                           Midway Airlines Corporation

                          Notes to Financial Statements
          (Information as of September 30, 1999 and for the three month
                          and nine month periods ended
                   September 30, 1999 and 1998 are unaudited)


1.   Basis of Presentation

The unaudited interim financial statements included herein have been prepared by
Midway Airlines Corporation ("Midway" or the "Company"), in accordance with
generally accepted accounting principles ("GAAP") for interim financial
reporting pursuant to the rules and regulations of the Securities and Exchange
Commission. The information furnished in the interim financial statements
includes normal recurring adjustments and reflects all adjustments which, in the
opinion of management, are necessary for a fair presentation of such financial
statements. The results of operations for any interim period presented are not
necessarily indicative of the results to be expected for any other period.
Certain information and footnote disclosures normally included in financial
statements prepared in accordance with GAAP have been condensed or omitted
pursuant to the rules and regulations of the Securities and Exchange Commission,
although the Company believes that the disclosures are adequate to make the
information presented not misleading. These condensed financial statements
should be read in conjunction with the financial statements, and the notes
thereto, included in the Company's Annual Report on Form 10-K for the year ended
December 31, 1998.

2.   Significant Accounting Policies and Other Matters

Use of Estimates and Assumptions

Preparation of financial statements in conformity with GAAP requires management
to make estimates and assumptions that affect the reported amounts of assets and
liabilities at the date of the financial statements and the reported amounts of
revenues and expenses during those reporting periods. Actual results could
differ from those estimates.

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents include investments with an original maturity of three
months or less or which may be redeemed without penalty at any time. These
investments are stated at cost, which approximates market value. As of September
30, 1999 and December 31, 1998, approximately $14.4 million and $9.5 million,
respectively, of cash and cash equivalents were restricted as to withdrawal;
these funds serve as collateral to support letters of credit and a credit card
holdback and are classified as restricted cash in the balance sheets.

Short-term Investments

Short-term investments consist of corporate bonds which mature between three
months and one year of the original investment date. These investments are
carried at cost, which approximates market value.

            three months and the nine months ended September 30, 1999 because
            the exercise price of the options was greater than the average
            market price of the common shares and, therefore, the effect would
            be antidilutive.

4.   Commitments and Contingencies

Purchase Commitments:

As of September 30, 1999, the Company had firm orders to purchase 10 newly
manufactured CRJ-200ER Canadair Regional Jet (CRJ) aircraft, all of which are
scheduled to be delivered by December 2001. Midway also has options to acquire
up to 14 additional CRJ aircraft. The Company has ordered two General Electric
CF34-3B1 spare engines to support the operation of its CRJ aircraft.

The Company has placed firm orders to purchase 15 Boeing 737-700 aircraft, and
has agreed to lease two additional Boeing 737-700s. Deliveries of the two leased
Boeing 737-700 aircraft are scheduled for December 1999 and January 2000, and
deliveries of the other 15 Boeing 737-700 aircraft are scheduled to begin in
September 2000 and end in October 2002. The Company has options to acquire 10
additional Boeing 737-770 aircraft. The Company intends to purchase four CFM
56-7B spare engines to support the operation of its Boeing 737-700 aircraft.

The Boeing purchase agreement requires the Company to make pre-delivery deposits
with respect to each aircraft. The pre-delivery deposits to be made will, in the
aggregate, reach a peak of $117.1 million by August 2000. Thereafter, these
deposits will begin to decrease and monies will be returned to Midway as the
aircraft are delivered. The aircraft manufacturer has agreed to finance a
portion of this obligation at interest. Midway's unfinanced obligation will peak
at about $62.6 million in August of 2000. As of September 30, 1999, Midway had
paid $28.0 million of the pre-delivery deposits and its remaining obligation is
approximately $34.6 million. This obligation is due in monthly installments.
(See Liquidity and Capital Resources).

In March 1995, Midway entered into an agreement for the acquisition of four
Airbus A320 aircraft with deliveries beginning in 1998. The Company also agreed
to purchase one IAE V2527-A5 spare engine to support the operation of the four
A320 aircraft. The delivery dates of these aircraft and the spare engine have
been extended to 2005 and later. The Company is required to make deposits on the
four A320 aircraft
<PAGE>

and the spare engine in amounts to be determined beginning in 2003. The Company
is considering several alternatives with respect to the A320s, including
restructuring its purchase agreement or selling its position.

Other Contingencies:

In the fourth quarter of 1998, the Company retired two Fokker F-100 aircraft at
the expiration of the related lease terms. In each of March and May 1999, the
Company retired one F-100 aircraft at the expiration of the related lease. With
respect to the retirement of these aircraft, the Company and the lessor disagree
as to the amount of certain life cycle costs required to maintain the aircraft
and as to the level of the Company's responsibility to pay for such costs. The
Company believes that it has met or exceeded its obligations. The lessor
believes that the Company has not met its obligations and has brought an action
against the Company alleging breach of contract and unjust enrichment, seeking
damages in excess of $5 million under each claim. The Company believes it has
meritorious legal defenses to the lessor's claims and will vigorously defend the
action, if necessary. At this time, it is not possible to predict the outcome of
this matter.

In August 1998, the Compliance and Enforcement Branch of the Drug Abatement
Division of the Federal Aviation Administration ("FAA") conducted an inspection
of the Company's compliance with certain regulations related to its alcohol and
drug testing programs. In September 1998, the FAA notified the Company that it
was investigating alleged violations discovered during the August 1998
inspection. The Company responded to these alleged violations in October 1998.
In May 1999, the FAA requested that the Company provide the FAA with an update
of certain matters raised during the investigation. The Company promptly
provided this information to the FAA and has received no further communications
from the FAA in this respect. The Company is unable to determine whether the
FAA's investigation will result in the finding of violations of these
regulations and, if so, whether the FAA will pursue an assessment as a result of
any such findings or what the amount of any such assessment might be.

In September 1997, the Civil Aviation Security Division of the Federal Aviation
Administration ("FAA") conducted an investigation of the Company's compliance
with certain regulations requiring the Company to verify the accuracy of the
background information provided by its employees who have access to secure
airport areas. The Company revised its background check procedures during the
course of the FAA's investigation and then obtained and verified the necessary
background information of those employees who had been identified by the FAA as
having insufficient background check documentation. This investigation will
likely result in a finding by the FAA of violations of these regulations. The
Company has received no communications from the FAA in this respect since 1998.

The Company has been named as a defendant in certain pending litigation. The
outcome of these matters cannot be predicted, but it is management's belief that
whatever the outcome, the results will not, either individually or in the
aggregate have a material adverse effect on the Company's financial position,
results of operations or cash flows.

The Company's pilots, fleet service (ramp) agents, and flight attendants are
represented by labor unions. The pilots' representative, the Air Line Pilots
Association ("ALPA"), was elected in December 1997, the ramp employees'
representative, International Association of Machinists and Aerospace Workers,
AFL-CIO ("IAM"), was elected in June 1998, and the flight attendants'
representative, the Association of Flight Attendants, AFL-CIO ("AFA") was
elected in December 1998. Prior to those times, none of the Company's employees
were represented by a union. Although the Company believes mutually acceptable
agreements can be reached with the unions representing such employees,
negotiations have not yet concluded with ALPA, AFA, or the IAM, and the ultimate
outcome of such negotiations cannot be predicted. With respect to the IAM
negotiations, a contract proposal was submitted to the covered employees for
ratification on October 28, 1999 and it was rejected. The IAM filed an
application for mediation with the National Mediation Board ("NMB") on November
3, 1999 and the NMB appointed a mediator on November 8, 1999. Mediation meetings
have not yet been scheduled.

5.   Subsequent Events

On November 8, 1999, the Company announced that it had received a proposal from
two shareholders, Dr. James H. Goodnight and Mr. John P. Sall, under which a
newly formed corporation to be wholly owned by Messrs. Goodnight and Sall would
merge with Midway. In the merger, all shares of Midway stock not owned by
Messrs. Goodnight and Sall would be exchanged for cash at $8.00 per share.

There are approximately 8.6 million shares of Midway common stock outstanding,
of which approximately 4.1 million, or 47.4%, are owned by Goodnight and Sall.
On November 5, 1999, the closing price on the Nasdaq National Market of Midway
common stock was $6.125 per share.

As proposed by Messrs. Goodnight and Sall, the merger would be subject to
execution of an acceptable employment agreement with the Chief Executive Officer
of Midway and any required vote of the outstanding shares of Midway. The
proposal is also subject to negotiation of a merger agreement containing terms
and conditions mutually satisfactory to the parties.

At a meeting of the Company's Board of Directors, the Board appointed Mr.
Gregory J. Robitaille and Mr. Gregory Harding-Brown, independent members of the
Board of Directors of the Company to serve as a special committee of the Board
of Directors in connection with the proposal. The special committee was given
the power and authority to assess the proposal from Messrs. Goodnight and Sall,
to retain advisors as necessary to carry out its responsibilities, and to make a
recommendation to the full Board of Directors with respect to the proposal.

At a subsequent meeting of the Board of Directors, the special committee advised
the Board of Directors that it had met with potential financial and legal
advisors and that it was taking other necessary actions in connection with its
review of the proposal.

Results of Operations

  For the three months ended September 30, 1999 the Company's net income was
$0.2 million, down 90.4% from the net income of $2.4 million for the three
months ended September 30, 1998. Revenue for the three months ended September
30, 1999 was up 0.1% from 1998 to $49.5 million. The Company's operating margin
decreased to 1.6% in 1999 from 8.0% in 1998.
<PAGE>

  Diluted earnings per share for the three months ended September 30, 1999
amounted to $0.02 compared to $0.24 for the three months ended September 30,
1998.

Unusual Items

During September 1999, Hurricanes Floyd and Dennis and two tropical storms
resulted in the cancellation of 5.5 percent of Midway's scheduled flights,
pushing aircraft utilization down, reducing revenue, and resulting in passenger
reaccommodation costs which are included in other operating expenses.
<PAGE>

Capacity. In the three months ended September 30, 1999, the company produced 382
million ASMs, a decrease of 8.0 million or 2.1% over the three months ended
September 30, 1998. The decrease in ASM production is attributable to 24.1%
fewer seats per departure (to 66 seats) partially offset by 25.5% more
departures (to 11,710) and a 2.4% longer average stage length (to 471 miles).
These changes resulted from the change in the Company's fleet (see below) and a
schedule realignment initiated in February 1999.

</TABLE>

Operating Revenues. The Company's operating revenues remained stable at $49.5
million for the three months ended September 30, 1999. Passenger revenue
increased 0.7% due to a 2.4% increase in passenger yield to 19.2 cents partially
offset by a 1.6% decrease in revenue passenger miles to 252 million. Passenger
revenue per ASM increased to 12.7 cents per ASM for the three months ended
September 30, 1999 from 12.36 cents. Cargo revenue decreased due to less mail
being carried partially offset by more cargo being carried, while contract and
other revenue decreased due to a reduction in charter operations partially
offset by ground handling services provided to other airlines in the three
months ended September 30, 1999.

Operating Expenses. The Company's operating expenses increased 7.0% to $48.7
million for the three months ended September 30, 1999 from $45.5 million for the
three months ended September 30, 1998. Operating expenses increased primarily
due to increases in wages, salaries and related costs and aircraft fuel,
partially offset by a reduction in maintenance expense. Operating expense per
ASM increased 9.3% to 12.77 cents from 11.68 cents. This increase is
attributable primarily to an increase in wages, salaries and related costs and
aircraft fuel, partially offset by a decrease in maintenance cost per ASM and
the reduction in ASM production year over year.

  Wages, salaries and related costs increased $1.8 million or 22.4% to $9.8
million for the three months ended September 30, 1999 from $8.0 million for the
three months ended September 30, 1998. The increase is attributable to increased
staffing associated with the addition of the CRJs, increased staffing in
reservations and increased wages per employee, partially offset by a decrease
in the profit sharing expense in the three months ended September 30, 1999
related to the Company's Bonus Plan implemented in 1998. Wages, salaries and
related cost per ASM increased 0.51 cents or 24.9% to 2.56 from 2.05 cents. The
increase in unit costs is attributable to the items noted above as well as the
changes noted in "Capacity".

  Aircraft fuel expense increased 25.3% to $5.9 million for the three months
ended September 30, 1999 from $4.7 million for the three months ended September
30, 1998.  The increase was due to a 27.2% increase in the average fuel price
per gallon to 54.2 cents from 42.6 cents (net of into plane fees and taxes), and
the 27.6% increase in block hours, partially offset by the flying of the lower
fuel burn CRJ aircraft.  Aircraft fuel expense per ASM increased 27.9% to 1.56
cents from 1.22 cents.

  Aircraft and engine rental expense increased 3.9% to $7.6 million for the
three months ended September 30, 1999 from $7.4 million for the three months
ended September 30, 1998.  The increase in expense is attributable to $3.4
million in lease expense in the three months ended September 30, 1999 for leased
CRJs which were placed in service beginning in September 1998, partially offset
by the return at the end of their leases of four F100s and one Airbus A320 (see
Capacity).  Aircraft and engine rentals expense per ASM increased 5.8% to 2.00
cents from 1.89 cents.  The increase in cost per ASM resulted from a combination
of the 2.1% decrease in ASMs discussed above in "Capacity" and the increase in
the number of aircraft under lease.


  Commission expense remained stable at $3.2 million for the three months ended
September 30, 1999. This was due to a reduction in the commission rate paid and
a decrease of travel agency revenues as a percent of passenger revenue to 63.2%
from 63.4%, partially offset by the 0.7% increase in passenger revenues.
Commissions expense per ASM increased 3.7% to 0.85 cents from 0.82 cents,
primarily driven by the reduction in capacity operated.


  Maintenance, materials and repairs expense decreased 22.1% to $3.0 million for
the three months ended September 30, 1999 from $3.9 million for the three months
ended September 30, 1998.  The expense decrease is largely attributable to the
new maintenance contracts on most of the Company's F100 aircraft, the retirement
of 4 Fokker F100 aircraft and the A320, and the lower maintenance cost of the
new CRJ fleet, offset somewhat by the 27.6% increase in block hours.
Maintenance, materials and repairs expense per ASM decreased 20.2% to 0.79 cents
from 0.99 cents due to the changes noted above.

  Other rentals and landing fees expense increased 2.1% to $2.5 million for the
three months ended September 30, 1999 from $2.4 million for the three months
ended September 30, 1998. The expense increase is attributable primarily to
25.5% more departures and by new facility rentals, partially offset by lower
landing fee rates at the Company's hub, and the shift in the fleet mix,
resulting in 187% more CRJ landings and 40% fewer landings by the larger Fokker
and Airbus aircraft. Other rentals and landing fees expense per ASM increased
4.8% to 0.65 cents from 0.62 cents.

  Depreciation and amortization expense decreased 2.0% to $1.7 million for the
three months ended September 30, 1999 from $1.8 million for the three months
ended September 30, 1998.  Depreciation and amortization expense per ASM
remained stable at 0.45 cents.

  Other operating expense increased 5.2% to $14.9 million for the three months
ended September 30, 1999 from $14.2 million for the three months ended September
30, 1998. Other operating expenses consist primarily of reservations, ground
handling, advertising, crew overnight accommodations and training, general and
administrative expense and insurance. The expense increase is attributable to
the 25.5% increase in departures, and crew accommodations and training,
partially offset by savings in insurance,
<PAGE>

outside reservation services, and marketing and administrative expenses and the
1.2% decrease in passengers. Other operating expense per ASM increased 7.4% to
3.91 cents from 3.64 cents.

(1)   Excludes equipment retirement charges
(2)   Excludes taxes and into-plane fees

For the nine months ended September 30, 1999 the Company's net income was $8.2
million. Excluding the equipment retirement charges discussed below, net income
was $9.5 million (net of taxes), down 17.7% from the net income of $11.5 million
for the nine months ended September 30, 1998. Revenue for the nine months ended
September 30, 1999 was up 2.8% over 1998 to $160.0 million. Excluding the
equipment retirement charges the Company's operating margin decreased to 10.7%
in 1999 from 12.8% in 1998.

Diluted earnings per share for the nine months ended September 30, 1999 amounted
to $0.86 ($0.99 excluding unusual items) compared to $1.18 for the nine months
ended September 30, 1998.

Unusual Items

  During September 1999, Hurricanes Floyd and Dennis and two tropical storms
resulted in the cancellation of 5.5 percent of Midway's scheduled flights,
pushing aircraft utilization down, reducing revenue, and resulting in passenger
reaccommodation costs.

  During the nine months ended September 30, 1999 the Company incurred $2.0
million in equipment retirement charges related to the retirement of three
aircraft, one of which left the fleet in March, one in May and one in June.

  Additionally, during the first six months of 1999 the Company incurred added
cost and reduced revenue due to a shortage of pilots driven by a tripling of the
normal pilot attrition rate and pilot absenteeism due to illness during that
period. Attrition, which was up due to increased hiring by the major carriers,
and the increased absence from sick calls had the effect of forcing the
cancellation of one aircraft's worth of
<PAGE>

capacity throughout the six months ended June 30, 1999. Increased hiring and a
reduction in pilot attrition have since reduced the pilot shortage.

Capacity.  In the nine months ended September 30, 1999, the Company produced
1,133 million ASMs, a decrease of  17.8 million or 1.5% over the nine months
ended September 30, 1998.  The decrease in ASM production is attributable to a
1.9% shorter average stage length (to 470 miles) and 22.2% fewer seats per
departure (to 70 seats) partially offset by 27.4% more departures (to 32,978).
These changes resulted from the change in the Company's fleet, (decreasing the
number of 98-seat F100s to eight during the nine months ended September 30,
1999, the 148-seat A320 being out of service for two months in the first quarter
and being removed from service in May and returned at the expiration of its
lease in June, 1999, and an increase in the number of 50-seat CRJs to 16), the
pilot shortage noted above, the hurricanes, and a schedule realignment initiated
in February 1999.

Operating Revenues. The Company's operating revenues increased 2.8% to $160.0
million for the nine months ended September 30, 1999 from $155.7 million for the
nine months ended September 30, 1998. Passenger revenue increased 3.4% due to a
4.4% increase in passenger yield (revenue per RPM) to 21.1 cents partially
offset by a 1.0% decrease in revenue passenger miles to 742.5 million. Passenger
revenue per ASM increased 5.0% to 13.8 cents per ASM due to the 4.4% increase in
yield combined with a 0.4 percentage point increase in load factor to 65.6%.
Cargo revenue decreased due to less mail being carried partially offset by more
cargo being carried, while contract and other revenue decreased due to a
reduction in charter operations, partially offset by ground handling services
provided to other airlines in the nine months ended September 30, 1999.

Operating Expenses. The Company's operating expenses increased 6.8% to $144.9
million for the nine months ended September 30, 1999 from $135.7 million for the
nine months ended September 30, 1998. Total expenses increased primarily due to
increases in wages, salaries and related costs, depreciation and amortization,
other miscellaneous operating expenses, and equipment retirement charges,
partially offset by a reduction in fuel cost per gallon, lower commission
expense, and lower maintenance expense. Operating expense per ASM increased 8.3%
to 12.79 cents from 11.80 cents. This increase is attributable to an increase in
depreciation and amortization expense related to the ownership of five CRJs and
the parts for the fleet, equipment retirement charges, and an increase in other
expenses and the reduction in ASM production year over year.

  Wages, salaries and related costs increased $4.8 million or 20.5% to $28.4
million for the nine months ended September 30, 1999 from $23.6 million for the
nine months ended September 30, 1998.  The increase is attributable to increased
staffing associated with the addition of the CRJs and the increased number of
stations and flights, increased wages per employee, partially offset by a
decreased profit sharing expense in the nine months ended September 30, 1999
related to the Company's Bonus Plan implemented in 1998.  Wages, salaries and
related cost per ASM increased 0.46 cents or 22.4% to 2.51 cents.  The increase
in unit costs is attributable to the items noted above as well as the changes
noted in "Capacity".

  Aircraft fuel expense remained stable at $14.7 million for the nine months
ended September 30, 1999. Aircraft fuel expense per ASM increased 1.6% to 1.30
cents from 1.28 cents.

  Aircraft and engine rental expense increased 1.2% to $22.4 million for the
nine months ended September 30, 1999 from $22.1 million for the nine months
ended September 30, 1998. The increase resulted from the change in the fleet mix
year over year (see Capacity). Aircraft engine rentals expense per ASM increased
2.6% to 1.97 cents from 1.92 cents.

  Commission expense decreased 7.3% to $10.5 million for the nine months ended
September 30 1999 from $11.4 million  for the nine months ended September 30,
1998.  This was due to a reduction in the commission rate paid and a decrease of
travel agency revenues as a percent of passenger revenue to 64.1% from 66.5%,
partially offset by the 3.4% increase in passenger revenues.  Commissions
expense per ASM decreased 6.1% to 0.93 cents from 0.99 cents, primarily driven
by the reduction in the commission rate paid and the decrease in agency
revenues.

  Maintenance, materials and repairs expense decreased 18.3% to $9.8 million for
the nine months ended September 30, 1999 from $12.0 million for the nine months
ended September 30, 1998.  The expense decrease is largely attributable to the
new maintenance contracts on most of the Company's F100 aircraft, and the
retirement of 4 Fokker F100 and one A320 aircraft and lower maintenance costs
for the new CRJ fleet, offset somewhat by the 25.7% increase in block hours.
Maintenance, materials and repairs expense per ASM decreased 16.4% to 0.87 cents
from 1.04 cents.

<PAGE>

  Other rentals and landing fees expense increased 2.8% to $7.4 million for the
nine months ended September 30, 1999 from $7.2 million for the nine months ended
September 30, 1998. The expense increase is attributable primarily to 27.4% more
departures and facility rentals in newly opened stations and the new
headquarters facility in Morrisville, North Carolina, partially offset by lower
landing fee rates at the Company's hub, the shift in the fleet mix, resulting in
230% more CRJ landings and 33% fewer landings by the larger Fokker and Airbus
aircraft. Other rentals and landing fees expense per ASM increased 3.2% to 0.65
cents from 0.63 cents.

  Depreciation and amortization expense increased 23.4% to $5.3 million for the
nine months ended September 30, 1999 from $4.3 million for the nine months ended
September 30, 1998. Depreciation and amortization expense per ASM increased
27.0% to 0.47 cents from 0.37 cents in the nine months ended September 30, 1998.
The increase is attributable to the acquisition of five owned CRJs and related
spare parts.

  Other operating expense increased 9.6% to $44.3 million for the nine months
ended September 30, 1999 from $40.4 million for the nine months ended September
30, 1998. Other operating expenses consist primarily of reservations, ground
handling, advertising, general and administrative expense and insurance. The
expense increase is attributable to the 27.4% increase in departures and the
0.8% increase in passengers, partially offset by savings in insurance, marketing
and administrative expenses. Other operating expense per ASM increased 11.1% to
3.91 cents from 3.52 cents.

Liquidity and Capital Resources

Liquidity
- ---------

  The Company's working capital decreased during the nine months ended September
30, 1999 compared to the year ended December 31, 1998. As of September 30, 1999,
the Company had cash, restricted cash, and short-term investments of $33.9
million and working capital deficit of $5.9 million compared to $58.2 million
and $32.9 million respectively as of December 31, 1998. The decrease in working
capital is due primarily to the net increase in aircraft purchase deposits of
$27.6 million and the increase in advanced ticket sales of $9.5 million. During
the nine months ended September 30, 1999, cash, restricted cash and short-term
investments decreased $24.3 million, reflecting net cash provided by operating
activities of $18.9 million (net of changes in restricted cash), net cash used
in investing activities of $38.6 million (net of purchases and sales of short
term investments), and net cash used in financing activities of $4.6 million.
During the nine months ended September 30, 1999, net cash provided by operating
activities was primarily due to net income and advance ticket sales partially
offset by the increase in aircraft lease deposits and other; net cash used in
investing activities was due to net payments of equipment purchase deposits and
purchases of equipment and property; and net cash used in financing activities
reflects repayment of long-term debt and capital lease obligations.

Capital Resources
- -----------------

The Company's aircraft purchase obligations amount to approximately $565
million. The Company's remaining pre-delivery deposit obligations amount to
approximately $34 million. The Company's anticipated near-term, non-aircraft
capital expenditures amount to approximately $20 million. Together, these
obligations exceed the Company's internal capital resources and accordingly, the
Company will be required to obtain capital from external sources. A substantial
portion of the required external capital has been committed to the Company by
the aircraft and engine manufacturers, subject to satisfaction of certain
conditions. The Company is diligently pursuing financing for the remaining
unfunded obligations although no assurances can be given that such financing
will be available on a timely basis. To the extent financing can not be obtained
timely, the Company's liquidity and capital resources will be adversely
affected.


Capital Expenditures
- --------------------

  The Company's cash outflows for capital expenditures in the nine months ended
September 30, 1999 and 1998 were $10.9 million and $6.0 million, respectively,
excluding financed purchases.

<PAGE>

  The Company has in place firm orders to purchase 10 additional newly
manufactured CRJ-200ER Canadair Regional Jet aircraft, all of which are
scheduled to be delivered by December 2001.  Midway also has options to acquire
up to 14 additional CRJs.  The Company has ordered two General Electric CF34-3B1
spare engines to support the operation of its CRJ aircraft.

  The Company has placed firm orders to purchase 15 Boeing 737-700 aircraft, and
has leased two additional Boeing 737-700s. Deliveries of the two leased Boeing
737-700 aircraft are scheduled for December 1999 and January 2000, and delivery
for the other 15 Boeing 737-700 aircraft are scheduled to begin in September
2000 and end in October 2002.  The Company has options to acquire 10 additional
Boeing 737-700s.  The Company intends to purchase four CFM 56-7B spare engines
to support the operation of its Boeing 737-700 aircraft.

  The Company's fixed costs will increase significantly with the induction of
the new CRJs and the 737-700s.  Based on the current interest rate environment,
the Company estimates that its fixed charges will increase by approximately $9.2
million over the next twelve months as a result of the financing of the aircraft
to be delivered during that time.  However, depending upon the financing method
ultimately chosen, the Company's balance sheet liabilities may or may not
increase.

Year 2000

State of Readiness

  The Company's Year 2000 Project was designed to ensure that the Company's
computer systems and embedded operating systems will function properly beyond
1999.  The Project involved five phases:  Inventory, Assessment, Remediation,
Testing and Contingency Planning.

  During the Inventory Phase, the Company identified six business-critical
functions which rely heavily on computer or embedded systems for safe or
reliable operations.  These six functions include the operation of aircraft,
the operation of the Company's computer reservation system and related telephone
systems, the transmission and reconciliation of credit card and travel agency
sales and collection of money, the operation of the Company's yield management
systems, the operation of the Company's aircraft dispatch and air traffic
control systems as they communicate with the FAA's air traffic controllers and
other agencies and the utilization of certain time-sensitive crew qualification
and tracking systems, and aircraft maintenance control and planning systems.

  The Company has completed the Assessment Phase which first began with a
detailed review of these six critical functions and the applicable systems used
by the Company or its vendors in performing these functions.  This review has
concluded and the results were as follows:

     .    With respect to its aircraft, the Company has received assurances and
          warranties that the embedded technology in such aircraft and parts
          will process date data correctly in the Year 2000. The manufacturers
          and suppliers of these aircraft and parts have provided the Company
          with regular updates of their investigation and testing of the
          component systems for Year 2000 compliance. To date, the information
          provided by these sources has not identified any aircraft or parts in
          the Company's projected Year 2000 fleet which are not now Year 2000
          compliant.

     .    With respect to its yield management systems and its computer
          reservation system, each of these systems is operated and maintained
          by American Airlines, Inc. and/or its affiliate, SABRE Group Holdings,
          Inc. The SABRE Group Holdings, Inc. has stated that the computer
          reservation system is now Year 2000 compliant, with only testing of
          minor sub-systems remaining to be completed. The Company's computer
          reservation system has, in fact, begun taking reservations for travel
          in the Year 2000. The SABRE Group has also stated that

<PAGE>

          substantially all of its core systems are either completed or in the
          final testing phases of its Year 2000 Project.

     .    With respect to its telephone systems, the Company has installed and
          is using a new phone switch and related systems/equipment in its
          headquarters and reservations center. The phone switch and related
          systems/equipment have been warranted as Year 2000 compliant by the
          seller, a leading communications technology company.

     .    With respect to the systems used in the transmission and
          reconciliation of credit card sales, the Company is reliant upon the
          systems of the credit card companies, the systems used by these
          companies to transact business with their customers' banks and the
          systems used by the Company's revenue accounting vendor. The Company
          has received written assurances from its revenue accounting vendor
          that its systems are Year 2000 compliant and that it successfully
          completed Year 2000 testing in September 1998. The Company has
          reviewed information made available by the credit card companies (such
          as MasterCard and American Express) and these companies have stated
          that card members should not experience any problems using cards with
          expiration dates of the Year 2000 or beyond.

     .    With respect to its primary maintenance control and planning system,
          the Company had previously determined that this system was not Year
          2000 compliant. The Company and its third party consultants have
          completed remediation and testing of this system and it is currently
          being used to tracking maintenance tasks in the Year 2000. The Company
          has developed a contingency plan to utilize in the event that the
          current system fails to be Year 2000 compliant. With respect to its
          crew qualification and tracking systems, the vendor has warranted the
          systems are Year 2000 compliant when operated on an appropriate
          platform. The Company has been using these systems on its current
          platform and the systems are properly recording Year 2000 events.

     .    With respect to the Company's aircraft dispatch and related air
          traffic control systems, the Company is largely dependent upon the
          systems operated by certain governmental entities such as the FAA that
          provide the aviation industry with critical information and reports.
          The Company is reviewing and will continue to review the Year 2000
          information and readiness reports issued by these entities. The FAA
          asserts that its systems are Y2K compliant, although the Company has
          no independent method to verify this assertion.

  In summary, the Company identified the computer systems which support its
business-critical functions and has taken necessary remedial actions to address
Year 2000 problems identified during the review of these systems and which could
be addressed within the Company's own systems and facilities.  As part of its
Remediation and Testing Phases, the Company continues to review Year 2000
information and reports issued by its vendors and other third parties as they
relate to business critical (and other) functions in order to respond to systems
information or changes that could affect the Company's Year 2000 readiness.

  During the Inventory Phase, the Company also identified a number of other
Company functions which require the use of computer systems for operation, but
which are not business-critical.  These functions include the preparation of
financial books and records, the scheduling of crew and aircraft, the processing
of payroll and similar functions.  The Company has completed its Year 2000
remediation efforts with respect to these systems.

  The Company's System-Testing Phase has been completed and the Company has
verified successful testing of third party systems, or has otherwise completed
testing with respect to its business-critical functions. With respect to third
party computer systems which support other functions, the Company has limited or
no ability to independently test the systems of third parties which support
these operations and must rely on testing completed and reported by these third
parties. To the extent possible, testing of the systems which support these
operations will be completed in a timely manner.

<PAGE>

  Although the Contingency Planning Phase of the Company's Year 2000 Project has
concluded in a number of select areas, it has not yet been fully completed.  The
Company believes that most of its business-critical and other functions can be
performed manually or without aid of computer systems (such as scheduling of
crew and aircraft and revenue collection processes), but that the performance of
these functions will obviously be materially impacted should certain systems
fail to operate past 1999.  To the extent reasonably possible, the Company
intends to develop contingency plans to ensure continued operations in the event
certain systems fail to operate after 1999.

  The Company has completed the Remediation and Testing Phases, and intends
to complete the Contingency Planning phase and believes it is prepared, to the
fullest extent possible, for the Year 2000 cut-over.

  Separately, the Federal Aviation Authority Year 2000 Program Office required
the Company to supply the agency with materials related its Year 2000 Project.
The FAA year 2000 Program Office has reviewed these materials, with additional
information from the FAA Flights Standards Service organization, and informed
the Company that it has been assigned a category 1 rating for Year 2000
readiness.

A category 1 definition is:

    "Most available information regarding this airline indicates that a
    comprehensive and thorough program to attempt to identify and correct
    potential aviation-related Y2K problems has been implemented. While there is
    no guarantee that Y2K-related problems will not occur, the probability of
    numerous, lengthy or severe Y2K-related disruptions of airline operation is
    anticipated to be low. This statement is based primarily upon self-reported
    information not subject to independent Department of Transportation
    verification."

Costs of Compliance:
- --------------------

  The total costs of the Company's Year 2000 Project were immaterial and were
funded from available cash balances. To date, the Company has incurred less than
$100,000 in connection with the Project, all of which has been expensed as
incurred. The cost of the Company's Year 2000 Project is limited by the
substantial outsourcing of its systems, the relative youth of the Company and
its operating systems and the purchase of new technology.

Risks of Non-Compliance:
- ------------------------

  The Company believes that the Year 2000 issue will not pose significant
operational problems for its computer systems. However, there can be no
assurance that the systems of third parties on which the Company's business
relies (including those of its customers, its vendors or the FAA) will be
modified on a timely basis. The Company's business, financial condition or
results of operations could be materially adversely affected by the failure of
its systems or those operated by other parties to operate properly beyond 1999.
To the extent reasonably possible, the Company will continue developing and
executing

<PAGE>

contingency plans designed to allow continued operation in the event of the
failure of the systems of the Company or certain third parties. These
contingency plans have not yet been fully established.

Forward-Looking Statements
- --------------------------

  The Private Securities Litigation Reform Act of 1995 (the Act) provides a safe
harbor for forward-looking statements made by or on behalf of the Company.  The
Company and its representatives may from time to time make written or verbal
forward-looking statements, including statements contained in the Company's
filings with the Securities and Exchange Commission and in reports to share
owners.  All statements which address operational performance, events or
developments which are anticipated to occur in the future, including statements
relating to revenue growth, cost reductions and earnings growth or statements
expressing general optimism about future operating results, are forward-looking
statements within the meaning of the Act.  The forward-looking statements are
and will be based on management's then current views and assumptions regarding
future events and operating performance.

  Some of the factors that could cause actual results to differ materially from
estimates contained in the Company's forward-looking statements include the
following:

 .  The ability to generate sufficient cash flows to support capital expansion
   plans and general operating activities.

 .  Change in laws and regulations, including changes in accounting standards,
   taxation requirements (including tax rate changes, new tax laws and revised
   tax law interpretations) and environmental laws.

 .  Fluctuations in the cost and availability of materials, fuel, equipment and
   labor, including the continued availability of landing slots at New
   York/LaGuardia and Washington Reagan airports.

 .  The ability to achieve earnings forecasts, which are based on projected
   Traffic and fares in the different markets the Company serves, some of which
   are more profitable than others.

 .  Interest rate fluctuations and other capital market conditions.

 .  The reliance on a limited number of markets and the ability to enter and
   develop new markets.

 .  The effectiveness and availability of resources to support advertising,
   marketing, and promotional programs.

 .  The impact of increased competition in the Raleigh-Durham market on fares,
   traffic, new market opportunities and related matters.

 .  The uncertainties of litigation and/or administrative proceedings.

 .  Adverse weather conditions, which could affect the Company's ability to
   operate.

 .  The Company's significant dependence on the Raleigh Durham market.

 .  Control by existing stockholders, and the proposal to acquire the Company.

 .  The Company's indebtedness (including capital and operating lease
   obligations).

PART II.  Other Information

Item 1.   Legal Proceedings.

In the fourth quarter of 1998, the Company retired two Fokker F-100 aircraft at
the expiration of the related lease terms.  In each of March and May 1999, the
Company retired one F-100 aircraft at the expiration of the related lease.  With
respect to the retirement of these aircraft, the Company and the lessor disagree
as to the amount of certain life cycle costs required to maintain the aircraft
and as to the level of the Company's responsibility to pay for such costs.  The
Company believes that it has met or exceeded its obligations.  The lessor
believes that the Company has not met its obligations and has brought an action

<PAGE>

against the Company alleging breach of contract and unjust enrichment, seeking
damages in excess of $5 million under each claim.  The Company believes it has
meritorious legal defenses to the lessor's claims and will vigorously defend the
action, if necessary.  At this time, it is not possible to predict the outcome
of this matter.

  The Company has been named as a defendent (along with the members of its Board
of Directors and Messrs. Goodnight and Sall) in a class action complaint filed
on November 8, 1999 in Delaware State Chancery Court. The complaint was filed in
response to the merger proposed made by Messrs. Goodnight and Sall and alleges
that the consideration is unfair and inadequate and that the proposal serves no
legitimate business purpose, among other things. The Company will review the
matter with counsel and defend the claims brought against the Company.

  The Company is otherwise a party to routine litigation incidental to its
business.  Management believes that none of this litigation is likely to have a
material adverse effect on the Company's financial position or results of
operations.

ITEM 3.  Quantitative and Qualitative Disclosures about Market Risk:

The Company's financial results and cash flows are subject to fluctuation due to
changes in interest rates primarily from its investment of available cash
balances in highly rated institutions. Current policies do not allow it to use
interest rate derivative instruments to manage exposure to interest rate
changes. The Company does not expect its operating results or cash flows to be
affected to any significant degree by a sudden change in market interest rates.

ITEM 4.  Submission of Matters to a Vote of Security Holders.

None

ITEM 5.  Other Information.

On November 8, 1999, the Company announced that it had received a merger
proposal from two shareholders, Dr. James H. Goodnight and Mr. John P. Sall.
(See Notes to Financial Statements, Subsequent Events).

On November 11, 1999, Howard Wolf, a senior partner at Fulbright and Jaworski
resigned his position as a member of Midway's Board of Directors.

                  SALE, LEASING AND SECURED LOAN TRANSACTIONS

          Section 2.01. Participation.  Subject to all of the terms and
                        -------------
conditions of this Agreement, the parties agree to participate in the sale,
leasing and secured loan transactions with respect to the Aircraft provided for
in this Section 2.

          (a) Sale and Purchase.  The Owner Trustee agrees to purchase the
              -----------------
Aircraft from the Seller on the Delivery Date for a purchase price equal to
Lessor's Cost.

          (b) Leasing.  The Owner Trustee agrees to lease to the Lessee, and the
              -------
Lessee agrees to lease from the Owner Trustee, the Aircraft pursuant to the
Lease, such leasing to take place concurrently with the purchase of the Aircraft
by the Owner Trustee on the Delivery Date.

          (c) Owner Participant's Equity Investment.  The Owner Participant
              -------------------------------------
agrees to provide immediately available funds in the amount determined by
multiplying Lessor's Cost by the percentage set forth opposite its name on
Schedule I (the Owner Participant's "Commitment") (i) by paying such amount to
the Owner Trustee prior to the time of closing on the Delivery Date at the
account specified by the Owner Trustee on or prior to the Delivery Date, such
amount to be held and applied toward the Owner Trustee's payment of Lessor's
Cost for the Aircraft on the Delivery Date (and if not so applied, to be
promptly returned to the Owner Participant) or (ii) by paying such amount at the
time of the closing on the Delivery Date directly to the Seller's account
specified by the Lessee prior to the closing to be applied toward the payment of
Lessor's Cost.  Such funds, once so applied, shall constitute an equity
investment by the Owner Participant in the Trust Estate, provided that the Owner
                                                         --------
Participant shall have no obligation to provide its Commitment after August 31,
1999.

          (d) Secured Loan.  The Loan Participant agrees to provide immediately
              ------------
available funds in the amount determined by multiplying Lessor's Cost by the
percentage set forth opposite its name on Schedule I (the Loan Participant's
"Commitment") to or on behalf of the Owner Trustee by paying or causing to be
paid such amount to the Owner Trustee, at the account specified by the Owner
Trustee on or prior to the Delivery Date, such amount to be held and applied
toward the Owner Trustee's payment of Lessor's Cost for the Aircraft on the
Delivery Date (and if not so applied, to be promptly returned to the Loan
Participant), provided that the Loan Participant shall have no obligation to
              --------
provide its Commitment after January 31, 2000.  Such funds, once so applied,
shall constitute a loan to the Owner Trustee to be evidenced by an Equipment
Note substantially in the form set forth in the Indenture and as more
particularly described herein and in the Indenture and secured as provided in
the Indenture.

          (e) Delivery Date.  The "Delivery Date" shall be the date fixed by the
              -------------
Lessee in accordance with this Section 2.01(e) for the closing of the sale,
leasing and loan transactions with respect to the Aircraft contemplated hereby,
except that following such closing the "Delivery Date" shall mean the date on
which such transactions actually closed.  The Lessee shall give at least two

                                       3
<PAGE>

Business Days' notice to each other party hereto of the Delivery Date, which
notice shall also specify the amount of the Owner Participant's Commitment and
the Loan Participant's Commitment.  The Lessee may postpone a scheduled Delivery
Date from time to time, for any reason by notice given to the other parties
hereto not later than 2:00 p.m. on the date last scheduled as the Delivery Date,
such notice to specify a new Delivery Date.  In the event that a Participant
shall have provided the amount of its Commitment to the Owner Trustee prior to
such a postponement, the Owner Trustee shall return such amount to such
Participant by 2:00 p.m. on the scheduled Delivery Date unless such Participant
shall have agreed otherwise in writing.  Absent such an agreement, in the event
that the Owner Participant's Commitment is not returned to the Owner Participant
by 2:00 p.m. on a scheduled Delivery Date on which the closing does not occur,
the Lessee shall pay interest to the Owner Participant at a rate equal to the
rate per annum announced from time to time by Citibank, N.A. as its prime rate
plus two percent (2%) per annum for each day that such commitment is not
returned to the Owner Participant by 2:00 p.m..  The making available by the
Owner Participant of its Commitment at the closing shall be deemed a waiver of
notice of the Delivery Date by the Owner Participant and the Owner Trustee, and
the making available by the Loan Participant of its Commitment at the closing
shall be deemed a waiver of notice of the Delivery Date by the Loan Participant
and the Indenture Trustee.

          Section 2.02.  Closing Procedure.
                         -----------------

          (a) Time and Place.  The closing shall take place at 11:00 a.m. New
              --------------
York City local time on the Delivery Date at the offices of Fulbright & Jaworski
L.L.P., 666 Fifth Avenue, New York, New York or at such other time and place as
the parties may agree.  The closing shall be preceded by a pre-closing at the
same place, the time for which shall be fixed by the Lessee, at which the forms
of the Operative Agreements to be executed, the certificates and other documents
to be delivered and the forms of the legal opinions to be delivered at the
closing by each party or its counsel pursuant to this Agreement shall be
available for inspection by the parties and their respective counsel.

              ----------------------------
Trustee of the Commitment of each Participant together with instructions (which
may be oral) from each Participant or its special counsel that the applicable
conditions precedent set forth in Section 3.01 have been satisfied or waived by

due registration of the Aircraft with the FAA in the name of the Owner Trustee
and to file and perfect the security interest of the Indenture Trustee in all or
any part of the Indenture Estate.

          (c) Actions of the Lessee.  Upon satisfaction or waiver by the Lessee
              ---------------------

Delivery Date sell the Aircraft (or cause the Aircraft to be sold) to the Owner
Trustee, lease the Aircraft from the Owner Trustee pursuant to the Lease, assign

Owner Trustee timely notice of the necessity of such action, together with such
instruments, in execution form, and such other information as may be required to
enable either of them to take such action, at the Lessee's cost and expense, in
a timely manner.

Trustee (provided, that the Owner Trustee and the Owner Participant shall be and
         --------
remain Citizens of the United States), under the Transportation Code, and shall
furnish to the Owner Trustee such information as may be required to enable the
Owner Trustee to make application for such registration; provided, however, that
                                                         --------  -------
the Lessee may at any time cause the Aircraft to be appropriately re-registered
under the laws of a country with which at the time of such registration the
United States maintains normal diplomatic relations and is listed on Exhibit E
to the Lease; provided that prior to any change in the country of registry of
              --------
the Aircraft the following conditions are met:

              (i)   at the time of re-registration, no Specified Default exists
     or would occur as a result of such re-registration;

              (ii)  the Lessee shall pay all fees and expenses, recording and
     registration taxes (including the reasonable fees and expenses of local
     counsel in such country) relating to such re-registration or proposed re-
     registration;

              (iii) the Lessee shall, at its cost, cause the interest of the
     Owner Trustee as owner of the Aircraft and the Indenture Trustee as
     mortgagee thereof to be duly registered or recorded under the laws of such
     country and at all times thereafter to remain so duly registered or
     recorded unless and until the registration of the Aircraft is changed as
     provided herein, and shall, at its cost, cause to be done at all times all
     other acts including the filing, recording and delivery of any document or
     instrument and the payment of any sum necessary or, by reference to prudent
     industry practice in such country, advisable in order to create, preserve
     and protect such interest in the Aircraft (including the first priority
     duly perfected Lien under the Indenture) as against the Lessee or any third
     parties in such jurisdiction, and the laws of such country would give
     effect to the Owner Trustee's title to and ownership interest in the
     Aircraft and the Lien of the Indenture Trustee thereon;

              (iv)  the obligations of the Lessee (and of the Permitted
     Sublessee under a Sublease) and each other party under the Operative
     Agreements and the rights and remedies of the Lessor, the Owner
     Participant, the Indenture Trustee and the Noteholders under the Operative
     Agreements shall remain or be, as the case may be, legal, valid, binding
     and enforceable under the laws of such country;

              (v)   the Lessee shall ensure that all insurance required by
     Section 9 of the Lease shall be in full force and effect prior to, at the
     time of, and after such change in registration and the Owner Participant,
     the Owner Trustee, and the Indenture Trustee shall receive a certificate of
     Lessee's insurance broker to such effect;

              (vi)  the country of such re-registration imposes aircraft
     maintenance standards approved by, or at least as stringent as those
     approved by, the FAA or the central civil aviation authority of the United
     Kingdom, France, Germany, Japan, the Netherlands or Canada;

                                      18
<PAGE>

              (vii)  it shall not be necessary by reason of such re-registration
     or for purposes of exercising rights or enforcing remedies contained in the
     Lease or the Indenture or the related Sublease or other Operative
     Agreements for the Owner Trustee, the Indenture Trustee, the Owner
     Participant or any Noteholder to register or qualify to do business in such
     country;

              (viii) no Liens (except Permitted Liens) shall arise by reason of
     such re-registration, and the Indenture shall continue as a valid and duly
     perfected (to the extent relevant in the applicable jurisdiction) first
     priority Lien on the collateral thereunder (subject only to Permitted
     Liens);

              (ix)   none of the Owner Trustee, the Indenture Trustee, the Owner
     Participant and the Noteholders shall be subjected to any risk of adverse
     tax consequences as a result of such re-registration for which the Lessee
     does not then indemnify or cause to be indemnified such Person in a manner
     satisfactory in form and substance to such Person;

              (x)    any export licenses and certificate of deregistration
     required in connection with any repossession or return of the Aircraft will
     be readily obtainable in the normal course without material delay or
     material burden on the Owner Trustee, the Indenture Trustee or the
     Participants, it being agreed that the Lessee shall be responsible for the
     cost thereof and (if not contrary to the Applicable Laws of such country)
     the Indenture Trustee (or, if the Indenture shall have been satisfied and
     discharged in accordance with its terms, the Owner Trustee) will be granted
     a deregistration power of attorney by the Lessee and the Permitted
     Sublessee;

              (xi)   there is no tort liability of the owner or lessor of an
     aircraft not in possession thereof under the laws of such jurisdiction more
     onerous than under the laws of the United States or any state thereof (it
     being agreed that, in the event such opinion cannot be given in a form
     satisfactory to each Participant, such opinion shall be waived if insurance
     reasonably satisfactory to each Participant is provided to cover such
     risk);

              (xii)  unless Lessee shall have agreed to provide insurance
     reasonably satisfactory to the Participants covering the risk of
     requisition of use of or title to the Aircraft by the government of such
     country (so long as the Aircraft is registered under the laws of such
     country), the laws of such country require fair compensation by the
     government of such country payable in currency freely convertible into
     Dollars and freely removable from such country (without license or permit,
     unless Lessee prior to such proposed reregistration has obtained such
     license or permit or such license or permit will be readily obtainable in
     the normal course without material delay or material burden on the
     Participants) for the taking or requisition by such government of such use
     or title;

              (xiii) the courts of such proposed country of registry will
     respect the choice of New York law to govern the Lease;

                                      19
<PAGE>

              (xiv)   such re-registration may not be affected until after
     December 31, 2006 unless the Lessee prepays on a lump sum basis any
     liability due under the Tax Indemnity Agreement as a result of such re-
     registration;

              (xv)    there exist no possessory rights in favor of the Lessee
     (or any Permitted Sublessee) or any third party including any government or
     instrumentality thereof, which would, upon bankruptcy or insolvency of or
     other default by the Lessee and assuming that at such time such Permitted
     Sublessee or third party is not insolvent or bankrupt, prevent the return
     or repossession of the Aircraft in accordance with and when permitted by
     the terms of Section 17(a) of the Lease upon the exercise by Owner Trustee
     (or the Indenture Trustee, as assignee of the Owner Trustee) of its
     remedies under Section 17(a) of the Lease;

              (xvi)   the Owner Participant, the Owner Trustee, the Indenture
     Trustee and the Loan Participants shall have received opinions in scope,
     form and substance reasonably satisfactory to them, of counsel, expert in
     the laws of such country, to the effect set forth in clauses (iii), (iv),
     (vii), (ix), (x), (xi), (xii), (xiii) and (xv) of this Section 4.02(b);

              (xvii)  such proposed change in registration is made in connection
     with a Sublease to a Permitted Air Carrier and such Permitted Sublessee is
     domiciled in such country;

              (xviii) Lessee shall deliver such request to Indenture Trustee,
     Owner Trustee and Owner Participant in writing at least 30 days in advance
     of the date of any such proposed change in registration;

              (xix)   the Deficiency Agreement and the Residual Agreement shall
     remain in full force and effect.

Lessee agrees to pay on an After Tax Basis all reasonable out-of-pocket costs
and expenses (including, without limitation, reasonable counsel fees and
disbursements) of the Owner Participant, the Owner Trustee, the Indenture
Trustee and the Loan Participant in connection with any re-registration pursuant
to this Section.

              (c) Information.  The Lessee shall promptly furnish to the Owner
                  -----------
Trustee and the Owner Participant such information as may be required to enable
the Owner Trustee and the Owner Participant timely to file any reports required
to be filed by the Owner Trustee as the Lessor and the Owner Participant under
the Lease with any governmental authority as a result of the Owner Trustee's
ownership interest in the Aircraft.

              (d) Corporate Existence.  The Lessee shall at all times maintain
                  -------------------
its corporate existence, except as permitted by Section 4.02(e) hereof, and it
shall do or cause to be done all things necessary to preserve and keep in full
force and effect all of its corporate rights, powers, privileges and franchises
necessary in the normal conduct of its business, except for any corporate right,
power,
                                      20
<PAGE>

privilege or franchise that it determines, in its reasonable, good faith
business judgment, is no longer necessary or desirable in the conduct of its
business.

               (e)  Merger and Consolidation. The Lessee shall not, during the
                    ------------------------
Term, enter into any merger with or into or consolidation with, or sell, convey,
transfer, lease or otherwise dispose of in one or a series of transactions all
or substantially all of its assets as an entirety to any Person, unless (x) no
Event of Default of the type described in Section 16(a), (f), (g) or (h) of the
Lease shall have occurred and be continuing, (y) no Event of Default shall arise
as a result of such merger, consolidation, purchase, conveyance, transfer, lease
or other disposition and (z) the surviving corporation or Person which acquires
by purchase, conveyance, transfer or lease all or substantially all of the
assets of the Lessee as an entirety (i) is a domestic corporation organized and
existing under the laws of the United States or any State of the United States,
(ii) is a Citizen of the United States, (iii) the benefits of Section 1110
available to the Owner Trustee and the Indenture Trustee immediately prior to
such transaction shall not be adversely affected as a result of such
transaction, (iv) is a Section 1110 Person, so long as such status is a
condition to the availability of protection for the Lessor and the Indenture
Trustee under Section 1110, (v) if not the Lessee, executes a duly authorized,
legal, valid, binding, and enforceable agreement, reasonably satisfactory in
form and substance to Owner Trustee, Owner Participant and Indenture Trustee,
containing an effective assumption of all of the Lessee's obligations hereunder
and under the other Operative Agreements, and each other document contemplated
hereby or thereby and delivers such instrument to the Indenture Trustee, the
Participants and the Owner Trustee, (v) provides an opinion from counsel (which
counsel may be the Lessee's General Counsel) delivered to the Owner Trustee, the
Indenture Trustee and the Owner Participant, which opinion shall be reasonably
satisfactory to the Owner Participant and the Indenture Trustee, and an
officer's certificate (which may rely, as to legal matters, on such legal
opinion), each stating that such merger, consolidation, conveyance, transfer,
lease or other disposition and the instrument noted in clause (iv) above comply
with this Section 4.02(e), that such instrument has been duly authorized,

enforceable against, such survivor or Person, and that all conditions precedent
herein provided for relating to such transaction have been complied with, and
(vi) such survivor or Person makes such filings and recordings with the FAA as

Code to evidence such merger or consolidation and such filings and recordings
necessary in order to preserve and protect the rights of the Owner Trustee, the
Indenture Trustee and the Noteholders under the Indenture.

               Upon any consolidation or merger, or any conveyance, transfer or
lease of all or substantially all of the assets of the Lessee and the
satisfaction of the conditions specified in this Section 4.02(e), the successor
corporation formed by such consolidation or into which the Lessee is merged or
the Person to which such conveyance, transfer or lease is made shall succeed to,
and be substituted for, and may exercise every right and power of, the Lessee
under this Agreement and the Lease and each other Operative Agreement and any
other document contemplated hereby and thereby to which the Lessee is a party
with the same effect as if such successor corporation had been named as the
Lessee herein and therein. No such consolidation or merger, or sale, conveyance,
transfer or lease of all or substantially all of the assets of the Lessee as an
entirety shall have the
                                      21

effect of releasing the Lessee or any successor corporation which shall
theretofore have become the Lessee hereunder in the manner prescribed in this
Section 4.02(e) from its liability hereunder or under the other Operative
Agreements. Nothing contained herein shall permit any lease, sublease, or other

name or any change in the location of the place where its records concerning the
Aircraft and the Operative Agreements are located.

          (g) Financial Statements.  The Lessee agrees to furnish to the Owner
              --------------------
Participant and the Indenture Trustee during the Term:

                                                                    --------
     that so long as the Lessee is subject to the reporting provisions of the
     Securities Exchange Act of 1934, a copy of the Lessee's quarterly report on

     the information required to be provided by this clause (i));

              (ii)  within 120 days after the end of each fiscal year of the

     year, in each case certified by independent certified public accountants of

     Exchange Act of 1934, a copy of the Lessee's annual report on Form 10-K

     files with the SEC or any governmental authority which may be substituted
     therefor or with any national securities exchange;

              (v)   promptly (but no later than five (5) Business Days) after
     the occurrence thereof and actual knowledge thereof by a Responsible
     Officer of the Lessee, notice of any Default or Event of Default and the
     action that the Lessee proposes to take with respect thereto; and

              (vi)  from time to time, such other non-confidential financial
     information as the Lessor or the Owner Participant, the Loan Participant or

                 ----------------------
a country other than the United States pursuant to Section 4.02(b), Lessee will
furnish to Owner Trustee, Indenture Trustee and each Participant annually after
such registration is effected, an opinion of special counsel reasonably
satisfactory to Owner Participant and Indenture Trustee stating that, in the
opinion of such counsel, either that (i) such action has been taken with respect

and any supplements and amendments thereof as is necessary to establish, perfect
and protect Owner Trustee's and Indenture Trustee's respective right, title and
interest in and to the Aircraft, the Indenture Estate and the Operative

covenants that on the Delivery Date there are no Lessor's Liens attributable to
it (or an Affiliate thereof).  The Owner Participant agrees with and for the
benefit of the Lessee, the Owner Trustee, the Noteholders and the Indenture
Trustee that the Owner Participant will, at its own cost and expense, take such
action as may be necessary to duly discharge and satisfy in full, promptly after
the same first becomes known to the Owner Participant, any Lessor's Lien
attributable to the Owner Participant (or an Affiliate thereof), provided,
                                                                 --------
however, that the Owner Participant shall not be required to discharge or
- -------
satisfy such Lessor's Lien which is being contested by the Owner Participant in
good faith and by appropriate proceedings so long as such proceedings do not
involve any material risk of the sale, forfeiture or loss of the Aircraft or the
Lessor's Estate or the Indenture Estate or any interest in any thereof or
otherwise materially adversely affect the validity or priority of the Lien of
the Indenture.

          (c) Assignment of Interests of Owner Participant.  At any time after
              --------------------------------------------
the Delivery Date and subject to satisfaction of the conditions set forth in
this Section 5.01(c), the Owner Participant may assign, convey or otherwise
transfer to a single Person all (but not less than all) of the Beneficial
Interest, provided that (i) the Owner Participant gives the Lessee, the Loan
          --------
Participant and the Indenture Trustee at least 10 days' notice of such
assignment, conveyance or other transfer, (ii) the Owner Participant and any
Owner Participant Guarantor shall remain liable for all obligations of the Owner
Participant under the Trust Agreement and the other Operative Agreements to
which the Owner Participant is a party to the extent (but only to the extent)
relating to the period on or before the date of such transfer, (iii) the
transferee agrees by a written instrument substantially in the form attached
hereto as Exhibit B-1 (or otherwise in form and substance reasonably
satisfactory to Lessee and Indenture Trustee) to assume liability for, and
undertake performance of, all obligations of the Owner Participant under the
Trust Agreement and the other Operative Agreements to which such Owner
Participant is a party relating to the period after the date of transfer, (iv)
at or prior to the time of such transfer, the transferee shall furnish an
opinion of counsel substantially in the form attached hereto as Exhibit B-3 (or
otherwise in form and substance reasonably satisfactory to Lessee and Indenture
Trustee) (which counsel may be in-house counsel) to the effect that such
transferee and any guarantor of the payment and performance obligations of such
transferee, as the case may be, shall have requisite power and authority and
legal right to enter into and carry out the transactions contemplated hereby;
and that such agreement and any guaranty of the transferee's obligations has
been duly authorized, executed and delivered by the transferee or the guarantor
of the payment and performance obligations of such transferee, as the case may
be, and is a valid and binding agreement of the transferee or the guarantor of
the payment and performance obligations of such transferee enforceable in
accordance with its terms, subject to customary exceptions for such opinions and
that the transfer does not violate the Applicable Law of the jurisdiction in
which such counsel is located, and (v) the Lessee shall have received with
respect to each Identified Country identified by Lessee as provided for below
either (A) a certificate from such transferee stating that it is not presently
subject to income taxation in such Identified Country or (B) an opinion from
counsel selected by Owner Participant and reasonably acceptable to Lessee that
no withholding taxes will be imposed by such Identified Country on the interest
on the Equipment Notes, assuming that Lessee is a U.S. person and assuming all
relevant facts concerning the Equipment Notes are as they

                                      26
<PAGE>

exist on the date of the transfer. Within 7 days of Lessee receiving notice of a
proposed transfer it will send to Owner Participant a list of "Identified
Countries", if any, as to which Lessee has received a written opinion from legal
counsel that there is a significant likelihood that withholding taxes will be
imposed by such Identified Country on the interest on the Equipment Notes due to
the presence of the prospective transferee in such Identified Country, together
with a copy of the opinion describing the basis on which Lessee has determined
that the country is a Identified Country; provided, however, that in no event
                                          -----------------
shall a country be considered an Identified Country if such country imposes
withholding taxes on the interest on the Equipment Notes prior to the proposed
transfer to the same extent as such country would impose such withholding taxes
after the proposed transfer. Any such transferee shall (a) be (i) a bank,
savings institution, finance company, leasing company or trust company, national
banking association acting for its own account or in a fiduciary capacity as
trustee or agent under any pension, retirement, profit sharing or similar trust
or fund, insurance company, financial institution, fraternal benefit society or
a corporation acting for its own account having a combined capital and surplus
(or, if applicable, tangible net worth or its equivalent) of not less than
$50,000,000, (ii) a subsidiary of any Person described in clause (i) where such
Person provides a guaranty of such transferee subsidiary's obligations
substantially in the form attached hereto as Exhibit B-2 (or otherwise in form
and substance reasonably satisfactory to Lessee, Owner Trustee and Indenture
Trustee), or (iii) an Affiliate of the transferring Owner Participant, so long
as such Affiliate has a combined capital and surplus (or, if applicable,
tangible net worth or its equivalent) of not less than $50,000,000 (unless the
Owner Participant remains liable for the obligations of such Affiliate under the
Operative Agreements, in which case there shall be no such net worth
requirement), (b) be legally capable of binding itself to the obligations of the
Owner Participant and shall expressly agree to assume all obligations of the
Owner Participant under the Trust Agreement and the other Operative Agreements
to which the Owner Participant is a party and (c) provide representations,
warranties, and covenants substantially similar to those contained in clauses
(a) and (c) of this Section 5.01; provided that, without the prior written
                                  --------
consent of the Lessee, such transferee shall not be an airline or other aircraft
operator or competitor of the Lessee in the business of air transportation or an
Affiliate of any thereof unless such Affiliate is (i) General Electric Company,
International Lease Finance Corporation, GPA, GATX Corporation or Bouillon
Aviation, (ii) any wholly-owned subsidiary of an entity listed in the foregoing
clause (i) that is (X) a special purpose corporation limited to holding Owner
Participant's interest in the transactions or (Y) primarily engaged in the
business of owning and leasing assets to third-party lessees and which is not
engaged in the business of an airline, other commercial aircraft operation or
freight forwarder or (iii) an entity from which Lessee has leased an aircraft
directly (or through a trust) and not as a result of the transfer to such entity
of any aircraft subject to an existing lease with Lessee; provided that Lessee's
                                                          --------
consent shall not be required if an Event of Default shall have occurred and be
continuing at the time of such transfer; and provided further that neither such
                                             -------- -------
transferee nor any Affiliate thereof shall (x) be a party to any material
litigation or arbitration (whether as plaintiff or defendant) with the Lessee or
any Affiliate of the Lessee or (y) be attempting a hostile takeover of the
Lessee or any Affiliate of the Lessee.  A transferee hereunder shall be (I) a
"United States person" within the meaning of Section 7701(a)(30) of the Code and
(II) a Citizen of the United States or has established a voting trust, voting
powers or other arrangement reasonably satisfactory to the Indenture Trustee,
the Owner Trustee, and the Lessee to permit the Owner Trustee to be the

                                      27
<PAGE>

registered owner of the Aircraft under the Transportation Code, without in any
way restricting the Lessee's use and operation of the Aircraft.  The Owner
Trustee shall not be on notice of or otherwise bound by any such assignment,
conveyance or transfer unless and until it shall have received an executed
counterpart of the instrument of such assignment, conveyance or transfer.  Upon
any such disposition by the Owner Participant to a transferee as above provided,
the transferee shall be deemed the "Owner Participant" for all purposes of the
Operative Agreements, and shall be deemed to have acquired the same interest in
the Lessor's Estate as theretofore held by its transferor; and each reference
therein to the "Owner Participant" shall thereafter be deemed a reference to
such transferee and the transferring Owner Participant shall be released from
all of its obligations under the Operative Agreements to the extent such
obligations are assumed by such transferee.  All reasonable fees and expenses
incurred by Lessee, Owner Participant, Indenture Trustee, any Noteholder or
Owner Trustee in connection with any transfer by the Owner Participant permitted
by this Section 5.01(c) will be promptly reimbursed by the Owner Participant,
unless an Event of Default has occurred and is continuing, in which case any
fees and expenses incurred by Lessee shall not be so reimbursed; provided,
                                                                 --------
however, that in each case bills shall be submitted to the Owner Participant
- -------
prior to payment.  Each of the parties hereto agree, to the extent so requested
by the Owner Participant,

to use reasonable efforts to cooperate with the Owner Participant in effecting
any assignment, conveyance or other transfer permitted pursuant to this Section
5.01(c), including providing its written consent and acknowledgement to any such
assignment, conveyance or other transfer and, in the case of the Lessee,
providing new insurance certificates that reflect the interest of the
transferee.  After the expiration or termination of the Term of the Lease and
after the Lien of the Indenture shall have been discharged in accordance with
its terms, the Owner Participant may freely assign, convey or otherwise transfer
all or any part of the Beneficial Interest without compliance with this Section
5.01(c), provided that no such transfer shall release the Owner Participant from
its obligations under the Operative Agreements accrued prior to the end of the
Term.

          (d) Actions with Respect to Lessor's Estate, Etc.  The Owner
              ---------------------------------------------
Participant agrees that it will not take any action to subject the Lessor's
Estate or the trust established by the Trust Agreement, as debtor, to the
reorganization or liquidation provisions of the Bankruptcy Code or any other
applicable bankruptcy or insolvency statute.

          (e) Citizenship.  The Owner Participant agrees, solely for the benefit
              -----------
of the Lessee, each Noteholder, the Indenture Trustee and the Owner Trustee,
that if at any time on or after the Delivery Date when the Aircraft is
registered or the Lessee proposes to register the Aircraft in the United States
(i) either the Owner Participant shall cease to be, or an event which has been
publicly disclosed has occurred of which the Owner Participant has knowledge and
which will cause the Owner Participant to cease to be, a Citizen of the United
States, and (ii) the Aircraft shall or would therefore become ineligible for
registration in the name of the Owner Trustee under the Transportation Code and
regulations then applicable thereunder (such eligibility to be determined
without regard to any provision of law that permits the U.S. registration of the
Aircraft by restricting where it is based or used), then the Owner Participant
shall give notice thereof to the Lessee, the Owner Trustee, each Noteholder and
the Indenture Trustee and shall (at its own expense and without

                                      28
<PAGE>

any reimbursement or indemnification from the Lessee) immediately (and in any
event within a period of 20 days) promptly (x) effect a voting trust or other
similar arrangement, (y) transfer in accordance with the terms of this Agreement
and the Trust Agreement all its rights, title and interest in and to such Trust
Agreement, the Lessor's Estate, this Agreement and the other Operative
Agreements to which it is a party, or (z) take any other alternative action that
would prevent any deregistration, or maintain or permit the United States
registration, of the Aircraft (determined without regard to any provision of law
that permits the U.S. registration of the Aircraft by restricting where it is
based or used).  Each party hereto agrees, upon the request and at the sole
expense of the Owner Participant, to cooperate with the Owner Participant in
complying with its obligations under the provisions of the first sentence of
this Section 5.01(e), but without any obligation on the part of such other party
to take any action believed by it in good faith to be unreasonably burdensome to
such party or materially adverse to its business interests.

          (f) Tail Insurance.  If (i) any purchaser of the Aircraft from the
              --------------
Owner Trustee or the Owner Participant agrees to include the Owner Trustee and
the Owner Participant as a named additional insured on any liability insurance
policy relating to the Aircraft for the period referred to below, (ii) such
purchase occurs within two years following repayment in full of the Equipment
Notes, (iii) the initial Loan Participant is the Noteholder at the time of such
repayment, (iv) such purchaser is not the Lessee or the Manufacturer or any
Affiliate or designee thereof, and (v) such purchase does not occur in
connection with the exercise of remedies under the Lease or the Indenture or the
termination of the Lease pursuant to Section 14 thereof, the Owner Participant
shall use reasonable efforts to obtain an agreement from such purchaser to
include (to the same extent as is provided to the Owner Participant or the Owner
Trustee) the Indenture Trustee and the Noteholders as named additional insureds
on any liability policy for two years following the repayment in full of the
Equipment Notes or until the next major overhaul ("D-check" or equivalent),
whichever is earlier.

          Section 5.02. Citizenship.
                        -----------

          (a) Generally.  The Owner Trustee, in its individual capacity,
              ---------
represents and warrants that it is and on the Delivery Date will be a Citizen of
the United States.  If the Owner Trustee in its individual capacity does not
comply with the requirements of this Section 5.02, the Owner Trustee and the
Indenture Trustee hereby agree that no Default shall be deemed to exist due to
non-compliance by the Lessee with the registration requirements in the Lease or
in Section 4.02(b) hereof occasioned solely by such noncompliance of the Owner
Trustee.

          (b) Owner Trustee.  The Owner Trustee, in its individual capacity,
              -------------
covenants that if at any time on or after the Delivery Date any of its
Responsible Officers shall have actual knowledge that it has ceased to be a
Citizen of the United States, it will resign immediately as the Owner Trustee if
such citizenship is necessary for registration of the Aircraft in the Owner
Trustee's name under the Transportation Code as in effect at such time (such
necessity to be determined without regard to any provision of law that permits
the U.S. registration of the Aircraft by restricting where it is based or used)
or, if it is not necessary for such registration, if the Owner Trustee is

                                      29
<PAGE>

informed in writing by the Lessee, the Indenture Trustee or any Participant that
such lack of United States citizenship would have any adverse effect on the
Lessee, the Indenture Trustee or any Participant. The Owner Trustee, in its
individual capacity, further covenants that if at any time it appears reasonably
probable that it will cease to be a Citizen of the United States based on
information that is (i) known to a Responsible Officer of the Owner Trustee or
(ii) generally known to the public, it will promptly so notify, to the extent
permitted by law, all parties to this Agreement.

limiting its other representations and warranties provided for in this Article

     part, and do not contravene its articles of association or by-laws; each of
     this Agreement and the other Operative Agreements to which it is or is to
     be a party has been duly authorized, and has been duly executed and

     terms and provisions thereof will violate any federal or Delaware law or
     regulation governing Trust Company's banking or trust powers,

              (iii) (A)  assuming due authorization, execution and delivery by
     each other party thereto, each of the Operative Agreements to which it is
     or is to be party when duly executed and delivered will, to the extent each
     such document is entered into by Trust Company in its individual capacity,
     constitute the legal, valid and binding obligation of Trust Company in its
     individual capacity enforceable against it in such capacity in accordance
     with its respective terms, except as such enforceability may be limited by
     bankruptcy, insolvency, reorganization or other similar laws or equitable

                                      30
<PAGE>

     considered in a proceeding in equity or at law), and the performance by
     Trust Company in its individual capacity of any of its obligations

     other party thereto, each of the Operative Agreements to which it is or is
     to be party when duly executed and delivered will, to the extent each such

     or proceedings against Trust Company, either in its individual capacity or
     as the Owner Trustee, before any court or administrative agency which would
     materially adversely affect the ability of Trust Company, either in its

     of any change in its chief executive office or of any change in its name or
     any change in the location of the place where its records concerning the
     Aircraft and the Operative Agreements are located;

          (vi)   neither the execution and delivery by it, either in its
     individual capacity or as the Owner Trustee, as the case may be, of any of
     the Operative Agreements to which it is or is to be a party, requires on
     the part of Trust Company in its individual capacity or any of its
     Affiliates the consent or approval of or the giving of notice to, the

     federal or Delaware governmental authority or agency governing its banking

     of the State of Delaware in connection with the execution, delivery or
     performance of any Operative Agreement by Owner Trustee or in connection

     validly existing in good standing under the laws of the State of Maryland
     and has the corporate power and authority to enter into and perform its
     obligations under the Indenture, this Agreement and the other Operative

     Maryland law or regulation relating to its banking or trust powers or
     contravene or result in any breach of, or constitute any default under, its
     articles of incorporation or by-laws;

              (iii) assuming due authorization, execution and delivery by each
     other party thereto, each of the Indenture and this Agreement, and the

     with its terms except as such enforceability may be limited by bankruptcy,
     insolvency, reorganization or other similar laws or equitable principles of

                ------------------------------
and warrants that, as of the Delivery Date (unless any such representation and
warranty is specifically made as of an earlier date, in which case the Loan
Participant represents and warrants as of such earlier date):

              (ii)  the Loan Participant acknowledges that its Equipment Note
     has not been registered under the Securities Act of 1933, as amended, and
     the Indenture has not been registered under the Trust Indenture Act of

                    ---------------------------
transfer its interest in and to the Equipment Note held thereby to any Person
which is not an airline or an Affiliate of an airline; provided, however, (i)
                                                       --------  -------
the Loan Participant shall not transfer any interest in an Equipment Note except
pursuant to a transaction which is exempt from registration under the Securities
Act of 1933, as amended and (ii) in connection with any such transfer, (A) the
proposed transferee shall make a representation for the benefit of the Lessee
identical to the representation made by the Loan Participant in Section

transferee to purchase such interest in such Equipment Note, and (B) the
proposed transferee shall agree to be bound by the provisions of the Indenture
(to the extent applicable to the Loan Participant) and this Agreement
(including, without limitation, this Section 5.08(b)) in connection with any

          (a)     Subject to compliance by the Lessee with all of its
obligations under the Operative Agreements, each of the Owner Participant, the
Owner Trustee, the Indenture Trustee, the Noteholders and the Lessee covenants
and agrees that if the Lessee elects to purchase the Aircraft on the EBO Date
pursuant to Section 13(b) of the Lease, if no Default or Event of Default shall
exist, then, upon compliance with the applicable provisions of the Operative
Agreements, the Owner Trustee will transfer to the Lessee, without recourse or
warranty (except as to the absence of Lessor's Liens attributable to the Owner
Trustee) but subject to the Lien of the Indenture, all of the Owner Trustee's
right, title and interest in and to the Aircraft, and if the Lessee, in
connection with such purchase, elects to assume the obligations of the Owner
Trustee to the Indenture Trustee and the Noteholders under the Indenture, the
Equipment Notes, and hereunder, the Lessee shall so notify the Indenture Trustee
(such notice to be given at least 30 and not more than 60 days prior to the
effective date of such assumption), and each of the parties shall execute and
deliver documentation satisfactory in form and substance to the Indenture
Trustee and each Noteholder permitting the Lessee to assume such obligations on
the basis of full recourse to the Lessee, maintaining for the benefit of the
Noteholders the security interest in the Aircraft created by the Indenture, and
upon compliance with the provisions of this Section 5.10, such documentation
shall become effective releasing the Owner Participant and the Owner Trustee
from all obligations in respect of the Equipment Notes, the Indenture, this
Agreement, and the other Operative Agreements, except any obligations relating
to the period prior to such assumption and take all such other actions, at the
Lessee's expense, as are reasonably necessary to permit such assumption by the
Lessee.

