All such signs, posters, displays, and other similar materials must be approved in writing by the Authority prior to use at the Airport. The Authority reserves the right to place advertising displays in all areas of the Airport that are visible to the public excluding the Exclusive Use Premises and holdroom areas leased to the Airline. The Authority agrees not to allow the placement of advertising of competing route services in the Airline's Premises or common use areas. 4.01.7 To install, maintain and operate at no cost to the Authority, alone or in conjunction with any other Signatory Airline, radio communication, computer, meteorological and aerial navigation equipment and facilities on the Airline's Premises; provided, however, that such installations shall be subject to the prior written approval of the Authority. 4.01.8 To install, maintain and operate customer relations, security and holdroom facilities and equipment, administrative offices, operations offices, and related facilities, and to install personal property, including furniture, furnishings, supplies, machinery and equipment, in the Airline's Premises. 4.01.9 To construct modifications, finishes and improvements in the Airline's Premises subject to the provisions of Section 10.09. 4.01.10 To have ingress to and egress from the Airports and the Airline's Premises for the Airline's officers, employees, agents, contractors, and invitees, including furnishers of services and supplies. 4.01.11 To use, for the benefit of the Airline's employees who perform substantially all of their work at the Airports, vehicular parking areas which will be designated by the Authority 4.01.12 To install soft drink vending machines and snack vending machines in the Airline's non-public Premises for the sole use of the Airline's officers, employees and agents. Vending machines shall not be within the view of the general public and all machine locations are subject to the prior written approval of the Authority. 4.01.13 To furnish and operate a preferred customer or "VIP" club for the Airline's passengers in Premises designated for this purpose by the Authority. Further, such preferred customer or "VIP" club may be shared with one or more other Air Transportation Companies; provided, however, that the club is leased to the Airline only, and provided that the rights of all the Air Transportation Companies using the club terminate when such lease terminates. 4.01.14 To install telephones, telefax, and other telecommunications devices and conduit in the Airline's Premises that are not accessible to the public. The Authority retains the right to install all public telephones, telefax, and other telecommunications devices and conduit in all areas of the Airports accessible to the public, including the Premises leased to the Airline, and to collect the proceeds therefrom; provided, however, the Airlines may install telephones and telefax in the Airline's "VIP" club. If the Airline installs public telephones or telefax in its "VIP" club, it shall pay to the Authority a monthly payment of fifty percent (50%) of the gross revenues received by the Airline from any source from the installation and operation of such telephones or telefax. 4.01.15 To install, operate and maintain, using the Airline's own employees or those of a wholly-owned subsidiary of the Airline or the Airline's parent company, an establishment for the cooking and preparation of food and beverages for consumption only by passengers and crews on the Airline's aircraft and in the Airline's "VIP" club, if any; provided that the Authority determines, in its discretion, that space is available on the Airports for this purpose and that, if such space is not included and designated in the Airline's Premises, the Airline enters into a separate agreement for such cooking and food preparation space with the Authority. Such food and beverages shall not be intended for consumption by any persons except the Airline's passengers and crews while on the Airline's aircraft, patrons of Airline's "VIP" club, and such employees directly engaged in the cooking and preparation of such food and beverages; provided, however, upon entering a separate agreement with the Authority, and subject to fees and conditions as set forth therein, the Airline may provide these services to one or more other Air Transportation Companies operating from the Airport, including another Signatory Airline. 4.01.16 To purchase prepared food and beverages for consumption by passengers and crews on the Airline's aircraft and in the Airline's "VIP" club, if any; provided, however, if the Airline purchases catering, not including beverages and complimentary packages of snack food to be consumed on the Airline's aircraft, from an off-Airport caterer including, but not limited to, an Air Transportation Company, for delivery of prepared food and/or beverages to the Airline on the Airport, said caterer will be required to have a contract with the Authority and to pay a fee to the Authority at a rate equal to the rate paid by the Authority's inflight food catering concessionaires located on that Airport. The Airline shall not purchase any prepared food or beverage from a caterer for delivery on the Airports unless and until the caterer is authorized by the Authority to do business on the Airports. 4.01.17 To acquire, by purchase or otherwise, any Air Transportation Business-related services and/or supplies from any agent, contractor, or other Signatory Airline subject to the conditions of Paragraph 4.02.5. 4.02 Exclusions, Reservations, and Conditions. The rights granted to the Airline under this Agreement shall be strictly construed, and may be exercised by the Airline only to the extent such rights are necessary or incidental to the conduct by the Airline of its Air Transportation Business. Except with the prior written approval of the Authority, the Airline is prohibited from conducting any business on the Airport separate and apart from the conduct of its Air Transportation Business. 4.02.1 If the Airline receives notice from the Authority, or if the Airline reasonably should know (i) that it is materially interfering with the use, operation or maintenance of the Airport, including but not limited to, the safe and efficient use of the Airfield and the effectiveness or accessibility of the drainage, sewerage, water, communications, fire protection, utility, electrical, or other systems installed or located from time to time at the Airport; (ii) that it is causing or contributing to a dangerous or hazardous condition; or (iii) that it is in violation of law or applicable rules or regulations; the Airline shall immediately cease such interference, or, where immediate elimination of said interference is not possible, the Airline shall immediately take corrective action and cause others under its control to take corrective action to eliminate the interference. 4.02.2 As soon as possible, after obtaining any necessary approval from appropriate governmental agencies, the Airline shall remove any of its disabled aircraft from the Landing Area and Ramp Area upon the request of the Authority. The Airline shall place any such disabled aircraft only in such storage areas as may be designated by the Authority, and shall store such disabled aircraft only upon such terms and conditions as at that time may be established by the Authority, consistent with any directives of the FAA and the National Transportation Safety Board. (i) In the event the Airline shall fail to remove any of its disabled aircraft as expeditiously as possible, the Authority may, but shall not be obligated to, cause the removal of such disabled aircraft by any reasonable means; provided however, the Authority shall give the Airline prior notice of its intent to do so. (ii) If the Authority removes, or causes another to remove the Airline's disabled aircraft, the Airline shall pay to the Authority, upon receipt of an invoice, the costs incurred for such removal, including the cost of labor. The Airline shall also pay any damages incurred by, or imposed upon the Authority as a result of the disabled aircraft. 4.02.3 Except as may otherwise be authorized herein or in separate agreements between the Airline and the Authority, the Airline shall not provide to its passengers, other Air Transportation Companies, or other persons on the Airport food or beverages, products or services of a kind normally provided by Airport concessionaires nor shall the Airline maintain or operate on the Airport a cafeteria, restaurant, bar, or cocktail lounge, stand, or any other facility for the purpose of providing food and beverages to the public or to the Airline's employees and passengers or to any other Air Transportation Company. This prohibition shall not apply to the Airline's "VIP" club to the extent the Airline provides, in such club, such food and beverage, products or services on a complimentary basis and such club is located and constructed in such a manner as to be separate and distinct from the space that is accessible by the public who are not members of the club and is physically separated by a wall or walls from the Airline's passenger holdroom or boarding area, where persons holding tickets to board the Airline's aircraft are congregating. Further, it shall not be construed to apply to the provision of food, beverages, products, or services aboard an aircraft. 4.02.4 The Airline shall not use, store, transport, or dispose of any fuels, oil, grease, lubricants, or other hazardous materials to, from, within, or upon the Airports in a manner which violates federal, state, local, or Authority laws and regulations. 4.02.5 If the Airline uses anyone other than its own employees, the employees of a parent or subsidiary company, or those of another Signatory Airline to perform the Air Transportation Business services and related activity authorized in this Article, the person or entity providing the service may be required to meet the Authority's reasonable qualifications for doing business on the Airports, and obtain an Authority permit, license, or contract if required to do so by the Authority. The Authority may also require the person or entity providing the services to pay reasonable fees or rents, except as otherwise provided in Section 8.10. The Airline shall provide the Authority with a copy of any contract or agreement between the Airline and the agent or contractor upon the Authority's request. 4.02.6 The Authority reserves the right to impose reasonable conditions on the use of the Fueling System at either Airport whenever a separate agreement on the use of the system is not in effect. In the event the Signatory Airlines fail to select a Fueling Agent by October 1, 1990, the Authority shall have the right to select its own agent to be responsible for the overall operation and maintenance of the Fueling System and to award a contract for a period not to exceed five (5) years to such agent; provided, however, that the Authority shall not select a Fueling Agent without first providing notice to the Signatory Airlines at the Airport (i) of the Authority's intent to select an agent, and (ii) of the anticipated date that the agent will assume responsibility for the Fueling System1 which date shall be at least ninety (90) days after the date of the said notice; and, provided, further, that if the Signatory Airlines thereafter select a different Fueling Agent, in accordance with Paragraph 4.01.5, the Authority shall, upon receipt of a written request from the Signatory Airlines, terminate its contract with the Fueling Agent selected by it at the earliest date upon which such contract may be terminated without penalty and shall thereupon enter into an agreement with such different Fueling Agent in accordance with Paragraph 4.01.5. 4.02.7 The Authority reserves the right to either temporarily or permanently restrict the use of any roadway, taxiway, or runway or other area at the Airport at any time, provided, that in the event of such restrictions, the Authority shall ensure the availability of reasonable ingress and egress, and shall not unreasonably restrict Airfield operations. 4.03 Operating Rights, Exclusions, and Conditions Applicable Only at National. In addition to the Airline's rights, privileges, and exclusions enumerated in Sections 4.01 and 4.02, the following rights, privileges, and exclusions are applicable to the Airline's operations at National: 4.03.1 The Airline may (i) use only those Aircraft Parking Positions at National shown on Exhibit N-B for enplaning and deplaning passengers, baggage, cargo and/or mail, and the servicing of aircraft; (ii) park an aircraft that is ready for immediate use as an extra section of a scheduled flight only at an area designated on Exhibit N-B; and (iii) park an aircraft overnight at a location at other than its Aircraft Parking Positions only with the express permission of the Authority and on reasonable terms and conditions, including payment of fees as set forth in Section 8.04. 4.03.2 Unless otherwise authorized by the Authority, the Airline must use the Fueling Agent to service its aircraft. 4.03.3 The Airline may not load or unload an all cargo aircraft on the passenger Ramp Areas adjacent to the Terminal facilities. 4.04 Operating Rights, Exclusions, and Conditions Applicable Only at Dulles. In addition to the rights, privileges, and exclusions enumerated in Sections 4.01 and 4.02, the following rights, privileges and exclusions are applicable to the Airline's operations at Dulles: 4.04.1 The Airline may use only those hard stand or Dulles Jet Apron positions assigned by the Authority for enplaning and deplaning passengers, baggage, cargo and mail, and for servicing of aircraft. 4.04.2 If the Airline leases space in the Airside Operations Building on the Dulles Jet Apron, the Authority, in its assignment of Dulles Jet Apron positions, will use its best efforts to assign the Airline those positions which are reasonably convenient to the Airline's Airside Operations Building space. The Airline may park aircraft overnight at a location other than the Airline's Aircraft Parking Positions, or assigned Dulles Jet Apron positions, if any, only with the prior permission of the Authority and on reasonable terms and conditions, including payment of fees as set forth in Section 8.04. 4.04.3 The Airline shall use only the Fueling Agent to fuel its aircraft, except that the Airline may use the Fixed Base Operators at Dulles to fuel the Airline's aircraft if the aircraft are on the FBO's own premises or on the Cargo Ramp, except as may be agreed to in a separate agreement between the Authority and the Fueling Agent. 4.04.4 The Airline may not load or unload cargo from all- cargo aircraft on the passenger Ramp Area adjacent to the Terminal or the Dulles Jet Apron positions. ARTICLE 5. TRANSITION PROVISIONS 5.01 Implementation of Capital Development Program. The Authority and the Airline agree that completion of the Capital Development Program shown in Exhibits N-I and D-I entails (i) the physical modification or removal of some Existing Airport Facilities and (ii) the modification in the function or use of other Existing Airport Facilities (whether or not these facilities are physically modified) and, in particular, the reduction in the number of Aircraft Parking Positions used for aircraft of other than Regional/Commuter Air Carriers in the Existing Airport Facilities at National Airport. Notwithstanding the preceding two sentences, after construction of the Capital Development Program at National Airport, the number of Aircraft Parking Positions for aircraft of Scheduled Air Carriers (other than Regional/Commuter Air-Carriers) at National where passengers enplane and deplane through a loading bridge shall be forty-four (44), the same as in the Existing Airport Facilities at National. 5.02 Temporary Airline Premises. 5.02.1 In order to implement the Capital Development Program in accordance with Section 5.01, the Airline agrees that the Premises leased to it pursuant to Section 6.01 will be deemed to be Temporary Airline Premises (TAP), and the Premises to be leased to it pursuant to Section 6.02 will be deemed to be the Airline's Permanent Premises. The implementation of the Capital Development Program may require the Airline to lease TAP on the Effective Date hereof. Further, the Airline may be required to relocate on a temporary or permanent basis, from TAP to Premises that are different from those that the Airline occupies on the Effective Date. Such relocation is anticipated by the Airline and the Authority but will occur only if it is reasonably necessary to accomplish the Capital Development Program. Further, such relocation may be from TAP into other TAP until the Airline relocates to Permanent Premises. However, at Dulles, the Airlines will not be required to relocate from the TAP initially leased under Section 6.01 into other TAP except as follows: (i) To implement the expansion and rehabilitation of the Dulles Main Terminal; (ii) To implement Dulles Stage II of the Capital Development Program; or Article 17. (iii) As part of a relocation required by Article 17. 5.02.2 Unless a different notice period and procedure is agreed to, the Airline's occupancy and use of TAP are subject to the notice and process provided in Paragraphs 5.02.3, 5.02.4, and 5.02.5 to vacate the TAP and to relocate to other TAP or to Airline's Permanent Premises. The Authority agrees to use its best efforts to (i) relocate the Airline to TAP suitable for the conduct of the Airline's Air Transportation Business, but not necessarily comparable in size, location, access, or other features of the Premises originally leased under Section 6.01, (ii) minimize operational disruptions to the Airline as a result of such relocations, and (iii) maintain a phasing schedule for implementation of the Capital Development Program, including the Substantial Completion Date of the Airline's Permanent Premises so as to not unreasonably interfere with the Airline's operation. 5.02.3 When, in the judgment of the Authority, implementation of the Capital Development Program requires the Airline to vacate TAP, the Authority shall give to the Airline not less than sixty (60) calendar days written notice to vacate any, or all, of the TAP, and the Authority shall then have the right to amend the Exhibits to this Agreement to reflect the deletion of the TAP from the Airline's Premises and in the Authority's sole discretion, to lease said TAP to another tenant or to close said TAP. The Airline agrees to vacate the TAP on the date specified in the said written notice, regardless of whether that date is the last day of the month; provided, however, that if the Airline notifies the Authority as promptly as is reasonably practicable upon receipt of such notice that it cannot reasonably prepare the TAP to which the Airline is being relocated within such notice period, and the reasons therefor, the Airline shall have additional time, not to exceed thirty (30) days, to vacate the TAP. 5.02.4 The Airline agrees that it will cooperate with the Authority in moving to TAP, in moving from TAP to other TAP, and in moving to Permanent Premises, and that it will move in such a manner so as not to interfere unreasonably with the Authority's planned Capital Development Program. The allocation of the Airline's costs associated with relocation to assist the Capital Development Program shall be in accordance with the Authority policy attached hereto as Exhibit A-P. 5.02.5 The Airline, while occupying TAP, shall be subject to all of the other conditions and terms of this Agreement. 5.03 Transition to Permanent Premises. 5.03.1 The Authority shall give written notice to the Airline of the estimated Substantial Completion Date of the Airline's Permanent Premises, at least one hundred and twenty (120) days prior to said date. The Airline will be permitted to install its own equipment and furnishings in the Airline's Permanent Premises beginning sixty (60) days prior to such estimated Substantial Completion Date. 5.03.2 The Airline shall move into and occupy its Permanent Premises on or before the actual Substantial Completion Date of such Permanent Premises whereupon such Permanent Premises shall not be considered TAP subject to Section 5.02; provided, however, that if the Airline notifies the Authority as promptly as is reasonably practicable upon receipt of the notice specified in Paragraph 5.03.1 that it cannot reasonably prepare its Permanent Premises by the estimated Substantial Completion Date, and the reasons therefor, the Airline shall have additional time, not to exceed thirty (30) days, to move into and occupy its Permanent Premises. Unless a different payment is required by Section 8.14, the Airline shall be subject to, and shall pay, the rentals, fees, and charges for its Permanent Premises beginning on the actual Substantial Completion Date thereof regardless of whether the Airline occupies its Permanent Premises prior to, on, or after such actual Substantial Completion Date. 5.03.3 If the Airline's Permanent Premises are not completed by the estimated Substantial Completion Date that was contained in the written notice given by the Authority pursuant to Paragraph 5.03.1, the Authority shall not be liable to the Airline for failure to deliver possession or to complete said Permanent Premises by said date. The Authority will notify the Airline of any change in such estimated Substantial Completion Date. ARTICLE 6. LEASE 6.01 Lease of Temporary Airline Premises and Equipment. The Authority, as lessor, hereby leases to the Airline, and the Airline, as lessee, hereby leases from the Authority, commencing on the date hereof and subject to all of the terms and conditions herein, particularly the transition provisions of Article 5, the following Temporary Airline Premises and Equipment: (i) The Exclusive Use Premises specifically described and identified as TAP in Exhibits N-B and D-B; (ii) The Joint Use Premises specifically described and identified as TAP in Exhibits N-B and D-B; (iii) The Preferential Use Premises specifically described and identified as TAP in Exhibits N-B and D-B; and (iv) The Equipment specifically described and identified as TAP in Exhibits N-H and D-H. 6.02 Lease of Permanent Premises and Equipment. Commencing on the Substantial Completion Date of the Airline's Permanent Premises, the Authority, as lessor, shall, without any further action, lease to the Airline, and the Airline, as lessee, shall, without any further action, lease from the Authority, subject to all of the terms and conditions herein, the following Permanent Premises and Equipment: (i) The Exclusive Use Premises described and identified in Exhibits N-B and D-B; (ii) The Joint Use Premises described and identified in Exhibits N-B and D-B; (iii) The Preferential Use Premises described and identified in Exhibits N-B and D-B; and (iv) The Equipment described and identified in Exhibits N-H and D-H. 6.03 Changes. All of the Premises and Equipment described in Sections 6.01 and 6.02 are subject to modification in accordance with Article 5, this Article 6, Article 16, and Article 17 of this Agreement. 6.04 Allocation of Premises at Dulles. At Dulles, prior to the completion of the design of the westerly expansion of the Main Terminal, and subsequently, prior to the completion of the design of the easterly expansion of the Main Terminal, the Authority will determine the location of each Airline's Premises in the expanded Main Terminal. The following will be the primary, but not exclusive, considerations in establishing the priority order of allocation: (i) The amount of space committed to by each Airline in an executed use and lease agreement; (ii) The individual Airline's preference with respect to location of its leasable Premises, and the desirability of, and operational requirements for, contiguous space for related functions; and (iii) The efficient phasing and implementation of the Main Terminal expansion, whereby relocations are minimized and flexibility for construction phasing is maximized. 6.05 Modification of Premises. In the event that the Authority and the Airline, by mutual agreement, add additional space or spaces to, or delete space or spaces from, the various Premises of the Airline, Exhibits N-B or D-B, as applicable, shall be revised accordingly to reflect such addition or deletion and the revised exhibits shall be incorporated into the Agreement. Space added to the Airline's Premises shall be subject to all of the terms, conditions, requirements, and limitations of this Agreement and the Airline shall pay to the Authority all rentals, fees, and charges applicable to such additional space in accordance with the provisions of this Agreement. 6.06 Addition of Equipment. 6.06.1 Subject to Paragraph 6.06.3, the Authority reserves the right to acquire and install Equipment in, upon, and adjacent to, the Airline's Premises but only in one or more of the following events: (i) The acquisition and installation of the Equipment is identified as part of the Capital Development Program; (ii) The acquisition and installation of Equipment is identified as part of any Additional Project; (iii) In any Premises, whenever there is a change in tenants; or (iv) Such acquisition and installation are agreed to between the Airline and the Authority. 6.06.2 The Airline agrees to facilitate the installation of the Equipment, including, upon reasonable notice from the Authority, the decommissioning and removal, at the Airline's expense, of the Airline's equipment, if any, that is to be replaced by Equipment pursuant to Paragraph 6.06.1. 6.06.3 Prior to the acquisition and installation of Equipment pursuant to Paragraph 6.06.1, the Authority shall consult with the Airlines with respect to the technical standards and requirements applicable to such Equipment. So long as such Equipment meets such standards and requirements, the Airline may select the vendor or supplier of Equipment for the Airline's Premises. At the request of the Airline, and provided that it would not adversely affect the tax-exempt status of the Bonds, the Authority may allow the Airline to initially purchase the Equipment and be subsequently reimbursed by the Authority. 6.07 Adjustment of Dimensions. After the Substantial Completion Date of each Airline's Permanent Premises, the actual square footage of the Airline's Premises shall be determined by the Authority from actual measurements, and incorporated into revised Exhibits N-B and N-C, and D-B and D-C. If measurements are to be taken, the Airline shall be notified in advance and shall be entitled to have a representative present when such measurements are taken. Premises consisting of enclosed space shall be measured for interior space from the center line of interior walls to the inside face of exterior walls. ARTICLE 7. OPERATION AND MAINTENANCE 7.01 Authority Responsibilities. 7.01.1 The Authority shall, with reasonable diligence and prudence, operate and maintain the Airports with adequate, efficient, qualified personnel, and keep the Airports in good condition and repair, including the Terminals, Ramp Area, Existing and New Midfield Concourses, Airside Operations Buildings, and any Passenger Conveyances between Existing and New Midfield Concourses or between aircraft and Terminals and the visual public display of arrival and departure flight information for the Dulles Main Terminal. 7.01.2 The Authority shall, with reasonable diligence and prudence, act to maintain the Landing Area for the safe and proper use thereof by the Airline, including the clearing and removal of snow from the runways and taxiways as quickly as reasonably practicable. 7.01.3 The Authority will operate and maintain the Airports in a manner at least equal to the standards established by the FAA to maintain the Airport Operating Certificates and any other governmental agency having jurisdiction thereof, except for conditions beyond the control of the Authority. 7.01.4 The Authority shall not be liable to the Airline for temporary failure to furnish all or any services to be provided by the Authority hereunder, whether due to mechanical breakdown or for any other causes beyond the reasonable control of the Authority. 7.01.5 The Authority's operation and maintenance responsibilities are set forth in Exhibits D-D and N-D, except that the Airline and the Authority may agree to a different allocation of maintenance responsibility in Exhibits N-B and D-B (leasehold exhibits) in which event any conflict between Exhibits D-D and ND and D-B and N-B shall be resolved in accordance with Exhibits D-B and N-B. Further, and except as may be provided in Exhibits D-B and N- B, the Authority shall not be obligated to perform the operation and maintenance responsibilities designated by Section 7.02 and Exhibits N-D and D-D as being the responsibility of the Airline, or for which the Airline, another Signatory Airline, or any other person has assumed such responsibility by separate written agreement with the Authority, including a Surviving Agreement. 7.01.6 The Authority shall provide, operate, and maintain the Passenger Conveyance system at Dulles, including a sufficient number of trained personnel. The Authority shall provide adequate Passenger Conveyances for the transportation of passengers between the Main Terminal and the Airline's aircraft that are parked on remote hard stand or on the Dulles Jet Apron at a parking position that is not serviced by a passenger holdroom and a loading bridge. The Airline shall determine who boards Passenger Conveyances traveling between the Dulles Main Terminal and its aircraft directly. On Passenger Conveyances serving aircraft directly, passengers enplaning or deplaning for more than one aircraft operation shall not be combined in a single one-way trip. Except in an emergency, the Authority shall not be obligated to provide transportation directly between the Terminal and the Airline's aircraft which is, or in the reasonable judgment of the Authority can be, parked at an Aircraft Parking Position at the Existing Midfield Concourse or New Midfield Concourse(s) and served by a passenger holdroom and a loading bridge. If the Passenger Conveyance has departed directly for the Airline's aircraft before all of the Airline's passengers have boarded it, the Airline may transport its passengers to or from its aircraft by another means subject to the Authority's approval. 7.01.7 The Authority and the Airline recognize that regular, shuttle-type mobile lounge service of high quality is important for the proper transportation of passengers to and from the Existing Midfield Concourse. The Authority agrees: (i) To use its reasonable best efforts to provide mobile lounge service from the Dulles Main Terminal to the Existing Midfield Concourse beginning one hour before any Airline's first departure from the Existing Midfield Concourse and will continue to operate on a regular basis until a half hour after the' last scheduled flight arrives, even if that flight is later than its scheduled arrival. (ii) To use its reasonable best efforts so that (a) after a mobile lounge departs from a terminus another takes its place as soon as practicable, and (b) regardless of the number of passengers carried, mobile lounges depart the terminus after waiting no more than five minutes for boarding passengers; provided that a lounge may remain at one or each terminus for a longer period if no passengers of a Signatory Airline are waiting service for transportation. (iii) An adequate number of gates at the Dulles Main Terminal will be designated as the gates from which the mobile lounges to the Existing Midfield Concourses will operate.

