AIRFIELD AREA FACILITIES 
  

	2.01	AIRFIELD AREA FACILITIES TO BE PROVIDED 

 The City agrees to provide, operate and
maintain in good condition and repair at the Airport, in accordance with good airport maintenance practices, and to make available for use by aircraft operators, the Airfield Area Facilities shown upon the attached drawing of the Airport marked
Exhibit A, which drawing is incorporated herein and made a part hereof by reference, and any additions or extensions thereto. 
 The
City may from time to time make alterations to, or reconstruct, or relocate, or modify the design and type of construction of, or close the Airfield Area Facilities, or any portion or portions of them, either temporarily or permanently, provided
that reasonably equivalent Airfield Area Facilities are made available to the Airline. 
  

	2.02	USE OF AIRFIELD AREA FACILITIES 

 The airlines shall be entitled to use the Airfield Area
Facilities for the following purposes: 
 (A) Runways for the purpose of landing and taking off of aircraft. 

(B) Taxiways for the purpose of ground movement of aircraft. 

(C) Passenger ramp and apron areas, including, without limitation, the Airline’s preferential use areas shown on Exhibit C
attached hereto (“Preferential Use Passenger Aircraft Ramp and Apron Areas”) for the purpose of unloading and loading passengers, baggage, freight, mail, supplies, and cargo to and from aircraft; for the purposes of performing such fueling
and other ramp services as is more extensively defined in Section 2.03; for the purpose of parking mobile equipment while being actively used in connection with ramp operations, or for any other such purpose and, in connection with
Airline’s Preferential Use Passenger Aircraft Ramp and Apron Areas, for coordinating and directing the parking and pushback of aircraft; but aircraft carrying property, cargo, and mail, but not passengers, shall use ramp areas designated for
cargo operations by the Manager. 
 (D) Training operations of the Airline. 

(E) Any other use normally incident to the foregoing. 

The use of the Airfield Area Facilities shall be in common with others authorized by the City to do so, upon compliance with reasonable and
nondiscriminatory terms and conditions (including the payment of rates, fees, and charges) upon which they are made available for such use, and in accordance with Airport Rules and Regulations. 

  
 3 









	2.03	RAMP SERVICES 

 Airline shall have the right to use the Airline’s Preferential Use
Passenger Aircraft Ramp and Apron Areas to provide services for aircraft occupying loading or unloading positions (herein called “ramp services”) incidental to the immediate preparation of aircraft for scheduled operations, such services
to include, among others, fueling, inspection, interior cleaning and non- routine maintenance (defined as minor repairs and the replacement or adjustment of equipment of an emergency nature, or in order to
insure the safe departure of the aircraft), unless otherwise authorized by the Manager. Ramp services and facilities may be provided at loading and unloading positions in accordance with the Airport Rules and Regulations. The Airline shall leave the
ramp area used by it for any such purposes in a neat, clean, safe and orderly condition upon completion of such services. 
 The Airline
shall have the right to perform its own ramp services or to have such services performed by a regular ramp contractor (i.e., a person authorized by the Manager to perform ramp services at the Airport for any and all aircraft operations). If all such
regular ramp contractors are unsatisfactory to the Airline from the standpoint of service or price, the Airline may notify the Manager that it desires to use the services of a contractor not authorized and the Manager may approve such contractor to
perform such services; provided however, that the contractor shall accept a permit from the Manager upon the same terms and conditions as regular ramp contractors (except that at the option of the Manager, there may be omitted from such permit any
provision requiring or permitting the contractor to serve others than the Airline). The Airline shall have the right to perform or receive ramp services, including refueling, for or from any other air carrier certificated to serve Denver, except
that the location of ramp services outside the receiving airline’s Preferential Use Facilities shall be determined by the Manager. No charges, fees or tolls of any nature shall be imposed by the City, directly or indirectly, against the Airline
or such other air carrier for the right or privilege of providing or receiving such ramp services. 
  

	2.04	RATES, FEES AND CHARGES FOR THE USE OF THE AIRFIELD AREA FACILITIES 

 The rates, fees and
charges for the use of the Airfield Area Facilities shall be as established from time to time by the City in accordance with this Agreement. For each landing of an aircraft by the Airline at the Airport, Airline shall be assessed a landing fee in an
amount equal to the number of thousands of pounds of maximum allowable gross landing weight of that aircraft, multiplied by the landing fee rate. The landing weight data will be compiled by the Airport through the use of an independent Radar based
landing fee activity database. Airlines will access a secure website where a summary and detailed monthly activity report and applicable landing fee charges will be available by the 5th day of the month. The Airport will send an invoice by the 7th day of the month. The rates, fees and charges for the use of the Airfield Area shall be payable no later than twenty (20) days after the close of each calendar month of the term hereof. 

  
 4 








 The maximum allowable gross landing weight shall be determined based on the current FAA Type
Certificate Data Sheet applicable to the particular type, design, and model of aircraft. 
 PART III 

LEASE AND USE OF DEMISED PREMISES AND PREFERENTIAL USE FACILITIES 

 

	3.01	DEMISED PREMISES 

 The City hereby leases to the Airline and the Airline hereby agrees to
lease from the City space in the passenger terminal building and concourses at the Airport designated on Exhibit D (which drawings are incorporated herein and made a part hereof by reference) (collectively, the “Demised Premises”).
The City and Airline acknowledge and agree that the dimensions of the Demised Premises as set forth in Exhibit D are defined as part of this Agreement. It is acknowledged and agreed that the Demised Premises under this Agreement constitute non- residential real property. Except to the extent required for the performance of the obligations of the Airline hereunder, nothing contained in this Agreement shall grant to the Airline any rights whatsoever in
the air space above the Demised Premises except as approved by the City. 
  

	3.02	USE OF DEMISED PREMISES 

 The Airline shall have the use of the portion of the Demised
Premises designated in Exhibit D as “Demised Premises” during the term of the letting thereof, for the following purposes, purposes reasonably related thereto and for such other purposes as may be authorized in writing from time to
time by the Manager: 
 (A) The handling of reservations, ticketing, billing and manifesting of passengers for air transportation; 

(B) The clearance, checking-in, handling of outbound and inbound baggage and baggage claim, and the
rendering of similar services to passengers for air transportation, and for the furnishing of information, including but not limited to, flight arrival, flight departure and baggage claim information to passengers and to the general public; 

(C) Administrative offices, operations offices, employee lockers and restrooms, baggage, cargo and mail-handling and storage facilities and
equipment; such uses and facilities to be located within Airline’s Demised Premises; 
 (D) Radio, data processing and other
communication equipment; 
 (E) The assembling, handling and disbursing of baggage and lost and found articles; 

(F) The operation, by Airline or an independent contractor, of passenger clubs and lounges where the Airline may serve food and beverage with
or without charge; such uses and facilities to be located within Airline’s Demised Premises; and 
 (G) The installation, maintenance,
and operation of facilities and equipment reasonably necessary or convenient to carry out any or all of the foregoing. 