          (b)     In connection with such assumption:

             (i)  the Lessee shall execute and deliver an instrument
     satisfactory in form and substance to the Indenture Trustee and each
     Noteholder (A) pursuant to which the Lessee irrevocably and unconditionally
     assumes and undertakes, with full recourse to the Lessee, to pay, satisfy,
     and discharge when and as due (at the stated maturity thereof, by
     acceleration or otherwise) the principal of, Make-Whole Amount, if any,
     interest, and all other sums owing on all Outstanding Equipment Notes (or
     on the Lessee's substituted obligations) in accordance with their terms,
     and punctually to perform and observe all of the covenants and obligations
     hereunder and under the Indenture and the Equipment Notes (as the same may
     be amended in connection with such assumption) to be performed or observed
     by the Owner Trustee, and (B) which contains amendments to the Indenture,
     in form and substance as satisfactory to the Indenture Trustee and each
     Noteholder, which amend the Indenture so that it is substantially in the
     form of the Trust Indenture and Security Agreement [N570ML]

     5.10(b), any Uniform Commercial Code financing statements relating thereto,
     and any other documents which shall be necessary (or reasonably requested
     by the Indenture Trustee or any Noteholder) to establish the Lessee's title
     to and interest in the Aircraft or to reflect the substitution of the
     Lessee for the Owner Trustee under the Operative Agreements or to continue
     the perfection of the security interests in the Aircraft and the other
     rights, property, and interests included in the Indenture Estate for the
     benefit of the Noteholders shall be filed in such form, manner, and places
     as are necessary or, in the reasonable opinion of the Indenture Trustee or
     any Noteholder, advisable for such purpose;

              (iii)  each Noteholder and the Indenture Trustee shall have
     received an insurance report dated the effective date of such assumption of
     an independent insurance broker and certificates of insurance, each in form
     and substance satisfactory to each Noteholder and the Indenture Trustee, as
     to the due compliance as of the effective date of such assumption with the
     terms of Section 9 of the Lease relating to the insurance with respect to
     the Aircraft (provided that the required amount of all-risk hull insurance,
                   --------

              (vi)   each Noteholder and the Indenture Trustee shall have
     received (x) an opinion of independent tax counsel chosen by Lessee and
     reasonably acceptable to the Noteholders and the Indenture Trustee to the
     effect that such assumption by the Lessee will not result in any adverse
     tax consequences to such Noteholder or the Indenture Trustee or (y) an
     indemnity from the Lessee for any adverse tax consequences to such
     Noteholder and the Indenture Trustee resulting from such assumption that is
     reasonably acceptable to such Noteholder and the Indenture Trustee;

              (vii)  each Noteholder and the Indenture Trustee shall have
     received (A) from counsel for the Lessee a legal opinion, in form and

     and (z) with respect to the continued availability of the benefits of
     Section 1110 to the Indenture Trustee for the benefit of the Noteholders
     with respect to the Aircraft after giving effect to such assumption (but

     Noteholders prior to such assumption assuming compliance with the Operative
     Agreements by the parties thereto), (B) from counsel to the Indenture
     Trustee, counsel to Lessee and Lessee's special aviation counsel, a legal
     opinion comparable to the respective opinions delivered on the Delivery

     in light of such assumption, and (C) in the case of each opinion described
     in clause (A) or (B) above, covering such additional matters as the
     Indenture Trustee or the Noteholders shall reasonably request.

          (c)   whether or not the assumption contemplated by this Section 5.10
is accomplished, the Lessee shall pay all reasonable expenses (including
reasonable fees and expenses of counsel) of the Indenture Trustee, the Owner
Trustee, each Noteholder and the Owner Participant in connection with such
assumption.

          Section 5.11. Compliance with Trust Agreement, Etc.  Each of the Owner
                        -------------------------------------
Participant, Trust Company, and the Owner Trustee agrees with the Lessee, the
Indenture Trustee and the Noteholders that so long as the Lien of the Indenture
shall be in effect it will (i) comply with all of the terms of the Trust
Agreement applicable to it in its respective capacity, the noncompliance with
which would adversely affect any such party and (ii) not take any action, or
cause any action to be taken, to amend, modify or supplement any other provision
of the Trust Agreement in a manner that would adversely affect any such party
without the prior written consent of such party.  The Owner Trustee confirms for
the benefit of the Lessee, the Indenture Trustee and the Noteholders that it
will comply with the provisions of Article 2 of the Trust Agreement.
Notwithstanding anything else to the contrary in the Trust Agreement, so long as
the Lease remains in effect, the Owner Participant agrees not to terminate or
revoke the trust created by the Trust Agreement without the consent of the
Lessee.  If and so long as the Indenture shall not have been discharged in
accordance with its terms the consent of the Indenture Trustee shall also be
required prior to any termination or revocation of such trust.  In addition, the
Owner Trustee will, at the Lessee's expense, promptly and duly execute and
deliver to the Indenture Trustee such documents and assurances including,
without limitation, conveyances, financing statements and continuation
statements with respect to financing statements and take such further action as
the Indenture Trustee may from time to time reasonably request in order to
protect the rights and remedies created or intended to be created in favor of
the Indenture Trustee under the Indenture and to create for the benefit of the
Noteholders a valid first priority Lien with respect to, and a first and prior
perfected security interest in, the Indenture Estate.

will not during the Term enter into any amendment or supplement to the Indenture

have the effect of limiting any right or of increasing any obligation or
liability of the Lessee under the terms of the Lease or any other Operative
Agreement.

     have been properly included in the Purchase Price;

              (ix)   Any Taxes imposed on the Owner Trustee or Owner Participant
     which would not have been imposed but for a Lessor's Lien or any Taxes

     to, resulting from, arising out of or in connection with a "prohibited

     by reason of (x) any voluntary transfer by such Tax Indemnitee of all or

     Operative Agreement, the Equipment Notes, or shares of stock in such Tax
     Indemnitee with respect to such Tax Indemnitee (other than transfers which
     occur during or as a result of the continuance of any Event of Default) or
     (y) an involuntary transfer of the Equipment Notes, rights under the
     Operative Agreements or shares of stock in a Tax Indemnitee resulting from
     any bankruptcy, foreclosure or similar proceedings in which a Tax
     Indemnitee is the debtor (other than transfers which occur during or as a
     result of the continuance of an Event of Default);

              (xvii)  In the case of a Noteholder, Taxes imposed by Section
     4975 of the Code or any successor provision thereto; and

             (xviii)  In the case of a Noteholder, any Excluded Noteholder
     Withholding Tax, as defined in Section 6.01(c) below.

             (c)      Withholding.  The Indenture Trustee shall withhold any
                      -----------
Taxes required to be withheld on any payment to a Noteholder pursuant to Section
3.08 of the Indenture. If the Lessee or the Indenture Trustee is required by law
or regulation to make any deduction or withholding of any Taxes from any payment
to a Noteholder under the Operative Agreements, then the amount payable by the
Lessee will be increased by such additional amounts (together with interest,
penalties and additions to Tax), as may be necessary to ensure that, after such
deduction or withholding, the Noteholder receives on an After Tax Basis the full
amount it would have received had the payment not been subject to deduction or
withholding of Taxes other than any Taxes which are Excluded Noteholder
Withholding Taxes (as defined below). If the Indenture Trustee fails to withhold
and pay over a Tax required to be withheld and paid over with respect to any
Noteholder or any claim is otherwise asserted by a taxing authority against the
Owner Trustee or Owner Participant in connection with any withholding tax, the
Lessee will indemnify the Owner Trustee and the Owner Participant (without
regard to the exclusions set forth in Section 6.01(b) hereof) on an After Tax
Basis against any such Taxes and any interest and penalties with respect
thereto, along with any other costs (including reasonable attorney's fees)
incurred in connection with any such claim.

     An Excluded Noteholder Withholding Taxes is any Tax which is a U.S. federal
withholding tax on payments of interest or Rent by the Lessee or the Indenture
Trustee to a Noteholder, if such Noteholder satisfies none of the following
conditions:

         (x) such Noteholder is a corporation organized under the laws of a
     jurisdiction in the United States, any State thereof or the District of
     Columbia;

         (y) such Noteholder has delivered to the Lessee and the Indenture
     Trustee, when such Noteholder first becomes a Noteholder, two copies of
     either United States Internal Revenue Service Form 1001 or Form 4224 or any
     subsequent versions thereof or successors thereto, properly completed and
     duly executed by such Noteholder claiming complete exemption from U.S.
     federal withholding tax on payments of interest by the Lessee and the
     Indenture Trustee under the Operative Agreements and has, thereafter at
     each time it has been so

                                      43
<PAGE>

     requested by the Lessee or the Indenture Trustee; delivered within a
     reasonable time an updated Form 1001 or Form 4224 or subsequent version
     thereof or successor thereto (each an "Updated Form") unless the failure to
     deliver an Updated Form shall be because such Noteholder cannot truthfully
     complete such form solely as a result of a change in law, regulation, or
     other official pronouncement;

         (z)  such Noteholder is not a "bank" as such term is defined for
     purposes of Section 881(c)(3)(A) of the Code or any successor provision as
     in effect on the date such Noteholder acquired its Notes, such Noteholder
     has delivered to the Lessee and the Indenture Trustee, upon first becoming
     a Noteholder, two copies of United States Internal Revenue Service Form W-8
     or any subsequent versions thereof or successors thereto, properly
     completed and duly executed by such Noteholder claiming complete exemption
     from U.S. federal withholding tax on payments of interest by the Lessee and
     the Indenture Trustee under this Agreement and the other Note Purchase
     Documents together with a certificate in the form attached as Exhibit C
     (the "Nonbank Certificate") and has, thereafter, at each time it has been
     so requested by the Lessee or the Indenture Trustee, delivered within a
     reasonable time an updated Form W-8 and Nonbank Certificate or subsequent
     version (each an "Updated Form") unless such person cannot truthfully
     provide such Updated Form solely as a result of a change in law,
     regulation, or other official pronouncement;

If the Lessee or the Indenture Trustee makes any payment hereunder in respect of
which it is required by Applicable Law to make any deduction or withholding or
if the Lessee or the Indenture Trustee is otherwise required to pay any Taxes,
the Lessee shall pay the full amount due or to be deducted or withheld to the
relevant taxation authority or other Governmental Authority within the time
allowed for such payment under Applicable Law, in each case, and shall deliver
to the relevant Noteholder Tax Indemnitee as soon as practicable after it has
made such payment to the applicable Governmental Authority a receipt issued by
such Governmental Authority or a statement of the Company confirming the payment
to such Governmental Authority of all amounts so required to be deducted or
withheld from such payment.

          Section 6.02.  After Tax Basis.  The amount which the Lessee shall be
                         ---------------
required to pay with respect to any Tax indemnified against under Section 6.01
(an "Indemnifiable Tax") shall be an amount sufficient to restore the Tax
Indemnitee, on an After Tax Basis, to the same position such party would have
been in had such Tax not been incurred, taking into account any tax benefits
recognized by such Tax Indemnitee as a result of the Indemnifiable Tax.  If any
Tax Indemnitee actually realizes a tax benefit (whether by credit, deduction or
otherwise), or would have realized such a benefit as to which it has been given
notice if properly claimed (but only if the Lessee has (I) notified such Tax
Indemnitee of such benefit, (II) provided to such Tax Indemnitee an opinion of
counsel selected by Lessee and reasonably acceptable to such Tax Indemnitee that
there is reasonable basis for making such claim, and (III) the Tax Indemnitee
does not determine in good faith that it will suffer an unindemnified adverse
consequence of making such claim), and with respect to Owner Participant, the
Owner Participant has not determined in good faith that claiming such benefit
would have a material adverse impact on the Owner Participant or an Affiliate
thereof, by reason of the

                                      44
<PAGE>

payment of any Tax paid or indemnified against by the Lessee, provided that an
Event of Default has not occurred and is not continuing, such Tax Indemnitee
shall promptly pay to the Lessee, to the extent such tax benefit was not
previously taken into account in computing such payment or indemnity, but not
before the Lessee shall have made all payments then due to such Tax Indemnitee
under this Agreement, the Tax Indemnity Agreement and any other Operative
Agreement, an amount equal to the lesser of (x) the sum of such tax benefit plus
any other tax benefit realized by such Tax Indemnitee that would not have been
realized but for any payment made by such Tax Indemnitee pursuant to this
sentence and not already paid to the Lessee, or (y) the amount of the payment
made under Section 6.01 hereof and this Section 6.02 by the Lessee to such Tax
Indemnitee plus the amount of any other payments by the Lessee to such Tax
Indemnitee theretofore required to be made under this Section 6.02 and Sections
6.01 and 6.05 hereof (and the excess, if any, of the tax benefit over the
applicable amount described in clause (x) over the amount described in clause
(y) above shall be carried forward and applied to reduce pro tanto any
                                                         --- -----
subsequent obligations of the Lessee to make payments to such Tax Indemnitee
pursuant to Section 6.01 hereof). If an amount payable by any Tax Indemnitee to
the Lessee pursuant to this Section 6.02 is not paid when due because of the
occurrence and continuation of any Event of Default, such amount shall be
payable by any Tax Indemnitee to the Lessee upon the Lessee's curing all Events
of Default. The Lessee shall reimburse on an After Tax Basis such Tax Indemnitee
(subject to Section 6.01(b), but only insofar as subsections (iv), (vi), (x),
(xi) and (xiii) thereof would apply) for any payment of a tax benefit pursuant
to the preceding sentence (or a tax benefit otherwise taken into account in
calculating the Lessee's indemnity obligation hereunder) to the extent that such
tax benefit is subsequently disallowed or reduced.

         In determining the order in which any Tax Indemnitee utilizes
withholding or other foreign taxes as a credit against such Tax Indemnitee's
United States income taxes, such Tax Indemnitee shall be deemed to utilize (i)
first, all foreign taxes other than those described in clause (ii) below; and
(ii) then, on a pro rata basis, all foreign taxes with respect to which such Tax
Indemnitee is entitled to obtain indemnification pursuant to an indemnification
provision contained in any lease, loan agreement, or other financing document
(including this Participation Agreement) that is similar to the indemnification
provision in this Article 6.

          Section 6.03. Time of Payment. Any amount payable to a Tax Indemnitee
                        ---------------
pursuant to this Article 6 shall be paid promptly, but in any event within 30
days after receipt of a written demand therefor from such Tax 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 in
                                                             --------
the case of amounts which are being contested by the Lessee in good faith or by
the Tax Indemnitee in either case pursuant to Section 6.04 hereof, or subject to
verification proceedings pursuant to Section 6.11 hereof, such amount shall be
payable within 30 days after the time such contest or verification proceeding,
as the case may be, is finally resolved. In no event shall any amount be payable
under Section 6.01 until two Business Day prior to the due date for Tax in
issue.

<PAGE>

          (a) Notice of Claim.  If a written claim is made against any Tax
              ---------------
Indemnitee for Taxes with respect to which the Lessee is liable for a payment or
indemnity hereunder, such Tax Indemnitee shall promptly (but in any event within
30 days of receipt thereof) give the Lessee notice in writing of such claim and
shall furnish the Lessee with copies of any written requests for information
sent to such Tax Indemnitee from any taxing authority to the extent relating to
such Taxes with respect to which the Lessee may be required to indemnify
hereunder; provided, however, that the failure of a Tax Indemnitee to give such
           --------  -------
notice or furnish such copy shall not terminate any of the rights of such Tax
Indemnitee under this Article 6, except (A) to the extent that the Lessee's
contest rights have been materially and adversely impaired by the failure to
provide such notice or copy or (B) except with respect to a Noteholder Tax
Indemnitee, to the extent that such failure results in the imposition of, or an
increase in the amount of, any penalties, interest or additions to Tax related
to the Tax which is the subject of such claim or proceeding.

          (b) Request for Contest.  If a written claim shall be made for any
              -------------------
Tax, other than an Income Tax, for which the Lessee may be obligated to
indemnify pursuant to Section 6.01 hereunder, and under applicable law of the
taxing jurisdiction the Lessee is allowed to contest directly such Tax and the
Tax to be contested is not reflected in a report or return with other Taxes of
any Tax Indemnitee (as confirmed in writing by such Tax Indemnitee) and if the
Tax Indemnitee determines in good faith that it will not suffer any adverse
consequences as a result (as confirmed in writing by such Tax Indemnitee), then
the Lessee shall be permitted, at its expense and in its own name, or, if
consented to in writing by the Tax Indemnitee, in the name of such Tax
Indemnitee, to contest the imposition of such Tax; provided, however, that the
                                                   --------  -------
Lessee shall not be permitted or entitled to contest any Tax unless (A) such
contest will not result in the risk of an imposition of criminal penalties or a
more than de minimis risk of a sale, forfeiture or loss of the Aircraft, the
Airframe, the Engines or any part thereof or the creation of any Lien other than
Liens for Taxes of the Lessee (x) either not yet due or being contested in good
faith by appropriate proceedings so long as such proceedings do not involve the
risk of an imposition of criminal penalties or the more than de minimis risk of
any sale, forfeiture or loss of the Aircraft, and (y) for the payment of which
such reserves, if any, as required to be provided under generally accepted
accounting principles have been provided and, to the extent permitted by law,
the Lessee shall be entitled to withhold payment during pendency of such
contest, (B) if an Event of Default shall have occurred and be continuing, the
Lessee shall have provided security for its obligations hereunder reasonably
satisfactory to the Owner Participant by placing in escrow funds to cover any
such obligations, (C) the Lessee shall have agreed to pay such Tax Indemnitee on
demand and on an After Tax Basis all costs and expenses that such Tax Indemnitee
actually incurs in connection with contesting such claim (including, without
limitation, all costs, expenses, losses, reasonable legal and accounting fees,
disbursements, or penalties, interest and addition to tax), (D) if such contest
shall be conducted in a manner requiring the payment of the claim in advance,
the Lessee shall have advanced sufficient funds, on an interest free basis, to
make the payment required, and agreed to indemnify the Tax Indemnitee against
any additional net adverse tax consequences on an After Tax Basis to such Tax
Indemnitee of such advance, (E) if such contest shall be conducted in a manner
requiring the payment of the claim, the Lessee shall have paid the amount
required, (F) Lessee shall have acknowledged its liability for such claims, (G)
such contest and related contests involving other equipment involve

                                      46
<PAGE>

potential payments and/or indemnities by the Lessee (whether or not such
indemnity is pursuant to this Agreement) of at least $25,000 in the aggregate,
and (H) independent tax counsel selected by Owner Participant and reasonably
acceptable to the Lessee has rendered an opinion within 30 days of the Owner
Participant providing notice of the claim to the Lessee that a Reasonable Basis
exists for contesting such claim.

          If the Lessee shall so request within 30 days after receipt of such
notice from a Tax Indemnitee under this Section 6.04 hereof and with respect to
a Tax for which the Lessee may be obligated to indemnify pursuant to Section
6.01, such Tax Indemnitee shall in good faith at the Lessee's after-tax expense
contest the imposition of such Tax; provided, however, that such Tax Indemnitee,
                                    --------  -------
after considering in good faith any advice of the Lessee and the Lessee's
counsel concerning the forum in which the adjustment is most likely to be
favorably resolved, may in its sole discretion select the manner and forum for
such contest and determine whether any such contest shall be made by (a)
resisting payment thereof if lawful and practicable or not paying the same
except under protest if protest is necessary and proper in each case so long as
non-payment will not result in a more than de minimis risk of the sale,
forfeiture or loss of, or the creation of a Lien other than a Permitted Lien on
the Aircraft, Airframe or any Engine or any risk of criminal liability; or (b)
if the payment be made, using reasonable efforts to obtain a refund thereof in
appropriate administrative and/or judicial proceedings;  provided further,
                                                         -------- -------
however, that at such Tax Indemnitee's option, such contest shall be conducted
- -------
by the Lessee in the name of such Tax Indemnitee if such Tax Indemnitee so
requests in writing and that in no event shall such Tax Indemnitee be required
or the Lessee permitted to contest under this paragraph the imposition of any
Tax for which the Lessee may be obligated pursuant to this Section 6.01 unless:

          (i)    in the case of an Income Tax, the Lessee shall have furnished
     at the Lessee's expense an opinion of counsel selected by the Lessee and
     reasonably satisfactory to such Tax Indemnitee to the effect that a
     Reasonable Basis exists for pursuing such contest;

          (ii)   the Lessee shall have agreed to pay such Tax Indemnitee on
     demand and on an After Tax Basis all reasonable costs and expenses that
     such Tax Indemnitee may incur in connection with contesting such claim
     (including, without limitation, all costs expenses, losses, reasonable
     legal and accounting fees, disbursements, penalties, interest and additions
     to tax);

          (iii)  such Tax Indemnitee shall have determined that the action to be
     taken will not result in any more than de minimis danger of sale,
     forfeiture or loss of, or the creation of any Lien other the Liens for
     Taxes of the Lessee (or any Sublessee) either not yet due or being
     contested in good faith by appropriate proceedings so long as such
     proceedings do not involve any more than de minimis risk of the sale,
     forfeiture or loss of the Aircraft, the Airframe or any Engine or any
     interest therein and for the payment of which such reserves, if any, as are
     required to be provided under generally accepted accounting principles have
     been provided;

                                      47
<PAGE>

          (iv)   if an Event of Default shall have occurred and be continuing,
     the Lessee shall have provided security for its obligations hereunder
     reasonably satisfactory to the Owner Participant by placing in escrow
     sufficient funds to cover any such obligations;

          (v)    Lessee shall have acknowledged its liability in writing for
     such claims;

          (vi)   such contest and related contests involving other equipment
     involve potential payments and/or indemnities by the Lessee (whether or not
     such indemnity is pursuant to this Agreement) of at least $25,000 in the
     aggregate; and

          (vii)  if such contest shall be conducted in a manner requiring the
     payment of the claim in advance, the Lessee shall have advanced sufficient
     funds, on an interest free basis, to make the payment required, and agreed
     to indemnify the Tax Indemnitee against any additional net adverse tax
     consequences on an After Tax Basis to such Tax Indemnitee of such advance.

          If requested by the Lessee, the Tax Indemnitee shall appeal any
adverse administrative or judicial decision, except that the Tax Indemnitee
shall not be required to pursue any appeals to the United States Supreme Court
provided that with respect to an appeal of a judicial decision it must be more
likely than not that such appeal will be successful. Notwithstanding the
foregoing, the Lessee shall not be permitted or entitled to contest any such Tax
in its own name unless the Tax is reflected in a report or a return of the
Lessee or raised in an audit or other proceeding of the Lessee, the Lessee is
allowed to contest such Tax under applicable law of the taxing jurisdiction, and
no tax return of the Tax Indemnitee is kept open as a result of such contest
beyond the applicable statute of limitations period. If the Lessee is permitted
under applicable law to contest a Tax asserted against the Lessee and the same
or similar Tax is also asserted against the Tax Indemnitee, subject to the
conditions herein, each of the Lessee and such Tax Indemnitee shall conduct its
contest in its own name and the Lessee and such Tax Indemnitee will cooperate in
a reasonable manner with respect to the respective contests of such Tax.

          If such Tax Indemnitee shall elect to contest a claim for Taxes by
paying the Tax claimed (including such amounts payable as interest, penalties or
additions to tax) and seeking a refund, then upon timely request by such Tax
Indemnitee, the Lessee shall advance to such Tax Indemnitee on an interest-free
basis the amount of such Tax (including such amounts payable as interest,
penalties or additions to tax) and shall indemnify the Tax Indemnitee on an
After Tax Basis against any additional net cost to such Tax Indemnitee with
respect to such advance.

          (c)    Declining to Contest; Settlement.  (i)  If, after the Lessee
                 --------------------------------
has properly requested a contest in accordance with this Section 6.04 and Lessee
is then complying with the terms of this Section 6.04, any Tax Indemnitee shall
at any time decline to take any action required under Section 6.04 with respect
to such contest, then, if such failure shall cause the contest to be determined
adversely or shall preclude such contest as a matter of law, the Lessee shall
not be obligated to indemnify such Tax Indemnitee for such Tax and such Tax
Indemnitee shall reimburse

                                      48
<PAGE>

the Lessee for all amounts previously advanced by the Lessee in connection with
such contest (other than costs and expenses of such contest).

          (ii)  No Tax Indemnitee shall settle a contest of any indemnified Tax
     without requesting the Lessee's written consent (which consent will not be
     unreasonably withheld, as determined in the Lessee's good faith judgment).
     If any Tax Indemnitee shall settle a contest for any Tax without receiving
     the Lessee's written consent, then the Lessee shall not be obligated to
     indemnify such Tax Indemnitee for such Tax and the Tax Indemnitee shall
     reimburse the Lessee for all amounts previously advanced with respect to
     such contest (other than costs and expenses of such contest).
     Notwithstanding the preceding two sentences, no Tax Indemnitee shall be
     required to take or continue any action unless the Lessee shall have agreed
     to pay the Tax Indemnitee on a current and After Tax Basis all reasonable
     costs and expenses (including, without limitation, all costs, expenses,
     losses, reasonable attorney's and accountant's fees, disbursements,
     penalties, interest and additions to tax) which such Tax Indemnitee may
     incur as a result of contesting such Taxes.

          (d) Continuing Claims.  Notwithstanding anything contained in this
              -----------------
Section 6.04 to the contrary, no Tax Indemnitee shall be required to contest any
claim if the subject matter thereof shall be of a continuing nature and shall
have previously been adversely decided pursuant to the contest provisions of
this Section 6.04 unless there shall have been a change in the law (including,
without limitation, amendments to statutes or regulations, administrative
rulings and court decisions) or the Lessee shall have provided new facts after
such claim shall have been so previously decided, and such Tax Indemnitee shall
have received an opinion of independent tax counsel selected by it and
reasonably approved by the Lessee and furnished at the Lessee's sole expense to
the effect that, as a result of such change or new facts, it is more likely than
not that the position which such Tax Indemnitee or the Lessee, as the case may
be, had asserted in such previous contest, would prevail.

          (e) Claims Barred.  If (A) any Tax Indemnitee fails to give the Lessee
              -------------
written notice pursuant to this Section 6.04 of any claim by any government or
taxing authority for any Tax for which the Lessee is obligated pursuant to this
Section 6.01, (B) as a direct result of such failure the contest of such claim
becomes barred by law and (C) the Lessee furnishes, at the Lessee's expense, an
opinion of counsel selected by the Lessee and reasonably satisfactory to such
Tax Indemnitee to the effect that, had the contest of such claim not become
barred by law, a Reasonable Basis, would have existed for pursuing such contest,
such Tax Indemnitee shall be deemed to have waived its right to any payment by
the Lessee that would otherwise be payable by the Lessee pursuant to this
Section 6.01 in respect of such claim.

          Section 6.05.  Refunds.  When a Tax Indemnitee becomes entitled to
                         -------
receive a refund or credit against Tax of all or any part of any Taxes which the
Lessee shall have paid for such Tax Indemnitee or for which the Lessee shall
have reimbursed or indemnified such Tax Indemnitee, such Tax Indemnitee shall
pay, provided an Event of Default has not occurred and is not continuing, to the
Lessee an amount equal to the amount of such refund or credit less (x) all
payments then due to such Tax Indemnitee under this Article 6, and (y) Taxes
imposed with respect to the accrual or

                                      49
<PAGE>

receipt thereof, including interest received attributable thereto, plus any tax
benefit realized by such Tax Indemnitee as a result of any payment by such Tax
Indemnitee made pursuant to this sentence; provided, however, that such amount
                                           --------  -------
shall not be payable (a) before such time as the Lessee shall have made all
payments or indemnities then due and payable to such Tax Indemnitee under this
Article 6 and (b) to the extent that the amount of such payment would exceed (i)
the amount of all prior payments by the Lessee to such Tax Indemnitee pursuant
to this Article 6 less (ii) the amount of all prior payments by such Tax
Indemnitee to the Lessee pursuant to this Article 6 (any such excess shall be
carried forward to reduce pro tanto any subsequent obligations of the Lessee to
make payments to such Tax Indemnitee pursuant to Section 6.01 hereof). If an
amount payable by any Tax Indemnitee to the Lessee pursuant to this Section 6.02
is not paid when due because of the occurrence and continuation of an Event of
Default, such amount shall be payable by any Tax Indemnitee to the Lessee upon
the Lessee's curing all Events of Default.

          Any subsequent loss of such refund or tax benefit shall be treated as
a Tax subject to indemnification under the provisions of this Article 6 (in the
case of any such tax benefit, subject to Section 6.01(b) but only insofar as
subsections (iv), (vi), (x), (xi), (xiii) and (xiv) thereof would apply).

          Section 6.06.  Reports. In case any report or return is required to be
                         -------
made with respect to any Taxes against which the Lessee is or may be obligated
to indemnify the Indemnities under this Article 6, the Lessee shall, to the
extent it has knowledge thereof, make such report or return, except for any such
report or return that the Tax Indemnitee has notified the Lessee that it intends
to file, in such manner as will show the ownership of the Aircraft in the Owner
Trustee and shall send a copy of the applicable portions of such report or
return to the Tax Indemnitee and the Owner Trustee or will notify the Tax
Indemnitee of such requirement and make such report or return in such manner as
shall be satisfactory to such Tax Indemnitee and the Owner Trustee. The Lessee
will provide such information within the possession or control of the Lessee as
the Tax Indemnitee may reasonably request in writing from the Lessee to enable
the Tax Indemnitee to fulfill its tax filing requirements with respect to the
transactions contemplated by the Operative Agreements (without duplication of
any comparable requirements of the Tax Indemnity Agreement) and any audit
information request arising from any such filing. The Tax Indemnitee will
provide such information within its possession or control as the Lessee may
reasonably require from such Tax Indemnitee to enable the Lessee to fulfill its
tax filing requirements with respect to the transactions contemplated by the
Operative Agreements and any audit information request arising from such filing;
provided that in no event shall any Tax Indemnitee be required to provide copies
- --------
of any of its tax returns.

          Section 6.07.  Survival of Obligations.  The representations,
                         -----------------------
warranties, indemnities and agreements of the Lessee provided for in this
Article 6 and the Lessee's obligations under any and all of them, in each case,
with respect to events or periods prior to the expiration or termination of the
Lease shall survive the expiration or other termination of the Operative
Agreements.

          Section 6.08.  Payment of Taxes.  With respect to any Tax otherwise
                         ----------------
indemnifiable hereunder by the Lessee and applicable to the Aircraft, Airframe,
any Engine or Parts, to the extent

                                      50
<PAGE>

permitted by the applicable federal, state, local or foreign law, the Lessee
shall pay such tax directly to the relevant Taxing authority and file any
returns or reports required with respect thereto to the extent legally entitled
to do so in its own name; provided, however, that the Lessee shall not make any
                          --------  -------
statements or take any action which would indicate that the Lessee or any Person
other than the Owner Trustee or Owner Participant is the owner of the Aircraft,
the Airframe, any Engine or any Part or which would otherwise be inconsistent
with the terms of the Lease or the Tax Indemnity Agreement and the position
thereunder of the Owner Trustee and the Owner Participant.

          Section 6.09.  Reimbursements by Indemnitees Generally.  To the extent
                         ---------------------------------------
the Lessee is required to pay or withhold any Tax imposed on or with respect to
a Tax Indemnitee in respect of the transactions contemplated by the Operative
Agreements, which Tax is not otherwise the responsibility of the Lessee under
the Operative Agreements, or any other written agreements between the Lessee and
such Tax Indemnitee, then such Tax Indemnitee shall pay to the Lessee within 30
days of the Lessee's demand therefor an amount which equals the amount actually
paid by the Lessee with respect to such Taxes.

          Section 6.10.  Forms.  Each Tax Indemnitee agrees to furnish from time
                         -----
to time to Lessee or to such other person as Lessee may designate, at Lessee's
request and, except in respect to Form W-8, Form 1001 or Form 4224, expense,
such duly executed and properly completed forms as may be necessary or
appropriate in order to claim any reduction of or exemption from any withholding
or other Tax imposed by any taxing authority, if (x) such reduction or exemption
is available to such Tax Indemnitee as reasonably determined by such Tax
Indemnitee in good faith, (y) Lessee has provided such Tax Indemnitee with any
information necessary to complete such form not otherwise reasonably available
to such Tax Indemnitee, and (z) with respect to Owner Participant, the Owner
Participant has determined in good faith that furnishing such form could not
have a material adverse impact on the Owner Participant or an Affiliate thereof.

          Section 6.11.  Verification.  At the Lessee's request, the accuracy of
                         ------------
any calculation of amount(s) payable pursuant to this Article 6 shall be
verified by independent public accountants selected by the applicable Tax
Indemnitee and reasonably satisfactory to the Lessee (it being understood, in
the case of a Noteholder Tax Indemnitee, that such Tax Indemnitee's own
independent public accountant shall be reasonably satisfactory to Lessee so long
as such accountant is otherwise reasonably satisfactory to Lessee), and such
verification shall bind the applicable Tax Indemnitee and the Lessee.  In order,
and to the extent necessary, to enable such independent accountants to verify
such amounts, such Tax Indemnitee shall provide to such independent accountants
(for their confidential use and not to be disclosed to the Lessee or any other
person) all information reasonably necessary for such verification.
Verification shall be at the expense of the Lessee, unless such verification
results in an adjustment in the Lessee's favor of $10,000 or more of the amount
of the payment as computed by such Tax Indemnitee, in which case the
verification shall be at the expense of the Tax Indemnitee.

          Section 6.12.  Non-Parties. If a Tax Indemnitee is not a party to this
                         -----------
Agreement, Lessee may require the Tax Indemnitee to agree in writing, in a form
reasonably acceptable to Lessee, to the terms of this Article 6 prior to making
any payment to such Tax Indemnitee hereunder.

          Section 6.13. Foreign Tax On Loan Payments. If an Owner Participant is
                        ----------------------------
incorporated or organized in a country other than the United States or in a
territory, possession or commonwealth of the United States (within the meaning
of the tax law of that foreign jurisdiction) and if as a result thereof any
foreign withholding Taxes are imposed on any Noteholder, then Owner Participant
shall reimburse Lessee for any payments Lessee is required to make to or on
behalf of any Noteholder under this Article 6 as a result of the imposition of
such Taxes. The amount payable by Owner Participant to Lessee shall be an amount
which, after taking into account any such Taxes, any Tax imposed upon the
receipt or accrual by Lessee of such payment by Owner Participant and any tax
benefits or tax savings realized by Lessee with respect to the payment of such
withholding Tax or the payment hereunder, shall equal the amount of Lessee's
payment to or on behalf of such Noteholder.

     negligence of such Indemnitee (other than gross negligence or willful
     misconduct imputed to such person by reason of its interest in the Aircraft

     pursuant to Section 17 thereof, the indemnity provided in Section 7.01(a)
     hereof shall survive for so long as Lessor or the Indenture Trustee shall
     be exercising remedies under such Section 17); provided further, that

     disposition (voluntary or involuntary) by any Noteholder of all or any part
     of its interest in any Equipment Note or the Operative Agreements, other
     than a disposition during the continuance of or as a result of an Event of
     Default;

     maintained by or for the benefit of an Indemnitee which the Lessee is not
     required to maintain at its own cost and expense pursuant to Section 9 of

               (c)   Non-Parties. If an Indemnitee is not a party to this
                     -----------
Agreement, Lessee may require such Indemnitee to agree in writing, in a form
reasonably acceptable to Lessee, to the terms of this Article 7 prior to making
any payment to such Indemnitee under this Article 7.

          Section 7.02.  Notice and Payment.  Each Indemnitee shall give prompt
                         ------------------
written notice to the Lessee of any liability as to which an officer of such
Indemnitee has actual knowledge, for which the Lessee is, or may be, liable
under this Article 7; provided, however, that failure to give such notice shall

not terminate any of the rights of an Indemnitee under this Article 7 and shall
not release Lessee from any of its obligations to indemnify such Indemnitee
hereunder, except to the extent that such failure adversely affects any
applicable defense or counterclaim or otherwise increases the amount the Lessee
would have been liable for in the absence of such failure to provide such
notice.

          Section 7.03. Defense of Claims. The Lessee or its insurers shall have
                        -----------------
the right (in each such case at the Lessee's sole expense) to investigate,
defend (and control the defense of) any such claim for which indemnification is
sought pursuant to this Article 7 (so long as Lessee has agreed in writing
reasonably acceptable to the relevant Indemnitee that Lessee is liable to such
Indemnitee for any Expenses relating to or arising out of the claim for which
indemnification is sought, provided that Lessee will not be so liable to the
                           -------- ----
extent that it is reasonably determined that one or more of the exclusions
contained in Section 7.01(b) would be applicable to such claim) and each
Indemnitee shall cooperate, at Lessee's expense, with all reasonable requests of
the Lessee or its insurers with respect thereto; provided that, without limiting

compromise, any such claim, the Lessee shall not be entitled to assume and
control the defense of or compromise any such claim (A) during the continuance
of any Event of Default, (B) if an actual or potential material conflict of
interest exists making it advisable in the good faith opinion of such Indemnitee
(on the basis of prevailing standards of professional responsibility) for such
Indemnitee to be represented by separate counsel or if such

                                      56

proceeding could in the good faith judgment of such Indemnitee involves the
potential imposition of criminal liability on such Indemnitee or (C) if such
proceeding will involve any non-de minimis risk of the sale, forfeiture or loss
of, or the creation of any Lien (other than Permitted Liens) on the Aircraft,
the Indenture Estate or the Trust Estate (unless the Lessee posts a bond or
other security reasonably acceptable in form and substance to such Indemnitee)
or involve any risk of criminal liability to such Indemnitee. Subject to the
immediately foregoing sentence, where the Lessee or the insurers under a policy
of insurance maintained by the Lessee undertake the defense of an Indemnitee
with respect to such a claim, no additional legal fees or expenses of such
Indemnitee in connection with the defense of such claim shall be indemnified
hereunder unless the fees or expenses were incurred at the written request of
the Lessee or such insurers. Subject to the requirement of any policy of
insurance applicable to a claim, an Indemnitee may participate at its own
expense at any judicial proceeding controlled by the Lessee or its insurers
pursuant to the preceding provisions, to the extent that such party's
participation does not, in the reasonable opinion of the independent counsel
appointed by the Lessee or its insurers to conduct such proceedings, interfere
with the defense of such claim (it being agreed that the making of copies,
giving notice of proceedings and the like shall not be considered interference);
and such participation shall not constitute a waiver of the indemnification
provided in this Section 7.03; provided that, the reasonable fees and expenses
                               --------
of such Indemnitee's counsel shall be paid by the Lessee if any of the
circumstances described in clauses (A)-(C) of the second preceding sentence
exists. Nothing contained in this Article 7 shall be deemed to require an
Indemnitee to contest any Expense or to assume responsibility for or control of
any judicial proceeding with respect thereto. No Indemnitee shall enter into any
settlement or other compromise with respect to any claim described in this
Section 7.03 (other than any claim involving potential criminal liability)
without the prior written consent of the Lessee, unless such Indemnitee waives
its right to be indemnified under this Article 7 with respect to such claim or
unless an Event of Default is continuing. The Lessee shall not enter into any
settlement or compromise with respect to which the Lessee has not agreed to
indemnify such Indemnitee to such Indemnitee's satisfaction or which admits any
criminal violation, gross negligence or willful misconduct on the part of any
Indemnitee without the prior written consent of such Indemnitee.

          Section 7.04.  Insured Claims.  Notwithstanding any other provision of
                         --------------
this Article 7 to the contrary, in the case of any Expense indemnified by the
Lessee hereunder which is covered by a policy of insurance maintained by the
Lessee (or a Permitted Sublessee) pursuant to Section 9 of the Lease or
otherwise, each relevant Indemnitee shall cooperate with the insurers in the
exercise of their rights to investigate, defend or compromise such claim as may
be required to retain the benefits of such insurance with respect to such claim.

          Section 7.05.  Subrogation.  To the extent that an Expense indemnified
                         -----------
by the Lessee under this Article 7 is in fact paid in full by the Lessee and/or
an insurer under a policy of insurance maintained by the Lessee, the Lessee
and/or such insurer, as the case may be, shall, so long as no Specified Default
or Event of Default has occurred and is continuing, be subrogated to the extent
of such payment to the rights and remedies of the Indemnitee on whose behalf
such Expense was paid with respect to the transaction or event giving rise to
such Expense (other than the rights and remedies in respect of insurance
policies maintained by such Indemnitee and other than the rights

                                      57
<PAGE>

of the Trust Company or the Owner Trustee and remedies against the Owner
Participant under the Trust Agreement). Should an Indemnitee receive any refund
(except under insurance policies paid for by such Indemnitee), in whole or in
part, with respect to any Expense paid in full by the Lessee hereunder, it shall
promptly pay over the amount refunded (but not an amount in excess of the amount
Lessee and/or such insurer has paid to such Indemnitee in respect of such
Expense) to the Lessee unless a Specified Default or an Event of Default shall
have occurred and be continuing (or would have occurred and be continuing if the
Owner Participant had given the notice specified in Section 16(a) of the Lease),
in which case, provided that Lessee shall have paid such Indemnitee all amounts
required under this Article 7 or under any other Operative Agreement, such
amounts shall be paid over to Owner Trustee (or, so long as the Indenture shall
not have been discharged in accordance with its terms, to the Indenture Trustee)
to hold as security for Lessee's obligations under the Lessee Documents or, if
requested by Lessee, applied to satisfy such obligations.

          Section 7.06.  Information.  Subject to Section 7.04, Lessee will
                         -----------
provide the relevant Indemnitee with such information, not within the control of
such Indemnitee, as is in Lessee's control or is reasonably available to Lessee,
which such Indemnitee may reasonably request, and will otherwise cooperate with
such Indemnitee, so as to enable such Indemnitee to fulfill its obligations
under Section 7.03 and to control or participate in any proceeding to the extent
permitted by Section 7.03.  The Indemnitee shall supply Lessee with such
information, not within the control of Lessee, as is in such Indemnitee's
control or is reasonably available to such Indemnitee, which Lessee may
reasonably request to control or participate in any proceeding to the extent
permitted by Section 7.03.

          Section 7.07.  Survival of Obligations.  The indemnities and
                         -----------------------
agreements of the Lessee provided for in this Article 7 shall survive the
expiration or other termination of this Agreement.

          Section 7.08.  Effect of Other Indemnities.  The Lessee's obligations
                         ---------------------------
under this Article 7 shall be those of a primary obligor whether or not the
Person indemnified shall also be indemnified with respect to the same matter
under the terms of this Agreement, or any other document or instrument, and the
Person seeking indemnification from the Lessee pursuant to any provision of this
Agreement may proceed directly against the Lessee without first seeking to
enforce any other right of indemnification.

          Section 7.09.  Waiver of Certain Claims.  The Lessee hereby waives and
                         ------------------------
releases any Expense now or hereafter existing against any Indemnitee arising
out of death or personal injury to personnel of the Lessee, loss or damage to
property of the Lessee, or the loss of use of any property of the Lessee, which
results from or arises out of the condition, use or operation of the Aircraft
during the Term, including, without limitation, any latent or patent defect
whether or not discoverable.

          Section 7.10.  Certain Limitations.  The Lessee does not guarantee and
                         -------------------
nothing in the general indemnification provisions of this Article 7 shall be
construed as a guarantee (or an indemnification) by the Lessee (i) that the
principal of, premium, if any, or interest on any Equipment Note will be paid or
(ii) with respect to the residual value of the Aircraft or any part thereof.

          Section 7.11.  Certain Transfers.  If the Owner Participant (i) makes
                         -----------------
any claim for payment as a result of the indemnity provided by the Lessee in
Section 6.01(a)(x) or 7.01(a)(vii), and (ii) such claim is the result of the
direct or indirect acquisition or holding of an Equipment Note by an ERISA Plan,
established or maintained by Owner Participant or any entity that is treated as
a single employer with Owner Participant under Section 414(b), (c), (m) or (o)
of the Code (an "ERISA Affiliate") or as to which Owner Participant or any ERISA
Affiliate of Owner Participant contributed or is a member, the Lessee shall have
the right, upon 30 days notice to the Owner Participant, to purchase the
Beneficial Interest (and in connection with such purchase, the Lessee shall give
the Loan Participant and the Indenture Trustee 10 days notice of such purchase
and in connection with any such transfer of Beneficial Interest, the Owner
Participant and the Lessee shall comply with Section 5.01(c) (other than (v)
clauses (i) and (v) of the first proviso to such Section, (w) clause (a) of the
third sentence of such Section, (x) the proviso to such third sentence, (y)
clause (c) of the third sentence of such Section to the extent that it requires
the making of the representations or covenants relating to those contained in
clause (viii) of Section 5.01(a) and in clause (a) of the third sentence of
Section 5.01(c) and (z) the seventh sentence of Section 5.01(c)), provided that,
                                                                  -------- ----
the Owner Participant shall not be obligated to proceed with any such transfer
of Beneficial Interest if the Lessee cannot comply with the requirements of a
transferee), on a Termination Date specified in such notice, for a price equal
to the higher of (1) the Owner Participant's Share of Termination Value and (2)
the Owner Participant's Share of FMV.  In connection with any such purchase, the
Lessee shall pay all unpaid Supplemental Rent (including payment of such
indemnity claim) due on or before such Termination Date.  All reasonable fees
and expenses incurred by Owner Participant, Indenture Trustee, any Noteholder or
Owner Trustee in connection with such transfer shall be promptly paid by Lessee.
The Lessee shall not have the right to purchase the Beneficial Interest in any
instance pursuant to the foregoing sentence in the event the Owner Participant
waives any claim for payment it may have in such instance pursuant to clause (i)
above.  For purposes of this Section 7.11, "Owner Participant's Share of
Termination Value" means the excess of (w) the Termination Value as of such
Termination Date, over (x) the aggregate principal amount of Equipment Notes
that would be outstanding on such Termination Date (and accrued interest thereon
at the Applicable Rate) assuming all payments of Basic Rent payable on or prior
to such Termination Date shall have been paid when due, and "Owner Participant's
Share of FMV" means the Fair Market Sales Value of the Aircraft as of such
Termination Date, determined in accordance with the definition thereof but
assuming (y) that the Aircraft is subject to the Lease, the Indenture, the
indebtedness evidenced by the Equipment Notes and the other Operative Agreements
and (z) that the violation giving rise to such indemnity claim has been cured.
Nothing in this Section 7.11 shall affect the obligation of the Lessee to make
any payment of Supplemental Rent or Basic Rent due on or prior to such
Termination Date, the payment of which amount is a condition precedent to the
exercise by the Lessee of its rights under this Section 7.11; provided that, the
                                                              -------- ----
advance portion, if any, of Basic Rent payable on such Termination Date shall,
in connection with any purchase under this Section 7.11, be deemed to be paid
following such purchase, and accordingly the Owner Participant shall have no
interest in such advance portion of Basic Rent following such purchase.

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

connection with any amendment, supplement, waiver or consent (whether or not
entered into) under this Agreement or any other Operative Agreement or document
or instrument delivered pursuant to any of them, which amendment, supplement,
waiver or consent is required by any provision of any Operative Agreement
(including any adjustment pursuant to Section 3(d) of the Lease) or is required
by Applicable Law or necessitated by the action or inaction of the Lessee or
occurs after an Event of Default has occurred and is continuing or is requested
by or consented to by the Lessee; provided, however, that if such amendment,
                                  --------  -------
supplement, waiver or consent is not requested by the Lessee, the requesting
parties (other than the Lessee) shall pay all such costs and expenses on behalf
of the Lessee (without any right of reimbursement or indemnification from the
Lessee).

                                  REFINANCING

          Section 13.01.  Refinancing
                          -----------

         (a) Subject to the terms and conditions of this Section 13.01, on any
date on or after the fifth anniversary of the Delivery Date (except in the case
of a refinancing which occurs after a Noteholder has requested the payment of
(x) any Increased Costs pursuant to Section 2.14(a) of the Indenture or (y) any
amounts pursuant to Article 6 hereof in respect of withholding Taxes, in which
case such refinancing may be requested by the Lessee at any time), the Lessee
may request the Owner Participant to participate in two refinancings in whole
but not in part, of the Equipment Notes prior to the end of the Basic Term (a
"Refinancing").  Such Refinancing may be placed in either the private or public
markets and shall be denominated in Dollars and shall be on terms reasonably
satisfactory to the Owner Participant.  The Owner Participant will agree to
negotiate promptly in good faith to conclude an agreement with the Lessee as to
the terms of any such Refinancing transaction (including the terms of any debt
to be issued in connection with such

                                      63
<PAGE>

refinancing and the documentation to be executed in connection therewith).
Without the prior written consent of the Owner Participant, the prospectus and
other offering materials relating to any Refinancing in the form of a public
offering shall not identify the Owner Participant and shall not include any
financial statements of the Owner Participant or any Affiliate thereof. In
connection with any such Refinancing in the form of a public offering, the
Lessee shall indemnify the Owner Participant in a manner satisfactory to it for
any liabilities under federal, state or foreign securities laws resulting from
such offering. The aggregate principal amount of the new Equipment Notes issued
in connection with any Refinancing shall be the same as the aggregate principal
amount outstanding on the Equipment Notes being refinanced.

          (b) Notwithstanding anything herein to the contrary, no Refinancing
will be permitted unless the Owner Participant and the Indenture Trustee shall
have received at least 15 days' prior written notice of the scheduled closing
date of such Refinancing and the Owner Participant shall have been provided such
longer period as it shall have required for a reasonable opportunity to review
the relevant documentation and the Owner Participant shall have determined in
good faith that neither it nor the Owner Trustee shall suffer any loss or
expense or bear any increased risk as a result of such Refinancing (including,
without limitation, any risk with respect to taxes or other adverse consequences
to the Owner Participant including the application of Revenue Procedures 75-21
and 75-28 and Section 467 of the Code) for which it has not been or will not
have been indemnified in a manner satisfactory in form and substance to the
Owner Participant.

          Prior to the consummation of any Refinancing pursuant to this Section
13.01, the Owner Participant and the Lessee shall agree upon a schedule setting
forth each installment of Basic Rent and setting forth Termination Values
payable pursuant to the Lease as a result of the Refinancing in accordance with
Section 3(d) of the Lease, and thereafter the amounts set forth in such schedule
shall become the amounts payable under the Lease.  Upon the consummation of the
Refinancing, the evidence of indebtedness issued pursuant to the Refinancing
shall be considered "Equipment Notes" for purposes of this Agreement and the
Lease.

          (c) Notwithstanding the foregoing, the Owner Participant shall have no
obligation to proceed with any Refinancing transaction as contemplated by this
Section 13.01 unless the Lessee provides an indemnity on an After Tax Basis to
the Owner Trustee and the Owner Participant by agreement in form and substance
satisfactory to each of them (provided that Taxes are excluded from such
                              --------
indemnity), for any liability, obligation (other than, in the case of the Owner
Trustee, the non-recourse obligation to pay principal and interest in respect of
the refinanced indebtedness), cost or expense (including, without limitation,
reasonable attorneys' fees and Make-Whole Amount or other amounts due under the
Indenture).

          (d) Without the prior written consent of the Owner Participant, no
such refinancing shall (1) cause the aggregate principal amount of the
indebtedness to be substituted for the Equipment Notes to exceed the aggregate
principal amount of the then outstanding Equipment Notes, (2) cause the weighted
average life of such indebtedness to be longer than the remaining weighted
average life of the then outstanding Equipment Notes, or (3) cause the date of
maturity of such indebtedness to be later than the date of maturity of the
Equipment Notes being refinanced.

          (e) Subject to the foregoing provisions of this Section 13.01, each
party agrees to take or cause to be taken all requested action, including,
without limitation, the execution and delivery of any documents and instruments,
including, without limitation, amendments or supplements to the Lease, which may
be reasonably necessary or desirable to effect such Refinancing, including, in
the case of the Owner Participant, direction to the Owner Trustee by the Owner
Participant to prepay the Equipment Notes then outstanding; provided, however,
                                                            --------  -------
that such Refinancing shall be subject to the satisfaction of each of the
following conditions:

              (i)  Payment shall have been made with respect to principal,
     accrued interest, Make-Whole Amount, if any, and all other sums due and
     owing on the Equipment Notes payable under the Indenture;

             (ii)  Payment in full of all other amounts then due and owing by
     the Lessee under this Agreement, the Indenture, the Lease, the Trust
     Agreement, and the Equipment Notes then outstanding shall have been made by
     the Lessee;

            (iii)  Such party shall have received such opinions of counsel
     (including, without limitation, an opinion received by the Owner
     Participant from independent tax counsel selected by Owner Participant and
     reasonably satisfactory to the Lessee that such Refinancing shall not
     result in any, or the risk of any, adverse tax consequences to such Owner
     Participant, unless the Lessee shall have provided, or caused to be
     provided, an indemnity in respect thereof satisfactory in form and
     substance to the Owner Participant), certificates and other documents as it
     may reasonably request, each in form and substance reasonably satisfactory
     to such party;

             (iv)  All authorizations, approvals and consents which in the
     reasonable judgment of the Owner Participant are necessary for such
     Refinancing shall have been obtained;

              (v)  No Specified Default shall exist or would occur immediately
     after giving effect to such Refinancing;

             (vi)  In the event the Lessee shall not prohibit the purchase of
     the Refinancing loan certificates by, or with the assets of, an ERISA Plan,
     the Lessee will permit the placement of the Refinancing loan certificates
     with an ERISA Plan only if either (A) if such placement is in the form of
     pass-through certificates, the sole underwriter or the manager or co-
     manager of the underwriting syndicate or the selling or placement agent of
     such pass-through certificates represents to the Lessee that it has a
     prohibited transaction exemption from the U.S. Department of Labor with
     respect to pass-through certificates (such as Prohibited Transaction
     Exemption 89-88 or any other comparable exemption) or (B) purchasers of the
     Refinancing loan certificates (or if the Refinancing involves the issuance
     and sale of pass-through certificates, purchasers of such pass-through
     certificates) provide a representation (which may be in the form of a
     deemed representation) regarding their source of funds used in acquiring
     the Refinancing loan certificates (or such pass-through certificates, as
     the case may be) and, if such purchasers represent that they are using
     funds of an ERISA Plan in acquiring the Refinancing loan certificates (or
     such pass-through certificates, as the case may

                                      65

     be), such purchasers further represent that they are relying on a
     prohibited transaction exemption from the U.S. Department of Labor with
     respect to their purchase and holding of the Refinancing loan certificates
     (or such pass-through certificates, as the case may be). The reliance on
     any such exemption will not be conditional on the Owner Participant's
     representation concerning its party in interest or other status with
     respect to ERISA Plans; and

              (vii)  The Lessee shall pay all costs and expenses (including
     legal fees and disbursements) incurred in connection with any proposed or
     actually consummated Refinancing.

          Section 15.05.  Concerning the Owner Trustee and Indenture Trustee.
                          --------------------------------------------------
Each of Trust Company and Indenture Trustee is entering into this Agreement
solely in its capacities (except to the extent otherwise expressly indicated),
in the case of Trust Company, not in its individual capacity but solely as Owner
Trustee under the Trust Agreement, in the case of Indenture Trustee, not in its
individual capacity but solely as Indenture Trustee under the Indenture, and
except as otherwise expressly provided in this Agreement or in the Lease, the
Indenture or the Trust Agreement, neither Trust Company nor Indenture Trustee
shall be personally liable for or on account of its statements, representations,
warranties, covenants or obligations under this Agreement; provided, however,
                                                           --------  -------
that each of Trust Company and Indenture Trustee accepts the benefits running to
it under this Agreement, and each agrees that (except as otherwise expressly
provided in this Agreement or any other Operative Agreement to which it is a
party) it shall be liable in its individual capacity for (a) its own gross
negligence or willful misconduct (whether in its capacity as trustee or in its
individual capacity), (b) any breach of representations and warranties or any
breach of covenants made in its individual capacity pursuant to or in connection
with this Agreement or the other Operative Agreements to which it is a party,
(c) any breach, in the case of the Owner Trustee, of its covenants contained in
Sections 4.01 and 6.03 of the Indenture, (d) the failure to use ordinary care in
receiving, handling and disbursing funds, (e) in the case of the Owner Trustee,
Lessor's Liens attributable to it in its individual capacity, (f) in the case of
the Indenture Trustee, Indenture Trustee's Liens, and (g) taxes, fees or other
charges on, or based on, or measured by, any fees, commissions or compensation
received by it in connection with the transactions contemplated by the Operative
Agreements.

          Section 15.06.  Severability.  Any provision of this Agreement which
                          ------------
is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions, and any such
prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

         Section 15.07.  Certain Limitations on Reorganization.  The Indenture
                         -------------------------------------
Trustee, the Loan Participant and each Noteholder each agrees that, if (i) the
Owner Trustee becomes or all or any part of the Lessor's Estate or the trust
created by the Trust Agreement becomes the property of, a debtor subject to the
reorganization provisions of the Bankruptcy Code or any other applicable
bankruptcy or insolvency statutes, (ii) pursuant to any such reorganization
provisions, the Owner Participant is held to have recourse liability to the
Indenture Trustee, any Noteholder, the debtor, the Owner Trustee or the trustee
of the debtor directly or indirectly on account of any amount payable as Make-
Whole Amount, principal or interest on the Equipment Notes, or any other amount
payable on any Equipment Note that is provided in the Operative Agreements to be
nonrecourse to the Owner Participant and (iii) any Noteholder or the Indenture
Trustee actually receives any Recourse Amount which reflects any payment by the
Owner Participant on account of (ii) above, then such Noteholder or the
Indenture Trustee, as the case may be, shall promptly refund to the Owner
Participant such Recourse Amount.  For purposes of this Section 15.07, "Recourse
Amount" means the amount by which the portion of such payment by the Owner
Participant on account of clause (ii) above received by such Noteholder or the
Indenture Trustee exceeds the amount which would have been received by such
Noteholder or the Indenture Trustee if the Owner Participant had not become
subject to the recourse liability referred to in (ii) above.  Nothing contained
in this Section shall

                                      67
<PAGE>

prevent the Loan Participant, any Noteholder or the Indenture Trustee from
enforcing any individual obligation (and retaining the proceeds thereof) of the
Owner Participant under this Agreement or, any other Operative Agreement to the
extent herein or therein provided, for which the Owner Participant has expressly
agreed by the terms of this Agreement to accept individual responsibility.

CASE IN ACCORDANCE WITH THIS SECTION 15.08(c), SHALL CONSTITUTE VALID AND
EFFECTIVE PERSONAL SERVICE UPON SUCH PARTY, AND EACH PARTY HERETO (OTHER THAN

          (a)  If, for the purposes of obtaining judgment in, or enforcing the
judgment of, any court, it is necessary for any Person to convert a sum due
hereunder or under any other Operative Agreement in Dollars into another
currency (the "Judgment Currency"), the rate of exchange used shall be that at
               -----------------
which in accordance with normal banking procedures such Person could purchase
Dollars with the Judgment Currency on the Business Day preceding that on which
final judgment is given or the order of enforcement made.

          (b)  The obligation of the Lessee in respect of any sum due from it to
any Person hereunder or under any other Operative Agreement shall,
notwithstanding any judgment or order of enforcement in such Judgment Currency,
be discharged only to the extent that on the Business Day following that on
which final judgment is given or the order of enforcement made, such Person may
in accordance with normal banking procedures purchase Dollars with the Judgment
Currency; if the Dollars so purchased are less than the sum originally due to
such Person in Dollars, the Lessee agrees, as a separate obligation and
notwithstanding any such judgment or order of enforcement, to indemnify such
Person against such loss attributable to any of its obligations hereunder or
under any other Operative Agreement, and if the Dollars so purchased exceed the
sum originally due from the Lessee, in Dollars, such Person shall remit to the
Lessee such excess.  Any additional amount due from the Lessee under this

judgment or order of enforcement being obtained for any other sums due under or
in respect of this Agreement or any other Operative Agreement.

of this Agreement or any of the other Operative Agreements, or (without in any
way limiting any obligations of the Lessee otherwise expressly provided for in
any Operative Agreement) impose any obligation on the Lessee in respect of the
matters discussed therein or constitute or be deemed to constitute a waiver of

GENERAL PROVISIONS

          The following terms shall have the following meanings for all purposes
of the Operative Agreements (as defined below), unless otherwise defined in an
Operative Agreement or the context thereof shall otherwise require.  In the case
of any conflict between the provisions of this Appendix and the provisions of
any Operative Agreement, the provisions of such Operative Agreement shall
control the construction of such Operative Agreement.

          Unless the context otherwise requires, (i) references to agreements
shall be deemed to mean such agreements as amended and supplemented from time to
time, and any agreement, instrument or document entered into in substitution or

documents, certificates and statements of government officials and other papers
as I have deemed necessary or advisable as a basis for such opinions.

     Based upon the foregoing, I am of the opinion that:

     1.   The Lessee is a corporation duly organized and validly existing in
good standing under the laws of the State of Delaware and has the corporate
power and authority to own or hold under lease its properties and conduct its
business as presently conducted and to enter into and perform its obligations
under the Lessee's Agreements.  The Lessee is an "air carrier" within the
meaning of the Transportation Code and a holder of a certificate under Section
41102(a) of the Transportation Code and a "citizen of the United States" within
the meaning of Section 40102(a)(15) of the Transportation Code holding an "air
carrier operating certificate" issued under Chapter 447 of the Transportation
Code for aircraft capable of carrying ten or more individuals or 6,000 pounds or
more of cargo, and each such certificate is in full force and effect.  The
Lessee is duly qualified to do business as a foreign corporation and in good
standing in each jurisdiction where the activities of the Lessee require such
qualification except where the failure to so qualify would not have a material
adverse effect on the Lessee or the ability of the Lessee to perform its
obligations under the Lessee's Agreements.  The Lessee's chief executive office
(as such term is defined in the Uniform Commercial Code as in effect in the
State of North Carolina) is at 2801 Slater Road, Morrisville, North Carolina
27560.

     2.   The execution, delivery and performance by the Lessee of the Lessee's
Agreements do not require the approval or consent of, or the giving of notice
to, any trustee, stockholders or holders of any indebtedness or obligations of
the Lessee (except for such consents or approvals as have been obtained on or
prior to the Delivery Date), and neither the execution and delivery by the
Lessee thereof nor the performance by the Lessee of the transactions
contemplated thereby nor compliance by the Lessee with any of the terms and
provisions thereof will contravene any applicable law of the State of Delaware
or the United States of America applicable to or binding upon the Lessee (other
than the securities or Blue Sky laws of the various states, as to which I
express no opinion), or any of its properties, or contravene or result in any
breach of, or constitute any default under or result in the creation of any Lien
(other than as permitted under the Operative Agreements) upon any property of
the 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 the Lessee is a party or by which
the Lessee or any of its property may be bound or affected (except for such
conflicts, breaches or defaults or liens, charges or encumbrances, that, singly
or in the aggregate, would not have material adverse effect on the Lessee's
ability to perform its obligations under the Lessee's Agreements).

     3.   The execution, delivery and performance of the Lessee's Agreements
have been duly authorized by all necessary corporate action on the part of the
Lessee, and the Lessee's Agreements have been duly executed and delivered by the
Lessee.

     4.   There are no pending or, to our knowledge, threatened actions, suits,
or proceedings before any court or administrative agency or arbitration against
the Lessee or involving the Lessee
<PAGE>

that question the validity of any of the Lessee's Agreements or that is required
to have been disclosed in the Lessee's Annual Report on Form 10-K filed for the
year ended December 31, 1998, or any subsequent Quarterly Report on Form 10-Q or
Current Report on Form 8-K, except such as are therein disclosed.

     No opinion is expressed herein as to state securities laws or other laws
other than the General Corporation Law of the State of Delaware and the federal
laws of the United States.

     This opinion is furnished by me as counsel to the Lessee to you as parties
to the Participation Agreement and is solely for your benefit.

                                         Very truly yours,

     Re:  Lease Financing of One Canadair Regional Jet
          Series 200ER Aircraft -- U.S. Registration No. N583ML
          -----------------------------------------------------


Ladies and Gentlemen:

     We have acted as special New York counsel for Midway Airlines Corporation,
a Delaware corporation (the "Lessee"), in connection with the Participation
Agreement [N583ML] dated as of August 10, 1999, among the Lessee; Polaris
Holding Company, as Owner Participant; First Union Trust Company, National
Association ("FUTC"), as Owner Trustee; Canadian Regional Aircraft Finance
Transaction No. 1 Limited, as Loan Participant; and Allfirst Bank, as Indenture
Trustee. Capitalized terms used herein and not otherwise defined herein shall
have the meanings set forth or referred to in the Participation Agreement.  For
purposes hereof, "Documents" shall be a collective reference to the
Participation Agreement, the Lease, Lease Supplement No. 1, Purchase Agreement
Assignment, the Engine Warranty Assignment, the Residual Agreement, the Return
Condition Agreement and the Tax Indemnity Agreement.

     This opinion is furnished to you pursuant to Section 3.01(b)(xix)(A)(II) of
the Participation Agreement.

     In rendering this opinion, we have examined the Documents and such other
Operative Agreements as are necessary in order to give the opinions expressed
herein.  We have further examined and relied upon the accuracy of original,
certified, conformed, photographic or telecopied copies of such records,
agreements, certificates, certificates of public officials and such other
documents, and have made an investigation of such laws, as we have deemed
necessary and appropriate for the purpose of rendering this opinion.  As to
certain questions of fact material to our opinions, we have relied solely upon
the accuracy of the statements, representations and warranties made in the
Documents and such other Operative Agreements and we have made no independent
investigation or inquiry with respect to such factual matters.
<PAGE>

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

     1.   Each of the Documents constitutes a legal, valid and binding
obligation of the Lessee, enforceable against the Lessee in accordance with its
terms.

     2.   The execution and delivery by the Lessee of the Documents, the
consummation by the Lessee of the transactions contemplated thereby and the
compliance by the Lessee with any of the terms and provisions thereof do not
contravene any applicable federal law of the United States or any applicable law
of New York.

     3.   Except for the filings with the FAA referred to in paragraph 4 below,
the execution and delivery by the Lessee of the Documents and the consummation
by the Lessee of the transactions contemplated thereby do not require the
consent or approval of, or the giving of notice to, or the registration,
recording or filing of any document with, or the taking of any other action with
respect to any authority or agency of the federal government of the United
States of America or the State of New York.

     4.   The Lease as supplemented by Lease Supplement No. 1 thereto and the
Indenture as supplemented by Indenture Supplement No. 1 thereto are in due form
for filing in accordance with Subtitle VII of Title 49 of the United States Code
(the "Act").  The Indenture as supplemented by Indenture Supplement No. 1
thereto will create, for the benefit of the Indenture Trustee, a valid security
interest in the Indenture Estate identified therein.  Except for the filings
with the FAA referred to in the opinion dated today and addressed to you of
Crowe & Dunlevy, the filing of the Uniform Commercial Code financing statements
referenced in Section 3.01(m) and (n) of the Participation Agreement, which
filings we assume have been duly effected and are adequate for their intended
purpose (and subject to the timely filings in the future of continuation
statements with respect to such financing statements), and the taking of
possession by the Indenture Trustee of the original of the Lease and Lease
Supplement No. 1, each with a chattel paper receipt attached, no recording or
filing in the United States of America of any of the Operative Agreements, nor
any other action, is necessary or advisable in order to establish and perfect in
the United States of America, the Owner Trustee's rights and interest in the
applicable Aircraft as against the Lessee or any third party, or the mortgage
and security interest of the Indenture Trustee under the Indenture on the
Aircraft, the Lease or the other property included in the Indenture Estate in
favor of the Indenture Trustee as against the Lessee, the Owner Trustee or any
third party.

     5.   The Participation Agreement, the Lease, the Lease Supplement No. 1,
the Indenture, the Indenture Supplement No. 1 and the Equipment Notes (the
"Owner Trustee Instruments") constitute legal, valid and binding obligations of
FUTC, to the extent any of such Owner Trustee Instruments were entered into by
FUTC in its individual capacity, and the Owner Trustee, or both, as the case may
be, enforceable against FUTC or the Owner Trustee, or both, as the case may be,
in
<PAGE>

accordance with the terms of such agreements, and the holders of the Equipment
Notes are entitled to the benefits of the Indenture.

     6.   The Participation Agreement and the Indenture (the "Indenture Trustee
Documents") constitute legal, valid and binding obligations of the Indenture
Trustee, enforceable against the Indenture Trustee in accordance with their
respective terms.

