                 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1. BASIS OF PRESENTATION

     The accompanying unaudited consolidated financial statements have been
prepared  by the  Company  pursuant  to the  rules  of the  Securities  and
Exchange Commission ("SEC") and, in the opinion of the Company, include all
adjustments, consisting only of normal recurring adjustments, necessary for
a fair presentation of financial  position,  results of operations and cash
flows.  Certain information and footnote  disclosures  normally included in
financial   statements  prepared  in  accordance  with  generally  accepted
accounting principles have been condensed or omitted pursuant to SEC rules.
The  operating  results for the three and nine months ended  September  30,
1998 are not  necessarily  indicative of the results to be expected for the
entire year ended December 31, 1998. These financial  statements  should be
read in conjunction  with the consolidated  financial  statements and notes
thereto for the year ended December 31, 1997 included in the Company's 1997
Annual Report to Stockholders.

NOTE 2. EARNINGS PER SHARE

     Basic  earnings per share were  computed by dividing net income by the
weighted average common shares  outstanding  during the periods  presented.
Diluted  earnings  per share were  computed by  dividing  net income by the
weighted average common shares and potential common shares outstanding. The
Company adopted Financial Accounting Standards Board SFAS No. 128, Earnings
per Share, effective December 15, 1997. As a result, all earnings per share
information  for  prior  periods  have  been  restated  to  conform  to the
requirements of SFAS No. 128.

                                                   =============  =============

NOTE 4. INCOME TAXES

     In the quarter and nine month period  ended  September  30, 1998,  the
Company recorded income tax provisions of $ 34.0 million and $90.4 million,
respectively,  based on an estimated annual effective tax rate of 36.0%. In
the  comparable  periods of 1997,  the Company  recorded no  provision  for
income taxes, other than alternative minimum taxes, principally as a result
of utilization of net operating loss carryforwards. As a result of numerous
factors, including, but not limited to the Company's recent earnings trends
and the size of its contractual  backlog,  the Company  determined that its
net deferred tax asset was more likely than not to be realized, and, in the
quarter  ending  September  30, 1997,  released its deferred tax  valuation
allowance, totaling $94.2 million. Of this amount, $29.4 million related to
the  exercise of stock  options  and was  credited  to  additional  paid-in
capital and $64.8 million was recorded as a one-time,  non-cash  income tax
benefit.

NOTE 5. COMMITMENTS AND CONTINGENCIES

     In the normal  course of business,  lawsuits,  claims and  proceedings
have been or may be instituted or asserted  against the Company relating to
various  matters,  including  products  liability.  Although the outcome of
litigation cannot be predicted with certainty and some lawsuits,  claims or
proceedings  may be disposed of unfavorably to the Company,  management has
made provision for all known probable losses related to lawsuits and claims
and  believes  that the  disposition  of all  matters  which are pending or
asserted  will  not  have  a  material  adverse  effect  on  the  financial
statements of the Company.

     The Company is involved in tax audits by the Internal  Revenue Service
covering the years 1990 through 1994. The revenue  agent's  reports include
several  proposed  adjustments   involving  the  deductibility  of  certain
compensation expense,  items relating to the initial  capitalization of the
Company,  the allocation of the original purchase price for the acquisition
by the Company of the  Gulfstream  business,  including  the  treatment  of
advance  payments with respect to the cost of aircraft that were in backlog
at the time of the acquisition,  and the amortization of amounts  allocated
to intangible assets. The Company believes that the ultimate  resolution of
these  issues  will not have a  material  adverse  effect on its  financial
statements  because  the  financial  statements  already  reflect  what the
Company currently believes is the expected loss of benefit arising from the
resolution of these issues.

     The  Company is  currently  engaged in the  monitoring  and cleanup of
certain  ground water at its Savannah  facility  under the oversight of the
Georgia Department of Natural Resources. Expenses incurred for cleanup have
not  been   significant.   Liabilities  are  recorded  when   environmental
assessments  and/or  remedial  efforts  are  probable  and the costs can be
reasonably  estimated.  The Company  believes the remainder of the Savannah
facility,  as well as other  Gulfstream  properties,  are  being  carefully
monitored and are in substantial compliance with current federal, state and
local environmental regulations.  The Company believes the liabilities,  if
any, that will result from the above environmental  matters will not have a
material adverse effect on its financial statements.

NOTE 6. COMMON STOCK REPURCHASES

     During January 1998, the Company  announced a program to repurchase up
to $200 million of its common stock.  As of September 30, 1998, the Company
had repurchased  approximately  5.5 million shares,  at an average price of
$35.81 per share, for an aggregate amount of approximately  $198.5 million.
The repurchase was funded from the Company's available cash.

NOTE 7. BUSINESS ACQUISITION

     On August 19,  1998,  the Company  acquired  K-C  Aviation,  Inc.  for
approximately $250 million,  including acquisition costs. K-C Aviation is a
leading provider of business aviation services and the largest  independent
completion  center for business  aircraft in North America.  In addition to
custom  aircraft  interiors,  K-C  Aviation  is the second  largest  engine
service center in the United States and also offers  maintenance  services,
spares,  auxiliary power unit service,  avionics retrofit,  non-destructive
testing and component overhaul.

     The purchase of K-C Aviation,  Inc. was funded primarily from existing
cash  balances,  and due to the timing of the  closing of the  transaction,
also from the revolving credit facility.

     The acquisition has been accounted for as a purchase, and accordingly,
the  operating  results of K-C Aviation have been included in the Company's
consolidated  financial  statements  since  the  date of  acquisition.  The
purchase  price  exceeded  the  fair  value  of  net  assets   acquired  by
approximately  $178 million,  which is being  amortized on a  straight-line
basis over 40 years. Allocations of the purchase price have been determined
based upon preliminary  estimates of value,  and therefore,  are subject to
change as asset appraisals are finalized. As refinements are made, goodwill
and any other appropriate accounts will be adjusted accordingly.

     The  following  unaudited  pro forma  summary  presents  the  combined
results  of  operations  of  the  Company  and  K-C  Aviation,  as  if  the
acquisition  had occurred at the beginning of fiscal 1998 and 1997. The pro
forma   amounts  give  effect  to  certain   adjustments,   including   the
amortization  of goodwill,  reduced  interest  income from cash utilized to
complete the acquisition and the related income tax effects.  The pro forma
consolidated  results do not purport to be indicative of results that would
have occurred had the acquisitions been in effect for the period presented,
nor do they purport to be  indicative  of the results that will be obtained
in the future.

NOTE 8. CHANGE IN ACCOUNTING PRINCIPLES

     Effective  January 1, 1998, the Company adopted Statement of Financial
Accounting  Standards  No.  130,  Reporting   Comprehensive   Income.  This
Statement  requires  disclosure of total nonowner  changes in stockholders'
equity,  which is defined as net income plus certain direct  adjustments to
stockholders' equity such as pension liability  adjustments.  For the three
and  nine  month  periods  of  1998  and  1997,  the  Company  had no  such
adjustments.

NOTE 9. NEW ACCOUNTING STANDARD

     In June 1997, the Financial Accounting Standards Board issued SFAS No.
131,  Disclosures about Segments of an Enterprise and Related  Information,
which is effective no later than for the  Company's  1998 fiscal  year-end.
Management  believes  that the adoption of this  statement  will not have a
material effect on the Company's consolidated financial statements.

     Net  Revenues.  Total net  revenues  increased by $162.2  million,  or
35.0%,  to $626.2  million in the third quarter of 1998 from $464.0 million
in the third quarter of 1997.  The third quarter 1998 results of operations
include net revenues of K-C Aviation,  Inc.  from the date of  acquisition,
which were $35.2 million,  resulting  principally from the delivery of five
non-Gulfstream completions. Excluding the net revenues of K-C Aviation, the
Company's  net  revenues  were up $127.0  million,  or 27.4%.  The increase
resulted from several factors;  an increase in revenues from green aircraft
of $44.5 million as the Company delivered 16 aircraft,  seven Gulfstream Vs
and nine Gulfstream IV-SPs, as compared with 14 aircraft,  eight Gulfstream
Vs and six Gulfstream IV-SPs, in the third quarter of 1997; and an increase
in Gulfstream completion revenues of $30.7 million reflecting 11 Gulfstream
completions  delivered  during the third  quarter  compared  with only five
Gulfstream   completions  delivered  in  the  comparable  1997  period.  In
addition, revenues associated with the sale of pre-owned aircraft increased
$29.2  million to $45.0 million in the third quarter of 1998 as compared to
$15.8 million in the same period in 1997.

     During the nine months ended  September  30, 1998,  total net revenues
increased by $324.0 million (including the effects of the acquisition),  or
23.8%, to $1,686.6  million from $1,362.6 million for the nine months ended
September  30,  1997.  For  the  nine  months  ended  September  30,  1998,
Gulfstream  delivered 44 new  aircraft;  21 Gulfstream Vs and 23 Gulfstream
IV-SPs, up from 37 new aircraft;  21 Gulfstream Vs and 16 Gulfstream IV-SPs
in the same period of 1997.  Also  contributing to the increase in revenues
was an increase in completion revenues of $82.5 million,  resulting from 12
additional   Gulfstream   completion  deliveries  and  five  non-Gulfstream
completion deliveries in 1998.

     Cost of Sales.  Total cost of sales increased to $487.4 million in the
third quarter of 1998 from $373.0 million in the third quarter of 1997, and
increased  $197.7  million to $1,322.7  million  for the nine months  ended
September  30,  1998  from  $1,125.0  million  for the  nine  months  ended
September  30,  1997.  Cost of sales of the  acquired  business  includes a
non-cash  acquisition  related  charge of $3.9  million  for the fair value
step-up related to the sale of inventories.  Excluding  pre-owned aircraft,
which generally are sold at break-even  levels,  and the non-cash inventory
step-up of $3.9 million,  the gross profit percentage for the third quarter
of 1998 was 24.1%  compared to 19.3% for the third quarter of 1997, and for
the nine months ended  September 30, 1998, the gross profit  percentage was
23.5% compared to 19.1% for the comparable period in 1997. This increase in
gross  profit  percentages  is  primarily  attributable  to  reductions  in
Gulfstream V aircraft production costs.

     Selling and Administrative Expense. Selling and administrative expense
increased by $6.0 million,  or 25.1%, to $29.9 million in the third quarter
of  1998  from  $23.9  million  in the  third  quarter  of  1997,  but as a
percentage of net revenues,  decreased to 4.8% in the third quarter of 1998
from 5.2% in the third quarter of 1997. For the nine months ended September
30, 1998, selling and administrative  expense was $85.4 million as compared
to  $69.5  million  for the nine  months  ended  September  30,  1997.  The
principal drivers for the increase for both the quarter and the nine months
are additional sales and marketing  expenses  associated with the increased
sales activity,  the acquisition of K-C Aviation,  and the business systems
which are being  implemented  in 1998 and 1999 to  support  the  production
increases described elsewhere herein.

     Research and Development Expense. Research and development expense was
$2.7 million in the third  quarter of 1998,  as compared to $4.3 million in
the third  quarter of 1997.  For the nine month period ended  September 30,
1998,  research and development  expense was $7.0 million  compared to $8.1
million for the  corresponding  period in 1997.  Research  and  development
expense  for the nine  months  ended  September  30, 1997 is net of a $10.0
million   credit  for  launch   assistance   funds  received  from  vendors
participating  in  the  development  of  the  Gulfstream  V.  Research  and
development  expenditures in 1998 and the near-term  future are expected to
stem principally from product  improvements and  enhancements,  rather than
new aircraft  development.  

     Interest Income and Expense. Interest income decreased by $0.8 million
to $2.0 million in the third quarter of 1998 from $2.8 million in the third
quarter of 1997 as a result of lower  average cash balances the Company had
invested during 1998 compared to the same period of 1997.  Interest expense
decreased by $0.5 million to $7.0 million for the third quarter of 1998 and
by $2.9 million to $20.4  million for the nine months ended  September  30,
1998,  respectively,  over the comparable periods in 1997. This decrease is
attributable  to both a decrease in average  borrowings  and lower weighted
average interest rates.

     Income Taxes. In the quarter and nine month period ended September 30,
1998, the Company recorded income tax provisions of $34.0 million and $90.4
million,  respectively,  based on an estimated effective tax rate of 36.0%.
In the comparable  periods of 1997,  the Company  recorded no provision for
income taxes, other than alternative minimum taxes, principally as a result
of utilization of net operating loss carryforwards. As a result of numerous
factors, including, but not limited to the Company's recent earnings trends
and the size of its contractual  backlog,  the Company  determined that its
net deferred tax asset was more likely than not to be realized, and, in the
quarter  ending  September  30, 1997,  released its deferred tax  valuation
allowance, totaling $94.2 million. Of this amount, $29.4 million related to
the  exercise of stock  options  and was  credited  to  additional  paid-in
capital and $64.8 million was recorded as a one-time,  non-cash  income tax
benefit.  The Company's net operating loss carryforward for regular federal
income tax purposes was fully utilized during the second quarter 1998.

     Earnings Per Share. The Company reported diluted earnings per share of
$0.86 for the third  quarter 1998 as compared to the third  quarter of 1997
of $1.54 (or $0.70 per share,  excluding the one-time tax benefit discussed
above).  For the nine months ended  September 30, 1998,  earnings per share
was $2.13, compared to $2.54 (or $1.71 per share excluding the one-time tax
benefit  discussed  above) for the  corresponding  period in 1997. On a pro
forma  fully-taxed  basis,  and assuming an effective tax rate of 37.5% for
the 1997  periods,  comparable  diluted  earnings per share would have been
$.45 for the third quarter and $1.10 for the nine month period.

LIQUIDITY AND CAPITAL RESOURCES

     The Company's  liquidity needs arise  principally from working capital
requirements,  capital expenditures, and principal and interest payments on
long-term debt (including the revolving credit facility).  During 1998, the
Company  also  implemented  a share  repurchase  program and  acquired  K-C
Aviation.  During the nine months ended  September  30,  1998,  the Company
relied on both cash  balances  and its  revolving  credit  facility to fund
these needs.

     The Company had cash and cash  equivalents  totaling  $10.6 million at
September  30, 1998 down from $306.5  million at December  31,  1997.  This
decrease is  primarily  attributable  to the  acquisition  of K-C  Aviation
during the third quarter 1998 and the Company's share repurchase program.

     On August 19,  1998,  the Company  acquired  K-C  Aviation,  Inc.  for
approximately $250 million,  including acquisition costs. K-C Aviation is a
leading provider of business aviation services and the largest  independent
completion  center for business  aircraft in North America.  In addition to
custom  aircraft  interiors,  K-C  Aviation  is the second  largest  engine
service center in the United States and also offers  maintenance  services,
spares,  auxiliary power unit service,  avionics retrofit,  non-destructive
testing  and  component  overhaul.  The  acquisition  allows the Company to
obtain a skilled workforce as well as the additional capacity to accelerate
the  completions  ramp-up,  while at the same  time grow  service  revenues
through three new strategic locations.

     In January 1998, the Company established a program to repurchase up to
$200 million of its common stock.  As of September 30, 1998,  approximately
5.5  million  shares,  at an average  price of $35.81  per share,  had been
repurchased under this plan for an aggregate amount of approximately $198.5
million.

     During the nine months ended  September 30, 1998, net cash provided by
operating activities was $147.6 million compared with the nine months ended
September  30, 1997 when the Company  generated  $33.6 million in cash from
operations.  This  increase  is  primarily  attributable  to an increase in
pre-tax earnings.

     During  the third  quarter of 1998,  the  Company  together  with GATX
Capital  Corporation,   a  diversified   international  financial  services
company,  formed  Gulfstream  GATX Leasing  Company to provide an operating
lease program to customers in the large cabin, long range business aircraft
market.  Gulfstream  GATX Leasing  Company is owned 85% by GATX Capital and
15% by Gulfstream.

     During the nine months ended September 30, 1998, additions to property
and equipment amounted to $16.1 million. At September 30, 1998, the Company
was not committed to the purchase of any significant amount of property and
equipment.  As a result of the Company's  strategic  initiative to increase
its annual  production  rate to  approximately  65  aircraft  by 1999,  the
Company's planned capital  expenditures  increased $15 million in 1997, and
in 1998,  are  expected to increase  by  approximately  another $20 million
above previously  planned annual levels of approximately  $15 million.  The
Company  continually  monitors its capital  spending in relation to current
and anticipated  business needs. As circumstances  dictate,  facilities are
added, consolidated or modernized.

     In May 1998, certain shareholders of the Company completed the sale of
18,000,000 shares of common stock in a secondary offering (the "Offering").
The Company did not receive any of the proceeds  from the sale of shares in
the Offering.  In connection with the Offering,  certain current and former
directors and employees  of, and advisors to, the Company  exercised  stock
options to purchase, in the aggregate,  approximately 2.9 million shares of
common  stock  from  the  Company  for  an  aggregate   exercise  price  of
approximately  $27.1 million,  after deducting  issuance costs. The Company
used the proceeds from these exercises for working capital purposes.

     At September 30, 1998, borrowings under the Company's revolving credit
facilities were $50 million,  with available  borrowings of $134.7 million.
Scheduled repayments remaining under the term facility are $18.8 million in
1998 and $75.0  million in each of the years 1999 through  2001,  and $80.0
million in 2002. The Credit Agreement  contains  customary  affirmative and
negative covenants including restrictions on the ability of the Company and
its  subsidiaries  to pay cash  dividends,  as well as financial  covenants
under which the Company must operate. As of September 30, 1998, the Company
was in compliance with the covenants of its credit agreement.

     The Company's  principal  source of liquidity both on a short-term and
long-term  basis is cash flow provided by  operations,  including  customer
progress  payments  and  deposits  on new  aircraft  orders.  Occasionally,
however,  the Company may borrow against the credit agreement to supplement
cash flow  from  operations.  The  Company  believes  that  based  upon its
analysis of its consolidated  financial position,  its cash flow during the
past 12 months  and the  expected  results  of  operations  in the  future,
operating cash flow and available borrowings under the credit agreement and
other  available  financing  sources  will be adequate to fund  operations,
capital expenditures, and debt service for at least the next 12 months. The
Company  intends to repay its remaining  indebtedness  primarily  with cash
flow from  operations.  There can be no  assurance,  however,  that  future
industry  specific   developments  or  general  economic  trends  will  not
adversely  affect the Company's  operations or its ability to meet its cash
requirements.

     As of September 30, 1998, in connection  with orders for 21 Gulfstream
V aircraft in the  backlog,  the Company  has  offered  customers  trade-in
options (which may or may not be exercised by the customer) under which the
Company will accept trade-in aircraft (primarily Gulfstream IVs and IV-SPs)
at a guaranteed  minimum trade-in price.  Additionally,  in connection with
recorded sales of new aircraft,  the Company has agreed to accept pre-owned
aircraft with trade-in  values  totaling $281.9 million as of September 30,
1998.  Of this  amount,  $8.6  million  is under  contract  for  resale  to
pre-owned  aircraft  customers.  Management  believes  that the fair market
value of all such aircraft exceeds the specified trade-in value.

     On December 24, 1997, the Company  executed  final  documents with the
Pension Benefit Guaranty Corporation (the "PBGC") concerning funding of the
Company's  defined  benefit pension plans.  The terms were  essentially the
same as those set out in the  agreement  in principle  reached  between the
PBGC and the Company during October 1996.  Pursuant to this agreement,  the
Company  contributed  $18.8 million for the nine months ended September 30,
1998, and has agreed to contribute a total of $25.0 million annually (to be
paid quarterly in equal installments) from 1999 through 2000 to its pension
plans  which  payments  are  expected  to result in such plans  being fully
funded.  The payments to be made under this  agreement were already part of
the Company's overall financial planning,  and therefore,  are not expected
to have a material  adverse effect on the Company's  financial  statements.
The funding  required  under this agreement will not result in any increase
in the Company's annual pension expense.

CONTRACTUAL BACKLOG

     At  September  30, 1998,  Gulfstream  had a firm  contract  backlog of
approximately  $2.9  billion  of  revenues,  representing  a  total  of  91
aircraft.  The Company includes an order in backlog only if the Company has
entered into a purchase contract (with no contingencies)  with the customer
and has received a significant (generally  non-refundable) deposit from the
customer.

     During the third  quarter of 1998,  Gulfstream  GATX  Leasing  Company
executed  agreements  to purchase  five  Gulfstream  Vs and one  Gulfstream
IV-SP,  valued at  approximately  $210 million,  with  deliveries from 1999
through 2001. It also executed  options to purchase three Gulfstream Vs and
three  Gulfstream  IV-SPs,  valued  at  approximately  $200  million,  with
potential deliveries from 2001 through 2004.

     During the quarter  ended March 31,  1998,  the Company  signed a $335
million contract for 12 Gulfstream  IV-SPs to expand its highly  successful
Gulfstream Shares  fractional  ownership program to the Middle East region.
The first  green  aircraft  delivery  for the Middle  East  Shares  Program
occurred  during the third quarter of 1998.  The  remaining 11  undelivered
aircraft are not included in the Company's  backlog.  In 1993,  the Company
established very stringent deposit requirements for recording aircraft into
its backlog.  The contract  for the Middle East Shares  expansion  includes
modestly different deposit  requirements early in the program.  The Company
has  decided for the initial  phase of the program to record  these  orders
when the aircraft are delivered.  Including the 11 undelivered  aircraft in
the Middle East contract,  the Company had a total of 102 aircraft,  valued
at approximately $3.2 billion of potential future revenues,  under contract
at September 30, 1998.

     As part of the Company's ongoing Gulfstream Shares program, on October
16, 1998,  the Company  signed  agreements in principle  with Executive Jet
International (EJI) which significantly expands the successful relationship
between the two companies.  The agreements include plans for a Gulfstream V
Shares fractional  ownership program,  with the purchase of 10 Gulfstream V
aircraft  and options  for an  additional  12  Gulfstream  V aircraft,  the
purchase  of  14  Gulfstream  IV-SP  aircraft  to  supplement  the  current
Gulfstream  Shares  program  and  a  long-term  maintenance  agreement  for
Executive  Jet's fleet of Falcons and Hawkers in addition to the Gulfstream
jets.  The value of the purchase and service  agreements is estimated to be
nearly $1.3 billion and is excluded from the  Company's  September 30, 1998
contractual backlog.

     The Company  continually  monitors  the  condition  of its backlog and
believes,  based  on  the  nature  of  its  customers  and  its  historical
experience,  that there will not be a significant  number of cancellations.
However,  to the extent  that there is a lengthy  period of time  between a
customer's  aircraft  order and its delivery  date,  there may be increased
uncertainty  as to changes in business  and economic  conditions  which may
affect customer cancellations.

OUTLOOK

     The Company plans to deliver approximately 60 green aircraft in fiscal
1998 and 65 in fiscal 1999, and  completions  are expected to nearly double
in 1998  compared to 1997.  The gross  margins are expected to improve from
20% in 1997 to the  mid-20s  by the end of 1998.  Based on  projections  of
increasing  aircraft  production and improving margins,  Gulfstream expects
diluted  earnings  per  share of  approximately  $2.95 in 1998 and $3.75 in
1999. The Company is also targeting  diluted  earnings per share in 2000 to
increase 15% over 1999.

YEAR 2000 READINESS

     As part of the  Company's  initiatives,  begun  in 1996,  to  increase
production  rates and co-produce the Gulfstream IV-SP and Gulfstream V, the
Company has, and continues  to,  upgrade and replace  business  systems and
facility  infrastructure.  These  initiatives  help to reduce the potential
impact of the Year 2000 issue on the Company's operations.

     In addition,  the Company has  implemented a Year 2000 Compliance Plan
designed to ensure that all other hardware, software, systems, and products
with  microprocessors  relevant to the Company's business are not adversely
affected by the Year 2000  issue.  The  Company  has  established  a formal
program office under the leadership of a senior level executive,  to manage
the assessment and  implementation  of the Plan objectives.  The program is
reviewed regularly with executive management.

     Gulfstream has reviewed all current production  components and systems
installed in the  Gulfstream  IV-SP and Gulfstream V aircraft and has found
no issues. Older aircraft which are no longer under warranty have also been
reviewed  and  some  required  minor  component   modifications  have  been
identified and communicated to the relevant  customers.  Gulfstream intends
to substantially  complete Year 2000 compliance  remediation and testing by
the  first  quarter  1999,  with some  activities  continuing  through  the
remainder of 1999. Confirmations of Year 2000 plans for all high and medium
risk  suppliers  has  also  been  completed  and  low  risk  suppliers  are
approximately 90% complete.  Supplier Year 2000 compliance  monitoring will
continue through year-end 1999 and into the Year 2000.

     The  Company  currently  estimates  the total  costs of these  efforts
incurred  during  the years  1997  through  1999 to be  approximately  $3.5
million. In addition,  some non-compliant systems will be eliminated as the
Company  installs  Year 2000  compliant  software  in  connection  with its
ongoing integrated  resource planning project.  The cost of this effort has
been included in the Company's  capital  projections  discussed above under
the caption "Liquidity and Capital Resources".

     The Company does not believe that the implementation of this Year 2000
Compliance  Plan will have a  material  effect  on the  Company's  business
operations, financial condition, liquidity or capital resources. Management
of the Company believes it has an effective program in place to address the
Year  2000  issue in a  timely  manner.  As a  component  of the Year  2000
Compliance  Plan, the Company is developing  contingency  plans to mitigate
the effects of potential  problems  experienced by it or its key vendors or
suppliers in the timely  implementation  of its Year 2000 Compliance  Plan.
Nevertheless,  since it is not possible to anticipate all future  outcomes,
especially when third parties are involved, there could be circumstances in
which the Company's operations would be adversely affected.

     The  statements  in this  section  constitute  a "Year 2000  Readiness
Disclosure" under the Year 2000 Information and Readiness Disclosure Act to
the extent provided therein.

          NOW THEREFORE, for and in consideration of the premises herein
set forth and the terms and conditions hereinafter stated, the Authority
and Sublessee agree to and hereby do amend said Sublease Agreement dated
June 1, 1992, as amended, as follows, to-wit:

          1. Delete paragraph 3 in its entirety and insert the following in
             lieu thereof:

          Paragraph 3. Option to Renew. Sublessee shall have the option to
renew this Sublease for five (5) renewal terms of one (1) year and zero (0)
months beginning the 1st day of June 1998, unless this Sublease is
terminated as a result of Sublessee's default and breach.

          Sublessee shall not exercise any option to renew for more than
one renewal term at a time during either the base term or any renewal term
of this Sublease. Sublessee shall deliver to Sublessor written notice of

          Except for the amount of the rental rate, unless otherwise
provided for within Paragraph 4 all agreements and conditions in this
Sublease shall have the same force and effect for each renewal term as for
the base term unless the parties otherwise agree in writing.

          At the end of the last of the five renewal terms, the Sublessee
may request new negotiations for the leasehold and improvements. This
request shall be submitted in writing at least ninety (90) days prior to
the termination of the last option period. The Sublessor agrees to enter
into good faith negotiations prior to negotiations with any other
prospective Sublessee.

                                   -----


WHEREAS, OUTAGAMIE COUNTY, a Wisconsin Municipal corporation and
KIMBERLY-CLARK CORPORATION, a Delaware corporation, have heretofore entered
into a "Lease With Option To Renew" dated January 25, 1968, together with
certain subsequent additions, which instrument is hereby assigned (to which
assignment Outagamie County hereby consents) by Kimberly-Clark Corporation
to its wholly-owned subsidiary, K-C AVIATION INC., a Delaware corporation;
and

WHEREAS, the said parties now desire to modify, amend and reconstruct the
said Lease with such amendments and modifications that it becomes desirable
to enter into a totally new agreement;

NOW, THEREFORE, it is agreed by and between the parties hereto as follows:

1.   PARTIES. Outagamie County shall be hereafter referred to as LESSOR and
     K-C Aviation Inc. will be hereafter referred to as LESSEE.

2.   PREMISES. The LESSOR does hereby and by these presents does lease, let
     and demise unto the LESSEE and the LESSEE does hereby take and rent
     from the LESSOR the land situated in the State of Wisconsin, County of
     Outagamie, Town of Greenville, described on Exhibit "A", which is
     attached to and made a part of this Lease.

     [Illegible] being a part of the Outagamie County Airport, and
     hereafter referred to as the "Premises", upon the terms and conditions
     hereinafter set forth. LESSEE shall have the exclusive use of and the
     right at any time to enclose by fencing, the apron and supporting
     facilities, a "fuel farm" consisting of buried or surface tanks for
     not less than 20,000 gallons of aviation fuels, 50 gallons of oil and
     lubricants, and 10,000 gallons of heating fuels together with power
     lines, pumping, venting and other necessary or desirable facilities as
     LESSEE may reasonably require, and access roads for heavy transport
     between the LESSEE Improvements (as hereinafter defined) and fuel farm
     areas and public access roads.

3.   TERM. The initial term of this Lease shall commence upon the
     cancellation of the heretofore referred to "Lease With Option To
     Renew" dated January 25, 1968, which said cancellation shall occur at
     such time as the completion of transfer of ownership of the present
     improvements on the Premises from the LESSOR to the LESSEE. This
     initial term shall end on the 31st day of March, 1984. LESSEE is
     granted an option to renew this Lease for nine (9) additional
     consecutive five (5) year terms upon written notice to LESSOR sent at
     least thirty (30) days prior to the expiration of the initial Lease
     term or any renewal term, on the same terms and conditions as herein
     stated, except as to the amount of rent.

4.   Rents. LESSEE shall pay as rent under this Lease, for the initial
     term, in equal monthly installments due and payable on the first
     business day of each and every month, annual rental of $.05 per square
     foot for the total Premises heretofore described, being 254,720 square
     feet. If LESSEE shall exercise its option to renew this Lease for the
     first renewal period commencing April 1, 1984 and ending March 31,
     1989, the annual rent to be paid by LESSEE, upon the same terms and
     conditions, shall be the sum of $.08 per square foot. The annual
     rental, per square foot, of subsequent renewal periods shall be
     determined at the commencement of each five year renewal period based
     on the amount of the rent for the preceding term, adjusted at the rate
     of one quarter (1/4) of the increase or decrease of the average of the
     consumer price index (hereafter referred to as "CPI") as published by
     the United States Department of Labor, Bureau of Labor Statistics for
     the calendar year preceding the date of renewal as compared to the
     index used for the calculation of any rent adjustment for the prior
     renewal term. As example and explanation, the rent for the second
     renewal term (that commencing April 1, 1989) would be computed by
     using the average CPI for calendar year 1983 as the base index
     compared with the average CPI for calendar year 1988, with one quarter
     (1/4) of the difference of the two average CPIs being used as the
     percentage to adjust the preceding annual rental amount ($.08 per
     square foot). The third renewal term shall use the average CPI for
     calendar year 1988 as the base index to be compared with the average
     CPI for calendar year 1993; the rent for the fourth and succeeding
     renewal terms calculated in the same fashion.

5.   LESSOR'S CONSTRUCTION OBLIGATION AND LESSEE'S IMPROVEMENTS. In
     entering into this new Lease, it is the understanding of the parties
     hereto that the LESSEE will construct an addition (the plans for which
     have been reviewed and approved by LESSOR) to the presently existing

     addition shall be referred to herein as the "Lessee Improvements"),
     the said present existing improvements to be purchased by the LESSEE
     from the LESSOR for the sum of $300,000. The purchase of the existing
     Building improvements by LESSEE from LESSOR shall be closed within
     thirty (30) days of the date of this Lease and shall take place at the
     site specified by LESSOR in Outagamie County, Wisconsin, unless the
     parties agree otherwise. LESSOR, at such closing after receipt of
     payment from LESSEE, shall deliver a Bill of Sale or other similar
     documents satisfactory in form to LESSEE'S counsel, transferring the
     present Building improvements to LESSEE free and clear of all liens
     and encumbrances, except those created by LESSEE. Upon transfer of the
     present Building improvements and after construction of the addition
     contemplated by LESSEE, title to these LESSEE Improvements shall be in
     LESSEE until the expiration or termination of this Lease after which
     title shall be transferred to LESSOR pursuant to the Purchase
     Obligation provided for in paragraph 18 hereof. LESSOR agrees that it
     will promptly construct, at its expense, necessary ramp facilities, as
     an addition to the presently existing ramp, so as to give access to,
     and to make usable and serviceable, the addition to the present
     Building improvements, which said addition is to be constructed by the
     LESSEE.

     property damage, and single limit of at least $20,000,000 for
     liability arising out of repair and servicing of aircraft, insuring
     LESSOR as well as LESSEE against claims or liability for damages on
     account of the deficiency or claimed deficiency of any of the LESSEE
     Improvements on the Premises during the terms hereof.

8.   REPAIRS, MAINTENANCE, COMPLIANCE WITH SAFETY RULES, ETC. LESSEE agrees
     to be responsible for all repairs, maintenance, replacements and
     general upkeep, whether structural or non-structural and whether of
     exterior or interior portions, to the LESSEE Improvements, and whether
     or not the same are required for underground utilities and
     installations except that at the time of closing of the transfer of
     ownership of the present Building on the Premises from the LESSOR to
     the LESSEE, items of repair and maintenance which are the
     responsibility of the LESSOR under the original "Lease With Option To
     Renew" shall be completed at the expense of the LESSOR. Lessor will at
     all times keep all sidewalks, steps and exits (except those within the
     immediate vicinity of the LESSEE Improvements), aprons, taxiways,
     access roads and all other Outagamie Airport facilities in good,
     clean, safe, secure, sanitary condition and repair and will conform to
     all ordinances, laws, rules and regulations of any public agency
     having dominion or jurisdiction thereof respecting all matters
     including safety and sanitation, snow removal and street oiling
     (including but not limited to Federal Aviation Administration
     requirements), and will save the LESSEE free and harmless from any
     personal or other liability whether or not occasioned by the
     negligence of the LESSOR or any agent or any person contracting with
     said LESSOR for the maintenance and care of such areas, or out of any
     accident or occurrence causing injury or claimed injury of any person
     whomsoever or property whatsoever due directly or indirectly to the
     maintenance and repair of such areas, including the cost of defending
     such claim. Snow removal shall be accomplished so as to comply with or
     exceed air carrier requirements for aircraft departures and arrivals
     as the same may be in force from time to time. LESSOR shall also be
     responsible for, throughout the term of this Lease and any renewals
     thereof, lawn maintenance and similar items which are not connected
     with the maintenance of the LESSEE Improvements upon the Premises.

9.   HEAT, LIGHTS AND WATER. LESSEE shall furnish and pay for all utilities
     including heat, lights, water and gas required or used by it upon said
     Premises.

