AIRLINE OPERATING AGREEMENT AND TERMINAL BUILDING LEASE

MINNEAPOLIS-ST. PAUL INTERNATIONAL AIRPORT

This Amended and Restated Third Amendment to Airline Operating Agreement and Terminal Building Lease (the “Amended and Restated Third Amendment”) is entered into as of the 28th day of December 2007, by and between the Metropolitan Airports Commission, a public corporation under the laws of the State of Minnesota (hereinafter sometimes referred to as “MAC” or “Commission”), and Northwest Airlines, Inc., a corporation organized and existing under the laws of Minnesota and authorized to do business in the State of Minnesota (hereinafter referred to as “AIRLINE”).

WHEREAS, MAC and AIRLINE entered into an Airline Operating Agreement and Terminal Building Lease effective January 1, 1999 and amended such agreement as shown on Exhibit 1 (collectively, “Lease”).

WHEREAS, MAC and AIRLINE entered into the Third Amendment to Airline Operating Agreement and Terminal Building Lease dated May 9, 2007 and it has become necessary to modify certain provisions contained in such Third Amendment to conform Third Amendment with the form of the 2007A Amendment to the Airline Operating Agreement and Terminal Building Lease entered into between MAC and the other Signatory Airlines as set forth herein.

WHEREAS, AIRLINE, NWA, Inc. (“NWA”), Northwest Aerospace Training Corporation (“NATCO)”; collectively with Airline and NWA, the “Northwest Entities”) and MAC are parties to a series of agreements and documents with respect to the Minneapolis-St. Paul Metropolitan Airports Commission General Obligation Revenue Refunding Bonds, Series 15 (all such agreements, guaranties, security documents and other documents shall be collectively referred to as the “GO 15 Documents”).

WHEREAS,  the Northwest Entities filed a petition under Chapter 11 of Title 11 of the United States Code on September 14, 2005, which case is pending in the United States Bankruptcy Court for the Southern District of New York in an administratively consolidated case entitled In re Northwest Airlines Corporation et al.,  Case No. 05-17930(ALG) (“2005 Bankruptcy Case”).

WHEREAS, as part of its reorganization in the 2005 Bankruptcy Case, AIRLINE and MAC negotiated a comprehensive resolution of all lease and debt issues between them as set forth in a Memorandum of Understanding executed by AIRLINE on February 12, 2007 and by MAC on February 19, 2007 (“MOU”).  As part of such comprehensive agreement documented in the MOU, AIRLINE requested that, and MAC agreed to, make significant changes to the existing Airline Operating Agreement and Terminal Building Leases between the MAC and each Signatory Airline, including AIRLINE’s Lease, that would provide substantial reductions in rates and charges payable by each Signatory Airline, including AIRLINE, and requiring that MAC share revenue generated from various sources at the Airport with such airlines.

WHEREAS, as part of such comprehensive agreement, MAC has agreed to amend the existing Airline Operating Agreement and Terminal Building Leases between the MAC and each Signatory Airline, including AIRLINE’s Lease on the terms and conditions set forth herein, provided that (i) each Signatory Airline shall be entitled to the reduction of rates and charges and the revenue sharing to be provided by the MAC hereunder only to the extent that such airline remains in compliance with all of its obligations to the MAC, and (ii) in the case of AIRLINE, (a) the Northwest Entities agree that their plan of reorganization will provide that the Northwest Entities will continue to fully perform all obligations under the GO 15 Documents with all such obligations remaining unimpaired, and (b) the GO 15 Documents shall be amended to, among other things, pledge the right of AIRLINE to receive revenue sharing proceeds to MAC as security for AIRLINE’S obligations under the GO 15 Documents.

WHEREAS, the Amendment evidenced hereby and the protections described above are an essential part of the comprehensive resolution and are fundamental to the Agreement contained in the MOU.

WHEREAS, in consideration for, among other things, the foregoing and at AIRLINE’S request, MAC is willing to allow the future anticipated revenue sharing proceeds to be used to determine the AIRLINE’S compliance with its minimum collateral requirements under the GO 15 Documents.

WHEREAS, AIRLINE hereby acknowledges and accepts that it is reasonable and non-discriminatory under the circumstances that pursuant to the Amendment to Lease dated March 29, 2002, MAC may cancel AIRLINE’s Short Term Gates for any Airline proposing to add additional air service and desiring to lease a gate directly from MAC, while the same Short Term Gate provision applicable to other Signatory Airlines provides MAC the ability to cancel the lease of a Short Term Gate only for if an Airline presently not leasing a gate directly from MAC or not currently providing air service to the airport is proposing to add additional air service and desires to lease a gate directly from MAC.

1.                                        In order to use the International Arrivals Facility, AIRLINE must maintain its status as International Regularly Scheduled Airline Service. AIRLINE shall provide MAC a detailed written certification for each numbered element on Exhibit H, upon MAC’s request. MAC retains the right to verify the status of AIRLINE and determine whether AIRLINE qualifies as International Regularly Scheduled Airline Service.

