                        WESTERN PACIFIC AIRLINES, INC.

                        NOTES TO FINANCIAL STATEMENTS

1. PREPARATION OF FINANCIAL STATEMENTS

     The  accompanying  financial  statements  are  unaudited  and  reflect  all
adjustments  (consisting only of normal recurring adjustments) which are, in the
opinion  of  management,  necessary  for a fair  presentation  of the  financial
position and operating  results for the interim  periods.  The  organization and
business of Western Pacific Airlines, Inc. (the "Company"),  accounting policies
followed by the Company, and other information are contained in the notes to the
Company's audited financial  statements filed as part of the Company's  December
31, 1996 Annual  Report on Form 10-K.  This  quarterly  report should be read in
conjunction  with such annual  report.  The results of  operations  for the nine
months ended September 30, 1997 may not necessarily be indicative of the results
for the entire fiscal year ending December 31, 1997.

2. CHAPTER 11 REORGANIZATION

     On October 5, 1997,  the Company filed a petition (the "filing") for relief
under Chapter 11 of the U.S.  Bankruptcy  Code (the "Code") in Denver,  Colorado
(Case No. 97-24701-SBB). Under Chapter 11, certain claims against the Company in
existence  prior to the filing of the  petition  for relief are stayed while the
Company continues business operations as debtor-in-possession.

     In the Chapter 11 case, substantially all liabilities as of the date of the
filing are subject to resolution under a plan of  reorganization to be developed
and voted upon by the Company's creditors and confirmed by the Bankruptcy Court.
Schedules have been filed by the Company with the Bankruptcy Court setting forth
the assets and  liabilities of the Company as of the date of the filing as shown
by the Company's  accounting  records.  Differences between amounts shown by the
Company and claims filed by creditors  will be  investigated  and resolved.  The
ultimate amount and settlement  terms for such liabilities are subject to a plan
of  reorganization  as yet to be developed,  and accordingly,  are not presently
determinable.

     Under  the  Code,  the  Company  may  elect to  assume  or  reject  leases,
employment  contracts,  service  contracts,  and  other  executory  pre-petition
contracts,  subject to Bankruptcy  Court review.  The Company  cannot  presently
determine or reasonably  estimate the ultimate  liability  which may result from
the filing of claims for any rejected  contracts and no provisions have yet been
made for these items.

     The  Bankruptcy  Court has authorized the Company to use the cash generated
by its  operations  to continue to fund its business  obligations  on an interim
basis,  and to pay  necessary  operating  costs.  The various  Bankruptcy  Court
rulings  authorize the Company to use cash so that it can conduct its operations
on an interim basis. The Company expects to fund its working capital and capital
expenditure  requirements  through cash generated by the Company's receipts from
operations, sales of assets, and through debtor-in-possession credit facilities.
However,  there can be no assurance that the Company will be able to obtain such
debtor in possession  credit  facilities or, if obtained,  that such  facilities
will be sufficient to enable the Company to meet its liquidity requirements. The
Company's   financing   requirements  for  long-term   growth,   future  capital
expenditures,   and  debt  service   cannot  be  determined   until  a  plan  of
reorganization is developed and confirmed by the Bankruptcy Court.

     In the event that the Company is unable to obtain confirmation of a plan of
reorganization,  the Company may liquidate its business either in its Chapter 11
case or by converting its Chapter 11 case to a Chapter 7 liquidation.

3. COLLATERAL ACCOUNT

     On September  12, 1997,  the Company  borrowed the  principal  amount ("the
Note") of $10.0 million from Bank One, Texas, N.A. (the "Bank").  All amounts of
outstanding  principal and interest accrued on the note are due and payable upon
the earlier of (i) March 11, 1998, or (ii) within seven days of demand therefore
by the Bank.  Additionally,  all amounts of principal  outstanding  in excess of
$5.0 million were due and payable within seven days of the closing of the merger
between the Company and  Frontier  Airlines,  Inc.  (See Note 4). The Note bears


                                       6
<PAGE>

interest at the  Company's  option,  at either (i) the Bank's prime rate or (ii)
the Bank's Eurodollar rate plus one and one eighth percent (1.125%).  Actions to
collect on the note are stayed by the Chapter 11 proceedings.

     Hunt  Petroleum   Corporation  ("HPC"),  the  parent  corporation  of  Hunt
Petroleum of Texas,  Inc.  ("HPTI"),  a stockholder of the Company,  (i) entered
into a guaranty ("Guaranty"), whereby it guaranteed the repayment of all amounts
owing  under  the  Note,  and (ii)  entered  into an  indemnification  agreement
("Indemnification  Agreement")  whereby it agreed to indemnify  the Bank for any
liabilities  that might arise in connection with the Note. GFI Company  ("GFI"),
another stockholder of the Company,  entered into a contribution  agreement with
HPC, whereby it agreed to contribute 50% of all amounts payable by HPC under the
Guaranty or Indemnification  Agreement.  In addition, the Company entered into a
reimbursement  agreement  with  HPC and  GFI,  whereby  the  Company  agreed  to
reimburse  HPC or GFI,  as the case may be, for any  amounts  incurred  and paid
under the Guaranty or the Indemnification Agreement.

     As security for the Note,  the Company  entered  into a security  agreement
with the Bank,  whereby it granted the Bank a security interest in certain trade
accounts  receivable.  A further security interest was granted to HPC and GFI in
the  same  trade  accounts  receivable  and in  the  Company's  interest  in the
satellite  airport  terminal  at the  Colorado  Springs,  Colorado  airport.  In
addition,  the  Company  agreed to assign  certain  payments  relating  to trade
accounts receivable to (i) the Bank and (ii) HPC and GFI.

     As  consideration  for the Guaranty  and the  Contribution  Agreement,  the
Company entered into a registration  rights  agreement with GFI and HTPI.  Under
the registration rights agreement, the Company agreed to register on demand: (i)
all shares of the  Company's  common stock  currently  owned by GFI or HPTI,  or
which HPTI or GFI has the right to acquire  upon the  exercise of any  warrants,
options,  or convertible  securities;  and (ii) any additional  shares of Common
Stock HPTI or GFI may acquire  from (i) the  Company,  (ii) an  affiliate of the
Company,  or (iii)  any  "joint  filer"  of HPTI or GFI,  as the case may be, as
determined  for purposes of Section 13(d) under the  Securities  Exchange Act of
1934,  as amended,  for a period of five (5) years  commencing  on September 11,
1997 and ending on September 11, 2002.  Any securities of the Company which were
previously  subject  to  registration  rights on the part of HPTI or GFI are not
subject to the registration rights agreement.

4. TERMINATION OF MERGER

     On June 30, 1997, the Company entered into a definitive  agreement and plan
of merger with Frontier Airlines, Inc. ("Frontier"),  pursuant to which Frontier
would merge with and into the  Company,  with Western  Pacific as the  surviving
corporation  after the merger.  Also, on June 30, 1997, the Company and Frontier
entered into a code share Agreement which became effective on August 1, 1997. On
September  29, 1997,  Western  Pacific and  Frontier  announced in a joint press
release that the parties had  terminated  the agreement and plan of merger.  The
two  companies  also  announced  the  termination  of their  current  code share
agreement, effective November 16, 1997. The reasons cited for the termination of
the merger were the amount of time involved in  consummating  the merger and its
toll on employee morale, financial performance, and operations of both airlines.
Cultural  differences  and the  contrast in  scheduling  philosophies  were also
noted.

5. NON-RECURRING CHARGES

     The Company  incurred  $8.8 million in  non-recurring  charges in the three
months  ended  September  30, 1997.  These  charges  relate to the  write-off of
certain  capitalized costs relating to facilities in Colorado  Springs,  such as
the auxiliary  concourse at the Colorado  Springs  airport,  its investment in a
maintenance hangar at Colorado Springs,  leasehold  improvements at the Colorado
Springs airport and at the Company's headquarters building; costs related to the
terminated merger with Frontier; costs related to certain software whose use has
been discontinued;  estimated loss on the sale of an aircraft; and investment in
Colorado Springs Car Rental, Inc., a Thrifty car rental franchisee. For the nine
months  ended  September  30,  1997,  the  Company  incurred  $12.2  million  in
non-recurring charges,  including the charges noted above, plus certain one-time
costs  related to the move of the Company's  operations to Denver  International
Airport  ("DIA");  write-off  of  deposits  for a bus  shuttle to be used at the
Company's  Colorado Springs  airport;  and certain costs related to new uniforms
for the in-flight department.

OVERVIEW

        On June 30, 1997,  the Company  entered into a definitive  agreement and
plan of merger with  Frontier  Airlines,  Inc.  ("Frontier"),  pursuant to which
Frontier  would  merge  with and  into the  Company,  with  the  Company  as the
surviving  corporation after the merger. Also, on June 30, 1997, the Company and
Frontier entered into a code-share agreement which became effective on August 1,
1997. On September 29, 1997,  Western Pacific and Frontier  announced in a joint
press release that the parties had  terminated the agreement and plan of merger.
The two companies  also announced the  termination  of their current  code-share
agreement, effective November 16, 1997. The reasons cited for the termination of
the merger were the amount of time involved in  consummating  the merger and its
toll on employee morale, financial performance, and operations of both airlines.
Cultural  differences  and the  contrast in  scheduling  philosophies  were also
noted.

     On October 3, 1997,  four directors of the Company  resigned from its Board
of  Directors.   The  resigning   directors  included  Ivan  Irwin,  Jr.,  Glenn
Stinchcomb,  Clayton I.  Bennett,  and James R.  Wikert.  In  addition,  Messrs.
Bennett and Wikert also  resigned  from the Board of Directors of the  Company's
subsidiary,  Mountain Air Express,  effective October 3, 1997. The reasons cited
for the resignation  were potential  conflicts of interest between the Directors
and their other business interests.

     On October 5, 1997,  the Company  filed a petition for relief under Chapter
11 of the Code in Denver,  Colorado.  The filing  enabled  the Company to obtain
protection from creditors in order to conduct its operations while attempting to
develop a reorganization  plan and seeking  financing  necessary to fund it. The
Bankruptcy  Court has  authorized  the Company to use the cash  generated by the
Company to fund its business  obligations on an interim basis. While the Company
would have preferred to reorganize its  operations  without  resorting to filing
for bankruptcy  protection,  it viewed the filing as the only viable alternative
given the adverse impact on the business of inadequate liquidity. The Company is
actively  seeking  debtor-in-possession   financing  to  assist  it  in  funding
operations and ultimately a plan of reorganization.

   The Company  commenced  operations on April 12, 1994 as a  development  stage
enterprise  organized to operate a low-fare,  medium-haul,  scheduled  passenger
airline from its hub at the Colorado Springs  Airport.  The Company began flight
operations on April 28, 1995 with two Boeing  737-300  aircraft and provided six
daily  round-trips  between  Colorado Springs and five cities.  Thereafter,  the
Company  continued  to add  aircraft  and cities and on June 29,  1997,  moved a
significant portion of its operation to Denver International Airport ("DIA"). On
October 10, 1997,  Western Pacific announced that it was terminating jet service
into and out of Colorado  Springs,  effective October 20, 1997. After that date,
air  service  between  Colorado  Springs  and DIA would be  provided  by Western
Pacific's code-share partner,  Mountain Air Express, on turboprop aircraft. This
announcement  also  included  the  termination  of  service to  Houston,  Texas,
effective  October  20,  1997 and the  termination  of service to  Indianapolis,
Indiana,  effective  November  16,  1997.  The  following  chart  indicates  the
Company's changes in service since December 31, 1996.

The Company has previously announced that on November 16, 1997, it will withdraw
service to Indianapolis and terminate the code-share agreement with Frontier.

     During 1996, the Company assisted in the start-up of an affiliated regional
carrier,  Mountain  Air  Express,  ("MAX"),  to  carry  traffic  into and out of
Colorado  ski markets  and other  smaller  travel  markets  that cannot  support
frequent jet service.  MAX, which  commenced  flight  operations on December 15,
1996, is a separate  operating  company with its own operating  certificate  and
management.  The Company  owns 57% of  outstanding  stock of MAX.  MAX filed for
protection under Chapter 11 of the Code on November 6, 1997 in Denver,  Colorado
(Case #97-26584-SBB).

RESULTS OF OPERATIONS

WESTERN PACIFIC AIRLINES

OPERATING REVENUES

   Airline revenue is primarily a function of the number of passengers flown and
the fares  charged by the  airline.  Passenger  ticket sales are  recognized  as
revenue when the  transportation is provided.  The Company's fares are generally
non-refundable.  Prior to  completing  the  total  conversion  of the  Company's
reservations to the SABRE computerized  reservations system ("CRS") on April 25,
1997,  changes in travel plans could only be made prior to  scheduled  departure
for a $50 change fee,  plus any fare  increase.  After the  conversion to SABRE,
tickets not used remain a liability of the airline,  until used to pay for other
flights  or until the  ticket  expires,  generally  after  one  year. 

   The chart  presented  below  compares the Company's  passenger load factor to
the  incremental  growth in capacity as measured by available  seat miles (ASM).
The airline  industry is  extremely  seasonal,  with the  highest  load  factors
typically  occurring in the summer months, and the lowest load factors occurring
during September,  October, January, February, April and May. The Company's load
factor decreased 3.4 percentage  points for the quarter ended September 30, 1997
from the quarter ended June 30, 1997, due to a combination of factors  including
the  37.3%  increase  in  capacity  and  issues  with  the  Frontier  code-share
agreement.  The  Company's  load factor  increased  3.8  percentage  points when
comparing  the quarter ended  September 30, 1997 to the quarter ended  September
30, 1996. This increase can be attributed to the effects of shifting most of the
Company's  operations  to the  larger  DIA  hub on  June  29,  1997;  aggressive
promotions  such as "Peak Paks",  and a promotion with King Soopers,  a Colorado
grocery  store  chain;   and  increased   frequencies  to  increase   connecting
opportunities.

</TABLE>

   Passenger  revenue per revenue passenger mile (RPM) or yield may increase due
to a combination of factors,  including increases in average fares and decreases


                                       9
<PAGE>

in discounted fares as a percentage of total fares. However, in periods when the
Company introduces promotional fares in new markets or uses promotional fares to
stimulate   additional  travel  in  existing  markets,   the  Company  generally
experiences a decrease in passenger  revenue per RPM. The Company  believes that
the  negative  impact of entering  new markets and the use of  discounted  fares
should  decrease as the Company  increases its overall revenue base and customer
awareness.  For the quarter  ended  September 30, 1997,  the Company  produced a
yield of 9.45(cent)  which is a 14.2% increase from the prior quarter  primarily
as a result  of the move of most of the  Company's  operations  to DIA,  and the
expanded schedule which allows more connecting opportunities.

   The Company's operating  break-even load factor during the twenty nine months
of its  operations has fallen from a high of 104.8% in May 1995 to 58.7% for the
quarter ended  September  30, 1996.  Historically,  as the  Company's  fleet has
expanded,  the  incremental  passenger  revenue  generated  from the  additional
capacity  has  covered  the  incremental  costs of the  expansion,  as well as a
portion of the Company's existing fixed costs,  resulting in a steady decline in
the  operating  break-even  load  factor.  The  Company's  cost  per  ASM  after
non-recurring  charges for the quarter ended  September 30, 1997  increased from
the prior quarter, while the cost per ASM before these non-recurring charges was
6.88(cent)  for the quarter ended  September 30, 1997, a decrease from the prior
quarter's cost per ASM before non-recurring charges of 7.09(cent). This decrease
is a function of the 37.7% increase in ASMs over the quarter ended September 30,
1997 from the prior  quarter.  There can be no  assurance  that any  incremental
passenger  revenue generated in the future as the Company expands its fleet will
be sufficient to cover  incremental  costs or that,  ultimately,  as a result of
these or other  factors,  the Company's  operating  break-even  load factor will
decrease.

MOUNTAIN AIR EXPRESS

     Mountain Air Express  commenced flight operations on December 15, 1996. The
determination  of MAX's  revenues  had been  governed by an  Alliance  Agreement
between  MAX and the  Company  and the  number of  passengers  flown.  Under the
Alliance Agreement,  all of MAX's marketing,  scheduling,  and pricing decisions
were made by the  Company.  In return,  MAX  received an agreed  amount from the
Company for each passenger flown. The Alliance Agreement between the Company and
Mountain Air Express is in the process of being rejected by the Company pursuant
to a court order by the United States  Bankruptcy  Court.  Effective October 22,
1997, MAX is paid $200,000 per week to fly the Company's  connecting  passengers
between  Colorado  Springs and DIA,  and will be paid a pro rate  portion of the
passenger  fare for  passengers  connecting in other  cities.  MAX's load factor
increased for the quarter ended September 30, 1997 as compared to prior quarters
due to the Company's  transfer of some of their service to Oklahoma City, Tulsa,
and  Kansas  City to MAX,  and the  larger  Denver  marketplace.  MAX  filed for
protection under Chapter 11 of the Code in Denver, Colorado on November 6, 1997.

</TABLE>

   All costs shown above have been adjusted by $8.8 million for the three months
ended  September 30, 1997 and $12.2 million for the nine months ended  September
30, 1997 for  non-recurring  charges  related to the  Company's  termination  of
service to various cities,  primarily  Colorado  Springs,  and one-time costs of
commencing service at Denver International Airport.

   Salaries,  wages  and  benefits  decreased  by .05  cents  per ASM or 5% when
comparing  the quarter ended  September 30, 1997 to the quarter ended  September
30, 1996. This decrease can be attributed to a 36% increase in ASMs, with only a
25% increase in full-time  equivalent  personnel  (FTE).  Salaries,  wages,  and
benefits  decreased  by .06 cents per ASM or 5% when  comparing  the nine months
ended  September  30, 1997 to the nine months ended  September  30,  1996.  This
decrease can also be  attributed  to the increase in ASMs over the period noted,
with a proportionally smaller increase in FTEs.

   Aircraft  lease  expense  decreased .32 cents per ASM, or 20% for the quarter
ended September 30, 1997 from the quarter ended September 30, 1996. The decrease
is due to the wet lease of two Boeing 727 aircraft during the period of mid-June
through  September 5, 1996 which increased the Company's cost for the quarter by
 .30 cents per ASM for this quarter which did not occur in 1997.  Aircraft  lease
expense  decreased .22 cents per ASM, or 14% for the nine months ended September
30, 1997 when  comparing  the nine months ended  September  30, 1997 to the nine
months  ended  September  30,  1996.  This  decrease  is due to the  wet  leases
described  above as well as the 32%  increase in ASMs for the nine months  ended
September  30, 1997 from the nine  months  ended  September  30, 1996 with a 27%
increase in the number of leased aircraft over the comparable periods.

     Aircraft  fuel and oil  expense  decreased  by .08 cents per ASM or 7% when
comparing  the quarter ended  September 30, 1997 to the quarter ended  September
30, 1996. This decrease  reflects the effect of a 5.3 cent per gallon or 7% fuel


                                       11
<PAGE>

price decrease over the period.  Aircraft fuel and oil expense  decreased by .01
cents per ASM or 1% when  comparing the nine months ended  September 30, 1997 to
the nine months ended  September 30, 1997, on a decrease of 1.1 cents per gallon
over the same time period.

     Other rentals,  landing,  airport and ground handling fees increased by .40
cents per ASM or 69% when comparing the quarter ended  September 30, 1997 to the
quarter ended  September 30, 1996.  This increase was primarily due to increased
flight  simulator  rental time due to increased hiring of pilots required by the
higher utilization  schedule,  and increased ground handling,  rent, and landing
fees at DIA. Other rental,  landing,  airport and ground handling fees increased
by .13 cents per ASM or 20% when  comparing the nine months ended  September 30,
1997 to the nine months ended  September 30, 1996.  This increase was due to the
increased  simulator  rental  time  previously  noted,  both  for the  increased
utilization  schedule,  and for new aircraft deliveries that occurred during May
and June 1997.

     Advertising  expense  decreased by .23 cents per ASM or 82% when  comparing
the quarter ended  September  30, 1997 to the quarter ended  September 30, 1996.
This decrease was intentional,  due to the large amount of advertising placed in
the second quarter when the Company began service to Denver. Advertising expense
decreased  by .14  cents per ASM or 41% when  comparing  the nine  months  ended
September  30, 1997 to the nine  months  ended  September  30,  1996,  after the
deduction of $1.8 million in launch  advertising  related to the commencement of
the Company's  operations at DIA. Without this adjustment,  advertising cost per
ASM for the nine months ended September 30, 1997 was .27 cents per ASM, or a 21%
reduction from the comparable period in 1996. This reduction was due to the cost
of advertising for seven new cities for which service was added during the first
nine months of 1996, with only one city (Denver) added during 1997.

     Insurance  expense decreased by .02 cents per ASM or 12% when comparing the
quarter ended  September 30, 1997 to the quarter ended  September 30, 1996,  and
 .07 cents per ASM or 32% when comparing the nine months ended September 30, 1997
to the nine months ended  September 30, 1996.  This decrease  reflects a premium
reduction  obtained  by the  Company  due to  fewer  aircraft  in  service  than
originally projected for the policy year.

   Maintenance  materials and repairs expense  increased by .25 cents per ASM or
69% when  comparing  the quarter  ended  September 30, 1997 to the quarter ended
September 30, 1996, and .36 cents per ASM or 103% when comparing the nine months
ended  September  30, 1997 to the nine months ended  September  30,  1996.  This
increase reflects the amortization of airframe "C" maintenance checks and engine
overhauls  performed on the Company's  fleet,  as well as a shorter  maintenance
cycle due to the Company's increased aircraft utilization.  The Company uses the
deferral  method of accounting  for "C" check  maintenance  and engine  overhaul
costs.

   Agency  and  cargo  commissions  increased  by .14  cents per ASM or 64% when
comparing  the quarter ended  September 30, 1997 to the quarter ended  September
30,  1996,  and .09 cents per ASM or 43% when  comparing  the nine months  ended
September 30, 1997 to the nine months ended  September 30, 1996. As anticipated,
agency and cargo commissions increased as a percentage of total expenses, as the
Company  entered into  agreements  with several of the  industry's  computerized
reservation  systems  ("CRS")  in March of 1997 so that  seats on the  Company's
flights could be booked directly by a travel agent without the need to telephone
the Company's  reservation  office.  These  agreements  have given the Company's
flights  increased  exposure  to travel  agents,  who now account for 60% of the
Company's flight booking activity.

   Depreciation  and  amortization  decreased  .04  cents  per  ASM or 22%  when
comparing  the quarter ended  September 30, 1997 to the quarter ended  September
30, 1996; and remained at .17 cents per ASM when comparing the nine months ended
September 30, 1996 to the nine months ended  September 30, 1995. The increase in
ASMs was  directly  proportional  to the increase in assets for the nine months,
while the increase in ASMs for the quarter  ended  September 30, 1997 was larger
than the increase in assets.

   Other operating expenses increased by .59 cents per ASM or 89% when comparing
the quarter ended September 30, 1997 to the quarter ended September 30, 1996 and
 .44 cents per ASM or 65% when comparing the nine months ended September 30, 1997
to the nine months ended September 30, 1996. Excluded from this calculation were
one time charges  related to the write-off of  capitalized  costs related to the
merger with Frontier,  capitalized  facility costs in Colorado Springs, one time
charges related to the commencement of operations at DIA, new uniforms,  and the
write-off  of  deposits  made on  trams  originally  intended  to be used at the
auxiliary  concourse  at Colorado  Springs.  Other  operating  expenses  include
property  taxes,  telecommunication  and  utilities  charges,  professional  and
consulting   services,   supplies  and  minor  equipment   (excluding   aircraft
maintenance supplies), credit card processing fees, bad debt expense, travel and


                                       12
<PAGE>



                                      


incidental expense,  and passenger  reaccomodation and baggage delivery charges.
While some of these  costs,  such as credit  card  processing  fees and bad debt
expense will vary with the increase in ASM's,  others such as supplies will not.
Significant  increases or new charges in this category for the nine months ended
September  30, 1997 from the nine months ended  September  30, 1996 include $3.0
million for CRS fees;  $2.2 million for the  outsourced  Information  Technology
functions;  $3.3 million in  reaccommodation  charges  related to the  Company's
schedule changes and operational performance;  and $.5 million in payments to an
outside revenue accounting (ticket) processor.  The CRS fees and the expenses of
processing  revenue are additional  distribution  costs related to the Company's
move  into the  SABRE  multi-host  reservation  system,  and are  offset  by the
additional revenue generated as a result of the wider  distribution  system. The
fees paid to  reaccommodate  passengers  are expected to decrease as the Company
adjusts to its new flight schedule on November 16.

  The decrease in the cost per ASM for the quarter ended  September 30, 1997 can
be attributed to the 61% increase in ASM's from the prior quarter.

BALANCE SHEET FLUCTUATION ANALYSIS

     The Company's  accounts  receivable  increased by $11.3 million  during the
nine months  ended  September  30, 1997 due to $9.5 million due from the Airline
Clearing  House and $1.1  million due from the Airlines  Reporting  Corporation.
Both of these  receivables  are a reflection of the Company joining the CRSs and
the timing of the  payments  that are made.  The  Company's  aircraft and engine
reserves,  both current and long term, increased by $5.3 million during the nine
months ended  September  30, 1996.  These  reserves  reflect the increase in the
number of aircraft in the Company's fleet, as well as the increased utilization.
Property and  equipment  decreased by $6.7 million  during the nine months ended
September  30, 1997, as a result of the Company's  decision to  discontinue  jet
service to Colorado Springs and therefore, the Company wrote down certain assets
such as the hangar,  auxiliary concourse, and leasehold improvements at Colorado
Springs.

      The Company's  accounts payable increased by $15.4 million during the nine
months ended  September  30, 1997. As  previously  noted,  the Company filed for
Chapter 11 protection under the United States Federal Bankruptcy Code on October
5, 1997.

      The Company's  air traffic  liability  account  increased by $14.7 million
during  the nine  months  ended  September  30,  1996.  This  increase  resulted
primarily  from  advance  reservations  made for travel not yet taken due to the
increase in the number of flights from  December 31, 1996 to September  30, 1997
and promotions offered by the Company.

    LIQUIDITY AND CAPITAL RESOURCES

   During the nine months ended  September  30, 1997,  the  Company's  operating
activities  resulted  in a cash flow  deficit of $40.2  million,  which has been
funded  primarily  with short term  borrowings and funds raised from two private


                                       13
<PAGE>

placements  of preferred  stock.  At September 30, 1997 the Company had cash and
cash equivalents of $7.9 million, restricted cash of $5.6 million, and a working
capital deficit of $43.8 million. At December 31, 1996, the Company had cash and
cash  equivalents  of $12.1  million,  restricted  cash of $8.3  million,  and a
working capital deficit of $19.0 million.

   Cash flow used in investing  activities  totaled $.9 million  during the nine
months  ended  September  30,  1997,  of which $4.9  million was for new capital
expenditures, offset by $4.0 million in proceeds from a production deposit. Cash
flows from investing  activities totaled $35.1 million for the nine months ended
September  30,  1996,  consisting  primarily  of the  purchase  of a used Boeing
737-300 aircraft.

   At September 30, 1997, the Company operated nineteen aircraft,  with eighteen
under  operating  leases with terms of either five or ten years.  The  Company's
nineteenth  aircraft,  which it owned,  was sold by the  Company on  November 4,
1997, realizing net proceeds of approximately $5.4 million in cash from the sale
and a loss of $1.3  million  which is included in the third  quarter  loss.  The
Company  has entered  into an  agreement  with the new owner of the  aircraft to
continue to use the  aircraft  for one month.  The Company  has  negotiated  for
delivery of one  additional  used  aircraft in November  1997 and must decide if
delivery  will be  accepted  by November  21,  1997.  The Company is party to an
aircraft  purchase  agreement with the Boeing Company  providing for delivery of
two new Boeing 737-300 aircraft, one in December 1997 and the second in November
1998. The Company has tentatively  agreed to sell these delivery  positions to a
third party.  Additionally,  the Company  leases up to four spare engines at any
time under  operating  leases with terms  ranging from  several  months to three
years.

   Cash flow provided by financing activities totaled $37.0 million for the nine
months  ended  September  30, 1997 and $16.7  million for the nine months  ended
September 30, 1996. See Note 3 of Notes to the Consolidated Financial Statements
for a discussion of the collateral account.

   Under the Code,  the Company has the exclusive  right,  for 120 days from the
filing date, or until February 2, 1998, to present a reorganization  plan to the
Bankruptcy Court. This date may be extended by the Bankruptcy Court.  During the
60 day  period  from the filing  date,  no  payments  need to be made on real or
personal  property leases,  including  aircraft  leases,  except as specifically
agreed or ordered by the court.  With  respect  to  aircraft  and real  property
leases,  the  Company  must  commence  payments  at the end of the 60 day period
unless  otherwise agreed between the Company and the lessor.  Additionally,  the
contractual  payments  deferred under  aircraft  leases during the first 60 days
must  generally be brought  current  within the 60 day period for real  property
leases (unless  otherwise agreed) or by the later end of the 60 day period or 30
days from the due date of the  payment for  aircraft  leases  (unless  otherwise
agreed).  The Company  estimates  that its  aircraft  leases  alone will require
approximately  $10.1  million to be brought  current on  December  4, 1997.  The
Company is actively seeking  debtor-in-possession  ("DIP")  financing which will
allow  it  to  continue   operations   and  to  assist  in  funding  a  plan  of
reorganization.  If the Company is unable to secure such financing,  it may sell
assets  or find  other  financing  mechanisms  to  generate  cash.  There  is no
assurance  that the Company will be able to secure DIP financing or raise enough
funds to allow it to obtain  confirmation  of a plan of  reorganization.  If the
Company is unable to obtain  confirmation  of a plan,  the assets of the Company
will be liquidated.

OUTLOOK: ISSUES AND UNCERTAINTIES

     The following issues and uncertainties,  among others, should be considered
in evaluating the Company's future performance.

     EMERGENCE FROM BANKRUPTCY  PROTECTION.  The Company is currently  operating
under  protection of the Code. On or before the 60th day from the filing date of
October 5, 1997,  the Company  must agree to  commence  payments on its real and
personal  property  leases and bring most  payments  deferred  during the 60 day
period current at that time, unless otherwise agreed by the lessor.  The Company
has the exclusive  right for the first 120 days after the filing date to present
a reorganization plan which must thereafter be approved by the Bankruptcy Court.
The Company will likely  require  debtor-in-possession  financing to emerge from
Chapter 11  protection.  There can be no assurance  that such  financing will be
obtained or that if obtained, the amount will be sufficient to allow the Company
to continue operations.

     HISTORICAL  LOSSES.  The Company began scheduled flight operations on April
28, 1995.  During the period from the Company's  inception through September 30,
1997,  the Company  incurred net losses  totaling $92.0 million and has had only
two profitable  quarters in its history.  Given the Company's  limited operating
history,  there can be no assurances  that the Company will be profitable in the
future.

                                       14

     CONSUMER CONCERN ABOUT OPERATING SAFETY CONDITIONS AT START-UP AND BANKRUPT
CARRIERS.  The highly  publicized safety issues that led to the Federal Aviation
Administration (FAA) grounding of ValuJet have caused some consumers to question
the  operating  safety of all  start-up  airlines.  Though the Company  passed a
rigorous National  Aeronautical Safety Inspection audit conducted by the FAA and
passed an independently commissioned comprehensive safety audit conducted by the
Flight Safety Foundation,  there is no assurance that the FAA will not take more
restrictive  actions  against  the  Company  because  of its being in Chapter 11
bankruptcy  procedures.  Such actions by the FAA could increase  operating costs
and reduce future earnings potential.

   RISING FUEL COSTS. At the Company's  current  consumption rate, each one cent
increase in the price of fuel  increases the  Company's  monthly fuel expense by
approximately $40,000. Some carriers have begun to assess a fuel surcharge to be
added to their  base fares to cover  these  increased  costs.  The  Company  has
considered  this  alternative,  but there can be no  assurance  that the Company
would be able to pass along any increases in the price of fuel to its consumers.
Currently, the Company is prepaying for its fuel requirements with cash.

     UNIONIZATION OF EMPLOYEE GROUPS. The Company's  mechanics voted to join the
International  Brotherhood of Teamsters  union in May 1996. No other work groups
are currently represented by, or have voted to be represented by, a union. While
the mechanics'  action has not altered the Company's work rules or increased the
Company's  costs,  there can be no assurance that such action will not result in
future  changes  or  that  other  employee   groups  will  not  vote  for  union
representation,  nor that labor costs for those  groups  represented  by a union
will not increase.  The Company  currently has no contract with its mechanics or
any other labor group.

     COMPETITION.  The airline  industry is highly  competitive.  Other airlines
that presently  serve the Company's  routes in competition  with the Company are
larger and have greater name  recognition  and resources  than the Company.  The
Company may also face  competition  from other  airlines which may begin serving
the markets that the Company  currently  serves or may serve in the future,  and
competition  from new  low-cost  airlines  that may be formed to  compete in the
low-fare market (including those formed by other major airlines) and from ground
transportation   alternatives.   The   Company's   hub  is   located  at  Denver
International  Airport,  where  United  Airlines  presently  has 64%  (based  on
September 1997 enplanements) of the market.

     GENERAL  STATE OF UNITED  STATES  ECONOMY.  The airline  industry is highly
susceptible  to general  changes in the economic  climate,  particularly  in the
leisure travel segment of the market.  Any downturn in the economy of the United
States could have an adverse effect on the Company's business.

THIS LEASE AGREEMENT is made the     day of June 1997

BETWEEN:  WILMINGTON TRUST COMPANY,  a banking  corporation  organized under the
laws of the State of Delaware whose chief executive  office is located at Rodney
Square North, 1100 North Market Street, Wilmington,  Delaware 19890-0001, not in
its individual  capacity  except as otherwise  expressly  provided  herein,  but
solely as owner trustee (the "OWNER TRUSTEE"), as lessor (the "LESSOR")

and

WESTERN  PACIFIC  AIRLINES,  INC.,  a  company  incorporated  under  the laws of
Delaware  whose  principal  address  is at 2864 S.  Circle  Drive,  Suite  1100,
Colorado Springs, CO 80906, as lessee (the "LESSEE").

WHEREAS:

NBB  Stream  Lease  Co.,  Ltd.  has leased  the  Aircraft  to  Sunrock  Aircraft
Corporation  Limited  which,  pursuant to the head lease  assignment  (the "Head
Lease  Assignment"),  has assigned its rights but not its obligations  under the
Head Lease (as defined below) to Wilmington Trust Company,  as the Owner Trustee
and the Lessor  under this  Agreement.  The Lessee has  requested  the Lessor to
lease  the  Aircraft  to  the  Lessee  which  the  Lessor  has  agreed  to do in
consideration of, and subject to, the covenants,  terms and conditions contained
in this Agreement.

NOW IT IS HEREBY AGREED as follows:

1.    DEFINITIONS AND INTERPRETATION

1.1   DEFINITIONS

      In this  Agreement the  following  expressions  shall,  unless the context
      otherwise requires, have the following respective meanings:

      AFFILIATE                     in  relation  to  any  person,   any  entity
                                    controlled  directly or  indirectly  by that
                                    person, any entity that controls directly or
                                    indirectly that person,  or any entity under
                                    common  control with that  person.  For this
                                    purpose  "control"  of any  entity or person
                                    means  ownership of a majority of the voting
                                    power of the entity or person.

      AFTER-TAX BASIS               a basis  whereby any payment  required to be
                                    made on such basis shall,  if necessary,  be
                                    supplemented  by a further  payment  so that
                                    the  aggregate  of the two  payments,  after


                                       1
<PAGE>

                                    deduction  of all Taxes  resulting  from the
                                    receipt (actual or  constructive) or accrual
                                    of such  payments,  and  after  taking  into
                                    account all related Tax savings  (whether by
                                    relief,  deduction,   credit  or  otherwise)
                                    actually   realised  as  a  result  of  such
                                    payments,  shall be equal to the  payment so
                                    required.

      AGREED APPRAISER              a reputable aircraft appraisal  organization

          agreement  with that seller,  manufacturer  or  maintenance  performer
          (including,  without  limitation,  the Purchase  Agreement  and/or the
          Purchase Agreement  Assignment) unless the default arises from any act
          or omission of the Lessee  whether or not in  circumstances  entitling
          that seller,  manufacturer or maintenance  performer to terminate that
          agreement); or

      (b) any Excusable  Delay the Lessor delays in the delivery of, or fails to
          deliver, the Aircraft under this Agreement:

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

          (ii)the Lessee will not be entitled to terminate  this Agreement or to
              reject the Aircraft when  tendered for delivery by the Lessor,  on
              the grounds of any such delay;  provided that this Agreement shall
              automatically  terminate  upon  the  termination  of the  Purchase
              Agreement prior to the Delivery Date and the Lessee shall have the

              given or on the day before the Period of Extension commences.

      (b) In the event the Lessee does not exercise the Lessee Extension Option,
          the Lessor  shall have the option (the "LESSOR  EXTENSION  OPTION") to
          extend the Term for a period of  twenty-four  (24) months (the "PERIOD
          OF EXTENSION"),  provided that the Lessor shall give the Lessee notice

5.    PAYMENTS

5.1   AIRCRAFT COMMITMENT FEE

      Lessee  shall pay to the  Lessor a  Commitment  Fee in the  amount  and in
      accordance with the schedule set forth in Letter Agreement No. 1:

      The  Commitment  Fee shall be returned to the Lessee  five  Business  Days

      At the Lessor's option, payment of the Commitment Fee may take the form of
      the  provision  by the Lessee to the Lessor of a Letter of Credit,  and in
      such case,  the Lessor  agrees to exchange such Letter of Credit for a new
      Letter  of  Credit  in an  appropriately  reduced  amount  if and when the
      Commitment  Fee is reduced as provided in this Clause 5.1;  provided  that
      the Lessee shall have the right to maintain the Commitment Fee in the form
      of cash, subject to the conditions set forth in Clause 5.15(a).

          shall end on the last day of that month; and

          in advance on each Rent Date. Payment must be initiated  adequately in

          the payment on the Rent Date.

      (b) AMOUNT:  The Rent  payable in respect of each  Rental  Period  will be
          calculated as set forth in Letter Agreement No. 1.

          ("RELEVANT  PERIODS"),  the first of which will begin on the  Delivery
          Date  and  end on  the  date  immediately  preceding  the  numerically
          corresponding  day in the 6th calendar  month after the Delivery Date.
          Each  succeeding  Relevant  Period  shall be of six  months (6 months)
          duration  commencing  on  the  date  succeeding  the  last  day of the
          preceding  Relevant  Period,  save that if any  Relevant  Period would

              ("ENGINE LLP SUPPLEMENTAL RENT"); and

          (iv)in respect of the Landing Gear, the applicable amount set forth in
              Letter  Agreement  No.  1 for each  Flight  Hour  operated  by the

5.6   GROSS-UP

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

      (b) All Taxes (other than Lessor Taxes) in respect of payments  under this
          Agreement shall be for the account of the Lessee.

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

5.7   TAXATION

      (a) The Lessee will on demand pay and indemnify  each  Indemnitee  against
          all Taxes (other than Lessor Taxes) levied or imposed  against or upon
          the Indemnitee or the Lessee or on any payments to such  Indemnitee or
          imposed  against the Aircraft,  any Engine or any Part and relating to
          or  attributable  to the Lessee,  this Agreement or the Aircraft,  any
          Engine or any Part  directly  or  indirectly  in  connection  with the
          importation,   exportation,   registration,   abandonment,  ownership,
          leasing,  sub-leasing,  pooling, purchase, delivery,  possession, use,
          operation,  repair, condition,  maintenance,  modification,  overhaul,
          transportation,  landing, storage, presence,  transfer of title, other
          disposition  or  redelivery of the Aircraft or any part thereof or any
          rent,  receipts,  insurance proceeds,  income or other amounts arising
          therefrom or otherwise with respect to the  transactions  contemplated
          hereby and the performance by the parties under this Agreement and the
          related operative documents.

      (b) If an  Indemnitee  shall  actually  realize any Tax savings (by way of
          refund,  deduction or credit) in respect of any amount with respect to
          which the Lessee  shall  have made a payment  (or  increased  payment)
          pursuant to Clause 5.6,  5.10 or 8.4, or shall have  indemnified  such
          Indemnitee  pursuant  to  sub-clause  (a) above,  and such Tax savings
          shall not have been taken into account  previously in calculating  any
          indemnity  payment made by the Lessee,  then such Indemnitee shall pay
          to the Lessee the amount of such Tax savings  (together  with,  in the
          case of a refund, any interest received thereon) PROVIDED HOWEVER that


                                       35
<PAGE>

          such Indemnitee shall not be obliged to make any payment to the Lessee
          pursuant to this  sub-clause  (b) to the extent that the amount of any
          Tax savings in respect of which such payment is to be made (other than
          any portion thereof comprising  interest on a refund) would exceed the
          aggregate  amount  of all prior  payments  made by the  Lessee  to, on
          behalf  of, or as  indemnification  of,  such  Indemnitee  under  this
          Agreement  for  Taxes  less the  amount  of all  prior  payments  made
          pursuant  to this  sub-clause  (b) in respect of such Tax  savings and
          PROVIDED  FURTHER that should any Tax savings with respect to which an
          Indemnitee   shall  have  made  a  payment   under  this   Clause  5.7
          subsequently  be disallowed or reduced,  the Lessee shall,  on demand,
          refund such amount together with interest at LIBOR from the date which
          is the  later of the date of  disallowance  or the  date  payment  was
          demanded.  Such  Indemnitee  shall have the right to  arrange  its Tax
          affairs in whatever manner it sees fit;  provided that each Indemnitee
          shall act in good faith to claim any  refund,  deduction  or credit to
          which it is entitled and which,  if allowed by the  applicable  taxing
          authority,  would result in a required payment from such Indemnitee to
          the  Lessee  or a  reduction  in  the  amount  of a  payment  to  such
          Indemnitee from the Lessee under this Clause 5 and would not adversely
          affect such Indemnitee. Except to the extent provided in Clause 5.9 or
          Clause  5.16,  the  Lessee  shall  not have the right to  require  any
          Indemnitee to disclose its Tax filing information.

      (c) The Lessee shall hold each  Indemnitee  harmless on an After Tax Basis
          for any  Taxes  that  result  in whole or in part from any acts of the
          Lessee or a permitted user under Clauses 8.15 and 8.16.

      (d) The  Provisions of this Clause 5.7 and Clauses 5.8, 5.9,  5.10,  5.12,
          5.16,  8.15 and 8.16 shall survive the  termination  of this Agreement
          and the related operative documents,  and shall continue in full force
          and effect beyond the Expiry Date.

5.8   VALUE ADDED TAX

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

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

          (ii)"SUPPLY" includes anything on which VAT is chargeable.

      (b) The Lessee  will pay to the Lessor or the Trust  Company,  as the case
          may be, the amount of any VAT  chargeable in respect of any supply for
          VAT purposes under this Agreement.

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

                                       36

5.9   INFORMATION  If the  Lessee is  required  by any  applicable  law,  by the
      Lessor,  the Trust Company or the Beneficial  Owner or by any third party,
      to deliver any report or return in connection  with any Taxes,  the Lessee
      will duly  complete the same and, in  particular,  will not state or imply
      therein  that the Lessee is not  exclusively  responsible  for the use and
      operation  of the  Aircraft  and for the Taxes  (other than Lessor  Taxes)
      arising  therefrom  or take any  position  inconsistent  with the Lessor's
      status as the owner of the  Aircraft for the United  States tax  purposes,
      and the Lessee will, on reasonable request, supply a copy of the report or
      return to the Lessor,  the Trust Company or the Beneficial  Owner,  as the
      case may be. The Lessor,  the Trust Company and the Beneficial Owner shall
      provide to the Lessee such information  within their possession or control
      as is  reasonably  requested  by the Lessee and  necessary  for the proper
      completion  of any such report or return and the Lessee  shall  (except to
      the extent  incorporated  in such report or return,  or  necessary  to the
      verification  process described in Clause 5.16 or otherwise as the Lessor,
      the Trust  Company  or the  Beneficial  Owner,  as the case may be,  shall
      expressly  permit in writing after the Lessee's  request  setting forth in
      detail  the  reasons  disclosure  is  otherwise  necessary)  keep all such
      information strictly confidential.

5.10  TAXATION OF INDEMNITY PAYMENTS

      (a) If and to the extent  that any sums  payable to an  Indemnitee  by the
          Lessee under this Agreement by way of indemnity are  insufficient,  by
          reason  of any  Taxes  payable  in  respect  of  those  sums,  for the
          Indemnitee  to discharge the  corresponding  liability to the relevant
          third party  (including any taxation  authority),  or to reimburse the
          Indemnitee for the cost incurred by it to a third party (including any
          taxation  authority),  in each case after  taking into account any Tax
          benefits actually  realized by the Indemnitee  (whether in the form of
          credits,   deductions   or  otherwise)  as  a  result  of  the  matter
          indemnified against, the Lessee will pay to the Indemnitee such sum as
          will,  after the tax  liability  has been fully  satisfied,  leave the
          Indemnitee  with the same  amount as it would  have been  entitled  to
          receive in the absence of that  liability,  together  with interest on
          the amount of the deficit at the Default Rate in respect of the period
          commencing on the date on which the payment of taxation is due (or, if
          later,  the date the Lessee receives notice from the Indemnitee of the
          amount of such deficit) until payment by the Lessee.

      (b) If  and  to  the  extent  that  any  sums  constituting  (directly  or
          indirectly)  an indemnity to an  Indemnitee  but paid by the Lessee to
          any person  other than the  Indemnitee  are  treated as taxable in the
          hands of the  Indemnitee,  the Lessee will pay to the Indemnitee  such
          sum as will, after the tax liability  (computed by taking into account
          any Tax benefits actually  realised by the Indemnitee  (whether in the
          form of credits,  deductions  or otherwise) as a result of the payment
          to  such  other  person)  has  been  fully  satisfied,  indemnify  the
          Indemnitee to the same extent as it would have been indemnified in the


                                       37
<PAGE>

          absence  of such  liability,  together  with  interest  on the  amount
          payable  by the  Lessee  under  this  sub-clause  (b) at: (i) LIBOR in
          respect of the period  commencing  on the date on which the payment of
          taxation is due through and  including the date which is five (5) days
          after demand for such payment by the  Indemnitee  and (ii) the Default
          Rate thereafter until payment by the Lessee.

5.11  DEFAULT INTEREST

      If the Lessee or any Indemnitee  fails to pay the other any amount payable
      under this Agreement on the due date, such  non-performing  party will pay
      on demand from time to time to the party entitled to such payment interest
      (both before and after  judgment) on the amount,  from the due date to the
      day of payment  in full,  at the rate of one month  Dollar  LIBOR plus 300
      basis points (the "DEFAULT RATE").

      All such interest will be compounded  monthly and  calculated on the basis
      of the actual number of days elapsed and on a 365 day year.

5.12  CONTEST

      If a claim is made  against  any  Indemnitee  for any  Taxes for which the
      Indemnitee intends to seek indemnification hereunder, the Indemnitee shall
      promptly  notify the  Lessee.  If  requested  by the Lessee in writing and
      provided that no Event of Default is then continuing, the Indemnitee shall
      at the expense of the Lessee  (including  without  limitation,  all costs,
      expenses,  losses, legal and accounting fees and disbursements incurred by
      the Indemnitee reasonably allocable to such contest) in good faith contest
      or, at the Lessee's  request,  if permitted by applicable  law, permit the
      Lessee to contest (and in such case, provide all reasonable cooperation to
      the Lessee)  the  validity,  applicability  or amount of such Taxes by (A)
      resisting  payment  thereof  if  practicable,  (B)  paying  the same under
      protest,  if protest is necessary  and proper,  or (C) if payment be made,
      using  reasonable  efforts  to  obtain a refund  thereof,  in  appropriate
      administrative and judicial proceedings (including, without limitation, by
      pursuit of available  appeals if requested by the Lessee and if the Lessee
      provides the Indemnitee with an opinion of outside counsel (at the expense
      of the Lessee)  that such appeal has a realistic  possibility  of success;
      provided that no appeal shall be required to be taken to the United States
      Supreme  Court).  In any case in which the Indemnitee  shall  determine to
      pursue the contest by payment of the Tax, the Lessee shall advance,  on an
      interest  free basis and at no net after tax cost to the  Indemnitee,  the
      amount of the Tax and any interest, penalties or additions to Tax required
      to be paid as a precondition to such contest. The Indemnitee shall consult
      with the Lessee in good faith  regarding  the  manner of  contesting  such
      claim and shall keep the Lessee reasonably informed regarding the progress
      of such contest and shall not release,  settle,  compromise or abandon the
      contest of the Tax without the consent of the Lessee,  such consent not to


                                       38
<PAGE>

      be  unreasonably  withheld or delayed.  If the  Indemnitee  shall obtain a
      refund of or be entitled to a credit  against  other  liability for all or
      any part of such Taxes paid by the Lessee,  the  Indemnitee  shall pay the
      Lessee the amount of such  refund  attributable  to such Taxes paid by the
      Lessee,  after  deducting any costs and expenses that were incurred by the
      Indemnitee in connection therewith; provided that such amount shall not be
      payable  before such time as the Lessee  shall have made all  payments and
      indemnities then due to the Indemnitee  hereunder.  If in addition to such
      refund the Indemnitee shall receive an amount representing interest on the
      amount of such refund,  the Lessee shall be paid that  proportion  of such
      interest which is fairly attributable to Taxes paid by the Lessee prior to
      the receipt of such  refund;  provided,  however,  that no amount shall be
      payable under this or the preceding sentence during any period in which an
      Event  of  Default  has  occurred  and is  continuing.  If the  Indemnitee
      receives an award of attorneys' fees in a contest for which the Lessee has
      paid an allocable  portion of the contest  expenses,  the Indemnitee shall
      pay to the Lessee the same  proportion  of the amount of such award as the
      amount of  attorneys'  fees paid or  reimbursed by the Lessee bears to the
      total amount of the attorneys' fees actually incurred by the Indemnitee in
      conducting such contest.

      Notwithstanding  the  foregoing,  neither the Lessor nor the Trust Company
      shall be  required  to contest a Tax if the  action to be taken  creates a
      material  danger of sale,  forfeiture,  loss or  creation of a lien on the
      Aircraft,  the Airframe,  any Engine or any Part or on the Lessor (or Head
      Lessee's)  interest  therein,  and shall not be  obligated to continue the
      contest  of any Tax if (i) the  Lessee  has  failed to pay,  as and to the
      extent provided above, the expenses of such contest incurred by the Lessor
      or (ii) an Event of Default has  occurred and is then  continuing,  unless
      such  contest is being  conducted  as a claim for refund or the Lessee has
      provided  security for the  contested Tax  liability  satisfactory  to the
      Lessor or the Trust Company, as the case may be.

      Notwithstanding  the  foregoing,  neither the Lessor nor the Trust Company
      will be  required  to  contest  the  imposition  of any Taxes and shall be
      permitted to settle or compromise  any claim without the Lessee's  consent
      if the Lessor or the Trust  Company,  as the case may be, (i) shall  waive
      its right to indemnity  under  Clauses 5.6, 5.7, 5.10 and 8.4 with respect
      to such Taxes (and any directly related claim and any claim the outcome of
      which is  determined  based upon the outcome of such claim) and (ii) shall
      pay to the Lessee any amount  previously  paid or  advanced  by the Lessee
      pursuant to this Clause 5.12 with  respect to such Tax other than,  in the
      case of a contest  conducted by means of payment of the Tax, the amount of
      the Tax.

5.13  ABSOLUTE

      The Lessee's  obligations under this Agreement,  including its obligations
      to pay Rent and Agreed Value, are, subject to the Lessor's compliance with
      its covenant of quiet  enjoyment as  specifically  set forth in Clause 7.1
      hereof and the Beneficial  Owner's compliance with its undertakings as set
      forth in the letter of Quiet Enjoyment  delivered to the Lessee,  absolute
      and unconditional  irrespective of any contingency whatever including (but
      not limited to):

                                       39
<PAGE>

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

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

      (c) any lack or invalidity of title or any other defect in title (provided
          always that such lack or  invalidity of title or other defect does not
          result  in  the  Lessee  being  deprived  of  its  possession  of  the
          Aircraft),  airworthiness,  merchantability,  fitness for any purpose,
          condition,  design, or operation of any kind or nature of the Aircraft
          for any particular use or trade, or for  registration or documentation
          under the laws of any  relevant  jurisdiction,  or any  Total  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
          the Lessor or the Lessee;

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

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

      PROVIDED  ALWAYS that this Clause 5.13 shall be without  prejudice  to the
      Lessee's right to claim damages and/or other relief from the courts in the
      event of any breach by the Lessor of its obligations under this Agreement,
      or in the event that,  as a result of any lack or  invalidity  of title to
      the  Aircraft  on the part of the  Holder of Legal  Title,  the  Lessee is
      deprived of its possession of the Aircraft.

5.14  LESSOR'S MONEYS

      (a) It is intended by the Lessor and the Lessee  that the  Commitment  Fee
          payable  by the Lessee to the  Lessor  pursuant  to Clause 5.1 and the
          Supplemental  Rent are  amounts  paid by the  Lessee to the  Lessor in
          consideration  for the Lessor  removing the Aircraft  from the market,
          the use of the  Aircraft  by the  Lessee and the  satisfaction  of the
          Lessor's  obligations  under this Agreement and that, once paid, those
          moneys,  as well as any  interest  earned  thereon  or other  proceeds
          thereof,  irrevocably and unconditionally shall be the property of the
          Lessor,  and the Lessor may  commingle  with its other funds all funds
          paid by the Lessee under  Clause 5.1 and this Clause.  Notwithstanding
          that stated intent, if and to the extent that those moneys or any part
          thereof,  under any applicable law or otherwise,  are determined to be


                                       40
<PAGE>

          security  deposits or otherwise the property of the Lessee or if it is
          so  determined  those moneys are a debt owed to the Lessee or that the
          Lessee  shall  have  any  interest  in  those  moneys  (the  "LESSOR'S
          MONEYS"),  the parties agree that  subclauses  (b) and (c) below shall
          apply.

      (b) To  the  fullest  extent  permitted  by law  and by way of  continuing
          security  the Lessee  charges  and grants a security  interest  in the
          Lessor's Moneys and all rights of the Lessee to payment  thereof,  the
          debt  represented  thereby and all interest thereon and/or any and all
          interest of the Lessee  therein to the Lessor by way of first priority
          security  interest and first fixed charge as security for the Lessee's
          obligations   and  liability   under  this  Agreement  (the  "LESSEE'S
          LIABILITIES"). Except as expressly permitted under this Agreement, the
          Lessee  will not be entitled to payment of the  Lessor's  Moneys.  The
          Lessee will not assign,  transfer or otherwise  dispose of all or part
          of its rights or interest in the Lessor's Moneys and the Lessee agrees
          that it will  enter  into any  additional  documents  and  instruments
          necessary or  reasonably  requested  by Lessor to evidence,  create or
          perfect the Lessor's rights to the Lessor's Moneys.

      (c) If a  Significant  Default or an Event of Default has  occurred and is
          continuing the Lessor may  immediately or at any time  thereafter,  so
          long as such  Significant  Default or Event of Default is  continuing,
          without prior notice to the Lessee:

          (i) set-off all or any part of the Lessee's  Liabilities  then due and
              owing  against  the  liabilities  of the  Lessor in respect of the
              Lessor's Moneys; or

          (ii)apply or appropriate the Lessor's Moneys in or towards the payment
              or  discharge of the  Lessee's  Liabilities  then due and owing in
              such order as the Lessor sees fit.

5.15  LETTER OF CREDIT

      (a) If an Event of  Default  occurs and for as long as it  continues,  the
          Lessor may (but shall not be obliged  to) call on the Letter of Credit
          and use or apply the proceeds in or towards  satisfaction  of any sums
          due and payable to the Lessor under this  Agreement  or to  compensate
          the Lessor for any sums  which it  advances  or expends as a result of
          any such Event of Default. Notwithstanding any such use or application
          by the Lessor, the Lessee shall remain in default under this Agreement
          until the full amount owed by the Lessee,  including  interest accrued
          thereon  pursuant to Clause 5.11,  shall have been paid to the Lessor,
          subject  to the  conditions  set  forth in the  immediately  following
          paragraph,  as a cash  portion  of the  Commitment  Fee or the  Lessee
          procures the issue of a new Letter of Credit  acceptable to the Lessor
          for an amount  equal to the amount so used or applied  and pays to the
          Lessor an amount  equal to the  excess,  if any,  of (i) the amount so
          advanced  or  expended by the Lessor  plus  interest  accrued  thereon


                                       41
<PAGE>

          pursuant  to Clause  5.11 over (ii) the amount of the Letter of Credit
          proceeds drawn by the Lessor and so used or applied.

          Notwithstanding the foregoing, if, and to the extent that, the form of
          a new  Letter  of  Credit  procured  or  proposed  by  the  Lessee  in
          accordance  with this Agreement  (using its best efforts and acting in
          good  faith  to  procure  a new  Letter  of  Credit  to  the  Lessor's
          satisfaction),  is deemed  unsatisfactory  by the  Lessor,  the Lessee
          shall  have the right to pay the  equivalent  amount to the  Lessor in
          cash as a cash portion of the Commitment Fee.

      (b) The Letter of Credit  applicable  at the Expiry  Date shall not expire
          until 45 days after the scheduled Expiry Date.

      (c) The  Letter  of  Credit  shall be  returned  to the  Lessee  within 20
          Business Days of:

          (i) redelivery of the Aircraft to the Lessor in the condition required
              by Clause 12 of, and Schedule 3 to, this Agreement; or

          (ii)receipt by the Lessor of the Agreed Value following  a Total  Loss
              and all other amounts due under Clause 11.1(b); or

          in either  case,  at such  later  time that the Lessee has paid to the
          Lessor all amounts which are then outstanding or will be payable under
          this  Agreement,  PROVIDED ALWAYS that the Lessor shall not be obliged
          to return the Letter of Credit if and for so long as, at the  relevant
          time, an Event of Default shall have occurred and be continuing  under
          Clause 13.1(g) or (h).

5.16  VERIFICATION

      At the Lessee's request,  the computation of any amount owed by the Lessee
      or any amount owed to the Lessee  pursuant to Clause 5 or Clause 10 hereof
      shall be verified and certified by an independent  public  accounting firm
      selected by the Lessor and  reasonably  satisfactory  to the Lessee (which
      shall be a firm other than one typically employed by the Lessor respecting
      its tax matters and other than the firm originally preparing or previously
      reviewing the  computation  subject to  verification).  Such  verification
      shall be binding on both the Lessee and the Lessor absent  manifest error.
      The  costs  of  such  verification  (including  the  fee  of  such  public
      accounting  firm) shall be borne by the Lessee  unless  such  verification
      shall result in an adjustment in the Lessee's  favor of the greater of (i)
      5% or more of the payment as computed by the Lessor, and (ii) the costs of
      such verification in which case the costs shall be paid by the Lessor. The
      Lessor and the Lessee  shall  provide to such public  accounting  firm all
      information within its possession or control that is reasonably  necessary
      for  such  verification  and such  firm  shall  keep all such  information


                                       42
<PAGE>

      strictly  confidential,  and shall not  provide  either  the Lessor or the
      Lessee  access to any  information  provided by the other to such firm for
      purposes of such verification.

6.    MANUFACTURER'S WARRANTIES

6.1   ASSIGNMENT

      Notwithstanding this Agreement,  except as provided in this Clause 6.1 and
      Clause  6.2,  the  Lessor  will  remain  entitled  to the  benefit of each
      warranty,  express or implied,  and any unexpired  customer and/or product
      support given or provided in respect of the  Aircraft,  any Engine or Part
      by any  manufacturer,  vendor,  maintenance  performer,  subcontractor  or
      supplier.  Unless a Significant  Default or an Event of Default shall have
      occurred and be  continuing,  the Lessor hereby  assigns to the Lessee and
      authorizes  the  Lessee to  exercise  such  rights as the  Lessor may have
      thereunder  and the  Lessee  agrees to  diligently  pursue,  to the extent
      deemed  commercially  reasonable,  any such claim which  arises at its own
      cost.  The Lessee will notify the Lessor  promptly upon becoming  aware of
      any such claim.  The Lessor will provide such  assistance to the Lessee in
      making a claim  under  any such  warranties  or  customer  and/or  product
      support as the Lessee may  reasonably  request,  and, if  requested by the
      Lessee and at the  Lessee's  expense,  will pursue a claim in its own name
      where  the   relevant   manufacturer,   vendor,   maintenance   performer,
      subcontractor or supplier has refused to acknowledge the Lessee's right to
      pursue that claim. Where the Lessee has exercised its option not to pursue
      a claim on the basis that it is not  commercially  reasonable,  the Lessee
      shall, at no out-of-pocket  expense to the Lessee,  provide the Lessor all
      information and technical support as reasonably requested by the Lessor in
      order for the Lessor to pursue such claim at its own expense.

6.2   PROCEEDS

      The  Lessee  covenants  and  agrees to apply any  proceeds  of any  claims
      assigned  to the  Lessee by the  Lessor  under  Clause  6.1 to remedy  the
      defect,  if any,  in the  Aircraft,  any Engine or any Part giving rise to
      such claim if and to the extent  that such  defect  has not  already  been
      remedied.  So long as no  Significant  Default  or  Event of  Default  has
      occurred and is  continuing  and this  Agreement has not  terminated,  the
      Lessor agrees to cooperate  with the Lessee to cause any proceeds from any
      rights  assigned by the Lessor to the Lessee  under  Clause 6.1 to be paid
      directly to the Lessee,  and, if any such proceeds are nonetheless paid to
      the  Lessor,  the Lessor  agrees to remit  promptly  such  proceeds to the
      Lessee. However, upon the occurrence of an Event of Default or termination
      of this Agreement, whichever occurs earlier, the Lessor may immediately:

      (a) retain any such  proceeds  previously  paid to the Lessor  which would
          have been  remitted  to the Lessee  under this  Clause 6.2 absent such
          Event of Default; and

                                       43
<PAGE>

      (b) seek to cause any  proceeds  of any  pending  claims to be paid to the
          Lessor, rather than to the Lessee; and

      (c) seek  recovery  from  the  Lessee  the  proceeds  of any  such  claims
          previously paid to the Lessee to the extent that such claims relate to
          any  defect  in the  Aircraft,  any  Engine  or any part not fully and
          completely  rectified  by the Lessee  before  such Event of Default or
          termination.

      Provided,  however,  that if payment of any such proceeds to the Lessee is
      withheld due to one or more Events of Default, such proceeds shall be paid
      or remitted to the Lessee after all Events of Default are cured.

6.3   PARTS
      Except to the extent the Lessor otherwise agrees in a particular case, the
      Lessee will procure that all engines, components, furnishings or equipment
      provided by the manufacturer, vendor, maintenance performer, subcontractor
      or supplier as a  replacement  for a defective  Engine or Part pursuant to
      the terms of any warranty or customer and/or product  support  arrangement
      comply with Clause  8.13(a),  are  installed on the Aircraft  promptly and
      that title thereto  vests in the Holder of Legal Title in accordance  with
      Clause 8.17(a). On installation those items will be deemed to be an Engine
      or Part, as applicable.

6.4   AGREEMENT

      To the extent any warranties or customer and/or product  support  relating
      to the  Aircraft  are  made  available  under  an  agreement  between  any
      manufacturer, vendor, maintenance performer, subcontractor or supplier and
      the Lessee, this Clause 6 is subject to that agreement.
      However the Lessee will:

      (a) pay the proceeds of any claim  thereunder  to the Lessor to the extent
          such  proceeds  would not be payable to the Lessee  pursuant to Clause
          6.2 and, pending such payment, will hold the claim and the proceeds on
          trust for the Lessor; and

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

7.    LESSOR'S COVENANTS AND DISCLAIMERS

7.1   QUIET ENJOYMENT

      The  Lessor  covenants  that  neither  the Lessor nor any person or entity
      lawfully  claiming by or through the Lessor will  interfere with the quiet
      use,  possession  and  enjoyment  of the  Aircraft  by the  Lessee  or the
      exercise by the Lessee in  accordance  with this  Agreement  of its rights


                                       44
<PAGE>

      with respect to the Aircraft and all rents,  revenues,  profits and income
      therefrom;  provided,  however,  that the  exercise  by the  Lessor of its
      rights in  accordance  with this  Agreement  will not  constitute  such an
      interference.

7.2   MAINTENANCE CONTRIBUTION

      Provided no  Significant  Default or Event of Default has  occurred and is
      continuing (but in such case, at such time as such Significant  Default or
      Event of Default  is no longer  continuing),  the  Lessor  will pay to the
      Lessee, by way of contribution to the cost of maintenance of the Aircraft,
      within 14 days after  submission by the Lessee to the Lessor of an invoice
      and  supporting   documentation  reasonably  satisfactory  to  the  Lessor
      evidencing:

      (a) with respect to the Airframe, the completion,  in accordance with this
          Agreement,  of  those  items  of  maintenance   characterized  by  the
          manufacturer's  maintenance  planning  document  as  "Structural  C-7"
          Check, as defined by the Agreed Maintenance Programme, (or equivalent)
          (but not including  repairs  arising as the result of  operational  or
          maintenance  mishandling or accidental damage),  the lesser of (i) the
          amount  of that  invoice  and (ii) an  amount  equal to the  aggregate
          amount of Airframe  Supplemental Rent paid under this Agreement,  LESS
          the  aggregate  amount  previously  paid  by  the  Lessor  under  this
          sub-clause (a);

      (b) with respect to any Engine,  the performance,  in accordance with this
          Agreement,  of all shop visits  requiring an off-wing  teardown and/or
          disassembly  and resulting in the  refurbishment  and  restoration  of
          operating  performance  and/or the  replacement of Engine LLP's (other
          than (aa) the  repairs of foreign  object  damage or damage  resulting
          from operational or from maintenance  mishandling except to the extent
          such  overhaul  or  replacement   results  in  the   refurbishment  or
          "betterment"   of  the  Engine  and/or  (bb)  removal,   installation,
          maintenance and repair of QEC (Quick Engine Change) kits),  the lesser
          of (i) the  amount of that  invoice  and (ii) an  amount  equal to the

          Engine under this Agreement, LESS the aggregate amount previously paid
          in respect of that Engine by the Lessor under this sub-clause (b); and

      (c) with respect to any Engine LLP's, the performance,  in accordance with
          this Agreement,  of all work on such Engine LLP's,  including overhaul
          or  replacement  (other than overhaul or replacement of foreign object
          damage or operational or maintenance  mishandling except to the extent
          such  overhaul  or  replacement   results  in  the   refurbishment  or
          "betterment"  of the  Engine),  the  lesser of (i) the  amount of that
          invoice and (ii) an amount equal to the aggregate amount of Engine LLP

          Engine),  LESS the aggregate amount  previously paid in respect of the

          such Engine under this sub-clause (c);

      (d) with respect to the Landing Gear, the  performance in accordance  with
          this  Agreement,  of all work on the  Landing  Gear in the  nature  of
          overhaul and requiring removal and disassembly  (other than the repair
          of  damage  arising  as  the  result  of  operational  or  maintenance
          mishandling or accident), the lesser of (i) the amount of that invoice
          and (ii) an  amount  equal to the  aggregate  amount of  Landing  Gear
          Supplemental Rent paid under this Agreement, LESS the aggregate amount
          previously paid by the Lessor under this sub-clause (d); and

          terms as set forth in Letter Agreement No. 1.

      Notwithstanding  the above provisions of this Clause 7.2, the Lessee shall
      not be entitled to receive any such  contributions  in respect of the cost

7.3   THE LESSOR'S OBLIGATIONS FOLLOWING EXPIRY DATE

      So long as no Significant  Default or Event of Default has occurred and is
      continuing, within 3 Business Days of:

      (a) redelivery of the  Aircraft to  the  Lessor in  accordance with and in
          the condition required by this Agreement; or

      (b) payment to the Lessor of the Agreed Value following a Total Loss after
          Delivery,

      the Lessor will pay to the Lessee:

          (i) by way of (A) rebate of the  Commitment Fee that is in the form of
              cash,  an amount equal to the sums paid by the Lessee  pursuant to
              Clause 5.1 (and not  otherwise  applied by the Lessor  pursuant to
              Clause 5.14(c) plus interest  accrued  thereon  pursuant to Clause
              5.1) or (B) if the  Commitment  Fee is in the form of a Letter  of
              Credit,  returning the Letter of Credit,  net of any amounts drawn
              pursuant to Clause 5.14(c);

          (ii)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

                                       46
<PAGE>

          (iii) in the case of a Total Loss only, by way of further contribution
              to the cost of maintenance of the Aircraft, an amount equal to the
              amount by which the aggregate amount of Supplemental  Rent paid by
              the Lessee  exceeds the aggregate  amount paid by the Lessor under
              Clause 7.2 (other than paragraph (e) thereof).

      (c) anything in this  Agreement  to the contrary  notwithstanding,  in the
          event that any amount  otherwise  payable to the Lessee is retained by
          the Lessor as the result of the occurrence of a Significant Default or
          an Event of Default hereunder, the Lessor shall pay such amount to the
          Lessee at such time as such Significant Default or Event of Default is
          no longer continuing and, in the event that the Significant Default or
          the Event of Default  giving rise to the Lessor's right to retain such
          amount  constitutes  a default  in the  payment  of money  owed by the
          Lessee to the  Lessor  and the  aggregate  amount so  retained  by the
          Lessor (the "Retained  Amount")  equals or exceeds the amount which is
          the subject of such payment default (the "Default Amount"), the Lessor
          shall deduct from the  Retained  Amount an amount equal to the Default
          Amount (and such deduction shall  constitute  payment by the Lessee of
          the  payment  obligations  which  is the  subject  of the  Significant
          Default or the Event of Default)  and shall pay over to the Lessee the
          amount, if any, equal to the balance of the Retained Amount.

      AND  DELIVERED  HEREUNDER  "AS IS,  WHERE IS" AND THE  LESSEE  AGREES  AND

      appropriate  proceedings,  in respect of which adequate reserves have been
      established by the Lessee in accordance with GAAP and non-payment of which
      does not give  rise to the  likelihood  of the  Aircraft  or any  interest
      therein being seized,  condemned,  sold, forfeited or otherwise lost or of
      criminal  liability  or  unindemnified   liability  on  the  part  of  any

           with possession:

           (i)  with  respect to the  Aircraft,  the  Engines or any Part to the

           (ii) the  proposed  sub-lessee  (the  "PERMITTED  SUB-LESSEE")  is  a
                reputable,  duly licensed and certificated  operator of aircraft

                resident in one of the jurisdictions specified in Schedule 10;

           (iii)the terms of the proposed sub-lease (the "PERMITTED  Sub-Lease")
                shall,  when taken together with this Agreement,  allow for full
                compliance with the Lessee's obligations hereunder;

           (iv) during the term of the  Permitted  Sub-Lease,  the Lessee  shall
                remain   primarily   liable  for  the  performance  of  all  its
                obligations under this Agreement;

           (v)  the term of the  Permitted  Sub-Lease  shall not  extend,  or be
                capable of being extended, beyond the scheduled Expiry Date;

                subordinate  to this  Agreement  and the  rights  of the  Lessor
                hereunder;

           (vii)the  Permitted  Sub-Lease  shall  not  be  amended  without  the
                Lessor's   prior  written   consent  (such  consent  not  to  be
                unreasonably withheld);

                                       53
<PAGE>

           (viii) prior to delivery of the Aircraft to the Permitted Sub-Lessee,
                the Lessee  shall  execute  and deliver to the Lessor a security
                assignment of the benefit of the Permitted Sub-Lease in form and
                substance  reasonably  satisfactory to the Lessor, shall deliver
                notice of such assignment to the Permitted Sub-Lessee, and shall
                procure that the Permitted  Sub-Lessee  acknowledges such notice
                to the Lessor  (which  such  acknowledgment  shall  contain  the
                Permitted  Sub-Lessee's  confirmation  of the matters set out in
                sub-clauses (vi) and (vii) above). Any such security  assignment
                shall  provide  that the  Lessee  as the  sub-lessor  under  the

                rentals  paid by the  Permitted  Sub-Lessee  unless and until an
                Event of Default  occurs under this  Agreement;  provided  that,
                during the continuation of an Event of Default, the Lessor shall
                have the right,  but not the obligation,  to receive the rentals
                paid by the  Permitted  Sub-Lessee  and to  apply  such  rentals
                toward the  obligations  of the Lessee then due  hereunder;  and
                provided  further that at such time as no Event of Default shall
                be continuing hereunder, the Lessor shall pay over to the Lessee
                that portion of such  rentals  received by the Lessor and not so
                applied by the Lessor toward such obligations of the Lessee.

           (ix) in the event that,  pursuant  to the  Permitted  Sub-Lease,  the
                Aircraft  is to be  de-registered  from  the  national  aircraft
                register in the State of Registration,  the Permitted Sub-Lessee
                shall have  provided  the Lessor and the Lessee with a valid and
                irrevocable power of attorney  authorizing the Lessor and/or the
                Lessee to  de-register  the Aircraft from the national  aircraft
                register  of the new  State of  registration  in the  event of a
                termination  of the Permitted  Sub-Lease as a  consequence  of a
                default on the part of the Permitted Sub-Lessee;

           (x)  the  Lessor  shall  have  received  a legal  opinion  reasonably
                satisfactory  to it in all respects from a reputable  counsel in
                the   jurisdiction   in  which  the   Permitted   Sub-Lessee  is

           of such inspection.

      (b)  The Lessor shall bear its own costs and expenses in  connection  with
           any such visit,  inspection or survey unless the visit, inspection or

           cm. x 7 cm.) in a reasonably  prominent  position on the Aircraft and
           on each Engine stating:

           "This  Aircraft/Engine is leased by Wilmington Trust Company,  not in
           its individual  capacity but solely as Owner Trustee (for the benefit
           of Sunrock Aircraft  Corporation  Limited),  as Lessor,  which is the

           Co., Ltd.";

      (e)  not  create  or  permit  to  exist  any  Security  Interest  upon the
           Aircraft, any Engine or any Part;

      (f)  not  do or  permit  to be done  anything  which   may  reasonably  be
           expected  to   expose  the   Aircraft,  any  Engine  or any  Part  to
           penalty,  forfeiture, impounding,  detention,  appropriation,  damage
           or  destruction  and,  without  prejudice  to the  foregoing,  if any
           such penalty,  forfeiture,  impounding,  detention  or appropriation,
           damage  or destruction  occurs,  give the  Lessor notice and use best
           endeavors to  procure the  immediate   release of the  Aircraft,  any
           Engine or the Part, as the case may be;

      (g)  not during the  Term  abandon  the  Aircraft, the Engine or any Part;

      (h)  pay and  discharge or  cause to be paid and  discharged  when due and

           rise  to a Security  Interest over  or affecting  the  Aircraft,  any
           Engine or any  Part except to the  extent  that such debts,  damages,
           claims and  liabilities,  in respect of which  adequate reserves have
           been  established  by the Lessee in accordance  with  GAAP, are being
           contested in good  faith by appropriate  proceedings  and  nonpayment
           of which  does not  give rise to the  likelihood  of the  Aircraft or
           any interest  therein being  seized,  condemned,  sold,  forfeited or
           otherwise lost or of  criminal liability or  unindemnified  liability
           on the part of any Indemnitee; and

      (i)  not attempt,  or hold itself out as having any power, to sell,  lease

           Colorado Springs, CO 80906, to another state;

      (d)  remain a  certificated  air carrier and  maintain its status so as to

8.10  REGISTRATION AND FILINGS

      The Lessee shall:

      (a)  maintain the registration of the Aircraft with the Aviation Authority
           reflecting  (so far as permitted by  applicable  law) the interest of

           other  Government  Entity) and executing and delivering all documents
           (including,  without limitation,  any amendment of this Agreement) as
           may be reasonably requested by the Lessor:

           (i)  at the Lessor's expense  following any change or proposed change

           (iii)to establish, maintain, preserve, perfect and protect the rights
                in the Aircraft of the Lessor under this Agreement and the Banks
                or other  assignees  in the  Assignment,  provided  that no such
                action need be taken by the Lessee pursuant to this provision if
                such action would adversely affect any of its material rights or
                privileges or materially increase its obligations or liabilities
                hereunder,  and shall not  knowingly  take any action that would
                prejudice  the rights of the Head Lessor in the  Aircraft  under

<PAGE>

      (d)  maintain  the  Aircraft  in  accordance  with FAR Part 121 and/or any
           other  applicable  rules and  regulations  of the FAA,  except to the

           Aviation Authority;

      (e)  comply with all mandatory  inspection and modification  requirements,
           airworthiness  directives and similar requirements  applicable to the

           service  bulletin  with  respect to  substantially  all of the Boeing
           737-300  aircraft  in its  fleet and has  commenced  such  compliance
           with  respect  to  other such  aircraft and (ii) after the Lessee has
           reached  such  decision  and  before  the Expiry  Date,  the Aircraft

           fleet generally which are of the same type as the Engines; and

                                       59
<PAGE>

      (k)  subject to Clause  11.1(c),  procure promptly  the replacement of any

8.12  REMOVAL OF ENGINES AND PARTS

      The Lessee will ensure that no Engine or Part installed on the Aircraft is
      at any time removed from the Aircraft other than:

      (a)  if replaced as permitted by and in accordance  with this Agreement;
           or

      (b)  if the removal is of an obsolete item and is in  accordance  with the

      (c)  pursuant to, and in accordance with, Clause 8.15; or

      (d   (i)  during   the  course  of   maintaining,   servicing,  repairing,
                overhauling or testing that Engine or the Aircraft,  as the case
                may be; or

           (ii) as part of a normal engine or part rotation programme; or

           (iii)for the purpose of making such  modifications to the Engine or
                the Aircraft,  as the case may be, as are permitted under this
                Agreement,

           and then in each case only if it is  reinstalled  or  replaced  by an
           engine or part  complying  with Clause 8.13(a) as soon as practicable
           and in any event no later than the Expiry Date.

8.13  INSTALLATION OF ENGINES AND PARTS

      The Lessee will:

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

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

                                       60
<PAGE>

           (ii) in the case of a part, it is in as good operating condition,  is
                of the same or a more  advanced  make and model and has a value,
                utility and remaining  useful life,  and at least the equivalent
                or   better    modification    status   and   service   bulletin
                accomplishment status, as the replaced Part;

           (iii)in each case,  it has become and  remains  the  property  of the
                Holder  of Legal  Title  free  from  Security  Interests  and on
                installation  on the  Aircraft  will,  without  further  act, be
                subject to this Agreement; and

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

      (b)  if no  Significant  Default or  Event  of Default has occurred  which
           is  continuing,  be  entitled  to  install any  engine or part on the
           Aircraft  by  way of  replacement   notwithstanding   Clause  8.13(a)
           provided   that as  soon as  practicable  after  installation  of the
           same on  the  Aircraft  but, in any  event,  no later than the Expiry
           Date,  the Lessee  removes  any such  engine or part and  replaces it
           with the Engine or Part  replaced by  it or by an  engine or part, as
           the case may be, complying with Clause 8.13(a).

      Lessor agrees, and will at the request of Lessee acknowledge in writing to
      the owner of any installed engine, that it will recognize the interests of
      such  owner and any  lessor in the  installed  engine and will not seek to
      exercise any rights whatsoever in relation to it.

8.14  NON-INSTALLED ENGINES AND PARTS

      The Lessee will:

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

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

                                       61

      (c)  (notwithstanding   any  other  provision  in  this   Agreement),   be
           permitted, if no Significant Default or Event of Default has occurred
           and is continuing,  to install any Engine or Part on an aircraft,  or
           in the case of a Part, an engine:

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

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

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

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

           (1)  the  terms of any such  lease,  conditional  sale  agreement  or
                Security  Interest will not have the effect of  prejudicing  the
                title and  interest  of the Holder of Legal Title to and in that
                Engine or Part or the interests of the Banks in respect  thereof
                under the Assignment; and

           (2)  as provided in Section 8 of Letter  Agreement  No. 1, the lessor
                under  such  lease,  the  seller  under  such  conditional  sale
                agreement or the holder of such Security  Interest,  as the case
                may be,  has  confirmed  that  it will  respect  the  title  and
                interest  of the  Holder of Legal  Title and the Banks to and in
                that  Engine or Part and that it will not seek to  exercise  any
                rights whatever in relation thereto.

8.15  POOLING OF ENGINES AND PARTS

      The  Lessee  will not enter  into nor  permit  any  pooling  agreement  or
      arrangement  in respect  of an Engine or Part  without  the prior  written
      consent of the Lessor, such consent not to be unreasonably withheld in any
      case  where an Engine or Part is  leased,  let on hire or  otherwise  made
      available  by the Lessee.  So long as no  Significant  Default or Event of
      Default has occurred and is continuing,  the Lessee may lease, let or hire
      or charter or otherwise part with  possession of (i) any Engine so long as
      such Engine is transferred to such Engine's  manufacturer or (ii) Part (in
      the case of each clause (i) and (ii) above,  on terms  conferring  no more
      than a contractual right in personam against the Lessee and not a right in
      rem against such Part) pursuant to a pooling or interchange arrangement to
      which the Lessee is a party; and:

      (a)  (A) with respect to an Engine,  the other party to which is an Engine
           manufacturer and (B) with respect to Part, the other parties to which
           are reputable,  solvent  commercial air carriers or the manufacturers


                                       62
<PAGE>

           or suppliers of Part (or other reputable, solvent organizations whose
           business  includes the  administration  of and  participation in such
           pooling agreements or arrangements); and

      (b)  which does not contemplate the transfer of title to the pooled Engine
           or Part (or if title to the Engine is transferred, it will be treated
           as a Total Loss); and

      (c)  either  provides  that the Lessor (or the Banks,  as the case may be)
           will be sole  loss  payee in  respect  of any loss or  damage  to the
           Engine or Part,  or  provides  for  Holder of Legal  Title to acquire
           title to a substitute  engine or part  satisfying  the conditions set
           out in Clause 8.13(a) if the Engine or Part is destroyed.

8.16  EQUIPMENT   CHANGES;   NON-SEVERABLE   MODIFICATIONS   AND   SEVERABLE
      MODIFICATIONS

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

           (i)  is  permitted  by and in  accordance   with  this  Agreement  or
                required by the Aviation Authority, or

           (ii) has the prior written consent of the Lessor (which consent shall
                state  whether or not the  Equipment  Change needs to be removed
                and the  Aircraft  restored to the prior  condition on or before
                the Expiry Date).

      (b)  The Lessee will not, without the prior written consent of the Lessor,
           make any Non-Severable Modification to the Aircraft, such consent not
           to be  unreasonably  withheld  or  delayed.  Any  such  Non-Severable
           Modification  shall, upon  incorporation in the Aircraft,  become the
           property of the Holder of Legal Title.

      (c)  Notwithstanding  Clause  8.16(a) above,  the Lessee  may at any time,
           and from time to time,  without  the prior  consent of the Lessor, so
           long as  no  Significant  Default or Event of  Default  has  occurred
           and   is   continuing,   install   on  the  Aircraft  any   Severable
           Modification.   Title  to  any  such   Severable  Modification  shall
           remain  in  the  Lessee  and shall not be  conveyed  to the Lessor as
           the   result  of  its  installation  in  the  Aircraft.  Provided  no
           Significant  Default or Event  of Default shall  have occurred and be
           continuing,  the Lessee may  remove any such  Severable  Modification
           at any time,  provided  that, in connection  with  such removal,  the
           Lessee  restores  the  Aircraft in  to the  condition  it  would have
           been in had  the  installation  of such  Severable  Modification  not
           occurred.  Any  such  Severable  Modification  which  is not  removed
           from the  Aircraft  prior to  its  return  to  the  Lessor  hereunder
           shall,  subject to  such rights as  any third party may have,  become
           the property of the Holder of Legal Title.

                                       63
<PAGE>

      For the avoidance of doubt (i) no Equipment Change, whether in the form of
      Severable  Modification or  Non-Severable  Modification,  may diminish the
      value,  utility,  condition or  airworthiness of the Aircraft and (ii) any
      Severable  Modification  to which title is not vested in the Lessee  shall
      require the Lessor's consent, such consent not to be unreasonably withheld
      or delayed.

8.17  TITLE TO ENGINES AND PARTS

      (a)  Title to al   engines and  parts  installed on the Aircraft,  whether
           by way of  replacement,  as the result of an  Equipment Change (other
           than  Severable  Modification) or  otherwise  (except those installed
           pursuant  to Clauses 8.13(b),  8.14(c), 8.15 or 8.16 (in  relation to
           parts which are  leased to the  Lessee))  will on   installation,  be
           conveyed  to the  Holder of Legal  Title  subject  to this  Agreement
           free  and clear of  all  Security  Interests.  The Lessee will at its
           own  expense  take all  such  steps  and  execute,  and  procure  the
           execution  of, all  such  instruments  as the Lessor  or Head Lessor,
           as the case  may be,  may reasonably  request and which are necessary
           to ensure   that  title  to any such  Engine or Part so passes to the
           Holder  of Legal Title  according  to all   applicable  laws.  At any
           time when   requested by the Holder of  Legal Title,  the Lessee will
           provide,  at   the  Lessee's  expense,   evidence  to   the  Lessor's
           reasonable  satisfaction  (including the  provision, if  required, to
           the Lessor of  one of more legal  opinions)  that title has so passed
           to the Holder of Legal Title;

      (b)  The Lessor may  require  the  Lessee to remove any  Equipment  Change
           (other than  Non-Severable  Modification) and to restore the Aircraft
           to its condition prior to that Equipment Change, except as the Lessor
           expressly  stated  otherwise in its prior written consent pursuant to
           Clause 8.16(a)(ii);

      (c)  Except as  referred to  in Clause 8.16(b),  any Engine or Part at any
           time  removed  from  the  Aircraft  will  remain the  property of the
           Holder  of  Legal  Title  until  a  replacement   has   been  made in
           accordance with this  Agreement and until title to  that  replacement
           has passed,  according  to  applicable  laws, to  the Holder of Legal
           Title  subject to  this  Agreement  free of  all  Security  Interests
           whereupon  title  to   the   Engine  or  Part,   will,   provided  no
           Significant  Default  or   Event  of  Default   has  occurred  and is
           continuing,  pass to the  Lessee  free of Lessor  Liens and  in  such
           event the  Holder of  Legal  Title  will  provide,  at  the  Lessee's
           expense,  evidence to  the   Lessee's  reasonable  satisfaction  that
           title has so passed to the Lessee.

9.    INSURANCE

9.1   INSURANCES

      The Lessee, at its expense,  will maintain in full force and effect during
      the  Term,  and  thereafter  as  expressly  required  in  this  Agreement,


                                       64
<PAGE>

      insurances  in respect of the  Aircraft in form and  substance  reasonably
      satisfactory to the Lessor (the  "INSURANCES"  which expression  includes,
      where the context so admits,  any relevant  re-insurance(s))  through such
      brokers  and with such  insurers  and having  such  deductibles  and being
      subject to such exclusions as may be approved by the Lessor, such approval
      not to be unreasonably withheld, it being understood that (i) the Lessee's
      brokers and  insurers  will be deemed  satisfactory  to the Lessor if such
      brokers and  insurers  are of  recognized  responsibility  and good repute
      specializing  in  aviation  insurances  in the  World  Aviation  Insurance
      Markets (as defined  below) at the time and (ii) the Lessee's  insurances,
      including  deductibles  and  exclusions,  will be deemed  satisfactory  to
      Lessor if  consistent  with  insurances  maintained  with  respect  to air
      carriers of a similar  size as Lessee and  operating  similar  aircraft on
      similar routes as Lessee at the time of any such approval.  The Insurances
      will be effected either:

      (a)  on a direct basis with insurers of recognized  standing who regularly
           participate  in aviation  insurances  in the London,  United  States,
           European,  Japanese or other leading international  insurance markets
           and  led  by  reputable  underwriter(s)  ("World  Aviation  Insurance
           Markets"); or

      (b)  with  a  single   insurer  or  group  of   insurers  specializing  in
           aviation  insurances  in the  World Aviation Insurance Markets who do
           not  retain   the  risk  but  effect  substantial   reinsurance  with
           reinsurers  in  the World  Aviation  Insurance  Markets  and  through
           brokers    each   of   recognized    responsibility    and   standing
           specializing   in   aviation   insurances  in   the  World   Aviation
           Insurance  Markets  for  a  percentage  of  all  risks  insured  (the
           "Reinsurances").

9.2   REQUIREMENTS

      The  requirements  with regard to the  Insurances are as specified in this
      Clause and in Part 1 of Schedule 4. The Lessor  acting  reasonably  and in
      consultation  with  Lessee,  may from time to time  stipulate  such  other
      requirements  for the  Insurances  as may be  necessary to ensure that the
      scope  and  level of  cover  is  maintained  in  accordance  with the then
      prevailing  industry  practice in the World Aviation  Insurance Markets in
      relation  to  aircraft  of the same type as the  Aircraft  in  relation to
      United  States  airlines  of similar  standing  to the  Lessee;  provided,
      however, that any such further requirements shall be of the type generally
      available in such markets at commercially  reasonable rates. If the Lessor
      determines that the Agreed Value shall be adjusted in accordance with this
      Agreement,  the Lessor  may,  upon prior  written  notice to the Lessee at
      least 30 days prior to the expiry of the  respective  Insurances,  require
      the Lessee to renew the Insurances reflecting the Agreed Value so adjusted
      in accordance with this Agreement.

9.3   CHANGE

      If at any time, the Lessor decides,  on reasonable  grounds, to revoke its
      approval of any  insurer,  reinsurers,  Insurances  or  Reinsurances,  the


                                       65
<PAGE>

      Lessor  shall  notify the  Lessee  accordingly  and the Lessor  and/or its
      brokers  will then  consult in good faith with the Lessee and the Lessee's
      brokers (as for the time being approved by the Lessor) with regard to such
      proposed  revocation.  If,  following  the  consultation,  the  Lessor  is
      satisfied  that  changes  should be made,  the Lessee will then arrange or
      procure the arrangement of alternative  cover  reasonably  satisfactory to
      the Lessor. For purposes of this Clause 9.3,  "reasonable grounds" for the
      Lessor's  decision  hereunder  shall  include any similar  decision  under
      similar  conditions by the Head Lessor or the Security Trustee (as defined
      in the Head Lease) under Clause 13.11 of the Head Lease.

9.4   INSURANCE COVENANTS

      The Lessee shall:

      (a)  ensure that all legal  requirements  as to insurance of the Aircraft,
           any  Engine or any Part which may from time to time be imposed by the
           laws of the State of Registration or any state to, from or over which
           the  Aircraft  may be flown in so far as they  affect or concern  the
           operation  of the  Aircraft,  are complied  with and, in  particular,
           those requirements compliance with which is necessary to ensure that:

           (i)  the Aircraft is not in danger of detention or forfeiture;

           (ii) the Insurances remain valid and in full force and effect; and

           (iii)the interests of the  Indemnitees  in  the  Insurances  and  the
                Aircraft or any Part are not thereby prejudiced;

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

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

           (i)  invalidates   or  is  reasonably  expected   to  invalidate  the
                Insurances; or

           (ii) renders or is reasonably expected to render void or voidable the
                whole or any part of any of the Insurances; or

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

      (d)  not take  out  without the  prior  written  consent of the Lessor any
           insurance  or  reinsurance  in  respect  of the  Aircraft  other than


                                       66
<PAGE>

           those required under this Agreement,  if  such  other insurance would
           prejudice  the   Lessor's  or  any  other  Indemnitee's  rights  with
           respect to  the Insurances.  The Lessor  agrees that,  subject to the
           foregoing,  the  Lessee   may  maintain   additional  hull  or  other
           insurance in relation to  the Aircraft,  Engines or  Parts thereof or
           insurance  in  excess  of  the  amounts  required  to  be  maintained
           hereunder.  Insurance  proceeds  arising out  of such other or excess
           insurance shall be paid solely to the Lessee.

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

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

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

           (iii)certificates of insurance (and where appropriate certificates of
                reinsurance), and broker's (and any reinsurance brokers') letter
                of undertaking  substantially in the form set out in Parts 2 and
                3 of Schedule 4,  detailing  the  coverage  and  confirming  the
                insurers'  (and  any  reinsurers')  agreement  to the  specified
                insurance  requirements  of this  Agreement  within 7 days after
                each renewal date;

      (f)  on request  and  subject  to clause (j) below,  provide to the Lessor
           copies of documents evidencing the Insurances;

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

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

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

      (j)  provide any  other  insurance and  reinsurance  related  information,
           or  assistance,  in  respect  of  the   Insurances  as the Lessor may
           reasonably  request,  provided  always  that  the  provision  thereof
           would  not violate  any  confidentiality  undertaking  of the  Lessee
           with  such  insurers  and that  the Lessor  shall not  disclose  such
           information to any third  parties  other than the  Beneficial  Owner,
           the  Banks,  the  Head  Lessor  and  their  respective   professional
           advisors  or as  may be  required  by  applicable  law, in each  case
           obtaining such  undertakings  and  taking such  precautions  as shall
           be commercially  reasonable  under  the  circumstances to protect the
           confidentiality  of  such   information.  The  Lessee  shall  not  be
           required to provide  any actual  insurance  policy  hereunder  unless


                                       67
<PAGE>

           the insurers  decline  coverage  and a good  faith dispute  exists in
           respect  thereof  with  the Lessor  in which  event the Lessee  shall
           provide such  portions of  such policies  bearing on such coverage or
           dispute as the Lessor may reasonably request.

9.5   FAILURE TO INSURE

      If the Lessee  fails to  maintain  the  Insurances  in  compliance  in all
      material  respects with this Agreement,  each of the  Indemnitees  will be
      entitled  but not bound  (without  prejudice  to any  other  rights of the
      Lessor under this Agreement,  but after such  consultation with the Lessee
      as shall be reasonable under the circumstances):

      (a)  to pay  the   premiums  due or  to  effect  and  maintain  insurances
           satisfactory  to it or  otherwise   remedy  the  Lessee's  failure in
           such manner (including,  without  limitation,  to effect and maintain
           similar  insurance  cover through  an "owners'  interest"  policy) as
           it reasonably  considers  appropriate.  Such  sums as shall have been
           reasonably  so  expended  by it  will  upon   written  demand  become
           immediately  due and  payable  by  the Lessee to the Lessor  together
           with  interest  thereon   at  the  Default  Rate,  from  the  date of
           expenditure  by it up to  the  date of  reimbursement  by the  Lessee
           (before and after any judgment);

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

9.6   CONTINUING INDEMNITY

      The Lessor or the Trust  Company may  require the Lessee to effect  and/or
      maintain  public  liability  insurance  under the  Lessee's  normal  fleet
      policies  after the Expiry Date with  respect to its  liability  under the
      indemnities  in Clause 10 for such  period as the  Lessor  may  reasonably
      require (but in any event not more than 2 years)  which  provides for each
      Indemnitee  to be named as  additional  insured.  The Lessee's  obligation
      under this Clause 9.6 shall not be  affected  by the Lessee  ceasing to be
      lessee of the Aircraft and/or any of the  Indemnitees  ceasing to have any
      interest in respect of the Aircraft.

9.7   APPLICATION OF INSURANCE PROCEEDS

      As between the Lessor and the Lessee:

      (a)  all  insurance  payments  received  as the  result  of a  Total  Loss
           occurring  during  the Term will be paid to the  Lessor up to but not
           exceeding the Agreed Value;

      (b)  all  insurance  proceeds  in  respect  of any  damage  or loss to the
           Aircraft,  any  Engine or any  Part  occurring  during  the  Term not
           constituting  a  Total  Loss  and  equal or in  excess  of $[ ]* will


                                       68

           be paid to the  Lessor and applied  in payment (or to  reimburse  the
           Lessee) for repairs or replacement  property  upon the  repairs being
           made or replacement  being  effected to  the reasonable  satisfaction
           of  the  Lessor  in   accordance  with  this   Agreement.   Insurance
           proceeds  in  amounts   below  $[ ]* may  be  paid   by  the  insurer
           directly to  the Lessee.  Any balance  remaining  after completion of
           repairs and/or replacement may be retained by the Lessee;

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

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

10.   INDEMNITY

10.1  GENERAL

      The Lessee agrees to defend,  indemnify and hold harmless the  Indemnitees
      on an  After-Tax-Basis  from and against any and all claims,  proceedings,
      losses, liabilities, suits, judgments, costs, expenses, penalties or fines
      (each a "Claim"):

      (a)  which  may  at  any   time  be  suffered  or  incurred   directly  or
           indirectly  as  a  result  of  or  connected  with  the  manufacture,
           design,    airworthiness,    merchantability,    fitness   for   use,
           possession,    delivery,   performance,    management,     ownership,
           registration,    deregistration,  control,   maintenance,  condition,
           service,  repair,   overhaul,  import,  export, leasing,  subleasing,
           pooling,  use,  operation or  return of  the Aircraft,  any Engine or
           Part (either  in the air or on  the ground)  whether or not the Claim
           may be  attributable  to any  defect  in the Aircraft,  any Engine or
           any Part or to its design, testing or use or otherwise;

      (b)  which arise out of any act or  omission  which  invalidates  or which
           renders voidable any of the Insurances;

      (c)  which may at any time be suffered or incurred as a consequence of any
           design,  article or material in the Aircraft,  any Engine or any Part
           or its  operation  or use  constituting  an  infringement  of patent,
           copyright,  trademark,  design or other proprietary right or a breach
           of any obligation of confidentiality owed to any person;

                                       69
<PAGE>

      (d)  the  Lessee's  breach of any of its  representations,  warranties  or
           covenants  hereunder  or  any  other  Event  of  Default  under  this
           Agreement

      but excluding any Claim to the extent (and only to the extent that):

           (aa) it  arises  as  a  result  of  the  wilful  misconduct  or gross
                negligence of such  Indemnitee;

           (bb) it arises as a result of a material  breach by the Lessor of any
                of its  obligations  under  this  Agreement  or  the  Beneficial
                Owner's  breach  of its  covenants  under  its  Letter  of Quiet
                Enjoyment  (which did not result  from a breach by the Lessee of
                any of  its  representations,  warranties,  covenants  or  other
                obligations hereunder);

           (cc) it  constitutes  a Lessor  Tax or  constitutes or results solely
                from a Lessor Lien;

           (dd) it is  attributable  to an event occurring after the Expiry Date
                following  the  redelivery  of the Aircraft by the Lessee to the
                Lessor in full  compliance with the terms and conditions of this
                Agreement  (including  without  limitation,   in  the  condition
                required or  permitted  by the terms of this  Agreement,  to the
                extent  that  such  Claim  is  solely   attributable   to  acts,
                omissions,  events or circumstances (which are not the result of
                acts  or  omissions  of  the  Lessee,  its  employees,   agents,
                contractors  or other  representatives)  which  occur after such
                redelivery;

            (ee)it is the subject matter of another indemnity  provision of this
                Agreement or consists of a cost or expense imposed on the Lessor
                or the  Beneficial  Owner by the terms  hereof or is incurred by
                the Lessor or the  Beneficial  Owner or any other  Indemnitee in
                performing its express obligations hereunder;

           (ff) it  consists  of  costs,   fees  or  expenses   related  to  the
                negotiation,  preparation  or execution of this Agreement or any
                other document executed in connection herewith;

           (gg) it  consists  of  costs,  fees or  expenses  arising  out of the
                acquisition  or transfer by the Lessor or any  Indemnitee of any
                interest  in the  Aircraft  or this  Agreement  except  any such
                transfer in connection  with the exercise of remedies  hereunder
                in  accordance  with the terms of Clause 13.2  hereof  after the
                occurrence  of  an  Event  of  Default  or  as  a  result  of  a
                replacement of a Part or an Engine pursuant to the terms hereof;

                                       70
<PAGE>

           (hh) it arises out  of or  results from acts of any Indemnitee  prior
                to the Delivery Date;

           (ii) it  relates  to the  costs,  fees  and any  other  out-of-pocket
                expenses   incurred  in  connection   with  the   establishment,
                maintenance or  restructuring  of or charges to the financing or
                refinancing  of the  Aircraft,  any  Engine  or any  Part by any
                Indemnitee  (including without  limitation,  the Head Lessee) or
                the  creation or  maintenance  of the trust  estate  established
                under the Trust Agreement  (including,  without limitation,  any
                fees payable to the Owner Trustee).

      The following  shall apply to all claims for  indemnity  under this Clause
      10.1:

           (i)  If any  Indemnitee  has  actual  knowledge  of any  Claim hereby
                indemnified   against  it  shall  give  prompt   written  notice
                thereof to  the Lessee;  provided,  however, that the failure of
                an  Indemnitee  to  give  such  notice  shall  not  relieve  the
                Lessee  of  its  obligations  hereunder,  except  to the  extent
                that such  failure  impairs  the Lessee's  ability to contest or
                to  participate  in  the contest  of such Claim in any  material
                respect or materially increases the amount of such Claim.

           (ii) Each  claim  against  an  Indemnitee  by  a  third  party  which
                constitutes  a  Claim  shall,  if  reasonably  requested  by the
                Lessee,  be  contested  by  the  Indemnitee  in  good  faith  by
                appropriate   proceedings,   provided   that  the  Lessee  shall
                indemnify   such   Indemnitee  in  respect  of  any   reasonable
                out-of-pocket  fees, costs or expenses actually incurred by such
                Indemnitee  in  conducting  such  contest  and the amount of any
                interest or  penalties or any other losses which are required to
                be paid  as a  direct  result  of  contesting  such  Claim,  and
                provided further that such contest  proceedings would not result
                in the likelihood of the seizure, condemnation, sale, forfeiture
                or other  loss of the  Aircraft  or any  interest  therein or of
                criminal  liability  or  unindemnified  liability on the part of
                such  Indemnitee.   The  Lessee  shall  be  entitled  to  assume
                responsibility  for and  control of the  defense of any Claim in
                respect of which any  Indemnitee  (other than the Head Lessor or
                any  Bank)  makes a  claim  against  the  Lessee  for  indemnity
                pursuant  to this  Clause  10.1,  provided  that  (i) the  legal
                counsel  retained by the Lessee for such  purpose is  reasonably
                acceptable to such  Indemnitee  and (ii) the Lessee pursues such
                contest  diligently  and in good faith and, upon the  reasonable
                request  of  such  Indemnitee,  provides  such  Indemnitee  with
                reasonable  details of the status of the  contest  and copies of
                all legal  briefs,  court  filings  and,  subject to  applicable
                considerations of legal privilege,  counsel's memoranda relevant
                to such contest. In the event that (1) an Event of Default shall
                have  occurred  and be  continuing  or (2) the  Lessee  fails to


                                       71
<PAGE>

                comply with the foregoing  requirements in any material respect,
                the  applicable  Indemnitee  may,  if such  Event of  Default or
                failure, as the case may be, continues after such Indemnitee has
                given  the  Lessee  a  reasonable   opportunity  to  effect  the
                applicable level of compliance,  reassume responsibility for and
                control of the relevant contest,  which, in such  circumstances,
                such Indemnitee  agrees to pursue  diligently and in good faith.
                To the  extent  the  Lessee  is  entitled  to  defend  any Claim
                hereunder, the Indemnitee shall cooperate in good faith with the
                Lessee  and may  participate  (with  its own  counsel,  if it so
                desires) at such Indemnitee's sole cost and expense.

           (iii)Each Indemnitee shall supply the Lessee with such information as
                the Lessee shall reasonably  request to defend or participate in
                any proceeding permitted by this Clause 10.1.

           (iv) No Indemnitee  shall enter into a settlement or other compromise
                or consent to a judgment  with respect to any Claim  without the
                prior written consent of the Lessee,  which consent shall not be
                unreasonably withheld or delayed,  unless such Indemnitee waives
                its rights with  respect to such Claims  under this Clause 10.1;
                provided  that the payment of an amount to which a Claim relates
                when  legally  compelled  to  do so by a  Government  Entity  of
                competent  jurisdiction  after  which a request for a refund (if
                not  prohibited by law) of such amount is diligently  pursued by
                appropriate  procedures  in  accordance  with the  terms of this
                Clause 10.1 will not be considered a  settlement,  compromise or
                consent to judgment requiring the Lessee's prior consent.

           (v)  In the event  the  Lessee shall be  obligated  to indemnify  any
                Indemnitee  pursuant to  this  Clause  10.1,  the  Lessee  shall
                (provided no Event of Default  shall  have occurred  and then be
                continuing)   be    subrogated   (without   warranty    by   the
                Indemnitee)  to the  rights of  such  Indemnitee  in  respect of
                the matter  as to which  the indemnity  was paid (except  rights
                under such  Indemnitee's  own  insurance  policies or under  the
                indemnification   provisions  of  the Head  Lease  or any  other
                documents  or agreements  relating  to the Aircraft  between the
                Head  Lessor  and  the  Banks)  and  may  pursue the same at the
                Lessee's  expense.  If any  Indemnitee  shall  obtain a recovery
                of all or any part of any  amount  which  the Lessee  shall have
                paid  to such  Indemnitee  or for which  the  Lessee  shall have
                reimbursed  such  Indemnitee  pursuant to this Clause 10.1, such
                Indemnitee  shall   promptly  (or  if  such  Indemnitee  is  the
                Lessor,  at such time as no  Event of Default may have  occurred
                is then  continuing)  pay or  cause to be  paid to the Lessee an
                amount  equal  to such  recovery  (but  only  up to  the  amount
                previously paid by the Lessee to such Indemnitee).

10.2  DURATION

      The  indemnities  contained in this  Agreement will continue in full force
      after the Expiry Date.

11.   EVENTS OF LOSS

11.1  TOTAL LOSS

      (a)  PRE-DELIVERY:  If a  Total  Loss  occurs  prior  to   Delivery,  this
           Agreement  will  immediately   terminate  and,  except  as  expressly
           stated in  this  Agreement,  neither  party  will  have  any  further
           obligation  or  liability   under  this  Agreement  other   than  the
           obligation  of  the Lessor to  return to the Lessee  that  portion of
           the  Commitment  Fee  that has been  paid to the  Lessor,  if paid in
           cash, or to return the  Letter of Credit,  if the  Commitment  Fee is
           in the form of a Letter of Credit.

      (b)  POST-DELIVERY:  If a Total  Loss occurs  after  Delivery,  the Lessee
           will pay  the Agreed Value (minus  all  insurance  proceeds  received
           by the Lessor  or paid  to a third  party  pursuant  to the  Lessor's
           instruction   in  respect  of such  Total  Loss) to  the Lessor on or
           prior to the  earlier  of (i) ninety  (90) days  after the Total Loss
           Date and (ii) the  date of receipt of insurance   proceeds in respect
           of that  Total Loss (the  "SETTLEMENT  DATE") unless  the Aircraft is
           restored  to  the Lessor or the  Lessee  within  that  period (or, in
           the  case  of a   Total  Loss  coming  within   paragraph  (c) of the
           definition  of  Total Loss and  involving the loss of the Lessor's or
           the Head  Lessor's,  as the  case may be, title  to the Aircraft,  if
           both the Aircraft  and  title  thereto are  restored to the Holder of
           Legal Title or, in the  case of the  Aircraft,  to the  Lessee).  The
           receipt by the  Lessor of the  insurance  proceeds  in respect of the
           Total  Loss  shall,  to the  extent of such  proceeds,  discharge  or
           partially  discharge  the  Lessee  from  its  obligation  to  pay the
           Agreed  Value to  the Lessor  pursuant  to  this  sub-clause  (b). In
           the event  that the Lessor  received  insurance proceeds with respect
           to such  Event of Loss (or  such  proceeds  were paid as  directed by
           the  Lessor)  after  the  Lessee  has  paid the  Agreed  Value to the
           Lessor,  the Lessor  shall pay or cause to be paid  to the Lessee the
           amount of  such  insurance  proceeds  (less any  amounts which are or
           will  become due  to the  Lessor  from  the  Lessee  hereunder)  plus
           monthly  interest  at  the  rate  equal  to  LIBOR  from  the date of
           receipt  of  such  insurance  proceeds by the Lessor (or by the party
           to  whom such  proceeds  are  paid as  directed by the Lessor) to the
           date such  insurance  proceeds are paid over  to the Lessee.  In the
           event that the insurance  proceeds are paid initially  to the Lessee
           and not to the Lessor,  the  amount, if any, by which  such insurance
           proceeds  together  with other  amounts,  if any, paid  by the Lessee
           to the  Lessor with  respect to  the Lessee's  obligation  to pay the
           Agreed  Value, or any  portion  thereof,  exceed the Agreed Value may
           be  retained  by  the  Lessee,  otherwise  the  Lessee  shall pay the


                                       73
<PAGE>

           Agreed Value to  the Lessor not later  than the  Settlement  Date. In
           the event  that  the Lessee  pays  the Agreed  Value to the Lessor in
           accordance  with  this  sub-clause  (b), the  Lessor  shall  promptly
           assign to  the Lessee  its rights  under  the  Insurances  to receive
           the insurance  proceeds in  respect of the Total  Loss (to the extent
           that  such  proceeds  shall  not  have  been  paid  to  the  Lessee).
           Subject  to the  rights  of any  insurers  and  reinsurers  or  other
           third  party,  upon  payment in full to the Lessor of that amount and
           all  other  amounts  which are or will  become  payable to the Lessor
           under   this  Agreement,   the  Lessor   will,  without  recourse  or
           warranty  (except  as to  the  absence of Lessor  Liens),  convey and
           transfer,  or cause  to be conveyed  and  transferred,  to the Lessee
           by instrument in  form and substance  reasonably  satisfactory to the
           Lessee full  legal and  beneficial  title to  the Aircraft and to any
           Engines or Parts not  installed  when the  Total Loss  occurred,  all
           on an "as-is  where is" basis,  and  will,  at the Lessee's  expense,
           execute and  deliver,  or cause to be  executed and  delivered,  such
           bills of  sale and  other  documents  and  instruments  as the Lessee
           may  reasonably   request  to  evidence  (on  the  public  record  or
           otherwise)  the   transfer  and   conveyance  of  such  title  to the
           Aircraft and  such  Engines and Parts to  the Lessee,  free and clear
           of all rights of the Lessor and any Lessor Liens.

      (c)  ENGINE  LOSS:  Upon the  occurrence  of  an Engine  Loss  (including,
            for the   avoidance  of  doubt,  at   time  when the  Engine  is not
           installed  on the Airframe) in  circumstances  in which there has not
           also  occurred  a  Total  Loss,  the  Lessee  shall  give  the Lessor
           written  notice  promptly upon  becoming aware of the same  and shall
           within  days  after  the  Engine  Loss  Date,  convey  or cause to be
           conveyed  to  the  Holder  of  Legal  Title as  replacement  for such
           Engine,  title,  free  and  clear  of all  Security  Interests,  to a
           replacement  engine complying with  the conditions  set out in Clause
           8.13(a).  The Lessee shall, at  the time of such  conveyance,  comply
           in all respects  with Clause  8.17(a) so that the replacement  engine
           becomes an  Engine,  whereupon  the leasing  of the  replaced  Engine
           the  subject   of the  Engine  Loss  shall  cease  and  title to such
           replaced   Engine shall  (subject to any  salvage rights of insurers)
           be  conveyed  to  the  Lessee  pursuant  to  Clause  8.17(c).  If the
           Lessor  receives  any  insurance   proceeds  relating  to such Engine
           Loss,  the   Lessor  shall   promptly  remit  such  proceeds  to  the
           Lessee.  No   Engine  Loss  with  respect  to  any  Engine  which  is
           replaced in  accordance  with the  provisions of  this Clause 11.1(c)
           shall  result  in  any  increase  or  decrease  in Rent or the Agreed
           Value.