10.  USE OF PREMISES. LESSEE covenants and agrees that it will not use the
     Premises or the LESSEE Improvements thereon, during the term of this
     Lease for any purpose other than for aviation purposes or for any
     purpose which is lawful under the laws of the United States, the State
     of Wisconsin or the ordinances of Outagamie County or any laws, rules
     or regulations of any proper agency of any government having dominion
     thereover; otherwise, there shall be no limitation whatsoever on
     LESSEE'S use of the Premises or the LESSEE Improvements. In the event
     LESSEE shall, pursuant to 14 CFR 121.1 (a)(1), (2), and (3), commence
     any commercial aeronautical operations carrying passengers with
     established schedules on the Premises, LESSEE shall then pay all
     landing or user fees required of and collected from other such
     commercial operators and abide by all rules and regulations pertaining
     to commercial operators on the airport. LESSEE, its agents and
     employees will not discriminate against any person or class of persons
     by reason of race, color, creed, sex or national origin in providing
     any services or in the use of any of its facilities provided for the
     public in any manner prohibited by 49 CFR Parts 21 and 23 of the
     Federal Aviation Regulations.

11.  ASSIGNMENT. LESSEE may assign or sublet this Lease to its parent
     corporation, Kimberly-Clark Corporation, or any of the subsidiaries of
     Kimberly-Clark Corporation now existing or hereafter incorporated, but
     otherwise shall not assign this Lease or any part thereof without
     prior written consent of the LESSOR, except to another person, form or
     corporation acquiring all or a substantial part of LESSEE'S assets
     used for aviation purposes. LESSOR shall not unreasonably withhold its
     consent.

12.  FORFEITURE ON DEFAULT. If any default shall be made by the LESSEE in
     any payment of rent, or if LESSEE shall fail to keep and perform any
     other covenant, condition or agreement herein provided on the part of
     the said LESSEE to be performed and such default shall exist without
     being fully remedied for a period of 30 days after LESSOR has given
     LESSEE written notice thereof, then it shall be lawful without further
     notice, to declare the term of this Lease ended and LESSOR shall have
     the right to re-enter and reposess the Premises, either with or
     without process of law, and LESSEE does hereby waive, in such event,
     any demand for possession of the demised Premises, and LESSEE
     covenants and agrees to surrender the Premises to LESSOR or the agents
     or attorneys of LESSOR, immediately upon the termination of this
     Lease, at the election of LESSOR.

13.  FORFEITURE ON INSOLVENCY. Should LESSEE become bankrupt or make an
     assignment for the benefit of creditors either voluntary or
     involuntary, or be placed in receivership either voluntary or
     involuntary, the term of this Lease, and all the provisions hereof
     shall terminate forthwith upon such event occurring, without notice.

14.  QUIET ENJOYMENT. LESSOR covenants that LESSEE, its successors and
     assigns, on paying the rent in accordance with this Lease and
     performing the other covenants of this Lease to be performed by
     LESSEE, shall and may have, hold, occupy and enjoy peacefully and
     quietly the Premises for the term of this Lease and any renewal term
     without hindrance or molestation by anyone whomsoever. If LESSOR'S
     title shall prove to be defective in any respect, LESSEE may either
     cure the defect at LESSOR'S expense or forthwith cancel this Lease
     without liability, at its option.

15.  SECURITY, SAFETY AND FACILITIES. It is the intention of both LESSOR
     and LESSEE that the Premises may be freely, effectively and safely
     used by LESSEE for its aircraft operations; to that end, LESSOR shall
     provide or cause to be provided adequate facilities therefor,
     including but not limited to the following:

     a.   Adequate police and security protection at least equal to
          generally prevailing standards;

     b.   Adequate fire protection with full water pressure for the present
          paint and lubrication rooms in the existing Building Improvements
          sufficient to obtain the lowest fire insurance rates available
          for such facilities, and a crash [Illegible]

     c.   Complete air navigation and control radio facilities.

16.  REMEDIES AND RIGHTS CUMULATIVE. The specific rights and remedies of
     the parties under this Lease are cumulative, and not intended to be
     exclusive of or in derogation of any other rights or remedies
     available in the event of breach or threatened breach, all of which
     are hereby specifically preserved. The failure to require the strict
     performance of any covenant of this Lease or to exercise any option
     under this Lease, in any one or more instance, shall not be construed
     as a waiver or relinquishment for the future of the same or any other
     covenant or option.

17.  CAPTIONS. The captions in this Lease are for the purposes of
     convenience and reference only and are not to be deemed or construed
     as a part of this Lease nor supplemental or amendatory hereto.

18.  PURCHASE OBLIGATION. Commencing with the first renewal period of this
     Lease on April 1, 1984, if such renewal option shall have been
     exercised by the LESSEE, LESSOR shall purchase any and all LESSEE
     Improvements on the Premises at any time after the end of the initial
     term, including those present improvements whose ownership is being
     transferred from the LESSOR to the LESSEE pursuant to paragraph 5
     hereof, upon the occurrence of any one or more of the following
     conditions: 

     a.   Upon either the unremedied default by LESSEE of any provision of
          this agreement and the retaking of the Premises by LESSOR, in the
          event LESSEE fails to renew this Lease for the second or
          subsequent renewal terms pursuant to LESSEE'S renewal rights
          contained in paragraph 3 of this agreement or at the expiration
          of this Lease at the end [Illegible] Upon any of these
          occurrences, the purchase price for the LESSEE Improvements shall
          be seventy-five percent (75%) of the market value thereof as
          determined by the appraisal procedure set forth hereafter.

     b.   Upon termination of this Lease by LESSEE pursuant to paragraph 19
          hereof, provided LESSEE is not in default of any material
          provision hereunder, if any one or more of the following events
          exists:

          1.   The discontinuance by Outagamie County of the operation
               known as the Outagamie County Airport in such fashion that
               the LESSEE will be unable to continue its use of the
               Premises for the intended purpose;

          2.   The assumption by the United States Government or any other
               governmental agency or instrumentality of the operation,
               control, or use of Outagamie Airport in such a manner as to
               preclude LESSEE from using such Airport in the conduct of
               its business;

          3.   A default by LESSOR to meet and observe any of the material
               covenants herein contained if such default continues for a
               period of thirty (30) consecutive days or more after written
               notice to LESSOR by LESSEE, unless LESSOR has begun, and is
               continuing, in good faith to remedy in such interval and if
               such default precludes LESSEE from using such Airport in the
               conduct of its business. The purchase price for the LESSEE
               Improvements upon any one of these occurrences shall be the
               full market value thereof as determined by the appraisal
               procedures set forth hereafter.

In the event that the Purchase Obligation heretofore described shall be
activated, the market value of LESSEE'S Improvements shall be established
within thirty (30) days after the date requiring LESSEE to so purchase.
Closing of the purchase shall occur within thirty (30) days of the
establishment of the market value and shall take place at the site
specified by LESSOR in Outagamie County, Wisconsin, unless the parties
agree otherwise. LESSEE, at such closing after receipt of payment from
LESSOR, shall deliver a Bill of Sale or other similar document satisfactory
in form to LESSOR'S counsel, transferring the LESSEE Improvements to LESSOR
free and clear of all liens and encumbrances arising out of LESSEE'S acts
or omissions. The market value of the LESSEE Improvements shall be
determined by an appraiser mutually agreed upon by the parties. If the
parties cannot agree on a sole appraiser, each of the parties shall name
one appraiser, such appraisers shall in turn select a third, and the
selected appraisers shall act promptly to determine the market value. The
decision, and agreement, of any two of the appraisers as to the market
value shall be binding on the parties. Cost of the appraisal shall be
shared equally by the parties.

19.  LESSEE'S TERMINATION RIGHTS. Upon the occurrence of any of the
     following events, LESSEE may terminate this Lease in accordance with
     the following terms and conditions upon sixty (60) days prior written
     notice to LESSOR:

     a.   The issuance by any court of competent jurisdiction of any order
          preventing or restricting the use of the Outagamie County Airport
          for the purposes intended by this Lease, if the same shall
          apparently be likely to remain in force and effect for a period
          of sixty (60) consecutive days or more; the rental required of
          LESSEE shall be abated for that period of time that such order is
          in effect preventing or restricting the use of Outagamie County
          Airport prior to LESSEE'S termination of the Lease;

     b.   The assumption by the United States Government of any other
          governmental agency or instrumentality of the operation, control
          or use of Outagamie County Airport for national defense in such a
          manner as to preclude LESSEE from using such Airport in the
          conduct of its business for a period of ninety (90) consecutive
          days or more; the rental required of LESSEE shall be abated for
          that period commencing with the said assumption and prior to the
          effective date of LESSEE'S termination of the Lease;

     c.   A default by LESSOR to meet and observe any of the material
          covenants herein contained, if such default continues for a
          period of thirty (30) consecutive days or more after written
          notice to LESSOR by LESSEE, unless LESSOR has begun, and is
          continuing, in good faith to remedy the default in such
          intervals; the rental required of LESSEE shall be abated during
          the entire period of such default; or

     d.   In the event a substantial part of the LESSEE Improvements are
          destroyed by fire, rain, wind, or other cause beyond the control
          of LESSEE; the rent shall abate as of the date of such
          destruction.

20.  FIXTURES. LESSEE shall have the right to remove from the Premises upon
     the termination of this Lease all machinery, equipment and fixtures
     including but not limited to shelving, counters, bins, and storage
     tanks (whether or not buried), whether or not attached to the LESSEE
     Improvements or the Premises, but LESSEE shall, following such
     removal, restore the Premises to their former condition, ordinary wear
     and tear and damage from fire or other casualty excepted.

21.  RIGHT OF FIRST REFUSAL. If LESSOR receives a bona fide offer for the
     purchase of the Premises or any part thereof or a bona fide offer for
     the purchase of any tract of which the Premises are a part which
     LESSOR intends to accept, it will first give LESSEE a right of first
     refusal; that is, it will give LESSEE written notice of the terms of
     the offer and LESSEE will then have thirty days in which to notify
     LESSOR whether it elects to purchase on the same terms and conditions
     including price as set forth in the offer; if LESSEE notifies LESSOR
     within such 30 day period that it elects to purchase, the transaction
     will be closed as soon as feasible; if LESSEE has not notified LESSOR
     in writing that it elects to purchase within 30 days after having
     received notice from LESSOR, then LESSEE shall be deemed to have
     waived its right to purchase and LESSOR shall be free to sell the
     Premises or the part thereof or the tract of which the Premises are a
     part, as specified in the notice upon terms and conditions not more
     favorable to the purchaser than those set forth in the notice,
     provided the transaction is closed within 6 months after the notice
     was given; if sale to the proposed purchaser has not been completed
     within such 6 month period, then LESSOR, before selling to that
     proposed purchaser or another party, must again give LESSEE notice and
     a right of first refusal as if the first notice had not been given.

22.  ADDITIONS, REMOVALS AND ALTERATIONS BY LESSEE. LESSEE shall have the
     right, while not in default under this Lease, from time to time, in
     such manner and to such extent as LESSEE may deem desirable, to
     construct further improvements on the Premises, subject to the
     approval by LESSOR of the plans for construction, which approval shall
     not be unreasonably withheld. All additions to the Premises shall
     belong to LESSEE and shall be considered an addition to and a part of
     the LESSEE Improvements after construction.

23.  EXPANSION AREA. The area within 200 feet to the west (except that area
     currently in the roadway right-of-way approximately 175 feet from the
     west boundary line) and 400 feet to the east of the western and
     eastern boundaries, respectively, of the Premises and having the same
     north-south depth as the said western and eastern boundaries
     (hereinafter called the "expansion area") shall be reserved for
     expansion of LESSEE'S operations; LESSOR hereby grants to LESSEE an
     option, to be exercised at any time while any part of the expansion
     area remains unimproved by LESSOR, by giving 30 days' written notice
     to LESSOR, to add to the area included within this Lease any or all of
     such unimproved expansion area at the same rental as is then being
     paid for the Premises for a term which shall be the same as the
     unexpired term of this Lease with the same renewal option provisions
     and subject to the same rental adjustments. LESSOR will not construct
     any building or otherwise improve the expansion area without LESSEE'S
     prior written consent. If LESSOR shall request such consent and LESSEE
     shall deny the same, without itself exercising the aforesaid option to
     expand, then, in that event, LESSEE shall pay to LESSOR one quarter
     (1/4) of the then applicable rental per square foot for the Premises
     for the duration of the Lease and its renewal periods or until the
     LESSEE shall either exercise its option to utilize the said expansion
     area or consent to LESSOR'S proposed use of the expansion area.

24.  FUEL FLOWAGE CHARGES. LESSEE shall pay to LESSOR a use charge of three
     cents ($.03) a gallon for all types of aviation fuel, aviation
     gasoline, jet fuel, now used or which may be used in the future, sold
     by LESSEE at said airport to purchasers other than to either
     commercial airlines for the operation of regularly scheduled flights
     to and from said airport, to any government for military aircraft or
     to LESSEE'S parent or affiliated corporations. It is expressly
     understood by and between the LESSOR and LESSEE that said gallonage
     charge shall be subject to reexamination and reasonable adjustment to
     a higher or to a lower figure at the end of the initial term and each
     five (5) year renewal period of this Lease, but no change shall be
     made without the mutual written consent of LESSOR and LESSEE. LESSOR
     shall have the right to audit such of LESSEE'S books as pertain to the
     sale of such fuels for the appropriate period, such audit to verify
     the accuracy of LESSEE'S payments and will be made by an auditor
     acceptable to both LESSOR and LESSEE, at a cost to be shared equally
     by LESSOR and LESSEE, with copies of the audit report to be furnished
     promptly to LESSOR and LESSEE upon completion. Audit of Fuel Flowage
     Charges shall be determined in accordance with the Minimum Standard as
     adopted by the Outagamie County Board of Supervisors.

25.  CONTINUITY. This Lease and the provisions hereof shall be binding upon
     and inure to the benefit of the successors and assigns of LESSOR and,
     where permitted in harmony with the provisions hereof, to the benefit
     of the assignees and subtenants of LESSEE.

26.  NOTICES. The mailing addresses for mailing of notices required under
     the terms of this Lease are as follows:

                              FOURTH ADDENDUM


          THIS FOURTH ADDENDUM is entered into this 22nd day of October,
1996, between OUTGAMIE COUNTY ("LESSOR") and K-C AVIATION INC. ("LESSEE").

                           W I T N E S S E T H :

          WHEREAS, the parties have entered into a Lease on October 9,
1980, (hereinafter the "Lease"), providing for the lease from LESSOR by
LESSEE of land situated in the State of Wisconsin, County of Outagamie,
Town of Greenville, located at the Outagamie County Airport; and
 
          WHEREAS, the parties have previously amended the Lease by a First
Addendum dated the 24th day of December, 1980, a Second Addendum dated the
25th day of March, 1988, and by a Third Addendum dated the 9th day of
October, 1990; and

          WHEREAS, the parties desire to amend the Agreement by this Fourth
Addendum; and

          NOW, THEREFORE, in consideration of the mutual benefits,
covenants and obligations of the parties contained in the Lease, in the
First, Second and Third Addendums, and in this Fourth Addendum, Lessor and
Lessee agree to amend the Lease as follows:

          1.   Paragraph 2, PREMISES, is amended by adding an additional
Exhibit to the Lease designated as Exhibit D which is attached hereto and
made a part hereof. Exhibit D describes and provides for additional land
leased by LESSEE from LESSOR hereunder and together with the other Exhibits
previously added in prior addendums, describe all of the land leased by
LESSEE from LESSOR pursuant to the Lease.

          2.   The rent for the additional land shall be calculated in
accordance with the pricing formula in Paragraph 4, RENTS, of the Lease.

          3.   The parties understand and agree that the purpose of amending
the Lease to provide for additional land is to enable LESSEE to construct
new facilities. The parties agree that such new facilities shall not be
included within the definition of Lessee Improvements in Paragraph 5,
LESSOR'S CONSTRUCTION OBLIGATION AND LESSEE'S IMPROVEMENTS, of the Lease.
Consequently, the parties agree that LESSOR shall have no obligation to
purchase new improvements made on the land leased pursuant to this Fourth
Addendum in accordance with Paragraph 18, PURCHASE OBLIGATION, but that
LESSOR retains the obligation under the Lease to purchase all improvements
in existence on the date of this Fourth Addendum. Further, the parties
agree that LESSOR shall not have to purchase any improvements constructed
after the date hereof on any part of the land described in and subsequently
leased by LESSEE from LESSOR pursuant to Paragraph 23, EXPANSION AREA, of
the Lease.

          4.   Paragraph 18, PURCHASE OBLIGATION, section a., shall be
amended by changing the percentage of the market value of Lessee
Improvements which shall constitute the purchase price, from seventy-five
percent (75%) to fifty percent (50%).

          5.   Only in the event where LESSEE shall not renew the Lease
pursuant to Paragraph 3, TERM, at the end of an extension term, LESSEE
shall have the right to continue the Lease in accordance with its
provisions for a period of up to two (2) years after the end of such
extension term in order to allow LESSEE an opportunity to sell all of the
LESSEE Improvements (both the improvements which LESSOR shall be required
to purchase and the improvements which are to be constructed hereafter
which LESSOR shall have no obligation to purchase). LESSOR'S prior written
consent shall be required before the sale of the improvements, which
consent shall not be unreasonably withheld. Any sale of the improvements
shall be subject to the continuance of the present use of the improvements
for aviation purposes and to the proof of the financial viability of the
purchasing entity. The rent to be paid during such period shall be reduced
to fifty percent (50%) of the rent then being paid by LESSEE to LESSOR at
the end of such extension term, but only if LESSEE shall not be conducting
aviation completion business on the Premises during such period. Should
LESSEE be unable to sell the improvements during the period, LESSOR shall
be required to purchase the LESSEE Improvements in existence on the date
hereof (but not the new improvements as provided for above in paragraph 3)
pursuant to paragraph 18, PURCHASE OBLIGATION, with the market value of the
improvements to be determined as of the date when LESSEE advises LESSOR
that no purchaser can be located and that the Lease shall be considered to
have ended. Further, where LESSEE shall be required to structure any sale
of the LESSEE Improvements as a part of an assignment or sublease of this
Lease, there shall be no change to LESSOR'S obligation to purchase the
applicable (as provided for above in paragraph 3) LESSEE Improvements and
LESSOR shall purchase such improvements at the end of the Lease from
LESSEE's assignee or sublessee. The parties agree that all of the
improvements on the land leased hereunder by LESSEE from LESSOR, shall be
conveyed and transferred to LESSOR by LESSEE or its assignee or sublessee
at the end of the Lease simultaneously with the closing on LESSOR'S
purchase of the applicable LESSEE Improvements.

          6.   In the first sentence, fourth line of the second paragraph on
page 12 of the Lease in Paragraph 18, PURCHASE OBLIGATION, the word
"LESSEE" between the words "requiring" and "to so purchase" shall be
deleted and the word "LESSOR" shall be inserted.

          7.   LESSOR shall continue snow removal on the existing parking
lots on the Premises, except, however, LESSEE shall be responsible for snow
removal on any areas within the leased area described in Exhibit D.

          8.   LESSOR shall move its fence to outside of the boundaries of
the leased area described in Exhibit D.

          9.   LESSOR shall reserve and make available fifty (50) parking
spaces for use of the construction personnel during the duration of the
construction of the new improvements on the leased area described in
Exhibit D. LESSEE shall pay for the parking permits for such spaces.

          10.  Except as previously amended, the Lease in all other respects
shall be unchanged.


          IN WITNESS WHEREOF, the parties have executed this Fourth
Amendment upon the date first above written.

and LESSEE agree to amend the Lease as follows:

          1.   Paragraph 2, PREMISES, is amended by adding an additional

          floor space, with paved ramp area adjoining (called "Hangar
          Building").

     (2)  A prefabricated steel building approximately 175 feet long and 60
          feet wide (called "Cargo Building"), containing approximately
          10,500 square feet of floor space, which the parties agree may be
          removed by Lessee at its cost and relocated at Dallas Love Field
          as directed by Lessor.

This parcel is more particularly described on EXHIBIT A which is attached
hereto and made a part hereof for all purposes.

The second parcel (called "Parcel B") is approximately 247,059.302 square
feet of land within the boundaries of Love Field in the City and County of
Dallas, State of Texas, which is more particularly described on EXHIBIT B
which is attached hereto and made a part hereof for all purposes.

                                    II.

Lessor and Lessee agree that the terms, conditions and covenants of this
Lease are as follows:


1.   PRIMARY TERM AND EXTENSION

     (a)  This Lease shall be for a primary term of ten (10) years
          beginning February 1, 1978, and running through January 31, 1988.

     (b)  Lessee shall have an option to extend this Lease for four(4)
          additional terms of five (5) years each, the first extension term
          beginning on February 1, 1988. Each of the options may be
          exercised by Lessee by giving Lessor's Director of Aviation
          written notice sixty (60) days prior to the end of the then
          current term and by negotiating a mutually acceptable rental rate
          during such sixty (60) day period for such five year extension.
          The new rental rate will be based on comparable rates then
          prevailing for similar ground and buildings at comparable
          airports located in the Southwestern United States (Texas,
          Oklahoma, New Mexico, Louisiana and Arkansas) without
          consideration of leasehold improvements added by Lessee. Should
          Lessee fail to exercise any of its options to extend this Lease,
          Lessee shall no longer have an option to extend this Lease for
          subsequent five (5) year terms and this Lease shall thereupon
          terminate, provided, however, that Lessee may extend this Lease
          on either Parcel A, Parcel B, or both and if this Lease is
          extended on one parcel only, Lessee's options to extend this
          Lease will be extinguished only upon the parcel upon which Lessee
          did not exercise its option to extend.

     (c)  The parties acknowledge that Parcel A is subject to a lease dated
          December 14, 1977 between Lessor and ONE AVIATION PLACE, INC., a
          Texas corporation, whose principal offices are located at 900
          Southland Center, Dallas, Texas 75201 (called "One Aviation"),
          which lease One Aviation has applied to the Lessor for
          modification to exclude such Parcel A. In consideration of the
          relinquishment of One Aviation's rights to Parcel A, Lessor
          agrees that in the event of the cancellation or termination of
          this Lease for reason of default by either party or in the event
          Lessee shall fail to exercise any extension option on either
          Parcel, One Aviation, or its successors or assigns, shall have
          the first right, but not the obligation, to cure any default of
          Lessee or exercise such extension upon Parcel A, Parcel B, or
          both thereby assuming the obligations of Lessee under this Lease.
          One Aviation will have fifteen (15) days after receipt of notice
          from Lessor in which to exercise this first right. If One
          Aviation succeeds to Lessee's interest, Lessee shall be fully
          released from further liability hereunder, notwithstanding
          provisions to the contrary herein.

2.   RENTAL

     (a)  Subject to reduction pursuant to 2(c) below, the rental for each
          full year of this Lease during the primary term shall be
          $79,900.68 (calculated pursuant to 2(b) below) payable in equal
          monthly installments of $6,658.39. However, no rental shall be
          due from Lessee for either Parcel A or B until Lessor's Director
          of Aviation has determined that Lessee is beneficially occupying
          such Parcel and Lessee is advised accordingly in writing.

          By the first day of each month, Lessor shall forward to Lessee a
          written invoice covering such monthly period, which invoice shall
          be due and payable within ten (10) days after receipt thereof.
          Payments of such rent shall be made to the City of Dallas,
          Department of Aviation, Love Field Terminal Building, Dallas,
          Texas 75235.

     (b)  The amount of rent, as set forth in (a) of this Section, is based
          on the following rates and computations:

Type of                                     Annual Charge       Total Per
 Space                      Square Feet     Per Square Foot        Year
- -------                     -----------     ---------------     ----------
Hangar Building              35,475              $1.00          $35,475.00
Cargo Bldg. Space            10,500              $0.90          $ 9,450.00
Unimproved Land
(aggregate of
Parcels A and B)            349,756.772          $0.10          $34,975.68
                                                                ----------

                                           TOTAL                $79,900.68

     (c)  Notwithstanding the foregoing, when the Cargo Building is removed
          by Lessee, the rental rate for the approximately 10,500 square
          feet of land occupied by the space of such building shall be
          reduced from $0.90 per square foot to $0.10 per square foot and
          the annual rental and monthly installments for the premises and
          the facilities shall be reduced accordingly beginning as of the
          first day of the month following removal of such building.

3.   USE OF PREMISES

     Lessee shall have the right to use the premises and facilities for
     fixed base operations, as follows:

     (a)  Maintenance and operation of a hangar, quarters, facilities and
          equipment required by Lessee in connection with the conduct of
          its general aviation business, including air cargo, air mail and
          air express, the receipt, distribution, manifesting, billing and
          storage of air cargo, air mail and air express and activities
          necessary or convenient in connection with the handling thereof,
          and operations, administrative and other offices. If Lessee
          commences the sale of aviation fuel at retail at Dallas Love
          Field, it shall prepare and submit reports indicating fuel flow
          fees and amounts for landing fees, on such forms and at such
          reasonable intervals as directed by Lessor's Director of
          Aviation.

     (b)  Parking, storage, loading, unloading and routine repairing,
          conditioning, sale and maintenance of aircraft and other
          equipment used in the operation of private, executive, charter or
          any other type of flight, the servicing of aircraft and other
          equipment, by truck or otherwise, with any fuel, or propellant,
          oil, greases, lubricants, or other supplies, and operation of a
          flight school.

     (c)  Storage, maintenance and servicing of ramp equipment and any
          other equipment, materials and supplies.

     (d)  Operation of employee facilities, including parking for
          automobiles and equipment and the operation of facilities to
          provide meals for its employees and guests.

     (e)  Constructing, erecting or otherwise obtaining additional
          buildings and facilities on the premises, at Lessee's sole cost
          and expense, subject to the prior written approval of Lessor's
          Director of Aviation, and upon such terms and conditions as may
          be set out in such approval. Such additional improvements shall
          become the property of Lessor when placed on the premises, unless
          either the Lessor grants to Lessee the right of removal in
          conjunction with its approval of plans for the same or Lessee
          terminates this Lease pursuant to Section II.13. Lessor agrees
          that no other rental for the premises and facilities, as
          hereinbefore set forth, will be charged Lessee in respect to its
          providing such other services and facilities for itself.

     (f)  Carrying on of any and all other operations and activities
          reasonably necessary or convenient to the conduct by Lessee of
          fixed base operations for general aviation purposes.

4.   MAINTENANCE AND REPAIR OF PREMISES

     While this Lease is in effect, the respective obligations of the
     parties for maintaining and repairing the premises shall be as
     follows:

     (a)  Lessee shall keep the premises and facilities in a clean and
          orderly condition. When Lessor calls Lessee's attention to
          deficiencies in this regard, Lessee shall promptly undertake
          corrective action.

     (b)  Lessee shall be responsible for maintenance and repair of the
          existing facilities and any additional ones constructed or
          installed by Lessee, including interior and exterior of buildings
          and the heating and air-conditioning systems therein, except that
          Lessee shall not be responsible for any damage due to ordinary
          wear, tear, deterioration, Lessor's acts, damage by war or damage
          due to nuclear hazards.

     (c)  Any damage, excessive wear, tear or deterioration caused by
          Lessor shall be repaired by Lessor at its cost within a
          reasonable time following the occurrence thereof and if Lessor
          does not make the necessary repairs or is not proceeding, in good
          faith, to do so after being notified in writing by Lessee of any
          such damage, Lessee may have such repairs made and may deduct the
          reasonable cost thereof from any rental payable to Lessor.

5.   UTILITIES

     Lessee shall be responsible for payment of the cost of all utility
     services used by Lessee upon the leased premises and shall make the
     deposits required in that connection where necessary.

6.   INSPECTION

     Lessor may enter the leased premises during business hours for any
     purpose connected either with the performance of its obligations
     hereunder, in the exercise of its governmental functions or to
     determine the condition of the leased premises from the standpoint of
     safety.

7.   ACCESS TO PREMISES

     Lessee shall have full and unrestricted access to and egress from the
     leased premises. In a manner consistent with Lessee's operation of its
     facilities, this privilege extends to Lessee's employees, customers,
     guests, and invitees as well as to Lessee's suppliers of materials and
     furnishers of service, its or their equipment, vehicles, machinery and
     other property.

8.   TAXES

     Lessee shall be responsible for the payment of all taxes on any
     equipment, inventory, and movable fixtures and furniture that Lessee
     places on the leased premises.

9.   INSURANCE

     During the primary term of this Lease or any extension hereof, Lessee
     shall comply with the following insurance requirements: 

     (a)  Lessee  shall  procure and maintain  fire and  extended  coverage
          insurance on the facilities located on the leased premises, in an
          amount to be agreed upon between Lessee and Lessor's  Director of
          Aviation,  but in no event  shall the amount of  coverage  on the
          existing  facilities  (excluding the Cargo Building when removed)
          be more  than the  reasonable  cost to  replace  them in the same
          condition as that on the date of execution hereof.

     (b)  Lessee shall maintain liability  insurance in the minimum amounts
          of $100,000 for each  person;  $1,000,000  for each  accident and
          $1,000,000 for property damage.

     (c)  Not later than the date of Lessee's occupancy  hereunder,  Lessee
          shall  provide  Lessor  with  appropriate   certificates  of  the
          required  insurance,  with a company or companies  acceptable  to
          Lessor,  evidencing  the  coverage  that  is in  effect  and  all
          policies of such insurance  shall name Lessor as  co-insured,  as
          its  interest may appear.  Each policy shall  provide that Lessor
          shall  be  given  fifteen  (15)  days  prior  written  notice  of
          cancellation of material  alteration of the insurance  covered by
          such policy.  According  to Sections 1 and 2 of Chapter  XXIII of
          Lessor's Charter,  any person who may have a claim against Lessor
          must file a written notice thereof with the City Secretary within
          six  (6)  months  after  the  injury  or  damage  occurs,   which
          requirement  cannot be waived by Lessee's insurance carrier or by
          any of Lessor's officials or employees.

     (d)  Any sublessee of the leased premises or of any part thereof shall
          be  required  by Lessee to  maintain  similar  fire and  extended
          coverage and liability insurance during the term of the sublease.

10.  LIENS

     (a)  Lessee  shall cause to be removed any and all liens of any nature
          arising  out  of  construction  performed  by it or  any  of  its
          contractors or  subcontractors  on the leased premises or arising
          out of the performance of any work or labor by it or them, or the
          furnishing  of any  material  to it or  them  for  use in  making
          improvements on said leased premises.

     (b)  In addition to the statutory  landlord's lien,  Lessor shall have
          at all times a valid  contractual lien for all rent and any other
          sums of  money  becoming  due  hereunder  from  Lessee,  upon all
          equipment,  fixtures,  furniture,  and other personal property of
          Lessee (excluding motor vehicles or aircraft) situated in or upon
          the  leased  premises,  subject  only to the rights of holders of
          vendor's and/or initial  mortgage liens thereon,  with respect to
          which Lessee,  upon request,  shall furnish Lessor evidence as to
          what property is so encumbered.  If there are rent arrearages, no
          property of Lessee not so subject to rights of prior  lienholders
          shall be removed by Lessee from the leased  premises  without the
          consent of Lessor's  Director of  Aviation  or his  successor  in
          function  until  such  arrearages  in rent as well as any and all
          other sums of money then due Lessor  hereunder  shall  first have
          been paid and discharged.

     (c)  Upon the occurrence of any of default (as hereafter specified) by
          Lessee,  Lessor may, in addition to any other  remedies  provided
          herein  or by law,  enter  upon  the  leased  premises  and  take
          possession  of any and all  equipment,  fixtures,  furniture  and
          other personal  property of Lessee situated on the premises,  not
          subject to rights of prior  lienholders and without liability for
          trespass or  conversion,  sell the same with or without notice at
          public or private sale,  with or without  having such property at
          the sale,  at which  Lessor or its  assignees  may  purchase  the
          property  and  apply  the  proceeds  therefrom,  less any and all
          expenses  connected with the taking of possession and sale of the
          property,  as a credit  against any sums due by Lessee to Lessor.
          Any surplus  shall be paid to Lessee and Lessee agrees to pay any
          deficiency forthwith.

     (d)  Lessee  shall not place on the  leased  premises  any  furniture,
          fixtures,  equipment or improvements  which would be subject to a
          lien of higher or equal  dignity that Lessor's  landlord's  lien,
          with the  exception  of vendor's  liens and/or  initial  mortgage
          liens.

11.  TERMINATION BY LESSOR

     Lessor reserves the right to terminate this Lease before the end of
     the primary or any extended term hereof if any of the following acts
     of default should occur:

     (a)  Lessee shall fail to make any payment due Lessor under this Lease
          on the date that same is due and such failure shall continue for
          a period of ten (10) days after receipt of written notice from
          Lessor advising of such failure. Such notice, if the failure
          remains uncorrected, shall be sufficient notice of termination of
          this Lease by Lessor.

     (b)  Lessee shall fail to comply with any term, condition or covenant
          of this Lease, other than one requiring payment to be made when
          due, and shall not have cured such failure within thirty (30)
          days after receipt of written notice from Lessor, or if such
          failure cannot reasonably be cured within the said thirty (30)
          day period and Lessee shall not have commenced to cure such
          failure within said thirty (30) days and shall not thereafter,
          with reasonable diligence and good faith, proceed to cure such
          failure.

     (c)  Lessee either shall become insolvent, shall make a transfer in
          fraud of creditors, shall make an assignment for the benefit of
          creditors, or shall have appointed a receiver or trustee for all
          or on substantially all of the assets of Lessee.

     (d)  Lessee shall file a voluntary petition under any section or
          chapter of the National Bankruptcy Act, as amended, or under any
          similar law or statute of the United States or any State thereof;
          or an involuntary petition in bankruptcy is filed against Lessee
          and is not dismissed within sixty (60) days after such filing.

     (e)  The management and/or ownership of Lessee should substantially
          change to such an extent as to result in unsatisfactory
          performance under this Lease.

     Should Lessor exercise its right in this Section, One Aviation shall
     be so notified.

12.  REMEDIES

     Upon the occurrence of any one of the acts of default giving Lessor
     the right to terminate this Lease, Lessor shall have the option to
     pursue the following remedy without any notice or demand other than as
     required in Section II.11 above. To terminate this Lease, in which
     event Lessee shall immediately surrender the leased premises to
     Lessor, and if Lessee fails so to do, Lessor may, without prejudice to
     any other remedy which it may have for possession or arrearages in
     rent, enter upon and take possession of the leased premises and expel
     or remove Lessee and any other person who may be occupying said
     premises or any part thereof, by force if necessary, without being
     liable to Lessee for prosecution or any claim for damages therefor.