     7.   So long as the Lessee continues to be a "citizen of the United
States," as defined in Section 40102 of Title 49 of the United States Code,
holding an air carrier operating certificate issued by the Secretary of
Transportation pursuant to Chapter 447 of Title 49 of the United States Code for
aircraft capable of carrying 10 or more individuals or 6,000 pounds or more of
cargo, the Owner Trustee, as lessor under the Lease, and the Indenture Trustee,
as assignee of the Owner Trustee's rights under the Lease pursuant to the
Indenture, would be entitled to the benefits of Section 1110 of the Bankruptcy
Code ("Section 1110") with respect to the Aircraft.

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

     A.   The foregoing opinions are expressly limited to matters under and
governed by the internal laws of the State of New York and applicable federal
laws of the United States of America, except that we express no opinion as to
the securities law of any state, including the State of New York.  Our opinion
in paragraph 2 above as to the contravention of certain laws, rules and
regulations is based upon such examination of laws and regulations as in our
judgment was necessary and appropriate for the purpose of such opinion.

     B.   The foregoing opinions regarding the enforceability of the Operative
Agreements against any of the parties thereto are subject to the following:

          (i) The enforceability of any of the Operative Agreements may be
          limited or affected by (a) bankruptcy, insolvency, reorganization,
          moratorium, liquidation, rearrangement, probate, conservatorship,
          fraudulent transfer, fraudulent conveyance and other similar laws
          (including court decisions) now or hereafter in effect and affecting
          the rights and remedies of creditors generally or providing for the
          relief of debtors, (b) the refusal of a particular court to grant (1)
          equitable remedies, including, without limiting the generality of the
          foregoing, specific performance and injunctive relief or (2) a
          particular remedy sought by the Owner Trustee under the Lease or by
          the Indenture Trustee under the Indenture as opposed to another remedy
          provided for therein or another remedy available at law or in equity,
          but which does not in our opinion make such remedies inadequate for
          the practical realization of the benefits intended to be provided
          thereby, (c) general principles of equity (regardless of whether
          enforcement is sought in a proceeding in equity or at law) and (d) the
          refusal of a federal court to grant jurisdiction in connection with
          any suit commenced relating to the Operative Agreements.
<PAGE>

          (ii) In rendering the foregoing opinions, we express no opinion as to
          the enforceability of provisions of any of the Operative Agreements
          (a) purporting to waive or affect rights, claims, defenses or other
          benefits bestowed by law, including without limitation the right to
          receive notices, to the extent that any of the same cannot be waived
          or affected or (b) relating to indemnities to the extent prohibited by
          public policy or limited by federal or state securities laws or which
          might require indemnification for losses or expenses caused by gross
          negligence, willful misconduct, fraud or illegality of an indemnified
          party, or the exercise of rights and remedies with respect to the
          Aircraft other than in a commercially reasonable manner or as
          otherwise provided in the Uniform Commercial Code or other applicable
          law.

          (iii)  We note that the enforceability of specific provisions of the
          Operative Agreements may be subject to standards of reasonableness,
          care and diligence and "good faith" limitations and obligations such
          as those provided in Sections 1-102(3) and 1-203, of the Uniform
          Commercial Code and similar applicable principles of common law and
          judicial decisions.

          (iv) We express no opinion with respect to compliance with the anti-
          fraud provisions of applicable federal rules or regulations.

     C.   With respect to the opinion given in paragraph 4 above as to the
creation of a security interest in the Indenture Estate, we express no opinion
as to the creation of any security interest in any portion of the Indenture
Estate other than (I) that portion of the Indenture Estate consisting of the
Aircraft, (II) that portion of the Indenture Estate (except for the Aircraft)
which is not excluded by Section 9-104 of the Uniform Commercial Code of any
relevant jurisdiction and (III) if possession or control and dominion or both by
the Indenture Trustee is required or necessary, such portion of the Indenture
Estate as has been deposited with the Indenture Trustee pursuant to the
Indenture, or which possession or control and dominion or both, has otherwise
effectively occurred.

     D.   The foregoing opinions, to the extent they address the creation and
perfection of a security interest in any portion of the Indenture Estate are
further subject to the following:  we have made no examination of, and we
express no opinion as to, (a) the title of any person to the Indenture Estate or
any portion thereof, (b) the value of any security granted to the Indenture
Trustee and (c) the priority of any such security interest.

     E.   We have assumed the due authorization, execution and delivery of the
Operative Agreements by each of the parties thereto (including the Lessee) and
that each of such parties has the full power, authority and legal right to
execute, deliver and perform such documents.

     F.   Except to the extent expressly set forth in paragraphs 1, 5 and 6, we
have assumed that each of the Operative Agreements is enforceable against each
of the parties thereto.
<PAGE>

     G.   With respect to the opinion given in paragraph 5, our opinion is
subject to limitations of Delaware law applicable to FUTC and the Owner Trustee,
as to which we express no opinion.

     H.   With respect to the opinion given in paragraph 6, our opinion is
subject to limitations of Maryland law applicable to Allfirst Bank or the
Indenture Trustee, as the case may be, as to which we express no opinion.

     I.   We have assumed the genuineness of all signatures, the authenticity of
all documents submitted to us as originals and the conformity to the originals
of all documents submitted to us as copies, which facts we have not verified
independently.

     J.   We express no opinion as to whether the Lease constitutes a "true
lease."

     K.   We have assumed that the Operative Agreements and the transactions
contemplated thereby are not within the prohibitions of Section 406 of the
Employee Retirement Income Security Act of 1974.

     L.   With respect to the opinion given in paragraph 7, we express no
opinion as to the availability of the benefits of Section 1110 of the Bankruptcy
Code to any Replacement Aircraft or Replacement Engine.

     M.   In giving the foregoing opinion, we have relied upon the opinions
delivered to you today of Crowe & Dunlevy with respect to the matters set forth
therein.  Our opinion is subject to all applicable qualifications and exceptions
(except for those set forth in clauses (i) (subject however to paragraph A
above) and (ii) thereof set forth in such opinion).

     The opinions expressed herein are solely for the benefit of, and may only
be relied upon by, the named addressees in connection with the transactions
contemplated by the Participation Agreement.  This opinion may not be furnished
or relied upon by any other person without the prior written consent of this
Firm. We make no undertaking to amend or supplement such opinions as facts and
circumstances come to our attention or changes in the law occur which could
affect such opinions.


                                    Very truly yours,

                      U.S. Registration No. N583ML
             -----------------------------------------------



Ladies and Gentlemen:

     We have acted as special Maryland counsel to Allfirst Bank, a Maryland
state-chartered commercial bank (in its individual capacity such bank being
referred to herein as "Allfirst" and, when acting not in its individual capacity
but solely as trustee being referred to herein as the "Indenture Trustee"), in
connection with the execution and delivery by the Indenture Trustee of (i) the
Participation Agreement [N583ML], dated as of August 10, 1999, among Midway
Airlines Corporation, as lessee (the "Lessee"), Polaris Holding Company, as
owner participant (the "Owner Participant"), First Union Trust Company, National
Association, not in its individual capacity (except as otherwise expressly set
forth therein) but solely as owner trustee (the "Owner Trustee"), Allfirst Bank,
not in its individual capacity (except as otherwise expressly set forth therein)
but solely as Indenture Trustee, and Canadian Regional Aircraft Finance
Transaction No. 1 Limited, as loan participant (the "Loan Participant"); and
(ii) the Trust Indenture and Security Agreement [N583ML], dated as of August 10,
1999 (the "Indenture"), between the Owner Trustee and the Indenture Trustee.
Except as otherwise defined herein, capitalized terms used herein shall have the
meanings set forth in Appendix A to the Participation Agreement.

     As such counsel, we have examined executed counterparts or copies of the
Participation Agreement, the Indenture and the Equipment Note (collectively, the
"Indenture Trustee's Documents") and the other Operative Agreements to be
entered into by the parties in connection therewith, and such certificates of
public officials, such certificates of officers of the Indenture Trustee, and
originals or copies certified to our satisfaction of such corporate and other
documents, records and certificates of
<PAGE>

the Indenture Trustee and have considered such questions of law and fact, as we
have deemed relevant or necessary as a basis for the opinion, hereinafter set
forth.

     In such examination, we have assumed with your approval (a) the genuineness
of all signatures (other than that of the Indenture Trustee) on the Indenture
Trustee's Documents, the authenticity of all documents and instruments submitted
to us as originals, and the conformity to the originals of all documents and
instruments submitted to us as copies, which facts we have not independently
verified; (b) the due authorization, execution and delivery by each of the
parties to the Indenture Trustee's Documents (other than the Indenture Trustee)
and that each of such parties has the full power, authority and legal right to
execute, deliver and perform each such document; and (c) each of the Indenture
Trustee's Documents constitutes the legal, valid and binding agreement of the
parties thereto (other than the Indenture Trustee) and is enforceable against
each such party in accordance with the terms thereof.

     As to certain facts material to the opinions expressed herein, we have
relied solely upon the accuracy of the statements, representations and
warranties made by the parties in the Operative Agreements, and we have made no
independent investigation or inquiry with respect to such factual matters.

     In basing the opinions and other matters set forth herein on "our
knowledge", the words "our knowledge" signify that, in the course of our review
and analysis for the purpose of rendering this opinion, no information has come
to our attention that would give us actual knowledge or actual notice that any
such opinions or other matters are not accurate or that any of the foregoing
documents, records, certificates, statements and information on which we have
relied are not accurate and complete.  Except as otherwise stated herein, we
have undertaken no independent investigation or verification of such matters.
The words "our knowledge" and similar language used herein are further intended
to be limited to the knowledge of the lawyers within our firm who have worked on
matters relating to this opinion.

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

1.   Allfirst is a state-chartered commercial bank duly incorporated and
     presently existing under the laws of the State of Maryland and has the
     corporate power and authority to enter into and perform its obligations
     under the Indenture Trustee's Documents and the Indenture Trustee has the
     corporate power and authority to authenticate the Equipment Note to be
     delivered to the Loan Participant on the Delivery Date.

2.   Each of the Indenture Trustee's Documents has been duly authorized,
     executed and delivered by Allfirst or the Indenture Trustee (as the case
     may be) and each of the Indenture Trustee's Documents constitutes the
     legal, valid and binding obligation of the Indenture Trustee enforceable
     against the Indenture Trustee in accordance with its terms.
<PAGE>

3.   The Equipment Note to be issued and delivered to the Loan Participant on
     the Delivery Date has been duly authenticated and delivered by the
     Indenture Trustee pursuant to the terms of the Indenture.

4.   Neither the authorization, execution and delivery by Allfirst or the
     Indenture Trustee (as the case may be) of the Indenture Trustee's
     Documents, nor the authentication and delivery by the Indenture Trustee of
     the Equipment Note to be delivered to the Loan Participant on the Delivery
     Date nor the fulfillment or compliance by Allfirst or the Indenture Trustee
     (as the case may be) with the respective terms and provisions thereof nor
     the consummation of any of the transactions contemplated thereby, requires
     the consent or approval of, the giving of notice to, the registration with,
     or the taking of any other action in respect of, any court or
     administrative or governmental authority or agency of the State of Maryland
     or the United States of America governing the banking or trust powers of
     Allfirst.

5.   The execution, delivery and performance by Allfirst or the Indenture
     Trustee (as the case may be) of each of the Indenture Trustee's Documents
     and the authentication and delivery by the Indenture Trustee of the
     Equipment Note to be delivered to the Loan Participant on the Delivery Date
     do not and will not contravene the articles of incorporation or bylaws of
     Allfirst or, to our knowledge, of any existing law, governmental rule, or
     regulation or any judgment or order of the State of Maryland or the United
     States of America governing the banking or trust powers of Allfirst or, to
     our knowledge but without any independent investigation on our part, of any
     indenture, mortgage, contract or other instrument to which Allfirst or the
     Indenture Trustee (as the case may be) is a party or by which it or any of
     their respective properties may be bound.

6.   To our knowledge, there are no actions, suits, investigations or
     proceedings pending or threatened against or affecting Allfirst or the
     Indenture Trustee (as the case may be) or any of its properties in any
     court or before any administrative agency or arbitrator, which, if
     adversely determined, could materially adversely affect the ability of
     Allfirst or the Indenture Trustee (as the case may be) to perform its
     obligations under the Indenture Trustee's Documents, and to our knowledge,
     there are no actions or proceedings pending or threatened before any court,
     administrative agency or tribunal involving Allfirst or the Indenture
     Trustee (as the case may be) in connection with the transactions
     contemplated by any of the Indenture Trustee's Documents.

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

     A.   We are admitted to practice law in the State of Maryland and we do not
hold ourselves out as being experts on the laws of any other jurisdiction.
Accordingly, the foregoing opinions are expressly limited to matters under and
governed by the internal laws of the State of Maryland and applicable federal
laws of the United States of America governing the banking and trust powers of
Allfirst.  We express no opinion with respect to (i) ERISA, (ii) federal or
state (including the State of Maryland) laws, rules or regulations relating to
environmental matters or the offering of securities,
<PAGE>

including, without limitation, the Securities Act of 1933, as amended, the
Securities Exchange Act of 1934, as amended, and the Trust Indenture Act of
1939, as amended, or (iii) the aviation laws of the United States of America
including, without limitation, the Federal Aviation Act of 1958, as amended.

     B.   Insofar as the foregoing opinions relate to the validity and
enforceability in the State of Maryland of the Indenture Trustee's Documents
expressed to be governed by the laws of the State of New York, we have assumed
that the laws of the State of New York are identical to the laws of the State of
Maryland in all material respects, and the each of the Indenture Trustee's
Documents constitutes legal, valid, binding and enforceable documents or
instruments under such laws (as to which we express no opinion).

     C.   The foregoing opinions regarding the enforceability of the Indenture
Trustee's Documents against any of the parties thereto are subject to the
following:

          (i)   The enforceability of any of the Indenture Trustee's Documents
 may be limited or affected by (a) bankruptcy, insolvency, reorganization,
moratorium, liquidation, rearrangement, probate, conservatorship, fraudulent
transfers, fraudulent conveyances and other similar laws (including court
decisions) now or hereafter in effect and affecting the rights and remedies of
creditors generally or providing for the relief or debtors, (b) the refusal of a
particular court to grant (1) equitable remedies, including, without limiting
the generality of the foregoing, specific performance and injunctive relief, or
(2) a particular remedy sought by the Indenture Trustee under the Indenture as
opposed to another remedy provided for therein or another remedy available at
law or in equity, but which does not in our opinion make such remedies
inadequate for the practical realization of the benefits intended to be provided
thereby, and (c) general principles of equity (regardless or whether enforcement
is sought in a proceeding in equity or at law).

          (ii)  In rendering the foregoing opinions, we express no opinion as to
the enforceability of provisions of any of the Indenture Trustee's Documents (a)
purporting to waive or affect rights, claims, defenses or other benefits
bestowed by law, including, without limitation, the right to receive notices, to
the extent that any of the same cannot be waived or affected, or (b) relating to
indemnities to the extent prohibited by public policy or limited by federal or
state securities laws or which might require indemnification for losses or
expenses caused by gross negligence, willful misconduct, fraud or illegality of
an indemnified party, the rights of third parties, or the exercise of rights and
remedies with respect to the Aircraft other than in a commercially reasonable
manner or as otherwise provided in the Uniform Commercial Code or other
applicable law, or (c) imposing liquidated damages, late payment charges or
forfeitures if such amounts are determined to be penalties in light of the
actual amount of damages incurred.

          (iii) We note that the enforceability of specific provisions of
the Indenture Trustee's Documents may be subject to standards of reasonableness,
care and diligence and "good faith" limitations and obligations such as those
provided in Sections 1-102(3) and 1-203 of the Uniform Commercial Code and
similar applicable principles of common law and judicial decisions.
<PAGE>

          (iv) We express no opinion with respect to compliance with the anti-
fraud provisions of applicable federal or state securities rules or regulations.

     D.   Except to the extent expressly set forth in Paragraph 2, we have
assumed that each of the Indenture Trustee's Documents is enforceable against
each of the parties thereto.

     E.   We have assumed that the Participation Agreement and the transactions
contemplated thereby are not within the prohibitions of Section 406 of the
Employee Retirement Income Security Act of 1974, as amended.

     F.   We do not purport to be experts in respect of, and express no opinion
concerning any of the laws, rules or regulations applicable to, the particular
nature of the Aircraft and other equipment involved in this transaction.

     G.   We have made no investigation of, and we express no opinion
concerning, the ownership of, or legal or equitable title to, the Aircraft and
other equipment or property involved in this transaction or the creation,
perfection or priority of any security interest granted pursuant to any of the
Operative Agreements.

     H.   We express no opinion as to the availability of the benefits of
Section 1110 of the Bankruptcy Code to the Aircraft, any Replacement Aircraft or
Replacement Engine.

     I.   The opinions expressed herein concern only the effect of the laws
(excluding the principles of conflict of laws) of the State of Maryland and the
United States of America as currently in effect.  We assume no obligation to
supplement this opinion if any applicable laws change after the date hereof or
if we become aware of any fact that might change the opinions expressed herein
after the date hereof.

     J.   The opinions expressed in this letter are limited to the matters set
forth in this letter, and no other opinions should be inferred beyond the
matters expressly stated.

     This opinion is being delivered pursuant to Section 3.01(b)(xix)(D) of the

Re:  One Bombardier Inc. CL-600-2BI9 Aircraft Bearing U.S. Registration No.
     N583ML and leased to Midway Airlines Corporation

Ladies and Gentlemen:

          We have acted as counsel to First Union Trust Company, National
Association (the "Trust Company"), in connection with the Trust Agreement, dated
as of August 10, 1999, (the "Trust Agreement"), by and between the Trust Company
and Polaris Holding Company, as Owner Participant (the "Owner Participant").
Pursuant to the Participation Agreement, dated as of August 10, 1999 (the
"Participation Agreement"), by and among Midway Airlines Corporation, as Lessee
(the "Lessee"), the Owner Participant, Allfirst Bank, as Indenture Trustee,
Canadian Regional Aircraft Finance Transaction No. 1 Limited, as Loan
Participant, and the Trust Company, not in its individual capacity, except as
specifically set forth therein, but solely as Owner Trustee under the Trust
Agreement (the "Owner Trustee"), financing is being provided in connection with
one Bombardier Inc. CL-600-2B19 aircraft bearing U.S. Registration No. N583ML
(the "Aircraft"). This opinion is furnished upon the request of the Owner
Trustee pursuant to Section 3.01(b)(xix)(C) of the Participation Agreement.
Capitalized terms used herein and not otherwise defined are used as defined in
or by reference in the Participation Agreement, except that reference herein to
any instrument shall mean such instrument as in effect on the date hereof.

          We have examined forms, counterparts or copies otherwise identified to
our satisfaction of the following documents:

          (a)  the Participation Agreement;

          (b)  the Trust Agreement;

          (c)  the Lease Agreement and Lease Supplement No. 1;
<PAGE>

          (d)  the Trust Indenture and Security Agreement and Indenture
               Supplement No. 1;

          (e)  the Deficiency Agreement;

          (f)  the Equipment Note being issued today (the "Equipment Note");

          (g)  the Engine Warranty Assignment; and

          (h)  the Purchase Agreement Assignment.

          The documents identified in paragraphs (a) through (h) above are
collectively referred to herein as the "Owner Trustee Agreements".

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

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

          1.   The Trust Company is a national banking association, duly
organized and validly existing in good standing under the laws of the United
States, is a Citizen of the United States, and has the corporate, banking and
trust powers to enter into and perform its obligations under the Trust Agreement
and the Participation Agreement, and the Owner Trustee has the authority under
the Trust Agreement to execute, deliver and perform its obligations under the
Owner Trustee Agreements and to issue, execute, deliver and perform the
Equipment Note.

          2.   The Trust Agreement and each other Owner Trustee Agreement have
been duly authorized, executed and delivered by the Trust Company or by the
Owner Trustee, as the case may be, and are the legal, valid and binding
obligations of the Trust Company or the Owner Trustee, as the case may be,
enforceable against the Trust Company or the Owner Trustee, as the case may be,
in accordance with their respective terms; and the Trust Agreement is the legal,
valid and binding obligation of the Owner Participant, enforceable against the
Owner Participant in accordance with its terms.

          3.   The Equipment Note has been duly authorized, issued, executed and
delivered by the Owner Trustee, pursuant to authorization contained in the Trust
Agreement, and constitutes a legal, valid and binding obligation of the Owner
Trustee, enforceable against the Owner Trustee in accordance with its terms and
the terms of the Trust Indenture; and the Equipment Note is entitled to the
benefits and security afforded by the Trust Indenture in accordance with its
terms and the terms of the Trust Indenture.
<PAGE>

          4.   Neither the execution and delivery by the Trust Company or the
Owner Trustee, as the case may be, of the Owner Trustee Agreements, nor the
issuance, execution and delivery by the Owner Trustee of the Equipment Note, nor
the fulfillment of or compliance by the Trust Company or the Owner Trustee, as
the case may be, with the respective provisions thereof, conflicts with, or
results in a breach of the terms, conditions or provisions of, or constitutes a
default under, or results in a violation of, the charter or by-laws of the Trust
Company, any law, governmental rule or regulation of the State of Delaware or
any federal law, governmental rule or regulation of the United States of America
governing the banking or trust powers of the Trust Company or, to the best of
our knowledge, any agreement, indenture, mortgage, bank credit agreement, note
or bond purchase agreement, instrument, order, judgment or decree to which the
Trust Company, the Owner Trustee or any of their respective properties is
subject.

          5.   No consent, approval or other action by or any notice to or
filing with any court or administrative or governmental body is required under
the laws of the State of Delaware or the federal laws of United States of
America governing the banking or trust powers of the Trust Company in connection
with the authorization, execution and delivery by the Trust Company or the Owner
Trustee of the Owner Trustee Agreements, the authorization, issuance, execution
and delivery by the Owner Trustee of the Equipment Note, or the fulfillment of
or compliance by the Trust Company or the Owner Trustee with the respective
terms and provisions thereof.

          6.   The Trust Agreement creates for the benefit of the Owner
Participant the rights and interests in the Trust Estate which the Trust
Agreement by its terms purports to create.

          7.   There is no fee, tax or other governmental charge under the laws
of the State of Delaware or any political subdivision thereof in existence on
the date hereof on, based on or measured by any payments under the Lease or the
beneficial interests in the Trust Estate, by reason of the creation of the trust
under the Trust Agreement pursuant to the laws of the State of Delaware or the
Owner Trustee's performance of its duties under the Trust Agreement within the
State of Delaware, which would not have been imposed if the Trust Company did
not have its principal place of business and did not perform its obligations
under the Owner Trustee Agreements in the State of Delaware.

          8.   Assuming that (i) the Aircraft is not used in the State of
Delaware and is not physically located in the State of Delaware at the
commencement or termination of the Term or during such Term, (ii) in connection
with any sale of the Aircraft, such Aircraft will not be physically delivered in
the State of Delaware to a buyer nor be shipped from a point within the State of
Delaware to a buyer, and (iii) the trust created by the Trust Agreement is
treated as a grantor trust for federal income tax purposes within the
contemplation of Sections 671 through 678 of the Internal Revenue Code of 1986,
as amended, there are no fees, taxes, or other charges (except taxes imposed on
fees payable to the Owner Trustee) payable to the State of Delaware or any
political subdivision thereof in connection with the execution, delivery or
performance by the Owner Trustee, the Indenture Trustee, the Loan Participant,
the Lessee or the Owner Participant, as the case may be, of the Owner Trustee
Agreements or in connection with the making by the Owner Participant of its
acquisition of the beneficial interest in the Trust Estate or in connection with
the issuance and acquisition of the Equipment Note, and neither the Owner
Trustee, the Trust Estate nor the trust created by the Trust Agreement will be
subject to any fee, tax or other governmental charge (except taxes on fees
payable to the Owner Trustee) under
<PAGE>

the laws of the State of Delaware or any political subdivision thereof on, based
on or measured by, directly or indirectly, the gross receipts, net income or
value of the Trust Estate solely by reason of the creation or continued
existence of the trust under the terms of the Trust Agreement pursuant to the
laws of the State of Delaware or the Owner Trustee's performance of its duties
under the Trust Agreement.

          9.   To the best of our knowledge, there are no proceedings pending or
threatened against or affecting the Trust Company or the Owner Trustee in any
court or before any governmental authority, agency or arbitration board or
tribunal which, if adversely determined, individually or in the aggregate, would
materially and adversely affect the right, power and authority of the Trust
Company or the Owner Trustee to enter into or perform its obligations under the
Owner Trustee Agreements and the Equipment Note.

          10.  Neither a Delaware court nor a Federal court applying federal or
Delaware law, if properly presented with the issue and after having properly
considered such issue, would permit the Owner Participant to terminate the Trust
Agreement, except in accordance with its terms.

          11.  Creditors of any person that is an Owner Participant, holders of
a lien against the assets of any such person and representatives of creditors of
any such person, such as trustees, receivers or liquidators (whether or not any
insolvency proceeding has been commenced) (collectively, the "Creditors") may
acquire valid claims and liens, as to the Trust Estate, only against the rights
of such Owner Participant under the Trust Agreement or in the Trust Estate, and
do not have, and may not through the enforcement of such Creditors' rights
acquire, any greater rights than such Owner Participant with respect to the
Trust Agreement or the Trust Estate.

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

          A.   The foregoing opinions are limited to the laws of the State of
Delaware and the federal laws of the United States of America governing the
banking and trust powers of the Trust Company, except that the opinion rendered
in paragraph 10 above is limited to the laws of the State of Delaware and Title
11 of the United States Code entitled "Bankruptcy" and the opinion rendered in
paragraph 11 above is limited to the laws of the State of Delaware. In addition,
we express no opinion with respect to (i) federal securities laws, including the
Securities Act of 1933, as amended, and the Trust Indenture Act of 1939, as
amended, (ii) the Federal Aviation Act of 1958, as amended (except with respect
to the opinion set forth in paragraph 1 above concerning the citizenship of the
Trust Company), (iii) the Federal Communications Act of 1934, as amended, or
(iv) state securities or blue sky laws. Insofar as the foregoing opinions relate
to the validity and enforceability of the Equipment Note and the Owner Trustee
Agreements expressed to be governed by laws other than the laws of the State of
Delaware, we have assumed that the Equipment Note and such Owner Trustee
Agreements constitute legal, valid, binding and enforceable documents or
instruments under such laws (as to which we express no opinion).

          B.   The foregoing opinions regarding enforceability of any document
are subject to (i) applicable bankruptcy, insolvency, moratorium,
reorganization, fraudulent transfer, receivership and similar laws affecting the
rights and remedies of creditors generally, and (ii) general principles of
equity
<PAGE>

(regardless of whether such enforceability is considered in a proceeding
in equity or at law).  For the avoidance of doubt, the opinions rendered in
paragraphs 10 and 11 above are not subject to the qualifications set forth in
this paragraph B, except to the extent expressly stated in paragraph I hereof.

          C.   We have assumed the due authorization, execution and delivery by
each of the parties thereto, other than the Trust Company and the Owner Trustee,
of the Owner Trustee Agreements to which each is a party and that each of such
parties has the full power, authority and legal right to execute and deliver
each such document.

          D.   The opinion set forth in paragraph 1 above concerning the
citizenship of the Trust Company is based upon an affidavit of an officer of the
Trust Company, the facts set forth in which we have not independently verified.

          E.   We have assumed that all signatures, other than those of the
Trust Company or the Owner Trustee, on documents and instruments submitted to us
as originals are authentic, and that all documents and instruments submitted to
us as copies conform with the originals, which facts we have not independently
verified.

          F.   We do not purport to be experts in respect of, or express any
opinion concerning, aviation law or other laws, rules or regulations applicable
to the particular nature of the equipment to be acquired by the Owner Trustee.

          G.   We have assumed that the Owner Trustee Agreements and the
transactions contemplated thereby are not within the prohibitions of Section 406
of the Employee Retirement Income Security Act of 1974.

          H.   No opinion is expressed as to the nature of the title to any part
of the Trust Estate or the priority of any mortgage or security interest.

          I.   The opinions set forth in paragraphs 10 and 11 above are subject
to (i) fraudulent transfer laws and avoidance actions (e.g. preference laws),
and (ii) general principles of equity, including, without limitation,
substantive consolidation (regardless of whether considered in a proceeding in
equity or at law) and should be interpreted in accordance with the Special
Report by the TriBar Opinion Committee, Opinions in the Bankruptcy Context:

     Re:  Bombardier Inc. model CL-600-2B19 aircraft with manufacturer's
          serial number 7327 and United States nationality and
          registration marks N583ML (the "Aircraft")
          --------------------------------------------------------------

Ladies and Gentlemen:

     This letter confirms that we filed the following described instruments with
the Federal Aviation Administration (the "FAA") today at the respective times
noted below:

     (a) AC Form 8050-2 Aircraft Bill of Sale dated August __, 1999 (the "FAA
Bill of Sale") by Bombardier Capital Inc. to First Union Trust Company, National
Association, as Owner Trustee (the "Owner Trustee") under Trust Agreement
[N583ML] dated as of August __, 1999 (the "Trust Agreement") between Polaris
Holding Company as Owner Participant and the Owner Trustee, covering the
Aircraft was filed at __:__ _.M., C. D. T.;

     (b) AC Form 8050-1 Aircraft Registration Application by the Owner Trustee
covering the Aircraft, to which were attached the Affidavits required by Section
47.7(c)(2)(ii) of Part 47 of the Federal Aviation Regulations, was filed at:
__:__ _.M., C.D.T.;

     (c) the Trust Agreement was filed at __:__ _.M., C.D.T.;

     (d) Trust Indenture and Security Agreement [N583ML] dated as of August __,
1999 (the "Indenture") between the Owner Trustee and Allfirst Bank as Indenture
Trustee (the "Indenture Trustee"), to which was attached Indenture Supplement
No. 1 [N583ML] dated August __, 1999 (the "Indenture Supplement") covering the
Aircraft and the General Electric model CF34-3B1 aircraft engines with
manufacturer's serial numbers GE-E-872529 and GE-E-872530 (the "Engines"), was
filed at __:__ _.M., C.D.T.; and

     (e) Lease Agreement [N583ML] dated as of August __, 1999 (the "Lease")
between the Owner Trustee as lessor and Midway Airlines Corporation (the
"Lessee"), to which were attached Lease Supplement No. 1 [N583ML] dated August
__, 1999 (the "Lease Supplement") covering the Aircraft and the Engines, the
Indenture and the Indenture Supplement, was filed at __:__ _.M., C.D.T.
<PAGE>

     Based upon our examination of the above described instruments and of such
records of the FAA as we deemed necessary to render this opinion and as were
made available to us by the FAA, it is our opinion that:

          a.   the FAA Bill of Sale, the Indenture with the Indenture Supplement
attached and the Lease with the Lease Supplement, attached are in due form for
recordation by and have been duly filed for recordation with the FAA pursuant to
and in accordance with the provisions of Section 44107 of Title 49 of the United
States Code;

          b.   legal title to the Aircraft is vested in the Owner Trustee and
all instruments necessary to cause the FAA in due course to issue to the Owner
Trustee an AC Form 8050-3 Certificate of Aircraft Registration covering the
Aircraft have been duly filed with the FAA pursuant to and in accordance with
the provisions of Sections 44102 and 44103 of Title 49 of the United States
Code;

          c.   the Aircraft and the Engines are free and clear of Liens (as such
term is defined in the Lease) other than such as are created by the Indenture,
as supplemented by the Indenture Supplement, and by the Lease, as supplemented
by the Lease Supplement;

          d.   the Indenture, as supplemented by the Indenture Supplement,
creates a duly and validly perfected first priority security interest in favor
of the Indenture Trustee in the Aircraft and the Engines and in all of the
right, title and interest of the Owner Trustee in and to the Lease, as
supplemented by the Lease Supplement (insofar as such security interest affects
an interest covered by the recording system established by the FAA pursuant to
Section 44107 of Title 49 of the United States Code);

          e.   the rights of the Owner Trustee and the Lessee under the Lease,
as supplemented by the Lease Supplement, with respect to the Aircraft and the
Engines are perfected;

          f.   none of the Indenture, the Indenture Supplement, the Lease or the
Lease Supplement is required under the applicable laws of any jurisdiction
within the United States to be refiled with the FAA or filed or recorded in any
other place within the United States in order to perfect or maintain the
perfection of (i) the security interest in the Aircraft and the Engines and (ii)
the assignment for security purposes of the Lease (insofar as such assignment
affects an interest covered by the recording system established by the FAA
pursuant to Section 44107 of Title 49 of the United States Code), all as created
by the Indenture, as supplemented by the Indenture Supplement;

          g.   no other registration of the Aircraft and no filings or
recordings (other than the filings and recordings with the FAA Aircraft Registry
which have been effected) are necessary to perfect in any jurisdiction within
the United States the Owner Trustee's title to the Aircraft or the security
interest created by the Indenture, as supplemented by the Indenture Supplement,
in the Aircraft and the Engines under the applicable laws of any jurisdiction
within the United States; and

          h.   no authorization, approval, consent, license or order of, or
registration with, or the giving of notice to the FAA Aircraft Registry is
required for the valid authorization, delivery and
<PAGE>

performance of the Indenture or the Indenture Supplement, except for such
filings as are referred to above.

     No opinion is herein expressed as to: (i) laws other than the federal laws
of the United States; (ii) the validity or enforceability under local law of the
Indenture, as supplemented by the Indenture Supplement; (iii) the recognition of
the perfection of the security interest created by the Indenture, as
supplemented by the Indenture Supplement, against third parties in any legal
proceedings outside the United States; and (iv) the record status of the
Aircraft prior to the commencement of its United States registration.  Since our
examination was limited to records maintained by the FAA Aircraft Registry, our
opinion does not cover liens which are perfected without the filing of notice
thereof with the FAA, such as federal tax liens, liens arising under Section
1368(a) of Title 29 of the United States Code and possessory artisans' liens,
and was subject to the accuracy of FAA personnel in the filing, indexing and
recording of instruments filed with the FAA and in the search for encumbrance
cross-reference index cards for the Engines.  This opinion is rendered in
reliance upon the opinion of the Aeronautical Center Counsel dated August 9,
1999 (a copy of which is attached hereto) and upon the past practice of the FAA
which is consistent with said opinion.

                                    Very truly yours,

          Re:  Participation Agreement [N _____ ML]
               ------------------------------------

Ladies and Gentlemen:

          We have acted as special counsel for Polaris Holding Company, a
Delaware corporation (the "Owner Participant"), in connection with the
transactions contemplated by the Participation Agreement [N____ML], dated as of
________________ (the "Participation Agreement"), among (a) Midway Airlines
Corporation, as Lessee (the "Lessee"), (b) the Owner Participant, (c) First
Union Trust Company, National Association, as Owner Trustee (the "Owner
Trustee"), (d) Canadian Regional Aircraft Finance Transaction No. 1 Limited, as
Loan Participant, and (e) Allfirst Bank, as Indenture Trustee.  This opinion is
delivered pursuant to Section 3.01(b)(xix)(I) of the Participation Agreement.
Unless otherwise defined herein, all capitalized terms used herein shall have
the respective meanings set forth or referred to in Appendix A to the
Participation Agreement.

          In connection with our opinions expressed herein, we have examined
executed counterparts of the Participation Agreement, the Trust Agreement and
the Tax Indemnity Agreement (collectively, the "Owner Participant Agreements").
We have further examined and relied upon the accuracy of original, certified,
conformed, photographic or telecopied copies of such records, agreements,
certificates and other documents as we have deemed necessary or appropriate to
enable us to render the opinions expressed herein.  In all such examinations, we
have assumed the genuineness of signatures on original documents and the
conformity to such original documents of all copies submitted to us as
certified, conformed, photographic or telecopied copies, and as to certificates
and telegraphic and telephonic confirmations given by public officials, we have
assumed the same to have been properly given and to be accurate.  As to all
matters of fact material to our opinions, we have relied upon the accuracy of
the statements, representations and warranties made in the Owner Participant
Agreements and certificates furnished to us, and we have made no independent
investigation or verification with respect to such factual matters.

          We have assumed (without making any independent investigation or
verification with respect thereto) the due authorization, execution and delivery
of the Operative Agreements by each of the parties thereto and that each
Operative Agreement constitutes the legal, valid and binding obligation of each
of such parties (other than the Owner Participant), enforceable against each
such party (other than the Owner Participant) in accordance with its terms, that
each such party has or had, at the time
<PAGE>

of its execution thereof, the requisite power, authority and legal right to
execute, deliver and perform each Operative Agreement to which it is a party,
that the execution, delivery and performance thereof by each such party do not
violate its respective partnership agreement, or charter or by-laws, and that
the execution, delivery and performance thereof by each such party do not
violate any laws or governmental rules or regulations (federal, state or
otherwise) that may be applicable to it, in any capacity in which it may be
acting, and that the transactions provided for in the Operative Agreements are
not within the prohibition of Section 406 of the Employee Retirement Income
Security Act of 1974, as amended.

          Based upon and subject to the foregoing and the matters hereinafter
set forth, we are of the opinion that each Owner Participant Agreement
constitutes a legal, valid and binding obligation of the Owner Participant
enforceable against it in accordance with its terms, except as limited by (a)
applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting the rights and remedies of creditors generally, (b) public policy
considerations (in the case of the indemnity provisions contained therein), and
(c) general principles of equity (regardless of whether considered in a
proceeding in equity or at law).

          We express no opinions herein as to the laws of any state or
jurisdiction other than the laws of the State of New York and the federal laws
of the United States of America.  We note that the Trust Agreement is governed
by the laws of the State of Delaware.  Insofar as the foregoing opinions relate
to the legality, validity, binding effect and enforceability of the Trust
Agreement, we have assumed for purposes of such opinions (notwithstanding the
express provisions of the Trust Agreement to the contrary) that the Trust
Agreement is governed by the laws of the State of New York and we express no
opinion as to the enforceability of the choice of law provisions in the Trust
Agreement.  We express no opinion herein as to (i) any state or federal
securities or tax laws, (ii) the perfection or priority of any security interest
created by any of the Operative Agreements or as to the right, title or interest
in or to the Lessor's Estate or the Indenture Estate on the part of any Person
or (iii) matters governed by Title 49 of the United States Code or by any other
aviation law or law, statute, rule or regulation of the United States of America
relating to the acquisition, ownership, leasing, registration, use, operation,
maintenance, repair, replacement, sale of or the particular nature of the
Aircraft, Airframe or Engines.

          Insofar as our opinions expressed herein related to the Tax Indemnity
Agreement, such opinions are being rendered solely to the Lessee.

          In rendering the foregoing opinions, we have relied, without making
any independent investigation with respect thereto, upon the opinion of Jeanette
Pinard, acting as internal counsel for Polaris Holding Company, delivered to you
on the date hereof, as to the matters addressed therein.

          This opinion is furnished by us for your sole benefit and we agree
that you may rely on the opinions expressed herein.  No other Person shall be
entitled to rely on the opinions expressed herein without our express written
consent.  This opinion is limited to the matters stated herein and no opinion is
implied or may be inferred beyond the matters expressly stated herein.

          Re:  Participation Agreement [N__ML]
               -------------------------------

Ladies and Gentlemen:

          I have acted as internal counsel for Polaris Holding Company, a
Delaware corporation (the "Owner Participant") in connection with the
transactions contemplated by the Participation Agreement [N___ML], dated as of
_______________________ (the "Participation Agreement"), among (a) Midway
Airlines Corporation, as Lessee, (b) the Owner Participant, (c) First Union
Trust Company, National Association, as Owner Trustee, (d) Canadian Regional
Aircraft Finance Transaction No. 1 Limited, as Loan Participant, and (e)
Allfirst Bank, as Indenture Trustee.  This opinion letter is given pursuant to
Section 3.01(b)(xix)(I) of the Participation Agreement.  For purposes of this
opinion letter, all capitalized terms used but not defined herein are used as
defined in Appendix A to the Participation Agreement.

          In connection with the opinions contained herein, I have examined
executed counterparts of the Participation Agreement, the Trust Agreement and
the Tax Indemnity Agreement (collectively, the "Owner Participant Agreements").
I have further examined and relied upon the accuracy of original, certified,
conformed, photocopied or telecopied copies of such records, agreements,
certificates and other documents as I have deemed necessary or appropriate to
enable me to render the opinions expressed herein.  In all such examinations, I
have assumed the genuineness of signatures on original documents (other than
signatures of the Owner Participant) and the conformity to such original
documents of all copies submitted to me as certified, conformed, photocopied or
telecopied copies, and as to certificates and telegraphic and telephonic
confirmations given by public officials, I have assumed the same to have been
properly given and to be accurate.  As to various questions of fact material to
my opinions, I have relied, when relevant facts were not independently
established by me, solely upon the accuracy of the statements, representations
and warranties made in the Owner Participant Agreements and in any certificate
furnished to me.

          Based upon the foregoing, and subject to the specific assumptions,
qualifications and reliances herein set forth, and on the basis of my
consideration of such facts and laws as I have deemed necessary for purposes of
this opinion letter, it is my opinion that:
<PAGE>

1.   The Owner Participant is a corporation duly organized, validly existing and
     in good standing under the laws of the State of Delaware, and has the
     corporate power and authority to execute and deliver and to perform its
     obligations under the Owner Participant Agreements.

2.   Each of the Owner Participant Agreements has been duly authorized, executed
     and delivered by the Owner Participant.

3.   Neither the execution and delivery by the Owner Participant of the Owner
     Participant Agreements nor the performance by the Owner Participant of its
     obligations under the Owner Participant Agreements, (i) requires for its
     validity the consent or approval of, the giving of notice to, the
     registration with, or the taking of any other action with respect to, any
     governmental authority or agency of the United States of America or the
     State of New York, other than Federal Aviation Administration filings as to
     which I express no opinion; (ii) contravenes any law or governmental rule
     or regulation of the United States of America or the State of New York, or,
     to the best of my knowledge, any judgment or order applicable to or binding
     on the Owner Participant; or (iii) contravenes, results in any breach of or
     constitutes any default under, any provision of the Owner Participant's
     certificate of incorporation or its by-laws or, to the best of my
     knowledge, any agreement or instrument to which the Owner Participant is a
     party or by which it is bound.

4.   To my knowledge, after reasonable inquiry, there are no pending or overtly
     threatened actions or proceedings before any court or administrative agency
     or arbitrator which, if adversely determined, would materially and
     adversely affect the Owner Participant's ability to perform its obligations
     under any of the Owner Participant Agreements.

          I am qualified to practice law in the State of New York and I express
no opinion as to the laws of any jurisdiction other than laws of the State of
New York, the General Corporation Law of the State of Delaware and the federal
laws of the United States of America.  I express no opinion herein as to (i) any
federal or state securities or tax laws or (ii) aviation law or other laws,
statutes, rules or regulations applicable to the registration, use, operation,
maintenance, repair or replacement of or the nature of the Aircraft.  Further,
no opinion is expressed as to title to the Aircraft or any part thereof.

          Insofar as my opinions relate to the Tax Indemnity Agreement, such
opinions are being rendered solely to the Lessee.

          I understand and agree that you may rely upon this opinion letter in
connection with the transactions described in the Owner Participant Agreements,
but no other person or entity shall be entitled to rely on the opinions
contained herein without my express written consent.  My opinions are limited to
the matters stated herein, and no opinion is implied or may be inferred beyond
the matters expressly stated herein.

          Dewey Ballantine LLP, as special counsel to Polaris Holding Company,
may rely on the opinions expressed in this letter in rendering their opinions
pursuant to Section 3.01(b)(xix)(I) of the Participation Agreement.

                                    Very truly yours,

Agreement are within Guarantor's power and authority, have been duly authorized
by all necessary corporate action on the part of Guarantor and do not contravene
<PAGE>

the charter or the by-laws of Guarantor or any indenture, mortgage, credit
agreement, note, long-term lease or other material agreement to which Guarantor
is a party or by which Guarantor is bound, and this Guaranty Agreement
constitutes a legal, valid and binding obligation of Guarantor, enforceable
against Guarantor in accordance with its terms.

  3.     Submission to Jurisdiction, Etc. Guarantor hereby agrees to be bound,
         -------------------------------
to the same extent Owner Participant is bound, by the provisions of Section
15.08 of the Participation Agreement, which are incorporated herein by reference
as if fully set forth herein.

  4.     Undertaking.  Guarantor hereby unconditionally and irrevocably
         -----------
guaranties not merely as surety but as primary obligor, the due and punctual:
(i) performance by Assignee of all of the obligations of the "Owner Participant"
under the Operative Agreements assumed by Assignee under the Assignment
Agreement; (ii) payment of any and all sums which are payable by the Owner
Participant pursuant to any of the Operative Agreements which payment
obligations were assumed by Assignee under the Assignment Agreement; and (iii)
performance of, observance of and compliance with all other obligations,
covenants and undertakings and representations and warranties of, or made by,
Assignee in the Assignment Agreement or the Owner Participant contained in or
arising under the Operative Agreements and assumed by Assignee under the
Assignment Agreement (such payments and other obligations referred to in this
Section 4(a) hereinafter referred to as the "Obligations").  Guarantor agrees
                                             -----------
that it will not use the assets of any ERISA Plan to fund its payment
obligations hereunder.

  (a)    Guarantor agrees that this Guaranty Agreement is an unconditional
and absolute guaranty of payment and performance (not merely collectability),
that its undertakings hereunder are not contingent upon any Guaranteed Party
bringing any action against Assignee or resorting to any security and hereby
expressly waives any claim that its undertakings hereunder are so contingent.

  (b)    Guarantor irrevocably waives promptness, diligence, demand, and all
notices whatsoever as to the Obligations guaranteed hereby, and any other
circumstances which might otherwise constitute a defense available to it, or a
discharge of it (other than the defense of payment or performance), and agrees
that it shall not be required to consent to or receive any notice of any
amendment or modification of, or waiver, consent or extension with respect to,
the Participation Agreement or the other Operative Agreements to which Assignee
is a party that may be made or given as provided herein or otherwise.

  (c)    Guarantor further agrees to pay all expenses (including, without
limitation, all fees and disbursements of counsel) that may be paid or incurred
by any Guaranteed Party in enforcing any rights with respect to, or collecting,
any or all of the Obligations and/or enforcing any rights with respect to, or
collecting against, the Guarantor under this Guaranty Agreement.

  (d)    Guarantor understands and agrees that its obligations hereunder shall
be construed as continuing, absolute and unconditional without regard to (i) the
validity, regularity or enforceability of any Operative Agreement, any of the
Obligations or any collateral security therefor or guarantee or right of offset
with respect thereto at any time or from time to time held by any Guaranteed
Party, (ii)
<PAGE>

any defense, set-off or counterclaim (other than a defense of payment or
performance) that may at any time be available to or be asserted by Assignee
against any Guaranteed Party, or (iii) any other circumstances whatsoever (with
or without notice to or knowledge of Assignee or the Guarantor) that
constitutes, or might be construed to constitute, an equitable or legal
discharge of Assignee for the Obligations, or of Guarantor under this Guaranty
Agreement, in bankruptcy or in any other instance.

  5.     No Discharge.  The obligation of Guarantor hereunder will not be
         ------------
discharged by: (a) any extension or renewal with respect to any obligation of
Assignee, as Owner Participant, under the Operative Agreements; (b) any
modification of, or amendment or supplement to, any such agreement; (c) any
furnishing or acceptance of additional security or any release of any security;
(d) any waiver, consent or other action or inaction or any exercise or non-
exercise of any right, remedy or power with respect to Assignee, or any change
in the structure of Assignee; (e) any insolvency, bankruptcy, reorganization,
arrangement, composition, liquidation, dissolution or similar proceedings with
respect to Assignee; (f) except as provided in Section 6 any change in ownership
of the shares of capital stock of Guarantor or Assignee; or (g) any other
occurrence whatsoever, except payment in full of all amounts payable by
Assignee, as Owner Participant, under the Operative Agreements and performance
in full of all Obligations of Assignee, as Owner Participant, in accordance with
the terms and conditions of the Operative Agreements.

  6.     Transfers.  Guarantor may assign, convey or otherwise transfer its
         ---------
obligations hereunder to any other Person (hereinafter referred to as the
"Transferee Guarantor"), provided that (i) the Transferee Guarantor enters into
 --------------------
an agreement substantially in the form of this Guaranty Agreement and (ii) the
Transferee Guarantor meets the requirements of Section 5.01(c) of the
Participation Agreement relating to a "guarantor".  If pursuant to Section
5.01(c) of the Participation Agreement or the preceding sentence, a new guaranty
shall be delivered or the obligations of the Guarantor shall be transferred, the
Transferee Guarantor shall deliver an opinion or opinions of counsel
substantively similar to the form of opinion attached to the Participation
Agreement as Exhibit B-3 to the effect that the obligations incurred by the
Transferee Guarantor pursuant hereto constitute the legal, valid, binding and
enforceable obligations of such Transferee Guarantor.  Upon the satisfaction by
the Guarantor of the conditions set forth in this Section 6, the Guarantor shall
be released and discharged of any and all further obligations under this
Guaranty Agreement.

  7.     Reinstatement.  Guarantor agrees that this Guaranty Agreement shall be
         -------------
automatically reinstated with respect to any payment made prior to the
termination of this Guaranty Agreement by or on behalf of Assignee pursuant to
the Participation Agreement or the other Operative Agreements to which Assignee
is a party if and to the extent that such payment is rescinded or must be
otherwise restored, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise.

  8.     No Subrogation.  Notwithstanding any payment or payments made by
         --------------
Guarantor hereunder or any set-off or application of funds of Guarantor by any
Guaranteed Party, Guarantor shall not be entitled to be subrogated to any of the
rights of any Guaranteed Party against Assignee or any collateral, security or
guarantee or right of set-off held by any Guaranteed Party for the payment of
the Obligations, nor shall Guarantor seek or be entitled to seek any
reimbursement from Assignee in respect of payments made by Guarantor hereunder,
until all amounts and performance owning to the Guaranteed Parties by Assignee
on account of the Obligations are paid and performed in full.
<PAGE>

  9.     Severability.  Any provision of this Guaranty Agreement that is
         ------------
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

  10.    Miscellaneous.  This Guaranty Agreement shall: (a) be binding upon
         -------------
Guarantor, its successors and assigns; (b) inure to the benefit of, and be
enforceable by, the Guaranteed Parties but shall not, and is not intended to,
create rights in any other third parties; (c) not be waived, amended or modified
without the written consent of each of the Guaranteed Parties; (d) be governed

Agreement and the Operative Agreements and by Guarantor hereunder, and
performance in full of all other Obligations of Assignee, as Owner Participant,
under the Assignment Agreement and the Operative Agreements and (ii) the
compliance by Guarantor with Section 6.  All notices to, requests of, demands on

  Re:    Midway Airlines Corporation - One Canadian Regional Jet
         -------------------------------------------------------
         Series 200ER Aircraft Bearing Registration No. N____ML
         ------------------------------------------------------


Ladies and Gentlemen:

         As counsel to ____________, a ______________ ("Assignee"), I advise you
                                                        --------
as follows in connection with the Assignment and Assumption Agreement dated as
of _________ __, ____ (the "Assignment Agreement") between Assignee and
                            --------------------
_______________, a ____________ ("Assignor"), and the transactions contemplated
                                  --------
thereby.  Capitalized terms used herein and not defined herein shall have the
respective meanings attributed thereto in the Assignment Agreement.  This
opinion is being furnished to you pursuant to the request of Assignee and
Section 5.01(c)(v) of the Participation Agreement.

         I have, or an attorney under my supervision has, examined the
Assignment Agreement. I have, or an attorney under my supervision has, also
examined the originals, or certified, conformed, photocopied or telecopied
copies of such corporate records, certificates, instruments and other documents
as I have deemed necessary or appropriate to enable me to render the opinions
expressed herein.  In all such examinations, I have assumed the genuineness of
signatures on original documents (other than those of Assignee) and the
conformity to such original documents of all copies submitted to me as
certified, conformed, photocopied or telecopied copies, and as to certificates
and telegraphic and telephonic confirmations given by public officials, I have
assumed the same to have been properly given and to be accurate.  As to all
matters of fact material to my opinions, I have, when relevant facts were not
independently established, relied upon statements, representations and
warranties contained in the Assignment Agreement and upon the statements and
certificates furnished to me.

         In addition, in rendering the opinions expressed herein I have assumed
that (i) the Assignment Agreement has been duly authorized, executed and
delivered by Assignor and constitutes the legal, valid and binding obligation of
Assignor, enforceable against Assignor in accordance with its terms, (ii)
Assignor has the requisite power, authority and legal right to enter into and
perform its respective obligations under the Assignment Agreement and (iii) the
transactions provided for in the Assignment Agreement are not within the
prohibitions of Section 406 of the Employee Retirement Income Security Act of
1974, as amended or Section 4975 of the Internal Revenue Code of 1986, as
amended.
<PAGE>

  A.     Based upon the foregoing and subject to the limitations expressed in
paragraph B below, I am of the opinion that:

         1. Assignee is a __________ duly organized, validly existing and in
  good standing under the laws of [ ] and has full corporate power and authority
  to execute, deliver and perform the Assignment Agreement.

         2. The Assignment Agreement has been duly authorized, executed and
  delivered by Assignee.

         3. Neither the execution and delivery of the Assignment Agreement by
  Assignee, nor the consummation by Assignee of the transactions contemplated
  thereby and by the Operative Agreements, conflicts with, results in a breach
  of or violates any of the terms, conditions or provisions of (i) the
  [Certificate] [Articles] of Incorporation or By-laws of the Assignee, (ii) to
  the best of my knowledge, any order, writ, injunction or decree of any court
  or government authority against the Assignee or by which the Assignee or any
  of its properties is bound or (iii) to the best of my knowledge, any
  indenture, mortgage or contract or other material agreement or instrument to
  which Assignee is a party or by which it or any of its properties is bound or
  constitutes a default thereunder.

         4. To the best of my knowledge, there are no actions, suits or
  proceedings pending or threatened before any court of administrative agency or
  arbitrator which would materially adversely affect the ability of Assignee to
  perform its obligations under the Assignment Agreement and the Operative
  Agreements.

         5. The Assignment Agreement constitutes a legal, valid and binding
  obligation of Assignee enforceable against Assignee in accordance with the
  terms thereof, except as the enforceability thereof my be limited by (a)
  general equitable principles (regardless of whether such enforceability is
  considered in a proceeding in equity or at law), (b) applicable bankruptcy,
  insolvency, reorganization, moratorium or similar laws affecting the rights of
  creditors generally and (c) public policy considerations (in the case of any
  indemnity provisions contained therein).

         6. Except for filings with the Federal Aviation Administration, neither
  the execution and delivery by Assignee of the Assignment Agreement, nor the
  consummation by Assignee of any of the transactions contemplated thereby or by
  the Operative Agreements, (a) requires the consent or approval of, the giving
  of notice to, or the registration or filing with, or the taking of any action
  with respect to, any governmental authority or agency of the United States or
  (b) violates any law, governmental rule or regulation of the United States of
  the State of [     ].

  B.     I am qualified to practice law in the State of [     ] and I express no
opinion as to any laws other than the laws of the State of [     ], the General
Corporation Law of the State of [     ] and the federal laws of the United
States of America.  I express no opinion herein as to (i) any federal or state
securities laws, (ii) any tax laws or (iii) any aviation law or other laws,
statutes, rules or regulations applicable due to the particular nature of the
equipment subject to the Lease.  In addition, no opinion is expressed as to
matters governed by Title 49 of the United States Code, as amended, or by any
other
<PAGE>

law, statute, rule or regulation or the United States relating to the
acquisition, ownership, registration, use, operation, maintenance, repair,
replacement or sale of or the nature of aircraft. Further, no opinion is
expressed as to title to any part of the Trust Estate. In addition, I express no
opinion as to the perfection or priority of any security interests or as to the
right, title or interest in or to the Trust Estate on the part of any Person.

         This opinion is furnished by me for your sole benefit, and no other
person or entity is entitled to rely on this opinion without my express written
consent. This opinion may not be published or reproduced in any manner or
distributed or circulated to any person or entity without my express written
consent. This opinion is limited to the matter stated herein, and no opinion is
implied or may be inferred beyond the matters expressly stated herein.

                               Very truly yours,

necessary duly to discharge and satisfy in full (i) all Lessor's Liens
attributable to the Owner Trustee in its individual capacity, (ii) any Liens

its individual capacity set forth in Section 6.01) on any part of the Trust
Estate, or on any properties of the Owner Trustee assigned, pledged or mortgaged
as part of the Trust Estate, which arise from acts of the Owner Trustee in its
individual capacity, except the Lien created under the Indenture, the rights of
Lessee under the Lease and the rights of the Owner Participant hereunder, and
(iii) any other Liens or encumbrances attributable to the Owner Trustee in its
individual capacity on any part of the Trust Estate which result from claims
against the Owner Trustee in its individual capacity unrelated to the ownership
of the Aircraft, the administration of the Trust Estate or the transactions
contemplated by the Operative Agreements.

Agreement has been duly authorized, executed and delivered by First Union and
constitutes the legal, valid and binding obligation of First Union enforceable
against it in accordance with its terms, except as such terms may be limited by

Participant or the Indenture Trustee, as the case may be, as duly adopted and in
full force and effect, as conclusive evidence that such resolution has been duly
adopted by said Board and that the same is in full force and effect. As to any
fact or matter the manner of ascertainment of which is not specifically
described herein, the Owner Trustee may, absent actual knowledge to the
contrary, for all purposes hereof rely on a certificate signed by an officer of
Lessee, the Owner Participant or the Indenture Trustee, as the case may be, as
to such fact or matter, and such certificate shall constitute full protection to
the Owner Trustee for any action taken or omitted to be taken by it in good
faith in reliance thereon.

exercise its powers and perform its duties hereunder directly or through agents

                         -----------

filed with respect to the trust created hereby as requested by the Owner
Participant and shall execute and file such returns as directed by the Owner
Participant.

          Section 6.09.  Fixed Investment Trust. Notwithstanding anything herein
                         ----------------------
to the contrary, the Owner Trustee shall not be authorized and shall have no

against any and all liabilities, obligations, losses, damages, penalties, taxes

compensation received by the Owner Trustee for its services hereunder), claims,
actions, suits, costs, expenses or disbursements (including, without limitation,
reasonable legal fees, but excluding internal costs and expenses such as
salaries and overhead) and

expenses of any kind and nature whatsoever which may be imposed on, incurred by
or asserted against the Owner Trustee in its individual capacity (whether or not
also indemnified against by Lessee under the Lease or under the Participation
Agreement or also indemnified against by any other Person; provided that Owner
                                                           --------
Participant shall be subrogated to the rights of Owner Trustee against Lessee or
any other indemnitor) in any way relating to or arising out of this Trust
Agreement or any of the other Operative Agreements or the enforcement of any of
the terms of any thereof, or in any way relating to or arising out of the
manufacture, purchase, acceptance, nonacceptance, rejection, ownership,
delivery, lease, possession, use, operation, condition, sale, return or other
disposition of the Airframe, any Engine or any Part of the foregoing (including,
without limitation, latent and other defects, whether or not discoverable, and
any claim for patent, trademark or copyright infringement), or in any way
relating to or arising out of the administration of the Trust Estate or the
action or inaction of the Owner Trustee hereunder, except (a) in the case of
willful misconduct or gross negligence on the part of the Owner Trustee either
as trustee or in its individual capacity in the performance or nonperformance of
its duties hereunder or under any of the other Operative Agreements to which it
is a party or (b) those resulting from the inaccuracy of any representation or
warranty of the Owner Trustee in its individual capacity (or from the failure of
the Owner Trustee in its individual capacity to perform any covenant) in Section
6.03, or in any of the Operative Agreements, or (c) those arising or resulting
from any of the matters described in the last sentence of Section 6.01, or (d)
those resulting from its failure to perform the terms of the last sentence of
Section 5.04 hereof or from its failure to use ordinary care in the receipt and
disbursement of funds or in connection with its obligation to invest funds
pursuant to Section 15 of the Lease or Section 4.02 hereof or in compliance with
the first Section of Section 6.08, or (e) any liability on the part of Owner
Trustee arising out of its negligence or willful or negligent misconduct in
connection with its obligations under Section 5.01, 6.08 or 9.02 hereof or
Section 4.01 of the Indenture, or (f) those arising under any circumstances or
upon any terms where Lessee would not have been required to indemnify Owner
Trustee, in its individual capacity, pursuant to Section 6.01 or 7.01 of the
Participation Agreement; provided, that before asserting its right to
                         --------
indemnification, if any, pursuant to this Section 7.01, Owner Trustee shall
first demand its corresponding right to indemnification pursuant to Section 6.01
or 7.01 of the Participation Agreement (but need not exhaust any or all remedies
available thereunder). The indemnities contained in this Section 7.01 extend to
the Owner Trustee only in its individual capacity and shall not be construed as
indemnities of the Indenture Estate or the Trust Estate. The indemnities
contained in this Section 7.01 shall survive the termination of this Trust
Agreement and the resignation or removal of the Owner Trustee. In addition, if
necessary, the Owner Trustee shall be entitled to indemnification from the Trust
Estate, subject however to the provisions of Section 4.01 hereof and the Lien
created under the Indenture, for any liability, obligation, loss, damage,
penalty, tax, claim, action, suit, cost, expense or disbursement indemnified
against pursuant to this Section 7.01 to the extent not reimbursed by Lessee,
the Owner Participant or others, but without releasing any of them from their
respective agreements of reimbursement.

Successor. (a) Resignation or Removal. The Owner Trustee or any successor Owner
- ---------
Trustee (i) shall resign if required to do so pursuant to Section 5.02(b) of the
Participation Agreement and (ii) may resign at any time without cause by giving
at least 60 days prior written notice to the Owner Participant, the Indenture
Trustee and Lessee, such resignation to be effective upon the acceptance of

the Owner Participant may at any time remove the Owner Trustee, or revoke the
trusts created by this Trust Agreement, in either case with or without cause by
a notice in writing delivered to the Owner Trustee, the Indenture Trustee and
Lessee. Any such removal shall be effective upon the acceptance of appointment
by the successor Owner Trustee under Section 9.01(b). In the case of the
resignation or removal of the Owner Trustee, the Owner Participant may appoint a
successor Owner Trustee by an instrument in writing. If a successor Owner
Trustee shall not have been appointed within 30 days after such notice of
resignation or removal, the Owner Trustee or the Indenture Trustee may apply to
any court of competent jurisdiction to appoint a successor Owner Trustee to act
until such time, if any, as a successor shall have been appointed as above
provided. Any successor Owner Trustee so appointed by such court shall
immediately and without further act be superseded by any successor Owner Trustee
appointed as above provided within one year from the date of the appointment by
such court.

          (b)  Execution and Delivery of Documents, etc.  Any successor Owner
               -----------------------------------------
Trustee, however appointed, shall execute and deliver to the predecessor Owner
Trustee, with a copy to Owner Participant, Lessee and Indenture Trustee, an
instrument accepting such appointment and assuming the obligations of Owner
Trustee, in its individual capacity and as Owner Trustee, under the Operative
Agreements to which Owner Trustee is a party, and thereupon such successor Owner
Trustee, without further act, shall become vested with all the estates,
properties, rights, powers, duties and trusts of the predecessor Owner Trustee
in the trust hereunder with like effect as if originally named the Owner Trustee
herein; but nevertheless, upon the written request of such successor Owner
Trustee, such predecessor Owner Trustee shall execute and deliver an instrument
transferring to such successor Owner Trustee upon the trusts herein expressed,
all the estates, properties, rights, powers and trusts of such predecessor Owner
Trustee, and such predecessor Owner Trustee shall duly assign, transfer, deliver
and pay over to such successor Owner Trustee all monies or other property then
held by such predecessor Owner Trustee upon the trusts herein expressed.

                                      15

Upon the appointment of any successor Owner Trustee hereunder, the predecessor
Owner Trustee will complete, execute and deliver to the successor Owner Trustee
such documents as are necessary to cause registration of the Aircraft included
in the Trust Estate to be transferred upon the records of the FAA or other
governmental authority having jurisdiction, into the name of the successor Owner
Trustee.

          (c)  Qualification.  Any successor Owner Trustee, however appointed,
               -------------
shall be a Citizen of the United States, shall be qualified to act as a trustee
in Delaware (if the trust created hereby is to remain in such state) and shall
also be a bank or trust company organized under the laws of the United States of
America or any state thereof having a combined capital and surplus of at least
$100,000,000, if there be such an institution willing, able and legally
qualified to perform the duties of the Owner Trustee hereunder upon reasonable
and customary terms.

          (d)  Merger, etc.  Any corporation into which the Owner Trustee may be
               ------------
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which the Owner
Trustee shall be a party, or any corporation to which substantially all the
corporate trust business of the Owner Trustee may be transferred, shall, subject
to the terms of Section 9.01(c), be the Owner Trustee hereunder without further
act; provided that such corporation shall not also be the Indenture Trustee.

          Section 9.02.  Co-Trustees and Separate Trustees. If at any time or
                         ---------------------------------
times it shall be necessary or prudent in order to conform to any Applicable Law
of any jurisdiction in which all or any part of the Trust Estate is located, or
the Owner Trustee shall be advised by counsel that it is so necessary or prudent
in the interest of the Owner Participant or the Owner Trustee, or the Owner
Trustee shall have been directed to do so by the Owner Participant, the Owner
Trustee and the Owner Participant shall execute and deliver an agreement
supplemental hereto and all other instruments and agreements necessary or proper
to constitute another bank or trust company or one or more Persons (any and all
of which shall be a Citizen of the United States) approved by the Owner Trustee
and the Owner Participant, either to act as co-trustee or co-trustees, jointly
with the Owner Trustee, or to act as separate trustee or trustees hereunder (any
such co-trustee or separate trustee being herein sometimes referred to as an
"additional trustee"). In the event (i) the Owner Participant shall not have
joined in the execution of such agreements supplemental hereto within ten days
after the receipt of a written request from the Owner Trustee so to do, or (ii)
an Indenture Event of Default not arising from an Event of Default shall occur
and be continuing, the Owner Trustee may act under the foregoing provisions of
this Section 9.02 without the concurrence of the Owner Participant; and the
Owner Participant hereby appoints the Owner Trustee its agent and attorney-in-
fact to act for it under the foregoing provisions of this Section 9.02 in either
of such contingencies.

          Every additional trustee hereunder shall, to the extent permitted by
Applicable Law, be appointed and act, and the Owner Trustee and its successors
shall act, subject to the following provisions and conditions:

                                      16
<PAGE>

          (a)  all powers, duties, obligations and rights conferred upon the
     Owner Trustee in respect of the custody, control and management of monies,
     the Aircraft or documents authorized to be delivered hereunder or under the
     Participation Agreement shall be exercised solely by the corporation
     designated as the Owner Trustee in the first paragraph of this Trust
     Agreement, or its successors as the Owner Trustee hereunder;

          (b)  all other rights, powers, duties and obligations conferred or
     imposed upon the Owner Trustee and any limitations thereon shall be
     conferred or imposed upon and exercised or performed by the corporation
     designated as the Owner Trustee in the first paragraph of this Trust
     Agreement or its successors as the Owner Trustee, and such additional
     trustee or trustees jointly, except to the extent that under any Applicable
     Law of any jurisdiction in which any particular act or acts are to be
     performed (including the holding of title to the Trust Estate), the Owner
     Trustee shall be incompetent or unqualified to perform such act or acts, in
     which event such rights, powers, duties and obligations shall be exercised
     and performed by such additional trustee or trustees;

          (c)  no power given to, or which it is provided hereby may be
     exercised by, any such additional trustee or trustees shall be exercised
     hereunder by such additional trustee or trustees, except jointly with, or
     with the consent in writing of, the corporation designed as the Owner
     Trustee in this Trust Agreement or its successor as the Owner Trustee,
     anything herein contained to the contrary notwithstanding;

          (d)  no trustee hereunder shall be personally liable by reason of any
     act or omission of any other trustee hereunder;

          (e)  the Owner Participant, at any time, by an instrument in writing
     may remove any such additional trustee. In the event that the Owner
     Participant shall not have joined in the execution of any such instrument
     within ten days after the receipt of a written request from the Owner
     Trustee so to do, the Owner Trustee shall have the power to remove any such
     additional trustee without the concurrence of the Owner Participant; and
     the Owner Participant hereby appoints the Owner Trustee its agent and
     attorney-in-fact to act for it in such connection in such contingency; and

          (f)  no appointing of, or action by, any additional trustee will
     relieve the Owner Trustee of any of its obligations under, or otherwise
     affect any of the terms of the Indenture or affect the interests of the
     Indenture Trustee or the Noteholders in the Trust Estate.

          In case any separate trustee under this Section 9.02 shall die, become
incapable of acting, resign or be removed, the title to the Trust Estate and all
rights and duties of such separate trustee shall, so far as permitted by
Applicable Law, vest in and be exercised by Owner Trustee, without the
appointment of a successor to such separate trustee.

Trustee therefrom; provided, however, that such notice may be given only after
the time the Lien of the Indenture is discharged under Section 9.01 of the
Indenture and after the Lease shall no longer be in effect.

                            - - HABENDUM CLAUSE - -

Indenture Trustee, its successors and assigns, in trust for the benefit and
security of the Noteholders, and for the uses and purposes and subject to the
terms and provisions set forth in this Indenture.

          It is expressly agreed that anything herein contained to the contrary
notwithstanding, the Owner Trustee shall remain liable under the Indenture
Documents to perform all of the obligations assumed by it thereunder, all in
accordance with and pursuant to the terms and provisions thereof, and the
Indenture Trustee and the Noteholders shall have no obligation or liability
under any thereof by reason of or arising out of the assignment hereunder, nor
shall the Indenture Trustee or the Noteholders be required or obligated in any
manner to perform or fulfill any obligations of the Owner Trustee under or
pursuant to any of the Indenture Documents, except as therein or herein
expressly provided, to make any payment, or to make any inquiry as to the nature
or sufficiency of any payment received by it, or present or file any claim, or
take any action to collect or enforce the payment of any amounts which may have

          The Owner Trustee does hereby constitute the Indenture Trustee the
true and lawful attorney of the Owner Trustee, irrevocably, coupled with an
interest and with full power (in the name of the Owner Trustee or otherwise) to
ask, require, demand, receive, compound and give acquittance for any and all
monies and claims for monies (in each case including insurance and requisition

other instruments or orders in connection therewith and to file any claims or to

such purchase to execute and deliver in the name of and on behalf of the Owner
Trustee an appropriate bill of sale and other instruments of transfer relating
to the Airframe and Engines, when purchased by such purchaser, and to perform
all other necessary or appropriate acts with respect to any such purchase, and
in its discretion to file any claim or take any other action or proceedings,
either in its own name or in the name of the Owner Trustee or otherwise, which
the Indenture Trustee may reasonably deem necessary or appropriate to protect
and preserve the right, title and interest of the Indenture Trustee in and to
such Rent and other sums and the security intended to be afforded hereby;
provided no action of the Indenture Trustee pursuant to this paragraph shall
- --------
increase the obligations or liabilities

<PAGE>

of the Owner Trustee to any Person beyond those obligations and liabilities
specifically set forth in this Indenture and the other Operative Agreements.
Under the Lease the Lessee is directed to make all payments of Rent (other than
Excluded Payments) and all other amounts which are required to be paid to or
deposited with the Owner Trustee pursuant to the Lease (other than Excluded
Payments), directly to the Indenture Trustee at such address or addresses as the
Indenture Trustee shall specify, for application as provided in this Indenture.
The Owner Trustee agrees that promptly on receipt thereof, it will transfer to
the Indenture Trustee any and all monies from time to time received by it
constituting part of the Indenture Estate, for distribution by the Indenture
Trustee pursuant to this Indenture.