11.2  REQUISITION

      During any requisition for use or hire of the Aircraft, any Engine or Part
      which does not constitute a Total Loss:

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

                                       74
<PAGE>

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

11.3  APPLICATION  OF  PAYMENTS  FROM  GOVERNMENTAL  AUTHORITIES  IN  RESPECT OF
      EVENT OF LOSS.

      Any payments  (other than  insurance  covered by Clause 9) received at any
      time by the  Lessor  or the  Lessee  from any  Government  Entity or other
      person with  respect to an Event of Loss with  respect to the  Aircraft or
      any Engine will be applied as follows:

      (a)  if  such  payments  are  received  with   respect to an Event of Loss
           relating   to the  Airframe  or the  Airframe  and  the  Engines  or
           engines  installed on such Airframe,   (A) so much of such payment as
           shall not  exceed the Agreed  Value  due under Clause  11.1(b)  shall
           be  applied (i) in  reduction of the Lessee's  obligation to pay such
           amount,  if  not  already  paid by the Lessee,  or (ii) if the Agreed
           Value is  already  paid by the Lessee  to the  Lessor,  to  reimburse
           the Lessee for its  payment of such  amount, and (B) the balance,  if
           any,  of  such   payment  remaining  thereafter  to  the  extent  not
           exceeding the Lessee's  Interest  shall  be paid to  the Lessee,  and
           (C) the balance, if any, of such  payment  remaining  thereafter will
           be paid over to or retained by the Beneficial Owner; and

      (b)  if such  payments  are  received  with  respect  to an  Engine  under
           circumstances  contemplated by Clause 11.1(c), such payments shall be
           paid over to, or retained  by, the Lessee,  provided  that the Lessee
           shall have  fully  performed  or  concurrently  therewith  will fully
           perform the requirements of Clause 11.1(c).

12.   RETURN OF AIRCRAFT

12.1  REDELIVERY

      On the Expiry Date or  termination  of the leasing of the  Aircraft  under
      this Agreement,  the Lessee will, unless a Total Loss has occurred, at its
      expense,  redeliver  the Aircraft and Aircraft  Documents to the Lessor at
      the Redelivery Location or such other airport as is mutually acceptable to
      the parties  hereto,  in a condition  complying  with Schedule 3, free and
      clear of all Security  Interests  and  Permitted  Liens (other than Lessor


                                       75
<PAGE>

      Liens), in a condition  qualifying for immediate issuance of a Certificate
      of   Airworthiness   by  the  FAA  and  complying  with  the   operational
      requirements of FAR Part 121, or as otherwise agreed by the Lessor and the
      Lessee.

12.2  FINAL INSPECTION

      During the 15 days  immediately  prior to redelivery of the Aircraft,  the
      Lessee  will make the  Aircraft  available  to the Lessor  for  inspection
      ("FINAL INSPECTION") in order to verify that the condition of the Aircraft
      complies with this Agreement.  The Final Inspection will be long enough to
      permit the Lessor to inspect:

      (a)  the Aircraft Documents;

      (b)  the Aircraft and uninstalled Parts; and

      (c)  the Engines, including without limitation (i) at the Lessee's cost, a
           video-taped  borescope  inspection  of (A) the low  pressure and high
           pressure compressors and (B) the turbine area, all performed,  at the
           Lessor's option, by engine  manufacturer,  (ii) at the Lessee's cost,
           an engine  condition  run of each  Engine,  and (iii)  magnetic  chip
           inspection.

      At  the   Lessor's   request,   the  Lessee   shall  permit  the  Lessor's
      representatives  reasonable  access to the Aircraft.  Notwithstanding  the
      preceding sentence, the Lessor shall not open any panels, bays or the like
      or  disassemble  any  components   which  are  not  otherwise   opened  or
      disassembled  or removed in the course of the Lessee's  maintenance of the
      Aircraft  unless  the  Lessor has  reasonable  cause to  believe  that the
      relevant  portion of the  Aircraft or component  may not be in  compliance
      with the return conditions as set forth in Schedule 3 hereof.  The cost of
      opening,  inspecting  and  closing  any such  areas  shall be borne by the
      Lessor  unless  such  action  reveals  any  discrepancies  from the return
      conditions  required  by this  Clause 12 and  Schedule 3 in which case the
      cost of opening,  inspecting and closing any such areas and the correcting
      such discrepancies shall be borne by the Lessee.

      The Lessor shall also be  entitled,  as part of the Final  Inspection,  to
      require  the  Lessee  to  perform  a 2 hour  demonstration  flight  at the
      Lessee's cost (with the Lessor's  representatives as on-board  observers).
      In the event that a defect is discovered during such demonstration  flight
      and the Boeing test flight guide requires an in-flight verification of the
      correction  of such  defect,  the Lessee will,  at the  Lessee's  expense,
      perform an additional  demonstration flight (or flights, as applicable) to
      the extent  required for the sole purpose of verifying  the  correction of
      such defect.

      On redelivery, the Lessee will comply with Clause 8.17(b) hereof.

                                       76
<PAGE>

      The Lessee shall  indemnify  and hold  harmless the  Indemnitees  from and
      against any and all liabilities,  damages and losses  (including costs and
      expenses  incidental  thereto) arising by reason of death or injury to any
      observer  or  employee  of the  Lessee,  arising  out  of,  or in any  way
      connected  with such  demonstration  flight  and Final  Inspection  of the
      Aircraft.

      The Lessor shall  indemnify  and hold harmless the Lessee from and against
      any and all liabilities,  damages and losses (including costs and expenses
      incidental  thereto) arising by reason of death or injury to any observer,
      representative  or employee of the Lessor or any  Indemnitee,  arising out
      of,  or  in  any  connected  with  such  demonstration  flight  and  Final
      Inspection of the Aircraft.

12.3  NON-COMPLIANCE

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

      (a)  immediately  rectify  the  non-compliance  and,  to  the  extent  the
           non-compliance  extends  beyond  the  Expiry  Date,  the Term will be
           automatically  extended and this Agreement will remain in force until
           the non-compliance has been rectified; or

      (b)  redeliver the Aircraft to the Lessor and  indemnify  the Lessor,  and
           provided  that the Lessor  shall have  security  for that  indemnity,
           against the cost of putting the Aircraft into the condition  required
           by   this   Agreement,    provided   that,    notwithstanding    such
           non-compliance,  the Aircraft is in such  condition as to allow it to
           be immediately placed into commercial passenger service.

      Notwithstanding  the  Lessee's  election of the option set forth in clause
      (a)  above,  if the Lessor so directs  the Lessee in  writing,  the Lessee
      shall  redeliver  the  Aircraft  to the  Lessor and  indemnify  the Lessor
      against the cost of putting the Aircraft  into the  condition  required by
      this  Agreement,  in which  case the Term of this  Agreement  shall not be
      extended as provided in such clause (a).

12.4  OBLIGATION TO RETURN THE AIRCRAFT

      Except  with  respect to the  return of the  Aircraft  pursuant  to Clause
      12.3(b) and as otherwise  provided in Clause  12.3,  the failure to return
      the  Aircraft  at the Expiry  Date in full  compliance  with Clause 12 and
      Schedule 3 of this Agreement, for any reason, shall result in an extension
      of the Term,  and this  Agreement  remaining  in full  force  and  effect,
      including the Lessee's  obligation to pay Rent (which the Lessee shall pay
      on a per diem basis weekly in arrears); provided, however, that the Lessee
      shall not operate,  or permit others to operate  (except during any period


                                       77
<PAGE>

      described  in the  definition  of Total  Loss in which  possession  of the
      Aircraft  is held by a third  party) the  Aircraft  after the Expiry  Date
      except for testing and acceptance  flights  pursuant to Clause 12.2 hereof
      and a ferry flight to the Redelivery  Location and shall  promptly  return
      the Aircraft to the Lessor after such non-compliance is rectified.  Except
      as expressly set forth in this Agreement,  the Lessee has no right to keep
      the Aircraft beyond the Expiry Date.

12.5  APU ADJUSTMENT

      APU shall be adjusted as set forth in Letter Agreement No. 1.

12.6  DOCUMENTATION

      Upon redelivery the Lessee shall reasonably  assist and cooperate with the
      Lessor, to the extent reasonably requested by the Lessor, in obtaining all
      documents  necessary  to  export  the  Aircraft  from  the  Habitual  Base
      (including,  without limitation, a valid and subsisting export license for
      the  Aircraft)  and  required  in relation  to the  deregistration  of the
      Aircraft with the Aviation Authority.

12.7  ACKNOWLEDGEMENT

      Upon  redelivery  of the  Aircraft  by the  Lessee  to the  Lessor  at the
      Redelivery  Location  in  accordance  with  and in  compliance  with  this
      Agreement,  the  Lessor  will  deliver  to the  Lessee  an  acknowledgment
      confirming  that the Lessee has  redelivered the Aircraft to the Lessor in
      accordance with this Agreement.

12.8  MAINTENANCE PROGRAMME

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

      (b)  The Lessee will,  if requested by the Lessor to do so, upon return of
           the Aircraft deliver to the Lessor a current and complete copy of the
           Agreed Maintenance Programme.

      (c)  The  Lessor  agrees  that  it will   not  disclose,  and will use its
           reasonable  efforts to ensure  that no other  person  receiving  such
           Maintenance  Programme  from or through  the  Lessor  discloses,  the
           contents  of  the  Agreed   Maintenance  Programme  to any  person or
           entity  except  to  the  extent  necessary  to monitor  the  Lessee's
           compliance  with  this  Agreement  and/or  to bridge the  maintenance
           programme  for the  Aircraft from  the Agreed  Maintenance  Programme
           to another programme after the Expiry Date.

                                       78

12.9  FUEL

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

12.10 STORAGE

      If  the  Lessor  so  requests,  and  subject  to the  availability  of the
      requisite space, the Lessee shall, at the Lessor's expense, park and store
      the  Aircraft  at the  Redelivery  Location  on behalf of the Lessor for a
      period not exceeding 120 days from the Expiry Date. During that period the
      Aircraft  shall be at the  Lessor's  risk  (save as to any loss or  damage
      caused by the Lessee's wilful misconduct or recklessness),  but the Lessee
      shall continue to maintain and insure the Aircraft in accordance  with the
      maintenance  and insurance  provisions of this  Agreement.  All reasonable
      storage, maintenance and insurance costs incurred by the Lessee (excluding
      any profit element  accruing to the Lessee)  pursuant to this Clause 12.10
      shall be reimbursed by the Lessor promptly upon presentation of supporting
      invoices and/or receipts.

                assignment  for the  benefit of  creditors  or workout  with its
                creditors  generally,  or  the  reorganization,  rehabilitation,
                administration,  liquidation,  or dissolution of the Lessee,  or
                any corporate action (including,  without limitation,  any board
                of  directors or  shareholder  action) is taken by the Lessee in
                furtherance of any of the foregoing,  whether or not the same is
                fully effected or accomplished.

      (i)  SUSPENSION OF BUSINESS: the Lessee suspends or ceases or threatens in
           writing to suspend  or cease to carry on its  business  such that the
           ability  of the  Lessee to  perform  its  obligations  hereunder  may
           reasonably be expected to be materially adversely affected; or

      (j)  DISPOSAL:  the Lessee disposes,  conveys or transfers or threatens in
           writing to dispose,  convey or transfer of all or a substantial  part
           of its  assets,  other than for the  purpose of a  reconstruction  or


                                       81
<PAGE>

           amalgamation the terms of which have received the previous consent in
           writing  of the  Lessor  and such  disposition  would have a material
           adverse   effect  on  the  ability  of  the  Lessee  to  perform  its
           obligations hereunder; or

      (k)  RIGHTS:  the existence,  validity,  enforceability or priority of the
           rights of the Lessor as owner and  lessor in respect of the  Aircraft
           or the rights of the Banks as  assignee of this  Agreement  under the
           Assignment are challenged by the Lessee or any other person  claiming
           by or through the Lessee without appropriate cause; or

      (l)  DELIVERY:  the Lessee fails to accept  delivery of the Aircraft  when
           validly  tendered  pursuant to this Agreement by the Lessor at a time
           when the Lessee is  obligated  to accept the  Aircraft in  accordance
           with the terms hereof; or

      (m)  LETTER OF  CREDIT:  the  Letter of  Credit (i) ceases  for any reason
           to be in full force and effect,  or (ii) is  not renewed  or replaced
           at least 15 Business  Days  prior to its  expiry (so that the renewal
           or   replacement  becomes   effective   immediately   following  such
           expiry) or (iii) in  the event  such  Letter of  Credit is drawn upon
           by the Lessor  prior  to its  expiration,  such  Letter  of Credit is
           not (x)  reinstated  by the  Lessee to  its  original sum within five
           (5)  days  of  written  notice  by  the  Lessor,  or (y)  subject  to
           5.15(a),  replaced  by  a  cash  deposit  from   the  Lessee  in  the
           required amount of such Letter of Credit.

13.2  RIGHTS

      If an Event of Default  occurs,  the Lessor may at its option (and without
      prejudice to any of its other rights  under this  Agreement),  at any time
      thereafter:

      (a)  treat such event as a repudiation  by the Lessee of  its  obligations
           under this Agreement  and/or by  notice to the  Lessee with immediate
           effect   terminate   the  letting  of   the   Aircraft  (but  without
           prejudice  to the  continuing  obligations  of  the Lessee under this
           Agreement),   whereupon   all  rights   of  the  Lessee   under  this
           Agreement,  including,  without  limitation,  the Lessee's  rights to
           possession  and use  of the Aircraft  (other than for the purposes of
           redelivery  of the Aircraft  to or as directed by the Lessor),  shall
           cease; and/or

      (b)  proceed by appropriate court action or actions to enforce performance
           of this  Agreement  or to  recover  damages  for the  breach  of this
           Agreement; and/or

      (c)  either:

           (i)  take  possession of the  Aircraft,  for which purpose the Lessor
                may enter  any premises  belonging  to or in the  occupation  of
                or under  the  control of  the Lessee  (for  which  purpose  the


                                       82
<PAGE>

                Lessee  hereby  grants to  the Lessor  an  irrevocable  license)
                where the  Aircraft  may  be located,  or cause  the Aircraft to
                be redelivered  to the  Lessor at the  Redelivery   Location (or
                such  other  location  as  the  Lessor  may  require),  and  the
                Lessor is  hereby   irrevocably  authorized  and   empowered  to
                direct  pilots  of  the  Lessee  or  other  pilots  to  fly  the
                Aircraft  to  that  airport  and  will have all the  powers  and
                authorizations necessary for taking such action; or

           (ii) by serving notice,  require the Lessee to redeliver the Aircraft
                to the Lessor at the Redelivery Location (or such other location
                as the Lessor may require).

13.3  DEREGISTRATION

      If an Event of Default occurs,  the Lessor may sell or otherwise deal with
      the Aircraft as if this Agreement had never been made and the Lessee will,
      at the  request  of the  Lessor,  take all steps  necessary  to effect (if
      applicable) deregistration of the Aircraft and its export from the country
      where the  Aircraft  is for the time being  situated  and any other  steps
      necessary  to enable  the  Aircraft  to be  redelivered  to the  Lessor in
      accordance with this Agreement.

13.4  DEFAULT PAYMENTS

      If an Event of Default  occurs,  the Lessee will  indemnify  the Lessor on
      demand against any loss, damage,  expense,  cost or liability,  including,
      without  limitation,  all reasonable  attorneys'  fees and  disbursements,
      which the Lessor may sustain or incur  directly or indirectly as a result,
      including but not limited to:

           (i)  any  loss of  profit  suffered  by  the  Lessor  because  of the
                Lessor's  inability  to   place  the   Aircraft  on  lease  with
                another  lessee on terms as  favourable  to  the Lessor  as this
                Agreement  or  because  whatever  use,  if  any,  to  which  the
                Lessor  is able  to put the  Aircraft  upon  its  return  to the
                Lessor,  is  not  as   profitable  (calculated  on an  After-Tax
                Basis) to the  Lessor as  this  Agreement  would  have  been but
                for such Default or non-delivery;

           (ii) whether  or not  the  Lessor  shall  have  exercised,  or  shall
                thereafter at any time exercise,  any of its rights under Clause
                13.2 hereof with respect to all or any part of the Aircraft, the
                Lessor,  by written  notice to the Lessee  specifying  a payment
                date  not  earlier  than  ten  (10)  days  from the date of such
                notice,  may demand that the Lessee 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,  in lieu of the  installments  of Rent due on the
                Aircraft,   Airframe,   Engines  or  Part  thereof  for  periods
                commencing  on or  after  the  payment  date  specified  in such
                notice,  any  unpaid  Rent due for  periods  prior to the period
                commencing  with the payment  date  specified in such notice and


                                       83
<PAGE>

                other amounts owing under this  Agreement  (prorated in the case
                of Rent on a daily  basis),  including  interest  thereon at the
                Default Rate from the original date due under this  Agreement to
                and  including the payment date  specified in such notice,  plus
                the amount equal to the excess,  if any, of the present value of
                the  aggregate  of the  remaining  installments  of Rent for the
                remainder of the Term (determined without reference to any right
                of the Lessor to terminate the leasing of the Aircraft,  whether
                or not such right is  exercised)  over the present  value of the
                fair market  rental value of the Aircraft,  Airframe,  Engine or
                Part thereof, for the remainder of such Term, using in each case
                a  discount  rate of the  amount of  interest  then paid on U.S.
                Treasury bills of similar maturity;

           (iii)any amount of principal, interest, fees or other sums whatsoever
                paid or payable on account of funds  borrowed  in order to carry
                any amount unpaid by the Lessee;

           (iv) any loss,  premium,  penalty or expense which may be incurred in
                repaying  funds  raised to finance the  Aircraft or in unwinding
                any swap,  forward  interest rate  agreement or other  financial
                instrument  relating  in  whole  or  in  part  to  the  Lessor's
                financing of the Aircraft; and

           (v)  any loss, cost, expense  or liability  sustained or  incurred by
                or on behalf of  the Lessor,  together with  interest thereon at
                the  Default  Rate  from  the  date  such  cost  or  expense  is
                incurred  by  the   Lessor  until  the   date  of  reimbursement
                thereof by the  Lessee,  owing  to such  Event of  Default,  the
                exercise  of  remedies  hereunder  or  the  Lessee's  failure to
                redeliver  the  Aircraft  on the date,  at the  place and in the
                condition required by this Agreement.

      For the avoidance of doubt, the provisions of Clause 5.10(a) will apply to
      any sums payable by the Lessee pursuant to this Clause 13.4.

      For the purpose of Clause 13.4(ii)  above,  the "fair market rental value"
      of the  Aircraft,  the  Airframe,  any Engine or Part thereof shall be the
      rental value,  net of all costs and expenses of  recovering  the Aircraft,
      the Airframe or any Engine or Part thereon and  restoring its condition to
      the  condition  required  hereunder,  which  would be obtained in an arm's
      length transaction between informed and willing lessee and an informed and
      willing  lessor,  based  upon the actual  condition  and  location  of the
      Aircraft,  Airframe  or any Engine or Part  thereof,  which value shall be
      determined  by a  reputable  firm of aircraft  appraisers  selected by the
      Lessor,  the  Head  Lessor  or the  Beneficial  Owner.  The  cost  of such
      appraisal shall be borne by the Lessee.

13.5  EXERCISE OF REMEDIES

      Except as otherwise  expressly set forth herein,  no remedy referred to in
      Clause 13 is intended to be exclusive, but each shall be cumulative and in
      addition to any other remedy  referred to above or otherwise  available to
      the Lessor at law or in equity.  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.

      The  Lessor's  rights and the Lessee's  obligations  under Clause 13 shall
      survive the Expiry Date.

14.   ASSIGNMENT AND TRANSFER

14.1  NO ASSIGNMENT BY LESSEE

      The  Lessee  will not  assign or  create  or permit to exist any  Security
      Interest  over any of its rights  under this  Agreement  without the prior
      written consent of the Lessor.

14.2  ASSIGNMENT

      The Lessor may assign all or any of its rights,  title and interest  under
      this Agreement and in the Aircraft but in the case of an assignment (other
      than by way of security)  only to any Permitted  Transferee  provided that
      the  assignment or any act required of the Lessee in connection  therewith
      will not result in any  material  respect  (i) in the  deprivation  of any
      material  rights or  privileges  of the Lessee or (ii) an  increase of the
      Lessee's  obligations.  The  Lessor  will,  however,  in  the  case  of an
      assignment  (other  than by way of  security)  have no further  obligation
      under this Agreement with respect to periods  following such assignment of
      all its rights,  title and interest  under this  Agreement and will remain
      entitled to the benefit of each indemnity  under this Agreement  provided,
      in any such event, the Permitted Transferee assumes in writing in form and
      substance   reasonably   satisfactory  to  the  Lessee  all  the  Lessor's
      obligations  under  this  Agreement  including,  without  limitation,  all
      obligations  with  respect to acts and events  which  occur  prior to such
      assignment and will agree not to interfere,  except as otherwise permitted
      by this  Agreement,  with the quiet use,  possession  and enjoyment of the
      Aircraft  by  the  Lessee  or the  exercise  by the  Lessee  of its  right
      hereunder.

      The Lessee will, at the Lessor's cost, comply with all reasonable requests
      of the Lessor,  its successors and assigns in respect of the  consummation
      of any such assignment.  The Lessor will promptly notify the Lessee of any


                                       85
<PAGE>

      proposed assignment and, as a condition thereto,  shall obtain the written
      consent of the Lessee,  such  consent not to be  unreasonably  withheld or
      delayed, to any proposed assignment (other than by way of security) to any
      successor other than a Permitted Transferee.

14.3  NO INCREASED LIABILITY

      Any assignment or transfer by the Lessor  pursuant to Clause 14.2 shall be
      subject to the  condition  that the tax risk  exposure of the Lessee shall
      not, as a consequence of such  assignment or transfer,  be greater than it
      would have been in the absence of such assignment or transfer.

14.4  RIGHT TO GRANT MORTGAGE

      The Lessee shall co-operate with the Banks, the Lessor and the Head Lessor
      in taking or receiving a legal  mortgage or other  security  interest over
      the Aircraft or an assignment of the Lessor's  interest in the  Insurances
      or other  interest  of the Lessor in favour of the Banks as  security  and
      provide a written confirmation of its consent thereto, in each case, at no
      cost to the Lessee,  as may  reasonably be required in order to facilitate
      the  financing of the  acquisition  of the  Aircraft,  including,  without
      limitation,  the registration  and/or other perfection  and/or priority of
      such  mortgage  or  other   security   interest  and  shall  execute  such
      agreements, at no cost to the Lessee, as the Lessor or the Head Lessor may
      reasonably require for the purposes of effecting all necessary  amendments
      to this Agreement (including,  without limitation, Clauses 8, 9 and 10 and
      Schedule 4) subject,  in each case, to the same  limitations  set forth in
      Clause 14.3.

15.   ILLEGALITY

      If it is or becomes  unlawful in any relevant  jurisdiction for the Lessor
      or the Lessee to give effect to any of its material obligations under this
      Agreement or to continue this  Agreement,  the Lessor will consult in good
      faith with the Lessee as to any steps which may reasonably be taken (at no
      cost to the Lessor in the case of  illegality  with respect to the Lessee,
      and at no cost to the Lessee in the case of  illegality  of the Lessor) to
      restructure  the transaction in order to avoid such  unlawfulness.  In the
      event  that no such  steps  can  reasonably  be taken,  the  Lessor or the
      Lessee, as applicable,  may, by notice in writing to the other,  terminate
      the  leasing of the  Aircraft  under this  Agreement  and the Lessee  will
      forthwith  redeliver the Aircraft to the Lessor in accordance  with Clause
      12.

16.   MISCELLANEOUS

16.1  WAIVERS, REMEDIES CUMULATIVE

      The rights of either party under this Agreement:

                                       86
<PAGE>

      (a)  may be exercised as often as necessary;

      (b)  are  cumulative  and not  exclusive of that party's  rights under any
           law; and

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

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

16.2  DELEGATION

      The Lessor may  delegate  to any person or persons  (other than an airline
      competing with the Lessee,  an Affiliate of such an airline or an employee
      or representative  of either thereof) all or any of the trusts,  powers or
      discretions  vested in it by these presents and any such delegation may be
      made upon such  terms  and  conditions  and  subject  to such  regulations
      (including  power to sub-delegate) to a person eligible to be delegated by
      the Lessor as the Lessor in its reasonable discretion thinks fit.

16.3  CERTIFICATES

      Any certificate or  determination by the Lessor as to any rate of interest
      or as to any other  amount  payable  under  this  Agreement  will,  at the
      request of the Lessee be subject to  verification  in accordance  with the
      procedures set forth in Clause 5.16.

16.4  APPROPRIATION

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

16.5  CURRENCY INDEMNITY

      (a)  If the Lessor receives an amount in respect of the Lessee's liability
           under this  Agreement or if such liability is converted into a claim,
           proof,  judgment or order in a currency  other than the currency (the
           "CONTRACTUAL  CURRENCY")  in which  the  amount  is  expressed  to be
           payable under this Agreement:

           (i)  the  Lessee  will  indemnify  the  Lessor,   as  an  independent
                obligation,  against  any loss  arising out of or as a result of
                such conversion;

           (ii) if the amount  received by the Lessor,  when  converted into the
                contractual  currency (at the market rate at which the Lessor is
                able on the relevant date to purchase the  contractual  currency
                in London or, at its option,  New York with that other currency)
                is less than the amount owed in the  contractual  currency,  the


                                       87
<PAGE>

                Lessee will, forthwith on demand, pay to the Lessor an amount in
                the contractual currency equal to the deficit; and

           (iii)the Lessee will pay to the Lessor on demand any  exchange  costs
                and Taxes payable in connection with the conversion.

      (b)  The Lessor hereby agrees to indemnify  the Lessee  mutatis  mutandis,
           with respect to the matters set forth above in Clause 16.5(a).

      (c)  The Lessee and the  Lessor  each  waives any right it may have in any
           jurisdiction  to pay any amount  under this  Agreement  in a currency
           other than that in which it is expressed to be payable.

16.6  SET-OFF

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

16.7  SEVERABILITY

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

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

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

16.8  REMEDY

      If the Lessee fails to comply with any  provision of this  Agreement,  the
      Lessor may,  without being in any way obliged to do so or responsible  for

               connection with this Agreement;

               suit on the judgment or otherwise as permitted by applicable law,
               a certified or true copy of which shall be conclusive evidence of

               the Lessee or the Lessor;

      (e) Nothing in this clause limits the right of the Lessor or the Lessee to

          THEREBY  OF  THE   LESSOR/LESSEE   RELATIONSHIP   BEING   ESTABLISHED,
          including, without limitation, contract claims, tort claims, breach of
          duty claims and other common law and statutory claims.  The Lessor and

          waives its jury trial rights  following  consultation  with such legal
          counsel.  THIS WAIVER IS  IRREVOCABLE,  AND THIS WAIVER SHALL APPLY TO
          ANY SUBSEQUENT AMENDMENTS,  RENEWALS,  SUPPLEMENTS OR MODIFICATIONS TO

16.13 SOLE AND ENTIRE AGREEMENT

      This Agreement is the sole and entire agreement between the Lessor and the
      Lessee in relation  to the leasing of the  Aircraft,  and  supersedes  all
      previous agreements in relation to that leasing.  The terms and conditions
      of this Agreement can only be varied by an instrument in writing  executed
      by both parties or by their duly authorised representatives.

16.14 INDEMNITIES

      All rights expressed to be granted to each Indemnitee under this Agreement
      (other than the Lessor) are given to the Lessor as agent for and on behalf
      of that Indemnitee.

16.15 COST OF LESSEE'S WORK

      Whenever the Lessee itself performs work on the Aircraft (whether pursuant
      to Clauses 7.2,  8.11(e) or otherwise)  and is entitled,  pursuant to this
      Agreement,  to receive reimbursement from the Lessor of all or part of the
      cost of  performing  such  work,  the  Lessee  agrees  that it will  claim
      reimbursement  of the actual  cost to it of  carrying  out the work at its
      then prevailing fully burdened cost (provided always that such actual cost
      is reasonable  when compared with the cost typically  charged for carrying
      out the same or substantially the same work by similar  organisations) and
      not at the rate or rates charged by it at the time for the same or similar
      work undertaken for third parties.

16.16 COUNTERPARTS

      This  Agreement  may be  executed  in  counterparts  each  of  which  will
      constitute one and the same document.

16.17 ENGLISH LANGUAGE

      All  notices to be given  under this  Agreement  will be in  English.  All
      documents  delivered pursuant to this Agreement will be in English,  or if
      not in English, will be accompanied by a certified English translation. If


                                       93
<PAGE>

      there is any  inconsistency  between the English version of this Agreement
      and any version in any other language, the English version will prevail.

16.18 CONFIDENTIALITY

      Neither the Lessor nor the Lessee shall, without the other's prior written
      consent,  communicate  or  disclose  the  terms of this  Agreement  or any
      information or documents  furnished  pursuant to this Agreement (except to
      the extent that the same are within the public  domain) to any third party
      (other than their respective external legal advisers,  auditors, insurance
      brokers and/or underwriters, the Airframe and/or Engine manufacturers, the
      Head  Lessor and the  Banks)  PROVIDED  HOWEVER  that  disclosure  will be
      permitted, to the extent required:

      (a) pursuant to an order of any court of competent jurisdiction; or

      (b) pursuant  to  any   procedure   for  discovery  of  documents  in  any
          proceedings before any such court; or

      (c) pursuant to any law or regulation having the force of law; or

      (d) pursuant  to  a  lawful   requirement  of  any  authority  with  whose
          requirements the disclosing party is legally obliged to comply; or

      (e) in order to perfect any assignment of any assignable warranties.

16.19 GENEVA CONVENTION

      To the extent  permitted by any  applicable  law, if and when the State of
      Registration shall ratify the Convention on the International  Recognition
      of Rights in Aircraft signed at Geneva, Switzerland, on June 19, 1948, the
      Lessee  shall,  at its own cost,  do any and all things  necessary  in the
      State of  Registration  to perfect  recognition of the rights of the Title
      Holder by every signatory state which has ratified such Convention.

16.20 CIVIL RESERVE AIR FLEET PROGRAM

      So long as no Significant  Default or Event of Default has occurred and is
      continuing, the Lessee may subject the Aircraft, the Airframe or an Engine
      to the Civil  Reserve Air Fleet  Program and  transfer  possession  of the
      Airframe or an Engine to the United  States  government,  or any agency or
      instrumentality  thereof,  pursuant to the Civil Reserve Air Fleet Program
      so long as (i) the Lessee shall promptly notify the Lessor upon subjecting
      the  Airframe  or an Engine to the Civil  Reserve  Air Fleet  Program  and
      provide the Lessor with a name and address of the appropriate  contracting


                                       94
<PAGE>

      officer  representative  for the  Military  Airlift  Command of the United
      States Air Force,  (ii) the Lessee shall promptly notify the Lessor of any
      such transfer and (iii) the period of such transfer does not extend beyond
      the end of the  Term.  Except as  expressly  provided  herein,  all of the
      Lessee's  obligations  under this Agreement  shall continue and the Lessee
      shall remain  primarily  liable for the performance of all of the terms of
      this  Agreement  to the same extent as if the  Aircraft  had never  become
      subject to such Civil Reserve Air Fleet Program.

16.21 SECTION 1110

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

16.22 ARTICLE 2-A OF THE UCC

      The  parties  hereto  agree  that this  Agreement  as  extended,  amended,
      modified, renewed or supplemented, shall be governed by Article 2-A of the
      Uniform Commercial Code of New York.

          Insurances  are  subject  to a  security  assignment  in favour of the
          Banks, if applicable;

      (d) provide that,  in relation to the interests of each of the  additional
          assureds,  the  Insurances  will  not be  invalidated  by  any  act or

          terms  conditions  or warranty  of the  policy/ies  PROVIDED  THAT the

          thereof,  the Insurance can only be cancelled or materially altered in
          a manner  adverse  to the  additional  assureds  by giving at least 30
          days'  written  notice to the  Lessor,  the Head Lessor and the Banks,
          except  in the  case  of  radioactive  contamination  as  per  Lloyd's
          endorsement  AVN 38A or its  equivalent,  for  which  7 days'  written
          notice (or such lesser period as is or may be customarily available in
          respect thereof) will be given;

          reinsured  had  (immediately   before  such  bankruptcy,   insolvency,
          liquidation,   dissolution  or  similar  proceedings)  discharged  its
          obligations in full under the original  insurance  policies in respect

                a total loss or other  claim  where,  as  provided  by the Lease

                loss payee under the primary insurances, the Reinsurers will, in
                lieu of payment to the Reinsured, its successors in interest and
                assigns,  pay to the person  named as sole loss payee  under the
                primary insurances effected by the Reinsured that portion of any
                loss for which the Reinsurers  would  otherwise be liable to pay
                the Reinsured  (subject to proof of loss),  it being  understood
                and agreed that any such payment by the Reinsurers  will (to the
                extent  of  such  payment)  fully   discharge  and  release  the
                Reinsurers  from any and all  further  liability  in  connection
                therewith".

Dear Sirs,

We acknowledge receipt of a Notice of Assignment dated ____________________ (the
"ASSIGNMENT  NOTICE")  relating  to an  assignment  (the  "ASSIGNMENT")  between
_________________  (the  "ASSIGNOR")  and you. We  acknowledge  that we will not
challenge the effectiveness of the Assignment to confer on you all rights, title
and interest of the Assignor under the Aircraft Lease  Agreement dated June ___,
1997  between  Assignor  and  ourselves  (the  "LEASE") in respect of one Boeing
737-300  aircraft  with  manufacturer's  serial  number 28871  together with the
installed __________________ engines.

In consideration of payment to us of $1 and the issue to us of a quiet enjoyment
letter, receipt of which we hereby acknowledge, we hereby agree as follows:

If you issue to us a notice (a the "LESSOR DEFAULT  NOTICE") that your rights as
assignee  under the  Assignment  have become  exercisable we agree that we shall
thereafter:

(a)    pay to you at such  account as you may  nominate  all  rentals  and other
       amounts from time to time payable by us under the Lease;

(b)    perform,   observe  and  comply  with  all  our  other  undertakings  and
       obligations under the Lease in your favour and for your benefit as if you
       were named as the Lessor therein instead of the Assignor; and

(c)    if you so request,  enter into a lease with you or your  nominee,  on the
       same terms  (mutatis  mutandis) as the Lease,  provided that the Lease is
       thereby terminated.

If the  Assignor  is in breach of any of its  obligations,  express or  implied,
under the Lease,  or if any event  occurs  which would  permit us to  terminate,
cancel or surrender the Lease we will:

(a)    promptly upon  becoming  aware of it, give you notice of such breach or
       event;

                                      117
<PAGE>


(b)    accept as adequate remedy for any such breach  performance by you of such
       obligations  within 7 days of our written  notice to you,  provided  that
       such  performance  by you fully  compensates  the Lessee for any damages,
       costs and  expenses  suffered  or incurred by the Lessee as the result of
       such breach; and

(c)    if you so request,  enter into a lease with you or your  nominee on terms
       identical  to the Lease,  mutatis  mutandis,  provided  that the Lease is
       hereby terminated.

We agree  that  after  issue by you of any Lessor  Default  Notice,  we will not
recognise the exercise by the Assignor of any of its rights and powers under the
Lease unless and until requested to do so by you.

We agree that you will have the  benefit  of Clause 10 of the Lease  (Indemnity)
and  agree  that we are  bound by the  terms of such  clause  for your  benefit,
provided that you agree that you are also bound by the terms of such clause,  in
each case, as though the same were set out herein in full, mutatis mutandis.

Yours faithfully,

such rights  during the term of the Lease and  provided  that at or prior to the
time of such disposal a  Significant  Default or an Event of Default (as defined
in the Lease) has not occurred and is continuing the undersigned will dispose of
the  Aircraft  expressly  subject  to the  Lease  and  procure a letter of quiet
enjoyment  with the same  terms  (mutatis  mutandis)  as this  letter  from such

                  warranty  (except as to title) and  subject to the  exclusions
                  from warranties set forth in Article 4.1.

         ii.      OTHER   CONDITIONS.   The  conditions  set  forth  in  Article
                  2.1.1(i), (ii) and (iv) and in Article 2.1.2(i)(F) and (G) and
                  in Article  2.1.2(ii)(A) and (C), in each case with respect to
                  Lessor and Beneficiary, mutatis mutandis, shall have been met.
                  In addition,  Lessee shall have  received  from  Beneficiary a
                  certificate,  dated as of the Delivery Date,  confirming  that
                  the  representation  and warranty of Beneficiary  set forth in
                  Article 8.2 of the Lease is true and accurate.

2.2   TIME OF DELIVERY.

      Subject to the provisions of the next paragraph and satisfaction or waiver
      of the  conditions  set  forth  in  Article  2.1,  the  Aircraft  shall be
      delivered to Lessee,  and Lessee shall accept  delivery of the Aircraft on
      or about  November 25, 1997 (the  "Scheduled  Aircraft  Delivery") or such
      earlier or later date  agreed  mutually  in  writing  by  Beneficiary  and
      Lessee.  Beneficiary  shall give  Lessee at least 48 hours  prior  written
      notice of the proposed  delivery of the  Aircraft.  The  pre-delivery  and
      delivery  procedures  are  described  in  Exhibit  "D"  hereto.   Lessee's
      acceptance of delivery of the Aircraft shall be evidenced by the execution
      by Lessee and Lessor of a Lease  Supplement  substantially  in the form of
      Exhibit "A" hereto.

      If KG  expects  to be unable to cause  Lessor  to tender  delivery  of the
      Aircraft  to Lessee on the  Scheduled  Aircraft  Delivery  date,  KG shall
      notify Lessee as soon as practicable  prior  thereto.  If Lessor shall not
      have tendered the Aircraft for delivery to Lessee by December 25, 1997 for
      any reason  other than the  failure of Lessee to fulfill  its  obligations
      hereunder,  Lessee  shall  have the  right,  by  written  notice to KG, to
      terminate this Lease,  and KG shall thereupon  return the Security Deposit
      theretofore paid to Lessee, including interest thereon at the rate paid by
      KG's bank on such deposit.  If Lessor tenders  delivery of the Aircraft to
      Lessee on the Scheduled  Aircraft  Delivery Date, or prior to December 25,
      1997 if there is a delay,  and Lessee  refuses to accept  delivery for any
      reason other than the failure of Lessee's  conditions  precedent contained
      in Article 2.1.3 to have been met, KG may  terminate  this Lease and apply
      the Security Deposit  theretofore paid,  including interest thereon at the
      rate paid by KG's bank on such deposit against any actual damages suffered
      by it as a result  of  Lessee's  breach.  In any suit by  Lessee or KG for
      breach of the obligation to take or deliver the Aircraft,  as the case may
      be, such party's damages shall be limited to its actual damages  suffered,
      and both Lessee and KG waive the right to claim  consequential  or similar
      damages.

2.3   PLACE OF DELIVERY.

      The Aircraft shall be delivered to Lessee hereunder, at KG's option, at BF
      Goodrich/Tramco in Everett,  Washington,  or Colorado Springs, Colorado or
      at such alternate site as may be agreed between Lessee and KG.

2.4   DELIVERY FUEL.

      Fuel in the tanks of the  Aircraft  at  delivery  shall be recorded in the
      Lease Supplement.

2.5   INDEMNITY.

            i.    The Lessee shall  indemnify and hold harmless the  Indemnitees
                  from and  against  any and all  liabilities,  damages,  losses
                  (including costs and expenses  incidental  thereto) arising by
                  reason of death or injury to any  observer or any  employee of
                  the Lessee,  arising out of, or in any way connected  with any
                  demonstration  flight and inspection of the Aircraft conducted
                  pursuant to Exhibit "D" hereto.

            ii.   The Lessor shall  indemnify and hold  harmless  Lessee and its
                  shareholders,  affiliates,  directors,  officers,  agents  and
                  employees from and against any and all  liabilities,  damages,
                  losses  (including  costs  and  expenses  incidental  thereto)
                  arising  by reason of death or injury to any  observer  or any
                  employee of the Lessor or any  Indemnitee,  arising out of, or
                  in  any  way  connected  with  any  demonstration  flight  and
                  inspection of the Aircraft  conducted  pursuant to Exhibit "D"
                  hereto.

ARTICLE 3.  TERM AND RENT

3.1 TERM.

      The Aircraft shall be leased to Lessee hereunder for (i) a term commencing
      on the  Delivery  Date for the  Aircraft  and  ending  on the  Basic  Term
      Expiration Date (the "Basic Term"),  and (ii) at Lessee's  option,  for an
      additional period of up to two (2) years (the "Renewal Term"),  unless, in
      each case,  earlier  terminated as herein  provided.  If Lessee desires to
      exercise its option to extend the Term of this Lease for the Renewal Term,
      it shall give Beneficiary  irrevocable written notice of such election not
      less than 180 days prior to the last day of the Basic Term  specifying the
      length of the Renewal Term.  The Renewal Term shall commence at the end of
      the Basic Term and shall continue to the date specified in such notice. If
      the Lessee  exercises  its option to extend the Term,  the  parties  shall
      execute a Lease  Supplement  evidencing the extension of the Term prior to
      the end of the  Basic  Term.  The  date on which  the  Term of this  Lease
      expires or earlier terminates is herein called the "Expiration Date".

3.2   BASIC RENT.

      Lessee shall pay to Beneficiary  Basic Rent for the Aircraft  monthly,  in
      advance,  on the Delivery Date and on the same day as the Delivery Date in
      each month  thereafter  during the Basic Term (or, if there is no such day
      in such month,  on the last day of such month),  and monthly in advance on
      the first day of the  Renewal  Term,  if any,  and on the same day of each
      month thereafter during the Renewal Term.

3.3   SECURITY DEPOSIT.

      Beneficiary  has received from Lessee the sum of $[ ]* ([ ]* dollars) (the
      "Signing Deposit") in cash pursuant to the terms of the Letter of Intent.

      The  Lessee  shall pay to  Beneficiary  upon  execution  hereof $[ ]* (the
      "Second Deposit").

      In addition,  Lessee shall pay to  Beneficiary  (i) $[ ] * on September 1,
      1997 (the  "Third  Deposit")  and (ii) on the  Delivery  Date,  $[ ]* (the
      "Fourth Deposit").

      The Signing Deposit, the Second Deposit,  Third Deposit and Fourth Deposit
      aggregating $[ ]* are collectively  referred to as the "Security Deposit".
      Any cash portion of the Security  Deposit shall be held by the Beneficiary
      in a separate interest bearing account until such time as it is applied to
      Lessee's  obligations  as herein  provided or  returned  to Lessee.  On or
      before  the tenth day after the  Delivery  Date,  Lessee  shall  provide a
      letter of credit in accordance  with Article 17 for the Security  Deposit;
      provided  that if such Letter of Credit is provided on the Delivery  Date,
      the  Fourth  Deposit  shall not be  payable  by  Lessee in cash.  Upon the
      receipt of such letter of credit,  Beneficiary  shall  reimburse to Lessee
      the Security Deposit,  including interest thereon at the rate paid on such
      deposit by Beneficiary's bank.

      In the event that the Aircraft is not delivered to Lessee hereunder due to
      the  fault  of  Lessee,  Beneficiary  shall  have the  right to apply  the
      Security Deposit,  including  interest earned thereon,  against any actual
      damages suffered by it as a result of Lessee's  breach.  In the event that
      the Aircraft is delivered to Lessee hereunder,  the Security Deposit shall
      be  held by the  Beneficiary  as  security  for the  timely  and  faithful
      performance by Lessee of all of Lessee's obligations under this Lease, and
      Lessee hereby grants Beneficiary a security interest in all sums deposited
      under  this  Article  3.3.  Lessee  agrees  to  execute  and file with the
      appropriate  governmental  entities any and all  documents  necessary  and
      reasonably  requested  by Lessor to  evidence  and perfect  such  security
      assignment  in favor of  Beneficiary.  If an Event of  Default  shall have
      occurred  which is  continuing  in addition to all other rights Lessor and
      Beneficiary  shall have under the New York  Uniform  Commercial  Code as a
      secured party, Beneficiary may, but shall not be obligated to, use, apply,
      set-off or retain all or any  portion of the  Security  Deposit in payment
      for sums due by Lessee,  to compensate  Lessor or Beneficiary for any sums
      advanced  as a result of an Event of Default by Lessee or to apply  toward
      any losses or expenses  Lessor or Beneficiary  actually incurs as a result
      of such  Event of  Default.  If  Beneficiary  uses or  applies  all or any
      portion of such Security Deposit as provided above, such application shall
      not be deemed a cure of any Events of  Default,  and Lessee  shall  within
      five (5) days after written demand  therefor  deposit with  Beneficiary in
      cash an amount sufficient to restore the Security Deposit to the aggregate
      amount of such Security Deposit prior to Beneficiary's  use or application
      and Lessee's  doing so shall be deemed a cure of any such Event of Default
      but the  failure  of  Lessee to do so shall be a  material  breach of this
      Lease by Lessee. Provided that an Event of Default shall not have occurred
      and then be  continuing  and  provided  that  Lessee  shall  have paid all
      amounts  owing  hereunder,  any  cash  portion  of the  Security  Deposit,
      including  interest  earned  thereon,  and any  Letter of Credit  shall be
      returned  to  Lessee  at the end of the Term and  Lessee's  return  of the
      Aircraft in compliance with Article 13 hereof; provided that if the Letter
      of Credit or any cash portion of the  Security  Deposit is not returned to
      Lessee  because  an Event  of  Default  shall  have  occurred  and then be
      continuing or any amount owed by Lessee shall then be unpaid,  such Letter
      of Credit or cash portion of the Security  Deposit,  in each case,  to the
      extent not applied  hereunder shall be returned to Lessee at such time as,
      in the case of an Event of  Default,  such  Event of  Default is no longer
      continuing or Lessee's obligations under Article 15 have been satisfied in
      full,  as the case may be,  or,  in the case of an unpaid  amount  owed by
      Lessee, such unpaid amount has been satisfied in full.

3.4   SUPPLEMENTAL RENT.

      Lessee also agrees to pay to Beneficiary,  or the Person entitled  thereto
      hereunder,  any and all Supplemental Rent as the same shall become due and
      owing.  Lessee  will also pay to  Beneficiary  (or to the Person  entitled
      thereto), as Supplemental Rent, on demand,  interest at the Incentive Rate
      on any part of any Basic  Rent not paid when due and on any other  payment
      of Supplemental Rent not paid when due in accordance with the terms hereof
      for the period for which the same shall become due until the same shall be
      paid.

3.5   PAYMENTS ON BUSINESS DAY.

      If any date on which a payment of Rent  becomes  due and  payable is not a
      Business  Day,  the Rent  payment  otherwise  due and payable on such date
      shall be due and payable on the next Business Day (without  interest being
      payable as a result of such delay)  unless such  Business Day falls in the
      next  calendar  month,  in  which  case  such  amount  shall be due on the
      preceding Business Day.

3.6   PLACE OF PAYMENT.

      Notwithstanding  any other provision  hereof,  all payments of Rent (other
      than  indemnity  payments  in favor of a Person  other  than  Beneficiary)
      hereunder shall be payable in Dollars, in immediately  available funds, to

                  shall from time to time designate in writing.

3.7   PROHIBITION AGAINST SETOFF, COUNTERCLAIM, ETC.

      Lessee's obligation to pay Basic Rent and Security Deposit hereunder shall
      be  absolute  and   unconditional   and  shall  not  be  affected  by  any
      circumstances,    including,   without   limitation:   (i)   any   setoff,
      counterclaim,  recoupment,  defense or other right  which  Lessee may have
      against  Lessor,  Manufacturer,  Beneficiary,  or any other person for any
      reason  whatsoever,  (ii) any defect in the title, (iii) any defect in the
      airworthiness,  condition,  design,  operation, or fitness for use, or any
      damage to or loss or destruction, of the Equipment, or any interruption or
      cessation  in the use or  possession  thereof  by  Lessee  for any  reason
      whatsoever,  (iv) any insolvency,  bankruptcy,  reorganization  or similar
      proceedings by or against Lessee, or (v) any other circumstance, happening
      or event  whatsoever,  whether or not similar to any of the  foregoing and
      Lessee hereby waives,  to the extent  permitted by applicable law, any and
      all  rights  which it may now have or which may at any time  hereafter  be
      conferred  upon it by statute or otherwise to terminate,  cancel,  quit or
      surrender  this Lease or the Equipment,  or to any abatement,  suspension,
      deferment or reduction of Rent,  except in each case,  with respect to any
      period in which  Lessee's  use of the  Aircraft is  adversely  affected by
      Lessor's breach of the covenant set forth in Article 18.5 hereof.

                  necessary for the performance of its obligations hereunder and
                  is a "citizen  of the United  States"  (as  defined in section

                  commission,  board or other administrative governmental agency
                  against  Lessee  which may  reasonably  be  expected to have a
                  materially  adverse  effect  on  the  financial  condition  of
                  Lessee.

4.3   SUPPLIERS' WARRANTIES.

      Lessor hereby assigns to Lessee any and all  warranties,  representations,
      services,  policies  and  product  support  plans of  Manufacturer  or any
      subcontractor,  vendor or supplier of any Equipment or part hereof. Lessor
      authorizes  Lessee,  to the extent it may legally do so, to enforce in its
      own name such rights,  claims and interests as Lessor or  Beneficiary  may
      have under any warranty, representation, service policy or product support
      plan of  Manufacturer  or any  subcontractor,  vendor or  supplier  of any
      Equipment,  or part thereof, and to retain any benefit resulting therefrom
      to the extent the same  relates to  Lessee's  interests  in the  Equipment
      under this Lease and is not  compensation  in respect of work performed on
      the   Aircraft   prior   to  the   Delivery   Date;   provided,   however,
      notwithstanding  anything herein to the contrary,  if at any time an Event
      of Default shall have  occurred and be  continuing:  (i) at  Beneficiary's
      option,  the  authorization  hereby given to Lessee may be suspended until
      such time as no Event of Default which has occurred is then  continuing or
      terminated when the Lease is terminated and Beneficiary  shall be entitled
      to assert  and  enforce  such  rights,  claims and  interests,  whether as
      substitute  party plaintiff or otherwise,  and Lessee shall cooperate with
      Beneficiary to enforce such rights,  claims and interests and (ii) whether
      or  not   Beneficiary   exercises  its  option  under  clause  (i)  above,
      Beneficiary  shall be entitled to receive all proceeds  resulting from any
      such assertion or  enforcement  or rights,  claims or interests and, after
      deducting  from the  proceeds  thereof all costs and  expenses,  including
      attorneys'  fees that have been  incurred  by  Beneficiary  in  connection
      therewith,  Beneficiary may hold the remaining proceeds until Lessee shall
      have cured,  or  Beneficiary  in writing shall have waived,  all Events of
      Default, or at Beneficiary's  option, if there is in existence an Event of
      Default,  apply all or any such  remaining  proceeds to the payment of any
      obligation of Lessee at the time due  hereunder  and the balance,  if any,
      shall be payable to Lessee when Lessee  shall have cured,  or  Beneficiary
      shall have waived, all Events of Default. The assignment and authorization
      hereby given as to the Equipment  shall be effective so long,  and only so
      long, as such  Equipment  shall be subject to this Lease;  provided,  that
      Lessee may pursue  claims  after the end of the Term  against  maintenance
      providers  subject to the same  conditions set forth above in this Article
      4.3; and provided further that the assignment and  authorization  shall be
      permanent and free of all conditions with respect to any item of Equipment
      which  ceases to be  subject  to this  Lease  Agreement  as the  result of
      replacement or substitution in accordance with the terms hereof.

ARTICLE 5.  POSSESSION AND USE

5.1 POSSESSION.

      Subject  to the  right of  Lessee  to  deliver  possession  of any item of
      Equipment  to the  Manufacturer  thereof  for  testing  or  other  similar
      purposes or to any Authorized  Maintenance Performer for service,  repair,
      maintenance or overhaul work on such item of Equipment or any part thereof
      or for  alterations  or  modifications  in or  additions  to such  item of
      Equipment  to the extent  required or permitted by the terms of Articles 5
      and 6 hereof or to any  member of a pooling  arrangement  as  provided  in
      Article 6.2,  Lessee  shall not  sublease,  assign or  otherwise  transfer
      possession of any item of Equipment, or any part thereof, leased hereunder
      without the prior written consent of Beneficiary which consent will not be
      unreasonably  withheld,  but  may be  subject  to  such  conditions  as it
      reasonably  deems  necessary to protect its interests and the interests of
      Lessor; PROVIDED that a Wet Lease of 90 days or less (including all stated
      renewals)  may be entered  into without  Beneficiary's  consent so long as
      such Wet Lease is  expressly  subject  and  subordinate  to this Lease and
      Lessee provides a copy thereof to Beneficiary upon  commencement  thereof.
      This Lease and all or any part of Lessee's  rights  hereunder shall not be
      assigned or otherwise in any way  transferred  or  hypothecated  by Lessee
      without the prior written consent of Lessor, and any purported assignment,
      transfer  or  hypothecation  without the prior  written  consent of Lessor
      shall constitute an Event of Default hereunder and be void.

      Lessor  agrees for the  benefit of Lessee and for the benefit of any other
      holder of a security interest in any engine owned by Lessee, any lessor of
      any  engine  leased to Lessee  and any  conditional  vendor of any  engine
      purchased by Lessee  subject to a conditional  sale agreement or any other
      security  agreement,  that no interest  shall be created  hereunder in any
      engines so owned,  leased or  purchased  and that  neither  Lessor nor its
      successors or assigns will acquire or claim as against  Lessee or any such
      mortgagee,  lessor or  conditional  vendor or other  holder of a  security
      interest or any successor or assignee of any thereof, any right, title, or
      interest in such engine as a result of such engine being  installed on the
      Airframe;  PROVIDED  that such  agreement  of Lessor  shall not be for the
      benefit of any lessor or secured party of an airframe  leased to Lessee or
      purchased  by  Lessee  subject  to a  conditional  sale or other  security
      agreement  or for the benefit of any  mortgagee  or any other  holder of a
      security  interest  in an  airframe  owned by Lessee on which  Lessee then
      proposes to install an Engine,  unless such  lessor,  conditional  vendor,
      other  secured  party or mortgagee  party has  effectively  agreed  (which
      agreement  may be  contained  in such  lease,  conditional  sale or  other
      security  agreement or mortgage)  that  neither it nor its  successors  or
      assigns will acquire, as against Lessor or Beneficiary any right, title or
      interest in an Engine as a result of such Engine  being  installed on such
      airframe.

5.2   LAWFUL OPERATIONS; USE.

      Lessee will not permit any item of  Equipment  to be  maintained,  used or
      operated  in  violation  of any  law,  rule,  regulation  or  order of any
      government or  governmental  authority  having  jurisdiction  (domestic or
      foreign),  or in violation of any  airworthiness  certificate,  license or
      registration  relating  to any  item  of  Equipment  issued  by  any  such
      authority,  unless  (a)  Lessee  could not  reasonably  have known of such
      violation  in advance or  prevented  it  through  commercially  reasonable
      efforts or (b) the validity  thereof is being  contested in good faith and
      by appropriate  proceedings,  but only so long as, (i) such proceedings do
      not involve the likelihood of the sale,  forfeiture or loss of any item of
      Equipment or interest  therein,  and (ii) such  violation will not subject
      Lessor or Beneficiary to any criminal liability. Lessee shall base and use
      the Equipment solely in its commercial airline  operations,  and shall not
      use or permit the use of any item of  Equipment  for any purpose for which
      such item of Equipment is not designed and reasonably suitable.

      Lessee,  at its own cost and expense  shall,  subject to Articles  5.4 and
      6.3: (i) cause an  Authorized  Maintenance  Performer to service,  repair,
      maintain, overhaul and test each item of Equipment leased hereunder (A) so
      as to keep such item of Equipment in the same  condition as when delivered
      to Lessee hereunder (except as otherwise  permitted  hereunder),  ordinary
      wear and tear excepted, and in good operating condition, (B) so as to keep
      the  Aircraft  in  the  condition  as  may  be  necessary  to  enable  the
      airworthiness  certification  of such Aircraft by the FAA to be maintained
      in good standing (except for periods when such  airworthiness  certificate
      is not in effect due to the  performance of maintenance or overhaul of the
      Equipment  and  periods  when the  airworthiness  certificates  of 737-300
      aircraft  in general are  withdrawn  or  suspended  by the FAA) and (C) in
      strict compliance with Lessee's overhaul and maintenance  program approved
      by the FAA (ii) comply with all airworthiness directives issued by the FAA
      prior to the Expiration  Date having a mandatory  compliance date prior to

      other materials  required by the FAA to be maintained with respect to such
      Equipment;  (iv)  promptly  furnish to Lessor such  information  as may be
      required to enable Lessor and/or  Beneficiary to file any reports required
      to be filed by Lessor and/or  Beneficiary with any governmental  authority

                  the Delivery Date,  monthly in arrears on the 15th day of each

                  the final  payment shall be made on the date on which the Term
                  expires in respect of that part of the  calendar  month ending

            (a)   the Airframe heavy  maintenance (C-7) or equivalent check (but
                  excluding rotable repairs) and landing gear overhauls; and

            (b)   two such accounts for each Engine (which expression shall, for
                  this purpose,  not extend to any rotable  components or Engine
                  components  forming  part of a  quick  engine  change  ("QEC")
                  assembly,  nose cowl and  thrust  reverser)  one for  off-wing
                  scheduled  maintenance  and the  accomplishment  of comparable
                  work performed during  unscheduled shop visits,  and the other
                  for  Engine  life  limited  part  ("LLP")   replacement,   but
                  excluding,  in each case,  QEC repair,  foreign object damage,
                  operational misuse and Lessee's negligence.

                  Auxiliary  power  unit  maintenance  is  not  covered  by  the
                  Maintenance  Reserves.  The five Maintenance  Reserve accounts
                  are  to  be  maintained  by  the   Beneficiary   for  its  own
                  administrative convenience.  Maintenance Reserves shall accrue
                  interest  at the rate  offered by  Beneficiary's  bank for one
                  month  deposits  from  time  to  time.   Interest  accrued  on
                  Maintenance  Reserves shall be credited  monthly and available
                  for the payment of Eligible  Claims.  The amount available for
                  the  payment of  Eligible  Claims  shall be the amount paid by
                  Lessee  with  respect  to  the  relevant  Maintenance  Reserve
                  account plus interest accrued thereon.

         iv.      RATES.

            The Hourly Rate and per Cycle rate payable  shall be as set forth on
            Exhibit "I" hereto:

          v.      ADJUSTMENT OF HOURLY RATES.

            The  Hourly  Rates for Engine  off-wing  scheduled  maintenance  are
            computed on the basis of 1.7 Flight  Hours per  Aircraft  Cycle.  On
            each  anniversary  of the Delivery  Date during the Term,  the total
            Engine  Flight  Hours for each  Engine  recorded  in  respect of the
            previous  twelve  months shall be compared with the Cycles flown for
            such Engine and,  the Hourly  Rate for such Engine  applicable  with
            respect to Maintenance  Reserve  payments due from Lessee after such
            adjustment  and  prior to the  next  annual  adjustment  shall be as
            provided  in  Exhibit C hereof for such  recomputed  ratio of Flight
            Hours to Cycles.

         vi.      APPLICATION OF MAINTENANCE RESERVES.

            (a)   Beneficiary's  obligation to reimburse Lessee for any Eligible
                  Claims  referred to in Article 5.4 (i)/(iii) is subject to the
                  conditions  that:  (i)  before  any work with  respect to such
                  Eligible Claim is performed,  Lessee shall notify  Beneficiary
                  of the  proposed  date of the check or shop visit and the work
                  to be performed (to the extent then known to Lessee); and (ii)
                  following completion of the work with respect to such Eligible
                  Claim,  the  Lessee  shall  present to  Lessor's  Tech Rep all
                  worksheets,  invoices,  vouchers  and/or receipts with respect
                  thereto which are reasonably necessary to establish the amount
                  of such Eligible Claim;

            (b)   Within  20  days  after   Lessor's   Tech  Rep  receives  such
                  documentation, Beneficiary will pay the amount of the Eligible
                  Claim to Lessee by making a drawdown against the amount in the
                  applicable  Maintenance Reserve account. In the event that the
                  amount of such Eligible Claim exceeds the amount available for
                  reimbursement thereof pursuant to the terms hereof, the Lessee
                  shall be responsible for the payment of such excess.

                  The cost of  replacement  of LLPs at the first  scheduled shop
                  visit  for  each  Engine  after  the  Delivery  Date  shall be
                  allocated as follows:  (i) Beneficiary's  share of the cost of
                  any LLP  shall  be an  amount  equal  to the  cost of the LLPs
                  replaced during such shop visit times a fraction the numerator
                  of which is the number of Cycles  accumulated on the LLP prior
                  to the  Delivery  Date and the  denominator  is the  number of
                  Cycles  accumulated  on the LLP since it was installed in such
                  Engine and (ii) the  Lessee's  share  shall be the cost of the
                  LLP minus the  Beneficiary's  share.  The Lessee may draw down
                  from respective LLP accounts of the  Maintenance  Reserves for
                  its share of the cost of such first scheduled shop visit,  but
                  if the Lessee's  share of such cost exceeds the amount in such
                  account Lessee will pay the difference.  Beneficiary  will pay
                  its  share  at the time  Lessee  draws  from  the  Maintenance
                  Reserves.

                  Notwithstanding  anything  else to the  contrary  contained in
                  this Lease,  in no event shall the Beneficiary be obligated to
                  pay any amounts with respect to Eligible  Claims  (whether out
                  of the applicable  reserve account or otherwise) so long as an
                  Event under Article  14.1(a) or an Event of Default shall have
                  occurred and be continuing.

            (c)   Any repair or overhaul  work that is performed by Lessee shall
                  be billed at Lessee's actual,  fully-burdened  labor cost (not
                  to exceed 130% of direct  cost) and without any mark-up in the
                  cost of  materials.  If work is done by a  company  affiliated
                  with  Lessee,   charges  made  by  such  affiliate   shall  be
                  reasonable market rates for such maintenance work.

            (d)   For the avoidance of doubt, Maintenance Reserves in respect of
                  the  Engines  may be  used  for (i) the  cost of a  repair  or
                  overhaul of an Engine which would  otherwise  be  reimbursable
                  from the  Maintenance  Reserves and which is undertaken at the
                  same  time as  other  remedial  work  which is  excluded  from
                  reimbursement  (for example repair of a foreign object damage)
                  subject to the requirements of Article 5.4(vi)(a), and (ii) to
                  pay for the cost of bringing any Engine into  compliance  with
                  the return conditions hereof.

            (e)   NEITHER LESSOR NOR  BENEFICIARY  SHALL HAVE ANY DUTY TO LESSEE
                  TO  DETERMINE  WHETHER ANY ITEM OF EQUIPMENT IS REQUIRED TO BE
                  OVERHAULED  OR  MAINTAINED,  OR  TO  OBSERVE  OR  INSPECT  THE
                  OVERHAUL OR MAINTENANCE OF ANY ITEM OF EQUIPMENT,  AND NEITHER
                  LESSOR NOR BENEFICIARY SHALL INCUR ANY LIABILITY OR OBLIGATION
                  TO  LESSEE BY REASON OF THE  FAILURE  OF ANY  EQUIPMENT  TO BE
                  PROPERLY  OVERHAULED OR MAINTAINED  AFTER THE DELIVERY DATE OR
                  BY REASON OF LESSOR'S OR BENEFICIARY'S  ELECTION TO OBSERVE OR
                  INSPECT  OR  NOT  TO  OBSERVE  OR  INSPECT  ANY   OVERHAUL  OR
                  MAINTENANCE OF ANY ITEM OF EQUIPMENT.

        vii.      Lessee  acknowledges that the Maintenance Reserve payments for
                  an item of Equipment shall become the unencumbered property of
                  Beneficiary upon payment thereof by Lessee, free of any claims
                  or rights  thereto  by  Lessee  and any  Maintenance  Reserves
                  remaining at the end of the Term shall  belong to  Beneficiary
                  provided  that, if an Event of Loss occurs with respect to the
                  Aircraft  or  the  Airframe,  any  Maintenance  Reserves  then
                  remaining  shall  be  paid  to  Lessee  upon  satisfaction  of
                  Lessee's  obligation  under  Article 10 to pay, or cause to be
                  paid,  the  Agreed  Value  and  all  other  amounts  then  due
                  hereunder,  to Beneficiary.  To the extent Maintenance Reserve
                  payments  are  used  to pay for the  cost of any  overhaul  or
                  maintenance  contemplated  in this Article 5.4, any recoveries
                  from Manufacturer or any subcontractor,  vendor or supplier in
                  respect  thereof  shall  be  for  the  exclusive   benefit  of
                  Beneficiary.

                  On the 15th day of each month, Lessee shall notify Beneficiary
                  and Lessor's Tech Rep of the number of Flight Hours and Cycles
                  which have been  accumulated on the Airframe and the number of
                  Flight  Hours and Cycles  that have been  accumulated  on each
                  Engine during the preceding  calendar month,  and Lessee shall
                  provide Beneficiary and Lessor's Tech Rep with such supporting
                  information and  documentation as Beneficiary or Lessor's Tech
                  Rep may from time to time reasonably request.

5.5   REGISTRATION AND INSIGNIA.

      Lessee agrees that it will at all times at Beneficiary's expense cooperate
      with Lessor and  Beneficiary in maintaining  the U.S.  registration of the
      Aircraft.  Upon delivery of the Aircraft,  Lessee shall fasten or cause to
      be fastened and maintained in the cockpit of the Aircraft  adjacent to the
      airworthiness  certificate  for  the  Aircraft  and on each  Engine,  in a
      prominent location,  metal nameplates at least three inches by five inches
      bearing the following legend:

                  "First Security Bank, National Association
                            Owner Trustee and Lessor"

      Except as above  provided,  Lessee  will not allow the name of any person,
      firm or  corporation  to be  placed  on the  Airframe  or any  Engine as a
      designation that might be interpreted as a claim of ownership or to a Lien
      thereon;  provided,  however,  Lessee may cause the Airframe to be painted
      with its name and in its livery during the Term hereof.

ARTICLE 6.  REPLACEMENT AND POOLING OF PARTS; ALTERATIONS; MODIFICATIONS AND
ADDITION

6.1 REPLACEMENT OF PARTS.

      Lessee,  at its own cost and expense  (but  subject to Article 5.4 and 6.3
      hereof),  will replace as promptly as practicable all Parts which may from
      time  to  time  become  worn  out,  lost,   stolen,   destroyed,   seized,
      confiscated,  damaged beyond repair or permanently rendered unfit for use.
      All  replacement  Parts  shall be free and clear of all Liens  other  than
      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.

      All Parts at any time removed from the Airframe or any Engine shall remain
      the property of Lessor,  no matter where located,  until such time as such
      Parts shall be replaced by parts owned or paid for by Lessee (or  provided
      by a  Manufacturer  or service  provider  pursuant to a warranty,  service
      contract  or  similar  agreement)  and  incorporated  or  installed  in or
      attached to such  Airframe or Engine in compliance  with the  requirements
      for  replacement   Parts  specified  above.   Immediately  upon  any  such
      replacement Part becoming  incorporated or installed in or attached to the
      Airframe or an Engine as above provided, without further act: (i) title to
      such  replacement   Part  shall  thereupon  vest  in  Lessor,   (ii)  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 Part  originally  incorporated  or  installed in or
      attached to such  Airframe or Engine,  and (iii) title to the removed Part
      shall thereupon vest in Lessee, free and clear of all Lessor Liens and all
      rights of  Lessor  and  Beneficiary,  and shall no longer be deemed a Part
      hereunder.
6.2   POOLING OF ENGINES AND PARTS.

      (i) The Lessee may subject the  Engines to normal  interchange  or pooling
      agreements with the Manufacturer or responsible  scheduled  commercial air
      carriers  customary in the airline  industry and entered into by Lessee in
      the ordinary  course of business so long as (a) such Engine is required to
      be returned to Lessee  within two (2) months,  (b) no transfer of title to
      the Engine  occurs (or if such transfer of title occurs it will be treated
      as an Event of Loss),  (c) the other  terms of this Lease  continue  to be
      observed with respect to the Engines and (d) Lessee  continues to be fully
      responsible  to Lessor for the  performance of all  obligations  hereunder
      relating to such Engines

      (ii) Any Part  removed  from the  Airframe  or an  Engine as  provided  in
      Article 6.1 may be  subjected  by Lessee to a normal  pooling  arrangement
      customary in the airline  industry  entered into in the ordinary course of
      Lessee's business,  provided the part replacing such removed Part shall be
      incorporated  or  installed  in or attached  to the  Airframe or Engine in
      accordance  with Article 6.1 as promptly as possible  after the removal of
      such removed Part. In addition,  any replacement part when incorporated or
      installed in or attached to the Airframe or any Engine in accordance  with
      Article  6.1 may be  owned  by an air  carrier  subject  to such a  normal
      pooling  arrangement,   provided  Lessee,  at  its  expense,  as  promptly
      thereafter as possible either (a) causes title to such replacement part to
      vest in Lessor in accordance  with Article 6.1 by Lessee  acquiring  title
      thereto for the benefit of, and  transferring  such title to,  Lessor free
      and clear of all Liens other than  Permitted  Liens,  or (b) replaces such
      replacement  part by  incorporating  or  installing in or attaching to the
      Airframe  or Engine a further  replacement  part owned by Lessee  free and
      clear of all Liens other than Permitted  Liens,  and causing title to such
      further replacement part to vest in Lessor in accordance with Article 6.1

6.3   ALTERATIONS, MODIFICATIONS AND ADDITIONS.

      Subject only to the last paragraph of this Article 6.3, Lessee, at its own
      expense, shall make such alterations and modifications in and additions to
      the  Equipment  as may be  required  from time to time by the FAA or other
      governmental authority having jurisdiction, unless the validity thereof is
      being contested in good faith and by appropriate  proceedings (but only so
      long as (i)  such  proceedings  do not  involve  the  likelihood  of sale,
      forfeiture or loss of any Equipment, or any interest therein and (ii) such
      proceedings   do  not  subject  Lessor  or  Beneficiary  to  any  criminal
      liability).

      In addition,  Lessee, at its own expense,  may from time to time make such
      alterations and  modifications  in and additions to each item of Equipment
      as Lessee  may deem  desirable  in the  proper  conduct  of its  business,
      provided that no such alteration,  modification or addition diminishes the
      value or utility of such item of  Equipment  or impairs the  condition  or
      airworthiness   thereof   below  the   value,   utility,   condition   and
      airworthiness  thereof immediately prior to such alteration,  modification
      or addition,  assuming  such item of  Equipment  was then of the value and
      utility and in the condition and  airworthiness  required to be maintained
      by the terms of this  Lease;  provided  further  that no such  alteration,
      modification,  or addition with an estimated cost in excess of $[ ]* shall
      be made (other than an alteration,  modification,  or addition required to
      be made pursuant to the first  sentence of this Article 6.3 or as provided
      in Article  6.4) without the prior  written  consent of  Beneficiary.  Any
      permitted modification shall be made in accordance with, and in compliance
      with,  FAA-approved  modification  documentation,  any  FAA  certification
      issues  shall  have been  addressed  to  Lessor's  Tech  Rep's  reasonable
      satisfaction,  and copies of all such  documentation  will be  supplied to
      Lessor's  Tech Rep.  Title to all Parts  incorporated  or  installed in or
      attached  or  added  to any  item  of  Equipment  as the  result  of  such
      alteration,  modification or addition shall,  without further act, vest in
      Lessor; provided,  however, that so long as no Event under Article 14.1(a)
      or Event of Default  shall have  occurred and be  continuing,  at any time
      during the Term in effect for an item of Equipment,  Lessee may remove any
      Part  from  such  item of  Equipment,  provided  that (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  item of
      Equipment  at the time of the  delivery  thereof  hereunder or any Part in
      replacement of, or substitution  for, any such Part, (ii) such Part is not
      required to be  incorporated  or installed in or attached or added to such
      item of  Equipment  pursuant  to the terms of the first  sentence  of this
      Article  6.3,  and  (iii)  such  Part can be  removed  from  such  item of
      Equipment   without  causing  any  material  damage  thereto  and  without
      diminishing or impairing the value,  utility,  condition or  airworthiness
      which  such  item of  Equipment  would  have  had at such  time  had  such
      alteration,  modification  or addition not  occurred.  Upon the removal by
      Lessee of any such Part as provided  above,  title thereto shall,  without
      further act,  vest in Lessee free of Lessor Liens and all rights of Lessor
      and  Beneficiary and such Part shall no longer be deemed a Part hereunder.
      Any Part not  removed by Lessee as above  provided  prior to the return of
      the item of  Equipment  to Lessor  hereunder  shall remain the property of
      Lessor.

      Neither  Lessor nor  Beneficiary  shall bear any liability or cost for any
      alteration,  modification, addition, or for any grounding or suspension of
      certification  of any item of Equipment  or for loss of revenue;  provided
      always,  however,  that in the event that the cost (material and labor) of
      (i) compliance with any  airworthiness  directive ("AD") issued by the FAA
      during the Term which  requires  terminating  action  during the Term,  or
      within twelve months after the Expiration Date or (ii) compliance with any
      regulatory  requirement  necessary  for the Aircraft to meet FAR Part 121,
      exceeds $[ ]*,  Lessee  shall pay the first $[ ]* and the  excess  will be
      shared between Lessee and Beneficiary as follows.  The Beneficiary's share
      shall be calculated by application of the following formula:

            [1 - (N - M)/(300 - (X + M))] x (C - $[     ]*)

            where,

            "N"   equals 120;

            "M"   equals  the  number  of whole  months  of the Term  that  have
                  elapsed  as of the date of actual  compliance  with such AD or
                  regulatory change;

            "X"   equals the number of whole months from the date of
                  manufacture of the Aircraft to the Delivery Date; and

            "C"   equals the cost of compliance with such AD or regulatory
                  change.

      The Lessee's share will be the balance. If during any calendar year Lessee
      is  required  to  comply  with more  than ten (10) ADs  and/or  regulatory
      changes,  and the cost to Lessee of such compliance  exceeds $[ ]* in such
      calendar year, then Beneficiary will contribute to the eleventh (11th) and
      any  subsequent  AD or  regulatory  change  during such  calendar  year in
      accordance with the above formula without deducting $[ ]* from "C."

Lessee shall give Beneficiary  prior written notice of any such AD or FAR before
commencing any alteration, modification or addition of the Aircraft with respect
thereto. Any work that is performed by Lessee with respect to any such AD or FAR
shall be billed at Lessee's  actual fully  burdened  labor cost (which shall not
exceed 130% of direct  cost) and  without any mark-up in the cost of  materials.
Lessee shall provide to Lessor's Tech Rep all original invoices, work sheets and
or receipts  reasonably  necessary to establish costs for which reimbursement is
sought,  and Beneficiary  shall  reimburse  Lessee for its share of any eligible
costs within 20 days of receipt of such documentation.

6.4   CERTAIN MATTERS REGARDING SEVERABLE EQUIPMENT.

      Lessee  may at any time and from time to time,  so long as no Event  under
      Article  14.1(a)  or Event of  Default  has  occurred  and is  continuing,
      install  on the  Airframe,  subject  to  the  requirements  of the  second
      paragraph of Article 6.3 above,  Severable  Equipment that is (i) owned by
      another Person and leased to Lessee, (ii) sold to Lessee by another Person
      subject  to  a  conditional  sale  contract  or  other  retained  security
      interest, (iii) leased to Lessee pursuant to a lease which is subject to a
      security  interest  in favor of another  Person or (iv)  installed  on the
      Aircraft subject to a license granted to Lessee by another Person,  and in
      any such case (A) Lessor  will not  acquire or claim,  as against any such
      other Person, any right, title or interest in any such Severable Equipment
      solely as a result of its  installation on the Airframe,  (B) Lessee shall
      notify such Person of Lessor's and  Beneficiary's  respective  interest in
      the Aircraft,  and (C) Lessee shall  procure  that,  and such Person shall
      confirm in writing to Lessor  that,  upon the  occurrence  of any  default
      under the applicable lease, conditional sale agreement, security agreement
      or license,  such Person  shall not be entitled to detain the  Aircraft or
      repossess such Severable  Equipment  unless it shall,  in connection  with
      such  repossession,  restore the  Aircraft to the  condition it would have
      been in had the installation of such Severable Equipment not occurred.

ARTICLE 7.  INSPECTION; FINANCIAL INFORMATION; RECORD

7.1 INFORMATION AND INSPECTION.

      During  the  Term of this  Lease,  Lessee  shall  furnish  to  Lessor  and
      Beneficiary   such   additional   information   concerning  the  location,
      condition,  modification status,  compliance with the maintenance program,
      installed equipment, use and operation of each item of Equipment as Lessor
      or Beneficiary may reasonably request,  and Lessee shall permit any person
      designated by Lessor or Beneficiary in writing (other than a person who is
      not eligible to be  designated  as Lessor's Tech Rep unless such person is
      inspecting  the  Aircraft in  connection  with  Beneficiary's  remarketing
      efforts  during  the  final  year of the  Lease or  during  the  continued
      existence  of an Event of  Default),  at  Beneficiary's  expense (or if an
      Event under 14.1(a) or an Event of Default has occurred and is continuing,
      at Lessee's  expense),  to inspect each item of Equipment,  its condition,
      use, and operation and the Records maintained in connection therewith, and
      to meet with the  principal  officers  of Lessee,  all at such  reasonable
      times and as often as Lessor or Beneficiary may reasonably request so that
      such  inspections  and  meetings do not  unreasonably  interfere  with the
      operation or maintenance of the Aircraft or the conduct of the business of
      Lessee.  Any such inspection of the Aircraft shall be a visual walk-around
      inspection which shall not include opening any panels, bays or the like or
      any  disassembly  or  removal  of  components  which are not then  opened,
      disassembled  or  removed  in the course of  Lessee's  maintenance  of the
      Aircraft at the time of such inspection. Lessor and Beneficiary shall have
      no duty to make any such  inspection  and shall not incur any liability or
      obligation by reason of not making such inspection.

7.2   FINANCIAL INFORMATION.

      Lessee also agrees to furnish  Lessor and  Beneficiary  with the following
      during the Term of this Lease;

          i.      within  one  hundred  twenty  (120) days after the end of each
                  fiscal year of Lessee (or such longer period of time as agreed
                  by Lessor  and  Lessee),  a balance  sheet and  statements  of
                  income and  retained  earnings  of Lessee,  as of the close of
                  such  fiscal  year,  setting  forth  in  comparative  form the
                  figures  for  the  previous   fiscal  year,  as  certified  by
                  independent  public  accountants,  including their certificate
                  and accompanying comments;

         ii.      promptly upon their becoming available,  copies of all regular
                  and periodic  reports filed by Lessee with the  Securities and
                  Exchange  Commission and the principal  securities exchange on
                  which the common stock of Lessee is listed; and

        iii.      such other  information  concerning  Lessee as Beneficiary may
                  from time to time reasonably request.

7.3   REPORTS OF AIRCRAFT USE.

      Without limiting Lessee's other obligations under this Lease, Lessee shall
      also  provide  in  a  timely  manner  Beneficiary  with  details  of:  (i)
      replacement of Engines, auxiliary power unit, avionics,  undercarriage and
      control  surface  changes  (and the reason for such  changes),  (ii) major
      repairs in excess of the  Damage  Notification  Threshold,  modifications,
      alterations and additions to an item of Equipment, (iii) service bulletins
      and airworthiness  directives  applicable to and accomplished with respect
      to any item of  Equipment,  (iv)  copies  of any  repair  or  modification
      drawings  and  approvals  or data  covering  any  unique  or  non-standard
      modifications  to an item of Equipment,  in each case with respect to such
      preceding  calendar  month;  and  (v)  within  30  days of the end of each
      calendar  year of the Term  copies of  Lessee's  work  papers  prepared to
      apportion  Lessee's usage of the Aircraft among the various states. In the
      case of (i), (ii), (iii) and (iv), the data shall be provided on a monthly
      basis.

ARTICLE 8.  INDEMNIFICATION BY LESSEE.

8.1   GENERAL INDEMNITY.

      Lessee  agrees  to pay,  and on  demand to  indemnify  and hold  harmless,
      Lessor,  Beneficiary and their respective successors,  assigns, agents and
      servants,  from  and  against  any  and  all  claims,   damages,   losses,
      liabilities  (including,  but not limited to, any claim or  liability  for
      strict  liability in tort or  otherwise,  including,  without  limitation,
      liability  arising under any  applicable  environment,  noise or pollution
      control statute, rule or regulation), demands, suits, judgments, causes of
      action and all legal  proceedings,  whether civil or criminal,  penalties,
      fines  and  other  sanctions,  and any  costs  and  expenses  incurred  in
      connection  therewith,  including  attorney's fees, which may result from,
      relate to or arise out of the condition, lease, sub-lease, possession, use
      or  operation  of any item of  Equipment,  or which  may be  caused by any
      defect in any item of  Equipment,  latent or  otherwise,  arising from the
      material or any article  used  therein or from the design,  testing or use
      thereof or from any  maintenance,  service,  repair,  overhaul  or testing
      thereof,  (any such basis for an indemnity set forth above being  referred
      to herein as a "Loss");  provided,  however, that in all cases referred to
      in this Article 8.1,  excluding  any Loss to the extent that such Loss (i)
      is the  subject  matter  of  another  indemnity  provision  of this  Lease
      Agreement  or  consists  of  a  cost  or  expense  imposed  on  Lessor  or
      Beneficiary by the terms hereof or is incurred by Lessor or Beneficiary in
      performing its obligations to Lessee hereunder, (ii) arises as a result of
      the wilful misconduct or gross negligence of any Indemnitee,  (iii) arises
      as a  result  of  Lessor  Taxes  or a  Lessor  Lien or any  breach  by any
      Indemnitee of its representations or obligations hereunder, (iv) is caused
      by  acts,  omissions  or  events  which  occur  following  the  return  of
      possession  of the  Aircraft  to Lessor or its  designee at a time when no
      Event or Default shall have occurred and then be continuing,  (v) consists
      of costs,  fees or  expenses  related to the  negotiation  preparation  or
      execution of the Letter of Intent or the Lease Agreement, (vi) consists of
      costs,  fees or  expenses  arising out of the  acquisition  or transfer by
      Lessor or any  Indemnitee  of any  interest in the  Aircraft or this Lease
      Agreement  except any such  transfer in  connection  with the  exercise of
      remedies hereunder in accordance with the terms of Article 15 hereof after
      the occurrence of an Event of Default or as a result of a replacement of a
      Part or an Engine pursuant to Article 6.1 or 9.2 hereof,  (vii) arises out
      of or results  from acts of any  Indemnitee  prior to the  Delivery  Date,
      (viii)  is one  with  respect  to  which  the  Indemnitee  has a right  to
      participate in a proceeding  with respect to such Loss, if such Indemnitee
      refuses to implead,  to the extent  reasonable and practicable,  any party
      whom Lessee believes is ultimately responsible with respect to such Losses
      or to assert, to the extent  reasonable and practicable,  any cross-Losses
      Lessee  deems  appropriate  where it in not  possible for Lessee to assert
      such rights itself,  (ix) relates to the  performance by any Indemnitee of
      its  obligations  under this Lease Agreement or arising out of any default
      under  any  financing  of any  item of  Equipment  that is not an Event of
      Default hereunder,  (x) arises, out of any change in any agreement related
      to the financing of the Aircraft,  any Engine or any Part thereof,  unless
      Lessee has expressly  agreed to undertake  such  obligations,  and/or (xi)
      relates to the costs, fees and any other  out-of-pocket  expenses incurred
      in connection with the establishment,  maintenance or restructuring of the
      financing or refinancing of the Aircraft or any  Indemnitee's  interest in
      the trust estate  established under the Trust Agreement or the creation or
      maintenance  of such trust estate or to any action or dispute  between the
      parties to any  agreement  with  respect to the  financing  of any Item of
      Equipment not resulting from the occurrence and continuance of an Event of
      Default hereunder.

      Notwithstanding  anything to the  contrary  contained in this Article 8.1,
      the indemnification  provided for herein shall not include indemnification
      of any person in such person's  capacity as designer,  manufacturer  of or
      maintenance performer for the Aircraft, any Engine or any Part.

      The following  shall apply to all claims for indemnity  under this Article
      8.1: an Indemnitee  shall promptly  notify Lessee of any claim as to which
      indemnification   is  sought  upon  obtaining  actual  knowledge  thereof;
      provided that the failure to provide such notice shall not release  Lessee
      from any of its  obligations  to  indemnity  hereunder  or from any  other
      obligation that the Lessee may have to such Indemnitee at law or in equity
      (provided  that Lessee's  obligations to indemnify  hereunder  shall in no
      event be increased due to such a failure to provide  notice and no payment
      by Lessee to such  Indemnitee  shall be deemed to  constitute  a waiver or
      release  of any  right  or  remedy  which  Lessee  may have  against  such
      Indemnitee for any damages as a result of such failure to provide notice).
      Subject to the rights of insurers under  policies of insurance  maintained
      by Lessee,  Lessee shall investigate,  and provided no Event under Article
      14.1(a),  (b), (f) or (g) of the Lease or Event of Default under the Lease
      shall  have  occurred  and be  continuing,  at its sole cost and  expense,
      defend  or  compromise  (other  than with  respect  to a  compromise  of a
      non-monetary  claim the  compromise of which shall  adversely  affect such
      Indemnitee,)  any claim for which  indemnification  is sought  under  this
      Article 8.1, and the Indemnitee shall cooperate, at Lessee's expense, with
      all reasonable requests of Lessee in connection  therewith;  provided that
      if such an Event or Event of Default has occurred and is  continuing,  the
      applicable  Indemnitee  shall  in good  faith  contest  such  claim at the
      request and expense of Lessee;  and provided further that such proceedings
      do not  involve  the  likelihood  of loss or  forfeiture  of  title to the
      Aircraft  (unless  Lessee  shall  have  posted  a bond or  other  security
      reasonably satisfactory to such Indemnitee in respect of such risk) or any
      material risk of any civil or criminal  penalty being assessed against any
      Indemnified  Person.  Where  Lessee  or the  insurers  under a  policy  of
      insurance maintained by Lessee undertake the defense of an Indemnitee with
      respect  to a  claim,  no  additional  legal  fees  or  expenses  of  such
      Indemnitee  in  connection  with  the  defense  of  such  claim  shall  be
      indemnified  hereunder  unless such fees or expenses  were incurred at the
      written request of Lessee or such insurers;  provided, however, that if in
      the written opinion of counsel to such Indemnitee a potential material, or
      an actual,  conflict of interest  exists  where is it  advisable  for such
      Indemnitee to be represented by separate counsel, then the reasonable fees
      and expenses of such separate counsel shall be borne by Lessee. Subject to
      the requirements of any policy of insurance, an Indemnitee may participate
      at its  own  expense  in any  judicial  proceeding  controlled  by  Lessee
      pursuant  to  the  preceding   provisions;   provided  that  such  party's
      participation  does  not,  in  the  opinion  of  the  independent  counsel
      appointed by Lessee or its insurers to conduct such proceedings, interfere
      with such  control  (except in the case  specified  in the  proviso to the
      third  sentence  of this  paragraph;  and  such  participation  shall  not
      constitute a waiver of the  indemnification  provided in this Article 8.1.
      Notwithstanding  anything to the contrary  contained herein,  Lessee shall
      not under any  circumstances  be liable for the fees and  expenses of more
      than one counsel for all  Indemnitee  except in the case  specified in the
      proviso to the third sentence of this paragraph.

      No Indemnitee shall enter into a settlement or other compromise or consent
      to a judgment with respect to any Loss without the prior  written  consent
      of Lessee,  which consent shall not be  unreasonably  withheld or delayed,
      unless such Indemnitee waives its rights with respect to such Losses under
      this Article 8.1;  provided  that the payment of an amount to which a Loss
      relates  when  legally  compelled  to  do  so by a  Government  Entity  of
      competent  jurisdiction  after which a request for a refund of such amount
      is diligently  pursued by  appropriate  procedures in accordance  with the
      terms of this Article 8.1 will not be considered a settlement,  compromise
      or consent to judgment  requiring Lessee's prior consent or resulting in a
      waiver of such Indemnitee's rights of indemnification with respect to such
      amount.   Except  as  otherwise  provided  in  the  immediately  preceding
      sentence,  the entering into any such  settlement or compromise or consent
      without  Lessee's prior written consent shall  constitute a waiver by such
      Indemnitee  of all its rights of  indemnification  hereunder in respect of
      such matter.

      To the extent that a claim  indemnified  by Lessee under Article 8.1 is in
      fact paid in full by Lessee  and/or an insurer under a policy of insurance
      maintained  by Lessee,  Lessee  and/or such  insurer,  as the case may be,
      shall be  subrogated  to rights and  remedies of the  Indemnitee  on whose
      behalf such claim was paid (other  than  rights of such  Indemnitee  under
      insurance  policies  maintained  at its own  expense)  with respect to the
      transaction or event giving rise to such claim.  So long as no Event under
      Article 14.1(a), (b), (f) or (g) or Event of Default under the Lease shall
      have occurred and be continuing,  should an Indemnitee receive any payment
      from any person  other than Lessee or its insurers and except for payments
      received under insurance  policies  maintained by an Indemnitee at its own
      expense,  in whole or in part,  with respect to any claim  already paid by
      Lessee or its insurers  hereunder,  such Indemnitee shall promptly pay the
      amount so  received  (but not an amount in excess of the amount  Lessee or
      any of its insurers has paid in respect of such claim) over to Lessee.

      Notwithstanding  anything to the  contrary  contained in this Article 8.1,
      the  indemnification  provided for in this Article 8.1 shall only apply to
      matters which occur or fail to occur  subsequent to the  acceptance of the
      Aircraft  hereunder  and prior to the  Expiration  Date and  return of the
      Equipment pursuant to the terms hereof. The indemnities  contained in this
      Article  8.1 shall  expire  and be of no  further  force and  effect  with
      respect  to any  claim  or  other  circumstance  set  forth  in the  first
      paragraph of this Article 8.1 notice of which shall not have been given to
      Lessee in writing (referring expressly to this Article 8.1) on or prior to
      the second anniversary of the Expiration Date.

8.2         GENERAL TAX INDEMNITY.

      (i)   Beneficiary  represents and warrants that, on the date hereof it is,
            and on the day prior to the Delivery Date it will be, eligible for a
            withholding  rate of zero under the double  taxation  treaty then in
            effect  between the United States and Ireland,  and that payments of
            Rent may be made directly to it without withholding on account of US
            income taxes by Lessee.

      (ii)  Lessee agrees that,  if as the result of a change in the  U.S.-Irish
            Tax Treaty occurring after the Delivery Date ("Irish Treaty Change")
            withholding  of U.S.  income  tax is  required  with  respect to any
            payment  of Rent  hereunder,  each  payment  of Rent due  after  the
            effective date of such change shall be free of all  withholdings and
            deductions for or on account of taxes,  duties and any other charges
            of any  nature  whatsoever,  present  or  future,  unless  Lessee is
            required  by  operation  of law or  otherwise  to withhold or deduct
            amounts for or on account of any of the same, in which event, Lessee
            will pay such  additional  amounts as will  result in the receipt by
            Beneficiary  on the due date for  payment  thereof of the sums which
            would  otherwise have been receivable on such date had there been no
            such withholding or deduction; Lessor and Beneficiary shall file and
            provide to Lessee such returns, statements or other documentation as
            shall enable it to claim any reduced rate of tax withholding and any
            exemption from tax  withholding  with respect to any taxes,  fees or
            other  charges to which the terms of Article  8.2 hereof  apply,  in
            each case, to the extent properly  available under applicable law or
            any applicable  treaty without  subjecting  Lessor or Beneficiary to
            any unreasonable  cost or expense.  If and to the extent that Lessor
            and Beneficiary  fail to file or provide any such return,  statement
            or other  documentation  (as to which,  in the case of any such item
            required by a change in applicable  law or treaty after the Delivery
            Date,  Lessee has notified  them) and as a result thereof either (i)
            tax  withholding  is  required  at a rate which is higher  than that
            which would have been applicable had such return, statement or other
            documentation  been filed or  provided  or (ii) tax  withholding  is
            required  which  would  not have  been  required  had  such  return,
            statement or other  documentation  been filed or provided,  Lessee's
            obligation to make the increased payment otherwise  required by this
            paragraph of Article  8.2(ii)  hereof shall be limited to the amount
            which would have been required if Lessor or Beneficiary had filed or
            provided such return, statement or other documentation.

            If,  as a  result  of any  change  in  applicable  statutory  or any
            applicable tax law or treaties which has an effective date after the
            Delivery  Date,  including,  without  limitation,  an  Irish  Treaty
            Change,  any  withholding  or  deduction  is  required to be made by
            Lessee (or Lessor as withholding agent) and/or taxes, fees and other
            charges  indemnified  by Lessee  pursuant  to this  Article  8.2 are
            imposed in an amount  which  increases  the cost to Lessee of making
            Basic Rent  payments  hereunder by more than ten (10) percent in any
            calendar year, the parties will in good faith  negotiate for 60 days
            following  written notice from Lessee a method of restructuring  the
            transaction  in order to avoid the  withholding,  deduction,  taxes,
            fees or other  charges  (during  which period  Lessee shall make all
            payments in the full amount required  hereby) and if no solution can
            be found in such period which is  acceptable  to the  parties,  then
            Beneficiary  will begin  remarketing  the  Aircraft on such 60th day
            (the "Remarketing  Commencement  Date").  For the period starting on
            the Remarketing  Commencement Date, and ending on the earlier of (i)
            the date of sale or  commencement  of a new lease for the  Aircraft,
            and (ii) twelve months from the Remarketing  Commencement Date, this
            Lease will continue (unless terminated by Lessor as provided below),
            Lessee  will  continue  to pay Basic Rent  (including  any  gross-up
            required by this Article 8.2(11)), and Beneficiary will remarket the
            Aircraft.  During such period,  Lessor may require  Lessee to return
            the Aircraft upon thirty days' prior written notice and, on the date
            the  Aircraft  is  returned,  it shall  meet the  return  conditions
            required  herein this Lease  Agreement  shall  terminate  and Lessee
            shall pay the Termination Value to Beneficiary.

      (iii) If  such a  change  of  law or  treaty  described  in the  preceding
            paragraph  occurs and has an  effective  date prior to the  Delivery
            Date such that Beneficiary's representation above would be incorrect
            in any material  respect on the Delivery  Date,  the parties will in
            good faith attempt to restructure  the transaction to avoid any such
            tax  withholding  and if no solution  can be found by the  Scheduled
            Delivery Date,  which is acceptable to the parties,  Beneficiary may
            terminate  this Lease and will return the amounts paid in respect of
            the Security Deposit, plus interest thereon at the rate paid on such
            deposit by Beneficiary's bank.

      In addition,  and not by way of limiting the  foregoing,  Lessee agrees to
      pay and to indemnify and hold harmless  Lessor and  Beneficiary  from, all
      license fees and all taxes, levies, imposts, duties, assessments,  charges
      and  withholdings of any nature  whatsoever,  together with any penalties,
      additions to tax, fines and interest thereon  (collectively,  "taxes, fees
      and other charges") imposed against the Lessor, Beneficiary, Lessee or any
      item of  Equipment or any part  thereof by any  Federal,  state,  or local
      government or governmental  subdivision or taxing  authority in the United
      States of America or any possession or territory thereof,  or by any other
      country or international taxing authority, or by any subdivision or taxing
      authority of any of the foregoing upon or with respect to the Equipment or
      any part thereof, or interest therein, or upon the manufacture, financing,
      servicing,   maintenance,   warranty,   repair,   replacement,   insuring,
      improvement, transfer of title, purchase, erection, installation, testing,
      acceptance  or  rejection,  ownership,  delivery,   non-delivery,   lease,
      sublease,  rental,  acquisition,  registration,  rebuilding,  abandonment,
      transportation,  storage,  possession,  use, operation,  condition,  sale,
      return or other  disposition  thereof,  or upon the  rentals,  receipts or
      earnings arising  therefrom,  or with respect to any contract  relating to
      the manufacture, construction, acquisition or delivery of the Equipment or
      otherwise with respect to the transactions contemplated by this Agreement.

      Notwithstanding the foregoing,  the indemnity provided for in this Article
      8.2 does not extend to any Lessor Taxes or to any withholding of US income
      taxes except to the extent provided in Article 8.2(ii) hereof.

      If a claim is made against Lessor or Beneficiary  for any taxes,  fees and
      other   charges  for  which   Lessor  or   Beneficiary   intends  to  seek
      indemnification  hereunder,  Lessor or Beneficiary  shall promptly  notify
      Lessee. If requested by Lessee in writing, Lessor or Beneficiary shall, in
      good faith contest or, at Lessee's request if permitted by applicable law,
      permit  Lessee  to  contest  (and in such  case,  provide  all  reasonable
      cooperation  to  Lessee)  the  validity,  applicability  or amount of such
      taxes,  fees  and  other  charges  by (A)  resisting  payment  thereof  if
      practicable,  (B) paying the same under  protest,  if protest is necessary
      and proper, or (C) if payment be made, using reasonable  efforts to obtain
      a refund thereof, in appropriate  administrative and judicial  proceedings
      including  appeals  other  than  to  the  Supreme  Court.  Notwithstanding
      anything to the contrary herein,  in no event shall Lessor and Beneficiary
      be required or Lessee  permitted to contest the  imposition  of any taxes,
      fees or other charges  asserted  against Lessor or  Beneficiary  for which
      Lessee is obligated pursuant to this Section 8.2 unless (i) on demand from
      time to time,  Lessee pays any and all expenses  incurred by Lessor and/or
      Beneficiary  reasonably  allocable  to such  contest  (including,  without
      limitation,  all costs,  expenses,  losses,  legal and accounting fees and
      disbursements),  (ii) no Event under  Article  14.1(a) or Event of Default
      shall have occurred and be  continuing,  (iii) the action to be taken will
      not  result  in the  likelihood  of sale,  forfeiture  or loss of,  or the
      creation of any lien on the Equipment or any interest  therein  (except if
      Lessee shall have adequately  bonded such lien or otherwise made provision
      to protect the interests of Lessor and Beneficiary in a manner  reasonably
      satisfactory   to  Lessor  and  Beneficiary  or  result  in  any  criminal
      penalties, and (iv) Lessee shall have delivered to Lessor and Beneficiary,
      at Lessee's sole expense,  an opinion of independent tax counsel  selected
      by Lessee and reasonably acceptable to the indemnified party to the effect
      that a  reasonable  basis for such  contest  exists.  If any such  contest
      involves payment of the taxes, fees and other charges in question,  Lessee
      shall either make such payment  directly to the  appropriate  authority or
      furnish to Lessor and Beneficiary sufficient funds on an interest-free and
      after-tax basis to make such payment.  Lessor or Beneficiary,  as the case
      may be,  shall  consult with Lessee in good faith  regarding  the means of
      contesting such claim and shall keep Lessee reasonably  informed regarding
      the  progress of such  contest.  If Lessor or  Beneficiary  shall obtain a
      refund of or be entitled to a credit  against  other  liability for all or
      any part of such taxes,  fees and other charges paid by Lessee,  Lessor or
      Beneficiary  as the case may be shall pay Lessee the amount of such refund
      (or credit),  after deducting all costs and expenses that were incurred by
      Lessor or Beneficiary in connection  therewith;  provided,  however,  that
      such amount shall in no event be payable  before such time as Lessee shall
      have made all payments and  indemnities  then due to Lessor or Beneficiary
      under this Agreement; provided further, however, that the aggregate amount
      of all payments  pursuant to this sentence by Lessor or  Beneficiary  with
      respect  to any  taxes,  fees and  other  charges  shall  not  exceed  the
      aggregate  amount of all payments made by Lessee  pursuant to this Section
      8.2 with respect to such taxes, fees and other charges.  If in addition to
      such  refund (or credit)  Lessor or  Beneficiary  shall  receive an amount
      representing  interest on the amount of such refund (or credit),  or would
      have received interest but for an offsetting liability for taxes, fees and
      other charges not indemnified by Lessee  hereunder,  Lessee shall promptly
      be paid that portion of such  interest (or such  interest  that would have
      been  received)  that is fairly  attributable  to any tax,  fees and other
      charges paid or  reimbursed  by Lessee prior to the receipt of such refund
      for the period from Lessee's  payment or  reimbursement  to the payment to
      Lessee of such  refund,  reduced  by the amount of any  Federal,  state or
      local  income  taxes  payable  by the  Indemnified  Party by reason of the
      receipt or accrual of such interest and increased by the amount of any tax
      benefits resulting from such payment to Lessee; provided, however, that no
      amount shall be payable  under this or the preceding  sentence  during any
      period in which an Event of Default has  occurred  and is  continuing.  If
      Lessor or  Beneficiary  receives an award of attorney's  fees in a contest
      for which  Lessee has paid an allocable  portion of the contest  expenses,
      Lessor  or  Beneficiary,  as  applicable,  shall  pay to  Lessee  the same
      proportion  of the amount of such award as the amount of  attorney's  fees
      paid or reimbursed  by Lessee bears to the total amount of the  attorney's
      fees  actually  incurred  by  Lessor or  Beneficiary,  as  applicable,  in
      conducting  such  contest.  In case any report or return is required to be
      made with respect to any obligation of Lessee under or arising out of this
      Article 8.2,  Lessee will either make such report or return in such manner
      as will show the  ownership  of Lessor in the  Aircraft and send a copy of
      such report or return to Lessor, or will notify Lessor of such requirement
      and make  such  report or  return  in such  manner as shall be  reasonably
      satisfactory  to Lessor.  Lessor shall provide to Lessee such  information
      within  its  possession  or control as is  necessary  to enable  Lessee to
      properly make such return or report.

      If Lessor or Beneficiary  shall release,  waive,  compromise or settle, or
      fail  to  pursue  any   required   contest  of  any  claim  which  may  be
      indemnifiable  by Lessee  pursuant to this Article 8.2 without the written
      permission  of  Lessee,   Lessee's   obligation  to  indemnify  Lessor  or
      Beneficiary  with respect to such claim (and all directly  related  claims
      and claims based on the outcome of such claim) shall terminate, and Lessor
      or Beneficiary, as applicable, shall repay to Lessee any amount previously
      paid or advanced  with  respect to such claim,  plus  interest at the rate
      that would have been payable by the relevant taxing authority with respect
      to a refund of such taxes,  fees and other  charges.  Notwithstanding  the
      foregoing,  Lessor and  Beneficiary  will not be  required  to contest the
      imposition of any taxes,  fees and other charges and shall be permitted to
      settle or compromise any claim without  Lessee's consent if such Lessor or
      Beneficiary,  as applicable,  (I) shall waive its right to indemnity under
      this Article 8.2 with respect to such taxes,  fees and other  charges (and
      any  directly  related  claim  and any  claim  the  outcome  of  which  is
      determined  based upon the  outcome  of such  claim) and (II) shall pay to
      Lessee any amount  previously  paid or advanced by Lessee pursuant to this
      Article 8.2 with respect to such Tax, plus interest at the rate that would
      have been  payable by the  relevant  taxing  authority  with  respect to a
      refund of such taxes, fees and other charges.

      Lessee further agrees that any payment or indemnity made under Article 8.1
      or this Article 8.2 by Lessee shall  include any amount  necessary to hold
      Lessor and Beneficiary harmless on an after-tax basis (after giving effect
      to all  deductions,  credits  and  other  tax  benefits  available  to the
      recipient  of  such   indemnity   payments  with  respect  to  the  matter
      indemnified  under  Article  8.1 or with  respect to the  payments  of the
      taxes,  fees and other  charges  indemnified  under  Article 8.2) from all
      taxes, fees and other charges required to be paid by Lessor or Beneficiary
      with respect to such  payment or indemnity  under the laws of any domestic
      or foreign governmental or taxing authority, agency or subdivision.

      At Lessee's  request,  the computation of any amount owed by Lessee or any
      amount owed to Lessee by an  Indemnitee  pursuant to Article 8.1 hereof or
      by Lessor or  Beneficiary  pursuant to this  Article 8.2 shall be verified
      and certified by an independent  public accounting firm selected by Lessee
      and  reasonably  satisfactory  to the  applicable  Indemnitee,  Lessor  or
      Beneficiary,  as the case may be.  Such  verification  shall be binding on
      both Lessee and such Indemnitee, Lessor and Beneficiary. The costs of such
      verification  (including the fee of such public  accounting firm) shall be
      borne by Lessee unless such verification  shall result in an adjustment in
      Lessee's  favor of 10% or more of the net present  value of the payment as
      computed by such Indemnitee,  Lessor or Beneficiary,  as applicable.  Such
      Indemnitee,  Lessor or Beneficiary,  as applicable,  shall provide to such
      public accounting firm on a confidential basis all information  reasonably
      necessary for such verification.

      All of the rights and  obligations  of Lessee under this Article 8.2 shall
      continue  in  full  force  and  effect  to  the  extent   provided  herein
      notwithstanding  the  expiration or sooner  termination  of this Lease and
      such  obligations  are  expressly  made for the  benefit  of, and shall be
      enforceable by, Lessor and Beneficiary and their respective successors.
      and assigns.

ARTICLE 9.  DAMAGE, DESTRUCTION, REQUISITION, CONDEMNATION

9.1 EVENT OF LOSS WITH RESPECT TO THE AIRCRAFT.

      Upon the  occurrence  of an Event of Loss with  respect to the Airframe or
      the  Airframe and any Engines or engines then  installed  thereon,  Lessee
      shall give Lessor and  Beneficiary  prompt  written notice thereof (and in
      any event within two  Business  Days) and shall pay or cause to be paid to
      Beneficiary  on the 90th day after such  Event of Loss (or  earlier if the
      insurance or other proceeds have been paid earlier):  (i) the Agreed Value
      in respect of the  Aircraft,  and (ii) all other Rent,  other than amounts
      paid pursuant to Clause (i), then due and payable hereunder.  At such time
      as  Beneficiary  has  received  the sum of (i),  and (ii)  above:  (A) the
      obligation  of Lessee to pay Basic  Rent  hereunder  with  respect to such
      Aircraft  shall  terminate and (B) the Term for the Aircraft shall end and
      (C) Lessor shall transfer full legal and beneficial  title to the Aircraft
      to Lessee (or, if applicable,  to Lessee's insurers) free of all rights of
      Beneficiary  and all Lessor's  Liens. An Event of Loss with respect to the
      Airframe  shall be deemed to  constitute  an Event of Loss with respect to
      the Aircraft.

9.2 EVENT OF LOSS WITH RESPECT TO AN ENGINE.

      Upon the occurrence of an Event of Loss with respect to an Engine not then
      installed  on the  Airframe,  or in the Event of Loss with  respect  to an
      Engine  installed on the Airframe but not  involving an Event of Loss with
      respect to such Airframe,  Lessee shall give Lessor and Beneficiary prompt
      written  notice  thereof (and in any event within five Business  Days) and
      Lessee  shall,  as promptly as possible  and in any event  within 120 days
      after the  occurrence of such Event of Loss,  duly convey to Lessor,  as a
      replacement  for the  Engine  with  respect  to which  such  Event of Loss
      occurred, title to another CFM56-3B2 engine owned by Lessee free and clear
      of all Liens and having,  unless Beneficiary otherwise agrees, a value and
      utility at least equal to, and being in as good  operating  condition  as,
      the Engine  with  respect to which such Event of Loss  occurred,  assuming
      such Engine was of the value and utility and in the  condition  and repair
      required by the terms hereof  immediately  prior to the occurrence of such
      Event of Loss.  Lessee shall demonstrate to Lessor's Tech Rep's reasonable
      satisfaction  the value and utility of any substitute  engine by providing
      all necessary  information  and data in respect of such engine as Lessor's
      Tech Rep  shall  reasonably  request.  In such  case,  Lessee,  at its own
      expense, will promptly (i) furnish Lessor with a bill of sale, in form and
      substance  satisfactory to Lessor and  Beneficiary,  for such  replacement
      engine, (ii) execute a supplement hereto in form and substance  reasonably
      satisfactory to Lessor and Beneficiary  subjecting such replacement engine
      to this Lease,  (iii)  furnish  Lessor and  Beneficiary  with  evidence of
      Lessee's title to such replacement  engine  (including,  if requested,  an
      opinion  of  Lessee's  counsel)  and  of  compliance  with  the  insurance
      provisions of Article 10 hereof with respect to such replacement engine as
      Lessor and  Beneficiary may reasonably  request,  and (iv) take such other
      action as Lessor  and  Beneficiary  may  reasonably  request in order that
      title to such replacement engine be duly and properly vested in Lessor and
      leased hereunder to the same extent as the Engine replaced  thereby.  Upon
      full  compliance by Lessee with the terms of this Article 9.2, Lessor will
      transfer to Lessee,  without  representation,  recourse or warranty of any
      kind,  express or implied  (except a warranty  that such Engine is free of
      Lessor  Liens,  other than Liens which  Lessee is  required  to  discharge
      hereunder,  and all rights of Beneficiary  and defects in title  resulting
      from Lessor's acts), all of Lessor's right, title and interest, if any, in
      and to the Engine with respect to which such Event of Loss  occurred  and,
      for all  purposes  hereof,  such  replacement  engine  shall be  deemed an
      Engine.  No Event of Loss with  respect to an Engine  shall  result in any
      reduction in Basic Rent.

9.3   APPLICATION OF PAYMENTS FROM GOVERNMENTAL AUTHORITIES IN RESPECT OF
      EVENT OF LOSS.

      Any payments (other than insurance  proceeds,  the application of which is
      provided  for in  Article  10  hereof)  received  at any  time by  Lessor,
      Beneficiary or Lessee from any governmental authority or other person with
      respect to an Event of Loss with respect to any item of Equipment  will be
      applied as follows:

          i.      if such payments are received with respect to an Event of Loss
                  relating to the  Airframe or the  Airframe  and the Engines or
                  engines  installed on such Airframe,  after  reimbursement  of
                  Lessor and Beneficiary for its reasonable  out-of-pocket costs
                  and  expenses  if any,  so much of such  payment  as shall not
                  exceed  the  amounts  due under  Article 9 shall be applied in
                  reduction of Lessee's  obligation to pay such amounts,  if not
                  already paid by Lessee,  or, if already paid by Lessee,  shall
                  be  applied  to  reimburse  Lessee  for  its  payment  of such
                  amounts,  and the balance,  if any, of such payment  remaining
                  thereafter to the extent not exceeding Lessee's Interest shall
                  be paid to Lessee,  and the  balance,  if any, of such payment
                  remaining  thereafter  will be paid  over  to or  retained  by
                  Beneficiary; and

         ii.      if such  payments are received with respect to an Engine under
                  circumstances  contemplated  Article  9.2,  so  much  of  such
                  payments remaining after  reimbursement of Beneficiary for its
                  reasonable  out-of-pocket costs and expenses, if any, shall be
                  paid over to, or retained  by,  Lessee,  provided  that Lessee
                  shall have fully  performed  or  concurrently  therewith  will
                  fully perform the terms of Article 9.2.

9.4   REQUISITION OF AN AIRFRAME FOR USE BY GOVERNMENT.

      In the event of the  requisition  for use by the  Government of the United
      States of  America  ("Government")  of the  Airframe  and the  Engines  or
      engines installed thereon during the Term therefor,  Lessee shall promptly
      notify  Lessor and  Beneficiary  of such  requisition  and all of Lessee's
      obligations  under  this  Lease  Agreement  with  respect to such items of
      Equipment shall continue to the same extent as if such requisition had not
      occurred  (except to the extent that compliance  with such  obligations by
      Lessee  is not  possible  as the  result of such  requisition);  PROVIDED,
      HOWEVER,  that if such items of  Equipment  are not returned to the Lessor
      prior to the end of the Term  therefor,  the Term shall  automatically  be
      extended  until  such  requisition  for use  ceases  (subject  to the next
      PROVISO) and such  Equipment is returned to Lessor in compliance  with the
      provisions  of  Article  13 as soon as  reasonably  practicable  after its
      return by the  Government,  and,  during such extended Term,  Lessee shall
      continue  to  perform  all  obligations   under  this  Lease  as  if  such
      requisition for use had not occurred (except to the extent that compliance
      with such  obligations  by Lessee is not  possible  as the  result of such
      requisition); PROVIDED FURTHER, HOWEVER, if such Equipment is not returned
      to Lessor prior to the first anniversary of the extended Term contemplated
      by this Article 9.4 in full compliance  with Article 13, at  Beneficiary's
      sole option such  Equipment  shall be deemed to have been  subjected to an
      Event of Loss as of such  anniversary date and Lessee shall, on such date,
      pay to  Beneficiary  the Agreed  Value.  Lessee  shall be  entitled to all
      compensation  payable by the Government  with respect to such  requisition
      and, to the extent received by Lessor or  Beneficiary,  shall be paid over
      to Lessee on receipt.

