**ITEM 1. BUSINESS**

**General**

Through SkyWest Airlines, our primary operating entity, we offer scheduled passenger service to destinations in the United States, Canada and Mexico. Substantially all of our flights are operated as United Express, Delta Connection, American Eagle or Alaska Airlines flights under code-share agreements with United, Delta, American or Alaska, respectively. Code-share agreements are commercial agreements between airlines that, among other things, allow one airline to use another airline's flight designator codes on its flights. As of December 31, 2025, we offered approximately 2,260 daily departures, of which approximately 940 were United Express flights, 680 were Delta Connection flights, 420 were American Eagle flights and 210 were Alaska Airlines flights.

We generally provide regional flying to our major airline partners under long-term, fixed-fee, code-share agreements. Under these fixed-fee agreements (commonly referred to as "capacity purchase agreements"), our major airline partners generally pay us fixed rates for operating the aircraft primarily based on the number of completed flights, flight time and the number of aircraft under contract. The major airline partners either directly pay for or reimburse us for specified direct operating expenses, including fuel expenses. Our operations are conducted principally at airports that support our major airline partners' route networks, including Chicago (O'Hare), Dallas, Denver, Detroit, Houston, Los Angeles, Minneapolis, Phoenix, Salt Lake City, San Francisco and Seattle.

We conduct our code-share operations with our major airline partners pursuant to various code-share agreements described under the heading "Code-Share Agreements" below.

**Fleet**

SkyWest has been flying since 1972. During our long operating history, we have developed an industry-leading reputation for providing quality regional airline service. As of December 31, 2025, our fleet consisted of aircraft manufactured by Embraer S.A. ("Embraer"), including the E175 regional jet aircraft ("E175"), and aircraft manufactured by MHI RJ Aviation ULC, formerly known as Bombardier Aerospace ("Bombardier"), including the Canadair CRJ900 regional jet aircraft ("CRJ900"), the Canadair CRJ700 regional jet aircraft ("CRJ700"), including a 50-seat configuration of the CRJ700 aircraft, commonly referred to as a "CRJ550" and the Canadair CRJ200 regional jet aircraft ("CRJ200"). As of December 31, 2025, we had 637 total aircraft in our fleet, including 487 aircraft in scheduled service or under contract pursuant to our code-share agreements, summarized as follows:

---

| | | | | | |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) As of December 31, 2025, other aircraft included: supplemental spare aircraft supporting our code-share agreements that may be placed under future code-share or leasing agreements, aircraft scheduled to be placed under a code-share agreement with one of our major airline partners or aircraft that are scheduled to be disassembled for use as spare parts.

Bombardier and Embraer are the primary manufacturers of regional jets operated in the United States and offer many of the amenities of larger commercial jet aircraft, including flight attendant service, a stand-up cabin, overhead and

[**Table of Contents**](#Toc)

under seat storage, lavatories and in-flight snack and beverage service. The Bombardier CRJ900, CRJ700 and CRJ550 aircraft and the Embraer E175 aircraft we operate under our code-share agreements are configured with a first-class seating section. The Bombardier CRJ200 aircraft we operate under our code-share agreements are configured in a 50-seat configuration with single-class seating. The speed of Bombardier and Embraer regional jets is comparable to larger aircraft operated by major airlines, and they have a range of approximately 1,600 miles and 2,100 miles, respectively. As of December 31, 2025, our fleet seat configuration by aircraft type is summarized as follows:

---

| | | |
|:---|:---|:---|
| **Manufacturer** | **Aircraft Type** | **Seat Configuration** |
| Embraer | E175s  | 70-76 |
| Bombardier | CRJ900s | 70-76 |
| Bombardier | CRJ550/CRJ700s | 50-70 |
| Bombardier | CRJ200s | 30-50 |

---

**SkyWest Leasing**

SkyWest Leasing is a reportable segment that includes revenue associated with our financing of new aircraft with debt under our capacity purchase agreements, currently consisting of our E175 aircraft, and the depreciation and interest expense of our E175 aircraft. The SkyWest Leasing segment additionally includes the revenue and expense from leasing aircraft and engines to third parties. The SkyWest Leasing segment's total assets and capital expenditures include the acquired E175 aircraft and aircraft and engines leased to third parties.

As of December 31, 2025, SkyWest Leasing leased 40 CRJ700 aircraft, five CRJ900 aircraft and regional jet aircraft engines to third parties.

**SkyWest Charter (SWC)**

In 2022, we formed a new subsidiary, SWC, which began operations in 2023. SWC offers on-demand charter service using CRJ200 aircraft in a 30-seat configuration. As of December 31, 2025, SWC had 11 aircraft available for on-demand charter service. In September 2025, the U.S. Department of Transportation (the "DOT") granted SWC authorization to operate as a commuter air carrier. We are evaluating opportunities to use SWC as a commuter air carrier.

**Competition and Economic Conditions**

The airline industry is highly competitive. We compete principally with other regional airlines. Our operations extend throughout most major geographic markets in the United States. Our competition includes, therefore, nearly every other domestic regional airline. Our primary competitors include CommuteAir, Inc.; Endeavor Air, Inc. ("Endeavor") (owned by Delta); Envoy Air Inc. ("Envoy"), PSA Airlines, Inc. ("PSA") and Piedmont Airlines ("Piedmont") (Envoy, PSA and Piedmont are owned by American); Horizon Air Industries, Inc. ("Horizon") (owned by Alaska Air Group, Inc.); GoJet Airlines, LLC ("GoJet"); and Republic Airways Holdings Inc. ("Republic"). Major airlines typically award code-share flying agreements to regional airlines based primarily upon the following criteria: ability to fly contracted schedules, availability of labor resources, including pilots, low operating cost, financial resources, geographical infrastructure, overall customer service levels relating to on-time arrival and flight completion percentages and the overall image of the regional airline. Additionally, each major airline may be limited in the number and type of regional aircraft it may use in its network due to agreements the major airline has with its own labor groups, commonly referred to in the industry as "scope limitations." Given our major airline partners' scope limitations, we currently do not operate a regional aircraft configured with more than 76 seats.

The principal competitive factors for regional airline code-share agreements include labor resources, code-share agreement terms, reliable flight operations, operating cost structure, ability to finance new aircraft, certification to operate certain aircraft types and geographical infrastructure supporting markets and routes served.

Our operations represent the largest regional airline operations in the United States. However, regional carriers owned by major airlines may have access to greater resources than we do through their parent companies.

Generally, the airline industry is sensitive to changes in general economic conditions. Economic downturns, combined with competitive pressures, have contributed to a number of reorganizations, bankruptcies, liquidations and business combinations among major and regional carriers. The effect of economic downturns may be somewhat mitigated by our predominantly contract-based flying agreements. If, however, any of our major airline partners

[**Table of Contents**](#Toc)

experience a prolonged decline in the number of passengers or are negatively affected by low ticket prices or high fuel prices, they may seek rate reductions in future code-share agreements, or materially reduce scheduled flights in order to reduce their costs. In addition, adverse weather conditions can impact our ability to complete scheduled flights and can have a negative impact on our operations and financial condition. Also, major airline scope limitations may restrict certain fleet-type growth opportunities for the regional carriers. Additionally, attrition of our pilots or other workgroups may reduce our flying schedules and have a negative impact on our operations and financial condition.

**Impact of Regional Airline Captain Availability on Production**

As passenger demand in the airline industry recovered from the COVID-19 pandemic in 2020, the number of regional airline captains and first officers hired by major airlines and low-cost carriers significantly increased. As a result, we experienced a high level of captain and first officer attrition during 2022 and 2023, which constrained our capacity to operate our major airline partners' requested flight schedules in full. During 2024, captain attrition began to ease and, by the end of 2025, we were operating full flight schedules requested by our major airline partners. Sequential fluctuations in the number of completed departures and completed block hours from 2023 to 2025 were primarily driven by available captains.

*Capacity and flight schedule impact.* We completed the following number of flights and related block hours in 2025, 2024 and 2023:

**Liquidity**

At December 31, 2025, we had $782.5 million in total available liquidity, consisting of $706.9 million in cash, cash equivalents and marketable securities, and $75.6 million available for borrowing under our line of credit.

**Industry Overview**

*Majors, Low-Cost Carriers and Regional Airlines*

The airline industry in the United States has traditionally been comprised of several major airlines, including Alaska, American, Delta and United. The major airlines offer scheduled flights to most major U.S. cities, numerous smaller U.S. cities, and cities throughout the world through a hub-and-spoke network.

Low-cost carriers, such as Southwest Airlines Co. ("Southwest"), JetBlue Airways Corporation ("JetBlue"), Spirit Airlines, Inc. ("Spirit"), Allegiant Travel Company ("Allegiant"), Frontier Group Holdings, Inc. ("Frontier") and Breeze Aviation Group, Inc. ("Breeze") generally have lower cost structures than major airlines, which permits them to offer flights to and from many of the same markets as the major airlines, but at lower prices. Low-cost carriers typically operate using a point-to-point network strategy, rather than a hub-and-spoke network.

Regional airlines, including SkyWest, typically operate smaller aircraft on shorter routes than major and low-cost carriers. Several regional airlines, including Endeavor, Envoy, Horizon, Piedmont and PSA, are wholly-owned subsidiaries of major airlines.

Regional airlines generally do not try to establish an independent route system and compete with the major airlines. Rather, regional airlines typically enter into agreements with one or more major airlines, pursuant to which the regional airline agrees to use its smaller, lower-cost aircraft to carry passengers booked and ticketed by the major airline between a hub of the major airline and a smaller outlying city. In exchange for such services, the major airline pays the regional airline either fixed fees to operate the flight, termed "capacity purchase agreement," or "flying contract," or the regional airline receives a percentage of applicable passenger ticket revenues on designated flights operated by the regional airline, termed "prorate agreement" as described in more detail below.

[**Table of Contents**](#Toc)

**Code-Share Agreements**

Regional airlines generally enter into code-share agreements with major airlines, pursuant to which the regional airline is authorized to use the major airline's two-letter flight designator codes to identify the regional airline's flights and fares in the central reservation systems, to paint its aircraft with the colors and/or logos of the major airline and to market and advertise its status as a carrier for the major airline. Code-share agreements also generally obligate the major airline to provide services such as reservations, ticketing, ground support and gate access to the regional airline, and the major airline often coordinates marketing, advertising and other promotional efforts. In exchange, the regional airline provides a designated number of low-capacity (usually between 50 and 76 seats) flights between larger airports served by the major airline and surrounding cities, usually in lower-volume markets. The financial arrangements between the regional airlines and their code-share partners usually involve either capacity purchase agreements or prorate agreements as explained below:

● *Capacity Purchase Agreements.* Under a capacity purchase agreement, the major airline generally pays the regional airline a fixed-fee for each departure, flight hour (measured from takeoff to landing, excluding taxi time) and block hour (measured from takeoff to landing, including taxi time) and an amount per aircraft in service each month with additional incentives based on completion of flights, on-time performance and other operating metrics. The regional airline typically acquires or finances the aircraft used under the capacity purchase agreement, which is accounted for as a lease of the aircraft to our major airline partner. In addition, under a capacity purchase agreement, the major airline bears the risk of fuel price fluctuations and certain other costs. Regional airlines benefit from capacity purchase agreements because they are protected from some of the elements that typically cause volatility in airline financial performance, including variations in ticket prices, number of passengers onboard each flight and changes in fuel prices. However, regional airlines with capacity purchase agreements generally do not benefit from positive trends in ticket prices, ancillary revenue, such as baggage and food and beverage fees, the number of passengers enplaned or decreasing fuel prices, because the major airlines retain passenger fare volatility risk and fuel costs associated with the regional airline flight.

● *Prorate Agreements.* Under a prorate agreement, the major airline and regional airline negotiate a passenger fare proration formula for specifically identified routes, pursuant to which the regional airline receives a percentage of the ticket revenues for those passengers traveling for one portion of their trip on the regional airline and the other portion of their trip on the major airline. On the other hand, the regional airline receives all of the passenger fare when a passenger purchases a ticket on a prorate route solely operated by the regional airline. Substantially all costs associated with the regional airline flight are borne by the regional airline, including the fuel cost. In a prorate agreement, the regional airline may realize increased profits as ticket prices and passengers carried increase or fuel prices decrease and, correspondingly, the regional airline may realize decreased profits as ticket prices and passengers carried decrease or fuel prices increase.

We have code-share agreements with United, Delta, American and Alaska. During the year ended December 31, 2025, approximately 84% of our flying agreements revenue related to capacity purchase agreement flights, where United, Delta, American and Alaska controlled scheduling, ticketing, pricing, and seat inventories. The remainder of our flying agreements revenue during the year ended December 31, 2025, related to prorate flights for United, Delta or American, where we controlled scheduling, pricing and seat inventories on certain prorate routes, and shared passenger fares with United, Delta or American according to prorate formulas and SWC on-demand charter flights. The routes placed under our prorate agreements typically include flight service between one of our partners' hub cities and a city not served under our capacity purchase agreements.

Under our capacity purchase agreements, our major airline partners compensate us for our costs of owning the aircraft on a monthly basis. The aircraft compensation structure varies by agreement but is intended to cover either our aircraft principal and interest debt service costs or our aircraft depreciation and interest expense while the aircraft is under contract. The number of aircraft under our capacity purchase agreements and our prorate agreements as of December 31, 2025 is reflected in the summary below. The following summaries of our code-share agreements with our major airline partners do not purport to be complete and are qualified in their entirety by reference to the applicable agreement.

\* Our prorate agreements are based on specific routes, not a specific aircraft count. The number of aircraft listed above for each prorate agreement approximates the number of aircraft we use to serve the prorate routes.

In addition to the aircraft operating under the respective agreements outlined above, we have agreed with our major airline partners to place additional aircraft under capacity purchase agreements as summarized below. We are coordinating with the aircraft manufacturer and our major airline partners regarding the timing of upcoming fleet deliveries. The anticipated deliveries and in-service timing referenced below are subject to change.

● Capacity purchase agreement with United for eight new E175 aircraft, which are scheduled for delivery in 2026. We anticipate financing the aircraft through debt.

● Capacity purchase agreement with Alaska for one new E175 aircraft, which is scheduled for delivery in 2026. We anticipate financing the aircraft through debt.

● Capacity purchase agreement with Delta for 16 new E175 aircraft. 10 new E175 aircraft are currently scheduled for delivery in 2027 and six new E175 aircraft are scheduled for delivery in 2028. The Company anticipates financing the aircraft through debt.

[**Table of Contents**](#Toc)

● Capacity purchase agreements with United for 23 used CRJ550 aircraft that are anticipated to be placed into service by the end of 2026. Pursuant to these agreements, the Company is in the process of converting its owned CRJ700s to CRJ550s.

In January 2026, we extended the scheduled contract expirations on 40 E175 aircraft with United and 13 E175 aircraft with Delta. The termination dates in the table above reflect the January 2026 extensions.

*United Express Agreements*

We and United are parties to two United Express capacity purchase agreements: a United Express agreement to operate certain CRJ700 aircraft, and a United Express agreement to operate E175 aircraft, CRJ550 aircraft and CRJ200 aircraft (collectively, the "United Express Agreements").

The United Express Agreements have a latest scheduled termination date of 2033. The United Express Agreements are subject to early termination in various circumstances including:

● if we or United fail to fulfill an obligation under the United Express Agreements, subject to applicable notice and cure periods;

● if our operations fall below certain performance levels or if we fail to meet certain safety standards;

● subject to limitations imposed by the U.S. Bankruptcy Code, if either party becomes insolvent, fails to pay its debts when due, takes action leading to its cessation as a going concern, makes an assignment of substantially all of its assets, or ceases or suspends operations; or

● subject to limitations imposed by the U.S. Bankruptcy Code, if bankruptcy proceedings are commenced by or against either party and certain specified conditions are not satisfied.

*Delta Connection Agreement*

We and Delta are parties to a Delta Connection capacity purchase agreement (the "Delta Connection Agreement"), pursuant to which we provide contract flight services for Delta.

The Delta Connection Agreement has a latest scheduled termination date of 2034. The Delta Connection Agreement is subject to early termination in various circumstances including:

● if we or Delta commit a material breach of the Delta Connection Agreement, subject to applicable notice and cure periods;

● if we fail to conduct all flight operations and maintain all aircraft under the Delta Connection Agreement in compliance in all material respects with applicable government regulations;

● if we fail to satisfy certain performance or safety requirements; or

● if either party files for bankruptcy, reorganization or similar action (subject to limitations imposed by the U.S. Bankruptcy Code) or makes an assignment for the benefit of creditors.

*American Agreement*

We and American are parties to a capacity purchase agreement (the "American Agreement") for the operation of E175 and CRJ700 aircraft. The American Agreement has a latest scheduled termination date of 2032 and is subject to early termination in various circumstances including:

● if we or American fail to fulfill certain obligations under the American Agreement, subject in certain cases to a 30-day notice and cure period;

● if our operations fall below certain performance levels or safety standards;

● subject to limitations imposed by the U.S. Bankruptcy Code, if either party makes a general assignment for the benefit of creditors or becomes insolvent; or

● subject to limitations imposed by the U.S. Bankruptcy Code, if bankruptcy proceedings are commenced by or against either party and certain specified conditions are not satisfied.

[**Table of Contents**](#Toc)

*Alaska Agreement*

We and Alaska are parties to a capacity purchase agreement (the "Alaska Agreement") for the operation of E175 aircraft. The Alaska Agreement has a latest scheduled termination date of 2034 and is subject to early termination in various circumstances including:

● if we or Alaska fail to fulfill an obligation under the Alaska Agreement, subject to applicable notice and cure periods;

● if our operational performance falls below certain performance levels or if we fail to satisfy certain safety requirements;

● subject to limitations imposed by the U.S. Bankruptcy Code, if either party makes a general assignment for the benefit of creditors or becomes insolvent; or

● subject to limitations imposed by the U.S. Bankruptcy Code, if bankruptcy proceedings are commenced by or against either party and certain specified conditions are not satisfied.

**Training and Aircraft Maintenance**

We provide substantially all training to our crew members and maintenance personnel at our training facilities. Our employees perform routine airframe and engine maintenance along with periodic inspections of equipment at our maintenance facilities. We also use third-party vendors for certain airframe and engine maintenance work.

**Fuel**

Our capacity purchase agreements with United, Delta, American and Alaska require the respective major airline partner to pay for fuel costs, either directly to the fuel vendor or to reimburse us for the fuel costs we incur under those agreements, thereby reducing our exposure to fuel price fluctuations. Under our prorate agreements with United, Delta and American, we are responsible for the costs to operate the flights, including fuel costs, and therefore we are exposed to fuel price fluctuations for flights operated under our prorate agreements. During the year ended December 31, 2025, our major airline partners purchased the majority of the fuel for our aircraft flying under their respective capacity purchase agreements directly from their fuel vendors or, when applicable, reimbursed us for the fuel costs we incurred under the capacity purchase agreements. Historically, we have not experienced sustained material problems with the availability of fuel and believe we will be able to obtain fuel in quantities sufficient to meet our existing and anticipated future requirements at competitive prices. We typically purchase fuel from third-party suppliers for our prorate agreements. A substantial increase in the price of jet fuel for flights we operate under our prorate agreements may have a material adverse effect on our financial results if we are unable to recover such cost increases through higher passenger fares. A substantial, prolonged shortage of fuel supply in the future, could have a material adverse effect on our business, financial condition, results of operations or liquidity.

**Human Capital Resources**

***Employee Profile***

As of December 31, 2025, we employed 15,775 total employees, consisting of 5,354 pilots, 4,831 flight attendants, 2,028 airport operations personnel, 1,728 maintenance technicians, 967 other maintenance personnel, 199 dispatchers and 668 operational support and administrative personnel. Our total employees at December 31, 2025, included 1,957 part-time employees. As of December 31, 2025, all our employees are employed by SkyWest Airlines or to a limited extent, by SWC. Certain SkyWest Airlines employees also provide administrative support to the SkyWest Leasing segment. Approximately 89.6% of these employees were represented by in-house labor associations that have entered into collective bargaining agreements regarding employee compensation and work rules. None of these employees are currently represented by an outside union. Outside union organizing efforts among our employees do occur from time to time and may continue in the future. If unionization efforts are successful, we may be subjected to increased risks of work interruption or stoppage; and/or we may be limited in our ability to communicate with our employees, which would negatively impact our culture and working relationship with our employees. Additionally, an outside union may limit our ability to increase employee wages to market rates in a timely manner which could result in low employee job satisfaction and increased employee attrition. SkyWest Airlines has never experienced a work stoppage due to a strike or other labor dispute, and we consider our relationships with our employees to be good.

[**Table of Contents**](#Toc)

Our relations with labor are governed by the Railway Labor Act (the "RLA"), the federal law governing labor relations between air carriers and their employees. Under the RLA, a collective bargaining agreement between an airline and a labor representative does not expire, but instead becomes amendable as of a stated date. If either party wishes to modify the terms of any such agreement, it must notify the other party in the manner prescribed by the RLA and/or described in the agreement. After receipt of such notice, the parties must meet for direct negotiations, and if no agreement is reached, either party may request the National Mediation Board ("NMB") to initiate a process including mediation, arbitration, and a potential "cooling off" period that must be followed before either party may engage in "self-help." "Self-help" includes, among other things, a strike by the representative or the imposition of proposed changes to the collective bargaining agreement by the airline. If the NMB believes that self-help has the risk "substantially to interrupt interstate commerce to a degree such as to deprive any section of the country of essential transportation service," it may recommend that the President establish a Presidential Emergency Board ("PEB"). The PEB would hear testimony and make a recommendation regarding how to resolve the outstanding issues.

We respect all employees' legal rights, including the rights to free association and collective bargaining. This includes the right to decide whether to be represented by a union. Under the RLA, employees have the right to decide whether they wish to be represented by a union. They also have the right to reject union representation.

***Culture***

At SkyWest our people are our most valued assets, and the success of our business is dependent on having a collaborative, engaged and effective workforce. We respect every individual's quality of life and are committed to promoting integrity and trust in all we do. We strive to be the partner of choice and employer of choice.

*Health & Safety*

Safety is the primary focus and foundation of our culture with our first guiding principle being Health and Safety First. We expect our employees to think, plan, communicate and act appropriately to prevent injury, illness or harm to themselves, fellow employees, passengers and aircraft. SkyWest's Safety Management System (SMS) integrates an intentional safety culture into every work group and every employee process from new hire through retirement, focusing on industry-best practices in safety competencies and behaviors. Safety training is required for every SkyWest employee annually, regardless of position.

SkyWest's SMS is designed to identify, track, and help mitigate potential safety risks before an incident or accident occurs. Employees are encouraged to participate in our voluntary programs to report potential safety concerns or violations to reduce safety risk, including, but not limited to our Aviation Safety Action Program and Safety Concern Report.

● Aviation Safety Action Program is a non-punitive program that allows employees in participating work groups to self-disclose violations of policies and procedures. Each report is reviewed by an Event Review Committee who helps identify any potential trends and determines whether corrective actions have been put into place to prevent the problem from occurring in the future.

● Safety Concern Reporting is a confidential program that allows all employees to identify potential safety risks within the operation. Each report is reviewed and investigated, as needed, by the Safety Department. Employees may also report safety concerns to their direct manager, the facility manager, a facility safety committee member or confidentially through our safety hotline.

*Attracting, Developing and Retaining Talent*

*Recruitment Strategies.* We strive to be the employer of choice for aviation professionals pursuing a career in the regional airline industry and we continually update our recruiting strategies to attract quality aviation professionals. We adapt our recruitment efforts based on the supply of eligible aviation professionals and our outlook for anticipated future flight schedules. Our recruiting focus generally targets key aviation technical roles, especially pilots and mechanics. We seek qualified individuals through publishing positions on both internal and external career websites, supporting professional development leads, investment in targeted advertising, social media outreach, employee referrals and relationships with community-based organizations and educational institutions. Through various interview and related programs with our major airline partners,

[**Table of Contents**](#Toc)

including United's Aviate program, our pilots have carrier pathway opportunities with our major airline partners.

*School Partnerships and Development.* We maintain relationships with numerous flight schools and educational institutions across the country that are focused on developing the next generation of aviation professionals. We have also developed relationships with numerous aviation mechanic schools. We typically recruit pilots and maintenance technicians that have completed required coursework from an accredited flight or maintenance school, respectively, and have obtained other applicable certifications. We also provide other programs to enhance our recruiting efforts towards individuals who are in process of completing their training, including a Pilot Pathway Program and an Aviation Maintenance Technician (AMT) Pathway Program.

● The SkyWest Pilot Pathway Program provides a direct path for qualified pilots seeking to begin their aviation career in the regional airline industry. Participants benefit from the SkyWest Pilot Pathway Program through certain starting seniority at SkyWest, final interview privileges and access to pilot mentors. The Pilot Pathway Program allows students to remain at their campus to complete their flight training until they meet SkyWest's Airline Transport Pilot standards and achieve their required minimum hours of flight time. Each participant may also participate in SkyWest recruiting events and outreach programs on their way to fulfilling commercial pilot jobs.

● The SkyWest AMT Pathway Program provides a career path for maintenance technicians seeking employment with SkyWest. Participants benefit from the SkyWest AMT Pathway Program through accelerated starting seniority at SkyWest, guaranteed final interview upon meeting requirements and access to mechanic advisors.

*Ongoing Training and Retention.* SkyWest invests in retaining its professionals by providing a range of talent development opportunities, including mandatory compliance training, new hire training and general professional development, as well as engaging in the training of leaders through leadership development courses. Our training programs include full-motion flight simulators for pilots, on-the-job training for technicians, and cabin trainers for flight attendants. We also reinforce our guiding principles, including but not limited to, health and safety, personal and corporate integrity, excellent service and quality, and respect and teamwork through our training and development programs, as well as through our employee appreciation and recognition programs.

*Total Rewards*

SkyWest Airlines operates in a customer-focused, team-based environment and provides opportunities for dedicated individuals to develop their career while receiving competitive compensation, benefits and rewards. Our employees receive several compensation benefits, including but not limited to:

● Competitive wages and incentives based on our operating performance goals,

● Multiple insurance options including health care, disability coverage and life insurance coverage,

● Access to a 401(k) plan with matching contributions and an employee stock purchase plan,

● Employee assistance programs that provide confidential counseling or psychiatric care,

● Free access to financial advisors for personal finance guidance and education,

● A variety of resources that promote scheduling flexibility with paid time away from work, and

● Space-available travel privilege programs for employees and eligible family members through our major airline partner programs.

*Employee Reporting*

Our Code of Conduct contains general guidelines for conducting business in an ethical manner. We are committed to a working environment that is safe and supports open and honest communication. We have established a reporting system for any SkyWest employee to report a violation of Company policy including harassment, discrimination, drug and alcohol use, questionable financial practice, or a breach involving safety or security. A general grievance may also be filed even if an employee has already utilized their chain of command or chooses to remain anonymous. Our Code of Conduct also forbids retaliation against any employee who, in good faith, reports a suspected

[**Table of Contents**](#Toc)

violation of law or policy. Reports can be filed with an independent service provider using a toll-free ethics and grievance hotline or by using an online reporting system accessible through SkyWest's intranet.

**Government Regulation**

All interstate air carriers, including SkyWest, are subject to regulation by the DOT, the U.S. Federal Aviation Administration (the "FAA") and other governmental agencies. Regulations promulgated by the DOT primarily relate to economic aspects of air service. The FAA requires operating, airworthiness and other certificates; approval of personnel who may engage in flight, maintenance or operating activities; record-keeping procedures in accordance with FAA requirements; and FAA approval of flight training and retraining programs. Generally, governmental agencies enforce their regulations through, among other methods, certifications, which are necessary for the continued operations of SkyWest, and proceedings, which can result in civil or criminal penalties or revocation of operating authority. The FAA can also issue maintenance directives and other mandatory orders relating to, among other things, grounding of aircraft, inspection of aircraft, installation of new safety-related items and the mandatory removal and replacement of aircraft parts.

We believe SkyWest complies, in all material respects, with FAA regulations and holds all operating and airworthiness certificates and licenses which are necessary to conduct our operations. We maintain current certifications and otherwise comply with the laws, rules and regulations to which we are subject. Our flight operations, maintenance programs, recordkeeping and training programs are conducted under FAA approved procedures. All air carriers operating in the United States are required to comply with federal laws and regulations pertaining to noise abatement and engine emissions. All such air carriers are also subject to certain provisions of the Federal Communications Act of 1934, as amended, because of their extensive use of radio and other communication facilities. SkyWest is also subject to certain federal and state laws relating to protection of the environment, labor relations and equal employment opportunity. We believe SkyWest complies, in all material respects, with these laws and regulations.

**Environmental Matters**

We are subject to various federal, state, local and foreign laws and regulations relating to environmental protection matters. These laws and regulations govern such matters as environmental reporting, storage and disposal of materials and chemicals and aircraft noise. We are, and expect in the future to be, involved in various environmental matters and conditions at, or related to, our properties. We are not currently subject to any environmental cleanup orders or actions imposed by regulatory authorities. We are not aware of any active material environmental investigations related to our assets or properties.

As the largest regional airline in the United States, we remain committed to working with our major airline partners to lower our environmental footprint while continuing to offer the best service to our customers and the communities we serve. Our largest source of emissions and environmental impact comes from utilizing jet fuel on flights operated under our code-share agreements with our major airline partners. Under our capacity purchase agreements, our major airline partners purchase the aircraft fuel we consume, select the aircraft type we operate, and set flight schedules, all of which are variables which impact fuel consumption efficiencies. During 2025, we produced approximately 6.3 million metric tons of CO<sub>2</sub>e from fuel burned, using industry emissions factors, on flights we operated under our code-share agreements. We are largely dependent on direction from our major airline partners regarding long-term fuel saving and carbon reducing initiatives such as engine innovations reducing fuel consumption, use of sustainable alternative fuels, carbon sequestration programs, air traffic flow routing efficiencies, and similar initiatives. Each of our major airline partners may pursue alternative strategies and goals to reduce carbon emissions on flights we operate under our code-share agreements that may impact the rate at which we are able to reduce our carbon emissions, if at all. We anticipate our major airline partners will take responsibility for carbon emissions incurred on our contract flights.

Our board of directors has oversight of our environment-related performance. Through software and training, we heavily monitor and manage our fuel trends and fuel consumption which leads to better fuel management and reductions in emissions. When possible, we conserve fuel burned by utilizing single engine taxi procedures, improving the efficiency of aircraft routing, using performance-based navigation procedures to reduce track miles, and using ground power when parked at the gate. Additionally, we collaborate with aircraft and engine manufacturers and our major airline partners regarding innovations and emerging technologies that could improve fuel efficiencies and minimize environmental impact. We are also collaborating with our major airline partners and fuel providers regarding long-term

[**Table of Contents**](#Toc)

opportunities to use sustainable aviation fuel in the future. We are evaluating opportunities to increase the number of electric powered ground equipment, including tugs and pushbacks used at airports where we provide ramp services. We participate with our major airline partners in recycling programs, and we have implemented recycling initiatives in our facilities to reduce the amount of paper, plastic and other recyclables going to landfills. We have worked aggressively to reduce our reliance on paper manuals, further eliminating unnecessary waste while increasing efficiencies.

We have entered into a strategic arrangement with Eve Holding, Inc. ("Eve", formerly EVE UAM, LLC, an Embraer company) to develop a network of deployment for Eve UAM's electric vertical takeoff and landing ("eVTOL") aircraft. Subject to an agreement of key commercial terms, this arrangement includes the option for SkyWest to purchase up to 100 eVTOL aircraft.

**Safety and Security**

We are committed to the safety and security of our passengers and employees. We have taken many steps, both voluntarily and as mandated by governmental authorities, to increase the safety and security of our operations. Some of the safety and security measures we have taken with our major airline partners include: aircraft security and surveillance, aircraft cleaning procedures, positive bag matching procedures, enhanced passenger and baggage screening and search procedures and securing of cockpit doors. We are committed to complying with future safety and security requirements.

**Insurance**

We maintain insurance policies we believe are of types customary in the industry and in amounts we believe are adequate to protect against material loss. These policies principally provide coverage for public liability, passenger liability, baggage and cargo liability, property damage, including coverage for loss or damage to our flight equipment, and workers' compensation insurance, and other coverages.

**Seasonality**

Our results of operations for any interim period are not necessarily indicative of those for the entire year, in part because the airline industry is subject to seasonal fluctuations and changes in general economic conditions. Our operations are somewhat favorably affected by leisure travel on our prorate routes, historically contributing to increased travel in the summer months, and are unfavorably affected by decreased business travel during the months from November through January and by inclement weather which can result in cancelled flights, principally during the winter months. Additionally, a significant portion of our capacity purchase agreements are based on completing flights and we typically have more scheduled flights during the summer months. We generally experience a significantly higher number of weather cancellations during the winter months, which negatively impacts our revenue during such months.

**Additional Information**

**ITEM 1A. RISK FACTORS**

*In addition to factors discussed elsewhere in this Report, the following are important risks which could adversely affect our future results. Additional risks and uncertainties not presently known to us or that we currently do not deem material may also impair our business operations. If any of the risks we describe below occur, or if any* 

[**Table of Contents**](#Toc)

*unforeseen risk develops, our operating results may suffer, our financial condition may deteriorate, the trading price of our common stock may decline and investors could lose all or part of their investment in us.*

**Risks That May Disrupt Our Operations**

***Various negative economic or industry conditions may result in reductions to our flight schedules, which could materially and adversely affect our operations and financial condition.***

Our operations and financial condition are affected by many changing economic and other conditions beyond our control, including, among others:

● actual or potential changes in international, national, regional and local economic, business and financial conditions, including recession, inflation, higher interest rates, higher taxes and/or tariffs, public health emergencies, including pandemics, wars (including the ongoing conflict between Russia and Ukraine, Israel and Hamas, and Israel and Iran), terrorist attacks or political instability;

● impact on workforce availability and economic uncertainty;

● future public health threats, outbreaks of diseases or other illnesses could negatively affect travel behavior and the industry;

● changes in consumer preferences, perceptions, spending patterns or demographic trends;

● changes in the competitive environment due to industry consolidation, new airlines entering the market, our major airline partners operating smaller sized aircraft that may reduce the demand for regional aircraft and other factors;

● actual or potential disruptions to U.S. air traffic control systems, caused by a government funding shutdown or otherwise;

● interference on aviation equipment from the deployment of 5G wireless telecommunications systems, or other factors disrupting communications;

● price of jet fuel and oil that may negatively impact the number of flights we are scheduled to operate by our major airline partners under our capacity purchase agreements and may negatively impact the profitability of our prorate agreements;

● disruptions in the credit markets, which may impact availability of price competitive financing;

● weather and natural disasters.

The effect of any, or some combination, of the foregoing economic and industry conditions on our operations or financial condition is virtually impossible to forecast; however, the occurrence of any or all of such conditions in a significant manner could materially and adversely affect our operations and financial condition and could cause our major airline partners to reduce the utilization levels of our aircraft under our code-share agreements.

***We may experience disruption in service due to delays from key third-party service providers.***

We rely on third-party service providers to supply aircraft parts and for a variety of services and other functions critical to our business, particularly related to airframe and engine maintenance and repair. A service failure by one of our key service providers could result in a disruption to our operations. We use third party service providers in several areas including, but not limited to, aircraft maintenance, ground handling, fueling, telecommunication systems and information technology services. Current economic conditions have resulted in delays from third-party service providers for spare aircraft parts, and third-party service providers have recently experienced challenges in retaining trained technicians. Delays from third-party service providers could negatively impact our ability to timely maintain our fleet currently in service. Additionally, we plan to continue bringing certain CRJ aircraft out of storage and placing such aircraft into service. Delays in receiving spare parts and/or outsourced maintenance services could delay our efforts to place stored aircraft back into service.

Further, in the event that one or more vendors experiences labor shortages, aircraft part shortages, seeks bankruptcy protection, ceases operation or fails to perform as promised, replacement services may not be readily available at competitive rates, or at all. If one of our vendors fails to perform adequately, we may experience increased costs, delays, maintenance issues, safety issues or negative public perception of our airline. Vendor bankruptcies, unionization, regulatory compliance issues or significant changes in the competitive marketplace among suppliers could

[**Table of Contents**](#Toc)

adversely affect vendor services or force us to renegotiate existing agreements on less favorable terms. These events could result in disruptions in our operations or increases in our cost structure.

***Cybersecurity incidents, hardware or software failures or other information technology disruptions may negatively impact our operations, reputation and financial condition.***

The performance and reliability of our technology are critical to our ability to compete effectively. Any internal technological error, failure or large-scale external interruption in the information systems, networks, hardware, software and technological infrastructure we depend on, such as U.S. air traffic control systems, power, telecommunications or the internet (collectively, "IT Systems"), may disrupt our internal network, impact our ability to conduct our business and result in lower revenue and/or increased costs. Our IT Systems (including those provided by third parties) and information about our employees and other individuals and proprietary information belonging to our business such as trade secrets ("Confidential Information") are vulnerable to a variety of sources of interruption due to events beyond our control, including natural disasters, terrorist attacks, telecommunications or IT System failures, computer viruses, hackers and other security issues.

In addition, we face numerous and evolving cybersecurity risks that threaten the security, confidentiality, integrity and availability of our IT Systems and Confidential Information, including from diverse threat actors such as state-sponsored organizations, opportunistic hackers and hacktivists, as well as through diverse attack vectors, such as social engineering/phishing, security breaches, malfeasance by insiders, human or technological error, computer viruses, malicious or destructive code, misconfigurations, "bugs" or other vulnerabilities in commercial software that is integrated into our (or our service providers') IT Systems, products or services, malware (including ransomware) and other attacks, including through fraud or other means of deception. The methods used to obtain unauthorized access, disable or degrade service or attack or sabotage systems are constantly evolving, and threat actors are becoming increasingly sophisticated in using techniques and tools – including artificial intelligence – that circumvent security controls, evade detection and remove forensic evidence. As a result we may be unable to anticipate or to detect, investigate, remediate or recover from attacks or incidents for long periods of time. Further, we may not be able to prevent all data breaches, misuses of data (including Confidential Information) or other cybersecurity incidents.

There can also be no assurance that our cybersecurity risk management program and processes, including our policies, controls or procedures, will be fully implemented, complied with or effective in protecting our IT Systems and Confidential Information. Because we rely on third-party vendors and service providers for functions critical to our business, including information technology infrastructure and services, successful cyberattacks that disrupt or result in unauthorized access to third-party IT Systems can materially impact our operations and financial results. Remote and hybrid working arrangements at our company (and at many third-party service providers) also increase cybersecurity risks due to the challenges associated with managing remote computing assets and security vulnerabilities that are present in many non-corporate and home networks. Additionally, any integration of artificial intelligence into our operations, products or services, or those of our third party vendors, service providers or airline partners, is expected to pose new or unknown cybersecurity risks and challenges.

We and certain of our third-party service providers have in the past experienced cybersecurity incidents. We expect such incidents to continue in varying degrees and cannot assure our cybersecurity risk management program will prevent such incidents from occurring in the future. While no incidents have had a material impact on our operations or financial results to date, we cannot guarantee that material incidents will not occur in the future as further described in "Item 1C. Cybersecurity". Although we previously carried cybersecurity insurance coverage in the past, we currently do not have cybersecurity insurance coverage. Any cybersecurity incident or other adverse impact to the availability, integrity or confidentiality of our IT Systems or Confidential Information could compromise our ability to operate flights or technology systems, result in the loss of Confidential Information, legal claims or proceedings (such as class actions), regulatory investigations and enforcement actions, liability or regulatory penalties, disruption to our operations, damage to our reputation, loss of existing or future customers and/or significant incident response, system restoration or remediation and future compliance costs. Any or all of the foregoing could adversely affect our business, results of operations and financial condition.

***Interruptions or disruptions in service at one of our hub airports, due to weather, system malfunctions or for any other reason, could have a material adverse impact on our operations.***

We currently operate primarily through hubs supporting our major airline partners' route networks across the United States. Nearly all of our flights either originate from or fly into one of these hubs. Our revenues depend primarily on our completion of flights and secondarily on service factors such as timeliness of departure and arrival. Any interruptions or disruptions could, therefore, severely and adversely affect us. Extreme weather such as hurricanes or tornados can cause flight disruptions, and, during periods of storms or adverse weather, our flights may be canceled or significantly delayed. We operate a significant number of flights to and from airports with potential winter related or other weather difficulties, including but not limited to, Chicago, Dallas, Denver, Detroit, Houston, Minneapolis, Salt Lake City and San Francisco. A significant interruption or disruption in service at one of our hubs, due to adverse weather, system malfunctions, air traffic control disruptions, airport construction, security closures, protests or otherwise, could result in the cancellation or delay of a significant portion of our flights and, as a result, could have a severe adverse impact on our operations and financial performance.

***We may experience difficulty in recruiting, training and retaining a sufficient number of qualified pilots.***

Our operations rely on recruiting and training qualified pilots. FAA regulations regarding personnel certification and qualifications have limited and, along with potential future changes in FAA regulations, could continue to limit the number of qualified new entrants that we could hire. In the event we are unable to recruit and train a sufficient number of qualified pilots, we may be unable to operate requested flight schedules under our capacity purchase agreements, which could result in a reduction in revenue and operating inefficiencies, such as incremental new-hire training costs, and our business and financial condition could be adversely affected.

Our operations also rely on retaining qualified pilots, including captains and first officers. Our pilots may seek employment at major airlines, low-cost carriers or cargo carriers, which generally offer higher salaries and more extensive benefit programs than regional airlines. A shortage of captains caused a sequential reduction in our annual block hours in 2022 and 2023. Although captain attrition levels eased in 2024 and we were operating full flight schedules requested by our major airline partners by the end 2025, future elevated pilot attrition levels could constrain our flight schedules. Operating at reduced flying schedules results in operating inefficiencies which negatively impacts our financial results. If we request our major airline partners to reduce our flight schedules due to pilot or other labor shortages, our major airline partners may seek to enforce financial penalties or reduce the compensation otherwise payable to us under our capacity purchase agreements, which would likely have a negative impact on our revenues and adversely impact our financial condition.

***We have experienced, and may continue to experience, difficulty recruiting and retaining other operational personnel.***

In addition to pilots, our operations rely on recruiting and retaining other qualified personnel, including, but not limited to, flight attendants, maintenance technicians, dispatch personnel, crew support and other operational personnel. Our operational personnel may seek employment at major airlines, which generally offer higher salaries and more extensive benefit programs than regional airlines. Additionally, alternative career opportunities in other industries, developments in artificial intelligence or other macroeconomic factors could increase our attrition and/or negatively impact our ability to recruit new employees. Should the attrition of our employees sharply increase, we may not be able to hire sufficient personnel to replace those leaving. In the event we are unable to hire and retain other qualified personnel, we may be unable to operate requested flight schedules under our capacity purchase agreements, which could result in a reduction in revenue and operating inefficiencies, such as incremental new-hire training costs, and our business and financial condition could be adversely affected.

***The occurrence of an aviation accident involving our aircraft would negatively impact our operations and financial condition.***

An accident or incident involving one of our aircraft could result in significant potential claims of injured passengers and others, as well as repair or replacement of a damaged aircraft and its consequential temporary or permanent loss from service. In the event of an accident, our liability insurance may not be adequate to offset our exposure to potential claims and we may be forced to bear substantial losses from the accident. Substantial claims resulting from an accident in excess of our related insurance coverage would harm our operational and financial results. Moreover, any aircraft accident or incident, even if fully insured, could cause a public perception that our operations are

[**Table of Contents**](#Toc)

less safe or reliable than other airlines and could affect our relationships with our major airline partners. In addition, any accident or incident involving a type of aircraft in our fleet could result in air travelers being reluctant to fly on our aircraft, and adversely impact our business, results of operations and financial condition.

***We are subject to significant governmental regulation and potential regulatory changes.***

All interstate air carriers, including SkyWest, are subject to regulation by the DOT, the FAA and other governmental agencies. Regulations promulgated by the DOT primarily relate to economic aspects of air service. The FAA requires operating, air worthiness and other certificates; approval of personnel who may engage in flight, maintenance or operation activities; recordkeeping procedures in accordance with FAA requirements; and FAA approval of flight training and retraining programs. We cannot predict whether we will be able to comply with all present and future laws, rules, regulations and certification requirements or that the cost of continued compliance will not have a material adverse effect on our operations. We incur substantial costs in maintaining our current certifications and otherwise complying with the laws, rules and regulations to which we are subject. A decision by the FAA to ground, or require time-consuming inspections of or maintenance on, all or any of our aircraft for any reason may have a material adverse effect on our operations. In addition to state and federal regulation, airports and municipalities enact rules and regulations that affect our operations. From time to time, various airports throughout the country have considered limiting the use of smaller aircraft, such as our aircraft, at such airports. The imposition of any limits on the use of our aircraft at any airport at which we operate could have a material adverse effect on our operations.

We cannot predict the impact of potential regulatory changes that may affect our business or the airline industry as whole, including the potential impact of tariffs on aircraft deliveries. However, it is possible that these changes could adversely affect our business. Our business may be subject to additional costs or loss of government subsidies as a result of potential regulatory changes, which could have an adverse effect on our operations and financial results.

***Changes to U.S. tariff and import/export regulations may have a negative effect on our suppliers and/or service providers and, in turn, could have a material adverse impact on our financial condition.***

The United States has recently enacted significant tariffs in excess of historical levels, and United States trade policies continue to evolve. Accordingly, there continues to exist significant uncertainty about the future relationship between the United States and other countries with respect to such trade policies, treaties and tariffs. These developments, or the perception that any of them could occur, may have a material adverse effect on global economic conditions and the stability of global financial markets. The recently enacted tariffs have had a significant impact on the cost of aircraft parts and supplies sourced internationally, including but not limited to, the non-U.S. manufactured components used on the E175 aircraft we import from Brazil. These added costs negatively impact us.

***Compliance, or failure to comply, with new or existing laws, regulations and other requirements relating to the privacy, security and handling of information about individuals could adversely affect our business, results of operations, or financial condition.***

We receive information related to employees and other individuals in order to run our business. Laws, regulations and other requirements relating to the privacy, security and handling of information about individuals, alongside the application and interpretation of such requirements, are constantly evolving and developing and subject to change, creating a complex compliance environment. There has been heightened legislative and regulatory focus on data privacy and security in the United States and elsewhere, including in relation to cybersecurity incidents, and it is possible that new laws, amendments to or interpretations of existing laws, regulations and other requirements may require us to incur significant costs, implement new processes or change our handling of information and business operations. In addition, any failure or perceived failure by us to comply with laws, regulations and other requirements relating to the privacy, security and handling of information could result in legal claims or proceedings (including class actions), regulatory investigations or enforcement actions. We could incur significant costs in investigating and defending such claims and, if found liable, pay significant damages or fines or be required to make changes to our business. Further, these proceedings and any subsequent adverse outcomes may subject us to significant negative publicity and an erosion of trust. If any of these events were to occur, our business, results of operations, and financial condition could be materially adversely affected.

***Terrorist activities or warnings have dramatically impacted the airline industry and will likely continue to do so.***

Past terrorist attacks and their aftermath have negatively impacted the airline industry in general, including our operations. If additional terrorist attacks are launched against the airline industry, there will be lasting consequences of such attacks, which may include loss of life, property damage, increased security and insurance costs, increased concerns about future terrorist attacks, increased government regulation and airport delays due to heightened security. Additionally, terrorist attacks and the fear of such attacks could negatively impact the airline industry, and result in decreased passenger traffic and yields, increased flight delays or cancellations associated with new government mandates, as well as increased security, fuel and other costs. We cannot provide any assurance that these events will not harm the airline industry generally or our operations or financial condition in particular.

**Risks Related to Our Code-Share Agreements with Our Major Airline Partners**

***Our business model is dependent on code-share agreements with four major airline partners.***

Our business model depends on major airlines electing to contract with us instead of operating their own aircraft or regional jets. Some regional airlines are owned by a major airline. We have no guarantee that in the future our major airline partners will choose to enter into contracts with us instead of operating their own aircraft or regional jets or award more flying contracts to another regional airline. Our major airline partners are not prohibited from doing so under our code-share agreements. A decision by any of our major airline partners to phase out code-share relationships and instead acquire and operate their own regional jets or regional airline, or award more flying contracts to another regional airline, could have a material adverse effect on our financial results. Additionally, our major airline partners may be limited in the number of regional aircraft they can operate in their network due to aircraft scope limitations they have with their labor groups. Scope limitations could limit our ability to increase the number of aircraft operating under our code-share agreements.

As of December 31, 2025, 353 out of our total 487 aircraft in scheduled service were operating under a capacity purchase agreement or a prorate agreement with either United or Delta. If our code-share relationship with United or Delta were terminated, our operations would be significantly impacted and we would not likely have an immediate source of revenue or earnings to offset such loss. A termination of either of these relationships would likely have a material adverse effect on our financial condition, operating revenues and net income unless we are able to enter into satisfactory substitute arrangements for the utilization of the affected aircraft by other code-share partners, or, alternatively, obtain the airport facilities and gates and make the other arrangements necessary to fly as an independent airline. We may not be able to enter into substitute code-share agreements, and any such arrangements we might secure may not be as favorable to us as our current agreements. Operating SkyWest Airlines as an airline independent from our major airline partners would be a significant departure from our business plan and would likely require significant time and resources and may not be a viable alternative.

Additionally, each of our agreements with our major airline partners is subject to certain early termination provisions, including uncured material performance breaches. We also currently use the systems, facilities and services of our major airline partners to support a significant portion of our operations, including airport and terminal facilities and operations, information technology support, ticketing and reservations, scheduling, dispatching, fuel purchasing and ground handling services. If our major airline partners cease to maintain any of these systems, close any of these facilities or no longer provide these services to us, due to termination of one of our code-share agreements, a strike or other labor interruption by personnel working for our major airline partners or for any other reason, we may not be able to obtain alternative systems, facilities or services on terms and conditions as favorable as those we currently receive, or at all. Since our revenues and operating profits are dependent on our level of flight operations, we could then be forced to significantly reduce our operations.

***Reduced utilization levels of our aircraft under our capacity purchase agreements with our major airline partners would have a material adverse impact on the results of our operations and financial condition.***

Under our capacity purchase agreements with our major airline partners, a portion of our compensation is based on pre-determined rates that are applied to our production, such as block hours, for the period. We also receive fixed monthly payments related to overhead costs and aircraft ownership costs from our major airline partners. Reduced utilization of our aircraft under our capacity purchase agreements will likely have a material adverse impact on the results of our operations and financial condition. In recent years, compensation under our capacity purchase agreements

[**Table of Contents**](#Toc)

with certain major airline partners have a lower percentage of contractual fixed monthly payments and a higher percentage of contractual variable payments. A compensation structure that is weighted more to utilization and less to fixed payments could have a material adverse impact on the results of our operations and financial condition if utilization levels decrease. Additionally, amendments to our capacity purchase agreements that result in changes to our future scheduled fixed monthly payments will likely impact the timing of our revenue recognition. During the year ended December 31, 2025, the revenue we recognized was $57.8 million more than the fixed monthly cash payments received. As of December 31, 2025, we have received a cumulative total of $264.6 million in fixed monthly cash payments that we have not recognized as revenue. Although we currently anticipate we will recognize previously deferred revenue for the year ending December 31, 2026, future contract amendments or reduced utilization levels of our aircraft could negatively impact the timing of our revenue recognition.

***Our major airline partners may experience events that negatively impact their financial strength or operations, which may also negatively impact our operations.***

Our business model relies significantly on our major airline partners, and we may be negatively affected by their financial and operating strength. Events impacting airline travel, including pandemics or recessions, that negatively impact the financial strength of our major airline partners or have a long-term effect on the use of our major airline partners by airline travelers would likely have a material adverse effect on our business, financial condition and results of operations. If our major airline partners experience adverse effects to their operational or financial condition, they may be unable to make payments due to us under their capacity purchase agreements or may need to reduce utilization of our aircraft. Additionally, if one of our major airline partners undergoes bankruptcy, our agreement with such partner may not be assumed in bankruptcy and could be terminated. This and other events, which are outside of our control, could have a material adverse effect on our business, financial condition and results of operations.

***Our growth may be limited with our major airline partners' flight systems.***

Additional growth opportunities within our major airline partners' flight systems are limited by various factors, including a limited number of regional aircraft each major airline partner can operate in its regional network due to scope limitations in its own labor agreements. Except as contemplated by our existing code-share agreements, we cannot be sure that our major airline partners will contract with us to fly any additional aircraft. We may not receive additional growth opportunities, or we may agree to modifications to our code-share agreements at less favorable terms in order to obtain additional aircraft, or for other reasons. Certain of our competitor regional airlines may agree to flying contract terms at lower rates or unfavorable contract terms, which could affect the terms offered to us. Even if we are offered growth opportunities by our major airline partners, those opportunities may involve economic terms or financing commitments that are unacceptable to us. Additionally, our major airline partners may reduce the number of regional jets in their system by not renewing or extending existing flying agreements with regional operators. Any one or more of these factors may reduce or eliminate our ability to expand our flight operations with our existing major airline partners.

***There are long-term risks related to supply and demand of regional aircraft associated with our regional airline services strategy.***

Various factors could change our major airline partners' long-term strategy in using regional aircraft to support their network objectives. Such changes could result in a reduction in the number of regional aircraft our major airline partners operate in the future. If our major airline partners' future strategies include a material reduction in regional aircraft generally or for specific aircraft types that we operate, the resulting decrease in demand in the aircraft we operate could have a material negative impact on our business and financial condition. Additionally, future developments of electric-powered aircraft designed to operate on routes typically served by regional aircraft could impact our major airline partners' strategy and result in a reduction of demand or increase our capital expenditures and could have a material negative impact on our business and financial condition.

Due, in part, to the dynamic nature of the airline industry, major airlines may also make other strategic changes, such as changing or consolidating hub locations or operating mainline aircraft on routes previously served using regional aircraft. If our major airline partners were to make changes such as these in their strategy and operations, our operations and financial results could be adversely impacted.

[**Table of Contents**](#Toc)

***Revenue levels from our prorate agreements with our major airline partners may not continue to increase and are terminable upon notice of 180 days or less. Additionally, revenue levels from our SWC operation may not continue to increase.***

While our prorate agreements and SWC revenue increased $153.0 million, or 33.5%, for the year ended December 31, 2025, compared to the year ended December 31, 2024, there is no assurance our prorate revenue or SWC revenue will continue to increase in 2026 or thereafter. Future increases in prorate revenue is based on several factors subject to change including, but not limited to, passenger demand on prorate routes, approval of new routes with our major airline partners, maintenance required to return parked aircraft for service and labor availability. Additionally, there is no assurance we will continue to be awarded subsidy contracts under the EAS program on applicable prorate routes from the DOT going forward. Additionally, there is no assurance the EAS program will continue to receive funding by the U.S. Government. Future increases in SWC revenue is also based on several factors subject to change including, but not limited to, corporate or institutional demand for charter flights, competition for charter business and availability of other charter alternatives, such as ground transportation. SWC was granted commuter authority from the DOT in 2025, allowing SWC to expand its route strategy. There is no assurance that SWC will be awarded EAS markets or other commuter routes in the future, nor that demand for its services will materialize as anticipated.

Our prorate flying agreements with our major airline partners permit each major airline partner to terminate the agreement in its discretion by giving us notice of 180 days or less. If one of our major airline partners elects to terminate a flying agreement with notice of 180 days or less, our ability to use the aircraft under an alternative agreement with similar economics may be limited, which could negatively impact our financial results. Additionally, even if we could subsequently place the aircraft into service with a different major airline partner, of which there can be no assurance, we likely would incur inefficiencies and incremental costs, such as changing the aircraft livery, during the transition period, which would negatively impact our financial results.

***Disagreements regarding the interpretation of our code-share agreements with our major airline partners could have an adverse effect on our operating results and financial condition.***

Long-term contractual agreements, such as our code-share agreements, are subject to interpretation and disputes may arise under such agreements if the parties to an agreement apply different interpretations to that agreement. Those disputes may divert management's time and resources from the core operation of the business, and may result in litigation, arbitration or other forms of dispute resolution.

We have previously experienced disagreements with our major airline partners regarding the interpretation of various provisions of our code-share agreements. Some of those disagreements have resulted in litigation, and we may be subject to additional disputes and litigation in the future. Furthermore, there can be no assurance that any or all future disputes and related proceedings, if commenced, would be resolved in our favor. An unfavorable result in any such proceeding could have adverse financial consequences or require us to modify our operations. Such disagreements and their consequences could have an adverse effect on our relationship with our major airline partners, operating results and financial condition.

***We operate on-demand charter flights through our wholly-owned subsidiary, SWC, and such operations involve significant risk.***

SWC offers on-demand charter service using CRJ200 aircraft in a 30 seat configuration under its own FAA operating certificate. As we pursue growth opportunities with SWC, there may be significant risks, including that SWC may divert management's attention or the Company's resources from our core business and strategies. Additionally, the anticipated objectives of SWC, such as those associated with its recent DOT approval to operate under commuter authority, may not materialize or may take longer to materialize than anticipated.

***The airline industry is highly competitive, which could adversely affect our operating results and financial condition.***

The airline industry is highly competitive. We compete with other regional airlines on various factors including, but not limited to, labor resources, including pilots and mechanics; low operating costs; financial resources, including the ability to finance aircraft at competitive terms; geographical infrastructure; and overall customer service levels relating to on-time arrival and flight completion percentages. Our major airline partners rely on us to fly passengers from various locations into their hubs under our code-share agreements at competitive terms. We not only compete with other regional

[**Table of Contents**](#Toc)

airlines, some of which are owned by or operated as code-share partners of major airlines, but we also indirectly face competition from low-cost carriers, such as Southwest, Allegiant, Spirit, JetBlue, Breeze and others, who compete with our major airline partners on many routes we operate. Certain of our competitors, including wholly-owned regional airline subsidiaries of our major airline partners, may have access to significantly greater financial and other resources than we do. Moreover, federal deregulation of the industry allows competitors to rapidly enter our markets and to quickly discount and restructure fares. The inability to remain competitive on the various factors valued by our major airline partners could adversely affect our operating results and financial condition.

**Risks Related to Our Operating Costs and Personnel**

***Increases in labor costs, including pilot costs, flight attendant costs, maintenance costs and overhead costs may result in lower operating margins under our capacity purchase agreements.***

Under our capacity purchase agreements with our major airline partners, a portion of our compensation is based upon pre-determined rates typically applied to production statistics (such as departures, block hours, flight hours and number of aircraft in service each month). The primary operating costs intended to be compensated by the pre-determined rates include our labor and training costs, aircraft maintenance expenses and overhead costs. During the year ended December 31, 2025, approximately 93.0% of our code-share operating costs were reimbursable at pre-determined rates and 7.0% of our code-share operating costs were directly reimbursed costs, often referred to as pass-through costs. Our business is labor intensive, requiring large numbers of pilots, flight attendants, mechanics and other personnel. Labor costs constitute a significant percentage of our total operating costs. Increases in our labor costs could result in a material reduction in our earnings. For example, during the years ended December 31, 2025 and 2024, our salary, wage and benefit costs constituted approximately 45.3% and 48.3% of our total operating costs, respectively. Various factors may cause us to significantly increase compensation to our labor groups, such as higher compensation offered by other airlines or other factors impacting the labor market in the United States. Our inability to offset increased labor costs through rate increases under our capacity purchase agreements with all our major airline partners could negatively impact our operating profitability. Currently, we believe our labor costs are competitive relative to other regional airlines. However, we cannot provide assurance that our labor costs going forward will remain competitive because of changes in supply and demand for labor in the regional airline industry. We compete against other airlines and businesses for labor in many highly skilled positions. If we are unable to hire, train and retain qualified employees at a reasonable cost, sustain employee engagement in our strategic vision, or if we are unsuccessful at implementing succession plans for our key staff, we may be unable to grow or sustain our business. Labor costs to recruit, incentivize and retain skilled employees may significantly increase in the future due to increased competition for the limited number of qualified industry personnel. Attrition rates that exceed our ability to hire and replace applicable workgroups could negatively impact our ability to generate revenue, negatively impact our operating results, increase our training and labor costs and our business prospects could be harmed.

Additionally, our aircraft maintenance costs may increase annually as our fleet ages at a higher rate than our pre-determined rates in our capacity purchase agreements. Also, on an individual aircraft basis, various in-depth maintenance procedures are typically scheduled to occur at multi-year intervals, which can result in maintenance expense fluctuations year-to-year. If our operating costs for labor, aircraft maintenance and overhead costs exceed the compensation earned from our pre-determined rates under our capacity purchase agreements, our financial position and operating results will be negatively affected.

***Increased labor costs, pilot and other labor availability, labor disputes and unionization of our workforces may adversely affect our ability to conduct our business and reduce our profitability.***

Any new labor agreement entered into by other regional carriers with their work forces may result in higher industry wages and increase pressure on us to increase the wages and benefits of our employees. If our labor agreements become uncompetitive with respect to employee compensation or work rules, we may experience higher employee attrition and low employee job satisfaction, which may negatively impact our operating and financial results.

Our employees are represented by in-house associations; however, organizing efforts to join national unions among those employees occur from time to time. Such efforts will likely continue in the future and may ultimately result in some or all of our employees being represented by one or more national unions. If our employees were to unionize or be deemed to be represented by one or more national unions, negotiations with these unions could divert management's

[**Table of Contents**](#Toc)

attention and disrupt operations. Additionally, representation by a national union may limit our ability to have open communications with our employees, negatively impact our company culture and deter our ability to amend and increase our compensation packages for market conditions in a timely manner, which may result in higher employee dissatisfaction and attrition. Moreover, we cannot predict the outcome of any future negotiations relating to union representation or collective bargaining agreements. A national union soliciting to represent our employees may represent employees at mainline carriers or other regional airlines and may have conflicting interests with those of our employees or SkyWest. Future collective bargaining agreements involving a national union and our employees may negatively impact our relationship with our employees and have an adverse impact on our operating and financial results.

***We may experience an increase in fuel prices in our prorate and SWC operations.***

Dependence on foreign imports of crude oil, limited refining capacity and the possibility of changes in government policy on jet fuel production, transportation and marketing make it difficult to predict the future availability of jet fuel. If there are additional outbreaks of hostilities or other conflicts in oil-producing areas or elsewhere, or a reduction in refining capacity (due to weather events, for example), or governmental limits on the production or sale of jet fuel, there could be a reduction in the supply of jet fuel and significant increases in the cost of jet fuel. Additionally, our operations may experience disruptions from temporary fuel shortages by our fuel vendors resulting from fuel quality issues, refueling disruption or other challenges. Major reductions in the availability of jet fuel or significant increases in its cost, or a continuation of high fuel prices for a significant period of time, would have a material adverse impact on us.

Pursuant to our capacity purchase agreements, our major airline partners have agreed to bear the economic risk of fuel price fluctuations on our contracted flights. However, we bear the economic risk of fuel price fluctuations on our prorate and SWC operations. As of December 31, 2025, we operated 28 CRJ200s under a prorate agreement with United, 14 CRJ550s under a prorate agreement with Delta and 10 CRJ900s under a prorate agreement with American. As of December 31, 2025, we had 11 CRJ200s available for on-demand charter service through SWC. Our operating and financial results with respect to these prorate agreements and charter services can be negatively affected by the price of jet fuel in the event we are unable to increase our passenger fares. Additionally, in the event of prolonged low fuel prices, our competitors may lower their passenger ticket prices on routes that compete with our prorate or charter markets, which could negatively impact our prorate and charter revenue.

***Our business could be harmed if we lose the services of our key personnel.***

Our business depends upon the efforts of our president and chief executive officer, Russell A. Childs, and our other key management and operating personnel. We may have difficulty replacing management or other key personnel who cease to be employed by us and, therefore, the loss of the services of any of these individuals could harm our business. We do not maintain key-person insurance on any of our executive officers.

***We may experience credit losses in excess of our estimated credit loss reserves.***

Our financial results include estimated credit loss reserves associated with our accounts receivables, notes receivables and third-party debt guarantees. Our actual credit losses may exceed our estimated allowances, for a number of factors including but not limited to, counterparties' bankruptcy, undervalued collateral and/or inability to liquidate collateral, which could negatively impact our financial condition and financial results.

***We have guaranteed the indebtedness of third parties that may default on their debt and require us to pay.***

In 2022, we agreed to guarantee debt for a commuter air carrier that operates smaller aircraft than we operate. The debt is secured by the air carrier's aircraft and engines and has a five-year term. At December 31, 2025, the outstanding debt for the guarantee was $12.6 million. The purpose of this arrangement is to increase the potential number of commercial pilots in our hiring pipeline, particularly for commercial pilots who are interested in progressing their career and operating larger regional aircraft at SkyWest Airlines. In the event of default, if we are unable to sell the collateral, or the fair value is less than the required payment, it could negatively impact our financial condition and financial results. Additionally, there is no guarantee that the relationship with this entity will have a favorable effect on our ability to recruit pilots.

**Risks Related to Operating and Leasing Regional Jet Aircraft and Engines**

***We are reliant on two aircraft manufacturers and one engine manufacturer.***

We operate aircraft manufactured by Bombardier and Embraer. The issuance of FAA or manufacturer directives restricting or prohibiting the use of any Bombardier or Embraer aircraft types we operate could negatively impact our business and financial results. We are also dependent upon General Electric as the sole manufacturer of engines used on the aircraft we operate. Our operations could be materially and adversely affected by the failure or inability of Bombardier, Embraer, General Electric or other certified replacement part companies to provide sufficient parts or related maintenance and support services to us on a timely manner. Additionally, timing and availability of new aircraft deliveries could be delayed beyond our control.

***We have a significant amount of contractual long-term debt obligations.***

As of December 31, 2025, we had a total of approximately $2.4 billion in total long-term debt obligations. Our long-term debt obligations included $2.2 billion of debt used to finance aircraft and spare engines and $200.6 million related to borrowings under the Payroll Support Program Agreements with U.S. Department of the Treasury ("Treasury"). Various changes in airline industry and macroeconomic or other conditions could negatively impact our ability to obtain additional financing to support additional expansion plans or divert cash flows from operations and expansion plans to service the fixed obligations.

Under our capacity purchase agreements, our major airline partners compensate us for our costs of owning the aircraft on a monthly basis. The aircraft compensation structure varies by agreement but is intended to compensate us for using our aircraft while under contract. In the event any of our major airline partners defaults under a capacity purchase agreement or we are unable to extend the flying contract terms on aircraft that we have ongoing financial obligations for, our financial position and financial results could be materially adversely affected.

In addition, we may seek material amounts of additional financial liquidity in the short-term, which may include drawing down on SkyWest Airlines' line of credit, the issuance of secured debt securities and/or the entry into other debt facilities, among other financial instruments. There can be no assurance as to the timing of any such drawdown or issuance, which may be in the near term, or that any such additional financing will be completed on favorable terms, or at all.

If our liquidity is materially diminished, we might not be able to timely pay our debt or other obligations or comply with certain covenants under SkyWest Airlines' line of credit or with other material provisions of our contractual obligations.

***We expect to issue debt to finance our anticipated aircraft purchases.***

As of December 31, 2025, we have firm purchase commitments for 69 E175 aircraft and spare engines totaling $2.3 billion. Over the next several years, as we continue to add new aircraft to our fleet, we anticipate using significant amounts of capital to acquire these aircraft.

There can be no assurance that our operations will generate sufficient cash flow or liquidity to enable us to obtain the necessary aircraft acquisition financing to replace our current fleet, or to make required debt service payments related to our existing or anticipated future obligations. Even if we meet all required debt and other financial obligations, the amount of our long-term obligations could negatively affect our financial condition and results of operations in many ways, including:

● increasing the cost, or limiting the availability of, additional financing for working capital, acquisitions or other purposes;

● limiting the ways in which we can use our cash flow, much of which may have to be used to satisfy debt and lease obligations; and

● adversely affecting our ability to respond to changing business or economic conditions or continue our growth strategy.

If we need additional capital and cannot obtain such capital on acceptable terms, or at all, we may be unable to realize our fleet replacement plans or take advantage of unanticipated opportunities.

[**Table of Contents**](#Toc)

***The residual value of our owned aircraft may be less than estimated in our depreciation policies.***

As of December 31, 2025, we had approximately $5.8 billion of property and equipment and related assets, net of accumulated depreciation. In accounting for these long-lived assets, we make estimates about the expected useful lives of the assets, the expected residual values of certain of these assets, and the potential for impairment based on the fair value of the assets and the cash flows they generate. Factors indicating potential impairment include, but are not limited to, amendments to our capacity purchase agreements that impact the anticipated cash flows for our aircraft, significant decreases in the market value of the long-lived assets, a significant change in the condition of the long-lived assets and operating cash flow losses associated with the use of the long-lived assets. In the event the estimated fair value of any of our aircraft types is determined to be lower than the net book value of the applicable aircraft type, such aircraft type in our fleet may be impaired and may result in a material impairment charge. An impairment on any of our aircraft types we operate or an increased level of depreciation expense resulting from a change to our depreciation policy and assumptions could result in a material negative impact to our financial results. Future decisions to sell specific aircraft could potentially result in write-downs for aircraft held-for sale.

***We lease aircraft and engines to third parties and the lessee may default under the lease terms, which could negatively affect our financial condition, cash flow and results of operations.***

We leased five CRJ900 aircraft, 40 CRJ700/CRJ550 aircraft, and several CRJ aircraft engines to third parties as of December 31, 2025. In the event a lessee defaults under the terms of the lease agreement, we may incur additional costs, including legal and other expenses necessary to repossess the aircraft or engines, particularly if the lessee is contesting the proceedings or is in bankruptcy. We could also incur substantial maintenance, refurbishment or repair costs if a defaulting lessee fails to pay such costs and where such maintenance, refurbishment or repairs are necessary to put the aircraft or engines in suitable condition for remarketing or sale. We may also incur storage costs associated with any aircraft or engine that we repossess and are unable to place immediately with another lessee. Even if we are able to immediately place a repossessed aircraft or engine into service ourselves, or place the aircraft and engines under another lessee, we may not be able to do so at a similar or favorable lease rate. A lessee default under one of our lease agreements could negatively affect our financial condition, cash flow and results of operations.

***We have entered into a strategic engine leasing joint venture that operates under joint control with a third party that may not meet our investment objectives.***

We have entered into a strategic engine joint venture with a third party to lease engines to other parties. This strategic venture involves investment risks, including:

● we may not realize a satisfactory return on our investment;

● the joint venture may divert management's attention from our core business;

● our joint venture partner could have investment goals that are not consistent with our investment objectives, including the timing, terms and strategies for any investments; and

● our joint venture partner might fail to fund their share of required capital contributions or fail to fulfill their other obligations.

Although we currently participate in the management of our engine joint venture, our joint venture agreement requires unanimous approval over all significant actions. In addition, if we were unable to resolve a dispute with our joint venture partner that retains material managerial veto rights, we might reach an impasse that could require us to dissolve the joint venture at a time and in a manner that could negatively affect our financial results.

