                        NORTHWEST AIRLINES CORPORATION
- -------------------------------------------------------------------------------
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
- -------------------------------------------------------------------------------

1.   The condensed consolidated financial statements of Northwest Airlines
     Corporation ("NWA Corp." or the "Company") included herein have been
     prepared pursuant to the rules and regulations of the Securities and
     Exchange Commission ("SEC").  Certain information and footnote disclosures
     normally included in annual financial statements prepared in accordance
     with generally accepted accounting principles have been condensed or
     omitted as permitted by such rules and regulations. These financial
     statements and related notes should be read in conjunction with the
     financial statements and notes thereto included in the Company's audited
     consolidated financial statements for the year ended December 31, 1995
     contained in the Company's Annual Report on Form 10-K for 1995 (the "Annual
     Report").

     In the opinion of management, the interim financial statements reflect
     adjustments, consisting of normal recurring accruals, which are necessary
     to present fairly the Company's financial position, results of operations
     and cash flows for the periods indicated.  

2.   The Company's accounting and reporting policies are summarized in Note A of
     the Notes to Consolidated Financial Statements in the Annual Report.

     Effective with the first quarter 1996 financial reporting, the Company
     reports gains (losses) relating to the disposition of assets as operating
     expenses instead of in other income (expense) in accordance with Statement
     of Financial Accounting Standards No. 121, "Accounting for the Impairment
     of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of."  This
     change had no impact on net income, and gains (losses) on the disposition
     of assets are excluded from unit cost calculations.

3.   The income tax expense is based on estimated annual effective tax rates
     which differ from the federal statutory rate of 35% primarily due to state
     income taxes and certain nondeductible expenses.

4.   As discussed under "Management's Discussion and Analysis of Financial
     Condition and Results of Operations--Liquidity and Capital Resources", in
     February 1996 the Company entered into agreements providing for the
     purchase and financing of 20 Airbus A320 aircraft as well as the
     rescheduling of certain Airbus A330 aircraft deliveries. The Company has
     substitution rights with respect to the A330 aircraft.  This transaction
     also included the rescheduling of existing debt to beyond 2000 at lower
     interest rates.

5.   At September 30, 1996, the Company had no revolving credit facility
     borrowings outstanding under its unsecured Credit Agreement.  The $237.2
     million in borrowing capacity under such facility along with $961.8 million
     of cash, cash equivalents and unrestricted short-term investments provided
     the Company with $1.20 billion of available liquidity at September 30,
     1996.  In May 1996, the Company used $50 million of existing funds to
     prepay a portion of its floating rate term loan under the Credit Agreement
     and increased the revolving credit facility by the same amount.  In July
     1996, the Company used $125 million of existing funds to prepay an
     additional portion of this floating rate term loan.  

     In October 1996, the Credit Agreement was amended (i) to increase the
     floating rate term loan thereunder from $125 million to $150 million and
     extend its final maturity to 2002 and (ii) to increase the revolving credit
     facility from $250 million to $500 million and extend the expiration date
     of the facility to October 2001.  Scheduled maturities of long-term debt
     subsequent to September 30, 1996, adjusted to give effect to the amended
     Credit Agreement and excluding short-term notes payable, are $14.1 million
     in 1996, $68.7 million in 1997, $89.0 million in 1998, $220.2 million in
     1999 and $110.5 million in 2000.

                                      6

6.   In June 1996, $524.5 million of equipment trust pass through certificates
     were issued in connection with the refinancing of the lessors' bridge
     indebtedness associated with 11 leveraged operating leases relating to two
     B747 aircraft and nine B757 aircraft leased to the Company.  The proceeds
     related to the issuance of the equipment trust pass through certificates
     were used to repay such indebtedness of the lessors.

7.   In June 1996, the Company and KLM Royal Dutch Airlines ("KLM") entered into
     an agreement pursuant to which the Company agreed to acquire 3,691.2 shares
     of its Series A Preferred Stock and 2,962.8 shares of its Series B
     Preferred Stock held by KLM.  On July 1, 1996, the Series A shares were
     acquired by the Company in exchange for a $227 million unsecured promissory
     note payable December 30, 1996.  On July 26, 1996, the Series B shares were
     acquired by the Company in exchange for a $152 million unsecured promissory
     note payable June 13, 1997.  The Company reported a one-time increase to
     net income applicable to common stockholders of $74.5 million in the third
     quarter of 1996 and annual earnings-per-share will benefit by approximately
     $0.12 until the date on which the stock would have become subject to
     mandatory redemption.

     data is presented for Northwest Airlines, Inc.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

Substantially all of the Company's results of operations are attributable to
Northwest Airlines, Inc. ("Northwest") and the following discussion pertains
primarily to Northwest.  The Company's results of operations for interim periods
are not necessarily indicative of such results for an entire year due to
seasonal factors as well as competitive and general economic conditions. 
 
For the quarter ended September 30, 1996, the Company reported unaudited net
income of $253.9 million and operating income of $469.4 million.  Primary
earnings per common share were $3.15 ($2.86 fully diluted), an improvement of
$.88  ($.75 fully diluted).  The earnings per share improvement includes the
effect of a $74.5 million ($.66 per share for fully diluted earnings per share)
increase in net income applicable to common stockholders resulting from the July
1996 acquisition of the Company's preferred stock previously held by KLM.  Cash,
cash equivalents and unrestricted short-term investments were $961.8 million at
September 30, 1996.  Additionally, at September 30, 1996, the Company had
available $237.2 million in borrowing capacity under its revolving credit
facility providing total available liquidity of $1.20 billion.  During the nine
months ended September 30, 1996, the Company reduced its long-term debt by
$306.7 million, including $205 million of payments prior to maturity.

RESULTS OF OPERATIONS--THREE MONTHS ENDED SEPTEMBER 30, 1996 AND 1995

Operating income increased $44.2 million to $469.4 million.  The improvement was
largely due to a $183.8 million increase in passenger revenues and a $73.8
million decrease in stock-based employee compensation which were offset by an
increase in aircraft fuel and related taxes of $89.6 million, an increase in
salaries, wages and benefits of $48.4 million, and an increase in aircraft 
maintenance of $34.9 million.  Operating margin increased 0.6 points from 16.6%
to 17.2%.

OPERATING REVENUES.  Operating revenues were $2.74 billion, an improvement of
$174.2 million (6.8%).  System passenger revenues (which represented 88.5% of
total operating revenues) increased $183.8 million (8.2%).  The increase was
primarily attributable to an 8.5% increase in scheduled service ASMs.

                                      8

<PAGE>

Domestic passenger revenue increased $148.3 million (10.8%) to $1.52 billion. 
The 7.3% increase in scheduled service ASMs resulting primarily from the
addition of DC9-30, DC10-30 and B757 aircraft, which allowed the Company to
increase frequencies to 23 cities and enter eight new markets, and a 3.9%
increase in yield were the primary causes of the improved performance. 
Passenger revenues were favorably impacted by the lapsed federal taxes on
airline tickets and international departures.  See "Other Information - U.S.
TRANSPORTATION TAX".  Pacific passenger revenue decreased by $11.5 million
(1.6%) to $687.2 million despite an 8.7% increase in scheduled service ASMs
resulting primarily from new service to Beijing, China and additional trans-
Pacific frequencies due to higher utilization of existing aircraft.  The impact
of the increase in scheduled service ASMs was offset by a 9.9% decrease in
yield.  The Pacific yield decrease is attributable to a weaker Japanese yen. 
The average yen per U.S. dollar exchange rate for the three months ended
September 30, 1996 and 1995 was 109 and 90, respectively.  Transatlantic
passenger revenue increased $46.9 million (27.6%) to $217.1 million due to an
8.6% increase in yield and a 16.3% increase in scheduled service ASMs primarily
as a result of the addition of Amsterdam service from Detroit, Washington D.C.
and New York City.

OPERATING EXPENSES.  Operating expenses increased $130.0 million.  While
operating capacity increased 8.5% to 25.2 billion total service ASMs, operating
expense per total service ASM decreased 1.3%.  Excluding stock-based
compensation in both periods, operating expense per ASM increased 2.9% to 8.24
cents largely related to higher fuel prices and increased maintenance costs. 
Salaries, wages and benefits expense increased $48.4 million (7.9%) due in part
to an increase in average full-time equivalent employees of 4.7% which was
attributable to the increased flying of 8.5% and increased traffic of 6.5%. 
Additionally, included in the increased salaries, wages and benefits expense is
a $12.9 million unfavorable impact of pension expense due to a lower pension
discount rate.  Non-cash stock-based employee compensation expense is a function
of shares earned by employees and the period-ending common stock price.  The
stock-based compensation expense decreased to $59.2 million from $133.0 million
for the third quarter of 1995.  The period-ending common stock prices were
$35.375 per share at September 30, 1996 and $42.50 at September 30, 1995.  The
expense for the third quarter includes the revaluation of the value of stock
earned by employees in the first and second quarters. Aircraft fuel and related
taxes increased $89.6 million (31.9%).  A 22.0% increase in average fuel cost
per gallon and an excise tax increase which was effective October 1995 caused
$73.8 million of the increase with the balance attributable to increased flying.
Aircraft maintenance materials and repairs increased $34.9 million (31.4%) due
to a number of factors including the timing of maintenance activities, increased
flying and higher engine overhaul costs.  Other expenses grew $27.0 million
(5.9%) largely due to timing of advertising and promotional expenses, increased
selling and marketing fees, communication expenses and claims, somewhat offset
by decreased passenger charter expenses.

OTHER INCOME AND EXPENSE.  Interest expense-net decreased $32.6 million (33.1%)
primarily due to the retirement of debt prior to scheduled maturity and the
restructuring of the Company's financing arrangement related to certain property
in Japan described in Notes C and E to Consolidated Financial Statements in the
Annual Report.  The foreign currency gain for the three months ended September
30, 1996 was attributable to balance sheet remeasurement of foreign currency-
denominated assets and liabilities.  The foreign currency gain for the three
months ended September 30, 1995 was attributable to a $8.7 million gain on
remeasurement of foreign currency-denominated assets and liabilities and a $19.1
million gain on Japanese yen collar option contracts.  Other expense for the
three months ended September 30, 1996 includes a payment of $10.9 million made
pursuant to the proposed travel agency settlement agreement - see "LEGAL
PROCEEDINGS". 

RESULTS OF OPERATIONS--NINE MONTHS ENDED SEPTEMBER 30, 1996 AND 1995

Operating income increased $156.3 million (19.0%) to $978.5 million.  The
improvement was largely due to a $700.5  million increase in passenger revenues
offset by an increase in operating expenses of $500.7 million.  Operating
revenue per total ASM increased 3.1% from 9.69 cents to 9.99 cents. Operating
margin increased 1.1 points from 11.9% to 13.0%.

OPERATING REVENUES.  Operating revenues were $7.54 billion, an improvement of
$657.0 million (9.5%).  System passenger revenues (which represented 87.3% of
total operating revenues) increased $700.5 million (11.9%).  The increase was
attributable to an 8.2% increase in scheduled service ASMs, a 2.2% increase (1.6
points) in passenger load factor and a 1.2% increase in system yield. 

                                      9

<PAGE>

Domestic passenger revenue increased $500.0 million (13.0%) to $4.33 billion. 
The increase was due to a 6.6% increase in scheduled service ASMs and a 5.3%
increase in yield.  Revenues were also favorably impacted by the lapsed federal
taxes.  See "Other Information - U.S. TRANSPORTATION TAX".  Pacific passenger
revenue increased by $84.3 million (5.1%) to $1.75 billion due to a 9.1%
increase in scheduled service ASMs and a 4.5% increase (3.4 points) in passenger
load factor, offset somewhat by a 7.7% decrease in yield.  The Pacific yield
decrease is attributable to a weaker Japanese yen.  Transatlantic passenger
revenue increased $116.2 million (29.9%) to $505.2 million due primarily to a
16.1% increase in scheduled service ASMs and a 9.1% increase in yield.

OPERATING EXPENSES.  Operating expenses increased $500.7 million.  While
operating capacity increased 8.2% to 70.8 billion total service ASMs, operating
expense per total service ASM increased 1.3%.  Operating expense per total ASM
excluding stock-based compensation increased 2.6% to 8.31 cents largely related
to higher fuel prices and increased maintenance costs.  Salaries, wages and
benefits expense increased $162.8 million (9.1%) due in part to an increase in
average full-time equivalent employees of 4.7% which was attributable to the
increased flying of 8.2% and increased traffic of 7.4%.  Additionally, included
in the increased salaries, wages and benefits expense was a $53.6 million
unfavorable impact of pension expense due to a lower pension discount rate. 
Non-cash stock-based employee compensation expense was $244.3 million, compared
to $298.8 million, a decrease of $54.5 million (18.2%).  Aircraft fuel and
related taxes increased 27.1% from $792.4 million to $1.01 billion.  A 17.0%
increase in average fuel cost per gallon and an excise tax increase which was
effective October 1995 caused $168.8 million of the increase with the balance
attributable to increased flying.  Aircraft maintenance materials and repairs
increased $78.9 million (25.3%) due to a number of factors including the timing
of maintenance activities, increased flying activity, higher engine overhaul
costs and the impact of a favorable vendor settlement in 1995.  Other expenses
grew $82.2 million (6.1%) largely due to increased costs for outside services,
advertising and promotional expenses, communication expense, selling and
marketing fees, personnel expense and supplies expense.

OTHER INCOME AND EXPENSE.  Interest expense-net decreased $101.7 million (33.7%)
primarily due to the retirement of debt prior to scheduled maturity and the
restructuring of the Company's financing arrangement related to certain property
in Japan.  The foreign currency gain for the nine months ended September 30,
1996 was attributable to balance sheet remeasurement of foreign currency-
denominated assets and liabilities.  Foreign currency loss for the nine months
ended September 30, 1995 was attributable to a $26.4 million loss on balance
sheet remeasurement of foreign currency-denominated assets and liabilities and a
$10.4 million charge related to Japanese yen collar option contracts.  

LIQUIDITY AND CAPITAL RESOURCES

Net cash provided by operating activities for the nine months ended September
30, 1996 was $1.21 billion, a $103.3 million increase compared with the nine
months ended September 30, 1995.  Investing activities in 1996 pertain primarily
to property and equipment additions.  The acquisition of 17 DC-9 aircraft, 13
B757 aircraft, seven B727 aircraft, three DC-10 aircraft, two B747 aircraft, one
MD-80 aircraft and the refurbishment of DC-9 aircraft account for the majority
of the $1.06 billion of property additions in 1996.  Investing activities in
1995 include primarily aircraft capital expenditures and net proceeds from
short-term investment transactions.  Financing activities in 1996 pertain
primarily to the sale and leaseback of seven of the thirteen B757-200 aircraft
and the payment of debt and capital lease obligations including the prepayments
of $175 million of the floating rate term loan and $30 million of floating rate
term certificates.  Financing activities in 1995 pertain primarily to the
payments of long-term debt and capital lease obligations.  

In February 1996, the Company entered into agreements providing for the purchase
and financing of 20 Airbus A320 aircraft (thirteen in 1998 and seven in 1999) as
well as the rescheduling of 16 Airbus A330 aircraft deliveries to eight in each
of 2004 and 2005.  The Company has substitution rights with respect to the A330
aircraft.  Additionally, this transaction included the rescheduling of $456.9
million of existing debt to beyond 2000 at lower interest rates.  In September
1996, the Company exercised its right to delay delivery from 1998 to 2002 of two
Boeing 747-400 aircraft and is scheduled to take delivery of two 747-400
aircraft in 1999 with an option to defer delivery until 2003.

                                     10

<PAGE>

In October 1996, the Company amended an existing credit facility pursuant to
which the lenders have agreed to provide up to $240 million of interim debt
financing for up to six B757 aircraft delivered in 1996 and/or the Airbus A320
aircraft to be delivered in 1998 and 1999.  This amended facility expires in
October 1999 and loans thereunder have a final maturity not later than October
2016.

See also Note 7 of Notes to Condensed Consolidated Financial Statements for a
discussion of the purchase by the Company of certain shares of the Company's
Series A and Series B Preferred Stock held by KLM.

OTHER INFORMATION 

LABOR AGREEMENTS.  Pursuant to amended labor agreements which provide for wage
and other cost reductions aggregating approximately $886 million over a 39 month
period (the "Wage Savings Period") which commenced August 1993, the Company has
agreed to issue common and preferred stock to employees.  Management's
Discussion and Analysis of Financial Condition and Results of Operations and
Note C of the Notes to Consolidated Financial Statements in the Annual Report
contain additional discussion of the labor cost savings agreements, stock to be
issued to employees and the related accounting treatment.  The fifth installment
of shares issuable to the employee trusts, consisting of 2,555,757 shares of
Series C Preferred Stock, 4,215,409 shares of Class A Common Stock and 536,880
shares of Class B Common Stock, was made on March 1, 1996.

The Wage Savings Period ended on July 31, 1996 for flight attendants, September
30, 1996 for mechanics, ground personnel and management and October 30, 1996 for
pilots.  At the end of the Wage Savings Period, salaries and wages, which are
subject to amendable contracts, are estimated to increase by approximately $280
million on an annualized basis and the financial reporting recognition of stock-
based employee compensation expense will cease.

FOREIGN CURRENCY. The Company's yen-denominated revenues exceed its yen-
denominated expenses by approximately 60 billion yen per year and its yen-
denominated liabilities exceed its yen-denominated assets.  In general, as the
Japanese yen strengthens (weakens), the Company's operating income is favorably
(unfavorably) impacted and a nonoperating foreign currency loss (gain) is
recognized due to the remeasurement of net yen liabilities. In recent periods
the yen has weakened as the yen exchange rate has changed from 100 yen to $1 at
September 30, 1995 to 103 yen to $1 at December 31, 1995 to 111 yen to $1 at
September 30, 1996.

U.S. TRANSPORTATION TAX.  The U.S. 10% passenger ticket tax applicable to
domestic travel, the 6.25% domestic cargo waybill tax and the $6 per passenger
international departure tax expired on December 31, 1995.  Consequently, the
Company ceased collecting these taxes on January 1, 1996.  Legislation
reauthorizing these taxes for travel through December 31, 1996 went into effect
for tickets sold subsequent to August 27, 1996.  The impact on future operating
income of such reinstatement is uncertain.

USE OF FINANCIAL INSTRUMENTS.  In order to mitigate its exposure to foreign
exchange rate fluctuations, from time to time the Company uses a collar option
strategy to hedge its anticipated yen-denominated net cash flows.  At September
30, 1996, the Company had hedged, using collar options approximately 80% of its
remaining 1996 anticipated yen-denominated net cash inflows (14.4 billion yen)
and has no material unrealized gains or losses.  In the ordinary course of
business, the Company manages the price risk of fuel costs utilizing both
regulated exchange traded futures contracts and fuel swap agreements.  Gains or
losses on hedge contracts are deferred until the related fuel inventory is
expensed.  As of September 30, 1996, the Company had no material hedges for
future fuel requirements.