9.5   REQUISITION OF AN ENGINE FOR USE BY THE GOVERNMENT.

      In the event of the  requisition  for use by the  Government of any Engine
      without  the  requisition  for  use of the  Airframe,  if  and  when  such
      requisition  exceeds 180 consecutive days, Lessee will replace such Engine
      hereunder by complying with the terms of Article 9.2 to the same extent as
      if an Event of Loss had  occurred  with  respect to such  Engine,  and any
      payments  received  by  Beneficiary  or Lessee  from the  Government  with
      respect to such requisition shall be paid over to, or retained by, Lessee.

9.6   APPLICATION OF PAYMENTS DURING EXISTENCE OF EVENT OR EVENT OF DEFAULT.

      Any amount  referred to in clause (i) or (ii) of Article 9.3 or in Article
      9.4 or 9.5 which is payable  to Lessee  shall not be paid to Lessee or, if
      such amount has been previously  paid to Lessee,  shall not be retained by
      Lessee,  if at the time of such  payment  an Event  described  in  Article
      14.1(a) or Event of Default shall have occurred and be continuing. In such
      event,  all  such  amounts  shall be paid to and  held by  Beneficiary  as
      security for the performance by Lessee of its obligations hereunder or, at
      Beneficiary's option, applied by Beneficiary toward payment of any of such
      obligations of Lessee at the time due hereunder as Beneficiary  may elect.
      At such time as Lessee  shall  have  cured all such  Events  and Events of
      Default, all such amounts at the time held by Beneficiary in excess of the
      amounts,  if any, which  Beneficiary  shall have elected to apply as above
      provided shall be paid to Lessee.

ARTICLE 10.  INSURANCE

10.1  From the Delivery Date and at all times during the Term and thereafter, to
      the extent  provided in Article  10.7,  Lessee  shall be  responsible  for
      effecting and  maintaining  or causing to be effected and  maintained,  in
      full  force and  effect,  insurance  in respect  of the  Aircraft  in form
      comparable to that  maintained by other  similarly-situated  United States
      airlines  (the  "Insurance"  which  expression  shall where the context so
      admits include any relevant  re-insurance(s)  obtained in respect thereof)
      through the Approved  Insurance  Broker.  The  Insurance  will be effected
      either (1) on a direct  basis with  insurers of  recognized  standing  who
      normally  participate in aviation insurance in the London,  United States,
      European or Japanese aviation  insurance markets  (collectively,  together
      with such other aviation  insurance  market(s) as Beneficiary may approve,
      such approval not to be unreasonably withheld or delayed,  "World Aviation
      Insurance  Markets")  (such  insurers  to be led in any case by  reputable
      underwriter(s)  who  regularly  participate  in World  Aviation  Insurance
      Markets) or (2) with such an insurer who will effect  reinsurance  of such
      primary  insurance,  in  whole or in part,  in  World  Aviation  Insurance
      Markets.  In the latter  case,  Lessee  shall  procure  that the  Approved
      Insurance  Broker  maintains  in full force and effect  reinsurances  with
      reinsurers in the World  Aviation  Insurance  Markets and through  brokers
      each of recognized  standing who regularly deal in such insurance  markets
      for that  percentage  of the risks  insured not retained on a direct basis
      (the "Reinsurance").

10.2  The  requirements  at the date of this Agreement as to required  Insurance
      are as specified  in this  Article 10 and in Exhibit "G". The  Beneficiary
      acting  reasonably and in consultation  with Lessee shall be entitled from
      time to time to stipulate other reasonable  insurance  requirements (other
      than  those  prescribed  in this  Article  10 or  Exhibit  "G") to reflect
      changes in insurance  practice  relating to the method in which  insurable
      risks  are  covered  in World  Aviation  Insurance  Markets,  which  other
      insurance  requirements  shall be in  accordance  with normal  practice of
      organizations   operating  similar  aircraft  in  similar   circumstances;
      provided, however, that any such further requirements shall be of the type
      generally available in such markets at commercially reasonably rates.

10.3  If at any time due to changes in World Aviation  Insurance Market practice
      or custom, it becomes or will become commercially impracticable for Lessee
      to comply  with its  obligations  under this  Article 10 or in Exhibit "G"
      then the Lessee  shall  forthwith  notify the  Beneficiary  and as soon as
      practicable  thereafter Beneficiary and Lessee shall in good faith consult
      as to what changes,  if any,  might be made to the terms and conditions of
      the insurance  required  hereunder in order to take account of the changes
      in World  Aviation  Insurance  Market  practice  or custom  and as to what
      amendments, if any, should be made to the provisions of this Article 10 or
      Exhibit  "G"  provided no  amendment  to the  insurances  required by this
      Article 10 and Exhibit "G" shall be effective  unless and until  consented
      to by Beneficiary.

10.4  [Intentionally Omitted]

10.5  Lessee shall:-

      (a)   ensure that all legal  requirements  as to insurance of the Aircraft
            or any Part  thereof  which may from time to time be  imposed by the
            United States or any state to, from or over which the Aircraft shall
            be flown,  in so far as they affect or concern the  operation of the
            Aircraft,  are complied  with and in particular  those  requirements
            compliance  with which is  necessary to ensure that (a) the Aircraft
            is not in danger  of  detention  or  forfeiture,  (b) the  Insurance
            remain valid and in full force and effect,  and (c) the interests of
            the  Indemnities  in the  Insurance  and the  Aircraft  or any  part
            thereof are not thereby prejudiced;

      (b)   not use,  cause or permit the Aircraft to be used for any purpose or
            in  any  manner  not  covered  by  the   Insurance  or  outside  any
            geographical  limit imposed by such  Insurance or for any purpose or
            in any manner  which is contrary to  applicable  Law.  Lessee  shall
            comply and procure compliance, with the terms and conditions of each
            and every policy of the Insurance and shall not do, consent or agree
            to any  act or  omission  which  invalidates  or may  invalidate  or
            renders  unenforceable or may render  unenforceable the whole or any
            part of any such Insurance;

      (c)   ensure that no insurance or  reinsurance  in respect of the Aircraft
            other than those  required under this Article 10 and Exhibit "G" are
            taken out if such other  insurance or  reinsurances  would prejudice
            Lessor's  or  Beneficiary's  rights with  respect to the  Insurance.
            Lessor and Beneficiary  agree that subject to the foregoing,  Lessee
            may maintain  hull and other  insurance in relation to the Aircraft,
            Engines or Parts  thereof.  Insurance  proceeds  arising out of such
            insurance shall be paid to Lessee;

      (d)   ensure that the renewal negotiation is commenced prior to expiration
            of any of the Insurance.  If requested by Beneficiary in writing,  a
            written  status report shall be given to the Lessor and  Beneficiary
            seven (7) Business Days prior to expiry date. Facsimile confirmation
            of  completion  of renewal  shall be  provided  by the Lessee to the
            Lessor and the  Beneficiary  at least two (2)  Business  Days before
            such  expiry.  Certificates  of  insurance  (and  where  appropriate
            Certificates of reinsurance), in the English language, detailing the
            coverage and  confirming  the  insurers' (or as the case may be, the
            reinsurers')  agreement to the specified  insurance  requirements of
            this Lease must be  provided to Lessor and  Beneficiary  at delivery
            and within seven days after each renewal date;

      (e)   if requested  by  Beneficiary,  provide or procure the  provision to
            Lessor  or  Beneficiary  of  copies  of  documents   evidencing  the
            Insurance  upon request if there is a denial of  coverage;  provided
            always that Lessor and  Beneficiary  shall not disclose the contents
            of actual  insurance  policies to third  parties  other than (i) its
            professional  advisors,  (ii) as may be required by applicable  law,
            and (iii) when  required to settle a dispute over  coverage  but, in
            any  such  event,  shall  take  such  actions  in good  faith as may
            reasonably be requested by Lessee to protect the  confidentiality of
            such documents;

      (f)   on  request,   provide  or  procure  the  provision  to  Lessor  and
            Beneficiary of evidence of premium payment;

      (g)   promptly  notify  Beneficiary  of any occurrence (i) with respect to
            which Lessee  believes the cost of repairs to the Airframe,  Engines
            or any Part will  exceed,  or (ii) which is likely to give rise to a
            claim in excess  of,  the  Damage  Notification  Threshold  for Hull
            claims  and US$[ ]* for  claims  arising  under the legal  liability
            insurance;

      (h)   not make or cause to be made any  modification  or alteration to the
            Insurance  which is adverse and material to any of the  Indemnities,
            nor do or leave undone anything which  reasonably  would be expected
            to invalidate the insurance coverage;

      (i)   be responsible for any deductible/excluded loss under the Insurance;

      (j)   subject to the  limitations  of 10.5(e),  provide and cause Lessee's
            insurance  broker to provide  any other  insurance  and  reinsurance
            related  information,  or assistance,  as Beneficiary may reasonably
            request;

      (k)   reimburse  Lessor and/or the Beneficiary for any premiums  (together
            with interest thereon at the Incentive Rate from the date of payment
            until the date of  reimbursement)  paid by any of them  pursuant  to
            Article 10.6.

10.6  If at any time Lessee fails to maintain the Insurance  (without  prejudice
      to any other rights which Lessor may have acquired under this Agreement by
      reason of such  failure),  Lessor and the  Beneficiary  shall,  after such
      advance notice to and  consultation  (if possible) with Lessee as shall be
      reasonable under the circumstances, be entitled

      (a)   to pay the premiums due or, in the event  Lessor or  Beneficiary  is
            not  allowed to pay such  premiums,  with notice to Lessee to effect
            and maintain similar  insurance  satisfactory to it. Such sums so as
            shall have been so expended by it shall, upon written demand, become
            immediately due and payable by Lessee together with interest thereon
            at the Incentive  Rate, from the date of expenditure by it up to the
            date of reimbursement by Lessee;

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

10.7  Beneficiary  shall be  entitled,  after the expiry or  termination  of the
      leasing of the Aircraft, to require Lessee at Lessee's expense to maintain
      legal  liability  insurance  under  Lessee's  fleet policies in the amount
      required  immediately prior to the expiry or termination of the leasing of
      the Aircraft insofar as the same relates to the Aircraft for two (2) years
      after  the end of the  Term  such  insurance  to  provide  for each of the
      Indemnities to be named as additional  insured thereunder to the extent of
      its interest under the said  indemnities,  and the obligation of Lessee to
      effect the same shall not be  affected  by Lessee  ceasing to be lessee of
      the Aircraft  and/or any of the  Indemnities  ceasing to have any interest
      in, or in respect of, the Aircraft.

10.8  Notwithstanding  any other provision of this Lease, Lessor and Beneficiary
      agree  to  accept,   in  lieu  of  the   insurance   required   hereunder,
      indemnification  from,  or  insurance  provided by the  government  of the
      United States (or any agency or instrumentality thereof the obligations of
      which  (including  this  indemnity)  are  supported  by the full faith and
      credit of the government of the United States), against the risks required
      to be insured  pursuant to this  Article 10 and in an amount  which,  when
      added to the amount of any such insurance  maintained by Lessee,  shall be
      at least equal to the amounts which Lessee would  otherwise be required to
      maintain  hereunder.  Such indemnity or written evidence of such insurance
      shall be provided to Lessor and  Beneficiary  at least three Business Days
      prior to the date on which such insurance would become effective as to the
      Aircraft.

10.9 APPLICATION OF INSURANCE PROCEEDS FOR AN EVENT OF LOSS.

      It is agreed  that  insurance  payments  which  arise  from any  policy of
      insurance  carried by Lessee and received as the result of the  occurrence
      of an Event of Loss shall be applied as follows:

      (i) if such  payments  are  received  with  respect  to an  Event  of Loss
      relating to the Airframe and Engines or engines installed on the Airframe,
      so much of such payments as shall not exceed the amounts due under Article
      9.1 hereof shall be paid to Beneficiary for immediate  application towards
      sums owed by Lessee, and the balance to Lessee; and

      (ii) if such  payments  are  received  with  respect  to an  Event of Loss
      relating  to an Engine  under  circumstances  contemplated  by Article 9.2
      hereof,  such payment  shall be paid over to Lessee,  provided that Lessee
      shall have fully performed or, concurrently therewith,  fully performs the
      terms of Article 9.2 hereof.

10.10 APPLICATION OF INSURANCE PROCEEDS FOR OTHER THAN AN EVENT OF LOSS.

      Except as otherwise  provided in Exhibit G hereto,  the insurance payments
      for  any  property   damage  loss  to  the  Airframe  or  any  Engine  not
      constituting  an Event of Loss, or to any Part, may be held by Beneficiary
      until Lessee  furnishes  Beneficiary with  satisfactory  evidence that the
      repairs or replacement property Lessee is required to perform or obtain in
      accordance  with the terms of Article 5 and 6 of this Lease have been made
      or an  agreement  with the  Manufacturer  or other third  person or entity
      reasonably  satisfactory  to  Beneficiary  has been  entered  into for the
      replacement  of such  damaged  item or the  completion  of the  repairs by
      Lessee. In any event, whether repairs are made by Lessee or a third party,
      Insurance  payments will be applied and made available by Beneficiary upon
      reasonable  request by Lessee in  periodic  progress  payments  as work is
      accomplished and/or replacement effected. Upon receipt of such evidence of
      repair or replacement or contract,  Beneficiary  shall pay Lessee,  if the
      repairs have been completed, or to the Manufacturer or such other repairer
      for such  repairs,  the  amount of the  insurance  payment  received  with
      respect to such loss. Any balance of insurance  proceeds  remaining  after
      such  payments  and  completion  of such  repairs,  shall be paid  over to
      Lessee.

10.11 APPLICATION IN DEFAULT.

      Any amount referred to in Article 10.9 or Article 10.10 which is otherwise
      payable  to  Lessee  shall  not be  paid to  Lessee,  or,  if it has  been
      previously paid to Lessee, shall be delivered by Lessee to Beneficiary, if
      at the time of such payment, an Event under Article 14.1(a) or an Event of
      Default shall have occurred and be  continuing.  In either case,  all such
      amounts shall be held by  Beneficiary  as security for the  obligations of
      Lessee or, at the option of  Beneficiary,  applied by  Beneficiary  toward
      payment of any of Lessee's obligations at the time due hereunder.  At such
      time as there shall not be continuing  any such Event or Event of Default,
      all such amounts at the time held by  Beneficiary in excess of the amount,
      if any, which  Beneficiary  has elected for  application as provided above
      shall be paid to Lessee.

ARTICLE 11.  MORTGAGES, LIENS, ETC.

      Lessee shall not directly or indirectly create, incur, assume or suffer to
exist any Lien on or with respect to any item of  Equipment,  any part  thereof,
title thereto or any interest  therein,  except:  (i) the  respective  rights of
Lessor and Lessee as herein  provided and the rights of any financier  under any
mortgage granted by Lessor to such financier at the request of Beneficiary, (ii)
Lessor Liens,  (iii) Liens for taxes,  fees and other charges (other than Lessor
Taxes)  either  not yet due or being  contested  in good  faith  by  appropriate
proceedings,  but only so long as such proceedings do not involve the likelihood
of the sale,  forfeiture or loss of any item of Equipment,  or interest therein,
and (iv) inchoate materialmen's,  mechanics', workmen's, repairmen's,  employees
or other like liens  arising in the ordinary  course of business and for amounts
the  payment of which is either not  delinquent  or is being  contested  in good
faith by appropriate  proceedings,  but only so long as such  proceedings do not
involve the likelihood of the sale, forfeiture or loss of any item of Equipment,
or any interest  therein (such Liens described in clauses (i) through (iv) above
being referred to herein as "Permitted  Liens").  Lessee shall promptly,  at its
own expense, take such action as may be necessary to duly discharge any Lien not
excepted above if the same shall arise at any time with respect to any Equipment
leased hereunder.

      If any Lien (other than in favor of the  Beneficiary) is created by Lessor
or Beneficiary on the Aircraft or this Lease securing  indebtedness,  the Lessee
shall cooperate with Beneficiary,  at Beneficiary's  expense,  in perfecting the
rights of the financier and the  Beneficiary  shall cause the lender before such
Lien is effected to provide a Letter of Quiet Enjoyment to Lessee.

ARTICLE 12.  RECORDATION AND FURTHER ASSURANCES

      Lessor,  Beneficiary and Lessee will promptly and duly execute and deliver
to Lessor or Beneficiary or Lessee,  as applicable,  such further  documents and
assurances  and take such further  action as Lessor,  Beneficiary  or Lessee 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  hereunder,  including,  without
limitation, if requested by Lessor or Beneficiary, at the expense of Lessee, the
execution and delivery of supplements or amendments  hereto, in recordable form,
subjecting to this Lease any  replacement  engine and the recording or filing of
counterparts thereof, or of financing statements with respect thereto for filing
in the state in which the  principal  office of Lessee is  located.  Lessee will
consent to the  assignment of this Lease to a financier if requested to do so by
Beneficiary  and will  cooperate  in amending the  insurances  to cover any such
assignee  as an  additional  assured;  provided  that no such  assignment  shall
diminish the rights and  privileges  of Lessee  hereunder  or increase  Lessee's
obligations hereunder.

ARTICLE 13.  RETURN OF AIRCRAFT AND RECORDS

13.1  RETURN.

      Except as otherwise provided herein, at the expiration of the Term for the
      Equipment or upon the sooner termination of this Lease, Lessee, at its own
      expense,  shall return the Equipment to Lessor by  delivering  the same to
      Lessor at Lessee's facilities in Colorado Springs, Colorado or at those of
      the Authorized  Maintenance Performer performing the redelivery "C" check.
      Lessee  will,  at  Beneficiary's  request,  ferry  the  Aircraft  from the
      redelivery  location to any other location within the 48 contiguous United
      States of America,  as may be designated by Beneficiary,  at Beneficiary's
      expense.  The  Aircraft,  at the time of return to Lessor,  shall be fully
      equipped  with  Engines or other  CFM56-3B2  engines  owned by Lessee (and
      complying with Article 13.3) properly installed thereon.  In addition,  on
      redelivery  the Aircraft  shall comply in all respects with the Redelivery
      Conditions stated in Exhibit "E" to this Lease.

13.2  OVERHAUL - GENERAL.

      Immediately prior to such return of the Aircraft, Lessee shall have caused
      a "C" check, to have been performed to the Airframe,  at Lessee's cost, in
      accordance with Exhibit "E" hereto.

13.3  ENGINES.

      In the event any engine not owned by Lessor  shall be  delivered  with the
      Airframe,  such engine shall be free and clear of Liens, of the same model
      (or an improved version) and Manufacturer as the replaced Engine, suitable
      for use on such Airframe and shall have a value and utility at least equal
      to, and be in substantially the same or better condition (and shall have a
      comparable  core value in the LLP stack) as, the Engine  that  should have
      been returned, assuming such Engine which should have been returned was in
      the condition and repair as required by the terms hereof immediately prior
      to  such  required  return;  and  Lessee  will,  at its  own  expense  and
      concurrently  with such  delivery,  furnish Lessor with a bill of sale, in
      form and substance reasonably satisfactory to Lessor and Beneficiary,  for
      each such  engine  and with  evidence  of  Lessee's  title to such  engine
      (including,  if requested,  an opinion of Lessee's counsel) and shall take
      such other action as Lessor or Beneficiary may reasonably request in order
      that title to such  engine  shall be duly and  properly  vested in Lessor.
      Upon full  compliance  with this Article 13.3 and passage of title to such
      engine to Lessor,  such engine shall be an Engine for all purposes of this
      Lease and Lessor will  transfer to Lessee all  Lessor's  right,  title and
      interest in an Engine  constituting  part of the  Aircraft so returned but
      not  installed on such  Aircraft at the time of such  return,  without any
      representation,  warranty or recourse of any kind  whatsoever,  express or
      implied,  except a warranty  that such  Engine is free and clear of Lessor
      Liens,  defects in title  resulting  from Lessor's acts, and all rights of
      Beneficiary.

13.4  LIENS.

      At  redelivery,  Lessee shall  warrant to Lessor that no Liens (other than
      Lessor  Liens)  exist at that  time on the  Equipment  and that  Lessee is
      current on its  payments  to relevant  authorities  and/or  suppliers  for
      landing,  handling,  fuel  navigation  and other  charges  accrued  by the
      Equipment during the Term of the Lease.

13.5  RECORDS.

      Upon the return of the  Equipment,  Lessee shall deliver to Lessor (i) all
      logs,   manuals,   certificates,   data  and   inspection,   modification,
      maintenance  and overhaul  records  required to be maintained with respect
      thereto  under  applicable  rules  and  regulations  of the  FAA or  other
      governmental  authority having  jurisdiction,  (ii) all logs,  manuals and
      catalogs  included with the Equipment on the Delivery Date  therefor,  and
      (iii) all logs, manuals, certificates, data and inspection,  modification,
      maintenance  and overhaul  records that are required to be maintained with
      respect thereto under the rules and regulations of the FAA;  provided that
      Lessee   will  not  in  any  event  be   required  to  provide  any  logs,
      certificates,  data or  records  of any  type  with  respect  to the  use,
      operation,  repair,  maintenance or overhaul of the Equipment prior to the
      Delivery  Date which were not  provided  to Lessee at the time of Lessee's
      acceptance of the Aircraft hereunder.

13.6  REDELIVERY FUEL.

      Fuel in the tanks of the  Aircraft  at  re-delivery  shall be  recorded in
      Appendix A to Lease  Supplement  No. 2. At redelivery of the Aircraft,  if
      there is more or less fuel in the tanks than at delivery, Lessee (if less)
      or Beneficiary  (if more) will pay for the difference at the price of fuel
      at the re-delivery location.

13.7  INDEMNITY.

      The Lessee shall  indemnify  and hold  harmless the  Indemnitees  from and
      against any and all liabilities,  damages and losses  (including costs and
      expenses  incidental  thereto) arising by reason of death or injury to any
      observer  or  employee  of the  Lessee,  arising  out  of,  or in any  way
      connected  with the  demonstration  flight and  inspection of the Aircraft
      conducted  pursuant to Exhibit "E" hereto or the ferry flight set forth in
      Article 13.1.

      The Lessor shall  indemnify  and hold harmless the Lessee from and against
      any and all liabilities,  damages and losses (including costs and expenses
      incidental  thereto)  arising by reason of death or injury to any observer
      or employee of the Lessor or any Indemnitee  arising out of, or in any way
      connected  with the  demonstration  flight and  inspection of the Aircraft
      conducted  pursuant to Exhibit "E" hereto or the ferry flight set forth in
      Article 13.1.

      judgment,  decree or order of any court or any order, rule,  regulation of

ARTICLE 15.  REMEDIES

      Upon the  occurrence  of any  Event of  Default  under the  provisions  of
Article  14.1  (f)  or  (g),  all of  Lessee's  rights  hereunder  in and to the
Equipment  shall  automatically  terminate.  Upon the occurrence of any Event of
Default under any other  provision of Article 14, and at any time  thereafter so
long as the same shall be  continuing,  Lessor may, at its option,  declare this
Lease to be in default  and at any time  thereafter,  Lessor may, in addition to
any other remedies provided herein or by applicable law, exercise one or more of
the following  remedies  with respect to the  Equipment or any part thereof,  as
Lessor in its sole discretion shall elect:

(a)   Demand that Lessee, and Lessee shall upon the written demand of Lessor and
      at Lessee's expense, return promptly to Lessor the Equipment as Lessor may
      specify  in the  manner  and  condition  required  by,  and  otherwise  in
      accordance  with all of the provisions  of, Article 13 hereof  (including,
      without  limitation,  the return of all Records) as if the Equipment  were
      being returned at the end of the Term therefor;  or Lessor, at its option,
      may enter  upon the  premises  where all or any part of the  Equipment  is
      located and take  immediate  possession  of and remove the same  (together
      with any  engine  which is not an  Engine  but which is  installed  on the
      Airframe,  subject to all of the rights of the  owner,  lessor,  lienor or
      secured party of such engine,  provided,  however, that such Airframe with
      an engine  (which is not an Engine)  installed  thereon  may be flown to a
      location  within the continental  United States,  and such engine shall be
      held for the account of any such owner,  lessor,  lienor or secured  party
      or, if owned by Lessee,  may, at the option of Lessor,  be exchanged  with
      Lessee for an Engine in accordance with the terms of Article 13 hereof) by
      summary proceedings or otherwise, all without liability accruing to Lessor
      for or by reason of such entry or taking of  possession,  whether  for the
      restoration of damage to property caused by such taking or otherwise;

(b)   Whether or not Lessor shall have  exercised,  or shall  thereafter  at any
      time exercise,  any of its rights under  paragraph (a) above,  Lessor,  by
      written notice to Lessee specifying a payment date, may demand that Lessee
      pay to Beneficiary,  and Lessee shall pay to  Beneficiary,  on the payment
      date specified in such notice, as liquidated damages for loss of a bargain
      and not as a penalty (in lieu of the Basic Rent for the  Equipment due for
      the  period  commencing  after  the date  specified  for  payment  in such
      notice),  any accrued but unpaid  Basic Rent for such  Aircraft due to and
      including the payment date specified in such notice,  plus an amount equal
      to the excess of (i) the  aggregate  unpaid  Basic Rent for the  Equipment
      which would otherwise have accrued over the remainder of the Term therefor
      but for the Event of Default,  discounted  monthly to present  value as of
      the payment  date  specified  in such notice at 7% per annum over (ii) the
      Fair Rental Value of the Aircraft for the remainder of the Term discounted
      to present  value at the same rate.  The amounts  specified in such notice
      shall  continue to bear  interest at the  Incentive  Rate from the payment
      date specified in said notice until payment is made;

(c)  In the event Lessor  shall have relet the  Equipment,  Lessor,  in lieu of
      exercising  its  rights  under  paragraph  (b) above  with  respect to the
      Equipment  may, if it shall so elect,  demand that Lessee pay  Beneficiary
      and Lessee  shall pay  Beneficiary,  as  liquidated  damages for loss of a
      bargain and not as a penalty (in lieu of the Basic Rent for the  Equipment
      due for the period commencing after the date of reletting) any accrued but
      unpaid Basic Rent for the  Equipment  due up to and  including the date of
      reletting or sale plus the excess of: (i) the aggregate  unpaid Basic Rent
      for the  Equipment  which  would  otherwise  have become due over the Term
      therefor  discounted  monthly to present value as of the date of reletting
      at 7% per annum over (ii) the  aggregate  basic rental  payments to become
      due under the reletting  from the date of such  reletting to the date upon
      which the Term would have  expired but for  Lessee's  default,  discounted
      monthly to present value as of the date of the reletting at 7% per annum;

(d)   Proceed by appropriate  court action or actions to enforce  performance by
      Lessee of the  applicable  covenants of this Lease and to recover  damages
      for the breach hereof;

(e)   Terminate  this  Lease  as  to  any  or  all  items  of  Equipment,  which
      termination shall be effective immediately upon Lessor having given notice
      of termination to Lessee, whereupon Lessee's right to possess and use such
      items of Equipment shall immediately cease.

Except as otherwise specifically provided above, Lessee shall also be liable for
all unpaid Rent due hereunder before, during or after the exercise of any of the
foregoing remedies with respect thereto, including all technical and remarketing
expenses,  legal fees and other costs and  expenses  incurred  by Lessor  and/or
Beneficiary  by reason of the occurrence of any Event of Default or the exercise
of Lessor's remedies with respect thereto and all costs and expenses incurred in
connection  with the  return of the  Aircraft  in  accordance  with the terms of
Article  13  hereof,   or  in  placing  such   Aircraft  in  the  condition  and
airworthiness as required by such Article.

Except as otherwise  expressly  provided  above,  no remedy  referred to in this
Article  is  intended  to be  exclusive,  but 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.  No express or implied
waiver by Lessor  of any  Event or Event of  Default  shall in any way be, or be
construed to be, a waiver of any future or subsequent Event or Event of Default.

ARTICLE 16.  [Intentionally Omitted]

ARTICLE 17.  LETTER OF CREDIT

      As required by Section 3.3,  Lessee shall  deliver to  Beneficiary  as the
Security  Deposit an irrevocable  standby Letter of Credit ("L/C") in the amount
of $[ ]*.  Such L/C shall be  substantially  in the form of Exhibit H hereto and
otherwise in form and substance and from a bank  satisfactory to Beneficiary and
shall provide,  among other things,  that the L/C is  irrevocable  until 90 days
after  the end of the  Term,  the  L/C may be  drawn  upon by  Beneficiary  upon
presentation to the issuing bank of a certificate of Beneficiary stating that an
Event of Default has occurred and is continuing  under the Lease.  Lessee agrees
that in an Event of Default,  Beneficiary  may, at its option,  immediately draw
under  such L/C and apply the same  towards  any or all  amounts  due under this
Lease,  whether such amounts due  constitute  Basic Rent  payments,  damages for
breach  of  this  Lease  or  other  Rent  payments,  all in  Beneficiary's  sole
discretion.  Partial drawings will be permitted. If the L/C expires prior to the
date set forth  above,  Beneficiary  may draw the L/C in full if Lessee  has not
caused it to be  renewed  prior to the third  Business  Date prior to its expiry
date.

ARTICLE 18.  MISCELLANEOUS

18.1  CONSTRUCTION AND APPLICABLE LAW.

      Any provision of this Lease 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
      such provisions  hereof, and any such prohibition or enforceability in any
      jurisdiction  shall not invalidate or render  unenforceable such provision
      in any other  jurisdiction.  To the extent  permitted by  applicable  law,
      Lessee  hereby  waives any  provision of law which  renders any  provision
      hereof prohibited or unenforceable in any respect. No term or provision of
      this Lease may be changed,  waived,  discharged or terminated  orally, but
      only by an  instrument  in writing  signed by the party  against  whom the
      enforcement  of the change,  waiver,  discharge or  termination is sought.
      This Lease shall  constitute  an  agreement of lease,  and nothing  herein
      shall be construed as conveying to Lessee any right,  title or interest in
      the Aircraft or Engine except as a lessee only. The captions in this Lease
      are for convenience of reference only and shall not define or limit any of
      the terms or  provisions  hereof.  This  Lease  shall in all  respects  be
      governed by, and  construed in accordance  with,  the laws of the State of
      New York, United States of America, including all matters of construction,
      validity  and  performance,  without  regard to the conflict of laws rules

18.3  LESSOR'S RIGHT TO PERFORM FOR LESSEE.

      If Lessee fails to make any payment of  Supplemental  Rent  required to be
      made by it  hereunder  or  fails  to  perform  or  comply  with any of its
      agreements  contained  herein in each case,  beyond any  applicable  grace
      period,  Lessor or Beneficiary may itself,  after such prior  consultation
      with  Lessee as shall be  reasonable  under the  circumstances,  make such
      payment or perform or comply with such  agreement,  and the amount of such
      payment  and the  amount  of the  reasonable  expenses  of  Lessor  and/or
      Beneficiary 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 Incentive Rate, shall be deemed Supplemental Rent,
      payable by Lessee upon demand.

18.4  CORPORATE EXISTENCE; MERGER.

      Lessee will  preserve  and maintain its  corporate  existence  and all its
      rights,  privileges  and  franchises  in every  jurisdiction  in which the
      character of its property or the nature of its business makes licensing or
      qualification necessary. Lessee will not merge or consolidate with or into
      any  person  or  entity  or sell,  lease or  otherwise  dispose  of all or
      substantially  all of its  properties,  unless the  surviving  corporation
      expressly assumes in a manner  reasonably  satisfactory to Beneficiary all
      of Lessee's obligations hereunder.

18.5  QUIET ENJOYMENT.

      Lessor  covenants  that as long as no Event of Default has occurred and is
      continuing,  neither  Lessor nor any person  claiming by, through or under
      Lessor shall interfere during the Lease Term with the use,  possession and
      quiet enjoyment of the Aircraft by the Lessee or the exercise by Lessee of
      its rights and privileges hereunder.

18.6  ASSIGNMENT.

      Except as specifically set forth in Article 5.1, this Lease and all or any
      part of Lessee's rights and obligations hereunder shall not be assigned or
      transferred by Lessee  without  Lessor's  prior written  consent,  and any
      purported  assignment or transfer shall be void. Subject to the foregoing,
      this  Lease  shall  inure  to  the  benefit  of and be  binding  upon  the
      respective successors and assigns of the parties hereto, including but not
      limited  to any  corporation  into which  Lessee  may merge,  or which may
      succeed to all or  substantially  all of the  assets of  Lessee,  and such
      corporation shall expressly assume the liability created hereunder.

      Lessor's and  Beneficiary's  interest in this Lease  Agreement  and in the
      Aircraft and in the trust created under the Trust Agreement are assignable
      and  alienable  by Lessor  and  Beneficiary  in whole but not in part upon
      receipt of  Lessee's  consent  (which  will not be required if an Event of
      Default has occurred  and is  continuing)  which will not be  unreasonably
      withheld or delayed, and upon such assignment Lessor and Beneficiary shall
      be discharged  from all further  obligations  hereunder in respect of such
      interest  or  Equipment  assigned  and the  assignee or  transferee  shall
      succeed  to  all of  Lessor's  and  Beneficiary's  rights,  interests  and
      obligations  in respect  thereof as though such assignee or transferee had
      been the initial owner or lessor,  as the case may be, in respect thereof.
      Lessee shall at Beneficiary's  expense comply with all reasonable requests
      of Lessor and/or  Beneficiary,  their successors and assigns in respect of
      the assignment so long as Lessee's obligations hereunder are not increased
      and Lessee's rights and privileges are not reduced thereby (including,  if
      requested, execution of a lease agreement on terms substantially identical
      to this  Lease  Agreement  substituting  the  name of  such  successor  or
      assignee for Lessor and/or  Beneficiary).  For the avoidance of doubt, the
      foregoing  shall not (i)  restrict  Lessor's  and  Beneficiary's  right to
      finance the  Aircraft  and create a security  interest  therein and in the
      Lease without  Lessee's  consent,  or (ii) change  Lessee's  obligation to
      cooperate as and to the extent provided in Article 11.

18.7  EXPENSES.

      Each party shall bear its own expenses in  connection  with  entering into
      this Lease except that Beneficiary shall be responsible for Lessor's costs
      and expenses and Lessee and Beneficiary  will split FAA counsel's fees and
      expenses evenly.  The prevailing party in any action or proceeding between
      Lessor, Beneficiary and/or Lessee to enforce the terms of this Lease shall
      be  entitled to recover  from the other party all its costs and  expenses,
      including reasonable  attorneys' fees incurred by such prevailing party in
      such action or proceeding.

18.8  SURVIVAL.

      The representations, warranties, indemnities and agreements of the parties
      provided for in this Lease, and each party's obligations under any and all
      provisions  hereof,  shall  survive the  delivery of the  Aircraft and the
      expiration or other  termination  of this Lease and are expressly made for
      the benefit of, and shall be enforceable by the applicable party and their
      respective successors and assigns.

18.9  ENGLISH LANGUAGE.

      All Records  shall be kept and  maintained  in the English  language  with
      respect to entries  made  therein  pertaining  to the  operation,  repair,
      maintenance or overhaul of the Equipment  during the Lease Term. All other
      information, notices, communications,  opinions, reports, records, and the
      like required to be given, kept or maintained by Lessee or to be delivered
      to Lessor hereunder, if not in the English language,  shall be accompanied
      by an English translation;  provided, however, that the English version of
      all such information,  notices,  communications,  opinions,  reports,  and
      records and other  documents,  including  this Lease,  shall govern in the
      event of any conflict with the non-English version thereof.

18.10 JURISDICTION.

      The Lessor,  Beneficiary and Lessee each irrevocably agrees that any state
      or Federal Court in the State of New York shall have  jurisdiction to hear
      and determine any suit, action or proceeding,  and to settle any disputes,
      which may arise out of or in connection  with this Agreement and, for such
      purposes,  irrevocably  submits to the  jurisdiction  of such courts.  The
      Lessor,  Beneficiary and Lessee each (i) irrevocably  waives any objection
      which it might now or  hereafter  have to the  courts  referred  to in the
      above  provisions of this Article being nominated as the forum to hear and
      determine  any suit,  action or  proceeding,  and to settle any  disputes,
      which may arise out of or in connection with this Agreement and agrees not
      to claim that any such court is not a convenient or appropriate  forum and
      (ii)  KNOWINGLY,  VOLUNTARILY AND  INTENTIONALLY  WAIVES ANY RIGHTS IT MAY
      HAVE TO A TRIAL BY JURY IN  RESPECT OF ANY  LITIGATION  BASED  HEREON,  OR
      ARISING  OUT OF,  UNDER,  OR IN  CONNECTION  WITH  THIS  AGREEMENT  OR THE
      TRANSACTIONS  CONTEMPLATED  HEREBY,  OR ANY COURSE OF  CONDUCT,  COURSE OF
      DEALING,  STATEMENTS (WHETHER ORAL OR WRITTEN),  OR ACTIONS OF ANY PARTIES
      HERETO OR THERETO.

      The submission to the  jurisdiction of the courts referred to in the above
      provisions of this Article shall not (and shall not be construed so as to)
      limit the right of the Lessor,  Lessee or Beneficiary to take  proceedings
      against the Lessee,  Lessor or  Beneficiary,  as applicable,  in any other
      court of competent jurisdiction nor shall the taking of proceedings in any
      one or more jurisdictions  preclude the taking of proceedings in any other
      jurisdiction, whether concurrently or not.

      Lessee,  Lessor and  Beneficiary,  each  hereby  appoints  CT  Corporation
      System,  New York,  N.Y., as its agent for service of process  relating to
      any  proceedings  before  the New York  courts  in  connection  with  this
      Agreement  and agrees to maintain a process  agent in New York  throughout
      the Term.  Lessee  agrees to service of process by mail to its address set
      forth herein.

18.11 CURRENCY.

      If for the  purpose of  obtaining  judgment in any court in any country it
      becomes  necessary  to  convert  the  amount due under this Lease into the
      currency  of such  country,  then the  conversion  shall be at the rate of
      exchange  prevailing on the day on which the court judgment is given.  For
      this  purpose,  "rate  of  exchange"  means  the  rate  at  which  Lessor,
      Beneficiary  or Lessee,  as  applicable,  is able on the relevant  date to
      purchase  Dollars with such  currency in such  country.  In the event that
      there is a change in the rate of  exchange  prevailing  between the day on
      which the  judgment  is given and the date of payment  of the amount  due,
      Lessee,  Lessor or Beneficiary,  as applicable,  shall pay such additional
      amount as may be  necessary to ensure that the amount paid on such date is
      the amount in the currency of such country  which,  when  converted at the
      rate of exchange prevailing on the date of payment, is the amount then due
      under this Lease in Dollars. Any amount due from Lessee under this Article
      18.11  shall  be due as a  separate  debt and  shall  not be  affected  by
      judgment being obtained for any other sums due under or in respect of this
      Lease.

18.12 INTEGRATION.

      This Lease Agreement  incorporates and supersedes all prior agreements and
      understandings between the parties hereto including the Letter of Intent.

      This Agreement may not be amended,  waived or modified orally, but only in
      a written supplement hereto signed by the parties hereto.

18.13 COUNTERPARTS.

      This Lease may be  executed  simultaneously  in two or more  counterparts,
      each of which shall be deemed an original, but all of which together shall
      constitute one and the same instrument.

      To the extent  that this  Agreement  constitutes  chattel  paper under the
      Uniform Commercial Code of any relevant jurisdiction, no security interest
      in this Agreement may be perfected except by possession of the counterpart
      marked  "ORIGINAL" and  containing  the executed  receipt on the signature
      page hereof.  Any other  counterpart of this Agreement shall  constitute a
      duplicate but shall not be the chattel paper counterpart.

18.14 BANKRUPTCY - SECTION 1110

      It is the  intention  of the  parties  that the  provisions  of 11  U.S.C.
      Section 1110 or any analogous  section of the Federal  bankruptcy laws, as
      amended from time to time,  shall be  applicable  to the  interests of the
      Lessor and  Beneficiary in the Aircraft and to any right of the Lessor and
      Beneficiary  to take  possession of the Aircraft in  compliance  with this
      Agreement. This Agreement is intended to be a lease for Federal income tax
      purposes.

      flight  shall be flown using  Boeing's  standard  operational  test flight
      procedures.  Upon completion of the test flight,  the  representatives  of
      Lessee and Beneficiary  shall agree in writing upon any  discrepancies  in
      such Aircraft  required to be corrected by  Beneficiary in order to comply
      with the provisions of this Lease and  Beneficiary  shall,  or shall cause
      PAL, to promptly  correct any such  discrepancies.  Lessee may be on board
      for the ferry flight,  but not for the purpose of  discovering  additional
      defects.  There will be no additional test flight  following any work done
      at the Delivery Location and prior to acceptance of the Aircraft; provided
      that  the  Aircraft  will be  flown  at the  Delivery  Location  by PAL or
      Beneficiary to the extent required to prove that any defect  discovered on
      the ferry flight by Beneficiary which requires proving has been corrected.

      the powerplants (engines, nacelles and accessories) in accordance with the
      Engine Maintenance Manual, at Beneficiary's option;

15.   The  Aircraft  (including  the Records and other  related  documents to be
      returned  therewith in  accordance  with  Appendix B hereto) shall be made
      available to  Beneficiary  for ground  inspection  by  Beneficiary  at the
      Redelivery  Location.  The Records will be made available to Lessor's Tech
      Rep at least 15 days prior the date of redelivery.  Such inspection  shall
      commence as soon as Lessee begins its performance of the Redelivery  Check
      referred to in Article 19(a)  hereunder.  Lessee shall remove the Aircraft
      from commercial  service and open the areas of the Aircraft as required to
      perform the checks described in these return  conditions,  and shall allow
      Beneficiary  to accomplish  its  inspection in order to determine that the
      Aircraft  (including  the Records) is in the  condition  required  herein.
      During  such  checks,  Beneficiary  personnel  shall not have the right to
      request  that  adjacent  additional  panels  or areas be  opened  to allow
      further inspection. Lessee, at its own expense, shall promptly correct all
      deficiencies  affecting  airworthiness  and  any  discrepancies  from  the
      condition  required by the  provisions  of this Lease  which are  observed
      during such  inspection and are  communicated in writing by Beneficiary to
      Lessee. All repairs shall be classified as permanent;

16.   The Aircraft shall be test flown by Lessee,  using  qualified  flight test
      personnel,  for not more than one  hundred  twenty  (120)  minutes  in the
      vicinity of the redelivery  location for the purpose of  demonstrating  to
      Beneficiary the satisfactory  operation of the Aircraft and its equipment.
      During such test flight command, care, custody and control of the Aircraft
      shall  at  all  times  remain  with  Lessee.   Up  to  three  (3)  of  the
      Beneficiary's  representatives  (or more if  consented  to by Lessee)  may
      participate in such flight as observers.  Beneficiary's  designated  pilot
      shall occupy either the pilot's or co-pilot's seat during such operational
      test  flight.   Such  flight  shall  be  flown  using  Boeing's   standard
      operational  test flight  procedures.  Upon completion of such operational
      flight testing the representatives of Lessee and Beneficiary participating
      in such  testing  shall agree in writing  upon any  discrepancies  in such
      Aircraft  required to be  corrected  by Lessee in order to comply with the
      provisions  of this  Lease and  Lessee  shall  promptly  correct  any such
      discrepancies.

      All flights pursuant to the clause above shall be made at Lessee's expense
      and Lessee shall pay for or reimburse  Beneficiary  for any costs incurred
      by Beneficiary associated with such flights including, but not limited to,
      costs for fuel,  oil,  airport  fees,  insurance,  take-off/landing  fees,

            requires, in accordance with the Manufacturer's Maintenance Planning
            Document),  immediately  after  removal  from  service  and prior to
            return to Lessor, a "C" Check or, if Lessee's terminology for checks
            or its  approved  maintenance  program has changed  during the Term,
            Lessee's  equivalent of the complete applicable C check. All routine
            and non-routine  maintenance  items will be corrected during the "C"
            check and no carry-over items will exist upon re-delivery;

      b.    the  installed  main  landing gear and nose landing gear shall be in
            good operating condition and shall have at least half-time remaining
            prior to the next  scheduled  removal from the Aircraft for overhaul
            or sampling;

18. The condition of installed systems upon return shall be as follows:

      a.    CONTROLLED COMPONENTS

            Aircraft and engine hour and/or cycle controlled  components at time
            of  redelivery  to Lessor shall have  remaining as a minimum,  3,000
            Flight Hours and/or 1200 Cycles,  whichever is applicable  until the
            next   scheduled   removal  for   overhaul,   test,   inspection  or
            disassembly.  All  components  controlled on a calendar  basis shall
            have remaining,  as a minimum,  twelve (12) months before  scheduled
            removal for testing,  inspection  or overhaul.  Such  hour/cycle  or
            calendar  controlled  components are defined as those components for
            which hours and/or cycles and/or calendar times are controlled under
            the Maintenance Program. However, if a component or part has a life,
            overhaul or check  interval limit that is less than the above stated
            hours, cycles or calendar time limit requirement,  such component or
            part shall have as a minimum 90 per cent of the  interval  remaining
            to removal  for  replacement  or  overhaul.  Lessee will not install
            life-limited  or rotable  components on the Aircraft for the purpose
            of depleting the value of this Aircraft.

      b.    CONDITION OF MONITORED COMPONENTS

            Aircraft and engine  systems,  components  or parts  maintained  "on
            condition"  or  condition  monitored  shall be within  the  relevant
            manufacturer's  specified  or  recommended  limits  with no  adverse
            trends.  Each component,  at all times during the Lease,  shall have
            been maintained and monitored in accordance with the requirements of
            the FAA.

19.   Each of the Engines and each module and part thereof at time of redelivery
      to  Lessor  shall  be in good  operating  condition  and  shall  meet  the
      following requirements:

      a.    TIME SINCE REFURBISHMENT

            Each Engine shall have remaining no less than three thousand (3,000)
            Flight  Hours to its  next  scheduled  shop  visit  pursuant  to the
            manufacturer's engine management program policy recommendation,  and
            shall not meet the return condition if any Engine has remaining less
            than such Flight Hours ;

      b.    LIFE LIMITED PARTS

            Life limited parts shall have  remaining at least 3,000 Cycles until
            next scheduled removal for replacement of life limited parts.

      c.    BOROSCOPE INSPECTION

            Both the hot and  cold  sections  of the  Engines  and APU  shall be
            boroscoped in accordance with Lessee's Approved  Maintenance Program
            and   manufacturer's   recommendations   at   Lessee's   expense  at
            redelivery,  and Lessee will correct all  discrepancies  that exceed
            Manufacturer's maintenance manual limitations at its expense. Lessee
            shall provide  Beneficiary  with a written  report and video tape of
            such  boroscope and Lessor's Tech Rep will be entitled to be present
            at  any  such  boroscope.  Lessee  shall  conduct  a  maximum  power
            assurance  run on each  Engine to ensure that each Engine has an EGT
            temperature  margin of 21 degrees or higher.  Satisfactory  evidence
            shall be provided to  Beneficiary  reflecting  the correction of any
            discrepancies found during such inspection;

      d.    TREND MONITORING

            The Engines shall have been  maintained  and monitored for condition
            in accordance  with Lessee's  approved  Engine  Maintenance  Program
            (EMP); all Engine parameters shall be within the  Manufacturer's and
            Lessee's EMP limits with no adverse trends,  determined  through the
            provision by Lessee of the last 20  monitoring  reports or as agreed
            mutually by Lessee and Beneficiary;

            If the Aircraft  engine  historical and  maintenance  records and/or
            trend monitoring data indicate a rate of acceleration in performance
            deterioration  or oil consumption of any Engine and/or the Auxiliary
            Power Unit (APU) which is higher than normal, Lessee shall, prior to
            return,  correct or cause to be corrected  such  conditions  to meet
            normal manufacturer's tolerances;

20.   The condition of the Auxiliary Power Unit upon return shall be as follows:

      The  installed  APU at the  time of  return  to  Lessor  shall  be in good
      operating condition,  shall have no more than 1,000 Flight Hours since its
      last overhaul,  at the time of return.  If the Flight Hours on the APU are
      more or less than the Flight Hours  accumulated  on the APU since overhaul
      at delivery as set forth in Lease Supplement No. 1 (the "Baseline"), there
      will be a financial adjustment payable by Lessee or Beneficiary in respect
      of the Flight Hours above or below the  Baseline,  and the relevant  party
      shall pay to the other the pro rata portion of the cost of an APU overhaul
      based  on the  cost of the last APU  overhaul  prior to  re-delivery  (the
      "Cost") determined by multiplying the Cost by a fraction, the numerator of
      which is the  number  of  Flight  Hours  on the APU more or less  than the
      Baseline,  and the  denominator  of  which  is the  Flight  Hours  between
      overhauls of the APU;

21.   At redelivery,  if requested by Lessor, Lessee shall return the Aircraft's
      interior  (seats,  lavs and  galleys) to its Delivery  Date  configuration
      unless Beneficiary has previously agreed to accept a revised configuration
      on  return.   If   Beneficiary   has  agreed  to  accept  such  a  revised
      configuration  on return equipment the removed interior items shall become
      the property of Lessee and the replacement items the property of Lessor.

22.   To the  extent  that,  at the time of  redelivery,  the  condition  of the
      Aircraft  and records  does not comply  with the  provisions  hereof,  the
      Lessee at its own expense shall cause such rectification to be carried out
      as soon as possible.  In the event that such rectification  extends beyond
      the end of the Term and provided that unless and until such  rectification
      is  effected  the  Beneficiary  would not be able  immediately  to put the
      Aircraft   into   commercial   operation   in  the   required   redelivery
      configuration,  the Term  shall,  at the  option  of the  Beneficiary,  be
      extended and the provisions of this Agreement  shall remain in force until
      such  rectification has been  accomplished;  provided,  HOWEVER,  that the
      Beneficiary  shall  have the  right,  after the end of the  Term,  to take
      possession of the Aircraft and demand  compensation  for costs  reasonably
      incurred by the  Beneficiary  in  connection  with such  repossession  and
      ensuring compliance with these return conditions.

23.   Upon  completion  of the  operational  test flight  pursuant to Article 18
      hereto and after Lessee has  corrected  the  discrepancies  as required to
      comply with all of the  redelivery  conditions set forth in this Schedule,
      the Aircraft  condition  shall be  technically  accepted by  Beneficiary's
      representatives at the redelivery location by the execution of a technical
      acceptance certificate in the form of Lease Supplement No. 2.

      coverage at no extra expense,  include  confiscation and requisition under
      any order of any Government  Entity of or within the United States for the
      Agreed  Value but in no event  shall the Lessee be  required  to cover the

                  the loss payee shall be the Beneficiary and (c) any loss which
                  exceeds the policy  deductible of U.S.  $750,000 up to but not

                  reinsurers'  liability shall be to make such payments as would
                  have fallen due under the relevant  policy of  reinsurance  if
                  the original insurer had (immediately  before such bankruptcy,
                  insolvency,  liquidation,  dissolution or similar proceedings)
                  discharged   its   obligations  in  full  under  the  original

                  "The  Reinsurers  and the  Reassured  hereby agree that in the
                  event of any valid claim arising hereunder within the original
                  policy coverage limitations and conditions, and written notice
                  of such claim being given to the  Reinsurers  by the  original
                  Assured and/or any Additional  Assured,  then Reinsurers shall
                  in lieu of payment to the Reassured, its successor in interest
                  and assigns pay that portion of any loss due to the Additional
                  Assureds for which Reinsurers would otherwise be liable to pay
                  the  Reassured,  it being  understood and agreed that any such
                  payment by  Reinsurers  directly to said  Additional  Assureds
                  shall fully  discharge and release the Reinsurers from any and
                  all further liability in connection therewith. For the purpose
                  of this  Reinsurance  the above  clause  shall  only  apply in
                  respect  of the  interest  of  Additional  Assureds  under the
                  original  policy.  It  is  mutually  agreed  that  the  rights
                  conferred upon Additional Assureds and Reinsurers by the above
                  clause form an integral  part of the policy.  Agreement to the
                  above shall be subject to Reinsurers reserving their rights to
                  set off  against  any claim  payable  under this  clause,  any
                  outstanding premiums applicable to the Aircraft the subject of
                  the Lease  Agreement.  Such set off shall be first  applied to
                  any financial interest of Lessee in the Aircraft involved. Any
                  payment due under this clause  shall not  contravene  any law,
                  statute or decree of the United States.

                  In the case of liquidation, bankruptcy, dissolution or similar
                  proceedings  of or affecting the  Reinsured,  the  Reinsurers'
                  liability  shall be to make such  payments  hereunder as would
                  have fallen due if the Reinsured had (immediately  before such
                  liquidation,  bankruptcy,  dissolution or similar  proceeding)
                  discharged  its  obligations  in full  under the  Policies  in
                  respect to which the Reinsurance Policies were effected.

          (viii)  contain  a  provision  entitling  Beneficiary  or any  insured
                  party to initiate a claim under any policy in the event of the
                  wrongful refusal or failure of Lessee to do so;

               Delivery is to take place; and

        (d)    the  Lessor  shall  have   executed  and   delivered  the  Lessee
               Documents.

4.7     The conditions specified in Clause 4.6 are inserted for the sole benefit
        of the  Lessee and may be waived in whole or in part and with or without
        conditions by the Lessee.  If any of those  conditions are not satisfied
        on the  Delivery  Date  and  the  Lessee  (in its  absolute  discretion)
        nonetheless  agrees to accept  delivery of the Aircraft from the Lessor,
        the Lessor will ensure that those  outstanding  conditions are fulfilled
        within such period as the Lessee may reasonably require.

5.      DELIVERY AND ACCEPTANCE

5.1     Subject to Clauses 4 and 5.8 hereof,  the Aircraft shall be delivered to
        and  accepted  by  the  Lessee  at  the  Delivery   Location   when  the
        Manufacturer  delivers  the  Aircraft in  compliance  with the  Purchase
        Agreement.  The Lessee  and  Lessor  shall  jointly  determine  when the
        Aircraft has been delivered in accordance  with the Purchase  Agreement,
        as further set out in the Purchase Assignment.  If the Lessee and Lessor
        jointly  determine  that the  Aircraft  does  not  meet  the  conditions
        required  at  delivery  under  the  Purchase  Agreement  or  there  is a
        disagreement between the Lessee and Lessor as to whether such conditions
        have been met,  Clauses 5.7 through 5.8 (as  applicable)  shall  govern.
        Upon such delivery and acceptance,  the Aircraft shall become subject to
        and be governed by this  Agreement,  the Lease Period shall commence and
        the Lessee shall thereupon sign and deliver to the Lessor the Acceptance
        Certificate.  After  Delivery,  the Aircraft and every part thereof will
        be, in every  respect,  at the sole risk of the Lessee who will bear all
        risk of loss,  theft,  damage or  destruction  to the Aircraft  from any
        cause whatsoever.  Prior to Delivery, the risk of loss, theft, damage or
        destruction to the Aircraft shall be borne by the Manufacturer  pursuant
        to the Purchase Agreement.

5.2     The Lessor shall not be responsible for any loss or expense, or any loss
        of  profit,  arising  from any delay in the  delivery  of, or failure to
        deliver,  the  Aircraft to the Lessee under this  Agreement  unless such
        delay or  failure  arises  as a direct  consequence  of the  default  or
        failure of the Lessor to perform its obligations hereunder or to pay the
        advance payments and aircraft price for the Aircraft to the Manufacturer
        when it is obligated to do so under the Purchase  Assignment and (to the
        extent provided in the Purchase Assignment) the Purchase Agreement.

5.3     (a)    The Lessee shall indemnify and hold harmless the Indemnitees from
               and against any and all liabilities,  damages,  losses (including
               costs and expenses incidental thereto) arising by reason of death
               or injury to any observer or any employee of the Lessee,  arising
               out of, or in any way connected with any demonstration flight and
               inspection  of the  Aircraft  conducted  pursuant to the Purchase
               Agreement.

        (b)    The Lessor shall  indemnify  and hold harmless the Lessee and its
               shareholders,   affiliates,   directors,   officers,  agents  and
               employees  from and  against  any and all  liabilities,  damages,
               losses (including costs and expenses  incidental thereto) arising
               by reason of death or injury to any  observer or any  employee of
               the  Lessor  or any  Indemnitee,  arising  out of,  or in any way
               connected  with any  demonstration  flight and  inspection of the
               Aircraft conducted pursuant to the Purchase Agreement.

5.4     (a)    If by reason of a default by the Manufacturer (including, but not
               limited to,  failure to tender the  Aircraft  for delivery in the
               condition required by the Purchase Agreement), the Aircraft shall

<PAGE>

               not  have  been  delivered  to  and  accepted  by the  Lessee  in
               accordance  with Clause 5.1 by August 31, 1997,  (i) the Lessor's
               obligation  contained in this  Agreement to lease the Aircraft to
               the Lessee and the Lessee's obligation to lease the Aircraft from
               the Lessor shall expire and (ii) not later than fifteen (15) days
               after  August 31,  1997,  Lessee  shall repay  Lessor all advance
               payments  theretofore  made  by  Lessor  for  the  Aircraft  plus
               interest  thereon at an  interest  rate of LIBOR plus one percent
               (1.0%) (net of any interest  paid to Lessor by the  Manufacturer)
               from the date of  payment  through  the day  prior to the date of
               repayment  by Lessee  and,  upon  such  repayment,  the  Purchase
               Assignment  shall  terminate.  Concurrent  with  receipt  of  the
               advance  payments  and  interest  as  provided  in the  preceding
               sentence, Lessor shall deliver written notice to the Manufacturer
               and Lessee pursuant to the terms of the Purchase  Assignment that
               such Purchase  Assignment has terminated.  If Lessee fails to pay
               such repayments fully when due, the Purchase Assignment shall not
               terminate and,  notwithstanding  anything to the contrary in this
               Clause 5, Lessor will be entitled to pursue remedies  against the
               Manufacturer  with  respect to the advance  payments  made by it.
               Nothing in this  Clause 5.4 (a) is intended to or shall be deemed
               to waive any rights and  remedies  which either the Lessor or the
               Lessee  may have  against  the  Manufacturer  under the  Purchase
               Assignment or Purchase Agreement.

        (b)    If by reason of a Relevant  Event the  Aircraft  is not leased to
               the Lessee and such  Relevant  Event is or becomes a  Termination
               Event,  the  Lessor's  obligation  to lease the  Aircraft  to the
               Lessee hereunder shall expire and the Lessor shall be entitled to
               accept delivery of the Aircraft from the Manufacturer as provided
               in the  Purchase  Assignment,  in  each  case  without  adversely
               affecting  any  right of  Lessor  to  pursue  remedies  available
               against  Lessee  hereunder,  under the Purchase  Assignment or at
               law.

        (c)    The Lessee agrees to diligently perform its obligations under the
               Purchase   Assignment   and  Purchase   Agreement   and  to  take
               commercially  reasonable  steps  within its  control to cause the
               Aircraft to be  delivered  in May 1997 or as soon  thereafter  as
               possible,  subject,  in all cases,  to the terms of the  Purchase
               Agreement.

        (d)    If by reason of a failure by the Lessor to make advance  payments
               or pay the net aircraft  purchase price to the Manufacturer  when
               the Lessor is  obligated to do so under the terms of the Purchase
               Assignment,  the  Aircraft  is  not  leased  to the  Lessee  when
               tendered by the  Manufacturer  in  accordance  with the  Purchase
               Agreement,  following a return to Lessor of any advance  payments
               previously  made by it,  the  Lessee's  obligation  to lease  the
               Aircraft  from  the  Lessor   hereunder  shall  expire  and  this
               Agreement  and  the  Purchase  Assignment  shall  terminate,  but

<PAGE>

               without  adversely  affecting  any  right of any  party to pursue
               remedies available hereunder, under the Purchase Assignment or at
               law against other parties thereto. Concurrent with receipt of the
               advance  payments as provided in the preceding  sentence,  Lessor
               shall  deliver  written  notice to the  Manufacturer  and  Lessee
               pursuant  to the  terms  of the  Purchase  Assignment  that  such
               Purchase Assignment has terminated.

5.5     (a)    The  Lessee  shall (i)  indemnify  the  Lessor in  respect of any
               reasonable  out-of-pocket costs or expenses,  if any, incurred by
               the Lessor as a  consequence  of any delay in the  delivery of or
               non-delivery of the Aircraft to the Lessee,  or non-acceptance of
               the Aircraft by the Lessee under this Agreement (collectively,  a
               "Delay") and (ii) without  duplication  of any payment made under
               the preceding clause (i), pay the Lessor interest on the advanced
               payments made to the Manufacturer  under the Purchase  Assignment
               as provided in Clause 5.5(b),  in either such case, if and to the
               extent  that such  Delay  arises as a direct  consequence  of the
               failure of the Lessee to perform  its  obligations  hereunder  or
               under the Purchase  Assignment or any Relevant  Event,  provided,
               however,  that nothing in this Clause 5.5 is intended to or shall
               be  deemed to waive any  other  right or remedy  provided  to the
               Lessor in this  Agreement  and in the Purchase  Assignment in the
               event of such failure by the Lessee,  including,  but not limited
               to Clause 5.4(b).

        (b)    The  interest  payable by Lessee  pursuant  to Clause  5.5(a)(ii)
               shall  accrue on a daily basis  beginning on the first day of the
               Delay and ending on the earlier of the day prior to (i)  Delivery
               of the  Aircraft  hereunder  or (ii)  expiration  of the Lessor's
               obligation to lease the Aircraft hereunder pursuant to Clause 5.4
               hereof on the full  amount of the  outstanding  advance  payments
               made by  Lessor at an  interest  rate of LIBOR  plus one  percent
               (1.0%).  Such interest  shall be payable upon the earlier of such
               delivery  or  expiration  and/or if the Delay  exceeds one month,
               monthly.

5.6     (a)    If (i) there is an  Excusable  Delay (as defined in the  Purchase
               Agreement)  and as a result thereof the Aircraft is not delivered
               by August 31,  1997 or (ii) the  Manufacturer  estimates  that by
               reason of an Excusable  Delay, the Aircraft will not be delivered
               until  after  August 31,  1997,  the Lessor may elect,  by notice
               delivered  to the Lessee  and the  Manufacturer,  to require  the
               Lessee to repay  within  fifteen  (15) days of  delivery  of such
               notice all advance  payments  theretofore  made by Lessor for the
               Aircraft plus interest  thereon at an interest rate of LIBOR plus
               one  percent  (1%)  (net  of  any  interest  paid  to  Lessor  by
               Manufacturer)  from the date of payment  through the day prior to
               the date of repayment  by Lessee and,  upon such  repayment,  the
               Purchase  Assignment shall terminate and the Lessor's  obligation
               to  lease  the  Aircraft  to  Lessee   hereunder   shall  expire.
               Concurrent  with receipt of the advance  payments and interest as
               provided in the preceding sentence,  Lessor shall deliver written
               notice to the  Manufacturer  and Lessee  pursuant to the terms of
               the  Purchase   Assignment  that  such  Purchase  Assignment  has
               terminated.
<PAGE>

        (b)    If by reason of an  Excusable  Delay or for any other  reason the
               Aircraft is not delivered by the Manufacturer  under the Purchase
               Agreement by November 30, 1997,  the Lessor may elect,  by notice
               delivered  to the Lessee  and the  Manufacturer,  to require  the
               Lessee to repay  within  fifteen  (15) days of  delivery  of such
               notice all advance  payments  theretofore  made by Lessor for the
               Aircraft plus interest  thereon at an interest rate of LIBOR plus
               one  percent  (1.0%)  (net  of any  interest  paid to  Lessor  by
               Manufacturer)  from the date of payment  through the day prior to
               the date of repayment  by Lessee and,  upon such  repayment,  the
               Purchase  Assignment shall terminate and the Lessor's  obligation
               to  lease  the  aircraft  to  Lessee   hereunder   shall  expire.
               Concurrent  with receipt of the advance  payments and interest as
               provided in the preceding sentence,  Lessor shall deliver written
               notice to the  Manufacturer  and Lessee  pursuant to the terms of
               the  Purchase   Assignment  that  such  Purchase  Assignment  has
               terminated.

        (c)    If  Lessee  fails to repay  the  advance  payments  and  interest
               thereon  when  required  to do so by  Lessor  pursuant  to Clause
               5.6(a) or (b), the Purchase  Assignment  shall not terminate and,
               notwithstanding anything to the contrary in this Clause 5, Lessor
               will be entitled  to pursue  remedies  against the Lessee  and/or
               Manufacturer  with  respect to the advance  payments  made by it.
               Nothing in this  Clause 5.6 is  intended to or shall be deemed to
               waive any rights and  remedies  which the Lessor may have against
               the Lessee and  Manufacturer  under this Agreement,  the Purchase
               Assignment or Purchase Agreement.

5.7     (a)    If the  Manufacturer  tenders the Aircraft for delivery under the
               Purchase  Agreement and the Lessor and Lessee mutually agree that
               the  Aircraft  does not meet the  conditions  required  under the
               Purchase Agreement for such delivery, the Lessee shall not accept
               delivery of the  Aircraft  under the  Purchase  Agreement or this
               Agreement  and,  at its  expense  (except as provided in the last
               sentence  of  this  Clause  5.7),  shall  pursue  diligently  all
               commercially  reasonable actions  (including,  but not limited to
               litigation if necessary) to cause the Manufacturer to deliver the
               Aircraft as soon as practicable in the condition  required by the
               Purchase  Agreement.  The Lessee shall keep the Lessor advised of
               the actions that it is taking to obtain  delivery of the Aircraft
               in the required condition and shall consult with the Lessor prior
               to taking such actions to the extent  practicable.  If the Lessee
               reasonably  elects,  in  the  pursuit  of  remedies  against  the
               Manufacturer, to pursue litigation against the Manufacturer,  the
               parties  shall  mutually  agree on an  equitable  sharing  of the
               expenses of such  litigation  (including  prelitigation  expenses
               reasonably incurred,  regardless of whether a lawsuit is actually

<PAGE>

               filed) and any recoveries therefrom, provided, however, that such
               agreement  shall include  whatever  provisions  may be reasonably
               requested by Lessor to ensure that the litigation is conducted by
               Lessee to the reasonable  satisfaction  of Lessor with due regard
               to Lessor's interest in the Aircraft.

        (b)    Notwithstanding anything in Clause 5.7(a) to the contrary, if the
               Lessor's obligation to lease the Aircraft to Lessee expires under
               Clause 5.4(a) or 5.6 hereof,  the Lessor may directly  pursue any
               remedies that it elects to pursue against the Manufacturer  under
               the  Purchase   Assignment   and  Purchase   Agreement.   Without
               limitation of the foregoing, the Lessee and Lessor will cooperate
               with each other to the extent reasonably  requested in any effort
               or pursuit of remedies to obtain  return of the advance  payments
               made by Lessor to the  Manufacturer  and any  reasonable  damages
               sought by the Lessor and/or Lessee with respect thereto.

5.8     (a)    If, following mutual consultation, the Lessee reasonably believes
               that the  Manufacturer  has tendered the Aircraft for delivery in
               the condition  required by the Purchase  Agreement and the Lessor
               disagrees,  the Lessee  shall,  at its  option,  either  elect to
               concur  in  the  Lessor's  position  and  attempt  to  cause  the
               Manufacturer to deliver the Aircraft as provided in Clause 5.7 or
               accept delivery of the Aircraft under the Purchase  Agreement and
               this  Agreement,  in which case Clause 5.8(b) shall apply. If the
               Lessee  accepts  delivery  of the  Aircraft  as  provided  in the
               preceding  sentence,  subject  to  satisfaction  or waiver of the
               conditions  in Clause 4 (other  than Clause  4.3(a)),  the Lessor
               shall pay the aircraft  price to the  Manufacturer  and lease the
               Aircraft to the Lessee under this Agreement.

        (b)    If the Lessee elects to accept delivery of the Aircraft under the
               circumstances  described  in Clause  5.8(a),  the Lessor shall be
               entitled  to  require  that  a   determination   be  made  by  an
               arbitration  panel  as  to  (i)  whether  the  Aircraft  met  the
               conditions  required  by  the  Purchase  Agreement  when  it  was
               accepted  for  delivery by the Lessee and (ii) if not, the amount
               by which the value of the  Aircraft was  diminished  by virtue of
               its  deficient   condition  (the   "Deficiency   Amount").   Such
               determination shall be obtained by arbitration in the City of New
               York,  pursuant  to the  rules  then  obtaining  of the  American
               Arbitration  Association or any written agreement of the parties.
               Such  determination  shall  be  rendered  by  a  panel  of  three
               arbitrators each of recognized  expertise in aircraft  valuation,
               one  arbitrator  to be chosen by each of the  Lessor  and  Lessee
               within twenty (20) days of written  request  therefore being made
               by the Lessor to the Lessee and the third arbitrator to be chosen
               by the other two arbitrators within ten (10) days thereafter.  If
               the  arbitration  panel  decides that the Aircraft was not in the
               condition required by the Purchase Agreement when accepted by the
               Lessee  and  that the  Deficiency  Amount  is $[ ]* or more,  the
               Lessee shall pay the Lessor the Deficiency Amount within ten (10)
               days after the  determination  of such amount by the  arbitration

<PAGE>

               panel  and  shall  pay the  Lessor's  reasonable  legal and other
               out-of-pocket  costs  associated  with the  arbitration  promptly
               after the Lessor submits invoices or other reasonable evidence of
               such costs to the Lessee.  If the arbitration  panel decides that
               the  Aircraft  was  in the  condition  required  by the  Purchase
               Agreement  when  accepted  by the  Lessee  or,  if not,  that the
               Deficiency  Amount is less than $[ ]*, the  Lessor  shall pay the
               Lessee's   reasonable   legal  and  other   out-of-pocket   costs
               associated with the arbitration promptly after the Lessee submits
               invoices or other reasonable evidence of such costs to the Lessor
               and the Lessee shall have no  obligation  to pay such  Deficiency
               Amount.

6.      LESSOR'S WARRANTIES AND MANUFACTURER'S WARRANTIES

6.1     The Lessor  warrants that as long as no  Termination  Event has occurred
        and is  continuing,  neither  the  Lessor nor the Head  Lessor,  nor any
        person  claiming  by,  through  or under  Lessor or Head  Lessor,  shall
        interfere  during the Lease  Period with the use,  possession  and quiet
        enjoyment  of the Aircraft  (including,  but not limited to, the Manuals
        and  Technical  Records) by the Lessee or the  exercise by Lessee of its
        rights and privileges hereunder.

6.2     THE LESSEE EXPRESSLY AGREES AND ACKNOWLEDGES THAT, SAVE ONLY AS PROVIDED
        IN CLAUSE 6.1 AND CLAUSE 2.5, NO WARRANTY OR  REPRESENTATION OF ANY KIND
        IS OR HAS BEEN  GIVEN BY OR ON BEHALF OF THE  LESSOR IN  RESPECT  OF THE
        AIRCRAFT OR ANY PART THEREOF AND, ACCORDINGLY,  THE LESSEE CONFIRMS THAT
        IT HAS NOT, IN ENTERING INTO THIS  AGREEMENT,  RELIED ON ANY WARRANTY OR
        REPRESENTATION  BY THE  LESSOR  OR ANY  PERSON ON THE  LESSOR'S  BEHALF,
        EXPRESS OR IMPLIED,  WHETHER  ARISING BY LAW OR OTHERWISE IN RELATION TO
        THE  AIRCRAFT  OR  ANY  PART  THEREOF,  INCLUDING,  WITHOUT  LIMITATION,
        WARRANTIES  OR  REPRESENTATIONS  AS TO THE  DESCRIPTION,  AIRWORTHINESS,
        MERCHANTABILITY,  FITNESS FOR ANY PURPOSE, VALUE,  CONDITION,  DESIGN OR
        OPERATION OF ANY KIND OR NATURE OF THE AIRCRAFT OR ANY PART THEREOF, AND
        THE  BENEFIT OF ANY SUCH  WARRANTY  OR  REPRESENTATION  BY THE LESSOR IS
        HEREBY  IRREVOCABLY  AND  UNCONDITIONALLY  WAIVED BY THE LESSEE.  TO THE
        EXTENT  PERMISSIBLE  UNDER APPLICABLE LAW, THE LESSEE HEREBY ALSO WAIVES
        ANY RIGHTS  WHICH IT MAY HAVE IN TORT IN  RESPECT OF ANY OF THE  MATTERS
        REFERRED TO ABOVE AND  IRREVOCABLY  AGREES THAT THE LESSOR SHALL HAVE NO
        GREATER  LIABILITY  TO LESSEE IN TORT IN RESPECT OF ANY SUCH MATTER THAN
        IT WOULD HAVE IN CONTRACT  AFTER TAKING  ACCOUNT OF ALL OF THE FOREGOING
        EXCLUSIONS.  NO  THIRD  PARTY  MAKING  ANY  REPRESENTATION  OR  WARRANTY
        RELATING TO THE  AIRCRAFT OR ANY PART THEREOF IS THE AGENT OF THE LESSOR
        NOR HAS ANY SUCH  THIRD  PARTY  AUTHORITY  TO BIND THE  LESSOR  THEREBY.

<PAGE>

        NOTWITHSTANDING  ANYTHING  CONTAINED ABOVE,  NOTHING CONTAINED HEREIN IS
        INTENDED  TO  OBVIATE,  REMOVE OR WAIVE ANY RIGHTS OF  WARRANTY OR OTHER
        CLAIMS RELATING  THERETO WHICH THE LESSEE OR THE LESSOR MAY HAVE AGAINST
        THE  MANUFACTURER  OR SUPPLIER OF THE AIRCRAFT  (INCLUDING ANY ENGINE OR
        PART THEREOF) OR ANY THIRD PARTY.

6.3     The Lessor agrees to assign to the Lessee the benefit of all  assignable
        warranties and  indemnities,  product support and  operational  benefits
        given by the  Manufacturer  pursuant to the Purchase  Agreement (as same
        have been assigned to the Lessor pursuant to the Purchase Assignment) or
        supplier  of any  part  of the  Aircraft  as  provided  in the  Purchase
        Assignment.  The Lessee acknowledges that any such assignment is subject
        to the prior written consent of the Manufacturer or supplier of any part
        of the Aircraft  and each party hereto  agrees to execute and deliver to
        the other party such notices of  assignment  of warranties as such other
        party  may  reasonably   request.   The  Lessee  agrees  to  the  extent
        commercially reasonable to pursue by reasonable procedures such warranty
        claims in respect of the Aircraft as to its  knowledge  may arise having
        taken reasonable steps to ascertain such claims and to notify the Lessor
        of all such claims in excess of the Threshold Amount.

6.4     The Lessee agrees to assign or re-assign to the Lessor or its nominee at
        the time of redelivery of the Aircraft or thereafter, the benefit of all
        remaining  warranties and  indemnities,  product support and operational
        benefits  that are given to the Lessee  during  the Lease  Period by the
        Manufacturer  or supplier of any part of the Aircraft and any person who
        has   repaired   the   Aircraft  or  any  part  thereof  to  the  extent
        transferable.

7.      RENT

7.1     During the Lease  Period  the Lessee  shall pay to the Lessor (or to the
        Lessor's  order)  installments  of rent  for  the  Aircraft  monthly  in
        advance, each such instalment being of the amount specified in paragraph
        2 of Letter Agreement No. 1 opposite the relevant Payment Date and being
        payable on such Payment Date.

7.2     The  Lessee's  obligation  to  pay  rent  and  make  other  payments  in
        accordance  with this  Agreement  shall be  absolute  and  unconditional
        irrespective of any contingency  whatsoever  including,  but not limited
        to, (i) any right of set-off, counterclaim, recoupment, defence or other
        right which either  party  hereto may have  against the other,  (ii) any
        unavailability  of the  Aircraft  for  any  reason,  including,  but not
        limited to, any lack or  invalidity  of title or any other defect in the
        title,   airworthiness,   merchantability,   fitness  for  any  purpose,
        condition,  design,  or operation of any kind or nature of the Aircraft,
        or the ineligibility of the Aircraft for any particular use or trade, or
        for  registration  or  documentation  under  the  laws  of any  relevant
        jurisdiction,  or the Total Loss of, or any  damage  to,  the  Aircraft,
        (iii) any failure or delay on the part of either party  hereto,  whether

<PAGE>

       with or without fault on its part,  in performing or complying  with any
        of the  terms or  conditions  of this  Agreement,  (iv) any  insolvency,
        bankruptcy, administration, reorganization, arrangement, readjustment of
        debt, dissolution,  liquidation or similar proceedings by or against the
        Lessor, the Lessee or any permitted  sub-lessee,  or (v) any lack of due
        authorization  of,  or  other  defect  in,  this  Agreement,  excluding,
        however,  any period in which the Lessee cannot operate the Aircraft due
        to a breach by the Lessor of Clause 6.1 hereof.

7.3     In  addition to all other  payments to be made by the Lessee  under this
        Agreement, the Lessee shall pay to the Lessor (or to the Lessor's order)
        an Aircraft  Commitment  Fee in the amount,  and in accordance  with the
        schedule, set forth in paragraph 1 of Letter Agreement No. 1.

               8.     PAYMENTS, INTEREST AND CALCULATIONS

8.1     All payments to be made by the Lessee under this Agreement shall be made
        (unless specifically otherwise provided in this Agreement) without prior
        demand and in full, without any set-off or counterclaim  whatsoever and,
        subject as  provided in Clause  10.3  (Taxation),  free and clear of any
        deductions  or,  to the  extent  provided  in  Clauses  10.2  and  10.3,
        withholdings  in Dollars for value on the day on which payment is due to
        such bank and  account as the Lessor may from time to time notify to the
        Lessee in writing.

8.2     When any payment under this  Agreement  would  otherwise be due on a day
        which is not a Banking Day,  the due date for payment  shall be extended
        to the next  following  Banking Day unless such Banking Day falls in the
        next  calendar  month  in  which  case  payment  shall  be  made  on the
        immediately preceding Banking Day.

8.3     If the Lessee fails to pay any sum payable to any Indemnitee  (including
        without limitation,  any sum payable pursuant to this Clause 8.3) on its
        due date for payment  under this  Agreement the Lessee shall pay to such
        Indemnitee on demand  interest on such sum from the due date through the
        day prior to the date of actual  payment  (as well  after as before  any
        relevant judgment) at the Relevant Rate of Interest.

8.4     All interest under this Agreement shall accrue from day to day and shall
        be  calculated  on the basis of the actual  days  elapsed  and a 365 day
        year.

8.5     Any  certificate  or  determination  of the  Lessor  as to any  rate  of
        interest or any other amount payable under this Agreement  shall, in the
        absence of manifest  error,  be entitled to a rebuttable  presumption of
        correctness.

8.6     If any sum due from the Lessee  under this  Agreement or under any order
        or judgment  given or made in relation  thereto has to be converted from
        the currency  ("the first  currency") in which the same is payable under

<PAGE>

        this  Agreement or under such order or judgment  into  another  currency
        ("the second  currency") for the purpose of (i) making or filing a claim
        or proof against the Lessee,  (ii) obtaining an order or judgment in any
        court or other  tribunal or (iii)  enforcing any order or judgment given
        or made in relation to this  Agreement,  the Lessee shall  indemnify and
        hold  harmless the Lessor from and against any loss suffered as a result
        of any difference between (a) the rate of exchange used for such purpose
        to convert the sum in question  from the first  currency into the second
        currency  and (b) the rate or rates of  exchange at which the Lessor may
        in the ordinary course of business  purchase the first currency with the
        second  currency  upon receipt of a sum paid to it in  satisfaction,  in
        whole or in part,  of any such  order,  judgment,  claim or  proof.  Any
        amount  due from the  Lessee  under  this  Clause  8.6 shall be due as a
        separate debt and shall not be affected by judgment  being  obtained for
        any other sums due under or in respect  of this  Agreement  and the term
        "rate of exchange" includes any premium and costs of exchange payable in
        connection  with the  purchase  of the first  currency  with the  second
        currency.

9.      COSTS AND INDEMNITIES

9.1     The Lessee shall pay  promptly all costs or expenses  incurred by Lessee

               contribution  towards the legal  costs  incurred by the Lessor in
               connection  with the  negotiation  and  preparation of the Lessee
               Documents and the Security Documents;

        (b)    on demand, all out-of-pocket expenses (including reasonable legal
               fees  and  expenses)   reasonably  incurred  by  the  Lessor  and
               Beneficiary in connection  with any amendment or extension of, or
               the  granting  of any waiver or  consent  under any of the Lessee
               Documents or the Security  Documents  requested by the Lessee and
               all out-of-pocket  expenses (including  reasonable legal fees and
               expenses)  reasonably  incurred  by the  Lessor  and  Beneficiary
               resulting from (i) the  enforcement  of, or  preservation  of any
               rights under,  any of the Lessee Documents in any such case after

<PAGE>

               the occurrence and during the continuance of a Termination  Event
               or  (ii)  breach  of  any  representation,   warranty,  covenant,
               agreement,   condition  or  stipulation  by  the  Lessee  therein
               contained.

        All  expenses  payable  pursuant to this Clause 9.2 shall be paid in the
        currency in which the same are incurred.

9.3     The Lessee shall  indemnify and hold harmless the  Indemnitees,  without
        prejudice  to any of the  Indemnitees'  other  rights  under  any of the
        Lessee  Documents,  from and  against  any costs or  expenses  which the
        Lessee  has  agreed  to pay in  any  Lessee  Document  but  which  shall
        nevertheless  be  claimed  from  or  assessed  against  or  paid  by any
        Indemnitee   (after  prior   consultation  with  Lessee  to  the  extent
        practicable  as reasonably  determined  by the Lessor),  and against any
        liability  incurred by any  Indemnitee by reason of any delay or failure
        of the Lessee to pay any such costs or expenses.

9.4     Without  prejudice to the Lessee's  obligations under Clauses 9.1 to 9.3
        inclusive (Costs and Indemnities), the Lessee agrees at all times during
        or  after  the  Lease  Period,   to  indemnify  and  hold  harmless  the
        Indemnitees  from and against all costs,  expenses,  payments,  charges,
        losses, demands, liabilities,  claims, actions, proceedings,  penalties,
        fines, damages, judgements,  orders or other sanctions (in this Clause 9
        together  referred to as "Losses")  which may be incurred by, or made or
        asserted against such Indemnitee at any time:

        (a)    relating to, or arising  directly or  indirectly in any manner or
               for  any  cause  or  reason   whatsoever   out  of,  the  design,
               manufacture,  testing,  delivery,  import, export,  registration,
               ownership,   possession,   control,   use,  operation,   leasing,
               sub-leasing,   insurance,   maintenance,  repair,  refurbishment,
               condition, service, overhaul,  modification,  change, alteration,
               loss, damage, removal, storage, re-delivery, sale or disposal of,
               in or to the  Aircraft,  or  otherwise  in  connection  with  the
               Aircraft,  or relating to loss or destruction of or damage to any
               property,  or death or  injury  of, or other  loss of  whatsoever
               nature suffered by, any person caused by, relating to, or arising
               from or out of (in each case whether  directly or indirectly) any
               of the foregoing matters; or

        (b)    on  the  grounds  that,  as the  result  of  any  alterations  or
               modifications  of the Aircraft,  any Engine or any Part after the
               Delivery Date, any design, article or material in the Aircraft or
               the  operation  or use thereof  constitutes  an  infringement  of
               patent,   intellectual   property   right  or  any  other   right
               whatsoever.

9.5     Any Loss is excluded from Lessee's agreement to  indemnify  under Clause
        9.4 to the extent such Loss:

<PAGE>

        (a)    Is attributable to acts or events occurring after the Aircraft is
               redelivered  to Lessor or its  designee  or to the Head Lessor or
               the Lenders, as the case may be, in compliance with Clause 19 and
               Schedule 4 hereof;

        (b)    Is a Tax, whether or not Lessee is required to indemnify therefor
               under Clause 10 hereof;

        (c)    Arises as a result of a Lessor Encumbrance;

        (d)    Is attributable to the gross negligence or willful  misconduct of
               any  Indemnitee  or the  breach by any  Indemnitee  of any of its
               representations or obligations under any of the Lease Documents;

        (e)    Is a cost or expense  imposed on Lessor or any  Indemnitee by the
               terms of any of the Lessee Documents or incurred by Lessor or any
               Indemnitee in performing its  obligations to Lessee  hereunder or
               thereunder;

        (f)    Consists of a cost, fee or expense arising out of the transfer by
               Lessor  or  transfer  or  acquisition  by any  Indemnitee  of any
               interest in the  Aircraft or Lessee  Documents  at a time when no
               Termination Event has occurred and is continuing;

        (g)    Arises out of or results from the acts of any Indemnitee prior to
               the date of this Agreement;

        (h)    Consists of any cost, fee or other expense incurred in connection
               with  preparing  or  negotiating  any  Lenders  Document  and any
               amendment  to or  restructuring  of any Lenders  Document  unless
               Lessee  has  expressly  agreed to pay such  cost,  fee or expense
               under any Lessee Document or such Lender Document or amendment or
               restructuring  results from the occurrence  and  continuance of a
               Termination Event;

        (i)    With  respect to a Loss  incurred  under Clause  9.5(b) only,  is
               indemnified by the Manufacturer under the Purchase Agreement;

        (j)    With  respect to any  Indemnitee,  arises  from  acts,  events or
               omissions by such  Indemnitee  in such  Indemnitee's  capacity as

               Aircraft or any Part;

        (k)    Consists of costs,  fees or expenses  related to the negotiation,

               financing  or  refinancing  of the Aircraft  (including,  without
               limitation,  the Head Lease) or any Indemnitee's  interest in the
               Trust Estate  established under the Trust Agreement or any action
               or dispute between or among the parties to any Lenders  Document,
               in each case not resulting from the occurrence and continuance of
               a Relevant Event hereunder;

9.6     In the case of any Loss  indemnified by Lessee under Clause 9.4 which is
        covered by a policy of insurance maintained by Lessee pursuant to Clause
        16  and  Schedule  3  of  this   Agreement,   as  a  condition  to  such
        indemnification,  each  Indemnitee  shall  agree to  cooperate  with the
        insurers  in the  exercise  of their  rights to  investigate,  defend or
        compromise  such Loss as may be required to retain the  benefits of such
        insurance with respect to such Loss.

9.7     An  Indemnitee  shall  promptly  notify  Lessee  of any Loss as to which
        indemnification is sought,  provided that failure to provide such notice
        promptly  shall not affect  Lessee's  obligation  to indemnify  any Loss
        hereunder  except to the extent that such failure  materially  adversely
        affects the ability of the Lessee to contest  such Loss.  Subject to the
        rights of insurers  under policies of insurance  maintained  pursuant to
        Section 16 and Schedule 3 this Agreement, Lessee shall have the right to
        contest  and  defend  any  Loss,  in its own  name or in the name of the
        applicable  Indemnitee,  and shall be entitled to assume  responsibility
        for and  control  of the  defense  of any Loss in  respect  of which any
        Indemnitee makes or intends to make a claim against Lessee for indemnity
        pursuant to this Clause 9 (other than a Loss or claim arising out of any
        Relevant Event)  PROVIDED THAT (a) the legal counsel  retained by Lessee
        for such  purpose  is  reasonably  acceptable  to Lessor  and (b) Lessee
        pursues  such  contest  diligently  and in  good  faith  and,  upon  the
        reasonable  request of the  Indemnitee,  provides  the  Indemnitee  with
        reasonable  details of the status of the contest and copies of all legal
        briefs, court filings and, subject to applicable considerations of legal
        privilege,  counsel's  memoranda relevant to such contest;  and provided
        further,  that if Lessee is legally precluded from pursuing such contest
        or  defense  itself  or from  impleading  any  party  which  the  Lessee
        reasonably  believes  is  ultimately  responsible  for such Loss or from
        asserting any defense, cross-claim reasonably deemed required by Lessee,
        the applicable  Indemnitee  shall, upon Lessee's request and at Lessee's
        expense (with respect to  reasonable  out-of-pocket  costs and expenses)
        and if legally able to do so and fully  indemnified by Lessee hereunder,
        diligently and in good faith pursue such contest, defense,  impleader or
        cross-claim  and  provide  Lessee   information  and  documents  thereon
        comparable to that described  above. In the event that (1) a Termination
        Event has occurred and is  continuing  or (2) the Lessee fails to comply
        with the foregoing  requirements in any material respect, the applicable
        Indemnitee  may  assume  responsibility  for and  control  the  relevant
        contest. To the extent Lessee is entitled to defend any claim hereunder,
        the Indemnitee shall cooperate with all reasonable requests of Lessee in

<PAGE>

        connection with such defense.  Subject to the requirements of any policy
        of insurance,  an Indemnitee  may  participate at its own expense in any
        judicial  proceeding  controlled  by Lessee  pursuant  to the  preceding
        provisions,  and such participation shall not constitute a waiver of the
        indemnification provided in Clause 9.4. Except as above provided in this
        Clause 9.7, an  Indemnitee  shall not be required to contest any Loss or
        to assume  responsibility for or control of any judicial proceeding with
        respect thereto.

9.8     (a)    To the extent that a Loss  indemnified by Lessee under Clause 9.4
               is in fact  paid in full by  Lessee  and/or  an  insurer  under a
               policy of insurance  maintained  by Lessee  pursuant to Clause 16
               and Schedule 3 of this Agreement,  Lessee and/or such insurer, as
               the case may be, shall be  subrogated  to the rights and remedies
               of the Indemnitee on whose behalf such Loss was paid with respect
               to the  transaction or event giving rise to such Loss.  Should an
               Indemnitee  receive any refund, in whole or in part, with respect
               to any Loss paid by Lessee  hereunder  and no Relevant  Event has
               occurred  and is  continuing,  it shall  promptly  pay the amount
               refunded  (but not an amount in excess of the  amount  Lessee has
               paid in respect of such Loss plus interest  attributable  thereto
               in an amount  reasonably  determined by the  Indemnitee and in no
               event will the amount  paid by the  Indemnitee  exceed the amount
               refunded  to the  Indemnitee)  over to  Lessee  less  any net tax
               detriment  realized by such Indemnitee as a result of the receipt
               or accrual of such refund  plus any net tax  savings  realized by
               such Indemnitee as a result of such payment. If the Indemnitee is
               later  required  to  repay  all or  part  of  such  refund,  such
               repayment  shall be a Loss and the  Lessee  shall  indemnify  the
               Indemnitee  against  such  Loss in  accordance  with the terms of
               Clause 9.

        (b)    No Indemnitee  shall enter into a settlement or other  compromise
               or consent to a judgment  with  respect to any Loss  without  the
               prior written  consent of the Lessee,  which consent shall not be
               unreasonably  withheld or delayed,  unless such Indemnitee waives
               its rights under this Clause 9 with  respect to such Losses.  The
               entering  into any  such  settlement  or  compromise  or  consent
               without the prior  written  consent of Lessee shall  constitute a
               waiver by such  Indemnitee  of all its rights of  indemnification
               with respect to the Loss which is the subject of such  settlement
               or compromise or consent.

9.9     In the event  Lessee is required to  indemnify  any  Indemnified  Person
        under Clause 9.4, Lessee shall pay to such Indemnified  Person an amount
        which, after deduction of all taxes actually required to be paid by such
        Indemnified  Person in respect of the receipt of such  amount  under the
        applicable laws of any government or taxing  jurisdiction  (after giving
        credit  for any  saving  in  respect  of any  such  taxes by  reason  of
        deductions,  credits or  allowances  related to the  payment of the Loss
        indemnified against and the payment of related taxes), shall be equal to

<PAGE>

        the amount of the indemnification required.

9.10    The general indemnification provisions of Clauses 9.4 through Clause 9.9
        are not intended to waive or supersede  any specific  provisions of this
        Agreement to the extent such provisions apply to any Loss.

9.11    The Lessee's  obligations  under  Clause 9  shall survive the end of the
        Lease Period.

10.     TAXATION

10.1    (a)    Sums  payable  to  the  Indemnitees  by  the  Lessee  under  this
               Agreement  by  way  of  indemnity  or   reimbursement   shall  be
               calculated  on an  after-tax  basis.  Accordingly,  if and to the
               extent that any such sum payable to any  Indemnitee is taxable in
               the hands of such Person (as the  auditors of such Person  acting
               as experts  and not as  arbitrators  shall  certify  from time to
               time)  such sum  shall be  increased  to an amount  which  (after
               subtracting  any Taxes  suffered by such Person in respect of the
               receipt  of  such  amount  and  after  taking  into  account  any
               deduction,  credit or other  benefit for Tax  purposes  for Taxes
               available in the same taxable year as such sum is taxable to such
               Person  in  respect  of  the  discharge  by  such  Person  of any
               corresponding  liability to a third party) shall equal the amount
               which such Person would have  received had the sum payable by the
               Lessee not been taxable in the hands of such  Person.  If the sum
               payable by the Lessee is  initially  paid on the basis that it is
               not taxable in the hands of any Indemnitee and it is subsequently
               determined  to be taxable or vice versa,  subject to the terms of
               Clause 10.9 hereof,  such  adjustment  and payment  shall be made
               between  such  Person  and the  Lessee  as the  auditors  of such
               Indemnitee  (acting  as  experts  and not as  arbitrators)  shall
               certify as appropriate to restore the after-tax  position of such
               Person to that  which it would have been had the  adjustment  not
               been necessary.

        (b)    If  and  to  the  extent  that  any  sum  (the  "indemnity  sum")
               constituting   (directly  or  indirectly)  an  indemnity  to  any
               Indemnitee  but paid by the Lessee to any person  other than such
               Indemnitee,  shall  properly be treated under  applicable  law as
               taxable in the hands of such Indemnitee,  the Lessee shall pay to
               such  Person  such  sum  (the   "compensating   sum")  as  (after
               subtracting  any Taxes  incurred by such Person in respect of the
               compensating  sum and after taking into  account any  deductions,
               credits  and  other  Tax  benefits  currently  available  to such
               Indemnitee in respect of the payment of the indemnity sum to such
               third   person  for  the  benefit  of,  or  on  behalf  of,  such
               Indemnitee)   shall  reimburse  such  Indemnitee  for  any  Taxes
               incurred by it in respect of the indemnity sum.

        (c)    For the purposes of this Clause  10.1(a) a sum shall be deemed to
               be taxable in the hands of an Indemnitee if it is required  under
               applicable  law to be taken into account in computing the taxable

<PAGE>

               profits or gains of such  Indemnitee,  and if so such  Indemnitee
               shall be deemed to have  suffered  Taxes  thereon  at the rate of
               taxation  applicable  to such  Person's  profits or gains for the
               period in which  the  payment  is so  required  to be taken  into
               account for the purposes of such taxation,  and any associated or
               resulting  deduction,  credit  or  other  benefit  to the  extent
               realized  in the  same  taxable  year as the sum  referred  to in
               Clause  10.1(a) or 10.1(b) is deemed to be taxable shall be taken
               into account.  Each Indemnitee shall use good faith in filing its
               Tax returns and in dealing with taxing  authorities to the extent
               required to seek and claim Tax  benefits  which would  reduce the
               amount of any indemnity  payment required pursuant to this Clause
               10, it being understood and agreed,  however,  that no Indemnitee
               will be under any  obligation  to take any such actions which are
               not consistent  with the Tax reporting  practices and policies of
               such Indemnitee without regard to this transaction.

        (d)    If any Indemnitee shall actually recognize (as determined in good
               faith by the relevant  Indemnitee) a tax benefit by reason of any
               Tax paid or indemnified against by Lessee pursuant to this Clause
               10 or a Loss indemnified  against by Lessee pursuant to Clause 9,
               (whether  such tax  benefit  shall be by means of a  foreign  tax
               credit, depreciation or cost recovery deduction or otherwise) not
               otherwise   taken  into  account  in  computing  any  payment  or
               indemnity by Lessee under this Agreement,  such Indemnitee  shall
               pay to Lessee an amount  equal to such tax  benefit  plus any tax
               benefit  recognized as the result of any payment made pursuant to
               this  sentence;  PROVIDED,  that  such  Indemnitee  shall  not be
               required to make any payment  pursuant to this sentence if and so
               as long as  Termination  Event of a monetary  nature has occurred
               and is continuing; provided, FURTHER, that payments to the Lessee
               by an  Indemnitee  hereunder  shall not exceed (i) the  aggregate
               amount  of all  prior  payments  (plus  any  interest  reasonably
               attributable  thereto in an amount  reasonably  determined by the
               Indemnitee) with respect to such Tax or Loss by the Lessee to the
               Indemnitee  LESS (ii) the aggregate  amount of all prior payments
               with respect to such Tax or Loss by the  Indemnitee to the Lessee
               pursuant  to this Clause  10.1(d).  Any Taxes that are imposed on
               any  Indemnitee  as a result  of the  disallowance  or  reduction
               (including  the  expiration  of  any  tax  credit  carryovers  or
               carrybacks  of such  Indemnitee  that  would not  otherwise  have
               expired) of any reduction in Taxes or refund  referred to in this
               Clause  10.1(d),  as to which (and to the extent) such Indemnitee
               has made any  payment to the  Lessee  required  hereby,  shall be
               treated as a Tax for which the Lessee is  obligated  to indemnify
               such  Indemnitee  pursuant to the provisions of Clause 10 without
               regard to the exclusions set forth in Clause 10.4 hereof.

10.2    WITHHOLDING. If at any time any applicable law, regulation or regulatory
        requirement,  or any governmental authority,  monetary agency or central
        bank requires the Lessee to make any deduction or withholding in respect

<PAGE>

        of Taxes from any payment due to the Lessor or the Beneficiary under the
        Lease  Documents as a result of any change  occurring  after the date of
        this Agreement in applicable law, regulation, treaty or ruling:

        (1)    the sum due from the Lessee in respect of such  payment  shall be
               increased  to the  extent  necessary  to ensure  that,  after the
               making of such deduction or withholding, each Indemnitee receives
               on the due date for such payment a net sum equal to the sum which
               it would have received had no such deduction or withholding  been
               required to be made; PROVIDED, HOWEVER, that the Lessee shall not
               be required to pay any such additional  amount to the extent that
               such Tax would not have been  imposed but for (x) Taxes in effect
               on the  date  of a  voluntary  transfer  by a  Indemnitee  of any
               interest  in the  Aircraft or any of the Lease  Documents  (other
               than any such  transfer  that  occurs  after the  occurrence  and
               during the  continuance  of a Termination  Event) which would not
               have  been  imposed  had  such  Indemnitee  not  transferred  its
               interest  in the  Aircraft or the Lease  Documents  or (y) in the
               case of the Beneficiary,  failure to deliver a properly completed
               Internal Revenue Service Form 1001 (or any substitute form) under
               the applicable United States income tax convention (i) initially,
               on or  prior  to the due  date of the  first  payment  due to the
               Lessor under this  Agreement,  or (ii) after the form referred to
               in clause (i) has expired, after a request by the Lessee for such
               form,  unless it shall no longer be entitled to deliver such form
               due to a change in law, regulation ruling or such convention;

        (2)    the Lessee shall pay to the relevant  authority within the period
               for payment  permitted by  applicable  law the full amount of the
               deduction or withholding (including, but without prejudice to the
               generality of the foregoing,  the full amount of any deduction or
               withholding  from any  increased  amount  paid  pursuant  to this
               Clause 10.2); and

        (3)    the Lessee shall furnish to the  appropriate  Indemnitee  written
               evidence of payment to the relevant  authority  within the period
               for payment  permitted by applicable law, of all amounts deducted
               or withheld as aforesaid.

10.3    TAXES INDEMNIFIED. The Lessee agrees to indemnify and hold harmless each
        Indemnitee  against and agrees to protect,  save and keep  harmless each
        Indemnitee  against,  all Taxes that may be imposed upon or with respect
        to any Indemnitee,  the Lessee, this Agreement, the Lease Documents, the
        Aircraft,  the Airframe,  any Engine, or any Part or any interest in any
        of the foregoing, upon, based upon, measured by, in whole or in part, or
        with respect to:

        (a)    the Aircraft,  the Airframe, any Engine, any Part or any interest
               in or with respect to the foregoing;
<PAGE>

        (b)    the   delivery,   location,   ownership,   manufacture,   design,
               importation,  exportation,  transfer of title,  return,  storage,
               leasing,   operation,  use,  maintenance,   repair,   alteration,
               location,  subleasing,  ownership,  purchase, sale, registration,
               presence,  re-registration,  subleasing,  hire, conditional sale,
               delivery,   redelivery,   nondelivery,   acceptance,   rejection,
               transport,  modification,   substitution,  replacement  or  other
               disposition  of or other  action  or event  with  respect  to the
               Aircraft,  the Airframe,  any Engine or Part or any interest with
               respect to the foregoing;

        (c)    rent,  including  all  installments  of rent,  payable under this
               Agreement;

        (d)    this  Agreement  and the other Lease  Documents or  amendments or
               supplements thereto and any other documents  contemplated thereby
               or the transactions  contemplated  thereby or resulting therefrom
               or the  exercise  of any  rights or  remedies  thereunder  or the
               enforcement thereof; or

        (e)    otherwise with respect to or in connection with the  transactions
               contemplated by this Agreement or the other Lease Documents.

10.4    TAXES  EXCLUDED.  The indemnity  provided for in Clause 10.3 above shall
        not apply to, and the  Lessee  shall have no  indemnity  liability  with
        respect to, any of the following:

        (a)    Taxes  (other than Taxes in the nature of sales,  use,  property,
               rental,  value-added,  goods and  services,  transfer or turnover
               taxes or, in the case of Taxes  imposed by any  jurisdiction,  to
               the extent  such Taxes are  required  pursuant to Clause 10.1 for
               the  computation of amounts payable by the Lessee on an after-tax
               basis) on,  based on,  measured by or with  respect to the net or
               gross  income,  capital  or net  worth,  net or  gross  receipts,
               franchises,  excess  profits  or  conduct  of  business  of  such
               Indemnitee (including,  without limitation,  capital gains taxes,
               minimum taxes,  alternative  minimum taxes,  branch profits taxes
               and accumulated earnings taxes) imposed by (A) any federal, state
               or local government, political subdivision or taxing authority in
               the  United  States  other  than (x) any such  Taxes  imposed  by
               withholding  on or with  respect  to amounts  payable  under this
               Agreement by any federal,  state or local  government,  political
               subdivision or taxing authority in the United States by reason of

<PAGE>

               a change of law, regulation, treaty or ruling as in effect on the
               date  hereof and (y) any such Taxes that are imposed by any state
               or local  government,  political  subdivision or taxing authority
               thereof in the United  States  (other than any state in which the
               applicable  Indemnitee is organized,  has its principal  place of
               business  or is  otherwise  subject  to  taxation  as a result of
               transactions  unrelated to the transactions  contemplated  hereby
               (unless such  Indemnitee  would not have been subject to taxation
               by such taxing authority but for leasing  transactions  involving
               aircraft in which the Lessor is the owner or the  Beneficiary  is
               the  owner or  beneficial  owner of such  aircraft)  or any local
               government or political  subdivision  or taxing  authority in any
               such  state) to the extent  that such  Taxes  would not have been
               imposed but for (1) the registration,  operation, location or use
               of  the  Aircraft,  Airframe,  any  Engine  or  any  Part  in the
               jurisdiction  imposing such Tax or (2) the activities or presence
               of any of the Lessee,  any  affiliate of the Lessee or any Person
               in possession of the Aircraft,  Airframe,  any Engine or any Part
               (other than the Lessor or the Beneficiary) (each referred to as a
               "Lessee  Person") in or any payment  under this  Agreement  being
               made by a Lessee Person from the jurisdiction  imposing such Tax,
               (B) any government or taxing  authority of or in any jurisdiction
               (other than the United  States or any  political  subdivision  or
               taxing  authority  thereof or therein)  other than Taxes that are
               imposed as a result of the registration,  operation,  location or
               use of the  Aircraft,  Airframe,  any  Engine or any Part in, the
               existence  of an office,  fixed place of  business  or  permanent
               establishment  of a Lessee  Person  in, a  Lessee  Person  making
               payments from or other  activities or presence of a Lessee Person
               in  the  jurisdiction   imposing  the  Tax,   provided  that  the
               applicable  Indemnitee  is  not  organized,  does  not  have  its
               principal  place of  business  and is not  otherwise  subject  to
               taxation  in such  jurisdiction  as the  result  of  transactions
               unrelated to the  transactions  contemplated  hereby (unless such
               Indemnitee would not have been subject to taxation by such taxing

               foregoing  resulting from a default by such Indemnitee  under any
               secured financing  transaction  relating to the Aircraft (unless,
               in each  preceding  case,  such  sale,  assignment,  transfer  or
               disposition occurs pursuant to the exercise of remedies after the
               occurrence and during the continuance of a Termination Event);

        (c)    Taxes that are imposed on a transferee  from an Indemnitee to the
               extent of the excess of such Taxes imposed under  applicable  law
               in effect on the date of transfer, over the amount of Taxes which
               would have been  imposed  had there not been a sale,  assignment,
  
<PAGE>

            transfer or other  disposition  to such  transferee,  unless such
               sale,  assignment,  transfer or other disposition occurs pursuant
               to an exercise of remedies  hereunder  after a Termination  Event
               has occurred and while such  Termination  Event is continuing (it
               being  understood  and agreed that this Clause  10.4(c) shall not
               apply to the calculation of the amount  necessary for any payment
               required to be made on an after-tax basis);

        (d)    Taxes  imposed in respect of any period after the  expiration  or
               earlier  termination  of this  Agreement in  accordance  with its
               terms,  except to the extent such Taxes are imposed  with respect
               to the  receipt by an  Indemnitee  of any  amounts  due under the
               Lease  Documents  after such  expiration  or  termination  of the
               Lease, it being  understood that the exception from indemnity set
               forth in this  Clause  10.4(d)  shall  not  apply to Taxes to the
               extent such Taxes relate to events  occurring or matters  arising
               prior  to  or  simultaneously  with  the  time  of  the  earliest
               occurrence of the events covered by this Clause 10.4(d);

        (e)    Taxes imposed upon the Lessor that are on, based on,  measured by
               or with  respect to any fees,  commissions  or  compensation  for
               services  rendered by the Lessor in its capacity as trustee under
               the  Trust  Agreement,   or  fees,  commissions  or  compensation
               received by the Head Lessor or any Lender;

        (f)    Without  affecting  the  Lessee's  rights and  obligations  under
               Clauses 10.2 and 10.6,  Taxes for so long as such Taxes are being
               contested  in  accordance  with the  provisions  of  Clause  10.6
               hereof;

        (g)    Taxes  that  would  not  have  been  imposed  with  respect  to a
               Indemnitee but for any failure of such  Indemnitee  (after timely
               written  notice  from  the  Lessee   accompanied  by  a  properly
               completed draft form of any such  requirement  prepared by Lessee
               at  Lessee's  expense,  other than the Form 1001 to be  delivered
               prior to the date the first  payment is due to the  Lessor  under
               this  Agreement)  to  comply  with  certification,   information,
               documentation, reporting or other similar requirements concerning
               the  nationality,   residence,   identity,  connection  with  the
               jurisdiction  imposing such Taxes or any other  matters,  that is
               required by law as a condition  to  exemption or the relief from,
               or  reduction  of,  such Tax (but only if and to the extent  that
               such  compliance  may be  effected  by  such  Indemnitee  without
               materially  increasing such  Indemnitee's risk of exposure to any
               Tax in the  applicable  jurisdiction,  related  expenses or other
               adverse consequences not indemnified by the Lessee hereunder);

        (h)    Taxes to the extent that such Taxes  would not have been  imposed
               on or with respect to a Indemnitee but for the willful misconduct
               or gross negligence of any Indemnitee thereof;
<PAGE>

        (i)    Taxes which an Indemnitee  would be required to contest  pursuant
               to Clause 10.6 and which such Indemnitee has failed to contest as
               and to the extent required by clause 10.6 and any other Taxes for
               which a successful  contest is foreclosed because of such failure
               of the  Indemnitee,  provided that such failure by the Indemnitee
               has a  material  adverse  effect on the  ability of the Lessee to
               contest such Tax or if and to the extent such failure  results in
               an increase in the amount of any penalties, interests or addition
               to such Tax  (unless  any such  failure by an  Indemnitee  is the
               result of a failure  by the  Lessee to  fulfill  its  obligations
               under Clause 10.6);

        (j)    Taxes imposed on any Indemnitee  resulting from such Indemnitee's
               original  purchase  or other  acquisition  of the  Aircraft,  any
               Engine or any Part or any interest in any thereof;

        (k)    Taxes  imposed  with  respect to any period prior to the Delivery
               Date;

        (l)    Taxes  which  have been  included in the cost of the Aircraft; or

        (m)    Taxes, to the extent that (1) such Taxes  constitute  interest or
               penalties  relating to a Tax (but not the underlying Tax) and (2)
               such  interest  or  penalties  result from the failure to file or
               late  filing of any Tax  return by any  Indemnitee,  unless  such
               failure by the  Indemnitee to file or late filing  results from a
               failure of the Lessee to fulfill its obligation under clause 10.7
               or any other provision of this Agreement compliance with which by
               Lessee is  necessary in order for such  Indemnitee  to be able to
               file such Tax return.

10.5    PAYMENTS.  Each Indemnitee  shall promptly forward to Lessee any written
        notice,  bill  or  advice  received  by it  from  any  taxing  authority
        concerning any Tax for which it seeks  indemnification under this clause
        10. The Lessee shall pay any Tax for which it is liable pursuant to this
        Clause 10 directly to the  appropriate  taxing  authority when due or to
        the Indemnitee within 30 days after receipt of a written demand therefor
        from such Indemnitee  accompanied by a written  statement  describing in
        reasonable  detail the Taxes which are the subject of and basis for such
        indemnity and the computation of the amount so payable, but not prior to
        the  later  of (i) in the  case of  Taxes  paid to an  Indemnitee,  five
        Business  Days prior to the date payment of such Taxes is due, or in the
        case of Taxes paid directly to the  appropriate  taxing  authority,  the
        date such  Taxes are due,  in each  case,  provided  Lessee  has  actual
        knowledge  of the date  such  Tax is due or (ii) in the case of  amounts
        which  are  being  contested,  within  30  Business  Days  after a Final

<PAGE>

        Determination  (as  defined  below).  For  purposes of this Clause 10, a
        "Final  Determination"  shall mean (I) a decision,  judgment,  decree or
        other order by any court of competent  jurisdiction that occurs pursuant
        to the provisions of Clause 10.6,  which decision,  judgment,  decree or
        other order has become final and unappealable,  (II) a closing agreement
        or settlement  agreement  entered into in accordance with Clause 10 that
        has  become  binding  and is not  subject  to  further  review or appeal
        (absent fraud,  misrepresentation,  etc.),  or (III) the  termination of
        administrative   proceedings   and  the   expiration  of  the  time  for
        instituting a claim in a court  proceeding,  in each case, in accordance
        with Clause 10.6.