  
 5 









	3.03	EFFICIENCY-IN-USE 


The Airline agrees to make every reasonable effort to offer to any other incoming or incumbent airline the opportunity to share use of its
Demised Premises. In determining whether the use by another incoming or incumbent airline is reasonable and possible, the Airline will have the right to consider the compatibility of the proposed operation of the incoming or incumbent airline with
those of the Airline, the operations of those with whom the Airline has subleases or handling agreements, the Airline’s existing and immediate future flight schedules, the need for labor harmony, and the availability of other similar premises
at the Airport. Should the Airline refuse another airline the opportunity to use the Airline’s Demised Premises, the City and County of Denver, acting by and through its Manager, may review the Airline’s Demised Premises usage, and should
the Manager reasonably determine, considering all the factors noted herein and any other reasonable justification presented by Airline, including the Airline’s reasons for such refusal, that the Airline unreasonably refused usage by such other
airline, the Manager may immediately require the Airline to permit the incoming or incumbent airline to use that part of the Airline’s Demised Premises and for those periods of time the City deems feasible, subject to the incoming or incumbent
airline executing a mutually acceptable agreement with the Airline, and subject to the Manager’s review and approval of said agreement. 
  

	3.04	PAYMENT OF FIXED AND VARIABLE RATES, FEES AND CHARGES 

 (A) Rentals for the Demised
Premises and Preferential Use Facilities shall be paid in twelve (12) equal monthly installments, and shall be due and payable, in advance, without notice on or before the first day of the then current month. 

(B) In addition to the fixed rates, fees, and charges provided herein, Airline shall pay for other common use facilities, equipment, services
and maintenance utilized by Airline. Said rates, fees and charges shall be paid monthly, in advance, and adjusted, if necessary, based on such actual costs. Any additional amount due from the Airline or refund owed to the Airline, as the case may
be, based on such actual costs, shall be paid by the Airline or credited by the City, as the case may be, to rates, fees and charges. Such services may include, but are not limited to, industrial waste, sewer and water and trash. 

 

	3.05	USE OF PREFERENTIAL USE FACILITIES ON CONCOURSES 

 The City hereby grants to the Airline
preferential use of certain concourse facilities as designated in Exhibit C and Exhibit D where so indicated. The right of preferential use includes the right of the Airline and its Affiliated Airlines to enplane and deplane passengers and to
schedule and use such facilities as defined herein, subject to the conditions set forth herein and in the Airport Rules and Regulations regarding the operation and use of concourses as such reasonable and nondiscriminatory rules and regulations
exist or may be promulgated in the future. The right of preferential use is expressly understood to be a non-exclusive right, and the City retains the right to allow other airlines the use of the
Airline’s preferential use areas to the extent such other use does not infringe on the Airline’s preferential use as herein defined. 

Furthermore, it is expressly agreed and understood that the foregoing right of preferential use is not a property right and shall not be
assigned, subleased or otherwise alienated or 

  
 6 








 
hypothecated in any manner whatsoever by the Airline; except that, in the case of a merger of Airline with another airline or the acquisition of substantially all of Airline’s assets by
another airline, Airline’s preferential use shall be transferable to the surviving airline. 
 The Airline’s preferential use and
scheduling rights on its passenger holdroom(s), associated passenger loading bridges, gate(s) and Preferential Use Passenger Aircraft Ramp and Apron Areas (collectively, the “Preferential Use Gates”), are subject to the following
requirements (“Preferential Use Gate Usage Requirements”): 
 (A) ***** 

 

	 	(1)	***** 

  

	 	(2)	***** 

  

	 	(3)	***** 

  

	 	(4)	***** 

  

	 	(5)	***** 

 (B) In the event Airline performs Ground Handling (as defined in Airport Rules and
Regulations) for other parties, such activities count as departures for purposes of this gate usage requirement. 
 (C) If Airline fails to
meet the minimum Preferential Use Gate Usage Requirements for a calendar quarter, without excuse, the Manager may notify Airline that it is in violation of this Agreement, and may return to the Airport’s unassigned gate inventory, the number of
Airline’s concourse-level Preferential Use Gates failing to meet Airline’s Preferential Gate Use Requirements. Airline shall have 10 business days from receipt of such notice to specify which Preferential Use Gates are to be returned;
provided, however, that the Manager may select different Preferential Use Gates as may be necessary to create contiguity with other unleased gates. 

(D) Upon Airline’s request, the Manager in its sole discretion may waive preferential status with corresponding rent reductions to
airline-leased space. As long as the space remains in Airline’s leasehold, the Airline may provide the City with 90 days written notice and reclaim such space for Airline’s own use, to sublet to another party for their use, or to perform
Ground Handling services for another party on that gate. 
 (E) Airline agrees to abide by reasonable and nondiscriminatory rules and
regulations regarding the operation and use of concourses as such rules and regulations exist or may be promulgated in the future in the Airport Rules and Regulations. The City will provide not less than 21 days’ notice to Airline when any rule
or regulation affecting Airline is proposed for amendment, and will post amendments when final. 

  

	*****	Confidential portions of the material have been omitted and filed separately with the Securities and Exchange Commission.

	3.06	USE OF AND ACCESS TO BAGGAGE SYSTEM 

 The City hereby grants to the Airline a license to
use the Baggage System on a common use basis, for the purpose of loading and unloading baggage to and from aircraft, and access to the Baggage System for activities reasonably necessary or convenient in connection with the foregoing. The grant of
such license and the use of and access to the Baggage System is more specifically set forth in a Baggage System License Agreement between City and Airline. The Airline acknowledges and agrees that the Baggage System shall be managed, operated, and
maintained for the benefit of the air carriers by an operator selected by the City and the Signatory Airlines. The Airline’s use of and access to the Baggage System shall be conducted so as not to interfere with the safe and efficient operation
of the Baggage System by the operator. 
 The parties agree that certain baggage belt areas behind ticket counters in the Terminal Building
which are part of the Airline’s Demised Premises shall be considered exclusively leased to the Airline for the purpose of passenger operations, but nonetheless those baggage belts are part of the Baggage System for the purpose of operation and
maintenance, in accordance with the terms and conditions of the City’s agreement with the operator. 
  