FULLY DISTRIBUTED EARNINGS PER SHARE. The effect of the accounting for stock-
based compensation on the Company's operating results and earnings per share may
make it difficult to compare its earnings with other companies.  Accordingly,
management believes that a "fully distributed" earnings per share calculation,
which excludes stock-based compensation and the unfavorable proforma impact of
the expiration of the labor cost savings and includes all the shares to be
issued to its employees, provides an appropriate supplemental measurement of the
Company's performance.  On a fully distributed basis, the Company's net earnings
applicable to common stockholders would have been $359.8 million ($3.15 per
share) and $706.2 million ($6.19 per share) for the three and nine months ended
September 30, 1996, respectively, an improvement of $58.1 million ($0.51 per
share) and $158.8 million ($1.39 per share) over the corresponding periods in
1995.  The fully distributed earnings per share for the three and nine months
ended September 30, 1996 includes the effect of a $.65 per share one-time
increase resulting from the July 1996 acquisition of the Company's preferred
stock previously held by KLM.  The fully distributed earnings per share for the
nine months ended September 30, 1995 includes the effect of a $.52 per share
increase resulting from the January 1995 exchange of the Company's preferred
stock for common stock.

MESABA REGIONAL JET AGREEMENT.  In October 1996, the Company entered into an
agreement with Mesaba Aviation, Inc. ("Mesaba"), under which Mesaba will operate
12 Avro Regional Jet aircraft as a new Northwest regional jet service.  The
Company will acquire or lease the regional jets from Aero International
(Regional) or an affiliate for sublease to Mesaba.  The new aircraft are
scheduled for delivery beginning in April 1997 at the rate of one per month. 

DETROIT MIDFIELD TERMINAL.  In October 1996, the Company and Wayne County,
Michigan (the "County") entered into an agreement pursuant to which, subject to
the satisfaction of certain conditions set forth in the agreement, the Company
will manage and supervise the design and construction of a $700 million midfield
terminal at Detroit Metropolitan Wayne County Airport.  The new midfield
terminal is scheduled to be completed in 2001 (subject to extensions of such
date under certain circumstances) and will be funded from federal and State of
Michigan grants and existing passenger facility charges and through the County's
issuance of airport bonds payable primarily from future passenger facility
charges.  The Company and the County have entered into agreements pursuant to
which the Company will lease space in the new terminal for a term of 30 years
from the date the terminal opens.

PART II.  OTHER INFORMATION

ITEM 1.   LEGAL PROCEEDINGS

Reference is made to Item 3, "Legal Proceedings" included in the Annual Report
and Part II, Item 1, "Legal Proceedings" included in the Company's Form 10-Q for
the quarter ended June 30, 1996.  

IN RE:  TRAVEL AGENCY COMMISSION ANTITRUST LITIGATION (U.S.D.C. District of
Minnesota, Multi-District Litigation Docket No. 1058).  On September 3, 1996, an
agreement in principle to settle the antitrust class litigation between a class
of travel agency plaintiffs and American Airlines, Inc., Delta Airlines, Inc.,
United Airlines, Inc. and the Company was reached.  Under the settlement
agreement, the Company agreed to pay $10.9 million of the $72 million aggregate
settlement payment to be made by the four airlines.  (Separate settlement
agreements were reached by the plaintiffs with Continental Airlines, Inc., USAir
Inc. and Trans World Airlines, Inc.  The aggregate amount of all settlement
payments is approximately $86 million.)  In agreeing to settle the case, the
Company vigorously denied any wrongdoing and agreed to settle the litigation
solely to avoid the uncertainty and expense and diversion of management time and
effort associated with a protracted trial.  On September 9, 1996, the Court
preliminarily approved the settlement agreement and scheduled a hearing on final
approval of the settlement for November 15, 1996.

In the ordinary course of its business the Company is party to various other
legal actions which the Company believes are incidental to the operation of its
business.  Although the ultimate outcome of these other matters (including those
described in the Annual Report) cannot be predicted with certainty and could
have a material adverse effect on the Company's consolidated financial
condition, liquidity and operating results if resolved unfavorably, the Company
believes that the outcome of these actions will not have any such material
adverse effect.

existing gates on Concourse B.  In the event that, and for so long as, the 
USAir gates on Concourse B are not available or cannot accommodate USAir's

Lessee will make necessary and reasonable arrangements to accommodate USAir 
at gates which it has under lease with Lessor so long as USAir agrees to 
reasonably cooperate with Lessee in the use of such gates.

     Rentals for space vacated by Lessee on Concourse A will terminate upon 
the date the space is vacated.  Lessee shall not be responsible for lost 
Airport revenues or Airport expenses due to the relocation.  Lessor shall be

B.   ACTIVITY FEES AND CAPITAL EXPENDITURES:

     1.   ACTIVITY FEES:  All rentals, fees and charges for the use of the
          premises, facilities, rights, licenses, services and privileges
          granted hereunder, except those for which rentals, fees or charges are
          otherwise specifically provided herein, shall be combined in and

                                     - 35 -

<PAGE>

          (a)  the Revenue Requirement, as below defined, for such Fiscal Year,

               aircraft, in units of one thousand pounds, of all Signatory
               Airlines, for such Fiscal Year.

          The "Revenue Requirement" for any Fiscal Year as used herein shall
     mean that amount of revenue required to produce total net Airport revenue
     equal to the following amount:

          (1)  direct and indirect expenses of airport maintenance, operation
               and administration for such fiscal year; plus

          (2)  (a)  one hundred twenty-five percent (125%) of the amount of
               principal and interest due (net of any capitalized interest) for
               such Fiscal Year on all then outstanding Airport Revenue Bonds,
               less (b) any amounts on deposit in the Revenue Fund at the
               beginning of such Fiscal Year representing so-called "coverage"
               funds collected for so-called "rolling coverage" pursuant to any
               bond ordinance under which Bonds were issued that requires such
               rolling coverage; plus

          (3)  deposits into the Bond Reserve Account, the Operation and
               Maintenance Reserve Fund and the Renewal and Replacement Fund
               required for such fiscal year pursuant to the provisions of the
               Bond Ordinance; plus

          (4)  commencing in Fiscal Year 2001, an amount equal to $5 million
               (which amount shall be escalated each Fiscal Year beginning in

                                     - 36 -

<PAGE>

               Fiscal Year 2002 to reflect percentage increases in the Producer
               Price Index during the most recently ended 12-month period for
               which such index is available) minus the amount, if any,
               deposited for such Fiscal Year into the ACE Account; plus

          (5)  commencing in the Fiscal Year in which no Airport Revenue Bonds
               are subject to Paid-in Coverage (as defined below), $350,000;
               minus

          (6)  all other Airport revenues (including Exclusive Area and Common
               Area rentals and all concession and parking revenues) received
               [or receivable if the Lessor is on an accrual accounting basis]
               during such Fiscal Year (excepting Special Facility Bond
               Revenues).

          The unit thus arrived at shall be the Activity Fee rate per thousand
     pounds of Approved Maximum Landing Weight payable by Lessee to Lessor for
     such of Lessee's aircraft, or aircraft of its subsidiary, as have landed at
     the Airport during the Fiscal Year for which such calculation is made.

          The Activity Fee as herein established shall not be subject to further
     adjustment except by agreement of the parties hereto or as provided in
     Article III F.

          not incur expense for Airport operation, maintenance and
          administration in excess of the amounts reasonably and necessarily
          required therefor.

                                     - 37 -

<PAGE>

               (ii) that it shall operate the Airport in a manner so as to
          produce revenues from concessionaires, tenants, and users of a nature

          an airport.

               (iii)     That it will comply in all respects with the revenue
          retention requirement in Section 511(a)(12) of the Airport and Airway
          Improvement Act of 1982, as amended, now codified at 49 U.S.C. Section
          47107(b).  Commencing in Fiscal Year 1997, Lessor may include in O&M
          Expenses for each Fiscal Year administrative charges not in excess of
          $5 million, provided that the foregoing cap amount shall be escalated
          each Fiscal Year, commencing in Fiscal Year 1998, by multiplying the
          prior year's cap amount by a factor of one (1) plus the percentage
          increase, if any, in the index of average hourly earnings for
          production workers for manufacturing industries in the United States,
          as published by the United States Department of Labor, Bureau of Labor
          Statistics (or if this index is discontinued or otherwise becomes
          unavailable to the public, the most nearly comparable index of such
          average hourly earnings published by a recognized financial
          institution, financial publication or university) during the most
          recently ended 12-month period for which such index is available.  The
          annual administrative charges of $5 million shall pay for all services
          provided directly or indirectly by any department, division or agency
          of Lessor other than the Airport, or Central Communications to the
          extent operated by the Airport, in the nature of administration and
          legislative oversight, finance, budget, accounting, legal, payroll,
          purchasing, personnel, information processing, imaging, planning and
          development.  

                                     - 38 -

<PAGE>

          Administrative charges shall not include (A) optional contracted
          services by the Airport, such as landscaping, mowing, engineering
          (design, construction, inspection and project management) and 
          mechanical, electrical and plumbing trade services to be performed
          on Airport property, or (B) the payroll and fringe benefit costs for
          the employee positions described in Exhibit B; provided that any
          increase in such costs or the number of such positions above those
          shown on Exhibit B must be approved by a majority in number of the
          Signatory Airlines.

               (iv) That it will utilize competitive bidding procedures for the
          award of all maintenance and operation contracts and construction
          contracts for the Airport.

               (v)  That all senior appointed Airport officials shall have
          professional qualifications commensurate with the responsibilities of
          the jobs to be performed by such officials.

               (vi) That it will take all necessary actions to assure that the
          personnel of Lessor, whose wages and benefits are included in
          O&M Expenses, are actually performing work for the Airport as
          represented by such inclusion.

               (vii)     That it will operate Willow Run Airport only as a
          reliever airport for the Airport with no scheduled air carrier or
          public charter passenger service.

          Lessor and Lessee recognize that payment of the Activity Fee, as
     herein provided, together with other funds, will result in an annual
     surplus, because, among other things Ordinance 319 currently requires the
     collection by Lessor 

                                     - 39 -

<PAGE>

     of rates and charges necessary to produce in each Fiscal Year revenues 
     that include 125% of the principal and interest due in such year on 
     Airport Revenue Bonds (exclusive of capitalized interest thereon) (the 
     excess 25% required to be collected is herein referred to as "Paid-in 
     Coverage").  Lessor covenants to utilize such surplus only for the 
     retirement of Airport Revenue Bonds or as follows:

          (1)  Fifty percent (50%) of the amount attributable to the Paid-in
               Coverage, if any, on the Airport Revenue Bonds shall be deposited
               into the Airline Equity Account and allocated among the Airline
               Equity Subaccounts in accordance with the respective landed
               weights of each Signatory Airline for the applicable period;

          (2)  Three Hundred Fifty Thousand Dollars ($350,000) shall be
               deposited annually into the County Discretionary Fund;

          (3)  Fifty percent (50%) of the amount attributable to the Paid-in
               Coverage, if any, on the Airport Revenue Bonds (less $350,000
               annually) shall be deposited into the ACE Account; 

          (4)  Deposits shall be made into the Subordinate Bond Reserve Account,
               the Operation and Maintenance Reserve Fund and the Renewal and
               Replacement Fund pursuant to the provisions of the Ordinance 319,
               and into any other funds for similar purposes established
               pursuant to other ordinances under which Bonds are issued; 

          (5)  Amounts includible each Fiscal Year in the Revenue Requirement
               pursuant to item (4) of the definition thereof in Article III
               B.1. shall be deposited into the Airport Development Fund, to be
               established 

                                     - 40 -

               and held by Lessor for the purposes described in Article III
               B.2.(c)(4) below; and

     (b)  Lessor may issue Bonds to finance the costs (including all reasonable
     costs incidental to the issuance and sale of such bonds) of capital
     projects and may include the debt service (including, among other things,
     coverage requirements) on such Bonds in Lessee's fees hereunder only after
     first receiving approval of a Weighted Majority.

          Lessor may assign, in accordance with the Bond Ordinance and the terms
     of this Agreement, certain of its interests in and pledge certain revenues
     and receipts of the Airport as security for payment of the principal of,
     premium, if any, and interest on Bonds.  Except as set forth in the
     preceding sentence and except for residential property acquired by the
     Airport pursuant to the Airport's noise mitigation program, Lessor shall
     not pledge, sell, convey, mortgage, encumber, assign or otherwise transfer
     the Airport or any portion thereof during the term of this Agreement.

     (c)  The following limitations shall apply to expenditures from the below-
     described funds and accounts:

          (1)  EXPENDITURES TO BE MADE FROM THE COUNTY DISCRETIONARY FUND.

          Lessor may make expenditures from the County Discretionary Fund
          without approval by the air carriers for any lawful Airport-system
          purpose, except that expenditures for Willow Run Airport shall only be
          made if Lessor is in compliance with its covenant in Article III
          B.2.(a)(vii).

          (2)  CAPITAL EXPENDITURES TO BE MADE FROM THE ACE ACCOUNT.

                                     - 41 -

<PAGE>

          If Lessor proposes to make a capital expenditure from the ACE Account
          it shall be subject to the approval of the air carriers if such
          capital expenditure is greater than Fifty Thousand dollars ($50,000). 
          Such approval shall be deemed given unless within thirty (30) days
          after receipt of Lessor's proposal to make such expenditure Lessor is
          notified by a Majority-in-Interest of the air carriers, as hereinafter
          defined, that such expenditure is disapproved, such notification to
          contain specific reasons and grounds therefor.

          (3)  EXPENDITURES TO BE MADE FROM THE AIRLINE EQUITY SUBACCOUNTS.

          Each Signatory Airline may choose to use any amounts deposited into
          its Airline Equity Subaccount for any of the following purposes:

               (i)  as a direct credit against Activity Fees payable by it;

               (ii) for capital expenditures at the Airport; or

               (iii)     to service Special Facility Revenue Bond debt for
                         capital improvements at the Airport.

          (4)  EXPENDITURES TO BE MADE FROM AIRPORT DEVELOPMENT FUND.

          Lessor may make capital expenditures from the Airport Development Fund
          without approval by the air carriers for any lawful Airport-system
          related purpose, provided that Lessor shall not pledge the Airport
          Development Fund as security for any Bond or other debt of Lessor
          without approval of a Majority-in-Interest of the air carriers; and
          provided, further, that capital expenditures for Willow Run Airport
          shall only be made if Lessor is in compliance with its covenant in
          Article III B.2.(a)(vii).

                                     - 42 -

<PAGE>

     (d)  In order to permit Lessor to issue Bonds in compliance with applicable
     securities laws, Lessee agrees that upon the request of Lessor, Lessee
     shall provide to Lessor such information with respect to Lessee as Lessor
     deems reasonably necessary in order for Lessor to issue Bonds in compliance
     with the requirements of rule 15c-2(12) of the Securities and Exchange
     Commission.

C.   ADJUSTMENT OF RENTAL FEES:  For the purposes of this Agreement, and in
     order to compute any adjustment of rentals or fees due after the effective
     date hereof, the five-year period ending August 31, 1998, shall be regarded
     as the "first five-year period".

          The Rental Fees shall be subject to adjustment effective September 1,
     1998, and on September 1 of each successive five year period thereafter as
     follows:

          In fixing the Rental Fees for the second five-year period, if the
     average hourly earnings for production workers for manufacturing industries
     in the United States, as published by the Bureau of Labor Statistics of the
     United States Department of Labor (or if this index is no longer published,
     then the most nearly comparable published index of such average hourly
     earnings) on the first day of the month in which the second five-year
     period commences is greater than or less than such average hourly wage rate
     as published by the said Bureau of Statistics on September 1, 1993, then
     the percentage of increase over or decrease under the average hourly wage
     rate so published on the first day of September, 1993, shall be determined,
     and the Rental Fees adjusted by increasing  or decreasing the same, as the
     case may be, by the percentage so determined, and such adjusted Rental Fees
     shall apply during the said second 

                                     - 43 -

<PAGE>

     five-year period, provided only that no such adjustment shall increase or
     decrease such Rental Fees more than ten percent (10%) for the second
     five-year period compared with the Rental Fees applicable during the first
     five-year period.

          Each subsequent five-year adjustment at the beginning of each
     succeeding five-year period shall be computed in the same manner (and shall
     be subject to the same ten percent (10%) limitation of adjustment) except
     that the average hourly wage rates used upon such subsequent adjustments
     shall be those so published on the first day of the month in which such
     current five-year period commenced and first day of the month in which the
     next ensuing five-year period commences, which adjustments shall be based
     upon and applied to the Rental Fees for the preceding five year period.

D.   CHARGES FOR ELECTRICAL CURRENT:  Lessee shall pay to Lessor for Lessee's
     use and occupancy of Exclusive Areas and Common Areas under this agreement,
     a charge for electrical current furnished by Lessor to each such area, said
     charge to be computed as follows:

          (1)  In metered areas at a rate not exceeding that which Lessee would
               have to pay if it established the same demand and took the same
               quantity directly from the public utility supplying electrical
               current to the Airport, and

          (2)  In unmetered areas at a rate per square foot of occupied space as
               established by an electrical consultant appointed by Lessor.  In
               the event the parties hereto shall be unable to agree on the
               aforementioned charges, the controversy shall be subject to

                                     - 44 -

<PAGE>

               arbitration in the manner provided in Article XVII of this
               Agreement.

          (3)  In Common Areas the electrical current charge shall be shared
               with the other common users, 20% equally and 80% to be allocated
               on the basis of enplaned passengers.

E.   CHARGES FOR WATER AND SEWERAGE FACILITIES:  Lessor shall charge Lessee for
     water and sewerage facilities supplied Lessee's Exclusive Areas and the
     amount of such charge shall be subject to future agreement of the parties
     hereto.  In the event the parties hereto shall be unable to agree on such
     amount, the controversy shall be subject to arbitration in the manner
     provided in Article XVII of this Agreement.

F.   CONTINUING RENTAL OBLIGATION

     1.   Should any scheduled air carrier, including Lessee, having an
          agreement with Lessor substantially similar to the Basic Agreement or
          this Agreement, terminate its operations at the Airport by reason of
          the loss of its operating authority to serve the Detroit Metropolitan
          Area and exercise the right of cancellation provided for in such case
          in Article XV of the Basic Agreement or this Agreement, its continued
          obligation to pay to Lessor charges thereafter due under the Basic
          Agreement or this Agreement, including space rentals and Activity
          Fees, shall, subject to the provisions of the paragraph next
          following, thereupon terminate.  Payment of Rentals and Activity Fees
          thereafter required shall be the responsibility of such of the other
          aforesaid scheduled air carriers which 

                                     - 45 -

<PAGE>

          continue to provide air transportation service to the Detroit
          Metropolitan Area.