10.6    CONTESTS; REFUNDS. If a written claim is made against any Indemnitee for
        any  Taxes  that the  Lessee  could be  required  to  indemnify  against
        pursuant to this Clause 10, such  Indemnitee  shall promptly  notify the
        Lessee in writing  (and shall take no action with  respect to such claim
        to the extent  reasonably  practicable for a period of 30 days following
        such notice to the  Lessee),  but the failure to give such notice  shall
        not  diminish the Lessee's  obligation  hereunder,  except to the extent
        that the Lessee's  ability to contest such Tax is  materially  adversely
        affected or if and to the extent such failure  results in the imposition
        of or an increase in the amount of any penalties,  interest or additions
        to such Tax. If  requested  by the Lessee in writing,  within 30 days of
        receipt of such notice from the  Indemnitee,  such  Indemnitee  shall in
        good faith contest  (including  pursuing all judicial appeals other than
        appeals to the  United  States  Supreme  Court),  at the  expense of the
        Lessee,  in the name of such Indemnitee (or the Indemnitee,  in its sole
        discretion,  may permit the Lessee,  if  permitted by law, to contest in
        the name of the Lessee or such  Indemnitee) the validity,  applicability
        and  amount  of such  Taxes by (in the  sole  discretion  of the  Person
        conducting such contest) (i) resisting payment thereof,  (ii) not paying
        the same except under  protest,  if protest is necessary and proper,  or
        (iii) if payment shall be made,  seeking a refund thereof in appropriate
        administrative  and  judicial  proceedings;  PROVIDED  that (u) prior to
        taking such action,  the Lessee shall have agreed to pay such Indemnitee
        all  reasonable  out-of-pocket  costs and expenses that such  Indemnitee
        incurs in connection  with and reasonably  allocable to contesting  such
        claim,  including,  without  limitation,  all  reasonable  out-of-pocket
        legal,  accountants' and investigatory  fees and  disbursements,  (v) if
        such contest is to be initiated by the payment of, and the claiming of a
        refund for, such Taxes, then  notwithstanding  Clauses 10.4 or 10.5, the
        Lessee  shall  provide  such  Indemnitee  with  sufficient  funds (on an
        interest-free  basis and at no  additional  net  after-tax  cost to such
        Indemnitee)  to make such payment,  (w) such  proceedings do not involve
        (A) the  likelihood  of the sale,  forfeiture  or loss of the  Aircraft,
        Airframe any Engine or any Part,  unless the Lessee shall have  provided
        security for the Lessee's  obligations under this Clause 10 with respect
        to  such  claim  reasonably  satisfactory  to  such  Indemnitee  and the
        Beneficiary,  or (B) any  material  risk of the  imposition  of criminal
        penalties  arising from the proper conduct of such  proceeding,  (x) the
        Lessee shall have provided to the  Indemnitee an opinion of the Lessee's
        independent tax counsel (such counsel to be reasonably acceptable to the
        Indemnitee) to the effect that a reasonable basis, within the meaning of
        ABA Formal  Opinion  No.  85-352,  exists for such  contest,  and (y) no
        Termination  Event shall have  occurred  and be  continuing,  unless the
        Lessee shall have provided  security for the Lessee's  obligations under
        this  Clause  10  with  respect  to  such  claim  satisfactory  to  such
        Indemnitee.  In any contest  conducted by a Indemnitee,  the  Indemnitee
        shall  consult in good faith with the Lessee  concerning  the method and
        the forum for such  contest  and shall  permit  the Lessee to review and
  
<PAGE>

        comment  upon all written  claims and  submissions,  but the  Indemnitee
        shall have ultimate control over all aspects of such contest. The Lessee
        shall keep the Indemnitee  fully informed as to the nature,  conduct and
        results  of any  contest  conducted  by the  Lessee  in the name of such
        Indemnitee.  Any  Indemnitee  may elect not to contest  pursuant to this
        Clause 10.6,  or to settle any contest,  but such  election to settle or
        not to contest  without the  written  consent of Lessee  (which  consent
        shall not be unreasonably  withheld)  shall  constitute a waiver by such
        Indemnitee  of any right to  indemnification  pursuant to this Clause 10
        with respect to the claim which was the subject of such proposed contest
        or  settlement,  as the  case may be (and  any  other  claim or Tax with
        respect to which a  successful  contest is  foreclosed  as the result of
        such  settlement  or  election  not to  contest)  and, if the Lessee has
        theretofore  provided  such  Indemnitee  with the funds to pay the Taxes
        that are the subject of such proposed contest or settlement, as the case
        may be, such Indemnitee shall promptly repay such funds.

        Notwithstanding  anything  contained in this Clause 10 to the  contrary,
        the Indemnitee shall not be required to contest any claim if the subject
        matter thereof shall be of a continuing nature and shall have previously
        been decided adversely by a court of competent  jurisdiction pursuant to
        the contest provisions of this Clause 10.6, unless there shall have been
        a change in law (or  interpretation  thereof) or a change in facts after
        the date with  respect to which such  previous  contest  shall have been
        decided,  and  the  Indemnitee  shall  have  received,  at the  Lessee's
        expense,  an opinion of independent  tax counsel  selected by the Lessee
        and  reasonably  acceptable  to such  Indemnitee to the effect that as a
        result of such change in law (or interpretation  thereof) or a change in
        facts,  it is more likely than not that the  Indemnitee  will prevail in
        such contest.

        If any Indemnitee  shall obtain a refund or credit of all or any part of
        any Taxes that the Lessee, pursuant to this Clause 10.6, shall have paid
        for or advanced to such  Indemnitee  or for which the Lessee  shall have
        reimbursed such  Indemnitee,  such Indemnitee  shall, at such time as no
        Termination Event shall have occurred and be continuing, promptly pay to
        the Lessee an amount which,  after the  subtraction of the amount of any
        further net tax savings actually realized by such Indemnitee as a result
        of the payment  under this  paragraph,  and the  addition of any net tax
        detriment  realized  by such  Indemnitee  as a result of the  receipt or
        accrual of such  refund  and any  interest  received  or accrued by such
        Indemnitee  on such  refund,  is equal to the  amount of such  refund or
        credit,  plus  any  interest  actually  received  or  credited  by  such
        Indemnitee on such refund or credit that is fairly  attributable  to any
        Taxes paid by the Lessee to or for such  Indemnitee;  PROVIDED that such
        Indemnitee  shall not be  obligated  to make any  payment  to the Lessee
        pursuant to this  sentence  (other than on account of interest  actually
        received  or  credited)  to the extent  that the amount of such  payment
        would exceed (x) the amount of all prior  payments made by the Lessee to
        such  Indemnitee  pursuant  to this Clause 10 less (y) the amount of all
        prior payments by such Indemnitee to the Lessee (other than that portion

<PAGE>

        of  such  payments  attributable  to  interest  payable  to  the  Lessee
        hereunder)  pursuant  to this  Clause 10 (and the  amount of any  excess
        described  in this  proviso  shall  reduce PRO TANTO the amount that the
        Lessee is  subsequently  obligated  to pay  pursuant  to this  Clause 10
        hereof).  If it is later determined that the Indemnitee was not entitled
        to such refund and such refund would not otherwise  have been  available
        as a credit against a tax liability of such  Indemnitee not  indemnified
        by the Lessee  hereunder,  the  portion of such  refund  that is repaid,
        recaptured or  disallowed  will be treated as Taxes for which the Lessee
        must indemnify the Indemnitee  pursuant to this Clause 10 without regard
        to Clause 10.4. If the Indemnitee  receives an award of attorney's  fees
        in a contest  for which  Lessee  has paid an  allocable  portion  of the
        contest  expenses,   such  Indemnitee  shall  pay  to  Lessee  the  same
        proportion   of  the  amount  of  such  award  as  the  amount  of  such
        Indemnitee's  attorney's  fees paid or reimbursed by Lessee bears to the
        total amount of the attorneys' fees actually  incurred by the Indemnitee
        in conducting such contest.

10.7    REPORTS.  The  Lessee  will  provide  (at  the  Lessee's  expense)  such
        information as is within its control and reasonably requested in writing
        by an Indemnitee that is required or reasonably necessary to enable such
        Indemnitee to fulfill its tax filing,  audit or litigation  requirements
        with respect to the transactions contemplated by the Lease Documents. In
        case any  report,  return or  statement  is required to be made or filed
        with respect to Taxes for which the Lessee has an  indemnity  obligation
        under this Clause 10, the Lessee shall promptly notify the Indemnitee of
        such requirement and shall take the appropriate  action specified in the
        next  succeeding  sentence,  PROVIDED  that such  Indemnitee  shall have
        furnished the Lessee at the Lessee's expense (with respect to reasonable
        out-of-pocket  costs and expenses only) with such information  requested
        by the  Lessee,  not within the  control  of the  Lessee,  as is in such
        Indemnitee's control reasonably necessary to file such report, return or
        statement.  The Lessee shall  either (i) to the extent  permitted by law
        (except for any such  report,  return or  statement  which the  affected
        Indemnitee  has  notified  the Lessee  that such  Indemnitee  intends to
        prepare and file in its own name) or  required  by law,  file in its own
        name any report,  return or statement  required to be filed with respect
        to Taxes for which the Lessee  has an  indemnity  obligation  under this
        Clause  10,  so as to show the  beneficial  ownership  of the  Aircraft,
        Airframe and Parts in the  Beneficiary and furnish the Indemnitee with a
        copy of such report, return or statement, (ii) where such report, return
        or  statement  is  required  to be in  the  name  of or  filed  by  such
        Indemnitee or the Indemnitee otherwise requests that such report, return
        or  statement  be filed in its name,  if  permitted  by  applicable  law
        prepare and deliver such report,  return or statement  (in each case, at
        the  expense of the Lessee  (with  respect to  reasonable  out-of-pocket
        costs and expenses  only)) to the  Indemnitee in such manner as shall be
        reasonably satisfactory to the Indemnitee within a reasonable time prior
        to the time such  report,  return or statement is to be filed (but in no
        event  later than  fifteen  (15) days prior to the due date  thereof) or

<PAGE>

        (iii)  where such  report,  return or  statement  is required to reflect
        items in addition to Taxes imposed on or indemnified  against under this
        Clause 10 as determined by such Indemnitee, provide such Indemnitee with
        information  with  respect to such  indemnified  Taxes  within  Lessee's
        control  and  required  for the  completion  of such  report,  return or
        statement  within a reasonable  time,  sufficient to permit such report,
        return or statement  to be properly  made and timely  filed.  Nothing in
        this Agreement  shall require the Lessee or an Indemnitee to violate any
        law, regulation or administrative pronouncement of any taxing authority.

10.8    FORMS. Each Indemnitee agrees to furnish from time to time to the Lessee
        or to such other  person as the Lessee may  designate,  at the  Lessee's
        written  request  and  expense  (limited  to  reasonable   out-of-pocket
        expenses of such Indemnitee),  such duly executed and properly completed
        forms or other documentation as may be necessary or appropriate in order
        to claim any reduction of or exemption from any withholding or other Tax
        which the Lessee may be required to  indemnify  against  hereunder  (but
        only if and to the extent  such (x)  Indemnitee  is legally  entitled to
        furnish  such forms or other  documentation  and (y) such forms or other
        documentation may be filed by such Indemnitee  without the imposition of
        any Tax or related expense not indemnified by the Lessee hereunder).  If
        and to the extent that an  Indemnitee  fails to file or provide any such
        form or other  documentation  and as a  result  thereof  either  (i) Tax
        withholding  is required at a rate which is higher than that which would
        have been applicable had such return,  statement or other  documentation
        been filed or provided or (ii) Tax  withholding  is required which would
        not have been required had such form or other  documentation  been filed
        or provided, Lessee's obligation to make the increased payment otherwise
        required by Clause  10.2(a)  hereof shall be limited to the amount which
        would have been required if such  Indemnitee  had filed or provided such
        form or other documentation.

10.9    VERIFICATION.  At  the  Lessee's  written  request,  the  amount  of any
        indemnity  payment by the Lessee to any  Indemnitee or any payment by an
        Indemnitee  to the Lessee  pursuant to Clause 10 shall be reviewed by an
        internationally   recognized   independent   accounting   firm  mutually
        acceptable to the  Indemnitee  and the Lessee.  In the case of indemnity
        payments by the Lessee to an  Indemnitee,  such written  request must be
        received  within ninety (90) days of receipt of the written demand under
        Clause 10.5. In the case of payments by an Indemnitee to the Lessee, (i)
        such  written  request  must be received  within  ninety (90) days after
        payment by an  Indemnitee  of any amounts  due to the Lessee  under this
        Clause  10  (or,  if  later,   ten  (10)  days  after   receipt  of  the
        certification from the Indemnitee's firm of outside auditors,  described
        below,  provided that the Indemnitee's firm of outside auditors receives
        such  request  within  ninety  (90)  days  after  such  payment  by  the
        Indemnitee), and (ii) within such notice period, the Lessee (or its firm
        of  outside  auditors)  has set forth in  writing  to the  Indemnitee  a
        reasonable basis to assert that the amount of the payment was erroneous.
        The Lessee may, at its sole cost and  expense,  request that the firm of
        independent  outside  auditors of the Indemnitee  certify to the firm of
        independent outside auditors of the Lessee the basis for the computation
        of such payment by the Indemnitee; PROVIDED that both auditing firms and
        the  Lessee  agree to  treat  such  matter  on a  confidential  basis in
        accordance with the confidentiality provisions set forth below, and that
        the Lessee will have no right to review or inspect such certification or
        any information referred to therein. The verifying accounting firm shall

<PAGE>

        be asked to verify, after consulting with the Lessee and the Indemnitee,
        whether the  Indemnitee's  computations  are correct,  and to report its
        conclusions  simultaneously to both the Lessee and the Indemnitee.  Each
        Indemnitee and the Lessee hereby agree to provide such  accountants with
        all  information  and  materials  as shall be  reasonably  necessary  or
        desirable  in  connection  herewith.   The  fees  and  expenses  of  the
        accountants in verifying a payment  amount  pursuant to this Clause 10.9
        shall be paid by the Lessee, unless the accountants shall determine that
        the amount  calculated by the Indemnitee is (i) more than 105 percent of
        the  correct  amount in the case of a payment  due from the Lessee to an
        Indemnitee,  or (ii) less than 95 percent of the  correct  amount in the
        case of a payment  made by an  Indemnitee  to the  Lessee.  In all other
        cases,  such fees and expenses of the  accountants  shall be paid by the
        Lessee.   Such   accounting   firm  shall  be   requested  to  make  its
        determination  within 30 days. In the event such  accounting  firm shall
        determine that such  computations  are  incorrect,  then such firm shall
        determine  what  it  believes  to  be  the  correct  computations.   The
        computations  of  the  accounting  firm  shall  be  final,  binding  and
        conclusive upon the Lessee and the  Indemnitee,  as the case may be. Any
        information  provided to such accountants by any Indemnitee shall be and
        remain the  exclusive  property of and shall be deemed by the parties to
        be (and the accountants will confirm in writing in a manner satisfactory
        to the Indemnitee that they will treat such information as) the private,
        proprietary and confidential property of such Indemnitee,  and shall not
        be disclosed by the  accountants to any Person for any purpose,  and all
        such materials  shall be returned to such  Indemnitee.  The Lessee shall
        have no right to  inspect  the  books,  records,  tax  returns  or other
        documents  of or  relating  to the  Indemnitee,  as the case may be. The
        Lessee  and each  Indemnitee  agree  that  the  accounting  firm's  sole
        responsibility  shall be to verify the amount of any  payment,  and that
        matters of  interpretation of the terms of this Agreement are not within
        the scope of such firm's responsibilities.

10.10   SURVIVAL.  The  rights and  obligations  of each  Indemnitee  and of the
        Lessee  under  this  Clause 10 shall  survive  the  expiration  or other
        termination of this Agreement and the other Lease Documents.

               (vii) any damage reports in excess of the Threshold Amount;

        (b)    INFORMATION CONCERNING THE AIRCRAFT

               provide  the  Lessor  as  promptly  as   practicable   with  such
               information  regarding the location,  operation,  use, insurance,
               maintenance  and condition of the Aircraft as the Lessor may from
               time to time reasonably  request in writing,  including,  without
               limitation,  copies of any agreement  relating to the Aircraft in
               the Lessee's possession.  The Lessee will provide the Lessor with
               a forecast of the major  scheduled  maintenance  events  (such as
               Engine scheduled  repairs,  C Checks or their equivalent) so that
               the Lessor may plan to be present during such events;

        (c)    INSPECTION

               throughout  the Lease Period  permit the Lessor and/or its agents
               or representatives to inspect the Aircraft at any reasonable time
               upon  giving  the  Lessee  reasonable  prior  written  notice and
               provide them with  appropriate  temporary access to an office and

               survey  carried out by the Lessor as a result of any  maintenance
               failure by Lessee  constituting a Relevant Event.  All time taken
               in  respect  of such  inspections  shall  form  part of the Lease
               Period. The Lessor shall have no duty or liability  whatsoever to
               carry out or take any  action  arising  out of any such  visit or
               inspection.  Any such  inspections  by the Lessor of the Aircraft
               shall  not  interfere   with  the  Lessee's   commercial   flight
               operations or delay the completion of any maintenance and will be
               relevant to the work being  accomplished  on the  Aircraft at the

<PAGE>

               time of inspection  and any such  inspection by Lessor shall be a
               visual walk-around inspection which shall not include opening any
               panels,  bays  or the  like  or any  disassembly  or  removal  of
               components which are not then opened,  disassembled or removed in
               the course of Lessee's maintenance of the Aircraft at the time of
               such inspection,  provided that such limitations  shall not apply
               to inspections occurring (i) under Clause 19 hereof except to the
               extent  expressly  provided  therein or (ii) within a  reasonable
               time  following a maintenance  failure by Lessee  constituting  a
               Relevant Event;

        (d)    NO OPERATIONAL INTEREST

               not represent in any way that any Indemnitee is carrying goods or
               passengers  on the  Aircraft or engaging in any  operation of the
               Aircraft or caring for,  repairing  or having any  responsibility
               for the condition of the Aircraft;

        (e)    COMPLIANCE WITH INSURANCES

               comply with the terms and conditions of the  Insurances,  and not
               do,  consent  to,  or  permit  any act or  omission  which  would
               invalidate or render  unenforceable  the whole or any part of the
               Insurances;

        (f)    AIR TRAFFIC CONTROL INFORMATION AND THIRD PARTY INFORMATION

               where relevant when the Aircraft is under sublease,  procure that
               the Aviation  Authority,  Eurocontrol  and any other relevant air
               traffic control  authority or airport shall furnish to the Lessor
               upon  the  Lessor's  request  from  time to time,  statements  of
               account of all sums due by the sub-lessee to such  authorities or
               airports in respect of all aircraft  (including,  but not limited
               to, the Aircraft)  operated by the  sub-lessee  and shall provide
               and, if applicable,  procure that any sub-lessee shall provide to
               the Lessor a letter substantially in the form of Schedule 8;

        (g)    STATUS OF THE LESSEE

               not,  without  giving the Lessor  thirty (30) day's prior notice,
               change  its chief  executive  office  (as such term is defined in
               Article  9 of the  Uniform  Commercial  Code as in  effect in the
               State of  Colorado)  from 2864 South  Circle  Drive,  Suite 1100,

               to fall  within the  purview  of Section  1110 of Title 11 of the
               United  Status Code or any  analogous  statute  which may replace
               such statute and then be applicable;

        (i)    CITIZEN OF THE UNITED STATES

               remain a Citizen of the United States.

11.3 The Lessee further undertakes with the Lessor that it will:

        (a)    DISPOSAL AND ENCUMBRANCE OF THE AIRCRAFT

               not  attempt  or hold  itself  out as  having  any power to sell,
               charge,  lease or  otherwise  encumber or dispose of the Aircraft
               (save as provided in Clause 12 (Sub-Leasing)),  nor create, incur
               or suffer to exist any Encumbrance  over the Aircraft (other than
               Permitted Liens);

        (b)    PREVENTION OF ARREST

               not do, and will use its best  reasonable  endeavors  to prevent,
               any act  which  could  reasonably  be  expected  to result in the
               Aircraft being arrested, confiscated, seized, taken in execution,
               impounded,  forfeited, detained in exercise or purported exercise
               of any possessory lien or other claim or otherwise taken from the
               possession  of the Lessee and, if any such arrest,  confiscation,
               seizure, taking, impounding,  forfeiture or detention occurs, the
               Lessee will give the Lessor immediate notice thereof and will use
               its best efforts to procure the prompt release of the Aircraft;

        (c)    NO PLEDGING OF CREDIT

               not pledge nor allow any  operator of the  Aircraft to pledge the
               credit of any Indemnitee for any maintenance,  service,  repairs,
               overhauls of, or modifications  to, or changes or alterations in,
               the Aircraft or for any other purpose whatsoever;

        (d)    PROTECTION OF RIGHTS IN THE AIRCRAFT

               The  Lessee  will do all acts and  things  which the  Lessor  may
               reasonably request to protect and preserve the title,  rights and
               interest of the Head Lessor, the Beneficiary,  the Lessor and the
               Lenders  (and to  protect  or  perfect  their  rights  under  the
               Security   Documents)   to  and  in  the   Aircraft   within  the
               jurisdiction  of any State of Registration or in any territory in
               which the  Aircraft  is or may be based or  operated.  The Lessee
               shall do such acts and things at its own cost and expense  except
               that,  unless a Termination Event has occurred and is continuing,

<PAGE>

               the  Lessor  shall  pay  the  reasonable  out-of-pocket  expenses
               incurred  by Lessee in doing such acts and things to protect  and
               preserve  the  rights  and  interest  of  the  Head  Lessor,  the
               Beneficiary  or the  Lenders.  No action  which may  otherwise be
               required by this Clause 11.3(d) shall deprive Lessee of any right
               or  privilege  or  result  in the  incurrence  by  Lessee  of any
               additional  obligations  except as otherwise  expressly  provided
               herein.

12.     SUB-LEASING

12.1    The Lessee will not at any time,  without the prior  written  consent of
        the  Lessor,  sub-lease,  charter,  hire  or  otherwise  part  with  the
        possession or  operational  control of the Aircraft;  provided that this
        Clause shall not prevent the Lessee from:

        (a)    putting the Aircraft in the  possession of any  qualified  person
               for the purpose of maintenance,  service, repair or overhaul work
               or any modifications, changes or alterations permitted under this
               Agreement being carried out thereon;

        (b)    entering  into and carrying  out any charter,  wet lease or other
               agreement  with  respect to the  Aircraft  on terms  whereby  the
               Aircraft  will at all times be operated  by air crew  employed by
               and subject to the  operational  control of the Lessee;  provided
               that any such  charter or other  agreement  shall be permitted by
               the laws of the Lessee's  Country and shall be subordinate in all
               respects to this  Agreement  and will not in any event be capable
               of extending beyond the end of the Lease Period.

        The consent of the Lessor to any approved  sub-lease to another aircraft
        operator shall not be unreasonably withheld or delayed but may be based,
        among other things, on the criteria that:

        (i)    any such sub-lease does not extend beyond the Lease Term;

        (ii)   any such  sub-lease  does not  allow  such  operator  to take any
               action  that the  Lessee  is not  permitted  to take  under  this
               Agreement,  is  consistent  with the terms of this  Agreement and
               permits discharge of all of the Lessee's  undertakings under this
               Agreement;

        (iii)  any such sub-lease  shall be subject to and subordinate to all of
               the  terms  of  this  Agreement  and  the   Sub-Lessee   signs  a
               subordination and undertaking in favor of the Lessor and the Head
               Lessor;

        (iv)   the  Aircraft  remains  registered  in the State of  Registration
               unless the consent of the Lessor to  re-register  the Aircraft in
               the state where any proposed  Sub-Lessee has its principal  place
               of business has been obtained and the Lessee pays all  reasonable
               out-of-pocket  expenses  incurred  by  Lessor,  Head  Lessor  and
               Lenders  (including,  but not  limited  to legal  fees and filing
               expenses) in connection with such re-registration;
<PAGE>

        (v)    such operator is not subject to proceedings of the type described
               in  clauses   20.1(b),   20.1(i),   20.1(j)  or  20.1(k)  at  the
               commencement of any such sub-lease;

        (vi)   no such  operator  shall have any right to further  sub-lease the
               Aircraft;

        (vii)  the  country in which the  principal  place of  business  of such
               operator is located maintains  diplomatic relations with Ireland,
               Japan,  the United  Kingdom and the United  States of America and
               there are no  hostilities  or any imminent  threat of hostilities
               between such country and the aforementioned countries;

        (viii) the Lessee  shall,  regardless of any sublease  remain  primarily
               liable for all obligations under this Agreement;

               Aircraft  thereunder  together  with  such  financial  and  other
               information in relation to the proposed  Sub-Lessee as the Lessor
               may  reasonably  request and the Lessee  shall  provide  evidence
               reasonably requested by the Lessor of the ability of the proposed

<PAGE>

          of  Airworthiness  with  respect  to the  Aircraft  in the public
               transport  passenger  category  issued by the Aviation  Authority
               (subject to Clause 18) and such  certificates  of  maintenance as
               are required for the Aircraft to be used for the public transport
               of passengers or cargo in the State of Registration;

        (b)    OPERATION AND USE

               (i)  procure that the Aircraft is used,  operated and  controlled
                    in  accordance  with  applicable  laws,  ordinances,  rules,
                    regulations,   orders  or   requirements  of  the  State  of
                    Registration  (and of any country or territory  to, from, in
                    or over which the Aircraft  may be flown) and in  accordance
                    with    applicable    certificates,    licenses,    permits,
                    authorizations  and registrations  relating to the Aircraft,

                    by their terms imposed;

               (ii) use the Aircraft  solely in commercial  or other  operations
                    for which the Lessee is duly  authorized  by the laws of the
                    State of Registration  and/or any jurisdiction to whose laws
                    the  Lessee's  operation  of the Aircraft is subject and the
                    Lessee shall  procure that the Aircraft will not be used for
                    any  purpose  for  which it is not  designed  or  reasonably
                    suited,  or outside the tolerances and limitations for which
                    the  Aircraft  was  designed  (provided  that  any  such use
                    resulting  from a nonrecurring  circumstance  not within the
                    control  of the Lessee  shall not be deemed to violate  this
                    provision)  and so as not to invalidate  any  manufacturer's
                    warranties  and  will be  operated  in  accordance  with the
                    Manuals and Technical  Records.  The Lessee shall, and shall
                    procure  that,  the Aircraft is not used for the carriage of
                    (A)  whole  animals,  living  or dead,  except  in the cargo
                    compartments  according to IATA regulations,  and except for
                    domestic  pets carried in a suitable  container  designed to
                    prevent  the escape of any liquid and to ensure the  welfare
                    of the animal and  handicap  passenger  help  animals in the
                    passenger  cabin,  or  (B)  acids,  toxic  chemicals,  other
                    corrosive materials, explosives, nuclear fuels, waste or any
                    nuclear  assemblies or  components,  except as permitted for
                    passenger aircraft under the "Restriction of Goods Schedule"
                    issued by IATA,  or (C) any other goods,  materials or items
                    which would  reasonably  be expected to cause  damage to the
                    Aircraft  and which would not be  adequately  covered by the
                    Insurances,  and,  save for the  benefit of the  Lessee's or
                    sublessee's  cockpit personnel,  the Lessee shall, and shall
                    procure that,  the Aircraft is not utilized for the purposes
                    of  training,  qualifying  or  re-confirming  the  status of
                    cockpit personnel,  and then only if the use of the Aircraft
                    for such purpose is not reasonably  disproportionate  to the
                    use for such  purpose  of other  Aircraft  of the same  type
                    operated by the Lessee;
<PAGE>

               (iii)  procure that the Aircraft will not be used for any purpose
                      or in any manner not fully covered by the  Insurances,  or
                      outside any geographical  limit imposed by the Insurances,
                      or for any illegal purpose or in an illegal manner;

               (iv)   ensure that the crew and engineers  employed by the Lessee
                      in connection  with the  maintenance  and operation of the
                      Aircraft  shall  have  such  qualifications  and hold such
                      valid  licenses as are required by the Aviation  Authority
                      and all applicable laws and regulations;

               (v)    not cause or permit the  Aircraft to proceed to, or remain
                      at,  any   location   which  is  then  the  subject  of  a
                      prohibition  order (or any  similar  order or  directive),
                      sanctions or restriction by or under the US  International
                      Economic  Emergency  Powers  Act  or  the  United  Nations
                      Security Council;

        (c)    BASE OF OPERATIONS

               except with the prior written consent of the Lessor,  ensure that
               the Aircraft shall be based in and operated from Lessee's Country
               and that it will not be located  outside  Lessee's  Country for a
               period of more than  fourteen (14)  consecutive  days or, in each
               case (if longer),  the term of a permitted  sublease,  charter or
               wet lease or for the time required to accomplish any Major Check,
               repair or overhaul;

        (d)    MAINTENANCE

               ensure that the Aircraft is  maintained,  serviced,  repaired and
               overhauled  by the Lessee or, in the case of Major  Checks by the
               Approved Maintenance  Performer,  in accordance with the Approved
               Maintenance  Programme  and in full  compliance  with  the  tasks
               required by the MPD by properly qualified personnel acceptable to
               the Aviation Authority so as to:

               (i)  keep the Aircraft in good repair,  condition and appearance,
                    airworthy   so  as  to   maintain   the  FAA   airworthiness
                    certificate on the Aircraft (subject to Clause 18), clean by
                    Airline Standards,  in as good operational condition as when
                    delivered to the Lessee on the Delivery Date,  fair wear and
                    tear  excepted  and to at least the same  standard  as other
                    aircraft which it owns or operates, PROVIDED, HOWEVER, that,
                    with respect to inspections and modifications not subject to
                    clause  13.1(d)(ii),  if no Relevant Event has then occurred
                    and is  continuing,  during the last year of the Lease Term,
                    the Lessee shall not be obligated to perform an  alteration,
                    modification  or addition to the Aircraft  solely because it
                    has performed such  modification,  alteration or addition on
                    other  aircraft  which  it owns  or  operates  if (aa)  such
                    modification,   alteration  or  addition  is  not  otherwise

<PAGE>

                    required by the terms of this Clause 13.1(d)(i) or any other
                    provision   of  this   Agreement,   (bb)  such   alteration,
                    modification  or  addition  is not  the  incorporation  of a
                    service bulletin or, if it is such  incorporation,  costs in
                    excess  of $[ ]* in  April  1997  Dollars  and  (cc)  Lessee
                    provides Lessor with written notice as soon as is reasonably
                    practicable but, in any event, not later than 6 (six) months
                    prior to the end of the Lease  Term of its  decision  not to
                    perform any such alteration, modification or addition on the
                    Aircraft;

               (ii) comply with all  airworthiness  directives  or similar alert
                    advisory  requirements   affecting   airworthiness  and  all
                    mandatory    inspection   and   modification    requirements
                    applicable  to the  Aircraft or any Part  issued  during the
                    Lease Term and/or having a compliance  date during the Lease
                    Term or within three  hundred and sixty (360) days after the
                    redelivery  of the  Aircraft  and which are  required by the
                    Aviation  Authority and/or the FAA or by any manufacturer of
                    the Aircraft or any Engine or Part. If the Lessee applies to
                    or  canvasses   the  Aviation   Authority  to  postpone  any
                    compliance  date noted in this Clause and such  postponement
                    would  affect  the  condition  of the  Aircraft  when  it is
                    redelivered under Clause 19 hereof,  then Lessee,  not later
                    than the end of the Lease Term,  shall, if such  application
                    was  granted  by  the  Aviation   Authority  (as  reasonably
                    evidenced in writing to Lessor), pay the out-of-pocket costs
                    to Lessor (as reasonably estimated by Lessor) to comply with
                    such requirement unless such application or canvass (aa) was
                    also  made by other  U.S.  airlines  similarly  situated  to
                    Lessee with respect to Boeing 737-300  aircraft and (bb) was
                    made by Lessee  with  respect  to other  applicable  737-300
                    aircraft operated by Lessee;

               (iii)  comply  with  all  applicable  laws,  ordinances,   rules,
                      regulations,  orders  and  requirements  of the  State  of
                      Registration   and   other   aviation   authorities   with
                      jurisdiction  over the Lessee or the  Aircraft or any Part
                      or to, from, or over which the Aircraft may be flown;

               (iv)   maintain  in  good  standing  a  current   certificate  of
                      airworthiness (in the appropriate  category for the nature
                      of the operations of the Aircraft) for the Aircraft issued
                      by the Aviation  Authority (subject to Clause 18) and will
                      from time to time provide to the Lessor a copy on request;

               (v)    if required by the Aviation Authority,  maintain a current
                      certification as to maintenance  issued by or on behalf of
                      the Aviation Authority in respect of the Aircraft and will

               (vi) maintain,  inspect,  function check,  protect and repair the
                    Aircraft in accordance with the Approved Maintenance Program
                    to the  same  standards,  with the  same  care  and  without
                    discrimination  to other  aircraft  owned or  leased  by the
                    Lessee and perform in  accordance  with the MPD, each of the
                    Structural   Inspection,    Zonal   Inspection,    Corrosion
                    Protection/Prevention  tasks during the Lease Period. In the
                    event  that the  Lessee  operates  a  structural  inspection
                    sampling program in respect of the Aircraft during the Lease
                    Period,   such  program   shall  be  operated   strictly  in
                    accordance  with the MPD.  The Lessee shall  accomplish  all
                    service  bulletins  that the Lessee  generally  incorporates
                    into aircraft in its fleet of Boeing 737 aircraft;

               (vii)  maintain the Aircraft in  accordance  with Part 121 of the
                      FAR and any other Rules and  Regulations of the FAA as may
                      be applicable to passenger  category  aircraft,  except to
                      the  extent  that  they   conflict   with  the  rules  and
                      regulations of the Aviation Authority;

               (viii) remedy any damage or defect  shown to be  required  by any
                      inspection    effected    pursuant   to   Clause   11.2(c)
                      (Inspection)  and as  otherwise  required  by the terms of
                      this Agreement; and

               (ix)   comply with the return conditions referred to in Clause 19
                      (Redelivery)  at the end of the  Lease  Period or when the
                      Aircraft is required to be redelivered  pursuant to Clause
                      21;

        (e)    REPLACEMENT OF ENGINES AND PARTS

               ensure that any Engine or any Part  installed  in the Airframe or
               any  Engine   which  has  become  worn  out,   lost,   destroyed,
               confiscated,  unserviceable, time expired, or otherwise unfit for
               use or  which  the  Lessee  is  required  to  replace  under  any
               provision  of this  Agreement  other than this  Clause  13.(e) is
               promptly  replaced  with an item of the same make and model or an
               improved  or advanced  version  thereof,  of at least  equivalent
               value (having  regard to service  bulletin  modification  status,
               shop visit history  (other than Flight Hours or Cycles since last
               Engine Shop Visit in respect of time on the Engine at such Engine
               Shop Visit),  Engine Life Limited Parts status and component hard
               time life status,  but otherwise  without regard to the hours and
               cycles  on such  replacement  engine or part,  provided  that the
               applicable  credits are  adjusted  as provided in Clause  13.4(d)
               hereof),  which  is  suitable  for  installation  and  use on the
               Airframe  or Engine  without  diminishing  the  value or  utility
               thereof and, if such  replacement  occurs at the end of the Lease
               Period, such replacement engine or part shall meet the applicable
               requirements of Clause 19 and Schedule 4;

               maintaining,  servicing,  repairing,  overhauling  or testing the
               Airframe or such Engine, or making such modifications, changes or
               alterations to the Airframe or such Engine as are permitted under
               this Agreement,  and then only if it is promptly reinstalled,  or
               promptly  replaced or  substituted  by an item complying with the
               provisions of Clause 13.1(e) and 13.1(g);

        (g)    INSTALLATION OF ENGINES AND PARTS

               ensure that,  save in  accordance  with Clause 13.2 and 13.3,  no
               engine is  installed  in the Airframe and no Part is installed in
               the  Airframe  or any  Engine,  whether  by way of  substitution,
               replacement, renewal, mandatory improvement or addition unless it
               meets the  requirements  of Clause 13.3(e) and it is (i) then the
               property of the Head Lessor or the Beneficiary and subject to the
               Mortgage or (ii) is such that on  installation in the Airframe or
               Engine  title  thereto  shall vest in the Head  Lessor and become
               subject to the charge  created by the  Mortgage  but be otherwise
               free from  Encumbrances  (other than Permitted  Liens),  in which
               case the Lessee shall  ensure that there is promptly  recorded in
               the Manuals and Technical Records an  acknowledgement  that title
               thereto  does so vest in the  Head  Lessor  as  aforesaid,  which
               acknowledgement  in the  case of any  Engine  shall  specify  the
               manufacturer's  serial number of the  substitute  or  replacement
               Engine,  and the Lessee shall ensure that as soon as  practicable
               thereafter  a  notification  that  title does so vest in the Head
               Lessor is delivered to the Lessor;

               provisions of this Agreement  and/or on the residual value of the
               Aircraft without the prior written  approval of the Lessor,  such
               approval not to be unreasonably withheld.

13.2    TEMPORARY INSTALLATION OF PARTS

        Provided  that  no   Termination   Event  shall  have  occurred  and  be
        continuing,  the Lessee  shall be  entitled  to install  any part on the
        Airframe  or  any  Engine  by  way  of   substitution   or   replacement
        notwithstanding  that such installation is not in accordance with Clause
        13.1(e) and Clause  13.1(g) if such  substitute or  replacement  part is
        suitable  for  installation  and use on the  Airframe  or Engine and (a)
        there shall not have been available to the Lessee at the time and in the
        place that such part was required to be installed on the Airframe or any
        Engine a substitute or replacement  Part complying with the requirements
        of Clause 13.1(e) and Clause 13.1(g),  and (b) it would have resulted in
        an  unreasonable  disruption of the operation of the Aircraft and/or the
        business of the Lessee as an airline to have grounded the Aircraft until

<PAGE>

        such time as a Part  complying with the  requirements  of Clause 13.1(e)
        and Clause 13.1(g) became  available for installation in the Airframe or
        any Engine,  and (c) as soon as practicable  after  installation  of the
        same on the  Airframe or any Engine,  the Lessee  shall  ensure that any
        such Part not  complying  with the  requirements  of Clause  13.1(e) and
        Clause  13.1(g)  is  removed  and  replaced  or  substituted  by a  Part
        complying with the requirements of Clause 13.1(e) and Clause 13.1(g).

13.3    INTERCHANGE OF ENGINES

        (a)    GENERAL PRINCIPLES

               (i) The  Lessee  shall not at any time  during  the Lease  Period
        remove an Engine from the  Airframe or install any engine  other than an
        Engine  (complying with the provisions of Clause 13.1(e) and 13.1(g)) on
        the Airframe except (aa) for purposes of engine management,  maintenance
        or repairs to an Engine permitted by this Agreement or (bb) as expressly
        permitted by this Clause 13.3.

               (ii) If an Engine is at any time  removed  from the  Airframe for
        purposes of maintenance  or repairs,  the Lessee shall complete the same
        or  procure  that  same  are  completed,  as soon as  practicable  after
        removal.

               (iii) Except in accordance  with Clause  13.3(c) or 13.3(d),  the
        Lessee shall not at any time during the Lease  Period  install a Removed
        Engine on an airframe other than the Airframe.

               (iv) If an Engine is at any time  removed  from the  Airframe for
        any reason whatsoever,  title to such Removed Engine shall remain vested
        in the Head  Lessor  at all  times  (other  than as  provided  in Clause
        13.1(e)  and  Clause  13.1(g)),  subject  to the Head  Lease,  the Trust
        Agreement,  this  Agreement  and the  Mortgagee and the Lessee shall not
        take any steps which may  reasonably be expected to (aa)  jeopardize the
        Head  Lessor's  ownership  rights  in the  Removed  Engine  or (bb) lead
        reasonable  third  parties to  believe  that the  Removed  Engine is the
        property of any person other than the Head Lessor or (cc) create,  incur
        or suffer to exist any Encumbrance other than a Permitted Lien over such
        Removed Engine.

        (b)    TEMPORARY REMOVAL OF ENGINES

               Except as provided in Clause  13.3(c),  if an Engine shall become
        unserviceable at any time or if scheduled maintenance works are required
        to be performed  on such Engine,  the Lessee shall be entitled to remove
        such Engine from the Airframe and to install an engine owned or operated
        by the Lessee and  suitable  for  installation  and use on the  Airframe
        provided that the following conditions are satisfied:
<PAGE>

               (i) it would have resulted in an  unreasonable  disruption of the
        operation  of the  Aircraft  and/or  the  business  of the  Lessee as an
        airline  to have  grounded  the  Aircraft  until  such time as a Removed
        Engine became available for re-installation on the Airframe;

               (ii) the Lessee  shall have  notified  the Lessor prior to or, in
        the case of urgency  as soon as  practicable  after,  the making of such
        substitution; and

               (iii) as soon as practicable  after  installation  of the same on
        the Airframe (and in any event no later than 120 days  thereafter),  the
        Lessee shall move the installed engine and re-install a Removed Engine.

        (c)    POOLING OF ENGINES WITHIN THE LESSEE'S FLEET

               (i) In this Clause  13.3(c),  "Fleet  Aircraft"  means any Boeing
        737-300 aircraft from time to time operated by the Lessee.

               (ii) The  Lessee  shall be  entitled,  so long as no  Termination
        Event shall have  occurred and be  continuing,  to remove an Engine from
        the Airframe and to install on the Airframe an engine provided that:

                      (aa) such  engine is  leased  to the  Lessee  with a Fleet
        Aircraft,  is owned by the Lessee or otherwise  leased to the Lessee and
        is suitable for installation and use on the Airframe;

                      (bb)  the  Removed   Engine  is,   during  the  period  of
        substitution,  either being safely  housed and  sheltered in  accordance
        with  Manufacturer's  recommendations  and this Agreement or repaired or
        maintained in accordance with this Agreement, or is installed on a Fleet
        Aircraft in compliance with Clause 13.3(c)(iii) hereof;

                      (cc) the Lessee  maintains  insurance  cover in accordance
        with this  Agreement  for the  Engine  Agreed  Value in  respect  of the
        Removed  Engine at all times while it is installed on a Fleet  Aircraft;
        and

                      (dd) prior to the  expiration or  termination of the Lease
        Period, such engine is removed from the Airframe and the Removed Engine,
        or,  at the end of the  Lease  Period,  an  Engine  complying  with  the
        provisions of Clause 13.1(e) and 13.1(g), is installed on the Airframe.

               (iii) The  Lessee  will be  entitled,  so long as no  Termination
        Event shall have occurred and be  continuing,  to install an Engine on a
        Fleet Aircraft:

                      (aa)   owned and operated by Lessee free from any Liens;or
<PAGE>

                      (bb)  leased to Lessee on a  long-term  basis and on terms
        whereby Lessee has full operational control of the aircraft or purchased
        by Lessee  subject to a  conditional  sale or other  security  agreement
        PROVIDED  THAT:  (1) the  terms  of any  such  lease,  conditional  sale
        agreement or security interest will not have the effect of impairing the
        title and interests of Lessor as owner and lessor of the Engine; and (2)
        the lessor  under such lease,  the seller  under such  conditional  sale
        agreement or the holder of such security  interest,  as the case may be,
        has  confirmed  and  acknowledged  in  writing,  in form  and  substance
        reasonably satisfactory to Lessor, that it will respect the interests of
        Lessor as owner and  lessor of that  Engine and that it will not seek to
        exercise any rights  whatever in relation  thereto (it being  understood
        that such agreement may be in the form described in Clause  13.3(c)(iv),
        in which case such agreement need not be provided to Lessor).

               (iv) In the event the Lessee shall have  received from the lessor
        or  secured  party of any  Fleet  Aircraft  leased to Lessee or owned by
        Lessee  subject  to a  conditional  sale or other  security  interest  a
        written agreement complying with Clause  13.3(c)(iii)(bb)  hereof (which
        agreement  may be  contained  in the  lease,  conditional  sale or other
        security  interest  covering  such  Fleet  Aircraft)  and such  lease or
        conditional sale or other security interest covering such Fleet Aircraft
        also covers an engine or 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  interest,  Lessor hereby agrees for
        the benefit of such lessor or secured party that Lessor will not acquire
        or claim, as against such lessor or secured party,  any right,  title or
        interest in 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,
        conditional sale or other security  interest and owned by such lessor or
        subject to a security interest in favor of such secured party.

               (d)    POOLING OF ENGINES WITH OTHER OPERATORS

                      the  Lessee  may,  with the prior  written  consent of the
        Lessor (such consent not to be unreasonably withheld) lease, let or hire
        or  charter or  otherwise  part with  possession  of an Engine (on terms
        conferring no more than a  contractual  right against the Lessee but not
        rights against the Engine) pursuant to pooling arrangements to which the
        Lessee is a party and which either:

                      (i)  are  arrangements  involving   responsible,   solvent
        scheduled  Certificated Air Carriers;

                      (ii) do not  contemplate  transfer  of title to any pooled
        Engine (or if title is so  transferred,  such transfer will be deemed an
        event of loss under Clause 13.1(e)); and
<PAGE>

                      (iii) either  provide that  the Lessor (or at the Lessor's
        direction, any of the Indemnitees) will be sole loss payee in respect of
        any loss or  damage to such  Engine  for the  Engine  Agreed  Value,  or
        provide for the Head Lessor to acquire title to a substitute engine free
        from Encumbrances satisfying the conditions set out in Clause 13.1(e) if
        the Engine is a Total Loss.

                    directly  to  the   relevant   maintenance   performer   (as
                    appropriate)  within fifteen (15) Banking Days of receipt of
                    the  documentation   sufficient  to  enable  the  Lessor  to
                    determine the amounts owed as provided in Clause 13.4(e), in
                    the case of Airframe  Maintenance,  to be deducted  from the
                    Airframe  Maintenance  Credit  and,  in the  case of  Engine
                    Maintenance,  from the applicable Engine  Maintenance Credit
                    relating   to  the  Engine  the   subject  of  such   Engine
                    Maintenance  and, in the case of Engine LLP Replacement from
                    the  applicable  Engine LLP  Maintenance  Credit and, in the
                    case of Landing  Gear  Maintenance,  from the  Landing  Gear
                    Maintenance  Credit,  a sum  equal to the  aggregate  amount
                    evidenced by such invoices or receipts,  to the extent there
                    is sufficient credit in such Airframe  Maintenance Credit or
                    relevant  Engine  Maintenance  Credit or relevant Engine LLP
                    Maintenance  Credit or Landing Gear Maintenance  Credit.  To
                    the  extent  that  there  is  insufficient  credit  in  such
                    Airframe  Maintenance  Credit,  relevant Engine  Maintenance
                    Credit or relevant Engine LLP Maintenance  Credit or Landing
                    Gear Maintenance  Credit, the Lessee shall be liable to, and
                    shall   forthwith,   pay  the   shortfall  to  the  relevant
                    maintenance  performer.  Lessor shall have no  obligation to
                    make any  payments or otherwise to account to Lessee for any
                    credits remaining in the aforementioned  maintenance credits
                    at the  expiration or other  termination of the Lease Period
                    except that Lessor  shall pay Lessee an amount  equal to the
                    outstanding  amount of such  credits if the Lease Period has
                    terminated pursuant to Clause 17.4 hereof and the Lessor has
                    received the Agreed Value for the Aircraft.

        (e)     The Lessor  shall not be required to pay moneys to the Lessee or
                directly to the relevant maintenance  performer (as appropriate)
                as provided  for by this Clause 13.4 until such time as it shall
                have received reasonable  documentation adequate to enable it to
                determine  the  amount  to be  paid  (in  which  case,  for  the
                avoidance of doubt, it must pay such amounts  pursuant to Clause
                13.4(d)  within  fifteen  (15)  Banking  Days  thereafter).  The
                documentation  delivered by the Lessee to the Lessor  evidencing
                the  incurring  of expenses  shall  include an  invoice,  a shop
                workscope,  a shop  visit or  maintenance  visit  report  and if
                reasonably requested any additional substantiating data from the
                person that performed such  maintenance  or, if performed by the
                Lessee,   a  statement  of  completion   thereof  together  with
                completed work cards or other documents  requested by the Lessor
                and a  certificate  from  an  authorized  representative  of the
                Lessee that the amounts and other  information set forth in such
                statement  and invoice are  correct.  Any overhaul or other work
                performed  by the  Lessee  or by any  affiliated  or  associated
                company of the Lessee  shall be invoiced at the Lessee's or such
                affiliated  or  associated  company's  actual  cost of  material
                without  mark-up  or profit  and its fully  burdened  labor cost
                capped at 130% of Lessee's  internal  manhour rate of performing
                such  work   without  any  mark-up  or  profit  (as   reasonably
                demonstrated by documentation delivered to Lessor).
<PAGE>

        (f)     If an Engine is replaced as provided in Clauses  13.1(e) and (g)
                hereof,  at the time of such  replacement the applicable  Engine
                Credit and LLP Maintenance Credit will be adjusted either upward
                by payment by Lessee of Engine Maintenance Accrual and/or Engine
                Life Limited Part Accrual with respect of such Engine in amounts
                determined as provided in Clause  13.4(a)  hereof or downward by
                payments by Lessor to Lessee if the amount of the current amount
                of the  credits  is too  high.  Specifically,  the  value of any
                Engine  Maintenance  Accrual Credit will be determined by direct
                comparison of prior Engine Shop Visit  history,  work scopes and
                histories of the  relevant  engines.  The Lessee  shall  provide
                Lessor   with   documentation   adequate,   in  the   reasonable
                determination  of the  Lessor,  to enable  Lessor to verify  the
                amounts of such adjustments.

13.5    The  Lessor  shall  have no  duty to  determine  whether  the  Aircraft,
        Airframe,  Engine or any Part requires  overhaul or  maintenance,  or to
        observe,  or  inspect  the  overhaul  or  maintenance  of the  Aircraft,
        Airframe,  any Engine or any Part,  and the  Lessor  shall not incur any
        liability  or  obligation  to Lessee by  reason  of the  failure  of the
        Aircraft to be properly  overhauled  or  maintained  or by reason of the
        Lessor's election to observe or inspect or not to observe or inspect any
        overhaul or maintenance.

14.     MANUALS AND TECHNICAL RECORDS

14.1    Throughout  the Lease  Period the Lessee shall keep,  and shall  procure
        that  there are kept,  accurate,  complete  and  current  records of all
        flights made by the Aircraft, and of all maintenance and repairs carried
        out to the  Airframe  and each  Engine,  and shall  maintain,  and shall
        procure that there are maintained, all other records, logs and documents
        including,  but not  limited  to,  JAA Form 1 and/or  FAA 8130  Tags and
        repair  or  overhaul  shop  visit  reports  which  are  required  to  be
        maintained  in respect of the  Aircraft by the Aviation  Authority,  and
        shall allow the Lessor and/or its agents or  representatives  to examine
        and take  copies of such  records  at any  reasonable  time upon  giving
        notice to the Lessee.

14.2    The records so kept shall conform with the regulations from time to time
        in force of the  Aviation  Authority,  and with the normal  practices of
        public air transport  operators,  and shall disclose the  whereabouts of
        all Engines and Parts not installed on the Airframe.

14.3    The  records so kept shall be in  English,  shall be part of the Manuals
        and  Technical  Records  and shall be the  property  of the  Lessor  and
        subject to the Mortgage and, at the end of the Lease Period,  the Lessee
        shall deliver the same to the Lessor,  provided that the Lessee shall be
        entitled to make and retain copies thereof.

14.4    The Lessee shall (save as hereinafter provided) keep all the Manuals and
        Technical  Records  on  the  Aircraft  or in  its  possession  or in the
        possession of the Approved Maintenance  Performer,  and shall not permit
        any other person  (other than a person  entitled to have  possession  or
        control  of the  Aircraft  under  the terms of this  Agreement)  to have
        possession of or control over the Manuals and  Technical  Records or any
        of them, except with the prior written consent of the Lessor.
<PAGE>

14.5    The Lessee will  compensate the Lessor (a) for overhaul cost and/or life
        limited part replacement cost, if any, reasonably incurred in respect of
        the Aircraft resultant upon the failure to maintain adequate  historical
        records by the Lessee  during the Lease Term as required by the Aviation
        Authority;  and (b) for all recertification costs incurred in respect of
        any Parts resultant upon the failure by the Lessee to maintain JAA Forms
        1 and/or FAA 8130 Tags in respect of each Part.

15.     TITLE AND REGISTRATION

15.1    Title to the Aircraft shall remain vested in the Head Lessor, subject to
        this  Agreement,  the Head  Lease,  the Trust  Agreement,  the  Security
        Documents  and any  assignments,  charges  or other  disposals  the Head
        Lessor or the Beneficiary  and/or the Lessor may make in accordance with
        Clause 23 (Assignment).

        15.2 (a) Subject to Clause 13.3,  the Lessee agrees that all Engines and
Parts  installed on the Airframe or any Engine at Delivery shall be the property
of the Head  Lessor,  subject to the Head Lease,  the Trust  Agreement  and this
Agreement  and that,  subject  to Clause  13.1(f),  13.2 and  Clause  13.3,  all
replacements,  renewals or substitutions  thereof shall be made with engines or,
as the case may be, parts which comply with the  requirements  of Clause 13.1(e)
and Clause 13.1(g).

               (b) Any Engine or Part at any time  removed  from the Airframe or
any Engine  shall remain the property of the Head Lessor and subject to the Head
Lease, the Trust Agreement, this Agreement and the Mortgage until such time as a
replacement  or  substitute  shall have been  installed  (other than pursuant to
Clause  13.1(f),  Clause 13.2 or Clause  13.3) on the  Airframe or the  relevant
Engine in accordance with this Agreement and, in particular,  complying with the
requirements of Clause 13.1(e) and Clause 13.1(g).

               (c) Upon  installation  in  accordance  with  Clause 13.1 (e) and
Clause 13.1(g) but subject to Clauses 13.2 and 13.3, title to any replacement or
substitute  engine or part shall thereupon  without further act vest in the Head
Lessor subject to the Head Lease, the Trust Agreement and this Agreement and the
same shall become subject to the Mortgage for all purposes as though it had been
installed  in or  attached to the  Airframe or an Engine at Delivery  and become
subject to the Head Lease, the Trust Agreement, this Agreement and the Mortgage,
and subject thereto, title to the Engine or Part replaced or substituted (if not
replaced or substituted by an engine or part which at the time of replacement or
substitution  belonged to the Head Lessor or the Beneficiary)  shall vest in the
Lessee free of the  Mortgage  and such  replaced or  substituted  Engine or Part
shall no longer form part of the Aircraft, Airframe or any Engine and references
herein to the Aircraft, Airframe or Engine shall be construed accordingly.
<PAGE>

               (d) The Lessee shall,  without prejudice to the Head Lessor,  the
Beneficiary  or the Lessor,  promptly and duly execute and do and deliver to the
Lessor all such acts, deeds, assurances or things as may be reasonably requested
in writing by the Head Lessor and/or the Lessor and/or the Beneficiary to ensure
that all replacement or substitute  engines or parts installed in or attached to
the  Airframe or any Engine  (other than  pursuant to Clauses  13.1(f),  13.2 or
13.3) shall  satisfy the  requirements  of Clause  13.1(e) and become and remain
part of the Airframe or the relevant  Engine and the property of the Head Lessor
subject to the Head Lease, the Trust Agreement,  this Agreement and the Security
Documents and, without limiting the foregoing, the Lessee shall, if requested by
and without cost to the Lessor, (i) produce evidence reasonably  satisfactory to
the Lessor that all such replacement or substitute engines meet the requirements
of Clause 13.1(e),  (ii) produce evidence satisfactory to the Lessor (including,
but not limited to, legal opinions and bills of sale) that all such  replacement
or  substitute  engines or parts have  become the  property  of the Head  Lessor
subject to the Head Lease, the Trust Agreement,  this Agreement and the Security
Documents and (iii) in the case of replacement or substitute engines,  make such
filings as reasonably requested by Lessor (including, but not limited to filings
at the FAA and filings of Financing  Statements) to perfect any of the interests
referred to in clause (ii).

15.3    Throughout the Lease Period the Lessee shall (a) at its own cost, ensure
        that the Aircraft is registered in the name of the Lessor subject to the
        Head Lease,  the Trust  Agreement and this Agreement or, if not possible
        or  required  by  applicable  law,  in the  name  of the  Lessee  (or if
        applicable  any  permitted  sublessee)  under  the laws of the  State of
        Registration,  such  registration  to reflect (so far as is permitted by
        applicable  law)  the  respective  interests  of the  Head  Lessor,  the
        Beneficiary,  the Lessor,  the Lessee, any Sublessee (if applicable) and
        the Lenders under the Security  Documents;  and (b) ensure that the Head
        Lease (if requested by the Lessor and a copy is provided to the Lessee),
        this Agreement and the Mortgage (so far as permitted by applicable  law)
        are kept,  filed,  registered and recorded in such office or offices and
        on such  registers  in the State of  Registration  (and,  to the  extent
        applicable,  any other state where the Aircraft is based or operated) as
        may be necessary  to ensure the full  legality,  validity,  priority and
        enforceability  thereof  and the  Lessee  shall  not do any act or thing
        which  may   reasonably   be  expected  to   prejudice  or  cancel  such
        registration  PROVIDED  THAT (i) any filing or other  action  undertaken
        with  respect to the  Agreement by Lessee under this clause (b) shall be
        at Lessee's own cost and (ii) the Lessor shall pay the reasonable out-of
        pocket  costs  incurred  by  Lessee  (unless  such  filing  or action is
        undertaken in  connection  with the  occurrence of a Termination  Event)
        with respect to any filing or other action  undertaken  by the Lessee at
        Lessor's  request with respect to the Head Lease or Mortgage  under this
        clause (b).

16.     INSURANCE


16.1    On or before  Delivery and  throughout  the Lease Period and  thereafter
        until the Aircraft is redelivered to the Lessor the Lessee shall obtain,
        maintain and keep in full force and effect insurance with respect to the
        Aircraft and liability insurance with respect to the Aircraft reasonably
        satisfactory  to the  Lessor.  Such  insurances  shall  comply  with the
        provisions  of this Clause 16 and  Schedule 3, and shall be in such form
        and  carried  with such  insurers  and where  appropriate  through  such
        brokers,  and subject to such  exclusions  and  deductibles in each case
        carried with insurers of internationally  recognised  responsibility and
        financial  standing who normally  participate in  international  airline
        insurance  programmes  with respect to aircraft  and through  brokers of
        international  repute,  recognised  in the  aviation  market and of good
        standing.   The  Lessee  shall  provide  to  the  Lessor  a  listing  of
        participating insurers showing the relevant percentage underwritten with
        each  certificate  of insurance  provided to the Lessor.  Subject to the
        satisfaction  of the above criteria,  the insurances  shall be deemed by
        the Lessor to have  satisfied the  requirement of the Lessor with regard
        to the standing of any broker or insurer.

16.2    Throughout  the  Lease  Period  and  thereafter  until the  Aircraft  is
        redelivered  to the  Lessor  the  Lessee  shall  ensure  that all  legal
        requirements  as to the insurance of the Aircraft which may from time to
        time be  imposed by the laws of the State of  Registration  or any state
        to,  from or over which the  Aircraft  shall be flown are duly  complied
        with.

16.3    On or before  Delivery,  the Lessee  shall  provide  the  Lessor  with a
        certificate  of  insurance  prepared in  accordance  with normal  market
        practice and complying  with the  provisions of this Agreement and shall
        procure  that  brokers  issue a letter of  undertaking  addressed by the
        Lessee's  insurance  brokers to the Lessor either in the form set out in
        Schedule 6 or otherwise in form and substance reasonably satisfactory to
        the  Lessor)  that the  Insurances  are and will  continue in full force
        after  Delivery for the balance of the policy year  (subject in the case
        of War Risks policies to usual termination or cancellation  rights). Not
        less than five (5) (or such  later  period  prior to  renewal  as may be
        practicable having regard to the circumstances)  Banking Days before the
        date of  expiration of any of the  Insurances,  the Lessee shall procure
        that its  brokers  shall  give a report  to the  Lessor  specifying  the
        current status of renewal negotiations.  Not less than five (5) (or such
        later period prior to renewal as may be practicable having regard to the
        circumstances)  Banking Days prior to date of such expiration the Lessee
        shall  procure that its brokers  shall  confirm in writing to the Lessor
        that the  Insurances  have been renewed and that all premiums in respect
        thereof as are due upon  renewal  have been paid.  At least two (2) days
        (or such  later  period,  but prior to  renewal,  as may be  practicable
        having  regard  to the  circumstances)  prior  to the  renewal  date the
        renewal  certificates  and letters of  undertaking  with  respect to the
        Insurances  shall be  furnished  to the Lessor.  In addition  the Lessee
        shall upon request  furnish to the Lessor,  as and when  required by the
        Lessor,  relevant  appropriate  extracts of policies  (where there is an
        insurance  issue in  dispute,  coverage  or a claim is  denied) or other
        evidence satisfactory to the Lessor that the requirements of this Clause
        16 and  Schedule 3 are being  complied  with and letters of  undertaking
        from the Lessee's insurance brokers in the form set out in Schedule 6 or
        in such other form as the Lessor may from time to time require.
<PAGE>

16.4    The Lessee shall not,  without the prior written  consent of the Lessor,
        take out insurances,  or permit the Lessee or any Indemnitee to be named
        assured in  insurances  with respect to the Aircraft or any Engine other
        than as required under this Agreement  where such insurances will or may
        prejudice the Insurances or recovery  thereunder  (excluding  insurances
        carried by the  Indemnitees).  The Lessee  shall not create or permit to
        exist  any  Encumbrance  (other  than  any  Encumbrance  created  by the
        Indemnitees)  over the  Insurances,  or its  interest  therein,  save as
        constituted by this Agreement and the other Lessee Documents.

16.5    If the  Insurances  are  not  kept  in  full  force  and  effect  and in
        accordance  with the  provisions of this  Agreement the Lessor,  without
        prejudice  to any  other  rights  it may  have  on the  occurrence  of a
        Termination Event, shall be entitled (but not bound):

        (a)    at any time  while  such  failure is  continuing  to require  the
               Aircraft to remain at an airport  or, as the case may be,  (after
               taking out new  insurances  pursuant to  paragraph  (b) below) to
               proceed  to and  remain at an  airport  designated  by the Lessor
               until the Insurances are in full force and effect; and/or

        (b)    to  pay  the  premiums  due  or to  take  out  and  maintain  new
               insurances  complying  with the  requirements  of this Clause 16,
               including an owner's  interest  policy in such form as the Lessor
               may  reasonably  require,  and any sums so expended by the Lessor
               shall  become  immediately  due and  payable to the Lessor by the
               Lessee  together  with  interest  thereon at the Relevant Rate of
               Interest  from the date of  expenditure  by the Lessor  until the
               date of  reimbursement  thereof  by the Lessee  (both  before and
               after any relevant judgment).

16.6    The Lessor shall be  entitled,  after the expiry or  termination  of the
        Lease  Period,  to require the Lessee at the Lessee's  expense to effect
        and to maintain insurance,  if available,  with respect to its liability
        under the  indemnities set forth in Clause 9.5(a) for such period (which
        shall  not  exceed  two (2)  years  from  the  date of  such  expiry  or
        termination) as the Lessor may reasonably  require (having regard to the
        potential  exposure of the Lessor  and/or the other  Indemnitees  to the
        liabilities   indemnified   against  pursuant  to  Clause  9.5(a))  such
        insurance  to provide  for the Lessor  and the other  Indemnitees  to be
        named as additional insured thereunder to the extent of their respective

<PAGE>

        interests under the said  indemnities,  and the obligation of the Lessee
        to effect the same to continue  notwithstanding the Lessee ceasing to be
        the user or operator of the  Aircraft  and/or any of the Engines  and/or
        the Lessor ceasing to be the owner of the Aircraft.

16.7    If at any time the  Lessor  (acting  reasonably  and  having  regard  to
        internationally  recognised insurance principles and practices generally
        accepted)  considers that either (a) the Insurances effected or procured
        by the Lessee  hereunder do not adequately  protect the interests of the
        Lessor and/or the other Indemnitees, or (b) there has otherwise been any
        significant and material  change in  circumstances  (including,  without
        limitation,  any  change  in the  terms  and  conditions  available  for
        insurances  of the type of the  Insurances  in  relevant  markets  or in
        generally accepted market practice), the Lessor shall be entitled acting
        reasonably  and only where same could have a material  adverse effect on
        the Indemnitees  interests in the Insurances  (without  prejudice to any
        other rights which it may have or acquire under any Lessee  Document) to
        require  the  Lessee to  procure  that the terms and  conditions  of the
        Insurances be changed as soon as is reasonably practicable having regard
        to the  circumstances  and in such a way as the  Lessor  may  reasonably
        require, again having regard to the criteria set out above.

16.8    If the  Insurances  required  by this  Clause 16 and  Schedule 3 are not
        effected and  maintained  through  internationally  recognised  aviation
        markets or in any other  insurance  markets  as the  Lessor may  approve
        (such approval not to be unreasonably withheld) the Lessee shall procure
        that  the   relevant   insurers   maintain  in  full  force  and  effect
        reinsurances with reinsurers of recognised standing in the international
        aviation insurance market.  Such reinsurances shall be on the same terms
        as the original  insurances and shall include,  where  appropriate,  the
        provisions set out in Schedule 3.

        The Lessee  shall use  reasonable  business  efforts as evidenced to the
        reasonable  satisfaction  of the Lessor to have included a "cut through"
        clause in the following  terms or otherwise  reasonably  satisfactory to
        the Lessor in respect of reinsurances noted above:-

        (a)    "The  reinsurers  hereby  agree  that in the  event of any  claim
               arising  under the  reinsurances  in  respect  of a Total Loss or
               other claim where, as provided by the Lease,  such claim is to be
               paid to the  person  named as sole loss payee  under the  primary
               insurances,  the  reinsurers  shall  in  lieu of  payment  to the
               reassured,  its  successors  in interest and assigns,  pay to the
               person  named as sole loss  payee  under the  primary  insurances
               effected  by the Assured  that  portion of any loss due for which
               the  reinsurers  would  otherwise be liable to pay the  reassured
               (subject to proof of loss),  it being  understood and agreed that
               any such payment by the  reinsurers  shall (to the extent of such
               payment) fully  discharge and release the reinsurers from any and
               all further liability in connection therewith"; and
<PAGE>

        (b)    provide in case of any  bankruptcy,  liquidation,  dissolution or
               similar  proceedings  of or  affecting  the  reassured  that  the
               reinsurers'  liability  shall be to make such  payments  as would
               have  fallen  due under the  relevant  policy of  reinsurance  in
               accordance with the  cut-through  Clause referred to above if the
               reassured had (immediately  before such bankruptcy,  liquidation,
               dissolution or similar proceedings) discharged its obligations in
               full under the  original  insurance  policies in respect of which
               the then relevant policy of reinsurance has been effected.

16.9    Unless and until a Relevant Event shall occur,  the Lessor will not give
        any direction to the insurers as contemplated by paragraph  1.2(b)(2) of
        Schedule 3.

16.10   If any of the  Insurances  referred  to in  paragraphs  1.1(a) or (c) of
        Schedule 3 are subject to an annual  aggregate limit and that, by reason
        of any claims  made  thereunder  during the course of any policy year in
        respect of any property subject to such policy,  the aggregate amount of
        coverage  available  thereunder in respect of the balance of such policy
        year shall have been reduced;

        (a)    the Lessee shall forthwith notify the Lessor of the amount of any
               such claim; and

        (b)    the Lessor  shall be  entitled  to require the Lessee to increase
               the aggregate  limit under the relevant  policy to such amount as
               the Lessor may require.

17.     LOSS AND DAMAGE

17.1    Notwithstanding  Clause  6.1  (Lessor's  Warranties  and  Manufacturer's
        Warranties),  throughout the Lease Period the Lessee shall bear the full
        risk  of  any  loss,  destruction,   hijacking,   theft,   condemnation,
        confiscation, seizure or requisition of or damage to the Aircraft and of
        any other  occurrence of whatever kind which shall deprive the Lessee or
        the operator of the  Aircraft for the time being of the use,  possession
        or enjoyment thereof.

17.2    (a)    The Lessee shall give the Lessor  prompt notice in writing of any
               such  occurrence  as is  referred  to in Clause  17.1  other than
               repairable  damage the likely cost of rectification of which will
               not exceed in aggregate $[ ]*, or, in relation to any Engine,  $[
               ]* in aggregate.

        (b)    The Lessee shall supply to the Lessor all necessary  information,
               documentation and assistance which may be reasonably requested by
               the  Lessor  in  connection  with  making  any  claim  under  the
               Insurances.

17.3    (a)    If the  Aircraft  shall  become a Total  Loss  during  the  Lease
               Period,  the Lessee shall pay, or procure that the insurers  pay,
               to either  the Head  Lessor,  the Lessor or the  Lenders  (as the
               Lessor  may  direct  in  writing)  being  loss  payee  under  the
               Insurances  within ninety (90) days (or such longer period as may
               be  agreed)  of the date on which the Total  Loss  occurred,  the
               Agreed  Value  together  with all  amounts  of rent and any other
               amounts then due and payable under this Agreement.
<PAGE>

        (b)    For the  purposes of this  Agreement a Total Loss shall be deemed
               to have occurred:

               (i)  in the case of an actual total loss,  at noon (London  time)
                    on the actual date the Aircraft was lost or, if such date is
                    not  known,  noon  (London  time)  on the day on  which  the
                    Aircraft was last heard of;

              (ii)  in the case of any of the events  described in sub-paragraph
                    (a) of the  definition  of Total Loss  (other than an actual
                    total loss),  upon the date that notice claiming the loss of
                    the Aircraft is given to the relevant  insurers,  unless the
                    insurers do not forthwith admit such claim,  when such Total
                    Loss shall be deemed to have  occurred  at the date and time
                    at which either a total loss is subsequently admitted by the
                    insurers or a competent court or arbitration tribunal issues
                    a judgment to the effect that a total loss has occurred;

              (iii) in the case of any of the events  described in  subparagraph
                    (b) of the  definition  of  Total  Loss,  upon  the  date of
                    occurrence of such destruction, damage or rendering unfit;

              (iv)  in the case of  Compulsory  Acquisition,  upon the date upon
                    which the relevant  requisition of title or other compulsory
                    acquisition,  requisition,   appropriation,   expropriation,
                    deprivation or confiscation occurs; and

              (v)   in the case of any of the events  described in sub-paragraph
                    (d) of the definition of Total Loss,  upon the expiry of the
                    period of ninety (90) days referred to in such  subparagraph
                    (d) after the date upon which the relevant hijacking, theft,
                    condemnation,  confiscation,  capture, detention, seizure or
                    requisition for use or hire occurred.

17.4    The Lessee  shall  continue  to pay rent on the days and in the  amounts
        required under this Agreement  notwithstanding  any Total Loss; provided
        always that no further  installments  of rent shall become due after the
        date on which all sums due under Clause  17.3(a) shall have been paid in
        full, and the Lease Period shall  terminate on the date of such payment.
        Upon such  termination of the Lease Period and following  payment of the
        Agreed  Value,  the  Lessor  shall  make a payment  to the Lessee in the
        amount  described in paragraph 5 of Letter Agreement No.1. to the extent
        that Lessor received insurance proceeds or Requisition Compensation with
        respect to such Total Loss in excess of the amounts  required to be paid
        by Lessee under Clause  17.3(a) and, for the avoidance of doubt,  Lessor
        shall be entitled to apply such excess insurance proceeds or Requisition
        Compensation for the purpose of making such payment.
<PAGE>


17.5    In the event of repairable damage to the Aircraft or any of the Engines,
        or the  loss or  destruction  of any  Engine  (when  no  Total  Loss has
        occurred),  the Lessor or the Lenders as loss payee under the Insurances
        shall  either pay any  insurance  moneys  received  by it or them to the
        Lessee  upon the Lessee  furnishing  evidence  to the  Lessor  that such
        damage has been made good or  repaired  or put in hand for repair or, in
        the case of the loss or destruction of any Engine,  utilize the relevant
        insurance moneys in the purchase of a replacement Engine provided always
        that if a Relevant  Event has  occurred  and is  continuing,  the Lessor
        shall be entitled to require that such insurance moneys be applied in or
        towards  settlement  of any  amounts  owing by the  Lessee to the Lessor
        under this Agreement.

17.6    In the event of repairable damage to the Aircraft or any of the Engines,
        or the  loss or  destruction  of an  Engine  (when  no  Total  Loss  has
        occurred),  and if the  insurance  moneys  paid in respect  thereof  are
        insufficient  to pay  the  cost or  estimated  cost  of  making  good or
        repairing  such damage or the cost of purchasing a  replacement  Engine,
        the Lessee will pay the deficiency.

17.7    Any  Requisition  Compensation  on account of a  Compulsory  Acquisition
        received  at any time by  Lessor  or by  Lessee  from  any  governmental
        authority or any other source will be directed or paid to Lessor (if not
        already  received by Lessor)  and  applied by Lessor as follows:  (a) so
        much of such  payments  as shall not exceed  the Agreed  Value and other
        amounts  payable  by the  Lessee  pursuant  to Clause  17.3(a)  shall be
        applied in reduction of Lessee's obligation to make such payments to the
        extent not already  paid by Lessee and, to the extent such  payments are
        fully  paid by such  application  or have  already  been made in full by
        Lessee,  to reimburse  the Lessee;  (b) the remaining  balance,  if any,
        shall be paid to the Lessee up to an amount  equal to Lessee's  Interest
        (if any) minus any amount  paid by Lessor to Lessee  pursuant  to Clause
        17.4.  and (c) any amount  remaining  thereafter  shall be  retained  by
        Lessor.

18.     REQUISITION OR GROUNDING

18.1    If the Aircraft is  requisitioned  for hire by any governmental or other
        competent  authority during the Lease Period then,  unless and until the
        Aircraft  becomes a Total Loss following such requisition and the Lessee
        shall have made payment of all sums due pursuant to Clause 17.3(a),  the
        lease of the Aircraft to the Lessee under this Agreement  shall continue
        in full force and effect  (subject always to the provisions of Clause 21
        (Lessor's  Rights  Following a Termination  Event)) and the Lessee shall
        remain fully responsible for the due compliance with all its obligations
        under this  Agreement  other than such  obligations  which the Lessee is
        unable to comply with solely by virtue of such requisition.

18.2    If the Lessee  shall duly  comply  with all its  obligations  under this
        Agreement, save as mentioned in Clause 18.1, the Lessee shall during the
        Lease Period,  be entitled to all requisition hire paid to the Lessor or
        to the Lessee on account of such requisition.
<PAGE>

18.3    The Lessee shall as soon as practicable after the end of any requisition
        for hire,  cause the Aircraft to be put into the  condition  required by
        this Agreement,  and where that requisition  shall end after the date on
        which the Lease Period would  otherwise  have expired or terminated  but
        for such  requisition,  the Lessee shall, as soon as practicable,  cause
        the Aircraft to be put into the redelivery  condition required by Clause
        19, allowance being made for fair wear and tear in respect of the period
        from the date on which the Lease Period would  otherwise have expired or
        terminated  but  for  such  requisition   until  the  actual  expiry  or
        termination of the Lease Period.

18.4    The Lessor shall be entitled to all  compensation  payable in respect of
        any change in the structure,  state or condition of the Aircraft arising
        during the period of  requisition  for hire. The Lessor shall apply such
        compensation  in  reimbursing  the Lessee for the cost of complying with
        its obligation under Clause 18.3,  provided always that if a Termination
        Event has  occurred and is  continuing,  the Lessor shall be entitled to
        apply such compensation in or towards settlement of any amounts owing by
        the Lessee under this Agreement.

18.5    If the Aviation  Authority  has grounded the Aircraft and other  similar
        U.S.   registered  Boeing  737  aircraft  for  reasons  related  to  the
        airworthiness  of such  aircraft  and the  Lessee  has  been  diligently
        attempting  since such  grounding to correct the cause of such grounding
        and,  notwithstanding  such  effort,  the  grounding  continues:  (a) no
        Termination  Event  shall  arise  hereunder  solely  as a result  of the
        Aircraft not holding a currently effective  Certificate of Airworthiness
        due to such grounding and (b) if such grounding continues after the date
        on which the Lease Period would otherwise have expired or terminated but
        for such  grounding,  the lease of the Aircraft to the Lessee under this
        Agreement  shall  continue in full force and effect and the Lessee shall
        remain fully responsible for the due compliance with all its obligations
        under this Agreement and the Lessee shall, as soon as practicable  after
        the cause of such  grounding is corrected,  cause the Aircraft to be put
        into the  redelivery  condition  required  by Clause 19 and  Schedule 4,
        allowance  being  made for fair wear and tear in  respect  of the period
        from the date on which the Lease Period would  otherwise have expired or
        terminated  but  for  such  requisition   until  the  actual  expiry  or
        termination of the Lease Period.

19.     RE-DELIVERY

19.1    At the end of the Lease Period  (other than  following a Total Loss) the
        Lessee at its own expense shall  redeliver the Aircraft to the Lessor at
        the Re-delivery  Location,  and the Lessee shall provide such assistance
        as  the  Lessor  may   reasonably   request  in   connection   with  the
        de-registration   and  export  of  the   Aircraft   from  the  State  of
        Registration.
<PAGE>

19.2    On  re-delivery,  the Lessee shall ensure that (i) the Aircraft shall be
        maintained and repaired in compliance  with Clause 13.1(d) and all other
        requirements  of this  Agreement,  (ii)  the  Engines  installed  on the
        Aircraft at Delivery (or,  replacement or substitute Engines pursuant to
        Clause 13.1(e) or Clause  13.3(c)(ii)(dd)  and, in either event, meeting
        the  requirements  of Clause 13.1(e),  Clause  13.1(g),  Clause 15.2 and
        Schedule 4, paragraph 3, shall be installed on the Aircraft; (iii) there
        shall be a current  Certificate of  Airworthiness  (and the Lessee shall
        cooperate,   where  requested  by  the  Lessor,   to  obtain  an  export
        certificate of  airworthiness)  issued in respect of the Aircraft by the
        Aviation Authority in the public transport (passenger) category and such
        current  certificates of maintenance  issued as shall allow the Aircraft
        to be used for the public  transport  of  passengers  or cargo under the
        regulations of the Aviation  Authority;  (iv) the Aircraft shall be in a
        condition qualifying for immediate certification of airworthiness by the
        Aviation  Authority  and the  FAA;  (v) the  Aircraft  shall be clean by
        Airline  Standards  (vi)  all  applicable  vendor's  and  manufacturer's
        service bulletin kits received by the Lessee or any Sub-Lessee  relating
        to the Aircraft  shall be installed on the Aircraft at no cost to Lessor
        or delivered  separately (with reasonable advance notice to Lessor) at a
        charge to the Lessor not to exceed Lessee's direct cost of procuring and
        delivering  such kits to the Lessor in a serviceable  condition with all
        relevant  documentation  attached  thereto  provided that the Lessor may
        decline (with  reasonable  advance  notice to Lessee) to accept any such
        noninstalled kits; (vii) the livery, insignia and markings of the Lessee
        or any  operator  of the  Aircraft  shall  have been  stripped  from the
        Aircraft which shall have been rubbed down and repainted at the Lessee's
        cost in neutral  white or such  other  base  colour as is advised by the
        Lessor prior to redelivery;  (viii) the Aircraft shall be free and clear
        of all Encumbrances other than Lessor's Encumbrances;  (ix) the Aircraft
        shall  have  no  deferred   maintenance,   repair  or  inspection  items
        outstanding;  and (x) all Aircraft  repairs shall be permanent and where
        commercially feasible flush type repairs (provided that the flush repair
        does not require  substantial rework of adjacent airframe structures and
        a nonflush repair achieves  equivalent  technical  standards) and in any
        event be in accordance with the Manufacturer's  structural repair manual
        or as otherwise  approved by the FAA and the Aircraft  shall comply with
        the Return Conditions set out in Schedule 4.

19.3    During  the  period of  thirty  (30) days  prior to  re-delivery  of the
        Aircraft,  the Lessee, at no cost to the Lessor, shall, if the Lessor so
        requests, make the Manuals and Technical Records available to the Lessor
        and during the entire  period of the C check  required  upon  redelivery
        make the Aircraft  available  for such  detailed  inspection in order to
        verify that the condition of the Aircraft  complies with the  provisions
        hereof. During such periods, the Lessor may accomplish the following:

        (a)    inspection of the Manuals and Technical Records;
<PAGE>

        (b)    appropriate  functional  testing  of the  Aircraft,  Engines  and
               Parts,  including without limitation,  a boroscope inspection,  a
               spectrographic   oil  analysis  programme  (SOAP)  sample  and/or
               magnetic chip detection inspection of the Engines;

        (c)    up to a two hour test  flight with the  Lessor's  representatives
               (up to two) as  observers,  including an engine  condition run on
               each Engine; and


        (d)    The  detailed   inspections  and  checks  during  the  redelivery
               procedures   specified  in  this  Clause  shall  be  commercially
               reasonable  in manner and  extent and will be carried  out by the
               Lessor  solely so as to  enable  the  Lessor  to verify  that the
               Aircraft  complies with the provisions of this Agreement and such
               inspections and checks will be appropriate and reasonable  having
               regarded to: (i) the age of the  Aircraft;  (ii) the  maintenance
               history  of the  Aircraft;  and (iii) any then  current  aviation
               industry issues regarding such model of Aircraft. Opening of bays
               and  panels  may  not  be  required   unless  Lessor   reasonably
               demonstrates  a  requirement  therefor and in no event shall such
               panels or bays be opened arbitrarily or unnecessarily.

19.4    (a)    If  on  re-delivery  the  Aircraft  (including  the  Manuals  and
               Technical  Records)  shall not be in the  condition  required  by
               Clause  19.2,  the Lessor shall be entitled to require the Lessee
               at the Lessee's expense to rectify any defects or deficiencies in
               the  Aircraft  when  it is  redelivered,  and  the  Lessee  shall
               promptly  comply  with any such  requirement.  To the extent that
               such rectification  extends beyond the Lease Term, the Lessor may
               at its sole  discretion (i) remedy such defects and  deficiencies
               and  recover on demand  from the  Lessee  the costs so  incurred,
               together  with interest at the Relevant Rate of Interest from the
               date of  expenditure  and demand for payment by the Lessor of the
               relevant  cost  through  the day  prior to the  date of  recovery
               thereof  from the  Lessee  (both  before  and after any  relevant
               judgment),  or (ii)  continue  the  Lease  Period on a day to day
               basis until such  non-compliance  is rectified by the Lessee with
               rent  being  payable  by the Lessee at the rate at which rent was
               payable at the date on which  re-delivery  would  otherwise  have
               occurred,  PROVIDED,  HOWEVER,  that if  (aa)  such  defects  and
               deficiencies  are Minor Defects,  (bb) the Aircraft is capable of
               being placed in immediate  commercial  use  notwithstanding  such
               Minor Defects and (cc) no Relevant Event has then occurred and is
               continuing other than such Minor Defects, the Lessor shall accept
               re-delivery  of the  Aircraft  as  provided in clause (i) of this
               sentence   subject  to  such  Minor  Defects.   The  Lessee  will
               compensate the Lessor for loss of value to the Aircraft where any
               damage  has  resulted  in  permanent  structural  changes  to the
               Aircraft's  type  design  excluding  fair  wear and  tear.  Minor
               Defects means defects or  deficiencies  in the Aircraft which the
               Lessee  was unable to correct by the end of the Lease Term or any
               extension of the Lease Period pursuant to the preceding  sentence
               of this Clause through commercially  reasonable efforts and which

<PAGE>

               (1) in no single  case or in the  aggregate  will cost the Lessor
               more than $[ ]*, as reasonably estimated by the Lessor, to remedy
               (2) can be  remedied  by the Lessor or the next  operator  of the
               Aircraft within thirty (30) days of re-delivery to Lessor, (3) do
               not  prevent  the  Aircraft   from  holding  a  fully  valid  and
               unconditional standard Certificate of Airworthiness issued by the
               FAA,  (4) will not  prevent  the  Aircraft  from being  granted a
               standard   Certificate   of   Airworthiness   in  the   State  of
               Registration  to which it is being exported (if any) and (5) does
               not  constitute  a  commercially  reasonable  basis  for the next
               operator of the Aircraft to refuse to accept delivery thereof.

        (b)    Prior to the  re-delivery  of the  Aircraft and upon the Lessor's
               request,  the Lessee  will  ensure  that there is provided to the
               Lessor or its agent reasonable access to the Approved Maintenance
               Programme  and the  Manuals  and  Technical  Records  in order to
               facilitate  the  Aircraft's   integration   into  any  subsequent
               operator's  fleet.  The Lessee will upon  return of the  Aircraft
               deliver to the Lessor a certified  true current and complete copy
               of  the  Approved  Maintenance  Programme  which  shall  be  kept
               confidential  and promptly  returned to Lessee  together with all
               copies  thereof  after any use of such  Maintenance  Programme by
               Lessor  which  shall  be  solely  for  bridging  to a  subsequent
               operator's maintenance programme.

19.5    Upon  re-delivery of the Aircraft to the Lessor,  an adjustment shall be
        made in respect of fuel on board the  Aircraft  at the time of  Delivery
        and at the time of  re-delivery  at the price  prevailing at the time of
        re-delivery at the Re-delivery Location.

19.6    Upon  re-delivery  of the Aircraft  provided that (i) no Relevant  Event
        shall have occurred or be continuing;  and (ii) the Lessee has satisfied
        all of its obligations then due under this Agreement (including, without
        limitation,  its obligation to redeliver the Aircraft in accordance with
        this Clause 19 and  Schedule  4), the Lessor shall make a payment to the
        Lessee in the amount described in paragraph 5 of Letter Agreement No. 1.
        Notwithstanding the foregoing,  if the Aircraft is re-delivered  subject
        to Minor Defects as provided in Clause 19.4(a) and no Relevant Event has
        then occurred and is continuing other than such Minor Defects, upon such
        re-delivery,  the Lessor shall make a payment to the Lessee in an amount
        equal to the amount  described in paragraph 5 of Letter  Agreement No. 1
        less an amount (the "Remedy Amount")  reasonably  estimated by Lessor to
        be sufficient to pay for its costs to remedy such Minor  Defects.  If in
        fact it costs  Lessor  less than the Remedy  Amount to remedy such Minor
        Defects,  the  Lessor  shall  make a payment  to the Lessee in an amount
        equal to the difference between the Remedy Amount and such actual costs.
        If such actual costs exceed the Remedy Amount,  the Lessee shall pay the
        Lessor such deficiency as provided in Clause 19.4(a).

19.7    Notwithstanding  anything  to the  contrary  in Clause 19 or Schedule 4,
        unless a Termination Event has occurred and is continuing (in which case
        this Clause 19.7 shall not apply),  the C Check and all other procedures
        and inspections required by Schedule 4 will be performed at the Lessee's
        principal  maintenance facility in the United States and the inspections
        and test  flight  set  forth in Clause  19.3  shall  take  place at such
        location. Following such procedures, inspections and test flight, either
        the  Aircraft  will be in the  condition  required by Clause 19.2 or the
        provisions of Clause 19.4 (a) will apply  (collectively the "Predelivery
        Requirements").  After the Predelivery Requirements have been satisfied,
        the Lessee shall ferry the Aircraft to the Redelivery  Location with the
        Lessor's  representatives  (up to two) as observers.  At the  Redelivery
        Location, the Aircraft shall be re-delivered by the Lessee in compliance
        with all terms of Clause 19 and Schedule 4.  Following  the ferry flight
        to the Redelivery  Location,  the Lessor shall conduct engine  boroscope
        inspections  and an  external  walkaround  inspection  and Lessee  shall
        correct any deficiencies and defects discovered.  If the Aircraft is not
        in the  condition  required by Clause  19.2,  the  provisions  of Clause
        19.4(a) will apply.

19.8    The Lessee shall  indemnify and hold harmless the  Indemnitees  from and
        against any and all liabilities, damages and losses (including costs and
        expenses incidental thereto) arising by reason of death or injury to any
        observer  or  employee  of the  Lessee,  arising  out of,  or in any way
        connected with the ferry flight set forth in Clause 19.7.

19.9    The Lessor shall indemnify and hold harmless the Lessee from and against
        any and  all  liabilities,  damages  and  losses  (including  costs  and
        expenses incidental thereto) arising by reason of death or injury to any
        observer or employee of the Lessor,  arising out of, or in any connected
        with the ferry flight set forth in Clause 19.7.

20.     TERMINATION EVENTS

               (ii) any  insurer  or  reinsurer  in  respect  of any part of the
               Insurances  cancels any part of the  Insurances  or  disclaims or
               repudiates   liability  by  reason,   in  either  case,   of  any
               mis-statement in any proposal for the Insurances or for any other
               failure or default on the part of the Lessee  and, in the case of
               this clause (ii),  if the  Insurances  continue in full force and
               effect as to Lessor,  Beneficiary,  Head Lessor and Lenders, (aa)
               such cancellation, disclaimer or repudiation is not withdrawn and
               (bb) the Insurances  which are the subject of such  cancellation,
               disclaimer or  repudiation  are not replaced  with  Insurances in

               within  ten (10)  days of the  occurrence  of such  cancellation,
               disclaimer or repudiation; or

        (c)    the Lessee  commits  any breach of or omits to observe any of the
               obligations or  undertakings  expressed to be assumed by it under
               this Agreement  (other than those referred to in sub-clauses  (a)
               and (b)  above)  or any of the other  Lessee  Documents  and,  in
               respect of any such  breach or  omission  which in the opinion of
               the Lessor is capable  of remedy,  such  action as the Lessor may
               require  shall not have been taken within thirty (30) days of the
               Lessor  notifying the Lessee of such default and of such required
               action  or,  if any  such  breach  or  omission  is not  cured or
               remedied  within said thirty (30) days  notwithstanding  diligent
               efforts by Lessee to effect such cure or remedy, Lessee continues
               such diligent efforts and such breach or omission is not cured or

               Documents  is or  proves  to have  been  untrue  in any  material
               respect when made or deemed repeated and continues to be material
               at the time relied upon by Lessor for purposes of  establishing a
               Termination Event; or

        (e)    Lessee  shall  default in the payment of any  obligation  for the
               payment of borrowed  money,  for the deferred  purchase  price of
               property  or for the  payment of rent under any lease which has a
               principal  amount of [ ]* Dollars ($[ ]*) or more  determined  in
               the case of borrowed  money by the amount  outstanding  under the
               agreement pursuant to which such borrowed money was borrowed,  in
               the case of a deferred  purchase  price by the remaining  balance
               and in the case of a lease by the present discounted value of the
               remaining  rent or hire  payable  thereunder  (ignoring  any fair
               market  renewal)  when the same  becomes  due if such  nonpayment

               termination or declaration of default under such lease, or Lessee
               shall default in the performance of any other term, agreement, or

               that if, in any such case,  such  consent  has been  unreasonably
               withheld or delayed, such case shall not constitute a Termination
               Event under this Clause 20.1(r).

<PAGE>

        Clauses  20.1(i),  (j), (k), (l) and (m) the Lessor need not declare the
        Agreement to be in default); and at any time thereafter,  the Lessor may
        do, and the Lessee shall comply with,  one or more of the following with
        respect  to all or any  part of the  Airframe  and 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:

               immediate  possession  of and  remove  such  Airframe  or Engines
               without the necessity for first  instituting  proceedings,  or by

               the same at the  Lessee's  premises  until  disposal  thereof  by
               Lessor),  and the Lessee  shall  comply  therewith,  all  without
               liability  to Lessor  for or by  reason  of such  entry or taking
               possession or storage,  whether for the  restoration or damage to

               at any time exercise, any of its rights under paragraph (a) above
               with  respect  to all or any  part of the  Aircraft,  Lessor,  by
               written  notice  to the  Lessee  specifying  a  payment  date not
               earlier  than ten (10)  days  from the date of such  notice,  may
               demand  that the  Lessee  pay to  Lessor,  and  Lessee  shall pay
               Lessor,  on  the  payment  date  specified  in  such  notice,  as
               liquidated damages for loss of a bargain and not as a penalty (in
               lieu of the  installments of rent due on the Aircraft,  Airframe,
               Engine or Part  thereof  for periods  commencing  on or after the
               payment date in such notice), any unpaid installments of rent due
               for periods prior to the period  commencing with the payment date
               specified in such notice plus an amount  equal to the excess,  if

               Treasury Bills of similar maturity;

        (c)    Terminate  the Lease Term and/or the  leasing of the  Airframe or
               any or all of the Engines,  or 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 for the breach hereof.

21.2    In addition to the amounts  set forth in Clause  21.1,  Lessee  shall be
        liable for any and all unpaid amounts due hereunder  before or after any
        termination hereof and for all costs and expenses (including  reasonable
        attorneys' fees and disbursements) incurred by Lessor and Beneficiary in
        connection with or as a result of any  Termination  Event or exercise of
        remedies  hereunder,  including,  but not  limited to, (i) all costs and
        expenses  incurred in connection  with the return of the Airframe or any
        Engine in accordance  with the terms of Section 19 and Schedule 4 hereof
        and/ or in connection with restoring the Aircraft or any portion thereof
        to the  condition  required  by  Section  19 and  Schedule  4 hereof and
        remarketing  the Aircraft,  (ii) any loss,  premium,  penalty or expense
        which may be incurred in repaying  funds  raised to finance the Aircraft
        or in  unwinding  any swap,  forward  interest  rate  agreement or other
        financial  instrument  relating in whole or in part to the Head Lessor's
        or the Beneficiary's financing of the Aircraft and (iii) interest at the
        Relevant Rate on any amount not paid when due under this Agreement,  and
        all such obligations  shall survive any termination of this Agreement or
        the leasing of the Aircraft or any portion thereof hereunder.  All costs
        and expenses  referred to in the preceding  sentence shall be payable by
        Lessee  upon  demand  by the  Lessor  or  Beneficiary  unless  otherwise
        specified  in this  Agreement.  Except as otherwise  expressly  provided
        above,  no  remedy  referred  to in this  Clause  21 is  intended  to be
        exclusive,  but each shall be  cumulative  and in  addition to any other
        remedy  referred to above or otherwise  available to Lessor at law or in
        equity.  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 such  other  remedies.  No  express or
        implied waiver by Lessor of any Termination Event hereunder shall in any
        way be,  or be  construed  to be, a waiver of any  future or  subsequent
        Termination Event.

21.3    For the purposes of Subclause  21.1 (b) above,  the "fair market  rental
        value" of the  Aircraft,  Airframe,  any Engine or Part thereof shall be
        the  rental  value,  net of all costs and  expenses  of  recovering  the
        Aircraft,  Airframe  or any Engine or Part  thereof  and  restoring  its
        condition to the condition required  hereunder,  which would be obtained
        in an arm's-length  transaction  between an informed and willing lessee,
        under no compulsion to lease, and an informed and willing lessor,  based
        upon the actual condition and location of the Aircraft,  Airframe or any
        Engine of Part  thereof,  which value shall be determined by a reputable
        firm of aircraft appraisers selected by Lessor or Beneficiary.  The cost
        of such appraisal shall be borne by Lessee.

21.4    If the Lessee  fails to comply  with any of its  obligations  under this
        Agreement the Lessor may, without being in any way obliged so to do, and
        without being  responsible  for so doing,  and without  prejudice to the
        ability  of the  Lessor to treat that  non-compliance  as a  Termination
        Event,  effect  compliance  on the  Lessee's  behalf,  and if the Lessor
        incurs any  expenditure in effecting such compliance the Lessor shall be

<PAGE>

        entitled  (without  prejudice  to Clause 21.1 or Clause 21.2) to recover
        such  expenditure  from the Lessee together with interest thereon at the
        Relevant  Rate of Interest  from the date on which such  expenditure  is
        incurred by the Lessor  until the date of  reimbursement  thereof by the
        Lessee (both before and after any relevant judgment).

21.5    The Lessee's obligations under this Clause 21 shall survive  the end of
        the Lease Period.

23.     ASSIGNMENT

23.1    (a)   The  Lessee may not assign  or,  except as herein  provided  with
               respect to  subleases,  otherwise  transfer  any of its rights or
               obligations  under  this  Agreement  without  the  prior  written
               consent of the Lessor.

        (b)    The  Lessor may assign or  otherwise  transfer  any or all of its
               rights  under,  and the benefit of,  this  Agreement  at any time
               during the Lease  Period  with the  consent of the  Lessee,  such
               consent not to be unreasonably denied,  provided,  however,  that
               the consent of the Lessee  shall not be required  with respect to

<PAGE>

               any  assignment  (i) to the Head  Lessor or Lenders as  otherwise
               contemplated  herein, (ii) to any affiliate of the Lessor that is
               a  Citizen  of  the  United  States,  (iii)  to  any  financially
               responsible  company  or  person  (as  reasonably  determined  by
               Lessor)  that is a Citizen  of the  United  States  and is not an
               airline that competes  directly with Lessee on specific routes or
               (iv) to any assignment that occurs after a Termination  Event has
               occurred and is continuing  which is made in  consequence of such
               Termination  Event.  Except  in  the  case  of an  assignment  or
               transfer that occurs after a  Termination  Event has occurred and
               is  continuing  (including  at the  time  of such  assignment  or
               transfer),  each assignee or transferee under this Clause 23.1 or
               under  Clause  23.2  shall  deliver,   as  a  condition  to  such
               assignment or transfer, a Letter of Quiet Enjoyment to the Lessee
               at or before such assignment or transfer.  Under no circumstances
               shall Lessee be obligated to pay any assignee or  transferee  any
               greater amount or incur any greater obligation than that which it
               would have been obligated to pay or incur under this Agreement if
               no  assignment  or  transfer  had taken  place nor shall any such
               assignment impair any right of the Lessee under this Agreement or
               impose any additional obligation on Lessee.

23.2    It is  understood  that the Head  Lessor,  the  Beneficiary,  the Lessor
        and/or  the  Lenders  may from  time to time  effect,  amend,  modify or
        replace the security  arrangements  in respect of the  financing  of, or
        refinance the Aircraft;  the Lessee agrees to cooperate  with the Lessor
        in connection  therewith and in connection with the Security  Documents,
        any mortgage and any  assignment  or transfer by the Lessor  pursuant to
        Clause 23.1 and to execute and deliver to the Lessor such  documents  as
        are reasonably requested by the Head Lessor, the Beneficiary, the Lessor
        or the Lenders  relating  thereto  provided no such documents impair any
        right granted to Lessee hereunder or impose any additional obligation on
        Lessee not otherwise  required by this  Agreement.  The Lessee agrees to
        change  the  nameplates  referred  to in  Clause  13.1  and to give  all
        reasonable  assistance  as may be  reasonably  requested  in  writing by
        Lessor for the perfection and  acknowledgement of the rights of the Head
        Lessor,  the  Beneficiary,  the  Lessor  and/or the  Lenders  and/or any
        mortgagee  hereunder or thereunder.  The Lessor shall pay the reasonable
        out-of-pocket   expenses   incurred  by  the  Lessee  in  executing  and
        delivering  documents  or  otherwise  cooperating  at the request of the
        Lessor  in   connection   with  any   assignment  or  transfer  made  as
        contemplated  by Clause 23.1 and Clause 23.2.  Nothing in Clause 23.1 or
        23.2 shall restrict the right of the  Beneficiary to assign the Aircraft
        and  Lease to a  successor  trustee  pursuant  to the terms of the Trust
        Agreement  provided  that such  successor  trustee  is capable of making
        substantially  the same  representations  of the Lessor as in clause 2.5
        hereof.

23.3    The agreements, covenants, obligations and liabilities contained in this
        Agreement, including, but not limited to all obligations to pay rent and
        indemnify  the  Lessor,  are made for the  benefit  of the  Lessor,  any
        assignee or transferee of the Lessor and their respective successors and
        assigns.

24.     MISCELLANEOUS

24.1    This  Agreement  (together  with  Letter  Agreement  No. 1 and any other
        related side letters)  contains the entire agreement  between the Lessor
        and the Lessee  relating to the leasing of the  Aircraft,  and the terms
        and conditions of this Agreement  shall not be varied  otherwise than by
        an  instrument  in writing of even date  herewith or  subsequent  hereto
        executed by or on behalf of the Lessor and the Lessee.

24.2    No failure  or delay on the part of the  Lessor or Lessee in  exercising
        any right,  power or remedy  under  this  Agreement  shall  operate as a
        waiver thereof nor shall any single or partial exercise by the Lessor or
        Lessee of any such right,  power or remedy preclude any other or further
        exercise  thereof or the exercise of any other  right,  power or remedy.
        The rights and remedies  provided in this  Agreement are  cumulative and
        are not exclusive of any rights and remedies provided by law.

24.3    Subject to the periods of grace  referred to in Clause 20, time shall be
        of the  essence as regards the  performance  by the Lessee and Lessor of
        their respective obligations under this Agreement.

24.4    The Lessee and Lessor  shall from time to time do and perform such other
        and  further  acts and  execute  and  deliver  any and all such  further
        instruments  as may be required by law or  reasonably  requested  by the
        other to establish,  maintain and protect the rights and remedies of the
        Head Lessor, the Beneficiary,  the Lessor, the Lenders or the Lessee and
        to carry out and  effect  the  intent  and  purposes  of this  Agreement
        provided  that no party shall be required  under this Clause to take any
        action or  execute  and  deliver  any  document  that  would  materially
        increase the  obligations  or impair the rights of such party under this
        Agreement.

24.5    This  Agreement  may be  executed  by the  parties  hereto  in  separate
        counter-parts,  each of which, when so executed and delivered,  shall be
        an original,  and both  counter-parts  shall constitute one and the same
        instrument.

24.6    If any  provision of this  Agreement  shall become  invalid,  illegal or
        unenforceable  in any respect under any law, the validity,  legality and
        enforceability  of the remaining  provisions of this Agreement shall not
        in any way be affected or impaired.

24.7    The Lessor is  entering  into this  Agreement  in its  capacity as Owner
        Trustee and not in its  individual  capacity as such.  The Lessor in its
        individual  capacity shall not be liable to the Lessee for or on account
        of any statements, representations, warranties, covenants or obligations
        stated to be those of the Lessor hereunder.  The Lessor may exercise its
        rights  and  remedies  hereunder  and under the other  Lessee  Documents
        through agents and representatives,  including,  but not limited to, the
        Beneficiary and its agents and representatives.
<PAGE>

24.8    Any amount  which the terms of this  Agreement  provide  that the Lessor
        shall pay to the Lessee but for the occurrence of a Termination Event or
        Relevant Event shall,  unless application of such amount is provided for
        elsewhere in this Agreement and such amount has been so applied, be paid
        by Lessor to Lessee  at such time as no  Termination  Event or  Relevant
        Event (as the case may be) has occurred and is continuing.

24.9    All  obligations   under  this  Agreement  are  continuing   obligations
        throughout  the  Lease  Period.  The end of the Lease  Period  shall not
        prejudice  or  otherwise  limit the  accrued  or  surviving  rights  and
        obligations  of the  parties  hereunder  of  under  any  of  the  Lessee
        Document.

25.     LAW AND JURISDICTION

25.1    This Agreement is governed by and shall be construed in accordance  with
        the Governing Law.

25.2    For the benefit of the Lessor and Lessee, the parties  irrevocably agree
        that any legal action or proceedings  in connection  with this Agreement
        may be brought in the Courts,  which shall have  jurisdiction  to settle
        any disputes  arising out of or in connection with this  Agreement.  The
        parties  hereto hereby  irrevocably  and  unconditionally  submit to the
        jurisdiction of the Courts.  The submissions to such jurisdiction  shall
        not (and shall not be construed so as to) limit the rights of the Lessor
        and Lessee to take  proceedings  against the other in any other court of
        competent  jurisdiction,  nor shall the  taking  of  proceedings  by the
        Lessor or Lessee in any one or more jurisdictions preclude the taking of
        proceedings by the Lessor or Lessee in any other  jurisdiction,  whether
        concurrently  or not.  The  Lessee  and  Lessor  irrevocably  waives any
        objection  it may now or  hereafter  have to the  laying of venue of any
        action or  proceeding in any court and any claim it may now or hereafter
        have that any action or proceeding  has been brought in an  inconvenient
        forum. The Lessee hereby irrevocably  designates,  appoints and empowers
        CT Corporation System at present of 1633 Broadway,  New York, N.Y. 10019
        to receive for it and on its behalf service of process issued out of the
        Courts in any legal action or proceeding arising out of or in connection
        with this Agreement and/or any other Lessee Document.  The Lessor hereby
        irrevocably  designates,  appoints and empowers ORIX USA  Corporation at
        present of 780 Third Avenue, 48th Floor, New York, N.Y. 10017 to receive
        for it and on its behalf  service of process issued out of the Courts in
        any legal action or proceeding arising out of or in connection with this
        Agreement and/or any other lessor document.

25.3    The Lessee and Lessor  agrees  that in any legal  action or  proceedings
        against it or its assets in connection with this Agreement,  no immunity
        from  legal  action  or  proceedings   (which  shall  include,   without
        limitation,  suit, attachment prior to judgment,  other attachment,  the
        obtaining of judgment,  execution or other enforcement) shall be claimed
        by or on behalf of the Lessee or with respect to its assets, irrevocably
        waives any such right of immunity which it or its assets now have or may
        hereafter  acquire  or which may be  attributed  to it or its assets and

<PAGE>

        consents generally in respect of any such legal action or proceedings to
        the giving of any relief or the issue of any process in connection  with
        such action or proceedings  including,  without limitation,  the making,
        enforcement or execution against any property  whatsoever  (irrespective
        of its use or intended  use) of any order of judgment  which may be made
        or given in such action or proceedings.

26.     SECTION 1110

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

        It is  expressly  agreed  that the  title  of Head  Lessor  to,  and the
        interest of the Lessor and the  Beneficiary  to, and the interest of the
        Lessor and the Beneficiary in, the Aircraft, and any right of the Lessor
        and the  Beneficiary  to take  possession  of the Aircraft in compliance
        with the provisions of this Agreement, shall not be affected by Sections
        362, 363 and 1129 of the Federal Bankruptcy Code.

27.     TRUE LEASE

        THIS  AGREEMENT  SHALL  CONSTITUTE  AN  AGREEMENT OF LEASE AND IS A TRUE
        OPERATING  LEASE AND NOTHING  HEREIN  SHALL BE CONSTRUED AS CONVEYING TO
        THE LESSEE ANY RIGHT, TITLE OR INTEREST IN THE AIRCRAFT OR ANY ENGINE OR
        PART EXCEPT AS A LESSEE ONLY. WITHOUT LIMITING THE FOREGOING, THE LESSEE
        WILL  NOT  FILE  A  TAX  RETURN  OR  TAKE  ANY  OTHER  ACTION  WHICH  IS
        INCONSISTENT WITH THE FOREGOING.

                                 LEASE AGREEMENT
                                   (MSN 28869)

LEASE AGREEMENT (MSN 28869), dated as of June 27, 1997 (this "Lease Agreement"),
between BOULLIOUN PORTFOLIO FINANCE I, INC. ("Lessor") and WESTERN PACIFIC
AIRLINES, INC. ("Lessee").

                                    RECITALS:

Lessor has agreed,  simultaneously  herewith,  to acquire the Aircraft (this and
all other capitalized terms used herein shall have the respective meanings,  and
shall be interpreted  and construed in the manner,  set forth in Section 1) from
Airframe  Manufacturer  pursuant to the  Novation  Agreement  for the purpose of
leasing the Aircraft to Lessee.

Lessee desires, upon the terms and conditions hereof, to lease the Aircraft from
Lessor,  and Lessor is willing,  upon the terms and conditions  hereof, to lease
the Aircraft to Lessee.

                                   AGREEMENT:

In  consideration  of the  foregoing  premise,  and for other good and  valuable
consideration  the  adequacy and receipt of which are hereby  acknowledged,  the
parties hereto agree as follows:

      SECTION 1.  DEFINITIONS; CONSTRUCTION AND INTERPRETATION

      The  capitalized  terms  used in  this  Lease  Agreement  shall  have  the
respective  meanings  ascribed  thereto in Schedule 1. The rules of construction
and interpretation that apply to this Agreement are set forth in Section 19.1.

      SECTION 2.  LEASE OF AIRCRAFT

           2.1  Agreement to Lease

           Subject to satisfaction of the conditions set forth in Schedule 6 and
to the  provisions  of this  Section 2,  Lessor  hereby  agrees to  deliver  the
Aircraft to Lessee at the Delivery Location and to lease the Aircraft to Lessee,
and Lessee hereby agrees to accept the Aircraft at the Delivery  Location and to
lease the Aircraft from Lessor, in each case, on the Scheduled Delivery Date and
in the condition delivered to Lessor by Airframe Manufacturer under the Novation
Agreement,  but  otherwise in the "as is, where is"  condition of the  Aircraft,
pursuant  to the terms and  conditions  of this  Lease  Agreement  and the other
Operative  Documents,  the  commencement  of such leasing to be evidenced by the
execution  and delivery by Lessee to Lessor of, and the  confirmation  by Lessor
of, the Acceptance Certificate.

                                       1
<PAGE>

           2.2  No Right to Refuse

           Lessee  acknowledges  that Lessor has agreed to purchase the Aircraft
pursuant to the Novation  Agreement for the sole purpose of leasing the Aircraft
to Lessee  pursuant to this Lease  Agreement.  Accordingly,  Lessee shall not be
entitled for any reason  whatsoever to refuse to accept delivery of the Aircraft
under  this  Lease  once the  Aircraft  has been  accepted  by Lessor  under the
Novation Agreement and, without limiting the effect of Section 5.1, Lessor shall
not be liable for any loss or expense, or any loss of profit, resulting directly
or  indirectly  from any defect or alleged  defect in the Aircraft or failure or
alleged failure of the Aircraft to comply with the  requirements of the Novation
Agreement.  As between Lessor and Lessee,  Lessee shall have sole responsibility
for ensuring that the Aircraft is in the condition on the Delivery Date required
by the  Airframe  Manufacturer  Purchase  Agreement  (as defined in the Novation
Agreement).

     2.3 Changes in Delivery Date;  Limitation of Lessor's Obligation to Deliver
        Aircraft

           If,  owing  to (1)  any  of the  conditions  precedent  specified  in
Schedule 6 not having been met or not having been waived by Lessor in accordance
with  Schedule 6, (2) any delay in the delivery  of, or failure to deliver,  the
Aircraft to Lessor for  whatsoever  reason and/or (3) reasons of Force  Majeure,
the delivery of the Aircraft under this Lease  Agreement shall be delayed beyond
the Scheduled  Delivery Date,  then Lessee shall accept delivery of the Aircraft
on the first  Business  Day after such date on which no Force  Majeure  prevents
such delivery,  Lessor has  possession of the Aircraft at the Delivery  Location
and all of such conditions precedent have been satisfied or waived in accordance
with  Schedule 6,  provided  that if delivery of the  Aircraft  under this Lease
Agreement is delayed beyond the Commitment  Termination  Date, then either party
hereto  (so long as such  party is not in  default  hereunder)  may,  by written
notice to the other,  terminate  this Lease  Agreement and each other  Operative
Document (including the Novation Agreement), whereupon neither Lessor nor Lessee
shall have any further  obligation to the other hereunder or thereunder,  except
as otherwise  expressly  provided herein or therein and except that Lessor shall
be obligated to return the Security  Deposit and/or the Letter of Credit and any
amounts of Basic Rent paid by Lessee  prior to such  termination  (in each case,
free and clear of Liens other than Lessee Liens). In the event of any such delay
or any eventual  termination of this Lease Agreement,  neither Lessor nor Lessee
shall be responsible for any losses, including loss of profit, costs or expenses
arising  therefrom  suffered  or  incurred  by the  other.  Notwithstanding  the
foregoing,  (y) if such delay or failure  is caused by a Default,  Lessor  shall
have all the  rights and  remedies  against  Lessee  described  in  Section  13,


                                       2
<PAGE>

including the right to collect damages for Expenses in connection with any delay
in delivery of the  Aircraft,  and Lessor  shall not be  obligated to return the
Security  Deposit or the  Letter of Credit or any  amounts of Basic Rent paid by
Lessee  (except to the extent not  applied,  drawn and  applied  and/or  used as
setoff by Lessor  pursuant  hereto)  and (z) if  Lessor  shall  delay or fail to
deliver the Aircraft in breach of its  obligations  hereunder or under the other
Operative Documents, Lessee shall have all rights provided by Law arising out of
such breach, including the right to terminate this Lease Agreement and the other
Operative Documents.

      SECTION 3.  LEASE TERM; RENT; PAYMENTS

           3.1  Basic Lease Term

           The Basic Lease Term shall commence on the Delivery Date and,  unless
this Lease Agreement is terminated  earlier  pursuant to the provisions  hereof,
shall  end on the  Basic  Lease  Term  Termination  Date,  provided  that if the
scheduled last day of the Basic Lease Term shall not be a Business Day, then the
Basic Lease Term shall expire on the next preceding Business Day.

           3.2  Renewal Lease Term

           Lessee  shall  have the  option  to extend  the Lease  Term up to two
times, with each such extension to be for a one year period.  Such option may be
exercised  only by delivery  of (1) a Renewal  Rent  Determination  Request on a
timely basis (as provided below) and (2) written irrevocable notice to Lessor at
least 6 months prior to the then scheduled expiration of the Lease Term electing
to extend the Lease Term by one year, provided that Lessee may not exercise such
option at any time when an Event of Default has occurred and is continuing. Each
Renewal Lease Term shall commence on last day of the Lease Term (without  regard
to such Renewal Lease Term) and end on the Renewal Lease Term Termination  Date,
provided  that if the last day of a Renewal  Lease  Term shall not be a Business
Day,  then such Renewal Lease Term shall expire on the next  preceding  Business
Day.

