resources."

MAINTENANCE AND REPAIRS

     All aircraft maintenance and repairs are accomplished in accordance with
the Company's maintenance program approved by the United States Federal Aviation
Administration ("FAA"). Spare or replacement parts are maintained by the Company
primarily in Denver. Certain of these parts are supplied through a contractual
arrangement with a major airline, with others purchased from other airline or
vendor sources. There are two categories of aircraft maintenance and repair:
routine servicing and checks accomplished on a daily or weekly schedule, and
major maintenance. The Company's major maintenance has been performed by two
major airlines, Continental Airlines and USAir. Routine maintenance is performed
by the Company's mechanics and by outside contractors approved by the FAA.

     Under its aircraft lease agreements, the Company pays all expenses relating
to the maintenance and operation of the Company's aircraft, and the Company is
required under its lease agreements to pay monthly maintenance reserve deposits
to the lessors based on usage. Maintenance reserve deposits will be applied
against the cost of major maintenance, which is scheduled to occur in late 1996
for seven of the Company's aircraft.

     The Company's monthly completion factors for its fiscal year ending March
31, 1996 ranged from 95% to 99%. The completion factor is the percentage of the
Company's scheduled flights that were operated by the Company (i.e., not
canceled). Flights not completed were canceled principally as a result of either
weather or mechanical problems. There can be no assurance that the Company's
aircraft will continue to be sufficiently reliable over longer periods of time.

     Beginning in September 1996 and ending in February 1997 the Company will be
performing major routine maintenance on seven of its nine aircraft.  Each
aircraft will be out of service for approximately one month.  The Company is in
the process of locating an aircraft to lease during this maintenance cycle.  If
the Company is unable to obtain a short-term lease, the Company will only have
eight aircraft in service during this time.  Management believes that it has
adequately accrued for the expenses of this major maintenance cycle.  In October
1996, one of its B737-200 aircraft leased in June 1996 will be removed from
service and "hush-kitted" at the lessor's expense.  The Company is estimating
that this will take approximately eight days.

                                      -5-
<PAGE>
 
FUEL
 
     During the fiscal years ending March 31, 1995 and 1996, jet fuel accounted
for 14.5% and 14.4%, respectively, of the Company's operating expenses.  The
Company has arrangements with major fuel suppliers for substantial portions of
its fuel requirements, and management believes that such arrangements assure an
adequate supply of fuel for current and anticipated future operations. However,
the Company has not entered into any agreements that fix the price of fuel over
any period of time. Jet fuel costs are subject to wide fluctuations as a result
of sudden disruptions in supply beyond the Company's control. Therefore, the
future availability and cost of jet fuel cannot be predicted with any degree of
certainty.  Fuel prices increased slightly during the fiscal year ended March
31, 1996.

     Newer aircraft are more fuel efficient than the Company's Boeing 737-200
aircraft due to improved aircraft airframe design and engine technology.
Significant increases in the price of jet fuel would result in a higher increase
in the Company's overall total costs than those of competitors whose entire
fleet consists of more fuel efficient aircraft. Increases in fuel prices or a
shortage of supply could have a material adverse affect on the Company's
operations and financial results. The Company's ability to pass on increased
fuel costs to passengers through price increases or fuel surcharges may be
limited, particularly given the Company's low fare strategy.

     In August 1993, the United States increased taxes on domestic fuel,
including aviation fuel, by 4.3 cents per gallon. Airlines were exempt from this
tax increase until October 1, 1995, at which time airlines became subject to the
tax increase. The airline industry has proposed a continuation of this
exemption. The fuel tax increases the Company's annual costs by approximately
$1,290,000 assuming its current nine aircraft fleet and an annual consumption of
approximately 30 million gallons of fuel. See "Management's Discussion and
Analysis of Financial Condition and Plan of Operation."

INSURANCE

     The Company carries $500 million per aircraft per occurrence in property
damage and passenger and third-party liability insurance, and insurance for
aircraft loss or damage as required by its aircraft lease agreements, and
customary coverage for other business insurance. While the Company believes such
insurance is adequate, there can be no assurance that such coverage will fully
protect it against all losses which it might sustain. Moreover, the Company's
insurance for aircraft loss or damage carries a deductible requiring the Company
to pay up to the first $500,000 of loss or damage unless the aircraft is
determined to be a total loss. The Company's property damage and passenger and
third-party liability insurance coverage exceeds the minimum amounts required by
the United States Department of Transportation ("DOT") regulations.

EMPLOYEES

     As of June 1996, the Company had 615 employees, including 528 full-time and
87 part-time personnel. The Company's employees included 99 pilots, 129 flight
attendants, 140 customer service agents, 129 reservations agents, 26 mechanics
and related personnel, 65 general management personnel, and 27 personnel
performing other miscellaneous functions. The Company considers its relations
with its employees to be good.

     The Company believes it operates with lower personnel costs than many
established airlines, principally due to lower base salaries and greater
flexibility in the utilization of personnel. There can be no assurance that the
Company will continue to realize these advantages over established or other air
carriers for any extended period of time. None of the Company's employees is
represented by a labor union. If unionization of the Company's employees occurs,
the Company's costs could materially increase.

     Training, both initial and recurring, is required for many employees.
Pilots, flight attendants, ground service personnel, reservationists and
mechanics are trained by the Company. FAA regulations require pilots to be
licensed as commercial pilots, with specific ratings for aircraft to be flown
and to be medically certified as physically fit. Licenses and medical
certification are subject to periodic continuation requirements including
recurrent training and recent flying experience. Mechanics, quality control
inspectors and flight dispatchers must be licensed and qualified for specific
aircraft. Flight attendants must have initial and periodic competency fitness
training and certification. Training programs are subject to approval and
monitoring by the FAA. Management personnel directly involved in the supervision
of flight operations,

                                      -6-
<PAGE>
 
training, maintenance and aircraft inspection must meet experience standards
prescribed by FAA regulations. Employees performing safety-sensitive functions
are subject to pre-employment and subsequent random drug and alcohol testing.

GOVERNMENT REGULATION

     All interstate air carriers are subject to regulation by the DOT and the
FAA under the Federal Aviation Act. The DOT's jurisdiction extends primarily to
the economic aspects of air transportation, while the FAA's regulatory authority
relates primarily to air safety, including aircraft certification and
operations, crew licensing and training and maintenance standards.

     In general, regulation of interstate air carriers in terms of market entry
and exit, pricing and inter-carrier agreements has been greatly reduced
subsequent to enactment of the Airline Deregulation Act of 1978. As a result,
the level of regulation to which the Company and other airlines is subject has
been greatly reduced. By the same token, the availability to the Company of
regulatory protection from competition has been virtually eliminated.

     U.S. Department of Transportation. The Company holds a Certificate of
Public Convenience and Necessity ("DOT Certificate") issued by the DOT which
allows the Company to engage in air transportation. Pursuant to law and DOT
regulation, each United States carrier must qualify as a United States citizen,
which requires that its President and a least two-thirds of its Board of
Directors and other managing officers be comprised of United States citizens;
that not more than 25% of its voting stock may be owned by foreign nationals,
and that the carrier not be otherwise subject to foreign control.

     U.S. Federal Aviation Administration. The Company also holds an operating
certificate ("FAA 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 maintenance,
and technical standards for flight, communications and ground equipment. The
Company must have and maintains FAA certificates of airworthiness for all of its
aircraft. The Company's flight personnel, flight and emergency procedures,
aircraft and maintenance facilities are subject to periodic inspections and
tests by the FAA.

     In May 1996 a relatively new domestic airline, as is the Company, sustained
an accident in which one of its aircraft was destroyed and all persons on board
were fatally injured.  In June that airline agreed at the FAA's request to cease
all of its flight operations for an indefinite period of time.  Should the
Company experience a similar accident, it is probable that there would be a
material adverse effect on the Company's business.

     The DOT and FAA also have authority under the Aviation Safety and Noise
Abatement Act of 1979, the Airport Noise and Capacity Act of 1990 ("ANCA") and
Clean Air Act of 1963 to monitor and regulate aircraft engine noise and exhaust
emissions. The Company is required to comply with all applicable FAA noise
control regulations and with current exhaust emissions standards. According to
FAA rules, each new entrant airline such as the Company must presently have at
least 25% of its fleet in compliance with the FAA's Stage 3 noise level
requirements. The balance of each airlines' fleet must be brought into
compliance with Stage 3 in phases, with 50% compliance by January 1997, 75%
compliance by January 1999 and full compliance by January 2000. The Company's
aircraft fleet is currently in compliance with Stage 3 noise level requirements.

     As a result of litigation and pressure from airport area residents, airport
operators have taken local actions over the years to reduce aircraft noise.
These actions have included regulations requiring aircraft to meet prescribed
decibel limits by designated dates, curfews during night time hours,
restrictions on frequency of aircraft operations and various operational
procedures for noise abatement. ANCA recognizes the right of airport operators
with special noise problems to implement local noise abatement procedures as
long as such procedures do not interfere unreasonably with the interstate and
foreign commerce of the national air transportation system. ANCA generally
requires FAA approval of local noise restrictions on Stage 3 aircraft and
establishes a regulatory notice and review process for local restrictions on
Stage 2 aircraft. An agreement between the City and County of Denver and another
city adjacent to DIA precludes the use of Stage 2 aircraft, such as certain of
the Company's Boeing 737-200 aircraft, on one of DIA's runways. On occasion,
this results in longer taxi times for the Company's aircraft than would
otherwise be the case. However, this has not had a material adverse effect on
the Company's 

                                      -7-
<PAGE>
 
operations. The Company's operations could be adversely affected if additional
restrictions are imposed at DIA or if locally-imposed regulations become
restrictive at any other cities on the Company's routes.

         Miscellaneous. All air carriers are also subject to certain provisions
of the Communications Act of 1934 because of their extensive use of radio and
other communication facilities, and are required to obtain an aeronautical radio
license from the Federal Communications Commission ("FCC"). To the extent that
the Company is subject to FCC requirements, it takes all necessary steps to
comply with those requirements.

         The Company's operations may become subject to additional federal
regulatory requirements in the future under certain circumstances. For example,
if the Company's employees were to unionize, the Company's labor relations would
be covered under Title II of the Railway Labor Act of 1926 and would be subject
to the jurisdiction of the National Mediation Board. During a period of past
fuel scarcity, air carrier access to jet fuel was subject to allocation
regulations promulgated by the Department of Energy. To the extent that the
Company seeks to provide international air transportation in the future, it will
be required to obtain additional authority from the DOT and become subject to
other regulatory requirements imposed by affected foreign jurisdictions.

ITEM 2:  DESCRIPTION OF PROPERTY

         The Company has leased approximately 21,100 square feet of office space
in Denver with terms ending in 1999 and 2001 at a current annual cost of
$237,000 for the fiscal year ending March 31, 1997. This facility provides space
for the Company's reservation center together with space for administrative
activities including senior management, purchasing, accounting, sales,
marketing, advertising and human resources.

         Each airport location requires leased space associated with gate
operations, ticketing and baggage operations. The ticket counters, gates and
airport office facilities at each of the airports the Company serves are leased
from the appropriate airport authority or subleased from other airlines.

         The Company has entered into an airport lease and facilities agreement
with the City and County of Denver at DIA that expires in 2005. The Company
subleases ticket counter space and four gates at DIA from Continental Airlines.
See "Management's Discussion and Analysis of Financial Condition and Plan of
Operation-Liquidity and Capital Resources."

         The Company currently leases nine aircraft and has agreed to lease one
more aircraft for delivery in April 1997. See "Aircraft" and Notes 5 and 12 to
Financial Statements.

ITEM 3:  LEGAL PROCEEDINGS

         There are no legal proceedings pending in which the Company is a party
or of which any of the Company's property is the subject that are not adequately
covered by insurance maintained by the Company, or which, if adversely decided
would have a material adverse effect on the Company's business. From time to
time, the Company may become involved in routine litigation incidental to its
business.

ITEM 4:  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         No matter was submitted during the fourth quarter of the fiscal year
covered by this Report to a vote of security holders of the Company through the
solicitation of proxies or otherwise.

WARRANTS AND OPTIONS
 
     The Company issued 2,670,000 warrants to purchase Common Stock in
conjunction with a private placement and its initial public offering with one
warrant entitling a warrant holder to purchase a share of Common Stock for a
purchase price of $5.00.  These warrants were subject to redemption at $.05 per
warrant by the Company on 45 days written notice if certain conditions were met.
The Company met these conditions in May 1996 and on May 14, 1996, the Company
notified the warrant holders of the Company's intent to exercise its redemption
rights with respect to the warrants not exercised on or before June 28, 1996.
As of June 14, 1996, 626,060 of the warrants had been exercised.

      At the completion of the Company's initial public offering, an underwriter
acquired a warrant to purchase up to 110,000 shares of common stock and 110,000
warrants, exercisable at a price equal to $5.525 per share of common stock and
$.325 per Warrant.  Underwriters in a secondary public offering by the Company
received a warrant to purchase 168,500 shares of Common Stock at $5.55 per
share.  The Company also has issued to each of its two Boeing 737-300 aircraft
lessors a warrant to purchase 100,000 shares of Common Stock at a purchase price
of $500,000 per warrant, and two warrants to a Boeing 737-200 lessor to purchase
70,000 shares of common stock at an exercise price of $503,300 per warrant.  The
warrants issued to aircraft lessors, to the extent not earlier exercised, expire
on the expiration date of the aircraft leases.

      As of March 31, 1996, the Company also has granted stock options to
purchase up to 1,731,250 shares of Common Stock, substantially all of which
options are currently exercisable at exercise prices ranging from $1.00 to $3.75
per share.

DIVIDEND POLICY

      The Company has not declared or paid dividends or paid dividends on its
Common Stock. The Company currently intends to retain any future earnings to
fund operations and the continued development of its business, and, thus, does
not expect to pay any cash dividends on its Common Stock in the foreseeable
future. Future cash dividends, if any, will be

                                      -9-
<PAGE>
 
determined by the Board of Directors and will be based upon the Company's
earnings, capital requirements, financial condition and other factors deemed
relevant by the Board of Directors.

ITEM 6:  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

GENERAL

     The Company's flight operations began at Stapleton International Airport
("Stapleton") on July 5, 1994 with two Boeing 737-200 aircraft operating eight
daily flights between Denver, Colorado and four North Dakota cities. Since that
time, the Company has increased the number of markets it serves and the number
of flights offered. The Company placed three additional Boeing 737-200 aircraft
in service in 1994 and operated a total of five aircraft through October 1995.
In October 1995, the Company leased two Boeing 737-300 aircraft which were
placed in service during November 1995 in conjunction with adding four new, high
volume routes linking Denver to Los Angeles and San Francisco, California,
Minneapolis-St. Paul, Minnesota, and Salt Lake City, Utah. The Company
significantly rescheduled its flights in 1995 through the elimination of Minot
and Grand Forks, North Dakota and all four of its Montana destinations, and the
addition of Omaha, Nebraska, Las Vegas, Nevada, Chicago (Midway), Illinois and
Phoenix, Arizona to its schedule. Flights to Seattle/Tacoma commenced on May 1,
1996, and flights to San Diego, California and St. Louis, Missouri commenced on
June 1, 1996 in conjunction with the addition of two additional Boeing 737-200
jets to the Company's fleet. After adding these new cities, the Company's nine
aircraft serve 15 cities from its Denver base of operations. On February 28,
1995, Stapleton was closed and the Company's flight operations were moved to the
newly opened Denver International Airport ("DIA").

     The Company has agreed to lease a third Boeing 737-300 in April 1997, at
which time it plans to add one or more new cities to its route system.  Pending
future aircraft availability, the Company plans to lease additional jets in the
737 series for possible deliveries in the second half of 1996 and in 1997, which
would permit the Company to further expand its lines of service.  Demand and
competition for Boeing 737 aircraft has increased significantly in the past
year.

     The Company's operations prior to July 5, 1994 were limited to start-up
activities, including the establishment of its general office operation, initial
financing activities, completing the Department of Transportation and Federal
Aviation Administration application process, training crews and other activities
associated with a start-up airline. These activities generated pre-operating
expenses of $1,179,000, which are included in the Company's results of
operations for the year ended March 31, 1995. In addition, the Company modified
its initial operating strategy during the fiscal year ended March 31, 1995 and
further modified and expanded operations during the fiscal year ended March 31,
1996.  Therefore, the Company's results of operations for the fiscal years ended
March 31, 1995 and 1996 are not necessarily comparable or indicative of future
operating results.

     Small fluctuations in the Company's yield per RPM or expense per ASM can
significantly affect operating results because the Company, like other airlines,
has high fixed costs and low operating margins in relation to revenues. Airline
operations are highly sensitive to various factors, including the actions of
competing airlines and general economic factors, which can adversely affect the
Company's liquidity, cash flows and results of operations.

     In June 1995, the Company contributed 137,340 shares of Common Stock to its
employee stock ownership plan ("ESOP").  The compensation expense attributable
to the 137,340 contributed shares totaled $721,000, which the Company recognized
during the year ended March 31, 1996.   See Note 9 to the Financial Statements.

RESULTS OF OPERATIONS

     Year ended March 31, 1995. The Company incurred a net loss of $7,999,000,
or $2.56 per share, for its first full fiscal year ended March 31, 1995. The
loss was caused by several factors. The Company incurred pre-operating costs of
$1,179,000 in connection with its start-up activities, comprised of expenses
related to flight operations of $284,000 and general and administrative expenses
of $895,000. The Company believes that a substantial portion of these costs were
non-recurring. The Company had insignificant operating revenues during this pre-
operating period.

                                      -10-
<PAGE>
 
      The Company incurs substantial costs in ramping up its flight operations
as it begins service to new destinations. Commencement of service in new markets
is characterized by relatively high initial operating costs with a gradual
buildup of revenues over a 60 to 120 day period until the Company achieves
anticipated market penetration. As a result, the Company can expect to incur
losses related to the new markets during at least the first few months of
operation in these new markets. Operating results for fiscal 1995 and 1996 also
were adversely affected by the Company's need to modify its initial strategy.
The Company's initial strategy in July 1994 was to enter regional markets where
a series of earlier route abandonments by Continental Airlines and other major
airlines had resulted in either only limited jet service to Denver, service
transfers to commuter carriers operating small turboprop aircraft, or no nonstop
or direct service to Denver at all. In its early planning, the Company had
expected to capture two types of traffic on its selected routes: "local"
passengers (those either beginning or ending their trips in Denver) and
"connecting" passengers (those transferring to or from other airlines for
flights to destinations beyond Denver).

      After entering its first markets in July 1994, the Company encountered
difficulty in attracting connecting traffic because United Airlines, Denver's
dominant carrier, chose not to enter into interline agreements with the Company.
The Company's ability to attract connecting traffic was further inhibited by the
substantial reduction in service of Continental Airlines at Denver. As a result,
the Company modified its strategy to develop its own connecting hub at Denver.
The Company modified and expanded its route structure to routes that are more
dependent on local traffic and less dependent on connecting traffic pending the
development of its hub in Denver. The addition of new markets increased the
Company's start-up costs, and the Company again experienced a gradual buildup of
revenue in each of the new markets as they were opened. In late 1994 and early
1995, the Company implemented a low fare strategy and focused on markets with
greater potential volumes of local traffic.

                                      -11-
<PAGE>

     Year ended March 31, 1996. The Company did not recognize any revenue or
related direct costs of operations until July 5, 1994. Therefore, a discussion
regarding comparisons between the year ended March 31, 1996 and the comparable
period ended March 31, 1995 is not necessarily meaningful. The Company incurred
a net loss of $5,582,000, or $1.23 per share, for the year ended March 31, 1996.
On September 25, 1995, the Company eliminated all four of its Montana
destinations, reduced frequency to Bismarck and Fargo, North Dakota, and
inaugurated routes to Chicago (Midway), Illinois and Phoenix, Arizona. During
November 1995, the Company began service between Denver and an additional four
markets -- Los Angeles and San Francisco, California, Minneapolis-St. Paul,
Minnesota, and Salt Lake City, Utah.

     The Company completed the integration of the two Boeing 737-300s leased
during the quarter ended December 31, 1995 and the restructuring of its
connecting hub and route system related to these aircraft during mid November
1995. As a result of the completion of the first phase of its new business and
marketing strategy, the Company had its first profitable quarter during the
fourth fiscal quarter ended March 31, 1996 with net income of $816,000.

(1)  "Revenue passenger miles," or RPMs, are determined by multiplying the
     number of fare-paying passengers carried by the distance flown.
(2)  "Available seat miles," or ASMs, are determined by multiplying the number
     of seats available for passengers by the number of miles flown.
(3)  "Passenger load factor" is determined by dividing revenue passenger miles
     by available seat miles.
(4)  "Break-even load factor" is the passenger load factor that will result in
     operating revenues being equal to operating expenses, assuming
     constant revenue per passenger mile and expenses
(5)  "Block hours" represent the time between aircraft gate departure and
     aircraft gate arrival.
(6)  "Average daily block hour utilization" represents the total block hours
     divided by the weighted average number of aircraft days in service.
(7)  "Yield per RPM" is determined by dividing passenger revenues by revenue
     passenger miles.
(8)  "Yield per ASM" is determined by dividing passenger revenues by available
     seat miles.
(9)  "Average fare"  excludes revenue included in passenger revenue for non-  
     revenue passengers, administrative fees, and revenue recognized for unused
     tickets that are greater than one year from issuance date.

REVENUES

     General. Airline revenues are primarily a function of the number of
passengers carried and fares charged by the airline. The Company believes that
revenues will gradually increase in a new market over a 60 to 120 day period as
anticipated market penetration is achieved. This occurred during the three
months ended September 30, 1994, which was the Company's first three months of
flight operations and, more recently, in January, September and November 1995
when

                                      -14-
<PAGE>
 
the Company commenced service to Omaha, Nebraska, Las Vegas, Nevada,
Chicago (Midway), Illinois, Phoenix, Arizona, Los Angeles and San Francisco,
California, Minneapolis-St. Paul, Minnesota and Salt Lake City, Utah.  The
Company expects that this will also occur in its Denver - Seattle/Tacoma, San
Diego and St. Louis markets which it inaugurated in May and June, 1996.

     The Company's results are highly sensitive to changes in fare levels. Fare
pricing policies have a significant impact on the Company's revenues.  Following
is a table of the Company's average fares:

                      December 31, 1995             $ 80
                      March 31, 1996                $ 93

     On commencement of operations, the Company set its fares at prevailing
competitive fares within the markets entered.  In connection with the
modification in the Company's strategy, the Company reduced fares to maximize
traffic and revenue.  The initial stimulative effect on the markets involved was
positive when system-wide prices were reduced in September 1994.  On March 1,
1995, in connection with the opening of DIA, the Company increased its local
Denver fares by up to $35 to offset the increased costs of DIA and other
expected cost increases and the Company's average fare peaked at $96 for the
quarter ended June 30, 1995.  During the quarter ended September 30, 1995, the
Company reduced its fares system-wide in order to "re-stimulate" markets and
match competitors' fares.  During the quarter ended December 31, 1995, the
Company's average fare decreased to $80 as a result of introductory fares for
its two new markets added in late September 1995 and the four new markets added
during the month of November 1995.  The Company's average fare for the quarter
ended March 31, 1996 increased to $93 largely as a result of the Company's new
yield management system, the elimination of introductory fares, and the
expiration of excise taxes on air transportation.  Management believes that the
excise tax or some other type of tax will be likely in the future and may be as
high as 10% of the fare.  Given the elasticity of passenger demand, increases in
fares will result in a decrease in passenger demand.  To maintain passenger
traffic in the face of an excise tax increase may require some downward
adjustment in net fares realized by the Company.  The Company cannot completely
predict future fare levels, which depend to a substantial degree on actions of
competitors.  When sale prices or other price changes are made by competitors in
the Company's markets, the Company believes that it must, in most cases, match
these competitive fares in order to maintain its market share. Passenger
revenues are seasonal in each market. The Company expects the March quarter to
be its weakest with the September quarter to be its strongest.

     Year ended March 31, 1995. Passenger revenues totaled $23,883,000 for the
fiscal year ended March 31, 1995 and represented 97.1% of total revenues.
Passenger revenues increased each quarter during the year ended March 31, 1995.
The Company was able to increase its aircraft utilization through the schedule
adjustments made in January 1995 and other minor adjustments made from time to
time during the year.

     An airline's break-even load factor is the passenger load factor that will
result in operating revenues being equal to operating expenses, assuming
constant revenue per passenger mile and expenses. For the year ended March 31,
1995, the Company's break-even load factor was 54.4% compared to a passenger
load factor of 41.2%. The Company's low load factors during its first quarter of
flight operations ended September 30, 1994 reflect the start-up nature of the
airline, an increase in capacity from two to four aircraft, the difficulties the
Company encountered in entering the connecting traffic market at Denver and the
modification to the Company's initial strategy to create its own hub at Denver
and to enter higher volume markets. The Company's improved load factors in the
quarter ended December 31, 1994 reflect this result, along with higher seasonal
passenger traffic. The Company's load factor for its fourth fiscal quarter ended
March 31, 1995 was affected by several factors. Seasonality and a change in the
Company's route structure in January 1995 to eliminate Minot and Grand Forks,
North Dakota and to add Omaha and Las Vegas reduced load factors in January.
Load factors improved in February and March 1995 as the Company's strategy
received greater acceptance. Seasonal travel in March 1995



                                      -15-
<PAGE>
 
increased RPMs to their highest level for the Company's first operating fiscal
year. The Company believes that its load factors were favorably impacted by its
low fare strategy and adversely affected by modifications to the Company's
strategy requiring entry into new markets. In addition, the Company believes
that its load factors were adversely affected by passenger uncertainty
associated with the closing of Stapleton and the opening of DIA which has
reduced air travel through Denver and caused the Company and other airlines at
DIA to increase fares to cover higher operating costs.

     Fare pricing policies have a significant impact on the Company's revenues.
The Company's average fare for the fiscal year ended March 31, 1995 for all
passengers was $89, net of federal excise taxes. Initially, the Company set its
fares at prevailing competitive fares within the markets entered. In connection
with the modification in the Company's strategy, the Company reduced fares to
maximize traffic and revenue. The initial stimulative effect on the markets
involved was positive when system-wide prices were reduced in September 1994.
From the commencement of the Company's flight operations on July 5, 1994 through
September 30, 1994, the Company's average fare was $104, excluding federal
excise taxes. For the period of October 1, 1994 through December 31, 1994, the
comparable average fare was $83. From January 1, 1995 through March 31, 1995,
the Company's average fare was $91. On March 1, 1995, in connection with the
opening of DIA, the Company increased its local Denver fares by up to $35 to
offset the increased costs of DIA and other expected cost increases. This
accounted for the increase in the Company's average fares from the previous
quarter. The Company believes that this fare increase has reduced the
stimulative effect the Company experienced from its low fare pricing strategy.

     Cargo revenues, consisting of revenues from freight and mail service,
totaled $567,000 and represented 2.3% of total operating revenues. This adjunct
to the passenger business is highly competitive and depends heavily on aircraft
scheduling, alternate competitive means of same day delivery service and
schedule reliability.

     Other revenues, comprised principally of liquor sales and excess baggage
fees, totaled $146,000 and represented less than one percent of total operating
revenues.

     Year ended March 31, 1996. Passenger revenues totaled $68,530,000 for year
ended March 31, 1996 and represented 97.4% of total revenues. Passenger revenues
increased each quarter during the year ended March 31, 1996 principally as a
result of the Company reaching full market penetration on its earlier routes,
increasing its aircraft utilization through schedule adjustments, the increase
in the average aircraft in service, and the introduction of new high volume
markets. This is reflected in the aircraft block hour utilization described in
the table above.

     For the year ended March 31, 1996, the Company's break-even load factor was
61.8% compared to a passenger load factor of 56.9%. The Company's passenger load
factor increased each quarter during the year ended March 31, 1996. The Company
believes that its load factors were adversely affected during this period by
passenger uncertainty associated with the closing of Stapleton and the opening
of DIA and the increased fares charged by the Company and other airlines at DIA
to cover higher operating costs coupled with new competition offering low fares
at the Colorado Springs, Colorado airport which is approximately 75 miles south
of Denver. Although the Company's load factor will fluctuate from period to
period, management believes that, based on the Company's current low fare
strategy and operations, its break-even load factor will range from 58% - 62% as
demonstrated in the quarter ended March 31, 1996 when the Company had a break-
even load factor of 59.7%, a load factor of 61.7% and operating income of
$833,000.

     Cargo revenues totaled $1,148,000 for the year ended March 31, 1996 or 1.6%
of total revenue. This adjunct to the passenger business is highly competitive
and depends heavily on aircraft scheduling, alternate competitive means of same
day delivery service and schedule reliability.

     Other revenues comprised principally of liquor sales, excess baggage fees,
and ground handling services for other carriers totaled $714,000 or 1.0% of
revenue. Of the $714,000, $234,000 represented revenues earned by providing
ground handling services to other carriers in Omaha and its Montana cities.
These ground handling services were discontinued in September 1995 when the
Company terminated its Montana service and the termination of its contract in
Omaha.

OPERATING EXPENSES

     Year Ended March 31, 1995. Operating expenses include those related to
flight operations, aircraft and traffic servicing, maintenance, promotion and
sales, general and administrative and depreciation and amortization. The
information provided below excludes pre-operating expenses related to flight
operations of $284,000 and general and administrative expenses of $895,000.

     Flight Operations. Flight operations expenses of $12,548,000 were 39.8% of
total operating expenses and include all expenses related directly to the
operation of the aircraft including fuel, lease and insurance expenses, pilot
and flight attendant compensation, in flight catering, crew overnight expenses,
flight dispatch and flight operations administrative expenses.

     Aircraft fuel expenses include both the direct cost of fuel as well as the
cost of delivering fuel into the aircraft. Aircraft fuel costs of $5,081,000 for
7,681,000 gallons used resulted in an average fuel cost per gallon during the
year of 66.15c. Fuel consumption for the year averaged 790 gallons per block
hour but varied monthly as weather and flight planning changed considerably by
season. Fuel prices during the year were generally stable to declining which was
favorable to the Company's operating results. Fuel prices are subject to change
weekly as the Company does not purchase supplies in advance for inventory. In
August 1993, the United States increased taxes on domestic fuel, including
aviation fuel, by 4.3 cents per gallon. Airlines were exempt from this tax
increase until October 1, 1995. See "-- Year Ended March 31, 1996" below.

     Aircraft lease and insurance expenses, including passenger liability
insurance, totaled $3,555,000 for the fiscal year ended March 31, 1995.

     Pilot and flight attendant compensation totaled $1,927,000 for the fiscal
year ended March 31, 1995. With a scheduled passenger operation, and with
salaried rather than hourly crew compensation, the Company's expenses for flight
operations are largely fixed, with flight catering expenses the principal
exception. Higher aircraft utilization produces a more favorable cost per block
hour or per ASM, and the Company benefited from an increase in aircraft
utilization during fiscal 1995.

     Aircraft and Traffic Servicing. Aircraft and traffic servicing expenses
were $5,925,000 and represented 18.8% of total operating expenses. These include
all expenses incurred at the airports as well as station operations
administration and flight operations ground equipment maintenance. Station
expenses include landing fees, facilities rental, station labor and ground
handling expenses. These costs generally increased throughout the year as the
Company added stations to its schedule and related airport departures increased.
The Company served four cities in July 1994 and increased service to eight
cities by October 1994. Daily flights increased from 19 during the quarter ended
September 30, 1994 to 40 during the quarter ended March 31, 1995.

     Maintenance. Maintenance expenses of $5,650,000 were 17.9% of total
operating expenses. These include all maintenance, labor, parts and supplies
expenses related to the upkeep of the aircraft. Routine maintenance is charged
to maintenance expense as incurred while major engine overhauls and heavy
maintenance checks are accrued each quarter. In the Company's fourth fiscal
quarter ended March 31, 1995, the Company determined, through competitive
bidding, that its accruals for heavy maintenance were unduly high, and a
$500,000 reduction in the accrual was made in this period.

     Promotion and Sales. Promotion and sales expenses totaled $5,293,000 for
the fiscal year ended March 31, 1995 and represented 16.8% of total operating
expenses. These include advertising expenses, telecommunications expenses, wages
and benefits for reservationists and reservations supervision as well as
marketing management and sales personnel. Credit card fees, travel agency
commissions, and computer reservations costs are included in these costs. The
promotion and sales expense per passenger for the year was $19.94, which is
higher than would be normally expected for future Company operations because of
the start-up nature of the airline and the expense required to familiarize the
public with the Company's services.

                                      -17-
<PAGE>
 
     Advertising costs are seasonal as heavier media utilization is planned to
coincide with heavy passenger booking periods. Generally, as new cities are
added to the Company's flight schedule, advertising and marketing promotions are
designed to increase awareness of the Company's new service to create name and
brand awareness.

     General and Administrative. General and administrative expenses totaling
$1,875,000 were 5.9% of total operating expenses and include the wages and
benefits for the Company's executive officers and various other administrative
personnel. Legal and accounting expenses, supplies and other miscellaneous
expenses are also included in this category.

     Depreciation and Amortization. Depreciation and amortization expense of
$248,000 was less than one percent of total operating expenses and includes
depreciation of office equipment, ground station equipment, and other fixed
assets of the Company. Amortization of start-up and route development costs are
not included as these expenses have been expensed as incurred.

     Expenses per ASM. Generally, the Company's expense per ASM declined during
its first fiscal year as service and equipment added contributed to economies of
scale and as the high fixed costs associated with the airline were spread across
a larger base of operation. The average expense per ASM for the year was 8.83c.
The notable exception to the decrease in expense per ASM was the cost associated
with DIA described above, which had an impact upon the Company for the operating
period from February 28, 1995, when DIA opened, through March 31, 1995. The
Company increased its local Denver fares by up to $35 per ticket in March 1995
in response to these and other expected cost increases.

     Expenses per ASM are influenced to a degree by the utilization of aircraft
and by the seating configuration that each airline employs. For example, with
the 108 seat all coach seating configuration selected by the Company on five of
its 737-200 aircraft, the expenses per ASM of the Company are higher by 11% when
compared with the 120 seat alternative used by many carriers.

     Aircraft and traffic servicing expenses will increase with the addition of
new cities; however, the increased existing gate utilization at DIA will reduce
per unit expenses.

     Year ended March 31, 1996. Flight operations expenses of $28,019,000 were
36.7% of total operating expenses and include all expenses related to the
operation of the aircraft including fuel, lease and insurance expenses, pilot
and flight attendant compensation, in-flight catering, crew overnight expenses,
flight dispatch and flight operations administrative expenses.

     Aircraft fuel expenses include both the direct cost of fuel as well as the
related taxes and the cost of delivering fuel into the aircraft. Aircraft fuel
costs of $11,836,000 for 16,746,000 gallons used resulted in an average fuel
cost per gallon during the year ended March 31, 1996 of 70.67c. Fuel consumption
for the year ended March 31, 1996 averaged 806 gallons per block hour but varied
monthly as weather and flight planning changed. Fuel prices during the period
were generally stable but increased slightly in the second calendar quarter of
1996. Fuel expenses for the year ended March 31, 1996 were approximately 4.52c
higher that the average fuel cost per gallon for the year ended March 31, 1995
of 66.15c. The increase is attributable to a slight increase in the cost of fuel
and the fuel tax of 4.3c which became effective October 1, 1995. Assuming the
Company's present nine aircraft operation, a one cent variance in the cost per
gallon of fuel would have a $300,000 annual impact on the Company's expenses.
Fuel prices are subject to change weekly as the Company generally purchases in
advance for the following week's requirements. The Company will reduce its
exposure to fuel price increases to some extent as it leases additional Boeing
737-300 or comparable aircraft that are more fuel efficient than the older
Boeing 737-200 aircraft.

     In August 1993, the United States increased taxes on domestic fuel,
including aviation fuel, by 4.3c per gallon. Airlines were exempt from this tax
increase until October 1, 1995. Effective October 1, 1995, the Company's
suppliers began to charge this tax. The aviation fuel tax included in the total
fuel cost of $11,836,000 was approximately $425,000 for the six months ended
March 31, 1996. The airline industry has proposed an extension of this
exemption. In May 1996, the House of Representatives had approved an additional
seven month extension of the exemption through December 31, 1997. As of June 11,
1996 the Senate had not approved or disapproved the House's recommendation.
Management is

                                      -18-
<PAGE>
 
unable to predict if an extension of the airline industry's exemption will be
approved. The fuel tax increases the Company's annual costs by approximately
$1,290,000, assuming its current nine aircraft fleet and annual consumption of
approximately 30 million gallons of fuel.

     Aircraft lease and insurance expenses, including passenger liability
insurance, totaled $8,506,000 for the year ended March 31, 1966 for the seven
aircraft operated during the year. These expenses can be expected to increase
during fiscal 1997 if the Company leases additional aircraft.

     Pilot and flight attendant compensation totaled $4,025,000, excluding
compensation under the ESOP, for the year ended March 31, 1996. With a scheduled
passenger operation, and with salaried rather than hourly crew compensation, the
Company's expenses for flight operations are largely fixed, with flight catering
expenses a principal exception.

     Aircraft and traffic servicing expenses were $18,487,000 and represented
24.2% of total operating expenses for the year ended March 31,1996 compared to
18.8% of total operating expenses for the year ended March 31, 1995. The
increase as a percentage of total operating expenses is largely attributable to
the increased costs of operating at DIA versus Stapleton. DIA opened on February
28, 1995. The Company operated out of DIA for only one month of the year ended
March 31,1995 and for the entire year ended March 31, 1996. These include all
expenses incurred at the airports as well as station operations administration
and flight operations ground equipment maintenance. Station expenses include
landing fees, facilities rental, station labor and ground handling expenses.

     Maintenance expenses of $11,732,000 were 15.4% of total operating expenses.
These include all maintenance, labor, parts and supplies expenses related to the
upkeep of the aircraft. Routine maintenance is charged to maintenance expense as
incurred while major engine overhauls and heavy maintenance checks are accrued
each quarter.

     Promotion and sales expenses totaled $14,219,000 for the year ended March
31, 1996 and represented 18.6% of total operating expenses. These include
advertising expenses, telecommunications expenses, wages and benefits for
reservationists and reservation supervision as well as marketing management and
sales personnel. Credit card fees, travel agency commissions and computer
reservations costs are included in these costs. The promotion and sales expense
per passenger was $18.75 which is higher than would be normally expected for
future Company operations because of the start-up nature of the airline and the
introductory expense required to familiarize the public with the Company's
services.

     Advertising costs are seasonal as heavier media utilization is planned to
coincide with heavy passenger booking periods. In addition, as new cities are
added to the Company's flight schedule, advertising and marketing promotions are
designed to increase awareness of the Company's new service to create name and
brand awareness. Advertising expenses of $1,619,000 were 2.4% of passenger
revenues for the year ended March 31, 1996, compared to approximately $908,000
or 3.8% of passenger revenues for fiscal year ended March 31, 1995. The Company
expects these costs to continue to decrease as a percentage of revenue.

     General and administrative expenses totaling $3,321,000 were 4.4% of total
operating expenses and include the wages and benefits for the Company's
executive officers and various other administrative personnel. Legal and
accounting expenses, supplies and other miscellaneous expenses are also included
in this category.

     Depreciation and amortization expense of $547,000 was less than one percent
of total operating expenses and includes depreciation of office equipment,
ground station equipment, and other fixed assets of the Company. Amortization of
start-up and route development costs are not included as these expenses have
been expensed as incurred.

     Expense per ASM.  The average expense per ASM for the year ended March 31,
1996 was 9.04c as compared to 8.83c for the year ended March 31, 1995.  The
increase is primarily attributable to the higher operating expenses at DIA as
compared to those at Stapleton.  The Company only operated at DIA for the last
month of its fiscal year 1995.  After the average expense per ASM peaked at
9.53c for the quarter ended September 30, 1995, the average expense per ASM
decreased to 8.50c for the quarter ended March 31, 1996.  The decrease is
attributable to the increase in the number of the Company's aircraft during the
quarter ended December 31, 1995 when the Company added two Boeing 737-300s.  The

                                      -19-
<PAGE>
 
Company was able to add aircraft without adding additional gate positions at DIA
or significantly increasing general and administrative expenses.

LIQUIDITY AND CAPITAL RESOURCES

     The Company's balance sheet reflected cash and cash equivalents and short-
term investments of $7,527,000 at March 31, 1996. At March 31, 1996, total
current assets were $25,797,000 as compared to $25,844,000 total current
liabilities, resulting in working deficit of $47,000.

     Cash used in operating activities for the year ended March 31, 1996 was
$2,489,000. This is attributed primarily to the Company's net loss for the
period, increases in trade receivables, prepaid expenses, deposits to secure
credit card transactions and deposits for aircraft leases, required aircraft
maintenance deposits, and decreases in accrued expenses, offset by increases in
accounts payable, air traffic liability, and accrued maintenance expenses. Cash
used in operating activities improved by $1,737,000 from the year ended March
31, 1995.

     Cash used in investing activities for the year ended March 31, 1995 was
$1,611,000 which consisted of capital expenditures for the five Boeing 737-200s
leased during the year, spare parts, ground equipment, computer equipment,
leasehold improvements and maintenance equipment. Cash used in investing
activities for the year ended March 31, 1996 was $2,234,000. The Company
invested $1,168,000 in short-term investments comprised of certificates of
deposits with maturities of one year or less. The Company had capital
expenditures totaling $1,098,000 consisting of leasehold improvements and
rotables for the two Boeing 737-300s leased in November 1995, expansion of the
Company's reservation system and related leasehold improvements, spare parts,
ground equipment, computer equipment, and maintenance equipment.

     Cash provided by financing activities for the year ended March 31, 1995 was
$9,256,000, primarily reflecting net proceeds from the Company's initial public
offering of common stock and warrants. Cash provided by financing activities was
$7,248,000 for the year ended March 31, 1996, primarily reflecting net proceeds
of $7,282,000 from the Company's secondary public offering sale of common stock.
The Company currently has no lines of credit.

     Five of the Company's Boeing 737-200 aircraft are leased under operating
leases which expire in the year 1997. The leases provide for up to two two-year
renewal terms with no increase in basic rent. Under these leases, the Company
was required to make security deposits and deposits for maintenance of these
leased aircraft. These deposits totaled $625,000 and $6,091,000, respectively,
at March 31, 1996.

     The Company leased two Boeing 737-300 aircraft under operating leases in
November 1995 which expire in the year 2000. The Company was required to make
security deposits and deposits for maintenance of these leased aircraft.
Security and maintenance deposits totaled $1,505,000 and $688,000, respectively,
at March 31, 1996. These aircraft are compliant with Federal Aviation
Administration ("FAA") Stage 3 noise regulations. The Company has issued to each
of the two Boeing 737-300 aircraft lessors a warrant to purchase 100,000 shares
of the Company's Common Stock at a purchase price of $500,000. These warrants,
to the extent not earlier exercised, expire upon the expiration dates of the
aircraft leases.

     In June 1996 the Company leased two additional Boeing 737-200 aircraft
under operating leases which expire in the year 2001. The Company was required
to make security deposits totaling $858,000. The Company is required to make
deposits for maintenance for these leased aircraft which begin in July 1996.
These aircraft will be "hush-kitted" by the lessor at its expense during 1996.
Once "hush-kitted" these aircraft will be compliant with FAA Stage 3 noise
regulations. The Company has issued to the aircraft lessor two warrants to
purchase 70,000 shares each of the Company's common stock at a purchase price of
$503,300 per warrant.

     In June 1996 the Company entered into a lease for a new Boeing 737-300
which is scheduled for delivery in April 1997. The lease term for this aircraft
is eight years from date of delivery with three additional one year renewal
terms at the


                                      -20-
<PAGE>
 
Company's option.  Between June 1996 and February 1997, the Company is required
to make security deposits with respect to this aircraft totaling $726,250.

     In April 1996, the Company completed a private placement of its Common
Stock that resulted in net proceeds of approximately $2,723,000. The net
proceeds will be used principally to lease additional aircraft, subject to
availability.

     In May 1996, the Company notified the warrant holders of the Company's
intent to exercise its redemption rights with respect to the warrants not
exercised on or before June 28, 1996. As of June 14, 1996, 626,060 warrants had
been exercised and the Company had received net proceeds of $3,129,000. If the
remaining 2,043,940 warrants are exercised prior to the June 28, 1996 deadline,
additional proceeds to the Company will be approximately $10,219,000.

     Management is taking steps designed to improve the Company's operating
performance. The Company believes that expansion of service through its Denver
hub is essential for its long-term success. The airport charges at DIA were
increased several times in the months preceding that airport's opening on
February 28, 1995. They have also been increased since the airport opened as
additional charges have been made to the cost allocation formulas used by the
airport. Carriers that are able to utilize their gate positions at DIA with
greater frequency each day can reduce the impact of DIA's relatively high costs.
In September 1995, the Company redeployed some of its aircraft from the
Company's relatively lightly traveled routes in Montana and added service to new
routes to two of Denver's major destinations: Chicago (Midway), Illinois and
Phoenix, Arizona. In November 1995, the Company commenced service from Denver to
Los Angeles, California, Minneapolis-St. Paul, Minnesota, Salt Lake City, Utah,
and San Francisco, California in conjunction with the two Boeing 737-300
aircraft delivered to it in October 1995. These markets have strong local
passenger volumes and represent destinations requested by customers within the
Company's current route cities. These increased flights were accommodated with
the Company's present four gate operation at DIA. The fourth fiscal quarter
ended March 31, 1996 was the first full quarter that the Company's present route
system was in place and the Company's seven aircraft were fully utilized. The
Company had operating income of $833,000 for the quarter ended March 31, 1996
which was its first profitable quarter.

     As of June 1996, the Company serves 15 cities from Denver with nine
aircraft. The Company's goal is to lease a number of additional aircraft to
serve additional cities from Denver. The Company believes that such a route
system would facilitate a greater volume of connecting traffic as well as a
stable base of local traffic and offset the impact of higher DIA-related
operating costs through more efficient gate utilization.

     In late October 1995, a competing low fare carrier, headquartered in
Denver, discontinued its flight operations. This carrier handled approximately
2% of the traffic at DIA as of the quarter ended June 30, 1995. With
approximately one half of the carrier's destination cities also served (or to be
served) by the Company, management believes that traffic on these routes
improved in the short-term as an outgrowth of that carrier's service
termination.

     The Company is exploring various means to reduce expenses. These include
use of a ticketless reservations system, a reduction in credit card fees, and an
in-house revenue accounting system. The Company believes that it can reduce its
airport operating expenses at certain cities by performing its own "above wing"
operations (including passenger check-in at ticket counters, concourse gate
operations, cabin cleaning and baggage services) rather than continuing to
contract out these services. The Company commenced performing such operations at
DIA in April 1996 and at Los Angeles International Airport in June 1996. A
changeover to the Company's handling of these activities at Chicago/Midway is
expected to be completed by July 1996, at which time the Company will be doing
its own "above wing" operations at eight of the 16 airports it serves.

     The proceeds from the private placement completed in April 1996 and the
conversion of the warrants in June 1996 have provided additional working capital
for the Company and, subject to aircraft availability, will enable it to further
expand its operations through the leasing of additional aircraft. The Company's
suppliers currently provide goods, services and operating equipment on open
credit terms. If such terms were modified to require immediate cash payments,
the Company's cash position would be materially and adversely affected. The
expansion of the Company's operations will entail the hiring of additional
employees to staff flight and ground operations in its new markets and
significant initial costs such as deposits for airport and aircraft leases.
Because of the expansion of the Company's business and the competitiveness of
the airline

industry, which often requires quick reaction by management to changes in market
conditions, the Company may require additional capital to maintain or further
expand its business.

NOTES TO FINANCIAL STATEMENTS

MARCH 31, 1996

- ------------------------------------------------------------------------------- 

(1)  NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     NATURE OF BUSINESS

     Frontier Airlines, Inc. (the Company) was incorporated in the State of
     Colorado on February 8, 1994 and is engaged in the business of operating a
     commercial airline based in Denver, Colorado which currently serves
     selected midwestern and western cities. The Company commenced airline
     operations on July 5, 1994.

     The airline industry is highly competitive primarily due to the effects of
     the Airline Deregulation Act of 1978, which has substantially eliminated
     government authority to regulate domestic routes and fares and has
     increased the ability of airlines to compete with respect to flight
     frequencies and fares.

     The airline industry is also characterized by low gross profit margins,
     with fixed costs that are high in relation to revenues. Accordingly, a
     shortfall from expected revenue levels can have a material adverse effect
     on profitability, including the Company's. The Company's connecting hub is
     located at Denver International Airport (DIA). DIA opened in March 1995.
     Financed through revenue bonds, DIA depends on landing fees, gate rentals
     and other income from airlines, the traveling public and others to pay debt
     service and support operations. Management believes that the Company's
     operating costs at DIA will substantially exceed those that other airlines
     incur at hub airports in other cities.

     The airline industry is significantly affected by general economic
     conditions. Because a substantial portion of business and personal airline
     travel is discretionary, the industry tends to experience severe adverse
     financial results during general economic downturns. The Company's business
     also is seasonal, which can affect the Company's results of operations from
     quarter to quarter.

     Fuel is a major component of operating expense for all airlines. Both the
     cost and availability of fuel are subject to many economic and political
     factors and events occurring throughout the world. The future cost and
     availability of fuel to the Company cannot be predicted, and substantial
     sustained price increases or the unavailability of adequate fuel supplies
     could have a material adverse effect on the Company's operations and
     profitability.

     PREPARATION OF FINANCIAL STATEMENTS

     The preparation of financial statmeents 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.

     CASH AND CASH EQUIVALENTS

     For financial statement purposes, the Company considers cash and short-term
     investments with an original maturity of three months or less to be cash
     equivalents.

(1)  NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
     (CONTINUED)


    SHORT-TERM INVESTMENTS

    Short-term investments are comprised of certificates of deposit and are
    carried at cost, which management believes approximates market value.
    Maturities are for one year or less and the Company intends to hold short-
    term investments to maturity.

    RESTRICTED INVESTMENTS

    Restricted investments include certificates of deposit and government
    treasury bills which secure certain letters of credit issued primarily to
    companies which process credit card sale transactions and certain airport
    authorities.  Restricted investments are carried at cost, which management
    believes approximates market value.  Maturities are for one year or less and
    the Company intends to hold restricted investments until maturity.

    INVENTORIES

    Inventories consist of expendable parts, supplies and aircraft fuel and are
    stated at the lower of cost or market.  Inventories are accounted for on a
    first-in, first-out basis and are charged to expense as they are used.

    Under the terms of the aircraft lease agreements for the five Boeing 737-200
    aircraft discussed in note 5, the lessor has consigned expendable parts and
    supplies to the Company.  The Company has also entered into an agreement
    with a supplier for consigned parts and supplies for the two Boeing 737-300
    aircraft.  The Company is required to pay a monthly consignment fee, based
    on the value of the consigned parts, and to replenish any such parts when
    used with a like part.  Expendable parts and supplies are charged to expense
    as they are used.  At March 31, 1996, the Company held consigned parts and
    supplies in the amount of approximately $4,565,059, which are not included
    in the Company's balance sheet.

    PROPERTY AND EQUIPMENT

    Property and equipment are carried at cost.  Major additions, betterments
    and renewals are capitalized.  Depreciation and amortization is provided for
    on a straight-line basis to estimated residual values over estimated
    depreciable lives as follows:

       Flight equipment                        3 years
       Improvements to leased aircraft         Life of improvements or term of
                                               lease,whichever is less
       Ground property, equipment, and
         leasehold improvements                3-5 years or term of lease

    Assets utilized under capital leases are amortized over the lesser of the
    lease term or the estimated useful life of the asset using the straight-line
    method.  Amortization of capital leases is included in depreciation expense.

(1) NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
    (CONTINUED)

    Routine maintenance and repairs are charged to operations as incurred.
    Costs of major improvements are capitalized and expensed over the period of
    expected benefit.  Additionally, a provision is made for the estimated cost
    of scheduled major overhauls required to be performed on leased aircraft
    under the provisions of the aircraft lease agreements.  Accrued maintenance
    expense expected to be incurred beyond one year is classified as long-term.

    REVENUE RECOGNITION

    Passenger, cargo, and other revenues are recognized when the transportation
    is provided or after the tickets expire.  Revenues which have been deferred
    are included in the accompanying balance sheet as air traffic liability.

    PASSENGER TRAFFIC COMMISSIONS AND RELATED EXPENSES

    Passenger traffic commissions and related expenses are expensed when the
    transportation is provided and the related revenue is recognized.  Passenger
    traffic commissions and related expenses not yet recognized are included as
    a prepaid expense.

    FREQUENT FLYER AWARDS

    The Company maintains a frequent travel award program that provides awards
    to program members based on accumulated mileage.  The estimated cost of
    providing the free travel is recognized as a liability and charged to
    operations as program members accumulate mileage.  The Company also allows
    program members to accumulate mileage on Continental Airline's OnePass
    frequent flyer program, instead of the Company's program.  The cost of
    providing mileage on the OnePass program is based on an agreed upon rate per
    mileage credit, which is paid to Continental Airlines on a monthly basis.

    LOSS PER COMMON SHARE

    Loss per common share is computed based on the weighted average number of
    common shares and, if dilutive, common stock equivalent shares (options and
    warrants) outstanding during the respective periods.

    INCOME TAXES

    The Company accounts for income taxes using the asset and liability method
    prescribed by Statement of Financial Accounting Standards No. 109,
    Accounting for Income Taxes.   Under the asset and liability 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
    tax bases of the existing assets and liabilities.  A valuation allowance is
    provided to the extent that the realizability of net deferred tax assets is
    judged by management to be unlikely.  The effect on deferred taxes from a
    change in tax rates is recognized in income in the period that includes the
    enactment date.

      those employees covered by a collective bargaining agreement that does not
      provide for participation in the ESOP. Company contributions to the ESOP
      are discretionary and vary from year to year. In order for an employee to
      receive an allocation of company common stock from the ESOP that employee
      must be employed on the last day of the ESOP's plan year, with certain
      exceptions. The Company's annual contribution to the ESOP, if any, will be
      allocated among the eligible employees of the Company as of the end of
      each plan year in proportion to the relative compensation (as defined in
      the ESOP) earned that plan year by each of the eligible employees. The
      ESOP does not provide for contributions by participating employees.
      Employees will vest in contributions made to the ESOP based upon their
      years of service with the Company. A year of service is an ESOP plan year
      during which an employee has at least 1,000 hours of service. Vesting
      generally occurs at the rate of 20% per year, beginning after the first
      year of service, so that a participating employee will be fully vested
      after five years of service. Distributions from the ESOP will not be made
      to employees during employment. However, upon termination of employment
      with the Company, each employee will be entitled to receive the vested
      portion of his or her account balance.

      The initial Company contribution to the ESOP was made on June 22, 1995 and
      consisted of 137,340 shares of Common Stock, of which 27,468 shares relate
      to the plan year ended March 31, 1995 and 109,872 shares relate to the
      period from April 1, 1995 to December 31, 1995. The Company recognized
      compensation expense during the year ended March 31, 1996 of $721,000
      related to its contribution to the ESOP.

(10)  CONCENTRATION OF CREDIT RISK

      The Company does not believe it is subject to any significant
      concentration of credit risk relating to trade receivables. At March 31,
      1996, over 91% of the Company's trade receivables relate to tickets sold
      to individual passengers through the use of major credit cards, travel
      agencies approved by the Airlines Reporting Corporation or tickets sold by
      other airlines and used by passengers on Company flights. These
      receivables are short-term, generally being settled shortly after sale or
      in the month following ticket usage.

(11)  COMMITMENTS AND CONTINGENCIES
                                                                                
      The Company is party to legal proceedings and claims which arise during
      the ordinary course of business. In the opinion of management, the
      ultimate outcome of these matters will not have a material adverse effect
      of the Company's financial position or results of operations.

(12) SUBSEQUENT EVENTS

     On April 16, 1996, the Company sold 678,733 shares of its common stock, no
     par value, through a private placement to four institutional investors.
     Gross proceeds to the Company from the transactions were $3,000,000, of
     which the Company received net proceeds of $2,723,000.

     Subsequent to March 31, 1996 and through June 14, 1996, the Company was
     required to secure additional letter of credits totaling $2,087,000 in
     connection with credit card and travel agent cash sales transactions,
     thereby requiring an additional restriction on cash for the same amount.

     As discussed in note 7, subsequent to March 31, 1996, the Company notified
     the holders of 2,670,000 warrants to purchase the Company's common stock
     of the Company's intent to redeem the warrants at $.05 per warrant unless
     the warrants are exercised on or before June 28, 1996. As of June 14, 1996,
     626,060 of the warrants had been exercised with net proceeds to the Company
     of $3,129,300.