          The Owner Trustee does hereby warrant and represent that (except as
permitted herein) it has not assigned or pledged any of its right, title, and
interest hereby assigned to anyone other than the Indenture Trustee.

          The Owner Trustee does hereby ratify and confirm the Indenture
Documents and does hereby agree that (except as permitted herein) it will not
take or omit to take any action, the taking or omission of which would result in
an alteration or impairment of any of the Indenture Documents or of any of the
rights created by any thereof or the assignment hereunder.

          The Owner Trustee agrees that at any time and from time to time, upon
the written request of the Indenture Trustee, the Owner Trustee will promptly
and duly execute and deliver any and all such further instruments and documents
as the Indenture Trustee may reasonably request in obtaining the full benefits
of this assignment and of the rights and powers herein granted.

          Notwithstanding the Granting Clause or any of the preceding
paragraphs, there are hereby expressly excluded from the foregoing grant,
bargain, sale, assignment, transfer, conveyance, mortgage, pledge and security
interest all Excluded Payments. Further, nothing in the Granting Clause or any
of the preceding paragraphs shall impair in any respect the rights of the Owner
Trustee or the Owner Participant under Section 5.09.

          IT IS HEREBY COVENANTED AND AGREED by and between the parties hereto
as follows:

                                   ARTICLE 1

                                  DEFINITIONS

          SECTION 1.01. Definitions. For all purposes of this Indenture, terms
                        -----------
defined in the heading and recitals of this Indenture are used as so defined and
capitalized terms used but not defined in this Indenture are used as define in

<PAGE>

Person referenced to herein shall mean such Person and its successors and
permitted assigns. Unless otherwise specified, Section and Article references
are to Sections and Articles of this Indenture.

                                  ARTICLE II

                              THE EQUIPMENT NOTES

          SECTION 2.01. Form of Equipment Notes. The Equipment Notes and the
                        -----------------------

Indenture Trustee's certificate of authentication to appear on the Equipment
Notes shall each be substantially in the form set forth on Exhibit B.

          SECTION 2.02. Terms of Equipment Notes. (a) On the Delivery Date the
                        ------------------------
Owner Trustee shall issue an Equipment Note to the Loan Participant in an
aggregate original principal amount in Dollars equal to the percentage of
Lessor's Cost set forth opposite the Loan Participant's name on Schedule I to
the Participation Agreement. Each Equipment Note shall bear interest on the
unpaid principal amount thereof from time to time outstanding from and including
the date thereof until such principal amount is paid in full at the Applicable
Rate, payable in arrears on each Payment Date and on the date such Equipment
Note is paid in full. Interest hereunder and under the Equipment Notes shall be
calculated on the basis of a year of 360 days consisting of twelve 30-day
months; provided that interest on past due amounts shall be calculated on the
        --------
basis of a year of 360 days and actual days elapsed.

          (b) The principal of the Equipment Notes shall be due and payable on
each Payment Date in the number of installments as noted at Annex A to each
Equipment Note.

          (c) Each Equipment Note shall bear interest at the Past Due Rate on
any principal thereof and, to the extent permitted by Applicable Law, interest
and other amounts due thereunder and hereunder, not paid when due (whether at
stated maturity, by acceleration or otherwise), for any period during which the
same shall be overdue, payable by the Owner Trustee on demand from the
respective Noteholder given through the Indenture Trustee.  Interest under this
clause (c) shall be calculated on the basis of a year of 360 days and the actual
number of days elapsed.

          (d) The Equipment Notes shall be executed on behalf of the Owner
Trustee by one of its authorized officers. Equipment Notes bearing the
signatures of individuals who were at any time the proper officers of the Owner
Trustee shall bind the Owner Trustee, notwithstanding that such individuals or
any of them have ceased to hold such offices prior to the authentication and
delivery of such Equipment Notes or did not hold such offices at the respective
dates of such Equipment Notes. No Equipment Notes shall be issued hereunder
except those provided for in Section 2.02(a) and any Equipment Notes issued in
exchange or replacement therefor pursuant to the terms of this Indenture. The
Equipment Note issued under this Section 2.02 shall be dated the Delivery Date.
No Equipment Note shall be secured by or entitled to any benefit under this
Indenture or be valid or obligatory for any purpose, unless there appears on
such Equipment Note a certificate of authentication in the form provided for
herein executed by the Indenture Trustee by the manual

                                       6
<PAGE>

signature of one of its authorized officers and such certificate upon any
Equipment Note shall be conclusive evidence, and the only evidence, that such
Equipment Note has been duly authenticated and delivered hereunder.

     The principal amount of the Equipment Note issued to the Loan Participant
on the Delivery Date shall not exceed the Loan Participant's Commitment.

          SECTION 2.03. Payments from Indenture Estate Only. Except as otherwise
                        -----------------------------------
expressly provided in the next succeeding sentence of this Section 2.03, all
payments to be made by the Owner Trustee under this Indenture shall be made only
from the income and the proceeds from the Indenture Estate and only to the
extent that the Owner Trustee shall have sufficient income or proceeds from the
Indenture Estate to enable the Owner Trustee to make payments in accordance with
the terms hereof. Each Noteholder, by its acceptance of an Equipment Note, and
the Indenture Trustee, each agrees that it will look solely to the income and
proceeds from the Indenture Estate to the extent available for distribution to
it as above provided and that none of the Owner Participant, the Trust Company
or the Indenture Trustee is personally liable to it for any amounts payable or
any liability under this Indenture or such Equipment Note or for any amounts
payable or liability under any Equipment Note or this Indenture, except, in the
case of the Trust Company and the Indenture Trustee, as expressly provided
herein or in the Participation Agreement; provided, however, that nothing
contained in this Section 2.03 shall be construed to limit the exercise and
enforcement in accordance with the terms of this Indenture or any other
Operative Agreement or such other agreements of rights and remedies against the
Indenture Estate or any such other Person as to their respective obligations to
the Noteholders thereunder.

     The Indenture Trustee hereby waives to the fullest extent permitted by law
the benefit of the provisions of Section 1111(b) of Title 11 of the Bankruptcy
Code with respect to recourse against the Owner Trustee (in its individual
capacity) and the Owner Participant on account of any amount payable as
principal of, Make Whole Amount, if any, and interest on the Equipment Notes,
provided that such waiver shall not preclude the Indenture Trustee from electing
- --------
application of Section 1111(b) (2) of Title 11 of the Bankruptcy Code. The Loan
Participant, each Noteholder and the Indenture Trustee agree that, if (i) the
Trust Estate or the trust created by the Trust Agreement becomes a debtor
subject to the reorganization provisions of the Bankruptcy Code or any other
applicable bankruptcy or insolvency statutes, (ii) pursuant to such
reorganization provision, the Owner Participant is held to have recourse
liability to the Indenture Trustee or any Noteholder directly or indirectly on
account of any amount payable as principal, interest or premium on the Equipment
Notes, and (iii) any Noteholder or the Indenture Trustee actually receives any
Recourse Amount which reflects any payment by the Owner Participant on account
of (ii) above, then such Noteholder or the Indenture Trustee, as the case may
be, shall promptly refund to the Owner Participant such Recourse Amount. For
purposes of this Section 2.03, "Recourse Amount" means the amount by which the
portion of such payment by the Owner Participant on account of clause (ii) above
received by such Noteholder or Indenture Trustee exceeds the amount which would
have been received by such Noteholder or the Indenture Trustee if the Owner
Participant had not become subject to the recourse liability referred to in (ii)
above. Nothing contained in this Section shall

                                       7
<PAGE>

prevent any Noteholder or the Indenture Trustee from enforcing any individual
obligation (and retaining the proceeds thereof) of the Owner Participant under
the Participation Agreement or any other Operative Agreement to the extent
therein provided, for which the Owner Participant has expressly agreed by the
terms of the Participation Agreement to accept individual responsibility.

          SECTION 2.04. Method of Payment. Principal and interest and other
                        -----------------
amounts due hereunder or under the Equipment Notes or in respect hereof or
thereof shall be payable in Dollars in immediately available funds prior to
12:00 noon, New York time, on the due date thereof, to the Indenture Trustee at
its Corporate Trust Department located at the address specified in Section 2.07
and the Indenture Trustee shall, subject to the terms and conditions hereof,
remit all such amounts so received by it to the Noteholders at such account or
accounts at such financial institution or institutions as the Noteholders shall
have designated to the Indenture Trustee in writing (which in the case of the
initial Noteholder shall be the account designated on Schedule II to the
Participation Agreement under the heading "Loan Participant"), in immediately
available funds for distribution to the relevant Noteholders, such payment to be
made, in the case of any such designated account in New York, New York, prior to
2:00 p.m., New York time, on the due date thereof. In the event the Indenture
Trustee, through negligence or willful misconduct, shall fail to make any such
payment as provided in the immediately foregoing sentence after its receipt of
funds at the place and prior to the time specified above, the Indenture Trustee,
in its individual capacity and not as trustee, agrees to compensate the
Noteholders for loss of use of funds in a commercially reasonable manner, and
the Owner Trustee shall have no liability for and the Indenture Estate shall not
secure any such loss or any overdue interest on the Equipment Notes in
connection with any such failure of the Indenture Trustee to timely distribute
funds. All such payments by the Owner Trustee and the Indenture Trustee shall be
made without presentment or surrender of any Equipment Note and free and clear
of and without reduction for account of all wire and other like charges. Prior
to the due presentment for registration of transfer of any Equipment Note, the
Owner Trustee and the Indenture Trustee may deem and treat the Person in whose
name any Equipment Note is registered on the Register as the absolute owner of
such Equipment Note for the purpose of receiving payment of all amounts payable
with respect to such Equipment Note and for all other purposes whether or not
such Equipment Note shall be overdue, and neither the Owner Trustee nor the
Indenture Trustee shall be affected by any notice to the contrary. If any sum
payable under the Equipment Notes or under this Indenture falls due on a day
which is not a Business Day, then such sum shall be payable on the next
succeeding Business Day, without additional interest as a result of such
extension.

          SECTION 2.05. Application of Payments. Each payment of principal and
                        -----------------------
interest or other amounts due in respect of each Equipment Note shall, except as
otherwise expressly provided herein, be applied, first, to the payment of any
                                                 -----
amount (other than the principal of or Make-Whole Amount or interest on such
Equipment Note) due in respect of such Equipment Note, second, to the payment of
                                                       ------
Make-Whole Amount, if any, and interest on such Equipment Note (as well as any
interest on overdue principal and, to the extent permitted by law, interest and
other amounts payable thereunder) due thereunder, third, to the payment of the
                                                  -----
principal of such Equipment Note then due and fourth, the balance, if any,
                                              ------
remaining thereafter, to the payment of the principal of such Equipment Note
remaining unpaid (provided that such Equipment Note shall not be subject to


                                       8
<PAGE>

prepayment or purchase without the consent of the affected Noteholder except as
permitted by Sections 2.10, 2.11, 2.12 and 2.14). The amounts paid pursuant to
clause fourth above shall be applied to the installments of principal of such
Equipment Note in inverse order of maturity.

          SECTION 2.06. Termination of Interest in Indenture Estate. A
                        -------------------------------------------
Noteholder shall not, as such, have any further interest in, or other right with
respect to, the Indenture Estate when and if the principal amount of and Make-
Whole Amount, if any, and interest on and other amounts due under all Equipment
Notes held by such Noteholder and all other sums due to such Noteholder
hereunder and under the other Operative Agreements shall have been paid in full.

          SECTION 2.07. Registration, Transfer and Exchange of Equipment Notes.
                        ------------------------------------------------------
The Indenture Trustee agrees with the Owner Trustee that the Indenture Trustee
shall keep a register (herein sometimes referred to as the "Register") in which
                                                            --------
provisions shall be made for the registration of Equipment Notes and the
registration of transfers of Equipment Notes. The Register shall be kept at the
Indenture Trustee's Corporate Trust Department located at 25 South Charles
Street, Mail Code 101-591, Baltimore, Maryland 21201 or at the office of any
successor indenture trustee, and the Indenture Trustee is hereby appointed the
"Registrar" for the purpose of registering Equipment Notes and transfers of
Equipment Notes as herein provided. Upon surrender for registration of transfer
of any Equipment Note at the Indenture Trustee's Corporate Trust Department, the
Owner Trustee shall execute, and the Indenture Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Equipment Notes of a like aggregate principal amount. At the option of the
Noteholder, its Equipment Notes may be exchanged for other Equipment Notes of
any authorized denominations, of a like aggregate principal amount, upon
surrender of the Equipment Notes to be exchanged at the Indenture Trustee's
Corporate Trust Department. Each new Equipment Note issued upon transfer or
exchange shall be in a principal amount of at least $1,000,000 (except as may be
necessary to evidence the entire outstanding principal amount of an Equipment
Note) and dated the Delivery Date.  Whenever any Equipment Notes are so
surrendered for exchange, the Owner Trustee shall execute, and the Indenture
Trustee shall authenticate and deliver, the Equipment Notes which the Noteholder
making the exchange is entitled to receive. All Equipment Notes issued upon any
registration of transfer or exchange of Equipment Notes shall be the valid
obligations of the Owner Trustee evidencing the same respective obligations, and
entitled to the same security and benefits under this Indenture, as the
Equipment Notes surrendered upon such registration of transfer or exchange.
Every Equipment Note presented or surrendered for registration of transfer or
exchange, shall (if so required by the Owner Trustee or the Indenture Trustee)
be duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Owner Trustee and the Indenture Trustee duly executed by the
Noteholder thereof or his attorney duly authorized in writing, and the Indenture
Trustee may require evidence satisfactory to it as to the compliance of any such
transfer with the Securities Act. The Indenture Trustee shall make a notation on
each new Equipment Note or Equipment Notes of the amount of all payments of
principal previously made on the old Equipment Note or Equipment Notes with
respect to which such new Equipment Note is issued and the date to which
interest accrued on such old Equipment Note or Equipment Notes has been paid.
The Indenture Trustee shall not be required to register the transfer or exchange
of any surrendered

                                       9
<PAGE>

Equipment Notes as above provided during the ten (10) Business Day period
preceding the due date of any payment on such Equipment Notes. Any Noteholder
may transfer any or all of its Equipment Notes to any Person other than the
Lessee or its Affiliates. The Owner Trustee and the Indenture Trustee shall
treat the Person in whose name each Equipment Note is registered on the Register
as the Noteholder with respect thereto for all purposes hereof until due
presentment for registration of transfer as provided in this Section 2.07. The
Indenture Trustee shall give the Lessee and each Noteholder prompt notice of
such transfer of an Equipment Note under this Section 2.07. Each holder of an
Equipment Note, by its acceptance thereof, agrees that any transfer of any
Equipment Note acquired by it hereunder shall not be effected unless the
transferee shall have delivered to the Indenture Trustee, the Lessee, the Owner
Participant and the Owner Trustee (i) a representation as to the matters
specified in Section 5.08 of the Participation Agreement and, notwithstanding
the above, such transferee by its acceptance of an Equipment Note shall be
deemed to have made such a representation and (ii) an agreement to be bound by
and comply with the provisions of the Participation Agreement and this Indenture
binding on a Loan Participant and, notwithstanding the above (but without
derogation to the requirements for delivery of such agreement), such transferee
by its acceptance of an Equipment Note shall be deemed to have made such
representations and such agreement.

          SECTION 2.08. Mutilated, Destroyed, Lost or Stolen Equipment Notes. If
                        ----------------------------------------------------
any Equipment Note shall become mutilated, destroyed, lost or stolen, the Owner
Trustee shall, upon the written request of the affected Noteholder, execute, and
the Indenture Trustee shall authenticate and deliver in replacement thereof, a
new Equipment Note in the same principal amount, dated the date of such
Equipment Note and designated as issued under this Indenture. If the Equipment
Note being replaced has become mutilated, such Equipment Note shall be
surrendered to the Indenture Trustee. If the Equipment Note being replaced has
been destroyed, lost or stolen, the affected Noteholder shall furnish to the
Owner Trustee and the Indenture Trustee such security or indemnity as may be
reasonably required by them to hold the Owner Trustee and the Indenture Trustee
harmless and evidence satisfactory to the Owner Trustee and the Indenture
Trustee of the destruction, loss or theft of such Equipment Note and of the
ownership thereof; provided, however, that if the affected Noteholder is an
                   --------  -------
original party to the Participation Agreement or an Affiliate thereof, the
written notice of such destruction, loss or theft and such ownership and the
written undertaking of such Noteholder delivered to the Owner Trustee and the
Indenture Trustee to hold harmless the Owner Trustee and the Indenture Trustee
in respect of the execution, authentication and delivery of such new Equipment
Note shall be sufficient evidence, security and indemnity.

          SECTION 2.09. Payment of Expenses on Transfer. Upon the issuance of a
                        -------------------------------
new Equipment Note or new Equipment Notes pursuant to Section 2.07 or 2.08, the
Owner Trustee and/or the Indenture Trustee may require from the party requesting
such new Equipment Note or Equipment Notes payment of a sum sufficient to
reimburse the Owner Trustee and/or the Indenture Trustee for, or to provide
funds for, the payment of any tax or other governmental charge in connection
therewith or any charges and expenses connected with such tax or other
governmental charge paid or payable by the Owner Trustee or the Indenture
Trustee.

          SECTION 2.10. Prepayment. (a) The Owner Trustee may, in accordance
                        ----------
with Section 2.10(b), if requested to do so by the Lessee and upon no less than
30 days' prior irrevocable notice to the Indenture Trustee and the original
Noteholder (so long as it holds an Equipment Note), on any date on or after the
fifth anniversary of the Delivery Date prepay in whole but not in part the
Equipment Notes then outstanding (except in the case of a prepayment which
occurs after a Noteholder has requested the payment of (x) any Increased Costs
pursuant to Section 2.14(a) or (y) any amounts pursuant to Article 6 of the
Participation Agreement in respect of withholding Taxes, in which case such
prepayment, if elected to be made by the Owner Trustee, may be made at any time)
at the principal amount thereof, together with accrued interest thereon to the
date of prepayment plus the Make-Whole Amount (if any) and all other amounts due
to the holders of the Equipment Notes hereunder, thereunder and under the other
Operative Agreements.

           (b) The Equipment Notes shall be prepaid in full but not in part,
together with accrued interest thereon to the date of prepayment and all other
amounts due thereunder and hereunder and under the other Operative Agreements to
the Noteholders:

           (i) Upon the occurrence of an Event of Loss with respect to the
     Airframe (unless pursuant to Section 8(a)(i) of the Lease and Section 5.06
     a Replacement Airframe, together with the same number of Replacement
     Engines as the Engines, if any, subject to such Event of Loss, shall have
     been substituted for the Airframe and/or the Engines subject to such Event
     of Loss), on the earlier of the date of the Lessee's payment with respect
     to such Event of Loss in Section 8(a)(ii) of the Lease and the last day
     permitted for such payment under said Section 8(a)(ii);

          (ii) Upon the Lessee's election to terminate the Lease with respect to
     the Aircraft as provided in Section 14(a) of the Lease, on the Termination
     Date of the Lease as provided in said Section 14(a);

          (ii) Upon the Lessee's election to purchase the Aircraft on the EBO
     Date as provided in Section 13(b) of the Lease, on the date of such
     purchase as provided in said Section 13(b) of the Lease (unless Lessee has
     assumed the Owner Trustee's obligations pursuant to and in accordance with
     Section 5.10 of the Participation Agreement); and

          (iv) Upon the Lessee's election to refinance the Equipment Notes as
     provided in Section 13.01 of the Participation Agreement, and upon no less
     than 30 days' prior notice to the Indenture Trustee, on the closing date of
     such refinancing as provided in said Section 13.01 of the Participation
     Agreement.

The Owner Trustee will give notice of prepayment under this Section 2.10(b) to
Indenture Trustee and the original Noteholder (so long as it holds an Equipment
Note) promptly after receipt of the Lessee's notice of payment under Section
8(a)(ii), 13(b) or 14(a) of the Lease, or refinancing under Section 13.01 of the
Participation Agreement, as the case may be. Any prepayment of the Equipment

                                      11
<PAGE>

Notes pursuant to clause (ii), clause (iii) or clause (iv) of this Section
2.10(b) (but not clause (i)) shall be accompanied by the Make-Whole Amount (if
any) for each Noteholder.

          SECTION 2.11. Provisions Relating to Prepayment. (a) The Owner Trustee
                        ---------------------------------
shall have no right to prepay the principal amount of the Equipment Notes, in
whole or in part, or purchase the Equipment Notes except as permitted by
Sections 2.10, 2.11, 2.12 and 2.14. Any such prepayment shall, except as
otherwise expressly provided in this Indenture, Section 13.01 of the
Participation Agreement or Section 13(b) of the Lease, as the case may be, be
made by the Owner Trustee only on a date coincident with a Termination Date and
upon notice to the Indenture Trustee, the Noteholders and the Lessee provided
for in Section 2.10 or in Section 8(a)(ii) or 14(a) of the Lease, as the case
may be. Notice of prepayment having been given as aforesaid, the principal
amount of the Equipment Notes so to be prepaid, plus accrued interest thereon to
the date of prepayment, together with the Make-Whole Amount, if any, if required
to be paid as herein provided, shall become due and payable on the prepayment
date; provided, however, with respect to any prepayment under Section 2.10(b),
      --------  -------
if any applicable notice of termination is timely revoked (or if the Lease does
not in fact so terminate) pursuant to Section 14 of the Lease or if all amounts
due and payable pursuant to Section 8(a)(ii), 13(b) or 14(a) of the Lease, or
Section 13.01 of the Participation Agreement, as the case may be, are not paid
or the refinancing is not consummated pursuant to Section 13.01 of the
Participation Agreement, or if the Lessee assumes the Owner Trustee's
obligations under the Equipment Notes and this Indenture pursuant to and in
accordance with Section 5.10 of the Participation Agreement, then the principal
amount of the Equipment Notes shall not be deemed to have been due and no Make-
Whole Amount, if any, shall be payable as a result thereof.

           (b) On the date fixed for prepayment under Section 2.10, immediately
available funds in Dollars shall be deposited by the Owner Trustee in the
account of the Indenture Trustee at the place and by the time and otherwise in
the manner provided in Section 2.04, in an amount equal to the principal amount
of Equipment Notes to be prepaid together with accrued and unpaid interest
thereon to the date fixed for such prepayment, all Make-Whole Amount, if any,
and all other amounts due to the holders of the Equipment Notes hereunder,
thereunder and under the other Operative Agreements.

          SECTION 2.12. Purchase Upon an Event of Default. At any time while (x)
                        ---------------------------------
an Event of Default (without regard to any waiver thereof by the Indenture
Trustee) has occurred and has been continuing for a period of 190 days during
which the Noteholders or the Indenture Trustee shall not have been stayed or
otherwise precluded by operation of law from taking action to accelerate the
Equipment Notes or to exercise remedies hereunder or under the Lease and shall
not, during such 190 day period, have taken any such action or exercised any
such remedy, or (y) the Equipment Notes shall have become due and payable as
provided in Section 4.04(b) or 4.04(c) or (z) an Event of Default (without
regard to any waiver thereof by the Indenture Trustee) has occurred and is
continuing, the Owner Participant may, at any time within 120 days after such
190-day period in the case of clause (x) above, at any time after the Equipment
Notes have become due in the case of clause (y) above and at any time during
which such Event of Default shall have occurred and been

                                      12
<PAGE>

continuing in the case of clause (z) above but (in the case of clauses (x) and
(z)) so long as no Indenture Event of Default which is not a, or does not arise
out of a, Default or Event of Default has occurred and be continuing, elect to
purchase all, but not less than all, Equipment Notes then outstanding (at par
plus, solely in the case of clause (z) above, the Make-Whole Amount); and
provided, that the Owner Participant may not so purchase the Equipment Notes in
- --------
accordance with the foregoing at any time on or after the fifteenth (15th)
Business Day following receipt by it of notice of a proposed sale or disposition
of the Indenture Estate or any portion thereof, the Equipment Notes or any
interest of the Noteholders in the Trust Estate. Upon receipt of written notice
of such election from the Owner Participant, which notice in order to be
effective shall state that it is irrevocable (and shall constitute a recourse
obligation of Owner Participant) and shall designate a date not more than
fourteen calendar days thereafter as the purchase date, each Noteholder agrees
that it will, upon payment to it in the manner provided for in Section 2.04 from
the Owner Participant of an amount equal to the aggregate unpaid principal
amount of all Equipment Notes then held by such Noteholder (at par plus, solely
in the case of clause (z) above, the Make-Whole Amount), together with accrued
and unpaid interest thereon to the date of payment, plus all reasonable expenses
                                                    ----
of the Indenture Trustee or such Noteholder associated therewith (and all other
sums then due and payable to such Noteholder hereunder, under such Equipment
Notes and the other Operative Agreements), forthwith sell, assign, transfer and
convey to the Owner Participant (without recourse, representation or warranty of
any kind except for its own acts), all of the right, title and interest of such
Noteholder in and to the Indenture Estate, this Indenture, all Equipment Notes
held by such Noteholder and the other Operative Agreements (excluding all right,
title and interest under any of the foregoing to the extent such right, title or
interest is with respect to an obligation not then due and payable or past due
(other than any claims in respect of past due interest or other amounts to the
extent included in the purchase price of the Equipment Notes), with respect to
any action or inaction or state of affairs occurring or existing prior to such
sale) and the Owner Participant shall assume all of such Noteholder's
obligations under the other Operative Agreements and this Indenture arising
subsequent to such purchase and sale. The Indenture Trustee shall not exercise
any remedies hereunder and, without the consent of the Owner Participant, under
the Lease, during the period from the time of receipt of such notice of such
election until the date on which such purchase is required to occur pursuant to
the terms of the preceding sentence. If the Owner Participant shall so request,
such Noteholder will comply with all the provisions of Section 2.07 (other than
those relating to Securities Act compliance and those obligations set out in the
last sentence of Section 2.07) to enable new Equipment Notes to be issued to the
Owner Participant in such denominations as the Owner Participant shall request.
In the case of any such purchase, upon the request of any Noteholder the Owner
Participant shall furnish to the Noteholders evidence that such transfer and
conveyance are exempt from registration under the Securities Act, and do not
violate any registration provision of any applicable state securities laws
(which evidence may include an opinion of counsel for the Owner Participant
satisfactory to the Noteholders). All charges and expenses required pursuant to
Section 2.09 in connection with the issuance of any such new Equipment Note
pursuant to this Section shall be borne by the Owner Participant.

          SECTION 2.13. Equipment Notes in Respect of Replacement Aircraft. Upon
                        --------------------------------------------------
the execution and delivery of an Indenture Supplement covering a Replacement
Airframe and/or

                                      13
<PAGE>

Replacement Engine, as provided in Section 5.06, each Equipment Note shall be
deemed to have been issued in connection with such Replacement Airframe and/or
Replacement Engine and each Equipment Note issued thereafter upon a transfer or
exchange of, or as a replacement for, an Equipment Note, shall be designated as
having been issued in connection with such Replacement Airframe and/or
Replacement Engine, but without any other change therein except as provided for
in this Article II.

          SECTION 2.14.  Increased Costs.   (a)  If the enactment, adoption or
                         ---------------
promulgation, after the Delivery Date, of any applicable law or regulation or
any change, after the Delivery Date, in any applicable law, rule, regulation,
guidance or ruling or any exceptions thereto (or any applicable published
change, after the Delivery Date, in the interpretation thereof (whether or not
having force of law) or any compliance by a Noteholder with any request from
such authority (provided that the observance thereof is in accordance with the
reasonable practice of lenders in the country concerned)) of general
applicability by any governmental, fiscal, monetary or other authority charged
with the administration or application thereof (in each of the foregoing cases
which is binding upon such Noteholder, in any applicable jurisdiction for
purposes of funding or maintaining any Equipment Note or the participation by
such Noteholder in the transactions contemplated hereby and by the other
Operative Agreements), shall:

                 (i)  impose, modify, or deem applicable any reserve, special
     deposit or similar requirement (including, without limitation, any such
     requirement imposed by the Board of Governors of the Federal Reserve
     System, but excluding any such requirement with respect to which such
     Noteholder is entitled to compensation during the relevant interest period
     and excluding any regulatory change the effect of which is the
     implementation of the Basle Accord as in effect on the date hereof) against
     deposits with, or credit extended by, such Noteholder by reason of the
     funding or maintaining of its Equipment Note;

                (ii)  impose, modify or deem applicable a capital adequacy
     requirement which such Noteholder can establish has the effect of
     increasing the amount of capital required to be maintained by such
     Noteholder, but only to the extent that such increase is directly
     attributable and allocable to such Noteholder's obligations to fund and
     maintain its Equipment Note; or

               (iii)  impose, modify or deem applicable any tax (not excluded
     from indemnification under Article 6 of the Participation Agreement), or
     other governmental, monetary or other charge or other condition which in
     each case is in the nature of such reserve, special deposit or similar
     requirement;

and the result of any of the foregoing shall be to increase in the aggregate and
by a material amount the costs to such Noteholder, but only to the extent that
such increase is directly attributable and allocable to funding and maintaining
the Equipment Notes (any such reserve, special deposit, similar requirement, tax
or other governmental, monetary or other charge or condition or capital adequacy
cost hereinafter collectively referred to as an "Increased Cost") and provided,
that in assessing the

                                      14
<PAGE>

effect of such enactment, adoption or change or condition and determining such
Increased Cost, such Noteholder shall evaluate and apply the requirements in
respect of its Equipment Notes hereunder in a manner which is no less favorable
to the Lessee than, and shall not discriminate in such evaluation and
application in relation to, and with respect to clauses (i) or (iii) above, the
other deposits with or credit extended by the Noteholder involving any other
Persons, and with respect to clause (ii) above, comparable funding obligations
held by the Noteholder of the same type and category involving other Persons,
then the Noteholder shall promptly provide the Owner Trustee and the Lessee with
written notice of such event giving rise to such Increased Cost. Such notice
shall be accompanied by an Officer's Certificate describing in reasonable detail
(a) the events giving rise to such Increased Cost, (b) the basis for determining
and allocating such Increased Cost with respect to the Equipment Notes held by
such Noteholder and a statement to the effect that the determination for such
Increased Costs in connection with its obligations under this transaction has
been made in a manner that does not discriminate against the Owner Trustee or
the Lessee, and (c) a good faith estimate of the amount expected to be incurred
by the Noteholder (such estimate to set out in reasonable detail the basis on
which it has been prepared).

     Within thirty (30) days of the receipt of an invoice for Increased Cost
incurred following (or accompanying such notice), the Owner Trustee shall remit
the amount due to such Noteholder.

     Notwithstanding any of the provisions hereof, such Noteholder shall not be
entitled to serve notice to cause a payment of Increased Cost if (i) the
Noteholder (or any office, branch or affiliate thereof) incurred the relevant
Increased Cost as a result of the Noteholder's (or any office, branch or
affiliate thereof) having acted in a manner contrary to, or failed to act in a
manner required by, the Applicable Laws or (ii) the relevant Increased Cost was
imposed with respect to the period prior to receipt by the Owner Trustee and the
Lessee of the notice with respect thereto pursuant to the first paragraph of
this Section.

          (b) Upon the receipt of any notice of Increased Cost, the Noteholder
and the Lessee shall consult in good faith and the Noteholder shall use its
reasonable best efforts to avoid or mitigate the amount of any Increased Cost,
including without limitation, by assigning the rights and obligations of the
Noteholder hereunder (if other than the Loan Participant) to another office,
branch, subsidiary or affiliate of the Noteholder or by selling or transferring
the rights, interests and obligations of the Noteholder hereunder or under any
other Operative Agreement to another bank, financial or lending institution,
subject to the terms hereof, that would not be subject to any such Increased
Cost, provided that the Noteholder shall not be required to take such action to
avoid or mitigate such Increased Cost hereunder if such action would result in
any economic, legal or regulatory disadvantage, or any adverse tax consequence
to the Noteholder (other than (i) economic disadvantage for which the Lessee
agrees to indemnify the Noteholder on an After Tax Basis and in a manner
reasonably acceptable to the Noteholder, or (ii) adverse tax consequences for
which the Lessee agrees to indemnify the Noteholder on an After Tax Basis and in
a manner reasonably acceptable to the Noteholder).

                                      15
<PAGE>

          (c) The Owner Trustee shall not be required to make payments under
this Section to any Noteholder if (i) a claim hereunder arises through
circumstances peculiar to such Noteholder and which do not affect commercial
lenders in the same jurisdiction generally, (ii) the claim arises out of a
voluntary relocation by such Noteholder of its lending office, (iii) such
Noteholder is not also seeking indemnification against similar increased costs,
to the extent it is entitled to do so, in transactions with substantial
borrowers (it being agreed that an Officer's Certificate to the contrary from
any such Noteholder shall constitute conclusive evidence of such fact), (iv) a
claim is directly attributable to any corresponding claim for Increased Cost
which is made on such Noteholder by any Person which has funded such
Noteholder's purchase of its Equipment Notes or (v) such Noteholder is the Loan
Participant.

     amounts) then due on or in respect of the Equipment Notes shall be
     distributed to the holders thereof ratably, without priority of any one
     Equipment Note over any other Equipment Note, in the proportion that the
     amount of such payment or payments then due under each Equipment Note bears
     to the aggregate amount of the payments then due under all Equipment Notes;

          second, the balance, if any, of such installment or payment remaining
          ------
     thereafter shall be distributed to the Owner Trustee for distribution

          SECTION 3.08.  Taxes; Withholding. The Indenture Trustee agrees, to
                         ------------------
the extent required by applicable law, to withhold from each payment due
hereunder or under any Equipment Note, United States withholding taxes at the
appropriate rate, and, on a timely basis, to deposit such amounts with an
authorized depository and make such filings and other reports in connection
therewith, and in the manner required under applicable law. The Indenture
Trustee shall promptly furnish to each Noteholder that is a Non-U.S. Person (as
defined below) (but in no event later than the date 30 days after the due date
thereof) a U.S. Treasury Form 1042S (or similar forms as at any relevant time in
effect), if applicable, indicating payment in full of any Taxes withheld from
any payments by the Indenture Trustee to such persons together with all such
other information and documents reasonably requested by the Noteholder and
necessary or appropriate to enable each Noteholder to substantiate a claim for
credit or deduction with respect thereto for income tax purposes of the country
where each Noteholder is located. In the case of a Noteholder that is a Non-U.S.
Person (as defined below), the Noteholder shall provide the Indenture Trustee
with such forms and other documentation (collectively, "Tax Forms") as may be
necessary or desirable to enable such Noteholder to claim an exemption from, or
reduced rate of, such taxes and provided that such Noteholder has furnished the
Indenture Trustee with the requested Tax Forms and has not notified the
Indenture Trustee of the withdrawal or inaccuracy of any Tax Forms prior to the
date of each interest payment, only the reduced amount (if any) required by
applicable law or treaty shall be withheld from payments under the Equipment
Notes held by such Noteholder. Provided that each Noteholder that is a Non-U.S.
Person has furnished to the Indenture Trustee either (x) a properly completed
and currently effective U.S. Treasury Form 1001 or U.S. Treasury Form W-8 (or
such successor forms as may be required by the United States Treasury Department
establishing a complete exemption from or a reduced rate of United States
federal withholding Taxes) during the calendar year in which the payment is made
or in either of the two preceding calendar years (or such longer or shorter
period as may be required by the United States Treasury Department), and has not
notified the Indenture Trustee of the withdrawal of such Form prior to the date
of each interest payment, or (y) a properly completed and currently effective
U.S. Treasury Form 4224 (or such successor form as may be required by the United
States Treasury Department) or other certificate or form establishing a complete
exemption from or a reduced rate of United States federal withholding Taxes
during each calendar year before the first payment for the year is made and has
not notified the Indenture Trustee of the withdrawal of such Form or certificate
prior to the date of each interest payment, then no amount or only one reduced
amount required by applicable law shall be withheld from payments under the
Equipment Notes held by such Noteholder in respect to United States federal
income tax. In the case of a Noteholder that is not a Non-U.S. Person that has
furnished to the Indenture Trustee a properly completed and currently effective
U.S. Treasury Form W-9, no amount shall be withheld from payments under the
Equipment Notes held by such Noteholder in respect of United States federal
income tax. If any Noteholder has notified the Indenture Trustee that any of the
foregoing forms or certificates is withdrawn or inaccurate, or if the Internal
Revenue Code or the regulations thereunder or the administrative interpretation
thereof are at any time after the date hereof amended to require such
withholding of United States federal

                                      21
<PAGE>

income taxes from payments under the Equipment Notes held by such Noteholder, or
if such withholding is otherwise required, the Indenture Trustee agrees to
withhold from each payment due to the relevant Noteholder withholding taxes at
the appropriate rate under applicable law, and will, as more fully provided
above, on a timely basis, deposit such amounts with an authorized depository and
make such reports, filings and other reports in connection therewith, and in the
manner required under applicable law. For the purpose hereof, a "Non-U.S.
Person" is a person who is not a "United States Person" as such term is defined
in Section 7701(a)(30) of the Code.

     individual capacity) or the Owner Participant or any Owner Participant
     Guarantor shall (i) be generally not paying its debts as they become due,
     (ii) file, or consent by answer or otherwise to the filing against it of, a
     petition for relief or reorganization or arrangement or any other petition

     approving a petition for relief or reorganization or any other petition in

     or liquidation of the Trust Estate or the Owner Trustee (not in its

     Guarantor, or if any petition for any such relief shall be filed against
     the Trust Estate or the Owner Trustee (not in its individual capacity) or
     the Owner Participant or any such Owner Participant Guarantor, and such
     petition shall not be dismissed within, or the order shall be unstayed and

               (i) any failure by the Trust Company to give notice, or to
     resign, if required by Section 5.02(b) of the Participation Agreement, or
     (if the Trust Company shall have given such notice and resigned as required
     by said Section 5.02(b)) a successor Owner Trustee shall not have been
     appointed and qualified within 30 days after the Trust Company's ceasing to
     be a "Citizen of the United States", unless such failure does not adversely
     affect the Lien of this Indenture; or

               (j) the Owner Trustee, the Trust Company or the Owner Participant
     shall do or fail to do any act, or shall fail to meet any condition, and as
     a result thereof the Lien of this Indenture shall cease to be a valid first
     priority Lien on the Indenture Estate, unless such failure is caused by a
     Default or Event of Default; or

               (k) any disaffirmation or repudiation by any Owner Participant
     Guarantor of its obligations under its Owner Participant Guaranty.

Notwithstanding any provision of Section 4.02(g) or (h) to the contrary, if the
bankruptcy, reorganization, compromise, arrangement, insolvency, readjustment of
debt, dissolution or liquidation of the Trust Company shall have caused an
Indenture Default under Section 4.02(g) or (h), then no such Indenture Default
shall be deemed to have occurred so long as the Owner Participant is diligently
seeking to, and does replace the Trust Company then serving as Owner Trustee
within forty-five days after the date of such Indenture Event of Default;
provided, however, the Owner Participant shall not be entitled to cure such an
- --------  -------
Indenture Event of Default by replacing the then existing Owner Trustee, if the
Indenture Trustee's rights in the Indenture Estate or any material portion
thereof, in the reasonable judgment of the Indenture Trustee or a Majority in
Interest of Noteholders, would be impaired either by such forty-five (45) day
delay (or any portion thereof) or by the Owner Participant's replacing the Owner
Trustee.

          SECTION 4.03  Certain Cure Rights. Upon an Event of Default in payment
                        -------------------
of any installment of Basic Rent due under the Lease, the Owner Participant may,
but shall not be required to, within 10 Business Days after such Event of
Default, without the consent or concurrence of any Noteholder, pay, as provided
in Section 2.04, for application in accordance with Section 3.01 a sum equal to
the amount of all (but not less than all) principal and accrued interest
(including

                                      25
<PAGE>

interest, if any, on overdue payments of principal and interest) then due on the
Equipment Notes and payable out of such overdue Basic Rent. In the event of any
default by the Lessee in any obligation under the Lease other than the payment
of Basic Rent, if such default can be remedied by the payment of money and the
Owner Participant shall furnish the Owner Trustee with all funds necessary for
remedying such default, the Owner Participant may, within thirty (30) days after
the expiry of the applicable grace period specified in the Lease with respect to
such default, without the consent or concurrence of any Noteholder, instruct the
Owner Trustee to exercise the Owner Trustee's rights under Section 18 of the
Lease to perform such obligation on behalf of the Lessee. Solely for the purpose
of determining whether there exists an Indenture Event of Default, (a) any
timely payment by the Owner Participant pursuant to, and in compliance with, the
first sentence of this Section 4.03 shall be deemed to remedy (but solely for
purposes of this Indenture) any default by the Lessee in the payment of
installments of Basic Rent theretofore due and payable and to remedy (but solely
for purposes of this Indenture) any default by the Owner Trustee in the payment
of any amount of principal and interest due and payable under the Equipment
Notes and (b) any timely performance by the Owner Trustee of any obligation of
the Lessee under the Lease pursuant to, and in compliance with, the second
sentence of this Section 4.03 shall be deemed to remedy (but solely for purposes
of this Indenture) any Event of Default to the same extent that like performance
by the Lessee itself would have remedied such Event of Default (but no such
remedy shall relieve the Lessee of its duty to pay all Rent and perform all of
its obligations pursuant to the Lease). If, on the basis specified in the
preceding sentence, any Events of Default shall have been remedied, then any
declaration pursuant to this Indenture that the Equipment Notes are due and
payable or that an Indenture Event of Default exists hereunder, based solely
upon such Events of Default, shall be deemed to be rescinded, and the Owner
Participant shall (to the extent of any such payments made by it) be subrogated
to the rights of the holders of the Equipment Notes under Section 3.01(a), to
receive from the Indenture Trustee such payment of overdue Rent (and the payment
of interest on account of such Rent being overdue) and shall be entitled, so
long as no other Indenture Event of Default or Indenture Default shall have
occurred and be continuing or would result therefrom, to receive, subject to the
provisions of this Indenture, such payment upon receipt thereof by the Indenture
Trustee; provided that the Owner Participant shall not otherwise attempt to
         --------
recover any such amount paid by it on behalf of the Lessee pursuant to this
Section 4.03 except by demanding of the Lessee payment of such amount or, so
long as such action is not inconsistent with any remedy then being exercised
against Lessee under or pursuant to the Lease, by commencing an action at law
against the Lessee for the payment of such amount; provided, further, that at no
                                                   --------  -------
time while an Indenture Event of Default (other than an Indenture Event of
Default which is a, or arises out of a, Default or Event of Default) shall have
occurred and be continuing shall any such demand be made or shall any such
action be commenced (or continued) and such subrogation shall be subordinate to
the rights of the Indenture Trustee and the Noteholders in respect of such
payment, and during any such period any amounts nevertheless received by the
Owner Participant in respect thereof shall be held in trust for the benefit of,
and promptly paid to, the Indenture Trustee for distribution as provided in
Section 3.03; and further provided that:
                  ------- --------

          (x) this Section 4.03 shall not apply with respect to any default in
     the payment of Basic Rent due under the Lease if the Lessee itself shall
     have theretofore failed to pay

                                      26
<PAGE>

     Basic Rent in the manner required under the Lease (after giving effect to
     any applicable grace period) on (i) each of the two Basic Rent Payment
     Dates immediately preceding the date of such default, or (ii) a total of
     five Basic Rent Payment Dates (including, solely for the purposes of this
     paragraph (x), the Delivery Date as a Basic Rent Payment Date);

          (y) the second sentence of this Section 4.03 shall cease to apply, and
     no payment by the Owner Participant in respect of Supplemental Rent or
     performance of any obligation of the Lessee under the Lease by the Owner
     Trustee shall be deemed to remedy or to have remedied any Event of Default
     for the purposes of this Indenture, if during the Term there shall have
     been expended by the Owner Participant pursuant to the second sentence of
     this Section 4.03 (and which shall have not been reimbursed by the Lessee
     itself to the Owner Trustee for distribution to the Owner Participant) an
     amount in the aggregate in excess of $1,000,000; and

          (z) neither the Owner Trustee nor the Owner Participant shall have the
     right to cure any Event of Default except as specified in this Section
     4.03.

Except as hereinafter in this Section 4.03 provided during any period prior to
satisfaction of all Secured Obligations, the Owner Trustee shall not, as a
result of exercising the right to remedy any such Event of Default, obtain any
Lien on any of the property included in the Indenture Estate or any Rent payable
under the Lease for or on account of costs or expenses incurred in connection
with the exercise of such right, nor shall any claim of the Owner Trustee
against the Lessee or any other party for the repayment of such costs or
expenses impair the prior right and security interest of the Indenture Trustee
in and to any of the property in the Indenture Estate.

          SECTION 4.04.  Remedies.  (a) If an Indenture Event of Default shall
                         --------
have occurred and be continuing and so long as the same shall be continuing
unremedied, then and in every such case, the Indenture Trustee may, consistent
with this Section 4.04(a), exercise any or all of the rights and powers and
pursue any and all of the remedies pursuant to this Article IV and shall have
and may exercise all of the rights and remedies of a secured party under the
Uniform Commercial Code and, in the event such Indenture Event of Default is an
Indenture Event of Default referred to in paragraph (a) of Section 4.02 and
Section 4.03 shall either not apply or shall have ceased to apply with respect
to the relevant Event of Default, any and all of the remedies pursuant to
Section 17 of the Lease and all of the rights and remedies of a lessor under
applicable law and may take possession of all or any part of the properties
covered or intended to be covered by the Lien and security interest created
hereby or pursuant hereto and may exclude the Owner Participant, the Owner
Trustee and the Lessee and all persons claiming under any of them wholly or
partly therefrom. The Indenture Trustee agrees to give the Owner Trustee at
least 10 days' written notice of the date fixed for any public sale of the
Indenture Estate or of the date on or after which will occur the execution of
any contract providing for any private sale of the Indenture Estate (which
notice the parties hereto agree shall constitute commercially reasonable notice
under applicable law). At any sale of the Indenture Estate or any part thereof,
the Owner Trustee or the Owner Participant may bid for and purchase such
property. Without limiting any of the foregoing, it is understood and

                                      27
<PAGE>

agreed that the Indenture Trustee may exercise any right of sale of the Aircraft
available to it, even though it shall not have taken possession of the Aircraft
and shall not have possession thereof at the time of such sale. It is further
understood and agreed that if the Indenture Trustee shall proceed to foreclose
the Lien of this Indenture in respect of an Indenture Event of Default referred
to in paragraph (a) of Section 4.02, it shall, to the extent that it is then
entitled to do so hereunder and under the Lease, and is not then stayed or
prevented from doing so by operation of law or otherwise, proceed (to the extent
it has not already done so) to exercise one or more of the remedies referred to
in Section 17(a), (b), (c), (d) or (e) of the Lease (to the extent that any such
remedy referred to in Section 17(e)(ii) is comparable to any remedy referred to
in such Section 17(a), (b), (c), (d) or (e)(i) of the Lease) as it shall
determine in its sole good faith discretion or as it shall be directed by a
Majority in Interest of the Noteholders; provided that, if the Indenture Trustee
                                         --------
is so stayed or prevented, it will not be entitled to proceed to foreclose the
Lien of this Indenture until the earlier of (x) actual repossession of the
Aircraft from the Lessee or the Owner Trustee, as the case may be, or (y) the
expiration of the Section 1110 Period (as hereafter defined); and for the
avoidance of doubt, it is expressly understood and agreed that, subject to the
immediately preceding proviso and to the immediately following proviso, the
above-described inability of the Indenture Trustee to exercise any right or
remedy under the Lease shall in no event and under no circumstance prevent the
Indenture Trustee from exercising all of its rights, powers and remedies under
this Indenture, including without limitation this Article IV; provided, further,
                                                              --------  --------
that the Indenture Trustee shall not foreclose upon or divest the Owner Trustee
of title to the Aircraft or the Lease in the event the Lessee (or the bankruptcy
trustee or debtor-in-possession) with the approval of the relevant court either
agrees to perform the Lease in accordance with Section 1110 of the Bankruptcy
Code or assumes the Lease in accordance with Section 365 of the Bankruptcy Code,
but only so long as the Lessee (or the bankruptcy trustee or debtor-in-
possession) is in compliance with the provisions of such agreement under Section
1110 of the Bankruptcy Code or of the Lease as so assumed, as the case may be,
in all respects. For purposes of this Section 4.04(a), the term "Section 1110
Period" means the longer of (1) the 60-day period from the date of the order for
relief under Chapter 11 of the Bankruptcy Code (or such longer period as then
may be in effect under Section 1110 of the Bankruptcy Code, including for this
purpose any extension of such period by the Indenture Trustee (as assignee of
the Owner Trustee) and the bankruptcy trustee or debtor-in-possession pursuant
to Section 1110(b) thereof) and (2) the period during which the applicability of
said Section 1110 to the Aircraft is being contested in good faith by the Lessee
(or the bankruptcy trustee or debtor-in-possession) in judicial proceedings.

          (b) If an Indenture Event of Default referred to in clause (g) or (h)
of Section 4.02 shall have occurred, then and in every such case the unpaid
principal of all Equipment Notes then outstanding, together with interest
accrued but unpaid thereon, and all other amounts due to the holders of the
Equipment Notes thereunder (but not including any amounts in respect of Make-
Whole Amount), hereunder and under the other Operative Agreements, shall, unless
the Indenture Trustee acting upon the instructions of the Majority in Interest
of Noteholders shall otherwise direct, immediately and without further act
become due and payable, without presentment, demand, protest or notice, all of
which are hereby waived.

                                      28
<PAGE>

          (c) If any other Indenture Event of Default shall have occurred and be
continuing, then and in every such case, the Indenture Trustee may at any time,
by written notice or notices to the Owner Trustee, declare all the Equipment
Notes to be due and payable, whereupon the unpaid principal of all Equipment
Notes then outstanding, together with accrued but unpaid interest thereon, and
all other amounts due to the holders of the Equipment Notes thereunder (but not
including any amounts in respect of Make-Whole Amount), hereunder and under the
other Operative Agreements, shall immediately and without further act become due
and payable without presentment, demand, protest or other notice, all of which
are hereby waived.

          (d) Each Noteholder shall be entitled, at any sale pursuant to Section
17(b) of the Lease or this Article IV, to credit against any purchase price bid
at such sale by such Noteholder all or any part of the unpaid obligations owing
to such Noteholder and secured by the Lien of this Indenture. The Indenture
Trustee and the Noteholders shall, upon any such purchase, acquire good title to
the property so purchased, to the extent permitted by applicable law, free of
all rights of redemption.

          SECTION 4.05. Return of Aircraft, etc. (a) If an Indenture Event of
                        ------------------------
Default shall have occurred and be continuing, subject to Section 4.03 and
Section 4.04(a), at the request of the Indenture Trustee the Owner Trustee
shall promptly execute and deliver to the Indenture Trustee such instruments of
title and other documents as the Indenture Trustee may deem necessary or
advisable to enable the Indenture Trustee or an agent or representative
designated by the Indenture Trustee, at such time or times and place or places
as the Indenture Trustee may specify, to obtain possession of all or any part of
the Indenture Estate to which the Indenture Trustee shall at the time be
entitled hereunder. If the Owner Trustee shall for any reason fail to execute
and deliver such instruments and documents after such request by the Indenture
Trustee, the Indenture Trustee may (i) obtain a judgment conferring on the
Indenture Trustee the right to immediate possession and requiring the Owner
Trustee to execute and deliver such instruments and documents to the Indenture
Trustee, to the entry of which judgment the Owner Trustee hereby specifically
consents, and (ii) pursue all or part of the Indenture Estate wherever such
Indenture Estate may be found and may enter any of the premises of the Lessee
wherever it may be or be supposed to be and search for and take possession of
and remove the same. All expenses of obtaining such judgment or of pursuing,
searching for and taking such property shall, until paid, be secured by the Lien
of this Indenture.

          (b) Upon every such taking of possession and during the continuance of
an Indenture Event of Default, the Indenture Trustee may, from time to time, at
the expense of the Indenture Estate, make all such reasonable expenditures for
maintenance, insurance, repairs, replacements, alterations, additions and
improvements to and of the Indenture Estate, as it may deem proper. In each such
case, the Indenture Trustee shall have the right to maintain, use, operate,
store, lease, control or manage the Indenture Estate and to carry on the
business and, without limiting the express provisions of Section 5.09, to
exercise all rights and powers of the Owner Participant and the Owner Trustee
relating to the Indenture Estate, as the Indenture Trustee shall deem best,
including the right to enter into any and all such agreements with respect to
the maintenance, insurance, use, operation, storage, leasing, control,
management or disposition of the Indenture

                                      29
<PAGE>

Estate or any part thereof as the Indenture Trustee may determine; and except
for Excluded Payments, the Indenture Trustee shall be entitled to collect and
receive directly all tolls, rents (including Rent), revenues, issues, income,
products and profits of the Indenture Estate and every part thereof. Such tolls,
rents (including Rent), revenues, issues, income, products and profits shall be
applied to pay the reasonable expenses of the use, operation, storage, leasing,
control, management or disposition of the Indenture Estate and of conducting the
business thereof, and of all maintenance, repairs, replacements, alterations,
additions and improvements, and to make all payments which the Indenture Trustee
may be required or may elect to make, if any, for taxes, assessments, insurance
or other proper charges upon the Indenture Estate or any part thereof (including
the employment of engineers and accountants to examine, inspect and make reports
upon the properties and books and records of the Owner Trustee), and all other
payments which the Indenture Trustee may be required or authorized to make under
any provision of this Indenture, as well as just and reasonable compensation for
the services of the Indenture Trustee, and of all persons properly engaged and
employed by the Indenture Trustee.

          SECTION 4.06.  Remedies Cumulative. Subject to Sections 4.03, 4.04(a),
                         -------------------
4.08 and 5.09, each and every right, power and remedy given to the Indenture
Trustee specifically or otherwise in this Indenture shall be cumulative and
shall be in addition to every other right, power and remedy herein specifically
given or now or hereafter existing at law, in equity or by statute, and each and
every right, power and remedy whether specifically herein given or otherwise
existing may be exercised from time to time and as often and in such order as
may be deemed expedient by the Indenture Trustee, and the exercise or the
beginning of the exercise of any power or remedy shall not be construed to be a
waiver of the right to exercise at the same time or thereafter any other right,
power or remedy. No delay or omission by the Indenture Trustee in the exercise
of any right, remedy or power or in the pursuit of any remedy shall impair any
such right, power or remedy or be construed to be a waiver of any default on the
part of the Owner Trustee or the Lessee or to be an acquiescence therein.

          SECTION 4.07.  Discontinuance of Proceedings. In case the Indenture
                         -----------------------------
Trustee shall have instituted any proceeding to enforce any right, power or
remedy under this Indenture by foreclosure, entry or otherwise, and such
proceedings shall have been discontinued or abandoned for any reason or shall
have been determined adversely to the Indenture Trustee, then and in every such
case the Owner Trustee, the Indenture Trustee and the Lessee shall, subject to
any determination in such proceedings, be restored to their former positions and
rights hereunder with respect to the Indenture Estate, and all rights, remedies
and powers of the Indenture Trustee shall continue as if no such proceedings had
been instituted.

          SECTION 4.08.  Waiver of Past Defaults. Upon written instructions from
                         -----------------------
a Majority in Interest of Noteholders, the Indenture Trustee shall waive any
past Indenture Default or Indenture Event of Default hereunder and its
consequences and upon any such waiver such Default shall cease to exist and any
Indenture Event of Default arising therefrom shall be deemed to have been cured
for every purpose of this Indenture, but no such waiver shall extend to any
subsequent or other Indenture Default or Indenture Event of Default or impair
any right consequent thereon;

                                      30
<PAGE>

provided, however, that in the absence of written instructions from all
- --------  -------
Noteholders, the Indenture Trustee shall not waive any Indenture Default (i) in
the payment of the principal of, or interest on, or other amounts due under, any
Equipment Note then outstanding, or (ii) in respect of a covenant or provision
hereof which, under the proviso to the first sentence of Section 8.01 or under
the last sentence of Section 8.01, cannot be waived without the consent of each
Noteholder.

                                   ARTICLE V

                        DUTIES OF THE INDENTURE TRUSTEE

          SECTION 5.01.  Notices.  (a) Notice of Indenture Event of Default. In
                         -------       ------------------------------------
the event a Responsible Officer of the Indenture Trustee shall have actual
knowledge of an Indenture Event of Default or of an Indenture Default arising
from a failure to pay Basic Rent, the Indenture Trustee shall forthwith give
prompt written notice by telex or facsimile thereof to the Owner Trustee, the
Owner Participant, the Lessee and the Noteholders. Subject to the terms of
Sections 4.03, 4.04(a), 4.08, 5.03 and 5.09, the Indenture Trustee shall take
such action, or refrain from taking such action, with respect to any such
Indenture Event of Default (including with respect to the exercise of any rights
or remedies hereunder) as the Indenture Trustee shall be instructed in writing
by the Majority in Interest of Noteholders. Subject to the provisions of
Sections 4.03, 4.04(a), 4.08, 5.03 and 5.09, if the Indenture Trustee shall not
have received instructions as above provided within twenty (20) calendar days
after receipt of notice of such Indenture Event of Default by the Noteholders,
the Indenture Trustee may, subject to instructions thereafter received pursuant
to the preceding provisions of this Section 5.01, take such action, or refrain
from taking such action, but shall be under no duty to take or refrain from
taking any action, with respect to any such Indenture Event of Default as it
shall determine advisable in the best interests of the Noteholders and shall use
the same degree of care and skill in connection therewith as a prudent person
would use under the circumstances in the conduct of such person's own affairs;
provided that the Indenture Trustee may not sell the Airframe or any Engine
- --------
without the consent of the Majority in Interest of Noteholders. In the event the
Indenture Trustee shall at any time commence to foreclose or otherwise enforce
this Indenture, the Indenture Trustee shall forthwith notify the Noteholders,
the Owner Trustee, the Owner Participant and the Lessee. For all purposes of
this Indenture, in the absence of actual knowledge on the part of a Responsible
Officer in its Corporate Trust Department, in the case of the Indenture Trustee,
or its Corporate Trust Administration, in the case of the Owner Trustee, the
Indenture Trustee or the Owner Trustee, as the case may be, shall not be deemed
to have knowledge of any Indenture Default, any Default or any Event of Default
(except, in the case of the Indenture Trustee, the failure of the Lessee to pay
any installment of Basic Rent when due, which failure shall constitute knowledge
of an Indenture Default) unless notified in writing by the Lessee, the Owner
Trustee or one or more Noteholders. This Section 5.01, however, is subject to
the condition that, if at any time after the principal of the Equipment Notes
shall have become due and payable pursuant to Section 4.04(b) or (c) and before
any judgment or decree for the payment of the money so due, or any thereof,
shall be entered, all overdue payments of interest upon the Equipment Notes and
all other amounts payable under the Equipment Notes (except the principal of the
Equipment Notes which by such declaration shall have become payable) shall have
been duly paid, and every other

                                      31
<PAGE>

Indenture Default and Indenture Event of Default with respect to any covenant or
provision of this Indenture shall have been cured, then and in every such case a
Majority in Interest of Noteholders may (but shall not be obligated to), by
written instrument filed with the Indenture Trustee, rescind and annul such
acceleration and its consequences; but no such rescission or annulment shall
extend to or affect any subsequent Indenture Default or Indenture Event of
Default or impair any right consequent thereon.

          (b) Other Notices.  The Indenture Trustee will furnish to each
              -------------
Noteholder promptly upon receipt thereof, duplicates or copies of all reports,
notices, requests, demands, certificates, financial statements and other
instruments furnished to the Indenture Trustee under any Operative Agreement or
received from the Owner Trustee pursuant to Section 4.01(b) to the extent the
same shall not have been otherwise directly distributed to the Noteholders
pursuant to the express provision of any other Operative Agreement.

          SECTION 5.02.  Action Upon Instructions.  (a) Subject to the terms of

Sections 4.03, 4.04(a), 4.08, 5.01, 5.03 and 5.09, upon the written instructions
at any time and from time to time of a Majority in Interest of Noteholders, the
Indenture Trustee shall take such of the following actions as may be specified
in such instructions: (i) exercise such election or option, or make such
decision or determination, or give such notice, consent, waiver or approval or
exercise such right, remedy or power or take such other action hereunder or
under any other Operative Agreement or in respect of any part or all of the
Indenture Estate as shall be specified in such instructions; (ii) take such
action with respect to, or to preserve or protect, the Indenture Estate
(including the discharge of Liens) as shall be specified in such instructions
and as is consistent with this Indenture; and (iii) take such other action in
respect of the subject matter of this Indenture as is consistent with the terms
hereof and the other Indenture Documents. The Indenture Trustee will execute and
the Owner Trustee will file or cause to be filed such continuation statements
with respect to financing statements relating to the security interests created
hereunder in the Indenture Estate as may be specified from time to time in
written instructions of a Majority in Interest of Noteholders or Lessee (which
instructions may, by their terms, be operative only at a future date and which
shall be accompanied by the execution form of such continuation statement so to
be filed).

          (b) Subject to Sections 4.03, 4.04(a), 4.08, 5.01, 5.03 and 5.09, if
any Event of Default shall have occurred and be continuing, on request of a
Majority in Interest of Noteholders, the Indenture Trustee shall declare the
Lease to be in default and exercise such remedies under Section 17 of the Lease
as shall be specified in such request. The Indenture Trustee agrees to provide
to the Noteholders, the Owner Trustee and the Owner Participant concurrently
with such declaration by the Indenture Trustee, notice of such declaration by
the Indenture Trustee; provided that the failure to give any such notice to such
                       --------
Noteholders, the Owner Trustee or the Owner Participant shall not affect the
validity of such declaration.

          SECTION 5.03.  Indemnification.  The Indenture Trustee shall not be
                         ---------------
required to take any action or refrain from taking any action under Section 5.01

<PAGE>

Noteholders against any liability, cost or expense (including reasonable counsel
fees) which may be incurred in connection therewith (except for the consequences
of the Indenture Trustee's gross negligence, willful misconduct and, in
receiving, handling or remitting funds only, its failure to use ordinary care).
The Indenture Trustee shall not be under any obligation to take any action under
this Indenture and nothing contained in this Indenture shall require the
Indenture Trustee to expend or risk its own funds or otherwise incur any
financial liability in the performance of any of its duties hereunder or in the
exercise of any of its rights or powers if it shall have reasonable grounds for
believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it on the terms provided above. The
Indenture Trustee shall not be required to take any action under Section 5.01
(other than the first sentence thereof) or 5.02 or Article IV, nor shall any
other provision of this Indenture be deemed to impose a duty on the Indenture
Trustee to take any action, if the Indenture Trustee shall have been advised by
counsel that such action is contrary to the terms hereof or is otherwise
contrary to law.

          SECTION 5.04.  No Duties Except as Specified in Indenture or
                         ---------------------------------------------

Indenture or any part of the Indenture Estate, except as expressly provided by
the terms of this Indenture or as expressly provided in written instructions
from the Noteholders as provided in this Indenture; and no implied duties or
obligations shall be read into this Indenture against the Indenture Trustee. The
Indenture Trustee agrees that it will, in its individual capacity and at its own
cost and expense promptly take such action as may be necessary to duly discharge
all Liens on any part of the Indenture Estate which result from claims against
it in its individual capacity not related to the mortgaging to it of the
Aircraft or the administration of the Indenture Estate or any other transaction
contemplated by or pursuant to the Participation Agreement or any document
included in the Indenture Estate.

          SECTION 5.05.  No Action Except Under Lease, Participation Agreement,

Agreement, or (ii) in accordance with the powers granted or reserved to, or the
authority conferred upon, the Owner Trustee and the Indenture Trustee pursuant
to this Indenture and in accordance with the express terms hereof. Any breach of
this covenant resulting solely from an Event of Default shall not be an
Indenture Event of Default other than pursuant to Section 4.02(a).

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

          Indenture and the Lease and, upon the basis of such application, the

Notwithstanding any other provision of this Indenture, including the Granting
Clause, or of any other Operative Agreement, the following rights shall be
reserved to the Owner Trustee or the Owner Participant, as the case may be, to
the extent described herein:

               (a) to the exclusion of the Indenture Trustee, so long as no

                        --------  -------
     and (2)(B) of this Section 5.09(e) shall not affect the right of the
     Indenture Trustee to approve or consent to any matter or accept any
     modified performance under the Lease without the consent of the Owner
     Trustee or the Owner Participant, so long as such consent, approval or
     acceptance does not purport to bind the Owner Trustee vis-a-vis the Lessee
     or purport to constitute, as between the Owner Trustee and the Lessee, a
     waiver of the rights of the Owner Trustee under the Lease or an amendment
     or modification of the obligations of the Lessee under the Lease;

               (f) the Owner Trustee shall have the non-exclusive right, as
     Lessor, to seek specific performance of the covenants of the Lessee under
     the Lease relating to the protection, insurance, maintenance, possession

     of Default shall have occurred and be continuing, the right, together with
     the Indenture Trustee, to exercise all other rights, powers, privileges and
     remedies under any Indenture Document (other than the Lease (other than
     relating to Excluded Payments)) or consent to or approve any other matter
     referred to in any Indenture Document (other than the Lease (other than
     relating to Excluded Payments)) as requiring or being subject to the
     consent or approval of the Owner Trustee.

Upon consummation of a foreclosure of the Lien and security interest of the
Indenture on the Indenture Estate, all rights of the Owner Trustee or the Owner
Participant (as the case may be) under this Section 5.09 shall terminate, except
insofar as such rights relate to Excluded Payments. Notwithstanding the
foregoing, and subject to the provisions of Sections 4.03 and 4.04(a), the
Indenture Trustee shall at all times have the right, to the exclusion of the
Owner Trustee and the Owner Participant to exercise the remedies set forth in
Section 17 of the Lease (other than in connection with Excluded Payments) and in
Article IV hereof.

          SECTION 6.04.  No Segregation of Monies; No Interest. Any monies paid
                         -------------------------------------
to or retained by the Indenture Trustee pursuant to any provision hereof and not
then required to be distributed to any Noteholder, the Lessee or the Owner
Trustee as provided in Article III need not be segregated in any manner except
to the extent required by law, and may be deposited under such general
conditions as may be prescribed by law, and the Indenture Trustee shall not
(except as otherwise provided in Section 3.07) be liable for any interest
thereon; provided that any payments received or applied hereunder by the
         --------
Indenture Trustee shall be accounted for by the Indenture Trustee so that any
portion thereof paid or applied pursuant hereto shall be identifiable as to the
source thereof.

          SECTION 6.05.  Reliance; Agents; Advice of Counsel. Neither the Owner
                         -----------------------------------
Trustee nor the Indenture Trustee shall incur liability to anyone in acting upon
any signature, instrument, notice, resolution, request, consent, order,
certificate, report, opinion, bond or other document or paper believed by it to
be genuine and believed by it to be signed by the proper party or parties. The
Owner Trustee and the Indenture Trustee may accept a copy of a resolution of the
Board of Directors of any party to the Participation Agreement, certified by the
Secretary or an Assistant Secretary or other Responsible Officer thereof as duly
adopted and in full force and effect, as conclusive evidence that such
resolution has been duly adopted and that the same is in full force and effect.
As to the aggregate unpaid principal amount of Equipment Notes outstanding as of
any date, the Owner Trustee may for all purposes hereof rely on a certificate
signed by any Vice President or other authorized corporate trust officer of the
Indenture Trustee. As to any fact or matter relating to the Lessee the manner of
ascertainment of which is not specifically described herein, the Owner Trustee
and the Indenture Trustee may for all purposes hereof rely on a certificate,
signed by a duly authorized officer of the Lessee, as to such fact or matter,
and such certificate shall constitute full protection to the Owner Trustee and
the Indenture Trustee for any action taken or omitted to be taken by them in
good faith in reliance thereon. The Indenture Trustee shall assume, and shall be
fully protected in assuming, that the Owner Trustee is authorized by the Trust
Agreement to enter into this Indenture and to take all action to be taken by it
pursuant to the provisions hereof, and shall not inquire into the authorization
of the Owner Trustee with respect thereto. In the administration of the trusts
hereunder, the Owner Trustee and the Indenture Trustee each may execute any of
the trusts or powers hereof and perform its powers and duties hereunder directly
or through agents or attorneys and may, at the expense of the Indenture Estate,
advise with counsel, accountants and other skilled persons to be selected and
retained by it, and the Owner Trustee and the Indenture Trustee shall not

                                      40
<PAGE>

be liable for anything done, suffered or omitted in good faith by them in
accordance with the written advice or written opinion of any such counsel,
accountants or other skilled persons.

          SECTION 6.06.  Capacity in Which Acting. Each of the Owner Trustee and
                         ------------------------
the Indenture Trustee acts hereunder solely as trustee herein, and, in the case
of the Owner Trustee, as provided in the Trust Agreement, and not in its
individual capacity, except as otherwise expressly provided in the Operative
Agreements.

          SECTION 6.07.  Compensation. The Indenture Trustee shall be entitled
                         ------------
to reasonable compensation, including expenses and disbursements, for all
services rendered hereunder and shall have a priority claim on the Indenture
Estate for the payment of such compensation, to the extent that such
compensation shall not be paid by the Lessee or others, as required under the
Indenture Documents, and shall have the right to use or apply any monies held by
it hereunder in the Indenture Estate toward such payments. The Indenture Trustee
agrees that it shall have no right against the Noteholders or (except as
provided in the Participation Agreement) the Owner Participant for any fee as
compensation for its services as trustee under this Indenture.

          SECTION 6.08.  May Become Noteholder. Each of the institutions acting
                         ---------------------
as Owner Trustee and Indenture Trustee hereunder may become a Noteholder and
have all rights and benefits of a Noteholder to the same extent as if it were
not the institution acting as Owner Trustee or Indenture Trustee, as the case
may be.

          SECTION 6.09.  Further Assurances; Financing Statements. At any time
                         ----------------------------------------
and from time to time, upon the request of the Indenture Trustee, the Owner
Trustee shall promptly and duly execute and deliver any and all such further
instruments and documents as may be specified in such request and as are
necessary or desirable to perfect, preserve or protect the mortgage, security
interests and assignments created or intended to be created hereby, or to obtain
for the Indenture Trustee the full benefit of the specific rights and powers
herein granted, including, without limitation, the execution and delivery of
Uniform Commercial Code financing statements and continuation statements with
respect thereto, or similar instruments relating to the perfection of the
mortgage, security interests or assignments created or intended to be created
hereby.