           Upon written  request (a "Renewal Rent  Determination  Request") from
Lessee to Lessor at least 8 months but no more than 10 months  prior to the then
scheduled  expiration  of the Lease Term,  Lessor and Lessee shall in good faith
and acting reasonably determine the Renewal Rent Amount. If 15 days prior to the
Renewal Rent Determination  Date, Lessor and Lessee cannot determine the Renewal
Rent Amount,  then the Renewal Rent Amount shall be determined by two recognized
independent  aircraft  appraisers,  one of which shall be selected by Lessee (at
its expense) and one of which shall be selected by the Lessor (at its  expense),
or if such appraisers cannot agree, by a third  independent  appraiser chosen by
the  mutual  assent  of the first two  appraisers  (with the cost of such  third


                                       3
<PAGE>

appraiser to be shared equally by Lessor and Lessee). If either party shall fail
to appoint an appraiser at least 11 days prior to the Renewal Rent Determination
Date, or if such two  appraisers  cannot agree on the amount of the Renewal Rent
and fail to appoint a third  appraiser  at least eight days prior to the Renewal
Rent  Determination  Date,  then  Lessor and Lessee  shall  jointly  request the
American  Association of Equipment  Lessors (or any successor  organization)  to
appoint the relevant  appraiser.  Any such third  appraiser  shall determine the
amount of the Renewal Rent on or prior to the Renewal Rent Determination Date.

           3.3  Basic Rent and Renewal Rent

           Lessee  shall pay rent for the Aircraft in  installments  (1) on each
Basic Rent  Payment  Date  during  the Basic  Lease Term equal to the Basic Rent
Amount and (2) on each Renewal  Rent Payment Date during any Renewal  Lease Term
equal to the  Renewal  Rent  Amount,  in each case,  in  advance in  immediately
available Dollars.

           3.4  Supplemental Rent

           Lessee  shall pay,  or cause to be paid,  promptly  to Lessor,  or to
whomsoever shall be entitled thereto,  any and all Supplemental Rent when and as
the same  shall  become due and owing.  Lessee  also shall pay to Lessor,  or to
whomsoever shall be entitled thereto,  on demand,  as Supplemental  Rent, to the
extent  permitted by applicable  Law,  interest at the Past Due Rate on any Rent
(including any interest  accrued thereon  pursuant to this Section 3 (compounded
on a daily  basis))  not paid when due for any  period  for which the same shall
remain unpaid.

           3.5  Payments in General

                3.5.1  Timing and Place of Payment

                All payments of Rent payable to Lessor shall be made directly by
Lessee  in  Dollars  by wire  transfer  of  immediately  available  funds on the
required  date of payment and with value on such date, to the account for Lessor
specified  in Schedule  4, or to such other  account as Lessor  shall  otherwise
direct by prior notice to Lessee.

                3.5.2  Business Day Convention

                If the due date for any  payment of Rent is not a Business  Day,
then,  unless  otherwise  provided  herein,  such  payment  shall be made on the
Business Day next  preceding  such scheduled date with the same force and effect
as if made on such scheduled date and without adjustment in the amount due.

                3.5.3  Calculation of Interest

                All amounts of interest or amounts  calculated  by  reference to
interest  payable  under any of the  provisions  of this Lease  Agreement or any
other  Operative  Document shall be calculated on the basis of the actual number
of days elapsed in a 360-day year.

                3.5.4  Determination by Lessor

                Any determination by Lessor or any other payee as to any rate of
interest,  Rent,  Reserves or any other amount shall, in the absence of manifest
error, be conclusive and binding on Lessee.

                3.5.5  Payments to Lessee

                Any amount  referred to in this Agreement or any other Operative
Document  which is  payable  by  Lessor  to Lessee  or  received  by Lessee  and
expressly  retainable  by Lessee  hereunder  shall not be paid to or retained by
Lessee if at the time of such payment or receipt by Lessee a Default  shall have
occurred  and be  continuing,  but shall be held by or paid over to  Lessor,  as
security  for the  obligations  of Lessee  under  this  Agreement  and the other
Operative  Documents  to be held and applied  pursuant to Section 13 and applied
against  Lessee's  obligations  hereunder as and when due. At such time as there
shall not be continuing any Default,  such amount shall be paid to Lessee to the
extent not applied in accordance with the preceding sentence.

           3.6  Illegality

           If this Agreement  becomes  invalid,  unenforceable or illegal as the
result of any change of Law arising after the date hereof, the parties shall use
reasonable  efforts to modify or amend this  Agreement  so as to render it valid
and legal in all respects.  In the event that it is not possible so to modify or
amend this Agreement within a reasonable  period (which shall not, in any event,
exceed 60 days or such  shorter  period as may be  required  by Law)  Lessor may
terminate  this  Agreement  upon 14 days'  (or  such  shorter  period  as may be
required by Law) notice of termination to Lessee  whereupon Lessee shall deliver
the  Aircraft  to Lessor  in  accordance  with the  provisions  of  Section 3 of
Schedule 2 and, in the absence of a  prohibition  pursuant  to  applicable  Law,
Lessee shall continue to pay Basic Rent and, if applicable,  Renewal Rent to the
end of the Lease Term as specified  herein (but not Reserves or indemnities with
respect to periods after the Return of the Aircraft in accordance with Section 3
of Schedule 2). Upon  compliance by the Lessee with the foregoing,  Lessor shall


                                       5
<PAGE>

return to Lessee the  Security  Deposit  and any  amounts of Basic Rent and,  if
applicable,  Renewal  Rent paid by Lessee to the extent that Lessor has actually
received  rental from any person in respect of the Aircraft  with respect to any
period  for which such Basic Rent and,  if  applicable,  Renewal  Rent was paid.
Lessor shall use reasonable efforts to minimize the amount of Basic Rent and, if
applicable, Renewal Rent to be retained by Lessor.

      SECTION 4.  SECURITY DEPOSIT; LETTER OF CREDIT

           4.1  Payment of the Security Deposit

           Lessor  acknowledges  to  Lessee  that it has  received  the  Initial
Security  Deposit.  Unless  Lessee  shall have  exercised  its option to provide
Lessor a Letter of Credit pursuant to Section 4.4 of the Lease Agreement, Lessee
shall pay to Lessor,  by wire transfer of immediately  available  Dollars to the
account of Lessor  specified in Schedule 4 on or before the date both Lessor and
Lessee sign this Agreement, the Documentation Security Deposit Installment.

           All such  amounts,  as held by Lessor or Security  Agent from time to
time, are referred to in this Lease Agreement and the other Operative  Documents
as the "Security Deposit."

           4.2  Lessor's Interest in Security Deposit

           The Security  Deposit shall secure the timely payment and performance
by Lessee  of (1) its  obligations  hereunder  and under  each  other  Operative
Document and (2) its  obligations  under each of the Other Leases and under each
of the "Operative Documents" (howsoever denominated) related to the Other Leases
(such   documents  and  agreements   referred  to  in  subclause  (1)  and  (2),
collectively,  the "Transaction  Documents" and such obligations  referred to in
subclause (1) and (2), collectively,  the "Secured Obligations").  Lessee hereby
assigns,  transfers  and  pledges to  Lessor,  and  hereby  grants to Lessor,  a
first-priority  security interest in the Security Deposit to secure such payment
and such  performance.  Lessee shall not assign,  transfer,  pledge or otherwise
dispose of any right,  title or interest in or to the Security Deposit except as
provided in the  preceding  sentence.  Subject only to Sections 2.3 and 4.3, the
Security  Deposit  may be  assigned  or  pledged  by Lessor to any  Person.  The
Security  Deposit may be commingled by Lessor or such other Person,  as the case
may be, with its own general or other funds during the Lease Term.  Any interest
earned on the  Security  Deposit  shall be for  Lessor's or such  Person's  sole
account.  If an Event of Default  (hereunder  or under any of the Other  Leases)
shall occur and be  continuing,  then in addition to any other rights Lessor may
have  under  applicable  Law as a  secured  party or  otherwise,  or under  this
Agreement or any other Transaction Document,  Lessor or such Person, as the case
may be,  may at any time as an agreed  remedy  set off  against,  use,  apply or
retain all or any portion of the Security Deposit in full or partial payment for


                                       6
<PAGE>

amounts constituting the Secured Obligations  (including to compensate Lessor or
such  Person,  as the  case  may be,  for any  amount  it may in its  reasonable
discretion  advance as a result of the  occurrence of any Default  (hereunder or
under any of the Other Leases),  or to apply toward Expenses arising as a result
of the occurrence of any Default (hereunder or under any of the Other Leases) or
otherwise).  If Lessor or such  Person  uses or applies  all or a portion of the
Security  Deposit,  such  application  shall not be deemed a cure by Lessee,  or
waiver by Lessor or any other Person, of any Default (hereunder and under any of
the Other  Leases),  and Lessee  shall,  within ten days after  Lessor's or such
Person's demand therefor,  pay to Lessor or such Person,  as the case may be, an
amount sufficient to restore the Security Deposit to its required total sum.

           4.3  Return of Security Deposit

           That portion, if any, of the Security Deposit that has not previously
been used or applied,  or set off against,  as provided for in this Agreement or
any other  Operative  Document,  shall be returned to Lessee  (free and clear of
Liens other than Lessee Liens) by wire transfer of immediately available Dollars
to Lessee's account  specified in Schedule 4, or to such other account as Lessee
shall  specify  in  writing  to  Lessor,  on the date  which is not more than 10
Business  Days after and  excluding the date upon which the Aircraft is returned
to Lessor in  accordance  with this Lease  Agreement so long as no Default shall
have occurred and be continuing at such time.

           4.4  Substitution of Letter of Credit

           Lessee shall have the one-time  irrevocable  option to substitute for
the Security  Deposit a letter of credit (a "Letter of  Credit"),  in respect of
all of the Secured Obligations,  with a stated amount equal to the amount of the
Security  Deposit  required as of the Delivery  Date. The Letter of Credit shall
(1)  be in the  form  of  Exhibit  G,  (2)  be  issued  or  confirmed  by a bank
satisfactory  to Lessor and (3) have an expiry date of no earlier  than the date
one month after the Scheduled Return Date (upon request of Lessee,  Lessor shall
consider  accepting a one-year (or longer period) rolling letter of credit).  In
the event that at any time during the Lease Term the bank issuing or  confirming
the Letter of Credit becomes unacceptable to Lessor, in its reasonable judgment,
Lessee shall within  fourteen days of demand  therefor by Lessor  provide Lessor
with a replacement letter of credit issued or confirmed,  as the case may be, by
a bank that is acceptable to Lessor, in its reasonable  judgment.  The Letter of
Credit may be  assigned  or pledged by Lessor to any  Person.  If for any reason
Lessor or such other Person is paid under the Letter of Credit, then in addition
to any other  rights  Lessor or such  Person may have under  applicable  Law, or
under this Lease  Agreement or any other  Transaction  Document,  Lessor or such
Person,  as the case may be,  (1) may at any time as an  agreed  remedy  set off


                                       7
<PAGE>

against,  use, apply or retain all or any portion of the amounts so paid in full
or partial payment for amounts  constituting the Secured Obligations  (including
to compensate  Lessor or such Person,  as the case may be, for any amount it may
in its  reasonable  discretion  advance  as a result  of the  occurrence  of any
Default  (hereunder  or under  any of the  Other  Leases),  or to  apply  toward
Expenses  arising as a result of the  occurrence  of any Default  (hereunder  or
under any of the Other  Leases) or  otherwise)  and/or (2) may retain all or any
portion of the  amounts so paid as  security  for the  performance  the  Secured
Obligations  (and Lessee hereby  grants  Lessor a security  interest in all such
amounts).  Any such use or application shall not,  however,  be deemed a cure by
Lessee,  or waiver by Lessor or any Person,  of any Default  (hereunder or under
any of the Other Leases).  Any interest  earned on the amounts so drawn shall be
for Lessor's or such other Person's sole account.  If for any reason,  Lessor or
such other  Person is paid under a Letter of Credit,  then Lessee shall cause an
additional  Letter of Credit  (which  shall become the "Letter of Credit") to be
issued  so that the  Lessor or such  other  Person  shall at all times  have the
benefit of a Letter of Credit for the full Security  Deposit required under this
Section 4.4.

           4.5  Return of Letter of Credit

           So long as no Default  shall have  occurred and be continuing at such
time,  the Letter of Credit,  unless  drawn by Lessor and no longer in  Lessor's
possession, and any then unapplied cash proceeds from a drawing of the Letter of
Credit shall be returned to Lessee at its address set forth in Schedule 4 on the
date which is not more than 10 Business  Days after and  excluding the date upon
which the Aircraft is returned to Lessor in accordance with this Agreement.

           4.6  Release of Boullioun Aviation Services, Inc.

           For the  benefit  of Lessor  and its  Affiliate,  Boullioun  Aviation
Services,  Inc., upon payment of the same by Boullioun Aviation Services Inc. to
Lessor,  Lessee  confirms that it shall have no further claim against  Boullioun
Aviation  Services  Inc.  for, and Lessee  hereby  releases  Boullioun  Aviation
Services,  Inc.  from any further  obligation  or  liability  in respect of, the
Initial Security Deposit Installment.

                Lessor  hereby  covenants  to Lessee that so long as no Event of

provided in this Lease Agreement or any other Operative Document, neither Lessor

holder,  any right,  title or interest in any engine  covered by any such lease,
conditional  sale  or  security  agreement,  which  engine  is  attached  to the
Airframe, provided that such agreement of Lessor shall not be for the benefit of
any lessor, seller or security interest holder of any such airframe, unless such
lessor, seller or security interest holder has expressly agreed (which agreement
may  be  contained  in  such  lease,  conditional  sale  agreement  or  security
agreement)  that  neither it nor its  successors  or assigns  will  acquire,  as
against  Lessor,  any right,  title or interest in an Engine as a result of such
Engine's being installed on such airframe.

operations (Lessor
and Lessee agree that a labor stoppage or strike or any suspension of operations

in itself constitute a discontinuance of business).

     Consolidate with or merge into any other  corporation,  or permit any other
corporation to  consolidate  with or merge into Lessee,  or convey,  transfer or

entirety to any Person if:

     6.2.1.3.2  Such  Successor (if not the Lessee) shall execute and deliver to
Lessor an  agreement in form and  substance  reasonably  satisfactory  to Lessor
containing an assumption by such  Successor of the due and punctual  performance

substantially all of the assets of Lessee as an entirety in accordance with this
Section 6.2.1.3, the Successor shall succeed to, and be substituted for, and may
exercise  every right and power of,  Lessee under this Lease  Agreement  and the
other  Operative  Documents  with the same effect as if such  Successor  or such
Person had been named as Lessee herein and therein. No such conveyance, transfer
or lease of substantially  all of the assets of Lessee as an entirety shall have
the effect of releasing  Lessee,  or any Successor which shall  theretofore have
become such in the manner prescribed in this Section 6.2.1.3, from its liability
hereunder  or under any other  Operative  Document  to which  Lessee is a party.
Nothing  contained herein shall permit any lease,  sublease or other arrangement

under any of the Operative  Documents or otherwise by any other Person, and such
Indemnified  Party may proceed  directly  against  Lessee  under this  Section 9
and/or  Schedule  5  without  first  resorting  to  any  such  other  rights  of
indemnification, guarantee or insurance.
                9.5.2 All  indemnities,  obligations,  adjustments  and payments
provided  for in this  Section 9 and  Schedule  5 shall,  to the  extent  herein
provided,  survive  and remain in full  force and  effect,  notwithstanding  the
expiration or  termination  of the Lease Term or of this Lease  Agreement or any
other Operative  Documents and the payment in full of all sums payable under the


                                       29
<PAGE>

Operative  Documents.   The  obligations  of  Lessee  in  respect  of  all  such
indemnities,  obligations,  adjustments  and payments are expressly made for the
benefit of, and shall be enforceable by, the Indemnified Party entitled thereto,
without  declaring this Lease  Agreement to be in default or taking other action
under this Lease Agreement or any other Operative Document.

                9.5.3 Lessee  acknowledges that the Indemnified  Parties, or any
of them,  may authorize  Lessor,  by notice in writing to Lessor and Lessee,  to
make  claims  and  demands  under  any  indemnity  hereunder  or under any other
Operative  Document on behalf of such Indemnified  Parties,  and Lessee shall be
obligated to make all payments  pursuant to any such indemnity to Lessor, to the
extent  claimed  by  Lessor  on behalf  of such  Indemnified  Parties  (it being
understood  that Lessee is entitled  to, and shall,  conclusively  rely upon the
instructions  of Lessor  with  respect to the  payment  of amounts  owing to any
Indemnified Party under the indemnities).

                9.5.4 Each Indemnified Party and Lessee will give prompt written
notice one to the other of any  liability of which such party has  knowledge for
which Lessee is, or may be, liable under  Section 9.1,  provided that failure to
give such notice will not prejudice or otherwise affect any of the rights of the
Indemnified Parties under Section 9.1.

                9.5.5  This  Agreement,  insofar  as it  provides  rights  to an
Indemnified  Party or Tax  Indemnitee,  constitutes  a separate  agreement  with
respect to each such Person and is enforceable directly by each such Person.

                9.5.6 Lessee will provide the relevant  Indemnified Party or Tax
Indemnitee with such information not within the control of such Person, as is in
Lessee's  control or is  reasonably  available to Lessee,  which such Person may
reasonably request and Lessee will otherwise cooperate with such Person so as to
enable such Person to defend any action, suit or proceeding brought against such
Person for which  Lessee is  responsible  under this  Section 9,  provided  that
nothing  contained  in this Section 9 shall be deemed to require any such Person
to  contest  any  Expense  or to assume  responsibility  for or  control  of any
judicial proceeding with respect thereto.

                9.5.7 The  obligations of Lessee in respect of all  indemnities,
obligations,  adjustments  and payments in this Section 9 are expressly made for
the benefit of, and shall be enforceable  by, the Indemnitee  entitled  thereto,
without declaring the Lease to be in default or taking other action hereunder.

           9.6  Indemnities Payable on After-Tax Basis

           Lessee  agrees  that,  with respect to any payment or indemnity to an
Indemnified Party or Tax Indemnitee under this Section 9 or Schedule 5, Lessee's
payment or indemnity  obligations shall be increased by an amount, if any, which
shall be necessary to hold such  Indemnified  Party or Tax  Indemnitee  harmless
from all Taxes required to be paid by such  Indemnified  Party or Tax Indemnitee
with respect to the receipt or accrual of such  payment or indemnity  (including
any payment by such Indemnified  Party or Tax Indemnitee of any Taxes in respect
to any  indemnity  payments  received  or  receivable  under  this  Section 9 or
Schedule 5).

      SECTION 10.  RISK OF LOSS, DESTRUCTION AND REQUISITION, ETC.

           10.1  Risk of Loss

           Throughout the Lease Term and until the Return, Lessee shall bear all
risk of loss,  damage,  theft or destruction of, or any other Event of Loss with
respect to, the Aircraft, the Airframe, each Engine and each Part.

           10.2  Event of Loss With Respect to the Aircraft

                10.2.1 Upon the  occurrence  of an Event of Loss with respect to
the Airframe or the Airframe and Engines,  Lessee shall  forthwith  (and, in any
event,  within three days after such  occurrence) give Lessor and Security Agent
written  notice of such Event of Loss.  By the  earlier of (1) 60 days after the
occurrence  of  such  Event  of Loss or (2) the  date on  which  the  applicable
insurance or requisition proceeds are paid, Lessee shall pay or cause to be paid
to Lessor in immediately  available funds the Stipulated Loss Value (but only to
the extent the full amount of the  Stipulated  Loss Value was not  obtained  and
applied by Lessor  pursuant  to Section  11.2.1 or  received  by Lessor from the
relevant Government Entity in connection with any requisition).

                10.2.2 Until the date on which the Stipulated Loss Value is paid
in full,  Lessee  shall be  obligated  to pay all Basic Rent and Renewal Rent as
scheduled and shall continue to perform all of its other  obligations  hereunder
and  under  the  other  Operative  Documents,  except  to  the  extent  rendered
impossible by the  occurrence of such Event of Loss or rendered,  in the opinion
of Lessor,  unnecessary.  If the  Stipulated  Loss Value is paid on a date other
than a Rent Payment Date,  Lessor shall refund or cause to be refunded to Lessee
any paid (but  unaccrued on such date) Basic Rent or Renewal Rent.  Upon receipt
of the full  amount of the  Stipulated  Loss  Value by Lessor  pursuant  to this
Section  10.2,  and if Lessee has paid all other amounts then due and payable by
Lessee under this Lease  Agreement and the other Operative  Documents,  then (1)


                                       31
<PAGE>

Lessor shall,  upon the joint  written  request of Lessee and each insurer which
contributed to the payment of the Stipulated Loss Value,  transfer to the Person
designated in such request title to the Aircraft  (including the Engines and all
Parts)  without  recourse  or  warranty  (except  as to absence of all rights of
Lessor and all Lessor Liens) and subject to the  disclaimer set forth in Section
5.1, (2) Lessor shall return to Lessee the Security Deposit or Letter of Credit,
as applicable, and any insurance, requisition,  condemnation or similar proceeds
received  after and  related to such  Event of Loss in excess of the  Stipulated
Loss Value and all Reserves previously paid by Lessee in respect of the Aircraft
(in each case, to the extent not previously applied in accordance with the terms
hereof) and (3) Lessee  shall be relieved  of its  obligations  under this Lease
Agreement  and the other  Operative  Documents  except those that are  expressly
stated to survive termination hereof and thereof.

           10.3  Event of Loss With Respect to an Engine

                10.3.1 Upon the  occurrence  of an Event of Loss with respect to
an Engine under  circumstances  in which there has not occurred an Event of Loss
with respect to the Airframe,  Lessee shall promptly (and, in any event,  within
three days after such  occurrence) give Lessor and Security Agent written notice
thereof  and  shall,  promptly  and,  in any  event,  within  90 days  after the
occurrence  of such Event of Loss (or,  if  earlier  the date of  expiration  or
termination of the Lease Term) and upon five days' prior written notice,  convey
or cause to be conveyed to Lessor, as replacement for the Engine with respect to
which such Event of Loss occurred, title to a Replacement Engine, free and clear
of all Liens (other than Permitted  Liens).  For all purposes hereof,  each such
Replacement Engine shall, after such conveyance,  be deemed part of the property
leased hereunder, and shall be deemed an "Engine."

                10.3.2  Prior  to  or  at  the  time  of  any  conveyance  of  a
Replacement  Engine,  Lessee shall, at its own expense,  comply with each of the
following requirements:

                      10.3.2.1 Furnish Lessor with a full warranty bill of sale,
in form and substance
satisfactory to Lessor, conveying to Lessor such Replacement Engine.

                      10.3.2.2 Execute one or more lease supplements  subjecting
such Replacement Engine to this
Lease Agreement.

     10.3.2.3  Without  limiting the  obligations of Lessee under Section 7.2.3,
cause the filing of such  instruments,  in form and  substance  satisfactory  to
Lessor,  as are necessary or advisable to establish and protect the interests of
Lessor  and the  Financing  Parties  in any such  Engine  (including  such lease
supplements).

                      10.3.2.4 Furnish Lessor with such evidence of the transfer
of title to such Replacement
Engine  to  Lessor  as  Lessor  may  reasonably  request,  including  that  such
Replacement Engine is free and clear of all Liens,  except Permitted Liens, such
evidence  to  include,  without  limitation,  an  opinion  of  Lessee's  counsel
addressed  to Lessor and opining  that such title has been so conveyed  and that
such Replacement Engine has been duly subjected to this Lease Agreement.

     10.3.2.5   Furnish  Lessor  with  such  evidence  of  compliance  with  the
provisions  of Sections 1.5 and 1.7 of Schedule 2 and Section 11 with respect to
such Replacement Engine as Lessor may reasonably request.

                      10.3.2.6  [Intentionally Left Blank]

warranties with respect to such Replacement  Engine pursuant to an assignment in
form and substance reasonably acceptable to both parties.

                      10.3.2.8  [Intentionally Left Blank]

                      10.3.2.9  Furnish  Lessor with a  certificate  signed by a
duly authorized officer of Lessee
certifying that, upon  consummation of such  replacement,  no Default will exist
hereunder.

                      10.3.2.10 Furnish Lessor with an appraisal satisfactory to
Lessor which shall establish,
and a  certificate  of an aircraft  engineer  (who may be an employee of Lessee)
certifying,  that  such  Replacement  Engine  complies  with the  definition  of
"Replacement  Engine"  for  purposes  of this  Lease  Agreement  and each  other
Operative Document.

                10.3.3 Upon  compliance by Lessee with the  requirements of this
Section  10.3,  if no  Payment/Bankruptcy  Default  shall  have  occurred  or be
continuing,  Lessor  shall,  upon the joint  written  request of Lessee and each
insurer which contributed to the payment of any insurance  proceeds with respect
to the lost Engine,  transfer to the Person  designated in such request title to
such Engine without  recourse or warranty (except as to absence of all rights of
Lessor and all Lessor Liens) and subject to the  disclaimer set forth in Section
5.1, and such Engine shall thereupon cease to be an Engine leased hereunder.

                10.3.4 No Event of Loss with  respect to an Engine  shall result
in any reduction in Rent.

                Other than as provided in this  Section  10.3,  Lessee shall not
have the right to substitute any engine for an Engine.

           10.4  Requisition for Use of the Aircraft by any Government Entity

           In the  event  of the  requisition  for use of the  Airframe  and the
Engines  or  engines  installed  on the  Airframe  during  the Lease Term by any
Government  Entity not  constituting  an Event of Loss,  Lessee  shall  promptly
notify Lessor and the Security  Agent of such  requisition,  and all of Lessee's
obligations  under this Lease Agreement and each other  Operative  Document with
respect to the Aircraft shall continue to the same extent as if such requisition
had not occurred. All payments received by Lessor or Lessee from such Government
Entity for the use of such Airframe and Engines or engines during the Lease Term
shall be paid over to, or retained by,  Lessee if no Default shall have occurred
and be  continuing  and all  payments  received  by Lessor  or Lessee  from such
Government  Entity for the use of such Airframe and Engines or engines after the
end of the Lease  Term  shall be paid over to, or  retained  by,  Lessor (to the

insured thereunder.

                                       37
<PAGE>

                11.3.2 During each portion of the two-year period that Lessee is
not the owner or operator of the  Aircraft or any Engine,  Lessee shall carry or
cause to be carried  products  liability  insurance in the amount required under

additional insured thereunder.

pursuant to this  Section 11,  provided  that Lessee may  self-insure  the risks
covered by the hull insurance  maintained in compliance  with this Section 11 by
way of deductible  (except in connection  with a total loss), in such amounts as
are customarily  self-insured with respect to aircraft of the same type and used
in the same manner as the  Aircraft by other  similar  air  carriers,  but in no
event in an amount  greater than the Stipulated  Deductible  Amount per aircraft
per occurrence.

           11.6  Change of Industry Practice

           In the  event  that  there  is a  material  change  in the  generally
accepted industry-wide practice with regard to the insurance of similar aircraft
or any material  change with respect to the insurance of similar  aircraft based
or  operated  in any  jurisdiction  in which the  Aircraft  may then be based or
operated (whether  relating to all or any of the types of insurance  required to
be effected  under this  Section 11),  such that Lessor,  on the basis of advice
received from an  independent  insurance  advisor of  international  reputation,
shall be of the reasonable  opinion that the insurance required pursuant to this
Section 11 is insufficient to protect the respective  interests of Lessor and/or
any other Insured Parties, the insurance  requirements set forth in this Section
11 shall be amended so as to include such  additional or varied  requirements as
Lessor (upon the advice of such  independent  insurance  advisor) may reasonably
consider appropriate.

           11.7  Change of Circumstance

           If at any  time,  Lessor  reasonably  considers  that any  change  in
circumstances is likely to occur, or has occurred and is continuing, which would


                                       38
<PAGE>

materially  affect or is  materially  affecting the insurance of the Aircraft or
Airframe,  then Lessor shall be entitled (without  prejudice to any other rights
which it may  have or  acquire  under  this  Agreement  or any  other  Operative
Document by reason of such change in  circumstances)  to require the Aircraft or
Airframe,  as the case may be, to remain at any  airport  or to  proceed  to and
remain at any airport  designated  by Lessor on the routes flown by Lessee until
Lessee  shall have  supplemented  or  replaced,  or  implemented  any  necessary
amendments to the terms of, such  insurance,  and  implemented  any  operational
changes,  which Lessor  reasonably  considers are required as the result of such
change in  circumstances.  Except in the case of exigent  circumstances,  Lessor
shall give Lessee notice prior to exercising its rights under this section.

           11.8  Negative Undertakings

           Lessee  shall not act or fail to act,  or cause,  permit or suffer an
act or failure to act,  whereby any insurance  required by this Section 11 would
or might  reasonably  be  expected to be limited or rendered in whole or in part
invalid,  unenforceable or otherwise not in full force and effect (including any
limitation  resulting  from  inaccuracy  of any  representation  or  warranty of
Lessee, or any illegal use of the Aircraft).

           11.9  Failure to Insure

           If at any time Lessee fails to maintain  insurance in compliance with
this  Section 11, each of Lessor and  Security  Agent shall be entitled  but not
bound to do any of the following (without prejudice to any other rights which it
may have under this Lease Agreement or any other Operative Document by reason of
such failure):

                11.9.1  To pay any  premiums  due or  effect  or  maintain  such
insurance or otherwise  remedy such failure in such manner as Lessor or Security
Agent, as the case may be,  considers  appropriate (and Lessee shall upon demand
reimburse  Lessor  or  Security  Agent,  as the  case  may be,  in full  for any
reasonable amount so expended) and/or

                11.9.2 At any time while such failure is continuing, require the
Aircraft  to remain at any airport  or, as the case may be,  upon  provision  by
Lessor or Security Agent, as the case may be, of insurance coverage satisfactory
to Lessee, proceed to and remain at any airport designated by Lessor or Security
Agent,  as the case may be,  until such  failure is  remedied  to  Lessor's  and
Security Agent's satisfaction.

           11.10  Additional Insurance

           Lessee  acknowledges  that  Lessor has an  insurable  interest in the
Aircraft.  Lessor shall have the right to obtain  insurance in its own name with
respect to such  insurable  interest.  Lessee will render Lessor all  reasonable
assistance  requested by Lessor in order that Lessor may adequately protect such
insurable  interest.  Lessee agrees that the maximum amounts payable to it or to
others for its account or to be applied in discharge of its  obligations  by any
underwriter or carrier of insurance  maintained by Lessee upon the occurrence of
an Event of Loss with respect to the Aircraft shall be limited to the Stipulated
Loss Value unless the  maintenance  of any such insurance in an amount in excess
of such Stipulated Loss Value in respect of Lessee's  insurable  interest in the
Aircraft does not prejudice  Lessor's  interests under the insurances  otherwise
required by this Section 11, or prevent Lessor from obtaining such insurances as
it requires,  in which event nothing  herein shall prevent Lessee from effecting
such additional insurance for its account. At Lessor's request, Lessee will have
any such additional  insurance coverage for the Aircraft amended so as to cover,
in addition,  Lessor's insurable interest therein, provided that Lessor, in such
case,  reimburses  Lessee in the amount of the  additional  premium  required to
provide such coverage for such insurable interest of Lessor.

           11.11  Insurance Required by Airframe Manufacturer

           Without  limiting  any other  provision  of this  Section 11,  Lessee
hereby assumes and undertakes to perform (to the exclusion of Lessor), and shall
comply with, the indemnity obligations of "Buyer" and the insurance requirements
applicable  to "Buyer"  under Part E to Exhibit C of the  Airframe  Manufacturer
Purchase Agreement as if Lessee were originally named "Buyer" therein.

      SECTION 12.  EVENTS OF DEFAULT

      A  fundamental  term and  condition of this  Agreement is that none of the
following  events shall occur during the Lease Term and that the  occurrence  of
any of the following events shall constitute an "Event 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 Government Entity):

           12.1  Failure to Pay Scheduled Amounts

           Lessee shall have failed to make any periodic or scheduled payment in

      SECTION 13.  REMEDIES

      Upon the  occurrence of any Event of Default and so long as the same shall
be continuing,  Lessor shall have the right, effective upon notice to Lessee, to
terminate this Lease Agreement and each other Operative Document and at any time
thereafter  Lessor may do all or any of the following,  at its option and in its
sole  discretion (in addition to such other rights and remedies which Lessor may
have under applicable Law):

           13.1  Retake Possession

           Upon the  written  demand of Lessor and at  Lessee's  expense,  cause
Lessee to return promptly,  and Lessee shall return  promptly,  the Airframe and
Engines  or such part of the  Aircraft  as Lessor may so demand to Lessor or its
order in the manner and condition  required by, and otherwise in accordance with
all the  provisions  of, Section 3 of Schedule 2 as if such Airframe and Engines
or such part of the Aircraft were being  returned at the expiration of the Lease
Term, or Lessor at its option, may enter upon the premises where the Airframe or
an Engine, or such part of the Aircraft is located and take immediate possession
of and remove  the same  (together  with any  engine  which is not an Engine but
which is  installed  on the  Airframe,  subject  to all the rights of the owner,
lessor,  lienor or secured  party of such engine,  and such engine shall be held
for the account of any such owner, lessor,  lienor or secured party or, if owned
by Lessee,  may, at the option of Lessor, be exchanged with Lessee for an Engine
as if the original Engine had suffered an Event of Loss) by summary  proceedings
or otherwise,  and Lessee waives any right it may have under applicable Law to a
hearing prior to  repossession  of the Aircraft,  Airframe or any Engine or part
(and/or, at Lessor's option,  store the same at Lessee's premises until disposal
thereof by Lessor),  all without liability (except for Lessor's gross negligence
or  willful  misconduct)  accruing  to Lessor  for or by reason of such entry or
taking of  possession  or  removing  whether  for the  restoration  of damage to
property caused by such action or otherwise, and Lessor is hereby irrevocably by
way of security for Lessee's  obligations  under this Lease Agreement  appointed
attorney  for Lessee in causing the  redelivery  or in  directing  the pilots of
Lessee or other pilots to fly the Aircraft to the  designated  location and will
have all the powers and  authorizations  necessary  for taking that  action.  It
shall  be  deemed  to be an  "unlawful  act,"  under  Article  3(2) of the  Rome
Convention,  for Lessee to retain  possession of the  Aircraft,  Airframe or any
Engine or part after Lessor  shall have issued any written  demand for Lessee to
return the same pursuant to this Section 13.1.

           13.2  Termination or Enforcement

           Rescind  this  Lease  Agreement  and any  other  Operative  Document,
terminate this Lease Agreement and any other Operative  Document and/or exercise
any other right or remedy which may be available to it under  applicable  Law or
proceed by appropriate  court action to enforce the terms hereof and/or exercise
any other power,  right or remedy which may be available to Lessor  hereunder or
under  applicable Law.  Without  limiting the generality of the foregoing Lessor
shall have the right,  without need of any consent,  authorization  or action of
Lessee, to cause the Aircraft to be deregistered by the Aviation Authority,  and
to be made ready for export and to be exported  out of the Lessee  Jurisdiction,
and to cause all  rights of Lessee in  respect  of the  Aircraft  and this Lease
Agreement  and each other  Operative  Document  under or in  connection  with or
resulting  from the  registration  of the  Aircraft  or the  recordation  of the
Operative  Documents  with  the  Aviation  Authority  or  otherwise  under or in
connection  with or  resulting  from any Law in the Lessee  Jurisdiction,  to be
terminated and  extinguished.  In furtherance of the foregoing,  Lessor shall be
entitled  and  empowered to act in the name and in the place of Lessee as may be
necessary or desirable,  in Lessor's sole discretion,  including with respect to
the  execution  of documents  and  instruments,  to effect such  deregistration,
derecordation,   exportation,  termination  and  extinguishment.  Lessee  hereby
irrevocably  and by  way of  security  for  its  obligations  under  this  Lease
Agreement   appoints   Lessor  as  its  attorney  to  execute  and  deliver  any
documentation  and to do any  act or  thing  required  in  connection  with  the
foregoing.

           13.3  Application of Funds

           Without  limiting any other  provision of this Lease  Agreement or of
any other  Operative  Document (but subject to Sections 4.3 and 4.5),  Lessor or
Security  Agent shall have the right to continue  to hold the  Security  Deposit
and/or Letter of Credit,  as the case may be, and any other amounts  received or
held as  security  for  Lessee's  obligations  hereunder  and  under  any  other
Operative  Document,  and to withhold  or set off against all amounts  otherwise
payable  to  Lessee  hereunder  or under any other  Operative  Document  (all as
security for Lessee's obligations and liabilities under this Lease Agreement and
the other  Operative  Documents) and to use and apply in whole or in part any or
all of such amounts,  withholdings  and setoffs to and against such  obligations
and liabilities of Lessee (in whatever order and according to whatever  priority
Lessor or  Security  Agent,  as the case may be may  choose),  and any such use,
application or setoff shall be absolute, final and irrevocable.

           13.4  Damages

           In  addition to Lessor's  rights  under  Section  9.1,  recover  from
Lessee, and Lessee shall on demand pay damages to equal the sum of:

                13.4.1 All accrued and unpaid Rent payable  hereunder in respect
of any period  prior to Return of the  Aircraft to Lessor in the  condition  and
otherwise in the manner required under Section 3 of Schedule 2.

                13.4.2 All Expenses  incurred by Lessor in connection  with such
Event of Default or the  exercise of Lessor's  remedies  with  respect  thereto,
including  (1) all costs and expenses  incurred in  connection  with  recovering
possession  of the Airframe or any Engine or in placing such  Airframe or Engine
in the  configuration,  condition and repair required by Section 3 of Schedule 2
and all lost Rent payments during such recovery and  reconditioning  and (2) all
damages  incurred by Lessor in connection with such Event of Default,  including
all losses  (including  reasonable  lost profits)  suffered by Lessor because of
Lessor's  inability to place the Aircraft on lease with another  lessee on terms
as favorable to Lessor as this Lease Agreement or because  whatever use, if any,
to which  Lessor is able to put the Aircraft  upon its return to Lessor,  or the
amount received by Lessor upon a sale or other disposal of the Aircraft,  is not
as profitable to Lessor as leasing the Aircraft in accordance  with the terms of
this Lease Agreement would have been, including in each case, lost Rent payments
during any remarketing period.

      SECTION 14.  ASSIGNMENT OF LEASE

              14.1  Assignment by Lessor

              14.1.1  Right to Assign

                Lessor (and any  subsequent  permitted  assignee or  transferee)
shall  have the  right at any time to  transfer,  assign  (including  assign  as
security),  mortgage,  grant  participations in, or otherwise dispose of, all or
any portion of its right,  title and interest in and to this Lease Agreement and
any other  Operative  Document  and the  Aircraft  to any Person  (including  in
connection  with any conversion of the lease  transaction  contemplated  by this
Lease  Agreement to a  "leveraged  lease"  structure  or a  "headlease-sublease"
structure  with a new  headlease  which may be either a  "leveraged  lease" or a
"single-investor  lease").  The foregoing  right of Lessor is subject (1) in the
case of an Absolute Transfer (as defined below), to Lessor's compliance with the
requirements of Section 14.1.3 or absent such compliance, to receipt of Lessee's
consent (such consent not to be unreasonably  withheld) and (2) in all cases, to
Lessee  receiving from the transferee or assignee a covenant of quiet  enjoyment
substantially in the form of Section 6.1.1.

                                       46

                14.1.2  Cooperation and Limitations

                Lessee shall comply,  at Lessor's  expense,  with all reasonable
requests of Lessor in connection with any such transfer,  assignment,  mortgage,
grant or other  disposition  (including in connection with any such conversion),
including the execution of all consents and  amendments in connection  therewith
and the reissuance of any insurance certificates,  broker's letters and broker's
acknowledgment required in connection therewith and otherwise, the reissuance or
reproduction of the documents required under Schedule 6, in each case, with such
changes as necessary to reflect such transfer,  assignment,  mortgage,  grant or
other disposition.

                14.1.3  Absolute Transfer

                In connection  with the transfer of Lessor's  entire interest in
this Lease  Agreement  (other  than as security  and other than with  respect to
indemnities  and  third-party   liability  insurance)  as  provided  herein  (an
"Absolute Transfer"):

     14.1.3.1  Lessor's  obligations  under this Lease  Agreement  and the other
Operative  Documents  shall  be  assumed  by the  transferee  or  assignee  (and
thereupon  the assigning  Lessor shall be released  from all of its  obligations
hereunder).

     14.1.3.2  Lessor  shall  transfer  (1) any cash  constituting  the Security
Deposit or (2) the Letter of Credit to such transferee or assignee.

     14.1.3.3 (1) Lessee's  rights under the  Operative  Documents  shall not be
materially adversely affected by such Absolute Transfer and (2) Lessee shall, as
an immediate consequence of such Absolute Transfer, incur no additional material
obligations  or  additional  material  (over  $[  ]*  in  the  aggregate)  costs
(financial or otherwise) hereunder or under any other Operative Document (unless
Lessor agrees to indemnify Lessee  therefor),  provided that neither a change in
the  Person or  Persons  to whom,  or for whose  benefit,  Lessee  performs  its
obligations under the Operative Documents,  nor an increase in the number of, or
change in the nature of, beneficiaries under any  indemnification,  insurance or
other obligation shall, in each case, constitute by itself or in the aggregate a
material  increase in the  obligations of Lessee under the Operative  Documents.
Notwithstanding   any  provision  to  the  contrary,   Lessor  agrees  that  the
requirements of this Section 14.1.3.3 shall also apply to any transfer by Lessor
of any part of its interest in this Lease Agreement.

                                       47
<PAGE>

     14.1.3.4 Such  transferee or assignee  shall make for the benefit of Lessee
all of the Lessor's representations set forth herein.

     14.1.3.5  Such  transferee  or  assignee  shall be a "citizen of the United
States" as defined in 49 U.S.C.  40102(a)(15)  and shall execute and record with
the Aviation Authority all such documents and instruments as may be necessary or
appropriate in order to preserve  without  interruption  the registration of the
Aircraft.

     14.1.3.6  Such  transferee  or  assignee  shall not be the  subject  of any
bankruptcy,  reorganization or similar  proceeding and shall have a Tangible Net
Worth not less than US$[ ]*.

competitor of Lessee.

Without  prejudice to any rights of any Indemnified Party hereunder or under any
other  Operative  Document in effect on or after the  occurrence  of an Absolute
Transfer, for a period of two years after such Absolute Transfer and at Lessee's
cost, if any,  Lessee shall comply with the terms and conditions of Section 11.3
with respect to the "Lessor" and each other  "Indemnified  Party" (as determined
immediately  prior to such Absolute  Transfer) as if the effective  date of such
Absolute Transfer were the last day of the Lease Term.

                14.1.4  Transfer as Security

                Without limiting the generality of Section 14.1.2, in connection
with any transfer, assignment, mortgage, grant, novation or other disposition as
security (a "Security Transaction") by Lessor of its interests hereunder,  under
the other Operative Documents or in the Aircraft,  to any Security Agent, Lessee
shall, at Lessor's expense:

     14.1.4.1 Enter into  documentation  customary for Security  Transactions of
the type so contemplated, and shall make such filings, and take such actions, as
may be requested by Lessor in connection therewith.

     14.1.4.2  Lessee and Lessor shall amend and/or  restate this  Agreement and
any relevant Operative Document to reflect the Security  Transaction,  including
(1) an  amendment  to the  definition  of  Operative  Documents  to include  the
documents and instruments to be entered into and/or delivered in connection with
the Security  Transaction,  and, in the case where the Security  Transaction  is
consummated   on  the  Delivery  Date,  the  inclusion  of  such  documents  and
instruments  in Section 1 of Schedule 6, and (2) amendments to the insurance and
indemnity  provisions  and  definitions,  in each case,  in order to provide the
Financing Parties with customary rights and protections.

           14.2  Assignment by Lessee

           Except  as  otherwise  expressly  provided  herein,  Lessee  may not,
without the prior  written  consent of Lessor,  which consent may be withheld in
Lessor's sole discretion,  assign (by express assignment,  merger, consolidation
or otherwise) any of its rights or delegate any of its obligations  hereunder or
under any other Operative Document.

           14.3  Successors and Assigns

           Subject  to the  foregoing,  the terms and  provisions  of this Lease
Agreement and each other  Operative  Document shall be binding upon and inure to
the benefit of Lessor and Lessee and their respective  permitted  successors and
assigns.

      SECTION 15.  NO SETOFF, COUNTERCLAIM, ETC.

      This Lease Agreement is a net lease and Lessee's obligation to pay Rent is
and shall be  absolute  and  unconditional  and shall not be abated,  suspended,

Agreement  or any other  Operative  Document or in the Aircraft by Lessor or any
change of  ownership  of Lessor,  or (10) any other  circumstance,  happening or
event  whatsoever,  whether or not similar to the foregoing,  which but for this
provision  would or might  have the  effect of  terminating  or in any other way
affecting any obligation of Lessee hereunder,  it being the express intention of
Lessor and Lessee that all Rent and other amounts payable by Lessee hereunder or
under any other  Operative  Document shall be payable in all events,  unless the
obligation  to pay  the  same  shall  be  terminated  pursuant  to  the  express
provisions of this Lease Agreement.

      Lessee hereby waives,  to the extent  permitted by applicable Law, any and
all rights  which it may have or which at any time  hereafter  may be  conferred
upon Lessee, by Law or otherwise,  to terminate,  cancel, quit or surrender this
Lease Agreement or any other Operative Document,  or to abate,  suspend,  defer,
reduce or  otherwise  fail to comply in full with any  obligation  imposed  upon
Lessee hereunder or thereunder or in relation hereto, except termination of this
Lease Agreement in accordance  with the express  provisions  hereof.  If for any
reason  whatsoever  this Lease  Agreement is  terminated  in whole or in part by
operation of Law or otherwise,  except as specifically  provided herein,  Lessee
nonetheless  agrees to pay  Lessor an amount  equal to each Rent  payment at the


                                       50
<PAGE>

time such payment would have become due in accordance  with this Lease Agreement
and each other  Operative  Document had this Lease Agreement not been terminated
in whole or in part until  Return of the  Aircraft to Lessor.  Each Rent payment
made by Lessee  shall be final,  and Lessee shall not seek to recover all or any
part of any such payment for any reason whatsoever.

      Nothing in this  Section 15 shall be  construed  to limit any right Lessee
may have to  independently  pursue any claim it may have  against  Lessor or any
Indemnified Party under this Lease Agreement, applicable Law or otherwise.

      SECTION 16.  FURTHER ASSURANCES, ETC.

           16.1  Further Assurances

           Without  limiting the other  obligations  and  liabilities  of Lessee
under this Lease Agreement and the other Operative  Documents,  Lessee agrees to
promptly  and duly  execute  and deliver to Lessor such  further  documents  and
assurances  and take  such  further  action  as  Lessor  may  from  time to time
reasonably  request in order to effectively  carry out the intent and purpose of
this Lease Agreement and the other Operative Documents and to establish, perfect
and protect the rights and  remedies  created or intended to be created in favor
of Lessor and each Financing  Party  hereunder and thereunder and if applicable,
any Security Agent under any Security Transaction.

           16.2  Lessor's Performance of Lessee's Obligations

           If Lessee  fails to make any  payment  of Rent or fails to perform or
comply with any  agreement,  covenant or obligation  contained  herein or in any
other Operative Document, Lessor or Security Agent shall have the right, but not
the  obligation,  at its  election  and  without  waiver of any of its rights or
remedies against Lessee,  to perform or comply with such covenant,  agreement or
obligation  and/or  pay such  amount,  and the  amount of such  payment  and any
Expenses incurred by Lessor or Security Agent, as the case may be, in connection
with such  payment or the  performance  of or  compliance  with such  agreement,
covenant or obligation,  as the case may be,  together with interest at the Past
Due Rate,  shall be payable by Lessee to Lessor or Security  Agent,  as the case
may be, upon demand as Supplemental  Rent. The taking of any action by Lessor or
Security  Agent,  as the case may be,  pursuant to this  Section  16.2 shall not


                                       51
<PAGE>

constitute a waiver or release of any  obligation  of Lessee  hereunder or under
any other Operative  Document nor a waiver of any Default which may arise out of
Lessee's nonperformance of such obligation,  nor an election or waiver by Lessor
or  Security  Agent,  as the case may be, of any right or  remedy  available  to
Lessor  under or in  relation  to this Lease  Agreement  or any other  Operative
Document.

           16.3  No Implied Waivers; Rights Cumulative

                16.3.1 No failure  on the part of Lessor or any other  Person to
exercise and no delay in exercising any right,  power, remedy or privilege under
any  Operative  Document  or  provided  by  statute  or at Law or in  equity  or
otherwise  shall  impair,  prejudice  or  constitute a waiver of any such right,
power,  remedy or  privilege or be construed as a waiver of any Event of Default
or as an acquiescence  thereto,  nor shall any single or partial exercise of any
such right, power,  remedy or privilege impair,  prejudice or preclude any other
or further exercise thereof or the exercise of any other right, power, remedy or
privilege. No acceptance of partial payment or performance shall, whether or not
expressly  stated,  be or be deemed to be a waiver of any Event of Default  then
existing or a waiver or release of full payment and performance. No notice to or
demand on Lessee shall in any case entitle Lessee to any other or further notice
or demand in other or similar  circumstances or constitute a waiver of the right
of  Lessor  or  any  other  Person  to  any  other  or  further  action  in  any
circumstances without notice or demand.

                16.3.2 Each and every  right,  power,  remedy and  privilege  of
Lessor  and any other  Person  under  the  Operative  Documents  (1) shall be in
addition to and not in limitation of, or in  substitution  for, any other right,
power,  remedy or privilege under any Operative Document or at law or in equity,
(2) may be  exercised  from time to time or  simultaneously  and as often and in
such order as may be deemed expedient by Lessor and such Person and (3) shall be
cumulative  and not  mutually  exclusive,  and the  exercise of one shall not be
deemed a waiver of the right to exercise any other.

one  jurisdiction.  Lessee and Lessor further agree that a final judgment in any

other  Operative  Document  shall be conclusive and may be enforced in any other
jurisdiction  within or  outside  the  United  States of  America by suit on the

irrevocably  waives, to the fullest extent permitted by Law, any objection which

proceeding  arising  out of or  relating  to this Lease  Agreement  or any other
Operative  Document  brought  in any court in or of the  State of New York,  and

           Each of Lessor and Lessee irrevocably and unconditionally agrees that

invalidate  the proceeding  concerned.  Notwithstanding  the foregoing,  nothing

date and/or  total hours and cycles  since new or since the last  overhaul  and,
where applicable, indicate that such Part is new, serviceable or overhauled.

Lessee may use a replacement  part that does not comply with the requirements of
this Section  1.3.1 if a complying  part cannot be procured or installed  within
the available  ground time of the  Aircraft,  provided that the original Part is
reinstalled  or the  noncomplying  part is removed  and  replaced by a complying
part, in each case as promptly as  practicable  (and in any event within 60 days
of removal or, if earlier, on or before the last day of the Lease Term).

                1.3.2  Ownership of Parts

                Immediately  upon  any  part's  (including  Modification  Parts)
becoming  incorporated  in,  installed  on or  attached  to the  Airframe or any
Engine,  without  further  act (1) title to such part  shall  thereupon  vest in
Lessor,  free and clear of all Liens (other than Permitted Liens), (2) such part
shall  become  subject  to the  Lease  Agreement  and be deemed a "Part" of such
Airframe or such Engine for all  purposes  hereof and (3) title to any  replaced


                                       5
<PAGE>

Part shall thereupon vest in Lessee,  free and clear of all rights of Lessor and
all Lessor  Liens and shall no longer be deemed a Part  hereunder,  except  that
with respect to  non-complying  parts  described in the last sentence of Section
1.3.1 of this Schedule 2 where such non-compliance is due to the failure to meet
the  requirements of Section 1.3.1.1 or 1.3.1.2 of this Schedule 2 and the parts
described in Section  1.4.6 of this  Schedule 2, title thereto shall not vest in
Lessor.  Lessee will at its own  expense  take all such steps and  execute,  and
procure the execution of, all such instruments as Lessor may reasonably  require
and which are  necessary  to ensure that title so passes to Lessor  according to
all applicable  laws. At any time when requested by Lessor,  Lessee will provide
evidence  to Lessor's  reasonable  satisfaction  (including  the  provision,  if
required,  to Lessor of a legal opinion) that title has so passed to Lessor. All
Parts (other than  Modification  Parts) at any time removed from the Airframe or
any Engine shall remain the property of Lessor,  no matter where located,  until
such time as such Parts shall be replaced by Parts which have been  incorporated
or  installed  in or attached  to the  Airframe or any Engine and which meet the
requirements  set forth in Section 1.3.1 of this Schedule 2. Upon any removal of
Modification  Parts pursuant hereto,  title thereto shall,  without further act,
vest in Lessee free and clear of all rights of Lessor and all Lessor Liens,  and
such Modification Part shall no longer be deemed a Part hereunder.

                1.3.3  Removed Parts

                The   asset   value,   performance   standards,   manufacturer's
specifications,  modification  status,  interchangeability  status and SB and AD
incorporation  status  of all  removed  Parts  shall be  maintained  during  the
accomplishment  of all  maintenance,  modifications,  inspections,  repairs  and
overhauls.

           1.4  Modifications

                1.4.1  Ability to Modify

                Lessee,  at its own  expense,  may from time to time add further
parts or accessories and make such  Modifications  to the Airframe or any Engine
as Lessee may deem  desirable in the proper  conduct of its business (so long as
title to any Obsolete Parts shall remain in Lessor), provided that:

                      1.4.1.1  No Major Modifications

     Lessee shall not, without  Lessor's prior written  consent,  make any Major
Modifications  to the Aircraft,  and in connection  with  obtaining such consent
Lessee  shall (1) provide  Lessor with  advance  copies of all  designs,  plans,
diagrams,  drawings  and data to be used by Lessee in  accomplishing  such Major
Modifications  and (2)  obtain  the prior  approval  of the  Aviation  Authority
evidenced  by the  issuance by the Aviation  Authority  of a  supplemental  type
certificate or similar certificate.

<PAGE>

                      1.4.1.2  May Not Diminish Value, Etc.

     No such Modification shall diminish the value or utility of the Airframe or
such Engine, or impair the condition or airworthiness  thereof, below the value,
utility,   condition  or  airworthiness   thereof   immediately  prior  to  such
Modification,  assuming  the  Airframe or such Engine were then of the value and
utility and in the condition  and repair  required to be maintained by the terms
of the Lease Agreement and each other Operative Document.

                1.4.2  No Obligation of Lessor to Pay

                Except as  required  under  Section  1.2.1 of this  Schedule  2,
Lessor  shall  not be  required  under  any  circumstances  to pay  directly  or
indirectly for any Modifications.

                1.4.3  Removal of Modification Part

                Notwithstanding  the  foregoing,  Lessee may, at any time during
the Lease Term, so long as no Payment/Bankruptcy Default shall have occurred and
be  continuing,  remove or  suffer to be  removed  any such  Modification  Part,
provided  that  such  Modification  Part  (1)  is in  addition  to,  and  not in
replacement  of  or  substitution  for,  any  Part  originally  incorporated  or
installed  in or attached to the  Airframe or any Engine at the time of delivery
thereof or any Part in replacement of or substitution  for any such Part, (2) is
not  required to be  incorporated  or  installed  in or attached or added to the
Airframe or any Engine  pursuant to the terms hereof and (3) can be removed from
the Airframe or such Engine without damaging the Airframe or such Engine (unless
such  damage is  repaired  by Lessee) or  diminishing  or  impairing  the value,
utility, condition or airworthiness which the Airframe or such Engine would have
had at such time had such  Modification not been made,  assuming the Airframe or
such Engine was then of the value and utility  and in the  condition  and repair
required  to be  maintained  by the terms of the Lease  Agreement  and the other
Operative Documents.

                1.4.4  Reversal of Modification

                Except  as  otherwise  agreed by  Lessor  in  writing,  upon the
written  request of Lessor,  to be given at least 30 Business  Days prior to the
scheduled  expiration of the Lease Term, Lessee shall, on or before the last day
of the Lease Term and at its own expense,  reverse any  Modification and restore
the Aircraft to its  required  condition  as if such  Modification  had not been
made.

                1.4.5  Title to Removed Modification Part

                Upon the removal by Lessee of any Modification  Part as provided
in Sections  1.4.3 and 1.4.4 of this  Schedule 2, title thereto  shall,  without


                                       7
<PAGE>

further act, vest in Lessee free and clear of Lessor and all Lessor  Liens,  and
such  Modification  Part  shall no longer be  deemed a Part of the  Airframe  or
Engine from which it was removed. Any Modification Part not removed by Lessee as
above provided prior to the return of the Airframe or Engine to Lessor hereunder
shall remain the property of Lessor.

                1.4.6  Passenger Communication Equipment

                Notwithstanding  Sections  1.3.1.1 and 1.3.2 of this Schedule 2,
Lessee may from time to time install on the Aircraft equipment that is leased or
conditionally sold to Lessee (and title to such equipment shall remain vested in
the lessor or  conditional  vendor  thereof) if (1) such  equipment is passenger
communications  and  entertainment  equipment and (2) it can be removed  without
causing  material  damage to the Aircraft and any damage  caused by such removal
is, prior to Return, repaired so that the Aircraft is restored to a condition at
least as good as prior to such installation (ordinary wear and tear excepted).

                1.4.7  Service Bulletin Kits

                During the Lease Term, Lessee shall from  time-to-time  request,
and shall install or retain, all SB kits relating to the Aircraft, any Engine or
any Part  which are  available  to Lessee at no cost  other  than  shipping  and
handling  costs.  If any "no cost" period lapses without  Lessee  acquiring such
kit,  Lessee shall be obligated to acquire such kit at the  manufacturer's  then
cost for such kit.

           1.5  Documentation

                1.5.1 During the Lease Term, Lessee shall maintain:

Lessee is no longer required to retain under the provisions of Lessee's approved
maintenance  policies and the  requirements  of the Aviation  Authority shall be
returned to Lessor at or before the Return.

     1.5.1.3  Updates  or  additions  to  any  of the  foregoing  and  renewals,
revisions and  replacements to any of the foregoing from time to time created or

during the Lease Term.

                1.5.2 Any Aircraft  Documentation  not already  owned by Lessor,
when and as created or obtained by Lessee,  shall thereupon  become the property
of Lessor.

           1.6  Operation

                1.6.1  Lessee  shall not  operate  the  Aircraft  (or permit the
operation of the  Aircraft) in  violation  of any Law of any  Government  Entity
having  jurisdiction,  in  violation of the Approved  Maintenance  Program,  any
manufacturer's operating manuals,  recommendations or instructions, in violation
of any  airworthiness  certificate,  license  or  registration  relating  to the

Jurisdictions,  (2) on routes other than those approved by the government of the
State  of  Registration  (if the  government  of the  State of  Registration  is
approving  routes)  between  destinations  in the Permitted  Jurisdictions,  (3)
except as permitted pursuant to Section 8.5 of the Lease Agreement,  in any area
excluded  from  coverage by any  insurance in effect or required by the terms of
the Lease  Agreement or in any war zone or in any recognized or threatened  area
of  hostilities  (without  Lessor's  consent)  and unless  fully  covered to the
satisfaction of Lessor by war-risk and allied perils insurance.

                1.6.3 Lessee  shall not use,  suffer or cause the Aircraft to be
used for the  carriage  of (1) whole  animals  living or dead (other than living
humans) except in the cargo compartments  according to I.A.T.A.  regulations and

                1.6.4  Lessee  shall not use, or permit the use of, the Aircraft
for testing or for  training,  qualifying or  reconfirming  the status of flight
crew members  other than  employees  of Lessee,  and then only if the use of the
Aircraft for such purpose is not disproportionate to the use for such purpose of
other Airframe Manufacturer Model 737-300 aircraft owned or operated by Lessee.

                1.6.5  Notwithstanding  anything herein to the contrary,  Lessee
shall not install,  and shall not permit the  installation of, any Engine on any
airframe that is not an Airframe Manufacturer Model 737-300 or -500 airframe.

           1.7  Identification Plates, Etc.

           Lessee  shall  affix  and at all times  maintain  in  respect  of the
Airframe  and each  Engine and the APU a fireproof  and  legible  identification

OWNED BY BOULLIOUN  PORTFOLIO FINANCE I, INC. AND IS HELD UNDER LEASE BY WESTERN
PACIFIC AIRLINES, INC."

     1.7.2 In the  case of each  Engine,  in a  clearly  visible  place in close
proximity  to the  manufacturer's  plate,  "THIS  ENGINE  IS OWNED BY  BOULLIOUN
PORTFOLIO  FINANCE I, INC. AND IS HELD UNDER LEASE BY WESTERN PACIFIC  AIRLINES,
INC."

     1.7.3 In the case of the APU, in a clearly visible place in close proximity
to the manufacturer's  plate, "THIS APU IS OWNED BY BOULLIOUN  PORTFOLIO FINANCE
I, INC. AND IS HELD UNDER LEASE BY WESTERN PACIFIC AIRLINES, INC."

           If any  such  identification  plate  is lost or  damaged  or  becomes
illegible,  Lessee  shall  promptly  replace  it  with  a  identification  plate
complying  with  the  requirements  of this  Section  1.7.  If  Lessor  sells or
transfers its interest in the Aircraft in accordance with the Lease Agreement or
if  Lessor  notifies  Lessee  that  any  Security  Agent is a  mortgagee  of the
Aircraft,  then Lessee will promptly replace all identification  plates with new
identification  plates  which  specify the new owner and lessor of the  Aircraft
and/or  which note the  interests  of such  Security  Agent,  in any case in the
manner  specified  by  Lessor.  Lessee  shall not alter or remove or permit  the
alteration or removal of the  registration  certificate or the  nationality  and
registration marks required to be maintained on the Aircraft.
           1.8  Costs of Maintenance, Operation, Etc.

                1.8.2  Payment of Flight Charges

                Without  limiting  the  effect  of  Section  6.2.3 of the  Lease
Agreement,  Lessee shall pay promptly upon the same becoming due and payable all
Flight  Charges  incurred  by Lessee  whether in respect of the  Aircraft or any
other aircraft of Lessee,  except to the extent being contested in good faith by
appropriate  proceedings  (and for the payment of which  adequate  reserves have
been  provided) so long as such contest does not involve any material  danger of
the sale,  forfeiture  or loss of the  Airframe,  any  Engine or any Part or any
interest therein or any adverse effect on Lessor. Upon Lessor's written request,
Lessee shall  provide to Lessor a list of the airports to which Lessee  operates
the Aircraft and, if also reasonably so requested by Lessor,  any other aircraft
operated by Lessee. Upon Lessor's written request, Lessee shall authorize Lessor
(or its designee) to confirm the status of Lessee's payment of Flight Charges at
such airports or with any other Government Entity specified by Lessor.

           1.9  Inspection

                1.9.1  Maintenance Schedule

                During  the  Lease  Term,   Lessee  shall  furnish  Lessor  such
information concerning the location,  condition,  maintenance, use and operation
of the Aircraft as Lessor may  reasonably  request.  Lessee shall provide Lessor
with  maintenance  schedules  relating to the Aircraft from time to time as such
schedules  are adjusted or updated.  Lessee shall give Lessor  reasonable  prior
notice of the date of, and any change in the date of,  any Major  Checks  and/or
planned  visit to a  maintenance  facility,  in order to enable  Lessor,  or its
agents,  representatives  or designees,  to inspect the Aircraft  (including the
Aircraft  Documentation)  at Lessee's  maintenance  facility and at the time and
place any such Major Checks or visits occur.

                1.9.2  Reasonable Inspections

                      1.9.2.1  Lessor's Inspections

     At all reasonable times (including during Major Checks), Lessor's personnel
and/or its authorized representatives (including the personnel and/or authorized
representatives of a potential  Follow-On Operator) may (at Lessor's expense, or
if such  inspection is made in connection  with or following an Event of Default
which is then continuing,  at Lessee's expense) inspect the Airframe and Engines
and inspect  and make copies of the books and records of Lessee  relating to the
Airframe and Engines and the maintenance of the Airframe and Engines  (including
any  Aircraft   Documentation,   the  Approved  Maintenance  Program,  and  also
including,  for the avoidance of doubt, any airworthiness  directive and service
bulletin compliance records, component life status reports, and the then-current
aircraft  configuration),  and if such  inspection  is  made at the  time of any


                                       12
<PAGE>

maintenance operation, such Persons may inspect behind any panels, bays or other
apertures  that  have  already  been  opened in the  course of such  maintenance
operation, provided that, so long as no Event of Default shall have occurred and
be continuing, no exercise of such inspection right shall unreasonably interfere
with the normal  operation or maintenance of the Aircraft by Lessee and provided
that if Lessor  detects or observes any corrosion or other  condition  requiring
repair  under the  Approved  Maintenance  Program,  and such  corrosion or other
condition is not limited to the then-open  panels,  bays or other  components of
the  Aircraft,  Airframe  or Engine,  then  Lessor  shall be entitled to require
Lessee  to  open,  or cause  to be  opened,  such  additional  panels  as may be
necessary to identify,  correct,  repair or defer such corrosion or condition in
accordance  with the Approved  Maintenance  Program,  the Airframe  Manufacturer
Structural  Repair  Manual and the  Corrosion  Prevention  Manual.  Except  with
respect  to   inspections   occurring   after  the  occurrence  and  during  the
continuation  of an Event of Default and except during the last 12 months of the
scheduled Lease Term, in both cases, in connection with the potential transition
of the Aircraft  from Lessee,  Lessor shall not  designate  any personnel of any
competitor of Lessee as Lessor's  authorized  representative  under this Section
1.9.2.1.

                      1.9.2.2  Purchase and/or Follow-On Lease

     Without  limiting any other  provision of the Lease  Agreement or any other
Operative  Document,  upon  request  by Lessor,  Lessee  shall from time to time
during the Lease Term make the Aircraft,  including the Aircraft  Documentation,
available for inspection and/or  photocopying to designated  representatives  or
technical teams evaluating the Aircraft for purchase and/or use after the end of
the Lease Term.  Lessor agrees to give Lessee  reasonable  advance notice of any
such  inspection  and,  so  long as no  Payment/Bankruptcy  Default  shall  have
occurred and be continuing, to coordinate such inspections with Lessee so as not
to  unreasonably  interfere  with Lessee's  operation or maintenance or with its
personnel.  All such inspections and  photocopying  shall be at the sole cost of
Lessor (or if such  inspection is made in connection  with or following an Event
of Default which is then continuing, at Lessee's expense). Lessee will cooperate
with Lessor, or any prospective  purchaser or Follow-On Operator,  in permitting
and facilitating the review of the Approved Maintenance Program,  including work
cards, for the purpose of transitioning the Aircraft to a different  maintenance
program.

                1.9.3  No Duty to Inspect

                Lessor  shall  not have a duty to make any such  inspection  nor
shall it incur any  liability or obligation to Lessee by reason of making or not
making any such inspection.

           2.4  No Negative Balances

           Lessor shall not be obliged to pay any sum under Sections 2.2 of this
Schedule 2 to the extent the amount requested would exceed the lesser of (1) the
balance in the  relevant  notional  account  at and as of the time the  relevant
check,  Basic Shop Visit or Landing  Gear  Overhaul  was  completed  and (2) the
balance of such notional account at the time Lessor is required pursuant to this
Section 2 to make a payment to Lessee in respect of such request. In any case in

           For the  avoidance of doubt,  it is agreed and  acknowledged  that as
between Lessor and Lessee the amounts in the accounts referred to in Section 2.3
of this  Schedule  2 are the sole and  exclusive  property  of Lessor and Lessor
shall be  entitled  to retain  absolutely  any  credit  balance,  including  any
interest thereon,  on the accounts referred to in Section 2.3 of this Schedule 2
remaining  after any expiration or termination of the Lease Term,  except as set
forth in Section 10.2 of the Lease Agreement.

           Lessee shall submit to Lessor  detailed and  substantiated  labor and
material  invoices for all maintenance for which  reimbursement  is sought under
this Section 2 (using best  efforts so that Lessor  receives  such  invoices not
later than the 30th day  following  receipt by Lessee of such  invoices from the
Approved Maintenance  Performer (or, if such maintenance is performed by Lessee,
not later than the 30th day following  completion of such maintenance)).  Lessor
shall pay to Lessee all amounts reimbursable hereunder promptly upon its receipt
of such invoices.  In the event that any payment  otherwise due to Lessee is not
paid to Lessee as the result of any Default  then  continuing,  Lessor shall pay
such amount to Lessee promptly upon Lessee's having cured such Default, but only
if no other Default shall be then continuing.

      Section 3.  Return of the Aircraft

           3.1  Date and Location of Return

Affiliates  fully  indemnified  at all times and on an after-tax  basis from and
against all  Expenses  arising  directly or  indirectly  from any injuries to or
deaths of Lessor's representatives or loss of or damage to property of Lessor or
its   representatives   or  the  Inspecting  Parties  or  designees  during  the
inspections described in this Section 3.

           3.8  Failure to Return Aircraft

           If Lessee  shall,  for any  reason  whatsoever,  fail to  return  the
Aircraft  at the time or in the  condition  specified  herein  or  return of the
Aircraft is not accepted by Lessor (in its sole discretion)  because of Lessee's


                                       19
<PAGE>

failure to meet the  requirements  of this Section 3, the  obligations of Lessee
provided  in the Lease  Agreement  and each other  Operative  Document  to which
Lessee is a party  (including  the  obligation  to pay Rent)  shall  continue in
effect with respect to the Aircraft,  and the Lease Term shall,  unless  earlier
terminated  in  accordance  with the Lease  Agreement,  be deemed to be extended

all such Required Modifications and inspections prior to the Return. In the case
of each such Required  Modification,  Lessor shall reimburse Lessee for the cost
of such modification  pursuant to Section 2 of Schedule 3 to the Lease Agreement
as if such modification fell within the scope of such section,  provided further
that if Lessor shall be so required to reimburse Lessee,  Lessee shall, prior to
performing  such  modification,  provide  Lessor with at least 10 Business  Days
written notice of Lessee's intent to perform such  modification  together with a
detailed  cost  estimate,  and Lessor may,  within such 10 Business  Day period,
elect to have Lessee not perform such modification.

           Have neither Engine on watch for any reason whatsoever,  and (1) each
of the Engines  shall have an EGT margin of not less than  22(degree)C,  (2) the
trend  monitoring  data for each Engine  shall not exhibit any  abnormal  trends
during the six month period prior to Return,  and (3) the Engine operational and
performance  parameters shall be sufficiently  within limits specified by Engine
Manufacturer  and the condition of the Engine shall  otherwise be such to permit
full take-off power to  manufacturer's  specification.  If Lessor and Lessee are
unable to agree  whether such  criteria  have been met,  Lessor and Lessee shall
consult a qualified  Engine  Manufacturer  engineer and agree to be bound by the
determination  of such engineer (the cost of such engineer to be shared  equally
by Lessor and Lessee). Any deficiencies shall be corrected by Lessee.

                1.6.1  Engine Borescope

                With  respect to each Engine,  have had a complete  (100% of all

be  provided to Lessor  reflecting  the  correction  of any  discrepancies  from
manufacturer or regulatory  limitations,  specifications and/or tolerances found
during such inspection.

                1.6.2  Full-Rated Performance

                Be  capable  of  certificated,  full-rated  performance  without
limitations  throughout the operating envelope as defined in the airplane flight
manual;  performance  compliance  will  be  demonstrated  by  one  or two of the
following,  at Lessor's option:  (1) at the time of the acceptance  flight test,
(2) by on-wing static  inspection  and testing of the  powerplants in accordance
with the  engine  maintenance  manual,  (3) by  review of trend  monitoring  and

including  loss or  expenses  incurred  because  of  inability  to  operate  the

      (A) Taxes that are imposed on a Tax  Indemnitee by any  Government  Entity
and that are based on, or measured by, gross or net income or gross or net worth
or capital of any Tax Indemnitee (notwithstanding the foregoing, Section 1 shall
apply to, and the Tax Indemnitees shall be indemnified  against,  any such Taxes
(1) which are in the nature of sales, use, rental, ad valorem, license, property
or value-added Taxes or (2) to the extent such Taxes would not have been imposed
by such Government Entity (other than the U.S. Federal government) upon such Tax
Indemnitee  but for (x) a relation or asserted  relation of any such  Government
Entity  to  the  Aircraft  or the  transactions  contemplated  by the  Operative
Documents,  (y) the  registration  or change in  registration  or the  actual or
deemed use, operation or location by or for any Lessee Person of the Aircraft or

the Aircraft,  including,  without limitation,  Modifications,  replacements and
substitutions, and unrelated to the Aircraft);

      (B) Sales,  use or similar transfer Taxes imposed on a Tax Indemnitee upon
any voluntary or involuntary  transfer or  disposition  (other than any transfer
pursuant to any  exercise of  remedies in  connection  with an Event of Default,
pooling  arrangement,  Event of Loss or any deemed transfer caused by any Lessee
Person)  by such  Tax  Indemnitee  of any  equitable  or legal  interest  in the
Aircraft,  Airframe,  any Engine or any Part to any Person  other than Lessee or
any Affiliate of Lessee ("Lessor Transfer"); or

      (C) Taxes to the extent  incurred  with  respect  to any period  after the
later of (1)  expiration  or earlier  termination  of this Lease and (2) the (y)
return of possession of the Aircraft in accordance  with the terms of this Lease
or (z) sale or other transfer of the Aircraft hereof  following an Event of Loss
with  respect  to the  Aircraft  in  accordance  with the  terms of this  Lease;
provided,  however,  that the  exclusion  set forth in this clause (C) shall not
apply to the extent such Taxes relate to periods  prior to, or events  occurring
or matters arising prior to or in connection with, such expiration,  termination
or sale.

      (D) Taxes  imposed  solely as a result of (I) the  willful  misconduct  or
gross  negligence of a Tax Indemnitee,  (II) the breach by any Tax Indemnitee of
any of its representations,  warranties or covenants contained in this Agreement
(unless caused by any Lessee Person) or (III) Lessor Liens;

      (E) Taxes  either not yet due or being  contested in  accordance  with the

<PAGE>

and timely  reports or returns or to pay any Taxes when due,  or (y) comply with
any  certification,  information,  documentation,  reporting  or  other  similar
requirements concerning the nationality,  residence, identity or connection with
the  jurisdiction  imposing such Taxes, if such compliance is required to obtain
or establish  relief or exemption from or reduction in such Taxes and Lessor was
eligible to comply with such requirement;

      (G) Taxes imposed under Section 887 of the Code; or

      (H) Taxes to the  extent  they  exceed the amount of Taxes that would have
been  imposed if there had not been a transfer of the  Aircraft to a Person that
is not a U.S. person.

      Section 3.  No Reduction for Withholding, Etc.

      All  payments  by Lessee  under  this  Agreement  or any  other  Operative
Document, whether in respect of Rent, interest, fees or any other item, shall be
made in full without any deduction or withholding (whether in respect of setoff,
counterclaim,  duties,  Taxes,  monetary  transfer and other  charges,  wages or
otherwise  whatsoever),  unless the withholding or deduction is required by Law,
in which event Lessee shall:

      (A) forthwith pay to Lessor such additional  amount so that the net amount
received by Lessor after the deduction or withholding will equal the full amount
which would have been received by it had no such deduction or  withholding  been
made;

      (B) pay to the relevant  Government  Entity  within the period for payment
permitted by  applicable  Law the full amount of the  deduction  or  withholding
(including,  but without prejudice to the generality of the foregoing,  the full
amount of any deduction or withholding from any additional  amount paid pursuant
to this Section 3); and

      (C)  promptly  furnish  to  Lessor an  official  receipt  of the  relevant
taxation or other  authorities  involved for all amounts deducted or withheld as
aforesaid  or, if no such  receipt is issued,  a  certificate  of  deduction  or
equivalent evidence thereof.

      Section 4.  Reports

      Lessee will  provide  promptly  upon request  such  information  as may be
reasonably  requested by a Tax Indemnitee or required to enable a Tax Indemnitee
to timely and properly fulfill its tax filing  requirements  with respect to the
transactions  contemplated  by  the  Operative  Documents,   including,  without
limitation,  those requirements that relate to Taxes based on or measured by the
total time the Aircraft is located in a particular place irrespective of whether


                                       3
<PAGE>

the  Aircraft is there for  revenue,  maintenance  or storage  purposes.  If any
report,  return or  statement  is required  to be filed with  respect to any Tax
which is subject to  indemnification  under  Section 1, Lessee shall timely file
the same  (except  for any such  report,  return  or  statement  which  such Tax
Indemnitee intends to file or for income tax returns or any other return, report
or  statement  which the Tax  Indemnitee  is  required by Law to file in its own
name). Lessee shall either file such report, return or statement and send a copy
of such report,  return or statement to the Tax  Indemnitee  or, where Lessee is
not permitted to file such report, return or statement, it shall notify such Tax
Indemnitee of such  requirement  and prepare and deliver such report,  return or
statement to such Tax Indemnitee in a manner satisfactory to such Tax Indemnitee
no later than 30 days prior to the time such  report,  return or statement is to
be filed.  Lessee shall hold each Tax  Indemnitee  harmless from and against any
liabilities,  including,  without limitation,  penalties,  late payment charges,
notary charges,  additions to tax, fines and interest arising out of any failure
to  timely  file  or  inaccuracy  in  any  such  return,  statement,  report  or
information  if such failure to timely file or  inaccuracy  is  attributable  to
Lessee's failure to fulfill its obligations hereunder. Lessee shall not have any
right to examine the income tax returns of any Tax Indemnitee.  Lessee agrees to
use commercially  reasonable efforts to obtain official receipts  indicating the
payment by it of all foreign  income and  withholding  Taxes that are subject to
indemnification  under Section 1 and shall promptly  deliver to the relevant Tax
Indemnitee each such receipt obtained by Lessee.

      Section 5.  Payment

      Upon written  demand of the Tax  Indemnitee,  Lessee shall pay any Tax for
which it is liable pursuant to Section 1 in immediately available funds directly
to the appropriate Government Entity or to such Tax Indemnitee,  but in no event
shall such payment be required more than five days prior to the date such Tax is
due.  Any such  demand for  payment  from a Tax  Indemnitee  shall  specify,  in
reasonable  detail,  the  calculation of the amount of the payment and the facts
upon which the right to payment is based and shall be verified  upon the request
and at the expense of Lessee by the independent accountants for Lessor. Each Tax
Indemnitee  shall promptly  forward to Lessee any notice,  bill or advice in the
nature  of a notice  or bill  received  by it  concerning  any  Tax.  As soon as
practical  after each  payment of any Tax by Lessee  directly to any  Government
Entity, Lessee shall furnish the appropriate Tax Indemnitee with the original or
a  certified  copy of a receipt for  Lessee's  payment of such Tax or such other
evidence  of  payment  of such  Tax as is  reasonably  acceptable  to  such  Tax
Indemnitee. Lessee shall also furnish promptly upon request such data as any Tax
Indemnitee  may  require  to  enable  such Tax  Indemnitee  to  comply  with the
requirements of any taxing jurisdiction.

                                       4

      Section 6.  Contest

      If a claim is made in writing  against a Tax Indemnitee  (whether on audit
or otherwise) for any Taxes that Lessee is required to pay or indemnify  against
pursuant to Section 1, such Tax Indemnitee shall notify Lessee in writing within
30 Business  Days of the receipt of such  claim,  provided  that a failure to so
notify will not diminish or relieve Lessee of any  obligations  under Section 1,
unless such failure is willful and the failure precludes a contest. If requested
by Lessee in  accordance  with  Section 1 and in  writing  within 30 days  after
receipt by Lessee of the notice  described in the preceding  sentence,  such Tax
Indemnitee  shall  in good  faith  and  with due  diligence  contact  (including
pursuing all  administrative and judicial appeals) in the name of Tax Indemnitee
or, if permitted by law and  requested by Lessee and  reasonably  acceptable  to
such Tax Indemnitee in the name of Lessee, the validity, applicability or amount
of such Taxes in appropriate  administrative or judicial  proceedings,  provided
that (1) prior to taking  such  action  Lessee  shall have  agreed to pay to Tax
Indemnitee  promptly after written demand all  out-of-pocket  costs and expenses
that Tax  Indemnitee  may  incur  in  connection  with  contesting  such  claim,
including,  without  limitation,  all reasonable legal and accountant's fees and
disbursements  and costs of  administrative  and judicial  proceedings,  and the
amount of any interest or penalties that may be attributable to and payable as a
result of contesting such claim,  and such Tax Indemnitee  shall not be required
to continue  any contest or waive any  indemnity  claims if Lessee does not make
such payments  promptly after  receiving  notice of the amounts due, (2) if such
contest is to be  initiated  by the payment of, and the claiming of a refund for
such Taxes,  Lessee shall have advanced Tax Indemnitee  sufficient  funds (on an
interest-free  basis) to make such payment, (3) no Event of Default has occurred
and is continuing, (4) the action to be taken will not result in a material risk
of sale,  forfeiture or loss of Lessor's  title to the Aircraft  (unless  Lessee
provides  a bond or  other  security  satisfactory  to  Lessor),  (5)  prior  to
commencing any action, Lessee acknowledges its liability hereunder for the Taxes
being contested and (6) at Tax Indemnitee's request, Lessee shall provide to Tax
Indemnitee a written  opinion of  independent  tax counsel  selected by such Tax
Indemnitee  that there is a reasonable  basis for such contest.  Notwithstanding
that the  conditions  set forth in clauses (1), (2), (3), (4), (5) and (6) above
may have been  satisfied,  Tax Indemnitee,  after  consulting in good faith with
Lessee,  may elect not to pursue  any  contest  or  proceeding  pursuant  to the
preceding sentence or elect to discontinue (by settlement or otherwise) any such
contest or proceeding  commenced  pursuant to the preceding  sentence,  but such
election shall  constitute a waiver by Tax Indemnitee of any right to payment or
indemnification  pursuant to Section 1 with respect to the  adjustment  that was
the subject of such proposed contest or proceeding (and any other adjustment the


                                       5
<PAGE>

contest of which is  precluded  by such  failure to contest)  and, if Lessee has
theretofore  paid or provided Tax  Indemnitee  with funds to pay any amount with
respect to such adjustments,  Tax Indemnitee shall promptly repay such amount to
Lessee.  If Tax Indemnitee  shall obtain a refund in whatever form of all or any
part of any Taxes that Lessee shall have paid or  reimbursed  to Tax  Indemnitee
hereunder,  Tax Indemnitee  shall,  provided that no Event of Default shall have
occurred and be continuing,  pay to Lessee an amount that is equal to the sum of
the amount of such refund or credit,  plus any interest  received on such refund
attributable  to any Taxes paid by, or with funds  provided by,  Lessee prior to
receipt of such refund, reduced by any Taxes incurred by Lessor by reason of the
receipt or accrual of such refund and interest and net of any expenses described
in clause (1) of the second  sentence of Section 1 that have not been previously
reimbursed,  and  increased by any Tax benefit  realized by Tax  Indemnitee as a
result or any payment by Tax Indemnitee made pursuant to this sentence, provided
further  that,  if, at the time of such  payment an Event of Default  shall have
occurred and be continuing, Tax Indemnitee shall hold the amount of such payment
as security for the obligations of Lessee to Tax Indemnitee under the Lease, and
at such time as there shall not be continuing  any such Event of Default,  shall
pay such amount to the Lessee.  Tax Indemnitee hereby agrees that it will inform
Lessee of the time and place of, and Tax Indemnitee  will not object to Lessee's
presence at, any proceeding  conducted pursuant to this Section 6 if in its good
faith discretion it determines that such proceeding will not involve any matters
unrelated  to  Taxes  that are the  subject  of  Section  1 and that it will not
otherwise  adversely affect the Tax Indemnitee,  provided that Lessee's presence
also must be allowed by applicable law and provided  further that the conditions
set forth in clauses (1), (2), (3), (4), (5) and (6) above shall have been,  and
shall continue to be satisfied.

      Section 7.  Tax Savings
      If an  Indemnified  Party or Tax  Indemnitee  determines in its good faith
that it has actually  recognized a Tax benefit (other than a foreign tax credit)
as a result of or with  respect  to any Taxes  paid or  indemnified  against  by
Lessee under Section 1 (whether by way of deduction,  credit or otherwise), such
Indemnified  Party  or Tax  Indemnitee  shall  pay  to  Lessee,  promptly  after
recognition  of such Tax  benefit,  an amount  that,  after  subtraction  of any
further Tax savings that such Indemnified Party or Tax Indemnitee  recognizes as
a result of the  payment  thereof,  is equal to the amount of such Tax  benefit,
provided  that if any such  Tax  benefit  is  subsequently  disallowed,  lost or
reduced,  Lessee shall,  upon written notice from such Indemnified  Party or Tax
Indemnitee,  promptly  repay the amounts paid to the Lessee with respect to such
Tax benefit, provided further that the amount payable under this Section 7 to an
Indemnified  Party or Tax  Indemnitee,  as the case may be, shall not exceed the


                                       6
<PAGE>

amount of all prior  payments by Lessee to such Tax  Indemnitee  or  Indemnified
Party, as the case may be, under Section 1 hereof, or Section 9 of the Lease, as
the case may be, and any excess shall be carried forward to reduce pro tanto any
future  obligations of Lessee to such Tax Indemnitee or Indemnified  Party under
Section  1  hereof,  or  Section 9 of the  Lease,  as the case may be,  provided
further that such  Indemnified  Party or Tax  Indemnitee  shall not be obligated
under this  Section 7 to pay Lessee any  amounts  with  respect to Tax  benefits
realized  as a result of any Taxes not paid or  indemnified  against  by Lessee.
Notwithstanding  anything  to the  contrary  in  Section  1, if at the  time any
payments would  otherwise be due to Lessee  pursuant to this Section 7, an Event
of Default shall have occurred and be continuing,  such Indemnified Party or Tax
Indemnitee shall hold the amount of such payment as security for the obligations
of the Lessee to Lessor  under the Lease and at such time as there  shall not be
continuing  any  such  Event  of  Default,  shall  pay such  amount  to  Lessee.
Indemnified  Parties and Tax  Indemnitees  shall use reasonable  efforts in good
faith in filing their Tax returns and in dealing with taxing authorities to seek
and to promptly  claim any such Tax benefit or savings and to minimize the Taxes
payable or indemnifiable by Lessee hereunder.

Re:      Western Pacific Airlines Lease Agreement (MSN 28869)
         dated as of June 27, 1997 For One B737-33R Aircraft U.S.Registration
         No. N964WP Manufacturer's Serial No. 28869


As the insurance broker for Western Pacific  Airlines,  Inc. (the "Client"),  we
have been  requested  to provide you with this  letter  with  respect to certain
insurance placed by us on the Client's behalf.

In connection with this letter,  we have read Section 11 and Exhibits B and C of
the agreement (and the related  definitions) between the Client and you dated as
of June 27, 1997 ("Agreement"),  dealing with insurance requirements,  a copy of
which is attached (the "Insurance  Covenant").  We have not read or reviewed the
balance of the Agreement,  including  without  limitation any provision  thereof
which might relate to or influence  the meaning of the language in the Insurance
Covenant.

We  have  placed  the  insurance  which  is the  subject  of this  letter  after
consultation with the Client and based upon the Client's instructions, which may
not have  contemplated or reflected the Insurance  Covenant.  Terms of coverage,
including limits and deductibles are based upon  information  furnished to us by
the Client, which information we have not independently verified.

On the basis of the foregoing and subject to the other qualifications  stated in
this letter, we are pleased to confirm the following:

                                       1
<PAGE>

1.       The insurance policy(ies) listed on Exhibit A hereto (the "Policies")
         is (are) in full force and effect as of the date hereof;
         

2.       As of this date,  we have not  received any notice of  cancellation  or
         non-renewal  with  respect  to the  Policies  and are not  aware of any
         circumstances  which  would  make the  giving  of such a  notice  by an
         insurer likely;

3.       In our  view,  based  upon our  understanding  of the  language  of the
         Insurance  Covenant,  the  Policies  are  consistent  with the  minimum
         requirements of the Insurance Covenant.

4.       Based upon our experience as insurance brokers,  the coverages provided
         by  the  Policies  are  consistent  with  those  normally  provided  to
         companies similarly situated to the Client.

5.       We will endeavor to advise you of Notice of Cancellation by Insurers as
         soon as  practicable  upon  receiving  the  advice  from the  insurance
         carrier.

6.       We will  endeavor to advise you if the insured does not provide us with
         renewal instructions 14 days prior to expiration.

7.       We will  endeavor to advise you if we (MMI)  cease to be the  insured's
         appointed broker as soon as practicable.

We express no view and  assume no  liability  with  respect to the  solvency  or
future  ability to pay of any of the insurance  companies  which have issued the
Policies.

We assume no obligation to advise you of any developments regarding the Policies
subsequent to the date hereof.  This letter is given on the  condition  that you
forever waive any liability  against us based upon the placement of the Policies
and/or the statements made herein with the exception only of gross negligence or
fraud.

This letter may not be republished by you or used for any other purpose  without
our prior written consent.

Very truly yours,

      2.4. LESSEE'S  CONDITIONS TO DELIVERY.  Lessee's  obligation to accept and
lease the Aircraft from Lessor hereunder shall be subject to the satisfaction of
the following conditions:

           (a) Lessor shall have  accepted  delivery of the Aircraft from Boeing
           under the Purchase Agreement.

           (b)  The  Aircraft  shall  be  in  the  condition  and  configuration
           specified in the Purchase Agreement.

                (c) On or before the Delivery Date, Lessee shall have received:

                     (i) a certificate  signed by a duly  authorized  officer of
                Lessor,  dated  the  Delivery  Date,  to  the  effect  that  the
                representations  and warranties  contained in Section 5.1 hereof
                are true and  correct  on and as of such date as though  made on
                and as of such date; and

                     (ii) a copy of the Purchase  Agreement  Assignment  showing
                consent by Boeing thereto.


SECTION 3. TERM.

           The Term with respect to the Aircraft  shall commence on the Delivery
Date and shall expire on the tenth (10th) anniversary  thereof,  unless extended
pursuant to  paragraph 6 of Exhibit D hereto or earlier  terminated  pursuant to
Section 17.


SECTION 4. RENT.

      4.1.  BASIC RENT.  Commencing  on the Delivery Date and on the same day of
each month thereafter,  Lessee shall pay Lessor rent for the Aircraft, each such
payment in the amount  specified in Exhibit B hereto ("Basic  Rent").  The Basic
Rent  amounts  are  subject  to  adjustment  as set forth in  Exhibit  B. If the
Delivery Date has no  corresponding  numerical day in any month,  the Basic Rent
Payment  Date shall be the last  Business  Day in such  month.  As a courtesy to
Lessee, Lessor agrees to provide Lessee with an invoice in advance of each Basic
Rent  Payment  Date.  The failure to provide  such an invoice  shall not relieve
Lessee of its obligation to pay Basic Rent hereunder.

      4.2.  SUPPLEMENTAL  RENT.  Lessee shall also pay to Lessor or, at Lessor's
direction,  to  whomsoever  shall be  entitled  thereto,  subject to the proviso
contained  in  Section  18.5,  any and  all  Supplemental  Rent on the due  date


                                       7
<PAGE>

specified  in the  invoice  from  Lessor to Lessee for such  Supplemental  Rent.
Lessee shall pay to Lessor, as Supplemental Rent, interest at the Incentive Rate
on any part of any  installment  of Rent not paid on the due date  thereof.  All
computations  of interest  under this Lease to be made on the basis of a 365-day
year and actual days elapsed.

      4.3. PROHIBITION AGAINST SETOFF, COUNTERCLAIM, ETC. Lessee's obligation to
pay Rent and make  other  payments  in  accordance  with  this  Lease,  shall be
absolute and unconditional  irrespective of any contingency whatsoever including
(but not limited to) (i) any right of setoff, counterclaim,  recoupment, defence
or other right which either  party  hereto may have against the other,  (ii) any
unavailability of the Aircraft for any reason,  including, but not limited to, a
requisition thereof or any prohibition or interpretation or interference with or
other restriction  against Lessor's or Lessee's use,  operation or possession of
the Aircraft (other than in violation of a covenant of quiet enjoyment),  or the
airworthiness,  merchantability,  fitness for any purpose,  condition, design or
operation of any kind or nature of the  Aircraft,  or the  ineligibility  of the
Aircraft for any particular use or trade, or for  registration or  documentation
under the laws of any relevant  jurisdiction,  or any Event of Loss  (subject to
the  provision for cessation of Basic Rent as stated in Section 11.1) in respect
of or any damage to the  Aircraft  or any part  thereof,  (iii) any  insolvency,
bankruptcy,  reorganization,  arrangement,  readjustment  of debt,  dissolution,
liquidation  or similar  proceedings  by or against  Lessor or Lessee,  (iv) any
invalidity or  unenforceability or lack of due authorization of, or other defect
in, this Lease,  and (v) any other cause which but for this  provision  would or
might have the effect of  termination  or in any way affecting any obligation of
Lessee hereunder.

      4.4.  SECURITY  DEPOSIT.  On or before the Delivery Date Lessor shall have
received  an  irrevocable  standby  letter of  credit  from a bank and in a form
acceptable  to Lessor  in the face  amount of $[ ]* (the  "Letter  of  Credit").
Promptly upon receipt of the Letter of Credit,  Lessor shall refund to Lessee $[
]*  previously  paid to  Lessor.  The  Letter  of Credit  shall  remain in place
throughout the Term, except as specified in this Section 4.4.

           The Security  Deposit shall be held by the Lessor as security for the
timely and faithful  performance  by Lessee of Lessee's  obligations  under this
Lease, and Lessee hereby grants Lessor a security interest in all sums deposited
with or  otherwise  held by Lessor  under this  Section  4.4.  Lessee  agrees to
execute  and  file  with  the  appropriate  governmental  entities  any  and all
documents  necessary or  reasonably  requested by Lessor to evidence and perfect
such security  assignment in favor of Lessor.  If an Event of Default shall have
occurred and is  continuing,  in addition to all other rights  Lessor shall have
under the New York Uniform  Commercial Code as a secured party,  Lessor may, but
shall not be  obligated  to,  draw on the Letter of Credit  and/or  use,  apply,
set-off or retain all or any  portion of the  Security  Deposit,  in payment for
sums due by Lessee, to compensate Lessor for any sums advanced as a result of an
Event of  Default  by Lessee or to apply  toward any  expenses  Lessor  actually
incurs as a result of such Event of  Default.  If Lessor  uses or applies all or
any portion of such Security Deposit as provided above,  such application  shall
not be deemed a cure of any Events of Default,  and Lessee shall within five (5)
days  deposit with Lessor in cash an amount  sufficient  to restore the Security
Deposit to the aggregate  amount of such Security  Deposit prior to Lessor's use
or application and Lessee's doing so shall be deemed a cure of any such Event of
Default  but the  failure of Lessee to do so shall be a material  breach of this
Lease by Lessee.  Provided  that an Event of Default shall not have occurred and
then be  continuing  (and in such case, at such time as no such Event of Default
shall then be  continuing)  and provided that Lessee shall have paid all amounts


                                       8
<PAGE>

owing  hereunder,  the Security  Deposit  together with accrued interest thereon
shall be  returned to Lessee at the end of the Term and  Lessee's  return of the
Aircraft in compliance with Article 13 hereof.

           Provided no Event of Default has occurred or is continuing,  promptly
following the third anniversary of the Delivery Date Lessor agrees to review the
Lessee's  financial  condition  and will confer with Lessee to determine if said
financial condition merits a reduction in the amount of the Security Deposit.

      4.5.  MANNER  AND  PLACE OF  PAYMENT.  All  amounts  to be paid by  Lessee
hereunder shall be paid by wire transfer of same day funds, consisting of lawful
currency of the United States of America,  to the account of Lessor at The First
National Bank of Chicago,  ABA No. 071000013,  Chicago,  IL 60670 account no. 52
47209, account name: GATX Capital Corporation, or to such other party or account
as Lessor shall designate in writing.  If any such amount is due to be paid on a
day  other  than a  Business  Day,  such  amount  shall be  payable  on the next
succeeding  Business  Day.  Any payment of Rent not  received  in Lessor's  bank
account by 11:00 a.m. on the due date shall be treated as having  been  received
on the next succeeding Business Day.

           and the Certificate of Acceptance,  and the other agreements executed
           pursuant  hereto  and  thereto;  and  the  execution,   delivery  and

           regulation   or  order   binding   on  Lessor,   or  any   applicable
           interpretation or administration of any such law,  governmental rule,
           regulation or order, or contravene the certificate of  incorporation,
           Bylaws  or  other  organic  documents  of  Lessor  or any  indenture,

           is a party  or by  which  it or any of its  assets  may be  bound  or

                                       10
<PAGE>

                a.   CORPORATE   EXISTENCE  AND   QUALIFICATION.   Lessee  is  a
           corporation duly  incorporated and validly existing under the laws of
           the State of Delaware and is an air carrier of persons and  property,
           registered,  licensed or otherwise  certificated  or duly  authorized
           under Part 121 of the Federal Aviation  Regulations to engage in such
           air transportation  and is duly qualified or otherwise  authorized to
           do business as an air  carrier in all  jurisdictions  in which it has
           air routes,  except for jurisdictions  where failure to so qualify or
           obtain  authorization would not have a material adverse effect on the
           business  of Lessee  and would not  involve  any  danger of the sale,
           forfeiture  or loss of any item of  Equipment  or  impairment  of the
           value thereof.

                b.  AUTHORITY.  Lessee has full corporate power and authority to
           enter into and perform this Lease and the other Lease Documents;  and
           the execution,  delivery and  performance of this Lease and the other

           bound or affected.

                c. GOVERNMENTAL APPROVALS. Neither the making nor performance by
           Lessee of this Lease or any other  document  to be executed by Lessee
           pursuant  hereto,  nor the consummation of any of the transactions by
           Lessee   contemplated   hereby  or  thereby,   nor  the  acquisition,
           Lessorship or leasing by Lessor of the Aircraft under such documents,
           requires  the  consent or  approval  of, the giving of notice to, the

           including  any  governmental  or  political  agency,  subdivision  or
           instrumentality  thereof,  except for a certificate of  airworthiness
           and a certificate of registration with respect to the Aircraft issued
           by the FAA naming Lessor as the owner of the Aircraft.

                d. BINDING OBLIGATIONS. This Lease and each other Lease Document
           executed by Lessee  constitutes  or, when executed and delivered will
           constitute,  the  valid and  legally  binding  obligations  of Lessee
           enforceable against Lessee in accordance with the terms thereof.

                e.  LITIGATION.  Except  as  otherwise  disclosed  to  Lessor in
           writing prior to the execution and delivery of this Lease,  there are
           no suits or proceedings pending in any court of before any regulatory
           commission,  board or other  administrative or governmental agency in
           the United  States  against or  affecting  Lessee which relate to the
           transactions  contemplated hereby or which, if adversely  determined,
           would  have a  material  adverse  effect on the  ability of Lessee to
           fulfill its obligations hereunder.

                                       11
<PAGE>

                f. FINANCIAL  CONDITION.  The audited balance sheet of Lessee as
           at December  31,  1996 (the "1996  Balance  Sheet"),  and the audited
           statements of profit and loss of Lessee for 1996,  each  certified by
           the independent  auditor of Lessee,  heretofore  furnished to Lessor,
           are complete and correct and have been  prepared in  accordance  with
           generally accepted  accounting  principles.  Lessee has no contingent
           obligations  (to its  knowledge),  liabilities  for taxes or  unusual
           forward or long-term  commitments which could have a material adverse
           effect on its  financial  condition,  except as disclosed in the 1996
           Balance Sheet or the notes thereto.

                g. REGISTRATION, FILING, ETC. The agent in the State of New York
           upon whom  service of process may be made on behalf of Lessee,  is CT
           Corporation  System.  Lessee will give written  notice in  accordance
           with  Section  18.2  hereof  prior to any change of address  for such
           agent.  Lessee  agrees to  maintain an agent in the State of New York
           throughout the term who is authorized to accept service of process on
           behalf of Lessee. In the event Lessee fails to maintain such an agent
           in the State of New York,  Lessee  agrees that service by mail to the
           location specified in Section 18.2 hereof shall be sufficient for all
           purposes.

                h. USE OF AIRCRAFT.  The Aircraft will be used  exclusively  for
           the carriage of persons,  property, cargo and mail as permitted under
           the laws of the United States.

                i. PARI PASSU  RANKING.  The  obligations  of Lessee to pay Rent
           hereunder  will be direct and  unconditional  general  obligations of
           Lessee,  and will rank in right of  payment  at least PARI PASSU with
           all  Debt,  whether  now or  hereafter  outstanding.  The PARI  passu
           ranking  referred to in the preceding  sentence  refers to ranking in
           right of payment only,  and does not address the issues of collateral
           security  for any Debt or recourse in respect of any Debt against any
           direct or indirect guarantor thereof.

                j. NO  CONFLICTING  AGREEMENTS.  Lessee  is not a  party  to any
           agreement or instrument or subject to any charter or other  corporate
           restriction  which  individually  or in  the  aggregate  is,  in  the
           reasonable judgment of Lessee, likely to adversely affect its ability
           to perform its obligations under this Lease.

                k. NO DEFAULT. No Default has occurred and is continuing.

                l. REPETITION.  The representations and warranties  contained in
           this  Section 5.2 (other than Section  5.2(f))  shall be deemed to be
           repeated in full upon each Basic Rent Payment  Date having  regard to
           the facts and circumstances then existing.

      5.3.  COVENANTS  OF  LESSEE.  Until  payment  in  full  of  all  Rent  and
performance  by Lessee of all its other  obligations  hereunder,  Lessee  agrees
that:

           a.   FINANCIAL STATEMENTS, REPORTS, ETC.  Lessee will furnish to
Lessor:

                                       12

                     i. as soon as  available  and in any  event  within 60 days

                of each fiscal  year of Lessee,  the  audited  balance  sheet of
                Lessee  as at the end of such  quarter  or  fiscal  year and the
                related statements of earnings for such fiscal year, prepared in
                accordance with generally accepted accounting  principles and on
                a basis  consistent  with  that used in the  preparation  of the
                financial  statements  referred to in Section 5.2(f),  except as
                noted  in  such  balance  sheet  and  statements,  certified  by
                Lessee's  independent  public  accountants  and including  their
                certificate and accompanying comment;

                     ii. promptly after Lessee shall have obtained  knowledge of
                the occurrence of any Default,  a written notice  specifying the
                nature and period of  existence  thereof and what action  Lessee
                has taken or is taking or proposes to take with respect thereto;

                     iii. not later than 30 days after entering into or becoming
                bound or  affected by any pooling or  interchange  agreement  or
                arrangement  permitted by Section 6.1 by which any Engine may be
                affected and promptly  after each amendment or  modification  of
                any such  agreement  or  arrangement,  Lessee at its option will
                either  deliver to Lessor a certified  copy of the  agreement in
                English,  or will deliver to Lessor a certificate  duly executed
                by an  authorized  officer  of  Lessee  to the  effect  that the
                pooling or  interchange  agreement is (or remains) in compliance
                with the terms of this Lease;

                     iv. prompt  written notice of any damage to any Item if the
                estimated  cost of repair  exceeds $[ ]* (or the  equivalent  in
                local currency); and

                     v. from time to time such other  information  regarding the
                Aircraft as Lessor may  reasonably  request,  including  reports
                from  time to time as to  maintenance  of the  Aircraft  and the
                Engines  (including  total  Flight  Hours  and  Cycles  and time
                between overhauls).

                b.  RECORDING.  Subject to the  requirements  of Section  5.4(a)
           below,  Lessee  will be  responsible  for and  bear  the  expense  of
           registering  the Aircraft in the United States in the name of Lessor,
           as owner and lessor,  and of recording and  rerecording,  registering
           and  reregistering and filing and refiling this Lease, each and every
           supplement to this Lease, the Mortgage(s), and such other instruments
           as are  necessary  or  reasonably  requested by Lessor to protect the
           right,  title and interest of Lessor and Mortgagee and to perfect and
           maintain the interests of Lessor and Mortgagee  created hereunder and
           under  the  Mortgage,   provided,   however,   Lessee  shall  not  be
           responsible  for  filings  with  respect to any  mortgage or security
           interest  granted by Lessor on the Aircraft or the Lease,  but Lessee
           shall  cooperate  with  Lessor's  reasonable  requests  in making and
           maintaining any such filings.

           c.   CORPORATE EXISTENCE, MERGERS, ETC.

                          i.  Lessee  will do or  cause  to be done  all  things
                necessary  to  preserve  and keep in full  force and  effect its
                status as a duly  certificated  air carrier  pursuant to (or, in
                the  event   such  law  or   regulation   is   superseded,   its
                authorization  under) FAR Part 121 to be an air carrier  engaged
                in the  carriage of persons and  property  for  compensation  or
                hire.

                          ii.  Lessee  will,  except  as  permitted  by the next
                sentence, at all times maintain its corporate existence.  Lessee
                will not  consolidate  with or merge into any other  Person,  or
                sell, lease, exchange, transfer or otherwise dispose (whether in
                one transaction or in a series of related  transactions)  of all
                or substantially all its property,  assets or revenues,  whether
                now owned or  hereafter  acquired,  unless (i) Lessee shall have
                obtained the prior written consent of Lessor, which shall not be
                unreasonably withheld or delayed, (ii) the entity formed by such
                consolidation  or  merger  or the  person  or  entity  which  so
                acquires such assets by purchase,  lease,  exchange or transfer,
                shall be a corporation duly organized and validly existing under
                the  laws  of one of  the  United  States  of  America  and is a
                certificated  air carrier and shall have  executed and delivered
                to Lessor an agreement in form satisfactory to Lessor containing
                an assumption  by such  successor of the  obligations  of Lessee
                under  this  Lease,  (iii)  no Event of  Default  exists  and is
                continuing   and   immediately   after  giving  effect  to  such
                consolidation,  merger or  acquisition,  no  Default  shall have
                occurred and be continuing  and (iv) the financial  condition of
                the surviving  entity shall not be any worse than that of Lessee
                immediately prior to such consolidation, merger or acquisition.

      5.4. COVENANTS OF LESSOR.

                a.  REGISTRATION.  Lessor  will  take  such  action  as  may  be
           requested  by Lessee,  at the expense of Lessee,  in order to file or
           record  the  Lease,  the  Certificate  of  Acceptance  and such other
           documents as may be necessary  and to register the Aircraft  with the
           FAA and  Lessee  hereby  consents  to such  filing,  recordation  and
           registration by Lessee.

                b. QUIET  ENJOYMENT.  So long as no Event of Default  shall have
           occurred  and  be   continuing,   Lessor   agrees  that,   except  as
           specifically  permitted  by the  terms of this  Lease,  it will  not,
           through  its own  actions  or  through  the  actions  of others  duly
           claiming  through or under Lessor,  interfere with Lessee's  peaceful
           and quiet use, operation and possession of the Aircraft.


SECTION 6. POSSESSION AND USE.

      6.1. POSSESSION.

           a. SUBLEASE:  ASSIGNMENT AND TRANSFER. Lessee will not assign, pledge
           or otherwise  encumber  this Lease or,  except as provided in Section


                                       14
<PAGE>

           6.1(b) below, sublet or transfer possession of the Aircraft, Airframe
           or any  Engine or  install  any  Engine or  permit  any  Engine to be
           installed on any airframe  other than the  Airframe,  provided that a
           "wet" lease of the Aircraft,  pursuant to which Lessee's flight crews
           remain in sole command of the Aircraft and its  operations,  will not
           be deemed to be a sublease of the  Aircraft,  and  provided  further,
           that so long as no Default or Event of  Default  shall have  occurred
           and be  continuing  and as long as the  action to be taken  shall not
           affect the  registration of the Aircraft and so long as all necessary
           approvals of each  Governmental  Entity having  jurisdiction over the
           Aircraft have been obtained,  then Lessee,  without the prior written
           consent of Lessor,  but in all cases  with  prior  written  notice to
           Lessor, may:

                (i)  subject  any  Engine  to  normal   interchange  or  pooling
                agreements or similar arrangements in each case customary in the
                commercial  airline  industry  and entered  into in the ordinary
                course of its business with an air carrier approved by Lessor or
                an  FAA-licensed  engine overhaul  agency;  provided that (A) no
                such  agreement  or  arrangement  results  in  or  requires  the
                transfer of title to such Engine;  and (B) if Lessor's  title to
                such  Engine  shall be  divested  under  any such  agreement  or
                arrangement,  such divestiture shall be deemed to be an Event of
                Loss with  respect to such Engine and Lessee  shall  comply with
                Section 11.2 hereof in respect thereof;

                (ii) deliver  possession  of the  Aircraft,  the Airframe or any
                Engine to the Manufacturer  thereof for testing or other similar
                purposes or to any  FAA-licensed  repair  station  for  service,
                repair,  maintenance,  testing or overhaul work on the Aircraft,
                Airframe  or Engine or any Part  thereof or for  alterations  or
                modifications  in or  additions  to the  Aircraft,  Airframe  or
                Engine  to the  extent  required  or  permitted  by the terms of
                Section 9 hereof;

                (iii) install an Engine on an airframe (other than the Airframe)
                owned  by  Lessee  free  and  clear  of all  Liens  except:  (A)
                Permitted Liens and those which apply only to the engines (other
                than Engines),  appliances,  parts, instruments,  appurtenances,
                accessories,  furnishings and other equipment (other than Parts)
                installed  on  such  airframe  (but  not to the  airframe  as an
                entirety);  and (B) the rights of the participants  under normal
                interchange  agreements  which  are  customary  in  the  airline
                industry and do not  contemplate,  permit,  result in or require
                the  transfer  of  title  to  the  airframe,  engines  or  parts
                installed thereon; and

                (iv) install an Engine on an airframe  leased to Lessee or owned
                by  Lessee  subject  to a  conditional  sale or  other  security
                agreement; provided, that (x) such airframe is free and clear of
                all  Liens  except  the  rights of the  parties  to the lease or
                conditional  sale or  other  security  agreement  covering  such
                airframe  and  except  Permitted  Liens,  and  the  lien  of any
                mortgage  which either by its terms does not apply to the Engine
                or which effectively  provides that each Engine leased to Lessee
                hereby  shall not become  subject to the lien  thereof or to any
                rights of any party  thereunder  other than Lessee (with respect
                to Lessee's rights expressly granted hereunder), notwithstanding
                the  installation of such Engine on any airframe  subject to the


                                       15
<PAGE>

                lien of such mortgage,  unless and until Lessee shall become the
                owner of such Engine and Lessor  shall have no further  interest
                therein,  all pursuant to the express  terms of this Lease;  and
                (y) there shall be in effect a written  agreement  of the lessor
                or  secured  party of such  airframe  (which may be the lease or
                conditional  sale or  other  security  agreement  covering  such
                airframe)  substantially  similar in effect to the  agreement of
                Lessor in Section  6(b)  below  whereby  such  lessor or secured
                party  effectively and expressly  agrees that neither it nor its
                successors or assigns will acquire or claim any right,  title or
                interest in any Engine by reason of such Engine being  installed
                on such  airframe  at any time  while  such  Engine  is owned by
                Lessor  and  is  subject  to  this  Lease,  and a copy  of  such
                agreement shall be provided to Lessor upon written request.

           b. PERMITTED SUBLEASE.  So long as no Default or Event of Default has
           occurred and is  continuing,  and provided that Lessee is and remains
           an air  carrier  and not an  aircraft  leasing  company,  Lessee  may
           sublease  the  Aircraft  to an  Eligible  Sublessee,  for  use on the
           Eligible  Sublessee's  regularly  scheduled  route or in its  charter
           services,  subject to the  provisions  of Section  6(c) below and the
           following additional terms and conditions:

                (1) no such  sublease  shall be scheduled to extend  beyond that
                date which is one month short of the end of the Term;

                (2) no such sublease shall be to foreign air carrier until after
                the seventh anniversary of the Delivery Date; and

                (3) no sublease shall have a term of longer than three years.

           c. CERTAIN LIMITATIONS ON TRANSFERS AND SUBLEASE. With respect to any
           transfer of possession pursuant to this Section 6.1:

                (i) the rights of any  transferee  that  receives  possession by
                reason of a  transfer  permitted  by this  Section  6.1 shall be
                subject and  subordinate to all the terms of this Lease and such
                transferee shall recognize in writing such subordination;

                (ii) Lessee  shall remain  primarily  liable  hereunder  for the
                performance of all of the terms of this Lease to the same extent
                as if such transfer had not occurred; and

                (iii)  no  interchange  agreement  or  other  relinquishment  of
                possession  pursuant  to the terms of this  Section 6.1 shall in
                any way  discharge  or diminish any of Lessee's  obligations  to
                Lessor hereunder.