***We entered into an arrangement with a third party to develop demand for electric-powered aircraft that involves significant uncertainty and risk.***

We have entered into a strategic arrangement with Eve to develop a network of deployment for Eve's eVTOL aircraft. To support this effort, SkyWest may provide assistance to Eve on vehicle design, vertiport specifications and the certification roadmap for eVTOL operations. This strategic arrangement involves significant uncertainty risks, including:

● development and certification of the aircraft is uncertain or may take longer than expected;

● future customer demand for eVTOL aircraft is uncertain;

● other parties are developing electric-powered aircraft and the level of competition may increase;

[**Table of Contents**](#Toc)

● the extent government regulation of eVTOL aircraft and its related infrastructure is uncertain, and the cost of compliance with any such regulations may be significant;

● we may not realize a satisfactory return on our investment; and

● our partner might fail to fulfill its obligations.

The effect of any, or some combination, of the foregoing risks could affect our arrangement with Eve and future benefits may not materialize.

As of December 31, 2025, we held 1.1 million shares of common stock of Eve (NYSE: EVEX). At December 31, 2025, the fair value of our holdings in Eve was $4.3 million and there is no assurance the value of Eve common stock will increase.

***We have invested in Contour, which involves significant risk and may not produce a satisfactory return on our investment.***

As of December 31, 2025, we have invested $25.0 million in Contour, a 14 CFR Part 135 air carrier. This strategic investment involves significant risks, including:

● we may not realize a satisfactory return on our investment;

● the investment may divert management's attention from our core business; and

● Contour could have operational or financial goals that are not consistent with our investment objectives, including the strategies and objectives for increasing value for Contour's shareholders.

The effect of any, or some combination, of the foregoing risks could negatively affect our financial results.

***We are subject to various environmental requirements, including laws and regulations related to climate change and emissions. Compliance with new or existing environmental requirements could materially and adversely affect the Company's business plans, strategies and results of operations.***

We are subject to federal, state and local laws and regulations relating to the protection of the environment, including those relating to aircraft and ground-based emissions, discharges into water systems, safe drinking water and the management of hazardous substances and waste materials. Certain legislative bodies and regulatory authorities are increasingly focused on climate change and have taken actions to implement additional laws, regulations and programs intended to protect the environment and may require specific reporting requirements. For example, the federal government, as well as several state and local governments, have implemented legislative and regulatory proposals and voluntary measures intended to reduce greenhouse gas emissions. Compliance with laws, regulations and other programs intended to reduce emissions or otherwise protect the environment may require us to reduce our emissions, secure carbon offset credits or otherwise pay for emissions, or make capital investments to modify certain aspects of our operations to reduce emissions. Future policy, legal and regulatory developments relating to the protection of the environment could increase our costs and have a material adverse effect on our operations.

***We support our major airline partners' goals and strategies to reduce carbon emissions on flights we operate under our code-share agreements and, as we work to support each of our major airline partners' goals and strategies, initiatives to reduce emissions may not materialize and could materially and adversely affect the Company's business plans, strategies and results of operations.***

During 2025, we produced approximately 6.3 million metric tons of CO<sub>2</sub>e primarily from jet fuel emissions, using industry emissions factors for jet fuel gallons consumed on flights we operated under our code-share agreements. Under our flying contracts, our major airline partners are responsible for fuel procurement and selection of the type of aircraft we operate and have significant control over our flight schedules. Accordingly, we anticipate our major airline partners will take responsibility for carbon emissions incurred on our contract flights. Each of our major airline partners may have different goals, strategies and timelines to reduce carbon emissions on our flights. We are largely dependent on the direction from our major airline partners regarding long-term fuel saving initiatives such as engine innovations reducing fuel consumption, use of sustainable alternative fuels, carbon sequestration programs, air traffic flow routing efficiencies, among other initiatives. Each of our major airline partners may pursue alternative strategies and goals to reduce carbon emissions on flights we operate under our code-share agreements that may impact the rate at which we are able to reduce our carbon emissions, if at all. There is no assurance our major airline partners will take responsibility for

[**Table of Contents**](#Toc)

carbon emissions incurred under our contract flights and no assurance future long-term fuel saving initiatives will materialize. In the event we pursue initiatives to reduce our carbon emissions, the cost could materially and adversely affect our business plans and results of operations.

**Risks Related to Dividends, Share Repurchases and Our Common Stock**

***We cannot assure that we will resume dividend payments in the future and we cannot assure that we will continue stock repurchases in the future.***

Historically, we have paid dividends and repurchased shares of our common stock in varying amounts. From April 2020 through September 30, 2022, we were restricted from paying dividends and repurchasing shares of our common stock under three Payroll Support Program Agreements and under a loan agreement with Treasury. During 2023, we resumed repurchasing shares of our common stock. We have not paid a dividend since 2020.

There can be no assurance that we will resume our past practice of paying dividends on our common stock or that we will have the financial resources to pay such dividends. The future payment of dividends will depend upon our financial condition, alternative uses of the Company's cash and results of operations and other factors deemed relevant by our board of directors.

In May 2023, our board of directors approved a share repurchase program, pursuant to which we are authorized to repurchase up to $250 million of our common stock and in May 2025, the Board approved a $250 million increase to the existing stock repurchase program. Under our repurchase program we are authorized to repurchase such shares of common stock at prevailing market prices in the open market, in privately negotiated transactions or by other means in accordance with federal securities laws. Depending on market conditions and other factors, such repurchases may commence or be suspended from time to time by management without prior notice. The actual timing, number and value of shares repurchased will be determined by our management in its discretion. The number of shares of common stock that we may repurchase, including pursuant to the share repurchase program, will depend upon our financial condition and results of operations and other factors deemed relevant by our board of directors. There also can be no assurance that we will continue repurchasing shares of common stock under our current authorization, that our board of directors will approve additional share repurchase programs in the future or that we will have the financial resources to repurchase shares of common stock in the future.

Repurchases of our common stock pursuant to our share repurchase program and any future dividends could affect our stock price and increase its volatility. Additionally, our share repurchase program and any future dividends may reduce our cash reserves, which may impact our ability to finance future growth and to pursue possible future strategic opportunities and acquisitions.

***Our common stock price may fluctuate significantly.***

Volatility in our common stock price may prevent holders from selling shares at or above the prices paid for them. During the year ended December 31, 2025, our common stock closing price varied between a high of $123.72 and a low of $79.41. The market price of our common stock may fluctuate significantly for a variety of reasons, including, but not limited to: general market, political and other economic conditions; labor availability, including regional airline pilots; new regulatory pronouncements or changes in regulatory guidelines; announcements concerning the airline industry, our major airline partners or competitors; the market's reaction to our quarterly or annual earnings or those of other companies in the airline industry; failure to meet financial analysts' performance expectations or changes in recommendations by financial analysts for our common stock or the stock of other airlines; significant sales of our common stock, and other risks described in these "Risk Factors." In recent periods, the stock market has experienced extreme volatility, significantly impacting the market price of securities issued by many companies, including us and other companies in our industry.

***Provisions of our articles of incorporation, by-laws and code-share agreements may limit the ability or desire of others to gain control of our Company.***

Our ability to issue shares of preferred and common stock without shareholder approval may have the effect of delaying or preventing a change in control and may adversely affect the voting and other rights of the holders of our common stock, even in circumstances where such a change in control would be viewed as desirable by most investors.

[**Table of Contents**](#Toc)

The provisions of the Utah Control Shares Acquisitions Act or other related regulations and laws may also discourage the acquisition of a significant interest in or control of our Company. Additionally, our code-share agreements contain termination and extension trigger provisions related to change in control type transactions that may have the effect of deterring a change in control of our Company.

**General Risk Factors**

***We may be a party to litigation in the normal course of business or otherwise, which could affect our financial condition and results of operations.***

We may become party to or otherwise involved in legal proceedings, claims and government inspections or investigations and other legal matters, arising in the ordinary course of our business or otherwise, including, but not limited to those related to injury or tort, environmental, employment and commercial legal issues. Legal proceedings can be complex and take many months, or even years, to reach resolution, with the final outcome depending on a number of variables, some of which are not within our control. Litigation is subject to significant uncertainty and may be expensive, time-consuming and disruptive to our operations. Although we will vigorously defend ourselves in such legal proceedings, their ultimate resolution and potential financial and other impacts on us are uncertain. If a legal proceeding is resolved against us, it could result in significant compensatory damages or injunctive relief that could materially adversely affect our financial condition, results of operations and cash flows.

***The adoption of new tax legislation or changes to existing tax laws and regulations could adversely affect our financial condition or results of operations.***

We are subject to tax laws and regulations of the U.S. federal, state and local governments as well as various non-U.S. jurisdictions. Potential changes in existing tax laws, including future regulatory guidance, may impact our effective tax rate and tax payments. There can be no assurance that changes in tax laws or regulations, both within the United States and the other jurisdictions in which we operate, will not materially and adversely affect our effective tax rate, tax payments, financial condition and results of operations. Similarly, changes in tax laws and regulations that impact our major airline partners, customers or the economy generally may also impact our financial condition and results of operations.

In addition, tax laws and regulations are complex and subject to varying interpretations, and any significant failure to comply with applicable tax laws and regulations in all relevant jurisdictions could give rise to substantial penalties and liabilities. Any changes in enacted tax laws, rules or regulatory or judicial interpretations; any adverse outcome in connection with tax audits in any jurisdiction; or any change in the pronouncements relating to accounting for income taxes could materially and adversely impact our effective tax rate, tax payments, financial condition and results of operations.

**ITEM 1C. CYBERSECURITY**

**Cybersecurity Risk Management and Strategy** 

Our approach to mitigating information technology and cybersecurity risk comprises a range of activities with the primary objective of maintaining the confidentiality, integrity and availability of our critical IT Systems and information related to our business. Although IT Systems are inherently vulnerable to interruption due to a variety of sources, we have aligned our cybersecurity risk management program, including our processes and controls, with certain applicable and relevant guidelines. For example, we have aligned our processes with the National Institute of Standards and Technology Cybersecurity Framework (NIST CSF) and assess our cybersecurity maturity against the NIST CSF's core functions; however, this does not imply that we meet any particular technical standards, specifications or requirements, only that we use the NIST CSF as a guide to help us identify, assess and manage cybersecurity risks relevant to our business.

Our cybersecurity risk management processes include a cybersecurity incident response plan, and we have invested in technical and organizational safeguards intended to manage and mitigate material risks from cybersecurity

[**Table of Contents**](#Toc)

threats to our IT Systems, including network security controls, employee training, internal vetting of third-party vendors and service providers with whom we may share data, and regular system reviews and security exercises. Our cybersecurity risk management program is a component of our overall enterprise risk management program, and shares common methodologies, reporting channels and governance processes that apply across the enterprise risk management program to other legal, compliance, strategic, operational, and financial risk areas.

While we work closely with accredited third-party cybersecurity firms, where appropriate, to audit our security architecture, our Information Security Team, consisting of experienced cybersecurity professionals, is responsible for the day-to-day management of our cybersecurity risks, including directing our cybersecurity risk assessment processes, our security processes, and our response to cybersecurity incidents.

For the year ended December 31, 2025, we have not identified risks from known cybersecurity threats, including as a result of any prior cybersecurity incidents, that have or are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial condition. We face certain ongoing risks from cybersecurity threats that, if realized, are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial condition. See "Risk Factors – Cybersecurity incidents, hardware or software failures or other information technology disruptions may negatively impact our operations, reputation and financial condition."

**Cybersecurity Governance**

Our Board considers cybersecurity risk as critical to the enterprise and delegates the cybersecurity risk oversight function to the Audit Committee. The Audit Committee oversees management's design, implementation and enforcement of our cybersecurity risk management program.

Our Board and our Audit Committee receive quarterly reports from management on our cybersecurity risks. In addition, management updates the Audit Committee, as necessary, regarding cybersecurity incidents it considers to be significant or potentially significant. Audit Committee members also receive presentations on cybersecurity topics from our Vice President of Information Technology and Chief Financial Officer, supported by our internal security staff, or external experts as part of the Board's continuing education on topics that impact public companies and update the full Board as necessary.

Our management team, including our Chief Financial Officer and Vice President of Information Technology, is responsible for assessing and managing our material risks from cybersecurity threats. The team has primary responsibility for leading our overall cybersecurity risk management program and supervises both our internal cybersecurity personnel and our external cybersecurity service providers. Our Vice President of Information Technology has more than 25 years of experience managing and leading IT and cybersecurity teams. Our Vice President of Information Technology participates in the Aviation ISAC organization, an international membership community of airframers, airlines, airports, satellite manufacturers, aviation services, and their supply chains that collaborate to prevent, detect, respond to, and remediate cyber risk through threat intelligence sharing and best practices.

Our management team takes steps to stay informed about and monitor efforts to prevent, detect, mitigate, and remediate cybersecurity risks and incidents through various means, which may include briefings from internal security personnel, threat intelligence and other information obtained from governmental, public or private sources, including external consultants engaged by us, and alerts and reports produced by security tools deployed in the IT environment.

| CRJ200s | 58 |  | 50 | 1500 | 530 | 22.8 |

---

Several factors may impact our fleet size throughout 2026 and thereafter, including, but not limited to, contract expirations that are not renewed, labor shortages, reductions in our prorate fleet, lease expirations on aircraft with our major airline partners that are not extended and growth opportunities. Our actual future fleet size and/or mix of aircraft types and future aircraft scheduled utilization will likely vary, and may vary materially, from our current fleet size and/or mix and aircraft utilization. The number of leased aircraft in the table above are aircraft we lease from our major airline partners for a de minimis monthly cost under capacity purchase agreements (also referred to as partner-financed aircraft).

**Ground Facilities**

We lease many of the buildings and associated land that we occupy. Most of these leases are for facilities at airports with various government agencies that control the use of the airport. We lease maintenance, training and office facilities in Salt Lake City, Utah, and we lease additional maintenance facilities in Boise, Idaho; Fresno, California; Chicago, Illinois; Detroit, Michigan; Nashville, Tennessee; South Bend, Indiana; Lincoln, Nebraska; Omaha, Nebraska; Shreveport, Louisiana; and Palm Springs, California. We also lease ticket counters, passenger hold rooms, operating areas and other terminal space in many of the airports that we serve.

We own our corporate headquarters facilities located in St. George, Utah and a maintenance accessory shop facility in Salt Lake City, Utah. We also own maintenance facilities on land leases with airport authorities in Milwaukee, Wisconsin; Oklahoma City, Oklahoma; Colorado Springs, Colorado; and Tucson, Arizona.

**ITEM 3. LEGAL PROCEEDINGS**

We are subject to certain legal actions which we consider routine to our business activities. As of December 31, 2025, our management believed, after consultation with legal counsel, that the ultimate outcome of such legal matters was not likely to have a material adverse effect on our financial position, liquidity or results of operations. However, the ultimate resolution of these matters is inherently uncertain.

**Overview**

We have the largest regional airline operation in the United States through our operating subsidiary SkyWest Airlines. As of December 31, 2025, we offered scheduled passenger and air freight service with approximately 2,260 total daily departures to destinations in the United States, Canada and Mexico. Our fleet of E175, CRJ900, CRJ700 and

[**Table of Contents**](#Toc)

CRJ550 have a multiple-class seat configuration, whereas our CRJ200 have a single-class seat configuration. During 2022, we formed SWC, which offers on-demand charter services using CRJ200 aircraft in a 30-seat configuration. As of December 31, 2025, we had 637 total aircraft in our fleet, including 487 aircraft in scheduled service or under contract pursuant to our code-share agreements, summarized as follows:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
|  | **E175** | **CRJ900** | **CRJ700/CRJ550** | **CRJ200** | **Total** |
| United | 121 |  | 37 | 58 | 216 |
| Delta | 87 | 32 | 18 |  | 137 |
| American | 20 | 4 | 68 |  | 92 |
| Alaska | 42 |  |  |  | 42 |
| &nbsp;&nbsp;Aircraft in scheduled service or under contract | 270 | 36 | 123 | 58 | 487 |
| SWC |  |  |  | 11 | 11 |
| Leased to third parties |  | 5 | 40 |  | 45 |
| Other <sup>(1)</sup> |  | 10 | 15 | 69 | 94 |
| &nbsp;&nbsp;Total Fleet | 270 | 51 | 178 | 138 | 637 |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) As of December 31, 2025, other aircraft included: supplemental spare aircraft supporting our code-share agreements that may be placed under future code-share or leasing agreements, aircraft scheduled to be placed under a code-share agreement with one of our major airline partners or aircraft that are scheduled to be disassembled for use as spare parts.

Our business model is based on providing scheduled regional airline service under code-share agreements (commercial agreements between airlines that, among other things, allow one airline to use another airline's flight designator codes on its flights) with our major airline partners. In exchange for such services, our major airline partners pay us either fixed fees to operate the flight, referred to as "capacity purchase agreement," or we receive a percentage of applicable passenger ticket revenues on the designated flights we operate, referred to as "prorate agreement." Our success is principally centered on our ability to meet the needs of our major airline partners by providing a reliable and safe operation at attractive economics. During the year ended December 31, 2025, we made changes to our fleet, including the addition of seven new E175 aircraft and one partner-financed E175 aircraft.

We anticipate our fleet will continue to evolve, as we are scheduled to add a total of eight new E175 aircraft with United in 2026, 16 new aircraft with Delta between 2027 and 2028 (which are expected to replace 12 CRJ900s and four CRJ700s we are currently flying under contract with Delta) and one new E175 aircraft with Alaska in 2026. We also have multiple agreements with United to place 23 used CRJ550 aircraft into service in 2026. Timing of placing these additional aircraft into service, including delivery timing on acquired aircraft, may be subject to change as we are coordinating with our major airline partners in response to labor availability or other factors. Our primary objective in the fleet changes is to improve our profitability by adding new E175 aircraft and used CRJ700, CRJ550, CRJ900 and E175 aircraft, commonly referred to as "dual-class aircraft" due to the first-class seat offerings, to our capacity purchase agreements or prorate agreements, and potentially removing older aircraft from service that typically require higher maintenance costs.

For the year ended December 31, 2025, approximately 44.4% of our aircraft in scheduled service or under contract were operated for United, approximately 28.1% were operated for Delta, approximately 18.9% were operated for American and approximately 8.6% were operated for Alaska.

Historically, multiple contractual relationships with major airlines have enabled us to reduce our reliance on any single major airline code and to enhance and stabilize operating results through a mix of our capacity purchase agreements and our prorate agreements. For the year ended December 31, 2025, our capacity purchase revenue represented approximately 84.3% of our total flying agreements revenue and our prorate and SWC revenue, combined, represented approximately 15.7% of our total flying agreements revenue. On capacity purchase routes, the major airline partner controls scheduling, ticketing, pricing and seat inventories and we are compensated by the major airline partner at contracted rates based on completed block hours (measured from takeoff to landing, including taxi time), flight departures, the number of aircraft under contract and other operating measures. We control scheduling, pricing and seat inventories on certain prorate routes, and we share passenger fares with our major airline partners according to prorate formulas. We are also responsible for the operating costs of the prorate flights, including fuel and airport costs.

**Financial Highlights**

We had total operating revenues of $4.1 billion for the year ended December 31, 2025, a 15.0% increase compared to total operating revenues of $3.5 billion for the year ended December 31, 2024. We had net income of $428.3 million, or $10.35 per diluted share, for the year ended December 31, 2025, compared to net income of $323.0 million, or $7.77 per diluted share, for the year ended December 31, 2024. The significant items affecting our revenue and operating expenses during the year ended December 31, 2025, are outlined below:

*Revenue*

The number of aircraft we have in scheduled service or under contract pursuant to our code-share agreements and the number of block hours we incur on our flights are primary drivers of our flying agreements revenue under our capacity purchase agreements. The number of flights we operate and the corresponding number of passengers we carry are the primary drivers of our revenue under our prorate agreements. The number of aircraft we have in scheduled service or under contract pursuant to our code-share agreements decreased from 492 as of December 31, 2024, to 487 as of December 31, 2025, or by 1.0%; and the number of block hours increased from 1.3 million in 2024 to 1.5 million in 2025, or by 14.7%, primarily due to an increase in the scheduled daily utilization of our aircraft driven by an increase in the number of available captains.

Our capacity purchase revenue increased $319.3 million, or 10.8%, from 2024 to 2025, primarily as a result of an increase in completed block hours for the comparable periods. As a result of a higher number of passengers carried on our prorate routes and an increase in the number of prorate and charter flights operated year-over-year, our prorate and SWC revenue increased $153.0 million, or 33.5%, in 2025, as compared to 2024.

*Operating Expenses* 

Our total operating expenses increased $407.1 million, or 13.4%, for the year ended December 31, 2025, compared to the year ended December 31, 2024. The increase in operating expenses was primarily due to an increase in our direct operating expenses associated with the increase in the number of flights we operated for the year ended December 31, 2025, compared to the year ended December 31, 2024. Departures increased from 766,742 for the year ended December 31, 2024 to 863,513 for the year ended December 31, 2025, or by 12.6%, and our total block hours increased 14.7% in 2025, as compared to 2024. Additional details regarding the increase in our operating expenses are described in the section of this Report entitled "Results of Operations."

*Fleet Activity*

The following table summarizes our fleet in service or under contract as of December 31, 2024 and December 31, 2025:

During 2025, we took delivery of seven new E175 aircraft and placed the aircraft into service under capacity purchase agreements, and we placed one partner-financed E175 aircraft into service under a capacity purchase agreement. We placed 18 SkyWest owned CRJ550 aircraft into service under a capacity purchase agreement or prorate agreement, while removing 14 CRJ700 aircraft from flying agreements. We placed four SkyWest owned CRJ900 aircraft into service under a prorate agreement while removing four partner-financed CRJ900 aircraft from flying agreements. We also removed 17 CRJ200 aircraft from service during 2025. We are evaluating alternative uses for the CRJ200 aircraft removed from service.

*Operational Statistics*

The following table sets forth our major operational statistics and the associated percentage changes for the periods identified below. The increase in block hours, departures and passengers carried during the year ended December 31, 2025, compared to the year ended December 31, 2024, was primarily due to an increase in the number of block hours incurred per aircraft as the number of available captains did not significantly limit our flight schedules during 2025, compared to 2024, which allowed for a higher scheduled utilization of our aircraft.

Flying agreements revenue primarily consists of revenue earned on flights we operate under our capacity purchase agreements and prorate agreements with our major airline partners and on-demand charter flights. Lease, airport services and other revenues consist of revenue earned from leasing aircraft and spare engines to third parties separate from our capacity purchase agreements, providing maintenance services to other airlines and providing airport counter, gate and ramp services.

We disaggregate our flying agreements revenue into the following categories (dollar amounts in thousands):

The increase in "Capacity purchase agreements flight operations revenue" of $175.1 million, or 7.3%, for the year ended December 31, 2025, compared to the year ended December 31, 2024, was primarily due to a 14.7% year-over-year increase in block hour production from aircraft under our capacity purchase agreements, offset by a capacity purchase agreement contract extension in 2025 that decreased the allocation of certain fixed monthly revenue from flight

[**Table of Contents**](#Toc)

operations revenue and increased the allocation of such payments to aircraft lease revenue based on relative standalone selling prices of the lease and non-lease components for the year ended December 31, 2025.

Under our capacity purchase agreements, we are paid a fixed amount per month per aircraft over the contract term. We recognize the total projected fixed monthly payments per aircraft as revenue proportionately to the number of block hours we complete for each reporting period, relative to the estimated number of block hours we anticipate completing over the remaining contract term. Under our capacity purchase agreements, the performance obligation of each completed flight is measured in block hours incurred for each completed flight. Based on the number of completed block hours during the year ended December 31, 2025, we recognized a total of $38.3 million of previously deferred revenue and unbilled revenue related to the non-lease fixed monthly payments we received associated with our flight operations revenues. For the year ended December 31, 2024, we recognized a total of $43.4 million of previously deferred revenue and unbilled revenue related to non-lease fixed monthly payments received associated with our flight operations revenues. The timing of our revenue recognition related to the fixed payments associated with our flight operations will be adjusted over the remaining contract term for each capacity purchase agreement based on the number of block hours we complete each reporting period relative to the number of block hours we anticipate completing over the remaining contract term of each capacity purchase agreement.

The increase in "Capacity purchase agreements aircraft lease revenue" of $144.2 million, or 26.7%, for the year ended December 31, 2025, compared to the year ended December 31, 2024, was primarily driven by a change in the mix of aircraft under our capacity purchase agreements from the year ended December 31, 2024 and a capacity purchase agreement contract extension in 2025 that decreased the allocation of certain fixed monthly revenue from flight operations revenue and increased the allocation of such payments to aircraft lease revenue based on relative standalone selling prices of the lease and non-lease components for the year ended December 31, 2025. Under our capacity purchase agreements, a portion of the consideration we are paid is designed as reimbursement for certain aircraft ownership costs and is considered lease revenue, including fixed monthly payments and variable payments. We recognize the fixed monthly lease payments as lease revenue using the straight-line basis over the capacity purchase agreement term and variable lease payments are recognized in the period when the block hours are completed. Additionally, we recognized a total of $19.5 million of previously deferred lease revenue and unbilled revenue during the year ended December 31, 2025, using the straight-line basis for fixed monthly lease payments, compared to recognizing a total of $1.5 million of previously deferred revenue and unbilled revenue during the year ended December 31, 2024.

The deferred revenue balance applicable to each contract will be recorded as revenue over the term of each respective contract. For clarity, under our "Capacity purchase agreements flight operations revenue" and "Capacity purchase agreements aircraft lease revenue" combined, we recognized a total of $57.8 million of previously deferred revenue and unbilled revenue during the year ended December 31, 2025, compared to recognizing a total of $44.9 million of previously deferred revenue and unbilled revenue during the year ended December 31, 2024. Our total deferred revenue balance, associated with our "Capacity purchase agreements flight operations revenue" and our "Capacity purchase agreements aircraft lease revenue," net of unbilled revenue, was $264.6 million as of December 31, 2025, compared to total deferred revenue, net of unbilled revenue of $322.4 million as of December 31, 2024.

The increase in prorate agreements and SWC revenue of $153.0 million, or 33.5%, for the year ended December 31, 2025, compared to the year ended December 31, 2024, was primarily due to an increase in prorate departures, passengers and passenger revenue we received on routes we operated under our prorate agreements driven by an improvement in the number of available captains during the year ended December 31, 2025, compared to the year ended December 31, 2024.

The increase in lease, airport services and other revenues of $57.9 million, or 50.3%, for the year ended December 31, 2025, compared to the year ended December 31, 2024, was primarily due to an increase in maintenance services provided to third parties, an increase in the number of leased assets, and increase in lease rates during 2025 compared to 2024.

---

*Salaries, wages and benefits.* The $95.4 million, or 6.5%, increase in salaries, wages and benefits for the year ended December 31, 2025, compared to the year ended December 31, 2024, was primarily due to an increase in direct labor costs that resulted from the higher number of flights we operated, partially offset by operating efficiencies from higher utilization of our aircraft during the year ended December 31, 2025, compared to the year ended December 31, 2024.

*Aircraft maintenance, materials and repairs.* The $231.1 million, or 32.4%, increase in aircraft maintenance expense for the year ended December 31, 2025, compared to the year ended December 31, 2024, was primarily due to incremental maintenance costs incurred on our CRJ fleet, an increase in our flight volume, which increased our maintenance activity and related expenses, and an increase in maintenance service activities provided to third parties for the year ended December 31, 2025, compared to the year ended December 31, 2024.

*Depreciation and amortization.* The $19.4 million, or 5.0%, decrease in depreciation and amortization expense for the year ended December 31, 2025, compared to the year ended December 31, 2024, was primarily due to certain fixed assets that became fully depreciated during 2024 and as a result of extending the estimated useful lives on our CRJ700/CRJ550 fleet by an average of three years and revising the residual values of the assets accordingly during the fourth quarter of 2024, which had a full year effect in 2025, partially offset by an increase in depreciation expense related to the acquisition of seven new E175 aircraft and spare engines since December 31, 2024.

*Airport-related expenses.* Airport-related expenses include airport-related customer service costs such as outsourced airport gate and ramp agent services, airport security fees, passenger interruption costs, deicing, landing fees and station rents. The $35.8 million, or 41.7%, increase in airport-related expenses for the year ended December 31, 2025, compared to the year ended December 31, 2024, was primarily due to an increase in subcontracted airport services, station rents, weather related aircraft deicing costs and landing fees as a result of an increase in the number of flights we operated under our prorate agreements. For clarity, our employee airport customer service labor costs are reflected in salaries, wages and benefits and customer service labor costs we outsource to third parties are included in airport-related expenses.

*Aircraft fuel.* The $33.0 million, or 37.7%, increase in fuel cost for the year ended December 31, 2025, compared to the year ended December 31, 2024, was primarily due to an increase in the number of flights we operated under our prorate agreements and under SWC and the corresponding increase in gallons of fuel we purchased, offset by a decrease in our average fuel cost per gallon from $3.19 in 2024 to $3.00 in 2025. We purchase and incur expense for all fuel on flights operated under our prorate agreements and SWC. All fuel costs incurred under our capacity purchase agreements are either purchased directly by our major airline partner, or if purchased by us, we record the direct reimbursement as a reduction to our fuel expense. The following table summarizes the gallons of fuel we purchased under our prorate agreements and SWC, for the periods indicated:

*Other operating expenses.* Other operating expenses primarily consist of aircraft rentals, property taxes, hull and liability insurance, simulator costs, crew per diem, crew hotel costs and credit loss reserves. The $31.2 million, or 10.4%, increase in other operating expenses for the year ended December 31, 2025, compared to the year ended December 31, 2024, was primarily related to an increase in operating expenses associated with our higher flight volume in 2025 compared to 2024, such as crew per diem and crew hotel costs, and an increase in our credit loss reserve in 2025 as a result of our assessment of higher credit risk of certain outstanding receivables.

*Summary of interest expense, interest income, other income (expense) and provision for income taxes:*

*Interest expense.* The $9.9 million, or 8.7%, decrease in interest expense for the year ended December 31, 2025, compared to the year ended December 31, 2024, was primarily related to a decrease in outstanding debt from $2.7 billion at December 31, 2024 to $2.4 billion at December 31, 2025. Our average effective interest rate for 2025 and 2024 was 4.3% and 4.2%, respectively.

*Interest income.* Interest income decreased $4.6 million, from $47.9 million for the year ended December 31, 2024 to $43.3 million for the year ended December 31, 2025. The decrease in interest income was primarily related to a decrease in interest rates earned on our marketable securities from December 31, 2024 to December 31, 2025.

*Other income, net.* Other income, net of expenses increased $5.0 million for the year ended December 31, 2025, compared to the year ended December 31, 2024. Other income, net primarily consists of the unrealized and realized gains and losses on our investments in other companies, income or loss related to our equity method investments and gains or losses on the sale of assets. The increase in other income, net of expenses was primarily a result of an increase in the fair value of our investments in other companies for the year ended December 31, 2025, compared to the year ended December 31, 2024.

*Provision for income taxes.* For the years ended December 31, 2025, and December 31, 2024, our effective income tax rates were 24.3% and 25.3%, respectively, which included the statutory federal income tax rate of 21.0% and other reconciling income tax items, including state income taxes and the impact of non-deductible expenses. For the year ended December 31, 2025, the lower effective tax rate was primarily related to a higher deduction benefit related to employee equity awards that vested in 2025 compared to 2024. Our income tax provision rate may fluctuate each reporting period based on various factors including, but not limited to, the amount of our non-deductible operating expenses, relative to our income before income taxes.

*Net income.* Primarily due to the factors described above, we generated net income of $428.3 million, or $10.35 per diluted share, for the year ended December 31, 2025, compared to net income of $323.0 million, or $7.77 per diluted share, for the year ended December 31, 2024.

*SkyWest Leasing Segment Profit.* SkyWest Leasing profit increased $9.4 million, or 3.2%, for the year ended December 31, 2025, compared to the year ended December 31, 2024, primarily due to an increase in revenue from maintenance services provided to third parties, a decrease in interest expense due to a decrease in outstanding debt from December 31, 2024 to December 31, 2025 and a decrease in depreciation and amortization expense primarily due to certain fixed assets that became fully depreciated during 2024 and as a result of extending the estimated useful lives on our CRJ700/CRJ550 fleet during the fourth quarter of 2024 with a full year effect in 2025. These increases in segment profit were partially offset by an increase in aircraft maintenance, materials and repairs due to incremental maintenance services provided to third parties and an increase in our credit loss reserve as a result of our assessment of the credit risk of the outstanding receivables.

**Liquidity and Capital Resources**

As of December 31, 2025, we had $706.9 million in cash and cash equivalents and marketable securities. As of December 31, 2025, we had $75.6 million available for borrowings under our line of credit. Given our available liquidity as of December 31, 2025, we believe the working capital currently available to us will be sufficient to meet our present financial requirements, including planned capital expenditures, scheduled lease payments and debt service obligations for at least the next 12 months.

Our total cash, cash equivalents and marketable securities decreased from $801.6 million as of December 31, 2024, to $706.9 million as of December 31, 2025, or by $94.7 million. Our total long-term debt, including current maturities decreased from $2.7 billion as of December 31, 2024, to $2.4 billion as of December 31, 2025, or by $0.3 billion, primarily due to scheduled debt payments for the 2025 year, partially offset by debt issued to finance seven new E175 aircraft. Additionally, we repurchased 0.8 million shares of our common stock for $84.5 million under a share repurchase program authorized by our Board of Directors during the year ended December 31, 2025. At December 31, 2025, our total capital mix (measured as a ratio of total stockholder equity and total long-term debt, including current maturities) was 53.4% equity and 46.6% total long-term debt, compared to 47.4% equity and 52.6% total long-term debt at December 31, 2024.

As of December 31, 2025 and 2024, we had $47.2 million and $47.1 million, respectively, in letters of credit and surety bonds outstanding with various banks and surety institutions. We had no restricted cash as of December 31, 2025 and 2024.

***Cash Flows provided by Operating Activities***

Our cash flows provided by operating activities was $940.4 million for the year ended December 31, 2025, compared to $692.5 million for the year ended December 31, 2024. Our operating cash flows are typically impacted by various factors including our net income, adjusted for non-cash expenses and gains such as depreciation expense, stock based compensation expense and gains or losses on the disposal of assets; and timing of cash payments and cash receipts attributed to our various current asset and liability accounts, such as accounts receivable, inventory, accounts payable, income taxes, accrued liabilities, deferred revenue and unbilled revenue.

The increase in our cash flow from operations for the year ended December 31, 2025, compared to the year ended December 31, 2024, was primarily due to an increase in income before income taxes for the year ended December 31, 2025, compared to the year ended December 31, 2024, and an increase in accounts payable and other liabilities due to the timing of cash payments for the comparable periods.

***Cash Flows used in Investing Activities***

Our cash flows used in investing activities was $651.8 million for the year ended December 31, 2025, compared to cash flows used in investing activities of $228.6 million for the year ended December 31, 2024. Our investing cash flows are typically impacted by various factors including our capital expenditures, such as the acquisition of aircraft and spare engines; deposit payments and refunds of previously made deposits on new aircraft; purchase and sales of marketable securities; proceeds from the sale of assets; and timing of cash payments and cash receipts attributed to our investments in other entities.

Excluding the purchase and sale of marketable securities, which results in the transfer of dollars between our investments in marketable securities and our cash accounts, our cash used in investing activities increased from $341.2 million for the year ended December 31, 2024, to $642.0 million for the year ended December 31, 2025. Excluding the transfer of dollars between our investments in marketable securities and our cash accounts, the remaining increase in cash used in investing activities was primarily due to an increase of $267.3 million used in the acquisition of property and equipment and an increase of $57.8 million used for aircraft deposits for the year ended December 31, 2025, compared to the year ended December 31, 2024, primarily due to the acquisition of seven new E175 aircraft and spare engines in 2025.

***Cash Flows used in Financing Activities***

Our cash flows used in financing activities was $393.2 million for the year ended December 31, 2025, compared to cash used in financing activities of $384.8 million for the year ended December 31, 2024. Our financing cash flows are typically impacted by various factors including proceeds from issuance of debt, principal payments on debt obligations, repurchases of our common stock and payment of cash dividends.

[**Table of Contents**](#Toc)

The $8.5 million increase in cash used in financing activities for the year ended December 31, 2025, compared to the year ended December 31, 2024, was primarily due to an increase of $41.6 million in cash used to purchase treasury stock and an increase of $20.3 million in cash used for employee income taxes paid on vested equity awards in lieu of shares, offset by an increase of $53.6 million in proceeds from the issuance of long-term debt for the purchase of seven new E175 aircraft, net of principal payments on long-term debt during the year ended December 31, 2025, compared to the year ended December 31, 2024.

**Significant Commitments and Obligations**

*General*

The following table summarizes our commitments and obligations for future minimum rental payments required under operating leases that had initial or remaining non-cancelable lease terms as of December 31, 2025, firm aircraft and spare engine commitments, interest commitments and principal maturities on long-term debt as noted for each of the next five years and thereafter (in thousands):

In addition to the table above, in 2024, we entered into a master equipment purchase agreement with another airline to acquire certain airframes and engines and lease the assets back to the airline under a five-year term. We accounted for the transaction as a failed sale-leaseback in accordance with Accounting Standard Codification Topic 842 as the criteria for a sale were not met. At December 31, 2025, we estimated the remaining financing obligation under the agreement will be between $20.0 million and $25.0 million and anticipated closing on the remaining financings during 2026.

*Purchase Commitments and Options*

As of December 31, 2025, we had a firm purchase commitment for 69 new E175 aircraft from Embraer with delivery dates anticipated into 2032. We also had firm purchase commitments to purchase two used E170 aircraft with anticipated delivery dates in 2026.

At the time of each aircraft acquisition, we evaluate the financing alternatives available to us and select one or more of these methods to fund the acquisition. In recent years, we have issued long-term debt to finance our new aircraft. At present, we intend to fund our aircraft purchase commitments through a combination of cash on hand and debt financing. Based on current market conditions and discussions with prospective leasing organizations and financial institutions, we currently believe that we will be able to obtain financing for our committed acquisitions, as well as additional aircraft. We intend to finance the firm purchase commitment for 69 E175 aircraft with approximately 75-85% debt and the remaining balance with cash. We intend to use cash to purchase the two used E170 aircraft.

*Aircraft Lease and Facility Obligations*

We also have long-term lease obligations, primarily relating to our facilities, aircraft and engines. Excluding aircraft financed by our major airline partners that we operate for them under contract, we had eight aircraft under lease with remaining terms ranging from three years to five years as of December 31, 2025. These eight leased aircraft are subleased to a third party. Future minimum lease payments due under all long-term operating leases were approximately $119.0 million at December 31, 2025. Assuming a 6.2% discount rate, which is the average incremental borrowing rate

[**Table of Contents**](#Toc)

we anticipate we would have incurred on debt obtained over a similar term to acquire these assets, the present value of these lease obligations would have been equal to approximately $81.9 million at December 31, 2025.

*Long-term Debt Obligations*

As of December 31, 2025, we had $2.4 billion of long-term debt, which consisted of $2.2 billion of debt used to finance aircraft and spare engines and $200.6 million of unsecured debt payable to Treasury. The average effective interest rate on our debt obligations was approximately 4.3% at December 31, 2025.

Under our capacity purchase agreements, our major airline partners compensate us for our costs of the aircraft on a monthly basis. The consideration for aircraft ownership costs we receive varies by agreement but is intended to compensate us for our ownership of the aircraft while the aircraft is under contract.

*Guarantees*

We have guaranteed the obligations of SkyWest Airlines under the United Express Agreement and the Delta Connection Agreement for the E175 aircraft. In addition, we have guaranteed certain other obligations under our aircraft financing and leasing agreements.

We have guaranteed $12.6 million in promissory notes of a third party in the event the third party defaults on their payments. The third party's loans are secured by aircraft and engines.

**Critical Accounting Policies and Estimates**

Our significant accounting policies are summarized in Note 1 to our Consolidated Financial Statements included in Item 8 of this Report. Critical accounting policies are those policies that are most important to the preparation of our consolidated financial statements and require management's subjective and complex judgments due to the need to make estimates about the effect of matters that are inherently uncertain. Our critical accounting policies relate to revenue recognition, long-lived assets and income tax as discussed below. The application of these accounting policies involves the exercise of judgment and the use of assumptions as to future uncertainties and, as a result, actual results will likely differ, and could differ materially, from such estimates.

*Revenue Recognition*

Flying agreements and airport customer service and other revenues are recognized when service is provided. Under our capacity purchase and prorate flying agreements with our major airline partners, our performance obligation is determined on a per completed flight basis. Under our capacity purchase agreements, the performance obligation of each completed flight is measured using block hours incurred for each completed flight, which factors the duration of each flight. Under our airport customer service agreements, our performance obligation is measured on a per departure basis for each flight we provide customer service.

A portion of our compensation under our capacity purchase agreements is designed to reimburse us for the use of the aircraft we provide under such agreements. This compensation is deemed to be lease revenue, because the agreements identify the "right of use" or a specific type and number of aircraft over the agreement term. We allocate the total consideration received under our capacity purchase agreements between the lease and non-lease components based on stand-alone selling prices. A portion of the consideration received for the use of the aircraft is a fixed monthly payment per aircraft. We recognize the fixed monthly lease payments as lease revenue using the straight-line basis over the capacity purchase agreement term and variable lease payments in the period when the block hours are completed. We recognized $13.9 million of previously deferred lease revenue and $5.6 million unbilled revenue during the year ended December 31, 2025, under the straight-line basis.

Additionally, a portion of our compensation under our capacity purchase agreements relates to operating the aircraft, identified as the non-lease component of the capacity purchase agreement. We recognize revenue attributed to the non-lease component received as fixed monthly payments per aircraft proportionate to the number of block hours completed during each reporting period, relative to the estimated number of block hours we anticipate completing over the remaining contract term. In 2025, we recognized $30.1 million of previously deferred fixed monthly payments as revenue and $8.2 million of unbilled revenue. The amount of deferred revenue and unbilled revenue from fixed monthly payments we recognize will increase or decrease in future reporting periods depending on the number of block hours we

[**Table of Contents**](#Toc)

complete during such reporting period and our then-current forecast of block hours we anticipate completing over the remaining contract term based on information available to us as that time.

Our revenues could be impacted by several factors, such as our flight schedules, passenger fares we receive under our prorate agreements, terminations, extensions or other amendments to our code-share agreements (which may also cause a reassessment of stand-alone selling prices of the lease and non-lease consideration), our estimates used to determine the amount of revenue we defer under our capacity purchase agreements, and our ability to earn incentive payments contemplated under applicable agreements. In the event contracted rates are not finalized at a quarterly or annual financial statement date, we record that period's revenues based on the lower of the prior period's approved rates or our estimate of rates that will be implemented upon completion of negotiations. Also, in the event we have a reimbursement dispute with a major airline partner at a quarterly or annual financial statement date, we evaluate the dispute under established revenue recognition criteria and, provided the revenue recognition criteria have been met, we recognize revenue for that period based on our estimate of the resolution of the dispute. Our rates were finalized under our code-share agreements as of December 31, 2025.

*Long-Lived Assets*

As of December 31, 2025, we had approximately $5.8 billion of property and equipment and related assets net of accumulated depreciation. In accounting for these long-lived assets, we make estimates about the expected useful lives of the assets, the expected residual values of certain of these assets, and the potential for impairment based on the fair value of the assets and the cash flows they generate. Factors indicating potential impairment include, but are not limited to, significant decreases in the market value of the long-lived assets, a significant change in the condition of the long-lived assets and operating cash flow losses associated with the use of the long-lived assets. When considering whether or not impairment of long-lived assets exists, we group similar assets together at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities and compare the undiscounted cash flows for each asset group to the net carrying amount of the assets supporting the asset group. Asset groupings are done at the fleet type or contract level.

Factors that may impact our estimates used for depreciation include anticipated useful lives of each aircraft type and estimated residual values of each aircraft. As we operate our aircraft under code-share agreements with our major airline partners, changes in anticipated demand by our major airline partners for regional aircraft may impact our estimated useful lives and residual values for our aircraft, spare engines and other long-lived assets.

*Income Tax*

Deferred income taxes are determined based on the temporary differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Estimating our tax liabilities involves judgments related to uncertainties in the application of complex tax regulations. We make certain estimates and judgments to determine tax expense for financial statement purposes as we evaluate the effect of tax credits, tax benefits and deductions, some of which result from differences in the timing of recognition of revenue or expense for tax and financial statement purposes. Changes to these estimates may result in significant changes to our tax provision in future periods. Each fiscal quarter we re-evaluate our tax provision and reconsider our estimates and assumptions related to specific tax assets and liabilities, making adjustments as circumstances change.

**Recent Accounting Pronouncements**

See Note 1 to the Consolidated Financial Statements included in Item 8 of this Report for a description of recent accounting pronouncements.

**ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

**Aircraft Fuel**

In the past, we have not experienced sustained material difficulties with fuel availability, and we currently expect to be able to obtain fuel at prevailing prices in quantities sufficient to meet our future needs. Pursuant to our capacity purchase agreements, United, Delta, American and Alaska have agreed to bear the economic risk of fuel price

[**Table of Contents**](#Toc)

fluctuations on our contracted flights. We bear the economic risk of fuel price fluctuations on our prorate and SWC operations. For each of the years ended December 31, 2025, 2024 and 2023, approximately 16%, 13% and 13% of our total flying agreements revenue was derived from prorate agreements and SWC. For the years ended December 31, 2025, 2024 and 2023, the average price per gallon of aircraft fuel was $3.00, $3.19 and $3.70, respectively. For illustrative purposes only, we have estimated the impact of the market risk of fuel price fluctuations on our prorate and SWC operations using a hypothetical increase of 25% in the price per gallon we purchase. Based on this hypothetical assumption, we would have incurred an additional $30.1 million, $21.9 million and $21.5 million in fuel expense for the years ended December 31, 2025, 2024 and 2023, respectively.

**Interest Rates**

As of December 31, 2025, our long-term debt secured by aircraft and spare engines had fixed interest rates. We currently intend to finance the acquisition of aircraft through long-term debt. Changes in interest rates may impact our actual cost to acquire future aircraft. To the extent we place new aircraft in service under our capacity purchase agreements with United, Delta, American, Alaska or other carriers, our capacity purchase agreements currently provide that reimbursement rates will be adjusted to reflect the interest rates effective at the closing of the respective aircraft financing. As such, a hypothetical 50 basis point change in market interest rates would not have a material effect on our financial results. At December 31, 2025, of the $200.6 million in unsecured debt payable to Treasury, $95.4 million had a fixed interest rate of 1.0% and the remaining $105.2 million had a variable interest rate of the applicable Secured Overnight Financing Rate ("SOFR") plus 2.0%. The interest rate under the $95.4 million unsecured loans is scheduled to increase to the applicable SOFR rate plus 2.0% upon the fifth anniversary of each disbursement. We received disbursements under these unsecured loans from January 2021 through April 2021. We use the effective interest rate method to record interest expense assuming the unsecured loans are outstanding for the full 10-year term.

**Labor and Inflation Risk**

The global economy has experienced, and continues to experience high rates of inflation. We cannot predict how long these inflationary pressures will continue, or how they may change over time, but we expect to see continued impacts on the global economy and our Company.

As a result, our costs have become, and we expect they will continue to be, subject to inflationary pressures, and we may not be able to fully offset such higher costs through price increases under our capacity purchase agreements. Salaries, wages and benefits expense represented 45.3% of our total operating expense for year ended December 31, 2025. For illustrative purposes, a hypothetical increase of 25% to our salaries, wages and benefits during the year ended December 31, 2025, would have increased our operating expenses by approximately $389.8 million.

Our inability or failure to offset a material increase in costs due to inflation and/or labor costs could harm our business, financial condition and operating results. Additionally, in the event we are unable to hire and retain qualified pilots or other operational personnel, including flight attendants and maintenance technicians, we may be unable to operate requested flight schedules under our capacity purchase agreements, which could result in a reduction in revenue and operating inefficiencies, such as incremental new-hire training costs, and could harm our business, financial condition and operating results.

| &nbsp;&nbsp;*Description of the Matter* | &nbsp;&nbsp;At December 31, 2025, the Company's deferred revenue balance totaled $292.4 million, of which $163.9 million was presented as a component of other current liabilities and $128.5 million was included in other long-term liabilities on the balance sheet. As discussed in Note 1 to the consolidated financial statements, under the Company's capacity purchase agreements, the Company is paid a fixed amount per aircraft each month over the contract term. The Company recognizes revenue related to the fixed amount per aircraft each month based upon completed block hours proportionate to total forecasted block hours over the remaining contract term. To calculate the amount of revenue  |

We also tested controls over management's review of the data used in the deferred revenue calculation.<br>To test the Company's deferred revenue liability, we performed audit procedures that included, among others, assessing the methodology and assumptions used by the Company in the deferred revenue calculation, including testing of the forecasted block hours and validating completeness and accuracy of the underlying data used by the Company. Specifically, we compared management's forecasted block hours to historical flight activity and existing flight schedules with partner airlines. We evaluated management's ability to accurately forecast flight activity by performing hindsight analyses comparing actual historical results to past forecasts. We also performed sensitivity analyses to understand the impact of fluctuations in forecasted block hours to the deferred revenue liability.<br>|

| &nbsp;&nbsp;Total Fleet | 270 | 51 | 178 | 138 | 637 |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) As of December 31, 2025, other aircraft included: supplemental spare aircraft supporting the Company's code-share agreements that may be placed under future code-share or leasing agreements, aircraft scheduled to be placed under a code-share agreement with one of the Company's major airline partners or aircraft that are scheduled to be disassembled for use as spare parts.

For the year ended December 31, 2025, approximately 44.4% of the Company's aircraft in scheduled service was operated for United, approximately 28.1% was operated for Delta, approximately 18.9% was operated for American and approximately 8.6% was operated for Alaska.

SkyWest Airlines has been a code-share partner with Delta since 1987, United since 1997, Alaska since 2011 and American since 2012. As of December 31, 2025, SkyWest Airlines operated as a Delta Connection carrier primarily in Salt Lake City, Detroit, Los Angeles, Minneapolis and the Pacific Northwest, a United Express carrier primarily in Los Angeles, San Francisco, Denver, Houston and Chicago, an American carrier primarily in Chicago, Dallas, Los Angeles and Phoenix and an Alaska carrier primarily in the Pacific Northwest.

SkyWest Airlines operates the following aircraft manufactured by MHI RJ Aviation ULC, formerly known as Bombardier Aerospace ("Bombardier"): CRJ900s, CRJ700s, including a 50-seat configuration of the CRJ700, commonly referred to as a "CRJ550," and CRJ200s, and E175s manufactured by Embraer S.A. ("Embraer"). The CRJ700, CRJ550, CRJ900 and E175 aircraft, commonly referred to as "dual-class aircraft," have a first class seat configuration typically configured between 50 to 76 seats. SkyWest Airlines operates the CRJ200 as a single-class, 50-seat aircraft and SWC operates the CRJ200 in a 30-seat configuration.

***Basis of Presentation***

The Company's consolidated financial statements include the accounts of the Company and the SkyWest Airlines and SWC and SkyWest Leasing segments, with all inter-company transactions and balances having been eliminated.

[**Table of Contents**](#Toc)

In preparing the accompanying consolidated financial statements, the Company has reviewed, as determined necessary by the Company's management, events that have occurred after December 31, 2025, through the filing date of the Company's annual report with the U.S. Securities and Exchange Commission.

***Use of Estimates***

The preparation of financial statements in conformity with accounting principles generally accepted in the United States ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates and assumptions.

***Cash and Cash Equivalents***

The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. The Company had no restricted cash as of December 31, 2025 and 2024.

***Marketable Securities***

The Company's investments in debt securities are classified as available-for-sale and are reported at fair market value with the net unrealized appreciation (depreciation) reported as a component of accumulated other comprehensive income in stockholders' equity. At the time of sale, any realized appreciation or depreciation, calculated by the specific identification method, is recognized in other income and expense. The Company's position in marketable securities as of December 31, 2025 and 2024 was as follows (in thousands):

---

| | | | | |
|:---|:---|:---|:---|:---|
| **At December 31, 2025** | <br>**Amortized Cost** | **Gross unrealized**<br>**holding gains** | **Gross unrealized**<br>**holding losses** | <br>**Fair market value** |
| Marketable securities: |  |  |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Bond and bond funds | $487331 | $443 | $(75) | $487699 |
| &nbsp;&nbsp;&nbsp;&nbsp;Commercial Paper | 96537 |  |  | 96537 |
| &nbsp;&nbsp;Total marketable securities | $583868 | $443 | $(75) | $584236 |

---

| | | | | |
|:---|:---|:---|:---|:---|
| **At December 31, 2024** | <br>**Amortized Cost** | **Gross unrealized**<br>**holding gains** | **Gross unrealized**<br>**holding losses** | <br>**Fair market value** |
| Marketable securities: |  |  |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Bond and bond funds | $462111 | $313 | $(91) | $462333 |
| &nbsp;&nbsp;&nbsp;&nbsp;Commercial Paper | 111933 |  |  | 111933 |
| &nbsp;&nbsp;Total marketable securities | $574044 | $313 | $(91) | $574266 |

---

As of December 31, 2025 and 2024, the Company had classified $584.2 million and $574.3 million of marketable securities, respectively, as short-term because it had the intent to maintain a liquid portfolio and the ability to redeem the securities within one year.

***Inventories***

Inventories include expendable parts and supplies and are valued at cost (FIFO basis) less an allowance for obsolescence based on historical part turnover, excess parts and management's expectations of future operations. Expendable inventory parts are charged to expense as used. An obsolescence allowance for flight equipment expendable parts is accrued based on estimated lives of the corresponding fleet types, anticipated part usage and salvage values. The inventory allowance as of December 31, 2025 and 2024, was $32.3 million and $28.8 million, respectively.

[**Table of Contents**](#Toc)

***Property and Equipment***

Property and equipment are stated at cost and depreciated over their useful lives to their estimated residual values using the straight-line basis. The Company revises its estimated useful life and residual values assumptions when facts and circumstances occur, particularly as the Company's CRJ fleet ages. Effective November 1, 2025, the Company extended the estimated useful lives of certain CRJ airframes and CRJ rotable spare parts by five to seven years to align with the Company's long-term fleet plan and adjusted residual values on its spare engines to reflect current market conditions. Additionally, at December 31, 2025, the Company extended the useful lives of certain spare engines and E175 rotable spare parts by 7 to 12 years to align with the Company's long-term fleet plan. The effect of these changes was not material to the consolidated financial statements. The following summarizes the Company's useful life and residual value assumptions as of December 31, 2025:

---

| | | |
|:---|:---|:---|
| **Assets** | **Depreciable Life** | **Current Residual Value** |
| Aircraft, rotable spares, and spare engines | up to 27 years | up to 20% |
| Ground equipment | up to 10 years | 0% |
| Office equipment | up to 5 years | 0% |
| Leasehold improvements | Shorter of 15 years or lease term | 0% |
| Buildings | 20 - 39.5 years | 0% |

---

***Impairment of Long-Lived Assets***

As of December 31, 2025, the Company had approximately $5.8 billion of property and equipment, net of accumulated depreciation. In accounting for these long-lived assets, the Company makes estimates about the expected useful lives of the assets, the expected residual values of such assets, and the potential for impairment based on projected future cash flows and estimated fair value of the assets. Factors indicating potential impairment include, but are not limited to, significant decreases in the market value of the long-lived assets, a significant change in the condition of the long-lived assets and operating cash flow losses associated with the use of the long-lived assets. On a periodic basis, the Company evaluates whether impairment indicators are present. When considering whether or not impairment of long-lived assets exists, the Company groups similar assets together at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities and compare the undiscounted cash flows for each asset group to the net carrying amount of the assets supporting the asset group. Asset groupings are done at the aircraft type level.

***Capitalized Interest***

Interest is capitalized on aircraft purchase deposits as a portion of the cost of the asset and is depreciated over the estimated useful life of the asset. During the years ended December 31, 2025, 2024 and 2023, the Company capitalized interest costs of approximately $3.5 million, $3.3 million and $1.5 million, respectively.

***Maintenance***

The Company operates under a U.S. Federal Aviation Administration approved continuous inspection and maintenance program. The Company uses the direct expense method of accounting for its regional jet engine overhauls. The Company has engine services agreements with third-party vendors to provide long-term engine services covering the scheduled and unscheduled repairs for most of its aircraft. Under the terms of the agreements, the Company pays a fixed dollar amount per engine hour flown per month and the third-party vendors will assume the responsibility to repair the engines at no additional cost to the Company, subject to certain specified exclusions. Maintenance costs under these contracts are recognized when the engine hour is flown pursuant to the terms of each contract. The repair costs for engines not covered by these hourly service agreements are expensed when repair services are incurred. The costs of maintenance for airframe and avionics components, landing gear and other recurring maintenance are expensed as incurred.

***Flying Agreements and Airport Customer Service and Other Revenues***

The Company recognizes revenue under its flying agreements and under its lease, airport services and other service agreements when the service is provided under the applicable agreement. Under the Company's capacity purchase agreements with United, Delta, American and Alaska (each, a "major airline partner"), the major airline partner

[**Table of Contents**](#Toc)

generally pays the Company a fixed-fee for each departure, flight hour (measured from takeoff to landing, excluding taxi time) or block hour (measured from takeoff to landing, including taxi time) incurred, and an amount per aircraft in service each month, with additional incentives based on flight completion, on-time performance or other performance metrics. The major airline partner also directly pays for or reimburses the Company for certain direct expenses incurred under the capacity purchase agreement, such as fuel, airport landing fees and airport rents. Under the capacity purchase agreements, the Company's performance obligation is met when each flight is completed, measured in completed block hours, and is reflected in flying agreements revenue. The transaction price for the capacity purchase agreements is determined from the fixed-fee consideration, incentive consideration and directly reimbursed expenses earned as flights are completed over the agreement term. For the years ended December 31, 2025, 2024 and 2023, capacity purchase agreements represented approximately 84.3%, 86.6% and 86.5% of the Company's flying agreements revenue, respectively.

Under the Company's prorate agreements, the major airline partner and the Company negotiate a passenger fare proration formula, pursuant to which the Company receives a percentage of the ticket revenues for those passengers traveling for one portion of their trip on a Company airline and the other portion of their trip on the major airline partner. Under the Company's prorate agreements, the performance obligation is met and revenue is recognized when each flight is completed based upon the portion of the prorate passenger fare the Company determines that it will receive for each completed flight. The transaction price for the prorate agreements is determined from the proration formula derived from each passenger ticket amount on each completed flight over the agreement term. Certain routes under the Company's prorate agreements are subsidized by the U.S. Department of Transportation under the Essential Air Service ("EAS") program, a program created to ensure small communities in the United States maintain a minimum level of scheduled air service. The EAS contracts are generally between two and three years in duration and the Company recognizes EAS revenue on a per-completed-flight basis pursuant to the terms of each contract. In the event the Company receives upfront consideration for an EAS contract, the Company recognizes the revenue on a per-completed flight basis over the EAS contract term. Under the Company's charter operations, SWC, the Company negotiates a fare for the charter flight with the customer. The performance obligation is met and revenue is recognized upon completion of the flight. For the years ended December 31, 2025, 2024 and 2023, prorate agreements and SWC revenue represented approximately 15.7%, 13.4%, and 13.5% of the Company's flying agreements revenue, respectively.

The following table represents the Company's flying agreements revenue by type for the years ended December 31, 2025, 2024 and 2023 (in thousands):

---

| | | | |
|:---|:---|:---|:---|
|  | **For the year ended December 31,**  | **For the year ended December 31,**  | **For the year ended December 31,**  |
|  | **2025** | **2024** | **2023** |
| Capacity purchase agreements flight operations revenue (non-lease component) | $2590735 | $2415598 | $1976743 |
| Capacity purchase agreements fixed aircraft lease revenue | 441262 | 303134 | 296047 |
| Capacity purchase agreements variable aircraft lease revenue | 242743 | 236676 | 180218 |
| Prorate agreements and SWC revenue | 610413 | 457390 | 381389 |

The Company allocates the total consideration received under its capacity purchase agreements between lease and non-lease components based on stand-alone selling prices. A portion of the Company's compensation under its capacity purchase agreements relates to operating the aircraft, identified as the non-lease component of the capacity purchase agreement. The Company recognizes revenue attributed to the non-lease component received as fixed-fees for each departure, flight hour or block hour on an as-completed basis for each reporting period. The Company recognizes revenue attributed to the non-lease component received as fixed monthly payments per aircraft proportionate to the number of block hours completed during each reporting period, relative to the estimated number of block hours the Company anticipates completing over the remaining contract term. Accordingly, the Company's revenue recognition will likely vary from the timing of cash receipts under the Company's capacity purchase agreements. The Company refers to cash received under its capacity purchase agreements prior to recognizing revenue as "deferred revenue," and the Company refers to revenue recognized prior to billing its major airline partners under its capacity purchase agreements as "unbilled revenue" for each reporting period.

[**Table of Contents**](#Toc)

A portion of the Company's compensation under its capacity purchase agreements is designed to reimburse the Company for certain aircraft ownership costs. The consideration for aircraft ownership costs varies by agreement but is intended to compensate the Company for providing its aircraft under the contract. The consideration received for the use of the aircraft under the Company's capacity purchase agreements is accounted for as lease revenue, inasmuch as the agreements identify the "right of use" of a specific type and number of aircraft over a stated period of time. The lease revenue associated with the Company's capacity purchase agreements is accounted for as an operating lease and is reflected as flying agreements revenue on the Company's consolidated statements of comprehensive income. The Company recognizes fixed monthly lease payments as lease revenue using the straight-line basis over the capacity purchase agreement term and variable lease payments in the period when the block hours are completed. The Company has not separately stated aircraft rental income and aircraft rental expense in the consolidated statement of comprehensive income because the use of the aircraft is not a separate activity of the total service provided under the capacity purchase agreements.

The following table summarizes the amount of deferred revenue, recognition of previously deferred revenue and change in unbilled revenue for the fixed monthly non-lease and lease payments received under the Company's capacity purchase agreements for the years ended December 31, 2025, 2024 and 2023 (in thousands):

The Company's capacity purchase and prorate agreements include weekly provisional cash payments from the respective major airline partner based on a projected level of flying each month. The Company and each major airline partner subsequently reconcile these payments to the actual completed flight activity on a monthly or quarterly basis.

In several of the Company's agreements, the Company is eligible to receive incentive compensation upon the achievement of certain performance criteria. The incentives are defined in the agreements and are measured and determined on a monthly or annual basis. At the end of each period during the term of an agreement, the Company calculates the incentives achieved during that period and recognizes revenue attributable to that agreement accordingly, subject to the variable constraint guidance under Accounting Standard Codification ("ASC") Topic 606.

The following summarizes the significant provisions of each code-share agreement the Company has with each major airline partner through SkyWest Airlines:

\* The Company's prorate agreements are based on specific routes, not a specific aircraft count. The number of aircraft listed above for each prorate agreement approximates the number of aircraft the Company uses to serve the prorate routes.

In addition to the contractual agreements described above, as of December 31, 2025, SkyWest Airlines reached agreements with certain major airline partners to place additional aircraft under capacity purchase agreements as summarized below. The Company is coordinating with its major airline partners and aircraft manufacturer regarding the timing of upcoming fleet deliveries and the delivery timing referenced below is subject to change.

[**Table of Contents**](#Toc)

● Capacity purchase agreement with United for eight new E175 aircraft, which are scheduled for delivery in 2026. The Company anticipates financing the aircraft through debt.

● Capacity purchase agreement with Alaska for one new E175 aircraft, which is scheduled for delivery in 2026. The Company anticipates financing the aircraft through debt.

● Capacity purchase agreement with Delta for 16 new E175 aircraft. 10 new E175 aircraft are currently scheduled for delivery in 2027 and six new E175 aircraft are scheduled for delivery in 2028. The Company anticipates financing the aircraft through debt.

● Capacity purchase agreement with United for 23 used CRJ550 aircraft that are anticipated to be placed into service by the end of 2026. Pursuant to these agreements, the Company is in the process of converting its owned CRJ700s to CRJ550s.

In January 2026, the Company extended the scheduled contract expirations on 40 E175 aircraft with United and 13 E175 aircraft with Delta. The termination dates in the table above reflect the January 2026 extensions.

When an aircraft is scheduled for expiration from a capacity purchase agreement, the Company may, as practical under the circumstances, negotiate an extension with the respective major airline partner, negotiate the placement of the aircraft with another major airline partner, return the aircraft to the major airline partner when the aircraft is provided by the major airline partner, place owned aircraft for sale or pursue other uses for the aircraft. Other uses for the aircraft may include placing the aircraft in a prorate agreement, leasing the aircraft to a third party or disassembling aircraft components such as the engines and parts to be used as spare inventory.

Lease, airport services and other revenues primarily consist of revenue generated from aircraft and spare engines leased to third parties, maintenance services provided to third parties and airport customer service agreements, such as gate and ramp agent services at various airports where the Company has been contracted by third parties to provide such services. The following table represents the Company's lease, airport services and other revenues for the years ended December 31, 2025, 2024 and 2023 (in thousands):

Of the Company's $5.8 billion of property and equipment, net of accumulated depreciation as of December 31, 2025, $238.7 million of regional jet aircraft and spare engines were leased to third parties under operating leases. The Company's mitigation strategy for the residual asset risks of these assets includes leasing aircraft and engine types that can be operated by the Company in the event of a default. Additionally, the operating leases typically have specified lease return condition requirements paid by the lessee to the Company and the Company typically maintains inspection rights under the leases.

The transaction price for airport customer service agreements is determined from an agreed-upon rate by location applied to the applicable number of flights handled by the Company over the agreement term.

[**Table of Contents**](#Toc)

The Company's operating revenues could be impacted by several factors, including changes to the Company's code-share agreements with its major airline partners, changes in flight schedules, contract modifications resulting from contract renegotiations, the Company's ability to earn incentive payments contemplated under the Company's code-share agreements and settlement of reimbursement disputes with the Company's major airline partners.

Other ancillary revenues commonly associated with airlines, such as baggage fee revenue, ticket change fee revenue and the marketing component of the sale of mileage credits, are retained by the Company's major airline partners on flights that the Company operates under its code-share agreements.

As of December 31, 2025, the Company had $159.8 million in accounts receivable of which $129.0 million is related to flying agreements. As of December 31, 2024, the Company had $122.8 million in accounts receivable of which $105.2 million is related to flying agreements.

***Allowance for Credit Losses***

The Company has an allowance for credit losses associated with its accounts receivable, notes receivable and third-party debt guarantees. The Company monitors publicly available credit ratings for entities for which the Company has a significant receivable balance or guarantee. As of December 31, 2025, the Company had gross receivables of $163.3 million in current assets and gross receivables of $266.3 million in other long-term assets. As of December 31, 2024, the Company had gross receivables of $125.9 million in current assets and gross receivables of $225.2 million in other long-term assets. The Company has established credit loss reserves based on publicly available historic default rates issued by a third party for companies with similar credit ratings, factoring in the amount and term of the Company's respective accounts receivable, notes receivable or guarantees. During the year ended December 31, 2025, the Company increased its credit loss reserve by $7.5 million primarily due to the increase in receivables from December 31, 2024 to December 31, 2025 and the Company's assessment of higher credit risk of certain outstanding receivables. During the year ended December 31, 2024, the Company recorded $3.6 million of adjustments as reductions to the credit loss reserve. During the year ended December 31, 2023, the Company recorded $0.2 million of adjustments to the credit loss reserve and wrote-off $18.5 million in receivables that were fully reserved as of December 31, 2022. There were no other significant changes in the outstanding accounts receivable, notes receivable, guarantees or credit ratings of the entities.

The following table summarizes the changes in allowance for credit losses:

***Income Taxes***

The Company recognizes a net liability or asset for the deferred tax consequences of all temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements that are expected to result in taxable or deductible amounts in future years when the reported amounts of the assets and liabilities are recovered or settled.

***Net Income Per Common Share***

Basic net income per common share ("Basic EPS") excludes dilution and is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per common share ("Diluted EPS") reflects the potential dilution that could occur if stock options or other contracts to issue common stock

[**Table of Contents**](#Toc)

were exercised or converted into common stock. The computation of Diluted EPS does not assume exercise or conversion of securities that would have an anti-dilutive effect on net income per common share. Securities that could potentially dilute Basic EPS in the future, and which were excluded from the calculation of Diluted EPS because inclusion of such share would be anti-dilutive, are as follows (in thousands):

&nbsp;&nbsp;&nbsp;&nbsp;(1) Warrants originally issued to U.S. Department of the Treasury ("Treasury") to purchase shares of SkyWest common stock issued pursuant to the three Payroll Support Program Agreements and a loan agreement with the U.S. Treasury. See Note 9, "Capital Transactions" for further discussion on the warrants issued to Treasury.

Additionally, for the years ended December 31, 2025, 2024 and 2023, 79,000, 209,000 and 334,000 performance share units ("PSUs") (at target performance) were excluded from the computation of Diluted EPS because the Company had not achieved the minimum target thresholds for these PSUs as of December 31, 2025, 2024 and 2023, respectively.

The calculation of the weighted average number of common shares outstanding for Basic EPS and Diluted EPS are as follows for the years ended December 31, 2025, 2024 and 2023 (in thousands):

***Comprehensive Income***

Comprehensive income includes charges and credits to stockholders' equity that are not the result of transactions with the Company's shareholders, including changes in unrealized appreciation or depreciation on marketable debt securities.

***Fair Value of Financial Instruments***

The carrying amounts reported in the consolidated balance sheets for receivables and accounts payable approximate fair values because of the immediate or short-term maturity of these financial instruments. Marketable securities are reported at fair value based on market quoted prices in the consolidated balance sheets. Certain investments in other companies are reported at fair value based on market quoted prices or using the Black Scholes Option Pricing model in the consolidated balance sheets. The fair value of the Company's long-term debt, as disclosed in Note 3, is estimated based on current rates offered to the Company for similar debt.

***Segment Reporting***

GAAP requires disclosures related to components of a company for which separate financial information is available to, and regularly evaluated by, the Company's chief operating decision maker when deciding how to allocate

[**Table of Contents**](#Toc)

resources and in assessing performance. The Company's two reportable segments consist of (1) the operations of SkyWest Airlines and SWC (collectively, "SkyWest Airlines and SWC") and (2) SkyWest Leasing activities. Information pertaining to the Company's reportable segments is presented in Note 2, *Segment Reporting*.

***Recent Accounting Pronouncements***

At December 31, 2025, the Company adopted Accounting Standards Update No. 2023-09 ("ASU 2023-09"), "Income Taxes (ASC Topic 740) – Improvements to Income Tax Disclosures," issued by the Financial Accounting Standards Board (FASB). The standard enhances the transparency, effectiveness and comparability of income tax disclosures by requiring consistent categories and greater disaggregation of information related to income tax rate reconciliations and the jurisdictions in which income taxes are paid. As required by the standard, the Company recast prior year disclosures to conform to the current year presentation. The adoption of this standard did not have a material impact on the Company's consolidated financial statements. For further details, refer to Note 4, *Income Taxes*.