     Lessor's pursuit of the foregoing remedy shall not preclude pursuit of
     any of the other remedies herein provided or any other remedies
     provided by law, nor shall pursuit of any remedy herein provided
     constitute a forfeiture or waiver of any rent due Lessor or of any
     damages accruing to Lessor by reason of the violation of any of the
     terms, conditions and convenants herein contained. If legal action is
     required to enforce any of such remedies, Lessor shall also be
     entitled to reasonable attorney's fees.

13.  TERMINATION BY LESSEE

     Before the end of either the primary term or any extension hereof,
     Lessee may terminate this Lease and any or all of its obligations
     hereunder at any time that Lessee is not in default in the payment of
     any amount due Lessor, by giving Lessor sixty (60) days written notice
     upon or after the happening of any one of the following events:

     (a)  The issuance by any court of competent jurisdiction of any order
          preventing or restraining the use of Love Field Airport for the
          purposes intended, the same apparently to remain in force and
          effect for a period of ninety (90) consecutive days or more. For
          that period of time that such order so preventing or restraining
          the use of Love Field is in effect prior to Lessee's termination
          of this Lease, the rental required of Lessee shall be abated.

     (b)  The assumption by the United States Government or any agency or
          instrumentality thereof of the operation, control or use of Love
          Field for National defense in such a manner as to preclude
          Lessee, for a period of ninety (90) consecutive days or more,
          from using such airport in the conduct of its business. Lessor
          shall not be liable to Lessee if the latter is so dispossessed,
          but for any time that such takes place prior to Lessee's
          termination of this Lease, the rental required of Lessee shall be
          abated.

     (c)  A material default on the part of the Lessor to meet and observe
          any of the covenants herein contained, if such default has
          continued for a period of sixty (60) days or more after written
          notice to Lessor by Lessee, unless Lessor has begun, and is
          continuing, in good faith, to remedy the default in such
          interval. The rental required of Lessee shall abate during the
          entire period when Lessor has committed such material default and
          if legal action is required to remedy such default, Lessee shall
          be entitled to reasonable attorney's fees in addition to any
          judgment, order, or award entered for Lessee.

     (d)  In the event the premises, existing facilities or Lessee's
          leasehold improvements, or any part thereof, are rendered wholly
          or partially untenantable for reasons other than obsolescence,
          acts or omissions of Lessee, its officers, employees, agents,
          guests, patrons, invitees, suppliers of materials or furnishers
          of services, and such remain untenantable for a period of sixty
          (60) consecutive days or more. The rental required of Lessee
          shall abate during the entire period of untenantablity.

     (e)  This Lease may, at Lessee's option, be terminated upon either
          Parcel A, B or both, at any time prior to June 1, 1978, without
          future liability, if at any time prior to the date of termination
          it appears to Lessee that either the Jetrail owned by BRANIFF
          AIRWAYS, INCORPORATED on Parcel B has not been or will not
          shortly be removed, Lessor has not approved plans for the
          construction of Lessee's facility on Parcel B, or any
          representation of Lessor herein is other than as stated.

14.  NO WAIVER OF RIGHT TO DECLARE FORFEITURE

     Any failure or neglect of the Lessor or Lessee at any time to declare
     a forfeiture of this Lease for any breach or default whatsoever
     hereunder shall not be taken or considered as a waiver of it rights
     thereafter to declare a forfeiture for a like or other succeeding
     breach or default.

15.  LESSEE'S RIGHT TO REMOVE PROPERTY

     Lessee shall be entitled, during the primary term of this Lease and

          claims of any character, name, or description brought for or on
          account of any injury, death or damage received or sustained by
          any person or property as a result of Lessee's conduct of any
          activity or operation on or in connection with the leased
          premises. Finally, the Lessee shall pay any judgments, together
          with costs, which may be obtained against the Lessor or any of

          agents, or employees and Lessor shall indemnify, defend and hold
          harmless Lessee, its directors, officers, employees and agents
          from and against any such injury or death or damage.

     (d)  The provisions of this Section which apply to Lessee shall also
          apply to any party holding by, through, or under Lessee.

18.  ASSIGNMENT AND SUBLEASE

     (a)  Lessee shall not assign this Lease in whole or in part, nor
          sublease all or any part of the leased premises, without the
          prior written approval of Lessor, acting through its Director of
          Aviation, which approval shall not be unreasonably withheld.
          (Such restrictions shall not apply if the assignee of sublessee
          is a subsidiary, affiliated or successor corporation of Lessee.)

     (b)  In the event that Lessee subleases all or any part of the leased
          premises, having obtained Lessor's approval, Lessee shall remain
          fully obligated for payment of rent, which shall continue to be
          billed to Lessee, and for the performance of the other convenants
          herein made by Lessee. Likewise, with respect to any assignment
          of this Lease (other than to an affiliated, subsidiary or
          successor corporation), Lessee's obligations shall continue in
          effect unless Lessor, by resolution of its City Council, approves
          the assignment and authorizes Lessee's release.

     (c)  Lessor shall not transfer or assign this Lease without the prior
          written approval of Lessee, except to a political subdivision of
          the State of Texas, and then only if such political subdivision
          assumes the obligations of Lessor hereunder.

19.  RIGHT OF FIRST REFUSAL

     Lessor hereby grants to Lessee a right of first refusal to lease all
     or any part of the real estate and any improvements thereon (called
     Parcels "C", "D" and "E"), constituting approximately 129,565 square
     feet within the boundaries of Love Field in the City and County of
     Dallas, State of Texas which is more particularly described on EXHIBIT
     C which is attached hereto and made a part hereof for all purposes.
     Should Lessor locate a third party desirous of leasing all or any part
     of Parcels C, D or E, Lessor shall first offer to lease such property
     to Lessee at the same rental rate and for the same lease term as
     offered by the third party. Lessee shall have ten (10) days after
     receipt of written notice from Lessor advising of such third party
     offer in which to exercise its rights to lease the premises. If Lessee
     leases the premises, the provisions of this Lease shall be applicable
     except for the rental and the term of such leasing.

     Upon Lessee's failure to exercise this right to lease the property,
     Lessor may lease it to such third party at the same rental rate and
     for the same lease term offered to Lessee. This right of first refusal
     shall never be extinguished by Lessee's failure to exercise it at any
     time. During the initial term or any extension of this Lease, provided
     that Lessee is not in default of any provision hereof, Lessee's right
     of first refusal as to Parcels C, D or E shall be renewed after each
     vacation of the property by a third party and be extended by Lessor to
     Lessee prior to Lessor's entry into each future lease upon such
     property with any third party.

20.  NONDISCRIMINATION

     Lessor and Lessee hereby convenant and agree, as a condition of this
     Lease, that they will take all necessary action to insure that, in
     connection with any work or activities conducted under this Lease,
     neither they, their agents and employees, nor any of their
     consultants, their agents and employees, will directly or through
     contractual or other arrangements, on the grounds of race, color,
     religion, national origin or sex, discriminate in the treatment or
     employment of any individual or groups of individuals.

21.  SIGNS

     (a)  All exterior signs shall comply with the pertinent City
          ordinances, and also shall be approved by Lessor's Director of
          Aviation. Unless otherwise specifically authorized, they shall
          conform in general appearance to the existing signs displayed at
          Love Field.

     (b)  Directional entrance and exit signs erected by Lessee shall not
          exceed 18 inches in width and 36 inches in length. Except where
          Lessor's Director of Aviation has given his prior written
          consent, any other sign erected by Lessee shall not exceed 5 feet
          in width and 8 feet in length.

     (c)  Upon the expiration or termination of this Lease, Lessee shall
          remove, obliterate or paint out, as required by Lessor's Director
          of Aviation, any and all signs and advertising on the leased
          premises if pertaining to Lessee, and in this regard, Lessee
          shall restore the premises to the same condition as prior to the
          placement thereon of any signs or advertising. In the event that
          Lessee fails to remove, obliterate or paint out each and every
          sign or advertisement of Lessee, Lessor's Director of Aviation
          may, at his option, have the necessary work performed at the
          expense of Lessee and the charge therefor shall be paid by Lessee
          to Lessor upon demand.

22.  GOVERNMENTAL REQUIREMENTS - RULES AND REGULATIONS

     (a)  Lessee agrees to obtain, from all governmental authorities having
          jurisdiction, all licenses, certificates and permits necessary
          for the conduct of its operations and to keep them current.

     (b)  In operating the leased premises, Lessee agrees to comply with
          the applicable lawful provisions of Federal and State laws and
          Ordinances of the City of Dallas.

     (c)  Lessor has established, and may, from time to time, establish,
          rules and regulations pertaining to Love Field. Lessee covenants
          to observe all such lawful rules and regulations. If such rules
          or regulations contravene any provision of this Lease or
          interfere or prevent Lessee's enjoyment and use of the leased
          premises, Lessee may, at its option, terminate this Lease.

23.  VENUE

     Venue of any action brought under this Lease shall be in Dallas
     County, Texas, exclusively.

amendments thereto shall continue in full force and effect and this
Amendment, along with the original Lease dated January 25, 1978 and all

Re:   Exercise of 5-year Option to Extend Lease
      Parcels A & B

Dear Mr. Nelson:

We are in receipt of your letter dated November 5, 1997 regarding rental
rates for the 5-year option period to extend the lease on Parcels A & B
beginning February 1, 1998.

The current prevailing rates for similar facilities at Dallas Love Field
are $0.26 per square foot per year for improved ground (ramp) and $2.24 per
square foot for hangar/shop space.

Enclosed is a copy of our most recent airport survey regarding ground
rental rates. Based on the average of the various rental rates, we believe
an increase to $0.26 per square foot for improved ground is fair and
equitable for the upcoming option period. Similarly, the current rate of
$2.24 per square foot is in line with the prevailing rate at the Airport.
The following outlines the proposed rental to be paid for the 5-year option
period beginning February 1, 1998:

                                  --------

          THIS SUBLEASE (the  "Sublease"),  made and entered into as of the

75234-0145 ("Tenant"),

                              WITNESSETH: THAT

          WHEREAS,  Landlord is the lessee  under that  certain  Love Field
Terminal  and Air Cargo  Facility  Lease and  Agreement  dated May 1, 1967,
covering the parcels of land located  within the  boundaries  of Love Field
Airport  and shown on Exhibit A attached  hereto (the  "Land")  between The
City of Dallas as landlord ("Ground  Lessor") and Landlord  (formerly known
as Braniff Realty Company) as tenant, as amended (such ground lease, as now
or  hereafter  from  time to time  amended,  is  referred  to herein as the
"Ground Lease");

          WHEREAS,  Tenant  desires to lease  from  Landlord  and  Landlord
desires  to  lease  to  Tenant a  certain  portion  of the Land in order to
construct a facility  thereon subject to and upon the terms,  covenants and
conditions set forth herein;

          WHEREAS,  Landlord and Tenant are entering into that certain Fuel
Sales   Agreement  of  even  date  hereof  (the  "Fuel  Sales   Agreement")
concurrently with and in consideration of the execution of this Sublease;

          NOW, THEREFORE,  Landlord and Tenant hereby covenant and agree as
follows:

     1.   Premises.

          1.1  Premises.  Upon and  subject  to the  terms,  covenants  and
conditions  hereafter  set forth,  Landlord  hereby  exclusively  leases to
Tenant  and  Tenant  hereby  leases  from  Landlord   those  premises  (the
"Premises")  consisting of a portion of the Land which is identified as the
"Lease Area" on Exhibit B attached  hereto.  Tenant shall, at its sole cost
and expense,  construct or cause to be constructed,  a facility on the Land
(the  "Building")  in  accordance  with the  terms and  provisions  of this
Sublease.  (The  Building and any and all other  buildings,  structures  or
other  improvements  on the Land shall be  collectively  referred to as the
"Improvements"  ). The  purpose  of  Exhibit  B is to show the  approximate
location of  Tenant's  Building  only,  and is not meant to  constitute  an
agreement as to the  construction of Tenant's  Building,  the rentable area
thereof or the specific location of the common areas or elements thereof.

          1.2 Square  Footage.  Landlord and Tenant agree that the rentable
area of the Premises is approximately 85,000 square feet, and further agree
that following the completion of Tenant's Building as provided in Article 7
hereof,  the actual square  footage of the Premises shall be calculated and
agreed upon in writing by the Landlord and Tenant.

     2.   Term.

          2.1 Initial Term.  The Premises are leased for a term of ten (10)
years (the  "Initial  Term"),  commencing  as of the date this  Sublease is
fully  executed by both parties and consented to by the City of Dallas (the
"Commencement  Date") and  expiring  at 11:59 p.m.  on the day  immediately
preceding the tenth (10th)  anniversary of the date of execution  hereof by
both parties,  subject to the rights of Tenant to extend the term hereof as
provided  herein,  or such earlier date on which this  Sublease  terminates
pursuant to the terms hereof (the "Expiration  Date").  Tenant's obligation
to pay Rent (as defined in Article 3)  pursuant  to Article 3 hereof  shall
begin on a date which is six months after the Commencement Date.

          2.2 Extension Options. Tenant shall have the option to extend the
term of this  Sublease for up to five (5)  consecutive  renewal  terms (the
"Extension  Terms").  The first four (4)  Extension  Terms shall consist of
five (5) years each and the fifth (5th)  consecutive  Extension  Term shall
consist of four (4) years. Tenant may exercise the Extension Options on the
following terms and conditions:

                    (a)  Provided  that  Tenant is not in default of any of
          the terms,  covenants or  conditions  of this  Sublease or of the
          Fuel Sales Agreement, Tenant may elect, upon written notice given
          to Landlord on or before the date which is seven (7) months prior
          to  the  Expiration  Date,  to  extend  the  Term  hereof  for an
          additional period of five (5) years (the "First Extension Term"),
          commencing  upon the first (lst) day  immediately  following  the
          Expiration  Date.  If Tenant  fails to timely elect to extend the
          Term  hereof  as  provided  in  this   Section   2.2(a),   Tenant
          conclusively  shall be deemed to have  waived its right to extend
          the Term hereof for the First Extension Term.  After the election
          by Tenant to extend  the Term  hereof  pursuant  to this  Section
          2.2(a),  each  reference to the "Term" hereof shall mean the term
          of this Sublease as it has been  extended by the First  Extension
          Term,  and each reference to the  "Expiration  Date" hereof shall
          mean  the  day   immediately   preceding  the  fifteenth   (15th)
          anniversary   date  of  the   Commencement   Date   (unless   the
          Commencement Date is a day other than the first day of a calendar
          month,  in which  event  the  Expiration  Date  shall be the date
          fifteen  (15)  years  after  the last day of the  calendar  month
          following  the  calendar  month in which  the  Commencement  Date
          occurs),  or such earlier date on which this Sublease  terminates
          pursuant to the terms hereof. The precise  agreements,  terms and
          conditions  hereof  shall  remain  in  effect  and be  applicable
          throughout the First Extension Term.

                    (b) Provided  that Tenant (i) has timely  exercised its
          option to extend this Sublease for the First  Extension Term, and
          (ii)  is  not in  default  of any  of  the  terms,  covenants  or
          conditions  of this  Sublease  or of the  Fuel  Sales  Agreement,
          Tenant may elect,  upon  written  notice  given to Landlord on or
          before the date which is seven (7) months prior to the Expiration
          Date (as  extended by the First  Extension  Term),  to extend the
          Term  hereof  for an  additional  period of five (5)  years  (the
          "Second  Extension  Term"),  commencing  upon the first (1st) day
          immediately  following  the  Expiration  Date (as extended by the
          First  Extension  Term).  If Tenant fails to timely  exercise its
          option to extend this Sublease for the First  Extension  Term, or
          to  timely  elect  to  extend  the  Term  hereof  for the  Second
          Extension  Term  as  provided  in  this  Section  2.2(b),  Tenant
          conclusively  shall be deemed to have  waived its right to extend
          the Term hereof for the Second Extension Term. After the election
          by Tenant to extend  the Term  hereof  pursuant  to this  Section
          2.2(b),  each  reference to the "Term" hereof shall mean the term
          of this Sublease as it has been  extended by the First  Extension
          Term and the Second  Extension  Term,  and each  reference to the
          "Expiration Date" hereof shall mean the day immediately preceding
          the twentieth (20th)  anniversary  date of the Commencement  Date
          (unless the  Commencement  Date is a day other than the first day
          of a calendar  month, in which event the Expiration Date shall be
          the date  twenty  (20) years  after the last day of the  calendar
          month following the calendar month in which the Commencement Date
          occurs),  or such earlier date on which this Sublease  terminates
          pursuant to the terms hereof. The precise  agreements,  terms and
          conditions  hereof  shall  remain  in  effect  and be  applicable
          throughout the Second Extension Term.

                    (c) Provided  that Tenant (i) has timely  exercised its
          option to extend this Sublease for the First and Second Extension
          Terms, and (ii) is not in default of any of the terms,  covenants
          or conditions  of this  Sublease or of the Fuel Sales  Agreement,
          Tenant may elect,  upon  written  notice  given to Landlord on or
          before the date which is seven (7) months prior to the Expiration
          Date (as extended by the First and Second  Extension  Terms),  to
          extend the Term hereof for an additional period of five (5) years
          (the "Third Extension Term"), commencing upon the first (1st) day
          immediately  following  the  Expiration  Date (as extended by the
          First and  Second  Extension  Terms).  If Tenant  fails to timely
          exercise  its  option to extend  this  Sublease  for the First or
          Second  Extension  Terms,  or to timely  elect to extend the Term
          hereof for the Third  Extension  Term as provided in this Section
          2.2(c),  Tenant  conclusively  shall be deemed to have waived its
          right to extend  the Term  hereof for the Third  Extension  Term.
          After the  election by Tenant to extend the Term hereof  pursuant
          to this Section 2.2(c), each reference to the "Term" hereof shall
          mean the term of this  Sublease  as it has been  extended  by the
          First,  Second and Third Extension  Terms,  and each reference to
          the  "Expiration  Date"  hereof  shall  mean the day  immediately
          preceding  the  twenty-fifth   (25th)  anniversary  date  of  the
          Commencement  Date (unless the  Commencement  Date is a day other
          than the  first  day of a  calendar  month,  in which  event  the
          Expiration  Date shall be the date  twenty-five  (25) years after
          the last day of the calendar  month  following the calendar month
          in which the Commencement  Date occurs),  or such earlier date on
          which this Sublease  terminates pursuant to the terms hereof. The
          precise  agreements,  terms and conditions hereof shall remain in
          effect and be applicable throughout the Third Extension Term.

                    (d) Provided  that Tenant (i) has timely  exercised its
          option to extend this  Sublease  for the First,  Second and Third
          Extension  Terms, and (ii) is not in default of any of the terms,
          covenants  or  conditions  of this  Sublease or of the Fuel Sales
          Agreement,  Tenant  may  elect,  upon  written  notice  given  to
          Landlord on or before the date which is seven (7) months prior to
          the Expiration  Date (as extended by the First,  Second and Third
          Extension  Terms),  to extend the Term  hereof for an  additional
          period  of  five  (5)  years  (the  "Fourth   Extension   Term"),
          commencing  upon the first (1st) day  immediately  following  the
          Expiration  Date (as  extended  by the  First,  Second  and Third
          Extension  Terms).  If Tenant fails to timely exercise its option
          to extend this Sublease for the First,  Second or Third Extension
          Term, or to timely elect to extend the Term hereof for the Fourth
          Extension  Term as  provided  in  this  Section  2.02(d),  Tenant
          conclusively  shall be deemed to have  waived its right to extend
          the Term hereof for the Fourth Extension Term. After the election
          by Tenant to extend  the Term  hereof  pursuant  to this  Section
          2.02(d),  each reference to the "Term" hereof shall mean the term
          of this  Sublease as it has been  extended by the First,  Second,
          Third and  Fourth  Extension  Terms,  and each  reference  to the
          "Expiration Date" hereof shall mean the day immediately preceding
          the thirtieth (30th)  anniversary  date of the Commencement  Date
          (unless the  Commencement  Date is a day other than the first day
          of a calendar  month, in which event the Expiration Date shall be
          the date  thirty  (30) years  after the last day of the  calendar
          month following the calendar month in which the Commencement Date
          occurs),  or such earlier date on which this Sublease  terminates
          pursuant to the terms hereof. The precise  agreements,  terms and
          conditions  hereof  shall  remain  in  effect  and be  applicable
          throughout the Fourth Extension Term.

                    (e) Provided  that Tenant (i) has timely  exercised its
          option to extend this Sublease for the First,  Second,  Third and
          Fourth  Extension Terms, and (ii) is not in default of any of the
          terms,  covenants or  conditions  of this Sublease or of the Fuel
          Sales Agreement,  Tenant may elect,  upon written notice given to
          Landlord on or before the date which is seven (7) months prior to
          the Expiration Date (as extended by the First,  Second, Third and
          Fourth  Extension  Terms),  to  extend  the  Term  hereof  for an
          additional period of four (4) years (the "Fifth Extension Term"),
          commencing  upon the first (1st) day  immediately  following  the
          Expiration  Date (as  extended  by the First,  Second,  Third and
          Fourth Extension  Terms).  If Tenant fails to timely exercise its
          option to extend this  Sublease for the First,  Second,  Third or
          Fourth  Extension  Term,  or to timely  elect to extend  the Term
          hereof  pursuant to this  Section  2.02(e),  Tenant  conclusively
          shall be deemed  to have  waived  its  right to  extend  the Term
          hereof for the Fifth Extension Term. After the election by Tenant
          to extend the Term hereof pursuant to this Section 2.02(e),  each
          reference  to the  "Term"  hereof  shall  mean  the  term of this
          Sublease  as it has been  extended by the First,  Second,  Third,
          Fourth  and  Fifth  Extension  Terms  and each  reference  to the
          "Expiration Date" hereof shall mean the day immediately preceding
          the thirtieth (30th)  anniversary  date of the Commencement  Date
          (unless the  Commencement  Date is a day other than the first day
          of a calendar  month, in which event the Expiration Date shall be
          the  date  thirty-four  (34)  years  after  the  last  day of the
          calendar month in which the  Commencement  Date occurs),  or such
          earlier date on which this  Sublease  terminates  pursuant to the
          terms hereof. The precise agreements, terms and conditions hereof
          shall  remain in effect and be  applicable  throughout  the Fifth
          Extension Term.

     3.   Base Rent; Additional Charges.

          3.1 Base Rent.  Tenant  shall pay to Landlord  during the Initial
Term  annual  base  rental in the amount of  fifty-five  cents  ($0.55) per
square  foot,  for a total  annual  base  ground  rental  of  approximately
Forty-Six  Thousand  Seven Hundred Fifty  Dollars  ($46,750.00)  subject to
adjustment as provided in Section 1.2 (the "Base Rent"), which sum shall be
adjusted as hereinafter  provided,  and shall be payable by Tenant in equal
consecutive   monthly   installments   of  Three   Thousand  Eight  Hundred
Ninety-Five  ($3,895.83)  Dollars  and  Eighty-Three  Cents (or such  other
amount as is equal to one-twelfth (1/12th) of the then prevailing Base Rent
hereunder)  on or before the first day of each month,  in  advance,  at the
address  specified  for  Landlord  in  Article  21 or such  other  place as
Landlord shall designate, without any prior demand therefor and without any
abatement, deductions or setoff whatsoever. If the Commencement Date should
occur on a day  other  than  the  first  day of a  calendar  month,  or the
Expiration Date should occur on a day other than the last day of a calendar
month,  then the rental for such fractional  month shall be prorated upon a
daily basis based upon a thirty (30) day  calendar  month.  Notwithstanding
the  foregoing,  no Base Rent shall be owed by Tenant for the first six (6)
months of the Initial Term.  Landlord and Tenant acknowledge that Base Rent
stated  herein is  calculated  based on an area of the  Premises  of 85,000
square feet.  Promptly following  completion of the Building,  Landlord and
Tenant shall  determine the actual  rentable square footage of the Premises
whereupon the Base Rent payable  hereunder  shall be adjusted  accordingly,
and Landlord and Tenant shall  execute a written  instrument  setting forth
the adjusted Base Rent, if applicable, for the Premises.

          3.2 City of Dallas  Adjustments.  Under  the  Ground  Lease,  the
Ground Lessor has the right,  from time to time, to increase the Landlord's
stated rental rate by  redetermining  the rental to be paid by the Landlord
as the sum of the following:

          (A)  An amount of rent that is determined by the prevailing  rent
               then being charged by the Ground Lessor,  subject to certain
               limitations,  with certain additional triennial  adjustments
               (the "Prevailing Rental Increment"); and

          (B)  Forty  Cents  ($.40)  per  annum  per  square  foot  of land
               contained  within  the  premises  (the   "Additional   Fixed
               Increment").

          It is  understood  and agreed by the Landlord and the Tenant that
the Base Rent in effect  hereunder  shall be increased  by each  Prevailing
Rental  Increment  (less the Base Rent  then in effect  hereunder)  that is
imposed as rent upon the  Landlord  by the Ground  Lessor  under the Ground
Lease, which increases hereunder shall be effective each and every time and
as and when each  Prevailing  Rental  Increment is imposed as rent upon the
Landlord by the Ground Lessor under the Ground Lease.

          It is  further  understood  and  agreed by the  Landlord  and the
Tenant that the Base Rent in effect hereunder shall not be increased by any
Additional Fixed Increment that is imposed as rent upon the Landlord by the
Ground Lessor under the Ground Lease.

          3.3 Rent Adjustments.  Commencing  January 1, 1993 and on January
1st of each year  thereafter,  subject to a maximum  adjustment  of no more
than seven  percent  (7%) per annum,  the Base Rent  shall be  adjusted  as
follows:

          PPI  Adjustment.  On  January  1st of each  year,  the Base  Rent
payable  hereunder shall be adjusted such that the Base Rent shall be equal
to the  greater of (i) the Base Rent in effect as of such  January  1st, or
(ii) the product of the sum of the initial Base Rent payable hereunder plus
all  adjustments  thereto on account of increases  announced by the City of
Dallas as provided in Section 3.2, multiplied by a fraction,  the numerator
of which is the PPI for the July  immediately  preceding  such January 1st,
and the  denominator  of which is the PPI for July of 1992. For purposes of
this  Sublease,  "PPI" shall mean the  Dallas-Fort  Worth,  Texas  Standard
Metropolitan  Statistical  Area Producers Price Index relative to aviation,
or equivalent  index, as published from time to time by the Bureau of Labor
Statistics,  United States  Department of Labor, or the generally  accepted
replacement or successor index.

          3.4 Additional Charges.  Tenant shall pay to Landlord all charges
and other amounts  whatsoever  payable by Tenant to Landlord as provided in
this  Sublease  including  the Exhibits  hereto  (collectively  "Additional
Charges" or "Additional Rent"), including,  without limitation, the charges
for Real  Estate  Taxes  provided  for in  Article 4 and Apron  Space  Rent
provided  for in Article  16, at the place  where the Base Rent is payable.
Landlord  shall  have the same  remedies  for a default  in the  payment of
Additional  Charges or  Additional  Rent as for a default in the payment of
Base Rent. As used herein, the term "Rent" shall mean the Base Rent and all
Additional Charges or Additional Rent.

          3.5 Late  Payments.  If Tenant  shall fail to pay any Rent within
ten (10)  days  after  the date the same is due and  payable,  such  unpaid
amounts shall be subject to a late payment charge equal to one and one-half
percent (1-1/2%) of such unpaid amounts in each instance. Such late payment
charge has been agreed upon by Landlord and Tenant, after negotiation, as a
reasonable estimate of the additional administrative costs and detriment to
Landlord's ability to meet its own obligations  relating to the Building in
a timely  manner  that will be incurred by Landlord as a result of any such
failure  by  Tenant,  the  actual  costs  thereof  in each  instance  being
extremely  difficult  if not  impossible  to  determine.  Such late payment
charge shall constitute  liquidated damages to compensate  Landlord for its
damages  resulting  from such  failure to pay and shall be paid to Landlord
together with such unpaid amounts.

     4.   Taxes.

          4.1  Definitions.  For purposes of this Article 4, the  following
terms shall have the meanings hereinafter set forth:

                    (a)  "Tenant's   Share"  shall  mean  _______   percent
          (____%).  Tenant's  Share  will be  computed  (and  filled in) by
          dividing  the actual total area of the Premises by the total area
          of the  Land  and,  in the  event  that  either  the  area of the
          Premises or the total area of the Land is changed, Tenant's Share
          will be  appropriately  adjusted as of the effective date of such
          change; and as to the Tax Year or Expense Year (as said terms are
          hereinafter defined) in which such change occurs,  Tenant's Share
          shall be  determined  on the basis of the  number of days  during
          such Tax Year and Expense Year at each such percentage.

                    (b) "Tax Year" shall mean each twelve (12)  consecutive
          month period commencing  January 1st of each year,  provided that
          Landlord,  upon  notice to  Tenant,  may change the Tax Year from
          time to time to any other  twelve (12)  consecutive  month period
          and, in the event of any such change, Tenant's Share of Taxes (as
          hereinafter  defined)  shall be  equitably  adjusted  for the Tax
          Years involved in any such change.

                    (c)  "Real   Estate   Taxes"   shall  mean  all  taxes,
          assessments,  fees,  impositions  and charges levied upon or with
          respect  to all or any part of the Land,  Building  and any other
          Improvements   located  thereon.   The  "Land",   "Building"  and
          "Improvements"   are  collectively   referred  to  as  the  "Real
          Property", which term shall also include any personal property of
          Tenant used in  connection  therewith.  Real  Estate  Taxes shall
          include,   without  limitation,   and  whether  now  existing  or
          hereafter enacted or imposed, all general real property taxes and
          general  and  special  assessments  (regardless  of the method of
          valuation  utilized by the taxing  authority in  determining  the
          amount  of any  such tax or  assessment),  all  charges,  fees or
          assessments,  whenever  arising or paid or  payable,  for or with
          respect to transit,  housing,  police, fire or other governmental
          services or purported benefits to or burdens  attributable to all
          or any part of the Real  Property  or any  personal  property  of
          Tenant used in connection therewith, all service payments in lieu
          of taxes,  and any tax,  fee,  imposition or excise on the act of
          entering  into this  Sublease  or any other lease of space in the
          Building,  or on the use or  occupancy  of all or any part of the
          Real  Property,  or on the rent  payable  under  any  lease or in
          connection  with the business of renting  space in the  Building,
          that are now or hereafter  levied or assessed against Landlord or
          Tenant or any part of the Real Property,  by the United States of
          America,  the State of Texas,  the County of Dallas,  the City of
          Dallas,  or  any  political   subdivision,   public  corporation,
          district  or other  political  or public  entity,  and shall also

          Estate   Taxes,   whether  or  not  now   customary   or  in  the
          contemplation  of the parties on the date of this Sublease.  Real
          Estate Taxes shall not include franchise,  transfer,  inheritance
          or capital stock taxes or income taxes measured by the net income

          in the  method  of  taxation,  any of such  taxes  is  levied  or
          assessed against Landlord or Tenant as a substitute for, or as an
          addition  to,  in whole  or in part,  any  other  tax that  would

          also include a prorated  portion (based on Tenant's Share) of the
          reasonable legal fees and other costs and disbursements  incurred

          or reduce Real Estate Taxes, provided,  Landlord has given Tenant
          prior notice of incurring such fees, costs and  disbursements and
          Tenant has provided Landlord with written approval.

          4.2 Payment of Taxes.

                    (a) Prior to Construction of Improvements. Tenant shall
          be obligated  to promptly  pay Tenant's  Share of the Real Estate
          Taxes, if any, for such Tax Year, or portion thereof,  during the
          Term of this Lease on or before the due date. Tenant will use its
          best efforts to obtain a separate tax bill for Tenant's  Share of
          the Real Estate Taxes. Tenant will send Landlord duplicate copies
          of all paid tax receipts.

                    (b) After Completion of  Improvements.  Upon completion
          of the  construction  of the  Improvements in accordance with the
          terms of this Lease,  title to the Improvements shall immediately
          vest  in the  City  of  Dallas.  It is the  understanding  of the
          parties  hereto  that the City will be exempt from the payment of
          any Real Estate Taxes relating to the Improvements.  Tenant shall
          be obligated to promptly pay Tenant's Share of Real Estate Taxes,
          if any, after the completion of the  Improvements  and conveyance
          to the City of Dallas on or before the due date,  including,  but
          not limited to, any taxes for Tenant's personal property.  Tenant
          will send Landlord duplicate copies of all paid tax receipts.

          4.3 Commencement  Date. If the Commencement Date shall occur on a
date other than the first day of a Tax Year,  Tenant's Share of Real Estate
Taxes for the Tax Year in which the  Commencement  Date occurs  shall be in
the proportion that the number of days from and including the  Commencement
Date  to  and  including  the  last  day of  the  Tax  Year  in  which  the
Commencement Date occurs bears to 365.

          4.4 Tax Reduction Proceedings.

                    (a)  Landlord  shall  have the right to  institute  tax
          reduction or other  proceedings to reduce the assessed  valuation
          of the Land,  Building or other  Improvements,  unless such Land,
          Building or other  Improvements are separately  assessed.  Should
          Landlord be  successful  in any such  reduction  proceedings  and
          obtain a rebate for periods during which Tenant has paid Tenant's
          Share of Real Estate Taxes,  Landlord shall,  after deducting its
          expenses  prorated  based on Tenant's  Share,  including  without
          limitation  reasonable  attorneys'  fees and  disbursements,  pay
          Tenant's Share of such rebate to Tenant (prorated for any partial
          year if appropriate).

                    (b) Tenant shall also have the right to  institute  tax
          reduction  or  other  proceedings  to  contest  the  legality  or
          validity of any tax  assessment  or other  imposition  that it is
          directly  or  indirectly  required  to pay under this  Article 4.
          Landlord agrees to execute and deliver such documents  evidencing
          Tenant's  right under this  Article 4 which may be  necessary  or
          helpful in any such context.  Tenant agrees to indemnify and hold
          Landlord  harmless  from any and all  liability,  cost,  expense,
          penalty or interest which may be assessed as a result of Tenant's
          actions hereunder,  and Tenant agrees to promptly pay any amounts
          which  become  due as a result  of a final  determination  of its
          contest.