      6.2.  RECIPROCAL  RECOGNITION  OF RIGHTS.  In the event  Lessee shall have
received  from the lessor or secured  party of any airframe  leased to Lessee or
owned by Lessee  subject to a  conditional  sale or other  security  agreement a
written agreement  complying with clause (y) of Section  6.1(a)(iv)  hereof, and
such lease,  conditional sale or other security agreement covering such airframe
also covers an engine or 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, Lessor hereby agrees for the benefit of such lessor
or secured  party that Lessor will not acquire or claim,  as against such lessor
or secured party, any right,  title or interest in 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 conditional sale or other security  agreement and owned


                                       16
<PAGE>

by such lessor or subject to a security interest in favor of such secured party.
Lessor also hereby  agrees for the benefit of the  mortgagee  under any mortgage
complying with clause (x) of Section 6.1(a)(iv) hereof, relating to installation
of an  Engine  on an  airframe  owned  by  Lessee,  subject  to the lien of such
mortgage, that Lessor will not acquire or claim, as against such mortgagee,  any
right,  title or interest in any engine  subject to the lien of such mortgage as
the result of such engine being installed on the Airframe at any time while such
engine is subject to the lien of such mortgage.

      6.3. NET LEASE.  Lessee shall pay for and provide all electric power, oil,
fuel and  lubricant  consumed by and required for the operation of the Aircraft.
Lessee shall  promptly  pay all  navigation  charges  (including  landing  fees,
departure fees and airport taxes) the nonpayment of which could result in a Lien
upon the Aircraft.

      6.4.  OPERATIONAL  EXPENSES;  LAWFUL INSURED  OPERATIONS.  Lessee will not
cause or permit any item of  Equipment  to be  maintained,  used or  operated in
violation  of any  law,  treaty,  statute,  rule,  regulation  or  order  of any
government or  governmental  authority  having  jurisdiction  or contrary to any
manufacturer's  operating  manuals  and  instructions,  or,  in the  case of the
Aircraft and the  Engines,  in violation  of any  airworthiness  certificate  or
registration  relating  thereto.  Lessee  agrees  not to  operate  any  item  of
Equipment, or suffer such item of Equipment to be operated, (a) unless such item
of Equipment is covered by insurance as required by the provisions of Section 12
hereof, or (b) contrary to the terms of the insurance required by the provisions
of Section 12 hereof. If the Aircraft is brought into any location or country in
which the  insurance  required by Section  12.2 is not in full force and effect,
Lessee,  in addition to its liability  under Sections 17 and 18, shall be liable
to Lessor for loss or damage to the Aircraft up to the Insured Value.

      6.5. NOTICE OF  MAINTENANCE.  Regardless of the identity of the Authorized
Maintenance  Performer,  Lessee shall notify Lessor, not less than 30 days prior
to the scheduled  commencement  thereof, of each upcoming structural  inspection
(complete or partial),  or other major check to be performed on the Airframe and
of any Engine  overhaul.  Lessee  agrees that the  Aircraft  shall be treated on
maintenance matters in the same manner as other 737-300 aircraft in the fleet of
Lessee and shall not be discriminated against in any way.

      6.6. MAINTENANCE.  Lessee, at its own cost and expense, shall:

           a. service, repair, maintain, overhaul and test, or cause the same to
           be done to, each Item leased hereunder (i) so as to keep such Item in
           the same  condition as when delivered to Lessee  hereunder,  ordinary
           wear and tear excepted,  and in good operating condition,  (ii) so as
           to keep each  Aircraft  in the  condition  necessary  to  enable  the
           airworthiness  certification of such Aircraft for operation under FAR
           Part 121 to be  maintained  in good  standing  at all times under all
           applicable  laws and  regulations  of the FAA,  and  (iii) in  strict
           compliance  with  the  Maintenance  Program.  All  revisions  to  the
           Maintenance  Program shall be delivered by Lessee to Lessor  promptly
           after the issuance of such revisions.

           b. maintain all records, logs and other materials required by the FAA
           in respect of the Aircraft;

                                       17
<PAGE>

           c. timely  furnish to Lessor such  information as may be requested by
           Lessor to enable  Lessor to file any reports  required to be filed by
           Lessor with any governmental authority concerning the Aircraft;

           d.  incorporate  into the Aircraft all  mandatory  Service  Bulletins
           issued by Boeing, CFMI or other vendors during the Lease Term and all
           recommended Service Bulletins issued by Boeing, CFMI or other vendors
           that  Lessee  adopts  during  the Lease  Term for at least 50% of the
           owned or leased Boeing 737-300  aircraft in Lessee's  fleet, it being
           the  intent  of  the  parties  that  this   Aircraft   shall  not  be
           discriminated  against  in  Service  Bulletin  compliance  and  other
           maintenance matters;

           e. carry out, on the Aircraft,  each  applicable AD which the FAA may
           from time to time  issue and which may  become  due  during the Lease
           Term;

           f. maintain during the Term all records and documents required by the
           FAA or the Maintenance Program;

           g.   maintain, service, repair and overhaul the Airframe and all
           Engines to comply with all warranty requirements pursuant to the
           Purchase Agreement;

           h. equip each  Airframe at all times with two Engines  (except as may
           be required for maintenance); and

           i. cause all  maintenance  and repairs to the  Aircraft to be done by
           Lessee or an FAA-certificated overhaul and repair station approved in
           writing by Lessor (the "Authorized Maintenance Provider").

      6.7.  INSIGNIA AND NOTICES.  Lessee will affix and maintain in the cockpit
of the  Aircraft  adjacent  to  and  in an  equally  prominent  position  as the
airworthiness certificate therein and on each Engine a nameplate satisfactory to
Lessor bearing the inscription "This [Aircraft]  [Engine] is owned by GATX Third
Aircraft Corporation and leased to Western Pacific Airlines, Inc. and is subject
to a Mortgage in favor of [Mortgagee]" or such other  inscription as Lessor from
time to time  may  reasonably  request  in order  to show  its  interest  in the
Aircraft  or to show the  interests  of third  parties  holding  a  mortgage  or
security interest in the Aircraft. Except as otherwise provided, Lessee will not
allow the name of any  Person to be placed on the  Airframe  or any  Engine as a
designation  that might be  interpreted  as a claim of  Lessorship  except  that
Lessee may place its  customary  colors and  insignia  on the  Airframe  and any
Engine.

      6.8. USE OF AIRCRAFT.  Lessee shall use the Aircraft  solely in commercial
operations for which Lessee is duly authorized.  Lessee shall not use, or permit
the use of, any  Aircraft for any purpose for which it is not  suitable.  Lessee
shall  comply  with all  regulations  of the FAA.  Lessee  shall not  permit any
Aircraft  or any Engine to be under the control of any citizen or company of any
of the following  countries:  Cuba, Haiti, Iran, Iraq, Libya, North Korea or any
of the  countries  formerly  comprising  Yugoslavia,  or any country  subject to
technology transfer  restrictions imposed by the government of the United States
of  America.  The  foregoing  sentence  shall not  prohibit  overflight  of such
countries,  nor shall the foregoing  sentence impose any greater  restriction on
the operation of the Aircraft  than is mandated by the  government of the United
States of America.

      6.9  MAINTENANCE RESERVES

           a. PAYMENT. As soon as possible, but in no event later than the tenth
           day of each month,  Lessee  shall  provide  Lessor with the number of
           Flight Hours and Cycles accumulated on the Airframe, each Engine, the
           Landing  Gear and the APU and the number of  take-offs at each of B-1
           and B-2 thrust  levels in the prior month.  On or before the 15th day
           of each month  throughout the Term, and with one final payment on the
           last day of the Term,  Lessee shall pay Lessor as  Supplemental  Rent
           the  following  amounts (the "Reserve  Rates"):  (i) $[ ]* per Flight
           Hour  accumulated on the Airframe in the preceding  month for the C-7
           Check (the "C-7 Reserve"); (ii) $[ ]* per Flight Hour on the Airframe
           in the preceding month for Landing Gear replacement and overhaul (the
           "Landing  Gear   Reserve");   (iii)  $[  ]*  for  each  running  hour
           accumulated  on  the  APU  during  the  preceding   month  (the  "APU
           Reserve");  (iv) $[ ]* per Flight  Hour  accumulated  on each  Engine
           during the preceding  month for shop visits on the Engine  modules as
           specified below (each an "Engine  Reserve");  and, (v) $[ ]* for each
           Cycle  accumulated  on each  Engine  during the  preceding  month for
           replacement  of Life Limited Parts  ("LLPs") in each Engine (the "LLP
           Reserve").

           The LLP Reserve  shall be allocated  among the LLPs in  proportion to
           their catalog prices. Each Engine Reserve will be allocated among the
           Engine modules as follows:

                               $ AMOUNTS            PERCENTAGE COST
           MODULE              PER FLIGHT HOUR         DISTRIBUTION

           Fan and Booster      $[   ]*                  [   ]*
           HPT                   [   ]*                  [   ]*
           HPC                   [   ]*                  [   ]*
           LPT                   [   ]*                  [   ]*
           Gearbox               [   ]*                  [   ]*
           Combuster             [   ]*                  [   ]*
                          -------------------------------------
                                $[   ]*                  [   ]*

           The amount of the Reserve Rates shall be adjusted annually commencing
           on the first  anniversary  of the Delivery  Date by the increase from
           January 1, 1997,  which results from applying the escalation  formula
           contained in Lessee's airframe maintenance and overhaul contract with
           BF Goodrich (Tramco) (or if such contract,  or the escalation formula
           therein,  no  longer  exists,  then the  Boeing  airframe  escalation
           formula) to all of the Maintenance Reserves except the APU and Engine
           Reserve  Rates,  which shall be adjusted  based on the CFM escalation
           formula.  Additional  increases or decreases in the Reserve Rates may
           be made on the first  anniversary  of the Delivery  Date and annually
           thereafter  based upon Lessee's  usage  pattern,  actual  maintenance
           costs and the number of Flight Hours and Cycles actually  accumulated
           on the Airframe and Engines in the prior year and anticipated for the
           coming  year,  as well as changes  in the  Maintenance  Program.  The
           payments  have  been  calculated  on the  assumptions  that  Lessee's
           utilization  will  average [ ]* Flight  Hours per Cycle and that each
           Engine will  operate at B-1 power for [ ]*% of all  take-offs  and at
           B-2 power for [ ]*% of all take-offs.

                1.  AVAILABILITY  OF RESERVES.  Each  Maintenance  Reserve shall
           remain under the sole control and direction of Lessor, subject to the
           provisions  of this  Section  6.9, and shall be available to be drawn
           upon,  following receipt of an invoice from Lessee (giving details of
           the payee and  accompanied by such  supporting  information as Lessor
           shall require), to pay for:

                     a)    the C-7 Check on the Airframe up to the amount
                available in the C-7 Reserve on the date such Check is
                completed;

                     a)    overhauls and shop visits of the APU, up to the
                amount then available in the APU Reserve on the date the work
                on the APU is completed;
                     b) Engine shop visits,  up to the amount then  available in
                the Engine Reserve  applicable to such Engine module on the date
                the work on such Engine is completed;

                     a)  replacement  of LLPs up to the amount  available in the
                LLP  Reserve  applicable  to the LLP being  replaced on the date
                such LLP is removed from the Engine; and

                     a)  overhauls  of  the  landing  gear,  up  to  the  amount
                available  in the Landing  Gear  Reserve on the date the work on
                the landing gear is completed.

           c.  PAYMENTS.  All payments from the  Maintenance  Reserves  shall be
           reduced by the  actual  amounts  received  by Lessee or due to Lessee
           under  any  applicable  manufacturer's  warranties,   guarantees  and
           concessionary  adjustments.  If, on any occasion,  the balance of any
           funds held in the particular  Reserve account is insufficient to meet
           a claim for  reimbursement in respect of such Reserve,  the shortfall
           will be  Lessee's  responsibility  and may not be carried  forward or
           made the subject of any further claim for reimbursement.

           Each invoice shall be  accompanied  by  substantiating  data from the
           Authorized Maintenance Performer. No reimbursement shall be made from
           any Reserve for any repair,  overhaul  or  inspection  occasioned  by
           Foreign  Object  Damage  (FOD),  ADs,  SBs,  faulty   maintenance  or
           installation, improper operation, misuse, neglect, ingestion or other
           accidental  cause, or repair  reimbursable  from insurance (for which
           purpose  the  deductible,  if any,  shall  be  treated  as  insurance
           proceeds) or Manufacturer's warranty, guarantee or adjustment.

           Lessor shall have no duty to determine  whether any item of Equipment
           requires  overhaul  or  maintenance,  or to observe  or  inspect  the
           overhaul or  maintenance  of any Item, and Lessor shall not incur any
           liability or  obligation  by reason of the failure of the Aircraft to
           be  properly  overhauled  or  maintained  or by  reason  of  Lessor's
           election  to observe  or  inspect  or not to  observe or inspect  any
           overhaul or maintenance.

           d. REMAINING BALANCE. At the end of the Term, the balance, if any, in
           the Maintenance Reserves shall be retained by Lessor. If the Aircraft


                                       20
<PAGE>

           suffers an Event of Loss, upon  compliance  with the  requirements of
           Section 11.1, the balance, if any, of the Maintenance  Reserves shall
           be promptly paid over to Lessee. e. COST OF ENGINE REPAIRS.  Prior to
           start of a repair  of an  Engine  (after  disassembly)  Lessee  shall
           provide  Lessor  with a  written  estimate  of  total  repair  costs,
           including test cell run and consumable liquids.


SECTION 7. INSPECTION.

           During the Term,  Lessee  shall  furnish to Lessor  such  information
concerning the location,  condition, use and operation of the Items of Equipment
as Lessor may reasonably  request.  Lessee shall permit any person designated in
writing by Lessor to, at Lessor's expense,  visit and inspect (at any reasonable
time,   provided  that  such  inspection   shall  not  interfere  with  Lessee's
operational  commitments)  the  Items of  Equipment,  their  condition,  use and
operation and the records  maintained in connection  therewith  and, at Lessee's
expense,  to make  copies of such  records as Lessor may  reasonably  designate;
provided, however, Lessor shall not have access to information from the aircraft
data recorders (QAR, DFDR and CVR) until such  information has been disclosed by
the FAA.  Lessor  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.


SECTION 8. ADDITIONAL COVENANTS OF LESSEE.  Lessee covenants and agrees to the
following:

           a.  Lessee  is,  and shall  remain so long as it shall be the  Lessee
           under this Lease,  a "citizen of the United  States" as defined by 49
           USC ss.  40102(a)(15),  and Lessee is and shall  maintain and operate
           the Aircraft at all times as a Certificated Air Carrier;

           b. Lessee will not,  without prior written  notice to Lessor,  change
           its principal place of business or chief executive office if there is
           more than one place of business  and will  maintain  all records with
           respect to the  Aircraft  and the Engines at its  principal  place of
           business;

           c.  Lessee  shall not (i)  voluntarily  suspend its  operations  as a
           Certificated Air Carrier; or (ii) voluntarily or involuntarily permit
           to be revoked,  canceled or otherwise terminated all or substantially
           all of the  franchises,  concessions,  permits,  rights or privileges
           required for the conduct of business and  operations of Lessee or the
           free and continued use and exercise thereof;

           d. Lessee specifically  covenants that during the Term hereof it will
           not operate the  Aircraft to any  location  where such  operation  is
           prohibited by applicable law, rule or regulation.

           e.  Lessee  shall  pay or cause to be paid  promptly  when due all en
           route navigation  charges,  navigation  service charges (including to
           the extent  applicable  Eurocontrol  charges)  and all other  charges
           payable  in  respect  of  the  use of the  Aircraft  or for  services
           provided at any airport in respect of the Aircraft.  Lessee agrees to
           indemnify and hold the Lessor harmless in respect of all such charges
           in respect of the Aircraft.  This  indemnity  shall  continue in full
           force and effect notwithstanding the termination or expiration of the
           Term for any reason whatsoever or the return of the Aircraft but only
           with  respect  to  acts  or  events  occurring  on or  prior  to such


                                       21
<PAGE>

           termination,  expiration  or return.  Upon request of Lessor,  Lessee
           shall provide  Lessor with a letter  addressed to  Eurocontrol or any
           other relevant air traffic control authority pursuant to which Lessee
           authorizes the addressee to issue to Lessor a statement of account of
           all sums due by Lessee to the  authority in respect of the  operation
           of the Aircraft (and other aircraft owned or operated by Lessee).

           f.  Lessee  shall not  become a "tax  exempt  entity"  as  defined in
           Section 168(h) of the Internal Revenue Code.

           g. Lessee shall not permit the  predominant use of the Aircraft to be
           outside the United States within the meaning of Section 168(g) of the
           Internal  Revenue  Code  prior  to  the  seventh  anniversary  of the
           Delivery Date.

           h.  Lessee  will  make  no  claim  or  file  any  document  which  is
           inconsistent with the ownership of the Aircraft by the Lessor.

           i.  Lessee  will not alter or amend the  Tramco  Agreement  or the GE
           Agreement without the prior written consent of Lessor.

           j. Lessee will not operate or permit the  operation of the Engines at
           B3 or C1 thrust, except on an emergency basis.






SECTION 9.      REPLACEMENT AND POOLING OF PARTS;
           ALTERATIONS, MODIFICATIONS AND ADDITIONS.

      9.1.  REPLACEMENT  OF PARTS.  Lessee,  at its own cost and expense,  shall
promptly  replace all Parts  which may from time to time become worn out,  lost,
stolen,  destroyed,  seized,  confiscated,  damaged beyond repair or permanently
rendered unfit for use for any reason whatsoever.  In addition,  in the ordinary
course of maintenance,  service,  repair, overhaul or testing, Lessee may remove
any Part, whether or not worn out, lost, stolen, destroyed, seized, confiscated,
damaged  beyond  repair or  permanently  rendered  unfit for use;  provided that
Lessee  shall  promptly  replace  such  Part as  promptly  as  practicable.  All
replacement  Parts shall be free and clear of all Liens,  except those permitted
under  Section 9.3 hereof and shall be in as good  operating  condition  as, and
shall have a value and  utility and  modification  status 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.

      9.2. TITLE TO REPLACED AND  REPLACEMENT  PARTS.  All Parts removed from an
Airframe or an Engine  shall  remain the  property of Lessor and subject to this
Lease, no matter where located,  until such time as such Parts shall be replaced
by Parts  which have been  incorporated  or  installed  in or  attached  to such
Airframe  or Engine  and  which  meet the  requirements  for  replacement  Parts
specified above.  Immediately  upon any replacement Part becoming  incorporated,
installed or attached as above  provided,  without further act, (a) title to the
replaced Part shall  thereupon  vest in Lessee,  free and clear of all rights of
Lessor  and  Lessor  and free of all  Liens,  other  than  Permitted  Liens (not
including Lessor Liens); (b) such replaced Part shall no longer be deemed a Part
hereunder; (c) title to the replacement Part shall thereupon vest in Lessor; and


                                       22
<PAGE>

(d) such replacement Part shall become subject to this Lease and be deemed to be
a Part  hereunder  to the same extent as the Parts  originally  incorporated  or
installed in or attached to an Airframe or Engine.

      9.3.  POOLING.  Any replacement Part when  incorporated or installed in or
attached to an Airframe or Engine in  accordance  with Section 9.1 hereof may be
owned by another air carrier, subject to a normal pooling arrangement;  provided
that  Lessee,  at its expense,  as promptly  thereafter  as possible  either (a)
causes  title to such  replacement  Part to vest in  Lessor in  accordance  with
Section 9.2 by Lessee  acquiring  title thereto for the benefit of Lessor,  free
and clear of all Liens,  or (b) replaces  such  replacement  Part with a further
replacement Part owned by Lessee free and clear of all Liens.

           Any Part  removed  from an  Airframe or Engine as provided in Section
9.1 may be subjected by Lessee to a normal pooling arrangement  customary in the
airline  industry  entered into the ordinary  course of Lessee's  business  with
another air carrier;  PROVIDED that a Part  replacing such removed Part shall be
incorporated  or  installed  in or  attached  to  such  Airframe  or  Engine  in
accordance  with  Section 9.1 as promptly as possible  after the removal of such
removed Part.
      9.4.  ALTERATIONS,  MODIFICATIONS  AND  ADDITIONS.  Except as  provided in
Section  6.6  hereof,  Lessee  shall not make any  alteration,  modification  or
addition to any Airframe or any of the Engines,  without  Lessor's prior written
consent;  provided,  however,  Lessor's  consent  shall not be  required  if the
modification, alteration or addition has a cost (including cost of installation,
if  applicable) of less than $[ ]* and does not decrease the value or utility of
the Aircraft or Engine.  Lessor shall bear no liability  whatsoever for the cost
of  alterations,  modifications  or  additions  to the  Aircraft  whether due to
grounding  of any  Aircraft or any Engine or the  suspension  or  revocation  of
certification of any Aircraft or for any other cause.

      9.5. TITLE TO PARTS.  Subject to the provisions hereof, title to all Parts
incorporated or installed in or attached or added to each Aircraft as the result
of any  alteration,  modification  or addition,  or  otherwise  installed on the
Aircraft by Lessee and necessary for the  transportation  of persons or property
under the rules of the FAA,  shall,  without  further  act,  vest in Lessor  and
become subject to this Lease;  PROVIDED,  HOWEVER, that so long as no Default or
Event of Default shall have occurred and be  continuing,  at any time during the
Term,  Lessee may remove any Part from an Item of  Equipment,  provided that (a)
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 Item at the
time  of  delivery  thereof   hereunder  or  any  Part  in  replacement  of,  or
substitution  for, any such original  Part;  (b) such Part is not required to be
incorporated  or installed in or attached or added to such Item  pursuant to the
terms  hereof;  and  (c)  such  Part  can be  removed  from  such  Item  without
diminishing  or impairing the value,  utility or  airworthiness  which such item
would have had at such time had such  alteration,  modification  or addition not
occurred.  Upon the removal by Lessee of any such Part as above provided,  title
thereto shall, without further act, vest in Lessee and such Part shall no longer
be deemed a Part  hereunder.  Any Part not  removed by Lessee as above  provided
prior to the return to the respective Item to Lessor  hereunder shall remain the
property of Lessor and subject to this Lease.


SECTION 10.  TAXES.

      10.1.GENERAL.  Lessee  shall  pay,  assume  liability  for and  indemnify,
protect,  defend, save and hold Lessor,  Mortgagee and any permitted  successor,
assignee or transferee of any of the foregoing,  and any affiliate of any of the
foregoing with which such entity files a consolidated  or combined  return (each
an "Indemnitee"),  harmless from and against,  all taxes (including  value-added


                                       23
<PAGE>

taxes), fees (including license and registration fees), levies, imposts, duties,
charges or withholdings of any nature  whatsoever,  together with any penalties,
fines or interest thereon,  (all the foregoing being collectively called "Taxes"
and  each a  "Tax")  which  are  imposed  by any  government  (or any  political
subdivision  or fiscal or taxing  authority  thereof) and are imposed on or with
respect to, or are  measured  by, (a) this Lease,  (b) the  Aircraft or any Part
thereof,  (c) the Lessorship,  delivery,  possession,  use,  presence,  storage,
registration,  deregistration,  modification,  maintenance,  operation,  return,
import,  export,   subleasing,   repair,  overhaul,   transportation,   landing,
redelivery,  leasing or other disposition of the Aircraft or any Part or portion
thereof,  or (d) the  receipts,  earnings,  insurance  proceeds or other amounts
arising from the Aircraft or any Part,  or this Lease;  PROVIDED,  HOWEVER,  the
foregoing  indemnity shall not apply to: (i) Taxes imposed on or measured by the
net  income,  net  worth,  gross  receipts,  capital  or excess  profits  of any
Indemnitee by the  jurisdiction of  incorporation or principal place of business
of such Indemnitee, or where such Indemnitee is otherwise subject to taxation as
a result of transactions unrelated to the Aircraft or the Lease, unless such Tax
resulted   solely  from  the  operation  by  Lessee  of  the  Aircraft  in  such
jurisdiction;  (ii)  Taxes  imposed  with  respect  to any  period  prior to the
Delivery Date or the period after return of the Aircraft  pursuant to Section 15
hereof; (iii) Taxes imposed on or with respect to a transfer by an Indemnitee of
all or any part of its rights,  title and  interest in, to or under the Aircraft
(or any Part thereof,  except a transfer of a Part pursuant to Section 9 of this
Lease) or this Lease to any person or entity,  unless any such  transfer  occurs
because an Event of Default has occurred and is continuing, (iv) Taxes which any
Indemnitee  is subject to as a result of business or  transactions  unrelated to
the transactions contemplated by this Lease; (v) any Tax imposed on a transferee
of any  Indemnitee  to the extent such Tax exceeds  the amount  Lessee  would be
required to indemnify the  transferring  Indemnitee  hereunder;  (vi) any Tax or
penalty due to a failure by the Lessor,  after receipt of timely  written notice
thereof  from  the  Lessee  to  comply  with  any  certification,   information,
documentation,  notification or other reporting requirement which is required by
law or a  precondition  to exemption or other  relief from (or  reduction)  such
taxes;  (vii) any tax or penalty due to the Indemnitee's  willful  misconduct or
inaccuracy  of any  representation  of the  Indemnitee,  or  the  breach  of any
agreement of the Indemnitee,  in the Lease or any other Lease Documents;  (viii)
any increase in Taxes caused by a change of  jurisdiction  of  incorporation  or
place of business of an  Indemnitee  or a change in the place of any payment due
hereunder.

      10.2.WITHHOLDING TAXES. Notwithstanding anything to the contrary contained
in this  Section  10 (other  than  subsection  10.1(viii)  above),  if Lessee is
required by law to make any withholding from Rent or any other amount payable by
Lessee to an Indemnitee  under this Lease,  Lessee shall pay to such  Indemnitee
such additional  amount as may be necessary to enable such Indemnitee to receive
(after  such  withholding)  and retain an amount  equal to the full  amount then
payable to such Indemnitee absent such withholding. As soon as practicable after
Lessee makes any withholding from any amount payable to an Indemnitee under this
Lease,  Lessee shall  deliver to such  Indemnitee  a receipt or other  document,
reasonably  satisfactory to such Indemnitee and reasonably obtainable by Lessee,
evidencing  such  withholding  and the  payment  of the amount  withheld  to the
relevant governmental authority,  for the purpose of enabling such Indemnitee to
substantiate  a claim for credit or  deduction  for income tax  purposes  of the
amounts so withheld.  If Lessee pays to Lessor pursuant to this Section 10.2 any
additional  amount  with  respect  to any  withholding  for which  Lessee is not
required by Section  10.1 hereof to  indemnify  Lessor,  Lessor shall repay such
additional  amount  to Lessee  within 30 days  after  Lessor  receives  Lessee's
written request therefor  accompanied by the receipt or other document  referred
to in the  preceding  sentence,  together with interest on such amount repaid at
LIBOR as in effect  from time to time,  and in such  case,  Lessee  shall not be


                                       24
<PAGE>

further  obliged  to pay  such  additional  amount  in  the  future  once  it is
determined that Lessee is not required to indemnify for such  withholding.  This
Section 10.2 shall not apply to any withholding tax imposed by the United States
of America.

      10.3.AMOUNT OF INDEMNITY.  Each indemnity  provided for in this Section 10
or Section 13 below,  shall be in an amount which, after taking into account all
taxes,  fees or other  charges  payable or imposed with respect  thereto or as a
result of the receipt thereof by any Indemnitee in any jurisdiction  (whether or
not excepted  above),  shall be equal to the amount of such indemnity  otherwise
payable  under this  Lease.  Any  payment  required  to be made by Lessee  under
Sections 10.1 or 10.3 shall be due and payable within 30 days following Lessee's
receipt of Lessor's written demand therefor  (accompanied by a written statement
of Lessor  describing in reasonable detail the Taxes for which the Indemnitee is
demanding an indemnity and the  computation of the amount of the indemnity being
demanded), subject to the provisions of Section 10.4.

      10.4.CONTEST.  If a claim is made against any  Indemnitee for any Tax that
is subject to  indemnification  under this  Section 10,  Lessor will give Lessee
written  notice of such claim.  If Lessee so requests in writing  within 30 days
after receipt of such notice,  the Indemnitee shall permit Lessee to contest the
claim in the name of such  Indemnitee  or in the name of  Lessee,  to the extent
permitted by law. However,  if such claim together with other claims which could
be made with respect to other  transactions  to which such  Indemnitee is then a
party could (if sustained) have an adverse effect on such Indemnitee's  business
or  financial  affairs  (a  "Special  Claim"),  or (b) if  Lessee  shall  not be
permitted  by law to contest a claim  (other than a Special  Claim) on behalf of
such  Indemnitee,  then such Indemnitee  shall contest such claim in good faith.
Notwithstanding the foregoing, no claim shall be contested unless and until: (a)
the Indemnitee shall have received (i) an indemnity  reasonably  satisfactory to
it for all  expenses  reasonably  expected  to be paid in  contesting  the claim
(including  attorneys' and accountants' fees and disbursements) and (ii) written
acknowledgment by Lessee of its liability  hereunder (if such contest is decided
adversely) in respect of such Taxes; (b) the action to be taken will not involve
any  material  risk of the sale,  forfeiture  or loss of, or the creation of any
Lien  (except a Lien  which  Lessee  shall  have  bonded in an amount and manner
reasonably  satisfactory  to Lessor) on, the Aircraft or any part thereof or any
interest  therein;  (c) if such contest shall be conducted in a manner requiring
the payment of the claim,  Lessee shall have advanced the amount  required on an
after-tax  basis;  (d) no Default or Event of Default shall have occurred and be
continuing  and Lessor shall be receiving all amounts of Rent when due,  without
reduction by reason of any Taxes;  and (e) if such claim is a Special Claim, and
if Lessor  shall have  received a legal  opinion (at the expense of Lessee) from
counsel  satisfactory  to Lessor  indicating  that a  reasonable  basis for such
contest exists. Lessor and Lessee shall in good faith consider the other party's
views  regarding the conduct of the contest.  Lessor and Lessee shall provide to
each other, upon request, such reasonably obtainable  information and such other
reasonable  assistance  as may be  necessary  or  advisable  for  the  effective
evaluation or conduct of such contest.  Notwithstanding the foregoing provisions
of this Section 10.4, if at any time Lessor waives its right of  indemnification
under  this  Section  10 in respect of a claim,  or if,  after  having  received
payment of  indemnification  from  Lessee  hereunder  in respect to such  claim,
Lessor  tenders  such  payment to Lessee,  then Lessee  shall not be entitled to
contest, or to continue to contest, any such claim.

      10.5.TAX  RETURNS.   Lessee  will  provide  such  information  as  may  be
reasonably  requested by Lessor and  reasonably  obtainable  by Lessee to enable
Lessor to fulfil its tax filing  requirements  with respect to the  transactions
contemplated  hereby.  In the  event  that any  return,  statement  or report is
required to be made or filed with respect to any Tax required to be  indemnified
against by Lessee  under this Section 10,  Lessee  shall  notify  Lessor of such


                                       25
<PAGE>

requirement  and (a) to the extent  permitted by law and  requested by Lessor or
required by law, make and file in its own name such return,  statement or report
in such manner as will show the Lessorship of the Aircraft in Lessor and furnish
Lessor with a copy of such return, statement or report or (b) where such return,
statement or report is required to be in the name of or filed by Lessor, prepare
and furnish such return, statement or report for filing by Lessor in such manner
as shall be  satisfactory  to Lessor  and send the same to Lessor  for filing no
later than 30 days prior to the due date.  Where  Lessor is  required to make or
file a return,  statement or report  reflecting items of Equipment other than or
in addition to Taxes indemnified against by Lessee under this Section 10, Lessee
shall,  upon  Lessor's  request,  provide  Lessor  with  information,  within  a
reasonable  time,  sufficient  to permit such return,  statement or report to be
properly made and timely filed.

      10.6.MUTUAL ASSISTANCE.  Lessor and Lessee agree to consider in good faith
(but without any obligation to agree thereto) any  reasonable  modifications  of
the transaction described in this Lease that would reduce or eliminate any Taxes
imposed on either party as a result of such transaction.

      10.7 REFUND OF  INDEMNITY.  If any amount paid under this Section 10 to an
Indemnitee is later  recovered in whole or in part,  whether by way of refund of
tax or utilization of a tax credit  generated by the Tax indemnified  hereunder,
the  Indemnitee  shall repay such amount,  together with such interest as may be
paid by the taxing  authority,  to Lessee.  No refund to Lessee shall exceed the
sum of the indemnity payments to such Indemnitee hereunder.

      10.8  MACRS  INDEMNITY.  Lessee  will  indemnify  the Lessor for the loss,
reduction  or  recapture of  deductions  with respect to the Aircraft  otherwise
available to the Lessor under Section 168 of the Internal  Revenue Code of 1986,
as amended,  caused by (i) the Lessee's or any  sublessee's  being a "tax-exempt
entity"  within  the  meaning  of Code  Section  168(g)  or (ii)  the use of the
Aircraft by Lessee or any sublessee  "predominantly  outside the United  States"
within the meaning of Code Section 168(h).

[Customary  exceptions  and contest  rights and provision for the payment to the
Lessee by the Lessor of any tax  benefits  available  to the Lessor  (whether by
deduction, credit or otherwise) as the result of the indemnified matter.]


SECTION 11.  EVENT OF LOSS.

      11.1.WITH RESPECT TO THE AIRCRAFT. Upon the occurrence of an Event of Loss
with respect to the Aircraft, Lessee shall forthwith (and in any event within 10
days after such  occurrence)  give Lessor  written notice of such Event of Loss,
and Lessor and Lessee shall proceed  diligently  and  cooperate  fully with each
other in the recovery of any and all proceeds of insurance  applicable  thereto.
On the earlier of the date of receipt of proceeds of  insurance  or the 90th day
following the Event of Loss Lessee shall pay or cause to be paid to Lessor:  (a)
the Insured Value of the  Aircraft;  (b) all other amounts of Rent which are due
and unpaid hereunder.

           At such time as Lessor or  Mortgagee  shall have  received the entire
Insured  Value for the  Aircraft  and all  accrued and unpaid Rent and any other
amounts due Lessor  hereunder,  Lessor  shall  transfer  to Lessee all  Lessor's
right,  title, and interest,  "as-is,  where-is,"  without recourse or warranty,
express or  implied,  in and to (a) the  Aircraft,  (b) all claims for damage to
such Items, if any, against third persons arising from the Event of Loss (unless
any  insurance  carrier  requires  that such claims be assigned to it),  (c) all
rights  to any  insurance  claims  and  proceeds  under  all  insurance,  except


                                       26
<PAGE>

liability insurance, maintained by Lessee hereunder, all without representation,
recourse or warranty of any kind whatsoever, and (d) the Term of the Lease shall
end.

      11.2.WITH  RESPECT TO AN ENGINE.  Upon the  occurrence of an Event of Loss
with respect to an Engine under circumstances in which there has not occurred an
Event of Loss with respect to the Aircraft,  Lessee shall  forthwith (and in any
event within 10 days after such  occurrence)  give Lessor written notice thereof
and Lessee  shall  replace  such Engine as soon as  reasonably  possible by duly
conveying to Lessor, free and clear of all Liens, title to another engine of the
same or an improved model and suitable for  installation and use on the Airframe
with the other  Engine,  which  engine  shall have a value and  utility at least
equal to, and be in as good  operating  condition as, the Engine with respect to
which such Event of Loss shall have  occurred,  assuming  such Engine was of the
value and  utility  and in the  condition  and repair as  required  by the terms
hereof  immediately  prior  to the  occurrence  of  such  Event  of  Loss.  Such
replacement  engine  shall be deemed  an  "Engine"  as  defined  herein  for all
purposes  hereunder.  Lessee  agrees  to  promptly  notify  Lessor  of any  such
substitution,  provide Lessor with an officer's  certificate  demonstrating full
compliance  with this  Section  11.2 and Lessee  agrees to take such  action and
execute  such  documents,  including  a  warranty  bill of sale,  as Lessor  may
reasonably  request in order that any such replacement  Engine shall be duly and
properly  titled in the name of the  Lessor  and  leased  hereunder  to the same
extent as any Engine replaced  thereby.  Lessor shall take such action and shall
execute such documents as are reasonably necessary to convey the Engine replaced
pursuant to the preceding sentence to Lessee or its insurer.

      11.3.APPLICATION  OF  PAYMENTS  FROM  GOVERNMENTAL  AUTHORITIES.  Payments
received  by Lessor or Lessee  from any  governmental  authority  or entity with
respect to an Event of Loss resulting  from the  condemnation,  confiscation  or
seizure of, or  requisition  of title to an Aircraft,  an Airframe or any of the
Engines,  shall be retained by Lessor,  if received by Lessor,  or promptly paid
over to Lessor, if received by Lessee, up to the Insured Value (plus any amounts
of Rent then due and owing). At such time as Lessor has received such amounts in
full,  Lessor shall promptly  remit the excess,  if any, of such payments to the
Lessee. Payments received by Lessor or Lessee from any governmental authority or
entity with respect to a requisition  of use during the Term of an Aircraft,  an
Airframe  or any of the  Engines  shall be paid to or  retained  by Lessee,  and
Lessee's  obligation to make all payments of Rent shall  continue  undiminished.
Payments  received by Lessor or Lessee with respect to periods  after the end of
the Term shall be paid to (or retained by) Lessor.


SECTION 12.  INSURANCE.

      12.1.PUBLIC  LIABILITY,   BODILY  INJURY  AND  PROPERTY  DAMAGE  LIABILITY
INSURANCE.  Lessee, at its own expense, shall maintain or cause to be maintained
in effect third party aircraft liability insurance (which includes coverage with
respect  to  liabilities  arising  while  the  Items  of  Equipment  are  not in
operation),  passenger legal liability  insurance and property damage  liability
insurance,  including  contractual  liability insurance and war risk,  hijacking
(air  piracy),  confiscation,  nationalization,   expropriation  (excluding  the
Government of the United States of America) and related perils coverages, during
the Term in an amount not less than the  greater  of (a) $[ ]*, per  occurrence,
combined single limit or (b) the amount normally  carried by Lessee on its other
owned or leased aircraft,  for any one accident,  or series of accidents arising
out of any one event, with respect to the items of Equipment.  All such policies
shall be maintained in effect directly with  independent  insurers of recognized


                                       27
<PAGE>

reputation and financial responsibility,  reasonably satisfactory to Lessor. Any
policies of  insurance  carried in  accordance  with this  Section  12.1 and any
policies  taken out in  substitution  or  replacement  for any of such  policies
shall:  (i)  name  Lessor  and all  other  Additional  Insureds,  as  additional
insureds;  (ii)  provide  that in respect  of the  interests  of the  Additional
Insureds  such  policies  of  insurance  shall  insure the  Additional  Insureds
regardless  of  any  breach  or  violation  of  any  warranty,  declarations  or
conditions  contained  in such  policies by any other  insured  party other than
Additional  Insureds;  (iii) provide that if the insurers  cancel such insurance
for any  reason  whatever,  or the same is allowed  to lapse for  nonpayment  of
premium, or if there is any material change in policy terms and conditions, such
cancellation,  lapse or change  shall not be  effective  until 30 days (and with
respect to war risk insurance,  such shorter period as shall be customary in the
International  Aviation  market  for such  insurance  in such area of the world)
after prior written notice to the Additional Insureds,  in care of the Lessor at
the address  shown in Section 18.2 below,  from such insurers or brokers of such
cancellation,  lapse or change;  (iv) be primary  without right of  contribution
from any other insurance which may be available to any Additional  Insured;  (v)
expressly  provide  that all of the  provisions  thereof,  except  the limits of
liability,  shall operate in the same manner as if there were a separate  policy
covering each insured, but this provision shall not operate to include any claim
arising in respect of loss or damage to the  Aircraft or Engines  insured  under
the hull insurance provided in Section 12.2 below, and provided further that the
foregoing  shall not  increase the total  liability  of the insurers  beyond the
limits of liability  stated in the Policy;  (vi) provide that the insurers agree
to waive any right of subrogation  or setoff,  counterclaim  or other  deduction
against any  Additional  Insured;  and (vii)  provide for world wide coverage in
full  force and  effect  throughout  any  geographical  areas  traversed  by the
Aircraft or Engines.  Without increasing the scope of coverage under the airline
liability  policies,  the insurers thereunder shall acknowledge the existence of
this  Lease  and the  Mortgage  and  provide  coverage  for the  indemnification
provisions of this Lease.  Insurers  shall also  acknowledge  that Lessor has no
operational control over the Aircraft.

      12.2.INSURANCE AGAINST LOSS OR DAMAGE TO THE AIRCRAFT.  Lessee, at its own
expense,  shall  maintain  directly  in  effect  with  independent  insurers  of
recognized reputation and financial  responsibility,  reasonably satisfactory to
Lessor:  (a) all-risk  ground and flight  aircraft hull insurance  covering each
Aircraft; (b) fire and extended perils coverage with respect to Engines or Parts
while  removed from the  Aircraft;  and (c) war risk,  hijacking  (air  piracy),
confiscation,  nationalization,  expropriation  (excluding the Government of the
United States of America) and related perils coverages. All such insurance shall
be in full force and effect  throughout any geographical  areas traversed at any
time by each Aircraft or Engines, shall be payable in Dollars and shall be in an
amount  of not less  than the  Insured  Value.  Any hull  insurance  carried  in
accordance  with this Section 12.2 shall not contain a provision for  deductible
or self-insurance amount in excess of $[ ]*. Each Engine, after removal pursuant
to  Section  6.1,  shall be  insured  for not less than $[ ]* under  the  policy
referenced  in 12.2(b)  above.  Any  policies  carried in  accordance  with this
Section  12.2 shall (i) name the Lessor,  the Lessee and the  Mortgagee  as loss
payee(s); (ii) provide that if such insurance is cancelled or materially changed
for any  reason  whatever,  or the same is allowed  to lapse for  nonpayment  of
premium,  such cancellation,  change or lapse shall not be effective for 30 days
(and  with  respect  to war risk  insurance,  such  shorter  period  as shall be
customary in the  International  Aviation market for such insurance in such area
of the world) after prior written  notice to the  Additional  Insureds from such
insurers of such  cancellation  or lapse or material  change in policy terms and
conditions;  (iii)  provide that in respect of the  interests of the  Additional
Insureds  such  policies  of  insurance  shall  insure each  Additional  Insured
regardless  of  any  breach  or  violation  of  any  warranty,  declarations  or
conditions  contained  in such  policies  by any other  insured  other  than the
Additional Insureds; (iv) shall include waivers by the insurers of any rights of


                                       28
<PAGE>

subrogation or setoff,  counterclaim or other deduction whether by attachment or
otherwise,  in respect of any  liability of Lessor except in respect of premiums
in respect of the Aircraft  which are the subject of this Lease;  (v) be primary
without right of contribution from any other insurance which may be available to
any Additional Insured;  and (vi) provide that in the event of a dispute between
the insurance and reinsurance  underwriters subscribing to the Hull Risks Policy
and the insurance and reinsurance  underwriters  subscribing to the Hull War and
Allied Risks Policy each policy shall subscribe to 50% of the agreed valid claim
in  accordance  with "50/50"  clause AVS 103.  Without  increasing  the scope of
coverage under the airline  liability  policies,  the insurers  thereunder shall
acknowledge  the  existence of this Lease and the Mortgage and provide  coverage
for  the  indemnification   provisions  of  this  Lease.   Insurers  shall  also
acknowledge that Lessor has no operational control over the Aircraft.

      12.3.NOTICE OF ADDITIONAL PARTIES. Lessor agrees to provide written notice
to Lessee of the name,  address and telephone and fax numbers of all  Additional
Insureds at the inception of this Lease and at the time of any change therein.

      12.4.APPLICATION  OF  PROCEEDS  IN AN EVENT OF LOSS.  All  payments  under
insurance policies required to be maintained hereunder and received by Lessee or
by Lessor as the result of the  occurrence  of an Event of Loss shall be applied
as follows:

           a. If such  payments are received  with respect to an Airframe (or an
           Airframe and the Engines or engines  installed  thereon),  Lessor and
           Lessee shall proceed  diligently and cooperate  fully with each other
           in the  recovery  of any and all  proceeds  of  insurance  applicable
           thereto,  and so much of such insurance proceeds as shall not exceed,
           in the aggregate, the sums due under Section 11.1 above shall be paid
           first to Mortgagee,  if any, as first  priority  loss payee,  then to
           Lessor as second  priority  loss  payee,  in  accordance  with  their
           respective interests.

           b. If such  payments are received with respect to an Engine under the
           circumstances  contemplated by Section 11.2 hereof,  provided that no
           Event of Default  exists and is  continuing,  such payments  shall be
           paid over to, the Lessee,  provided  that the Lessee shall have fully
           performed  the terms of  Section  11.2  hereof  with  respect  to the
           provision of a satisfactory replacement Engine.

      12.5.APPLICATION  OF  PROCEEDS  IN THE  ABSENCE  OF AN EVENT  OF LOSS.  As
between Lessor and Lessee, the insurance payments of any property damage loss to
an Aircraft or any Engine not constituting an Event of Loss with respect thereto
will be applied as follows:
           a. in respect of a claim for damage not  exceeding  $[ ]* any payment
           from the insurers shall be released  directly to Lessee, or where the
           work has been contracted out, to the repairers; and

           b. in respect of a claim where damage  exceeds $[ ]* any payment from
           the  insurers  shall  be  payable  to  Mortgagee  and  Lessor  or its
           assignee(s) up to and including the amount of the Insured Value,  but
           will be paid over to Lessee in  reimbursement  for completed  repairs
           or, where the approved  work has been  contracted  out,  will be paid
           over to the repairer.

           Any  amount  referred  to in this  Section  12.5  which is payable to
Lessee  shall not be paid to Lessee if at the time of such  payment  an Event of
Default declared to Lessee's Insurers shall have occurred and be continuing, but


                                       29
<PAGE>

shall be held by Lessor as security  for the  obligations  of Lessee  under this
Lease  and such  amount  shall be paid to Lessee at such time as there no longer
exists any Default or Event of Default.

      12.6.REPORTS,  ETC. Lessee and Lessee's independent insurance broker shall
advise  Lessor in writing  promptly of any default in the payment of any premium
and of any other act or omission on the part of Lessee which might invalidate or
render unenforceable, in whole or in part, any insurance on the Aircraft. At the
Delivery  Date and at least 10 days prior to the renewal  date of any  insurance
policy  maintained  with  respect to the  Aircraft  pursuant to this Section 12,
Lessee shall provide Lessor with:

           a.   the insurance  certificates executed by an independent aircraft
           insurance broker together with their letter of undertaking; and

           b.  the  written  opinion  of  Lessee's  insurance  broker  that  the
           insurance maintained by Lessee and its insurers is in compliance with
           the provisions of this Lease.

      12.7.LESSEE'S  ADDITIONAL  INSURANCE.  Lessee shall not place insurance on
the Aircraft in excess of the amounts  specified in Section 12.2 beyond the next
policy renewal date without the prior written approval of Lessor,  which consent
shall not be  unreasonably  withheld.  Any proceeds of insurance  maintained  by
Lessee in excess of the amount  specified in Section 12.2,  assuming  Lessor has
consented  thereto,  shall be paid to Lessee as soon as practical after the date
such  insurance  proceeds are received by Lessor,  Lessor or  Mortgagee.  In any
event Lessor shall be entitled to receive all  insurance  proceeds  derived from
insurance  coverage  paid for by Lessor.  No  additional  insurance  procured by
Lessee shall have the effect of suspending,  impairing, defeating,  invalidating
or rendering  unenforceable or reducing, in whole or in part, the coverage of or
the proceeds payable under any insurance  required to be provided and maintained
by Lessee pursuant to this Section 12.

      12.8.LESSOR  NOT LIABLE FOR  PREMIUMS.  All policies of insurance  carried
hereunder  shall clearly  state that neither  Lessor nor any assignee of Lessor,
shall  have  any  liability   for  or  obligation   with  respect  to  premiums,
commissions, assessments or calls, but shall have the right to pay the same with
respect to the Aircraft and/or Engines. Lessor shall have the right, but not the
obligation,  to place  additional  insurance  on the Aircraft in such amounts as
Lessor in its sole discretion deems proper; provided, however, no such insurance
shall impair,  defeat or invalidate  the coverage  effected  pursuant to Section
12.2 above and such additional insurance shall be at Lessor's sole expense.

      12.9.CONTINUING  INSURANCE.  Lessor  may  require  Lessee to effect and to
maintain  insurance  after  the  expiration  of the  Term  with  respect  to its
liability  under the  indemnities  in Section  13 for such  period as Lessor may
require (but in any event not after the second anniversary of the termination of
the leasing of the Aircraft under this Lease, which provides for each Indemnitee
to be named as additional insured.  Lessee's obligation under this Section shall
not be affected by Lessee ceasing to be lessee of the Aircraft and/or any of the
Indemnities ceasing to have any interest in the Aircraft.


                                       30

SECTION 13.  GENERAL INDEMNIFICATION.

      13.1  SCOPE.  Lessee  shall  hold  Lessor,  Mortgagee  and GATX and  their
respective directors,  officers,  agents,  shareholders contractors,  employees,
successors,  assigns and servants (each an  "Indemnitee")  harmless from any and
all claims, demands, suits, causes of action and all legal proceedings,  whether
civil or criminal,  damages, losses, liabilities (including, but not limited to,
strict liability in tort), obligations,  penalties, judgments or fines and other
sanctions,  and any  costs  and  expenses  in  connection  therewith,  including
reasonable  legal fees and expenses of whatever kind and nature  ("Loss")  which
may result from or arise out of (a) the condition,  use or operation  during the
Term of any Item of  Equipment  either in the air or on the  ground,  or (b) any
maintenance,   service,  repair,  overhaul,  possession,  delivery,  performance
management,  registration,  control,  return or testing  of any Item  during the
Term,  whether  or not such  Item is at the time in the  possession  of  Lessee;
provided,  however,  that the Lessee  shall not be  required  to  indemnify  any
Indemnitee  for any Loss, (i) to the extent that such Loss is caused by the acts
or events which occur after full and final  compliance  by Lessee with all terms
of the Lease,  unless attributable to acts,  omissions,  circumstances or events
occurring  during the Term,  (ii) to the extent that such Loss is caused by acts
or events which occur  following  expiration or termination of the Lease, or the
taking of  possession of the Aircraft by any  Indemnitee  pursuant to Section 17
hereof,  (iii) which is a Tax or a loss of tax benefit (it being understood that
Section 10 provides for Lessee's  liability with respect to Taxes),  (iv) to the
extent that such Loss results from the willful misconduct of any Indemnitee,  or
(v) to the  extent  that  such  Loss  results  from any  breach by Lessor of any
representation or warranty in Section 5.1 contained herein. Upon payment in full
to any party indemnified  hereunder of any indemnities contained in this Section
13 by Lessee,  Lessee shall be subrogated to all rights and remedies  which such
indemnified party has or may have against  manufacturers of the relevant Item or
any other person. Lessor shall notify Lessee promptly of any such Loss and in no
event later than 30 days after the Lessor has notice thereof.

      13.2.LESSEE'S RELEASE.  Lessee hereby waives and releases any claim now or
hereafter  existing  against  any  Indemnitee  on account of any and all claims,
demands,  suits,  causes of action and all legal  proceedings,  whether civil or
criminal,  damages, losses,  liabilities (including,  but not limited to, strict
liability  in  tort),  obligations,  penalties,  judgments  or fines  and  other
sanctions,  and any  costs  and  expenses  in  connection  therewith,  including
reasonable legal fees and expenses of whatever kind and nature, which may result
from or arise out of injury to or death of  personnel of Lessee or its agents or
contractors  or loss or damage to  property  of Lessee or the loss of use of any
property  which  may  result  from or  arise  out of (a) the  condition,  use or
operation during the Term of any Item of Equipment,  either in the air or on the
ground, or (b) any maintenance, service, repair, overhaul, possession, delivery,
performance  management,  registration,  control,  return or testing of any Item
during the Term,  whether or not such Item is at the time in the  possession  of
Lessee.  The foregoing  waiver and/or release shall not apply to injury,  death,
loss or  damage  solely  resulting  from  (i) the  gross  negligence  or  wilful
misconduct of such Indemnitee or (ii) the breach by Lessor of any representation
or warranty contained in Section 5.1 above.

      13.3.CONTEST. If Lessee is not permitted to contest in its own name and if
an Indemnitee is unable to assign to Lessee  whatever right such  Indemnitee may
have to bring or defend such an action,  then if requested by Lessee in writing,
Lessor  shall  upon  receipt  of an opinion of  Lessee's  counsel  stating  that
reasonable grounds exist to take the action requested, in good faith contest the

Amount") by (a) resisting payment thereof,  (b) not paying the same except under
protest if protest is  necessary  and proper,  or (c) if payment is made,  using
reasonable efforts to obtain a refund in appropriate  administrative or judicial
proceedings;  provided,  however, that Lessor need not contest the applicability

therein, except Permitted Liens. Lessee shall promptly, at its own expense, take
such action as may be  necessary  to duly  discharge  any such Lien not excepted
above if the same shall arise at any time with respect to any Item of Equipment.
As Lessor may reasonably  request from time to time due to changes in applicable
law or changes in other  circumstances  Lessee  shall  provide  Lessor  with the
written  opinion of independent  counsel  reasonably  satisfactory  to Lessor or
other written evidence  satisfactory to Lessor to the effect that, based upon an

SECTION 17.     RIGHTS AND REMEDIES.

      17.1.REMEDIES. Upon the occurrence of any Event of Default and at any time
thereafter so long as the same shall be  continuing,  Lessor may, at its option,
declare  this  Lease to be in  default  and at any time  thereafter,  so long as
Lessee shall not have  remedied all  outstanding  Events of Default,  Lessor may
exercise one or more of the following remedies with respect to any or all of the
Items of Equipment as Lessor, in its sole discretion, shall elect, to the extent
available  and  permitted  by, and  subject  to  compliance  with any  mandatory
requirements of, applicable law then in effect:

           a. Subject to Section  4.4,  apply all or any portion of the Security
           Deposit to Lessor's damages  attributable to such Event of Default or
           to the costs of curing such Event of Default;  provided,  however the
           Event of  Default  shall  continue  until  the  Security  Deposit  is
           restored to its original amount.

           b. Terminate this Lease and demand that Lessee, and Lessee shall upon
           written demand of Lessor and at Lessee's  expense,  forthwith  return
           all items of Equipment to Lessor in the manner and condition required
           by,  and  otherwise  in  accordance  with all of the  provisions  of,
           Section 15 hereof as if the items of Equipment were being returned at
           the end of the Term; or Lessor may enter upon the premises  where the
           items of Equipment are located and take  immediate  possession of and
           remove the same by summary  proceedings  or  otherwise,  all  without
           liability  for or by  reason of such  entry or  taking of  possession
           whether  for the  restoration  of damage to  property  caused by such
           taking or otherwise.

           c. Proceed by appropriate  court action or actions,  either at law or
           in  equity,  to  enforce  performance  by  Lessee  of the  applicable
           covenants  of this  Lease  and to  recover  damages  for  the  breach
           thereof.

           d. In  addition to all other  legal and  equitable  rights of Lessor,
           upon  notice to Lessee,  Lessor  may,  following  an Event of Default
           lease  the  Aircraft  to  any  third  party  upon  such  commercially
           reasonable terms and conditions as Lessor may determine and apply the
           rental therefrom to any amounts due to Lessor as provided herein.

           The total  proceeds of such lease less expenses of Lessor  (including
           attorneys'  fees),  to the extent  actually  received and retained by
           Lessor,  shall be  applied  to the  total  amount  due to  Lessor  as
           provided  herein  and  Lessee  shall  immediately  pay to Lessor  any
           deficiency.

           e.  On the  date  on  which  the  Lessor  shall  become  entitled  to
           repossession  of the  Aircraft,  Lessor,  in  addition  to all  other
           remedies herein provided, may by notice to Lessee, demand that Lessee


                                       35
<PAGE>

           pay,  and Lessee  shall pay,  on the first  Basic Rent  payment  date
           following  said  notice,  (1) any  due  and  unpaid  Basic  Rent  and
           Supplemental Rent,  together with interest at the Incentive Rate from
           the due date to the date the  same are  paid,  and (2) as  liquidated
           damages for loss of a bargain and not as a penalty,  an amount  equal
           to the  difference  between (i) the sum of all remaining  payments of
           Basic  Rent  falling  due  hereunder  after the date of said  notice,
           discounted to the date of said notice at seven percent per annum on a
           monthly basis (and assuming that the remaining payments of Basic Rent
           shall be in identical amounts as that payment falling due immediately
           prior to the Event of  Default),  and (ii) the Fair Rental  Value (as
           determined  by  an  independent   aviation  appraiser  of  recognized
           standing  selected by Lessor) of the Aircraft for the remaining Term,
           discounted  at the same rate and  frequency  specified  in (i) above;
           provided,  however,  if Lessor has  already  leased the  Aircraft  as
           permitted  by Section  17.1(d)  above,  the rental  specified in said
           lease shall be conclusive as to the "fair market rentals".

      17.2.FURTHER  RIGHTS.  Lessee  shall be liable for any and all unpaid Rent
and for all  reasonable  legal fees and other  costs and  expenses  incurred  by
reason of the  occurrence  of any Event of Default or the  exercise  of Lessor's
remedies  with respect  thereto,  including  all costs and expenses  incurred in
connection  with the return of any Item in accordance  with the terms of Section
15  hereof  or in  placing  such Item in the  condition  and with  airworthiness
certificates as required by said Section.

      17.3.REMEDIES  CUMULATIVE.  Except  as  otherwise  expressly  provided  in
Section 17.1 hereof,  no remedy referred to in this Section 17 is intended to be
exclusive,  but 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 or 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.  No  express  or implied  waiver by Lessor of any Event of
Default  shall in any way be, or be  construed  to be, a waiver of any future or
further Event of Default.


SECTION 18.     MISCELLANEOUS.

      18.1.CONSTRUCTION AND APPLICABLE LAW. Any provision of this Lease 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  hereof,  and any such  prohibition  or
unenforceability   in  any   jurisdiction   shall  not   invalidate   or  render
unenforceable such provision in any other jurisdiction.  No term or provision of
this Lease may be changed, waived,  discharged or terminated orally, but only by
a written  instrument  signed by the party against which the  enforcement of the
change,  waiver,  discharge or termination is sought. The captions in this Lease

construction,  validity and  performance,  but not  including  the choice of law
provisions thereof.

      18.2.NOTICES.  All  notices  provided  for herein  shall be in writing and

or to such other address as any party may designate for itself by written notice
to the other party.

      18.3.LESSOR'S  RIGHT TO  PERFORM.  If Lessee  fails to perform  any of its
obligations hereunder,  Lessor may discharge such obligation,  and the amount of
the  expenses of Lessor  incurred in  connection  with such  discharge  shall be
deemed Supplemental Rent, payable by Lessee upon demand.

      18.4.ASSIGNMENT  BY  LESSOR.  Lessor  shall  have  the  absolute  right to
transfer or assign to any person,  firm,  corporation or other entity any or all
of  Lessor's  rights,  obligations,  benefits  and  interests  under this Lease,
including,  without  limitation,  the right to receive Rent or any other payment
due under  this  Lease,  the right to  transfer  or assign  title to any Item of
Equipment  or to transfer or assign the right to purchase  any item of Equipment
and the right to make all waivers and agreements,  to give all notices, consents
and releases,  to take all action upon the occurrence of an Event of Default, or
to do any and all other  things  which  Lessor is or may become  entitled  to do
under this  Lease;  PROVIDED,  HOWEVER,  that  Lessor  shall not have the right,
without Lessee's prior written consent,  to transfer or assign any or all of its
rights,  title or  interest in the  Aircraft  or this Lease to United  Airlines,
Delta Air Lines, Southwest Airlines, or American Airlines; and, PROVIDED FURTHER
that any  transferee of Lessor's  entire  interest shall be an entity with a net
worth of at least $[ ]*, and, PROVIDED FURTHER that no such assignment by Lessor
shall have any impact on Lessee's  maintenance  or  operation  of the  Aircraft.
Lessee acknowledges that, if Lessor should sell or transfer to a third party all
of  Lessor's  interest  under this Lease and in the items of  Equipment,  Lessor
shall  thereupon be relieved of all of its  obligations  hereunder  and Lessor's
transferee  shall succeed to all of Lessor's  rights,  interests and obligations
under this  Lease as though  Lessor's  transferee  had been the  initial  lessor
hereunder;  provided, however, that, in the event of a transfer or assignment of
a  security  interest  in any  item of  Equipment  Lessor  shall  remain  liable
hereunder.  Any  assignment,   pledge  or  other  conveyance,  for  security  or
otherwise,  of this Lease by Lessor  shall be subject to Lessee's  rights  under
this Lease and shall not be  effective  unless and until  Lessee shall have been
given notice of such assignment  identifying the assignee or transferee  hereof.
No assignment or transfer  permitted  hereby shall increase  Lessee's  financial
obligations to Lessor hereunder, nor shall it serve to otherwise increase in any
material respect Lessee's obligations when compared with those obligations which
would have arisen had such  assignment  or transfer  not  occurred,  or serve to
decrease Lessee's rights, hereunder.

      18.5.SERVICE  OF PROCESS;  WAIVER OF  IMMUNITIES.  Lessee (a)  irrevocably
submits  itself to the  nonexclusive  jurisdiction  of the Supreme  Court of the
State of New York, New York County,  of the United States District Court for the
Southern  District  of New York for the  purpose  of any  suit,  action or other

proceeding arising out of this Lease or any other Lease Document, or the subject
matter  hereof or  thereof  or any of the  transactions  contemplated  hereby or
thereby,  brought by Lessor or its  successor,  subrogees  or  assigns;  and (b)
irrevocably  agrees that all claims in respect of such action or proceeding  may
be heard and  determined in such New York State or United States  Federal court.
Lessee  consents to service of process in any suit,  action or other  proceeding
arising  out  of  this  Lease  or  the  subject  matter  hereof  or  any  of the
transactions contemplated hereby in such New York State or United States Federal
courts and irrevocably  designates and appoints the person  specified in Section
5.2(g)  hereof  (herein  referred to as  "Agent"),  as its  attorney-in-fact  to
receive service of process in such action,  suit or proceeding,  it being agreed
that service upon such  attorney-in-fact  shall  constitute  valid  service upon
Lessee  and its  successors  and  assigns.  Lessee  agrees  that  (x)  the  sole
responsibilities  of Agent shall be to receive such  process,  to send a copy of
any such  process so  received  to Lessee at the  address of Lessee set forth in
Section  18.2  above,  or at the last  address  filed in writing by Lessee  with
Agent,  and to give prompt telefax  notice of receipt  thereof to Lessee at such
address and (y) Agent shall have no responsibility for the receipt or nonreceipt
by Lessee of such process,  nor for any performance or  nonperformance by Lessee
or Lessor or their  respective  successors  or assigns.  Lessee agrees to pay to
Agent such  compensation  as shall be agreed upon from time to time for services
hereunder. Lessee agrees that its submission to jurisdiction and its designation
of Agent set  forth  above is made for the  express  benefit  of Lessor  and its
successors,  subrogees and assigns.  Lessee agrees that a final judgment against
Lessee in any such action or proceeding shall be conclusive, and may be enforced
in other  jurisdictions  by suit on the judgment or in any other manner provided
by law, a certified  or true copy of which final  judgment  shall be  conclusive
evidence  of the fact and of the  amount of any  indebtedness  or  liability  of
Lessee therein described. Nothing in this Section 18.6 shall affect the right of
Lessor,  or its  successors,  subrogees or assigns to serve legal process in any
other manner permitted by law or affect the right of Lessor,  or its successors,
subrogees or assigns,  to bring any action or proceeding  against  Lessee or its
property in the courts of other  jurisdictions.  In the event of the transfer of
all or  substantially  all  the  assets  and  business  of  Agent  to any  other
corporation,  by consolidation,  merger, sale of assets or otherwise, such other
corporation shall be substituted  hereunder for Agent with the same effect as if
named herein in place of Agent.  Lessee  agrees that so long as this Lease shall
be in effect,  Lessee shall maintain a duly  appointed  agent for the service of
summonses  and other  legal  processes  in New York City and shall  give  Lessor
written notice prior to any change of address for such agent.

      18.6.EXPENSES.  Each party shall bear its own expenses in connection  with
the negotiation and  documentation  of this Lease and the other Lease Documents,
except  that  Lessee  shall be  solely  responsible  for the fees,  if any,  due
Newcourt  Capital  and for the  fees and  expenses  of  William  C.  Boston  and
Associates,  special FAA counsel to Lessor. In any action or proceeding  between
Lessor and Lessee to enforce the terms of this Lease, the prevailing party shall
be entitled to recover its costs and expenses, including attorneys' and experts'
fees and expenses,  incurred in connection  with such action or  proceeding.  If
there is less than a full recovery the court or arbitrator  shall  determine the
"prevailing party" for purposes of this Section.

      18.7.ARBITRATION.  Except for a failure  of Lessee to pay Rent  hereunder,
any dispute  hereunder shall be submitted to binding  arbitration in the City of
New York before an arbitrator mutually acceptable to Lessor and Lessee under the
rules of the American Arbitration  Association.  If Lessor and Lessee are unable
to agree upon a single  arbitrator,  they shall each appoint one  arbitrator and
the two so selected  shall  select a third.  All  arbitrators  shall be selected
within 30 days after  written  demand by either party.  Prior to commencing  any
arbitration proceeding the parties agree to meet in person, on not less than two
Business Days notice,  in New York and make a good faith effort to resolve their


                                       38
<PAGE>

differences.  In any such  dispute  the  prevailing  party  shall be entitled to
recover its costs and expenses,  including legal fees and expenses,  in addition
to any other recovery or award. If there is less than a full recovery, the court
or  arbitrator,  as the case may be, shall  determine the  prevailing  party for
purposes of this Section 18.8.

      18.8.SURVIVAL. The representations,  warranties, covenants, agreements and
indemnities  of Lessee and  Lessor set forth in this  Lease,  and  Lessee's  and
Lessor's   obligations   hereunder,   shall  survive  the  expiration  or  other
termination  of this  Lease to the  extent  required  for full  performance  and
satisfaction  thereof,  but in any case for two years  after  the  return of the
Aircraft.

      18.9.ENTIRE  AGREEMENT;  COUNTERPARTS.  This Lease and the  Certificate of
Acceptance  executed  pursuant hereto  constitute the entire  agreement  between
Lessor  and  Lessee  regarding  the  Aircraft  and there  are no other  prior or
contemporaneous written or oral understandings with regard to the subject matter
hereof.  At least  three  counterparts  of this Lease have been  executed by the
parties  hereto,  each of which  shall be deemed to be an  original,  but all of
which taken together shall constitute a single agreement.

      18.10.  SUCCESSORS  AND ASSIGNS.  This Lease shall be binding on and shall
inure to the  benefit of  Lessee,  Lessor and their  respective  successors  and
permitted assigns.

      18.11.  FURTHER  ASSURANCES.  Each party hereto shall,  at its  respective
expense,  promptly  and duly execute and deliver to the other party such further
documents and promptly take such further action not inconsistent  with the terms
hereof as the other party may from time to time  reasonably  request in order to
more  effectively  carry out the intent and  purpose of this Lease or to perfect
and protect the rights and, with respect to Lessor, remedies created or intended
to be created hereunder.

      18.12BANKRUPTCY,  SECTION 1110.It is the intention of the parties that the
provisions of 11 U.S.C.  Section 1110 and any  analogous  section of the Federal

possession of the Aircraft in compliance with this Agreement.  The parties agree
that this  Agreement  is  intended  to by a true  lease for  Federal  income tax

be duly  executed  by  their  authorized  officers  as of the date  first  above
written.

unless earlier terminated pursuant to the provisions of this Lease, on such date

                  (b)    [Intentionally left blank.]

                  (c)  CONDITION  OF AIRCRAFT AT DELIVERY.  Lessee  acknowledges
that on the  Commencement  Date, the Aircraft (i) was in an airworthy  condition
and   had  all   systems   functioning   in   accordance   with   manufacturer's
recommendations,  (ii) had a current  and  valid  Certificate  of  Airworthiness

and Lessee that Lessee has  examined  the  Aircraft,  that the  Aircraft and the

the Aircraft for all purposes hereof without any reservations whatsoever (except

            3.     SECURITY DEPOSIT AND OTHER PAYMENTS.

the account of Lessee of a security  deposit  (the  "Security  Deposit")  in the
total amount of [ ]* Dollars  (US$[ ]*) (the  "SECURITY  DEPOSIT  AMOUNT").  The
Security  Deposit  shall be held by Lessor during the Lease Term as security for

<PAGE>

During the Lease Term,  the Security  Deposit may be  commingled  by Lessor with
other  funds.  Interest,  if any,  earned on the Security  Deposit  shall be for
Lessor's  sole  account.  Lessor may, but shall not be  obligated  to, apply the
Security  Deposit,  in whole or in part for the  payment of any Basic Rent owing
hereunder or any other amount  owing from time to time by Lessee  hereunder,  or
utilize  the  Security  Deposit in whole or in part to perform  any of  Lessee's
obligations  hereunder  or  otherwise  remedy  any  Event  of  Default,  without
prejudice to any other remedy of Lessor. Lessee shall not attempt to subject the
Security  Deposit  to any Lien or to assign any  interest  therein to any Person
and, to the extent of its interest  therein,  Lessee  hereby  grants to Lessor a
Lien in the Security  Deposit and assigns and transfers to Lessor any and all of
Lessee's right,  title and interest therein,  as security as provided above, and
Lessor shall be entitled to the remedy of offset against and  application of the
Security  Deposit,  without any prior notice to or demand against Lessee (except
to the extent  otherwise  required by applicable  law),  all of which are hereby
waived. If Lessor uses or applies all or a portion of the Security Deposit, such
application shall not be deemed a cure of any Event of Default, until and unless
Lessee  shall have  replenished  the amount  applied  hereunder  within the time
period  provided  herein.  Lessee  shall  replenish  any  portion  or all of the
Security Deposit applied by Lessor to satisfy, in whole or in part, any Event of
Default by  depositing  with  Lessor in  immediately  available  funds an amount
sufficient to restore the Security Deposit to the Security Deposit Amount within
three (3) Business Days after Lessor's demand therefor. Within fifteen (15) days
after redelivery of the Aircraft to Lessor by Lessee,  and provided the Aircraft
is delivered in full conformity with the return  conditions set forth in SECTION
10  hereof,  and that  Lessee has paid,  in full,  all  amounts  owing by Lessee
hereunder and performed all of its obligations hereunder,  Lessor will return to
Lessee the  Security  Deposit,  without  interest,  less any amounts  applied by
Lessor and not replenished by Lessee.

to the aircraft, monthly, in advance on each Payment Date, in the amount of [ ]*
Dollars (US $[ ]*) per month ("BASIC RENT"). All payments of Basic Rent shall be
made in immediately  available  funds,  in Dollars by 2:00 p.m. New York time on
the date when due; provided,  however, that in the event that any payment should
be due on a day that is not a Business  Day,  then such payment shall be made on
the next succeeding Business Day without any penalty for late payment.

                  (c)    [Intentionally left blank.]

                  (d) SUPPLEMENTAL  RENT.  Lessee also agrees promptly to pay to
Lessor any and all  Supplemental  Rent,  as the same shall become due and owing,
and in the event of any  failure  on the part of Lessee to pay any  Supplemental
Rent,  Lessor shall have all rights,  powers and remedies provided for herein or
by law or equity or otherwise in the case of nonpayment of Basic Rent.

                  (e) MANNER OF PAYMENT.  All Basic Rent and  Supplemental  Rent

the  contrary  herein and except as otherwise  set forth in this  SECTION  3(G),
Lessee's  obligations and liabilities to pay all amounts payable hereunder shall
be absolute  and  unconditional  and shall not be affected by any  circumstance,
including, without limitation, (i) any setoff, counterclaim, recoupment, defense
or other right that Lessee may have  against  Lessor or any other Person for any
reason  whatsoever,  (ii) any defect in the title  caused  directly by an act or

<PAGE>

OR THE SUITABILITY OF THE AIRCRAFT OR ITS FITNESS FOR ANY PARTICULAR  PURPOSE OR
AS TO ITS AIRWORTHINESS. LESSOR SHALL HAVE NO LIABILITY TO LESSEE FOR ANY CLAIM,
LOSS  OR  DAMAGE  WHATSOEVER  INCLUDING,  BUT  NOT  LIMITED  TO,  INCIDENTAL  OR

without  prejudice to the  generality of the  foregoing,  neither Lessor nor any
such other Person shall be under any liability whatsoever and howsoever arising,
whether in contract or tort or both, in respect of any loss,  liability,  damage
or delay of or to or in  connection  with any of the  Aircraft  or any Person or
property whatsoever, whether on board the Aircraft or elsewhere, irrespective of
whether such loss, damage or delay shall arise (x) from the  unairworthiness  of
the  Aircraft,  or (y) from any action or  omission  of Lessor or any other such
Person (other than any action or omission that constitutes willful misconduct or
gross negligence of Lessor).

                  (b)  LESSOR'S   REPRESENTATIONS,   WARRANTIES  AND  COVENANTS.
Notwithstanding  and as the sole  exception to SECTION 5(A),  (i) FSB represents
and warrants that it is a national banking  association duly organized,  validly
existing and in good  standing  under the laws of the United  States and has all
requisite  corporate  power,  authority  and  legal  right to enter  into and to
perform its obligations  under the 1997 Trust Agreement;  (ii) Lessor represents
and  warrants  that:  (A)  unless a Default  or an Event of  Default  shall have
occurred  and be  continuing  neither  Lessor nor anyone  claiming  by, under or
through Lessor shall take any actions  inconsistent with Lessee's right of quiet
enjoyment;  (B) FSB  holds  all  material  licenses,  certificates  and  permits
necessary for the conduct of its business as now  conducted;  (C) the execution,
delivery and performance of this Lease has been duly authorized by all necessary
corporate  action  of  Lessor,  and  does not and  will  not (1)  result  in the
violation of the  provisions of the charter  documents or bylaws of Lessor as in
effect on the date  hereof,  (2)  require  stockholder  approval  or approval or
consent of any  trustee or holders of any  indebtedness  of Lessor,  except such
approvals  which  have  been  obtained  and are in full  force and  effect,  (3)
contravene  any law, rule or regulation  or any order of any  Government  Entity
binding on Lessor,  and (4) conflict  with or result in a breach of any terms or
provisions  of or  constitute  a default  under,  or result  in or  require  the
creation  or  imposition  of any Lien upon any  material  property  or assets of
Lessor under,  any  indenture,  mortgage or other  agreement or instrument as in
effect on the date  hereof  to which  Lessor is a party or by which it or any of
its property is bound,  or any  applicable  law, rule or  regulation,  judgment,
order or  decree of any  Government  Entity or court  having  jurisdiction  over
Lessor or any of its properties; and (D) this Lease constitutes the legal, valid
and binding obligation of Lessor,  enforceable against Lessor in accordance with
its  terms  except  as may be  limited  by  applicable  bankruptcy,  insolvency,
reorganization,  moratorium or other similar laws  affecting  creditors'  rights
generally  and,  to the extent  that  certain  remedies  require or may  require
enforcement by a court of equity,  by such  principles of equity  (regardless of
whether such  enforceability  is considered in a proceeding at law or in equity)
as a court having jurisdiction may impose.

                  (c) MANUFACTURER AND VENDOR WARRANTIES.  Lessor hereby assigns
to Lessee  for the  duration  of the Lease  Term (so long as no Event of Default
shall have occurred and be continuing) all assignable warranties,  if any, given
by the  Manufacturer  and other vendors with respect to the Aircraft and Engines
and  shall  obtain  Manufacturer's  consent  to  such  assignment.  Lessee  will
diligently  and  promptly  pursue  any  valid  claims  it may  have  under  such

<PAGE>

warranties and will provide notice of the same to Lessor. To the extent that any
warranty  given by the  Manufacturer  or others with  respect to the Aircraft or
Engines is not assignable or otherwise made available to Lessee,  Lessor agrees,
at its  option,  either (i) to  authorize  Lessee to take such action to enforce
such  warranty  in the  name of  Lessor  as  Lessee  sees  fit or (ii) to  exert
reasonable efforts at Lessee's request and expense (and subject to Lessee making
adequate  provision to the  satisfaction of Lessor with respect to such expense)
to enforce  any such  warranties  for the  benefit of Lessee.  Effective  on the
return of the Aircraft or the  termination of this Lease,  whichever is earlier,
Lessee hereby assigns any remaining  warranties,  and any claims thereunder,  to
Lessor or its  designee.  Upon  exercise  by Lessor  or any Party  claiming  by,
through or under Lessor of any  remedies in respect of an Event of Default,  and
at the latest,  upon expiration of the Lease Term, the benefit of all warranties
referred  to  herein  shall  immediately  revert  and be  deemed  to  have  been
reassigned by Lessee to Lessor.
      6.     MAINTENANCE; ALTERATIONS, MODIFICATIONS AND ADDITIONS.

                  (a)    MAINTENANCE.

            (i) So long as Lessor has not  committed a breach of its covenant of
      quiet enjoyment which shall have the effect of depriving Lessee of the use
      or  possession  of the  Aircraft,  during  the  Lease  Term and  until the
      Aircraft  is  returned  to  Lessor,  Lessee  shall,  at its sole  cost and
      expense,  service,  inspect,  test,  maintain,  overhaul  and  repair  the
      Aircraft, the Engines and all of the Parts in accordance with Lessee's FAA
      approved airworthiness maintenance and inspection program, a copy of which
      has been or will be  delivered  to Lessor on or prior to the  Commencement
      Date (the  "MAINTENANCE  PROGRAM")  and in  conformity  with the rules and
      regulations  of the  FAA,  (A)  so as to  keep  the  Aircraft  in as  good
      condition  (operating  and  otherwise),  appearance  and  repair  as  when
      delivered  to  Lessee  hereunder,  ordinary  wear  and tear  excepted  and
      otherwise to enable the airworthiness  certification of the Aircraft to be
      maintained in good standing at all times under  applicable  law, and to be
      and  remain  registered  in the  United  States  pursuant  to the  Federal
      Aviation Act, and (B) in the same manner and with the same care as used by
      Lessee with respect to similar  aircraft and engines  owned or operated by
      Lessee (it being the intention of the parties hereto that Lessee shall not
      discriminate against the Aircraft in respect of any maintenance  matters).
      Lessee shall be authorized  to amend its  Maintenance  Program;  provided,
      however,  that  notwithstanding  such amendment,  the Maintenance  Program
      shall,  at all times during the Lease Term, be in full conformity with the
      requirements set forth above and, further provided, that Lessee shall have
      obtained  Lessor's  prior  written  consent to any  material  amendment or
      change  in  or  to  the  Maintenance  Program.  All  service,  inspection,
      maintenance,  modification,  repair and  overhaul  shall be  performed  or
      caused to be performed by Lessee in  accordance  with all  applicable  FAA
      requirements and under the Maintenance  Program, and shall be accomplished
      in  accordance  with  all  applicable  service,  inspection,  maintenance,
      modification,  repair and overhaul manuals and bulletins  published by the
      Manufacturer or the  manufacturers  of the Engines or engines,  equipment,
      accessories  or Parts  installed  on the  Aircraft.  Without  limiting the
      generality of the foregoing or the obligations of Lessee hereunder, Lessee
      agrees  that such  maintenance  and repairs  will  include but will not be
      limited to each of the following:

                        (A)  to  perform  in  accordance  with  the  Maintenance
                  Program all routine and non-routine maintenance work;

                        (B)  to  comply  on  a   terminating   basis   with  all
                  outstanding  mandatory  orders,  airworthiness  directives and
                  instructions  issued by the FAA  affecting  the Aircraft  that
                  have an effective date for compliance prior to, or sooner than
                  one hundred  eighty  (180) days after,  the return date of the
                  Aircraft;
<PAGE>

                        (C) to incorporate in the Aircraft all service bulletins
                  of the Manufacturer, the Engine manufacturer and other vendors
                  which Lessee schedules to incorporate during the Lease Term on
                  aircraft or engines in its Boeing 737 fleet;

                        (D) to incorporate in the  maintenance  schedule for the
                  Aircraft  a  corrosion   control  program  as  recommended  by
                  Manufacturer  and the FAA and to carry out such work as may be
                  required to comply therewith,  including periodic  inspections
                  of fuel tanks,  periodic inspection and clean-up under galleys
                  and  lavatories,  the  cleaning  and  treating of all mild and
                  moderate  corrosion  and  the  correcting  of all  severe  and
                  exfoliated corrosion in accordance with the recommendations of
                  the Manufacturer; and

                        (E)  to  maintain,  in  the  English  language  (1)  the
                  Aircraft  Documentation  and (2) any  other  records,  logs or
                  other  documents,  information  or  materials  relating to the
                  service,  inspection,   testing,  maintenance,   modification,
                  overhaul and repair of the  Aircraft,  any Engine and any Part
                  which are  required by the FAA or by  applicable  law,  all of
                  which shall at all times be kept current and up-to-date, shall
                  conform  with  the  laws  of  any  Government   Entity  having
                  jurisdiction  and with  normal  practices  of  commercial  air
                  carriers,  shall  disclose  the location of any Engine or Part
                  not installed on the Airframe and shall be made  available for
                  review by Lessor on reasonable notice.

            (ii)  Lessee  shall  have  designated   persons  in  its  employment
      authorized by the FAA to perform service, inspection, modifications repair
      and  alterations  of the Aircraft,  and to return the Aircraft to Lessee's
      revenue service after such performance has been  accomplished by Lessee or
      shall have the same performed on its behalf by an FAA approved  repair and
      overhaul station in conformity with FAR 145 ("Approved Repair  Facility").
      For purposes hereof,  Lessor  acknowledges  that Lessee's  maintenance and
      repairs in  connection  with "C" checks and "D" checks (or the  equivalent
      thereof) are being performed by Tramco,  Inc. of Seattle,  Washington.  In
      the event Lessee has a third party accomplish, on a continuous basis, some
      or all of the  maintenance  requirements  under  the  Maintenance  Program
      (excluding  "A,"  preflight and transit  checks) such  maintenance by said
      third party must be accomplished in accordance with the provisions of this
      SECTION 6(A). Lessor shall be entitled and Lessee shall ensure that Lessor
      is permitted to  reasonably  visit the  facilities of any such third party
      maintenance performer to inspect the maintenance work performed on and the
      maintenance records of the Aircraft including any Engine or Part.

            (iii) Lessor may request that Lessee  accomplish  changes desired by
      Lessor  to  the  Aircraft  during  Lessee's  layup  of  the  Aircraft  for
      maintenance  under the Maintenance  Program in those  circumstances  where
      such  changes are not  required  under this  SECTION  6(A) or initiated by
      Lessee under SECTION 6(C). No such request shall be unreasonably denied by
      Lessee  provided  that no such changes  shall  require  Lessee to keep the
      Aircraft  out of service  for any  longer  period  than the  period  which
      Lessee's  maintenance  of the  Aircraft  was  scheduled  to require.  With
      respect to such requested changes,  Lessor, at its expense,  shall provide
      retrofit kits of parts and  installation  instructions  to Lessee.  Lessor
      shall,  within thirty (30) days (or such earlier period as may be required
      by any Authorized Repair Facility  performing the requested  change(s)) of

<PAGE>

      receipt of an invoice  detailing  the same,  pay all costs  thereof  which
      costs shall have been agreed upon prior to  performance  of the  requested
      changes.

            (iv) Lessee  shall give Lessor not less than thirty (30) days' prior
      written  notice of the  anticipated  date,  location and  Approved  Repair
      Facility in respect of any "C"check or "D" check (or its equivalent) to be
      performed on the Aircraft.

            (v) Repairs will be accomplished  as follows:  (A) any repair to the
      Aircraft shall be accomplished pursuant to the appropriate  manufacturer's
      repair  manual  instructions  under an FAA approved  program;  and (B) any
      material  repair to the  Aircraft  that is not covered by the  appropriate
      manufacturer's  repair  manual  instructions  shall be subject to Lessor's
      prior written approval and shall be made under an FAA approved program.

            (vi)  Notwithstanding  anything to the contrary contained herein and
      provided that the same shall not violate the terms of or conflict with any
      lease,  sublease,  credit or security  agreement to which such engine,  an
      aircraft  engine  that is not an  Engine,  but  that is  installed  on the
      Airframe, shall be maintained in accordance with this SECTION 6(A).

                  (b)    MAINTENANCE RESERVES.

                  (i) Lessee shall pay Lessor,  as Supplemental Rent for the use
            of the  Aircraft  during the Lease Term,  within  fifteen  (15) days
            following the last day of each calendar  month during the Lease Term
            and  on  the  redelivery  date,  the  following  sums  ("MAINTENANCE
            RESERVES"):  (A) with respect to each  Engine,  the sum (the "ENGINE
            RESERVE  AMOUNT") of (x) the amount  determined by  multiplying  the
            number  of Flight  Hours of  operation  of such  Engine  during  the
            immediately  preceding month (irrespective of whether such Engine is
            installed  on the  Airframe or any other  airframe)  by [ ]* Dollars
            (US$[ ]*) which  amount  shall be applied  toward  restoration  shop
            visits (the "SHOP VISIT  PORTION") and (y) the amount  determined by
            multiplying  the number of Cycles of operation of such Engine during
            the immediately preceding month (irrespective of whether such Engine
            is installed on the Airframe or any other  airframe) by [ ]* Dollars
            (US$[  ]*)  which  amount  shall  be  applied  toward  the  cost  of
            life-limited parts (the "LLP Portion"),  and (B) with respect to the
            Airframe,  the amount (the "AIRFRAME RESERVE AMOUNT")  determined by
            multiplying  the number of Flight Hours of operation of the Airframe
            during such month by [ ]* Dollars (US$[ ]*). It is the intent of the
            parties hereto that the Aircraft and Engines be operated  during the
            Lease Term at an average Flight  Hour/Cycle ratio (the "Ratio") of [
            ]* Flight  Hours to one Cycle ([ ]*:1).  During  any  calendar  year
            during the Lease Term, the total Engine Flight Hours for each Engine
            recorded in respect of the previous  twelve months shall be compared
            with the Cycles  flown for such Engine and the Ratio  computed.  The
            rate  payable  by way of  maintenance  reserve  in  respect  of each
            complete  Flight  Hour (pro rata for part  thereof)  for such Engine
            applicable  with  respect  to the Shop  Visit  Portion of the Engine
            Reserve  Amount due from Lessee after such annual Ratio  computation
            and prior to the next annual Ratio  computation shall be as provided
            in EXHIBIT G hereof for such Ratio. Any excess Maintenance  Reserves
            remaining at the expiration of the Lease Term or earlier termination
            of this Lease shall be retained by Lessor.

                  (ii) Lessee shall be entitled to  reimbursement  from the Shop
            Visit  Portion of the Engine  Reserve  Amount held for an Engine for
            Lessee's  actual costs  (without  mark-up)  incurred with respect to

<PAGE>

            heavy  maintenance of such Engine requiring a shop visit,  excluding
            any costs  associated with replacement of life limited parts and the
            cost of any repairs or maintenance required due to accidents, abuse,
            misuse,  mishandling,  faulty  maintenance,  foreign  object damage,
            elective part replacement or any insured event.  Such  reimbursement
            shall be made within ten (10)  Business Days after  presentation  to
            Lessor of appropriate written evidence of such expenses (which shall
            include  a copy  of an  invoice  from  an  FAA-approved  maintenance
            facility  indicating  that the  maintenance  has been  completed and
            identifying  those engine  maintenance  tasks  accomplished  and the
            labor  and  material  breakdown  thereof,  and a  receipt  from  the
            maintenance  facility for payment of the  invoice,  or at least such
            amount  thereof  as shall  exceed  the  portion  of the  Maintenance
            Reserves  available  to Lessee  hereunder);  PROVIDED,  that (A) the
            amount  reimbursed  to Lessee  shall not  exceed  the  amount of the
            Maintenance  Reserves paid by Lessee (and not previously  disbursed)
            allocable to the Shop Visit Portion of the Engine Reserve Amount for
            the Engine  requiring a shop visit, and (B) in no event shall Lessee
            be entitled to reimbursement  for any expenses related to removal or
            installation  of any Engine for maintenance or any other shipping or
            transportation  expenses. To the extent that any amount reimbursable
            hereunder  has not been paid by Lessee,  such  amount  shall be paid
            directly to the  maintenance  facility which  performed the services
            for which reimbursement is sought.

                  (iii) Lessee shall be entitled to  reimbursement  from the LLP
            Portion of the Engine  Reserve  Amount (i) for the full  replacement
            cost of life  limited  parts  having a  remaining  life of up to and
            including  one  thousand  two  hundred  fifty  (1250)  Cycles.  Upon
            reimbursement  of such replacement  costs,  Lessee shall deliver the
            removed  life limited  parts to Lessor at the overhaul  facility and
            cause  title  thereto to vest in Lessor  free and clear of all Liens
            other than Lessor Liens, and (ii) of such portion of the replacement
            cost of life limited parts having a remaining  life in excess of one
            thousand  two hundred  fifty  (1250)  Cycles as  corresponds  to the
            utilized  (non-remaining)  portion of the life of such life  limited
            parts as compared to the total life  thereof  when new, as expressed
            in  Cycles.  With  respect  to such  life  limited  parts  having  a
            remaining  life in excess of one thousand  two hundred  fifty (1250)
            Cycles,  title to such life limited parts shall be deemed to vest in
            Lessee upon  installation  of replacement  parts on an Engine.  Such
            reimbursement  shall be made  within  ten (10)  Business  Days after
            presentation to Lessor of appropriate written evidence of such costs
            (which  shall  include  a copy of an  invoice  from an  FAA-approved
            supplier of such life limited parts, identifying those purchased and
            receipt of payment  therefor or at least payment for such portion as
            shall exceed the LLP Portion of the Engine Reserve Amount  available
            to Lessee  hereunder and of the Approved Repair Facility  indicating
            that such life  limited  parts  have been  installed  on an  Engine;
            provided,  that (A) the amount reimbursed to Lessee shall not exceed
            the  amount of the  Maintenance  Reserves  paid by  Lessee  (and not
            previously  disbursed)  allocable  to the LLP  Portion of the Engine
            Reserve Amount for the Engine  requiring a shop visit, and (B) in no
            event shall  Lessee be entitled to  reimbursement  for any  expenses
            related to removal,  shipping  or  transportation  expenses.  To the
            extent that any amount  reimbursable  hereunder has not been paid by
            Lessee,  such amount  shall be paid  directly to the supplier of the
            life limited part(s) for which reimbursement is sought.

                  (iv)  Lessee  shall  be  entitled  to  reimbursement  from the
            Airframe  Reserve Amount for the costs  incurred  pursuant to a full
            structural and systems "D" check (or its equivalent) to occur during
            the Lease  Term.  Such  reimbursement  shall be made within ten (10)
            Business Days after  presentation  to Lessor of appropriate  written

<PAGE>

            evidence of such expenses  (which shall include a copy of an invoice
            from an FAA-approved  maintenance  facility  indicating that the "D"
            check (or its equivalent)  has been completed and identifying  those
            maintenance tasks  accomplished and the labor and material breakdown
            thereof,  and a receipt from the maintenance facility for payment of
            the  invoice,  or at least such amount  thereof as shall  exceed the
            portion of the  Maintenance  Reserves  available  to Lessee from the
            Airframe Reserve Amount  hereunder);  provided,  that (A) the amount
            reimbursed to Lessee shall not exceed the amount of the  Maintenance
            Reserves paid by Lessee (and not previously  disbursed) allocable to
            the  Airframe  Reserve  Amount,  and (B) in no event shall Lessee be
            entitled  to  reimbursement  for any  expenses  related to  removal,
            shipping or transportation  expenses.  To the extent that any amount
            reimbursable  hereunder  has not been paid by  Lessee,  such  amount
            shall be paid directly to the  maintenance  facility which performed
            the "D" check for which reimbursement is sought.

                  (v) In  respect of any  maintenance  work to be  performed  or
            replacement of life limited parts for which  reimbursement  from the
            applicable  portion of the  Maintenance  Reserves will be requested,
            Lessee,  prior to the performance of such maintenance or replacement
            of life limited parts,  shall deliver to Lessor a detailed workscope
            to be  performed  with an  estimate  of all costs to be  incurred in
            connection with such maintenance  and/or replacement of life limited
            parts, including,  without limitation,  the estimated cost of labor,
            materials and parts for which  reimbursement is available under this
            SECTION 6(B).

                  (vi) Provided that no breach by Lessor of Lessor's covenant of
            quiet  enjoyment  depriving  Lessee of its use or  possession of the
            Aircraft  has  occurred  and is  continuing,  nothing  herein  shall
            modify,  limit or otherwise  affect Lessee's  obligation to maintain
            and repair the Aircraft in  accordance  with the terms of this Lease
            and, except as specifically provided herein, any and all maintenance
            and repairs on or to the Aircraft shall be at Lessee's sole cost and
            expense.

                  (c) REPLACEMENT OF PARTS.  Lessee, at its own cost and expense
(except as otherwise expressly provided herein), will promptly replace all Parts
that may from time to time be  incorporated  or  installed in or attached to the
Aircraft  or any Engine and 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,  except as otherwise provided
in SECTION 6(E). In addition, Lessee may, at its own cost and expense, remove in
the ordinary course of maintenance,  service,  repair,  overhaul or testing, any
Parts, whether or not worn out, lost, stolen,  destroyed,  seized,  confiscated,
damaged  beyond  repair or  permanently  rendered  unfit for use;  provided that
Lessee,  except as otherwise provided in SECTION 6(E), will, at its own cost and
expense, replace such Parts as promptly as possible. All replacement Parts shall
(i) be free and clear of all  Liens  (except  Permitted  Liens,  as  hereinafter
defined,  and except for pooling arrangements to the extent permitted by SECTION
6(D)),  (ii) be in  airworthy  and  good  operating  condition  and of at  least
equivalent model and  modification  status and have a value and utility at least
equal to, the Parts replaced (assuming such replaced Parts were in the condition
and  repair  required  to be  maintained  by the  terms  hereof)  and  (iii)  if
applicable,  have a current "serviceable tag" of the manufacturer or maintenance
facility  providing  such items to Lessee,  indicating  that such Parts are new,
serviceable  or  overhauled.  All Parts at any time removed from the Aircraft or
any Engine shall remain 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 the  Aircraft or such Engine and that meet the
requirements  for  replacement  Parts  specified  above.  Immediately  upon  any
replacement  Part  becoming  incorporated  or  installed  in or  attached to the
Aircraft or any Engine as above provided,  without further act, (i) title to the

<PAGE>

replaced Part shall  thereupon vest in Lessee,  free and clear of Lessor's Liens
and all  rights of  Lessor,  and  shall no  longer  be  deemed a Part  hereunder
provided,  however,  that  in the  case  of  any  Part  that  is  replaced  by a
replacement Part subject to a pooling  arrangement,  title to such replaced Part
shall not vest in Lessee  until  Lessee  has  complied  with the  provisions  of
SECTION 6(D), (ii) title to such  replacement Part shall vest in Lessor and such
replacement Part shall thereupon become subject to this Lease (subject only to a
pooling  arrangement  to the extent  permitted  by SECTION  6(D)) and (iii) such
replacement  Part shall be deemed  part of the  Aircraft  or such Engine for all
purposes  hereof  to the same  extent as the Parts  originally  incorporated  or
installed in or attached to the Aircraft or such Engine.

                  (i)  there is not  available  to Lessee at the time and in the
            place  that an engine or part is  required  to be  installed  on the
            Aircraft,  a  Replacement  Engine  or,  as the  case  may  be,  Part
            complying  with the  requirements  of  SECTION  6(C);  (ii) it would
            result  in an  unreasonable  disruption  of  the  operation  of  the
            Aircraft  and/or the business of Lessee to ground the Aircraft until
            an Engine or Part, as the case may be,  complying  with SECTION 6(C)
            becomes  available for  installation  on the Aircraft;  and (iii) as
            soon as practicable  after  installation of the same on the Aircraft
            but,  in any  event,  no  later  than  the  date of the  next  major
            maintenance  check (except as such time may be extended  pursuant to
            SECTION  8(B)),  Lessee removes any such engine or part and replaces
            it with an  Engine  or  Part,  as the case  may be,  complying  with
            SECTION 6(C).

                  (d) POOLING OF PARTS.  Any Part (other than  Engines)  removed
from the  Aircraft as provided in SECTION  6(C) may be  subjected by Lessee to a
normal pooling arrangement customary in the airline industry entered into in the
ordinary  course  of  Lessee's   business  with  financially  and  operationally
responsible  air  carriers;  provided no Default or Event of Default  shall have
occurred and be continuing  and further  provided that the Part  replacing  such
removed Part shall be  incorporated  or installed in or attached to the Aircraft
in  accordance  with  SECTION 6(C) after the removal of such  removed  Part.  In
addition,  any replacement Part when incorporated or installed in or attached to
the Aircraft in accordance  with SECTION 6(C) may be owned by a financially  and
operationally   responsible  air  carrier  subject  to  such  a  normal  pooling
arrangement;  provided  that  Lessee,  at its  expense,  either (i) causes  such
replacement Part to become subject to this Lease in accordance with SECTION 6(C)
by Lessee  acquiring  title  thereto for the benefit of Lessor free and clear of
all Liens other than Permitted Liens or (ii) replaces such  replacement  Part by
incorporating   or  installing  in  or  attaching  to  the  Aircraft  a  further
replacement  Part  owned by  Lessee  free  and  clear of all  Liens  other  than
Permitted Liens and by causing such further  replacement  Part to become subject
hereto in accordance with SECTION 6(C).

                  (e) ALTERATIONS,  MODIFICATIONS AND ADDITIONS. EXCEPT FOR SUCH
ALTERATIONS AND MODIFICATIONS TO THE AIRCRAFT AND THE ENGINES AS MAY BE REQUIRED
FROM TIME TO TIME TO MEET THE STANDARDS OF THE FAA OR OTHER GOVERNMENTAL  ENTITY
HAVING  JURISDICTION  AND AS  REQUIRED  TO CONFORM TO  MANUFACTURERS'  MANDATORY
SERVICE BULLETINS, LESSEE SHALL MAKE NO ALTERATIONS,  MODIFICATIONS OR ADDITIONS
TO THE  AIRCRAFT  OR ANY ENGINE  WITHOUT  THE PRIOR  WRITTEN  CONSENT OF LESSOR.
Lessee, at its own expense,  will make such alterations and modifications to the
Aircraft  and the  Engines  as may be  required  from  time to time to meet  the
standards of the FAA or other  Governmental  Entity having  jurisdiction  and as
required to conform to  Manufacturers'  mandatory service  bulletins,  and shall
notify  Lessor of the nature and  schedule  for making such  changes  and,  upon
submission  of the Monthly  Report for the month during which  completion of the
same shall have occurred,  of completion  thereof.  Unless expressly required by
the  FAA  or  Manufacturer's   mandatory  service   bulletins,   no  alteration,
modification  or addition shall diminish the value or utility of the Aircraft or

<PAGE>

such Engine, or impair the condition or airworthiness  thereof, below the value,
utility,   condition  and  airworthiness   thereof  immediately  prior  to  such
alteration,  modification or addition  (assuming the Aircraft or such Engine was
then of the value or utility and in the condition and airworthiness  required to
be maintained  by the terms of this Lease),  it being  understood  that any such
alteration,  modification or addition that adversely affects  interchangeability
of Parts shall be deemed to diminish the value of the  Aircraft.  Promptly  upon
request therefor, Lessee shall provide to Lessor copies of all drawings and data
with respect to any proposed  alteration,  modification or addition not mandated
by the FAA.  Lessor may impose as a condition  to its consent to all or any part
of such proposed alteration,  modification or addition that, prior to the return
of the  Aircraft to Lessor in  accordance  with  SECTION  10,  such  alteration,
modification or addition be removed and the Aircraft  returned,  all at Lessee's
expense,  to the condition it was in prior to such  alteration,  modification or
addition,  and  otherwise as required by SECTION 10. All parts  incorporated  or
installed  in or attached or added to the  Aircraft or such Engine as the result
of such alteration,  modification or addition shall, without further act, become
subject to this Lease.  Notwithstanding  the foregoing  sentence of this SECTION
6(E),  so long as no  Default or Event of Default  shall  have  occurred  and be
continuing,  Lessee  may  remove  any  Part;  provided  that (i) such Part is in
addition to, and not in replacement of or substitution  for, any Part originally
incorporated  or  installed  in or attached to the Aircraft or any Engine at the
time  of  delivery  thereof   hereunder  or  any  Part  in  replacement  of,  or
substitution  for  any  such  Part,  (ii)  such  Part  is  not  required  to  be
incorporated or installed in or attached or added to the Aircraft or such Engine
pursuant  to the terms of this  SECTION  6(E) and (iii) such Part can be removed
from the Aircraft or such Engine  without  diminishing  or impairing  the value,
utility,  condition or  airworthiness  required to be maintained by the terms of
this Lease that the Aircraft or such Engine would have had at such time had such
removal not occurred.  Upon the removal by Lessee of any Part as above provided,
title thereto shall,  without further act, vest in Lessee and such Part shall no
longer be deemed part of the  Aircraft or such Engine from which it was removed.
Any Part removed by Lessee in any manner other than as above  provided  prior to
the return of the Aircraft or such Engine to Lessor  hereunder  shall remain the
property of Lessor.

            Notwithstanding  anything  herein to the  contrary,  Lessee shall be
permitted  to install and remove,  at its sole cost and  expense,  new  galleys,
seats,  video and  entertainment  systems and  telephones,  provided that Lessee
shall store any galleys and video, entertainment and telephone systems currently
installed on the Aircraft and removed  therefrom by Lessee, in a safe manner and
at its sole cost and expense and,  provided,  except as otherwise agreed between
Lessee and Lessor, that any such equipment installed upon the Aircraft by Lessee
is removed by Lessee at its sole cost and  expense and Lessee  shall  return the
Aircraft with the Lessor's equipment reinstalled thereon or, if lost or damaged,
with the equivalent  thereof,  satisfactory to Lessor, and further provided that
Lessee  shall  repair at its sole cost and expense  and to  Lessor's  reasonable
satisfaction,  any damage to the Aircraft  caused by or in connection  with such
installation and removal.


            7.     TITLE AND REGISTRATION; LIENS; POSSESSION.

                  (a) TITLE AND  REGISTRATION.  Lessee  acknowledges  and agrees
that as between Lessee and Lessor, title shall at all times be and remain vested
solely and  exclusively  in Lessor,  and  Lessee  shall have no right,  title or
interest  in the  Aircraft  except  the right to use the  Aircraft  as  provided
herein. The Aircraft has been duly registered, and shall at all times during the
Lease Term remain duly  registered,  in the name of Lessor under the laws of the
United States, except as otherwise required by the Federal Aviation Act. Lessee,
at its sole cost and expense, shall from time to time do or cause to be done any
and all acts and things then required by law (including the Geneva Convention on
the  International  Recognition  of Rights in  Aircraft,  if  applicable)  or by
practice,  custom  or  understanding  or as Lessor  may  reasonably  request  to
protect, preserve and perfect Lessor's, rights and interests in the Aircraft and
this Lease in the United States or in any other  jurisdiction into or over which
Lessee may operate the Aircraft or to which Lessee is subject.  Without limiting
the  generality  of the  foregoing,  if at any time any filing or  recording  is

<PAGE>

necessary  or  advisable  to perfect,  protect  and/or  preserve  the rights and
interests of Lessor in the Aircraft (including Engines and Parts) or this Lease,
Lessee  shall,  at its  own  cost  and  expense,  cause  this  Lease,  financing
statements  with  respect  hereto,  and  any  and all  additional  documents  or
instruments which shall be executed pursuant to the terms hereof or thereof,  so
far as permitted  by  applicable  law, to be kept,  filed and recorded and to be
reexecuted,  refiled  and  rerecorded  at all times in the  appropriate  offices
pursuant or in relation to the  applicable  laws and  regulations  of the United
States,  and shall furnish to Lessor an opinion of counsel and/or other evidence
satisfactory to Lessor of such  registrations,  recordation and filings required
hereunder.

                  (b) LIENS.  Lessee  will not  directly or  indirectly  create,
incur,  assume or suffer to exist any Lien on or with respect to the Airframe or
any  Engine,  title  thereto  or any Part or  interest  therein or in this Lease
except (i) the respective  rights of Lessor and Lessee as herein provided,  (ii)
the rights of others under  agreements or arrangements  to the extent  expressly
permitted by the terms of SECTION 6(D), (iii) Lessor Liens, (iv) Liens for Taxes
either not yet due or being  contested  in good faith  (and,  in respect of such
contest,  for the payment of which  adequate  reserves  have been  provided)  by
appropriate  proceedings  diligently  pursued so long as such proceedings do not
involve any material  danger of the sale,  forfeiture or loss of the Airframe or
any  Engine  or Part or  interest  therein  and (v)  materialmen's,  mechanics',
workmen's,  repairmen's,  employees' or other like Liens arising in the ordinary
course of business for amounts the payment of which is either not yet delinquent
or is being  contested in good faith (and, in respect of such  contest,  for the
payment of which adequate  reserves or other adequate  provisions for payment by
way of security or otherwise,  have been  provided) by  appropriate  proceedings
diligently  pursued so long as such proceedings do not involve any danger of the
sale,  forfeiture  or loss of the  Airframe  or any  Engine or Part or  interest
therein  (each of the Liens  referred  to in  clauses  (i) to (v)  being  herein
referred to as  "PERMITTED  Liens").  Lessee will notify,  as soon as reasonably
practicable,  Lessor and shall promptly, at its sole cost and expense, take such
action as may be necessary to discharge any such Lien not excepted  above if the
same shall arise at any time. Lessee hereby further agrees that no mechanics' or
similar Lien for any labor,  services or materials  supplied directly by Lessee,
shall attach to or  otherwise  affect the  Aircraft,  any Engine or any Part and
Lessee hereby irrevocably waives disclaims and releases any such Lien.

                  (c) OPERATION,  QUIET  ENJOYMENT.  Lessee shall not operate or
locate the  Aircraft,  or suffer the Aircraft to be operated or located,  (i) in
violation of any applicable law or the Aircraft's  certificate of airworthiness,
(ii) other than on regularly scheduled or charter commercial  passenger or cargo
flights between any points in the Americas except (inclusive of any landings) in
Cuba except if otherwise  required to ferry the  Aircraft to an Approved  Repair
Facility,  (iii) in any area excluded from coverage by any insurance required by
the  terms  of  SECTION  9, or  (iv) in any  recognized  or  threatened  area of
hostility  without Lessor's written consent and unless fully covered to Lessor's
satisfaction by war risk, confiscation and hijacking insurance. Lessee shall not
use the Aircraft for testing or for  training of flight  crewmembers  other than
Lessee's own crewmembers.  Except as otherwise provided herein, Lessee shall pay
all costs  incurred in the operation of the Aircraft  during the Lease Term, for
profit or otherwise, including the costs of flight crews, cabin personnel, fuel,
oil, lubricants,  maintenance,  insurance, storage, landing and navigation fees,
airport charges, passenger service and any and all other expenses of any kind or
nature,  directly  or  indirectly,  in  connection  with or  related to the use,
movement and operation of the Aircraft.  Provided no Default or Event of Default
shall occur and be  continuing,  Lessor  shall not take or cause or permit to be
taken any action  inconsistent  with  Lessee's  right of quiet  enjoyment of, or
otherwise in any way interfere with or interrupt the continuing  use,  operation
and possession of the Aircraft, the Airframe or any Engine by Lessee.

                  (d) POSSESSION.  EXCEPT AS OTHERWISE  PROVIDED IN THIS SECTION
7(D),  LESSEE  SHALL HAVE NO RIGHT  WHATSOEVER  TO SUBLEASE  THE AIRCRAFT OR ANY
ENGINE TO ANY  PERSON  WITHOUT  HAVING  OBTAINED  THE PRIOR  WRITTEN  CONSENT OF

<PAGE>

LESSOR.  Lessor agrees that it will not  unreasonably  withhold its consent to a
proposed  sublease by Lessee. In addition and  notwithstanding  anything in this
Lease to the  contrary,  Lessee will not in any manner  without  Lessor's  prior
written consent deliver,  transfer or relinquish possession of the Aircraft, the
Airframe  or any  Engine or  install  any  Engine,  or permit  any  Engine to be
installed, on any airframe other than the Airframe;  provided,  that, so long as
no Default or Event of Default  shall have  occurred and be  continuing,  and so
long as the action to be taken shall not deprive  Lessor of its  interest in the
Aircraft, Lessee may, from time to time, take any of the following actions:

                  (i) deliver  possession  of the  Airframe or any Engine to the
            manufacturer  thereof or to any organization  for testing,  service,
            repair,  maintenance  or overhaul work on the Airframe or any Engine
            or any Part of any thereof or for alterations or modifications in or
            additions to such  Airframe or any Engine to the extent  required or
            permitted by the terms of SECTION 6(E); or

                  (ii) to the extent permitted by this SECTION 7(D), subject any
            appliances,  parts or other  equipment  owned by Lessor and  removed
            from the Airframe or any Engine to any pooling arrangement  referred
            to in SECTION 6(D) of the Lease; or

                  (iii)  install the Engines on any airframe  owned or leased by
            Lessee;  provided  that,  no lien shall attach to any such Engine by
            virtue of or in connection  with such  installation,  and the owner,
            lessor, or any party having a security interest in any such airframe
            grants  reciprocal  rights to Lessor;  and  further  provided  that,
            Lessee  shall  maintain  any  and  all  insurance   required  to  be
            maintained upon or in respect of the Engines  hereunder at all times
            during  the  Lease  Term  and  until  redelivery  of the same in the
            condition required in SECTION 10 hereof, or

                  (iv) transfer  possession of the Airframe or any Engine to any
            Government  Entity of the United  States  pursuant to a sublease,  a
            copy of which shall be promptly  furnished to Lessor,  provided that
            such sublease  shall (A) not extend beyond the end of the Lease Term
            and (B) Lessee  shall have  delivered to Lessor  signed  copies of a
            notice of  assignment  of such sublease in favor of Lessor under the
            Assignment  of Claims  Act of 1940,  as amended  (31 U.S.C.  Section
            3727,  41  U.S.C.  Section  15)  or  any  superseding  or  successor
            provisions thereto, and in compliance with the applicable provisions
            of 32 C.F.R.  Section  7-103.8  and 41  C.F.R.  Section  1-30.7,  or
            superseding or successor laws and regulations, and Lessor may at any
            time when a Default or Event of Default shall have occurred and then
            be  continuing,  file such sublease and an original and three copies
            of such  notice  of  assignment  with  the  proper  contracting  and
            disbursing   officers  and  otherwise  comply  with  all  applicable
            provisions  of 32  C.F.R.  Section  7-103.8  or any  superseding  or
            successor provisions thereto.

            Any "wet lease" or other  similar  arrangement  under  which  Lessee
maintains  operational  control of, and  continues  to  maintain  and insure the
Aircraft,  for a term not exceeding twelve (12) months (including all extensions
and renewals),  shall not constitute a sublease,  transfer or  relinquishment of
possession  for  purposes of this  SECTION  7(D).  Lessee  shall  notify  Lessor
concurrently with entering into any "wet lease" with a term,  including renewals
of more than six (6) months.