RENTALS, FEES, AND CHARGES 8.01 General. 8.01.1 The Airline shall pay to the Authority rentals for use of Premises at the Airports, and fees and charges for the other rights, licenses, and privileges granted hereunder during the Period of this Agreement. Such rentals, fees, and charges shall be calculated based on allocations of Total Requirements, reduced by Transfers, to the Cost Centers and Sub-Centers within the Airline Supported Areas and as specifically provided for herein and in Exhibits N-F and D-F and the accompanying Schedules. 8.01.2 In each Fiscal Year at each Airport, the total of rentals, fees, and charges payable by the Signatory Airlines hereunder (and, with respect to the Airfield Cost Center, by the Signatory Cargo Carriers), plus Transfers allocable to the Airline Supported Areas at such Airport for such Fiscal Year, shall in any event be at least equal to the sum of (i) O&M Expenses, (ii) amounts required to maintain the O&M Reserve, (iii) Debt Service, (iv) other Capital Charges, (v) Federal Lease payment, (vi) at Dulles, Dulles Rate Credit Amortization Requirement, (vii) required deposits, if any, to the Debt Service Reserve Fund, and (viii) required deposits, if any, to the Emergency R&R Fund allocable to the Airline Supported Areas at such Airport for such Fiscal Year; and, in each Fiscal Year, at each Airport, the total of rentals, fees, and charges payable hereunder by the Signatory Airlines (and, with respect to the Airfield Cost Center, by the Signatory Cargo Carriers), shall in any event be at least equal to the amount required such that total Revenues of that Airport, plus Transfers for such Fiscal Year, less Operating and Maintenance Expenses at that Airport, for such Fiscal Year, shall be at least equal to one hundred twenty-five percent (125%) of the sum of Debt Service on Senior Bonds and Debt Service on Subordinated Bonds at that Airport for such Fiscal Year. 8.01.3 Notwithstanding the above, the Airline shall not be required to pay rentals, fees, and charges that are inconsistent with a Surviving Agreement, if any, between the Airline and the Authority. 8.01.4 For purposes of calculating rates for rentals, fees, and charges payable hereunder, the following Direct Cost Centers and Indirect Cost Centers, each as described in Exhibits N-E and D-E, are hereby created: (i) Direct Cost Centers - National (a) Airfield (b) Terminal (c) Aviation (d) Ground Transportation (e) Non-Aviation (f) Equipment (ii) Direct Cost Centers - Dulles (a) Airfield (b) Terminal (c) International Arrivals Building (IAB) (d) Airside Operations Buildings (AOB) (e) Cargo (f) Aviation (g) Ground Transportation (h) Non-Aviation (i) Equipment (j) Passenger Conveyance System (iii) Indirect Cost Centers - National/Dulles (a) Maintenance (b) Public Safety (c) Systems and Services (d) Administrative 8.01.5 For purposes of calculating rates for rentals, fees, and charges payable hereunder, and subject to the provisions of Paragraph 8.03.2, the following Terminal Sub- Centers and Equipment Sub-Centers, each as described in Exhibits N-E and D-E, are hereby created: (i) Terminal and Equipment Sub-Centers - National (a) Main Terminal (Includes Existing North Terminal) (b) Interim Hangar 11 Terminal (c) New North Terminal (ii) Terminal and Equipment Sub-Centers - Dulles (a) Main Terminal (Includes Base-of-Tower Facilities) (b) Existing Midfield Concourses (c) New Midfield Concourse(s) (iii) Additional Equipment Sub-Centers - Dulles (a) International Arrivals Building (IAB) (b) Airside Operations Buildings (AOB) 8.02 Landing Fees. 8.02.1 Calculation of Rates. The Landing Fee rates for each Airport in any Rate Period shall be calculated by dividing each Airport's Airfield Net Requirement by the combined estimated landed weight for all Air Transportation Companies and General Aviation operating at that Airport during the Rate Period. 8.02.2 Rate Schedule. Schedules NF-l (National) and DF-l (Dulles) show the calculation of Landing Fee rates for each Rate Period. 8.02.3 Airline's Landing Fee Charges. Each month the Airline shall pay to the Authority Landing Fees for Chargeable Landings for the preceding month. The Airline's Landing Fees shall be determined as the product of the appropriate Airport's Landing Fee rate for the Rate Period, and the Airline's total landed weight for the month. The Airline's total landed weight at each Airport for the month shall be determined as the sum of the products obtained by multiplying the Maximum Authorized Gross Landed weight of each type of aircraft operated by the Airline at each Airport by the number of Chargeable Landings of each said aircraft operating at that respective Airport during such month. 8.03 Terminal Rentals, Fees, and Charges. 8.03.1 Calculation of Rates. The Terminal Rental rates at each Airport in each Rate Period shall be calculated separately for each Terminal Sub-Center. The rates for each type of space shall be determined in the following Manner: (i) First, for each Terminal Sub-Center at each Airport, the Terminal Sub-Center average rental rates shall be calculated as follows: (a)Each Terminal Sub-Center Net Requirement shall first be divided by total Rentable Space in that Sub-Center to determine that Terminal Sub-Center's average rental rate for the Rate Period; provided, however, the transition adjustments related to the Capital Development Program as set forth in Paragraph 8.03.2 shall be made prior to determining each Terminal Sub-Center's average rental rates. (b)The unadjusted Signatory Airline requirement shall next be determined by multiplying the total amount of Signatory Airline Premises and Common Use Premises in each Terminal Sub-Center, as set forth on Schedules NF-1l and DF-13, times the appropriate Terminal Sub-Center average rental rate. (c)The unadjusted Signatory Airline requirement shall then be reduced by the amount of Transfers, if any, and by the amount, if any, of certain Revenues derived from Surviving Agreements, applicable to each Terminal Sub-Center at each Airport to determine the adjusted amount due from the Signatory Airlines. (d)The adjusted amount calculated in (c) shall then be divided by the total amount of Signatory Airline Terminal Sub-Center Premises and Common Use Premises to determine the Terminal Sub-Center average Signatory Airline rental rate. (ii) To determine the differential Terminal Sub-Center rental rates, each Terminal Sub-Center Premises and Common Use Premises shall first be classified according to the types of space set forth below: Type of Weighted Space Location/Function Value 1 Ticket Counter 1.00 2 Ticket Offices; .90 Administrative and Upper Level Offices; V.I.P. Rooms; Holdrooms 3 Bag Claim; Baggage Service .85 Offices 4 Bag Make-Up; Operations .55 Areas 5 Tug Drives; Exterior .25 Baggage Space 6 Unenclosed Covered Areas (a) (b) 7 Unenclosed Improved (a) (b) Uncovered Areas (a) Rentals for Type 6 and Type 7 space shall be based on initial fixed rates of $4.00 and $1.00, respectively, per square foot, with said rates to be adjusted each Fiscal Year, commencing October 1, 1990, in accordance with changes in the U.S. Implicit Price Deflator Index. The base date for such adjustment shall be the index available on October 1, 1989. (b) If the Airline encloses, or otherwise modifies any such areas, as approved by the Authority, or if the Authority encloses or otherwise modifies any such area(s), the area(s) shall be reclassified into the appropriate space type. The rate for the reclassified space shall be the then current rate for the reclassified space. If the Airline modifies any such area and the rental rate for the reclassified space is higher than it was prior to reclassification, then, at the time the Airline requests approval to modify the space, the Airline and the Authority shall negotiate an appropriate rental credit(s) to reimburse the Airline for any costs incurred by the Airline in modifying such area(s); provided, however, such agreed upon rental credits shall in no event result in ~ rate less than the then current rate for the space prior to its modification. (iii) Next, using the appropriate space totals shown in Schedules NF-11 and DF-13, the Signatory Airline Terminal Sub- Center average rental rate for each Terminal Sub-Center for the Rate Period shall then be converted to differential Terminal Sub- Center rental rates as follows: (a)For each Terminal Sub-Center, the amount of Type 1 through Type 5 space shall be Multiplied by the relative weighted values set forth in Paragraph 8.03.1(ii) above, to obtain a weighted equivalent amount of space. (b)The adjusted Signatory Airline requirement calculated in Paragraph 8.03.1(i)(c), above, shall be reduced by the amount of Type 6 and Type 7 space rentals due for that Rate period, to determine the differential Signatory Airline requirement. (c)For each Terminal Sub-Center, said differential Signatory Airline requirement shall then be divided by the weighted equivalent amount of Premises and Common Use Premises for said Terminal Sub-Center to determine the rate for Type 1 (premium) space. Rates for Types 2 through Type 5 space shall then be determined by multiplying the Type 1 (premium) rate by the relative weighted values for each type of rentable area. 8.03.2 Transition Adjustments. The parties hereto recognize that certain facilities at each Airport, due to construction of the Capital Development Program, are anticipated to be abandoned and/or ultimately demolished in stages during the Period of this Agreement: (i) To the extent any portions of the Existing North Terminal at National are in service during the Period of this Agreement, the following transition adjustments shall be made: (a)The Terminal Sub-Center Net Requirement calculated for National's Main Terminal Sub-Center shall also include the costs attributable to the Existing North Terminal, whether occupied or not, during any Rate Period in which the Existing North Terminal has not yet been demolished; and (b)Rentable Space in the Existing North Terminal used for the calculations in Paragraph 8.03.1 shall include only those areas of the Existing North Terminal actually occupied in each Rate Period. (ii) To the extent any portions of the Base-of-the-Tower Facilities at Dulles are in service during the Period of this Agreement, the following transition adjustments shall be made: (a)The Terminal Sub-Center Net Requirement calculated for the Main Terminal Sub-Center at Dulles shall also include the costs attributable to the Base-of-the-Tower Facilities, whether occupied or not, during any Rate Period in which the Base-of-the-Tower Facilities have not yet been demolished; and (b)Rentable Space in the Base-of-the-Tower Facilities used for the calculations in Paragraph 8.03.1 shall include only those areas of the Base-of-the-Tower Facilities actually occupied in each Rate Period. (iii) To the extent any portions of the Existing Midfield Concourses at Dulles are in service following Substantial Completion of one or more New Midfield Concourse(s) I the following transition adjustments shall be made: (a)The Existing Midfield Concourse Sub-Center Net Requirement shall include the costs attributable to all then remaining portions of the Existing Midfield Concourses, whether occupied or not; and (b)Rentable Space in the then remaining Existing Midfield Concourses used for the calculations in Paragraph 8.03.1 shall include only those areas of the Existing Midfield Concourses actually occupied in each Rate Period. (iv) To the extent that certain areas of each Terminal Sub- Center at either Airport, due to relocations necessitated by the Capital Development Program, may be vacant for temporary periods, the total Rentable Space used for the calculations in Paragraph 8.03.1 at the affected Airport(s) shall be reduced by the amount of such vacated space, whether such temporarily vacated space is that of the Signatory Airlines or other Terminal tenants. (v) Upon Substantial Completion of the New North Terminal at National, the Total Requirement for the Interim Hangar 11 Terminal (related to either its use as a terminal or certain costs related to its conversion from terminal use) shall be included in the calculation of rental rates for the New North Terminal at National. 8.03.3 Rate Schedules. Schedules NF-2, NF-3, and NF-4 (National) and Schedules DF-2, DF-3, and DF-4 (Dulles) show the calculation of average and differential rental rates for each Terminal Sub-Center. 8.03.4 Airline's Terminal Rentals. The Airline's Terminal Rentals for Exclusive, Preferential, and Joint Use Premises in each Rate Period shall be determined as the sum of the products obtained by multiplying the appropriate differential Terminal Sub-Center rental rate for the Rate Period, calculated in accordance with Paragraph 8.03.1, by the amount of the corresponding type of space leased by the Airline in each Terminal Sub-Center at each Airport as Exclusive, Preferential, and Joint Use Premises. Said Terminal Rentals for each Rate Period shall be payable in equal Monthly installments. 8.03.5 Common Use Charges. The Common Use Charges due from Signatory Airlines for Common Use Premises in each Terminal Sub-Center at each Airport in each Rate Period shall be calculated as the product of the appropriate differential Terminal rental rate for the Rate Period and the amount of each category and area of Common Use Premises in each Terminal Sub- Center. Said total Common Use requirement for each Terminal Sub- Center at each Airport shall then be reduced by any amounts for that Rate Period estimated by the Authority (based upon the prior Rate Period's Low Volume Common Use Fees) to be payable as Low Volume Common Use Fees attributable to said Terminal Sub-Center, as set forth in Paragraph 8.03.6, to derive the "net aggregate Common Use requirement." Each Signatory Airline's monthly Common Use Charge, if applicable, for each Airport shall then be determined as follows: (i) Ten percent (10%) of the net aggregate Common Use requirement due in each Terminal Sub-Center (or category or area thereof, if applicable) at each Airport shall be prorated equally among the Signatory Airlines, other than those paying Low Volume Common Use Fees. (ii) The remaining ninety percent (90%) of the net aggregate Common Use requirement due in each Terminal Sub-Center (or category or area thereof, if applicable) at each Airport shall be prorated among the Signatory Airlines, other than those paying Low Volume Common Use Fees, based upon each such Signatory Airline's proportionate share of Total Passengers for all Signatory Airlines, except that the component of the Common Use Charge at Dulles attributable to baggage claim and holdroom shall be calculated on the basis of Total Passengers less the Airline's deplaning passengers using the IAB. (iii) The allocation of Common Use Charges pursuant to Paragraphs (i) and (ii) above, shall be made by the Authority twice each Fiscal Year, with the first such allocation applicable to the six month period commencing on the first day of each Fiscal Year and ending on the last day of the sixth Month of said Fiscal Year, and the second allocation applicable to the remaining six months of said Fiscal Year; provided, however, the Authority shall further have the right to adjust such allocations for the remaining portion of the then current six month period at any other time rates for Common Use Charges are adjusted during a Fiscal Year pursuant to Sections 9.03 or 9.04. At any time such allocations are adjusted, the Authority shall notify the Airline and other Signatory Airlines of the revised allocations, the amounts due from each Signatory Airline, and the period for which such allocations and amounts are applicable, and the Airline shall then pay its allocated share of Common Use Charges in equal monthly installments during said period. Each such allocation shall be based upon activity data for the most recent six months for which such data is then available. (iv) For purposes of the Common Use Charge allocation calculations, the Airline shall include in its monthly activity report required by Section 8.12, and individually identify, the number of Enplaning Passengers and Deplaning Passengers handled or otherwise accommodated by the Airline for other Air Transportation Companies not having an agreement with the Authority that provides for the direct payment to the Authority of appropriate Common Use Charges. 8.03.6 Low Volume Common Use Fees. Notwithstanding the above Paragraph 8.03.5, a Signatory Airline that is a Low Volume Airline shall pay a monthly Low Volume Common Use Fee in lieu of the payment of Common Use Charges, in each Rate Period, for each Airport, calculated as follows: (i) The Common Use requirement for such Rate Period, at such Airport, calculated in accordance with Paragraph 8.03.5 shall be divided by the actual Total Passengers at each Airport for the most recent twelve (12) months for which such activity reports are available. This amount shall be the Low Volume Common Use Fee per Passenger for each Airport. (ii) For each Common Use Charge allocation period as set forth in Paragraph 8.03.5(iii), a Low Volume Airline is a Signatory Airline (a) which operated at that Airport, (b) which operates under Part 135 of the FAA Regulations, and (c) which either reported an average monthly Enplaning Passenger activity level at that Airport less than or equal to one thousand (1,000) Enplaning Passengers per month during the preceding Common Use Charge allocation period, or, if a new Signatory Airline, is projected to generate a monthly average of less than one thousand (1,000) Enplaning Passengers at that Airport for the ensuing Common Use Charge allocation period. (a)In the event that the monthly average Enplaning Passenger activity level of any Signatory Airline paying the Low Volume Common Use Fee becomes greater than one thousand (1,000) Enplaning Passengers at that Airport during the then-current Common Use Charge allocation period, such signatory Airline shall pay Common Use Charges as set forth in Paragraph 8.03.5 in the next ensuing Common Use allocation period. (b)In the event that the monthly average Enplaning Passenger activity level of any Signatory Airline paying Common Use Charges pursuant to Paragraph 8.03.5 (and which operates under Part 135 of the FAA Regulations) becomes less than one thousand (1,000) Enplaning Passengers at that Airport during the then-current Common Use Charge allocation period, such Signatory Airline shall pay the Low Volume Common Use Fee in the next ensuing Common Use Charge allocation period. 8.03.7 Rate Schedules. Schedules NF-5 (National) and DF- 5 (Dulles) show the calculation of Common Use Charges and Low Volume Common Use Fees for each Rate Period. 8.04 Aircraft Parking Position Charges and Dulles Jet Apron Fees. 8.04.1 Aircraft Parking Position Charges at National. The Authority reserves the right to charge the Airline Aircraft Parking Position Charges at National during the Period of this Agreement; provided, however, (i) The Authority shall provide written notice no less than ninety (90) days prior to the effective date of such Aircraft Parking Position Charge; (ii) The Aircraft Parking Position Charge at National shall be calculated in a manner substantially similar to the Aircraft Parking Position Charge at Dulles, as set forth in Paragraph 8.04.2; (iii) The total amount for such charge shall not exceed ten percent (10%) of the Airfield Total Requirement; and (iv) Revenues derived from any such charges shall be applied to reduce the Airfield Total Requirement in any Rate Period in which such charges are imposed and collected by the Authority. 8.04.2 Rates for Ramp Area Charges at Dulles. Dulles Aircraft Parking Position Charges and Dulles Jet Apron Fees ("Ramp Area Charges") shall be calculated, beginning January 1, 1992, as follows: (i) For the initial period commencing January 1, 1992, five percent (5%) of the estimated Airfield Total Requirement shall be the basis of Ramp Area Charges; provided, however, the Authority shall estimate in each subsequent Rate Period the actual requirement attributable to the Ramp Area as a percentage of the Dulles Airfield Total Requirement. Such Authority-estimated Ramp Area requirement for Dulles shall not exceed ten percent (10%) of the Airfield Total Requirement in any Rate Period. (ii) The Ramp Area requirement for Dulles determined as set forth in Paragraph 8.04.2(i) above shall be next divided into Aircraft Parking Position and Dulles Jet Apron components, based upon the number of Aircraft Parking Positions and Dulles Jet Apron positions as a percentage, respectively, of the total of all such aircraft positions at Dulles. (iii) The Aircraft Parking Position requirement determined in Paragraph 8.04.2(u) above in each Rate Period shall be divided by the actual linear footage of all Aircraft Parking Positions (measured one hundred (100) feet from the face of the Terminal or Concourse) in each Rate Period, to determine the Aircraft Parking Position Charge rate. In the event such actual measurement cannot be accomplished, each Aircraft Parking position for a narrow-body aircraft shall be deemed to be one hundred twenty-five (125) linear feet and for a wide-body aircraft shall be deemed to be one hundred seventy-five (175) linear feet. (iv) The Dulles Jet Apron requirement determined in Paragraph 8.04.2(u) above in each Rate Period shall be divided by the estimated number of operations at the Dulles Jet Aprons in each Rate Period to determine the Dulles Jet Apron Fee rate for each operation. (v) In the event that the Authority designates a separate area(s) of the Ramp Area for the shared use by Signatory Airlines operating under Part 135 of the FAA Regulations, then in such event the Authority shall allocate a reasonable amount of the Ramp Area requirement determined as set forth in Paragraph 8.04.2(i) above to such area(s), and shall charge such Airline for the use of said area(s) based upon each such operator's share of total Enplaning Passengers using the area(s). 8.04.3 Airline's Dulles Aircraft Parking Position Charges. At Dulles, the Airline's Aircraft Parking Position Charges, if applicable, shall be the product obtained by Multiplying the total linear footage of the Airline's Aircraft Parking Position(s), as set forth in Exhibit D-B, tiles the Aircraft Parking Position Charge rate for the Rate Period. Such charge shall be paid in equal Monthly installments in accordance with Section 8.11. 8.04.4 Airline's Dulles Jet Apron Fees The Airline's monthly Dulles Jet Apron Fees, if applicable, shall be calculated as the product obtained by multiplying the Dulles Jet Apron Fee rate for the Rate Period by the number of the Airline's aircraft utilizing the Jet Apron to board or disembark passengers during the month; provided, however, the Airline shall not be subject to this Dulles Jet Apron Fee if the Airline pays Aircraft Parking Position Charges directly to the Authority and uses the Dulles Jet Apron exclusively to disembark passengers. An aircraft which both disembarks and boards passengers at a Jet Apron Position will be subject to a single fee. The fee shall be paid monthly in accordance with Section 8.11. 8.05 Equipment Charges. 8.05.1 Equipment Charges. For each Rate Period, the Airline shall pay charges for each type and item of Equipment leased by the Airline from the Authority, if any, as set forth in Exhibits NH and DH. Except as set forth in Paragraph 8.05.2, said charges shall be calculated as the sum of the following: (i) The annual capital requirement for each type and item of Equipment shall be equal to the sum of the Capital Charges plus Debt Service Coverage reduced by Transfers allocable to such Equipment; and (ii) The O&M requirement in each Rate Period for each type and item of Equipment which shall be equal to the O&M Expenses incurred by the Authority and allocable to such Equipment. 8.05.2 The Airline's charges for certain types of Equipment, including baggage claim conveyors and devices, and flight information and baggage information display systems, shall be included in the Airline's Terminal Rentals and Common Use Charges for the Premises and the Common Use Premises in the Terminal Sub-Center in which such Equipment is located. 8.05.3 Equipment Charge Rate Schedules.