          4.5 No Forfeiture.  Landlord's failure to prepare and deliver any
tax bill, notice or statement provided for in this Article 4, or Landlord's
or Tenant's  failure to make a demand,  shall not cause Landlord or Tenant,
as the case may be, to forfeit or surrender its right to collect any amount
which may  become  due to it under  this  Article  4.  Notwithstanding  the
foregoing,  Landlord agrees to use reasonable efforts to: (i) notify Tenant
before  filing a property  tax return or  responding  to any inquiry from a
taxing  authority  concerning  the  property  leased  hereunder;   or  (ii)
immediately upon receipt, forward to Tenant a copy of any tax assessment or
other tax related notification relating to the property leased.

Dallas Love Field Airport,  or (iii) the  occurrence of a material  default
under the Fuel Sales Agreement resulting in a termination thereof.

          (b) Validity.  In the event the Restrictive Covenant contained in
subparagraph  (a) above  shall be  adjudicated  by any  court of  competent
jurisdiction  to be partially or totally invalid or  unenforceable  for any
reason,  such covenant shall be deemed modified to the extent  necessary to
render it valid and  enforceable  under the laws of such  jurisdiction,  or
shall be excised from this Sublease, as circumstances may require, and said
subparagraph  (a),  subject  to such  modification  or  deletion,  shall be
enforced  to the  maximum  extent and scope  permitted  by the laws of such
jurisdiction.

          (c)  Remedies.  Landlord,  in addition  to all other  remedies to
which it may be entitled,  at law or in equity, in the event of a breach of
the Restrictive Covenant,  shall also be entitled, as a matter of right, to
injunctive relief in any court of competent jurisdiction.

provided that neither Ground Lessor nor such mortgagee or beneficiary shall

occurring prior to such  termination,  foreclosure or conveyance in lieu of
foreclosure, or be subject to any offsets,  counterclaims or defenses which
Tenant may be entitled to assert  against  Landlord or be bound by payments
by Tenant of Base Rent for more than one month in  advance  of the due date

shall notify  Tenant of any change or amendments to such Ground Lease prior
to the  effective  date  thereof,  or if that is not  possible,  as soon as
reasonably possible.  Tenant agrees to indemnify,  defend and hold Landlord
and its directors,  officers,  agents and employees harmless from any claim
or liability arising from Tenant's failure to comply with the provisions of
the  Ground  Lease.  Tenant  hereby  acknowledges  receipt of a copy of the
Ground Lease. Notwithstanding anything herein to the contrary, in the event
of a conflict  between the terms and  conditions  of the Ground  Lease,  as
amended,  and the terms and conditions of this  Sublease,  the Ground Lease
shall control.

          11.3  Ground   Lessor   Approval.   Landlord  and  Tenant  hereby
acknowledge that this Sublease is subject to the approval of Ground Lessor,
and it is further  acknowledged that nothing herein contained shall enlarge
or  extend  the   liabilities   and   obligations  of  the  Ground  Lessor.
Notwithstanding  anything  contained  herein to the  contrary,  the parties
hereto  shall  be bound  by all  terms  and  conditions  of this  Sublease,
including, without limitation, Tenant's obligation to pay rental hereunder,
pending receipt of approval by the Ground Lessor;  provided,  however, that
Landlord  shall not be liable or have any further  obligations to Tenant in
the event the Ground Lessor does not approve this Sublease.

          11.4   Expiration  of  Sublease   Agreement.   In  the  event  of
cancellation  or termination of the Ground Lease prior to the expiration of
the  Term  hereof,  or in the  event  of  the  surrender  thereof,  whether
voluntary,  involuntary, or by operation of law, or should Landlord fail to
exercise any of its extension  options  under the Ground Lease,  the Tenant
shall  make full and  complete  attornment  to the  Ground  Lessor  for the
balance  of the  term  of  this  Sublease,  upon  the  same  covenants  and
conditions as are contained  herein,  so as to establish  direct privity of
estate and contract between the Ground Lessor and the Tenant, with the same
force and effect as though this Agreement was originally made directly from
the Ground Lessor to the Tenant.  The Tenant shall make all Rental payments
thereafter directly to the Ground Lessor.

          11.5 Subordination to Mortgages. In addition to being subject and
subordinate  to the  Ground  Lease,  this  Sublease  shall be  subject  and
subordinate  at all times  to:  (a) the lien of any  mortgages  or deeds of
trust that may now exist or  hereafter  be executed in any amount for which
the ground leases or underlying  leases,  Building  rentals,  or Landlord's
interest or estate in any of said items is specified as security.  Landlord
shall use its best  efforts  to secure  in any such  mortgages  or deeds of
trust and in any such other ground leases or  underlying  leases a covenant
on the  part of the  mortgagees,  beneficiaries  or  ground  or  underlying
lessors  thereunder to recognize the interest of Tenant under this Sublease
in the event of any  foreclosure or conveyance in lieu of  foreclosure,  or
any  termination of any such ground or underlying  lease, if at the time of
any such event Tenant is not then in default hereunder. Notwithstanding any
recognition of this Sublease by any such mortgagees,  beneficiaries,  or by
Ground  Lessor or any  existing  mortgagee  or  beneficiary,  (i)  Tenant's
interest under this Sublease shall nevertheless be subject to the rights of
such  mortgagees  or  beneficiaries  or  Ground  Lessor  to  insurance  and
condemnation  proceeds  with  respect to the Real  Property,  (ii) any such
recognition  of Tenant's  interest  under this Sublease shall not result in
any  liability  or  responsibility  on the  part  of any  such  mortgagees,
beneficiaries  or Ground  Lessor,  for any past  defaults of Landlord,  the
prepayment of any Rent by Tenant,  any claim or setoff that Tenant may have
against  Landlord,  or any  obligations  of  Landlord  with  respect to the
construction  of the Building or the  Premises,  or any part  thereof,  and
(iii) no amendment of this Sublease shall be binding on any such mortgagees
or beneficiaries  or ground or underlying  lessors or Ground Lessor without
such party's written  consent.  Notwithstanding  the foregoing,  so long as
Tenant shall pay its Rent and perform all of its obligations hereunder,  no
such  mortgagee  or  beneficiary  shall  interfere  with  Tenant's  use and
occupancy of the Premises in accordance with the terms hereof.

          11.6 Self-Operating Provisions. The provisions of this Article 11
shall be self-operative and no further instrument shall be required. Tenant
covenants and agrees, however, to execute and deliver, promptly upon demand
by Landlord and in the form requested by Landlord, any additional documents
evidencing  the  subordination  of this Sublease with respect to the Ground
Lease or the lien of any such mortgages or deeds of trust.

     12.  Assignment and Subletting.

          12.1 Consent  Required.  Neither Tenant,  nor any other person or
entity  which at any time uses or  occupies,  or holds any interest in this
Sublease with respect to, all or any part of the Premises, whether acquired
directly or  indirectly  from  Tenant,  including  without  limitation  any
subtenant or subassignee and any person or entity acquiring any interest of
Tenant or any such other person or entity under this  Sublease  pursuant to
any   foreclosure   sale  or  conveyance  in  lieu  thereof   (collectively
"Transferor"), shall directly or indirectly, voluntarily or by operation of
law, sell,  assign,  encumber,  pledge or otherwise transfer or hypothecate
all or any part of its  interest in or rights with  respect to the Premises
or its leasehold or subleasehold  estate  (collectively,  "Assignment")  or
permit all or any portion of the  Premises  to be occupied by anyone  other
than  itself or sublet all or any  portion of the  Premises  (collectively,
"Sublease"),  without  Landlord's and Ground Lessor's prior written consent
in each instance as provided hereinbelow,  and each Transferor's  leasehold
estate  shall  consist only of the right to use and occupy the Premises (or
the portion  thereof covered by a Sublease) for its own purposes during the
term of its leasehold estate.

          12.2  Notice  of  Proposed  Transfer.  If  Tenant  or  any  other
Transferor  desires at any time to enter into an  Assignment or a Sublease,
it shall first give  written  notice to Landlord of its  intention to do so
(the "Notice of Proposed  Transfer"),  which  notice shall  contain (a) the
name  of  the  proposed  assignee,   subtenant  or  occupant  (collectively
"Transferee"),  (b) the nature of the proposed  Transferee's business to be
carried on in the  Premises,  (c) the terms and  provisions of the proposed
Assignment  or  Sublease,  and (d) the most recent  financial  statement or
other equivalent financial information  concerning the proposed Transferee.
In  addition,  Tenant  shall  provide  to  Landlord  such  other  financial
information  as Landlord may request  concerning  the proposed  Transferee.
Once given,  any such Notice of Proposed  Transfer shall be irrevocable for
such period of time as is permitted under Section 12.3 for Landlord to make
an election and for such election to become final.

          12.3  Landlord's  Electives.  At any time within twenty (20) days
after Landlord's receipt of any Notice of Proposed  Transfer,  Landlord may
by  written  notice  to Tenant or other  Transferor  elect to (a)  Sublease
itself  from  Tenant the portion of the  Premises  covered by the  Sublease
specified in the Notice of Proposed  Transfer,  or any portion thereof,  on
the terms and  conditions  set forth in the  Notice of  Proposed  Transfer,
except as otherwise  provided in Section 12.4 and Section 12.5, (b) consent
to  the  Sublease  or  Assignment,   or  (c)  disapprove  the  Sublease  or
Assignment.  Landlord  may elect the option in clause (a) above in its sole
and  absolute  discretion;  provided  that if  Landlord  does not elect the
option in clause (a), then Landlord agrees not to unreasonably withhold its
consent to the Sublease or  Assignment,  but in any event such  Sublease or
Assignment shall be subject to the provisions of Section 12.6.

          12.4 Takeback Space. In the event Landlord elects the options set
forth in Section 12.3(a) with respect to all or any portion of the Premises
(the "Takeback  Space"),  Tenant or other Transferor shall (a) at all times
provide without charge  reasonable and  appropriate  access to the Takeback
Space (if less than the entire Premises) and use of any common facilities.

          12.5  Landlord's  Rights.  If Landlord  elects to  Sublease  from
Tenant or other  Transferor as described in Section  12.3(a),  (a) Landlord
shall  have the  right to use the  Takeback  Space  for any  legal  purpose
consistent  with the Ground Lease,  as amended,  or this Sublease,  (b) the
rent  and any  other  charges  payable  by  Landlord  to  Tenant  or  other
Transferor  thereunder  shall be that set forth in the  Notice of  Proposed
Transfer,  (c)  Landlord  may  make  alterations  and  improvements  to the
Takeback Space as it shall elect and any such  alterations or  improvements
may be removed, in whole or in part, prior to or upon the expiration of the
Sublease,  provided that any damage or injury to the Takeback  Space caused
by such removal shall be repaired, and (d) Landlord shall have the right to
further  assign or sublease  the  Takeback  Space to any party  without the
consent of Tenant or other Transferor, provided, that Landlord shall be and
remain  liable  to Tenant  for the  payment  of the rent and other  charges
payable by Landlord  hereunder and for the performance of all of the terms,
covenants,  conditions and agreements  relating to the Takeback Space to be
performed by Landlord.

          12.6 Conditions of Assignment or Sublease.  If Landlord  consents
to any Sublease or Assignment as set forth in Section 12.3(b):

                    (a) Tenant or other  Transferor may  thereafter  within
          ninety  (90)  days  after  Landlord's  consent  enter  into  such
          Assignment  or  Sublease,  but only  with the  party and upon the
          specific terms and conditions set forth in the Notice of Proposed
          Transfer;

                    (b) In the  case of a  Sublease,  Tenant  shall  pay to
          Landlord monthly,  together with the monthly installments of Rent
          hereunder,  fifty percent (50%) of the excess, if any, of any and
          all sums  actually  paid to or on behalf  of  Tenant  under or in
          connection with such Sublease over (i) the Rent payable by Tenant
          under this Sublease for the space covered by such Sublease (which
          shall be a pro rata portion of the Rent payable  hereunder in the
          case of a Sublease of a portion of the  Premises),  (ii) costs of
          any additional leasehold improvements made to the space sublet in
          excess of the cost to  Landlord of any  Landlord's  Work which is
          not  billed  to and paid for by  Tenant,  allocated  to the space
          sublet (on a per rentable  square foot basis),  and provided that
          such  leasehold  improvement  costs shall be  amortized  over the
          shorter of the useful life of such leasehold  improvements or the
          remaining term of this Sublease as of the date of installation of
          such leasehold improvements,  and (iii) Tenant's reasonable costs
          incurred   in   subleasing   the  space,   including   reasonable
          commissions and reasonable  legal fees and expenses,  or incurred
          in  enforcing  the terms of the Sublease or pursuing any remedies
          against  the  subtenant,  including  reasonable  legal  fees  and
          expenses, provided that Tenant shall furnish Landlord with copies
          of bills  or  other  similar  documentation  substantiating  such
          costs; and

                    (c) Such Sublease or Assignment shall be subject to and
          in full  compliance  with all of the terms and provisions of this
          Sublease;  and Landlord's  consent to such Sublease or Assignment
          shall not be  construed as a consent to any terms  thereof  which
          are  inconsistent  or in conflict  with any of the  provisions of
          this Sublease unless and only to the extent that Landlord in such
          consent  specifically  agrees  in  writing  to be  bound  by such
          inconsistent or conflicting terms.

          12.7 No Release of Tenant;  No Waiver.  No consent by Landlord to
any  Assignment  or Sublease by Tenant or other  Transferor  shall  relieve
Tenant or other  Transferor of any  obligation to be performed by Tenant or
such  Transferor  under this  Sublease,  arising  before the  Assignment or
Sublease,  nor  shall  it  relieve  Tenant  or  other  Transferor  from the
obligation  to  obtain  Landlord's  express  written  consent  to any other
Assignment  or  Sublease.  Any  Assignment  or  Sublease  that  is  not  in
compliance  with  this  Article  12 shall be void  and,  at the  option  of
Landlord,  shall  constitute  a  material  default  by  Tenant  under  this
Sublease. The acceptance of any Rent by Landlord from a proposed Transferee
shall not constitute  consent to such Assignment or Sublease by Landlord or
a recognition  of any  Transferee or a waiver by Landlord of any failure of
Tenant or other Transferor to comply with this Article 12.

          12.8  Direct or  Indirect  Sales.  Subject to the  provisions  of
Section 12.3,  any direct or indirect sale or other  transfer of a majority
of the  voting  stock of  Tenant  or other  Transferor,  if  Tenant or such
Transferor  is a  corporation,  or any  direct  or  indirect  sale or other
transfer of a majority of the general  partnership  interests  in Tenant or
other Transferor,  if Tenant or other Transferor is a partnership,  whether
any  such  sale  or  transfer  shall  occur  as the  result  of any  single
transaction or event or any series of transactions  or events,  shall be an
Assignment for purposes of this Article 12 if this Sublease constitutes all
or  substantially  all of  the  real  estate  assets  of  Tenant  or  other
Transferor.  In addition,  any direct or indirect  sale or other  transfer,
including by merger or  consolidation,  of all or a substantial part of the
assets of Tenant or other  Transferor  to another  person or entity,  shall
constitute an  Assignment  for purposes of this Article 12. As used in this
Section 12.8,  the term  "Transferor"  shall also mean any entity which has
guaranteed Tenant's or other Transferor's  obligations under this Sublease,
and the  prohibitions  hereof shall be applicable to any direct or indirect
sales or  transfers of the stock,  partnership  interests or assets of said
guarantor  to  the  same  extent  as if  such  guarantor  were  the  Tenant
hereunder.

          12.9  Assumption of Obligations by Transferee.  Each  Transferee,
other than  Landlord,  shall  assume all  obligations  of Tenant under this
Sublease  and shall be and remain  liable for the payment of Rent,  and for
the performance of all of the terms,  covenants,  conditions and agreements
herein  contained on Tenant's part to be performed for the Term;  provided,
however,  that  without  limiting  the  obligations  of Tenant  under  this
Sublease  the  Transferee  shall be liable to Landlord for Rent only in the
amount set forth in the Assignment or Sublease unless  otherwise  agreed by
the parties  thereto.  No  Assignment  shall be binding on Landlord  unless
Tenant or other  Transferor  or  Transferee  shall  deliver  to  Landlord a
counterpart  of the  Assignment  and an instrument in recordable  form that
contains  a covenant  or  assumption  by such  Transferee  satisfactory  in
substance and form to Landlord and consistent with the requirements of this
Section 12.9, but the failure or refusal of such Transferee to execute such
instrument of  assumption  shall not release or discharge  such  Transferee
from its  liability as set forth above.  Tenant or other  Transferor  shall
reimburse  Landlord on demand for any reasonable costs that may be incurred
by  Landlord  in  connection  with any  proposed  Assignment  or  Sublease,
including without  limitation the costs of making  investigations as to the
acceptability  of  the  proposed  Transferee  and  reasonable  legal  costs
incurred  in  connection  with  the  granting  of  any  requested  consent.
Notwithstanding  the foregoing,  Tenant shall not be required to pay any of
the foregoing costs in connection with the granting of a requested  consent
which exceed seven  hundred  fifty  dollars  ($750.00).  If Landlord  shall
exercise any of its options under Section 12.3 (a) or (c), Transferor shall
indemnify,  defend and hold harmless Landlord and Ground Lessor against and
from any and all  loss,  liability,  damage,  cost and  expense  (including
without limitation reasonable attorneys' fees and disbursements)  resulting
from  any  claims  that  may be  made  against  Landlord  by  the  proposed
Transferee  or by  any  party  engaged  or  retained  by  Tenant  or  other
Transferor  or the  proposed  Transferee  in  connection  with any proposed
Assignment  or  Sublease,  including  without  limitation  any real  estate
brokers, agents or sales personnel.

          12.10 Approval by Ground Lessor.  The parties hereby  acknowledge
that any  Assignment  or Sublease  of the  Premises  must be  approved  and
consented to by the Ground  Lessor.  Landlord shall not be liable to Tenant
for Ground Lessor's failure to approve any such Assignment or Sublease.

     13.  Destruction.

          13.1 Restoration. If a substantial portion of the Building or the
other Improvements on the Premises shall be damaged or destroyed during the
Term of this Sublease,  the Tenant shall:  immediately  notify the Landlord
and the Ground  Lessor and may elect to promptly  commence and complete the
restoration  of the Building  and other  Improvements  (the  "Restoration")
within  eighteen (18) months after such damage occurs at Tenant's sole cost
and expense (even if such cost and expense  exceeds the amount of insurance
proceeds  that is  available  therefor) as nearly as possible to the value,
condition and character of the Improvements  immediately before such damage
or destruction,  all in accordance with Plans and  Specifications  therefor
which  have  been  approved  by  Landlord,  Ground  Lessor  and  any  other
applicable  parties.  Tenant shall complete the Restoration of the Premises
in  accordance  with  the  requirements  set  forth  in  Article  7 of this
Sublease.  If the  Restoration  is not completed  within said eighteen (18)
month  period,  Landlord,  in  addition  to all other  rights and  remedies
available at law or in equity shall be entitled to terminate  this Sublease
upon fifteen (15) days written notice to Tenant. In the event of any damage
or  destruction  of the Premises,  this Sublease shall remain in full force
and effect and rent shall not abate during this period. Notwithstanding the
foregoing,  in the event a substantial portion of the Building is destroyed
or damaged  during the Term,  Tenant shall not be obligated to complete the
Restoration  and shall notify  Landlord of its election not to complete the
Restoration  within  forty-five  (45)  days  after  the date the  damage or
destruction  has  occurred.  In the event Tenant elects not to complete the
Restoration or fails to make such election  within the forty-five  (45) day
period, Landlord shall be entitled to terminate this Lease upon thirty (30)
days  written  notice to Tenant and  Tenant  shall  have  thirty  (30) days
thereafter  to remove the  remaining  structure,  including  all debris and
rubbish,  so as to surrender the Premises to Landlord in the same condition
as on the date hereof.

          13.2  Insurance  Proceeds.  All insurance  proceeds  payable as a
result of such casualty  under  policies of insurance  against the same and
received by Tenant shall be deposited with an escrow agent mutually  agreed
upon by both parties (the "Depository") and shall be applied as follows:

                    (a) in the event that Tenant elects not to complete the
          Restoration or fails to make such election as provided above, the
          insurance proceeds shall be applied by the Depository as follows:

                         (i) First, to be paid to Tenant for removal of the
          remaining  structure,  including all debris and rubbish, so as to
          restore the Premises to the same condition as of the Commencement
          Date hereof;

                         (ii)  Second,  to be paid to Tenant to satisfy any
          indebtedness  incurred  by Tenant  solely  for the  construction,
          replacement or repair of the Building and other  Improvements  on
          the Premises;

                         (iii)  Third,  to be paid to Tenant for the amount
          expended by Tenant in  connection  with the  construction  of the
          ramp and the hook-up and related costs for  electrical  and water
          utilities on the Premises; and

                         (iv) Fourth, the balance, if any, of such proceeds
          shall be divided  between  Tenant and the Ground Lessor in such a
          way that Ground Lessor  receives the amount equal to such balance
          multiplied  by the ratio of which the  numerator is the number of
          months that Tenant has subleased  the Premises  hereunder and the
          denominator  is 408,  which is the total  number of months of the
          maximum term under this  Sublease,  as  determined  by the sum of
          months in the Initial Term and all five (5) Extensions Terms, and
          the Tenant receives the remainder, if any, of such balance.

                    (b) in the event that the Tenant elects to complete the
          Restoration,  the  insurance  proceeds  shall be  applied  by the
          Depository to the Tenant or as the Tenant may direct from time to
          time  as the  Restoration  progresses,  to pay or  reimburse  the
          Tenant for the cost of the  Restoration,  upon  Tenant's  written
          request accompanied by evidence satisfactory to the Landlord that
          an amount  equaling the amount  requested is then due and payable
          or has been paid,  and is properly a part of such cost,  and that
          the net insurance proceeds not yet advanced will be sufficient to
          complete the Restoration.  Before such construction commences and
          at any time thereafter  upon notice to it from the Landlord,  the
          Tenant  shall  deposit  with  the  Depository  such  sums  as are
          required  to  complete  the  Restoration.  Upon  receipt  by  the
          Landlord and Ground Lessor of evidence  satisfactory to them that
          such  Restoration has been completed and the cost thereof paid in
          full,  and that no mechanics',  materialmen'  or similar lien for
          labor or materials supplied in connection therewith may attach to
          the Premises, the balance, if any, of such proceeds shall be paid
          to Tenant or as it may direct.

          13.3 Application of Insurance Proceeds Upon Termination. Anything
contained   in  the   provisions   of  this   Sublease   to  the   contrary
notwithstanding, if the Tenant elects to commence Restoration under Section
13.1,  then upon the  expiration  or earlier  termination  of this Sublease
before  such  Restoration  is  completed  free and clear of any liens,  any
insurance proceeds not theretofore  applied to the cost of such Restoration
shall be paid directly to Landlord and Landlord shall utilize such proceeds
to  complete,  or cause to be  completed,  the  Restoration  to the  extent
possible  with the insurance  proceeds;  provided,  however,  that Landlord
shall not be required to pay for any restoration  work beyond the amount of
insurance proceeds that is available therefor, or, if Landlord elects, such
proceeds  shall be paid to the Ground Lessor and the Landlord shall have no
obligation to complete the Restoration.

          13.4 Waiver of Subrogation. Landlord and Tenant shall each obtain
and  maintain,  throughout  the Term,  in any casualty  insurance  policies
carried by such party covering any part of the Real Property, the Premises,
or the  contents  therein,  including  Tenant's  Property,  a waiver of all
rights of subrogation which the insurer of one party might have against the
other party,  which  waiver  shall be effective so long as a  corresponding
waiver  is  carried  by  the  other  party  in  its  policies.  In  further
implementation  of  the  foregoing,   each  party  hereby  waives  (a)  any
obligation on the part of the other party to make repairs  necessitated  or
occasioned  by fire or other  casualty  that is an insured  risk under such
policies,  and (b) any right of recovery against the other party, any other
permitted occupant of the Premises,  and any of their servants,  employees,
agents or  contractors,  for any loss  occasioned by fire or other casualty
that is an insured risk under such policies.  If such waiver of subrogation
can be obtained  under any such policy of insurance only upon payment of an
additional  premium and the party benefiting from such waiver shall not pay
such  additional  premium on demand,  or if such waiver  cannot be obtained
upon other conditions  acceptable to the party benefiting from such waiver,
then the party  benefiting  from such waiver shall be deemed to have agreed
that  the  other  party  shall  be  released  from  all  of  its  foregoing
obligations  and  waivers  under this  Section  13.4.  Except to the extent
expressly provided in this Section 13.4, nothing contained in this Sublease
shall  relieve  Tenant of any  liability  to Landlord  or to its  insurance
carriers  which Tenant may have under law or under the  provisions  of this
Sublease in  connection  with any damage to the Premises or the Building by
fire or other casualty.

     14.  Eminent Domain.

          14.1  Taking.  As used  herein,  the term  "Taking"  shall mean a
permanent or temporary  condemnation or taking of all or any portion of the
Premises or the  Building,  in any manner for public or  quasi-public  use,
including  but not  limited  to a  conveyance  or  assignment  in lieu of a
condemnation or taking. Except as otherwise provided in Section 14.6:

                    (a)  Entire  Premises.  If a Taking  covers  the entire
          Premises,  this Sublease shall automatically  terminate as of the
          earlier  of the  date of the  vesting  of  title  or the  date of
          dispossession of Tenant as a result of such Taking and the Annual
          Base Rent,  any  Additional  Rent and all other sums and  charges
          required to be paid by the Tenant  hereunder shall be apportioned
          and paid to the date of termination.

                    (b) Part of Premises. If a Taking covers only a part of
          the Premises,  this Sublease shall automatically  terminate as to
          the  portion of the  Premises  so taken as of the  earlier of the
          date of the  vesting  of title or the  date of  dispossession  of
          Tenant as a result of such condemnation or Taking.

                    (c) Substantial  Part of Premises.  If a portion of the
          Premises  is  taken  so  as  to  render  the  remaining   portion
          untenantable  and  unusable  by  Tenant,  this  Sublease  may  be
          terminated by Tenant as of the earlier of the date of the vesting
          of title or the date of  dispossession  of  Tenant as a result of
          such Taking, by written notice to Landlord within sixty (60) days
          following  notice to Tenant of the date on which said  vesting or
          dispossession  will  occur;  and if  Tenant  fails  to give  such
          written notice to Landlord  within said 60-day  period,  Tenant's
          right to so terminate  this Sublease shall be deemed to have been
          waived by Tenant.  Upon  termination,  the Annual Base Rent,  any
          Additional  Rent and all other sums and  charges  required  to be
          paid by the Tenant hereunder shall be apportioned and paid to the
          date of termination.

          14.2 Restoration.  If a Taking occurs and it covers less than the
entire  Premises and less than a  substantial  part of the Premises  (under
which  circumstances  the Tenant would not have a right to  terminate  this
Sublease) then:

                    (a) this  Sublease  shall  continue  in full  force and
          effect;

                    (b) the Tenant shall  promptly  give written  notice to
          Landlord  whether  Tenant elects to complete  Restoration  of the
          Premises in accordance with the terms of this Article 14;

                    (c)  whether  or  not  the  condemnation  proceeds  are
          available or adequate for such  purposes  and  regardless  of the
          cost of  Restoration,  the Tenant may elect,  promptly  after the
          date of Taking,  to  commence  and  complete  Restoration  of the
          Premises with reasonable  diligence at the Tenant's  expense,  as
          nearly  as  possible  to  its  value,   condition  and  character
          immediately  before such Taking, all in accordance with Plans and
          Specifications therefor which shall have been approved in writing
          by the  Landlord  and Ground  Lessor and in  accordance  with the
          requirements set forth in Article 7 of this Sublease; and

                    (d) in the event the  Tenant  elects  to  complete  the
          Restoration, the condemnation proceeds shall be paid to an escrow
          agent mutually  approved by the parties (the  "Depository"),  and
          shall be paid by the Depository in the following order:

                         (i) First,  the  Depository  shall  reimburse  the
          Tenant for the cost of restoring the Premises,  upon the Tenant's
          written  request  accompanied  by  evidence  satisfactory  to the
          Landlord that an amount  equalling  the amount  requested is then
          due and payable or has been paid,  and is properly a part of such
          cost, and that the condemnation proceeds not yet advanced will be
          sufficient to complete such Restoration. Before such construction
          commences and at any time  thereafter  upon notice to it from the
          Landlord or the Ground Lessor,  the Tenant shall deposit with the
          Depository  such sums as are  required (in addition to any amount
          then held by the  Depository  for such  purpose) to complete such
          Restoration; and

                         (ii)  Second,   the   Depository   shall  pay  the
          remaining  condemnation  proceeds, if any, to the Tenant or as it
          may direct.

                    (e)  In  the  event  Tenant   elects  not  to  commence
          Restoration or fails to make such election within sixty (60) days
          of the  Taking,  Landlord  shall be entitled  to  terminate  this
          Sublease  upon thirty (30) days written  notice to Tenant and the
          condemnation proceeds shall be applied as follows:

                         (i) First, to be paid to Tenant for removal of the
          remaining  structure,  including all debris and rubbish, so as to
          restore the Premises to the same condition as of the Commencement
          Date hereof;

                         (ii)  Second,  to be paid to Tenant to satisfy any
          indebtedness  incurred  by Tenant  solely  for the  construction,
          replacement or repair of the Building and other  Improvements  on
          the Premises;

                         (iii)  Third,  to be paid to Tenant for the amount
          expended by Tenant in  connection  with the  construction  of the
          ramp and the hook-up and related costs for  electrical  and water
          utilities on the Premises; and

                         (iv) Fourth, the balance, if any, of such proceeds
          shall be divided  between  Tenant and the Ground Lessor in such a
          way that Ground Lessor  receives the amount equal to such balance
          multiplied  by the ratio of which the  numerator is the number of
          months that Tenant has subleased  the Premises  hereunder and the
          denominator  is 408,  which is the total  number of months of the
          maximum term under this  Sublease,  as  determined  by the sum of
          months in the Initial Term and all five (5) Extensions Terms, and
          the Tenant receives the remainder, if any, of such balance.

          14.3 Application of Proceeds Upon Termination. Anything contained
in the provisions of this Sublease to the contrary notwithstanding,  if the
Tenant elects to commence Restoration under Section 14.2(b),  then upon the
expiration or earlier  termination of this Sublease before such Restoration
is  completed  free and clear of any such  liens,  any of the  condemnation
proceeds not theretofore  applied to the cost of such Restoration  shall be
paid to the Landlord and Landlord  shall utilize such proceeds to complete,
or cause to be  completed,  the  Restoration  to the extent  possible  with
condemnation  proceeds;  provided,  however, that the Landlord shall not be
required to pay for any restoration  work beyond the amount of condemnation
proceeds that is available therefor,  or, if Landlord elects, such proceeds
shall  be  paid  to the  Ground  Lessor  and  the  Landlord  shall  have no
obligation to complete the Restoration.

          14.4 Condemnation  Award. In the event of a Taking,  Landlord and
Tenant  shall each be entitled  to seek  separate  condemnation  awards for
their respective interests hereunder.

          14.5  Rental  Abatement.  In the event of a Taking  that does not
result in a termination  of this Sublease as to the entire  Premises,  then
except as  otherwise  provided  in  Section  14.4 the Rent  shall  abate in
proportion to the portion of the Premises covered by such Taking,  but only
to the extent that such Taking  materially  interferes  with the conduct of
Tenant's business on the remaining portion of the Premises.

          14.6 Temporary  Taking.  Notwithstanding  any other  provision of
this Article 14 and subject to the provisions of Article 27 hereafter, if a
Taking  occurs  with  respect to all or any portion of the  Premises  for a
limited period of time,  but in no event more than thirty (30)  consecutive
days  during  the  Term  of  this  Sublease,  this  Sublease  shall  remain
unaffected  thereby and Tenant shall continue to pay in full all Rent. Rent
shall abate if the temporary  Taking occurs for longer than the thirty (30)
day period. In the event of any such temporary Taking,  Landlord and Tenant
shall be entitled to seek separate  condemnation awards for their interests
in the Premises hereunder.

     15.  Expansion Option.

          15.1  Option.   Tenant  shall  have  the  exclusive  option  (the
"Expansion  Option")  to  sublease  approximately  45,000  square  feet  of
additional  improved apron space,  designated as the "Option Lease Area" on
Exhibit B attached hereto (the "Option  Premises"),  which Expansion Option
shall commence on the  Commencement  Date of this Sublease and shall expire
on the  third  (3rd)  year  anniversary  of the  Commencement  Date of this
Sublease (the "Option Period").

          15.2  Exercise.  Provided  Tenant is not in  default  under  this
Sublease or the Fuel Sales  Agreement,  Tenant may exercise  the  Expansion
Option by giving  notice of such  exercise to Landlord six (6) months prior
to the date Tenant desires to occupy the Option  Premises,  but in no event
later than the date which is six (6) months prior to the  expiration of the
Option Period. If Tenant fails to timely exercise the Expansion Option, the
Expansion Option shall be null and void and of no further force and effect.

          15.3 Covenant to Build  Expansion  Facility.  In the event Tenant
exercises  the  Expansion  Option,  Tenant  shall be  obligated to build an
expansion facility (the "Expansion  Facility") for the purpose set forth in
Section 5.1 of this Sublease. Such Expansion Facility shall be completed in
accordance  with Article 7 of this  Sublease.  In the event Tenant fails to
complete  the  Expansion  Facility  within two (2) years after the date the
Expansion  Option is exercised,  Landlord shall have the right, in addition
to all other rights and remedies,  to terminate  this  Sublease;  provided,
however,  that such two (2) year period may be extended  as  necessary  for
delays due to labor disputes,  Acts of God or the public enemy, casualty or
other  conditions  or causes  beyond  Tenant's  control,  so long as Tenant
notifies  Landlord  of the delay and the reasons for such delay and so long
as Tenant thereafter  recommences  construction as soon as possible. In the
event that the  Landlord  terminates  this  Sublease,  the  Landlord  shall
complete the  Expansion  Facility  only to the extent that the Tenant,  the
Tenant's  lenders,  or the payment bond and the  performance  bond that the
Tenant  has  obtained  supply  funds  for the  payment  thereof;  provided,
however,  that the Landlord shall not be required to pay for any completion
work with its own funds.

          15.4  Rental  and  Terms.  In  the  event  Tenant  exercises  the
Expansion  Option,  the Option  Premises  shall be deemed  included  in the
Premises,  and Tenant will lease the Option  Premises on the same terms and
conditions as this Sublease,  including,  but not limited to the prevailing
Base  Rent (on a  per-square-foot  basis)  then in  effect  at the time the
Expansion Option is exercised. The Base Rent then in effect hereunder shall
thereupon  be  increased  accordingly,  and any future  Rental  Adjustments
relating  to the  Premises  shall  be  based  on the  area of the  Premises
including the Option Premises.