          SECTION 6.10.  Assumption of Equipment Notes upon Purchase of
                         ----------------------------------------------
Aircraft. In the event that the Lessee elects to purchase the Aircraft pursuant
- --------
to Section 13(b)(ii) of the Lease and in connection therewith shall exercise its
right under Section 5.10 of the Participation Agreement to make such purchase,
in part, by assuming the obligations of the Owner Trustee under the Equipment
Notes, then upon satisfaction of all of the requirements of Section 5.10 of the
Participation Agreement (including the amendment of this Indenture), the rights
and obligations of the Owner Trustee under this Indenture shall be assumed by
the Lessee and, as of the time of such assumption, the Owner Trustee shall be
discharged therefrom (without affecting any liability of the Owner Trustee or
the Trust Company in respect of any obligation of the Owner Trustee or the Trust
Company arising out of or relating to the time before such assumption).

                     SUCCESSOR TRUSTEES; SEPARATE TRUSTEES

          SECTION 7.01.  Notice of Successor Owner Trustee.  In the case of any
                         ---------------------------------
appointment of a successor to the Owner Trustee pursuant to the Trust Agreement
or any merger, conversion, consolidation or sale of substantially all of the
corporate trust business of the Owner Trustee pursuant to the Trust Agreement,
the successor Owner Trustee shall give prompt written notice thereof to the
Indenture Trustee and to each Noteholder.

          SECTION 7.02.  Resignation of Indenture Trustee; Appointment of
                         ------------------------------------------------
Successor. (a) The Indenture Trustee or any successor thereto may resign at any
- ---------
time without cause by giving at least thirty (30) calendar days, prior written
notice to the Owner Participant, the Lessee, the Owner Trustee and each
Noteholder, such resignation to be effective upon the acceptance of the
trusteeship by a successor Indenture Trustee. In addition, a Majority in
Interest of Noteholders may at any time remove the Indenture Trustee without
cause by an instrument in writing delivered to the Owner Participant, the Owner
Trustee, the Lessee and the Indenture Trustee, and the Owner Trustee shall
promptly notify each Noteholder thereof in writing, such removal to be effective
upon the acceptance of the trusteeship by a successor Indenture Trustee. In the
case of the resignation or removal of the Indenture Trustee, a majority in
Interest of Noteholders may appoint a successor Indenture Trustee by an
instrument signed by such Noteholders. If a successor Indenture Trustee shall
not have been appointed within thirty (30) calendar days after such notice of
resignation or removal, the Indenture Trustee, the Owner Trustee or any
Noteholder may apply to any court of competent jurisdiction to appoint a
successor Indenture Trustee to act until such time, if any, as a successor shall
have been appointed as above provided. The successor Indenture Trustee so
appointed by such court shall immediately and without further act be superseded
by any successor Indenture Trustee appointed as above provided within one year
from the date of the appointment by such court.

          (b) Any successor Indenture Trustee, however appointed, shall execute
and deliver to the Owner Trustee and to the predecessor Indenture Trustee an
instrument accepting such appointment, and thereupon such successor Indenture
Trustee, without further act, shall become vested with all the estates,
properties, rights, powers and duties of the predecessor Indenture Trustee
hereunder in the trusts hereunder applicable to it with like effect as if
originally named the Indenture Trustee herein; provided that the rights of the
                                               --------
predecessor Indenture Trustee to any compensation or indemnity relating to the
period prior to such transfer shall survive such transfer and the predecessor
Indenture Trustee shall retain any Lien which it may have on the Indenture
Estate securing such amounts; but nevertheless upon the written request of such
successor Indenture Trustee, such predecessor Indenture Trustee shall execute
and deliver an instrument transferring to such successor Indenture Trustee, upon
the trusts herein expressed applicable to it, all the estates, properties,
rights and powers of such predecessor Indenture Trustee, and such predecessor
Indenture Trustee shall duly assign, transfer, deliver and pay over to such
successor Indenture Trustee all monies or other property then held by such
predecessor Indenture Trustee hereunder, provided that such predecessor
                                         --------
Indenture Trustee shall be entitled to deduct from any monies held by it

                                      42
<PAGE>

constituting part of the Indenture Estate all compensation and indemnity then
due to it. Upon the successor Indenture Trustee accepting such appointment, the
predecessor Indenture Trustee shall be relieved of any further obligation and
liability hereunder and under the other Operative Agreements arising after the
time of such transfer.

          (c) Any successor Indenture Trustee, however appointed, shall be a
Citizen of the United States and shall also be a bank or trust company having a
combined capital and surplus of at least $100,000,000, if there be such an
institution willing, able and legally qualified to perform the duties of the
Indenture Trustee hereunder upon reasonable or customary terms.

          (d) Any corporation into which the Indenture Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Indenture Trustee
shall be a party, or any corporation to which substantially all the corporate
trust business of the Indenture Trustee (including this account) may be
transferred, shall, subject to the terms of paragraph (c) of this Section, be
the Indenture Trustee under this Indenture without further act.

          SECTION 7.03.  Appointment of Separate Trustees. (a) At any time or
                         --------------------------------
times, for the purpose of meeting any legal requirements of any jurisdiction in
which any part of the Indenture Estate may at the time be located or in which
any action of the Indenture Trustee may be required to be performed or taken or
if the Indenture Trustee shall be advised by counsel satisfactory to it that it
is so necessary or prudent in the interests of the Noteholders, or in the event
the Indenture Trustee shall have been requested to do so by a Majority in
Interest of Noteholders, the Indenture Trustee, by an instrument in writing
signed by it, and without the concurrence of the Owner Trustee, may appoint one
or more individuals or corporations to act as separate trustee or separate
trustees or co-trustee, acting jointly with the Indenture Trustee, or to act as
separate trustee or trustees of all or any part of the Indenture Estate with
such powers as may be provided in an agreement supplemental hereto.

          (b) The Indenture Trustee and, at the request of the Indenture
Trustee, the Owner Trustee, shall execute, acknowledge and deliver all such
instruments as may be required by the legal requirements of any jurisdiction or
by any such separate trustee or separate trustees or co-trustee for the purpose
of more fully confirming such title, rights or duties to such separate trustee
or separate trustees or co-trustee and the Owner Trustee hereby makes,
constitutes and appoints the Indenture Trustee its agent and attorney- in- fact
for it and in its name, place and stead to execute, acknowledge and deliver the
same in the event that the Owner Trustee shall not itself execute and deliver
the same within twenty days after receipt by it of such request so to do. Upon
the acceptance in writing of such appointment by any such separate trustee or
separate trustees or co-trustee, it or they shall be vested with such title to
the Indenture Estate or any part thereof, and with such rights and duties, as
shall be specified in the instrument of appointment, jointly with the Indenture
Trustee (except insofar as local law makes it necessary for any such separate
trustee or separate trustees or co-trustee to act alone) subject to all the
terms of this Indenture. Any separate trustee or separate trustees or co-trustee
may, at any time by an instrument in writing, constitute the Indenture Trustee
its attorney-in-fact and

                                      43
<PAGE>

agent with full power and authority to do all acts and things and to exercise
all discretion on its behalf and in its name. In case any such separate trustee
or co-trustee shall die, become incapable of acting, resign or be removed, the
title to the Indenture Estate and all assets, property, rights, powers, trusts,
obligations and duties of such separate trustee or co-trustee shall, so far as
permitted by law, vest in and be exercised by the Indenture Trustee, without the
appointment of a successor to such separate trustee or co-trustee unless and
until a successor is appointed.

          (c) All provisions of this Indenture which are for the benefit of the
Indenture Trustee shall extend to and apply to each separate trustee or
co-trustee appointed pursuant to the foregoing provisions of this Section 7.03.

          (d) Every separate trustee and co-trustee hereunder shall, to the
extent permitted by law, be appointed and act and the Indenture Trustee shall
act, subject to the following provisions and conditions:

              (i)   all powers, duties, obligations and rights conferred upon
          the Indenture Trustee in respect of the receipt, custody, investment
          and payment of monies shall be exercised solely by the Indenture
          Trustee;

              (ii)  all other rights, powers, duties and obligations conferred
          or imposed upon the Indenture Trustee shall be conferred or imposed
          upon and exercised or performed by the Indenture Trustee and such
          separate trustee or separate trustees or co-trustee jointly except to
          the extent that under any law of any jurisdiction in which any
          particular act or acts are to be performed, the Indenture Trustee
          shall be incompetent or unqualified to perform such act or acts, in
          which event such rights, powers, duties and obligations (including the
          holding of title to the Indenture Estate in any such jurisdiction)
          shall be exercised and performed by such separate trustee or separate
          trustees or co-trustee;

              (iii) no power hereby given to, or with respect to which it is
          hereby provided may be exercised by, any such separate trustee or
          separate trustees or co-trustee shall be exercised hereunder by such
          Person except jointly with, or with the consent of, the Indenture
          Trustee; and

              (iv)  no trustee hereunder shall be personally liable by reason of
          any act or omission of any other trustee hereunder.

If at any time the Indenture Trustee shall deem it no longer necessary or
prudent in order to conform to any such law, or take any such action or shall be
advised by such counsel that it is no longer legally required or necessary or
prudent in the interest of the Noteholders or in the event the Indenture Trustee
shall have been requested to do so by a Majority in Interest of Noteholders, the
Indenture Trustee shall execute and deliver an indenture supplement hereto and
all other instruments and agreements necessary or proper to remove any separate
trustee or separate trustees or co-trustee.

                                      44
<PAGE>

          (e) Any request, approval or consent in writing by the Indenture
Trustee to any separate trustee or separate trustees or co-trustee shall be
sufficient warrant to such separate trustee or separate trustees or co-trustee,
as the case may be, to take such action as may be so requested, approved or
consented to.

          (f) Notwithstanding any other provision of this Section 7.03, the
powers of any separate trustee or separate trustees or co-trustee appointed
pursuant to this Section 7.03 shall not in any case exceed those of the
Indenture Trustee hereunder.

connection with a re-lease or sale of the Aircraft, the Airframe or any Engine.
Any such determination pursuant to Section 17 of the Lease shall be made by a
recognized independent aircraft appraiser selected by Lessor and the costs and
expenses associated therewith shall be borne by Lessee, unless Lessor does not
obtain possession of the Aircraft, Airframe and Engines pursuant to Section 17

Rental Value and Fair Market Sales Value for purposes of Section 17 of the Lease

Section 2.     Delivery and Leasing of the Aircraft.
               ------------------------------------

               (a)  Leasing of the Aircraft.
                    -----------------------

               Subject to the satisfaction or waiver of the conditions precedent
stated in the Participation Agreement, the Lessor agrees to lease to the Lessee,

Section 3.     Term and Rent.
               -------------

               (a)  Term.
                    ----

               The Aircraft is leased for a Term which shall comprise the Basic
Term and, at the option of the Lessee exercised in accordance with Section
13(a), one or more Renewal Terms. The Basic Term shall commence on the Delivery
Date and continue through the Expiration Date; and each Renewal Term, if any,
shall be for the applicable period provided in Section 13(a), except that the
Term (including the Basic Term or any Renewal Term, as the case may be) shall
end upon any earlier termination of this Lease according to its terms.

               (b)  Basic Rent.
                    ----------

               The Lessee shall pay Basic Rent in consecutive semi-annual
installments on each Basic Rent Payment Date during the Basic Term, each such
installment to be in an amount

                                      -2-
<PAGE>

determined by multiplying Lessor's Cost by the percentage set forth in Exhibit C
for the applicable Basic Rent Payment Date. The Lessee shall pay Basic Rent
during a Renewal Term in the amounts and at the times provided in Section 13(a)
for such Renewal Term.

          (c) Supplemental Rent.
              -----------------

          The Lessee shall pay to the Lessor, or to whoever shall be entitled
thereto, any and all Supplemental Rent when the same shall become due and owing.
Without limiting the foregoing, the Lessee shall pay as Supplemental Rent:

                    (i)   to the Lessor, on demand, interest at the Past Due
               Rate on any part of any installment of Basic Rent not paid when
               due for the period for which the same shall be overdue;

                    (ii)  to whoever shall have been entitled to receive the
               relevant payment of Supplemental Rent, on demand, interest at the
               Past Due Rate on any payment of Supplemental Rent (other than
               interest payable under this clause (ii)) not paid when due for
               the period for which the same shall be overdue;

                    (iii) to the Lessor, an amount equal to any Make-Whole
               Amount as and when such amount is due and payable by the Lessor
               under the terms of the Indenture (except in the case of any
               prepayment pursuant to Section 2.12 of the Indenture); and

                    (iv)  to the Lessor, an amount equal to any Increased Cost
               or other amount that the Lessor is obligated to pay pursuant to
               Section 2.14 of the Indenture.

          The obligations of the Lessee to pay Supplemental Rent provided for in
this Section 3(c) shall survive the expiration or other termination of this
Lease.

          (d) Adjustments to Basic Rent and Termination Values.
              ------------------------------------------------

          All installments of Basic Rent remaining to be paid during the Basic
Term shall be recalculated and adjusted, upwards or downwards as the case may be
(and corresponding adjustments shall be made to the EBO Amount and the
Termination Values applicable during the remaining Basic Term) to maintain the
Net Economic Return and, to the greatest extent consistent with such maintenance
of such Net Economic Return, to minimize the net present value (calculated at a
discount rate equal to the Applicable Rate or such other rate as may be
specified by the Lessee to the Owner Participant) of the remaining Basic Rent
payments (or, if the Lessee shall have so

                                      -3-
<PAGE>

specified to the Owner Participant, the remaining Basic Rent Payments to the EBO
Date together with the EBO Amount), if:

          (i)   the Delivery Date shall not be August 16, 1999;

          (ii)  there shall be a refinancing or refunding of the debt evidenced
     by the Equipment Notes pursuant to Section 13.01 of the Participation
     Agreement;

          (iii) the Transaction Costs payable by the Owner Participant pursuant
     to Section 8.01(a) of the Participation Agreement shall be greater or less
     than the percentage of Lessor's Cost set forth on Exhibit B; or

          (iv)  there shall be an adjustment of Termination Values as provided
     in Section 16 of the Tax Indemnity Agreement.

Adjustments to the installments of Basic Rent (expressed as percentages of
Lessor's Cost) set forth in Exhibit C and conforming adjustments to the EBO
Amount and the amounts of Termination Values (expressed as percentages of
Lessor's Cost) set forth in Exhibit D shall be calculated by the Owner
Participant in accordance with the terms of this Section 3(d), and the Owner
Participant shall deliver to the Lessee, the Lessor and the Indenture Trustee
schedules setting forth the revised EBO Amount and the revised percentages that
the Owner Participant proposes to include in Exhibits C and D, subject to review
by the Lessee and verification as provided herein.  In the event of a dispute
regarding any such adjustment which is not resolved by agreement of the Lessee
and the Owner Participant, the adjustments, at the request of the Lessee
delivered to the Owner Participant within 30 days after receipt of the Owner
Participant's proposed adjustments, shall be subjected to verification by a
lease advisory firm or a nationally recognized firm of accountants to be
selected by the Owner Participant and reasonably acceptable to the Lessee.  The
Owner Participant shall provide to such firm, but not, in any circumstances, to
Lessee or any representatives of Lessee, on a confidential basis such
information as such firm may reasonably require, including, without limitation,
a true copy of this Lease and a full description of the methodology and
assumptions employed by the Owner Participant in calculating the EBO Amount or
Basic Rent or Termination Value set forth in Exhibits C and D as in effect on
the Delivery Date and a true copy of the calculations of the same performed by
the Owner Participant at the time, to enable such firm to determine whether the
adjustments proposed by the Owner Participant are mathematically accurate, apply
the same methodology and assumptions (except to the extent changed by the events
giving rise to such recalculation) as were employed in the calculations of the
Basic Rent, EBO Amount and Termination Values in effect on the Delivery Date,
and are otherwise in conformity with the provisions of this Lease.  The Lessee
and its financial advisors shall be entitled to submit such data and views as
the Lessee may elect to such firm concerning the proposed adjustments.  The firm
shall be requested to deliver to each of the Owner Participant, the Lessee, the
Lessor and the Indenture Trustee within 30 days after its appointment its
determination as to the changes, if any, that are appropriate with respect to
the adjustments proposed by the Owner Participant.  The adjustments

                                      -4-
<PAGE>

proposed by the Owner Participant, if not disputed by the Lessee as provided
above, or the determination of the firm as provided above, as the case may be,
shall be conclusive, final and binding upon the Lessor, the Lessee and the Owner
Participant, and the EBO Amount and Exhibits C and D shall be amended to reflect
them. No dispute concerning any adjustment shall release the Lessee from its
obligation to pay the EBO Amount or Basic Rent or Termination Value as then set
forth in Exhibits C and D. All reasonable fees and expenses payable to a firm
pursuant to this paragraph shall be paid by the Lessee except that such fees and
expenses shall be paid entirely by the Owner Participant if, as a result of
changes determined by the firm, the net present value, discounted at the
Applicable Rate or such other rate as the Lessee may have specified as provided
above in this paragraph, of Basic Rent remaining to be paid is ten basis points
(0.10%) or more lower than it would have been under the adjustments proposed by
the Owner Participant.

Any adjustments made pursuant to this Section 3(d) shall (i) be made so as to
avoid characterization of this Lease as a "disqualified leaseback or long-term
agreement" within the meaning of Section 467 of the Code and/or regulations
thereunder (or any successor or relevant Code provision or regulations) and (ii)
be in compliance with the requirements of Sections 4.02(5) and 4.07(l) of the
Revenue Procedure 75-28 (or any successor relevant procedure), except to the
extent that on the Delivery Date the Lease constituted such a "disqualified
leaseback or long-term agreement" or was not in compliance with the revenue
procedure referred to in clause (ii). In addition, notwithstanding any other
provisions herein, in no event shall the EBO Amount be adjusted to an amount
that is less than the greater of (A) the adjusted Termination Value as of the
applicable EBO Date, (B) the estimated fair market value of the Aircraft on the
applicable EBO Date (as set forth in the appraisal received pursuant to Section
3.01(b)(xiii) of the Participation Agreement), and (C) the present value as of
the applicable EBO Date of (x) the remaining scheduled Basic Rent through the
end of the Basic Term plus (y) Estimated Value (as identified on Exhibit B) (the
present value calculation described in this clause (C) shall utilize a semi-
annual compounded discount rate no lower than the rate per annum identified on
Exhibit B as the Compounded Discount Rate). All adjustments required pursuant to
this Section 3(d) shall be set forth in a Lease Supplement or in an amendment to
this Lease, and promptly after execution thereof by Lessor and Lessee, Lessee
shall give a copy thereof to the Indenture Trustee.

          (e) Manner of Payment.
              -----------------

          All Rent payable by the Lessee to the Lessor hereunder shall be paid
to the Lessor at its principal office at One Rodney Square, 920 King Street,
Suite 102, Wilmington, Delaware, 19801, Attention: Corporate Trust
Administration, or to such other address as the Lessor shall specify in a notice
to the Lessee, in Dollars in immediately available funds, so that the Lessor
receives the full amount of each payment not later than 12:00 noon Eastern Time
on the due date thereof, except that so long as the Indenture shall not have
terminated pursuant to its terms, all Rent payable to the Lessor (other than
Excluded Payments) shall be paid to the Indenture Trustee, in the manner
provided above, at its principal office as specified in Section 12.01 of the
Participation Agreement, or as the Indenture Trustee may otherwise direct by a
notice delivered to the Lessee prior

                                      -5-
<PAGE>

to the date of payment. If any Rent is due on a day that is not a Business Day,
such Rent shall be paid on the next succeeding Business Day with the same force
and effect as if paid on the scheduled date of payment and (if paid on such next
succeeding Business Day) no interest shall accrue on the amount of such payment
from and after such scheduled date to the time of payment on such next
succeeding Business Day. Whether or not the Indenture remains in effect, Rent
constituting Excluded Payments shall be paid directly to the Person entitled
thereto in the manner and at or before the time specified above.

          (f) Minimum Rent.
              ------------

          Anything herein to the contrary notwithstanding,

                    (i)  each installment of Basic Rent, whether or not such
               installment has been adjusted pursuant to Section 3(d), shall be
               in an amount which is at least equal to the amount of any
               principal of and interest on the Equipment Notes that falls due
               and is payable by the Lessor pursuant to the terms of the
               Indenture and the Equipment Notes (other than by reason of
               acceleration of the Equipment Notes) on the date when such
               installment of Basic Rent is due, and

                    (ii) Termination Value and EBO Amount, whether or not
               Termination Value or EBO Amount has been adjusted pursuant to
               Section 3(d), shall be in an amount which (when taken together
               with any Basic Rent due and payable in connection therewith) is
               at least equal to, as of the applicable date of payment, the
               aggregate unpaid principal of and accrued interest on the
               Equipment Notes (other than overdue amounts attributable to an
               Indenture Event of Default not caused solely by an Event of
               Default).

The preceding sentence is intended solely to provide for, and to allocate as
between the Lessor and the Lessee the risk of, the possibility of miscalculation
by the Lessor and the Lessee of amounts of Rent which it is contemplated will be
available to the Indenture Trustee, as the Lessor's security assignee under the
Indenture, for application to the payment of amounts payable by the Lessor on
the Equipment Notes. The Lessee does not guarantee, and nothing in this
paragraph (f) shall be construed to be a guarantee by the Lessee, that the
Lessor will repay any principal of or pay any premium or interest on any
Equipment Notes or that the Indenture Trustee will, or will be able to, apply
for such purposes any amount of Rent paid by the Lessee.

          (g) Rent Obligations Unconditional.
              ------------------------------

          This Lease is a net lease, and it is intended that Lessee shall pay
all costs and expenses of every character, whether seen or unforseen, ordinary
or extraordinary or structural or nonstructural, in connection with the use,
operation, maintenance, repair and reconstruction of the

                                      -6-
<PAGE>

Airframe and the Engines by Lessee, including the costs and expenses
particularly set forth in this Lease. The Lessee's obligations to pay all Rent
due and owing under the terms hereof shall be absolute and unconditional and
shall not be affected by any circumstance whatsoever including, without
limitation, (i) any setoff, counterclaim, recoupment or other right which the
Lessee may have against the Lessor, the Owner Participant, the Indenture
Trustee, the holders of the Equipment Notes or anyone else for any reason
whatsoever, (ii) any defect in the title, airworthiness, condition, design,
operation or fitness for use of, or any damage to or loss or destruction of, the
Aircraft, or any interference, interruption or cessation in or prohibition of
the use or possession thereof by the Lessee for any reason whatsoever,
including, without limitation, any such interference, interruption, cessation or
prohibition resulting from the act of any governmental authority or any
violation by the Lessor of Section 4 hereof, (iii) any Liens, encumbrances or
rights of others with respect to the Aircraft, (iv) the invalidity or
unenforceability or lack of due authorization or other infirmity or
disaffirmance of this Lease or any provision hereof or any other Operative
Agreement or any lack of right, power or authority of the Lessor or the Lessee
to enter into this Lease or any other Operative Agreement, (v) any insolvency,
bankruptcy, reorganization or similar proceedings by or against the Lessee, or
any other Person, or (vi) any other cause whether similar or dissimilar to the
foregoing, any present or future law notwithstanding, it being the intention of
the parties that all Rent payable by the Lessee hereunder shall continue to be
payable in all events in the manner and at the times provided herein. Such Rent
shall not be subject to any abatement and the payments thereof shall not be
subject to any setoff or any reduction for any reason. To the extent permitted
by Applicable Law, the Lessee waives any rights which it may now have or which
may be conferred upon it by statute or otherwise to terminate, cancel, quit or
surrender this Lease except in accordance with the terms hereof. If for any
reason whatsoever this Lease shall be terminated in whole or in part by
operation of law or otherwise except as specifically provided in Sections 8, 13,
14 and 17, Lessee nonetheless agrees to pay to Lessor an amount equal to the
Rent payment at the time such payment would have become due and payable in
accordance with the terms hereof had this Lease not been terminated in whole or
in part. Subject to the following sentence, each payment of Rent made by Lessee
to Lessor shall be final as to Lessor and Lessee and Lessee will not seek to
recover all or any part of such payment of Rent for any reason whatsoever.
Nothing herein shall be construed as a waiver by the Lessee of any claim it may
have against any Person arising under any of the Operative Agreements or
otherwise, including, without limitation, any claim that Rent payments demanded
from or paid by the Lessee are or were not due, are or were erroneous or were
paid under mistake or protest, or be construed as a limitation on any rights of
the Lessee to assert any claim in any proceeding at law, in equity or otherwise
against the Lessor or any other Person and to pursue and obtain relief on such
claim in such manner as the Lessee shall deem appropriate other than by setoff
against Rent payments due under the terms hereof.

Section 4.     The Lessor's Representations and Warranties.

     such government of such use or title (it being understood that in the event
     such opinion cannot be given in a form reasonably satisfactory to the
     Lessor and the Owner Participant, such opinion will be waived if insurance
     reasonably satisfactory to the Lessor and the Owner Participant is provided
     to cover such requisition), (IV) the laws of such sublessee's country of
     domicile would give recognition to Lessor's title to such Engine or the

     registered or qualified, as a result, in whole or in part, of the proposed
     sublease, (VII) the agreement of such Permitted Sublessee that its rights

               Participant is provided to cover the risk of such tort
               liability); provided that no such sublease shall be made to a

               Permitted Sublessee of the type described in clause (b) of

               meaning of Section 168(h) of the Code prior to the end of the
               Recovery Period, unless the Lessee prepays on a lump sum basis
               any liability due under the Tax Indemnity Agreement as a result
               of such sublease based upon the assumption that such sublease
               will continue for the full term of such sublease;

provided that (1) the rights of any transferee who receives possession by reason
- --------
of a transfer permitted by this Section 5(b) (other than by a transfer of an
Engine which is deemed an Event of Loss) shall be subject and subordinate to all
the terms of this Lease; (2) the Lessee shall remain primarily liable hereunder
for the performance of all the terms and conditions of this Lease and all of the
terms and conditions of this Lease and the other applicable Operative Agreements
shall remain in effect; (3) no sublease or transfer of possession otherwise in
compliance with this Section 5(b) shall (A) result in any registration or re-

Section 5(b), provide to Lessor and Owner Participant, forms of the broker's
report and insurance certificates required by Section 9(g); (6) all necessary
documents shall have been duly filed or recorded in applicable public offices
and all other necessary action shall be taken as may be required to preserve the

Participant, Loan Participant and Indenture Trustee, on an After Tax Basis, for

          In the case of any sublease permitted under this Section 5(b), the
Lessee will include in such sublease appropriate provisions which (a) make such
sublease expressly subject and subordinate to all of the terms of this Lease and
the Indenture, including the rights of the Lessor and the Indenture Trustee to
avoid such sublease in the exercise of their rights to repossession of the
Airframe and Engines hereunder and thereunder; (b) expressly prohibit any
further subleasing of the Airframe and Engines; (c) require that the Airframe
and Engines be maintained in accordance with a maintenance program approved by
the Aeronautical Authority applicable thereto; (d) require the sublessee to
comply with the terms of Section 9 hereof; (e) limit the term of such sublease
(including renewal rights) to a period not beyond the end of the Term unless the
Lessee shall then have irrevocably committed to exercise a purchase option in
accordance with the terms hereof; (f) require that the Airframe and Engines be
used in accordance with the limitations applicable to the Lessee's possession
and use provided in this Lease; (g) provide that the Aircraft will not be
operated in any country with which the United States is then conducting ongoing
hostilities; (h) provide that any payments due under such sublease shall be paid
by the Permitted Sublessee directly to the Indenture Trustee (or, if the
Indenture shall have been discharged and satisfied in accordance with its terms,
the Owner Trustee) during the continuance of an Event of Default upon receipt of
written notice specifying such Event of Default (which shall have been copied to
the Lessee); (i) not contain any purchase option in favor of the Permitted
Sublessee or any other terms which would prohibit the Lessee from performing its
obligations hereunder or prohibit the Lessor from exercising its rights and
remedies hereunder and (j) shall include provisions for the maintenance,
operation, possession and inspection of the Aircraft that are the same in all
material respects as the applicable provisions of this Lease.

          Subject to the Lessee's obligations in paragraph (x) above, the Lessee
shall (i) notify the Lessor at least 15 days prior to entering into any Sublease
stating the name of the proposed Permitted Sublessee and providing a copy of the
proposed Sublease, (ii) deliver a copy of the executed Sublease promptly (but no
later than 10 days) after execution thereof, (iii) obtain the consent of the
Permitted Sublessee to the assignment of its Sublease to the Lessor, and by the
Lessor to the Indenture Trustee pursuant to the Indenture, and (iv) cause a
sublease assignment and an Indenture Supplement and financing statements or
similar documents under the Applicable Laws of the country of the Permitted
Sublessee confirming the first priority security interest of the Lessor in such
Sublease (subject to Permitted Liens) (which security interest shall be assigned
by the Lessor to the Indenture Trustee pursuant to the Indenture), to be duly
executed and delivered and duly filed or recorded in all appropriate places.

          The Lessor hereby agrees for the benefit of the lessor or secured
party of any engine (other than the Engines) or of any airframe (other than the
Airframe) leased to the Lessee or purchased by the Lessee subject to a
conditional sale or other security agreement, which lease or conditional sale or
other security agreement (in the case of any such airframe) also covers an
engine or engines (other than the Engines) owned by the lessor under such lease
or subject to a security interest in favor of the secured party under such
conditional sale or other security agreement, that the Lessor will not acquire
or claim, as against such lessor or secured party, any right, title or interest

                                     -14-
<PAGE>

in any such engine as the result of such engine being installed on the Airframe
at any time while such engine is owned by such lessor or is subject to such
conditional sale or other security agreement or security interest in favor of
such secured party; provided, however, that such agreement of the Lessor shall
                    --------  -------
not be for the benefit of any lessor or secured party of any airframe leased to
the Lessee or owned or purchased by the Lessee subject to a conditional sale or
other security agreement or for the benefit of any mortgagee of or any other
holder of a security interest in an airframe owned by the Lessee, unless such
lessor, conditional vendor, other secured party or mortgagee has agreed (which
agreement may be contained in such lease, conditional sale or other security
agreement or mortgage and may consist of a paragraph similar to this paragraph)
that neither it nor its successors or assigns will acquire, as against the
Lessor, any right, title or interest in an Engine as a result of such Engine
being installed on such airframe.

          (c) Operation and Use.
              -----------------

          The Lessee shall not (and will not permit any Permitted Sublessee)
operate, use or locate the Airframe or any Engine, or suffer such Airframe or
any Engine to be operated, used or located (i) in any area excluded from
coverage by any insurance required by the terms of Section 9 hereof, except in
the case of a requisition by the United States of America where the Lessee
obtains (and provides evidence of) indemnity from the Government for the benefit
of the Additional Insureds against substantially the same risks and for at least
the amounts of the insurance required by Section 9 hereof covering such area, or
(ii) outside the United States or Canada in any recognized or, in the Lessee's
reasonable judgment, threatened area of hostilities unless covered by war risk
insurance, or in either case unless the Airframe or such Engine is operated or
used under contract with the Government under which contract the Government
assumes liability for substantially the same risks in at least the same amounts
as would be covered by such insurance.  The Lessee shall not permit the Airframe
or any Engine to be maintained, serviced, repaired, overhauled, used or operated
during the Term in violation of any Applicable Law or in violation of any
airworthiness certificate, rule, regulation, order, license or registration
relating to the Aircraft or such Engines issued by any competent governmental
authority, unless (i) the validity thereof is being contested in good faith and
by appropriate proceedings which do not involve a non-de minimis danger of the
sale, forfeiture or loss of the Airframe or such Engine or the interest of the
Lessor, the Owner Participant, the Indenture Trustee and the Noteholders therein
or any risk of criminal liability or any material risk of civil liability
against Lessor, the Owner Participant, the Indenture Trustee or any Noteholders,
or (ii) it is not possible for the Lessee (or a Permitted Sublessee) to comply
with the laws of a jurisdiction other than the United States (or other than any
jurisdiction in which the Aircraft is then registered) because of a conflict
with the applicable laws of the United States (or such jurisdiction in which the
Aircraft is then registered), provided, however, that actions taken under (i)
                              --------  -------
and (ii) above will not result in the violation of any requirements of insurance
pursuant to Section 9.

          The Lessee shall not intentionally do or permit to be done anything
which will expose the Aircraft to penalty, forfeiture, impounding or detention,
appropriation, damage or destruction (other than any damage or destruction
arising in the ordinary course of operation of the Aircraft) or

                                     -15-
<PAGE>

(insofar as the same relates to the operation or use of the Aircraft) the
Lessor, the Owner Participant, the Indenture Trustee or any Noteholder to
criminal liability (and in the event of any forfeiture, impounding, detention or
appropriation of the Aircraft the Lessee shall take all such steps reasonably
open to it with a view to obtaining the immediate release of the Aircraft). The
Lessee shall not represent or hold out the Lessor, the Owner Participant, the
Indenture Trustee or any Noteholder as carrying goods or passengers on the
Aircraft or as being connected or associated with any operation of carriage
which may be undertaken by the Lessee or pledge the credit of the Lessor, the
Owner Participant, the Indenture Trustee or any Noteholder. So long as the
Indenture is in effect, the Lessee shall not on any occasion on which the
ownership of the Aircraft is relevant represent to third parties that title to
the Aircraft is held by the Lessor free of the Lien of the Indenture.


           (d) Maintenance.
               -----------

            The Lessee, at its own cost and expense, shall during the Term
service, repair, maintain, overhaul and test the Aircraft, the Airframe and each
Engine (and each engine that is not an Engine but is installed on the Aircraft)
or cause the same to be done in accordance with (1)(i) a maintenance program
approved by the Aeronautical Authority and (ii) maintenance standards required
by, or substantially equivalent to those required by, the FAA or the central
civil aviation authority of Canada, France, Germany, Japan, The Netherlands or
the United Kingdom, and shall keep or cause to be kept the Aircraft, the
Airframe and each Engine (or engine) in as good operating condition as
originally delivered hereunder, ordinary wear and tear excepted, in accordance
with all applicable FAA regulations for the Aircraft (including all FAA
airworthiness directives applicable to the Aircraft), in accordance with all
mandatory service bulletins and as required to keep all Manufacturer's or Engine
Manufacturer's warranties in effect, in compliance with any requirements under
the policies of insurance required by Section 9, and shall keep or cause to be
kept the Aircraft, the Airframe and each Engine in such operating condition as
may be necessary to enable all certificates, licenses, permits and
authorizations required for the use and operation of the Aircraft and each
Engine in the appropriate category for the nature of the operations of the
Aircraft including the airworthiness certification of the Aircraft to be
maintained in good standing at all times under the applicable rules and
regulations of the Aeronautical Authority, except when aircraft of the same
type, model or series as the Airframe (powered by engines of the same type as
those with which the Airframe shall be equipped at the time of grounding)
registered in the same country have been grounded by the Aeronautical Authority
and (2) except during periods when a Sublease is in effect, the same standards
Lessee uses with respect to similar aircraft of similar size in its fleet
operated (whether owned or leased) by Lessee in similar circumstances and during
any period in which a Sublease is in effect, the same standards the Permitted
Sublessee uses with respect to similar aircraft of similar size in its fleet and
operated (whether owned or leased) by the Permitted Sublessee in similar
circumstances and without in any way discriminating against the Aircraft by
reason of its leased status.  Nothing herein shall be deemed to prevent the
Lessee (or a Permitted Sublessee) from taking the Aircraft out of service for
maintenance or modifications permitted hereunder or storage in accordance with
applicable Aeronautical Authority requirements, the manufacturer's recommended
procedures and sound practice for such storage.  The Lessee shall maintain or
cause

                                     -16-

to be maintained all records, logs and other documents required by the
Aeronautical Authority to be maintained in respect of the Aircraft in English in
the manner as such Aeronautical Authority requires.  Lessee further agrees that
the Aircraft, Airframe and Engines will be maintained, used, serviced, repaired,
overhauled or inspected in compliance with Applicable Law with respect to the
maintenance of the Aircraft and compliance with each applicable airworthiness
certificate, license and registration relating to the Aircraft, Airframe or any
Engine issued by the Aeronautical Authority.

           (e) Registration
               ------------

           Except as otherwise permitted by Section 4.02(b) of the Participation
Agreement, or as otherwise required by the Transportation Code or rules,
regulations, or orders promulgated thereunder, or to the extent that such
registration cannot be effected or continued due to the Lessor's or the Owner
Participant's failure to comply with the citizenship or other eligibility
requirements for registration of commercial aircraft under the Transportation
Code or any rule, regulation or order promulgated thereunder, the Aircraft shall
be duly registered in the name of the Lessor under the Transportation Code at
all times during the Term; provided that the Lessor shall execute and deliver
                           --------
all such documents as the Lessee may reasonably request for the purpose of
effecting, continuing or (as provided in this Section 5(e) hereof and Section
4.02(b) of the Participation Agreement) changing such registration.

Section 6. Inspection.
           ----------

           At all times during the Term, but upon at least 15 days' prior notice
to the Lessee (unless an Event of Default shall have occurred and be continuing,
in which event a prior written notice of at least one (1) Business Day is
required) and at a time and place reasonably acceptable to the Lessee, the
Lessor, the Owner Participant, the Loan Participant and the Indenture Trustee or
their authorized representatives (which may include the Manufacturer) may at
their own expense (unless an Event of Default shall have occurred and be
continuing, in which event the Lessee shall bear such expense) and risk conduct
a visual walk-around inspection of the Aircraft (including on board inspection)
and any Engine and may include inspection of areas exposed by any open panels,
bays or the like, but shall not include opening any panels, bays or the like
without the express written consent of an authorized employee of the Lessee
(including a visual walk-around inspection of the Aircraft during any "C" check
or other heavy maintenance) and may inspect the books and records of the Lessee
relating to the operation and maintenance thereof and the Lessee shall provide
copies of such books and records to the inspecting party or their authorized
representatives at its or their reasonable request; provided that (a) any such
                                                    --------
inspection shall be subject to the safety, security and workplace rules
applicable at the location where such inspection is conducted and any applicable
governmental rules or regulations, and (b) in the case of an inspection during a
maintenance visit, such inspection shall not interfere with the normal conduct
of such maintenance visit or extend the time required for such maintenance visit
or, in any event, at any time interfere with the use or operation of the
Airframe or any Engine or with the normal conduct of the Lessee's or a Permitted

                                     -17-
<PAGE>

Sublessee's business.  All information obtained in connection with any such
inspection shall be held confidential by the Lessor, the Indenture Trustee, the
Owner Participant and the Noteholders and shall not be furnished or disclosed by
them to anyone other than (i) each other, their bank examiners, auditors,
accountants, insurance advisors, agents and legal counsel, (ii) any prospective
and permitted transferees of the Lessor, the Indenture Trustee, the Owner
Participant or any Noteholder who agree to hold such information confidential,
(iii) to the Indenture Trustee and rating agencies, if applicable, (to the
extent necessary to obtain or maintain ratings and indicating whether such
inspection shows compliance or non-compliance by the Lessee with its obligations
under the Operative Agreements), (iv) any Person with whom any Participant is in
good faith conducting negotiations relating to the possible transfer and sale of
such Participant's interest in the Trust Estate, the Aircraft or the Equipment
Notes, if such Person shall have entered into an agreement similar to that
contained in this Section 6 whereby such Person agrees to hold such information
confidential, and (v) except as may be required by an order of any court or
administrative agency or by any statute, rule, regulation or order of any
governmental authority (or, in the case of any Noteholder, to any bank examiner
or other regulatory personnel) or as may be necessary to enforce the terms of
the Operative Agreements, provided, however, that the Lessor, the Owner
                          --------  -------
Participant or the Loan Participant may during any time it is offering the
Aircraft for sale make customary disclosures to prospective purchasers of the
Aircraft or the Equipment Notes as to the then current flight and maintenance
status of the Aircraft.  The Lessor, the Owner Participant, the Indenture
Trustee and the Loan Participant shall have no duty to make any such inspection
and shall not incur any liability or obligation by reason of not making any such
inspection.

          In addition to any inspection as provided hereunder, upon each request
of Owner Participant to Lessee made not more than four times in a calendar year,
Lessee will make available to Owner Participant information with respect to the
cycles and hours of operation of the Airframe and Engines and the status of the
time controlled components of the Engines.

          If requested by Lessor, Owner Participant, Indenture Trustee or any
Noteholder, Lessee shall provide, or shall cause any Permitted Sublessee to
provide, the date (if then scheduled) upon which the Airframe undergoes its next
scheduled major check and, with respect to any Engine, the next scheduled off
the Airframe maintenance, and shall advise Lessor, Owner Participant, Indenture
Trustee and the relevant Noteholder of the name and location (if then known) of
the relevant maintenance performer.

          The Lessee shall furnish to the Lessor, the Owner Participant and the
Indenture Trustee such additional information concerning the location,
condition, use and operation of the Aircraft as the Lessor, the Owner
Participant or the Indenture Trustee may from time to time reasonably request.

Section 7.    Replacement and Pooling of Parts; Alterations,
              Modifications and Additions; Substitution of Engines.
              ----------------------------------------------------

              (a) Replacement of Parts.
                  --------------------

              Except as otherwise provided in the proviso to the third sentence
of Section 7(d) or if the Airframe or an Engine to which a Part relates has
suffered an Event of Loss, the Lessee, at its own cost and expense, will during
the Term promptly replace all Parts that may from time to time become worn out,
lost, stolen, destroyed, seized, confiscated, damaged beyond repair or
permanently rendered unfit for use for any reason whatsoever. In addition, in
the ordinary course of maintenance, service, repair, overhaul or testing, the
Lessee (or a Permitted Sublessee), at its own cost and expense, may remove any
Parts, whether or not worn out, lost, stolen, destroyed, seized, confiscated,
damaged beyond repair or permanently rendered unfit for use, provided that
                                                             --------
the Lessee (or such Permitted Sublessee), at its own cost and expense, shall,
except as otherwise provided in the proviso to the third sentence of
Section 7(d), replace such Parts as promptly as practicable with replacement
Parts or temporary replacement parts as provided in Section 7(c) hereof. All
replacement Parts shall be free and clear of all Liens except for Permitted
Liens and shall be in as good operating condition as, and shall 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.

              (b) Title to Parts.
                  --------------

              Except as otherwise provided in the proviso to the third sentence
of Section 7(d), all Parts at any time removed from the Airframe or any Engine
shall remain the property of the Lessor and subject to this Lease, no matter
where located, until such time as such Parts shall be replaced by Parts that
have been incorporated or installed in or attached to such Airframe or Engine
and that meet the requirements for replacement Parts specified in Section 7(a).
Immediately upon any replacement Part becoming incorporated or installed in or
attached to an Airframe or Engine as provided in Section 7(a), without further
act, (i) title to the replaced Part shall thereupon vest in the Lessee (or the
relevant Permitted Sublessee), in "as-is, where-is" condition, free and clear of
all rights of the Lessor and the Indenture Trustee and any Lessor's Liens and
shall no longer be deemed a Part hereunder; (ii) title to such replacement Part
shall thereupon vest in the Lessor (subject only to Permitted Liens); and (iii)
such replacement Part shall become subject to this Lease and be deemed part of
such Airframe or Engine, as the case may be, for all purposes hereof to the same
extent as the Parts originally incorporated or installed in or attached to such
Airframe or Engine.

              (c) Pooling or Parts Leasing.
                  ------------------------

              Any Part removed from the Airframe or from any Engine as provided
in Section 7(a) may be subjected by the Lessee (or a Permitted Sublessee) to a
pooling or parts leasing agreement or arrangement of a type customary in the
airline industry entered into in the ordinary course of the Lessee's (or such
Permitted Sublessee's) business (with respect to the landing gears however, only

                                     -19-
<PAGE>

with a Permitted Sublessee), provided that, the part replacing such removed Part
shall be incorporated or installed in or attached to such Airframe or Engine in
accordance with Sections 7(a) and 7(b) as promptly as practicable after the
removal of such removed Part.  In addition, any temporary replacement part when
incorporated or installed in or attached to the Airframe or any Engine in
accordance with Section 7(a) may be owned by another airline or vendor as
customary in the United States airline industry, subject to a pooling or parts
leasing arrangement, provided that the Lessee (or a Permitted Sublessee), at its
                     --------
expense as promptly thereafter as reasonably practicable, either (i) causes
title to such temporary replacement part to vest in the Lessor in accordance
with Section 7(b) by the Lessee (or such Permitted Sublessee) acquiring title
thereto for the benefit of the Lessor free and clear of all Liens except
Permitted Liens, at which time such temporary replacement part shall become a
Part and become subject to this Lease or (ii) replaces such temporary
replacement part by incorporating or installing in or attaching to such Airframe
or Engine a further replacement Part owned by the Lessee (or such Permitted
Sublessee) free and clear of all Liens except Permitted Liens and which meets
the requirements of Section 7(a) and by causing title to such further
replacement Part to vest in the Lessor in accordance with Section 7(b).

          (d) Alterations, Modifications and Additions.
              ----------------------------------------

          The Lessee, at its own cost and expense, shall make (or cause to be
made) alterations and modifications in and additions to the Airframe and any
Engine as may be required to be made from time to time during the Term by
Applicable Law or in order to maintain the insurance required under Section 9
regardless of upon whom such requirements are, by their terms, nominally
imposed; provided, that the Lessee may, in good faith and by appropriate
         --------
procedure, contest the validity or application of any such standard by
appropriate proceedings in any reasonable manner which does not materially
adversely affect the interests of the Lessor or the Lien of the Indenture and
does not involve any non-de minimis risk of sale, forfeiture or loss of the
Aircraft or the interest of any Participant therein or the first priority Lien
of the Indenture thereon, any material risk of civil penalty or any risk of
criminal liability being imposed on Lessor, Indenture Trustee or any
Participant.  In addition, the Lessee (or a Permitted Sublessee), at its own
cost and expense, may from time to time make or cause to be made such
alterations and modifications in and additions to the Airframe and any Engine as
the Lessee (or such Permitted Sublessee) may deem desirable in the proper
conduct of its business including, without limitation, removal of Parts which
Lessee (or such Permitted Sublessee) deems are obsolete or no longer suitable or
appropriate for use in the Aircraft, Airframe or such Engine so long as the
aggregate value of such removed Parts (based on their value as of the Delivery
Date) does not exceed $200,000, provided further that no such alteration,
                                --------
modification, removal or addition (i) diminishes the value, utility, estimated
residual value (with respect to the Airframe only), condition, remaining useful
life or airworthiness of such Airframe or Engine below the value, utility,
estimated residual value, condition, remaining useful life or airworthiness
thereof immediately prior to such alteration, modification or addition, assuming
such Airframe or Engine was then in the condition required to be maintained by
the terms of this Lease or (ii) causes the Aircraft to be limited use property,
except that the value (but not the utility, estimated residual value, condition,
remaining useful life or airworthiness) of the Aircraft may be reduced by the
value of

                                     -20-
<PAGE>

Parts which the Lessee (or such Permitted Sublessee) has removed as permitted
above. Title to all Parts incorporated or installed in or attached or added to
the Airframe or any Engine as the result of any alteration, modification or
addition effected by the Lessee (or a Permitted Sublessee) shall, without
further act, vest in the Lessor free and clear of any Liens except Permitted
Liens and become subject to this Lease; provided that the Lessee (or such
                                        --------
Permitted Sublessee) may, at any time during the Term, remove any such Part from
the Airframe or an Engine if (i) such Part is in addition to, and not in
replacement of or in substitution for, any Part originally incorporated or
installed in or attached to such Airframe or Engine at the time of delivery
thereof hereunder or any Part in replacement of, or in substitution for, any
such original Part, (ii) such Part is not required to be incorporated or
installed in or attached or added to such Airframe or Engine pursuant to the
terms of Section 5(d) or the first sentence of this Section 7(d) or pursuant to
the terms of any insurance policies required to be carried hereunder or under
any Applicable Law and (iii) such Part can be removed from such Airframe or
Engine without diminishing or impairing the value, condition, utility, estimated
residual value, remaining useful life or airworthiness which such Airframe or
Engine would have had at the time of removal had such alteration, modification
or addition not been effected by the Lessee (or such Permitted Sublessee)
assuming the Aircraft was otherwise maintained in the condition required by this
Lease. Upon the removal by the Lessee (or such Permitted Sublessee) of any such
Part as above provided, title thereto shall, without further act, vest in the
Lessee (or such Permitted Sublessee), in "as-is, where-is" condition, free and
clear of all rights of the Lessor and the Indenture Trustee and any Lessor's
Liens and such Part shall no longer be deemed a Part hereunder. Any Part not
removed by the Lessee (or a Permitted Sublessee) as above provided prior to the
return of the Airframe or respective Engine to the Lessor hereunder shall remain
the property of the Lessor; provided that nothing in this Section 7(d) shall
                            --------
prohibit the Lessee (or a Permitted Sublessee) from removing any seats from the
Aircraft (which seats while so removed shall remain in the possession of the
Lessee (or such Permitted Sublessee) and shall remain property of the Lessor
until such time as such seats shall be replaced in accordance with Section 7(a))
so long as the Aircraft when returned to the Lessor pursuant to Section 12
hereof shall be in the condition required thereby. Lessee will not permit the
Aircraft to be used other than primarily in passenger service and passenger
configuration.

          (e)  Substitution of Engines.
               -----------------------

          (i) So long as no Specified Default shall have occurred and be
continuing, the Lessee (or a Permitted Sublessee) shall have the right at its
option at any time, on at least 30 days' prior written notice to the Lessor, the
Owner Participant and the Indenture Trustee, to substitute, and (ii) if an Event
of Loss shall have occurred with respect to an Engine under circumstances in
which there has not occurred an Event of Loss with respect to the Airframe,
shall within 90 days of the occurrence of such Event of Loss and on at least
five days' prior written notice to the Lessor substitute, a Replacement Engine
for any Engine (or in the case of clause (ii), for the Engine suffering an Event
of Loss). In the case of a substitution for an Engine other than due to the
occurrence of an Event of Loss, the Engine replaced shall not then be installed
or held for use on the Airframe. In such event, immediately upon the fulfillment
of the conditions precedent described in

                                     -21-
<PAGE>

this Section 7(e) on the date set forth in such notice and without further act,
(i) title to the Replacement Engine shall thereupon vest in the Lessor free and
clear of all Liens (other than Permitted Liens), (ii) title to the replaced
Engine shall thereupon vest in the Lessee (or its designee), in "as-is, where-
is" condition, free and clear of all rights of the Lessor and the Indenture
Trustee and any Lessor's Liens and shall no longer be deemed an Engine
hereunder, and (iii) such Replacement Engine shall become subject to this Lease
and be deemed part of the Aircraft for all purposes hereof to the same extent as
the Engine originally installed on or attached to the Airframe. Prior to the
substitution of a Replacement Engine, the following conditions shall be
satisfied at the Lessee's sole cost and expense and the parties agree to
reasonably cooperate with the Lessee to the extent necessary to enable it to
timely satisfy such conditions:

                    (i)  the following documents shall be duly authorized,
               executed and delivered by the respective party or parties
               thereto, and an executed counterpart of each shall be delivered
               to the Lessor, the Owner Participant and, if the Indenture is in
               effect, the Indenture Trustee:

                         (A)  a Lease Supplement covering the Replacement
                    Engine, which shall have been duly filed for recordation
                    with the FAA;

                         (B)  so long as the Indenture shall not have been
                    satisfied and discharged in accordance with its terms, an
                    Indenture Supplement covering the Replacement Engine, which
                    shall have been duly filed for recordation with the FAA (or
                    such other Applicable Law of the country in which the
                    Aircraft may be registered in accordance with Section 5(e));

                         (C)  a full warranty bill of sale (as to title), in
                    form and substance satisfactory to the Lessor and the Owner
                    Participant, covering the Replacement Engine, executed by
                    the owner thereof in favor of the Lessor;

                         (D)  as long as the Indenture is in effect, such
                    documents as may be required under Section 5.06 of the
                    Indenture relating to the Replacement Engine;

                         (E)  (i) so long as the Indenture shall not have been
                    satisfied and discharged in accordance with its terms, such
                    Uniform Commercial Code financing statements covering the
                    security interests created by the Indenture (or any similar
                    statements or other documents required to be filed or
                    delivered pursuant to the laws of the jurisdiction in which
                    the Replacement Engine may be registered in accordance with
                    Section 5(e)) to protect the first priority security

                    statements as are deemed necessary or desirable by counsel
                    for any Participant or the Indenture Trustee to protect the
                    ownership interests of the Owner Trustee and the first
                    priority security interests of the Indenture Trustee in the
                    Replacement Engine;

                         (F)  an Officer's Certificate of the Lessee certifying
                    that (i) in the case of a voluntary replacement only, no
                    Specified Default shall have occurred and be continuing and
                    (ii) (x) in the case of a voluntary replacement, the
                    Replacement Engine has at least the same number of hours or
                    cycles (whichever is applicable) of operation on such
                    Replacement Engine remaining until the next scheduled life
                    limited part replacement as the Engine it replaces, assuming
                    such Engine had been maintained in the condition required
                    hereunder; or (y) in the case of a mandatory replacement,
                    the Lessee has not discriminated in its selection of the
                    Replacement Engine (based on the leased status of the
                    Aircraft);

                         (G)  an opinion of qualified FAA counsel, in form and
                    substance reasonably satisfactory to the recipients thereof,
                    as to the due recordation of the Lease Supplement, the
                    Indenture Supplement and all other documents or instruments
                    the recordation of which is necessary to perfect and protect
                    the rights of the Lessor and the Indenture Trustee in the
                    Replacement Engine and the Replacement Engine is free and
                    clear of all recorded Liens other than Permitted Liens;

                         (H)  to the extent that an engine warranty in respect
                    of such Replacement Engine is available to the Lessee, an
                    engine warranty assignment covering such Replacement Engine,
                    in substantially the form of the Engine Warranty Assignment
                    or otherwise in such form and substance satisfactory to the
                    Lessor and the Owner Participant and a consent to such
                    engine warranty assignment, in substantially the form of the
                    Engine Warranty Assignment or otherwise in such form and
                    substance satisfactory to the Lessor and the Owner
                    Participant; and

                         (I)  evidence that the insurance requirements of
                    Section 9 with respect to an Engine are satisfied and that
                    the insurance covering such Replacement Engine shall be of
                    the type usually carried by the Lessee (or, in the case of a
                    voluntary replacement, such Permitted

                    risks of the kind customarily insured against by the Lessee
                    (or, in the case of a voluntary replacement, such Permitted
                    Sublessee);

                    (ii)  the Lessee shall furnish (or cause to be furnished to)
               the Lessor, the Owner Participant and the Indenture Trustee with
               an opinion, reasonably satisfactory in form and substance to the
               Lessor, the Owner Participant and the Indenture Trustee, of the
               Lessee's counsel, which may be the Lessee's General Counsel or
               Associate General Counsel, to the effect that (x) such bills of
               sale or other documents reasonably requested by the Lessor, the
               Owner Participant or the Indenture Trustee are sufficient to
               convey title to such Replacement Engine to the Lessor and with
               respect to the effectiveness of the interests in the Indenture
               Estate which the Indenture purports to create; (y) the Lessor and
               the Indenture Trustee (as assignee of Lessor under the
               Indenture), are entitled to the benefits and protections of
               Section 1110 with respect to the Replacement Engine to the same
               extent as with respect to the replaced Engine immediately
               preceding such replacement, provided that if the replaced Engine
                                           --------
               was subject to an Event of Loss, then such opinion regarding
               Section 1110 shall be required only in the event that a
               replacement engine that can so qualify is available in the
               Lessee's fleet or is otherwise available to the Lessee (by
               exchange or otherwise) without material cost to Lessee and (z)
               the Lease Supplement, Indenture Supplement and Warranty Bill of
               Sale have been duly authorized and delivered;

                    (iii) either (x) the Owner Participant shall have received
               an opinion of independent tax counsel (selected by the Owner
               Participant and reasonably acceptable to the Lessee), reasonably
               satisfactory to the Owner Participant, to the effect that there
               shall be no risk of adverse tax consequences resulting from such
               replacement (and the Owner Participant shall use its best efforts
               to cause a timely opinion to be delivered) or (y) the Lessee
               shall have provided, or caused to be provided, an indemnity in
               respect of any adverse tax consequences reasonably satisfactory
               (or, in the case of any voluntary substitution, satisfactory) in
               form and substance to the Owner Participant; and

                    (iv)  as long as the Indenture is in effect, all conditions
               specified in Section 5.06 of the Indenture shall be satisfied.

          Upon satisfaction of all conditions to such substitution, (x) the
Lessor shall, at the expense of the Lessee, execute and deliver, and request the
Indenture Trustee to execute and deliver to the Lessee such bills of sale and
other documents and instruments as the Lessee shall reasonably request to
evidence the transfer to the Lessee and vesting of all right, title and interest
in and to the replaced Engine in the Lessee, in "as-is, where-is" condition,
free and clear of all right, title and

                                     -24-

interest of the Lessor and the Indenture Trustee, and any Lessor's Liens; (y)
the Lessor shall, at the request and expense of the Lessee, assign to the Lessee
all claims it may have against any other Person relating to an Event of Loss
giving rise to such substitution (other than those in respect of insurance
maintained by the Owner Participant, the Indenture Trustee or the Noteholders
pursuant to Section 9(f)) and shall exercise such rights as it has to cause such
assignment to be free and clear of the Lien of the Indenture and (z) subject to
Section 8(g), the Lessee shall be entitled to receive all insurance proceeds
(other than those reserved to others under Section 9(f) hereof) and proceeds in
respect of any Event of Loss giving rise to such replacement to the extent not
previously applied to the purchase price of the Replacement Engine as provided
in Sections 9(e)(i) and 8(e)(ii). Should the Lessee replace any Engine as
provided herein, all the provisions of this Lease and the Indenture relating to
the Engine being replaced shall be applicable to the Replacement Engine with the
same force and effect.

                    days in advance by the Lessee, which date shall be a
                    Termination Date not more than 150 days after the occurrence
                    of the Event of Loss or, if earlier, the first Termination
                    Date which occurs more than 3 Business Days following the

                    Termination Date, together with all unpaid Basic Rent, if
                    any, payable before such Termination Date plus (B) all
                    unpaid Supplemental Rent (other than Termination Value) due

               (b)  Effect of Replacement.
                    ---------------------

               rights of the Lessor and the Indenture Trustee in the Replacement
               Aircraft or, in the case of counsel in another jurisdiction, the
               taking of all action necessary in such jurisdiction for such
               purposes and the Replacement Airframe and the Replacement
               Engines, if any, are free and clear of all recorded Liens other
               than Permitted Liens;

                    (viii) The Lessor and the Indenture Trustee (as assignee of
               Lessor under the Indenture), shall be entitled to the benefits of
               Section 1110 with respect to such Replacement Aircraft to the
               same extent as with respect to the replaced Aircraft immediately
               preceding such replacement;

                    (ix)   Either (1) the Owner Participant shall have received
               an opinion of independent tax counsel (selected by the Owner
               Participant and reasonably acceptable to the Lessee), reasonably
               satisfactory to the Owner Participant, to the effect that there
               shall be no risk of adverse tax consequences resulting from such
               replacement (and the Owner Participant shall use its best efforts
               to cause a timely opinion to be delivered) or (2) the Lessee
               shall have provided, or caused to be provided, an indemnity in
               respect of any adverse tax consequences in form and substance
               satisfactory to the Owner Participant; and

                    (x)    As long as the Indenture is in effect, all conditions
               specified in Section 5.06 of the Indenture shall be satisfied.

                                     -30-

          Lessee shall reimburse the Lessor, the Owner Participant, the Loan
Participant and the Indenture Trustee for all reasonable out-of-pocket costs
(including reasonable attorneys' fees) incurred by them in connection with any
substitution of a Replacement Aircraft pursuant to this Section 8.

          (e)  Non-Insurance Payments Received on Account of an Event of Loss.
               --------------------------------------------------------------

          As between the Lessor and the Lessee, any payments on account of an
Event of Loss (other than insurance proceeds or other payments the application
of which is provided for in this Section 8 or elsewhere in this Lease, as the
case may be, or payments in respect of damage to the business or property (other
than the Aircraft) of the Lessee) with respect to the Aircraft, an Engine or any
Part received at any time by the Lessor or by the Lessee or any other Person
from any governmental authority or other Person will be applied as follows:

                    (i)   if such payments are received with respect to an Event
               of Loss as to the Aircraft, and the Airframe or the Airframe and
               the Engines or engines installed thereon are being replaced by
               the Lessee pursuant to Section 8(a)(i), such payments shall be
               paid over to, or retained by, the Lessee, provided that if the
                                                         --------
               Lessee has not completed such replacement, such payments shall be
               paid over to, or retained by, the Lessor as security, and upon
               completion of, or in connection with a closing for, such
               replacement, be paid over to or retained by the Lessee;

                    (ii)  if such payments are received with respect to an Event
               of Loss to an Engine that has been or is being replaced by the
               Lessee pursuant to the terms hereof, such payments shall be paid
               over to, or retained by, the Lessee, provided that if the Lessee
                                                    --------
               has not completed such replacement, such payments shall be paid
               over to, or retained by, the Lessor as security, and upon
               completion of, or in connection with a closing for, such
               replacement, be paid over to or retained by the Lessee; and

                    (iii) if such payments are received with respect to an Event
               of Loss as to the Aircraft, and if the Airframe or the Airframe
               and the Engines or engines installed thereon have not been and
               will not be replaced as contemplated by Section 8(a), (x) such
               payments shall be applied in reduction of the Lessee's obligation
               to pay the Termination Value and other amounts required to be
               paid by the Lessee pursuant to Section 8(a)(ii), to the extent
               not already paid by the Lessee, and, after the Termination Value
               and all amounts required to be paid to the Lessor pursuant to
               Section 8(a)(ii) shall be paid in full, shall be applied to
               reimburse the Lessee for such Termination Value up to the full
               amount thereof, and (y) the balance, if any, of such payment
               remaining thereafter shall be applied to reimburse the Lessee,
               the

                                     -31-
<PAGE>

               Owner Participant, the Loan Participant, the Indenture Trustee
               and the Lessor for their reasonable costs (including attorney's
               fees), if any, of procuring such payments, and (z) the balance
               remaining, if any, shall then be distributed between the Lessor
               and the Lessee as their interests may appear.

          (f)  Requisition for Use.
               -------------------

          In the event of a requisition for use by any government during the
Term of the Airframe and the Engines, if any, or engines installed on the
Airframe (including the Government pursuant to the CRAF Program), the Lessee
shall promptly notify the Lessor, the Owner Participant and the Indenture
Trustee of such requisition and, if the same does not constitute an Event of
Loss, all of the Lessee's obligations under this Lease shall continue to the
same extent as if such requisition had not occurred except to the extent that
the performance or observance of any obligation by the Lessee shall have been
prevented or delayed by such requisition, provided that the Lessee's obligations
                                          --------
for the payment of money and under Section 9 (except, in the case of Section 9,
while an assumption of liability by the government of the United States of the
scope referred to in Section 5(c) is in effect) and Section 12 shall not be
reduced, delayed or affected by such requisition.  Any payments received by the
Lessor or the Lessee from such government with respect to the use of such
Airframe or Engines during the Term shall be paid over to, or retained by, the
Lessee and any payments received by the Lessor or Lessee from such government
with respect to the use of the Airframe or Engines after the Term shall be paid
over to, or retained by, Lessor. In the event of an Event of Loss of an Engine
resulting from the requisition for use by a government of such Engine (but not
the Airframe), the Lessee will replace such Engine hereunder by complying with
the terms of Section 7(e) and any payments received by the Lessor or the Lessee
from such government with respect to such requisition shall be paid in
accordance with Section 8(e).

          (g)  Certain Payments to be Held As Security.
               ---------------------------------------

          Any amount referred to in this Section 8 or Section 9 hereof which is
payable to the Lessee shall not be paid to the Lessee, or, if it has been
previously paid directly to the Lessee, shall not be retained by the Lessee (and
pending delivery to the Lessor, shall be held in trust by the Lessee for the
benefit of the Lessor), if at the time of such payment a Specified Default shall
have occurred and be continuing, but shall be paid to and held by the Lessor as
security for the obligations of the Lessee under this Lease, unless and until
applied by Lessor to Lessee's obligations and at such time as there shall not be
continuing any such Specified Default, such amount and any gain realized as a
result of Permitted Investments required to be made pursuant to Section 15 or
Section 3.07 of the Indenture shall to the extent not so applied be paid over to
the Lessee.

          (h)  Notice of Damage.
               ----------------

          The Lessee shall notify the Lessor, the Owner Participant and the
Indenture Trustee as soon as practicable after the Lessee becomes aware of any
loss, theft, damage or destruction of

                                     -32-
<PAGE>

the Aircraft or any part thereof not constituting an Event of Loss if the
estimated cost of repair or replacement exceeds $1,000,000.

Section 9. Insurance.
           ---------

           (a)  Public Liability and Property Damage Insurance.
                ----------------------------------------------

           Subject to the rights of the Lessee under Section 9(d), the Lessee
shall, without expense to the Lessor, the Indenture Trustee or the Participants,
maintain or cause to be maintained in effect at all times during the Term, with
insurers of nationally or internationally recognized reputation and
responsibility which normally participate in airline insurance programs,
comprehensive airline public liability insurance (including, without limitation,
aircraft third party liability, baggage and mail and aviation general third
party liability, contractual liability, passenger legal liability, cargo
liability, property damage liability, general third party legal liability and
product liability coverage but excluding manufacturer's product liability
coverage) with respect to the Aircraft in an amount not less than the greater of
(i) the amount which Lessee may carry from time to time on other similar
aircraft in its fleet (whether owned or leased) and (ii) the Minimum Liability
Amount; provided that an agreement of the Government for the benefit of the
        --------
Additional Insureds to insure against or indemnify for substantially the same
risks to at least the same amount shall satisfy the requirements of this Section
9(a), provided that on or prior to the date of such agreement, the Lessee shall
      --------
provide an Officer's Certificate of the Lessee certifying that any such
insurance or indemnity provides protection no less favorable than insurance
coverage that would comply with this Section 9.  Such insurance shall be of the
same type and covering the same risks usually carried by the Lessee with respect
to similar aircraft and engines and shall provide coverage that is in
substantially similar form, of such types and having limits within the range of
limits (but no less than the Minimum Liability Amount) as are customarily
obtained by similarly situated United States carriers operating similar aircraft
on similar routes.

           During any period that the Aircraft is grounded and not in operation
for any reason, the Lessee may modify the insurance required by this Section
9(a) to modify the amounts of public liability and property damage insurance,
the scope of the risks covered and the type of insurance, in all circumstances
to conform to such insurance customary in the United States airlines industry
for regional air carriers similarly situated with the Lessee in respect of
similar aircraft which are grounded, not in operation, and stored or hangared,
except that in all instances, the amounts of coverage and scope of risk covered
and the type of insurance shall be at a minimum no less favorable than the
insurance as from time to time applicable to aircraft owned or leased by Lessee
on the ground, not in operation, and stored or hangared.

           (b)  Insurance Against Loss or Damage to the Aircraft and Engines.
               ------------------------------------------------------------

           Subject to the rights of the Lessee under Section 9(d), the Lessee
shall, without expense to the Lessor, the Indenture Trustee or the Participants,
maintain or cause to be maintained

                                     -33-
<PAGE>

in effect at all times during the Term with insurers of nationally recognized
responsibility which normally participate in airline insurance programs (i) all
risk (including U.S. limited form of war risk insurance covering (but not
limited to) hijacking, strikes, civil commotion, terrorist acts and acts of
sabotage while the Aircraft is operated in the U.S. and Canada), agreed value,
ground, taxiing and flight hull insurance, which may, except as expressly
provided in this Section 9(b), exclude war risks and allied perils, covering the
Aircraft for an amount at all times (even when the Aircraft is grounded or in
storage) not less than the Termination Value from time to time; provided that,
                                                                -------------
neither the Lessee nor any Permitted Sublessee shall be required to maintain
all-risk flight aircraft hull insurance with respect to any period in which the
Aircraft is grounded and properly stored or hangared. Such insurance shall not
provide insurers with a right to replace the Airframe or any Engine with another
airframe or Engine. Such hull insurance or other personal property insurance of
the Lessee (or a Permitted Sublessee) shall cover Engines or engines and Parts
temporarily removed from the Airframe, pending replacement by installation of
the same or similar Engines, engines or Parts on the Airframe. Such insurance
shall be on a replacement cost basis in respect of damage not constituting an
Event of Loss and on an agreed value basis in respect of an Event of Loss and
shall be of the same type and covering the same risks usually carried by the
Lessee with respect to similar aircraft and engines and shall provide coverage
that is in substantially similar form, of such types and having limits within
the range of limits (but no less than Termination Value from time to time) as
are customarily obtained by similarly situated United States carriers operating
similar aircraft on similar routes. If and to the extent that the Lessee or a
Permitted Sublessee operates the Aircraft (A) on routes where it maintains war
risk, hijacking or allied perils insurance in effect with respect to other
similar owned or leased aircraft in its fleet, (B) on routes where the custom in
the industry is to carry war risk, hijacking or allied perils insurance or (C)
in any area of recognized hostilities, the Lessee or such Permitted Sublessee
shall maintain or cause to be maintained such insurance in effect with respect
to the Aircraft in the amount at least equal to Termination Value from time to
time. An agreement by the Government to insure against or indemnify for
substantially the same risks to at least the same amount will satisfy any of the
requirements of this Section 9(b). Notwithstanding the foregoing, the Lessee
shall not be required to maintain war risk insurance (except the U.S. limited
form of war risk insurance noted above) so long as the Aircraft is operated only
within the United States and Canada.

          During any period that the Aircraft is on the ground and not in
operation, the Lessee may carry or cause to be carried, in lieu of the insurance
required by this Section 9(b), insurance otherwise conforming with the
provisions of this Section 9(b) except that the scope of the risks and the type
of insurance shall be in substantially similar form, of such types and having
limits within the range of limits (but no less than Termination Value from time
to time) as are customarily obtained by similarly situated United States
carriers in respect of similar aircraft which are grounded, not in operation,
and stored or hangared, provided that the scope of the risks and the type of
                        --------
insurance shall be the same as from time to time applicable to aircraft owned by
the Lessee of the same type similarly on the ground and not in operation,

provided further that the Lessee shall maintain insurance against risk of loss
- -------- -------
or damage to the Aircraft in an amount equal to the

                                     -34-
<PAGE>

Termination Value from time to time during such period that the Aircraft is on
the ground and not in operation.