	3.07	USE OF PUBLIC AREAS 

 Airline and its employees, agents, passengers and invitees, its
suppliers of materials and furnishers of services shall have the non-exclusive right to use, in common with all others, all public areas of the Airport, together with all improvements, facilities and equipment
located therein, including, without limitation, the following: passenger transit systems, passenger walkways, public lobbies, public waiting rooms, public stairways, elevators and escalators, public restrooms, public roads and parking lots. Nothing
herein shall be deemed to convey to Airline any interest or property rights in such public areas, or to any improvements thereto. 
 PART
IV 
 PROVISIONS RELATING TO AIRFIELD AREA FACILITIES, PREFERENTIAL USE 

FACILITIES, DEMISED PREMISES, AND JOINT USE FACILITIES 
  

	4.01	MAINTENANCE 

 (A) The City shall provide services and maintenance in the Airfield Area
Facilities, Preferential Use Facilities, Demised Premises and Joint Use Facilities as indicated in Exhibit E, attached hereto and made a part hereof, and shall bear the cost thereof in consideration of payment to be made by the Airline
pursuant to the provisions hereof. 
 (B) The Airline agrees that it will at all times under its control maintain its Preferential Use
Facilities, Demised Premises and Joint Use Facilities in a neat, clean, safe and orderly condition, in compliance with the requirements of 42 U.S.C. § 12101 et seq., 49 U.S.C. § 41705, and 14 C.F.R. Part 382, and in keeping with the
general decor of the area in which they are situated, and that it will perform those maintenance services shown on said Exhibit E to be performed by the Airline.

 The Airline may, with prior written approval of
the Manager, at its own cost and expense, install in the Demised Premises any fixture or improvement or do or make alterations or do remodeling, germane to the use herein or hereafter granted. Any fixtures, improvements, equipment and other property
installed, erected or placed by the Airline in, on or about such Demised Premises shall be deemed to be personal and shall be and remain the property of the Airline, except as otherwise provided herein and the Airline shall have the right at any
time during the term hereof to remove any or all of its property, subject to the Airline’s obligation to repair damage, if any, resulting from such removal. All such fixtures, improvements, equipment and other property shall be removed from the
said Demised Premises by the expiration or earlier termination of letting and the Demised Premises restored to the condition existing at the time of the letting, reasonable wear and tear excepted, unless the City, acting by and through its Manager,
shall have advised the Airline in writing at the time of such installation or not less than sixty (60) days in advance of such expiration or not less than thirty (30) days in advance of such earlier termination, of its willingness to
accept title to such fixtures, improvements, equipment and other property in lieu of restoration of the Demised Premises. It is understood and agreed that during such period and until such personal property is removed, the Airline shall pay to the
City the full rental applicable to those Demised Premises, as determined by the Manager, which are directly associated with said personal property and which Demised Premises are not usable by others until said personal property is removed. 

Said improvements, and all alterations thereof and additions thereto, shall in all respects be constructed in accordance with the ordinances
and any applicable code or rule and regulation of the City and County of Denver, including the Airport Rules and Regulations governing tenant construction specifications and other non-technical requirements,
in accordance with the attached Exhibit G, “Design Standards, Construction Procedures and Environmental Requirements,” which is incorporated herein by reference, in accordance with the requirements of 42 U.S.C. § 12101
et seq., 49 U.S.C. § 41705, and 14 C.F.R. Part 382, and pursuant to any required building permit to be obtained from the City and according to the customary terms and conditions thereof. 

 

	4.03	SUB-LETTING, ASSIGNMENT AND GROUND HANDLING ARRANGEMENTS 


No interest or rights under this Agreement may be transferred except as provided under this Section 4.03 

Airline may sublet, assign or otherwise transfer the Demised Premises, in whole or in part to another airline, or use the Demised Premises for
the handling by Airline’s personnel of air transportation operations of other airlines, subject, however, to each of the following conditions: 

(A) No sub-lease, assignment, ground handling agreement or other transfer shall relieve Airline from
primary liability for any of its obligations hereunder, and Airline shall continue to remain primarily liable for the payment of rentals, fees and charges applicable to such premises and facilities hereunder; 

  
 9 








 (B) Airline shall provide written notice to the City and a copy of the proposed sublease,
assignment, ground handling agreement or other transfer not less than thirty (30) days prior to the effective date of such arrangement; 

(C) Any sublease, assignment, ground handling agreement or other transfer shall be subject to the prior written approval of the Manager; and

 (D) Unless a gate sharing agreement is in place as authorized by the Manager under Airport Rules and Regulations, any authorization by
Airline for use of a Preferential Use Gate by another airline shall require such other airline to remit directly to the City a non-preferential use gate fee as established by the Airport Rules and Regulations.
All such fees shall be credited in the calculation of rentals, rates, fees and charges. 
  

	4.04	RIGHT TO ENTER AND MAKE REPAIRS 

 The City and its authorized officers, employees,
agents, contractors, subcontractors and other representatives shall have the right (at such times as may be reasonable under the circumstances and with as little interruption to the Airline’s operations as is reasonably practicable) to enter
upon the Demised Premises for the following purposes: 
 (A) To inspect the Demised Premises at reasonable intervals during regular business
hours (or at any time in case of emergency) to determine whether the Airline has complied and is complying with the terms and conditions of this Agreement with respect to the Demised Premises. 

(B) To perform maintenance and make repairs and replacements in any case where the Airline is obligated to do so and has failed after
reasonable notice to do so, in which event the Airline shall promptly upon demand reimburse the City for the actual cost thereof, plus a 15% administrative charge. 

(C) To perform maintenance and make repairs and replacements in any case where the City is obligated to do so, and in any other case where the
City, in its reasonable judgment, determines that it is necessary or desirable to do so in order to preserve the structural safety of the Demised Premises or the building in which they are located or to correct any condition likely to cause injuries
or damages to persons or property. 
 (D) In the exercise of the City’s police power. 

No such entry by or on behalf of the City upon such Demised Premises leased to Airline shall cause or constitute a termination of the letting
thereof or be deemed to constitute an interference with the possession thereof by the Airline. 
  

	4.05	ABANDONMENT OF DEMISED PREMISES 

 If the Airline ceases to occupy and use a material
portion of the Demised Premises for a continuous period of six (6) consecutive months or longer, the City, acting by and through the Manager, may consider such portion of the Demised Premises abandoned, and if needed for another use, upon not
less than thirty (30) days’ written notice to the Airline, terminate the lease for such portion of the Demised Premises. 