          15.5  "As Is".  In the  event  Tenant  exercises  this  Expansion
Option,  Landlord shall demise the Option Premises to Tenant "as is" in the
same  physical  state and  condition  existing as of the date the Expansion
Option is exercised.

          15.6 Amendment. If Tenant sends to Landlord the Expansion Notice,
then  Landlord  should  prepare an  Amendment  to this  Sublease to reflect
changes  in the  size  of the  Premises,  Annual  Base  rent  and  Tenant's
Percentage  Share,  all of which shall be increased by each rentable square
foot by which the  Premises  are  increased  by the  addition of the Option
Premises,  which  Amendment  shall be subject to the approval of the Ground
Lessor. Tenant shall have twenty (20) days from the date of receipt of such
Amendment to enter into the same.

     16.  Common Areas.

          16.1  Landlord  Common  Area.  Tenant,  its  employees,   agents,
servants, licensees, subtenants,  contractors,  customers or invitees shall
have the right to use the area  designated on Exhibit B attached  hereto as
the  "Landlord  Common  Area" on a  non-exclusive  basis for the purpose of
taxiing planes,  vehicles and other equipment and machinery to and from the
Premises so long as such use does not interfere with  Landlord's use of the
Landlord  Common  Area.  Tenant  shall not be permitted to park any planes,
vehicles and other machinery or equipment on the Landlord Common Area.

          16.2 Tenant Common Area. Tenant, its employees, agents, servants,
licensees,  subtenants,  contractors,  customers or invitees shall have the
right to use the area  designated  on  Exhibit  B  attached  hereto  as the
"Tenant  Common Area" on a  non-exclusive  basis for the purpose of taxiing
planes,  vehicles  and  other  equipment  and  machinery  to and  from  the
Premises,  and the  parking  of planes,  vehicles  and other  machinery  or
equipment;  provided  that Tenant's use of the Tenant Common Area shall not
interfere with the  non-exclusive use of the Tenant Common Area by Landlord
for taxiing planes, vehicles and other machinery.

          16.3 Tenant Option Common Area. In the event Tenant exercises the
Expansion  Option,  Landlord  and  Tenant  agree  that the  portion  of the
Landlord  Common Area  designated on Exhibit B as the "Tenant Option Common
Area" shall  thereafter  be included in the Tenant Common Area and excluded
from the Landlord Common Area, and Tenant, its employees, agents, servants,
licensees,  subtenants,  contractors,  customers or invitees shall have the
right to use the Tenant  Option Common Area on the same basis as the Tenant
Common Area.  (The Landlord  Common Area, the Tenant Common Area and Tenant
Option Common Area are hereinafter  collectively referred to as the "Common
Areas".)

          16.4  Taxiways.  Landlord  and  Tenant  shall  have the  right to
utilize the  taxiways  (the  "Taxiways")  identified  in Exhibit B. Neither
Tenant nor Landlord are permitted to park  vehicles,  planes,  machinery or
other equipment on the Taxiways.

          16.5 Rules and  Regulations.  Landlord may promulgate  reasonable
rules and  regulations  relating to the use of the Common Areas by Landlord
and Tenant.

          16.6  Additional  Common Area Rent.  Landlord  and Tenant  hereby
acknowledge  that the  Common  Areas are  located  on a portion of the Land
designated as improved  apron space by the Ground  Lessor,  and Landlord is
obligated to pay Ground Lessor rental for such improved apron space ("Apron
Space Rental")  commencing  September 1, 1998.  Tenant shall be responsible
for its pro rata share of Apron  Space  Rental as and when such Apron Space
Rental is payable by  Landlord.  Tenant's  share of such Apron Space Rental
shall be Additional Rent  hereunder,  and shall be payable on or before the
date such Apron Space Rental is payable to Ground Lessor by Landlord.

     17.  Default.

          17.1 Events of Default by Tenant.  Any vacation or abandonment of
the Premises for a continuous period in excess of five (5) business days or
any  failure to pay any Rent as and when due,  or any failure to perform or
comply   strictly   with  any   material   covenant  or   condition  of  or
representation made under this Sublease (including any Exhibits hereto), or
any  default  under  the  terms of the Fuel  Sales  Agreement  of even date
hereof,  shall  constitute a default  hereunder  by Tenant,  subject in the
specific  instances set forth below to the  expiration  of the  appropriate
grace period hereinafter  provided.  Tenant shall have a period of five (5)
days from the date of receipt of written notice from Landlord  within which
to cure any default in the payment of Rent.  Tenant  shall have a period of
fifteen (15) days from the date of receipt of written  notice from Landlord
within  which to cure any other  default  under  this  Sublease;  provided,
however,  that with  respect to any default  other than the payment of Rent
that cannot reasonably be cured within fifteen (15) days, the default shall
not be deemed  uncured  if Tenant  commences  to cure such  default  within
fifteen  (15)  days from  Landlord's  notice  and  continues  to  prosecute
diligently the curing thereof to completion within a reasonable time.

          17.2 Rights and Remedies of Landlord.  Upon the  occurrence  of a
default by Tenant which is not cured by Tenant within the applicable  grace
period specified in Section 17.1,  Landlord shall have the following rights
and  remedies  in addition to all other  rights or  remedies  available  to
Landlord at law or in equity:

                    (a) The right to terminate Tenant's right to possession
          of the  Premises and to recover the worth at the time of award of
          the amount by which the unpaid  Rent for the  balance of the Term
          after the time of award  exceeds the fair and  reasonable  rental
          value of the Premises for the same period.  In the computation of
          such  amount  the  difference  between  any  installment  of Rent
          becoming due hereunder and after the date of  termination of this
          Sublease and the reasonable  rental value of the Premises for the
          period for which such installment was payable shall be discounted
          to its  present  value  as of the  date  of  termination  of this
          Sublease at the rate of six percent (6%) per annum.

                    (b) The right to continue  this  Sublease in effect and
          to enforce all of its rights and  remedies  under this  Sublease,
          including  the right to recover  Rent as it becomes  due,  for so
          long as Landlord does not terminate Tenant's right to possession.
          Acts  of  maintenance  or  preservation,  efforts  to  relet  the
          Premises  or  the  appointment  of  a  receiver  upon  Landlord's
          initiative to protect its interest  under this Sublease shall not
          constitute a  termination  of Tenant's  right to  possession.  If
          Landlord   exercises  its  rights  under  this   subsection  (b),
          Landlord,  as attorney-in-fact  for Tenant, may from time to time
          sublet the  Premises  or any part  thereof for such term or terms
          (which may extend beyond the Term) and at such rent and upon such
          other terms as Landlord in its sole and absolute  discretion  may
          deem advisable, with the right to make alterations and repairs to
          the  Premises.  Upon each such  subletting,  (i) Tenant  shall be
          immediately  liable for  payment to  Landlord  of, in addition to
          Rent  due  hereunder,  the  cost  of  such  subletting  and  such
          alterations and repairs  incurred by Landlord and the amount,  if
          any,  by which the Rent  owing  hereunder  for the period of such
          subletting  (to the extent  such period does not exceed the Term)
          exceeds the amount to be paid as Rent for the  Premises  for such
          period  pursuant  to such  subletting,  or (ii) at the  option of
          Landlord,  rents received from such subletting  shall be applied,
          first,  to  payment  of any  indebtedness  other  than  Rent  due
          hereunder from Tenant to Landlord;  second, to the payment of any
          costs of such  subletting  and of such  alterations  and repairs;
          third,  to  payment  of Rent due and  unpaid  hereunder;  and the
          residue, if any, shall be held by Landlord and applied in payment
          of future Rent as the same becomes due  hereunder.  If Tenant has
          been credited  with any rent to be received from such  subletting
          under  clause  (i) and such rent  shall not be  promptly  paid to
          Landlord by the  subtenant(s),  or if such rentals  received from
          such subletting  under clause (ii) during any month are less than
          those required to be paid during that month by Tenant  hereunder,
          Tenant shall pay any such deficiency to Landlord. Such deficiency
          shall  be  calculated  and  paid  monthly  within  five  (5) days
          following  written  notice from  Landlord.  For all  purposes set
          forth in this Section 17.2(b) and in Section 17.2(d), Landlord is
          hereby irrevocably  appointed  attorney-in-fact  for Tenant, with
          power of substitution. No taking of possession of the Premises by
          Landlord,  as attorney-in-fact  for Tenant, shall be construed as
          an election on its part to  terminate  this  Sublease or Tenant's
          right to possession  unless a written notice of such intention is
          given to Tenant.  No action  taken by  Landlord  pursuant to this
          paragraph shall be deemed a waiver of any default by Tenant,  and
          notwithstanding any such subletting without termination, Landlord
          may at any time  thereafter  elect to terminate this Sublease for
          such previous default.  Notwithstanding  the foregoing,  Landlord
          shall use reasonable efforts to mitigate the damages hereunder.

                    (c) The right to terminate this Sublease and dispossess
          Tenant by giving notice to Tenant in accordance  with  applicable
          Texas law.

                    (d)  The  right  and  power,  as  attorney-in-fact  for
          Tenant,  to enter the Premises and remove  therefrom  all persons
          and  property,  to store such  property in a public  warehouse or
          elsewhere  at the cost of and for the  account of Tenant,  and to
          sell such property and apply the proceeds  therefrom  pursuant to
          applicable Texas law.

                    (e) The right to have a receiver  appointed for Tenant,
          upon application by Landlord,  to take possession of the Premises
          and to  apply  any  rental  collected  from the  Premises  and to
          exercise  all other  rights and  remedies  granted to Landlord as
          attorney-in-fact  for  Tenant  pursuant  to Section  17.2(b)  and
          Section 17.2(d).

          17.3 Events of Default by Landlord.  In the event  Landlord fails
to perform any covenant or condition  or breaches any  representation  made
under this Sublease (including any Exhibits thereto), this shall constitute
an event of default by  Landlord.  Landlord  shall have a period of fifteen
(15) days from receipt of written  notice from Tenant  within which to cure
any default under this Sublease;  provided,  however,  that with respect to
any default  which  cannot be cured within  fifteen (15) days,  the default
shall not be deemed to be uncured  so long as  Landlord  commences  to cure
such default within fifteen (15) days from Tenant's notice and continues to
prosecute  diligently the curing thereof to completion  within a reasonable
time.  In the event of a default by  Landlord,  Tenant shall be entitled to
all rights and remedies at equity or at law.

          17.4 Indemnities. Termination of this Sublease under this Article
17 and  exercise of any  remedies of Landlord as provided  herein shall not
affect or terminate  the right of Landlord and Ground Lessor to enforce any
and all  indemnities  given  Landlord or Ground  Lessor by Tenant under the
terms of this Sublease,  which indemnities shall survive any termination of
this Sublease.

     18.  Insolvency or Bankruptcy.

          The  appointment  of a  receiver  to  take  possession  of all or
substantially  all of the assets of Tenant,  or an assignment by Tenant for
the benefit of creditors, or the commencement of a case or proceeding by or
against  Tenant or any other  action  taken or suffered by Tenant under any
insolvency, bankruptcy,  reorganization,  moratorium or other debtor relief
act or statute, whether now existing or hereafter amended or enacted, shall
constitute a breach of this  Sublease by Tenant.  Upon the happening of any
such event,  this Sublease shall  automatically  terminate  without further
notice of termination  from Landlord to Tenant,  provided that Landlord may
enforce any of its remedies  under  Section  17.2,  except  subsection  (b)
thereof, and provided further that neither such termination nor exercise of
remedies shall affect or terminate the right of Landlord to enforce any and
all indemnities  given Landlord by Tenant under the terms of this Sublease.
In no event shall this  Sublease be assigned or  assignable by operation of
law  or by  virtue  of or  in  any  voluntary  or  involuntary  bankruptcy,
reorganization  or insolvency  case or  proceeding or otherwise,  and in no
event shall this Sublease or any rights or privileges hereunder be an asset
of Tenant under any bankruptcy, reorganization,  insolvency or other debtor
relief proceeding.

     19.  Fees and Expenses; Indemnity; Insurance.

          19.1  Fees  and   Expenses.   If  Tenant  shall  default  in  the
performance of any of its obligations under this Sublease, Landlord, at any
time  thereafter  and  with  reasonable  notice  (unless  in the case of an
emergency),  may remedy such default for  Tenant's  account and at Tenant's
expense,  without thereby waiving such default or any rights or remedies of
Landlord on account of such default. Except as specifically provided to the
contrary in this  Sublease,  Tenant shall pay to Landlord,  within five (5)
days after delivery by Landlord to Tenant of bills or statements  therefor:
(a) sums equal to all expenditures made and monetary  obligations  incurred
by  Landlord   including,   without   limitation,   expenditures  made  and
obligations  incurred for  reasonable  counsel fees and  disbursements,  in
connection with any remedying by Landlord for Tenant's  account pursuant to
the immediately  preceding sentence;  (b) sums equal to all losses,  costs,
liabilities,  damages and expenses  referred to in Section  19.2;  (c) sums
equal  to all  expenditures  made  and  monetary  obligations  incurred  by
Landlord, including, without limitation,  expenditures made and obligations
incurred for reasonable  counsel fees and  disbursements,  in collecting or
attempting to collect any Rent or in enforcing or attempting to enforce any
rights of  Landlord  under  this  Sublease  or  pursuant  to law.  Tenant's
obligations  under this Section 19.1 shall survive the  expiration or other
termination of this Sublease.

          19.2  Indemnification.  Tenant  agrees to indemnify  Landlord and
Ground Lessor against and save Landlord and Ground Lessor harmless from any
and all loss,  cost,  liability,  damage  and  expense  including,  without
limitation,  any reasonable  counsel fees incurred in attempting to collect
any Rent or in enforcing or attempting to enforce any rights of Landlord or
Ground Lessor under this Sublease or pursuant to law. Tenant's  obligations
under this Section 19.2 shall survive the  expiration or other  termination
of this Sublease.

          19.3  Additional  Indemnification.  Tenant  agrees  to  indemnify
Landlord and Ground  Lessor  against and save  Landlord  and Ground  Lessor
harmless  from  any and all  loss,  cost,  liability,  damage  and  expense
including, without limitation, penalties, fines and reasonable counsel fees
and  disbursements,  incurred in connection  with or arising from any cause
whatsoever in, on or about the Premises,  including,  without  limiting the
generality of the foregoing (a) any default by Tenant in the  observance or
performance  of any of the terms,  covenants or conditions of this Sublease
or the Ground Lease on Tenant's  part to be observed or  performed,  or (b)
the use or  occupancy  or manner of use or  occupancy  of the  Premises  by
Tenant or any person or entity claiming through or under Tenant, or (c) the
condition  of the Premises or any  occurrence  or happening on the Premises
from any cause  whatsoever,  or (d) any acts,  omissions or  negligence  of
Tenant or any person or entity claiming through or under Tenant,  or of the
contractors,  agents, servants, employees, customers, visitors or licensees
of Tenant or any such person or entity,  in, on or about the  Premises,  or
all or any part of the Real Property, either prior to, during, or after the
expiration of, the Term including,  without limitation, any acts, omissions
or negligence in the making or  performing  of any Tenant  Changes.  Tenant
further  agrees to indemnify  and save  harmless  Landlord  and  Landlord's
agents,  and the  lessor or lessors  under the  Ground  Lease and under all
other ground or underlying leases, from and against any and all loss, cost,
liability,  damage and expense including,  without  limitation,  reasonable
counsel fees and disbursements, incurred in connection with or arising from
any claims by reason of injury to persons or damage to property  occasioned
by any default,  use, occupancy,  condition,  occurrence,  happening,  act,
omission or negligence referred to in the preceding sentence.  In the event
any action or proceeding is brought  against  Landlord or Ground Lessor for
any claim against which Tenant is obligated to indemnify Landlord or Ground
Lessor hereunder, Tenant upon notice from Landlord shall defend such action
or proceeding  at Tenant's  sole expense by counsel  selected by Tenant and
reasonably  approved by Landlord.  Tenant's  obligations under this Section
19.3 shall survive the expiration or other termination of this Sublease.

          19.4 Insurance.  Tenant shall procure at its cost and expense and
keep  in  effect  during  the  Term  (a)  comprehensive  general  liability
insurance,  including without limitation contractual liability and specific
coverage  of risks  arising  out of any  activities  of Tenant  pursuant to
Article 7, with a minimum  combined  single limit of liability of Three (3)
million  dollars  ($3,000,000.00),  which limit of  liability  Landlord may
increase  from time to time in its  reasonable  discretion  to a level then
generally  maintained  by prudent  Fixed Base  Operations  ("FBOs") for the
coverage of  comparable  risks by giving  written  notice to Tenant of such
adjustment in the required  limit of liability of Tenant's  insurance,  and
which  insurance  shall  specifically  include  all  liability  (subject to
standard policy exclusions)  assumed hereunder by Tenant (provided that the
amount of such  insurance  shall not be construed to limit the liability of
Tenant  hereunder);  (b) insurance  against  damage or destruction by fire,
lightning  and other  risks  from  time to time  included  under  generally
available extended coverage endorsements in an amount adequate to cover the
cost of  replacement  of all  Improvements,  Tenant  Changes  and  Tenant's
Property and within the  Premises;  (c)  workmen's  compensation  insurance
having such limits, and under such terms and conditions, as are required by
applicable  law;  and (d)  Builders  Risk  insurance  during  the period of
construction,  in an  amount  determined  by  Landlord  in  its  reasonable
discretion. To the extent that either of Landlord or Ground Lessor, or both
of them, have an insurable  interest  hereunder,  such insurance shall name
Landlord and Ground Lessor as an additional insured,  shall provide that it
is primary  insurance,  and not excess over or contributory  with any other
valid,  existing  and  applicable  insurance  in force  for or on behalf of
Landlord,  and shall  provide that Landlord and Ground Lessor shall receive
thirty (30) days' written notice from the insurer prior to any cancellation
or change of coverage.  Tenant shall deliver  policies of such insurance or
certificates  thereof  to  Landlord  and  Ground  Lessor on or  before  the
Commencement  Date,  and  thereafter  at least  thirty (30) days before the
expiration dates of expiring policies;  and, in the event Tenant shall fail
to procure such  insurance,  or to deliver such  policies or  certificates,
Landlord may, at its option,  upon three (3) days prior  written  notice to
Tenant,  procure same for the account of Tenant, and the cost thereof shall
be paid to  Landlord  within  five (5) days after  delivery  to Tenant of a
statement therefor. Tenant's compliance with the provisions of this Section
19.4  shall in no way  limit  Tenant's  liability  under  any of the  other
provisions of this Article 19.

          19.5 Landlord Not Responsible.  Landlord shall not be responsible
for or liable to Tenant for any loss or damage that may be occasioned by or
through the acts or omissions of persons occupying or using any part of the
Real  Property,  or for any  loss or  damage  resulting  to  Tenant  or its
property from burst, damaged,  stopped or leaking water, gas, sewer, steam,
air or heat pipes or ducts or from any  electrical  equipment  accidents or
malfunctions,  or for any damage or loss of  property  within the  Premises
from any causes whatsoever, including theft.

     20.  Access to Premises; Security.

          20.1  Access  to  Premises.  Landlord  reserves  and at all times
during  the  Term  shall  have  the  right to  enter  the  Premises  at all
reasonable  times  upon  prior  notice  to  Tenant  (except  in the case of
emergencies)   to  inspect  same,  to  show  the  Premises  to  prospective
purchasers,  mortgagees and tenants, to post notices of non-responsibility,
and to alter,  improve  or  repair  the  Premises  and any  portion  of the
Building.  Landlord  may  for  any of the  above  purposes  erect,  use and
maintain scaffolding, pipes, conduits and other necessary structures in and
through the Premises where reasonably required by the character of the work
to be  performed,  the  business  of Tenant  shall not be  interfered  with
unreasonably.  For each of the aforesaid  purposes,  Landlord  shall at all
times have and retain a key with which to unlock all of the doors in,  upon
and about the Premises,  excluding  Tenant's  vaults and safes,  or special
security areas  (designated in advance in writing by Tenant),  and Landlord
shall  have  the  right to use any and all  means  that  Landlord  may deem
necessary  or proper to open said doors in an  emergency in order to obtain
entry to any  portion of the  Premises,  and any entry to the  Premises  or
portions  thereof  obtained by Landlord by any of said means, or otherwise,
shall not under any  circumstances  be construed or deemed to be a forcible
or unlawful  entry into,  or a detainer of, the  Premises,  or an eviction,
actual or constructive, of Tenant from the Premises or any portion thereof.
Landlord  shall have the right to enter and inspect  any  special  security
areas  referred to in the  immediately  preceding  sentence  upon notice to
Tenant,  provided that Tenant may require  Landlord to be  accompanied by a
representative of Tenant during such inspection.  Tenant shall be liable to
Landlord for all of Landlord's damages, including consequential damages, to
the  extent  Landlord  is  unable  to  protect  all or any part of the Real
Property  during an  emergency  because of  Landlord's  lack of access to a
special security area. Landlord  acknowledges that in gaining access to the
Premises it may be exposed to certain  confidential  information.  Landlord
and its agents and employees shall use reasonable  measures not to disclose
such confidences to third parties.

          20.2  Security.  Landlord  shall  have no  obligation  to furnish
guards,  watchmen,  patrols or similar security  personnel for the Building
and the Premises at any time during the Term,  and Tenant hereby  expressly
assumes (i) the  obligation  to furnish such  security  personnel,  at such
hours and at such stations,  as Tenant deems necessary or desirable for the
safety of Tenant's  employees  and  invitees,  and (ii) any and all risk of
injury,  damage or loss sustained to or by persons or property  arising out
of the absence of security  personnel  at the Building and the Premises and
abrogation  of any  responsibility  on the  part  of  Landlord  to  furnish
security  personnel  for the  Building  or the  Premises  pursuant  to this
Sublease.

     21.  Notices.

          Except as  otherwise  expressly  provided in this  Sublease,  any

or to such other address as either  Landlord or Tenant may designate as its
new address  for such  purpose by notice  given to the other in  accordance
with the provisions of this Section 21. Any such bill,  statement,  notice,
demand,  request  or other  communication  shall  be  deemed  to have  been
rendered  or given  upon the  earlier of receipt or five (5) days after the
date when it shall have been mailed as provided in this Section 21. If sent
by certified  mail, or upon the date personal  delivery is made,  provided,
however,  that any refusal to accept personal  delivery or delivery by mail
shall be deemed to constitute receipt thereof. If Tenant is notified of the
identity and address of any ground or underlying lessors of the Land or any
part thereof, or any mortgagees or deed of trust beneficiaries of Landlord,
at  Landlord's  request  Tenant  shall  give to such  ground or  underlying
lessors, or such mortgagees or beneficiaries,  as applicable, notice of any
default by Landlord under the terms of this Sublease, which notice shall be
in writing sent by certified  mail, and such ground or underlying  lessors,
or such  mortgagees  or  beneficiaries,  as  applicable,  shall  be given a
reasonable opportunity,  but shall have no obligation, to cure such default
prior to Tenant exercising any remedy available to it.

     22.  Mutual Waivers.

          22.1 No Waiver.  No failure  by either  party to insist  upon the
strict performance of any obligation of the other party under this Sublease
or to exercise any right,  power or remedy consequent upon a breach thereof
shall  constitute a waiver of any such breach or of such term,  covenant or
condition.  No acceptance of full or partial Rent during the continuance of
any such breach,  and no  acceptance  of the keys to or  possession  of the
Premises by any employee of Landlord prior to the  termination of the Term,
shall  constitute a waiver of any such breach or of such term,  covenant or
condition or operate as a surrender of this Sublease.  No payment by Tenant
or receipt by Landlord of a lesser  amount than the  aggregate  of all Rent
then due under this Sublease shall be deemed to be other than on account of
the first items of such Rent then accruing or becoming due, unless Landlord
elects  otherwise;  and no  endorsement  or  statement  on any check and no
letter or other writing  accompanying any check or other payment of Rent in
any such lesser  amount and no  acceptance  of any such check or other such
payment  by  Landlord  shall  constitute  an accord and  satisfaction,  and
Landlord may accept such check or payment  without  prejudice to Landlord's
right to recover  the  balance  of such Rent or to pursue  any other  legal
remedy.

          22.2 Written  Instrument.  Neither this  Sublease nor any term or
provision hereof may be changed,  waived,  discharged or terminated orally,
and no breach  thereof  shall be waived,  altered or modified,  except by a
written instrument signed by the party against which the enforcement of the
change,  waiver,  discharge or  termination  is sought,  and subject in any
event to the  provisions  of Section  11.1.  No waiver of any breach  shall
affect or alter  this  Sublease,  but each and  every  term,  covenant  and
condition  of this  Sublease  shall  continue in full force and effect with
respect  to any other then  existing  or  subsequent  breach  thereof.  The
consent of Landlord  given in any instance under the terms of this Sublease
shall  not  relieve  Tenant of any  obligation  to secure  the  consent  of
Landlord in any other or future instance under the terms of this Sublease.

     23.  Tenant's Certificates.

          Tenant  at any time and from  time to time upon not less than ten
(10) days'  prior  written  notice  from  Landlord  or Ground  Lessor  will
execute, acknowledge and deliver to Landlord and, at Landlord's request, to
any  prospective  purchaser  or any then current or  prospective  ground or
underlying  lessor  or  mortgagee  of any  part  of the  Real  Property,  a
certificate  of Tenant  stating:  (a) that Tenant has accepted the Premises
(or, if Tenant has not done so, that Tenant has not  accepted  the Premises
and specifying the reasons  therefor),  (b) the Commencement and Expiration
Dates of this  Sublease,  (c) that this Sublease is unmodified  and in full
force and effect  (or,  if there have been  modifications,  that same is in
full force and effect as  modified  and  stating  the  modifications),  (d)
whether or not there are then existing any defenses against the enforcement
of any of the  obligations  of Tenant  under  this  Sublease  (and,  if so,
specifying  same),  (e) whether or not there are then existing any defaults
by Landlord in the performance of its obligations under this Sublease (and,
if so,  specifying same), (f) the dates, if any, to which the Rent has been
paid, and (g) any other information,  including,  without  limitation,  any
public  financial   information  of  Tenant  or  its  parent  or  affiliate
corporations, that may reasonably be required by any of such persons. It is
intended that any such  certificate  of Tenant  delivered  pursuant to this
Section 23 may be relied upon by Landlord and any prospective  purchaser or
any then current or prospective ground or underlying lessor or mortgagee of
all or any part of the Real Property.

     24.  Guaranty.

          [INTENTIONALLY DELETED]

     25.  Authority.

          25.1  Authority  of Tenant.  Each of the persons  executing  this
Sublease on behalf of Tenant does hereby  covenant  and warrant that Tenant
is a duly  authorized and existing  Delaware  corporation,  Tenant has full
right and authority to enter into and perform this Sublease,  and that each
and all of the persons signing on behalf of Tenant are authorized to do so.
Upon  Landlord's  request,  Tenant shall  provide  Landlord  with  evidence
reasonably  satisfactory to Landlord confirming the foregoing covenants and
warranties.

          25.2  Authority of Landlord.  Each of the persons  executing this
Sublease on the part of  Landlord  does hereby  covenant  and warrant  that
Landlord is a duly authorized and existing Nevada corporation, Landlord has
full right and authority to enter into and perform this Sublease,  and that
each and all of the persons  behalf of Landlord  are  authorized  to do so.
Upon  Tenant's  request,   Landlord  shall  provide  Tenant  with  evidence
reasonably  satisfactory to Tenant  confirming the foregoing  covenants and
warranties.

     26.  Arbitration.

          Any dispute,  controversy or claim which this Sublease  expressly
requires or permits to be submitted to arbitration, or the determination of
the amount of any abatement of Rent provided for in this Sublease  which is
not agreed to by the parties  within a reasonable  time following the event
or condition giving rise to such abatement, shall be settled by arbitration
in the City of Dallas by three  arbitrators,  one of whom shall be selected
by Landlord,  one of whom shall be selected by Tenant and the other of whom
shall be selected by the mutual agreement of the arbitrators so selected by
Landlord and Tenant. Such arbitration shall be conducted in accordance with
the  Rules  of   Commercial   Arbitration   of  the  American   Arbitration
Association,  or its  successor.  The  arbitrators  shall  have no power to
modify any of the  provisions  of this Sublease and their  jurisdiction  is
limited accordingly.  The expenses of arbitration shall be borne equally by
the parties, provided that each party shall be responsible for the fees and
expenses of its own experts,  evidence and attorneys, and of the arbitrator
appointed  by  such  party.  The  decision  of  the  arbitrators  shall  be
conclusive, nonappealable and binding upon the parties hereto, and judgment
upon the award  rendered  by the  arbitrators  may be  entered in any court
having  jurisdiction  thereof.  It is understood and agreed by the Landlord
and  Tenant  that the  Ground  Lessor  shall not be  subject to or bound by
arbitration.

     27.  Termination of Sublease by Tenant.

          Tenant may terminate this Sublease and its obligations  hereunder
so long as Tenant is not in  default  in the  payment of any amount due the
Landlord,  by giving Landlord thirty (30) days written notice upon or after
the happening of any one of the following events:

                    (a) The issuance by any court of competent jurisdiction
          of any injunction preventing or restraining the use of Love Field
          Airport for the purposes  described herein, the same to remain in
          force and effect for a period of ninety (90)  consecutive days or
          more.  Landlord shall not be liable to Tenant if the latter is so
          dispossessed;  but any time that such  takes  place,  the  rental
          required of Tenant  shall be abated and that period of time shall
          be added as an extension to the term of the  Sublease;  provided,
          however,  that in no event  shall  the term of this  Sublease  be
          extended beyond the term of the Ground Lease; and

                    (b) The  assumption by the United States  Government or
          any agency or instrumentality  thereof of the operation,  control
          or use of Love  Field  Airport  for  national  defense  in such a
          manner  as to  preclude  Tenant,  for a  period  of  ninety  (90)
          consecutive  days or more, from using the Premises in the conduct
          of its  business.  Landlord  shall not be liable to Tenant if the
          latter is so dispossessed;  however, for any time that such takes
          place,  the rental  required of Tenant shall be abated,  and that
          period of time shall be added as an  extension of the Term of the
          Sublease.

     28.  Affirmative Covenants.

          28.1 Affirmative Covenants. In consideration for the improvements
to the Love Field Airport to be undertaken by the City with the  assistance
of Federal  funds to be provided to the City subject to certain  assurances
being made by tenants and subtenants doing business at the Airport,  Tenant
assures that it will undertake an affirmative action program as required by
14 CFR Part 152,  Subpart E, to ensure that no person  shall on the grounds
of  race,  creed,   color,   national  origin,  or  sex  be  excluded  from
participating  in any  employment  activities  covered  in 14 CFR Part 152,
Subpart E. Tenant assures that no person shall be excluded on these grounds
from  participating in or receiving the services or benefits of any program
or activity  covered by this subpart.  Tenant  assures that it will require
that its covered suborganizations provide assurances to Landlord and Ground
Lessor that such  suborganizations  similarly  will  undertake  affirmative
action   programs  and  that  they  will  require   assurances  from  their
suborganizations,  as required  by 14 CFR Part 152,  Subpart E, to the same
effect.

          28.2 No  Exclusion.  Tenant  assures  that  no  person  shall  be
excluded  from  participation  in,  denied the  benefits  of, or  otherwise
discriminated against in connection with the performance of the Sublease on
the grounds of race, color, national origin or sex.

          28.3 Review of Federal  Regulations.  Tenant acknowledges that it
has read the applicable  Federal  Regulations,  14 CFR Part 152, Subpart E,
and 49 CFR Part 23.

     30.  Landlord's Increased Leasehold Area.

          30.1  The  parties  hereby  acknowledge  that  a  portion  of the
Building and Improvements  which Tenant proposes to construct in accordance
with the Plans and  Specifications  will be situated  on property  which is
currently  being  leased to Tenant by the Ground  Lessor  pursuant  to that
certain Lease dated January 25, 1978, by and between Tenant, as tenant, and
the Ground  Lessor,  as landlord (the "K-C Lease").  Concurrently  with the
execution of this Sublease and effective as of the date hereof,  the Ground
Lessor will enter into a Second  Amendment  to Lease (the "K-C  Amendment")
with respect to the K-C Lease to delete the property  that is designated as
"Parcel E" on Exhibit B attached hereto (the "K-C Land"). The Ground Lessor
will further  amend the Ground Lease by entering  into a 1989  Amendment to
Love Field  Terminal and Air Cargo  Facility Lease and Agreement (the "1989
Amendment") with Landlord to provide that the Ground Lease will include the
K-C Land.

          30.2  The 1989  Amendment  will  provide  that  Landlord  will be
obligated  to pay the same  rental  rate for the K-C Land that  Tenant  was
required  to pay  under  the K-C  Lease at the  time of the K-C  Amendment.
Landlord and Tenant  hereby agree that the rent payable by Landlord for the
K-C Land pursuant to the 1989 Amendment, as well as any additional payments
or adjustments  relating to the K-C Land which are due and owing during the
Term  of  this  Sublease,  shall  be  paid by  Tenant  as  Additional  Rent
hereunder.  Tenant shall make such payments to Landlord  concurrently  with
the  payment by Tenant of the  monthly  installments  of Base Rent  payable
hereunder.

     31.  Miscellaneous.

          31.1 Landlord and Tenant.  The words  "Landlord"  and "Tenant" as
used herein shall include the permitted successors and assigns of each. The
plural number shall include the singular, and vice-versa. Words used in the
neuter gender include the masculine and feminine. If there is more than one
Tenant,  the  obligations  under this  Sublease  imposed on Tenant shall be
joint and several.  The captions  preceding  the articles of this  Sublease
have been inserted  solely as a matter of convenience  and such captions in
no way  define  or limit  the  scope or  intent  of any  provision  of this
Sublease.  As used herein, the term "including," when following any general
statement,  term or matter, shall not be construed to limit such statement,
term or matter  to the  specific  items or  matters  set forth  immediately
following  such  word  or to  similar  items  or  matters,  whether  or not
non-limiting  language (such as "without  limitation,"  or "but not limited
to," or words of similar import) is used with reference thereto, but rather
shall  be  deemed  to refer  to all  other  items  or  matters  that  could
reasonably  fall  within  the  broadest  possible  scope  of  such  general
statement, term or matter.