          (c)  Additional Insureds; Loss Payment.
               ---------------------------------

          The Lessee shall cause all policies of insurance carried in accordance
with this Section 9 to name the Additional Insureds as their respective
interests may appear as additional insureds.  Such policies shall provide with
respect to such Additional Insureds that (i) none of their respective interests
in such policies shall be invalidated by any act or omission or breach of
warranty or condition contained in such policies by the Lessee or any other
Person (other than such Additional Insured) or, in the case of any particular
Additional Insured, any other Additional Insured and shall insure the respective
interests of the Additional Insureds regardless of any breach or violation of
any warranty, declaration or condition contained in such policies by the Lessee
or any Permitted Sublessee; (ii) in the case of any particular Additional
Insured, no cancellation or lapse of coverage for nonpayment of premium or
otherwise, and no substantial change of coverage which adversely affects the
interests of any such Additional Insured, shall be effective as to such
Additional Insured until thirty (30) days (or such lesser period as may be
applicable in the case of any war risk coverage) after receipt by such
Additional Insured of written notice from the insurers of such cancellation,
lapse or change; (iii) they shall have no liability for premiums, commissions,
calls, assessments or advances with respect to such policies; (iv) such policies
will be primary without any right of contribution from any other insurance
carried by such Additional Insureds; (v) the insurers waive any rights of set-
off (including for unpaid premiums), counterclaim, deduction or subrogation
whether by attachment or otherwise, against such Additional Insureds; (vi) such
policies shall apply worldwide and have no territorial restrictions or
limitations (except, in the case of war, hijacking or related perils insurance,
as otherwise permitted hereunder); (vii) shall contain a 50/50% Clause per
Lloyd's Aviation Underwriter's Association Standard Policy Form AVS 103; and
(viii) losses shall be adjusted with the Lessee (or, if an Event of Default
shall have occurred and be continuing, with the loss payee referred to in the
last sentence of this Section 9(c)); provided, that, in the case of an Event of
                                     --------
Loss, no adjustment (other than hull deductibles) shall reduce the amount
payable under such policy to less than the agreed value required by Section
9(b).  Each liability policy shall provide that all the provisions thereof,
except the limits of liability, shall operate in the same manner as if there
were a separate policy covering each insured and each hull policy shall provide
that the exercise by the insurer of rights of subrogation derived from rights
retained by the Lessee will not delay payment of any claim that would otherwise
be payable but for such rights of subrogation. Each hull policy shall name the
Indenture Trustee as loss payee as long as the Indenture shall remain in effect
and thereafter shall name the Lessor as loss payee; provided that, so long as
                                                    -------- ----
the insurers shall not have received written notice that an Event of Default has
occurred and is continuing, if insurance proceeds under a hull policy in the
aggregate equal $1,000,000 or less, then such proceeds shall be payable to the
Lessee and, notwithstanding the foregoing, any amounts (i) of any proceeds which
in the aggregate exceed $1,000,000, (ii) of any proceeds in respect of a total
loss or an Event of Loss or (iii) if the insurers shall have received written
notice that an Event of Default has occurred and is continuing, any proceeds
with respect to any single loss, shall be payable to such loss payee.

                                     -35-
<PAGE>

          (d)  Deductibles and Self-Insurance.
               ------------------------------

          The Lessee may from time to time self-insure, by way of deductible or
premium adjustment provisions in insurance policies or otherwise, the risks
required to be insured against pursuant to this Section 9 under a program
applicable to all aircraft in the Lessee's fleet in such amounts as are then
self-insured with respect to similar owned or leased aircraft in the Lessee's
fleet but in no case shall such self-insurance in the aggregate exceed, in
addition to the Lessee's normal deductible per occurrence relating to damage
(but not total loss) to aircraft for each aircraft in the Lessee's fleet (which
normal deductible amount shall not exceed $500,000 in respect of the Aircraft),
an amount equal to 3% of the Lessee's tangible net worth (but in no event to
exceed $15,000,000 (including, for purposes of calculating the amount of
$15,000,000, the amount of such normal deductible applicable to the Aircraft
(but not any other aircraft in the Lessee's fleet))), calculated as at the end
of the Lessee's immediately preceding fiscal year.

          (e)  Application of Hull Insurance Proceeds.
               --------------------------------------

          Subject to Section 8(g), as between the Lessor and the Lessee, any
payments received under policies of hull or other property insurance required to
be maintained by the Lessee pursuant to Section 9(b), shall be applied as
follows:

                    (i)   if such payments are received with respect to loss or
               damage (including an Event of Loss with respect to an Engine) not
               constituting an Event of Loss with respect to the Airframe,
               payments in the aggregate of $1,000,000 or less shall be paid
               over to or retained by the Lessee and any payments which in the
               aggregate are greater than $1,000,000 shall be paid over to or
               retained by the Lessor for payment to the Lessee only upon
               performance of its repair or replacement obligation;

                    (ii)  if such payments are received with respect to an Event
               of Loss with respect to the Airframe and the Airframe is not
               being replaced by the Lessee pursuant to Section 8(a)(i), so much
               of such payments as shall not exceed the Termination Value and
               other amounts required to be paid by the Lessee pursuant to
               Section 8(a)(ii) shall be applied in reduction of the Lessee's
               obligation to pay such amounts if not already paid by the Lessee,
               and to reimburse the Lessee if such amounts shall have been paid,
               and the balance, if any, of such payments shall be promptly paid
               over to or retained by the Lessee; and

                    (iii) if such payments are received with respect to the
               Airframe or the Airframe and Engines or engines installed thereon
               and the Airframe is being replaced by the Lessee pursuant to
               Section 8(a)(i), such payments shall be paid over to, or retained
               by the Lessee, provided that if the Lessee has not
                              --------

                                     -36-
<PAGE>

               completed such replacement and the performance of all other
               obligations under Section 8(d), such payments shall be paid over
               to, or retained by, the Lessor as security, and upon completion
               of, or in connection with a closing for, such replacement, be
               paid over to or retained by the Lessee.

          (f)  Insurance for Own Account.
               -------------------------

          Nothing in this Section 9 shall prohibit the Lessor, the Owner
Participant, the Lessee, the Indenture Trustee or the Noteholders or any
Additional Insured from obtaining insurance with respect to the Aircraft for its
own account (including, without limitation, in the case of the Lessee, hull
insurance under the same policies maintained pursuant to this Section 9 in
amounts in excess of those required to be maintained pursuant to this Section 9)
and any proceeds payable thereunder shall be payable as provided in the
insurance policy relating thereto, provided that no such insurance may be
                                   --------
obtained which would limit or otherwise adversely affect the availability of
coverage or payment of any insurance required to be obtained or maintained
pursuant to this Section 9, it being understood that all salvage rights to the
Airframe or the Engines shall remain with the Lessee's insurers at all times.

          (g)  Reports, etc.
               ------------

          Lessee will furnish, or cause to be furnished, to the Lessor, the
Owner Participant and the Indenture Trustee (A) on or prior to the Delivery
Date, insurance certificates describing in reasonable detail the insurance
maintained by Lessee as required pursuant to this Section 9, (B) prior to the
cancellation, lapse or expiration of the insurance policies required pursuant to
this Section 9, evidence of renewal of such insurance policies, and (C) on or
prior to the Delivery Date and on or before the renewal dates of the insurance
policies carried by the Lessee pursuant to this Section 9, a report signed by a
firm of recognized aircraft insurance brokers of good reputation, not affiliated
with the Lessee, which brokers may be regularly retained by the Lessee and
reasonably satisfactory to the Lessor, stating the opinion of such firm that (i)
all premiums in connection with the insurance then due have been paid, (ii)  the
insurance then carried and maintained on the Aircraft complies with the terms
hereof and, in the case of renewal insurance, that such renewal insurance will
on and after the effective date thereof so comply with the terms hereof and
(iii) to the best of such firm's knowledge, such insurance provides coverage
that is in substantially similar form, of such types and having limits within
the range of limits as are customarily obtained by similarly situated United
States carriers operating similar aircraft on similar routes, provided that all
                                                              --------
information contained in such report shall be held confidential by the Lessor,
the Indenture Trustee and the Owner Participant, and shall not be furnished or
disclosed by them to any Person except (A) their legal counsel, independent
certified public accountants, insurance brokers or advisors or other agents who
agree to hold such information confidential, (B) to any Noteholder or to bona
fide prospective and permitted transferees of any Participant and their
respective agents (provided that each such transferee shall agree for the
                   --------
benefit of the Lessee to hold all such information similarly confidential), (C)
as may be required by Applicable Law or by any court or administrative order or

                                     -37-

decree or governmental ruling or regulation (or, in the case of any Noteholder,
to any bank examiner or other regulatory personnel), (D) as may be necessary for
purposes of enforcement of Operative Agreements or (E) to the Security Trustee
or rating agencies. The Lessee will instruct such firm to give prompt written
advice to the Lessor, the Owner Participant and the Indenture Trustee of any
default in the payment of any premium and of any other act or omission on the
part of the Lessee (or any Permitted Sublessee) of which it has knowledge and
which would in such firm's opinion invalidate or render unenforceable, in whole
or in any material part, any insurance on the Aircraft. The Lessee will also
instruct such firm to advise the Lessor, the Owner Participant and the Indenture
Trustee in writing at least thirty (30) days prior to the termination or
cancellation of, or material adverse change in, such insurance carried and
maintained on the Aircraft pursuant to this Section 9 (or such lesser period as
may be applicable in the case of war risk coverage), provided, that in respect
                                                     --------
of war risk or allied perils coverage, if the notice period specified above is
not obtainable, the insurance broker shall provide for as long a period of prior
notice as shall then be obtainable.

          (h)  Right to Pay Premiums.
               ---------------------

          The Additional Insureds shall have the rights but not the obligations
of an additional named insured. None of Lessor, Owner Participant, Indenture
Trustee and the other Additional Insureds shall have any obligation to pay any
premium, commission, assessment or call due on any such insurance (including
reinsurance). Notwithstanding the foregoing, in the event of cancellation of any
insurance due to the nonpayment of premiums, each of Lessor, Owner Participant,
Indenture Trustee and the other Additional Insureds shall have the option, in
its sole discretion, to pay any such premium in respect of the Aircraft that is
due in respect of the coverage pursuant to this Lease and to maintain such
coverage, as Lessor, Owner Participant, Indenture Trustee or the other
Additional Insureds may require, until the scheduled expiry date of such
insurance and, in such event, Lessee shall, upon demand, reimburse Lessor, Owner
Participant, Indenture Trustee and the other Additional Insureds for amounts so
paid by them.

          (i)  Spares Physical Damage Insurance.
               --------------------------------

          During any period that an Engine is not attached to the Airframe or
any other airframe and not otherwise subject to coverage by a hull policy
maintained by the Lessee (or a Permitted Sublessee), the Lessee shall maintain
or cause to be maintained spares physical damage insurance covering such Engine
in an aggregate amount not less than the amount commercially available in
aviation insurance markets except that the scope of the risks and the type of
insurance shall be in substantially similar form, of such types and having
limits within the range of limits as are customarily obtained by similarly
situated United States carriers operating similar engines not attached to any
airframe, provided that the scope of the risks and the type of insurance shall
          --------
be the same as from time to time applicable to engines owned or leased by the
Lessee of the same type and similarly not attached to any airframe.

Section 10.    Liens.
               -----

                                     -38-
<PAGE>

              The Lessee shall not during the Term directly or indirectly
create, incur, assume or suffer to exist any Lien on or with respect to the
Aircraft, Airframe, any Engine or any Part or title thereto or any interest
therein or in this Lease except (a) the respective rights of the Lessor and the
Lessee as provided herein, the Lien of the Indenture and the rights of the
parties to the other Operative Agreements; (b) the rights of others under
agreements or arrangements to the extent expressly permitted in Sections 5(b)
and 7(c); (c) Liens for Taxes of the Lessee either not yet due or being
contested in good faith by appropriate proceedings (and for which adequate
reserves have been provided in accordance with generally accepted accounting
principles) so long as such proceedings do not involve any non-de minimis risk
of the sale, forfeiture or loss of the Aircraft, Airframe or an Engine or the
interest of any Participant therein or any risk of criminal liability or any
material risk of civil penalty against Lessor, Indenture Trustee or any
Participant; (d) Liens of suppliers, mechanics, workers, repairers, employees,
airport operators, air traffic control authorities or other like Liens arising
in the ordinary course of business and for amounts the payment of which is
either not yet delinquent or is being contested in good faith (and for the
payment of which adequate reserves have been provided in accordance with
generally accepted accounting principles) by appropriate proceedings, so long as
such proceedings do not involve a non-de minimis risk of the sale, forfeiture or
loss of the Airframe or an Engine or the interest of any Participant therein or
any risk of criminal liability or any material risk of civil penalty against
Lessor or any Participant; (e) Liens arising out of judgments or awards against
the Lessee with respect to which an appeal or proceeding for review is being
prosecuted in good faith and with respect to which at the time there shall have
been secured a stay of execution, so long as such proceedings do not involve a
non-de minimis risk of the sale, forfeiture or loss of the Aircraft, Airframe or
an Engine or the interest of any Participant therein; (f) Lessor's Liens and
Indenture Trustee's Liens; (g) salvage and similar rights of insurers under
policies of insurance maintained with respect to the Aircraft and (h) Liens with
respect to which the Lessee (or any sublessee) has provided a bond or other
security adequate in the good faith opinion of the Lessor, the Owner Participant
and the Indenture Trustee. Liens described in clauses (a) through (h) above are
referred to herein as "Permitted Liens." The Lessee shall promptly, at its own
expense, take such action as may be necessary to duly discharge (by bonding or
otherwise) any Lien other than a Permitted Lien arising at any time during the
Term.

Section 11.   Recordation and Further Assurances.
              ----------------------------------

              (a)  Recordation of Lease.
                   --------------------

              The Lessee shall cause this Lease, any Lease Supplements, and any
and all additional instruments which shall be executed pursuant to the terms
hereof to be kept, filed and recorded and to be re-executed, refiled and re-
recorded at all times during the Term with the FAA or other Aeronautical

Trustee on the Indenture Estate.

              (b)  Further Assurances.
                   ------------------

                                     -39-
<PAGE>

          The Lessee and the Lessor will each promptly and duly execute and
deliver to the other such further documents and assurances and take such further
action as the other may from time to time reasonably request in order to more
effectively carry out the intent and purpose of this Lease and to establish and
protect the rights and remedies created or intended to be created in favor of
the Lessor and the Lessee hereunder, including, without limitation, if requested
by the Lessor or the Lessee, the execution and delivery of supplements or
amendments hereto, in recordable form, subjecting any replacement or substituted
aircraft or engine to this Lease and the recording or filing of counterparts
hereof, or of financing statements with respect hereto.

          (c)  Markings.
               --------

          On or reasonably promptly after the Delivery Date, Lessee will cause
to be affixed to, and maintained in, the cockpit of the Airframe and on each
Engine, in a clearly visible location (it being understood that the location of
such placard, as identified to the Owner Participant and the Loan Participant
prior to the Delivery Date, shall be deemed to be in compliance with this
requirement), a placard of a reasonable size and shape bearing the legend, in
English, set forth below:

                                  Leased from

               First Union Trust Company, National Association,
                        not in its individual capacity
                 but solely as Owner Trustee, Owner and Lessor

                               and Mortgaged to

                                Allfirst Bank,
                        not in its individual capacity
                        but solely as Indenture Trustee

Such placard to be replaced, if necessary, with a placard reflecting the name of
any successor Owner Trustee or Indenture Trustee, as the case may be, as
permitted under the Operative Agreements. Such placard may be removed
temporarily, if necessary, in the course of maintenance of the Airframe.  If
such placard is damaged or becomes illegible, Lessee shall promptly replace it
with a placard complying with the requirements of this Section 11(c).

Except as above provided, neither the Lessee nor any Permitted Sublessee will
permit the name of any person to be placed on the Airframe or any Engine in a
manner that may be interpreted as a claim of ownership of, or Lien on, the
Airframe or any Engine; provided, however, that nothing herein contained shall
                        --------  -------
prohibit the Lessee (or any Permitted Sublessee) from placing its customary

                                     -40-

the Aircraft in its livery.

Section 12.    Return of Aircraft and Records.
               ------------------------------

               (a)  Return of Aircraft.
                    ------------------

               Upon the termination of this Lease at the expiration of the Term
or upon the earlier termination of this Lease pursuant to the terms hereof,
unless the Lessee shall purchase the Aircraft or there shall have been an Event
of Loss with respect to the Aircraft, the Lessee, at its own expense, shall,
except as otherwise expressly provided herein, return the Airframe by delivering
the same to the Lessor in the continental United States of America at a location
on the Lessee's domestic route system chosen by the Lessee and reasonably
acceptable to the Lessor, fully equipped with two Engines or other General
Electric CF34-3B1 Series 200 engines (or engines of the same manufacturer of a
comparable or an improved model and suitable for installation and use on the
Airframe and owned by the Lessee) duly installed thereon.

               (b)  Return of Other Engines.
                    -----------------------

               In the event any engine not owned by the Lessor shall be returned
with the Airframe, such engine shall satisfy the requirements for a Replacement
Engine, shall be free and clear of all Liens other than Lessor's Liens and shall
have a value, remaining useful life, utility and condition at least as great as
the Engine replaced (assuming such Engine was maintained in accordance with the
terms hereof) and the Lessee shall, at its own expense and concurrently with
such return, furnish the Lessor with (i) a full warranty bill of sale guaranteed
by Lessee, in form and substance reasonably satisfactory to the Lessor and the
Owner Participant, (ii) an Officer's Certificate as described in Section
7(e)(i)(F), and (iii) an opinion of counsel to the Lessee as described in
Section 7(e)(ii), with respect to each such engine and shall take such other
action as required by Section 7(e) to cause such engine to be a Replacement
Engine or as the Lessor may reasonably request in order that such engine shall
be duly and properly titled in the Lessor free and clear of all Liens other than
Lessor's Liens. Upon passage of title such engine shall be deemed to be an
Engine for all purposes hereof and thereupon the Lessor will transfer to the
Lessee, in "as-is, where is" condition, without recourse or warranty except a
warranty against Lessor's Liens, all right, title and interest of the Lessor or
any Affiliate in and to an Engine not installed on the Airframe at the time of
the return thereof and, if the Indenture has not been discharged, shall request
that the Indenture Trustee release such Engine from the Lien of the Indenture.

               (c)  Fuel; Records.
                    -------------

               Upon the return of the Aircraft, (i) the Lessor shall have no
obligation with respect to the amount of fuel or oil contained in the Airframe
and (ii) the Lessee shall deliver to the Lessor all logs, manuals, certificates
and inspection, modification and overhaul records which are required to be
maintained with respect thereto under applicable rules and regulations of the
FAA and DOT.

<PAGE>

               (d)  Condition of Aircraft.
                    ---------------------

               The Aircraft when returned to the Lessor shall be in the
operating condition required by Exhibit F hereto.

               (e)  Failure to Return. If Lessee shall, for any reason
                    -----------------
whatsoever, fail to return the Aircraft and the documents referred to in Section
12(c)(ii) at the time and place and in the condition specified herein, all
obligations of Lessee under this Lease shall continue in effect with respect to
the Aircraft until the Aircraft is so returned to Lessor and Lessee shall pay to
Lessor an amount equal to the average daily Basic Rent payable by Lessee during
the Term for each day after the end of the Term to but excluding the day of such
return; provided, however, that this Section 12(e) shall not be construed as
        --------  -------
permitting Lessee to fail to meet its obligations to return the Aircraft or the
documents referred to in Section 12(c)(ii) in accordance with the requirements
hereof or constitute, or be deemed to constitute, a waiver of any Event of
Default resulting from Lessee's failure to return the Aircraft or such documents
or otherwise; and provided, further, that Lessee shall not be responsible for
                  --------  -------
Lessor's failure to accept return of the Aircraft and the documents referred to
in Section 12(c)(ii) in accordance with the requirements hereof in a timely
manner or for any rent with respect to periods after Lessee has tendered the
Aircraft and the documents referred to in Section 12(c)(ii) for return in
accordance with this Lease, provided however that if Lessor's inspection of the
                            -------- -------
Aircraft and the documents referred to in Section 12(c)(ii), which inspection
shall be conducted in good faith and timely manner, reveals any discrepancy from
the condition required by the provisions of this Section 12, Lessee shall
continue to pay rent in accordance with this Section 12(e) until the Aircraft
and the documents referred to in Section 12(c)(ii) are returned to the Lessor in
accordance with this Lease. Any rent owed to Lessor pursuant to this Section
12(e) shall be payable upon acceptance of the Aircraft and the documents
referred to in Section 12(c)(ii) by Lessor.

               (f)  Storage and Related Matters.
                    ---------------------------

               If Lessor gives written notice to Lessee not less than 60 days
nor more than 180 days prior to the end of the Term requesting storage of the
Aircraft upon its return hereunder, Lessee will provide Lessor, or cause Lessor
to be provided, with outdoor parking facilities for the Aircraft for a period up
to 60 days, commencing on the date of such return, at such storage facility in
the 48 contiguous states of the United States as Lessee may select. Lessee
shall, at Lessor's written request, maintain insurance (if available) for the
Aircraft during such storage period, provided that Lessor shall reimburse Lessee
                                     --------
for Lessee's out-of-pocket cost of providing such insurance. Such storage shall
be at Lessor's risk, and Lessor shall pay all applicable storage fees, except
that Lessee shall pay the parking fees for the initial 60 day storage period;
provided that Lessee's obligation to provide parking shall be subject to Lessee
- --------
and Lessor entering into an agreement prior to the commencement of the storage
period with the storage facility providing, among other things, that Lessee
shall pay only the parking fees for the initial storage period of up to 60 days
and that Lessor shall bear all maintenance charges and other costs incurred
relating to such storage.

Section 13.    Renewal Option and Purchase Options.
               -----------------------------------

               (a)  Renewal Terms.
                    -------------

               Subject to the final sentence of this Section 13(a), upon
expiration of the Basic Term, the Lessee shall have the right to extend this
Lease for successive periods of one or two years each (each a "Fixed Renewal
Term"), but for not more than an aggregate of three years. Subject to the final
sentence of this Section 13(a), upon expiration of the Basic Term or at the end
of any Fixed Renewal Term, the Lessee shall have the right to extend this Lease
for any number of successive periods of one year each (each a "Fair Market Value
Renewal Term"; each Fixed Renewal Term and each Fair Market Value Renewal Term,
being hereinafter sometimes called a "Renewal Term") provided that the aggregate
term of all Renewal Terms shall not exceed six years. A Fixed Renewal Term will
commence at the end of the Basic Term or the preceding Fixed Renewal Term, as
the case may be and a Fair Market Value Renewal Term will commence at the end of
the Basic Term or the preceding Renewal Term, as the case may be. Such right to
extend this Lease shall be exercised upon notice to the Lessor, specifying the
nature and duration of the Renewal Term, not less than 210 days nor more than
365 days before the expiration of the Basic Term or the preceding Renewal Term,
as the case may be. Such notice shall be irrevocable except that in the event
the Lessee gives such notice to the Lessor 240 or more days before the end of
the Basic Term or the Renewal Term then in effect, as the case may be, the
Lessee may revoke its election to extend this Lease within 15 days following the
determination of the Fair Market Rental Value of the Aircraft but in no event
later than 210 days prior to the end of the Basic Term or the preceding Renewal
Term, as the case may be. If the Lessee requests a determination of Fair Market
Rental Value at least 240 days before the expiration of the Basic Term or a
Renewal Term, as the case may be, the Lessor and the Lessee shall comply in a
timely manner with their respective obligations under the definition of "Fair
Market Rental Value" to allow any appraisal of Fair Market Rental Value to be
completed in sufficient time to permit the Lessee to exercise the revocation
right provided above. If no Specified Default shall have occurred and be
continuing on the date of such notice or on the date of the commencement of any
Renewal Term, then this Lease shall be extended for the additional period of
such Renewal Term as specified in such notice on the same conditions as provided
for herein. The Basic Rent payable per annum during any Fixed Renewal Term shall
be the lesser of (i) the then Fair Market Rental Value for the Aircraft and (ii)
Renewal Rental Rate identified on Exhibit B. The rental payable per annum during
any Fair Market Value Renewal Term shall be the then Fair Market Rental Value
for the Aircraft. Such rental during each Renewal Term shall be payable semi-
annually in arrears. The Termination Value of the Aircraft during each Renewal
Term shall be the Fair Market Sales Value for the Aircraft at the beginning of
such Renewal Term declining on a straight line basis to the projected Fair
Market Sales Value for the Aircraft at the end of such Renewal Term, but in both
cases determined prior to the commencement of such Renewal Term. Lessee's right
to renew this Lease at the end of the Basic Term is subject to the condition
precedent that the Owner Participant shall have agreed in writing with Lessee
not to demand payment of the Payment Amount (as defined in the Residual
Agreement) pursuant to Section 4(a) of the Residual Agreement within the period
specified therein (unless an Event of Default shall thereafter occur and be
continuing).

          (b)  Lessee's Purchase Options.
               -------------------------

               (i)   Rights to Purchase.
                     ------------------

          The Lessee shall have the right upon notice as provided herein to
purchase the Aircraft (A) on the EBO Date for a price equal to the EBO Amount;
(B) upon the termination of the Basic Term a price equal to the then Fair Market
Sales Value of the Aircraft; or (C) at the end of any Renewal Term for a price
equal to the then Fair Market Sales Value of the Aircraft in each case as long
as no Event of Default of the type referred to in Section 16(f), (g) or (h)
hereof shall have occurred and be continuing on the date of purchase. Upon the
payment by the Lessee of the purchase price for the Aircraft and the Basic Rent,
if any, payable in arrears on the date of purchase, together with all unpaid
Basic Rent, if any, payable before such date and all Supplemental Rent then due
and payable hereunder (including any Supplemental Rent payable in respect of
Make-Whole Amount), the Term shall end and the obligations of the Lessee to pay
Rent hereunder (except for Supplemental Rent obligations surviving pursuant to
Section 3(c), Articles 6 and 7 of the Participation Agreement or the Tax
Indemnity Agreement or which have otherwise accrued but not been paid as of the
date of such payment) shall cease, and the Lessor shall convey to the Lessee all
right, title and interest of the Lessor in and to the Aircraft on an "as-is,
where is" basis, without recourse or warranty except a warranty against Lessor's
Liens.

               (ii)  Option to Assume Equipment Notes.
                     --------------------------------

          In the event the Lessee elects to purchase the Aircraft pursuant to
clause (A) of Section 13(b)(i), the Lessee may, at its election, assume the
payment obligations of the Lessor with respect to such Equipment Notes as
contemplated by Section 5.10 of the Participation Agreement, in which case the
purchase price to be paid by the Lessee shall be reduced by an amount equal to
the principal of the Equipment Notes so assumed by the Lessee.

               (iii) Notice of Exercise of Option.
                     ----------------------------

          The Lessee's right to purchase provided for in clause (B) or (C) of
Section 13(b)(i) shall be exercised upon written notice to the Lessor not less
than 180 days nor more than 365 days before the applicable date of purchase
provided in such clause (B) or (C) as the case may be. Such notice shall be
irrevocable, except that where the purchase price is or may be measured by the
Fair Market Sales Value of the Aircraft the Lessee may revoke its exercise of an
option to purchase the Aircraft within 15 days following the determination of
such Fair Market Sales Value, but in no event later than 180 days prior to the
applicable date of purchase provided in such clause (B) or (C), as the case may
be. The Lessee's right to purchase provided for in clause (A) of Section
13(b)(i) shall be exercised upon written notice to the Lessor not less than 90
days nor more than 365 days before the EBO Date and shall be irrevocable when
given.

Section 14.    Voluntary Termination for Obsolescence.
               --------------------------------------

               (a)  Termination by Sale of Aircraft.
                    -------------------------------

               So long as no Specified Default shall have occurred and be
continuing, the Lessee shall have the right at its option five years or more
after commencement of the Basic Term on at least 180 days', but not more than
365 days, prior written notice (which notice shall be irrevocable, except as
provided below) to the Lessor and the Indenture Trustee, specifying a proposed
date of termination which shall be a Termination Date, to terminate this Lease
if the chief financial officer of the Lessee shall have certified in writing to
the Lessor that the Aircraft shall have become obsolete or shall be surplus to
the Lessee's equipment requirements. Subject to the Lessor's preemptive election
under Section 14(c), during the period following the giving of such notice of
termination until the Termination Date, the Lessee, as agent for the Lessor,
shall endeavor to sell the Aircraft "as is", without any warranty by the Lessor
or the Lessee except as to the Lessor's title, on behalf of the Lessor. If
Lessee receives any bid, it shall at least 10 Business Days prior to the
proposed day of sale, certify to Lessor in writing the amount and terms of such
bid, such proposed date of sale and the name and address of the potential buyer
(which shall not be Lessee or any Affiliate or any Person with whom Lessee or
any Affiliate has any arrangement or understanding for the future purchase,
lease, operation or use of the Aircraft). Lessor may also solicit bids directly
or through agents other than Lessee. So long as the Lessor has not exercised its
preemptive election under Section 14(c), the Lessee may, by notice to the Lessor
and the Indenture Trustee, withdraw its notice of termination at any time on or
before the date 10 days prior to the proposed Termination Date (unless such
withdrawal is due to the cancellation of the proposed purchase of the Aircraft
by the potential buyer in which event such notice may be given at any time on or
prior to the proposed Termination Date), and thereupon this Lease shall continue
in full force and effect. Withdrawal of notice of termination shall not exhaust
the Lessee's right to give a further notice of termination as provided herein;
provided that Lessee shall not be entitled to give more than two such notices
(excluding one notice of termination which has been withdrawn due to the
cancellation of the proposed purchase of the Aircraft by the potential buyer).
Unless the Lessee shall withdraw its notice of termination as stated above or
the Lessor shall have made a preemptive election to take possession of the
Aircraft in accordance with Section 14(c), on the Termination Date, or such
other date of sale as shall be consented to in writing by the Lessor and the
Lessee, which date shall thereafter be deemed the Termination Date, the Lessee
shall, upon payment in full of the amounts described in Section 14(b), deliver
the Airframe and Engines or engines installed thereon to the party which shall
have prior to such date submitted the highest bona fide cash bid to close such
sale and purchase of the same, in the same manner as if delivery were being made
to the Lessor pursuant to Section 12, and shall duly transfer to such party
title to any engines which are not Engines delivered with the Airframe in
accordance with the terms of Section 12. The Lessor shall, in "as-is, where-is"
condition, without recourse or warranty (except a warranty as to the absence of
Lessor's Liens), simultaneously therewith sell and convey title to the Airframe
and the Engines or engines conveyed to the Lessor as provided in Section 12 for
cash to such party and request that the Indenture Trustee release the Aircraft
from the Lien of the Indenture. Upon the sale of the Airframe and the Engines or
engines

                                     -45-
<PAGE>

conveyed to the Lessor as provided in Section 12 pursuant to this Section 14 and
receipt by the Lessor of all amounts referred to in Section 14(b), the Lessor
will transfer to the Lessee, in "as-is, where-is" condition, without recourse or
warranty (except a warranty as to the absence of Lessor's Liens), all right,
title and interest of the Lessor in and to any Engines constituting part of the
Aircraft but which were not delivered to the purchaser with the Airframe. The
Lessee shall pay all out of pocket expenses of the Lessor, Owner Participant,
Indenture Trustee and each Noteholder in connection with any termination or
proposed termination of this Lease except that Lessee shall not be responsible
for such expenses of the Lessor or the Owner Participant in the event the Lessor
exercises its preemptive election under Section 14(c) and thereafter fails to
perform its obligations under such Section.

          (b)  Payments Due Upon Sale of Aircraft.
               ----------------------------------

          The total selling price realized at any sale of the Airframe and
Engines or engines installed thereon in accordance with this Section 14 shall be
retained by the Lessor and, in addition, on the Termination Date, the Lessee
shall pay to the Lessor or, in the case of Supplemental Rent, to the Persons
entitled thereto, in immediately available funds, an amount equal to the sum of
(A) the excess, if any, of (x) the Termination Value as of the Termination Date,
over (y) the net proceeds of the sale of the Aircraft, plus (B) all unpaid
Supplemental Rent due on or before the Termination Date (including Make-Whole
Amount), plus (C) the arrears portion, if any, of Basic Rent payable on such
Termination Date, together with all unpaid Basic Rent, if any, payable before
the Termination Date, plus (D) the reasonable fees and expenses of the
Participants, the Indenture Trustee and Lessor in connection therewith, plus (E)
any sales, transfer or similar Taxes incurred on such sale.

          (c)  Preemptive Election by Lessor.
               -----------------------------

          Notwithstanding the foregoing provisions of this Section 14, the
Lessor may, not later than 90 days prior to the proposed Termination Date,
notify the Lessee of its preemptive election to take possession of the Aircraft,
which notice shall be accompanied by an irrevocable undertaking by the Lessor to
pay to the Indenture Trustee the amount required to pay in full (after giving
effect to any installment of Basic Rent due and payable on such date) the
aggregate unpaid principal amount of the outstanding Equipment Notes, together
with all accrued interest thereon and Make-Whole Amount, if any (without
releasing Lessee from its obligations under clause (B) of Section 14(b) in
respect of the payment of such amount). Upon payment by the Lessor of such
amount to the Indenture Trustee, and payment by the Lessee of all amounts
specified in this Section 14(c) to be paid by the Lessee on the Termination
Date, the Lessee shall have no obligation to pay Termination Value. On the
Termination Date, if the Lessor shall have paid such amount to the Indenture
Trustee, the Lessee shall deliver the Airframe and Engines or engines installed
thereon to the Lessor in accordance with Section 12 and shall pay all unpaid
Basic Rent, if any, payable before the Termination Date, together with the
arrears portion, if any, of Basic Rent due on such Termination Date, all unpaid
Supplemental Rent due on or before or after the Termination Date

                                     -46-
<PAGE>

(including Make-Whole Amount), and the Lessor shall transfer to the Lessee title
to any Engines constituting part of the Airframes but which were not then
installed on the Aircraft as provided in Section 12(b). If the Lessor, having
given notice of a preemptive election, shall fail to perform any of its
obligations pursuant to this Section 14(c) and as a result thereof this Lease
shall not be terminated on a proposed Termination Date, the Lessee may at its
option at any time thereafter submit a new termination notice but the Lessor may
only be entitled to exercise on one additional occasion its preemptive election
to retain the Aircraft upon a subsequent termination pursuant to this Section
14.

          (d)  Termination of Lease.
               --------------------

          Upon delivery by the Lessee of the Airframe and Engines or engines
installed thereon and payment by the Lessee of all amounts payable by the Lessee
under either Section 14(b) or 14(c), as the case may be, the obligations of the
Lessee to pay Rent (except for Supplemental Rent obligations surviving pursuant
to Section 3(c) and Articles 6 and 7 of the Participation Agreement or the Tax
Indemnity Agreement or which have otherwise accrued but not paid as of the
Termination Date) shall cease and the Term shall end.

          (e)  Effect of No Sale or Preemptive Delivery to Lessor.
               --------------------------------------------------

          If on the Termination Date no sale of the Aircraft shall have occurred
and the Lessee has not delivered the Aircraft to the Lessor pursuant to Section
14(c) or the Lessor shall fail to pay the amounts specified in Section 14(c)
upon exercise of its preemptive election, the Lessee's notice given pursuant to
Section 14(a) shall be deemed to be withdrawn as of such date and this Lease
shall continue in full force and effect, without prejudice, however, to any
claims the Lessee may have against any Person under the Participation Agreement
or otherwise if a failure to deliver the Aircraft to the Lessor pursuant to
Section 14(c) shall have been due to a failure of the Lessor to make the payment
by the Lessor provided for in such Section.

          (f)  No Duty on Part of Lessor.
               -------------------------

          Lessor shall be under no duty to solicit bids, to inquire into the
efforts of Lessee to obtain bids or otherwise to take any action in connection
with any such sale other than to cooperate with such efforts as Lessee may
reasonably request and to make the transfers described in Section 14(a).

 Section 15. Investment of Security Funds.
             ----------------------------

          Any monies paid to or retained by the Lessor which are required to be
paid to the Lessee or applied for the benefit of the Lessee (including, without
limitation, amounts payable to the Lessee under Sections 8 and 9), but which the
Lessor is entitled to hold under the terms hereof pending the occurrence of some
event or the performance of some act (including, without limitation,

                                     -47-
<PAGE>

the remedying of an Event of Default), shall, until paid to the Lessee or
applied as provided herein, be invested by the Lessor (or, if the Indenture
shall not have been discharged, the Indenture Trustee) from time to time at the
direction, risk and expense of the Lessee in Permitted Investments, subject, in
the case of investments by the Indenture Trustee to the terms of Section 3.07 of
the Indenture. There shall be promptly remitted to the Lessee any gain
(including interest received) realized as the result of any such investment (net
of any fees, commissions and other expenses, if any, incurred in connection with
such investment) unless a Specified Default shall have occurred and be
continuing, in which case such gains shall be held or applied in accordance with
the preceding sentence. The Lessee will promptly pay to the Indenture Trustee or
the Lessor, as the case may be, on demand, the amount of any loss realized as
the result of any such investment (together with any fees, commissions and other
expenses, if any, incurred in connection with such investment).

 Section 16. Events of Default.
             -----------------

          The following events shall constitute Events of Default (whether any
such event shall be voluntary or involuntary or come about or be effected by
operation of law or pursuant to or in compliance with any judgment, decree or
order of any court or any order, rule or regulation of any administrative or
governmental body) and each such Event of Default shall be deemed to exist and
continue so long as, but only so long as, it shall not have been remedied:

          (a)  The Lessee shall fail to make any payment of (i) Basic Rent,
     Termination Value or a payment required by clause (iii) of the second
     sentence of Section 3(c) when due and such failure shall continue for a
     period of ten (10) days or (ii) Supplemental Rent (other than Termination
     Value or the payment required by clause (iii) of the second sentence of
     Section 3(c)) within fifteen (15) days after receipt by the Lessee of a
     written demand therefor from the Lessor, the Indenture Trustee or a
     Majority in Interest of Noteholders, provided, that in the case of
                                          --------
     Supplemental Rent which constitutes an Excluded Payment, such demand shall
     only be effective for purposes of this paragraph (a) if sent by the Owner
     Participant or the Lessor and such failure shall not become an Event of
     Default until the Owner Participant shall have notified the Indenture
     Trustee that it has elected to treat such failure as an Event of Default;

          (b)  The Lessee shall fail to procure and maintain insurance required
     pursuant to Section 9 or such insurance shall be cancelled or lapse;
     provided that such lapse or cancellation shall not constitute an Event of
     --------
     Default until the earlier of (i) thirty (30) days after receipt by the
     Lessor or the Indenture Trustee of notice of such lapse or cancellation (or
     seven (7) days or such shorter time as may be standard in the industry with
     respect to war-risk coverage) or (ii) the date that such lapse or
     cancellation is effective as to the Lessor, the Owner Participant, the
     Indenture Trustee or any Noteholder;

          (c)  The Lessee shall operate the Aircraft after having received
     notice that the public liability insurance required by Section 9(a) has
     lapsed or has been cancelled;

                                     -48-

          (d)  The Lessee shall fail to perform or observe any other covenant or
     condition to be performed or observed by it hereunder or under any other
     Operative Agreement (other than the Tax Indemnity Agreement), and such
     failure shall continue unremedied for a period of thirty (30) days after
     delivery of notice of such failure from the Lessor, the Indenture Trustee
     or a Majority in Interest of Noteholders to the Lessee, unless such failure
     is curable and the Lessee shall, after the delivery of such notice, be
     diligently proceeding to correct such failure and shall in fact correct
     such failure within 150 days after delivery of such notice;

          (e)  Any representation or warranty made by the Lessee herein or in
     any Operative Agreement or in any document or certificate required to be
     delivered by the Lessee pursuant thereto (other than the Tax Indemnity
     Agreement) shall prove to have been incorrect in any material respect when
     made and shall remain material at the time in question and shall not be
     remedied within thirty (30) days after notice thereof has been given to the
     Lessee by the Lessor or the Indenture Trustee or a Majority in Interest of
     Noteholders, unless such incorrectness is curable and Lessee shall, after
     delivery of such notice, be diligently proceeding to correct such failure
     and shall in fact correct such failure within 150 days after the delivery
     of such notice;

          (f)  The Lessee shall consent to the appointment of or taking
     possession by a receiver, assignee, custodian, sequestrator, trustee or
     liquidator (or other similar official) of itself or of a substantial part
     of its property, or the Lessee shall fail or shall admit in writing its
     inability to pay its debts generally as they come due (as provided in 11
     U.S.C. (S) 303(h)(1)), or shall make a general assignment for the benefit
     of its creditors, or the Lessee shall file a voluntary petition in
     bankruptcy or a voluntary petition or answer seeking liquidation,
     reorganization or other relief with respect to itself or its debts under
     any applicable bankruptcy or insolvency or similar laws, as now or
     hereafter constituted or any other applicable Federal or State bankruptcy,
     insolvency or other similar law or shall consent to the entry of an order
     for relief in an involuntary case under any such law or the Lessee shall
     file an answer admitting the material allegations of a petition filed
     against the Lessee in any such proceeding, or otherwise seek relief under
     the provisions of any now existing or future Federal or State bankruptcy,
     insolvency or other similar law providing for the reorganization or
     winding-up of corporations, or providing for an agreement, composition,
     extension or adjustment with its creditors;

          (g)  An order, judgment or decree shall be entered in any proceeding
     by any court of competent jurisdiction appointing, without the consent of
     the Lessee, a receiver, trustee or liquidator of the Lessee or of any
     substantial part of its property, or any substantial part of the property
     of the Lessee shall be sequestered, and any such order, judgment, decree,
     appointment or sequestration shall remain in force undismissed, unstayed or
     unvacated for a period of sixty (60) days after the date of entry thereof;

                                     -49-
<PAGE>

          (h)  A petition against the Lessee in a proceeding under any
     applicable bankruptcy laws or other insolvency or similar laws as now or
     hereafter in effect shall be filed and shall not be withdrawn or dismissed
     within sixty (60) days thereafter, or, in the case the approval of such
     petition by a court of competent jurisdiction is required, the petition as
     filed or amended shall be approved by such a court as property filed and
     such approval shall not be withdrawn or the proceeding dismissed within
     sixty (60) days thereafter, or a decree or order for relief in respect of
     the Lessee shall be entered by a court of competent jurisdiction in an
     involuntary case under such bankruptcy, insolvency or similar laws, as now
     or hereafter constituted and such decree or order shall remain unstayed in
     effect for a period of sixty (60) days, or if, under the provisions of any
     law providing for reorganization or winding-up of corporations which may
     apply to the Lessee, any court of competent jurisdiction shall assume
     jurisdiction, custody or control of the Lessee or of any substantial part
     of its property and such jurisdiction, custody or control shall remain in
     force unrelinquished, unstayed or unterminated for a period of sixty (60)
     days;

          (i)  So long as the Indenture is in effect or, after foreclosure of
     the Lien of the Indenture, so long as the Indenture Trustee or its nominee
     holds title to the Aircraft, final judgment or judgments for the payment of
     money in excess of $5,000,000 (which is not covered by insurance) shall be
     outstanding against the Lessee for more than thirty (30) days from the date
     of its entry and has not been satisfied or discharged in full, vacated,

     that, so long as neither the Lessee nor an Affiliate of the Lessee is the
     Owner Participant, the event described in this Section 16(i) shall only

     the Indenture Trustee in writing that it agrees to treat such event as an
     Event of Default;

          (j)  So long as the Indenture is in effect or, after foreclosure of

     hereinafter defined) or contained in any instrument or agreement
     evidencing, securing or relating thereto, or any other event shall occur or
     condition exist, the effect of which default or other event or condition
     being that any outstanding Indebtedness in excess of $5,000,000 (or the
     equivalent in any foreign currency) has become payable prior to its stated
     maturity or due date (and such acceleration is not (i) promptly waived by

     under any lease, or (C) under any agreement whereby the Lessee guarantees
     the obligations of any other Person for borrowed money or under a lease by
     such Person, provided that, so long as neither the Lessee

                                     -50-
<PAGE>

     nor an Affiliate of the Lessee is the Owner Participant, the event
     described in this Section 16(j) shall only constitute an Event of Default
     if the Owner Participant shall have notified the Indenture Trustee in
     writing that it agrees to treat such event as an Event of Default;

          (k) Except if the Indenture is terminated in accordance with its
     terms, the Lien of the Indenture shall cease to be a valid first priority
     Lien (other than as a result of any Permitted Lien or as a result of any
     Indenture Default or Indenture Event of Default of the type referred to in
     Section 4.02(j) of the Indenture) on (i) the Indenture Estate (other than
     the Aircraft) and such condition shall continue for a period of ten (10)
     days after a Responsible Officer of the Lessee has actual knowledge of such
     condition or (ii) the Aircraft;

     benefits of Section 1110 of the Bankruptcy Code, and in either case such
     condition shall continue for a period of thirty (30) days; or

          (m) If, at any time after the Lien of the Indenture (and any other
     indenture or security agreement entered into in connection with a
     refinancing pursuant to Article 13 of the Participation Agreement) has been
     discharged in accordance with its terms or the Owner Participant has
     purchased the Equipment Notes (or the evidences of indebtedness under any
     such other indenture or security agreement), any "Event of Default" as
     defined in any Specified Lease shall occur and be continuing;

provided that, notwithstanding anything to the contrary contained in this Lease,
- --------
any failure of the Lessee to perform or observe any covenant, condition, or
agreement herein shall not constitute an Event of Default under clause (d) above
if such failure is caused solely by reason of an event referred to in the
definition of "Event of Loss" so long as the Lessee is continuing to comply with
               -------------
the applicable terms of Section 8.

 Section 17.   Remedies.
               --------

          Upon the occurrence of any Event of Default and at any time thereafter
so long as the same shall be continuing, the Lessor may, at its option, declare
this Lease to be in default by a notice to the Lessee (provided that this Lease
                                                       --------
shall be deemed to have been declared in default without the necessity of such
notice upon the occurrence of any Event of Default described in paragraph (f),
(g) or (h) of Section 16); and at any time thereafter so long as the Lessee
shall not have remedied all outstanding Events of Default, the Lessor may do,
and the Lessee shall comply with, one or more of the following with respect to
the Airframe and all or any part of the Engines, as the Lessor in its sole
discretion shall elect, to the extent permitted by, and subject to compliance
with any mandatory requirements of, Applicable Law then in effect; provided that

during any period the Aircraft is subject to the Civil Reserve Air Fleet Program
in accordance with the provisions of Section 5(b) and

in the possession of the United States government or an instrumentality or
agency thereof, the Lessor shall not, on account of any Event of Default, be
entitled to do any of the following in such manner as to limit the Lessee's
control under this Lease (or any sublessee's control under any sublease
permitted by the terms of this Lease) of any Airframe or any Engines, unless at
least 60 days' (or such lesser period, if any, as may then be applicable under
the Military Airlift Command Program of the United States Government) prior
notice of default hereunder shall have been given by the Lessor by registered or
certified mail to the Lessee (or any sublessee) with a copy addressed to the
Contracting Office Representative for the Military Airlift Command of the United

     the manner and condition required by, and otherwise in accordance with all
     of the provisions of, Section 12 as if the Airframe and such Engines were
     being returned at the end of the Term; or the Lessor, at its option, may
     cause public officials acting pursuant to judicial order obtained in
     summary proceedings or otherwise to enter upon the premises where the
     Airframe or any or all Engines are located or reasonably believed to be
     located and take immediate possession of and remove such Airframe or
     Engines, and the Lessee shall comply therewith, all without liability to
     the Lessor, the Indenture Trustee or the Noteholders for or by reason of
     such entry or taking possession or removal, whether for the restoration of
     damage to property caused by such taking possession or removal; or
     otherwise; and the Lessee shall promptly execute and deliver to the Lessor
     such instruments of title or other documents as the Lessor may deem
     necessary or advisable to enable the Lessor or its agent to obtain
     possession of the Airframe or the Engines, provided that if the Lessee
                                                --------
     shall for any reason fail to execute and deliver such instruments and
     documents after such request, the Lessor shall be entitled to a judgment
     for specific performance, conferring the right to immediate possession upon
     the Lessor and requiring the Lessee to execute and deliver such instruments
     and documents to the Lessor;

          (b) Sell or otherwise dispose of all or any part of the Aircraft, at
     public or private sale, whether or not the Lessor shall at the time have
     possession thereof, as the Lessor may determine, or hold, use, operate,
     lease to others or keep idle all or any part of the Aircraft, Airframe or
     any Engine as the Lessor, in its sole discretion, may determine, in any
     such case free and clear of any rights or claims of whatsoever kind of the
     Lessee except as hereinafter set forth in this Section 17 and without any
     duty to account to the Lessee with respect to such action or inaction or
     for any proceeds with respect thereto except to the extent required by
     paragraph (d) below in the event the Lessor elects to exercise its rights
     under said paragraph in lieu of its rights under paragraph (c) below;

          (c) Whether or not the Lessor shall have exercised, or shall
     thereafter at any time exercise, any of its rights under paragraph (a) or
     paragraph (b) above with respect to the Aircraft, the Lessor, by written
     notice to the Lessee specifying a payment date (which shall

<PAGE>

     be a Termination Date) not earlier than 10 days from the date of such
     notice, may require the Lessee to pay to the Lessor, and the Lessee shall
     pay to the Lessor, on the payment date specified in such notice, as
     liquidated damages for loss of a bargain and not as a penalty, any
     installment of Basic Rent due on or before such payment date plus an amount
     equal to the excess, if any, of (i) Termination Value for the Aircraft,
     determined as of such payment date over (ii) the Fair Market Sales Value
     for the Aircraft, computed as of such payment date, together with interest,
     to the extent permitted by Applicable Law, at the Past Due Rate on the
     amount of such excess, if any, from such payment date, to the date of
     actual payment of such amount; provided that, in any such instance in which
                                    -------------
     the Lessor is unable to repossess the Aircraft due to circumstances not
     relating to or caused by any Lessee Person and the Fair Market Sales Value
     thereof is deemed to be zero, upon receipt of any such payment under this
     clause (c) and all other amounts due hereunder, the Lessor shall convey,
     as-is, where-is, without recourse or warranty, other than a warranty
     against Lessor's Liens, to the Lessee all right, title and interest of the
     Lessor in and to the Airframe and Engines, and execute and deliver to the
     Lessee such bills of sale and other documents and instruments as the Lessee
     may reasonably request to evidence such conveyance;

          (d) In the event the Lessor, pursuant to paragraph (b) above, shall
     have sold the Aircraft upon reasonable notice to the Lessee, the Lessor in
     lieu of exercising its rights under paragraph (c) above with respect to the
     Aircraft, may, if it shall so elect, require the Lessee to pay the Lessor,
     and the Lessee shall pay to the Lessor, on the date of such sale, as
     liquidated damages for loss of a bargain and not as a penalty (in lieu of
     the Basic Rent due after the date on which such sale occurs but in addition
     to any installment of Basic Rent due on or up to the date on which such
     sale occurs), the amount of any deficiency of the net proceeds of such sale
     below the Termination Value of the Aircraft, determined as of the
     Termination Date immediately preceding the date of such sale, together with
     interest, to the extent permitted by Applicable Law, at the Past Due Rate
     on the amount of such deficiency from such Termination Date to the date of
     actual payment; and

          (e) (i) Rescind, cancel or terminate this Lease or (ii) exercise any
     other right or remedy which may be available under Applicable Law or
     proceed by appropriate court action to enforce the terms hereof or to
     recover damages (but in all events consistent with the liquidation of
     damages agreement set forth herein) for the breach hereof.

In addition, the Lessee shall be liable for any unpaid Supplemental Rent due
hereunder before or after any termination hereof (which obligations shall
survive following such termination), including all reasonable costs and expenses

Section 17, the Lessor or the Owner Participant may bid for and purchase such

addition to any other remedy referred to above or otherwise available to the
Lessor for the Event of Default at law or in equity; and the exercise or
beginning of exercise by the Lessor of any one or more of such remedies shall
not preclude the simultaneous or later exercise by the Lessor of any or all such
other remedies. No express or implied waiver by the Lessor of any Event of
Default hereunder shall in any way be, or be construed to be, a waiver of any
future or subsequent Event of Default.

herein the Lessor may, upon prior notice to the Lessee, itself make such payment
or perform or comply with such agreement, and the amount of such payment and the
amount of the reasonable expenses of the Lessor incurred in connection with such
payment or the performance of or compliance with such agreement, as the case may
be, together with interest thereon at the Past Due Rate, shall be deemed
Supplemental Rent, payable by the Lessee upon demand; provided that no such
                                                      --------
payment or performance by the Lessor shall be deemed to cure any Default or
Event of Default under this Lease or relieve the Lessee of any of its
obligations hereunder; provided further that nothing in this Section 18 shall be
                       --------
deemed to permit the Lessor to exercise any control over the operation or
maintenance of the Aircraft or any part thereof while it is being utilized in
the air transportation services  of the Lessee or any Permitted Sublessee
without the consent of the Lessee; provided further that the provisions of this
                                   --------
Section 18 shall not affect Lessor's right to exercise its remedies under
Section 17 upon the occurrence and continuance of an Event of Default.

Airframe, Engines and Parts as provided herein, and in any circumstances where
more than one construction of the terms and conditions of this Lease is
possible, a construction which would preserve such benefits shall control over
any construction which would not preserve such benefits or would render them
doubtful. To the extent consistent with the provisions of 11 U.S.C. (S) 1110 or
any analogous section of the Federal bankruptcy laws, as amended from time to
time, it is hereby expressly agreed and provided that, notwithstanding any other
provisions of the Federal bankruptcy laws, as amended from time to time, any
right of the Lessor to take possession of the Aircraft in compliance with the
provisions of this Lease shall not be affected by the provisions of 11 U.S.C.
(S) 362 or 363, as amended from time to time, or any

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

The portion of this Exhibit appearing below this text is intentionally deleted
from the FAA filing counterpart as the parties hereto deem it to contain
confidential information.

          A.   General Conditions Upon Return.  Unless purchased by Lessee
               ------------------------------
pursuant to Section 13 of the Lease, at the time of return of the Airframe upon
the termination of the Lease at the end of the Basic Term  or any Renewal Term
or pursuant to Section 14(c) or 17 of the Lease: (i) the Aircraft shall be
registered with the FAA in the name of the Lessor (except for a failure caused
by the Lessor being ineligible to be the registered owner of an aircraft
registered with the FAA), (ii the Aircraft shall have and be in compliance with
a currently valid standard certificate of airworthiness issued by the FAA and be
in compliance with Part 121 of the FAA Regulations (or successor regulations),
(ii the Aircraft shall be free and clear of all Liens (other than Lessor's
Liens) and rights of persons not party to any Operative Agreement under pooling,
interchange, overhaul, repair or similar agreements or arrangements, (iv the
Aircraft shall be in as good operating condition as when originally delivered to
Lessee, ordinary wear and tear excepted, and be fully equipped with two Engines
or other engines meeting the requirements of Replacement Engines, (v) the
Aircraft shall have all Lessee's and any Permitted Sublessee's exterior markings
removed or painted over and the areas where such markings were removed or
painted over refurbished as necessary to blend with adjacent areas, (vi the
Aircraft shall be in regular U.S. passenger configuration and with the same
number of seats as when delivered and the interior of the Aircraft shall be
clean in accordance with Lessee's customary standard for a "between flights"
cleaning, (vi the Aircraft will be in compliance with the maintenance provisions
of the Lease, and (vi the Aircraft shall have no outstanding airworthiness
directives issued by the FAA requiring terminating action by the date of return.
In the event the FAA shall issue any directive which would require improvements
to the Aircraft in order for the airworthiness certificate of the Aircraft to be
maintained in good standing, Lessee shall not apply for an extension of the date
of compliance with the directive as to the Aircraft to a date after the date of
return of the Aircraft pursuant to Section 12 of the Lease, unless it shall
previously or concurrently have applied for such an extension with respect to
all Canadair Regional Jet Series 200 ER aircraft in its fleet affected by such
directive.

          B.   Hours of Operation.  Unless purchased by Lessee pursuant to
               ------------------
Section 13 of the Lease, at the time of return of the Airframe upon the
termination of the Lease at the end of the Basic Term or any Renewal Term or
pursuant to Section 14(c) or 17 of the Lease:  (A) the Airframe shall have
remaining 25% of the hours or cycles of operation (whichever shall be
applicable) remaining until the Aircraft's next structural inspection (which
under the maintenance program in effect on the Delivery Date is the "C4"), all
as determined in accordance with the Lessee's (or any Permitted Sublessee's) FAA
approved maintenance program and (B) the number of hours or cycles of operation
(whichever shall be applicable under the maintenance program then in use with
respect to such Engine or engine) on each Engine or engine remaining until the
next scheduled life limited
<PAGE>

parts replacement, including hot section refurbishment, shall be at least 25% of
the hours or cycles (whichever shall be applicable) between such life limited
parts replacement, including hot section refurbishment, allowed under the
maintenance program then in use with respect to such Engine or engine which
shall have been approved by all necessary governmental approvals of the country
under the laws of which the Aircraft shall have then been registered.

          If (A) the Airframe does not meet the conditions specified in said
clause (A) above, Lessee shall pay or cause to be paid to Lessor a Dollar amount
computed by multiplying (I) the cost of performing the next structural
inspection of the type referred to in such clause (A) at a rate then charged by
an outside maintenance provider to Lessee for performing such work (where such
rate would also be available to Lessor) by (II) a fraction of which (x) the
numerator shall be the excess of (A) 25% of the hours of operation allowable for
the Airframe between such structural inspection over (B) the number of hours of
operation remaining on the Airframe to the next such structural inspection and
(y) the denominator shall be the number of hours of operation allowable between
such structural inspection.

          If any Engine or engine does not meet the conditions specified in
clause (B) above, Lessee shall pay or cause to be paid to Lessor, with respect
to any such Engine or engine, a Dollar amount computed by multiplying (aa) the
cost of performing the scheduled life limited parts replacement, including hot
section refurbishment, under the maintenance program then used by Lessee or any
Permitted Sublessee for an engine of the same model as such Engine at a rate
then charged by an outside maintenance provider to Lessee or such Permitted
Sublessee for performing such work (where such rate would also be available to
Lessor) by (cc) a fraction of which (x) the numerator shall be the excess of 25%
of the hours or cycles of operation (whichever is applicable) between life
limited part replacement allowable for an engine under the maintenance program
then in use with respect to such Engine or engine over the actual average number
of hours or cycles of operation on such Engine or engine remaining until the
next such scheduled life limited parts replacement, including hot section
refurbishment, and (y) the denominator shall be the number of hours or cycles
allowable between such scheduled life limited parts replacement, including hot
section refurbishment.

          PURCHASE AGREEMENT ASSIGNMENT [N583ML], dated as of August 10, 1999,
between MIDWAY AIRLINES CORPORATION, a Delaware corporation (herein called the
"Assignor") and FIRST UNION TRUST COMPANY, NATIONAL ASSOCIATION, a national
banking association, not in its individual capacity but solely as Owner Trustee
(herein called the "Assignee").

                             W I T N E S S E T H :
                             - - - - - - - - - -

          WHEREAS, the Assignor and Manufacturer are parties to the Purchase
Agreement, providing, among other things, for the manufacture by the
Manufacturer and the sale by the Manufacturer to the Assignor of certain
aircraft, engines and related equipment, including the Aircraft; and

          WHEREAS, the Assignee wishes to acquire the Aircraft from Bombardier
Capital Inc. (the "Seller") and the Assignor, on the terms and conditions
hereinafter set forth, wishes to assign to the Assignee certain of the
Assignor's rights and interests under the Purchase Agreement and the Assignee is
willing to accept such assignment, as hereinafter set forth; and

          WHEREAS, the Assignee intends to lease to the Assignor, and the
Assignor intends to lease from the Assignee, the Aircraft pursuant to the lease
agreement dated as of August 10, 1999 as the same may be amended, modified or
supplemented, between the Assignee, as lessor, and the Assignor, as lessee,
providing for the lease of the Aircraft (the "Lease").

          NOW, THEREFORE, in consideration of mutual covenants and agreements
herein contained and for other valuable consideration, receipt of which is
hereby acknowledged by the Assignor, the parties hereto agree as follows:

          1.   For all purposes of this Assignment, except as otherwise
expressly provided or unless the context otherwise requires, all terms used
herein in capitalized form and not otherwise defined herein, shall have the
meanings set forth in Appendix A to the Lease.

          2.   Subject to the terms and conditions of this Assignment, Assignor
does hereby sell, assign and convey to Assignee, its successors and permitted
assigns all of Assignor's rights in and to the Purchase Agreement as and to the
extent that the same relate to the Aircraft and the purchase and operation
thereof (except to the extent reserved below), including, without
<PAGE>

limitation, all warranty and indemnity provisions in the Purchase Agreement with
respect to the Aircraft and all claims thereunder in respect of the Aircraft,
and any and all rights of the Assignor to compel performance of the terms of the
Purchase Agreement in respect of the Aircraft, reserving to Assignor, however,
                                               --------- -- --------  -------
(i) all the Assignor's rights and interests in and to the Purchase Agreement to
the extent that each relates to aircraft other than the Aircraft and the
purchase and operation of such aircraft and to the extent that each relates to
any other matters not directly pertaining to the Aircraft, (ii) so long as the
Aircraft shall be subject to the Lease and no Event of Default shall have
occurred and be continuing and the Assignee or the Indenture Trustee (as
assignee of the Assignee) has not commenced the exercise remedies set forth in
Section 17 of the Lease, all rights of the Assignor to obtain services,
training, product support, promotional support, publications or demonstrations
and test flights pursuant to the Purchase Agreement, and (iii) with respect to
the Aircraft, all of Assignor's rights with respect to payments made by Assignor
pursuant to the Purchase Agreement (including without limitation any post-
delivery adjustments to the purchase price or amounts credited or to be credited
by the Manufacturer to Assignor). The foregoing assignment is subject to the
conditions that (i) concurrently with its execution, Assignee shall lease the
Aircraft to Assignor under the Lease and (ii) the written consent of the
Manufacturer to such assignment (the "Consent and Agreement") be provided in the
form of the Annex hereto.

          Unless an Event of Default shall have occurred and be continuing and
the Assignee or the Indenture Trustee (as assignee of the Assignee) shall have
commenced the exercise of remedies set forth in Section 17 of the Lease, and
subject to the provisions hereof, the Assignee shall and it does hereby
authorize the Assignor during the Term as Lessee under the Lease, to the
exclusion of the Assignee, to exercise in the Assignor's name, all rights and
powers of the "Buyer" under the Purchase Agreement and any warranty with respect
to the Aircraft made by the Manufacturer or any subcontractor or supplier, and
any other claims against the Manufacturer or any such subcontractor or supplier
with respect to the Aircraft, except that the Assignor may not enter into any
change, order or other amendment, modification or supplement to the Purchase
Agreement insofar as it relates to the Aircraft without the written consent of
the Assignee if such change, order, amendment, modification or supplement would
result in any recission, cancellation or termination of the Purchase Agreement
in respect to the Aircraft or otherwise materially adversely affect Assignee's
rights assigned hereunder. Any recovery or benefit resulting from enforcement of
any warranty, indemnity or claim shall be applied to remedy any defect in
respect of the Aircraft (or to reimburse the Assignor for its remedying of any
such defect) and the balance to be paid to the Assignor or the Assignee, as
their interests may appear. Assignee hereby accepts the foregoing assignment
subject to the terms hereof.

          3.   It is expressly agreed that, anything herein contained to the
contrary notwithstanding:  (a) the Assignor shall at all times remain liable to
the Manufacturer under the Purchase Agreement to perform all the duties and
obligations of the "Buyer" thereunder to the

                                       2
<PAGE>

same extent as if this Assignment had not been executed; (b) the exercise by the
Assignee of any of the rights assigned hereunder shall not release the Assignor
from any of its duties or obligations to the Manufacturer under the Purchase
Agreement except to the extent that such exercise by the Assignee shall
constitute performance of such duties and obligations; and (c) except as
provided herein, the Assignee, the Indenture Trustee, the Owner Participant, the
Noteholders or the Trust Company shall not have any obligation or liability
under the Purchase Agreement by reason of, or arising out of, this Assignment or
be obligated to perform any of the obligations or duties of the Assignor under
the Purchase Agreement or to make any payment or to make any inquiry as to the
sufficiency of any payment received by it or to present or file any claim or to
take any other action to collect or enforce any claim for any payment assignment
hereunder.

          Without in any way releasing the Assignor from any of its duties or
obligations under the Purchase Agreement, the Assignee confirms for the benefit
of the Manufacturer that, insofar as the provisions of the Purchase Agreement
relate to the Aircraft, in exercising any rights under the Purchase Agreement,
or in making any claim with respect to the Aircraft or other things (including
data, documents, training and services) delivered or to be delivered pursuant to
the Purchase Agreement, the terms and conditions of the Purchase Agreement shall
apply to, and be binding upon, the Assignee to the same extent as the Assignor.

          Nothing contained herein shall subject the Manufacturer to any
liability to which it would not otherwise be subject under the Purchase
Agreement or modify in any respect the contract rights of the Manufacturer under
the Purchase Agreement.

          At any time after an Event of Default shall have occurred and be
continuing and the Assignee shall have commenced the exercise of remedies set
forth in Section 17 of the Lease, the Assignee or the Indenture Trustee (as
assignee of the Assignee) and its successors and permitted assigns shall, to the
exclusion of the Assignor, be entitled to assert and enforce all rights and
claims of the "Buyer" under the Purchase Agreement assigned hereunder (including
the right to receive payments), and the Assignor agrees to cooperate with the
Assignee in asserting such rights and claims, and the Assignor does hereby
constitute, effective at any time after an Event of Default shall have occurred
and be continuing and the Assignee or the Indenture Trustee (as assignee of the
Assignee) shall have commenced the exercise of remedies set forth in Section 17
of the Lease, the Assignee, its successors and assigns, the Assignor's true and
lawful attorney, irrevocably, with full power (in the name of the Assignor or
otherwise) to ask, require, demand, receive, compound and give acquittance for
any and all monies and claims for monies due or to become due under, or arising
out of, the Purchase Agreement in respect of the Aircraft, to the extent that
the same have been expressly assigned by this Assignment and for such period as
the Assignee may exercise rights with respect thereto under this Assignment, to
endorse any checks or other instruments or orders in connection therewith and to
file any claims or take any action or

institute (or, if previously commenced, assume control of) any proceedings and
to obtain any recovery in connection therewith that the Assignee may deem to be
necessary or advisable with respect to such monies and claims for monies.

          For all purposes of this Assignment, the Manufacturer shall not be
deemed to have knowledge of and need not recognize nor take any action with
respect to the occurrence of any Event of Default, the declaration of an Event
of Default, or the exercise of remedies set forth in Section 17 of the Lease by
the Assignee, the discontinuance of any Event of Default or the Aircraft's
becoming no longer subject to the Lease or the Assignor's no longer being
entitled to possession of the Aircraft unless and until the Manufacturer shall
have received from the Assignee written notice thereof and the Manufacturer may
act with acquittance and conclusively rely upon any such notice.

          4.   The Assignor agrees that at any time and from time to time, upon
the written request of the Assignee, the Assignor, at its own cost and expense,
will promptly and duly execute and deliver any and all such further instruments
and documents and take such further action as the Assignee may reasonably
request in order to obtain the full benefits of this Assignment and of the
rights and powers herein granted.

Agreement is in full force and effect as to the Assignor and is enforceable
against the Assignor in accordance with its terms.  The Assignor further
represents and warrants that it has, with the authorized execution of the
Consent and Agreement, received all necessary consents to the assignment and
transfer contemplated herein.

          6.   The Assignor does hereby represent and warrant that it has not
assigned or pledged, and hereby covenants that it will not assign or pledge, so
long as this Assignment shall remain in effect, the whole or any part of the
rights hereby assigned or any of its rights with respect to the Aircraft under
the Purchase Agreement not assigned hereby, to anyone other than the Assignee.
The Assignor agrees that it will not enter into any agreement with the
Manufacturer that would materially and adversely affect the rights of the
parties under the Purchase Agreement insofar as it relates to the Aircraft or
waive any rights thereunder.

          7.   So long as the Aircraft is leased to the Assignor under the Lease
and unless an Event of Default shall have occurred and be continuing and the
Assignee or the Indenture Trustee (as assignee of the Assignee) shall have
commenced the exercise of remedies under Section 17 of the Lease, the Assignee
agrees that it will not enter into any agreement with the Manufacturer that
would amend, modify, rescind, cancel or terminate the Purchase Agreement insofar
as it relates to the Aircraft or waive any rights of Assignor thereunder without
the prior written consent of the Assignor.

"special guarantees" (as defined in the General Terms Agreement). The Assignee
hereby accepts such assignment.

          2.2.  Notwithstanding the foregoing, unless an Event of Default shall
have occurred and be continuing and the Assignee or the Indenture Trustee (as
assignee of the Assignee) shall have commenced the exercise of remedies set
forth in Section 17 of the Lease, the Assignee hereby authorizes the Assignor,
to exercise in the Assignor's name all rights in respect of the Warranties,
except that:  the Assignor may not enter into any change order or other
amendment, modification or supplement to the CF34 Warranty and/or the General
Terms Agreement in respect of any Warranties without the prior written consent

modification or supplement would result in any rescission, cancellation or
termination of the CF34 Warranty and/or the General Terms Agreement (to the
extent it relates to any applicable Warranties) or otherwise materially
adversely affect Assignee's rights assigned hereunder.

          2.3.  For all purposes of this Assignment, the Engine Manufacturer
shall not be deemed to have knowledge of and need not recognize the occurrence,
the continuance or the discontinuance of any Event of Default under the Lease,
or the exercise of remedies set forth in Section 17 of the Lease by the Assignee
or the Indenture Trustee (as assignee of the Assignee), unless and until the
Engine Manufacturer shall have received from the Assignee written notice thereof
addressed to the Engine Manufacturer's Manager of Small Commercial Engine
Contracts, G.E. Aircraft Engines, 1000 Western Avenue, Lynn, Massachusetts,
01910, U.S.A., and, in acting in acquittance with the CF34 Warranty, the General

the absence of a notice from the Assignee to the Engine Manufacturer that an
Event of Default has occurred and is continuing and the Assignee or the
Indenture Trustee (as assignee of the Assignee) has commenced the exercise of
remedies set forth in Section 17 of the Lease, resume the sole and exclusive
dealings with the Assignor authorized by this Clause 2 and by the Engine
Manufacturer's Consent and Agreement.

          2.4  The Assignment contained herein shall apply only to the Engines

has received written notice thereof.  The Engine Manufacturer shall not be
deemed to have knowledge of the replacement or substitution of an Engine due to
a Failure (as such term is defined in the CF34 Warranty, excluding normal wear,
tear and deterioration which can be restored by overhaul or repair), damage or
loss, until notified of such Failure, damage or loss.  Notice shall be sent to:

remaining Warranties, including but not limited to assignments for security

Manufacturer.

          3.4. Effective at any time after an Event of Default shall have
occurred and be continuing and the Assignee or the Indenture Trustee (as
assignee of the Assignee) shall have commenced the exercise of remedies set
forth in Section 17 of the Lease, the Assignor does hereby constitute the
Assignee, its successors and permitted assigns, the Assignor's true and lawful
attorney, irrevocably, with full power (in the name of the Assignor or
otherwise) to ask, require, demand, receive, compound and give acquittance for
any and all monies and claims for monies due or to become due under, or arising
out of, the General Terms Agreement in respect of such Engine, but only to the
extent that the same have been expressly assigned by this Assignment and, for
such period as the Assignee may exercise rights with respect thereto under this
Assignment, to endorse any checks or other instruments or orders in connection
therewith and to file any claims or take any action or institute (or, if
previously commenced, assume control of) any proceedings and to obtain any
recovery in connection therewith that the Assignee may deem to be necessary or
advisable with respect to such monies and claims for monies.