               Should (a) all such aforesaid air carriers lose their operating
          authority to serve the Detroit Metropolitan Area, or (b) should Lessor
          fail to maintain the necessary certifications required to permit
          scheduled air carrier operations at the Airport, and ALL of such air
          carriers exercise the right of cancellation provided for in either
          event in said Article XV, the obligation to pay such aforesaid charges
          shall terminate subject, however, to the following condition.  Upon
          such termination all such aforesaid carriers then operating at the
          Airport (including Lessee if such be the case) shall be obligated, to
          the extent hereinafter required, to pay annually, or in such
          installments as Lessor may require, an amount not in excess of three
          hundred percent (300%) of their respective annual rentals (calculated
          in the manner set forth in paragraph 2 below) payable at that time for
          terminal building space at the Airport (whether leased under the Basic
          Agreement, this Agreement or otherwise) for the purpose of providing
          funds to be applied to debt service (exclusive of any additional
          coverage) on the then outstanding issues of Bonds.  Payments required
          of such carriers shall be assessed against each of them in a uniform
          manner per square foot leased and shall be diminished pro rata to the
          extent that Airport revenues or capital funds are realized from other
          sources and are available for application to the debt service on the
          said bonds as provided for in Subparagraph 3 below.

                                     - 46 -

<PAGE>

     2.   For the purpose of calculating payments which such carriers may be
          obligated to make, Lessor shall first determine the average annual
          rental rate per square foot paid for such terminal building space by
          all such carriers by dividing their total annual rentals for such
          space by the total square footage of the space.  The square footage
          leased by each carrier shall then be multiplied by such average rate
          in order to obtain an annual rental of each such carrier for the
          purpose of establishing the three hundred percent (300%) maximum
          annual limitation.

     3.   In the event Lessor fails to maintain the necessary certifications
          required to permit scheduled air carrier operations at the Airport and
          thereafter operates the Airport for other purposes, any revenues
          earned as a result shall, after providing for necessary operating and
          maintenance expenses, be first applied each year to such debt service
          requirements before requiring payments by the carriers pursuant to
          paragraph (1) above.  In the foregoing circumstances and as long as
          any of the aforesaid Bonds are outstanding, Lessor shall use its best
          efforts to operate or lease the Airport properties so as to produce
          sufficient revenues to satisfy the requirements of the aforesaid
          Bonds.  If under such circumstances the Airport properties or portion
          thereof are sold by Lessor, the proceeds of such sale(s) shall first
          be used (or set aside) and be applied to current and future debt
          service requirements or to retire the aforesaid Bonds before requiring
          payments by the carriers pursuant to subparagraph 1 above.

G.   FACILITIES USE FEES - INTERNATIONAL TERMINAL BLDG. #520:

          For each use by Lessee of International Terminal Building 520, Lessee
     shall pay to Lessor a facilities use fee in accordance with the then
     current fee schedule adopted and promulgated by Lessor.  The amount of such
     facilities use fee shall be computed by Lessor in accordance with criteria
     established by the Detroit Airline Airport Affairs Committee, formerly
     known as the Detroit Airline Properties Committee, and approved by Lessor.

          Lessor covenants to use its best efforts to charge users of revenue
     producing improvements constructed with the proceeds of the above-described
     bonds an adequate and sufficient amount of rental and/or other charges to
     make such improvements self-sustaining and to cover a pro rata share of
     debt service, maintenance and operation and other such improvement
     expenses, it being the intent of the parties hereto to provide that those
     who benefit from the use of such improvements should bear the cost thereof
     to the extent possible.

          Lessor agrees to establish and maintain a schedule of rates and
     charges for all users of the Airport other than Lessee, except where
     precluded by contracts in effect on the date hereof, whereby the Activity
     Fee Schedule shall be at least equal for equivalent landed weight to those
     fees payable by Lessee hereunder.  Lessor also pledges its best efforts to
     attempt to secure the maximum amounts of grants-in-aid available under any
     federal, state or local program.

H.   PAYMENT OF RENTALS AND ACTIVITY FEES

     1.   INFORMATION ON LESSEE OPERATIONS:

          (a)  Not earlier than 120 days nor later than 90 days prior to the
          last day of each Fiscal Year, Lessee shall furnish Lessor with an
          estimate for the next ensuing Fiscal Year of (i) the total Approved
          Maximum Landing Weight of all aircraft to be landed at the Airport by
          Lessee, (ii) the total number of enplaned domestic and international
          passengers and deplaned domestic and international passengers of
          Lessee, and (iii) the total number of arriving and departing domestic
          and international flights of Lessee.

          (b)  Lessee shall, no later than the 20th day of each calendar month,
          transmit to Lessor a report, certified by Lessee, setting forth (i)
          the actual number of Lessee's enplaned passengers and deplaned
          passengers for the preceding calendar month, (ii) the actual aggregate
          Approved Maximum Landing Weight for all aircraft operated by Lessee
          and landed at the Airport during the preceding calendar month, and
          (iii) the actual number of Lessee's arriving and departing domestic
          and international flights for the preceding month.

     2.   PROJECTION OF RENTALS AND ACTIVITY FEES:  Not later than 60 days prior
to the end of each Fiscal Year, Lessor shall furnish Lessee with a projection
for the next ensuing Fiscal Year (the "Projection") of the rentals to be paid
hereunder, and the Activity Fee rate per thousand pounds of Approved Maximum
Landing Weight.  Such Projection will include Lessor's proposed Airport budget,
and shall set forth a calculation of the Activity Fee (including all sources of
revenue and all expenses) for the next ensuing Fiscal Year, together with other
information relevant thereto reasonably 

                                     - 49 -

<PAGE>

requested by Lessee.  Lessor shall give due consideration to any suggestions 
and comments made by Lessee with respect to the Projection.  The Projection, 
as revised by Lessor after considering Lessee's suggestions and comments, 
shall be the basis for computing Lessee's rentals and Activity Fees for the 
next ensuing Fiscal Year unless and until otherwise revised pursuant to 
paragraph 4 below.

     3.   PAYMENT OF RENTALS AND ACTIVITY FEES:

          (a)  Lessor shall, following the end of each calendar month, transmit
          to Lessee a statement of the rentals, fees and charges, other than the
          Activity Fees, incurred by Lessee during said month, and the same
          shall be paid by Lessee within fifteen days after receipt of such
          statement.

          (b)  Not later than the 20th day of each calendar month of each Fiscal
          Year, Lessee shall pay Lessor, without demand or invoice, an amount
          equal to Lessee's aggregate Activity Fees for the preceding calendar
          month, calculated by multiplying the total Approved Maximum Landing
          Weight for aircraft landed by Lessee at the Airport during the
          preceding calendar month by the Activity Fee rate for such Fiscal
          Year, computed in accordance with Article III.B.1., and based on the
          Projection, as such projection may have been revised pursuant to
          paragraph 4 below.

     4.   ADJUSTMENT OF RENTALS AND ACTIVITY FEES:  Not later than the 150th day
of each Fiscal Year, Lessor shall furnish Lessee with a revised Projection (the
"Mid-Year Projection"), which shall reflect the most recently available
information with regard to the amounts actually incurred or realized during such
Fiscal Year for Bond Debt Service, O&M Expenses, and the Revenue Requirement,
together with the most recently available information with regard to rentals and
Activity Fees actually received 

                                     - 50 -

<PAGE>

by Lessor.  Lessor shall give due consideration to any suggestions and 
comments made by Lessee with respect to the Mid-Year Projection.  If the 
Mid-Year Projection, as revised by Lessor after considering Lessor's 
suggestions and comments, indicates that aggregate payments of rentals and 
Activity Fees, at the then-existing rates would result in an overpayment or 
underpayment of the aggregate amount required to be generated by Lessor 
through rentals and Activity Fees, Lessor shall revise the Projection and 
adjust the rates set forth therein for such Fiscal Year to conform to the 
Mid-Year Projection.

     5.   PRELIMINARY ANNUAL SETTLEMENT AND FINAL AUDIT:

          (a)  Within 60 days after the end of each Fiscal Year, Lessor will
          furnish Lessee with a preliminary report, containing a preliminary
          calculation, based on actual data, in accordance with this Agreement,
          of Rentals and Activity Fees estimated to be chargeable to Lessee for
          the preceding Fiscal Year, and setting forth the amounts actually paid
          by Lessee for such period.  If such report indicates that the
          aggregate of such fees and charges actually paid by Lessee were
          greater than the aggregate amounts chargeable to Lessee, then within
          90 days after the end of such Fiscal Year Lessor shall refund 80% of
          any such estimated excess to Lessee.  If such report indicates that
          the aggregate of such fees and charges paid by Lessee were less than
          the amounts chargeable to Lessee, then within 90 days after the end of
          such Fiscal Year Lessee shall pay to Lessor 80% of the amount of any
          such estimated deficiency.  Interest shall accrue at

                                     - 51 -

<PAGE>

          a rate of 7% per annum, and be payable by Lessee in cash, on any 
          portion of any deficiency not paid by Lessee when due.  Interest 
          shall accrue at a rate of 7% per annum, and be payable by Lessor, 
          through a reduction in the amount of Lessor's administrative costs 
          includible in O&M Expenses for the then Fiscal Year pursuant to 
          Article III.B.2.(a)(iii), on any portion of any excess not refunded 
          to Lessee when due.

          (b)  By the 180th day of each Fiscal Year, Lessor shall furnish to
          Lessee a copy of an annual audit report prepared by a nationally
          recognized accounting firm, covering the operation of the Airport for
          the preceding Fiscal Year (the "Final Audit").  Lessor shall prepare a
          calculation, based on the Final Audit, in accordance with this
          Agreement, of all rentals and Activity Fees chargeable to Lessee for
          the preceding Fiscal Year, and setting forth the amounts actually paid
          by Lessee for such period, taking into account all payments and
          refunds pursuant to paragraph 5.(a) above.  If aggregate rentals and
          Activity Fees actually paid by Lessee were greater than the aggregate
          amount chargeable, then within 30 days after delivery of the Final
          Audit Lessor shall refund the amount of such overpayment to Lessee. 
          If aggregate rentals and Activity Fees actually paid by Lessee were
          less than the aggregate amount chargeable to Lessee, then within 30
          days after receipt of the Final Audit Lessee shall pay to Lessor the
          amount of any such deficiency.  The amount of Lessor's administrative
          costs includible in O&M Expenses for the then Fiscal Year shall be
          reduced by $50,000 for each month that delivery of the Final Audit to
          Lessee is delayed beyond the 180th day of such Fiscal Year.

          (c)  The payment by Lessee of any fees and charges hereunder and the
          acceptance by Lessor thereof for any Fiscal Year, shall not preclude
          either 

                                     - 52 -

<PAGE>

          Lessee or Lessor from questioning, within a period of one (1)
          year from the date of receipt by Lessee of the Final Audit for such
          Fiscal Year, the accuracy of any report or statement on the basis of
          which such payment was made, or preclude Lessor from making any claim
          against Lessee for any additional amount payable by Lessee, or
          preclude Lessee from making any claim against Lessor for the return of
          any excess amount paid by Lessee.

                                   ARTICLE IV

                             CONSTRUCTION BY LESSOR

                             [Intentionally Omitted]



                                    ARTICLE V

                        CONSTRUCTION, MAINTENANCE, REPAIR

                             AND OPERATION BY LESSEE



     Lessee may construct or install at its own expense any equipment,
improvements and facilities, and any additions thereto, upon all or any part of
the premises hereunder leased to Lessee for its exclusive use or preferential
use and may construct or install at its own expense, any equipment, improvements
and facilities authorized under Article I hereof upon any Airport property not
leased to Lessee for its exclusive use or preferential use at such locations as
may be approved by Lessor.  Plans and specifications of any proposed
construction or installation of improvements and facilities (including any
substantial alteration or addition thereto) shall be submitted to and receive
the prior approval of Lessor.  Lessor shall have the right to refuse approval of
such plans and specifications if the external appearance of such improvements
and 

                                     - 53 -

<PAGE>

facilities does not meet Lessor's reasonable requirements for substantial
uniformity of appearance of improvements and facilities on the Airport, or, if
the type or time of construction or installation, or the location thereof does
not meet Lessor's reasonable requirements for safe use of the Airport and
appurtenances by other authorized persons.  Lessor may, at its own cost, inspect
any such construction or installation.

     Lessee shall keep and maintain all premises hereunder leased to Lessee for
its exclusive use or preferential use and all such improvements and facilities
and additions thereto, whether constructed or installed by it upon premises
hereunder leased to it for its exclusive use or preferential use or upon Airport
property not leased to it for its exclusive use or preferential use, in good
condition and repair, reasonable wear and tear excepted, and damage by fire or
other casualty excepted.  Lessee shall not be liable for the repair or
restoration of damage to premises hereunder leased where such damage results

construction, installation, alteration, repair or maintenance or any such
equipment, improvements, facilities and additions.

     Lessee shall keep such premises leased to Lessee for its exclusive use or
preferential use in a sanitary and sightly condition, and shall provide all
necessary janitor services with respect thereto.

     In the event that Lessee fails to perform for a period of thirty days after

Lessee of a deviation from such plans and specifications and request for 
appropriate changes in such construction and installation, Lessor, upon the 
expiration of such thirty day period, may, but shall not be obligated to, 
enter upon the premises involved and perform such obligation of Lessee, 
charging Lessee the reasonable cost and expense thereof, and Lessee agrees to 
pay Lessor such charge in addition to any other amounts payable by Lessee 
hereunder; provided, however, that if Lessee's failure to perform any such 
obligation adversely affects or endangers the health or safety of the public 
or of employees of Lessor, and if Lessor so states in its aforesaid notice to 
Lessee, Lessor may but shall not be obligated to perform such obligation of 
Lessee at any time after the giving of such notice and without awaiting the 
expiration of said thirty day period, and charge to Lessee, and Lessee shall 
pay, as aforesaid, the reasonable cost and expense of such performance.  If 
Lessor shall perform any of Lessee's obligations in accordance with the 
provisions of this section, Lessor shall not be liable to Lessee for any loss 
of revenues to Lessee resulting from such performance.

of Lessee or of any of any of its employees, agents, passengers, guests,
patrons, invitees, or its or their suppliers of materials or furnishers of
service or any of its or their property, and if Lessee so states in its
aforesaid notice to Lessor, Lessee may but shall not be obligated to perform
such obligation of Lessor at any time after the giving of said notice and
without awaiting the expiration of said thirty day period, and Lessee may deduct
its reasonable costs of performance thereof from any rentals, fees or charges as
aforesaid.

     Lessor shall have the right to relocate at its own cost any equipment,
improvements and facilities constructed or installed by Lessee upon the Airport
property not leased hereunder to Lessee for its exclusive use pursuant to
authorization therefor under Article I hereof; provided, however, that such
relocation shall be performed in such a manner and at such times as are
calculated to reduce to the minimum possible under the circumstances any
interference with Lessee's operations at the Airport, and that the relocated
equipment, improvements and facilities shall, 

                                     - 58 -

and took the same quantity directly from such utility companies or suppliers. 
Lessor shall also supply electrical current to the ramp areas to be used by
Lessee in common with others and shall charge Lessee its appropriate share of
such electrical current at the rates hereinabove specified, which share shall be
prorated in accordance with Lessee's preferential use of gate positions.

facilities within such appropriate space leased to it in the Terminal Buildings
for such purposes, which club facilities shall be authorized to serve food and

fire, the elements, the public enemy or other casualty but not rendered
untenantable, the same shall be repaired with due diligence by Lessor at its own
cost and expense.  In case the Terminal Buildings are so damaged or destroyed by

become untenantable, the said buildings shall be repaired, reconstructed or
restored as the case may be, with due diligence by Lessor at its own cost and
expense, and the rent payable hereunder with respect to Lessee's exclusive space
or preferential space in said buildings shall be paid up to the time of such

have the right to cancel, or give notice of cancellation of, this Agreement
solely by reason of Lessee's failure or refusal to pay any part of the rentals,
fees or charges provided for in this Agreement if, within sixty (60) days after
such failure or refusal, Lessee shall have given to Lessor a written notice
stating that Lessee in good faith predicates such failure or refusal upon either

conditions herein contained to be performed, kept and observed by Lessee.  
The acceptance of rental by Lessor for any period or periods after a default

performed, kept and observed by Lessee, shall not be deemed a waiver of any 
right on the part of Lessor to cancel this Agreement for failure by Lessee to 
so perform, keep or observe any of the terms, covenants or conditions of this 
Agreement.

be served as hereinafter provided, upon or after the happening of any one of the
following events:

     (a)  The failure or refusal, for reasons beyond the control of Lessee, of
the FAA, at any time during the term of this Agreement or any renewal thereof,
to permit Lessee to operate into or from the Airport with any type of aircraft

<PAGE>

     (c)  The inability of Lessee due to circumstances beyond its control to
use, for a period in excess of ninety (90) days, the Airport or to exercise any
rights and privileges granted to Lessee hereunder and necessary to its
operations because of any law or ordinance, or because of any order, rule,
regulation or other action or any non-action of the FAA or any other
governmental authority, or, because of earthquake, other casualty (excepting
fire) or because of Acts of God or the public enemy;

     (d)  The default by Lessor in the performance of any covenant or agreement

cancellation, as above provided, shall be of any force or effect if Lessor shall
have remedied the default prior to receipt of Lessee's notice of cancellation.

     Lessee's performance of all or any part of this Agreement for or during any
period or periods after a default of any of the terms, covenants and conditions
herein contained to be performed, kept and observed by Lessor, shall not be
deemed a waiver of any right on the part of Lessee to cancel this Agreement for
failure by Lessor so to perform, keep or otherwise observe any of the terms,
covenants, or conditions hereof to be performed, kept and observed by Lessor, or
be construed to be or act as a waiver by Lessee of any subsequent default of any
of the terms, covenants and conditions herein contained to be performed, kept
and observed by Lessor.

                                   ARTICLE XVI

                            SUSPENSION AND ABATEMENT

     In the event that Lessor's operation of the Airport or Lessee's operation
at the Airport should be restricted substantially by action of any court of
competent 

                                     - 66 -

<PAGE>

jurisdiction or by action of the federal government or any agency thereof, or 
by action of the State of Michigan or any agency thereof, then either party 
hereto shall have the right, upon written notice to the other, to a 
suspension of this Agreement and an abatement of a just proportion of the 
services and facilities to be afforded hereunder, or a just proportion of the 
payments to become due hereunder, from the time of such notice until such 
restriction shall have been remedied and normal operations restored. 
Ascertainment of all matters under this Article shall be determined by 
agreement or by arbitration as provided in Article XVII hereof.

                                  ARTICLE XVII

                                   ARBITRATION

     If any controversy or claim should arise out of, under, or relating to, the
provisions of Articles III or XVI of this Agreement, then either party may by
notice in writing to the other, submit the controversy or claim to arbitration. 
The party desiring such arbitration shall give written notice to that effect to
the other party, specifying in said notice the name and address of the person
designated to act as arbitrator on its behalf.  Within fifteen (15) days after
the service of such notice, the other party shall give written notice to the
first party specifying the name and address of the person designated to act as
arbitrator on its behalf.  The arbitrators thus appointed shall appoint a third
disinterested person of recognized competence in such field, and such three
arbitrators shall as promptly as possible determine the controversy or claim.