6.                                        Northwest shall be responsible for all maintenance, repair, and operation of MAC jet bridges provided by MAC as part of the IAF.  Northwest shall make the MAC jet bridges available for use by all users of the IAF without additional charge.

c.                                        To facilitate the providing of air services at the Airport by an Airline (“Requesting Airline”) when no Airline serving the Airport is willing to accommodate the Requesting Airline’s operational needs or requirements for facilities at reasonable costs or on other reasonable terms.

d.                                       To accommodate the irregular activity of another Airline (“Irregular Need”).

e.                                        To accommodate the Irregular Need of AIRLINE.  To the extent possible, AIRLINE shall accommodate its Irregular Need on its Preferential Use gate(s).  When such activity may not be accommodated on AIRLINE’S Preferential Use gate(s), AIRLINE shall seek accommodation from other Airlines on its own through coordination among such Airlines’ supervisors and managers.  In the event accommodation cannot be found on another Airline’s premises, AIRLINE may seek assistance from MAC.  MAC’s options shall include assigning use of non-leased gate premises or referring AIRLINE to MAC’s agent responsible for managing MAC’s remote parking locations.  For an Irregular Need, MAC shall not be responsible for unilaterally accommodating an Airline on another Airline’s leased premises.

4.                                        When necessary, MAC shall make a determination as to whether any Airline has underutilized facilities or capacity available.  In making such determination MAC shall not act unreasonably.  Such determinations by MAC shall take into consideration the following:

a.                                        The then existing utilization of AIRLINE’s Premises (including any requirements for spare gates and accommodation of AIRLINE’s Affiliates) and any bona fide plan of AIRLINE or any other Airline for the increased utilization of the AIRLINE’s Premises to be implemented within twelve (12) months thereafter (any non-public information provided by AIRLINE regarding planned or proposed routes, schedules or operations shall be treated as confidential by MAC to the maximum extent permitted by law).

b.                                       The need for compatibility among the current schedules, including RON requirements, flight times, operations, operating procedures and equipment of AIRLINE (and its Affiliate(s)) or any other Airline and those of the Requesting Airline or the Airline seeking accommodation of Irregular Need, as well as the need for labor harmony, facilities, resources, and other relevant factors.

c.                                        During irregular operations, AIRLINE’S scheduled operations will have priority over any accommodated Airline on its Premises.

d.                                       Any flights scheduled on AIRLINE’s Preferential use gate(s) must vacate the gate at least 45 minutes before the next use by AIRLINE.

e.                                        The maximum gate occupancy by narrow body aircraft for a Requesting Airline or an Airline seeking accommodation of Irregular Need shall be 45 minutes for an arrival, 45 minutes for a departure, or 1 hour and 30 minutes for a combined turn.

f.                                          The maximum scheduled gate occupancy by wide body aircraft for a Requesting Airline or an Airline seeking accommodation of Irregular Need shall be 1 hour for an arrival, 1 hour for a departure, or 2 hours for a combined turn.

g.                                       Any aircraft occupying a gate longer than the above timeframes may be required to vacate the gate to accommodate other operations.  Should this occur, upon AIRLINE’s request MAC will notify the Airline being accommodated as soon as MAC becomes aware of the requirement, but in any event no later than 15 minutes before the time that actual vacating is required.  Failure to vacate shall result in the imposition of additional overtime fees by AIRLINE to the accommodated Airline. If an Airline being accommodated does not vacate a gate as required, and AIRLINE requires the use of such gate, upon AIRLINE’s request MAC shall instruct Airline to remove its aircraft to another location leased by the Airline or to a remote location as designated by MAC’s agent.  If failure of the accommodated Airline to remove its aircraft results in AIRLINE requiring remote parking from MAC, MAC shall invoice the

8

accommodated Airline for any remote parking fees that would be charged to AIRLINE.

h.                                       Before MAC accommodates a Requesting Airline within AIRLINE’s Premises, MAC must give AIRLINE ten (10) days prior written notice of its intent. AIRLINE must accept accommodation or notify MAC within ten (10) business days after AIRLINE’s receipt of such notice that it wishes to meet with MAC to show cause why the accommodation should not be made.

5.                                        The accommodated Airline shall be responsible for the payment of all applicable fees and charges for such use, including but not limited to appropriate FIS charges and overtime fees.

a.                                        AIRLINE shall be authorized to (i) charge such accommodated Airline a reasonable accommodation fee and (ii) require from the accommodated Airline an indemnity and defense undertaking, so long as such undertaking is not more favorable to AIRLINE than that which AIRLINE provide to MAC.

b.                                       Each accommodated Airline shall be responsible for (i) ensuring that its agents, employees, and contractors are properly qualified prior to operating any and all equipment and (ii) are responsible for securing jetway doors upon completion of use.