     In May and June 1996 the Company entered into operating lease agreements to
     lease two Boeing 737-200 aircraft with lease terms expiring in the year
     2001. These two aircraft were delivered to the Company and placed in
     scheduled service in June 1996. Lease deposits of $858,000 were paid by the
     Company in connection with the two leased aircraft.

     The Company has entered into an operating lease agreement to lease a new
     Boeing 737-300 aircraft with delivery expected in April 1997. This lease is
     for a period of eight years from date of delivery with three additional
     renewal periods at the option of the Company. Between June 1996 and
     February 1997, the Company is required to make security deposits with
     respect to this aircraft totaling $726,250.

THIS AGREEMENT is made as of the 20th day of October, 1995 between:-

(1)   GPA II Limited, a company incorporated under the laws of Ireland whose
      registered office is at GPA House, Shannon, Co. Clare, Ireland ("Lessor");
      and

      WHEREAS:  Lessor wishes to lease to Lessee and Lessee is willing to lease
      from Lessor the Aircraft on the terms of this Agreement.

      It is proposed that, at the Adjustment Date, the then existing financing

      that the security granted in favour of the Trustee on behalf of the Banks
      will be released.  The Lessor and the Lessee agree to amend and modify
      this Agreement at the Adjustment Date to reflect this change.

      IT IS AGREED as follows:-

1.   INTERPRETATION

1.1  DEFINITIONS

      In this Agreement the following expressions have the meanings set out
      opposite:-

      Adjustment Date               a date which shall be determined by Lessor
                                    and shall be notified by Lessor to Lessee
                                    promptly following such determination.

                                    "After-Tax Basis" to or for the benefit of
                                    any Person (including any amount payable

                                    respect to the receipt or accrual by it of
                                    such amount (and assuming that such Person
                                    is subject to (i) United States Federal

      the Aircraft (other than because of any default of Lessor in the
      performance of its obligations under that agreement unless the default
      arises from any act or omission of Lessee);

(c)   any Excusable Delay; or

(d)   notification of any defect or non-conformity pursuant to Clause 4.5;

      Lessor delays in the delivery of, or fails to deliver, the Aircraft under
      this Agreement:-

      (i)   Lessor will not be responsible for any losses, including loss of
            profit, costs or expenses arising from or in connection with the
            delay or failure suffered or incurred by Lessee;

      (ii)  subject to Clause 4.5, Lessee will not be entitled to terminate this
            Agreement or to reject the Aircraft when tendered for delivery by
            Lessor, on the grounds of any such delay;

                                      25
<PAGE>
 
      (iii) in the case of termination of a purchase agreement, Lessor may at
            any time after the termination terminate this Agreement; and

      (iv)  upon any such termination or termination pursuant to Clause 4.5
            neither Lessor nor Lessee will have any further obligation to the
            other under this Agreement other than as expressly set out in this
            Agreement, except that Lessor will repay to Lessee the Deposit and
            shall return the warrant certificate representing the Warrant.

4.4   Licenses: Lessee will at its expense obtain all licenses, permits and
      approvals which may be necessary to export the Aircraft from the Delivery
      Location. Lessor will furnish such data and information as may be
      reasonably requested by Lessee in connection with obtaining any such
      license, permit or approval.

4.5   Inspection: Prior to the Delivery Date, subject to any applicable purchase
      or lease agreement, Lessor will give Lessee an opportunity:-

(a)   to inspect the Aircraft at the Delivery Location; and

(b)   to assign up to 2 representatives to participate as observers in a
      demonstration flight to demonstrate the condition of the Aircraft.

      If Lessee notifies Lessor promptly prior to the Delivery Date of any
      defect or non-conformity with Schedule 1 observed during the inspection or
      demonstration flight, Lessor will correct or procure the correction of the
      defect or non-conformity as promptly as practicable (except to the extent
      otherwise agreed or to the extent in the opinion of Lessor it is
      impracticable or prohibitively expensive to do so).  Subject to Clause
      4.3, Lessor may postpone the Delivery Date in such a case to the date
      which Lessor notifies Lessee that the defect or non-conformity has been
      rectified.  Lessee will be entitled to terminate this Agreement if Lessor
      notifies it that Lessor does not intend to correct the defect or non-
      conformity.

4.6   Indemnity: Lessee will indemnify and hold harmless the Indemnitees from
      and against all Claims (as defined in Clause 10) arising from death or
      injury to any observer or any employee of Lessee in connection with any
      demonstration flight or inspection of the Aircraft by Lessee.

5.    PAYMENTS

5.1   Deposit: Lessee shall pay to Lessor a Deposit in the amount of $752,500 in
      accordance with the following:-

(a)   $215,000 the receipt of which is acknowledged;

(b)   $322,500 payable on the date of this Agreement; and

(c)   $215,000 not less than two days prior to the Delivery Date.

                                      26
<PAGE>
 
5.2   Rental Periods: The first Rental Period will commence on the Delivery Date
      and each subsequent Rental Period will commence on the date succeeding the
      last day of the previous Rental Period. Each Rental Period will end on the
      date immediately preceding the calendar day in the next month numerically
      corresponding to the Delivery Date except that:-

(a)   if there is no such numerically corresponding day in that month, it will
      end on the last day of that month; and

(b)   if a Rental Period would otherwise overrun the Expiry Date, it will end on
      the Expiry Date.

5.3   Rent:

(a)   Determination: Lessee will pay to Lessor or its order on each Rent Date
      Rent in advance in the amount of $215,000 provided always that if on the
      day which is two Business Days prior to the Delivery date (the "Quotation
      Date") (I) Actual LIBOR is in excess of Assumed LIBOR, the said sum of
      $215,000 shall be increased by $130 for each basis point by which, on the
      Quotation Date, Actual LIBOR exceeds Assumed LIBOR and (ii) in the event
      that Actual LIBOR falls below Assumed LIBOR, the said sum of $215,000
      shall be decreased by $130 for each basis point by which, on the Quotation
      Date, Actual LIBOR falls below Assumed LIBOR.

(b)   Reference Definition: For the purposes of this Clause 5.3 "Assumed LIBOR"
      means 6.2%; and "Actual LIBOR" means the rate of interest per annum at
      which at or about 11:00 a.m. (London time) on the Quotation Date deposits
      in Dollars are offered for a six month period on the Reuters "LIBO" page
      or, if on the Quotation Date the Reuters "LIBO" page is not available or
      does not display rates for the required period, the "Telerate" page.

(c)   Time of Payment: Payment must be initiated adequately in advance of the
      Rent Date to ensure that Lessor receives credit for the payment on the
      Rent Date.  If a Rental Period begins on a non-Business Day, the Rent
      payable in respect of that Rental Period shall be paid on the Business Day
      immediately preceding the date on which such Rental Period commences.

(d)   Abatement: The Lessor hereby agrees that in respect of the first Rental
      Period (the Rent for which shall be deemed to accrue pro-rata on a daily
      basis throughout such period) the Rent shall be abated for the period of
      10 days immediately following the Delivery Date or until the Aircraft
      enters commercial airlines service, whichever occurs first.

                                      27

5.4  Maintenance Reserves:

(a)   Amount: Lessee will further pay to Lessor Maintenance Reserves in relation
      to each Rental Period (including without limitation the last Rental Period
      of the Term) no later than the 10th day following the end of that Rental
      Period as follows:-

      (i)   in respect of the Airframe, $77 for each Flight Hour operated by the
            Aircraft during that Rental Period ("Airframe Maintenance
            Reserves"); and

      (ii)  in respect of each Engine, $74 for each Flight Hour operated by that
            Engine during that Rental Period ("Engine Maintenance Reserves");
            and

      (iii) in respect of the life-limited Parts ("LLP") for each Engine, $21
            for each Flight Hour operated by that Engine during the Rental
            Period ("Engine LLP Maintenance Reserves"); and

      (iv)  in respect of the Landing Gear, $12 for each Flight Hour operated by
            the Landing Gear during that Rental Period ("Landing Gear
            Maintenance Reserves"); and

(b)   Adjustment: The Maintenance Reserves shall escalate at a rate of three per
      cent (3%), compounded annually, commencing on the first annual anniversary
      of the Delivery Date. Lessor and Lessee hereby acknowledge that the
      Maintenance Reserves are based on the assumption that the operation of the
      Aircraft during the Term will, on average, be not less than two Flight
      Hours for each Cycle). In the event that the foregoing assumption proves
      to be incorrect at any time during the Term based upon Lessee's actual
      operating experience during the previous twelve (12) months, and the hour
      cycle ratio differs from such assumption by more than 0.1 during such
      twelve (12) month period, Lessor shall have the right, upon written notice
      to Lessee, to adjust the Engine Maintenance Reserves and/or the Engine LLP
      Maintenance Reserves in the case of a decrease in the ratio and Lessor,
      upon written request from Lessee, will make an adjustment in the case of
      an increase in the ratio. Any such adjustment shall be based upon the
      following table:

<TABLE>   ---------------------------------------------------------- 
          PER ENGINE HOUR/CYCLE
          ----------------------------------------------------------
          <S>                                     <C>    <C>    <C>
                                                  1.5    2.0    2.5
          ----------------------------------------------------------
          Engine Maintenance Reserves             $ 78*  $ 74*  $ 70*
          ----------------------------------------------------------
          Engine LLP Maintenance Reserve Rates    $ 27*  $ 21*  $ 16*
          ----------------------------------------------------------
</TABLE>

      (* denotes that the figure is to be escalated at a rate of three percent
      (3%) compounded annually, commencing on the first annual anniversary of
      the Delivery Date.)

      Actual hour to cycle ratios may fall outside of the amount identified in
      the table.  In such case, the actual values shall be determined by
      extrapolating the closest observed intervals in the table.  (For example,
      an hour to cycle ratio of 1.7:1 falls in between 1.5:1 and

                                      28
<PAGE>
 
      2.0:1 resulting in the extrapolated values of $76.40 for Engine
      Maintenance Reserves Rates and $24.60 for Engine LLP Maintenance
      Reserves.)

      In the event that the Agreed Maintenance Program is materially revised,
      Lessor may make such adjustment as Lessor determines is necessary in its
      reasonable discretion to maintain the Reserves at levels which accurately
      reflect the costs associated with obtaining maintenance services at
      prevailing industry rates.  Each such notice shall specify the revised
      Maintenance Reserves and the effective date of such revision.  Lessee
      agrees to advise Lessor, in writing, promptly following the occurrence of
      any circumstances or events which would result in the foregoing
      assumptions becoming incorrect at any time during the Term.

5.5   Payments: All payments by Lessee to Lessor under this Agreement will be
      made for value on the due date in Dollars and in same day funds settled
      through the New York Clearing House System or such other funds as may for
      the time being be customary for the settlement in New York City of
      international payments in Dollars by telegraphic transfer to Chase
      Manhattan Bank N.A., 35th Floor, 1 Chase Manhattan Plaza, New York, NY,
      10081; CHASUS 33; for the account of Bank of NT Butterfield, 65 Front
      Street, Hamilton, Bermuda, Account Number 001-1-067808 for credit to GPA
      DAF Bermuda Collection Account, Account Number 82757DD0101 or to such
      other account as Lessor may advise Lessee in writing.  Lessor will notify
      Lessee of the details of the new account to which payments are to be made
      under this Agreement, after the Adjustment Date, as soon as practical
      after the Adjustment Date.

5.6   Gross-up:

(a)   All payments by Lessee under or in connection with this Agreement or the
      other Operative Documents will be made without set-off or counterclaim,
      free and clear of and without deduction for or on account of all Taxes;

(b)   all Taxes (other than Lessor Taxes) in respect of payments under this
      Agreement or the other Operative Documents shall be for the account of and
      will be paid by Lessee for its own account prior to the date on which
      penalties apply; and

(c)   if Lessee is compelled by law to make payment subject to any Tax and
      Lessor does not actually receive for its own benefit on the due date a net
      amount on an After-Tax Basis equal to the full amount provided for under
      this Agreement, Lessee will pay all necessary additional amounts to ensure
      receipt by Lessor of the full amount on an After-Tax Basis so provided
      for.

5.7   Taxation: Lessee will on demand pay and indemnify Lessor against all Taxes
      (other than Lessor Taxes) levied or imposed against or upon Lessor, Owner
      or Lessee and relating to or attributable to Lessee, this Agreement or the
      other Operative Documents (except for the Warrant and the side letter
      dated as of  October 20, 1995 specifically relating 

                                      29
<PAGE>
 
      thereto but save in so far as any indemnity by Lessee in respect of Taxes
      is specifically provided for therein) or the Aircraft directly or
      indirectly in connection with the importation, exportation, registration,
      ownership, leasing, sub-leasing, purchase, delivery, possession, use,
      operation, repair, maintenance, overhaul, transportation, landing,
      storage, presence or redelivery of the Aircraft or any part thereof or any
      rent, receipts, insurance proceeds, income or other amounts arising
      therefrom.

5.8   Value Added Tax:

(a)   For the purposes of this sub-clause:-

      (i)   "VAT" means value added tax and any sales or turnover tax,
            imposition or levy of a like nature;

      (ii)  "supply" includes anything on which VAT is chargeable;

(b)   Lessee will pay to Lessor on an After-Tax Basis the amount of any VAT
      chargeable in respect of any supply for VAT purposes under this Agreement;
      and

(c)   each amount stated as payable by Lessee under this Agreement is exclusive
      of VAT (if any) and is accordingly to be construed as a reference to that
      amount plus any VAT in respect of it.

5.9   Information: If Lessee is required by any applicable Law, or by any third
      party, to deliver any report or return in connection with any Taxes,
      Lessee will complete the same in a manner satisfactory to Lessor and in
      particular will state therein that Lessee is exclusively responsible for
      the use and operation of the Aircraft and for any Taxes arising therefrom,
      and Lessee will, on request supply a copy of the report or return to
      Lessor.

5.10  Taxation of Indemnity Payments:

(a)   If and to the extent that any sums payable to Lessor by Lessee under this
      Agreement by way of indemnity are insufficient, by reason of any Taxes
      payable in respect of those sums, for Lessor to discharge the
      corresponding liability to the relevant third party (including any
      taxation authority), or to reimburse Lessor for the cost incurred by it to
      a third party (including any taxation authority) Lessee will pay to Lessor
      on an After-Tax Basis such sum as will after the tax liability has been
      fully satisfied leave Lessor with the same amount as it would have been
      entitled to receive in the absence of that liability together with
      interest on the amount of the deficit at the rate of interest stated in
      Clause 5.11 in respect of the period commencing on the date on which the
      payment of taxation is finally due until payment by Lessee (both before
      and after judgment); and

                                      30
<PAGE>
 
(b)   if and to the extent that any sums constituting (directly or indirectly)
      an indemnity to Lessor but paid by Lessee to any person other than Lessor
      are treated as taxable in the hands of Lessor, Lessee will pay to Lessor
      such sum as will after the tax liability has been fully satisfied
      indemnify Lessor on an After-Tax Basis to the same extent as it would have
      been indemnified in the absence of such liability together with interest
      on the amount payable by Lessee under this sub-clause at the rate of
      interest stated in Clause 5.11 in respect of the period commencing on the
      date on which the payment of taxation is finally due until payment by
      Lessee (both before and after judgment).

5.11  Default Interest: If Lessee fails to pay any amount payable under this
      Agreement on the due date, Lessee will pay on demand from time to time to
      Lessor interest (both before and after judgment) on that amount, from the
      due date to the date of payment in full by Lessee to Lessor, at the rate
      calculated by Lessor to be 1.5 percent per month, but in no event
      exceeding the highest rate permitted by Law.  All such interest will be
      compounded monthly and calculated on the basis of the actual number of
      days elapsed and a 360 day year.

5.12  Contest: If Lessee disputes the payment of any Taxes payable by Lessor for
      which Lessee is responsible under this Agreement, Lessor will consider
      with Lessee the taking of such action as Lessee may reasonably request at
      Lessee's expense to contest that payment but will not be obliged to take
      any such action:-

(a)   which Lessor considers in its sole discretion may prejudice it; or

(b)   which Lessor considers does not have a reasonable prospect of success; or

(c)   for which Lessee has not made adequate provision to the satisfaction of
      Lessor in respect of the expense concerned.

5.13  Net Lease: This Agreement is a net lease.  Lessee's obligations under this
      Agreement are absolute and unconditional irrespective of any contingency
      whatsoever including (but not limited to):-

(a)   any right of set-off, counterclaim, recoupment, defense or other right
      which either party to this Agreement may have against the other;

(b)   any unavailability of the Aircraft for any reason, including, but not
      limited to, a requisition of the Aircraft or any prohibition or
      interruption of or interference with or other restriction against Lessee's
      use, operation or possession of the Aircraft;

(c)   any lack or invalidity of title or any other defect in title,
      airworthiness, merchantability, fitness for any purpose, condition,
      design, or operation of any kind or nature of the Aircraft for any
      particular use or trade, or for registration or documentation under the
      laws of any relevant jurisdiction, or any Event of Loss in respect of or
      any damage to the Aircraft;

                                      31
<PAGE>
 
(d)   any insolvency, bankruptcy, reorganization, arrangement, readjustment of
      debt, dissolution, liquidation or similar proceedings by or against Lessor
      or Lessee;

(e)   any invalidity or unenforceability or lack of due authorization of, or
      other defect in, this Agreement;

(f)   and Security Interests with respect to the Aircraft or Taxes; and/or

(g)   any other cause which but for this provision would or might otherwise have
      the effect of terminating or in any way affecting any obligation of Lessee
      under this Agreement.

5.14  Security

(a)   To the fullest extent permitted by Law and by way of continuing security
      Lessee as sole beneficial owner charges the Deposit and the Maintenance
      Reserves and all rights of Lessee to payment thereof and the debt
      represented thereby (the "Charged Monies") to Lessor by way of first fixed
      charge as security for Lessee's obligations and liabilities under this
      Agreement and the Other Agreements (the "Secured Liabilities").  Except as
      expressly permitted under this Agreement, Lessee will not be entitled to
      payment of the Charged Monies.  Lessee will not assign, transfer or
      otherwise dispose of all or part of its rights in the Charged Monies and
      it will enter into any additional documents and instruments necessary or
      advisable to evidence, create or perfect Lessor's rights to the Charged
      Monies;

(b)   If Lessee fails to comply with any provision of this Agreement or any
      Event of Default has occurred and is continuing, in addition to all rights
      and remedies accorded to Lessor elsewhere in this Agreement and under Law
      as a secured party in respect of the Charged Monies, Lessor may
      immediately or at any time thereafter, without prior notice to Lessee:-

      (i)   set-off all or any part of the Secured Liabilities against the
            liabilities of Lessor in respect of the Charged Monies;  or

      (ii)  apply or appropriate the Charged Monies in or towards the payment or
            discharge of the Secured Liabilities in such order as Lessor sees
            fit; and

(c)   If Lessor has exercised the set-off described in sub-clause (b) above,
      Lessee shall, following a demand in writing from Lessor, restore the
      Charged Monies to the level at which they stood immediately prior to such
      set-off.

 6.   MANUFACTURER'S WARRANTIES

6.1   Assignment: Notwithstanding this Agreement, Lessor will remain entitled to
      the benefit of each warranty, express or implied, with respect to the
      Aircraft, any Engine or Part so far as concerns any manufacturer, vendor,
      subcontractor or supplier. Except to the extent Lessor otherwise directs,
      Lessor hereby authorizes Lessee to pursue any claim thereunder in relation
      to defects affecting the Aircraft, any Engine or Part and Lessee 

                                      32
<PAGE>
 
      agrees diligently to pursue any such claim which arises at its own cost.
      Lessee will notify Lessor promptly upon becoming aware of any such claim.

6.2   Proceeds: Except to the extent Lessor otherwise agrees in a particular
      case, all proceeds of any such claim will be paid directly to Lessor but
      if and to the extent that such claim relates:-

(a)   to defects affecting the Aircraft which Lessee has rectified; or

(b)   to compensation for loss of use of the Aircraft, an Engine or any Part
      during the Term; and

      provided no Default has occurred and is continuing the proceeds will be
      paid to Lessee by Lessor but in the case of (a) above only on receipt of
      evidence satisfactory to Lessor that Lessee has rectified the relevant
      defect.

6.3   Parts: Except to the extent Lessor otherwise agrees in a particular case,
      Lessee will procure that all engines, components, furnishings or equipment
      provided by the manufacturer, vendor, subcontractor or supplier in
      replacement of a defective Engine or Part pursuant to the terms of any
      warranty will be installed promptly by Lessee and that title thereto free
      of Security Interests vests in Lessor.  On installation each part will be
      deemed to be a Part.  In the case of a Replacement Engine, Lessee will
      satisfy and perform each of the conditions and covenants set forth in
      Clause 11.1(c), and upon satisfaction of such conditions, such Replacement
      Engine will be deemed an "Engine" for all purposes of this Agreement.

6.4   Agreement: To the extent any warranties relating to the Aircraft are made
      available under an agreement between any manufacturer, vendor,
      subcontractor or supplier and Lessee, this Clause 6 is subject to that
      agreement.  However Lessee will:-

(a)   pay the proceeds of any claim thereunder to Lessor to be applied pursuant
      to Clause 6.2 and pending such payment will hold the claim and the
      proceeds on trust for Lessor; and

(b)   Lessee will take all such steps as are necessary at the end of the Term to
      ensure the benefit of any of those warranties which have not expired are
      vested in Lessor.

7.    LESSOR'S COVENANTS

7.1   Quiet Enjoyment: Lessor will not interfere with the quiet use, possession
      and enjoyment of the Aircraft by Lessee but the exercise by Lessor of its
      rights under or in connection with this Agreement will not constitute such
      an interference.  Lessor undertakes to deliver to Lessee on or promptly
      after the Delivery Date a letter of quiet enjoyment addressed to Lessee by
      the Owner in the form already notified by Lessor to Lessee prior to the
      date hereof.

7.2   Release of Maintenance Reserves: Provided no Default has occurred and is
      continuing Lessor will release funds to Lessee from the Maintenance
      Reserves respecting 

                                      33
<PAGE>
 
      maintenance work performed upon submission by Lessee to Lessor within 6
      months of the commencement of that maintenance and before the Expiry Date
      of an invoice and supporting documentation reasonably satisfactory to
      Lessor evidencing:-

(a)   with respect to the Airframe, the completion, in accordance with this
      Agreement, of those items of maintenance characterized by the
      Manufacturer's maintenance planning document and best industry practice as
      "D" Check and/or individual structural inspections having an interval of
      not less than 20,000 Flight Hours or 6 years for the Aircraft (but not
      including repairs arising as the result of operational or maintenance
      mishandling), the lesser of (i) the amount of that invoice and (ii) the
      amount equal to the aggregate amount of Airframe Maintenance Reserves paid
      under this Agreement at the time of commencement of that maintenance less
      the aggregate amount previously released by Lessor under this sub-clause;

(b)   with respect to any Engine, the performance, in accordance with this
      Agreement, of all shop visits requiring engine disassembly (other than (i)
      repairs arising as a result of foreign object damage or operational or
      maintenance mishandling and/or (ii) removal, installation, maintenance and
      repair of Quick Engine Change ("QEC") kits), the lesser of (i) the amount
      of that invoice and (ii) the amount equal to the aggregate amount of
      Engine Maintenance Reserves paid in respect of that Engine under this
      Agreement at the time of commencement of that maintenance less the

                                      43
<PAGE>
 
(a)   ensure that, except as permitted by this Agreement, no engine or part is
      installed on the Aircraft unless:-

      (i)   in the case of an engine, it is an engine of the same model as, or
            an improved or advanced version of the Engine it replaces, which is
            in the same or better operating condition, has substantially similar
            hours available until the next scheduled checks, inspections,
            overhauls and shop visits and has the same or greater value and
            utility as the replaced Engine;

      (ii)  in the case of a part, it is in as good operating condition, has
            substantially similar hours available until the next scheduled
            checks, inspections, overhauls and shop visits, is of the same or a
            more advanced make and model and is of the same interchangeable
            modification status as the replaced Part;

      (iii) in the case of a part, it has become and remains the property of
            Owner free from Security Interests and on installation on the
            Aircraft will without further act be subject to the Head Lease and
            this Agreement; and

      (iv)  in each case, Lessee has full details as to its source and
            maintenance records;

(b)   if no Default has occurred which is continuing, be entitled to install any
      engine or part on the Aircraft by way of replacement notwithstanding
      Clause 8.13(a) if:-

      (i)   there is not available to Lessee at the time and in the place that
            that engine or part is required to be installed on the Aircraft, a
            replacement engine or, as the case may be, part complying with the
            requirements of Clause 8.13(a);

      (ii)  it would result in an unreasonable disruption of the operation of
            the Aircraft and/or the business of Lessee to ground the Aircraft
            until an engine or part, as the case may be, complying with Clause
            8.13(a) becomes available for installation on the Aircraft; and

      (iii) as soon as practicable after installation of the same on the
            Aircraft but, in any event, no later than the Expiry Date, Lessee
            removes any such engine or part and replaces it with the Engine or
            Part replaced by it or by an engine or part, as the case may be,
            complying with Clause 8.13(a).

8.14  Non-Installed Engines and Parts: Lessee will:-

(a)   ensure that any Engine or Part which is not installed on the Aircraft (or
      any other aircraft as permitted by this Agreement) is, except as expressly
      permitted by this Agreement, properly and safely stored, and kept free
      from Security Interests;

(b)   notify Lessor whenever any Engine is removed from the Aircraft and, from
      time to time, on request procure that any person to whom possession of an
      Engine is given acknowledges in writing to Lessor, in form and substance
      satisfactory to Lessor, that it 

                                      44
<PAGE>
 
      will respect the interests of Owner and Lessor in the Engine and will not
      seek to exercise any rights whatsoever in relation to it;

(c)   (notwithstanding the foregoing provisions of this sub-clause), be
      permitted, if no Default has occurred and is continuing, to install any
      Engine or Part on an aircraft, or in the case of a Part on an engine:-

      (i)   owned and operated by Lessee free from Security Interests;  or

      (ii)  leased or hired to Lessee pursuant to a lease or conditional sale
            agreement on a long-term basis and on terms whereby Lessee has full
            operational control of that aircraft or engine;  or

      (iii) acquired by Lessee and/or financed or refinanced, and operated by
            Lessee, on terms that ownership of that aircraft or engine, as the
            case may be, pursuant to a lease or conditional sale agreement, or a
            Security Interest therein, is vested in or held by any other Person;

      provided that in the case of (ii) and (iii):-

      (1)   the terms of any such lease, conditional sale agreement or Security
            Interest will not have the effect of prejudicing the interests of
            Owner or Lessor in that Engine or Part or the interests of Trustee
            in respect thereof under the Assignments;  and

      (2)   the lessor under such lease, the seller under such conditional sale
            agreement or the holder of such Security Interest, as the case may
            be, has confirmed and acknowledged in writing to Lessor, in form and
            substance satisfactory to Lessor, that it will respect the interests
            of Owner, Lessor and Trustee in respect of that Engine or Part and
            that it will not seek to exercise any rights whatsoever in relation
            thereto.

8.15  Pooling of Engines and Parts:  Lessee will not enter into nor permit any
      pooling agreement or arrangement in respect of an Engine or Part without
      the prior written consent of Lessor.

8.16  Equipment Changes:

(a)   Lessee will not make any modification or addition to the Aircraft (each an
      "Equipment Change"), except for an Equipment Change which:-

      (i)   is expressly permitted by this Agreement, or

      (ii)  has the prior written approval of Lessor and which does not diminish
            the value, utility, condition, or airworthiness of the Aircraft;

                                      45
<PAGE>
 
(b)   So long as a Default has not occurred and is continuing, Lessee may remove
      any Equipment Change if it can be removed from the Aircraft without
      diminishing or impairing the value, utility, condition or airworthiness of
      the Aircraft; and

(c)   Lessee shall indemnify Owner, Lessor and Trustee on an After-Tax Basis for
      any and all Taxes payable by Owner, Lessor or Trustee, as the case may be,
      as a result of an Equipment Change.

8.17  Title on an Equipment Change:

(a)   Title to all Parts installed on the Aircraft whether by way of
      replacement, as the result of an Equipment Change or otherwise (except
      those installed pursuant to Clause 8.13(b)) will on installation, without
      further act, vest in Owner subject to the Head Lease and this Agreement
      free and clear of all Security Interests. Lessee will at its own expense
      take all such steps and execute, and procure the execution of, all such
      instruments as Lessor may require and which are necessary to ensure that
      title so passes to Owner according to all applicable Laws.  At any time
      when requested by Lessor, Lessee will provide evidence to Lessor's and
      Owner's satisfaction (including the provision, if required, to Lessor and
      Owner of one or more legal opinions) that title has so passed to Owner;

(b)   Lessor may require Lessee to remove any Equipment Change and to restore
      the Aircraft to its condition prior to that Equipment Change; and

(c)   Except as referred to in Clause 8.17(b) any Engine or Part at any time
      removed from the Aircraft will remain the property of Owner until a
      replacement has been made in accordance with this Agreement and until
      title in that replacement has passed, according to applicable Laws, to
      Owner subject to the Head Lease and this Agreement free of all Security
      Interests whereupon title to the replaced Engine or Part, will, provided
      no Default has occurred and is continuing, pass to Lessee.

8.18  Third Party: Lessee will procure that no person (other than Lessor, Owner,
      Trustee, Security Agent or any Bank) will act in any manner inconsistent
      with its obligations under this Agreement and that all persons will comply
      with those obligations as if references to "Lessee" included a separate
      reference to those persons.

9.    INSURANCE

9.1   Insurances: Lessee will maintain in full force during the Term, and
      thereafter as expressly required in this Agreement, insurances in respect
      of the Aircraft in form and substance satisfactory to Lessor (the
      "Insurances" which expression includes, where the context so admits, any
      relevant re-insurance(s)) through such brokers and with such insurers and
      having such deductibles and being subject to such exclusions as may be
      approved by Lessor from time to time. The Insurances will be effected
      either:-

(a)   on a direct basis with insurers of recognized standing who normally
      participate in aviation insurances in the leading international insurance
      markets and led by reputable underwriter(s) approved by Lessor; or

                                      46
<PAGE>
 
(b)   with a single insurer or group of insurers approved by Lessor who does not
      retain the risk but effects substantial reinsurance with reinsurers in the
      leading international insurance markets and through brokers each of
      recognized standing and acceptable to Lessor for a percentage acceptable
      to Lessor of all risks insured (the "Reinsurances").

9.2   Requirements: Lessor's current requirements as to required Insurances are
      as specified in this Clause and in Schedule 4. Lessor may from time to
      time stipulate other requirements for the Insurances so that the scope and
      level of cover is maintained in line with best industry practice and the
      interests of Lessor, Owner and Trustee protected.

9.3   Change: If at any time Lessor wishes to revoke its approval of any
      insurer, reinsurer, insurance or reinsurance, Lessor and/or its brokers
      will consult with Lessee and Lessee's brokers (as for the time being
      approved by Lessor) regarding whether that approval should be revoked to
      protect the interests of the parties insured. If, following the
      consultation, Lessor considers that any change should be made, Lessee will
      then arrange or procure the arrangement of alternative cover satisfactory
      to Lessor.

9.4   Insurance Covenants: Lessee will:-

(a)   ensure that all legal requirements as to insurance of the Aircraft, any
      Engine or any Part which may from time to time be imposed by the laws of
      the State of Registration or any state to, from or over which the Aircraft
      may be flown, in so far as they affect or concern the operation of the
      Aircraft, are complied with and in particular those requirements
      compliance with which is necessary to ensure that (i) the Aircraft is not
      in danger of detention or forfeiture, (ii) the Insurances remain valid and
      in full force and effect, and (iii) the interests of the Indemnitees in
      the Insurances and the Aircraft or any Part are not thereby prejudiced;

(b)   not use, cause or permit the Aircraft, any Engine or any Part to be used
      for any purpose or in any manner not covered by the Insurances or outside
      any geographical limit imposed by the Insurances;

(c)   comply with the terms and conditions of each policy of the Insurances and
      not do, consent or agree to any act or omission which:-

      (i)   invalidates or may invalidate the Insurances; or

      (ii)  renders or may render void or voidable the whole or any part of any
            of the Insurances; or

      (iii) brings any particular liability within the scope of an exclusion or
            exception to the Insurances;

(d)   not take out without the prior written approval of Lessor any insurance or
      reinsurance in respect of the Aircraft other than those required under
      this Agreement unless relating solely to hull total loss, business
      interruption, profit commission and deductible risk;

                                      47
<PAGE>
 
(e)   commence renewal procedures at least 30 days prior to expiry of any of the
      Insurances and provide to Lessor:-

      (i)   if requested by Lessor, a written status report of renewal
            negotiation 14 days prior to each expiry date;

      (ii)  telexed telecopy confirmation of completion of renewal prior to each
            expiry date; and

      (iii) certificates of insurance (and where appropriate certificates of
            reinsurance), and broker's (and any reinsurance brokers') letter of
            undertaking in a form acceptable to Lessor in English, detailing the
            coverage and confirming the insurers' (and any reinsurers')
            agreement to the specified insurance requirements of this Agreement
            within 7 days after each renewal date;

(f)   on request, provide to Lessor copies of documents or other information
      evidencing the Insurances;

(g)   on request, provide to Lessor evidence that the Insurance premiums have
      been paid;

(h)   not make any modification or alteration to the Insurances material and
      adverse to the interests of any of the Indemnitees;

(i)   be responsible for any deductible under the Insurances; and

(j)   provide any other insurance and reinsurance related information, or
      assistance, in respect of the Insurances as Lessor may reasonably require.

9.5   Failure to Insure: If Lessee fails to maintain the Insurances in
      compliance with this Agreement, each of the Indemnitees will be entitled
      but not bound, (without prejudice to any other rights of Lessor under this
      Agreement):-

(a)   to pay the premiums due or to effect and maintain insurances satisfactory
      to it or otherwise remedy Lessee's failure in such manner (including,
      without limitation to effect and maintain an "owner's interest" policy) as
      it considers appropriate. Any sums so expended by it will become
      immediately due and payable by Lessee to Lessor on an After-Tax Basis
      together with interest thereon at the rate specified in Clause 5.11, from
      the date of expenditure by it up to the date of reimbursement by Lessee;
      and

(b)   at any time while such failure is continuing to require the Aircraft to
      remain at any airport or to proceed to and remain at any airport
      designated by it until the failure is remedied to its satisfaction.

9.6   Continuing Indemnity: Lessee shall effect and maintain insurance after the
      Expiry Date with respect to its liability under the Indemnity in Clause 10
      for 2 years which provides for each Indemnitee to be named as additional
      insured.  Lessee's obligation in this Clause 

                                      48
<PAGE>
 
      shall not be affected by Lessee ceasing to be lessee of the Aircraft
      and/or any of the Indemnitees ceasing to have any interest in respect of
      the Aircraft.

9.7   Application of Insurance Proceeds:-

      As between Lessor and Lessee:-

(a)   all insurance payments received as the result of an Event of Loss or
      Engine Event of Loss occurring during the Term will be paid to Lessor and
      Lessor will pay the balance of those amounts to Lessee after deduction of
      all amounts which may be or become payable by Lessee to Lessor under this
      Agreement (including under Clause 11.1(b));

(b)   all insurance proceeds of any property, damage or loss to the Aircraft,
      any Engine or any Part occurring during the Term not constituting an Event
      of Loss or Engine Event of Loss and in excess of the Damage Notification
      Threshold will be applied in payment (or to reimburse Lessee) for repairs
      or replacement property upon Lessor being satisfied that the repairs or
      replacement have been effected in accordance with this Agreement.
      Insurance proceeds in amounts below the Damage Notification Threshold may
      be paid by the insurer directly to Lessee. Any balance remaining may be
      retained by Lessor;

(c)   all insurance proceeds in respect of third party liability will, except to
      the extent paid by the insurers to the relevant third party, be paid to
      Lessor to be paid directly in satisfaction of the relevant liability or to
      Lessee in reimbursement of any payment so made; and

(d)   notwithstanding Clauses 9.7(a), (b) or (c), if at the time of the payment
      of any such insurance proceeds a Default has occurred and is continuing,
      all such proceeds will be paid to or retained by Lessor to be applied
      toward payment of any amounts which may be or become payable by Lessee in
      such order as Lessor sees fit or as Lessor may elect.

      To the extent insurance proceeds are paid to Lessee, Lessee agrees to
      comply with the foregoing provisions and apply or pay over such proceeds
      as so required.

            PART (EITHER IN THE AIR OR ON THE GROUND) WHETHER OR NOT THE CLAIM
            MAY BE ATTRIBUTABLE TO ANY DEFECT IN THE AIRCRAFT, ANY ENGINE OR ANY
            PART OR TO ITS DESIGN, TESTING OR USE OR OTHERWISE, AND REGARDLESS
            OF WHEN THE SAME ARISES OR WHETHER IT ARISES OUT OF OR IS
            ATTRIBUTABLE TO ANY ACT OR OMISSION, NEGLIGENT OR OTHERWISE, OF ANY
            INDEMNITEE;

      (B)   WHICH ARISE OUT OF ANY ACT OR OMISSION WHICH INVALIDATES OR WHICH

      BUT EXCLUDING ANY CLAIM IN RELATION TO A PARTICULAR INDEMNITEE TO THE
      EXTENT THAT THAT CLAIM IS COVERED PURSUANT TO ANOTHER INDEMNITY PROVISION
      OF THIS AGREEMENT OR TO THE EXTENT IT ARISES SOLELY AS A RESULT OF THE
      GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THAT INDEMNITEE, LESSOR TAXES OR
      A LESSOR LIEN.

10.2  Duration: The indemnities contained in this Agreement will continue in
      full force following the end of the Term notwithstanding any breach or
      repudiation by Lessor or Lessee of this Agreement or any termination of
      the lease of the Aircraft hereunder.

11.   EVENTS OF LOSS

11.1

(a)   Pre-delivery: If an Event of Loss occurs prior to delivery of the to
      Lessee, Lessor will have the option, exercisable by giving Lessee notice
      in writing, to substitute an alternative aircraft of the same manufacture,
      model, value and utility as the Aircraft. If Lessor exercises such option,
      Lessee shall be obliged to lease such substitute aircraft pursuant to the
      terms and conditions of this Agreement and such substitute aircraft shall
      constitute the Aircraft for all purposes of this Agreement. Lessor shall
      provide Lessee with details of the substitute aircraft as soon as may be
      practicable after the occurrence of the Event of Loss. If Lessor advises
      Lessee that Lessor does not wish to exercise such option, this Agreement
      will immediately terminate and except as expressly stated in this
      Agreement neither party will have any further obligation or liability
      under this 

                                      50
<PAGE>
 
      Agreement other than pursuant to Clause 16.9 except that Lessor will
      return the Deposit to Lessee; and

(b)   Post-delivery: If an Event of Loss occurs after delivery of the Aircraft
      to Lessee, Lessee will pay the Agreed Value to Lessor on or prior to the
      earlier of (i) 5 Business Days after the Event of Loss and (ii) the date
      of receipt of insurance proceeds in respect of that Event of Loss. Subject
      to the rights of any insurers and reinsurers or other third party, upon
      irrevocable payment in full to Lessor of that amount and all other amounts
      which may be or become payable to Lessor under this Agreement, Lessor will
      without recourse or warranty (except as to Lessor's Liens) and without
      further act, be deemed to have transferred to Lessee all of Lessor's
      rights to any Engines and Parts not installed when the Event of Loss
      occurred, all on an as-is where-is basis, and will at Lessee's expense,
      execute and deliver such bills of sale and other documents and instruments
      as Lessee may reasonably request to evidence (on the public record or
      otherwise) the transfer and the vesting of Lessor's rights in such Engines
      and Parts in Lessee, free and clear of all rights of Lessor and Lessor
      Liens.

(c)   Engine Event of Loss: From the Delivery Date upon an Engine Event of Loss,
      Lessee shall give Lessor prompt written notice thereof and shall, within
      45 days after such occurrence, convey to Lessor, as replacement for the
      Engine suffering such event, title to a Replacement Engine.  Each
      Replacement Engine shall be free of all Security Interests and shall be in
      as good an operating condition as the Engine being replaced, assuming the
      Engine being replaced was in the condition and repair required by the
      terms hereof immediately prior to the Engine Event of Loss. Upon full
      compliance by Lessee with the terms of this Clause 11.1(c), Lessor will
      transfer to Lessee title to the Engine which suffered the Engine Event of
      Loss.  Prior to or at the time of any such conveyance, Lessee, at its own
      expense, will promptly (i) furnish Lessor with a full warranty bill of
      sale, in form and substance reasonably satisfactory to Lessor, with
      respect to such Replacement Engine; (ii) cause a lease supplement (in form
      and substance satisfactory to Lessor) subjecting such Replacement Engine
      to this Agreement, to be duly executed by Lessee, and recorded pursuant to
      applicable Law; (iii) furnish Lessor with such evidence of title to such
      Replacement Engine as Lessor may reasonably request; (iv) furnish Lessor
      with an opinion of Lessee's counsel to the effect that title to such
      Replacement Engine has been duly conveyed to Owner subject to the Head
      Lease and this Agreement, free and clear of all Security Interests, and
      that such Replacement Engine is duly leased hereunder; (v) furnish a
      certificate signed by a duly authorized financial officer or executive of
      Lessee certifying that, upon consummation of such replacement, no Event of
      Default will have occurred or be continuing; (vi) furnish Lessor with such
      documents as Lessor may reasonably request in connection with the
      consummation of the transactions contemplated by this Clause 11.1(c), in
      each case in form and substance satisfactory to Lessor; and (vii) furnish
      such Financing Statements incorporating the Replacement Engine as may be
      requested by Lessor.  For all purposes hereof, each such Replacement
      Engine shall be deemed part of the property leased hereunder, shall be
      deemed an "Engine" as defined herein and shall be deemed part of the same
      Aircraft as was the Engine replaced thereof.  No Engine Event of Loss
      covered by this Clause 

                                      51
<PAGE>
 
      11.1(c) shall result in any reduction in Rent or affect Lessee's
      obligation to pay Engine Maintenance Reserves or the amount thereof to be
      paid by Lessee.

      Lessee shall indemnify each Indemnitee on an After-Tax Basis for any
      adverse tax consequence to such Indemnitee of the replacement of one or
      more Engines pursuant to this Clause 11.1.

11.2  Substitute Aircraft:

(a)   Without prejudice to the provisions of Clause 11.1 (b), if an Event of
      Loss occurs after delivery of the Aircraft to Lessee, Lessor will have the
      option, exercisable by giving Lessee notice in writing, to substitute an
      alternative aircraft (the "Substitute Aircraft") of the same manufacture
      and model as the Aircraft and having a value, utility and condition equal
      to or greater than the Aircraft as at the date of occurrence of the Event
      of Loss which Substitute Aircraft will be leased by Lessor to Lessee for
      the remainder of the Term pursuant to the terms and conditions of this
      Agreement.  If Lessor exercises such option, the Substitute Aircraft will
      constitute the Aircraft for all purposes of this Agreement in respect of
      facts and circumstances arising after the date of delivery thereof to
      Lessee.  Lessor shall provide Lessee with details of the Substitute
      Aircraft as soon as may be practicable after the occurrence of the Event
      of Loss;

(b)   Lessor will use all reasonable endeavors to deliver the Substitute
      Aircraft to Lessee as soon as may be practicable following the date of
      occurrence of the Event of Loss but not later than 3 months after such
      date; and

(c)   Lessee agrees to enter into such documentation as Lessor may require in
      order to reflect the leasing of the Substitute Aircraft as aforesaid
      including, without limitation, documentation in respect of the Insurances.

      Lessee shall indemnify each Indemnitee on an After-Tax Basis for any
      adverse tax consequence to such Indemnitee of the replacement of the
      Aircraft or Airframe pursuant to this Clause 11.2.

11.3  Requisition: During any requisition for use or hire of the Aircraft, any
      Engine or Part which does not constitute an Event of Loss:-

(a)   the Rent and other charges payable under this Agreement will not be
      suspended or abated either in whole or in part, and Lessee will not be
      released from any of its other obligations under the Agreement (other than
      operational obligations with which Lessee is unable to comply solely by
      virtue of the requisition); and

(b)   so long as no Default has occurred and is continuing, Lessee will be
      entitled to any hire paid by the requisitioning authority in respect of
      the Term. Lessee will, as soon as practicable after the end of any such
      requisition, cause the Aircraft to be put into the condition required by
      this Agreement. Lessor will be entitled to all compensation payable by the
      requisitioning authority in respect of any change in the structure, state
      or condition of the Aircraft arising during the period of requisition, and
      Lessor will apply 

                                      52
<PAGE>
 
      such compensation in reimbursing Lessee for the cost of complying with its
      obligations under this Agreement in respect of any such change, but so
      that, if any Default has occurred and is continuing, Lessor may apply the
      compensation or hire in or towards settlement of any amounts owing by
      Lessee under this Agreement.

12.   RETURN OF AIRCRAFT

12.1  Return: On the Expiry Date or redelivery of the Aircraft pursuant to
      Clause 13.2 or termination of the leasing of the Aircraft under this
      Agreement Lessee will, unless an Event of Loss has occurred, at its
      expense, redeliver the Aircraft and Aircraft Documents to Lessor at the
      Redelivery Location or such other airport as is mutually acceptable to the
      parties hereto, in accordance with the procedures and in compliance with
      the conditions set forth in Schedule 3, free and clear of all Security
      Interests and Permitted Liens (other than Lessor Liens) and in a condition
      qualifying for immediate certification of airworthiness by the FAA or as
      otherwise agreed by Lessor and Lessee, and, if requested by Lessor,
      thereupon cause the Aircraft to be deregistered by the Air Authority.

12.2  Final Inspection: Immediately prior to redelivery of the Aircraft, Lessee
      will make the Aircraft available to Lessor for inspection ("Final
      Inspection") in order to verify that the condition of the Aircraft
      complies with this Agreement. The Final Inspection will be long enough to
      permit Lessor to:-

(a)   inspect the Aircraft Documents;

(b)   inspect the Aircraft and uninstalled Parts;

(c)   inspect the Engines, including without limitation (i) a borescope
      inspection of (A) the low pressure and high pressure compressors and (B)
      turbine and combustion areas, (ii) engine condition runs and (iii) review
      of Engine trend monitoring data and technical log reports covering the
      last ninety (90) days of operation; and

(d)   perform a complete borescope inspection of the APU; and

(e)   observe a 2 hour demonstration flight (with Lessor's representatives as
      on-board observers).

12.3  Non-Compliance: To the extent that, at the time of Final Inspection, the
      condition of the Aircraft does not comply with this Agreement, Lessee will
      at Lessor's option:-

(a)   immediately rectify the non-compliance and to the extent the non-
      compliance extends beyond the Expiry Date, the Term will be automatically
      extended and this Agreement will remain in force until the non-compliance
      has been rectified with Lessee being obligated to pay Rent with respect to
      the period of such extension on a per diem basis; or

                                      53
<PAGE>
 
(b)   redeliver the Aircraft to Lessor and indemnify Lessor on an After-Tax
      Basis, and provide to Lessor's satisfaction cash as security for that
      indemnity, against the cost of putting the Aircraft into the condition
      required by this Agreement.

12.4  Redelivery: Upon redelivery Lessee will provide to Lessor, upon Lessor's
      request, all documents necessary to export the Aircraft from the Habitual
      Base (including, without limitation, a valid and subsisting export license
      for the Aircraft) and required in relation to the deregistration of the
      Aircraft with the Air Authority.

12.5  Acknowledgment: Provided Lessee has complied with its obligations under
      this Agreement, following redelivery of the Aircraft by Lessee to Lessor
      at the Redelivery Location, Lessor will deliver to Lessee an
      acknowledgment confirming that Lessee has redelivered the Aircraft to
      Lessor in accordance with this Agreement.

12.6  Maintenance Program:

(a)   Prior to the Expiry Date and upon Lessor's request, Lessee will provide
      Lessor or its agent reasonable access to the Agreed Maintenance Program
      and the Aircraft Documents in order to facilitate the Aircraft's
      integration into any subsequent operator's fleet; and

(b)   Lessee will, if requested by Lessor to do so, upon return of the Aircraft
      deliver to Lessor a certified true current and complete copy of the Agreed
      Maintenance Program. Lessor agrees that it will not disclose the contents
      of the Agreed Maintenance Program to any person or entity except to the
      extent necessary to monitor Lessee's compliance with this Agreement and/or
      to bridge the maintenance program for the Aircraft from the Agreed
      Maintenance Program to another program after the Expiry Date.

12.7  Fuel: Upon redelivery of the Aircraft to Lessor, an adjustment will be
      made in respect of fuel on board on the Delivery Date and the Expiry Date
      at the price then prevailing at the Redelivery Location.

13.   DEFAULT

13.1  Events:  Each of the following events will constitute an Event of Default

      decree or order of any court or any order, rule or regulation of any
      Government Entity).  Lessee acknowledges that the occurrence of any Event

(c)   Breach: Lessee fails to comply with any other provision of this Agreement
      and, if such failure is in the reasonable opinion of Lessor capable of
      remedy, the failure continues for 5 days after notice from Lessor to
      Lessee; or

(d)   Representation: any representation or warranty made (or deemed to be
      repeated) by Lessee in or pursuant to this Agreement or in any document or
      certificate or statement is or proves to have been incorrect in any
      material respect when made or deemed to be repeated; or

(e)   Cross Default:

      (i)   a final judgment for the payment of money not covered by insurance
            in excess of Two Hundred Fifty Thousand Dollars ($250,000), or final

            remain undischarged for a period of ninety (90) days during which
            execution thereof shall not be effectively stayed by agreement of
            the parties involved, stayed by court order or adequately bonded; or

      (ii)  attachments or other Security Interests shall be issued or entered
            against substantially all of the property of Lessee and shall remain

            Interests created in connection with monies borrowed or obligations
            agreed to by Lessee in the ordinary course of its business; or

      (iii) Lessee shall default in the payment of any sum which by itself is
            in excess of $100,000 or any sums which in aggregate exceed $250,000
            notwithstanding that any particular individual sum thereof does not
            exceed $100,000 in respect of any one or more obligations for the
            payment of borrowed money, for the deferred purchase price of
            property or for the payment of rent or hire under any lease of
            aircraft when the same becomes due if such nonpayment results in or
            would permit an acceleration of such indebtedness, or Lessee shall
            default in the performance of any other term, agreement, or
            condition contained in any agreement or instrument under or by which
            any such obligation is created, evidenced or secured, if the effect
            of such default is to cause or permit such obligation to become due
            prior to its stated maturity; or

      (iv)  any event of default or termination event, howsoever described,
            occurs under the Other Agreements; or

<PAGE>
 
            compensate Lessor for any loss of or damage to Lessors residual

            property, or otherwise, caused by such entry or taking, except
            damages caused by gross negligence or willful misconduct; and Lessor
            is hereby irrevocably, by way of security for Lessee's obligations
            under this Agreement, appointed attorney for Lessee in causing the
            redelivery or in directing the pilots of Lessee or other pilots to
            fly the Aircraft to that airport and will have all the powers and
            authorizations necessary for taking that action; or

      (ii)  by serving notice require Lessee to redeliver the Aircraft to Lessor
            at Shannon International Airport, Ireland (or such other location as
            Lessor may require); and/or

      operate or lease to others the Aircraft as Lessor in its sole discretion
      may determine, all free and clear of any rights of Lessee; and/or

(f)   whether or not Lessor shall have exercised, or shall thereafter at any
      time exercise, any of its rights under paragraph (a), paragraph (b),
      paragraph (c), paragraph (d), or paragraph (e) of this Clause 13.2,
      Lessor, by 30 days written notice to Lessee specifying a payment date, may
      demand that Lessee pay to Lessor, and Lessee shall pay to Lessor, on the
      payment date specified in such notice, as liquidated damages for loss of
      bargain and not as a penalty (in lieu of the Rent due for the period
      commencing after the date specified for payment in such notice), any
      unpaid Rent for the Aircraft and other amounts owing under this Agreement
      (prorated in the case of Rent on a daily basis) to and including the
      payment date specified in such notice, plus the amount, if any, by which
      the aggregate Rent for the remainder of the Term (determined without
      reference to any right of Lessor to terminate the leasing of the Aircraft,
      whether or not such right is exercised), discounted periodically (equal to
      installment frequency) to present worth at the interest rate of 4 percent
      (4%) per annum, exceeds the fair market rental value (determined pursuant
      to the Appraisal Procedure) of the Aircraft for the remainder of the Term,
      after discounting such fair market rental value periodically (equal to
      installment frequency) to present worth as of the payment date specified
      in such notice at the interest rate of 4 percent (4%) per annum; and/or

                                      59
<PAGE>
 
(g)   In the event that Lessor, pursuant to Clause 13.2(e) above, shall have
      relet the Aircraft under a lease which extends at least to the date upon
      which the Term for the Aircraft would have expired but for Lessee's
      default, Lessor, in lieu of exercising its rights under Clause 13.2(f)
      above with respect to the Aircraft, may, if it shall so elect, demand that
      Lessee pay Lessor, and Lessee shall pay Lessor, as liquidated damages for
      loss of bargain and not as a penalty (in lieu of the Rent for the Aircraft
      due after the time of reletting) any unpaid Rent for the Aircraft due up
      to the date of reletting and any other amounts owing under this Agreement,
      plus the amount, if any, by which the aggregate Rent for the Aircraft,
      which would otherwise have become due over the remainder of the Term
      (determined without reference to any right of Lessor to terminate the
      leasing of the Aircraft, whether or not such right is exercised),
      discounted periodically (equal to installment frequency) to present worth
      as of the date of reletting at the interest rate of 4 percent (4%) per
      annum, exceeds the aggregate basic rental payments to become due under the
      reletting from the date of such reletting to the date upon which the Term
      for the Aircraft would have expired but for Lessee's default, discounted
      periodically (equal to installment frequency) to present worth as of the
      date of the reletting at the interest rate of 4 percent (4%) per annum;
      and/or

(h)   in lieu of the remedies set forth in paragraphs (a), (c), (d), (e), (f),
      and (g) of this Clause 13.2, by 30 days written notice to Lessee
      specifying a payment date, Lessor may demand that Lessee pay to Lessor,
      and Lessee shall pay to Lessor on the payment date specified in such
      notice as liquidated damages for loss of bargain and not as a penalty (in
      lieu of the Rent due for the period commencing after the date specified
      for payment in such notice), any unpaid Rent for the Aircraft and other
      amounts payable under this Agreement (prorated in the case of Rent on a
      daily basis) to and including the payment date specified in such notice,
      plus an amount equaling the aggregate Rent for the remainder of the Term,
      discounted periodically (equal to installment frequency) to present worth
      at the interest rate of 4 per cent (4%) per annum;

(i)   draw upon the Deposit or the Maintenance Reserves and apply such amounts
      to amounts owing to Lessor hereunder.

      Lessee, for itself and for its successors and assigns, hereby agrees that,
      to the extent now or hereafter permitted by applicable Law,
      notwithstanding any provision of the Federal Bankruptcy Code as amended
      from time to time, the title of Lessor to the Aircraft and any right of
      Lessor to take possession of the Aircraft in compliance with the
      provisions of this Agreement, in each case, upon the occurrence and
      continuance of an Event of Default, shall not be affected by the
      provisions of the Federal Bankruptcy Code, as amended from time to time.

      In addition to the foregoing, Lessee shall be liable for any and all
      unpaid Rent and other amounts payable under this Agreement during or after
      the exercise of any of the aforementioned remedies, together with interest
      on such unpaid amounts at the rate set forth in Clause 5.11, and until
      satisfaction of all of Lessee's obligations to Lessor hereunder and (on an
      After-Tax Basis) for all reasonable legal fees and other reasonable costs
      and expenses incurred by Lessor by reason of the occurrence of any Event
      of 

                                      60
<PAGE>
 
      Default or the exercise of Lessor's remedies with respect thereto,
      including all costs and expenses incurred in connection with the return of
      the Aircraft in accordance with the terms of Clause 12 hereof or in
      placing the Aircraft in the condition and with airworthiness certification
      as required by such Clause.

      In effecting any repossession, Lessor and its representatives and agents,
      to the extent permitted by Law, shall: (i) have the right to enter upon
      any premises where it reasonably believes the Aircraft, the Airframe, an
      Engine or Part to be located; (ii) not be liable, in conversion or
      otherwise, for the taking of any personal property of Lessee which is in
      or attached to the Aircraft, the Airframe, an Engine or Part which is
      repossessed; provided, however, that Lessor shall return to Lessee all
      personal property of Lessee or its passengers which was on the Aircraft at
      the time Lessor re-takes possession of the Aircraft; (iii) not be liable
      or responsible, in any manner, for any inadvertent damage or injury to any
      of Lessee's property in repossessing and holding the Aircraft, the
      Airframe, an Engine or Part, except for that caused by or in connection
      with Lessor's gross negligence or willful acts; (iv) have the right to
      maintain possession of and dispose of the Aircraft, the Airframe, an
      Engine or Part on any premises owned by Lessee or under Lessee's control;
      and (v) have the right to obtain a key to any premises at which the
      Aircraft, the Airframe, an Engine or Part may be located from the landlord
      or owner thereof.

