        B.    LEASE OF SPACE:    

        1.    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 space in the Existing
Terminal Facilities identified on Exhibit B attached hereto (hereinafter
referred to as "Lessee's Existing Terminal Space"). As promptly as possible
after the commencement of Lessee's Air Transportation business in the South
Terminal, but in any event not more than 60 days after such commencement, Lessee
shall vacate Lessee's Existing Terminal Space, and the lease hereunder of
Lessee's Existing Terminal Space shall terminate upon the earlier of 90 days
after such commencement and 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 South 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

3

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

demolition of the space in the Existing Terminal Facilities scheduled for
demolition as part of the Northwest Demolition Project (hereinafter referred to
as "Existing Terminal Space To Be Demolished").

        2.    PREFERENTIAL USE PREMISES.    

        (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 South Terminal
consisting of the Preferential South Terminal Space identified on Exhibit C
attached hereto (hereinafter referred to as "Lessee's Preferential South
Terminal Space"). Lessee shall have the right to permit its code share partners
and commuter carriers to have access to Lessee's Preferential South Terminal
Space.

        (b)  Lessee's Preferential South 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 such
space, the preferential right to use the aircraft parking positions adjacent to
such space, as shown on Exhibit C, for the parking of aircraft and support
vehicles and the loading and unloading of passengers and cargo.

        (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 South
Terminal, which need cannot be met by use of then unleased premises, if any, in
the South Terminal or the North Terminal, 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 designated portion of Lessee's Preferential South
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, but excluding Lessee's
member-only airline clubs within Lessee's Preferential South Terminal 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.

4

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

        (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 South
Terminal Space (excluding Lessee's member-only airline clubs), 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 which 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;

        (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 passenger loading bridges used or owned by
Lessee and other portions of Lessee's Preferential South Terminal Space
(excluding Lessee's member-only airline clubs) 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 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

5

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

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 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
South 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.

        (G)  The foregoing provisions of this Article
IB.2.(b)(iii) notwithstanding, Lessor may grant a requesting airline the right
to temporarily use a designated portion of Lessee's Preferential South Terminal
Space (excluding Lessee's member-only airline clubs) 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 South Terminal Space or
other related facilities by other airlines scheduled by Lessor pursuant to this
Article IB.2., 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 South Terminal Space or other
related facilities, unless caused by the negligence of Lessee, its employees or
agents.

        3.    SHARED USE PREMISES.    At such time as such space is available
for beneficial occupancy, Lessor grants to Lessee, its employees, agents,
guests, patrons and invitees, the shared use, along with all other air carriers
operating Air Transportation businesses in the South Terminal to whom such
shared use has been granted, of space, improvements and facilities in the South
Terminal consisting of the Shared Use South Terminal Space identified on
Exhibit C attached hereto. That portion of the Shared Use South Terminal Space
consisting of the international gates in the South Terminal, together with
related holdrooms, jetbridges, ramp access and baggage facilities, shall be
allocated for use by the users thereof in accordance with the priorities
described in Exhibit D 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 terminals at the Airport, and all additional public space which may
thereafter be made available therein and in any additions thereto, including,
without limiting the generality thereof, common areas for passenger movement,
concessions areas, entrances, exits, lobbies, public waiting areas, public
restrooms, hallways and other premises for other public and passenger
convenience.

        D.    PARKING SPACE:    Vehicular parking spaces shall be provided near
the terminal from which Lessee is operating (adequate in Lessor's judgment,
considering the number of vehicles and traffic to be accommodated) 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, 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.

6

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

        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, together with the right to install thereon underground fuel storage
tanks, pumps, piping, and appurtenances for the storage of aviation fuel; the
location 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 of this Agreement, will be attached to this Agreement as an
exhibit.

ARTICLE II

TERM

        Except as expressly provided otherwise in Article IB.1., Lessee shall
have full authority to use the premises and facilities and to exercise the
rights, licenses and privileges set forth in Article I hereof for a term
beginning on the Date of Beneficial Occupancy of the South Terminal and ending
on September 30, 2032.