     If the two arbitrators appointed by the parties shall be unable to agree
upon the appointment of a third arbitrator within fifteen (15) days after the
appointment of the second arbitrator, then within fifteen (15) days thereafter
either of the parties upon written notice to the other party, on behalf of both,
may request the appointment of a 

                                     - 67 -

<PAGE>

disinterested person of recognized competence in the field involved as the 
third arbitrator by the then chief judge of the United States District Court 
for the Eastern District of Michigan, Southern Division, or upon his failure, 
refusal or inability to act, may request such appointment by the then 
miscellaneous presiding judge of the Circuit Court (Third Judicial Circuit) 
of the State of Michigan, County of Wayne, or, upon his failure, refusal or 
inability to act, may apply to the Circuit Court (Third Judicial Circuit) of 
the State of Michigan, County of Wayne for the appointment of such third 
arbitrator, and the other party shall not raise any question as to the 
court's full power and jurisdiction to entertain the application and make the 
appointment. If none of the parties shall so request such appointment of a 
third arbitrator within fifteen (15) days after the expiration of the period 
within which the two arbitrators are to appoint a third arbitrator as 
hereinabove provided, the rights of each party to arbitrate the matter shall 
be deemed to have been waived and either of the parties may proceed to 
enforce whatever remedies, legal or otherwise, it may otherwise have.

     The decision in which any two of the three arbitrators so appointed and
acting hereunder concur shall in all cases be binding and conclusive upon the
parties.  Each party shall pay the fees and expense of the arbitrator appointed
by such party and one-half of the other expense of the arbitration properly
incurred hereunder.

     Each of the parties hereto agree that if, in the opinion of the other
party, any separate agreement is required by law in order to effectuate or
enforce the arbitration provisions hereinabove contained, it will execute such
separate agreement provided that the same is not inconsistent with the terms and
provisions of this Agreement.

     Lessee agrees to indemnify and hold Lessor harmless from and against all
liability for injuries to persons or damage to property caused by Lessee's use
and occupancy of or operations at the Airport; provided, however, that Lessee
shall not be liable for any injury, damage or loss caused by Lessor's sole
negligence or by the joint negligence of Lessor and any person other than
Lessee; and provided further that Lessor shall give to the Lessee prompt and
timely notice of any claim made or suit instituted which in any way, directly or
indirectly, contingently or otherwise, affects or might affect Lessee, and
Lessee shall have the right to compromise and defend the same to the extent of
its own interest.

     In addition to the foregoing, Lessee shall indemnify, defend and save
harmless Lessor, its commissioners, officers, agents, representatives and
employees and the County of Wayne from and against any and all lawsuits, claims,
loss and damages of any nature whatsoever, including damage to property of
Lessor and injury to or death of employees or agents of Lessor, arising either

referred to individually and collectively as the "Equipment") provided by Lessor
for Lessee's use, in common with other airlines, in or adjacent to International
Terminal Building 520 at the Airport; provided, however, that Lessee shall not
be liable for any injury or damage or loss caused by Lessor's sole negligence or
by the joint negligence of Lessor and any person other than Lessee or a
maintenance and repair contractor approved in writing by Lessee.  Lessor shall
give to Lessee prompt and timely notice of any claim made or suit instituted
which in any way 

                                     - 69 -

directly or indirectly, contingently or otherwise, affects or might affect

<PAGE>

          this Agreement.  Consequently the disadvantaged business enterprise
          requirements of 49 CFR Part 23 apply to this Agreement.

          2.   DBE OBLIGATION.  (i)  The recipient or its contractor agrees to
          ensure that disadvantaged business enterprises as defined in 49 CFR

          of contracts and subcontracts financed in whole or in part with
          Federal funds provided under this Agreement.  In this regard all
          recipients or contractors shall take all necessary and reasonable
          steps in accordance with 49 CFR Part 23 to ensure that disadvantaged

          discriminate on the basis of race, color, national origin, or sex in
          the award and performance of Department of Transportation-assisted

               Failure of a contractor or subcontractor to carry out the
          requirements set forth in paragraph 23.43(a) of 49 CFR Part 23 shall
          constitute a breach of contract and, after notification of the
          Department of Transportation, may result in termination of the
          Agreement or contract by the recipient or such remedy as the recipient
          deems appropriate.

               The definitions set forth in paragraph 23.5 of 49 CFR Part 23
          shall apply to the foregoing statements concerning disadvantaged
          business enterprises.

operator, rights or privileges with respect thereto which are not accorded to

     location selected by Lessee shall interfere with the reasonable use of the
     Airport by other authorized persons;

     15.  The right to conduct operations or activities other than those
     enumerated in Subparagraphs (1) to (14), inclusive, of this paragraph,
     reasonably related to the landing, taking off, flying, moving, loading,
     unloading, or servicing of aircraft which are reasonably necessary or
     convenient to the conduct by it of Air Transportation; provided, however,
     that all such other operations and activities shall be subject to the
     approval of the Lessor.

B.   LEASE OF SPACE:

     1.   EXCLUSIVE EXISTING TERMINAL SPACE.  As of the effectiveness of this
     Agreement, Lessor leases to Lessee, and grants to Lessee, its employees,
     agents, guests, patrons and invitees, the exclusive use of the Exclusive
     Existing Terminal Space identified on EXHIBIT C attached hereto
     (hereinafter referred to as "Lessee's Exclusive Existing Terminal Space");
     provided that, as of the effectiveness of this Agreement, EXHIBIT C shall
     be amended, if necessary, to delete any space which is reflected on EXHIBIT
     C but which is not then leased to Lessee in the Existing Terminal
     Facilities for its Air Transportation business and to add any space that is
     then leased to Lessee in the Existing Terminal Facilities for its Air
     Transportation business that is not then included on EXHIBIT C.  As

<PAGE>


     promptly as possible after the commencement of Lessee's Air Transportation
     business in the Midfield Terminal, but in any event not more than 60 days
     after such commencement, Lessee shall vacate Lessee's Exclusive Existing
     Terminal Space, and the lease hereunder of Lessee's Exclusive Existing
     Terminal Space shall terminate upon the later of (x) the earlier of the
     date Lessee vacates such space, and the date 60 days after such
     commencement and (y) the date on which the Northwest Demolition Project (as
     defined in the Project Development Agreement) shall have been completed. 
     Lessee and Lessor shall cooperate with one another in the transfer of
     Lessee's Air Transportation activities to the Midfield Terminal so as to
     (a) minimize the cost to Lessee and the inconvenience to Lessee and its
     passengers, (b) facilitate the relocation of other air carriers within the
     Existing Terminal Facilities and the renovation of space within the
     Existing Terminal Facilities, and (c) facilitate the demolition of the
     space in the Existing Terminal Facilities scheduled for demolition in
     accordance with the Project Development Agreement (hereinafter referred to
     as "Lessee's Existing Terminal Space To Be Demolished").

     2.   EXCLUSIVE MIDFIELD TERMINAL SPACE.  At such time as such space is
     available for beneficial occupancy, as evidenced by written notice thereof
     from Lessor to Lessee, Lessor leases to Lessee, and grants to Lessee, its
     employees, agents, guests, patrons and invitees, the exclusive use of the
     Exclusive Midfield Terminal Space generally identified on EXHIBIT D
     attached hereto (hereinafter referred to as "Lessee's Exclusive Midfield 
     Terminal Space").  Prior to commencement of Lessee's Air Transportation 
     business in the Midfield

                                   -8-

<PAGE>

     Terminal, an updated and revised EXHIBIT D agreed to by both
     parties shall be attached to this Agreement.

     3.   PREFERENTIAL MIDFIELD TERMINAL SPACE.

          (a)  At such time as such space is available for beneficial
          occupancy, Lessor grants to Lessee, its employees, agents, guests,
          patrons and invitees, the preferential use of space, improvements and
          facilities in the Midfield Terminal consisting of the Preferential
          Midfield Terminal Space generally identified on EXHIBIT D attached
          hereto (hereinafter referred to as "Lessee's Preferential Midfield
          Terminal Space").  Prior to commencement of Lessee's Air
          Transportation business in the Midfield Terminal, an updated and
          revised EXHIBIT D agreed to by both parties shall be attached to this
          Agreement.  Lessee shall have the right to permit its code share
          partners and commuter carriers to have access to Lessee's Preferential
          Midfield Terminal Space.

          (b)  Preferential Midfield Terminal Space shall be available to Lessee
          in accordance with the following preferential use provisions:

               (i)  Lessee shall have priority in using such space, subject to
          the provisions of subsection (iii) below.  In addition, Lessor hereby
          grants to Lessee, and Lessee hereby accepts from Lessor, for so long
          as Lessee leases the premises preferentially leased pursuant to
          Article IB.3.(a), the preferential right to use the aircraft parking
          positions adjacent to such preferentially leased premises, as shown on
          EXHIBIT D, for the  parking of aircraft and support vehicles and the
          loading and unloading of passengers and cargo.

                                   -9-

<PAGE>



               (ii)  Lessor intends to maintain a policy of providing open
          access to the Airport and achieving a balanced utilization of Airport
          facilities.  To achieve that goal, Lessor reserves the right to
          require shared use of Preferential Use Premises as described in
          subsection (iii) below.

               (iii)  (A)  If an airline, including any airline seeking to
          expand its service or an airline seeking entry into the Airport, is
          in need of space or facilities at the Airport after the Date of
          Beneficial Occupancy of the Midfield Terminal, which need cannot be
          met by use of then unleased premises, if any, in the Existing Terminal
          Facilities or expansions thereto, Lessor shall direct such airline to
          request the use of leased space or facilities of all Signatory
          Airlines on a voluntary basis. Lessee and the other Signatory Airlines
          shall make reasonable efforts to accommodate such requests in a timely
          manner from any Preferential Use Premises leased to them.

                      (B)  In the event (I) Lessor receives a written request
          from an airline requesting space or facilities of a type granted to
          Signatory Airlines on a preferential use basis, (II) the requesting
          airline demonstrates to Lessor that it has contacted all Signatory
          Airlines and has exhausted all reasonable efforts to find reasonable
          accommodation for its proposed operations and the space or facilities
          it needs, and (III) Lessor determines that (x) such requesting airline
          needs the requested space or facilities to accommodate passengers or
          aircraft and (y) Lessor cannot provide such space or facilities to
          such airline on a timely basis, then Lessor may grant such requesting
          airline the right of temporary or shared use of a

                                   -10-

<PAGE>


          designated portion of Lessee's Preferential Midfield Terminal Space,
          including, but not limited to, the use of passenger loading bridges
          and other appurtenant equipment which are reasonably necessary for the
          effective use of such space, whether owned by the Lessee or the
          Lessor, as well as the aircraft parking positions adjacent to such
          space.

                      (C)  In the event Lessor determines that a requesting
          airline's needs require granting such requesting airline the right to
          share or temporarily use Preferential Use Premises, Lessor shall serve
          written notice to all Signatory Airlines of that determination and
          notice of Lessor's intention to make a further determination, in not
          less than 15 calendar days, as to how the requesting airline will be
          accommodated.

                      (D)  In accordance with the rules and priorities set forth
          in subparagraph (F) below, Lessor may grant the requesting airline the
          right of shared or temporary use of a designated portion of Lessee's
          Preferential Midfield Terminal Space, as well as rights of ingress and
          egress, the right to use the aircraft parking positions adjacent
          thereto and the right to use passenger loading bridges and other
          appurtenant equipment are reasonably necessary for the effective use
          of such space, provided, that:

                           (I)  such proposed user provides Lessee with
               indemnification and proof of insurance satisfactory to Lessee;
               provided, however, that  Lessee may not require any
               indemnification more favorable to it than that which Lessee
               provides to Lessor hereunder;

                                   -11-

<PAGE>


                           (II)  such proposed user agrees to pay Lessee the sum
               of the following:

                                 (x) an amount equal to a pro rata share of the
                      sum of the terminal rentals and any other applicable
                      payments, fees or taxes payable by Lessee hereunder with
                      respect to such areas during such shared or temporary use
                      period as calculated herein; and

                                 (y) additional amounts sufficient to recover
                      Lessee's direct costs and operation and maintenance
                      expenses, if any, of such shared or temporary use,
                      including a reasonable allocation of any capital and
                      equipment costs for property and equipment owned by
                      Lessee;

                           (III)  such proposed user enters into a written
               agreement with Lessee therefor, which agreement shall not be
               inconsistent with the terms and conditions stated herein and
               shall be submitted to Lessor for written approval prior to the
               effective date thereof.

                      (E)  Lessee agrees to make reasonable efforts to
          facilitate the temporary or shared accommodation of the requesting
          airline's scheduled operations, including the use of Lessee's
          passenger loading bridges and other portions of the Lessee's
          Preferential Midfield Terminal Space as may be reasonably necessary
          to accommodate the requesting airline in the event Lessor requires
          such use.  In the event that the requesting airline and Lessee are not
          able to agree to a form of written

                                   -12-

<PAGE>


          agreement pursuant to subparagraph (D)(III) above after reasonable
          efforts by both parties, Lessor shall have the right, after
          consultation with both parties, to set the final terms of such written
          agreement, which shall provide no less protection of Lessee's
          interests than Lessee provides for Lessor's interest hereunder, and be
          binding on both the requesting airline and Lessee.

                      (F)  In the event that, pursuant to subparagraph (B)
          above, Lessor determines that a requesting airline is in need of
          facilities to accommodate passengers or aircraft and such facilities
          should be made available from Preferential Use Premises, Lessor will
          follow the following rules and priorities in designating the specific
          premises for temporary or shared use by the requesting airline:

                           (I)  Preferential Use Premises shall be designated
               for temporary or shared use in the reverse order of the magnitude
               of the then present utilization by Signatory Airlines.  

                           (II) In assessing the degree of such utilization by
               Signatory Airlines, Lessor will consider all factors deemed
               relevant, which may include:  (u) the average number of flight
               arrivals and departures per aircraft parking position per day;
               (v) flight scheduling considerations; (w) potential labor
               conflicts; (x) the number, availability and type (e.g. wide-body
               or narrow body) of aircraft parking position locations; (y) the
               preferences of the Signatory Airlines as to which of their
               specific premises are

                                   -13-

<PAGE>


               designated for temporary or shared use by the requesting airline
               and (z) other operational considerations.

                           (III)  In the event Lessee is required to share
               Lessee's Preferential Midfield Terminal Space, Lessee shall have
               priority in all aspects of usage of such shared premises over all
               other airlines; provided that Lessee shall not change its
               scheduling or ordinary course usage of such premises for the
               purpose of interfering with the usage of such premises by a
               requesting airline sharing such premises.

                           (IV) Notwithstanding the foregoing, Lessee shall not
               be required to make any of Lessee's Preferential Midfield
               Terminal Space available during any consecutive two calendar
               quarters in the event that, for the six months preceding such
               consecutive two calendar quarter period, Lessee shall have
               maintained an average level of 200 flights per day departing from
               the Midfield Terminal.  For purposes of calculating the number of
               flights per day of Lessee departing from the Midfield Terminal,
               Lessee's flights shall be deemed to include the jet flights of
               Lessee and KLM and shall not include Lessee's code share partners
               other than KLM, commuter carriers, or any other air carriers
               whose Air Transportation operations are handled by Lessee at the
               Airport. If Lessee does not meet the foregoing utilization
               standard in any six month period, Lessor may require Lessee to
               make available during the following two consecutive calendar
               quarters, pursuant to and in accordance

                                   -14-

<PAGE>


               with the provisions of this Article IB.3.(b)(iii), not more than
               the minimum number of gates which, if not under lease to Lessee
               in such prior six month period, would have resulted in an average
               of not less than three departing flights of Lessee (calculated as
               aforesaid) per gate per day for such prior six month period with
               respect to Lessee's remaining gates.

                      (G) The foregoing provisions of this Article IB.3.(b)(iii)
          notwithstanding, Lessor may grant a requesting airline the right to
          temporarily use a designated portion of Lessee's Preferential Midfield
          Terminal Space in non-recurring emergency or safety-related
          circumstances, so long as such use will not unreasonably adversely
          affect Lessee's Air Transportation operations at the Airport.

                      (H)  During the use of Lessee's Preferential Midfield
          Terminal Space or other related facilities by other airlines scheduled
          by Lessor pursuant to this Article IB.3., Lessee shall not be held
          liable by Lessor with regard to any claim for damages or personal
          injury arising out of or in connection with such requesting airline's
          use of Lessee's Preferential Midfield Terminal Space or other related
          facilities, unless caused by the negligence of Lessee, its employees
          or agents.

                      (I)  In the event that Lessee shall be required to share
          its Preferential Midfield Terminal Space pursuant hereto, until such
          time as alternative facilities at the Airport are provided to airlines
          being accommodated in Lessee's Preferential Midfield Terminal Space,
          Lessee must continue to share such space with the accommodated 
          airlines, even 

                                      15

<PAGE>

          if Lessee thereafter meets the utilization standards set forth in 
          subsection (F)(IV) above.  Lessor agrees that, under such 
          circumstances, upon an affirmative vote of a Weighted Majority for
          necessary capital improvements, Lessor shall take all practical steps
          to construct and provide additional terminal facilities at the site of
          the Existing Terminal Facilities to provide permanent space for the
          airline being  accommodated by Lessee.

     4.   JOINT USE MIDFIELD SPACE.  At such time as such space is available for
     beneficial occupancy, Lessor grants to Lessee, its employees, agents,
     guests, patrons and invitees, the joint use, along with all other air
     carriers operating Air Transportation businesses in the Midfield Terminal
     to whom such joint use has been granted, of space, improvements and
     facilities in the Midfield Terminal consisting of the Joint Use Midfield
     Terminal Space identified on EXHIBIT D attached hereto (hereinafter
     referred to as "Lessee's Joint Use Midfield Terminal Space").

     5.   COMMON USE MIDFIELD TERMINAL SPACE.  At such time as such space is
     available for beneficial occupancy, Lessor grants to Lessee, its employees,
     agents, guests, patrons and invitees, the common use, along with all other
     air carriers operating Air Transportation businesses in the Midfield
     Terminal, of space, improvements and facilities in the Midfield Terminal
     consisting of the Common Use Midfield Terminal Space identified on EXHIBIT
     D attached hereto (hereinafter referred to as "Lessee's Common Use Midfield
     Terminal Space"). The Common Use Midfield Terminal Space shall be allocated

                                   -16-

<PAGE>


     for use by the users thereof in accordance with the priorities
     described in Exhibit D-1 attached hereto.

C.   PUBLIC SPACE:  Lessee, its employees, passengers, guests, patrons and
invitees, in common with others, shall have the use of all public space in the
Existing Terminal Facilities and the Midfield Terminal, and all additional
public space which may thereafter be made available therein and in any additions
thereto, including, without limiting the generality thereof, lobbies, passenger
lounges and waiting rooms, hallways, rest rooms and rooms for other public and
passenger convenience.