  
 10 









	4.06	DESTRUCTION OF PREMISES 

 If by reason of any cause Airline’s Demised Premises, or
any portion thereof, are damaged or destroyed by fire or other casualty, then: 
 (A) The City, after consultation with Airline, shall
forthwith repair, reconstruct and restore the damaged or destroyed portions of the Demised Premises to substantially the same condition, character, utility and value as existed prior to such damage or destruction, unless the City and Airline agree
that no such reconstruction is necessary, or that reconstruction to some other condition, character, utility and value is appropriate or desired; and 

(B) If such Demised Premises are damaged to such an extent that the Demised Premises are untenable, the City, acting by and through the
Manager, will make all reasonable efforts to provide substantially equivalent substitute premises and facilities, and such substitute premises and facilities will be made available to Airline consistent with those rentals, fees and charges for the
use of the Airport established and modified from time to time by the City in accordance with this Agreement. 
 (C) For portions of the
Demised Premises that are untenable, Airline shall receive a pro rata abatement of rentals, fees and charges applicable thereof from the date of such occurrence to the date upon which such portions of the Demised Premises are repaired and restored.

  

	4.07	COMMON USE SYSTEMS 

 Prior to implementation of multiple or common use systems, the City
will consult with Airline. Thereafter, upon nine (9) months advance written notice by the City, the Airline agrees that it will make all necessary modifications and improvements to become compatible with the City’s multiple or common use
system installations. After the City installs common use systems, all future improvements and any new equipment of the Airline shall be compatible with the City’s multiple or common use system installations. The Airline shall not install any
proprietary terminal equipment without the prior written approval of the Manager. 
  

	4.08	REASSIGNMENT OF DEMISED PREMISES AND PREFERENTIAL USE FACILITIES 

 After consultation
with all affected airlines, in order to maximize the highest and best use of the City’s airline facilities, the City may at its sole discretion, relocate and reassign the Airline’s use and lease of the Demised Premises and Preferential Use
Facilities upon sixty (60) days advance written notice. The City will be responsible for reasonable costs related to any such relocations and/or reassignments.

 PART V 

GENERAL PROVISIONS 
  

	5.01	AGREEMENTS WITH THE UNITED STATES 

 This agreement is subject and subordinate to the
provisions of any agreements between the City and the United States relative to the operation or maintenance of the Airport, the execution of which has been or may be required as a condition precedent to the transfer of federal rights or property to
the City for airport purposes, or to the expenditure of federal funds for the extension, expansion or development of the Airport, including the expenditure of federal funds for the development of the Airport in accordance with the provisions of the
Airport and Airway Improvement Act of 1982, as amended. The provisions in the attached Appendices 1 and 2 are hereby incorporated herein by reference. 
  

	5.02	BOND ORDINANCES 

 This Agreement is in all respects subject and subordinate to any and
all City bond ordinances applicable to the Airport and airport system and to any other bond ordinances which should amend, supplement or replace such bond ordinances. 

The parties to this Agreement acknowledge and agree that all property subject to this Agreement which was financed by the net proceeds of tax-exempt bonds is owned by the City, and Airline agrees not to take any action that would impair, or omit to take any action required to confirm, the treatment of such property as owned by the City for purposes of
Section 142(b) of the Internal Revenue Code of 1986, as amended. In particular, the Airline agrees to make, and hereby makes, an irrevocable election (binding on itself and all successors in interest under this Agreement) not to claim depreciation
or an investment credit with respect to any property subject to this Agreement which was financed by the net proceeds of tax-exempt bonds and shall execute such forms and take such other action as the City may
request in order to implement such election. 
  

	5.03	LAWS, REGULATIONS, AND AGREEMENTS TO BE OBSERVED 

 (A) The Airline shall not use, or
authorize the use by any other person or party, of all or any portion of the Demised Premises, or any part of the Airport to which it is granted a right of use or occupancy by this Agreement, for any purpose or use other than those authorized by
this Agreement, or hereafter authorized in writing by the Manager. No use shall be considered authorized by this Agreement if such use would adversely affect the tax-exempt status of Airport Revenue Bonds.

 (B) The Airline shall comply with and shall cause its officers and employees and any other persons over whom it has control to comply
with the Airport Rules and Regulations. 
 (C) The Airline shall, at all times, faithfully obey and comply with all existing laws, rules and
regulations adopted by federal, state, local or other governmental bodies and applicable to or affecting the Airline and its operations and activities in and at the Airport, including 49 U.S.C. § 41705 (the Air Carrier Access Act) and
implementing regulations at 14 C.F.R., Part 382, and 42 U.S.C. § 12101 et seq. (the Americans with Disabilities Act) and implementing regulations. 

  
 12 








 (D) It is agreed that any disputes regarding laws, ordinances, rules and regulations regarding
the Airport issued by the City shall first be presented to administrative hearing before the Manager or the Manager’s authorized representative following the procedure outlined in Denver Revised Municipal Code
Section 5-17. It is further agreed that no action shall be brought against the City contesting any such laws, ordinances, rules and regulations until there has been full compliance with the terms of said
section 5-17. Nothing herein shall be construed to prevent Airline from contesting in good faith any laws, ordinances, rules or regulations without being considered in breach hereof during such time as is
required to exhaust the administrative hearing procedures, so long as such contest is diligently commenced and prosecuted by Airline. 

PART VI 
 RATE-MAKING
PROCEDURES AND REESTABLISHMENT 
  

	6.01	GENERAL PROVISIONS 

 The City agrees that it will establish and fix airline rentals,
rates, fees and charges in accordance with the cost- accounting concepts and rate-making procedures described in attached Exhibit F. Further, the City agrees that said rentals, rates, fees and charges shall be reasonable in relation to the
cost of providing, operating and maintaining the services or facilities used or leased by the Airline. The City acknowledges its obligations to charge air carriers nondiscriminatory and substantially comparable rates, fees, rentals and other
charges, subject to reasonable classification such as tenant and non-tenant, Signatory and non-Signatory (as such is defined herein). The City agrees that it will not
enter into an Airport Use and Facilities Lease Agreement with another air carrier which is substantially more favorable, unless the same rights, terms, and privileges are offered to the Airline. 

Airline acknowledges that the rate base for rentals, fees and charges must generate gross revenues, which together with Other Available Funds
(as defined in the General Bond Ordinance) must be sufficient to satisfy the Rate Maintenance Covenant of the General Bond Ordinance, and Airline agrees to pay such rentals, rates, fees and charges. 

The City, acting by and through its Manager, may from time to time reestablish the rentals, rates, fees and other charges for the use of
Airport in accordance with the concepts and rate-making procedures provided for herein. 
 The City, acting by and through its Manager, may
from time to time, amend the rate- making concepts and procedures set forth in this Agreement with the written consent of a majority of the Signatory Airlines not in default of the Agreement, represented by: (1) a numerical majority; and
(2) a majority in terms of rentals, rates, fees and charges paid in the preceding fiscal year. 

  
 13 









	6.02	NON-AIRLINE REVENUE 

 In order to minimize the
rentals, rates, fees and charges which Airline is obligated to pay under this Agreement, the City shall promote and develop non-airline revenues at the Airport in a manner consistent with that of a reasonably
prudent airport operator. 
  