          31.2 Successors and Assigns. The terms,  covenants and conditions
contained in this Sublease  shall bind and inure to the benefit of Landlord
and Tenant and,  except as  otherwise  provided  herein,  their  respective
personal  representatives  and successors and assigns;  provided,  however,
upon the sale,  assignment or transfer by the Landlord  named herein (or by
any  subsequent  landlord) of its interest in the Real Property as owner or
ground lessee, including any transfer by operation of law, the Landlord (or
subsequent  landlord) shall be relieved from all subsequent  obligations or
liabilities  under this Sublease,  and all  obligations  subsequent to such
sale,  assignment or transfer (but not any obligations or liabilities  that
have accrued prior to the date of such sale,  assignment or transfer) shall
be binding upon the grantee, assignee or other transferee of such interest,
and any such grantee,  assignee or transferee,  by accepting such interest,
shall  be  deemed  to  have  assumed  such   subsequent   obligations   and
liabilities,  and Landlord shall also be relieved of all  responsibility or
liability  for any  security  deposit of Tenant held by  Landlord  upon the
transfer thereof to any grantee,  assignee or transferee in connection with
such sale assignment or transfer.

          31.3 Validity of Provisions. If any provision of this Sublease or
the application thereof to any person or circumstance shall, to any extent,
be  invalid  or  unenforceable,  the  remainder  of this  Sublease,  or the
application of such provision to persons or circumstances  other than those
as to which it is invalid or unenforceable,  shall not be affected thereby,
and each  provision of this Sublease  shall be valid and be enforced to the
full extent permitted by law.

          31.4  Applicable  Laws.  This  Sublease  shall be  construed  and
enforced in accordance with the laws of the State of Texas.

          31.5  Execution and Delivery.  Submission of this  instrument for
examination  or signature by Tenant does not constitute a reservation of or
an option for lease,  and it is not effective as a lease or otherwise until
execution  and delivery by both  Landlord and Tenant and approval by Ground
Lessor.  Tenant  shall not be  authorized  to record  this  Sublease or any
memorandum thereof without Landlord's prior written consent.

          31.6 No Representations or Warranties. This instrument, including
the  Exhibits  hereto,  which  are  hereby  made a part of  this  Sublease,
contains   the  entire   agreement   between  the  parties  and  all  prior
negotiations  and  agreements  are  merged  herein.  Neither  Landlord  nor
Landlord's agents have made any  representations or warranties with respect
to the Premises, the Building, the Real Property or this Sublease except as
may be expressly set forth herein, and no rights, easements or licenses are
or shall be acquired by Tenant by implication or otherwise unless expressly
set forth herein.

examination by Landlord or Ground Lessor,  of any plans,  specifications or
any other item to be reviewed,  approved, inspected or examined by Landlord
or Ground  Lessor under the terms of this  Sublease  (including  any of the
Exhibits  attached  hereto)  shall not  constitute  the  assumption  of any
responsibility for or any representation by Landlord or Ground Lessor as to
the accuracy or sufficiency of such plans, specifications or other item, or
the quality or suitability of such plans,  specifications or other item for
its or  their  intended  use.  Any such  review,  approval,  inspection  or
examination  by  Landlord  or  Ground  Lessor  is for the sole  purpose  of
protecting  Landlord's and Ground  Lessor's  interests under this Sublease,
and  neither  Tenant  nor any  person or entity  claiming  through or under

fails to perform any of its obligations under this Sublease or in the event
a dispute arises  concerning the meaning or interpretation of any provision
of this Sublease,  the defaulting party or the party not prevailing in such

incurred  by the  other  party in  enforcing  or  establishing  its  rights
hereunder,  including,  without  limitation,  court  costs  and  reasonable
counsel fees.

conditions herein specified so far as applicable.  Any holding over without
Landlord's express written consent shall constitute a continuing default by

expiration  or  termination  of the  Ground  Lease  shall be subject to the
approval of the Ground Lessor.

specifically  provided  to the  contrary  herein.  All  provisions  of this
Sublease  requiring  one party to  indemnify  the other with respect to any
matter, occurrence,  condition, event, claim or liability shall survive the
expiration or other termination of this Sublease.

          31.14 Time is of Essence.  Time is of the essence with respect to
the  performance  of the  obligations of the parties hereto as set forth in
this Sublease and all Exhibits hereto.

          31.15 Approval of Ground Lessor.  Notwithstanding anything to the
contrary  contained herein,  this Sublease shall not become effective,  and
the  parties  shall not have any  obligations  or  liabilities  under or in
connection  with this  Sublease,  unless and until this Sublease shall have
received the written  approval of the Ground  Lessor and all  mortgagees or
trust deed beneficiaries presently holding any lien on or security interest
in all or any  part of the  Real  Property.  Landlord  shall  use its  best
efforts to secure such approval, provided that Landlord shall not be deemed
to have  agreed  to pay any  consideration  for such  approval  to any such
mortgagee or beneficiary.  Upon receipt of such written approval,  Landlord
shall  promptly send Tenant  written  notice  thereof.  If this Sublease is
disapproved by the Ground Lessor or any such mortgagee or  beneficiary,  or
if written  notice of  approval  is not  received  from such  mortgagee  or
beneficiary  within  sixty  (60)  days from the date of  execution  of this
Sublease,  this Sublease shall be deemed  cancelled and of no further force
or effect,  and neither party shall have any further liability to the other

                 SUBLEASE OF FACILITY AT DALLAS LOVE FIELD

          This Sublease  (hereinafter  referred to as "Sublease") is by and
between Dallas Airmotive,  Inc., a Texas corporation  (hereinafter referred
to as  "Landlord"),  and the assignee of Ryder  Aviall,  and K-C  AVIATION,
INC., a Delaware  Corporation,  (hereinafter  referred to as  "Subtenant").

                                WITNESSETH

          WHEREAS, Landlord leases and shall continue to lease certain land
and improvements at Love Field ("Leased Premises") from the City of Dallas,
Texas, a Texas municipal corporation,  pursuant to an agreement (the "Prime
Lease")  entitled  "Lease  of  Land  and  Facilities  Agreement"  effective
November 1, 1993,  and the Amended and  Restated  Leasehold  Deed of Trust,
Security Agreement,  Assignment of Leases and Rents and Financing Statement
dated October 20, 1995 (the "Deed of Trust"); and 

          WHEREAS,  Landlord  desires  to  sublet a portion  of the  Leased
Premises to Subtenant,  and is permitted to do so under the Prime Lease and
the Deed of Trust;

          NOW THEREFORE, in consideration of the rent herein provided to be
paid by Subtenant  and such other mutual  covenants  and  consideration  as
herein  provided,  Landlord does hereby  sublease to Subtenant the property
described  below,  together with the  nonexclusive  right to use any common
improvements,  aprons,  taxiways,  ramps  and  access of  Landlord,  on the
following terms and conditions:

          (1) SUBLEASED  PREMISES.  Landlord hereby  subleases to Subtenant
that  certain  Building  at  8411  Lemmon  Avenue,  Dallas,  Texas,  75209,
containing  approximately  53,400 square feet of office,  shop,  and hangar
space, plus the parking area (the  cross-hatched  area as shown on attached
Exhibit "A"),  together with the non-exclusive right for ingress and egress
to the space, all of which is a portion of the Leased Premises as set forth
above, and is hereafter referred to as the "Property". A description of the
Property  is  attached  hereto as Exhibit A and is  incorporated  into this
Sublease by this reference.

          (2) TERM. This Sublease shall be for a term of approximately five
(5) years,  commencing  on  December 1, 1996 and ending on October 31, 2001
(hereinafter  referred  to  as  the  "Initial  Term").  Upon  the  faithful
performance  of all  obligations  under  this  Initial  Term by  Subtenant,
Subtenant  shall have the right and privilege to renew this Sublease for an
additional two (2) year period,  (the "First Extended Term")  commencing on
November 1, 2001, and expiring on October 31, 2003, provided that Subtenant
notifies  Landlord  of its  intent to renew at least 120 days  prior to the
expiration  of the  Initial  Term.  In the event  that  Landlord  renews or
extends the Prime Lease,  at the end of the First Extended Term,  Subtenant
shall have the right of first  refusal,  upon  written  notice at least 120
days prior to the end of the then  current  term,  to  continue to rent the
property on the same terms and  conditions  as herein  provided,  but for a
term and at a  rental  to be  renegotiated  at that  time.  Notwithstanding
anything to the contrary contained herein, the parties agree that Subtenant
may cancel this Sublease upon sixty (60) days prior written  notice and the
payment of (i) a termination fee of ninety thousand dollars ($90,000.00) if
termination occurs prior to or on October 31, 1997, eighty thousand dollars
($80,000.00)  if termination  occurs after October 31, 1997 and prior to or
on October 31, 1998,  seventy thousand dollars  ($70,000.00) if termination
occurs after  October 31, 1998 and prior to or on October 31,  1999,  sixty
thousand dollars  ($60,000.00) if termination occurs after October 31, 1999
and prior to or on October 31, 2000, fifty thousand dollars ($50,000.00) if
termination  occurs after  October 31, 2000,  plus (ii) an  additional  two
thousand dollars ($2,000.00) for each month that would have remained in the
Initial  Term  after  such  termination  (but  for such  termination).  The
termination  fee for the First Extended Term will be four times the average
monthly  rental  charged  during  the  first  renewal  period.   The  early
termination  compensation  shall be paid to Landlord,  in full, thirty (30)
days prior to the early termination date.

          (3) USE.  Subject  to the  other  terms  and  conditions  hereof,
Subtenant shall use the Property for air  transportation  related services,
parking,  maintenance,  fitting  and  storage of  aircraft  and  parking of
automobiles,  and other lawful  aviation  related  activities  permitted by
Lessor, and for no other purpose. In particular,  the Property shall not be
used for non-aviation  related activities without the prior written consent
of  Landlord,  which  may be  withheld  in its  reasonable  discretion.  In
addition,  Subtenant shall not occupy or permit the use of the Property for
any  unlawful or  hazardous  purposes or permit any activity to exist which
could constitute a nuisance to others, or increase the cost of insurance to
Landlord.

          (4) IMPROVEMENTS.  Except as set forth on the attached Exhibit B,
Subtenant  shall not make any  improvements  or alterations to the Property
without  the  prior  written  consent  of  Landlord,  which  shall  not  be
unreasonably  withheld or  delayed,  except any  improvements  or series of
improvements costing in the aggregate less than $20,000.00 shall require no
approval.

               (a)  Prior to  entering  into any  contract  for such  work,
Subtenant  shall first submit a written request to Landlord for approval of
conceptual plans  (hereinafter  referred to as "Construction  Application")
together with complete drawings and specifications of the proposed work and
the name of the contractor to whom Subtenant proposes to award the contract
for such work. Such approval shall not be unreasonably withheld or delayed.
Subtenant  further  agrees  that it will  obtain  a  "Performance  Bond and
Payment  Bond"  from all  contractors  if  requested  by the City of Dallas
and/or reasonably requested by Landlord.

               (b) Subtenant  shall include in all  construction  contracts
entered into by it in connection with any work at the Property, a provision
requiring the contractor to indemnify and hold harmless Landlord,  the City
of Dallas,  any  successor-in-interest,  as their interests may appear, and
their directors,  officers, agents, and employees against losses occasioned
by death,  injury to persons or damages to  property,  arising out of or in
connection  with the performance of any or all of such  construction  work,
against  the  risk of loss  or  damage  to the  construction  prior  to the
completion  thereof,  and  against  the losses  resulting  from  claims and
demands by third persons arising out of the performance of the construction
work; and Subtenant  shall require all  contractors to carry such insurance
as may be  reasonably  required  by the City of  Dallas  or  Landlord.  The
provisions of this subparagraph shall not apply to the extent the foregoing
are caused by the sole  negligence or breach of  obligations by the parties
indemnified in this paragraph.

               (c) Subtenant  agrees that all work to be performed by it or
its  contractors,  including all  workmanship  and  materials,  shall be of
first-class quality and shall be performed in compliance with all plans and
specifications  reviewed and  approved by Landlord,  and such work shall be
subject to Landlord's  inspection.  Subtenant shall assume the risk of loss
or damage to all such work prior to the completion thereof and shall repair
or replace  any such loss or damage  without  cost to  Landlord.  Subtenant
shall deliver to Landlord progress reports of Subtenant's work and shall at
all times during the term of this Sublease keep drawings  thereof  current,
showing thereon any changes or modifications made in or to the improvements
constructed on the Leased  Property all in accordance  with Paragraphs 4(f)
and 4(g) of the Prime Lease as they apply to Subtenant.

               (d) Subtenant  shall  discharge  promptly all obligations to
contractors, subcontractors,  materialmen, workmen and/or other persons for
all  work  performed  and for  materials  furnished  for or on  account  of
Subtenant.  Nothing in this Sublease  shall limit the right of Subtenant to
contest any claims of contractor,  subcontractor,  materialmen,  workmen or
other person without being considered in breach hereof.

               (e) Subtenant  acknowledges that the creation,  noticing, or
filing or the  attempt to create,  notice or file any claim  arising out of
improvements to the Property  against the Property is expressly  prohibited
in Landlord's  Prime Sublease.  Accordingly,  Subtenant  agrees to insert a
provision  precluding  the  imposition  of such  liens  into all  contracts
entered into for work, promptly remove and discharge any such lien or claim
and to indemnify  and hold  harmless  the  Landlord  from any and all loss,
cost,  damage or claim that may be  incurred by  Landlord  where  Subtenant
failed to abide by this provision.

               (f)  Landlord  agrees  to  perform  and pay for up to  fifty
thousand dollars  ($50,000.00) of hangar,  shop,  and/or office repairs and
improvements  including,  but not limited to,  painting the exterior of the
hangar and Seal Coating and striping the parking lots,  before December 31,
1996.  Should the cost of the above named  repairs and  improvements  total
less than the sum of fifty thousand dollars  ($50,000.00),  Landlord agrees
to pay Subtenant any excess to use toward  additional  improvements  of the
Property, in Subtenant's discretion.

          Subtenant shall propose to Landlord those Subtenant  improvements
and  Landlord  shall not  withhold  approval  as long as they  qualify as a
capital expense which can be amortized by Landlord using generally accepted
methods and principles of accounting.

          Landlord and Subtenant agree to exchange freely  contractor bids,
invoices, supporting cost data and/or receipted payments, as necessary, for
the mutual  monitoring  and  accounting of the  individual  and  cumulative
expenditures  up to the fifty  thousand  dollars  ($50,000.00)  referred to
hereinabove.

          (5)  MAINTENANCE   AND  REPAIRS.   Other  than  the  repairs  and
improvements  to be made as described  above,  Subtenant  has inspected the
Property,  and  agrees to accept  the  Property  in the same  condition  as
received  and to maintain  the  Property as provided in this  Section  with
reasonable  and  ordinary  wear and tear and loss or  damage  from  fire or
casualty excepted.  Landlord will be responsible and pay for (including any
necessary  maintenance,  repair, or replacement of) the building structural
components, ramps, taxi ways, parking areas, sidewalks and driveways on the
premises.  Landlord  will also be  responsible  to perform  and pay for the
significant  repair  and/or  replacement  of  the  mechanical,  electrical,
plumbing, air conditioning,  ventilation, and heating systems on the Leased
Premises.  Subject to the  foregoing,  Subtenant  will be  responsible  for
routine and preventative maintenance of the facilities,  including, but not
limited to,  janitorial  service,  minor  repairs to  air-conditioning  and
heating units, electrical, plumbing and grounds upkeep. Notwithstanding the
foregoing  responsibilities  of the Landlord,  but subject to the waiver of
subrogation and claims contained herein,  Subtenant  understands and agrees
that the Landlord shall not be responsible for any repairs  necessitated by
the  negligence  or  willful  or  wanton  misconduct  of the  Subtenant  or
Subtenant's employees, agents or invitees.

          (6) INSPECTION.  Subtenant  agrees that,  with  reasonable  prior
notice, Landlord or the City of Dallas, its agents or representatives,  may
enter upon the Property at any reasonable time for any reasonable  purpose,
and Subtenant  agrees to cooperate with them. In addition,  Subtenant shall
provide  Landlord,  upon written  request from Landlord,  with a listing of
Subtenant  contacts  and  telephone  numbers  for  emergency  access to the
Property. Subtenant shall have the right to accompany anyone inspecting the
Property.  Landlord agrees to treat Subtenant's  activities as confidential
in nature and not to disclose such activities to third parties.

          (7)  RENT.  Subtenant  shall pay to  Landlord  as  monthly  rent,

          Notwithstanding  the  foregoing,  the  parties  agree  that  this
section  shall not prohibit  Subtenant  from  purchasing  its aviation fuel
requirements   elsewhere   should   Landlord   be  unable  to  supply  such
requirements as herein provided  anytime,  or should  Subtenant's  aircraft
require  fueling at a location  other than  Dallas  Love  Field,  or should
Subtenant's  customers  require  a  fueling  source  other  than  Landlord.
Furthermore,  Landlord  shall  not be liable to  Subtenant  for  Landlord's
inability to provide  Subtenant  with aircraft fuel for reasons  beyond the
control of Landlord during the term hereof.

          Subtenant's  failure to abide by its obligation to purchase fuel,
as outlined above,  where such failure  continues for 15 days after written
notice from Landlord  shall entitle the Landlord to terminate this Sublease
or recover monies from Subtenant equal to one hundred  twenty-five  percent
(125%) of the amount  which would have been  charged by  Landlord  for fuel
purchased in violation of the covenant.

          (9)  INSURANCE.   Subtenant  shall  maintain  commercial  general
liability  insurance in an amount no less than $1,000,000,  naming the City
of  Dallas  and  Landlord  as  additional  insureds  with  regard  to their
interests in this  Sublease.  In  addition,  Subtenant  shall  maintain any
statutorily   required  Worker's   Compensation  and  Employer's  Liability
Insurance.  Landlord  shall  provide "All Risk" fire and extended  coverage
casualty  insurance.  Subtenant  agrees to obtain such other  insurance  as
Landlord may  reasonably  require  after  taking into  account  Subtenant's
activities at the Property.

          Certificates  of the insurance  required above shall be delivered
to  Landlord  prior to  Subtenant's  occupancy  of the  Property,  and such
certificates  shall  provide  that the City of Dallas  and  Landlord  shall
receive no less than  fifteen (15) days prior  written  notice prior to the
cancellation,   modification  or  expiration  of  said  policy.   Insurance
requirements,  as they apply to Subtenant under the terms of this Sublease,
shall be consistent with the insurance requirements set forth in Attachment
I to Landlord's  Prime Lease,  a copy of which  Attachment I is attached to
this Sublease.

          LANDLORD  AND  SUBTENANT  HEREBY  WAIVE ANY RIGHTS  EACH MAY HAVE
AGAINST THE OTHER ON ACCOUNT OF ANY LOSS OR DAMAGE  OCCASIONED  TO LANDLORD
OR  SUBTENANT,  AS THE CASE MAY BE  (WHETHER  OR NOT SUCH LOSS OR DAMAGE IS
CAUSED BY THE NEGLIGENCE OR FAULT OF THE OTHER PARTY),  TO THEIR RESPECTIVE
REAL OR  PERSONAL  PROPERTY,  INCLUDING  THE  PROPERTY  (AS DEFINED IN THIS
SUBLEASE),  ITS CONTENTS OR ANY OTHER PORTION OF THE PROPERTY  ARISING FROM
ANY RISK THAT WOULD BE COVERED BY THE  STANDARD  FORM OF FIRE AND  EXTENDED
COVERAGE  INSURANCE  USED IN THE  STATE OF TEXAS AT THE TIME OF THE LOSS OR
DAMAGE.  If a party waiving  rights under this paragraph is carrying a fire
and extended  coverage  insurance  policy in the standard  form used in the
State of Texas and an  amendment  to such  standard  form is  passed,  such
amendment shall be deemed not a part of such standard form until it applies
to the policy being carried by the waiving party.  The parties hereto each,
on behalf of their respective  insurance companies insuring the property of
either  Landlord or  Subtenant  against  any such loss,  waive any right of
subrogation  that it may have against the other  party.  Each party to this
Lease agrees  immediately  to give to each such insurance  company  written
notification  of  the  terms  of  the  mutual  waivers  contained  in  this
paragraph,  and to have  said  insurance  policies  properly  endorsed,  if
necessary,  to prevent the  invalidation  of said  insurance  coverages  by
reason of said waivers.  This paragraph shall control over any provision in
or  applicable  to this  Sublease  which is,  may be or may appear to be in
conflict with this paragraph.

          (10) TAXES. Subtenant shall pay, before delinquent,  all taxes on
its equipment, inventory, movable fixtures, furniture and personal property
that may be located at the Property or Love Field.

          (11) SUBLETTING AND ASSIGNMENT.  Subtenant may sublet, assign, or
share the Property with another entity only with  Landlord's  prior written
consent.  Any  request  for such  consent  shall  set  forth  all  relevant
information  regarding  the  entity,  the  nature  of its  operations,  its
financial  condition,  and at least  five (5) credit  references.  Upon any
subletting  or  assignment,  Landlord  shall be entitled  to receive  fifty
percent (50%) of all rental received by Subtenant in excess of that paid by
Subtenant  hereunder  and one hundred  percent  (100%) of all fuel  revenue
without  rebate or discount  for  gallons  delivered  to non K.C.  Aviation
controlled  airplanes  that  may  be  stored,  receiving  maintenance,   or
otherwise located at the Property on Love Field. Furthermore,  in the event
of an assignment or subletting, Subtenant shall remain fully liable for the
performance  of  all  obligations  and  liabilities  under  this  Sublease.
Occupancy  of  all or  part  of  the  Property  by  parent,  subsidiary  or
affiliated  companies of  Subtenant  shall not be deemed an  assignment  or
subletting.

          Notwithstanding the foregoing,  Landlord reserves the right, upon
notice and request from  Subtenant for the  subletting or assignment of its
interest  under this Sublease,  to terminate  this Sublease,  whereupon the
Sublease shall terminate sixty (60) days after such notice,  provided, this
termination  right  shall  be of  no  effect  if  Subtenant  withdraws  its
subletting  request within thirty (30) days after receipt of written notice
from Landlord of Landlord's election to terminate the Sublease.

          (12) UTILITIES.  Landlord shall provide utilities to the Property
in sufficient  amounts for the reasonable use of the Property by Subtenant.
Notwithstanding  same,  Subtenant  shall  be  responsible  for  paying  all
telephone charges,  and utilities will be directly metered to Subtenant and
Subtenant will remit directly to provider.

          (13)  TERMINATION.  Landlord reserves the right to terminate this
Sublease  before the end of its term if any of the following  circumstances
shall occur:

               (a) Subtenant  shall fail to make any payment due under this
Sublease  on the date that same is due and shall not cure such  failure for
fifteen (15) days after written notice thereof.

               (b)  Subtenant  shall fail to meet and observe any  material
term,  condition  or  covenant  of this  Sublease  and  shall not cure such
failure  within thirty (30) days after written  notice  thereof or, if such
failure  cannot  reasonably  be cured  within the said thirty (30) days and
Subtenant  shall not have commenced to cure such failure within said thirty
(30) days and shall not  thereafter,  with  reasonable  diligence  and good
faith, proceed to cure such failure.

               (c)  Subtenant  shall  become  insolvent,  or  shall  make a
transfer in fraud of creditors, or shall make an assignment for the benefit
of  creditors,  or a receiver  or  trustee  shall be  appointed  for all or
substantially all of the assets of Subtenant.

               (d)  Subtenant  shall  file  a  voluntary  petition,  or  an
involuntary petition is filed against Subtenant, in bankruptcy,  where such
suit is not dismissed within sixty (60) days after such filing.

               (e) The Prime Lease  between the City of Dallas and Landlord
terminates.

               (f)  Subtenant  commits any act or fails to perform any act,
the consequence of which is to cause Landlord to be in default of its Prime
Lease with the City of Dallas,  which  default is not cured within the time
periods provided in the Prime Lease.

          (14)  REMEDIES.  With  the  exception  of 13(e)  above,  upon the
occurrence of any of the events giving Landlord the right to terminate this
Sublease,  Landlord  shall have the option to pursue any one or more of the
following  remedies  without any notice or demand other than as required in
the section above.  

               (a) Terminate this Sublease,  in which event Subtenant shall
immediately,  upon written notice,  surrender the Property to Landlord, and
if Subtenant fails to do so, Landlord may,  without  prejudice to any other
remedy  which it may  have for  possession  or  rent,  enter  upon and take
possession  of the  Property  and  expel or remove  Subtenant  or any other
persons who may be occupying the Property or any part thereof.

               (b) Terminate this Sublease,  in which event Subtenant shall
pay Landlord the cancellation amount due under paragraph 2 of this Sublease
as liquidated  damages and as Landlord's  sole and exclusive  remedy solely
for the rents that  otherwise  would have  become due  hereunder  after the
termination  of  this  Sublease.  Such  liquidated  damages  shall  not  be
Landlord's sole remedy for any damages owed by Tenant that arose or accrued
during the Lease term.

               (c) Pursue all remedies  available  under  applicable  state
law.

          (15)  COST  OF  ENFORCEMENT.   The  court  costs  and  reasonable
attorney's  fees  incurred by either party in a successful  prosecution  or
defense of any legal or equitable  proceedings to construe this Sublease or
enforce any right or obligation  arising from it shall become an obligation
and payable from the other party.


          (16) COVENANT OF QUIET ENJOYMENT.  Landlord agrees that,  subject
to the terms of its Prime Lease with the City of Dallas,  and the terms and
conditions  of  this  Sublease,   upon  the  faithful  performance  of  its
obligations  hereunder,  Subtenant shall have and enjoy peaceful possession
and use of the Property.  The Landlord  shall use its best efforts to cause
the Prime Lease to remain in effect.

          (17)  WAIVER.  Any  failure or neglect on the part of Landlord or
Subtenant  to enforce  this  Sublease  shall not be taken or construed as a
waiver of its rights hereunder.

          (18)  SURRENDER  OF  PROPERTY.  Subtenant  agrees to deliver  the
Property to Landlord on the date of  cessation  of this  Sublease,  whether
such be by termination, expiration, or otherwise, promptly and in as good a
condition as received as of the  commencement of this Sublease,  reasonable
wear and  tear  and  damage  or loss by fire or  other  casualty  excepted.
Subtenant  shall be  allowed  fifteen  (15) days after the end date of this
Sublease to remove personalty, trade fixtures, tools, machinery, equipment,
portable buildings, materials and supplies from the Property.

          (19) INDEMNIFICATION.

               (a) As a  condition  hereof,  Subtenant  agrees to, and does
hereby,  indemnify,  defend and hold Landlord and the City of Dallas, their
directors,  officers,  agents and employees,  harmless  against any and all
claims,  suits,  judgments,  fines,  costs and expenses for personal injury
(including death),  property damage or other harm, brought or sought by any
person,  entity  or any  governmental  agency  that may  arise  out of,  be
incident to or occasioned by 1) Subtenant's use, occupancy, maintenance, or
construction on the Property, or Subtenant's installations and improvements
to the  Property,  or (with  respect to the City of Dallas) from any act or
omission  of  any  representative,   officer,  agent,  invitee,   employee,
contractor,  or subcontractor  of Subtenant,  or (with respect to Landlord)
from  any   negligent   or   strictly   liable  act  or   omission  of  any
representative,   officer,   agent,   invitee,   employee,   contractor  or
subcontractor  of Subtenant,  or 2) Subtenant's  breach of any of the terms
and provisions of this Sublease, or 3) any negligent or strictly liable act
or  omission of  Subtenant,  its  directors,  officers,  invitees,  agents,
contractors and subcontractors in any type of use, occupancy maintenance or
construction of the Property.  The indemnity provided for in this paragraph
shall not apply to any  liability  resulting  from the sole  negligence  or
fault  of  Landlord  or the  City  of  Dallas,  or  their  representatives,
officers, agents, invitees,  employees,  contractors or subcontractors.  In
the  event  of  joint  or  coincidental  negligence  or  fault  of both the
Subtenant and the Landlord  and/or the City of Dallas,  responsibility  and
indemnity,  if any, shall be allocated comparatively in accordance with the
portion of  responsibility  attributable to each party,  without,  however,
waiving any  governmental  immunity  available  to the City of Dallas under
Texas law and without waiving any defenses of the parties under Texas law.

               (b) The City of Dallas  assumes  no  responsibility  for any
property  placed  in or on the  Property,  and the City of Dallas is hereby
expressly  released and discharged from any and all liability for any loss,
injury or damage to persons or property  that may be sustained by reason of
the  use and  occupancy  of the  Property  and/or  Love  Field  under  this
Sublease,  unless  same is caused by the  negligence  or willful act of the
City  of  Dallas  or  its  officers,   invitees,  agents,  contractors  and
subcontractors, or by breach of contract by the City of Dallas.

               (c) Landlord agrees to and does hereby indemnify, defend and
hold harmless  Subtenant,  its directors,  officers,  agents and employees,
from any and all claims,  suits,  judgments,  fines, costs and expenses for
personal injury (including  death),  property damage or other harm, brought
or sought by any person,  entity, or any governmental agency that may arise
out of, be incident  to or  occasioned  by 1)  Landlord's  use,  occupancy,
maintenance,  or construction on the Property, or Landlord's  installations
and improvements to the Property,  or from any negligent or strictly liable
act or omission of any representative,  officer, agent, invitee,  employee,
contractor or subcontractor of Landlord,  or 2) Landlord's breach of any of
the terms and provisions of this Sublease,  or 3) any negligent or strictly
liable act or omission of  Landlord,  its  directors,  officers,  invitees,
agents,  contractors  and  subcontractors  in any  type of  use,  occupancy
maintenance or construction  of the Property,  or 4) any gross negligent or
strictly  liable act or  omission of  Landlord,  its  directors,  officers,
invitees,  agents,  contractors,  and  subcontractors  in any  type of use,
occupancy, or construction of the Property.

          (20)  CONDEMNATION.  If,  during the term of this  Sublease,  any
portion of the Property (such that the remainder cannot  reasonably used as
Subtenant  then  intends and  desires)  shall be taken by  condemnation  or
eminent domain  proceedings,  then this Sublease shall  terminate as of the
date  of  such  taking,  and  all  rights,  titles,  interests,  covenants,
agreements and obligations of the parties hereto thereafter  accruing shall
terminate  with  Subtenant  hereby  assigning  and  releasing  to  Landlord
Subtenant's rights to any compensation for the taking;  provided,  however,
any  condemnation  award for Subtenant's  personal  property and relocation
costs are not assigned to Landlord and shall belong to Subtenant.

          (21)   NON-DISCRIMINATION.   Subtenant,   as  a   part   of   the
consideration hereof, does hereby covenant and agree, as a covenant running
with the land, that (1) no person on the grounds of race,  color,  national
origin,  or handicap  shall be excluded from  participation  in, denied the
benefits of, or be otherwise  subjected to discrimination in the use of any
facilities  operated or used by Subtenant at Love Field; (2) that Subtenant
shall use the Property in compliance  with all  requirements  imposed by or
pursuant  to 49 CFR  Part  21,  "Nondiscrimination  in  Federally  Assisted
Programs of the Department of  Transportation",  as said regulations may be
amended.

          (22) SIGNS.  All exterior  signs shall comply with the  pertinent
City  ordinances,  and shall also have prior written  approval of Landlord,
which shall not be unreasonably  withheld, and the Director of Aviation for
the City of Dallas. Unless otherwise  specifically  authorized,  they shall
conform in general  appearance  with the existing signs displayed at Dallas
Love Field.  Upon the  termination of the Sublease,  Subtenant shall remove
the signage as required by the  Director of Aviation  and/or  Landlord,  at
Subtenant's  expense. If Subtenant fails to do as required,  Landlord shall
have the option but not the  obligation  of removing the signs and the cost
thereof shall be due from Subtenant to Landlord upon demand.

          (23)  GOVERNMENTAL  REQUIREMENTS-RULES  & REGULATIONS.  Subtenant
agrees to obtain and maintain in effect from all  governmental  authorities
having jurisdiction, all licenses,  certificates, and permits necessary for
its operations. In addition, Subtenant agrees to comply with all applicable
Federal,   State  and  local  laws  and   regulations  in  connection  with
Subtenant's use and occupancy of the Property.

          (24) NO REPRESENTATIONS.  Neither Landlord nor the City of Dallas
has made, nor does hereby make,  any  representation,  guarantee,  promise,
agreement,  or  warranty  of any  kind  whatsoever,  whether  expressed  or
implied,  oral  or  written,  past,  present  or  future,  relating  to  or
concerning the nature,  quality or condition of the Property, the income to
be derived, the suitability of the Property for the uses allowed under this
Sublease, or merchantability or fitness for a particular purpose.

          (25) ENVIRONMENTAL CONCERNS.  Subtenant agrees to comply strictly
with all applicable environmental laws, rules and regulations pertaining to
its  Sublease  and  occupancy  of Property at Love Field and agrees to, and
does hereby,  indemnify and hold  harmless  Landlord and the City of Dallas
from any and all loss, cost,  damage or claim alleged or sustained by them,
or either of them, to the extent arising out of Subtenant's  non-compliance
with  applicable  environmental  laws,  rules and  regulations or breach of
terms  of  this   Sublease.   Furthermore,   Subtenant   acknowledges   the
relationship  of  Landlord  to the City of Dallas  and  agrees  that if any
environmental remediation is required,  Landlord shall have the right, upon
notice,  unless an emergency  situation  exists,  in which event, no notice
shall be required, to undertake and complete such remediation to the extent
required  under the applicable  laws.  Subtenant  shall promptly  reimburse
Landlord for any and all reasonable  and documented  costs incurred in such
action to the extent such action was  required as a result of  Subtenant or
Subtenant's  invitees',  customers'  or  guests'  use or  occupancy  of the
Property.  Landlord  shall use its best efforts not to  interfere  with the
operations  of  Subtenant.   If  remediation  interferes  with  Subtenant's
operations, an equitable rent adjustment will be made.

          Notwithstanding   any  of  the   foregoing,   any   environmental
remediation,  response or other action, obligation or liability required in
or around the Property resulting directly or indirectly from any actions or
omissions of parties other than Subtenant prior to the commencement date of
this  Sublease  shall  not be the  obligation,  duty or  responsibility  of
Subtenant.  Landlord agrees to defend,  indemnify and hold  Subtenant,  its
officers, agents,  contractors,  and subcontractors  (Indemnitees) harmless
from and against, and to reimburse  Indemnitees with respect to any and all
claims and expenses (including  reasonable attorney's fees and court costs)
of any and every kind or character,  known or unknown, fixed or contingent,
asserted  against or incurred by  Indemnitees at any time and, from time to
time, by reason of, in connection with or arising out of any act, omission,
event or  circumstance  relating  to  health,  safety,  or the  environment
existing or  occurring  prior to the  commencement  date of this  Sublease.
Landlord shall have and bear the burden of proof to show that any actual or
alleged liabilities or obligations related to environmental  matters relate
to the period after the  commencement  date of this Sublease and/or are the
responsibility  of Subtenant,  Landlord and Subtenant  agreeing  there is a
rebuttable presumption to the contrary.