In March 2024, the FASB issued Accounting Standards Update No. 2024-03, "Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (ASC Subtopic 220-40) – Disaggregation of Income Statement Expenses", which enhances the transparency and comparability of financial statements by requiring companies to disclose more granular information about expense components. As clarified in ASU 2025-01, "Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the effective date," the guidance is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the potential impact of adopting this new guidance on its consolidated financial statements and related disclosures.

**(2) Segment Reporting**

GAAP requires disclosures related to components of a company for which separate financial information is available to, and regularly evaluated by, the Company's chief operating decision maker when deciding how to allocate resources and in assessing performance. The Company's chief operating decision maker is the chief executive officer.

The Company's two reportable segments consist of (1) the operations of SkyWest Airlines and SWC and (2) SkyWest Leasing activities.

The Company's chief operating decision maker analyzes the profitability of operating aircraft separately from the profitability of the Company's capital deployed for new aircraft and the related aircraft financings, including the Company's E175 fleet. The SkyWest Airlines and SWC segment includes revenue earned under the applicable capacity purchase agreements attributed to operating such aircraft and the respective operating costs, and revenue and operating expenses attributed to prorate agreements and airport services agreements. The SkyWest Leasing segment includes applicable revenue earned under the applicable capacity purchase agreements attributed to the ownership of new aircraft acquired through the issuance of debt and the respective depreciation and interest expense of such aircraft. The SkyWest Leasing segment also includes the activity of leasing regional jet aircraft and spare engines to third parties and other activities. The SkyWest Leasing segment's total assets and capital expenditures include new aircraft acquired through the issuance of debt and assets leased to third parties.

The chief operating decision maker assesses performance for each segment and decides how to allocate resources based on income before income taxes. The chief operating decision maker uses the segment profit or loss measure when assessing performance of the segment and monitors budget versus actual results to allocate resources for each segment predominantly in the annual budget and forecasting process.

The following represents the Company's segment data for the years ended December 31, 2025, 2024, and 2023 (in thousands). As required by the adoption of ASC 2023-07 for the year ended December 31, 2024, the Company recast the 2023 segment disclosures to conform to the 2025 and 2024 presentation.

The Company's deferred tax liabilities were primarily generated through accelerated depreciation, combined with shorter depreciable tax lives, allowed under the IRS tax code for purchased aircraft and support equipment compared to the Company's depreciation policy under GAAP for such assets (see Note 1, "Nature of Operations and Summary of Significant Accounting Policies").

At December 31, 2025 and 2024, the Company had federal net operating losses of approximately $269.1 million and $377.9 million and state net operating losses of approximately $239.4 million and $280.3 million, respectively.

The Company anticipates that the federal and state net operating losses will start to expire in 2035 and 2026, respectively. The Company has no ongoing federal examination and has one ongoing state examination. Federal tax years 2022, 2023 and 2024 are open to examination.

**(5) Commitments and Contingencies**

***Self-Insurance***

The Company self-insures a portion of its potential losses from claims related to workers' compensation, environmental issues, property damage, medical insurance for employees and general liability. Losses are accrued based on an estimate of the ultimate aggregate liability for claims incurred, using standard industry practices and the Company's actual experience. The Company uses judgment and estimates in determining the ultimate aggregate liabilities for claims incurred in its workers' compensation liability. The Company also used assumptions in determining the workers compensation liability such as an estimation of loss payment and loss reporting development patterns. At December 31, 2025 and 2024, the Company's accrued workers' compensation liability totaled $19.1 million and $18.5 million, respectively, of which $9.8 million and $9.0 million, respectively, was short-term and included in other current liabilities. Actual results could differ from these estimates.

***Legal Matters***

The Company is subject to certain legal actions which it considers routine to its business activities. As of December 31, 2025, management believed, after consultation with legal counsel, that the ultimate outcome of such legal matters was not likely to have a material adverse effect on the Company's financial position, liquidity or results of operations.

***Concentration Risk and Significant Customers***

The Company requires no collateral from its major airline partners or customers, but monitors the financial condition of its major airline partners. Under the majority of the Company's code-share agreements, the Company receives weekly payments from its major code-share partners that approximate a significant percentage of the compensation earned for such period. Additionally, the Company provides certain customer service functions at multiple airports for various airlines and the Company maintains a credit loss reserve based upon expected collectability of all accounts receivable. For the years ended December 31, 2025, 2024, and 2023, the Company's contractual relationships with Delta and United combined accounted for approximately 70.3%, 72.3% and 70.9%, respectively of the Company's total revenues.

***Employees Under Collective Bargaining Agreements***

As of December 31, 2025, the Company had approximately 15,800 employees. Although no SkyWest Airlines employees are represented by a national union, the majority of SkyWest Airlines' employees are covered by a written, stable and binding collective bargaining agreement under the Railway Labor Act, entered into between SkyWest Airlines and long-established labor associations, such as the SkyWest Airlines Pilot Association ("SAPA").

[**Table of Contents**](#Toc)

***Aircraft and Other Purchase Commitments***

As of December 31, 2025, the Company had a purchase commitment to purchase 69 new E175 aircraft from Embraer with anticipated delivery dates through 2032, including a purchase agreement the Company entered into with Embraer during the second quarter of 2025. Under this commitment, the Company expects to purchase and place into service eight E175 aircraft with United, one E175 aircraft with Alaska and 16 E175 aircraft with Delta. The remaining purchase commitment delivery positions for 44 E175 aircraft are from 2028 through 2032. The Company also had a purchase agreement to acquire two used E170 aircraft with anticipated closing dates in 2026.

In addition to the above, in 2024, the Company entered into a master equipment purchase agreement with another airline to acquire certain airframes and engines and lease the assets back to the airline under a five-year term. The Company accounted for the transaction as a failed sale-leaseback in accordance with ASC 842 as the criteria for a sale were not met. At December 31, 2025, the Company estimates the remaining financing obligation under the agreement will be between $20.0 million and $25.0 million and anticipates closing on the remaining financings during 2026.

***Guarantees***

In 2022, the Company agreed to guarantee $19.8 million of debt for a 14 CFR Part 135 air carrier. The debt is secured by the Part 135 air carrier's aircraft and engines and has a five-year term. In exchange for providing the guarantee, the Company received 6.5% of the guaranteed amount as consideration, payable in the estimated value of common stock of the Part 135 air carrier, all of which was sold in 2023. The balance of the debt under the guarantee was $12.6 million as of December 31, 2025.

In 2023, the Company agreed to guarantee up to $12.0 million of debt for an aviation school. The debt was secured by the school's aircraft and engines and had a five-year term. In exchange for providing the guarantee, the Company received 2.0% of the guaranteed amount annually as consideration in cash. In June 2025, the aviation school fully repaid the debt under the guarantee agreement. As a result, the Company was no longer a guarantor at December 31, 2025.

The purpose of these guarantees is to help reduce the financing costs of aircraft for the third-parties in an effort to increase the potential number of commercial pilots in the Company's hiring pipeline. The Company also recorded the estimated credit loss associated with the guarantees based on publicly available historical default rates issued by a third party for companies with similar credit ratings, factoring the collateral and guarantee term.

**(6) Leases**

The Company leases property and equipment under operating leases. For leases with durations longer than 12 months, the Company recorded the related operating lease right-of-use asset and operating lease liability at the present value of lease payments over the term. The Company used its incremental borrowing rate to discount the lease payments based on information available at lease commencement.

***Aircraft***

As of December 31, 2025, excluding aircraft financed by the Company's major airline partners that the Company operates for them under contract, the Company leased eight aircraft under long-term lease agreements with remaining terms ranging from three to five years. The Company is subleasing these eight aircraft to a third party.

***Airport facilities***

The Company has operating leases for facility space including airport terminals, office space, cargo warehouses and maintenance facilities. The Company generally leases this space from government agencies that control the use of the various airports. The remaining lease terms for facility space vary from one month to 31 years. The Company's operating leases with lease rates that are variable based on airport operating costs, use of the facilities or other variable factors are excluded from the Company's right-of-use assets and operating lease liabilities in accordance with accounting guidance.

***Leases***

As of December 31, 2025, the Company's right-of-use assets were $81.9 million, the Company's current maturities of operating lease liabilities were $19.6 million, and the Company's noncurrent lease liabilities were $62.3 million.

The Company's "Marketable Securities" classified as Level 2 securities primarily utilize broker quotes in a non-active market for valuation of these securities.

During the year ended December 31, 2025, the Company exercised its warrant to purchase 1,500,000 shares of common stock of Eve Holding, Inc. ("Eve") through a cashless exercise and received shares of common stock of Eve. See Note 12 "Investments in Other Companies" for additional information regarding the Company's investment in Eve. The warrant was classified as Level 3 within the fair value hierarchy as of December 31, 2024. The Company's shares of Eve's common stock are actively traded and are valued using quoted market prices and are classified as Level 1 within the fair value hierarchy as of December 31, 2025. The Company's policy regarding the recording of transfers between levels is to record any such transfers at the end of the reporting period.

**(8) Assets Held for Sale**

In 2022, the Company committed to a formal plan to sell 14 CRJ700 aircraft and determined the aircraft met the criteria to be classified as assets held for sale. During 2023, the Company recorded a $2.3 million loss related to changes in the fair value of the 14 aircraft held for sale which is included in "Other operating expenses" on the Company's consolidated statements of comprehensive income and in the SkyWest Leasing segment for the year ended December 31, 2023.

In March 2024, the Company decided not to sell the 14 CRJ700 aircraft based on improved pilot availability and reclassified them as held for use assets in "Aircraft and rotable spares" on the Company's consolidated balance sheet. The Company remeasured the fair value of the held for use assets at the time of the reclassification and, as a result, the Company recorded a $4.2 million gain (pre-tax), as an offset to "Other Operating Expenses" in the Company's consolidated statement of income during the year ended December 31, 2024, primarily due to the elimination of the estimated costs to sell the assets.

The fair values were based upon observable and unobservable inputs, including a third-party valuation, market trends and condition of the airframes and engines.

**(9) Capital Transactions**

***Preferred Stock***

The Company is authorized to issue 5,000,000 shares of preferred stock in one or more series without shareholder approval. No shares of preferred stock are presently outstanding. The Company's Board of Directors is authorized, without any further action by the shareholders of the Company, to (i) divide the preferred stock into series; (ii) designate each such series; (iii) fix and determine dividend rights; (iv) determine the price, terms and conditions on which shares of preferred stock may be redeemed; (v) determine the amount payable to holders of preferred stock in the event of voluntary or involuntary liquidation; (vi) determine any sinking fund provisions; and (vii) establish any conversion privileges.

***Stock Compensation***

On May 7, 2019, the Company's shareholders approved the adoption of the SkyWest, Inc. 2019 Long-Term Incentive Plan, which provided for the issuance of up to 4,500,000 shares of common stock to the Company's directors, employees, consultants and advisors (the "2019 Incentive Plan"). On May 7, 2024, the Company's shareholders approved the amendment and restatement of the 2019 Incentive Plan ("Restated 2019 Incentive Plan"), providing an additional 1,298,000 shares of common stock to be issued. The Restated 2019 Incentive Plan provides for awards in the form of options to acquire shares of common stock, stock appreciation rights, restricted stock grants, restricted stock units and performance awards. The Restated 2019 Incentive Plan is subject to a fungible ratio concept, such that the issuance of stock options and stock appreciation rights reduces the number of available shares under the Restated 2019 Incentive Plan on a 1-for-1 basis, and the issuance of other awards reduces the number of available shares under the Restated 2019 Incentive Plan on a 1.65-for-1 basis. The Restated 2019 Incentive Plan is administered by the Compensation Committee of the Company's Board of Directors (the "Compensation Committee"). As of December 31, 2025, the Restated 2019 Incentive Plan had 2.8 million plan shares remaining available for future issuance, based on target payout for granted and unvested PSUs.

[**Table of Contents**](#Toc)

In 2022, the Company acquired 1,000,000 shares of common stock of Eve and a warrant giving the Company the right to acquire 1,500,000 shares of common stock of Eve at an exercise price of $0.01 per share. The Company also received a put option from an Eve shareholder for the 1,000,000 shares of common stock of Eve payable in aircraft parts credits. The intent of the put option was to reduce the Company's investment risk in Eve. The Company was restricted from selling the shares underlying the warrant until May 2025, and the warrant expires in May 2032. The Company acquired the shares of common stock, warrant and put option (collectively the "Eve Investments") for $10.0 million. The Company evaluated the Eve Investments under ASC Topic 321, "Investments – Equity Securities" and ASC Topic 815, "Derivatives and Hedging," and recorded the Eve Investments based on their pro rata share of the consideration paid using the fair value of the Eve Investments on the acquisition date, with subsequent changes in the fair value reported in earnings. During the year ended December 31, 2023, the Company sold 600,411 shares of common stock of Eve for $5.0 million, which concurrently forfeited the 600,411 shares subject to the put option from the Eve shareholder. During the year ended December 31, 2024, the Company exercised the remainder of the put option and received aircraft parts credits of $4.0 million in exchange for the 399,589 shares of common stock. At December 31, 2024, the Company's only remaining investment in Eve was the warrant to acquire 1,500,000 shares of common stock of Eve.

During the year ended December 31, 2025, the Company exercised its warrant to purchase 1,500,000 shares of common stock of Eve. The Company received 1,497,635 shares of common stock of Eve resulting from a cashless exercise. The warrant was classified as Level 3 within the fair value hierarchy ("Eve Level 3 Investment") as of December 31, 2024. The Company used the Black Scholes Option Pricing Model to determine the estimated fair market value of the Eve Level 3 Investment. Upon exercise, the Company's shares of common stock of Eve were classified as Level 1 within the fair value hierarchy as Eve's common shares are actively traded and are valued using quoted market prices.

**ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE**

None.

**ITEM 9A. CONTROLS AND PROCEDURES**

**Disclosure Controls and Procedures**

Our management, including our Chief Executive Officer and Chief Financial Officer, performed an evaluation of our disclosure controls and procedures, which have been designed to ensure that information we are required to disclose in the reports we file or submit under the Exchange Act is recorded, processed, summarized, and reported accurately and within the time periods specified in the SEC rules and forms. Our management, including our Chief Executive Officer and Chief Financial Officer, concluded that, as of December 31, 2025, those controls and procedures were effective to ensure that information we are required to disclose in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

**Changes in Internal Control**

During the most recently completed fiscal quarter, we did not make any changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**Management's Annual Report on Internal Control Over Financial Reporting**

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies may deteriorate.

Management conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2025, using the criteria issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework (2013). Based on that evaluation, management believes that our internal control over financial reporting was effective as of December 31, 2025.

The effectiveness of our internal control over financial reporting as of December 31, 2025, has been audited by Ernst & Young LLP ("Ernst & Young"), the independent registered public accounting firm who also has audited our Consolidated Financial Statements included in this Report. Ernst & Young's report on our internal control over financial reporting appears on the following page.

**Report of Independent Registered Public Accounting Firm**

To the Stockholders and the Board of Directors of SkyWest, Inc.

**Opinion on Internal Control Over Financial Reporting**

We have audited SkyWest, Inc. and subsidiaries' internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, SkyWest, Inc. and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated statements of comprehensive income, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and financial statement schedule listed in the Index at Item 15(a)2 and our report dated February 17, 2026 expressed an unqualified opinion thereon.

**Basis for Opinion**

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

**Definition and Limitations of Internal Control Over Financial Reporting**

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

A.<u>Delta Connection Program and Appointment of Delta as Agent</u>.&nbsp;&nbsp;&nbsp;&nbsp; Subject to Section 1(B) below, SKYW hereby appoints Delta as SKYW's agent to publish its fares, schedules and related information under Delta's two letter flight designator code in city pairs specified by Delta on the (i) [\*\*\*] aircraft set forth on <u>Exhibit A</u> attached hereto under the heading "Current Aircraft," (ii) any aircraft subject to the ASA Delta Connection Agreement that ASA subsequently designates as an "Aircraft" (as defined below) in accordance with the terms and conditions of the ASA Delta Connection Agreement ("ASA Aircraft") and becomes subject to this Agreement and (iii) any other aircraft subsequently agreed by the parties to be operated by SKYW ("Other Aircraft," and collectively with Current Aircraft and ASA Aircraft, the "Aircraft"), and Delta hereby accepts such appointment. Delta hereby grants SKYW the authority to operate as a Delta Connection Carrier, and SKYW hereby accepts such grant, to conduct air transportation operating the Aircraft utilizing certain services together with certain trademarks and service marks owned by Delta or which Delta has the right to use, all as provided herein.

B.<u>Aircraft Rent/Ownership Costs</u>. Prior to any aircraft other than a Current Aircraft becoming an Aircraft under the terms and scope of this Agreement, Delta shall have the right to approve the "Aircraft Rent/Ownership Cost" (as defined herein) with respect to such aircraft, such approval not to be unreasonably withheld or delayed.

Subject to the prior written consent of Delta, which shall not be unreasonably withheld or delayed, SKYW may designate and transfer, from time to time, upon the prior written consent of ASA, any Aircraft as an aircraft subject to the ASA Delta Connection Agreement to be operated thereafter by ASA pursuant to the terms and conditions thereof; <u>provided</u> that any such designation and transfer does not (i) create an undue burden on Delta, (ii) interfere with Delta's performance requirements or schedule of published flights, or (iii) otherwise increase the cost to Delta hereunder and under the ASA Delta Connection Agreement, in the aggregate. Further, subject to the prior written consent of Delta, which shall not to be unreasonably withheld or delayed, and the satisfaction of the conditions set forth in the ASA Delta Connection Agreement, SKYW, with the prior written consent of ASA, may designate and cause ASA to transfer an ASA Aircraft as an Aircraft hereunder; <u>provided</u>, <u>however</u>, that any such designation and transfer does not create an undue burden on Delta, interfere with Delta's performance requirements or schedule of published flights, or otherwise increase the cost to Delta hereunder and under the ASA Delta Connection Agreement, in the aggregate. If one or more Aircraft is

------

removed from the scope of this Agreement as provided herein or one or more aircraft are added to this Agreement pursuant to the terms of the ASA Delta Connection Agreement and this Agreement, <u>Exhibit A</u> and <u>Exhibit B</u> attached hereto shall be modified and amended to account for such aircraft removal or addition, as the case may be, subject to the mutual satisfaction of the parties hereto.

C.<u>Fares, Rules and Seat Inventory</u>. Delta, in its sole discretion, shall establish and publish all fares and related tariff rules for all seats, cargo and freight on the Aircraft, including fares and rules for local traffic in the city pairs served by such Aircraft. In addition, Delta will control all seat inventory and revenue management decisions for the Aircraft.

D.<u>Schedules Publication</u>. Delta, in its sole discretion, shall establish and publish all schedules for the Aircraft, including city-pairs served, frequencies, and timing of scheduled departures. Where practical, Delta will collaborate with SKYW to determine mutually optimal schedules. SKYW shall operate the Aircraft in the city pairs designated by Delta, subject to the frequency, scheduling and other requirements established by Delta from time to time. In addition, it is agreed and understood that Delta may utilize and schedule any of the Aircraft to perform various charter operations on behalf of Delta as can be reasonably accommodated by SKYW.

Delta will notify SKYW of schedule times, frequencies and related information for the Aircraft as sufficiently in advance of the schedule publication date so that the information can be properly disseminated to SKYW for pilot and flight attendant staffing, and related operational requirements.

<u>ARTICLE 2. EXCLUSIVITY</u>.

A.SKYW agrees that, except as otherwise directed or approved in writing by Delta, in Delta's sole discretion, (i) the Aircraft may be used only to provide the air services contemplated by this Agreement (the "Delta Connection Flights") and (ii) the Aircraft may not be used by SKYW for any other purpose including, without limitation, flying for any other airline, providing charter services other than pursuant to Section 1(D) hereof, or on SKYW's own account.

B.During the Term SKYW shall not operate more than [\*\*\*] flights per day for any third party or under any air carrier's flight designator code into or out of Atlanta (ATL), Cincinnati (CVG), Orlando (MCO) and Salt Lake City (SLC) (each, a "Restricted Airport"); <u>provided</u> that the foregoing restriction shall terminate immediately upon SKYW providing a written certification (an "Exclusivity Certificate") to Delta that SKYW is not subject to any restrictions as to where SKYW may operate for any third party or under any air carrier's flight designator code or how many flights SKYW may operate in any given airport for any third party or under any air carrier's flight designator code. Notwithstanding the above, if at any time after SKYW delivers an Exclusivity Certificate to Delta, SKYW becomes subject to any restriction as to where SKYW may operate for any third party or under any air carrier's flight designator code or how many flights SKYW may operate in any given airport for any third party or under any air carrier's flight designator code, the restrictions set forth in this paragraph shall be immediately reinstated and of full force and effect.

------

C.During the Term SKYW shall not operate more than [\*\*\*] flights per day under its own flight designator code into or out of any Restricted Airport.

D.Neither SKYW, nor any affiliate of SKYW, shall use any of the services, facilities or equipment provided by Delta, or an affiliate of Delta, to SKYW in connection with the Aircraft or the Delta Connection Flights outside the scope of this Agreement without the prior written consent of Delta. With respect to any ancillary facilities or equipment used by SKYW, or an affiliate of SKYW, in connection with providing the services contemplated by this Agreement, such use for the benefit of Delta shall have priority over any other use contemplated by SKYW, or any affiliate of SKYW. With respect to facilities or equipment owned, leased or otherwise used by SKYW, Delta shall have the right to designate from time to time which property shall be used to carry out SKYW's obligations under this Agreement; <u>provided</u>, <u>however</u>, that such request does not conflict with any other contractual obligation of SKYW then applicable.

<u>ARTICLE 3. COMPENSATION</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. <u>Compensation</u>.

In exchange for the flying and operation of the Aircraft, Delta shall pay SKYW [\*\*\*] of the "Base Rate Costs" and the "Pass Through Costs" (each as such term is defined below, and collectively, the "Direct Costs") in each case, as relates to the operation of the Delta Connection Flights and as provided for in this Agreement. It is understood that Direct Costs shall be based on market based, direct operating costs and generally accepted accounting principles ("GAAP"), but specifically shall exclude any pre-paid expenses except as expressly provided herein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)The "Base Rate Costs" shall include all direct operating costs recorded in accordance with GAAP (but specifically excluding any prepayments except as expressly provided in this Agreement and any accruals for reserve items relating to pending or threatened litigation, regulatory claims, undetermined labor rates or any other reserve item not regularly made in Operator's ordinary course of business) based upon (a) the model attached hereto as <u>Exhibit B</u> (as modified from time to time), and (b) a minimum utilization of the Aircraft of an average of [\*\*\*] block hours per day (measured on a monthly average of all of the in-revenue service Aircraft during such month) (the "Minimum Utilization Average"). If the actual utilization average is less than the Minimum Utilization Average for more than [\*\*\*] consecutive months, then the Base Rate Costs shall be subject to adjustment based on the actual utilization average. SKYW covenants and agrees that with respect to any direct operating costs only a portion of which are allocated as Base Rate Costs hereunder, such allocation shall not be made in a manner that is economically disadvantageous to Delta vis-a-vis SKYW or any other codeshare partner of SKYW to whom such direct operating costs are also allocated.

At all times during the Term, Operator shall use its best efforts to reduce its Base Rate Costs and achieve profitability improvement targets established by Delta from time to time to reduce Operator's Direct Costs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)The "Pass Through Costs" shall include the following variable costs for which Delta shall bear the risk of price and volume fluctuations; <u>provided</u> that such costs shall be reconciled on a monthly basis to reflect the actual costs incurred by Operator:

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Landing Fees;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Hull Insurance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Passenger Liability Insurance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) War Risk Insurance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) Fuel Expense – SKYW's actual fuel and into-plane expenses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) Glycol and de-icing services (but not if provided by Delta or an affiliate of Delta at no cost to SKYW);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) Catering Costs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(8) Security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(9) Property Taxes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(10) All costs to change the livery of any Aircraft pursuant to any request by Delta; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(11) Passenger amenities costs and other interrupted trip expenses, including without limitation, denied boarding compensation, food and lodging expenses and other transportation costs incurred by Operator due to any action or omission principally caused by Delta or an affiliate of Delta.

as well as the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) "Engine Maintenance Expense" – SKYW's actual engine maintenance costs incurred as provided on <u>Exhibit B</u>, or in the event SKYW enters into a "power by the hour" agreement with respect to the Aircraft engines, which agreement shall be subject to the prior written approval of Delta, the charges under such "power by the hour" agreement, less any warranty payments or credits SKYW receives. In addition, to the extent not previously reimbursed by Delta to SKYW under this Agreement or the Original Delta Connection Agreement, Engine Maintenance Expense shall include all reasonable expenses incurred by SKYW in connection with the return of the aircraft identified in paragraphs (1) and (2) of Schedule 16(B)(4) of the ASA Delta Connection Agreement together with the original engines on such aircraft at the time that SKYW originally took delivery of such aircraft, including but not limited to, costs associated with unreimbursed updates or conversion or other significant modifications of the applicable engines. Notwithstanding the foregoing, Pass Through Costs shall not include any engine maintenance performed unreasonably in advance of the time such maintenance is required in accordance with SKYW's FAA approved maintenance program for the applicable Aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) "Aircraft Rent/Ownership Costs" – SKYW's actual aircraft rent/ownership expenses for the Aircraft. Notwithstanding the foregoing, if after the Effective Date, SKYW purchases an additional Aircraft by paying the full purchase price in cash with no debt financing, the Aircraft Rent/Ownership Costs for such Aircraft shall be deemed to be the amount that would have been payable by SKYW had SKYW borrowed [\*\*\*] of such Aircraft purchase price financed at a debt rate equal to the average debt rate of the five (5) Aircraft most recently acquired by SKYW solely with debt financing during the immediately preceding 18-months; or,

------

if the foregoing is not applicable because five (5) such Aircraft have not been so acquired, a debt rate as reasonably agreed upon by the parties. SKYW shall not re- finance any Aircraft without the prior written consent of Delta if such refinancing would result in higher Aircraft Rent/Ownership Costs in the Pass Through Costs, or otherwise increase any liability or obligation of Delta.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) "Terminal Facility Rent and Use Charges" – SKYW's actual applicable terminal facility rent and use charges, including without limitation facilities maintenance and operation expenses, but excluding any such rent and use charges if premises are provided by Delta or any affiliate of Delta at no cost to SKYW. Terminal Facility Rent and Use Charges shall be reduced by any guaranty, incentive payments or rebates from any airport, local or municipal authorities Operator receives related to the Delta Connection Flights.

Notwithstanding the foregoing, Pass Through Costs shall not include any late payment charges, penalties and/or fees which SKYW incurs in connection with the payment of the expenses listed above, except to the extent such late payment charges, penalties and/or fees is attributable to any action or omission principally caused by Delta or an affiliate of Delta.

At all times during the Term, Operator shall use best efforts to control and reduce its Pass Through Costs. If Operator identifies and implements initiatives that directly result in cost savings (as compared to the previous year's Pass Through Costs adjusted for changes in volume) with respect to Pass Through Costs, Operator and Delta shall share such savings on an equal basis for a period of twelve (12) months. After such 12-month period, Delta shall retain the entire benefit of any such savings with respect to such initiatives. If Delta identifies initiatives that directly result in costs savings (as compared to the previous year's Pass Through Costs adjusted for changes in volume) by Operator with respect to Pass Through Costs, Operator shall use best efforts to implement such initiatives and Delta shall retain the entire benefit with respect to such initiatives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. <u>Non-Reimbursable Costs</u>.

The parties hereby acknowledge and agree that Operator shall be solely responsible and Delta <u>shall not</u> be responsible, nor reimburse Operator, for any of the following costs:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)any and all FAA, DOT or any other government agency fines administered or levied against Operator due to any action or omission not principally caused by Delta or an affiliate of Delta; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)Passenger amenities costs and other interrupted trip expenses, including, without limitation denied boarding compensation, food and lodging expenses and other transportation costs incurred by Operator due to any action or omission principally caused by Operator or an affiliate of Operator.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. <u>Delta Costs</u>.

------

The parties acknowledge and agree that the following costs related to SKYW's services hereunder shall be paid directly by Delta and shall not be included in the Direct Costs:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Travel agency commissions, if any;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Credit card fees;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Reservations handling charges;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) Booking fees;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) Frequent flyer charges;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) Denied boarding costs, except as set forth in Section 3(C)(3) above,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) Advertising;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(8) Glycol and de-icing services (if provided by Delta or an affiliate of Delta);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(9) Terminal Facility Rent and use charges, including without limitation facilities maintenance and operations costs (if premises are provided by Delta or an affiliate of Delta); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(10) The cost of any Support Services (as defined herein) and any ticketing services, if provided by Delta or an affiliate of Delta.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. <u>Block Hour Payment</u>.

In addition to the payment by Delta of Direct Costs, Delta shall pay Operator an amount equal to [\*\*\*] per block hour, subject to an annual escalation of [\*\*\*] ("Block Hour Payment").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. <u>Accounting Provisions</u>.

Delta shall retain all revenues (including, without limitation, passenger, cargo, mail, food, beverage and duty-free services or any other revenue including, without limitation, any guaranteed or incentive payments from airport, local or municipal authorities in connection with scheduling flights to such airport or locality or any federal funds payments) in connection with the operation of the Delta Connection Flights. Operator shall promptly remit to Delta all monies with respect to all airline ticket sales, on-board sales, baggage charges, passenger charges, cargo sales and all other revenue collected by SKYW or any agent or employee of SKYW in connection with the operation of the Aircraft (including credit card transactions).

On the [\*\*\*] day of each month (or if not a business day, on the following business day) Delta will advance to SKYW via wire transfer [\*\*\*] of the estimated monthly Direct Costs and Block Hour Payment (each, a "Provisioning Payment"). SKYW shall calculate the amount of the advance, using projected fuel costs, estimated number of weekly revenue block hours, departures and passengers based on the most recent Delta schedule for the Delta Connection Flights and assuming SKYW's actual completion rate will be equal to [\*\*\*] and SKYW shall submit a written invoice (together with the estimates and calculation referenced in the prior sentence) to Delta no later than the [\*\*\*] day of the preceding month (or if not a business day, on the following business day). Delta shall be entitled to review and verify SKYW's invoice and accompanying estimates and calculations prior to making any advance payment pursuant to this paragraph; <u>provided</u>, <u>however</u>, any such review or payment by Delta shall not be deemed as Delta's final approval of SKYW's invoice and accompanying estimates and calculations, and such information shall still be subject to potential audit and reconciliation pursuant to this Article

------

3; <u>provided</u>, <u>further</u>, Delta's review of any invoice and accompanying estimates and calculations shall not extend beyond the due date of the first payment for the month at issue.

Nothing in this Agreement shall relieve Delta or Operator of any of their respective obligations under the Original Delta Connection Agreement arising prior to the Effective Date. [\*\*\*].

Within [\*\*\*] days following the end of each month and upon the termination of this Agreement, SKYW will reconcile the actual Direct Costs and Block Hour Payment earned by SKYW for the Delta Connection Flights and the final operating results of, and actual revenue block hours flown by, SKYW with the Provisioning Payments made as described above and submit a final written invoice (together with the relevant data with respect to the actual Base Rate Costs and Block Hour Payment earned and final actual operating results) to Delta; provided, however, that for the month of the Term that includes the Effective Date, such reconciliation shall include the reconciliation of amounts paid as described in the immediately preceding paragraph. Within [\*\*\*] business days of receipt of such invoice, Delta will review and verify such final invoice and data, and Delta or Operator, as the case may be, shall pay, via wire transfer, to an account designated by the other party, monies equal to the agreed to reconciled amount. Delta shall be entitled to review and verify SKYW's final written invoice (together with the relevant data with respect to the actual Base Rate Costs and Block Hour Payment earned and final actual operating results); <u>provided</u>, <u>however</u>, any such review or payment shall still be subject to potential audit and reconciliation pursuant to this Article 3. With respect to a reconciliation upon a termination of this Agreement that is not effective at the end of a calendar year, Direct Costs which are paid on an annual basis shall be allocated on a pro rata basis assuming a 365 day calendar year. Further, with respect to Pass Through Costs associated with engine maintenance and overhauls, upon termination of this Agreement, such Pass Through Costs shall be calculated by multiplying the number of engine block hours flown since the last engine overhaul by an engine block hour rate reasonably determined, in good faith, by the parties. Upon such calculation, Delta shall, at its sole option, either (i) pay such calculated amount to SKYW as part of the final reconciliation, (ii) perform (or have a third party perform) the requisite engine maintenance or overhauls or (iii) a combination of (i) and (ii).

Notwithstanding anything herein to the contrary, if SKYW is unable to operate any of the Aircraft, or any of the Delta Connection Flights, due to a strike, labor dispute, work stoppage or similar event or any other event; <u>provided</u> in each such case that such event is substantially within the control of, or caused by, some action or inaction of SKYW or an affiliate of SKYW or relates to the Aircraft, Delta shall not be obligated to pay SKYW any Direct Costs, Block Hour Payment, or any other amounts, in connection with such non-operated Aircraft and Delta Connection Flights. However, if SKYW is unable to operate any of the Aircraft, or any of the Delta Connection Flights, due to a strike, labor dispute, work stoppage, or similar event or any other event, that is substantially within the control of, or caused by, some action or inaction of Delta or an affiliate of Delta, Delta shall be obligated to pay SKYW Direct Costs and Block Hour Payments based on the Minimum Utilization Average. If SKYW is unable to operate any of the Aircraft, or any of the Delta Connection Flights, due to an event that is not substantially within the control of, or caused by, some action or inaction of either SKYW or Delta, Delta shall be obligated to pay SKYW's Fixed Costs on <u>Exhibit B</u> attached hereto, as well as crew costs

------

(provided SKYW shall use best efforts to mitigate and minimize such crew costs in a commercially reasonable manner), Aircraft Rent/Ownership Costs, hull insurance, property taxes and heavy inspection costs for maintenance already in process prior to any such event, but not any other variable costs or Block Hour Payment with respect to such non-operated Aircraft and Delta Connection Flights during the period that SKYW is unable to operate such Aircraft or the Delta Connection Flights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. <u>Audit of Costs, Operations and Service Levels</u>.

Operator shall maintain complete and accurate books and records to support and document all revenues, costs and expenses related to the Aircraft and its Delta Connection Program operations hereunder in accordance with GAAP. Delta's in-house finance staff and any independent consultants selected by Delta shall be entitled, following reasonable notice to Operator, to audit and inspect Operator's books and records with respect to services provided hereunder, the service levels achieved, and the determination of charges due pursuant to this Agreement for the purpose of (i) prospectively adjusting the Base Rate Costs in connection with any annual review pursuant to Section 3(G) hereof or (ii) auditing Direct Costs or Block Hour Payment due or paid hereunder. Any such audit will be conducted during regular business hours and be paid for by Delta unless such audit determines that Operator owes Delta in excess of [\*\*\*] then Operator shall pay Delta the costs and expenses incurred by Delta in connection with such audit.

G.<u>Rate Setting</u>. The parties agree that on or after [\*\*\*], 2010, but in no event later than [\*\*\*], 2010 (and each 5 years thereafter on the same applicable dates), the parties shall reset the Base Rate Costs to reflect Operator's actual Base Rate Costs for 2010 (and each 5th year thereafter) and amend <u>Exhibit B</u>. In the event that the parties are unable to agree on the reset Base Rate Costs, the parties further agree that (i) at the request of either party, and at the expense of the requesting party, the parties shall engage a mutually agreed independent consultant, to determine the reset Base Rate Costs. Any such determination by the independent consultant shall be binding on and implemented by the parties. Until the parties are able to agree upon the reset Base Rate Costs to be set forth in <u>Exhibit B</u> (or such are determined by the independent consultant), the Base Rate Costs of the year immediately prior to the reset year shall govern until such time as the parties agree upon the reset Base Rate Costs. Upon agreement, the reset Base Rate Costs and the provisions of <u>Exhibit B</u> as so amended shall be applied retroactively to the beginning of the reset period for which the amendment applies. The Base Rate Costs will apply for all Delta Connection Flights during the year applicable to such Base Rate Costs, and Operator will bear any risks of additional expenses not reflected therein. Operator will use its best efforts to minimize its costs to operate the Aircraft in accordance with this Agreement, and Operator and Delta each agree to notify the other as soon as reasonably practicable of any anticipated or potentially substantial change of cost or operational performance.

H.<u>Right of Set-off</u>. Delta may offset against the next scheduled payment(s) to be made pursuant to Section 3(E) above (i) the undisputed amount of any payment that SKYW or an affiliate of SKYW owes to Delta or an affiliate of Delta but has not made when due or (ii) if SI fails to deposit the applicable Deposit Amount (as defined in Schedule 2.01 of the Purchase Agreement), on any Deposit Date (as defined in Schedule 2.01 of the Purchase Agreement) an

------

amount up to the applicable Deposit Amount and (iii) if SI fails to pay the Top-Up Amount (as defined in Schedule 2.01 of the Purchase Agreement) when due and payable, an amount up to the Top-Up Amount. SKYW may offset against a payment due Delta pursuant to Section 3(E) above the undisputed amount of any payment that Delta or an affiliate of Delta owes to SKYW or an affiliate of SKYW but has not made when due. If a party makes a corrective payment after the other party has exercised its right of offset with respect to such corrective payment, such offset shall be reversed in the next scheduled payment from the other party to such party having made the corrective payment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I. <u>Pro Rate Resolution</u>.

[\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)The Prorate Dispute Resolution Committee shall use all reasonable efforts to resolve the Dispute. In the event that the Prorate Dispute Resolution Committee does not reach consensus within thirty days following the Effective Date, then the parties may agree between themselves to utilize such form of third party mediation as may be agreed between such parties, such mediation to be carried out on such basis as may be agreed between the parties. If the parties in dispute do not agree to go to mediation, the Dispute will be subject to arbitration under the following provisions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)Unless otherwise agreed, if the Dispute is not resolved within sixty days following the Effective Date, it shall be referred to and settled by binding and confidential arbitration according to and in accordance with the American Arbitration Association ("AAA") Commercial Arbitration Rules (the "Arbitration Rules"), which Arbitration Rules are deemed to be incorporated by reference herein, except as they may be modified herein or by mutual agreement of the parties. In the event of a conflict between the Arbitration Rules and the provisions of this Agreement, the provisions of this Agreement shall prevail.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4)The arbitration, including the rendering of the award, shall be conducted by three (3) arbitrators; <u>provided</u>, <u>however</u>, that the arbitration may be conducted by only one (1) arbitrator if the parties so agree in advance of the arbitration and are able to agree upon a single, mutually acceptable individual. A party initiating the arbitration (the "Claimant") shall appoint an arbitrator in its request for arbitration (the "Request"). The other party (the "Respondent") shall appoint an arbitrator within thirty (30) days of receipt of the Request and shall notify the Claimant of such appointment in writing. If within thirty (30) days of receipt of the Request by the Respondent, the Respondent has not appointed an arbitrator, then that arbitrator shall be appointed by the AAA. The first two (2) arbitrators appointed in accordance with this provision shall appoint a third arbitrator within thirty (30) days after the Respondent has notified the Claimant of the appointment of the Respondent's arbitrator or, in the event of a failure by the Respondent to appoint, within thirty (30) days after the AAA has notified the parties (and any arbitrator already appointed) of its appointment of an arbitrator on behalf of the Respondents. When the third arbitrator has accepted the appointment, the two (2) arbitrators making the appointment shall promptly notify the parties of the appointment. If the first two (2) arbitrators appointed fail to appoint a third arbitrator or to so notify the parties within the time period prescribed above, the AAA shall appoint the third arbitrator and shall promptly notify the parties

------

of the appointment. The third arbitrator shall act as chairman of the arbitration tribunal (in accordance with the Arbitration Rules). Each of the arbitrators shall be, to the extent appropriate, knowledgeable about the marketing and financial settlement aspects of the airline industry (and provided that such persons are then available) and fluent in the English language. If a party does not object to an arbitrator within seven (7) days of appointment, such arbitrator shall be conclusively presumed to have such qualifications. The arbitrator(s) shall be appointed in accordance with the Arbitration Rules. The arbitration proceedings shall take place in New York, New York, or other location as mutually agreed by the parties, and shall be conducted in the English language; <u>provided</u> that all translation costs relating to documentation required in the proceedings shall be shared equally between the parties no matter what the outcome of the arbitration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5)Unless a party challenges the appointment of any arbitrator, the parties agree to use all reasonable endeavors to complete the arbitration within 60 days commencing from the date the last arbitrator accepts his or her appointment. In the event of a challenge, the 60 day period shall begin to run from the date the AAA resolves the challenge and, if necessary, appoints another arbitrator. Any decision or award of the arbitrator(s) shall be based solely on the terms of this Agreement, the Prorate Agreement, the evidence submitted by the parties and/or obtained by the arbitrator(s) in accordance with the Arbitration Rules and the substantive governing law applicable to the Prorate Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6)The parties waive any right to appeal the arbitration award, to the extent a right to appeal may be lawfully waived. Each party retains the right to seek judicial assistance: (a) to compel arbitration; (b) to obtain interim measures of protection pending arbitration; and (c) to enforce any decision of the arbitrator, including the final award.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7)The Disputes will be arbitrated with each party submitting its version of a proposed resolution and the arbitrator choosing one or the other as the most appropriate resolution.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(8)Any payment required to be made hereunder shall be paid within 5 days of resolution of the Dispute and if any payment is required to be made by Delta in connection therewith, such payment shall be made through the Clearing House.

<u>ARTICLE 4. TICKETING SERVICES; SIGNAGE; FACILITIES; SLOTS AND ROUTES</u>.

A.<u>Ticketing Services</u>. Either Delta or Operator will provide primary airport ticketing services in connection with the Delta Connection Flights, and, if applicable, the other party will provide supplemental ticketing services for the Delta Connection Flights at Delta's airport ticketing locations and will use Delta ticket stock for such purposes.

B.<u>Signage</u>. Unless otherwise agreed by the parties, Delta will design, provide and pay for appropriate airport and other signage installed after the Effective Date to reflect the Delta Connection Flights and the relationship between SKYW and Delta. The nature and type of such signage will be in the sole discretion of Delta, subject to any airport, governmental or quasi- governmental restrictions or requirements. Delta will be responsible for installing and

------

maintaining all such signage, but the parties will mutually determine which party will obtain any necessary formal or informal approvals from appropriate airport or other authorities to install such signage.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)In connection with the Delta Connection Flights, SKYW shall use the gates and facilities designated by Delta from time to time at the locations in which SKYW operates such Delta Connection Flights, and, except for gates and facilities used by SKYW for both Delta Connection Flights and its United Express service as of the Effective Date, no other use of such gates and other facilities by SKYW or parties other than Delta or Delta's designee shall be allowed without Delta's express written consent.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)Delta may, at its option, elect to enter into a lease, sublease, permit, license or other agreement in lieu of SKYW entering into such agreement for any facilities to be used by SKYW at any new or existing city to be served by SKYW pursuant to this Agreement, and in the event Delta exercises this option (i) Delta shall enter into a lease, sublease, permit, license or other agreement with the lessor of such facilities, (ii) SKYW shall utilize such facilities pursuant to a sublease, license agreement, permit, facilities use agreement or ground handling agreement with Delta as Delta elects, (iii) at Delta's option, the sublease, license agreement, permit, facilities use agreement or ground handling agreement shall terminate when SKYW ceases to operate Delta Connection Flights at the airport and as otherwise provided in such agreement, sublease or permit, and (iv) Delta shall enter into agreements for facilities which are reasonably suitable for SKYW's operational needs. Delta's right to designate gates and other facilities to be used by SKYW in connection with providing Delta Connection Flights shall include the right at each airport, in Delta's discretion, to either: (a) provide for use of some or all of the needed facilities to SKYW through mutually acceptable subleases, license agreements, permits, facilities use agreements or ground handling agreements; or (b) require SKYW to obtain use of such facilities from the airport operator or other lessors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5)Provided that at time of any proposed assignment, transfer, sublease, alteration, amended, modification or termination of a "Delta Connection Gate Lease" as defined below such Delta Connection Gate Lease is then used by SKYW in connection with Delta Connection Flights, SKYW shall not assign, transfer, sublease or materially alter, amend, or modify or terminate any Facilities Lease, any other lease, sublease, permit, license and other use agreement of airport facilities being used in connection with Delta Connection Flights, or any master lease superior thereto (each a "Delta Connection Gate Lease" and collectively, the "Delta Connection Gate Leases") to which it is a party without the prior written consent of Delta.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6)At any location in which SKYW is the signatory carrier of the applicable Delta Connection Gate Lease, SKYW shall vote as directed in writing by Delta on any matters submitted to the signatory carriers for a vote.

<u>ARTICLE 11. TERM AND TERMINATION</u>.

A.This Agreement is effective as of the Effective Date and shall continue until the fifteenth (15th) anniversary of such date (such period, and any extension or renewal thereof, the "Term"). At the end of such initial fifteen-year term, Delta shall have the right to extend the term of this Agreement for up to four (4) additional five (5) year terms (each, an "Extension Term") on the same terms and conditions (as amended from time to time in accordance with this Agreement) of this Agreement. To exercise its right to extend the initial term or an Extension Term, as the case may be, Delta shall provide SKYW with written notice of such extension not later than 180 days prior to the end of the initial term or Extension Term that is, at the time of such notice, in force. In the event of a "Merger" (as defined below) or "Change of Control" (as defined below) of SKYW or SI, Delta shall have the right to either (i) add two (2) additional Extension Terms on the same terms and conditions (as amended from time to time in accordance with this Agreement) as provided in this Agreement, or (ii) terminate this Agreement in accordance with Section 11(E)(1) below, by written notice to SKYW within the later of 180 days of the Merger or Change of Control.

B.Notwithstanding the provisions of Section 11(A), either party may terminate this Agreement immediately if the other party files a voluntary petition in bankruptcy, makes an assignment for the benefit of creditors, fails to secure dismissal of any involuntary petition in bankruptcy within sixty (60) days after the filing thereof, or petitions for reorganization, liquidation, or dissolution under any federal or state bankruptcy or similar law.

C.Notwithstanding the provisions of Section 11(A), in the event of a material breach of this Agreement by either party remaining uncured for more than [\*\*\*] days after receipt of written notification of such breach by the nonbreaching party, then the nonbreaching party may immediately terminate this Agreement at its sole option; <u>provided</u>, <u>however</u>, that if the breaching party shall have commenced to cure any such material breach, and, notwithstanding the reasonable diligence of the breaching party in attempting to cure such failure, such failure is not cured within said [\*\*\*] period but is curable with future due diligence, there shall exist no cause for termination so long as the breaching party is proceeding with due diligence to cure such failure and shall in fact cure such failure within [\*\*\*] following such notice.

D.(1)If either party reasonably believes that there is a substantial likelihood of an occurrence of a "Force Majeure Event" (as defined in Article 21) in the near term, upon notice from such party to the other party, the parties shall meet and mutually develop a preemptive strategy to manage and mitigate the risks and expenses expected to be incurred as a result of such Force Majeure Event, including, without limitation, adjusting the schedule of Delta Connection Flights scheduled at such time. The parties covenant and agree to implement such mutually developed strategy. Delta shall reimburse SKYW for the reasonable costs incurred by SKYW as a result of SKYW's participation in the implementation of such strategy in accordance with the terms of Article 3 of this Agreement.

------

If Delta is the non-affected party, Delta shall notify ASA of Delta's strategy to mitigate the financial impact to Delta of the Force Majeure Event (the "Delta Notice"). If such strategy includes the transfer or reallocation of some or all of the Delta Connection Flights operated by SKYW, ASA shall have a right of first refusal to operate some or all of such Delta Connection Flights, provided ASA must affirmatively exercise such right of refusal by notifying Delta of such election in writing within twenty-four (24) hours of ASA receiving the Delta Notice (the "ASA Affirmative Notice"). If Delta does not receive an ASA Affirmative Notice within such 24-hour period, ASA shall be deemed to have not exercised its right of first refusal to operate such Delta Connection Flights. ASA's right of first refusal shall be subject to (i) ASA being a Delta Connection Program operator at the time of such Force Majeure Event occurring and (ii) ASA being able to operate the transferred Delta Connection Flights in a time period acceptable to Delta. All flying by ASA of such transferred Delta Connection Flights shall be flown pursuant to the terms and conditions of the ASA Delta Connection Agreement.

If SKYW is the non-affected party, SKYW shall notify Delta of SKYW's strategy to mitigate the financial impact to Delta of the Force Majeure Event.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)Upon the termination of a Force Majeure Event, Delta and SKYW (and ASA if necessary, which SKYW shall cause) shall meet and develop an orderly transition plan to restore the Delta Connection Flights operated by SKYW prior to such Force Majeure Event (a "Restoration Plan"). Such Restoration Plan shall take into account, without limitation, the operational needs and capabilities of each party, the impact on Delta customers and the cost to each of the parties, and shall further include a reasonable time period by which the SKYW Exclusivity Covenant shall each be reinstated. The parties covenant and agree to implement such Restoration Plan. With respect to the costs incurred by each of SKYW and Delta in connection with the implementation of a Restoration Plan (respectively, "Restoration Costs"), (i) if Delta is the non-affected party, SKYW shall be responsible for, and Delta shall have no obligation to reimburse SKYW for, each of Delta's and SKYW's Restoration Costs and (ii) if SKYW is the non-affected party, Delta shall be responsible for each of Delta's and SKYW's Restoration Costs.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)Notwithstanding the provisions of Section 11(A), (B), (C) and (D), SKYW shall have the right to terminate this Agreement immediately and at its sole option if ASA has the right to terminate the ASA Delta Connection Agreement.

F.<u>Partial Termination</u>. Notwithstanding anything herein to the contrary, effective at any time after the tenth (10th) anniversary of the Effective Date, Delta shall have the right to remove from the scope of this Agreement each Aircraft effective upon the date that the lease, mortgage or other financing arrangement with respect to such Aircraft in effect as of the Effective Date expires by providing SKYW with at least eighteen (18) months' prior written notice. If Delta so removes an Aircraft from the scope of this Agreement as provided in this Article 11(F) ("Removed Aircraft") and if Delta has in place at any time during the period commencing on the notice date and ending on the date of actual removal of the Aircraft from the scope of this Agreement an announced committed fleet growth plan or a request for proposal for additional regional aircraft operation under the Delta Connection Program ("Growth Aircraft"), then during such period Delta agrees to offer to SKYW the opportunity to bid on such Growth Aircraft to the extent of the Removed Aircraft (not to exceed the regional aircraft available). If SKYW is not awarded a portion of the Growth Aircraft so as to replace the Removed Aircraft, SKYW shall be offered the opportunity to match the "Winning Bid" (as defined below) with respect to the economic terms and conditions (including, without limitation, Direct Costs and Block Hour Payment, but excluding extraordinary economic terms such as an upfront buy-down payment from the operator to Delta). If SKYW in good faith (i) participates in the bid for Growth Aircraft and (ii) decides to attempt to match the economic terms and conditions of the Winning Bid and provides Delta with prompt written notice of such decision, then Delta shall provide SKYW with a certificate that sets forth the pertinent economic terms and conditions of the Winning Bid. If SKYW elects to match the Winning Bid, Growth Aircraft shall be added to the scope of this Agreement (as modified with respect to such additional

aircraft to account for the economic terms and conditions of the Winning Bid with respect to such regional aircraft) so as to replace the Removed Aircraft. For purposes of this Agreement, a "Winning Bid" means a bona fide bid of a third party to whom Delta in good faith intends to award the additional Delta Connection Program regional aircraft subject to the announced committed fleet plan or request for proposal.

G.Termination of this Agreement for any reason shall not relieve either party of rights and obligations incurred prior to the effective date of termination. A party's right to terminate this Agreement shall be in addition to any other rights or remedies, in law or equity, available to such party.

H.If any foreign route authority is removed from SKYW as a result of the ASA Acquisition, such loss of route authority shall not be a breach of this Agreement by SKYW, and following such loss Delta will reschedule the Aircraft operating such lost route.

WHEREAS, the parties desire to amend certain provisions of the Agreement; and

NOW, THEREFORE, for and in consideration of the mutual undertakings set forth herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Delta and SKYW, intending to be legally bound, hereby agree to amend the Agreement as follows:

[\*\*\*]

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)&nbsp;&nbsp;&nbsp;&nbsp;Upon receipt of a Removal Notice as to any CRJ-200 Aircraft, Operator in its sole discretion may elect to operate, in accordance with the terms and conditions of this Agreement, in replacement of such CRJ-200 Aircraft a regional jet configured with at least [\*\*\*] passenger seats but no more than [\*\*\*] passenger seats (each a "Replacement Aircraft"), provided, (x) Operator shall use commercially best efforts to ensure such Replacement Aircraft shall be available to be placed into service within the Delta Connection Program by the lease expiration date of the applicable CRJ-200 Aircraft, but in any event no later than [\*\*\*] after such lease expiration date and [\*\*\*].

In the event Operator elects to exercise its right of replacement, such election shall be binding and irrevocable. If Operator elects not to exercise its right of replacement with respect to any CRJ-200 Aircraft, such CRJ-200 Aircraft shall be removed and not be replaced hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv)&nbsp;&nbsp;&nbsp;&nbsp;The replacement rights provided for Operator in Section 11(F)(2)(ii) above shall not apply with respect to [\*\*\*] CRJ-200 Aircraft removed from this Agreement as provided in this Section 1l(F)(2) above.

**AMENDMENT NUMBER THREE to**

**AMENDED AND RESTATED DELTA CONNECTION AGREEMENT**

This Amendment Number Three (this "Amendment"), effective as of the 1st day of July, 2009 (the "Amendment Number Three Effective Date"), to the Amended and Restated Delta Connection Agreement dated and effective September 8, 2005 (as amended from time to time, the "Agreement"), is between Delta Air Lines, Inc., 1030 Delta Boulevard, Atlanta, Georgia 30320 ("Delta"), and SkyWest Airlines, Inc. ("SKYW" or "Operator"), 444 South River Road, St. George, Utah 84790.

WHEREAS, Delta and SKYW are parties to the Agreement; and

WHEREAS, the parties desire to amend certain provisions of the Agreement.

NOW, THEREFORE, for and in consideration of the mutual undertakings set forth herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Delta and SKYW, intending to be legally bound, hereby agree to amend the Agreement as follows:

**1.** **Defined Terms.** All capitalized terms used but not defined herein shall have the meaning ascribed to such terms in the Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;**2.** **Minimum Utilization Average .** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Effective as of the Amendment Number Three Effective Date, Article 3.A.(i) of the Agreement is hereby amended by deleting the following text from the first paragraph of such article:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) a minimum utilization of the Aircraft of an average of [\*\*\*] block hours per day (measured on a monthly average of all of the in-revenue service Aircraft during such month) (the "Minimum Utilization Average"). If the actual utilization average is less than the Minimum Utilization Average for more than [\*\*\*], then the Base Rate Costs shall be subject to adjustment based on the actual utilization average.

and replacing such text with the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) a minimum utilization of the Aircraft (the "Monthly Minimum Utilization Target") as calculated, with respect to a particular month, using the following formula:

[\*\*\*]

Where:

[\*\*\*]

------

**EXECUTION VERSION**

If the actual monthly scheduled block hours of the Aircraft is less than the Monthly Minimum Utilization Target [\*\*\*] for more than [\*\*\*], then the respective actual scheduled block hours [\*\*\*] for each of the current and prior [\*\*\*] shall be subtracted from the respective Monthly Minimum Utilization Target [\*\*\*] for such [\*\*\*] and such difference shall be multiplied by the applicable Base Rate Costs per block hour in effect for the applicable month with respect to the CRJ200 Aircraft [\*\*\*] (each such difference, a "Monthly Shortfall" (G)). The Monthly Shortfalls of the current and prior [\*\*\*] shall then be summed and such amount shall then be divided by [\*\*\*] to determine the current month's minimum utilization payment due to Operator from Delta (a "Minimum Utilization Payment" [\*\*\*]). Any Minimum Utilization Payment shall be due to Operator on the next monthly invoice reconciliation payment after the month for which the Minimum Utilization Payment was calculated, and such Minimum Utilization Payment shall be deemed for all purposes of the Agreement a Base Rate Cost for the month for which the Minimum Utilization Payment was calculated.

An example of a Minimum Utilization Payment calculation is set forth on Exhibit B attached hereto. The parties acknowledge that although the Monthly Minimum Utilization Target is calculated on the entire fleet of Aircraft subject to the Agreement, only the Base Rate Costs per block hour with respect to the CRJ200 Aircraft are used to calculate the Monthly Shortfall, if any.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. Effective as of the Amendment Number Three Effective Date, the term "Minimum Utilization Average" used in Article 3.E of the Agreement is replaced with the term "Monthly Minimum Utilization Target."

&nbsp;&nbsp;&nbsp;&nbsp;**3.** **Miscellaneous .** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A.This Amendment constitutes the entire understanding of the parties with respect to the subject matter hereof, and any other prior or contemporaneous agreements, whether written or oral, are expressly superseded hereby.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B.The Amendment may be executed in any number of counterparts, including via facsimile, each of which shall be deemed an original and all of which, taken together, shall constitute one and the same instrument.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C.Except as specifically stated herein, all other terms and conditions of the Agreement shall remain in full force and effect. In the event of any conflict between the terms of this Amendment and the Agreement, the terms of this Amendment shall prevail. Except as expressly modified, nothing in this Amendment shall be construed as a waiver of any rights under the Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D.The parties hereto, together with Atlantic Southeast Airlines, Inc. ("ASA") are parties to that certain lawsuit styled Atlantic Southeast Airlines, Inc. and SkyWest Airlines, Inc. v. Delta Air Lines, Inc. in the Superior Court of Fulton County, State of Georgia, Civil Action File Number 2008CV145995 (the "Lawsuit"). Each party to this Amendment enters this Amendment with a full reservation of rights under the Agreement and the Lawsuit and nothing

**AMENDED AND RESTATED DELTA CONNECTION AGREEMENT**

This Amendment Number Four (this "Amendment"), effective as of November 19, 2010, to the Amended and Restated Delta Connection Agreement dated and effective September 8, 2005 (as amended from time to time, the "Agreement"), is between Delta Air Lines, Inc., 1030 Delta Boulevard, Atlanta, Georgia 30320 ("Delta"), and SkyWest Airlines, Inc. ("SkyWest" or "Operator"), 444 South River Road, St. George, Utah 84790.

WHEREAS, Delta and SkyWest are parties to the Agreement; and

WHEREAS, the parties desire to amend certain provisions of the Agreement and to document certain other agreements of the parties, on the terms and conditions set forth herein; and

NOW, THEREFORE, for and in consideration of the mutual undertakings set forth herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Delta and SkyWest, intending to be legally bound, hereby agree to amend the Agreement as follows:

**Article 1: Defined Terms**

All capitalized terms used but not defined herein shall have the meaning ascribed to such terms in the Agreement.

**Article 2: Base Rate Costs for Period between [\*\*\*] Anniversary of Effective Date and [\*\*\*]**

Notwithstanding the provisions of [\*\*\*] the Agreement, the parties agree that for the period beginning on the [\*\*\*] anniversary of the Effective Date and ending on [\*\*\*], Operator's Base Rate Costs shall be as set forth on <u>Exhibit 2</u> attached hereto and incorporated herein. [\*\*\*].

**Article 3: Base Rate Costs for Period between [\*\*\*] Anniversary of Effective Date and [\*\*\*]**

Notwithstanding the provisions of Sections 3.G. [\*\*\*] of the Agreement, the parties agree as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. For the period beginning [\*\*\*] through and including [\*\*\*] and for calendar years [\*\*\*], Operator's respective Base Rate Costs shall be as set forth on <u>Exhibit 3</u> attached hereto and incorporated herein. [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. In consideration of the establishment of the rates for the Base Rate Costs through calendar year [\*\*\*] as set forth in this Articles 2 and 3 of this Amendment, Delta hereby waives its right to terminate the Agreement pursuant to [\*\*\*] for the period beginning on the [\*\*\*] anniversary of the Effective Date and ending on [\*\*\*] (the "Waiver Period"). The parties acknowledge and agree, however, that such waiver

------

provided by Delta is for a limited duration and that the rights and obligations of the parties set forth in [\*\*\*] of the Agreement shall remain in full force and effect after the conclusion of the Waiver Period with respect to the remainder of the Term following the Waiver Period. [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. The parties agree that on or after [\*\*\*], but in no event later than [\*\*\*], the parties shall reset the Base Rate Costs to reflect Operator's actual Base Rate Costs for [\*\*\*] in accordance with the terms, conditions and procedures set forth in Section 3.G. of the Agreement (as modified from time to time). In connection with such reset of the Base Rate Costs, the parties shall use the Operator's actual direct operating costs recorded in accordance with GAAP for the twelve month period ended [\*\*\*] as a baseline and adjusted for reasonably foreseeable changes in Operator's operating costs, [\*\*\*]. The parties agree that if Operator's Base Rate Costs accounting for Operator's crew rates and productivity are reduced pursuant to [\*\*\*], such reduction shall only apply to the Base Rate Costs accounting for Operator's crew rates and productivity in effect for the calendar year of the effective date of such reduction of the Base Rate Costs accounting for Operator's crew rates and productivity; [\*\*\*]. The parties acknowledge and agree that the reset of Operator's Base Rate Costs contemplated by this Section 3.c. shall not apply to the [\*\*\*] "CRJ-900 Replacement Aircraft" (as such term is defined in Amendment Number Two to the Agreement dated as of January 1, 2008 ("Amendment Number 2")) in accordance with Section 3.F.(i) of Amendment Number 2.

**Article 4: Pass Through Cost Savings**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Delta shall pay Operator an amount of [\*\*\*] as full and final payment for Operator's portion of cost savings initiatives with respect to Pass Through Costs through the date of this Amendment pursuant to the last paragraph of Section 3.A.(ii) of the Agreement. The parties agree that upon such payment from Delta to Operator, no party shall owe the other party any further amounts pursuant to the last paragraph of Section 3.A.(ii) of the Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. The following sentences shall be deleted in their entirety from the last paragraph of Section 3.A.(ii) of the Agreement:

"If Operator identifies and implements initiatives that directly result in cost savings (as compared to the previous year's Pass Through Costs adjusted for changes in volume) with respect to Pass Through Costs, Operator and Delta shall share such savings on an equal basis for a period of [\*\*\*]. After such [\*\*\*] period, Delta shall retain the entire benefit of any such savings with respect to such initiatives."

**Article 5: Treatment of Engine Maintenance and Overhaul Pass Through Costs upon Termination of the Agreement**

Each party hereby covenants and agrees to negotiate in good faith with the other party an amendment and/or modification to the Agreement with respect to the determination and payment of Pass Through Costs associated with engine maintenance and overhauls upon

------

termination of the Agreement as currently contemplated in the last two sentences of the fourth paragraph of Section 3.E. of the Agreement. The parties acknowledge and agree that it is their mutual intent to amend and/or modify the Agreement to ensure that such Pass Through Costs are equitably determined, allocated and paid among the parties with no undue financial advantage or benefit to either party considering, without limitation, the following factors: engine usage during the term of the Agreement, required return conditions of the engines, engine block hours flown since the last engine overhaul and the remaining useful life of the engine following the expiration of the Agreement.

**Article 6: Miscellaneous**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. This Amendment constitutes the entire understanding of the parties with respect to the subject matter hereof, and any other prior or contemporaneous agreements, whether written or oral, are expressly superseded hereby:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. The Amendment may be executed in any number of counterparts, including via facsimile, each of which shall be deemed an original and all of which, taken together, shall constitute one and the same instrument.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. Except as specifically stated herein, all other terms and conditions of the Agreement shall remain in full force and effect. In the event of any conflict between the terms of this Amendment and the Agreement, the terms of this Amendment shall prevail.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d. The parties hereto, together with Atlantic Southeast Airlines, Inc. ("ASA") are parties to that certain lawsuit styled Atlantic Southeast Airlines, Inc. and SkyWest Airlines, Inc. v. Delta Air Lines, Inc. in the Superior Court of Fulton County, State of Georgia, Civil Action File Number 2008CV145995 (the "Lawsuit").

time of the accomplishment of the relevant maintenance task or modification, as the case may be.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;N. <u>Replacement Engines.</u> Delta shall replace any "Lost Engine" (as defined in this Section 5(N)) as prescribed in this Section 5(N). A "Lost Engine" means a CRJ- 700 Additional Aircraft Engine or a CRJ-900 Tranche 1 Additional Aircraft Engine which is leased under a separate, stand alone engine lease agreement and is either (i) the subject of an "event of loss" (under and as such term is defined in the lease for such engine between Delta (or an affiliate of Delta) and SkyWest or XJet, as applicable) and which is fully insured at the time of such loss as required by the lease for such engine between Delta (or an affiliate of Delta) and SkyWest or XJet, as applicable, or (ii) subject to a lease or sublease described in Section 5(G) above which is terminated due to any action or inaction of Delta or any affiliate of Delta, in each case in its capacity as lessor, and which is not attributable to an event of loss of such engine or any action or inaction of SkyWest or XJet, as applicable, in each case, in their capacity as lessee. Delta shall replace any Lost Engine arising from an event of loss within [\*\*\*] after Delta's (or its affiliate's) receipt of the full amount of the required insurance proceeds stipulated in the lease for such Lost Engine, and, for any other Lost Engine, within [\*\*\*] after termination of the lease/sublease of such engine. Any such replacement engine shall be of the same make and model as the Lost Engine and shall be leased to SkyWest or XJet, as applicable, on terms substantially the same as the Lost Engine was leased to SkyWest or XJet (subject to the extension of the basic term as contemplated in the last sentence of Section 5(G) above); provided, however, such lease shall be subject and subordinate to the terms of any mortgage or head lease to which such engine is subject. Upon the replacement of a CRJ-700 Additional Aircraft Engine or a CRJ-900 Tranche 1 Additional Aircraft Engine as contemplated in this Section 5(N) with a replacement engine, such replacement engine shall be deemed a CRJ-700 Additional Aircraft Engine or a CRJ-900 Tranche 1 Additional Aircraft Engine, as the case may be, hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;O. <u>Replacement Airframe/Aircraft.</u> If any airframe associated with a Dual-Class Additional Aircraft or if any Dual Class Additional Aircraft is either (i) the subject of an "event of loss" (under and as such term is defined in the lease for such Dual Class Additional Aircraft between Delta (or an affiliate of Delta) and SkyWest or XJet, as applicable) and which is fully insured at the time of such loss as required by the lease for such Dual Class Additional Aircraft between Delta (or an affiliate of Delta) and SkyWest or XJet, as applicable, or (ii) subject to a lease or sublease described in Section 5(G) or 5(H) above which is terminated due to any action or inaction of Delta or any affiliate of Delta, in each case in its capacity as lessor, and which is not attributable to an event of loss of such Dual Class Additional Aircraft or any action or inaction of SkyWest or XJet, as applicable, in each case in its capacity as lessee, then, SkyWest or XJet, as applicable, shall have the right to lease or otherwise acquire a replacement for such Dual Class Additional Aircraft on commercially reasonable terms subject to Delta's prior written consent (and which terms shall be no less favorable to Delta than the

------

**Execution Copy**

terms on which Delta leased or financed the Dual Class Additional Aircraft being replaced) not to be unreasonably withheld (such aircraft/airframe, a "Substitute Aircraft"); provided, that in the case of an event of loss, Delta shall have first received the full amount of the required insurance proceeds stipulated in the lease for such Dual Class Additional Aircraft following an event of loss. Upon SkyWest or XJet's acquisition of such Substitute Aircraft, such aircraft shall be added as a Dual-Class Additional Aircraft under the Agreement for the remainder of the Dual-Class Additional Aircraft Term of the aircraft/airframe so replaced, and subject to the terms and conditions of the Agreement, as amended by this Amendment, each effective upon the initial in-service date within the Delta Connection Program of such Substitute Aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;P. <u>Substitute Engine.</u> This Section 5(P) shall only apply with respect to the CRJ-700 Additional Aircraft and the CRJ-900 Tranche 1 Additional Aircraft and only so long as a CRJ-700 Additional Aircraft Engine or a CRJ-900 Tranche 1 Additional Aircraft Engine is leased under a separate, stand alone engine lease agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) For purposes of applying the provisions of this Section 4.H, the Final Monthly Schedule shall exclude the "E175 Aircraft" and the "Final Monthly E175 Schedule" (in each case, as such terms are defined in that certain Amendment Number Fifteen dated effective as of October 19, 2015 ("Amendment Number Fifteen")).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**I.** Upon no less than [\*\*\*] prior written notice from Operator to Delta, Operator may assign to ExpressJet, and ExpressJet will assume from Operator, all of Operator's rights and obligations (but not less than all) to operate up to [\*\*\*] of the [\*\*\*] CRJ- 700 Aircraft pursuant to the terms of the ExpressJet Agreement as modified by the terms of this Amendment, provided, that ExpressJet is an affiliate of Operator at the time of such assignment. Upon any such assignment, the [\*\*\*] CRJ-700 Aircraft will cease to be Aircraft hereunder and will be considered "Aircraft" and "Assigned [\*\*\*] CRJ-700 Aircraft" under the ExpressJet Agreement (as such terms are defined in the EV Amendment Number Thirteen). In the event of any conflict between the terms and conditions of this Amendment and the ExpressJet Agreement, the terms and conditions of this Amendment shall prevail.

**AMENDED AND RESTATED DELTA CONNECTION AGREEMENT**

This Amendment Number Fifteen (this "Amendment"), dated effective as of October 19, 2015 ("Amendment Number Fifteen Effective Date"), to the Amended and Restated Delta Connection Agreement dated and effective September 8, 2005 (as amended from time to time, the "Agreement"), is between Delta Air Lines, Inc., 1030 Delta Boulevard, Atlanta, Georgia 30320 ("Delta"), and SkyWest Airlines, Inc. ("SkyWest" or "Operator"), 444 South River Road, St. George, Utah 84790. Delta and SkyWest collectively, the "Parties".