	6.03	PROJECTION OF RENTALS, RATES, FEES AND CHARGES 

 Not later than forty five (45) days
prior to the end of each Fiscal Year during the term of this Agreement, City shall furnish Airline with a projection of the rentals, rates, fees and charges for the next ensuing year for each cost center of Airport. Such projection will include the
Airport proposed expense budget, and projection of aircraft operations, passenger enplanements, and debt service payments for the ensuing year. The City shall convene a meeting with the Signatory Airlines operating at the Airport not later than
thirty (30) days prior to the end of each Fiscal Year to consult and review with the Signatory Airlines the projection of rentals, fees and charges for the next ensuing year. 

 

	6.04	MID-YEAR REVIEW OF RENTALS, RATES, FEES AND CHARGES 


Not later than September 1st of each year, the City shall furnish the Airline with a projection of rentals, rates, fees and charges (the Mid-Year Projection), which shall reflect the most recently available information on current aircraft operations and passengers enplaned as well as expenses actually incurred and revenues realized thus far during
such fiscal year. The City shall provide a pro forma projection of revenues and expenses for the current fiscal year. The City shall convene a meeting with the Signatory Airlines operating at the Airport to consult and review the Mid-Year Projection and any adjustment to the monthly rentals, rates, fees and charges for such fiscal year. 
  

	6.05	FINAL AUDIT 

 Upon release by the City’s independent auditors of the audited
financial statements of Airport, the City shall furnish Airline with a copy of the annual audit report, prepared in accordance with Generally Accepted Accounting Principles and certified by an independent accountant, covering the operation of the
Airport for such preceding fiscal year. As soon as practical following the release of the annual audit report, the City will prepare an analysis of additional charges or credit due (Year-End Settlement) along
with the Airline Revenue Credit calculation to Airline for the preceding audited fiscal year. If the rentals, fees and charges paid by Airline were greater than the respective amounts chargeable to Airline, Airline shall receive credits promptly in
the amount of such overpayment against future rentals, fees and charges. If the rentals, fees and charges paid by Airline were less than the respective amounts chargeable to Airline, Airline shall pay promptly the amount of any such deficiency. 

 

	6.06	PASSENGER FACILITY CHARGES 

 (A) “Passenger Facility Charges” or
“PFCs” are charges collected by the Airline pursuant to the authority granted by the Aviation Safety and Capacity Expansion Act of 1990, 49 U.S.C. Section 40117, and 14 CFR Part 158, as amended. Airline acknowledges that PFCs are
funds held for the benefit of the City. Airline further acknowledges that PFCs are not property of 

  
 14 








 
the Airline under any of the circumstances described in paragraph 7.02(D) herein. Airline agrees that under the circumstances described in paragraph 7.02(D) herein, Airline will immediately
establish a fund and segregate PFC funds collected as required by 49 U.S.C. Section 40117(m)(1). 
 (B) Airline shall abide
by the remittance, reporting and recordkeeping requirements of PFCs as outlined in 14 CFR Part 158 and referenced in Airport Rules and Regulations, and the Airport shall abide by the public agency requirements outlined in
14 CFR Part 158. 
 PART VII

shall terminate on December 31, 2016, unless this Agreement is earlier cancelled, terminated, or extended as hereinafter provided. 
  

	7.02	TERMINATION OF LEASE BY CITY 

 The City, acting by and through its Manager, may declare
this Agreement terminated in part or in its entirety, as the Manager deems appropriate, upon the happening of any one or more of the following events and may exercise all rights of entry and reentry with or without process of law, without liability
for trespass upon the Preferential Use Facilities and Demised Premises: 
 (A) If the rentals, rates, fees, charges or other money payment
which the Airline herein agrees to pay, or any part thereof, shall be unpaid after the date the same shall become due; or 
 (B) If the
Airline shall use or permit the use of the Preferential Use Facilities and Demised Premises covered hereby at any time for any purpose for which the use thereof at that time is not authorized by this Agreement or by the subsequent written consent of
the Manager, or shall use or permit the use thereof in violation of any law, rule or regulation to which the Airline has agreed in this Agreement to conform; or 

(C) If Airline shall be in violation of any provision of Section 4.03 with respect to the subletting of the Demised Premises hereunder;
or 
 (D) If, during the term of this Agreement, the Airline shall (a) apply for or consent to, in writing signed on behalf of the
Airline by any of its officers or its duly authorized attorney, the appointment of a receiver, trustee or liquidator of the Airline or of all or a substantial part of its assets, (b) file a voluntary petition in bankruptcy, or admit in writing
its inability to pay its debts as they come due, (c) make a general transfer for the benefit of creditors, (d) file a petition or an answer seeking reorganization or arrangement with creditors or to take advantage of an insolvency law, or
(e) file an answer admitting the material allegations of a petition filed against the Airline in any bankruptcy, reorganization or insolvency proceeding, or if during the term of this Agreement an order, judgment or decree shall be entered by
any court of competent jurisdiction, on the application of a creditor, adjudicating the Airline as bankrupt or as insolvent, 

  
 15 








 
or approving a petition seeking a reorganization of Airline or of all or a substantial part of its assets, and such order, judgment, or decree shall continue unstayed and in effect for any period
of ninety (90) consecutive days, then, and in any of such events, the City may give to the Airline a notice of intention to end the term of this Agreement in its entirety after the expiration of thirty (30) days from the date of service of
such notice, and on the date set forth in said notice the term of this Agreement and all right, title and interest of Airline hereunder shall expire as fully and completely as if that day were the date herein specifically fixed for the expiration of
the term, and the Airline will then voluntarily and peaceably quit and surrender the Preferential Use Facilities and Demised Premises covered hereby to the City, but the Airline shall remain liable as herein provided; or 

(E) If Airline fails to make its Preferential Use Facilities and Demised Premises available for use in accordance with 56 Fed. Reg. 24, 254-01 (1991) (codified at 14 C.F.R. 158, App. A, B.7), but any right to terminate by the City under this section 7.02 (E) may be exercised only with respect to the portion of the Exclusive Use Premises required by
56 Fed. Reg. 24, 254-01 (1991) (codified at 14 C.F.R. 158, App. A, B.7). 
 (F) If any of
Airline’s directors or officers assigned to or responsible for operations at the Airport shall be or have been convicted of any crime which is a disqualifying offense under 49 CFR 1544 governing issuance of airport security badges. 