          (26)  SUBORDINATION.  Although the  obligations  of Subtenant are
fully set forth herein,  or by specific  reference to the Prime Lease, this
Sublease  shall be subject  and  subordinate  in all  respects to the Prime
Lease and the  rights of the City of Dallas  thereunder.  Additionally,  at
Landlord's  option,  this Sublease shall be subject and  subordinate to any
future mortgage or encumbrance which Landlord may incur on the Property, so
long as such subordination does not interfere with Subtenant's right of use
and peaceful  possession of the Property through the completion of the term
of Sublease.

          (27)  SUCCESSORS  AND  ASSIGNS.  Subject  to the  limitations  of
assignment herein contained,  this Sublease shall be binding upon and inure
the benefit of the parties hereto, their respective successors and assigns.

the base rent for that calendar month shall be prorated between  $15,839.33
and $16,433.31  based upon the  applicable  number of days in that calendar
month which occur, respectively, before and after the last day of such 36th
month.

     (b) There shall be no security deposit.

     1.06  PERMITTED USE.  General office use and jet engine  overhaul (but
with no testing of jet  engines at the leased  premises),  and no other use
without the prior  written  consent of Lessor,  which  consent shall not be
unreasonably withheld or delayed. With regard to Lessee's use of the leased
premises  for  jet  engine  overhaul,  Lessor's  inclusion  of  same  as  a
"Permitted  Use"  refers  only  to  permission  from  Lessor,   subject  to
Applicable  Laws (as  defined in section  3.03 below) and  applicable  deed
restrictions, if any; and in no way should it be deemed as a representation
or warranty from Lessor that such use is permitted  under  Applicable  Laws
and applicable deed restrictions.

                             ARTICLE 2.00 RENT

     2.01 BASE RENT.  Lessee agrees,  without  demand,  setoff or deduction
(except as expressly  provided in this Lease),  to pay monthly as base rent
during the term of this Lease the sum of money set forth in section 1.04 of
this Lease,  which amount  shall be payable to Lessor at the address  shown
above.  One  monthly  installment  of rent shall be due and  payable on the
Commencement  Date  for  the  first  month's  rent  and  a  likely  monthly
installment  shall be due and  payable  on or before  the first day of each
calendar  month  succeeding the  Commencement  Date during the term of this
Lease;  provided,  if the Commencement  Date or the expiration date of this
Lease  should be a date other than the first day of a calendar  month,  the
monthly  rental  set  forth  above  shall  be  prorated  to the end of that
calendar month, and all succeeding installments of rent shall be payable on
or before the first day of each  succeeding  calendar month during the term
of this Lease.  Lessee shall pay, as  additional  rent,  all other sums due
under this Lease.

     2.02 PROPERTY TAX AND INSURANCE ESCALATIONS. In the event Lessor's Tax
and Insurance  Expenses for the leased premises shall, in any calendar year
during the term of this Lease, exceed the actual Tax and Insurance Expenses
paid or incurred by Lessor for the leased  premises for the  calendar  year
1997 (the "Base Year"), Lessee agrees to pay as additional rent such excess
Tax and  Insurance  Expenses.  Accordingly,  Lessee  shall not be liable or
responsible for payment of any excess Tax and Insurance  Expenses  pursuant
to  this  section  2.02  during  the  Base  Year  and  such   liability  or
responsibility  shall not begin accruing  until January 1, 1998;  provided,
however,  that if the Tax and Insurance Expenses paid or incurred by Lessor
for the leased premises for the calendar year 1998 are less than those paid
or incurred by Lessor for the  calendar  year 1997,  the Base Year shall be
the calendar year 1998.  Notwithstanding the foregoing, with regard to that
portion of Tax and Insurance  Expenses  comprised of real  property  taxes,
Lessee shall only be  responsible  for such tax expenses to the extent they
exceed the  greater of (i) the actual tax  expenses  incurred by Lessor for
the leased  premises for the Base Year or (ii) the tax expenses  that would
have been incurred by Lessor for the leased  premises for the Base Year had
this Lease been in effect and had Lessee  been in  occupancy  of the leased
premises  on January 1, 1997.  Lessor may  invoice  Lessee  monthly for the
estimated Tax and Insurance  Expenses for each calendar year,  which amount
shall be  adjusted  each year  based  upon  anticipated  Tax and  Insurance
Expenses.  Within nine months  following the close of each  calendar  year,
Lessor shall provide Lessee an accounting  showing in reasonable detail all
computations  of additional  rent due under this section.  In the event the
accounting  shows  that the total of the  monthly  payments  made by Lessee
exceeds the amount of additional rent due by Lessee under this section, the
accounting  shall be accompanied  by a refund.  In the event the accounting
shows that the total of the  monthly  payments  made by Lessee is less than
the amount of additional rent due by Lessee under this section, the account
shall be accompanied by an invoice for the additional rent. Notwithstanding
any  other  provision  in this  Lease,  during  the year in which the Lease
terminates, Lessor, prior to the termination date, shall have the option to
invoice  Lessee for the excess Tax and  Insurance  Expenses  based upon the
previous year's Tax and Insurance  Expenses.  If this Lease shall terminate
on a day other  than the last day of a  calendar  year,  the  amount of any
additional  rent  payable  by Lessee  applicable  to the year in which such
termination  shall  occur shall be prorated on the ratio that the number of
days  from the  commencement  of the  calendar  year to and  including  the
termination  date bears to 365.  Lessee  shall  have the right,  at its own
expense and within a  reasonable  time (not to exceed six (6) months  after
Lessee's  receipt of an  invoice  from  Lessor),  to audit  Lessor's  books
relevant to the additional  rent payable under this section upon reasonable
notice to Lessor,  but not more than once each calendar year, and if all of
the  following  apply  to such  audit:  (i) the  audit is  conducted  by an
independent  certified  accountant  who is  compensated  at an hourly  rate
(i.e., as opposed to a contingency  method of  compensation),  and (ii) the
audit  discloses an  overpayment  by Lessee of more than five percent (5%),
the Lessor shall pay for the reasonable  cost of such audit.  Lessee agrees
to pay any  additional  rent due under this section within thirty (30) days
following receipt of the invoice or accounting showing additional rent due.

     2.03  DEFINITION  OF TAX AND  INSURANCE  EXPENSES.  The term  "Tax and
Insurance Expenses" shall mean all real property taxes, general and special
assessments  (with  Lessor being  required to either elect the  installment
treatment  for special  assessments  or otherwise  treat Tax and  Insurance
Expenses as though Lessor had elected the installment treatment with regard
to special assessments) and taxes or assessments on rentals, including dues
and assessments by means of deed restrictions  and/or owners'  associations
which accrue against the leased premises during the term of this Lease; and
all  insurance  premiums  Lessor is  required  to pay or  reasonably  deems
necessary to pay, including public liability insurance, with respect to the
leased premises.

     2.04 LATE  PAYMENT  CHARGE.  Other  remedies  for  nonpayment  of rent
notwithstanding,  if the  monthly  base rental  payment is not  received by
Lessor on or  before  the tenth day of the month for which the rent is due,
or if any other  payment  of rent due Lessor by Lessee is not  received  by
Lessor on or before the tenth day  following the date on which such payment
is due to Lessor,  a late payment charge of three percent (3%) of such past
due amount  shall  become due and payable in addition to such  amounts owed
under this Lease.

     2.05 INCREASE IN INSURANCE  PREMIUMS.  If an increase in any insurance
premiums  paid by Lessor for the leased  premises is caused by Lessee's use
of the leased premises in a manner other than as set forth in section 1.06,
or if Lessee  vacates  the leased  premises  and causes an increase in such
premiums,  then  Lessee  shall pay as  additional  rent the  amount of such
increase to Lessor.

     2.06 HOLDING OVER. In the event that Lessee does not vacate the leased
premises  upon the  expiration  of this Lease,  Lessee shall be a tenant at
will for the holdover  period and all of the terms and  provisions  of this
Lease shall be applicable during that period,  except that Lessee shall pay
Lessor as base rent for the period of such  holdover an amount equal to one
and one-fourth (1 1/4) times the base rent which would have been payable by
Lessee had the  holdover  period been a part of the  original  term of this
Lease.  Lessee  agrees to vacate and deliver the leased  premises to Lessor
upon Lessee's  receipt of notice from Lessor to vacate.  No holding over by
Lessee,  whether  with or without the consent of Lessor,  shall  operate to
extend the term of this Lease.

                       ARTICLE 3.00 OCCUPANCY AND USE

     3.01 USE.  Lessee  warrants and  represents  to Lessor that the leased
premises  shall  be used  and  occupied  only for the  purposes  which  are
permitted in section 1.06. Lessee shall occupy the leased premises, conduct
its  business and control its agents,  employees,  invitees and visitors in
such a manner  as is  lawful,  reputable  and will not  create a  nuisance.
Lessee shall neither permit any waste on the leased  premises nor allow the
leased  premises  to be used  in any way  which  would,  in the  reasonable
opinion of Lessor,  be extra hazardous on account of fire or which would in
any way increase or render void the fire insurance on the leased  premises.
If at any time during the term of this Lease the State  Board of  Insurance
or other insurance  authority imposes an additional penalty or surcharge in
Lessor's  insurance  premiums  because of Lessee's  original or  subsequent
placement or use of storage  racks or bins,  method of storage or nature of
Lessee's  inventory  or any other act of  Lessee,  Lessee  agrees to pay as
additional rent the increase in Lessor's insurance premiums.  With specific
regard to the hazardous or possibly hazardous  materials used in connection
with Lessee's  intended  business at the leased premises,  Lessee agrees as
follows:  (i) Lessee shall include in Lessee's Work  (hereinafter  defined)
whatever  fixtures and  improvements  may be required by Applicable Laws in
connection with the handling of such  materials;  (ii) Lessee shall use all
such  materials  in  accordance  with  all  Applicable  Laws;  (iii) at the
conclusion  of the term of this  Lease,  Lessee  shall  provide to Lessor a
Phase  I  environmental  survey  of  the  leased  premises  prepared  by an
independent environmental engineer reasonably acceptable to Lessor, who has
been fully apprised of Lessee's operations at the leased premises; and (iv)
Lessee,  at its sole cost and  expense,  shall (a)  cause  such  additional
studies to be performed on the leased  premises as are  recommended by such
environmental  survey to  investigate  or assess the  obligations of Lessee
under  Applicable  Laws  pertaining  to the  environment  based on Lessee's
operations  at the leased  premises  or  conditions  observed at the leased
premises, and (b) perform or cause to be performed such remedial work as is
recommended  by  such  environmental  survey,  to the  extent  required  by
Applicable  Laws pertaining to the  environment,  to the extent and only to
the extent that such  remedial  work is necessary as the result of the acts
of Lessee, its agents, employees or invitees during the term of this Lease.

     3.02  SIGNS.  No sign of any type or  description  shall  be  erected,
placed or  painted  in or about the  leased  premises  except  those  signs
submitted to Lessor in writing and approved by Lessor in writing, and which
signs are in conformance  with Lessor's sign criteria  established  for the
leased premises.  Notwithstanding the foregoing,  Lessor agrees that Lessee
shall be allowed to erect or install,  at Lessee's  sole cost and  expense,
exterior  signage  on the  leased  premises,  provided  that such  exterior
signage shall in all respects be in compliance with all Applicable Laws and
applicable deed  restrictions (as to which Lessor makes no  representations
or  warranties to Lessee),  as well as being  approved in writing by Lessor
with respect to location, size, materials,  color, graphics and layout. Any
such signage shall be constructed and maintained by Lessee at its sole cost
and  expense,  in  accordance  with  any  and  all  applicable  restrictive
covenants, approval rights of any existing property association and any and
all  other  applicable  laws,  rules,  ordinances  and  regulations  and in
accordance  with  Lessor's  signage  criteria as the same may be reasonably
amended by Lessor from time to time. Lessor agrees that its approval of any
signage requested by Lessee shall not be unreasonably withheld or delayed.

     3.03 COMPLIANCE WITH LAWS, RULES AND REGULATIONS.  Lessee, at Lessee's
sole cost and  expense,  shall  comply with all laws,  ordinances,  orders,
rules and  regulations  of state,  federal,  municipal or other agencies or
bodies having  jurisdiction over use, condition and occupancy of the leased
premises.  Lessee  must use and  maintain  the leased  premises in a clean,
careful, safe and proper manner and in compliance with all applicable laws,
ordinances,  orders, rules and regulations of all governmental entities and
regulatory agencies (collectively, "Applicable Laws"), including Applicable
Laws pertaining to health,  safety,  disabled  persons and the environment;
provided, however, that Lessee shall not be required to make any structural
changes  or  repairs  to the  leased  premises  unless  the  need  for such
structural changes or repairs is caused by Lessee,  its agents,  employees,
invitees or others for whom Lessee is responsible pursuant to the terms and
provisions  of  this  Lease.   Notwithstanding  anything  to  the  contrary
contained  elsewhere  in this  section  3.03,  it is  expressly  agreed and
understood that Lessee's obligation to comply with all Applicable Laws does
not apply to any violations of Applicable Laws which were in effect and the
leased  premises  was  not  in  compliance  with  or  were  being  violated
immediately  prior  to  the  time  Lessee  accepted  the  leased  premises,
including without  limitation,  any existing  environmental  contamination.
Further,  Lessor,  at Lessor's sole cost and expense,  shall be responsible
for any structural  changes or other repairs,  alterations or other actions
necessary to bring the leased premises into compliance with Applicable Laws
as in effect  immediately  prior to the time  Lessee  accepted  the  leased
premises,  including without limitation,  all Applicable Laws pertaining to
health,  safety,  the environment and disabled persons.  Lessee will comply
with the rules and  regulations  of the leased  premises  adopted by Lessor
which are set forth on Exhibit "B"  attached to this  Lease.  Lessor  shall
have the right at all times to change  and amend the rules and  regulations
in any reasonable  manner as may be deemed advisable for the safety,  care,
cleanliness,  preservation of good order and operation or use of the leased
premises.  All changes and  amendments to the rules and  regulations of the
leased  premises  will be sent by Lessor to  Lessee  in  writing  and shall
thereafter be carried out and observed by Lessee.

     3.04 WARRANTY OF POSSESSION. Lessor warrants that it has the right and
authority to execute this Lease,  and Lessee,  upon payment of the required
rents and  subject  to the  terms,  conditions,  covenants  and  agreements
contained  in this  Lease,  shall have  possession  of the leased  premises
during  the full term of this  Lease as well as any  extension  or  renewal
thereof.  Lessor shall not be responsible  for the acts or omissions of any
third party that may  interfere  with  Lessee's  use and  enjoyment  of the
leased premises;  provided,  however,  Lessor agrees to utilize  reasonable
efforts in a good faith attempt to prevent any third party from interfering
with or  continuing  to interfere  with  Lessee's use and  enjoyment of the
leased premises.

     3.05 INSPECTION.  Lessor or its authorized agents shall at any and all
reasonable times have the right to enter the leased premises to inspect the
same,  to supply any service to be  provided by Lessor,  to show the leased
premises to  prospective  purchasers  or lessees  (which  right to show the
leased  premises to  prospective  lessees  shall be limited to the last one
hundred  eighty [180] days of the term of this Lease,  as the same may have
been  extended  hereunder),  and to alter,  improve  or repair  the  leased
premises in  accordance  with the terms of this Lease;  provided,  however,
that except in the event of an emergency,  Lessor or its authorized  agents
shall at all times be accompanied  by a  representative  of Lessee.  Lessee
hereby  waives  any claim for  damages  for injury or  inconvenience  to or
interference  with Lessee's  business,  any loss of occupancy or use of the
leased premises, and any other loss occasioned thereby. Lessor shall at all
times have and retain a key with which to unlock all of the doors in,  upon
and about the leased premises. Lessee shall not change Lessor's lock system
or in any other manner prohibit  Lessor from entering the leased  premises.
Lessor  shall have the right to use any and all means which Lessor may deem
proper  to open the  leased  premises  in an  emergency  without  liability
therefor.  Notwithstanding  anything to the contrary contained hereinabove,
Lessor agrees to (a) utilize  reasonable  efforts (except in the event that
an emergency  either exists or reasonably  appears to exist or be imminent)
to give  Lessee  twenty-four  (24)  hours  advance  written  notice  of any
intended entry by Lessor or its agents or  representatives  upon the leased
premises during regular business hours and (b) utilize  reasonable  efforts
in a good faith attempt to cause as little  interruption  and  interference
with the  conduct  of  business  by Lessee  in the  leased  premises  as is

current  commitment  for title  insurance or other  comparable  evidence of
title to the leased  premises  issued by a title  company and copies of all
underlying  documents  shown as  exceptions  to title  affecting the leased
premises.  In the event that such title commitment or underlying  exception
documents are  unacceptable to Lessee for any reason,  in Lessee's sole and
absolute  discretion,  Lessee shall have the right, at Lessee's option,  to
terminate this Lease by delivering a written  termination  notice to Lessor
within ten (10) days after  Lessee's  receipt of such title  commitment and
underlying exception documents.

                     ARTICLE 4.00 UTILITIES AND SERVICE

     4.01.  UTILITIES.  Lessee shall pay the cost of all utility  services,

exterior walls (excluding windows,  window glass, plate glass and doors) of
the building  comprising a part of the leased premises,  except for damages
caused by the  negligence of Lessee,  its agents,  employees,  contractors,
guests and  invitees  which  damage  shall be repaired at the sole cost and
expense of Lessee and which will  constitute  additional rent due hereunder
upon demand by Lessor therefor. Lessor agrees to utilize reasonable efforts
to effectuate and promptly  complete any maintenance or repairs required to
be performed by Lessor hereunder in a manner  calculated to cause as little
interruption and interference with the conduct of business by Lessee in the
leased premises as is reasonably practicable.  In addition, if Lessor fails
to perform any of its repair and maintenance obligations hereunder and such
default is not cured by Lessor in accordance  with the terms and provisions
of section 11.03  hereinbelow,  then Lessee shall have the right to perform
such repair and  maintenance  obligations  as are  reasonably  necessary to
either (a)  prevent  any damage to  Lessee's  inventory  or other  personal
property  and/or (b) obviate any material  and adverse  effects to Lessee's

replacements  promptly  as required  herein,  Lessor may, at its option and
after the  expiration of any  applicable  notice and cure period,  make the
repairs and  replacements  and the cost of such  repairs  and  replacements

Work"),  with all of such ACM Abatement  Work to be performed and completed
in accordance  with Applicable  Laws.  Except for the completion of the ACM
Abatement  Work and  Lessor's  warranty  that all  portions  of the  leased

unacceptable  to Lessee  for any  reason,  in  Lessee's  sole and  absolute
discretion,  Lessee shall have the right, at Lessee's option,  to terminate
this Lease by delivering a written  termination notice to Lessor within ten
(10) days after Lessee's receipt of the Environmental Survey. Regardless of
whether or not Lessee  terminates  this Lease  pursuant to the  immediately
preceding   sentence,   Lessee  shall  promptly   deliver  a  copy  of  the
Environmental Survey to Lessor.

     6.03  LESSEE  IMPROVEMENTS.  Upon  Lessee's  occupancy  of the  leased
premises,  Lessee may  perform  the work  ("Lessee's  Work")  described  in
Exhibit "C" attached hereto and made a part hereof,  which Lessee's Work is
hereby deemed approved by Lessor for all purposes.  Lessor hereby agrees to
perform,  at its  sole  cost  and  expense,  any  and all  future  removal,
encapsulation  or other  abatement or handling of asbestos  and/or asbestos
containing  material  as is  required  by  Applicable  Laws or which is not
unreasonably  requested by Lessee in connection  with (i) Lessee's Work, or
(ii) any  future  alterations,  additions  or  improvements  to the  leased
premises  permitted  by  the  terms  of  this  Lease.  Notwithstanding  the
foregoing,  however,  Lessee  agrees  that,  with the  exception of the ACM
Abatement  Work  prescribed  in section 6.1 above,  Lessee will not request
that Lessor  remove,  encapsulate  or abate any  asbestos  and/or  asbestos
containing  material  referred to in the ACM Survey  (e.g.,  the  wallboard
joint  compound and paint texture or the resilient  flooring and associated
mastic  referenced  in the summary set forth on page 4 of the ACM  Survey),
unless  the  building  materials  associated  with such items are (a) being
altered  by Lessee in such a manner  that the  asbestos  contained  in such
items  will  be  disturbed  or  (b)  are  being   removed.   Such  removal,
encapsulation  or other  abatement or handling shall be performed by Lessor
(i) in  accordance  with the schedule of such work  established  by Lessee,
provided Lessee is not unreasonable in establishing such schedule, and (ii)
in a manner that will minimize  interference  with Lessee's business in the
leased  premises.  Except  with  respect  to  Lessee's  Work and  interior,
non-structural alterations or additions to the leased premises costing less
than $50,000,  Lessee shall not make or allow to be made any alterations or
physical additions in or to the leased premises without first obtaining the
written consent of Lessor, which consent shall not be unreasonably withheld
or delayed.  Any  alterations,  physical  additions or  improvements to the
leased  premises made by Lessee shall at once become the property of Lessor
and shall be surrendered to Lessor upon the termination of this Lease. This
clause shall not apply to moveable  equipment,  furniture or trade fixtures
owned by  Lessee,  which may be removed by Lessee at the end of the term of
this  Lease if  Lessee is not then in  default  and if such  equipment  and
furniture are not then subject to any other  rights,  liens and interest of
Lessor.

                    ARTICLE 7.00 CASUALTY AND INSURANCE

     7.01   SUBSTANTIAL   DESTRUCTION.   If  the   building   and/or  other
improvements  comprising  a part of the leased  premises  should be totally
destroyed by fire or other  casualty,  or if the leased  premises should be
damaged so that rebuilding  cannot  reasonably be  substantially  completed
within ninety (90) working days after the date of written  notification  by
Lessee to Lessor of the  destruction,  this Lease  shall,  at the option of
Lessor or Lessee  [exercised  by  written  notice to the other  party on or
before   that  date  which  is  thirty   (30)  days  after  the  damage  or
destruction],  terminate  and the rent  shall be abated  for the  unexpired
portion of the Lease, effective as of the date of the written notification.

     7.02 PARTIAL DESTRUCTION.

     (a)  If the building  and/or other  improvements  comprising a part of
          the leased premises should be partially  damaged by fire or other
          casualty,  and  rebuilding or repairs can reasonably be completed
          within  ninety  (90)  working  days  from  the  date  of  written
          notification by Lessee to Lessor of the  destruction,  this Lease
          shall not  terminate,  and Lessor shall  proceed with  reasonable
          diligence to rebuild or repair the building or other improvements
          to  substantially  the same condition in which they existed prior
          to the damage. However,  Lessor's duty or obligation to repair or
          rebuild the leased  premises shall be limited to the extent,  and
          only to the  extent,  that  Lessor  actually  receives  insurance
          proceeds in connection with any such damage or destruction  after
          payment  of all of  Lessor's  reasonable  costs and  expenses  in
          obtaining such insurance proceeds.

     (b)  Notwithstanding  the  preceding  subsection,  in the  event  that
          Lessor fails to substantially  complete the necessary  repairs or
          rebuilding  within one hundred twenty (120) working days from the
          date  of  written   notification  by  Lessee  to  Lessor  of  the
          destruction,  Lessee  may at its option  terminate  this Lease by
          delivering  written  notice of  termination to Lessor before such
          time  as  Lessor  has  substantially  completed  the  repairs  or
          rebuilding, whereupon all rights and obligations under this Lease
          shall cease to exist.

     (c)  If the leased  premises  are to be rebuilt  or  repaired  and are
          untenantable  in whole or in part  following the damage,  and the
          damage or destruction  was not caused or contributed to by act or
          negligence of Lessee, its agents,  employees,  invitees, or those
          for whom Lessee is responsible, the rent payable under this Lease
          during the period for which the leased premises are  untenantable
          shall be adjusted to such an extent as may be fair and reasonable
          under the circumstances.

     7.3 INSURANCE.

     (a)  Lessee must  procure  and  maintain  throughout  the term of this
          Lease and any  extensions  or  renewals of the term of this Lease
          commercial   general  liability   insurance   (including  blanket
          contractual liability coverage), which shall cover any claims for
          bodily  injury,  death  and/or  property  damage  occurring in or
          resulting from any occurrence on the leased  premises,  including
          injury,  death and/or  damage  caused by the  condition of or any
          defect in the building or other improvements comprising a part of
          the leased premises.  The policies evidencing such insurance must
          be in form reasonably satisfactory to Lessor, must name Lessor as
          an  additional  insured,  must be issued by  insurance  companies
          reasonably  acceptable  to  Lessor,  and  must  afford  immediate
          protection to the limit of not less than $1,000,000 per accident.
          With respect to each policy evidencing such liability  insurance,
          Lessee  shall  obtain  any  available   endorsements   reasonably
          required  by Lessor.  Lessee  shall also  deliver the policy or a
          certificate  evidencing the same to Lessor prior to occupying the
          leased   premises  or   commencing   the   construction   of  any
          improvements  thereon or in the building comprising a part of the
          leased  premises,  and  Lessee  shall  deliver a  certificate  of
          renewal  from the  applicable  insurer at least ten days prior to
          the  expiration of the policy.  In addition,  Lessee shall obtain
          and deliver to Lessor a written obligation on the part of each of
          its  insurance  companies to notify Lessor at least 10 days prior
          to any cancellation of or material change to such insurance.

     (b)  Lessor shall at all times during the term of this Lease  maintain
          a policy or  policies  of  insurance  with the  premiums  paid in
          advance,   issued  by  and  binding  upon  an  insurance  company
          reasonably  acceptable to Lessee,  insuring the building  against
          all risk of direct  physical  loss in an amount equal to the full
          replacement  cost of the building  structure and its improvements
          as of the  date  of  the  loss;  provided,  Lessor  shall  not be
          obligated  in any way or manner to insure any  personal  property
          (including,  but not limited to, any furniture,  machinery, goods
          or supplies) of Lessee upon or within the leased premises. Lessor
          shall at times during the term of this Lease maintain a policy or
          policies of general liability insurance with the premiums paid in
          advance,   issued  by  and  binding  upon  an  insurance  company
          reasonably   acceptable  to  Lessee,  with  respect  to  Lessor's
          activities  in the  leased  premises,  such  insurance  to afford
          minimum   protection  of  not  less  than  One  Million   Dollars
          ($1,000,000.00)  combined single limit coverage of bodily injury,
          death, property damage or a combination thereof. Lessor shall not
          be required  to  maintain  insurance  against  thefts  within the
          leased premises.  Lessee accepts  responsibility  for keeping all
          personal property and equipment in the leased premises adequately
          insured  and  for  maintaining  adequate  business   interruption
          insurance. Lessee shall have no right in claim to the proceeds of
          any policy of insurance maintained by Lessor even though the cost
          of such  insurance  is borne by Lessee  as set  forth in  Article
          2.00.

     7.04 WAIVER OF  SUBROGATION.  Anything  in this Lease to the  contrary
notwithstanding,  Lessor and Lessee  hereby waive and release each other of
and from any and all right of recovery,  claim,  action or cause of action,
against each other, their agents,  officers and employees,  for any loss or
damage that is  insurable  pursuant to  customary  insurance  coverage  and
occurs to the  leased  premises,  improvements  to the leased  premises  or
personal  property  within  the leased  premises,  by reason of fire or the
elements,  regardless of cause or origin, including negligence of Lessor or
Lessee and their agents,  officers and employees;  provided,  however, that
this  waiver of  subrogation  shall not  apply to the  deductible  (up to a
maximum  deductible  of  $50,000)  which  is  applicable  to the  insurance
coverage  of  each  respective  waiving  party.  Lessor  and  Lessee  agree
immediately to give their respective  insurance companies which have issued
policies of insurance  covering all risk of direct  physical loss,  written
notice of the terms of the mutual waivers contained in this section, and to
have the insurance policies properly endorsed, if necessary, to prevent the
invalidation  of the insurance  coverages by reason of the mutual  waivers.
WITHOUT  LIMITATION,  IT IS THE  INTENTION  OF LESSOR AND  LESSEE  THAT THE
FOREGOING  RELEASES BY LESSOR AND LESSEE BE EFFECTIVE  NOTWITHSTANDING  ANY
NEGLIGENCE (BUT NOT GROSS NEGLIGENCE) ON THE PART OF THE OTHER PARTY.

     7.05 HOLD HARMLESS. Lessee shall indemnify and hold Lessor harmless of
and from any loss,  attorneys' fees, expenses,  claims, fines, suits, costs
and  liability of every kind arising  because of any bodily  injury,  death
and/or damage to property  occurring in or resulting from any occurrence in
the leased  premises  during the term of this Lease and any holdover period
save and  except  for any costs  occasioned  by the  negligence  or willful
wrongful  acts of Lessor or  Lessor's  agents or  employees.  Except to the
extent  caused  by a breach  of this  Lease or the  negligence  or  willful
wrongful acts of Lessor or Lessor's  agents or employees,  Lessor shall not
be liable to Lessee's employees,  agents, invitees,  licensees or visitors,
or to any other  person,  for any injury to person or damage to property on
or about the leased premises  caused by any act or omission of Lessee,  its
agents,  servants or  employees,  or of any other person  entering upon the
leased premises under express or implied invitation by Lessee, or caused by
the improvements located on the leased premises becoming out of repair, the
failure or  cessation  of any  service  provided  by  Lessor,  or caused by
leakage of gas, oil,  water or steam or by  electricity  emanating from the
leased premises.

                         ARTICLE 8.00 CONDEMNATION

     8.01  SUBSTANTIAL  TAKING.  If all or a substantial part of the leased
premises  are  taken  for  any  public  or   quasi-public   use  under  any
governmental law, ordinance or regulation, or by right of eminent domain or
by purchase in lieu  thereof,  and the taking would  prevent or  materially
interfere with the use of the leased  premises for the purpose for which it
is then  being  used,  this  Lease  shall at the option of Lessor or Lessee
[exercised  by  written  notice to the other  party on or before  that date
which is thirty (30) days after the date of the taking]  terminate  and the
rent shall be abated during the unexpired  portion of this Lease  effective
on the date  physical  possession  is taken  by the  condemning  authority.
Lessee  shall have no claim to the  condemnation  award or proceeds in lieu
thereof.  Notwithstanding  anything to the contrary contained  hereinabove,
Lessee shall have the right to recover from the condemning  authority,  but
not Lessor,  any  compensation  as may be  separately  awarded to Lessee on
account of moving and relocation  expenses and  depreciation to and removal
of Lessee's  physical  property and all other  interest  and property  (but
expressly  excluding  any  improvements  constructed  and  installed in the
leased  premises and any other property which would  otherwise be or become
the property of Lessor upon the  termination  or  expiration of this Lease)
for which Lessee is entitled to compensation from such condemning authority
under common law or applicable  statutes,  so long as and conditioned  upon
any award to Lessee  not  having the  effect of  reducing  the award  which
Lessor  would  otherwise  be  entitled  to  receive  under  common  law  or
applicable statutes.

     8.02  PARTIAL  TAKING.  If a portion of the leased  premises  shall be
taken for any  public or  quasi-public  use  under  any  governmental  law,
ordinance or  regulation,  or by right of eminent  domain or by purchase in
lieu thereof,  and this Lease is not  terminated as provided in section 8.1
above,  Lessor  shall  restore  and  reconstruct  the  building  and  other
improvements  on the leased  premises  to the extent  necessary  to make it
reasonably  tenantable.  The rent  payable  under  this  Lease  during  the
unexpired portion of the term shall be adjusted to such an extent as may be
fair and reasonable under the circumstances.  Lessee shall have no claim to
the  condemnation  award  or  proceeds  in  lieu  thereof.  Notwithstanding
anything set forth herein to the contrary,  Lessor's  obligation to restore
and/or  reconstruct the building and other  improvements under this section
8.02  shall  be  limited  to the  extent,  and  only  to the  extent,  that
condemnation  proceeds are actually  received by Lessor in connection  with
any such  taking  after  payment of all of  Lessor's  reasonable  costs and
expenses in obtaining such condemnation  proceeds. In the event that Lessor
fails to restore or reconstruct the building and other  improvements on the
leased  premises within one hundred twenty (120) working days from the date
of such  taking,  Lessee  shall have the right to  terminate  this Lease by
delivering  written notice of such  termination to Lessor.  Notwithstanding
anything to the contrary contained hereinabove, Lessee shall have the right
to recover from the condemning authority,  but not Lessor, any compensation
as may be separately  awarded to Lessee on account of moving and relocation
expenses and depreciation to and removal of Lessee's  physical property and
all other interest and property (but expressly  excluding any  improvements
constructed  and  installed in the leased  premises and any other  property
which  would  otherwise  be or  become  the  property  of  Lessor  upon the
termination  or  expiration  of this Lease) for which Lessee is entitled to
compensation from such condemning  authority under common law or applicable
statutes,  so long as and  conditioned  upon any award to Lessee not having
the effect of reducing the award which  Lessor would  otherwise be entitled
to receive under common law or applicable statutes.

                    ARTICLE 9.00 ASSIGNMENT OR SUBLEASE

     9.01 LESSOR ASSIGNMENT.  Lessor shall have the right to sell, transfer
or assign, in whole or in part, its rights and obligations under this Lease
and in the leased  premises.  Any such sale,  transfer or assignment  shall
operate to release  Lessor  from any and all  liabilities  under this Lease
arising after the date of such sale, assignment or transfer.  Additionally,
Lessee shall continue to make payment of all rent and other amounts due and
payable from Lessee to Lessor  hereunder to the named Lessor at the address
set forth in section 1.05 hereinabove until such time as Lessee receives an
instrument  executed by both the Lessor and such  transferee  or  assignee,
giving  notice of such  transfer or  assignment  and  instructions  for the
delivery of payments and notices by Lessee to such  transferee  or assignee
and  affirming the  assumption  (by the  transferee or assignee  identified
therein) of all obligations and  responsibilities of Lessor under the Lease
which are properly  due,  performable,  allocable and  attributable  to any
period of time subsequent to the date of such transfer or conveyance.