            No  sublease,  transfer  or  relinquishment  of  possession  of  the
Airframe  or any  Engine  permitted  under  this  SECTION  7(D) shall in any way
discharge or diminish any of Lessee's  obligations  hereunder,  or  constitute a

<PAGE>

waiver of any of Lessor's  rights and remedies  hereunder.  Notwithstanding  any
sublease,  transfer or relinquishment of possession permitted under this SECTION
7(D),  Lessee shall remain primarily liable hereunder for the performance of all
of the  terms of this  Lease  to the same  extent  as if any  such  transfer  or
relinquishment of possession had not occurred.

                  (e) IDENTIFICATION  PLATES. Lessee shall at all times maintain
in a prominent  position in the cockpit of the  Airframe  and on each Engine the
identification  plates  installed  thereon or  attached  thereto.  Lessee  shall
promptly replace any such  identification  plate that becomes  illegible,  lost,
damaged or destroyed for any reason.

                  (f) REPORTING REQUIREMENTS. Commencing with a report furnished
fifteen (15) days after the end of the calendar month of the Commencement  Date,
Lessee will furnish to Lessor a Monthly  Report in the form  attached  hereto as
EXHIBIT F, which  report will  include  (i) the  hours/cycles  operated  for the
Airframe and each of the Engines (and their location by airframe). On at least a
quarterly  basis  Lessee's  report  will also  contain  a list of those  service
bulletins, ADs and engineering modifications  incorporated on the Aircraft. Each
Monthly Report will be furnished  within fifteen (15) days after the end of each
calendar month,  except that the Monthly Report pertaining to the last month (or
any portion  thereof) of the Lease Term will be  furnished to Lessor on the last
day of the Lease Term.

                  (g)  INSPECTIONS.  During the Lease Term Lessee shall  furnish
Lessor such information concerning the location, condition, use and operation of
the  Aircraft  as Lessor  may  reasonably  request.  Lessee  shall  give  Lessor
reasonable prior notice of the anticipated date of any major maintenance checks,
in order to enable Lessor to inspect the Aircraft (should it choose to do so) at
the time and place such major checks occur. Lessor shall be entitled to have its
technical  representatives  present  during  any major  maintenance  checks.  On
reasonable notice,  Lessor and/or its authorized agents or representatives shall
have the right to inspect the Aircraft and  Aircraft  documentation  (whether in
connection with scheduled  major  maintenance  checks or otherwise)  and/or make
copies of the Aircraft  documentation;  provided,  that such  inspections do not
unreasonably  disrupt  Lessee's  commercial   operations  or  operation  of  the
Aircraft.  Lessor shall have no duty to make any such  inspection  and shall not
incur any  liability  or  obligation  by reason of making or not making any such
inspection or by reason of any reports it receives or any reviews it may make of
the Aircraft records.


            8. LOSS, DESTRUCTION, REQUISITION, ETC. During the Lease Term except
as otherwise  expressly  provided  herein,  Lessee shall bear the entire risk of
loss of or damage to the Aircraft. Accordingly:

                  (a)  EVENT OF LOSS  WITH  RESPECT  TO THE  AIRCRAFT.  Upon the
occurrence  of an Event of Loss  with  respect  to the  Aircraft,  Lessee  shall
forthwith (and, in any event,  within seven (7) days after such occurrence) give
Lessor  written  notice of such Event of Loss. On or before the earlier to occur
of (x) the actual receipt by Lessee of any insurance proceeds in respect of such
Event of Loss and (y) the one  hundred  twentieth  (120th) day after the date of
such Event of Loss,  but in no case  later than the last day of the Lease  Term,
Lessee shall pay to Lessor in immediately  available  funds the Stipulated  Loss
Value,  whereupon (l) the obligation of Lessee to pay Basic Rent with respect to
the  Aircraft  for any  period  commencing  after  the date of  payment  of such
Stipulated Loss Value shall terminate;  provided that Lessee shall remain liable
for all  payments  of Basic  Rent due on or before  the date of such  payment of
Stipulated  Loss  Value,  (2) the Lease  Term  shall end and (3)  Lessor,  after
compliance  by Lessee  with all of its other  obligations  hereunder,  including
without  limitation  payment of Supplemental Rent then due, will cause Lessor to
transfer to Lessee, without recourse or warranty, title to the Aircraft free and
clear of Lessor Liens.

                  (b)  EVENT  OF  LOSS  WITH  RESPECT  TO AN  ENGINE.  Upon  the
occurrence of an Event of Loss with respect to an Engine only, Lessee shall give

<PAGE>

Lessor prompt written notice thereof and shall,  as soon as practical but in any
event within one hundred twenty (120) days after the occurrence of such Event of
Loss,  convey or cause to be conveyed to Lessor,  as replacement  for the Engine
with respect to which such Event of Loss occurred, title to a Replacement Engine
free and clear of all Liens,  other than  Permitted  Liens,  and having a value,
utility,  mod  status at least  equal  to,  and of the same or  improved  model,
service bulletin status, and maintenance  status (I.E. total time,  hours/cycles
remaining until next inspection,  overhaul or scheduled removal) and in at least
as good  operating  condition as, the Engine with respect to which such Event of
Loss occurred, assuming such Engine was of the value, utility and remaining life
and in the condition and repair required by the terms hereof  immediately  prior
to the  occurrence  of such  Event of Loss.  Prior to or at the time of any such
conveyance,  Lessee, at its own expense, will promptly (i) furnish Lessor with a
bill of sale, in form and substance satisfactory to Lessor, with respect to such
Replacement  Engine;  (ii)  cause a  supplement  hereto,  in form and  substance
reasonably  satisfactory to Lessor,  subjecting such Replacement  Engine to this
Lease,  to be duly  executed  by Lessee,  and  recorded  pursuant to the Federal
Aviation  Act;  (iii)  furnish  Lessor  with  such  evidence  of  title  to such
Replacement Engine and of compliance with the insurance  provisions of SECTION 9
with respect to such Replacement Engine as Lessor may reasonably  request;  (iv)
furnish  Lessor with an opinion of Lessee's  counsel to the effect that title to
such  Replacement  Engine has been duly conveyed to Lessor free and clear of all
Liens,  encumbrances  and rights of others (except  Permitted Liens) and is duly
leased  hereunder;  (v)  furnish  Lessor  with a  certificate  signed  by a duly
authorized  financial  officer or executive of Lessee  certifying  that Lessee's
representations  and warranties set forth in SECTION 11 are true and accurate on
and as of  said  date  as  though  made on and as of said  date  and  that  upon
consummation  of such  replacement,  no Default  or Event of Default  will exist
hereunder;  (vi) furnish Lessor with such documents and evidence with respect to
Lessee as Lessor may reasonably  request in order to establish the  consummation
of the  transactions  contemplated  by this  SECTION  8(B),  the  taking  of all
corporate proceedings in connection therewith and compliance with the conditions
set forth in this SECTION 8(B), in each case in form and substance  satisfactory
to such party;  (vii)  furnish  Lessor with a certificate  of a duly  authorized
officer of Lessee to the effect  that no Event of Default  has  occurred  and is
continuing;  and (viii)  furnish Lessor with Uniform  Commercial  Code financing
statements covering such Replacement Engine. Upon full compliance by Lessee with
the terms of this  subparagraph  (b),  such Engine shall no longer be subject to
the terms of this Lease and Lessor will  transfer to Lessee  title to the Engine
with respect to which the Event of Loss occurred,  without  recourse or warranty
(except  that the  Engine  is free and clear of Lessor  Liens)  and shall  cause
Lessor to execute and deliver to Lessee an instrument  releasing the Engine from
the Lease. For all purposes hereof, each such Replacement Engine shall be deemed
part of the property  leased  hereunder,  shall be deemed an "Engine" as defined
herein  and shall be deemed  part of the  Aircraft  as was the  Engine  replaced
thereby.  No Event of Loss  covered by this  SECTION  8(B)  shall  result in any
reduction  in Basic  Rent.  Notwithstanding  the  foregoing,  if,  as of the one
hundred  twentieth  (120th) day following  the  occurrence of the Event of Loss,
Lessee shall not have furnished a Replacement  Engine as required  hereunder and
conforming to the  requirements  set forth above,  at Lessor's option (i) Lessor
shall extend the time period within which Lessee may perform its  obligations to
furnish a Replacement  Engine hereunder,  or, (ii) Lessee shall forthwith pay to
Lessor,  an amount  equal to the  Engine  Loss  Value and upon  receipt  of such
payment Lessor shall,  as soon as practicable  but in any event prior to the end
of Lease Term, lease to Lessee  hereunder,  a Replacement  Engine complying with
the conditions of this SECTION 8(B).  Notwithstanding  the provisions of SECTION
6(C) hereof any engine installed by Lessee on the Aircraft following an Event of
Loss to an Engine may remain thereon until  replaced by a Replacement  Engine as
hereinafter provided.

                  (c) APPLICATION OF PAYMENTS FROM GOVERNMENTAL Authorities. Any
payments (other than insurance proceeds the application of which is provided for
in SECTION 9) received  at any time by Lessor or by Lessee  from any  Government
Entity or other  Person  with  respect  to an Event of Loss  resulting  from the
condemnation,  confiscation,  theft or seizure of, or requisition of title to or
use of,
<PAGE>

 the  Aircraft  or any  Engine,  other than a  requisition  for use by a
Government  Entity of the United States not  constituting an Event of Loss, will
be applied as follows:

                  (i) if such payments are received with respect to the Airframe
            or the Airframe and one or more Engines or engines  installed on the
            Airframe,  such payments  shall be paid to or retained by Lessor and
            applied in reduction of Lessee's  obligation  to pay the  Stipulated
            Loss Value,  if not already  paid by Lessee,  or, if already paid by
            Lessee,  shall be paid to or  retained  by  Lessee  and  applied  to
            reimburse  Lessee for its payment of such Stipulated Loss Value, and
            the balance,  if any, of such payment remaining  thereafter shall be
            distributed to Lessee; and

                  (ii) if such  payments are received with respect to an Engine,
            such payments  shall be held by the Lessor until (A)  replacement of
            the  Engine  by Lessee by a  Replacement  Engine at which  time said
            payments  shall be paid to Lessee;  (B) if Lessor shall have elected
            to provide a  Replacement  Engine as provided  in SECTION  8(B) said
            payments shall be applied in reduction of Lessee's obligation to pay
            the Engine Loss Value, if not already paid by Lessee;  or if already
            paid by  Lessee,  shall be paid to Lessee and  applied to  reimburse
            Lessee for its  payment of such  Engine  Loss  Value;  and,  (C) the
            balance, if any, of such payment remaining thereafter to Lessee.

                  (d) REQUISITION  FOR USE OF THE AIRCRAFT.  In the event of the
requisition for use of the Aircraft by a Government  Entity of the United States
and one or  more  related  Engines  or  engines  during  the  Lease  Term  under
circumstances  not  constituting an Event of Loss,  Lessee shall promptly notify
Lessor of such  requisition.  All of Lessee's  obligations under this Lease with
respect to such Aircraft  including,  but not limited to Lessee's  obligation to
pay Rent,  shall  continue  to the same  extent as if such  requisition  had not
occurred.  In the event of a breach of  Lessee's  obligations  pursuant  to this
SECTION  8(D),  all payments  received by Lessor or Lessee from such  Government
Entity for the use of such  Aircraft  and Engines or engines  shall be paid over
to, or  retained  by,  Lessor to the extent of Lessee's  obligations  under this
Lease.

                  (e) QUIET  ENJOYMENT.  Notwithstanding  the provisions of this
SECTION 8, if (i) Lessee has been  deprived  of both use and  possession  of the
Aircraft  or any  Engine or Part  thereof  solely  as a result of the  breach by
Lessor of its covenant of quiet enjoyment set forth herein and (ii) Lessee shall
have provided  Lessor written notice to the effect that Lessee has been deprived
of such use and  possession and that Lessee intends to cancel its insurance with
respect to the  Aircraft or any such Engine or Part on a date  specified in such
notice  (which date shall not be earlier than thirty (30) days after the date of
Lessor's  receipt of such notice),  then,  from and after the date so specified,
but only during the period that Lessee shall continue to be deprived of both use
and possession of the Aircraft or such Engine or Part (the "Suspension Period"),
(A) Lessor shall bear the entire risk of loss or damage thereof (other than loss
or damage caused by an act or omission of Lessee during the Suspension  Period),
and (B) Lessee shall be relieved of its obligation to maintain insurance, as set
forth in SECTION 9 hereof,  with  respect  thereto.  In the event of an Event of
Loss of the Aircraft during any such period, the Lease shall terminate and, upon
such  termination  (i) the Aircraft shall be deemed to have been  redelivered to
Lessor in the condition required as of the date on which such deprivation of use
or  possession  first  occurred,  (ii)  Lessee  shall be relieved of all further
obligations  hereunder  except  such as are  expressly  stated  to  survive  the
termination of this Lease and (iii) Lessor shall, return the Security Deposit to
Lessor as provided  in SECTION 3. In the event of an Event of Loss with  respect
to an Engine not involving an Event of Loss with respect to the Airframe  during
any  such  period,  Lessor  shall  at its  sole  cost  and  expense,  as soon as
practicable  but in any event  within  120 days  after the date of such Event of
Loss,  provide a Replacement  Engine  complying with all terms of this Lease and
meeting all conditions  otherwise imposed hereunder on Lessee in the event of an

<PAGE>

Event of Loss with respect to an Engine.  Immediately upon Lessee being restored
use and  possession  of the Aircraft or any Engine or Part with respect to which
the risk of loss shall have passed from Lessee to Lessor in accordance with this
SECTION 8(E),  the entire risk of loss thereof shall again be borne by Lessee in
accordance with the terms of this Lease.

            9.  INSURANCE.  Except as otherwise set forth in SECTION 8(E) hereof
in respect of any Suspension Period, Lessee, at its sole cost and expense, shall
maintain  or cause to be  maintained  throughout  the  Lease  Term and until the
return of the Aircraft to Lessor in such  condition as is required under SECTION
10 hereof with insurers of recognized  responsibility  and good repute and under
policies reasonably  satisfactory to Lessor all such insurance as is required to
be procured  and  maintained  pursuant to this SECTION 9. Such  insurance  shall
include:

                  (a)   LIABILITY.   Public   liability   (including,    without
limitation,  aircraft  third-party,  baggage,  cargo,  contractual and passenger
legal liability  including war risks),  property damage liability insurance with

(including   products   liability   insurance)   with   insurers  of  recognized
responsibility and good repute specializing in aviation insurance in the leading
international  markets,  in form  satisfactory to Lessor and in amounts at least
equal to the greater of (a) [ ]* Dollars (US$[ ]*) per occurrence  subject to no
deductible  except  deductibles as to baggage and cargo that are standard in the
airline  industry in respect of carriers  operating  in the  countries  in which
Lessee  operates  and (b)  the  amount  of  such  insurance  carried  by  Lessee
applicable to other aircraft of similar type in Lessee's fleet.

                  (b)  OTHER  INSURANCE.   (i)  all-risk   (including,   without
limitation,  ground and flight)  aircraft  hull  insurance  with  respect to the
Aircraft in an amount  which shall not at any time while the Aircraft is subject
to this Lease be less than Stipulated Loss Value;

                  (i) hull war-risk insurance with respect to the Aircraft in an
            amount which shall not be less than the Stipulated Loss Value of the
            Aircraft;  provided,  further,  however,  that such insurance  shall
            include but not be limited to, coverage  against (1) war,  invasion,
            acts of foreign  enemies,  hostilities  (whether  war be declared or
            not), civil war, rebellion, revolution,  insurrection,  martial law,
            military or usurped power or attempts at  usurpation  of power,  (2)
            strikes, riots, civil commotions or labor disturbances,  (3) any act
            of one or more persons,  whether or not agents of a sovereign power,
            for  political or terrorist  purposes and whether the loss or damage
            resulting therefrom is accidental or intentional,  (4) any malicious
            act or act of sabotage, (5) confiscation,  nationalization, seizure,
            restraint,  detention,  appropriation,  requisition  of title or use
            (other than requisition for use by a Government Entity of the United
            States)  by or under the  order of any  government  (whether  civil,
            military  or de facto)  or any  public  or local  authority  and (6)
            hijacking or any unlawful seizure or wrongful exercise of control of
            the  Aircraft  or crew in  flight  (including  any  attempt  at such
            seizure  or  control)  made by any  person or  persons  on board the
            Aircraft acting without the consent of Lessee;

                  (ii) all-risk  (including,  without limitation,  fire, transit
            and extended coverage) insurance, and war-risk insurance of the type
            specified in SECTION 9(B)(II) to the extent available,  with respect
            to each Engine when not  installed  on the Airframe in an amount not
            less than the Engine Loss Value of such Engine;

                  (iii) such  other  insurance  as Lessee  carries in respect of
            other similar aircraft in its fleet.
<PAGE>

      Notwithstanding  anything in the foregoing to the  contrary,  no insurance
shall have a deductible in excess of $[ ]*.

                  and each  other  Additional  Insured  in such  policies,  such
                  insurance  shall not be  invalidated by any action or inaction
                  of Lessee or any other  Person and shall  insure  Lessor's and
                  the Additional Insureds'  interests,  regardless of any breach

                  declarations or conditions contained in such policies;

                        (D) shall  contain a waiver by the  insurers  of (i) all

                  cancellation,  lapse, alteration,  termination or cancellation
                  shall  not be  effective  as to the  Additional  Insureds  for

                  from any of the Additional Insureds; and

                  (iii) All amounts payable under policies carried in accordance
            with this SECTION 9 shall be paid in immediately  available,  freely
            transferable Dollars in the United States. In the case of a lease or
            contract with the United States or any Government  Entity thereof in
            respect of the Aircraft,  a valid  agreement duly assigned to Lessor
            to indemnify  Lessee  against the same risks that Lessee is required
            under  SECTION 9(B) to insure  against by the United  States or such
            Government Entity in an amount at least equal to the Stipulated Loss
            Value shall be  considered  adequate  insurance  with respect to the
            Aircraft to the extent of the risks and in the amounts  that are the
            subject of any such agreement to indemnify.

                  (iv) All insurance maintained pursuant to this SECTION 9 shall
            be (A) maintained  with recognized  aircraft and aviation  insurance
            companies  in  the  United  States  or  international  markets  that
            normally  participate in aviation  insurance or (B) supported by 99%
            reinsurance  issued by  recognized  aircraft and aviation  insurance
            companies in the international  markets that normally participate in
            international aviation insurance. Any such reinsurance shall be with

<PAGE>

            insurers,  in form and in amounts reasonably  satisfactory to Lessor
            and  shall  be  subject  to  "cut  through"  endorsements  or  other
            endorsements  or  agreements  satisfactory  in form and substance to
            Lessor which shall provide that all payments under such  reinsurance
            in  respect  of  losses  shall be paid (x) in the case of  insurance
            maintained  pursuant  to  SECTION  9(A)  hereof,  to the  applicable
            Additional  Insured  or (y)  in the  case  of  insurance  maintained
            pursuant  to  SECTION  9(B)  hereof,  to KGAL as sole  "loss  payee"
            (except  as  provided  in SECTION  9(C)(II)(B))  and not to any such
            primary insurance company.

                  (d)  APPLICATION  OF  INSURANCE.  All  insurance  or indemnity
payments  received  as the  result  of the  occurrence  of an Event of Loss with
respect to the Airframe or an Engine will be applied as follows:

                  (i)  if  such  payments  are  received  with  respect  to  the
            Airframe,  the Engines or engines installed  thereon,  such payments
            shall be applied in the following  order of priority:  (A) to Lessor
            in the  amount  required  to be paid by Lessee  pursuant  to SECTION
            8(A),  which  amount  shall be  applied  in  reduction  of  Lessee's
            obligation  to pay such amount if not already  paid by Lessee or, to
            the extent such amount has been paid by Lessee to Lessor,  to Lessee
            to  reimburse  Lessee for its payment  thereof and (B) to Lessee the
            balance, if any, of such payment; and

                  (ii) if such  payments are received with respect to an Engine,
            such payments shall be held by the insurer until (A)  replacement of
            the  Engine  by Lessee by a  Replacement  Engine at which  time said
            payments  shall be paid to Lessee;  (B) if Lessor shall have elected
            to provide a  Replacement  Engine as provided  in SECTION  8(B) said
            payments  shall be paid to  Lessor to be  applied  in  reduction  of
            Lessee's  obligation  to pay the Engine Loss  Value,  if not already
            paid by  Lessee,  or if  already  paid by  Lessee,  shall be paid to
            Lessee and  applied  to  reimburse  Lessee  for its  payment of such
            Engine Loss Value;  and (C) the balance of such payment,  if any, to
            Lessee.

            The insurance  payments with respect to any property damage loss not
constituting any Event of Loss with respect to the Airframe or an Engine will be
paid to Lessor and  applied by Lessor in payment  (or to  reimburse  Lessee) for
repairs to or  replacement  of property in accordance  with the terms of SECTION
6(C) against  evidence  satisfactory to Lessor that such repairs and replacement
have been made, or, if such repairs or replacement have already been paid for by
Lessee, to reimburse Lessee therefor, and any balance remaining after compliance
with such Section with respect to such loss shall be paid to Lessee.  Any amount
referred  to in the  preceding  sentence  or in  paragraph  (i) or  (ii) of this
SECTION  9(D) that is  payable  to Lessee  shall not be paid to Lessee if at the
time of such payment an Event of Default or Default  shall have  occurred and be
continuing,  but shall be held by Lessor as  security  for and may be applied to
the  obligations of Lessee under this Lease and, at such time as there shall not
be continuing  any such Default or Event of Default,  such amount not previously
so  applied  shall be paid to Lessee.  Notwithstanding  the  provisions  of this
paragraph, payments in respect of partial losses of less than [ ]* Dollars (US$[
]*) shall be paid  directly to Lessee to be applied by Lessee toward the cost of
repair or replacement of such property in conformity herewith.

                  (e) REPORTS.  On or before the Commencement  Date, Lessee will
furnish  or cause  to be  furnished  to  Lessor  a  report  signed  by a firm of
independent  aircraft insurance  brokers,  appointed by Lessee and acceptable to
Lessor,  stating the opinion of such firm that the  insurance  then  carried and
maintained on the Aircraft  complies  with the terms  hereof.  Lessee will cause
such firm to advise Lessor and each other Additional Insured in writing promptly
of any  default in the payment of any  premium,  of any other act or omission on
the part of Lessee of which such firm has  knowledge  that might  invalidate  or
render unenforceable,  in whole or in part, any insurance on the Aircraft and of

<PAGE>

each claim made by Lessee in respect  of the  Aircraft.  Lessee  will also cause
such firm to advise Lessor and each other Additional Insured in writing at least
thirty (30) days prior to the expiration or termination of any insurance carried
and maintained on the Aircraft pursuant to this SECTION 9.

                  (f) FAILURE TO INSURE.  In the event that Lessee shall fail to
maintain or cause to be maintained insurance as herein provided,  Lessor may, at
its option,  but without  liability to Lessee for failure to do so, provide such
insurance  and, in such event,  Lessee  shall,  upon written  demand,  reimburse
Lessor for the cost thereof as Supplemental Rent. At any time while such failure
is  continuing,  Lessor may require the Aircraft to remain at any airport or (as
the case may be) proceed to and remain at any airport  within the United  States
as   designated   by  Lessor,   until  such  failure  is  remedied  to  Lessor's
satisfaction.

                  (g)  ADDITIONAL  INSURANCE.  Nothing  contained  in this Lease
shall  prevent  Lessor or Lessee,  each at its own expense and for its exclusive
benefit,  from  carrying  insurance  covering  the  Aircraft  in addition to the
insurance  required  under  this  SECTION  9  (any  such  additional  insurance,
"ADDITIONAL INSURANCE"); provided, however, that such Additional Insurance shall
be excess and  non-contributory  to the  insurance  required to be procured  and
maintained by Lessee hereunder.  The insurance  payments for any property damage
loss  covered  by  Additional  Insurance  shall be paid  directly  to the  party
carrying such Additional Insurance.  Lessee may carry hull all risks or hull war
and allied perils on the Aircraft in excess of the Stipulated Loss Value only to
the extent such excess  insurance which would be payable to Lessee  following an
Event of Loss does not prejudice the insurances  required herein or the recovery
by Lessor  thereunder.  Lessee agrees that it will not create or permit to exist
any Liens (other than Lessor Liens) over the insurances required  hereunder,  or
its interest therein, except as constituted by this Lease.

                  (h)  NOTICE OF CLAIMS.  Lessee  shall  give  Lessor  notice in
writing  of any claim or  request  for  payment  of an amount in excess of $[ ]*
under any physical damage insurance  policy required to be maintained  hereunder
promptly  (but in any event within five (5) days) of the filing of such claim or
request for payment.

                  (i)  STIPULATED  LOSS VALUE.  At any time  following the first
anniversary  of the  Commencement  Date,  Lessee may  propose a revision  to the
Stipulated Loss Value Schedule set forth as Schedule I hereof, and, upon receipt
of any such proposal,  Lessor and Lessee shall negotiate in good faith a revised
Schedule I of this Lease.


      10. RETURN OF AIRCRAFT.  The  provisions of this SECTION 10 shall apply to
any return of the Aircraft to Lessor upon termination of this Lease  (including,
without limitation,  such return resulting from an Event of Default);  provided,
that if this Lease is  terminated  pursuant  to SECTION 14 and the  Aircraft  is
repossessed  by  Lessor,  any  action  that is  required  to be taken by  Lessee
pursuant to this SECTION 10 prior to the return of the  Aircraft  shall be taken
immediately after the return of such Aircraft.

                  (a) REDELIVERY UPON TERMINATION. On the date of termination of
this Lease, except as otherwise provided pursuant to SECTION 8(E) hereof, Lessee
shall at its sole cost and  expense,  return  the  Aircraft  to  Lessor,  at the
Lessee's  facilities  in  Colorado  Springs,  Colorado  or at  those  of its FAA
approved  maintenance provider performing the pre-redelivery "C" check (provided
that if this Lease shall be  terminated as a result of a default by Lessee under
the  Lease  the  Aircraft  shall be  returned  to a point in the  United  States
reasonably  requested  by  Lessor).  At the time of  return of the  Aircraft  to
Lessor,  Lessor  and  Lessee  shall  execute  a  Return  Acceptance  Receipt  in
substantially the form of EXHIBIT C hereto.

            the provisions of the Manufacturer's  Maintenance Planning Document,
            Corrosion   Prevention   Manual  or  737  Structural  Repair  Manual
            criteria,  in each  case,  without  discrimination  as  between  the
            Aircraft and Lessee's other Boeing 737-300 aircraft.

                  (ix) Except as otherwise permitted in SECTION 6(E) hereto, the
            Aircraft shall be in the same  configuration  and condition with all

<PAGE>

            equipment  installed  therein  as that in  which  the  Aircraft  was
            delivered  to Lessee by Lessor  under  this  Lease,  excepting  only
            ordinary  wear and  tear,  replacements  and  substitute  parts  and
            equipment as may have been properly made by Lessee  pursuant to this
            Lease.

                  (x) The  Aircraft  will be free  of  fuel,  oil and  hydraulic
            leaks.  Any  temporary  fuel leak repairs will have been replaced by
            permanent repairs.

                  (xi) The Aircraft fluid reservoirs  (including oil, hydraulic,
            water and waste tanks) will be serviced to full in  accordance  with
            Manufacturer's  instructions,  and each fuel tank  shall  contain at
            least  the  quantity  of  fuel as was  contained  therein  when  the
            Aircraft was delivered to Lessee on the  Commencement  Date;  or, in
            the  case of any  deficiency,  Lessee  shall  pay  Lessor  for  such
            deficiency at Lessor's then current cost of fuel.

                  (xii) No special or unique  Manufacturer,  Engine manufacturer
            or FAA  inspection or check  requirements  which are specific to the
            Aircraft or Engines and have which arisen  during the Lease Term (as
            opposed to all  aircraft or engines of their  types) will exist with
            respect to the Airframe, Engines and Aircraft equipment,  components
            and systems.

                  (xiii) All repairs,  modifications and alterations made to the

<PAGE>

                  (d) CONDITION OF CONTROLLED COMPONENTS. Each life-limited part
or  component  and  aircraft  hour and/or  cycle  controlled  components  of the
Aircraft and of each Engine at the time of  redelivery of the Aircraft to Lessor
shall have remaining at least 3,000 hours and/or 3,000 cycles, whichever is more
limiting, between scheduled removals for overhaul, testing, or disassembly.  All
components  controlled  on a calendar  basis  shall have  remaining  at least 12
months  before  scheduled  removal for testing or overhaul.  Such  hour/cycle or
calendar controlled  components are defined as those components controlled under
the Maintenance Program.  However, if the component or part has a check interval
limit that is less than the above stated  hours,  cycles or calendar  time limit
requirement, the check interval limit shall prevail.

                  (e)  CONDITION  OF  ENGINES.  (i) Each  Engine  at the time of
return to Lessor  whether  or not  installed  on the  Airframe  shall  have been

            on each  Engine  and its  modules  in  accordance  with  the  Engine
            manufacturer's    maintenance    manual,    with   Lessor   or   its
            representatives entitled to be present. Lessee will provide evidence
            to Lessor's  satisfaction  that such  inspection does not reveal any
            condition  which  would  cause  the  Engine  or  any  module  to  be
            unserviceable,   beyond  serviceable  limits,  or  serviceable  with
            limitations  under the  Engine  manufacturer's  maintenance  manual.
            Lessee  will  correct  any  discrepancies  in  accordance  with  the
            guidelines  set  out  by  the  Engine   manufacturer  which  may  be
            discovered during such inspection.

                  (iii) Each Engine shall have an exhaust gas temperature margin
            remaining of 15 degrees or higher and shall, at a minimum,  meet all
            the requirements of the maximum power assurance run criteria for CFM
            56-3B2 engines.

                  (iv) The Aircraft shall be capable of certificated, full rated
            performance  without  limitations  throughout  the entire  operating
            envelope as defined in the  Manufacturer's  flight manual applicable
            to the Aircraft which performance compliance will be demonstrated at
            the time of the  demonstration  flight  referred to in SECTION 10(H)
            and/or by on-wing static  inspection and testing of the  powerplants
            (engines,   nacelles  and   accessories)   in  accordance  with  the
            maintenance manual applicable to such Engine, at Lessor's option.

                  (v)  The  auxiliary  power  unit  or  units  installed  in the
            Aircraft at the time of return to Lessor shall have no more than 500
            Flight  Hours since the last  overhaul  as per the Garret  Workscope
            definition,  shall be in good  operating  condition and shall have a
            borescope   inspection  and   "on-condition"   check   performed  in
            accordance with the Maintenance Program. Satisfactory evidence shall
            be provided to Lessor reflecting the correction of any discrepancies
            found during such inspection or such check, as the case may be.
<PAGE>

                  (f) GROUND INSPECTION BY LESSOR.  The Aircraft  (including the
Aircraft  documentation and other related documents to be returned  therewith as
provided  in  SECTION  10(L))  shall be made  available  to  Lessor  for  ground
inspection  by  Lessor  at  Lessee's  facilities  or those  of its FAA  approved
maintenance  provider during the pre-redelivery "C" check. Such inspection shall
commence  not less than  seven  working  days prior to the date of return of the
Aircraft to Lessor.  Lessee shall remove the Aircraft from scheduled service and
open the areas of the  Aircraft as required to perform the  necessary  checks as
contemplated  by this Lease and shall allow Lessor to accomplish  its inspection
in order to determine that the Aircraft  (including the Aircraft  documentation)
and other related documents are in the condition set forth in SECTION 10. During
such  pre-redelivery  "C"  check,  Lessor's  personnel  shall  have the right to
reasonably  request that adjacent  additional panels or areas be opened in order
to allow further  inspection by Lessor personnel.  Lessee shall promptly correct
any  discrepancies  from the condition  required by the provisions of SECTION 10
that are  observed  during such  inspection  and are  communicated  by Lessor to
Lessee.

                  (g) OPERATIONAL GROUND CHECK. Promptly after completion of any
corrections  required  under SECTION  10(F),  Lessee shall conduct an operations
ground check  (including  an engine  power  assurance  run and a flight  control
operational and rigging check) in accordance with the Manufacturer's maintenance
manual  criteria  for the purpose of  demonstrating  that each of the  following
systems meet applicable  manufacturer's criteria: (i) full fuel tank leak check;
(ii) altimeter calibration; (iii) ATC transponder system operational check; (iv)
audible ignition check (both systems);  (v) pilot and static systems check; (vi)
hydraulic system internal leak check; and (vii) brake wear check. Promptly after
the operational  ground check,  Lessee shall repair any discrepancies  resulting
therefrom.

                  (h)  DEMONSTRATION  FLIGHT.  Promptly after  completion of any
corrections required under SECTIONS 10(F) and 10(G), the Aircraft shall be flown
by  Lessee,   using   qualified   flight  test   personnel  and  the  applicable
Manufacturer's  test flight document,  for  approximately one and one-half hours
for the purpose of  demonstrating  to Lessor the  satisfactory  operation of the
Aircraft and its equipment.  During such test flight, command, care, custody and
control of the Aircraft  shall at all times remain with Lessee.  Representatives
of Lessor  may  participate  in such  flight as  observers.  A  qualified  pilot
designated  by Lessor  shall occupy the cockpit  observer's  seat as an observer
during such demonstration  flight. Upon completion of such demonstration flight,
the  representatives  of Lessee and Lessor  participating in such  demonstration
shall agree in writing upon any  discrepancies  in the  Aircraft  required to be
corrected  by Lessee in order to comply with the  provisions  of this SECTION 10
and  Lessee  shall  promptly  correct  any  such  discrepancies.  Subsequent  to
corrections of such  discrepancies,  Lessor shall inspect and technically accept
the Aircraft for redelivery  subject to the  requirements  of this SECTION 10(H)
and SECTIONS  10(I) and (J) below.  If any of the  discrepancies  referred to in
SECTIONS 10(F) and 10(G) or this SECTION 10(H) continue to persist,  Lessor may,
at its  option,  agree to  accept  redelivery  of the  Aircraft  and  apply  the
procedure set forth in SECTION 10(J) for such discrepancies.

                  (i) FERRY FLIGHT. Upon completion of the demonstration  flight
and after  Lessee has  corrected  discrepancies  as  required to comply with the
provisions  of this SECTION 10, or Lessor has agreed to apply the  procedure set
forth  in  SECTION  10(J),  the  Aircraft  shall be  ferried  by  Lessee  to the
redelivery  point  set forth in  SECTION  10(A)  hereof.  Lessee  shall,  at the
Lessor's  request,  ferry the Aircraft  from the  redelivery  point set forth in
SECTION  10(A)  hereof to any other  location  within the 48  contiguous  United
States of America, as may be designated by the Lessor, at the Lessor's expense.

                  (j) DEFERRED DISCREPANCY  CORRECTION.  Any discrepancies found
during the ground inspection, operational ground check, demonstration flight and
ferry  flight  provided  for  in  SECTIONS  10(F),   10(G),   10(H)  and  10(i),
respectively,  that were not corrected by Lessee prior to return of the Aircraft
to  Lessor  may be  corrected  by  Lessor or its  designee  after  return of the
Aircraft and Lessee shall reimburse  Lessor for the expenses  incurred by Lessor
or its designee for accomplishing such discrepancy corrections. Lessee shall pay
Lessor  for  such  expenses  incurred  within  thirty  (30)  days of the date of
Lessor's invoice therefor.
<PAGE>

                  (k) FLIGHT COST.  All flights  pursuant to SECTIONS  10(H) and
10(I) shall be made at Lessee's expense and Lessee shall pay or reimburse Lessor
for any costs associated with such flights including,  but not limited to, costs
for  fuel,  oil,  airport  fees,   insurance,   takeoff/landing   fees,   airway
communication fees and ground handling fees.

                  (l) AIRCRAFT  DOCUMENTATION.  Lessee shall return to Lessor at
the time the  Aircraft  is  returned  to  Lessor,  all of the  Aircraft  records
documents,  manuals and data  provided to Lessee by Lessor prior to, on or after
the  Commencement  Date,  updated and  maintained by Lessee  through the date of
return of the  Aircraft.  In addition,  Lessee shall also provide  Lessor at the
time the  Aircraft is returned to Lessor with all  records,  documents,  manuals
authorizations,  drawings and data, in each case in the English  language,  that
were  developed  or caused to be  developed  by Lessee  and/or  required  by the
appropriate  governmental agency having  jurisdiction  updated and maintained by
Lessee for the Aircraft  through the date of return of such  Aircraft.  Any such
Aircraft  documentation  not already owned by Lessor,  when  delivered to Lessor
pursuant to this SECTION 10(L),  shall thereupon  become the property of Lessor.
In the event Lessor requires copies of any of such Aircraft  documentation prior
to the return of the Aircraft to Lessor to enable  Lessor to plan or  accomplish
modifications,   recertification,   sale,  lease  or  other  disposition  of  or
utilization  of the  Aircraft  upon such return,  Lessee  shall,  promptly  upon
receipt of each such Lessor  request,  provide to Lessor a reasonable  number of
copies of such Aircraft documentation  requested by Lessor at Lessor's sole cost
and expense.

                  (m)  SERVICE   BULLETIN  KITS.  All  vendor  and  Manufacturer
supplied  mandatory  service  bulletin kits delivered to Lessee for the Aircraft
but not installed  therein  shall be returned with the Aircraft,  as part of the
Aircraft  at the time of the  return  of the  Aircraft,  and  shall be loaded by
Lessee on board the  Aircraft as cargo.  Title to such kits shall pass to Lessor
concurrently with the delivery of the Aircraft to Lessor.

                  (n)  NON-U.S.  MANUFACTURED  ITEMS.  Lessee  shall  provide to
Lessor at the time of the return of the Aircraft a complete list,  describing by
Part  number  and  name,  of  all  non-United  States  manufactured   equipment,
components  and parts,  if any,  installed on such Aircraft by Lessee during the
Lease Term.  Such list shall include  quantity,  the  acquisition  price and the
manufacturer's name and country in respect of each such item.

                  (o) LESSEE'S CONTINUING OBLIGATIONS.  In the event that Lessee
does  not  return  the  Aircraft  to  Lessor  upon  termination  of  this  Lease
(including,  without  limitation,  any  termination  resulting  from an Event of
Default by Lessee) and in the  condition  required  herein for any  reason,  the
obligations of Lessee under this Lease shall continue;  provided,  however, that
such failure to return the Aircraft to Lessor in such condition shall not be the
result  of a breach  by  Lessor of its  covenant  of quiet  enjoyment  which has
resulted in Lessee  having been  deprived of use and  possession of the Aircraft
immediately  prior to such  termination,  in which  case the  Aircraft  shall be
returned in its then condition  provided that,  immediately prior to such breach
by Lessor of its covenant of quiet  enjoyment  such Aircraft  shall have been in
such  condition  as to meet the  requirements  of  SECTION 8 hereof but for such
breach.  Such  continuation  of Lessee's  obligations  shall not be considered a
renewal of the terms of this Lease or of Lessee's rights to use the Aircraft, an
extension  of the Lease  Term or a waiver of any  Default or Event of Default or
an
<PAGE>

 right of Lessor hereunder. Until such time as the Aircraft is redelivered to
Lessor as required  herein,  Lessee  agrees,  during the first  thirty (30) days
following  the  termination  hereof,  to pay  Basic  Rent with  interest  at the
Post-Default  Rate and thereafter to pay twice the amount of Basic Rent for each
day from such thirtieth (30th) day after the termination hereof until redelivery
of the Aircraft in the  condition  required  hereunder  (the monthly  Basic Rent
payable  being  prorated  based on the actual  number of days in the  applicable
month).

            11.    REPRESENTATIONS,   WARRANTIES   AND  COVENANTS  OF  LESSEE.
Lessee represents and warrants to, and covenants with Lessor as follows:

                  (a)  Lessee  (i) has been  duly  incorporated  and is  validly
existing  as a  corporation  in good  standing  under  the laws of the  State of
Delaware, (ii) has full corporate power and authority and legal right to own its
properties  and to carry on its business as presently  conducted  and to perform
its  obligations  under  this  Lease,  (iii)  is the  holder  of an air  carrier
certificate   duly  issued  pursuant  to  the  Federal  Aviation  Act  and  such
certificate is in full force and effect,  and (iv) holds all material  licenses,
certificates  and permits from all Government  Entities of the United States and
other  jurisdictions  necessary for the conduct of its business as now conducted
and for the operation of the Aircraft.

                  (b) The execution,  delivery and performance of this Lease has
been duly authorized by all necessary  corporate action of Lessee,  and does not
and will not (i)  result  in the  violation  of the  provisions  of the  charter
documents  or bylaws of Lessee  as in effect on the date  hereof,  (ii)  require
stockholder  approval  or  approval  or consent of any trustee or holders of any
indebtedness  of Lessee,  except such approvals which have been obtained and are
in full force and effect,  (iii)  contravene  any law, rule or regulation or any
order of any  Government  Entity  binding on Lessee,  or (iv)  conflict  with or
result in a breach of any terms or provisions of or constitute a default  under,
or result in or require the creation or imposition of any Lien upon any material
property or assets of Lessee under,  any material  indenture,  mortgage or other
agreement  or  instrument  as in effect on the date hereof to which  Lessee is a
party or by which it or any of its  property is bound,  or any  applicable  law,
rule or regulation,  judgment, order or decree of any Government Entity or court
having jurisdiction over Lessee or any of its properties.

                  (c) No authorization,  approval, consent, license or order of,
or  registration  with,  or the  giving of notice to, or the taking of any other
action  in  respect  of,  any  Government  Entity  is  required  for  the  valid
authorization,  execution,  delivery and  performance by Lessee of this Lease or
the  consummation of any of the  transactions  contemplated  hereby,  except (i)
approvals,  authorizations,  consents, licenses,  certificates and orders of the
FAA and any other regulatory  authority having  jurisdiction with respect to the
ownership,  use and operation of the Aircraft and the transactions  contemplated
hereby,  all of which  have been (or on the  Delivery  Date will have been) duly
obtained  and are (or will on the  Delivery  Date be) in full force and  effect,
(ii) the filing of this Lease or other  necessary  documentation  with the civil
aviation  authority of each country  (other than the United States) in which the
Aircraft may be operated or located  which  filings  have been made,  or will be
made as to each such country prior to such Aircraft being operated or located in
such country and (iii) any normal periodic and other reporting  requirements and
renewals  and  extensions  of any of the  foregoing,  in each case to the extent
required to be given or obtained only after the Delivery Date.

                  (d) Except for (i) the filing and  recording  pursuant  to the
Federal Aviation Act of this Lease,  (ii) the filing of duly executed  financing
statements naming Lessee as debtor and Lessor as secured party (and continuation
statements  with respect to such  financing  statements)  with the  Secretary of
State of the State of  Colorado  and,  if  applicable,  the  appropriate  filing
authority in El Paso County  Colorado  and (iii) the  retention by Lessor of the
original  counterpart  of the  Lease  to the  extent,  if any,  that  the  Lease
constitutes  chattel  paper (as such term is defined in the  Uniform  Commercial
Code as in effect in any applicable jurisdiction),  no further action, including
any filing or recording of any document  (including  any financing  statement in

<PAGE>

respect thereof under Article 9 of the Uniform Commercial Code of any applicable
jurisdiction),  is necessary in order to establish and perfect Lessor's title to
the  Aircraft  as  against  Lessee  and  any  third  parties  in any  applicable
jurisdictions in the United States.

                  (e) This  Lease  constitutes  the  legal,  valid  and  binding
obligation of Lessee,  enforceable  against Lessee in accordance  with its terms
except as may be limited by applicable bankruptcy,  insolvency,  reorganization,
moratorium or other similar laws affecting  creditors'  rights generally and, to
the extent that certain remedies  require or may require  enforcement by a court
of  equity,   by  such   principles  of  equity   (regardless  of  whether  such
enforceability  is  considered  in a proceeding  at law or in equity) as a court
having jurisdiction may impose.

                  (f) There are no suits or proceedings  pending or, to Lessee's
knowledge,  threatened in any court or before any  Government  Entity against or
affecting Lessee that would, if adversely  determined,  (i) prevent or adversely
affect  Lessee's  ability to perform  its  obligations  under this Lease or (ii)
materially  adversely affect the financial condition or operations of Lessee and
its consolidated subsidiaries, taken as a whole.

                  (g)  The  chief  executive  office  (as  such  term is used in
Article 9 of the Uniform  Commercial Code) of Lessee and the office where Lessee
will keep its corporate  records  concerning  the Aircraft is located in El Paso
County,  Colorado.  Lessee  will  notify  Lessor  thirty (30) days in advance of
moving either such office to another location.

                  (h)    [Intentionally left blank.]

                  (i) Neither  Lessee nor any of its  property  has any immunity
from  jurisdiction  of any court  located in the United States or from any legal
process in the United  States  (whether  through  service or notice,  attachment
prior to judgment, attachment in aid of execution, execution or otherwise).

                  (j)  There  is no Tax,  levy,  impost,  deduction,  charge  or
withholding  imposed by the State of Colorado or any Taxing Authority thereof or
therein either (i) on or by virtue of the execution or delivery of this Lease or
(ii) on any payment made or to be made by Lessee under this Lease.

                  (k) The  obligations  of Lessee under this Lease rank at least
pari passu in right of payment with all other  unsecured  obligations of Lessee,
with the exception of such obligations as are mandatorily preferred by law.

                  (l) Lessee will promptly give notice to Lessor upon  obtaining
actual knowledge of any Default or Event of Default; and

                  (m)  Lessee  acknowledges  that in the  event  Lessee  files a
petition or otherwise  seeks relief under the Bankruptcy  Code or an involuntary
petition is filed  against  Lessee,  it is the  intention  of Lessor that Lessor
shall be entitled to the benefits of Title 11 U.S.C. ss. 1110 and any similar or
analogous  provisions of any successor  statute ("Section 1110") with respect to
the  Aircraft  and this  Lease,  and Lessee  agrees that it shall not oppose 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  Section  1110  unless  Lessee  shall  have  complied  with  the
requirements  of Section  1110 to be  fulfilled  in order to  entitle  Lessee to
continue use and possession of the Aircraft hereunder.

                  (n)  Without  having  obtained  the prior  written  consent of
Lessor,  Lessee will not  consolidate  with or merge into, sell or lease, in one
transaction or a series of transactions,  all or substantially all of its assets
to  another  corporation  or other  entity  unless  such  other  corporation  or
subsidiary  thereof  is engaged in the  airline  business,  the net worth of the

<PAGE>

corporation  resulting from such merger or consolidation or corporation or other
entity to which  such sale or lease is made  would be at least  equal to the net
worth of Lessee at the date hereof, such corporation or other entity assumes all
of  Lessee's  obligations  under  this Lease in a manner  and by  documents  and
agreements  satisfactory to Lessor in its sole  discretion,  such corporation or
other entity immediately subsequent to such merger, consolidation, lease or sale
is not in  default  hereunder  and if Lessor  receives  an  opinion  of  counsel
satisfactory to it as to such assumption and documentation.

                  (o) Lessee agrees to furnish to Lessor as soon as practicable,
but in no event  later  than (i) sixty  (60)  days  after the end of each of the
first  three  quarterly  fiscal  periods  in  each  fiscal  year  of  Lessee,  a
consolidated  balance sheet of Lessee and its subsidiaries  prepared by it as of
the close of such period,  together with the related consolidated  statements of
income and of surplus and  statements of changes in financial  position for such
period  (this  requirement  may be  satisfied by delivery to Lessor of a copy of
Lessee's  Form 10-Q),  (ii) one hundred and twenty (120) days after the close of
each  fiscal  year of Lessee,  a  consolidated  balance  sheet of Lessee and its
subsidiaries  as of the close of such  fiscal  year,  together  with the related
consolidated  statements  of income and of surplus and  statements of changes in
financial  position for such fiscal year,  as  certified by  independent  public
accountants,  including their accompanying opinion letter related thereto, (iii)
with each such  financial  statement,  a certificate  of Lessee signed by a duly
authorized  financial  officer  of  Lessee,  to the  effect  that the signer has
reviewed  the  relevant  terms of this Lease and has made,  or caused to be made
under his  supervision,  a review of the  transactions  and  condition of Lessee
during the accounting  period covered by the financial  statements and that such
review has not disclosed the existence during such accounting  period,  nor does
the signer have  knowledge of the existence as at the date of such  certificate,
of any condition or event that constitutes a Default or Event of Default, or, if
any such condition or event existed or exists,  specifying the nature and period
of existence  thereof and what action  Lessee has taken or is taking or proposes
to take with respect thereto and (iv) from time to time, such other  information
as Lessor may reasonably request; provided that such other information is either
in the public  domain or is  provided  to lessors  of  aircraft  to Lessee or to
creditors of Lessee.

                  (p) Lessee shall,  within fifteen (15) days of the end of each
and every  calendar  month  during the Lease  Term,  deliver to Lessor a monthly
report,  in such form and containing such  information as set forth in EXHIBIT F
hereof.

                  (q) Lessee shall, at the end of each calendar quarter,  have a
long term debt to equity ratio of not more than 4:1 as  determined in accordance
with generally accepted accounting principles consistently applied. For purposes
hereof, debt shall exclude all off balance sheet financing and operating leases.

                  (r) Lessee shall, at the end of each calendar quarter,  have a
ratio  of  current  assets  to  current  liabilities  of not  less  than  1:1 as
determined  in  accordance  with  generally   accepted   accounting   principles
consistently applied.

            12.    INDEMNIFICATION.

                  (a) GENERAL  INDEMNITY  AND EXPENSES.  Lessee  hereby  assumes
liability for, and hereby agrees to, indemnify,  protect, save and keep harmless
Lessor,  KGAL and their  respective  Affiliates,  agents,  officers,  directors,
employees,  successors  and  permitted  assigns (each of the foregoing and their
respective Affiliates,  agents, officers, directors,  employees,  successors and
assigns  being  hereinafter  referred to as an  "INDEMNITEE"  and any  reference
herein  to an  Indemnitee  shall  include  its  respective  Affiliates,  agents,

<PAGE>

officers,  directors,  employees,  successors  and  permitted  assigns) from and
against,  and on written demand to pay, or to reimburse each  Indemnitee for the
payment of, as the case may be, any and all  liabilities,  obligations,  losses,
damages, penalties, claims (including, without limitation, claims arising out of
negligence  or involving  strict  liability  in tort),  suits,  actions,  costs,
expenses  and  disbursements,   including  without  limitation  legal  fees  and
expenses,  of  whatsoever  kind and nature  imposed on,  incurred by or asserted
against  any  Indemnitee  relating  to or  arising  out of (A) this  Lease,  any
payments made pursuant  hereto or the exercise of rights or remedies  hereunder,
(B) the  preparation,  negotiation,  execution  and delivery of any  amendments,
modifications  or  waivers  required  by this Lease or  requested  by Lessee (or
resulting from any requests of Lessee) hereunder,  (C) the Aircraft, each Engine
and any Part thereof, whether or not arising out of the airworthiness, delivery,
nondelivery,   sublease,   presence,   storage,   modification,    substitution,
replacement,  alteration,  maintenance,  inspection, failure to inspect, repair,
release,  possession,  repossession  after  an Event  of  Default,  registration
(unless,  in respect of Lessor,  any act or omission  of Lessor  shall cause the
deregistration of the Aircraft under the Federal Aviation Act), use,  operation,
condition, condition upon return, return, exportation,  importation, transfer or
other application or disposition  thereof  (including,  in each case and without
limitation, latent or other defects, whether or not discoverable), any claim for
patent,  trademark  or  copyright  infringement  arising  as a  result  of or in
connection with Lessee's patents, trademarks, copyrights,  servicemarks or logos
or those of Lessee's  advertisers,  sponsors,  and others whose  designs  and/or
logos appear on the Aircraft, at any time, any claim based on strict or absolute
liability,  statutory  liability or tort and any  liability for any injury to or
death of any  person  or loss of or damage to any  property  including,  without
limitation,  any such  arising out of any test flight,  demonstration  flight or
ferry flight  performed by Lessee or any entity to which Lessee may have further
subleased  the  Aircraft  pursuant  to  SECTION 7 hereof  and (D) any breach of,
noncompliance  with or  misrepresentation  made or deemed  made in,  under or in
connection  with  this  Lease  or any  agreement  to  which  Lessee  is a  party
concerning  the  Aircraft or any  warranty,  certificate  or  agreement  made or
delivered in, under or in connection  therewith made or deemed to have been made
by Lessee or anyone claiming by, through or under Lessee;  provided, that Lessee
shall  not be  required  to  indemnify  any  Indemnitee  hereunder  (w)  for any
liability  attributable to acts or events which occur prior to the  Commencement
Date or after the Lease Term or the proper  return of the  Aircraft to Lessor in
the condition required hereunder  whichever shall occur later, (x) for liability
resulting  solely and directly  from acts of gross  negligence  or misconduct of
such Indemnitee (other than gross negligence or willful misconduct attributed to
such  Indemnitee  solely by of its interest in the  Aircraft,  any Engine or any
Part),  it being  agreed  that  gross  negligence  or willful  misconduct  of an
Indemnitee shall not affect the rights to be indemnified  hereunder of any other
Indemnitee (other than the rights of any Indemnitee that is an Affiliate, agent,
officer,  director,  employee or  successor  of any such  Indemnitee  that is so
grossly negligent or guilty of such  misconduct),  (y) for any Taxes that Lessee
has not agreed to indemnify  against pursuant to the provisions of SECTION 12(B)
or (z) for any  liability  imposed  on any  Indemnitee  arising as a result of a
disposition  of all or any part of such  Indemnitee's  interest in the Aircraft,
other than by reason of the  occurrence  of a Default or an Event of Default and
further  provided that no  indemnification  hereunder shall be paid by Lessee to
Indemnitees  in respect of any claim  arising  during  any period  during  which
Lessee is deprived of use and possession of the Aircraft as a result of a breach
by Lessor of its  covenant of quiet  enjoyment  provided  that such claim is not
caused by any act or omission of Lessee.

            If any  Indemnitee  shall have  knowledge  of any claim or liability
required to be  indemnified  against under this SECTION 12(A),  such  Indemnitee
shall give  prompt  written  notice  thereof to Lessee,  but the failure of such
Indemnitee so to notify Lessee shall not relieve  Lessee from any liability that
it would otherwise have to such Indemnitee  hereunder  except to the extent that
Lessee's  rights  respecting any defense  thereto are irrevocably and materially
impaired directly and solely as a result of such failure.
<PAGE>

            Lessee  shall be  obligated  to each  Indemnitee  under this SECTION
12(A)  irrespective  of whether any Indemnitee  shall also be  indemnified  with
respect to the same matter under any other  agreement,  and each  Indemnitee may
proceed directly against Lessee under this SECTION 12(A) without first resorting
to any such other rights of indemnification.

            Any  payment or  indemnity  pursuant  to this  SECTION  12(A)  shall
include the amount, if any, necessary to hold each Indemnitee  harmless on a net
after-tax  basis  from all  Taxes  required  to be paid by such  recipient  with
respect to such payment or indemnity  under laws,  rules or  regulations  of any
Government  Entity or Taxing  Authority.  If any  Indemnitee  is  entitled  to a
permanent  tax benefit  (whether by way of deduction,  credit or otherwise)  not
taken into account pursuant to the preceding  sentence as a result of the matter
indemnified against under this SECTION 12(A), such Indemnitee shall promptly pay
to Lessee,  after such  permanent  tax benefit is realized but not before Lessee
shall have made all payments theretofore due to such Indemnitee under this Lease
and any other  agreement  in  respect of the  Aircraft,  an amount  that,  after
subtraction of any further tax savings to which such Indemnitee is entitled as a
result of the  payment  thereof,  is equal to the amount of such  permanent  tax
benefit; provided,  however, that such Indemnitee shall not be obligated to make
any payment to Lessee pursuant to this sentence so long as a Default or Event of
Default shall have occurred and be continuing or any Rent or  Supplemental  Rent
then due and owing shall not have been paid.

            Upon the  indefeasible  payment in full of any  indemnities  due and
owing under this SECTION  12(A),  Lessee shall be subrogated to any right of the
Indemnitee in respect of the matter against which indemnity has been given.

                  (b)    GENERAL TAX INDEMNITY.

                  (i)  Lessee  agrees  that each  payment  of Rent or any amount
            payable  hereunder  shall be free of all  withholdings of any nature
            whatsoever,  and in the  event  that any  withholding  is  required,
            Lessee  shall pay an  additional  amount of Rent such that after the
            deduction of all amounts required to be withheld,  the net amount of
            Rent that is actually  received by Lessor,  will equal the amount of
            Rent or any such amount payable  hereunder or such other amount,  as
            the case may be, that would be due absent such withholding,

                  (ii) Lessee  hereby agrees to indemnify and hold harmless from
            and  against,  and on  written  demand,  to pay  or  reimburse  each
            Indemnitee for the payment of, as the case may be, any and all Taxes
            imposed upon or asserted against any Indemnitee or the Aircraft, the
            Airframe,  any Engine, or any Part thereof or interest  therein,  or
            this  Lease,  or the  rentals  received  under  this  Lease,  by any
            federal,  state or local government or other taxing authority in the
            United  States,  in any  territory or  possession  thereof or by any
            foreign government or any political  subdivision or taxing authority
            thereof  or  therein  (the   foregoing   being  referred  to  herein
            individually  as a "TAXING  AUTHORITY" and  collectively  as "TAXING
            AUTHORITIES") upon or with respect to (a) the acceptance, rejection,
            delivery,   transport,   insuring,   registration,   deregistration,
            reregistration,  assembly, possession, repossession, operation, use,
            presence,  condition,   maintenance,  repair,  return,  abandonment,

            applicability  of this  Lease to the  Aircraft,  the  Airframe,  any
            Engine, or any Part thereof or any interest therein,  (d) any or all
            of  the   documents  and   agreements   relating  to  the  Aircraft,

            contemplated hereby including the exercise of remedies hereunder.

                  (iii) The  provisions  of SECTION  12(B)(I) and (II) shall not
            apply to, and Lessee  shall have no liability to Lessor or any other
            person thereunder with respect to Taxes to the extent excluded under
            any of the following provisions or any combination thereof:

                        (A) Taxes  imposed by any country,  taxing  authority or

                  would not have been due  (whether  or not from the same person
                  on whom they are actually  imposed)  but for the  transactions
                  contemplated by this Agreement,  provided that the presence or
                  activities of any person other than Lessor in any jurisdiction
                  shall not be imputed for purposes of this subparagraph (A);

                        (B) Taxes (I) imposed as a result of a sale, assignment,
                  transfer   or  other   disposition   (whether   voluntary   or
                  involuntary)  (a "Transfer") (x) by Lessor or any other person
                  (other  than  Lessee  or any  affiliate  or  transferee  of or

                  the Aircraft or in or arising  under this  Agreement or (y) of
                  any direct or  indirect  interest  in Lessor or any such other
                  person having any such legal or beneficial interest (any event
                  described in (x) or (y) being a "Lessor  Transfer") or (II) to
                  the extent  such  Taxes  exceed the amount of Taxes that would
                  have been imposed and indemnified  against by Lessee had there
                  not been a "Lessor Transfer,"  provided that the exclusion set
                  forth in this  subparagraph  (B) shall not apply to a Transfer

                  return of the Aircraft or any part thereof or interest therein
                  to the  extent  the  Taxes  relate  solely  to  such  part  or
                  interest) in accordance with the terms of this Agreement; (II)
                  the  termination  of  this  Agreement  and the  return  of the
                  Aircraft or (III) the sale or other  transfer of the  Aircraft
                  and the  return  of the  Aircraft  (or  any  part  thereof  or
                  interest therein to the extent the Taxes relate solely to such
                  part or  interest)  following a Total Loss with respect to the
                  Aircraft,  provided  that  the  exclusion  set  forth  in this
                  subparagraph  (C) shall not apply to Taxes to the extent  such
                  Taxes  relate to  periods  prior to,  or events  occurring  or
                  matters arising prior to or simultaneously with, such event;

                        (D) Taxes to the  extent  imposed as a result of (I) the
                  willful  misconduct or gross  negligence  of Lessor,  (II) the
                  breach by Lessor of any of its representations,  warranties or
                  covenants contained in this Agreement or (III) Lessor's Liens;

                  Revenue Code of 1986,  as amended (the "Code") or Section 3406
                  of  the  Code  or  any  successor  provisions  required  to be
                  withheld from any payment under this Agreement),  capital, net
                  worth,  franchise,  or  conduct of  business  of Lessor or any

                  any capital gains Taxes,  minimum Taxes,  Taxes on or measured
                  by  any  items  of  tax  preference  and  withholding  Taxes),
                  capital,  net worth,  franchise,  or conduct  of  business  of
                  Lessor or any other person  (other than Taxes in the nature of
                  sales, use, rental, property, or value-added Taxes) imposed by
                  any foreign  government,  foreign  government  subdivision  or
                  other  foreign  taxing   authority  or  by  any  territory  or
                  possession  of the  United  States,  or by  any  international
                  authority,  provided  that  the  exclusion  set  forth in this
                  subparagraph  (G) shall not  exclude  such Taxes if and to the
                  extent that such Taxes (i) would not have been imposed but for
                  the operation,  presence or registration in such  jurisdiction
                  of the Aircraft or any part  thereof,  or (ii) would have been
                  imposed  solely  as a  result  of (x)  the  presence  in  such
                  jurisdiction  of a permanent  establishment  or fixed place of
                  business of Lessee, or any user or person in possession of the
                  Aircraft or any part thereof,  (y) the residence,  nationality
                  or place of  management  and  control of Lessee or any user or
                  person in possession of the Aircraft or any part thereof,  (z)
                  the payment  from such  jurisdiction  by Lessee or any user or
                  person in  possession  of the  Aircraft or any part thereof of
                  any amount due hereunder,  or (iii) any combination of clauses
                  (i) and (ii);

                        (H) Taxes that would not have been  imposed  but for any
                  failure of Lessor to (x) file  proper  and  timely  reports or
                  returns or to pay any Taxes when due,  or (y) comply  with any
                  certification,  information, documentation, reporting or other
                  similar  requirements  concerning the nationality,  residence,
                  identity or  connection  with the  jurisdiction  imposing such
                  Taxes,  if such  compliance is required to obtain or establish
                  relief or exemption from or reduction in such Taxes and Lessor
                  was eligible to comply with such requirement.

                        (I) Taxes imposed under Section 887 of the Code.

Notwithstanding  any provision in this SECTION 12 to the contrary,  Lessee shall
in no event be obligated to pay any amount pursuant to this SECTION 12 in excess
of the Taxes  Lessee  would be required by this  SECTION 12 to pay if (i) Lessor
were  the  lessor  of the  Aircraft  and (ii) no  person  other  than the  owner
participant as of the date hereof pursuant to the 1997 Trust Agreement,  Lessor,
Lessee or any sublessee or other user or person in possession of the Aircraft or
any part thereof had any interest in the Aircraft or part thereof.

                  (c)    CALCULATION OF TAX INDEMNITY PAYMENTS.

                  (i) Any payment  that  Lessee  shall be required to make to or
            for the account of any  Indemnitee  with  respect to any Tax that is
            subject to  indemnification  under  SECTION  12(B) shall include the
            amount necessary to hold such Indemnitee harmless on a net after-tax
            basis from the net amount of all Taxes  required  to be paid by such
            Indemnitee as the result of such payment pursuant to the laws of any
            Taxing Authority.

                  (ii) If Lessor  shall  realize a Tax benefit as a result of or
            with  respect  to any Taxes  paid or  indemnified  against by Lessee
            under  this  SECTION  12  (whether  by way of  deduction,  credit or
            otherwise),  Lessor shall pay to Lessee,  promptly after realization
            of such Tax benefit, an amount that, prior to the application of any
            withholding tax to that payment but after subtraction of any further
            Tax savings Lessor realizes as a benefit,  provided that if any such
            Tax benefit is  subsequently  disallowed,  lost or  reduced,  Lessee
            shall,  upon written notice from Lessor,  promptly repay the amounts
            paid to the  Lessee  with  respect  to such  Tax  benefit,  provided
            further  that  Lessor  shall not be  obligated  under  this  SECTION
            12(C)(II)  to pay Lessee any amounts  with  respect to Tax  benefits
            realized as a result of any Taxes not paid or indemnified against by
            Lessee. Notwithstanding anything to the contrary in this SECTION 12,
            if,  at the time  any  payments  would  otherwise  be due to  Lessee
            pursuant to this SECTION  12(C)(II),  an Event of Default shall have
            occurred  and be  continuing,  Lessor  shall hold the amount of such
            payment  as  security  for the  obligations  of the Lessee to Lessor
            under the Lease  and at such time as there  shall not be  continuing
            any such Event of Default,  shall pay such amount to Lessee.  Lessor
            shall use reasonable efforts in good faith in filing its Tax returns
            and in dealing with taxing authorities to seek and to claim any such
            Tax  benefit  or  savings  and to  minimize  the  Taxes  payable  or
            indemnifiable by Lessee hereunder.

                  (iii) At Lessee's  request,  the  computation by Lessor of any
            amount  payable  by  Lessee  pursuant  to this  SECTION  12 shall be
            verified by an independent  accounting  firm of national  reputation
            selected by Lessor.  The fees of such  accountants  shall be paid by
            Lessee unless such accountants  determine that the amount payable to
            Lessee is at least 25% more,  or the amount  payable by Lessee is at
            least 25% less,  than the amount  computed by Lessor,  in which case
            such fees shall be payable by Lessor.

                  (d)    CONTEST; REPORTS.

                  (i) If a claim is made in writing  against Lessor  (whether on
            audit or otherwise)  for any Taxes that Lessee is required to pay or
            indemnify  against  pursuant to SECTION  12(B),  Lessor shall notify
            Lessee in writing  within 30  Business  Days of the  receipt of such
            claim,  provided  that a failure to so notify  will not  diminish or
            relieve Lessee of any obligations under SECTION 12(b), except to the
            extent  Lessee is entitled to contest or to cause  Lessor to contest
            such Taxes and Lessee's or Lessor's successful defense of such claim
            is materially  prejudiced or precluded thereby. If the amount of the
            claim  exceeds $[ ]* and if requested by Lessee in  accordance  with
            this  SECTION  12(D) and in writing  within 30  Business  Days after
            receipt by Lessee of the notice described in the preceding sentence,
            Lessor shall in good faith and with due diligence contest (including
            pursuing all  administrative  and  judicial  appeals) in the name of
            Lessor or, if permitted  by law and  requested by Lessee in the name
            of Lessee,  the validity,  applicability  or amount of such Taxes in
            appropriate  administrative or judicial proceedings to be determined

<PAGE>

            by Lessor,  provided  that (1) prior to taking such  action,  Lessee
            shall have agreed to pay Lessor all out-of-pocket costs and expenses
            that  Lessor may incur in  connection  with  contesting  such claim,
            including, without limitation, all reasonable legal and accountant's
            fees and  disbursements  and costs of  administrative  and  judicial
            proceedings, and the amount of any interest or penalties that may be
            attributable  to and  payable as a result of  contesting  such claim
            (or, at Lessor's request,  Lessee shall advance to Lessor funds with
            which to pay the  foregoing  amounts,  and  Lessor's  obligation  to
            contest any Tax shall be suspended during any period Lessee does not
            advance  sufficient  funds to pay such  amounts  as they  accrue  or
            become  payable),  (2) if such  contest  is to be  initiated  by the
            payment  of,  and the  claiming  of a refund for such Taxes (and any
            interest and  penalties  that also must be paid),  Lessee shall have
            advanced Lessor sufficient funds (on an interest-free basis) to make
            such  payment,   (3)  no  Event  of  Default  has  occurred  and  is
            continuing, (4) the action to be taken will not result in a material
            risk of sale,  forfeiture or loss of Lessor's  title to the Aircraft
            (unless  Lessee  provides a bond or other security  satisfactory  to
            Lessor), and (5) at Lessor's request, Lessee shall provide to Lessor
            a written  opinion in form and substance  satisfactory  to Lessor of
            independent  legal  counsel  satisfactory  to Lessor that there is a
            reasonable  basis  for  such  contest.   Notwithstanding   that  the
            conditions set forth in clauses (1), (2), (3), (4) and (5) above may
            have been  satisfied,  Lessor,  after  consulting in good faith with
            Lessee,  may elect not to pursue any contest or proceeding  pursuant
            to the preceding  sentence or elect to discontinue (by settlement or
            otherwise) any such contest or proceeding  commenced pursuant to the
            preceding  sentence,  but such election shall constitute a waiver by
            Lessor  of any  right to  payment  or  indemnification  pursuant  to
            SECTION 12(B) with respect to the adjustment that was the subject of
            such proposed  contest or proceeding  (and any other  adjustment the
            contest of which is precluded  by such  failure to contest)  and, if
            Lessee has theretofore paid or provided Lessor with funds to pay any
            amount with respect to such adjustment,  Lessor shall promptly repay
            such amount to Lessee.  If Lessor  shall obtain a refund in whatever
            form of all or any part of any Taxes that Lessee  shall have paid or
            reimbursed to Lessor hereunder, Lessor shall, provided that no Event
            of Default shall have occurred and be  continuing,  pay to Lessee an
            amount  that is equal to the sum of the  amount  of such  refund  or
            credit,   plus  any   interest   received  on  such  refund   fairly
            attributable  to any Taxes paid by or with funds  provided by Lessee
            prior to receipt of such  refund,  reduced by any Taxes  incurred by
            Lessor  by reason of the  receipt  or  accrual  of such  refund  and
            interest  and net of any  expenses  described  in clause  (1) of the
            second  sentence of this SECTION 12(D) that have not been previously
            reimbursed, and increased by any Tax benefit realized by Lessor as a
            result of any  payment by Lessor  made  pursuant  to this  sentence,
            provided  further that,  if, at the time of such payment an Event of
            Default shall have occurred and be continuing, Lessor shall hold the
            amount of such payment as security for the  obligations of Lessee to
            Lessor  under  the  Lease,  and at such  time as there  shall not be
            continuing  any such Event of Default,  shall pay such amount to the
            Lessee.  Lessor hereby agrees that it will inform Lessee of the time
            and place of, and Lessor  will not object to Lessee's  presence  at,
            any proceeding  conducted  pursuant to this SECTION 12(D),  provided
            that Lessee's  presence  also must be allowed by applicable  law and
            provided  further that the conditions set forth in clauses (1), (2),
            (3),  (4) and (5) above shall have been,  and shall  continue to be,
            satisfied.

                  (ii) Lessee shall provide Lessor with such  information in the
            possession  of Lessee or  otherwise  reasonably  available  to it as
            Lessor may  reasonably  require to enable  Lessor to fulfill its tax
            filing  obligations  under this SECTION 12 and any audit information
            request arising in connection with the Taxes subject to this SECTION
            12.  Lessor  shall  provide  Lessee  with  such  information  in the
            possession  of Lessor or  otherwise  reasonably  available  to it as
            Lessee may reasonably request to fulfill its tax filing requirements
            under this SECTION 12 and any audit  information  request arising in
            connection  with the Taxes subject to this SECTION 12. If any report
            or return is required to be made with respect to any  obligation  of
            Lessee  under  this  SECTION  12,  Lessee  will make such  report or
            return,  provided  that Lessee shall have no  obligation to file any

<PAGE>

            such return or report if (A) Lessor,  after Lessee's written request
            therefor,  shall have failed to furnish Lessee with such information
            as is peculiarly  within the control of, or reasonably  available to
            Lessor and is necessary for the filing of such report or return,  or
            (B) such return or report  would or should have been filed by Lessor
            even if it had not entered into the Lease.

                  (iii) Lessor  shall  furnish from time to time to Lessee or to
            such other person as Lessee may designate, such returns,  statements
            or other documentation ("Tax Forms") (including, without limitation,
            if then required,  information as to the ultimate  beneficial owners
            of  Lessor  and the stock  interests  in Lessee  held  actually  and
            constructively  by Lessor, if not otherwise known to Lessee) in such
            form and with such  substance  as are  necessary or  appropriate  to
            enable  Lessor or  Lessee,  to claim an  available  reduction  of or
            exemption  from  Taxes  which  Lessee  may  be  required  to  pay or
            indemnify  against  hereunder,   provided  that  Lessee  shall  have
            provided Lessor with any information  within the Lessee's control or
            reasonably  available  to Lessee that is  necessary  to prepare such
            return,  statement or other documentation.  Any such Tax Forms shall
            be provided  promptly  after receipt of a written  request  therefor
            from the Lessee.

                  (e) PAYMENT.  Unless  otherwise  requested by the  appropriate
Indemnitee, Lessee shall pay when due any Tax for which it is liable pursuant to
SECTION 12(B) directly to the  appropriate  Taxing  Authority,  or, upon written
demand,  shall reimburse the appropriate  Indemnitee for the payment of any such
Tax made by such  Indemnitee.  Within 30 days after the date of each  payment by
Lessee of any Tax referred to in the  preceding  sentence,  Lessee shall furnish
the  appropriate  Indemnitee  evidence of payment of such Tax acceptable to such
Indemnitee. Lessee shall also cause to be furnished, promptly upon request, such
data as any  Indemnitee  may  reasonably  require  from  Lessee to  enable  such
Indemnitee to comply with the requirements of any Taxing Authority in respect of
any Tax referred to in SECTION 12(B).

                  (f)  SURVIVAL.  The  obligations  contained in this SECTION 12
shall survive the termination of this Lease, to the extent they have accrued, or
relate to events that have occurred,  on or before the date of such termination;
provided that obligations  arising as a result of the occurrence of a Default or
an Event of Default shall in any event, without limiting the foregoing,  survive
until  payment  in  full  and  performance  of all  obligations  owing  to  each
Indemnitee under the foregoing  agreements and all other agreements  referred to
herein or contemplated  hereby. The obligations of Lessee in respect of all such
indemnities,  obligations,  adjustments  and payments are expressly made for the
benefit of, and shall be enforceable by, each Indemnitee entitled thereto at the
option of such  Indemnitee  without  declaring  this  Lease to be in  default or
taking any other action hereunder.

            13.    ASSIGNMENT; LEASE SUBJECT AND SUBORDINATE.

                  (a) NO IMPERMISSIBLE  SUBLEASE BY LESSEE.  EXCEPT AS OTHERWISE
EXPRESSLY PROVIDED HEREIN,  LESSEE SHALL NOT ASSIGN OR OTHERWISE TRANSFER IN ANY
MANNER ANY OF ITS RIGHTS OR INTERESTS WITH RESPECT TO THIS LEASE,  THE AIRCRAFT,
ANY ENGINE OR ANY PART THEREOF.

                  (b)    [Intentionally left blank.]
<PAGE>

                  (c) LEASE SUBJECT AND  SUBORDINATE.  Lessee  acknowledges  and
agrees  that  this  Lease,  and  Lessee's  rights  hereunder,  are  subject  and
subordinate  in all respects to any Lien that Lessor may grant over the Aircraft
and the benefit of this Lease as provided in SECTION 13(D),  including,  without
limitation,  any  rights  to  repossession  of  the  Aircraft  upon  a  default.
Notwithstanding anything to the contrary herein, upon the occurrence of an event
of default  entitling  any Assignee (as defined  below) to demand  return of the
Aircraft by Lessor  under the Lease,  Lessee  shall,  if  requested  to do so by
Lessor  or  Assignee,  as the case may be,  return  the  Aircraft  to  Lessor or
Assignee, as the case may be.

                  (d)   ASSIGNMENTS  BY  LESSOR.   Subject  to  Lessee's  rights
hereunder and at Lessor's  cost and expense,  Lessor may at any time and without
Lessee's consent sell,  assign or transfer its rights and interest  hereunder or
with  respect to the  Aircraft  to a third  party  and/or  grant a Lien over the
Aircraft  and the benefit of this Lease to any Person as security  for  Lessor's
obligations to such Person (each such transferee,  assignee or other Person,  an
"ASSIGNEE").  On request by Lessor, Lessee will execute all such documents (such
as a lease  assignment  agreement) as Lessor may  reasonably  require to confirm
Lessee's  obligations  under this  Lease.  No sale,  assignment  or  transfer of
Lessor's  interest  or  creation of any Lien by Lessor  shall  adversely  affect
Lessee's  rights  hereunder  or  increase  Lessee's  duties,   expenses  or  the
liabilities of Lessee in respect of any Tax or under any of its  indemnification
obligations or otherwise.  Lessee will provide all other  reasonable  assistance
and  cooperation to Lessor and any Assignee in connection  with any such sale or
assignment or the perfection  and  maintenance of any Lien granted in connection
therewith,  including,  at Lessor's sole cost and expense,  making all necessary
filings and  registrations  including  filings or  registrations  of  mortgages,
financing  statements  and  re-registration  of  the  Aircraft.  Upon  any  such
assignment  or  transfer,  Lessor  shall cause any Assignee to deliver to Lessee
evidence of its corporate  authority to enter into any such sale,  assignment or
transfer and such Assignee  shall grant to Lessee the same  covenant(s) of quiet
enjoyment as are set forth  herein.  Wherever the term  "Lessor" is used in this
Lease in relation to any of the  provisions  relating to  disclaimer,  title and
registration,  indemnity and insurance, such terms shall be construed to include
each Assignee, as applicable.

            14.    EVENTS OF DEFAULT; REMEDIES.

                  (a) EVENTS OF DEFAULT.  The occurrence of any of the following
events shall  constitute an "EVENT 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 it
shall not have been remedied:

                  (i)  Lessee  shall  fail to make any  payment  of Basic  Rent,
            Maintenance  Reserves,  Stipulated Loss Value or  Supplemental  Rent
            hereunder  within five (5)  Business  Days after the same shall have
            become due and payable;

                  (ii) Lessee shall fail to carry and  maintain  insurance on or
            with respect to the Aircraft in  accordance  with the  provisions of
            SECTION  9 hereof or  Lessee  shall  fail to  provide  an  insurer's
            certificate  evidencing  the renewal or  replacement of such policy,
            upon the renewal or  replacement  thereof,  in  accordance  with the
            terms hereof;

                  (iii) any document  required to be filed or recorded by Lessee
            pursuant hereto is not duly filed and recorded by Lessee as required
            to perfect and continue the  perfection of the interest of Lessor in
            the Aircraft or the filings and  recordings  provided for herein are
            not made by the time  required;  or Lessee  shall fail to perform or
            observe any other  covenant,  term,  condition  or  agreement  to be

<PAGE>

            performed  or  observed  by it  hereunder  or under any  instrument,
            document or agreement  furnished  by Lessee to Lessor in  connection
            with the transactions referred to herein or contemplated hereby, and
            such failure shall  continue  unremedied for a period of thirty (30)
            days after  written  notice  thereof  to Lessee or thirty  (30) days
            after Lessee, assuming exercise of reasonable diligence, should have
            known of such failure;  provided,  however,  such failure to observe
            any covenant,  term, condition or agreement does not pose a material
            danger to the rights and interests of Lessor in the Aircraft and the
            same is of such a nature that it can be cured; and, further provided
            that Lessee shall have  commenced and shall  diligently  pursue such
            cure,  Lessee shall have an additional thirty (30) day period within
            which to cure the same;

                  (iv) any  representation  or warranty made by Lessee herein or
            in any document,  or  certificate  furnished by Lessee in connection
            herewith  shall at any time prove to have been false or incorrect in
            any material respect at the time made;

                  (v) Lessee shall (A)  voluntarily  commence any  proceeding or
            file any petition  seeking relief under any  applicable  bankruptcy,
            insolvency,  liquidation  or similar law now or hereafter in effect,
            (B) consent to the institution of, or fail to contravene in a timely
            and  appropriate  manner,  any such  proceeding or the filing of any
            such  petition,  (C) apply for or  consent to the  appointment  of a
            receiver,  trustee,  custodian  sequestrator or similar official for
            itself or for a substantial part of its property or assets, (D) file
            an answer  admitting the material  allegations  of a petition  filed
            against it in any such proceeding, (E) make a general assignment for
            the benefit of creditors,  (F) become  unable,  admit in writing its
            inability  or fail  generally to pay its debts as they become due or
            (G) take  corporate  action for the purpose of effecting  any of the
            foregoing;

                  (vi) an  involuntary  proceeding  shall  be  commenced  or for
            involuntary  petition  shall  be  filed  in  a  court  of  competent
            jurisdiction  seeking  (A)  relief in  respect  of  Lessee,  or of a
            substantial  part of the  property  or assets  of  Lessee  under any
            applicable bankruptcy, insolvency,  receivership or similar law, (B)
            the appointment of a receiver, trustee,  custodian,  sequestrator or
            similar  official  for  Lessee  or  for a  substantial  part  of the
            property of Lessee or (C) the  winding-up or  liquidation of Lessee;
            and such proceeding or petition shall continue undismissed, unstayed
            or unbonded  for sixty (60) days or an order or decree  approving or
            ordering any of the foregoing shall continue  unstayed and in effect
            for thirty (30) days;

                  (vii) Lessee or any subsidiary thereof,  the debt of which has
            been  guaranteed by Lessee  thereof shall fail to pay, in accordance
            with its  terms  and  when  due and  payable,  the  principal  of or
            interest on any Debt the principal amount of which exceeds $[ ]* and
            the maturity of any such Debt, in accordance  with the provisions of
            any such Debt or any contract evidencing, providing for the creation
            of or concerning such Debt shall have been  accelerated or any event
            shall have occurred and be  continuing  that would permit any holder
            or holders of such Debt,  any  trustee or agent  acting on behalf of
            such holder or holders or any other  Persons so to  accelerate  such
            maturity;

                  (viii) final judgment for the payment of money in excess of $[
            ]* not fully  covered by  insurance  (or the  equivalent  in another
            currency) shall be rendered against Lessee and the same shall remain
            undischarged for a period of thirty (30) days during which execution
            of such  judgment  shall  not be  effectively  stayed or bonded in a
            manner satisfactory to Lessor;
<PAGE>

                  (ix) Lessee shall fail to remain a "certificated  air-carrier"
            within the meaning of the Federal Aviation Act;

                  (x) Lessee shall voluntarily  suspend all or substantially all
            of  its   commercial   airline   operations,   or  the   franchises,
            concessions,  permits, rights or privileges acquired for the conduct
            of the business and  operations of Lessee shall be revoked  canceled
            or otherwise  terminated  or the free and continued use and exercise
            thereof curtailed or prevented;

                  (xi) except as otherwise  permitted  pursuant to SECTION 11(N)
            hereof,  Lessee shall merge with or into or consolidate with or into
            or convey,  transfer,  lease or otherwise dispose of (whether in one
            transaction or in a series of transactions) all or substantially all
            of its  assets  (whether  now owned or  hereafter  acquired)  to any
            Person or fifty-one  percent  (51%) or more of the capital  stock of
            Lessee  shall be  acquired  in a single  transaction  or  series  of
            transactions,  directly  or  indirectly  by any  Person  and/or  its
            Affiliates not a shareholder of Lessee on the Commencement Date;

                  (xii)  possession of the Aircraft,  the Airframe or any Engine
            shall be  transferred  to another  Person,  other than in accordance
            with the express provisions of SECTION 7(D); and/or

                  (xiii) the Aircraft shall cease to be (or cease to be eligible
            to be)  registered  in the  United  States as a result of any act or
            omission of Lessee .

                  (b) REMEDIES.  Upon the occurrence of any Event of Default and
at any time  thereafter so long as the same shall be continuing,  Lessor may, at
its option,  declare this Lease to be in default by notice to Lessee; and at any
time  thereafter,  so long as Lessee  shall not have  remedied  all  outstanding
Events of Default  before Lessor shall have  commenced to exercise its rights or
remedies hereunder,  Lessor may exercise one or more of the following rights and
remedies with respect to all or any part of the Aircraft, Airframe or any Engine
as 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:

                  (i) cause  Lessee,  upon the  written  demand of Lessor and at
            Lessee's  expense,  to return  promptly,  and  Lessee  shall  return
            promptly  (and in no event  later than two days after such  demand),
            all or such part of the  Aircraft,  the  Airframe  or any  Engine as
            Lessor  may  demand,  to  Lessor  or its  order  in the  manner  and
            condition  required  by, and  otherwise in  accordance  with all the
            provisions of,  SECTION 10 as if such  Aircraft,  Airframe or Engine
            were being returned at the end of the Lease Term, or Lessor,  at its
            option,  may enter  upon the  premises  where all or any part of the
            Aircraft,  Airframe  or any  Engine is  located  and take  immediate
            possession of and remove the same;

                  (ii) hold, use,  operate,  keep idle or lease to others all or
            any part of the Aircraft,  with or without taking possession thereof
            as Lessor in its sole  discretion may  determine,  free and clear of
            any rights of Lessee and  without any duty to account to Lessee with
            respect to such action or inaction or for any proceeds  with respect
            thereto,  except that Lessee's obligation to pay Basic Rent pursuant
            to the Lease for any  periods  in respect  of the  Aircraft  or part
            thereof accruing after Lessee shall have been deprived of possession
            of such  Aircraft or part thereof  pursuant to this SECTION 14 shall
            be reduced by the net  proceeds,  if any,  received  by Lessor  from
            leasing the Aircraft or part thereof to any Person other than Lessee
            for the same periods or any portions thereof;
<PAGE>

                  (iii)  Lessor may  exercise any other right or remedy that may
            be available to it under  applicable  law or proceed by  appropriate
            court action to enforce the terms  hereof or to recover  damages for
            the breach or to rescind this Lease;

                  (iv) Lessor may terminate this Lease; and/or

                  (v)  whether or not  Lessor  shall  have  exercised,  or shall
            thereafter  at any time  exercise,  any of its rights under  clauses
            (i), (ii), (iii) or (iv) above,  Lessor, by written notice to Lessee
            specifying a payment  date not earlier  than five (5) Business  Days
            after the date of such notice,  may terminate  this Lease and demand
            that  Lessee pay to Lessor and  Lessee  shall pay to Lessor,  on the
            payment date  specified in such notice,  as  liquidated  damages for
            loss of a bargain  and not as a penalty,  the sum of: (A) any unpaid
            Basic Rent due under this  Agreement for periods  ending on or prior
            to the  payment  date  specified  in  such  notice  and  any  unpaid
            Supplemental  Rents due on or prior to such payment date,  plus (B),
            an amount  equal to the  aggregate  unpaid  Basic Rent  which  would
            otherwise  have accrued  hereunder  over the  remainder of the Lease
            Term but for the Event of Default, discounted to present value as of
            the  date  specified  for  payment  in such  notice,  less  (C),  if
            applicable,  for any period until the  expiration  of the Lease Term
            that Lessor has not been able to sublease  the Aircraft but has been
            able,  in the normal  course of its  operations to use the Aircraft,
            the Basic  Rent  payable  by  Lessee to Lessor  for the lease of the
            Aircraft  during any such period of use  discounted to present value
            as of the date  specified  for payment in such  notice.  The amounts
            specified  in such notice  shall bear  interest at the  Post-Default
            Rate from the payment date specified in such notice until payment is
            made. In  calculating  Lessor's  damages  hereunder upon an Event of
            Default,  all Basic  Rent  which  would  have  become due during the
            remainder  of the Lease Term if an Event of Default had not occurred
            will be calculated on a present value basis using a discounting rate
            equal to the rate of interest on United States Treasury Bills having
            a maturity which will most closely  approximate  the period equal to
            the  remainder  of the Lease  Term,  as  quoted  in the Wall  Street
            Journal on the date of Lessor's notice.

            In addition,  Lessee shall be liable,  except as otherwise  provided
above,  for any and all  unpaid  Basic  Rent  and  Supplemental  Rent  then  due
hereunder  before  or  during  or after  the  exercise  of any of the  foregoing
remedies and for all legal fees and other costs and expenses  incurred by Lessor
by reason of the  occurrence of any Event of Default or the exercise of Lessor's
remedies  with respect  thereto,  including  all costs and expenses  incurred in
connection with the return of all or any part of the Aircraft in accordance with
SECTION 10 or this SECTION 14 or in storing or  maintaining  the Aircraft or any
part thereof or placing the same in the condition and airworthiness  required by
SECTION 10.

            Except as otherwise  expressly provided above, no remedy referred to
herein is intended to be exclusive, but each shall be cumulative and in addition
to any other remedy  referred to herein 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 such other remedies; provided, that Lessor may recover only
once from each element of damages  sustained  and,  provided  further,  that the
preceding  proviso  shall not be deemed to  require  proof of  damages  actually
sustained in the case of liquidated  damages provided for herein.  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.  To the extent permitted by law, Lessee hereby waives any rights now or

<PAGE>

hereafter  conferred  by statute or  otherwise  (A) that may confer any right to
prior notice or judicial  hearing in connection with Lessor's taking  possession
or disposing of the Aircraft including,  without  limitation,  any and all prior
notice and hearing  for any  prejudgment  remedy or remedies  and any such right
that Lessee might otherwise have under applicable law, (B) except as provided in
this SECTION 14, that impose any  requirements as to the time, place or terms of
lease other disposition or other requirements with respect to the enforcement of
Lessor's  rights  and  remedies   hereunder,   (C)  all  rights  of  redemption,
appraisement,  valuation,  stay,  extension  or  moratorium  now or hereafter in
effect under applicable law that may have the effect of delaying the enforcement
of this Lease or the absolute lease or other disposition of the Aircraft, or (D)
except as otherwise  provided herein,  that may otherwise limit or modify any of
Lessor's  rights  or  remedies  hereunder.  The  failure  or delay of  Lessor in
exercising  any right or remedy  granted it hereunder upon any occurrence of any
of the  contingencies set forth herein shall not constitute a waiver of any such
right or remedy upon the continuation or recurrence of any such contingencies or
similar  contingencies  and any  single or  partial  exercise  hereunder  of any
particular  right or remedy of Lessor shall not exhaust the same or constitute a
waiver of any other right provided herein.

            Notwithstanding  anything  contained  in  this  SECTION  14  to  the
contrary, Lessor shall use reasonable efforts to mitigate damages.

            16.    GOVERNING LAW AND JURISDICTION.

                  (a)  GOVERNING  LAW.  This  Lease  shall  in all  respects  be
governed by, and construed in accordance with, the internal laws of the State of
New York, inclusive of all matters of construction, validity and performance.

                  (b) JURISDICTION; SERVICE OF PROCESS. Lessee and Lessor hereby
irrevocably  submit to the  jurisdiction  of any New York State or federal court
sitting in New York City in any action or proceeding  arising out of or relating
to this Lease, and hereby  irrevocably  agree that all claims in respect of such
action or  proceeding  may be heard and  determined in such New York State court
or, to the extent  permitted  by law, in such federal  court.  Lessee and Lessor
hereby  irrevocably waive, to the fullest extent they may effectively do so, the
defense  of  an  inconvenient  forum  to  the  maintenance  of  such  action  or
proceeding.  Lessee hereby irrevocably  appoints CT Corporation  System, with an
office on the date hereof at 1633 Broadway, New York, New York 10019, and Lessor
hereby irrevocably  appoints CT Corporation  System,  with an office on the date
hereof at 1633  Broadway,  New York,  New York 10019 (the "PROCESS  AGENT"),  as
their  respective  agents to  receive  on their  behalf  and in respect of their
proper service of copies of the summons and complaint and any other process that
may be served in any such  action or  proceeding.  Such  service  may be made by
mailing or  delivering a copy of such  process to Lessee or Lessor,  as the case
may be, in care of their respective Process Agents at such Process Agent's above
address,  and Lessee and Lessor  hereby  irrevocably  authorize and direct their
respective  Process  Agents  to  accept  such  service  on their  behalf.  As an
alternative method of service, Lessee and Lessor also irrevocably consent to the
service of any and all process in any such action or  proceeding  by the mailing
of copies of such  process to the address  specified  in SECTION 15.  Lessee and
Lessor  agree that a final  judgment in any such action or  proceeding  shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law.  Nothing in this SECTION 16(B) shall affect
the right of any Person to serve legal process in any other manner  permitted by
law or affect  the right of any other  party to bring any  action or  proceeding
against Lessee or Lessor, or their respective  properties in the courts of other
jurisdictions.  LESSEE AND LESSOR  HEREBY  WAIVE  TRIAL BY JURY IN ANY  JUDICIAL
PROCEEDING  TO WHICH THEY ARE PARTIES  INVOLVING,  DIRECTLY OR  INDIRECTLY,  ANY
MATTER ARISING OUT OF OR RELATING TO THIS LEASE.

                  (c) WAIVER OF  IMMUNITY.  To the extent  that Lessor or Lessee
has or hereafter  may acquire any sovereign  immunity,  Lessor and Lessee hereby
irrevocably waive such immunity in respect of their respective obligations under
this Lease and all other  documents and agreements  relating to the Aircraft and
the transactions referred to or contemplated herein.

<PAGE>

            17.    MISCELLANEOUS.

                  (a)  ENTIRE  AGREEMENT.  This  Lease  constitutes  the  entire
agreement  between  the  parties  concerning  the  subject  matter  hereof,  and
supersedes all previous proposals, agreements, understandings,  negotiations and
other  written  and oral  communications  in relation  hereto.  NO LEASE TERM OR
PROVISION OF THIS LEASE MAY BE CHANGED, WAIVED, DISCHARGED OR TERMINATED, EXCEPT
(i) WITH THE PRIOR  WRITTEN  CONSENT  OF  LESSOR  AND (ii) BY AN  INSTRUMENT  IN
WRITING SIGNED BY A DULY  AUTHORIZED  REPRESENTATIVE  OF THE PARTY AGAINST WHICH
THE  ENFORCEMENT  OF THE CHANGE,  WAIVER,  DISCHARGE OR  TERMINATION  IS SOUGHT.
Nothing  herein shall be  construed  as conveying to Lessee any right,  title or
interest in the  Aircraft,  the  Airframe or any Engine or Part except as Lessee
under this Lease.
                  (b) ENGLISH LANGUAGE.  All notices,  communications,  reports,
opinions  and other  documents  given  under this Lease  shall be in the English
language.

                  (c) LESSOR'S  RIGHT TO PERFORM FOR LESSEE.  If Lessee fails to
make  any  payment  of  Rent  or  Supplemental  Rent  required  to be made by it
hereunder  or fails to perform or comply  with any of its  agreements  contained
herein,  Lessor may  itself  make such  payment  or perform or comply  with such
agreement,  and the amount of such  payment  and the amount of any  expenses  of
Lessor  incurred  in  connection  with such  payment  or the  performance  of or
compliance with such agreement, as the case may be, shall be deemed Supplemental
Rent payable by Lessee upon demand;  provided,  however,  that no such  payment,
performance  or compliance  by Lessor shall (i) be deemed to have  satisfied the
obligation  of Lessee to make such  payment or to  perform  or comply  with such
agreement,  as the case may be, unless and until Lessee shall have paid all such
Supplemental  Rent payable pursuant to this section by reason of such failure or
(ii) be  deemed  a  waiver  of  Lessor's  rights  and  remedies  against  Lessee
hereunder.

                  (d) APPLICATION OF PAYMENTS DURING  EXISTENCE OF Default.  Any
amount referred to herein that is payable to Lessee shall not be paid to Lessee,
or if it has been previously  paid directly to Lessee,  shall not be retained by
Lessee,  if at the time of such payment a Default or Event of Default shall have
occurred and be continuing,  but shall be paid to and held by Lessor as security
for and may be applied to the  obligations  of Lessee  under this Lease and,  at
such time as Lessor shall receive evidence in form and substance satisfactory to
it that there is not continuing  any such Default or Event of Default,  all such
amounts in excess of amounts so paid on  obligations  of Lessee shall be paid to
Lessee.

                  (e)  EXPENSES.  Lessee  agrees  to  reimburse  Lessor  for its
out-of-pocket  costs  and  expenses,  including  attorney's  fees,  incurred  in
connection with any amendments,  modifications or waivers required by this Lease
or requested by Lessee (or resulting from any requests of Lessee) hereunder.

                  (f) FURTHER ASSURANCES.  Lessee will promptly and duly execute
and  deliver to Lessor  such  further  documents  and  assurances  and take such
further  action as Lessor 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 Lessor hereunder,  including,  without limitation, if requested by Lessor, at
the expense of Lessee,  the execution and delivery of  supplements or amendments
hereto, in recordable form,  subjecting to this Lease any Replacement Engine and
the recording or filing of counterparts hereof, and all such other documents and
instruments,  in accordance  with the laws of such  jurisdictions  as Lessor may
from time to time deem advisable.


<PAGE>


                  (g) JUDGMENT CURRENCY. The obligations of Lessee in respect of
any sum due from it to Lessor hereunder shall, notwithstanding any judgment in a
currency other than Dollars, be discharged only to the extent that Lessor may in
accordance with normal banking procedures purchase, or cause to be purchased for
its account  Dollars with such other  currency;  if the Dollars so purchased are
less than the sum originally due in Dollars,  Lessee agrees to indemnify  Lessor
against such loss, and if the Dollars so purchased exceed the sum originally due
to Lessor in Dollars, Lessor agrees to remit to Lessee such excess.

                  (h) INVALIDITY OF ANY  PROVISION.  Any provision of this Lease
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.  To the fullest
extent  permitted by applicable  law,  Lessee hereby waives any provision of law
that renders any provision hereof prohibited or unenforceable in any respect.

                  (i)  CHANGES  IN LAW.  If there  shall be any  change (or such
change shall be enacted or made by notice or otherwise and shall be scheduled to
become  thereafter  effective) in the laws or treaties of the United States that
has  a  material  adverse  effect  on  the  validity,  legality,  perfection  or
enforceability  of Lessor's  rights or interest in the Aircraft or this Lease or
the validity,  legality,  perfection or enforceability of this Lease, Lessor may
terminate this Agreement, whereupon Lessee shall promptly return the Aircraft to
Lessor or its designee in the condition required hereunder.

                  (j) HEADINGS.  All section and paragraph headings and captions
are purely for  convenience  of  reference  only and shall not  modify,  define,
expand,  limit or otherwise affect any of the terms or provisions hereof and all
references  herein to numbered  sections,  unless  otherwise  indicated,  are to
sections of this Lease.

                  (k) CONSENT.  Whenever in this Lease,  the consent (whether or
not, in writing) of either Lessor or Lessee is required,  such consent shall not
be unreasonably withheld or delayed.

                  (l) THIRD PARTY  BENEFICIARIES.  Lessee  recognizes  that this
Lease confers certain rights and interests on the  Indemnitees.  Notwithstanding
that the Indemnitees are not parties to this Lease, the Indemnitees are intended
third  party  beneficiaries  of such  rights and  interests  and  Lessor  hereby
acknowledges  that  the  Indemnitees  may  enforce  such  rights  and  interests
directly, as if they were parties to this Lease.

                  (m) COUNTERPARTS.  This Lease may be executed in any number of
identical  counterparts,  all of which together will be deemed to be one and the
same instrument.  Delivery of an executed counterpart of this Lease by facsimile
will be deemed effective as delivery of an originally executed counterpart.  Any
party  delivering an executed  counterpart  of this Lease by facsimile will also
deliver an originally executed counterpart; provided the failure of any party to
deliver an  originally  executed  counterpart  of this Lease will not affect the
validity or effectiveness of this Lease.

                  (n) TRUE  LEASE.  This  Lease  shall be treated as a lease for
Federal income tax purposes.

                                    EXHIBIT E


                     FORM OF OPINION OF SUBLESSEE'S COUNSEL


To Each Person Listed
on Schedule A Hereto


Gentlemen:

      We have acted as counsel for WESTERN PACIFIC AIRLINES, INC., a corporation
organized  and existing  under the laws of  _____________  ("WPA") in connection
with the preparation,  execution and delivery of the Sublease of Lease Agreement
dated  as of  March  __,  1996  (the  "Sublease"),  between  TACA  International
Airlines,  S.A., as Sublessor,  and WPA, as Sublessee,  relating to the lease of
the Aircraft. Capitalized terms used herein and not otherwise defined shall have
the meanings defined in the Sublease.

      In that connection we have examined the following:  (i) the Sublease; (ii)
the Lease; (iii) the Security Subleases;  (iv) the Mortgage; (v) the Articles of
Incorporation and bylaws of WPA and all amendments thereto (the "Charter");  and
(vi)  such  other  documents,  agreements  and  instruments  as we  have  deemed
necessary  as a basis  for the  opinions  hereinafter  expressed.  We have  also
examined  originals  or  copies,   certified  or  otherwise  identified  to  our
satisfaction,  of such other records and such other instruments and certificates
of public officials and of officers and representatives of WPA as we have deemed
necessary or appropriate as a basis for the opinions hereinafter expressed.

      In  arriving  at  the  opinions  expressed  below,  we  have  assumed  the
genuineness of all signatures and the due authorization,  execution and delivery
by the parties  thereto (other than WPA) of each of the documents  listed above.
In  addition,  we  have  made  such  investigations  of  law as we  have  deemed
appropriate for the purpose of giving the opinions expressed below.

      On the basis of the foregoing, the further assumptions set forth below and
our  consideration of such other matters of fact and questions of law as we have
deemed relevant in the  circumstances,  and subject to the limitations set forth
below, we are of the opinion that:

      (a) WPA is a  corporation  duly  organized,  validly  existing and in good
standing under the laws of ___________ and has the corporate power and authority
to carry on its  business as presently  conducted  and to enter into and perform
its  obligations  under  the  Sublease,   the  Lease  and  all  other  documents
contemplated  thereby to which it is or will  become a party  (collectively  the
"Documents"), and holds all material licenses, certificates and permits from all
Government Entities of ______________  necessary for the conduct of its business
as now conducted.

      (b) The  execution,  delivery and  performance by WPA of the Documents (a)
have been duly authorized by all necessary  corporate action on the part of WPA,
(b) do not  require  any  stockholder  approval,  or  approval or consent of any
trustee  or  holders  of any  indebtedness  or  obligations  of WPA,  (c) do not
contravene any law, rule or regulation of any Government  Entity binding on WPA,
(d) do not  contravene  any order  binding  on WPA,  (e) do not  contravene  any
provision of the Charter of WPA, and (f) do not contravene the provisions of, or
constitute  a default  under,  or result  in the  creation  of any lien upon any
property  or  assets of WPA under any  indenture,  mortgage,  contract  or other
agreement to which WPA is a party or by which it or its  properties may be bound
or affected or any applicable law, rule or regulation, judgment, order or decree
of any  Government  Entity or court having  jurisdiction  over WPA or any of its
properties or assets. Each of the Documents has been duly executed and delivered
by WPA.

      (c) No authorization or approval  (including exchange control approval) or
other action by, and no notice to or filing  with,  any  Governmental  Entity is
required  for  the  due  execution,  delivery  and  performance  by  WPA  of the
Documents, but the failure so to record or file the Sublease will not affect the
enforceability of WPA's  obligations  under the Documents.  The Documents are in
proper form for filing and recording.

      (d) The  Documents  are the legal,  valid and binding  obligations  of WPA
enforceable against WPA in accordance with their respective terms.

      (e) The obligations of WPA under the Documents rank at least PARI PASSU in
all respects with all other unsecured  obligations of WPA and are not subject to
any law, rule or regulation of _____________ or any Governmental  Entity thereof
with regard to any preference for payment of obligations or any  rescheduling of
the payment of any debt or other obligations.

      (f) The Lease,  as assigned to WPA  pursuant  to the  Sublease,  creates a
valid leasehold interest in the Aircraft.

      (g)  There is no  pending  or,  to the  best of our  knowledge  after  due
inquiry,   threatened  action  or  proceeding   affecting  WPA  or  any  of  its
subsidiaries  before  any court,  governmental  agency or  arbitrator,  or which
affects or  purports to restrain  the making or  performance  of, or affects the
legality,  validity  or  enforceability  of the  Documents  or the  transactions
contemplated thereby.

      (h) Neither WPA nor any of its property has any immunity from jurisdiction
of any court or from any legal  process  (whether  through  service  or  notice,
attachment  prior to  judgment,  attachment  in aid of  execution,  execution or
otherwise).

      (i)  There is and  will be no Tax,  levy,  impost,  deduction,  charge  or
withholding imposed by any Taxing Authority of any relevant jurisdiction therein
or  thereof  either  (i) on or by virtue of the  execution  or  delivery  of the
Documents or any other  document to be  furnished  thereunder  or in  connection
therewith or (ii) on any payment  made, or to be made, by WPA pursuant to any of
the Documents.

      (j) It is not  necessary  to take any action in Colorado or under the laws
of Ecuador to perfect the interest of the Lessor in the Aircraft or the security
interests in favor of the Lender  which the  Mortgage or the Security  Subleases
purport  to  create in the  Aircraft,  the  Lease or any  other  portion  of the
Security  (as defined in the  Mortgage).  No person,  by  performing  any act in
Colorado including,  without limitation, the execution or recording of a bill of
sale or any security  interest,  can acquire any interest  prior in right to the
Lessor or the  interests in favor of the Lender  which the Mortgage  purports to
create in the Aircraft or any other portion of the Security.

      (k) It is not necessary  under the laws of Colorado (i) in order to enable
the  Sublessor to enforce its rights under the  Sublease,  the Lessor to enforce
its  rights  under  the Lease or the  Lender to  enforce  its  rights  under the
Mortgage, or (ii) by reason of the execution, delivery and performance of any of
the Documents that the Sublessor, the Lessor, the Lender or any Lender should be
licensed, qualified or otherwise entitled to carry on business in Colorado.

      (l) Neither  Sublessor,  Lessor nor Lender will be deemed to be a resident
domiciled  or carrying  on business or subject to taxation or other  unfavorable
consequences in Colorado by reason only of the execution,  delivery, performance
and/or enforcement of the Sublease or the Security Subleases.

      (m)  Neither  WPA  nor  any of its  subsidiaries  is,  to the  best of our
knowledge  after due  inquiry,  in breach of or default  under any  agreement to
which it is a party or which is binding on it or any of its assets.

      (n) The choice of New York law set forth (a) in the  Sublease,  the Lease,
the Security Subleases and the Mortgage,  in each case to govern such respective
document and to control the  construction  thereof,  is in each case,  under the
laws of Colorado, a valid, effective and enforceable choice of law.

      (o) A judgment  obtained  against  WPA in a court in the State of New York
pursuant  to  service  of  process  in  accordance  with the  Sublease  would be
enforceable  in Colorado  against WPA's assets  located  therein,  and execution
against WPA's assets in Ecuador to satisfy such a judgment  could be obtained in
Ecuador.

      (p) WPA has legally, validly, effectively and irrevocably submitted to the
jurisdiction  of any United  States or state courts in New York City,  New York,
and has legally,  validly,  effectively and irrevocably appointed CT Corporation
System as its authorized agent for the purposes described in the Sublease.


                                          Very truly yours,

account.  Lessor may, but shall not be obligated to, apply the Security Deposit,
in whole or in part for the  payment of any Basic Rent  owing  hereunder  or any
other  amount  owing  from  time to time by Lessee  hereunder,  or  utilize  the
Security  Deposit in whole or in part to  perform  any of  Lessee's  obligations
hereunder or  otherwise  remedy any Event of Default,  without  prejudice to any
other remedy of Lessor. Lessee shall not attempt to subject the Security Deposit
to any Lien or to assign any  interest  therein to any Person and, to the extent
of its interest  therein,  Lessee hereby grants to Lessor a Lien on the Security
Deposit and assigns and transfers to Lessor any and all of Lessee's right, title
and  interest  therein,  as  security  as provided  above,  and Lessor  shall be
entitled  to the  remedy of  offset  against  and  application  of the  Security
Deposit,  without any prior notice to or demand  against  Lessee  (except to the
extent otherwise required by applicable law), all of which are hereby waived. If
Lessor  uses  or  applies  all  or a  portion  of  the  Security  Deposit,  such
application shall not be deemed a cure of any Event of Default, until and unless
Lessee  shall have  replenished  the amount  applied  hereunder  within the time
period  provided  herein.  Lessee  shall  replenish  any  portion  or all of the
Security Deposit applied by Lessor to satisfy, in whole or in part, any Event of
Default by  depositing  with  Lessor in  immediately  available  funds an amount
sufficient to restore the Security Deposit to the Security Deposit Amount within
three (3) Business Days after Lessor's demand therefor. Within fifteen (15) days
after  redelivery of the Engine to Lessor by Lessee,  and provided the Engine is
delivered in full conformity with the return  conditions set forth in Section 10
hereof, and that Lessee has paid, in full, all amounts owing by Lessee hereunder
and performed all of its obligations hereunder, Lessor will return to Lessee the
Security Deposit,  without interest,  less any amounts applied by Lessor and not
replenished by Lessee.

reason whatsoever, (iii) any insolvency,  bankruptcy,  reorganization or similar
proceedings by or against Lessee,  (iv) the  disaffirmance  or rejection of this

nature for or on  account of the  legality,  enforceability,  validity  or other
infirmity  as to (A) any of the  terms  or  conditions  of this  Lease,  (B) any
express or implied  warranty as to the Engine or any Part thereof or (C) arising
out of or as a result of any  contract,  agreement,  assignment  or  transaction

out of relating to an act or omission of Lessee; or (x) any other circumstances,
happening or event  whatsoever,  whether or not similar to any of the  foregoing

being the  intention  of the Lessor and Lessee  that all Rent and other  amounts
payable by Lessee hereunder shall be payable in all events unless the obligation
to pay the same shall be terminated  pursuant to the express  provisions of this
Lease.  Lessee hereby waives,  to the fullest extent permitted by applicable law
any and all  rights  it may now  have  or  that  at any  time  hereafter  may be
conferred  upon it, by statute  or  otherwise,  to  terminate,  cancel,  quit or

Notwithstanding  anything contained in this Section 3(g), in the event that as a
result of a breach by Lessor or anyone  claiming by,  through or under Lessor of
its covenant of quiet enjoyment  (including any defect in title not caused by an
act or omission of Lessee), Lessee shall be deprived of possession or use of the
Engine under and in accordance with this Lease,  Lessee shall not be required to
pay  Basic  Rent  and  Maintenance   Reserves  in  respect  of  such  period  of
non-possession  of or inability to use the Engine.  Each payment of Rent made by
Lessee  shall be final as to Lessor  and  Lessee,  and  Lessee  will not seek to
recover  all or any  part  of any  such  payment  of  Rent  from  Lessor  or its
successors or assigns for any reason whatsoever.

      Nothing in this Section 3(g) or elsewhere in this Lease shall be construed
to limit  Lessee's  right to seek a recovery of any payment of Rent or any other
amount which is not due and payable  hereunder,  or to limit Lessee's rights and
remedies  to  pursue,  in a court  of law or  otherwise,  any  claim it may have
against  Lessor on account of any failure of Lessor to perform  its  obligations
hereunder or in connection herewith.

     (c) MANUFACTURER AND VENDOR WARRANTIES. Lessor hereby assigns to Lessee for
the  duration  of the  Lease  Term (so long as no Event of  Default  shall  have
occurred and be  continuing)  all  assignable  warranties,  if any, given by the
Manufacturer  and other  vendors  with  respect to the  Engine and shall  obtain
Manufacturer's  consent to such assignment.  Lessee will diligently and promptly
pursue  any valid  claims it may have  under such  warranties  and will  provide
notice of the same to  Lessor.  To the  extent  that any  warranty  given by the
Manufacturer  or  others  with  respect  to the  Engine  are not  assignable  or
otherwise made available to Lessee,  Lessor agrees, at its option, either (i) to
authorize  Lessee to take such  action to enforce  such  warranty in the name of
Lessor  as  Lessee  sees fit or (ii) to exert  reasonable  efforts  at  Lessee's
request and expense  (and  subject to Lessee  making  adequate  provision to the
satisfaction  of Lessor  with  respect  to such  expense)  to  enforce  any such
warranties  for the benefit of Lessee.  Effective on the return of the Engine or
the termination of this Lease,  whichever is earlier,  Lessee hereby assigns any
remaining warranties, and any claims thereunder, to Lessor or its designee. Upon
the exercise by Lessor of any remedies in respect of an Event of Default, and at
the latest,  upon  expiration of the Lease Term,  the benefit of all  warranties
referred  to  herein  shall  immediately  revert  and be  deemed  to  have  been
reassigned by Lessee to Lessor.