 

	7.03	TERMINATION OF LEASE BY AIRLINE 

 The Airline, at its option, may declare this Agreement
terminated in part or in its entirety upon the happening of any one or more of the following events: 
 (A) If by any reason of any action
or non-action of any federal or other governmental agency having jurisdiction to grant a certificate of convenience and necessity, or similar document, authorizing the Airline to operate aircraft in or out of
the Airport (including action in the nature of alteration, amendment, modification, suspension, cancellation or revocation of any such certificate, permit or document), the Airline shall cease to have authority to operate aircraft in and out of the
Airport pursuant to such a certificate or document, provided that (1) such governmental action or non-action was not requested by the Airline, and the Airline made all reasonable efforts to prevent such
governmental action or non-action, or in the alternate, (2) the City had a reasonable opportunity to appear before such federal or governmental agency and be heard in opposition to such governmental
action or non-action prior to the occurrence, if it desired to do so or, in the alternate, (3) the Airline gave the City reasonable advance notice that such governmental action or non-action was being requested or might occur, and the Airline made a reasonable effort to the end that the City might have an opportunity to appear and be heard as aforesaid; or 

(B) If by legislative action of the United States the Airline is deprived of such certificate of similar document; or 

(C) If a court of competent jurisdiction issues an injunction or restraining order against the City or any successor body to the City
preventing or restraining the Airport for airport purposes in its entirety, or the use of any part thereof which may be used by the Airline and which is substantially necessary to the Airline for its operations, and if such injunction remains in
force for a period of ninety (90) days or more and is not stayed by appeal or a writ of error; or 

  
 16 








 (D) If the City’s operation of Airport is substantially restricted by action of any federal
or other governmental agency having jurisdiction with respect thereto, or the occurrence of any fire or other casualty substantially and adversely affects, for a period of at least ninety (90) days, Airline’s use of Airport in the conduct
of its air transportation business; provided, however, none of the foregoing is due primarily to any fault of Airline. 
  

	7.04	EFFECTIVE DATE OF TERMINATION 

 Notwithstanding anything to the contrary in this
Agreement, no termination declared by either party shall be effective until not less than thirty (30) days have elapsed after written notice to the other specifying the date upon which such termination shall take effect and the cause for which
it is being terminated (and if such termination is by reason of a default under this Agreement for which termination is authorized, specifying such default with reasonable certainty). No such termination shall be effective if such cause shall have
been cured or obviated during such thirty (30) day period, or in the event such cause is a default under this Agreement (for which termination is authorized) and if by its nature such default cannot be cured within such thirty (30) day
period, such termination shall not be effective if the party in default commences to correct such default within said thirty (30) days and corrects the same as promptly as reasonably practicable; provided that the thirty (30) day period
shall not apply to termination declared for failure of Airline to make money payments hereunder, for which termination may be declared by the City upon fifteen (15) days’ written notice, unless Airline remedies such default within such
fifteen (15) day period; and provided further that the Airline will be allowed only two (2) notices of default with respect to money payments in any one year which it may cure. Upon termination of this Agreement, the parties hereto shall
be relieved from all obligations hereunder except as set forth in Sections 6.05, 7.05, 7.06, 8.02, 10.08, 10.14, and 10.15. The right of any party hereto to terminate this Agreement shall not in any manner affect or limit such party’s right to
exercise any other right or remedy it may have rather than its right of termination. 
  

	7.05	SURRENDER AND HOLDING OVER 

 The Airline covenants that at the expiration of the period
for which the Demised Premises are leased to it, or at the earlier termination of the letting thereof, it will quit and surrender such Demised Premises in good state and condition, reasonable wear and tear, acts of God or other casualty and damage
due to the negligent or willful act or omission of the City excepted, and except as otherwise provided in Section 4.02, the Airline shall forthwith remove there from all equipment, trade fixtures and personal property belonging to it. The City
shall have the right on such termination to enter upon and take possession of such Demised Premises with or without process of law, without liability for trespass. 

Holding over by Airline following the expiration of the term of this Agreement or any extension thereof, without an express agreement as to
such holding over, shall be deemed and taken to be a periodic tenancy from month-to-month. The Airline shall be subject to all the terms and conditions of this Agreement
as amended from time to time or any extension thereof. Rent, fees and charges for each month of such holding over shall be paid as provided herein and in a 

  
 17 








 sum equal to the monthly rental required for the month prior to the end of the term of this Agreement or as
reestablished as provided for herein. In the event Airline fails to surrender the Preferential Use Facilities and Demised Premises upon termination or expiration of this Agreement, or such month-to-month tenancy, then Airline shall indemnify City against loss or liability resulting from any delay of Airline in not surrendering same. 

 

	7.06	TERMINATION OF HOLDOVER 

 If Airline holds over pursuant to Section 7.05 hereof,
either party may, with or without cause, cancel or terminate said tenancy by giving not less than thirty (30) days written notice to the other party. Said notice shall set out the date of such cancellation and termination. 

PART VIII 
 PERFORMANCE
BOND, INDEMNIFICATION AND INSURANCE 
  

	8.01	PERFORMANCE BOND 

 Unless otherwise provided by Airport Rules and Regulations, as they
may be adopted or amended from time to time, upon the commencement of the term of this Agreement, the Airline shall deliver to the Manager for the City and County of Denver, and shall maintain in effect at all times during the term of this
Agreement, including a period of ***** after expiration (or earlier termination of the letting of the Demised Premises hereunder) of said Agreement, a valid corporate Performance Bond, or an irrevocable Letter of Credit, in the amount of *****, or
an amount equal to *****, whichever is less, payable without condition to the City and County of Denver, with surety acceptable to and approved by the City’s Manager, which bond or irrevocable letter of credit shall guarantee to the City full
and faithful performance of all of the terms and provisions of this Agreement to be performed by the Airline, and as said Agreement may be amended, supplemented or extended. 

Notwithstanding the foregoing, if at any time during the term hereof, the Manager deems the amount of the surety insufficient to properly
protect the City from loss hereunder because the Airline is or has been in arrears with respect to such obligations or because the Airline has, in the opinion of the Manager, violated other terms of this Agreement, the Airline agrees that it will,
after receipt of notice, increase the surety to an amount required by the Manager; provided however, the percentage increase in the amount of surety shall not exceed the annual percentage increase that has occurred with respect to the Airline’s
rental and fee rates in effect under this Agreement. 
  

	8.02	INDEMNIFICATION 

 The Airline agrees to indemnify and save harmless the City, its
officers, and employees, from and against (A) any and all loss of or damage to property, or injuries to, or death of, any person or persons, including property and officers, employees and agents of the City; and (B) all claims, damages,
suits, costs, expense, penalties, liability, actions or proceedings of any kind or nature whatsoever, of or by anyone whomsoever; which, with respect to clauses (A) and (B) hereof, in any way result from, or arise out of, Airline’s
operations in connection herewith, or its use or occupancy of any portion of the Airport and the acts, omissions, or wrongful conduct of officers, employees, agents, contractors or subcontractors of the Airline including without 

  

	*****	Confidential portions of the material have been omitted and filed separately with the Securities and Exchange Commission. 