ARTICLE III

RENTALS AND FEES

        Lessee agrees to pay to Lessor for the use of the premises, facilities,
rights, licenses, services and privileges granted hereunder, the following
rentals, fees and charges, all payable in monthly installments in accordance
with paragraph G. below. In the event that the commencement or termination of
the term with respect to any of the particular premises, facilities, rights,
licenses, services or privileges as herein provided falls on any date other than
the first or last day of a calendar month, the applicable rentals, fees and
charges for that month shall be paid for said month pro rata according to the
number of days in that month during which the particular premises, facilities,
rights, licenses, services or privileges were enjoyed. No rentals, fees, charges
or tolls imposed by Lessor other than those specifically provided in this
Agreement are payable by Lessee for the use of or access to the Airport,
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
transportation to, from and on the Airport or from any concessionaire at the
Airport in accordance with the terms of a contract with Lessor for the operation
of such concession; and provided, further, that Lessor reserves the right to
impose and use PFCs; and provided, further, that the foregoing shall not
preclude Lessor from imposing or levying any permit or license fee not
inconsistent with the rights and privileges granted to Lessee hereunder.

        A.    TERMINAL RENTALS AND TERMINAL USE CHARGES:    During the term
hereof, Lessee shall pay to Lessor the following Terminal Charges:

        1.    EXISTING TERMINAL SPACE:    For so long as Lessee shall retain any
Lessee's Existing Terminal Space pursuant to Article IB.1., Lessee shall be
obligated to pay terminal rentals for such premises equal to that which would
have been applicable for such space under the First Amended and Restated Airport
Agreement, immediately prior to the effectiveness of this Agreement.

        2.    PREFERENTIAL USE PREMISES:

Year 2008, Lessee shall pay an amount equal to the product of the total number
of square feet of Lessee's

7

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. Except as set forth in the next sentence, the annual
administrative charges shall pay for all services provided directly or

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

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

        (B)  Deposits shall be made into the 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

pursuant to item (4) of the definition thereof in Article IIIB.1., (II) up to
$2.5 million of revenue received by Lessor each Fiscal Year that is attributable
to an automated vehicle identification program for the entire Airport, and
(III) any proceeds received by Lessor during such Fiscal Year from the sale of
the Airport property shown on Exhibit F, shall be deposited into the Airport
Development Fund, to be established and held by Lessor for the purposes
described in Article IIIB.2.(c)(ii) below.

        (x)  That it will subject all sales by it of the Airport property shown
on Exhibit F to noise easements in the form customarily used by Lessor as part
of its noise mitigation program.

        (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 any 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:

        (i)    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).

13

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

        (ii)  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.

        C.    FACILITIES USE FEES—FIS FACILITIES:    Lessor will charge each air
carrier operating at the Airport a facilities use fee per deplaned international
passenger of such air carrier for the use of the FIS Facilities at the Airport.
The Facilities Use Fees will be charged in accordance with the schedule attached
as Exhibit I.

        D.    CONTINUING RENTAL OBLIGATION:    

        1.    Should any scheduled air carrier, including Lessee, having an
agreement with Lessor substantially similar to the First Amended and Restated
Airport Agreement or to 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 such agreement, its continued obligation to pay to Lessor
charges thereafter due under such 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 paragraph 2 immediately below) payable at that time for
terminal building space at the Airport (whether leased under an Airport
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.

14

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

        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, 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.

        E.    YEAR-END ADJUSTMENT PAYMENTS AND CREDITS:    Commencing with
Fiscal Year 2009, as part of the preliminary annual settlement and Final Audit
for each Fiscal Year pursuant to Article IIIG.5 below, the County will calculate
for such Fiscal Year the Cost of the South Terminal, the Cost of the North
Terminal, the Cost of the South Terminal Airline Premises, the Cost of the South
Terminal County-Controlled Airline Space, the Cost of the North Terminal Airline
Premises and the Cost of the North Terminal County-Controlled Airline Space. The
Cost of the South Terminal County-Controlled Airline Space for any Fiscal Year
shall be an amount equal to the Cost of the South Terminal for such Fiscal Year
minus the Cost of the South Terminal Airline Premises for such Fiscal Year, as
such amounts are calculated pursuant to Article IIIA.2.(b)(iv) above. The Cost
of the North Terminal County-Controlled Airline Space for any Fiscal Year shall
be an amount equal to the Cost of the North Terminal for such Fiscal Year minus
the Cost of the North Terminal Airline Premises for such Fiscal Year, as such
amounts are calculated pursuant to Article IIIA.2(b)(v) above. The Signatory
Airlines shall make Year-End Adjustment payments, and shall receive Year-End
Adjustment credits as follows:

        1.    If (a) for any Fiscal Year the total Terminal Charges paid by
Signatory Airlines for the South Terminal Airline Premises are greater than or
equal to the Cost of the South Terminal Airline Premises for such Fiscal Year,
and (b) for such Fiscal Year the South Terminal County-Controlled Airline Space
Revenues are greater than the Cost of the South Terminal County-Controlled
Airline Space ("Surplus South Terminal County-Controlled Airline Space
Revenues"), then as part of the preliminary annual settlement and the Final
Audit for such Fiscal Year, each Signatory Airline leasing Preferential South
Terminal Space or using Shared Use South Terminal Space will receive a credit
equal to its pro rata share (which for each Signatory Airline shall be a
fraction, the numerator of which is the total number of square feet of its
Preferential South Terminal Space and the denominator of which is the total
number of square feet of Preferential South Terminal Space of all Signatory
Airlines) of the Surplus South County-Controlled Airline Space Revenues.