Total Passenger Security Reimbursements due and payable at each Airport in each Fiscal Year shall be equal to the Authority's costs of providing security services, including law enforcement officers, for passenger screening. 8.06.2 Airline's Passenger Security Requirements. (i) The Passenger Security Reimbursement requirement shall be allocated among the Signatory Airlines serving each Airport based upon their respective total Enplaning Passengers requiring such services as set forth in Paragraph 8.06.2(u). (ii) The allocation of Passenger Security Reimbursements pursuant to Paragraph 8.06.2(i) shall be made by the Authority twice each Fiscal Year, with the first such allocation applicable to the six month period commencing on the first day of each Fiscal Year and ending on the last day of the sixth month of said Fiscal Year, and the second allocation applicable to the remaining six months of said Fiscal Year; provided, however, the Authority shall further have the right to adjust said allocation for the remaining portion of the then current six month period at any other time the Passenger Security Reimbursements requirement is adjusted during a Fiscal Year pursuant to Sections 9.03 and 9.04. Each such allocation shall be based upon activity data for the most recent six months for which such activity data is then available. (iii) For purposes of such allocations, the Airline shall include in its monthly activity report required pursuant to Section 8.12, and individually identify, the number of Enplaning Passengers handled or otherwise accommodated by the Airline for other Air Transportation Companies not having an agreement with the Authority that provides for the direct payment to the Authority of appropriate charges for Passenger Security Reimbursements. 8.06.3 Passenger Security Reimbursement Schedules. Schedules NF-7 (National) and DF-7 (Dulles) show the calculation of the Passenger Security Reimbursement charges for the current Rate Period. 8.07 International Arrivals Building ("IAB") Charges at Dulles. 8.07.1 IAB Rate. The IAB rate for each Rate Period shall be calculated by reducing the Total Requirement for the IAB by utility and other reimbursements and Transfers, and dividing such amount by the estimated total international Deplaning Passengers using the IAB facility in each Rate Period, to determine the IAB rate per international Deplaning Passenger. 8.07.2 IAB Rate Schedule. Schedule DF-S shows the calculation of the IAB rate for each Rate Period. 8.07.3 Airline's IAB Charges. The Airline's monthly IAB Charge, if any, shall be determined as the product of the IAB rate for the Rate Period and the Airline' 5 international Deplaning Passengers using the facility during the month. 8.08 Airside Operations Building ("AOB") Rentals at Dulles. 8.08.1 AOB Rate. The AOB Rental rate in each Rate Period shall be calculated by reducing the Total Requirement for the AOB by utility and other reimbursements and Transfers, and dividing such net requirement by the total AOB Rentable Space. 8.08.2 AOB Rate Schedule. Schedule DF-9 shows the calculation of the AOB rate for each Rate Period. 8.08.3 Airline's AOB Charges. The Airline's AOB Rentals for each Rate Period, if any, shall be determined as the product of the AOB Rental rate and the number of square feet of AOB Premises leased to the Airline. The Airline shall pay such AOB Rentals in equal monthly installments. 8.09 Passenger Conveyance Charges. 8.09.1 Passenger Conveyance Charges Prior to the Completion of Dulles Stage II. (i) The Total Passenger Conveyance Charges requirement in each Rate Period prior to the completion of Dulles Stage II shall be equal to the Total Requirement for Passenger Conveyances, reduced by Transfers allocable to Passenger Conveyances and by mobile lounge fees, if any, received by the Authority from non- Signatory Airlines.

(b) The remainder of such component shall be allocated to the Total Requirement for each Terminal Sub-Center served by said system, based upon the respective Rentable Space in each such Terminal Sub-Center. (c) Notwithstanding the foregoing1 if the Inter-Terminal and IAB People Mover Train does not serve the IAB, no portion of the Inter-Terminal and IAB People Mover component shall be allocated to the IAB. 8.10 Other Fees and Charges. 8.10.1 The Authority expressly reserves the right to assess and collect the following: (i) Reasonable and non-discriminatory concession, permit or license fees for services or supplies provided by the Airline to others, and by others to the Airline.

Such services or facilities may include, but are not limited to, maintenance of Airline Premises, when such maintenance is requested by the Airline or is the responsibility of the Airline pursuant to this Agreement, directly metered utility costs and other O&M Expenses, if any, related to Equipment. 8.10.4 The Airline shall pay the required fees for all permits and licenses necessary for the conduct of its Air Transportation Business at the Airport. The Airline shall also pay all taxes and assessments, which during the Period of this Agreement may become a lien or which may be levied by any governmental authority upon any taxable interest acquired by the Airline in this Agreement, or any taxable possessory right which the Airline may have in or to the Premises or facilities leased hereunder, or the improvements thereon, by reason of its occupancy thereof, or otherwise, as well as taxes on taxable property, real or personal, owned by the Airline in or about said Premises.

Further, this provision shall not be construed as precluding the Authority from pursuing any other remedies it may have for the Airline's default in the payment of its rentals, fees, or charges, from executing against or requiring the Airline to furnish Contract Security pursuant to Section 8.13, or from exercising any other rights contained herein or provided by law. 8.11.5 In the event the Airline fails to submit its monthly activity reports as required in Section 8.12 the Authority may, in its discretion, estimate the fees and charges due and payable by the Airline as set forth in Paragraph 8.11.2, based upon one hundred twenty-five percent (125~) of the monthly activity reported by the Airline for the next preceding month and issue an invoice to the Airline for said estimated amount, less amounts, if any, already received from the Airline for rentals, fees, and charges due for such month for which complete activity data has not been received by the Authority. The Airline agrees to pay said estimated amount and to be liable for any deficiencies in payments based on this estimate, plus interest, as set forth in Paragraph 8.11.4 above. If such estimate results in an overpayment by the Airline, and (i) if the Airline submits the delinquent activity report to the Authority within 30 days of the original date due, then the Authority shall credit the Airline's subsequent month's amount due for such overpayment less adjustment for applicable interest charges, if any, as set forth in Paragraph 8.11.4; or (ii) if the Airline does not submit the delinquent activity report to the Authority within thirty (30) days of the original date due, the Authority shall have the right to retain any such overpayment.

Unless otherwise specified in writing by the Authority, the report shall be delivered to: Metropolitan Washington Airports Authority Office of Air Carrier Affairs 44 Canal Center Plaza Alexandria, Virginia 22314 8.12.2 The Authority shall have the right to rely on said activity reports in determining rentals, fees, and charges due hereunder; provided, however, the Airline shall have full responsibility for the accuracy of said reports. Payment deficiencies due to incomplete or inaccurate activity reports shall be subject to interest charges as set forth in Paragraph 8.11.4. Notwithstanding the foregoing, upon receipt of complete, accurate reports, overpayments, if any, shall be credited by the Authority against the Airline's subsequent month's amount due. 8.12.3 The Airline agrees, at all times, to maintain and keep books, ledgers, accounts or other records, accurately reflecting all of the entries for the activity statistics to be reported pursuant to Paragraph 8.12.1. Such records shall be retained by the Airline for a period of three (3) years subsequent to the activities reported therein. The Airline agrees to produce such books and records for the Authority at the Authority's place of business within fifteen (15) calendar days of the Authority's notice to do so or, at a location of the Airline's choosing, in which case the Airline shall pay all reasonable expenses, including, but not limited to, transportation, food, and lodging, necessary for an auditor selected by the Authority to audit said books and records. 8.12.4 The cost of the audit, with the exception of the aforementioned expenses, shall be borne by the Authority; provided, however, the total cost of said audit shall be borne by the Airline if either or both of the following conditions exist: (i) The audit reveals an underpayment of the lesser of one hundred thousand dollars ($100,000) or five percent (5%) of rentals, fees, and charges due hereunder, as determined by said audit; and/or (ii) The Airline has failed to maintain accurate and complete books, accounts, and other records in accordance with Paragraph 8.12.3. 8.13 Security for Payment. 8.13.1 If at any time during the twelve (12) consecutive months immediately preceding the Effective Date of this Agreement, the Airline committed an act or omission that constituted a default in payments due to the Authority pursuant to the terms and provisions of the Prior Agreements and Leases, then the Authority has the right to require the Airline to provide to the Authority on the Effective Date, payment of outstanding default amounts, if any, and a surety bond, irrevocable letter of credit or other security acceptable to the Authority ("Contract Security") in an amount equal to an estimate of four (4) months' rentals, fees, and charges payable by the Airline pursuant to this Article 8. Such Contract Security shall be for the purpose of guaranteeing the payment of all rentals, fees, and charges due hereunder. If Contract Security is required by the Authority, the Airline shall maintain such Contract Security in effect until the expiration of twelve (12) consecutive months during which period the Airline commits no act or omission that would constitute a payment default pursuant to Paragraph 13.01.9 of this Agreement. Such Contract Security shall be in such form and with such company approved to do business in the Commonwealth of Virginia as shall be reasonably acceptable to the Authority. 8.13.2 Upon the failure of the Airline to make a payment on or before the date due, as prescribed in Section 8.11, and the continued failure by the Airline to make payments within five (5) calendar days after the date of written notice from the Authority of such failure to pay, the Authority, within thirty (30) days of the date of the written notice, shall have the right to impose or reimpose the requirements of Paragraph 8.13.1, above, on the Airline. In such event, the Airline shall provide the Authority with the required Contract Security within fourteen (14) days from its receipt of such written notice that the Authority is imposing or reimposing such Contract Security requirement and maintain said security in effect until the expiration of a period of twelve (12) consecutive months during which the Airline makes all payment, to the Authority as required by Section 8.11 herein when due. The Authority shall have the right to reimpose the requirements of Paragraph 8.13.1, above, on the Airline each time the Airline fails to make a payment as required by Section 8.11 during the Period of this Agreement. The Authority's rights under this Paragraph 8.13.2 shall be in addition to all other rights and remedies available to the Authority either by law or under the terms of this Agreement. 8.14 Rentals, Fees, and Charges During Construction of the Capital Development Program. 8.14.1 The rentals, fees, and charges payable by the Airline to the Authority, and the rates for such rentals, fees, and charges, may be recalculated and increased or decreased a~ appropriate, effective as of each Substantial Completion Date of any Project included in the Capital Development Program to the extent that the costs allocable to such Project, or a portion thereof, are allocable to the Airline Supported Areas; provided, however, the Authority may include in any rate adjustment made pursuant to Sections 9.02 and 9.03 the Capital Charges, Debt Service Coverage, O&M Expenses, and all other payments and reserves for any such Project anticipated by the Authority to become payable from Revenues during the next ensuing Rate Period. 8.14.2 Upon the Substantial Completion Date of any Premises and until the actual square footage of such Premises has been incorporated into revised Exhibits N-C-2 and D-C-2, all determinations that are based on the dimensions of the Premises, including rentals, fees, and charges, shall be based on the approximate dimensions stated in Exhibits N-C-l and D-C-l. After the incorporation of the actual square footage, the rentals, fees, and charges that are determined by the dimensions of the Premises shall be calculated using the actual square footage, and amounts previously paid or owed by the Airline shall be adjusted retroactively to the Substantial Completion Date. After the retroactive adjustment, the Airline shall pay to the Authority, together with the payment for the next monthly period, any additional rentals, fees, and charges that are due to the Authority or the Authority shall credit the Airline with any rentals, fees, and charges that were overpaid by the Airline so that the total payment made by the Airline for the period beginning with the Substantial Completion Date and ending with the date of the adjustment shall be the amount the Airline would have paid if the rentals, fees, and charges had been calculated on the actual square footage from the Substantial Completion Date. 8.14.3 In the event that Debt Service and Debt Service Coverage applicable to any Project in a Cost Center or Sub-Center within any Airline Supported Area shall become payable from Revenues prior to the Substantial Completion Date of said Project, the Total Requirement for such Cost Center or Sub-Center shall include such Debt Service and Debt Service Coverage from such earlier date. 8.15 Passenger Facility Charges. in the event that passenger facility charges, now precluded by 49 U.S.C. 1513(a), are by legislative enactment, regulatory action, or by an adjudication by a court of competent jurisdiction determined to be lawful for the Authority to assess and collect during the Period of this Agreement, the Authority hereby reserves the right to assess, collect and expend such charges, subject to any conditions and restrictions expressly provided by such legislation or regulation. 8.16 No Other Fees and Charges. Except as provided for in this Agreement or any other contract between the Airline and the Authority, no charges, fees, or tolls of any nature, direct or indirect, shall be imposed by the Authority upon the Airline, its employees, agents, passengers, guests, patrons, and invitees, its suppliers of materials, or furnishers of services; provided, however, and except as otherwise provided herein, that the foregoing shall not be construed to prohibit the Authority from imposing and collecting charges and fees for the use of the public auto parking areas on the Airports, from operators of ground transportation to, from, and on the Airports and from any concessionaire at the Airports in accordance with the terms of a contract with the Authority for the operation of such concession. 8.17 1990 Fiscal Year Adjustment. In consideration for the Authority's agreement to refrain from exercising its right under Prior Agreements and Leases to impose new rates and charges on the Airline effective as of October 1, 1989, and instead, deferring the effectiveness of said new rates and charges to January 1, 1990, the rates and charges in effect for the period January 1, 1990, through September 30, 1990, will include an amount that represents the difference, during the period from October 1, 1989, to December 31, 1989, between the amount of the rates and charges then in effect and the amount that would have been charged to the Airline if the rates and charges under this Agreement had been made effective on October 1, 1989. ARTICLE 9. CHANGES IN RATES FOR RENTALS, FEES, AND CHARGES 9.01 General. 9.01.1 Rates for Signatory Airlines' rentals1 fees, and charges shall be adjusted as set forth in this Article 9. Said adjusted rates shall become effective (i) on the first day of each Fiscal Year pursuant to Section 9.02 ("Annual Adjustment"); (ii) on the first day of the seventh month of each Fiscal Year, if adjusted pursuant to Section 9.03 ("Midyear Adjustment"); or (iii) at any other time pursuant to Section 9.04. 9.01.2 Beginning on the effective date of a Rate Period following each such adjustment as provided for herein and for the duration of that Rate Period, unless said rates are subsequently adjusted during a Fiscal Year pursuant to Section 9.03 or 9.04, the Airline's rentals, fees, and charges payable to the Authority hereunder shall be based upon the rates as adjusted. 9.01.3 All adjustments made pursuant to this Article 9 shall be determined by the Authority and provided to the Airline substantially in conformance with the methods set forth in Article 8. Upon each adjustment, revised Schedules NF-l through NF-l1 and DF-1 through DF-14, showing the calculation of adjusted rates for rentals, fees, and charges for that Rate Period shall be prepared by the Authority and transmitted to the Airline, and said rates shall apply without the necessity of formal amendment of this Agreement. 9.01.4 If the calculation of adjusted rates for the next ensuing Rate Period is not completed by the Authority or the notice to the Airline of said adjusted rates as required herein is not given on or before twenty (20) calendar days prior to the end of the then current Rate Period, the rates for rentals, fees, and charges then in effect shall continue to be paid by the Airline until such calculations are concluded and such twenty (20) day notice is given. Upon the conclusion of such calculations and the giving of such twenty (20) day notice, the Authority shall determine the difference(s), if any, between the actual rentals, fees, and charges paid by the Airline to date for the then current Rate Period and the rentals, fees, and charges that would have been paid by the Airline if said adjusted rates had been in effect beginning on the first day of the then current Rate Period. Said differences shall be applied to the particular rentals, fees or charges for which a difference(s) in rates resulted in an overpayment or underpayment, and shall be remitted by the Airline or credited by the Authority in the month immediately following the calculation of the new Rate Period rates and the giving of notice to Signatory Airlines. 9.02 Annual Adjustment. 9.02.1 Approximately sixty (60) days prior to the end of each Fiscal Year, the Authority shall notify the Signatory Airlines of the estimated rates for rentals, fees, and charges for the next ensuing Fiscal Year. Said rates shall be based upon estimated activity at each Airport, budgeted O&M Expenses, the estimated Transfers amount required by this Agreement, Capital Charges, Debt Service Coverage, Lease payments, and all other payments and reserves as set forth in Exhibits N-F and D-F, for the next ensuing Fiscal Year. 9.02.2 Within twenty (20) days after the forwarding of said estimated rates for rentals, fees, and charges, the Authority shall meet collectively with the Signatory Airlines of each Airport at a mutually convenient time for the purpose of discussing such estimated rates for rentals, fees, and charges. The Authority shall make available to the Signatory Airlines any reasonably requested additional information relating to the determination of the proposed rates. The Authority agrees to fully consider the comments and recommendations of the Signatory Airlines prior to finalizing its schedule of estimated rates for rentals, fees, and charges for the next ensuing Fiscal Year. 9.02.3 Following said meeting, the Authority shall provide at least twenty (20) days advance written notice to the Signatory Airlines of the estimated rates for rentals, fees, and charges in accordance with this Section 9.02, and subject to the provisions of Paragraph 9.01.4, such adjusted rates shall become effective on the first day of the next ensuing Fiscal Year. 9.03 Midyear Adjustment. 9.03.1 In addition to the provisions of Sections 9.02 and 9.04, the Authority shall have the right to adjust the estimated rates for rentals, fees, and charges payable by the Signatory Airlines at the midpoint of each Fiscal Year in accordance with this Section 9.03. 9.03.2 Approximately sixty (60) days prior to the end of the sixth month of the then current Fiscal Year, the Authority shall re-estimate the rates for rentals, fees, and charges payable hereunder, applicable to the last six months of the then current Fiscal Year, and shall then determine in accordance with Paragraph 9.03.5 whether a midyear adjustment to any rate(s) will be made. Said re-estimated rates shall be based upon any adjustment to Transfers required by this Agreement based upon the actual audited results for the preceding Fiscal Year and revised estimates of activity, 0&M Expenses, Capital Charges, Debt Service Coverage, and all other payments and reserves, as set forth in Exhibits N-F and D-F, for the then current Fiscal Year. 9.03.3 In the event midyear adjustments to rates are made by the Authority, the Authority shall notify the Signatory Airlines of the re-estimated rates approximately forty-five (45) days prior to the end of the sixth month of the then current Fiscal Year. Within twenty (20) days after the forwarding of said rates, the Authority shall, if requested by the Airline or another Signatory Airline, meet collectively with the Signatory Airlines at each Airport at a mutually convenient time for the purpose of discussing said re-estimated rates. The Authority shall make available to the Signatory Airlines any reasonably requested additional information relating to said rates. The Authority agrees to fully consider the comments and recommendations of the Signatory Airlines prior to finalizing the midyear adjusted rates. 9.03.4 Following said meeting, the Authority shall provide at least twenty (20) days advance written notification to the Signatory Airlines of the adjusted rates to become effective on the first day of the seventh month of the then current Fiscal Year, subject to the provisions of Paragraph 9.01.4. 9.03.5 Nothing in this Section 9.03 shall be construed to require that the Authority make a midyear adjustment to estimated rates at either Airport; provided further that the Authority shall not make any such midyear adjustment to any rate at an Airport if the total of rentals, fees, or charges payable by the Signatory Airlines at that Airport, using the then current rates for rentals, fees, and charges at that Airport, is at least ninety-eight percent (98%) of the total of rentals, fees, or charges that would be payable by the Signatory Airlines using any re-estimated rate(s) calculated pursuant to this Section 9.03. 9.03.6 In the event that the Authority does not make a midyear adjustment to rates, any difference between the estimated Transfers amount included in the calculation of the then current rates, and the amount of Transfers actually due to the Signatory Airlines based upon the audited results for the preceding Fiscal Year, may at the option of the Authority (i) be included in any subsequent adjustment of rates during the then current Fiscal Year, as provided for in Section 9.04; or (ii) be incorporated into the settlement calculations for the then current Fiscal Year as provided for in Section 9.07. 9.04 Other Rate Adjustments. 