      If reasonably required by Lessor, Lessee, at its sole expense, shall
      assemble and make the Aircraft, the Airframe, an Engine or Part available
      at a place designated by Lessor in accordance with Clause 12 hereof.
      Lessee hereby agrees that, in the event of the return to or repossession
      by Lessor of the Aircraft, the Airframe, an Engine or Part, any rights in
      any warranty (express or implied) previously assigned to Lessee or
      otherwise held by Lessee shall without further act, notice or writing be
      assigned or reassigned to Lessor, if assignable.  Lessee shall be liable
      to Lessor on an After-Tax Basis for all reasonable expenses,
      disbursements, costs and fees incurred in (i) repossessing, storing,
      preserving, shipping, maintaining, repairing and refurbishing the
      Aircraft, the Airframe, an Engine or Part to the condition required by
      Clause 12 hereof and (ii) preparing the Aircraft, the Airframe, an Engine
      or Part for sale or lease, advertising the sale or lease of the Aircraft,
      the Airframe, an  Engine or Part and selling or releasing the Aircraft,
      the Airframe, an Engine or Part.  Lessor is hereby authorized and
      instructed, at its option, to make reasonable expenditures which Lessor
      considers advisable to repair and restore the Aircraft, the Airframe, an
      Engine or Part to the condition required by Clause 12 hereof, all at
      Lessee's sole expense.

      At any public sale of the Aircraft, the Airframe, an Engine or Part
      pursuant to this Clause, Lessor may bid for and purchase such property and
      Lessee agrees that the amounts paid therefor shall be used in the
      computation contemplated herein.

      With the exception that the remedy in Clause 13.2(g) can be elected only
      if the remedy in Clause 13.2(f) is not elected and the remedy in Clause
      13.2(h) can be elected only in lieu of all other remedies save the
      remedies in Clauses 13.2(b) and 13.2(i), no remedy referred to in this
      Clause 13 is intended to be exclusive, but, to the extent permissible

                                      61
<PAGE>
 
      hereunder or under applicable Law, each shall be cumulative and in
      addition to any other remedy referred to above or otherwise available to
      Lessor at Law or in equity; and the exercise or beginning of exercise by
      Lessor of any one or more of such remedies shall not preclude the
      simultaneous or later exercise by Lessor of any or all of such other
      remedies; provided, however, that nothing in this Clause 13 shall be
      construed to permit Lessor to obtain a duplicate recovery of any element
      of damages to which Lessor is entitled.  No express or implied waiver by
      Lessor of any Default or Event of Default shall in any way be, or be
      construed to be, a waiver of any future or subsequent Default.

13.3  Deregistration: If an Event of Default occurs, Lessor may sell or
      otherwise deal with the Aircraft free and clear of any leasehold or other
      interest of Lessee as if this Agreement had never been made and Lessee
      will at the request of Lessor take all steps necessary to effect (if
      applicable) deregistration of the Aircraft and its export from the country
      where the Aircraft is for the time being situated and any other steps
      necessary to enable the Aircraft to be redelivered to Lessor in accordance
      with this Agreement including without limitation execution and filing of a
      certificate or other instrument of lease termination with the Air
      Authority and; Lessee hereby irrevocably and by way of security for its
      obligations under this Agreement appoints (which appointment is coupled
      with an interest) Lessor as its attorney to execute and deliver any
      documentation and to do any act or thing required in connection with the
      foregoing.

14.   ASSIGNMENT

14.1  Lessee's Assignment: LESSEE WILL NOT ASSIGN, TRANSFER (VOLUNTARILY OR
      INVOLUNTARILY BY OPERATION OF LAW OR OTHERWISE) OR CREATE OR PERMIT TO
      EXIST ANY SECURITY INTEREST OVER, ANY OF ITS RIGHTS UNDER THIS AGREEMENT.

14.2  Lessor's Assignment: Lessor may assign or transfer all or any of its
      rights under this Agreement and in the Aircraft.  In the case of an
      assignment other than by way of security, Lessor will be released from and
      will have no further obligation under this Agreement following the
      assignment of all its rights under this Agreement and the assumption by
      the assignee or transferee of all of Lessor's obligations under this
      Agreement.  Notwithstanding any such assignment, Lessor will remain
      entitled to the benefit of each indemnity and the liability insurances
      effected under this Agreement. Lessee will comply with all reasonable
      requests of Lessor, its successors and assigns in respect of any such
      assignment. Lessor will promptly notify Lessee of any assignment.

14.3  Transfer: If Lessor desires to effect any assignment or transfer of its
      rights and obligations under this Agreement, Lessee agrees to cooperate
      and take all such steps as Lessor may reasonably request to give the
      transferee the benefit of this Agreement and to acknowledge the release of
      Lessor from its obligations hereunder as of the time of such assignment or
      transfer.

15.   ILLEGALITY

      If it is or becomes unlawful in any jurisdiction for Lessor to give effect
      to any of its obligations as contemplated by this Agreement or to continue
      this Agreement, Lessor may by notice in writing to Lessee terminate the
      leasing of the Aircraft under this Agreement and Lessee will forthwith
      redeliver the Aircraft to Lessor in accordance with Clause 12. Without
      prejudice to the foregoing Lessor will consult in good faith with Lessee
      as to any steps which may be taken to restructure the transaction to avoid
      that unlawfulness but will be under no obligation to take any such steps.

15A   Lease Amendment

15A.1 As of, and with effect from, the Adjustment Date, this Agreement shall be
      amended by the incorporation herein of the amendments set out in Schedule
      8 to this Agreement.

15A.2 Lessee will arrange to have original certificates of insurance and, if
      applicable, reinsurance and an undertaking or undertakings from the
      Lessee's insurance brokers in accordance with the provisions of this
      Agreement (as amended from the Adjustment Date in accordance with this
      Clause 15A) made available to Lessor on or before the Adjustment Date,
      provided that if original certificates and undertakings are not available
      on or before the Adjustment Date, Lessor will accept copies thereof.

15A.3 Without prejudice to the generality of Clause 8.10(b) of this Agreement,
      Lessee agrees to co-operate with Lessor in order to make any filing or
      registration or to modify any existing filing or registration with the Air
      Authority in order to reflect the release, on or after the Adjustment
      Date, of any security created or to be created by the Lessor and/or Owner.

15A.4 Except as expressly set forth in Schedule 8 the notification by the Lessor
      to the Lessee of the Adjustment Date shall not affect the rights and
      obligations of the Lessee under this Agreement.

16.   MISCELLANEOUS

16.1  Waivers, Remedies Cumulative: The rights of Lessor under this Agreement:-

      (i)   may be exercised as often as necessary;

      (ii)  are cumulative and not exclusive of its rights under any Law; and

      (iii)  may be waived only in writing and specifically.

      Delay in exercising or non-exercise of any such right will not constitute
      a waiver of that right.

16.2  Delegation: Lessor may delegate to any person or persons all or any of the
      trusts, powers or discretions vested in it by these presents and any such
      delegation may be made 

                                      63
<PAGE>
 
      upon such terms and conditions and subject to such regulations (including
      power to sub-delegate) as Lessor in its absolute discretion thinks fit.

16.3  Certificates: Save where expressly provided in this Agreement, any
      certificate or determination by Lessor as to any rate of interest or as to
      any other amount payable under this Agreement will, in the absence of
      manifest error, be conclusive and binding on Lessee.

16.4  Appropriation: If any sum paid or recovered in respect of the liabilities
      of Lessee under this Agreement is less than the amount then due, Lessor
      may apply that sum to amounts due under this Agreement in such proportions
      and order and generally in such manner as Lessor may determine at its sole
      discretion.

16.5  Currency:

      Lessee acknowledges that the specification of Dollars in this Agreement is
      of the essence and that Dollars shall be the currency of account in any
      and all events.  Lessee waives any right it may have in any jurisdiction
      to pay any amount under this Agreement in a currency other than Dollars.

16.6  Set-off: Lessor may set off any matured obligation owed by Lessee under
      this Agreement, the Other Agreements to which Lessor is a party or under
      any other agreement between Lessor (or any affiliate or associate of
      Lessor) and Lessee (to the extent beneficially owned by Lessor) against
      any obligation (whether or not matured) owed by Lessor to Lessee,
      regardless of the place of payment or currency. If the obligations are in
      different currencies, Lessor may convert either obligation at the market
      rate of exchange available in New York or at its option London for the
      purpose of the set-off. If an obligation is unascertained or unliquidated,
      Lessor may in good faith estimate that obligation and set off in respect
      of the estimate, subject to the relevant party accounting to the other
      when the obligation is ascertained or liquidated. Lessor will not be
      obliged to pay any amounts to Lessee under this Agreement so long as any
      sums which are then due from Lessee under this Agreement, the Other
      Agreements or under any other agreement between Lessor (or any affiliate
      or associate of Lessor) and Lessee remain unpaid and any such amounts
      which would otherwise be due will fall due only if and when Lessee has
      paid all such sums except to the extent Lessor otherwise agrees or sets
      off such amounts against such payment pursuant to the foregoing.

16.7  Severability: If a provision of this Agreement is or becomes illegal,
      invalid or unenforceable in any jurisdiction, that will not affect:-

(a)   the legality, validity or enforceability in that jurisdiction of any other
      provision of this Agreement; or

(b)   the legality, validity or enforceability in any other jurisdiction of that
      or any other provision of this Agreement.

                                      64
<PAGE>
 
16.8  Remedy: If Lessee fails to comply with any provision of this Agreement,
      Lessor may, without being in any way obliged to do so or responsible for
      so doing and without prejudice to the ability of Lessor to treat the non-
      compliance as a Default or an Event of Default, effect compliance on
      behalf of Lessee, whereupon Lessee shall become liable to pay immediately
      any sums expended by Lessor together with all costs and expenses
      (including legal costs) in connection therewith.

16.9  Expenses: Whether or not the Aircraft is delivered to Lessee pursuant to
      this Agreement, Lessee will pay to Lessor on an After-Tax Basis on
      demand:-

      (a)   all costs associated with perfecting the Owner's, the Trustee's, the
            Banks and/or the Lessor's rights in the Aircraft and/or this
            Agreement in the State of Registration, the Habitual Base of the
            Aircraft (and other states as appropriate given the operation of the
            Aircraft), including (but not limited to) the provision of legal
            opinions, tax advice, stamp duties, translations and registrations,
            whether required by Lessor or Lessee.

      (b)   all expenses (including legal, professional, and out-of-pocket
            expenses) incurred or payable by Lessor related to any amendment to
            or extension of or other documentation in connection with, or the
            granting of any waiver or consent under this Agreement requested by
            Lessee or the monitoring of compliance by Lessee with this
            Agreement; and

      (c)   all expenses (including legal, survey and other costs) payable or
            incurred by Lessor in contemplation of, or otherwise in connection
            with, the enforcement of or preservation of any of Lessor's or
            Owner's rights under this Agreement, or in respect of the
            repossession of the Aircraft.

      All expenses payable pursuant to this Clause 16.9 will be paid in the
      currency in which they are incurred by Lessor.

16.10 Time of Essence: The time stipulated in this Agreement for all payments
      payable by Lessee to Lessor and the prompt, punctual and performance of
      Lessee's other obligations under this Agreement are of the essence of this
      Agreement.

16.11 Notices: All notices under, or in connection with, this Agreement will,
      unless otherwise stated, be given in writing by letter, facsimile or
      SITA.  Any such notice is deemed effectively to be given as follows:-

      (i)   if by letter, on the earlier of the date when delivered or the 7th
            day after dispatch;

      (ii)  if by facsimile or SITA, when transmitted and full transmission has
            been separately notified by telephone by the transmitting party.

      The address, telex numbers, SITA, facsimile and telephone numbers of
      Lessee, Lessor and Owner are as follows:-

      this Agreement (other than Lessor) are given to Lessor on behalf of that
      Indemnitee.

16.15 Counterparts: This Agreement may be executed in two or more counterparts,
      each of which shall be deemed an original, but all of which together shall
      constitute one and the same instrument. To the extent, if any, that this
      Agreement constitutes chattel paper (as such term is defined in the
      Uniform Commercial Code as in effect in any applicable jurisdiction) no
      Security Interest in this Agreement may be created through the transfer or
      possession of any counterpart other than the counterpart that has been
      marked "Counterpart No. 1" on the cover page thereof.

16.16 Language: All notices to be given under this Agreement will be in
      English.  All documents delivered to Lessor pursuant to this Agreement
      will be in English, or if not in English, will be accompanied by a
      certified English translation.  If there is any inconsistency between the
      English version of this Agreement and any version in any other language,
      the English version will prevail.

16.17 No Brokers: Lessee hereby represents and warrants that it has not paid,
      agreed to pay or caused to be paid directly or indirectly in any form, any
      commission, percentage, contingent fee, brokerage or other similar
      payments of any kind, in connection with the establishment or operation of
      this Agreement, to any employee of Lessor or to any person or entity in
      the State of Registration or elsewhere, except to Excluded Persons, as
      herein defined.  Lessor hereby represents and warrants that it has not
      paid, agreed to pay or caused to be paid directly or indirectly in any
      form, any commission, percentage, contingent fee, brokerage or other
      similar payments of any kind, in connection with the establishment or
      operation of this Agreement, to any employee of Lessee or to any person or
      entity in the State of Registration or elsewhere, except to Excluded
      Persons, as herein defined.  For the purposes hereof, the term "Excluded
      Persons" shall mean (x) in the case of Lessor, any of its officers,
      directors, employees, attorneys or other professional advisors, whether
      located in the State of Registration or elsewhere, and (y) in the case of
      Lessee, any of its officers, directors, employees, attorneys or other
      professional advisors, whether located in the State of Registration or
      elsewhere.  Each party agrees to indemnify and hold the other harmless
      from and against any and all claims, suits, damages, costs and expenses
      (including, but not limited to reasonable attorneys' fees) asserted by any
      agent, broker or other third party for any commission or compensation of
      any nature whatsoever based upon this Agreement or the Operative Documents
      or the Aircraft, if such claim damage, cost or expense arises out of any
      action or alleged action by the indemnifying party, its employees or
      agents.

18.   SECTION 1110

      Lessee acknowledges that Lessor would not have entered into this Agreement
      unless it had available to it the benefits of a lessor under Section 1110
      of Title 11 of the United States Code.  Lessee covenants and agrees with
      Lessor that to better ensure the availability of such benefits, Lessee
      shall support any motion, petition or application filed by Lessor with any
      bankruptcy court having jurisdiction over Lessee, whereby Lessor seeks
      recovery of possession of the Aircraft under said Section 1110 and shall
      not in any way oppose such action by Lessor unless Lessee shall have
      complied with the requirements of said Section 1110 to be fulfilled in
      order to entitle Lessee to continued use and possession of the Aircraft
      hereunder.  In the event said Section 1110 is amended, or if it is
      repealed and another statute is enacted in lieu thereof, Lessor and Lessee
      agree to amend this Agreement and take such other action not inconsistent
      with this Agreement as Lessor reasonably deems necessary so as to afford
      to Lessor the rights and benefits as such amended or substituted statute
      confers upon owners and lessors of aircraft similarly situated to Lessor.

19.   USURY LAWS:  The parties intend to contract in strict compliance with the
      usury Laws of the States of California and Colorado and, to the extent
      applicable, the United States of America.  Notwithstanding anything to the
      contrary in the Operative Documents, Lessee will not be obligated to pay
      any interest in excess of the maximum non-usurious interest rate, as in
      effect from time to time, which may by applicable Law be charged,
      contracted for, reserved, received or collected by Lessor in connection
      with 

                                      71
<PAGE>
 
      the Operative Documents. During any period of time in which the then-
      applicable highest lawful rate is lower than the rate specified in Clauses
      5.11 or 13.2, interest will accrue and be payable at such highest lawful
      rate; however, if at later times such highest lawful rate is greater than
      the rate specified in Clauses 5.11 or 13.2, then Lessee will pay interest
      at the highest lawful rate until the aggregate amount of interest paid by
      Lessee equals the amount of interest that would have been payable in
      accordance with the interest rate specified in Clauses 5.11 or 13.2.

20.   MODIFICATION OR REVISION:

      Neither this Agreement nor any term of this Agreement may be modified,
      rescinded, changed waived, discharged or terminated except by a writing
      signed by the party to be charged.  Lessor and Lessee acknowledge their
      agreement to the provision of this Clause 20 by their initials below:-

                            INSURANCE REQUIREMENTS

      The Insurances required to be maintained are as follows:-

(a)   HULL ALL RISKS of Loss or Damage whilst flying and on the ground with
      respect to the Aircraft on an "agreed value basis" for the Agreed Value
      and with a deductible not exceeding $250,000, or such other amount agreed
      by Lessor from time to time;

(b)   [HULL WAR AND ALLIED PERILS, being such risks excluded from the Hull All
      Risks Policy to the fullest extent available from the leading
      international insurance markets including confiscation and requisition by
      the State of Registration for the Agreed Value, however, when the Aircraft
      is being operated solely in or over the United States of America and/or
      Canada, coverage may be limited to such perils as are customarily insured
      by comparable airlines, operating similar equipment in similar
      circumstances;]

(c)   ALL RISKS (INCLUDING WAR AND ALLIED RISK except when on the ground or in
      transit other than by air) property insurance on all Engines and Parts
      when not installed on the Aircraft on an "agreed value" basis for their
      full replacement value and including engine test and running risks;

(d)   AIRCRAFT THIRD PARTY, PROPERTY DAMAGE, PASSENGER, BAGGAGE, CARGO AND MAIL
      AND AIRLINE GENERAL THIRD PARTY (INCLUDING PRODUCTS) LEGAL LIABILITY for a
      Combined Single Limit (Bodily Injury/Property Damage) of an amount not
      less than the Minimum Liability Coverage for the time being any one
      occurrence (but in respect of products and personal injury liability this
      limit may be an aggregate limit for any and all losses occurring during
      the currency of the policy). [War and Allied Risks are also to be covered
      under the Policy in line with prudent market practice for comparable
      airlines, operating similar equipment in similar circumstances (AVN52C is
      the current market language)];

(e)   All required hull and spares insurance (as specified above), so far as it
      relates to the Aircraft will: -

      (i)    name Lessor, Owner, Trustee and their respective successors and
             assigns as additional assureds for their respective rights and

             interest;

             Lessee, subject to final prior approval of Security Agent and will
             be payable in Dollars to Security Agent, for the account of all
             interests except where the loss does not exceed the Damage
             Notification Threshold, and neither Lessor nor Security Agent has
             notified the insurers to the contrary, in which case the loss will
             be settled with and paid to Lessee;

                                      85
<PAGE>

      (iv)   if separate Hull "all risks" and "war risks" insurances are
             arranged, include a 50/50 provision in accordance with market
             practice (AVS. 103 is the current market language);

      (v)    confirm that the insurers are not entitled to replace the Aircraft
             in the event of an insured Event of Loss;

      (vi)   confirm that the insurers will not obtain a valid discharge of the

             and indemnitees as additional insureds for their respective rights
             and interests, warranted, each as to itself only, no operational
             interest;

      (ii)   include a Severability of Interest Clause which provides that the
             insurance, except for the limit of liability, will operate to give
             each assured the same protection as if there was a separate policy
             issued to each assured;

      (iii)  contain a provision confirming that the policy is primary without
             right of contribution and the liability of the insurers will not be

             Lessee have the benefit so as to reduce the amount payable to the
             additional insureds under such policies;

(g)  All Insurances will:-

     (i)     be in accordance with normal industry practice of persons operating
             similar aircraft in similar circumstances;

             Lessor may reasonably require in relation to liability insurance;

     (iii)   operate on a worldwide basis subject to such limitations and
             exclusions as Lessor may agree;

             assignment in favor of Owner;

                                      86
<PAGE>
 
     (v)     provide that, in relation to the interests of each of the
             additional assureds the Insurances will not be invalidated by any
             act or omission by Lessee, or any other person other than the
             respective additional assured seeking protection and shall insure
             the interests of each of the additional assureds regardless of any
             breach or violation by Lessee, or any other person other than the
             respective additional assured seeking protection of any warranty,
             declaration or condition, contained in such Insurances;

     (vi)    provide that the insurers will hold harmless and waive any rights
             of recourse and/or subrogation against the additional assureds,
             including GECASI and GECASL or to be subrogated to any rights of
             Trustee against Lessor, Owner, GECASI, GECASL or Lessee;

     (vii)   provide that the additional assureds will have no obligation or
             responsibility for the payment of any premiums due (but reserve the
             right to pay the same should any of them elect so to do) and that
             the insurers will not exercise any right of set-off or counter-
             claim in respect of any premium due against the respective
             interests of the additional assureds other than outstanding
             premiums relating to the Aircraft, any Engine or Part the subject
             of the relevant claim;

     (viii)  provide that the Insurances will continue unaltered for the benefit
             of the additional assureds for at least 30 days after written
             notice by registered mail or telex of any cancellation, change,
             event of non-payment of premium or installment thereof has been
             sent to Lessor, Owner and Security Agent, except in the case of war
             risks for which 7 days (or such lesser period as is or may be
             customarily available in respect of war risks or allied perils)
             will be given, or in the case of war between the 5 great powers or
             nuclear peril for which termination is automatic;

     (ix)    if reinsurance is a requirement of this Agreement such reinsurance
             will (i) be on the same terms as the original insurances and will
             include the provisions of this Schedule, (ii) provide that

             would have fallen due under the relevant policy of reinsurance if
             the reinsured had (immediately before such bankruptcy, insolvency,
             liquidation, dissolution or similar proceedings) discharged its
             obligations in full under the original insurance policies in
             respect of which the then relevant policy of reinsurance has been
             effected; and (iii) contain a "cut-through" clause in the following
             form (or otherwise, satisfactory to Lessor): "The Reinsurers and
             the Reinsured hereby mutually agree that in the event of any claim
             arising under the reinsurances in respect of a total loss or other
             claim where as provided by the Aircraft Lease Agreement dated as of

                                      87
<PAGE>

             would otherwise be liable to pay the Reinsured (subject to proof of
             loss), it being understood and agreed that any such payment by the
             Reinsurers will (to the extent of such payment) fully discharge and
             release the Reinsurers from any and all further liability in
             connection therewith"; subject to such provisions not contravening
             any law of the State of Incorporation;

      (x)    contain a provision entitling Lessor, or any insured party to
             initiate a claim under any policy in the event of the refusal or
             failure of Lessee to do so; and

      agreed.  In the event (a) Lessee is unwilling or unable to accept delivery
      of the Aircraft on the date notified by Lessor as the Delivery Date, and
      (b) the Aircraft meets Delivery Condition Requirements then Lessee's
      obligation to pay Rent hereunder shall commence on such Delivery Date

      Schedule 2 and a duly completed and executed Lease Supplement No. 1 in the
      form of Schedule 6 hereto and by authorizing the filing at the FAA of an
      executed copy of such Lease Supplement with an executed copy of this
      Agreement attached thereto.

4.3   Delayed Delivery: If owing to:-

(a)   any seller, manufacturer or existing lessee of the Aircraft delaying in
      the delivery of, or failing to deliver, the Aircraft to Lessor for any
      reason (other than because of any default of Lessor in the performance of
      its obligations under an agreement with that seller, manufacturer or
      lessee unless the default arises from any act or omission of Lessee)
      whether or not in circumstances entitling that seller, manufacturer or
      lessee to terminate that agreement;

(b)   any purchase agreement for the Aircraft terminating prior to delivery of
      the Aircraft (other than because of any default of Lessor in the
      performance of its obligations under that agreement unless the default
      arises from any act or omission of Lessee);

(c)   any Excusable Delay; or

(d)   notification of any defect or non-conformity pursuant to Clause 4.5;

      Lessor delays in the delivery of, or fails to deliver, the Aircraft under

<PAGE>
 
      (i)  Lessor will not be responsible for any losses, including loss of
           profit, costs or expenses arising from or in connection with the
           delay or failure suffered or incurred by Lessee;

      (ii) subject to Clause 4.5, Lessee will not be entitled to terminate this
           Agreement or to reject the Aircraft when tendered for delivery by
           Lessor, on the grounds of any such delay;

     (iii) in the case of termination of a purchase agreement, Lessor may at
           any time after the termination terminate this Agreement; and

      (iv) upon any such termination or termination pursuant to Clause 4.5
           neither Lessor nor Lessee will have any further obligation to the
           other under this Agreement other than as expressly set out in this
           Agreement, except that Lessor will repay to Lessee the Deposit and
           shall return the warrant certificate representing the Warrant.

4.4   Licenses: Lessee will at its expense obtain all licenses, permits and
      approvals which may be necessary to export the Aircraft from the Delivery
      Location. Lessor will furnish such data and information as may be
      reasonably requested by Lessee in connection with obtaining any such
      license, permit or approval.

4.5   Inspection: Prior to the Delivery Date, subject to any applicable purchase
      or lease agreement, Lessor will give Lessee an opportunity:-

(a)   to inspect the Aircraft at the Delivery Location; and

(b)   to assign up to 2 representatives to participate as observers in a
      demonstration flight to demonstrate the condition of the Aircraft.

      If Lessee notifies Lessor promptly prior to the Delivery Date of any
      defect or non-conformity with Schedule 1 observed during the inspection or
      demonstration flight, Lessor will correct or procure the correction of the
      defect or non-conformity as promptly as practicable (except to the extent
      otherwise agreed or to the extent in the opinion of Lessor it is
      impracticable or prohibitively expensive to do so).  Subject to Clause
      4.3, Lessor may postpone the Delivery Date in such a case to the date
      which Lessor notifies Lessee that the defect or non-conformity has been
      rectified.  Lessee will be entitled to terminate this Agreement if Lessor
      notifies it that Lessor does not intend to correct the defect or non-
      conformity.

4.6   Indemnity: Lessee will indemnify and hold harmless the Indemnitees from
      and against all Claims (as defined in Clause 10) arising from death or
      injury to any observer or any employee of Lessee in connection with any
      demonstration flight or inspection of the Aircraft by Lessee.

      extent otherwise required by Law, and if any such withholding is so
      required, Lessee shall pay on an After-Tax Basis an additional amount such
      that after the deduction of all amounts required to be withheld, the net
      amount actually received by Lessor on an After-Tax Basis will equal the

      withholding had not been required; provided, however, that if Lessee pays
      any such additional amount to compensate for the withholding of any Lessor
      Tax, Lessor shall repay to Lessee within 30 days after receipt of Lessee's
      written request therefor (which request shall include a description in

            applicable Law.  After any payment by Lessee of any Tax directly to
            a taxing authority, Lessee shall furnish to Lessor, on request, a
            certified copy of a receipt for Lessee's payment of such Tax or such
            other evidence of payment of such Tax as is reasonably obtainable by
            Lessee and reasonably acceptable to Lessor.

      (iii) Any amount payable by Lessee to an Indemnitee pursuant to Clause
            5.7 shall be paid within ten days after receipt of a written demand
            therefor from the relevant Indemnitee accompanied by a written

            with respect to such Tax under Clause 5.12 shall , at Lessee's
            election, be deferred until the date the contest has been completed.

5.8.  Sales and Use Taxes:

(a)   Lessee shall pay to Lessor (or, if permitted by applicable Law and if
      requested by Lessor, Lessee shall pay to the relevant tax authority for
      the account of Lessor), in addition to the amounts specified as "Rent" in
      Letter Agreement No. 1:

      (i)   all sales, use, rental, value added, goods and services and similar
            taxes ("Sales Taxes") required to be paid to the tax authority of

            the jurisdiction in which the Aircraft is habitually based with
            respect to the lease of the Aircraft to Lessee pursuant to the
            Operative Documents unless Lessee delivers to Lessor on or prior to
            the Delivery Date such exemption certificate or other document as
            may be acceptable to Lessor to evidence Lessee's entitlement to
            exemption from all Sales Taxes imposed by such jurisdiction with
            respect to the lease of the Aircraft pursuant to the Operative
            Documents; and

      (ii)  all Sales Taxes required to be paid to the tax authority of any
            jurisdiction in which the Aircraft may be used, operated or
            otherwise located from time to time unless Lessee delivers to Lessor
            such exemption certificates or other documents as may be required by
            applicable Law to evidence Lessee's 

                                       28
<PAGE>
 
            entitlement to exemption from all Sales Taxes imposed by each such
            jurisdiction with respect to the lease of the Aircraft pursuant to
            the Operative Documents.

(b)   Lessee will cooperate with Lessor in connection with the preparation and
      filing of any exemption application or similar document that is reasonably
      necessary or desirable under applicable Law to avoid the imposition of any
      Sales Taxes with respect to the transactions contemplated by the Operative
      Documents.

(c)   The specific obligations with respect to sales and use taxes set forth in
      this Clause 5.8 are in addition to, and are not in substitution for, the
      Lessee's obligation to indemnify for sales and use taxes pursuant to
      Clause 5.7.

5.9   Information:

(a)   If Lessee is required by any applicable Law, or by any third party, to
      deliver any report or return in connection with any Taxes for which Lessee
      would be obligated to indemnify Lessor under the Operative Documents,
      Lessee will complete the same and, on request, supply a copy of the report
      or return to Lessor.

(b)   If any report, return or statement is required to be made by Lessor with
      respect to any Tax for which there is an indemnity obligation of Lessee
      under this Clause 5, Lessee will promptly notify Lessor of the requirement
      and:

      (i)   if permitted by applicable Law, make and timely file such
            report, return or statement (except for any report, return or
            statement that Lessor has notified Lessee that Lessor intends to
            prepare and file), prepare such return in such manner as will show
            the ownership of the Aircraft in Lessor if required or appropriate,
            and provide Lessor upon request a copy of each such report, return
            or statement filed by Lessee, or

      (ii)  if Lessee is not permitted by applicable Law to file any such
            report, return or statement, Lessee will prepare and deliver to
            Lessor a proposed form of such report, return or statement within a
            reasonable time prior to the time such report, return or statement
            is to be filed.

      Lessee will provide such information and documents as Lessor may
      reasonably request to enable Lessor to comply with its tax filing, audit
      and litigation obligations.

5.10  Indemnity Payments to be Made on an After-Tax Basis: Lessee agrees that,
      with respect to any payment or indemnity pursuant to Clause 5.7 (Tax
      Indemnity), Clause 5.8 (Sales and Use Taxes) or Clause 10 (Indemnity) to
      or for the benefit of any Indemnitee, Lessee's indemnity obligations shall
      include such amount as may be necessary to hold such Indemnitee harmless
      on an After-Tax Basis from all Taxes required to be paid by such
      Indemnitee with respect to such payment or indemnity (including any
      payments pursuant to this Clause 5.10), determined based on the assumption
      that at the time each such payment or indemnity is accrued by the relevant
      Indemnitee, such payment or indemnity will be subject to (i) United States
      Federal income tax at the highest marginal 

                                       29
<PAGE>
 
      statutory tax rate applicable to corporations, (ii) United States state
      and local income taxes at the composite of the highest marginal statutory
      tax rates applicable to the Indemnitee and (iii) income taxes (if any)
      imposed by countries outside the United States at the actual rates imposed
      on the relevant Indemnitee.

5.11  Default Interest: If Lessee fails to pay any amount payable under this
      Agreement on the due date, Lessee will pay on demand from time to time to
      Lessor interest (both before and after judgment) on that amount, from the
      due date to the date of payment in full by Lessee to Lessor, at the
      Interest Rate specified in Letter Agreement No. 1; provided, however, that
      in no event shall such rate exceed the maximum permitted by Law.  All such
      interest will be compounded monthly and calculated on the basis of the
      actual number of days elapsed in the month assuming a 30 day month and a
      360 day year.

5.12  Contest:

(a)   If an Indemnitee receives a written claim for any Tax for which Lessee
      would be required to pay an indemnity pursuant to Clause 5.7 or Clause
      5.8, such Indemnitee shall notify Lessee promptly of such claim, provided
      that any failure to provide such notice will not relieve Lessee of any
      indemnification obligation pursuant to Clause 5.7 or Clause 5.8.  If
      requested by Lessee in writing promptly after receipt of such Indemnitee's
      notice, such Indmenitee shall, upon receipt of indemnity satisfactory to
      it and at the expense of Lessee (including, without limitation, all costs,
      expenses, legal and accountants' fees and disbursements, and penalties,
      interest and additions to tax incurred in contesting such claim) in good
      faith contest or (if permitted by applicable Law) permit Lessee to contest
      such claim by (i) resisting payment thereof if practicable and
      appropriate, (ii) not paying the same except under protest if protest is
      necessary and proper, or (iii) if payment is made, using reasonable
      efforts to obtain a refund of such Taxes in appropriate administrative and
      judicial proceedings.  Such Indemnitee shall determine the method of any
      contest conducted by such Indemnitee and (in good faith consultation with
      Lessee) control the conduct thereof.  Lessee shall determine the method of
      any contest conducted by Lessee and (in good faith consultation with such
      Indemnitee) control the conduct thereof.  Lessee shall pay in full all
      payments of Rent and other amounts payable pursuant to the Operative
      Documents, without reduction for or on account of any Tax, while such
      contest is continuing.  Such Indemnitee shall not be required to contest,
      or to continue to contest, a claim for Taxes under this Clause 5.12 if (x)
      such contest would result in a risk of criminal penalties or of a sale,
      forfeiture or loss of, or the imposition of a Lien (other than a Permitted
      Lien) on, the Aircraft, or (y) Lessee shall not have furnished an opinion
      of independent tax counsel selected by such Indemnitee and reasonably
      satisfactory to Lessee, that a reasonable basis exists for such contest,
      or (z) a Default or an Event of Default shall be continuing (unless Lessee
      shall have provided security reasonably satisfactory to such Indemnitee
      securing Lessee's performance of its obligations under this Clause 5).  If
      such Indemnitee contests any claim for Taxes by making a payment and
      seeking a refund thereof, then Lessee shall advance to such Indemnitee, on
      an interest-free basis, an amount equal to the Taxes to be paid by such
      Indemnitee in connection with the contest and shall indemnify such
      Indemnitee on an After-Tax Basis for any adverse tax consequences to such
      Indemnitee of such interest-

                                       30
<PAGE>
 
      free advance. Upon the final determination of any contest pursuant to this
      Clause 5.12 in respect of any Taxes for which Lessee shall have made an
      advance to such Indemnitee in accordance with the immediately preceding
      sentence, the amount of Lessee's obligation shall be determined as if such
      advance had not been made; any indemnity obligation of Lessee to such
      Indemnitee under this Clause 5 and such Indemnitee's obligation to repay
      the advance will be satisfied first by setoff against each other, and any
      difference owing by either party shall be paid within ten days after such
      final determination.

(b)   If an Indemnitee obtains a refund of all or any part of any Taxes for
      which a full indemnity was paid by Lessee, such Indemnitee shall pay
      Lessee the amount of such refund, reduced by any Taxes imposed on such
      Indemnitee on receipt or accrual of such refund and increased by any Taxes
      saved by such Indemnitee by reason of the deductibility of such payment by
      such Indemnitee.  If, in addition to such refund, such Indemnitee receives
      an amount of interest on such refund, such Indemnitee shall pay to Lessee
      the portion of such interest which is fairly attributable to such refund,
      reduced by any Taxes imposed by such Indemnitee on receipt or accrual of
      such interest and increased by any Taxes saved by reason of the
      deductibility of such payment by such Indemnitee.  Such Indemnitee shall
      not be required to make any payment to Lessee pursuant to this Clause 5.12
      if, and for so long as, an Event of Default shall have occurred and be
      continuing.

(c)   Any Indemnitee in its sole discretion (by written notice to Lessee) may
      waive its rights to indemnification pursuant to Clause 5.7 with respect to
      any claim for any Tax and may refrain from contesting or continuing the
      contest of such claim, in which event Lessee shall have no obligation to
      indemnify such Indemnitee for the Taxes that are the subject of such
      claim.  If an Indmenitee agrees to a settlement of any contest conducted
      pursuant to this Clause 5.11 without the prior written consent of Lessee,
      which consent shall not be unreasonably withheld, then Lessor shall be
      deemed to have waived its rights to the indemnification provided for in
      Clause 5.7 with respect to the Tax liability accepted in such settlement.

5.13  Net Lease: This Agreement is a net lease.  Lessee's obligations under this
      Agreement are absolute and unconditional irrespective of any contingency
      whatsoever including (but not limited to):-

(a)   any right of set-off, counterclaim, recoupment, defense or other right
      which either party to this Agreement may have against the other;

(b)   any unavailability of the Aircraft for any reason, including, but not
      limited to, a requisition of the Aircraft or any prohibition or
      interruption of or interference with or other restriction against Lessee's
      use, operation or possession of the Aircraft;

(c)   any lack or invalidity of title or any other defect in title,
      airworthiness, merchantability, fitness for any purpose, condition,
      design, or operation of any kind or nature of the Aircraft for any
      particular use or trade, or for registration or documentation under the

                                       31
<PAGE>
 
      laws of any relevant jurisdiction, or any Event of Loss in respect of or
      any damage to the Aircraft;

(d)   any insolvency, bankruptcy, reorganization, arrangement, readjustment of
      debt, dissolution, liquidation or similar proceedings by or against Lessor
      or Lessee;

(e)   any invalidity or unenforceability or lack of due authorization of, or
      other defect in, this Agreement;

(f)   and Security Interests with respect to the Aircraft or Taxes; and/or

(g)   any other cause which but for this provision would or might otherwise have
      the effect of terminating or in any way affecting any obligation of Lessee
      under this Agreement.

5.14  Security

(a)   To the fullest extent permitted by Law and by way of continuing security
      Lessee as sole beneficial owner charges the Deposit and the Maintenance
      Reserves and all rights of Lessee to payment thereof and the debt
      represented thereby (the "Charged Monies") to Lessor by way of first fixed
      charge as security for Lessee's obligations and liabilities under this
      Agreement and the Other Agreements (the "Secured Liabilities").  Except as
      expressly permitted under this Agreement, Lessee will not be entitled to
      payment of the Charged Monies.  Lessee will not assign, transfer or
      otherwise dispose of all or part of its rights in the Charged Monies and
      it will enter into any additional documents and instruments necessary or
      advisable to evidence, create or perfect Lessor's rights to the Charged
      Monies;

(b)   If Lessee fails to comply with any provision of this Agreement or any
      Event of Default has occurred and is continuing, in addition to all rights
      and remedies accorded to Lessor elsewhere in this Agreement and under Law
      as a secured party in respect of the Charged Monies, Lessor may
      immediately or at any time thereafter, without prior notice to Lessee:-

      (i)   set-off all or any part of the Secured Liabilities against the
            liabilities of Lessor in respect of the Charged Monies;  or

      (ii)  apply or appropriate the Charged Monies in or towards the payment or
            discharge of the Secured Liabilities in such order as Lessor sees
            fit; and

(c)   If Lessor has exercised the set-off described in sub-clause (b) above,
      Lessee shall, following a demand in writing from Lessor, restore the
      Charged Monies to the level at which they stood immediately prior to such
      set-off.

6.    MANUFACTURER'S WARRANTIES

6.1   Assignment: Notwithstanding this Agreement, Lessor will remain entitled to
      the benefit of each warranty, express or implied, with respect to the
      Aircraft, any Engine or Part so 

                                       32
<PAGE>
 
      far as concerns any manufacturer, vendor, subcontractor or supplier.
      Except to the extent Lessor otherwise directs, Lessor hereby authorizes
      Lessee to pursue any claim thereunder in relation to defects affecting the
      Aircraft, any Engine or Part and Lessee agrees diligently to pursue any
      such claim which arises at its own cost. Lessee will notify Lessor
      promptly upon becoming aware of any such claim.

6.2   Proceeds: Except to the extent Lessor otherwise agrees in a particular
      case, all proceeds of any such claim will be paid directly to Lessor but
      if and to the extent that such claim relates:-

(a)   to defects affecting the Aircraft which Lessee has rectified; or

(b)   to compensation for loss of use of the Aircraft, an Engine or any Part
      during the Term; and

      provided no Default has occurred and is continuing the proceeds will be
      paid to Lessee by Lessor but in the case of (a) above only on receipt of
      evidence satisfactory to Lessor that Lessee has rectified the relevant
      defect.

6.3   Parts: Except to the extent Lessor otherwise agrees in a particular case,
      Lessee will procure that all engines, components, furnishings or equipment
      provided by the manufacturer, vendor, subcontractor or supplier in
      replacement of a defective Engine or Part pursuant to the terms of any
      warranty will be installed promptly by Lessee and that title thereto free
      of Security Interests vests in Lessor.  On installation each part will be
      deemed to be a Part.  In the case of a Replacement Engine, Lessee will
      satisfy and perform each of the conditions and covenants set forth in
      Clause 11.1(c), and upon satisfaction of such conditions, such Replacement
      Engine will be deemed an "Engine" for all purposes of this Agreement.

6.4   Agreement: To the extent any warranties relating to the Aircraft are made
      available under an agreement between any manufacturer, vendor,
      subcontractor or supplier and Lessee, this Clause 6 is subject to that
      agreement.  However Lessee will:-

(a)   pay the proceeds of any claim thereunder to Lessor to be applied pursuant
      to Clause 6.2 and pending such payment will hold the claim and the
      proceeds on trust for Lessor; and

(b)   Lessee will take all such steps as are necessary at the end of the Term to
      ensure the benefit of any of those warranties which have not expired are
      vested in Lessor.

7.    LESSOR'S COVENANTS

7.1   Quiet Enjoyment: Lessor will not interfere with the quiet use, possession
      and enjoyment of the Aircraft by Lessee but the exercise by Lessor of its
      rights under or in connection with this Agreement will not constitute such
      an interference.  Lessor will procure at Lessee's request an undertaking
      of quiet enjoyment for the benefit of Lessee with respect to any
      prospective Lessor Lien.

                                       33

      repair of Quick Engine Change ("QEC") kits), the lesser of (i) the amount
      of that invoice and (ii) the amount equal to the aggregate amount of
      Engine Refurbishment Reserves paid in respect of that Engine under this

      and

(d)   with respect to the Landing Gear, the performance in accordance with this
      Agreement, of all work on the landing gear in the nature of overhaul and

            warrant certificate, if not previously exercised, representing the
            Warrant.

      not to operate the Aircraft between Cuba and the United States; and

(j)   not use, operate, or locate the Aircraft, or cause suffer or permit the
      Aircraft to be used, operated or located during the Term in any manner not
      covered by the Insurances or in any area excluded from coverage by the
      Insurances or in any manner which would prejudice the interests of the
      Indemnitees in the Insurances, the Aircraft, any Engine or any Part.

8.4  Taxes and other Outgoings: Lessee will promptly pay:-

(a)   all license and registration fees, Taxes (other than Lessor Taxes) and
      other amounts of any nature imposed by any Government Entity with respect
      to the Aircraft, including without limitation the purchase, ownership,
      delivery, leasing, possession, use, operation, return, sale or other
      disposition of the Aircraft; and

(b)   all rent, fees, charges, Taxes (other than Lessor Taxes) and other amounts
      in respect of any premises where the Aircraft or any Part thereof is
      located from time to time;

      except to the extent that in the reasonable opinion of Lessor such payment
      is being contested in good faith by appropriate proceedings, in respect of
      which adequate resources have been provided by Lessee and non-payment of
      which does not give rise to any material likelihood of the Aircraft or any
      interest therein being sold, forfeited or otherwise lost or of criminal
      liability on the part of Lessor.

8.5   Sub-Leasing and Wet-Leasing: LESSEE WILL NOT, WITHOUT THE PRIOR WRITTEN
      CONSENT OF LESSOR, SUB-LEASE, WET LEASE OR PART WITH POSSESSION OF THE
      AIRCRAFT, THE ENGINES OR ANY PART EXCEPT THAT LESSEE MAY PART WITH
      POSSESSION (A) WITH RESPECT TO THE AIRCRAFT, THE ENGINES OR ANY PART TO
      THE RELEVANT MANUFACTURERS FOR TESTING OR SIMILAR PURPOSES OR TO THE
      AGREED MAINTENANCE PERFORMER FOR SERVICE, REPAIR, MAINTENANCE OR OVERHAUL
      WORK, OR ALTERATION, MODIFICATIONS OR ADDITIONS TO THE EXTENT REQUIRED OR

      (i)   in the case of an engine, it is an engine of the same model as, or
            an improved or advanced version of the Engine it replaces, which is
            in the same or better operating condition, has substantially similar
            hours available until the next scheduled checks, inspections,

            requirements of Clause 8.13(a);

      (ii)  it would result in an unreasonable disruption of the operation of
            the Aircraft and/or the business of Lessee to ground the Aircraft

            agreement or the holder of such Security Interest, as the case may
            be, has confirmed and acknowledged in writing to Lessor, in form and
            substance satisfactory to Lessor, that it will respect the interest

      all Security Interests. Lessee will at its own expense take all such steps
      and execute, and procure the execution of, all such instruments as Lessor
      may require and which are necessary to ensure that title so passes  to
      Lessor according to all applicable Laws.  At any time when requested by

8.18  Third Party: Lessee will procure that no person (other than Lessor) will
      act in any manner inconsistent with its obligations under this Agreement

9.    INSURANCE

9.1   Insurances: Lessee will maintain in full force during the Term, and
      thereafter as expressly required in this Agreement, insurances in respect
      of the Aircraft in form and substance satisfactory to Lessor (the
      "Insurances" which expression includes, where the context so admits, any
      relevant re-insurance(s)) through such brokers and with such insurers and
      having such deductibles and being subject to such exclusions as may be
      approved by Lessor from time to time. The Insurances will be effected
      either:-

(a)   on a direct basis with insurers of recognized standing who normally
      participate in aviation insurances in the leading international insurance
      markets and led by reputable underwriter(s) approved by Lessor; or

      recognized standing and acceptable to Lessor for a percentage acceptable
      to Lessor of all risks insured (the "Reinsurances").

9.2   Requirements: Lessor's current requirements as to required Insurances are
      as specified in this Clause and in Schedule 4. Lessor may from time to
      time stipulate other requirements for the Insurances so that the scope and
      level of cover is maintained in line with best industry practice and the
      interests of Lessor protected.

9.3   Change: If at any time Lessor wishes to revoke its approval of any
      insurer, reinsurer, insurance or reinsurance, Lessor and/or its brokers
      will consult with Lessee and Lessee's brokers (as for the time being
      approved by Lessor) regarding whether that approval should be revoked to
      protect the interests of the parties insured. If, following the
      consultation, Lessor considers that any change should be made, Lessee will
      then arrange or procure the arrangement of alternative cover satisfactory
      to Lessor.

9.4   Insurance Covenants: Lessee will:-

      may be flown, in so far as they affect or concern 

                                       46

      requirements compliance with which is necessary to ensure that (i) the
      Aircraft is not in danger of detention or forfeiture, (ii) the Insurances
      remain valid and in full force and effect, and (iii) the interests of the
      Indemnitees in the Insurances and the Aircraft or any Part are not thereby
      prejudiced;

      for any purpose or in any manner not covered by the Insurances or outside
      any geographical limit imposed by the Insurances;

(c)   comply with the terms and conditions of each policy of the Insurances and
      not do, consent or agree to any act or omission which:-

      (i)   invalidates or may invalidate the Insurances; or

      (ii)  renders or may render void or voidable the whole or any part of any
            of the Insurances; or

      (iii) brings any particular liability within the scope of an exclusion or
            exception to the Insurances;

(d)   not take out without the prior written approval of Lessor any insurance or
      reinsurance in respect of the Aircraft other than those required under
      this Agreement unless relating solely to hull total loss, business
      interruption, profit commission and deductible risk;

(e)   commence renewal procedures at least 30 days prior to expiry of any of the
      Insurances and provide to Lessor:-

      (i)   if requested by Lessor, a written status report of renewal
            negotiation 14 days prior to each expiry date;

      (ii)  telexed telecopy confirmation of completion of renewal prior to each
            expiry date; and

      (iii) certificates of insurance (and where appropriate certificates of
            reinsurance), and broker's (and any reinsurance brokers') letter of
            undertaking in a form acceptable to Lessor in English, detailing the
            coverage and confirming the insurers' (and any reinsurers')
            agreement to the specified insurance requirements of this Agreement
            within 7 days after each renewal date;

(f)   on request, provide to Lessor copies of documents or other information
      evidencing the Insurances;

(g)   on request, provide to Lessor evidence that the Insurance premiums have
      been paid;

(h)   not make any modification or alteration to the Insurances material and
      adverse to the interests of any of the Indemnitees;

                                       47
<PAGE>
 
(i)   be responsible for any deductible under the Insurances; and

(j)   provide any other insurance and reinsurance related information, or
      assistance, in respect of the Insurances as Lessor may reasonably require.

9.5   Failure to Insure: If Lessee fails to maintain the Insurances in
      compliance with this Agreement, each of the Indemnitees will be entitled
      but not bound, (without prejudice to any other rights of Lessor under this
      Agreement):-

(a)   to pay the premiums due or to effect and maintain insurances satisfactory
      to it or otherwise remedy Lessee's failure in such manner (including,
      without limitation to effect and maintain an "owner's interest" policy) as
      it considers appropriate. Any sums so expended by it will become
      immediately due and payable by Lessee to Lessor on an After-Tax Basis
      together with interest thereon at the rate specified in Clause 5.11, from
      the date of expenditure by it up to the date of reimbursement by Lessee;
      and

(b)   at any time while such failure is continuing to require the Aircraft to
      remain at any airport or to proceed to and remain at any airport
      designated by it until the failure is remedied to its satisfaction.

9.6   Continuing Indemnity: Lessee shall effect and maintain insurance after the
      Expiry Date with respect to its liability under the Indemnity in Clause 10
      for 2 years which provides for each Indemnitee to be named as additional
      insured.  Lessee's obligation in this Clause shall not be affected by
      Lessee ceasing to be lessee of the Aircraft and/or any of the Indemnitees
      ceasing to have any interest in respect of the Aircraft.

9.7   Application of Insurance Proceeds:-

      As between Lessor and Lessee:-

(a)   all insurance payments received as the result of an Event of Loss or
      Engine Event of Loss occurring during the Term will be paid to Lessor and
      Lessor will pay the balance of those amounts to Lessee after deduction of
      all amounts which may be or become payable by Lessee to Lessor under this
      Agreement (including under Clause 11.1(b));

(b)   all insurance proceeds of any property, damage or loss to the Aircraft,
      any Engine or any Part occurring during the Term not constituting an Event
      of Loss or Engine Event of Loss and in excess of the Damage Notification
      Threshold will be applied in payment (or to reimburse Lessee) for repairs
      or replacement property upon Lessor being satisfied that the repairs or
      replacement have been effected in accordance with this Agreement.
      Insurance proceeds in amounts below the Damage Notification Threshold may
      be paid by the insurer directly to Lessee. Any balance remaining may be
      retained by Lessor;

(c)   all insurance proceeds in respect of third party liability will, except to
      the extent paid by the insurers to the relevant third party, be paid to
      Lessor to be paid directly in satisfaction of the relevant liability or to
      Lessee in reimbursement of any payment so made; and

                                       48
<PAGE>
 
(d)   notwithstanding Clauses 9.7(a), (b) or (c), if at the time of the payment
      of any such insurance proceeds a Default has occurred and is continuing,
      all such proceeds will be paid to or retained by Lessor to be applied
      toward payment of any amounts which may be or become payable by Lessee in
      such order as Lessor sees fit or as Lessor may elect.

      To the extent insurance proceeds are paid to Lessee, Lessee agrees to
      comply with the foregoing provisions and apply or pay over such proceeds
      as so required.

10.   INDEMNITY

10.1  GENERAL:  LESSEE AGREES TO DEFEND, INDEMNIFY AND HOLD HARMLESS THE
      INDEMNITEES ON AN AFTER-TAX BASIS FROM AND AGAINST ANY AND ALL CLAIMS,
      PROCEEDINGS, LOSSES, LIABILITIES, SUITS, JUDGMENTS, COSTS, EXPENSES,
      PENALTIES OR FINES (EACH A "CLAIM") (REGARDLESS OF WHEN THE SAME IS MADE
      OR INCURRED, WHETHER DURING OR AFTER THE TERM (BUT NOT BEFORE)):-

      (A)   WHICH MAY AT ANY TIME BE SUFFERED OR INCURRED DIRECTLY OR INDIRECTLY
            AS A RESULT OF OR CONNECTED WITH THE POSSESSION, DELIVERY,
            PERFORMANCE, MANAGEMENT, OWNERSHIP, REGISTRATION, CONTROL,
            MAINTENANCE, CONDITION, SERVICE, REPAIR, OVERHAUL, LEASING, USE,
            OPERATION OR RETURN OF THE AIRCRAFT, ANY ENGINE OR PART (EITHER IN
            THE AIR OR ON THE GROUND) WHETHER OR NOT THE CLAIM MAY BE
            ATTRIBUTABLE TO ANY DEFECT IN THE AIRCRAFT, ANY ENGINE OR ANY PART
            OR TO ITS DESIGN, TESTING OR USE OR OTHERWISE, AND REGARDLESS OF
            WHEN THE SAME ARISES OR WHETHER IT ARISES OUT OF OR IS ATTRIBUTABLE
            TO ANY ACT OR OMISSION, NEGLIGENT OR OTHERWISE, OF ANY INDEMNITEE;

      (B)   WHICH ARISE OUT OF ANY ACT OR OMISSION WHICH INVALIDATES OR WHICH
            RENDERS VOIDABLE ANY OF THE INSURANCES; AND

      (C)   WHICH MAY AT ANY TIME BE SUFFERED OR INCURRED AS A CONSEQUENCE OF
            ANY DESIGN, ARTICLE OR MATERIAL IN THE AIRCRAFT, ANY ENGINE OR ANY
            PART OR ITS OPERATION OR USE CONSTITUTING AN INFRINGEMENT OF PATENT,
            COPYRIGHT, TRADEMARK, DESIGN OR OTHER PROPRIETARY RIGHT OR A BREACH
            OF ANY OBLIGATION OF CONFIDENTIALITY OWED TO ANY PERSON;

      BUT EXCLUDING ANY CLAIM IN RELATION TO A PARTICULAR INDEMNITEE TO THE
      EXTENT THAT THAT CLAIM IS COVERED PURSUANT TO ANOTHER INDEMNITY PROVISION
      OF THIS AGREEMENT OR TO THE 

                                       49
<PAGE>
 
      EXTENT IT ARISES SOLELY AS A RESULT OF THE GROSS NEGLIGENCE OR WILLFUL
      MISCONDUCT OF THAT INDEMNITEE, LESSOR TAXES OR A LESSOR LIEN.

10.2  Duration: The indemnities contained in this agreement will continue in
      full force following the end of the Term notwithstanding any breach or
      repudiation by Lessor or Lessee of this Agreement or any termination of
      the lease of the Aircraft hereunder.

11.   EVENTS OF LOSS

11.1

(a)   Pre-delivery: If an Event of Loss occurs prior to delivery of the Aircraft
      to Lessee, Lessor will have the option, exercisable by giving Lessee
      notice in writing, to substitute an alternative aircraft of the same
      manufacture, model, value and utility as the Aircraft. If Lessor exercises
      such option, Lessee shall be obliged to lease such substitute aircraft
      pursuant to the terms and conditions of this Agreement and such substitute
      aircraft shall constitute the Aircraft for all purposes of this Agreement.
      Lessor shall provide Lessee with details of the substitute aircraft as
      soon as may be practicable after the occurrence of the Event of Loss. If
      Lessor advises Lessee that Lessor does not wish to exercise such option,
      this Agreement will immediately terminate and except as expressly stated
      in this Agreement neither party will have any further obligation or
      liability under this Agreement other than pursuant to Clause 16.9 except
      that Lessor will return the Deposit to Lessee; and

(b)   Post-delivery: If an Event of Loss occurs after delivery of the Aircraft
      to Lessee, Lessee will pay the Agreed Value to Lessor on or prior to the
      earlier of (i) 5 Business Days after the Event of Loss and (ii) the date
      of receipt of insurance proceeds in respect of that Event of Loss. Subject
      to the rights of any insurers and reinsurers or other third party, upon
      irrevocable payment in full to Lessor of that amount and all other amounts
      which may be or become payable to Lessor under this Agreement, Lessor will
      without recourse or warranty (except as to Lessor's Liens) and without
      further act, be deemed to have transferred to Lessee all of Lessor's
      rights to any Engines and Parts not installed when the Event of Loss
      occurred, all on an as-is where-is basis, and will at Lessee's expense,
      execute and deliver such bills of sale and other documents and instruments
      as Lessee may reasonably request to evidence (on the public record or
      otherwise) the transfer and the vesting of Lessor's rights in such Engines
      and Parts in Lessee, free and clear of all rights of Lessor and Lessor
      Liens.