        2.    If (a) for any Fiscal Year the Cost of the South Terminal Airline
Premises is greater than the total Terminal Charges paid by Signatory Airlines
for the South Terminal Airline Premises ("Excess Costs of the South Terminal
Airline Premises"), and (b) there are Surplus South Terminal County-Controlled
Airline Space Revenues for such Fiscal Year, then as part of the preliminary
annual settlement and the Final Audit for such Fiscal Year, each Signatory
Airline leasing Preferential South Terminal Space or using Shared Used South
Terminal Space will (i) receive a credit equal to its prorata share of the
Surplus South Terminal County-Controlled Airline Space Revenues, and (ii) be
required to pay its prorata share of the Excess Costs of the South Terminal
Airline Premises.

        3.    If (a) for any Fiscal Year there are Excess Costs of the South
Terminal Airline Premises, and (b) for such Fiscal Year the South Terminal
County-Controlled Airline Space Revenues are less than or equal to the Cost of
the South Terminal County-Controlled Airline Space, then as part

15

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

of the preliminary annual settlement and the Final Audit for such Fiscal Year,
each Signatory Airline leasing Preferential South Terminal Space or using Shared
Use South Terminal Space will be required to pay its prorata share of the
difference between (i) the Cost of the South Terminal for such Fiscal Year minus
(ii) the sum of (A) the total Terminal Charges paid during such Fiscal Year by
Signatory Airlines for the South Terminal Airline Premises and (B) the South
Terminal County-Controlled Airline Space Revenues for such Fiscal Year (such
difference is hereinafter referred to as "Excess South Terminal Costs").

        4.    If (a) for any Fiscal Year the total Terminal Charges paid by
Signatory Airlines for the South Terminal Airline Premises are greater than or
equal to the Cost of the South Terminal Airline Premises for such Fiscal Year,
and (b) for such Fiscal Year the South Terminal County-Controlled Airline Space
Revenues are less than the Cost of the South Terminal County-Controlled Airline
Space, then as part of the preliminary annual settlement and the Final Audit for
such Fiscal Year, each Signatory Airline leasing Preferential South Terminal
Space or using Shared Use South Terminal Space will be required to pay its
prorata share of the Excess South Terminal Costs, if any, for such Fiscal Year.

        5.    If (a) for any Fiscal Year the total Terminal Charges paid by
Signatory Airlines for the North Terminal Airline Premises are greater than or
equal to the Cost of the North Terminal Airline Premises for such Fiscal Year,
and (b) for such Fiscal Year the North Terminal County-Controlled Airline Space
Revenues are greater than the Cost of the North Terminal County-Controlled
Airline Space ("Surplus North Terminal County-Controlled Airline Space
Revenues"), then as part of the preliminary annual settlement and the Final
Audit for such Fiscal Year, each Signatory Airline leasing Preferential North
Terminal Space or using Shared Used North Terminal Space will receive a credit
equal to its prorata share (which for each Signatory Airline shall be a
fraction, the numerator of which is the total number of square feet of its
Preferential North Terminal Space and the denominator of which is the total
number of square feet of Preferential North Terminal Space of all Signatory
Airlines) of the Surplus North County-Controlled Airline Space Revenues.

        6.    If (a) for any Fiscal Year the Cost of the North Terminal Airline
Premises is greater than the total Terminal Charges paid by Signatory Airlines
for the North Terminal Airline Premises ("Excess Costs of the North Terminal
Airline Premises"), and (b) there are Surplus North Terminal County-Controlled
Airline Space Revenues for such Fiscal Year, then as part of the preliminary
annual settlement and the Final Audit for such Fiscal Year, each Signatory
Airline leasing Preferential North Terminal Space or using Shared Use North
Terminal Space will (i) receive a credit equal to its prorata share of the
Surplus North Terminal County-Controlled Airline Space Revenues, and (ii) be
required to pay its prorata share of the Excess Costs of the North Terminal
Airline Premises.