      Section 6.  MAINTENANCE; REPLACEMENT AND POOLING OF PARTS; ALTERATIONS,
                  MODIFICATIONS AND ADDITIONS.

      a)    MAINTENANCE

            (i) So long as Lessor has not  committed a breach of its covenant of
      quiet enjoyment which shall have the effect of depriving Lessee of the use
      or  possession of the Engine during the Lease Term and until the Engine is
      returned to Lessor,  Lessee shall, at its sole cost and expense,  service,
      inspect,  test,  maintain,  overhaul  and repair the Engine and all of the
      Parts  in  accordance   with  the  Lessee's  FAA  approved   airworthiness
      maintenance  and inspection  program,  a copy of which has been or will be
      delivered to Lessor on or prior to the Commencement Date (the "Maintenance
      Program") and in conformity with the rules and regulations of the FAA, (A)
      so as to keep the Engine in as good  condition  (operating  and otherwise)
      and repair as when delivered to Lessee  hereunder,  ordinary wear and tear
      excepted and  otherwise so as not to  adversely  effect the  airworthiness
      thereof,  and (B) in the same  manner  and  with the same  care as used by
      Lessee  with  respect to similar  engines  owned or operated by Lessee (it
      being  the  intention  of  the  parties   hereto  that  Lessee  shall  not
      discriminate  against the Engine in respect of any  maintenance  matters).
      Lessee shall be authorized  to amend its  Maintenance  Program;  provided,
      however,  that not withstanding  such amendment,  the Maintenance  Program
      shall,  at all times  during  the  Term,  be in full  conformity  with the
      requirements set forth above and, further provided, that Lessee shall have
      obtained  Lessor's  prior  written  consent to any  material  amendment or
      change  in  or  to  the  Maintenance  Program.  All  service,  inspection,
      maintenance,  modification,  repair and  overhaul  shall be  performed  or
      caused to be performed by Lessee in  accordance  with all  applicable  FAA
      requirements and under the Maintenance  Program, and shall be accomplished
      in  accordance  with  all  applicable  service,  inspection,  maintenance,
      modification,  repair and overhaul manuals and bulletins  published by the
      Manufacturer.  Without  limiting the  generality  of the  foregoing or the
      obligations of Lessee  hereunder,  Lessee agrees that such maintenance and
      repairs will include but will not be limited to each of the following:

                  (A)     to perform in accordance with the Maintenance
            Program all routine and non-routine maintenance work;

                  (B) to  comply on a  terminating  basis  with all  outstanding
            mandatory  orders,  and  airworthiness  directives issued by the FAA
            during the Lease Term  affecting  the Engine that have an  effective
            date for compliance  prior to, or sooner than one hundred (180) days
            after, the return date of the Engine;

                                       11
<PAGE>

                  (C)  to  incorporate  in  the  Engine  all  mandatory  service
            bulletins of the  Manufacturer  and other vendors  issued during the
            Lease Term which Lessee  schedules to  incorporate  during the Lease
            Term on engines in its Boeing 737 fleet; and

                  (D) to  maintain,  in the  English  language  (1)  the  Engine
            Documentation  and (2) any other records,  logs or other  documents,
            information  or  materials  relating  to  the  service,  inspection,
            testing,  maintenance,  modification,  overhaul  and  repair  of the
            Engine,  any Engine and any Part which are required by the FAA or by
            applicable  law, all of which shall at all times be kept current and
            up-to-date,  shall  conform with the laws of any  Government  Entity
            having  jurisdiction  and with normal  practices of  commercial  air
            carriers,  shall  disclose  the  location of the Engine and shall be
            made available for review by Lessor on reasonable notice.

            (ii)  Lessee  shall  have  designated   persons  in  its  employment
      authorized by the FAA to perform service, inspection, modifications repair
      and  alterations  of the Engine,  or shall have the same  performed on its
      behalf by an FAA approved  repair and overhaul  station in conformity with
      FAR 145  ("Approved  Repair  Facility").  In the event  Lessee has a third
      party  accomplish,  on a continuous  basis, some or all of the maintenance
      requirements under the Maintenance  Program such maintenance by said third
      party must be  accomplished  in  accordance  with the  provisions  of this
      Section 6(a). Lessor shall be entitled and Lessee shall ensure that Lessor
      is permitted to visit the  facilities of any such third party  maintenance
      performer to inspect the  maintenance  work performed and the  maintenance
      record of the Engine.

            (iii)  Any  repair  to  the  Engine  that  is  not  covered  by  the
      Manufacturer's  repair  manual  instructions  shall be subject to Lessor's
      prior written approval and shall be made under an FAA approved program.

       (b)  ENGINE RESERVES

            (i) Lessee shall pay Lessor,  as a Supplemental  Rent for the use of
      the Engine during the Lease Term,  within  fifteen (15) days following the
      last  day  of  each  calendar  month  during  the  Lease  Term  and on the
      redelivery  date,  with  respect  to the  Engine,  the  sum  (the  "Engine
      Reserves")  of (x) the  amount  determined  by  multiplying  the number of
      Flight Hours of operation of such Engine during the immediately  preceding
      month by [ ]*  Dollars  (US$[ ]*) which  amount  shall be  applied  toward
      restoration  shop  visits (the "Shop  Visit  Portion")  and (y) the amount
      determined by multiplying  the number of Cycles of operation of the Engine
      during  the  immediately  preceding  month by [ ] Dollars  (US$[ ]*) which
      amount shall be applied  toward the cost of  life-limited  parts (the "LLP
      Portion").  It is the  intent of the  parties  hereto  that the  Engine be
      operated during the Lease Term at an average Flight  Hour/Cycle ratio (the
      "Ratio") of one and seven-tenths  Flight Hours to one Cycle 1.7:1.  During
      any calendar year during the Lease Term, the total Engine Flight Hours for
      the Engine  recorded in respect of the  previous  twelve  months  shall be
      compared with the Cycles flown for the Engine and the Ratio computed.  The
      rate  payable by way of  maintenance  reserve in respect of each  complete
      Flight Hour (pro rata for part  thereof)  for the Engine  applicable  with
      respect to the Shop Visit  Portion of the Engine  Reserves due from Lessee
      after such annual  Ratio  computation  and prior to the next annual  Ratio
      computation  shall be as provided in Exhibit E hereof for such Ratio.  Any
      excess Engine  Reserves  remaining at the  expiration of the Lease Term or
      earlier termination of this Lease shall be retained by Lessor.

                                       12

            (ii) Lessee shall be entitled to  reimbursement  from the Shop Visit
      Portion of the Engine Reserves for Lessee's actual costs (without mark-up)
      incurred with respect to restoration shop visits of the Engine,  excluding
      any costs  associated with  replacement of life limited parts and the cost
      of any repairs or maintenance  required due to accidents,  abuse,  misuse,
      mishandling,  faulty  maintenance,  foreign object  damage,  elective part
      replacement or any insured event. Such reimbursement  shall be made within
      ten (10) Business Days after presentation to Lessor of appropriate written
      evidence of such  expenses  (which shall include a copy of an invoice from
      an FAA-approved  maintenance  facility indicating that the maintenance has
      been completed and identifying those engine maintenance tasks accomplished
      and the labor  and  material  breakdown  thereof,  and a receipt  from the
      maintenance  facility for payment of the invoice,  or at least such amount
      thereof as shall  exceed the portion of the Engine  Reserves  available to
      Lessee  hereunder);  provided,  that (A) the amount  reimbursed  to Lessee
      shall not exceed the amount of the Engine Reserves paid by Lessee (and not
      previously  disbursed)  allocable to the Shop Visit  Portion of the Engine
      Reserves,  and (B) in no event shall  Lessee be entitled to  reimbursement
      for any  expenses  related to removal  or  installation  of the Engine for
      maintenance  or any other  shipping  or  transportation  expenses.  To the
      extent that any amount reimbursable hereunder has not been paid by Lessee,
      such amount  shall be paid  directly  to the  maintenance  facility  which
      performed the services for which reimbursement is sought.

            (iii) Lessee shall be entitled to reimbursement from the LLP Portion
      of the Engine Reserves (i) for the full  replacement  cost of life limited
      parts  having a remaining  life of up to and  including  one  thousand two
      hundred fifty (1250) Cycles. Upon reimbursement of such replacement costs,
      Lessee  shall  deliver the  removed  life  limited  parts to Lessor at the
      overhaul facility and cause title thereto to vest in Lessor free and clear
      of all Liens  other than  Lessor  Liens,  and (ii) of such  portion of the
      replacement  cost of life limited parts having a remaining  life in excess
      of one thousand  two hundred  fifty (1250)  Cycles as  corresponds  to the
      utilized (non-remaining) portion of the life of such life limited parts as
      compared to the total life thereof when new, as expressed in Cycles.  With
      respect to such life limited  parts  having a remaining  life in excess of
      one thousand two hundred fifty (1250)  Cycles,  title to such life limited
      parts shall be deemed to vest in Lessee upon  installation  of replacement
      parts on an  Engine.  Such  reimbursement  shall be made  within  ten (10)
      Business Days after presentation to Lessor of appropriate written evidence
      of  such  costs  (which  shall  include  a  copy  of an  invoice  from  an
      FAA-approved  supplier  of such  life  limited  parts,  identifying  those
      purchased  and receipt of payment  therefor  or at least  payment for such
      portion as shall exceed the LLP Portion of the Engine  Reserves  available
      to Lessee  hereunder and of the Approved Repair  Facility  indicating that
      such life limited parts have been installed on an Engine;  provided,  that
      (A) the  amount  reimbursed  to Lessee  shall not exceed the amount of the
      Maintenance  Reserves  paid  by  Lessee  (and  not  previously  disbursed)
      allocable  to the LLP Portion of the Engine  Reserves  and (B) in no event
      shall  Lessee be entitled to  reimbursement  for any  expenses  related to
      removal,  shipping  or  transportation  expenses.  To the extent  that any
      amount  reimbursable  hereunder  has not been paid by Lessee,  such amount
      shall be paid  directly to the  supplier of the life  limited  part(s) for
      which reimbursement is sought.

       (c)  REPLACEMENT  OF PARTS.  Lessee,  at its own cost and  expense,  will
promptly  replace  all  Parts  that may  from  time to time be  incorporated  or
installed  in or  attached  to the Engine and 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,
Lessee  may,  at its own cost and  expense,  remove  in the  ordinary  course of
maintenance,  service,  repair,  overhaul or testing,  any Parts, whether or not
worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or
permanently  rendered unfit for use;  provided that Lessee will, at its own cost


                                       13
<PAGE>

and expense,  replace such Parts as promptly as possible.  All replacement Parts
shall be free  and  clear of all  Liens  (except  Permitted  Liens  and  pooling
arrangements  permitted  by  Section  6(d))  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).  All Parts at any time removed from the
Engine shall remain 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 the  Engine  and that meet the  requirements  for
replaced Parts specified  above.  Immediately upon any replacement Part becoming
incorporated  or  installed  in or  attached  to the  Engine as above  provided,
without  further act,  (i) title to the  replaced  Part shall there upon vest in
Lessee,  free and clear of Lessor's  Liens and all rights of Lessor and shall no
longer be deemed a Part  hereunder  provided,  however,  that in the case of any
Part that is replaced by a  replacement  Part subject to a pooling  arrangement,
title to such  replaced  Part shall not vest in Lessee until Lessee has complied
with Section 6(d), (ii) title to such  replacement Part shall vest in Lessor and
such replacement Part shall thereupon become subject to this Lease (subject only
to a pooling arrangement to the extent permitted by Section 6(d)) and (iii) such
replacement  Part shall be deemed part of the Engine for all purposes  hereof to
the same extent as the Parts originally incorporated or installed in or attached
to the Engine.

      Notwithstanding  the  provisions  of this Section  6(c),  provided that no
Event of Default has occurred and is continuing,  Lessee may install any part on
the Engine by way of  temporary  replacement  if: (i) there is not  available to
Lessee at the time and in the place that a part is required to be  installed  on
the Engine,  a Replacement Part complying with the requirements of Section 6(c);
(ii) it would  result in an  unreasonable  disruption  of the  operation  of the
Engine and/or the business of Lessee to ground the Engine until a Part complying
with Section 6(c) becomes available for installation on the Engine; and (iii) as
soon as  practicable  after  installation  of the same on the Engine but, in any
event, no later than the date of the next restoration shop visit (except as such
time may be extended pursuant to Section 8(a)), Lessee removes any such part and
replaces it with a part complying with Section 6(c).

     (d)  POOLING OF PARTS.  Any part  removed  from the Engine as  provided  in
Section  6(c)  may be  subjected  by  Lessee  to a  normal  pooling  arrangement
customary  in the  airline  industry  entered  into in the  ordinary  course  of
Lessee's business with financially and  operationally  responsible air carriers;
provided,  that the Part  replacing such removed Part shall be  incorporated  or
installed  in or  attached  to the Engine in  accordance  with  Section  6(c) as
promptly as possible  after the removal of such removed Part.  In addition,  any
replacement Part when  incorporated or installed in or attached to the Engine in
accordance  with Section 6(c) may be owned by a  financially  and  operationally
responsible air carrier subject to such a normal pooling  arrangement;  provided
that  Lessee,  at its expense as promptly  thereafter  as  possible,  either (i)
causes such  replacement Part to become subject to this Lease in accordance with
Section 6(c) by Lessee  acquiring  title  thereto for the benefit of Lessor free
and  clear  of all  Liens  other  than  Permitted  Liens or (ii)  replaces  such
replacement  Part by incorporating or installing in or attaching to the Engine a
further  replacement Part owned by Lessee free and clear of all Liens other than
Permitted Liens and by causing such further  replacement  Part to become subject
hereto in accordance with Section 6(c).

     (e) ALTERATIONS,  MODIFICATIONS AND ADDITIONS.  EXCEPT FOR SUCH ALTERATIONS
AND MODIFICATIONS TO THE ENGINE AS MAY BE REQUIRED FROM TIME TO TIME TO MEET THE
STANDARDS OF THE FAA OR OTHER  GOVERNMENTAL  ENTITY HAVING  JURISDICTION  AND AS
REQUIRED TO CONFORM TO MANUFACTURERS' MANDATORY SERVICE BULLETINS,  LESSEE SHALL
MAKE NO ALTERATIONS,  MODIFICATIONS OR ADDITIONS TO THE ENGINE WITHOUT THE PRIOR
WRITTEN  CONSENT  OF  LESSOR.  Lessee,  at  its  own  expense,  will  make  such
alterations and modifications to the Engine as may be required from time to time
to  meet  the  standards  of  the  FAA  or  other  Governmental   Entity  having


                                       14
<PAGE>

jurisdiction  and as required  to conform to  Manufacturers'  mandatory  service
bulletins,  and shall  notify  Lessor of the nature and schedule for making such
changes and, upon  submission  of the Monthly  Report for the month during which
completion  of the same shall  have  occurred,  of  completion  thereof.  Unless
expressly required by the FAA or Manufacturer's  mandatory service bulletins, no
alteration,  modification or addition shall diminish the value or utility of the
Engine,  or impair the  condition  or  airworthiness  thereof,  below the value,
utility,   condition  and  airworthiness   thereof  immediately  prior  to  such
alteration,  modification or addition (assuming the Engine was then of the value
or utility and in the condition and  airworthiness  required to be maintained by
the terms of this Lease).  All parts incorporated or installed in or attached or
added to the Engine as the result of such  alteration,  modification or addition
shall,  without further act, become subject to this Lease.  Notwithstanding  the
foregoing  sentence  of this  Section  6(e),  so long as no  Default or Event of
Default  shall  have  occurred  and be  continuing,  Lessee may remove any Part;
provided  that (i) such Part is in  addition  to, and not in  replacement  of or
substitution  for, any Part originally  incorporated or installed in or attached
to the  Engine  at the  time  of  delivery  thereof  hereunder  or any  Part  in
replacement  of,  or  substitution  for any such  Part,  (ii)  such  Part is not
required to be  incorporated  or installed in or attached or added to the Engine
pursuant  to the terms of this  Section  6(e) and (iii) such Part can be removed
from the Engine without diminishing or impairing the value,  utility,  condition
or  airworthiness  required to be maintained by the terms of this Lease that the
Engine  would  have had at such time had such  removal  not  occurred.  Upon the
removal by Lessee of any Part as above  provided,  title thereto shall,  without
further act,  vest in Lessee and such Part shall no longer be deemed part of the
Engine from which it was removed. Any Part removed by Lessee in any manner other
than as above  provided  prior to the return of the  Engine to Lessor  hereunder
shall remain the property of Lessor.


      Section 7.  TITLE AND REGISTRATION; LIENS; POSSESSION.

      (a)  TITLE.  Lessee  acknowledges  and agrees  that as between  Lessor and
Lessee  title  to the  Engine  shall  at all  times  be and  remain  solely  and
exclusively  vested in Lessor, and Lessee shall have no right, title or interest
in the  Engine  except the right to use the Engine as  provided  herein.  Lessee
shall from time to time do or cause to be done all acts and things then required
by law or by  practice,  custom or  understanding  or as Lessor  may  reasonably
request to protect,  preserve and perfect Lessor's rights, title and interest in
the  Engine and this  Agreement  in such other  jurisdictions  where  Lessee may
operate the Engine or to the laws of which Lessee or the Engine is or may become
subject.

      (b) LIENS. Lessee will not directly or indirectly create, incur, assume or
suffer to exist any Lien on or with respect to the Engine,  title thereto or any
Part or interest  therein or in this Lease except (i) the  respective  rights of
Lessor and Lessee as herein provided, (ii) the rights of others under agreements
or arrangements to the extent expressly  permitted by the terms of Section 6(d),
(iii) Lessor Liens,  (iv) Liens for Taxes either not yet due or being  contested
in good  faith  (and,  in  respect  of such  contest,  for the  payment of which
adequate  reserves have been  provided) by  appropriate  proceedings  diligently
pursued  so long as such  proceedings  do not  involve  any  danger of the sale,
forfeiture  or loss  of the  Engine  or any  Part or  interest  therein  and (v)
materialmen's,  mechanics',  workmen's,  repairmen's,  employees'  or other like
Liens  arising in the  ordinary  course of  business  for amounts the payment of
which is either not yet delinquent or is being  contested in good faith (and, in
respect of such  contest,  for the payment of which  adequate  reserves or other
adequate  provisions  for  payment by way of  security  or  otherwise  have been
provided)  by  appropriate  proceedings  diligently  pursued  so  long  as  such
proceedings  do not  involve any danger of the sale,  forfeiture  or loss of the
Engine or any Part or interest therein (each of the Liens referred to in clauses
(i) to (v) being herein referred to as "Permitted  Liens").  Lessee will, at its
own  expense,  take such action as may be necessary  duly to discharge  any such
Lien not  excepted  above if the same  shall  arise at any time.  Lessee  hereby
further  agrees that no  mechanics'  or similar Lien for any labor,  services or
materials  supplied  directly by Lessee shall attach to or otherwise  affect the
Engine or any Part and Lessee hereby  irrevocably  waives disclaims and releases
any such Lien.

                                       15
<PAGE>

      (c)  OPERATION.  Lessee shall not operate or locate the Engine,  or suffer
the Engine to be operated or located,  (i) in violation of any  applicable  law,
(ii) in any area excluded  from coverage by any insurance  required by the terms
of Section 9, except in the case of a requisition by a Government  Entity of the
United States where Lessee obtains indemnity in lieu of such insurance from such
Government  Entity  against the risks and in the  amounts  required by Section 9
covering such areas or (iii) in any  recognized or threatened  area of hostility
without   Lessor's   written  consent  and  unless  fully  covered  to  Lessor's
satisfaction by war risk,  confiscation and hijacking  insurance,  or unless the
Engine is operated or used under contract with a Government Entity of the United
States under which contract such Government  Entity assumes direct  liability to
Lessor for any damage, loss,  destruction or failure to return possession of the
Engine at the end of the term of such  contract  and for  injury to  Persons  or
damage to property of others.  Except as otherwise provided herein, Lessee shall
not install or permit the Engine to be  installed  on any  airframe not owned or
leased by Lessee or on any airframe  owned or leased by Lessee unless and for so
long as no Lien will attach to the Engine by virtue or  otherwise as a result of
such installation,  without Lessor's prior written consent.  Provided no Default
or Event of Default  shall  occur and be  continuing,  Lessor  shall not take or
cause or permit to be taken any action inconsistent with Lessee's right of quiet
enjoyment of, or otherwise in any way interfere with or interrupt the continuing
use, operation and possession of the Engine by Lessee.

       (d) POSSESSION. Except as otherwise provided in this Section 7(d), Lessee
shall have no right to sublease the Engine to any Person without having obtained
the prior written consent of Lessor,  which shall not be unreasonably  withheld.
In  addition,  Lessee  will not in any manner  without  Lessor's  prior  written
consent  deliver,  transfer or relinquish  possession  of the Engine;  provided,
that,  so long as no Default or Event of Default is  continuing,  and so long as
the action to be taken shall not deprive  Lessor of its  interest in the Engine,
Lessee may, from time to time, take any of the following actions:

            (i) deliver  possession of the Engine to the  Manufacturer or to any
      organization for testing, service, repair, maintenance or overhaul work or
      for  alterations  or  modifications  in or  additions to the Engine to the
      extent required or permitted by the terms of Section 6(e).

            (ii) install the Engine on any  airframe  owned or leased by Lessee;
      provided  that, no Lien shall attach to any such Engine by virtue of or in
      connection with such  installation,  and the owner,  lessor,  or any party
      having a security  interest in any such airframe grants  reciprocal rights
      to Lessor;  and further  provided that,  Lessee shall maintain any and all
      insurance  required  to be  maintained  upon or in  respect  of the Engine
      hereunder at all times during the Lease Term and until  redelivery  of the
      same in the condition required in Section 10 hereof.

            (iii) transfer  possession of the Engine to any Government Entity of
      the  United  States  pursuant  to a  sublease,  a copy of  which  shall be
      promptly  furnished to Lessor,  provided that such sublease  shall (A) not
      extend  beyond  the end of the  Lease  Term  and  (B)  Lessee  shall  have
      delivered  to  Lessor  signed  copies of a notice  of  assignment  of such
      sublease in favor of Lessor under the Assignment of Claims Act of 1940, as
      amended (31 U.S.C.  Section 3727, 41 U.S.C. Section 15) or any superseding
      or successor  provisions  thereto,  and in compliance  with the applicable
      provisions of 32 C.F.R.  Section 7-103 and 41 C.F.R.  Section  1-30.7,  or
      superseding or successor laws and regulations,  and Lessor may at any time
      when a  Default  or Event  of  Default  shall  have  occurred  and then be
      continuing,  file such  sublease  and an original and three copies of such
      notice of assignment with the proper  contracting and disbursing  officers
      and otherwise comply with all applicable  provisions of 32 C.F.R.  Section
      7-103.8 or any superseding or successor provisions thereto; or

                                       16
<PAGE>

            (iv) with Lessor's prior written consent, which consent shall not be
      unreasonably  withheld,  Sublease the Engine,  for a term  (including  all
      extensions  and  renewals)  which  shall not extend  beyond the end of the
      Lease Term,  to any United States air carrier  certificated  under Section
      41101 of the Federal  Aviation  or any  foreign  air carrier  certificated
      under  Section  41302 of the Federal  Aviation Act. If Lessee is unable to
      obtain  possession  of the  Aircraft  within  thirty  (30) days after such
      sublease shall have been declared to be in default,  free and clear of all
      Liens other than Lessor Liens,  or the Engine shall be deemed to have been
      subject  to an Event of Loss,  the same shall be deemed to  constitute  an
      Event of Loss hereunder.

            Lessee  shall give at least ten (10) days' prior  written  notice to
      the Lessor of any proposed sublease under clause (iv) of this Section 7(d)
      and shall provide  Lessor with a copy of the proposed  Sublease  Agreement
      and other  proposed  documents  to be  executed  in  connection  with such
      sublease.  Such notice shall specify the sublessee,  term of such sublease
      and the domicile of the sublessee. Such notice shall also confirm that the
      proposed  sublease  (a) requires the return of the Engine to Lessee in the
      United  States  promptly (but in no case more than five (5) days after the
      expiration  of the term of the  sublease  and in no event  later  than the
      expiration of the Lease Term, (B) in the case of a proposed sublease to an
      air  carrier  other than a U.S.  certificated  air  carrier,  contains  an
      express  waiver by such sublease of the defense of sovereign  immunity (x)
      in any suit,  act in or  proceeding  arising  out of or  relating  to such
      sublease  and  (y)  of  such   sublessee's   property  from  execution  or
      attachment,  and (C)  provides  that is  shall  terminate  immediately  if
      insurance  shall not be maintained  at all times in  accordance  with this
      Lease.

      Any sublease  permitted  under this  Section 7(d) shall (a) include  terms
substantially   similar  to  those  contained  in  Section  12  and  appropriate
provisions:

                  (1)  requiring  maintenance,  insurance  and  operation of the
            Engine to be in  accordance  with the  relevant  provisions  of this
            Sublease,

                  (2)  requiring the sublessee to keep the Engine free and clear
            of Liens other than Permitted Liens, and

                  (3)  prohibiting   further   transfer  of  the  Engine  to  or
            possession  thereof  by  any  third  Person  (except  for  temporary
            possession  thereof  to  an  authorized  maintenance  performer  for
            purposes of performing maintenance, testing or repairs);

(b) expressly prohibit any further sublease of the Engine by such sublessee; and
(c) be made  expressly  subject and  subordinate  to all the terms of this Lease
including,  without  limitation,  the covenants  contained in this Section 7 and
Lessor's  rights  to  repossession  pursuant  to  Section  14 and to avoid  such
sublease upon a default thereunder or an Event of Default hereunder.

      In  connection  with any  sublease  to an air  carrier  other  than a U.S.
certificated  air carrier  pursuant to clause (iv) of this Section 7(d),  Lessee
shall  obtain,  as a condition to the delivery to the proposed  sublessee of the
Engine,  an opinion from  reputable  counsel in the country of such  sublessee's
domicile  (or, if Lessee  determined  during the term of the  sublease  that the
Engine will be based or  primarily  used in a country  other than the country of
such  sublessee's  domicile,  an  additional  opinion or opinions  of  reputable
counsel in such other  country)  to the effect  that  Lessor's  interest  in the
Engine will be recognized,  the proposed sublease is valid,  binding and (except


                                       17
<PAGE>

as limited by applicable bankruptcy, insolvency,  reorganization,  moratorium or
similar laws  affecting  creditors' or lessors'  rights  generally)  enforceable
against   such   sublessee,   under  the  laws  of  such  country  or  countries
(notwithstanding  any claim or  defense  by  sublessee  or any  other  Person of
sovereign  immunity),  copies of such  opinion or opinions  (x) to be  forwarded
promptly to Lessor,  (y) may, if different opinions are required  hereunder,  be
made by a single counsel  qualified to render  opinions in each such country and
(z) to be in form and substance reasonably satisfactory to Lessee and Lessor.

      No transfer or  relinquishment of possession of the Engine permitted under
this  Section  7(d)  shall in any way  discharge  or  diminish  any of  Lessee's
obligations  hereunder,  or  constitute  a waiver of any of Lessor's  rights and
remedies hereunder. Notwithstanding any transfer or relinquishment of possession
permitted  under  this  Section  7(d),  Lessee  shall  remain  primarily  liable
hereunder  for the  performance  of all of the  terms of this  Lease to the same
extent as if any such transfer or relinquishment of possession had not occurred.

      (e)  IDENTIFICATION  PLATE.  Lessee  shall  maintain  on  the  Engine  the
identification plate installed thereon by Lessor.  Lessee shall promptly replace
any such nameplate that becomes  illegible,  lost,  damaged or destroyed for any
reason.

       (f) REPORTING  REQUIREMENTS.  Commencing with a report furnished  fifteen
(15) days after the end of the calendar month of the Commencement  Date,  Lessee
will furnish to Lessor a Monthly  Report in the form attached  hereto as Exhibit
D.

      (g) INSPECTIONS.  During the Lease Term,  Lessee shall furnish Lessor such
information concerning the location,  condition, use and operation of the Engine
as Lessor may  reasonably  request.  Lessee shall give Lessor  reasonable  prior
notice of the anticipated date of any shop visits,  in order to enable Lessor to
inspect  the Engine  (should it choose to do so) at the time and place such shop
visits  occur.  Lessor shall be entitled to have its  technical  representatives
present  during  any shop  visits.  On  reasonable  notice,  Lessor  and/or  its
authorized agents or representatives  shall have the right to inspect the Engine
and Engine  documentation  (whether in connection with shop visits or otherwise)
and/or make copies of the Engine documentation;  provided, that such inspections
do not  unreasonably  disrupt  Lessee's use and operation of the Engine.  Lessor
shall have no duty to make any such inspection and shall not incur any liability
or obligation by reason of making or not making any such inspection or by reason
of any reports it receives or any reviews it may make of the Engine records.


      Section 8.  LOSS, DESTRUCTION, REQUISITION, ETC.

      (a) EVENT OF LOSS. Except as otherwise set forth herein,  during the Lease
Term, Lessee shall bear the entire risk of loss of or damage to the Engine. Upon
the occurrence of an Event of Loss with respect to the Engine, Lessee shall give
Lessor prompt written notice thereof and shall,  as soon as practical but in any
event within one hundred twenty (120) days after the occurrence of such Event of
Loss, at Lessee's option either (A) convey or cause to be conveyed to Lessor, as
replacement for the Engine,  title to a Replacement Engine free and clear of all
Liens,  other than Permitted Liens, and having a value,  utility,  mod status at
least equal to, and of the same or improved model,  service bulletin status, and
maintenance  status  (i.e.  total  time,   hours/cycles   remaining  until  next
inspection,  overhaul or scheduled  removal)  and in at least as good  operating
condition  as the  Engine,  assuming  the Engine was of the value,  utility  and
remaining  life and in the  condition  and repair  required by the terms  hereof
immediately  prior to the  occurrence of such Event of Loss.  Prior to or at the
time of any such  conveyance,  Lessee,  at its own  expense,  will  promptly (i)
furnish  Lessor  with a bill of sale,  in form  and  substance  satisfactory  to
Lessor, with respect to such Replacement Engine; (ii) cause a supplement hereto,


                                       18
<PAGE>

in form  and  substance  reasonably  satisfactory  to  Lessor,  subjecting  such
Replacement  Engine to this Lease,  to be duly executed by Lessee,  and recorded
pursuant to the Federal  Aviation Act; (iii) furnish Lessor,  with such evidence
of  title to such  Replacement  Engine  and of  compliance  with  the  insurance
provisions  of Section 9 with respect to such  Replacement  Engine as Lessor may
reasonably  request;  (iv) furnish Lessor with an opinion of Lessee's counsel to
the effect  that title to such  Replacement  Engine  has been duly  conveyed  to
Lessor free and clear of all Liens,  encumbrances  and rights of others  (except
Permitted  Liens)  and is duly  leased  hereunder;  (v)  furnish  Lessor  with a
certificate signed by a duly authorized financial officer or executive of Lessee
certifying that Lessee's  representations and warranties set forth in Section 11
are true and  accurate  on and as of said date as though  made on and as of said
date and that upon  consummation  of such  replacement,  no  Default or Event of
Default  will exist  hereunder;  (vi)  furnish  Lessor with such  documents  and
evidence  with  respect to Lessee as Lessor may  reasonably  request in order to
establish the  consummation  of the  transactions  contemplated  by this Section
8(a),  the taking of all  corporate  proceedings  in  connection  therewith  and
compliance  with the  conditions set forth in this Section 8(a), in each case in
form  and  substance  satisfactory  to  Lessor;  (vii)  furnish  Lessor  with  a
certificate of a duly  authorized  officer of Lessee to the effect that no Event
of Default  has  occurred  and is  continuing;  and (viii)  furnish  Lessor with
Uniform Commercial Code financing  statements  covering such Replacement Engine,
or (B) pay to Lessor in  immediately  available  funds the  Engine  Loss  Value,
whereupon  this Lease shall  terminate,  Lessee shall be relieved of all further
obligations  hereunder  except  such as are  expressly  stated  to  survive  the
termination of this Lease and Lessor shall return the Security Deposit to Lessee
as provided in Section 3. Upon full  compliance by Lessee with the terms of this
subparagraph  (a),  the  Engine  shall no longer be subject to the terms of this
Lease and Lessor will cause  Lessor to  transfer to Lessee  title to the Engine,
without recourse or warranty (except that the Engine is free and clear of Lessor
Liens).

      (b) APPLICATION OF PAYMENTS FROM  GOVERNMENTAL  AUTHORITIES.  Any payments
(other than  insurance  proceeds  the  application  of which is provided  for in
Section 9) received at any time by Lessor or Lessee from any  Government  Entity
or  other  Person  with  respect  to  an  Event  of  Loss   resulting  from  the
condemnation,  confiscation,  theft or seizure of, or requisition of title to or
use of, the Engine,  other than a requisition for use by a Government  Entity of
the United States not constituting an Event of Loss, will be applied as follows:
such payments shall be held by the Lessor until (A) replacement of the Engine by
Lessee by a  Replacement  Engine at which  time said  payments  shall be paid to
Lessee;  (B) if Lessee shall have elected not to provide a Replacement Engine as
provided in Section 8(a) said payments shall be applied in reduction of Lessee's
obligation  to pay the Engine Loss Value,  if not already paid by Lessee;  or if
already paid by Lessee,  shall be paid to Lessee and applied to reimburse Lessee
for its payment of such Engine Loss Value; and, (C) the balance, if any, of such
payment remaining thereafter to Lessee.

      (c) REQUISITION FOR USE OF THE ENGINE.  In the event of the requisition of
the Engine for use by a Government  Entity of the United  States during the Term
under  circumstances  not  constituting  an Event of Loss,  Lessee  shall notify
Lessor  of  such  requisition  and all of  Lessee's  obligations  including  the
obligation to pay Rent, shall continue to the same extent as if such requisition
had not  occurred.  Provided  that no  Event  of  Default  has  occurred  and is
continuing,  all  payments  received  by Lessor or Lessee  from such  Government
Entity for the use of the Engine shall be paid over to, or retained by,  Lessee.
All amounts  received by Lessor  during the  continuance  of an Event of Default
shall be held by Lessor as security for and may be applied to the obligations of
Lessee  under this Lease and, at such time as there shall not be  continuing  an
Event of Default, such amounts not previously applied shall be paid to Lessee.

      (d) QUIET ENJOYMENT.  Notwithstanding the provisions of this Section 8, if
(i) Lessee has been deprived of both use and  possession  of the Engine  thereof
solely as a result of the breach by Lessor of its  covenant  of quiet  enjoyment


                                       19
<PAGE>

set forth herein and (ii) Lessee shall have provided  Lessor  written  notice to
the effect that Lessee has been  deprived  of such use and  possession  and that
Lessee  intends to cancel  its  insurance  with  respect to the Engine on a date
specified in such notice  (which date shall not be earlier than thirty (30) days
after the date of Lessor's  receipt of such  notice),  then,  from and after the
date so specified,  but only during the period that Lessee shall  continue to be
deprived of both use and possession of the Engine (the "Suspension Period"), (A)
Lessor shall bear the entire risk of loss or damage  thereof (other than loss or
damage caused by an act or omission of Lessee during the Suspension Period), and
(B) Lessee shall be relieved of its  obligation  to maintain  insurance,  as set
forth in Section 9 hereof,  with  respect  thereto.  In the event of an Event of
Loss of the Engine during any such period,  the Lease shall  terminate and, upon
such  termination  (i) the Engine  shall be deemed to have been  redelivered  to
Lessor in the condition required as of the date on which such deprivation of use
or  possession  first  occurred,  (ii)  Lessee  shall be relieved of all further
obligations  hereunder  except  such as are  expressly  stated  to  survive  the
termination of this Lease and (iii) Lessor shall return the Security  Deposit to
Lessee as provided in Section 3.


     Section 9. INSURANCE.  Except as otherwise set forth in Section 8(d) hereof
in respect of any Suspension Period, Lessee, at its sole cost and expense, shall
maintain  or cause to be  maintained  throughout  the  Lease  Term and until the
return of the Engine to Lessor in such condition as is required under Section 10
hereof with  insurers  of  recognized  responsibility  and good repute and under
policies reasonably  satisfactory to Lessor all such insurance as is required to
be procured  and  maintained  pursuant to this Section 9. Such  insurance  shall
include:

      (a)  LIABILITY.  Lessee,  at its sole cost and expense,  shall maintain or
cause to be maintained throughout the Term and until the return of the Engine to
Lessor  in such  condition  as is  required  under  Section  10  hereof,  public
liability (including, without limitation, aircraft third-party,  baggage, cargo,
contractual and passenger legal liability including war risks),  property damage
liability  insurance  with  respect  to any  aircraft  on which  the  Engine  is
installed and general  airline third party legal liability  (including  products
liability insurance) with insurers of recognized  responsibility and good repute
specializing in aviation insurance in the leading international markets, in form
and in amounts  satisfactory to Lessor at least equal to the greater of (a) [ ]*
Dollars (US$[ ]*) per occurrence  subject to no deductible except deductibles as
to baggage and cargo that are  standard  in the  airline  industry in respect of
carriers  operating in the countries in which Lessee operates and (b) the amount
of such insurance carried by Lessee applicable to other aircraft of similar type
in Lessee's fleet.

      (b) PROPERTY DAMAGE INSURANCE.  Lessee, at its own expense, shall maintain
or cause to be maintained throughout the Lease Term all-risk (including, without
limitation,   fire,  transit  and  extended  coverage)  insurance  and  war-risk
insurance (to the extent available),  with respect to the Engine, whether or not
installed  on an airframe in an amount not less than the Engine Loss Value;  and
such  other  insurance  with  respect  to the  Engine as is carried by Lessee in
respect of other engines of similar make and model in its fleet.

      Notwithstanding anything in the foregoing or in the Lease to the contrary,
no property damage policies shall have a deductible in excess of $[ ]*.

            whatever  reason) of the insurance,  such alteration or cancellation
            shall not be effective as to any Additional  Insured for thirty (30)
            days  (with  respect  to war risk  insurance  seven  (7) days or the
            maximum short or longer period available in the market) after notice
            is given by the underwriters of the insurance;

                  (C) provide that in respect of the interest of Lessor and each
            other Additional Insured in such policies,  such insurance shall not

            Person  and  shall  insure  Lessor's  and the  Additional  Insureds'
            interests,  regardless  of any breach or  violation by Lessee or any

            in such policies;

                  (D)  contain a waiver  by the  insurers  of (x) all  rights of
            subrogation  against  any  Additional  Insured and (y) any rights of

            any of the Additional Insureds; and

            (ii) Any policies  carried in accordance  with Section 9(b) covering
      the Engine and any policies taken out in  substitution  or replacement for
      any such policies shall:

                  (A) insure the interests of, and name as additional  insureds,
            each  Additional  Insured and provide that the  Additional  Insureds
            shall bear no liability for the payment of premiums;

                  (B) be made payable in the United  States to the extent of the
            Engine Loss Value to KGAL as sole "loss payee" (except that proceeds
            with  respect  to loss or damage of less than $[ ]* shall be payable
            to Lessee subject to the last sentence of Section 9(d));

                  (C) provide that if there is any material  adverse  alteration
            or  cancellation  (whether  by Lessee or any  other  Person  and for
            whatever  reason) of the insurance,  such alteration or cancellation
            shall not be effective as to the Additional Insureds for thirty (30)
            days  (with  respect  to war risk  insurance  seven  (7) days or the
            maximum  shorter  or  longer  period  customarily  available  in the
            market) after notice is given by the underwriters of the insurance;

                  (D) provide that in respect of the interest of Lessor and each
            other Additional Insured in such policies,  such insurance shall not
            be  invalidated  by any  action or  inaction  of Lessee or any other
            Person  and  shall  insure  Lessor's  and the  Additional  Insureds'
            interests,  regardless  of any breach or  violation by Lessee or any
            other Person of any warranties, declarations or conditions contained
            in such policies; and

                                       21
<PAGE>

            (iii) All amounts payable under policies  carried in accordance with
      this  Section  9 shall be paid in  immediately  available  Dollars  in the
      United  States.  In the case of a lease or contract with the United States
      or any  Government  Entity  thereof  in  respect  of the  Engine,  a valid
      agreement  duly  assigned to Lessor to indemnify  Lessee  against the same
      risks that Lessee is  required  under  Section 9 to insure  against by the
      United States or such Government Entity in an amount at least equal to the
      Engine Loss Value shall be considered  adequate  insurance with respect to
      the  Engine to the  extent of the  risks and in the  amounts  that are the
      subject of any such agreement to indemnify.

            (iv) All  insurance  maintained  pursuant to this Section 9 shall be
      (A) maintained with recognized  aircraft and aviation insurance  companies
      in the United States or international markets that normally participate in
      aviation   insurance  or  (B)  supported  by  99%  reinsurance  issued  by
      recognized  aircraft and aviation insurance companies in the international
      markets  that  normally  participate  in  aviation  insurance.   Any  such
      reinsurance  shall be with  insurers,  in form and in  amounts  reasonably
      satisfactory to Lessor and shall be subject to "cut through"  endorsements
      or other endorsements or agreements  satisfactory in form and substance to
      Lessor which shall  provide that all payments  under such  reinsurance  in
      respect of losses  shall be paid (x) in the case of  insurance  maintained
      pursuant to Section 9(a) hereof, to the applicable  Additional  Insured or
      (y) in the case of insurance  maintained  pursuant to Section 9(b) hereof,
      to KGAL as sole "loss payee"  (except as provided in Section  9(c)(ii)(B))
      and not to any such primary insurance company.

      (d) APPLICATION OF INSURANCE. All insurance or indemnity payments received
as the result of an Event of Loss with  respect to the Engine will be applied as
follows: such payments shall be held by the insurer until (A) replacement of the
Engine by Lessee by a Replacement  Engine at which time said  payments  shall be
paid to Lessee;  (B) if Lessee shall have  elected not to provide a  Replacement
Engine as provided in Section 8(a) said  payments  shall be paid to Lessor to be
applied in reduction of Lessee's obligation to pay the Engine Loss Value, if not
already paid by Lessee,  or if already  paid by Lessee,  shall be paid to Lessee
and applied to reimburse  Lessee for its payment of such Engine Loss Value;  and
(C) the balance of such payment,  if any, to Lessee. The insurance payments with
respect to any property  damage or loss not  constituting  an Event of Loss with
respect  to the Engine  will be paid to Lessor and  applied by Lessor in payment
(or to reimburse Lessee) for repairs to or replacement of property in accordance
with the terms of Section 6(c) against evidence satisfactory to Lessor that such
repairs  and  replacement  have  been  made,  or to Lessee  if such  repairs  or
replacement have already been paid for by Lessee,  to reimburse Lessee therefor,
and any balance  remaining  after  compliance  with such Section with respect to
such loss shall be paid to Lessee.

Any amount  referred to in this Section 9(d) that is payable to Lessee shall not
be paid to Lessee if at the time of such  payment an Event of Default or Default
shall have occurred and be  continuing,  but shall be held by Lessor as security
for and may be applied to the  obligations  of Lessee  under this Lease and,  at
such time as there shall not be continuing any such Default or Event of Default,
such amount not previously so applied shall be paid to Lessee.

 

                                       22
<PAGE>

    (e) REPORTS.  On or before the Commencement  Date, Lessee will arrange for
appropriate  certification  of the  insurance  required  hereunder to be made by
Lessee's  independent  aviation  insurance  broker  and  furnish  or cause to be
furnished  to Lessor a report  signed by such firm  stating  the opinion of such
firm that the insurance then carried and maintained on the Engine  complies with
the terms  hereof.  Lessee will cause such firm to advise  Lessor and each other
Additional  Insured in writing  promptly  of any  default in the  payment of any
premium,  of any other act or  omission on the part of Lessee of which such firm
has  knowledge  that might  invalidate or render  unenforceable,  in whole or in
part, any insurance on the Engine and of each claim made by Lessee in respect of
the Engine.  Prior to the expiration or on or prior to the  termination  date of
any insurance required  hereunder,  Lessee will provide Lessor with telex or fax
confirmation from Lessee's  independent  aviation  insurance broker that renewed
certificates  of  insurance  evidencing  the  renewal  or  replacement  of  such
insurance and complying  with the provisions of this Lease will be issued on the
termination  date of the prior  certificate.  Within  seven (7) days  after such
renewal, Lessee will furnish brokers' certificates of insurance to Lessor.

       (f) FAILURE TO INSURE. In the event that Lessee shall fail to maintain or
cause to be maintained insurance as herein provided,  Lessor may, at its option,
but without  liability to Lessee for failure to do so,  provide  such  insurance
and, in such event, Lessee shall, upon written demand,  reimburse Lessor for the
cost thereof as Supplemental Rent. At any time while such failure is continuing,
Lessor may  require the Engine to remain at any  airport  until such  failure is
remedied to Lessor's satisfaction.

      (g) ADDITIONAL  INSURANCE.  Nothing  contained in this Lease shall prevent
Lessor or Lessee,  each at its own expense and for its exclusive  benefit,  from
carrying  insurance  covering the Engine in addition to the  insurance  required
under this Section 9 (any such additional  insurance,  "Additional  Insurance");
provided that such Additional  Insurance shall be excess and noncontributory and
shall not  adversely  affect  coverages  under such  insurance  policies  as are
required hereunder.  The insurance payments for any property damage loss covered
by  Additional  Insurance  shall be paid  directly  to the party  carrying  such
Additional Insurance.

      (h) NOTICE OF CLAIMS.  Lessee  shall give Lessor  notice in writing of any
claim or request for payment of an amount in excess of $[ ]* under any  physical
damage insurance policy required to be maintained hereunder promptly (but in any
event within five (5) days) of the filing of such claim or request for payment.


      Section 10.  RETURN OF ENGINE.  The  provisions  of this  Section 10 shall
apply to any  return of the  Engine to Lessor  upon  termination  of this  Lease
(including, without limitation, such return resulting from an Event of Default);
provided, that if this Lease is terminated pursuant to Section 14 and the Engine
is  repossessed  by Lessor,  any action  that is  required to be taken by Lessee
pursuant  to this  Section 10 prior to the  return of the Engine  shall be taken
immediately after the return of such Engine.

      (a) REDELIVERY UPON TERMINATION.  On the date of termination of this Lease
(except as otherwise provided pursuant to Section 8(d)) hereof,  Lessee shall at
its sole  cost and  expense,  return  the  Engine  to  Lessor,  at the  Lessee's
facilities  in  Colorado  Springs,  Colorado  [or at those  of its FAA  approved
maintenance  provider performing the pre-redelivery "C" check] (provided that if
this Lease  shall be  terminated  as a result of a default  by Lessee  under the
Lease the Engine  shall be returned to a point in the United  States  reasonably
requested by Lessor). At the time of return of the Engine to Lessor,  Lessor and
Lessee  shall  execute  a Return  Acceptance  Receipt  in the form of  Exhibit C
hereto.

      (b)  CONDITION  OF ENGINE.  (i) The Engine at the time of return to Lessor
shall have been maintained on an "on-condition" program.

                                       23
<PAGE>

            (ii) Each  Engine  shall have no more cycles or hours since the last
      shop  visit for full  performance  restoration,  as  described  in the CFM
      International,  Inc.  workscope  definitions,  than such  Engine  had when
      delivered.

            (iii) Lessee shall  perform a full and complete  video  borescope on
      each Engine and its modules in accordance  with the Engine  manufacturer's
      maintenance  manual,  with  Lessor or its  representatives  entitled to be
      present.  Lessee will provide evidence to Lessor's  satisfaction that such
      inspection  does not reveal any condition  which would cause the Engine or
      any module to be unserviceable,  beyond serviceable limits, or serviceable
      with  limitations  under the  Engine  manufacturer's  maintenance  manual.
      Lessee will correct any discrepancies (which may be discovered during such
      inspection)  in  accordance  with  the  guidelines  set out by the  Engine
      manufacturer.

            (iv)  The  Engine  shall  have an  exhaust  gas  temperature  margin
      remaining  of 15 degrees or higher and shall,  at a minimum,  meet all the
      requirements  of the maximum  power  assurance run criteria for CFM 56-3B2
      engines.

       (c)  CONDITION  OF  CONTROLLED  COMPONENTS.  Each  life-limited  part  or
component and hour and/or cycle controlled  components of the Engine at the time
of redelivery of the Engine to Lessor shall have  remaining at least 3,000 hours
and/or 3,000 cycles, whichever is more limiting,  between scheduled removals for
overhaul, testing, or disassembly. All components controlled on a calendar basis
shall have remaining at least 12 months before scheduled  removal for testing or
overhaul. Such hour/cycle or calendar controlled components are defined as those
components  controlled under the Maintenance Program.  However, if the component
or part has a check  interval  limit that is less than the above  stated  hours,
cycles or  calendar  time limit  requirement,  the check  interval  limit  shall
prevail.

      (d) ENGINE  DOCUMENTATION.  Lessee  shall return to Lessor at the time the
Engine is returned to Lessor, all of the Engine records  documents,  manuals and
data  provided  to  Lessee by Lessor  prior to, on or after the  Delivery  Date,
updated and  maintained by Lessee  through the date of return of the Engine.  In
addition, Lessee shall also provide Lessor at the time the Engine is returned to
Lessor with all records, documents,  manuals authorizations,  drawings and data,
in each  case in the  English  language,  that  were  developed  or caused to be
developed  by Lessee  and/or  required by the  appropriate  governmental  agency
having jurisdiction  updated and maintained by Lessee for the Engine through the
date of return of the Engine. Any such Engine Documentation not already owned by
Lessor, when delivered to Lessor pursuant to this Section 10(l), shall thereupon
become the  property of Lessor.  In the event Lessor  requires  copies of any of
such Engine  Documentation prior to the return of the Engine to Lessor to enable
Lessor to plan or  accomplish  modifications,  recertification,  sale,  lease or
other  disposition  of or  utilization  of the Engine upon such  return,  Lessee
shall, immediately upon receipt of each such Lessor request, provide to Lessor a
reasonable number of copies of such Engine Documentation  requested by Lessor at
Lessor's sole cost and expense.

      (e) SERVICE BULLETIN KITS. All vendor and manufacturer  provided mandatory
service  bulletin  kits  ordered  and  received by Lessee for the Engine but not
installed  therein shall be returned  with the Engine.  Title to such kits shall
pass to Lessor concurrently with the delivery of the Engine to Lessor.

       (f) NON-U.S.  MANUFACTURED  ITEMS.  Lessee shall provide to Lessor at the
time of the return of the Engine a complete list,  describing by Part number and
name, of all non-United States manufactured equipment,  components and parts, if
any,  installed on the Engine by Lessee  during the Lease Term.  Such list shall
include quantity,  the acquisition price and the manufacturer's name and country
in respect of each such item.

      (g)  LESSEE'S  CONTINUING  OBLIGATIONS.  In the event that Lessee does not
return the Engine to Lessor upon termination of this Lease  (including,  without
limitation, any termination resulting from an Event of Default by Lessee) and in
the condition  required  herein for any reason,  the obligations of Lessee under
this Lease shall continue;  provided,  however,  that such failure to return the
Engine to Lessor in such condition shall not be the result of a breach by Lessor
of its  covenant of quiet  enjoyment  which has  resulted in Lessee  having been
deprived  of use  and  possession  of  the  Engine  immediately  prior  to  such
termination,  in which case the Engine  shall be returned in its then  condition
provided  that,  immediately  prior to such breach by Lessor of its  covenant of
quiet  enjoyment  such Engine  shall have been in such  condition as to meet the
requirements  of  Section 8 hereof but for such  breach.  Such  continuation  of
Lessee's  obligations  shall not be  considered  a renewal  of the terms of this
Lease or of Lessee's rights to use the Engine, an extension of the Lease Term or
a waiver of any  Default or Event of  Default or any right of Lessor  hereunder.
Until  such time as the  Engine is  redelivered  to Lessor as  required  herein,
Lessee  agrees,  during the first  thirty (30) days  following  the  termination
hereof,  to pay Basic Rent with interest at the Post-Default Rate and thereafter
to pay twice the  amount of Basic Rent for each day from such  thirtieth  (30th)
day after the termination hereof until redelivery of the Engine in the condition
required  hereunder  (the monthly Basic Rent payable being prorated based on the
actual number of days in the applicable month).


      Section 11. REPRESENTATIONS, WARRANTIES AND COVENANTS OF LESSEE.
Lessee represents and warrants to, and covenants with Lessor as follows:

      (a) Lessee (i) has been duly  incorporated  and is validly  existing  as a
corporation in good standing  under the laws of the State of Delaware,  (ii) has
full corporate  power and authority and legal right to own its properties and to
carry on its  business as  presently  conducted  and to perform its  obligations

Engine.

      (b) The  execution,  delivery and  performance of this Lease has been duly
authorized by all necessary  corporate  action of Lessee,  and does not and will
not (i) result in the violation of the  provisions  of the charter  documents or
bylaws  of Lessee as in effect  on the date  hereof,  (ii)  require  stockholder
approval or approval or consent of any trustee or holders of any indebtedness of
Lessee, except such approvals which have been obtained and are in full force and
effect,  (iii)  contravene  any  law,  rule or  regulation  or any  order of any
Government  Entity  binding on  Lessee,  and (iv)  conflict  with or result in a
breach of any terms or provisions of or constitute a default under, or result in
or require the creation or imposition of any Lien upon any material  property or
assets of Lessee under, any material  indenture,  mortgage or other agreement or
instrument  as in  effect on the date  hereof  to which  Lessee is a party or by
which  it or any of its  property  is  bound,  or any  applicable  law,  rule or
regulation,  judgment,  order or decree of any Government Entity or court having
jurisdiction over Lessee or any of its properties.

      (c)  No  authorization,   approval,  consent,  license  or  order  of,  or
registration with, or the giving of notice to, or the taking of any other action
in respect of, any  Government  Entity is required for the valid  authorization,
execution,  delivery and performance by Lessee of this Lease or the consummation
of any of the transactions contemplated hereby.

      (d)  Except  for (i) the  filing and  recording  pursuant  to the  Federal
Aviation  Act of  this  Lease,  (ii)  the  filing  of  duly  executed  financing
statements naming Lessee as debtor and Lessor as secured party (and continuation
statements  with respect to such  financing  statements)  with the  Secretary of
State of the State of Colorado and (iii) the retention by Lessor of the original
counterpart  of the Lease to the  extent,  if any,  that the  Lease  constitutes
chattel  paper (as such term is defined  in the  Uniform  Commercial  Code as in
effect in any applicable jurisdiction),  no further action, including any filing


                                       25
<PAGE>

or recording  of any  document  (including  any  financing  statement in respect
thereof  under  Article  9 of the  Uniform  Commercial  Code  of any  applicable
jurisdiction),  is necessary in order to establish and perfect Lessor's title to
the Engine against Lessee and any third parties in any applicable  jurisdictions
in the United States.

      (e) This Lease  constitutes  the legal,  valid and binding  obligation  of
Lessee, enforceable against Lessee in accordance with its terms except as may be
limited by  applicable  bankruptcy,  insolvency,  reorganization,  moratorium or
other similar laws affecting creditors' rights generally and, to the extent that
certain  remedies  require or may require  enforcement by a court of equity,  by
such  principles  of  equity  (regardless  of  whether  such  enforceability  is
considered in a proceeding  at law or in equity) as a court having  jurisdiction
may impose.

      (f) There are no suits or proceedings  pending or, to Lessee's  knowledge,
threatened  in any court or before any  Government  Entity  against or affecting
Lessee that would,  if adversely  determined,  (i) prevent or  adversely  affect
Lessee's ability to perform its obligations  under this Lease or (ii) materially
adversely  affect  the  financial  condition  or  operations  of Lessee  and its
consolidated subsidiaries, taken as a whole.

      (g) The chief  executive  office (as such term is used in Article 9 of the
Uniform  Commercial  Code) of Lessee and the office  where  Lessee will keep its
corporate records concerning the Engine is located in El Paso County,  Colorado.
Lessee will  notify  Lessor  thirty  (30) days in advance of moving  either such
office to another location.

      (h)  There is no Tax,  levy,  impost,  deduction,  charge  or  withholding
imposed  by the State of  Colorado  or any Taxing  Authority  thereof or therein
either (i) on or by virtue of the execution or delivery of this Lease or (ii) on
any payment made or to be made by Lessee under this Lease.

      (i) The obligations of Lessee under this Lease rank at least pari passu in
right of  payment  with all other  unsecured  obligations  of  Lessee,  with the
exception of such obligations as are mandatorily preferred by law.

      (j) Lessee  will give  notice to Lessor  promptly  upon  obtaining  actual
knowledge of any Default or Event of Default; and

      (k) Lessee  acknowledges  that it is the  intention  of Lessor that Lessor
shall be entitled to the  benefits of Title 11 U.S.C.  S-1110 and any similar or
analogous  provisions of any successor  statute ("Section 1110") with respect to
the Engine and this Lease,  and Lessee shall not oppose any motion,  petition or
application  filed by Lessor with any bankruptcy court having  jurisdiction over
Lessee  whereby  Lessor seeks recovery of possession of the Engine under Section
1110 unless Lessee shall have complied with the  requirements of Section 1110 to
be fulfilled in order to entitle  Lessee to continue use and  possession  of the
Engine hereunder.

      (l) Without having  obtained the prior written  consent of Lessor,  Lessee
will not consolidate  with or merge into, or sell or lease in one transaction or
a series of  transactions  all or  substantially  all of its assets to,  another
corporation  or other entity unless such other  corporation or entity is engaged
in the airline  business,  the net worth of the corporation  resulting from such
merger or  consolidation  or  corporation  or other entity to which such sale or
lease is made  would be at least  equal to the net  worth of  Lessee at the date
hereof,  such  corporation or other entity  assumes all of Lessee's  obligations
under this Lease in a manner and by documents  and  agreements  satisfactory  to
Lessor in its sole  discretion,  such  corporation  or other entity  immediately
subsequent  to such  merger,  consolidation,  lease  or  sale is not in  default
hereunder  and  Lessor  receives  an  opinion  satisfactory  to it,  of  counsel
satisfactory to it, as to such assumption and documentation.

                                       26
<PAGE>

      (m) Lessee  shall,  within  fifteen (15) days of the end of each and every
calendar month during the Term, deliver to Lessor a monthly report, in such form
and containing such information as set forth in Exhibit D hereof.

      (n) Lessee shall,  at the end of each calendar  quarter,  have a long term
debt to  equity  ratio of not more than 4:1 as  determined  in  accordance  with
generally accepted  accounting  principles  consistently  applied.  For purposes
hereof, debt shall exclude all off balance sheet financing and operating leases.

      (o) Lessee  shall,  at the end of each calendar  quarter,  have a ratio of
current  assets to current  liabilities  of not less than 1:1 as  determined  in
accordance with generally accepted accounting principles consistently applied.


      Section 12. INDEMNIFICATION.

       (a) GENERAL INDEMNITY AND EXPENSES.  Lessee hereby assumes liability for,
and hereby agrees to, indemnify,  protect,  save and keep harmless Lessor,  KGAL
and their respective affiliates,  agents, officers, directors and employees (the
"Indemnitees"),  and any reference  herein to the  Indemnitee  shall include its
affiliates,  agents, officers,  directors,  employees,  successors and permitted
assigns)  from and  against,  and on  written  demand  to pay,  or to  reimburse
Indemnitee  for the  payment  of, as the case may be,  any and all  liabilities,
obligations,  losses, damages, penalties, claims (including, without limitation,
claims arising out of negligence or involving strict liability in tort),  suits,
actions,  costs, expenses and disbursements,  including without limitation legal
fees and expenses,  of  whatsoever  kind and nature  imposed on,  incurred by or
asserted against  Indemnitees  relating to or arising out of (A) this Lease, any
payments made pursuant  hereto or the exercise of rights or remedies  hereunder,
(B) the  preparation,  negotiation,  execution  and delivery of any  amendments,
modifications  or  waivers  required  by this Lease or  requested  by Lessee (or
resulting  from any requests of Lessee)  hereunder,  (C) the Engine and any Part
thereof, whether or not arising out of the airworthiness, delivery, nondelivery,
lease, presence, storage, modification,  substitution,  replacement, alteration,
maintenance,  inspection,  failure  to  inspect,  repair,  release,  possession,
repossession after an Event of Default,  use,  operation,  condition,  condition
upon return, return, exportation,  importation, transfer or other application or
disposition thereof (including,  in each case and without limitation,  latent or
other defects, whether or not discoverable),  any claim for patent, trademark or
copyright  infringement  arising as a result of or in  connection  with Lessee's
patents,  trademarks,  copyrights,  servicemarks  or logos or those of  Lessee's
advertisers,  sponsors,  and others  whose  designs  and/or  logos appear on the
Engine or any airframe upon which the Engine is installed at any time, any claim
based on strict  or  absolute  liability,  statutory  liability  or tort and any
liability  for any  injury to or death of any person or loss of or damage to any
property including, without limitation, any such arising out of any test flight,
demonstration  flight or ferry  flight of any  aircraft  on which the  Engine is
installed  or performed by Lessee or any entity to which Lessee may have further
subleased  the  Engine  pursuant  to  Section 7 hereof  and (D) any  breach  of,
noncompliance  with or  misrepresentation  made or deemed  made in,  under or in
connection  with  this  Lease  or any  agreement  to  which  Lessee  is a  party
concerning  the  Engine  or any  warranty,  certificate  or  agreement  made  or
delivered in, under or in connection  therewith made or deemed to have been made
by Lessee or anyone claiming by, through or under Lessee;  provided, that Lessee
shall  not be  required  to  indemnify  any  Indemnitee  hereunder  (w)  for any
liability  attributable to acts or events which occur prior to the  Commencement
Date or after  the  Lease  Term or the  return  of the  Engine  to Lessor in the


                                       27
<PAGE>

condition  required  hereunder  whichever  shall occur later,  (x) for liability
resulting solely and directly from acts of gross negligence or misconduct of the
Indemnitee (other than gross negligence or willful misconduct  attributed to the
Indemnitee  solely by reason of its interest in the Engine or any Part), (y) for
any Taxes that  Lessee  has not  agreed to  indemnify  against  pursuant  to the
provisions of Section 12(b) or (z) for any liability  imposed on the  Indemnitee
arising as a result of a disposition of all or any part of Indemnitee's interest
in the Engine,  other than by reason of the  occurrence of a Default or an Event
of Default and further provided that no indemnification  hereunder shall be paid
by Lessee to Indemnitee in respect of any claim arising during any period during
which  Lessee is deprived of use and  possession  of the Engine as a result of a
breach by Lessor of its covenant of quiet enjoyment.

      If any Indemnitee shall have knowledge of any claim or liability  required
to be indemnified  against under this Section 12(a),  the Indemnitee  shall give
prompt written notice thereof to Lessee, but the failure of the Indemnitee so to
notify  Lessee  shall  not  relieve  Lessee  from  any  liability  that it would
otherwise  have to the Indemnitee  hereunder  except to the extent that Lessee's
rights  respecting any defense thereto are  irrevocably and materially  impaired
directly and solely as a result of such failure.

      Lessee  shall be  obligated to the  Indemnitee  under this  Section  12(a)
irrespective of whether the Indemnitee shall also be indemnified with respect to
the same  matter  under any other  agreement,  and the  Indemnitee  may  proceed
directly  against Lessee under this Section 12(a) without first resorting to any
such other rights of indemnification.

      Any payment or indemnity  pursuant to this Section 12(a) shall include the
amount,  if any,  necessary to hold the  Indemnitee  harmless on a net after-tax
basis from all Taxes  required to be paid by such recipient with respect to such
payment or indemnity under laws,  rules or regulations of any Government  Entity
or Taxing  Authority.  If the  Indemnitee is entitled to a permanent tax benefit
(whether  by way of  deduction,  credit or  otherwise)  not taken  into  account
pursuant to the preceding sentence as a result of the matter indemnified against
under this Section  12(a),  the Indemnitee  shall promptly pay to Lessee,  after
such permanent tax benefit is realized but not before Lessee shall have made all
payments  theretofore  due to the  Indemnitee  under  this  Lease  and any other
agreement  in respect of the Engine an amount  that,  after  subtraction  of any
further  tax  savings to which the  Indemnitee  is  entitled  as a result of the
payment thereof, is equal to the amount of such permanent tax benefit; provided,
however,  that the  Indemnitee  shall not be  obligated  to make any  payment to
Lessee  pursuant to this sentence so long as a Default or Event of Default shall
have occurred and be continuing  or any Rent or  Supplemental  Rent then due and
owing shall not have been paid.

      Upon the  indefeasible  payment in full of any  indemnities  due and owing
under  this  Section  12(a),  Lessee  shall be  subrogated  to any  right of the
Indemnitee in respect of the matter against which such indemnity has been given.

      (b)   GENERAL TAX INDEMNITY

            (i) Lessee  agrees that each  payment of Rent or any amount  payable
hereunder shall be free of all withholdings of any nature whatsoever, and in the
event that any withholding is required, Lessee shall pay an additional amount of
Rent such that after the deduction of all amounts  required to be withheld,  the
net amount of Rent that is actually received by Lessor, will equal the amount of
Rent or any such amount payable  hereunder or such other amount, as the case may
be, that would be due absent such withholding,

                                       28
<PAGE>

            (ii) Lessee  hereby  agrees to indemnify  and hold harmless from and
against,  and on written  demand,  to pay or reimburse  each  Indemnitee for the
payment  of, as the case may be,  any and all  Taxes  imposed  upon or  asserted
against the Indemnitee or the Engine,  or any Part thereof or interest  therein,
or this Lease, or the rentals  received under this Lease, by any federal,  state
or local  government  or other  taxing  authority in the United  States,  in any
territory or  possession  thereof or by any foreign  government or any political
subdivision or taxing authority thereof or therein (the foregoing being referred
to herein  individually  as a "Taxing  Authority"  and  collectively  as "Taxing
Authorities") upon or with respect to (a) the acceptance,  rejection,  delivery,
transport, insuring,  registration,  deregistration,  reregistration,  assembly,
possession,  repossession,  operation,  use, presence,  condition,  maintenance,
repair, return, abandonment,  preparation,  installation,  storage,  redelivery,
subleasing,  modification,  rebuilding,  or importation of, or the imposition of
any Lien (other  than a Lessor  Lien) (or the  incurrence  of any  liability  to
refund  or pay over any  amount  as a result  of any Lien  (other  than a Lessor
Lien)) on the Engine or any Part  thereof or interest  therein,  (b) payments of
Basic Rent or  Supplemental  Rent,  (c) the Engine,  or any Part  thereof or any
interest therein or the  applicability of this Lease to the Engine,  or any Part
thereof or any interest therein,  (d) any or all of the documents and agreements
relating to the Engine  contemplated hereby and amendments or supplements hereto
and thereto,  or the execution,  delivery,  filing or recording thereof,  or (e)
otherwise with respect to or in connection with the transactions  effected under
this Lease and the documents and agreements  contemplated  hereby  including the
exercise of remedies hereunder.

            (iii) The  provisions  of Section  12(b)(i) and (ii) shall not apply
to, and Lessee shall have no liability to Lessor or any other person  thereunder
with  respect  to  Taxes  to the  extent  excluded  under  any of the  following
provisions or any combination thereof:

                  (A)  Taxes  imposed  by  any  country,   taxing  authority  or
            governmental  subdivision  thereof or  therein or any  international
            authority  except to the extent  that such Taxes would not have been
            due  (whether or not from the same person on whom they are  actually
            imposed) but for the  transactions  contemplated  by this Agreement,
            provided  that the presence or  activities  of any person other than
            Lessor in any jurisdiction shall not be imputed for purposes of this
            subparagraph (A);

                  (B)  Taxes  (I)  imposed  as a result  of a sale,  assignment,
            transfer or other disposition  (whether voluntary or involuntary) (a
            "Transfer")  (x) by Lessor or any other person (other than Lessee or
            any  affiliate or transferee of or successor to Lessee) of any legal
            or  beneficial  interest  in the Engine or in or arising  under this
            Agreement or (y) of any direct or indirect interest in Lessor or any
            such other person having any such legal or beneficial  interest (any
            event described in (x) or (y) being a "Lessor  Transfer") or (II) to
            the  extent  such  Taxes  exceed the amount of Taxes that would have
            been imposed and indemnified  against by Lessee had there not been a
            Lessor  Transfer,  provided  that the  exclusion  set  forth in this
            subparagraph (B) shall not apply to a Transfer (other than a sale of
            the Engine or any interest  therein)  resulting from the exercise of
            any remedies  provided for in this  Agreement in connection  with an
            Event of Default or an Event of Loss;

                  (C)  Taxes  incurred  in  respect  of  any  period  after  the
            occurrence of any of the following events: (I) the sale or return of
            the Engine or any part thereof or interest therein to the extent the
            Taxes relate solely to such part or interest) in accordance with the
            terms of this Agreement;  (II) the termination of this Agreement and
            the return of the Engine or (III) the sale or other  transfer of the
            Engine and the return of the Engine (or any part thereof or interest
            therein  to the  extent  the  Taxes  relate  solely  to such part or
            interest)  following  a  Total  Loss  with  respect  to the  Engine,


                                       29
<PAGE>

            provided that the exclusion set forth in this subparagraph (C) shall
            not apply to Taxes to the extent such Taxes relate to periods  prior
            to,  or  events   occurring   or   matters   arising   prior  to  or
            simultaneously with, such event;

                  (D) Taxes to the extent imposed as a result of (I) the willful
            misconduct or gross negligence of Lessor,  (II) the breach by Lessor
            of any of its representations,  warranties or covenants contained in
            this Agreement or (III) Lessor's Liens;

                  (E) Taxes either not yet due or being  contested in accordance
            with the provisions of Section 12(d);

                  (F) Taxes on, based on, measured by or with respect to the net
            or gross  income,  or net or gross  receipts,  including any capital
            gains Taxes, minimum Taxes, Taxes on or measured by any items of tax
            preference  and  withholding  Taxes,  including  Taxes imposed under
            Subtitle A of the  Internal  Revenue  Code of 1986,  as amended (the
            "Code")  or  Section  3406 of the Code or any  successor  provisions
            required to be  withheld  from any  payment  under this  Agreement),
            capital, net worth,  franchise,  or conduct of business of Lessor or
            any other  person  (other  than Taxes in the  nature of sales,  use,
            rental,  property,  or  value-added  Taxes)  imposed by any federal,
            state or local government or taxing authority in the United States;

                  (G) Taxes on, based on, measured by or with respect to the net
            or gross  income or net or gross  receipts  (including  any  capital

            preference and withholding Taxes), capital, net worth, franchise, or
            conduct of business of Lessor or any other person  (other than Taxes
            in the nature of sales, use, rental, property, or value-added Taxes)
            imposed by any foreign government, foreign government subdivision or
            other foreign taxing  authority or by any territory or possession of
            the United States, or by any international authority,  provided that
            the exclusion set forth in this  subparagraph  (G) shall not exclude
            such Taxes if and to the  extent  that such Taxes (i) would not have
            been imposed but for the operation, presence or registration in such
            jurisdiction  of the Engine or any part thereof,  or (ii) would have
            been  imposed  solely  as a  result  of (x)  the  presence  in  such
            jurisdiction of a permanent establishment or fixed place of business
            of Lessee,  or any user or person in possession of the Engine or any
            part thereof, (y) the residence,  nationality or place of management
            and  control  of Lessee or any user or person in  possession  of the
            Engine or any part thereof,  (z) the payment from such  jurisdiction
            by Lessee or any user or person in  possession  of the Engine or any

            combination of clauses (i) and (ii);

                  (H) Taxes that would not have been imposed but for any failure
            of Lessor to (x) file proper and timely reports or returns or to pay
            any  Taxes  when  due,  or  (y)  comply   with  any   certification,
            information,  documentation, reporting or other similar requirements
            concerning the nationality,  residence,  identity or connection with
            the jurisdiction imposing such Taxes, if such compliance is required
            to obtain or establish relief or exemption from or reduction in such
            Taxes and Lessor was eligible to comply with such requirement.

                  (I) Taxes imposed under Section 887 of the Code.

       (c)  CALCULATION OF TAX INDEMNITY PAYMENTS

            (i) Any payment  that Lessee shall be required to make to or for the
account  of  the  Indemnitee  with  respect  to  any  Tax  that  is  subject  to
indemnification  under Section 12(b) shall include the amount  necessary to hold
the  Indemnitee  harmless  on a net  after-tax  basis from the net amount of all
Taxes  required  to be paid by the  Indemnitee  as the  result  of such  payment
pursuant to the laws of any Taxing Authority.

            (ii) If Lessor  shall  realize a Tax  benefit as a result of or with
respect to any Taxes paid or indemnified against by Lessee under this Section 12
(whether by way of deduction, credit or otherwise),  Lessor shall pay to Lessee,
promptly  after  realization of such Tax benefit,  an amount that,  prior to the
application of any withholding tax to that payment but after  subtraction of any
further Tax savings Lessor realizes as a benefit,  provided that if any such Tax
benefit is subsequently disallowed,  lost or reduced, Lessee shall, upon written
notice from Lessor,  promptly  repay the amounts paid to the Lessee with respect
to such Tax benefit,  provided  further that Lessor shall not be obligated under
this  Section  12(c)(ii)  to pay Lessee any amounts with respect to Tax benefits
realized  as a result of any Taxes not paid or  indemnified  against  by Lessee.
Notwithstanding anything to the contrary in this Section 12, if, at the time any
payments would otherwise be due to Lessee pursuant to this Section 12(c)(ii), an
Event of Default  shall have occurred and be  continuing,  Lessor shall hold the
amount of such payment as security for the  obligations  of the Lessee to Lessor
under the Lease and at such time as there shall not be continuing any such Event
of Default, shall pay such amount to Lessee. Lessor shall use reasonable efforts
in good faith in filing its Tax returns and in dealing  with taxing  authorities
to seek and to claim any such Tax benefit or savings  and to minimize  the Taxes
payable or indemnifiable by Lessee hereunder.

            (iii) At Lessee's  request,  the computation by Lessor of any amount
payable  by  Lessee  pursuant  to  this  Section  12  shall  be  verified  by an
independent  accounting firm of national reputation selected by Lessor. The fees
of such accountants  shall be paid by Lessee unless such  accountants  determine
that the amount payable to Lessee is at least 25% more, or the amount payable by
Lessee is at least 25% less, than the amount  computed by Lessor,  in which case
such fees shall be payable by Lessor.

      (d)   CONTEST; REPORTS

            (i) If a claim is made in writing  against Lessor  (whether on audit
or otherwise) for any Taxes that Lessee is required to pay or indemnify  against
pursuant to Section  12(b),  Lessor  shall  notify  Lessee in writing  within 30
Business Days of the receipt of such claim, provided that a failure to so notify
will not diminish or relieve  Lessee of any  obligations  under  Section  12(b),
except to the extent Lessee is entitled to contest or to cause Lessor to contest
such  Taxes  and  Lessee's  or  Lessor's  successful  defense  of such  claim is
materially  prejudiced or precluded thereby.  If the amount of the claim exceeds
$[ ]* and if requested by Lessee in  accordance  with this Section  12(d) and in
writing within 30 Business Days after receipt by Lessee of the notice  described
in the  preceding  sentence,  Lessor shall in good faith and with due  diligence
contest (including pursuing all administrative and judicial appeals) in the name
of Lessor or, if permitted by law and requested by Lessee in the name of Lessee,
the   validity,   applicability   or  amount  of  such   Taxes  in   appropriate
administrative or judicial proceedings to be determined by Lessor, provided that
(1) prior to taking  such  action,  Lessee  shall have  agreed to pay Lessor all
out-of-pocket  costs and  expenses  that  Lessor  may incur in  connection  with
contesting such claim, including,  without limitation,  all reasonable legal and
accountant's fees and  disbursements  and costs of  administrative  and judicial
proceedings,   and  the  amount  of  any  interest  or  penalties  that  may  be
attributable  to and  payable  as a result of  contesting  such  claim  (or,  at


                                       31
<PAGE>

Lessor's  request,  Lessee  shall  advance to Lessor funds with which to pay the
foregoing amounts, and Lessor's obligation to contest any Tax shall be suspended
during any period Lessee does not advance  sufficient  funds to pay such amounts
as they accrue or become payable), (2) if such contest is to be initiated by the
payment of, and the  claiming of a refund for such Taxes (and any  interest  and
penalties that also must be paid),  Lessee shall have advanced Lessor sufficient
funds (on an interest-free  basis) to make such payment, (3) no Event of Default
has occurred and is continuing,  (4) the action to be taken will not result in a
material  risk of sale,  forfeiture  or loss of  Lessor's  title  to the  Engine
(unless Lessee provides a bond or other security  satisfactory  to Lessor),  and
(5) at Lessor's  request,  Lessee shall  provide to Lessor a written  opinion in
form  and  substance   satisfactory  to  Lessor  of  independent  legal  counsel
satisfactory  to Lessor  that  there is a  reasonable  basis  for such  contest.
Notwithstanding  that the conditions set forth in clauses (1), (2), (3), (4) and
(5) above may have been satisfied,  Lessor,  after consulting in good faith with
Lessee,  may elect not to pursue  any  contest  or  proceeding  pursuant  to the
preceding sentence or elect to discontinue (by settlement or otherwise) any such
contest or proceeding  commenced  pursuant to the preceding  sentence,  but such
election  shall  constitute  a waiver  by  Lessor  of any  right to  payment  or
indemnification  pursuant to Section 12(b) with respect to the  adjustment  that
was the subject of such proposed contest or proceeding (and any other adjustment
the contest of which is precluded by such failure to contest) and, if Lessee has
theretofore paid or provided Lessor with funds to pay any amount with respect to
such  adjustment,  Lessor shall promptly repay such amount to Lessee.  If Lessor
shall  obtain a refund in  whatever  form of all or any part of any  Taxes  that
Lessee shall have paid or reimbursed to Lessor hereunder, Lessor shall, provided
that no Event of Default shall have occurred and be continuing, pay to Lessee an
amount that is equal to the sum of the amount of such refund or credit, plus any
interest  received on such refund  fairly  attributable  to any Taxes paid by or
with funds  provided by Lessee prior to receipt of such  refund,  reduced by any
Taxes  incurred by Lessor by reason of the receipt or accrual of such refund and
interest and net of any expenses  described in clause (1) of the second sentence
of this Section 12(d) that have not been previously reimbursed, and increased by
any Tax  benefit  realized  by Lessor as a result of any  payment by Lessor made
pursuant  to this  sentence,  provided  further  that,  if,  at the time of such
payment an Event of Default shall have occurred and be continuing,  Lessor shall
hold the amount of such  payment as security  for the  obligations  of Lessee to
Lessor under the Lease,  and at such time as there shall not be  continuing  any
such Event of Default, shall pay such amount to the Lessee. Lessor hereby agrees
that it will inform  Lessee of the time and place of, and Lessor will not object
to Lessee's  presence  at, any  proceeding  conducted  pursuant to this  Section
12(d),  provided that Lessee's  presence also must be allowed by applicable  law
and provided further that the conditions set forth in clauses (1), (2), (3), (4)
and (5) above shall have been, and shall continue to be, satisfied.

            (ii)  Lessee  shall  provide  Lessor  with such  information  in the
possession  of Lessee or  otherwise  reasonably  available  to it as Lessor  may
reasonably  require to enable Lessor to fulfill its tax filing obligations under
this Section 12 and any audit information request arising in connection with the
Taxes  subject  to this  Section  12.  Lessor  shall  provide  Lessee  with such
information in the possession of Lessor or otherwise  reasonably available to it
as Lessee may reasonably  request to fulfill its tax filing  requirements  under
this Section 12 and any audit information request arising in connection with the
Taxes subject to this Section 12. If any report or return is required to be made
with respect to any obligation of Lessee under this Section 12, Lessee will make
such report or return, provided that Lessee shall have no obligation to file any
such return or report if (A) Lessor,  after Lessee's  written request  therefor,
shall have  failed to furnish  Lessee  with such  information  as is  peculiarly
within the control of, or  reasonably  available to Lessor and is necessary  for
the  filing of such  report or  return,  or (B) such  return or report  would or
should have been filed by Lessor even if it had not entered into the Lease.

            (iii)  Lessor  shall  furnish from time to time to Lessee or to such
other  person  as  Lessee  may  designate,  such  returns,  statements  or other
documentation  ("Tax Forms") (including,  without limitation,  if then required,
information  as to the  ultimate  beneficial  owners  of  Lessor  and the  stock
interests in Lessee held actually and constructively by Lessor, if not otherwise
known to  Lessee)  in such  form and with such  substance  as are  necessary  or


                                       32
<PAGE>

appropriate  to enable Lessor or Lessee,  to claim an available  reduction of or
exemption  from Taxes which Lessee may be required to pay or  indemnify  against
hereunder,  provided that Lessee shall have provided Lessor with any information
within the Lessee's control or reasonably  available to Lessee that is necessary
to prepare such return,  statement  or other  documentation.  Any such Tax Forms
shall be provided  promptly after receipt of a written request therefor from the
Lessee.

      (e) PAYMENT.  Unless  otherwise  requested by the appropriate  Indemnitee,
Lessee  shall pay when due any Tax for which it is liable  pursuant  to  Section
12(b) directly to the  appropriate  Taxing  Authority,  or, upon written demand,
shall reimburse the appropriate  Indemnitee for the payment of any such Tax made
by the  Indemnitee.  Within 30 days after the date of each  payment by Lessee of
any  Tax  referred  to in the  preceding  sentence,  Lessee  shall  furnish  the
Indemnitee evidence of payment of such Tax acceptable to the Indemnitee.  Lessee
shall  also  cause to be  furnished,  promptly  upon  request,  such data as the
Indemnitee may reasonably require from Lessee to enable the Indemnitee to comply
with the  requirements of any Taxing Authority in respect of any Tax referred to
in Section 12(b).

      (f) SURVIVAL.  The obligations  contained in this Section 12 shall survive
the  termination  of this Lease,  to the extent they have accrued,  or relate to
events that have occurred,  on or before the date of such termination;  provided
that obligations  arising as a result of the occurrence of a Default or an Event
of Default shall in any event,  without  limiting the  foregoing,  survive until
payment in full and performance of all obligations owing to the Indemnitee under
the  foregoing  agreements  and all  other  agreements  referred  to  herein  or
contemplated   hereby.  The  obligations  of  Lessee  in  respect  of  all  such
indemnities,  obligations,  adjustments  and payments are expressly made for the
benefit of, and shall be enforceable by, the Indemnitee  entitled thereto at the
option of the Indemnitee without declaring this Lease to be in default or taking
any other action hereunder.


      Section 13. ASSIGNMENT; LEASE SUBJECT AND SUBORDINATE.

      (a) SUBLEASE BY LESSEE.  EXCEPT AS OTHERWISE  EXPRESSLY  PROVIDED  HEREIN,
LESSEE SHALL NOT,  WITHOUT HAVING FIRST OBTAINED THE WRITTEN  CONSENT OF LESSOR,
WHICH CONSENT SHALL NOT BE UNREASONABLY  WITHHELD,  ASSIGN OR OTHERWISE TRANSFER
IN ANY MANNER ANY OF ITS RIGHTS OR  INTERESTS  WITH  RESPECT TO THIS LEASE,  THE
ENGINE, OR ANY PART THEREOF.

       (b) ASSIGNMENTS BY LESSOR.  Subject to Lessee's rights hereunder,  Lessor
may at any time and without Lessee's consent sell, assign or transfer its rights
and  interests  hereunder  or with respect to the Engine to a third party and/or
grant a Lien over the  Engine  and the  benefit  of this  Lease to any Person as
security for Lessor's obligations to such Person (each such transferee, assignee
or other Person, an "Assignee").  On request by Lessor,  Lessee will execute all
such documents as Lessor may reasonably require to confirm Lessee's  obligations
under this Lease.  No sale,  assignment  or  transfer  of  Lessor's  interest or
creation of any Lien by Lessor shall adversely  affect Lessee's rights hereunder
or increase Lessee's duties, expenses or the liabilities of Lessee in respect of
any Tax or under any of its  indemnification  obligations  or otherwise.  Lessee
will provide all other  reasonable  assistance and cooperation to Lessor and any
Assignee in connection  with any such sale or assignment or the  perfection  and
maintenance of any Lien granted in connection therewith,  including, at Lessor's
cost, making all necessary filings and registrations. Wherever the term "Lessor"
is  used  in  this  Lease  in  relation  to any of the  provisions  relating  to
disclaimer, title and registration, indemnity and insurance, such terms shall be
construed to include each Assignee, as applicable.

      Section 14. EVENTS OF DEFAULT; REMEDIES.

       (a) EVENTS OF DEFAULT.  The  occurrence  of any of the  following  events
shall  constitute  an  "Event  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

      covenant,  term,  condition or agreement to be performed or observed by it
      hereunder  or under any  instrument,  document or  agreement  furnished by
      Lessee to Lessor,  in connection with the transactions  referred to herein
      or contemplated  hereby, and such failure shall continue  unremedied for a
      period of thirty  (30) days  after  written  notice  thereof  to Lessee or
      thirty (30) days after Lessee,  assuming exercise of reasonable diligence,
      should have known of such  failure;  provided,  however,  such  failure to
      observe  any  covenant,  term,  condition  or  agreement  does  not pose a
      material danger to the respective  rights and interests of Lessor,  Lessor
      in the Engine and the same is of such a nature that it can be cured;  and,
      further  provided that Lessee shall have  commenced  and shall  diligently
      pursue such cure,  Lessee shall have an additional  thirty (30) day period
      within which to cure the same;

            (iv) any  representation or warranty made by Lessee herein or in any

      terms and when due and payable,  the  principal of or interest on any Debt
      the  principal  amount of which exceeds $[ ]* and the maturity of any such
      Debt, in accordance  with the  provisions of any such Debt or any contract
      evidencing,  providing for the creation of or  concerning  such Debt shall
      have been  accelerated  or any event shall have occurred and be continuing
      that would permit any holder or holders of such Debt, any trustee or agent
      acting on behalf of such  holder or  holders  or any other  Persons  so to
      accelerate such maturity;

            (viii)  final  judgment  for the payment of money in excess of $[ ]*
      not fully  covered by insurance (or the  equivalent  in another  currency)
      shall be rendered  against  Lessee and the same shall remain  undischarged

      the free and continued use and exercise thereof curtailed or prevented;

            (xi) except as otherwise permitted pursuant to Section 11(l) hereof,
      Lessee  shall  merge with or into or  consolidate  with or into or convey,
      transfer,  lease or otherwise dispose of (whether in one transaction or in
      a series of transactions)  all or substantially all of its assets (whether
      now owned or hereafter  acquired) to any Person or fifty-one percent (51%)

      (b) REMEDIES.  Upon the occurrence of any Event of Default and at any time
thereafter so long as the same shall be  continuing,  Lessor may, at its option,
declare  this  Lease to be in  default  by  notice  to  Lessee;  and at any time
thereafter,  so long as Lessee shall not have remedied all outstanding Events of
Default  before  Lessor shall have  commenced to exercise its rights or remedies
hereunder,  Lessor may exercise one or more of the following rights and remedies
with  respect to all or any part of the Engine as 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:

            (i) cause Lessee,  upon the written demand of Lessor and at Lessee's
      expense,  to return promptly,  and Lessee shall return promptly (and in no
      event  later  than two days after  such  demand),  all or such part of the
      Engine as Lessor  may  demand,  to Lessor or its order in the  manner  and
      condition required by, and otherwise in accordance with all the provisions
      of,  Section 10 as if the Engine  were  being  returned  at the end of the
      Term, or Lessor,  at its option,  may enter upon the premises where all or
      any part of the Engine located and take immediate possession of and remove
      the same;

                                       35
<PAGE>

            (ii)  hold,  use,  operate,  keep idle or lease to others all or any
      part of the Engine, with or without taking possession thereof as Lessor in
      its sole discretion may determine,  free and clear of any rights of Lessee
      and without  any duty to account to Lessee with  respect to such action or
      inaction or for any proceeds  with respect  thereto,  except that Lessee's
      obligation  to pay Basic Rent for any  periods in respect of the Engine or
      part thereof  accruing after Lessee shall have been deprived of possession
      of such  Engine  or part  thereof  pursuant  to this  Section  14 shall be
      reduced by the net proceeds,  if any,  received by Lessor from leasing the
      Engine or part  thereof  to any  Person  other  than  Lessee  for the same
      periods or any portions thereof;

            (iii)  Lessor may  exercise  any other  right or remedy  that may be
      available  to it under  applicable  law or  proceed by  appropriate  court
      action to enforce the terms hereof or to recover damages for the breach or
      to rescind this Lease;

            (iv) Lessor may terminate this Lease; and/or

            (v) whether or not Lessor shall have exercised,  or shall thereafter
      at any time exercise,  any of its rights under clauses (i), (ii), (iii) or
      (iv) above,  Lessor, by written notice to Lessee specifying a payment date
      not earlier than five (5) Business Days after the date of such notice, may
      terminate this Lease and demand that Lessee pay to Lessor and Lessee shall
      pay to Lessor, on the payment date specified in such notice, as liquidated
      damages  for loss of a bargain  and not as a penalty,  the sum of: (A) any
      unpaid Basic Rent due under this  Agreement for periods ending on or prior
      to the payment date  specified in such notice and any unpaid  Supplemental
      Rent due on or prior to such  payment  date,  plus (B), an amount equal to
      the  aggregate  unpaid  Basic  Rent which  would  otherwise  have  accrued
      hereunder  over the  remainder  of the  Lease  Term  but for the  Event of
      Default,  discounted to present value as of the date specified for payment
      in such  notice,  less  (C),  if  applicable,  for any  period  until  the
      expiration  of the Lease  Term that  Lessor has not been able to Lease the
      Engine but has been able,  in the normal  course of its  operations to use
      the  Engine,  the Basic Rent  payable by Lessee to Lessor for the lease of
      the Engine during any such period of use discounted to present value as of
      the date  specified for payment in such notice.  The amounts  specified in
      such notice shall bear interest at the Post-Default  Rate from the payment
      date  specified  in such  notice  until  payment is made.  In  calculating
      Lessor's damages hereunder upon an Event of Default,  all Basic Rent which
      would have become due during the  remainder  of the Lease Term if an Event
      of Default had not occurred  will be  calculated  on a present value basis
      using a  discounting  rate equal to the rate of interest on United  States
      Treasury Bills having a maturity which will most closely  approximate  the
      period  equal to the  remainder  of the Lease Term,  as quoted in the Wall
      Street Journal on the date of Lessor's notice.

      In addition,  Lessee shall be liable,  except as otherwise provided above,
for any and all  unpaid  Basic  Rent and  Supplemental  Rent then due  hereunder
before or during or after the exercise of any of the foregoing  remedies and for
all legal fees and other costs and expenses  incurred by Lessor by reason of the
occurrence  of any Event of Default or the  exercise of Lessor's  remedies  with
respect  thereto,  including all costs and expenses  incurred in connection with
the return of all the Engine in accordance with Section 10 or this Section 14 or
in storing or maintaining  the Engine or any part thereof or placing the same in
the condition required by Section 10.

                                       36
<PAGE>

      Except as otherwise expressly provided above, no remedy referred to herein
is intended to be exclusive, but each shall be cumulative and in addition to any
other remedy  referred to herein 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 such other remedies;  provided,  that Lessor may recover only once
from each element of damages sustained and, provided further, that the preceding
proviso  shall not be deemed to require proof of damages  actually  sustained in
the case of liquidated damages provided for herein. 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.  To the extent permitted by law, Lessee hereby waives any rights now or
hereafter  conferred  by statute or  otherwise  (A) that may confer any right to
prior notice or judicial  hearing in connection with Lessor's taking  possession
or  disposing of the Engine  including,  without  limitation,  any and all prior
notice and hearing  for any  prejudgment  remedy or remedies  and any such right
that Lessee might otherwise have under applicable law, (B) except as provided in
this Section 14, that impose any  requirements as to the time, place or terms of
lease other disposition or other requirements with respect to the enforcement of
Lessor's  rights  and  remedies   hereunder,   (C)  all  rights  of  redemption,
appraisement,  valuation,  stay,  extension  or  moratorium  now or hereafter in
effect under applicable law that may have the effect of delaying the enforcement
of this Lease or the absolute lease or other  disposition of the Engine,  or (D)
except as otherwise  provided herein,  that may otherwise limit or modify any of
Lessor's  rights  or  remedies  hereunder.  The  failure  or delay of  Lessor in
exercising  any right or remedy  granted it hereunder upon any occurrence of any
of the  contingencies set forth herein shall not constitute a waiver of any such
right or remedy upon the continuation or recurrence of any such contingencies or
similar  contingencies  and any  single or  partial  exercise  hereunder  of any
particular  right or remedy of Lessor shall not exhaust the same or constitute a
waiver of any other right provided herein.

      Notwithstanding  anything  contained in this  Section 14 to the  contrary,
Lessor shall use reasonable efforts to mitigate damages.

      Section 16. GOVERNING LAW AND JURISDICTION.

     (a)  GOVERNING  LAW.  This Lease shall in all  respects be governed by, and
construed  in  accordance  with,  the  internal  laws of the  State of New York,
inclusive of all matters of construction, validity and performance.

     (b) JURISDICTION;  SERVICE OF PROCESS. Lessee and Lessor hereby irrevocably
submit to the jurisdiction of any New York State or federal court sitting in New
York City in any action or proceeding  arising out of or relating to this Lease,
and hereby  irrevocably  agree  that all  claims in  respect  of such  action or
proceeding  may be heard and  determined in such New York State court or, to the
extent  permitted  by law,  in such  federal  court.  Lessee and  Lessor  hereby
irrevocably waive, to the fullest extent they may effectively do so, the defense
of an inconvenient forum to the maintenance of such action or proceeding. Lessee
hereby irrevocably  appoints CT Corporation  System,  with an office on the date
hereof at 1633 Broadway, New York, New York 10019, and Lessor hereby irrevocably
appoints  CT  Corporation  System,  with an  office  on the date  hereof at 1633
Broadway,  New York, New York 10019 (the "Process  Agent"),  as their respective
agents to receive on their  behalf  and in  respect of their  proper  service of
copies of the summons and  complaint and any other process that may be served in
any such action or proceeding. Such service may be made by mailing or delivering
a copy of such process to Lessee or Lessor, as the case may be, in care of their
respective Process Agents at such Process Agent's above address,  and Lessee and
Lessor hereby  irrevocably  authorize and direct their respective Process Agents
to accept such service on their  behalf.  As an  alternative  method of service,
Lessee and Lessor also irrevocably consent to the service of any and all process
in any such action or proceeding by the mailing of copies of such process to the
address  specified in Section 15. Lessee and Lessor agree that a final  judgment
in any such  action or  proceeding  shall be  conclusive  and may be enforced in
other  jurisdictions  by suit on the judgment or in any other manner provided by
law.  Nothing  in this  Section  16(b)  shall  affect  the  right of any  Person
(including  Lessor) to serve legal process in any other manner  permitted by law
or affect the right of any other party to bring any action or proceeding against
Lessee  or  Lessor,  or  their  respective  properties  in the  courts  of other
jurisdictions.  Lessee AND Lessor  HEREBY  WAIVE  TRIAL BY JURY IN ANY  JUDICIAL
PROCEEDING  TO WHICH THEY ARE PARTIES  INVOLVING,  DIRECTLY OR  INDIRECTLY,  ANY
MATTER ARISING OUT OF OR RELATING TO THIS LEASE.

                                       38
<PAGE>

      (c)  WAIVER OF  IMMUNITY.  To the  extent  that  Lessor  or Lessee  has or
hereafter  may  acquire  any  sovereign  immunity,   Lessor  and  Lessee  hereby
irrevocably waive such immunity in respect of their respective obligations under
this Lease and all other documents and agreements relating to the Engine and the
transactions referred to or contemplated herein.


      Section 17.  MISCELLANEOUS.

       (a) ENTIRE AGREEMENT. This Lease constitutes the entire agreement between
the parties  concerning the subject  matter hereof,  and supersedes all previous
proposals, agreements,  understandings,  negotiations and other written and oral
communications  in relation  hereto.  NO TERM OR  PROVISION OF THIS LEASE MAY BE
CHANGED,  WAIVED,  DISCHARGED OR  TERMINATED,  EXCEPT (i) WITH THE PRIOR WRITTEN
CONSENT  OF  LESSOR  AND  (ii) BY AN  INSTRUMENT  IN  WRITING  SIGNED  BY A DULY
AUTHORIZED  REPRESENTATIVE  OF THE PARTY  AGAINST WHICH THE  ENFORCEMENT  OF THE
CHANGE,  WAIVER,  DISCHARGE OR  TERMINATION  IS SOUGHT.  Nothing herein shall be
construed as  conveying to Lessee any right,  title or interest in the Engine or
any Part except as Lessee under this Lease.

       (b) ENGLISH LANGUAGE. All notices, communications,  reports, opinions and
other documents given under this Lease shall be in the English language.

      (c)  LESSOR'S  RIGHT TO PERFORM  FOR LESSEE.  If Lessee  fails to make any
payment of Rent or  Supplemental  Rent  required to be made by it  hereunder  or
fails to perform or comply with any of its agreements  contained herein,  Lessor
may itself make such payment or perform or comply with such  agreement,  and the
amount of such  payment  and the amount of any  expenses  of Lessor  incurred in
connection  with such  payment or the  performance  of or  compliance  with such
agreement,  as the case may be,  shall be deemed  Supplemental  Rent  payable by
Lessee upon demand;  provided,  however,  that no such payment,  performance  or
compliance  by Lessor shall (i) be deemed to have  satisfied  the  obligation of
Lessee to make such payment or to perform or comply with such agreement,  as the
case may be, unless and until Lessee shall have paid all such  Supplemental Rent
payable  pursuant to this  section by reason of such failure or (ii) be deemed a
waiver of Lessor's rights and remedies against Lessee hereunder.

      (d)  APPLICATION  OF PAYMENTS  DURING  EXISTENCE  OF  DEFAULT.  Any amount
referred to herein that is payable to Lessee shall not be paid to Lessee,  or if
it has been previously paid directly to Lessee, shall not be retained by Lessee,
if at the time of such payment a Default or Event of Default shall have occurred
and be  continuing,  but shall be paid to and held by Lessor as security for and
may be applied to the  obligations  of Lessee under this Lease and, at such time
as Lessor shall receive  evidence in form and substance  satisfactory to it that
there is not continuing  any such Default or Event of Default,  all such amounts
in excess of amounts so paid on obligations of Lessee shall be paid to Lessee.

      (e) EXPENSES.  Lessee agrees to reimburse  Lessor,  for its  out-of-pocket
costs and expenses,  including  attorney's fees, incurred in connection with any
amendments,  modifications  or waivers  required by this Lease or  requested  by
Lessee (or resulting from any requests of Lessee) hereunder.



                                       39
<PAGE>

      (f) FURTHER ASSURANCES.  Lessee will promptly and duly execute and deliver
to Lessor such further  documents and assurances and take such further action as
Lessor 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 Lessor
hereunder, including, without limitation, if requested by Lessor, at the expense
of Lessee,  the execution and delivery of supplements or amendments  hereto,  in
recordable  form,  subjecting  to this  Lease  any  Replacement  Engine  and the
recording or filing of  counterparts  hereof,  and all such other  documents and
instruments,  in accordance  with the laws of such  jurisdictions  as Lessor may
from time to time deem advisable.

       (g) JUDGMENT  CURRENCY.  The obligations of Lessee in respect of any sum
due  from it to  Lessor  hereunder  shall,  notwithstanding  any  judgment  in a
currency other than Dollars, be discharged only to the extent that Lessor may in
accordance with normal banking procedures purchase, or cause to be purchased for
its account  Dollars with such other  currency;  if the Dollars so purchased are
less than the sum originally due in Dollars,  Lessee agrees to indemnify  Lessor
against such loss, and if the Dollars so purchased exceed the sum originally due
to Lessor in Dollars, Lessor agrees to remit to Lessee such excess.

      (h)  INVALIDITY  OF ANY  PROVISION.  Any  provision  of this Lease 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.  To the fullest extent
permitted by  applicable  law,  Lessee  hereby  waives any provision of law that
renders any provision hereof prohibited or unenforceable in any respect.

      (i) CHANGES IN LAW. If there shall be any change (or such change  shall be
enacted  or made by  notice  or  otherwise  and  shall be  scheduled  to  become
thereafter  effective)  in the laws or treaties of the United  States that has a
material adverse effect on the validity, legality,  perfection or enforceability
of  Lessor's  rights or  interest  in the Engine or this Lease or the  validity,
legality,  perfection or enforceability of this Lease, Lessor may terminate this
Agreement,  whereupon  Lessee shall promptly  return the Engine to Lessor or its
designee in the condition required hereunder.

       (j) HEADINGS.  All section and paragraph headings and captions are purely
for convenience of reference only and shall not modify, define, expand, limit or
otherwise affect any of the terms or provisions hereof and all references herein
to numbered sections, unless otherwise indicated, are to sections of this Lease.

      (k)  CONSENT.  Whenever  in this Lease,  the consent  (whether or not, in
writing)  of either  Lessor or Lessee is  required,  such  consent  shall not be
unreasonably withheld or delayed.

      (l) THIRD PARTY  BENEFICIARIES.  Lessee recognizes that this Lease confers
certain  rights  and  interests  on the  Indemnitees.  Notwithstanding  that the
Indemnitees  are not parties to this Lease,  the  Indemnitees are intended third
party  beneficiaries of such rights and interests and Lessor hereby acknowledges
that the Indemnitees may enforce such rights and interests directly,  as if they
were parties to this Lease.

      (m)  COUNTERPARTS.  This Lease may be executed in any number of  identical
counterparts,  all of  which  together  will be  deemed  to be one and the  same
instrument.  Delivery of an executed counterpart of this Lease by facsimile will
be deemed effective as delivery of an originally executed counterpart. Any party
delivering an executed  counterpart of this Lease by facsimile will also deliver
an originally executed counterpart; provided the failure of any party to deliver
an originally executed counterpart of this Lease will not affect the validity or
effectiveness of this Lease.

                           Lease,  and shall  look  solely to the New Lessor for
                           reimbursement   of  the  Security   Deposit  and  the
                           Maintenance  Reserves  in  accordance  with the terms
                           thereof.

     Section 3. CLAIMS ARISING PRIOR TO THE CLOSING DATE. (a) Without  prejudice
to the  rights of the New Lessor  under the  Amended  and  Restated  Lease,  the
Sublessor and the Sublessee  agree that each of them,  and each  Indemnitee  (as
defined in the Sublease) shall have, pursuant to this Section 3, the same rights
and  remedies  as they would  have had under the  Sublease  (including,  without
limitation,  Sublessee's indemnities under Section 12 of the Sublease),  without
regard to any amendment  thereto  effected by the Amended and Restated Lease, in
respect of any losses, liabilities indemnities or claims suffered or incurred or
brought against,  or payment due to, the other to the extent attributable to any
period ending prior to the Closing Date to the same extent as provided for under
the Sublease as in effect prior to the execution and delivery of the Amended and
Restated Lease.

     (b) The Sublessee hereby acknowledges and agrees that all of the covenants,
undertakings, obligations and liabilities of the Sublessor under Section 6(b) of
the Sublease  have been fully  performed  and that it has no claims  against any
Maintenance Reserves or the Sublessor in respect thereof.

     Section 4. MAINTENANCE RESERVES; SECURITY DEPOSIT. (a) On the Closing Date,
the New Lessor has agreed to pay the purchase price to the Original Lessor,  and
such purchase price reflects a reduction in respect of the amount of Maintenance
Reserves  and  Security  Deposit held on the Closing Date by or on behalf of the
Sublessor. From and after the Closing Date, the Sublessee shall look only to the
New Lessor for the  reimbursement  of the Security  Deposit and any  Maintenance
Reserves in accordance  with the  provisions of the Amended and Restated  Lease.
For the  avoidance  of doubt,  the  Sublessee  confirms,  for the benefit of the
Sublessor  and the New Lessor,  that the amounts being held by the Sublessor for
Maintenance Reserves are as set forth below:

                  Airframe C-7 or D-check            $[     ]*

                  Engine MSN 720890

                           Shop Visit Portion        $[     ]*

                           LLP Portion               $[     ]*

                  Engine MSN 721734

                           Shop Visit Portion        $[    ]*

                           LLP Portion               $[    ]*

          The  amount of the  Security  Deposit  being  held in  respect  of the
          Aircraft is $[ ]*

     (b) From  and  after  the  Closing  Date,  all  payments  to be made by the
Sublessee in respect of Maintenance Reserves shall be paid to the New Lessor and
not to the Sublessor, and the Sublessor shall not make any claim thereon or have
any right  therein.  From and after the Closing Date,  the New Lessor shall have
the right to receive all  Maintenance  Reserve  payments that have accrued since
the immediately  preceding date on which Maintenance  Reserves were due pursuant
to Section 6(b) of the Sublease and the Sublessee  shall pay all such amounts to
the New  Lessor on the due date  therefor  in  accordance  with the terms of the
Amended and Restated Lease.

                                       4

     Section 5.  CONDITIONS  PRECEDENT.  On or prior to the  Closing  Date,  the
Sublessee  shall  deliver  to the New  Lessor  and  Sublessor  (i) an opinion of
counsel in form and substance  reasonably  satisfactory to the New Lessor to the
effect,  among other  things,  that this  Novation  and the Amended and Restated
Lease have been duly  authorized  by the Sublessee  and  constitute  enforceable
obligations  of the  Sublessee and (ii) a  certificate  of insurance  evidencing
compliance by the Sublessee  with the provisions of Section 9 of the Amended and
Restated Lease and Section 6 of this Novation.

     Section 6. INSURANCE.  (a) Required  Insurance.  From and after the Closing
Date and until the  earlier of April 30,  1999 or the date of the next "D" check
(or its equivalent) on the Aircraft,  Sublessee shall maintain public  liability
(including,   without  limitation,   aircraft   third-party,   baggage,   cargo,
contractual and passenger legal liability including war risks),  property damage
liability insurance with respect to the Aircraft and general airline third party
legal liability insurance (including products liability insurance) with insurers
of recognized  responsibility and good repute specializing in aviation insurance
in the leading international  markets, in amounts at least equal to [ ]* Dollars
(U.S. $[ ]*) per occurrence  subject to no deductible  except  deductibles as to
baggage  and cargo  that are  standard  in the  airline  industry  in respect of
carriers  operating  in the  countries  in which the  operator  of the  Aircraft
operates.

     (b) TERMS OF INSURANCE.  Any policies  carried in  accordance  with Section
6(a) hereof and any policies taken out in  substitution  or replacement  for any
such policies shall (i) insure the interests of and name as additional insureds,
each of the Original  Lessor,  Amerilease  and  Sublessor  and their  respective
officers,  directors,  employees  and agents  (the  "Additional  Insureds")  and
provide  that the  Additional  Insureds  bear no  liability  for the  payment of
premiums;  (ii)  provide  that the  coverages  afforded by such  policies to the
Additional Insureds shall not be invalidated by any act or omission of any named
insured or other person which results in a violation of the terms, conditions or
warranties  of the  policies,  provided  that the named insured or the person so
protected has not caused,  contributed to or knowingly  condoned the said act or
omission; (iii) provide that if there is any cancellation of the insurance, such
cancellation shall not be effective as to any Additional Insured for thirty (30)
days (with respect to war risk  insurance,  seven (7) days or such lesser period
as may be customarily  available) after the underwriters of such insurance issue
written notice of such cancellation or alteration;  (iv) contain a waiver by the
insurers of (A) all rights of subrogation  against any and all of the Additional
Insureds  and (B) and rights of set-off,  counterclaim  or any other  deductions
whether by attachment or otherwise,  which they may have against any  Additional
Insured;  and (v) be primary and without  right of  contribution  from any other
insurance carried by any of the Additional Insureds, and shall expressly provide
that all of the provisions thereof (except limits of liability) shall operate in
the same  manner as if there were a separate  policy  covering  each  Additional

     Section 3. CLAIMS ARISING PRIOR TO THE CLOSING DATE. (a) Without  prejudice
to the rights of the New Lessor under the Amended and Restated Engine Lease, the
Original  Lessor and the Lessee agree that each of them, and each Indemnitee (as
defined in the Engine  Lease)  shall have,  pursuant to this Section 3, the same
rights and  remedies as they would have had under the Engine  Lease  (including,
without limitation,  Lessee's indemnities under Section 12 of the Engine Lease),
without  regard to any  amendment  thereto  effected by the Amended and Restated
Engine  Lease,  in  respect of any  losses,  liabilities  indemnities  or claims
suffered  or incurred  or brought  against,  or payment due to, the other to the
extent  attributable  to any period ending prior to the Closing Date to the same
extent  as  provided  for  under  the  Engine  Lease as in  effect  prior to the
execution and delivery of the Amended and Restated Engine Lease.

     (b) The Lessee hereby  acknowledges  and agrees that all of the  covenants,
undertakings,  obligations  and liabilities of the Original Lessor under Section

against any Engine Reserves or the Original Lessor in respect thereof.

     Section 4. ENGINE RESERVES;  SECURITY DEPOSIT. (a) On the Closing Date, the
New Lessor has agreed to pay the purchase price to the Original Lessor, and such
purchase price reflects a reduction in respect of the amount of Engine  Reserves
and  Security  Deposit  held on the Closing Date by or on behalf of the Original
Lessor.  From and after the Closing Date,  the Lessee shall look only to the New
Lessor for the  reimbursement of the Security Deposit and any Engine Reserves in
accordance with the provisions of the Amended and Restated Engine Lease. For the
avoidance of doubt, the Lessee confirms,  for the benefit of the Original Lessor
and the New  Lessor,  that the  amounts  being held by the  Original  Lessor for
Engine Reserves are as set forth below:

                     Engine MSN 721150

                               Shop Visit Portion             $[    ]*

                               LLP Portion                    $[    ]*


     The amount of the Security  Deposit  being held in respect of the Engine is
     $[ ]*.

     (b) From and after the Closing Date,  all payments to be made by the Lessee
in  respect  of Engine  Reserves  shall be paid to the New Lessor and not to the
Original  Lessor,  and the Original  Lessor shall not make any claim  thereon or
have any right  therein.  From and after the Closing Date,  the New Lessor shall
have the right to receive all Engine  Reserve  payments  that have accrued since
the  immediately  preceding  date on which Engine  Reserves were due pursuant to
Section  6(b) of the Engine  Lease and the Lessee  shall pay all such amounts to
the New  Lessor on the due date  therefor  in  accordance  with the terms of the
Amended and Restated Engine Lease.

     Section 5.  CONDITIONS  PRECEDENT.  On or prior to the  Closing  Date,  the
Lessee  shall  deliver to the New Lessor and  Original  Lessor(i)  an opinion of
counsel in form and substance  reasonably  satisfactory to the New Lessor to the
effect,  among other  things,  that this  Novation  and the Amended and Restated
Engine Lease have been duly authorized by the Lessee and constitute  enforceable
obligations  of the  Lessee  and  (ii) a  certificate  of  insurance  evidencing
compliance  by the Lessee  with the  provisions  of Section 9 of the Amended and
Restated Engine Lease and Section 6 of this Novation.

set-off,   counterclaim  or  any  other  deductions  whether  by  attachment  or
otherwise,  which  they may have  against  any  Additional  Insured;  and (v) be
primary and without right of contribution  from any other  insurance  carried by
any of the  Additional  Insureds,  and shall  expressly  provide that all of the
provisions thereof (except limits of liability) shall operate in the same manner
as if there  were a separate  policy  covering  each  Additional  Insured;  with
substantially  the same  endorsements  (insofar  as the same apply to  liability
coverage) as are currently in effect with respect to the Engine.

     (c)  INSURANCE  CERTIFICATES. On or before the Closing  Date,  and promptly
after each renewal or  replacement  of the  policies of  insurance  covering the
Aircraft,  Lessee shall cause to be  furnished  to Original  Lessor an insurance
certificate  of  independent  aircraft  insurance  brokers  evidencing  that the
insurance  then  carried and  maintained  on any aircraft on which the Engine is
installed complies with the terms hereof. Lessee shall cause such firm to advise
the Additional Insureds in writing promptly of any default in the payment of any
premium,  of any other act or  omission on the part of Lessee of which such firm
has  knowledge  that might  invalidate or render  unenforceable,  in whole or in
part, any insurance provided pursuant to Section 6(a).