D.   PARKING SPACE:  Vehicular parking spaces shall be provided near the
Existing Terminal Facilities (adequate in Lessor's judgment, considering the
number of vehicles and traffic to be accommodated) and the Midfield Terminal for
the use of Lessee, its employees, passengers and limousine operators, in common
with any other scheduled air transportation companies, their employees,
passengers and limousine operators.  Lessor or its concessionaires may make a
reasonable charge to passengers for the use of the parking space provided for
them, but no charges shall be made for use of such adequate parking spaces as
are designated by Lessor for the respective use of Lessee's employees or
limousine operators.

E.   RIGHT OF INGRESS AND EGRESS:  Subject to the reasonable rules and
regulations promulgated by Lessor in accordance with Article XI hereof, Lessee
shall have the right and privilege over the Airport of ingress to and egress
from the premises and facilities described in this Article I for its employees,
agents, passengers, guests, patrons and invitees, its or their suppliers of
materials and furnishers of service, its or their aircraft, equipment, vehicles,
machinery and other property, and, except as herein otherwise specifically
provided, no charges, fees or tolls of any nature, direct or indirect,

                                   -17-

shall be imposed by Lessor upon Lessee, its employees, agents, passengers, 
guests, patrons and invitees, its or their suppliers of materials and 
furnishers of service for such right of ingress and egress, or for the 
privilege of purchasing, selling or using any materials, or services 
purchased or otherwise obtained by Lessee, or for transporting, loading, 
unloading or handling persons, property, cargo or mail in connection with 
Lessee's business or exercising any right or privilege granted by Lessor 
hereunder.  Nothing in this Article I shall limit Lessor's right to impose, 
collect and use PFCs.

F.   FUEL:  Lessee shall have the right during the term of this Agreement to
lease land in the common fuel storage area as shown in the Airport Master Plan,
at a rental rate of not to exceed five cents ($.05) per square foot per year,

and amount of such land to be determined by written agreement of the parties
hereto, a copy of which agreement, if entered into prior to the effective date

provided that the foregoing shall not be construed to prohibit Lessor from
imposing and collecting charges and fees from passengers for the use of the
public auto parking areas on the Airport, from operators of ground

     1.   EXCLUSIVE EXISTING TERMINAL SPACE:  For so long as Lessee shall retain
     any Lessee's Exclusive Existing Terminal Space pursuant to Article IB.1.,
     Lessee shall be obligated to pay rental charges for such premises equal to
     that which would have been applicable for such space under the Basic

          (a)   Lessee shall pay the following Midfield Exclusive and
          Preferential Rental Charges: 

               (i) commencing on the date on which the first facilities in the
          Midfield Terminal become available for beneficial occupancy by Lessee,
          as evidenced by written notice thereof from Lessor to Lessee, for each
          Fiscal Year or portion thereof (on a pro rated basis), through Fiscal
          Year 2008, Lessee shall pay an amount equal to the product of the
          total number of square feet of Lessee's Exclusive Midfield Terminal
          Space and Lessee's Preferential Midfield Terminal Space multiplied by
          the following rental rates per square foot for the following Fiscal
          Years:

               2001     $17.92          2005     $19.71
               2002      17.92          2006      19.71

          rated basis), Lessee shall pay an amount equal to (x) the product of
          (I) the total number of square feet, if any, of Lessee's Exclusive
          Midfield Terminal

          Space and Lessee's Preferential Midfield Terminal Space in each case
          in the Domestic Area of the Midfield Terminal multiplied by (II) the
          Midfield Domestic Exclusive and Preferential Rental Rate for such 
          Fiscal Year, plus (y) the product of (I) the total number of square 
          feet, if any, of Lessee's Exclusive Midfield Terminal Space and 
          Lessee's Preferential Midfield Terminal Space in each case in the 
          International Area of the Midfield Terminal multiplied by (II) the 
          Midfield International Exclusive and Preferential Rental Rate for such
          Fiscal Year.

          (b)  The Midfield Domestic Exclusive and Preferential Rental Rate for

          (c)  The Midfield International Exclusive and Preferential Rental Rate
          for any Fiscal Year shall be the sum of the Midfield International O&M
          Rate for such Fiscal Year and the Midfield International Bond Debt
          Service Rate for such Fiscal Year.  The Midfield International O&M
          Rate for any

                                   -21-

<PAGE>


          Fiscal Year shall be determined by dividing (i) Midfield O&M Expenses
          for such Fiscal Year allocated to the International Area of the
          Midfield Terminal by (ii) the total number of Useable Square Feet in
          the International Area of the Midfield Terminal.  The Midfield
          International Bond Debt Service Rate for any Fiscal Year shall be
          determined by dividing (i) Bond Debt Service allocated to the
          International Area of the Midfield Terminal for such Fiscal Year by
          (ii) the total number of Useable Square Feet in the International Area
          of the Midfield Terminal.

          (d)  Lessor shall maintain accurate records allocating Bond Debt
          Service for each Fiscal Year between (i) the Midfield Terminal, (ii)
          the Existing Terminal Facilities and (iii) the rest of the Airport,
          and within the Midfield Terminal, between (A) the Domestic Area of the
          Midfield Terminal and (B) the International Area of the Midfield
          Terminal.  The allocation of Bond Debt Service to the Midfield
          Terminal, the Existing Terminal Facilities and the rest of the Airport
          shall be based on capital expenditures made out of the proceeds of
          Bonds.  Bond Debt Service shall be allocated within the Midfield
          Terminal to the Domestic Area of the Midfield Terminal and the
          International Area of the Midfield Terminal as set forth on EXHIBIT E
          attached hereto.

          (e)  Commencing with the Fiscal Year in which the Date of Beneficial
          Occupancy of the Midfield Terminal occurs, for each Fiscal Year an
          amount of PFC revenues equal to the lesser of (i) the PFC revenues
          received by Lessor in such Fiscal Year that are attributable to a PFC
          of $3, and (ii) the PFC revenues received by Lessor in Fiscal Year
          2001 that are

                                   -22-

<PAGE>


          attributable to a PFC of $3, shall be allocated by Lessor to the
          Midfield Terminal and the Existing Terminal Facilities on a pro rata
          basis in accordance with the capital expenditures for the Midfield
          Terminal and the Existing Terminal Facilities made out of the proceeds
          of Bonds that are approved for PFC funding, and, for purposes of
          calculating Terminal Charges payable by Lessee, such PFC revenues
          allocated to the Midfield Terminal and the Existing Terminal
          Facilities shall be netted, on the same pro rata basis, against the
          Bond Debt Service allocated to the Midfield Terminal and the Existing
          Terminal Facilities, as the case may be, for such Fiscal Year.  The
          foregoing notwithstanding, for the Fiscal Year in which the Date of
          Beneficial Occupancy of the Midfield Terminal occurs, the amount of
          PFC revenues otherwise allocable to the Midfield Terminal and the
          Existing Terminal pursuant to the immediately preceding sentence shall
          be reduced by a fraction the numerator of which is the number of
          calendar months in such Fiscal Year preceding the month in which the
          Date of Beneficial Occupancy of the Midfield Terminal occurs, and the
          denominator of which is 12.

          (f)  Lessor shall maintain accurate records identifying O&M Expenses
          for each Fiscal Year and allocating such expenses among (i) the
          Midfield Terminal, (ii) the Existing Terminal Facilities and (iii) the
          rest of the Airport, and within the Midfield Terminal, among (A) the
          Domestic Area of the Midfield Terminal and (B) the International Area
          of the Midfield Terminal, in conformity with the methodologies set
          forth in EXHIBIT F attached hereto.

          for such Fiscal Year pursuant to the provisions of the Bond Ordinance;
          plus

                                   -30-

<PAGE>


          (4)  commencing in Fiscal Year 2001, an amount equal to $5 million
          (which amount shall be escalated each Fiscal Year beginning in Fiscal
          Year 2002 to reflect percentage increases in the Producer Price Index 
          during the most recently ended 12-month period for which such index is
          available) minus the amount, if any, deposited for such Fiscal Year
          into the ACE Account; plus

          (5)  commencing in the Fiscal Year in which no Airport Revenue Bonds
          are subject to Paid-in Coverage (as defined in Article IIB.2.(a)
          below), $350,000; minus

          Lessor is on an accrual accounting basis] during such Fiscal Year
          (excepting Special Facility Revenues).

     The unit thus arrived at shall be the Activity Fee rate per thousand pounds
of Approved Maximum Landing Weight payable by Lessee to Lessor for such of
Lessee's aircraft, or aircraft of its subsidiary, as have landed at the Airport
during the Fiscal Year for which such calculation is made.

     The Activity Fee as herein established shall not be subject to further
adjustment except by agreement of the parties hereto, or as provided in Article
IIIF.

          produce revenues from concessionaires, tenants, and users of a nature
          and amount which would be produced by a reasonably prudent operator of
          an airport.

               (iii) That it will comply in all respects with the revenue
          retention requirement in Section 511(a)(12) of the Airport and Airway
          Improvement Act of 1982, as amended, now codified at 49 U.S.C. Section
          47107(b).  Commencing in Fiscal Year 1997, Lessor may include in O&M
          Expenses for each Fiscal Year administrative charges not in excess of
          $5 million, provided that the foregoing cap amount shall be escalated
          each Fiscal Year, commencing in Fiscal Year 1998, by multiplying the
          prior year's cap amount by a factor of one (1) plus the percentage
          increase, if any, in the index of average hourly earnings for
          production workers for manufacturing industries in the United States,
          as published by the United States Department of Labor, Bureau of Labor
          Statistics (or if this index is discontinued or otherwise becomes
          unavailable to the public, the most nearly comparable index of such
          average hourly earnings published by a recognized financial
          institution, financial publication or university) during the most
          recently ended 12-month period for which such index is available.
          The annual

                                      -32-

<PAGE>


          administrative charges of $5 million shall pay for all services
          provided directly or indirectly by any department, division or agency
          of Lessor other than the Airport, or Central Communications to the
          extent operated by the Airport, in the nature of administration and
          legislative oversight, finance, budget, accounting, legal, payroll,
          purchasing, personnel, information processing, imaging, planning and
          development. Administrative charges shall not include (A) optional
          contracted services by the Airport, such as landscaping, mowing,
          engineering (design, construction, inspection and project management)
          and mechanical, electrical and plumbing trade services to be performed
          on Airport property, or (B) payroll and fringe benefit costs for the
          employee positions described in Exhibit H; provided that any increase
          in such costs or the number of such positions above those shown on
          Exhibit H must be approved by a majority in number of the Signatory
          Airlines.

               (iv) That it will utilize competitive bidding procedures for the
          award of all maintenance and operation contracts and construction
          contracts for the Airport.

               (v)  That all senior appointed Airport officials shall have
          professional qualifications commensurate with the responsibilities of
          the jobs to be performed by such officials.

               (vi) That it will take all necessary actions to assure that the
           personnel of Lessor, whose wages and benefits are included in O&M
           Expenses, are actually performing work for the Airport as represented
           by such inclusion.

                                      -33-

<PAGE>


               (vii)  That it will operate Willow Run Airport only as a reliever
          airport for the Airport with no scheduled air carrier or public
          charter passenger service.

               (viii) That PFC revenues received by Lessor in each of Fiscal
          Years 2002, 2003, 2004, 2005, 2006, 2007 and 2008 that exceed in such
          year, by reason of increases in passenger activity levels at the
          Airport, the amount of PFC revenues received by Lessor in Fiscal Year
          2001 that is attributable to a PFC of $3 shall be used by Lessor to
          pay for capital projects in the Capital Improvement Program attached
          hereto as EXHIBIT G that are approved by a Weighted Majority and by
          the FAA for PFC funding, whether on a pay-as-you-go basis or to pay
          Bond Debt Service on Bonds issued to fund such projects.

               (ix) That PFC revenues received by Lessor through Fiscal Year
          2008 that are attributable to increases in the PFC from $3 per
          enplaned passenger shall be applied (A) as required by FAA Letter of
          Intent No. AGL-90-01, Amendment No. 7, dated August 21, 1996, and then
          (B) to capital projects at the Airport for safety or security, or to
          FAA required capital projects, so long as such projects are approved
          by the FAA for PFC funding, and then (C) to capital projects in the
          Capital Improvement Program attached hereto as EXHIBIT G that are
          approved by the FAA for PFC funding.

          Lessor and Lessee recognize that payment of the Activity Fee, as
     herein provided, together with other funds, will result in an annual
     surplus, because, among other things, Ordinance 319 currently requires the
     collection by Lessor

                                   -34-

<PAGE>


     of rates and charges necessary to produce in each Fiscal Year revenues that
     include 125% of the principal and interest due in such year on Airport
     Revenue Bonds (exclusive of capitalized interest thereon) (the excess 25%
     required to be collected is herein referred to as "Paid-in Coverage").
     Lessor covenants to utilize such surplus only for the retirement of Bonds
     or as follows:

          (1)  Fifty percent (50%) of the amount attributable to the Paid-in
          Coverage, if any, on the Airport Revenue Bonds shall be deposited into
          the Airline Equity Account and allocated among the Airline Equity
          Subaccounts in accordance with the respective landed weights of each
          Signatory Airline for the applicable period;

          (2)  Three Hundred Fifty Thousand Dollars ($350,000) shall be
          deposited annually into the County Discretionary Fund;

          (3)  Fifty percent (50%) of the amount attributable to the Paid-in
          Coverage, if any, on the Airport Revenue Bonds (less $350,000
          annually) shall be deposited into the ACE Account;

          (4)  Deposits shall be made into the Subordinate Bond Reserve Account,
          the Operation and Maintenance Reserve Fund and the Renewal and
          Replacement Fund pursuant to the provisions of Ordinance 319, and into
          any other funds for similar purposes established pursuant to other
          ordinances under which Bonds are issued; and

          (5)  Amounts includible each Fiscal Year in the Revenue Requirement
          pursuant to item (4) of the definition thereof in Article IIIB.1.
          shall be deposited into the Airport Development Fund, to be
          established and held by Lessor for the purposes described in Article
          IIIB.2.(c)(4) below.

                                   -35-

<PAGE>



     (b)  Lessor may issue Bonds to finance the costs (including all reasonable
     costs incidental to the issuance and sale of such bonds) of capital
     projects and may include the Bond Debt Service (including, among other
     things, coverage requirements) on such Bonds in Lessee's fees hereunder
     only after first receiving approval of a Weighted Majority for such capital
     projects.

          Lessor may assign, in accordance with the Bond Ordinance and the terms
     of this Agreement, certain of its interests in and pledge certain revenues
     and receipts of the Airport as security for payment of the principal of,
     premium, if any, and interest on Bonds.  Except as set forth in the
     preceding sentence and except for residential property acquired by the
     Airport pursuant to the Airport's noise mitigation program, Lessor shall
     not pledge, sell, convey, mortgage, encumber, assign or otherwise transfer
     the Airport or any portion thereof during the term of this Agreement.

     (c)  The following limitations shall apply to expenditures from the below-
     described funds and accounts:

          (1)  EXPENDITURES TO BE MADE FROM THE COUNTY DISCRETIONARY FUND.
          Lessor may make expenditures from the County Discretionary Fund
          without approval by the air carriers for any lawful Airport-system
          purpose, except that expenditures for Willow Run Airport shall only be
          made if Lessor is in compliance with its covenant in Article III
          B.2.(a)(vii).

          (2)  CAPITAL EXPENDITURES TO BE MADE FROM THE ACE ACCOUNT.  If Lessor
          proposes to make a capital expenditure from the ACE Account it shall
          be subject to the approval of the air carriers if such capital
          expenditure greater than Fifty Thousand dollars ($50,000).  Such
          approval shall be

                                   -36-

<PAGE>


          deemed given unless within thirty (30) days after receipt of Lessor's
          proposal to make such expenditure Lessor is notified by a
          Majority-in-Interest of the air carriers that such expenditure is
          disapproved, such notification to contain specific reasons and grounds
          therefor.

          (3)  EXPENDITURES TO BE MADE FROM THE AIRLINE EQUITY SUBACCOUNTS. 
          Each Signatory Airline may choose to use any amounts deposited into
          its Airline Equity Subaccount for any of the following purposes:

               (i)   as a direct credit against Activity Fees payable by it;

               (ii)  for capital expenditures at the Airport; or

               (iii) to service Special Facility Revenue Bond debt for capital
               improvements at the Airport.

          (4)  EXPENDITURES TO BE MADE FROM AIRPORT DEVELOPMENT FUND.  
          Lessor may make capital expenditures from the Airport Development Fund
          without approval by the air carriers for any lawful Airport-system
          related purpose, provided that Lessor shall not pledge the Airport
          Development Fund as security for any Bond or other debt of Lessor
          without approval of a Majority-in-Interest of the air carriers, and
          provided, further, that capital expenditures for Willow Run Airport
          shall only be made if Lessor is in compliance with its covenant in
          Article III B.2.(a)(vii).

     (d)  In order to permit Lessor to issue Bonds in compliance with applicable
     securities laws, Lessee agrees that, upon the request of Lessor, Lessee
     shall provide to Lessor such information with respect to Lessee as Lessor
     deems reasonably necessary in order for Lessor to issue Bonds in compliance
     with the requirements of Rule 15c-2(12) of the Securities and Exchange
     Commission.

                                   -37-

C.   CHARGES FOR ELECTRICAL CURRENT:  Lessee shall pay to Lessor for Lessee's
use and occupancy of Exclusive Use Premises, Preferential Use Premises, Joint
Use Premises and Common Use Premises under this Agreement, a charge for
electrical current furnished by Lessor to each such area, said charge to be
computed as follows:

     (1)  In metered areas at a rate not exceeding that which Lessee would have
          to pay if it established the same demand and took the same quantity
          directly from the public utility (or other third party provider)
          supplying electrical current to the Midfield Terminal.

     (2)  In unmetered areas at a rate per square foot of occupied space as
          established by an electrical consultant appointed by Lessor.  In the
          event the parties hereto shall be unable to agree on the
          aforementioned charges, the controversy shall be subject to
          arbitration in the manner provided in Article XVII of this Agreement.

     (3)  In Common Use Premises the electrical current charge shall be shared
          with the other common users, 20% equally and 80% to be allocated on
          the basis of enplaned passengers.

     (4)  In Joint Use Premises the electrical current charge shall be shared by
          the users of such premises based on the number of passengers of each
          such user.

D.   CHARGES FOR WATER AND SEWERAGE FACILITIES:  Lessor shall charge Lessee for
water and sewerage facilities supplied to Lessee's Exclusive Use Premises and
Preferential Use Premises and the amount of such charge shall be subject to
future agreement of the parties hereto.  In the event the parties hereto shall
be unable to agree

                                   -38-

<PAGE>


on such amount, the controversy shall be subject to arbitration in the manner 
provided in Article XVII of this Agreement.

E.   CONTINUING RENTAL OBLIGATION

     1.   Should any scheduled air carrier, including Lessee, having an
agreement with Lessor substantially similar to the Basic Agreement or this
Agreement, terminate its operations at the Airport by reason of the loss of its
operating authority to serve the Detroit Metropolitan Area and exercise the
right of cancellation provided for in such case in Article XV of the Basic
Agreement or in this Agreement, its continued obligation to pay to Lessor
charges thereafter due under the Basic Agreement or this Agreement, including
space rentals and Activity Fees, shall, subject to the provisions of the
paragraph next following, thereupon terminate.  Payment of rentals and Activity
Fees thereafter required shall be the responsibility of such of the other
aforesaid scheduled air carriers which continue to provide air transportation
service to the Detroit Metropolitan Area.