WHEREAS, Delta and SkyWest are parties to the Agreement; and

WHEREAS, the Parties desire to amend certain provisions of the Agreement to reflect the agreement as related to certain aircraft manufactured by Embraer, S.A. ("Embraer"); and

NOW, THEREFORE, for and in consideration of the mutual undertakings set forth herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Delta and SkyWest, intending to be legally bound, hereby agree to amend the Agreement as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.** **Defined Terms .** All capitalized terms used but not defined herein shall have the meaning ascribed to such terms in the Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.** **Addition of [\*\*\*] Embraer E-175 Aircraft .** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**A.** Pursuant to Section 1.A.(iii) of the Agreement, the [\*\*\*] Embraer E-175 regional jet aircraft set forth in <u>Exhibit A</u> attached hereto (the "E175 Aircraft") shall be added as Aircraft under, and subject to the terms and conditions of, the Agreement, as amended by this Amendment. Except as provided in <u>Section 3</u> of this Amendment, Operator shall make each E175 Aircraft available to be placed into service within the Delta Connection Program no later than each respective Scheduled In-Service Date as set forth in <u>Exhibit A</u> attached hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**B.** Notwithstanding anything in the Agreement to the contrary, the term for which each E175 Aircraft shall be included as an Aircraft under the Agreement, and subject to the terms and conditions thereof, shall commence on each respective actual in-service date of operating Delta Connection Flights (the "Actual In-Service Date") and terminate upon the earlier of [\*\*\*] (each such period, and any extension or renewal terms, an "E175 Aircraft Term"). The parties acknowledge and agree that nothing in this Amendment shall affect, amend or modify the term of the Agreement, or any termination rights, with respect to any Aircraft that is not an E175 Aircraft and the terms with respect to such other Aircraft shall remain as set forth in the Agreement as of the Amendment Number Fifteen Effective Date. Except as set forth in Section 2.C. below, Delta shall have no obligation to pay or reimburse Operator any Direct Costs, Pass-Through Costs, or any other costs, associated with each E175 Aircraft prior to the Actual In-Service Date of such E175 Aircraft.

Notwithstanding the provisions of Article 11.A of the Agreement, Delta's extension rights with respect to the term of each E175 Aircraft shall be limited to up to [\*\*\*] terms subject to the terms and conditions set forth in this Clause 2.B. Any such extension will require (i) [\*\*\*] prior written notice from Delta to Operator prior to the expiration of the initial term or the subsequent extension term, as the case may be, of the applicable E175 Aircraft and (ii) the execution and delivery of a mutually agreed upon extension agreement as to the applicable

------

**EXECUTION VERSION**

E175 Aircraft at least [\*\*\*] prior to the expiration of such initial term or the subsequent extension term, as the case may be, including as to the Direct Costs to be applied during the applicable extension term, each party to negotiate in good faith with respect to such extension agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**C.** (i) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) <u>E175 Aircraft Configuration</u>. Except as set forth in this Section 2.C.(ii), Operator shall cause Embraer to deliver each of the E175 Aircraft in the configuration specified by Delta to Operator as of the Amendment Number Fifteen Effective Date. Delta and Operator acknowledge and agree that Delta may elect to add WiFi, on-board ovens, and/or polycarbonate class dividers (each, an "Add-On Item") to the E175 Aircraft, and if Delta makes any such election Operator shall procure each such Add-On Item from a third party vendor selected by Delta in its sole discretion [\*\*\*]. Unless Delta notifies Operator that Delta has selected a third party vendor to install any of the Add-On Items on the E175 Aircraft, Operator shall install (or, as to the WiFi only, cause a third party vendor to install) the Add-On Items on the E175 Aircraft prior to each such aircraft's respective Actual In- Service Date [\*\*\*]. As to the WiFi, installation requires [\*\*\*]. Accordingly, the references to [\*\*\*] in <u>Exhibit A</u> hereto shall be increased to [\*\*\*] if Delta elects to add the WiFi to the E175 Aircraft. Any delay caused by Delta or any such third party vendor selected by Delta with respect to the procurement or installation of any Add-On Item shall (i) be deemed due to an event that was substantially within the control of, or caused by, some action or inaction of Delta for purposes of Section 2.C.(i), and (ii) be deemed principally attributable to an action of Delta for purposes of Section 3.B of this Amendment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**D.** (i) The Base Rate Costs to be applied to the E175 Aircraft for the entirety of their respective [\*\*\*] initial terms [\*\*\*] shall be as set forth in <u>Exhibit B</u> attached hereto. [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Delta shall have no obligation to pay SkyWest the Block Hour Payment contemplated in Section 3.D of the Agreement with respect to the E175 Aircraft. For the avoidance of doubt, amounts related to the Block Hour Payment that Delta pays for other Aircraft (that are not the E175 Aircraft) under the Agreement are already included as part of the Base Rate Costs for the E175 Aircraft set forth in <u>Exhibit B</u> attached hereto. In addition, Delta shall pay Operator, or Operator shall pay Delta, as applicable, amounts related to the Performance Incentives and Penalties in accordance with, and subject to, the terms and conditions set forth in <u>Exhibit E</u> attached hereto. Operator and Delta each acknowledge and agree that (y) the performance levels provided for in <u>Exhibit E</u> shall be applicable only for the purposes of determining the corresponding incentive payments and/or penalties provided for in <u>Exhibit E</u> and may not be used for purposes of Section 11(E)(1)(v) of the Agreement and (z) Operator's unadjusted completion rate of the Delta Connection Flights scheduled to be operated by Operator with the E175 Aircraft will be included in Operator's completion rate under the Agreement for purposes of Section 11(E)(1)(v) of the Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) With respect to each E175 Aircraft engine serial number (ESN) set forth on <u>Exhibit A</u> attached hereto (the "Delivery Date E175 Engines") and the [\*\*\*] engines identified in Exhibit F attached hereto (the "Spare E175 Engines", and collectively with the Delivery Date E175 Engines, the "E175 Engines"), "Engine Maintenance Expense" as defined in Section 3.A.(ii)(1) of the Agreement for the E175 Engines shall be as provided in <u>Exhibit C</u> attached hereto; provided, in all events, such costs shall not be treated as a Pass Through Cost but shall be deemed a Base Rate Cost for purposes of the Agreement. [\*\*\*] The E175 Engines shall be used only for the operation of any E175 Aircraft in connection with the Delta Connection

------

**EXECUTION VERSION**

Program. Operator shall at all times during the respective E175 Aircraft Term maintain a sufficient number of Spare E175 Engines to operate, as contemplated by this Amendment, all of the E175 Aircraft under the scope of the Agreement at such time. In the event Operator needs additional spare engines in order to maintain a sufficient number of spare engines for the E175 Aircraft, upon written notice to Delta, Operator may include additional spare engines as Spare E175 Engines under the terms of the Agreement and Exhibit F shall be revised accordingly.

Subject to Delta's prior written consent, such consent not to be unreasonably withheld or delayed, Operator may remove and, if necessary, replace an E175 Engine as a result of damage or destruction of such engine. In such event <u>Exhibit A</u> or <u>Exhibit F</u> hereto shall be amended to reflect such removal and replacement, if applicable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Notwithstanding the definition of Aircraft Rent/Ownership Costs as set forth in Section 3.A.(ii)(2) of the Agreement, with respect to each E175 Aircraft, Aircraft Rent/Ownership Costs shall be as set forth in <u>Exhibit D</u> attached hereto. Operator's actual Aircraft Rent/Ownership Cost with respect to each E175 Aircraft will be [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) As to the E175 Aircraft only, the first sentence in the fifth paragraph of Section 3.E shall be amended and restated as follows:

"Notwithstanding anything herein to the contrary, if SKYW is unable to operate any of the E175 Aircraft, or any of the Delta Connection Flights scheduled to be operated by any of the E175 Aircraft, due to a strike, labor dispute or work stoppage; <u>provided</u>, in each such case that such event is substantially within the control of, or caused by, some action or inaction of SKYW or an affiliate of SKYW, Delta shall not be obligated to pay SKYW any Direct Costs or any other amounts in connection with such non-operated E175 Aircraft and Delta Connection Flights."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ix) Notwithstanding the provisions of Article 1.D. of the Agreement, the Delta Connection Flights to be operated by the E175 Aircraft shall be primarily supported by crew and maintenance bases of Operator located at airports in the [\*\*\*]. As of the Amendment Number Fifteen Effective Date, such crew and maintenance bases are as follows: crew bases [\*\*\*], line maintenance bases [\*\*\*] and overnight maintenance bases [\*\*\*]. If to a material degree, the E175 Aircraft are scheduled such that the crew and maintenance bases with respect to the E175 Aircraft are not located in such airports, such act or omission shall not be a breach of the Agreement; provided, however, in any such event Delta and Operator will negotiate in good faith to agree on an appropriate economic adjustment (up or down) to the Direct Costs solely to account for the actual bases and/or maintenance bases used to support the Delta Connection Flights to be operated by the E175 Aircraft.

If the number of Aircraft (excluding any E175 Aircraft) operated by Operator pursuant to the terms of the Agreement as of [\*\*\*], is substantially the same or greater than the number of Aircraft (excluding any E175 Aircraft) operated by Operator pursuant to the terms of the Agreement as of the Amendment Number Fifteen Effective Date (excluding the E175

------

**EXECUTION VERSION**

Aircraft) and if Delta informs Operator that such number of Aircraft (excluding the E175 Aircraft) will not materially decrease for a period of [\*\*\*], then, upon written notice from Delta to Operator provided on or before [\*\*\*], Operator shall install and maintain an additional overnight maintenance base at an airport selected by Operator and approved in advance by Delta (such approval not to be unreasonably withheld or delayed) that is capable of performing typical overnight maintenance functions on a sufficient number of E175 Aircraft to adequately support the entire E175 Aircraft fleet. Such overnight maintenance base shall be completed [\*\*\*] on or before [\*\*\*]. Notwithstanding the foregoing, if Delta in good faith believes Operator can adequately support the entire E175 Aircraft fleet with Operator's then-existing maintenance bases located in the [\*\*\*] and Delta notifies Operator of such belief by no later than [\*\*\*] then Operator shall have no obligation to complete the additional overnight maintenance base contemplated in the first sentence of this paragraph.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**E.** Notwithstanding the provisions of Article 1.D., if (i) Delta submits a proposed monthly schedule of Delta Connection Flights to be operated by the E175 Aircraft during such month (each, a "Proposed Monthly E175 Schedule") which provides for average daily scheduled utilization measured on a calendar month basis in the aggregate for the E175 Aircraft fleet (taking into account scheduled maintenance) available to schedule ("Average E175 Utilization") greater than an average of [\*\*\*] per E175 Aircraft [\*\*\*] during the applicable month of determination (the "Maximum E175 Utilization Level") and (ii) Operator, after conducting a good faith review and analysis of such Proposed Monthly E175 Schedule and its crew availability for such month, determines, in good faith, that it is unable to operate the Proposed Monthly E175 Schedule as provided by Delta, then, within [\*\*\*] following receipt of such Proposed Monthly E175 Schedule, Operator shall have the option, upon delivering to Delta written notice, to request a reduction in such scheduled block hours in order to reduce the Average E175 Utilization to the applicable Maximum Utilization Level or a greater utilization level as specified by Operator (an "E175 Schedule Reduction Request"). If Operator does not respond within such [\*\*\*] period, any such non-response shall be deemed a waiver by Operator of its right to request any schedule reduction with respect to such month's Proposed Monthly E175 Schedule. Upon receipt of an E175 Schedule Reduction Request, Delta shall amend the Proposed Monthly E175 Schedule initially delivered by Delta to Operator to reduce the Average Utilization reflected in such Proposed Schedule to a level no greater than the Maximum Utilization Level or greater level as specified by Operator and such reduction shall thereafter be reflected in the applicable final monthly schedule for the E175 Aircraft (a "Schedule Reduction"). Flights cancelled due to any such Schedule Reduction shall not be taken into account for any purposes under this Agreement, including, as pertaining to performance goals or other penalties provided for <u>Exhibit E</u> attached hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**F.** [\*\*\*]. Operator shall provide Delta with a written statement of the actual foregoing costs for each E175 Aircraft, together with accompanying support showing reasonable details of such costs. [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**G.** Operator shall select the vendor(s) to perform and complete all maintenance work associated with the E175 Aircraft (including all engines and parts) in Operator's sole and absolute discretion; provided, however, if Delta requests Operator to change a vendor performing engine maintenance work with respect to the E175 Engines and if [\*\*\*] then, Operator will cooperate with Delta with respect to such requested change in vendor for the E175 Engine maintenance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**H.** Other than the last two sentences therein, the provisions of Article 3.G. of the Agreement shall not apply with respect to the operations of the E175 Aircraft.

"<u>Delivery Date</u>" means, as to each E175 Aircraft, the date such aircraft is delivered to Operator by Embraer.

"<u>EMB Excusable Delay</u>" means a delay in the delivery of an E175 Aircraft attributable to (i) a force majeure event affecting Embraer (including, but not limited to, acts of God, war or state of war, civil war, insurrection, fire, terrorist incident, accident, explosion, flood, act of government, requisition or strike) or (ii) an inability despite commercially reasonable efforts by Embraer for Embraer to procure or export any materials, equipment, accessories, parts or means of transport necessary for the production of the applicable E175 Aircraft.

"<u>EMB Non-Excusable Delay</u>" [\*\*\*]

"<u>Excusable Delay Penalty Period</u>" [\*\*\*]

"<u>Non-Excusable Delay Penalty Period</u>" [\*\*\*]

"<u>Operator Caused Delay</u>" [\*\*\*]

"<u>Operator Caused Delay Penalty Period</u>" [\*\*\*]

"<u>Scheduled Delivery Date</u>" means, as to each E175 Aircraft, the last day of the Scheduled Delivery Month of such aircraft as set forth on <u>Exhibit A</u> hereto.

"<u>Service Delay Penalty Period</u>" [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**B.** <u>Delays in Actual In-Service Date</u>. Operator hereby agrees to use commercially reasonable best efforts to cause each of the E175 Aircraftto be available to be placed into service within the Delta Connection Program no later than the respective Scheduled In-Service Date (as set forth in Exhibit A hereto). If following the Delivery Date of the respective E175 Aircraft, such aircraft is not placed in service within the Delta Connection Program by such E175 Aircraft's Scheduled In-Service Date (such E175 Aircraft, a " <u>Delayed In-Service Aircraft</u> "), then, during each day of the Service Delay Penalty Period, Operator shall pay Delta an amount of [\*\*\*] during the Service Delay Penalty Period; <u>provided</u>, (i) Operator is obligated at such time to pay the full Aircraft Rent/Ownership Costs (disregarding differences in timing as to any such payments under the respective financing documents) with respect to the Delayed In-Service Aircraft, and if not, the amount shall be increased from [\*\*\*] to[\*\*\*] and (ii) Operator shall have no obligation to make such payment for any delay principally attributable to any action or omission of Delta. Delta agrees to promptly place into service within the Delta Connection Program in accordance with Delta's regular scheduling procedures such Delayed In-Service Aircraft following receipt of written certification from Operator that the aircraft is readily available and fit for service within the Delta Connection Program as contemplated by this Amendment. In addition to the foregoing, if the Delayed In- Service Aircraft is not available for service within the Delta Connection Program as

------

**EXECUTION VERSION**

contemplated by this Amendment on or before the [\*\*\*] following its Scheduled Delivery Date, then, after such [\*\*\*] and continuing until Delta receives written certification described above from Operator that the aircraft is readily available to be placed into service within the Delta Connection Program as contemplated by this Amendment, Delta shall have the right, but not the obligation, to remove such Delayed In-Service Aircraft from the scope of the Agreement upon written notice to Operator. As to matters arising with respect to the delay in such Delayed In-Service Aircraft being available for scheduled service, the foregoing represents Delta's sole and exclusive remedies attributable to such matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**C.** <u>Delay in Delivery Caused by an EMB Excusable Delay.</u> Operator hereby agrees to use commercially reasonable efforts to cause Embraer to deliver each E175 Aircraft by no later than such E175 Aircraft's Scheduled Delivery Date. If an E175 Aircraft is not delivered to Operator on or before its Scheduled Delivery Date and if such delay in delivery is attributable to an EMB Excusable Delay (such E175 Aircraft, an " <u>Excusable Delayed Aircraft</u> "), then Operator shall pay Delta an amount of [\*\*\*] during the Excusable Delay Penalty Period. Unless otherwise removed from the Agreement as provided below in this Section 3.C, the parties shall promptly determine the revised Scheduled In-Service Date following the delivery to Operator of the Excusable Delayed Aircraft. In addition to the foregoing, if the Excusable Delayed Aircraft is not delivered to Operator by Embraer on or before the [\*\*\*] following such E175 Aircraft's Scheduled Delivery Date as a result of an EMB Excusable Delay, then either party, upon written notice to the other party delivered within [\*\*\*] following such [\*\*\*], may terminate from the scope of the Agreement such Excusable Delayed Aircraft. If either party fails to give such notice within such [\*\*\*] period, such party shall be deemed to have waived its right of termination set forth in the preceding sentence. As to matters arising with respect to the delay in the delivery of such Excusable Delayed Aircraft, the foregoing represents, as the each party, such party's sole and exclusive remedy attributable to such matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**D.** <u>Delay in Delivery Caused by an EMB Non-Excusable Delay.</u> Operator hereby agrees to use commercially reasonable efforts to cause Embraer to deliver each E175 Aircraft by no later than such E175 Aircraft's Scheduled Delivery Date. If an E175 Aircraft is not delivered to Operator on or before its Scheduled Delivery Date and if such delay in delivery is attributable to an EMB Non-Excusable Delay (such E175 Aircraft, an " <u>Non-Excusable Delayed Aircraft</u> "), then Operator shall pay Delta an amount of [\*\*\*] during the Non-Excusable Delay Penalty Period; <u>provided</u>, Operator shall have no obligation to make such payment for any delay principally attributable to any action or omission of Delta. Unless otherwise removed from the Agreement as provided below in this Section 3.D, the parties shall promptly determine the revised Scheduled In-Service Date following the delivery to Operator of the Non-Excusable Delayed Aircraft. In addition to the foregoing, if the Non-Excusable Delayed Aircraft is not delivered to Operator by Embraer on or before the [\*\*\*] following such E175 Aircraft's Scheduled Delivery Date as a result of an EMB Non-Excusable Delay, then either party, upon written notice to the other delivered within [\*\*\*] following such [\*\*\*], may terminate from the scope of the Agreement such Non-Excusable Delayed Aircraft. If either party fails to give such notice within such [\*\*\*], such party shall be deemed to have waived its right of termination set forth in the preceding sentence. As to matters arising with respect to the delay in the delivery of such Non-Excusable Delayed Aircraft, the foregoing represents, as to each party, such party's sole and exclusive remedy attributable to such matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**E.** <u>Delay in Delivery Caused by an Operator Caused Delay</u>. Operator hereby agrees to use commercially reasonable efforts to cause Embraer to deliver each E175 Aircraft by no later

**EXECUTION VERSION**

than such E175 Aircraft's Scheduled Delivery Date. If an E175 Aircraft is not delivered to Operator on or before its Scheduled Delivery Date and if such delay in delivery is attributable to an Operator Caused Delay (such E175 Aircraft, an "<u>Operator Delayed Aircraft</u>"), then Operator shall pay Delta an amount of [\*\*\*] during the Operator Caused Delay Penalty Period. Unless otherwise removed from the Agreement as provided below in this Section 3.E, the parties shall promptly determine the revised Scheduled In-Service Date following the delivery to Operator of the Operator Delayed Aircraft. In addition to the foregoing, if the Operator Delayed Aircraft is not delivered to Operator by Embraer on or before the [\*\*\*] following such E175 Aircraft's Scheduled Delivery Date as a result of an Operator Caused Delay, then Delta shall have the right, but not the obligation, to remove such Operator Delayed Aircraft from the scope of the Agreement upon written notice to Operator. As to matters arising with respect to the delay in the delivery of such Operator Delayed Aircraft, the foregoing represents Delta's sole and exclusive remedy attributable to such matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**F.** With respect to any amounts owed to Delta pursuant to this Section 3, Delta shall be entitled to offset or recoup the full amount of any such payments from any subsequent Provisioning Payment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.** **Removal of E175 Aircraft**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**A.** In connection with the preparation and delivery of the final monthly schedule for the E175 Aircraft (each such monthly schedule, the "Final Monthly E175 Schedule"), if after delivery of such schedule by Delta to Operator, Operator informs Delta in writing that Operator cannot fully operate the Final Monthly E175 Schedule for such month for any reason that is substantially within the control of Operator (including, without limitation, crew availability) and Operator requests the removal or cancellation of scheduled flights (such requested removals and cancellations, "Operator Controlled Cancellations") or if Delta, after consultation with Operator, in good faith believes Operator cannot fully operate the Final Monthly E175 Schedule for such month and Delta removes or cancels scheduled flights as result thereof (such removals and cancellations, "Delta Cancellations"), then, Delta shall have the right to remove from the terms of the Agreement (as modified by this Amendment) for the applicable month(s) at issue (or, at Delta's sole election, on a permanent basis), [\*\*\*] (any such E175 Aircraft so removed, a "Removed E175 Aircraft"). Delta shall provide written notice of such removal (temporary or permanent) within [\*\*\*] after receipt of the written notice of Operator Controlled Cancellations with respect to Operator Controlled Cancellations or, with respect to Delta Cancellations, within [\*\*\*] after delivery of the Final Monthly Schedule, whichever is applicable. With respect to any E175 Removed Aircraft, Delta will [\*\*\*]. In determining the number of E175 Aircraft that may be removed, fractions will be rounded up or down to the nearest whole number, with a number [\*\*\*] being rounded down to the nearest whole number. For the avoidance of doubt, (i) with respect to Operator Controlled Cancellations and Delta Cancellations associated with any E175 Aircraft that is not removed, temporarily or permanently, from the terms of the Agreement pursuant to this Section 4.A, all such cancellations shall be considered non-completed flights for purposes of the calculation of any incentives and penalties as provided in <u>Exhibit E</u> and (ii) Schedule Reduction Requests shall not be deemed Operator Controlled Cancellations or Delta Cancellations.

In preparing the Final Monthly E175 Schedule, such schedule shall take into account scheduled maintenance for the E175 Aircraft and, if applicable, the repair time for damaged E175 Aircraft and accordingly, such aircraft shall not be available for scheduling during the maintenance or repair period, as applicable. For avoidance of doubt, the terms of this

**EXECUTION VERSION**

Section 4 shall not permit the removal (temporary or permanent) of any E175 Aircraft from the terms of this Agreement as a result of scheduled maintenance and repair time; provided, however, notwithstanding the foregoing, if Operator is unable to operate any of the E175 Aircraft, or any of the Delta Connection Flights, due to an E175 Aircraft being damaged and such damage was due to an event that was substantially within the control of, or caused by, some action or inaction of Operator, Delta shall not be obligated to pay Operator any Direct Costs, or any other amounts, in connection with such non-operated E175 Aircraft and Delta Connection Flights during the period that Operator is unable to operate such damaged E175 Aircraft or the Delta Connection Flights

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**B.** If [\*\*\*] or more E175 Aircraft are removed on a temporary basis from the Agreement for [\*\*\*] over any [\*\*\*] rolling period, then either Delta or Operator shall, upon [\*\*\*] prior written notice to the other party, have the right to remove on a permanent basis from the terms of the Agreement the number of E175 Aircraft that have been so removed for such [\*\*\*] period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**C.** If [\*\*\*] or more E175 Aircraft are permanently removed from the terms of this Agreement as provided in this Section 4, then, Delta may, upon [\*\*\*] prior written notice to Operator, have the right to remove all, but not less than all, remaining E175 Aircraft from the terms of the Agreement. If [\*\*\*] or more E175 Aircraft are permanently removed from the terms of this Agreement as provided in this Section 4, then, Operator may, upon [\*\*\*] prior written notice to Delta, have the right to remove all, but not less than all, remaining E175 Aircraft from the terms of the Agreement. If either party exercises its right to remove the remaining E175 Aircraft from the terms of the Agreement as provided in this Section 4.C, the parties shall determine a mutually agreed upon wind-down schedule with respect to the remaining E175 Aircraft, provided in no event shall such wind-down schedule be longer than [\*\*\*] after delivery of the election notice required by this Section 4.C.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**D.** If [\*\*\*] or more E175 Aircraft are, in each case, not available to be placed into service with the Delta Connection Program as contemplated by this Amendment more than [\*\*\*] after their respective Scheduled-In Service Dates and each such delay is due to an event that was substantially within the control of, or caused by, some action or inaction of Operator or an affiliate of Operator (including, as a result of a crew shortage), then, such unavailability shall be a material breach of the Agreement by Operator and Delta may exercise any and all of its rights and remedies to which it may be entitled with respect to such material breach in accordance with the Agreement. In addition to such rights and remedies, Delta shall also have the right, but not the obligation, upon written notice to Operator to remove all E175 Aircraft from the terms of the Agreement. In such event, the parties shall determine a mutually agreed upon wind-down schedule with respect to the E175 Aircraft then subject to the Agreement, provided in no event shall such wind-down schedule be longer than [\*\*\*] after delivery of the foregoing election notice. The foregoing termination right must be exercised within [\*\*\*] following the end of the [\*\*\*] late period of the [\*\*\*] delayed E175 Aircraft. Failure by Delta to exercise such right within such [\*\*\*] period shall be deemed a waiver by Delta of its right of termination set forth in this Section 4.D.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**E**. [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**F.** With respect to any E175 Aircraft that are temporarily removed from the Agreement pursuant to Section 4.A above, Operator shall not (i) operate or use any such E175 Aircraft for itself or on behalf of any third party or (ii) lease, sublease, transfer, sell, assign or otherwise convey any interest into any such E175 Aircraft to any third party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)For the period beginning [\*\*\*] through and including [\*\*\*], Operator's respective Base Rate Costs for certain of the CRJ-200, CRJ-700, and CRJ-900 Aircraft operated by Operator under the Agreement shall be as set forth on <u>Exhibit A</u> attached hereto and incorporated herein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)In consideration of the establishment of the Base Rate Costs through calendar year [\*\*\*] as set forth in this Section 2.A(i) of this Amendment, Delta hereby waives [\*\*\*] for the period beginning on [\*\*\*] and ending on [\*\*\*] (the "Waiver Period").

If Delta elects to remove an aircraft from service as provided above, then (i) Delta shall provide written notice to SI within [\*\*\*] of such removal and shall identify whether such aircraft is an EV CRJ-700 or a [\*\*\*] CRJ-700 Aircraft and (ii) Operator covenants and agrees that it shall not operate any Delta Connection Flights with any E170+ Aircraft prior to the removal of a corresponding EV CRJ-700 or a [\*\*\*] CRJ-700 Aircraft, the FAA registration number of each such removed EV CRJ-700 or [\*\*\*] CRJ-700 Aircraft to be mutually agreed between Delta and SI. Upon the removal of such EV CRJ-700 from the ASA Delta Connection Agreement or such [\*\*\*] CRJ-700 Aircraft from the Agreement, Delta shall have no further payment obligations with respect to such removed aircraft with respect to any periods following such removal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. (i) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) <u>E170+ Aircraft Configuration</u>. Except as set forth in this Section 2.D.(ii), Operator shall cause Embraer to deliver each of the E170+ Aircraft in the configuration specified in <u>Exhibit G</u> attached hereto and incorporated herein. Delta and Operator acknowledge and agree that Delta may elect to add WiFi, on-board ovens, polycarbonate class dividers, Delta-branded placarding, and/or Delta-branded passenger service unit lenses (each, an "Add-On Item") to the E170+ Aircraft, and if Delta makes any such election Operator shall procure each such Add-On Item from a third party vendor selected by Delta in its sole discretion [\*\*\*]. Unless Delta notifies Operator that Delta has selected a third party vendor to install any of the Add- On Items on the E170+ Aircraft, Operator shall install (or, as to the WiFi only, cause a third party vendor to install) the Add-On Items on the E170+ Aircraft prior to each such aircraft's respective Actual In-Service Date [\*\*\*]. As to the WiFi, installation requires [\*\*\*]. Accordingly, the references to [\*\*\*] in <u>Exhibit A</u> hereto and in Section 2(D)(i) above shall, in each case, be increased to [\*\*\*] if Delta elects to add the WiFi to the E170+ Aircraft. Any delay caused by Delta or any such third party vendor selected by Delta with respect to the procurement or installation of any Add-On Item shall (i) be deemed due to an event that was

substantially within the control of, or caused by, some action or inaction of Delta for purposes of Section 2.D.(i), and (ii) be deemed principally attributable to an action of Delta for purposes of Section 3.B of this Amendment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. (i) The Base Rate Costs to be applied to the E170+ Aircraft for the entirety of their respective [\*\*\*] initial terms, [\*\*\*] shall be as set forth in <u>Exhibit B</u> attached hereto. [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)Delta shall have no obligation to pay Operator the Block Hour Payment contemplated in Section 3.D of the Agreement with respect to the E170+ Aircraft. For the avoidance of doubt, amounts related to the Block Hour Payment that Delta pays for other Aircraft (that are not the E170+ Aircraft) under the Agreement are already included as part of the Base Rate Costs for the E170+ Aircraft set forth in <u>Exhibit B</u> attached hereto. In addition, Delta shall pay Operator, or Operator shall pay Delta, as applicable, amounts related to the Performance Incentives and Penalties in accordance with, and subject to, the terms and conditions set forth in <u>Exhibit E</u> attached hereto. Operator and Delta each acknowledge and agree that (y) the performance levels provided for in <u>Exhibit E</u> shall be applicable only for the purposes of determining the corresponding incentive payments and/or penalties provided for in <u>Exhibit E</u> and may not be used for purposes of Section 11(E)(1)(v) of the Agreement and (z) Operator's unadjusted completion rate of the Delta Connection Flights scheduled to be operated by Operator with the E170+ Aircraft will be included in Operator's completion rate under the Agreement for purposes of Section 11(E)(1)(v) of the Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)With respect to each E170+ Aircraft engine serial number (ESN) set forth on <u>Exhibit A</u> attached hereto (the "Delivery Date E170+ Engines") and [\*\*\*] engines identified in <u>Exhibit F</u> attached hereto (each, a "Spare E170+ Engine", and collectively with the Delivery Date E170+ Engines, the "E170+ Engines"), "Engine Maintenance Expense" as defined in Section 3.A.(ii)(1) of the Agreement for the E170+ Engines shall be as provided in <u>Exhibit C</u> attached hereto; provided, in all events, such costs shall not be treated as a Pass Through Cost but shall be deemed a Base Rate Cost for purposes of the Agreement. [\*\*\*]

The E175 Engines (as defined in Amendment Number Fifteen to the Agreement dated as of October 19, 2015 ("Amendment Number Fifteen") and the E170+ Engines shall be used only for the operation of any E175 Aircraft (as defined in Amendment Number Fifteen) and any E170+ Aircraft in connection with the Delta Connection Program. Operator shall at all times during the respective E170+ Aircraft Term and the E175 Aircraft Term (as defined in Amendment Number Fifteen) maintain a sufficient number of Spare E175 Engines and Spare E170+ Engines to operate, as contemplated by this Amendment, all of the E175 Aircraft and E170+ Aircraft under the scope of the Agreement at such time. In the event Operator needs additional spare engines in order to maintain a sufficient number of spare engines for the E175 Aircraft and the E170+ Aircraft, upon written notice to Delta, Operator may include additional spare engines as Spare E175 Engines or Spare E170+ Engines, as applicable, under the terms of the Agreement and <u>Exhibit F</u> shall be revised accordingly (and, as necessary, Exhibit F of Amendment Number Fifteen).

Subject to Delta's prior written consent, such consent not to be unreasonably withheld or delayed, Operator may remove and, if necessary, replace an E170+ Engine as a result of damage or destruction of such engine. In such event <u>Exhibit A</u> or <u>Exhibit F</u> hereto shall be amended to reflect such removal and replacement, if applicable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv)Notwithstanding the definition of Aircraft Rent/Ownership Costs as set forth in Section 3.A.(ii)(2) of the Agreement, with respect to each E170+ Aircraft, Aircraft Rent/Ownership

**EXECUTION COPY**

Costs shall be as set forth in <u>Exhibit D</u> attached hereto. Operator's actual Aircraft Rent/Ownership Cost with respect to each E170+ Aircraft will be [\*\*\*].

[\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi)As to the E170+ Aircraft only, the first sentence in the fifth paragraph of Section 3.E. of the Agreement shall be amended and restated as follows:

"Notwithstanding anything herein to the contrary, if SKYW is unable to operate any of the E170+ Aircraft, or any of the Delta Connection Flights scheduled to be operated by any of the E170+ Aircraft, due to a strike, labor dispute or work stoppage; <u>provided</u>, in each such case that such event is substantially within the control of, or caused by, some action or inaction of SKYW or an affiliate of SKYW, Delta shall not be obligated to pay SKYW any Direct Costs or any other amounts in connection with such non-operated E170+ Aircraft and Delta Connection Flights."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ix)Notwithstanding the provisions of Article 1.D. of the Agreement, the Delta Connection Flights to be operated by the E170+ Aircraft shall be primarily supported by crew and maintenance bases of Operator located at airports in [\*\*\*]. As of the Amendment Number Twenty-Two Effective Date, such crew and maintenance bases are as follows: crew bases ([\*\*\*]), line maintenance bases ([\*\*\*]) and overnight maintenance bases ([\*\*\*]). If to a material degree, the E170+ Aircraft are scheduled such that the crew and maintenance bases with respect to the E170+ Aircraft are not located in such airports, such act or omission shall not be a breach of the Agreement; provided, however, in any such event Delta and Operator will negotiate in good faith to agree on an appropriate economic adjustment (up or down) to the Direct Costs solely to account for the actual bases and/or maintenance bases used to support the Delta Connection Flights to be operated by the E170+ Aircraft.

**EXECUTION COPY**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. Notwithstanding the provisions of Article 1.D. of the Agreement, if (i) Delta submits a proposed monthly schedule of Delta Connection Flights to be operated by the E170+ Aircraft during such month (each, a "Proposed Monthly E170+ Schedule") which provides for average daily scheduled utilization measured on a calendar month basis in the aggregate for the E170+ Aircraft fleet (taking into account scheduled maintenance) available to schedule ("Average E170+ Utilization") greater than an average of [\*\*\*] per E170+ Aircraft [\*\*\*] during the applicable month of determination (the "Maximum E170+ Utilization Level") and (ii) Operator, after conducting a good faith review and analysis of such Proposed Monthly E170+ Schedule and its crew availability for such month, determines, in good faith, that it is unable to operate the Proposed Monthly E170+ Schedule as provided by Delta, then, within [\*\*\*] following receipt of such Proposed Monthly E170+ Schedule, Operator shall have the option, upon delivering to Delta written notice, to request a reduction in such scheduled block hours in order to reduce the Average E170+ Utilization to the applicable Maximum Utilization Level or a greater utilization level as specified by Operator (an "E170+ Schedule Reduction Request"). If Operator does not respond within such [\*\*\*] period, any such non- response shall be deemed a waiver by Operator of its right to request any schedule reduction with respect to such month's Proposed Monthly E170+ Schedule. Upon receipt of an E170+ Schedule Reduction Request, Delta shall amend the Proposed Monthly E170+ Schedule initially delivered by Delta to Operator to reduce the Average Utilization reflected in such Proposed Schedule to a level no greater than the Maximum Utilization Level or greater level as specified by Operator and such reduction shall thereafter be reflected in the applicable final monthly schedule for the E170+ Aircraft (a "Schedule Reduction"). Flights cancelled due to any such Schedule Reduction shall not be taken into account for any purposes under this Agreement, including, as pertaining to performance goals or other penalties provided for <u>Exhibit E</u> attached hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;G. [\*\*\*]. Operator shall provide Delta with a written statement of the actual foregoing costs for each E170+ Aircraft, together with accompanying support showing reasonable details of such costs. [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;H. Operator shall select the vendor(s) to perform and complete all maintenance work associated with the E170+ Aircraft (including all engines and parts) in Operator's sole and absolute discretion; provided, however, if Delta requests Operator to change a vendor performing engine maintenance work with respect to the E170+ Engines and if [\*\*\*] then, Operator will cooperate with Delta with respect to such requested change in vendor for the E170+ Engine maintenance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I. Other than the last two sentences therein, the provisions of Article 3.G. of the Agreement shall not apply with respect to the operations of the E170+ Aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;J. [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;K. [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;L. Operator acknowledges that if [\*\*\*]-seat aircraft operated by ASA under the ASA Delta Connection Agreement are removed from operations at [\*\*\*] pursuant to the ASA Delta Connection Agreement, then, Delta may, on a one-for-one basis, schedule up to [\*\*\*] -seat Aircraft into and out of [\*\*\*] to be operated by Operator pursuant to this Agreement (each, a "[\*\*\*] Aircraft"); provided, Delta agrees to use commercially reasonable efforts to transition such [\*\*\*] Aircraft out of [\*\*\*] by no later than [\*\*\*]. If Delta is unable to transition such [\*\*\*] Aircraft out of [\*\*\*] by [\*\*\*] then the parties shall meet to discuss Delta's anticipated

------

**EXECUTION COPY**

Aircraft fleet location. Delta agrees that for any period that an Aircraft is operating into and out of [\*\*\*], the applicable "block hour" Base Rate Cost set forth in <u>Exhibit B</u> of the Agreement with respect to Delta Connection Flights operated by Operator pursuant to the Agreement into and out of [\*\*\*] will be increased by [\*\*\*] per block hour. Delta further acknowledges that the crews for such [\*\*\*] Aircraft will be based in [\*\*\*]. If during any rolling [\*\*\*] period beginning after [\*\*\*] (i) Operator's "pilot D0 delay" rate is less than [\*\*\*] or (ii) Operator's "pilot 3+ hour delay" rate is greater than [\*\*\*] scheduled flights per [\*\*\*] scheduled flights ((i) and (ii) together, the "Crew Performance Targets"), then Delta and Operator shall meet and discuss in good faith (i) the implementation of a plan for Operator to meet the Crew Performance Targets, and (ii) whether Operator's performance vis a vis the Crew Performance Targets warrants the addition of a crew domicile in [\*\*\*]. Upon mutual agreement of the parties, Operator shall add a crew domicile in [\*\*\*]. Delta agrees to perform (or cause an affiliate or third party to perform) line maintenance and overnight maintenance required for such [\*\*\*] Aircraft in [\*\*\*], at a labor cost equal to $[\*\*\*] per labor hour, subject to a mutually agreeable maintenance agreement, including scopes of work and billing structure. For the avoidance of doubt, the first [\*\*\*] rolling period for which the foregoing determination will be made is for the [\*\*\*] period from and including [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.** **Delay** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**A.** For purposes of this Section 3, the following terms shall have the respective meaning set forth herein:

"<u>Delivery Date</u>" means, as to each E170+ Aircraft, the date such aircraft is delivered to Operator by Embraer.

"<u>EMB Excusable Delay</u>" [\*\*\*]

"<u>EMB Non-Excusable Delay</u>" [\*\*\*]

"<u>Excusable Delay Penalty Period</u>" [\*\*\*]

"<u>Non-Excusable Delay Penalty Period</u>" [\*\*\*]

"<u>Operator Caused Delay</u>" [\*\*\*]

"<u>Operator Caused Delay Penalty Period</u>" [\*\*\*]

"<u>Scheduled Delivery Date</u>" means, as to each E170+ Aircraft, the last day of the Scheduled Delivery Month of such aircraft as set forth on <u>Exhibit A</u> hereto.

"<u>Service Delay Penalty Period</u>" [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**B.** <u>Delays in Actual In-Service Date</u>. Operator hereby agrees to use commercially reasonable best efforts to cause each of the E170+ Aircraft to be available to be placed into service within the Delta Connection Program no later than the respective Scheduled In-Service Date (as set forth in Exhibit A hereto). If following the Delivery Date of the respective E170+ Aircraft, such aircraft is not placed in service within the Delta Connection Program by such E170+ Aircraft's Scheduled In-Service Date (such E170+ Aircraft, a " <u>Delayed In-Service Aircraft</u> "), then, during each day of the Service Delay Penalty Period, Operator shall pay Delta an amount of [\*\*\*] during the Service Delay Penalty Period; <u>provided</u>, (i) Operator is

------

**EXECUTION COPY**

obligated at such time to pay the full Aircraft Rent/Ownership Costs (disregarding differences in timing as to any such payments under the respective financing documents) with respect to the Delayed In-Service Aircraft, and if not, the amount shall be increased from [\*\*\*] to [\*\*\*] and (ii) Operator shall have no obligation to make such payment for any delay principally attributable to any action or omission of Delta. Delta agrees to promptly place into service within the Delta Connection Program in accordance with Delta's regular scheduling procedures such Delayed In-Service Aircraft following receipt of written certification from Operator that the aircraft is readily available and fit for service within the Delta Connection Program as contemplated by this Amendment. In addition to the foregoing, if the Delayed In- Service Aircraft is not available for service within the Delta Connection Program as contemplated by this Amendment on or before the [\*\*\*] following its Scheduled Delivery Date, then, after such [\*\*\*] and continuing until Delta receives written certification described above from Operator that the aircraft is readily available to be placed into service within the Delta Connection Program as contemplated by this Amendment, Delta shall have the right, but not the obligation, to remove such Delayed In-Service Aircraft from the scope of the Agreement upon written notice to Operator. As to matters arising with respect to the delay in such Delayed In-Service Aircraft being available for scheduled service, the foregoing represents Delta's sole and exclusive remedies attributable to such matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**C.** <u>Delay in Delivery Caused by an EMB Excusable Delay.</u> Operator hereby agrees to use commercially reasonable efforts to cause Embraer to deliver each E170+ Aircraft by no later than such E170+ Aircraft's Scheduled Delivery Date. If an E170+ Aircraft is not delivered to Operator on or before its Scheduled Delivery Date and if such delay in delivery is attributable to an EMB Excusable Delay (such E170+ Aircraft, an " <u>Excusable Delayed Aircraft</u> "), then Operator shall pay Delta an amount of [\*\*\*] during the Excusable Delay Penalty Period. Unless otherwise removed from the Agreement as provided below in this Section 3.C, the parties shall promptly determine the revised Scheduled In-Service Date following the delivery to Operator of the Excusable Delayed Aircraft. In addition to the foregoing, if the Excusable Delayed Aircraft is not delivered to Operator by Embraer on or before the [\*\*\*] following such E170+ Aircraft's Scheduled Delivery Date as a result of an EMB Excusable Delay, then either party, upon written notice to the other party delivered within [\*\*\*] following such [\*\*\*], may terminate from the scope of the Agreement such Excusable Delayed Aircraft. If either party fails to give such notice within such [\*\*\*] period, such party shall be deemed to have waived its right of termination set forth in the preceding sentence. As to matters arising with respect to the delay in the delivery of such Excusable Delayed Aircraft, the foregoing represents, as the each party, such party's sole and exclusive remedy attributable to such matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**D.** <u>Delay in Delivery Caused by an EMB Non-Excusable Delay.</u> Operator hereby agrees to use commercially reasonable efforts to cause Embraer to deliver each E170+ Aircraft by no later than such E170+ Aircraft's Scheduled Delivery Date. If an E170+ Aircraft is not delivered to Operator on or before its Scheduled Delivery Date and if such delay in delivery is attributable to an EMB Non-Excusable Delay (such E170+ Aircraft, an " <u>Non-Excusable Delayed Aircraft</u> "), then Operator shall pay Delta an amount of [\*\*\*] during the Non-Excusable Delay Penalty Period; <u>provided</u>, Operator shall have no obligation to make such payment for any delay principally attributable to any action or omission of Delta. Unless otherwise removed from the Agreement as provided below in this Section 3.D, the parties shall promptly determine the revised Scheduled In-Service Date following the delivery to Operator of the Non-Excusable Delayed Aircraft. In addition to the foregoing, if the Non-Excusable Delayed Aircraft is not delivered to Operator by Embraer on or before the [\*\*\*] following such E170+ Aircraft's Scheduled Delivery Date as a result of an EMB Non-Excusable Delay, then either

------

**EXECUTION COPY**

party, upon written notice to the other delivered within [\*\*\*] following such [\*\*\*], may terminate from the scope of the Agreement such Non-Excusable Delayed Aircraft. If either party fails to give such notice within such [\*\*\*] period, such party shall be deemed to have waived its right of termination set forth in the preceding sentence. As to matters arising with respect to the delay in the delivery of such Non-Excusable Delayed Aircraft, the foregoing represents, as the each party, such party's sole and exclusive remedy attributable to such matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**E.** <u>Delay in Delivery Caused by an Operator Caused Delay</u>. Operator hereby agrees to use commercially reasonable efforts to cause Embraer to deliver each E170+ Aircraft by no later than such E170+ Aircraft's Scheduled Delivery Date. If an E170+ Aircraft is not delivered to Operator on or before its Scheduled Delivery Date and if such delay in delivery is attributable to an Operator Caused Delay (such E170+ Aircraft, an " <u>Operator Delayed Aircraft</u> "), then Operator shall pay Delta an amount of [\*\*\*] during the Operator Caused Delay Penalty Period. Unless otherwise removed from the Agreement as provided below in this Section 3.E, the parties shall promptly determine the revised Scheduled In-Service Date following the delivery to Operator of the Operator Delayed Aircraft. In addition to the foregoing, if the Operator Delayed Aircraft is not delivered to Operator by Embraer on or before the [\*\*\*] following such E170+ Aircraft's Scheduled Delivery Date as a result of an Operator Caused Delay, then Delta shall have the right, but not the obligation, to remove such Operator Delayed Aircraft from the scope of the Agreement upon written notice to Operator. As to matters arising with respect to the delay in the delivery of such Operator Delayed Aircraft, the foregoing represents Delta's sole and exclusive remedy attributable to such matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**F.** With respect to any amounts owed to Delta pursuant to this Section 3, Delta shall be entitled to offset or recoup the full amount of any such payments from any subsequent Provisioning Payment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.** **Removal of E170+ Aircraft**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**A.** In connection with the preparation and delivery of the final monthly schedule for the E170+ Aircraft (each such monthly schedule, the "Final Monthly E170+ Schedule"), if after delivery of such schedule by Delta to Operator, Operator informs Delta in writing that Operator cannot fully operate the Final Monthly E170+ Schedule for such month for any reason that is substantially within the control of Operator (including, without limitation, crew availability) and Operator requests the removal or cancellation of scheduled flights (such requested removals and cancellations, "Operator Controlled Cancellations") or if Delta, after consultation with Operator, in good faith believes Operator cannot fully operate the Final Monthly E170+ Schedule for such month and Delta removes or cancels scheduled flights as result thereof (such removals and cancellations, "Delta Cancellations"), then, Delta shall have the right to remove from the terms of the Agreement (as modified by this Amendment) for the applicable month(s) at issue (or, at Delta's sole election, on a permanent basis), [\*\*\*] (any such E170+ Aircraft so removed, a "Removed E170+ Aircraft"). Delta shall provide written notice of such removal (temporary or permanent) within [\*\*\*] after receipt of the written notice of Operator Controlled Cancellations with respect to Operator Controlled Cancellations or, with respect to Delta Cancellations, within [\*\*\*] after delivery of the Final Monthly Schedule, whichever is applicable. With respect to any E170+ Removed Aircraft, Delta will [\*\*\*]. In determining the number of E170+ Aircraft that may be removed, fractions will be rounded up or down to the nearest whole number, with a number [\*\*\*] being rounded down to the nearest whole number. For the avoidance of doubt, (i) with respect to Operator Controlled Cancellations and Delta

------

**EXECUTION COPY**

Cancellations associated with any E170+ Aircraft that is not removed, temporarily or permanently, from the terms of the Agreement pursuant to this Section 4.A, all such cancellations shall be considered non-completed flights for purposes of the calculation of any incentives and penalties as provided in <u>Exhibit E</u> and (ii) Schedule Reduction Requests shall not be deemed Operator Controlled Cancellations or Delta Cancellations.

In preparing the Final Monthly E170+ Schedule, such schedule shall take into account scheduled maintenance for the E170+ Aircraft and, if applicable, the repair time for damaged E170+ Aircraft and accordingly, such aircraft shall not be available for scheduling during the maintenance or repair period, as applicable. For avoidance of doubt, the terms of this Section 4 shall not permit the removal (temporary or permanent) of any E170+ Aircraft from the terms of this Agreement as a result of scheduled maintenance and repair time; provided, however, notwithstanding the foregoing, if Operator is unable to operate any of the E170+ Aircraft, or any of the Delta Connection Flights, due to an E170+ Aircraft being damaged and such damage was due to an event that was substantially within the control of, or caused by, some action or inaction of Operator, Delta shall not be obligated to pay Operator any Direct Costs, or any other amounts, in connection with such non-operated E170+ Aircraft and Delta Connection Flights during the period that Operator is unable to operate such damaged E170+ Aircraft or the Delta Connection Flights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**B.** If [\*\*\*] or more E170+ Aircraft are removed on a temporary basis from the Agreement for [\*\*\*] over any [\*\*\*] rolling period, then either Delta or Operator shall, upon [\*\*\*] prior written notice to the other party, have the right to remove on a permanent basis from the terms of the Agreement the number of E170+ Aircraft that have been so removed for such [\*\*\*] period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**C.** If [\*\*\*] or more E170+ Aircraft are permanently removed from the terms of this Agreement as provided in this Section 4, then, Delta may, upon [\*\*\*] prior written notice to Operator, have the right to remove all, but not less than all, remaining E170+ Aircraft from the terms of the Agreement. If [\*\*\*] or more E170+ Aircraft are permanently removed from the terms of this Agreement as provided in this Section 4, then, Operator may, upon [\*\*\*] prior written notice to Delta, have the right to remove all, but not less than all, remaining E170+ Aircraft from the terms of the Agreement. If either party exercises its right to remove the remaining E170+ Aircraft from the terms of the Agreement as provided in this Section 4.C, the parties shall determine a mutually agreed upon wind-down schedule with respect to the remaining E170+ Aircraft, provided in no event shall such wind-down schedule be longer than [\*\*\*] after delivery of the election notice required by this Section 4.C.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**D.** If [\*\*\*] or more E170+ Aircraft are, in each case, not available to be placed into service with the Delta Connection Program as contemplated by this Amendment more than [\*\*\*] after their respective Scheduled-In Service Dates and each such delay is due to an event that was substantially within the control of, or caused by, some action or inaction of Operator or an affiliate of Operator (including, as a result of a crew shortage), then, such unavailability shall be a material breach of the Agreement by Operator and Delta may exercise any and all of its rights and remedies to which it may be entitled with respect to such material breach in accordance with the Agreement. In addition to such rights and remedies, Delta shall also have the right, but not the obligation, upon written notice to Operator to remove all E170+ Aircraft from the terms of the Agreement. In such event, the parties shall determine a mutually agreed upon wind-down schedule with respect to the E170+ Aircraft then subject to the Agreement, provided in no event shall such wind-down

------

**EXECUTION COPY**

schedule be longer than [\*\*\*] after delivery of the foregoing election notice. The foregoing termination right must be exercised within [\*\*\*] following the end of the [\*\*\*] late period of the [\*\*\*] delayed E170+ Aircraft. Failure by Delta to exercise such right within such [\*\*\*] period shall be deemed a waiver by Delta of its right of termination set forth in this Section 4.D.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**E**. [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**F.** With respect to any E170+ Aircraft that are temporarily removed from the Agreement pursuant to Section 4.A above, Operator shall not (i) operate or use any such E170+ Aircraft for itself or on behalf of any third party or (ii) lease, sublease, transfer, sell, assign or otherwise convey any interest into any such E170+ Aircraft to any third party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**5.** **Conversion .** As of the Amendment Number Twenty-Two Effective Date, each of the E170+ Aircraft is anticipated to be delivered by Embraer to Operator in a [\*\*\*]-seat configuration. Operator acknowledges that Delta may elect, in its sole discretion, to cause one or more of the E170+ Aircraft to be converted to a seating capacity in excess of [\*\*\*], but no greater than [\*\*\*]. The request for any such conversion shall be made by Delta upon at least [\*\*\*] prior written notice to Operator (or such shorter period as Embraer shall agree). The costs and expenses associated with any such conversion are as set forth in <u>Exhibit H</u> attached hereto (the "Conversion Costs"). Delta agrees that all Conversion Costs will be, at Delta's election for each converted E170+ Aircraft, either (i) Pass Through Costs for purposes of the Agreement or (ii) if done prior to the delivery of the applicable E170+ Aircraft, may be included in the Aircraft Rent/Ownership Costs as permitted pursuant to <u>Exhibit D</u>.

**E170+ Aircraft Configuration**

&nbsp;&nbsp;&nbsp;&nbsp;**1.** **STANDARD AIRCRAFT** 

The EMBRAER E170+ Aircraft (certification designation ERJ 170-200 limited to [\*\*\*] passengers) shall be manufactured according to the Technical Description which although not attached hereto, is incorporated herein by reference, and (ii) the characteristics described in the items below.

&nbsp;&nbsp;&nbsp;&nbsp;**2.** **OPTIONAL EQUIPMENT:** 

[\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;**3.** **FINISHING** 

The E170+ Aircraft will be delivered to Operator as follows:

&nbsp;&nbsp;&nbsp;&nbsp;**3.1** **EXTERIOR FINISHING:** 

The fuselage of the E170+ Aircraft shall be painted according to the Delta Connection colour and paint scheme provided by Delta to Operator, which shall be supplied to Embraer by Operator on or before [\*\*\*] prior to the first E170+ Aircraft Contractual Delivery Date. The wings and the horizontal stabilizer shall be supplied in the standard colours, i.e., grey BAC707.

The choices of colour and paint scheme made by Operator, at the direction of Delta, shall apply to all E170+ Aircraft, unless Operator, at the direction of Delta, provides written notice of a new colour and paint scheme not less than [\*\*\*] prior to the relevant E170+ Aircraft Contractual Delivery Date.

&nbsp;&nbsp;&nbsp;&nbsp;**3.2** **INTERIOR FINISHING:** 

Operator shall inform Embraer during the customer check list definition ("CCL"), to be held no later than [\*\*\*] prior to the applicable E170+ Aircraft Contractual Delivery Date, of its choice, at the direction of Delta, of materials and colours of all and any item of interior finishing such as seat covers, carpet, floor lining on galley areas, side walls and overhead lining, galley lining and curtain, from the choices offered by and available at Embraer. In case Operator opts, at the direction of Delta, to use different materials and/or patterns, Embraer will submit to Operator, who shall provide the same to Delta, a Proposal of Major Change ("PMC") describing the impacts of such option, if any. Should Operator, at the direction of Delta, not approve such PMC, the interior shall be built according to the choices offered by and available at Embraer.

Once defined, for the applicable CCL the choices of interior finishing made by Operator, at the direction of Delta, shall apply to all applicable E170+ Aircraft. If Operator requires, at the direction of Delta, an interior finishing for any Aircraft that is different from the

------

**EXECUTION COPY**

original one informed to Embraer, Operator shall present a written request to Embraer not less than [\*\*\*] prior to the relevant E170+ Aircraft Contractual Delivery Date and Embraer will submit the relevant quotation to the approval of Operator within [\*\*\*] from the date such request is received by Embraer. Should Operator, at the direction of Delta, not approve the quotation, the interior of relevant Aircraft shall be built according to the original choice of Operator.

&nbsp;&nbsp;&nbsp;&nbsp;**3.3** **BUYER FURNISHED EQUIPMENT (BFE) AND BUYER INSTALLED EQUIPMENT (BIE):** 

Operator, at the direction of Delta, may choose to have carpets, tapestries, seat covers and curtain fabrics supplied to Embraer for installation in the Aircraft as BFE. Materials shall conform to the required standards and comply with all applicable regulations and airworthiness requirements. Delays in the delivery of BFE equipment or quality restrictions that prevent the installation thereof in the time frame required by the E170+ Aircraft manufacturing process shall entitle Embraer to either delay the delivery of the E170+ Aircraft for a period related to the delay of the BFE or present the E170+ Aircraft to Operator without such BFE, in which case Operator shall not be entitled to refuse acceptance of the E170+ Aircraft.

All BFE equipment shall be delivered in DDP conditions (INCOTERMS 2010) to C&D Zodiac – 14 Centerpointe Drive, La Palma, CA 90623, USA, or to another place to be timely informed by Embraer.

Galley inserts (such as coffee makers, water boilers, ovens), trolleys and standard units and medical kits, defibrillators and wheelchairs, as well as any other equipment classified as medical or pharmaceutical product, shall be acquired by Operator and installed on the E170+ Aircraft by Operator after delivery thereof as BIE.

Notwithstanding the above, Operator shall deliver in DDP conditions (INCOTERMS 2010) to C&D Zodiac one full set of galley inserts (such as coffee makers, water boilers, ovens) for installation solely in the first Aircraft as BFE.

**Conversion Costs – E170+ Aircraft**

&nbsp;&nbsp;&nbsp;&nbsp;**1.** **SERVICE BULLETIN TO CONVERT THE INTERIOR CONFIGURATION TO** [\*\*\*] **PASSENGERS (THE "** [\*\*\*] **PAX SB")** 

&nbsp;&nbsp;&nbsp;&nbsp;1.1 In accordance with Section 5 of this Amendment, if, after an E170+ Aircraft is delivered, Delta elects to convert such E170+ Aircraft to any other configuration allowing an additional number of passengers (limited to [\*\*\*] passenger seats and provided that the additional seats have the same specification as those seats already installed in such E170+ Aircraft delivered), Operator shall cause such conversion to be completed, provided such conversion shall be done solely via a service bulletin approved by the FAA.

&nbsp;&nbsp;&nbsp;&nbsp;1.2 The aggregate price of such conversion, including all materials, parts and labor at a rate of USD $[\*\*\*] per man hour in [\*\*\*] economic conditions, up to a limit of the number of man hours to complete the required task as stated in such service bulletin (the "[\*\*\*] Pax SB") is USD [\*\*\*] ([\*\*\*] pricing [\*\*\*]), and is otherwise subject to discount as provided below.

&nbsp;&nbsp;&nbsp;&nbsp;1.3 For avoidance of doubt, if Delta elects to apply the [\*\*\*] Pax SB after the delivery of an E170+ Aircraft, then the price of the [\*\*\*] Pax SB shall have a special cumulative discount of [\*\*\*] per year, starting on the [\*\*\*] anniversary of the delivery date of such E170+ Aircraft; provided, however, that the minimum price that shall be paid by Operator for such [\*\*\*] Pax SB shall be USD $[\*\*\*] ([\*\*\*] pricing [\*\*\*]). Following the [\*\*\*] anniversary of the delivery date of such E170+ Aircraft, the discount will be applied monthly in an amount equal to [\*\*\*]. For the avoidance of doubt, the price of the [\*\*\*] Pax SB during the [\*\*\*] year after delivery of each relevant E170+ Aircraft is [\*\*\*] in [\*\*\*] pricing [\*\*\*]. Thereafter, the price will be US$ [\*\*\*] in January 2017 pricing and subject to escalation as provided in the purchase agreement between Embraer and SI, with a reduction thereafter monthly in an amount equal to [\*\*\*]% (the SB price is reduced each month by [\*\*\*]% for a total annual reduction of [\*\*\*]%).

&nbsp;&nbsp;&nbsp;&nbsp;1.4 If prior to the [\*\*\*] anniversary of the delivery of an E170+ Aircraft, Operator, at Delta's election, uses a party other than Embraer (or any affiliate of Embraer)to convert an E170+ Aircraft with a number of passenger seats above [\*\*\*], then, in addition to any amounts Operator pays such other party for such conversion, Operator shall promptly pay Embraer the price of the [\*\*\*] Pax SB that would have applied if Operator had purchased such [\*\*\*] Pax SB from Embraer, per each E170+ Aircraft that is converted by Operator using such other party.

&nbsp;&nbsp;&nbsp;&nbsp;1.5 In this <u>Exhibit H</u>, "convert" and "conversion" shall include any means of making an E170+ Aircraft have more than [\*\*\*] installed passenger seats, whether by changes to type certification, issuance of a supplemental type certificate or service bulletin, or any other means.

&nbsp;&nbsp;&nbsp;&nbsp;**2.** [\*\*\*] **PASSENGER SEATS SERVICE BULLETIN FINANCE SUPPORT** 

Should Operator request, at Delta's election, a [\*\*\*] Pax SB finance support from Embraer, the 76 Pax SB price shall be increased to [\*\*\*] in [\*\*\*] pricing [\*\*\*], with a special cumulative discount of [\*\*\*] per year, starting on the [\*\*\*] anniversary of the delivery date of the applicable E170+

**EXECUTION COPY**

Aircraft; provided, however, that the minimum price that shall be paid by Operator for such [\*\*\*] Pax SB shall be [\*\*\*] ([\*\*\*] pricing [\*\*\*]) for each E170+ Aircraft that is so converted. Following the [\*\*\*] anniversary, the discount will be applied monthly at [\*\*\*]. For the avoidance of doubt, the price of the 76 Pax SB with finance support from Embraer in the first year after delivery of each relevant E170+ Aircraft is [\*\*\*] in [\*\*\*] pricing and [\*\*\*]. At the [\*\*\*] year, the price will be [\*\*\*] in [\*\*\*] pricing [\*\*\*], with a reduction thereafter monthly at [\*\*\*] (the [\*\*\*] Pax SB price is reduced each month by [\*\*\*] for a total annual reduction of [\*\*\*]).

In connection with the monthly reconciliation process contemplated in Section 3.E of the Agreement, Operator shall identify the Substitute Item and the applicable Substituted Item and the period of substitution. For the avoidance of doubt, nothing in this Section 8 shall be deemed a waiver by Delta of the covenants and obligations of Operator set forth in Section 19.B. of the Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**9.** **Miscellaneous.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A.This Amendment constitutes the entire understanding of the parties with respect to the subject matter hereof, and any other prior or contemporaneous agreements, whether written or oral, are expressly superseded hereby.

NOW, THEREFORE, for and in consideration of the mutual undertakings set forth herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Delta and SkyWest, intending to be legally bound, hereby agree to amend the Agreement as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.** **Defined Terms.** All capitalized terms used but not defined herein shall have the meaning ascribed to such terms in the Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.** **Addition of [\*\*\*] Bombardier CRJ-900 Aircraft and Removal of [\*\*\*] Bombardier CRJ- 700 Aircraft.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Pursuant to Section 1.A.(iii) of the Agreement, the [\*\*\*] Bombardier CRJ-900 regional jet aircraft configured with [\*\*\*] passenger seats set forth in <u>Exhibit A</u> attached hereto (the " <u>[\*\*\*] CRJ-900 Aircraft</u> ") shall be added as Aircraft under, and subject to the terms and conditions of, the Agreement, as amended by this Amendment. Subject to Delta delivering to Operator the respective [\*\*\*] CRJ-900 Aircraft as contemplated in this Amendment, Operator will place each of the [\*\*\*] CRJ-900 Aircraft into service within the Delta Connection Program no later than each respective Scheduled In-Service Date as set forth in <u>Exhibit A</u> attached hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)[\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)In lieu of (x) the Engine LLP Reconciliations contemplated in Amendment Nine with respect to the Removed Pass-Through Engines (as defined in <u>Exhibit E</u> attached hereto) and (y) Engine Maintenance Expenses associated with an Overhaul Event (as defined below) with respect to the Overhaul Removed Pass-Through

**EXECUTION COPY**

Engines (as defined in <u>Exhibit E</u> attached hereto), commencing [\*\*\*] and ending through and including [\*\*\*], Delta shall pay Operator in even monthly payments $[\*\*\*] per month (total of $[\*\*\*]). Such payment will be paid as part of the monthly Provisioning Payment for the respective months. Operator agrees that costs and expenses associated with an Overhaul Event for the Overhaul Removed Pass-Through Engines shall not be treated as Pass Through Costs. For purposes of this Amendment, (A) with respect to Overhaul Removed Pass-Through Engines with manufacturer serial numbers [\*\*\*], "Overhaul Event" shall mean a scheduled event to perform an inspection of the combustion section, high pressure turbine and low pressure turbine of such Overhaul Removed Pass-Through Engine and remedy any and all deficiencies found as a result of such inspections, perform the service bulletin to modify or replace the combustion liner dome and replace the fan and low pressure turbine section life limited rotating components with new and (B) with respect to Overhaul Removed Pass-Through Engines with manufacturer serial numbers [\*\*\*], "Overhaul Event" shall mean a scheduled event to change out all life limited rotating components of such Overhaul Removed Pass- Through Engines.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4)[\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5)With respect to the Overhaul Engines (as such term is defined in Amendment Number Twenty-One to the Agreement dated effective December 1, 2016 ("<u>Amendment Twenty-One</u>")), the parties agree as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) The payments contemplated in this clause (ii) of Section 2.D of this Amendment are in addition to the Monthly Engine Operating Fee (as defined in Amendment Twenty-One).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) If as part of the removal of the Removed CRJ-700 Aircraft, an Overhaul Engine (as defined in Amendment Twenty-One) is also removed from the scope of the Agreement as contemplated in <u>Exhibit E</u> hereto prior to payment in full of the Monthly Engine Operating Fee associated with such Overhaul Engine, then, Delta shall still be obligated to pay Operator the remaining balance of the Monthly Engine Operating Fee with respect to such Overhaul Engine in accordance with the schedule set forth in Section 2 of Amendment Twenty-One.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)In connection with the removal of each of the Removed CRJ-700 Aircraft from the scope of the Agreement, Operator will remove from each Aircraft and deliver to Delta the items set forth on <u>Exhibit F</u> hereto (the "<u>Delta Returned Items</u>"), with such items being returned to Delta in "as is" "where is" condition. The Delta Returned Items will be transported to Delta at such location in the United States as Delta shall designate in writing to Operator. Risk of loss associated with the Delta Returned Items will pass to Delta upon delivery of such Delta Returned Items to the designated shipping company or to Delta,

------

**EXECUTION COPY**

whichever occurs first. [\*\*\*]. Operator shall purchase from Delta any Delta-branded cabin components not returned to Delta for an amount equal to $[\*\*\*], which shall be paid by Operator to Delta in the form of a credit against the Base Rate Costs, and such credit is reflected in the Base Rate Costs set forth on <u>Exhibit B</u> attached hereto. For avoidance of doubt, as between Operator and Delta, all other items attached to the Removed CRJ-700 Aircraft shall remain the property of Operator. In connection with the foregoing, Operator shall execute such other documents relating thereto as Delta shall reasonably request.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. (i) The Base Rate Costs to be applied to the [\*\*\*] CRJ-900 Aircraft for the entirety of their respective [\*\*\*] initial terms, [\*\*\*] shall be as set forth in <u>Exhibit B</u> attached hereto. [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Delta shall have no obligation to pay Operator the Block Hour Payment contemplated in Section 3.D of the Agreement with respect to the [\*\*\*] CRJ-900 Aircraft. For the avoidance of doubt, amounts related to the Block Hour Payment that Delta pays for other Aircraft (that are not the [\*\*\*] CRJ-900 Aircraft) under the Agreement are already included as part of the Base Rate Costs for the [\*\*\*] CRJ-900 Aircraft set forth in <u>Exhibit B</u> attached hereto. In addition, Delta shall pay Operator, or Operator shall pay Delta, as applicable, amounts related to the Performance Incentives and Penalties in accordance with, and subject to, the terms and conditions set forth in <u>Exhibit C</u> attached hereto. Operator and Delta each acknowledge and agree that (y) the performance levels provided for in <u>Exhibit C</u> shall be applicable only for the purposes of determining the corresponding incentive payments and/or penalties provided for in <u>Exhibit C</u> and may not be used for purposes of Section 11(E)(1)(v) of the Agreement and (z) Operator's unadjusted completion rate of the Delta Connection Flights scheduled to be operated by Operator with the [\*\*\*] CRJ-900 Aircraft will be included in Operator's completion rate under the Agreement for purposes of Section 11(E)(1)(v) of the Agreement. Delta and Operator covenant and agree to meet and discuss, in good faith, potential adjustments to the performance metrics and performance incentives and penalties applied to the [\*\*\*] CRJ-900 Aircraft. Delta and Operator acknowledge and agree that such performance metrics and performance incentives and penalties, when mutually agreed, shall be applied to the [\*\*\*] CRJ-900 Aircraft in lieu of the performance metrics and performance incentives and penalties set forth in <u>Exhibit C</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) With respect to each [\*\*\*] CRJ-900 Aircraft engine serial number (ESN) set forth on <u>Exhibit A</u> attached hereto (the "<u>Delivery Date BBD900 Engines</u>") and [\*\*\*] engines identified in <u>Exhibit D</u> attached hereto (each, a "<u>Spare BBD900 Engine</u>", and collectively with the Delivery Date BBD900 Engines, the "<u>BBD900 Engines</u>"), "Engine Maintenance Expense" as defined in Section 3.A.(ii)(1) of the Agreement for the BBD900 Engines shall be treated as Pass Through Costs in accordance with the terms of the Agreement.

Subject to Delta's prior written consent, such consent not to be unreasonably withheld or delayed, Operator may remove and, if necessary, replace a BBD900 Engine as a result of damage or destruction of such engine. In such event <u>Exhibit A</u> or <u>Exhibit D</u> hereto shall be amended to reflect such removal and replacement, if applicable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) As to the [\*\*\*] CRJ-900 Aircraft only, the first sentence in the fifth paragraph of Section 3.E. of the Agreement shall be amended and restated as follows:

"Notwithstanding anything herein to the contrary, if SKYW is unable to operate any of the [\*\*\*] CRJ-900 Aircraft, or any of the Delta Connection Flights scheduled to be operated by any of the [\*\*\*] CRJ-900 Aircraft, due to a strike, labor dispute or work stoppage; <u>provided</u>, in each such case that such event is

------

**EXECUTION COPY**

substantially within the control of, or caused by, some action or inaction of SKYW or an affiliate of SKYW, Delta shall not be obligated to pay SKYW any Direct Costs or any other amounts in connection with such non-operated [\*\*\*] CRJ-900 Aircraft and Delta Connection Flights."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) Notwithstanding the provisions of Article 1.D. of the Agreement, Delta shall use commercially reasonable efforts to schedule the [\*\*\*] CRJ-900 Aircraft in the geographic area in which the Removed CRJ-700 Aircraft operated prior to the removal of such Aircraft from the Agreement. If to a substantially material degree, the [\*\*\*] CRJ-900 Aircraft are scheduled to operate outside the geographic area in which the Removed CRJ-700 Aircraft operated prior to the removal of such Aircraft from the Agreement, such action shall not be a breach of the Agreement; provided, however, in any such event Delta and Operator will negotiate in good faith on an appropriate economic adjustment (up or down) to the Direct Costs solely to account for the geographic area in which the [\*\*\*] CRJ-900 Aircraft are scheduled to operate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. Delta shall select the vendor(s) to perform and complete all off-wing maintenance work associated with the Delivery Date BBD900 Engines and Spare BBD900 Engines in Delta's sole and absolute discretion; provided, such vendor(s) does not interfere with the operational standards or performance requirements of Operator. Operator shall select the vendor(s) to perform all other maintenance work associated with the 2018 CRJ-900 Aircraft in Operator's sole discretion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;G. Other than the last two sentences therein, the provisions of Article 3.G. of the Agreement shall not apply with respect to the operations of the 2018 CRJ-900 Aircraft.