c.                                        AIRLINE shall not be required to indemnify and save harmless MAC, its employees or agents with regard to any claim for damages or personal injury arising out of any accommodated Airline’s use of AIRLINE’s premises, unless caused by the negligence of AIRLINE;

d.                                       AIRLINE shall not be liable to any accommodated Airline or any of its agents, employees, servants or invitees, for any damage to persons or property due to the condition or design or any defect in the Premises which may exist or subsequently occur, and such accommodated Airline, with respect to it and its agents, employees, servants and invitees shall be deemed to have expressly assumed all risk and damage to persons and property, either proximate or remote, by reason of the present or future condition or use of AIRLINE’S Premises.  Further, such accommodated Airline shall be deemed to have agreed to release, indemnify, hold harmless and defend AIRLINE, the MAC, and their respective officers, directors, employees, agents, successors and assigns, from and against any and all suits, claims, actions, damages, liabilities and expenses (including, without limitation, attorneys’ fees, costs and related expenses) for bodily or personal injury or death to any persons and for any loss of, damage to, or destruction of any property, including loss of use, incidental and consequential damage thereof, arising out of or in any manner connected with the use of AIRLINE’S Premises by such accommodate Airline or any of its agents, representatives, employees, contractors or invitees, whether or not occurring or arising out of the negligence, whether sole, joint, concurrent, comparative, active, passive, imputed or any other type, of AIRLINE, MAC or their respective officers, directors, employees or agents; provided, however, the

9

foregoing indemnification shall not apply to any claim or liability resulting from the gross negligence or willful misconduct of AIRLINE, its officers, directors, employees or agents.

e.                                        MAC shall be responsible for ensuring that such accommodated Airline has in full force and effect MAC’s required insurance coverages.

f.                                          Without limiting any other provision of this Amended and Restated Third Amendment, AIRLINE’s duty to accommodate another airline shall be conditioned on and subject to the satisfaction of all requirements of this Section 6.

7.                                        In the event of a labor stoppage or other event which results in the cessation or substantial reduction in AIRLINE’s flights operations at the Airport, AIRLINE will immediately take all reasonable efforts, including but not limited to, moving of aircraft or equipment, providing access to AIRLINE’s holdrooms and jet bridges or anything else in AIRLINE’s control, in order to accommodate the operations of other Airlines providing air service to the Airport; provided that: (a) AIRLINE at all times will have access to its premises and equipment for operational reasons and (b) AIRLINE shall not be required to take any action which would interfere with its ability to re-institute service upon cessation of labor stoppage or other event. Subject to a mutually acceptable agreement between MAC and AIRLINE covering such use, AIRLINE shall have the right to charge reasonable fees and to require reasonable advance payment for such use of AIRLINE’s gates, holdroom areas, and loading bridges (and any such fees not in excess of 115% of the rates and charges payable by AIRLINE hereunder for such premises shall be deemed reasonable).

8.                                        The foregoing shall not be deemed to abrogate, change, or affect any restrictions, limitations or prohibitions on assignment or use of the AIRLINE’s Premises by others under this Agreement and shall not in any manner affect, waive or change any of the provisions thereof.

2.                                        MAC may, in its discretion, cancel the lease of a Short Term Gate leased by AIRLINE if an Airline is proposing to add additional air service and desires to lease a gate directly from MAC. The following procedures shall be followed before a Short Term Gate lease may be cancelled:

a.                                        If an Airline is proposing to add additional air service and desires to lease a gate directly from MAC, MAC may in its discretion issue a Notice of Cancellation.  The Notice of Cancellation may become effective after ninety (90) days.

6.                                        If AIRLINE is leasing three (3) or fewer holdrooms from MAC, MAC agrees to not cancel the lease of more than one Short Term Gate AIRLINE may be leasing in accordance with the procedures identified in Article IV.H.2. as long as AIRLINE has adhered to the payment and utilization requirements identified within Article IV.H.5. for all leased gates for the previous twelve (12) consecutive months.

3.                                        Within fifteen (15) days after receipt of the preliminary calculation of rents, fees, and charges, if requested by the Signatory Airlines, a meeting shall be scheduled between MAC and the Signatory Airlines to review and discuss the proposed rents, fees, and charges.

4.                                        MAC shall then complete a calculation of rents, fees, and charges at such time as the budget is approved, taking into consideration the comments or suggestions of AIRLINE and the other Signatory Airlines.

5.                                        If, for any reason, MAC’s annual budget has not been adopted by the first day of any Fiscal Year, the rents, fees, and charges for the Fiscal Year will initially be established based on the preliminary calculation of rents, fees, and charges until such time as the annual budget has been adopted by MAC. At such time as the annual budget has been adopted by MAC, the rents, fees, and charges will be recalculated, if necessary, to reflect the adopted annual budget and made retroactive to the first day of the Fiscal Year.

6.                                        If, during the course of the year, MAC believes significant variances exist in budgeted or estimated amounts that were used to calculate rents, fees, and charges for the then current Fiscal Year, MAC may after notice to Airlines adjust the rents, fees, and charges for future reports to reflect current estimated amounts.