     Should (a) all such aforesaid air carriers lose their operating authority
to serve the Detroit Metropolitan Area, or (b) should Lessor fail to maintain
the necessary certifications required to permit scheduled air carrier operations
at the Airport, and ALL of such air carriers exercise the right of cancellation
provided for in either event in said Article XV, the obligation to pay such
aforesaid charges shall terminate subject, however, to the following condition. 
Until Fiscal Year 2009, upon such termination all such aforesaid carriers then
operating at the Airport (including Lessee if such be the case) shall be
obligated, to the extent hereinafter required, to pay annually, or in such
installments as Lessor may require, an amount not in excess of three hundred
percent (300%) of their respective annual rentals (calculated in the manner set
forth in

                                   -39-

<PAGE>


paragraph 2 immediately below) payable at that time for terminal building 
space at the Airport (whether leased under the Basic Agreement, this 
Agreement or otherwise) for the purpose of providing funds to be applied to 
Bond Debt Service (exclusive of any additional coverage) on the then 
outstanding issues of Bonds.  Payments required of such carriers shall be 
assessed against each of them in a uniform manner per square foot leased and 
shall be diminished pro rata to the extent that Airport revenues or capital 
funds are realized from other sources and are available for application to 
the debt service on the said Bonds as provided for in Subparagraph 3 below.

     2.   For the purpose of calculating payments which such carriers may be
obligated to make, Lessor shall first determine the average annual rental rate
per square foot paid for such terminal building space by all such carriers by
dividing their total annual rentals for such space by the total square footage
of the space.  The square footage leased by each carrier shall then be
multiplied by such average rate in order to obtain an annual rental of each such
carrier for the purpose of establishing the three hundred percent (300%) maximum
annual limitation.

     3.   In the event Lessor fails to maintain the necessary certifications
required to permit scheduled air carrier operations at the Airport and
thereafter operates at the Airport for other purposes, any revenues earned as a
result shall, after providing for necessary operating and maintenance expenses,
be first applied each year to such debt service requirements before requiring
payments by the carriers pursuant to paragraph 1 above.  In the foregoing
circumstances and as long as any of the aforesaid Bonds are outstanding, Lessor
shall use its best efforts to operate or lease the Airport properties so as to
produce sufficient revenues to satisfy the requirements of the aforesaid Bonds. 
If under such circumstances the Airport properties or portion thereof are sold
by Lessor,

                                   -40-

<PAGE>


the proceeds of such sale(s) shall first be used (or set aside) and be 
applied to current and future debt service requirements or to retire the 
aforesaid Bonds before requiring payments by the carriers pursuant to 
subparagraph 1 above.

F.   PAYMENT OF RENTALS AND ACTIVITY FEES

     1.   INFORMATION ON LESSEE OPERATIONS:

          (a)  Not earlier than 120 days nor later than 90 days prior to the
          last day of each Fiscal Year, Lessee shall furnish Lessor with an
          estimate for the next ensuing Fiscal Year of (i) the total Approved
          Maximum Landing Weight of all aircraft to be landed at the Airport by
          Lessee, (ii) the total number of enplaned domestic and international
          passengers and deplaned domestic and international passengers of
          Lessee, (iii) the total number of arriving and departing domestic and
          international flights of Lessee, and (iv) the Midfield O&M Expenses to
          be reimbursed to Lessee pursuant to Article VII.B.

          (b)  Lessee shall, no later than the 20th day of each calendar month,
          transmit to Lessor a report, certified by Lessee, setting forth (i)
          the actual number of Lessee's enplaned passengers and deplaned
          passengers for the preceding calendar month, (ii) the actual aggregate
          Approved Maximum Landing Weight for all aircraft operated by Lessee
          and landed at the Airport during the preceding calendar month,
          (iii) the actual number of Lessee's arriving and departing domestic
          and international flights for the preceding month, and (iv) the
          Midfield O&M Expenses actually paid by Lessee pursuant to Article
          VII.B. for the preceding calendar month.

                                   -41-

<PAGE>


     2.   PROJECTION OF RENTALS AND ACTIVITY FEES:  Not later than 60 days prior
to the end of each Fiscal Year, Lessor shall furnish Lessee with a projection
for the next ensuing Fiscal Year (the "Projection") of the Terminal Charges to
be paid hereunder, and the Activity Fee rate per thousand pounds of Approved
Maximum Landing Weight.  Such Projection will include Lessor's proposed Airport
budget, and shall set forth a calculation of the Activity Fee (including all
sources of revenue and all expenses) for the next ensuing Fiscal Year, together
with other information relevant thereto reasonably requested by Lessee.  Lessor
shall give due consideration to any suggestions and comments made by Lessee with
respect to the Projection.  The Projection, as revised by Lessor after
considering Lessee's suggestions and comments, shall be the basis for computing
Lessee's Terminal Charges and Activity Fees for the next ensuing Fiscal Year
unless and until otherwise revised pursuant to paragraph 4 below.

     3.   PAYMENT OF RENTALS AND ACTIVITY FEES:

          (a)  Not later than the 20th day of each calendar month of each Fiscal
          Year, Lessee shall pay Lessor, without demand or invoice, an amount
          equal to 1/12 of Lessee's aggregate Terminal Charges for such Fiscal
          Year, computed in accordance with Article IIIA, and based on the
          Projection, as such projection may have been revised pursuant to
          paragraph 4 below.

          (b)  Not later than the 20th day of each calendar month of each Fiscal
          Year, Lessee shall pay Lessor, without demand or invoice, an amount
          equal to Lessee's aggregate Activity Fees for the preceding calendar
          month, calculated by multiplying the total Approved Maximum Landing
          Weight for aircraft landed by Lessee at the Airport during the
          preceding

                                   -42-

<PAGE>


          calendar month by the Activity Fee rate for such Fiscal Year, computed
          in accordance with Article IIIB.1., and based on the Projection, as
          such projection may have been revised pursuant to paragraph 4 below.

          (c)  Lessee may net from the payments to be made to Lessor pursuant to
          paragraphs (a) and (b) above the amount of Midfield O&M Expenses
          actually paid by Lessee pursuant to Article VII.B. for the preceding
          calendar month.

     4.   ADJUSTMENT OF RENTALS AND ACTIVITY FEES:  Not later than the 150th day
of each Fiscal Year, Lessor shall furnish Lessee with a revised Projection (the
"Mid-Year Projection"), which shall reflect the most recently available
information with regard to the amounts actually incurred or realized during such
Fiscal Year for Bond Debt Service, O&M Expenses, and the Revenue Requirement, as
well as any changes in the number of useable square feet in the Midfield
Terminal and the Existing Terminal Facilities, together with the most recently
available information with regard to Terminal Charges and Activity Fees actually
received by Lessor.  Lessor shall give due consideration to any suggestions and
comments made by Lessee with respect to the Mid-Year Projection.  If the Mid-
Year Projection, as revised by Lessor after considering Lessor's suggestions and
comments, indicates that aggregate payments of Terminal Charges and Activity
Fees, at the then-existing rates would result in an overpayment or underpayment
of the aggregate amount required to be generated by Lessor through Terminal
Charges and Activity Fees, Lessor shall revise the Projection and adjust the
rates set forth therein for such Fiscal Year to conform to the Mid-Year
Projection.

                                   -43-

     5.   PRELIMINARY ANNUAL SETTLEMENT AND FINAL AUDIT:

          (a)  Within 60 days after the end of each Fiscal Year, Lessor will
          furnish Lessee with a preliminary report, containing a preliminary
          calculation, based on actual data, in accordance with this Agreement,
          of Terminal Charges and Activity Fees estimated to be chargeable to
          Lessee for the preceding Fiscal Year, and setting forth the amounts
          actually paid by Lessee for such period.  If such report indicates
          that the aggregate of such fees and charges actually paid by Lessee
          were greater than the aggregate amounts chargeable to Lessee, then
          within 90 days after the end of such Fiscal Year Lessor shall refund
          80% of any such estimated excess to Lessee.  If such report indicates
          that the aggregate of such fees and charges paid by Lessee were less
          than the amounts chargeable to Lessee, then within 90 days after the
          end of such Fiscal Year Lessee shall pay to Lessor 80% of the amount
          of any such estimated deficiency.  Interest shall accrue at a rate of
          7% per annum, and be payable by Lessee in cash, on any portion of any
          deficiency not paid by Lessee when due.  Interest shall accrue at a
          rate of 7% per annum, and be payable by Lessor, through a reduction in
          the amount of Lessor's administrative costs includible in O&M Expenses
          for the then Fiscal Year pursuant to Article IIIB.2.(a)(iii), on any
          portion of any excess not refunded to Lessee when due.

          (b)  By the 180th day of each Fiscal Year, Lessor shall furnish to
          Lessee a copy of an annual audit report prepared by a nationally
          recognized accounting firm, covering the operation of the Airport for
          the preceding Fiscal Year (the "Final Audit").  Lessor shall prepare a
          calculation, based

                                   -44-

<PAGE>


          on the Final Audit, in accordance with this Agreement, of all Terminal
          Charges and Activity Fees chargeable to Lessee for the preceding
          Fiscal Year, and setting forth the amounts actually paid by Lessee for
          such period, taking into account all payments and refunds pursuant to
          paragraph 5.(a) above.  If aggregate fees and charges actually paid by
          Lessee were greater than the aggregate amount chargeable, then within
          30 days after delivery of the Final Audit Lessor shall refund the
          amount of such overpayment to Lessee.  If aggregate fees or charges
          actually paid by Lessee were less than the aggregate amount chargeable
          to Lessee, then within 30 days after receipt of the Final Audit Lessee
          shall pay to Lessor the amount of any such deficiency.  The amount of
          Lessor's administrative costs includible in O&M Expenses for the then
          Fiscal Year shall be reduced by $50,000 for each month that delivery
          of the Final Audit to Lessee is delayed beyond the 180th day of such
          Fiscal Year.

          (c)  The payment by Lessee of any fees and charges hereunder and the
          acceptance by Lessor thereof for any Fiscal Year, shall not preclude
          either Lessee or Lessor from questioning, within a period of one (1)
          year from the date of receipt by Lessee of the Final Audit for such
          Fiscal Year, the accuracy of any report or statement on the basis of
          which such payment was made, or preclude Lessor from making any claim
          against Lessee for any additional amount payable by Lessee, or
          preclude Lessee from making any claim against Lessor for the return of
          any excess amount paid by Lessee.

G.   SUPPLEMENTAL CAPITAL COST PAYMENTS:  In addition to all other rentals and
charges payable hereunder by Lessee, Lessee shall pay the following annual Bond
Debt Service charges, which shall be billed on a monthly basis in advance each
month, in respect of certain projects that were constructed for the benefit of
Lessee in the Existing Terminal Facilities pursuant to the Basic Agreement:

     1.   $753,317.26 for the United Airlines relocation project;

     2.   $19,507.27 for the Concourse G elevator project;

     3.   $412,648.00 for the extension to Concourse C; and

Lessee will pay the above annual Bond Debt Service on that portion of the 1986
and 1993 General Airport Revenue Bonds even though the term of such debt service
obligation extends beyond the term of the lease of such temporary facilities. 
The foregoing notwithstanding, the parties acknowledge that (a) the aforesaid
amounts represent annual Bond Debt Service charges in effect on the execution
date of this Agreement and include amounts for 25% Paid in Coverage, and (b)
such amounts will be adjusted if and when coverage requirements change and/or
the Bonds to which such debt service charges relate are refinanced or refunded.

                        CONSTRUCTION, MAINTENANCE, REPAIR
                             AND OPERATION BY LESSEE
                             -----------------------
     Lessee may construct or install at its own expense any equipment,
improvements and facilities, and any additions thereto, upon all or any part of
the premises hereunder leased to Lessee for its exclusive use or preferential
use and may construct or install at its own expense, any equipment, improvements
and facilities authorized under Article I hereof upon any Airport property not
leased to Lessee for its exclusive use or preferential use at such locations as
may be approved by Lessor.  Plans and specifications of any proposed
construction or installation of improvements and facilities (including any
substantial alteration or addition thereto) shall be submitted to and receive
the prior approval of Lessor.  Lessor shall have the right to refuse approval of
such plans and specifications if the external appearance of such improvements
and facilities does not meet Lessor's reasonable requirements for substantial
uniformity of appearance of improvements and facilities on the Airport, or, if
the type or time of construction or installation, or the location thereof does
not meet Lessor's reasonable requirements for safe use of the Airport and
appurtenances by other authorized persons.  Lessor may, at its own cost, inspect
any such construction or installation.

     Lessee shall keep and maintain all premises hereunder leased to Lessee for
its exclusive use or preferential use and all such improvements and facilities
and additions thereto, whether constructed or installed by it upon premises
hereunder leased to it for its exclusive use or preferential use or upon Airport
property not leased to it for its exclusive use or preferential use, in good
condition and repair, reasonable wear and tear excepted, and damage by fire or
other casualty excepted.  Lessee shall not be liable for

                                   -47-

<PAGE>



the repair or restoration of damage to premises hereunder leased where such 
damage results from fire, structural defect, or other casualty for which 
Lessor has obtained and there is in effect adequate insurance protection 
covering such fire or other casualty.  No restriction shall be placed upon 
Lessee as to the architects, builders or contractors who may be employed by 
it in connection with any construction, installation, alteration, repair or 
maintenance of any such equipment, improvements, facilities and additions.

     Lessee shall keep such premises leased to Lessee for its exclusive use or
preferential use in a sanitary and sightly condition, and shall provide all
necessary janitor services with respect thereto.

     In the event that Lessee fails to perform for a period of thirty days after
written notice from Lessor so to do, any obligation required by this Article V
to be performed by Lessee at Lessee's cost, or fails to correct any construction
or installation by it of any equipment, improvements or facilities not completed
in accordance with the plans and specifications approved by Lessor within thirty
days of Lessor's notice to Lessee of a deviation from such plans and
specifications and request for appropriate changes in such construction and
installation, Lessor, upon the expiration of such thirty day period, may, but
shall not be obligated to, enter upon the premises involved and perform such
obligation of Lessee, charging Lessee the reasonable cost and expense thereof,
and Lessee agrees to pay Lessor such charge in addition to any other amounts
payable by Lessee hereunder; provided, however, that if Lessee's failure to
perform any such obligation adversely affects or endangers the health or safety
of the public or of employees of Lessor, and if Lessor so states in its
aforesaid notice to Lessee, Lessor may but shall not be obligated to perform
such obligation of Lessee at any time after the giving of such notice and
without awaiting the expiration of said thirty day period, and

                                   -48-

<PAGE>


charge to Lessee, and Lessee shall pay, as aforesaid, the reasonable cost and 
expense of such performance.  If Lessor shall perform any of Lessee's 
obligations in accordance with the provisions of this section, Lessor shall 
not be liable to Lessee for any loss of revenues to Lessee resulting from 
such performance.

                                   ARTICLE VI

                            RIGHT OF ENTRY BY LESSOR

     Lessor may enter upon the premises now or hereafter leased exclusively or
preferentially to Lessee hereunder at any reasonable time for any purpose
necessary, incidental to, or connected with the performance of its obligations
hereunder, in the exercise of its governmental functions, or in the event of any
emergency.

                                   ARTICLE VII

                   MAINTENANCE, OPERATION AND REPAIR BY LESSOR

     A.   Lessor shall operate, maintain and keep in good repair the areas and
facilities described in Article I hereof.  Lessor shall keep the Airport free
from obstruction, including, without limitation, the clearing and removal of
snow, vegetation, stones and other foreign matter from the runways, taxiways,
and loading areas and areas immediately adjacent to such runways, taxiways and
loading areas, as may be reasonably necessary for the safe, convenient and
proper use of the Airport by Lessee, and shall maintain and operate the Airport
in all respects in a manner at least equal to the highest standards or ratings
issued by the FAA for airports of similar size and character and in accordance
with all rules and regulations of the FAA.

     Lessor, at its cost, shall provide and supply adequate heat to and air
conditioning for the premises hereunder leased to Lessee for its exclusive use
or preferential use or for its use jointly or in common with others, and shall
provide reasonable illumination

                                   -49-

<PAGE>


and drinking water in the public and passenger space in the Midfield Terminal 
and the Existing Terminal Facilities and, except as otherwise provided 
herein, for the areas and facilities adjacent thereto respecting which Lessee 
is given a non-exclusive use hereunder. Lessor, at its cost, shall also 
provide adequate lighting for the vehicular parking spaces and adequate field 
lighting on and for the Airport, including, without limiting the generality 
hereof, boundary lights, landing lights, flood lights and beacons. Lessor, at 
its cost, shall also provide all janitor services and other cleaners 
necessary to keep the vehicular parking spaces and the landing field of the 
Airport at all times clean, neat, orderly, sanitary and presentable.

     Lessor shall provide adequate guards, at such times as may be required by
the circumstances, at all parts of the Airport which Lessee is entitled to use
jointly and in common with others.

     In the event that Lessor fails to perform for a period of thirty days after
written notice from Lessee so to do, any obligation required by this Article VII
to be performed by Lessor at Lessor's cost, Lessee, upon the expiration of such
thirty day period, may but shall not be obligated to perform such obligation of
Lessor and deduct the reasonable cost to Lessee of performing such obligation
from any rentals, fees or charges subsequently becoming due from Lessee to
Lessor under this Agreement; provided, however, that if Lessor's failure to
perform any such obligation adversely affects or endangers the health or safety
of Lessee or of any of any of its employees, agents, passengers, guests,
patrons, invitees, or its or their suppliers of materials or furnishers of
service or any of its or their property, and if Lessee so states in its
aforesaid notice to Lessor, Lessee may but shall not be obligated to perform
such obligation of Lessor at any time after the giving of said notice and
without awaiting the

                                   -50-

<PAGE>


expiration of said thirty day period, and Lessee may deduct its reasonable 
costs of performance thereof from any rentals, fees or charges as aforesaid.

     Lessor shall have the right to relocate at its own cost any equipment,
improvements and facilities constructed or installed by Lessee upon the Airport
property not leased hereunder to Lessee for its exclusive use or preferential
use pursuant to authorization therefor under Article I hereof; provided,
however, that such relocation shall be performed in such a manner and at such
times as are calculated to reduce to the minimum possible under the
circumstances any interference with Lessee's operations at the Airport, and that
the relocated equipment, improvements and facilities shall, when completed, be
commensurate with the equipment, improvements and facilities existing prior to
such relocation.

     B.   Notwithstanding the foregoing, Lessor hereby appoints Lessee as its
agent for the performance of, and Lessee agrees to and undertakes to perform,
the Assigned Operations and Maintenance Functions to be performed by Lessor
pursuant to this Article VII in, on and under the Midfield Terminal, pursuant to
the following agreements:

          1.   Lessee agrees to perform the Assigned Operations and Maintenance
Functions in a manner and to standards as are established for Lessor in this
Article VII.