  
 18 








 limitation, the provision or failure to provide security as herein required and the use, disposal, generation,
transportation or release of pollutants, including but not limited to oil, glycol, toxic or hazardous materials at Denver International Airport by the Airline, its contractors, employees, agents, customers, or anyone claiming or acting by or through
the Airline. 
 Airline further agrees that if a prohibited incursion into the Air Operations Area occurs, or the safety or security of the
Air Operations Area, the Airfield, the Baggage System or other sterile area safety or security area is breached by or due to the negligence or willful act or omission of any of Airline’s employees, agents, or contractors and such incursion or
breach results in a civil penalty action being brought against the City by the U.S. Government, Airline agrees to reimburse the City for all expenses, including attorney fees, incurred by the City in defending against the civil penalty action and
for any civil penalty or settlement amount paid by the City as a result of such incursion or breach of airfield or sterile area security. The City shall notify Airline of any allegation, investigation, or proposed or actual civil penalty sought by
the U.S. Government for such incursion or breach. Civil penalties and settlement and associated expenses reimbursable under this Paragraph include but are not limited to those paid or incurred as a result of violation of Federal Aviation
Administration (FAA) regulations or Transportation Security Administration (TSA) regulations, as they may be amended, or any similar law or regulations intended to replace or compliment such regulations. 

Without limitation, the terms of this indemnity include an agreement by Airline to indemnify, defend and hold harmless the City from and
against any and all expense, loss, claim, damage, or liability suffered by City by reason of Airline’s breach of any environmental requirement existing under federal, state or local law, regulation, order or other legal requirement in
connection with any of Airline’s acts, omissions, operations or uses of property relating to this Agreement, or such a breach by the act or omission of any of Airline’s officers, employees, agents, or invitees, whether direct or indirect,
or foreseen or unforeseen, including (but not limited to) all cleanup and remedial costs actually and reasonably incurred to satisfy any applicable remediation obligation required by federal, state or local law, and reasonable legal fees and costs
incurred by City in connection with enforcement of this provision, but excluding damages solely relating to diminution in value of City real property. 

Provided however, the City agrees that (I) the Airline need not save harmless or indemnify the City against damage to or loss of
property, or injury to or death of persons, caused by the negligence or willful acts of the City, its officers, employees, contractors and agents, and (II) the City will give prompt written notice to the Airline of any claim or suit and the
Airline shall have the right to assume the defense and compromise or settle the same to the extent of its own interest. Provided, however, the indemnity provided for herein shall apply only to the extent the City is not reimbursed out of insurance
proceeds. 
  

	8.03	INSURANCE MAINTAINED BY AIRLINE 

 At all time during the term of this Agreement, unless
otherwise required by federal or state governmental law or regulation, the Airline is required and agrees, at its own cost and expense, to provide and keep in force for the benefit of the Airline and the City, a policy, or policies, of insurance
written on a single limit each occurrence basis with limits of not less than Three Hundred Million Dollars ($300,000,000.00) for bodily injury and property damage arising 

  
 19 








 
from any operation of the Airline at the Airport and contractual liability coverage. The Manager may increase the limit of insurance required when, in her discretion, she deems the amount stated
herein is insufficient. The Manager may establish lesser amounts of insurance for airlines operating exclusively with aircraft of thirty (30) seats or less. 

Such insurance policy, or policies, and certificates of insurance evidencing the existence thereof shall cover all operations of the Airline
at the Airport, shall be in a form and written by a company, or companies, approved by the Airport’s Risk Manager and shall insure the Airline’s agreement to indemnify the City as set forth in the indemnification provisions hereof. The

its business at and upon said Airport, and further agrees not to permit any of said taxes, excises or license fees to become delinquent. The Airline further covenants and agrees at all times to maintain adequate Worker’s Compensation Insurance
in accordance with any present or future Colorado law with an authorized insurance company, or through the Colorado State Compensation Insurance Fund, or through an authorized self- insurance plan approved by the State of Colorado insuring the

obligations incurred by it in connection with its operation of said business on the Airport, and not to permit the same to become delinquent and to suffer no lien, mortgage, judgment or execution to be filed against said premises or improvements
thereon which will in any way impair the rights of the City under this Agreement. The Airline shall have the right on giving the City prior written notice to contest any such mechanic’s, materialman’s or any other lien, and the Airline

 If the Airline shall in good faith proceed to contest any such tax, assessment or other public
charge, or the validity thereof, by proper legal proceedings which shall operate to prevent the collection thereof or to prevent the appointment of a receiver because of nonpayment of any such taxes, assessments or other public charges, the Airline
shall not be required to pay, discharge or remove any such tax, assessment or other public charge so long as such proceeding is pending and undisposed of; provided, however, that the Airline, not less than five (5) days before any such tax,
assessment or charge shall become delinquent, shall give notice to the City of the Airline’s intention to contest its validity. If such notice is so given by the Airline to the City and such contest is conducted in good faith by the Airline,
the City shall not, pending the termination of such legal proceedings, pay, remove or discharge such tax, assessment or other charge. 
  

	8.05	LOSS OR DAMAGE TO PROPERTY

claim for any such loss or damage at any time. 
  

	8.06	FORCE MAJEURE 

 Neither the City nor the Airline shall be deemed to be in breach of this
Agreement by reason of failure to perform any of its obligations under this Agreement if, while and to the extent that such failure is due to embargoes, shortages of materials, acts of God, acts of the public enemy, acts of superior governmental
authority, sabotage, strikes, boycotts, labor disputes, weather conditions, riots, rebellion and any circumstances for which it is not responsible and which are not within its reasonable control. This provision shall not apply to failures by the
Airline to pay rents, fees or other charges, or to make any other money payment whatsoever required by this Agreement, except in those cases where provision is made in this Agreement for the abatement of such rents, fees, charges or payments under
such circumstances. 
  