(c)   Engine Event of Loss: From the Delivery Date upon an Engine Event of Loss,
      Lessee shall give Lessor prompt written notice thereof and shall, within
      45 days after such occurrence, convey to Lessor, as replacement for the
      Engine suffering such event, title to a Replacement Engine.  Each
      Replacement Engine shall be free of all Security Interests and shall be in
      as good an operating condition as the Engine being replaced, assuming the
      Engine being replaced was in the condition and repair required by the
      terms hereof immediately prior to the Engine Event of Loss. Upon full
      compliance by Lessee with the 

                                       50
<PAGE>
 
      terms of this Clause 11.1(c), Lessor will transfer to Lessee title to the
      Engine which suffered the Engine Event of Loss. Prior to or at the time of
      any such conveyance, Lessee, at its own expense, will promptly (i) furnish
      Lessor with a full warranty bill of sale, in form and substance reasonably
      satisfactory to Lessor, with respect to such Replacement Engine; (ii)
      cause a lease supplement (in form and substance satisfactory to Lessor)
      subjecting such Replacement Engine to this Agreement, to be duly executed
      by Lessee, and recorded pursuant to applicable Law; (iii) furnish Lessor
      with such evidence of title to such Replacement Engine as Lessor may
      reasonably request; (iv) furnish Lessor with an opinion of Lessee's
      counsel to the effect that title to such Replacement Engine has been duly
      conveyed to Lessor subject to this Agreement, free and clear of all
      Security Interests, and that such Replacement Engine is duly leased
      hereunder; (v) furnish a certificate signed by a duly authorized financial
      officer or executive of Lessee certifying that, upon consummation of such
      replacement, no Event of Default will have occurred or be continuing; (vi)
      furnish Lessor with such documents as Lessor may reasonably request in
      connection with the consummation of the transactions contemplated by this
      Clause 11.1(c), in each case in form and substance satisfactory to Lessor;
      and (vii) furnish such Financing Statements incorporating the Replacement
      Engine as may be requested by Lessor. For all purposes hereof, each such
      Replacement Engine shall be deemed part of the property leased hereunder,
      shall be deemed an "Engine" as defined herein and shall be deemed part of
      the same Aircraft as was the Engine replaced thereof. No Engine Event of
      Loss covered by this Clause 11.1(c) shall result in any reduction in Rent
      or affect Lessee's obligation to pay Engine Maintenance Reserves or the
      amount thereof to be paid by Lessee.

      Lessee shall indemnify each Indemnitee on an After-Tax Basis for any
      adverse tax consequence to such Indemnitee of the replacement of one or
      more Engines pursuant to this Clause 11.1.

11.2  Substitute Aircraft:

(a)   Without prejudice to the provisions of Clause 11.1 (b), if an Event of
      Loss occurs after delivery of the Aircraft to Lessee, Lessor will have the
      option, exercisable by giving Lessee notice in writing, to substitute an
      alternative aircraft (the "Substitute Aircraft") of the same manufacture
      and model as the Aircraft and having a value, utility and condition equal
      to or greater than the Aircraft as at the date of occurrence of the Event
      of Loss which Substitute Aircraft will be leased by Lessor to Lessee for
      the remainder of the Term pursuant to the terms and conditions of this
      Agreement.  If Lessor exercises such option, the Substitute Aircraft will
      constitute the Aircraft for all purposes of this Agreement in respect of
      facts and circumstances arising after the date of delivery thereof to
      Lessee.  Lessor shall provide Lessee with details of the Substitute
      Aircraft as soon as may be practicable after the occurrence of the Event
      of Loss;

(b)   Lessor will use all reasonable endeavors to deliver the Substitute
      Aircraft to Lessee as soon as may be practicable following the date of
      occurrence of the Event of Loss but not later than 3 months after such
      date; and

                                       51
<PAGE>
 
(c)   Lessee agrees to enter into such documentation as Lessor may require in
      order to reflect the leasing of the Substitute Aircraft as aforesaid
      including, without limitation, documentation in respect of the Insurances.

      Lessee shall indemnify each Indemnitee on an After-Tax Basis for any
      adverse tax consequence to such Indemnitee of the replacement of the
      Aircraft or Airframe pursuant to this Clause 11.2.

11.3  Requisition: During any requisition for use or hire of the Aircraft, any
      Engine or Part which does not constitute an Event of Loss:-

(a)   the Rent and other charges payable under this Agreement will not be
      suspended or abated either in whole or in part, and Lessee will not be
      released from any of its other obligations under the Agreement (other than
      operational obligations with which Lessee is unable to comply solely by
      virtue of the requisition); and

(b)   so long as no Default has occurred and is continuing, Lessee will be
      entitled to any hire paid by the requisitioning authority in respect of
      the Term. Lessee will, as soon as practicable after the end of any such
      requisition, cause the Aircraft to be put into the condition required by
      this Agreement. Lessor will be entitled to all compensation payable by the
      requisitioning authority in respect of any change in the structure, state
      or condition of the Aircraft arising during the period of requisition, and
      Lessor will apply such compensation in reimbursing Lessee for the cost of
      complying with its obligations under this Agreement in respect of any such
      change, but so that, if any Default has occurred and is continuing, Lessor
      may apply the compensation or hire in or towards settlement of any amounts
      owing by Lessee under this Agreement.

12.   RETURN OF AIRCRAFT

12.1  Return: On the Expiry Date or redelivery of the Aircraft pursuant to
      Clause 13.2 or termination of the leasing of the Aircraft under this
      Agreement Lessee will, unless an Event of Loss has occurred, at its
      expense, redeliver the Aircraft and Aircraft Documents to Lessor at the
      Redelivery Location or such other airport as is mutually acceptable to the
      parties hereto, in accordance with the procedures and in compliance with
      the conditions set forth in Schedule 3, free and clear of all Security
      Interests and Permitted Liens (other than Lessor Liens) and in a condition
      qualifying for immediate certification of airworthiness by the FAA or as
      otherwise agreed by Lessor and Lessee, and, if requested by Lessor,
      thereupon cause the Aircraft to be deregistered by the Air Authority.

12.2  Final Inspection: Immediately prior to redelivery of the Aircraft, Lessee
      will make the Aircraft available to Lessor for inspection ("Final
      Inspection") in order to verify that the condition of the Aircraft
      complies with this Agreement. The Final Inspection will be long enough to
      permit Lessor to:-

(a)   inspect the Aircraft Documents;

                                       52
<PAGE>
 
(b)   inspect the Aircraft and uninstalled Parts;

(c)   inspect the Engines, including without limitation (i) a borescope
      inspection of (A) the low pressure and high pressure compressors and (B)
      turbine and combustion areas, (ii) engine condition runs and (iii) review
      of Engine trend monitoring data and technical log reports covering the
      last ninety (90) days of operation; and

(d)   perform a complete borescope inspection of the APU; and

(e)   observe a 2 hour demonstration flight (with Lessor's representatives as
      on-board observers).

12.3  Non-Compliance: To the extent that, at the time of Final Inspection, the
      condition of the Aircraft does not comply with this Agreement, Lessee will
      at Lessor's option:-

(a)   immediately rectify the non-compliance and to the extent the non-
      compliance extends beyond the Expiry Date, the Term will be automatically
      extended and this Agreement will remain in force until the non-compliance
      has been rectified with Lessee being obligated to pay Rent with respect to
      the period of such extension on a per diem basis; or

(b)   redeliver the Aircraft to Lessor and indemnify Lessor on an After-Tax
      Basis, and provide to Lessor's satisfaction cash as security for that
      indemnity, against the cost of putting the Aircraft into the condition
      required by this Agreement.

12.4  Redelivery: Upon redelivery Lessee will provide to Lessor, upon Lessor's
      request, all documents necessary to export the Aircraft from the Habitual
      Base (including, without limitation, a valid and subsisting export license
      for the Aircraft) and required in relation to the deregistration of the
      Aircraft with the Air Authority.

12.5  Acknowledgment: Provided Lessee has complied with its obligations under
      this Agreement, following redelivery of the Aircraft by Lessee to Lessor
      at the Redelivery Location, Lessor will deliver to Lessee an
      acknowledgment confirming that Lessee has redelivered the Aircraft to
      Lessor in accordance with this Agreement.

12.6  Maintenance Program:

(a)   Prior to the Expiry Date and upon Lessor's request, Lessee will provide
      Lessor or its agent reasonable access to the Agreed Maintenance Program
      and the Aircraft Documents in order to facilitate the Aircraft's
      integration into any subsequent operator's fleet; and

(b)   Lessee will, if requested by Lessor to do so, upon return of the Aircraft
      deliver to Lessor a certified true current and complete copy of the Agreed
      Maintenance Program. Lessor agrees that it will not disclose the contents
      of the Agreed Maintenance Program to any person or entity except to the
      extent necessary to monitor Lessee's compliance with this Agreement and/or
      to bridge the maintenance program for the Aircraft from the Agreed
      Maintenance Program to another program after the Expiry Date.

                                       53
<PAGE>
 
12.7  Fuel: Upon redelivery of the Aircraft to Lessor, an adjustment will be
      made in respect of fuel on board on the Delivery Date and the Expiry Date
      at the price then prevailing at the Redelivery Location.

13.   DEFAULT

13.1  Events:  Each of the following events will constitute an Event of Default
      and a repudiation (but not a termination) of this Agreement by Lessee
      (whether any such event or condition is voluntary or involuntary or occurs
      by operation of law or pursuant to or in compliance with any judgment,
      decree or order of any court or any order, rule or regulation of any
      Government Entity).  Lessee acknowledges that the occurrence of any Event
      of Default would represent a material default in the performance of its

(a)   Non-payment: Lessee fails to make any payment under this Agreement on the
      due date; or

(b)   Insurance: Lessee fails to comply with any provision of Clause 9 or any

      terminated or notice of cancellation is given in respect of any such
      insurance; or

(c)   Breach: Lessee fails to comply with any other provision of this Agreement
      and, if such failure is in the reasonable opinion of Lessor capable of
      remedy, the failure continues for 5 days after notice from Lessor to
      Lessee; or

(d)   Representation: any representation or warranty made (or deemed to be
      repeated) by Lessee in or pursuant to this Agreement or in any document or
      certificate or statement is or proves to have been incorrect in any
      material respect when made or deemed to be repeated; or

(e)   Cross Default:

      (i)   a final judgment for the payment of money not covered by insurance
            in excess of Two Hundred Fifty Thousand Dollars ($250,000), or final
            judgments for the payment of money not covered by insurance in
            excess of Two Hundred Fifty Thousand Dollars ($250,000) in the
            aggregate, shall be rendered against Lessee and the same shall
            remain undischarged for a period of ninety (90) days during which
            execution thereof shall not be effectively stayed by agreement of
            the parties involved, stayed by court order or adequately bonded; or

      (ii)  attachments or other Security Interests shall be issued or entered
            against substantially all of the property of Lessee and shall remain
            undischarged or unbonded for ninety (90) days except for Security
            Interests created in connection with monies borrowed or obligations
            agreed to by Lessee in the ordinary course of its business; or

                                       54
<PAGE>
 
      (iii) Lessee shall default in the payment of any sum which by itself is
            in excess of $100,000 or any sums which in aggregate exceed $250,000
            notwithstanding that any particular individual sum thereof does not
            exceed $100,000 of any one or more obligations for the payment of
            borrowed money, for the deferred purchase price of property or for
            the payment of rent or hire under any lease of aircraft when the
            same becomes due if such nonpayment results in or would permit an
            acceleration of such indebtedness, or Lessee shall default in the
            performance of any other term, agreement, or condition contained in
            any agreement or instrument under or by which any such obligation is
            created, evidenced or secured, if the effect of such default is to
            cause or permit such obligation to become due prior to its stated
            maturity; or

      (iv)  any event of default or termination event, howsoever described,
            occurs under the Other Agreements; or

      or registration with or declaration to any Government Entity in connection

      revoked, suspended, canceled, withdrawn, terminated or not renewed, or
      otherwise ceases to be in full force; or

            but which is installed on the Airframe, subject to the rights of the
            owner, lessor or secured party thereof) or cause it to be
            redelivered to Lessor at a location in the United States identified
            by Lessor (or such other location as Lessor may require) (the
            "Return Location"), by summary proceedings or otherwise, all without

            property, or otherwise, caused by such entry or taking, except

            is hereby irrevocably, by way of security for Lessee's obligations
            under this Agreement, appointed attorney for Lessee in causing the
            redelivery or in directing the pilots of Lessee or other pilots to

            authorizations necessary for taking that action; or

      (ii)  by serving notice require Lessee to redeliver the Aircraft to Lessor
            at Shannon International Airport, Ireland (or such other location as
            Lessor may require); and/or

(e)   sell at private or public sale, as Lessor may determine, or hold, use,
      operate or lease to others the Aircraft as Lessor in its sole discretion
      may determine, all free and clear of any rights of Lessee; and/or

(f)   whether or not Lessor shall have exercised, or shall thereafter at any
      time exercise, any of its rights under paragraph (a), paragraph (b),
      paragraph (c), paragraph (d), or paragraph (e) of this Clause 13.2,
      Lessor, by 30 days written notice to Lessee specifying a payment date, may
      demand that Lessee pay to Lessor, and Lessee shall pay to Lessor, 

                                       58

      on the payment date specified in such notice, as liquidated damages for
      loss of bargain and not as a penalty (in lieu of the Rent due for the
      period commencing after the date specified for payment in such notice),
      any unpaid Rent for the Aircraft and other amounts owing under this
      Agreement (prorated in the case of Rent on a daily basis) to and including
      the payment date specified in such notice, plus the amount, if any, by
      which the aggregate Rent for the remainder of the Term (determined without
      reference to any right of Lessor to terminate the leasing of the Aircraft,
      whether or not such right is exercised), discounted periodically (equal to
      installment frequency) to present worth at the interest rate of 4 percent
      (4%) per annum, exceeds the fair market rental value (determined pursuant
      to the Appraisal Procedure) of the Aircraft for the remainder of the Term,
      after discounting such fair market rental value periodically (equal to
      installment frequency) to present worth as of the payment date specified
      in such notice at the interest rate of 4 percent (4%) per annum; and/or

(g)   In the event that Lessor, pursuant to Clause 13.2(e) above, shall have
      relet the Aircraft under a lease which extends at least to the date upon
      which the Term for the Aircraft would have expired but for Lessee's
      default, Lessor, in lieu of exercising its rights under Clause 13.2(f)
      above with respect to the Aircraft, may, if it shall so elect, demand that
      Lessee pay Lessor, and Lessee shall pay Lessor, as liquidated damages for
      loss of bargain and not as a penalty (in lieu of the Rent for the Aircraft
      due after the time of reletting) any unpaid Rent for the Aircraft due up
      to the date of reletting and any other amounts owing under this Agreement,
      plus the amount, if any, by which the aggregate Rent for the Aircraft,
      which would otherwise have become due over the remainder of the Term
      (determined without reference to any right of Lessor to terminate the
      leasing of the Aircraft, whether or not such right is exercised),
      discounted periodically (equal to installment frequency) to present worth
      as of the date of reletting at the interest rate of 4 percent (4%) per
      annum, exceeds the aggregate basic rental payments to become due under the
      reletting from the date of such reletting to the date upon which the Term
      for the Aircraft would have expired but for Lessee's default, discounted
      periodically (equal to installment frequency) to present worth as of the
      date of the reletting at the interest rate of 4 percent (4%) per annum;
      and/or

(h)   in lieu of the remedies set forth in paragraphs (a), (c), (d), (e), (f),
      and (g) of this Clause 13.2, by 30 days written notice to Lessee
      specifying a payment date, Lessor may demand that Lessee pay to Lessor,
      and Lessee shall pay to Lessor on the payment date specified in such
      notice as liquidated damages for loss of bargain and not as a penalty (in
      lieu of the Rent due for the period commencing after the date specified
      for payment in such notice), any unpaid Rent for the Aircraft and other
      amounts payable under this Agreement (prorated in the case of Rent on a
      daily basis) to and including the payment date specified in such notice,
      plus an amount equaling the aggregate Rent for the remainder of the Term,
      discounted periodically (equal to installment frequency) to present worth
      at the interest rate of 4 per cent (4%) per annum;

(i)   draw upon the Deposit or the Maintenance Reserves and apply such amounts
      to amounts owing to Lessor hereunder.

      Lessee, for itself and for its successors and assigns, hereby agrees that,
      to the extent now or hereafter permitted by applicable Law,
      notwithstanding any provision of the Federal Bankruptcy Code as amended
      from time to time, the title of Lessor to the Aircraft and any right of
      Lessor to take possession of the Aircraft in compliance with the
      provisions of this Agreement, in each case, upon the occurrence and
      continuance of an Event of Default, shall not be affected by the
      provisions of the Federal Bankruptcy Code, as amended from time to time.

      In addition to the foregoing, Lessee shall be liable for any and all
      unpaid Rent and other amounts payable under this Agreement during or after
      the exercise of any of the aforementioned remedies, together with interest
      on such unpaid amounts at the Interest Rate set forth in Letter Agreement
      No. 1, and until satisfaction of all of Lessee's obligations to Lessor
      hereunder and (on an After-Tax Basis) for all reasonable legal fees and
      other reasonable costs and expenses incurred by Lessor by reason of the
      occurrence of any Event of Default or the exercise of Lessor's remedies
      with respect thereto, including all costs and expenses incurred in
      connection with the return of the Aircraft in accordance with the terms of
      Clause 12 hereof or in placing the Aircraft in the condition and with
      airworthiness certification as required by such Clause.

      In effecting any repossession, Lessor and its representatives and agents,
      to the extent permitted by Law, shall: (i) have the right to enter upon
      any premises where it reasonably believes the Aircraft, the Airframe, an
      Engine or Part to be located; (ii) not be liable, in conversion or
      otherwise, for the taking of any personal property of Lessee which is in
      or attached to the Aircraft, the Airframe, an Engine or Part which is
      repossessed; provided, however, that Lessor shall return to Lessee all
      personal property of Lessee or its passengers which was on the Aircraft at
      the time Lessor re-takes possession of the Aircraft; (iii) not be liable
      or responsible, in any manner, for any inadvertent damage or injury to any
      of Lessee's property in repossessing and holding the Aircraft, the
      Airframe, an Engine or Part, except for that caused by or in connection
      with Lessor's gross negligence or willful acts; (iv) have the right to
      maintain possession of and dispose of the Aircraft, the Airframe, an
      Engine or Part on any premises owned by Lessee or under Lessee's control;
      and (v) have the right to obtain a key to any premises at which the
      Aircraft, the Airframe, an Engine or Part may be located from the landlord
      or owner thereof.

      If reasonably required by Lessor, Lessee, at its sole expense, shall
      assemble and make the Aircraft, the Airframe, an Engine or Part available
      at a place designated by Lessor in accordance with Clause 12 hereof.
      Lessee hereby agrees that, in the event of the return to or repossession
      by Lessor of the Aircraft, the Airframe, an Engine or Part, any rights in
      any warranty (express or implied) previously assigned to Lessee or
      otherwise held by Lessee shall without further act, notice or writing be
      assigned or reassigned to Lessor, if assignable.  Lessee shall be liable
      to Lessor on an After-Tax Basis for all reasonable expenses,
      disbursements, costs and fees incurred in (i) repossessing, storing,
      preserving, shipping, maintaining, repairing and refurbishing the
      Aircraft, the Airframe, an Engine or Part to the condition required by
      Clause 12 hereof and (ii) preparing the Aircraft, the Airframe, an Engine
      or Part for sale or lease, advertising the sale or lease of the Aircraft,

                                       60
<PAGE>
 
      the Airframe, an  Engine or Part and selling or releasing the Aircraft,
      the Airframe, an Engine or Part.  Lessor is hereby authorized and
      instructed, at its option, to make reasonable expenditures which Lessor
      considers advisable to repair and restore the Aircraft, the Airframe, an
      Engine or Part to the condition required by Clause 12 hereof, all at
      Lessee's sole expense.

      At any public sale of the Aircraft, the Airframe, an Engine or Part
      pursuant to this Clause, Lessor may bid for and purchase such property and
      Lessee agrees that the amounts paid therefor shall be used in the
      computation contemplated herein.

      With the exception that the remedy in Clause 13.2(g) can be elected only
      if the remedy in Clause 13.2(f) is not elected and the remedy in Clause
      13.2(h) can be elected only in lieu of all other remedies save the
      remedies in Clauses 13.2(b) and 13.2(i), no remedy referred to in this
      Clause 13 is intended to be exclusive, but, to the extent permissible
      hereunder or under applicable Law, each shall be cumulative and in
      addition to any other remedy referred to above or otherwise available to
      Lessor at Law or in equity; and the exercise or beginning of exercise by
      Lessor of any one or more of such remedies shall not preclude the
      simultaneous or later exercise by Lessor of any or all of such other
      remedies; provided, however, that nothing in this Clause 13 shall be
      construed to permit Lessor to obtain a duplicate recovery of any element
      of damages to which Lessor is entitled.  No express or implied waiver by
      Lessor of any Default or Event of Default shall in any way be, or be
      construed to be, a waiver of any future or subsequent Default.

13.3  Deregistration: If an Event of Default occurs, Lessor may sell or
      otherwise deal with the Aircraft free and clear of any leasehold or other
      interest of Lessee as if this Agreement had never been made and Lessee
      will at the request of Lessor take all steps necessary to effect (if
      applicable) deregistration of the Aircraft and its export from the country
      where the Aircraft is for the time being situated and any other steps
      necessary to enable the Aircraft to be redelivered to Lessor in accordance
      with this Agreement including without limitation execution and filing of a
      certificate or other instrument of lease termination with the Air
      Authority and; Lessee hereby irrevocably and by way of security for its
      obligations under this Agreement appoints (which appointment is coupled
      with an interest) Lessor as its attorney to execute and deliver any
      documentation and to do any act or thing required in connection with the
      foregoing.

14.   ASSIGNMENT

14.1  Lessee's Assignment: LESSEE WILL NOT ASSIGN, TRANSFER (VOLUNTARILY OR
      INVOLUNTARILY BY OPERATION OF LAW OR OTHERWISE) OR CREATE OR PERMIT TO
      EXIST ANY SECURITY INTEREST OVER, ANY OF ITS RIGHTS UNDER THIS AGREEMENT.

14.2  Lessor's Assignment: Lessor may assign or transfer all or any of its
      rights under this Agreement and in the Aircraft.  In the case of an
      assignment other than by way of security, Lessor will be released from and
      will have no further obligation under this Agreement following the
      assignment of all its rights under this Agreement and the 

                                       61
<PAGE>
 
      assumption by the assignee or transferee of all of Lessor's obligations
      under this Agreement. Notwithstanding any such assignment, Lessor will
      remain entitled to the benefit of each indemnity and the liability
      insurances effected under this Agreement. Lessee will comply with all
      reasonable requests of Lessor, its successors and assigns in respect of
      any such assignment. Lessor will promptly notify Lessee of any assignment.

14.3  Transfer: If Lessor desires to effect any assignment or transfer of its
      rights and obligations under this Agreement, Lessee agrees to cooperate
      and take all such steps as Lessor may reasonably request to give the
      transferee the benefit of this Agreement and to acknowledge the release of
      Lessor from its obligations hereunder as of the time of such assignment or
      transfer.

15.   ILLEGALITY

      If it is or becomes unlawful in any jurisdiction for Lessor to give effect
      to any of its obligations as contemplated by this Agreement or to continue
      this Agreement, Lessor may by notice in writing to Lessee terminate the
      leasing of the Aircraft under this Agreement and Lessee will forthwith
      redeliver the Aircraft to Lessor in accordance with Clause 12. Without
      prejudice to the foregoing Lessor will consult in good faith with Lessee
      as to any steps which may be taken to restructure the transaction to avoid
      that unlawfulness but will be under no obligation to take any such steps.

16.   MISCELLANEOUS

16.1  Waivers, Remedies Cumulative: The rights of Lessor under this Agreement:-

      (i)   may be exercised as often as necessary;

      (ii)  are cumulative and not exclusive of its rights under any Law; and

      (iii) may be waived only in writing and specifically.

      Delay in exercising or non-exercise of any such right will not constitute
      a waiver of that right.

16.2  Delegation: Lessor may delegate to any person or persons all or any of the
      trusts, powers or discretions vested in it by these presents and any such
      delegation may be made upon such terms and conditions and subject to such
      regulations (including power to sub-delegate) as Lessor in its absolute
      discretion thinks fit.

16.3  Certificates: Save where expressly provided in this Agreement, any
      certificate or determination by Lessor as to any rate of interest or as to
      any other amount payable under this Agreement will, in the absence of
      manifest error, be conclusive and binding on Lessee.

16.4  Appropriation: If any sum paid or recovered in respect of the liabilities
      of Lessee under this Agreement is less than the amount then due, Lessor
      may apply that sum to amounts 

                                       62
<PAGE>
 
      due under this Agreement in such proportions and order and generally in
      such manner as Lessor may determine at its sole discretion.

16.5  Currency:

      Lessee acknowledges that the specification of Dollars in this Agreement is
      of the essence and that Dollars shall be the currency of account in any
      and all events.  Lessee waives any right it may have in any jurisdiction
      to pay any amount under this Agreement in a currency other than Dollars.

16.6  Set-off: Lessor may set off any matured obligation owed by Lessee under
      this Agreement, the Other Agreements to which Lessor is a party or under
      any other agreement between Lessor (or any affiliate or associate of
      Lessor) and Lessee (to the extent beneficially owned by Lessor) against
      any obligation (whether or not matured) owed by Lessor to Lessee,
      regardless of the place of payment or currency. If the obligations are in
      different currencies, Lessor may convert either obligation at the market
      rate of exchange available in New York or at its option London for the
      purpose of the set-off. If an obligation is unascertained or unliquidated,
      Lessor may in good faith estimate that obligation and set off in respect
      of the estimate, subject to the relevant party accounting to the other
      when the obligation is ascertained or liquidated. Lessor will not be
      obliged to pay any amounts to Lessee under this Agreement so long as any
      sums which are then due from Lessee under this Agreement, the Other
      Agreements or under any other agreement between Lessor (or any affiliate
      or associate of Lessor) and Lessee remain unpaid and any such amounts
      which would otherwise be due will fall due only if and when Lessee has
      paid all such sums except to the extent Lessor otherwise agrees or sets
      off such amounts against such payment pursuant to the foregoing.

16.7  Severability: If a provision of this Agreement is or becomes illegal,
      invalid or unenforceable in any jurisdiction, that will not affect:-

(a)   the legality, validity or enforceability in that jurisdiction of any other
      provision of this Agreement; or

(b)   the legality, validity or enforceability in any other jurisdiction of that
      or any other provision of this Agreement.

16.8  Remedy: If Lessee fails to comply with any provision of this Agreement,
      Lessor may, without being in any way obliged to do so or responsible for
      so doing and without prejudice to the ability of Lessor to treat the non-
      compliance as a Default or an Event of Default, effect compliance on
      behalf of Lessee, whereupon Lessee shall become liable to pay immediately
      any sums expended by Lessor together with all costs and expenses
      (including legal costs) in connection therewith.

16.9  Expenses: Whether or not the Aircraft is delivered to Lessee pursuant to
      this Agreement, Lessee will pay to Lessor on an After-Tax Basis on
      demand:-

                                       63

      (a)   all costs associated with perfecting Lessor's rights in the Aircraft
            and/or this Agreement in the State of Registration, the Habitual
            Base of the Aircraft (and other states as appropriate given the
            operation of the Aircraft), including (but not limited to) the
            provision of legal opinions, tax advice, stamp duties, translations
            and registrations, whether required by Lessor or Lessee.

      (b)   all expenses (including legal, professional, and out-of-pocket
            expenses) incurred or payable by Lessor related to any amendment to
            or extension of or other documentation in connection with, or the
            granting of any waiver or consent under this Agreement requested by
            Lessee or the monitoring of compliance by Lessee with this
            Agreement; and

<PAGE>

18.   SECTION 1110

      Lessee acknowledges that Lessor would not have entered into this Agreement
      unless it had available to it the benefits of a lessor under Section 1110
      of Title 11 of the United States Code.  Lessee covenants and agrees with
      Lessor that to better ensure the availability of such benefits, Lessee
      shall support any motion, petition or application filed by Lessor with any
      bankruptcy court having jurisdiction over Lessee, whereby Lessor seeks
      recovery of possession of the Aircraft under said Section 1110 and shall
      not in any way oppose such action by Lessor unless Lessee shall have
      complied with the requirements of said Section 1110 to be fulfilled in
      order to entitle Lessee to continued use and possession of the Aircraft
      hereunder.  In the event said Section 1110 is amended, or if it is
      repealed and another statute is enacted in lieu thereof, Lessor and Lessee
      agree to amend this Agreement and take such other action not inconsistent
      with this 

                                       69
<PAGE>
 
      Agreement as Lessor reasonably deems necessary so as to afford to Lessor
      the rights and benefits as such amended or substituted statute confers
      upon owners and lessors of aircraft similarly situated to Lessor.

19.   USURY LAWS:  The parties intend to contract in strict compliance with the
      usury Laws of the States of California and Colorado and, to the extent
      applicable, the United States of America.  Notwithstanding anything to the
      contrary in the Operative Documents, Lessee will not be obligated to pay
      any interest in excess of the maximum non-usurious interest rate, as in
      effect from time to time, which may by applicable Law be charged,
      contracted for, reserved, received or collected by Lessor in connection
      with the Operative Documents.  During any period of time in which the
      then-applicable highest lawful rate is lower than the rate specified in
      Clauses 5.11 or 13.2, interest will accrue and be payable at such highest
      lawful rate; however, if at later times such highest lawful rate is
      greater than the rate specified in Clauses 5.11 or 13.2, then Lessee will
      pay interest at the highest lawful rate until the aggregate amount of
      interest paid by Lessee equals the amount of interest that would have been
      payable in accordance with the interest rate specified in Clauses 5.11 or
      13.2.

20.   MODIFICATION OR REVISION:

      Neither this Agreement nor any term of this Agreement may be modified,
      rescinded, changed waived, discharged or terminated except by a writing
      signed by the party to be charged.  Lessor and Lessee acknowledge their
      agreement to the provision of this Clause 20 by their initials below: -

      Letter Agreement No. 1, or such other amount agreed by Lessor from time to
      time;

(b)   [HULL WAR AND ALLIED PERILS, being such risks excluded from the Hull All
      Risks Policy to the fullest extent available from the leading
      international insurance markets including confiscation and requisition by
      the State of Registration for the Agreed Value, however, when the Aircraft
      is being operated solely in or over the United States of America and/or
      Canada, coverage may be limited to such perils as are customarily insured
      by comparable airlines, operating similar equipment in similar
      circumstances;]

(c)   ALL RISKS (INCLUDING WAR AND ALLIED RISK except when on the ground or in
      transit other than by air) property insurance on all Engines and Parts
      when not installed on the Aircraft on an "agreed value" basis for their
      full replacement value and including engine test and running risks;

(d)   AIRCRAFT THIRD PARTY, PROPERTY DAMAGE, PASSENGER, BAGGAGE, CARGO AND MAIL
      AND AIRLINE GENERAL THIRD PARTY (INCLUDING PRODUCTS) LEGAL LIABILITY for a
      Combined Single Limit (Bodily Injury/Property Damage) of an amount not
      less than the Minimum Liability Coverage for the time being any one
      occurrence (but in respect of products and personal injury liability this
      limit may be an aggregate limit for any and all losses occurring during
      the currency of the policy). [War and Allied Risks are also to be covered
      under the Policy in  line with prudent market practice for comparable
      airlines, operating similar equipment in similar circumstances];

(e)   All required hull and spares insurance (as specified above), so far as it
      relates to the Aircraft will: -

      (i)   name Lessor and its successors and assigns as additional assureds
            for their respective rights and interests, warranted, each as to
            itself only, no operational interest;

      (ii)  provide that any loss will be settled jointly with Lessor and Lessee
            and will be payable in Dollars to Lessor except where the loss does
            not exceed the Damage Notification Threshold, and Lessor has not
            notified the insurers to the contrary, in which case the loss will
            be settled with and paid to Lessee;

                                       86
<PAGE>
 
      (iii) if separate Hull "all risks" and "war risks" insurances are
            arranged, include a 50/50 provision in accordance with market
            practice (AVS. 103 is the current market language);

      (iv)  confirm that the insurers are not entitled to replace the Aircraft
            in the event of an insured Event of Loss;

      (v)   confirm that the insurers will not obtain a valid discharge of the
            obligations under the Insurances by payment to the broker,
            notwithstanding market practice to the contrary;

(f)   All required liability insurances (specified above) will:-

      (i)   include Lessor, GECASI, GECASL and their respective successors and
            assigns and their respective shareholders, subsidiaries, directors,
            officers, agents, employees and indemnitees as additional insureds
            for their respective rights and interests, warranted, each as to
            itself only, no operational interest;

      (ii)  include a Severability of Interest Clause which provides that the

            issued to each assured;

      (iii)  contain a provision confirming that the policy is primary without
            right of contribution and the liability of the insurers will not be
            affected by any other insurance of which Lessor or Lessee have the
            benefit so as to reduce the amount payable to the additional
            insureds under such policies;

(g)  All Insurances will:-

      (i)   be in accordance with normal industry practice of persons operating
            similar aircraft in similar circumstances;

            assureds the Insurances will not be invalidated by any act or
            omission by Lessee, or any other person other than the respective
            additional assured seeking protection and shall insure the interests
            of each of the additional assureds regardless of any breach or
            violation by Lessee, or any other person other than the 

                                       87
<PAGE>
 
            respective additional assured seeking protection of any warranty,
            declaration or condition, contained in such Insurances;

      (vi)  provide that the insurers will hold harmless and waive any rights of
            recourse and/or subrogation against the additional assureds,
            including GECASI and GECASL or to be subrogated to any rights of
            Lessor against Lessee;

      (vii) provide that the additional assureds will have no obligation or
            responsibility for the payment of any premiums due (but reserve the
            right to pay the same should any of them elect so to do) and that
            the insurers will not exercise any right of set-off or counter-claim
            in respect of any premium due against the respective interests of
            the additional assureds other than outstanding premiums relating to
            the Aircraft, any Engine or Part the subject of the relevant claim;

      (viii)provide that the Insurances will continue unaltered for the
            benefit of the additional assureds for at least 30 days after
            written notice by registered mail or telex of any cancellation,
            change, event of non-payment of premium or installment thereof has
            been sent to Lessor, except in the case of war risks for which 7
            days (or such lesser period as is or may be customarily available in
            respect of war risks or allied perils) will be given, or in the case
            of war between the 5 great powers or nuclear peril for which
            termination is automatic;

      (ix)  if reinsurance is a requirement of this Agreement such reinsurance
            will (i) be on the same terms as the original insurances and will

      Risks Policy to the fullest extent available from the leading

      the State of Registration for the Agreed Value, however, when the Aircraft
      is being operated solely in or over the United States of America and/or
      Canada, coverage may be limited to such perils as are customarily insured
      by comparable airlines, operating similar equipment in similar
      circumstances;]

(c)   ALL RISKS (INCLUDING WAR AND ALLIED RISK except when on the ground or in
      transit other than by air) property insurance on all Engines and Parts

      AND AIRLINE GENERAL THIRD PARTY (INCLUDING PRODUCTS) LEGAL LIABILITY for a
      Combined Single Limit (Bodily Injury/Property Damage) of an amount not
      less than the Minimum Liability Coverage for the time being any one
      occurrence (but in respect of products and personal injury liability this
      limit may be an aggregate limit for any and all losses occurring during
      the currency of the policy). [War and Allied Risks are also to be covered
      under the Policy in  line with prudent market practice for comparable
      airlines, operating similar equipment in similar circumstances];

(e)   All required hull and spares insurance (as specified above), so far as it
      relates to the Aircraft will: -

      (i)   name Lessor and its successors and assigns as additional assureds

            not exceed the Damage Notification Threshold, and Lessor has not
            notified the insurers to the contrary, in which case the loss will
            be settled with and paid to Lessee;

      (i)   include Lessor, GECASI, GECASL and their respective successors and

            for their respective rights and interests, warranted, each as to
            itself only, no operational interest;

            issued to each assured;

      (iii) contain a provision confirming that the policy is primary without
            right of contribution and the liability of the insurers will not be
            affected by any other insurance of which Lessor or Lessee have the
            benefit so as to reduce the amount payable to the additional
            insureds under such policies;

            additional assured seeking protection and shall insure the interests
            of each of the additional assureds regardless of any breach or
            violation by Lessee, or any other person other than the 

                                       87

            Lessor against Lessee;

            the Aircraft, any Engine or Part the subject of the relevant claim;

      (viii)provide that the Insurances will continue unaltered for the

            change, event of non-payment of premium or installment thereof has
            been sent to Lessor, except in the case of war risks for which 7
            days (or such lesser period as is or may be customarily available in
            respect of war risks or allied perils) will be given, or in the case
            of war between the 5 great powers or nuclear peril for which
            termination is automatic;

3.2   Further conditions precedent: The obligations of Lessor to deliver and
      lease the Aircraft under this Agreement are subject to the further
      conditions precedent that:-

(a)   the representations and warranties of Lessee under Clauses 2.1 and 2.2 are
      correct and would be correct if repeated on delivery of the Aircraft under
      this Agreement; and

(b)   no Default has occurred and is continuing or might result from the leasing
      of the Aircraft to Lessee under this Agreement.

3.3   Waiver:  The conditions specified in Clauses 3.1 and 3.2 are for the sole
      benefit of Lessor and may be waived or deferred in whole or in part and
      with or without conditions 

                                      23
<PAGE>
 
      by Lessor. If any of those conditions are not satisfied on the Delivery
      Date and Lessor (in its absolute discretion) nonetheless agrees to deliver
      the Aircraft to Lessee, Lessee will ensure that those conditions are
      fulfilled within 15 days after the Delivery Date and Lessor may treat as
      an Event of Default the failure of Lessee to do so.

4.    COMMENCEMENT

4.1   Leasing: Lessor will lease the Aircraft to Lessee and Lessee will take the
      Aircraft on lease in accordance with this Agreement for the duration of
      the Term. Lessor will deliver and Lessee will accept the Aircraft on the
      day in the Scheduled Delivery Month notified by Lessor to Lessee at least
      5 Business Days in advance of such date or such other day as may be
      agreed.  In the event (a) Lessee is unwilling or unable to accept delivery
      of the Aircraft on the date notified by Lessor as the Delivery Date, and
      (b) the Aircraft meets Delivery Condition Requirements then Lessee's
      obligation to pay Rent hereunder shall commence on such Delivery Date
      notwithstanding that Lessee has not accepted possession of the Aircraft.
      After delivery the Aircraft and every Part will be in every respect at the
      sole risk of Lessee, who will bear all risk of loss, theft, damage or
      destruction to the Aircraft from any cause whatsoever.

4.2   Delivery: The Aircraft will be delivered to and accepted by Lessee at the
      Delivery Location or such other location as may be agreed. Lessee will
      effect acceptance of the Aircraft by execution and delivery to Lessor of
      the duly completed and executed Certificate of Acceptance in the form of
      Schedule 2 and a duly completed and executed Lease Supplement No. 1 in the
      form of Schedule 6 hereto and by authorizing the filing at the FAA of an
      executed copy of such Lease Supplement with an executed copy of this
      Agreement attached thereto.

4.3   Delayed Delivery: If owing to:-

(a)   any seller, manufacturer or existing lessee of the Aircraft delaying in
      the delivery of, or failing to deliver, the Aircraft to Lessor for any
      reason (other than because of any default of Lessor in the performance of
      its obligations under an agreement with that seller, manufacturer or
      lessee unless the default arises from any act or omission of Lessee)
      whether or not in circumstances entitling that seller, manufacturer or
      lessee to terminate that agreement;

(b)   any purchase agreement for the Aircraft terminating prior to delivery of
      the Aircraft (other than because of any default of Lessor in the
      performance of its obligations under that agreement unless the default
      arises from any act or omission of Lessee);

(c)   any Excusable Delay; or

(d)   notification of any defect or non-conformity pursuant to Clause 4.5;

      Lessor delays in the delivery of, or fails to deliver, the Aircraft under
      this Agreement:-

                                      24
<PAGE>
 
      (i)    Lessor will not be responsible for any losses, including loss of
             profit, costs or expenses arising from or in connection with the
             delay or failure suffered or incurred by Lessee;

      (ii)   subject to Clause 4.5, Lessee will not be entitled to terminate 
             this Agreement or to reject the Aircraft when tendered for delivery
             by Lessor, on the grounds of any such delay;

      (iii)  in the case of termination of a purchase agreement, Lessor may at
             any time after the termination terminate this Agreement; and

      (iv)   upon any such termination or termination pursuant to Clause 4.5
             neither Lessor nor Lessee will have any further obligation to the
             other under this Agreement other than as expressly set out in this
             Agreement, except that Lessor will repay to Lessee the Deposit and
             shall return the warrant certificate representing the Warrant.

4.4  Licenses: Lessee will at its expense obtain all licenses, permits and
     approvals which may be necessary to export the Aircraft from the Delivery
     Location. Lessor will furnish such data and information as may be
     reasonably requested by Lessee in connection with obtaining any such
     license, permit or approval.

4.5  Inspection: Prior to the Delivery Date, subject to any applicable purchase
     or lease agreement, Lessor will give Lessee an opportunity:-

(a)  to inspect the Aircraft at the Delivery Location; and

(b)  to assign up to 2 representatives to participate as observers in a
     demonstration flight to demonstrate the condition of the Aircraft.

     If Lessee notifies Lessor promptly prior to the Delivery Date of any
     defect or non-conformity with Schedule 1 observed during the inspection or
     demonstration flight, Lessor will correct or procure the correction of the
     defect or non-conformity as promptly as practicable (except to the extent
     otherwise agreed or to the extent in the opinion of Lessor it is
     impracticable or prohibitively expensive to do so).  Subject to Clause
     4.3, Lessor may postpone the Delivery Date in such a case to the date
     which Lessor notifies Lessee that the defect or non-conformity has been
     rectified.  Lessee will be entitled to terminate this Agreement if Lessor
     notifies it that Lessor does not intend to correct the defect or non-
     conformity.

4.6  Indemnity: Lessee will indemnify and hold harmless the Indemnitees from and
     against all Claims (as defined in Clause 10) arising from death or injury
     to any observer or any employee of Lessee in connection with any
     demonstration flight or inspection of the Aircraft by Lessee.

      Rental Period shall be paid on the Business Day immediately preceding the
      date on which such Rental Period commences.

              Agreement No. 1 and the number of Engine Flight Hours (or fraction
              thereof) operated by the Engine during that calendar month 
              ("Engine LLP Refurbishment Reserves"); and

              the Engine Refurbishment Reserve Rate specified in Letter
              Agreement No. 1 and the number of Engine Flight Hours (or fraction
              thereof) operated by the Engine during that calendar month
              ("Engine Refurbishment Reserves"); and

              month ("Landing Gear Maintenance Reserves").

(b)   Adjustment: Lessor may adjust the amount of Maintenance Reserves after 
      the Delivery Date upon notice to Lessee not more frequently than annually
      utilizing the Escalation Adjustment set forth in Letter Agreement No. 1.
      The Engine Reserve Rate may be further adjusted not more frequently than
      annually as provided in Section III of Letter Agreement No. 1.
       
5.5   Payments: All payments by Lessee to Lessor under this Agreement will be
      made for value on the due date in Dollars and in same day funds settled
      through the New York Clearing House System or such other funds as may for
      the time being be customary for the settlement in New York City of
      international payments in Dollars by telegraphic transfer to Bank of
      America, San Francisco, California, ABA No. 121-000-358, Account No.
      14993-03400 or to such other account as Lessor may advise Lessee in
      writing.

5.6   Withholding: All payments by Lessee pursuant to the Operative Documents
      shall be free of all withholdings of any nature whatsoever except to the
      extent otherwise required by Law, and if any such withholding is so
      required, Lessee shall pay on an After-Tax Basis an additional amount such
      that after the deduction of all amounts required to be withheld, the net
      amount actually received by Lessor on an After-Tax Basis will equal the
      amount that Lessor would have received on an After-Tax Basis if such
      withholding had not been required; provided, however, that if Lessee pays
      any such additional amount to compensate for the withholding of any Lessor
      Tax, Lessor shall repay to Lessee within 30 days after receipt of Lessee's
      written request therefor (which request shall include a description in
      reasonable detail of the Lessor Tax involved and the calculation of the
      additional amount to be repaid) the amount of such additional amount to
      the extent attributable to any Lessor Tax.

5.7   General Tax Indemnity:

      General:

      (i)   Lessee will on demand pay and indemnify each Indemnitee against all
            Taxes (other than Lessor Taxes) levied or imposed against or upon or
            payable by such Indemnitee or Lessee and arising from, with respect
            to or in connection with the transactions pursuant to the Operative
            Documents (except for the Warrant and the side letter dated as of
            April 3, 1996 specifically relating thereto, but save in so far as
            any indemnity by Lessee in respect of Taxes is 

                                      27
<PAGE>
 
             specifically provided for therein, including (but not limited to)
             all Taxes relating or attributable to Lessee, any Operative
             Document or the Aircraft directly or indirectly in connection with
             the importation, exportation, registration, ownership, leasing, 
             sub-leasing, purchase, delivery, possession, use, operation,
             repair, maintenance, overhaul, transportation, landing, storage,
             presence or redelivery of the Aircraft or any part thereof or any
             rent, receipts, insurance proceeds, income or other amounts arising
             therefrom.

      (ii)   All Taxes indemnified pursuant to this Clause 5.7 shall be paid by
             Lessee directly to the appropriate taxing authority (to the extent
             permitted by applicable Law) at or before the time prescribed by
             applicable Law.  After any payment by Lessee of any Tax directly to
             a taxing authority, Lessee shall furnish to Lessor, on request, a
             certified copy of a receipt for Lessee's payment of such Tax or
             such other evidence of payment of such Tax as is reasonably
             obtainable by Lessee and reasonably acceptable to Lessor.

      (iii)  Any amount payable by Lessee to an Indemnitee pursuant to Clause
             5.7 shall be paid within ten days after receipt of a written demand
             therefor from the relevant Indemnitee accompanied by a written
             statement describing in reasonable detail the basis for such
             indemnity and the computation of the amount so payable, provided
             that if an amount of any indemnified Tax is being contested in
             accordance with Clause 5.12 and Lessee shall have duly performed
             (and shall continue to perform) all its obligations under Clause
             5.12 with respect to such contest, then payment of the indemnity
             with respect to such Tax under Clause 5.12 shall , at Lessee's
             election, be deferred until the date the contest has been 
             completed.

5.8.  Sales and Use Taxes:

(a)   Lessee shall pay to Lessor (or, if permitted by applicable Law and if
      requested by Lessor, Lessee shall pay to the relevant tax authority for
      the account of Lessor), in addition to the amounts specified as "Rent" in
      Letter Agreement No. 1:

      (i)    all sales, use, rental, value added, goods and services and similar
             taxes ("Sales Taxes") required to be paid to the tax authority of
             the jurisdiction in which the Delivery Location is situated or to
             the jurisdiction in which the Aircraft is habitually based with
             respect to the lease of the Aircraft to Lessee pursuant to the
             Operative Documents unless Lessee delivers to Lessor on or prior to
             the Delivery Date such exemption certificate or other document as
             may be acceptable to Lessor to evidence Lessee's entitlement to
             exemption from all Sales Taxes imposed by such jurisdiction with
             respect to the lease of the Aircraft pursuant to the Operative
             Documents; and

      (ii)   all Sales Taxes required to be paid to the tax authority of any
             jurisdiction in which the Aircraft may be used, operated or
             otherwise located from time to time unless Lessee delivers to
             Lessor such exemption certificates or other 

                                      28
<PAGE>
 
             documents as may be required by applicable Law to evidence Lessee's
             entitlement to exemption from all Sales Taxes imposed by each such
             jurisdiction with respect to the lease of the Aircraft pursuant to
             the Operative Documents.

(b)   Lessee will cooperate with Lessor in connection with the preparation and
      filing of any exemption application or similar document that is reasonably
      necessary or desirable under applicable Law to avoid the imposition of any
      Sales Taxes with respect to the transactions contemplated by the Operative
      Documents.

(c)   The specific obligations with respect to sales and use taxes set forth in
      this Clause 5.8 are in addition to, and are not in substitution for, the
      Lessee's obligation to indemnify for sales and use taxes pursuant to
      Clause 5.7.

5.9   Information:

(a)   If Lessee is required by any applicable Law, or by any third party, to
      deliver any report or return in connection with any Taxes for which Lessee
      would be obligated to indemnify Lessor under the Operative Documents,
      Lessee will complete the same and, on request, supply a copy of the report
      or return to Lessor.

(b)   If any report, return or statement is required to be made by Lessor with
      respect to any Tax for which there is an indemnity obligation of Lessee
      under this Clause 5, Lessee will promptly notify Lessor of the requirement
      and:

      (i)   if permitted by applicable Law, make and timely file such
            report, return or statement (except for any report, return or
            statement that Lessor has notified Lessee that Lessor intends to
            prepare and file), prepare such return in such manner as will show
            the ownership of the Aircraft in Lessor if required or appropriate,
            and provide Lessor upon request a copy of each such report, return
            or statement filed by Lessee, or

      (ii)  if Lessee is not permitted by applicable Law to file any such
            report, return or statement, Lessee will prepare and deliver to
            Lessor a proposed form of such report, return or statement within a
            reasonable time prior to the time such report, return or statement
            is to be filed.

      Lessee will provide such information and documents as Lessor may
      reasonably request to enable Lessor to comply with its tax filing, audit
      and litigation obligations.

5.10  Indemnity Payments to be Made on an After-Tax Basis: Lessee agrees that,
      with respect to any payment or indemnity pursuant to Clause 5.7 (Tax
      Indemnity), Clause 5.8 (Sales and Use Taxes) or Clause 10 (Indemnity) to
      or for the benefit of any Indemnitee, Lessee's indemnity obligations shall
      include such amount as may be necessary to hold such Indemnitee harmless
      on an After-Tax Basis from all Taxes required to be paid by such
      Indemnitee with respect to such payment or indemnity (including any
      payments pursuant to this Clause 5.10), determined based on the assumption
      that at the time each such payment or indemnity accrues to the relevant
      Indemnitee, such payment or 

                                      29
<PAGE>
 
      indemnity will be subject to (i) United States Federal income tax at the
      highest marginal statutory tax rate applicable to corporations, (ii)
      United States state and local income taxes at the composite of the highest
      marginal statutory tax rates applicable to the Indemnitee and (iii) income
      taxes (if any) imposed by countries outside the United States at the
      actual rates imposed on the relevant Indemnitee.

5.11  Default Interest: If Lessee fails to pay any amount payable under this
      Agreement on the due date, Lessee will pay on demand from time to time to
      Lessor interest (both before and after judgment) on that amount, from the
      due date to the date of payment in full by Lessee to Lessor, at the
      Interest Rate specified in Letter Agreement No. 1; provided, however, that
      in no event shall such rate exceed the maximum permitted by Law.  All such
      interest will be compounded monthly and calculated on the basis of the
      actual number of days elapsed in the month assuming a 30 day month and a
      360 day year.

5.12  Contest:

(a)   If an Indemnitee receives a written claim for any Tax for which Lessee
      would be required to pay an indemnity pursuant to Clause 5.7 or Clause
      5.8, such Indemnitee shall notify Lessee promptly of such claim, provided
      that any failure to provide such notice will not relieve Lessee of any
      indemnification obligation pursuant to Clause 5.7 or Clause 5.8.  If
      requested by Lessee in writing promptly after receipt of such Indemnitee's
      notice, such Indemnitee shall, upon receipt of indemnity satisfactory to
      it and at the expense of Lessee (including, without limitation, all costs,
      expenses, legal and accountants' fees and disbursements, and penalties,
      interest and additions to tax incurred in contesting such claim) in good
      faith contest or (if permitted by applicable Law) permit Lessee to contest
      such claim by (i) resisting payment thereof if practicable and
      appropriate, (ii) not paying the same except under protest if protest is
      necessary and proper, or (iii) if payment is made, using reasonable
      efforts to obtain a refund of such Taxes in appropriate administrative and
      judicial proceedings.  Such Indemnitee shall determine the method of any
      contest conducted by such Indemnitee and (in good faith consultation with
      Lessee) control the conduct thereof.  Lessee shall determine the method of
      any contest conducted by Lessee and (in good faith consultation with such
      Indemnitee) control the conduct thereof.  Lessee shall pay in full all
      payments of Rent and other amounts payable pursuant to the Operative
      Documents, without reduction for or on account of any Tax, while such
      contest is continuing.  Such Indemnitee shall not be required to contest,
      or to continue to contest, a claim for Taxes under this Clause 5.12 if (x)
      such contest would result in a risk of criminal penalties or of a sale,
      forfeiture or loss of, or the imposition of a Lien (other than a Permitted
      Lien) on, the Aircraft, or (y) Lessee shall not have furnished an opinion
      of independent tax counsel selected by such Indemnitee and reasonably
      satisfactory to Lessee, that a reasonable basis exists for such contest,
      or (z) a Default or an Event of Default shall be continuing (unless Lessee
      shall have provided security reasonably satisfactory to such Indemnitee
      securing Lessee's performance of its obligations under this Clause 5).  If
      such Indemnitee contests any claim for Taxes by making a payment and
      seeking a refund thereof, then Lessee shall advance to such Indemnitee, on
      an interest-free basis, an amount equal to the Taxes to be paid by such
      Indemnitee in connection with the contest and shall indemnify such
      Indemnitee on an 

                                      30
<PAGE>
 
      After-Tax Basis for any adverse tax consequences to such Indemnitee of
      such interest-free advance. Upon the final determination of any contest
      pursuant to this Clause 5.12 in respect of any Taxes for which Lessee
      shall have made an advance to such Indemnitee in accordance with the
      immediately preceding sentence, the amount of Lessee's obligation shall be
      determined as if such advance had not been made; any indemnity obligation
      of Lessee to such Indemnitee under this Clause 5 and such Indemnitee's
      obligation to repay the advance will be satisfied first by setoff against
      each other, and any difference owing by either party shall be paid within
      ten days after such final determination.

(b)   If an Indemnitee obtains a refund of all or any part of any Taxes for
      which a full indemnity was paid by Lessee, such Indemnitee shall pay
      Lessee the amount of such refund, reduced by any Taxes imposed on such
      Indemnitee on receipt or accrual of such refund and increased by any Taxes
      saved by such Indemnitee by reason of the deductibility of such payment by
      such Indemnitee.  If, in addition to such refund, such Indemnitee receives
      an amount of interest on such refund, such Indemnitee shall pay to Lessee
      the portion of such interest which is fairly attributable to such refund,
      reduced by any Taxes imposed on such Indemnitee on receipt or accrual of
      such interest and increased by any Taxes saved by reason of the
      deductibility of such payment by such Indemnitee.  Such Indemnitee shall
      not be required to make any payment to Lessee pursuant to this Clause 5.12
      if, and for so long as, an Event of Default shall have occurred and be
      continuing.

(c)   Any Indemnitee in its sole discretion (by written notice to Lessee) may
      waive its rights to indemnification pursuant to Clause 5.7 with respect to
      any claim for any Tax and may refrain from contesting or continuing the
      contest of such claim, in which event Lessee shall have no obligation to
      indemnify such Indemnitee for the Taxes that are the subject of such
      claim.  If an Indemnitee agrees to a settlement of any contest conducted
      pursuant to this Clause 5.11 without the prior written consent of Lessee,
      which consent shall not be unreasonably withheld, then Lessor shall be
      deemed to have waived its rights to the indemnification provided for in
      Clause 5.7 with respect to the Tax liability accepted in such settlement.

5.13  Net Lease: This Agreement is a net lease.  Lessee's obligations under this
      Agreement are absolute and unconditional irrespective of any contingency
      whatsoever including (but not limited to):-

(a)   any right of set-off, counterclaim, recoupment, defense or other right
      which either party to this Agreement may have against the other;

(b)   any unavailability of the Aircraft for any reason, including, but not
      limited to, a requisition of the Aircraft or any prohibition or
      interruption of or interference with or other restriction against Lessee's
      use, operation or possession of the Aircraft;

(c)   any lack or invalidity of title or any other defect in title,
      airworthiness, merchantability, fitness for any purpose, condition,
      design, or operation of any kind or nature of the Aircraft for any
      particular use or trade, or for registration or documentation under the
      
                                      31
<PAGE>
 
      laws of any relevant jurisdiction, or any Event of Loss in respect of or
      any damage to the Aircraft;

(d)   any insolvency, bankruptcy, reorganization, arrangement, readjustment of
      debt, dissolution, liquidation or similar proceedings by or against Lessor
      or Lessee;

(e)   any invalidity or unenforceability or lack of due authorization of, or
      other defect in, this Agreement;

(f)   and Security Interests with respect to the Aircraft or Taxes; and/or

(g)   any other cause which but for this provision would or might otherwise have
      the effect of terminating or in any way affecting any obligation of Lessee
      under this Agreement.