          2.   In the event that Lessee fails to perform, for a period of 30
days after written notice from Lessor so to do, any obligation required by this
Article VII to be performed by Lessee at Lessee's cost, Lessor, upon the
expiration of such 30 day period, may, but shall not be obligated to, enter upon
the premises involved and perform such obligation of Lessee, provided, however,
that if Lessee's failure to perform any such obligation adversely affects, or
endangers the health or safety of the public or of

                                   -51-

<PAGE>


employees of Lessor, and if Lessor so states in its aforesaid notice to 
Lessee, Lessor may, but shall not be obligated to, perform such obligation of 
Lessee, at any time after the giving of such notice and without awaiting the 
expiration of said 30 day period.

          3.   As required by Article IIIF.1.(b)(vii) above, Lessee shall render
a detailed statement for reimbursement of the out of pocket costs incurred by
Lessee in connection with the Assigned Operations and Maintenance Functions
undertaken by Lessee under this Article VII within 20 days after the end of each
month, and Lessee shall be entitled to net such amounts against payments due
Lessor pursuant to Article IIIF.3. above.  Lessor shall be entitled to audit any
monthly statement of costs rendered by Lessee and Lessee will make available to
Lessor all of the records supporting such statements.  With respect to employees
of Lessee, Lessee shall be entitled to reimbursement for any out-of-pocket costs
incurred by it for salaries and benefits of Lessee's employees exclusively
assigned to the Assigned Operations and Maintenance Functions and who are based
at, and spend substantially all of their work time at, the Airport. The payments
made by Lessor to Lessee pursuant to this subsection shall be deemed to be
Midfield O&M Expenses.

          4.   In the performance of the functions undertaken pursuant to this
Article VII by contractor or third party forces engaged by Lessee, Lessee shall
require payment of wage rates and provision of benefits comparable to the wage
rates and benefits paid and provided to workers engaged in similar skilled
trades work for building maintenance projects in the Detroit Metropolitan Area.

     Lessor shall, directly or by arrangement with appropriate utility companies
or suppliers, supply Lessee with electrical current, gas, water, telephone and
sewerage facilities, and shall charge Lessee for such utility services at rates
not exceeding those which Lessee would have to pay if it established the same
demand and took the same quantity directly from such utility companies or
suppliers.  Lessor shall also supply electrical current to the ramp areas to be
used by Lessee in common with others and shall charge Lessee its appropriate
share of such electrical current at the rates hereinabove specified.

                                   ARTICLE IX

     Lessor shall, upon request of such persons or governmental or express
agencies make available reasonable and convenient space and facilities at the
Airport for the use of the United States Postal Service, or any person required
to use such space by regulations thereof, and for the use of an express agency
or agencies at a reasonable rental charge to such persons, governmental agency
and express agencies; and Lessor shall in like manner make available reasonable
and convenient space and facilities at the Airport for the use of the United
States Weather Bureau and FAA.

     Any other provision of this Agreement to the contrary notwithstanding,
Lessee shall have the right to operate directly or through a designee, assignee
or sub-lessee, private club facilities within such appropriate space leased to
it in the Midfield Terminal for such purposes, which club facilities shall be
authorized to serve food and beverages; provided, however, food and beverages
served in such private club facilities will be obtained by Lessee from the
Airport food concessionaire to the extent that same are available for purchase
from said Airport food concessionaire.

                              RULES AND REGULATIONS

     Lessor shall adopt and enforce reasonable rules and regulations and any
reasonable amendments thereto, with respect to the use of the Airport, which
shall provide for the safety of those using the Airport, and Lessee agrees to
observe and obey the same; provided, that such rules and regulations shall be
consistent with safety and with rules, regulations and orders of the FAA with
respect to aircraft operations at the Airport; and provided further, that such
rules and regulations shall not be inconsistent with the procedures prescribed
or approved from time to time by the FAA with respect to the operation of
Lessee's aircraft at the Airport.  Lessee shall be given notice of all
amendments to rules and regulations as are from time to time adopted by Lessor
and no such amendment shall be effective as to Lessee until thirty (30) days
after the date of such notice unless Lessor states in said notice that the
amendment is of an emergency nature, in which case the amendment shall be
immediately effective.

                       CONTROL OF RATES, FARES OR CHARGES

     Lessor shall have no control whatsoever over the rates or charges that
Lessee may prescribe for any of its services to, from, through or at the
Airport, or between the Airport and Lessee's ticket offices or other stopping
places in the City of Detroit or the County of Wayne, or elsewhere, nor shall
Lessor, except to the extent reasonably necessary to prevent physical damage or
injuries to persons or property at the Airport, in any manner whatsoever,
control the type, design, style, figuration, weight, allowable loads,
specifications or means of propulsion of, or use of space on, the aircraft
Lessee may operate to and from said Airport, or the point of origin or
destination of flights operated by Lessee to or from the Airport.

                                  ARTICLE XIII

                        DAMAGE OR DESTRUCTION OF PREMISES

     Notwithstanding the provisions of Article V as to maintenance and repair of
premises by Lessee, if any terminal at the Airport shall be partially damaged by
fire, the elements, the public enemy or other casualty but not rendered
untenantable, the same shall be repaired with due diligence by Lessor at its own
cost and expense.  In case any such terminal is so damaged or destroyed by fire,
the elements, the public enemy or other casualty, that it will or does become
untenantable, the said building shall be repaired, reconstructed or restored as
the case may be, with due diligence by Lessor at its own cost and expense, and
the rent payable hereunder with respect to said building shall be paid up to the
time of such damage or destruction and shall thenceforth abate until such time
as the said building shall be made tenantable.  Lessor shall maintain insurance
sufficient to enable it to fulfill its obligations under this Article.

     In the event that the Airport or any other premises herein leased are
rendered untenantable or unusable because of the condition thereof, there shall
be a reasonable and proportionate abatement of the rentals, fees and charges
provided for herein during the period that the same are so untenantable or
unusable.

                                   ARTICLE XIV

                             CANCELLATION BY LESSOR

     Lessor may cancel this Agreement by giving Lessee sixty (60) days advance
written notice to be served as hereinafter provided, upon or after the happening
of any one of the following events:

     (a)  The filing by Lessee of a voluntary petition in bankruptcy;

     (b)  The institution of proceedings in bankruptcy against Lessee and the
adjudication of Lessee as a bankrupt pursuant to such proceedings if such
adjudication shall remain unvacated or unstayed for a period of at least sixty
(60) days;

     (c)  The taking by a court of competent jurisdiction of Lessee and its

unstayed for a period of at least sixty (60) days;

     (d)  The appointment of a receiver of Lessee's assets if such appointment
by a court of competent jurisdiction shall remain unvacated or unstayed for a
period of at least sixty (60) days;

     (e)  The divestiture of Lessee's estate herein by other operation of law;

     (f)  The abandonment by Lessee of its conduct of Air Transportation at the
Airport;

                                   -56-

<PAGE>


     (g)  If the Lessee shall be prevented for a period of sixty (60) days
(after exhausting or abandoning all appeals) by any action of any governmental
authority, board, agency or officer having jurisdiction thereof from conducting
Air Transportation at the Airport unless it is so prevented from conducting Air
Transportation, either (1) by reason of the United States or any agency thereof
acting directly or indirectly, taking possession of and operating, in whole or
in substantial part, the premises and space leased or operated by the Lessee, or
premises required for the actual operation of Lessee's aircraft to and from the
Airport, or (2) if all or a substantial part of the premises and space leased by
the Lessee shall be acquired in the manner described in Article XXIV hereof;

     (h)  The default by Lessee in the performance of any covenant or agreement
herein required to be performed by Lessee and the failure of Lessee to remedy
such default for a period of sixty (60) days after receipt from Lessor of
written notice to remedy the same; provided, however, that no notice of
cancellation, as above provided, shall be of any force or effect if Lessee shall
have remedied the default prior to receipt of Lessor's notice of cancellation;

     Notwithstanding anything to the contrary herein contained, Lessor shall not
have the right to cancel, or give notice of cancellation of, this Agreement
solely by reason of Lessee's failure or refusal to pay any part of the rentals,
fees or charges provided for in this Agreement if, within sixty (60) days after
such failure or refusal, Lessee shall have given to Lessor a written notice
stating that Lessee in good faith predicates such failure or refusal upon either
or both of the following: (1) Any provision of this Agreement granting to Lessee
in specified events a reduction in or abatement of any rentals, fees or charges
payable by Lessee to Lessor hereunder, or (2) Any provision of this

                                   -57-

<PAGE>


Agreement authorizing Lessee in specified events to deduct from any such 
rentals, fees or charges, the reasonable cost to Lessee of performing any 
obligation or obligations required by this Agreement to be performed by 
Lessor.

     No waiver or default by Lessor of any of the terms, covenants or conditions
hereof to be performed, kept and observed by Lessee shall be construed to be or
act as a waiver of any subsequent default of any of the terms, covenants and
conditions herein contained to be performed, kept and observed by Lessee.  The
acceptance of rental by Lessor for any period or periods after a default of any
of the terms, covenants and conditions herein contained to be performed, kept
and observed by Lessee, shall not be deemed a waiver of any right on the part of
Lessor to cancel this Agreement for failure by Lessee to so perform, keep or
observe any of the terms, covenants or conditions of this Agreement.

                                   ARTICLE XV

                             CANCELLATION BY LESSEE

     Lessee, in addition to any other right of cancellation herein given to
Lessee or any other rights to which Lessee may be entitled by law or otherwise,
may, so long as Lessee is not in default in any payments to Lessor hereunder,
cancel this Agreement by giving Lessor sixty (60) days advance written notice to
be served as hereinafter provided, upon or after the happening of any one of the
following events:

     (a)  The failure or refusal, for reasons beyond the control of Lessee, of
the FAA, at any time during the term of this Agreement or any renewal thereof,
to permit Lessee to operate into or from the Airport with any type of aircraft
which Lessee may be licensed to operate into or from other airports of like size
and character and which Lessee may reasonably desire to operate into or from the
Airport;

                                   -58-

<PAGE>


     (b)  Issuance by any court of competent jurisdiction of an injunction in
any way substantially preventing or restraining the use of the Airport or any
part thereof necessary for Lessee's operations, and the remaining in force of
such injunction for a period of at least sixty (60) days at least after Lessor
has exhausted or abandoned all appeals;

     (c)  The inability of Lessee due to circumstances beyond its control to
use, for a period in excess of ninety (90) days, the Airport or to exercise any
rights and privileges granted to Lessee hereunder and necessary to its
operations because of any law or ordinance, or because of any order, rule,
regulation or other action or any non-action of the FAA or any other
governmental authority, or, because of earthquake, other casualty (excepting
fire) or because of Acts of God or the public enemy;

     (d)  The default by Lessor in the performance of any covenant or agreement
herein required to be performed by Lessor and the failure of Lessor to remedy
such default for a period of ninety (90) days after receipt from Lessee of
written notice to remedy the same; provided, however, that no notice of
cancellation, as above provided, shall be of any force or effect if Lessor shall
have remedied the default prior to receipt of Lessee's notice of cancellation.

     Lessee's performance of all or any part of this Agreement for or during any
period or periods after a default of any of the terms, covenants and conditions
herein contained to be performed, kept and observed by Lessor, shall not be
deemed a waiver of any right on the part of Lessee to cancel this Agreement for
failure by Lessor so to perform, keep or otherwise observe any of the terms,
covenants, or conditions hereof to be performed, kept and observed by Lessor, or
be construed to be or act as a waiver by Lessee of any

                                   -59-

<PAGE>


subsequent default of any of the terms, covenants and conditions herein 
contained to be performed, kept and observed by Lessor.

                                   ARTICLE XVI

                            SUSPENSION AND ABATEMENT

     In the event that Lessor's operation of the Airport or Lessee's operation
at the Airport should be restricted substantially by action of any court of
competent jurisdiction or by action of the federal government or any agency
thereof, or by action of the State of Michigan or any agency thereof, then
either party hereto shall have the right, upon written notice to the other, to a
suspension of this Agreement and an abatement of a just proportion of the
services and facilities to be afforded hereunder, or a just proportion of the
payments to become due hereunder, from the time of such notice until such
restriction shall have been remedied and normal operations restored. 
Ascertainment of all matters under this Article shall be determined by agreement
or by arbitration as provided in Article XVII hereof.

                                  ARTICLE XVII

                                   ARBITRATION

     If any controversy or claim should arise out of, under, or relating to, the
provisions of Articles III or XVI of this Agreement, then either party may by
notice in writing to the other, submit the controversy or claim to arbitration. 
The party desiring such arbitration shall give written notice to that effect to
the other party, specifying in said notice the name and address of the person
designated to act as arbitrator on its behalf.  Within fifteen (15) days after
the service of such notice, the other party shall give written notice to the
first party specifying the name and address of the person designated to act as
arbitrator on its behalf.  The arbitrators thus appointed shall

                                   -60-

<PAGE>



appoint a third disinterested person of recognized competence in such field, 
and such three arbitrators shall as promptly as possible determine the 
controversy or claim.

     If the two arbitrators appointed by the parties shall be unable to agree
upon the appointment of a third arbitrator within fifteen (15) days after the
appointment of the second arbitrator, then within fifteen (15) days thereafter
either of the parties upon written notice to the other party, on behalf of both,
may request the appointment of a disinterested person of recognized competence
in the field involved as the third arbitrator by the then chief judge of the
United States District Court for the Eastern District of Michigan, Southern

existing or future agreement between the Lessor and the United States, relative
to the operation or maintenance of the Airport, the execution of which has been
or may be required as a condition precedent to the expenditure of Federal funds
for the development of the Airport.

exercise of rights granted and/or the performance of obligations assumed 
under this Agreement.

     C.   AFFIRMATIVE ACTION PROGRAM: In addition to the foregoing, the parties
hereto agree to carry out and be subject to the provisions of Addendum 1,
entitled "NON-DISCRIMINATION AFFIRMATIVE ACTION AND SET ASIDE PROGRAMS FOR WAYNE

     D.   DISADVANTAGED BUSINESS ENTERPRISE:  Lessee agrees to comply with the
following policy and requirements of the Department of Transportation:

          1.   POLICY.  It is the policy of the Department of Transportation
          that disadvantaged business enterprises as defined in 49 CFR Part 23
          shall have the maximum opportunity to participate in the performance
          of contracts financed in whole or in part with Federal funds under
          this Agreement.  Consequently the disadvantaged business enterprise
          requirements of 49 CFR Part 23 apply to this Agreement.

          2.   DBE OBLIGATION.  (i)  The recipient or its contractor agrees to
          ensure that disadvantaged business enterprises as defined in 49 CFR
          Part 23 have the maximum opportunity to participate in the performance
          of contracts and subcontracts financed in whole or in part with
          Federal funds provided under this Agreement.  In this regard all
          recipients or contractors shall take all necessary and reasonable
          steps in accordance with 49 CFR Part 23 to ensure that disadvantaged
          business enterprises have the maximum opportunity to compete for and
          perform contracts.  Recipients and their contractors shall not
          discriminate on the basis of

                                   -78-

<PAGE>


          race, color, national origin, or sex in the award and performance of
          Department of Transportation-assisted contracts.

               Failure of a contractor or subcontractor to carry out the
          requirements set forth in paragraph 23.43(a) of 49 CFR Part 23 shall
          constitute a breach of contract and, after notification of the
          Department of Transportation, may result in termination of the
          Agreement or contract by the recipient or such remedy as the recipient
          deems appropriate.

               The definitions set forth in paragraph 23.5 of 49 CFR Part 23
          shall apply to the foregoing statements concerning disadvantaged
          business enterprises.

                                  ARTICLE XXXIV

                             CONFORMITY OF AGREEMENT

     In the event that Lessor shall hereafter enter into any lease, contract or
agreement with any other scheduled air transport operator, with respect to the
use of the Airport or terminal facilities, containing more favorable terms than
this Agreement, or shall hereafter grant to any other scheduled air transport
operator, rights or privileges with respect thereto which are not accorded to
Lessee hereunder, then the same rights, privileges and more favorable terms
shall be concurrently and automatically made available to Lessee.

                    Protocol for Use of International Gates
                               Midfield Terminal
 
The international gates, together with related holdrooms, jetbridges, ramp
access and baggage facilities, will be made available in accordance with the
following priority of use:

1.  Regularly scheduled international airline service, with existing service
    having precedence over new service;

2.  International charter arrivals, if and for so long as the Federal government
    prohibits FIS operations at the Berry International Terminal;

3.  Regularly scheduled Northwest domestic service;

4.  Delayed international charter arrivals when the expected delay for the
    flight to use the Berry International Terminal will exceed 90 minutes and
    use of a Midfield Terminal FIS gate will not interfere with the scheduled
    international or domestic use of the gate.

5.  Non-scheduled or irregular charter arrivals and the use of a Midfield
    Terminal FIS gate will not interfere with the scheduled international or
    domestic use of that gate.

In making the determination of whether an international non-stop passenger
flight to the Airport is a regularly scheduled flight or a charter operation for
purposes of this protocol, the Airport will apply the following criteria:

1.  Does the international operation generally have passengers connecting at the
    Airport on-line, inter-line, or via code share, and the operational need for
    connecting facilities?

2.  Is the carrier operating the flight a signatory under the airport agreement
    for the Airport?

3.  Does the carrier operating the flight hold all necessary government 
    approvals to operate international regularly scheduled service?

4.  Is the carrier's international service primarily scheduled on a year-round
    basis or does it primarily offer seasonal services to different locations?


<PAGE>

5.  Are the carrier's schedules published each month in the Official Airline
    Guide and displayed in computer reservation systems? Are the fares regularly
    published by the Airline Tariff Publishing Company?

6.  Does the carrier providing the service provide reservation services and
    create PNR (passenger name records) for the flights with its own employees?

International operations that meet these criteria overall shall be considered
international regularly scheduled flights for purposes of this protocol.
However, the failure to meet any one or more criteria shall not necessarily
preclude the operation from being considered an international regularly
scheduled flight. The Airport's goal of optimizing overall airport operating
efficiency shall be an important consideration.

Exhibit E
ALLOCATION OF BOND DEBT SERVICE
Detroit Metropolitan Wayne County Airport
(All figures in thousands, except where noted)
 
    This exhibit details the methodology for allocating Bond Debt Service to
various components of the Airport. This is required when terminal rental rates
transition to a compensatory-based approach in FY2009. These steps should be
followed for each bond series and issuance. An example is provided to illustrate
the allocation methodology.
 
STEP 1:  IDENTIFY NET FINANCEABLE COSTS FROM EACH BOND ISSUANCE
 
    The first step is determine the net financeable project costs which
constitute each bond issuance. Net financeable costs should be grouped into one
of the following categories: Midfield Domestic Terminal, Midfield International
Terminal, Midfield Overhead, Existing Terminals, and all Airfield projects. The
following projects, related to the construction of the Midfield Terminal
Complex, are considered Midfield Overhead; tunnels and walkways, terminal
arrival and departure roadways, powerplant and utilities, and relocated
facilities.
 