	8.07	INSURANCE MAINTAINED BY THE CITY 

 Miscellaneous Insurance. The City shall at all
times carry with a responsible insurance company or companies authorized and qualified under the laws of the State to assume the risk thereof: 

(A) Fire and Extended Coverage Insurance. From and after the time when any contractors engaged in connection with the Airport, or any
part thereof, shall cease to be responsible pursuant to the provisions of their respective contracts for loss or damage thereto occurring from any cause, the City shall insure and at all times keep the Airport insured to the extent possible with a
responsible insurance company, companies or carriers authorized and qualified under the laws of the State of Colorado assume the risk thereof against direct physical damage or loss from fire and so-called
extended coverage perils in an amount not less than 

  
 21 








 ***** of the replacement value of the Facilities so insured, less depreciation; but such amount of insurance
shall at all times be sufficient to comply with any legal or contractual requirement which, if breached, would result in assumption by the City of a portion of any loss or damage as co-insurer; and also if at
any time the City shall be unable to obtain such insurance to the extent above required at reasonable cost as determined by the Manager, the City shall maintain such insurance to the extent reasonably obtainable. Insurance against any other risks or
type of loss as are or shall be customarily covered may be obtained, under a standard “all risk policy” with extended coverage for public property, or otherwise, including, without limitation, insurance against loss or damage to the
Airport by flood or other waters, elements of weather, explosion of any nature, earthquake, and volcanic eruption (or any combination thereof), when, if, and to the extent any such insurance can be procured at reasonable rates in the sole opinion of
the Manager. 
 (B) Loss of Use Insurance. To the extent not provided for in leases and other agreements between the City and others
relating to the Airport, insurance covering loss of revenues from Airport facilities by reason of necessary interruption, total or partial, in the use thereof, resulting from damage thereto or destruction thereof, however caused, in such amount as
is estimated to be sufficient to provide a full normal income during the period of suspension; but 
 (1) Such insurance shall cover a
period of suspension of the period of reconstruction as estimated by the Airport Engineer, but not less than twelve months; 
 (2) Such
insurance may exclude losses sustained by the City during the first seven days of any total or partial interruption of use; and 
 (3) If at
any time the City shall be unable to obtain such insurance to the extent above required, it shall carry such insurance to the extent reasonably obtainable at reasonable rates in the sole option of the Manager. 

In any calculation of the full normal income for such insurance, consideration shall be given to the expected, as well as current and prior,
revenues from such Airport facilities, or from other sources, and may also make allowances for any probable decrease in the operation and maintenance expenses or any other charges and expenses while use is interrupted. Any proceeds of such insurance
shall be deposited to the credit of the Revenue Fund and shall be subject to the uses of and shall be applied as provided for moneys in the Revenue Fund. 

(C) Liability Insurance. Insurance in the form and amount recommended by the Manager and reasonably sufficient to insure against
liability to any individual sustaining bodily injury or any person sustaining property damage or the death of any individual by reason of any defect or want of repair in or about the Airport, or by reason of the negligence of any employees, and
against such other liability for individuals, including workmen’s compensation insurance, to the extent attributed to ownership and operation of the Airport, and damage to property of persons; but in the case of the company or companies
insuring the Airport under a general liability policy against loss from bodily injury or property damage, or both, the total liability of such company or companies for all damages because of all bodily injury and all property damage arising out of
continuous or repeated exposure to substantially the same general conditions to which the policy applies as the result of any one occurrence, subject to such exclusions generally

other like provision of the policy, regardless of the number of: 
 (1) Insureds under the policy, 

(2) Individuals who sustain bodily injury or persons who sustain property damage, 

(3) Claims made or suits brought on account of bodily injury or property damage, or 

(4) Occurrences. 
 (D)
Maintenance of Policies. All such insurance policies designated in Subparagraphs (A) and (B) hereof shall be filed with the Manager and shall be subject to inspection at all reasonable times by Airline. If the Manager determines that
certain insurance required in Subparagraphs (A) and (B) hereof cannot be obtained to the extent therein required at reasonable rates, the Manager shall prepare a written memorandum to that effect, designating each such type of insurance in
question and stating in each such case that the insurance was not obtainable or that designated insurance was required in substitution for the required insurance, the reason or reasons for its substitution, and when and to the extent that the
substituted insurance was procured at reasonable rates, as the case may be. Each such memorandum shall be filed with the policies on file with the Manager and shall also be subject to such inspection.

Airport. The City shall consult with Airline prior to taking any such action which would adversely affect the Airline’s operations at the Airport unless such action is necessitated by circumstances which in the opinion of the Manager pose an
immediate threat to the health and safety of persons using the Airport. The Airline agrees that no liability shall attach to the City, its officers, agents, employees, contractors, subcontractors and representatives by reason of minor inconvenience

 EXHIBIT G 

Design Standards, Construction Procedures and 

Environmental Requirements 

Section 1 Design Standards. The Airline agrees to utilize and comply with the Denver International
Airport Design Standards Manuals for design of the Facilities. The Airline further agrees to design, construct, and operate the Facilities in accordance with the Denver International Airport Tenant Development Guidelines and the Denver International
Airport Rules and Regulations, as they may be established or amended from time to time, and any other applicable design, construction, operation, and maintenance standards. See additional information at
http://business.flydenver.com/bizops/bizRequirements.asp 
 All civil design drawings submitted by the Airline to the City shall be provided
and submitted according to FAA requirements in Advisory Circular AC150/5300-18B GIS Standards: Collection of airport data through field and post processing methodologies are specified in this FAA
Advisory Circular. The data model specifies the following Geographical Information System (GIS) feature groups: Airfield, Airspace, Cadastral, Environmental, Geospatial, Man Made Structures, Navigational Aids, Seaplane, Security, Surface
Transportation, and Utilities. The model incorporates safety critical data including runway thresholds, navigational aids as well as other airport features including runways, taxiways, aprons, buildings, roadways, cadastral, land-uses, and
utilities. The single GIS airport database will serve numerous needs and therefore requires a very robust set of data features and associated attributes. As a result, significant time and effort is required to collect and input the metadata (data
about data). The power of an airport GIS database is derived from the metadata. The long term application of airport GIS data collection methodology will reduce survey costs, errors, and missing data. 

To facilitate these FAA requirements GIS/CADD data submittals shall adhere to the data standards set forth in DIA Design Standards Manual 12
(DSM 12). CADD/GIS files must be submitted that are compatible with the FAA’s AGIS database and includes all features required by the FAA relevant to the project. Each feature shall be fully and accurately attributed according to the
specifications of FAA AC 150/5300-18B. Any files rejected by the FAA must be corrected and resubmitted to DIA’s Project Manager until satisfactorily accepted by the FAA. Final CADD survey data required
for FAA submission should adhere to the standards provided in DSM 12. 
 Approval of the City shall extend to and include consideration of
architectural and aesthetic matters and the City reserves the right to reject any designs submitted and to require the Airline to resubmit designs and layout proposals until they meet with the City’s approval. 

In the event of disapproval by the City of any portion of the plans and specifications, the Airline shall promptly submit necessary
modifications and revisions thereof. 
 Section 2 Construction Procedures. All construction work
shall comply with the requirements of and standards established by the City and all other appropriate governmental agencies and entities. 

  
 G-1 








 The City shall at all times have the right to monitor and inspect the construction of the
Facilities and all site improvements to assure that the Facilities and all site improvements are constructed and installed in compliance with the Plans and Specifications.