5.14  Security

(a)   To the fullest extent permitted by Law and by way of continuing security
      Lessee as sole beneficial owner charges the Deposit and the Maintenance
      Reserves and all rights of Lessee to payment thereof and the debt
      represented thereby (the "Charged Monies") to Lessor by way of first fixed
      charge as security for Lessee's obligations and liabilities under this
      Agreement and the Other Agreements (the "Secured Liabilities").  Except as
      expressly permitted under this Agreement, Lessee will not be entitled to
      payment of the Charged Monies.  Lessee will not assign, transfer or
      otherwise dispose of all or part of its rights in the Charged Monies and
      it will enter into any additional documents and instruments necessary or
      advisable to evidence, create or perfect Lessor's rights to the Charged
      Monies;

(b)   If Lessee fails to comply with any provision of this Agreement or any
      Event of Default has occurred and is continuing, in addition to all rights
      and remedies accorded to Lessor elsewhere in this Agreement and under Law
      as a secured party in respect of the Charged Monies, Lessor may
      immediately or at any time thereafter, without prior notice to Lessee:-

      (i)   set-off all or any part of the Secured Liabilities against the
            liabilities of Lessor in respect of the Charged Monies;  or

      (ii)  apply or appropriate the Charged Monies in or towards the payment or
            discharge of the Secured Liabilities in such order as Lessor sees
            fit; and

(c)   If Lessor has exercised the set-off described in sub-clause (b) above,
      Lessee shall, following a demand in writing from Lessor, restore the
      Charged Monies to the level at which they stood immediately prior to such
      set-off.

 6.   MANUFACTURER'S WARRANTIES

6.1   Assignment: Notwithstanding this Agreement, Lessor will remain entitled to
      the benefit of each warranty, express or implied, with respect to the
      Aircraft, any Engine or Part so 

                                      32
<PAGE>
 
      far as concerns any manufacturer, vendor, subcontractor or supplier.
      Except to the extent Lessor otherwise directs, Lessor hereby authorizes
      Lessee to pursue any claim thereunder in relation to defects affecting the
      Aircraft, any Engine or Part and Lessee agrees diligently to pursue any
      such claim which arises at its own cost. Lessee will notify Lessor
      promptly upon becoming aware of any such claim.

6.2   Proceeds: Except to the extent Lessor otherwise agrees in a particular
      case, all proceeds of any such claim will be paid directly to Lessor but
      if and to the extent that such claim relates:-

(a)   to defects affecting the Aircraft which Lessee has rectified; or

(b)   to compensation for loss of use of the Aircraft, an Engine or any Part
      during the Term; and

      provided no Default has occurred and is continuing the proceeds will be
      paid to Lessee by Lessor but in the case of (a) above only on receipt of
      evidence satisfactory to Lessor that Lessee has rectified the relevant
      defect.

6.3   Parts: Except to the extent Lessor otherwise agrees in a particular case,
      Lessee will procure that all engines, components, furnishings or equipment
      provided by the manufacturer, vendor, subcontractor or supplier in
      replacement of a defective Engine or Part pursuant to the terms of any
      warranty will be installed promptly by Lessee and that title thereto free
      of Security Interests vests in Lessor.  On installation each part will be
      deemed to be a Part.  In the case of a Replacement Engine, Lessee will
      satisfy and perform each of the conditions and covenants set forth in
      Clause 11.1(c), and upon satisfaction of such conditions, such Replacement
      Engine will be deemed an "Engine" for all purposes of this Agreement.

6.4   Agreement: To the extent any warranties relating to the Aircraft are made
      available under an agreement between any manufacturer, vendor,
      subcontractor or supplier and Lessee, this Clause 6 is subject to that
      agreement.  However Lessee will:-

(a)   pay the proceeds of any claim thereunder to Lessor to be applied pursuant
      to Clause 6.2 and pending such payment will hold the claim and the
      proceeds on trust for Lessor; and

(b)   Lessee will take all such steps as are necessary at the end of the Term to
      ensure the benefit of any of those warranties which have not expired are
      vested in Lessor.

7.    LESSOR'S COVENANTS

7.1   Quiet Enjoyment: Lessor will not interfere with the quiet use, possession
      and enjoyment of the Aircraft by Lessee but the exercise by Lessor of its
      rights under or in connection with this Agreement will not constitute such
      an interference.  Lessor will procure at Lessee's request an undertaking
      of quiet enjoyment for the benefit of Lessee with respect to any
      prospective Lessor Lien.

8.5   Sub-Leasing and Wet-Leasing: LESSEE WILL NOT, WITHOUT THE PRIOR WRITTEN

             Agreement;

      and then in each case (A) with respect to a Part, only if it is
      reinstalled or replaced by a part complying with Clause 8.13(a) as soon as
      practicable and in any event no later than the Expiry Date, and (B) with
      respect to an Engine, title to such Engine shall remain vested in Lessor.

8.13  Installation of Engines and Parts: Lessee will:-

(a)   ensure that, except as permitted by this Agreement, no engine or part is
      installed on the Aircraft unless:-

      (i)    in the case of an engine, it is an engine of the same model as, or 
             an improved or advanced version of the Engine it replaces, which is
             in the same or better operating condition, has substantially
             similar hours available until the next scheduled checks,
             inspections, overhauls and shop visits and has the same or greater
             value and utility as the replaced Engine;

      (ii)   in the case of a part, it is in as good operating condition, has
             substantially similar hours available until the next scheduled
             checks, inspections, overhauls and shop visits, is of the same or a
             more advanced make and model and is of the same interchangeable
             modification status as the replaced Part;

      (iii)  in the case of a part, it has become and remains the property of
             Owner free from Security Interests and on installation on the

      Clause 8.13(a) if:-

      (i)    there is not available to Lessee at the time and in the place that 
             that engine or part is required to be installed on the Aircraft, a
             replacement engine or, as the case may be, part complying with the
             requirements of Clause 8.13(a);

      (ii)   it would result in an unreasonable disruption of the operation of
             the Aircraft and/or the business of Lessee to ground the Aircraft
             until an engine or part, as the case may be, complying with Clause
             8.13(a) becomes available for installation on the Aircraft; and

             complying with Clause 8.13(a).

8.14  Non-Installed Engines and Parts: Lessee will:-

(a)   ensure that any Engine or Part which is not installed on the Aircraft (or

      permitted by this Agreement, properly and safely stored, and kept free
      from Security Interests;

(b)   notify Lessor whenever any Engine is removed from the Aircraft and, from
      time to time, on request procure that any person to whom possession of an
      Engine is given acknowledges in writing to Lessor, in form and substance
      satisfactory to Lessor, that it will respect the interest of  Lessor in
      the Engine and will not seek to exercise any rights whatsoever in relation
      to it;

(c)   (notwithstanding the foregoing provisions of this sub-clause), be
      permitted, if no Default has occurred and is continuing, to install any
      Engine or Part on an aircraft, or in the case of a Part on an engine:-

      (i)    owned and operated by Lessee free from Security Interests;  or

      (ii)   leased or hired to Lessee pursuant to a lease or conditional sale
             agreement on a long-term basis and on terms whereby Lessee has full
             operational control of that aircraft or engine;  or

      (iii)  acquired by Lessee and/or financed or refinanced, and operated by
             Lessee, on terms that ownership of that aircraft or engine, as the
             case may be, pursuant to a lease or conditional sale agreement, or 
             a Security Interest therein, is vested in or held by any other 
             Person;

      provided that in the case of (ii) and (iii):-

                                      44
<PAGE>
 
      (1)   the terms of any such lease, conditional sale agreement or Security
            Interest will not have the effect of prejudicing the interest of
            Lessor in that Engine or Part;  and

      (2)   the lessor under such lease, the seller under such conditional sale
            agreement or the holder of such Security Interest, as the case may
            be, has confirmed and acknowledged in writing to Lessor, in form and
            substance satisfactory to Lessor, that it will respect the interest
            of Lessor in respect of that Engine or Part and that it will not
            seek to exercise any rights whatsoever in relation thereto.

8.15  Pooling of Engines and Parts:  Lessee will not enter into nor permit any
      pooling agreement or arrangement in respect of an Engine or Part without
      the prior written consent of Lessor.

8.16  Equipment Changes:

(a)   Lessee will not make any modification or addition to the Aircraft (each an
      "Equipment Change"), except for an Equipment Change which:-

      (i)   is expressly permitted by this Agreement, or

      (ii)  has the prior written approval of Lessor and which does not diminish
            the value, utility, condition, or airworthiness of the Aircraft;

(b)   So long as a Default has not occurred and is continuing, Lessee may
      remove any Equipment Change if it can be removed from the Aircraft without
      diminishing or impairing the value, utility, condition or airworthiness of
      the Aircraft; and

(c)   Lessee shall indemnify Lessor on an After-Tax Basis for any and all Taxes
      payable by Lessor as the case may be, as a result of an Equipment Change.

8.17  Title on an Equipment Change:

(a)   Title to all Parts installed on the Aircraft whether by way of
      replacement, as the result of an Equipment Change or otherwise (except
      those installed pursuant to Clause 8.13(b)) will on installation, without
      further act, vest in Lessor subject to this Agreement free and clear of
      all Security Interests. Lessee will at its own expense take all such steps
      and execute, and procure the execution of, all such instruments as Lessor
      may require and which are necessary to ensure that title so passes  to
      Lessor according to all applicable Laws.  At any time when requested by
      Lessor, Lessee will provide evidence to Lessor's satisfaction (including
      the provision, if required, to Lessor of one or more legal opinions) that
      title has so passed to Lessor;

(b)   Lessor may require Lessee to remove any Equipment Change and to restore
      the Aircraft to its condition prior to that Equipment Change; and

                                      45
<PAGE>
 
(c)   Except as referred to in Clause 8.17(b) any Engine or Part at any time
      removed from the Aircraft will remain the property of Lessor until a
      replacement has been made in accordance with this Agreement and until
      title in that replacement has passed, according to applicable Laws, to
      Lessor subject to this Agreement and free of all Security Interests.  Upon
      title to such replacement so passing to Lessor, title to the replaced
      Engine or Part, will, provided no Default has occurred and is continuing,
      pass to Lessee.

8.18  Third Party: Lessee will procure that no person (other than Lessor) will
      act in any manner inconsistent with its obligations under this Agreement
      and that all persons will comply with those obligations as if references
      to "Lessee" included a separate reference to those persons.

9.    INSURANCE

9.1   Insurances: Lessee will maintain in full force during the Term, and
      thereafter as expressly required in this Agreement, insurances in respect
      of the Aircraft in form and substance satisfactory to Lessor (the
      "Insurances" which expression includes, where the context so admits, any
      relevant re-insurance(s)) through such brokers and with such insurers and
      having such deductibles and being subject to such exclusions as may be
      approved by Lessor from time to time. The Insurances will be effected
      either:-

(a)   on a direct basis with insurers of recognized standing who normally
      participate in aviation insurances in the leading international insurance
      markets and led by reputable underwriter(s) approved by Lessor; or

(b)   with a single insurer or group of insurers approved by Lessor who does not
      retain the risk but effects substantial reinsurance with reinsurers in the
      leading international insurance markets and through brokers each of
      recognized standing and acceptable to Lessor for a percentage acceptable
      to Lessor of all risks insured (the "Reinsurances").

9.2   Requirements: Lessor's current requirements as to required Insurances are
      as specified in this Clause and in Schedule 4. Lessor may from time to
      time stipulate other requirements for the Insurances so that the scope and
      level of cover is maintained in line with best industry practice and the
      interests of Lessor protected.

9.3   Change: If at any time Lessor wishes to revoke its approval of any 
      insurer, reinsurer, insurance or reinsurance, Lessor and/or its brokers
      will consult with Lessee and Lessee's brokers (as for the time being
      approved by Lessor) regarding whether that approval should be revoked to
      protect the interests of the parties insured. If, following the
      consultation, Lessor considers that any change should be made, Lessee will
      then arrange or procure the arrangement of alternative cover satisfactory
      to Lessor.

9.4   Insurance Covenants: Lessee will:-

(a)   ensure that all legal requirements as to insurance of the Aircraft, any
      Engine or any Part which may from time to time be imposed by the laws of
      the State of Registration or any state to, from or over which the Aircraft
      may be flown, in so far as they affect or concern 

                                      46
<PAGE>
 
      the operation of the Aircraft, are complied with and in particular those
      requirements compliance with which is necessary to ensure that (i) the
      Aircraft is not in danger of detention or forfeiture, (ii) the Insurances
      remain valid and in full force and effect, and (iii) the interests of the
      Indemnitees in the Insurances and the Aircraft or any Part are not thereby
      prejudiced;

(b)   not use, cause or permit the Aircraft, any Engine or any Part to be used
      for any purpose or in any manner not covered by the Insurances or outside
      any geographical limit imposed by the Insurances;

(c)   comply with the terms and conditions of each policy of the Insurances and
      not do, consent or agree to any act or omission which:-

      (i)    invalidates or may invalidate the Insurances; or

      (ii)   renders or may render void or voidable the whole or any part of any
             of the Insurances; or

      (iii)  brings any particular liability within the scope of an exclusion or
             exception to the Insurances;

(d)   not take out without the prior written approval of Lessor any
      insurance or reinsurance in respect of the Aircraft other than those
      required under this Agreement unless relating solely to hull total
      loss, business interruption, profit commission and deductible risk;

(e)   commence renewal procedures at least 30 days prior to expiry of any of the
      Insurances and provide to Lessor:-

      (i)    if requested by Lessor, a written status report of renewal 
             negotiation 14 days prior to each expiry date;

      (ii)   telexed telecopy confirmation of completion of renewal prior to 
             each expiry date; and

      (iii)  certificates of insurance (and where appropriate certificates of
             reinsurance), and broker's (and any reinsurance brokers') letter of
             undertaking in a form acceptable to Lessor in English, detailing
             the coverage and confirming the insurers' (and any reinsurers')
             agreement to the specified insurance requirements of this Agreement
             within 7 days after each renewal date;

(f)   on request, provide to Lessor copies of documents or other information 
      evidencing the Insurances;

(g)   on request, provide to Lessor evidence that the Insurance premiums have
      been paid;

(h)   not make any modification or alteration to the Insurances material and
      adverse to the interests of any of the Indemnitees;

                                      47
<PAGE>
 
(i)   be responsible for any deductible under the Insurances; and

(j)   provide any other insurance and reinsurance related information, or
      assistance, in respect of the Insurances as Lessor may reasonably require.

9.5   Failure to Insure: If Lessee fails to maintain the Insurances in 
      compliance with this Agreement, each of the Indemnitees will be entitled
      but not bound, (without prejudice to any other rights of Lessor under this
      Agreement):-

(a)   to pay the premiums due or to effect and maintain insurances satisfactory
      to it or otherwise remedy Lessee's failure in such manner (including,
      without limitation to effect and maintain an "owner's interest" policy) as
      it considers appropriate. Any sums so expended by it will become
      immediately due and payable by Lessee to Lessor on an After-Tax Basis
      together with interest thereon at the rate specified in Clause 5.11, from
      the date of expenditure by it up to the date of reimbursement by Lessee;
      and

(b)   at any time while such failure is continuing to require the Aircraft to
      remain at any airport or to proceed to and remain at any airport
      designated by it until the failure is remedied to its satisfaction.

9.6   Continuing Indemnity: Lessee shall effect and maintain insurance after the
      Expiry Date with respect to its liability under the Indemnity in Clause 10
      for 2 years which provides for each Indemnitee to be named as additional
      insured.  Lessee's obligation in this Clause shall not be affected by
      Lessee ceasing to be lessee of the Aircraft and/or any of the Indemnitees
      ceasing to have any interest in respect of the Aircraft.

9.7   Application of Insurance Proceeds:-

      As between Lessor and Lessee:-

(a)   all insurance payments received as the result of an Event of Loss or
      Engine Event of Loss occurring during the Term will be paid to Lessor and
      Lessor will pay the balance of those amounts to Lessee after deduction of
      all amounts which may be or become payable by Lessee to Lessor under this
      Agreement (including under Clause 11.1(b));

(b)   all insurance proceeds of any property, damage or loss to the Aircraft,
      any Engine or any Part occurring during the Term not constituting an Event
      of Loss or Engine Event of Loss and in excess of the Damage Notification
      Threshold will be applied in payment (or to reimburse Lessee) for repairs
      or replacement property upon Lessor being satisfied that the repairs or
      replacement have been effected in accordance with this Agreement.
      Insurance proceeds in amounts below the Damage Notification Threshold may
      be paid by the insurer directly to Lessee. Any balance remaining may be
      retained by Lessor;

(c)   all insurance proceeds in respect of third party liability will, except to
      the extent paid by the insurers to the relevant third party, be paid to
      Lessor to be paid directly in satisfaction of the relevant liability or to
      Lessee in reimbursement of any payment so made; and

                                      48
<PAGE>
 
(d)   notwithstanding Clauses 9.7(a), (b) or (c), if at the time of the payment
      of any such insurance proceeds a Default has occurred and is continuing,
      all such proceeds will be paid to or retained by Lessor to be applied
      toward payment of any amounts which may be or become payable by Lessee in
      such order as Lessor sees fit or as Lessor may elect.

      To the extent insurance proceeds are paid to Lessee, Lessee agrees to
      comply with the foregoing provisions and apply or pay over such proceeds
      as so required.

10.   INDEMNITY

10.1  GENERAL:  LESSEE AGREES TO DEFEND, INDEMNIFY AND HOLD HARMLESS THE
      INDEMNITEES ON AN AFTER-TAX BASIS FROM AND AGAINST ANY AND ALL CLAIMS,

      (B)   WHICH ARISE OUT OF ANY ACT OR OMISSION WHICH INVALIDATES OR WHICH
            RENDERS VOIDABLE ANY OF THE INSURANCES; AND

      (C)   WHICH MAY AT ANY TIME BE SUFFERED OR INCURRED AS A CONSEQUENCE OF
            ANY DESIGN, ARTICLE OR MATERIAL IN THE AIRCRAFT, ANY ENGINE OR ANY
            PART OR ITS OPERATION OR USE CONSTITUTING AN INFRINGEMENT OF PATENT,
            COPYRIGHT, TRADEMARK, DESIGN OR OTHER PROPRIETARY RIGHT OR A BREACH

      EXTENT IT ARISES SOLELY AS A RESULT OF THE GROSS NEGLIGENCE OR WILLFUL
      MISCONDUCT OF THAT INDEMNITEE, LESSOR TAXES OR A LESSOR LIEN.

10.2  Duration: The indemnities contained in this agreement will continue in 
      full force following the end of the Term notwithstanding any breach or
      repudiation by Lessor or Lessee of this Agreement or any termination of
      the lease of the Aircraft hereunder.

11.   EVENTS OF LOSS

11.1

(a)   Pre-delivery: If an Event of Loss occurs prior to delivery of the
      Aircraft to Lessee, Lessor will have the option, exercisable by giving
      Lessee notice in writing, to substitute an alternative aircraft of the
      same manufacture, model, value and utility as the Aircraft. If Lessor
      exercises such option, Lessee shall be obliged to lease such substitute
      aircraft pursuant to the terms and conditions of this Agreement and such
      substitute aircraft shall constitute the Aircraft for all purposes of this
      Agreement. Lessor shall provide Lessee with details of the substitute
      aircraft as soon as may be practicable after the occurrence of the Event
      of Loss. If Lessor advises Lessee that Lessor does not wish to exercise
      such option, this Agreement will immediately terminate and except as
      expressly stated in this Agreement neither party will have any further
      obligation or liability under this Agreement other than pursuant to Clause
      16.9 except that Lessor will return the Deposit to Lessee; and

(b)   Post-delivery: If an Event of Loss occurs after delivery of the Aircraft
      to Lessee, Lessee will pay the Agreed Value to Lessor on or prior to the
      earlier of (i) 5 Business Days after the Event of Loss and (ii) the date
      of receipt of insurance proceeds in respect of that Event of Loss. Subject
      to the rights of any insurers and reinsurers or other third party, upon
      irrevocable payment in full to Lessor of that amount and all other amounts
      which may be or become payable to Lessor under this Agreement, Lessor will
      without recourse or warranty (except as to Lessor's Liens) and without
      further act, be deemed to have transferred to Lessee all of Lessor's
      rights to any Engines and Parts not installed when the Event of Loss
      occurred, all on an as-is where-is basis, and will at Lessee's expense,
      execute and deliver such bills of sale and other documents and instruments
      as Lessee may reasonably request to evidence (on the public record or
      otherwise) the transfer and the vesting of Lessor's rights in such Engines
      and Parts in Lessee, free and clear of all rights of Lessor and Lessor
      Liens.

(c)   Engine Event of Loss: From the Delivery Date upon an Engine Event of Loss,
      Lessee shall give Lessor prompt written notice thereof and shall, within
      45 days after such occurrence, convey to Lessor, as replacement for the
      Engine suffering such event, title to a Replacement Engine.  Each
      Replacement Engine shall be free of all Security Interests and shall be in
      as good an operating condition as the Engine being replaced, assuming the
      Engine being replaced was in the condition and repair required by the
      terms hereof immediately prior to the Engine Event of Loss. Upon full
      compliance by Lessee with the 

                                      50
<PAGE>
 
      terms of this Clause 11.1(c), Lessor will transfer to Lessee title to the
      Engine which suffered the Engine Event of Loss. Prior to or at the time of
      any such conveyance, Lessee, at its own expense, will promptly (i) furnish
      Lessor with a full warranty bill of sale, in form and substance reasonably
      satisfactory to Lessor, with respect to such Replacement Engine; 
      (ii) cause a lease supplement (in form and substance satisfactory to
      Lessor) subjecting such Replacement Engine to this Agreement, to be duly
      executed by Lessee, and recorded pursuant to applicable Law; (iii) furnish
      Lessor with such evidence of title to such Replacement Engine as Lessor
      may reasonably request; (iv) furnish Lessor with an opinion of Lessee's
      counsel to the effect that title to such Replacement Engine has been duly
      conveyed to Lessor subject to this Agreement, free and clear of all
      Security Interests, and that such Replacement Engine is duly leased
      hereunder; (v) furnish a certificate signed by a duly authorized financial
      officer or executive of Lessee certifying that, upon consummation of such
      replacement, no Event of Default will have occurred or be continuing; 
      (vi) furnish Lessor with such documents as Lessor may reasonably request
      in connection with the consummation of the transactions contemplated by
      this Clause 11.1(c), in each case in form and substance satisfactory to
      Lessor; and (vii) furnish such Financing Statements incorporating the
      Replacement Engine as may be requested by Lessor. For all purposes hereof,
      each such Replacement Engine shall be deemed part of the property leased
      hereunder, shall be deemed an "Engine" as defined herein and shall be
      deemed part of the same Aircraft as was the Engine replaced thereof. No
      Engine Event of Loss covered by this Clause 11.1(c) shall result in any
      reduction in Rent or affect Lessee's obligation to pay Engine Maintenance
      Reserves or the amount thereof to be paid by Lessee.

      Lessee shall indemnify each Indemnitee on an After-Tax Basis for any
      adverse tax consequence to such Indemnitee of the replacement of one or
      more Engines pursuant to this Clause 11.1.

11.2  Substitute Aircraft:

(a)   Without prejudice to the provisions of Clause 11.1 (b), if an Event of
      Loss occurs after delivery of the Aircraft to Lessee, Lessor will have the
      option, exercisable by giving Lessee notice in writing, to substitute an
      alternative aircraft (the "Substitute Aircraft") of the same manufacture
      and model as the Aircraft and having a value, utility and condition equal
      to or greater than the Aircraft as at the date of occurrence of the Event
      of Loss which Substitute Aircraft will be leased by Lessor to Lessee for
      the remainder of the Term pursuant to the terms and conditions of this
      Agreement.  If Lessor exercises such option, the Substitute Aircraft will
      constitute the Aircraft for all purposes of this Agreement in respect of
      facts and circumstances arising after the date of delivery thereof to
      Lessee.  Lessor shall provide Lessee with details of the Substitute
      Aircraft as soon as may be practicable after the occurrence of the Event
      of Loss;

(b)   Lessor will use all reasonable endeavors to deliver the Substitute
      Aircraft to Lessee as soon as may be practicable following the date of
      occurrence of the Event of Loss but not later than 3 months after such
      date; and

                                      51
<PAGE>
 
(c)   Lessee agrees to enter into such documentation as Lessor may require in
      order to reflect the leasing of the Substitute Aircraft as aforesaid
      including, without limitation, documentation in respect of the Insurances.

      Lessee shall indemnify each Indemnitee on an After-Tax Basis for any
      adverse tax consequence to such Indemnitee of the replacement of the
      Aircraft or Airframe pursuant to this Clause 11.2.

11.3  Requisition: During any requisition for use or hire of the Aircraft, any
      Engine or Part which does not constitute an Event of Loss:-

(a)   the Rent and other charges payable under this Agreement will not be
      suspended or abated either in whole or in part, and Lessee will not be
      released from any of its other obligations under the Agreement (other than
      operational obligations with which Lessee is unable to comply solely by
      virtue of the requisition); and

(b)   so long as no Default has occurred and is continuing, Lessee will be
      entitled to any hire paid by the requisitioning authority in respect of
      the Term. Lessee will, as soon as practicable after the end of any such
      requisition, cause the Aircraft to be put into the condition required by
      this Agreement. Lessor will be entitled to all compensation payable by the
      requisitioning authority in respect of any change in the structure, state
      or condition of the Aircraft arising during the period of requisition, and
      Lessor will apply such compensation in reimbursing Lessee for the cost of
      complying with its obligations under this Agreement in respect of any such
      change, but so that, if any Default has occurred and is continuing, Lessor
      may apply the compensation or hire in or towards settlement of any amounts
      owing by Lessee under this Agreement.

12.   RETURN OF AIRCRAFT

12.1  Return: On the Expiry Date or redelivery of the Aircraft pursuant to 
      Clause 13.2 or termination of the leasing of the Aircraft under this
      Agreement Lessee will, unless an Event of Loss has occurred, at its
      expense, redeliver the Aircraft and Aircraft Documents to Lessor at the
      Redelivery Location or such other airport as is mutually acceptable to the
      parties hereto, in accordance with the procedures and in compliance with
      the conditions set forth in Schedule 3, free and clear of all Security
      Interests and Permitted Liens (other than Lessor Liens) and in a condition
      qualifying for immediate certification of airworthiness by the FAA or as
      otherwise agreed by Lessor and Lessee.

12.2  Final Inspection: Immediately prior to redelivery of the Aircraft, Lessee
      will make the Aircraft available to Lessor for inspection ("Final
      Inspection") in order to verify that the condition of the Aircraft
      complies with this Agreement. The Final Inspection will be long enough to
      permit Lessor to:-

(a)   inspect the Aircraft Documents and uninstalled Parts;

(b)   inspect the Aircraft, provided that such inspection will not interfere
      with the scheduled operation of the Aircraft;

                                      52
<PAGE>
 
(c)   inspect the Engines, including without limitation (i) a borescope
      inspection of (A) the low pressure and high pressure compressors and 
      (B) turbine and combustion areas, (ii) engine condition runs and 
      (iii) review of Engine trend monitoring data and technical log reports
      covering the last ninety (90) days of operation; and

(d)   perform a complete borescope inspection of the APU; and

(e)   observe a 2 hour demonstration flight (with Lessor's representatives as
      on-board observers).

12.3  Non-Compliance: To the extent that, at the time of Final Inspection, the
      condition of the Aircraft does not comply with this Agreement, Lessee will
      at Lessor's option:-

(a)   immediately rectify the non-compliance and to the extent the non-
      compliance extends beyond the Expiry Date, the Term will be automatically
      extended and this Agreement will remain in force until the non-compliance
      has been rectified; or

(b)   redeliver the Aircraft to Lessor and indemnify Lessor on an After-Tax
      Basis, and provide to Lessor's satisfaction cash as security for that
      indemnity, against the cost of putting the Aircraft into the condition
      required by this Agreement.

12.4  Redelivery: Upon redelivery Lessee will provide to Lessor, upon Lessor's
      request, all documents necessary to export the Aircraft from the Habitual
      Base (including, without limitation, a valid and subsisting export license
      for the Aircraft) and required in relation to the deregistration of the
      Aircraft with the Air Authority.

12.5  Acknowledgment: Provided Lessee has complied with its obligations under
      this Agreement, following redelivery of the Aircraft by Lessee to Lessor
      at the Redelivery Location, Lessor will deliver to Lessee an
      acknowledgment confirming that Lessee has redelivered the Aircraft to
      Lessor in accordance with this Agreement.

12.6  Maintenance Program:

(a)   Prior to the Expiry Date and upon Lessor's request, Lessee will provide
      Lessor or its agent reasonable access to the Agreed Maintenance Program
      and the Aircraft Documents in order to facilitate the Aircraft's
      integration into any subsequent operator's fleet; and

(b)   Lessee will, if requested by Lessor to do so, upon return of the Aircraft
      deliver to Lessor a certified true current and complete copy of the Agreed
      Maintenance Program. Lessor agrees that it will not disclose the contents
      of the Agreed Maintenance Program to any person or entity except to the
      extent necessary to monitor Lessee's compliance with this Agreement and/or
      to bridge the maintenance program for the Aircraft from the Agreed
      Maintenance Program to another program after the Expiry Date.

                                      53

12.7  Fuel: Upon redelivery of the Aircraft to Lessor, an adjustment will be 
      made in respect of fuel on board on the Delivery Date and the Expiry Date
      at the price then prevailing at the Redelivery Location.

12.8  Automatic Extension of Term:  In the event of Lessee's failure to make the
      Aircraft available to Lessor for timely inspection pursuant to Clauses
      12.2 hereof, non-compliance of the condition of the Aircraft under Clause
      12.3 hereof or any other failure of Lessee which prevents timely
      Redelivery of the Aircraft to Lessor, the Term of this Agreement will be
      automatically extended and this Agreement will remain in force until such
      non-compliance has been rectified, with Lessee being obligated to pay Rent
      at a rate specified in Clause 5.3 plus 50 percent on a per diem basis with
      respect to the period of such extension.

      by operation of law or pursuant to or in compliance with any judgment,
      decree or order of any court or any order, rule or regulation of any
      Government Entity).  Lessee acknowledges that the occurrence of any Event

      or any of the Operative Documents and, if such failure is in the
      reasonable opinion of Lessor capable of remedy, the failure continues for

(d)   Representation: any representation or warranty made (or deemed to be
      repeated) by Lessee in or pursuant to this Agreement or in any document or
      certificate or statement is or proves to have been incorrect in any
      material respect when made or deemed to be repeated; or

(e)   Cross Default:

     (i)    a final judgment for the payment of money not covered by insurance
            in excess of Two Hundred Fifty Thousand Dollars ($250,000), or final

            adequately bonded; or

      (ii)  attachments or other Security Interests shall be issued or entered
            against substantially all of the property of Lessee and shall remain

            Interests created in connection with monies borrowed or obligations
            agreed to by Lessee in the ordinary course of its business; or

      (iii) Lessee shall default in the payment of any sum which by itself is
            in excess of $100,000 or any sums which in aggregate exceed $250,000
            notwithstanding that any particular individual sum thereof does not
            exceed $100,000 of any one or more obligations for the payment of
            borrowed money, for the deferred purchase price of property or for
            the payment of rent or hire under any lease of aircraft when the
            same becomes due if such nonpayment results in or would permit an
            acceleration of such indebtedness, or Lessee shall default in the
            performance of any other term, agreement, or condition contained in
            any agreement or instrument under or by which any such obligation is
            created, evidenced or secured, if the effect of such default is to
            cause or permit such obligation to become due prior to its stated
            maturity; or

      (iv)  any event of default or termination event, howsoever described,

      (ii)  at Lessor's election, either one of the amounts determined pursuant
            to Clause 13.2(e) or Clause 13.2(f) below or any lost profits
            suffered by Lessor as a consequence of Lessor's inability to place
            the Aircraft with another lessee on financial terms that are as
            favorable to Lessor as the terms of this Agreement;

      (iii) all costs associated with Lessor's exercise of its remedies
            hereunder, including, but not limited to, repossession costs, legal
            fees, Aircraft storage costs, Aircraft re-lease or sale costs and
            Lessor's internal costs and expenses (including the cost of
            personnel time calculated based upon the compensation paid to the
            individuals involved on an annual basis and a general Lessor
            overhead allocation);

      (iv)  any loss, premium, penalty or expense which may be incurred in
            repaying funds raised to finance the Aircraft or in unwinding any
            financial instrument relating in whole or in part to Lessor's
            financing of the Aircraft;

      (v)   any loss, cost, expense or liability sustained by Lessor due to
            Lessee's failure to redeliver the Aircraft in the condition required
            by this Agreement; and

      (vi)  any other losses (including lost profits), damage, expense, cost or
            liability which Lessor suffers or incurs as a result of the Event of
            Default and/or termination of this Agreement, including an amount
            sufficient to fully compensate Lessor for any loss of or damage to
            Lessors residual interest in the Aircraft caused by Lessee's
            default; and/or

(d)  either: -

     (i)    enter upon the premises where all or any part of the Aircraft is 
            located and take immediate possession of and, at Lessor's sole
            option, remove the same (and/or any engine which is not an Engine
            but which is installed on the Airframe, subject to the rights of the
            owner, lessor or secured party thereof) or cause it to be
            redelivered to Lessor at a location in the United States identified
            by Lessor (or such other location as Lessor may require) (the
            "Return Location"), by summary proceedings or otherwise, all without
            liability accruing to Lessor for or by reason of such entry or
            taking of possession whether for the restoration of damage to
            property, or otherwise, caused by such entry or taking, except
            damages caused by gross negligence or willful misconduct; and Lessor
            is hereby irrevocably, by way of security for Lessee's obligations
            under this Agreement, appointed attorney for Lessee in causing the
            redelivery or in directing the pilots of Lessee or other pilots to
            fly the Aircraft to that airport and will have all the powers and
            authorizations necessary for taking that action; or

      (ii)  by serving notice require Lessee to redeliver the Aircraft to Lessor
            at a point within the continental United States designated by
            Lessor; and/or

                                      58
<PAGE>
 
(e)   sell at private or public sale, as Lessor may determine, or hold, use, 
      operate or lease to others the Aircraft as Lessor in its sole discretion 
      may determine, all free and clear of any rights of Lessee; and/or

(f)   whether or not Lessor shall have exercised, or shall thereafter at any
      time exercise, any of its rights under paragraph (a), paragraph (b),
      paragraph (c), paragraph (d), or paragraph (e) of this Clause 13.2,
      Lessor, by 30 days written notice to Lessee specifying a payment date, may
      demand that Lessee pay to Lessor, and Lessee shall pay to Lessor, on the
      payment date specified in such notice, as liquidated damages for loss of
      bargain and not as a penalty (in lieu of the Rent due for the period
      commencing after the date specified for payment in such notice), any
      unpaid Rent for the Aircraft and other amounts owing under this Agreement
      (prorated in the case of Rent on a daily basis) to and including the
      payment date specified in such notice, plus the amount, if any, by which
      the aggregate Rent for the remainder of the Term (determined without
      reference to any right of Lessor to terminate the leasing of the Aircraft,
      whether or not such right is exercised), discounted periodically (equal to
      installment frequency) to present worth at the interest rate of 4 percent
      (4%) per annum, exceeds the fair market rental value (determined pursuant
      to the Appraisal Procedure) of the Aircraft for the remainder of the Term,
      after discounting such fair market rental value periodically (equal to
      installment frequency) to present worth as of the payment date specified
      in such notice at the interest rate of 4 percent (4%) per annum; and/or

(g)   In the event that Lessor, pursuant to Clause 13.2(e) above, shall have
      relet the Aircraft under a lease which extends at least to the date upon
      which the Term for the Aircraft would have expired but for Lessee's
      default, Lessor, in lieu of exercising its rights under Clause 13.2(f)
      above with respect to the Aircraft, may, if it shall so elect, demand that
      Lessee pay Lessor, and Lessee shall pay Lessor, as liquidated damages for
      loss of bargain and not as a penalty (in lieu of the Rent for the Aircraft
      due after the time of reletting) any unpaid Rent for the Aircraft due up
      to the date of reletting and any other amounts owing under this Agreement,
      plus the amount, if any, by which the aggregate Rent for the Aircraft,
      which would otherwise have become due over the remainder of the Term
      (determined without reference to any right of Lessor to terminate the
      leasing of the Aircraft, whether or not such right is exercised),
      discounted periodically (equal to installment frequency) to present worth
      as of the date of reletting at the interest rate of 4 percent (4%) per
      annum, exceeds the aggregate basic rental payments to become due under the
      reletting from the date of such reletting to the date upon which the Term
      for the Aircraft would have expired but for Lessee's default, discounted
      periodically (equal to installment frequency) to present worth as of the
      date of the reletting at the interest rate of 4 percent (4%) per annum;
      and/or

(h)   in lieu of the remedies set forth in paragraphs (a), (c), (d), (e), (f),
      and (g) of this Clause 13.2, by 30 days written notice to Lessee
      specifying a payment date, Lessor may demand that Lessee pay to Lessor,
      and Lessee shall pay to Lessor on the payment date specified in such
      notice as liquidated damages for loss of bargain and not as a penalty (in
      lieu of the Rent due for the period commencing after the date specified
      for payment in such notice), any unpaid Rent for the Aircraft and other
      amounts payable under this 

                                      59
<PAGE>
 
      Agreement (prorated in the case of Rent on a daily basis) to and including
      the payment date specified in such notice, plus an amount equaling the
      aggregate Rent for the remainder of the Term, discounted periodically
      (equal to installment frequency) to present worth at the interest rate of
      4 per cent (4%) per annum;

(i)   draw upon the Deposits or the Maintenance Reserves furnished under this
      Agreement or the Other Agreements and apply such amounts to amounts owing
      to Lessor hereunder.

      Lessee, for itself and for its successors and assigns, hereby agrees that,
      to the extent now or hereafter permitted by applicable Law,
      notwithstanding any provision of the Federal Bankruptcy Code as amended
      from time to time, the title of Lessor to the Aircraft and any right of
      Lessor to take possession of the Aircraft in compliance with the
      provisions of this Agreement, in each case, upon the occurrence and
      continuance of an Event of Default, shall not be affected by the
      provisions of the Federal Bankruptcy Code, as amended from time to time.

      In addition to the foregoing, Lessee shall be liable for any and all
      unpaid Rent and other amounts payable under this Agreement during or after
      the exercise of any of the aforementioned remedies, together with interest
      on such unpaid amounts at the Interest Rate set forth in Letter Agreement
      No. 1, and until satisfaction of all of Lessee's obligations to Lessor
      hereunder and (on an After-Tax Basis) for all reasonable legal fees and
      other reasonable costs and expenses incurred by Lessor by reason of the
      occurrence of any Event of Default or the exercise of Lessor's remedies
      with respect thereto, including all costs and expenses incurred in
      connection with the return of the Aircraft in accordance with the terms of
      Clause 12 hereof or in placing the Aircraft in the condition and with
      airworthiness certification as required by such Clause.

      In effecting any repossession, Lessor and its representatives and agents,
      to the extent permitted by Law, shall: (i) have the right to enter upon
      any premises where it reasonably believes the Aircraft, the Airframe, an
      Engine or Part to be located; (ii) not be liable, in conversion or
      otherwise, for the taking of any personal property of Lessee which is in
      or attached to the Aircraft, the Airframe, an Engine or Part which is
      repossessed; provided, however, that Lessor shall return to Lessee all
      personal property of Lessee or its passengers which was on the Aircraft at
      the time Lessor re-takes possession of the Aircraft; (iii) not be liable
      or responsible, in any manner, for any inadvertent damage or injury to any
      of Lessee's property in repossessing and holding the Aircraft, the
      Airframe, an Engine or Part, except for that caused by or in connection
      with Lessor's gross negligence or willful acts; (iv) have the right to
      maintain possession of and dispose of the Aircraft, the Airframe, an
      Engine or Part on any premises owned by Lessee or under Lessee's control;
      and (v) have the right to obtain a key to any premises at which the
      Aircraft, the Airframe, an Engine or Part may be located from the landlord
      or owner thereof.

      If reasonably required by Lessor, Lessee, at its sole expense, shall
      assemble and make the Aircraft, the Airframe, an Engine or Part available
      at a place designated by Lessor in accordance with Clause 12 hereof.
      Lessee hereby agrees that, in the event of the return 

<PAGE>
 
      to or repossession by Lessor of the Aircraft, the Airframe, an Engine or
      Part, any rights in any warranty (express or implied) previously assigned
      to Lessee or otherwise held by Lessee shall without further act, notice or
      writing be assigned or reassigned to Lessor, if assignable. Lessee shall
      be liable to Lessor on an After-Tax Basis for all reasonable expenses,
      disbursements, costs and fees incurred in (i) repossessing, storing,
      preserving, shipping, maintaining, repairing and refurbishing the
      Aircraft, the Airframe, an Engine or Part to the condition required by
      Clause 12 hereof and (ii) preparing the Aircraft, the Airframe, an Engine
      or Part for sale or lease, advertising the sale or lease of the Aircraft,
      the Airframe, an Engine or Part and selling or releasing the Aircraft, the
      Airframe, an Engine or Part. Lessor is hereby authorized and instructed,
      at its option, to make reasonable expenditures which Lessor considers
      advisable to repair and restore the Aircraft, the Airframe, an Engine or
      Part to the condition required by Clause 12 hereof, all at Lessee's sole
      expense.

      At any public sale of the Aircraft, the Airframe, an Engine or Part
      pursuant to this Clause, Lessor may bid for and purchase such property and
      Lessee agrees that the amounts paid therefor shall be used in the
      computation contemplated herein.

      With the exception that the remedy in Clause 13.2(g) can be elected only
      if the remedy in Clause 13.2(f) is not elected and the remedy in Clause
      13.2(h) can be elected only in lieu of all other remedies save the
      remedies in Clauses 13.2(b) and 13.2(i), no remedy referred to in this
      Clause 13 is intended to be exclusive, but, to the extent permissible
      hereunder or under applicable Law, each shall be cumulative and in
      addition to any other remedy referred to above or otherwise available to
      Lessor at Law or in equity; and the exercise or beginning of exercise by
      Lessor of any one or more of such remedies shall not preclude the
      simultaneous or later exercise by Lessor of any or all of such other
      remedies; provided, however, that nothing in this Clause 13 shall be
      construed to permit Lessor to obtain a duplicate recovery of any element
      of damages to which Lessor is entitled.  No express or implied waiver by
      Lessor of any Default or Event of Default shall in any way be, or be
      construed to be, a waiver of any future or subsequent Default.

13.3  Deregistration: If an Event of Default occurs, Lessor may sell or 
      otherwise deal with the Aircraft free and clear of any leasehold or other
      interest of Lessee as if this Agreement had never been made and Lessee
      will at the request of Lessor take all steps necessary to effect (if
      applicable) deregistration of the Aircraft and its export from the country
      where the Aircraft is for the time being situated and any other steps
      necessary to enable the Aircraft to be redelivered to Lessor in accordance
      with this Agreement including without limitation execution and filing of a
      certificate or other instrument of lease termination with the Air
      Authority and; Lessee hereby irrevocably and by way of security for its
      obligations under this Agreement appoints (which appointment is coupled
      with an interest) Lessor as its attorney to execute and deliver any
      documentation and to do any act or thing required in connection with the
      foregoing.

14.   ASSIGNMENT

14.1  Lessee's Assignment: LESSEE WILL NOT ASSIGN, TRANSFER (VOLUNTARILY OR
      INVOLUNTARILY BY OPERATION OF LAW OR OTHERWISE) OR CREATE OR PERMIT TO
      EXIST ANY SECURITY INTEREST OVER, ANY OF ITS RIGHTS UNDER THIS AGREEMENT.

14.2  Lessor's Assignment: Lessor may assign or transfer all or any of its
      rights under this Agreement and in the Aircraft.  In the case of an
      assignment other than by way of security, Lessor will be released from and
      will have no further obligation under this Agreement following the
      assignment of all its rights under this Agreement and the assumption by
      the assignee or transferee of all of Lessor's obligations under this
      Agreement.  Notwithstanding any such assignment, Lessor will remain
      entitled to the benefit of each indemnity and the liability insurances
      effected under this Agreement. Lessee will comply with all reasonable
      requests of Lessor, its successors and assigns in respect of any such
      assignment. Lessor will promptly notify Lessee of any assignment.

14.3  Transfer: If Lessor desires to effect any assignment or transfer of its
      rights and obligations under this Agreement, Lessee agrees to cooperate
      and take all such steps as Lessor may reasonably request to give the
      transferee the benefit of this Agreement and to acknowledge the release of
      Lessor from its obligations hereunder as of the time of such assignment or
      transfer.

15.   ILLEGALITY

      If it is or becomes unlawful in any jurisdiction for Lessor to give effect
      to any of its obligations as contemplated by this Agreement or to continue
      this Agreement, Lessor may by notice in writing to Lessee terminate the
      leasing of the Aircraft under this Agreement and Lessee will forthwith
      redeliver the Aircraft to Lessor in accordance with Clause 12. Without
      prejudice to the foregoing Lessor will consult in good faith with Lessee
      as to any steps which may be taken to restructure the transaction to avoid
      that unlawfulness but will be under no obligation to take any such steps.

16.   MISCELLANEOUS

16.1  Waivers, Remedies Cumulative: The rights of Lessor under this Agreement:-

      (i)   may be exercised as often as necessary;

      (ii)  are cumulative and not exclusive of its rights under any Law; and

      (iii)  may be waived only in writing and specifically.

      Delay in exercising or non-exercise of any such right will not constitute
      a waiver of that right.

                                      62
<PAGE>
 
16.2  Delegation: Lessor may delegate to any person or persons all or any of the
      trusts, powers or discretions vested in it by these presents and any such
      delegation may be made upon such terms and conditions and subject to such
      regulations (including power to sub-delegate) as Lessor in its absolute
      discretion thinks fit.

16.3  Certificates: Save where expressly provided in this Agreement, any
      certificate or determination by Lessor as to any rate of interest or as to
      any other amount payable under this Agreement will, in the absence of
      manifest error, be conclusive and binding on Lessee.

16.4  Appropriation: If any sum paid or recovered in respect of the liabilities
      of Lessee under this Agreement is less than the amount then due, Lessor
      may apply that sum to amounts due under this Agreement in such proportions
      and order and generally in such manner as Lessor may determine at its sole
      discretion.

16.5  Currency:

      Lessee acknowledges that the specification of Dollars in this Agreement is
      of the essence and that Dollars shall be the currency of account in any
      and all events.  Lessee waives any right it may have in any jurisdiction
      to pay any amount under this Agreement in a currency other than Dollars.

16.6  Set-off: Lessor may set off any matured obligation owed by Lessee under
      this Agreement, the Other Agreements to which Lessor is a party or under
      any other agreement between Lessor (or any affiliate or associate of
      Lessor) and Lessee (to the extent beneficially owned by Lessor) against
      any obligation (whether or not matured) owed by Lessor to Lessee,
      regardless of the place of payment or currency. If the obligations are in
      different currencies, Lessor may convert either obligation at the market
      rate of exchange available in New York or at its option London for the
      purpose of the set-off. If an obligation is unascertained or unliquidated,
      Lessor may in good faith estimate that obligation and set off in respect
      of the estimate, subject to the relevant party accounting to the other
      when the obligation is ascertained or liquidated. Lessor will not be
      obliged to pay any amounts to Lessee under this Agreement so long as any
      sums which are then due from Lessee under this Agreement, the Other
      Agreements or under any other agreement between Lessor (or any affiliate
      or associate of Lessor) and Lessee remain unpaid and any such amounts
      which would otherwise be due will fall due only if and when Lessee has
      paid all such sums except to the extent Lessor otherwise agrees or sets
      off such amounts against such payment pursuant to the foregoing.

16.7  Severability: If a provision of this Agreement is or becomes illegal,
      invalid or unenforceable in any jurisdiction, that will not affect:-

(a)   the legality, validity or enforceability in that jurisdiction of any other
      provision of this Agreement; or

                                      63
<PAGE>
 
(b)    the legality, validity or enforceability in any other jurisdiction of 
       that or any other provision of this Agreement.

16.8   Remedy: If Lessee fails to comply with any provision of this Agreement,
       Lessor may, without being in any way obliged to do so or responsible for
       so doing and without prejudice to the ability of Lessor to treat the non-
       compliance as a Default or an Event of Default, effect compliance on
       behalf of Lessee, whereupon Lessee shall become liable to pay immediately
       any sums expended by Lessor together with all costs and expenses
       (including legal costs) in connection therewith.

16.9   Expenses: Whether or not the Aircraft is delivered to Lessee pursuant to
       this Agreement, Lessee will pay to Lessor on an After-Tax Basis on
       demand:-

       (a)   all costs associated with perfecting Lessor's rights in the  
             Aircraft and/or this Agreement in the State of Registration, the
             Habitual Base of the Aircraft (and other states as appropriate
             given the operation of the Aircraft), including (but not limited
             to) the provision of legal opinions, tax advice, stamp duties,
             translations and registrations, whether required by Lessor or
             Lessee.

       (b)   all expenses (including legal, professional, and out-of-pocket
             expenses) incurred or payable by Lessor related to any amendment to
             or extension of or other documentation in connection with, or the
             granting of any waiver or consent under this Agreement requested by
             Lessee or the monitoring of compliance by Lessee with this
             Agreement; and

       (c)   all expenses (including legal, survey and other costs) payable or
             incurred by Lessor in contemplation of, or otherwise in connection
             with, the enforcement of or preservation of any of Lessor's or
             Owner's rights under this Agreement, or in respect of the
             repossession of the Aircraft.

       All expenses payable pursuant to this Clause 16.9 will be paid in the
       currency in which they are incurred by Lessor.

16.10  Time of Essence: The time stipulated in this Agreement for all payments
       payable by Lessee to Lessor and the prompt, punctual and performance of
       Lessee's other obligations under this Agreement are of the essence of
       this Agreement.

16.11  Notices: All notices under, or in connection with, this Agreement will,
       unless otherwise stated, be given in writing by letter, facsimile or
       SITA.  Any such notice is deemed effectively to be given as follows:-

       (i)   if by letter, on the earlier of the date when delivered or the 7th
            day after dispatch;

      (ii)  if by facsimile or SITA, when transmitted and full transmission has
            been separately notified by telephone by the transmitting party.

18.    SECTION 1110

       Lessee acknowledges that Lessor would not have entered into this
       Agreement unless it had available to it the benefits of a lessor under
       Section 1110 of Title 11 of the United States Code. Lessee covenants and
       agrees with Lessor that to better ensure the availability of such
       benefits, Lessee shall support any motion, petition or application filed
       by Lessor with any bankruptcy court having jurisdiction over Lessee,
       whereby Lessor seeks recovery of possession of the Aircraft under said
       Section 1110 and shall not in any way oppose such action by Lessor unless
       Lessee shall have complied with the requirements of said Section 1110 to
       be fulfilled in order to entitle Lessee to continued use and possession
       of the Aircraft hereunder. In the event said Section 1110 is amended, or
       if it is repealed and another statute is enacted in lieu thereof, Lessor
       and Lessee agree to amend this Agreement and take such other action not
       inconsistent with this Agreement as Lessor reasonably deems necessary so
       as to afford to Lessor the rights and benefits as such amended or
       substituted statute confers upon owners and lessors of aircraft similarly
       situated to Lessor.

19.    USURY LAWS:  The parties intend to contract in strict compliance with the
       usury Laws of the States of California and Colorado and, to the extent
       applicable, the United States of America. Notwithstanding anything to the
       contrary in the Operative Documents, Lessee will not be obligated to pay
       any interest in excess of the maximum non-usurious interest rate, as in
       effect from time to time, which may by applicable Law be charged,
       contracted for, reserved, received or collected by Lessor in connection
       with the Operative Documents. During any period of time in which the the
       applicable highest lawful rate is lower than the rate specified in
       Clauses 5.11 or 13.2, interest will accrue and be payable at such highest
       lawful rate; however, if at later times such highest lawful rate is
       greater than the rate specified in Clauses 5.11 or 13.2, then Lessee will
       pay interest at the highest lawful rate until the aggregate amount of
       interest paid by Lessee equals the amount of interest that would have
       been payable in accordance with the interest rate specified in Clauses
       5.11 or 13.2.

                             INSURANCE REQUIREMENTS

            The Insurances required to be maintained are as follows:-

(a)   HULL ALL RISKS of Loss or Damage whilst flying and on the ground with
      respect to the Aircraft on an "agreed value basis" for the Agreed Value
      and with a deductible not exceeding the Deductible Amount set forth in
      Letter Agreement No. 1, or such other amount agreed by Lessor from time to
      time;

(b)   HULL WAR AND ALLIED PERILS, being such risks excluded from the Hull All
      Risks Policy to the fullest extent available from the leading
      international insurance markets including confiscation and requisition by
      the State of Registration for the Agreed Value, however, when the Aircraft
      is being operated solely in or over the United States of America and/or
      Canada, coverage may be limited to such perils as are customarily insured
      by comparable airlines, operating similar equipment in similar
      circumstances;

(c)   ALL RISKS (INCLUDING WAR AND ALLIED RISK except when on the ground or in
      transit other than by air) property insurance on all Engines and Parts
      when not installed on the Aircraft on an "agreed value" basis for their
      full replacement value and including engine test and running risks;

(d)   AIRCRAFT THIRD PARTY, PROPERTY DAMAGE, PASSENGER, BAGGAGE, CARGO AND MAIL
      AND AIRLINE GENERAL THIRD PARTY (INCLUDING PRODUCTS) LEGAL LIABILITY for a
      Combined Single Limit (Bodily Injury/Property Damage) of an amount not
      less than the Minimum Liability Coverage for the time being any one
      occurrence (but in respect of products and personal injury liability this
      limit may be an aggregate limit for any and all losses occurring during
      the currency of the policy). War and Allied Risks are also to be covered
      under the Policy in  line with prudent market practice for comparable
      airlines, operating similar equipment in similar circumstances;

(e)   All required hull and spares insurance (as specified above), so far as it
      relates to the Aircraft will: -

      (i)     name Lessor and its successors and assigns as additional assureds 
              for their respective rights and interests, warranted, each as to
              itself only, no operational interest;

      (ii)    provide that any loss will be settled jointly with Lessor and 
              Lessee and will be payable in Dollars to Lessor except where the
              loss does not exceed the Damage Notification Threshold, and Lessor
              has not notified the insurers to the contrary, in which case the
              loss will be settled with and paid to Lessee;

                                      4-1
<PAGE>
 
      (iii)   if separate Hull "all risks" and "war risks" insurances are
              arranged, include a 50/50 provision in accordance with market
              practice (AVS. 103 is the current market language);

      (iv)    confirm that the insurers are not entitled to replace the Aircraft
              in the event of an insured Event of Loss;

      (v)     confirm that the insurers will not obtain a valid discharge of the
              obligations under the Insurances by payment to the broker,
              notwithstanding market practice to the contrary;

(f)   All required liability insurances (specified above) will:-

      (i)     include Lessor, GECASI, GECASL and their respective successors 
              and assigns and their respective shareholders, subsidiaries,
              directors, officers, agents, employees and indemnitees as
              additional insureds for their respective rights and interests,
              warranted, each as to itself only, no operational interest;

      (ii)    include a Severability of Interest Clause which provides that the
              insurance, except for the limit of liability, will operate to give
              each assured the same protection as if there was a separate policy
              issued to each assured;

      (iii)   contain a provision confirming that the policy is primary without
              right of contribution and the liability of the insurers will not
              be affected by any other insurance of which Lessor or Lessee have
              the benefit so as to reduce the amount payable to the additional
              insureds under such policies;

(g)   All Insurances will:-

      (i)     be in accordance with normal industry practice of persons 
              operating similar aircraft in similar circumstances;

      (ii)    provide cover denominated in Dollars and any other currencies 
              which Lessor may reasonably require in relation to liability 
              insurance;

      (iii)   operate on a worldwide basis subject to such limitations and
              exclusions as Lessor may agree;

      (iv)    acknowledge the insurer is aware (and has seen a copy) of this
              Agreement and that the Aircraft is owned by Lessor;

      (v)     provide that, in relation to the interests of each of the 
              additional assureds the Insurances will not be invalidated by any
              act or omission by Lessee, or any other person other than the
              respective additional assured seeking protection and shall insure
              the interests of each of the additional assureds regardless of any
              breach or violation by Lessee, or any other person other than the

                                      4-2
<PAGE>
 
              respective additional assured seeking protection of any warranty,
              declaration or condition, contained in such Insurances;

      agreed.  In the event (a) Lessee is unwilling or unable to accept delivery
      of the Aircraft on the date notified by Lessor as the Delivery Date, and
      (b) the Aircraft meets Delivery Condition Requirements then Lessee's
      obligation to pay Rent hereunder shall commence on such Delivery Date
      notwithstanding that Lessee has not accepted possession of the Aircraft.