                              EXAMPLE: 1998 BONDS
 
                      1998 BONDS
                      Bond Debt Service                   $11,400

                      NET FINANCEABLE COSTS
                      Midfield-Domestic                   $73,400
                      Midfield-International                7,600
                      Midfield-Overhead                    10,700
                      Existing Terminals                    1,000
                      Airfield                              3,400
                                                          -------
                          Total Costs                     $96,100

STEP 2:  ALLOCATE MIDFIELD OVERHEAD CAPITAL COSTS
 
    The next step is to allocate the Midfield Overhead capital costs to either
the Midfield Domestic Terminal or the Midfield International Terminal. The
allocation of Midfield Overhead capital costs will be based on each terminal
(Midfield Domestic and International) share of net financeable costs in the bond
issuance.
 
                              EXAMPLE: 1998 BONDS
 
            NET FINANCEABLE COSTS                     $ Share  % Share
                                                      -------  -------
            Midfield-Domestic                          $73,400   90.6%
            Midfield-International                       7,600    9.4%

            ALLOCATION OF MIDFIELD OVERHEAD COSTS
            Midfield-Overhead                          $10,700
               TO:
            Midfield-Domestic                           $9,696
            Midfield-International                      $1,004

STEP 3:  DETERMINE PERCENTAGE SHARE OF NET FINANCEABLE COSTS
 
    The third step is to determine the percentage share of net financeable costs
for each category. This share will be used to allocate Bond Debt Service. After
Step 2, allocation of Midfield Overhead costs, there will be four remaining
categories--Midfield Domestic terminal, Midfield International terminal,
Existing Terminals, and all Airport projects.

                              EXAMPLE: 1998 BONDS
 
            NET FINANCEABLE COSTS
            Midfield-Domestic                         $73,400
            From Midfield-Overhead                      9,696
                                                      -------
            Total Midfield-Domestic                   $83,096    86.47%

            Midfield-International                    $ 7,600
            From Midfield-Overhead                      1,004
                                                      -------
               Total Midfield-International           $ 8,604     8.95%

            Existing Terminals                        $ 1,000     1.04%

            Airfield                                  $ 3,400     3.54%
                                                      -------   -------
                Total Costs                           $96,100   100.00%
 
STEP 4:  ALLOCATE BOND DEBT SERVICE
 
    The last step is to allocate Bond Debt Service to one of the four 
categories. The allocation of Bond Debt Service is based on the percentage 
share of net financeable costs calculated in Step 3. The allocated Bond Debt 
Service will be incorporated into the compensatory-based terminal rental 
rates.
 
                              EXAMPLE: 1998 BONDS
 
            1998 BONDS                        $ Share  % Share
                                              -------  -------
            Bond Debt Service                 $11,400

            BOND DEBT SERVICE ALLOCATION
            Midfield-Domestic                 $9,858    86.47%
            Midfield-International             1,020     8.95%
            Existing Terminals                   119     1.04%
            Airfield                             403     3.54%
                                              -------  -------

   O&M, etc.)
</TABLE>

STEP 1

    O&M Expenses are allocated to Midfield and Existing Complexes. The 
    allocated O&M Expenses will be directly related to the operation and 
    maintenance of either the Domestic Midfield Terminal, the International 
    Midfield Terminal, or the Existing Complex (Smith, Davey, and Berry) 
    Terminals. Other Airport O&M Expenses, like airfield and other indirect 
    operating costs will flow to the activity fee.

STEP 2

    Allocated O&M Expenses for each terminal (Midfield Domestic, Midfield 
    International and Existing Terminals) are then divided by the total 
    useable space of each respective terminal. This generates an O&M Expense
    per square foot which air carriers will begin paying in FY2009.

STEP 3

    Indirect O&M Expenses will flow to the activity fee. Signatory Airlines 
    will pay these indirect O&M Expenses in proportion to their landed weight
    at the Airport.

fiscal year of the Company shall not be more than 250,000 Shares.  These Shares
may consist in whole or in part of authorized and unissued Shares, or of
treasury Shares.  No fractional Shares shall be issued under the Plan; however,
cash may be paid in lieu of any fractional Shares in settlements of Awards under
the Plan.  For purposes of determining the number of Shares remaining available
for issuance under the Plan:

          (a)  The grant of an Award shall reduce the authorized pool of Shares
by the number of Shares subject to such Award while such Award is outstanding,
except to the extent that such 

<PAGE>

an Award is in tandem with another Award covering the same or fewer Shares 
which has already been taken into account in determining the authorized pool 
of Shares.

          (b)  Shares covered by SARs that are not issued upon the exercise of
such SAR shall increase the authorized pool of Shares.

          (c)  To the extent that an Award (other than an SAR) is settled in
cash or any form other than in Shares, the authorized pool of Shares shall be
increased by the appropriate number of Shares represented by such settlement of
the Award, as determined at the sole discretion of the Committee (subject to the
limitation set forth in Section 4.2).


     4.2  LAPSED AWARDS.  If any Award (other than an Award of Shares) granted
under the Plan is canceled, terminates, expires or lapses for any reason, any
Shares subject to such Award shall increase the authorized pool of Shares;
provided, however, that to the extent that such Award was granted in tandem with
another Award, any Shares issued pursuant to the exercise or settlement of such
other Award shall not increase the authorized pool of Shares.


     4.3  EFFECT OF ACQUISITION.  Any Awards granted by the Company in
substitution for awards or rights issued by a company whose shares or assets are
acquired by the Company or a Subsidiary shall not reduce the number of Shares
available for grant under the Plan.


                                       6

     4.4  ADJUSTMENTS IN AUTHORIZED SHARES.  Subject to Article 7, in the event
of any merger, reorganization, consolidation, recapitalization, separation,
spin-off, liquidation, stock dividend, split-up, Share combination or other
change in the corporate or capital structure of the Company affecting the
Shares, the Committee shall adjust the number and class of Shares which may be
delivered under the Plan, and the number and class of and/or price of Shares
subject to outstanding Awards granted under the Plan, in the manner determined
by the Committee in its sole discretion to prevent dilution or enlargement of
rights; provided that the number of Shares subject to any Award shall always be
a whole number.


     4.5  COMMITTEE DETERMINATION.  In determining the number of Shares
available for issuance under the Plan as contemplated by this Article 4, the
Committee shall interpret and apply the provisions of this Article so as to
permit the Plan to comply with Rule 16b-3 under the Exchange Act, or any
successor rule thereto.


ARTICLE 5.  PARTICIPATION


     5.1  SELECTION OF PARTICIPANTS.  Subject to the provisions of the Plan, the
Committee may from time to time select, from all Eligible Employees, those to
whom Awards shall be granted and shall determine the nature and amount of each
Award.  No Eligible Employee shall have the right to receive an Award under the
Plan, or, if selected to receive an Award, the right to continue to receive
Awards.  Further, no Participant shall have any rights, 

                                       7


<PAGE>

by reason of the grant of any Award under the Plan to continued employment by 
the Company or any Subsidiary.  There is no obligation for uniformity of 
treatment of Participants under the Plan.

     5.2  AWARD AGREEMENT.  Each Award granted under the Plan shall be evidenced
by an Award Agreement that shall specify the terms, conditions, limitations and
such other provisions applicable to the Award as the Committee shall determine.


ARTICLE 6.  AWARDS


     Awards may be granted by the Committee to Eligible Employees at any time,
and from time to time prior to the Termination Date, as the Committee shall
determine.  The Committee shall have complete discretion in determining the
number of Awards to grant (subject to the Share limitations set forth in Section
4.1) and, consistent with the provisions of the Plan, the terms, conditions and
limitations pertaining to such Awards.


                                       8

<PAGE>

     6.1 STOCK OPTIONS.

          a.   OPTION PRICE   

          The option price for a Stock Option shall be determined by the
     Committee; provided that Incentive Stock Options may not be granted at a
     price less than one hundred percent (100%) of the Fair Market Value of a
     Share on the date the Incentive Stock Option is granted.

          b.   PERIOD OF EXERCISE

          A Stock Option may be exercised at such times as may be specified in
     an Award Agreement, in whole or in installments, which may be cumulative
     and shall expire at such time as the Committee shall determine at the time
     of grant; provided that no Stock Option shall be exercisable later than ten
     (10) years after the date granted.  The Committee may make provision for
     exercisability in the event of death, Disability, Retirement or other
     termination of employment.  The Committee may also amend any Stock Option
     to accelerate the dates after which the Option may be exercised in whole or
     in part.

          c.   ADDITIONAL PROVISIONS FOR ISOS

          No ISO shall be granted to any employee who, at the time the Stock
     Option is granted, owns (directly, or within the meaning of section 424(d)
     of the Code) more than ten percent of the total combined voting power of
     all classes of stock of the Company or of any Subsidiary, unless (a) the
     option price under such Stock Option is at least 110 percent of the Fair
     Market Value of a share of Stock on the date the 


                                       9

<PAGE>

     Stock Option is granted and (b) the expiration date of such Stock Option 
     is a date not later than the day preceding the fifth anniversary of the 
     date on which the Stock Option is granted.

          d.   METHOD OF EXERCISE

          A Stock Option, or portion thereof, shall be exercised by delivery of
     a written notice of exercise to the Company and payment of the full price
     of the Shares being purchased pursuant to the Option.  An optionee may
     exercise a Stock Option with respect to less than the full number of shares
     for which the Option may then be exercised, but an optionee must exercise
     the Stock Option in full shares of Stock.  The price of Stock purchased
     pursuant to a Stock Option, or portion thereof, may be paid:

          (i)  in United States dollars in cash or by check, bank draft or money
     order payable to the order of the Company,

          (ii)  through the delivery of shares of Stock with an aggregate Fair
     Market Value on the date of exercise equal to the option price,

          (iii)  to the extent authorized by the Committee, by delivery of
     irrevocable instructions to a financial institution to deliver promptly to
     the Company the portion of sale or loan proceeds sufficient to pay the
     option price,

          (iv)  to the extent authorized by the Committee, by the withholding of
     Shares otherwise issuable on exercise with an aggregate Fair Market Value
     on the date of exercise equal to the Option Price.


                                       10


<PAGE>

          (v)  by any combination of the above methods of payment or by any
     other means which the Committee determines to be consistent with the Plan's
     purpose and applicable law.

     6.2 STOCK APPRECIATION RIGHTS. (a)  SARs may be granted at a price
determined by the Committee, and may be granted in tandem with a Stock Option,
such that the exercise of the SAR or related Stock Option will result in a
forfeiture of the right to exercise the related Stock Option for an equivalent
number of shares, or independently of any Stock Option.

          (b)  An SAR may be exercised at such times as may be specified in an
Award Agreement, in whole or in installments, which may be cumulative and shall
expire at such time as the Committee shall determine at the time of grant;
provided that no SAR shall be exercisable later than ten (10) years after the
date granted.  The Committee may amend any SAR to accelerate the dates after
which the SAR may be executed in whole or in part.

          (c)  SARs shall be exercised by the delivery of a written notice of
exercise to the Company setting forth the number of Shares with respect to which
the SAR is to be exercised.


     6.3 RESTRICTED STOCK.  Restricted stock may be granted alone or in
conjunction with other Awards under the Plan and may be conditioned upon
continued employment for a specified period, the attainment of specific
performance goals or such other factors as the Committee may determine.  In
making an Award of 


                                       11


<PAGE>

Restricted Stock, the Committee will determine the restrictions that 
will apply, the period during which the Stock is subject to such 
restrictions, and the price, if any, payable by a recipient.  The 
Committee may amend any Award of Restricted Stock to accelerate the 
dates after which such Award may be executed in whole or in part. 

     6.4 OTHER STOCK BASED AWARDS. (a)  The Committee shall have complete
discretion in determining the number of Shares subject to Other Stock Based
Awards the consideration for such Awards and the terms, conditions and
limitations pertaining to same including, without limitation, restrictions based
upon the achievement of specific business objectives, tenure, and other
measurements of individual or business performance, and/or restrictions under
applicable federal or state securities laws, and conditions under which such
Awards will lapse.

          (b)  Payment of Other Stock Based Awards may be in the form of cash,
shares, other Awards, or in such combinations thereof as the Committee shall
determine at the time of grant, and with such restrictions as it may impose. 
Payment may be made in a lump sum or in installments as prescribed by the
Committee.  The Committee may also require or permit Participants to elect to
defer the issuance of Shares or the settlement of Awards in cash under such
rules and procedures as it may establish under the Plan.  The Committee may also
provide that deferred settlements include the payment or crediting of interest
on the deferred 


                                       12


<PAGE>

amounts or the payment or crediting of dividend equivalents on deferred 
amounts denominated in Shares.

          (c)  The Committee may, at its sole discretion, direct the Company to
issue Shares subject to such restrictive legends and/or stop transfer
instructions as the Committee deems appropriate.


ARTICLE 7.  AMENDMENT, MODIFICATION AND TERMINATION.


     7.1 The Board may at any time, or from time to time, suspend or terminate
the Plan in whole or in part or amend it in such respects as the Board may deem
appropriate, provided, however, that no such amendment shall be made, which
would, without approval of the shareholders (except as provided in Section 7.4);

          a.  materially modify the eligibility requirements for receiving
Awards;

          b.  increase the total number of shares of Common Stock which may be
issued pursuant to Awards, except as is provided for in accordance with Article
4 of the Plan;

          c.  extend the period during which Awards may be granted; or

          d.  materially increase in any other way the benefits accruing to
Participants.


                                       13


<PAGE>

     7.2 No amendment, suspension or termination of this Plan or any Award
shall, without the Participant's consent, alter or impair any of the rights or
obligations under any Award theretofore granted to an Participant under the
Plan.


     7.3 The Board may amend this Plan, subject to the limitations cited above,
in such manner as it deems necessary to permit the granting of Awards meeting
the requirements of future amendments to the Code or regulations promulgated
thereunder.


     7.4 If and to the extent the provisions of Rule 16b-3 (as in effect on the
date of adoption of the Plan by the Board) under the Exchange Act permit the
amendment of stock incentive plans without compliance with one or more of the
stockholder approval requirements presently set forth in Section 7.1, then and
to that extent the restrictions on the ability of the Board to amend the Plan
set forth in Section 7.1 hereof shall terminate and the Board shall thereafter
be empowered to amend the Plan without regard to such restrictions.


ARTICLE 8.  WITHHOLDING


     8.1 TAX WITHHOLDING.  The Company shall have the power and the right to
deduct or withhold, or require a Participant to remit to the Company, an amount
in cash sufficient to satisfy federal, state and local taxes required by law to
be withheld in connection with a grant, exercise or payment made under or as a
result of the Plan.


                                       14

<PAGE>

     8.2 SHARE WITHHOLDING.  The Committee may require one or more classes of
Participants to satisfy the withholding requirement, in whole or in part, by
having the Company withhold Shares having a Fair Market Value, on the date the
tax is to be determined, equal to the amount of withholding which is required by
law.  Alternatively, the Committee may allow a Participant to elect Share
withholding for tax purposes subject to such terms and conditions as the
Committee shall establish.


ARTICLE 9.  TRANSFERABILITY


     No Award granted under the Plan may be sold, transferred, pledged, assigned
or otherwise alienated or hypothecated, other than by will or by the laws of
descent and distribution.  Further, all Awards granted to a Participant under
the Plan shall be exercisable during the Participant's lifetime only by the
Participant.  Notwithstanding the foregoing, the designation of a beneficiary by
a Participant does not constitute a transfer.


ARTICLE 10.  UNFUNDED PLAN


     10.1 UNFUNDED PLAN.  The Plan shall be unfunded and the Company shall not
be required to segregate any assets that may at any time be represented by
Awards under the Plan.  Any liability of the Company to any person with respect
to any Award under the Plan shall be based solely upon any contractual
obligations that may be effected pursuant to the Plan.  No such obligation of
the Company shall be deemed to be secured by any pledge of, or other encumbrance
on, any property or assets of the Company.


                                       16


<PAGE>

ARTICLE 11.  SUCCESSORS.


     11.1 SUCCESSORS.  All obligations of the Company under the Plan with
respect to Awards granted hereunder shall be binding on any successor to the
Company, whether the existence of such successor is the result of a direct or
indirect purchase, merger, consolidation or otherwise, of all or substantially
all of the substantially all of the business and/or assets of the Company.


ARTICLE 12.  SECURITIES LAW COMPLIANCE


     12.1 SECURITIES LAW COMPLIANCE.  The Plan is intended to comply with all
applicable conditions of Rule 16b-3 or any successor rule thereto under the
Exchange Act.  To the extent any provision of the Plan or action by the
Committee fails to so comply, it shall be deemed null and void, to the extent
permitted by law and deemed advisable by the Committee.  Further, each Award
shall be subject to the requirement that, if at any time the Committee shall
determine, in its sole discretion, that the listing, registration or
qualification of any Award under the Plan upon any securities exchange or under
any state or federal law, or the consent or approval of any government
regulatory body, is necessary or desirable as a condition of, or in connection
with, the granting of such Award or the grant or settlement thereof, such Award
may not be exercised or settled in whole or in part unless such listing,
registration, qualification, consent or approval shall have been effected or
obtained free of any conditions not acceptable to the Committee.

                                       17


<PAGE>

ARTICLE 13.  REQUIREMENTS OF LAW


     13.1 REQUIREMENTS OF LAW.  The granting of Awards and the issuance of
Shares under the Plan shall be subject to all applicable laws, rules and
regulations and to such approvals by any governmental agencies or national
securities exchanges as may be required.


     13.2 SEVERABILITY.  In the event any provision of the Plan shall be held
illegal or invalid for any reason, the illegality or invalidity shall not affect
the remaining parts of the Plan, and the Plan shall be construed and enforced as
if the illegal or invalid provision had not been included.


     13.3 GOVERNING LAW.  To the extent not preempted by federal law, the Plan
and all Award Agreements shall be construed in accordance with and governed by
the laws of the State of Minnesota.


ARTICLE 14.  MISCELLANEOUS PROVISIONS


     14.1 PLAN DOES NOT CONFER EMPLOYMENT OR STOCKHOLDER RIGHTS.  The right of
the Company to terminate (whether by dismissal, discharge, retirement or
otherwise) the Optionee's employment with it at any time at will, or as
otherwise provided by any agreement between the Company and the Optionee, is
specifically reserved.  Neither the Optionee nor any person entitled to exercise
the Optionee's rights in the event of the Optionee's death shall have any of the
rights of a stockholder with respect to the shares subject to each Option,
except to the extent that, 


                                       18


<PAGE>

and until, such shares shall have been issued upon the exercise of each 
Option.

     14.2 PLAN EXPENSES.  Any expenses of administering this Plan shall be borne
by the Company.


     14.3 USE OF EXERCISE PROCEEDS.  Payments received from Optionees upon the
exercise of Options shall be used for the general corporate purposes of the
Company, except that any stock received or withheld in payment may be retired,
or retained in the Company's treasury and reissued.