     9.02 LESSEE ASSIGNMENT.  Lessee shall not assign, in whole or in part,
this Lease, or allow it to be assigned,  in whole or in part, or sublet the
leased premises,  in whole or in part, without the prior written consent of
Lessor (which consent shall not be unreasonably withheld or delayed). In no
event shall any such  assignment  or sublease  ever  release  Lessee or any
guarantor  from any  obligation or liability  hereunder;  moreover,  in the
event that Lessee shall  receive any payments from an assignee or sublessee
in excess of (i) the base rent and other  payments  required  to be paid by
Lessee  pursuant to this Lease and (ii) any  refurbishment,  commissions or
other  expenses  Lessee may incur in  connection  with such  assignment  or
subletting,  then Lessee shall promptly forward all such excess payments to
Lessor.  Notwithstanding  the foregoing  provisions of this Article 9.00 to
the  contrary,  Lessee  may from time to time,  without  Lessor's  consent,
assign this Lease or sublet the leased premises, or any portion thereof, to
any parent or  subsidiary  of Lessee or the  guarantor of this Lease or any
subsidiary  of a parent  corporation  of either  Lessee or the guarantor of
this Lease  (hereinafter  collectively  referred to as a "Related  Party").
Further, any sale or exchange of Lessee's stock on a nationally  recognized
exchange,  any  change  in  ownership  of  Lessee  as a result of a merger,
consolidation,  reorganization  or the exchange of stock  between  Lessee's
parent  company or a subsidiary of Lessee or of Lessee's  parent company or
the sale of all or substantially  all of Lessee's stock or assets shall not
be considered  an assignment  under this article 9.00 and Lessee shall have
no  obligation  to  obtain  Lessor's  consent  in the  event of any of such
events.

     9.03  CONDITIONS OF ASSIGNMENT.  If Lessee desires to assign or sublet
all or any part of the leased  premises,  Lessee shall so notify  Lessor at
least  fifteen (15) days in advance of the date on which Lessee  desires to
make such  assignment or sublease.  Lessee shall provide Lessor with a copy
of the proposed assignment or sublease and such information as Lessor might
request  concerning  the proposed  sublessee or assignee to allow Lessor to
make  informed  judgments  as  to  the  financial  condition,   reputation,
operations and general  desirability of the proposed sublessee or assignee.
Within ten (10) days after Lessor's receipt of Lessee's proposed assignment
or sublease and all required information  concerning the proposed sublessee
or assignee,  Lessor shall have the following  options:  (1) consent to the
proposed  assignment or sublease;  or (2) refuse to consent to the proposed
assignment  or  sublease,  which  refusal  shall  be  deemed  to have  been
exercised  unless Lessor gives Lessee written notice  providing  otherwise.
Upon  the  occurrence  of an event  of  default,  if all or any part of the
leased  premises are then  assigned or sublet,  Lessor,  in addition to any
other  remedies  provided  by this Lease or  provided  by law,  may, at its
option,  collect directly from the assignee or sublessee all rents becoming
due to Lessee  by reason of the  assignment  or  sublease.  Any  collection
directly by Lessor from the assignee or sublessee shall not be construed to
constitute  a  novation  or a release of Lessee or any  guarantor  from the
further  performance of its obligations under this Lease. The terms of this
section 9.03 shall not apply to an  assignment  or  subletting to a Related
Party.

     9.04 SUBORDINATION.  Lessee accepts this Lease subject and subordinate
to any  recorded  mortgage  or deed of trust  lien  presently  existing  or
hereafter  created upon the leased  premises  and to all existing  recorded
restrictions,  covenants,  easements  and  agreements  with  respect to the
leased premises, subject to and conditioned upon, Lessor causing any holder
of any lien(s) now or hereafter  affecting  the project or any part thereof
to execute and deliver the agreement  hereinafter described in this section
9.04.  Lessee  agrees  upon  demand  to  execute   additional   instruments
subordinating this Lease as Lessor may reasonably require. If the interests
of Lessor under this Lease shall be transferred by reason of foreclosure or
other proceedings for the enforcement of any mortgage or deed of trust lien
on the leased premises,  Lessee shall be bound to the transferee (sometimes
called the "Purchaser"),  under the terms, covenants and conditions of this
Lease for the balance of the term  remaining,  including any  extensions or
renewals,  with the same force and effect as if the  Purchaser  were Lessor
under this Lease,  and Lessee agrees to attorn to the Purchaser,  including
the  mortgagee  under  any such  mortgage  if it be the  Purchaser,  as its
Lessor. Provided further, as a material inducement to cause Lessee to enter
into this  Lease,  Lessor  agrees to cause the  holder of any  existing  or
future lien placed  against the leased  premises or any portion  thereof to
enter into an agreement with Lessee making this Lease expressly subject and
subordinate to such lien and all renewals,  modifications,  consolidations,
replacements  and  extensions  thereof,  wherein the Lessee  shall agree to
attorn  to the  Purchaser  at any  foreclosure  sale of such  lien and such
agreement shall contain a covenant  binding upon the holder of such lien to
the effect that,  as long as there shall be no event of default on the part
of Lessee entitling Lessor to terminate this Lease, or if any such event of
default exists, any time in which to cure the event of default as contained
herein shall not have  expired,  (a) this Lease shall not be  terminated or
modified in any respect whatsoever nor shall the rights of Lessee hereunder
or its occupancy of the leased premises be affected in any manner by reason
of such  lien or any  foreclosure  action or other  proceeding  that may be
instituted in connection  therewith or in lieu thereof and (b) Lessee shall
not be named by such holder as a defendant in any such  foreclosure  action
or other proceeding.  Lessee and Lessor agree to execute (together with any
future holder of any lien[s]  hereafter  placed against the leased premises
or any  portion  thereof),  within  thirty (30) days  following  receipt of
written  request  therefor from Lessor or Lessee (as the case may be), such
an agreement containing the aforesaid terms,  together with such additional
changes as the future holder of any such lien(s) may  otherwise  reasonably
require.

     9.05 ESTOPPEL  CERTIFICATES.  Lessee  agrees to furnish,  from time to
time,  within ten days after  receipt of a request  from Lessor or Lessor's
mortgagee, a statement certifying, if applicable, the following:  Lessee is
in  possession  of the  leased  premises;  the  Lease is in full  force and
effect;  the  Lease  is  unmodified  (or,  if  modified,   describing  such
modifications);  Lessee claims no present charge,  lien, or claim of offset
against rent;  the rent is paid for the current  month,  but is not prepaid
for more than one month and will not be prepaid  for more than one month in
advance; and there is no existing default by reason of some act or omission
by Lessor.  Lessor  agrees to furnish,  from time to time,  within ten days
after  receipt  of a  request  from  Lessee,  a  statement  certifying,  if
applicable, the following: the Lease is in full force and effect; the Lease
is unmodified  (or, if modified,  describing  such  modifications);  Lessor
claims no present  charge,  lien, or claim against  Lessee (other than base
rent and Tax and Insurance  Expenses);  and there is no existing default by
reason of some act or omission by Lessee.

                            ARTICLE 10.00 LIENS

     10.01  LESSOR'S  LIEN.  Lessor  hereby  waives any  statutory or other
landlord's  lien upon  Lessee's  personal  property  or any other  property
located  within  the leased  premises  that may be  available  to Lessor to
secure the performance of Lessee's obligations under this Lease.

                     ARTICLE 11.00 DEFAULT AND REMEDIES

     11.01 DEFAULT BY LESSEE. The following shall be deemed to be events of
default by Lessee  under this Lease:  (1) Lessee shall fail to pay when due
any  installment  of rent or any other  payment  required  pursuant to this
Lease and the  failure  is not cured  within  ten (10) days  after  written
notice  thereof;  (2) Lessee shall abandon any  substantial  portion of the
leased premises;  (3) Lessee shall fail to comply with any term,  provision
or covenant of this Lease,  other than the payment of rent, and the failure
is not cured within thirty (30) days after written notice to Lessee,  or if
such failure cannot reasonably be cured within such thirty (30) day period,
within such period of time as is reasonably necessary;  provided,  however,
that Lessee  commences the cure of such failure within such thirty (30) day
period and diligently pursues such cure to completion; or (4) Lessee or any
guarantor under this lease shall file a petition or be adjudged bankrupt or
insolvent  under any applicable  federal or state  bankruptcy or insolvency
law or admit that it cannot meet its financial  obligations  as they become
due; or a receiver or trustee shall be appointed  for all or  substantially
all of the assets of Lessee;  or Lessee  shall make a transfer  in fraud of
creditors  or  shall  make an  assignment  for the  benefit  of  creditors,
generally.

     11.02 REMEDIES OF LESSOR.  Upon the occurrence of any event of default
set forth in this Lease, Lessor shall have the option without any notice to
Lessee (except as expressly  provided  below) and with or without  judicial
process, to pursue any one or more of the remedies set forth herein without
any notice or demand: (1) Lessor may pursue all of its rights at law and in
equity.  (2)  Lessor may enter upon and take  custodial  possession  of the
leased premises,  by picking or changing locks if necessary,  and lock out,
expel or remove Lessee and any other person who may be occupying all or any
part of the leased premises without being liable for any claim for damages,
and relet the  leased  premises  on behalf of Lessee and  receive  the rent
directly by reason of the reletting.  Lessee agrees to pay Lessor on demand
any  deficiency  that may arise by reason of any  reletting  of the  leased
premises;  further,  Lessee agrees to reimburse  Lessor for any  reasonable
expenditures  made by it in order to relet the leased premises,  including,
but not limited to,  remodeling and repair costs. (3) Lessor may enter upon
the leased  premises,  by picking or changing  locks if necessary,  without
being liable for any claim for damages, and do whatever Lessee is obligated
to do under the terms of this Lease.  Lessee agrees to reimburse  Lessor on
demand for any expenses which Lessor may incur in effecting compliance with
Lessee's obligations under this Lease;  further,  Lessee agrees that Lessor
shall not be liable for any  damages  resulting  to Lessee  from  effecting
compliance  with  Lessee's  obligations  under this  Lease.  (4) Lessor may
terminate this Lease, in which event Lessee shall immediately surrender the
leased  premises to Lessor,  and if Lessee  fails to  surrender  the leased
premises,  Lessor may,  without  prejudice to any other remedy which it may
have for possession or arrearages in rent enter upon and take possession of
the leased  premises,  by picking or changing locks if necessary,  and lock
out,  expel or remove  Lessee and any other person who may be occupying all
or any part of the leased  premises  without being liable for any claim for
damages.  With specific  regard to an  abandonment  by Lessee of the leased
premises or a  termination  of Lessee's  right to  possession of the leased
premises,  Lessor shall use  reasonable  efforts to mitigate its damages by
attempting  to relet the leased  premises;  however,  Lessor  shall have no
obligation  to agree to any lease  terms  which it  reasonably  deems to be
unacceptable,  nor shall Lessor be obligated to (i) travel outside a radius
of thirty (30) miles from  Dallas  County,  Texas,  in order to meet with a
prospective  tenant,  or (ii) expend monies for  finish-out  requested by a
prospective tenant unless Lessor in its reasonable discretion approves both
the lease terms and the credit of such prospective tenant.

     11.03  DEFAULT BY  LESSOR.  All  covenants  of Lessee in the Lease are
independent  covenants,  not conditioned upon Lessor's  satisfaction of its
obligations hereunder, except to the extent otherwise specifically provided
herein.  Lessee waives any statutory  lien it may have against the rent due
under this Lease or against Lessor's  property in Lessee's  possession.  If
Lessor  defaults in the  performance of any of its  obligations  under this
Lease, it will have thirty (30) days to cure after Lessee delivers  written
notice  to  Lessor  of the  default;  or if the  default  is of a nature to
require  more than  thirty  (30) days to remedy,  Lessor will have the time
reasonably necessary to cure it. Whenever a period of time is prescribed in
the Lease for action to be taken by Lessor or Lessee,  Lessor or Lessee, as
applicable,  will not be  liable or  responsible  for,  and there  shall be
excluded from the  computation  for any such period of time, any delays due
to strikes,  riots,  acts of God,  shortages  of labor or  materials,  war,
Applicable Laws or any other causes of any kind whatsoever which are beyond
the control of Lessor or Lessee, as applicable.

                         ARTICLE 12.00 DEFINITIONS

     12.01  ABANDON.  "Abandon"  means the vacating of all or a substantial
portion  of the  leased  premises  by  Lessee,  whether or not Lessee is in
default of the rental payments due under this Lease.

     12.02 ACT OF GOD OR FORCE MAJEURE.  An "act of God" or "force majeure"
is defined  for  purposes  of this Lease as  strikes,  lockouts,  sitdowns,
material  or labor  restrictions  by any  governmental  authority,  unusual
transportation delays, riots, floods,  washouts,  explosions,  earthquakes,
fire,  storms,  weather  (including wet grounds or inclement  weather which
prevents construction),  acts of the public enemy, wars,  insurrections and
any other cause not reasonably  within the control of Lessor or Lessee,  as
applicable,  and which by the exercise of due  diligence  Lessor is unable,
wholly or in part, to prevent or overcome.

     12.03  COMMENCEMENT  DATE.  "Commencement  Date" shall be the date set
forth  in  section  1.03.  The  Commencement   Date  shall  constitute  the
commencement  of the term of this  Lease for all  purposes,  whether or not
Lessee has actually taken possession. Notwithstanding anything set forth in
this Lease to the contrary,  all possession  and/or occupancy of the leased
premises by Lessee prior to the  Commencement  Date shall be subject to all
of the terms and  provisions  of this  Lease,  save and  except  only those
provisions requiring the payment of rent.

                        ARTICLE 13.00 MISCELLANEOUS

     13.01  WAIVER.  Failure  of Lessor or  Lessee to  declare  an event of
default  immediately upon its occurrence,  or delay in taking any action in
connection  with an event of default,  shall not constitute a waiver of the
default,  but  Lessor or  Lessee,  as  applicable,  shall have the right to
declare  the  default  at any time and take  such  action  as is  lawful or
authorized under this Lease. Pursuit of any one or more of the remedies set
forth in article 11.00 above shall not preclude  pursuit of any one or more
of the other remedies provided  elsewhere in this Lease or provided by law,
nor shall pursuit of any remedy constitute forfeiture or waiver of any rent
or damages  accruing to Lessor or Lessee by reason of the  violation of any
of the terms,  provisions or covenants of this Lease.  Failure by Lessor or
Lessee to enforce  one or more of the  remedies  provided  upon an event of
default  shall not be deemed or  construed  to  constitute  a waiver of the
default or of any other violation or breach of any of the terms, provisions
and covenants contained in this Lease.

     13.02  ACT OF GOD.  Lessor  or  Lessee,  as  applicable,  shall not be
required to perform any covenant or obligations in this Lease, or be liable
in damages to Lessee or Lessor,  as applicable,  so long as the performance
or  non-performance  of the covenant or  obligation  is delayed,  caused or
prevented  by an act of God,  force  majeure  or by  Lessee or  Lessor,  as
applicable.  Notwithstanding  anything to the contrary contained or implied
elsewhere herein, it is expressly agreed that the mere inability to pay any
monetary  amounts  shall  not be deemed  to  constitute  an "act of God" or
"force majeure" hereunder.

     13.03  ATTORNEYS'  FEES.  In the event  either  party  defaults in the
performance  of any of  the  terms,  covenants,  agreements  or  conditions
contained  in this  Lease  and the  other  party  places in the hands of an
attorney the  enforcement of all or any part of this Lease,  the collection
of any rent due or to  become  due or  recovery  of the  possession  of the
leased  premises,  the  non-prevailing  party agrees to pay the  prevailing
party's costs of collection,  including reasonable  attorneys' fees for the
services of the attorney, whether suit is actually filed or not.

     13.04  SUCCESSORS.  This Lease shall be binding  upon and inure to the
benefit  of  Lessor  and  Lessee  and  their  respective  heirs,   personal
representatives,  successors and permitted assigns. It is hereby covenanted
and agreed that should  Lessor's  interest in the leased  premises cease to
exist for any reason  during the term of this Lease,  then  notwithstanding
the happening of such event (subject to the terms and provisions of section
9.1 hereof),  this Lease  nevertheless  shall remain unimpaired and in full
force and effect,  and Lessee  hereunder agrees to attorn to the then owner
of the leased premises.

     13.05 CAPTIONS. The captions appearing in this Lease are inserted only
as a  matter  of  convenience  and in no way  define,  limit,  construe  or
describe the scope or intent of any section.

     13.06  NOTICE.  All rent and  other  payments  required  to be made by
Lessee  shall be payable to Lessor at the  initial  address  for Lessor set
forth in section 1.05, or at any other address within Dallas County, Texas,
as Lessor may specify  from time to time by written  notice.  All  payments
required  to be made by Lessor to Lessee  shall be payable to Lessee at the
initial  address  for  Lessee set forth in  section  1.05,  or at any other
address  within Dallas  County,  Texas,  as Lessee may specify from time to
time by written notice.  Any notice or document required or permitted to be
delivered by the terms of this Lease shall be deemed to be  delivered  when
actually  received at the office of the  intended  recipient or if earlier,
and regardless of whether or not actually received, two business days after
being deposited in the United States Mail, postage prepaid, certified mail,
return  receipt  requested,  addressed  to the  intended  recipient  at its
respective address set forth in section 1.05.

     13.07  SUBMISSION  OF LEASE.  Submission  of this  Lease to Lessee for
signature does not constitute a reservation of space or an option to lease.
This Lease is not effective  until execution by and delivery to both Lessor
and Lessee.

     13.08 ENTITY  AUTHORITY.  If Lessee or Lessor executes this Lease as a
corporation,  each of the persons  executing this Lease on behalf of Lessee
or Lessor, as applicable, does hereby personally represent and warrant that
Lessee  or  Lessor,  as  applicable,  is a  duly  authorized  and  existing
corporation,  that Lessee or Lessor,  as  applicable,  is  qualified  to do
business in the state in which the leased  premises are  located,  that the
corporation has full right and authority to enter this Lease, and that each
person signing on behalf of the  corporation is authorized to do so. In the
event any representation or warranty is false, all persons who execute this
Lease shall be liable, individually, as Lessee or Lessor, as applicable.

     13.09 SEVERABILITY.  If any provision of this Lease or the application
thereof to any person or circumstance  shall be invalid or unenforceable to
any  extent,  the  remainder  of this  Lease  and the  application  of such
provisions to other persons or circumstances  shall not be affected thereby
and shall be enforced to the greatest extent permitted by law.

     13.10  LESSOR'S  LIABILITY.  If Lessor shall be in default  under this
Lease and, if as a  consequence  of such  default,  Lessee shall  recover a
money judgment against Lessor, such judgment shall be satisfied only out of
the right,  title and interest of Lessor in the leased premises as the same
may  then be  encumbered  and  neither  Lessor  nor any  person  or  entity
comprising Lessor shall be liable for deficiency.  In no event shall Lessee
have the right to levy  execution  against  any  property of Lessor nor any
person or entity  comprising  Lessor  other than its interest in the leased
premises as herein expressly provided.

     13.11  INDEMNITY AND  DISCLOSURE.  Lessor agrees to indemnify and hold
harmless   Lessee  from  and  against  any  liability  or  claim,   whether
meritorious  or not,  arising with respect to any broker whose claim arises
by,  through or on behalf of Lessor,  including but not limited to, Herbert
D. Weitzman of The Weitzman Group (the "Broker"),  the Broker  representing
Lessor in  accordance  with a separate  written  agreement  executed by and
between  Broker and Lessor.  Lessee  agrees to indemnify  and hold harmless
Lessor from and against any liability or claim, whether meritorious or not,
arising with  respect to any broker  whose claim  arises by,  through or on
behalf of  Lessee,  save and  except  for the  Broker  who shall be paid by
Lessor as provided in the immediately preceding sentence and Greg Cannon of
Cushman & Wakefield, who shall be paid by the Broker pursuant to a separate
written  agreement  executed  by and  between  Greg  Cannon and the Broker.
Lessor, Broker and Herbert D. Weitzman hereby advise Lessee that Herbert D.
Weitzman is a principal in Lessor.

     13.12 GOVERNING LAW;  VENUE.  This Lease shall be governed by the laws
of the State of Texas.  Any legal  action  relating  to this Lease shall be
conducted in Dallas County, Texas.

     13.13  CONFIDENTIALITY.  Lessor  and  Lessee  hereby  agree to hold in
strictest  confidence  and refrain from  disclosing  to any third party the
economic terms and conditions of this Lease, other than to their attorneys,
accountants,   financial  advisors,  prospective  purchasers,   prospective
financial  sources,  prospective  assignees or sublessees or as required by
law.  Further,  Lessor  agrees that it will not publish or publicize in any
way (whether by press release,  newspaper or magazine article or otherwise)
the fact that Lessee has leased the leased  premises from  Lessor).  Either
party  shall  have the right to seek and obtain  from a court of  competent
jurisdiction,  in an action  for that  purpose,  a judgment  enjoining  and
prohibiting  the other party from  disclosing  confidential  information in
violation  of this  provision.  The party  bringing  such  action  shall be
entitled to recover its attorneys'  fees and court costs in any such action
in which it is successful.

                                                               EXHIBIT 99.1


           CAUTIONARY STATEMENT FOR PURPOSES OF THE "SAFE HARBOR"
          PROVISIONS OF THE PRIVATE SECURITIES REFORM ACT OF 1995
          -------------------------------------------------------


     Gulfstream  Aerospace  Corporation  (the  "Company"  or  "Gulfstream")
cautions  readers that the  important  factors set forth below,  as well as
factors  discussed  in  other  documents  filed  by the  Company  with  the
Securities and Exchange Commission (the "SEC"),  among others,  could cause
the Company's actual results to differ materially from statements contained
in this report,  future  filings by the Company with the SEC, the Company's
press releases and oral statements made by or on behalf of the Company.

     The words "estimate",  "project",  "anticipate",  "expect",  "intend",
"believe",  "target"  and  similar  expressions  are  intended  to identify
forward looking statements.  In addition, these factors relate specifically
to the  Company's  statements  regarding  earnings  per  share for 1998 and
subsequent years and the assumptions underlying those statements, including
assumptions  regarding  green  aircraft  deliveries,   completions,  margin
improvements, new aircraft sales and backlog stability.

AIRCRAFT PRODUCTION AND COMPLETION

     The Company  records  revenue from the sale of a new "green"  aircraft
(i.e.,  before  exterior  painting and  installation  of customer  selected
interiors and optional  avionics)  when the green  aircraft is delivered to
the customer.  The Company records  revenues from completion  services when
the outfitted  aircraft is delivered to the customer.  The Company plans to
deliver  approximately  60 green  aircraft  in fiscal 1998 and 65 in fiscal
1999,  and  completions  are expected to nearly  double in 1998 compared to
1997. Risks  associated with green  deliveries and completions  include the
following:

          Purchased  Materials  and  Equipment.  Approximately  70%  of the
     production  costs of both the  Gulfstream  IV-SP and the  Gulfstream V
     consist of materials and equipment purchased from other manufacturers.
     While the Company's  production  activities have never been materially
     affected by its inability to obtain components,  and while the Company
     maintains  business  interruption   insurance  in  the  event  that  a
     disruption  should occur,  the failure of the  Company's  suppliers to
     meet the Company's  performance  specifications,  quality standards or
     delivery  schedules  could  have  a  material  adverse  impact  on the
     Company's delivery schedule.

          Workforce.  The  Company's  ability  to meet its  production  and
     completion  schedules  depends on the  Company  meeting  its needs for
     skilled labor. Although the Company's ability to hire required skilled
     labor  has not to date  adversely  affected  its  ability  to meet its
     production  and completion  schedules,  there can be no assurance that
     this favorable  condition will continue.  In 1996, the Company entered
     into a  5-year  contract  with a  union  representing  certain  of its
     employees at its Oklahoma  Facility.  Although employee  relations are
     generally good, a work stoppage or other labor action could materially
     and adversely affect the Company's production schedule.

          Facilities.   Green  aircraft  are  assembled  at  one  facility.
     Detailed parts and  subassemblies  are  manufactured at two additional
     facilities. Completions are performed at five facilities. Although the
     Company maintains property and business  interruption  insurance,  any
     severe  property  damage  or  other  casualty  loss  at one  of  these
     facilities   could  materially  and  adversely  affect  the  Company's
     delivery schedule.

          Gulfstream  V  Efficiency.  The  Company  expects to become  more
     efficient  at  producing  and  completing  Gulfstream V aircraft as it
     gains more  experience  in this  aircraft  program.  If the Company is
     unable to achieve  anticipated  efficiencies,  its  delivery  schedule
     could be adversely impacted.

          Period-to-Period  Fluctuations.  Since the Company  relies on the
     sales of a  relatively  small  number of high unit  selling  price new
     aircraft to provide the  substantial  portion of its revenues,  even a
     small  decrease in the number of deliveries in any period could have a
     material  adverse  effect on the results of operation for that period.
     As a  result,  a  delay  or an  acceleration  in the  delivery  of new
     aircraft may affect the Company's revenues for a particular quarter or
     year  and may  make  quarter-to-quarter  or  year-to-year  comparisons
     difficult.

MARGIN IMPROVEMENTS

     The  Company  expects  gross  margins  (excluding   inventory  step-up
resulting from the K-C Aviation  acquisition and pre-owned aircraft,  which
are typically sold at break-even levels) to improve from 20% in 1997 to the
mid-20s  by  the  end of  1998.  Risks  associated  with  projected  margin
improvement include the following:

          Gulfstream V Learning Curve.  The Company expects  production and
     completion  costs to fall as the  Company  gains  more  experience  in
     producing and completing Gulfstream V aircraft.  Delays in anticipated
     cost reductions would adversely affect projected margin  improvements.
     If subsequent  improvement is not achieved as quickly or to the extent
     anticipated, the Company may be unable to achieve its margin targets.

          Cost of Materials.  Approximately  70% of the production costs of
     both the  Gulfstream  IV-SP and the  Gulfstream V consist of materials
     and equipment purchased from other manufacturers. Although the Company
     has in place revenue share and long-term supply arrangements that help
     protect  it  against   materials  price  increases,   if  the  Company
     experiences  price  pressure on materials,  margins could be adversely
     affected.

STABILITY OF BACKLOG

     At September 30, 1998, the Company had a backlog of $2.9 billion.  The
Company is currently  selling  outfitted  Gulfstream IV-SPs for delivery in
the first half of 2000 and  outfitted  Gulfstream  Vs for  delivery  in the
second  half of 2000.  Although  the  Company's  revenues  are,  therefore,
essentially  under  contract  for the  foreseeable  future,  the  following
factors could adversely affect the stability of the backlog:

          New  Orders.  The  Company's  principal  business  is the design,
     development,  manufacture and marketing of large and ultra-long  range
     business jet  aircraft.  Because of the high unit selling price of its
     aircraft  products and the  availability  of  commercial  airlines and
     charters  as  alternative  means of  business  travel,  a downturn  in
     general economic  conditions could result in a reduction in the orders
     received  by the  Company  for  its new and  pre-owned  aircraft.  The
     Company would not be able to rely on sales of other products to offset
     a reduction  in sales of its  aircraft.  If a potential  purchaser  is
     experiencing a business  downturn or is otherwise seeking to limit its
     capital expenditures,  the high unit selling price of a new Gulfstream
     aircraft  could  result  in  the  potential  purchaser  deferring  its
     purchase  or  changing  its  operating  requirements  and  electing to
     purchase a  competitor's  lower priced  aircraft.  In  addition,  if a
     significant number of customers resell their purchase  contracts,  the
     Company's  new  order  intake  could  be  adversely  affected.  If the
     Company's new order intake rate varies,  the Company could be required
     to adjust its production rate.

          Production   Delays.   While  the  Company   generally   receives
     non-refundable deposits in connection with each order, an order may be
     canceled (and the deposit  returned)  under certain  conditions if the
     delivery of a  Gulfstream  V aircraft is delayed  more than six months
     after a customer's  scheduled  delivery date. An extended delay in the
     production or completion process could cause an increase in the number
     of cancellations of orders,  which could have an adverse effect on the
     Company's results of operations.

          Business and Economic  Conditions.  Although 75% of the Company's
     backlog consists of North American customers and 43% of North American
     customers  are Fortune 500  companies,  adverse  business and economic
     conditions  could  cause  customers  to  be  unable  or  unwilling  to
     consummate the purchase of an aircraft and could, therefore,  increase
     the number of cancellations experienced by the Company.

YEAR 2000 READINESS

     As part of the  Company's  initiatives,  begun  in 1996,  to  increase
production  rates and co-produce the Gulfstream IV-SP and Gulfstream V, the
Company has, and continues  to,  upgrade and replace  business  systems and
facility  infrastructure.  These  initiatives  help to reduce the potential
impact  of the  Year  2000  date  issue  on the  Company's  operations.  In
addition,  the Company has implemented a Year 2000 Compliance Plan designed
to ensure that all other  hardware,  software,  systems,  and products with
microprocessors  relevant  to the  Company's  business  are  not  adversely
affected by the Year 2000 date issue.

     The Company does not believe that the implementation of this Year 2000
Compliance  Plan will have a  material  effect  on the  Company's  business
operations, financial condition, liquidity or capital resources. Management
of the Company believes it has an effective program in place to address the
Year  2000  issue in a  timely  manner.  As a  component  of the Year  2000
Compliance  Plan, the Company is developing  contingency  plans to mitigate
the effects of potential  problems  experienced by it or its key vendors or
suppliers in the timely  implementation  of its Year 2000 Compliance  Plan.
Nevertheless,  since it is not possible to anticipate all future  outcomes,
especially when third parties are involved, there could be circumstances in
which the Company's operations would be adversely affected.

SAFETY RECORD

     The Company  believes that its  reputation  and the  exemplary  safety
record of its aircraft are important  selling  points for new and pre-owned
Gulfstream  aircraft.  However,  if one or a number of catastrophic  events
were to occur with the Gulfstream fleet,  Gulfstream's reputation and sales
of Gulfstream aircraft could be adversely affected.

PRE-OWNED AIRCRAFT MARKET

     In many cases,  the Company  has agreed to accept,  at the  customer's
option, the customer's  pre-owned aircraft as a trade-in in connection with
the purchase of a Gulfstream  IV-SP or  Gulfstream  V. Based on the current
market for pre-owned  aircraft,  the Company expects to continue to be able
to resell pre-owned  aircraft taken in trade, and does not expect to suffer
a loss with respect to these trade-ins and resales.  However,  an increased
level of pre-owned aircraft or changes in the market for pre-owned aircraft
may increase the  Company's  inventory  costs and may result in the Company
receiving lower prices for its pre-owned aircraft.

COMPETITION

     The  market  for  large  cabin   business   jet   aircraft  is  highly
competitive.  The Gulfstream IV-SP competes in the large cabin business jet
aircraft  market  segment,  principally  with  Dassault  Aviation  S.A. and
Bombardier Inc. ("Bombardier"). The Gulfstream V competes in the ultra-long
range  business  jet aircraft  market  segment,  primarily  with the Global
Express,  which is being marketed by Canadair,  a subsidiary of Bombardier,
and which will not be  certified by the FAA until more than 21 months after
the  initial  delivery  of  the  Gulfstream  V.  The  Boeing  Company,   in
partnership with General Electric Co., is marketing a version of the Boeing
737 into the ultra-long range business jet aircraft market segment.  Boeing
has indicated that it expects this aircraft to be available for delivery in
the fourth  quarter of 1998. In June 1997,  Airbus  Industrie  announced it
would market a version of the Airbus A319 into this market segment as well.
Airbus has indicated  that it expects the aircraft to be available in early
1999.  The  Company's  competitors  may have  access to  greater  resources
(including, in certain cases, governmental subsidies) than are available to
the Company.

     The Company's  ability to compete  successfully  in the large business
jet and ultra-long  range business jet aircraft  markets over the long term
requires continued technological and performance enhancements to Gulfstream
aircraft. No assurance can be given that the Company's competitors will not
be able to produce aircraft  capable of performance  comparable or superior
to Gulfstream aircraft in the future.  Increased price-based competition by
the  Company's  competitors  could  pressure the Company to also reduce its
prices.  Price reductions could have a significant  impact on the Company's
margins.  In addition,  if a significant number of customers were to cancel
orders  for the  Company's  aircraft  in order to  purchase  a  competitive
product, there could be a material adverse effect on the Company's backlog.

PENDING TAX AUDIT

     The Company is involved in tax audits by the Internal  Revenue Service
covering the years 1990 through 1994. The revenue  agent's  reports include
several  proposed  adjustments   involving  the  deductibility  of  certain
compensation expense,  items relating to the initial  capitalization of the
Company,  the allocation of the original purchase price for the acquisition
by the Company of the  Gulfstream  business,  including  the  treatment  of
advance  payments  with  respect to and the cost of  aircraft  that were in
backlog at the time of the  acquisition,  and the  amortization  of amounts
allocated to  intangible  assets.  The Company  believes  that the ultimate
resolution of these issues will not have a material  adverse  effect on its
financial  statements because the financial statements already reflect what
the Company currently believes is the expected loss of benefit arising from
the  resolution  of these  issues.  However,  because the  revenue  agent's
reports are proposing  adjustments in amounts  materially in excess of what
the Company has  reflected in its financial  statements  and because it may
take several years to resolve the disputed matters,  the ultimate extent of
the Company's  expected loss of benefit and liability with respect to these
matters  cannot be predicted  with  certainty and no assurance can be given
that the Company's  financial position or results of operations will not be
adversely affected.

LEVERAGE AND DEBT SERVICE

     The degree to which the  Company is  leveraged  at a  particular  time
could have important consequences to the Company,  including the following:
(i) the Company's ability to obtain additional  financing in the future for
working capital, capital expenditures,  product development,  acquisitions,
general  corporate  purposes  or other  purposes  may be  impaired;  (ii) a
portion of the Company's and its  subsidiaries'  cash flow from  operations
must be  dedicated  to the payment of the  principal of and interest on its
indebtedness;   (iii)  the  Company's  credit  agreement  contains  certain
restrictive  financial and operating  covenants,  including,  among others,
requirements  that the Company satisfy  certain  financial  ratios;  (iv) a
significant portion of Gulfstream's borrowings will be at floating rates of
interest,  causing  Gulfstream  to be  vulnerable  to increases in interest
rates;  (v) the Company's degree of leverage may make it more vulnerable in
a downturn in general economic conditions; and (vi) the Company's financial
position may limit its  flexibility in responding to changing  business and
economic conditions.
