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

     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

                                      -7-
<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

          as evidenced by written notice thereof from Lessor to Lessee, for each
          Fiscal Year or portion thereof (on a pro rated basis), through Fiscal

          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

          Fiscal Year.

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

          such Fiscal Year and the Midfield Domestic Bond Debt Service Rate for
          such Fiscal Year.  The Midfield Domestic O&M Rate for any Fiscal Year
          shall be determined by dividing (i) Midfield O&M Expenses for such
          Fiscal Year allocated to the Domestic Area of the Midfield Terminal by

          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

          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.

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 represented by an
"Activity Fee" calculated for each Fiscal Year, and which shall be an amount
equal to the product of the number of thousand pounds of Approved Maximum
Landing Weight of aircraft landed at the Airport in such Fiscal

                                      -29-
<Page>

Year, multiplied by the Activity Fee rate for such Fiscal Year.  The Activity
Fee rate for any Fiscal Year shall be the quotient arrived at by dividing:

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

          (b)  the aggregate amount of Approved Maximum Landing Weight of
          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)  O&M Expenses 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 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, less (c) any PFC
          revenues received by Lessor during such Fiscal Year and allocated by
          Lessor to pay principal and interest on outstanding Bonds in such
          Fiscal Year; 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

                                      -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

          (6)  all other Airport revenues (including, but not limited to, all
          rental charges for Existing Terminal Facilities, Terminal Charges and
          all concession and parking revenue) received [or receivable if the
          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.

     2.   LESSOR COVENANTS; CAPITAL EXPENDITURES:

     (a)  Lessor covenants:

               (i)   That it will provide efficient management and operation of
          the Airport on the basis of sound business principles and that it will
          not incur expense for Airport operation, maintenance and
          administration in excess of the amounts reasonably and necessarily
          required therefor.

               (ii)  That it shall operate the Airport in a manner so as to
          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-
<Page>

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.

     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 the0 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

     4.   $1,958,194.00 for the new Concourse G and related projects.

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.

                                    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 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.

     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.

     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.

     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.

                                      -55-

     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
assets pursuant to proceedings brought under the provisions of any Federal
reorganization act if the judgment of such court shall remain unvacated or
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

     (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

                                      -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,

     (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

                                      -59-

subsequent default of any of the terms, covenants and conditions herein

                            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
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.

                                      -61-
<Page>

     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.

negligence or by the joint negligence of Lessor and any person other than

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.

adequate financial responsibility, insuring Lessee against all liabilities to
the public for loss resulting from injury to persons or damage to property

                        AND FACILITIES ERECTED BY LESSEE

     It is agreed that title to any equipment, improvements, and facilities, and
any additions thereto, irrespective of whether the same would otherwise become a
fixture under Michigan law (including without limitation all buildings, hangars,

conditioning equipment), constructed or installed by Lessee upon the premises
leased hereunder to Lessee for its exclusive or preferential use or upon other

improvements and facilities financed by Lessor, whether with the proceeds of
Bonds, PFCs, Federal funds or otherwise), shall remain the property of Lessee,
unless it has at any time during the term of this Agreement by written notice
and election, vested title to all or any part thereof in Lessor. Lessee shall
have the right at any time during the term of this agreement, or any renewal or
extension hereof, to remove any or all of such equipment, improvements and
facilities, provided Lessee is not at any such time in default in its payments
to Lessor hereunder and subject further to Lessee's obligation to repair all
damage, if any, reasonable wear and tear excepted, resulting from such removal.
If at any time during this Agreement, Lessee has exercised its right to vest
title to such equipment, improvements and facilities in Lessor, it shall no
longer have the right to remove such property. Lessee agrees to remove said
equipment, improvements and facilities at the expiration or other termination of
this Agreement irrespective of whether it has exercised its right of election to
vest title to the same in Lessor, if so requested by Lessor, and, upon failure
so to do, Lessor shall have the right to remove the same and charge to Lessee
the actual cost of such removal and restoration of the site to its original
condition, ordinary wear and tear excepted. Any such equipment, improvements or
facilities not removed by Lessee prior to the expiration or other termination of
this Agreement shall thereupon become the property of Lessor.

writing of Lessor, which consent will not be unreasonably withheld; provided,
that the foregoing shall not prevent the assignment of this Agreement to any
corporation with which Lessee may merge or consolidate, or which may succeed to
the business of Lessee. No such subletting, however, shall release Lessee from
its obligations to pay any and all of the rentals, charges, and fees provided or
from any other obligation under this Agreement.

     B.   Except as provided in Article IIIB.2.(b), Lessor shall not at any time
assign this Agreement or any part hereof, or pledge, sell, convey, mortgage,

     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
<Table>

                      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
</Table>

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.

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.

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.

3) Other Airport                                                          Expenses Flow to

   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.