4.3   Delayed Delivery: If owing to:-

(a)   any seller, manufacturer or existing lessee of the Aircraft delaying in
      the delivery of, or failing to deliver, the Aircraft to Lessor for any
      reason (other than because of any default of Lessor in the performance of
      its obligations under an agreement with that seller, manufacturer or
      lessee unless the default arises from any act or omission of Lessee)
      whether or not in circumstances entitling that seller, manufacturer or
      lessee to terminate that agreement;

(b)   any purchase agreement for the Aircraft terminating prior to delivery of
      the Aircraft (other than because of any default of Lessor in the
      performance of its obligations under that agreement unless the default
      arises from any act or omission of Lessee);

(c)   any Excusable Delay; or

                                       24
<PAGE>
 
(d)   notification of any defect or non-conformity pursuant to Clause 4.5;

      Lessor delays in the delivery of, or fails to deliver, the Aircraft under
      this Agreement:-

      (i)   Lessor will not be responsible for any losses, including loss of
            profit, costs or expenses arising from or in connection with the
            delay or failure suffered or incurred by Lessee;

      (ii)  subject to Clause 4.5, Lessee will not be entitled to terminate this
            Agreement or to reject the Aircraft when tendered for delivery by
            Lessor, on the grounds of any such delay;

      (iii) in the case of termination of a purchase agreement, Lessor may at
            any time after the termination terminate this Agreement; and

      (iv)  upon any such termination or termination pursuant to Clause 4.5
            neither Lessor nor Lessee will have any further obligation to the
            other under this Agreement other than as expressly set out in this
            Agreement, except that Lessor will repay to Lessee the Deposit and
            shall return the warrant certificate representing the Warrant.

4.4   Licenses: Lessee will at its expense obtain all licenses, permits and
      approvals which may be necessary to export the Aircraft from the Delivery
      Location. Lessor will furnish such data and information as may be
      reasonably requested by Lessee in connection with obtaining any such
      license, permit or approval.

4.5   Inspection: Prior to the Delivery Date, subject to any applicable purchase
      or lease agreement, Lessor will give Lessee an opportunity:-

(a)   to inspect the Aircraft at the Delivery Location; and

(b)   to assign up to 2 representatives to participate as observers in a
      demonstration flight to demonstrate the condition of the Aircraft.

      If Lessee notifies Lessor promptly prior to the Delivery Date of any
      defect or non-conformity with Schedule 1 observed during the inspection or
      demonstration flight, Lessor will correct or procure the correction of the
      defect or non-conformity as promptly as practicable (except to the extent
      otherwise agreed or to the extent in the opinion of Lessor it is
      impracticable or prohibitively expensive to do so).  Subject to Clause
      4.3, Lessor may postpone the Delivery Date in such a case to the date
      which Lessor notifies Lessee that the defect or non-conformity has been
      rectified.  Lessee will be entitled to terminate this Agreement if Lessor
      notifies it that Lessor does not intend to correct the defect or non-
      conformity.

4.6   Indemnity: Lessee will indemnify and hold harmless the Indemnitees from
      and against all Claims (as defined in Clause 10) arising from death or
      injury to any observer or any

      Rental Period shall be paid on the Business Day immediately preceding the
      date on which such Rental Period commences.

     writing.

5.6  Withholding: All payments by Lessee pursuant to the Operative Documents
     shall be free of all withholdings of any nature whatsoever except to the
     extent otherwise required by Law, and if any such withholding is so
     required, Lessee shall pay on an After-Tax Basis an additional amount such
     that after the deduction of all amounts required to be withheld, the net
     amount actually received by Lessor on an After-Tax Basis will equal the
     amount that Lessor would have received on an After-Tax Basis if such
     withholding had not been required; provided, however, that if Lessee pays
     any such additional amount to compensate for the withholding of any Lessor
     Tax, Lessor shall repay to Lessee within 30 days after receipt of Lessee's
     written request therefor (which request shall include a description in
     reasonable detail of the Lessor Tax involved and the calculation of the
     additional amount to be repaid) the amount of such additional amount to the
     extent attributable to any Lessor Tax.

            for the Warrant and the side letter dated as of April 3, 1996

            permitted by applicable Law) at or before the time prescribed by
            applicable Law.  After any payment by Lessee of any Tax directly to
            a taxing authority, Lessee shall furnish to Lessor, on request, a
            certified copy of a receipt for Lessee's payment of such Tax or such
            other evidence of payment of such Tax as is reasonably obtainable by
            Lessee and reasonably acceptable to Lessor.

      (iii) Any amount payable by Lessee to an Indemnitee pursuant to Clause
            5.7 shall be paid within ten days after receipt of a written demand
            therefor from the relevant Indemnitee accompanied by a written
            statement describing in reasonable detail the basis for such
            indemnity and the computation of the amount so payable, provided
            that if an amount of any indemnified Tax is being contested in

            (and shall continue to perform) all its obligations under Clause
            5.12 with respect to such contest, then payment of the indemnity
            with respect to such Tax under Clause 5.12 shall , at Lessee's
            election, be deferred until the date the contest has been completed.

5.8. Sales and Use Taxes:

(a)   Lessee shall pay to Lessor (or, if permitted by applicable Law and if
      requested by Lessor, Lessee shall pay to the relevant tax authority for
      the account of Lessor), in addition to the amounts specified as "Rent" in
      Letter Agreement No. 1:

      (i)   all sales, use, rental, value added, goods and services and similar
            taxes ("Sales Taxes") required to be paid to the tax authority of
            the jurisdiction in which the Delivery Location is situated or to
            the jurisdiction in which the Aircraft is habitually based with
            respect to the lease of the Aircraft to Lessee pursuant to the
            Operative Documents unless Lessee delivers to Lessor on or prior to
            the Delivery Date such exemption certificate or other document as
            may be acceptable to Lessor to evidence Lessee's entitlement to
            exemption from all Sales Taxes imposed by such jurisdiction with
            respect to the lease of the Aircraft pursuant to the Operative
            Documents; and

                                       28
<PAGE>
 
      (ii)  all Sales Taxes required to be paid to the tax authority of any
            jurisdiction in which the Aircraft may be used, operated or
            otherwise located from time to time unless Lessee delivers to Lessor
            such exemption certificates or other documents as may be required by
            applicable Law to evidence Lessee's entitlement to exemption from
            all Sales Taxes imposed by each such jurisdiction with respect to
            the lease of the Aircraft pursuant to the Operative Documents.

(b)   Lessee will cooperate with Lessor in connection with the preparation and
      filing of any exemption application or similar document that is reasonably
      necessary or desirable under applicable Law to avoid the imposition of any
      Sales Taxes with respect to the transactions contemplated by the Operative
      Documents.

(c)   The specific obligations with respect to sales and use taxes set forth in
      this Clause 5.8 are in addition to, and are not in substitution for, the
      Lessee's obligation to indemnify for sales and use taxes pursuant to
      Clause 5.7.

5.9   Information:

(a)   If Lessee is required by any applicable Law, or by any third party, to
      deliver any report or return in connection with any Taxes for which Lessee
      would be obligated to indemnify Lessor under the Operative Documents,
      Lessee will complete the same and, on request, supply a copy of the report
      or return to Lessor.

(b)   If any report, return or statement is required to be made by Lessor with
      respect to any Tax for which there is an indemnity obligation of Lessee
      under this Clause 5, Lessee will promptly notify Lessor of the requirement
      and:

      (i)  if permitted by applicable Law, make and timely file such report,
           return or statement (except for any report, return or statement that
           Lessor has notified Lessee that Lessor intends to prepare and file),
           prepare such return in such manner as will show the ownership of the
           Aircraft in Lessor if required or appropriate, and provide Lessor
           upon request a copy of each such report, return or statement filed by
           Lessee, or

      (ii) if Lessee is not permitted by applicable Law to file any such
           report, return or statement, Lessee will prepare and deliver to
           Lessor a proposed form of such report, return or statement within a
           reasonable time prior to the time such report, return or statement
           is to be filed.

      Lessee will provide such information and documents as Lessor may
      reasonably request to enable Lessor to comply with its tax filing, audit
      and litigation obligations.

5.10  Indemnity Payments to be Made on an After-Tax Basis: Lessee agrees that,
      with respect to any payment or indemnity pursuant to Clause 5.7 (Tax
      Indemnity), Clause 5.8 (Sales and Use Taxes) or Clause 10 (Indemnity) to
      or for the benefit of any Indemnitee, Lessee's indemnity obligations shall
      include such amount as may be necessary to hold such Indemnitee harmless
      on an After-Tax Basis from all Taxes required to be paid by 

                                       29
<PAGE>
 
      such Indemnitee with respect to such payment or indemnity (including any
      payments pursuant to this Clause 5.10), determined based on the assumption
      that at the time each such payment or indemnity accrues to the relevant
      Indemnitee, such payment or indemnity will be subject to (i) United States
      Federal income tax at the highest marginal statutory tax rate applicable
      to corporations, (ii) United States state and local income taxes at the
      composite of the highest marginal statutory tax rates applicable to the
      Indemnitee and (iii) income taxes (if any) imposed by countries outside
      the United States at the actual rates imposed on the relevant Indemnitee.

5.11  Default Interest: If Lessee fails to pay any amount payable under this
      Agreement on the due date, Lessee will pay on demand from time to time to
      Lessor interest (both before and after judgment) on that amount, from the
      due date to the date of payment in full by Lessee to Lessor, at the
      Interest Rate specified in Letter Agreement No. 1; provided, however, that
      in no event shall such rate exceed the maximum permitted by Law.  All such
      interest will be compounded monthly and calculated on the basis of the
      actual number of days elapsed in the month assuming a 30 day month and a
      360 day year.

5.12  Contest:

(a)   If an Indemnitee receives a written claim for any Tax for which Lessee
      would be required to pay an indemnity pursuant to Clause 5.7 or Clause
      5.8, such Indemnitee shall notify Lessee promptly of such claim, provided
      that any failure to provide such notice will not relieve Lessee of any
      indemnification obligation pursuant to Clause 5.7 or Clause 5.8.  If
      requested by Lessee in writing promptly after receipt of such Indemnitee's
      notice, such Indemnitee shall, upon receipt of indemnity satisfactory to
      it and at the expense of Lessee (including, without limitation, all costs,
      expenses, legal and accountants' fees and disbursements, and penalties,
      interest and additions to tax incurred in contesting such claim) in good
      faith contest or (if permitted by applicable Law) permit Lessee to contest
      such claim by (i) resisting payment thereof if practicable and
      appropriate, (ii) not paying the same except under protest if protest is
      necessary and proper, or (iii) if payment is made, using reasonable
      efforts to obtain a refund of such Taxes in appropriate administrative and
      judicial proceedings.  Such Indemnitee shall determine the method of any
      contest conducted by such Indemnitee and (in good faith consultation with
      Lessee) control the conduct thereof.  Lessee shall determine the method of
      any contest conducted by Lessee and (in good faith consultation with such
      Indemnitee) control the conduct thereof.  Lessee shall pay in full all
      payments of Rent and other amounts payable pursuant to the Operative
      Documents, without reduction for or on account of any Tax, while such
      contest is continuing.  Such Indemnitee shall not be required to contest,
      or to continue to contest, a claim for Taxes under this Clause 5.12 if (x)
      such contest would result in a risk of criminal penalties or of a sale,
      forfeiture or loss of, or the imposition of a Lien (other than a Permitted
      Lien) on, the Aircraft, or (y) Lessee shall not have furnished an opinion
      of independent tax counsel selected by such Indemnitee and reasonably
      satisfactory to Lessee, that a reasonable basis exists for such contest,
      or (z) a Default or an Event of Default shall be continuing (unless Lessee
      shall have provided security reasonably satisfactory to such Indemnitee
      securing Lessee's performance of its obligations under this Clause 5).  If
      such Indemnitee contests any claim for Taxes by 

                                       30
<PAGE>
 
      making a payment and seeking a refund thereof, then Lessee shall advance
      to such Indemnitee, on an interest-free basis, an amount equal to the
      Taxes to be paid by such Indemnitee in connection with the contest and
      shall indemnify such Indemnitee on an After-Tax Basis for any adverse tax
      consequences to such Indemnitee of such interest-free advance. Upon the
      final determination of any contest pursuant to this Clause 5.12 in respect
      of any Taxes for which Lessee shall have made an advance to such
      Indemnitee in accordance with the immediately preceding sentence, the
      amount of Lessee's obligation shall be determined as if such advance had
      not been made; any indemnity obligation of Lessee to such Indemnitee under
      this Clause 5 and such Indemnitee's obligation to repay the advance will
      be satisfied first by setoff against each other, and any difference owing
      by either party shall be paid within ten days after such final
      determination.

(b)   If an Indemnitee obtains a refund of all or any part of any Taxes for
      which a full indemnity was paid by Lessee, such Indemnitee shall pay
      Lessee the amount of such refund, reduced by any Taxes imposed on such
      Indemnitee on receipt or accrual of such refund and increased by any Taxes
      saved by such Indemnitee by reason of the deductibility of such payment by
      such Indemnitee.  If, in addition to such refund, such Indemnitee receives
      an amount of interest on such refund, such Indemnitee shall pay to Lessee
      the portion of such interest which is fairly attributable to such refund,
      reduced by any Taxes imposed on such Indemnitee on receipt or accrual of
      such interest and increased by any Taxes saved by reason of the
      deductibility of such payment by such Indemnitee.  Such Indemnitee shall
      not be required to make any payment to Lessee pursuant to this Clause 5.12
      if, and for so long as, an Event of Default shall have occurred and be
      continuing.

(c)   Any Indemnitee in its sole discretion (by written notice to Lessee) may
      waive its rights to indemnification pursuant to Clause 5.7 with respect to
      any claim for any Tax and may refrain from contesting or continuing the
      contest of such claim, in which event Lessee shall have no obligation to
      indemnify such Indemnitee for the Taxes that are the subject of such
      claim.  If an Indemnitee agrees to a settlement of any contest conducted
      pursuant to this Clause 5.11 without the prior written consent of Lessee,
      which consent shall not be unreasonably withheld, then Lessor shall be
      deemed to have waived its rights to the indemnification provided for in
      Clause 5.7 with respect to the Tax liability accepted in such settlement.

5.13  Net Lease: This Agreement is a net lease.  Lessee's obligations under this
      Agreement are absolute and unconditional irrespective of any contingency
      whatsoever including (but not limited to):-

(a)   any right of set-off, counterclaim, recoupment, defense or other right
      which either party to this Agreement may have against the other;

(b)   any unavailability of the Aircraft for any reason, including, but not
      limited to, a requisition of the Aircraft or any prohibition or
      interruption of or interference with or other restriction against Lessee's
      use, operation or possession of the Aircraft;

                                       31
<PAGE>
 
(c)   any lack or invalidity of title or any other defect in title,
      airworthiness, merchantability, fitness for any purpose, condition,
      design, or operation of any kind or nature of the Aircraft for any
      particular use or trade, or for registration or documentation under the
      laws of any relevant jurisdiction, or any Event of Loss in respect of or
      any damage to the Aircraft;

(d)   any insolvency, bankruptcy, reorganization, arrangement, readjustment of
      debt, dissolution, liquidation or similar proceedings by or against Lessor
      or Lessee;

(e)   any invalidity or unenforceability or lack of due authorization of, or
      other defect in, this Agreement;

(f)   and Security Interests with respect to the Aircraft or Taxes; and/or

(g)   any other cause which but for this provision would or might otherwise have
      the effect of terminating or in any way affecting any obligation of Lessee
      under this Agreement.

5.14  Security

(a)   To the fullest extent permitted by Law and by way of continuing security
      Lessee as sole beneficial owner charges the Deposit and the Maintenance
      Reserves and all rights of Lessee to payment thereof and the debt
      represented thereby (the "Charged Monies") to Lessor by way of first fixed
      charge as security for Lessee's obligations and liabilities under this
      Agreement and the Other Agreements to which Lessor or any affiliate or
      associate thereof (which for clarification does not include GPA Group PLC,
      Airplane Holdings Limited or any affiliate or associate, successor thereto
      or assignee thereof ) is a party (the "Secured Liabilities").  Except as
      expressly permitted under this Agreement, Lessee will not be entitled to
      payment of the Charged Monies.  Lessee will not assign, transfer or
      otherwise dispose of all or part of its rights in the Charged Monies and
      it will enter into any additional documents and instruments necessary or
      advisable to evidence, create or perfect Lessor's rights to the Charged
      Monies;

(b)   If Lessee fails to comply with any provision of this Agreement or any
      Event of Default has occurred and is continuing, in addition to all rights
      and remedies accorded to Lessor elsewhere in this Agreement and under Law
      as a secured party in respect of the Charged Monies, Lessor may
      immediately or at any time thereafter, without prior notice to Lessee:-

      (i)   set-off all or any part of the Secured Liabilities against the
            liabilities of Lessor in respect of the Charged Monies;  or

      (ii)  apply or appropriate the Charged Monies in or towards the payment or
            discharge of the Secured Liabilities in such order as Lessor sees
            fit; and

(c)   If Lessor has exercised the set-off described in sub-clause (b) above,
      Lessee shall, following a demand in writing from Lessor, restore the
      Charged Monies to the level at which they stood immediately prior to such
      set-off.

 6.   MANUFACTURER'S WARRANTIES

6.1   Assignment: Notwithstanding this Agreement, Lessor will remain entitled to
      the benefit of each warranty, express or implied, with respect to the
      Aircraft, any Engine or Part so far as concerns any manufacturer, vendor,
      subcontractor or supplier. Except to the extent Lessor otherwise directs,
      Lessor hereby authorizes Lessee to pursue any claim thereunder in relation
      to defects affecting the Aircraft, any Engine or Part and Lessee agrees
      diligently to pursue any such claim which arises at its own cost. Lessee
      will notify Lessor promptly upon becoming aware of any such claim.

6.2   Proceeds: Except to the extent Lessor otherwise agrees in a particular
      case, all proceeds of any such claim will be paid directly to Lessor but
      if and to the extent that such claim relates:-

(a)   to defects affecting the Aircraft which Lessee has rectified; or

(b)   to compensation for loss of use of the Aircraft, an Engine or any Part
      during the Term; and

      provided no Default has occurred and is continuing the proceeds will be
      paid to Lessee by Lessor but in the case of (a) above only on receipt of
      evidence satisfactory to Lessor that Lessee has rectified the relevant
      defect.

6.3   Parts: Except to the extent Lessor otherwise agrees in a particular case,
      Lessee will procure that all engines, components, furnishings or equipment
      provided by the manufacturer, vendor, subcontractor or supplier in
      replacement of a defective Engine or Part pursuant to the terms of any
      warranty will be installed promptly by Lessee and that title thereto free
      of Security Interests vests in Lessor.  On installation each part will be
      deemed to be a Part.  In the case of a Replacement Engine, Lessee will
      satisfy and perform each of the conditions and covenants set forth in
      Clause 11.1(c), and upon satisfaction of such conditions, such Replacement
      Engine will be deemed an "Engine" for all purposes of this Agreement.

6.4   Agreement: To the extent any warranties relating to the Aircraft are made
      available under an agreement between any manufacturer, vendor,
      subcontractor or supplier and Lessee, this Clause 6 is subject to that
      agreement.  However Lessee will:-

(a)   pay the proceeds of any claim thereunder to Lessor to be applied pursuant
      to Clause 6.2 and pending such payment will hold the claim and the
      proceeds on trust for Lessor; and

(b)   Lessee will take all such steps as are necessary at the end of the Term to
      ensure the benefit of any of those warranties which have not expired are
      vested in Lessor.

7.    LESSOR'S COVENANTS

7.1   Quiet Enjoyment: Lessor will not interfere with the quiet use, possession
      and enjoyment of the Aircraft by Lessee but the exercise by Lessor of its
      rights under or in connection with this Agreement will not constitute such
      an interference.  Lessor will procure at Lessee's request an undertaking
      of quiet enjoyment for the benefit of Lessee with respect to any
      prospective Lessor Lien.

7.2   Release of Maintenance Reserves: Provided no Default has occurred and is
      continuing Lessor will release funds to Lessee from the Maintenance

      and

                                       34

(d)   with respect to the Landing Gear, the performance in accordance with this
      Agreement, of all work on the landing gear in the nature of overhaul and

      condition required by this Agreement; or

      or become payable under this Agreement, the other Operative Documents or
      the Other Agreements to which Lessor or any affiliate or associate,

      Indemnitees in the Insurances, the Aircraft, any Engine or any Part.

8.4   Taxes and other Outgoings: Lessee will promptly pay:-

(a)   all license and registration fees, Taxes (other than Lessor Taxes) and

      is being contested in good faith by appropriate proceedings, in respect of
      which adequate resources have been provided by Lessee and non-payment of
      which does not give rise to any material likelihood of the Aircraft or any
      interest therein being sold, forfeited or otherwise lost or of criminal
      liability on the part of Lessor.

                                       38

      (ii)  as part of a normal engine or part rotation program; or

      (iii) for the purpose of making such modifications to the Engine or the

      respect to an Engine, title to such Engine shall remain vested in Lessor.

8.13  Installation of Engines and Parts: Lessee will:-

(a)   ensure that, except as permitted by this Agreement, no engine or part is
      installed on the Aircraft unless:-

      (i)   in the case of an engine, it is an engine of the same model as, or
            an improved or advanced version of the Engine it replaces, which is
            in the same or better operating condition, has substantially similar
            hours available until the next scheduled checks, inspections,
            overhauls and shop visits and has the same or greater value and
            utility as the replaced Engine;

      (ii)  in the case of a part, it is in as good operating condition, has
            substantially similar hours available until the next scheduled
            checks, inspections, overhauls and shop visits, is of the same or a
            more advanced make and model and is of the same interchangeable
            modification status as the replaced Part;

      (iv)  in each case, Lessee has full details as to its source and
            maintenance records;

(b)   if no Default has occurred which is continuing, be entitled to install any

            that engine or part is required to be installed on the Aircraft, a
            replacement engine or, as the case may be, part complying with the
            requirements of Clause 8.13(a);

      (ii)  it would result in an unreasonable disruption of the operation of
            the Aircraft and/or the business of Lessee to ground the Aircraft
            until an engine or part, as the case may be, complying with Clause
            8.13(a) becomes available for installation on the Aircraft; and

      (iii) as soon as practicable after installation of the same on the

            Part replaced by it or by an engine or part, as the case may be,
            complying with Clause 8.13(a).

8.14  Non-Installed Engines and Parts: Lessee will:-

(a)   ensure that any Engine or Part which is not installed on the Aircraft (or

      permitted by this Agreement, properly and safely stored, and kept free
      from Security Interests;

(b)   notify Lessor whenever any Engine is removed from the Aircraft and, from
      time to time, on request procure that any person to whom possession of an
      Engine is given acknowledges in writing to Lessor, in form and substance
      satisfactory to Lessor, that it will respect the interest of  Lessor in
      the Engine and will not seek to exercise any rights whatsoever in relation
      to it;

(c)   (notwithstanding the foregoing provisions of this sub-clause), be
      permitted, if no Default has occurred and is continuing, to install any
      Engine or Part on an aircraft, or in the case of a Part on an engine:-

      (i)   owned and operated by Lessee free from Security Interests;  or

      (ii)  leased or hired to Lessee pursuant to a lease or conditional sale
            agreement on a long-term basis and on terms whereby Lessee has full
            operational control of that aircraft or engine;  or

      (iii) acquired by Lessee and/or financed or refinanced, and operated by
            Lessee, on terms that ownership of that aircraft or engine, as the
            case may be, pursuant to 

                                       44
<PAGE>
 
            a lease or conditional sale agreement, or a Security Interest
            therein, is vested in or held by any other Person;

provided that in the case of (ii) and (iii):-

      (1)   the terms of any such lease, conditional sale agreement or Security
            Interest will not have the effect of prejudicing the interest of
            Lessor in that Engine or Part; and

      (2)   the lessor under such lease, the seller under such conditional sale
            agreement or the holder of such Security Interest, as the case may
            be, has confirmed and acknowledged in writing to Lessor, in form and
            substance satisfactory to Lessor, that it will respect the interest
            of Lessor in respect of that Engine or Part and that it will not
            seek to exercise any rights whatsoever in relation thereto.

      "Equipment Change"), except for an Equipment Change which:-

      (i)   is expressly permitted by this Agreement, or

      (ii)  has the prior written approval of Lessor and which does not diminish
            the value, utility, condition, or airworthiness of the Aircraft;

(b)   So long as a Default has not occurred and is continuing, Lessee may remove
      any Equipment Change if it can be removed from the Aircraft without
      diminishing or impairing the value, utility, condition or airworthiness of
      the Aircraft; and

(c)   Lessee shall indemnify Lessor on an After-Tax Basis for any and all Taxes
      payable by Lessor as the case may be, as a result of an Equipment Change.

8.17  Title on an Equipment Change:

(a)   Title to all Parts installed on the Aircraft whether by way of
      replacement, as the result of an Equipment Change or otherwise (except
      those installed pursuant to Clause 8.13(b)) will on installation, without
      further act, vest in Lessor subject to this Agreement free and clear of
      all Security Interests. Lessee will at its own expense take all such steps
      and execute, and procure the execution of, all such instruments as Lessor
      may require and which are necessary to ensure that title so passes  to
      Lessor according to all applicable Laws.  At any time when requested by
      Lessor, Lessee will provide evidence to Lessor's 

                                       45
<PAGE>
 
      satisfaction (including the provision, if required, to Lessor of one or
      more legal opinions) that title has so passed to Lessor;

      the Aircraft to its condition prior to that Equipment Change; and

(c)   Except as referred to in Clause 8.17(b) any Engine or Part at any time
      removed from the Aircraft will remain the property of Lessor until a
      replacement has been made in accordance with this Agreement and until
      title in that replacement has passed, according to applicable Laws, to
      Lessor subject to this Agreement and free of all Security Interests.  Upon
      title to such replacement so passing to Lessor, title to the replaced
      Engine or Part, will, provided no Default has occurred and is continuing,
      pass to Lessee.

8.18  Third Party: Lessee will procure that no person (other than Lessor) will
      act in any manner inconsistent with its obligations under this Agreement
      and that all persons will comply with those obligations as if references
      to "Lessee" included a separate reference to those persons.

9.    INSURANCE

9.1   Insurances: Lessee will maintain in full force during the Term, and
      thereafter as expressly required in this Agreement, insurances in respect
      of the Aircraft in form and substance satisfactory to Lessor (the
      "Insurances" which expression includes, where the context so admits, any
      relevant re-insurance(s)) through such brokers and with such insurers and
      having such deductibles and being subject to such exclusions as may be
      approved by Lessor from time to time. The Insurances will be effected
      either:-

(a)   on a direct basis with insurers of recognized standing who normally
      participate in aviation insurances in the leading international insurance
      markets and led by reputable underwriter(s) approved by Lessor; or

(b)   with a single insurer or group of insurers approved by Lessor who does not
      retain the risk but effects substantial reinsurance with reinsurers in the
      leading international insurance markets and through brokers each of
      recognized standing and acceptable to Lessor for a percentage acceptable
      to Lessor of all risks insured (the "Reinsurances").

9.2   Requirements: Lessor's current requirements as to required Insurances are
      as specified in this Clause and in Schedule 4. Lessor may from time to
      time stipulate other requirements for the Insurances so that the scope and
      level of cover is maintained in line with best industry practice and the
      interests of Lessor protected.

9.3   Change: If at any time Lessor wishes to revoke its approval of any
      insurer, reinsurer, insurance or reinsurance, Lessor and/or its brokers
      will consult with Lessee and Lessee's brokers (as for the time being
      approved by Lessor) regarding whether that approval should be revoked to
      protect the interests of the parties insured. If, following the
      consultation, Lessor considers that any change should be made, Lessee will
      then arrange or procure the arrangement of alternative cover satisfactory
      to Lessor.

                                       46

(a)   ensure that all legal requirements as to insurance of the Aircraft, any
      Engine or any Part which may from time to time be imposed by the laws of
      the State of Registration or any state to, from or over which the Aircraft
      may be flown, in so far as they affect or concern the operation of the
      Aircraft, are complied with and in particular those requirements
      compliance with which is necessary to ensure that (i) the Aircraft is not
      in danger of detention or forfeiture, (ii) the Insurances remain valid and
      in full force and effect, and (iii) the interests of the Indemnitees in
      the Insurances and the Aircraft or any Part are not thereby prejudiced;

      for any purpose or in any manner not covered by the Insurances or outside
      any geographical limit imposed by the Insurances;

(c)   comply with the terms and conditions of each policy of the Insurances and
      not do, consent or agree to any act or omission which:-

      (i)   invalidates or may invalidate the Insurances; or

      (ii)  renders or may render void or voidable the whole or any part of any
            of the Insurances; or

      (iii) brings any particular liability within the scope of an exclusion or
            exception to the Insurances;

(d)   not take out without the prior written approval of Lessor any insurance or
      reinsurance in respect of the Aircraft other than those required under
      this Agreement unless relating solely to hull total loss, business
      interruption, profit commission and deductible risk;

(e)   commence renewal procedures at least 30 days prior to expiry of any of the
      Insurances and provide to Lessor:-

      (iii) certificates of insurance (and where appropriate certificates of
            reinsurance), and broker's (and any reinsurance brokers') letter of
            undertaking in a form acceptable to Lessor in English, detailing the
            coverage and confirming the insurers' (and any reinsurers')
            agreement to the specified insurance requirements of this Agreement
            within 7 days after each renewal date;

(f)         on request, provide to Lessor copies of documents or other
            information evidencing the Insurances;

                                       47
<PAGE>
 
(g)   on request, provide to Lessor evidence that the Insurance premiums have
      been paid;

(h)   not make any modification or alteration to the Insurances material and
      adverse to the interests of any of the Indemnitees;

(i)   be responsible for any deductible under the Insurances; and

(j)   provide any other insurance and reinsurance related information, or
      assistance, in respect of the Insurances as Lessor may reasonably require.

9.5   Failure to Insure: If Lessee fails to maintain the Insurances in
      compliance with this Agreement, each of the Indemnitees will be entitled
      but not bound, (without prejudice to any other rights of Lessor under this
      Agreement):-

(a)   to pay the premiums due or to effect and maintain insurances satisfactory
      to it or otherwise remedy Lessee's failure in such manner (including,
      without limitation to effect and maintain an "owner's interest" policy) as
      it considers appropriate. Any sums so expended by it will become
      immediately due and payable by Lessee to Lessor on an After-Tax Basis
      together with interest thereon at the rate specified in Clause 5.11, from
      the date of expenditure by it up to the date of reimbursement by Lessee;
      and

(b)   at any time while such failure is continuing to require the Aircraft to
      remain at any airport or to proceed to and remain at any airport
      designated by it until the failure is remedied to its satisfaction.

9.6   Continuing Indemnity: Lessee shall effect and maintain insurance after the
      Expiry Date with respect to its liability under the Indemnity in Clause 10
      for 2 years which provides for each Indemnitee to be named as additional
      insured.  Lessee's obligation in this Clause shall not be affected by
      Lessee ceasing to be lessee of the Aircraft and/or any of the Indemnitees
      ceasing to have any interest in respect of the Aircraft.

9.7   Application of Insurance Proceeds:-

As between Lessor and Lessee:-

(a)   all insurance payments received as the result of an Event of Loss or
      Engine Event of Loss occurring during the Term will be paid to Lessor and
      Lessor will pay the balance of those amounts to Lessee after deduction of
      all amounts which may be or become payable by Lessee to Lessor under this
      Agreement (including under Clause 11.1(b));

(b)   all insurance proceeds of any property, damage or loss to the Aircraft,
      any Engine or any Part occurring during the Term not constituting an Event
      of Loss or Engine Event of Loss and in excess of the Damage Notification
      Threshold will be applied in payment (or to reimburse Lessee) for repairs
      or replacement property upon Lessor being satisfied that the repairs or
      replacement have been effected in accordance with this Agreement.
      Insurance proceeds in amounts below the Damage Notification Threshold may
      be paid by the insurer directly to Lessee. Any balance remaining may be
      retained by Lessor;

                                       48

(c)   all insurance proceeds in respect of third party liability will, except to
      the extent paid by the insurers to the relevant third party, be paid to
      Lessor to be paid directly in satisfaction of the relevant liability or to
      Lessee in reimbursement of any payment so made; and

(d)   notwithstanding Clauses 9.7(a), (b) or (c), if at the time of the payment
      of any such insurance proceeds a Default has occurred and is continuing,
      all such proceeds will be paid to or retained by Lessor to be applied
      toward payment of any amounts which may be or become payable by Lessee in
      such order as Lessor sees fit or as Lessor may elect.

      To the extent insurance proceeds are paid to Lessee, Lessee agrees to
      comply with the foregoing provisions and apply or pay over such proceeds
      as so required.

10.   INDEMNITY

10.1  GENERAL:  LESSEE AGREES TO DEFEND, INDEMNIFY AND HOLD HARMLESS THE
      INDEMNITEES ON AN AFTER-TAX BASIS FROM AND AGAINST ANY AND ALL CLAIMS,
      PROCEEDINGS, LOSSES, LIABILITIES, SUITS, JUDGMENTS, COSTS, EXPENSES,
      PENALTIES OR FINES (EACH A "CLAIM") (REGARDLESS OF WHEN THE SAME IS MADE
      OR INCURRED, WHETHER DURING OR AFTER THE TERM (BUT NOT BEFORE)):-

      (A)   WHICH MAY AT ANY TIME BE SUFFERED OR INCURRED DIRECTLY OR INDIRECTLY
            AS A RESULT OF OR CONNECTED WITH THE POSSESSION, DELIVERY,
            PERFORMANCE, MANAGEMENT, OWNERSHIP, REGISTRATION, CONTROL,
            MAINTENANCE, CONDITION, SERVICE, REPAIR, OVERHAUL, LEASING, USE,
            OPERATION OR RETURN OF THE AIRCRAFT, ANY ENGINE OR PART (EITHER IN
            THE AIR OR ON THE GROUND) WHETHER OR NOT THE CLAIM MAY BE
            ATTRIBUTABLE TO ANY DEFECT IN THE AIRCRAFT, ANY ENGINE OR ANY PART
            OR TO ITS DESIGN, TESTING OR USE OR OTHERWISE, AND REGARDLESS OF
            WHEN THE SAME ARISES OR WHETHER IT ARISES OUT OF OR IS ATTRIBUTABLE
            TO ANY ACT OR OMISSION, NEGLIGENT OR OTHERWISE, OF ANY INDEMNITEE;

      (B)   WHICH ARISE OUT OF ANY ACT OR OMISSION WHICH INVALIDATES OR WHICH
            RENDERS VOIDABLE ANY OF THE INSURANCES; AND

      (C)   WHICH MAY AT ANY TIME BE SUFFERED OR INCURRED AS A CONSEQUENCE OF
            ANY DESIGN, ARTICLE OR MATERIAL IN THE AIRCRAFT, ANY ENGINE OR ANY

<PAGE>
 
            BREACH OF ANY OBLIGATION OF CONFIDENTIALITY OWED TO ANY PERSON;

      BUT EXCLUDING ANY CLAIM IN RELATION TO A PARTICULAR INDEMNITEE TO THE
      EXTENT THAT THAT CLAIM IS COVERED PURSUANT TO ANOTHER INDEMNITY PROVISION
      OF THIS AGREEMENT OR TO THE EXTENT IT ARISES SOLELY AS A RESULT OF THE
      GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THAT INDEMNITEE, LESSOR TAXES OR
      A LESSOR LIEN.

10.2  Duration: The indemnities contained in this agreement will continue in
      full force following the end of the Term notwithstanding any breach or
      repudiation by Lessor or Lessee of this Agreement or any termination of
      the lease of the Aircraft hereunder.

11.   EVENTS OF LOSS

11.1

(a)   Pre-delivery: If an Event of Loss occurs prior to delivery of the Aircraft
      to Lessee, Lessor will have the option, exercisable by giving Lessee
      notice in writing, to substitute an alternative aircraft of the same
      manufacture, model, value and utility as the Aircraft. If Lessor exercises
      such option, Lessee shall be obliged to lease such substitute aircraft
      pursuant to the terms and conditions of this Agreement and such substitute
      aircraft shall constitute the Aircraft for all purposes of this Agreement.
      Lessor shall provide Lessee with details of the substitute aircraft as
      soon as may be practicable after the occurrence of the Event of Loss. If
      Lessor advises Lessee that Lessor does not wish to exercise such option,
      this Agreement will immediately terminate and except as expressly stated
      in this Agreement neither party will have any further obligation or
      liability under this Agreement other than pursuant to Clause 16.9 except
      that Lessor will return the Deposit to Lessee; and

(b)   Post-delivery: If an Event of Loss occurs after delivery of the Aircraft
      to Lessee, Lessee will pay the Agreed Value to Lessor on or prior to the
      earlier of (i) 5 Business Days after the Event of Loss and (ii) the date
      of receipt of insurance proceeds in respect of that Event of Loss. Subject
      to the rights of any insurers and reinsurers or other third party, upon
      irrevocable payment in full to Lessor of that amount and all other amounts
      which may be or become payable to Lessor under this Agreement, Lessor will
      without recourse or warranty (except as to Lessor's Liens) and without
      further act, be deemed to have transferred to Lessee all of Lessor's
      rights to any Engines and Parts not installed when the Event of Loss
      occurred, all on an as-is where-is basis, and will at Lessee's expense,
      execute and deliver such bills of sale and other documents and instruments
      as Lessee may reasonably request to evidence (on the public record or
      otherwise) the transfer and the vesting of Lessor's rights in such Engines
      and Parts in Lessee, free and clear of all rights of Lessor and Lessor
      Liens.

                                       50
<PAGE>
 
(c)   Engine Event of Loss: From the Delivery Date upon an Engine Event of Loss,
      Lessee shall give Lessor prompt written notice thereof and shall, within
      45 days after such occurrence, convey to Lessor, as replacement for the
      Engine suffering such event, title to a Replacement Engine.  Each
      Replacement Engine shall be free of all Security Interests and shall be in
      as good an operating condition as the Engine being replaced, assuming the
      Engine being replaced was in the condition and repair required by the
      terms hereof immediately prior to the Engine Event of Loss. Upon full
      compliance by Lessee with the terms of this Clause 11.1(c), Lessor will
      transfer to Lessee title to the Engine which suffered the Engine Event of
      Loss.  Prior to or at the time of any such conveyance, Lessee, at its own
      expense, will promptly (i) furnish Lessor with a full warranty bill of
      sale, in form and substance reasonably satisfactory to Lessor, with
      respect to such Replacement Engine; (ii) cause a lease supplement (in form
      and substance satisfactory to Lessor) subjecting such Replacement Engine
      to this Agreement, to be duly executed by Lessee, and recorded pursuant to
      applicable Law; (iii) furnish Lessor with such evidence of title to such
      Replacement Engine as Lessor may reasonably request; (iv) furnish Lessor
      with an opinion of Lessee's counsel to the effect that title to such
      Replacement Engine has been duly conveyed to Lessor subject to this
      Agreement, free and clear of all Security Interests, and that such
      Replacement Engine is duly leased hereunder; (v) furnish a certificate
      signed by a duly authorized financial officer or executive of Lessee
      certifying that, upon consummation of such replacement, no Event of
      Default will have occurred or be continuing; (vi) furnish Lessor with such
      documents as Lessor may reasonably request in connection with the
      consummation of the transactions contemplated by this Clause 11.1(c), in
      each case in form and substance satisfactory to Lessor; and (vii) furnish
      such Financing Statements incorporating the Replacement Engine as may be
      requested by Lessor.  For all purposes hereof, each such Replacement
      Engine shall be deemed part of the property leased hereunder, shall be
      deemed an "Engine" as defined herein and shall be deemed part of the same
      Aircraft as was the Engine replaced thereof.  No Engine Event of Loss
      covered by this Clause 11.1(c) shall result in any reduction in Rent or
      affect Lessee's obligation to pay Engine Maintenance Reserves or the
      amount thereof to be paid by Lessee.

      Lessee shall indemnify each Indemnitee on an After-Tax Basis for any
      adverse tax consequence to such Indemnitee of the replacement of one or
      more Engines pursuant to this Clause 11.1.

11.2  Substitute Aircraft:

(a)   Without prejudice to the provisions of Clause 11.1 (b), if an Event of
      Loss occurs after delivery of the Aircraft to Lessee, Lessor will have the
      option, exercisable by giving Lessee notice in writing, to substitute an
      alternative aircraft (the "Substitute Aircraft") of the same manufacture
      and model as the Aircraft and having a value, utility and condition equal
      to or greater than the Aircraft as at the date of occurrence of the Event
      of Loss which Substitute Aircraft will be leased by Lessor to Lessee for
      the remainder of the Term pursuant to the terms and conditions of this
      Agreement.  If Lessor exercises such option, the Substitute Aircraft will
      constitute the Aircraft for all purposes of this Agreement in respect of
      facts and circumstances arising after the date of delivery thereof 

                                       51
<PAGE>
 
      to Lessee. Lessor shall provide Lessee with details of the Substitute
      Aircraft as soon as may be practicable after the occurrence of the Event
      of Loss;

(b)   Lessor will use all reasonable endeavors to deliver the Substitute
      Aircraft to Lessee as soon as may be practicable following the date of
      occurrence of the Event of Loss but not later than 3 months after such
      date; and

(c)   Lessee agrees to enter into such documentation as Lessor may require in
      order to reflect the leasing of the Substitute Aircraft as aforesaid
      including, without limitation, documentation in respect of the Insurances.

      Lessee shall indemnify each Indemnitee on an After-Tax Basis for any
      adverse tax consequence to such Indemnitee of the replacement of the
      Aircraft or Airframe pursuant to this Clause 11.2.

11.3  Requisition: During any requisition for use or hire of the Aircraft, any
      Engine or Part which does not constitute an Event of Loss:-

(a)   the Rent and other charges payable under this Agreement will not be
      suspended or abated either in whole or in part, and Lessee will not be
      released from any of its other obligations under the Agreement (other than
      operational obligations with which Lessee is unable to comply solely by
      virtue of the requisition); and

(b)   so long as no Default has occurred and is continuing, Lessee will be
      entitled to any hire paid by the requisitioning authority in respect of
      the Term. Lessee will, as soon as practicable after the end of any such
      requisition, cause the Aircraft to be put into the condition required by
      this Agreement. Lessor will be entitled to all compensation payable by the
      requisitioning authority in respect of any change in the structure, state
      or condition of the Aircraft arising during the period of requisition, and
      Lessor will apply such compensation in reimbursing Lessee for the cost of
      complying with its obligations under this Agreement in respect of any such
      change, but so that, if any Default has occurred and is continuing, Lessor
      may apply the compensation or hire in or towards settlement of any amounts
      owing by Lessee under this Agreement.

12.   RETURN OF AIRCRAFT

12.1  Return: On the Expiry Date or redelivery of the Aircraft pursuant to
      Clause 13.2 or termination of the leasing of the Aircraft under this
      Agreement Lessee will, unless an Event of Loss has occurred, at its
      expense, redeliver the Aircraft and Aircraft Documents to Lessor at the
      Redelivery Location or such other airport as is mutually acceptable to the
      parties hereto, in accordance with the procedures and in compliance with
      the conditions set forth in Schedule 3, free and clear of all Security
      Interests and Permitted Liens (other than Lessor Liens) and in a condition
      qualifying for immediate certification of airworthiness by the FAA or as
      otherwise agreed by Lessor and Lessee.

12.2  Final Inspection: Immediately prior to redelivery of the Aircraft, Lessee
      will make the Aircraft available to Lessor for inspection ("Final
      Inspection") in order to verify that the 

                                       52
<PAGE>
 
      condition of the Aircraft complies with this Agreement. The Final
      Inspection will be long enough to permit Lessor to:-

(a)   inspect the Aircraft Documents and uninstalled Parts;

(b)   inspect the Aircraft, provided that such inspection will not interfere
      with the scheduled operation of the Aircraft;

(c)   inspect the Engines, including without limitation (i) a borescope
      inspection of (A) the low pressure and high pressure compressors and (B)
      turbine and combustion areas, (ii) engine condition runs and (iii) review
      of Engine trend monitoring data and technical log reports covering the
      last ninety (90) days of operation; and

(d)   perform a complete borescope inspection of the APU; and

(e)   observe a 2 hour demonstration flight (with Lessor's representatives as
      on-board observers).

12.3  Non-Compliance: To the extent that, at the time of Final Inspection, the
      condition of the Aircraft does not comply with this Agreement, Lessee will
      at Lessor's option:-

(a)   immediately rectify the non-compliance and to the extent the non-
      compliance extends beyond the Expiry Date, the Term will be automatically
      extended and this Agreement will remain in force until the non-compliance
      has been rectified; or

(b)   redeliver the Aircraft to Lessor and indemnify Lessor on an After-Tax
      Basis, and provide to Lessor's satisfaction cash as security for that
      indemnity, against the cost of putting the Aircraft into the condition
      required by this Agreement.

12.4  Redelivery: Upon redelivery Lessee will provide to Lessor, upon Lessor's
      request, all documents necessary to export the Aircraft from the Habitual
      Base (including, without limitation, a valid and subsisting export license
      for the Aircraft) and required in relation to the deregistration of the
      Aircraft with the Air Authority.

12.5  Acknowledgment: Provided Lessee has complied with its obligations under
      this Agreement, following redelivery of the Aircraft by Lessee to Lessor
      at the Redelivery Location, Lessor will deliver to Lessee an
      acknowledgment confirming that Lessee has redelivered the Aircraft to
      Lessor in accordance with this Agreement.

12.6  Maintenance Program:

(a)   Prior to the Expiry Date and upon Lessor's request, Lessee will provide
      Lessor or its agent reasonable access to the Agreed Maintenance Program
      and the Aircraft Documents in order to facilitate the Aircraft's
      integration into any subsequent operator's fleet; and

                                       53
<PAGE>
 
(b)   Lessee will, if requested by Lessor to do so, upon return of the Aircraft
      deliver to Lessor a certified true current and complete copy of the Agreed
      Maintenance Program. Lessor agrees that it will not disclose the contents
      of the Agreed Maintenance Program to any person or entity except to the
      extent necessary to monitor Lessee's compliance with this Agreement and/or
      to bridge the maintenance program for the Aircraft from the Agreed
      Maintenance Program to another program after the Expiry Date.

12.7  Fuel: Upon redelivery of the Aircraft to Lessor, an adjustment will be
      made in respect of fuel on board on the Delivery Date and the Expiry Date
      at the price then prevailing at the Redelivery Location.

12.8  Automatic Extension of Term:  In the event of Lessee's failure to make the
      Aircraft available to Lessor for timely inspection pursuant to Clauses
      12.2 hereof, non-compliance of the condition of the Aircraft under Clause
      12.3 hereof or any other failure of Lessee which prevents timely
      Redelivery of the Aircraft to Lessor, the Term of this Agreement will be
      automatically extended and this Agreement will remain in force until such
      non-compliance has been rectified, with Lessee being obligated to pay Rent
      at a rate specified in Clause 5.3 plus 50 percent on a per diem basis with
      respect to the period of such extension.

13.   DEFAULT

13.1  Events:  Each of the following events will constitute an Event of Default
      and a repudiation (but not a termination) of this Agreement by Lessee
      (whether any such event or condition is voluntary or involuntary or occurs
      by operation of law or pursuant to or in compliance with any judgment,
      decree or order of any court or any order, rule or regulation of any
      Government Entity).  Lessee acknowledges that the occurrence of any Event
      of Default would represent a material default in the performance of its
      obligations under this Agreement:-

(a)   Non-payment: Lessee fails to make any payment under this Agreement or any
      of the Operative Documents on the due date; or

(b)   Insurance: Lessee fails to comply with any provision of Clause 9 or any

      terminated or notice of cancellation is given in respect of any such
      insurance; or

(c)   Breach: Lessee fails to comply with any other provision of this Agreement
      or any of the Operative Documents and, if such failure is in the
      reasonable opinion of Lessor capable of remedy, the failure continues for
      5 days after notice from Lessor to Lessee; or

(d)   Representation: any representation or warranty made (or deemed to be
      repeated) by Lessee in or pursuant to this Agreement or in any document or
      certificate or statement is or proves to have been incorrect in any
      material respect when made or deemed to be repeated; or

                                       54
<PAGE>
 
(e)   Cross Default:

            aggregate, shall be rendered against Lessee and the same shall
            remain undischarged for a period of ninety (90) days during which
            execution thereof shall not be effectively stayed by agreement of
            the parties involved, stayed by court order or adequately bonded; or

      (ii)  attachments or other Security Interests shall be issued or entered
            against substantially all of the property of Lessee and shall remain
            undischarged or unbonded for ninety (90) days except for Security
            Interests created in connection with monies borrowed or obligations
            agreed to by Lessee in the ordinary course of its business; or

      (iii) Lessee shall default in the payment of any sum which by itself is
            in excess of $100,000 or any sums which in aggregate exceed $250,000
            notwithstanding that any particular individual sum thereof does not
            exceed $100,000 of any one or more obligations for the payment of
            borrowed money, for the deferred purchase price of property or for
            the payment of rent or hire under any lease of aircraft when the
            same becomes due if such nonpayment results in or would permit an
            acceleration of such indebtedness, or Lessee shall default in the
            performance of any other term, agreement, or condition contained in
            any agreement or instrument under or by which any such obligation is
            created, evidenced or secured, if the effect of such default is to
            cause or permit such obligation to become due prior to its stated
            maturity; or

      (iv)  any event of default or termination event, howsoever described,
            occurs under the Other Agreements; or

            corporations, or provides for an agreement, composition, extension
            or adjustment with its creditors, or any corporate action

            by Lessor (or such other location as Lessor may require) (the

            liability accruing to Lessor for or by reason of such entry or
            taking of possession whether for the restoration of damage to
            property, or otherwise, caused by such entry or taking, except
            damages caused by gross negligence or willful misconduct; and Lessor
            is hereby irrevocably, by way of security for Lessee's obligations
            under this Agreement, appointed attorney for Lessee in causing the
            redelivery or in directing the pilots of Lessee or other pilots to
            fly the Aircraft to that airport 

                                       58
<PAGE>
 
            and will have all the powers and authorizations necessary for taking
            that action; or

      (ii)  by serving notice require Lessee to redeliver the Aircraft to Lessor
            at a point within the continental United States designated by
            Lessor; and/or

(e)   sell at private or public sale, as Lessor may determine, or hold, use,
      operate or lease to others the Aircraft as Lessor in its sole discretion
      may determine, all free and clear of any rights of Lessee; and/or

(f)   whether or not Lessor shall have exercised, or shall thereafter at any
      time exercise, any of its rights under paragraph (a), paragraph (b),
      paragraph (c), paragraph (d), or paragraph (e) of this Clause 13.2,
      Lessor, by 30 days written notice to Lessee specifying a payment date, may
      demand that Lessee pay to Lessor, and Lessee shall pay to Lessor, on the
      payment date specified in such notice, as liquidated damages for loss of
      bargain and not as a penalty (in lieu of the Rent due for the period
      commencing after the date specified for payment in such notice), any
      unpaid Rent for the Aircraft and other amounts owing under this Agreement
      (prorated in the case of Rent on a daily basis) to and including the
      payment date specified in such notice, plus the amount, if any, by which
      the aggregate Rent for the remainder of the Term (determined without
      reference to any right of Lessor to terminate the leasing of the Aircraft,
      whether or not such right is exercised), discounted periodically (equal to
      installment frequency) to present worth at the interest rate of 4 percent
      (4%) per annum, exceeds the fair market rental value (determined pursuant
      to the Appraisal Procedure) of the Aircraft for the remainder of the Term,
      after discounting such fair market rental value periodically (equal to
      installment frequency) to present worth as of the payment date specified
      in such notice at the interest rate of 4 percent (4%) per annum; and/or

(g)   In the event that Lessor, pursuant to Clause 13.2(e) above, shall have
      relet the Aircraft under a lease which extends at least to the date upon
      which the Term for the Aircraft would have expired but for Lessee's
      default, Lessor, in lieu of exercising its rights under Clause 13.2(f)
      above with respect to the Aircraft, may, if it shall so elect, demand that
      Lessee pay Lessor, and Lessee shall pay Lessor, as liquidated damages for
      loss of bargain and not as a penalty (in lieu of the Rent for the Aircraft
      due after the time of reletting) any unpaid Rent for the Aircraft due up
      to the date of reletting and any other amounts owing under this Agreement,
      plus the amount, if any, by which the aggregate Rent for the Aircraft,
      which would otherwise have become due over the remainder of the Term
      (determined without reference to any right of Lessor to terminate the
      leasing of the Aircraft, whether or not such right is exercised),
      discounted periodically (equal to installment frequency) to present worth
      as of the date of reletting at the interest rate of 4 percent (4%) per
      annum, exceeds the aggregate basic rental payments to become due under the
      reletting from the date of such reletting to the date upon which the Term
      for the Aircraft would have expired but for Lessee's default, discounted
      periodically (equal to installment frequency) to present worth as of the
      date of the reletting at the interest rate of 4 percent (4%) per annum;
      and/or

                                       59
<PAGE>
 
(h)   in lieu of the remedies set forth in paragraphs (a), (c), (d), (e), (f),
      and (g) of this Clause 13.2, by 30 days written notice to Lessee
      specifying a payment date, Lessor may demand that Lessee pay to Lessor,
      and Lessee shall pay to Lessor on the payment date specified in such
      notice as liquidated damages for loss of bargain and not as a penalty (in
      lieu of the Rent due for the period commencing after the date specified
      for payment in such notice), any unpaid Rent for the Aircraft and other
      amounts payable under this Agreement (prorated in the case of Rent on a
      daily basis) to and including the payment date specified in such notice,
      plus an amount equaling the aggregate Rent for the remainder of the Term,
      discounted periodically (equal to installment frequency) to present worth
      at the interest rate of 4 per cent (4%) per annum;

(i)   draw upon the Deposits or the Maintenance Reserves furnished under this
      Agreement or the Other Agreements to which Lessor or any affiliate or
      associate thereof (which for clarification does not include GPA Group PLC,
      Airplane Holdings Limited or any affiliate or associate, successor thereto
      or assignee thereof ) is a party and apply such amounts to amounts owing
      to Lessor hereunder.

      Lessee, for itself and for its successors and assigns, hereby agrees that,
      to the extent now or hereafter permitted by applicable Law,
      notwithstanding any provision of the Federal Bankruptcy Code as amended
      from time to time, the title of Lessor to the Aircraft and any right of
      Lessor to take possession of the Aircraft in compliance with the
      provisions of this Agreement, in each case, upon the occurrence and
      continuance of an Event of Default, shall not be affected by the
      provisions of the Federal Bankruptcy Code, as amended from time to time.

      In addition to the foregoing, Lessee shall be liable for any and all
      unpaid Rent and other amounts payable under this Agreement during or after
      the exercise of any of the aforementioned remedies, together with interest
      on such unpaid amounts at the Interest Rate set forth in Letter Agreement
      No. 1, and until satisfaction of all of Lessee's obligations to Lessor
      hereunder and (on an After-Tax Basis) for all reasonable legal fees and
      other reasonable costs and expenses incurred by Lessor by reason of the
      occurrence of any Event of Default or the exercise of Lessor's remedies
      with respect thereto, including all costs and expenses incurred in
      connection with the return of the Aircraft in accordance with the terms of
      Clause 12 hereof or in placing the Aircraft in the condition and with
      airworthiness certification as required by such Clause.

      In effecting any repossession, Lessor and its representatives and agents,
      to the extent permitted by Law, shall: (i) have the right to enter upon
      any premises where it reasonably believes the Aircraft, the Airframe, an
      Engine or Part to be located; (ii) not be liable, in conversion or
      otherwise, for the taking of any personal property of Lessee which is in
      or attached to the Aircraft, the Airframe, an Engine or Part which is
      repossessed; provided, however, that Lessor shall return to Lessee all
      personal property of Lessee or its passengers which was on the Aircraft at
      the time Lessor re-takes possession of the Aircraft; (iii) not be liable
      or responsible, in any manner, for any inadvertent damage or injury to any
      of Lessee's property in repossessing and holding the Aircraft, the
      Airframe, an Engine or Part, except for that caused by or in connection

                                       60
<PAGE>
 
      with Lessor's gross negligence or willful acts; (iv) have the right to
      maintain possession of and dispose of the Aircraft, the Airframe, an
      Engine or Part on any premises owned by Lessee or under Lessee's control;
      and (v) have the right to obtain a key to any premises at which the
      Aircraft, the Airframe, an Engine or Part may be located from the landlord
      or owner thereof.