9.04.1 Notwithstanding the provisions of Sections 9.02 and 9.03, any rate for rentals, fees, or charges payable by the Signatory Airlines at an Airport may be adjusted by the Authority at any other time in the event of one or more of the following: (i) Current year-to-date unaudited financial data and/or activity statistics indicate that total rentals, fees, and charges payable at an Airport pursuant to the then current rates are projected by the Authority to vary by more than five percent (5%) from the total rentals, fees, and charges that would be paid during the Rate Period at that Airport if rates were based upon more current financial and activity data then available. (ii) The Indenture requires such an adjustment; provided, however, that total rentals, fees, and charges payable to the Authority by Signatory Airlines shall be calculated in accordance with this Agreement. (iii) Additional Projects are constructed in Airline Supported Areas, and Debt Service and/or Amortization Requirements for such Additional Projects become payable from Revenues on a date other than the first day of any Fiscal Year; provided, however, the Authority may include in any rate adjustments made pursuant to Sections 9.02 and 9.03 the Capital Charges, O&M Expenses, and all other payments, Debt Service Coverage, and reserves required by this Agreement for any such Additional Project, the costs of which are anticipated by the Authority to become payable from Revenues (as opposed to capitalized interest) during the next ensuing Rate Period. (iv) At any other time as provided for in this Agreement, including, but not limited to, adjustments made in accordance with Section 8.14 for Projects included in the Capital Development Program. 9.04.2 The Authority shall provide at least twenty (20) days advance written notice to the Signatory Airlines of changes to estimated rates made in accordance with this Section 9.04, including the reasons necessitating any such adjustment, and such adjusted rates shall become effective on the date specified in the Authority's written notice to the Airline, subject to the provisions of Paragraph 9.01.4. 9.05 Transfers. 9.05.1 At the conclusion of each Fiscal Year, the amount of any "Net Remaining Revenue" at each Airport, as such term is defined in Paragraph 9.05.2, shall be determined. For each Fiscal Year during the Period of this Agreement such Net Remaining Revenue shall be allocated between the Authority and the Signatory Airlines at that Airport in accordance with provisions of Paragraph 9.05.4. For the first Fiscal Year immediately following the expiration or earlier termination of this Agreement, such Net Remaining Revenue shall be allocated in accordance with the provisions of Paragraph 9.05.6. The Signatory Airlines' share (hereinafter called "Transfers") of Net Remaining Revenue for each Fiscal Year shall be transferred by the Authority from the General Purpose Fund to the Airline Transfer Account at the beginning of the next ensuing Fiscal Year. Amounts in the Airline Transfer Account shall be applied as credits in the calculation of Signatory Airline rates for rentals, fees, and charges in such next ensuing Fiscal Year. The Authority's share of Net Remaining Revenue shall be transferred by the Authority from the General Purpose Fund to the Authority Capital Fund at the beginning of such next ensuing Fiscal Year, and used for the purposes described in Section 9.06. 9.05.2 For any Fiscal Year, Net Remaining Revenue at each Airport is hereby defined to mean the total of Revenues for such Fiscal Year plus Transfers, if any, from the prior Fiscal Year less (i) O&M Expenses; (ii) required deposits to maintain the O&M Reserve; (iii) Debt Service; (iv) Federal Lease payment; (v) the amount of rental credits given to certain Scheduled Air Carriers as set forth in the Surviving Agreements; (vi) required deposits to any Debt Service Reserve Fund; and (vii) required deposits to the Emergency R&R Fund; all as calculated in accordance with Schedules NF-8 and DF-l0 for the then current Fiscal Year. 9.05.3 When estimating the rates for rentals, fees, and charges for the next ensuing Fiscal Year, as set forth in Section 9.02, the Authority shall also estimate for each Airport the Transfers required by this Agreement to be transferred from Net Remaining Revenue generated at each Airport in the then current Fiscal Year. Said estimated required Transfers at each Airport shall be allocated to the Cost Centers and Sub-Centers at that Airport in the manner described in Paragraph 9.05.4, and included as a credit in the calculation of rates for Signatory Airlines' rentals, fees, and charges for the next ensuing Fiscal Year. 9.05.4 Net Remaining Revenue at each Airport for each Fiscal Year shall be allocated between the Signatory Airlines and the Authority and the Signatory Airlines' share shall be allocated to Airline Supported Areas at each Airport as follows: (i) An amount equal to the entire amount of the Depreciation Requirement collected from the Signatory Airlines for such Fiscal Year shall be allocated to the Authority; (ii) An amount equal to the entire amount of Airline Funded Coverage on Subordinated Bonds (or if any such Bonds have been refunded from the proceeds of Senior Bonds, then the entire amount of Airline Funded Coverage on such Senior Bonds) collected from the Signatory Airlines for such Fiscal Year shall be allocated to the Airline Supported Areas in direct proportion to the allocation of Debt Service on Subordinated Bonds (or Senior Bonds, if any, issued to refund Subordinated Bonds) to the Cost Centers and Sub-Centers within the Airline Supported Areas; (iii) An amount equal to the entire amount of any Extraordinary Coverage Protection Payments, as described in Paragraph 9.07.3, shall be allocated to Airline Supported Areas in direct proportion to the Total Requirements of each of the Cost Centers and Sub-Centers within the Airline Supported Areas. (iv) An amount equal to the entire amount of Equipment Coverage collected from the Signatory Airlines for such Fiscal Year shall be allocated to the Equipment Sub-Centers in direct proportion to the allocation of Debt Service to such Sub-Centers. (v) An amount equal to the excess of Net Remaining Revenue for such Fiscal Year over the sum of the amounts described in (i), (ii), (iii), and (iv) above shall be divided between the Signatory Airlines and the Authority as follows: (a)Such amount for each Airport shall be divided equally between the Signatory Airlines and the Authority until the Authority's share under this Paragraph (v) for that Airport is equal to the Plateau Amount for that Airport for that Fiscal Year; (b)Once the Authority's share of Net Remaining Revenue has reached the Plateau Amount for an Airport for such Fiscal Year, the Signatory Airlines' share of any additional Net Remaining Revenue at that Airport shall equal seventy-five percent (75%) and the Authority's share shall equal twenty-five percent (25%); (vi) The Signatory Airlines' share of Net Remaining Revenue determined pursuant to Paragraph (v) above shall be allocated to the Airline Supported Areas as follows: (a)An amount equal to fifty percent (50%) of the amount of Airline Funded Coverage on Debt Service on Senior Bonds collected from the Signatory Airlines for such Fiscal Year shall be allocated to the Airline Supported Areas in proportion to the allocation of Debt Service on Senior Bonds to the Cost Centers and Sub-Centers within the Airline Supported Areas; (b)The remainder shall be allocated to the Airline Supported Areas in proportion to the Total Requirements (for purposes of this allocation only, Total Requirements shall include one hundred twenty-five percent (125%) of any Special Facility Bond debt service attributable to facilities in the Airline Supported Areas which are reasonably entitled pursuant to Paragraph 10.01.3 and the terms of any Special Facility agreement to the benefit of Transfers) of each of the Cost Centers and Sub- Centers within the Airline Supported Areas. 9.05.5 The Authority shall credit Transfers only from funds available for such purposes in the General Purpose Fund. If for any reason the amount in the General Purpose Fund available for Transfers to the Signatory Airlines pursuant to this Agreement is less than the amount required to be credited to the Signatory Airlines pursuant to Paragraph 9.05.4, the Authority shall make appropriate increases in Transfers from available funds in subsequent Fiscal Years. 9.05.6 Net Remaining Revenue for the last Fiscal Year during the Period of this Agreement shall be allocated either (i) in accordance with the terms of any subsequent airport use agreement entered into between the Authority and some or all of the Signatory Airlines, or (ii) in the absence of such agreement, between the Authority, on the one hand, and the airlines then operating at the Airports on the other hand, substantially in accordance with the methodology set forth in this Agreement except with respect to any distinctions made herein between Signatory Airlines and non-Signatory Airlines. 9.06 Creation of Funds and Accounts. Authority Capital Fund - The Authority shall create a fund to be entitled the Authority Capital Fund into which the Authority shall transfer its share of Net Remaining Revenue calculated in accordance with Section 9.05.

The Authority and the Airlines recognize that, at the time of preparation and distribution for execution of this Agreement, the Authority has no current intention to participate in the capital or operating costs of a Rail System. The Authority will, however, be supportive of efforts of those outside the Authority to provide a Rail System to the Airport and will use its best efforts to accommodate a Rail System on the Airport. The Authority and the Airlines have mutual concerns regarding potential financial impact of future proposals or decisions relating to a Rail System. In view of these concerns, it is agreed as follows: (i) No operating or maintenance costs associated with any Rail System may be incurred by the Authority and/or paid for from any source of funds other than the Authority's Capital Fund unless and until such costs are addressed and mutually resolved in a written agreement between the Majority-in-Interest of the Signatory Airlines at Dulles for the Airfield Cost Center and the Authority. (ii) Any capital costs in excess of ten million dollars ($10,000,000), and all operating costs that may ultimately be incurred by the Authority as a result of its accommodation of or participation in a Rail System will be addressed in an agreement between the Majority-in-Interest of the Signatory Airlines at Dulles for the Airfield Cost Center and the Authority. The negotiation of such an agreement will commence at least six (6) months prior to the Authority's Fiscal Year in which such costs would be incurred with the objective of reaching an agreement not less than sixty (60) days prior to such Fiscal Year. (iii) In the absence of such an agreement, the aggregate of all capital costs of any rail link to Dulles which the Authority may incur is ten million dollars ($10,000,000) over the Period of this Agreement and all costs shall be allocated to the Dulles ground transportation cost center. 11.3 ARTICLE 11. DAMAGE AND DESTRUCTION TO PREMISES; INSURANCE 11.01 The Authority's Responsibilities. 11.01.1 The Authority shall maintain insurance or cause insurance to be maintained with a responsible insurance company or companies approved to do business in the Commonwealth of Virginia, or adopt and maintain a risk financing plan for property losses and said insurance, plan, or combination thereof shall cover such risks as are ordinarily insured against by reasonably prudent operators of airports, including the insurance required by the Indenture, and further, including, without limiting the generality of the foregoing, fire, lightning, windstorm, hail, floods, explosion, riot, riot attending a strike, civil commotion, damage from aircraft, smoke and uniform standard extended coverage with vandalism and malicious mischief endorsements, coverage of demolition of buildings and removal of debris, all-risk coverage, business interruptions, and extra expense. Such insurance or plan shall be maintained in an amount not less than the full insurable replacement value. Full insurable replacement value of any insured improvement shall be deemed to equal the actual replacement cost of the improvement and shall be determined by the Authority from time to time, but not less frequently than once every three years. In the event that such determination of full insurable replacement value indicates that the improvements are underinsured, the Authority shall secure the necessary additional coverage. 11.01.2 If a portion of the Airports within the Airline Supported Areas, except property for which the Airline is responsible under Section 11.02, is damaged or destroyed by fire or other peril, and except for TAP or as provided elsewhere in this Article 11, the Authority after consultation with the Airline, shall, to the extent of proceeds of the Authority's property insurance paid to the Authority or self insurance, repair, reconstruct, and replace the damaged or destroyed improvements so that the Airports are returned substantially to the same condition, character, and utility value (based upon the plans and specifications for the Premises, subject to the then- existing Airport building standards) as existed prior to such damage or destruction, exclusive of improvements made by the Airline and Airline Operating Facilities. With respect to TAP, the Authority shall so repair, reconstruct, and replace damaged or destroyed TAP to the extent suitable to the conduct of the Airline's Air Transportation Business or provide alternative suitable Premises. 11.02 The Airline's Property Insurance Responsibilities. 11.02.1 The Airline shall be primarily responsible for insuring its Airline Operating Facilities and for insuring the property for which it has responsibility in accordance with a Surviving Agreement. The Authority shall be an additional named insured on policies for the insurance of the Airline's Premises. 11.02.2 The insurance for Airline Operating Facilities and property required by Paragraph 11.02.1 shall be in an amount equal to the full replacement value thereof. This insurance shall include the following coverages at a minimum fire, lightning, windstorm, hail, floods, explosion, riot, riot attending a strike, civil commotion, damage from aircraft, smoke and uniform standard extended coverage with vandalism and malicious mischief endorsements, coverage of demolition of buildings and removal of debris, all-risk coverage, business interruptions, and extra expense. 11.03 Rental Abatement. 11.03.1 If the Premises or Equipment, or any portion thereof, are rendered untenantable by reason of damage or destruction, other than damage or destruction described in Paragraph 11.03.2, the Airline shall be entitled to a pro rata abatement of rentals, based upon size and type of area rendered untenantable, until the Premises or Equipment are restored; provided, however, that the Airline shall not be entitled to any such abatement of rentals at any time if the rate covenant under the Indenture is not at such time being met, or if such abatement would cause the rate covenant to be violated, or if such abatement would prevent the Authority from complying with any additional bonds test under the Indenture. 11.03.2 Notwithstanding any other provisions of this Article 11, if the Premises or Equipment shall be damaged or destroyed by fire or other peril, due to the negligence or willful act or omission of the Airline, its officers, its employees acting within the course and scope of their employment, its agents, or licensees, the Airline shall not be entitled to any rental abatement. 11.04 Responsibilities if Damage or Destruction Occurs. 11.04.1 The Authority shall use its best efforts to provide the Airline with alternative Premises and Equipment during the period that its Premises and Equipment are damaged or destroyed and are untenantable or unusable. Said alternative Premises or Equipment shall be suitable for the conduct of the Airline's Air Transportation Business, but shall not be construed to require alternative Premises and Equipment that are comparable to the size1 location, access, or other features of the Premises or Equipment leased under Article 6. 11.04.2 The Airline shall pay rentals, fees, and charges in accordance with Article 8 for any alternative Premises and Terminal Equipment used or leased by it during the period of repair and reconstruction of the original Premises. ARTICLE 12. THIRD PARTY OBLIGATIONS; INDEMNIFICATION AND INSURANCE 12.01 Indemnification. The Airline shall defend, indemnify, and hold the Authority and its agents, officers and employees completely harmless from and against any and all claims, suits, demands, actions, liabilities, losses, damages, judgments, or fines arising by reason of injury or death of any person, or damage to any property, including all reasonable costs for investigation and defense thereof (including, but not limited to, attorney fees, court costs and expert fees) of any nature whatsoever arising out of the Airline's conduct of its Air Transportation Business on the Airports, or in its use or occupancy of the Premises, regardless of where the injury, death, or damage may occur, except to the extent such injury, death, or damage is caused by the negligent act or omission or willful misconduct of the Authority. The Authority shall give to the Airline reasonable notice of, and an opportunity to defend against, any such claims or actions, and the Authority shall take reasonable actions to mitigate its damages. 12.01.1 The Airline shall defend, indemnify, and hold the Authority, and its agents, officers, and employees, completely harmless from and against any claim, suit, demand, action, liability, loss, damage, judgment, fine, or civil penalty and all costs and expenses of whatever kind or nature (including, but not limited to, attorney fees, court costs, and expert fees) associated therewith in any way arising from or based upon the violation of any Federal, state, or municipal laws, statutes, resolutions, or regulations by the Airline, its agents, employees, contractors, or tenants, in conjunction with the Airline's use and/or occupancy of the Airport. The Authority shall give the Airline reasonable notice of, and an opportunity to defend against, any such claims or actions, and the Authority shall take reasonable actions to mitigate its damages. 12.01.2 If the Authority is deemed to be in noncompliance with laws or regulations governing access to secure areas of the Airport and to the areas of the Airfield and said non-compliance is the result of or due to the negligence or willful act or omission of the Airline or of any of the Airline's employees, agents, or contractors and such breach results in a civil penalty action against the Authority, the Airline agrees to reimburse the Authority for all expenses, including reasonable attorney fees, incurred by the Authority in defending against the civil penalty action and for any civil penalty or settlement amount paid by the Authority as a result of being deemed in non-compliance. The Authority shall give the Airline reasonable notice of any allegation, investigation, or proposed or actual civil penalty sought for such non-compliance. 12.01.3 The provisions of this Section 12.01 shall survive the expiration, termination, or early cancellation of this Agreement for claims, suits, demands, actions, liabilities, loss, or damage, which occur prior to the termination or early cancellation of this Agreement. 12.02 Required Insurance Coverage. The Airline, at its sole cost and expense, shall throughout the Period of this Agreement, keep all of its operations on the Airports, and its obligation to indemnify the Authority pursuant to Section 12.01, continuously and fully insured in accordance with this section of this Agreement. The minimum amounts and types of insurance coverage required hereunder shall in no event be construed to limit or modify the Airline's obligation to indemnify the Authority as set forth in Section 12.01. 12.02.1 Airline Liability Insurance This insurance shall be maintained in respect of all aircraft owned, leased or operated by the Airline for bodily injury or death and property damage liability in a combined single limit amount of not less than two hundred million dollars ($200,000,000) per occurrence and shall include aircraft liability, airport liability, passenger liability and baggage and cargo liability. Provided, however, if the Airline operates at the Airports only as a Regional/Commuter Air Carrier, the Airline shall maintain aircraft liability insurance in a combined single limit amount of not less than fifty million dollars ($50,000,000) per occurrence. A twenty-five million dollars ($25,000,000) per occurrence sub- limit for personal injury, bodily injury (including death) and property damage liability shall cover premises-operation, medical payments, contractual liability, liability of independent contractors, personal injury, and fire legal liability. If the Airline operates a club or "VIP" room serving alcoholic beverages, liquor liability insurance must be provided. 12.02.2 Comprehensive Automobile Liability Insurance. This insurance shall cover owned, hired, and nonowned vehicles against death, bodily injury, and property damage claims, in a combined single limit amount of not less than five million dollars ($5,000,000). 12.02.3 Workers' Compensation and Employers' Liability. This insurance shall provide Virginia Statutory Limits with an All States Endorsement and one million dollars ($1,000,000) in Employer's Liability coverage. 12.03 Insurance Companies; Certificates; Self Insurance; Review of Coverage. 12.03.1 All insurance shall be in a form and with an insurance company or companies that is reasonably acceptable to the Authority, and, if a domestic insurer, rated B+10 or better under the Best rating system. Said insurance shall be in occurrence form, not claims made. 12.03.2 On or before the Effective Date, an original Certificate or Certificates of Insurance shall be transmitted to the Authority providing evidence that the required insurance coverage has been procured by the Airline and is in effect on the Effective Date in the types and amounts required by this Article. Said Certificate(s) shall clearly list the Metropolitan Washington Airports Authority as an additional named insured on the liability policies with respect to the Airline's indemnity obligation under Section 12.01. Further, said Certificate(s) of Insurance shall unequivocally provide thirty (30) days advance written notice to the Authority prior to any material change, cancellation, or non-renewal of coverage thereunder. The Certificate(s) shall be signed by, or bear the facsimile of, a representative of the insurance company authorized to bind that company. 12.03.3 All insurance policies required hereunder may be written to include a reasonable retention or deductible. Said retention or deductible shall be subject to the approval of the Authority which approval shall not be unreasonably withheld. 12.03.4 Notwithstanding anything to the contrary in this Article, the Authority will allow the insurance coverage required by Section 12.02 herein to be provided through a self-insurance plan established by the Airline; provided that the self-insurance plan may consist of a combination of primary, excess umbrella insurance and a self-insured retention, and the total of insurance and self insurance protection is no less than the limits stated in this Article. The self-insurance plan must be approved in writing by the Authority prior to becoming effective at the Airports. An Airline requesting the Authority's approval of a self-insurance plan must submit a copy of its self-insurance plan, current financial statement showing the limits of its established self-insurance retention and proof of the primary and excess umbrella insurance. The Authority shall have thirty (30) days to review the proposed self-insurance plan. If the self- insurance plan is approved by the Authority and becomes effective, the Airline shall not increase the self-insurance retention levels stated in the self-insurance plan approved by the Authority without the approval of the Authority. 