          3.5. So long as the Engine Manufacturer acts in good faith in

   signatory to Article 27 of the Convention on International Civil Aviation
   signed by the United States at Chicago on December 7, 1944, in which Airline
   is authorized to operate or in which another airline pursuant to lawful
   interchange, lease or similar arrangement, operates aircraft of Airline.
   This paragraph shall apply only to any Product manufactured to CFM's design.

B. Airline shall promptly notify CFM in writing and  give CFM authority,
   information and assistance (at CFM's expense) for the defense of any suit or
   proceeding.  In case such Product is held in such suit or proceeding to
   constitute infringement and the use of said Product is enjoined, CFM shall
   expeditiously, at its own expense and at its option, either (1) procure for
   Airline the right to continue using said Product; (2) replace same with
   satisfactory and noninfringing Product; or (3) modify same so it becomes
   satisfactory and noninfringing.  CFM shall not be responsible to Airline or
   to said other airline, for incidental or consequential damages, including,
   but not limited to, costs, expenses, liabilities and/or loss of profits
   resulting from loss of use under this Article IX.

The foregoing shall constitute the sole remedy of Airline and the sole liability

      accessories sold by the Vendor to the Airline on a direct purchase basis.
      In the event the controls and accessories suffer a Failure during the
      vendors warranty period, the Airline will submit a claim directly to the
      vendor in accordance with the terms and conditions of the Vendor's
      warranty.

   2. In the event a Controls and Accessories Vendor fails to provide a warranty
      at least as favorable as the CFM  engine warranty (for complete controls
      and accessories) or  parts warranty (for components thereof), or if
      provided, rejects a proper claim from the Airline, CFM will intercede on
      behalf of the Airline to

[*] CONFIDENTIAL TREATMENT REQUESTED

                                      B-6
<PAGE>

      resolve the claim with the vendor. In the event CFM is unable to resolve a
      proper claim with the vendor, CFM will honor a claim from the Airline
      under the provisions and limitations of CFM's Engine or Parts warranty, as
      applicable. Settlements under vendor back-up warranty will exclude credits
      for resultant damage to or from Controls and Accessories procured directly
      by Airline from Vendors.

G. Vendor Interface Warranty

   Should any CFM control or accessory, for which CFM is responsible, develop a
   problem due to its environment or interface with other controls and
   accessories or with the Engine, or any Part thereof, reverser, or equipment
   supplied by the aircraft manufacturer, CFM will be responsible for initiating
   corrective action.  If the vendor disclaims warranty responsibility for parts
   requiring replacement, CFM will apply the provisions of its  parts warranty
   to such part whether it was purchased originally from CFM or directly from
   the vendor.

H. Condition Monitoring Warranty
   -----------------------------

   1. CFM warrants CFM56 condition monitoring equipment, installed on Engines,

      [*] of any new Engine component due soley to data received from
      inoperative or malfunctioning condition monitoring equipment.

      Parts, in accordance with the provisions of its  Parts warranty  as set
      forth in paragraph B of Section II hereof.

   1.  CFM warrants to Airline that special tools and test equipment sold
       hereunder will, at the time of delivery, be free from defects in
       material, workmanship, and title.

   2.  If it appears within [*] from the date of shipment by CFM that any
       special tool or test equipment delivered hereunder does not meet the
       warranties specified in Paragraph 1. above and the Airline so notifies
       CFM in writing prior to the expiration of 30 days after the end of that
       [*], CFM shall, at its option, upon Airline's satisfactory
       demonstration that the special tools or test equipment was defective at
       the time of delivery, correct any such defects either by repairing the
       defective item or by making available a repair or replacement

[*] CONFIDENTIAL TREATMENT REQUESTED

<PAGE>

       item, Ex Works. At the request of CFM, Airline, at its expense, shall
       ship the defective item to a location on the Airline's system designated
       by CFM.

   3.  CFM reserves the right to make changes in design and add improvements
       without incurring any obligation (except as may exist under paragraph 1
       above) to make, at CFM's expense, the same on other special tools or test
       equipment previously sold by CFM.

   4.  This warranty is applicable only if the special tools and test equipment
       are operated, handled, used, maintained and repaired in accordance with
       CFM's then-current recommendations as stated in its manuals, bulletins or
       other written recommendations.

J. SPECIAL GUARANTEES

                  BASIS AND CONDITIONS FOR SPECIAL GUARANTEES
                  -------------------------------------------

A.    General Conditions
      ------------------

      The special guarantees offered under Exhibit B, Section II.J. above, have
      been developed specifically for Airline's new installed and spare
      Engines.  The values set forth in each Special guarantee are based upon a
      fleet of at least [*] new CFM56-7B20 powered  737 aircraft (the
      "Aircraft") to be delivered by December 31,2003 as more particularly
      described in Attachment A to Letter Agreement No. 1 and are based upon:

      1.   Airline procuring [*] spare Engines per the delivery schedule
           set forth in Attachment A to Letter Agreement No. 1;

      2.   Airline's Engines being identified and maintained separately from
           other operators' engines at the repair agency;

      3.   Airline's compliance with CFM's reasonably required warranty and
           guarantee administration procedures;

      4.   Airline operating the Aircraft (i) an average flight leg of [*]
           hours or greater, (ii) an average takeoff thrust derate of [*]
           percent or greater, and (iii) an average Aircraft utilization of
           [*] hours per year maximum.

      5.   Airline's compliance with CFM's recommended workscope guide and/or
           applicable engine manuals;

      6.   Written on-wing maintenance and performance restoration procedures
           which are recommended  by the manufacturer and are used to avoid
           unnecessary shop visits; and

      7.   Service bulletins agreed to between Airline and CFM are incorporated
           in a timely manner.

      Change in Aircraft or Engine quantity, Aircraft or Engine model, or
      Aircraft delivery schedule from that described above, or [*].

                                  (continued)

B.    Exclusions
      ----------

      The guarantees shall not apply to repairs that are due to negligence,
      accidents, improper operation, improper maintenance performed by a
      facility other than one owned by CFM or one of it's affiliated companies,
      or if the Engines are employed in power-back Aircraft operation.

C.    Administration
      --------------

      Unless otherwise stated these guarantees commence with delivery of
      Airline's first CFM56-7B powered 737 Aircraft and end [*] thereafter. The
      guarantees are not transferable without the written consent of CFM.

      [*]. If compensation becomes available to Airline under more than one
      specific guarantee, warranty or other engine program consideration,
      Airline will not receive duplicate compensation but will receive the
      compensation most beneficial to Airline under a single guarantee, warranty
      or other program consideration. Unless otherwise stated, the guarantee
      compensation will be in the form of credits for the purchase of spare
      Engines, Parts, and/or services from CFM, as elected by Airline.

D.    Miscellaneous
      -------------

      The Guarantees exclude Foreign Object Damage (FOD).

      The General Conditions described in Exhibit B of the CFM56 Product Support
      Plan included in the General Terms Agreement apply to these guarantees.

     General Electric Capital Corporation or one of its Affiliates, and General
     Electric Capital Corporation or one of its Affiliates desires to lease such

     applicable to each lease referred to in Recital (A) but only to the extent
     that the lease specifically incorporates the terms of the CTA; and

(C)  Each such lease transaction will be concluded only on the terms of an
     agreement entitled "Aircraft Lease Agreement," which together with this CTA
     (which will be incorporated into and become part of such Aircraft Lease
     Agreement), will constitute the lease for the applicable aircraft as
     identified therein;

     NOW, THEREFORE, for good and valuable consideration the receipt and

     Lessee hereby makes the representations and warranties set out in Section
     1.1 of Schedule 2 as of the date of execution of the Aircraft Lease
     Agreement and as of the Delivery Date, and Lessee understands that these
     statements must be true, both when the Aircraft Lease Agreement is executed

2.2  Lessor's Representations and Warranties

     Lessor hereby makes the representations and warranties set out in Section
     1.2 of Schedule 2 as of the date of execution of the Aircraft Lease
     Agreement and as of the Delivery Date, and Lessor understands that these
     statements must be true, both when the Aircraft Lease Agreement is executed
     and on the Delivery Date.

3.   CONDITIONS PRECEDENT

3.1  Conditions Precedent

     Lessor need not deliver and start the leasing of the Aircraft under the
     Lease unless each of the Conditions Precedent listed in Schedule 3 is
     satisfied.  Lessee need not accept and begin the

                                       2
<PAGE>

     leasing of the Aircraft under the Lease unless the conditions set forth in
     Section 4.3 have been satisfied.

4.   COMMENCEMENT

4.1  Leasing

     (a)  Lessor shall notify Lessee as soon as possible, but no later than at
          least thirty (30) days prior to the Scheduled Delivery Month, of the
          Scheduled Delivery Week and Lessor shall notify Lessee as soon as
          possible, but no later than at least one (1) week prior to the
          Scheduled Delivery Week, of the Scheduled Delivery Date.  Subject to
          Section 4.4, Lessor will lease the Aircraft to Lessee and Lessee will
          take the Aircraft on lease for the Term, which shall commence on the
          Delivery Date, and which shall be evidenced by Lessee's execution of
          Lease Supplement No. 1 and the Certificate of Technical Acceptance.

     (b)  If (i) Lessee is unwilling or unable to accept delivery of the
          Aircraft on the date on which Lessor tenders the Aircraft for Delivery
          to Lessee under and in accordance with Section 4.3(a), or Lessee fails
          to fulfil any Condition Precedent [(other than (x) a Condition
          Precedent requested by Lessor pursuant to Section 1.1(g) or 1.2(a)(xi)
          of Schedule 3 or (y) the Condition Precedent pursuant to Section
          1.2(b) of Schedule 3 but only to the extent the Lessee is unable to
          make the representations set forth in Sections 1.1(f) or (m) of
          Schedule 2 (the "Special Conditions"))] on or before such date and
          such Condition Precedent is not waived by Lessor, and (ii) the
          Aircraft meets the Delivery Condition Requirements, then the Rent
          Commencement Date for the Aircraft shall be deemed to have occurred on
          the date on which it is tendered by Lessor for Delivery in accordance
          with subclause (ii) of this Section 4.1(b), and Lessee shall be
          obligated to pay Rent for the Aircraft on and from such date
          regardless of whether the Delivery Date occurs or whether Lessee
          executes Lease Supplement No. 1 and the Certificate of Technical
          Acceptance, but Lessor shall have no obligation to deliver, and Lessee
          shall have no lease interest in the Aircraft or other right to
          possession of the Aircraft, unless and until Lessee fulfils all
          Conditions Precedent (which have not been waived by Lessor) and Lessee
          accepts delivery of the Aircraft as evidenced by its execution of
          Lease Supplement No. 1 and the Certificate of Technical Acceptance. In
          the event that any of the Special Conditions are not satisfied by
          Lessee or waived by the Lessor, neither the Delivery Date nor the Rent
          Commencement Date shall occur and (A) Lessee shall not be in breach of
          its obligation to accept the Aircraft hereunder and (B) Lessor shall
          have the right to terminate the Lease and shall not have any
          obligation to deliver the Aircraft and Lessee shall have no obligation
          to accept delivery of the Aircraft; provided, however, that if the
          Lease is terminated pursuant to clause (B) above due to the Lessee's
          inability to make the representations set forth in Section

                                       3
<PAGE>

          1.1(f) or (m) of Schedule 2, Lessee will on demand pay and indemnify
          Lessor for the Termination Costs.

     (c)  Lessee will be responsible for all risks associated with any loss of
          or damage to the Aircraft from the Delivery Date until the Return
          Occasion.

4.2  Procedure before Delivery

     Lessor and Lessee will follow the Pre-Delivery Procedure.

4.3  Delivery and Acceptance

     After the Pre-Delivery Procedure has been carried out and so long (x) as
     the Aircraft meets the Delivery Condition Requirements; (y) the
     representations and warranties of Lessor are correct in all material
     respects on such date and (z) the Warranty Agreements as defined in
     Schedule 1 hereto shall have been simultaneously executed and delivered by
     the parties thereto in connection with the acceptance of the Aircraft by
     Lessee:

     (a)  Lessor will offer to deliver the Aircraft to Lessee at the Delivery
          Location.

     (b)  Lessee will accept the Aircraft.  Lessee shall provide evidence of its
          acceptance by signing Lease Supplement No. 1 and the Certificate of
          Technical Acceptance for the Aircraft and delivering each such
          document to Lessor.

     (c)  Lessee's acceptance of the Aircraft shall be regarded as absolute,
          unconditional and irrevocable.

4.4  Delayed Delivery

     If an Unforeseen Event happens and, as a result, Delivery takes place after
     the Scheduled Delivery Date or does not happen:

     (a)  Lessor will not be responsible for any Losses that Lessee suffers
          resulting from such delay or non-delivery of the Aircraft;

     (b)  Lessee will not, except in the circumstances described in Section
          4.4(c), be entitled to terminate the Lease or to reject the Aircraft
          when it is offered for Delivery because of the delay.

     (c)  If the Aircraft has not been tendered for Delivery, in accordance with
          Section 4.3, by the Final Delivery Date, the Lessee may terminate the
          Lease by delivering notice to the other party within ten (10) days of
          such Final Delivery Date (and if such notice is not delivered within
          such ten (10) day period the Final Delivery Date will be deemed
          extended for one additional period of forty-five (45) days).  Upon the
          delivery of any such notice or automatically on the expiration of such
          forty-five (45) day period if no

                                       4
<PAGE>

          such notice has been delivered, all obligations of each party under
          the Lease will end on the date of such notice or the date of the
          expiration of such period, as the case may be, except that Lessor will
          repay to Lessee the Deposit (if any) or return to Lessee or cancel any
          Letter of Credit and Lessee will remain obligated under its indemnity
          set forth in Section 3 of Schedule 4.

     (d)  Lessee hereby agrees that its only right or remedy for a delay in
          delivery of the Aircraft as a result of an Unforeseen Event is the
          remedy set forth in Section 4.4(c) above and Lessee hereby waives any
          rights it may have under Section 2A-406 of the UCC or otherwise for
          any delay in delivery resulting from an Unforeseen Event.

5.   PAYMENTS

5.1  Deposit

     Lessee shall pay Lessor any Deposit that is specified in Section 3 of the
     Aircraft Lease Agreement.

5.2  Rental Periods

     The first Rental Period will start on the Rent Commencement Date and each
     subsequent Rental Period will start on the date immediately following the
     last day of the previous Rental Period.  Each Rental Period will end on the
     date immediately before the numerically corresponding day in the next
     month, except that:

     (a)  if there is no 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)  Time of Payment:  Lessee will pay to Lessor or its order Rent in
          advance on each Rent Date.  Lessor must receive value for the payment
          on each Rent Date.  If a Rental Period begins on a day which is not a
          Business Day, the Rent payable in respect of that Rental Period shall
          be paid on the Business Day immediately after that day, without
          interest.

     (b)  Amount:  The Rent payable during the Term shall be calculated in
          accordance with Schedule B of the Aircraft Lease Agreement.

                                       5

5.4  Supplemental Rent and Maintenance Adjustment

     (a)  Amount: If, under the Aircraft Lease Agreement, Lessee is required to
          pay Supplemental Rent or any Maintenance Adjustment, Lessee will pay
          (i) that Supplemental Rent, at the rates referred to in Section 3 of
          the Aircraft Lease Agreement, to Lessor in relation to each calendar
          month (or part of a month) of the Term, on the fifteenth (15th) day
          following the end of that calendar month (except that the last payment
          of Supplemental Rent during the Term shall be paid on the Expiry Date)
          or (ii)  any Maintenance Adjustment in the amounts and at the time
          specified in Section 3.3 of the Aircraft Lease Agreement.

     (b)  Adjustment:  The Supplemental Rent rates shall be adjusted after the
          Delivery Date not more frequently than annually (with any such
          adjustment having retrospective application as appropriate to reflect
          the provisions of paragraphs (ii) and (iii) below) based on the
          following:

          (i)  Annual Supplemental Rent Adjustment:  by the Annual Supplemental
               Rent Adjustment, compounded annually commencing on the first
               anniversary of the Delivery Date, by way of agreed inflation
               adjustment as set forth in Schedule B of the Aircraft Lease
               Agreement under the definition of Annual Supplemental Rent
               Adjustment.

          (ii) Hour to Cycle Ratio Adjustment: Lessor and Lessee acknowledge
               that the Engine Supplemental Rent Rate, Engine LLP Supplemental
               Rent Rate and Landing Gear Supplemental Rent Rate are based upon
               the assumption that the Aircraft will operate on an Assumed
               Ratio. If that assumption proves to be incorrect at any time
               during the Term based upon Lessee's actual operating experience
               during the previous twelve (12) months (on an aggregate twelve
               (12) month basis), and the hour to cycle ratio differs from the
               Assumed Ratio by more than 10% during such twelve (12) month
               period, Lessor shall have the right, upon written notice to
               Lessee, to adjust the Engine Supplemental Rent Rate, Engine LLP
               Supplemental Rent Rate and Landing Gear Supplemental Rent Rate
               (in the case of a decrease in the ratio below the Assumed Ratio)
               and Lessor, upon written request from Lessee, will make that
               adjustment (in the case of an increase in the ratio above the
               Assumed Ratio). Any adjustment shall be based on a table
               contained in the Aircraft Lease Agreement. Actual hour to cycle
               ratios may fall outside (either above or below) the ratios
               identified in that table. In that case, the actual values shall
               be determined by extrapolating the closest observed intervals in
               the table.

                                       6

               (iii)  Assumed Utilization Adjustment: Lessor and Lessee
                      acknowledge that any amounts of Airframe Supplemental Rent
                      and APU Supplemental Rent payable by Lessee are based upon
                      the assumption that the Aircraft will operate on an
                      Assumed Utilization. If that assumption proves to be
                      incorrect at any time during the Term based upon Lessee's
                      actual operating experience during the previous twelve
                      (12) months (on an aggregate twelve (12) month basis) such
                      that (A) the Assumed Utilization is 110% or greater than
                      Lessee's actual utilization of the Aircraft or (B) the
                      Assumed Utilization is 90% or less than Lessee's actual
                      utilization of the Aircraft. In the case of Clause (A) of
                      above, Lessor may make, and notify Lessee of, and in the
                      case of Clause (B) above, Lessor, upon written notice from
                      Lessee will make, such adjustment as Lessor determines is
                      necessary in its reasonable discretion to maintain the
                      rates of Airframe Supplemental Rent and APU Supplemental
                      Rent at levels which accurately reflect the costs
                      associated with obtaining relevant maintenance services at
                      prevailing industry rates.

               (iv)   Material Revision to Maintenance Program: If the Lessee's
                      Maintenance Program is materially revised, Lessor may
                      make, and notify Lessee of, such adjustment as Lessor
                      determines is necessary in its reasonable discretion to
                      maintain the Supplemental Rent at levels which accurately
                      reflect the costs associated with obtaining relevant
                      maintenance services at prevailing industry rates. Each
                      notice shall specify the revised Supplemental Rent rates
                      and the effective date of such revision and, absent
                      reasonable objection by Lessee, Lessee shall be bound by
                      it.

     (c)  Lessee acknowledges and agrees that Supplemental Rent is additional
          rent for the leasing of the Aircraft and not cash collateral or other
          collateral security for Lessee's maintenance obligations under the
          Lease.  Once paid all Supplemental Rent is the property of Lessor, it
          is not refundable to Lessee under any circumstances whatsoever and
          Lessee has no interest therein whatsoever.

5.5  Payments

     All payments by Lessee to Lessor under the Lease will be made for value on
     the due date (or if the due date is not a Business Day then the on the
     following Business Day) in Dollars and in immediately available funds by
     wire transfer to the Lessor's bank account as specified in Section 3 of the
     Aircraft Lease Agreement.

<PAGE>

5.6  Withholding and Tax Credit

     (a)  Withholding:  Lessee must not deduct any amount from any of its
          payments under the Lease, for or on account of any Taxes, unless it is
          required by law to do so, in which case Lessee must:

          (i)    deduct the minimum amount necessary to comply with the Law;

          (ii)   provided that the Lessor is a U.S. Person (as defined in
                 Section 7701 of the Internal Revenue Code) and Lessor has
                 provided to the Lessee, upon a request from Lessee and as
                 required by applicable law, any forms evidencing such status as
                 reasonably needed by Lessee to not withhold U.S. federal income
                 taxes, pay Lessor an extra amount so that Lessor receives a net
                 amount on the relevant payment date, that is equal to the
                 amount that it would have received if the reduction had not
                 been made. The amount of any such payment to Lessor must take
                 into account the tax treatment of that payment to Lessor
                 applying the principles of Section 5.10 such that Lessor shall
                 be in no worse position than it would have been if the
                 deduction had not applied in the first place;

          (iii)  pay the Tax to the relevant taxing authority according to the
                 relevant Law; and

          (iv)   obtain a receipt (if one is available) from the relevant taxing
                 authority and give it to Lessor.

     (b)  Tax Credit:  If Lessor, in good faith, determines that it has realized
          a tax benefit (by way of deduction, credit or otherwise) as a result
          of any payment for which Lessee is liable under Section 5.6(a) Lessor
          shall pay to Lessee as soon as practicable after the tax benefit has
          been realized (but not before Lessee has made all payments and
          indemnities to Lessor required under this Section), an amount which
          will ensure that (after taking account of the payment itself) Lessor
          is in no better and no worse position than it would have been if the
          deduction had not applied.

          Nothing in this Section 5.6(b) shall:

          (i)    interfere with the right of Lessor to arrange its tax affairs
                 in whatever manner it thinks fit; or

          (ii)   oblige Lessor to disclose any information relating to its Tax
                 affairs or any Tax computations; provided, that, if there is a
                 need for Lessee to verify any Tax computations hereunder,
                 Lessor will disclose such information to a nationally
                 recognized independent accounting firm selected by Lessee after
                 execution of

                                       8
<PAGE>

                 an appropriate confidentiality agreement restricting the
                 disclosure of such information.

5.7  Tax Indemnity

     (a)  General:

          (i)    Except as provided in Section 5.7(c), Lessee will on demand pay
                 and indemnify each Tax Indemnitee against any and all Taxes
                 levied or imposed against or upon or payable by such Tax
                 Indemnitee or Lessee and arising from the use or operation of
                 the Aircraft, the execution of the Lease or the payments made
                 under the Lease, including all Taxes relating or attributable
                 to Lessee, the Lease or the Aircraft, directly or indirectly,
                 in connection with the importation (only to the extent that the
                 importation arises out of the Lessee's use of the Aircraft),
                 exportation (only to the extent that the exportation arises out
                 of the Lessee's use of the Aircraft), registration, ownership
                 (but only to the extent relating to or attributable to or
                 arising as a result of the possession, operation, use or
                 maintenance of the Aircraft by Lessee), 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, indemnification
                 payment or other amounts arising therefrom, or the making of
                 any Equipment Change or the permanent replacement of any
                 Engine.

          (ii)   All Taxes indemnified pursuant to this Section 5.7(a) 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 copy of a receipt for Lessee's payment of
                 such Tax (including a certified copy if required by Lessor) 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 a Tax Indemnitee pursuant to
                 Section 5.7(a) shall be paid within thirty (30) days (but in no
                 event later than the date that the indemnified Tax is due)
                 after receipt of a written demand therefor from the relevant
                 Tax 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 Section 5.9 and Lessee shall have duly performed (and
                 shall continue to perform) all its obligations under Section
                 5.9 with

                                       9
<PAGE>

                 respect to such contest, then payment of the indemnity with
                 respect to such Tax under Section 5.7(a) shall, at Lessee's
                 election, be deferred until the date the contest has been
                 completed.

     (b)  Sales and Use Taxes:

          (i)    Except as provided in Section 5.7(c) below, without limiting
                 Section 5.7(a) above and without duplication, 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):

                 (y)  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 of
                      the Habitual Base or the State of Incorporation with
                      respect to the lease of the Aircraft to Lessee pursuant to
                      the Lease unless Lessee delivers to Lessor on or prior to
                      the Delivery Date such exemption certificate or other
                      document as may be required by applicable Law 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 Lease; and

                 (z)  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 Lease.

          (ii)   The parties will cooperate with each other 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 Lease.

          (iii)  The specific obligations with respect to sales and use taxes
                 set forth in this Section 5.7(b) are in addition to, and are
                 not in substitution for, Lessee's obligation to indemnify for
                 sales and use taxes pursuant to Section 5.7(a).

     (c)  Lessee is not required to indemnify Lessor under Section 5.7(a), (b)
          or (d) to the extent that the Tax arises because of:

          (i)    the willful misconduct or gross negligence of Lessor;

                                      10
<PAGE>

          (ii)   a Tax liability Lessor has which would have arisen even if the
                 Lease had not been entered into; or

          (iii)  a Tax liability charged on Lessor's gross or net income,
                 profits or gains by any Government Entity in the United States;
                 but excluding any Tax that is a Sales Tax or a Tax in the
                 nature of a Sales Tax; or

          (iv)   a Tax liability charged with respect to the period, or an event
                 occurring, (x) prior to the Delivery Date or (y) after the
                 Expiry.

     (d)  Lessee will also indemnify each Tax Indemnitee, on an After-Tax Basis,
          as set forth in that Part of Schedule B of the Aircraft Lease
          Agreement entitled "Special Tax Indemnity" and the provisions of
          Section 5.9 (Tax Contest and Information) shall apply thereto.

5.8  [INTENTIONALLY DELETED]

5.9  Tax Contest and Information

     (a)  If any Tax Indemnitee receives a written claim for any Tax for which
          Lessee would be required to pay an indemnity pursuant to Section 5.7,
          Lessor 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 Section 5.7.  If requested by
          Lessee in writing promptly after receipt of Lessor's notice, Lessor
          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.  Lessor shall determine the method of any
          contest conducted by Lessor except for any contest involving only
          taxes (other than income taxes) of the Tax Indemnitee for which the
          Tax Indemnitee is indemnified under this Agreement ("Severable Taxes")
          and (in good faith consultation with Lessee) control the conduct
          thereof.  Lessee shall determine the method of any contest conducted
          by Lessee and any contest involving Severable Taxes and (in good faith
          consultation with Lessor) control the conduct thereof.  Lessee shall
          pay in full all payments of Rent and other amounts payable pursuant to
          the Lease, without reduction for or on account of any Tax, while such
          contest is continuing.  Lessor shall not be required to contest, or to
          continue to contest, a claim for Taxes under this Section 5.9 if (x)
          such contest would result in a risk of criminal penalties or a
          material risk of a sale, forfeiture or loss of (including loss of
          use), or the imposition of a Lien (other than a Permitted Lien) on,
          the Aircraft, or (y)

                                      11
<PAGE>

          Lessee shall not have furnished an opinion of independent tax counsel
          selected by Lessor and reasonably satisfactory to Lessee, that a
          reasonable basis exists for such contest, or (z) a Default shall be
          continuing (unless Lessee shall have provided security reasonably
          satisfactory to Lessor securing Lessee's performance of its
          obligations under this Section 5.9). If Lessor contests any claim for
          Taxes by making a payment and seeking a refund thereof, then Lessee
          shall advance to Lessor, on an interest-free basis, an amount equal to
          the Taxes to be paid by Lessor in connection with the contest and
          shall indemnify Lessor on an After-Tax Basis for any adverse tax
          consequences to Lessor of such interest-free advance. Upon the final
          determination of any contest pursuant to this Section 5.9 in respect
          of any Taxes for which Lessee shall have made an advance to Lessor 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 Lessor under this
          Section 5.9 and Lessor'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 Lessor obtains a refund or reimbursement of all or any part of any
          Taxes for which a full indemnity was paid by Lessee, Lessor shall pay
          Lessee the amount of such refund or reimbursement, reduced by any
          Taxes imposed on Lessor on receipt or accrual of such refund or
          reimbursement and increased by any Taxes saved by Lessor by reason of
          the deductibility of such payment by Lessor.  If, in addition to such
          refund or reimbursement, Lessor receives an amount of interest on such
          refund or reimbursement, Lessor shall pay to Lessee the portion of
          such interest which is fairly attributable to such refund, reduced by
          any Taxes imposed on Lessor on receipt or accrual of such interest and
          increased by any Taxes saved by reason of the deductibility of such
          payment by Lessor.  Lessor shall not be required to make any payment
          to Lessee pursuant to this Section 5.9 while a Default shall have
          occurred and be continuing.

     (c)  Lessor in its sole discretion (by written notice to Lessee) may waive
          its rights to indemnification pursuant to Section 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 Lessor for the Taxes that are the subject of
          such claim.  If Lessor agrees to a settlement of any contest conducted
          pursuant to this Section 5.9 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 Section 5.7 with respect to the Tax liability accepted
          in such settlement.

                                      12
<PAGE>

     (d)  Information:

          (i)    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
                 or any other Tax Indemnitee under the Lease, Lessee will
                 complete the same and, on request, supply a copy of the report
                 or return to Lessor.

          (ii)   If any report, return or statement is required to be made by
                 Lessor or any other Tax Indemnitee with respect to any Tax for
                 which there is an indemnity obligation of Lessee under the
                 Lease, Lessee will use reasonable efforts, to the extent that
                 Lessee has actual knowledge thereof, to promptly notify Lessor
                 of the requirement, and will:

                 (y)  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
                      or any other Tax Indemnitee intends to prepare and file),
                      prepare such return in such manner as will show Lessor as
                      lessor of the Aircraft and 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

                 (z)  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.

          (iii)  Lessee will provide such information and documents as Lessor
                 may reasonably request to enable Lessor or any other Tax
                 Indemnitee to comply with its tax filing, audit and litigation
                 obligations.

5.10  Indemnity Payments - After-Tax Basis

      The amount of any payment made under Section 5.7 (Tax Indemnity)
      (including Section 5.7(d)), Section 5.21 (Expenses) or Section 10
      (Indemnity) to or for the benefit of any Indemnitee, 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 Section 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, (ii) United States state and local income tax and (iii) income taxes
      (if any) imposed by countries outside the United States at the actual
      rates imposed on the relevant Indemnitee on the payments and determined
      after taking into account the deductibility by such Indemnitee of

                                      13
<PAGE>

     (or other Tax benefit accruing to such Indemnitee) any such Tax (plus
     interest and penalties) or Expense, each at the rates assumed above.

5.11 Lessor Obligations Following Expiry Date

     Within 91 days after or, if Lessor is reasonably satisfied that there is no
     material risk that any payment made by Lessee pursuant to the Lease could
     be avoided as a preference, promptly after:

     (a)  redelivery of the Aircraft to Lessor in accordance with and in the
          condition required by the Lease; or

     (b)  payment to Lessor of the Agreed Value following an Event of Loss after
          the Delivery Date;

     or in each case such later time as Lessor is reasonably satisfied that
     Lessee has irrevocably paid to Lessor all amounts which may then be
     outstanding under the Lease and the Other Agreement:

          (i)    Lessor will pay to Lessee the balance of the Deposit (if any)
                 including any interest accrued thereon in accordance with the
                 provisions of this Agreement and the Aircraft Lease Agreement;

          (ii)   Lessor will pay to Lessee the amount of any Rent received in
                 respect of any period falling after the date of redelivery of
                 the Aircraft or payment of the Agreed Value, as the case may
                 be; and

          (iii)  Lessor will return to Lessee or cancel any Letter of Credit.

5.12 Net Lease

The Lease is a net lease.  The Lessee's obligation to pay Rent and to perform
all of its other obligations under the Lease is absolute and unconditional no
matter what happens and no matter how fundamental or unforeseen the event,
including any of the following: (a) any right of set-off, counterclaim,
recoupment, defense or other right which either party to the Lease may have
against the other (including any right of reimbursement) or which Lessee may
have against the Manufacturer, any manufacturer or seller of or any Person
providing services with respect to the Aircraft, any Engine or any Part or any
other Person, for any reason whatsoever; (b) any unavailability of the Aircraft
for any reason, including 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 (whether or not the same would, but for
this provision, result in the termination of the Lease by operation of law); (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

                                      14
<PAGE>

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,
Lessee or any other Person; (e) any invalidity or unenforceability or lack of
due authorization of, or other defect in, the Lease; (f) any Security Interests
or Taxes; and/or (g) any other cause or circumstance which but for this
provision would or might otherwise have the effect of terminating or in any way
affecting any obligation of Lessee under the Lease. Lessee acknowledges and
agrees that it has used its own judgement in selecting the Aircraft, and has not
relied on Lessor or on any information supplied by Lessor, that Lessor is not a
manufacturer of or dealer in aircraft and that Lessor has all of the rights and
benefits of a lessor under a lease to which Section 2A-407 of the UCC applies as
provided in such Section 2A-407.

Except as expressly set forth elsewhere in the Lease, Lessee hereby waives, to
the extent permitted by applicable Law, any and all right which it may now have
or which at any time hereafter may be conferred upon it, by statute or
otherwise, to terminate, abate, cancel, quit, reduce, defer, suspend or
surrender the Lease or the Aircraft or any obligation imposed upon Lessee under
the Lease (including payment of Rent or Supplemental Rent).

Each payment of Rent or Supplemental Rent made by Lessee shall be final.  Lessee
will not seek to recover all or any part of any payment of Rent or Supplemental
Rent for any reason whatsoever except manifest error, in which case Lessor shall
promptly make payment to Lessee.

If for any reason whatsoever the Lease shall be terminated in whole or in part
by operation of Law, except as specifically provided in the Lease, to the extent
permitted by applicable Law Lessee waives all rights (if any) to any termination
or diminution in its Rent or Supplemental Rent obligations hereunder and
nonetheless agrees to pay to Lessor an amount equal to each Rent and
Supplemental Rent payment at the time such payments would have become due and
payable in accordance with the terms thereof had the Lease not been terminated
in whole or in part and so long as such payments are made and all other terms
and conditions hereof are complied with by Lessee, Lessor and Lessee will deem
the Lease to remain in full force and effect.

Nothing in this Section 5.12 will be construed to limit Lessee's right to
institute separate legal proceedings against Lessor in the event of Lessor's
breach of the Lease subject to Sections 7.1 and 16.3 of this CTA, or to limit
Lessee's rights and remedies against any other person.

5.13 Further Provisions regarding Deposit

     (a)  If, under the Lease, Lessee is required to pay a Deposit, Lessee
          hereby grants a security interest in the Deposit to Lessor and the
          remaining provisions of this Section shall apply.  Lessee agrees that
          Lessor shall be entitled to commingle the Deposit with Lessor's
          general or other funds, Lessor will have no obligation to pay any
          interest thereon (except as Lessor may otherwise specifically agree)
          and Lessor will not hold

                                      15
<PAGE>

          any such funds as agent or in trust for Lessee or in any similar
          fiduciary capacity. In this regard, Lessee acknowledges and agrees
          that it is not located in the State of New York within the meaning of
          Section 7-101 1-c. (b) of the New York General Obligations Law and,
          therefore, the requirements of Section 7-101 of the New York General
          Obligations Law to the effect that Lessor hold the Deposit in a
          separate, interest bearing account do not apply.

     (b)  If an Event of Default shall have occurred and be continuing under the
          Lease or the Other Agreement, in addition to all rights and remedies
          accorded to Lessor elsewhere in the Lease or under Law in respect of
          the Deposit, Lessor may immediately or at any time thereafter, without
          prior notice to Lessee, apply all or part of the Deposit in or towards
          the payment or discharge of any matured obligation owed by Lessee or
          any Affiliate of Lessee under the Lease or the Other Agreement, in
          such order as Lessor sees fit, and/or exercise any of the rights of
          set-off described in Section 5.20 against all or part of the Deposit.

     (c)  If Lessor exercises the rights described in Section 5.13(b) above,
          Lessee shall, following a demand in writing from Lessor, immediately
          restore the Deposit to the level at which it stood immediately prior
          to such exercise.

5.14 Letter of Credit

     (a)  If, under the Lease, Lessee is required or elects to provide Lessor
          with a Letter of Credit, the provisions of this Section shall apply.
          Any Letter of Credit provided by Lessee to Lessor will be issued and
          payable by Wachovia Bank N.A. or another bank acceptable to Lessor in
          its sole and absolute discretion and in form and substance acceptable
          to Lessor in its sole and absolute discretion and will be issued as
          security for all payment obligations of Lessee to Lessor under the
          Lease and each Other Agreement (including any and all Losses suffered
          or incurred by Lessor), which shall remain in full force and effect
          and may be drawn down by Lessor upon demand at any time or times
          following the occurrence of an Event of Default until the Required LC
          Expiry Date.

     (b)  With the prior written consent of Lessor, the Letter of Credit may
          have a validity period or periods ending prior to the Required LC
          Expiry Date, provided that (i) the Letter of Credit shall, in each
          case, be renewed and delivered to Lessor not later than thirty (30)
          days prior to its expiry; and (ii) a Letter of Credit shall remain in
          force at all times up to the Required LC Expiry Date.

     (c)  If at any time during the Term, Lessor determines in its sole and
          absolute discretion that the current issuing or confirming bank for
          the Letter of Credit is no longer an acceptable issuing or confirming
          bank (whether by virtue of a material adverse change in its financial
          condition or for any other reason) Lessee shall promptly procure that
          the Letter of Credit is replaced by a Letter of Credit issued by
          another bank acceptable to Lessor in

                                      16
<PAGE>

          its sole and absolute discretion and (if requested by Lessor in its
          sole and absolute discretion) that such replacement Letter of Credit
          is confirmed by another bank acceptable to Lessor in its sole and
          absolute discretion.

     (d)  If Lessor makes a drawing under the Letter of Credit, Lessee shall,
          following a demand in writing by Lessor, immediately procure that the
          maximum amount available for drawing under the Letter of Credit is
          restored to the level at which it stood immediately prior to such
          drawing.

5.15 [INTENTIONALLY OMITTED]

5.16 Late Payment Interest

     (a)  If Lessee fails to pay any amount payable under the Lease on the due
          date, Lessee will pay on demand from time to time to Lessor interest
          (both before and after judgement) on that amount, from the due date to
          the date of payment in full by Lessee to Lessor, at the Interest Rate.
          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.

5.17 Currency

     (a)  Except for Losses and expenses suffered or incurred by Lessor, which
          shall be payable by Lessee to Lessor in the currency and in the amount
          in which such Loss is suffered or incurred, all amounts payable to
          Lessor under the Lease shall be payable in Dollars in New York and
          payment in Dollars in New York is of the essence.  Lessee must
          indemnify Lessor against any Loss Lessor suffers if:

          (i)  Lessor receives an amount relating to Lessee's obligations in a
               different currency from that in which payments should be made
               under the Lease; or

          (ii) Lessee pays a judgment or claim in a different currency from that
               in which payments should be made under the Lease.

     (b)  Lessee relinquishes any right to pay any amount under the Lease in a
          currency which is different from the currency provided in the Lease.
          Notwithstanding any such receipt, judgment or claim described in
          Section 5.17(a), Lessee shall have a separate obligation to pay, and
          Lessor shall have a separate claim against Lessee for, amounts to be
          indemnified by Lessee under this Section 5.17.

5.18 Certificates

     Except where expressly provided in the Lease, any certificate or
     determination by Lessor as to any rate of interest or as to any other
     amount payable under the Lease will, in the absence of manifest error, be
     presumed to be correct.

                                      17
<PAGE>

5.19 Appropriation

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

5.20 Set-off

     (a)  In this sub-clause, references to Lessee will also include Lessee's
          Subsidiaries.

     (b)  Lessor may, without notice, set-off any obligations owed by Lessee
          under the Lease or the Other Agreement against any obligation Lessor
          or any Affiliate owes Lessee under the Lease or the Other Agreement,
          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.  If the
     amount of an obligation is unknown, Lessor may estimate the amount.  Any
     difference between the estimated obligation and the actual obligation will
     be paid by either Lessor or Lessee, as appropriate, when the amount becomes
     known. Lessee shall not set-off any obligations owed by Lessor against any
     obligation Lessee owes Lessor under the Lease or the Other Agreement.

5.21 Expenses

     Whether or not the Aircraft is delivered to Lessee (unless delivery does
     not occur due to a breach by Lessor or due to Lessee's exercise of its
     rights under Section 4.4(c)), Lessee will pay to Lessor on demand all
     reasonable expenses (including all legal fees and expenses and the fees and
     expenses of other professional advisers) that the Lessor has to pay:

     (a)  to deal with any amendments, extensions, consents or waivers that are
          requested by Lessee (specifically excluding any expenses incurred by
          Lessor or any Affiliate in connection with any change in the ownership
          or financing of the Aircraft, including as contemplated by Section
          14.2) or to deal with any replacement of any Engine or Part;

     (b)  for FAA counsel and for assistance in perfecting the Lease in the
          State of Registry and the State of Incorporation (and any other
          appropriate place); and

     (c)  in connection with, the enforcement or preservation of any of Lessor's
          rights under the Lease (including under Section 10) or in respect of
          the repossession of any Aircraft.

     All amounts payable pursuant to this Section 5.21 will be paid in the
     currency in which they are incurred by Lessor.

                                      18

6.   MANUFACTURER'S WARRANTIES

     (a)  So long as no Significant Default has occurred which is continuing,
          Lessor shall make available to Lessee during the Term the benefit of
          all manufacturer's warranties in relation to the repair or remedy of
          any defect in the Aircraft (including compensation for loss of use of
          the Aircraft) to the extent that it is permitted to do so.  Lessee
          will give Lessor prompt written notice of any warranty claim which is
          settled with Lessee on the basis of a cash payment.

     (b)  If a Significant Default has occurred and is continuing Lessor may
          immediately recover from Lessee the proceeds of any warranty claims
          previously paid to Lessee to the extent that such claims relate to any
          defect in the Aircraft not fully and completely rectified by Lessee
          before such Significant Default and Lessor may (so long as such
          Significant Default is continuing):

          (i)  if Lessor has commenced the exercise of its remedies under
               Section 13.2 or the Aircraft has been returned pursuant to
               Section 12, retain for its own account any such proceeds
               previously paid to Lessor which would have been remitted to
               Lessee under this Section 6 in the absence of such Significant
               Default; and

          (ii) cause any proceeds of any pending claims to be paid to Lessor,
               rather than Lessee.

     (c)  Lessee will take all steps as are reasonably requested by Lessor at
          the end of the Term to ensure that the benefit of any warranties
          relating to the Aircraft which have not expired is vested in Lessor.

     (d)  To the extent that any of the provisions of Section 6(a), 6(b) or 6(c)
          above is inconsistent with the assignment of warranties contained in
          any of the Warranty Agreements, such agreements shall be controlling.

7.   LESSOR'S COVENANTS

7.1  Quiet Enjoyment

     So long as no Event of Default has occurred and is continuing, Lessor will
     not interfere with Lessee's right to quiet use and possession of the
     Aircraft during the Term.  Exercise by Lessor of its rights of inspection
     or other rights provided to it under the Lease in the absence of an Event
     of Default shall not be considered to be a breach of the foregoing
     covenant.  Lessee agrees that its only right with respect to a default by
     Lessor under the Lease is to make a claim against Lessor for actual damages
     resulting directly therefrom and in any event subject to Section 16.3
     hereof, and Lessee hereby waives any and all other rights or remedies it
     may

                                      19
<PAGE>

     have solely by reason of Section 2A-211 of the UCC (without limiting
     however the obligation of the Lessor under the first sentence of this
     paragraph) or Sections 2A-508 through 2A-522 of the UCC or otherwise.
     During the Term, Lessor will take such action as may be necessary to
     discharge any Lessor Lien of the type referred to in clause (ii) of the
     definition of "Lessor Lien" which would result in a breach of this Section
     7.1; provided that Lessor will not be required to discharge any such Lessor
     Lien which arises from a claim being contested by Lessor (or its successors
     or assigns) in good faith and by appropriate proceedings so long as such
     proceedings do not involve any material risk of the sale, forfeiture or
     loss (including loss of use) of the Aircraft.

7.2  Maintenance Contributions

     If, under the Aircraft Lease Agreement for the Aircraft, Lessee is required
     to pay Supplemental Rent, then provided no Event of Default has occurred
     and is continuing, Lessor will pay (as a separate and independent
     obligation and not as a return of Supplemental Rent) the following amounts
     to Lessee by way of contribution to the cost of maintenance of the
     Aircraft, UPON RECEIPT BY LESSOR, WITHIN NINE (9) MONTHS AFTER COMPLETION
     OF SUCH MAINTENANCE AND IN ANY EVENT NO LATER THAN NINE (9) MONTHS AFTER
     THE EXPIRY DATE, of an invoice and supporting documentation reasonably
     satisfactory to Lessor evidencing performance of the following work by the
     Maintenance Performer:

          (i)   Airframe:  With respect to the Airframe, the completion, in
                accordance with Section 8.10, of the Airframe Structural Check,
                the lesser of (aa) the amount of that invoice and (bb) an amount
                equal to the aggregate amount of the Airframe Supplemental Rent
                paid under the Lease at the date such work starts less the
                aggregate amount previously paid by Lessor under this sub-
                clause;

          (ii)  Engine Life-Limited Parts: With respect to life-limited Parts
                within any Engine, the performance, in accordance with Section
                8.10, of any replacement or repair of those Parts ("Engine LLP
                Replacement"), the lesser of (x) the amount of that invoice and
                (y) an amount equal to the aggregate amount of the Engine LLP
                Supplemental Rent paid in respect of that Engine under the Lease
                at the date such work starts less the aggregate amount
                previously paid in respect of that Engine by Lessor under this
                sub-clause;

          (iii) Engine Refurbishment: With respect to any Engine, the
                performance, in accordance with Section 8.10, of Engine
                Refurbishment in respect of that Engine the lesser of (x) the
                amount of that invoice and (y) an amount equal to the aggregate
                amount of the Engine Supplemental Rent paid under the Lease in

                                      20
<PAGE>

                respect of that Engine at the date such work starts less the
                aggregate amount previously paid in respect of that Engine by
                Lessor under this sub-clause;

          (iv)  APU: With respect to the APU, the performance, in accordance
                with Section 8.10, of all shop visits requiring APU removal and
                disassembly, the lesser of (x) the amount of that invoice and
                (y) an amount equal to the aggregate amount of the APU
                Supplemental Rent paid under the Lease in respect of the APU at
                the date such work starts less the aggregate amount previously
                paid in respect of the APU by Lessor under this sub-clause;
                provided, however, that Lessee shall receive a credit at the end
                of the Term for APU Supplemental Rent accrued from the first day
                of the month in which maintenance work commences to the date of
                commencement of such maintenance work and which has been paid by
                Lessee in accordance with the terms of this Agreement but which
                has not been credited by Lessor to the cost of such maintenance
                work; and

          (v)  Landing Gear: With respect to the Landing Gear, the performance
               in accordance with Section 8.10, of all work on the landing gear
               in the nature of overhaul and requiring removal and disassembly,
               the lesser of (x) the amount of that invoice and (y) an amount
               equal to the aggregate amount of the Landing Gear Supplemental
               Rent paid under the Lease at the date such work starts less the
               aggregate amount previously paid by Lessor under this sub-clause.

     PROVIDED THAT Lessor will not pay any such contribution:

          (a)  in respect of paragraphs (i)-(v) above, for repairs arising as a
               result of accidents or incidents (whether or not eligible for
               recovery under Lessee's insurance), operational or maintenance
               mishandling or airworthiness directive work (except as otherwise
               agreed by Lessor); nor

          (b)  in respect of paragraphs (ii) and (iii) above, for repairs
               arising as a result of foreign object damage, the removal,
               installation, maintenance and repair of QEC (Quick Engine Change
               Kits) and/or, unless approved by Lessor, any elective parts
               replacement.

8.   LESSEE'S COVENANTS

8.1  Duration

     (b)  provide Lessor with the Financial Information;

     (c)  notify Lessor, promptly, of any Event of Loss or of any event which is

          or insurance brokers relating to such claim;

     (d)  promptly notify Lessor after Lessee knows or has reason to know of the
          occurrence of a Default;

     (e)  provide Lessor, upon request, with evidence that all Taxes and charges
          incurred by Lessee in connection with the Aircraft, its location and
          its operations, including those invoiced by airports and air traffic
          control authorities, have been paid in full;

     (f)  provide Lessor with such other information concerning the location,
          condition, use and operation of the Aircraft, as Lessor may from time
          to time reasonably request;

     (g)  give Lessor prior written notice as to the time and location of the
          next Major Check (such notice to be given prior to the induction of
          the Aircraft into such Major Check); provided that, the failure to do
          so will not constitute a Default or an Event of Default; and

     (h)  notify Lessor of the imminent removal of any Engine for the purpose of
          Engine Refurbishment; provided that, the failure to do so will not
          constitute a Default or an Event of Default.

8.3  Lawful and Safe Operation

     Lessee will operate the Aircraft  for commercial purposes from the Delivery
     Date until the Return Occasion from a base within the State of Registry or
     from such other base outside the State of Registry pursuant to a sub-lease
     or a wet-lease complying with Section 8.4(a), provided, always that Lessee
     must not use or operate Aircraft or suffer or permit the Aircraft to be
     used or operated:

     (a)  in violation of any applicable Regulations, unless and solely to the
          extent the validity of such Regulations are being contested in good
          faith by appropriate proceedings so long as neither such proceedings
          nor such violation involves any material risk of the sale, forfeiture
          or loss (including loss of use) of the Aircraft, any risk of criminal

                                      22

     (e)  for purposes of training, qualifying or re-confirming the status of
          cockpit personnel except for the benefit of Lessee's cockpit
          personnel, and then only if the use of the Aircraft for such purpose
          is not disproportionate to the use for such purpose of other aircraft
          of the same type operated by Lessee.

8.4  Subleasing

     (a)  AT NO TIME PRIOR TO THE RETURN OCCASION WILL LESSEE SUB-LEASE, WET-

          OF, ANY PERSON EXCEPT:

          (i)    when the prior written consent of Lessor has been obtained; or

                 permitted under the Lease; or

          (iii)  to a Certificated Air Carrier listed on Schedule 13 or to
                 another sub-lessee to which Lessor consents in writing (in
                 either case a "Permitted Sub-Lessee") pursuant to a sub-lease
                 (a "Permitted Sub-Lease") which complies with the conditions
                 set out in Section 8.4(b) and provided that no Significant
                 Default shall have occurred and be continuing;

               under the Permitted Sub-Lease and the habitual base of the
               Permitted Sub-Lessee;

         (ii)  Term:  the term of the Permitted Sub-Lease shall not be capable
               of extending beyond two (2) months before the Scheduled Expiry
               Date;

         (iii) Form:  a Permitted Sub-Lease shall:

               (aa)   not contain provisions inconsistent with the provisions of
                      the Lease (but may impose additional or more stringent
                      obligations on any Permitted Sub-Lessee than are imposed
                      on Lessee under the Lease);

               (bb)   provide that no further subleases of the Aircraft by such
                      Permitted Sub-Lessee are permitted; and

               (cc)   include provisions substantially identical to or having
                      substantially the same effect as Sections 2.1, 5.6, 5.7,
                      5.10, 5.12, 5.16, 5.17, 8, 9, 10, 11, 13 (only those
                      provisions providing for Lessor's rights of repossession,
                      termination and general damages), 15.1, 15.8 and 16 and
                      Schedules 2 (Section 1.1), and 9 of the Lease (but the
                      Permitted Sub-Lease may impose additional or more
                      stringent obligations on any Permitted Sub-Lessee than are
                      imposed on Lessee under the Lease);

          (iv) Subordination and Assignment:  the Permitted Sub-Lease shall
               provide that (aa) the Permitted Sub-Lease is subject and
               subordinate to the Lease in all respects and the rights of the
               Permitted Sub-Lessee under the Permitted Sub-Lease are subject
               and subordinate in all respects to the rights of Lessor under the
               Lease; and (bb) prior to delivery of the Aircraft to the
               Permitted Sub-Lessee (as a condition precedent thereof), the
               Permitted Sub-Lessee shall provide an acknowledgement to Lessor
               in a form reasonably satisfactory to Lessor, confirming its
               agreement to this provision and confirming that its rights to
               possession of the Aircraft under the Permitted Sub-Lease will
               terminate immediately upon the termination of the Lease, and that
               it will redeliver the Aircraft to Lessor, upon notification from
               Lessor that an Event of Default has occurred and that it has, as
               a result thereof, terminated Lessee's right to possession of the
               Aircraft under the Lease (the "Subordination Acknowledgement")
               and (cc) Lessee may terminate such Permitted Sub-Lease following
               the occurrence of an Event of Default under the Lease where
               Lessor has terminated the leasing of the Aircraft under the Lease
               as a result thereof. The Permitted Sub-Lease shall be assigned to
               Lessor pursuant to an agreement reasonably acceptable to Lessor
               (the "Sub-Lease Assignment");

                                      24
<PAGE>

          (v)    Quiet Enjoyment: the Permitted Sub-Lease shall provide that the
                 Permitted Sub-Lessee shall have the right to quiet enjoyment of
                 the Aircraft for so long as no Event of Default has occurred
                 under the Lease and/or no event of default or termination event
                 (howsoever described) has occurred under the Permitted Sub-
                 Lease;

          (vi)   Obligations of Lessee: Lessee shall remain primarily liable
                 under the Lease for the performance and observance of all its
                 obligations to the same extent as if no Permitted Sub-Lease had
                 been entered into. To the extent that the Permitted Sub-Lessee
                 properly performs an obligation under the Permitted Sub-Lease,
                 Lessor agrees that such performance shall also be regarded as
                 discharging (to such extent) Lessee's corresponding obligation;

          (vii)  Insurances: all insurance requirements herein shall be complied
                 with either by Lessee or by the Permitted Sub-Lessee as if
                 references in the insurance provisions of the Lease to "Lessee"
                 were references to "the Permitted Sub-Lessee", and Lessee shall
                 cause the Permitted Sub-Lessee to provide the insurance
                 certificate and brokers' letter of undertaking referred to in
                 Section 9.3(c)(iii) at least five (5) Business Days prior to
                 the commencement of the Permitted Sub-Lease;

          (viii) Registration: there shall be no change in the registration of
                 the Aircraft from its State of Registry;

          (ix)   Repossession Insurance: if reasonably required by Lessor,
                 repossession insurance shall be obtained by Lessor at Lessee's
                 cost, provided that repossession insurance will not be required
                 if the Permitted Sub-Lessee meets the requirements of Sections
                 8.7(a)(iv). If repossession insurance is required, the
                 Permitted Sub-Lease must provide that, if any such repossession
                 insurance cannot be obtained or renewed, a termination event
                 will occur upon notice by Lessor to Lessee or the Permitted
                 Sub-Lessee of an inability to procure repossession insurance;

          (x)    Legal Opinions: as a condition precedent to the effectiveness
                 of the Permitted Sub-Lease, Lessee shall provide to Lessor the
                 following legal opinions (at Lessee's or Permitted Sub-Lessee's
                 expense) addressed to Lessor from counsel acceptable to Lessor;

                    (aa)  a legal opinion in relation to the Permitted Sub-Lease
                          in form and substance reasonably satisfactory to, and
                          containing such other matters set out in Schedule 8
                          requested by, Lessor and confirming further that each
                          of the Subordination

                                      25

                          Acknowledgement, the Permitted Sub-Lease and the Sub-
                          Lease Assignment is valid, binding and (except as
                          limited by any equitable principles and applicable
                          bankruptcy, insolvency, reorganization, moratorium or
                          similar laws affecting creditors' or lessors' rights
                          generally) enforceable against Permitted Sub-Lessee
                          and, in the case of the Sub-Lease Assignment, properly
                          perfected as against Lessee; and

                    (bb)  one or more legal opinions in a form and from counsel
                          reasonably acceptable to Lessor in the State of
                          Registry, the State of Incorporation for each of
                          Lessee and the Permitted Sub-Lessee and, if not in the
                          United States, State of the Habitual Base to the
                          effect, inter alia, that Lessor's interests in the
                          Aircraft will be recognized under the laws of such
                          country or countries.

                          The foregoing opinion or opinions (x) shall be
                          forwarded promptly to Lessor at least five (5)
                          Business Days prior to the effective date of the
                          Permitted Sub-Lease, and (y) may, if different
                          opinions are required hereunder, be made by a single
                          counsel qualified to render opinions in each such
                          country;

          (xi)   Filings: Lessee shall co-operate with Lessor (at no cost to
                 Lessor) in connection with the execution and filing of any
                 documents reasonably required by Lessor to be executed and
                 filed from time to time with any registry or authority in the
                 Habitual Base, the State of Registry and State of Incorporation
                 (of each of Lessee and the Permitted Sub-Lessee) in order to
                 protect the interests of Lessor in and to the Aircraft, the
                 Lease or the Permitted Sub-Lease and/or to ensure the
                 validity, enforcement or priority thereof;

          (xii)  Expenses: Lessee will pay to Lessor on demand all reasonable
                 out of pocket expenses (including legal, survey and other
                 costs) and Taxes payable or incurred by Lessor in connection
                 with the review and approval of the documentation required
                 pursuant to this Section or otherwise incurred in connection
                 with any requested sub-lease or the sub-leasing of the Aircraft
                 thereunder, and will pay any Sublease Fee specified in the
                 Aircraft Lease Agreement for such Aircraft;

          (xiii) Permitted Sub-Lease: Promptly after its execution, Lessee shall
                 provide Lessor with a copy of the signed Permitted Sub-Lease;

          (xiv)  [Intentionally Deleted]; and

                                      26
<PAGE>

          (xv)   Financing Restrictions and Requirements: If Lessee requests
                 Lessor's consent to a sub-lease, it will not be unreasonable
                 for Lessor to decline its consent to such sub-lease if such
                 sub-lease would result in a breach by Lessor of the
                 restrictions contained in Lessor's financing agreements or
                 would result in a reduction in the security value(s) of
                 aircraft financed under such financing agreements or would
                 result in the Aircraft no longer being capable of being
                 financed under such financing.

     (c)  Notwithstanding Section 8.4 (a) Lessee shall be permitted to wet lease
          or charter the Aircraft provided such wet lease or charter constitutes
          an arrangement whereby Lessee agrees to furnish the Aircraft to a
          third party pursuant to which the Aircraft (i) shall be operated
          solely by regular employees of Lessee possessing all current
          certificates and licenses that are required by applicable Regulations,
          including by the State of Registry, and shall remain in the
          operational control and possession of Lessee, (ii) shall be subject to
          insurance coverage approved by Lessor, (iii) shall be used and
          operated in accordance with the Lease and shall be maintained by
          Lessee in accordance with Lessee's Maintenance Program and Lessee's
          normal maintenance practices, and (iv) shall not be subject to any
          change in its State of Registry; and provided always that such
          arrangement is expressly subordinated to the Lease and the rights of
          Lessor thereunder and to the Aircraft.

     (d)  A Permitted Sub-Lessee shall be entitled during the term of the
          Permitted Sub-lease to operate, use, locate and employ the Airframe,
          Engines and Parts in any lawful manner not in contravention with the
          Lease.

     8.5  Inspection

     (a)  Lessee will permit Lessor's representative to inspect the Aircraft at
          any time; provided that, unless (i) a Default has occurred and is
          continuing or (ii) Lessee fails to comply with Section 8.2(g) or (h),
          any such inspection shall be conducted no more than once annually.
          Lessor will give Lessee reasonable notice of inspection. Unless an
          Event of Default has occurred and is continuing, Lessor will ensure
          that such inspection will not result in a disruption to the scheduled
          operation or maintenance of the Aircraft.  Lessee shall comply with
          the reasonable requests of Lessor's representative during the course
          of an inspection but shall not be obligated to open any bays and
          panels; provided that, during an inspection conducted by Lessor
          pursuant to clause (ii) above, if such inspection occurs after the
          failure of Lessee to comply with Section 8.2(g) Lessee shall be
          obligated to open or remove all bays and panels which would have been
          opened or removed during the inspection contemplated by Section 8.2(g)
          and in the event Lessee fails to comply with Section 8.2(h), Lessee
          shall permit the

                                      27
<PAGE>

          performance of a complete video borescope inspection of the applicable
          Engine for which Lessee failed to comply with Section 8.2(h).

     (b)  The cost of conducting an inspection shall be borne by Lessor unless
          (i) at the time of  inspection an Event of Default has occurred and is
          in existence or (ii) Lessee has failed to comply with Section 8.2(g)
          or (h), in either such case the cost shall be borne by Lessee.

     (c)  No liability or obligation will be incurred by Lessor by reason of
          non-exercise by it of the inspection rights referred to in this
          Section.
8.6  Ownership; Property Interests; Related Matters

     (a)  Lessee will maintain Nameplates containing the Nameplate Inscription
     in a prominent position in the cockpit or cabin of the Aircraft and on each
     Engine; and

     (b)  Lessee will not:

          (i)    represent that it is the owner of the Aircraft or that it has
                 an economic interest (equivalent to ownership) in the Aircraft
                 for Tax treatment or other purposes;

          (ii)   take any action or fail to take any action if it could put
                 Lessor's rights or interests at risk;

          (iii)  represent to others that Lessor is associated with or
                 responsible for the business activities and/or flight
                 operations of Lessee;

          (iv)   allow the Aircraft or Lessor's interest in it or the Lease to
                 become or remain subject to any Security Interest (other than a
                 Permitted Lien); or

          (v)   allow the name of any Person to be placed on the Aircraft or any
                Engine as a designation that could reasonably be interpreted as
                a claim of ownership or as a Security Interest; provided, that
                Lessee may place thereon, or allow a Permitted Sub-Lessee to
                place thereon, its customary insignia and colors.

8.7  General

     (a)  Lessee will:

          (i)  (x) maintain its business as a commercial passenger airline, will
               preserve its corporate existence (other than as permitted in
               Section 8.7(a)(vii) below) and (y) maintain all rights,
               privileges, licenses and franchises material thereto or material
               to performing its obligations under the Lease;

<PAGE>

          (ii)   not operate the Aircraft in a manner which discriminates
                 against the Aircraft based on its leased status, when compared
                 with the manner in which Lessee operates similar aircraft,
                 engines or parts in Lessee's fleet;

          (iii)  not change the location of its chief executive office from that
                 described in the heading of the Aircraft Lease Agreement or
                 otherwise be located (as defined in Section 9-103(3)(d) of the
                 UCC) at any place in the United States other than the location
                 described the heading of the Aircraft Lease Agreement, except
                 upon thirty (30) days prior written notice thereof to Lessor;

          (iv)   remain a Certificated Air Carrier;

          (v)    [Intentionally Deleted];

          (vi)   not liquidate or dissolve (except in accordance with Section

          (vii)  not consolidate with or merge into or with any other
                 corporation or other Person, and not convey, transfer, lease or
                 otherwise dispose of all or substantially all of its property
                 and other assets to, or acquire all or any substantial part of
                 the property or other assets or capital stock of (if such
                 acquisition is analogous in either purpose or effect to a
                 consolidation or merger), any corporation or other Person,
                 unless:

                 (x)  the Person formed by or surviving such consolidation or
                      merger or the Person which acquires by conveyance,
                      transfer, lease or other disposition all or substantially
                      all of such property and other assets or stock (the
                      "Successor Entity"): (A) shall be a solvent corporation
                      organized and existing under the laws of the United States
                      or any State thereof or the District of Columbia; (B)
                      immediately after giving effect to such transaction, shall
                      have acquired or succeeded to all or substantially all of
                      the property and other assets of Lessee (if such assets
                      are being transferred) as an entirety, shall have a
                      tangible net worth (determined in accordance with GAAP) at
                      least equal to the lesser of (1) Fifty Million Dollars
                      ($50,000,000) and (2) 75% of Lessee's tangible net worth
                      (determined in accordance with GAAP) immediately prior to
                      such transaction; provided, however, Lessor shall waive
                      such requirement if, in its reasonable credit judgement,
                      the ability of the Successor Entity or Lessee, if Lessee
                      is the Successor Entity, to perform its obligations under
                      this Lease shall not be materially adversely affected by
                      such transaction; and provided, further, that in the
                      exercise of such credit judgement, Lessor shall have
                      access to full information; (C) shall be a "citizen of the
                      United States" of America as defined in Section
                      40102(a)(15)(c) of Title 49 of the U.S.C. and Certificated
                      Air Carrier; and (D) unless Lessee is

<PAGE>

                      acquiring the assets or capital stock of another Person,
                      Lessee shall execute and deliver to Lessor (X) such
                      recordations and filings with any Governmental Entity and
                      such other documents as Lessor determines shall be
                      reasonably necessary or advisable to evidence, such
                      consolidation, merger, sale, lease, transfer or other
                      disposition and (Y) an agreement, in form and substance
                      reasonably satisfactory to Lessor, which is a legal,
                      valid, binding and enforceable assumption by such
                      Successor Entity of the due and punctual performance and
                      observance of each covenant and condition of the Lease and
                      the other related documents to which Lessee is a party,
                      and shall provide an officer's certificate to such effect
                      and to the effect that the other requirements of this
                      Section have been satisfied, and a legal opinion from
                      counsel to such effect and otherwise in such reasonably
                      satisfactory to Lessor; and

               (y)    immediately prior to and after giving effect to such
                      transaction, no Event of Default or Payment Default shall
                      have occurred and be continuing.

8.8  Records

     Lessee will keep all Aircraft Documents and Records:

     (a)  in English;

     (b)  in a manner consistent with Lessee's existing record keeping
          practices; and

     (c)  so they meet the requirements of applicable Regulations (including FAR
          91.417) and Lessee's Maintenance Program.

8.9  Protection

     Lessee will:

     (a)  take all actions that are within its control to keep the Aircraft
          registered with the Air Authority in the name of Lessor; and

     (b)  upon the request of Lessor, make any and all filings required to be
          made with the Air Authority registry that are within its control and
          take all other actions within its control that are necessary or
          advisable to reflect on the Air Authority registry any change in (i)
          the ownership of the Aircraft, or (ii) in the interests of Lessor in
          the Lease or the Aircraft, or (iii) any modification to the Aircraft
          (such as the permanent replacement of any Engine in accordance with
          the Lease) or (iv) any applicable Regulation.  Lessor will bear any
          costs incurred as a consequence of a change in ownership of the
          Aircraft or in the identity of Lessor and Lessee will bear any other
          costs incurred in complying with this Section, including in connection
          with the replacement of any Engine.

                                      30

8.10 Maintenance and Repair

     Lessee will maintain, overhaul and repair the Aircraft (or arrange for the
     Aircraft to be maintained, overhauled and repaired), so that:

     (a)  the Aircraft is kept in as good operating condition and repair as the
          condition of the Aircraft as at Delivery and after giving effect to
          any post-Delivery modifications, repairs or maintenance paid for or
          otherwise provided by or on behalf of Lessor, except for ordinary wear
          and tear;

     (b)  the Lessee has a current certificate of airworthiness (issued by the
          Air Authority in the appropriate public transport category) for the
          Aircraft in good standing at all times;

     (c)  the Aircraft complies with (i) all applicable Regulations including
          the standard stipulated by FAR Part 121 Subpart L and any other rules
          and regulations of the FAA and in at least the same manner and with at
          least the same care, including maintenance scheduling, modification
          status and technical condition, as is the case with respect to similar
          aircraft owned or otherwise operated by Lessee and as if Lessee were
          to retain and continue operating the Aircraft in its fleet after the
          Expiry Date, including all maintenance to the Airframe, any Engine or
          any Part required to maintain all warranties, performance guaranties
          or service life policies in full force and effect; provided that,
          without in any way limiting Lessee's obligations under the Lease,
          nothing herein shall prevent Lessee, in determining whether to perform
          Optional Maintenance on the Airframe or any Engine, from taking into
          account that the Lessee shall be redelivering the Aircraft on the
          Scheduled Expiry Date, and Lessee may therefore elect not to perform
          such Optional Maintenance; and (ii) the requirements of all
          Airworthiness Directives and all service bulletins designated by the
          State of Design or State of Registry as "mandatory," and to be carried
          out before the Scheduled Expiry Date; and

     (d)  all maintenance is carried out according to Lessee's Maintenance
          Program in at least the same manner and with at least the same care,
          including maintenance scheduling, modification status and technical
          condition, as is the case with respect to similar aircraft owned or
          otherwise operated by Lessee; provided that, without in any way
          limiting Lessee's obligations under the Lease, nothing herein shall
          prevent Lessee, in determining whether to perform Optional Maintenance
          on the Airframe or any Engine, from taking into account that the
          Lessee shall be redelivering the Aircraft on the Scheduled Expiry
          Date, and Lessee may therefore elect not to perform such Optional
          Maintenance.

8.11 Removal of Engines and Parts

                                      31
<PAGE>

     (a)  General:  Lessee must replace, within ninety (90) days thereof (or in
          the event Lessee does not have such an engine available, such longer
          time as Lessor and Lessee acting reasonably mutually agree is
          necessary to obtain such an engine), any Engine that has suffered an
          Engine Event of Loss in accordance with Section 8.11(b).  Any Engine
          which otherwise is lost, stolen, destroyed, seized, obsolete,
          confiscated, damaged beyond repair or permanently rendered unfit for
          any reason, must be replaced in accordance with Section 8.11(b).  Any
          Engine may be installed on another aircraft Lessee owns or leases in
          accordance with Section 8.11(c).  Lessee may install an engine (other
          than an Engine) on the Aircraft in accordance with Section 8.11(d).
          For so long as a GE Entity is the owner of the Aircraft and the Other
          Aircraft (at the time of installation), Lessee may install any of the
          Other Engines on the Aircraft on a permanent basis in accordance with
          Section 8.11(b).  Lessee shall obtain from any person to whom
          permanent possession of an Engine is given (an "Engine Possession"),
          and from the lessor and/or owner of any airframe on which an Engine is
          installed and from any holder of a Security Interest in any airframe
          on which an Engine is installed, an agreement in writing (which
          agreement, in the case of a lease or Security Interest, may be
          contained in the applicable lease or security interest agreement
          covering such airframe) to Lessor, that such Person will not seek to
          acquire, claim or exercise as against Lessor any rights, title or
          interest with respect to such Engine as a result of such Engine being
          installed on such Airframe or, in the case of an Engine Possession,
          while such Person is otherwise in the permanent possession of the
          Engine.  In the event Lessee shall have received from a lessor of or
          secured party holding a Security Interest in any airframe leased to
          Lessee or owned by Lessee a written agreement pursuant to the
          foregoing sentence and the lease or Security Interest covering such
          airframe (such lease or security agreement being referred to as an
          "Aircraft Agreement") also covers an engine or engines owned by the
          lessor under such lease or subject to such Security Interest in favor
          of the secured party under such Security Interest, Lessor hereby
          agrees for the benefit of such lessor or secured party (and hereby
          agrees for the benefit of any lessor or secured party with respect to
          a spare engine not subject to an Aircraft Agreement) that Lessor will
          not seek to acquire, claim or exercise as against such lessor or
          secured party, any right, title or interest in relation to any such
          engine as the result of such engine being installed on the Airframe at
          any time while such engine is subject to such lease or Security
          Interest and owned by such lessor or subject to a Security Interest in
          favor of such secured party.