      If reasonably required by Lessor, Lessee, at its sole expense, shall
      assemble and make the Aircraft, the Airframe, an Engine or Part available
      at a place designated by Lessor in accordance with Clause 12 hereof.
      Lessee hereby agrees that, in the event of the return to or repossession
      by Lessor of the Aircraft, the Airframe, an Engine or Part, any rights in
      any warranty (express or implied) previously assigned to Lessee or
      otherwise held by Lessee shall without further act, notice or writing be
      assigned or reassigned to Lessor, if assignable.  Lessee shall be liable
      to Lessor on an After-Tax Basis for all reasonable expenses,
      disbursements, costs and fees incurred in (i) repossessing, storing,
      preserving, shipping, maintaining, repairing and refurbishing the
      Aircraft, the Airframe, an Engine or Part to the condition required by
      Clause 12 hereof and (ii) preparing the Aircraft, the Airframe, an Engine
      or Part for sale or lease, advertising the sale or lease of the Aircraft,
      the Airframe, an  Engine or Part and selling or releasing the Aircraft,
      the Airframe, an Engine or Part.  Lessor is hereby authorized and
      instructed, at its option, to make reasonable expenditures which Lessor
      considers advisable to repair and restore the Aircraft, the Airframe, an
      Engine or Part to the condition required by Clause 12 hereof, all at
      Lessee's sole expense.

      At any public sale of the Aircraft, the Airframe, an Engine or Part
      pursuant to this Clause, Lessor may bid for and purchase such property and
      Lessee agrees that the amounts paid therefor shall be used in the
      computation contemplated herein.

      With the exception that the remedy in Clause 13.2(g) can be elected only
      if the remedy in Clause 13.2(f) is not elected and the remedy in Clause
      13.2(h) can be elected only in lieu of all other remedies save the
      remedies in Clauses 13.2(b) and 13.2(i), no remedy referred to in this
      Clause 13 is intended to be exclusive, but, to the extent permissible
      hereunder or under applicable Law, each shall be cumulative and in
      addition to any other remedy referred to above or otherwise available to
      Lessor at Law or in equity; and the exercise or beginning of exercise by
      Lessor of any one or more of such remedies shall not preclude the
      simultaneous or later exercise by Lessor of any or all of such other
      remedies; provided, however, that nothing in this Clause 13 shall be
      construed to permit Lessor to obtain a duplicate recovery of any element
      of damages to which Lessor is entitled.  No express or implied waiver by
      Lessor of any Default or Event of Default shall in any way be, or be
      construed to be, a waiver of any future or subsequent Default.

13.3  Deregistration: If an Event of Default occurs, Lessor may sell or
      otherwise deal with the Aircraft free and clear of any leasehold or other
      interest of Lessee as if this Agreement had never been made and Lessee
      will at the request of Lessor take all steps necessary to effect (if
      applicable) deregistration of the Aircraft and its export from the country
      where the Aircraft is for the time being situated and any other steps
      necessary to enable the Aircraft to be redelivered to Lessor in accordance
      with this Agreement 

                                       61
<PAGE>
 
      including without limitation execution and filing of a certificate or
      other instrument of lease termination with the Air Authority and; Lessee
      hereby irrevocably and by way of security for its obligations under this
      Agreement appoints (which appointment is coupled with an interest) Lessor
      as its attorney to execute and deliver any documentation and to do any act
      or thing required in connection with the foregoing.

14.   ASSIGNMENT

14.1  Lessee's Assignment: LESSEE WILL NOT ASSIGN, TRANSFER (VOLUNTARILY OR
      INVOLUNTARILY BY OPERATION OF LAW OR OTHERWISE) OR CREATE OR PERMIT TO
      EXIST ANY SECURITY INTEREST OVER, ANY OF ITS RIGHTS UNDER THIS AGREEMENT.

14.2  Lessor's Assignment: Lessor may assign or transfer all or any of its
      rights under this Agreement and in the Aircraft.  In the case of an
      assignment other than by way of security, Lessor will be released from and
      will have no further obligation under this Agreement following the
      assignment of all its rights under this Agreement and the assumption by
      the assignee or transferee of all of Lessor's obligations under this
      Agreement.  Notwithstanding any such assignment, Lessor will remain
      entitled to the benefit of each indemnity and the liability insurances
      effected under this Agreement. Lessee will comply with all reasonable
      requests of Lessor, its successors and assigns in respect of any such
      assignment. Lessor will promptly notify Lessee of any assignment.

14.3  Transfer: If Lessor desires to effect any assignment or transfer of its
      rights and obligations under this Agreement, Lessee agrees to cooperate
      and take all such steps as Lessor may reasonably request to give the
      transferee the benefit of this Agreement and to acknowledge the release of
      Lessor from its obligations hereunder as of the time of such assignment or
      transfer.

15.   ILLEGALITY

      If it is or becomes unlawful in any jurisdiction for Lessor to give effect
      to any of its obligations as contemplated by this Agreement or to continue
      this Agreement, Lessor may by notice in writing to Lessee terminate the
      leasing of the Aircraft under this Agreement and Lessee will forthwith
      redeliver the Aircraft to Lessor in accordance with Clause 12. Without
      prejudice to the foregoing Lessor will consult in good faith with Lessee
      as to any steps which may be taken to restructure the transaction to avoid
      that unlawfulness but will be under no obligation to take any such steps.

16.   MISCELLANEOUS

16.1  Waivers, Remedies Cumulative: The rights of Lessor under this Agreement:-

      (i)   may be exercised as often as necessary;

      (ii)  are cumulative and not exclusive of its rights under any Law; and

                                       62
<PAGE>
 
      (iii) may be waived only in writing and specifically.

      Delay in exercising or non-exercise of any such right will not constitute
      a waiver of that right.

16.2  Delegation: Lessor may delegate to any person or persons all or any of the
      trusts, powers or discretions vested in it by these presents and any such
      delegation may be made upon such terms and conditions and subject to such
      regulations (including power to sub-delegate) as Lessor in its absolute
      discretion thinks fit.

16.3  Certificates: Save where expressly provided in this Agreement, any
      certificate or determination by Lessor as to any rate of interest or as to
      any other amount payable under this Agreement will, in the absence of
      manifest error, be conclusive and binding on Lessee.

16.4  Appropriation: If any sum paid or recovered in respect of the liabilities
      of Lessee under this Agreement is less than the amount then due, Lessor
      may apply that sum to amounts due under this Agreement in such proportions
      and order and generally in such manner as Lessor may determine at its sole
      discretion.

16.5  Currency:

      Lessee acknowledges that the specification of Dollars in this Agreement is
      of the essence and that Dollars shall be the currency of account in any
      and all events.  Lessee waives any right it may have in any jurisdiction
      to pay any amount under this Agreement in a currency other than Dollars.

16.6  Set-off: Lessor may set off any matured obligation owed by Lessee under
      this Agreement or under any other agreement between Lessor or any
      affiliate or associate of Lessor (which for clarification does not include
      GPA Group plc, Airplanes Holdings Limited or any affiliate or associate,
      successor thereto or assignee thereof) and Lessee against any obligation
      (whether or not matured) owed by Lessor to Lessee, regardless of the place
      of payment or currency.  If the obligations are in different currencies,
      Lessor may convert either obligation at the market rate of exchange
      available in New York or at its option London for the purpose of the set-
      off.  If an obligation is unascertained or unliquidated, Lessor may in
      good faith estimate that obligation and set off in respect of the
      estimate, subject to the relevant party accounting to the other when the
      obligation is ascertained or liquidated.  Lessor will not be obliged to
      pay any amounts to Lessee under this Agreement so long as any sums which
      are then due from Lessee under this Agreement or under any other agreement
      between Lessor or any affiliate or associate of Lessor (which for
      clarification does not include GPA Group plc, Airplanes Holdings Limited
      or any affiliate or associate, successor thereto or assignee thereof) and
      Lessee remain unpaid and any such amounts which would otherwise be due
      will fall due only if and when Lessee has paid all such sums except to the
      extent Lessor otherwise agrees or sets off such amounts against such
      payment pursuant to the foregoing.

                                       63

16.7  Severability: If a provision of this Agreement is or becomes illegal,
      invalid or unenforceable in any jurisdiction, that will not affect:-

(a)   the legality, validity or enforceability in that jurisdiction of any other
      provision of this Agreement; or

(b)   the legality, validity or enforceability in any other jurisdiction of that
      or any other provision of this Agreement.

16.8  Remedy: If Lessee fails to comply with any provision of this Agreement,
      Lessor may, without being in any way obliged to do so or responsible for
      so doing and without prejudice to the ability of Lessor to treat the non-
      compliance as a Default or an Event of Default, effect compliance on
      behalf of Lessee, whereupon Lessee shall become liable to pay immediately
      any sums expended by Lessor together with all costs and expenses
      (including legal costs) in connection therewith.

16.9  Expenses: Whether or not the Aircraft is delivered to Lessee pursuant to
      this Agreement, Lessee will pay to Lessor on an After-Tax Basis on
      demand:-

      (a)   all costs associated with perfecting Lessor's rights in the Aircraft
            and/or this Agreement in the State of Registration, the Habitual
            Base of the Aircraft (and other states as appropriate given the
            operation of the Aircraft), including (but not limited to) the
            provision of legal opinions, tax advice, stamp duties, translations
            and registrations, whether required by Lessor or Lessee.

      (b)   all expenses (including legal, professional, and out-of-pocket
            expenses) incurred or payable by Lessor related to any amendment to
            or extension of or other documentation in connection with, or the
            granting of any waiver or consent under this Agreement requested by
            Lessee or the monitoring of compliance by Lessee with this
            Agreement; and

      (c)   all expenses (including legal, survey and other costs) payable or
            incurred by Lessor in contemplation of, or otherwise in connection
            with, the enforcement of or preservation of any of Lessor's or
            Owner's rights under this Agreement, or in respect of the
            repossession of the Aircraft.

      All expenses payable pursuant to this Clause 16.9 will be paid in the

18.   SECTION 1110

      Lessee acknowledges that Lessor would not have entered into this Agreement
      unless it had available to it the benefits of a lessor under Section 1110
      of Title 11 of the United States Code.  Lessee covenants and agrees with
      Lessor that to better ensure the availability of such benefits, Lessee
      shall support any motion, petition or application filed by Lessor with any
      bankruptcy court having jurisdiction over Lessee, whereby Lessor seeks
      recovery of possession of the Aircraft under said Section 1110 and shall
      not in any way oppose such action by Lessor unless Lessee shall have
      complied with the requirements of said Section 1110 to be fulfilled in
      order to entitle Lessee to continued use and possession of the Aircraft
      hereunder.  In the event said Section 1110 is amended, or if it is
      repealed and another statute is enacted in lieu thereof, Lessor and Lessee
      agree to amend this Agreement and take such other action not inconsistent
      with this Agreement as Lessor reasonably deems necessary so as to afford
      to Lessor the rights and benefits as such amended or substituted statute
      confers upon owners and lessors of aircraft similarly situated to Lessor.

19.   USURY LAWS:  The parties intend to contract in strict compliance with the
      usury Laws of the States of California and Colorado and, to the extent
      applicable, the United States of America.  Notwithstanding anything to the
      contrary in the Operative Documents, Lessee will not be obligated to pay
      any interest in excess of the maximum non-usurious interest rate, as in
      effect from time to time, which may by applicable Law be charged,
      contracted for, reserved, received or collected by Lessor in connection
      with the Operative Documents.  During any period of time in which the
      then-applicable highest lawful rate is lower than the rate specified in
      Clauses 5.11 or 13.2, interest will accrue and be payable at such highest
      lawful rate; however, if at later times such highest lawful rate is
      greater than the rate specified in Clauses 5.11 or 13.2, then Lessee will
      pay interest at the highest lawful rate until the aggregate amount of
      interest paid by Lessee equals the amount of interest that would have been
      payable in accordance with the interest rate specified in Clauses 5.11 or
      13.2.

20.   MODIFICATION OR REVISION:

      Neither this Agreement nor any term of this Agreement may be modified,
      rescinded, changed waived, discharged or terminated except by a writing
      signed by the party to be charged.  Lessor and Lessee acknowledge their
      agreement to the provision of this Clause 20 by their initials below: -

            The Insurances required to be maintained are as follows:-

(a)   HULL ALL RISKS of Loss or Damage whilst flying and on the ground with
      respect to the Aircraft on an "agreed value basis" for the Agreed Value
      and with a deductible not exceeding the Deductible Amount set forth in
      Letter Agreement No. 1, or such other amount agreed by Lessor from time to
      time;

(b)   HULL WAR AND ALLIED PERILS, being such risks excluded from the Hull All
      Risks Policy to the fullest extent available from the leading
      international insurance markets including confiscation and requisition by
      the State of Registration for the Agreed Value, however, when the Aircraft
      is being operated solely in or over the United States of America and/or
      Canada, coverage may be limited to such perils as are customarily insured
      by comparable airlines, operating similar equipment in similar
      circumstances;

(c)   ALL RISKS (INCLUDING WAR AND ALLIED RISK except when on the ground or in
      transit other than by air) property insurance on all Engines and Parts
      when not installed on the Aircraft on an "agreed value" basis for their
      full replacement value and including engine test and running risks;

(d)   AIRCRAFT THIRD PARTY, PROPERTY DAMAGE, PASSENGER, BAGGAGE, CARGO AND MAIL
      AND AIRLINE GENERAL THIRD PARTY (INCLUDING PRODUCTS) LEGAL LIABILITY for a
      Combined Single Limit (Bodily Injury/Property Damage) of an amount not
      less than the Minimum Liability Coverage for the time being any one
      occurrence (but in respect of products and personal injury liability this
      limit may be an aggregate limit for any and all losses occurring during
      the currency of the policy). War and Allied Risks are also to be covered
      under the Policy in  line with prudent market practice for comparable
      airlines, operating similar equipment in similar circumstances;

(e)   All required hull and spares insurance (as specified above), so far as it
      relates to the Aircraft will: -

      (i)   name Lessor and its successors and assigns as additional assureds
            for their respective rights and interests, warranted, each as to
            itself only, no operational interest;

      (ii)  provide that any loss will be settled jointly with Lessor and Lessee
            and will be payable in Dollars to Lessor except where the loss does
            not exceed the Damage Notification Threshold, and Lessor has not
            notified the insurers to the contrary, in which case the loss will
            be settled with and paid to Lessee;

                                      4-1
<PAGE>
 
      (iii) if separate Hull "all risks" and "war risks" insurances are
            arranged, include a 50/50 provision in accordance with market
            practice (AVS. 103 is the current market language);

      (iv)  confirm that the insurers are not entitled to replace the Aircraft
            in the event of an insured Event of Loss;

      (v)   confirm that the insurers will not obtain a valid discharge of the
            obligations under the Insurances by payment to the broker,
            notwithstanding market practice to the contrary;

(f)   All required liability insurances (specified above) will:-

      (i)   include Lessor, GECASI, GECASL and their respective successors and
            assigns and their respective shareholders, subsidiaries, directors,
            officers, agents, employees and indemnitees as additional insureds
            for their respective rights and interests, warranted, each as to
            itself only, no operational interest;

      (ii)  include a Severability of Interest Clause which provides that the
            insurance, except for the limit of liability, will operate to give
            each assured the same protection as if there was a separate policy
            issued to each assured;

      (iii) contain a provision confirming that the policy is primary without
            right of contribution and the liability of the insurers will not be
            affected by any other insurance of which Lessor or Lessee have the
            benefit so as to reduce the amount payable to the additional
            insureds under such policies;

(g)  All Insurances will:-

      (i)   be in accordance with normal industry practice of persons operating
            similar aircraft in similar circumstances;

      (ii)  provide cover denominated in Dollars and any other currencies which
            Lessor may reasonably require in relation to liability insurance;

            assureds the Insurances will not be invalidated by any act or
            omission by Lessee, or any other person other than the respective
            additional assured seeking protection and shall insure the interests
            of each of the additional assureds regardless of any breach or
            violation by Lessee, or any other person other than the

                                      4-2
<PAGE>
 
            respective additional assured seeking protection of any warranty,
            declaration or condition, contained in such Insurances;

      (vi)  provide that the insurers will hold harmless and waive any rights of
            recourse and/or subrogation against the additional assureds,
            including GECASI and GECASL or to be subrogated to any rights of
            Lessor against Lessee;

      (vii) provide that the additional assureds will have no obligation or
            responsibility for the payment of any premiums due (but reserve the
            right to pay the same should any of them elect so to do) and that
            the insurers will not exercise any right of set-off or counter-claim
            in respect of any premium due against the respective interests of
            the additional assureds other than outstanding premiums relating to

portion thereof) of the Lease Term the Aircraft operated more cycles than the
maximum number of cycles which would result from an average hour/cycle ratio of
2 to 1, LESSEE will pay LESSOR as additional Rent US$ 75 for each cycle the
Aircraft actually operated during such calendar year (or portion thereof) in
excess of the number of cycles which result from an average hour/cycle ratio of
2 to  1.  A calculation will be made as of December 31 of each year and such
additional Rent will be due and payable by LESSEE on the date on which the next
Reserve payment is due (in accordance with Article 5.4.3) following such
hour/cycle calculation period.

      Example: If the Aircraft operated 2,000 hours in a calendar year, it would
      have 1,000 cycles resulting from an average hour/cycle ratio of to . If in
      fact the Aircraft operated * cycles in such calendar year, the Aircraft
      operated * excess cycles in such calendar year and LESSEE will pay LESSOR

deduction or withholding whether in respect of set-off, counterclaim, duties, or
Taxes (as defined in Article 16) imposed in the State of Registration or any

           remedies to pursue in a court of law any claim it may have against
           LESSOR or any other Person.

5.12       LESSOR Performance of LESSEE Obligation.   If LESSEE fails to make

LESSEE will repay such amount to LESSOR together with Default Interest. Such
payment to LESSOR will constitute additional Rent payable by LESSEE to LESSOR
hereunder. Any payment, performance or compliance by LESSOR of a LESSEE
obligation hereunder will not affect the occurrence or continuance of a Default
or Event of Default, as the case may be.

           ----------------------------------------                             
other payments contained herein are in consideration of LESSEE's waiver of
warranties and indemnities set forth in Articles 8 and 17, respectively, and the
other provisions of this Lease.

     ARTICLE 6       LESSEE INVOLVEMENT WITH AIRCRAFT MANUFACTURER
     ---------       ---------------------------------------------


6.1        LESSEE Selection of Aircraft.  LESSEE ACKNOWLEDGES THAT THE
           ----------------------------                               
DESCRIPTION OF THE AIRCRAFT SET FORTH IN THIS LEASE IS BASED UPON INFORMATION
SUPPLIED BY MANUFACTURER.  LESSEE COVENANTS TO LESSOR THAT LESSEE HAS USED ITS
OWN JUDGMENT IN SELECTING THE AIRCRAFT AND HAS DONE SO BASED ON ITS SIZE, DESIGN
AND TYPE.  LESSEE ACKNOWLEDGES THAT LESSOR IS NOT A MANUFACTURER OF THE AIRCRAFT
OR DEALER IN THE AIRCRAFT.

6.2        Agency Agreement between LESSEE and LESSOR.  Certain obligations
           ------------------------------------------                      
remain to be performed by LESSOR in connection with the manufacture, fabrication
and completion of the Aircraft by Manufacturer which will be performed by LESSEE
(as provided in the Agency Agreement). LESSEE will act as LESSOR's agent with
respect to some of these matters pursuant to the terms of an Agency Agreement to
be entered into between LESSEE and LESSOR in the form set forth in Exhibit B.
LESSEE will not be responsible to LESSOR as a result of serving as LESSOR's
agent unless such liability results from LESSEE's negligence.

6.3        Procurement of BFE.  LESSEE's and LESSOR's technical representatives
           ------------------                                                  
will meet and agree upon which of LESSEE or LESSOR will provide specific items
of BFE. Such BFE will then be provided to Manufacturer by LESSEE or LESSOR, as
applicable, within the timeframes required by Manufacturer.

6.4        Assignment of Training.  LESSOR hereby assigns to LESSEE all rights
           ----------------------                                             
to training to which LESSOR is entitled as a result of LESSOR's purchase of the
Aircraft and lease of the Aircraft to LESSEE. If LESSEE fails to take Delivery
of the Aircraft when tendered in accordance with Article 6.7, LESSEE will
immediately pay to LESSOR an amount equal to the Dollar value of such training
based on what the training would have cost LESSEE had LESSEE purchased such
training directly from Manufacturer.

6.5        LESSEE Inspection of Aircraft.  During the course of final assembly
           -----------------------------                                      
of the Aircraft, and at Delivery, LESSEE will have its own representative
present to supervise and inspect the Aircraft and to ensure its conformity with
LESSEE's needs and the terms of this Lease. LESSEE will have ground inspection
and acceptance flight rights with respect to the Aircraft. LESSEE acknowledges
that, as between it and LESSOR, in accepting the Aircraft it is relying on its
own inspection and knowledge of the

                                      22
<PAGE>
 
Aircraft in determining whether it meets the requirements of this Lease.

6.6        Aircraft at Delivery.  At Delivery, the Aircraft will be as set forth
           --------------------                                                 
in Exhibit A, as such description may be modified by any change requests agreed
to among LESSEE, LESSOR and Manufacturer (which will be reflected in
amendment(s) to this Lease). In the event of any discrepancies, LESSEE and
LESSOR will cooperate in good faith with one another and with Manufacturer and
Engine manufacturer, as applicable, in order to arrive at a mutually acceptable
resolution of any such discrepancies. The Aircraft will be accepted by LESSOR
from Manufacturer simultaneously with LESSEE's acceptance of the Aircraft from
LESSOR pursuant to this Lease. Thus, when LESSEE confirms to LESSOR that the
Aircraft meets such condition and specification, LESSOR will accept the Aircraft
from Manufacturer.

6.7        Delivery of the Aircraft to LESSEE.  Subject to LESSEE having
           ----------------------------------                           
performed all of the conditions precedent to Delivery set forth herein,
immediately following delivery of the Aircraft from Manufacturer to LESSOR,
LESSOR will deliver the Aircraft to LESSEE at the Delivery Location. Provided
that the Aircraft is in the condition required by Article 6.6, upon the tender
of the Aircraft by LESSOR to LESSEE, LESSEE will accept the Aircraft and the
date of tender by LESSOR to LESSEE will be deemed to be the Delivery Date for
all purposes under this Lease, including but not limited to the commencement of
LESSEE's obligation to pay Rent hereunder.

6.8        LESSEE Acceptance of Aircraft.  So long as the Aircraft is in the
           -----------------------------                                    
condition specified in Article 6.6, LESSEE will accept the Aircraft when
tendered for delivery by LESSOR. If LESSEE fails to (i) comply with its
obligations set forth in Article 6.2, (ii) comply with the conditions contained
in Articles 7.1 and 7.2 so as to allow Delivery to take place immediately
following delivery of the Aircraft by Manufacturer to LESSOR or (iii) take
delivery of the Aircraft when properly tendered for delivery by LESSOR in the
condition required hereunder, LESSEE will indemnify LESSOR for all costs and
expenses incurred by LESSOR as a result thereof including (but without
limitation) any payments other than the purchase price which LESSOR becomes
obliged to make to Manufacturer.

                (2) No Default has occurred and is continuing or will result

LESSEE AGREES NOT TO LOOK TO LESSOR FOR DAMAGES OR RELIEF ARISING OUT OF THE
FAILURE OF THE AIRCRAFT TO CONFORM TO SUCH DESCRIPTION.

its own cost and expense will do all such things and execute such documents as
may be required for this purpose.

     ARTICLE 10      OPERATION OF AIRCRAFT
     ----------      ---------------------


10.1       Costs of Operation.  LESSEE will pay all costs incurred in the
           ------------------                                            
operation of the Aircraft during the Lease Term, for profit or otherwise,

maintenance, insurance, storage, landing and navigation fees, airport charges,
passenger service and any and all other expenses of any kind or nature, directly
or indirectly, in connection with or related to the use, movement and operation

accordance with the applicable regulations of IATA. LESSEE will not employ,
suffer or cause the Aircraft to be used in any business which is forbidden by
Law or in any manner which may render it liable to condemnation, destruction,
seizure, or confiscation by any authority. LESSEE will not permit the Aircraft
to fly to any airport or country if so doing would cause LESSOR to be in
violation of any U.S. Law.

10.3       Training.  LESSEE will not use the Aircraft for testing or for

training of flight crewmembers other than LESSEE crewmembers and will not use
the Aircraft for training any more than it utilizes for training the other
aircraft in its fleet.

10.4       No Violation of Insurance Policies.   LESSEE will not use or permit
           ----------------------------------                                 
the Aircraft to be used in any manner or for any purpose which is not covered by
the insurance policies LESSEE is required to carry and maintain as set forth in
this Lease. LESSEE will not carry any goods of any description excepted or
exempted from such policies or do any other act or permit to be done anything
which could reasonably be expected to invalidate or limit any such insurance
policy.

     ARTICLE 11      SUBLEASES
     ----------      ---------


11.1       No Sublease without LESSOR Consent.  LESSEE WILL NOT SUBLEASE OR PART
           ----------------------------------                                   
WITH POSSESSION OF THE AIRCRAFT (EXCEPT FOR MAINTENANCE AND REPAIR) AT ANY TIME
WITHOUT THE PRIOR WRITTEN CONSENT OF LESSOR (NOT TO BE UNREASONABLY WITHHELD)
EXCEPT FOR A SUBLEASE TO AN OPERATOR PRE-APPROVED IN ARTICLE 11.1.1 BELOW,  AND
IN ACCORDANCE WITH SUCH REQUIREMENTS AS MAY FROM TIME TO TIME BE AGREED IN
WRITING BETWEEN LESSOR AND LESSEE.  The wet leasing of the Aircraft during the
Lease Term (in which LESSEE and its crews retain operational control of the
Aircraft) will not be considered a sublease of the Aircraft.

11.1.1     LESSEE may sublease the Aircraft without LESSOR's prior consent to an
           operator based in the U.S. which is then currently a lessee of
           LESSOR, provided said operator is not then in default under the
           aircraft lease agreement between such operator and LESSOR. Any such
           sublease will be subject to the provisions of this Article 11,
           except that such sublease would not be subject to the subleasing
           proposal fee referred to in Article 11.2 below.

11.2       Subleasing Proposal Fee.  Any subleasing proposals submitted to
           -----------------------                                        
LESSOR (other than a proposed sublease (x) to a sublessee which is pre-approved
pursuant to Article 11.1.1 or (y) to the first three proposed sublessees outside
the U.S. which are then current lessees of LESSOR, provided said operators are
not then in default under the aircraft lease agreement between such operator and
LESSOR) will be subject to a processing fee of  *  U.S. Dollars (US$  *  ),
payable on demand (whether the sublease is approved or not).  In addition,
LESSEE will indemnify LESSOR on demand for all reasonable out-of-pocket expenses
(including legal fees) incurred in connection with its assessment of the
proposal or its implementation.

with this Lease protecting LESSOR's title to the Aircraft, providing appropriate
LESSOR indemnities, regarding the maintenance and repair standards for the
Aircraft, concerning the insurances which will be carried by the sublessee and
the circumstances which constitute a Total Loss of the Aircraft. Any such
sublease will be subject and subordinate to this Lease. In its sole discretion,
LESSOR may 

                                      34
<PAGE>
 
require an opinion of counsel in connection with such sublease, including
LESSOR's rights to repossess the Aircraft in the event of an Event of Default
hereunder or under the sublease. LESSEE will not amend the terms of any approved
sublease without the prior written consent of LESSOR, which will not be
unreasonably withheld.

11.4    Assignment of Sublease.  Any approved sublease will be assigned to
        ----------------------                                            
LESSOR as security.  LESSEE will deliver the original counterpart of the
sublease to LESSOR and make any filings necessary to protect LESSOR's security 
interest.

11.5       Continued Responsibility of LESSEE.  LESSEE will continue to be
           ----------------------------------                             
responsible for performance of its obligations under this Lease during any

                                      36
<PAGE>
 
            to adopt within the Lease Term for the rest of its 737-300 aircraft
            fleet.  It is the intent of the parties that the Aircraft will not
            be discriminated from the rest of LESSEE's fleet in service bulletin
            compliance (including method of compliance) or other maintenance
            matters.  LESSEE will not discriminate against the Engines with
            respect to Overhaul build standards and life limited part
            replacements.

            (d) Incorporation in the Maintenance Program for the Aircraft of a

            (f) Providing LESSOR with written summaries of all sampling programs
            involving or affecting the Aircraft.

            (g) Maintaining in English and keeping in an up-to-date status the
            records and historical documents set forth in Attachment 1 of
            Exhibit J.

            (h) Maintaining historical records, in English, for condition-
            monitored, hard time and life limited Parts (including tags from the
            manufacturer of such Part or a repair facility which evidence that
            such Part is new or overhauled and establish authenticity, total
            time in service and time since overhaul for such Part), the hours
            and cycles the Aircraft and Engines operate and all maintenance and
            repairs performed on the Aircraft.

            (i) Properly documenting all repairs, Modifications and alterations
            and the addition, removal or replacement of equipment, systems or
            components in

                                      37
<PAGE>
 
           accordance with the rules and regulations of the Aviation Authority
           and reflecting such items in the Aircraft Documentation. In addition,
           all repairs to the Aircraft will be accomplished in accordance with
           Manufacturer's Structural Repair Manual (or FAA-approved data
           supported by FAA Form 8110-3 or equivalent). All Modifications and
           alterations will also be accomplished in accordance with FAA-approved
           data supported by FAA Form 8110-3 or equivalent.

           (j) Ensuring that Overhauls are accomplished utilizing maintenance
           and quality control procedures approved by the Aviation Authority and
           that the repair agency provides a complete record of all work
           performed during the course of such Overhaul and certifies that such
           Overhaul was accomplished, that the equipment is airworthy and
           released for return to service and that the Overhaul was in
           conformity with the original type design.

12.3       Replacement of Parts.
           -------------------- 

12.3.1     LESSEE, at its own cost and expense, will promptly replace all Parts
           which may from time to time become worn out, lost, stolen, destroyed,
           seized, confiscated, damaged beyond repair or rendered unfit or
           beyond economical repair (BER) for use for any reason. In the
           ordinary course of maintenance, service, repair, Overhaul or testing,
           LESSEE may remove any Part provided that LESSEE replaces such part as
           promptly as practicable. All replacement Parts will (i) be free and
           clear of all Security Interests (except Permitted Liens) of any kind
           or description, (ii) be in airworthy condition and of at least
           equivalent model, service bulletin and modification status and have a
           value and utility at least equal to the Parts replaced, assuming such
           replaced Parts were in the condition and repair required to be
           maintained by the terms hereof and (iii) have a current "serviceable
           tag" of the manufacturer or maintenance facility providing such items
           to LESSEE, indicating that such Parts are new, serviceable or
           Overhauled. With respect to replacement modules in an Engine, the
           replacement module will not have been previously operated at a higher
           thrust rating than the replaced module. So

                                      38
<PAGE>
 
           long as a substitution meets the requirements of the Maintenance
           Program and Aviation Authority, LESSEE may substitute for any Part a
           part that does not meet the requirements of the foregoing sentence
           if a complying Part cannot be procured or installed within the
           available groundtime of the Aircraft and as soon as practicable the
           noncomplying part is removed and replaced by a complying Part.

12.3.2     All Parts removed from the Airframe or any Engine will remain the
           property of LESSOR and subject to this Lease no matter where located,
           until such time as such Parts have been replaced by Parts (which have
           been incorporated or installed in or attached to the Airframe or such
           Engine) which meet the requirements for replacement Parts specified
           above and title to such replacement Parts has passed to LESSOR under
           the Laws of the State of Registration and lex situs. To the extent
                                                     --- -----
           permitted by the Laws of the State of Registration and the lex situs
                                                                      --- -----
           it is the intent of LESSOR and LESSEE that without further act and
           immediately upon any replacement Part becoming incorporated,
           installed or attached to the Airframe or an Engine as above provided,
           (i) title to the removed Part will thereupon vest in LESSEE, free and
           clear of all rights of LESSOR, (ii) title to the replacement Part
           will thereupon vest in LESSOR free and clear of all rights of LESSEE
           and (iii) such replacement Part will become subject to this Lease and
           be deemed to be a Part hereunder to the same extent as the Parts
           originally incorporated or installed in or attached to the Airframe
           or such Engine.

12.4       Removal of Engines.
           ------------------ 

12.4.1     If an Engine is removed for testing, service, repair, maintenance,
           Overhaul work, alterations or modifications, title to such Engine
           will at all times remain vested in LESSOR.

12.4.2     LESSEE will be entitled to remove any of the Engines from the
           Aircraft and install another engine or engines on the Aircraft,
           provided that LESSEE complies with each the following obligations:

                                      39
<PAGE>
 
           (a) The insurance requirements set forth in Article 18 and Exhibit C
           are in place.

           (b) LESSEE ensures that the identification plates referred to in
           Article 15 are not removed from any Engine upon such Engine being
           detached from the Aircraft.

           (c) Title to the Engine remains with LESSOR free from all Security
           Interests (except Permitted Liens) regardless of the location of the
           Engine or its attachment to or detachment from the Aircraft.

12.5       Installation of Engines on other aircraft.  Any Engine removed from
           -----------------------------------------                          
the Aircraft may be installed on another aircraft in LESSEE's fleet which
utilizes engines of the same type as the Engine only if one of the situations
described in this Article 12.5 exists:

12.5.1     LESSEE or LESSOR has title to such other aircraft free and clear of
           all Security Interests (except Permitted Liens).

12.5.2     LESSEE, LESSOR and all of the Creditors of LESSEE of such aircraft
           enter into a engines cooperation agreement in form and substance
           acceptable to LESSOR in which each party agrees to recognize one
           another's rights in the engines. LESSEE will reimburse LESSOR and its
           Lender for their reasonable attorneys' fees and costs in negotiating
           and finalizing engine cooperation agreement arrangements with LESSEE
           and its Creditors.

12.5.3     Such other aircraft is subject to a Creditor Agreement (but no other
           Security Interests except Permitted Liens) which by its terms
           expressly or effectively states that such Creditor and its successors
           and assigns will not acquire any right, title or interest in any
           Engine by reason of such Engine being installed on such aircraft. To
           evidence the foregoing, at or before Delivery, LESSEE will provide
           LESSOR with an opinion of counsel and officer's certificate as to
           this matter (and such an opinion of counsel and officer's certificate
           will be provided during the Lease Term with respect to other Creditor
           Agreements regarding aircraft entering

                                      40
<PAGE>
 
           LESSEE's operating fleet subsequent to Delivery). LESSEE hereby
           agrees that if LESSOR's title to an Engine is in fact impaired under
           any such Creditor Agreement, such impairment will be a Total Loss of
           such Engine and the provisions of Article 19.5 will apply. To the
           extent another Creditor Agreement contains such provisions, then
           LESSOR hereby agrees for the benefit of the Creditor of such Creditor
           Agreement that neither LESSOR nor its successors or assigns will
           acquire or claim any right, title or interest in any engine in which
           LESSEE or another Creditor has an interest as a result of such engine
           being installed on the Airframe.

12.6       Engine Thrust Rating.  If an Engine is utilized by LESSEE on the
           --------------------                                            
Aircraft or on any other airframe (or if the Engine is utilized by any sublessee
or user under a pooling arrangement in accordance with this Lease) at a thrust
rating greater than the thrust rating set forth in Exhibit A, LESSEE will
promptly notify LESSOR and the Engine Reserve amounts set forth in Article 5.4.1
will be increased in an amount proportional to the accelerated rate of
deterioration of the Engine resulting from the increased thrust rating.

12.7       Modifications.
           ------------- 

12.7.1     No modification, alteration, addition or removal to the Aircraft
           ("Modification") expected to cost over   *  U.S. Dollars (US$  *  )
           --------------                                                     
           or deviation from the Aircraft's original type design or
           configuration will be made without the prior written consent of
           LESSOR, which consent will not be unreasonably withheld.
           "Modifications" do not include airworthiness directives of the
           --------------                                                
           Aviation Authority or FAA or Manufacturer's recommended service
           bulletins, for which LESSOR consent is not required.

      AND HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION

12.7.2     LESSOR may review LESSEE's proposed designs, plans, engineering
           drawings and diagrams, and flight and maintenance manual revisions
           for any proposed Modification.  If requested by LESSOR, LESSEE will
           furnish LESSOR (at LESSEE's expense) with such documents in final
           form and any other documents required by Law, as a result of such
           Modification.  All Modifications incorporated on the Aircraft will

                                      41
<PAGE>
 
            be properly documented in the Aircraft Documentation and be fully
            approved by the Aviation Authority.

12.7.3      Notwithstanding any other provision of this Lease, no Modification
            will be made which has the effect of decreasing the utility or value
            of the Aircraft or invalidating any warranty applicable to the
            Aircraft.

12.7.4      No Modification will be made by LESSEE if an Event of Default exists
            and is continuing hereunder.

12.7.5      Unless otherwise agreed by LESSOR in writing, all permanent or
            structural Modifications will forthwith become a part of the
            Aircraft and LESSEE relinquishes to LESSOR all rights and title
            thereto.  However, all temporary and non-structural Modifications
            will remain the property of LESSEE and, at LESSOR's request and
            LESSEE's cost, will be removed from the Aircraft prior to return of
            the Aircraft, with LESSEE restoring the Aircraft to the condition it
            was in prior to the Modification in a manner cosmetically acceptable
            to LESSOR.  Notwithstanding the foregoing, no such removal will be
            permitted without LESSOR's permission after the occurrence of an
            Event of Default hereunder and immediately upon the occurrence of an
            Event of Default hereunder, without the requirement of any further
            act or notice, all right, title and interest in such Modifications
            will immediately vest in LESSOR.

12.7.6      LESSOR will bear no liability for the cost of Modifications of the
            Aircraft whether in the event of grounding or suspensions of
            certification, or for any other cause.

12.8        Pooling of Engines and Parts.  With LESSOR's prior written consent,
            ----------------------------                                       
not to be unreasonably withheld, LESSEE may subject the Engines and Parts to
normal interchange or pooling agreements with responsible international
scheduled commercial air carriers customary in the airline industry and entered

            performed for all other causes excluded, including those causes set
            forth in Article 13.5.  Subject to the Articles 13.2.2 and Article
            16.1 and excluding handling, packaging and shipping charges,
            reimbursement for an Engine will be made up to the amount in the

            LESSEE for an Engine will be designated and will be reimbursable
            solely for the replacement of life limited parts in such Engine.

with work performed for all other causes excluded, including those causes set
forth in Article 13.5.

13.4       Reimbursement.  LESSEE will be entitled to reimbursement from the 
           -------------
Reserves after the work is completed and the Airframe or Engine has left the
repair agency, by submitting invoices and proper documentation within six (6)
months after completion of the work. For the Airframe, proper documentation
includes a list of all routine and non-routine work cards with corresponding
references to the MPD and an itemized labor and materials report. For the
Engine, proper documentation includes a description of the reason for removal, a
shop teardown report, a shop findings report, a full description of the
workscope and complete disk records for the Engine both prior to and after the
shop visit. Both the invoice supplied by the Engine repair facility and that
submitted by LESSEE to LESSOR with respect to an Engine will state whether or
not credits were provided due to life remaining on any removed Engine Parts and
the amount of any such credits will be itemized.

13.5    Reimbursement Adjustment.  By way of example, among the exclusions from 
        ------------------------
reimbursement are those items resulting from repairs covered by LESSEE's or a
third party's insurance, (deductibles being for the account of LESSEE) or
required as a result of an airworthiness directive, manufacturer's service
bulletin, faulty maintenance or installation, improper operations, misuse,
neglect, accident, incident, ingestion, or other accidental cause. Reimbursement
from the Reserves will not be available for the APU, thrust reversers or any of
their associated components. All invoices subject to reimbursement from LESSOR
will be reduced (by adjustment between LESSEE and LESSOR retroactively if
necessary) by the actual amounts received by LESSEE on account of such work from
responsible third parties or other sources, such as insurance proceeds,
manufacturer's warranties, guarantees, concessions and credits (including, with
respect to Engines, credits due to life remaining on any removed Engine Parts).

13.6    Costs in Excess of Reserves.  LESSEE will be responsible for payment of 
        ---------------------------
all costs in excess of the amounts

                                      45

reimbursed hereunder. If on any occasion the balance in the Airframe or an
Engine Reserve is insufficient to satisfy a claim for reimbursement in respect
of the Airframe or such Engine, the shortfall may not be carried forward or made
the subject of any further claim for reimbursement.

13.7       Reimbursement after Termination Date.  LESSEE may not submit any
           ------------------------------------                            
invoice for reimbursement from the Reserves after the Termination Date unless on
or prior to such date LESSEE has notified LESSOR in writing that such
outstanding invoice will be submitted after the Termination Date and the
anticipated amount of such invoice. So long as LESSEE has provided such notice
to LESSOR, LESSEE may then submit such outstanding invoice at any time within
six (6) months after the Termination Date. Subject to the foregoing, any balance
remaining in the Airframe and Engine Reserves on the Termination Date, including
termination on account of a Total Loss of the Aircraft, will be retained by
LESSOR.

           ----------------------------                                       
LESSEE agrees to pay promptly when due, and to indemnify and hold harmless
LESSOR on a full indemnity basis from, all license and registration fees and all
taxes, fees, levies, imposts, duties, charges, deductions or withholdings of any
nature (including without limitation any value added, franchise, transfer,
sales, gross receipts, use, business, excise, personal property, stamp or other
tax) together with any assessments, penalties, fines, additions to tax or
interest thereon, however or wherever imposed (whether imposed upon LESSEE,
LESSOR, on all or part of the Aircraft, the Engines or otherwise), by any
Government Entity or taxing authority in the U.S. or any foreign country or by
any international taxing authority (including the City or County of Los
Angeles), upon or with respect to, based upon or measured by any of the
following (collectively, "Taxes"):

            (a) the Aircraft, the Engines or any Parts.

            (b) the use, operation or maintenance of the Aircraft or carriage of
            passengers or freight during the Lease Term.

            (c) this Lease, the payments due hereunder and the terms and
            conditions hereof.

            (d) the ownership, financing, delivery, import or export, return,
            sale, payment of Total Loss Proceeds or other disposition of the
            Aircraft.

16.2        Exceptions to Indemnity.  The indemnity provided for in Article 16.1
            -----------------------                                             
does not extend to any of the following Taxes:

            (a) Imposed by the U.S. or the State of California on the net
            income, gross receipts, capital or net worth of LESSOR.

            (b) Attributable to the period prior to Delivery or after return of
            the Aircraft to LESSOR in accordance with this Lease.

16.3       After-Tax Basis.  The amount which LESSEE is required to pay
           ---------------                                             
with respect to any Taxes indemnified against under Article 16.1 is an amount
sufficient to restore LESSOR on an after-tax basis to the same position LESSOR
would have been in had such Taxes not been incurred.

16.4       Timing of Payment.  Any amount payable to LESSOR pursuant to this
           -----------------                                                
Article 16 will be paid within ten (10) days after receipt of a written demand
therefor from LESSOR accompanied by a written statement describing in reasonable
detail the basis for such indemnity and the computation of the amount so payable
provided, however, that such amount need not be paid by LESSEE prior to the
earlier of (i) the date any Tax is payable to the appropriate Government Entity
or taxing authority or (ii) in the case of amounts which are being contested by
LESSEE in good faith or by LESSOR pursuant to Article 16.5, the date such
contest is finally resolved.

16.5       Contests.  If claim is made against LESSOR for Taxes with respect to

which LESSEE is liable for a payment or indemnity under this Lease, LESSOR will
promptly give LESSEE notice in writing of such claim provided, however, that
LESSOR's failure to give notice will not relieve LESSEE of its obligations
hereunder unless such failure materially impairs or precludes LESSEE's ability
to contest the claim.  So long as (i) a contest of such Taxes does not involve
any danger of the sale, forfeiture or loss of the Aircraft or any interest
therein, (ii) if LESSOR so requests, LESSEE has provided LESSOR with an opinion
of independent tax counsel that a reasonable basis exists for contesting such
claim and (iii) adequate reserves have been made for such Taxes or, if required,
an adequate bond has been posted, then LESSOR at LESSEE's written request will
in good faith, with due diligence and at LESSEE's expense, contest (or permit
LESSEE to contest in the name of LESSEE or LESSOR) the validity, applicability
or amount of such Taxes.

16.6       Refunds.  Upon receipt by LESSOR of a refund of all or any part of
           -------                                                           
any Taxes (including any deductions or withholdings referred to in Article 5.8)
which LESSEE has paid, LESSOR will pay to LESSEE the net amount of such Taxes
refunded.

           ---------------------------------                                   
with one another in providing information which may be reasonably required to
fulfill each party's tax filing requirements and any audit information request
arising from such filing.

other type, of such Indemnitee, so long as such Expense does not fall within any

            (d) Expenses due to the breach by LESSOR of its covenant of quiet
            enjoyment pursuant to Article 21.2.1 (except to the extent covered
            by LESSEE's insurances).

17.3        After-Tax Basis.  The amount which LESSEE will be required to pay
            ---------------                                                  
with respect to any Expense indemnified against under Article 17.1 will be an
amount sufficient to restore the Indemnitee, on an after-tax basis, to the same
position such Indemnitee would have been in had such Expense not been incurred.

17.4        Timing of Payment.  It is the intent of the parties that each
            -----------------                                            
Indemnitee will have the right to indemnification for Expenses hereunder as soon
as a claim is made and as soon as an Expense is incurred, whether or not
meritorious and whether or not liability is established (but subject to Article
17.8). LESSEE will pay an Indemnitee for Expenses pursuant to this Article 17
within ten (10) days after receipt of a written demand therefor from such
Indemnitee accompanied by a written statement describing in reasonable detail
the basis for such indemnity.

17.5       Subrogation.  Upon the payment in full of any indemnity pursuant to
           -----------                                                        
this Article 17 by LESSEE, LESSEE will be subrogated to any right of the
Indemnitee in respect of the matter against which such indemnity has been made.

17.6       Notice.  Each Indemnitee and LESSEE will give prompt written notice
           ------                                                             
one to the other of any liability of which such party has knowledge for which
LESSEE is, or may be, liable under Article 17.1 provided, however, that failure
to give such notice will not terminate any of the rights of Indemnitees under
this Article 17 except to the extent that LESSEE has been materially prejudiced
by the failure to provide such notice.

17.7       Refunds.  If any Indemnitee obtains a recovery of all or any part of
           -------                                                             
any amount which LESSEE has paid to such Indemnitee, such Indemnitee will pay 
to LESSEE the net amount recovered by such Indemnitee.

17.8       Defense of Claims.  Unless a Default has occurred and is continuing,
           -----------------                                                   
LESSEE and its insurers will have the right (in each such case at LESSEE's sole
expense) to investigate or, provided that LESSEE or its insurers have not
reserved the right to dispute liability with respect to any insurance policies
pursuant to which coverage is sought, defend or compromise any claim covered by
insurance for which indemnification is sought

                                      54
<PAGE>
 
pursuant to Article 17.1 and each Indemnitee will cooperate with LESSEE or its
insurers with respect thereto. If LESSEE or its insurers are retaining attorneys
to handle such claim, such counsel must be reasonably satisfactory to the
Indemnitees. If not, the Indemnitees will have the right to retain counsel of
their choice at LESSEE's expense.

17.9       Survival of Obligation.  Notwithstanding anything in this Lease to
           ----------------------                                            
the contrary, the provisions of this Article 17 will survive the Termination
Date and continue in full force and effect notwithstanding any breach by LESSOR
or LESSEE of the terms of this Lease, the termination of the lease of the
Aircraft to LESSEE under this Lease or the repudiation by LESSOR or LESSEE of
this Lease.

           -----------------------                                          
Termination Date LESSEE will, at its own expense, effect and maintain in full
force and effect the types of insurance and amounts of insurance (including
deductibles) described in Exhibit C through such brokers and with such insurers
as may be approved by LESSOR, such approval not to be unreasonably withheld, in
London or New York or such other insurance markets as mutually agreed upon by
the parties.

18.2       Insurance for Indemnities.  The insurance referred to in Article 18.1
           -------------------------                                            
will in each case include and insure (to the extent of the risks covered by the
policies) the indemnity provisions of Article 17 and LESSEE will maintain such
insurance of the indemnities for a minimum of two (2) years following the
Termination Date.

18.3       Renewal.  Not less than five (5) Business Days before the expiration
           -------                                                             
or termination date of any insurance required hereunder, LESSEE will provide
LESSOR with telex or fax confirmation from LESSEE's insurance brokers that
renewed certificates of insurance evidencing the renewal or replacement of such
insurance and complying with Exhibit C will be issued on the termination date of
the prior certificate. Within seven (7) days after such renewal, LESSEE will
furnish its brokers' certificates of insurance to LESSOR.

18.4       Assignment of Rights by LESSOR.  If LESSOR assigns all or any of its
           ------------------------------                                      
rights under this Lease as permitted by this Lease or otherwise disposes of any
interest in the Aircraft to any other Person, LESSEE will, upon request, procure
that such Person hereunder be added as loss payee and/or additional assured in
the policies effected hereunder and enjoy the same rights and insurance enjoyed
by LESSOR under such policies. LESSOR will nevertheless continue to be covered
by such policies.

18.5       Deductibles.  If there is a material adverse change in the financial
           -----------                                                         
condition of LESSEE which LESSOR reasonably believes will not enable LESSEE to
pay the deductible upon the occurrence of a partial loss of the Aircraft or an
Engine, then LESSOR may require LESSEE at LESSEE's expense to lower its
deductibles on the insurance maintained hereunder to a level which is available
on commercially reasonable terms in the insurance market.

18.6       Other Insurance.  LESSOR may from time to time by notice to
           ---------------                                            
LESSEE require LESSEE at LESSEE's expense to effect such other insurance or such
variations to the terms of the existing insurance as may then be customary in
the airline industry for aircraft of the same type as the Aircraft and for
airlines of a similar size and operational profile and at the time commonly
available in the insurance market.

18.7       Information.  LESSEE will provide LESSOR with any information
           -----------                                                  
reasonably requested by LESSOR from time to time concerning the insurance
maintained with respect to the Aircraft or in connection with any claim being
made or proposed to be made thereunder.

18.8       Currency.  All proceeds of insurance pursuant to this Lease will be
           --------                                                           
payable in Dollars except as may be otherwise agreed by LESSOR.

18.9       Grounding of Aircraft.  If at any time any of the insurance required
           ---------------------                                               
pursuant to this Lease will cease to be in full force and effect, LESSEE will
forthwith ground the Aircraft and keep the Aircraft grounded until such time as
such insurance is in full force and effect again.

18.10      Failure to Insure.  If at any time LESSEE fails to maintain
           -----------------                                          
insurance in compliance with this Article 18, LESSOR will be entitled but not
bound to do any of the following (without prejudice to any other rights which it
may have under this Lease by reason of such failure):

           (a) To pay any premiums due or to effect or maintain insurance
           satisfactory to LESSOR or otherwise remedy such failure in such
           manner as LESSOR considers appropriate (and LESSEE will upon demand
           reimburse LESSOR in full for any amount so expended in that
           connection).

           (b) At any time while such failure is continuing, to require the
           Aircraft to remain at any airport or (as the case may be), proceed
           to and remain at any airport designated by LESSOR, until such
           failure is remedied to LESSOR's satisfaction.

18.11      Reinsurance.  In the event that LESSEE elects to reinsure during the 
           -----------
Lease Term, any reinsurance will be maintained with reinsurers and brokers 
approved by LESSOR.  Such

                                      57
<PAGE>
 
reinsurance will contain each of the following terms and will in all other
respects (including amount) be satisfactory to LESSOR:

            (a) The same terms as the original insurance.

            (b) A cut-through and assignment clause satisfactory to LESSOR.

            (c) Payment will be made notwithstanding (i) any bankruptcy,
            insolvency, liquidation or dissolution of any of the original
            insurers and/or (ii) that the original insurers have made no payment
            under the original insurance policies.

18.12       Limit on Hull in favor of LESSEE.  LESSEE may carry hull all
            --------------------------------                            
risks on the Aircraft in excess of the Agreed Value (which is payable to LESSOR)
only to the extent such excess insurance which would be payable to LESSEE in the
event of a Total Loss does not exceed ten percent (10%) of the Agreed Value and
only to the extent that such additional insurance will not prejudice the
insurances required herein or the recovery by LESSOR thereunder. LESSEE agrees
that it will not create or permit to exist any liens or encumbrances over the
insurances, or its interest therein, except as constituted by this Lease.

19.3        Total Loss of Aircraft or Airframe.  If the Total Loss of the

            (d) Upon receipt by LESSOR of all monies payable by LESSEE in
            Article 19.3, provided no Default has occurred and is continuing,
            this Lease will terminate except for LESSEE's obligations under
            Articles 10.5, 16 and 17 which survive the Termination Date.

FOR AVOIDANCE OF DOUBT, THE AGREED VALUE OF THE AIRCRAFT WILL BE PAYABLE TO
LESSOR PURSUANT TO THIS ARTICLE 19.3 WHEN A TOTAL LOSS OF THE AIRFRAME OCCURS
EVEN IF THERE HAS NOT BEEN A TOTAL LOSS OF AN ENGINE OR ENGINES.

19.4        Surviving Engine(s).  If a Total Loss of the Airframe occurs
            -------------------                                         
and there has not been a Total Loss of an Engine or Engines, then, provided no
Default has occurred and is continuing, at the request of LESSEE (subject to
agreement of relevant insurers) and on receipt of all monies due under Article
19.3 and payment by LESSEE of all airport, navigation and other charges on the
Aircraft, LESSOR will transfer all its 

                                      61
<PAGE>
 
right, title and interest in the surviving Engine(s) to LESSEE, but without any
responsibility, condition or warranty on the part of LESSOR other than as to
freedom from any LESSOR's Lien.

19.5       Total Loss of Engine and not Airframe.
           ------------------------------------- 

19.5.1     Upon a Total Loss of any Engine not installed on the Airframe or a
           Total Loss of an Engine installed on the Airframe not involving a
           Total Loss of the Airframe, LESSEE will give LESSOR prompt written
           notice thereof.  LESSEE will replace such Engine as soon as
           reasonably possible by duly conveying to LESSOR title to another
           engine (i) free and clear of all Security Interests (except
           Permitted Liens) of any kind or description, (ii) in airworthy
           condition and of the same or improved model, service bulletin and
           modification status and having a value and utility at least equal to
           the Engine which sustained the Total Loss, (iii) not older (by
           reference to serial number of manufacture date) than the older of
           the two Engines delivered by LESSOR to LESSEE with the Aircraft on
           the Delivery Date, (iv) in the same or better operating condition as
           the Engine which sustained a Total Loss, including time in service,
           hours and cycles since new and hours and cycles available to the
           next inspection, Overhaul or scheduled or anticipated removal and
           (v) has not and does not have any modules that have been operated at
           a higher thrust rating than the Engine which sustained the Total
           Loss.  Such replacement engine will be an Engine as defined herein
           and the Engine which sustained such Total Loss will cease to be an
           Engine.

19.5.2     LESSEE agrees at its own expense to take such action as LESSOR may
           reasonably request in order that any such replacement Engine becomes
           the property of LESSOR and is leased hereunder on the same terms as
           the destroyed Engine. LESSEE's obligation to pay ent will continue in
           full force and effect, but an amount equal to the Net Total Loss
           Proceeds received by LESSOR with respect to such destroyed Engine
           will, subject to LESSOR's right to deduct therefrom any amounts then
           due and payable by LESSEE under this Lease, be paid to LESSEE.

                                      62
<PAGE>
 
19.5.3     Notwithstanding Articles 19.5.1 and 19.5.2, if at the time of a Total
           Loss of an Engine not installed on the Aircraft or a Total Loss of
           an Engine installed on the Airframe not involving a Total Loss of
           the Airframe, LESSOR and LESSEE are parties to a spare engine lease
           pursuant to which LESSOR is leasing a spare engine to LESSEE of the
           same model and type as the Engine which has suffered such Total
           Loss, LESSOR will receive from LESSEE the replacement cost of the
           Engine instead of accepting a replacement engine.  One (1) of such
           LESSOR spare engines will then be substituted under this Lease for
           the Engine which suffered such Total Loss and the applicable spare
           engine lease will terminate.

19.6       Other Loss or Damage.
           -------------------- 

19.6.1     If the Aircraft or any part thereof suffers loss or damage not
            constituting a Total Loss of the Aircraft or the Airframe or any
            Engine, all the obligations of LESSEE under this Lease (including
            payment of Rent) will continue in full force.

19.6.2     In the event of any loss or damage to the Aircraft or Airframe which
           does not constitute a Total Loss of the Aircraft or the Airframe, or
           any loss or damage to an Engine which does not constitute a Total
           Loss of such Engine, LESSEE will at its sole cost and expense fully
           repair the Aircraft or Engine in order that the Aircraft or Engine
           is placed in an airworthy condition and substantially the same
           condition as it was prior to such loss or damage.  All repairs will
           be performed in a manner which preserves and maintains all

           event that LESSOR does not agree with LESSEE's proposals for repair,
           LESSOR will so notify LESSEE within two (2) Business Days after its
           receipt of such proposal. LESSEE and LESSOR will then consult with
           Manufacturer and LESSEE and LESSOR agree to accept as conclusive, and
           be bound by, Manufacturer's

            directions or recommendations as to the manner in
            which to carry out such repairs.  If Manufacturer declines to give
            directions or recommendations, LESSEE will carry out the repairs in
            accordance with the directions of LESSOR.