12.03.5 The Authority reserves the right to periodically review any and all policies of insurance and to request reasonable adjustments in the limits of coverage required hereunder from time to time throughout the Period of this Agreement, but not more frequently than once every two years. The Authority shall provide the Airline with such request in writing and the Airline shall comply within sixty (60) days from the receipt thereof. ARTICLE 13. AUTHORITY REMEDIES 13.01 Default. The occurrence of any of the following events shall be considered an event of default by the Airline: 13.01.1 The Airline becomes insolvent (as such term is defined under Section 101 of the Federal Bankruptcy Code, 11 U.S.C. 101 et seq., or any successor statute thereto); or fails to pay its debts generally as they mature; or takes the benefit of any present or future Federal or state insolvency statute; or makes a general assignment for the benefit of creditors, or files a voluntary petition in bankruptcy or a petition or answer seeking an arrangement of its indebtedness under the Federal Bankruptcy Code or under any other law or statute of the United States or of any state thereof, or consents to the appointment of a receiver, trustee, custodian, liquidator, or other similar official, of all or substantially all of its property; or an order for relief shall be entered by or against the Airline under any chapter of the Federal Bankruptcy Code. 13.01.2 The Airline is adjudged a debtor or bankrupt by order or decree of a court, or an order is made approving a petition filed by any of the Airline's creditors or by any of its stockholders, seeking its reorganization or the restructuring of its indebtedness under the Federal Bankruptcy Code or under any other law or statute of the United States or any state thereof, and such order or decree shall not be stayed or vacated within sixty (60) days of its issuance. 13.01.3 A petition under any chapter of the Federal Bankruptcy Code or an action under any Federal or state insolvency law or statute shall be filed against the Airline and is not dismissed or stayed within sixty (60) days after the filing thereof. 13.01.4 A receiver, trustee, custodian, liquidator, or other similar official takes possession or control of all or substantially all of the property of the Airline by or pursuant to, or under authority of any legislative act, resolution, or rule, or any order or decree of any court or governmental board, agency, or officer, and such possession or control continues in effect for a period of sixty (60) days. 13.01.5 The Airline becomes a corporation in dissolution. 13.01.6 The transfer, passing, or devolving of any interests or rights of the Airline hereunder, by operation of law or otherwise1 to any other person, firm, corporation, or other entity, by, in connection with, or as a result of any bankruptcy, insolvency, trusteeship, liquidation, or other proceedings or occurrence described in Paragraphs 13.01.1 through 13.01.5. 13.01.7 The discontinuance by the Airline of its Air Transportation Business at the Airports for a period of thirty (30) consecutive days or for a period of sixty (60) days in any Fiscal Year; provided, however, that suspension of operations by the Airline during a strike or work stoppage by its employees at the Airports, or for similar reasons beyond the control of the Airline, shall not be a discontinuance of operations. 13.01.8 The voluntarily discontinued use or abandonment by the Airline for a period of thirty (30) consecutive days of all, or a portion, of its Premises or Equipment at one or both Airports and the failure to remedy this condition within thirty (30) days of notice to remedy same from the Authority. 13.01.9 The failure of the Airline to pay rentals, fees, and charges or any other payment required by this Agreement when due and the expiration of the period, if any, provided for herein after which said payment due becomes delinquent, except, however, in the event of a dispute over a payment, the Airline shall not be in default provided that the Airline has presented, at the time the payment is due, the dispute in detail and in writing, to the General Manager of the Authority. The decision of the General Manager will reinstate or modify the amount due and the due date. The Airline shall pay the amount due as specified by the General Manager within ten (10) days of the receipt of notice from the General Manager. If a dispute remains over that amount, the Airline agrees to pay the amount claimed by the Authority while pursuing its remedies. 13.01.10 The failure of the Airline to maintain the minimum insurance levels required in Articles 11 and 12 of this Agreement. 13.01.11 The failure of the Airline to provide Contract Security required pursuant to Section 8.13. 13.01.12 The conduct of any business, practice, or performance of any act at the Airport which is not specifically authorized herein or by any other agreement between the Authority and the Airline, if said business or act does not cease permanently within thirty (30) days of receipt of the Authority's written notice to cease said business, practice, or act. 13.01.13 The nonperformance by the Airline of any other material covenant, condition, term, or agreement required to be performed by the Airline herein, and the continued failure of the Airline (i) to remedy such nonperformance within a thirty (30) day period after receipt of written notice from the Authority to remedy the same; or (ii) to diligently commence and proceed towards a remedy for such nonperformance which cannot be remedied within such thirty (30) day period in which event the Airline shall have the burden of proving that the nonperformance cannot be remedied within thirty (30) days, that it is proceeding with diligence to remedy same, and that such nonperformance will be remedied within a reasonable period of time. 13.01.14 The issuance of an order or the taking of action by any court or governmental authority having jurisdiction over the Airline's operations which for a period of thirty (30) days substantially limits or prohibits the Airline's operations at the Airports. Provided, however, that before it invokes its remedies for a default under this Paragraph 13.01.14, the Authority will have reasonably determined that the material adverse consequences of a default herein cannot be substantially eliminated by the procedures available to the Authority under Article 17. 13.02 Remedies. 13.02.1 In addition to any remedy provided by law, and except for defaults under Paragraph 13.01.8, if the Airline shall be in default under this Agreement, and if the notice of default to the Airline stated that this Agreement could, as a result thereof, be terminated, the Authority shall have the right, in its sole discretion, to terminate this Agreement. The termination may be effective in not less than ten (10) calendar days from the date of written notice of termination from the Authority unless the Airline has cured the default during this period. 13.02.2 The Authority's remedies for a default under Paragraph 13.01.8 includes the right to reclaim, in its discretion, the Premises that have been abandoned and to delete same from the Airline's Agreement. Such reclamation may be effective in not less than ten (10) calendar days from the date of written notice from the Authority. Nothing herein shall preclude the Authority from terminating this Agreement in its entirety in the event that the Airline's default under Paragraph 13.01.8 relates to all of its Premises at both Airports. Nothing herein shall, in the event of a default under Paragraph 13.01.8, preclude the Authority, as an alternative to reclaiming the Premises or Equipment or terminating this Agreement, from continuing to hold the Airline responsible for the performance of this Agreement for the Period thereof. 13.02.3 Upon the effective date of termination or reclamation under Paragraphs 13.02.1 or 13.02.2, respectively, the Authority may re-enter and take immediate possession of the Premises. Notices of termination or reclamation under Paragraphs 13.02.1 or 13.02.2 shall operate as a notice to quit and any other notice to quit or notice of the Authority's intention to re- enter the Premises is hereby expressly waived. If necessary, the Authority may proceed to recover possession of the Premises under and by virtue of the laws of the Commonwealth of Virginia, or by such other proceedings, including re-entry and possession, as may be applicable. If the Authority elects to terminate this Agreement in whole or in part, everything contained in this Agreement on the part of the Authority to be done and performed shall cease without prejudice to the right of the Authority to recover from the Airline all rentals, fees, charges, and other sums accrued up to the time of termination or recovery of possession by the Authority, whichever is later. Further, the Authority shall use its best efforts to relet the Premises, and, if the full rentals provided for herein plus the costs, expenses, and damages described below shall not be realized by the Authority, the Airline shall be liable for all damages sustained by the Authority, including, without limitation, any deficiency in rentals, fees, and charges, the expenses of placing the Premises in good rentable condition, and reasonable attorneys' fees. The provisions contained in this Section shall be in addition to, and shall not prevent the enforcement of, any claim the Authority may have against the Airline for anticipatory breach of this Agreement. 13.02.4 All rights and remedies of the Authority set forth herein are in addition to all other rights and remedies available to the Authority at law or in equity. All rights and remedies available to the Authority hereunder, at law or in equity, are expressly declared to be cumulative. The exercise by the Authority of any such right or remedy shall not prevent the concurrent or subsequent exercise of any other right or remedy. No delay in the enforcement or exercise of any such right or remedy shall constitute a waiver of any default by the Airline hereunder or of any of the Authority's rights or remedies in connection therewith. The Authority shall not be deemed to have waived any default by the Airline hereunder unless such waiver is set forth in a written instrument signed by the Authority. If the Authority waives in writing any default by the Airline, such waiver shall not be construed as a waiver of any covenant, condition, or term set forth in this Agreement except as to the specific circumstances described in such written waiver. 13.02.5 If the Authority shall institute proceedings against the Airline and a compromise or settlement thereof shall be made, the same shall not constitute a waiver of any subsequent breach of the same or of any other covenant, condition, or term set forth herein, nor of any of the Authority's rights hereunder with regard to any future occurrence of the same or other matter. Neither the payment by the Airline of a lesser amount than the full rentals, fees, and charges due hereunder nor any endorsement or statement on any check or letter accompanying a check for payment of rent or other sums payable hereunder shall be deemed an accord and satisfaction, and the Authority may accept such check or payment without prejudice to the Authority's right to recover the balance of such rent or other sums or to pursue any other remedy available to the Authority. Unless previously agreed to by the Authority in writing, no re-entry by the Authority shall be considered an acceptance of a surrender of this Agreement or Premises. 13.03 To the extent that the Authority's right to terminate this Agreement as a result of an event enumerated in Paragraphs 13.01.1 through 13.01.6 of this Article is determined to be unenforceable under the Federal Bankruptcy Code, as amended from time to time, or under any other statute, then the Airline and any trustee who may be appointed agree (i) to perform promptly every obligation of the Airline under this Agreement until this Agreement is either assumed or rejected under the Federal Bankruptcy Code; (ii) to pay on a current basis all rentals, fees, and charges set forth in this Agreement; (iii) to reject or assume this Agreement within sixty (60) days of a filing of a petition under the Federal Bankruptcy Code; (iv) to cure or provide adequate assurance of a prompt cure of any default of the Airline under this Agreement; and (v) to provide to the Authority such adequate assurance of future performance under this Agreement as may be requested by the Authority, including a tender of Contract Security as set forth in Section 8.13 of this Agreement. 13.04 Special Cancellation Right. In the event that the United States government determines that the Airline has failed to comply with the nondiscrimination covenants set forth in Section 18.04 herein, the Authority shall have the right to cancel this Agreement after such action as the United States government may direct to enforce such covenants has been followed and completed, including exercise or expiration of appeal rights ARTICLE 14. AIRLINE REMEDIES 14.01 Default. The occurrence of the following shall be considered an event of default by the Authority The failure of the Authority to perform any material covenant or term required to be performed by the Authority and the failure continues for thirty (30) days after receipt of written notice from the Airline, or, if by its nature such default cannot reasonably be cured within thirty (30) days, the Authority fails to diligently commence to cure such default within said thirty (30) day period after receipt from the Airline of written notice to remedy the same 14.02 Airline's Remedy. Provided the Airline is not itself in default of this Agreement as set forth in Article 13, the Airline may bring an appropriate action in a court of competent jurisdiction to compel the Authority to perform in accordance with the terms of this Agreement. 14.03 Termination. At any time when no Bonds are Outstanding, and if the Airline is not then in default in the payment of any amount due from it to the Authority hereunder, the Airline may terminate this Agreement by giving the Authority sixty (60) days advance notice upon or after the happening and during the continuance of any one of the following events: (i) The issuance by any court of competent jurisdiction of an injunction in any way preventing or restraining the use of the Airport or any part thereof so as to substantially limit or prohibit the Airline's use of the Airport in the conduct of its Air Transportation Business, and the remaining in force of such injunction, not stayed by way of appeal or otherwise, for a period of at least sixty (60) days; (ii) The enactment of any law, issuance of any order, rule, ordinance, or regulation, or the taking of any action by a Federal, state, or local government body or agency having jurisdiction with respect to the Airport, or the occurrence of any fire, other casualty, act of God or the public enemy, substantially limiting or prohibiting, for a period of at least sixty (60) days, the Airline's use of the Airport in the conduct of its Air Transportation Business; provided, however, that none of the foregoing is instituted or initiated by the Airline or due to any fault of the Airline; (iii) The default by the Authority in the performance of any material covenant or agreement required to be performed by the Authority herein, which default materially and adversely limits or prohibits the Airline's operations at the Airport, and the failure by the Authority to remedy such default after written notice thereof has been delivered to the Authority, unless (a) the Authority takes prompt action to remedy such default within a period of thirty (30) days after receipt from the Airline of such notice, or (b) in the case of any such failure which cannot with due diligence be cured within such thirty (30) day period, the Authority takes corrective action within the thirty (30) day period and diligently pursues such action until the failure is cured. (iv) The substantial limiting or restricting of the Authority's operation of the Airport by action of any Federal, state, local government body or agency having jurisdiction with respect thereto, and the continuance thereof for a period of not less than sixty (60) days, provided such restriction materially and adversely affects the Airline's operations at the Airport. ARTICLE 15. SURRENDER OF PREMISES; HOLDING OVER 15.01 Surrender and Delivery. Immediately upon termination or the expiration of this Agreement, or upon deletion of any portion of the Premises (including TAP) and Equipment leased hereunder in accordance with Article 5 or 17, the Airline shall peaceably surrender and deliver to the Authority the Premises and Equipment that are the subject of said expiration or termination. Premises and Equipment shall be surrendered in good condition, with the exception of ordinary wear from use of the Premises and Equipment for the purpose for which they were leased. After surrender, the Airline agrees to pay to the Authority the costs, if any, incurred by the Authority to bring the Premises and Equipment up to such condition. 15.02 Removal of Property. 15.02.1 Except as provided in Paragraph 15.02.2, nothing herein shall be construed to preclude the Airline from removing from the Airports or otherwise disposing of its personal property, including aircraft, tools, equipment, and trade fixtures, title to which is to remain with the Airline. All Authority property damaged by or as a result of the removal of Airline property shall be promptly restored by the Airline to the condition existing before such damage, at the Airline's sole cost and expense. Such aircraft, tools, equipment, trade fixtures, and other personal property shall be removed upon the expiration of this Agreement or from any portion of the Premises upon the deletion from this Agreement of that portion from the Premises leased hereunder. 15.02.2 Any removal of property by the Airline pursuant to this Section 15.02 shall be subject to any valid lien which the Authority may have thereon and such property shall not be removed from the Airport without the written consent of the Authority. 15.02.3 At the expiration or termination of this Agreement, any personal property of the Airline not removed in accordance with Paragraph 15.02.1 above, at the option of the Authority, may be removed and placed in storage by the Authority at the sole cost of the Airline. If such property is not removed from storage by the Airline within one month after placement therein, the Authority may elect, after notice to the Airline, to take ownership of the property or dispose of the property by either public or private sale and retain the proceeds. Any costs of removal and disposition not covered by such proceeds shall be borne by the Airline. 15.03 Holding Over. In the event the Airline holds over, refuses, or fails to give up the possession of the Premises and Equipment at the expiration or termination of this Agreement, or the relevant portion of Premises and Equipment in the event of expiration or termination of the lease for said portion, without written consent of the Authority, the Airline shall have only the status of a tenant at sufferance and no periodic tenancy will be deemed to have been created. The Airline shall pay reasonable rentals, rates, and charges as then prescribed by the Authority and such rentals, rates, and charges may be different from those prescribed during the Period of the Agreement. Rent shall be paid on a pro rata basis for the period of time that the Airline is in such a hold over status. Further, in the event that the Airline holds over, and if the Authority shall desire to regain possession of the Premises, then the Authority may re-enter and take possession of the Premises. Furthermore, if the Authority so elects, it may accept rent and concurrently commence legal proceedings to regain possession of the Premises. ARTICLE 16. TRANSFER OF PREMISES BY ASSIGNMENT, SUBLETTING, ETC. HANDLING AGREEMENTS 16.01 General. The Airline shall not assign, transfer, convey, sell, mortgage, pledge, or encumber (hereinafter collectively referred to in Article 16 as "assignment") or sublet its Premises or Equipment, without the prior written approval of the Authority. The Airline shall not allow the use of its Premises or Equipment through a handling or services agreement or similar arrangement (hereinafter collectively referred to in Article 16 as "handling agreements") by any other Air Transportation Company without the prior written approval of the Authority. If the Airline fails to obtain prior written approval of any such assignment, sublease, or handling agreement, the Authority, in addition to the rights and remedies set forth in Article 13, shall have the right to refuse to recognize the agreement and the assignee, sublessee or "handled" Air Transportation Company shall acquire no interest in this Agreement or any rights to use Premises or Equipment. 16.02 Authority Approval of Assignments. It shall not be unreasonable for the Authority to disapprove or condition an assignment of the Airline's Premises or Equipment under any or all of the following circumstances, among others: 16.02.1 If the Airline has failed to accommodate a Requesting Airline on reasonable terms prescribed by the Authority in accordance with Article 17. 16.02.2 If said assignment would result in the transfer of fifty percent (50%) or more of any of the following the Airline's linear feet of ticket counter space; square feet of holdroom space; or number of gate positions. 16.02.3 If the assignee is not, and is not willing to become, a Signatory Airline. 16.02.4 If a Signatory Airline, including a Signatory Airline which is not leasing space directly from the Authority because of the unavailability of such space, is, in the determination of the Authority, in need of the Premises and/or Equipment proposed to be assigned; provided, however, that such signatory Airline is willing to take such Premises and Equipment on substantially the same terms and conditions relating to the use of such Premises and Equipment to be assigned as proposed in the assignment. 16.02.5 If the Authority determines that there is adequate space for lease by the proposed assignee directly from the Authority. 16.02.6 If the Authority determines that the proposed assignee is not substantially as creditworthy as the Airline. 16.02.7 Notwithstanding the foregoing, this section shall not be interpreted to preclude the assignment of this Agreement, and the Airline's rights and obligations hereunder, to a parent, subsidiary, or merged company if such parent, subsidiary, or merged company conducts an Air Transportation Business at the Airport at which the Airline is a Signatory Airline and assumes all rights and obligations hereunder. Written notice of such assumption shall be provided by the parent, subsidiary, or merged company thirty (30) days prior to the effective day of such assignment. 16.03 Authority Approval of Subleases. It shall not be unreasonable for the Authority to disapprove or condition a sublease of the Airline's Premises or Equipment under any or all of the following circumstances, among others: 16.03.1 If the Airline has failed to accommodate a Requesting Airline on reasonable terms prescribed by the Authority in accordance with Article 17. 16.03.2 If said sublease would result in the sublease (i) for a period greater than fifty percent (50%) of the remaining Period of the Agreement, and (ii) is for greater than fifty percent (50%) of any of the following Premises the Airline's linear feet of ticket counter space; square feet of holdroom space; or number of gate positions. 16.03.3 If the sublessee is an Air Transportation Company who is not, and is not willing to become, a Signatory Airline. 