[\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.** **Removal of [\*\*\*] CRJ-900 Aircraft**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. In connection with the preparation and delivery of the final monthly schedule for the [\*\*\*] CRJ-900 Aircraft (each such monthly schedule, the " <u>Final Monthly BBD900 Schedule</u> "), if after delivery of such schedule by Delta to Operator, Operator informs Delta in writing that Operator cannot fully operate the Final Monthly BBD900 Schedule for such month for any reason that is substantially within the control of Operator (including, without limitation, crew availability) and Operator requests the removal or cancellation of scheduled flights (such requested removals and cancellations, " <u>Operator Controlled Cancellations</u> ") or if Delta, after consultation with Operator, in good faith believes Operator cannot fully operate the Final Monthly BBD900 Schedule for such month and Delta removes or cancels scheduled flights as result thereof (such removals and cancellations, " <u>Delta Cancellations</u> "), then, Delta shall have the right to remove from the terms of the Agreement (as modified by this Amendment) for the applicable month(s) at issue (or, at Delta's sole election, on a permanent basis), [\*\*\*] (any such [\*\*\*] CRJ-900 Aircraft so removed, a " <u>Removed [\*\*\*] CRJ-900 Aircraft</u> "). Delta shall provide written notice of such removal (temporary or permanent) within [\*\*\*] after receipt of the written notice of Operator Controlled Cancellations with respect to Operator Controlled Cancellations or, with respect to Delta Cancellations, within [\*\*\*] after delivery of the Final Monthly Schedule, whichever is applicable. With respect to any permanently removed Removed [\*\*\*] CRJ-900 Aircraft, the applicable CRJ-900 Aircraft Lease shall terminate [\*\*\*] after receipt of notice from

------

**EXECUTION COPY**

Delta to Operator that such Removed [\*\*\*] CRJ-900 Aircraft has been removed from the Agreement on a permanent basis. In addition, with respect to Removed [\*\*\*] CRJ-900 Aircraft (temporary or permanent), Delta will have no obligation to pay Operator any Direct Costs associated with such aircraft for the period of removal and such aircraft and the cancelled flights associated therewith, including Operator Controlled Cancellations, Delta Cancellations and cancelled flights between the effective date of removal of any Removed [\*\*\*] CRJ-900 Aircraft and the reinstatement of such Removed [\*\*\*] CRJ-900 Aircraft into the scope of the Agreement (if applicable), shall be excluded from the calculation of any incentives and penalties as provided in <u>Exhibit C</u>; [\*\*\*]. In determining the number of [\*\*\*] CRJ-900 Aircraft that may be removed, fractions will be rounded up or down to the nearest whole number, with a number [\*\*\*] being rounded down to the nearest whole number. For the avoidance of doubt, with respect to Operator Controlled Cancellations and Delta Cancellations associated with any [\*\*\*] CRJ-900 Aircraft that is not removed, temporarily or permanently, from the terms of the Agreement pursuant to this Section 3.A, all such cancellations shall be considered non-completed flights for purposes of the calculation of any incentives and penalties as provided in <u>Exhibit C</u>. Except as otherwise provided in clauses (C) and (D) below, if Delta fails to provide the termination notice with respect to the applicable Operator Controlled Cancellations or Delta Cancellations as contemplated above, as to such cancellation, Delta shall have waived its right to terminate the Agreement as to the respective [\*\*\*] CRJ-900 Aircraft as provided in this clause (A).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. In preparing the Final Monthly BBD900 Schedule, such schedule shall take into account scheduled maintenance for the [\*\*\*] CRJ-900 Aircraft and, if applicable, the repair time for damaged [\*\*\*] CRJ-900 Aircraft and accordingly, such aircraft shall not be available for scheduling during the maintenance or repair period, as applicable. For avoidance of doubt, the terms of this Section 3 shall not permit the removal (temporary or permanent) of any [\*\*\*] CRJ-900 Aircraft from the terms of this Agreement as a result of scheduled maintenance and repair time; provided, however, notwithstanding the foregoing, if Operator is unable to operate any of the [\*\*\*] CRJ-900 Aircraft, or any of the Delta Connection Flights, due to an [\*\*\*] CRJ-900 Aircraft being damaged and such damage was due to an event that was substantially within the control of, or caused by, some action or inaction of Operator, Delta shall not be obligated to pay Operator any Direct Costs, or any other amounts, in connection with such non-operated [\*\*\*] CRJ-900 Aircraft and Delta Connection Flights during the period that Operator is unable to operate such damaged [\*\*\*] CRJ-900 Aircraft or the Delta Connection Flights [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. If one [\*\*\*] CRJ-900 Aircraft are removed on a temporary basis from the Agreement for [\*\*\*] over any [\*\*\*] rolling period, then either Delta or Operator shall, upon [\*\*\*] prior written notice to the other party, have the right to remove on a permanent basis from the terms of the Agreement the number of [\*\*\*] CRJ-900 Aircraft that have been so removed for such [\*\*\*] period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. If [\*\*\*] or more [\*\*\*] CRJ-900 Aircraft are permanently removed from the terms of this Agreement as provided in this Section 3, then, Delta may, upon [\*\*\*] prior written notice to Operator, have the right to remove all, but not less than all, remaining [\*\*\*] CRJ-900 Aircraft from the terms of the Agreement. If [\*\*\*] or more [\*\*\*] CRJ-900 Aircraft are permanently removed from the terms of this Agreement as provided in this Section 3, then, Operator may, upon [\*\*\*] prior written notice to Delta, have the right to remove all, but not less than all, remaining [\*\*\*] CRJ-900 Aircraft from the terms of the Agreement. If either party exercises its right to remove the remaining [\*\*\*] CRJ-900 Aircraft from the terms of

------

the Agreement as provided in this Section 3.D, the parties shall determine a mutually agreed upon wind-down schedule with respect to the remaining [\*\*\*] CRJ-900 Aircraft, provided in no event shall such wind-down schedule be longer than [\*\*\*] after delivery of the election notice required by this Section 3.D.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. If [\*\*\*] or more [\*\*\*] CRJ-900 Aircraft are, in each case, not available to be placed into service with the Delta Connection Program as contemplated by this Amendment more than [\*\*\*] after their respective Scheduled-In Service Dates and each such delay is due to an event that was substantially within the control of, or caused by, some action or inaction of Operator or an affiliate of Operator (including, as a result of a crew shortage), then, such unavailability shall be a material breach of the Agreement by Operator and Delta may exercise any and all of its rights and remedies to which it may be entitled with respect to such material breach in accordance with the Agreement, excluding the right to terminate the Agreement pursuant to Section 11.C. of the Agreement. In addition to such rights and remedies, Delta shall also have the right, but not the obligation, upon written notice to Operator to remove all [\*\*\*] CRJ-900 Aircraft from the terms of the Agreement. In such event, the parties shall determine a mutually agreed upon wind-down schedule with respect to the 2018 CRJ-900 Aircraft then subject to the Agreement, provided in no event shall such wind-down schedule be longer than [\*\*\*] after delivery of the foregoing election notice. The foregoing termination right must be exercised within [\*\*\*] following the end of the [\*\*\*] late period of the [\*\*\*] delayed [\*\*\*] CRJ-900 Aircraft. Failure by Delta to exercise such right within such [\*\*\*]-day period shall be deemed a waiver by Delta of its right of termination set forth in this Section 3.E. For purposes of this Section 3.E., any delay attributable to Bombardier (or any supplier of parts, including the engines, incorporated in the [\*\*\*] CRJ-900 Aircraft) shall not be considered a delay within the control of, or caused by, some action or inaction of Operator or any affiliate of Operator.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. With respect to any [\*\*\*] CRJ-900 Aircraft that are temporarily removed from the Agreement pursuant to Section 3.A above, Operator shall not (i) operate or use any such [\*\*\*] CRJ-900 Aircraft for itself or on behalf of any third party or (ii) lease, sublease, transfer, sell, assign or otherwise convey any interest into any such [\*\*\*] CRJ-900 Aircraft to any third party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. This Amendment constitutes the entire understanding of the parties with respect to the subject matter hereof, and any other prior or contemporaneous agreements, whether written or oral, are expressly superseded hereby *.* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. The Amendment may be executed in any number of counterparts, including via facsimile, each of which shall be deemed an original and all of which, taken together, shall constitute one and the same instrument.

WHEREAS, Delta and SkyWest desire to amend certain provisions of the Agreement; and

NOW, THEREFORE, for and in consideration of the mutual undertakings set forth herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Delta and SkyWest, intending to be legally bound, hereby agree to amend the Agreement as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.** **Defined Terms.** All capitalized terms used but not defined herein shall have the meaning ascribed to such terms in the Agreement.

applicable E175(G2) Aircraft and (ii) the execution and delivery of a mutually agreed upon extension agreement as to the applicable E175(G2) Aircraft at least [\*\*\*] prior to the expiration of such initial term or the subsequent extension term, as the case may be, including as to the Direct Costs to be applied during the applicable extension term, each party to negotiate in good faith with respect to such extension agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**C.** Contemporaneous with the Actual In-Service Date of each E175(G2) Aircraft as an Aircraft under the Agreement, Operator shall remove from service within the Delta Connection Program [\*\*\*] CRJ-900 aircraft that is an Aircraft subject to the Agreement, together with [\*\*\*] CF34-8C5 engines (the "Removed CRJ-900 Aircraft"). The Removed CRJ-900 Aircraft (together with the removed CF34-8C5 engines) are set forth in <u>Exhibit A-1</u> attached hereto. Operator covenants and agrees that it shall not operate any Delta Connection Flights with any E175(G2) Aircraft prior to the removal of a corresponding CRJ-900 Aircraft as provided in this Section 2.C.. In no event shall a Removed CRJ-900 Aircraft operate within the Delta Connection Program on or after the Actual In-Service Date of the corresponding E175(G2) Aircraft without prior written authorization from Delta. Upon the removal of the applicable Removed CRJ-900 Aircraft from this Agreement (together with the [\*\*\*] CF34- 8C5 engines so removed) as provided in this Section 2.C., Delta shall have no further payment obligations with respect to such removed aircraft or engines with respect to any periods following such removal. Concurrent with the removal of the [\*\*\*] Removed CRJ- 900 Aircraft, CF34-8C5 engine with manufacturer's serial number [\*\*\*] will be removed as a spare engine (the "Removed Spare CF34-8C5 Engine").

Delta and Operator acknowledge that the engines identified in <u>Exhibit A-1</u> attached hereto associated with the Removed CRJ900 Aircraft bearing FAA registration numbers [\*\*\*] are not subject to Engine LLP Reconciliation (as defined in Amendment Nine to the Agreement dated as of August 1, 2012 ("Amendment Nine")). With respect to the Removed Spare CF34-8C5 Engine and engines identified in <u>Exhibit A-1</u> attached hereto associated with the [\*\*\*] Removed CRJ Aircraft other than those aircraft with FAA registration numbers [\*\*\*], such engines are subject to Engine LLP Reconciliation as contemplated in Amendment Nine (such engines, the "[\*\*\*] Reconciliation Engines"). Notwithstanding <u>Exhibit A</u> of Amendment Nine, Delta and Operator acknowledge and agree that <u>Exhibit A-2</u> attached hereto and incorporated herein sets forth the agreed upon Engine LLP Reconciliation with respect to each of the [\*\*\*] Reconciliation Engines (such amount, the "Agreed Upon Engine LLP Reconciliation Amount"), such amount not to be subject to adjustment hereafter. The Parties agree that the Agreed Upon Engine LLP Reconciliation Amount will be paid as a lump sum payment by Delta to Operator as part of the first Provisioning Payment made by Delta to Operator in [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. (i) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) <u>E175(G2) Aircraft Configuration</u>. Except as set forth in this Section 2.D.(ii), Operator shall cause Embraer to deliver each of the E175(G2) Aircraft in the configuration specified in <u>Exhibit G</u> attached hereto and incorporated herein. Delta and Operator acknowledge and agree that Delta may elect to add WiFi, on-board ovens, polycarbonate class dividers, Delta- branded placarding, and/or Delta-branded passenger service unit lenses (each, an "Add-On Item") to the E175(G2) Aircraft, and if Delta makes any such election Operator shall procure each such Add-On Item from a third party vendor selected by Delta in its sole discretion, [\*\*\*]. Unless Delta notifies Operator that Delta has selected a third party vendor to install any of the Add-On Items on the E175(G2) Aircraft, Operator shall install (or, as to the WiFi

------

**Execution Copy**

only, cause a third party vendor to install) the Add-On Items on the E175(G2) Aircraft prior to each such aircraft's respective Actual In-Service Date [\*\*\*]. As to the WiFi, installation requires [\*\*\*]. Accordingly, the references to [\*\*\*] in <u>Exhibit A</u> hereto and in Section 2(D)(i) above shall, in each case, be increased to [\*\*\*] if Delta elects to add the WiFi to the E175(G2) Aircraft. Any delay caused by Delta or any such third party vendor selected by Delta with respect to the procurement or installation of any Add-On Item shall (i) be deemed due to an event that was substantially within the control of, or caused by, some action or inaction of Delta for purposes of Section 2.D.(i), and (ii) be deemed principally attributable to an action of Delta for purposes of Section 3.B of this Amendment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. (i)&nbsp;&nbsp;&nbsp;&nbsp;The Base Rate Costs to be applied to the E175(G2) Aircraft for the entirety of their respective [\*\*\*], shall be as set forth in <u>Exhibit B</u> attached hereto. [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)&nbsp;&nbsp;&nbsp;&nbsp;Delta shall have no obligation to pay Operator the Block Hour Payment contemplated in Section 3.D of the Agreement with respect to the E175(G2) Aircraft. For the avoidance of doubt, amounts related to the Block Hour Payment that Delta pays for other Aircraft (that are not the E175(G2) Aircraft) under the Agreement are already included as part of the Base Rate Costs for the E175(G2) Aircraft set forth in <u>Exhibit B</u> attached hereto. In addition, Delta shall pay Operator, or Operator shall pay Delta, as applicable, amounts related to the Performance Incentives and Penalties in accordance with, and subject to, the terms and conditions set forth in <u>Exhibit E</u> attached hereto. Operator and Delta each acknowledge and agree that (y) the performance levels provided for in <u>Exhibit E</u> shall be applicable only for the purposes of determining the corresponding incentive payments and/or penalties provided for in <u>Exhibit E</u> and may not be used for purposes of Section 11(E)(1)(v) of the Agreement and (z) Operator's unadjusted completion rate of the Delta Connection Flights scheduled to be operated by Operator with the E175(G2) Aircraft will be included in Operator's completion rate under the Agreement for purposes of Section 11(E)(1)(v) of the Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)&nbsp;&nbsp;&nbsp;&nbsp;With respect to each E175(G2) Aircraft engine serial number (ESN) set forth on <u>Exhibit A</u> attached hereto (the "Delivery Date E175(G2) Engines") and [\*\*\*] engines identified in <u>Exhibit F</u> attached hereto (each, a "Spare E175(G2) Engine", and collectively with the Delivery Date E175(G2) Engines, the "E175(G2) Engines"), "Engine Maintenance Expense" as defined in Section 3.A.(ii)(1) of the Agreement for the E175(G2) Engines shall be as provided in <u>Exhibit C</u> attached hereto; provided, in all events, such costs shall not be treated as a Pass Through Cost but shall be deemed a Base Rate Cost for purposes of the Agreement. [\*\*\*].

The E175 Engines (as defined in Amendment Number Fifteen to the Agreement dated as of October 19, 2015 ("Amendment Number Fifteen"), the E170+ Engines (as defined in Amended and Restated Amendment Number Twenty-Two dated as of September 7, 2017 ("Amendment Number Twenty-Two")) and the E175(G2) Engines shall be used only for the operation of any E175 Aircraft (as defined in Amendment Number Fifteen), any E170+ Aircraft (as defined in Amendment Number Twenty-Two) and any E175(G2) Aircraft, in each case, in connection with the Delta Connection Program. Operator shall at all times during the respective E175(G2) Aircraft Term, the E175 Aircraft Term (as defined in Amendment Number Fifteen) and the E170+ Aircraft Term (as defined in Amendment Number Twenty-Two) maintain a sufficient number of Spare E175 Engines (as defined in Amendment Number Fifteen), Spare E170+ Engines (as defined in Amendment Number Twenty-Two) and Spare E175(G2) Engines to operate, as contemplated by this Amendment, all of the E175 Aircraft, E170+ Aircraft and E175(G2) Aircraft under the scope of the Agreement at such time. In the event Operator needs additional spare engines in order to

------

**Execution Copy**

maintain a sufficient number of spare engines for the E175 Aircraft, E170+ Aircraft and the E175(G2) Aircraft, upon written notice to Delta, Operator may include additional spare engines as Spare E175 Engines, Spare E170+ Engines or Spare E175(G2) Engines as applicable, under the terms of the Agreement and <u>Exhibit F</u> shall be revised accordingly (and, as necessary, <u>Exhibit F</u> of Amendment Number Fifteen and <u>Exhibit F</u> of Amendment Number Twenty-Two).

Subject to Delta's prior written consent, such consent not to be unreasonably withheld or delayed, Operator may remove and, if necessary, replace an E175(G2) Engine as a result of damage or destruction of such engine. In such event <u>Exhibit A</u> or <u>Exhibit F</u> hereto shall be amended to reflect such removal and replacement, if applicable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) &nbsp;&nbsp;&nbsp;&nbsp;Notwithstanding the definition of Aircraft Rent/Ownership Costs as set forth in Section 3.A.(ii)(2) of the Agreement, with respect to each E175(G2) Aircraft, Aircraft Rent/Ownership Costs shall be as set forth in <u>Exhibit D</u> attached hereto. [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) &nbsp;&nbsp;&nbsp;&nbsp;Notwithstanding <u>Exhibit A</u> of Amendment Number Nine, Delta and Operator acknowledge and agree that there shall be no Engine LLP Reconciliation (as defined in Amendment Number Nine) performed with respect to any E175(G2) Engine. <u>Exhibit C</u> to this Amendment sets forth the full and complete payment obligations of Delta to Operator with respect to maintenance of the E175(G2) Engines.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) &nbsp;&nbsp;&nbsp;&nbsp;As to the E175(G2) Aircraft only, the first sentence in the fifth paragraph of Section 3.E. of the Agreement shall be amended and restated as follows:

"Notwithstanding anything herein to the contrary, if SKYW is unable to operate any of the E175(G2) Aircraft, or any of the Delta Connection Flights scheduled to be operated by any of the E175(G2) Aircraft, due to a strike, labor dispute or work stoppage; <u>provided</u>, in each such case that such event is substantially within the control of, or caused by, some action or inaction of SKYW or an affiliate of SKYW, Delta shall not be obligated to pay SKYW any Direct Costs or any other amounts in connection with such non-operated E175(G2) Aircraft and Delta Connection Flights."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii) &nbsp;&nbsp;&nbsp;&nbsp;[\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii)&nbsp;&nbsp;&nbsp;&nbsp;[\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ix) &nbsp;&nbsp;&nbsp;&nbsp;Notwithstanding the provisions of Article 1.D. of the Agreement, the Delta Connection Flights to be operated by the E175(G2) Aircraft shall be primarily supported by crew and maintenance bases of Operator located at airports in [\*\*\*]. As of the Amendment Number Twenty-Eight Effective Date, such crew and maintenance bases are as follows: crew bases ([\*\*\*]), line maintenance bases ([\*\*\*]) and overnight maintenance bases ([\*\*\*]). If to a material degree, the E175(G2) Aircraft are scheduled such that the crew and maintenance bases with respect to the E175(G2) Aircraft are not located in such airports, such act or omission shall not be a breach of the Agreement; provided, however, in any such event Delta and Operator will negotiate in good faith to agree on an appropriate economic adjustment (up or down) to the Direct Costs solely to account for the actual bases and/or maintenance bases used to support the Delta Connection Flights to be operated by the E175(G2) Aircraft.

**Execution Copy**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. Notwithstanding the provisions of Article 1.D. of the Agreement, if (i) Delta submits a proposed monthly schedule of Delta Connection Flights to be operated by the E175(G2) Aircraft during such month (each, a "Proposed Monthly E175(G2) Schedule") which provides for average daily scheduled utilization measured on a calendar month basis in the aggregate for the E175(G2) Aircraft fleet (taking into account scheduled maintenance) available to schedule ("Average E175(G2) Utilization") greater than an average of [\*\*\*] per E175(G2) Aircraft [\*\*\*] during the applicable month of determination (the "Maximum E175(G2) Utilization Level") and (ii) Operator, after conducting a good faith review and analysis of such Proposed Monthly E175(G2) Schedule and its crew availability for such month, determines, in good faith, that it is unable to operate the Proposed Monthly E175(G2) Schedule as provided by Delta, then, within [\*\*\*] following receipt of such Proposed Monthly E175(G2) Schedule, Operator shall have the option, upon delivering to Delta written notice, to request a reduction in such scheduled block hours in order to reduce the Average E175(G2) Utilization to the Maximum E175(G2) Utilization Level or a greater utilization level as specified by Operator (an "E175(G2) Schedule Reduction Request"). If Operator does not respond within such [\*\*\*] period, any such non-response shall be deemed a waiver by Operator of its right to request any schedule reduction with respect to such month's Proposed Monthly E175(G2) Schedule. Upon receipt of an E175(G2) Schedule Reduction Request, Delta shall amend the Proposed Monthly E175(G2) Schedule initially delivered by Delta to Operator to reduce the Average E175(G2) Utilization reflected in such Proposed Schedule to a level no greater than the Maximum E175(G2) Utilization Level or greater level as specified by Operator and such reduction shall thereafter be reflected in the applicable final monthly schedule for the E175(G2) Aircraft (a "Schedule Reduction"). Flights cancelled due to any such Schedule Reduction shall not be taken into account for any purposes under this Agreement, including, as pertaining to performance goals or other penalties provided for in <u>Exhibit E</u> attached hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;G. [\*\*\*] Operator shall provide Delta with a written statement of the actual foregoing costs for each E175(G2) Aircraft, together with accompanying support showing reasonable details of such costs. [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;H. Operator shall select the vendor(s) to perform and complete all maintenance work associated with the E175(G2) Aircraft (including all E175(G2) Engines and associated parts) in Operator's sole and absolute discretion; provided, however, if Delta requests Operator to change a vendor performing engine maintenance work with respect to the E175(G2) Engines and if [\*\*\*], then, Operator will cooperate with Delta with respect to such requested change in vendor for the E175(G2) Engine maintenance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I. Other than the last two sentences therein, the provisions of Article 3.G. of the Agreement shall not apply with respect to the operations of the E175(G2) Aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**B.** <u>Delays in Actual In-Service Date</u>. Operator hereby agrees to use commercially reasonable best efforts to cause each of the E175(G2) Aircraft to be available to be placed into service within the Delta Connection Program no later than the respective Scheduled In-Service Date (as set forth in <u>Exhibit A</u> hereto). If following the Delivery Date of the respective E175(G2) Aircraft, such aircraft is not placed in service within the Delta Connection Program by such E175(G2) Aircraft's Scheduled In-Service Date (such E175(G2) Aircraft, a " <u>Delayed In- Service Aircraft</u> "), then, during each day of the Service Delay Penalty Period, Operator shall pay Delta an amount of [\*\*\*] during the Service Delay Penalty Period; <u>provided</u>, (i) Operator is obligated at such time to pay the full Aircraft Rent/Ownership Costs (disregarding differences in timing as to any such payments under the respective financing documents) with respect to the Delayed In-Service Aircraft, and if not, the amount shall be increased from $[\*\*\*] to [\*\*\*] and (ii) Operator shall have no obligation to make such payment for any delay principally attributable to any action or omission of Delta. Delta agrees to promptly place into service within the Delta Connection Program in accordance with Delta's regular scheduling procedures such Delayed In-Service Aircraft following receipt of written certification from Operator that the aircraft is readily available and fit for service within the Delta Connection Program as contemplated by this Amendment. In addition to the foregoing, if the Delayed In-Service Aircraft is not available for service within the Delta Connection Program as contemplated by this Amendment on or before the [\*\*\*] following its Scheduled Delivery Date, then, after such [\*\*\*] and continuing until Delta receives written certification described above from Operator that the aircraft is readily available to be placed into service within the Delta Connection Program as contemplated by this Amendment, Delta shall have the right, but not the obligation, to remove such Delayed In-Service Aircraft from the scope of the Agreement upon written notice to Operator. As to matters arising with respect to the delay in such Delayed In-Service Aircraft being available for scheduled service, the foregoing represents Delta's sole and exclusive remedies attributable to such matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**C.** <u>Delay in Delivery Caused by an EMB Excusable Delay.</u> Operator hereby agrees to use commercially reasonable efforts to cause Embraer to deliver each E175(G2) Aircraft by no later than such E175(G2) Aircraft's Scheduled Delivery Date. If an E175(G2) Aircraft is not delivered to Operator on or before its Scheduled Delivery Date and if such delay in delivery is attributable to an EMB Excusable Delay (such E175(G2) Aircraft, an " <u>Excusable Delayed Aircraft</u> "), then Operator shall pay Delta an amount of [\*\*\*] during the Excusable Delay Penalty Period. Unless otherwise removed from the Agreement as provided below in this

------

**Execution Copy**

Section 3.C, the Parties shall promptly determine the revised Scheduled In-Service Date following the delivery to Operator of the Excusable Delayed Aircraft. In addition to the foregoing, if the Excusable Delayed Aircraft is not delivered to Operator by Embraer on or before the [\*\*\*] following such E175(G2) Aircraft's Scheduled Delivery Date as a result of an EMB Excusable Delay, then either Party, upon written notice to the other Party delivered within [\*\*\*] following such [\*\*\*], may terminate from the scope of the Agreement such Excusable Delayed Aircraft. If either Party fails to give such notice within such [\*\*\*] period, such Party shall be deemed to have waived its right of termination set forth in the preceding sentence. As to matters arising with respect to the delay in the delivery of such Excusable Delayed Aircraft, the foregoing represents, as the each Party, such Party's sole and exclusive remedy attributable to such matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**D.** <u>Delay in Delivery Caused by an EMB Non-Excusable Delay.</u> Operator hereby agrees to use commercially reasonable efforts to cause Embraer to deliver each E175(G2) Aircraft by no later than such E175(G2) Aircraft's Scheduled Delivery Date. If an E175(G2) Aircraft is not delivered to Operator on or before its Scheduled Delivery Date and if such delay in delivery is attributable to an EMB Non-Excusable Delay (such E175(G2) Aircraft, an " <u>Non-Excusable Delayed Aircraft</u> "), then Operator shall pay Delta an amount of [\*\*\*] during the Non- Excusable Delay Penalty Period; <u>provided</u>, Operator shall have no obligation to make such payment for any delay principally attributable to any action or omission of Delta. Unless otherwise removed from the Agreement as provided below in this Section 3.D, the Parties shall promptly determine the revised Scheduled In-Service Date following the delivery to Operator of the Non-Excusable Delayed Aircraft. In addition to the foregoing, if the Non- Excusable Delayed Aircraft is not delivered to Operator by Embraer on or before the [\*\*\*] following such E175(G2) Aircraft's Scheduled Delivery Date as a result of an EMB Non- Excusable Delay, then either Party, upon written notice to the other Party delivered within [\*\*\*] following such [\*\*\*], may terminate from the scope of the Agreement such Non- Excusable Delayed Aircraft. If either Party fails to give such notice within such [\*\*\*] period, such Party shall be deemed to have waived its right of termination set forth in the preceding sentence. As to matters arising with respect to the delay in the delivery of such Non-Excusable Delayed Aircraft, the foregoing represents, as the each Party, such Party's sole and exclusive remedy attributable to such matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**E.** <u>Delay in Delivery Caused by an Operator Caused Delay</u>. Operator hereby agrees to use commercially reasonable efforts to cause Embraer to deliver each E175(G2) Aircraft by no later than such E175(G2) Aircraft's Scheduled Delivery Date. If an E175(G2) Aircraft is not delivered to Operator on or before its Scheduled Delivery Date and if such delay in delivery is attributable to an Operator Caused Delay (such E175(G2) Aircraft, an " <u>Operator Delayed Aircraft</u> "), then Operator shall pay Delta an amount of [\*\*\*] during the Operator Caused Delay Penalty Period. Unless otherwise removed from the Agreement as provided below in this Section 3.E, the Parties shall promptly determine the revised Scheduled In-Service Date following the delivery to Operator of the Operator Delayed Aircraft. In addition to the foregoing, if the Operator Delayed Aircraft is not delivered to Operator by Embraer on or before the [\*\*\*] following such E175(G2) Aircraft's Scheduled Delivery Date as a result of an Operator Caused Delay, then Delta shall have the right, but not the obligation, to remove such Operator Delayed Aircraft from the scope of the Agreement upon written notice to Operator. As to matters arising with respect to the delay in the delivery of such Operator Delayed Aircraft, the foregoing represents Delta's sole and exclusive remedy attributable to such matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**F.** With respect to any amounts owed to Delta pursuant to this Section 3, Delta shall be entitled to offset or recoup the full amount of any such payments from any subsequent Provisioning Payment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.** **Removal of E175(G2) Aircraft**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**A.** In connection with the preparation and delivery of the final monthly schedule for the E175(G2) Aircraft (each such monthly schedule, the "Final Monthly E175(G2) Schedule"), if after delivery of such schedule by Delta to Operator, Operator informs Delta in writing that Operator cannot fully operate the Final Monthly E175(G2) Schedule for such month for any reason that is substantially within the control of Operator (including, without limitation, crew availability) and Operator requests the removal or cancellation of scheduled flights (such requested removals and cancellations, "Operator Controlled Cancellations") or if Delta, after consultation with Operator, in good faith believes Operator cannot fully operate the Final Monthly E175(G2) Schedule for such month and Delta removes or cancels scheduled flights as result thereof (such removals and cancellations, "Delta Cancellations"), then, Delta shall have the right to remove from the terms of the Agreement (as modified by this Amendment) for the applicable month(s) at issue (or, at Delta's sole election, on a permanent basis [\*\*\*] (any such E175(G2) Aircraft so removed, a "Removed E175(G2) Aircraft"). Delta shall provide written notice of such removal (temporary or permanent) within [\*\*\*] after receipt of the written notice of Operator Controlled Cancellations with respect to Operator Controlled Cancellations or, with respect to Delta Cancellations, within [\*\*\*] after delivery of the Final Monthly Schedule, whichever is applicable. With respect to any E175(G2) Removed Aircraft, Delta will [\*\*\*]. In determining the number of E175(G2) Aircraft that may be removed, fractions will be rounded up or down to the nearest whole number, with a number [\*\*\*] being rounded down to the nearest whole number. For the avoidance of doubt, (i) with respect to Operator Controlled Cancellations and Delta Cancellations associated with any E175(G2) Aircraft that is not removed, temporarily or permanently, from the terms of the Agreement pursuant to this Section 4.A, all such cancellations shall be considered non- completed flights for purposes of the calculation of any incentives and penalties as provided in <u>Exhibit E</u> and (ii) Schedule Reduction Requests shall not be deemed Operator Controlled Cancellations or Delta Cancellations.

In preparing the Final Monthly E175(G2) Schedule, such schedule shall take into account scheduled maintenance for the E175(G2) Aircraft and, if applicable, the repair time for damaged E175(G2) Aircraft and accordingly, such aircraft shall not be available for scheduling during the maintenance or repair period, as applicable. For avoidance of doubt, the terms of this Section 4 shall not permit the removal (temporary or permanent) of any E175(G2) Aircraft from the terms of this Agreement as a result of scheduled maintenance and repair time; provided, however, notwithstanding the foregoing, if Operator is unable to operate any of the E175(G2) Aircraft, or any of the Delta Connection Flights, due to an E175(G2) Aircraft being damaged and such damage was due to an event that was substantially within the control of, or caused by, some action or inaction of Operator, Delta shall not be obligated to pay Operator any Direct Costs, or any other amounts, in connection with such non-operated E175(G2) Aircraft and Delta Connection Flights during the period that Operator is unable to operate such damaged E175(G2) Aircraft or the Delta Connection Flights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**B.** If [\*\*\*] or more E175(G2) Aircraft are removed on a temporary basis from the Agreement for [\*\*\*] over any [\*\*\*] rolling period, then either Delta or Operator shall, upon [\*\*\*] prior

**Execution Copy**

written notice to the other Party, have the right to remove on a permanent basis from the terms of the Agreement the number of E175(G2) Aircraft that have been so removed for such [\*\*\*] period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**C.** If [\*\*\*] or more E175(G2) Aircraft are permanently removed from the terms of this Agreement as provided in this Section 4, then, Delta may, upon [\*\*\*] prior written notice to Operator, have the right to remove all, but not less than all, remaining E175(G2) Aircraft from the terms of the Agreement. If [\*\*\*] or more E175(G2) Aircraft are permanently removed from the terms of this Agreement as provided in this Section 4, then, Operator may, upon [\*\*\*] prior written notice to Delta, have the right to remove all, but not less than all, remaining E175(G2) Aircraft from the terms of the Agreement. If either Party exercises its right to remove the remaining E175(G2) Aircraft from the terms of the Agreement as provided in this Section 4.C, the Parties shall determine a mutually agreed upon wind-down schedule with respect to the remaining E175(G2) Aircraft, provided in no event shall such wind-down schedule be longer than [\*\*\*] after delivery of the election notice required by this Section 4.C.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**D.** If [\*\*\*] or more E175(G2) Aircraft are, in each case, not available to be placed into service with the Delta Connection Program as contemplated by this Amendment more than [\*\*\*] after their respective Scheduled-In Service Dates and each such delay is due to an event that was substantially within the control of, or caused by, some action or inaction of Operator or an affiliate of Operator (including, as a result of a crew shortage), then, such unavailability shall be a material breach of the Agreement by Operator and Delta may exercise any and all of its rights and remedies to which it may be entitled with respect to such material breach in accordance with the Agreement. In addition to such rights and remedies, Delta shall also have the right, but not the obligation, upon written notice to Operator to remove all E175(G2) Aircraft from the terms of the Agreement. In such event, the Parties shall determine a mutually agreed upon wind-down schedule with respect to the E175(G2) Aircraft then subject to the Agreement, provided in no event shall such wind- down schedule be longer than [\*\*\*] after delivery of the foregoing election notice. The foregoing termination right must be exercised within [\*\*\*] following the end of the [\*\*\*] late period of the [\*\*\*] delayed E175(G2) Aircraft.

**AMENDMENT NUMBER THIRTY to**

**AMENDED AND RESTATED DELTA CONNECTION AGREEMENT**

This Amendment Number Thirty (this "Amendment"), dated effective as of June 21, 2019 ("Amendment Number Thirty Effective Date"), to the Amended and Restated Delta Connection Agreement dated and effective September 8, 2005 (as amended from time to time, the "Agreement"), is between Delta Air Lines, Inc., 1030 Delta Boulevard, Atlanta, Georgia 30320 ("Delta"), and SkyWest Airlines, Inc. ("SkyWest" or "Operator"), 444 South River Road, St. George, Utah 84790. Delta and SkyWest each a "Party" and collectively, the "Parties".

WHEREAS, Delta and SkyWest are parties to the Agreement; and

WHEREAS, Delta and SkyWest desire to amend certain provisions of the Agreement; and

NOW, THEREFORE, for and in consideration of the mutual undertakings set forth herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Delta and SkyWest, intending to be legally bound, hereby agree to amend the Agreement as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.** **Defined Terms .** All capitalized terms used but not defined herein shall have the meaning ascribed to such terms in the Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.** **Addition of [\*\*\*] Embraer E170+ Aircraft and the Removal of [\*\*\*] CRJ-900 Aircraft .** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. (i) Pursuant to Section 1.A.(iii) of the Agreement, the [\*\*\*] Embraer E170+ (certification designation ERJ 170-200 LL) series regional jet aircraft configured with 70 passenger seats set forth in <u>Exhibit A</u> attached hereto (the "E170LL Aircraft") shall be added as Aircraft under, and subject to the terms and conditions of, the Agreement, as amended by this Amendment. Except as provided in <u>Section 3</u> of this Amendment, Operator shall make each E170LL Aircraft available to be placed into service within the Delta Connection Program no later than each respective Scheduled In-Service Date as set forth in <u>Exhibit A</u> attached hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) As provided in Section 5.A. of this Amendment, the number of [\*\*\*] CRJ-900 Aircraft (as defined in Amendment Number Twenty-Five to the Agreement dated as of June 19, 2018 ("Amendment Twenty-Five")) has been reduced from [\*\*\*] aircraft to [\*\*\*] as a result of the addition of the [\*\*\*] E170LL Aircraft. Accordingly, contemporaneous with the Actual In- Service Date (as defined below) of each E170LL Aircraft as an Aircraft under the Agreement, Operator shall remove from service within the Delta Connection Program the applicable Removed CRJ-700 Aircraft (as defined in Amendment Twenty-Five) in the same manner as contemplated in Section 2.D of Amendment Number Twenty-Five as if the E170LL Aircraft were a [\*\*\*] CRJ-900 Aircraft thereunder. Operator covenants and agrees that it shall not operate any Delta Connection Flights with any E170LL Aircraft prior to the removal of a corresponding Removed CRJ-700 Aircraft. Upon the removal of the Removed CRJ-700 Aircraft from the Agreement as provided above, Delta shall have no further obligations with respect to such Removed CRJ-700 Aircraft with respect to periods following such removal. For avoidance of doubt, (x) [\*\*\*] (y) the [\*\*\*] Removed CF34-8 Engines (as defined in Amendment Number Twenty-Five) and (z) the Delta Returned Items (as defined in Amendment Number Twenty-Five) shall remain in effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Notwithstanding anything in the Agreement to the contrary, the term for which each E170LL Aircraft shall be included as an Aircraft under the Agreement, and subject to the terms and conditions thereof, shall commence on each respective actual in-service date of operating

------

Delta Connection Flights (the "Actual In-Service Date") and terminate upon the earlier of [\*\*\*] (each such period, and any extension or renewal terms, an "E170LL Aircraft Term"). The parties acknowledge and agree that nothing in this Amendment shall affect, amend or modify the term of the Agreement, or any termination rights, with respect to any Aircraft that is not an E170LL Aircraft and the terms with respect to such other Aircraft shall remain as set forth in the Agreement as of the Amendment Number Thirty Effective Date. Except as set forth in Section 2.C. below, Delta shall have no obligation to pay or reimburse Operator any Direct Costs, Pass-Through Costs, or any other costs, associated with each E170LL Aircraft prior to the Actual In-Service Date of such E170LL Aircraft.

Notwithstanding the provisions of Article 11.A of the Agreement, Delta's extension rights with respect to the term of each E170LL Aircraft shall be limited to up to [\*\*\*] terms subject to the terms and conditions set forth in this Section 2.B. Any such extension will require (i) at least [\*\*\*] prior written notice from Delta to Operator prior to the expiration of the initial term or the subsequent extension term, as the case may be, of the applicable E170LL Aircraft and (ii) the execution and delivery of a mutually agreed upon extension agreement as to the applicable E170LL Aircraft at least [\*\*\*] prior to the expiration of such initial term or the subsequent extension term, as the case may be, including as to the Direct Costs to be applied during the applicable extension term, each party to negotiate in good faith with respect to such extension agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. (i) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) <u>E170LL Aircraft Configuration</u>. Except as set forth in this Section 2.C.(ii), Operator shall cause Embraer to deliver each of the E170LL Aircraft in the configuration specified in <u>Exhibit G</u> attached hereto and incorporated herein. Delta and Operator acknowledge and agree that Delta may elect to add WiFi, on-board ovens, polycarbonate class dividers, Delta- branded placarding, and/or Delta-branded passenger service unit lenses (each, an "Add-On Item") to the E170LL Aircraft, and if Delta makes any such election Operator shall procure each such Add-On Item from a third party vendor selected by Delta in its sole discretion, [\*\*\*]. Unless Delta notifies Operator that Delta has selected a third party vendor to install any of the Add-On Items on the E170LL Aircraft, Operator shall install (or, as to the WiFi only, cause a third party vendor to install) the Add-On Items on the E170LL Aircraft prior to each such aircraft's respective Actual In-Service Date [\*\*\*]. As to the WiFi, installation requires [\*\*\*]. Accordingly, the references to [\*\*\*] in <u>Exhibit A</u> hereto and in Section 2(C)(i) above shall, in each case, be increased to [\*\*\*] if Delta elects to add the WiFi to the E170LL Aircraft. Any delay caused by Delta or any such third party vendor selected by Delta with respect to the procurement or installation of any Add-On Item shall (i) be deemed due to an event that was substantially within the control of, or caused by, some action or inaction of Delta for purposes of Section 2.C.(i), and (ii) be deemed principally attributable to an action of Delta for purposes of Section 3.B of this Amendment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. (i) The Base Rate Costs to be applied to the E170LL Aircraft for the entirety of their respective [\*\*\*] initial terms, [\*\*\*] shall be as set forth in <u>Exhibit B</u> attached hereto. Such Base Rate Costs shall not apply to any Aircraft other than the E170LL Aircraft. [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)Delta shall have no obligation to pay Operator the Block Hour Payment contemplated in Section 3.D of the Agreement with respect to the E170LL Aircraft. For the avoidance of doubt, amounts related to the Block Hour Payment that Delta pays for other Aircraft (that are not the E170LL Aircraft) under the Agreement are already included as part of the Base Rate Costs for the E170LL Aircraft set forth in <u>Exhibit B</u> attached hereto. In addition, Delta shall

------

pay Operator, or Operator shall pay Delta, as applicable, amounts related to the Performance Incentives and Penalties in accordance with, and subject to, the terms and conditions set forth in <u>Exhibit E</u> attached hereto. Operator and Delta each acknowledge and agree that (y) the performance levels provided for in <u>Exhibit E</u> shall be applicable only for the purposes of determining the corresponding incentive payments and/or penalties provided for in <u>Exhibit E</u> and may not be used for purposes of Section 11(E)(1)(v) of the Agreement and (z) Operator's unadjusted completion rate of the Delta Connection Flights scheduled to be operated by Operator with the E170LL Aircraft will be included in Operator's completion rate under the Agreement for purposes of Section 11(E)(1)(v) of the Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)With respect to each E170LL Aircraft engine serial number (ESN) set forth on <u>Exhibit A</u> attached hereto (the "Delivery Date E170LL Engines") and the [\*\*\*] identified in <u>Exhibit F</u> attached hereto (the "Spare E170LL Engine", and collectively with the Delivery Date E170LL Engines, the "E170LL Engines"), "Engine Maintenance Expense" as defined in Section 3.A.(ii)(1) of the Agreement for the E170LL Engines shall be as provided in <u>Exhibit C</u> attached hereto; provided, in all events, such costs shall not be treated as a Pass Through Cost but shall be deemed a Base Rate Cost for purposes of the Agreement. [\*\*\*]

The EMB Engines (as defined in Amendment Twenty-Nine dated April 18, 2019 ("Amendment Number Twenty-Nine")) and the E170LL Engines shall be used only for the operation of any Embraer Fleet Aircraft (as defined in Amendment Twenty-Nine) and any E170LL Aircraft, in each case, in connection with the Delta Connection Program. Operator shall at all times during the respective E170LL Term, the E175 Aircraft Term (as defined in Amendment Number Fifteen dated as of October 19, 2015 ("Amendment Number Fifteen")), the E170+ Aircraft Term (as defined in Amended and Restated Amendment Twenty-Two dated September 7, 2017 ("Amendment Number Twenty-Two")), the E175(G2) Aircraft Term (as defined in Amendment Number Twenty-Eight dated April 10, 2019 ("Amendment Number Twenty-Eight")) and Repositioned Aircraft Term (as defined in Amendment Number Twenty-Nine) maintain a sufficient number of Spare E175 Engines (as defined in Amendment Number Fifteen), Spare E170+ Engines (as defined in Amendment Number Twenty-Two), Spare E175(G2) Engines (as defined in Amendment Number Twenty-Eight), Spare Repositioned Engines (as defined in Amendment Number Twenty-Nine) and the Spare E170LL Engine to operate, as contemplated by the Agreement and this Amendment, the Embraer Fleet Aircraft and the E170LL Aircraft under the scope of the Agreement at such time. In the event Operator needs additional spare engines in order to maintain a sufficient number of spare engines for the Embraer Fleet Aircraft and the E170LL Aircraft, upon written notice to Delta, Operator may include additional spare engines as Spare E175 Engines, Spare E170+ Engines, Spare E175(G2) Engines, Spare Repositioned Engines or Spare E170LL Engines as applicable, under the terms of the Agreement, and <u>Exhibit F</u> hereto, <u>Exhibit F</u> of Amendment Number Fifteen, <u>Exhibit F</u> of Amendment Number Twenty- Two, <u>Exhibit F</u> of Amendment Number Twenty-Eight or <u>Exhibit D</u> of Amendment Number Twenty-Nine, as the case may be, shall be revised accordingly as necessary to reflect such additional spare engines. For purposes of the Agreement, and from and after the Amendment Thirty Effective Date, the term "Embraer Fleet Engines" (as defined in Amendment Number Twenty-Nine) shall include the E170LL Engines and the term "Embraer Fleet Aircraft" shall include the E170LL Aircraft.

Subject to Delta's prior written consent, such consent not to be unreasonably withheld or delayed, Operator may remove and, if necessary, replace an E170LL Engine as a result of damage or destruction of such engine. In such event <u>Exhibit A</u> or <u>Exhibit F</u> hereto shall be amended to reflect such removal and replacement, if applicable.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv)Notwithstanding the definition of Aircraft Rent/Ownership Costs as set forth in Section 3.A.(ii)(2) of the Agreement, with respect to each E170LL Aircraft, Aircraft Rent/Ownership Costs shall be as set forth in <u>Exhibit D</u> attached hereto. [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v)[\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi)As to the E170LL Aircraft only, the first sentence in the fifth paragraph of Section 3.E. of the Agreement shall be amended and restated as follows:

"Notwithstanding anything herein to the contrary, if SKYW is unable to operate any of the E170LL Aircraft, or any of the Delta Connection Flights scheduled to be operated by any of the E170LL Aircraft, due to a strike, labor dispute or work stoppage; <u>provided</u>, in each such case that such event is substantially within the control of, or caused by, some action or inaction of SKYW or an affiliate of SKYW, Delta shall not be obligated to pay SKYW any Direct Costs or any other amounts in connection with such non-operated E170LL Aircraft and Delta Connection Flights."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii)[\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ix)Notwithstanding the provisions of Article 1.D. of the Agreement, the Delta Connection Flights to be operated by the E170LL Aircraft shall be primarily supported by crew and maintenance bases of Operator located at airports in [\*\*\*]. As of the Amendment Number Thirty Effective Date, such crew and maintenance bases are as follows: crew bases ([\*\*\*]), line maintenance bases ([\*\*\*]) and overnight maintenance bases [\*\*\*]. If to a material degree, the E170LL Aircraft are scheduled such that the crew and maintenance bases with respect to the E170LL Aircraft are not located in such airports, such act or omission shall not be a breach of the Agreement; provided, however, in any such event Delta and Operator will negotiate in good faith to agree on an appropriate economic adjustment (up or down) to the Direct Costs solely to account for the actual bases and/or maintenance bases used to support the Delta Connection Flights to be operated by the E170LL Aircraft.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. Notwithstanding the provisions of Article 1.D. of the Agreement, if (i) Delta submits a proposed monthly schedule of Delta Connection Flights to be operated by the E170LL Aircraft during such month (each, a "Proposed Monthly E170LL Schedule") which provides for average daily scheduled utilization measured on a calendar month basis in the aggregate for the E170LL Aircraft fleet (taking into account scheduled maintenance) available to schedule ("Average E170LL Utilization") greater than an average of [\*\*\*] per E170LL Aircraft [\*\*\*] during the applicable month of determination (the "Maximum E170LL Utilization Level") and (ii) Operator, after conducting a good faith review and analysis of such Proposed Monthly E170LL Schedule and its crew availability for such month, determines, in good faith, that it is unable to operate the Proposed Monthly E170LL Schedule as provided by Delta, then, within [\*\*\*] following receipt of such Proposed Monthly E170LL Schedule, Operator shall have the option, upon delivering to Delta written notice, to request a reduction in such scheduled block hours in order to reduce the Average E170LL Utilization to the Maximum E170LL Utilization Level or a greater utilization level as specified by Operator (an "E170LL Schedule Reduction Request"). If Operator does not respond within such [\*\*\*] period, any such non-response shall be deemed a waiver by Operator of its right to request any schedule reduction with respect to such month's Proposed Monthly E170LL Schedule. Upon receipt of an E170LL Schedule Reduction Request, Delta shall amend the Proposed Monthly E170LL Schedule initially delivered by Delta to Operator to reduce the Average E170LL Utilization reflected in such Proposed Schedule to a level no greater than the Maximum E170LL Utilization Level or greater level as specified by Operator and such reduction shall thereafter be reflected in the applicable final monthly schedule for the E170LL Aircraft (a "Schedule Reduction"). Flights cancelled due to any such Schedule Reduction shall not be taken into account for any purposes under this Agreement, including, as pertaining to performance goals or other penalties provided for in <u>Exhibit E</u> attached hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. [intentionally omitted].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;G. Operator shall select the vendor(s) to perform and complete all maintenance work associated with the E170LL Aircraft (including all E170LL Engines and associated parts) in Operator's sole and absolute discretion; provided, however, if Delta requests Operator to change a vendor performing engine maintenance work with respect to the E170LL Engines and if (i) [\*\*\*], (ii) [\*\*\*], (iii) such change does not interfere with the operational standards or performance requirements of Operator, and (iv) Operator is permitted under the then existing third party agreements to remove such E170LL Engines from the terms of such agreement without penalty, then, Operator will cooperate with Delta with respect to such requested change in vendor for the E170LL Engine maintenance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;H. Other than the last two sentences therein, the provisions of Article 3.G. of the Agreement shall not apply with respect to the operations of the E170LL Aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I. [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.** **Delay**

"<u>Scheduled Delivery Date</u>" means, as to each E170LL Aircraft, the last day of the Scheduled Delivery Month of such aircraft as set forth on <u>Exhibit A</u> hereto.

"<u>Service Delay Penalty Period</u>" [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. <u>Delays in Actual In-Service Date</u>. Operator hereby agrees to use commercially reasonable best efforts to cause each of the E170LL Aircraft to be available to be placed into service within the Delta Connection Program no later than the respective Scheduled In-Service Date (as set forth in <u>Exhibit A</u> hereto). If following the Delivery Date of the respective E170LL Aircraft, such aircraft is not placed in service within the Delta Connection Program by such E170LL Aircraft's Scheduled In-Service Date (such E170LL Aircraft, a " <u>Delayed In-Service Aircraft</u> "), then, during each day of the Service Delay Penalty Period, Operator shall pay Delta an amount of [\*\*\*] during the Service Delay Penalty Period; <u>provided</u>, (i) Operator is obligated at such time to pay the full Aircraft Rent/Ownership Costs (disregarding differences in timing as to any such payments under the respective financing documents) with respect to the Delayed In-Service Aircraft, and if not, the amount shall be increased from [\*\*\*] to [\*\*\*] and (ii) Operator shall have no obligation to make such payment for any delay principally attributable to any action or omission of Delta. Delta agrees to promptly place into service within the Delta Connection Program in accordance with Delta's regular scheduling procedures such Delayed In-Service Aircraft following receipt of written certification from Operator that the aircraft is readily available and fit for service within the Delta Connection Program as contemplated by this Amendment. In addition to the foregoing, if the Delayed In- Service Aircraft is not available for service within the Delta Connection Program as contemplated by this Amendment on or before the [\*\*\*] following its Scheduled Delivery Date, then, after such [\*\*\*] and continuing until Delta receives written certification described above from Operator that the aircraft is readily available to be placed into service within the Delta Connection Program as contemplated by this Amendment, Delta shall have the right, but not the obligation, to remove such Delayed In-Service Aircraft from the scope of the Agreement upon written notice to Operator. As to matters arising with respect to the delay in such Delayed In-Service Aircraft being available for scheduled service, the foregoing represents Delta's sole and exclusive remedies attributable to such matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. <u>Delay in Delivery Caused by an EMB Excusable Delay.</u> Operator hereby agrees to use commercially reasonable efforts to cause Embraer to deliver each E170LL Aircraft by no later than such E170LL Aircraft's Scheduled Delivery Date. If an E170LL Aircraft is not delivered to Operator on or before its Scheduled Delivery Date and if such delay in delivery is attributable to an EMB Excusable Delay (such E170LL Aircraft, an " <u>Excusable Delayed Aircraft</u> "), then Operator shall pay Delta an amount of [\*\*\*] during the Excusable Delay

------

Penalty Period. Unless otherwise removed from the Agreement as provided below in this Section 3.C, the Parties shall promptly determine the revised Scheduled In-Service Date following the delivery to Operator of the Excusable Delayed Aircraft. In addition to the foregoing, if the Excusable Delayed Aircraft is not delivered to Operator by Embraer on or before the [\*\*\*] following such E170LL Aircraft's Scheduled Delivery Date as a result of an EMB Excusable Delay, then either Party, upon written notice to the other Party delivered within [\*\*\*] following such [\*\*\*], may terminate from the scope of the Agreement such Excusable Delayed Aircraft. If either Party fails to give such notice within such [\*\*\*] period, such Party shall be deemed to have waived its right of termination set forth in the preceding sentence. As to matters arising with respect to the delay in the delivery of such Excusable Delayed Aircraft, the foregoing represents, as the each Party, such Party's sole and exclusive remedy attributable to such matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. <u>Delay in Delivery Caused by an EMB Non-Excusable Delay.</u> Operator hereby agrees to use commercially reasonable efforts to cause Embraer to deliver each E170LL Aircraft by no later than such E170LL Aircraft's Scheduled Delivery Date. If an E170LL Aircraft is not delivered to Operator on or before its Scheduled Delivery Date and if such delay in delivery is attributable to an EMB Non-Excusable Delay (such E170LL Aircraft, an " <u>Non-Excusable Delayed Aircraft</u> "), then Operator shall pay Delta an amount of [\*\*\*] during the Non- Excusable Delay Penalty Period; <u>provided</u>, Operator shall have no obligation to make such payment for any delay principally attributable to any action or omission of Delta. Unless otherwise removed from the Agreement as provided below in this Section 3.D, the Parties shall promptly determine the revised Scheduled In-Service Date following the delivery to Operator of the Non-Excusable Delayed Aircraft. In addition to the foregoing, if the Non- Excusable Delayed Aircraft is not delivered to Operator by Embraer on or before the [\*\*\*] following such E170LL Aircraft's Scheduled Delivery Date as a result of an EMB Non- Excusable Delay, then either Party, upon written notice to the other Party delivered within [\*\*\*] following such [\*\*\*], may terminate from the scope of the Agreement such Non- Excusable Delayed Aircraft. If either Party fails to give such notice within such [\*\*\*] period, such Party shall be deemed to have waived its right of termination set forth in the preceding sentence. As to matters arising with respect to the delay in the delivery of such Non-Excusable Delayed Aircraft, the foregoing represents, as the each Party, such Party's sole and exclusive remedy attributable to such matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. <u>Delay in Delivery Caused by an Operator Caused Delay</u>. Operator hereby agrees to use commercially reasonable efforts to cause Embraer to deliver each E170LL Aircraft by no later than such E170LL Aircraft's Scheduled Delivery Date. If an E170LL Aircraft is not delivered to Operator on or before its Scheduled Delivery Date and if such delay in delivery is attributable to an Operator Caused Delay (such E170LL Aircraft, an " <u>Operator Delayed Aircraft</u> "), then Operator shall pay Delta an amount of [\*\*\*] during the Operator Caused Delay Penalty Period. Unless otherwise removed from the Agreement as provided below in this Section 3.E, the Parties shall promptly determine the revised Scheduled In-Service Date following the delivery to Operator of the Operator Delayed Aircraft. In addition to the foregoing, if the Operator Delayed Aircraft is not delivered to Operator by Embraer on or before the [\*\*\*] following such E170LL Aircraft's Scheduled Delivery Date as a result of an Operator Caused Delay, then Delta shall have the right, but not the obligation, to remove such Operator Delayed Aircraft from the scope of the Agreement upon written notice to Operator. As to matters arising with respect to the delay in the delivery of such Operator Delayed Aircraft, the foregoing represents Delta's sole and exclusive remedy attributable to such matters.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. With respect to any amounts owed to Delta pursuant to this Section 3, Delta shall be entitled to offset or recoup the full amount of any such payments from any subsequent Provisioning Payment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.** **Removal of E170LL Aircraft**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. In connection with the preparation and delivery of the final monthly schedule for the E170LL Aircraft (each such monthly schedule, the "Final Monthly E170LL Schedule"), if after delivery of such schedule by Delta to Operator, Operator informs Delta in writing that Operator cannot fully operate the Final Monthly E170LL Schedule for such month for any reason that is substantially within the control of Operator (including, without limitation, crew availability) and Operator requests the removal or cancellation of scheduled flights (such requested removals and cancellations, "Operator Controlled Cancellations") or if Delta, after consultation with Operator, in good faith believes Operator cannot fully operate the Final Monthly E170LL Schedule for such month and Delta removes or cancels scheduled flights as result thereof (such removals and cancellations, "Delta Cancellations"), then, Delta shall have the right to remove from the terms of the Agreement (as modified by this Amendment) for the applicable month(s) at issue (or, at Delta's sole election, on a permanent basis), [\*\*\*] (any such E170LL Aircraft so removed, a "Removed E170LL Aircraft"). Delta shall provide written notice of such removal (temporary or permanent) within [\*\*\*] after receipt of the written notice of Operator Controlled Cancellations with respect to Operator Controlled Cancellations or, with respect to Delta Cancellations, within [\*\*\*] after delivery of the Final Monthly Schedule, whichever is applicable. With respect to any E170LL Removed Aircraft, Delta [\*\*\*]. In determining the number of E170LL Aircraft that may be removed, fractions will be rounded up or down to the nearest whole number, with a number [\*\*\*] being rounded down to the nearest whole number. For the avoidance of doubt, (i) with respect to Operator Controlled Cancellations and Delta Cancellations associated with any E170LL Aircraft that is not removed, temporarily or permanently, from the terms of the Agreement pursuant to this Section 4.A, all such cancellations shall be considered non-completed flights for purposes of the calculation of any incentives and penalties as provided in <u>Exhibit E</u> and (ii) Schedule Reduction Requests shall not be deemed Operator Controlled Cancellations or Delta Cancellations.

In preparing the Final Monthly E170LL Schedule, such schedule shall take into account scheduled maintenance for the E170LL Aircraft and, if applicable, the repair time for damaged E170LL Aircraft and accordingly, such aircraft shall not be available for scheduling during the maintenance or repair period, as applicable. For avoidance of doubt, the terms of this Section 4 shall not permit the removal (temporary or permanent) of any E170LL Aircraft from the terms of this Agreement as a result of scheduled maintenance and repair time; provided, however, notwithstanding the foregoing, if Operator is unable to operate any of the E170LL Aircraft, or any of the Delta Connection Flights, due to an E170LL Aircraft being damaged and such damage was due to an event that was substantially within the control of, or caused by, some action or inaction of Operator, Delta shall not be obligated to pay Operator any Direct Costs, or any other amounts, in connection with such non-operated E170LL Aircraft and Delta Connection Flights during the period that Operator is unable to operate such damaged E170LL Aircraft or the Delta Connection Flights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. If [\*\*\*] or more E170LL Aircraft are removed on a temporary basis from the Agreement for [\*\*\*] over any [\*\*\*] rolling period, then either Delta or Operator shall, upon [\*\*\*] prior written notice to the other Party, have the right to remove on a permanent basis from the

------

terms of the Agreement the number of E170LL Aircraft that have been so removed for such [\*\*\*] period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. If [\*\*\*] or more E170LL Aircraft are permanently removed from the terms of this Agreement as provided in this Section 4, then, Delta may, upon [\*\*\*] prior written notice to Operator, have the right to remove all, but not less than all, remaining E170LL Aircraft from the terms of the Agreement. If [\*\*\*] or more E170LL Aircraft are permanently removed from the terms of this Agreement as provided in this Section 4, then, Operator may, upon [\*\*\*] prior written notice to Delta, have the right to remove all, but not less than all, remaining E170LL Aircraft from the terms of the Agreement. If either Party exercises its right to remove the remaining E170LL Aircraft from the terms of the Agreement as provided in this Section 4.C, the Parties shall determine a mutually agreed upon wind-down schedule with respect to the remaining E170LL Aircraft, provided in no event shall such wind-down schedule be longer than [\*\*\*] after delivery of the election notice required by this Section 4.C.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. If [\*\*\*] or more E170LL Aircraft are, in each case, not available to be placed into service with the Delta Connection Program as contemplated by this Amendment more than [\*\*\*] after their respective Scheduled-In Service Dates and each such delay is due to an event that was substantially within the control of, or caused by, some action or inaction of Operator or an affiliate of Operator (including, as a result of a crew shortage), then, such unavailability shall be a material breach of the Agreement by Operator and Delta may exercise any and all of its rights and remedies to which it may be entitled with respect to such material breach in accordance with the Agreement. In addition to such rights and remedies, Delta shall also have the right, but not the obligation, upon written notice to Operator to remove all E170LL Aircraft from the terms of the Agreement. In such event, the Parties shall determine a mutually agreed upon wind-down schedule with respect to the E170LL Aircraft then subject to the Agreement, provided in no event shall such wind-down schedule be longer than [\*\*\*] after delivery of the foregoing election notice. The foregoing termination right must be exercised within [\*\*\*] following the end of the [\*\*\*] late period of the [\*\*\*] delayed E170LL Aircraft. Failure by Delta to exercise such right within such [\*\*\*] shall be deemed a waiver by Delta of its right of termination set forth in this Section 4.D.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**E**. [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**F.** With respect to any E170LL Aircraft that are temporarily removed from the Agreement pursuant to Section 4.A above, Operator shall not (i) operate or use any such E170LL Aircraft for itself or on behalf of any third party or (ii) lease, sublease, transfer, sell, assign or otherwise convey any interest into any such E170LL Aircraft to any third party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**5.** **Other Amendments and Agreements.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. **Conversion .** As of the Amendment Thirty Effective Date, each of the E170LL Aircraft is anticipated to be delivered by Embraer to Operator in a [\*\*\*]-seat configuration. Operator acknowledges that Delta may elect, in its sole discretion, to cause one or more of the E170LL Aircraft to be converted to a seating capacity in excess of [\*\*\*], but no greater than [\*\*\*]. The request for any such conversion shall be made by Delta upon at least [\*\*\*] prior written notice to Operator (or such shorter period as Embraer shall agree).

**E170LL Aircraft Configuration**

&nbsp;&nbsp;&nbsp;&nbsp;**1.** **STANDARD AIRCRAFT** 

The EMBRAER E170+ Aircraft (certification designation ERJ 170-200 LL) shall be manufactured according to the Technical Description, which although not attached hereto, is incorporated herein by reference, and (ii) the characteristics described in the items below.

&nbsp;&nbsp;&nbsp;&nbsp;**2.** **OPTIONAL EQUIPMENT:** 

[\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;**3.** **FINISHING** 

The E170LL Aircraft will be delivered to Operator as follows:

&nbsp;&nbsp;&nbsp;&nbsp;**3.1** **EXTERIOR FINISHING:** 

The fuselage of the E170LL Aircraft shall be painted according to the Delta Connection color and paint scheme provided by Delta to Operator, which shall be supplied to Embraer by Operator on or before [\*\*\*] prior to the first E170LL Aircraft Contractual Delivery Date. The wings and the horizontal stabilizer shall be supplied in the standard colors, i.e., grey BAC707.

The choices of colour and paint scheme made by Operator, at the direction of Delta, shall apply to all E170LL Aircraft, unless Operator, at the direction of Delta, provides written notice of a new colour and paint scheme not less than [\*\*\*] prior to the relevant E170LL Aircraft Contractual Delivery Date.

&nbsp;&nbsp;&nbsp;&nbsp;**3.2** **INTERIOR FINISHING:** 

Operator shall inform Embraer during the customer check list definition ("CCL"), to be held no later than [\*\*\*] prior to the applicable E170LL Aircraft Contractual Delivery Date (or such later date as Embraer shall agree), of its choice, at the direction of Delta, of materials and colours of all and any item of interior finishing such as seat covers, carpet, floor lining on galley areas, side walls and overhead lining, galley lining and curtain, from the choices offered by and available at Embraer. In case Operator opts, at the direction of Delta, to use different materials and/or patterns, Embraer will submit to Operator, who shall provide the same to Delta, a Proposal of Major Change ("PMC") describing the impacts of such option, if any. Should Operator, at the direction of Delta, not approve such PMC, the interior shall be built according to the choices offered by and available at Embraer.

Once defined, for the applicable CCL the choices of interior finishing made by Operator, at the direction of Delta, shall apply to all applicable E170LL Aircraft. If Operator requires, at the direction of Delta, an interior finishing for any Aircraft that is different from the original one informed to Embraer, Operator shall present a written request to Embraer not less than [\*\*\*] prior to the relevant E170LL Aircraft Contractual Delivery Date and Embraer will submit the relevant quotation to the approval of Operator within [\*\*\*] from the date such request is received by Embraer. Should Operator, at the direction of Delta, not approve the quotation, the interior of relevant Aircraft shall be built according to the original choice of Operator.

------

&nbsp;&nbsp;&nbsp;&nbsp;**3.3** **BUYER FURNISHED EQUIPMENT (BFE) AND BUYER INSTALLED EQUIPMENT (BIE):** 

Operator, at the direction of Delta, may choose to have carpets, tapestries, seat covers and curtain fabrics supplied to Embraer for installation in the Aircraft as BFE. Materials shall conform to the required standards and comply with all applicable regulations and airworthiness requirements. Delays in the delivery of BFE equipment or quality restrictions that prevent the installation thereof in the time frame required by the E170LL Aircraft manufacturing process shall entitle Embraer to either delay the delivery of the E170LL Aircraft for a period related to the delay of the BFE or present the E170LL Aircraft to Operator without such BFE, in which case Operator shall not be entitled to refuse acceptance of the E170LL Aircraft.

All BFE equipment shall be delivered in DDP conditions (INCOTERMS 2010) to C&D Zodiac – 14 Centerpointe Drive, La Palma, CA 90623, USA, or to another place to be timely informed by Embraer.

Galley inserts (such as coffee makers, water boilers, ovens), trolleys and standard units and medical kits, defibrillators and wheelchairs, as well as any other equipment classified as medical or pharmaceutical product, shall be acquired by Operator and installed on the E170LL Aircraft by Operator after delivery thereof as BIE.

Notwithstanding the above, Operator shall deliver in DDP conditions (INCOTERMS 2010) to C&D Zodiac one full set of galley inserts (such as coffee makers, water boilers, ovens) for installation solely in the first Aircraft as BFE.

With respect to Aircraft subject to the Agreement other than [\*\*\*] (such Aircraft, the "BBD Aircraft"), notwithstanding the foregoing provisions of this Section 1.D, if (i) Delta submits a proposed monthly schedule of Delta Connection Flights to be operated by the BBD Aircraft during such month (each, a "Proposed Monthly BBD Schedule") which provides for average daily scheduled utilization measured on a calendar month basis in the aggregate for the BBD Aircraft fleet (taking into account scheduled maintenance) available to schedule ("Average BBD Utilization") greater than an average of (x) [\*\*\*] per dual-class BBD Aircraft or (y) [\*\*\*] per single-class BBD Aircraft, in each case, [\*\*\*] during the applicable month of determination (the "Maximum BBD Utilization Level") and (ii) Operator, after conducting a good faith review and analysis of such Proposed Monthly BBD Schedule and its crew availability for such month, determines, in good faith, that it is unable to operate the Proposed Monthly BBD Schedule as provided by Delta, then, within [\*\*\*] following receipt of such Proposed Monthly BBD Schedule, Operator shall have the option, upon delivering to Delta written notice, to request a reduction in such scheduled block hours in order to reduce the Average BBD Utilization to the applicable Maximum BBD Utilization Level or a greater utilization level as specified by Operator (a "BBD Schedule Reduction Request").

Upon receipt of a BBD Schedule Reduction Request, Delta shall amend the Proposed Monthly BBD Schedule initially delivered by Delta to Operator to reduce the Average BBD Utilization reflected in such Proposed Monthly BBD Schedule to a level no greater than the applicable Maximum BBD Utilization Level or greater level as specified by Operator and such reduction shall thereafter be reflected in the applicable final monthly schedule for the BBD Aircraft (a "BBD Schedule Reduction"). Flights cancelled due to any such BBD Schedule Reduction shall not be taken into account for any purposes under this Agreement, including, as pertaining to performance goals or other penalties provided for in <u>Exhibit E</u> attached hereto or shall not be deemed an Operator Controlled Cancellation or a Delta Cancellation for purposes of Section 11.I. below.