        7.    If (a) for any Fiscal Year there are Excess Costs of the North
Terminal Airline Premises, and (b) for such Fiscal Year the North Terminal
County-Controlled Airline Space Revenues are less than or equal to the Cost of
the North Terminal County-Controlled Airline Space, then as part of the
preliminary annual settlement and the Final Audit for such Fiscal Year, each
Signatory Airline leasing Preferential North Terminal Space or using Shared Use
North Terminal Space will be required to pay its prorata share of the difference
between (i) the Cost of the North Terminal for such Fiscal Year minus (ii) the
sum of (A) the total Terminal Charges paid during such Fiscal Year by Signatory
Airlines for the North Terminal Airline Premises and (B) the North Terminal
County-Controlled Airline Space Revenues for such Fiscal Year (such difference
is hereinafter referred to as "Excess North Terminal Costs").

        8.    If (a) for any Fiscal Year the total Terminal Charges paid by
Signatory Airlines for the North Terminal Airline Premises are greater than or
equal to the Cost of the North Terminal

16

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

Airline Premises for such Fiscal Year, and (b) for such Fiscal Year the North
Terminal County-Controlled Airline Space Revenues are less than the Cost of the
North Terminal County-Controlled Airline Space, then as part of the preliminary
annual settlement and the Final Audit for such Fiscal Year, each Signatory
Airline leasing Preferential North Terminal Space or using Shared Use North
Terminal Space will be required to pay its prorata share of the Excess North
Terminal Costs, if any, for such Fiscal Year.

        F.    PASSENGER CREDIT:    Commencing with Fiscal Year 2009, for each
Fiscal Year each Signatory Airline will receive a credit (a "Passenger Credit")
against the total amount of its Terminal Charges and Activity Fees otherwise
payable under its Airport Agreement calculated by multiplying the Passenger
Credit Revenue Amount by a fraction, the numerator of which is such Signatory
Airline's total enplaned passengers at the Airport for such Fiscal Year and the
denominator of which is the total enplaned passengers at the Airport for such
Fiscal Year of all Signatory Airlines.

        G.    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
Lessee's domestic and international enplaned passengers, (iii) the number of
domestic and the number of international deplaned passengers of Lessee that are
estimated to use each of the Shared Use Domestic South Terminal Space, the
Shared Use International South Terminal Space, the Shared Use Swing South
Terminal Space, the Shared Use Domestic North Terminal Space, the Shared Use
International North Terminal Space and the Shared Use Swing North Terminal
Space, as the case may be, (iii) the total number of arriving and departing
domestic and international flights of Lessee, and (iv) the South Terminal 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 the actual number of Lessee's
deplaned passengers for the preceding calendar month that used each of the
Shared Use Domestic South Terminal Space, the Shared Use International South
Terminal Space, the Shared Use Swing South Terminal Space, the Shared Use
Domestic North Terminal Space, the Shared Use International North Terminal Space
and the Shared Use Swing North Terminal Space, as the case may be, (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 South O&M Expenses actually paid
by Lessee pursuant to Article VII.B. for the preceding calendar 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 and estimated calculation for the next ensuing Fiscal Year (the
"Projection") of the Terminal Rental Rate, Lessee's Terminal Charges, the
Activity Fee rate per thousand pounds of Approved Maximum Landing Weight,
Lessee's Activity Fees and the total Passenger Credit to be received by Lessee.
Such Projection will include Lessor's proposed Airport budget (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, Activity Fees and Passenger Credit for the next
ensuing Fiscal Year unless and until otherwise revised pursuant to paragraph 4
below.

17

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

        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
(i) 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, plus (ii) 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 IIIB.1., and
based on the Projection, as such projection may have been revised pursuant to
paragraph 4 below, minus (iii) 1/12 of Lessee's Passenger Credit for such Fiscal
Year, computed in accordance with Article IIIF., and based on the Projection, as
such projection may have been revised pursuant to paragraph 4 below.

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

        4.    ADJUSTMENT OF TERMINAL CHARGES 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 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 (taking into account
the Passenger Credit), at the then-existing rates would result in an overpayment
or underpayment of the aggregate amount required to be generated by Lessor
through 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 Terminal Charges,
Activity Fees and Year-End Adjustment payments estimated to be chargeable to
Lessee for the preceding Fiscal Year and the Passenger Credit and Year-End
Adjustment credits estimated to be credited 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 was 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

18

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

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 Terminal Charges, Activity Fees and Year-End Adjustment
payments chargeable, and the Passenger Credit and Year-End Adjustment credits to
be credited, 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.