16.03.4 If a Signatory Airline, including a Signatory Airline which is not leasing space directly from the Authority because of the unavailability of such space, is, in the determination of the Authority, in need of the Premises and/or Equipment proposed to be subleased; provided, however, that such Signatory Airline is willing to take such Premises or Equipment on substantially the same terms and conditions as proposed in the sublease and is willing to provide the Airline with a reasonable security deposit, not to exceed three (3) months' rentals. 16.03.5 If the Authority determines that there is adequate space for lease directly from the Authority by the proposed sublessee or if the sublease does not contain a provision which permits it to be terminated upon notice from the Authority to the parties thereto of the availability of Premises in accordance with Section 1.04. 16.04 Authority Approval of Handling Agreements. It shall not be unreasonable for the Authority to disapprove or condition a handling agreement if the Airline has failed to accommodate a Requesting Airline on reasonable terms prescribed by the Authority in accordance with Article 17. 16.05 Reasons for Disapproval. The circumstances under which the Authority may determine to disapprove or condition assignments, subleases, and handling agreements set forth in Sections 16.02, 16.03, and 16.04 are not intended to be a comprehensive list of all those which the Authority may impose under Section 16.01. 16.06 Method of Obtaining Approval. The Airline, when requesting an approval of an assignment, sublease, or handling agreement under Section 16.01, shall include with its request a copy of the proposed agreement, if prepared, or a detailed summary of the material terms and conditions to be contained in such agreement. Any proposed agreement or detailed summary thereof shall provide the following information (i) the Premises and/or Equipment to be assigned, sublet, or used under a handling agreement; (ii) the terms; (iii) if a sublease, the rentals and fees to be charged; and (iv) all material terms and conditions of the assignment, sublease, or handling agreement the Authority may reasonably require. If approved, the Airline shall submit a fully executed copy of such agreement to the Authority within thirty (30) days prior to the commencement of the assignment or sublease or within fifteen (15) days after the commencement of the handling agreement. 16.07 Administrative Charge. In the event the Airline is authorized by the Authority to sublease any portion of its Premises or Equipment, the Airline may charge such sublessee, in addition to a reasonable charge for any services and Airline owned property provided by the Airline or actual costs other than rental costs incurred by the Airline, reasonable rentals not to exceed one hundred fifteen percent (115%) of the Airlines' rentals for such portion of the Premises and Equipment. 16.08 Airline to Remain Liable. The Airline shall remain fully and primarily liable during the Period of this Agreement for the payment of all of the rental due and payable to the Authority for the Premises and Equipment that are subject to an assignment, sublease, or handling agreement under Section 16.01, and fully responsible for the performance of all the other obligations hereunder, unless otherwise agreed to by the Authority; provided, however, this Section 16.08 shall not apply to Premises and Equipment with respect to which an assignment has been made at the Authority's request pursuant to Paragraph 16.02.4 hereof. 16.09 Authority Determination of Type of Agreement. The Authority shall have the right to examine the terms of any agreement or arrangement submitted to it for approval pursuant to this Article 16, and determine whether such agreement or arrangement is most appropriately characterized as an assignment, sublease, or handling agreement, regardless of the Airline's characterization of such agreement or arrangement. ARTICLE 17. AVAILABILITY OF ADEQUATE FACILITIES 17.01 General. The Authority and the Airline agree that facilities at the Airports are limited and the Airline shall cooperate fully with the Authority's exercise of its obligation to prudently operate and manage the Airports so as to provide adequate facilities for all Air Transportation Companies, including the Airline1 operating or desiring to operate at the Airports. 17.02 Periodic Reallocation of Premises. It is recognized that an allocation of Premises at National occurred in 1989 and is reflected in Exhibits N-B and D-B. It is recognized that an allocation of Premises will occur at Dulles in conjunction with the westerly and easterly expansions of the Main Terminal and said allocation will be consistent with Section 6.04. In addition to any other rights of the Authority, the Authority may, effective the date which is nine (9) months prior to the date of Substantial Completion of the new North Terminal at National and on every third anniversary of the date of Substantial Completion thereafter, reallocate the Airline's Premises and Equipment at National Airport among the Signatory Airlines. In addition to any other rights of the Authority, the Authority may, effective on the date which is the third anniversary of the date of Substantial Completion of the westerly expansion of the Main Terminal at Dulles and on every third anniversary of that date thereafter, reallocate the Airline's Premises and Equipment at Dulles Airport among the Signatory Airlines. Such reallocations may result in the reduction of the Airline's Premises and Equipment and/or cause the Airline to vacate Premises and relocate to other Premises. The reallocation of any Premises shall be accomplished in accordance with a utilization study conducted by the Authority which shall take into account the following factors, among others: (i) Each Signatory Airline's historical, current and reasonably projected frequency of operations; (ii) Each Signatory Airline's number of Enplaning and Deplaning Passengers; (iii) Each Signatory Airline's number of gates; (iv) Each Signatory Airline's linear feet of ticket counter space, square feet of holdroom space and square feet of other Premises; (v) The need to provide Premises and Equipment to a Signatory Airline which is without adequate Premises and Equipment leased directly from the Authority due to the unavailability of such space; (vi) The practicality of the Authority constructing additional Premises within a reasonable period of time; and (vii) The need for the Authority to manage aircraft and passenger activity at the Airport in order to correct an imbalanced use of Airport facilities, including Aircraft Parking Positions, or to minimize or ameliorate congestion in the Terminal or at the curbside. 17.02.1 In making such reallocations, the Authority shall give the Airline, along with other Signatory Airlines at the affected Airport, not less than thirty (30) days written notice of the proposed space reallocations together with the Authority's reasons for the reallocations. The Airline shall during the thirty (30) day period be entitled to respond to the proposed reallocations in writing. A final decision of the Authority shall be in writing from the General Manager and contain the basis therefor along with the effective date of a reallocation, if any. 17.02.2 In implementing such reallocations, the Authority shall attempt to minimize disruptions to the Airline's operations and to preserve the operational integrity of the Airline's Premises during and after such reallocation. 17.02.3 If, as a result of a reallocation under this Section 17.02, the Airline is required to relocate all or a portion of its operations, or to consolidate its operations in its remaining Premises, the Authority shall determine the reasonable cost of such relocation or consolidation, including the unamortized cost on the basis of generally accepted accounting principles of reallocated Airline Operating Facilities and fixed improvements vacated by the Airline, and said costs shall be borne by the Signatory Airline gaining the use of the reallocated Premises or Equipment, and shall be paid to the Airline. 17.02.4 The Authority shall revise the Exhibits hereto, as appropriate, to reflect the resulting modifications of the Agreement, and such amended Exhibits shall be substituted herein. 17.03 Voluntary Accommodation of a Requesting Airline. 17.03.1 The need exists to maximize the use of facilities that are available on a long term basis to the signatory Airlines and to facilitate the entry of new Scheduled Air Carriers and the expansion of service by other Scheduled Air Carriers operating at the Airports (hereinafter collectively referred to as "Requesting Airline(s)"). The Authority hereby expresses a preference to have, to the extent possible, a Requesting Airline's need to use the Airport(s) accommodated by the Signatory Airlines on a voluntary basis. The Airline's voluntary accommodation of a Requesting Airline hereunder shall be subject to the prior execution of a handling agreement or written sublease between the Airline and such Requesting Airline setting forth mutually agreed upon terms, conditions, rates and charges, which handling agreement or sublease shall also require the written approval of the Authority prior to the effectiveness thereof in accordance with Article 16. Any such accommodation agreement made by the Airline and the Requesting Airline may define the priority rights of the Airline. 17.04 Accommodation on Exclusive and Joint Use Premises. 17.04.1 In the event the Authority receives a written request from a Requesting Airline for a type of space leased on an exclusive or joint use basis to others, and the Requesting Airline demonstrates to the satisfaction of the Authority that it has contacted all Signatory Airlines at a level above the local station manager and has exhausted all reasonable efforts to find reasonable accommodations for its proposed operations on the Airport, the Authority shall serve written notice to all Signatory Airlines of the Authority's intention to make a determination, in not less than fifteen (15) calendar days, as to how the Requesting Airline will be accommodated. 17.04.2 The Authority will be guided by all pertinent factors, including Airline's present use and the use planned by the Airline for such Premises in the one hundred eighty (180) days immediately after the request, the present and planned requirements for Air Transportation Companies that the Airline is then accommodating or handling, the compatibility of such Requesting Airline's proposed operations and work force with the Airline's own operations and work force and those of other Air Transportation Companies already using such facilities, and the security of the Airline's and the Requesting Airline's operations. 17.04.3 The Authority may request that planned uses and requirements be documented and submitted in writing to the Authority, and if the Airline requests, the Authority shall treat such planned uses and requirements as confidential, proprietary information. 17.04.4 If the Authority determines that the Requesting Airline can be accommodated on the Airline's Exclusive or Joint Use Premises, the Authority may (i) authorize in writing the Requesting Airline to use the Premises leased to the Airline; (ii) notify the Airline in writing of such authorization and the effective date thereof; and (iii) provide to the Airline and to such Requesting Airline a written statement specifying the required terms and conditions, if any, including whether the Requesting Airline may handle its aircraft and passengers with its own employees or agents, except that the Authority shall not prescribe the rates and charges to be imposed by the Airline upon the Requesting Airline for any services provided by the Airline to the Requesting Airline, other than as prescribed in Article 16. 17.04.5 If the Airline is directed to accommodate a Requesting Airline in accordance with Section 17.04 and Section 17.06, the Airline shall make available to the Requesting Airline for the Requesting Airline's use, the Airline's Exclusive or Joint Use Premises or such portion thereof as shall be determined by the Authority. 17.05 Accommodation on Preferential Use Premises. 17.05.1 In the event the Authority receives a request from a Requesting Airline for a type of space leased on a preferential basis to others, the Authority shall make a determination as to how the Requesting Airline will be accommodated. Promptly thereafter, the Authority shall notify the Airline of any planned accommodation on the Airline's Preferential Use Premises; provided, however, the Authority has determined that the Requesting Airline's schedule is compatible with the Airline's priority use as described in Paragraph 17.05.2 and would not require the Airline to reschedule an existing arrival or departure. The Airline shall, consistent with its right of priority use, as described in Paragraph 17.05.2, accommodate such Requesting Airline as directed by the Authority by providing access to and use of its Preferential Use Premises. 17.05.2 If the Airline is directed to accommodate a Requesting Airline under Paragraph 17.05.1, the Airline shall have the priority use of such Premises at all times except for each period commencing fifteen (15) minutes before the Requesting Airline's next scheduled arrival at a gate and continuing until the earlier of the Requesting Airline's scheduled departure from the gate or forty-five (45) minutes (one hundred twenty (120) minutes for a wide body aircraft) before the next scheduled use of the gate by the Airline assuming there is no other gate available to the Airline for such next scheduled use. The Airline may make a change in its own scheduled use of said facilities by giving the Requesting Airline who is being accommodated at least thirty (30) days notice of any schedule change that would require the Requesting Airline to change its schedule or otherwise discontinue use of said facilities. In the event of any conflicts due to schedule delays of either the Airline or the Requesting Airline, such conflicts shall be resolved in the manner least likely to inconvenience the passengers of both airlines. Such conflicts shall be resolved by the Airline and the Requesting Airline whenever possible. In the absence of such resolution, the Authority shall resolve such conflicts. 17.05.3 Accommodation on Preferential Use Premises shall not be subject to the procedures of Section 17.04, but shall be as directed by the Authority for the operations of aircraft by an Air Transportation Company; provided, however, that the Authority shall not require an accommodation under this Section 17.05 unless there is not a reasonable means of accommodating the Air Transportation Company on Premises and Equipment obtained directly from the Authority, and, if the Requesting Airline is a Signatory Airline, there is not a reasonable means as determined by the Authority, of accommodating the aircraft operations on that Signatory Airline's Premises and Equipment. 17.05.4 For purposes of Paragraph 17.05.1, a direction by the Authority shall be sufficient if given by the manager of the Airport to the Airline's manager of its station for the Airport. 17.06 Use of Equipment. In connection with an accommodation pursuant to Section 17.04 or 17.05, the Authority may also authorize the Requesting Airline to use Equipment or airline- owned equipment; provided, however, that whenever the Requesting Airline is authorized to use airline-owned equipment, the following conditions shall apply (i) such equipment must be essential to the accommodation of the Requesting Airline (e.g., loading bridges and baggage claim and makeup equipment), and (ii) when reasonably required, the Airline may require the Requesting Airline to use the Airline's employees to operate such equipment. 17.07 Indemnification. During the period of accommodation by a Requesting Airline pursuant to Sections 17.04 through 17.06, the Airline shall be relieved of its obligation under this Agreement to indemnify and save harmless the Authority, its officers, directors, employees, or agents with regard to any claim for property damage or personal injury arising out of the accommodation of said Requesting Airline unless such damage or injury is caused by the negligence or willful misconduct of the Airline, its officers, directors, employees, or agents. The Authority shall require the Requesting Airline to agree in writing to indemnify the Authority and the Airline in the manner and to the extent required of the Airline, pursuant to Article 12 hereof. 17.08 Payment by Requesting Airline. Payment by the Requesting Airline to the Airline for accommodation on the Airline's Premises or Equipment or Airline-owned property and for services shall be reasonable and for the Premises or Equipment or Airline-owned property shall not exceed one hundred fifteen percent (115%) of the Airline's cost on a pro-rata basis. The Airline may require a reasonable security deposit from the Requesting Airline, not to exceed three (3) months' payments. In the event of a payment default by the Requesting Airline, the Airline may institute termination procedures in the following manner (i) the Airline shall certify such payment default to the Authority; (ii) the Authority shall have fifteen (15) days in which to pursue appropriate remedies against the Requesting Airline; and (iii) if, after such fifteen (15) day period, the Requesting Airline remains in default, the Airline may terminate the Requesting Airline's use of such Premises, Equipment and airline-owned equipment upon fifteen (15) days' notice. ARTICLE 18. FEDERAL REQUIREMENTS 18.01 Relationship to Federal Lease. This Agreement shall be and remain subordinate to the provisions of the Federal Lease dated March 2, 1987, between the United States Department of Transportation and the Authority, providing for the Authority's lease of the Airports effective June 7, 1987. The Authority agrees to provide the Airline written advance notice of any material amendments to the Federal Lease. At any time after the execution of this Agreement, the United States Department of Transportation, or its successor, shall have the right to declare this Agreement to be superior to the Federal Lease. 18.02 Other Government Agreements. This Agreement shall be and remain subordinate to the provisions of any existing or future agreements between the Authority and the United States government or other governmental authority, relative to the operation or maintenance of the Airports, the execution of which has been or will be required as a condition precedent to the granting of Federal or other governmental funds for the development of the Airport, to the extent that the provisions of any such existing or future agreements are generally required by the United States or other governmental authority of other civil airports receiving such funds. The Authority agrees to use its best efforts to notify the Airline of any provision of which the Authority becomes aware which would materially and adversely modify the material terms of this Agreement. 18.03 Federal Government's Emergency Clause. All provisions of this Agreement shall be subordinate to the rights of the United States of America to operate the Airports or any portion thereof during time of war or declared national emergency in accordance with established lawful procedures. Such rights shall supersede any provision of this Agreement that is inconsistent with the operation of the Airports by the United States of America during a time of war or national emergency. 18.04 Nondiscrimination. 18.04.1 The Airline for itself, its personal representatives, successors in interest, and assigns, as a part of the consideration hereof, does hereby agree as a covenant running with the land that (i) no person on the grounds of race, color or national origin shall be excluded from participation in, denied the benefits of, or be otherwise subjected to discrimination in the use of Premises; (ii) in the construction of any improvements on, over, or under Premises and the furnishing of services thereon, no person on the grounds of race, color or national origin shall be excluded from participation in, denied the benefits of, or be otherwise subjected to discrimination; and (iii) the Airline shall use the Premises in compliance with all other requirements imposed by or pursuant to the Airport and Airway Improvement Act of 1982, as amended or superseded, and any regulations issued thereunder, as well as in compliance with Title VI of the Civil Rights Act of 1964 and 49 CFR, Subtitle A, Part 21, Nondiscrimination in Federally Assisted Programs of the United States Department of Transportation, as said Statute and regulations may be amended. 18.04.2 The Airline acknowledges that the provisions of 49 CFR Part 23, "Participation by Minority Business Enterprise in Department of Transportation Programs," as said regulations may be amended, and such other similar regulations that may be enacted governing Disadvantaged Business Enterprises, may be applicable to the activities of the Airline under the terms of this Agreement, unless exempted by said regulations, and hereby agrees to comply with the applicable regulations. These requirements may include, but not be limited to, compliance with Disadvantaged Business Enterprise or Minority Business Enterprise, as such terms are defined in 49 USC 2204, 49 CFR 23.5, or such other statutes or regulations as may be enacted governing minority or disadvantaged business enterprises, participation goals, the keeping of certain records of good faith compliance efforts, which would be subject to review by the various agencies, the submission of various reports and, if so directed, the contracting of specified percentages of goods and services contracts to Minority and Disadvantaged Business Enterprises. 18.05 Airfield and Sterile Area Security. The Airline expressly acknowledges its responsibility to provide security for the sterile area in accordance with 14 CFR Part 107, "Airport Security," and 14 CFR Part 108, "Airplane Operator Security," as such may be amended from time to time, and with all rules and regulations of the Authority concerning security procedures, including each Airport's approved security program. 18.06 Airport Certification. The Airline shall not operate at the Airports in a manner that prevents or impairs the Authority's ability to meet and maintain compliance with 14 CFR Part 139, "Certification and Operations Land Airports Serving Certain Air Carriers," and other requirements for obtaining, and maintaining, an Airport Operating Certificate from the FAA. ARTICLE 19. GENERAL PROVISIONS 19.01 Rights Reserved to the Authority. All rights not specifically granted to the Airline by this Agreement are reserved to the Authority. 19.02 Actions By the Authority and the Signatory Airlines. Whenever in this Agreement the doing of any act or the exercise of any right by the Airline is conditioned upon receipt of approval, permission, agreement or authorization, the Authority shall promptly render its decision and shall neither unreasonably withhold nor unreasonably condition its approval of a request by the Airline. Whenever in this Agreement any approval is required from the Airline or from a Majority-in-Interest, such decision shall be promptly rendered and shall not be unreasonably withheld or conditioned. 19.03 Majority-in-Interest Approval Procedures. The Authority shall initiate the Majority-in-Interest approval process by delivering the request for approval to the Signatory Airlines at the appropriate Airport for the appropriate Cost Center. The request will be deemed to have been approved unless the Authority receives, within thirty (30) days, written notice of disapproval from the Signatory Airlines representing a Majority-in-Interest at such Airport for such Cost Center. 