"Notwithstanding anything herein to the contrary, if SKYW is unable to operate any of the Aircraft, or any of the Delta Connection Flights scheduled to be operated by any of the Aircraft, due to a strike, labor dispute or work stoppage; <u>provided</u>, in each such case that such event is substantially within the control of, or caused by, some action or inaction of SKYW or an affiliate of SKYW, Delta shall not be obligated to pay SKYW any Direct Costs, Block Hour Payment, Performance Incentives, or any other amounts in connection with such non-operated Aircraft and Delta Connection Flights. However, if SKYW is unable to operate any of the Aircraft, or any of the Delta Connection Flights, due to a strike, labor dispute, work stoppage or similar event or any other event, that is substantially within the control of, or caused by, some action or inaction of Delta or an affiliate of Delta, Delta shall be obligated to pay SKYW Direct Costs and Block Hour Payment based on the applicable Minimum Utilization Average, and SKYW's eligibility for any Performance Incentives and Penalties shall be calculated without regard to any cancellations, delays or complaints caused by or relating to such events. If SKYW is unable to operate any of the Aircraft, or any of the Delta Connection Flights, due to an event that is not substantially within the control of, or cause by, some action or inaction of either SKYW or Delta, Delta shall be obligated to pay SKYW the applicable AC Month Base Rate or Aircraft Month Base Rate, as the case may be, as stated on <u>Exhibit B</u> attached hereto, as well as a block hour payment based on the applicable monthly schedule then in effect, per the block hour rate set forth in <u>Exhibit D</u> attached to Amendment Thirty-One, Aircraft Rent/Ownership Costs, hull insurance, property taxes and heavy inspection costs for maintenance already in process prior to any such event, but not any other variable costs or Block Hour Payment with respect to such non-operated Aircraft and Delta Connection Flights during the period that SKYW is unable to operate such Aircraft or the Delta Connection Flights."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. As of [\*\*\*], Section 11 of the Agreement shall be amended by adding the following paragraph (I) after paragraph (H) of such section:

"I. <u>Removal of Aircraft of Certain Aircraft</u>. With respect to Aircraft subject to the Agreement other than [\*\*\*] (such Aircraft, the "Section 11(I) Aircraft"), the following provisions shall apply:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) In connection with the preparation and delivery of a final monthly schedule that includes one or more Section 11(I) Aircraft (each such monthly schedule, the "Final Monthly Section 11(I) Schedule"), if after delivery of such schedule by Delta to Operator, Operator informs Delta in writing that Operator cannot fully operate the Final Monthly Section 11(I) Schedule for such month for any reason that is substantially within the control of Operator (including, without limitation, crew availability) and Operator requests the removal or cancellation of scheduled flights of Section 11(I) Aircraft (such requested removals and cancellations, "Operator Controlled Cancellations") or if Delta, after consultation with Operator, in good faith believes Operator cannot fully operate the Final Monthly Section 11(I) Schedule for such month and Delta removes or cancels scheduled flights of Section 11(I)

EXECUTION VERSION

Aircraft as result thereof (such removals and cancellations, "Delta Cancellations"), then, Delta shall have the right to remove from the terms of the Agreement (as modified by this Amendment) for the applicable month(s) at issue (or, at Delta's sole election, on a permanent basis), [\*\*\*] (any such Section 11(I) Aircraft so removed, a "Removed Section 11(I) Aircraft"). Delta shall provide written notice of such removal (temporary or permanent) within [\*\*\*] after receipt of the written notice of Operator Controlled Cancellations with respect to Operator Controlled Cancellations or, with respect to Delta Cancellations, within [\*\*\*] after delivery of the Final Monthly Section 11(I) Schedule, whichever is applicable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) In preparing the Final Monthly Section 11(I) Schedule, such schedule shall take into account scheduled maintenance for the Section 11(I) Aircraft and, if applicable, the repair time for damaged Section 11(I) Aircraft and accordingly, such aircraft shall not be available for scheduling during the maintenance or repair period, as applicable. For avoidance of doubt, the terms of this Section 11(I) shall not permit the removal (temporary or permanent) of any Section 11(I) Aircraft from the terms of the Agreement as a result of scheduled maintenance and repair time; provided, however, notwithstanding the foregoing, if Operator is unable to operate any of the Section 11(I) Aircraft, or any of the Delta Connection Flights due to such Section 11(I) Aircraft being damaged and such damage was due to an event that was substantially within the control of, or caused by, some action or inaction of Operator or an affiliate of Operator, Delta shall not be obligated to pay Operator any Direct Costs, or any other amounts, in connection with such non-operated Section 11(I) Aircraft and Delta Connection Flights during the period that Operator is unable to operate such damaged Section 11(I) Aircraft or the Delta Connection Flights associated therewith.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) If [\*\*\*] or more Section 11(I) Aircraft are removed on a temporary basis from the Agreement for [\*\*\*] over any [\*\*\*] rolling period, then either Delta or Operator shall, upon [\*\*\*] prior written notice to the other Party, have the right to remove on a permanent basis from the terms of the Agreement the number of Section 11(I) Aircraft that have been so removed for such [\*\*\*] period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) If [\*\*\*] or more Section 11(I) Aircraft are permanently removed from the terms of this Agreement pursuant to clause (iii) of this Section 11(I), then, each Party shall have the right to remove all, but not less than all, remaining Section 11(I) Aircraft from the terms of the Agreement upon written notice to the other party. If either Party exercises its right to remove the remaining Section 11(I) Aircraft from the terms of the Agreement as provided in this Section 11(I)(iv), the Parties shall determine a mutually agreed upon wind- down schedule with respect to the remaining Section 11(I) Aircraft, provided in no event shall such wind-down schedule be longer than [\*\*\*] after delivery of the election notice required by this clause (iv) of this Section 11(I).

**AMENDED AND RESTATED DELTA CONNECTION AGREEMENT**

This Amendment Number Thirty-Three (this "Amendment"), dated effective as of November 1, 2019 ("Amendment Number Thirty-Three Effective Date"), to the Amended and Restated Delta Connection Agreement dated and effective September 8, 2005 (as amended from time to time, the "Agreement"), is between Delta Air Lines, Inc., 1030 Delta Boulevard, Atlanta, Georgia 30320 ("Delta"), and SkyWest Airlines, Inc. ("SkyWest" or "Operator"), 444 South River Road, St. George, Utah 84790.

WHEREAS, Delta and SkyWest are parties to the Agreement; and

WHEREAS, the parties desire to implement and define terms and conditions related to SkyWest utilizing an inflight mobile device onboard; and

NOW, THEREFORE, for and in consideration of the mutual undertakings set forth herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Delta and SkyWest, intending to be legally bound, hereby agree to amend the Agreement as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.** **Defined Terms .** All capitalized terms used but not defined herein shall have the meaning ascribed to such terms in the Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.** **Inflight Services Devices.** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Operator shall purchase one inflight mobile device for each of Operator's flight attendants along with a suitable number of spare devices, as reasonably determined by Operator, to support Operator's Delta Connection Flights. Such device shall be an [\*\*\*], equipped with a screen protector, customized and branded [\*\*\*] Case (as specified by Delta) for the [\*\*\*], and include a data plan of [\*\*\*] (each, a "Mobile Device"). Operator shall also purchase one Point of Sale Device as specified by Delta (each, a "POS Device" and collectively with the Mobile Devices, the "Inflight Devices"), for each of Operator's flight attendants along with a suitable number of spare POS Devices, as reasonably determined by Operator, to support Operator's Delta Connection Flights. Operator shall be responsible to obtain all regulatory approvals required to use the Inflight Devices on Operator's Delta Connection Flights at Operator's sole cost and expense.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. Contemporaneously with the execution and delivery of this Amendment, Operator and Delta shall enter into an Application Use Agreement (the "AUA") which shall set forth the terms and conditions with respect to Operator's use of any Delta licensed applications on the Inflight Devices.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. Operator and Delta agree that the Inflight Devices shall be used by Operator until the earlier of (i) the termination of the AUA or (ii) the termination of the Agreement (the "Device Term").

------

**Execution Copy**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. During the period commencing as of [\*\*\*] and ending [\*\*\*] (or such earlier date if the Device Term is terminated prior to [\*\*\*]) (such period the "Initial Device Term"), Delta shall pay Operator the applicable per departure rate as set forth in <u>Exhibit A</u> attached hereto (the "Device Rate") [\*\*\*]. Prior to Operator acquiring and fully deploying the Inflight Devices to all of Operator's flight attendants, and such Inflight Devices are operational and being utilized on a full-time basis, the Device Rate shall be the "No POS Device" rate set forth in <u>Exhibit A</u>. Thereafter, the Device Rate shall be the applicable "With POS Device" rate set forth in <u>Exhibit A</u>. From and after the Initial Device Term, the Device Rate shall be as provided in <u>Exhibit A</u> attached hereto.

Operator shall acquire, deploy, and fully implement the Inflight Devices to all of Operator's flight attendants by no later than [\*\*\*]. Delta shall only be obligated to pay the applicable Device Rate to Operator so long as Operator is in full compliance with the terms of the AUA, and Operator's flight attendants are actively using the Inflight Devices on all of Operator's Delta Connection Flights.

The parties acknowledge that as of [\*\*\*], Operator has acquired, deployed and fully implemented the Inflight Devices as contemplated in this Section 2.E. Accordingly, from [\*\*\*] to [\*\*\*], the Device Rate is the "No POS Device" rate set forth in <u>Exhibit A</u>.

If (A) the Device Term is terminated prior to [\*\*\*] due to (i) the AUA having been terminated by Delta pursuant to Section 7.3 of the AUA, (ii) the AUA having been terminated by SkyWest pursuant to Section 7.2 of the AUA or (iii) the AUA having been terminated pursuant to Section 7.4 of the AUA as a result of a default by Delta under the DCA or (B) Delta requires SkyWest to stop using the Licensed Application (as defined in the AUA) pursuant to Section 5.3 of the AUA, then, in either case, the parties shall meet to determine a mutually agreeable payment by Delta to Operator to fully reimburse Operator for the costs associated with Operator's acquisition of the Inflight Devices, each party acting reasonably, and such determination to be made using the same methodology used by the parties to determine the Device Rate. All Device Rates paid to Operator prior to any such termination shall be credited toward such reimbursement payment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. Operator may install on the Inflight Devices other applications selected by Operator that are not used in connection with either (x) the Licensed Application (as defined in the AUA) or (y) other applications provided to Operator by another airline (or otherwise selected by another airline) for use on the Inflight Device by Operator ((x) and (y) collectively, "SkyWest Applications"). Operator may also install on the Inflight Device other applications provided to Operator by another airline (or otherwise selected by another airlines) for use on the Inflight Device by Operator (such applications, "OAL Applications"). With respect to the installation of any OAL Applications or any SkyWest Applications used exclusively for another airline and not related to operator's technical manuals, Delta and Operator shall meet to determine a mutually agreeable reduction in the Device Rate, each party acting reasonably, and upon such agreement the Device Rate shall be reduced accordingly effective as of the installation of the applicable OAL Application(s) and/or SkyWest Application(s) onto the Inflight Device.

**AMENDMENT NUMBER THIRTY-FIVE to**

**AMENDED AND RESTATED DELTA CONNECTION AGREEMENT**

This Amendment Number Thirty-Five (this "Amendment"), dated effective as of June 9, 2021 ("Amendment Number Thirty-Five Effective Date"), to the Amended and Restated Delta Connection Agreement dated and effective September 8, 2005 (as amended from time to time, the "Agreement"), is between Delta Air Lines, Inc., 1030 Delta Boulevard, Atlanta, Georgia 30320 ("Delta"), and SkyWest Airlines, Inc. ("SkyWest" or "Operator"), 444 South River Road, St. George, Utah 84790. Delta and SkyWest each a "Party" and collectively, the "Parties".

WHEREAS, Delta and SkyWest are parties to the Agreement;

WHEREAS, Delta and SkyWest desire to amend certain provisions of the Agreement; and

NOW, THEREFORE, for and in consideration of the mutual undertakings set forth herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Delta and SkyWest, intending to be legally bound, hereby agree to amend the Agreement as follows:

**SECTION 1.** **Defined Terms.** All capitalized terms used but not defined herein shall have the meaning ascribed to such terms in the Agreement.

**SECTION 2.** **Variable Base Rate Cost Reductions.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.1The Parties have agreed to certain reductions to be applied during the [\*\*\*] Rate Reduction Period (as defined below) with respect to certain Base Rate Costs. <u>Schedule 1</u> attached hereto identifies the specific Base Rate Costs to be so adjusted during the [\*\*\*] Rate Reduction Period, together with the applicable adjusted Base Rate Costs to be applied during the [\*\*\*] Rate Reduction Period and the applicable Aircraft rate tranche to which such adjusted Base Rate Costs applies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.2During the [\*\*\*] Rate Reduction Period, except as set forth in Section 2.1 above, all other respective Base Rate Costs shall be the Base Rate Costs with respect to the applicable Aircraft as in effect immediately prior to the Amendment Number Thirty-Five Effective Date. Following the expiration of the [\*\*\*] Rate Reduction Period, the Base Rate Costs set forth in <u>Schedule 1</u> hereto shall not apply and the Base Rate Costs as in effect immediately prior to the Amendment Number Thirty-Five Effective Date shall be reinstated.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.3The Parties acknowledge and agree that the foregoing variable Base Rate Cost reductions are intended to reduce Base Rate Costs attributable to block hour rates and departure rates by $[\*\*\*] in the aggregate during the [\*\*\*] Rate Reduction Period (such amount, the "**Target Amount**"). Following the expiration of the [\*\*\*] Rate Reduction Period, the Parties will reconcile the actual reduction in Base Rate Costs attributable to block hour rates and departure rates during the [\*\*\*] Rate Reduction Period taking into account the rate reductions set forth in Section 2.1 above as compared to the Base Rate Costs attributable to block hour rates and departures rates during the [\*\*\*] Rate Reduction Period had the rate Reductions in Section 2.1 above not been in effect. The foregoing reconciliation shall be completed on or before [\*\*\*].

If the actual reduction in Base Rate Costs is less than the Target Amount, then, on or before [\*\*\*], SkyWest will pay to Delta the difference between the Target Amount and the actual reduction (or, at Delta's election, Delta may offset such difference from amounts otherwise next due to SkyWest under the Agreement).

------

EXECUTION VERSION

If the actual reduction in Base Rate Costs is more than the Target Amount, then, on or before [\*\*\*], Delta will pay to SkyWest the difference between the actual reduction and the Target Amount (or, at Delta's election, Delta may make such payment in connection with the amounts otherwise next due to SkyWest under the Agreement).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.3For purposes of this Amendment, the "[\*\*\*] **Rate Reduction Period**" means the period commencing on and including [\*\*\*] and ending on and including [\*\*\*].

**SECTION 3.** **Minimum Utilization Amendment.** Amendment Number Three to the Agreement dated July 1, 2009 ("<u>Amendment Three</u>") sets forth certain agreements of the Parties with respect to minimum utilization averages. [\*\*\*].

**SECTION 4.** **Expiration Date Extensions.** The Parties hereby agree to extend the respective "Expiration Dates" with respect to certain of the Aircraft. <u>Schedule 2</u> attached hereto sets forth the applicable "Expiration Date" for each of the Aircraft, including Aircraft subject to such extensions. Further, as a result of the foregoing extensions, the applicable Base Rate Costs are amended as of [\*\*\*], to reflect such extension period. <u>Schedule 3</u> hereto amends and restates the Base Rate Costs, effective as of [\*\*\*], for the Aircraft to reflect such extensions. For the avoidance of doubt, the Base Rate Costs set forth in <u>Schedule 3</u> in no way affect the Base Rate Costs Reductions provided for in Section 2 of this Amendment.

**SECTION 5.** **Miscellaneous.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.1This Amendment constitutes the entire understanding of the parties with respect to the subject matter hereof, and any other prior or contemporaneous agreements, whether written or oral, are expressly superseded hereby.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.2The Amendment may be executed in any number of counterparts, including via facsimile, each of which shall be deemed an original and all of which, taken together, shall constitute one and the same instrument.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.3Except as specifically stated herein, all other terms and conditions of the Agreement shall remain in full force and effect. In the event of any conflict between the terms of this Amendment and the Agreement, the terms of this Amendment shall prevail.

This Amendment Number Thirty-Six (this "Amendment"), dated effective as of August 3, 2021 ("Amendment Number Thirty-Six Effective Date"), to the Amended and Restated Delta Connection Agreement dated and effective September 8, 2005 (as amended from time to time, the "Agreement"), is between Delta Air Lines, Inc., 1030 Delta Boulevard, Atlanta, Georgia 30320 ("Delta"), and SkyWest Airlines, Inc. ("SkyWest" or "Operator"), 444 South River Road, St. George, Utah 84790. Delta and SkyWest each a "Party" and collectively, the "Parties".

WHEREAS, Delta and SkyWest are parties to the Agreement; and

WHEREAS, Delta and SkyWest desire to amend certain provisions of the Agreement; and

NOW, THEREFORE, for and in consideration of the mutual undertakings set forth herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Delta and SkyWest, intending to be legally bound, hereby agree to amend the Agreement as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.** **Defined Terms .** All capitalized terms used but not defined herein shall have the meaning ascribed to such terms in the Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.** **Addition of [\*\*\*] Bombardier CRJ-900 Aircraft .** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Pursuant to Section 1.A.(iii) of the Agreement, the [\*\*\*] CRJ900 series regional jet aircraft configured with [\*\*\*] passenger seats set forth in <u>Exhibit A</u> attached hereto (the "Short-Term CRJ900 Aircraft") shall be added as Aircraft under, and subject to the terms and conditions of, the Agreement, as amended by this Amendment. Operator shall make each Short-Term CRJ900 Aircraft available to be placed into service within the Delta Connection Program no later than each respective In-Service Date as set forth in <u>Exhibit A</u> attached hereto (each, the "Scheduled In-Service Date"). If any Short-Term CRJ900 Aircraft is not placed in service within the Delta Connection Program by its Scheduled In-Service Date (such Short-Term CRJ900 Aircraft, a " <u>Delayed In-Service Aircraft</u> "), then Operator shall pay Delta an amount of [\*\*\*]; <u>provided</u>, Operator shall have no obligation to make such payment for any delay principally attributable to any action or omission of Delta.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Notwithstanding anything in the Agreement to the contrary, the term for which each Short- Term CRJ900 Aircraft shall be included as an Aircraft under the Agreement, and subject to the terms and conditions thereof, shall commence on each respective Scheduled In-Service Date and terminate upon the earlier of [\*\*\*] (each such period, a "Short-Term CRJ900 Aircraft Term"). The parties acknowledge and agree that nothing in this Amendment shall affect, amend or modify the term of the Agreement, or any termination rights, with respect to any Aircraft that is not a Short-Term CRJ900 Aircraft and the terms with respect to such other Aircraft shall remain as set forth in the Agreement as of the Amendment Number Thirty-Six Effective Date. Delta shall have no obligation to pay or reimburse Operator any Direct Costs, Pass-Through Costs, or any other costs, associated with each Short-Term CRJ900 Aircraft prior to the Scheduled In-Service Date of such Short-Term CRJ900 Aircraft.

[\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. [\*\*\*]. Operator shall place each Short-Term CRJ900 Aircraft in the Delta Connection livery and interior standards as in effect as of the Amendment Number Thirty-Six Effective Date

**EXECUTION VERSION**

including, without limitation, cabin carpets, seat belts, seat covers, curtains, seat track covers, bin strips (if applicable) and laminates (collectively, the "Interior Standards").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. Notwithstanding Section 3.A.(ii) of the Agreement, the parties acknowledge and agree that [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. (i) The Base Rate Costs to be applied to the Short-Term CRJ900 Aircraft for the entirety of their respective Short-Term CRJ900 Aircraft Terms, shall be as set forth in <u>Exhibit B</u> attached hereto. [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Delta shall have no obligation to pay Operator the Block Hour Payment contemplated in Section 3.D of the Agreement with respect to the Short-Term CRJ900 Aircraft. For the avoidance of doubt, amounts related to the Block Hour Payment that Delta pays for other Aircraft (that are not the Short-Term CRJ900 Aircraft) under the Agreement are already included as part of the Base Rate Costs for the Short-Term CRJ900 Aircraft set forth in <u>Exhibit B</u> attached hereto. In addition, Delta shall pay Operator, or Operator shall pay Delta, as applicable, amounts related to the Performance Incentives and Penalties applicable to the CRJ-900 Aircraft fleet subject to the terms of the Agreement in accordance with, and subject to, the terms and conditions set forth in Amendment Thirty-One to the Agreement dated December 17, 2019.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) As to the Short-Term CRJ900 Aircraft only, the first sentence in the fifth paragraph of Section 3.E. of the Agreement shall be amended and restated as follows:

"Notwithstanding anything herein to the contrary, if SKYW is unable to operate any of the Short-Term CRJ900 Aircraft, or any of the Delta Connection Flights scheduled to be operated by any of the Short-Term CRJ900 Aircraft, due to a strike, labor dispute or work stoppage; <u>provided</u>, in each such case that such event is substantially within the control of, or caused by, some action or inaction of SKYW or an affiliate of SKYW, Delta shall not be obligated to pay SKYW any Direct Costs or any other amounts in connection with such non-operated Short-Term CRJ900 Aircraft and Delta Connection Flights."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) Notwithstanding the provisions of Article 1.D. of the Agreement, the Delta Connection Flights to be operated by the Short-Term CRJ900 Aircraft shall be primarily supported by crew and maintenance bases of Operator located at airports in [\*\*\*]. As of the Amendment Number Thirty-Six Effective Date, such crew and maintenance bases are as follows: crew bases ([\*\*\*]), line maintenance bases ([\*\*\*]) and overnight maintenance bases ([\*\*\*]). If to a material degree, the Short-Term CRJ900 Aircraft are scheduled such that the crew and maintenance bases with respect to the Short-Term CRJ900 Aircraft are not located in such airports, such act or omission shall not be a breach of the Agreement; provided, however, in any such event Delta and Operator will negotiate in good faith to agree on an appropriate economic adjustment (up or down) to the Direct Costs solely to account for the actual bases and/or maintenance bases used to support the Delta Connection Flights to be operated by the Short-Term CRJ900 Aircraft.

**EXECUTION VERSION**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. Notwithstanding the provisions of Article 1.D. of the Agreement, if (i) Delta submits a proposed monthly schedule of Delta Connection Flights to be operated by the Short-Term CRJ900 Aircraft during such month (each, a "Proposed Monthly Short-Term CRJ900 Schedule") which provides for average daily scheduled utilization measured on a calendar month basis in the aggregate for the Short-Term CRJ900 Aircraft fleet (taking into account scheduled maintenance) available to schedule ("Average Short-Term CRJ900 Utilization") greater than an average of [\*\*\*] per Short-Term CRJ900 Aircraft [\*\*\*] during the applicable month of determination (the "Maximum Short-Term CRJ900 Utilization Level") and (ii) Operator, after conducting a good faith review and analysis of such Proposed Monthly Short- Term CRJ900 Schedule and its crew availability for such month, determines, in good faith, that it is unable to operate the Proposed Monthly Short-Term CRJ900 Schedule as provided by Delta, then, within [\*\*\*] following receipt of such Proposed Monthly Short-Term CRJ900 Schedule, Operator shall have the option, upon delivering to Delta written notice, to request a reduction in such scheduled block hours in order to reduce the Average Short-Term CRJ900 Utilization to the Maximum Short-Term CRJ900 Utilization Level or a greater utilization level as specified by Operator (an "Short-Term CRJ900 Schedule Reduction Request"). If Operator does not respond within such [\*\*\*] period, any such non-response shall be deemed a waiver by Operator of its right to request any schedule reduction with respect to such month's Proposed Monthly Short-Term CRJ900 Schedule. Upon receipt of a Short-Term CRJ900 Schedule Reduction Request, Delta shall amend the Proposed Monthly Short-Term CRJ900 Schedule initially delivered by Delta to Operator to reduce the Average Short-Term CRJ900 Utilization reflected in such Proposed Schedule to a level no greater than the Maximum Short-Term CRJ900 Utilization Level or greater level as specified by Operator and such reduction shall thereafter be reflected in the applicable final monthly schedule for the Short-Term CRJ900 Aircraft (a "Schedule Reduction"). Flights cancelled due to any such Schedule Reduction shall not be taken into account for any purposes under this Agreement, including, as pertaining to performance goals or other penalties provided for in <u>Exhibit E</u> attached to the Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;G. Operator shall select the vendor(s) to perform and complete all maintenance work associated with the Short-Term CRJ900 Aircraft (including the engines associated therewith and associated parts) in Operator's sole and absolute discretion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I. Other than the last two sentences therein, the provisions of Article 3.G. of the Agreement shall not apply with respect to the operations of the Short-Term CRJ900 Aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;K. [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.** **Miscellaneous.** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. This Amendment constitutes the entire understanding of the parties with respect to the subject matter hereof, and any other prior or contemporaneous agreements, whether written or oral, are expressly superseded hereby.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. This Amendment may be executed in any number of counterparts, including via facsimile, each of which shall be deemed an original and all of which, taken together, shall constitute one and the same instrument.

**AMENDED AND RESTATED DELTA CONNECTION AGREEMENT**

This Amendment Number Thirty-Seven (this "Amendment"), dated effective as of August 3, 2021 ("Amendment Number Thirty-Seven Effective Date"), to the Amended and Restated Delta Connection Agreement dated and effective September 8, 2005 (as amended from time to time, the "Agreement"), is between Delta Air Lines, Inc., 1030 Delta Boulevard, Atlanta, Georgia 30320 ("Delta"), and SkyWest Airlines, Inc. ("SkyWest" or "Operator"), 444 South River Road, St. George, Utah 84790. Delta and SkyWest each a "Party" and collectively, the "Parties".

WHEREAS, Delta and SkyWest are parties to the Agreement; and

WHEREAS, Delta and SkyWest desire to amend certain provisions of the Agreement; and

NOW, THEREFORE, for and in consideration of the mutual undertakings set forth herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Delta and SkyWest, intending to be legally bound, hereby agree to amend the Agreement as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.** **Defined Terms .** All capitalized terms used but not defined herein shall have the meaning ascribed to such terms in the Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.** **Addition of [\*\*\*] Embraer E175 Aircraft and the Removal of [\*\*\*] CRJ-900 Aircraft .** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Pursuant to Section 1.A.(iii) of the Agreement, the [\*\*\*] Embraer E175 (certification designation ERJ 170-200 LR) series regional jet aircraft configured with 76 passenger seats set forth in <u>Exhibit A</u> attached hereto (the "E175(G3) Aircraft") shall be added as Aircraft under, and subject to the terms and conditions of, the Agreement, as amended by this Amendment. Except as provided in <u>Section 3</u> of this Amendment, Operator shall make each E175(G3) Aircraft available to be placed into service within the Delta Connection Program no later than each respective Scheduled In-Service Date as set forth in <u>Exhibit A</u> attached hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Notwithstanding anything in the Agreement to the contrary, the term for which each E175(G3) Aircraft shall be included as an Aircraft under the Agreement, and subject to the terms and conditions thereof, shall commence on each respective actual in-service date of operating Delta Connection Flights (the "Actual In-Service Date") and terminate upon the earlier of [\*\*\*] (each such period, and any extension or renewal terms, an "E175(G3) Aircraft Term"). The parties acknowledge and agree that nothing in this Amendment shall affect, amend or modify the term of the Agreement, or any termination rights, with respect to any Aircraft that is not an E175(G3) Aircraft and the terms with respect to such other Aircraft shall remain as set forth in the Agreement as of the Amendment Number Thirty-Seven Effective Date. Except as set forth in Section 2.D. below, Delta shall have no obligation to pay or reimburse Operator any Direct Costs, Pass-Through Costs, or any other costs, associated with each E175(G3) Aircraft prior to the Actual In-Service Date of such E175(G3) Aircraft.

Notwithstanding the provisions of Article 11.A of the Agreement, Delta's extension rights with respect to the term of each E175(G3) Aircraft shall be limited to up to [\*\*\*] additional [\*\*\*] terms subject to the terms and conditions set forth in this Section 2.B. Any such extension will require (i) at least [\*\*\*] prior written notice from Delta to Operator prior to the expiration of the initial term or the subsequent extension term, as the case may be, of the

------

**EXECUTION VERSION**

applicable E175(G3) Aircraft and (ii) the execution and delivery of a mutually agreed upon extension agreement as to the applicable E175(G3) Aircraft at least [\*\*\*] prior to the expiration of such initial term or the subsequent extension term, as the case may be, including as to the Direct Costs to be applied during the applicable extension term, each party to negotiate in good faith with respect to such extension agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. Contemporaneous with the Actual In-Service Date of each E175(G3) Aircraft as an Aircraft under the Agreement, Operator shall remove from service within the Delta Connection Program [\*\*\*] CRJ-900 aircraft that is an Aircraft subject to the Agreement, together with [\*\*\*] CF34-8C5 engines (the "Removed CRJ-900 Aircraft"). The Removed CRJ-900 Aircraft (together with the removed CF34-8C5 engines) are set forth in <u>Exhibit A-1</u> attached hereto. Operator covenants and agrees that it shall not operate any Delta Connection Flights with any E175(G3) Aircraft prior to the removal of a corresponding CRJ-900 Aircraft as provided in this Section 2.C. In no event shall a Removed CRJ-900 Aircraft operate within the Delta Connection Program on or after the Actual In-Service Date of the corresponding E175(G3) Aircraft without prior written authorization from Delta. Upon the removal of the applicable Removed CRJ-900 Aircraft from this Agreement (together with the [\*\*\*] CF34- 8C5 engines so removed) as provided in this Section 2.C., Delta shall have no further payment obligations with respect to such removed aircraft or engines with respect to any periods following such removal. Concurrent with the removal of the [\*\*\*] Removed CRJ- 900 Aircraft, one of the following CF34-8C5 engines with manufacturer's serial number [\*\*\*] will be removed as a spare engine (the "Removed Spare CF34-8C5 Engines").

Delta and Operator acknowledge that the engines identified in <u>Exhibit A-1</u> attached hereto associated with the Removed CRJ-900 Aircraft (the "Removed Installed CF34-8C5 Engines") and the Removed Spare CF34-8C5 Engines (collectively with the Removed Installed CF34-8C5 Engines, the "Removed CF34-8C5 Engines") are not subject to Engine LLP Reconciliation (as defined in Amendment Nine to the Agreement dated as of August 1, 2012 ("Amendment Nine")). Notwithstanding Article 3.A.(ii) of the Agreement, effective as of Amendment Number Thirty-Seven Effective Date, the Engine Maintenance Expense associated with the Removed CF34-8C5 Engines shall no longer be treated as a Pass Through Cost.

If prior to the removal of a Removed CF34-8C5 Engine as provided herein, such engine is subject to a Removal Event (as defined below), then, at the time of the Removal Event, the Removed CF34-8C5 Engine shall no longer be subject to the terms of the Agreement. In the event that [\*\*\*] Removed CF34-8C5 Engines are removed from the terms of this Agreement as a result of Removal Events, then, upon the removal of the [\*\*\*] Removed CF34-8C5 Engine and each subsequent (if any) Removed CF34-8C5 Engine, Operator shall promptly provide a Substitute CF34-8C5 Engine (as defined below) for use by Operator in connection with the operation of CRJ-900 Aircraft subject to the terms of the Agreement for the remaining period that such Removed CF34-8C5 Engine would have been subject to the terms of this Agreement but for the early removal. In such event, [\*\*\*] commencing with the [\*\*\*] Substitute Engine and for each subsequent Substitute Engine, Delta shall pay Operator [\*\*\*] for each actual departure of such [\*\*\*] and subsequent Substitute CF34-8C5 Engines until such Substitute CF34-8C5 Engine has been removed from service within the Delta Connection Program in accordance with this Amendment. As of the Amendment Number Thirty-Seven Effective Date, [\*\*\*] Removed CR34-8C5 Engines [\*\*\*] have been removed from the scope of the Agreement as a result of Removal Events.

------

**EXECUTION VERSION**

For purposes of the foregoing, a "Removal Event" shall mean the Removed CF34-8C5 Engine is removed from service as a result of scheduled or unscheduled maintenance event to fully restore performance in accordance with the original equipment manufacturer requirements.

For purposes of the foregoing, a "Substitute CF34-8C5 Engine" means a General Electric CF34-8C5 engine capable of operation with the CRJ-900 Aircraft and not then in-use with other Aircraft, whether as a spare or otherwise.

In addition, notwithstanding anything in the Agreement to the contrary, effective as of the Amendment Number Thirty-Seven Effective Date, the costs associated with any heavy airframe modification of the type contemplated in Section 4 of Amendment 19 shall not be treated as a Pass Through Cost as it relates to any Removed CRJ-900 Aircraft, and all such costs shall be the sole responsibility of Operator.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. (i) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) <u>E175(G3) Aircraft Configuration</u>. Except as set forth in this Section 2.D.(ii), Operator shall cause Embraer to deliver each of the E175(G3) Aircraft in the configuration specified in <u>Exhibit F</u> attached hereto and incorporated herein. Delta and Operator acknowledge and agree that Delta may elect to add WiFi, on-board ovens, polycarbonate class dividers, Delta- branded placarding, and/or Delta-branded passenger service unit lenses (each, an "Add-On Item") to the E175(G3) Aircraft, and if Delta makes any such election Operator shall procure each such Add-On Item from a third party vendor selected by Delta in its sole discretion, [\*\*\*]. Unless Delta notifies Operator that Delta has selected a third party vendor to install any of the Add-On Items on the E175(G3) Aircraft, Operator shall install (or, as to the WiFi only, cause a third party vendor to install) the Add-On Items on the E175(G3) Aircraft prior to each such aircraft's respective Actual In-Service Date [\*\*\*]. As to the WiFi, installation requires [\*\*\*]. Accordingly, the references to [\*\*\*] in <u>Exhibit A</u> hereto and in Section 2(D)(i) above shall, in each case, be increased to [\*\*\*] if Delta elects to add the WiFi to the E175(G3) Aircraft. Any delay caused by Delta or any such third party vendor selected by Delta with respect to the procurement or installation of any Add-On Item shall (i) be deemed due to an event that was substantially within the control of, or caused by, some action or inaction of Delta for purposes of Section 2.D.(i), and (ii) be deemed principally attributable to an action of Delta for purposes of Section 3.B of this Amendment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. (i) The Base Rate Costs to be applied to the E175(G3) Aircraft for the entirety of their respective [\*\*\*], shall be as set forth in <u>Exhibit B</u> attached hereto. [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Delta shall have no obligation to pay Operator the Block Hour Payment contemplated in Section 3.D of the Agreement with respect to the E175(G3) Aircraft. For the avoidance of doubt, amounts related to the Block Hour Payment that Delta pays for certain other Aircraft (that are not the E175(G3) Aircraft) under the Agreement are already included as part of the Base Rate Costs for the E175(G3) Aircraft set forth in <u>Exhibit B</u> attached hereto. In addition, Delta shall pay Operator, or Operator shall pay Delta, as applicable, amounts related to the Performance Incentives and Penalties in accordance with, and subject to, the terms and conditions set forth in Amendment Thirty-One to the Agreement dated December 17, 2019 ("Amendment Number Thirty-One").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) With respect to each E175(G3) Aircraft engine serial number (ESN) set forth on <u>Exhibit A</u> attached hereto (the "Delivery Date E175(G3) Engines") and [\*\*\*] engines identified in

------

**EXECUTION VERSION**

<u>Exhibit E</u> attached hereto (each, a "Spare E175(G3) Engine", and collectively with the Delivery Date E175(G3) Engines, the "E175(G3) Engines"), "Engine Maintenance Expense" as defined in Section 3.A.(ii)(1) of the Agreement for the E175(G3) Engines shall be as provided in <u>Exhibit C-2</u> attached hereto; provided, in all events, such costs shall not be treated as a Pass Through Cost but shall be deemed a Base Rate Cost for purposes of the Agreement. [\*\*\*]

The EMB Fleet Engines (as defined in <u>Exhibit C-1</u> attached hereto) shall be used only for the operation of any Embraer Fleet Aircraft (as defined in <u>Exhibit C-1</u> attached hereto), in each case, in connection with the Delta Connection Program. Operator shall at all times during the applicable EMB Aircraft Term (as defined in <u>Exhibit C-1</u> attached hereto) maintain a sufficient number of EMB Spare Engines (as defined in <u>Exhibit C-1</u> attached hereto) to operate, as contemplated by the Agreement and this Amendment, the Embraer Fleet Aircraft (as defined in <u>Exhibit C-1</u> attached hereto) under the scope of the Agreement at such time. In the event Operator needs additional spare engines in order to maintain a sufficient number of spare engines for the Embraer Fleet Aircraft, upon written notice to Delta, Operator may include additional spare engines as EMB Spare Engines under the terms of the Agreement, with the parties to agree upon the applicable Embraer Fleet Aircraft to associate such additional spare engines.

Subject to Delta's prior written consent, such consent not to be unreasonably withheld or delayed, Operator may remove and, if necessary, replace an E175(G3) Engine as a result of damage or destruction of such engine. In such event <u>Exhibit A</u> or <u>Exhibit E</u> hereto shall be amended to reflect such removal and replacement, if applicable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Notwithstanding the definition of Aircraft Rent/Ownership Costs as set forth in Section 3.A.(ii)(2) of the Agreement, with respect to each E175(G3) Aircraft, Aircraft Rent/Ownership Costs shall be as set forth in <u>Exhibit D</u> attached hereto. [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) As to the E175(G3) Aircraft, the first sentence in the fifth paragraph of Section 3.E. of the Agreement shall be amended and restated as follows:

"Notwithstanding anything herein to the contrary, if SKYW is unable to operate any of the E175(G3) Aircraft, or any of the Delta Connection Flights scheduled to be operated by any of the E175(G3) Aircraft, due to a strike, labor dispute or work stoppage; <u>provided</u>, in each such case that such event is substantially within the control of, or caused by, some action or inaction of SKYW or an affiliate of SKYW, Delta shall not be obligated to pay SKYW any Direct Costs or any other amounts in connection with such non-operated E175(G3) Aircraft and Delta Connection Flights."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ix) Notwithstanding the provisions of Article 1.D. of the Agreement, the Delta Connection Flights to be operated by the E175(G3) Aircraft shall be primarily supported by crew and maintenance bases of Operator located at airports in [\*\*\*]. As of the Amendment Number Thirty-Seven Effective Date, such crew and maintenance bases are as follows: crew bases ([\*\*\*]), line maintenance bases ([\*\*\*]) and overnight maintenance bases ([\*\*\*]). If to a

------

**EXECUTION VERSION**

material degree, the E175(G3) Aircraft are scheduled such that the crew and maintenance bases with respect to the E175(G3) Aircraft are not located in such airports, such act or omission shall not be a breach of the Agreement; provided, however, in any such event Delta and Operator will negotiate in good faith to agree on an appropriate economic adjustment (up or down) to the Direct Costs solely to account for the actual bases and/or maintenance bases used to support the Delta Connection Flights to be operated by the E175(G3) Aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. Notwithstanding the provisions of Article 1.D. of the Agreement, if (i) Delta submits a proposed monthly schedule of Delta Connection Flights to be operated by the E175(G3) Aircraft during such month (each, a "Proposed Monthly E175(G3) Schedule") which provides for average daily scheduled utilization measured on a calendar month basis in the aggregate for the E175(G3) Aircraft fleet (taking into account scheduled maintenance) available to schedule ("Average E175(G3) Utilization") greater than an average of [\*\*\*] per E175(G3) Aircraft [\*\*\*] during the applicable month of determination (the "Maximum E175(G3) Utilization Level") and (ii) Operator, after conducting a good faith review and analysis of such Proposed Monthly E175(G3) Schedule and its crew availability for such month, determines, in good faith, that it is unable to operate the Proposed Monthly E175(G3) Schedule as provided by Delta, then, within [\*\*\*] following receipt of such Proposed Monthly E175(G3) Schedule, Operator shall have the option, upon delivering to Delta written notice, to request a reduction in such scheduled block hours in order to reduce the Average E175(G3) Utilization to the Maximum E175(G3) Utilization Level or a greater utilization level as specified by Operator (an "E175(G3) Schedule Reduction Request"). If Operator does not respond within such [\*\*\*] period, any such non-response shall be deemed a waiver by Operator of its right to request any schedule reduction with respect to such month's Proposed Monthly E175(G3) Schedule. Upon receipt of an E175(G3) Schedule Reduction Request, Delta shall amend the Proposed Monthly E175(G3) Schedule initially delivered by Delta to Operator to reduce the Average E175(G3) Utilization reflected in such Proposed Schedule to a level no greater than the Maximum E175(G3) Utilization Level or greater level as specified by Operator and such reduction shall thereafter be reflected in the applicable final monthly schedule for the E175(G3) Aircraft (a "Schedule Reduction"). Flights cancelled due to any such Schedule Reduction shall not be taken into account for any purposes under this Agreement, including, as pertaining to Performance Incentive and Penalties as set forth in Amendment Number Thirty-One.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;G. Operator shall select the vendor(s) to perform and complete all maintenance work associated with the E175(G3) Aircraft (including all E175(G3) Engines and associated parts) in Operator's sole and absolute discretion; provided, however, if Delta requests Operator to change a vendor performing engine maintenance work with respect to the E175(G3) Engines and if [\*\*\*] then, Operator will cooperate with Delta with respect to such requested change in vendor for the E175(G3) Engine maintenance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;H. Other than the last two sentences therein, the provisions of Article 3.G. of the Agreement shall not apply with respect to the operations of the E175(G3) Aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I. [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.** **Delay** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. For purposes of this Section 3, the following terms shall have the respective meaning set forth herein:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. In connection with the preparation and delivery of the final monthly schedule for the E175(G3) Aircraft (each such monthly schedule, the "Final Monthly E175(G3) Schedule"), if after delivery of such schedule by Delta to Operator, Operator informs Delta in writing that Operator cannot fully operate the Final Monthly E175(G3) Schedule for such month for any reason that is substantially within the control of Operator (including, without limitation, crew availability) and Operator requests the removal or cancellation of scheduled flights (such requested removals and cancellations, "Operator Controlled Cancellations") or if Delta, after consultation with Operator, in good faith believes Operator cannot fully operate the Final Monthly E175(G3) Schedule for such month and Delta removes or cancels scheduled flights as result thereof (such removals and cancellations, "Delta Cancellations"), then, Delta shall have the right to remove from the terms of the Agreement (as modified by this Amendment) for the applicable month(s) at issue (or, at Delta's sole election, on a permanent basis [\*\*\*] (any such E175(G3) Aircraft so removed, a "Removed E175(G3) Aircraft"). Delta shall provide written notice of such removal (temporary or permanent) within [\*\*\*] after receipt of the written notice of Operator Controlled Cancellations with respect to Operator Controlled Cancellations or, with respect to Delta Cancellations, within [\*\*\*] after delivery of the Final Monthly Schedule, whichever is applicable. With respect to any E175(G3) Removed Aircraft, Delta will [\*\*\*]. In determining the number of E175(G3) Aircraft that may be removed, fractions will be rounded up or down to the nearest whole number, with a number [\*\*\*] being rounded down to the nearest whole number. For the avoidance of doubt, (i) with respect to Operator Controlled Cancellations and Delta Cancellations associated with any E175(G3) Aircraft that is not removed, temporarily or permanently, from the terms of the Agreement pursuant to this Section 4.A, all such cancellations shall be considered non- completed flights for purposes of the calculation of any incentives and penalties as provided in Amendment Number Thirty-One and (ii) Schedule Reduction Requests shall not be deemed Operator Controlled Cancellations or Delta Cancellations.

In preparing the Final Monthly E175(G3) Schedule, such schedule shall take into account scheduled maintenance for the E175(G3) Aircraft and, if applicable, the repair time for damaged E175(G3) Aircraft and accordingly, such aircraft shall not be available for scheduling during the maintenance or repair period, as applicable. For avoidance of doubt, the terms of this Section 4 shall not permit the removal (temporary or permanent) of any E175(G3) Aircraft from the terms of this Agreement as a result of scheduled maintenance and repair time; provided, however, notwithstanding the foregoing, if Operator is unable to operate any of the E175(G3) Aircraft, or any of the Delta Connection Flights, due to an E175(G3) Aircraft being damaged and such damage was due to an event that was substantially within the control of, or caused by, some action or inaction of Operator, Delta shall not be obligated to pay Operator any Direct Costs, or any other amounts, in connection with such non-operated E175(G3) Aircraft and Delta Connection Flights during the period that Operator is unable to operate such damaged E175(G3) Aircraft or the Delta Connection Flights.

**EXECUTION VERSION**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. If [\*\*\*] or more E175(G3) Aircraft are removed on a temporary basis from the Agreement for [\*\*\*] over any [\*\*\*] rolling period, then either Delta or Operator shall, upon [\*\*\*] prior written notice to the other Party, have the right to remove on a permanent basis from the terms of the Agreement the number of E175(G3) Aircraft that have been so removed for such [\*\*\*] period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. If [\*\*\*] or more E175(G3) Aircraft are permanently removed from the terms of this Agreement as provided in this Section 4, then, Delta may, upon [\*\*\*] prior written notice to Operator, have the right to remove all, but not less than all, remaining E175(G3) Aircraft from the terms of the Agreement. If [\*\*\*] or more E175(G3) Aircraft are permanently removed from the terms of this Agreement as provided in this Section 4, then, Operator may, upon [\*\*\*] prior written notice to Delta, have the right to remove all, but not less than all, remaining E175(G3) Aircraft from the terms of the Agreement. If either Party exercises its right to remove the remaining E175(G3) Aircraft from the terms of the Agreement as provided in this Section 4.C, the Parties shall determine a mutually agreed upon wind-down schedule with respect to the remaining E175(G3) Aircraft, provided in no event shall such wind-down schedule be longer than [\*\*\*] after delivery of the election notice required by this Section 4.C.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. If [\*\*\*] or more E175(G3) Aircraft are, in each case, not available to be placed into service with the Delta Connection Program as contemplated by this Amendment more than [\*\*\*] after their respective Scheduled-In Service Dates and each such delay is due to an event that was substantially within the control of, or caused by, some action or inaction of Operator or an affiliate of Operator (including, as a result of a crew shortage), then, such unavailability shall be a material breach of the Agreement by Operator and Delta may exercise any and all of its rights and remedies to which it may be entitled with respect to such material breach in accordance with the Agreement. In addition to such rights and remedies, Delta shall also have the right, but not the obligation, upon written notice to Operator to remove all E175(G3) Aircraft from the terms of the Agreement. In such event, the Parties shall determine a mutually agreed upon wind-down schedule with respect to the E175(G3) Aircraft then subject to the Agreement, provided in no event shall such wind- down schedule be longer than [\*\*\*] after delivery of the foregoing election notice. The foregoing termination right must be exercised within [\*\*\*] following the end of the [\*\*\*] late period of the [\*\*\*] delayed E175(G3) Aircraft. Failure by Delta to exercise such right within such [\*\*\*] period shall be deemed a waiver by Delta of its right of termination set forth in this Section 4.D.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F**.** With respect to any E175(G3) Aircraft that are temporarily removed from the Agreement pursuant to Section 4.A above, Operator shall not (i) operate or use any such E175(G3) Aircraft for itself or on behalf of any third party or (ii) lease, sublease, transfer, sell, assign or otherwise convey any interest into any such E175(G3) Aircraft to any third party.

The E175(G3) Aircraft will be delivered to Operator as follows:

&nbsp;&nbsp;&nbsp;&nbsp;**3.1** **EXTERIOR FINISHING:** 

The fuselage of the E175(G3) Aircraft shall be painted according to the Delta Connection color and paint scheme provided by Delta to Operator, which shall be supplied to Embraer by Operator on or before [\*\*\*] prior to the first E175(G3) Aircraft Contractual Delivery Date. The wings and the horizontal stabilizer shall be supplied in the standard colors, i.e., grey BAC707.

The choices of colour and paint scheme made by Operator, at the direction of Delta, shall apply to all E175(G3) Aircraft, unless Operator, at the direction of Delta, provides written notice of a new colour and paint scheme not less than [\*\*\*] prior to the relevant E175(G3) Aircraft Contractual Delivery Date.

&nbsp;&nbsp;&nbsp;&nbsp;**3.2** **INTERIOR FINISHING:** 

Operator shall inform Embraer during the customer check list definition ("CCL"), to be held no later than [\*\*\*] prior to the applicable E175(G3) Aircraft Contractual Delivery Date (or such later date as Embraer shall agree), of its choice, at the direction of Delta, of materials and colours of all and any item of interior finishing such as seat covers, carpet, floor lining on galley areas, side walls and overhead lining, galley lining and curtain, from the choices offered by and available at Embraer. In case Operator opts, at the direction of Delta, to use different materials and/or patterns, Embraer will submit to Operator, who shall provide the same to Delta, a Proposal of Major Change ("PMC") describing the impacts of such option, if any. Should Operator, at the direction of Delta, not approve such PMC, the interior shall be built according to the choices offered by and available at Embraer.

Once defined, for the applicable CCL the choices of interior finishing made by Operator, at the direction of Delta, shall apply to all applicable E175(G3) Aircraft. If Operator requires, at the direction of Delta, an interior finishing for any Aircraft that is different from the original one informed to Embraer, Operator shall present a written request to Embraer not less than [\*\*\*] prior to the relevant E175(G3) Aircraft Contractual Delivery Date and Embraer will submit the relevant quotation to the approval of Operator within [\*\*\*] from the date such request is received by Embraer. Should Operator, at the direction of Delta, not approve the quotation, the interior of relevant Aircraft shall be built according to the original choice of Operator.

**AMENDED AND RESTATED DELTA CONNECTION AGREEMENT**

This Amendment Number Thirty-Eight (this "Amendment"), dated effective as of January 12, 2022 ("Amendment Number Thirty-Eight Effective Date"), to the Amended and Restated Delta Connection Agreement dated and effective September 8, 2005 (as amended from time to time, the "Agreement"), is between Delta Air Lines, Inc., 1030 Delta Boulevard, Atlanta, Georgia 30320 ("Delta"), and SkyWest Airlines, Inc. ("SkyWest" or "Operator"), 444 South River Road, St. George, Utah 84790. Delta and SkyWest each a "Party" and collectively, the "Parties".

WHEREAS, Delta and SkyWest are parties to the Agreement;

WHEREAS, pursuant to the terms of Amendment Number Thirty-Seven to the Agreement dated effective as of August 3, 2021 ("Amendment Thirty-Seven"), contemporaneous with the Actual In-Service Date (as defined in Amendment Thirty-Seven) of each E175(G3) Aircraft (as defined in Amendment Thirty-Seven), Operator shall remove from service within the Delta Connection Program [\*\*\*] Removed CRJ-900 Aircraft (as defined in Amendment Thirty-Seven);

WHEREAS, the Parties have agreed that the first [\*\*\*] of the Removed CRJ-900 Aircraft shall immediately following such aircraft's removal pursuant to the terms of Amendment Thirty- Seven be added as Aircraft subject to the terms of the Agreement, as amended by this Amendment; and

WHEREAS, the Parties have further agreed to remove [\*\*\*] CRJ-200 aircraft from pro rate operations and add such aircraft as Aircraft under the Agreement.

NOW, THEREFORE, for and in consideration of the mutual undertakings set forth herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Delta and SkyWest, intending to be legally bound, hereby agree to amend the Agreement as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.** **Defined Terms .** All capitalized terms used but not defined herein shall have the meaning ascribed to such terms in the Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.** **Addition of [\*\*\*] Bombardier CRJ-900 Aircraft .** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Pursuant to Section 1.A.(iii) of the Agreement, immediately following the removal of the first [\*\*\*] of the Removed CRJ-900 Aircraft, each such Removed CRJ-900 Aircraft shall be added as an Aircraft under, and subject to the terms and conditions of, the Agreement, as amended by this Amendment (the "Short-Term CRJ900 (G2) Aircraft"). Operator shall make each Short-Term CRJ900 Aircraft available to be placed into service within the Delta Connection Program concurrent with the removal of such aircraft from the terms of the Agreement pursuant to Amendment Thirty Seven (each, the "Scheduled In-Service Date"). If any Short-Term CRJ900 (G2) Aircraft is not placed in service within the Delta Connection Program by its Scheduled In-Service Date (such Short-Term CRJ900 (G2) Aircraft, a " <u>Delayed In-Service Aircraft</u> "), then Operator shall pay Delta an amount of [\*\*\*]; <u>provided</u>, Operator shall have no obligation to make such payment for any delay principally attributable to any action or omission of Delta.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Notwithstanding anything in the Agreement to the contrary, the term for which each Short- Term CRJ900(G2) Aircraft shall be included as an Aircraft under the Agreement, and subject to the terms and conditions thereof, shall commence on each respective Scheduled In-Service

------

**EXECUTION VERSION**

Date and terminate upon the earlier of [\*\*\*] (each such period, a "Short-Term CRJ900(G2) Aircraft Term"). The parties acknowledge and agree that nothing in this Amendment shall affect, amend or modify the term of the Agreement, or any termination rights, with respect to any Aircraft that is not a Short-Term CRJ900(G2) Aircraft and the terms with respect to such other Aircraft shall remain as set forth in the Agreement as of the Amendment Number Thirty-Eight Effective Date. As to each Short-Term CRJ900(G2) Aircraft, from and after the respective Scheduled In-Service Date for such aircraft, Delta shall pay Operator for certain Direct Costs and Pass-Through Costs associated with each Short-Term CRJ900(G2) Aircraft as set forth in this Amendment.

[\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. [\*\*\*]. Operator shall place each Short-Term CRJ900(G2) Aircraft in the Delta Connection livery and interior standards as in effect as of the Amendment Number Thirty-Eight Effective Date including, without limitation, cabin carpets, seat belts, seat covers, curtains, seat track covers, bin strips (if applicable) and laminates (collectively, the "Interior Standards").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. Notwithstanding Section 3.A.(ii) of the Agreement, the Parties acknowledge and agree that neither the Engine Maintenance Expense nor the Aircraft Rent/Ownership Costs for each Short-Term CRJ900(G2) Aircraft shall be included as a Pass Through Cost [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. (i) The Base Rate Costs to be applied to the Short-Term CRJ900(G2) Aircraft for the entirety of their respective Short-Term CRJ900(G2) Aircraft Terms, shall be as set forth in <u>Exhibit A</u> attached hereto. Such Base Rate Costs shall not apply to any Aircraft other than the Short-Term CRJ900(G2) Aircraft. [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Delta shall have no obligation to pay Operator the Block Hour Payment contemplated in Section 3.D of the Agreement with respect to the Short-Term CRJ900(G2) Aircraft during the respective Short-Term CRJ900(G2) Aircraft Terms of such aircraft. For the avoidance of doubt, amounts related to the Block Hour Payment that Delta pays for other Aircraft (that are not the Short-Term CRJ900(G2) Aircraft) under the Agreement are already included as part of the Base Rate Costs for the Short-Term CRJ900(G2) Aircraft set forth in <u>Exhibit A</u> attached hereto. In addition, Delta shall pay Operator, or Operator shall pay Delta, as applicable, amounts related to the Performance Incentives and Penalties applicable to the CRJ-900 Aircraft fleet subject to the terms of the Agreement in accordance with, and subject to, the terms and conditions set forth in Amendment Thirty-One to the Agreement dated December 17, 2019 ("Amendment Number Thirty-One").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Notwithstanding the provisions of Article 1.D. of the Agreement, the Delta Connection Flights to be operated by the Short-Term CRJ900(G2) Aircraft shall be primarily supported by crew and maintenance bases of Operator located at airports in the western and midwestern United States. As of the Amendment Number Thirty-Eight Effective Date, such crew and maintenance bases are as follows: crew bases ([\*\*\*]), line maintenance bases ([\*\*\*]) and overnight maintenance bases ([\*\*\*]). If to a material degree, the Short-Term CRJ900(G2) Aircraft are scheduled such that the crew and maintenance bases with respect to the Short- Term CRJ900(G2) Aircraft are not located at such airports, such act or omission shall not be a breach of the Agreement; provided, however, in any such event Delta and Operator will negotiate in good faith to agree on an appropriate economic adjustment (up or down) to the

------

**EXECUTION VERSION**

Direct Costs solely to account for the actual bases and/or maintenance bases used to support the Delta Connection Flights to be operated by the Short-Term CRJ900(G2) Aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. Notwithstanding the provisions of Article 1.D. of the Agreement, if (i) Delta submits a proposed monthly schedule of Delta Connection Flights to be operated by the Short-Term CRJ900(G2) Aircraft during such month (each, a "Proposed Monthly Short-Term CRJ900(G2) Schedule") which provides for average daily scheduled utilization measured on a calendar month basis in the aggregate for the Short-Term CRJ900(G2) Aircraft fleet (taking into account scheduled maintenance) available to schedule ("Average Short-Term CRJ900(G2) Utilization") greater than an average of [\*\*\*] per Short-Term CRJ900(G2) Aircraft [\*\*\*] during the applicable month of determination (the "Maximum Short-Term CRJ900(G2) Utilization Level") and (ii) Operator, after conducting a good faith review and analysis of such Proposed Monthly Short-Term CRJ900(G2) Schedule and its crew availability for such month, determines, in good faith, that it is unable to operate the Proposed Monthly Short-Term CRJ900(G2) Schedule as provided by Delta, then, [\*\*\*] following receipt of such Proposed Monthly Short-Term CRJ900(G2) Schedule, Operator shall have the option, upon delivering to Delta written notice, to request a reduction in such scheduled block hours in order to reduce the Average Short-Term CRJ900(G2) Utilization to the Maximum Short-Term CRJ900(G2) Utilization Level or a greater utilization level as specified by Operator (an "Short-Term CRJ900(G2) Schedule Reduction Request"). If Operator does not respond within such [\*\*\*], any such non-response shall be deemed a waiver by Operator of its right to request any schedule reduction with respect to such month's Proposed Monthly Short-Term CRJ900(G2) Schedule. Upon receipt of a Short-Term CRJ900(G2) Schedule Reduction Request, Delta shall amend the Proposed Monthly Short-Term CRJ900(G2) Schedule initially delivered by Delta to Operator to reduce the Average Short-Term CRJ900(G2) Utilization reflected in such Proposed Schedule to a level no greater than the Maximum Short-Term CRJ900(G2) Utilization Level or greater level as specified by Operator and such reduction shall thereafter be reflected in the applicable final monthly schedule for the Short-Term CRJ900(G2) Aircraft (a "Schedule Reduction"). Flights cancelled due to any such Schedule Reduction shall not be taken into account for any purposes under this Agreement, including, as pertaining to performance goals or other penalties provided for in Amendment Number Thirty-One.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;G. Operator shall select the vendor(s) to perform and complete all maintenance work associated with the Short-Term CRJ900(G2) Aircraft (including the engines associated therewith and associated parts) in Operator's sole and absolute discretion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;H. Other than the last two sentences therein, the provisions of Article 3.G. of the Agreement shall not apply with respect to the operations of the Short-Term CRJ900(G2) Aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I. [\*\*\*]

**EXECUTION VERSION**

Aircraft is not placed in service within the Delta Connection Program by [\*\*\*] (such Short- Term [\*\*\*] CRJ200 Aircraft, a "Delayed CRJ-200 In-Service Aircraft"), then Operator shall pay Delta an amount of [\*\*\*]; <u>provided</u>, Operator shall have no obligation to make such payment for any delay principally attributable to any action or omission of Delta.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Notwithstanding anything in the Agreement to the contrary, the term for which each Short- Term [\*\*\*] CRJ200 Aircraft shall be included as an Aircraft under the Agreement, and subject to the terms and conditions thereof, shall commence on [\*\*\*] and terminate upon the earlier of [\*\*\*] (each such period, a "Short-Term [\*\*\*] CRJ200 Aircraft Term"). The parties acknowledge and agree that nothing in this Amendment shall affect, amend or modify the term of the Agreement, or any termination rights, with respect to any Aircraft that is not a Short-Term [\*\*\*] CRJ200 Aircraft and the terms with respect to such other Aircraft shall remain as set forth in the Agreement as of the Amendment Number Thirty-Eight Effective Date. As to each Short-Term [\*\*\*] CRJ200 Aircraft, from and after [\*\*\*], Delta shall pay Operator for certain Direct Costs and Pass-Through Costs associated with each Short-Term [\*\*\*] CRJ200 Aircraft as set forth in this Amendment.

[\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. Operator shall place each Short-Term CRJ900(G2) Aircraft in the Delta Connection livery and Interior Standards. [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. Notwithstanding Section 3.A.(ii) of the Agreement, the Parties acknowledge and agree that neither the Engine Maintenance Expense nor the Aircraft Rent/Ownership Costs for each Short-Term 2022 CRJ200 Aircraft shall be included as a Pass Through Cost, [\*\*\*].

------

**EXECUTION VERSION**

bases with respect to the Short-Term [\*\*\*] CRJ200 Aircraft are not located at such airports, such act or omission shall not be a breach of the Agreement; provided, however, in any such event Delta and Operator will negotiate in good faith to agree on an appropriate economic adjustment (up or down) to the Direct Costs solely to account for the actual bases and/or maintenance bases used to support the Delta Connection Flights to be operated by the Short- Term [\*\*\*] CRJ200 Aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. Operator shall select the vendor(s) to perform and complete all maintenance work associated with the Short-Term [\*\*\*] CRJ200 Aircraft (including the engines associated therewith and associated parts) in Operator's sole and absolute discretion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. During the Short-Term [\*\*\*] CRJ200 Aircraft Term, Delta agrees to schedule the Delta Connection Flights of the CRJ-200 Aircraft such that Operator may perform overnight maintenance on [\*\*\*] CRJ-200 Aircraft each night at [\*\*\*] or more existing maintenance bases of Operator, as mutually agreed by the parties.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. During the Short-Term [\*\*\*] CRJ200 Aircraft Term, Operator agrees to provide, [\*\*\*] CRJ- 200 aircraft as operational and maintenance spare aircraft to support the operations and maintenance of the CRJ-200 Aircraft fleet (each, a "Spare CRJ-200 Aircraft"). Each Spare CRJ-200 Aircraft will meet the Interior Livery Standards as in effect as of this Amendment Number Thirty-Eight Effective Date; provided, that if a Spare CRJ-200 Aircraft meeting the foregoing Interior Livery is not reasonably available, then Operator may use a white tail aircraft with generic interior. When operating in substitution of a CRJ-200 Aircraft, the Spare Aircraft will be deemed an Aircraft subject to the terms of this Agreement; provided, that with respect to Base Rate Costs applicable to the operation of each Spare Aircraft in substitution of any CRJ-200 Aircraft, the applicable Base Rate Costs shall be as set forth on <u>Exhibit C</u> hereto with the exclusion of the "Aircraft Month" rate.

This Amendment may be executed in any number of counterparts, including via facsimile, each of which shall be deemed an original and all of which, taken together, shall constitute one and the same instrument.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. Except as specifically stated herein, all other terms and conditions of the Agreement shall remain in full force and effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.** **Miscellaneous.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. This Amendment constitutes the entire understanding of the parties with respect to the subject matter hereof, and any other prior or contemporaneous agreements, whether written or oral, are expressly superseded hereby.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. The Amendment may be executed in any number of counterparts and by electronic signatures, each of which shall be deemed an original and all of which, taken together, shall constitute one and the same instrument.

Notwithstanding the provisions of Article 11.A of the Agreement, Delta's extension rights with respect to the term of each E175(G4) Aircraft shall be limited to up to [\*\*\*] additional [\*\*\*] terms subject to the terms and conditions set forth in this Section 2.B. Any such extension will require (i) at least [\*\*\*] prior written notice from Delta to Operator prior to the expiration of

------

the initial term or the subsequent extension term, as the case may be, of the applicable E175(G4) Aircraft and (ii) the Parties will work together in good faith to mutually agree upon the terms of an extension agreement as to the applicable E175(G4) Aircraft, including as to the Direct Costs to be applied during the applicable extension term.

In addition, Delta shall pay Operator, or Operator shall pay Delta, as applicable, amounts related to the Performance Incentives and Penalties applicable to the E170LL Aircraft (as defined in Amendment Number Thirty dated June 21, 2019) and the E175(G3) Aircraft (as defined in Amendment Number Thirty-Seven dated as of August 3, 2021 ("<u>Amendment Number Thirty- Seven</u>")), in accordance with, and subject to, the terms and conditions set forth in Amendment Thirty-One to the Agreement dated December 17, 2019 ("<u>Amendment Number Thirty-One</u>"). [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) With respect to each E175(G4) Aircraft engine serial number (ESN) set forth on <u>Exhibit A</u> attached hereto (the "<u>Delivery Date E175(G4) Engines</u>") and [\*\*\*] engines identified in <u>Exhibit E</u> attached hereto (each, a "<u>Spare E175(G4) Engine</u>", and collectively with the Delivery Date E175(G4) Engines, the "<u>E175(G4) Engines</u>"), "Engine Maintenance Expense" as defined in Section 3.A.(ii)(1) of the Agreement for the E175(G4) Engines shall be as provided in <u>Exhibit C-2</u> attached hereto; provided, in all events, such costs shall not be treated as a Pass Through Cost but shall be deemed a Base Rate Cost for purposes of the Agreement.

In the event Operator needs additional spare engines in order to maintain a sufficient number of spare engines for the Embraer Fleet Aircraft, upon written notice to Delta, Operator may include additional spare engines as EMB Spare Engines under the terms of the Agreement, with the Parties to agree upon the applicable Embraer Fleet Aircraft to associate such additional spare engines.

Subject to Delta's prior written consent, such consent not to be unreasonably withheld or delayed, Operator may remove and, if necessary, replace an E175(G4) Engine as a result of damage or destruction of such engine. In such event, <u>Exhibit A</u> or <u>Exhibit E</u> hereto shall be amended to reflect such removal and replacement, if applicable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) For avoidance of doubt, E175(G4) Aircraft, in addition to all other Aircraft within the scope of the Agreement, is a covered Aircraft for purposes of Section 3.E of the Agreement (as amended and restated in Amendment Number Thirty-One).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii)[\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii) [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ix) With respect to the monthly reconciliation provided for in Article 3.E. of the Agreement, actual block hours, actual flight hours and actual departures with respect to the EMB Fleet

------

Aircraft (as defined in <u>Exhibit C-1</u> of this Amendment (and as such term may be amended from time to time)) will be allocated in accordance with the methodology set forth on <u>Exhibit B-2</u> attached hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. Notwithstanding the provisions of Article 1.D. of the Agreement, if (i) Delta submits a proposed monthly schedule of Delta Connection Flights to be operated by the E175(G4) Aircraft during such month (each, a " <u>Proposed Monthly E175(G4) Schedule</u> ") which provides for average daily scheduled utilization measured on a calendar month basis in the aggregate for the E175(G4) Aircraft fleet (taking into account scheduled maintenance) available to schedule (" <u>Average E175(G4) Utilization</u> ") greater than an average of [\*\*\*] per E175(G4) Aircraft [\*\*\*] during the applicable month of determination (the " <u>Maximum E175(G4) Utilization Level</u> ") and (ii) Operator, after conducting a good faith review and analysis of such Proposed Monthly E175(G4) Schedule and its crew availability for such month, determines, in good faith, that it is unable to operate the Proposed Monthly E175(G4) Schedule as provided by Delta, then, within [\*\*\*] following receipt of such Proposed Monthly E175(G4) Schedule, Operator shall have the option, upon delivering to Delta written notice, to request a reduction in such scheduled block hours in order to reduce the Average E175(G4) Utilization to the Maximum E175(G4) Utilization Level or a greater utilization level as specified by Operator (an " <u>E175(G4) Schedule Reduction Request</u> "). If Operator does not respond within such [\*\*\*] period, any such non-response shall be deemed a waiver by Operator of its right to request any schedule reduction with respect to such month's Proposed Monthly E175(G4) Schedule. Upon receipt of an E175(G4) Schedule Reduction Request, Delta shall amend the Proposed Monthly E175(G4) Schedule initially delivered by Delta to Operator to reduce the Average E175(G4) Utilization reflected in such Proposed Schedule to a level no greater than the Maximum E175(G4) Utilization Level or greater level as specified by Operator and such reduction shall thereafter be reflected in the applicable final monthly schedule for the E175(G4) Aircraft (a " <u>Schedule Reduction</u> "). Flights cancelled due to any such Schedule Reduction shall not be taken into account for any purposes under this Agreement, including, as pertaining to Performance Incentive and Penalties as set forth in Amendment Number Thirty-One.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;G. Operator shall select the vendor(s) to perform and complete all maintenance work associated with the E175(G4) Aircraft (including all E175(G4) Engines and associated parts) in Operator's sole and absolute discretion; provided, however, if Delta requests Operator to change a vendor performing engine maintenance work with respect to the E175(G4) Engines and if [\*\*\*] then, Operator will cooperate with Delta with respect to such requested change in vendor for the E175(G4) Engine maintenance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;H. Other than the last two sentences therein, the provisions of Article 3.G. of the Agreement shall not apply with respect to the operations of the E175(G4) Aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I. [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;J. To compensate Operator for ownership costs prior to the Actual In-Service Date with respect to each E175(G4) Aircraft, Delta shall pay Operator the lesser of (i) $[\*\*\*], or (ii) $[\*\*\*] per E175(G4) Aircraft for the period commencing as of the Delivery Date (as defined below) of such E175(G4) Aircraft and ending on the Actual In-Service Date of such E175(G4) Aircraft, with such payment to be made as of the date of Provisioning Payment immediately following the Actual In-Service Date of the applicable E175(G4) Aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.** **Delay** 

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. For purposes of this Section 3, the following terms shall have the respective meaning set forth herein:

"<u>Delivery Date</u>" means, as to each E175(G4) Aircraft, the date such aircraft is delivered to Operator by Embraer.

"<u>EMB Excusable Delay</u>" [\*\*\*]

"<u>EMB Non-Excusable Delay</u>" [\*\*\*]

"<u>Excusable Delay Penalty Period</u>" [\*\*\*]

"<u>Non-Excusable Delay Penalty Period</u>" [\*\*\*]

"<u>Operator Caused Delay</u>" [\*\*\*]

"<u>Operator Caused Delay Penalty Period</u>" [\*\*\*]

"<u>Scheduled Delivery Date</u>" means, as to each E175(G4) Aircraft, the last day of the Scheduled Delivery Month of such aircraft as set forth on <u>Exhibit A</u> hereto.