     (b)  Permanent Replacement of Engines:  If Lessee permanently replaces an
          Engine:

          (i)    the replacement engine (except if such replacement is one of
                 the Other Engines) must be of the same manufacturer and model,
                 or at Lessee's option an engine of an improved model, and have
                 equivalent or better remaining useful life, modification
                 status, time elapsed since hot section refurbishment, cold
                 section refurbishment, reduction gear overhaul, life limited
                 part utility,

                                      32
<PAGE>

                 serviceability and equivalent remaining warranty status as the
                 Engine it replaces, and is otherwise of an equivalent or better
                 value and utility and suitable for installation and use on the
                 Airframe without impairing the value or utility of the Airframe
                 and compatible with the remaining installed Engine(s); provided
                 that, if Lessee is unable to obtain a replacement engine which
                 meets the above requirements, Lessor agrees to discuss in good
                 faith with Lessee alternative requirements for a replacement
                 engine;

          (ii)   [Intentionally Deleted];

          (iii)  the replacement engine must have become and remain, until
                 replaced in accordance with this Section, the property of
                 Lessor free from Security Interests (other than Permitted
                 Liens); and

          (iv)   Lessee must have history and maintenance records of the
                 replacement engine.

     (c)  Other Aircraft:  An Engine may be installed on an aircraft which
          Lessee owns or leases if:

          (i)    no Significant Default has occurred and is continuing;

          (ii)   Lessee has operational control over the aircraft;

          (iii)  Lessor keeps the ownership of the Engine concerned until
                 replaced in accordance with this Section;

          (iv)   the Engine does not become subject to a Security Interest and
                 the applicable airframe is not subject to any Security Interest
                 except a Permitted Lien or a lease or Security Interest
                 described in Section 8.11(a) above; and

          (v)    unless replaced pursuant to Section 8.11(b), the Engine is
                 removed from the aircraft as soon as practicable but not later
                 than the Expiry Date.

     (d)  Temporary Replacement:  Lessee may install any engine or part on the
          Aircraft as a temporary replacement if:

          (i)    only with respect to the installation of any such engine, no
                 Significant Default has occurred and is continuing;

          (ii)   there is not then available on terms reasonably acceptable to
                 Lessee an engine or part complying with the requirements of the
                 Lease for a replacement Engine or Part;

                                      33
<PAGE>

          (iii)  it would result in an unreasonable disruption of the operation
                 of the Aircraft or the business of Lessee to have the Aircraft
                 grounded until such time as an engine or part complying with
                 the requirements of the Lease for a replacement Engine or Part
                 becomes available for installation;

          (iv)   as soon as practicable after an engine or part is installed on
                 the Aircraft, but before the earlier of ninety (90) days after
                 such temporary replacement (unless such temporary replacement
                 engine is one of the Other Engines) and in all cases (including
                 if the engine is one of the Other Engines) the Expiry Date,
                 Lessee removes that engine or part and replaces it with the
                 original Engine or Part (or, in the case of a Part, by a part
                 which is allowed by Section 8.11(e)); and

          (v)    the Insurances for the Aircraft are not affected.

     (e)  Permanent Replacement of Parts: Except if the Airframe or an Engine to
          which a Part relates has suffered an Event of Loss, the Lessee, at its
          sole cost and expense, will promptly replace all Parts that may from
          time to time become worn out, lost, stolen, destroyed, seized,
          obsolete, confiscated, damaged beyond repair or permanently rendered
          unfit for any reason whatsoever. In addition, in the ordinary course
          of maintenance, service, repair, overhaul or testing, the Lessee, at
          its sole cost and expense, may remove any Parts provided, that the
          Lessee, at its sole cost and expense, replace such Parts promptly with
          replacement parts or temporary replacement parts in accordance with
          Section 8.11(d). All replacement parts must be free from Security
          Interests (other than Permitted Liens), in good operating condition,
          have a value and utility the same or better than the Part it is
          replacing, have as much useful life available until the next scheduled
          maintenance procedure (if applicable), be of the same or more advanced
          make or model and of the same interchangeable modification status as
          the Part it is replacing. Lessee must have full details of the source
          and maintenance records of the replacement part and in the case of
          serialized rotable parts, also have a complete history. All Parts at
          any time removed from the Airframe or Engine shall remain the property
          of the Lessor and subject to this Lease, no matter where located,
          until such time as such Parts shall be replaced by replacement parts
          that have been incorporated or installed in or attached to such
          Airframe or Engine and that meet the requirements for replacement
          parts set forth in this Section 8.11(e). Immediately upon any
          replacement part (other than temporary replacement parts) meeting the
          requirements of this Section 8.11(e) becomes incorporated or installed
          in or attached to an Airframe or Engine, without further act, (i)
          title to the replaced part shall thereupon vest in the Lessee in AS-IS
          WHERE-IS condition, free from Security Interests of the Lessor and
          shall no longer be considered a Part hereunder; (ii) title to such
          replacement part shall thereupon vest in the Lessor; and (iii) such
          replacement part shall become subject to the Lease and be deemed part
          of such Airframe or Engine, as the case may be, for all purposes
          hereof to

                                      34
<PAGE>

          the same extent as the Parts originally incorporated or installed in
          or attached to such Airframe or Engine

     (f)  Pooling/Interchange:  Lessee shall not subject any Engine or Part to
          any pooling, interchange, lease or similar arrangement unless (i)
          Lessee obtains Lessor's prior written consent thereto or (ii) such
          pooling arrangement provides that title to a replacement part
          incorporated or installed in or attached to an Airframe or Engine
          pursuant to Section 8.11(e) shall vest in Lessor as provided in
          Section 8.11(e)(ii) and (iii).

8.12 Equipment Changes

     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 or required by the Lease; or

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

          (iii)  is required to be made by any applicable Law; or

          (iv)   is required to be made in order to maintain the Insurances.

  So long as no Event of Default has occurred and is continuing, Lessee may
  remove any Equipment Change provided that (x) the Equipment Change is not
  required pursuant to the terms of the Lease or to maintain the Insurances and
  (y) such removal will not diminish the value, utility, airworthiness or
  condition of the Aircraft below that which would have been otherwise required
  under the Lease had such Equipment Change not been made.  Furthermore, Lessor
  may require Lessee to remove any Equipment Change made pursuant to clause
  8.12(ii) above on the Expiry Date and to restore the Aircraft to its condition
  prior to that Equipment Change; provided, however, that Lessor shall advise
  Lessee of its request to remove any Equipment Change no later than sixty (60)
  days prior to the commencement of the applicable re-delivery C-check.  Any
  Equipment Change not so removed becomes the property of Lessor.

8.13 Title on an Equipment Change

     Title to any equipment that becomes a Part or an Engine after the Delivery
     Date shall vest in Lessor solely by virtue of its attachment to the
     Airframe or an Engine and it shall then be subject to the Lease as if it
     were attached to the Aircraft at Delivery.  If so requested by Lessor, with
     respect to an Engine, Lessee will provide a properly executed bill of sale
     or similar instrument to evidence the vesting of title to any such
     equipment in Lessor.  After Lessor has determined that Lessee has
     permanently replaced an Engine in accordance with

                                      35
<PAGE>

     Section 8.11(b) and this Section 8.13, Lessor will without recourse or
     warranty (except as to the absence of Lessor's Liens), transfer to Lessee
     all of Lessor's rights to the engine that has been replaced, on an AS-IS,
     WHERE-IS basis, and will at Lessee's expense provide a bill of sale or
     similar instrument as Lessee may reasonably request to evidence such
     transfer. Lessee shall indemnify, on an After-Tax Basis, Lessor and each
     other Tax Indemnitee for all fees, expenses and Taxes incurred by Lessor or
     any other Tax Indemnitee in connection with any such transfer.

9.   INSURANCE

     (a)  Public Liability and Property Damage Insurance.

          (i)    Subject to the rights of the Lessee under Section 9(d), the
          Lessee shall, without expense to the Lessor maintain or cause to be
          maintained in effect at all times during the Term, with insurers of
          nationally or internationally recognized reputation and responsibility
          which normally participate in airline insurance programs,
          comprehensive airline public liability insurance (including, without
          limitation, aircraft third party liability, baggage and mail and
          aviation general third party liability, contractual liability,
          passenger legal liability, cargo liability, property damage liability,
          general third party legal liability and product liability coverage but
          excluding manufacturer's product liability coverage) with respect to
          the Aircraft in an amount not less than the greater of (x) the amount
          which Lessee may carry from time to time on other similar aircraft in
          its fleet (whether owned or leased) and (y) the Minimum Liability
          Amount; provided that an agreement of the Government for the benefit
                  --------
          of the Additional Insureds to insure against or indemnify for
          substantially the same risks to at least the same amount shall satisfy
          the requirements of this Section 9(a), provided that on or prior to
                                                 --------
          the date of such agreement, the Lessee shall provide an Officer's
          Certificate of the Lessee certifying that any such insurance or
          indemnity provides protection no less favorable than insurance
          coverage that would comply with this Section 9.  Such insurance shall
          be of the same type and covering the same risks usually carried by the
          Lessee with respect to similar aircraft and engines and shall provide
          coverage that is in substantially similar form, of such types and
          having limits within the range of limits (but no less than the Minimum
          Liability Coverage) as are customarily obtained by similarly situated
          United States carriers operating similar aircraft on similar routes.

          (ii)   During any period that the Aircraft is grounded and not in
          operation for any reason, the Lessee may modify the insurance required
          by this Section 9(a) to modify the amounts of public liability and
          property damage insurance, the scope of the risks covered and the type
          of insurance, in all circumstances to conform to such insurance
          customary in the United States airlines industry for regional air
          carriers similarly situated with the Lessee in respect of similar
          aircraft which are grounded, not in

                                      36
<PAGE>

          operation, and stored or hangared, except that in all instances, the
          amounts of coverage and scope of risk covered and the type of
          insurance shall be at a minimum no less favorable than the insurance
          as from time to time applicable to aircraft owned or leased by Lessee
          on the ground, not in operation, and stored or hangared.

     (b)  Insurance Against Loss or Damage to the Aircraft and Engines.

          (i)    Subject to the rights of the Lessee under Section 9(d), the
          Lessee shall, without expense to the Lessor, maintain or cause to be
          maintained in effect at all times during the Term with insurers of
          nationally recognized responsibility which normally participate in
          airline insurance programs (i) all risk (including U.S. limited form
          of war risk insurance covering (but not limited to) hijacking,
          strikes, civil commotion, terrorist acts and acts of sabotage while
          the Aircraft is operated in the U.S. and Canada), agreed value,
          ground, taxiing and flight hull insurance, which may, except as
          expressly provided in this Section 9(b), exclude war risks and allied
          perils, covering the Aircraft for an amount at all times (even when
          the Aircraft is grounded or in storage) not less than the Agreed Value
          from time to time; provided that, neither the Lessee nor any Permitted
                             -------- ----
          Sub-Lessee shall be required to maintain all-risk flight aircraft hull
          insurance with respect to any period in which the Aircraft is grounded
          and properly stored or hangared.  Such insurance shall not provide
          insurers with a right to replace the Airframe or any Engine with
          another airframe or engine.  Such hull insurance or other personal
          property insurance of the Lessee (or a Permitted Sub-Lessee) shall
          cover Engines or engines and Parts temporarily removed from the
          Airframe, pending replacement by installation of the same or similar
          Engines, engines or Parts on the Airframe.  Such insurance shall be on
          a replacement cost basis in respect of damage not constituting an
          Event of Loss and on an agreed value basis in respect of an Event of
          Loss and shall be of the same type and covering the same risks usually
          carried by the Lessee with respect to similar aircraft and engines and
          shall provide coverage that is in substantially similar form, of such
          types and having limits within the range of limits (but no less than
          Agreed Value from time to time) as are customarily obtained by
          similarly situated United States carriers operating similar aircraft
          on similar routes. If and to the extent that the Lessee or a Permitted
          Sub-Lessee operates the Aircraft (A) on routes where it maintains war
          risk, hijacking or allied perils insurance in effect with respect to
          other similar owned or leased aircraft in its fleet, (B) on routes
          where the custom in the industry is to carry war risk, hijacking or
          allied perils insurance or (C) in any area of recognized hostilities,
          the Lessee or such Permitted Sub-Lessee shall maintain or cause to be
          maintained such insurance in effect with respect to the Aircraft in
          the amount at least equal to the Agreed Value from time to time.  An
          agreement by the Government to insure against or indemnify for
          substantially the same risks to at least the same amount will satisfy
          any of the

                                      37
<PAGE>

          requirements of this Section 9(b).  Notwithstanding the
          foregoing, the Lessee shall not be required to maintain war risk
          insurance (except the U.S. limited form of war risk insurance noted
          above) so long as the Aircraft is operated only within the United
          States and Canada.

          (ii)   During any period that the Aircraft is on the ground and not in
                 operation, the Lessee may carry or cause to be carried, in lieu
                 of the insurance required by this Section 9(b), insurance
                 otherwise conforming with the provisions of this Section 9(b)
                 except that the scope of the risks and the type of insurance
                 shall be in substantially similar form, of such types and
                 having limits within the range of limits (but no less than
                 Agreed Value from time to time) as are customarily obtained by
                 similarly situated United States carriers in respect of similar
                 aircraft which are grounded, not in operation, and stored or
                 hangared, provided that the scope of the risks and the type of
                           --------
                 insurance shall be the same as from time to time applicable to
                 aircraft owned by the Lessee of the same type similarly on the
                 ground and not in operation, provided further that the Lessee
                                              -------- -------
                 shall maintain Insurance against risk of loss or damage to the
                 Aircraft in an amount equal to the Agreed Value from time to
                 time during such period that the Aircraft is on the ground and
                 not in operation.

     (c) Additional Insureds; Loss Payment. The Lessee shall cause all policies
     of insurance carried in accordance with this Section 9 to name the
     Indemnitees as additional insureds as their respective interests may appear
     as additional insureds. Such policies shall provide with respect to such
     Indemnitees that (i) none of their respective interests in such policies
     shall be invalidated by any act or omission or breach of warranty or
     condition contained in such policies by the Lessee or any other Person
     (other than such Additional Insured) or, in the case of any particular
     Indemnitee, any other Indemnitee and shall insure the respective interests
     of the Indemnitees regardless of any breach or violation of any warranty,
     declaration or condition contained in such policies by the Lessee or any
     Permitted Sub-Lessee; (ii) in the case of any particular Indemnitee, no
     cancellation or lapse of coverage for nonpayment of premium or otherwise,
     and no substantial change of coverage which adversely affects the interests
     of any such Indemnitee, shall be effective as to such Indemnitee until
     thirty (30) days (or such lesser period as may be applicable in the case of
     any war risk coverage) after receipt by such Indemnitee of written notice
     from the insurers of such cancellation, lapse or change; (iii) they shall
     have no liability for premiums, commissions, calls, assessments or advances
     with respect to such policies; (iv) such policies will be primary without
     any right of contribution from any other insurance carried by such
     Indemnitees; (v) the insurers waive any rights of set-off (including for
     unpaid premiums), counterclaim, deduction or subrogation whether by
     attachment or otherwise, against such Indemnitees; (vi) such policies shall
     apply worldwide and have no territorial restrictions or limitations
     (except, in the case of war, hijacking or

                                      38
<PAGE>

     related perils insurance, as otherwise permitted hereunder); (vii) shall
     contain a 50/50% Clause per Lloyd's Aviation Underwriter's Association
     Standard Policy Form AVS 103; and (viii) losses shall be adjusted with the
     Lessee (or, if an Event of Default shall have occurred and be continuing,
     with the loss payee referred to in the last sentence of this Section 9(c));
     provided, that, in the case of an Event of Loss, no adjustment (other than
     --------
     hull deductibles) shall reduce the amount payable under such policy to less
     than the agreed value required by Section 9(b). Each liability policy shall
     provide that all the provisions thereof, except the limits of liability,
     shall operate in the same manner as if there were a separate policy
     covering each insured and each hull policy shall provide that the exercise
     by the insurer of rights of subrogation derived from rights retained by the
     Lessee will not delay payment of any claim that would otherwise be payable
     but for such rights of subrogation. Each hull policy shall name the Lessor
     as loss payee; provided that, so long as the insurers shall not have
                    -------- ----
     received written notice that an Event of Default has occurred and is
     continuing, if insurance proceeds under a hull policy in the aggregate
     equal $1,000,000 or less, then such proceeds shall be payable to the Lessee
     and, notwithstanding the foregoing, any amounts (i) of any proceeds which
     in the aggregate exceed $1,000,000, (ii) of any proceeds in respect of a
     total loss or an Event of Loss or (iii) if the insurers shall have received
     written notice that an Event of Default has occurred and is continuing, any
     proceeds with respect to any single loss, shall be payable to such loss
     payee.

     (d)  Deductibles and Self-Insurance.  The Lessee may from time to time
     self-insure, by way of deductible or premium adjustment provisions in
     insurance policies or otherwise, the risks required to be insured against
     pursuant to this Section 9 under a program applicable to all aircraft in
     the Lessee's fleet in such amounts as are then self-insured with respect to
     similar owned or leased aircraft in the Lessee's fleet but in no case shall
     such self-insurance in the aggregate exceed, in addition to the Lessee's
     normal deductible per occurrence relating to damage (but not total loss) to
     aircraft for each aircraft in the Lessee's fleet (which normal deductible
     amount shall not to exceed the Deductible Amount in respect of the
     Aircraft), an amount equal to 3% of the Lessee's tangible net worth (but in
     no event exceed $15,000,000 (including, for purposes of calculating the
     amount of $15,000,000, the amount of such normal deductible applicable to
     the Aircraft (but not any other aircraft in the Lessee's fleet))),
     calculated as at the end of the Lessee's immediately preceding fiscal year.

     (e)  Application of Hull Insurance Proceeds. As between the Lessor and the
     Lessee, any payments received under policies of hull or other property
     insurance required to be maintained by the Lessee pursuant to Section 9(b),
     shall be applied as follows:

               (i)   if such payments are received with respect to loss or
               damage (including an Event of Loss with respect to an Engine) not
               constituting an

                                      39
<PAGE>

               Event of Loss with respect to the Airframe, payments in the
               aggregate of $1,000,000 or less shall be paid over to or retained
               by the Lessee and any payments which in the aggregate are greater
               than $1,000,000 shall be paid over to or retained by the Lessor
               for payment to the Lessee only upon performance of its repair or
               replacement obligation; and

               (ii)  if such payments are received with respect to an Event of
               Loss with respect to the Airframe so much of such payments as
               shall not exceed the Agreed Value and other amounts required to
               be paid by the Lessee shall be applied in reduction of the
               Lessee's obligation to pay such amounts if not already paid by
               the Lessee, and to reimburse the Lessee if such amounts shall
               have been paid, and the balance, if any, of such payments shall
               be promptly paid over to or retained by the Lessee.


     (f)  Insurance for Own Account. Nothing in this Section 9 shall prohibit
     the Lessor, the Lessee or any Indemnitee from obtaining insurance with
     respect to the Aircraft for its own account (including, without limitation,
     in the case of the Lessee, hull insurance under the same policies
     maintained pursuant to this Section 9 in amounts in excess of those
     required to be maintained pursuant to this Section 9) and any proceeds
     payable thereunder shall be payable as provided in the insurance policy
     relating thereto, provided that no such insurance may be obtained which
                       --------
     would limit or otherwise adversely affect the availability of coverage or
     payment of any insurance required to be obtained or maintained pursuant to
     this Section 9, it being understood that all salvage rights to the Airframe
     or the Engines shall remain with the Lessee's insurers at all times.

     (g)  Reports, etc.  Lessee will furnish, or cause to be furnished,
     to the Lessor (A) on or prior to the Delivery Date, insurance certificates
     describing in reasonable detail the insurance maintained by Lessee as
     required pursuant to this Section 9, (B) prior to the cancellation, lapse
     or expiration of the insurance policies required pursuant to this Section
     9, evidence of renewal of such insurance policies, and (C) on or prior to
     the Delivery Date and on or before the renewal dates of the insurance
     policies carried by the Lessee pursuant to this Section 9, a report signed
     by a firm of recognized aircraft insurance brokers of good reputation, not
     affiliated with the Lessee, which brokers may be regularly retained by the
     Lessee and reasonably satisfactory to the Lessor, stating the opinion of
     such firm that (i) all premiums in connection with the insurance then due
     have been paid, (ii)  the insurance then carried and maintained on the
     Aircraft complies with the terms hereof and, in the case of renewal
     insurance, that such renewal insurance will on and after the effective date
     thereof so comply with the terms hereof and (iii) to the best of such
     firm's knowledge, such insurance provides coverage that is in substantially
     similar form, of such types and having limits within the range of limits as
     are customarily obtained by similarly situated United States carriers
     operating similar aircraft on similar routes, provided that all information
                                                   --------
     contained in such

                                      40
<PAGE>

     report shall be held confidential by the Lessor and shall not be furnished
     or disclosed by it to any Person except (A) its legal counsel, independent
     certified public accountants, insurance brokers or advisors or other agents
     who agree to hold such information confidential, (B) to any bona fide
     prospective and permitted transferees of Lessor and their respective agents
     (provided that each such transferee shall agree for the benefit of the
      --------
     Lessee to hold all such information similarly confidential), (C) as may be
     required by applicable Law or by any court or administrative order or
     decree or governmental ruling or (D) as may be necessary for purposes of
     enforcement of Lease or (E) to rating agencies. The Lessee will instruct
     such firm to give prompt written advice to the Lessor of any default in the
     payment of any premium and of any other act or omission on the part of the
     Lessee (or any Permitted Sub-Lessee) of which it has knowledge and which
     would in such firm's opinion invalidate or render unenforceable, in whole
     or in any material part, any insurance on the Aircraft. The Lessee will
     also instruct such firm to advise the Lessor in writing at least thirty
     (30) days prior to the termination or cancellation of, or material adverse
     change in, such insurance carried and maintained on the Aircraft pursuant
     to this Section 9 (or such lesser period as may be applicable in the case
     of war risk coverage), provided, that in respect of war risk or allied
                            --------
     perils coverage, if the notice period specified above is not obtainable,
     the insurance broker shall provide for as long a period of prior notice as
     shall then be obtainable.

     (h)  Right to Pay Premiums. The Indemnitees shall have the rights but not
     the obligations of an additional named insured. None of Lessor and the
     other Indemnitees shall have any obligation to pay any premium, commission,
     assessment or call due on any such insurance (including reinsurance).
     Notwithstanding the foregoing, in the event of cancellation of any
     insurance due to the nonpayment of premiums, each of Lessor and the other
     Indemnitees shall have the option, in its sole discretion, to pay any such
     premium in respect of the Aircraft that is due in respect of the coverage
     pursuant to this Lease and to maintain such coverage, as Lessor or the
     other Indemnitees may require, until the scheduled expiry date of such
     insurance and, in such event, Lessee shall, upon demand, reimburse Lessor
     and the other Indemnitees for amounts so paid by them.

     (i)  Spares Physical Damage Insurance. During any period that an Engine is
     not attached to the Airframe or any other airframe and not otherwise
     subject to coverage by a hull policy maintained by the Lessee (or a
     Permitted Sub-Lessee), the Lessee shall maintain or cause to be maintained
     spares physical damage insurance covering such Engine in an aggregate
     amount not less than the amount commercially available in aviation
     insurance markets except that the scope of the risks and the type of
     insurance shall be in substantially similar form, of such types and having
     limits within the range of limits as are customarily obtained by similarly
     situated United States carriers operating similar engines not attached to
     any airframe, provided that the scope of the risks and the type of
                   --------
     insurance shall be the same as from time to time

                                      41
<PAGE>

     applicable to engines owned or leased by the Lessee of the same type and
     similarly not attached to any airframe.

10.  INDEMNITY

     (a)  Except as provided in Section 10(b) below, Lessee agrees to assume
          liability for and to indemnify each of the Indemnitees against and
          agrees to pay on demand any and all Losses which an Indemnitee may at
          any time suffer or incur at any time, whether directly or indirectly,
          arising out of, related to or in any way connected with:

          (i)    the ownership, maintenance, overhaul, service, repair,
                 delivery, possession, transfer of possession, registration,
                 control, storage, modification, leasing, insurance, inspection,
                 testing, design, date processing, sub-leasing, use, condition,
                 redelivery or other matters relating to the Aircraft, any
                 Engine or any Part (regardless of whether in the air or on the
                 ground, and regardless of whether such Losses are based on
                 strict liability in tort, any act or omission, including the
                 negligence, of any Indemnitee, or otherwise); or

          (ii)   any breach by the Lessee of any of its obligations under the
                 Lease; or

          (iii)  the design, testing or use of or any article or material in,
                 the Aircraft, any Engine or any Part or its use or operation,
                 including any defect in design and regardless of whether it is
                 discoverable, and any infringement of patent, copyright,
                 trademark, design or other proprietary right claimed by any
                 Person or a breach of any obligation of confidentiality claimed
                 to be owed to any Person.

                 For the avoidance of doubt, the reference to "ownership" in
                 clause (i) shall not require Lessee to indemnify Lessor in
                 respect of (y) any defect in Lessor's title to the Aircraft or
                 (z) any decline in residual value of the Aircraft.

     (b)  Lessee is not required to indemnify any particular Indemnitee under
          this Section, to the extent a particular Loss is:

          (i)    caused by the willful misconduct of that Indemnitee or gross
                 negligence of that Indemnitee, other than gross negligence
                 imputed to that Indemnitee by reason of its interest in the
                 Aircraft or the Lease;

          (ii)   caused by Lessor's breach of the Lease which does not result
                 from a Default;

          (iii)  related to any Taxes (but without prejudice to any Indemnitee's
                 rights under any other provision of this Lease relating to
                 Taxes);

                                      42
<PAGE>

          (iv)   caused solely by an event which occurs before the commencement
                 of the Term (except where the Loss is suffered during the Term
                 as a result of a pre-Delivery defect in or otherwise arises out
                 of or relates to or is any way connected with the manufacture,
                 design, maintenance, repair, rebuilding, overhaul or
                 modification of the Aircraft);

          (v)    caused by an event which occurs after the proper redelivery of
                 the Aircraft to Lessor in compliance with the Lease and is not
                 attributable to any act, omission, event or circumstance
                 occurring prior to such redelivery;

          (vi)   caused as a result of any sale, assignment, financing,
                 securitization, transfer or other disposition (whether
                 voluntary or involuntary) by such Indemnitee of the Aircraft or
                 any interest therein or in the Lease, unless such sale,
                 transfer or other disposition has resulted from or occurred
                 following an Event of Default;

          (vii)  consists of normal administrative costs and expenses of such
                 Indemnitee (but excluding any such costs or expenses resulting
                 from the occurrence of any Event of Default); or

          (viii) consists of costs or expenses for which Lessor has expressly
                 agreed to be responsible under any other provision of the
                 Lease.

11.  EVENTS OF LOSS

11.1 Events of Loss

     (a)  If an Event of Loss occurs prior to Delivery of the Aircraft, the
          Lease will immediately terminate and except as expressly stated in the
          Lease neither party will have any further obligation except that
          Lessor will return the Deposit (if any) to Lessee and return to Lessee
          or cancel any Letter of Credit.

     (b)  If an Event of Loss occurs after Delivery, Lessee will pay or cause to
          be paid the Agreed Value to Lessor on or prior to the earlier of (i)
          ninety (90) days after the Event of Loss and (ii) the date of receipt
          of insurance proceeds in respect of that Event of Loss.

     (c)  Subject to the rights of any insurers and reinsurers or other third
          party, upon irrevocable payment in full to Lessor of the Agreed Value
          and all other amounts which may be or become payable to Lessor under
          the Lease, Lessor will without recourse or warranty (except as to  the
          absence of Lessor's Liens) transfer to Lessee all of Lessor's rights
          to the Aircraft, 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) such

                                      43
<PAGE>

          transfer, free and clear of all rights of Lessor and Lessor Liens.
          Lessee shall indemnify, on an After-Tax Basis, Lessor and each other
          Tax Indemnitee for all fees, expenses and Taxes incurred by Lessor or
          any other Tax Indemnitee in connection with any such transfer.

11.2 Requisition

During any requisition for use or hire of the Aircraft or any Engine which does
not constitute an Event of Loss:

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

     (b)  so long as no Event of Default has occurred and is continuing, Lessee
          will be entitled to any compensation paid by the requisitioning
          authority in respect of such authority's use of the Aircraft or such
          Engine during 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 the Lease.  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 promptly reimbursing Lessee for the cost of complying
          with its obligations under the Lease in respect of any such change,
          but, if any Event of Default has occurred and is continuing, Lessor
          may apply the compensation in or towards settlement of any amounts
          owing by Lessee under the Lease or the Other Agreement.

12.  RETURN OF AIRCRAFT

12.1 Return

     On the Expiry Date or redelivery of the Aircraft pursuant to Section 13.2
     or termination of the leasing of the Aircraft under the Lease, Lessee will,
     unless an Event of Loss has occurred, redeliver the Aircraft and the
     Aircraft Documents and Records at Lessee's expense to Lessor at the
     Redelivery Location, in accordance with the procedures and in compliance
     with the conditions set forth in Schedule 6, free and clear of all Security
     Interests (other than Lessor Liens) and in a condition qualifying for and
     having a valid and fully effective certification of airworthiness under FAR
     Part 121.

12.2 Non-Compliance

     If at the time of Final Inspection Lessee has not fully complied with any
     of its obligations under the Lease (including Schedule 6), or Lessee fails
     to make the Aircraft available to

                                      44
<PAGE>

     Lessor on a timely basis for inspection and redelivery pursuant to Section
     12.1 and Schedule 6 (whether such failure is due to any act or omission of
     Lessee or any other circumstance whatsoever), the Term shall be extended
     until the time when the Aircraft has been redelivered to Lessor in full
     compliance with the Lease, for the sole purpose of enabling such non-
     compliance or failure to be promptly rectified, and during such extension
     period:

     (a)  Lessee shall not use the Aircraft in flight operations except those
          related directly to the redelivery of the Aircraft to Lessor or the
          performance of Lessee's obligations in connection therewith;

     (b)  all Lessee's obligations and covenants under the Lease will remain in
          full force until Lessee so redelivers the Aircraft; and

     (c)  Lessee shall pay Rent to Lessor at a rate per month equal to the
          amount of Rent payable in respect of the last scheduled Rental Period
          plus interest at the Interest Rate (unless during such extension
          period work is being performed upon the Aircraft or an Engine to
          repair unforeseen damage or defect not capable of discovery in the
          normal course and first discovered during the performance of non-
          routine inspections or checks timely arranged as necessary to meet the
          Re-Delivery Conditions set forth in Schedule 6 herein, in which case
          such interest shall not accrue until 45 days after the scheduled re-
          delivery date of the Aircraft as set forth above), calculated on a per
          diem basis and compounded monthly.

     Any such extension shall not prejudice Lessor's right to treat such non-
     compliance or failure as an Event of Default at any time, and to enforce
     such rights and remedies as may be available to Lessor in respect thereof
     under the terms of the Lease or applicable Law.  Without limiting the
     generality of the foregoing, Lessee's Rent obligation under paragraph (c)
     above shall be without prejudice to Lessor's rights to terminate the
     letting of the Aircraft and to indemnification pursuant to Section 13.2.

     Lessor may elect (either on first tender of the Aircraft by Lessee or at
     any time during the said extension period) to accept redelivery of the
     Aircraft notwithstanding non-compliance with Section 12.1 or Schedule 6 in
     respect of the cost to Lessor of putting the Aircraft into the condition
     required by the Lease.

12.3 Redelivery

     Upon redelivery Lessee will provide to Lessor, upon reasonable advance
     notice by Lessor made prior to the Expiry Date, and at Lessor's expense,
     all documents necessary to export the Aircraft from the United States
     (including a valid and subsisting export license and export certificate of
     airworthiness for the Aircraft) or required in relation to the
     deregistration of the Aircraft with the Air Authority.

                                      45
<PAGE>

12.4 Acknowledgement

     Provided Lessee has complied with its obligations under Section 12 and
     Schedule 6 of this CTA, following redelivery of the Aircraft by Lessee to
     Lessor at the Redelivery Location, Lessor will deliver to Lessee an
     acknowledgement confirming that Lessee has redelivered the Aircraft to
     Lessor in accordance with the Lease which acknowledgement shall be, except
     as may be otherwise set forth therein, without prejudice to Lessor's
     accrued and continuing rights under the Lease or the Other Agreement.

12.5 Storage

     If Lessor so requests, upon sixty (60) days prior notice, Lessee shall
     provide up to thirty (30) days storage for the Aircraft following the last
     day of the Term at Lessor's risk and expense at a location selected by
     Lessee.  Lessor shall promptly pay to Lessee all costs of storing the
     Aircraft.

13.  DEFAULT

13.1 Events

     The occurrence of any of the Events of Default will constitute a
     repudiation (but not a termination) of the Lease by Lessee (whether the
     occurrence of any such Event of Default is voluntary or involuntary or
     occurs by operation of Law or pursuant to or in compliance with any
     judgement, decree or order of any court or any order, rule or regulation of
     any Government Entity).

13.2 Rights and Remedies

     If an Event of Default occurs, Lessor may at its option (and without
     prejudice to any of its other rights under the Lease), at any time
     thereafter and so long as the same continues (without notice to Lessee
     except as required under applicable Law):

     (a)  accept such repudiation and by notice to Lessee and with immediate
          effect cancel the leasing of the Aircraft (but without prejudice to
          the continuing obligations of Lessee under the Lease), whereupon all
          rights of Lessee under the Lease shall cease; and/or

     (b)  proceed by appropriate court action or actions to enforce performance
          of the Lease including the payment of all Rent and all other amounts
          payable to Lessor or any Indemnitee pursuant to the terms of the
          Lease; and/or

     (c)  proceed by appropriate court action or actions to recover damages for
          the breach of the Lease which shall include:

                                      46
<PAGE>

          (i)    all Rent and other amounts which are or become due and payable
                 hereunder prior to the earlier to occur of the date Lessor
                 sells or re-leases the Aircraft or receives payment of the
                 amount calculated pursuant to clause (ii) below;

          (ii)   an amount equaling the aggregate Rent for the remainder of the
                 Term (determined without reference to any right of Lessor to
                 cancel the leasing of the Aircraft, whether or not such right
                 is exercised), discounted periodically (equal to installment
                 frequency) to present worth at the Discount Rate to the date of
                 payment by Lessee to Lessor, less the amount, if any, of the
                 Mitigation Credit (calculated as provided below in Section
                 13.4);

          (iii)  all costs associated with Lessor's exercise of its remedies
                 hereunder or otherwise incurred by Lessor as a result of an
                 Event of Default, including repossession costs, legal fees,
                 Aircraft storage, maintenance and insurance costs, Aircraft re-
                 lease or sale costs (including any costs incurred to put the
                 Aircraft in the condition required by Section 12), all such
                 costs and incidental damages being referred to herein
                 collectively as "Enforcement and Remarketing Costs";

          (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, all such amounts being
                 referred to herein collectively as "Unwind Expenses";

          (v)    any loss, cost, expense or liability, or damage to Lessor's
                 residual interest in the Aircraft, sustained by Lessor due to
                 Lessee's failure to maintain the Aircraft in accordance with
                 the terms of this Agreement or Lessee's failure to redeliver
                 the Aircraft in the condition required by this Agreement,
                 including any consequential loss of revenues while the Aircraft
                 is modified to conform to the condition required by this
                 Agreement, all such amounts being referred to herein
                 collectively as "Aircraft Condition Damages"; and

          (vi)   such additional amount, if any, as may be necessary to place
                 Lessor in the same economic position, on an After-Tax Basis, as
                 Lessor would have been in if Lessee had timely performed each
                 of its obligations under this Agreement; 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

                                      47
<PAGE>

                 (and/or any engine which is not an Engine but which is
                 installed on the Airframe, subject to the rights of the lessor
                 or secured party thereof), 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, conversion
                 or otherwise, caused by such entry or taking, except damages
                 caused by gross negligence or willful misconduct; or

          (ii)   by delivering notice to Lessee, require Lessee to redeliver the
                 Aircraft to Lessor at such location as Lessor may require on
                 the Lessee's route system in the United States on the date
                 specified in such notice and in all respects in the condition
                 required by the Lease upon the Return Occasion (it being
                 understood that Lessee shall not delay any such return for the
                 purpose of placing the Aircraft in such condition, but shall
                 nevertheless be liable to Lessor for the failure of the
                 Aircraft to be in such condition); 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)  by written notice to Lessee specifying a payment date (which shall be
          a date not earlier than five (5) Business Days following the date of
          such notice), Lessor may demand that Lessee pay to Lessor, and Lessee
          shall pay to Lessor on the payment date specified in such notice (in
          lieu of the Rent due for the period commencing after the date
          specified for payment in such notice) the sum of the following
          amounts:

          (i)    all Rent and other amounts which are or are expected to become
                 due and payable hereunder prior to the payment date specified
                 by Lessor;

          (ii)   an amount equaling the aggregate Rent for the remainder of the
                 Term (determined without reference to any right of Lessor to
                 cancel the leasing of the Aircraft, whether or not such right
                 is exercised), discounted periodically (equal to installment
                 frequency) to present worth at the Discount Rate to the payment
                 date specified by Lessee to Lessor, less the amount, if any, of
                 the Mitigation Credit (calculated as provided in Section 13.4
                 below);

          (iii)  an amount equaling Lessor's Enforcement and Remarketing Costs,
                 Unwind Expenses and Aircraft Condition Damages; and

          (iv)   such additional amount, if any, as may be necessary to place
                 Lessor in the same economic position, on an After-Tax Basis, as
                 Lessor would have been in if Lessee had timely performed each
                 of its obligations under this Agreement;

                                      48
<PAGE>

          it being understood that, to the extent that any of the foregoing
          amounts represents an estimate by Lessor of losses, damages, costs or
          expenses which Lessor expects to incur, (y) Lessor shall adjust the
          amount thereof as needed to reflect the actual amount of such losses,
          damages, costs or expenses incurred by Lessor when substantially all
          of such amounts become known to Lessor, but Lessee shall nevertheless
          be obligated to pay the amount demanded by Lessor (subject to such
          subsequent adjustment), and (z) notwithstanding the amount specified
          in such demand, Lessor shall be entitled to claim such other (and
          greater) amount in any action against Lessee hereunder; and/or

     (g)  by written notice to Lessee specifying a payment date (which shall be
          a date not earlier than five (5) Business Days following the date of
          such notice), Lessor may demand that Lessee pay to Lessor, and Lessee
          shall pay to Lessor on the payment date specified in such notice (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 the Lease (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 Discount Rate, it being
          understood that upon payment of such amount, Lessee shall be deemed to
          have cured the then pending Event of Default, and in the absence of a
          further Event of Default, Lessee shall be entitled to retain
          possession of the Aircraft for the remainder of the Term; and/or;

     (h)  draw upon the Deposit or the Letter of Credit and apply such amounts
          to any amounts owing to Lessor hereunder for any or all of the
          foregoing.

     In addition to the foregoing, Lessor shall be entitled to exercise such
     other rights and remedies as may be available under applicable Law and
     Lessee shall be liable on an After-Tax Basis for, and shall pay Lessor on
     demand:  (i)  interest on all unpaid amounts at the Interest Rate, from the
     due date until the date of payment in full; (ii) 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; and (iii) all reasonable expenses, disbursements,
     costs and fees incurred in (A) repossessing, storing, preserving, shipping,
     maintaining, repairing and refurbishing the Aircraft, the Airframe, any
     Engine or Part to the condition required by Section 12 hereof and (B)
     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, but shall have no obligation,
     to make any expenditures which Lessor, in its sole discretion, considers
     advisable to repair and restore the Aircraft, the Airframe, an Engine or
     Part to the condition required by Section 12 hereof (it being understood
     that Lessee shall be liable for all such expenditures).

                                      49
<PAGE>

     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.

     Except as otherwise expressly provided herein, no remedy referred to in
     this Section 13 is intended to be exclusive, but, to the extent permissible
     under the Lease 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 Section 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 or Event of
     Default.

13.3 Power of Attorney: Lessee hereby appoints Lessor as the attorney-in-fact of
     Lessee, with full authority in the place and stead of Lessee and in the
     name of Lessee or otherwise, for the purpose of carrying out the provisions
     of the Lease and taking any action and executing any instrument that Lessor
     may deem necessary or advisable to accomplish the purposes hereof;
     provided, however, that Lessor may only take action or execute instruments
     under this Section 13 after an Event of Default has occurred and is
     continuing. Lessee hereby declares that the foregoing powers are granted
     for valuable consideration, constitute powers granted as security for the
     performance of the obligations of Lessee hereunder and are coupled with an
     interest and shall be irrevocable. Without limiting the generality of the
     foregoing or any other rights of Lessor under the Lease, upon the
     occurrence and during the continuation of an Event of Default, Lessor shall
     have the sole and exclusive right and power to (i) settle, compromise,
     compound, adjust or defend any actions, suits or proceedings relating to or
     pertaining to the Aircraft, Airframe or any Engine, or the Lease and (ii)
     make proof of loss, appear in and prosecute any action arising from any
     policy or policies of insurance maintained pursuant to the Lease, and
     settle, adjust or compromise any claims for loss, damage or destruction
     under, or take any other action in respect of, any such policy or policies.

13.4 Mitigation Credit: Lessee shall be entitled to have a Mitigation Credit
     deducted from any recovery by Lessor from Lessee of Rent for the unexpired
     portion of the Term. Such "Mitigation Credit" shall be in one of the
     following amounts, with Lessor to select the amount which in its reasonable
     judgment will place Lessor in the same economic position, on an After-Tax
     Basis, as Lessor would have been in if Lessee had timely performed each of
     its obligations under the Lease:

                                      50
<PAGE>

     (a)  in the event that Lessor has re-let the Aircraft on terms (other than
          rental payment terms) which, taken as a whole, Lessor reasonably
          regards as being substantially similar to the terms of the Lease, an
          amount equaling the aggregate basic rental payments under such
          reletting to become due for the period coinciding with the remainder
          of the Term (determined without reference to any right of Lessor to
          cancel the leasing of the Aircraft, whether or not such right is
          exercised), discounted periodically (equal to installment frequency)
          to present worth at the Discount Rate to the date of payment by
          Lessee; or

     (b)  in the event that Lessor has not re-let the Aircraft or has re-let the
          Aircraft on terms (other than rental payment terms) which, taken as a
          whole, Lessor does not reasonably regard as being substantially
          similar to the terms of the Lease, an amount equaling the fair market
          rental value (determined pursuant to the Appraisal Procedure) of the
          Aircraft for the period commencing with the date that Lessor
          reasonably anticipates that the Aircraft could be re-let at such
          rental rate and ending with the date that the Term was scheduled to
          expire (determined without reference to any right of Lessor to cancel
          the leasing of the Aircraft, whether or not such right is exercised),
          discounted periodically (equal to installment frequency) to present
          worth at the Discount Rate to the date of payment by Lessee; or

     (c)  in the event that Lessor has not recovered possession of the Aircraft,
          or Lessor has recovered possession of the Aircraft but Lessee's breach
          of the Lease has resulted in a reduction in the volume of Lessor's
          business, the amount of expense, if any, avoided by Lessor as a result
          of being relieved of its obligations to Lessee under the Lease prior
          to the date that the Term was scheduled to expire (determined without
          reference to any right of Lessor to cancel the leasing of the
          Aircraft, whether or not such right is exercised).

13.5 Sale or Re-Lease

     If an Event of Default occurs, Lessor may sell or re-lease or otherwise
     deal with the Aircraft at such time and in such manner and on such terms as
     Lessor considers appropriate in its absolute discretion, free and clear of
     any interest of Lessee, as if the Lease had never been entered into.
     Without limiting Lessee's rights under Section 13.4, Lessor shall have no
     duty or obligation to sell the Aircraft, and Lessor shall be obligated to
     attempt to re-lease the Aircraft only to the extent, if any, that it is
     required to do so under Article 2A of the UCC, and Lessee hereby disclaims
     any right to compel Lessor to sell or otherwise re-lease the Aircraft.

13.6 Removal of Lease from FAA Registry

                                      51
<PAGE>

     If an Event of Default occurs, Lessee will at the request of Lessor
     immediately take all steps necessary to enable the Aircraft to be
     redelivered to Lessor in accordance with and free and clear of the Lease
     and Lessee hereby irrevocably and by way of security for its obligations
     under the Lease appoints (which appointment is coupled with an interest)
     Lessor as its attorney-in-fact to execute and deliver any documentation and
     to do any act or thing required in connection with the foregoing.  Without
     limiting the foregoing, Lessor may file with the FAA the Lease Termination
     provided to Lessor under the Lease.

14.  TRANSFER

14.1 Lessee

     EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN SECTION 8.6(b)(iv) LESSEE WILL
     NOT ASSIGN, DELEGATE OR OTHERWISE TRANSFER (VOLUNTARILY, INVOLUNTARILY, BY
     OPERATION OF LAW OR OTHERWISE) ANY OF ITS RIGHTS OR OBLIGATIONS UNDER THE
     LEASE (INCLUDING THE AIRCRAFT LEASE AGREEMENT OR THIS CTA), OR CREATE OR
     PERMIT TO EXIST ANY SECURITY INTEREST OVER ANY OF ITS RIGHTS UNDER THE
     LEASE (INCLUDING THE AIRCRAFT LEASE AGREEMENT OR THIS CTA), AND ANY ATTEMPT
     TO DO SO SHALL BE NULL AND VOID. NOTHING IN THIS SECTION 14.1 IS INTENDED
     TO LIMIT LESSEE'S RIGHTS UNDER SECTIONS 8.4.AND 8.7(a)(vii).

14.2 Lessor

     Lessor may, without the consent of Lessee, transfer all or any of its
     rights or obligations under the Lease or all or any of its right, title or
     interest in and to the Aircraft (each a "Transfer"), including pursuant to:

     (a)  a sale and leaseback; or

     (b)  a novation or assignment of the Lease and/or a  sale of the Aircraft
          (including to a special purpose or securitization or monetization
          trust, fund, limited liability company, corporation, partnership or
          other vehicle or in connection with any other direct or indirect
          raising of capital); or

     (c)  a secured loan financing.

     Provided that:

          (i)  if at the time of any such Transfer the Lessee has any actual or
          contingent obligation to make a payment to the Lessor or the
          transferee which Lessee would not have been obliged to pay, or which
          exceeds the amount which Lessee would have been obliged to pay to
          Lessor if no such Transfer had taken place, then Lessee shall not be
          obliged to pay the amount, or such excess as the case may be (provided
          further that

                                      52
<PAGE>

          Lessee shall not be obligated under Sections 5.6 or 5.7 to pay any
          withholding tax payments under the Lease due with respect to a
          transferee that is not a United States Person (as defined in the
          Internal Revenue Code); and

          (ii)  such Transfer may be made without the prior written consent of
          the Lessee if (x) the transferee has a tangible net worth greater than
          or equal to, on the basis of its most recent audited accounts,
          twenty-five million US Dollars (US$25,000,000) or the transferee's
          obligations under the Lease are absolutely and unconditionally
          guaranteed by a Person with such a net worth or (y) the transferee has
          investment grade rated debt obligations and any obligations owed to
          Lessee under the Lease shall rank at least pari passu with such
          investment grade debt obligations.

     Lessor will promptly notify Lessee of any Transfer and Lessee agrees
     promptly to execute and deliver in connection with any Transfer such
     documents and to take such further action as Lessor may reasonably request
     to establish or protect the rights and remedies created or intended to be
     created in favor of the transferee in connection with any Transfer.  After
     any Transfer, the transferee shall be entitled to be an Indemnitee and to
     such other rights under the Lease as Lessor shall specify.  Upon an
     assignment or novation described in clause (b), Lessor shall be released
     from all obligations and liabilities under the Lease to the extent such
     obligations and liabilities are assumed by such transferee, and the Lease,
     including this CTA as in effect at that time and as incorporated in the
     Aircraft Lease Agreement, shall be deemed applicable as between Lessee and
     the transferee of the Lease and may be amended, supplemented or otherwise
     modified without the consent of the transferor (if this CTA is applicable
     to the Other Agreements not so transferred, it shall remain in full force
     and effect and may be amended, supplemented or otherwise modified without
     the consent of the transferee).  Notwithstanding any such assignment or
     novation, Lessor and each other Indemnitee shall continue to be entitled to
     indemnification under Section 10, and shall continue to be named as an
     additional insured under all Insurances referred to in Section 9 for a
     period of not less than two years after such Transfer.  The agreements,
     covenants, obligations and liabilities contained in the Lease, including
     all obligations to pay Rent and indemnify each Indemnitee, are made for the
     benefit of Lessor (and, in the case of Section 10,  each other Indemnitee)
     and its or their respective successors and assigns, notwithstanding the
     possibility that any such Person was not originally a party to the Lease or
     may, at the time such enforcement is sought, not be a party to the Lease.
     The Lessor will not Transfer its interests in the Lease or the Aircraft in
     a transaction which fails to satisfy the requirements of this Section 14.2
     and Section 14.3.

14.3 Conditions

     In connection with any such Transfer by Lessor:

     (a)  Quiet Enjoyment: as a condition precedent to such Transfer becoming
          effective, Lessor will procure that the transferee or any new owner of
          the Aircraft (except where

                                      53
<PAGE>

          such new owner is also the "Lessor" hereunder) or any new holder of a
          Security Interest in the Aircraft or any holder of an interest in the
          Aircraft or the Lease (by way of security or otherwise), as the case
          may be, shall execute and deliver to Lessee a letter of quiet
          enjoyment in respect of Lessee's use and possession of the Aircraft in
          a form substantially similar to Section 7.1 hereof and any new owner
          will acknowledge receipt of any unused Deposit and the aggregate
          amount of Supplemental Rent paid by Lessee under the Lease minus all
          amounts paid by Lessor under Section 7.2(a) of this CTA; and

     (b)  Costs: upon receipt by Lessor of a detailed invoice, Lessor shall
          reimburse to Lessee its reasonable out-of-pocket expenses (including
          reasonable legal fees and expenses) actually incurred in connection
          with co-operating with Lessor in relation to any such Transfer
          referred to in this Section 14.

15.  MISCELLANEOUS

15.1 Survival

     Lessee's obligations under Section 3 of Schedule 4, under Sections 5.6,
     5.7, 5.8, 5.10, 5.21, 9.5, 10, 12.2, 13.2 and 17.2 and under any other
     provision of the Lease providing for an obligation on the part of the
     Lessee to indemnify Lessor or any other Indemnitee shall survive the
     expiration or any termination of the Lease and continue in full force and
     effect. Lessor's obligations under 5.11, 7.2, 12.3 and 12.5 shall likewise
     survive such expiration or termination.

15.2 Waivers, Remedies Cumulative

     The rights of Lessor under the Lease may be exercised as often as
     necessary, are cumulative and not exclusive of its rights under any Law;
     and may be waived only in writing and specifically.  Delay by Lessor in
     exercising, or non-exercise of, any such right will not constitute a waiver
     of that right.

15.3 [INTENTIONALLY LEFT BLANK]

15.4 Severability

     If a provision of the Lease 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 the Lease; or

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

                                      54
<PAGE>

15.5 Remedy

     If Lessee fails to comply with any provision of the Lease, Lessor may,
     subject to Section 7.1 of this CTA, after notice to the Lessee, if
     reasonable under the circumstances and without prejudice to Lessor, without
     being in any way obliged to do so or responsible for so doing and without
     prejudice to the ability of Lessor to treat such non-compliance as a
     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 reasonable legal fees and expenses) in
     connection with the non-compliance.

15.6 Time of Essence

     The time stipulated in the Lease for all payments payable by Lessee and the
     prompt, punctual performance of Lessee's other obligations under the Lease
     are of the essence of the Lease.

15.7 Notices

     All notices under, or in connection with, the Lease will, unless otherwise
     stated, be given in writing by letter or facsimile.  Any such notice is
     deemed effectively to be given as follows:

     (i)  if by letter, on the date received; and

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

     The addresses and facsimile and telephone numbers of Lessee and Lessor are
     as set forth in the Aircraft Lease Agreement.

15.8 Governing Law; Jurisdiction; WAIVER OF JURY TRIAL

     (a)  PURSUANT TO AND IN ACCORDANCE WITH SECTION 5-1401 OF THE NEW YORK
          GENERAL OBLIGATIONS LAW, THE PARTIES HERETO AGREE THAT THE LEASE IN
          ALL RESPECTS SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
          THE LAWS OF THE STATE OF NEW YORK, UNITED STATES, AS APPLIED TO
          CONTRACTS TO BE PERFORMED WHOLLY WITHIN THE STATE OF NEW YORK
          (EXCLUSIVE OF SECTION 7-101 OF THE NEW YORK GENERAL OBLIGATIONS LAW
          WHICH IS INAPPLICABLE TO THE LEASE).  THE PARTIES AGREE THAT THE LEASE
          WAS EXECUTED AND DELIVERED IN THE STATE OF NEW YORK.

     (b)  Pursuant to and in accordance with Section 5-1402 of the New York
          General Obligations Law, Lessee and Lessor each agree that the United
          States District Court for the Southern District of New York and any
          New York state court sitting in The City of New York, New York, and
          all related appellate courts, are to have non-

                                      55
<PAGE>

          exclusive jurisdiction to settle any disputes arising out of or
          relating to the Lease and submits itself and its property to the
          non-exclusive jurisdiction of the foregoing courts with respect to
          such disputes.

     (c)  Without prejudice to any other mode of service, Lessee:

          (i)    has agreed to be served at its offices at LaGuardia Airport,
                 New York New York or any other location in New York where
                 Lessee may have an office for any proceedings before the New
                 York courts in connection with the Lease and agrees to maintain
                 the office at Laguardia Airport, New York, New York until such
                 time as Lessee notifies Lessor of the appointment of an agent
                 for service of process in New York, New York;

          (ii)   agrees that failure by such office to notify Lessee of the
                 process shall not invalidate the proceedings concerned;

          (iii)  consents to the service of process relating to any such
                 proceedings by prepaid mailing of a copy of the process to
                 Lessee's agent at the location identified in paragraph (i) or
                 by prepaid mailing by air mail, certified or registered mail of
                 a copy of the process to Lessee at the address set forth in the
                 Aircraft Lease Agreement.

     (d)  Lessee:

          (i)    waives to the fullest extent permitted by Law any objection
                 which Lessee may now or hereafter have to the courts referred
                 to in Section 15.8(b) above on grounds of inconvenient forum or
                 otherwise as regards proceedings in connection with the Lease;

          (ii)   waives to the fullest extent permitted by Law any objection
                 which Lessee may now or hereafter have to the laying of venue
                 of any suit, action or proceeding arising out of or relating to
                 the Lease brought in the courts referred to in Section 15.8(b);
                 and

          (iii)  agrees that a judgment or order of any court referred to in
                 Section 15.8(b) in connection with the Lease is conclusive and
                 binding on it and may be enforced against it in the courts of
                 any other jurisdiction.

     (e)  Nothing in this Section 15.8 limits the right of Lessor to bring
          proceedings against Lessee in connection with the Lease:

          (i)    in any other court of competent jurisdiction; or

          (ii)   concurrently in more than one jurisdiction.

                                      56
<PAGE>

     (f)  Lessee irrevocably and unconditionally:

          (i)    agrees that if Lessor brings legal proceedings against it or
                 its assets in relation to the Lease no sovereign or other
                 immunity from such legal proceedings (which will be deemed to
                 include suit, court jurisdiction, attachment prior to
                 judgement, attachment in aid of execution of a judgement, other
                 attachment, the obtaining of judgement, execution of a
                 judgement or other enforcement or legal process or remedy) will
                 be claimed by or on behalf of itself or with respect to its
                 assets;

          (ii)   waives any such right of immunity which it or its assets now
                 has or may in the future acquire and agrees that the foregoing
                 waiver shall have the fullest extent permitted under the
                 Foreign Sovereign Immunities Act of 1976 of the United States
                 and is intended to be irrevocable for the purposes of such Act;
                 and

          (iii)  consents generally in respect of any such proceedings to the
                 giving of any relief or the issue of any process in connection
                 with such proceedings including, without limitation, the
                 making, enforcement or execution against any property
                 whatsoever (irrespective of its use or intended use) of any
                 order or judgement which may be made or given in such
                 proceedings.

     (g)  TO THE EXTENT PERMITTED BY APPLICABLE LAW, EACH OF LESSEE AND LESSOR
          HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY AND ALL RIGHTS TO A
          JURY TRIAL IN RESPECT OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR
          ARISING OUT OF THE LEASE OR ANY DEALINGS BETWEEN THEM RELATING TO THE
          SUBJECT MATTER OF THE TRANSACTIONS CONTEMPLATED THEREBY OR THE
          LESSOR/LESSEE RELATIONSHIP BEING ESTABLISHED, including, without
          limitation, contract claims, tort claims, breach of duty claims and
          other common law and statutory claims.  Each of Lessor and Lessee
          represents and warrants that each has reviewed and voluntarily waives
          its jury trial rights following consultation with its legal counsel.
          TO THE EXTENT PERMITTED BY APPLICABLE LAW, THIS WAIVER IS IRREVOCABLE,
          AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS,
          SUPPLEMENTS OR MODIFICATIONS TO THE LEASE.  In the event of
          litigation, this Section may be filed as a written consent to a trial
          by the court.

15.9 Sole and Entire Agreement; True Lease; Section 1110

     (a)  Entire Agreement: The Lease is the sole and entire agreement between
          Lessor and Lessee in relation to the leasing of the Aircraft, and
          supersedes all previous

                                      57
<PAGE>

          agreements in relation to that leasing. Any amendments to the Lease
          must be made in writing and signed on behalf of Lessor and Lessee.

      (b) True Lease: The parties intend and agree that the Lease:

          (i)    constitutes a "true lease", and not a "security interest" as
                 defined in Section 1-201(37) of the UCC;

          (ii)   constitutes a "true lease" for United States Federal income tax
                 purposes; and

          (iii)  confers only a leasehold interest on Lessee in and to the
                 Aircraft on and subject to the terms of the Lease, and no
                 ownership or other interest with respect to the Aircraft is
                 provided to Lessee under the Lease.

          Lessee shall not file a tax return that is inconsistent with the
          provisions of this Section 15.9(b).

      (c) Section 1110: Lessee acknowledges that Lessor would not have entered
          into the Lease unless it had available to it the benefits of a lessor
          under Section 1110 of Title 11 of the U.S.C.  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, such event shall not be the sole basis for a
          Default or an Event of Default; provided, however, that Lessor and
          Lessee agree to amend the Lease and take such other action not
          inconsistent with the Lease 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.

15.10 Indemnitees

      All rights expressed to be granted to each Indemnitee (other than Lessor)
      under the Lease are given to Lessor on behalf of that Indemnitee, and each
      Indemnitee is an express third party beneficiary thereof.

15.11 Counterparts

      The Lease (including the Aircraft Lease Agreement and this CTA) may be
      executed in two or more counterparts, each of which shall be deemed an
      original, but all of which together shall

                                      58
<PAGE>

      constitute one and the same instrument. To the extent, if any, that the
      Lease constitutes chattel paper (as such term is defined in the UCC as in
      effect in any applicable jurisdiction), no security interest in the Lease
      may be created through the transfer or possession of any counterpart other
      than the original counterpart, which shall be identified as the
      counterpart designated as the "original" on the signature page of the
      Aircraft Lease Agreement by GE Capital Aviation Services.

15.12 Language

      All notices to be given under the Lease will be in English. All documents
      delivered to Lessor pursuant to the Lease (including any documents to be
      delivered pursuant to the Conditions Precedent) will be in English.

16.   DISCLAIMERS AND WAIVERS

      LESSOR AND LESSEE AGREE THAT THE DISCLAIMERS, WAIVERS AND CONFIRMATIONS
      SET FORTH IN SECTIONS 16.1 TO 16.4 BELOW SHALL APPLY AT ALL TIMES DURING
      THE TERM. LESSEE'S ACCEPTANCE OF THE AIRCRAFT IN ACCORDANCE WITH SECTION
      4.3 SHALL BE CONCLUSIVE EVIDENCE THAT LESSEE HAS FULLY INSPECTED THE
      AIRCRAFT AND EVERY PART THEREOF AND THAT THE AIRCRAFT, THE ENGINES, THE
      PARTS AND THE AIRCRAFT DOCUMENTS AND RECORDS ARE TECHNICALLY ACCEPTABLE TO
      LESSEE AND, EXCEPT AS EXPRESSLY SET FORTH IN THE CERTIFICATE OF TECHNICAL
      ACCEPTANCE, SATISFY THE DELIVERY CONDITION REQUIREMENTS AND ARE IN
      SUITABLE CONDITION FOR DELIVERY TO AND ACCEPTANCE BY LESSEE.

           TRADE) WITH RESPECT TO THE AIRCRAFT, ANY ENGINE OR ANY PART OR ANY
           SERVICES PROVIDED BY LESSOR UNDER THE LEASE; AND

     (B)   LESSOR SHALL NOT HAVE ANY OBLIGATION OR LIABILITY WHATSOEVER TO
           LESSEE (WHETHER ARISING IN CONTRACT OR IN TORT, AND WHETHER ARISING
           BY REFERENCE TO NEGLIGENCE, MISREPRESENTATION OR STRICT LIABILITY OF
           LESSOR OR OTHERWISE) FOR:

           (i)   ANY LIABILITY, LOSS OR DAMAGE CAUSED OR ALLEGED TO BE CAUSED
                 DIRECTLY OR INDIRECTLY BY THE AIRCRAFT OR ANY ENGINE OR BY ANY
                 INADEQUACY THEREOF OR DEFICIENCY OR DEFECT THEREIN OR BY ANY
                 OTHER CIRCUMSTANCE IN CONNECTION THEREWITH;

           (ii)  THE USE, OPERATION OR PERFORMANCE OF THE AIRCRAFT OR ANY RISKS
                 RELATING THERETO;

           (iii) ANY INTERRUPTION OF SERVICE, LOSS OF BUSINESS OR ANTICIPATED
                 PROFITS OR ANY OTHER INDIRECT OR CONSEQUENTIAL LOSS OR DAMAGES;

                THE AIRCRAFT, ANY ENGINE OR ANY PART.

     LESSEE HEREBY WAIVES, AS BETWEEN ITSELF AND LESSOR, ALL ITS RIGHTS IN
     RESPECT OF ANY CONDITION, WARRANTY OR REPRESENTATION, EXPRESS OR IMPLIED,
     ON THE PART OF LESSOR AND ALL CLAIMS AGAINST LESSOR HOWSOEVER AND WHENEVER
     ARISING AT ANY TIME IN RESPECT OF OR OUT OF ANY OF THE MATTERS REFERRED TO
     IN SECTION 16.1.

Re:  Boeing model 737-700 aircraft with manufacturer's serial number 30051 and
     United States nationality and registration marks (the "Aircraft")
     -------------------------------------------------------------------------


Ladies and Gentlemen:


     This letter confirms that we filed with the Federal Aviation Administration
(the "FAA") today at [__:__ ], the Aircraft Lease Agreement dated as of
September [__], 1999 (the "Lease") between General Electric Capital Corporation
as lessor (the "Lessor") and Midway Airlines Corporation as lessee, to which was
attached Lease Supplement No. 1 dated [__________], [____] (the "Lease
Supplement") covering the Aircraft and the General Electric model CFM56-7B24
aircraft engines with manufacturer's serial numbers [_______] and [________]
(the "Engines").

     Based upon our examination of the above described Instruments and of such
records of the FAA as we deemed necessary to render this opinion and as were
made available to us by the FAA, it is our opinion that:

                                     14-1
<PAGE>

     (a)  the Lease with the Lease Supplement attached is in due form for
            recordation by and has been duly filed for recordation with the FAA
            pursuant to and in accordance with the provisions of Section 44107
            of Title 49 of the United States Code;

     (b)  legal title to the Aircraft is vested in the Lessor and the Aircraft
            is duly registered in the name of the Lessor pursuant to and in
            accordance with the provisions of Section 44102 and 44103 of Title
            49 of the United States Code; and

     (c)  the Aircraft and the Engines are free and clear of all liens, security
            interests and encumbrances of record with the FAA other than such as
            are created by the Lease, as supplemented by the Lease Supplement.

     No opinion is herein expressed as to laws other than the federal laws of
the United States.  Since our examination was limited to records maintained by
the FAA Aircraft Registry, our opinion does not cover liens which are perfected
without the filing of notice thereof with the FAA, such as federal tax liens,
liens arising under Section 1368(a) of Title 29 of the United States Code and
possessory artisans' liens, and was subject to the accuracy of FAA personnel in
the filing, indexing and recording of instruments filed with the FAA and in the
search for encumbrance cross-reference index cards for the Engines.


                                    Very truly yours,

     [*] Lessee acknowledges and agrees that it is not located in the
     State of New York within the meaning of Section 7-101 1-c(b) of the New

     year recovery period, switching to the straight-line method for the first
     taxable year of the Indemnitee during the term for

     *    CONFIDENTIAL TREATMENT REQUESTED

                                      B-2
<PAGE>

     which such method yields a larger allowance, (c) assuming salvage value is
     zero, and (d) using a half-year convention.

     SPECIAL TAX INDEMNITY:

     MACRS Deductions Indemnity

     Lessee will on demand pay and indemnify each Tax Indemnitee for any loss,
     disallowance, or deferral of, or delay in claiming the MACRS Deductions
     resulting from Lessee's using the Aircraft in such a manner as to cause the
     Aircraft to be treated as "used predominantly outside the United States"
     within the meaning of Section 168(g) of the Code (hereinafter referred to
     as a "MACRS Loss").  In determining the indemnity required in connection
     with a MACRS Loss to the Tax Indemnitee under this Clause, the Tax
     Indemnitees shall be assumed to be subject to a combined U.S. and state
     income tax rate of (after giving effect to the deductibility of such state
     income taxes for U.S. income tax purposes) 38% in 1999 and in each year
     thereafter (the "Assumed Tax Rate"), and the Tax Indemnitee will have
     sufficient taxable income to be taxed at the Assumed Tax Rate after full
     utilization of the MACRS Deductions.  The amount payable under this
     indemnity shall be the amounts required from time to time, which, after
     deduction by the Tax Indemnitee of the amount of all additional U.S.,
     state, local, and foreign taxes required to be paid by Tax Indemnitee in
     respect of the receipt or accrual of such amount, will equal the increase
     in income taxes payable by (or not refundable to) Tax Indemnitee as the
     result of such MACRS Loss, plus the amount of any actual interest,
     penalties, and additions to tax payable by Tax Indemnitee with respect to
     such MACRS Loss.

     If, as the result of a MACRS Loss, the amount of the U.S. income taxes
     payable by an Tax Indemnitee for any taxable year shall be less than the
     amount of such taxes that would have been payable by the Tax Indemnitee had
     such MACRS Loss not occurred (or as the result thereof, an Tax Indemnitee
     shall receive a refund of U.S. income taxes payable that shall be greater
     than the amount of such refund , if any, that the Tax Indemnitee would have
     received had such MACRS Loss not occurred), then such Tax Indemnitee shall
     pay to the Lessee the amount of such increased reduction in taxes (or
     refund, including any actual interest (net of any taxes payable with
     respect to such interest) received thereon), plus any net additional U.S.,
     state, local, or foreign tax benefits actually realized by the Tax
     Indemnitee as the result of any payment made pursuant to this sentence
     (such reduction in, or increased refund of, income taxes to be determined
     on a hypothetical basis, i.e., assuming the Tax Indemnitee can utilize any
     additional tax benefits resulting from the MACRS Loss at the Assumed Tax
     Rate); provided, however, that the amount payable by the Tax Indemnitee
     pursuant to this sentence shall not exceed the sum of the amounts
     previously paid by the Lessee to the Tax Indemnitee pursuant to the
     preceding paragraph with respect to such MACRS Loss to the extent not
     previously taken into account under this sentence.

     The Supplemental Rent payable will be determined with reference to the

     [*] Lessee acknowledges and agrees that it is not located in the
     State of New York within the meaning of Section 7-101 1-c(b) of the New

     Aircraft pursuant to Section 168(b) of the Internal Revenue Code of 1986,
     as amended (the "Code"), commencing in 1999, computed (a) on the basis that
     the Aircraft is "7-year property" within the meaning of Section 168(e) of
     the Code), (b) by using the 200% declining balance method over a seven (7)
     year recovery period, switching to the straight-line method for the first
     taxable year of the Indemnitee during the term for

* CONFIDENTIAL TREATMENT REQUESTED

                                      B-2
<PAGE>

     which such method yields a larger allowance, (c) assuming salvage value is
     zero, and (d) using a half-year convention.

     SPECIAL TAX INDEMNITY:

     MACRS Deductions Indemnity

     Lessee will on demand pay and indemnify each Tax Indemnitee for any loss,
     disallowance, or deferral of, or delay in claiming the MACRS Deductions
     resulting from Lessee's using the Aircraft in such a manner as to cause the
     Aircraft to be treated as "used predominantly outside the United States"
     within the meaning of Section 168(g) of the Code (hereinafter referred to
     as a "MACRS Loss").  In determining the indemnity required in connection
     with a MACRS Loss to the Tax Indemnitee under this Clause, the Tax
     Indemnitees shall be assumed to be subject to a combined U.S. and state
     income tax rate of (after giving effect to the deductibility of such state
     income taxes for U.S. income tax purposes) 38% in 1999 and in each year
     thereafter (the "Assumed Tax Rate"), and the Tax Indemnitee will have
     sufficient taxable income to be taxed at the Assumed Tax Rate after full
     utilization of the MACRS Deductions.  The amount payable under this
     indemnity shall be the amounts required from time to time, which, after
     deduction by the Tax Indemnitee of the amount of all additional U.S.,
     state, local, and foreign taxes required to be paid by Tax Indemnitee in
     respect of the receipt or accrual of such amount, will equal the increase
     in income taxes payable by (or not refundable to) Tax Indemnitee as the
     result of such MACRS Loss, plus the amount of any actual interest,
     penalties, and additions to tax payable by Tax Indemnitee with respect to
     such MACRS Loss.

     If, as the result of a MACRS Loss, the amount of the U.S. income taxes
     payable by an Tax Indemnitee for any taxable year shall be less than the
     amount of such taxes that would have been payable by the Tax Indemnitee had
     such MACRS Loss not occurred (or as the result thereof, an Tax Indemnitee
     shall receive a refund of U.S. income taxes payable that shall be greater
     than the amount of such refund , if any, that the Tax Indemnitee would have
     received had such MACRS Loss not occurred), then such Tax Indemnitee shall
     pay to the Lessee the amount of such increased reduction in taxes (or
     refund, including any actual interest (net of any taxes payable with
     respect to such interest) received thereon), plus any net additional U.S.,
     state, local, or foreign tax benefits actually realized by the Tax
     Indemnitee as the result of any payment made pursuant to this sentence
     (such reduction in, or increased refund of, income taxes to be determined
     on a hypothetical basis, i.e., assuming the Tax Indemnitee can utilize any
     additional tax benefits resulting from the MACRS Loss at the Assumed Tax
     Rate); provided, however, that the amount payable by the Tax Indemnitee
     pursuant to this sentence shall not exceed the sum of the amounts
     previously paid by the Lessee to the Tax Indemnitee pursuant to the
     preceding paragraph with respect to such MACRS Loss to the extent not
     previously taken into account under this sentence.