19.04 Authority Not Liable. Except as specifically provided for in this Agreement, the Authority shall not be under any duty or obligation to the Airline to repair or maintain the Premises, or any portion thereof, or any facilities or equipment constructed thereon. The Authority shall not be responsible or liable to the Airline for any claims for compensation for any losses, damages, or injury, including lost profits, sustained by the Airline resulting from failure of any water supply, heat, air conditioning, electrical power, or sewer or drainage facility, or caused by the natural physical conditions on the Airports, whether on the surface or underground, including stability, moving, shifting, settlement of ground, or displacement of materials by fire, water, windstorm, tornado, act of God, or state of war, civilian commotion or riot, or any other cause or peril beyond the control of the Authority, except to the extent covered by the Authority's insurance. 19.05 Laws, Regulations, and Compliance. 19.05.1 Laws and Regulations. The Airline and the Authority shall each comply with all applicable Federal, state, and local laws, codes, regulations, including regulations of the Authority, ordinances, rules, and orders now or hereafter in force; provided, however, that the Airline or the Authority may, without being considered in breach hereof, contest any of the foregoing as long as such contest is diligently commenced and prosecuted by the Airline or the Authority, as the case may be. 19.05.2 Safety and Fire Regulations The Airline shall conduct its operations and activities under this Agreement in compliance with all safety regulations and directives of the Authority and applicable Federal, state, and local laws. The Airline shall procure and maintain such fire prevention and extinguishing devices as required by the Authority and shall at all times be familiar with and comply with the fire regulations and orders of the Authority. 19.05.3 Security. The Airline understands that the police security protection provided by the Authority is finite and limited to that generally provided to any other airline or business on the Airports and expressly acknowledges that any special security measures deemed necessary or desirable for additional protection of the Premises, equipment, improvements, and the Airline's personal property, and that of its employees and invitees shall be the sole responsibility of the Airline and shall involve no cost to the Authority. 19.05.4 Compliance By Other Tenants. The Authority shall, whenever possible, make reasonable efforts to obtain uniform compliance with the Authority's rules and regulations; however, the Authority shall not be liable to the Airline for any violation or non-observance of such rules and regulations by any user, tenant, concessionaire, other Air Transportation Company, invitee, licensee, or trespasser at the Airports nor shall such violation or non-observance by a user, tenant, concessionaire, other Air Transportation Company, invitee, licensee, or trespasser at the Airports, constitute a waiver of the Airline's obligation to comply with Authority rules and regulations. 19.06 Inspection. The Airline shall allow the Authority's authorized representatives entry to the Premises for the purpose of examining and inspecting said Premises, for purposes necessary, incidental to, or connected with the performance of the Authority's rights and obligations under this Agreement or in the exercise of its governmental functions. Except in the case of an emergency, the Authority shall conduct such inspections during reasonable business hours, and in the presence of the Airline's representative. 19.07 Relationship of the Parties. The Airline is and shall be deemed to be an independent contractor and operator responsible to all parties for its respective acts and omissions, and the Authority shall in no way be responsible therefor. Nothing in this Agreement shall be construed as making the Airline an agent or representative of the Authority for any purpose whatsoever. 19.08 Covenant Not to Grant More Favorable Terms. The Authority shall accord all Signatory Airlines substantially equal treatment and shall not hereafter, during the Period of this Agreement, offer to other Scheduled Air Carriers more favorable rates or terms and conditions at the Airports than those provided in this Agreement for comparable rights and privileges, unless the more favorable rates and conditions are offered to the Airline at the same time; provided, however, nothing herein shall be construed to limit the Authority's rights to distinguish or discriminate among different classes of Air Transportation Companies, or to charge differential rental rates; provided, further, the Airline acknowledges the Surviving Agreements in Exhibits N-K and D-K, that these Surviving Agreements will be accorded priority in the event of a conflict between the terms of a Surviving Agreement and this Agreement, and the Airline agrees that more favorable treatment of one or more Signatory Airlines may result from the implementation of a Surviving Agreement and said treatment shall not be a violation of this covenant specifically or this Agreement generally. 19.09 Quiet Enjoyment. The Authority agrees that, upon payment of the rentals, fees and charges and performance of the covenants and agreements on the part of the Airline to be performed hereunder, the Airline shall peaceably have and, in accordance with the terms hereof, enjoy the Premises and all rights, licenses, services, and privileges of the Airports and their appurtenances granted herein. 19.10 No Individual Liability. No member, officer, agent, director, or employee of the Authority or the Airline shall be charged personally, or held contractually liable by or to the other party, under the terms or provisions of this Agreement, or because of any breach thereof, or because of the execution or attempted execution of this Agreement. 19.11 Waiver of Performance. The failure of the Authority or the Airline, in any one or more instances, to invoke a provision, term, covenant, reservation, condition, or stipulation of this Agreement, or to enforce or take action to enforce, or to demand performance by the other party hereto, or to insist upon a strict performance by the other of any of the provisions, terms, covenants, reservations, conditions or stipulations contained in this Agreement shall not be considered a waiver or relinquishment of the rights to invoke, enforce, demand, or insist thereon, but the same shall continue and remain in full force and effect, and no waiver by either party of any provision, term, covenant, reservation, condition, or stipulation hereof shall be deemed to have been made in any instance unless expressed in writing. In the event any agreement contained in this Agreement is breached by either party and thereafter waived by the other party, such waiver shall be limited to the particular breach so waived and shall not be deemed to be a waiver of any other breach hereunder. 19.12 Force Majeure. Except as herein provided, neither the Authority nor the Airline shall be deemed to be in default hereunder if either party is prevented from performing any of the obligations, other than the payment of rentals, fees and charges hereunder, by reason of strikes, boycotts, labor disputes, embargoes, shortages of energy or materials, acts of God, acts of the public enemy, riots, rebellion, or sabotage. 19.13 Severability. If any article, section, provision, term, or condition of this Agreement is held to be invalid by a court of competent jurisdiction, the remainder of this Agreement, including the remaining rights and obligations of the Authority and the Airline, shall not be affected thereby. 19.14 Subordination to Indenture. 19.14.1 This Agreement and all rights granted to the Airline hereunder are expressly subordinated and subject to the lien and provisions of the pledges, transfer, hypothecation or assignment made by the Authority in any prior Indenture, or Indenture hereafter executed by the Authority, to issue Bonds. The Authority expressly reserves the right to enter into such Indentures and to make such pledges and grant such liens and enter into such covenants as it may deem necessary or desirable to secure and provide for the payment of Bonds, including the creation of reserves therefor; provided, however, that no such pledges, liens, covenants, or reserves shall have a material adverse affect on the Airline. 19.14.2 The Airline understands that the Authority is and will be the issuer of Bonds, the interest on which, with the exception of taxable Bonds, is intended to be excludable from gross income from the holders of such Bonds for Federal income tax purposes under the Internal Revenue Code of 1986. The Airline agrees that it will not act, or fail to act (and will immediately cease and desist from any action, or failure to act) with respect to the use of the Premises and Equipment leased to the Airline under this Agreement, if such act or failure to act may cause the Authority to be in noncompliance with the provisions of the Internal Revenue Code of 1986 as they may be amended, supplemented, or replaced, or the regulations or rulings issued thereunder, nor will the Airline take, or persist in, any action or omission which may cause the interest on the tax-exempt Bonds not to be excludable from the gross income of the holders thereof for Federal income tax purposes. 19.15 Prohibition Against Exclusive Rights. It is hereby specifically understood and agreed that nothing herein contained shall be construed to grant or authorize the granting of an exclusive right to provide aeronautical services to the public as prohibited by Section 308(a) of the Federal Aviation Act of 1958, as amended, and the Authority reserves the right to grant to others the privileges and right of conducting any or all activities of an aeronautical nature. 19.16 Airline Mergers and Consolidations. If the Airline consolidates with or merges into another corporation or permits one or more other corporations to consolidate with or merge into it, or transfers or conveys all or substantially all of its property, assets and licenses to another corporation, the corporation resulting from or surviving such merger (if other than the Airline) or consolidation or the corporation to which such transfer or conveyance is made shall (i) expressly assume in writing and agree to perform all of the Airline's obligations hereunder, (ii) be qualified to do business in the Commonwealth of Virginia, and (iii) if such corporation shall not be organized and existing under the laws of the United States of America or any state or territory thereof or the District of Columbia, furnish to the Authority an irrevocable consent to service of process in, and to the jurisdiction of the courts of, the Commonwealth of Virginia with respect to any action or suit, in law or at equity, brought by the Authority to enforce the Agreement. If the Airline is the surviving corporation in such a merger, the express assumption referred to in the preceding sentence shall not be required. 19.17 No Third Party Beneficiaries. This Agreement is for the benefit of the parties hereto only and is not intended to and shall not create any rights in or confer any benefits upon any person or entity (including any other Signatory Airline) other than the parties hereto. 19.18 Distribution of Funds Upon Termination.

The Authority will notify the Airline of any change in the estimated Substantial Completion Date and the Airline's obligations will remain as agreed to herein with the changed estimated Substantial Completion Date. Failure by the Airline to complete the fitout and furnishing of its exclusively leased Premises shall not delay the Substantial Completion Date for purposes of paragraph 6, below. 5. Substantial Completion Date. On the Substantial Completion Date of the Project, the date of which, unless changed by mutual agreement, shall not be sooner than one hundred and twenty (120) days after the notice given in paragraph 3.b. above, the following shall occur: a. The lease of the Premises in the Regional Concourse and associated Aircraft Parking Positions offered to the Airline shall become effective. Exhibit D-B-1 and D-B-1A shall be deemed amended to add the Airline's Premises and associated Aircraft Parking Positions under the Agreement and all of the provisions, rights, privileges, obligations including rental charges and other fees, terms and conditions of the Agreement as amended shall apply. b. Provided that the Airline has otherwise satisfied all of its requirements for the Authority to issue a certificate of public occupancy, the Airline may occupy its Premises in the Regional Concourse and associated Aircraft Parking Positions for purposes of conducting its Air Transportation Business. The Airline's failure to satisfy all of its requirements for the Authority to issue a certificate of public occupancy shall not delay the effective date of the lease of Premises in the Regional Concourse and associated Aircraft Parking Positions. 6. Rates and Charges. a. For purposes of determining rates and charges under Section 8.03 of the Agreement, the Regional Concourse will be a separate cost Sub-Center ("Regional Concourse Sub- Center"). Other than those costs paid for with PFC revenue, all costs to design, finance, construct, operate and maintain the Regional Concourse, as described under paragraph 1.a. above, and those additional costs allocated to the Regional Concourse under the methodology of Article 8 of the Agreement will be allocated to the Regional Concourse Sub-Center for purposes of determining rates and charges. b. Except as provided in paragraph 8 hereinafter, all other costs to design, finance, construct, and maintain the aircraft movement and parking areas serving the Regional Concourse, as described under paragraph 1.b. above, including the additional costs allocated under the methodology of Article 8 of the Agreement, will be included in the Airfield Cost Center for Washington Dulles International Airport. There will be Aircraft Parking Position Charges as provided for in Section 8.04. of the Agreement assessed to the Airline for the use of the aircraft parking areas serving the Regional Concourse. The Aircraft Parking Position Charges will be established as equivalent to 12 narrow-body air carrier Aircraft Parking Positions for the entire Regional Concourse. That is, three regional/commuter aircraft parking positions will be equivalent to one narrow-body air carrier aircraft parking position for the purpose of assessing the Aircraft Parking Position Charges associated with the Regional Concourse. c. See Attachment B for the estimate of rates and charges of the Regional Concourse with Bonds and PFC's and the estimated Aircraft Parking Position Charges. The amortization period for the Bond financing shall be the life of the Bonds. 7. Bond Financing, Airline Interim Financing, and Passenger Facility Charges (PFC's). The Authority agrees to submit an application to the Federal Aviation Administration (FAA) to impose a PFC and use a portion of the PFC revenue collected, subject to FAA approval, to finance the cost of the construction of those parts of the Regional Concourse eligible for PFC financing. The Airline understands that the application to impose and use PFC revenue may not be approved by the FAA. The Parties agree that, prior to the approval of the application to use PFC revenue, or if the PFC application is not approved, the Parties will pursue either of the following two financing options, as they may mutually decide, to complete the Regional Concourse: a. The Authority may proceed with the usual and customary planning, design, and construction of the Project and pay for such work with the proceeds of Bonds. The Authority agrees that, upon the approval by the FAA to use PFC revenue for the Regional Concourse, the Authority will take reasonable and prudent measures to cause the repayment of the Bonds for those parts of the Regional Concourse eligible for PFC funding up to a limit of the PFC revenue allocated to the Regional Concourse and approved by the FAA. The Airline also understands that to the extent the Project is paid for, in whole or in part, with Bonds before the application to use PFC revenue is approved by FAA, the timing for the repayment of the Bonds for those parts of the Regional Concourse eligible for PFC funding will be subject to applicable laws and regulations. b. b. The Airline may obtain its own Interim Financing from a third party lender and proceed through the lender to fund a portion of the total program cost of the Regional Concourse not to exceed Thirteen Million Dollars ($13 million) and utilize the Authority's construction contract by making construction progress payments to the Authority. The provisions for the Airline's Interim Financing shall be by agreement between the Authority, the Airline, and the Airline's third party lender. The Authority shall fund the balance of the total program cost of the Regional Concourse with Bonds that will total no less than $4.7 million. The program cost of the Regional Concourse is estimated to total $17.7 million. The Authority will not add changes to the Regional Concourse that increase costs unless requested by the Airline and/or unforseen costs occur during construction. The Authority agrees that, upon the approval by the FAA to use PFC revenue for the Regional Concourse, provided such approval occurs no later than one year following the Substantial Completion Date of the Project, the Authority will take reasonable and prudent measures to replace the Airline's Interim Financing with its PFC Revenue Note up to the limit of the PFC funding allocated to the Regional Concourse and approved by the FAA. Should the FAA disapprove or not act on the Authority application within the one year period following the Substantial Completion Date of the Project, the Parties agree that the Authority shall be obligated to replace the Airline's Interim Financing with the proceeds of Bonds. Should the application to use PFC revenue for the Regional Concourse be subsequently approved by the FAA, the Authority will take reasonable and prudent measures to cause the repayment of that portion of the Bonds equal to the limit of the PFC funding allocated to the Regional Concourse and approved by the FAA, with the timing of such repayment of Bonds being subject to applicable laws and regulations. c. c. Should the Airline obtain its own Interim Financing to fund the construction of the Regional Concourse from a third party lender utilizing the Authority's construction contract by making construction progress payments to the Authority, the Authority agrees that it will recognize the interest of that lender in the Regional Concourse and it will execute documents to provide appropriate security for the lender upon the condition, however, that all rights acquired by the lender under such Interim Financing shall be subject to all of the covenants, conditions, and restrictions set forth in Agreement No. 4-90-A040, this Amendment No. 8, and any supplemental agreement entered into by the Authority, the Airline, and the lender providing the Interim Financing. 8. Hydrant Fueling. The Authority will plan, finance, design, and construct a hydrant fueling system to serve the 36 regional/commuter aircraft parking positions of the Regional Concourse as part of the work under the Project completed under paragraph 1.b. above. The costs of this addition to the hydrant fueling system shall not be part of the Project. The Airline agrees to make use of the hydrant fueling system through the Fueling Agent. 9. Maintenance. Maintenance responsibilities for the Regional Concourse and associated Aircraft Parking Positions by the Parties will be as provided for under Exhibit D-D of the Agreement. 10. Cancellation/Termination, Surrender of Premises. a. Notwithstanding that a portion of the Project is to be funded with PFC revenue, the Airline's right to terminate this Amendment No. 8 to Agreement No. 4-90-A040 shall be as specified in the Agreement with respect to Bond financed projects. Further, in addition to the rights of the Authority under Paragraph 2.02.2 of the Agreement, the Authority may, in its sole discretion, terminate the Airline's lease of Premises in the Regional Concourse and associated Aircraft Parking Positions, effective at midnight, December 31, 2004, or December 31 of any year thereafter during the period of the Agreement, provided that the Authority gives one hundred eighty (180) days written notice to the Airline and the Authority terminates the leases and the rights of all other Airlines using the Regional Concourse effective on the same date. b. The Authority may terminate the Airline's lease of Premises in the Regional Concourse and associated Aircraft Parking Positions without terminating the Agreement or leases of Premises elsewhere on the Airport. Article 14, "Surrender of Premises; Holding over," shall apply to any action under this paragraph 10. c. The Airline agrees that, in the event the Authority exercises the right of termination as described in this paragraph 10., the Airline shall be relieved on the date the Authority terminates the lease of Premises of any remaining unamortized costs of the Regional Concourse. 11. All terms and conditions of the Agreement, including the provisions of Article 17 regarding reallocation of Premises and accommodation of other Airlines, shall apply to the Regional Concourse, except that the date for periodic reallocation of Premises in the Regional Concourse, shall be the first anniversary of the Substantial Completion Date of the Regional Concourse or the next date for reallocation of Premises for the Airport in accordance with Section 17.02, whichever is the later date. 12. Any Project cost associated with environmental clean up of the Project site, if any (e.g., remediation of contaminated soil), shall be assigned to the Regional Concourse Sub-Center or to the Airfield Cost Center, as appropriate. IN WITNESS WHEREOF, the Parties hereto have executed this Amendment No. 8 as of the dates shown below.

The definitions in the Agreement apply to this Amendment No. 14 unless expressly stated otherwise. 2. Amendment No. 8 represents a prior agreement between the Parties on the subject of the Project and the financing thereof. This Amendment No. 14 represents the agreement of the Parties as of the date hereof and is a restatement of, and in furtherance of, the agreement reached in Amendment No. 8. In the event of any inconsistencies between the two Amendments, Amendment No. 8 and this Amendment No. 14 are to be construed so as to give full effect to this Amendment No. 14. 3. The Project. The Project for purposes of this Amendment No. 14 consists of the Regional Concourse, adjacent aircraft apron paving including Aircraft Parking Positions and other related improvements. a. The Authority will undertake and use its best efforts to plan, finance, design, construct, equip, operate and maintain a building, also known as the Regional Concourse, containing usual and customary facilities for accommodating passengers and their baggage, concessions, and other facilities to serve the Airline's passengers and others who are associated with the enplaning and deplaning of aircraft on the apron adjacent to the Regional Concourse. The Regional Concourse will be constructed to substantially conform to the drawings attached here to as Exhibit D-B-1 dated January 8, 1999, depicting the Regional Concourse and the apron. b. In conjunction with the Regional Concourse, the Authority will plan, finance, design and construct an aircraft parking apron adequate for the parking and movement of 36 regional/commuter aircraft. The apron when constructed will conform substantially to the drawing attached hereto as Exhibit D-B-1, dated January 8, 1999, depicting the Regional Concourse and the apron. The demarcation of the Aircraft Parking Positions will be proposed by the Airline and approved by the Airport Manager consistent with the Exhibit. 4. Lease of Permanent Premises. The Airline hereby commits to the Authority that, as of the Substantial Completion Date, as provided for in Section 6.02 of the Agreement, Lease of Permanent Premises and Equipment, the Airline, without the need for any further action, will lease from the Authority, subject to all of the terms and conditions herein, the following Permanent Premises: a. Type 2 Preferential Use Holdrooms - 24,480 square feet 203.02, 203.04, 204.03, 204.05, 205.10, and 205.12 b. Type 2 Exclusive Use Club - 204.09 1,330 square feet c. Type 2 Exclusive Use Admin.