"<u>Service Delay Penalty Period</u>" [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. <u>Delays in Actual In-Service Date</u>. Operator hereby agrees to use commercially reasonable best efforts to cause each of the E175(G4) Aircraft to be available to be placed into service within the Delta Connection Program no later than the respective Scheduled In-Service Date (as set forth in <u>Exhibit A</u> hereto). If following the Delivery Date of the respective E175(G4) Aircraft, such aircraft is not placed in service within the Delta Connection Program by such E175(G4) Aircraft's Scheduled In-Service Date (such E175(G4) Aircraft, a " <u>Delayed In-Service Aircraft</u> "), then, during each day of the Service Delay Penalty Period, Operator shall pay Delta an amount of [\*\*\*] during the Service Delay Penalty Period; <u>provided</u>, (i) Operator is obligated at such time to pay the financing charges with respect to the E175(G4) Aircraft (disregarding differences in timing as to any such payments under the respective financing documents) with respect to the Delayed In-Service Aircraft, and if not, the amount shall be increased from $[\*\*\*] to [\*\*\*] and, (ii) Operator shall have no obligation to make such payment for any delay principally attributable to any action or omission of Delta. Delta agrees to promptly place into service within the Delta Connection Program in accordance with Delta's regular scheduling procedures such Delayed In-Service Aircraft following receipt of written certification from Operator that the aircraft is readily available and fit for service within the Delta Connection Program as contemplated by this Amendment. In addition to the foregoing, if the Delayed In- Service Aircraft is not available for service within the Delta Connection Program as contemplated by this Amendment on or before the [\*\*\*] following its Scheduled Delivery Date, then, after such [\*\*\*] and continuing until Delta receives written certification described above from Operator that the aircraft is readily available to be placed into service within the Delta Connection Program as contemplated by this Amendment, Delta shall have the right, but not the obligation, to remove such Delayed In-Service Aircraft from the scope of the Agreement upon written notice to Operator. As to matters arising with respect to the delay in such Delayed In-Service Aircraft being available for scheduled service, the foregoing represents Delta's sole and exclusive remedies attributable to such matters.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. <u>Delay in Delivery Caused by an EMB Excusable Delay.</u> Operator hereby agrees to use commercially reasonable efforts to cause Embraer to deliver each E175(G4) Aircraft by no later than such E175(G4) Aircraft's Scheduled Delivery Date. If an E175(G4) Aircraft is not delivered to Operator on or before its Scheduled Delivery Date and if such delay in delivery is attributable to an EMB Excusable Delay (such E175(G4) Aircraft, an " <u>Excusable Delayed Aircraft</u> "), then Operator shall pay Delta an amount of [\*\*\*] during the Excusable Delay Penalty Period; <u>provided</u>, (i) Operator shall have no obligation to make such payment for any delay so long as the CRJ-700 or CRJ-900 Aircraft to be removed pursuant to Section 2.C. of this Amendment on the applicable Actual In-Service Date for the applicable E175(G4) Aircraft is available to be scheduled for the operation of Delta Connection flights as provided in the Agreement during such period of delay, and (ii) Delta shall be entitled to, and Operator shall pay Delta, any and all amounts paid to Operator by Embraer as a result of the EMB Excusable Delay. Unless otherwise removed from the Agreement as provided below in this Section 3.C, the Parties shall promptly determine the revised Scheduled In-Service Date following the delivery to Operator of the Excusable Delayed Aircraft. In addition to the foregoing, if the Excusable Delayed Aircraft is not delivered to Operator by Embraer on or before the [\*\*\*] following such E175(G4) Aircraft's Scheduled Delivery Date as a result of an EMB Excusable Delay, then either Party, upon written notice to the other Party delivered within [\*\*\*] following such [\*\*\*] may terminate from the scope of the Agreement such Excusable Delayed Aircraft. If either Party fails to give such notice within such [\*\*\*] period, such Party shall be deemed to have waived its right of termination set forth in the preceding sentence. As to matters arising with respect to the delay in the delivery of such Excusable Delayed Aircraft, the foregoing represents, as to each Party, such Party's sole and exclusive remedy attributable to such matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. <u>Delay in Delivery Caused by an EMB Non-Excusable Delay.</u> Operator hereby agrees to use commercially reasonable efforts to cause Embraer to deliver each E175(G4) Aircraft by no later than such E175(G4) Aircraft's Scheduled Delivery Date. If an E175(G4) Aircraft is not delivered to Operator on or before its Scheduled Delivery Date and if such delay in delivery is attributable to an EMB Non-Excusable Delay (such E175(G4) Aircraft, a "Non-Excusable Delayed Aircraft"), then Operator shall pay Delta an amount of [\*\*\*] during the Non- Excusable Delay Penalty Period; <u>provided</u>, (i) Operator shall have no obligation to make such payment for any delay principally attributable to any action or omission of Delta, (ii) Operator shall have no obligation to make such payment for any delay so long as the CRJ-700 or CRJ- 900 Aircraft to be removed pursuant to Section 2.C. of this Amendment on the applicable Actual In-Service Date for the applicable E175(G4) Aircraft is available to be scheduled for the operation of Delta Connection flights as provided in the Agreement during such period of delay, and (iii) Delta shall be entitled to, and Operator shall pay Delta, any and all amounts paid to Operator by Embraer as a result of the EMB Non-Excusable Delay. Unless otherwise removed from the Agreement as provided below in this Section 3.D, the Parties shall promptly determine the revised Scheduled In-Service Date following the delivery to Operator of the Non- Excusable Delayed Aircraft. In addition to the foregoing, if the Non-Excusable Delayed Aircraft is not delivered to Operator by Embraer on or before the 90th day following such E175(G4) Aircraft's Scheduled Delivery Date as a result of an EMB Non-Excusable Delay, then either Party, upon written notice to the other Party delivered within [\*\*\*] following such [\*\*\*] may terminate from the scope of the Agreement such Non-Excusable Delayed Aircraft. If either Party fails to give such notice within such [\*\*\*] period, such Party shall be deemed to have waived its right of termination set forth in the preceding sentence. As to matters arising with respect to the delay in the delivery of such Non-Excusable Delayed Aircraft, the foregoing represents, as to each Party, such Party's sole and exclusive remedy attributable to such matters.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. <u>Delay in Delivery Caused by an Operator Caused Delay</u>. Operator hereby agrees to use commercially reasonable efforts to cause Embraer to deliver each E175(G4) Aircraft by no later than such E175(G4) Aircraft's Scheduled Delivery Date. If an E175(G4) Aircraft is not delivered to Operator on or before its Scheduled Delivery Date and if such delay in delivery is attributable to an Operator Caused Delay (such E175(G4) Aircraft, an " <u>Operator Delayed Aircraft</u> "), then Operator shall pay Delta an amount of [\*\*\*] during the Operator Caused Delay Penalty Period. Unless otherwise removed from the Agreement as provided below in this Section 3.E, the Parties shall promptly determine the revised Scheduled In-Service Date following the delivery to Operator of the Operator Delayed Aircraft. In addition to the foregoing, if the Operator Delayed Aircraft is not delivered to Operator by Embraer on or before the [\*\*\*] following such E175(G4) Aircraft's Scheduled Delivery Date as a result of an Operator Caused Delay, then Delta shall have the right, but not the obligation, to remove such Operator Delayed Aircraft from the scope of the Agreement upon written notice to Operator. As to matters arising with respect to the delay in the delivery of such Operator Delayed Aircraft, the foregoing represents Delta's sole and exclusive remedy attributable to such matters. [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. With respect to any amounts owed to Delta pursuant to this Section 3, Delta shall be entitled to offset or recoup the full amount of any such payments from any subsequent Provisioning Payment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.** **Removal of E175(G4) Aircraft**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. In connection with the preparation and delivery of the final monthly schedule for the E175(G4) Aircraft (each such monthly schedule, the " <u>Final Monthly E175(G4) Schedule</u> "), if after delivery of such schedule by Delta to Operator, Operator informs Delta in writing that Operator cannot fully operate the Final Monthly E175(G4) Schedule for such month for any reason that is substantially within the control of Operator (including, without limitation, crew availability) and Operator requests the removal or cancellation of scheduled flights (such requested removals and cancellations, " <u>Operator Controlled Cancellations</u> ") or if Delta, after consultation with Operator, in good faith believes Operator cannot fully operate the Final Monthly E175(G4) Schedule for such month and Delta removes or cancels scheduled flights as result thereof (such removals and cancellations, " <u>Delta Cancellations</u> "), then, Delta shall have the right to remove from the terms of the Agreement (as modified by this Amendment) for the applicable month(s) at issue (or, at Delta's sole election, on a permanent basis), [\*\*\*]. Delta shall provide written notice of such removal (temporary or permanent) within [\*\*\*] after receipt of the written notice of Operator Controlled Cancellations with respect to Operator Controlled Cancellations or, with respect to Delta Cancellations, within [\*\*\*] after delivery of the Final Monthly Schedule, whichever is applicable. With respect to any E175(G4) Removed Aircraft, Delta [\*\*\*]. In determining the number of E175(G4) Aircraft that may be removed, fractions will be rounded up or down to the nearest whole number with a number [\*\*\*] being rounded down to the nearest whole number. For the avoidance of doubt, (i) with respect to Operator Controlled Cancellations and Delta Cancellations associated with any E175(G4) Aircraft that is not removed, temporarily or permanently, from the terms of the Agreement pursuant to this Section 4.A, all such cancellations shall be considered non-completed flights for purposes of the calculation of any Performance Incentives and Penalties as provided in Amendment Number Thirty-One and (ii) Schedule Reduction Requests shall not be deemed Operator Controlled Cancellations or Delta Cancellations.

In preparing the Final Monthly E175(G4) Schedule, such schedule shall take into account scheduled maintenance for the E175(G4) Aircraft and, if applicable, the repair time for damaged E175(G4) Aircraft and accordingly, such aircraft shall not be available for scheduling during the maintenance or repair period, as applicable. For avoidance of doubt, the terms of this Section 4 shall not permit the removal (temporary or permanent) of any E175(G4) Aircraft from the terms of this Agreement as a result of scheduled maintenance and repair time; provided, however, notwithstanding the foregoing, if Operator is unable to

------

operate any of the E175(G4) Aircraft, or any of the Delta Connection Flights, due to an E175(G4) Aircraft being damaged and such damage was due to an event that was substantially within the control of, or caused by, some action or inaction of Operator, Delta shall not be obligated to pay Operator any Direct Costs, or any other amounts, in connection with such non-operated E175(G4) Aircraft and Delta Connection Flights during the period that Operator is unable to operate such damaged E175(G3) Aircraft or the Delta Connection Flights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. If [\*\*\*] or more E175(G4) Aircraft are removed on a temporary basis from the Agreement for [\*\*\*] over any [\*\*\*] rolling period, then either Delta or Operator shall, upon [\*\*\*] prior written notice to the other Party, have the right to remove on a permanent basis from the terms of the Agreement the number of E175(G4) Aircraft that have been so removed for such [\*\*\*] period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. If [\*\*\*] or more E175(G4) Aircraft are permanently removed from the terms of this Agreement as provided in this Section 4, then, Delta may, upon [\*\*\*] prior written notice to Operator, have the right to remove all, but not less than all, remaining E175(G4) Aircraft from the terms of the Agreement. If [\*\*\*] or more E175(G4) Aircraft are permanently removed from the terms of this Agreement as provided in this Section 4, then, Operator may, upon [\*\*\*] prior written notice to Delta, have the right to remove all, but not less than all, remaining E175(G4) Aircraft from the terms of the Agreement. If either Party exercises its right to remove the remaining E175(G4) Aircraft from the terms of the Agreement as provided in this Section 4.C, the Parties shall determine a mutually agreed upon wind-down schedule with respect to the remaining E175(G4) Aircraft, provided in no event shall such wind-down schedule be longer than [\*\*\*] after delivery of the election notice required by this Section 4.C.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. If [\*\*\*] or more E175(G4) Aircraft are, in each case, not available to be placed into service with the Delta Connection Program as contemplated by this Amendment more than [\*\*\*] after their respective Scheduled-In Service Dates and each such delay is due to an event that was substantially within the control of, or caused by, some action or inaction of Operator or an affiliate of Operator (including, as a result of a crew shortage), then, such unavailability shall be a material breach of the Agreement by Operator and Delta may exercise any and all of its rights and remedies to which it may be entitled with respect to such material breach in accordance with the Agreement. In addition to such rights and remedies, Delta shall also have the right, but not the obligation, upon written notice to Operator to remove all E175(G4) Aircraft from the terms of the Agreement. In such event, the Parties shall determine a mutually agreed upon wind-down schedule with respect to the E175(G4) Aircraft then subject to the Agreement, provided in no event shall such winddown schedule be longer than [\*\*\*] after delivery of the foregoing election notice. The foregoing termination right must be exercised within [\*\*\*] following the end of the [\*\*\*] late period of the [\*\*\*] delayed E175(G4) Aircraft. Failure by Delta to exercise such right within such [\*\*\*] period shall be deemed a waiver by Delta of its right of termination set forth in this Section 4.D.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. [\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F**.** With respect to any E175(G4) Aircraft that are temporarily removed from the Agreement pursuant to Section 4.A above, Operator shall not (i) operate or use any such E175(G4) Aircraft for itself or on behalf of any third party or (ii) lease, sublease, transfer, sell, assign or otherwise convey any interest into any such E175(G4) Aircraft to any third party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**5.** **Block Hour Rate Amendment with Respect to Events Not Substantially in the Control of Delta or Operator**. With respect to the block hour rates that are payable by Delta in connection with Aircraft or Delta Connection Flights not operated by Operator due to an event that is not substantially within the control of, or caused by, some action or inaction of either Operator or Delta (as contemplated by Article 3.E of the Agreement, as amended and restated in Amendment Thirty-One and further amended in Amendment Forty-Three to the Agreement dated May 9, 2023 ("Amendment Forty-Three")), effective

------

[\*\*\*], all block hour rates contained in <u>Exhibit D</u> of Amendment Thirty-One (as amended by Amendment Forty-Three) shall be deleted in their entirety and replaced with the following rates:

[\*\*\*]

[\*\*\*]. With respect to the monthly reconciliation provided for in Article 3.E, cancellations involving the EMB Fleet (as defined in <u>Exhibit C-1</u> of this Amendment (and as such term may be amended from time to time)) will be allocated in a manner consistent with the allocation of actual block hours of the EMB Fleet for the applicable month of determination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**6.** **Minimum Utilization – E175(G4) Aircraft**. The Parties agree that as to the operation of the E175(G4) Aircraft, the minimum utilization requirements set forth in Article 3.A(i) of the Agreement, as amended by Amendment Number Three to the Agreement dated July 1, 2009 shall not apply with respect to the operation of the E175(G4) Aircraft and the operation of the E175(G4) Aircraft shall not be taken into account for purposes thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**7.** **High Altitude Conversion**. Operator, [\*\*\*], will convert [\*\*\*] of the Aircraft in the EMB Fleet Aircraft into the high altitude configuration for operation into and out of [\*\*\*] (each, a "<u>HA EMB Aircraft</u>," and collectively, the "<u>HA EMB Aircraft</u>"). Operator and Delta will mutually agree on the EMB Fleet Aircraft to be so converted into the HA EMB Aircraft, each acting reasonably. Operator shall use commercially reasonable efforts to complete such conversion of all the HA EMB Aircraft [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**8.** **Miscellaneous**<u>.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. This Amendment constitutes the entire understanding of the Parties with respect to the subject matter hereof, and any other prior or contemporaneous agreements, whether written or oral, are expressly superseded hereby.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. The Amendment may be executed in any number of counterparts, including via facsimile, each of which shall be deemed an original and all of which, taken together, shall constitute one and the same instrument.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. Except as specifically stated herein, all other terms and conditions of the Agreement shall remain in full force and effect. In the event of any conflict between the terms of this Amendment and the Agreement, the terms of this Amendment shall prevail.

**E175(G4) Aircraft Configuration (ERJ 170-200LR)**

&nbsp;&nbsp;&nbsp;&nbsp;**1.** **STANDARD AIRCRAFT** 

The EMBRAER E175(G4) Aircraft (certification designation ERJ 170-200 LR) shall be manufactured according to the Technical Description which although not attached hereto, is incorporated herein by reference, and (ii) the characteristics described in the items below.

&nbsp;&nbsp;&nbsp;&nbsp;**2.** **OPTIONAL EQUIPMENT:** 

[\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;**3.** **FINISHING** 

The E175(G4) Aircraft will be delivered to Operator as follows:

&nbsp;&nbsp;&nbsp;&nbsp;**3.1** **EXTERIOR FINISHING:** 

The fuselage of the E175(G4) Aircraft shall be painted according to the Delta Connection color and paint scheme provided by Delta to Operator, which shall be supplied to Embraer by Operator on or before [\*\*\*] prior to the first E175(G4) Aircraft Contractual Delivery Date. The wings and the horizontal stabilizer shall be supplied in the standard colors, i.e., grey BAC707.

The choices of colour and paint scheme made by Operator, at the direction of Delta, shall apply to all E175(G4) Aircraft, unless Operator, at the direction of Delta, provides written notice of a new colour and paint scheme not less than [\*\*\*] prior to the relevant E175(G4) Aircraft Contractual Delivery Date.

&nbsp;&nbsp;&nbsp;&nbsp;**3.2** **INTERIOR FINISHING:** 

Operator shall inform Embraer during the customer check list definition ("CCL"), to be held no later than [\*\*\*] prior to the applicable E175(G4) Aircraft Contractual Delivery Date (or such later date as Embraer shall agree), of its choice, at the direction of Delta, of materials and colours of all and any item of interior finishing such as seat covers, carpet, floor lining on galley areas, side walls and overhead lining, galley lining and curtain, from the choices offered by and available at Embraer. In case Operator opts, at the direction of Delta, to use different materials and/or patterns, Embraer will submit to Operator, who shall provide the same to Delta, a Proposal of Major Change ("PMC") describing the impacts of such option, if any. Should Operator, at the direction of Delta, not approve such PMC, the interior shall be built according to the choices offered by and available at Embraer.

Once defined, for the applicable CCL the choices of interior finishing made by Operator, at the direction of Delta, shall apply to all applicable E175(G4) Aircraft. If Operator requires, at the direction of Delta, an interior finishing for any Aircraft that is different from the original one informed to Embraer, Operator shall present a written request to Embraer not less than [\*\*\*] prior to the relevant E175(G4) Aircraft Contractual Delivery Date and Embraer will submit the relevant quotation to the approval of Operator within [\*\*\*] from the date such request is received by Embraer. Should Operator, at the direction of Delta, not approve the quotation, the interior of relevant Aircraft shall be built according to the original choice of Operator.

------

&nbsp;&nbsp;&nbsp;&nbsp;**3.3** **BUYER FURNISHED EQUIPMENT (BFE) AND BUYER INSTALLED EQUIPMENT (BIE):** 

Operator, at the direction of Delta, may choose to have carpets, tapestries, seat covers and curtain fabrics supplied to Embraer for installation in the Aircraft as BFE. Materials shall conform to the required standards and comply with all applicable regulations and airworthiness requirements. Delays in the delivery of BFE equipment or quality restrictions that prevent the installation thereof in the time frame required by the E175(G4) Aircraft manufacturing process shall entitle Embraer to either delay the delivery of the E175(G4) Aircraft for a period related to the delay of the BFE or present the E175(G4) Aircraft to Operator without such BFE, in which case Operator shall not be entitled to refuse acceptance of the E175(G4) Aircraft.

All BFE equipment shall be delivered in DDP conditions (INCOTERMS 2010) to C&D Zodiac – 14 Centerpointe Drive, La Palma, CA 90623, USA, or to another place to be timely informed by Embraer.

Galley inserts (such as coffee makers, water boilers, ovens), trolleys and standard units and medical kits, defibrillators and wheelchairs, as well as any other equipment classified as medical or pharmaceutical product, shall be acquired by Operator and installed on the E175(G4) Aircraft by Operator after delivery thereof as BIE.

Notwithstanding the above, Operator shall deliver in DDP conditions (INCOTERMS 2010) to C&D Zodiac one full set of galley inserts (such as coffee makers, water boilers, ovens) for installation solely in the first Aircraft as BFE.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Fares, Rules and Seat Inventory</u>. United shall establish and publish all fares and related tariff rules for all seats on the Covered Aircraft. Contractor shall not publish any fares, tariffs, or related information for the Covered Aircraft. In addition, United shall have complete control over all seat inventory and inventory and revenue management decisions for the Covered Aircraft, including overbooking levels, discount seat levels and allocation of seats among various fare buckets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)<u>Flight Schedules</u>. United shall, in its sole discretion, establish and publish all schedules for the Covered Aircraft (such scheduled flights, together with Charter Flights, referred to herein as "<u>Scheduled Flights</u>"), including determining the city-pairs served, frequencies, utilization and timing of scheduled arrivals and departures, and shall, in its sole discretion, make all determinations regarding the establishment and scheduling of any flights other than Scheduled Flights; *provided* that such schedules shall be subject to Reasonable Operating Constraints and Conditions and the provisions of this <u>Section 2.1</u>; and *provided further* that Contractor shall operate all Charter Flights in accordance with the provisions set forth on <u>Exhibit P</u>; and *provided further* that Scheduled Flights may include flights from a maintenance base to any Applicable Airport or from one Hub Airport to another Hub Airport. United shall also be entitled, in its sole discretion and at any time prior to takeoff, to direct Contractor to delay or cancel a Scheduled Flight, including without limitation for delays and cancellations that are ATC or weather related, and Contractor shall take all necessary action to give effect to any such direction; *provided* that, if United, following delivery of a Final Monthly Schedule, directs the cancellation of a number of flights [\*\*\*]. Contractor shall be entitled to make such maintenance, ferry and repositioning flights as may be required to facilitate the proper maintenance of the Covered Aircraft or to accommodate the Scheduled Flights. At least [\*\*\*] calendar days prior to the first day of each month to which a proposed Final Monthly Schedule relates, United shall present a planned flight schedule for such month, together with a proposed Final Monthly Schedule for the following two (2) months. United shall review and consider any changes to the planned flight schedule for the Covered Aircraft, including the proposed Final Monthly Schedule, suggested by Contractor. Not later than [\*\*\*] calendar days prior to the beginning of the calendar month to which a proposed Final Monthly Schedule relates, United will deliver to Contractor the Final Monthly Schedule. Following such delivery of the Final Monthly Schedule, however, United may make such adjustments to the Final Monthly Schedule as it deems appropriate (subject to Reasonable Operating Constraints and Conditions). If such adjustment is attributable to other than a request from either Contractor or an affiliate of Contractor, then the parties shall, at Contractor's election and in advance of any change to the affected Scheduled Flight as set forth in the Final Monthly Schedule, use commercially reasonable efforts to agree upon any material actual incremental labor costs, if any, that will be incurred by Contractor attributable to such change in schedule, each party acting reasonably, and such agreed-upon increased labor costs, if any, shall be paid in accordance with Section <u>3.6(c)(ii)</u>; *provided*, that an adjustment attributable to any reason affecting the availability of aircraft, as such availability is reasonably determined by United, shall be deemed to be an adjustment attributable to a request from Contractor or any affiliate of Contractor, regardless of whether Contractor or any affiliate of Contractor actually makes such a request.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>Spare Aircraft</u>. Notwithstanding anything to the contrary contained in this <u>Section 2.1</u> but subject to the provisions below in this <u>Section 2.1(d)</u>, Contractor shall maintain

------

***Execution Version***

the number of spare regional jet aircraft equal to the quotient obtained by dividing (x) the sum of the number of Covered Aircraft and the number of all covered aircraft under each other capacity purchase or similar agreement between or among United and Contractor (excluding EMB 120 aircraft), by (y) [\*\*\*], and rounding the quotient to the nearest whole number. The spare regional jet aircraft shall be constituted from either Covered Aircraft (the "<u>Spare Aircraft</u>") or other covered aircraft (excluding EMB 120 aircraft) under other capacity purchase or similar agreements between United and Contractor (the "<u>Other Spare Aircraft</u>"), or both, in a proportion determined by United. After United has so instructed Contractor as to such proportion (which is not expected to occur until the adoption of an appropriate amendment to the 2003 Agreement in order to give effect to provisions equivalent to this <u>Section 2.1(d)</u>), Contractor shall select the specific hulls that shall constitute the Spare Aircraft and Other Spare Aircraft; *provided* that if Contractor has not received instruction or direction from United pursuant to the foregoing sentences of this <u>Section 2.1(d)</u> prior to the delivery of the [\*\*\*] Covered Aircraft listed on <u>Schedule 1</u>, then such [\*\*\*] Covered Aircraft shall be a Spare Aircraft, and if Contractor has not received instruction or direction from United pursuant to the foregoing sentences of this <u>Section 2.1(d)</u> prior to the delivery of the [\*\*\*] Covered Aircraft listed on <u>Schedule 1</u>, then such [\*\*\*] Covered Aircraft shall be a Spare Aircraft. Contractor shall be entitled to use the Spare Aircraft in Contractor's reasonable discretion to replace another regional jet aircraft in the operation of a flight scheduled in the Final Monthly Schedule. In addition, subject to applicable Reasonable Operating Constraints and Conditions, Contractor shall use such Spare Aircraft to operate flights as directed by United (unless such Spare Aircraft was, prior to such direction by United, already scheduled as contemplated by the immediately preceding sentence), including flights originally scheduled to be operated by United or other United service providers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)<u>Rest Over-Night (RON) Aircraft</u>. With regard to RON maintenance, the Covered Aircraft will be scheduled to operate within Contractor's existing maintenance facilities framework as of the Effective Date (consisting of COS, FAT, MKE, ORD, PSP, SLC and TUS), unless both parties mutually agree otherwise.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.2 <u>Revenues</u>.

Contractor acknowledges and agrees that all revenues resulting from the sale and issuance of passenger tickets associated with the operation of the Covered Aircraft and all other sources of revenue associated with the operation of the Covered Aircraft or the provision of Regional Airline Services, in each case following the Effective Date and during the Term, including without limitation revenues relating to Charter Flights, the transportation of cargo or mail, the sale of food, beverages and onboard entertainment, checked baggage fees, duty-free services, exterior and interior advertising and guaranteed or incentive payments from airport or governmental authorities, civic associations or other third parties in connection with scheduling flights to such airport or locality, are the sole property of and shall be retained by United (or, if received by Contractor or Parent, shall be promptly remitted to United, free and clear of claims of any third party arising by, through or under Contractor or Parent or their affiliates). The parties agree that the foregoing revenue shall not include manufacturer rebates or other incentives attributable to the acquisition or operation by Contractor of the Covered Aircraft received by Contractor from any manufacturer except to the extent provided in <u>Section 8.4(b)</u> or <u>Section 10.5</u>. Contractor agrees that it shall reasonably cooperate with United so as to permit

------

***Execution Version***

United to receive all revenues of the type described above (and United agrees to promptly reimburse Contractor for the reasonable out-of-pocket expenses incurred by Contractor in connection therewith). Contractor's and its affiliates' obligations to remit funds under this <u>Section 2.2</u> shall only apply to the extent that Contractor or any such affiliate actually receives such revenues.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.3 <u>Pass Travel</u>.

All pass travel and other non-revenue travel on any Scheduled Flight shall be administered in accordance with <u>Exhibit C</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.4 <u>Certain Events</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)If the Pre-Tax Margin of UCH, (i) as measured in the aggregate over [\*\*\*] consecutive fiscal quarters, is equal to or less than negative [\*\*\*], or (ii) is equal to or less than negative [\*\*\*] over [\*\*\*] consecutive fiscal quarters, then, in either case, United shall have the right, in its sole discretion, to terminate this Agreement with respect to some or all of the Covered Aircraft as provided in this <u>Section 2.4</u> by written notice to Contractor within [\*\*\*] days following the end of such [\*\*\*] consecutive quarter (any such notice, a "<u>Distress Notice</u>") (which Distress Notice shall specify the number of aircraft to be terminated and a Termination Date not earlier than [\*\*\*] days following the date of such Distress Notice), following which the provisions of <u>Section 8.3(b)</u> shall apply; *provided* that if United elects to terminate this Agreement with respect to Covered Aircraft pursuant to this <u>Section 2.4</u>, then (i) the provisions of <u>Section 10.1</u> shall apply, except that United must exercise the Call Option with respect to such Covered Aircraft that are owned or leased by Contractor (other than any such aircraft leased from United) (subject to the immediately following sentence) (such aircraft, the "<u>Call Option Removed Aircraft</u>"), and (ii) United shall pay Contractor the wind-down expenses as provided in <u>Section 2.4(d)</u> below. Notwithstanding the foregoing, Contractor shall have the right to retain, and United shall then not have the right or obligation to acquire, any or all such Call Option Removed Aircraft, upon written notice by Contractor to United exercising such right to retain within [\*\*\*] days of Contractor's receipt of the Distress Notice. For the avoidance of doubt, United shall pay Contractor the expenses as provided in <u>Section 2.4(d)</u> below whether or not Contractor exercises its right to retain any or all such Call Option Removed Aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)At any time and from time to time, United shall have the right, in its sole discretion, to terminate this Agreement with respect to some or all of the Covered Aircraft as provided in this <u>Section 2.4</u> by delivering a notice (a "<u>2.4(b) Notice</u>") to Contractor (which 2.4(b) Notice shall specify the number of aircraft to be terminated and a Termination Date not earlier than [\*\*\*] days following the date of such 2.4(b) Notice), following which the provisions of <u>Section 8.3(b)</u> shall apply; *provided* that if United elects to terminate this Agreement with respect to some or all of the Covered Aircraft pursuant to this <u>Section 2.4</u>, then (i) the provisions of <u>Section 10.1</u> shall apply, except that United must exercise the [\*\*\*], and (ii) United shall pay Contractor the expenses as provided in <u>Section 2.4(e)</u> below. Notwithstanding the foregoing, Contractor shall have the right to retain, and United shall then not have the right or obligation to acquire, any or all such Call Option Removed Aircraft, upon written notice by Contractor to United exercising such right to retain within [\*\*\*] days of Contractor's receipt of the 2.4(b)

------

***Execution Version***

Notice. For the avoidance of doubt, United shall pay Contractor the expenses provided in <u>Section 2.4(e)</u> below whether or not Contractor exercises its right to retain any or all such Call Option Removed Aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)United's right to terminate all or part of the Covered Aircraft as provided in <u>Section 2.4</u> (each aircraft so terminated, a "<u>Removed Covered Aircraft</u>") shall be subject to the following conditions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) If United terminates this Agreement as to some or all Covered Aircraft pursuant to <u>Section 2.4(a)</u>, then, United may terminate this Agreement as to Covered Aircraft only in the same proportion as United terminates the respective codeshare arrangement(s) with another domestic United Express regional aircraft operator (any such operator, an " <u>Other Large Gauge Operator</u> ") for the respective operation of Large Gauge Regional Aircraft, determined collectively. For purposes of determining proportionality pursuant to the preceding sentence in this <u>clause (i)</u>, the termination of a codeshare arrangement with an Other Large Gauge Operator with respect to an aircraft shall count if such termination occurs within [\*\*\*] of the termination of a Covered Aircraft (other than such a termination due to the natural expiration of the respective agreement as to such aircraft under the terms of the respective codeshare arrangement with the Other Large Gauge Operator). For example, if (x) [\*\*\*] Large Gauge Regional Aircraft (including the Covered Aircraft) are operated domestically for United, and Contractor operates [\*\*\*] Covered Aircraft and (y) United desires to terminate the domestic operation of [\*\*\*] Large Gauge Regional Aircraft, then United shall terminate [\*\*\*] Covered Aircraft [\*\*\*] and [\*\*\*] Large Gauge Regional Aircraft operated by Other Large Gauge Operators; also, the [\*\*\*] aircraft shall be removed in a proportional manner, such that the number of Covered Aircraft removed at any time during the process is never more than two more or two less than the applicable percentage [\*\*\*] of total aircraft removed at such time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) If United terminates this Agreement as to some, but not all of the Covered Aircraft pursuant to <u>Section 2.4(a)</u> or <u>(b)</u>, the aggregate number of Covered Aircraft withdrawn pursuant to <u>Section 2.4(a)</u> or <u>(b)</u>, as applicable, shall in no event reduce the Covered Aircraft operated by Contractor to less than [\*\*\*] Covered Aircraft (excluding, for this purpose, Covered Aircraft subject to a Wind-Down Schedule); *provided*, that if the Covered Aircraft operated by Contractor hereunder is [\*\*\*] aircraft, then all [\*\*\*] such aircraft shall be operated from a single Hub Airport.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) Removed Covered Aircraft removed from this Agreement pursuant to <u>Section 2.4(a)</u> and the corresponding Large Gauge Regional Aircraft removed from the operations of Other Large Gauge Operators in connection therewith shall, in each case, not be further used by United (or any affiliate of United) for domestic aircraft operations during the Term; *provided*, that if United desires to return into service prior to the end of the Term some or all of such Removed Covered Aircraft and the other Large Gauge Regional Aircraft removed from the

------

***Execution Version***

operations of Other Large Gauge Operators in connection therewith, then United agrees that it will not return any such aircraft to Other Large Gauge Operators unless Removed Covered Aircraft equaling a proportionate number of all such aircraft returning into service are returned to Contractor pursuant to this Agreement on the same economic terms as applicable at the time of the removal of such Covered Aircraft from this Agreement, such proportion to be measured as described above in <u>clause (i)</u>, and such return to be implemented in the proportional manner described above in <u>clause (i)</u>; *provided, further,* that if any such Removed Covered Aircraft shall have been sold or leased by United (or is under contract to be sold or leased at the time of application of this <u>clause (iii)</u>), then United shall not be required to return such aircraft to service hereunder and the proportions described above shall be adjusted to remove such aircraft from such measurement; and *provided, further*, that any such Removed Covered Aircraft being returned to operation as a Covered Aircraft hereunder shall be returned within [\*\*\*] of the return to service of any other aircraft operated by Other Large Gauge Operators; and *provided, further,* United shall not discriminate against Contractor with respect to the sale or lease of such Removed Covered Aircraft, on the one hand, and Other Large Gauge Regional Aircraft operated by Other Large Gauge Operations, on the other hand (it being understood that the sale of a disproportionate share of such Removed Covered Aircraft or Other Large Gauge Regional Aircraft at the request of a buyer shall not constitute discrimination on United's part).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) United may terminate this Agreement as to a Covered Aircraft under <u>Article 2.4(a)</u> or <u>(b)</u> only upon satisfaction of the terms of <u>Section 10.1</u>; *provided,* that this <u>Section 2.4(c)(iv)</u> shall not apply if Contractor does not comply with its obligations arising under <u>Section 10.1</u>, which failure to comply has not been cured within [\*\*\*] days following written notice of such failure from United.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) At the time of the exercise by United of any of its rights hereunder, United shall provide to Contractor a certificate signed by an officer of United certifying United's compliance with the terms of <u>Sections 2.4(c)(i)</u>. Thereafter until the earlier of (x) the end of the Term or (y) the sale or sublease, or return to a lessor, in each case by United, or the return to service under this Agreement, of all of such Removed Covered Aircraft, and upon the written request of Contractor (but no more than once in any calendar year), United shall provide to Contractor a certificate signed by an officer of United certifying United's compliance with the terms of <u>Section 2.4(c)(iii)</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)In connection with any termination of Covered Aircraft pursuant to <u>Section 2.4(a)</u>, United will be responsible for [\*\*\*], in each case incurred by Contractor as a direct result of the removal of any Removed Covered Aircraft (using commercially reasonable efforts to mitigate such costs) and reasonably documented in connection with such termination of such Covered Aircraft.

***Execution Version***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)In connection with any termination of Covered Aircraft pursuant to <u>Section 2.4(b)</u>, United will pay Contractor an amount in respect of each such Covered Aircraft equal to the product of:

[\*\*\*].

**ARTICLE III** 

**CONTRACTOR COMPENSATION**

For and in consideration of the services to be provided by Contractor pursuant to the terms and conditions of this Agreement, and subject to the terms and conditions set forth herein,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)United shall be responsible for (a) paying to Contractor Compensation for Carrier Controlled Costs and the Incentive Markup Payments, if any, (b) reimbursing Contractor for the Pass- Through Costs, and (c) incurring directly the expenses described in <u>Section 3.4(a)</u>, and United shall not be responsible for any other costs or expenses incurred by Contractor hereunder, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)Contractor shall be responsible for incurring directly the expenses described in <u>Section 3.4(b)</u>, in each case as more specifically provided below in this <u>Article III</u>, such amounts to be paid and reconciled as set forth in <u>Section 3.6</u> below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.1 <u>Compensation for Carrier Controlled Costs</u>.

For and in consideration of the services to be provided by Contractor pursuant to the terms and conditions of this Agreement, United shall make payments to Contractor, subject to the terms and conditions set forth in this <u>Article III</u> and elsewhere in this Agreement, for each of the following measurements: (i) ownership rate per month in respect of each Covered Aircraft,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) completed block hours flown for Scheduled Flights, (iii) completed flight hours flown for Scheduled Flights, (iv) number of completed Scheduled Flight departures, and (v) the maintenance, crew and administrative overhead cost per month in respect of each Covered Aircraft, in each case in accordance with the rates set forth on <u>Schedule 2</u> (all such compensation associated with (ii), (iii) and (iv), collectively, the "<u>Flight Reconciled Carrier Controlled Costs</u>," and all such compensation associated with (i) and (v), collectively, "<u>Ownership Rate</u>", and, such Ownership Rate and Flight Reconciled Carrier Controlled Costs, collectively, the "<u>Compensation for Carrier Controlled Costs</u>"). Compensation for Carrier Controlled Costs shall be paid as provided in <u>Section 3.6</u> below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.2 <u>Incentive Compensation</u>.

United and Contractor have developed a monthly incentive payment program (the "<u>Incentive Program</u>") under which Contractor shall earn monthly incentive markup payments calculated as a percentage of Compensation for Carrier Controlled Costs for such month, all as more fully set forth below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Under the Incentive Program, operating performance goals (the "<u>Operating Goals</u>") for Contractor's operation of Scheduled Flights shall be set with respect to the following measurements (each, an "<u>Operating Performance Measure</u>"): (i) On-Time Departure Rate, (ii) Controllable Completion Factor and (iii) Customer Satisfaction Score. Except as otherwise

------

***Execution Version***

provided in <u>Section 3.2(c)</u> for the period beginning as of the first Actual In-Service Date for any Covered Aircraft and ending December 31, 2014, each initial Operating Goal, effective through and including the next succeeding December 31, will be established on the Commencement Date and shall be reestablished for each succeeding calendar year, using the applicable predetermined methodology as set forth below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) If with respect to any Operating Performance Measure for a calendar year (or any portion thereof, as the case may be), the Domestic Mainline Operations Performance Level (measured for the prior calendar year) is greater than the [\*\*\*] (measured for the prior calendar year), then the methodology set forth below shall be used to determine the Operating Goal relating to such Operating Performance Measure for each month in such calendar year (or any portion thereof, as the case may be).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) Contractor's Operating Goal relating to On-Time Departure Rate (the " <u>On-Time Zero Operating Goal</u> ") for the upcoming period shall be equal to [\*\*\*] On-Time Departure Rate for its [\*\*\*] for the measured period, (x) adjusted [\*\*\*] percentage points, (y) further adjusted for regional differences by multiplying such number by a quotient (the " <u>Regional Adjustment Quotient</u> "), the numerator of which is the weighted average of each separate On-Time Departure Rate for such calendar year for [\*\*\*] at each Hub Airport from which Contractor operates Scheduled Flights, weighted by the number of Scheduled Flight departures from each such Hub Airport, and the denominator of which is [\*\*\*] On-Time Departure Rate for its [\*\*\*] for such calendar year and (z) further adjusted by the Seasonality Adjustment Factor, if applicable, as provided by <u>Section 3.2(a)(iii)</u> below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) Contractor's Operating Goal relating to its Controllable Completion Factor (the " <u>Controllable Completion Operating Goal</u> ") for the upcoming period shall be equal to [\*\*\*], (x) adjusted downward by [\*\*\*] and (y) further adjusted by the Seasonality Adjustment Factor, if applicable, as provided in <u>Section 3.2(a)(iii)</u> below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(C) Contractor's Operating Goal relating to Customer Satisfaction Score (the " <u>Customer Satisfaction Operating Goal</u> ") for the upcoming period shall be equal [\*\*\*], adjusted downwards by [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) If, with respect to any Operating Performance Measure for a calendar year (or any portion thereof, as the case may be), the [\*\*\*] (measured for the prior calendar year) is greater than the [\*\*\*] (measured for the prior calendar year), then the methodology set forth below shall be used to determine the Operating Goal relating to such Operating Performance Measure for each month in such calendar year (or any portion thereof, as the case may be).

***Execution Version***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) The On-Time Zero Operating Goal for the upcoming period shall be equal to the On-Time Departure Rate constituting part of the [\*\*\*] (measured for the prior year) (x) adjusted [\*\*\*] percentage points, (y) further adjusted for regional differences by multiplying such number by the Regional Adjustment Quotient and (z) further adjusted by the Seasonality Adjustment Factor, if applicable, as provided by <u>Section 3.2(a)(iii)</u> below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) The Controllable Completion Operating Goal for the upcoming period shall be equal to the Controllable Completion Factor constituting part of the [\*\*\*] (measured for the prior year), (x) adjusted downward by [\*\*\*] and (y) further adjusted by the Seasonality Adjustment Factor, if applicable, as provided in <u>Section 3.2(a)(iii)</u> below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(C) The Customer Satisfaction Operating Goal for the upcoming period shall be equal to the Customer Satisfaction Score constituting part of the [\*\*\*] (measured for the prior year), adjusted downward by [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) <u>Seasonality Adjustment</u>. As of the Commencement Date and as of the beginning of each subsequent calendar year, after the On-Time Zero Operating Goal has been calculated by the methodology outlined above but before such Operating Goal has been finalized, Contractor may adjust the On-Time Zero Operating Goal for each month in such period by applying a seasonality factor developed by Contractor and approved by United (any such factor, expressed as a percentage, a " <u>Seasonality Adjustment Factor</u> "); *provided* that the straight average of each of the resulting monthly On-Time Zero Operating Goals and the Controllable Completion Operating Goals shall equal the respective unadjusted goals as provided above; *provided further*, that the Seasonality Adjustment Factor shall in no event exceed [\*\*\*] with respect to the On-Time Zero Operating Goal or [\*\*\*] with respect to the Controllable Completion Operating Goal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Performance Levels</u>. The Operating Goals shall be used to determine four performance levels, "A," "B," "C" and "D" (each a "<u>Performance Level</u>") as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) <u>Operating Goals Establish B-Level Performance</u>. The Operating Goals shall define the minimum performance necessary to achieve at least the "B" Performance Level.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) <u>Performance Grade Widths</u>. The ranges between the lowest ends of consecutive Performance Levels set forth on <u>Schedule 4</u> (" <u>Grade Widths</u> ") shall be as set forth on <u>Schedule 4</u> hereto and will not be changed at any time during the entire Term of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) <u>Setting All Performance Levels</u>. Immediately following the periodic establishment of the Operating Goals, constituting the low end of "B" Performance Level, and using the Grade Widths, the level of performance corresponding to each of the "A," "B," "C" and "D" Performance Levels will be

For example, if the Controllable Completion Operating Goal for a measurement period is determined to be [\*\*\*], such number shall be the lowest end of the "B" Performance Level. Applying the methodology, in the Grade Width table referenced above, the bottom of the "A" Performance Level would be [\*\*\*]. Furthermore, the bottom of the "C" Performance Level would be [\*\*\*]. Based on these numbers and the Grade Widths, and before application of any Seasonality Adjustment Factors, the range of the Performance Levels would be as follows:

"A" Performance Level=[\*\*\*]

"B" Performance Level=[\*\*\*]

"C" Performance Level=[\*\*\*]

"D" Performance Level=[\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)For each calendar month during the Term during which Scheduled Flights shall have been flown, Contractor's level of performance under this Agreement with respect to the Operating Goals ("<u>Contractor's Performance</u>") shall be measured against the Performance Levels, and a "Contractor Grade" shall be determined with respect to each Operating Goal; *provided* that no Incentive Markup Payments shall be payable with respect to any Covered Aircraft prior to its Actual In-Service Date; *provided further* that, for the period beginning as of the first Actual In-Service Date for any Covered Aircraft and ending December 31, 2014, Contractor's Performance shall be deemed to be no worse [\*\*\*] level performance for all purposes of this Agreement.

Following the determination of each Contractor Grade for each month, any applicable markup percentage shall be determined pursuant to <u>Schedule 4</u>, and such markup percentage shall be applied to the Compensation for Carrier Controlled Costs for the applicable month as part of the reconciliation process set forth in <u>Section 3.6</u> (any payment owed to Contractor by United associated with such a markup, an "<u>Incentive Markup Payment</u>").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.3 <u>Certain Adjustments of Compensation for Carrier Controlled Costs</u>.

Any audit conducted pursuant to this <u>Section 3.5</u> shall be paid for by United, unless pursuant to such audit it is determined that Contractor owes United in excess of [\*\*\*] ("<u>Excess Audit Amount</u>"), in which case Contractor shall pay to United the reasonable costs and expenses incurred by United in connection with such audit; *provided*, that if United

Contractor shall acquire at Contractor's cost and expense any software associated with the ARINC communications addressing and reporting system and ACARS based equipment, in each case, reasonably selected by United to provide such operational information as United shall direct. Any upgrade of equipment or hardware associated with ARINC or ACARS occurring after the initial acquisition of the Covered Aircraft and at United's direction shall be at United's cost and expense.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Contractor shall provide United with timely communication regarding the status of all flights.

At either party's request, Contractor and United will meet to discuss and review Contractor's customer service procedures and policies and its employees' conduct, appearance and training standards and policies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h)Contractor acknowledges that United may implement programs to evaluate the delivery of customer service and adherence to customer service standards established by United and Contractor hereby agrees to fully comply with all aspects of any such programs; *provided*, that United agrees to pay mutually agreed material incremental costs, if any, resulting from such implementation. Contractor acknowledges that pursuant to such programs United may directly observe customer service delivery and provide Contractor with findings and corrective actions. Contractor acknowledges that Contractor's required compliance with such programs shall include without limitation (i) Contractor's provision of certain data to United, as requested, for customer service quality evaluations and assessments by United and (ii) Contractor's compliance with corrective actions required by United.

Contractor agrees to accept any and all DOT-issued complaints as an air carrier for any reason or cause. Contractor agrees that any such complaint, regardless of whether the basis for such complaint is within Contractor's control, shall be accepted as a Contractor complaint for DOT purposes. For the avoidance of doubt, no complaint recorded on a Contractor flight, inclusive of station origin and destination, will count against United's DOT complaint rate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.5 <u>DOD Approval</u>.

Contractor must maintain Department of Defense air carrier approval per 32 CFR Part 861 and agrees to notify United immediately if changes to such status occur.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) due to circumstances relating to Contractor's IT systems, maintenance, flight crew or movement of overnight aircraft to or from remote hangar locations or (ii) required to accommodate United's flight schedule. For so long as Contractor provides ground handling services under a separate ground handling contract at SFO, DEN or LAX, United agrees to provide aircraft movement (towing teams) at each such airport for movement of Covered Aircraft other than for circumstances relating to Contractor's IT systems, maintenance, flight crew or movement of overnight aircraft to or from remote hangar locations. For the avoidance of doubt, if Contractor no longer provides ground handling services at SFO, DEN or LAX, then Contractor shall be obligated, and United shall not be obligated, to provide aircraft movement (towing teams) at each such airport due to circumstances relating to Contractor's IT systems, maintenance, flight crew or movement of overnight aircraft to or from remote hangar locations or as otherwise required to accommodate United's flight schedule; *provided* that, in such case, United and Contractor agree to meet and discuss aircraft movements in excess of the number that would be expected based on United's flight schedule in circumstances where no gating or facility layout constraints exist, and United agrees to make mutually agreed payments to Contractor for such excess towing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.7 <u>Incidents or Accidents</u>.

Contractor shall promptly notify United of all irregularities involving a Scheduled Flight or Covered Aircraft operated by Contractor, including, without limitation, aircraft accidents and incidents, which result in any damage to persons and/or property or may otherwise result in a complaint or claim by passengers or an investigation by a governmental agency or authority. Contractor shall furnish to United as much detail as practicable concerning such irregularities and shall cooperate with United at Contractor's own expense in any appropriate investigation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.8 <u>Emergency Response</u>.

Contractor shall adopt United's Emergency Response Plan for aircraft accidents or incidents and shall be responsible for United's direct costs resulting from Contractor's participation in such plan. In the event of an accident or incident involving a Covered Aircraft or Scheduled Flight, United will have the right, but not the obligation, exercised in United's sole discretion, to manage in coordination with Contractor the emergency response efforts on behalf of Contractor with full cooperation from Contractor; *provided* that, in all events, Contractor shall manage in coordination with United the initial response and on scene investigation.

In the event of a reasonable safety concern, United shall have the right, at its own cost, to inspect, review, and observe Contractor's operations of Scheduled Flights. Notwithstanding the conduct or absence of any such review, Contractor is and shall remain solely responsible for the safe operation of its aircraft and the safe provision of Regional Airline Services, including all Scheduled Flights, in each case in accordance with the standards, agreements, representations

Contractor hereby covenants (i) to comply and maintain compliance with the requirements of such audits within the timeframe required by IATA and (ii) maintain its membership in the IOSA registry; *provided* that United shall pay its pro-rata portion of all audit costs incurred by Contractor with respect to the foregoing, such proration to be determined by the proportion of (x) the number of available seat miles attributable to all Scheduled Flights during the prior twelve (12) month period to (y) the sum of the number of available seat miles attributable to Contractor's provision of regional airline services to all mainline carriers and the number of available seat miles attributable to Contractor's own pro-rate flying operations during such twelve (12) month period. Any failure to maintain compliance shall immediately be brought to United's attention along with corrective actions taken or a corrective action plan. Although the IOSA is to be completed biennially, United in its sole discretion may require, and Contractor shall comply with, additional safety review audits, at United's cost and expense. Nothing in <u>Exhibit N</u>, this <u>Section 4.9</u>, or otherwise in this Agreement is intended or shall be interpreted to make United responsible for such safety matters.

Each Contractor Terminal Facility that is not a Passenger-Related Terminal Facility used for the provision of Contractor Services, and each other facility used by Contractor for the provision of Contractor Services, may be used by Contractor in connection with other flights or for other purposes; *provided*, that Contractor shall use such facilities for the provision of Contractor Services in priority to any such other use, and any such other use of such facilities shall be subordinate to Contractor's use for the provision of Contractor Services.

As referenced herein, "United rules" shall be such rules, regulations and policies as have been provided by United to Contractor prior to the Effective Date, as such rules may be updated by United from time to time; *provided* that such United rules, as updated, shall be applicable to all United Express Operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) The term " <u>Hazardous Materials</u> " means any substances, whether solid, liquid or gaseous, which are listed and/or regulated as hazardous, toxic, or similar terminology under any Environmental Laws or which otherwise cause or pose threat or hazard to human health, safety or the environment, including, but not limited to, petroleum and petroleum products.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) <u>Contractor Obligations</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Contractor shall conduct its operations in a prudent manner, taking commercially reasonable preventative measures to avoid liabilities under any Environmental Laws or harm to human health or the environment, including, without limitation, measures to prevent unpermitted releases of Hazardous Materials to the environment, adverse environmental impacts to on-site or off-site properties and the creation of any public nuisance. If,

in the course of conducting services under this Agreement, Contractor encounters adverse environmental conditions that could reasonably be expected to give rise to liability for United or Contractor under any Environmental Laws or which otherwise could reasonably be expected to result in harm to human health or the environment, Contractor shall promptly notify United of such conditions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Contractor shall, at its own expense, conduct its operations in compliance with applicable Environmental Laws, including obtaining any needed government or applicable airport authority permits or authorizations for Contractor's operations. If United provides any information, instruction, or materials to Contractor relating to its obligations under any Environmental Laws, Contractor agrees that this shall not in any way relieve Contractor of its obligation to comply with Environmental Laws. Contractor further agrees that it shall otherwise preserve the proprietary nature of any such information that is identified by United as proprietary and confidential and shall use its commercially reasonable efforts to ensure that the information is not disclosed to any third parties without first obtaining the written consent of United.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) Contractor shall use its commercially reasonable efforts to perform its services under this Agreement so as to minimize the unnecessary generation of waste materials, including consideration of source reduction and re-use or recycling options, and coordination with United on a cabin service recycling program. If requested by United, Contractor shall replace specific products used in its operations with less toxic products, as long as there is concurrence between Contractor and United as to the relative toxicity of the two products, and a reasonable replacement is available at a similar cost, or if the product is not at a similar cost, provide United the option to agree to pay the difference. If requested by United, Contractor shall take reasonable efforts to provide quantitative data on materials recycled and waste disposed to facilitate coordination and enhancement of cabin service recycling where feasible. Contractor shall ensure that any waste materials generated in connection with the services performed by Contractor under this Agreement are managed in accordance with all applicable Environmental Laws, with Contractor assuming responsibility as the legal generator of such wastes; *provided*, however, this provision does not apply should United or another vendor of United be the entity who has, in fact, independently generated the wastes, in which case, United shall ensure that any waste materials generated in connection with the services performed by Contractor under this Agreement are managed in accordance with all applicable Environmental Laws.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) For any leased areas or other equipment that are jointly used or operated by both Contractor and United (and/or other United contractors), each of United and Contractor shall use its respective commercially reasonable

------

***Execution Version***

efforts to coordinate its activities (and, the activities of any contractor of such party) with the other party to ensure compliance with applicable Environmental Laws.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) Except for de minimis amounts of Hazardous Materials which are promptly and fully remediated to pre-existing conditions, Contractor shall promptly notify United of any spills or leaks of Hazardous Materials attributable to Contractor and arising out of Contractor's provision of services under this Agreement, and, if requested, shall provide copies to United of any written reports provided to any governmental agencies and airport authorities under any Environmental Laws regarding same. Contractor shall promptly undertake all reasonable commercial actions to remediate any such spills or leaks to the extent Contractor is required to do so by applicable Environmental Laws, by the relevant airport authority, or in order to comply with a lease obligation. In the event that Contractor fails to fulfill its remediation obligations under this paragraph and United may otherwise be prejudiced or adversely affected (such as involving United leased property), United may undertake such actions as are reasonable at the cost and expense of Contractor, but only after notifying Contractor in writing of its intention to take such actions. Such costs and expenses shall be promptly paid upon Contractor's receipt of a written request for reimbursement for them by United.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) Contractor shall promptly provide United with written copies of any notices of violation issued or other claims from a third party asserted pursuant to Environmental Laws or associated with a potential release of Hazardous Materials and related to or associated with the provision of services by Contractor under this Agreement. Contractor shall promptly undertake all actions necessary to resolve such matters that are attributable to Contractor, including, without limitation, the payment of fines and penalties, and promptly addressing any noncompliance identified; *provided*, however, that Contractor may contest any notice of violation or other alleged violation and defend any claim that it believes is untrue, improper or invalid. In the event that Contractor fails to fulfill its obligations under this paragraph and United may otherwise be prejudiced or adversely affected, United may undertake such actions as are reasonable or legally required at the cost and expense of Contractor, but only after notifying Contractor in writing of its intention to take such actions. Such costs and expenses shall be promptly paid upon Contractor's receipt of a written request for reimbursement for them by United.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii) If requested by United, Contractor shall conduct a review and provide information to United regarding Contractor's compliance with the requirements of this <u>Section 4.19</u>. This review may include the completion of an environmental compliance audit of Contractor's activities or an

------

***Execution Version***

environmental site assessment, each subject to a work plan approved by United. United shall be responsible for the costs of any such audit or site assessment, unless such audit or assessment reveals a material violation of Contractor's obligations under this <u>Section 4.19</u>, in which case Contractor shall be responsible for the costs of such audit or assessment. Contractor shall provide United with a summary of the results of this audit, provide United an opportunity to review any report generated in connection with such an audit, and will promptly use its commercially reasonable efforts to address any noncompliance or liability identified.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii) In the event that Contractor Services include providing bulk (nonbottled) potable water for crew or passenger consumption, Contractor shall ensure compliance with the Aircraft Drinking Water Regulation, FDA requirements, and other similar applicable laws (collectively, the " <u>Drinking Water Requirements</u> "), including without limitation using its commercially reasonable efforts to ensure all water handling equipment is properly and regularly disinfected and kept in sanitary condition. If Contractor relies upon another contractor to load water onto its aircraft or to maintain water handling equipment, it shall inquire with such contractors to ensure they meet these Drinking Water Requirements as well. Contractor shall immediately notify United if it becomes aware of practices or conditions that may reasonably be expected to negatively impact potable water quality, regardless of the provider or the source of such potable water (including whether such source is an airport, ground handler or aircraft water system). If United provides such water, United shall ensure that such water, when provided, is in compliance with Drinking Water Requirements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ix) Contractor shall maintain records relating to its compliance with Environmental Laws under this Agreement for the [\*\*\*] such period of time as is required by Environmental Laws. Contractor shall, at the request of United and with reasonable advance notice, provide United with reasonable access to Contractor's operations, documents, and employees for the sole purpose of allowing United to assess Contractor's compliance with its obligations with this <u>Section 4.19</u>, including responding to reasonable information requests. Nevertheless, United shall not disclose or report its findings and conclusions of any such assessment to any third party without the prior written consent of Contractor, such consent not to be unreasonably withheld in light of the circumstances; *provided*, that United shall be entitled to make such disclosures as are required by law, stock exchange regulation or applicable lease agreement, in which case United shall provide Contractor with advance notice of such disclosure to the extent practicable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(x) Upon the termination of operations at a space used to support the provision of Contractor Services under this Agreement, Contractor shall

use its commercially reasonable efforts to ensure the removal and proper management of any and all Hazardous Materials associated with Contractor's operations (including its subcontractors) and will comply with any other applicable Environmental Laws applicable to the provision of Contractor Services.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xi) Contractor has reviewed United's Environmental Commitment Statement (found at www.united.com/ecoskies) and agrees to reasonably cooperate with United in meeting these commitments in effect as of the date hereof and in responding to reasonable information requests.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xii) All notices to be provided by Contractor to United under this <u>Section 4.19</u> shall be provided as indicated in <u>Section 11.2</u> of this Agreement, with a copy to Managing Director–Environmental Affairs, United Airlines, Inc., 233 South Wacker Drive-WHQSE, Chicago, IL 60606.

To effect the performance of the Ground Handling Services, United at its sole option and in its sole discretion may from time to time (i) perform all Ground Handling Services directly, (ii) contract with Contractor pursuant to a separate ground handling agreement, or (iii) sub-contract with an affiliate of United or a third party vendor, or any combination of any of the foregoing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Contractor shall use commercially reasonable efforts to cooperate with any provider of Ground Handling Services in order to facilitate efficient, cost effective, and safe operations and to ensure compliance with all applicable laws. United, at United's cost and expense, shall provide all necessary training (including cargo training) to enable United (or United's designee) to provide all ground handling and related services with respect to the operation of the Covered Aircraft for Scheduled Flights; *provided* that Contractor at its cost and expense shall provide all necessary training for the personnel who are responsible for training ground handling personnel who, in turn, are responsible for aircraft handling (i.e. "train the trainers").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)In connection with Contractor's provision of Contractor Services to United under this Agreement, Contractor shall adopt and comply with, and shall cause its employees to adopt and comply with, and shall be responsible for United's direct costs resulting from Contractor's compliance with, all applicable procedures, including without limitation training procedures, as required by United's provision of Ground Handling Services as provided in <u>Section 4.21(a)</u> above.

**INSURANCE**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.1 <u>Minimum Insurance Coverages</u>.

During the Term, in addition to any insurance required to be maintained by Contractor pursuant to the terms of any aircraft lease, or by any applicable governmental or airport authority, Contractor shall maintain, or cause to be maintained, in full force and effect policies of insurance with insurers of recognized reputation and responsibility, in each case to the extent available on a commercially reasonable basis, as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Comprehensive aircraft hull and liability insurance, including aircraft third party, passenger liability (including passengers' baggage and personal effects), cargo and mail legal liability, personal injury and all-risk ground and flight physical damage, with a combined single limit of not less than [\*\*\*] per occurrence and a minimum limit in respect of personal injury for non-passengers of [\*\*\*] per occurrence and in the aggregate, and hull and liability war risk and other perils insurance with a combined single limit no less than [\*\*\*] per occurrence; *provided*, that with respect to war risk insurance acquired from the United States government, the commercial general liability coverage (crew and passengers) of such policy may have such lower combined single limit as is the maximum limit issued by the government from time to time;

***Execution Version***

United shall retain the right at any time to review the coverage, form, and amount of the insurance required hereby. If, in the reasonable opinion of United, the insurance provisions in this Agreement do not provide adequate protection for United and/or the aviation operations of Contractor associated with the Covered Aircraft, United may require Contractor to obtain insurance sufficient in coverage, form, and amount to provide adequate protection for a business organization of Contractor's size and nature; provided, that such insurance is materially similar to insurance then held by regional airlines similarly situated with Contractor. United's requirement shall be commercially reasonable but shall be designed to assure protection from and against the kind and extent of risk which exists at the time a change in insurance is required (provided such protection is available on commercially reasonable terms). Contractor agrees to obtain such insurance at the annual renewal of Contractor's policy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.2 <u>Endorsements</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)To provide that United, UCH, and their respective directors, officers, agents, employees and other authorized representatives shall be endorsed as additional insured parties as respects operations of the named insured and liability coverage (other than as to workers compensation, employers liability and property insurance);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)To include a breach of warranty provision in favor of the additional insureds;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)To accept and insure Contractor's hold harmless and indemnity undertakings set forth in this Agreement, but only to the extent of the coverage afforded by the policy or policies; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)To provide that such policies shall not be canceled, terminated or adversely materially altered, changed or amended until thirty (30) days (but seven (7) days or such lesser period as may be available in respect of hull, war and other perils) after written notice shall have been sent to United.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.3 <u>Evidence of Insurance Coverage</u>.

Any Indemnifying Party shall be subrogated to the rights of the Indemnified Party to the extent that the Indemnifying Party pays for any loss, damage or expense suffered by the Indemnified Party hereunder.

In the latter event, the Indemnified Party, by proceeding to defend itself or settle the matter, does not waive any of its rights hereunder to later seek reimbursement from the Indemnifying Party. With respect to all other claims, the Indemnifying Party shall promptly make payment of such claim upon receipt of reasonably sufficient evidence supporting such claim; *provided*, that if the Indemnifying Party in good faith disputes all or part of its obligation to indemnify the Indemnified Party hereunder or the amount involved, the senior management of each party shall meet to discuss and attempt to resolve such dispute between the parties and, if such dispute is not resolved within [\*\*\*] days of such claim being made, then the parties may pursue other remedies.

***Execution Version***

Contractor is duly qualified to do business as a foreign corporation under the laws of each jurisdiction that requires such qualification.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Authority Relative to this Agreement</u>. Contractor has the corporate power and authority to execute and deliver this Agreement and to consummate the transactions contemplated hereby in accordance with the terms hereof. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly authorized by all necessary corporate action on the part of Contractor. This Agreement has been duly and validly executed and delivered by Contractor and is, assuming due execution and delivery thereof by United and that United has legal power and right to enter into this Agreement, a valid and binding obligation of Contractor, enforceable against Contractor in accordance with its terms, except as enforcement hereof may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting the enforcement of creditors' rights generally and legal principles of general applicability governing the availability of equitable remedies (whether considered in a proceeding in equity or at law or otherwise under applicable law).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)<u>Conflicts; Defaults</u>. Neither the execution or delivery of this Agreement nor the performance by Contractor of the transactions contemplated hereby will (i) violate, conflict with, or constitute a default under any of the terms of Contractor's certificate of incorporation, by- laws, or any provision of, or result in the acceleration of any obligation under, any material contract, sales commitment, license, purchase order, security agreement, mortgage, note, deed, lien, lease or other agreement to which Contractor is a party or by which it or its properties or assets may be bound, (ii) result in the creation or imposition of any lien, charge or encumbrance in favor of any third person or entity, (iii) violate any law, statute, judgment, decree, order, rule or regulation of any governmental authority or body, or (iv) constitute any event which, after notice or lapse of time or both, would result in such violation, conflict, default, acceleration or creation or imposition of liens, charges or encumbrances.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>No Existing Default</u>. Contractor is not (i) in violation of its charter or by-laws, (ii) in breach or default in any material respect, and no event has occurred which, with notice or lapse of time or both, would constitute such a breach or default, in the due performance or observance of any material term, covenant or condition contained in any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which it is a party or by which it is bound or to which any of its properties or assets is subject or (iii) in violation of any law, ordinance, governmental rule, regulation or court decree to which it or its property or assets may be subject or has failed to obtain any material license, permit, certificate, franchise or other governmental authorization or permit necessary to the ownership of its property or to the conduct of its business, in each case of <u>clauses (i)</u>, <u>(ii)</u> or <u>(iii),</u> where such violation, breach, default or failure would have a material adverse effect on Contractor or on its ability to provide Regional Airline Services and otherwise perform its obligations hereunder. To the knowledge of Contractor, Embraer is not in default in any material respect under the Embraer Purchase Agreement, and there is currently no reasonable expectation by Contractor that Actual Delivery Dates for the Covered Aircraft pursuant thereto will be materially delayed beyond the respective Scheduled Delivery Dates set forth on <u>Schedule 1A</u>.

Contractor has not received notice of cancellation or non-renewal of such insurance. All such insurance is outstanding and duly in force on the date hereof. Contractor has no reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not have a material adverse effect on Contractor.

Each Call Option Notice delivered by United shall specify the Call Option Aircraft that are subject to such notice; *provided* that in the case of a termination pursuant to <u>Section 2.4</u>, the Call Option Removed Aircraft shall be those Covered Aircraft with the earliest Actual In-Service Dates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) <u>Lease Aircraft</u>. If United delivers (or is deemed to have delivered) a Call Option Notice, then:

other related documents associated with the lease financing of such Call Option Aircraft, together with a full release (the "<u>Release</u>") of Contractor and Parent from any and all obligations under such agreements for periods following the assignment date (such lease agreement, guaranty and other related documents, the "<u>Lease Documents</u>"). Such assignment and assumption agreement shall contain the Release and shall otherwise be in a form reasonably acceptable to Contractor and United and shall contain the provisions provided in <u>clause (C)</u> below (such agreement, "<u>Assignment and Assumption Agreement</u>").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) United and Contractor shall enter into an Assignment and Assumption Agreement for each Call Option Aircraft specified by United in the Call Option Notice, or for each Call Option Removed Aircraft, as the case may be.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(x) the lien attributable to the lease and (y) any other lien attributable to the lessor or other financing party of the Covered Aircraft. The effective date of such assignment shall occur on a date determined by United, which date shall [\*\*\*] following the removal from the terms of this Agreement of such Call Option Aircraft or Call Option Removed Aircraft, as the case may be (taking into account the Wind-Down Schedule).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(C) Each of the following provisions shall apply and shall be provided for in the Assignment and Assumption Agreement: (u) United will indemnify Contractor against all liabilities and obligations related to facts or circumstances arising from and after such assignment,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v)Contractor shall indemnify United from all liabilities and obligations related to facts or circumstances arising prior to the date of the assignment, (w) at the time of the execution of the Assignment and Assumption Agreement, Contractor shall transfer to United, and United shall take possession of, all deposits or reserves held by the Lessor, (x) United shall assume all obligations of Contractor as above provided with respect to such lease as of the date of assignment and adjustments shall be made between the parties for advance or arrears payment of rent, and (y) Contractor shall assign, to the extent assignable, all warranties relating to such Call Option Aircraft provided by the applicable manufacturer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(D) Notwithstanding United's exercise, or deemed exercise, of the Call Option, United may not exercise such Call Option with respect to any leased Call Option Aircraft (including any leased Call Option Removed Aircraft), or the termination right provided for in <u>Section 2.4(a)</u> or <u>(b)</u> with respect to any leased Call Option Removed Aircraft, in each case unless United or Contractor obtains an

------

***Execution Version***

Assignment and Assumption Agreement relating to such aircraft that has been fully executed by all of the parties thereto (a "<u>Consent</u>") [\*\*\*] following the delivery (or deemed delivery) of such Call Option Notice. Notwithstanding United's deemed exercise of the Call Option following a termination pursuant to <u>Section 2.4(a)</u> or <u>(b)</u>, United shall not be required to exercise the Call Option with respect to any leased Call Option Removed Aircraft following such a termination if, at such time, any material default shall exist under the relevant lease or financing agreement with regard to such leased Call Option Removed Aircraft. If (x) the circumstances described in the first sentence in this <u>Section 10.1(b)(v)(D)</u> occur, or (y) the circumstances described in the second sentence in this <u>Section 10.1(b)(v)(D)</u> occur and United chooses not to exercise such Call Option [\*\*\*] following the delivery (or deemed delivery) of the relevant Call Option Notice, then the Call Option shall terminate as to such leased Call Option Aircraft or leased Call Option Removed Aircraft, as the case may be (in each case subject to United's rights in <u>Section 10.1(b)(v)(E)</u> below).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(E) If (i) (a) a Call Option with respect to a leased Call Option Removed Aircraft terminates pursuant to <u>Section 10.1(b)(v)(D)</u>, or (b) neither United nor Contractor has received a [\*\*\*] following the delivery of a Call Option Notice, or (c) prior to the time that Contractor or United receives a Consent, United determines that obtaining such Consent is unlikely to occur in a timely manner, or (d) if a material default shall exist under the relevant lease or financing agreement with regard to a leased Call Option Aircraft, and, in each case, (ii) if fewer than all of the Call Option Aircraft are then subject to the Call Option Notice or are Call Option Removed Aircraft, as applicable, then (X) if the circumstances apply to a Call Option Aircraft other than Call Option Removed Aircraft, United may promptly select another Call Option Aircraft to substitute for such aircraft, (Y) if the circumstances apply to a Call Option Removed Aircraft, then the Covered Aircraft with the next earliest Actual In-Service Date and that is not already a Call Option Removed Aircraft shall be substituted for such aircraft, and (Z) in each case the procedures set forth in this <u>Section 10.1</u> shall be implemented with respect to such substituted aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) <u>Owned Aircraft</u>. Contractor shall sell all Call Option Removed Aircraft that are owned by Contractor to United for a purchase price equal to the greater of the [\*\*\*] of such aircraft. Contractor shall sell all Call Option Aircraft (other than Call Option Removed Aircraft) that are both specified by United in any Call Option Notice and owned by Contractor to United for a purchase price equal to greater of the [\*\*\*] of such aircraft. United

***Execution Version***

shall further pay any costs incurred by Contractor attributable to any swap breakage or prepayment fees arising from agreements provided to United pursuant to <u>Section 10.1(b)(iii)</u> above, or other similar costs and expenses reasonably incurred by Contractor in connection with the foregoing. In connection with such sale to United, Contractor shall deliver such aircraft to United, without recourse or warranty, on an "as is, where is, and with all faults basis" (except as to the absence of liens and encumbrances). The effective date of such sale shall occur on a date determined by United, which date shall occur before the later of (x) the [\*\*\*] following the removal of the applicable Covered Aircraft from the terms of this Agreement (taking into account the Wind-Down Schedule), and (y) the [\*\*\*] following United's delivery (or deemed delivery) of a Call Option Notice.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii) Contractor shall not discriminate in its operation or maintenance of its aircraft (including without limitation with respect to any swapping or removal of parts, components or engines) based on United's ability to exercise, or actual exercise of, a Call Option in respect to any aircraft and shall continue to comply with the provisions of <u>Article IV</u> hereto as they relate to each aircraft prior to the effective date of such sale.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.2 <u>Extension of Aircraft Term</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)At any time and from time to time, but not less than [\*\*\*] prior to the existing exit date for any Covered Aircraft, and at its sole option, United may extend the exit date for any Covered Aircraft (which, subject to the terms of this <u>Section 10.2</u>, shall extend the capacity purchase provisions hereof with respect to such Covered Aircraft to such later exit date) by delivering to Contractor a written notice of extension, which notice shall include a revised <u>Schedule 1</u> reflecting such later exit date (any such notice, an "<u>Extension Notice</u>"); *provided* that (1) no extension of the exit date of a leased Covered Aircraft shall be permitted by United hereunder if Contractor does not have the unilateral right to extend such lease term to a date coincident with or subsequent to the resulting exit date on the same (or better) terms and conditions as the lease then in effect; (2) Contractor shall be deemed to have the unilateral right to extend such lease term if United and Contractor's lessor shall have negotiated a lease extension to a date coincident with the resulting exit date at a lease cost not in excess of the "ownership rate per month for each Covered Aircraft" on <u>Schedule 2</u>, which lease extension shall otherwise be on the same terms and conditions as the lease being extended; (3) any extension shall be made only in increments of [\*\*\*]; (4) that the exit date for any Covered Aircraft may be extended [\*\*\*]; and (5) that in no event shall United's exercise of its extension rights pursuant to the provisions in this <u>Section 10.2</u> result in Contractor operating [\*\*\*] Covered Aircraft in its provision of Regional Airline Services to United under this Agreement. Within fifteen (15) days of receipt by Contractor of an Extension Notice from United, Contractor shall present to United a written good faith approximation of Contractor's projected future costs of operation during the applicable extension period and a proposed revised <u>Schedule 2</u> to reflect such projected future costs. Within [\*\*\*] of United's receipt of such approximation and proposed revised <u>Schedule 2</u> from Contractor, United shall inform Contractor in writing whether,

------

***Execution Version***

United, in its sole discretion, has either confirmed or rescinded such extension. Upon any such confirmation by United (a "<u>Confirmation Notice</u>"), the Compensation for Carrier Controlled Costs shall be adjusted to reflect Contractor's approximation of projected future costs of operation during the applicable extension period and such costs shall be reflected on the revised <u>Schedule 2</u> proposed by Contractor. Upon delivery of a Confirmation Notice to Contractor, the revised <u>Schedule 1</u> included in the Extension Notice and Contractor's proposed revised <u>Schedule 2</u> shall be incorporated into this Agreement without any further action by any party and shall thereafter constitute the amended and restated <u>Schedule 1</u> and <u>Schedule 2</u> for all purposes of this Agreement. Upon any determination by Contractor not to renew any lease for any Covered Aircraft, Contractor shall promptly notify United. During any extension period pursuant to this <u>Section 10.2(a)</u>, Contractor shall promptly inform United of any material changes in the terms of any leases subject to the extension and shall keep United reasonably informed of the status of any negotiations between Contractor and Contractor's lessor in connection with a proposed extension of the term of any lease.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)United may at any time and from time to time propose to extend the exit date for any Covered Aircraft to Contractor through mutually-agreed modification of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.3 <u>Alternative Aircraft</u>.