        H.    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 that certain
Airport Agreement dated February 26, 1959, as amended, to which Lesser and
Lessee were at one time parties:

        1.    $463,984.20 for the United Airlines relocation project;

        2.    $12,015.00 for the Concourse G elevator project;

        3.    $254,158.68 for the extension to Concourse C; and

        4.    $1,206,095.64 for the new Concourse G and related projects.

Lessee will pay the above annual Bond Debt Service on that portion of the Bonds
issued by Lessor in 1993 and 1996 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 the aforesaid
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.

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 preferential use and may
construct or install at its own expense, any equipment, improvements and

19

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

facilities authorized under Article I hereof upon any Airport property not
leased to Lessee for its 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 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 preferential use or upon Airport property not leased to it for its
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 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 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 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.

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 preferential or
shared use, and shall provide reasonable illumination and drinking water in the

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 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 with respect to the South Terminal, pursuant
to the following agreements:

        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 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 IIIG.1.(b)(iv) above, Lessee shall render a
detailed statement for reimbursement of the 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. Lessee
also shall be entitled to reimbursement from Lessor for any costs incurred by
Lessee 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. Lessor shall be
entitled to audit all monthly statements of costs rendered by Lessee, and Lessee
will make available to Lessor all of the records supporting such statements. In
lieu of reimbursement payments by Lessor to Lessee of Lessee's aforesaid costs,
Lessee shall be entitled to net the reimbursement amounts against payments due
Lessor pursuant to Article III.G.3 above. All such costs shall be deemed to be
South Terminal O&M Expenses, and includible as such for all purposes under this
Agreement.

        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.

        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, member-only club facilities within such appropriate space leased
to it in the South Terminal for such purposes, which club facilities shall be
authorized to serve food and beverages; provided, however, food and beverages
served in such member-only club facilities will be obtained by Lessee from an
Airport food concessionaire to the extent that same are available for purchase
from an Airport food concessionaire.

ARTICLE XI

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.

ARTICLE XII

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.

23

(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

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

payable by Lessee to Lessor hereunder, or (2) any provision of this Agreement
authorizing Lessee in specified events to deduct from any such rentals, fees 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,

24

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

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

or from the Airport;

        (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

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

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

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

        Lessee's performance of all or any part of this Agreement for or during

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

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

25

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

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 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.

provided or from any other obligation under this Agreement.

EXHIBIT D

Protocol for Use of International Gates Midfield Terminal

        This Exhibit sets fourth utilization procedures for the
twelve-(12) international gates at the McNamara Terminal and shall take effect
upon commencement of operations at such gates. These procedures will apply to
any future international gates at the McNamara Terminal.

        The International gates, together with related hold rooms, passenger
loading bridges, ramp access and baggage facilities shall be made available for
arrivals or departures based on the following priorities:

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

2.Regularly scheduled Northwest domestic service;

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

4.Irregular or Diversion international arrivals of scheduled airline;

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

6.Northwest Airlines domestic irregular and diversion aircraft.

        In the event the FAA makes a determination in writing that the foregoing
priority of regularly scheduled Northwest domestic service over international
charter arrivals if and for so long as the Federal government prohibits FIS
operations at the Berry International Terminal would cause the international
gates at the Midfield Terminal to cease to be PFC-eligible or would be a
non-competitive procedure, Lessor and Lessee shall negotiate in good faith a
resolution permitting international charter arrivals to have access to FIS
operations on a basis sufficient to satisfy all applicable governmental
requirements, charter arrivals at the Midfield Terminal international gates on a
reasonable basis considering the scheduled operations of Lessee.

        The following criteria will be used to make the determination that an
airline is offering scheduled service:

•The International operation of the airline generally has passengers connecting
at the Airport on-line, inter-line, or via code share, and the operational need
for connecting facilities.

•The Airline operating the flight is a signatory under the use and lease
agreement of the Airport.

•The Airline holds all necessary government approvals to operate international
regularly scheduled service.

•The Airlines international service is scheduled on a year-round basis or is
offered seasonally on an annual basis.

•The Airline's schedules are published in the Official Airline Guide and
displayed in computer reservation systems, and the fares regularly published by
the Airline Tariff Publishing Company.

•The Airlines provide reservation services and create PNRs (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.

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

        The County will review with Northwest Airlines and other scheduled
international carriers, on an annual (or more frequent) basis, the procedures
for scheduling, gate occupancy times, ramp storage locations and penalties for
non-compliance.