Fitout of Space in the Regional Concourse. a. Consistent with paragraph 3 above, the Authority will furnish or contract to furnish all labor, materials, equipment and furnishings to fitout and furnish the public areas of the Regional Concourse, including: a) the gate holdrooms with public area seating, carpeting, public address system, and podium casework; b) the public corridors, stairways, elevators, and restrooms; c) mobile lounge docks; d) MUFIDS, and security equipment and cabling; e) canopies and walkways leading to the Aircraft Parking Positions; f) conduit and plugs for ground power units; and g) through its concessionaires, the concession areas. b. The Authority shall give written notice to the Airline of the estimated Substantial Completion Date of the Project at least one hundred and twenty (120) days prior to that date. Upon receipt of the notice of the estimated Substantial Completion Date, the Airline will be allowed to commence installation of its own equipment and furnishings and otherwise fitout and furnish its exclusively leased club, office, and operations Premises in the Regional Concourse. 6. Authority not liable for delay. The Authority shall not be liable to the Airline for failure to complete the Project or deliver possession of the Premises on the estimated Substantial Completion Date. The Authority will notify the Airline of any change in the estimated Substantial Completion Date and the Airline's obligations will remain as agreed to herein with the changed estimated Substantial Completion Date. Failure by the Airline to complete the fitout and furnishing of its exclusively leased Premises shall not delay the Substantial Completion Date for purposes of paragraph 7, below. 7. Substantial Completion Date. On the Substantial Completion Date of the Project, the date of which, unless changed by mutual agreement, shall not be sooner than one hundred and twenty (120) days after the notice given in paragraph 5.b. above, the following shall occur a. The Airline's lease of the Premises in the Regional Concourse described in paragraph 4, above, and associated Aircraft Parking Positions shall become effective. Exhibit D-B-1 and D-B-1A shall be deemed amended as of that date to add the Airline's Premises and associated Aircraft Parking Positions under the Agreement and all of the provisions, rights, privileges, obligations including rental charges and other fees, terms and conditions of the Agreement as amended shall apply. b. Provided that the Airline has otherwise satisfied all of its requirements for the Authority to issue a certificate of public occupancy, the Authority shall issue said certificate and the Airline may occupy its Premises in the Regional Concourse and associated Aircraft Parking Positions for purposes of conducting its Air Transportation Business. The Airline's failure to satisfy all of its requirements for the Authority to issue a certificate of public occupancy shall not delay the effective date of the lease of Premises in the Regional Concourse and associated Aircraft Parking Positions. 8. PFC and Airline Interim Financing. a. Pursuant to the Agreement of the Parties in Amendment No. 8 for the Airline to provide to the Authority interim financing for the Project in the absence of the approval by the United States Federal Aviation Administration (the "FAA") of a Passenger Facility Charge to finance the cost of the construction of certain eligible parts of the Project ("PFC Financing") (which PFC Financing is not available for the Project as of the date hereof due to no fault or failure of the Authority), the Parties hereby agree as follows with respect to certain interim funding for the Project. b. The Airline either will loan to the Authority, or facilitate the lending to the Authority, of up to $15.0 million to be utilized by the Authority to pay for a portion of the total costs of the Project including the Authority's program management costs (the "Project Costs"). The Airline will utilize the proceeds of a bridge loan (the "Bridge Loan") from Fleet Capital Corporation (the "Lender") to reimburse the Authority for Project Costs, on the terms and conditions provided herein. c. Bridge Loan proceeds shall be paid by the Airline to the Authority not later than the 14th day (or next business day) after receipt by the Airline of a notification (the "Notification") from the Authority that the Authority has incurred and paid Project Costs. In the Notification, the Authority shall (i) include a copy of the paid invoice(s) representing and confirming the actual payment of Project Costs by the Authority; (ii) certify and acknowledge the obligation of the Authority to repay the principal amount requested in the Notification, that the amount requested to be paid or reimbursed by the Airline constitutes the binding repayment obligation of the Authority to the Airline as provided for herein (a "Bridge Loan Obligation") as well as a Bridge Loan Obligation pursuant to, and as defined in, the January __, 1999, Escrow Agreement (the "Escrow Agreement") among the Airline, the Authority and Lender; and (iii) certify and acknowledge that all Project Costs included in the Notification actually have been incurred (and not prepaid) by the Authority in connection with the Project in accordance with all applicable contractual conditions and requirements. d. The Authority shall pay the balance of the total cost of the Project with PFC Financing, the proceeds of Bonds and/or an additional $1.0 million grant from the State of Virginia. The total cost of the Regional Concourse is reasonably estimated by the Authority at $21.7 million, and the Authority has no knowledge, or reason to believe, that the Regional Concourse cannot be completed for $21.7 million. The Authority will not add changes to the Regional Concourse that will materially increase costs without the consent of the Airline. There exists no material claim or dispute arising out of the Contract, any other material agreement concerning the Regional Concourse or with respect to the construction or completion of the Project. e. The repayment of the Lender shall be the Airline's obligation and responsibility subject only to the terms and conditions of the Escrow Agreement. The Authority may prepay the Bridge Loan Obligations in whole or in part at any time, or from time to time, without penalty and will repay to the Airline the entire then outstanding principal amount of the Bridge Loan Obligations without right of set- off, counterclaim or deduction on or before May 1, 2000, utilizing PFC Financing, Bond proceeds, the amount deposited in to escrow pursuant to the Escrow Agreement or other funds. The Authority will be responsible only for the repayment of the principal amount of the Bridge Loan Obligations and shall not be obligated to pay to the Airline or the Lender any interest thereon, or any expenses, charges, costs or amounts with respect thereto or arising out of the Bridge Loan, which shall remain the sole obligation of the Airline. f. Any amount paid to the Airline by, or on behalf of, the Authority with respect to the Bridge Loan Obligations shall be utilized by the Airline to repay its principal obligation on the Bridge Loan to the Lender with one business day of receipt from the Authority. g. The Airline acknowledges that the Authority has submitted a PFC Application to the FAA for PFC funding of the Project and is using its reasonable best efforts to cause the PFC Application to be approved. In the event any PFC Financing which is obtained is inadequate to repay the entire amount of the Bridge Loan Obligations which either then or subsequently are outstanding, the Authority shall remain obligated pursuant to the terms of this Amendment No. 14 and the Escrow Agreement for the balance of any Bridge Loan Obligations. In the event the FAA has disapproved, or failed to act on the PFC Application on or before the date which is one year after the Substantial Completion Date of the Regional Concourse, the Authority may repay the Bridge Loan Obligations with the proceeds of Bonds. Provided, however, in the event that the Authority has given Notification to the Airline in accordance with paragraph 8.c. above and payment is not received by the Authority on or before the 14th day after Notification, the Authority may expend Bond funds on costs that were the subject of the Notification. 9. Provisions of Airline Bridge Loan, Security, and Defaulta. In furtherance of Amendment No. 8, paragraph 7.c., the Authority will deposit $15 million with an escrow agent pursuant and subject to the terms of the Escrow Agreement to provide security to the Lender for the Bridge Loan Obligations in the event of a default by the Airline under the Bridge Loan or, in the event the Bridge Loan Obligations are not otherwise repaid on or before May 1, 2000, to provide for repayment of the Bridge Loan Obligations by the Authority to the Airline, in each case as set forth in the Escrow Agreement. The Lender shall only have such rights as against the Authority as are expressly set forth in the Escrow Agreement. b. Nothing contained herein, in the Escrow Agreement or otherwise shall preclude the Airline, the Lender and the Authority from agreeing that the Authority will pay the Bridge Loan Obligations directly to the Lender and that acceptance thereof by the Lender and the application of such payment by the Lender to the obligations of the Airline with respect to the Bridge Loan shall constitute full performance by the Authority and that no additional amount to the Airline from the Authority will be due and owing under this Amendment No. 14. c. Any claim by the Lender against the Airline or the Authority for any amount in excess of the amount placed in escrow for any interest due on the Bridge Loan Obligations, or for any penalty, damages, or fine, shall be the responsibility of the Airline and not an obligation of the Authority. d. Upon the payment by the Authority of the amount of the Airline's Bridge Loan as provided for herein with the proceeds of Bonds or PFC Secured Funds, the Authority shall adjust the Airline's rates and charges as provided for under Article 8 of the Agreement and paragraph 10 of this Amendment 14 and the Airline shall pay the adjusted amount due, if any, as provided for under the Agreement. e. In addition to its obligations under Article 12 of the Agreement, the Airline shall defend, indemnify, and hold the Authority and its agents, officers, and employees completely harmless from and against any and all claims, suits, demands, actions, liabilities, losses, damages, judgments, or fines arising from its Bridge Loan. f. In furtherance of Section 19.14.1 of the Agreement, this Amendment and any agreement for the Bridge Loan is expressly subordinated and subject to the pledges, transfer, hypothecation or assignment made by the Authority in any prior Indenture or Indenture hereafter entered into to issue Bonds. g. The Airline shall not place any lien upon the Project, or against any Premises Equipment or any rents or fees due from the Airline to the Authority without the express written consent of the Authority. h. By the terms of an agreement among the Authority, the Airline and the Lender the provisions hereof may be modified. 10. Rates and Charges. a. For purposes of determining rates and charges under Section 8.03 of the Agreement, the Regional Concourse will be a separate Terminal and Equipment Sub-Center ("Regional Concourse Sub-Center"). All Authority costs to design, finance, construct, operate and maintain the Regional Concourse, as described under paragraph 3.a. above, and those additional Authority costs allocated to the Regional Concourse under the methodology of Article 8 of the Agreement will be allocated to the Regional Concourse Sub- Center for purposes of determining rates and charges. b. Except as provided in paragraph 11 herein, all other Authority costs to design, finance, construct, and maintain the aircraft movement and parking areas serving the Regional Concourse, as described under paragraph 3.b. above, including the additional Authority costs allocated under the methodology of Article 8 of the Agreement, will be included in the Airfield Cost Center for Washington Dulles International Airport. The Airline will be responsible for the Aircraft Parking Position Charges as provided for in Section 8.04. of the Agreement for the use of the aircraft parking areas serving the Regional Concourse. Three regional/commuter aircraft parking positions (Exhibit D-B-1, Sheet 1) will be equivalent to one narrow-body air carrier aircraft parking position for the purpose of assessing the Aircraft Parking Position Charges associated with the Regional Concourse. c. Attachment A provides an estimate of rates and charges for the Regional Concourse assuming (i) expenditures of $5.7 million in Bonds by the Authority, $1.0 million grant from the Commonwealth of Virginia, and Airline Interim Financing of $15 million; (ii) the same as (i) except that PFC secured funds are used to repay the Airline for the Interim Financing, or; (iii) the same as (i) except that the proceeds of Bonds are used to repay the Airline for the Interim Financing. Exhibit D-B-1A (IAD) will be revised to include the rental due for the lease of the Premises constructed under the Project effective on the Substantial Completion Date. Attachment B presents an estimate of rentals and charges that will be due for the additional Premises and the Aircraft Parking Positions in the format of Exhibit D-B-1A (IAD). The amortization period for any Bond financing shall be the life of the Bonds as is provided for with other Bond funded facilities and terminal projects under the Authority's Capital Development Program.1. Hydrant Fueling. The Authority will plan, finance, design, and construct a hydrant fueling system ("the Fueling System") to serve the aircraft parking apron of the Regional Concourse. The costs of this addition to the Fueling System shall be recovered by the Authority from the charges assessed to all users of the Fueling System. 12. Maintenance. Maintenance responsibilities for the Regional Concourse and associated Aircraft Parking Positions by the Parties will be allocated as provided for under Exhibit D-D of the Agreement. 13. Cancellation/Termination, Surrender of Premises. a. Notwithstanding that a portion of the Project is to be funded with PFC revenue, the Airline's right to terminate its lease of Premises constructed under the Project shall be to the same extent as its right to terminate this Agreement No. 4-90-A040 while Bonds are outstanding. 14. All terms and conditions of the Agreement, including the provisions of Article 2 regarding termination and Article 17 regarding reallocation of Premises and accommodation of other Airlines, shall apply to the Regional Concourse, except that the date for periodic reallocation of Premises in the Regional Concourse shall be the second anniversary of the Substantial Completion Date of the Regional Concourse or the next date for reallocation of Premises for the Airport in accordance with Section 17.02, whichever is the later date. 15. Any Project cost associated with environmental clean up of the Project site, if any (e.g., remediation of contaminated soil), shall be assigned to the Regional Concourse Sub-Center as a cost of site preparation or to the Airfield Cost Center, or the Aviation Cost Center as appropriate. 16. Mobile Lounge Service to the Regional Concourse The Authority's responsibilities to provide regular shuttle-type mobile lounge service as provided for under Article 7.01.7 of the Agreement shall include such service between the Main Terminal and the Regional Concourse commencing on the Substantial Completion Date. 17. All other terms and conditions of the Agreement remain unchanged. 18. This Amendment No. 14 shall be effective upon the signature of the Parties.

WHEREAS, the Airline and the Authority agree that the Airline is responsible for making these improvements known as "Fitout Improvements," and that the Airline's Eligible Costs thereof (Eligible Costs) shall be paid by the Authority as part of the Capital Development Program and recovered from the Airline by the Authority through the Equipment Cost Center identified in Section 8.01(4)(i)(f) of the Agreement; NOW THEREFORE, the Parties hereto agree as follows: 1. The effective date of this Amendment shall be February 1, 1999. 2. Section 10.09, Improvements by the Airline, is amended by adding the following paragraph at the end of the section: Section 10.09.7 - The Fitout Improvements listed in paragraph (ii) to this Amendment shall be constructed by the Airline. The Eligible Costs of these Fitout Improvements shall be reimbursed to the Airline by the Authority in accordance with the following: (i) The Airline shall select and enter into contracts with an architect/engineer and a construction contractor to accomplish the Fitout Improvements. The Authority shall not be a party to these contracts. Airline shall submit for review a copy of each contract for which reimbursement will be requested This shall be accomplished prior to reimbursement for work performed under that contract. (ii) The Airline's construction contracts for the Fitout Improvements shall require completion of the Fitout Improvements by a certain date, which date shall not be after May 2, 1999, provided that the Authority makes the Premises available to the Airline for Fitout Improvements on or before November 9, 1998. Provided further, that for every day the Authority delays in making particular Premises available to the Airline, the date by which the Airlines must complete the Fitout Improvements for those Premises is extended one day The Authority's rights to move the Airline into Temporary Airline Premises, or Permanent Airline Premises, in accordance with Article 5, and the rights of the other Signatory Airlines to move into Permanent Airline Premises, shall not be diminished by the failure of the Airline to complete its Fitout Improvements. The Airline's acknowledges that time is of the essence and that the failure to complete the Fitout on or before May 2, 1999, may result in the Airline's Permanent Airline Premises not being substantially complete and that the substantial completion date of the Airline's Permanent Premises may, therefore, be delayed. The Airline's contracts to accomplish the Fitout Improvements shall contain provisions requiring the retention of 10 percent of its contractor's billings pending final acceptance by the Airline of the Fitout Improvements. The Airline shall take all reasonable actions necessary to enforce timely completion of the Fitout Improvements. (iii) The Authority shall reimburse the Airline for the Eligible Cost of the Fitout Improvements incurred by the Airline up to a maximum of $1,000,000 for Dulles. The Eligible Cost to be reimbursed by the Authority include amounts paid by the Airline for all construction, equipment, and material costs for the Fitout Improvement such as ceilings; walls; flooring; windows; doors; mechanical, electrical, and utility systems and connections and outlets; cabinets and mill work; and any other equipment and finish work attached to and made a permanent part of the Premises; and any taxes and freight costs directly attributed to the Fitout. The reimbursement would also include the reasonable amounts paid to architects and engineers. All invoices should be submitted no later than May 2, 2000. (iv) The following are not Eligible Costs: the cost of any Airline operating facilities, as specified in the Agreement, Article 3.01, including furniture, furnishings, special light fixtures, carpeting, draperies, wall coverings, decorations, decorating or other special finishing work, appliance, trade fixtures and equipment that is owned, furnished, installed and used by the airline in its operation at the Airport. The cost of Airline personnel and overhead costs of any Airline are not Eligible Costs. (v) Any Fitout Improvement costs incurred by the Airline in excess of the maximum stated above shall be the responsibility of the Airline and shall not be an Eligible Cost. (vi) The Authority shall reimburse the Airline in accordance with the payment procedures stated herein. The Airline will establish a separate bank checking account to be used exclusively for payment of Eligible Costs of reimbursable Fitout Improvement Cost. Checks drawn upon this account shall require the signature of both the Airline and the Authority regardless of the amount. The Authority shall make timely deposits of principal funds into the account in amounts sufficient to cover checks drawn on the account. Any interest earned by the account, less the amount of any bank charges against the account, including any penalties assessed by the bank for failure of the Authority to deposit sufficient funds into the account to cover checks, shall belong to the Authority and may be withdrawn by the Authority at any time after it has been credited to the account by the bank. Further, funds remaining in the account after payment of Eligible Costs shall belong to the Authority to the extent that the Authority deposited principal into the account in excess of the reimbursable Fitout Improvement costs. (vii) The Airline shall be responsible for providing to the Authority complete documentation of the Fitout Improvements and costs for which reimbursement is sought showing that the work has been performed in an acceptable manner and that payment is due to the contractor(s). Failure to provide such documentation in a timely manner may delay payment to the Airline's contractor(s). (viii) Monthly progress payments shall be made on the basis of Eligible costs incurred or on estimates thereof as provided by the contractor and approved by the Airline and the Authority's contracting officer. The Airline shall require the contractor to submit an invoice to the Airline. The Airline has the responsibility to determine the amount to be paid. The Airline will mail a signed check, drawn on the account described herein payable to the contractor with an original and three copies of the contractor's invoice to the following address: Metropolitan Washington Airports Authority Accounting Operations Department, MA-22B 44 Canal Center Plaza Alexandria, VA 22314-1562 The Authority reserves the right to recommend to the Airline a reduction in the payment to the contractor for noncompliance with Airport regulations, the terms of this Agreement, as amended or other specified reasons. The final decision regarding any reduction in payment is the responsibility of the Airline. The reason for any reduction from the contractor's invoice amount by the Airline shall be stated in writing and attached to the invoice. (ix) The Authority's Design Manual, revised as of July 1997 (including Appendices 1-3), is to be employed by the Airline in making the Fitout Improvements. (x) All contractors and subcontractors working on Fitout Improvements must enroll in the Authority's Owner Controlled Wrap-Up Insurance Program (OCWIP). Eligibility and enrollment procedures are defined in the OCWIP Manual, which is available from the Authority. (xii) The Airline shall take no action inconsistent with Article 19.14.2 of the Agreement pertaining to the Authority's compliance with the Internal Revenue Code of 1986. (xiii) The Authority strongly encourages the use of Minority and Women Business Enterprises (MBE/WBE) for the Fitout Improvements, regardless of the size or location of the MBE/WBE. The Local Disadvantaged Business Enterprise's (LDBE) participation is also strongly encouraged, with a goal of 25 percent LDBE participation. The Airline agrees to contact the Authority's Equal Opportunity Programs Department at (703) 417-8625 to pursue MBE/WBE/LDBE participation. All other terms and conditions of the Agreement remain unchanged. IN WITNESS WHEREOF, the Parties hereto have executed this Amendment. METROPOLITAN WASHINGTON AIRPORTS AUTHORITY By: James A.