19.6.3      To the extent insurance proceeds received by LESSEE directly from
            its insurers do not cover the cost of such repair work on the
            Aircraft or Engine and LESSOR has received additional insurance
            proceeds from LESSEE's insurers with respect to such repair work,
            LESSOR will (subject to LESSOR's right to deduct therefrom any
            amounts then due and payable by LESSEE under this Lease and
            submission by LESSEE of reasonable documentation in support of such
            excess repair costs) pay to LESSEE insurance proceeds received by
            LESSOR as and when such repair work is performed on the Aircraft.

           ------------------------

requisitioned for use by any Government Entity and such requisition does not
constitute a Total Loss, LESSEE will promptly notify LESSOR of such requisition.
All of LESSEE's obligations hereunder will continue as if such requisition had
not occurred. So long as no Default has occurred and is continuing, all payments
received by LESSOR or LESSEE from such Government Entity will be paid over to or
retained by LESSEE. If a Default has occurred and is continuing, all payments
received by LESSEE or LESSOR from such Government Entity may be used by LESSOR
to satisfy any obligations owing by LESSEE.

19.9       LESSOR Retention of Reserves.  For avoidance of doubt, the parties
           ----------------------------                                      
agree that notwithstanding the Total Loss of the Airframe and/or Engines LESSOR
will retain all Airframe and Engine Reserves paid by LESSEE and not payable to
LESSEE pursuant to Article 13.4.

23.1    Date of Return.  LESSEE is obligated to return the Aircraft, Engines,
        --------------                                                       
Parts and Aircraft Documentation to LESSOR on the Expiration Date, unless a
Total Loss of the Aircraft occurred prior to the Expiration Date and this Lease
was terminated early in accordance with Article 19.3. If LESSEE is in Default
hereunder by failing to return the Aircraft on the Expiration Date or if an
Event of Default occurs prior to the Expiration Date and LESSOR repossesses the
Aircraft, the return requirements set forth in this Article 23 nonetheless must
be met on the date the Aircraft is actually returned to LESSOR or repossessed by
LESSOR.

23.2    Technical Reporting.  Six (6) months prior to the Expiration Date
        -------------------                                              
(and in an updated form at return of the Aircraft), LESSEE will provide LESSOR
with a technical report substantially in the form and substance of Exhibit , as
revised, and, in addition upon LESSOR's request, will make copies available of
(i) drawings of the interior configuration of the Aircraft both as it presently
exists and as it will exist at return, (ii) airworthiness directive status list,
(iii) service bulletin incorporation list, (iv) rotable controlled, hard time
and life limited component listings, (v) listing of LESSEE-initiated
modifications and alterations, (vi) interior material burn certificates, (vii)
Aircraft maintenance program, (viii) complete workscope for the checks,
inspections and other work to be performed prior to return, (ix) current Engine
disk sheets and (x) any other data which is reasonably requested by LESSOR.

23.3    Return Location.  LESSEE at its expense will return the Aircraft,

23.5    Aircraft Inspection.
        ------------------- 

23.5.1  During the maintenance checks performed immediately prior to the
        proposed redelivery and at the actual return of the Aircraft, LESSOR
        and/or its representatives will have an opportunity to conduct a full
        systems functional and operational inspection of the Aircraft (and other
        types of reasonable inspections based upon the Aircraft type, age, use
        and other known factors with respect to the Aircraft) and a full
        inspection of the Aircraft Documentation (including records and
        manuals), all to LESSOR's satisfaction. Any deficiencies from the
        Aircraft return condition requirements set forth in this Article 23 will
        be corrected by LESSEE at its cost prior to the acceptance flight
        described in Article 23.5.2.

23.5.2  Immediately prior to the proposed redelivery of the Aircraft, LESSEE
        will carry out for LESSOR and/or LESSOR's representatives an Aircraft
        acceptance flight in accordance with Manufacturer's standard flight
        operation check flight procedures or, if agreed to in writing by LESSOR,
        in accordance with an airline acceptance flight procedure, either of
        which will be for the duration necessary to perform such check flight
        procedures but in any event not less than two (2) hours. Flight costs
        and fuel will be furnished by and at the expense of LESSEE. Any
        deficiencies from the Aircraft return condition requirements set forth
        in this Article 23 will be corrected by LESSEE at its cost prior to
        return of the Aircraft.
        
23.5.3  To the extent that the ground inspection and acceptance flight extend
        beyond the Expiration Date, the Lease Term will be deemed to have been
        automatically extended and the obligations of LESSEE hereunder
        (including Article 23.11(c)) will continue on a day-to-day basis until
        the Aircraft is accepted by LESSOR executing the Return Acceptance
        Receipt.

23.6    Certificate of Airworthiness Matters.
        ------------------------------------ 

23.6.1  The Aircraft will possess a current Certificate of Airworthiness
        issued by the Aviation Authority

                                      73
<PAGE>
 
        (although this Certificate of Airworthiness may later be substituted by
        the Export Certificate of Airworthiness or equivalent if requested by
        LESSOR pursuant to Article 23.10). In addition, even if LESSEE must
        perform engineering, maintenance and repair work on the Aircraft beyond
        the requirements of Article 12, the Aircraft at return must be in the
        condition required in order to meet the requirements for issuance of a
        U.S. Standard Certificate of Airworthiness for transport category
        aircraft issued by the FAA in accordance with FAR Part 21 and, in
        addition, to meet the operating requirements of FAR Part 121.

23.6.2  If the Aircraft is registered outside the U.S. at the time of return and
        a certificate of airworthiness is issued by an airworthiness authority
        other than the FAA, then at LESSOR's request, LESSEE at its cost will
        demonstrate that the Aircraft meets the requirements for issuance of the
        U.S. Standard Certificate of Airworthiness for transport category
        aircraft specified in Article 23.6.1 by delivering to LESSOR a letter or
        document acceptable to LESSOR signed by an FAA Designated Airworthiness
        Representative (DAR) stating that the DAR has inspected the Aircraft and
        Aircraft Documentation (including records and manuals) and has found
        that the Aircraft meets the requirements for issuance of a U.S. Standard
        Certificate of Airworthiness for transport category aircraft in
        accordance with FAR Part 21.

23.6.3  If the Aircraft is to be registered in a country other than in the U.S.
        after return from LESSEE, LESSOR may in its sole discretion waive the
        requirements of Article 2362 and instead require that LESSEE at its
        expense (to the extent such expense is no greater than that which LESSEE
        would have incurred pursuant to Articles 23.6.1 and 23.6.2, with any
        additional expenses being for LESSOR's account) put the Aircraft in a
        condition to meet the requirements for issuance of a Certificate of
        Airworthiness of the Aviation Authority of the next country of register,
        provided that if solely as a result of such work the Aircraft is
        returned after the scheduled redelivery date, LESSEE will not be

                                      74
<PAGE>
 
        liable for payment of Rent in respect of the period following date the
        Aircraft would have been returned following completion of the
        requirements of this Article 23, but for the provisions of this Article
        23.6.3.

23.7    General Condition of Aircraft at Return.
        --------------------------------------- 

23.7.1  The Aircraft, Engines and Parts will have been maintained and repaired
        in accordance with the Maintenance Program, the rules and regulations of
        the Aviation Authority and this Lease.

23.7.2  Aircraft Documentation (including records and manuals) will have been
        maintained in an up-to-date status, in accordance with the rules and
        regulations of the Aviation Authority and the FAA and this Lease and
        will be in a form necessary in order to meet the requirements of Article
        23.6.2. The records and historical documents set forth in Attachment 1
        of Exhibit J will be in English.

23.7.3  The Aircraft will be in the same working order and condition as at
        Delivery (subject to the other provisions of this Article 23,
        reasonable wear and tear from normal flight operations excepted), with
        all pilot discrepancies and deferred maintenance items cleared on a
        terminating action basis.

23.7.4  The Aircraft will be airworthy (conform to type design and be in a
        condition for safe operation), with all Aircraft equipment, components
        and systems operating in accordance with their intended use and within
        limits approved by Manufacturer, Aviation Authority and FAA.

23.7.5  The Aircraft interior (including cabin and windows) and exterior will be
        clean and cosmetically acceptable to LESSOR, with all compartments free
        of foreign objects, dirt, grease, fluids, stains, grime, cracks, tears
        and rips and ready to be placed into immediate commercial airline
        operations. 

23.7.6  No special or unique Manufacturer, Engine manufacturer or Aviation
        Authority inspection or check requirements which are specific to the
        Aircraft

                                      75
<PAGE>
 
        or Engines (as opposed to all aircraft or engines of their types) will
        exist with respect to the Airframe, Engines and Aircraft equipment,
        components and systems.

23.7.7  All repairs, modifications and alterations to the Aircraft will have
        been accomplished in accordance with Manufacturer's Structural Repair
        Manual (or FAA-approved data supported by FAA Form 8110-3).

23.7.8  The Aircraft will be returned with the Engines installed and with the
        same equipment as at Delivery, subject only to those replacements,
        additions and Modifications permitted under this Lease.

23.7.9  All airworthiness directives and other instructions of the Aviation
        Authority and FAA applicable to the Aircraft which are issued prior to
        the date of return of the Aircraft and require compliance (either by
        means of repetitive inspections, modifications or terminating action)
        prior to return of the Aircraft to LESSOR will have been complied with
        on the Aircraft on a terminating action basis. Any airworthiness
        directives of the Aviation Authority or FAA which are issued during the
        Lease Term and must be completed within one hundred eighty (180) days
        after the Termination Date must also be performed on a terminating
        action basis by LESSEE at LESSEE's cost. Airworthiness directives and
        instructions which do not have a terminating action will be accomplished
        at the highest level of inspection or modification possible. If, after
        using best efforts, LESSEE is unable to acquire the material, parts or
        components necessary to accomplish such airworthiness directive, LESSEE
        will pay to LESSOR upon return of the Aircraft the estimated cost of
        terminating such airworthiness directive. If the estimated cost cannot
        be mutually agreed upon by LESSEE and LESSOR, LESSEE and LESSOR will
        each obtain an estimate from a reputable FAA approved maintenance
        facility and the estimated cost will be the average of the two
        estimates.

23.7.10 The Aircraft will be in compliance with Manufacturer's Corrosion
        Prevention and Control

                                      76
<PAGE>
 
        Program (CPCP) specified for the model type by Manufacturer.

23.7.11 If any waivers, alternate means of compliance, dispensations, extensions
        or carry-overs with respect to airworthiness directives or operating or
        maintenance requirements are granted by the Aviation Authority or
        permitted by the Maintenance Program, LESSEE at its sole cost and
        expense will nonetheless perform such airworthiness directives and other
        operating or maintenance requirements on a terminating action basis as
        if such waivers, alternate means of compliance, dispensations or
        extensions did not exist.

23.7.12 The Aircraft will be free from any Security Interest except LESSOR's
        Liens and no circumstance will have so arisen whereby the Aircraft is or
        could become subject to any Security Interest or right of detention or
        sale in favor of the Aviation Authority, any airport authority, or any
        other authority.

23.7.13 All no-charge vendor and Manufacturer's service bulletin kits received
        by LESSEE for the Aircraft but not installed thereon will be on board
        the Aircraft as cargo. At LESSOR's request, any other service bulletin
        kit which LESSEE paid for will also be delivered to LESSOR on board the
        Aircraft, but LESSOR will reimburse LESSEE for its actual out-of-pocket
        costs for such kit, unless LESSEE purchased such kit as part of its
        implementation of a service bulletin on its fleet of aircraft of the
        same type of the Aircraft but had not yet installed such kit on the
        Aircraft, in which case such kit will be furnished free of charge to
        LESSOR.

23.7.14 The Aircraft will be free of any system-related leaks and any damage
        resulting therefrom. All repairs will have been performed on a permanent
        basis in accordance with the applicable manufacturer's instructions.

23.7.15 The Aircraft fluid reservoirs (including oil, oxygen, hydraulic and
        water) will be serviced to full and the waste tank serviced in
        accordance with Manufacturer's

                                      77
<PAGE>
 
        instructions.  Each fuel tank will be at least as full as at
        Delivery.

23.7.16 All fuel tanks will have recently undergone an anti-fungus/biological
        growth contamination laboratory evaluation, with appropriate correction
        taken in the event of excessive levels of contamination are identified.

23.7.17 At LESSOR's request, LESSEE will provide LESSOR with a written summary
        of all sampling programs involving or affecting the Aircraft.

23.8    Checks Prior to Return.  Immediately prior to return of the Aircraft
        ----------------------                                              
to LESSOR, LESSEE at its expense will do each of the following:

        (a) Have performed, by an FAA-approved repair station, the next
        scheduled full block zonal, systems and structural "C" check (or its
        equivalent), the corresponding lower checks ("A" and "B" or equivalent)
        and any other maintenance and inspections tasks, all in accordance with
        the MPD, sufficient to clear the Aircraft for operation until the next
        scheduled full block zonal, systems and structural "C" check (or its
        equivalent) under the MPD (which in any event will not be less than one
        year). LESSEE will also weigh the Aircraft. Any discrepancies revealed
        during such inspection will be corrected in accordance with
        Manufacturer's maintenance and repair manuals or FAA-approved data.
        LESSEE agrees to perform during such check any other work reasonably
        required by LESSOR (and not otherwise required under this Lease) and
        LESSOR will reimburse LESSEE for such work at LESSEE's preferred
        customer rates.

        (b) Perform an internal and external corrosion inspection in accordance
        with the recommendations of Manufacturer and as required by the
        Maintenance Program and correct any discrepancies in accordance with the
        recommendations of Manufacturer and the Structural Repair Manual. In
        addition, all inspected areas will be properly treated with corrosion
        inhibitor as recommended by Manufacturer.

                                      78
<PAGE>
 
            (c) If LESSEE performed any structural inspections/tasks on a
            sampling basis but did not perform such inspections/tasks on the
            Aircraft, such work also will be accomplished on the Aircraft.

            (d) Remove LESSEE's exterior markings, including all exterior paint,
            by stripping (or, at LESSOR's option, pneumatically scuff/sanding)
            the paint from the Airframe and clean, reseal, refinish, prepare
            (including application of alodine or another corrosion inhibitor)
            and prime the surfaces to be painted, all in accordance with
            Manufacturer's and paint manufacturer's recommendations.  LESSEE
            will then repaint the Airframe in the colors and logo specified by
            LESSOR, provided, however, that if such colors and logo are
            substantially more complex than those of LESSEE, at LESSOR's
            discretion, LESSOR will either (i) pay to LESSEE an amount equal to
            the incremental cost of repainting the Aircraft in such complex
            colors and logo over and above the cost of repainting the Aircraft
            in LESSEE's colors and logo at such time or (ii) permit LESSEE to
            return the Aircraft repainted white and to pay LESSOR an amount
            equal to the incremental cost of painting the colors and logo
            required by LESSOR's next operator, up to an amount equal to the
            amount that would have been required to paint the Aircraft in
            LESSEE's livery.  Such painting will be accomplished in such a
            manner as to result in a uniformly smooth and cosmetically
            acceptable aerodynamic surface.  All external placards, signs and
            markings will be properly attached, free from damage, clean and
            legible.

            (e) Clean the exterior and interior of the Aircraft.

            (f) If reasonably required by LESSOR, repaint the interior of the
            Aircraft, including flight deck, and replace placards.

            (g) In accordance with Manufacturer's Structural Repair Manual,
            permanently repair damage to the Aircraft that exceeds
            Manufacturer's limits and replace any non-flush structural patch
            repairs installed on the Airframe with flush-type repairs, except
            where a Manufacture's service bulletin or the Structural Repair
            Manual specifies non-flush repairs.

                                      79
<PAGE>
 
            (h) Perform full and complete hot and cold section videotape
            borescope on each Engine and its modules in accordance with the
            Engine manufacturer's maintenance manual, with LESSOR or its
            representatives entitled to be present. LESSEE will provide evidence
            to LESSOR's satisfaction that such inspection does not reveal any
            condition which would cause the Engine or any module to be
            unserviceable, beyond serviceable limits or serviceable with
            limitations under the Engine manufacturer's maintenance manual.
            LESSEE will correct any discrepancies in accordance with the
            guidelines set out by the Engine manufacturer which may be
            discovered during such inspection.

            (i) If the Engine historical and technical records and/or condition
            trend monitoring data of any Engine (including the APU) indicate an
            acceleration in the rate of deterioration in the performance of an
            Engine, LESSEE will correct, to LESSOR's satisfaction, such
            conditions which are determined to be causing such accelerated rate
            of deterioration.

            (j) In accordance with the applicable maintenance manual, accomplish
            a maximum power assurance run and condition, acceleration and bleed
            valve scheduling checks on the Engines.  LESSEE will record and
            evaluate the Engine performance, with LESSOR and/or its
            representative entitled to be present.  The performance and all
            operating parameters of each Engine will be within the limits
            specified in the Manufacturer's maintenance manual.

            (k) In the event the Engine historical and technical records,
            borescope inspection, trend monitoring and other checks specified in
            (j) above result in a dispute regarding the conformity of an Engine
            with the requirements of this Article 23, LESSEE and LESSOR will
            consult with Engine manufacturer and follow Engine manufacturer's
            recommendations (including the accomplishment of an Engine test cell
            operational check) with regard to determining if such Engine
            complies with the requirements of this Article 23 and the manner in
            which any discrepancies from the requirements of this Article 23
            will be rectified.

23.9        Part Lives.  At return, the condition of the Aircraft will be
            ----------                                                   
as follows:

            (a) The Aircraft will have at least fifty percent (50%) of the full
            allotment of hours, cycles and calendar time (whichever is the more
            limiting factor) between "D" checks remaining as approved by the
            MPD.

            (b) Each Part of an Engine which has a hard time or life limit will
            have at least fifty percent (50%) of its full allotment of
            hours/cycles (whichever is the more limiting) remaining to operate
            until its next-scheduled Overhaul or removal.  In addition, each
            Engine will also have at least five thousand (5,000) hours and five
            thousand (5,000) cycles remaining until its next-anticipated full
            performance restoration shop visit (based upon the Engine
            manufacturer's estimated mean time between removals (MTBR) for
            engines of the same type as the Engines).  Each Engine will also
            have a remaining EGT margin sufficient to permit the operation of
            such Engine for the hours and cycles set forth in the preceding
            sentence, based upon the historical experience of LESSEE.

            (c) The installed APU will have zero (0) hours consumed since the
            last Overhaul (excluding hours consumed on the acceptance flight).

            (d) The installed main and nose landing gear components and their
            associated actuators, side braces and parts will have at least fifty
            percent (50%) of the full allotment of hours/cycles/calendar time
            (whichever is the more limiting factor) remaining until the next
            Overhaul or scheduled removal.

            (e) Each component or Part of the Aircraft which has a hard time
            (hour/cycle) limit to Overhaul pursuant to the MPD will have the
            greater of (i) fifty percent (50%) of the full allotment of hours
            and cycles, or (ii) the lesser of (1) five thousand (5,000) hours
            and cycles (whichever is applicable) or (2) one hundred percent
            (100%) of its total approved life remaining to operate until its
            next scheduled Overhaul pursuant to the MPD.

                                      81
<PAGE>
 
            (f) Each life-limited component or Part of the Aircraft will have
            the greater of (i) fifty percent (50%) of the full allotment of
            hours and cycles, or (ii) the lesser of (1) five thousand (5,000)
            hours and cycles or (2) one hundred percent (100%) of its total
            approved life remaining to operate pursuant to the MPD.

            (g) Each component or Part which has a calendar limit will have
            remaining to operate at least (i) one (1) year from the date of
            return of the Aircraft to LESSOR or (ii) one hundred percent (100%)
            of its total approved life, whichever is less, pursuant to the MPD.

            (h) No Engine, installed component or Part will have a total time
            since new greater than one hundred ten percent (110%) of that of the
            Airframe and, with respect to all installed components as a group,
            the components will have an average total time since new no greater
            than that of the Airframe.

            (i) The Aircraft landing gear tires and brakes will be new or have
            zero (0) hours/cycles out of Overhaul (except for the acceptance
            flight).

23.10       Export and Deregistration of Aircraft.  At LESSOR's request,
            -------------------------------------                       
LESSEE at its cost will (i) provide an Export Certificate of Airworthiness or
its equivalent from the State of Registration so that the Aircraft can be
exported to the country designated by LESSOR, (ii) assist with deregistration of
the Aircraft from the register of aircraft in the State of Registration, (iii)
assist with arranging for prompt confirmation of such deregistration to be sent
by the registry in the State of Registration to the next country of registration
and (iv) perform any other acts reasonably required by LESSOR in connection with
the foregoing.  If any Aircraft work which LESSEE is not otherwise required to
perform hereunder, including engineering, is required in order to obtain such
Export Certificate of Airworthiness, LESSEE will perform such work and LESSOR
will reimburse LESSEE for such work at LESSEE's preferred customer rates.

23.11    LESSEE's Continuing Obligations.  In the event that LESSEE
         -------------------------------                           
does not return the Aircraft to LESSOR on the Expiration

                                      82
<PAGE>
 
Date and in the condition required by this Article 23 for any reason (whether
or not the reason is within LESSEE's control):

            (a) the obligations of LESSEE under this Lease will continue in full
            force and effect on a day-to-day basis until such return.  This will
            not be considered a waiver of LESSEE's Event of Default or any right
            of LESSOR hereunder.

            (b) Until such return, the Agreed Value will be an amount equal to
            the Agreed Value on the day the Aircraft should have been returned
            to LESSOR pursuant to this Lease.

            (c) LESSEE will fully indemnify LESSOR on demand for all losses
            (including consequential damages), liabilities, actions,
            proceedings, costs and expenses thereby suffered or incurred by
            LESSOR and, in addition, until such time as the Aircraft is
            redelivered to LESSOR and put into the condition required by this
            Article 23, instead of paying the Rent specified in Article 5.3,
            LESSEE will pay twice the amount of Rent for each day from the
            scheduled Expiration Date until the Termination Date (the monthly
            Rent payable under Article 5.3.1 will be prorated based on the
            actual number of days in the applicable month). Payment will be made
            upon presentation of LESSOR's invoice.

            (d) LESSOR may elect, in its sole and absolute discretion, to accept
            the return of the Aircraft prior to the Aircraft being put in the
            condition required by this Article 23 and thereafter have any such
            non-conformance corrected at such time as LESSOR may deem
            appropriate (but within ninety (90) days following the return of the
            Aircraft) and at commercial rates then-charged by the Person
            selected by LESSOR to perform such correction.  Any direct expenses
            incurred by LESSOR for such correction will become additional Rent
            payable by LESSEE within fifteen (15) days following the submission
            of a written statement by LESSOR to LESSEE, identifying the items
            corrected and setting forth the expense of such corrections.
            LESSEE's obligation to pay such supplemental Rent will survive the
            Termination Date.

23.12       Airport and Navigation Charges.  LESSEE will ensure that at
            ------------------------------                             
return of the Aircraft any and all airport, navigation and other charges which
give rise or may if unpaid give rise to any lien, right of detention, right of
sale or other Security Interest in relation to the Aircraft, Engine or any Part,
whether incurred in respect of the Aircraft or any other aircraft operated by
LESSEE, have been paid and discharged in full (whether or not due) and will at
LESSOR's request produce evidence thereof satisfactory to LESSOR.

23.13       Return Acceptance Certificate.  Upon return of the Aircraft in
            -----------------------------                                 
accordance with the terms of this Lease, LESSEE will prepare and execute two (2)
Return Acceptance Certificates in the form and substance of Exhibit J and LESSOR
will countersign and return one such Return Acceptance Certificate to LESSEE.
In addition, LESSEE and LESSOR will execute a Lease Termination for filing with
the FAA evidencing termination of this Lease.

23.14       Indemnities and Insurance.  The indemnities and insurance
            -------------------------                                
requirements set forth in Articles 17 and 18, respectively, will apply to
Indemnitees and LESSOR's representatives during return of the Aircraft,
including the ground inspection and acceptance flight.  With respect to the
acceptance flight, LESSOR's representatives will receive the same protections as
LESSOR on LESSEE's Aviation and Airline General Third Party Liability Insurance.

23.15       Storage.  At LESSOR's request, LESSEE will continue to lease
            -------                                                     
the Aircraft under this Lease for a period not to exceed thirty (30) days.
During this period, LESSEE will have no obligations under this Lease except to
park and store the Aircraft in accordance with Manufacturer's recommended short
term storage program at LESSEE's principal maintenance facilities in Colorado,
provided that LESSOR will reimburse LESSEE for any out-of-pocket costs
associated therewith, and, at LESSOR's cost, to maintain all insurance on the
Aircraft. LESSEE will not utilize the Aircraft for any reason during this
period.

           -----------------------                                              
OR OTHER CHARGE MAY BE MADE BY LESSEE OF ANY OF ITS RIGHTS WITH RESPECT TO THE
AIRCRAFT, ENGINE OR PART OR THIS LEASE.

24.2        Sale or Assignment by LESSOR.
            ---------------------------- 

24.2.1      Subject to LESSEE's rights pursuant to this Lease, LESSOR may at any
            time and without LESSEE's consent sell, assign or transfer its
            rights and interest hereunder or with respect to the Aircraft to a
            third party ("LESSOR's Assignee").  For a period of three (3) years
                          -----------------                                    
            after such sale or assignment and at LESSEE's cost, LESSEE will
            continue to name LESSOR as an additional insured under the Aviation
            and Airline General Third Party Liability Insurance specified in
            Exhibit C.

24.2.2      The term "LESSOR" as used in this Lease means the lessor of the
            Aircraft at the time in question.  In the event of the sale of the
            Aircraft and transfer of LESSOR's rights and obligations under this
            Lease, LESSOR's Assignee will become "LESSOR" of the Aircraft under
            this Lease and the transferring party (the prior "LESSOR") will be
            relieved of all liability to LESSEE under this Lease for obligations
            arising on and after the date the Aircraft is sold.  LESSEE will
            acknowledge and accept LESSOR's Assignee as the new "LESSOR" under
            this Lease and will look solely to LESSOR's Assignee for the
            performance of all LESSOR obligations and covenants under this Lease
            arising on and after the Aircraft sale date.

24.3        LESSOR's Lender.  Subject to LESSEE's rights pursuant to this Lease,
            ---------------                                                     
LESSOR may at any time and without LESSEE's consent grant security interests
over the Aircraft and assign the benefit of this Lease to a lender ("LESSOR's
                                                                     --------
Lender") as security for LESSOR's obligations to LESSOR's Lender.  Accordingly,
- ------                                                                         
if LESSOR's Lender requires, as a condition to providing financing, any
nonsubstantive modification of this Lease, LESSEE agrees to enter into an
agreement so modifying this Lease.

LESSOR's Lender, LESSEE will execute all such documents (such as a lease
assignment agreement) as LESSOR, LESSOR's Assignee or LESSOR's Lender may
reasonably require to confirm LESSEE's obligations under this Lease and obtain
LESSEE's acknowledgement that LESSOR is not in breach of the Lease. LESSEE will
provide all other reasonable assistance and cooperation to LESSOR, LESSOR's
Assignee and LESSOR's Lender in connection with any such sale or assignment or
the perfection and maintenance of any such security interest, including, at
LESSOR's cost, making all necessary filings and registrations in the State of
Registration and providing all opinions of counsel with respect to matters
reasonably requested by LESSOR, LESSOR's Lender or LESSOR's Assignee. LESSOR
will reimburse LESSEE for its reasonable out-of-pocket costs in reviewing
documents required by LESSOR or LESSOR's Lender.

24.5        Protections.
            ----------- 

24.5.1      At LESSEE's request, LESSOR will seek to obtain for the benefit of
            LESSEE an acknowledgment from any LESSOR's Assignee or LESSOR's
            Lender that, so long as no Default has occurred and is continuing
            hereunder, such Person will not interfere with LESSEE's quiet,
            peaceful use and enjoyment of the Aircraft.

24.5.2      Wherever the term "LESSOR" is used in this Lease in relation to any
            of the provisions relating to disclaimer, title and registration,
            indemnity and insurance contained in Articles 8, 14, 17 and 18,
            respectively, or with respect to Article 20.2.7, the term "LESSOR"
            will be deemed to include LESSOR's Assignee and
            LESSOR's Lender, if applicable.

     ----------                -----------------


25.1       LESSEE Notice to LESSOR.  LESSEE will promptly notify LESSOR if
           -----------------------                                        
LESSEE becomes aware of the occurrence of any Default.

25.2       Events of Default.  The occurrence of any of the following will
           -----------------                                              
constitute an Event of Default and material breach of this Lease by LESSEE:

           (a) LESSEE fails to take delivery of the Aircraft when obligated to
           do so under the terms of this Lease.

           (b) LESSEE fails to make a Rent or other payment due hereunder in the
           manner and by the date provided herein and fails to make such payment
           within three (3) Business Days after such payment is due.

           (c) LESSEE fails to obtain or maintain the insurance required by
           Article 18.

           (d) LESSEE fails to return the Aircraft to LESSOR on the Expiration
           Date in accordance with Article 23.

           (e) LESSEE fails to observe or perform any of its other obligations
           hereunder and fails to cure the same within fifteen (15) days after
           written notice thereof to LESSEE. If such failure cannot by its
           nature be cured within fifteen (15) days, LESSEE will have the
           reasonable number of days necessary to cure such failure (not to
           exceed a period of sixty (60) days) so long as it uses diligent and
           best efforts to do so.

           (f) Any representation or warranty of LESSEE herein proves to be
           untrue in any material respect.

           (g) The registration of the Aircraft is cancelled other than as a
           result of an act or omission of LESSOR.

           (h) LESSEE abandons the Aircraft or Engines.

           (i) LESSEE or an approved sublessee no longer has unencumbered
           control (other than Permitted Liens) or

<PAGE>
 
            possession of the Aircraft or Engines, except as otherwise permitted
            by this Lease.

            (j) LESSEE threatens to or temporarily or permanently discontinues
            business or sells or otherwise disposes of all or substantially all
            of its assets.

            (k) A material adverse change occurs in the financial condition of
            LESSEE from the financial condition in effect on March 31, 1996
            which LESSOR reasonably believes will result in LESSEE's inability
            to comply with the terms of this Lease and of which LESSOR will have
            notified LESSEE.

            (l) LESSEE no longer possesses the licenses, certificates and

            bankrupt or insolvent or (iv) proposes or enters into any
            composition or other arrangement for the benefit of its creditors

            instituted or threatened with respect to LESSEE relating to the
            bankruptcy, liquidation, reorganization or protection from creditors
            of LESSEE or a substantial part of LESSEE's property.  If instituted
            by LESSEE, the same will be an immediate Event of Default.  If
            instituted by another Person, the same will be an Event of Default
            if not dismissed, remedied or relinquished within sixty (60) days.

            (o) Any order, judgment or decree is entered by any court of
            competent jurisdiction appointing a receiver, trustee or liquidator
            of LESSEE or a substantial part of its property, or if a substantial
            part of LESSEE's property is to be sequestered.  If instituted by or
            done with the consent of LESSEE, the same will be an immediate Event
            of Default.  If instituted by another Person, the same will be an

                                      88

            Event of Default if not dismissed, remedied or relinquished within
            sixty (60) days.

            (p) Any indebtedness for borrowed moneys or a guarantee or similar
            obligation owed by LESSEE with an unpaid balance of at least One
            Million U.S. Dollars (US$ 1,000,000) becomes due or is capable of
            being declared due before its stated maturity or LESSEE is in
            default under any other purchase agreement, lease, conditional sale
            agreement or other agreement pursuant to which LESSEE has possession
            of any aircraft.

            (q) LESSEE is in default under any other lease or agreement between
            LESSEE and LESSOR and the same is not cured within its specified
            cure period.

            (r) Any approved sublessee acts so as to prevent present or future
            performance by LESSEE of its obligations under this Lease.

25.3        LESSOR's General Rights.  Upon the occurrence of any Event of
            -----------------------                                      
Default, all rights of LESSEE hereunder will immediately cease and terminate
(but LESSEE's obligations hereunder will continue, including the obligations to
protect and insure the Aircraft as required under this Lease).  LESSOR may do
all or any of the following at its option (in addition to such other rights and
remedies which LESSOR may have by statute or otherwise but subject to any
requirements of applicable Law):

            (a) Terminate this Lease by giving written notice to LESSEE.

            (b) Require that LESSEE immediately move the Aircraft to an airport
            or other location designated by LESSOR.

            (c) For LESSEE's account, do anything that may reasonably be
            required to cure any default and recover from LESSEE all reasonable
            costs, including legal fees and expenses incurred in doing so and
            Default Interest.

            (d) Proceed as appropriate to enforce performance of this Lease and
            to recover any damages for the breach hereof, including the amounts
            specified in Article 25.5.

                                      89
<PAGE>
 
            (e) Terminate this Lease by taking possession of the Aircraft or by
            serving notice requiring LESSEE to return the Aircraft to LESSOR at
            the location specified by LESSOR.  If LESSOR takes possession of the
            Aircraft, it may enter upon LESSEE's premises where the Aircraft is
            located without liability.  Upon repossession of the Aircraft,
            LESSOR will then be entitled to sell, lease or otherwise deal with
            the Aircraft as if this Lease had never been made.  LESSOR will be
            entitled to the full benefit of its bargain with LESSEE.

            (f) Apply all or any portion of the Security Deposit and any other
            security deposits held by LESSOR pursuant to any other agreements
            between LESSOR and LESSEE to any amounts due.

25.4        Deregistration and Export of Aircraft.  If an Event of Default has
            -------------------------------------                             
occurred and is continuing, LESSOR may take all steps necessary to deregister
the Aircraft in and export the Aircraft from the State of Registration.

25.5        LESSEE Liability for Damages.  If an Event of Default
            ----------------------------                         
occurs, in addition to all other remedies available at law or in equity, LESSOR
has the right to recover from LESSEE and LESSEE will pay LESSOR within two (2)
Business Days after LESSOR's written demand, all of the following:

            (a) All amounts which are then due and unpaid hereunder and which
            become due prior to the earlier of LESSOR's recovery of possession
            of the Aircraft or LESSEE making an effective tender thereof.

            (b) Any losses suffered by LESSOR because of LESSOR's inability to
            place the Aircraft on lease with another lessee or to otherwise
            utilize the Aircraft on financial terms as favorable to LESSOR as
            the terms hereof or, if LESSOR elects to dispose of the Aircraft,
            the funds arising from a sale or other disposition of the Aircraft
            are not as profitable to LESSOR as leasing the Aircraft in
            accordance with the terms hereof would have been (and LESSOR will be
            entitled to accelerate any and all Rent which would have been due
            from the date of LESSOR's recovery or repossession of the Aircraft
            through the Expiration Date).

                                      90
<PAGE>
 
            (c) All costs associated with LESSOR's exercise of its remedies
            hereunder, including but not limited to repossession costs, legal
            fees, Aircraft storage costs, Aircraft re-lease or sale costs and
            LESSOR's internal costs and expenses (including the cost of
            personnel time calculated based upon the compensation paid to the
            individuals involved on an annual basis and a general LESSOR
            overhead allocation).

            (d) Any amount of principal, interest, fees or other sums paid or
            payable on account of funds borrowed in order to carry any unpaid
            amount.

            (e) Any loss, premium, penalty or expense which may be incurred in
            repaying funds raised to finance the Aircraft or in unwinding any
            financial instrument relating in whole or in part to LESSOR's
            financing of the Aircraft.

            (f) Any loss, cost, expense or liability sustained by LESSOR due to
            LESSEE's failure to redeliver the Aircraft in the condition required
            by this Lease.

            (g) Any other loss, damage, expense, cost or liability which LESSOR
            suffers or incurs as a result of the Event of Default and/or
            termination of this Lease, including an amount sufficient to fully
            compensate LESSOR for any loss of or damage to LESSOR's residual
            interest in the Aircraft caused by LESSEE's default.

25.6        Waiver of Default.  By written notice to LESSEE, LESSOR may at its
            -----------------                                                 
election waive any Default or Event of Default and its consequences and rescind
and annul any prior notice of termination of this Lease.  The respective rights
of the parties will then be as they would have been had no Default or Event of
Default occurred and no such notice been given.

25.7        Present Value of Payments.  In calculating LESSOR's damages
            -------------------------                                  
hereunder, upon an Event of Default all Rent and other amounts which would have
been due hereunder during the Lease Term if an Event of Default had not occurred
will be calculated on a present value basis using a discounting rate of four
percent (4%) per annum discounted to the earlier of the date on which LESSOR
obtains possession of the Aircraft or LESSEE makes an effective tender thereof.

25.8       Use of "Termination Date".  For avoidance of doubt, it is agreed that
           -------------------------                                            
if this Lease terminates and the Aircraft is repossessed by LESSOR due to an
Event of Default, then, notwithstanding the use of the term "Termination Date"
in this Lease, the period of the Lease Term and the "Expiration Date" will be
utilized in calculating the damages to which LESSOR is entitled pursuant to
Article 255. For example, it is agreed and understood that LESSOR is entitled
to receive from LESSEE the Rent and the benefit of LESSEE's insurance and
maintenance of the Aircraft until expiration of the Lease Term.

                                    RECITAL
                                    -------

     The Boeing Company ("Manufacturer") and Buyer have entered into an Aircraft
Purchase Agreement No. 1772, dated as of December 15, 1992 (such purchase
agreement as may be amended in accordance with the provisions thereof is
hereinafter referred to the "Purchase Agreement") under which Manufacturer has
agreed to manufacture and sell and Buyer has agreed to purchase certain Boeing
737-3Q8 aircraft.  Buyer has agreed to lease one (1) of such aircraft bearing
manufacturer's serial number 27633 (the "Aircraft") to the Agent pursuant to an
agreement between Buyer and Agent dated as of June __, 1996 (the "Lease").

     The Agent is engaged in business as a commercial air carrier and intends to
lease the Aircraft from Buyer, and Buyer is desirous of utilizing the expertise
of the Agent as Buyer's agent in all matters to which the Purchase Agreement
relates with respect to the Aircraft except certain items as indicated below,
and the Agent, as Buyer's agent, is willing to make such expertise available to
Buyer.

     Accordingly, the parties agree as follows:

     1.    Buyer hereby appoints the Agent as Buyer's sole and exclusive agent
with authority to perform, on behalf of Buyer, as

                                      101
<PAGE>
 
the Agent may in its discretion determine to be necessary or desirable:

          (a) monitor Manufacturer's production, testing and delivery of the
Aircraft in accordance with the Purchase Agreement and

          (b)   do all such other things permitted by the Purchase Agreement
related to the technical and engineering aspects of Manufacturer's production of
the Aircraft, except Buyer limits Agent's authority to perform on behalf of
Buyer on any defect that occurs during manufacture that is considered
significant in nature by Buyer as measured by the criteria set forth below.
Buyer retains the sole authority to perform on any defect meeting such criteria.

                (1)  Deviations from the drawing configuration that could affect
                future modifications, maintenance, repair or overhaul of the
                Aircraft;

                (2)  Defects that are obvious appearance items;

                (3)  Rework that requires stress concurrence to satisfy
                Manufacturer's Material Review Board (MRB) requirements;

                (4)  A high quantity of defects normally considered minor on a
                singular basis;

                (5)  Major rework requiring extensive repair or modification,
                e.g. replacement of skin panels, extensive use of oversize
                ----                                                      
                fasteners, repair of damaged areas and significant structural
                modifications;

                (6)  Rework that affects the aerodynamic drag coefficient of the
                Aircraft; or

                (7)  Rework that involves areas known to be sensitive to Buyer.

        2.    Notwithstanding anything in the provisions of paragraph 1, nothing
in this Agreement will confer authority upon or otherwise permit the Agent:

                                      102
<PAGE>
 
                (a) to exercise any power of termination under the Purchase
Agreement or

                (b) to make any payments due from Buyer to Manufacturer or to
receive on behalf of Buyer any payments due from Manufacturer under the Purchase
Agreement, or to alter any of the terms and conditions of the Purchase Agreement
or the Detail Specifications of the Aircraft.

        3.      Buyer will not revoke the appointment of and authority granted
under this Agreement to the Agent unless a termination of the Purchase Agreement
or Lease has occurred with respect to the Aircraft or the Agent has failed to
perform a material obligation under this Agreement. Notice of any such
revocation will be provided in accordance with the provisions of Article 14 of
the Purchase Agreement and given to both Manufacturer and the Agent.

        4.      Manufacturer acknowledges the appointment of the Agent for the
purpose set forth hereunder and Manufacturer and Buyer agree that due
performance by Manufacturer or Agent of an obligation under the Purchase
Agreement will constitute due satisfaction of such obligation by such party and
Buyer agrees to be bound by the acts of the Agent.

        5.      Buyer and Agent agree to identify the technical organization
and/or person(s) with the limited authority to act for Agent during production
of the Aircraft. Buyer will, if possible, provide such identification to
Manufacturer in writing, along with office space requirements for Agent, if
required, prior to or at the time of Manufacturer's acknowledgment of this
Agreement.

        6.      Nothing in this Agreement will subject Manufacturer to any
liability under the Purchase Agreement which it would not otherwise be subject
to, or modify Manufacturer's rights thereunder, or require Manufacturer to
divest itself of title to or possession of Aircraft or any other property which
is subject to the Purchase Agreement until payment therefor and delivery thereof
in accordance with the Purchase Agreement.

      LESSEE has insurance coverage for the indemnities agreed to by LESSEE

                       ---------------------------------

      From Delivery Date of Aircraft to [EXPIRATION DATE]

      It is further certified that Lessor has an interest in respect of the
      Aircraft under the Lease.  Accordingly, with respect to losses occurring
      during the period from the Effective Date until the expiry of the
      Insurance or until the expiry or agreed termination of the Lease or until
      the obligations under the Lease are terminated by any action of the
      Insured or Lessor and in consideration of the Additional Premium it is
      confirmed that the Insurance afforded by the Policy is in full force and
      effect and it is further agreed that the following provisions are
      specifically endorsed to the Policy.

     1.    UNDER THE HULL (ALL RISKS AND HULL WAR AND ALLIED RISKS) AND AIRCRAFT
           ---------------------------------------------------------------------
SPARES INSURANCES
- -----------------

           (a)   [ILFC ONLY-NO OTHER CONTRACT PARTIES] In respect of any claim
on the Aircraft that becomes payable on the basis of a Total Loss, settlement
will be made to, or to the order of Lessor as sole loss payee, up to the Agreed
Value. With respect to repairable damage to an Aircraft or Engine, LESSOR will
receive all insurance proceeds in excess of US$ 500,000,000 provided that upon
receipt by the insurance broker of written notice of a material default on the
part of LESSEE, all insurance proceeds which otherwise would be payable to
LESSEE will be made directly to LESSOR. In respect of any other claim,
settlement (net of any relevant policy deductible) will be made with such
party(ies) as may be necessary to repair the Aircraft unless otherwise agreed
after consultation between the Insurers and the insured and,

                                      107
<PAGE>
 
where necessary under the terms of the Lease the Lessor. Such payments will only
be made provided they are in compliance with all applicable laws and
regulations.

           (b) Insurers agree 50/50 settlement in terms of AVS 103.

           (c) Insurers have no right to replace the Aircraft on a Total Loss
(arranged, constructive or otherwise).

           (d) Insurers recognize that LESSEE and LESSOR have agreed that a
Total Loss of the Airframe will constitute a Total Loss of the Aircraft.

           (e) In the event of Total Loss of the Aircraft, Insurers agree to pay
LESSOR all amounts up to the Agreed Value based solely upon LESSOR's (not
LESSEE's) execution of the appropriate form of release/discharge document
Lessor may sign any required release in lieu of the Insured in the event of a
Total Loss, Constructive Total Loss or Arranged Total Loss.

          (f) "Cut-through clause": Insurers confirm that in the event of any
claim arising under the hull insurances, the Reinsurers will in lieu of payment
of the Insurers, its successors in interest and assigns, pay to the person named
as sole loss payee under the original insurances that portion of any loss due
for which the Reinsurers would otherwise be liable to pay the Insurers (subject
to proof of loss), it being understood and agreed that any such payment by any
Reinsurers will fully discharge and release such Reinsurer from any and all
further liability in connection therewith and provide for payment to be made
notwithstanding (a) any bankruptcy, insolvency, liquidation or dissolution of
the Insurers and (b) that the Insurers have made no payment under the original
insurance policies.

          (g) Insurers confirm that under the insurance policies, if the Insured
installs an engine owned by a third party on the Aircraft, either (i) the hull
insurance will automatically increase to such higher amount as is necessary in
order to satisfy both Lessor's requirement to receive the Agreed Value in the
event of a Total Loss, Constructive Total Loss or Arranged Total Loss and the
amount required by the third party engine owner, or (ii) separate additional
insurance on such engine will attach in order to satisfy separately the
requirements of the Insured to such third party engine owner.

<PAGE>
 
     2.   UNDER THE LEGAL LIABILITY INSURANCE
          -----------------------------------

          (a) Subject to the provisions of this Endorsement, the Insurance will
operate in all respects as if a separate Policy had been issued covering each
party insured hereunder, but this provision will not operate to include any
claim arising howsoever in respect of loss or damage to the Aircraft insured
under the Hull or Spares Insurance of the Insured.  Notwithstanding the
foregoing the total liability of Insurers in respect of any and all Insureds
will not exceed the limits of liability stated in the Policy.

          (b) The Insurance provided hereunder will be primary and without right
of contribution from any other insurance which may be available to the Lessor.

          (c) This Endorsement does not provide coverage for the Lessor with
respect to claims arising out of its legal liability as manufacturer, repairer,
or servicing agent of the Aircraft.

     3.   UNDER ALL INSURANCES
          --------------------

          (a) Lessor, its successors and assigns, and (with respect to Aviation
and Airline General Third Party Liability only) its directors, officers and
employees for their respective rights and interests, are included as Additional
Insured.

          (b) The cover afforded to Lessor by the Policy in accordance with this
Endorsement will not be invalidated by any act or omission (including
misrepresentation and non-disclosure) of any other person or party which results
in a breach of any term, condition or warranty of the Policy PROVIDED THAT
Lessor has not caused, contributed to or knowingly condoned the said act or
omission.

          (c) Lessor will have no responsibility for premium and insurers will
waive any right of set-off or counterclaim against Lessor except in respect of
outstanding premium in respect of the Aircraft, provided that Insurer may only
set-off for premiums against the proceeds of the hull insurance for outstanding
premiums in connection with hull all risks and hull war and allied perils
insurance.

          (d) Upon payment of any loss or claim to or on behalf of Lessor,
Insurers will to the extent and in respect of such 

                                      109
<PAGE>
 
payment be thereupon subrogated to all legal and equitable rights of Lessor
indemnified hereby (but not against Lessor). Insurers will not exercise such
rights without the consent of those indemnified, such consent not to be
unreasonably withheld. At the expense of Insurers Lessor will do all things
reasonably necessary to assist the Insurers to exercise said rights.

          (e) Except in respect of any provision for Cancellation or Automatic
Termination specified in the Policy or any endorsement thereof, cover provided
by this Endorsement may only be canceled or materially altered in a manner
adverse to Lessor by the giving of not less than thirty (30) days notice in
writing to the appointed broker.  Notice will be deemed to commence from the
date such notice is given by the Insurers.  Such notice will NOT, however, be
given at normal expiry date of the Policy or any endorsement.

     4.   EXCEPT AS SPECIFICALLY VARIED OR PROVIDED BY THE TERMS OF THE
          -------------------------------------------------------------
ENDORSEMENT:
- ------------

          (a) LESSOR IS COVERED BY THE POLICY SUBJECT TO ALL TERMS, CONDITIONS,
LIMITATIONS, WARRANTIES, EXCLUSIONS AND CANCELLATION PROVISIONS THEREOF.

          (b) THE POLICY Will NOT BE VARIED BY ANY PROVISIONS CONTAINED IN THE
LEASE WHICH PURPORT TO SERVE AS AN ENDORSEMENT OR AMENDMENT TO THE POLICY.

     SUBJECT (save as specifically stated in this Certificate) to policy terms,
conditions, limitations and exclusions.

                                    Yours faithfully,

TO BE GIVEN BY LESSEE'S IN-HOUSE GENERAL COUNSEL OR OTHER LAWYERS ACCEPTABLE TO
LESSOR


To:  International Lease Finance Corporation
     1999 Avenue of the Stars
     39th Floor
     Los Angeles, California  90067
     United States

Gentlemen:

This opinion is furnished to you pursuant to Article _______  of the Aircraft
Lease Agreement dated as of June 12, 1996 (the "Lease") between FRONTIER
AIRLINES ("LESSEE") and INTERNATIONAL LEASE FINANCE CORPORATION ("Lessor").
Defined terms in this opinion are used herein as defined in the Lease.

I have acted as counsel for the LESSEE in connection with the preparation,
execution and delivery of the Lease.

In that connection I have examined:

           (a) The Lease and Estoppel and Acceptance Certificate

           (b) The charter of the LESSEE and all amendments thereto (the
"Charter") and

           (c) Such other documents, agreements and instruments, and such
treaties, laws, rules, regulations, decrees and the like, as I have deemed
necessary as a basis for the opinions hereinafter expressed.

[          (d) All of the agreements and any amendments thereto between LESSEE
and all other lessors and lenders of LESSEE covering other aircraft operated by
LESSEE on which the Engines can be installed.]

Based upon the foregoing and having regard for legal considerations which I deem
relevant, I am of the opinion that:

     1.    LESSEE is a corporation duly incorporated, validly existing and in
good standing under the Laws of Colorado.  It has

                                      115
<PAGE>
 
the corporate power and authority to carry on its business as presently
conducted and to perform its obligations hereunder.

     2.    No authorization, approval, consent, license or order of, or
registration with, or the giving of notice to the Aviation Authority or any
other regulatory body or authority is required for the valid authorization,
execution, delivery and performance by the LESSEE of the Lease.

     3.    The Lease and the Estoppel and Acceptance Certificate have each been
duly authorized, executed and delivered by LESSEE.  Each such instrument is a
valid, enforceable and binding obligation of LESSEE except as enforceability may
be limited by bankruptcy, insolvency, reorganization or other Laws of general
application affecting the enforcement of creditors' rights.

     4.    The execution and delivery of the Lease and the Estoppel and
Acceptance Certificate, the consummation by the LESSEE of the transactions
contemplated therein and compliance by the LESSEE with the terms and provisions
thereof do not and will not contravene any Law applicable to LESSEE, or result
in any breach of or constitute any default under or result in the creation of
any lien, charge or encumbrance upon any property of LESSEE, under any
indenture, mortgage, chattel mortgage, deed of trust, conditional sales
contract, bank loan or credit agreement, corporate charter, by-law or other
agreement or instrument to which LESSEE is a party or by which LESSEE or its
properties or assets may be bound or affected.

     5.    Except for any filing or recording that may be required under the
U.S. Federal Aviation Administration and except for filing a UCC-1 Financing
Statement with the State of Colorado, no other filing or recording of any
instrument or document or any other acts are necessary or advisable under the
laws of the U.S. or Colorado to protect LESSOR's title to and ownership of the
Aircraft or in order for the Lease to constitute a valid and perfected lease of
record relating to the Aircraft, it being understood that such counsel expresses
no opinion as to the nature of the LESSOR's title to the Aircraft on the
Delivery Date.  [In opinion given at Delivery, also confirm that the filings and
other steps described have been accomplished.]

     6.    LESSEE holds all licenses, certificates and permits from applicable
governmental authorities in the United States necessary for the conduct of its
business as a certificated air carrier and performance of its obligations under
the Lease.

                                      116
<PAGE>
 
     7.    To my knowledge, there are no suits or proceedings pending or
threatened against LESSEE before any Government Entity against or affecting
LESSEE which, if adversely determined, would have a material adverse effect on
the financial condition or business of LESSEE or its ability to perform under
the Lease, except as described in the filings provided to LESSOR pursuant to
Article 22.

     8.    The obligations of LESSEE under the Lease are direct, general and
unconditional obligations of LESSEE and rank or will rank at least pari passu
with all other present and future unsecured and unsubordinated obligations
(including contingent obligations) of LESSEE, with the exception of such
obligations as are mandatorily preferred by law and not by reason of any
encumbrance.

     9.    LESSEE, under the laws of Colorado or of any other jurisdiction
affecting LESSEE, is subject to private commercial law and suit.  Neither LESSEE
nor its properties or assets have the right of immunity from suit or execution
on the grounds of sovereignty in such jurisdictions and the performance by
LESSEE of its obligations under the Lease constitute commercial acts done for
commercial purposes.

     10.   There is no applicable usury or interest limitation Law in Colorado
which may restrict the recovery of payments in accordance with the Lease.

     11.   LESSOR will not violate any Law or become liable to any tax in
Colorado by reason of entering into or performing its obligations under the

     12.   The choice of California Law to govern the Lease will be upheld in
any action in the courts of Colorado.  Any judgment given by United States or
California courts would be recognized and accepted by the courts in Colorado.

[    13.   None of the agreements and any amendments thereto between LESSEE and
all other lessors and lenders to LESSEE covering other aircraft operated by
LESSEE on which the Engines can be installed contain terms which provide or
contemplate that

                                      117

Subject:   Assignment of Rights - International Lease Finance Corporation, as
           Lessor and Frontier Airlines, as Lessee of one Boeing 737-3Q8
           Aircraft, MSN 27633

Gentlemen:

In connection with International Lease Finance Corporation's lease to Frontier
Airlines ("Lessee") of a Boeing aircraft (more fully described below), reference
is made to the following documents:

1.    Purchase Agreement No. 1772 dated as of December 15, 1992 entered into
      between The Boeing Company ("Boeing") and International Lease Finance
      Corporation ("ILFC") (the "Purchase Agreement") under which ILFC purchased
      a certain Boeing Model 737-3Q8 aircraft, bearing Manufacturer's Serial No.
      27633 (the "Aircraft").

2.    Aircraft Lease Agreement, dated as of June 12, 1996 (the "Lease"), entered
      into between ILFC and Frontier Airlines ("Lessee"), pursuant to which ILFC
      leased the Aircraft to Lessee.

Pursuant to the Lease, ILFC has leased the Aircraft to Lessee.  Included in such
Lease are the transfer to Lessee for and during the term of the Lease and
commencing on ________ __, 1997 of rights related to the Aircraft under the
Purchase Agreement.  In order to accomplish such transfer of rights, as
authorized by the provisions of Article 10 of the Purchase Agreement,

(1)   Lessee, its successors and assigns, hereby agrees to be bound by and
      comply with all applicable terms, conditions, and limitations of the
      Purchase Agreement including, without limitation, paragraph 10 Exclusion
                                                                     ---------

      Insurance, respectively, of Part E of Exhibit C (Customer Support
      ---------

                                      121

      indemnification and insurance), to the Purchase Agreement.  Lessee
      recognizes that Boeing's obligation to provide support and services to
      Lessee pursuant to Exhibit C of the Purchase Agreement is conditioned on
      the receipt by Boeing of evidence of compliance by Lessee with the
      insurance requirements set forth in paragraph 2 of Part E of Exhibit C in
      a form satisfactory to Boeing prior to the commencement of such support
      and services; and

(2)   ILFC agrees to remain responsible for any payments due Boeing with respect
      to the Aircraft under Exhibit D (Airframe and Engine Price Adjustment) of
      the Purchase Agreement and (b) with respect to any Spare Part or Leased
      Part for the Aircraft ordered by ILFC under the ILFC GTA.

(3)   Further, ILFC hereby assigns to Lessee the sole authority to exercise all
      rights and powers of ILFC with respect to the Aircraft under the Purchase
      Agreement.  Such authorization shall continue until Boeing shall have
      received from ILFC written notice to the contrary addressed to Boeing's
      Vice President, Contracts, P.O. Box 3707, Seattle, Washington 98124-2207.
      Until Boeing shall have received such notice Boeing shall be entitled to
      deal exclusively and solely with Lessee with respect to the Aircraft,
      under the Purchase Agreement and, with respect to the rights, powers,
      duties or obligations under the Purchase Agreement, and all actions taken
      by Lessee or agreements entered into by Lessee during the period prior to
      Boeing's receipt of such notice, shall be final and binding upon ILFC.

(4)   Lessee hereby accepts the authorization set forth in paragraph (3) herein
      and agrees to be bound by and to comply with all the terms, conditions and
      limitations of the Purchase Agreement.

      We request that Boeing, upon receipt of this letter, acknowledge receipt
thereof and the transfer of rights, under the Purchase Agreement as set forth
above, by signing the  acknowledgment set forth below and forwarding one copy of
this letter, so acknowledged, to each of the undersigned.