At any time that United desires to utilize aircraft other than the Covered Aircraft, Contractor and United agree to meet and discuss in good faith the appropriate adjustments to this Agreement necessary to include such other aircraft as a Covered Aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.4 <u>Additional Aircraft</u>.

United shall have the right in its sole discretion at any time and from time to time during the Term to amend <u>Schedule 1</u> unilaterally to increase the number of Covered Aircraft (any such additional aircraft, the "<u>Growth Aircraft</u>") utilized by Contractor for Regional Airline Services (such right, the "<u>Growth Aircraft Option</u>"); *provided* that the following provisions shall apply:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)in order to exercise the Growth Aircraft Option, United must provide Contractor with written notice of United's election of the Growth Aircraft Option (the "<u>Growth Aircraft Option Notice</u>"), which notice shall include the date of first use of any Growth Aircraft for Regional Airline Services, such date to be at least [\*\*\*] the date of the Growth Aircraft Option Notice; *provided* that, unless otherwise agreed by the parties, United shall not exercise the Growth Aircraft Option [\*\*\*];

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)the Growth Aircraft shall be of an aircraft type equivalent to the aircraft type set forth on <u>Schedule 1</u> (or an acceptable substitute aircraft agreed to by United and Contractor);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)the maximum number of Growth Aircraft shall be [\*\*\*];

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)the Growth Aircraft shall be provided to Contractor by United pursuant to a Covered Aircraft Sublease with such changes as (i) are necessary to conform to the requirements of the head lease and related financing documents for such Growth Aircraft,(ii) are mutually agreed to by Contractor and United and (iii) provisions relating to return conditions and storage

**Catering Standards**

**INFLIGHT PRODUCT SALES PROGRAM**

United will market a portfolio of inflight products for purchase on United Express flights which includes liquor, beer, wine, food, or other product offerings. Contractor will administer the program related to such in-flight sales (the "<u>Inflight Product Sales Program</u>") as United's representative following all policies and procedures of United. The initial policies and procedures established by United for the sale of products onboard Contractor's flights under the Agreement with United are set forth below. United reserves the right to change the product offerings, policies and procedures associated with the Inflight Product Sales Program at any time and in its sole discretion.

**Station Services**

● United, or United's catering agent, will provide catering services as directed by United.

● United or its catering agent will provide and stock in galley supplies, including, food, liquor, other beverage, and other product uplift as necessary and will remove, store and re-board perishable supply and beverage items on Remain Over Night (RON)/originating flights at airports designated by United as catering airports.

● In respect of all catering items (including the Inflight Product Sales Programs), Contractor will coordinate and communicate with United or United's catering agent regarding all flight activity, cancellations and irregular operations providing necessary information in a timely manner.

**Onboard Services**

● United has right to determine meal/beverage and other product offering service parameters and scheduling for Scheduled Flights.

***Execution Version***

● Contractor will provide, at Contractor's cost and expense, the initial galley service ship's equipment to operate, such as beverage carts, trays, hot jugs, coffee makers and trash bins, carts, carrier boxes, drawers, inserts and oven racks. United shall provide, at United's cost and expense, the replacement as needed of the foregoing; *provided* that if United shows that such replacement was needed due to damage caused by Contractor's negligence or willful misconduct, then Contractor, not United, shall pay for the costs of such replacement.

● United will provide all liveried catering items, including cups, napkins, etc. as well as all products in the Inflight Product Sales Program.

**TECHNOLOGY**

The sale of product onboard Contractor's flights under the Agreement will involve non-cash transactions. United will provide a single hand held device (each such device, an "<u>HHD</u>" and collectively, the "<u>HHD units</u>") necessary to process credit and debit card transactions for each aircraft in Contractor's fleet operating as United Express. Contractor shall only swipe the customer's credit or debit card into the HHD unit for the purpose of processing the customer's transaction and shall not otherwise use or record the customer information. The HHD units provided by United shall only be used for United's business purposes.

The HHD units and the information contained therein shall be deemed the confidential and proprietary information of United and its licensors and shall be subject to the confidentiality terms and conditions set forth in the Agreement for other types of confidential information of United. Contractor shall not, and shall not permit others to, reverse engineer, decompile, disassemble or translate the HHD units, including any firmware or software that is loaded upon the units, or otherwise attempt to view, display or print the source code embedded in the HHD units, or any firmware or software loaded on the HHD units.

Upon the earlier to occur of (i) the termination of United's Inflight Product Sales Program,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the termination of this Agreement, or (iii) the cessation of the use of the HHD units by Contractor, as determined by United in its sole discretion, Contractor shall cooperate with United or its designated vendor for the collection and return of all HHD units to United at the address designated by United, at United's cost. Contractor shall return the HHD units in its possession in as good a condition as reasonably possible, except for reasonable wear and tear thereof.

Contractor shall use commercially reasonable efforts to keep secure the HHD on each aircraft. Contractor agrees to notify United whenever any HHD unit has been, or Contractor reasonably believes or suspects that any HHD unit has been, lost, acquired, destroyed, modified, used, disclosed or accessed by any person in an unauthorized manner or for an unauthorized purpose (collectively, "<u>Security Breach</u>"). Contractor further agrees to provide all reasonable assistance requested by United or United's designated representatives, in the furtherance of any correction, remediation, investigation, enforcement or litigation with respect to a Security Breach, including but not limited to, any notification that United may determine appropriate to send to individuals impacted or potentially impacted by a Security Breach.

Exhibit G-2

------

***Execution Version***

Lost equipment will be replaced by United. Replacement costs will be borne by Contractor to the extent such equipment is lost due to the negligence of Contractor and the cost exceeds the annual HHD loss allowance (as hereinafter defined). Any equipment that is unaccounted for and for which no transactions have been logged for 48 hours will be considered "lost" and, if United shows that such equipment is lost due to Contractor's negligence, United reserves the right to set-off the replacement cost of such lost equipment that is in excess of the annual HHD loss allowance by taking a credit of such excess replacement cost pursuant to the procedures set forth in <u>Section 11.13</u> of the Agreement.

Any HHD unit that is damaged beyond reasonable wear and tear which is shown by United to be due to Contractor's negligence, and in excess of the annual HHD loss allowance, will be replaced at Contractor's expense. United reserves the right to set-off the replacement cost associated with such damaged HHD unit, if in excess of the annual HHD loss allowance, by taking a credit of such excess replacement cost pursuant to the procedures set forth in <u>Section</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>11.13</u> of the Agreement.

The "annual HHD loss allowance" referred to above shall be an amount equal to [\*\*\*] of the value of all HHD units on Contractor's United Express flights, on a calendar-year basis. All loss procedures established by United, and reasonably agreed to by Contractor, must be adhered to by Contractor.

United, at its cost, will provide or cause to be provided by a vendor of United's choice the maintenance and battery replacement for the HHD units. Such maintenance and battery replacement will be provided at predetermined intervals designed to maximize HHD and battery useful life, and Contractor will have the right to request maintenance at different times than the predetermined intervals or additional battery replacement at United's cost upon request. In the event Contractor's request for maintenance is related to a faulty or defective HHD unit, United shall pay the vendor directly for such non-routine service call.

United will provide at its sole cost and expense (including all out of pocket costs and reimbursement of Contractor's labor costs) for initial "train the trainer" training to a reasonable number of Contractor-designated "trainers" on the use of the HHD. Such cost will be negotiated and agreed upon by the parties. Contractor will be required to (i) retain the training skill beyond the initial "train the trainer" training provided by United and (ii) provide training to Contractor's crew personnel at Contractor's own expense.

**PRODUCT LOSS AND PILFERAGE**

United will establish procedures aimed at limiting product loss. At a minimum, it is required that Contractor's Flight Attendants record opening and closing inventories of each product to be sold onboard, accounting for all sales and complimentary items distributed.

Seals may be required to prevent tampering with product inventories and to deter pilferage. United will monitor all inventories and reserves the right to charge Contractor for identified loss due to Contractor's negligence (including breakage and other damage) and pilferage on a cost

***Execution Version***

(non mark-up) basis determined monthly, for any amounts in excess of the monthly product loss allowance (as hereinafter detailed). Any discrepancies in inventories, seal numbers recorded, or excessive complimentary activity for any product sold must be reported at the hub for use in pilferage investigations by United. Contractor's failure to provide documentation as reasonably requested by United or its representatives will result in Contractor being charged for pilferage as reasonably determined by United on a cost basis. United reserves the right to set off the excess value of the loss and/or pilferage caused by Contractor on a cost (non mark-up) basis if in excess of the monthly loss allowance, by taking a credit of such excess loss and/or pilferage pursuant to the procedures set forth in <u>Section 11.13</u> of the Agreement. All reasonable product loss and pilferage procedures established by United must be adhered to by Contractor.

The "monthly product loss allowance" referred to above shall be an amount equal to [\*\*\*] of the value of all beverage or food or other product markets on Contractor's United Express flights, on a monthly basis. All loss allowance procedures established by United, and reasonably agreed to be Contractor, must be adhered to by Contractor.

United may, at any time during normal operating hours inspect, monitor, or audit Contractor's administration of the Inflight Product Sales Program described in this Appendix or in other policies and procedures, in order to verify that Contractor is in compliance, in all material respects, with United's requirements for the Inflight Product Sales Program. Contractor will work with United to ensure reasonably appropriate controls exist designed to comply with United's requirements and will ensure corrective actions are in place as necessary.

**LIQUOR, BEER AND WINE PROGRAM**

The Alcoholic Beverage Products offering will be determined by United and provided for by United in the liquor kit supplied to each aircraft. Except as prohibited by law or otherwise agreed by United and Contractor due to the various applicable liquor license laws and regulations, the Alcoholic Beverage Products will be purchased by United prior to being placed onboard Contractor's aircraft and sold onboard all United Express flights designated by United.

Once onboard Contractor's aircraft, liquor drawers, bags or other liquor containment mechanisms used by Contractor, as determined by Contractor, are considered a part of ship's equipment and will be used for the distribution of United's inflight products.

Contractor shall not serve any Alcoholic Beverage Product(s) on the ground without United's consent. Contractor will obtain and maintain, at United's cost and expense, the necessary liquor licenses in the states where they board and/or unload any Alcoholic Beverage Product. Unless otherwise agreed by the parties, Contractor will not board or unload any Alcoholic Beverage Products in Virginia but in the event it is agreed that Contractor will board or unload any Alcoholic Beverage Products in Virginia, the parties shall comply with the procedures for Virginia below.

Exhibit G-4

***Execution Version***

**Virginia Alcoholic Beverage Handling Procedures**

Contractor will comply with Virginia's liquor purchase procedures. In Virginia, Contractor will board and/or unload only Alcoholic Beverage Products that Contractor owns. To that end, in the event it is agreed by the parties that Contractor will board and/or unload any Alcoholic Beverage Products in Virginia, Contractor will purchase such Alcoholic Beverage Products directly. Contractor will timely pay the supplier of such Alcoholic Beverage Products directly for such order(s). Once out of Virginia airspace, Contractor will transfer to United the title to the purchased Alcoholic Beverage Products. United will be responsible for any sales tax attributable to the foregoing title transfer, as well as the costs associated with the acquisition of such liquor.

**Compliance**

United agrees that it shall comply with all applicable federal, state, and local laws, rules and regulations and United, based upon its activities occurring at a given location, shall obtain and maintain all permits, certifications and licenses necessary for the conduct of its operations relating to the purchase, distribution, storage or provision of any Alcoholic Beverage Product by United.

**FOOD AND OTHER PRODUCTS**

All capitalized terms used herein and not otherwise defined shall have the meanings ascribed to such terms in the CPA (as defined below).

**RECITALS**

WHEREAS, concurrently with the execution of this Guaranty Agreement, SkyWest Airlines, Inc., a Utah corporation ("<u>Contractor</u>"), and Guaranteed Party are executing that certain Capacity Purchase Agreement (the "<u>CPA</u>") dated as of even date herewith and the Ancillary Agreements;

WHEREAS, pursuant to the CPA and the Ancillary Agreements, Contractor agrees to perform certain obligations and provide certain services to Guaranteed Party, in each case as more fully set forth therein;

WHEREAS, Contractor is a direct wholly-owned subsidiary of Guarantor; and WHEREAS, Guarantor is fully informed, understands and acknowledges that it is a

requisite inducement for Guaranteed Party to enter into the CPA and the Ancillary Agreements that Guarantor execute and deliver this Guaranty Agreement (as the same may be amended or supplemented from time to time, herein referred to as this "<u>Guaranty</u>").

NOW, THEREFORE, in consideration of the benefits, rights and interests to Contractor derived from the CPA and the Ancillary Agreements, for a necessary inducement to the Guaranteed Party to enter into the CPA and the Ancillary Agreements, and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, Guarantor, fully aware that the Guaranteed Party is relying hereupon, hereby agrees as follows:

<u>SECTION 1</u>. <u>Guaranty of Obligations</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Guarantor unconditionally, absolutely and irrevocably guarantees that Contractor shall perform and observe each agreement, covenant, obligation, term and condition of the CPA and the Ancillary Agreements (collectively, the "<u>Performance Obligations</u>") to be performed or observed by Contractor, and upon Contractor's failure to do so, Guarantor shall promptly perform and observe, or shall cause to be promptly performed and observed, each such Performance Obligation at its sole cost and expense.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Guarantor unconditionally, absolutely and irrevocably guarantees that any and all sums, of whatever character, stated in the CPA and the Ancillary Agreements

Exhibit K-1

------

***Execution Version***

(collectively, the "<u>Payment Obligations</u>," and together with the Performance Obligations, the "<u>Obligations</u>") to be payable by Contractor, shall be timely paid in full when due in accordance with the provisions thereof. Notwithstanding anything to the contrary in this Guaranty, the CPA and the Ancillary Agreements, Guarantor's Obligations with respect to any payment (including without limitation any amount of base compensation, incentive compensation, rent, rebate, penalty or other payment) under <u>Article II</u>, <u>clause (iii)</u> of <u>Section 7.01</u> (other than with respect to any third-party claim), and any similar agreement entered into in accordance with the terms of <u>Section 10.4</u> of the CPA and in each case resulting directly from a Labor Strike, or otherwise resulting directly from the failure to fly any Schedule Flights because of a Labor Strike, shall not in any event [\*\*\*]. This Guaranty is a guaranty of payment and performance, not merely of collection, and is unconditional and absolute in all respects, and if for any reason any Payment Obligation shall not be paid timely when due, Guarantor shall immediately pay the same to the person entitled thereto pursuant to the provisions of the CPA, as if such sums constituted the direct and primary obligation of Guarantor, regardless of whether any person has taken any steps to enforce any rights against Contractor or any other person to collect such sum. This Guaranty shall at all times be valid and enforceable without set off, deduction or counterclaim irrespective of any other agreements or circumstances of any nature whatsoever which might otherwise constitute a defense to this Guaranty or the obligations of Guarantor under this Guaranty.

<u>SECTION 2</u>. <u>Subsequent Occurrences</u>. To the fullest extent permitted under applicable law, the obligations of Guarantor hereunder shall be absolute and unconditional, shall be continuing and independent of, and in addition to, any and all rights and remedies Guaranteed Party may have under the CPA or any Ancillary Agreement and any other guaranties, agreements or documents now or hereafter given in connection therewith by Guarantor or others and remain in full force and effect until final and irrevocable payment or performance, and shall not be released, discharged, affected or impaired in any respect by: (a) any amendment, modification, or cancellation of, or addition or supplement to the CPA or any Ancillary Agreement, including without limitation, any change in the time, manner or place of payment of amounts due under the CPA or any Ancillary Agreement; (b) the entering into, or the modification or amendment in or of, any lease or sublease of any aircraft or engine, any contract or arrangement for the maintenance or refurbishment of any aircraft or engine, any contract or arrangement for the provision of ground handling services, any lease, sublease or other agreement relating to the use of any terminal or non-terminal airport facility, or any loan agreement, note, deed of trust, assignment, contract or other document or agreement entered into by Contractor or Guarantor relating to the provision of regional airline services (together with the CPA and the Ancillary Agreements, the "<u>Documents</u>"); (c) any exercise, acceleration, extension, compromise, settlement, non-exercise, waiver, release, or cancellation by Guaranteed Party of any right, remedy, power or privilege under or related to the Documents or any other guaranty of Contractor obligations; (d) the invalidity or unenforceability, in whole or in part, of any of the Documents; (e) any change in the corporate existence, structure or ownership of Contractor or the Guarantor or any insolvency, bankruptcy, reorganization or other similar proceeding affecting either of them or their assets; (f) any release or waiver of or delay in the enforcement of rights against Contractor, Guarantor or any other person or entity under any of the Documents or against any security thereunder; (g) the exercise by Guaranteed Party of any of its rights or

Exhibit K-2

------

***Execution Version***

remedies under any one or more of the Documents; or (h) any other occurrence, circumstance, happening or event whatsoever, whether similar or dissimilar to the foregoing, whether foreseen or unforeseen, and any other circumstance which might otherwise constitute a legal or equitable defense, release or discharge of the liabilities of a guarantor or surety, or which might otherwise limit recourse against the Guarantor. If acceleration of the time for the performance or payment of any Obligation is stayed upon the insolvency, bankruptcy or reorganization of Contractor, all Obligations that are subject to acceleration under the terms of the CPA and the Ancillary Agreements shall nonetheless be performed or payable hereunder by the Guarantor.

<u>SECTION 3</u>. <u>Waiver</u>. Guarantor hereby specifically agrees that it shall not be necessary or required as a condition to enforcement of the obligations hereunder against it, that there be (and Guarantor, to the fullest extent permitted by applicable law, specifically waives) diligence, presentment, or protest of any kind whatsoever with respect to this Guaranty or the Obligations; such waiver includes, without limitation: (a) presentment for payment upon Contractor or Guarantor or the making of any protest; (b) any requirement to exhaust any remedies exercisable upon a default under the CPA or any Ancillary Agreement or to give any notice of non- performance or non-payment; (c) any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge, release or defense of a guarantor or surety; or (d) so long as any Obligation remains outstanding, any right of subrogation by virtue of any performance or payment made hereunder. Guarantor agrees that any payment or performance of the Obligations guaranteed hereunder or other act that tolls any statute of limitations applicable to enforcement of the Obligations shall similarly operate to toll any statute of limitations applicable to any liability of Guarantor hereunder. In addition, to the fullest extent permitted by applicable law, Guarantor waives the benefit and advantage of any and all valuation, stay, appraisement, extension or redemption laws which, but for this provision, agreement and waiver, might be applicable to any sale made under any judgment, order or decree of any court or otherwise based on this Guaranty. All waivers made by Guarantor in this <u>Section 3</u> and elsewhere throughout this Guaranty are intentional and made by Guarantor after due consideration of all the consequences thereof.

<u>SECTION 4</u>. <u>Representations and Warranties of Guarantor</u>. Guarantor represents and warrants as of the Effective Date and covenants to the Guaranteed Party that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Guarantor is a corporation duly incorporated and validly existing in good standing pursuant to the laws of the State of Utah; and has the corporate power and authority to carry on its business as presently conducted and to enter into and perform its obligations hereunder; and Guarantor is duly qualified to do business as a foreign corporation in each jurisdiction in which its operations or the nature of its business requires such qualification, except where the failure to be so qualified would not have a material adverse effect on its ability to perform its obligations hereunder and under the Guaranty;

Neither this Guaranty nor any other term hereof may be changed, waived, discharged or terminated orally, but only by an instrument in writing signed by the party against which such enforcement of the change, waiver, discharge or termination is sought. The captions are for convenience only and shall in no way affect the manner in which any provision hereof is construed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)This Guaranty is subject to, and will be governed by and interpreted in accordance with, the laws of the State of Illinois, excluding conflicts of laws principles, and of the United States of America. Any action or proceeding seeking to enforce any provision of, or based on any right arising out of, this Guaranty may only be brought in the United States District Court for the Northern District of Illinois (or, if such court does not accept jurisdiction, such action or proceeding may only be brought in any Illinois state court sitting in the County of Cook, Illinois) and each of the parties hereto irrevocably consents to the exclusive jurisdiction of such courts (and of the appropriate appellate courts) in any such action or proceeding and waives, to the fullest extent permitted by law, any objection to venue laid therein. Notwithstanding the preceding sentence, process in any action or proceeding referred to therein may be served by appropriate means on the other party outside of the Northern District of Illinois (or the County of Cook, Illinois, as applicable). Each party further agrees to waive any right to a trial by jury. Because a breach of the provisions of this Guaranty could not adequately be compensated by money damages, any party shall be entitled to an injunction restraining such breach or threatened breach and to specific performance of any provision of this Guaranty and, in

Exhibit K-7

------

***Execution Version***

either case, no bond or other security shall be required in connection therewith, and the parties hereby consent to the issuance of such injunction and to the ordering of specific performance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Any term or provision of this Guaranty that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. No course of dealing between any parties shall change, modify or discharge, in whole or in part, this Guaranty or any of the obligations of Guarantor hereunder. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)This Guaranty has been delivered free of any conditions and, except as otherwise expressly set forth herein, no representations have been made to Guarantor affecting or limiting the liability of Guarantor hereunder except as expressly provided herein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g)No action or proceeding brought or instituted under this Guaranty and no recovery in pursuance thereof shall be a bar or defense to any further action or proceeding which may be brought under this Guaranty by reason of any further default or defaults hereunder or in the performance and observance of the terms, covenants, conditions, and provisions in the Documents.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h)Any and all amounts due and owing by Guarantor to Guaranteed Party hereunder that are not paid in full to Guaranteed Party within [\*\*\*] following the earlier of the due date or demand therefor shall bear interest from the date such amounts were due hereunder until paid in full at a rate equal to [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)Guarantor acknowledges that Guaranteed Party will rely upon this Guaranty in entering into the CPA and the Ancillary Agreements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j)Notwithstanding anything contained herein to the contrary, if the Guarantor hereunder is not the Parent, then nothing in this Guaranty shall prevent the liquidation of the Guarantor or the merger or consolidation of the Guarantor with or into another guarantor (as such term is defined in the CPA).

("<u>United</u>"), are each a party to a Capacity Purchase Agreement dated as of May 16, 2013 (as amended by the parties previously, the "<u>CPA</u>"). Capitalized terms not defined herein shall be defined as provided in the CPA.

United and Contractor each desire to amend the CPA as follows, such amendments to be effective as of November 7, 2014 notwithstanding the date of this Third Amendment written above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. In accordance with Sections 3.6 b.(iii)(A)(7) and 4.12 of the CPA, and subject to the reconciliation provisions of the CPA [\*\*\*].

"Without limiting the foregoing, Contractor and its subcontractors performing services for United on behalf of Contractor hereunder shall abide by the requirements of 41 CFR §§ 60-1.4(a), 60-300.5(a) and 60-741.5(a).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. The following provision is hereby added as a new Subsection 11.17 of the CPA:

"11.17 Unauthorized Payments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) In connection with any performance under this Agreement, neither Contractor, nor any officer, employee, or agent of Contractor, will make any payment, or offer, promise, give or authorize any payment, of any money or other article of value, to any official, employee, or representative of United or any government official or representative, or to any person or entity doing business with United, in order either to obtain business under this Agreement or to retain United's business under this Agreement, or to direct United's business under this Agreement to a third party, or to influence any act or decision of any employee or representative of United as pertaining to this Agreement or any government official or representative to perform or to fail to perform his

------

The parties agree that (i) payments by Contractor to former employees of United in the ordinary course of Contractor's business, together with matters relating to contractual relationships between United and any former employee of United employed by Contractor and (ii) incidental expenses incurred for business meetings, meals and other minor business related expenses shall not, in each case, violate this paragraph (clause (i) and (ii), "<u>Permitted Actions</u>").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In connection with any performance under this Agreement, neither Contractor, nor any officer, employee, or agent of Contractor, will solicit or receive any amount of cash or negotiable paper, or any item, service or favor of value (a "gift") from United.

Contractor acknowledges that in accordance with United's galley cart exchange program, Contractor Equipment as well as the United Supplemental Equipment, if any, will not be specifically assigned to or otherwise designated to the Contractor; rather, they will be rotated among United's mainline aircraft and the aircraft operated by the United Express carriers, as cart exchanges are scheduled by United.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.

As such, Contractor's staff shall ensure that defective or damaged carts and carriers on the aircraft are tagged with the "Galley Equipment Needs Repair" tag.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. Contractor shall use reasonable measures, including appropriate administrative, technical and physical safeguards, to secure the Combined Equipment on each of the aircraft operated by Contractor in its Regional Airline Services and while the Combined Equipment is in the care, control, or custody of Contractor. Contractor agrees to notify United promptly whenever any Combined Equipment in the care, control, or custody of Contractor has been, or Contractor reasonably believes or suspects that any such Combined Equipment has been, lost, damaged or destroyed.

------

Combined Equipment which is lost will be replaced by United at United's cost and expense; provided, the cost of any Combined Equipment procured to replace such lost Combined Equipment will be borne by Contractor to the extent United shows that such Combined Equipment was lost due to Contractor's negligence or willful misconduct. Any Combined Equipment that is unaccounted for will be considered "lost". If the Combined Equipment was last In the care, custody or control of Contractor and has been lost due to Contractor's negligence or willful misconduct, United reserves the right to set-off the cost to replace any such lost Combined Equipment in the manner provided in <u>Section 11.13</u> of the Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. United will provide, at United's cost and expense, the replacement of any damaged or worn out Combined Equipment as needed; provided, that any Combined Equipment that is damaged will be replaced at Contractor's expense if United shows that such replacement was needed due to damage caused by Contractor's negligence or willful misconduct.

Subject to Section 9 below, United acknowledges that the Contractor Equipment is owned solely by Contractor. Contractor shall ensure that any and all United Supplemental Equipment and all other supplies and equipment of United or other United Express carriers that are provided by or on behalf of United in connection with United's Inflight Product Sales Program remain free and clear from any liens attributable to Contractor. United shall ensure that any and all Contractor Equipment remains free and clear from any liens attributable to United. United will use commercially reasonable efforts to require that Contractor Equipment used by other carriers as part of United's cart exchange program will remain free and clear of all liens attributable to such other airline. In the event that any liens not permitted hereunder arise, the responsible party will obtain a bond to fully satisfy such liens or otherwise remove such liens at its sole cost and expense within [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. Upon the earlier to occur of (i) the termination of United's inflight catering service program for United Express flights, as determined by United, (ii) the termination of this Agreement, or (iii) the cessation of the use of the United Supplemental Equipment by the Contractor, as determined by United In its sole discretion (for the sole purposes of this paragraph, such date shall be referred to as the " <u>Service End Date</u> "), Contractor shall cooperate with United or its designated vendor for the collection and return of all United Supplemental Equipment to United at the address designated by United, with such reasonable shipment cost to be borne by United. Contractor shall return the United Supplemental Equipment in its care, custody or control within [\*\*\*] of the Service End Date in the same condition as the condition of the item(s) when Contractor received

------

such United Supplemental Equipment, reasonable wear and tear excepted. United shall bear any reasonable out of pocket shipment cost to return such United Supplemental Equipment to United. United shall only ship United Supplemental Equipment from established catering locations; in the event the United Supplemental Equipment is located at a non-catering location (such as, but not limited to, the Contractor's training facility) then Contractor shall bear the shipment cost to return the United Supplemental Equipment to a catering location. United Supplemental Equipment which is damaged due to Contractor's negligence or willful misconduct when received back by United or its designee will be replaced by United at Contractor's expense. Worn out United Supplemental Equipment shall be considered "damaged" for the purposes of the foregoing sentence if the United Supplemental Equipment has been damaged due to Contractor's negligence or willful misconduct. United reserves the right to set-off the cost associated with the replacement of any such damaged or worn out United Supplemental Equipment in the manner provided in <u>Section 11.13</u> of the Agreement. Notwithstanding the foregoing, in addition, as of the Service End Date, Contractor shall retain or have returned to it one used shipset of Galley Service Equipment equal to the number of Contractor Equipment shipsets provided by Contractor as contemplated herein, subject to reasonable wear and tear, which may or may not be the initial Contractor Equipment initially supplied (any such shipset of Galley Service Equipment, the "<u>Contractor Returned Equipment</u>"), with all such retained or returned Contractor Returned Equipment being retained or returned free and clear of all Hens attributable to United or any other United Express carrier participating in the cart exchange program as provided for in Section 7 hereof. United shall bear any reasonable out of pocket shipment cost to return such Contractor Returned Equipment to Contractor.

Title to any United Supplemental Equipment returned to United or retained by United, or to any Contractor Equipment other than the Contractor Returned Equipment that is returned to United or retained by United, as contemplated herein shall, without further act by either party, vest in United free and clear of any liens attributable to Contractor.

● United will provide all liveried catering items, including cups, napkins, etc. as well as all products in the Inflight Product Sales Program.

**TECHNOLOGY**

------

The sale of product onboard Contractor's flights under the Agreement will involve non-cash transactions. United will provide a single hand held device (each such device, an "<u>HHD</u>" and collectively, the "<u>HHD units</u>") necessary to process credit and debit card transactions for each aircraft in Contractor's fleet operating as United Express. Contractor shall only swipe the customer's credit or debit card into the HHD unit for the purpose of processing the customer's transaction and shall not otherwise use or record the customer information. The HHD units provided by United shall only be used for United's business purposes.

The HHD units and the information contained therein shall be deemed the property of and the confidential and proprietary information of United and its licensors and shall be subject to the confidentiality terms and conditions set forth in the Agreement for other types of confidential information of United. Contractor shall not, and shall not permit others to, reverse engineer, decompile, disassemble or translate the HHD units, including any firmware or software that is loaded upon the units, or otherwise attempt to view, display or print the source code embedded in the HHD units, or any firmware or software loaded on the HHD units.

Upon the earlier to occur of (i) the termination of United's inflight Product Sales Program, (ii) the termination of this Agreement, or (iii) the cessation of the use of the HHD units by Contractor, as determined by United in its sole discretion, Contractor shall cooperate with United or its designated vendor for the collection and return of all HHD units to United at the address designated by United, at United's cost. Contractor shall return the HHD units in its possession in as good a condition as reasonably possible, except for reasonable wear and tear thereof

Contractor shall use commercially reasonable efforts to keep secure the HHD on each aircraft. Contractor agrees to notify United whenever any HHD unit has been, or Contractor reasonably believes or suspects that any HHD unit has been, lost, acquired, destroyed, modified, used, disclosed or accessed by any person in an unauthorized manner or for an unauthorized purpose (collectively, "<u>Security Breach</u>"). Contractor further agrees to provide all reasonable assistance requested by United or United's designated representatives, in the furtherance of any correction, remediation, investigation, enforcement or litigation with respect to a Security Breach, including but not limited to, any notification that United may determine appropriate to send to individuals impacted or potentially impacted by a Security Breach.

Lost equipment will be replaced by United. Replacement costs will be borne by Contractor to the extent such equipment is lost due to the negligence of Contractor and the cost exceeds the annual HHD loss allowance (as hereinafter defined). Any equipment that is unaccounted for and for which no transactions have been logged for 48 hours will be considered "lost" and, if United shows that such equipment is lost due to Contractor's negligence, United reserves the right to set-off the replacement cost of such lost equipment that is in excess of the annual HHD loss allowance by taking a credit of such excess replacement cost pursuant to the procedures set forth in <u>Section 11.13</u> of the Agreement.

Any HHD unit that is damaged beyond reasonable wear and tear which is shown by United to be due to Contractor's negligence, and in excess of the annual HHD loss allowance, will be replaced at Contractor's expense. United reserves the right to set-off the replacement cost associated with such damaged HHD unit, if in excess of the annual HHD loss allowance, by

------

taking a credit of such excess replacement cost pursuant to the procedures set forth in <u>Section</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<u>11.13</u> of the Agreement

The "annual HHD loss allowance" referred to above shall be an amount equal to [\*\*\*] of the value of all HHD units on Contractor's United Express flights, on a calendar-year basis. All loss procedures established by United, and reasonably agreed to by Contractor, must be adhered to by Contractor.

United, at its cost, will provide or cause to be provided by a vendor of United's choice the maintenance and battery replacement for the HHD units. Such maintenance and battery replacement will be provided at predetermined intervals designed to maximize HHD and battery useful life, and Contractor will have the right to request maintenance at different times than the predetermined intervals or additional battery replacement at United's cost upon request. In the event Contractor's request for maintenance is related to a faulty or defective HHD unit, United shall pay the vendor directly for such non-routine service call.

United will provide at its sole cost and expense (including all out of pocket costs and reimbursement of Contractor's labor costs) for initial "train the trainer" training to a reasonable number of Contractor-designated "trainers" on the use of the HHD. Such cost will be negotiated and agreed upon by the parties. Contractor will be required to (i) retain the training skill beyond the initial "train the trainer" training provided by United and (ii) provide training to Contractor's crew personnel at Contractor's own expense.

**PRODUCT LOSS AND PILFERAGE**

United will establish procedures aimed at limiting product loss. At a minimum, it is required that Contractor's Flight Attendants record opening and closing inventories of each product to be sold onboard, accounting for all sales and complimentary items distributed.

Seals may be required to prevent tampering with product inventories and to deter pilferage. United will monitor all inventories and reserves the right to charge Contractor for identified loss due to Contractor's negligence (including breakage and other damage) and pilferage on a cost (non mark-up) basis determined monthly, for any amounts in excess of the monthly product loss allowance (as hereinafter detailed). Any discrepancies in inventories, seal numbers recorded, or excessive complimentary activity for any product sold must be reported at the hub for use in pilferage investigations by United. Contractor's failure to provide documentation as reasonably requested by United or its representatives will result in Contractor being charged for pilferage as reasonably determined by United on a cost basis. United reserves the right to set off the excess value of the loss and/or pilferage caused by Contractor on a cost (non mark-up) basis if in excess of the monthly loss allowance, by taking a credit of such excess loss and/or pilferage pursuant to the procedures set forth in <u>Section 11.13</u> of the Agreement. All reasonable product loss and pilferage procedures established by United must be adhered to by Contractor.

The "monthly product loss allowance" referred to above shall be an amount equal to [\*\*\*] of the value of all beverage or food or other product markets on Contractor's United Express flights, on a monthly basis. All loss allowance procedures established by United, and reasonably agreed to be Contractor, must be adhered to by Contractor.

------

United may, at any time during normal operating hours inspect, monitor, or audit Contractor's administration of the Inflight Product Sales Program described in this Appendix or in other policies and procedures, in order to verify that Contractor is in compliance, in all material respects, with United's requirements for the Inflight Product Sales Program. Contractor will work with United to ensure reasonably appropriate controls exist designed to comply with United's requirements and will ensure corrective actions are in place as necessary.

**LIQUOR, BEER AND WINE PROGRAM**

The Alcoholic Beverage Products offering will be determined by United and provided for by United in the liquor kit supplied to each aircraft. Except as prohibited by law or otherwise agreed by United and Contractor due to the various applicable liquor license laws and regulations, the Alcoholic Beverage Products will be purchased by United prior to being placed onboard Contractor's aircraft and sold onboard all United Express flights designated by United.

Once onboard Contractor's aircraft, liquor drawers, bags or other liquor containment mechanisms used by Contractor, as determined by Contractor, are considered a part of ship's equipment and will be used for the distribution of United's inflight products.

Contractor shall not serve any Alcoholic Beverage Product(s) on the ground without United's consent. Contractor will obtain and maintain, at United's cost and expense, the necessary liquor licenses in the states where they board and/or unload any Alcoholic Beverage Product. Unless otherwise agreed by the parties, Contractor will not board or unload any Alcoholic Beverage Products in Virginia but in the event it is agreed that Contractor will board or unload any Alcoholic Beverage Products in Virginia, the parties shall comply with the procedures for Virginia below.

**Virginia Alcoholic Beverage Handling Procedures**

Contractor will comply with Virginia's liquor purchase procedures. In Virginia, Contractor will board and/or unload only Alcoholic Beverage Products that Contractor owns. To that end, in the event it is agreed by the parties that Contractor will board and/or unload any Alcoholic Beverage Products in Virginia, Contractor will purchase such Alcoholic Beverage Products directly. Contractor will timely pay the supplier of such Alcoholic Beverage Products directly for such order(s). Once out of Virginia airspace, Contractor will transfer to United the title to the purchased Alcoholic Beverage Products. United will be responsible for any sales tax attributable to the foregoing title transfer, as well as the costs associated with the acquisition of such liquor.

**Compliance**

United agrees that it shall comply with all applicable federal, state, and local laws, rules and regulations and United, based upon its activities occurring at a given location, shall obtain and maintain all permits, certifications and licenses necessary for the conduct of its operations relating to the purchase, distribution, storage or provision of any Alcoholic Beverage Product by United.

------

**FOOD AND OTHER PRODUCTS**

United reserves the right to introduce other products for sale onboard including food offerings. Food offerings may come in a variety of packaging options and will be integrated into the entire portfolio with regards to specifications and procedures established by United.

Provisioning of product offering will follow United's procedures at distribution points.

**Re: Sixth Amendment (this "Sixth Amendment" or "Amendment") to the Capacity Purchase Agreement**

Dear Wade:

As you are aware, SkyWest Airlines, Inc. ("<u>Contractor</u>") and United Airlines, Inc. ("<u>United</u>"), are each a party to a Capacity Purchase Agreement dated as of May 16, 2013 (as amended by the parties previously, the "<u>CPA</u>"). Capitalized terms not defined herein shall be defined as provided in the CPA.

United and Contractor each desire to amend the CPA as follows, such amendments to be effective as of September 9, 2015 notwithstanding the date of this Sixth Amendment written above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. United and Contractor agree to add [\*\*\*] Embraer 175 aircraft (the "Tranche 2 Aircraft") as Covered Aircraft under the CPA, subject to the terms and conditions applicable to such Tranche 2 Aircraft. In addition, the following shall apply:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Contractor shall provide, deliver, and operate such Tranche 2 Aircraft as part of the Regional Airline Services it provides under the CPA [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. The Tranche 2 Aircraft shall be referenced on Schedule 1, Schedule 1A, and Schedule 2 to the CPA as E175 Covered Aircraft with Aircraft Numbers [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. The Tranche 2 Aircraft shall be inducted into the Regional Airline Services on the schedule set forth in Schedule 1A (subject to such acceleration or other variation as United and Contractor may mutually agree in writing from time to time, each party acting reasonably).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d. The term of the CPA with respect to such Tranche 2 Aircraft shall be for [\*\*\*] each.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e. United shall have the right, but not the obligation, to exercise its option to extend the Tranche 2 Aircraft as established in Section 10.2(c) of the CPA as added in Section 11 below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;f. Contractor shall ensure that the Tranche 2 Aircraft materially conform to United's specifications (defined as Technical Description TD175-Rev.17, December 2011), including, but not limited to, specifications for aircraft configuration, galley, seats,

------

winglets, etc., and that such aircraft are consistent with the specifications and livery applicable to the Covered Aircraft in operation by Contractor for United prior to this Amendment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;g. The Tranche 2 Aircraft shall not be considered Growth Aircraft, as such term is defined in Section 10.4(a) of the CPA.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;h. The following provision of the CPA shall not apply with respect to such Tranche 2 Aircraft if such aircraft are purchased by Contractor: Section 3.3(c).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Section 2.1(d) of the CPA is hereby deleted in its entirety and replaced with the following:

"(d) <u>Spare Aircraft</u>. Notwithstanding anything to the contrary contained in this Section 2.1 but subject to the provisions below in this Section 2.1(d), Contractor shall maintain the number of spare regional jet aircraft equal to the quotient obtained by dividing (x) the sum of the number of Covered Aircraft and the number of all covered aircraft under each other capacity purchase or similar agreement between or among United and Contractor (excluding EMB 120 aircraft), by (y) [\*\*\*], and rounding the quotient to the nearest whole number; provided that a quotient ending in one-half (0.500) shall be rounded down to the nearest whole number. The spare regional jet aircraft shall be constituted from either Covered Aircraft (the "Spare Aircraft") or other covered aircraft (excluding EMB 120 aircraft) under other capacity purchase or similar agreements between United and Contractor (the "Other Spare Aircraft"), or both, in a proportion determined by United. After United has so instructed Contractor as to such proportion (which is not expected to occur until the adoption of an appropriate amendment to the 2003 Agreement in order to give effect to provisions equivalent to this Section 2.1(d)), Contractor shall select the specific hulls that shall constitute the Spare Aircraft and Other Spare Aircraft; provided that if Contractor has not received instruction or direction from United pursuant to the foregoing sentences of this Section 2.1(d) prior to the delivery of the [\*\*\*] Covered Aircraft listed on Schedule 1, then such [\*\*\*] Covered Aircraft shall be a Spare Aircraft, and if Contractor has not received instruction or direction from United pursuant to the foregoing sentences of this Section 2.1(d) prior to the delivery of the [\*\*\*] Covered Aircraft listed on Schedule 1, then such [\*\*\*] Covered Aircraft shall be a Spare Aircraft. Contractor shall be entitled to use the Spare Aircraft in Contractor's reasonable discretion to replace another regional jet aircraft in the operation of a flight scheduled in the Final Monthly Schedule. In addition, subject to applicable Reasonable Operating Constraints and Conditions, Contractor shall use such Spare Aircraft to operate flights as directed by United (unless such Spare Aircraft was, prior to such direction by United, already scheduled as contemplated by the immediately preceding sentence), including flights originally scheduled to be operated by United or other United service providers."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Section 3.3(d) to the CPA is hereby restated and replaced in its entirety by the following:

[\*\*\*]

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. Section 3.6(c)(iii) of the CPA is hereby deleted in its entirety and replaced with the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. Section 4.1(b) of the Agreement is hereby amended to add the following language at the end of such subsection:

[\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. Section 4.19(a)(i) of the CPA is hereby deleted in its entirety and replaced with the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) The term " <u>Environmental Laws</u> " means all applicable federal, state, local and foreign laws and regulations, guidance documents and policy statements of the Centers for Disease Control, the Occupational Health and Safety Administration, the Department of Transportation, and the Federal Aviation Administration, as well as any airport rules or any other applicable regulations, policies, or lease requirements relating to the prevention of pollution, protection of the environment or occupational health and safety, or remediation of environmental contamination, including, without limitation, laws, regulations and rules relating to emissions to the air, discharges to surface and subsurface soil and waters, regulation of potable or drinking water, the use, storage, release, disposal, transport or handling of Hazardous Materials, protection of endangered species, and aircraft noise, vibration, exhaust and over flight."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. Section 4.21 of the CPA is hereby amended by adding a new subarticle (d), as follows:

"(d) At United's direction, and to the extent permitted by applicable federal law and regulations, mainline ground support equipment ("GSE") and GSE processes shall be used in connection with Contractor's performance of Regional Airline Services; provided that such GSE and GSE processes shall be modified to be compatible with the Covered Aircraft if necessary, such determination to be made by United."

Contractor hereby agrees to operate additional Scheduled Flights originating from LAX to beyond stations such as but not limited to the following: AUS, BOI, BJX, COS, DFW, LAS, MSP, PHX, SAN, SAT, SEA, SFO, SLC, YVR. United estimates that these routes will be served by no more than [\*\*\*] Covered Aircraft, and as a result thereof, will not be subject to the provisions set forth in Section 3.3(f) of the CPA.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. Section 4.8 of the CPA is hereby deleted in its entirety and replaced with the following:

"4.8 <u>Emergency Response</u>.

In the event of an accident or incident involving a Covered Aircraft or Scheduled Flight, United will manage the Humanitarian Response Efforts on behalf of Contractor with full cooperation from Contractor; *provided* that, in all events, Contractor shall manage in coordination with United the initial emergency response and on scene investigation. For the purposes hereof, the term "Humanitarian Response Efforts" shall include United's activation of its Emergency Operations Center and the Telephone Enquiry Center and United's deployment of the members of its Special Assistance Team to the site of the accident or incident to assist survivors and families. Contractor shall be liable for and will indemnify, defend and hold harmless United, United's parent, their respective subsidiaries and their respective directors, officers, employees and agents from and against any and all claims, demands, damages, liabilities, suits, judgments, actions, causes of action, losses, fines, penalties, costs and expenses, including but not limited to, reasonable attorneys' fees, costs and expenses in connection therewith and expenses of investigation and litigation thereof, which may be suffered by, accrued against, charged to or recoverable from United, United's parent, their respective subsidiaries or their respective directors, officers, employees or agents arising out of, connected with, or attributable to any act, error, omission, operation, performance or failure of performance of United, regardless of any negligence whether it be active, passive or otherwise on the part of United (but excluding the gross negligence or willful misconduct of United and its subsidiaries or its directors, officers, agents or employees) related to United's provision of post-accident or post-incident Humanitarian Response Efforts as contemplated in this Section 4.8. The provisions of the foregoing indemnification obligation shall survive the termination of this Agreement for a period of seven years."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. Section 7.3 of the CPA is hereby deleted in its entirety and replaced with the following:

"7.3 <u>Indemnification Claims</u>.

A party (the "<u>Indemnified Party</u>") entitled to indemnification from another party under the terms of this Agreement (the "<u>Indemnifying Party</u>") shall provide the Indemnifying Party with prompt written notice (an "<u>Indemnity Notice</u>") of any third party claim or other claim which the Indemnified Party believes gives rise to a claim for indemnity against the Indemnifying Party hereunder. Notwithstanding the foregoing, the failure of an Indemnified Party to promptly provide an Indemnity Notice shall not constitute a waiver by the Indemnified Party to any right to indemnification or otherwise relieve such Indemnifying Party from any liability hereunder unless and only to the extent that the Indemnifying Party is materially prejudiced as a result thereof, and in any event shall not relieve such Indemnifying Party from any liability which it may have otherwise than on account of this <u>Article VII</u>. With respect to third party claims, the Indemnifying Party shall be entitled, if it accepts financial responsibility for the third party claim, to control the defense of or to settle any such third party claim at its own expense and by its own counsel; *provided* that no settlement by the Indemnifying Party of such a claim will be binding on

------

the Indemnified Party for purposes of the indemnification provisions hereof without the prior written consent of such Indemnified Party to such settlement, which consent may not be unreasonably withheld, conditioned or delayed. The Indemnified Party shall provide the Indemnifying Party with such information as the Indemnifying Party shall reasonably request to defend any such third party claim and shall otherwise cooperate with the Indemnifying Party in the defense of any such third party claim. Except as set forth in this <u>Section 7.3</u>, no settlement or other compromise or consent to a judgment by the Indemnified Party with respect to a third party claim as to which the Indemnifying Party is asserted to have an indemnity obligation hereunder will be binding on the Indemnifying Party for purposes of the indemnification provisions hereof without the prior written consent of such Indemnifying Party to such settlement, which consent may not be unreasonably withheld or delayed, it being agreed however that it shall be reasonable for the Indemnifying Party to withhold or delay its consent if the Indemnifying Party reasonably asserts that the claim is not fully covered by the indemnity provided hereunder, and the entering into of any settlement or compromise or the consent to any judgment in violation of the foregoing shall constitute a waiver by the Indemnified Party of its right to indemnity hereunder to the extent the Indemnifying Party was prejudiced thereby. Any Indemnifying Party shall be subrogated to the rights of the Indemnified Party to the extent that the Indemnifying Party pays for any loss, damage or expense suffered by the Indemnified Party hereunder. If the Indemnifying Party does not accept financial responsibility for the third party claim or fails to defend against the third party claim that is the subject of an Indemnity Notice within [\*\*\*] of receiving such notice (or sooner if the nature of the third party claim so requires), or otherwise contests its obligation to indemnify the Indemnified Party in connection therewith, the Indemnified Party may, upon providing written notice to the Indemnifying Party, pay, compromise or defend such third party claim without the prior consent of the (otherwise) Indemnifying Party. In the latter event, the Indemnified Party, by proceeding to defend itself or settle the matter, does not waive any of its rights hereunder to later seek reimbursement from the Indemnifying Party. With respect to all other claims, the Indemnifying Party shall promptly make payment of such claim upon receipt of reasonably sufficient evidence supporting such claim; *provided*, that if the Indemnifying Party in good faith disputes all or part of its obligation to indemnify the Indemnified Party hereunder or the amount involved, the senior management of each party shall meet to discuss and attempt to resolve such dispute between the parties and, if such dispute is not resolved within [\*\*\*] of such claim being made, then the parties may pursue other remedies."

If a third appraiser is appointed, as referenced in either clause (x) or clause (y) above, and the difference between the determination which is farther from the middle determination and the middle determination is more than [\*\*\*] of the difference between the middle determination and the other of the three determinations, then such farther determination shall be excluded, the remaining two determinations shall be averaged and such average shall be final and binding upon Contractor and United. If none of the three determinations is excluded under the provision described in the immediately preceding sentence, then the three determinations shall be averaged and the resulting amount shall be final and binding upon Contractor and United. All determinations made as provided in this <u>Section 11.16</u> shall be binding upon Contractor and United. All such appraisal costs will be shared equally between Contractor and United."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11. Condition to Effectiveness

**Re: Ninth Amendment (this "Ninth Amendment" or "Amendment") to the Capacity Purchase Agreement**

Ladies and Gentlemen:

As you are aware, SkyWest Airlines, Inc. ("<u>Contractor</u>") and United Airlines, Inc. ("<u>United</u>" and, together, the "<u>Parties</u>"), are each a party to a Capacity Purchase Agreement dated as of May 16, 2013 (as amended from time to time (including, where the context requires, by this Amendment), the "<u>CPA</u>"). Capitalized terms not defined herein shall be defined as provided in the CPA.

SECTION 1. <u>Addition of Covered Aircraft</u>. United and Contractor agree to add [\*\*\*] Embraer 175LL aircraft (the "<u>Tranche 4 Aircraft</u>") as Covered Aircraft under the CPA, subject to the terms and conditions applicable to such Tranche 4 Aircraft. In addition, the following shall apply:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Contractor shall operate such Tranche 4 Aircraft as part of the Regional Airline Services it provides under the CPA, it being understood that, among other things, by operation of <u>Section 2.1(d)</u> of the CPA, the addition of the Tranche 4 Aircraft shall result in the number of Spare Aircraft increasing by [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. United (or an affiliate of United selected in United's sole discretion) shall lease to Contractor each of the Tranche 4 Aircraft pursuant to an aircraft lease agreement in form and substance mutually agreeable to the parties (and such affiliate, if applicable) and as more fully described in Attachment 4 hereto (each, a " <u>Tranche 4 Covered Aircraft Lease</u> "). With respect to each of the Tranche 4 Aircraft, United and Contractor shall use commercially reasonable efforts to ensure that each such Tranche 4 Covered Aircraft Lease is executed and delivered no later than [\*\*\*] prior to the Scheduled In-Service Date for such aircraft. Notwithstanding anything else contained in the CPA or this Amendment to the contrary, if and when a Tranche 4 Covered Aircraft Lease terminates in accordance with its terms, then the aircraft subject to such lease shall no longer constitute a Covered Aircraft from and after the effective date on which the term of such Tranche 4 Covered Aircraft Lease ends, regardless of whether the event giving rise to such lease termination also constitutes an independent termination or withdrawal event under the CPA. Any withdrawal occurring upon such a termination of a Tranche 4 Covered Aircraft Lease shall be separate and distinct from, and shall not limit or supersede, any other withdrawal rights of United contained in the CPA (as amended by this Amendment).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. United (or an affiliate of United selected in United's sole discretion) shall lease to Contractor [\*\*\*] General Electric CF34-8E5 engines to be used as spare engines by Contractor pursuant to an engine lease agreement in form and substance mutually agreeable to the parties (and such affiliate, if applicable) and as more fully described in Attachment

------

4 hereto (each, a "<u>Tranche 4 Spare Engine Lease</u>"); *provided* that, unless otherwise specified in the Tranche 4 Spare Engine Lease, such spare engines shall only be operated on the Tranche 4 Aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d. The Tranche 4 Aircraft shall be referenced on <u>Schedule 1</u>, <u>Schedule 1A</u>, and <u>Schedule 2</u> to the CPA as E175 Covered Aircraft with Aircraft Numbers [\*\*\*] respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e. The Tranche 4 Aircraft shall be inducted into the Regional Airline Services based on the schedule set forth in <u>Schedule 1A</u> applicable to such aircraft (subject to such acceleration or other variation as United and Contractor may mutually agree in writing from time to time).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;f. The Tranche 4 Aircraft shall not be considered Growth Aircraft, as such term is defined in <u>Section 10.4(a)</u> of the CPA.

Effective from and after January 1, 2020, United and Contractor shall adhere to the provisions set forth in Attachment 5 to the Ninth Amendment (as such provisions, collectively, the "<u>Incentive Program</u>") under which Contractor's monthly compensation under this Agreement shall be adjusted (the aggregate monthly adjustment for any given calendar month, the "<u>Monthly Incentive Adjustment</u>") as more fully set forth in the Incentive Program (it being understood that, if the Monthly Incentive Adjustment under the Incentive Program would result in a payment to Contractor, then Contractor's monthly compensation payable under this Agreement pursuant to <u>Section 3.6</u> shall be increased by the Monthly Incentive Adjustment, and, if the Monthly Incentive Adjustment under the Incentive Program would result in a credit to United, then Contractor's monthly compensation payable under this Agreement pursuant to <u>Section 3.6</u> shall be reduced by the Monthly Incentive Adjustment).

Wacker Drive, Chicago, Illinois 60606 ("**United**") and SKYWEST AIRLINES, INC., a Utah corporation, having its principal mailing address at 444 South River Road, St. George, Utah 84790 ("**Contractor**", and together with United, the "**parties**"). All terms and provisions set forth in this Amendment are effective as of the Amendment Effective Date.

**WHEREAS**, the parties previously entered into that certain Capacity Purchase Agreement dated as of May 16, 2013 (such agreement, as amended from time to time, the "**Agreement**" or the "**CPA**");

**WHEREAS**, the parties wish to add [\*\*\*] Embraer 175LL aircraft (the "**Tranche 6 Aircraft**") as Covered Aircraft under the Agreement, subject to the terms and conditions of the Agreement (as amended by this Amendment) applicable to such Tranche 6 Aircraft, which Tranche 6 Aircraft are more specifically described with numbers [\*\*\*] of Schedule 1 to the Agreement (as such schedule is revised by this Amendment); and

**WHEREAS**, Contractor and United further wish to amend certain other provisions of the Agreement.

**NOW THEREFORE**, in consideration of the foregoing and other good and valuable consideration, the receipt, validity and sufficiency of which are hereby acknowledged, the parties hereby agree to amend the Agreement as follows:

**SECTION 1.** **Defined Terms**. Capitalized terms used in this Amendment that are defined in the Agreement and are not otherwise defined in this Amendment shall have the meanings given to them in the Agreement.

**SECTION 2**.**Addition of Tranche 6 Aircraft**. United and Contractor agree to add each Tranche 6 Aircraft as Covered Aircraft under the CPA, subject to the terms and conditions applicable to such Tranche 6 Aircraft. In addition, the following shall apply:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Contractor shall operate such Tranche 6 Aircraft as part of the Regional Airline Services it provides under the CPA, it being understood that, among other things, by operation of <u>Section 2.1(d)</u> of the CPA, the addition of the Tranche 6 Aircraft shall result in the number of Spare Aircraft increasing by [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. United (or an affiliate of United selected in United's sole discretion) shall lease to Contractor each of the Tranche 6 Aircraft pursuant to a Tranche 6 Covered Aircraft Lease. With respect to each of the Tranche 6 Aircraft, United and Contractor shall use commercially reasonable efforts to ensure that each such Tranche 6 Covered Aircraft Lease is executed and delivered no later than [\*\*\*] prior to the Scheduled In-Service Date for such aircraft as set forth in <u>Schedule 1B</u>. Notwithstanding anything else contained in the CPA or this Amendment to the contrary, if and when a Tranche 6 Covered Aircraft Lease terminates in accordance with its terms, then the aircraft subject to such lease shall no longer constitute a Covered Aircraft from and after the effective date on which the term of such Tranche 6 Covered Aircraft Lease ends, regardless of whether the event giving rise to such lease termination also constitutes an independent termination or withdrawal event under the CPA. Any withdrawal occurring upon such a termination of a Tranche 6 Covered Aircraft Lease shall be separate and distinct from, and shall not limit or supersede, any other withdrawal rights of United contained in the CPA (as amended by this Amendment).

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.

Nothing in this ***Section 3.09*** is meant to limit or prevent Contractor from using the Substitute Heavy Maintenance Aircraft to perform flight services for a Third Party carrier when not being utilized for Regional Airline Services during a Heavy Maintenance Substitute Period. The terms and conditions of this Agreement (including but not limited to audit and inspection rights (including the audit and inspection rights set forth in ***Schedule 4***), governmental regulations, aircraft condition standards, compensation, insurance and maintenance) applicable to the CRJ Covered Aircraft being substituted shall apply in full force and effect with respect to any such Substitute Heavy Maintenance Aircraft, and such Substitute Heavy Maintenance Aircraft shall be deemed a Covered Aircraft, in each case, solely when such Substitute Heavy Maintenance Aircraft is providing Regional Airline Services; *provided*, *however*, [\*\*\*]. Upon the end of the applicable Heavy Maintenance Substitute Period for a CRJ Covered Aircraft, the applicable Substitute Heavy Maintenance Aircraft shall cease providing Regional Airline Services. If a Substitute Heavy Maintenance Aircraft is substituted for a CRJ Covered Aircraft as provided in this ***Section 3.09(b)***, then (A) [\*\*\*] In the event that the induction of any CRJ Covered Aircraft into Heavy Maintenance would cause the aggregate number of all CRJ Covered Aircraft then in Heavy Maintenance to exceed [\*\*\*] Covered Aircraft, then at least [\*\*\*] prior to the induction into Heavy Maintenance of such excess CRJ Covered Aircraft, Contractor shall deliver Notice thereof to American [\*\*\*]. For the avoidance of doubt, a Substitute Heavy Maintenance Aircraft provided pursuant to this ***Section 3.09*** shall not be deemed a Substitute Aircraft pursuant to ***Section 3.08*** of this Agreement.

**Section 14.07** **Data Security**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)**Safeguards**. Where Contractor stores or processes American Data, Contractor shall and shall cause its Contractor Agents to establish and maintain a secure environment for all American Data and any hardware and software (including servers, network and data components) to be provided or used by Contractor or its Contractor Agents to store or process American Data.

***Execution Version***

such out-of-pocket costs and expenses, so that American may determine whether to implement the procedures. In the event that American determines that it will require Contractor to comply with such event reporting procedures, American shall be responsible for any reasonable and documented out-of-pocket costs and expenses actually incurred by Contractor relating to event reporting procedures as Pass Through Costs payable by American pursuant to ***Schedule 3***. Failure by Contractor to comply with Security Best Practices in fulfilling their obligations hereunder shall constitute a breach of this Agreement.

If Contractor breaches this ***Section 14.07***, then American shall have the right to require Contractor to reimburse American for actual out-of-pocket costs and expenses of printing and mailing notification letters required by any law, rule or regulation of a Governmental Authority incurred by American or its Affiliates due to such breach and any credit monitoring services offered by American or any Affiliate in relation to the breach.

Except for the Permitted Uses, Contractor may not edit, modify, create derivatives, combinations or compilations of, combine, associate, synthesize, reverse engineer, reproduce, display, distribute, disclose, or otherwise process American Data. In addition, for clarity, Contractor must not directly or indirectly engage in any of the following activities: (x) use or disclosure of American Data in a way that may adversely affect American, including any use by or disclosure to other airlines, or (y) any kind of commercialization, marketing, advertising, licensing or resale that is based on American Data (*e.g.*, targeted advertising to consumers based on the American Marks).

With respect to Flight Status Data, in no event may Contractor disclose all or individual parts of the Flight Status Data, except as otherwise permitted herein.

Subject to the remaining provisions of this ***Section 14.08***, Contractor shall securely delete all American Data held in its systems and cause all Contractor Agents to securely delete all American Data held in their respective systems within [\*\*\*] after the expiration or effective date of termination of this Agreement. Contractor may retain backup copies of American Data that were captured as part of Contractor's normal course of business if it would be commercially or technologically impractical to delete such data in accordance with this ***Section 14.08(d)*** or for evidentiary purposes on the condition that Contractor continues to comply with the confidentiality, compliance, data security and privacy provisions of this Agreement for as long as such backup copies exist. Contractor represents and warrants that it has in place and follows a business process to delete backups of its customers' data that are no longer needed. Contractor may retain that portion of American Data that it must retain pursuant to applicable law (including Data Law) on the condition that Contractor continues to comply with the confidentiality, compliance, data security and privacy provisions of this Agreement, including but not limited to ***Exhibit D***, for as long as it retains such data and deletes such American Data as soon as Contractor is no longer subject to such legal requirement. Contractor shall use commercially reasonable efforts to anonymize and de-identify American Data retained by it after the expiration or termination of this Agreement pursuant to this ***Section 14.08(d)***.

**Section 14.09** **Cooperation with Respect to Reporting**. American, on the one hand, and Contractor, on the other hand, shall use their commercially reasonable efforts to cooperate with the other in providing necessary data, to the extent in the possession of the other, required by the other to meet any reporting requirements to, or otherwise necessary in connection with any filing with or provision of information to be made to, any regulatory agency, stock exchange, or other Governmental Authority by the other.

**Section 14.10** **Right of Set-off**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)**General Right of Set-off**. If Contractor shall be in default of any of its obligations under this Agreement, then American shall be entitled to set-off against any undisputed payment

***Execution Version***

owed by American to Contractor hereunder any undisputed amount owed by Contractor to American hereunder; *provided*, that contemporaneously with any such set-off, American shall give Notice of such action to Contractor; *provided*, *further*, that the failure to give such Notice shall not affect the validity of the set-off. If American shall be in default of any of its obligations under this Agreement, then Contractor shall be entitled to set-off against any undisputed payment owed by Contractor to American hereunder any undisputed amount owed by American to Contractor hereunder; *provided*, that contemporaneously with any such set-off, Contractor shall give Notice of such action to American; *provided*, *further*, that the failure to give such Notice shall not affect the validity of the set-off. It is specifically agreed that for purposes of the set-off by American, on the one hand as a non-defaulting Party, or Contractor, on the other hand as a non-defaulting Party, mutuality shall be deemed to exist between American and Contractor. Upon completion of any such set-off, the obligation of the non-defaulting Party to the defaulting Party shall be extinguished to the extent of the amount so set-off. This set-off provision shall be without prejudice and in addition to any right of set-off, combination of accounts, lien or other right to which American, on the one hand as the non-defaulting Party, or Contractor, on the other hand as the non-defaulting Party, is at any time otherwise entitled (either by operation of law, contract or otherwise).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)**Late Adjustment Charge Right of Set-Off**. Without limiting the provisions of ***Section 14.10(a)*** above, pursuant to ***Section 6.08***, it is specifically agreed that for purposes of American's right of set-off with respect to any Late Adjustment Charge, American and Contractor shall be deemed to have obligations to one another under this Agreement. In the event any Late Adjustment Charge is fully set-off by American against amounts owed by Contractor, then the obligation of Contractor to American shall be deemed extinguished to the extent of the amount so set-off. This set-off provision shall be without prejudice and in addition to any right of set-off, combination of accounts, lien or other right to which American is at any time otherwise entitled (either by operation of law, contract or otherwise).

**Section 14.11** **Counterparts**. This Agreement may be executed in two (2) or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. This Agreement may be executed by facsimile signature or portable document format (pdf).

**Section 14.12** **Severability**.

**WHEREAS**, Contractor and Alaska are each willing to perform in the manner and upon the conditions and terms hereinafter set forth; and

**WHEREAS**, the obligations of Alaska hereunder shall be guaranteed by Parent Guarantor pursuant to the Parent Guaranty.

**NOW, THEREFORE**, in consideration of the foregoing premises and the mutual covenants and obligations hereinafter contained, the parties agree as follows:

**ARTICLE I**

**DEFINITIONS**

Capitalized terms used in this Agreement (including, unless otherwise defined therein, in the Schedules, Appendices and Exhibits to this Agreement) shall have the meanings set forth in <u>Exhibit A</u> hereto.

**ARTICLE II**

**CAPACITY PURCHASE, SCHEDULES AND FARES**

Section 2.01 *Capacity Purchase*. Alaska agrees to purchase the capacity of each Covered Aircraft and each Transition Aircraft (and any Spare Aircraft used in lieu of any Covered Aircraft or Transition Aircraft in accordance with the terms of this Agreement), for the period beginning on (A) as to the Covered Aircraft, the Operation Date for such Covered Aircraft and ending on the earlier of (i) the sublease or lease expiration date, as applicable, for such aircraft on <u>Schedule 1</u> and (ii) the date on which such aircraft is withdrawn from this Agreement pursuant to the terms hereof, as such date may be extended, shortened or otherwise modified pursuant to the terms of this Agreement, and (B) as to the Transition Aircraft, during the Transition Period, all under the terms and conditions set forth herein and for the consideration described in <u>Article III</u>. Subject to the terms and conditions of this Agreement, Contractor shall provide all of the capacity of the Covered Aircraft and each Transition Aircraft (and any Spare Aircraft used in lieu of any Covered Aircraft or Transition Aircraft in accordance with the terms of this Agreement) solely to Alaska and use such aircraft solely to operate Scheduled Flights. For purposes of this Agreement, as the context requires, during the Transition Period the Transition Aircraft shall be deemed Covered Aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)*Fares, Rules and Seat Inventory*.

Alaska shall also be entitled, in its sole discretion and at any time prior to takeoff, to direct Contractor to delay or cancel a Scheduled Flight, including without limitation for delays and cancellations that are ATC or weather related, and Contractor shall take all necessary action to give effect to any such direction. Not later than [\*\*\*] days prior to the beginning of each calendar month, Alaska shall provide Contractor with a planned flight schedule for the Covered Aircraft for such month, subject to Reasonable Operating Constraints and Conditions (the "<u>Proposed Schedule</u>"). On the first Friday following delivery of the Proposed Schedule, appointed personnel of Contractor and Alaska shall meet to review the Proposed Schedule. At such meeting, Alaska shall review and consider any changes to the Proposed Schedule suggested by Contractor. Not later than [\*\*\*] days prior to the beginning of the calendar month for the applicable Proposed Schedule, Alaska will deliver to Contractor the Final Monthly Schedule.

Notwithstanding anything to the contrary contained in this <u>Section 2.01</u>, Contractor shall be entitled to use the Covered Aircraft and each Transition Aircraft (and any Spare Aircraft used in lieu of any Covered Aircraft or Transition Aircraft in accordance with the terms of this Agreement) (i) for the purpose of flying maintenance flights as required to facilitate the proper maintenance of such aircraft and (ii) for a reasonable number of ferry flights to accommodate Scheduled Flights (all such flights described in clauses (i) and (ii) referred to as "<u>Maintenance Flights</u>"). Contractor shall timely notify Alaska upon the occurrence of any non-routine Maintenance Flights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)*Spare Aircraft*. Subject to Reasonable Operating Constraints and Conditions, Contractor shall maintain [\*\*\*] Spare Aircraft to operate Scheduled Flights as contemplated in <u>Exhibit F</u> (i.e., a "maintenance spare"). Contractor shall use commercially reasonable efforts to use a neutrally painted Spare Aircraft for such Scheduled Flights. [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)*Transition Period*. During the Transition Period, (i) Contractor will provide the Transition Aircraft from the Transition Date through the end of the Transition Period, (ii) each Transition Aircraft shall operate Scheduled Flights, subject to Reasonable Operating Constraints and Conditions, and

Contractor agrees that it shall cooperate with all reasonable requests by Alaska so as to permit Alaska to account for and receive all Flight Related Revenue. Contractor's obligations to remit funds under this <u>Section 2.02</u> shall only apply to the extent Contractor actually receives Flight Related Revenue.

Section 2.03 *Pass Travel*. All pass travel and other non-revenue travel on any Scheduled Flight or flights operated by Alaska or its Affiliates shall be administered in a manner consistent with the Interline Agreement described in <u>Exhibit C</u>.

------

Section 2.04 *Additional Aircraft*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Unless this Agreement has been terminated by Alaska pursuant to <u>Sections 7.02</u> or <u>7.03</u> or by Contractor pursuant to <u>Section 7.04</u>, at any time during the period beginning on the Effective Date and ending on the [\*\*\*] anniversary of the Effective Date, if Alaska decides to solicit bids for the operation of additional regional aircraft to be used in Alaska's regional airline service (such additional aircraft, "<u>Additional Aircraft</u>"), then, at least [\*\*\*] months prior to the entry of such Additional Aircraft into Alaska's regional airline service or as soon as possible following such decision to solicit bids, whichever is less, Alaska agrees to give Contractor written notice of its intention to use such Additional Aircraft, and to offer Contractor the opportunity to bid on such Additional Aircraft. If, at the time the foregoing notice is given and at the time of any award referenced below, (A) Contractor has consistently satisfied in all material respects the standards of care and service described in <u>Sections 4.04</u> and <u>4.05</u> in connection with its obligations under this Agreement and otherwise complied in all material respects with the terms of this Agreement, except to the extent such non-compliance directly results from material circumstances outside of Contractor's reasonable control, and (B) Alaska and Contractor, each acting reasonably, agree on economic terms and conditions relating to such Additional Aircraft, then Contractor shall be awarded such Additional Aircraft; *provided,* that if Alaska has received bona fide bids from third parties, then Alaska shall be deemed to be acting reasonably if it refuses to agree with Contractor to terms and conditions that are less beneficial to Alaska than the terms and conditions contained in the bona fide bid of any third party to which Alaska in good faith would intend to award the Additional Aircraft, after providing Contractor with a counteroffer signed by an authorized officer of Alaska setting forth the material terms matching such third party's bid (specifically including all terms material and beneficial to Contractor) and providing Contractor not less than [\*\*\*] days to review and match such bid. If Contractor elects to match any such bid, then Alaska shall award all Additional Aircraft covered by such bid to Contractor on the terms and conditions set forth in the counteroffer. If Contractor is awarded any Additional Aircraft, then within [\*\*\*] days after such award Contractor and Alaska shall use their respective commercially reasonable efforts to enter into a separate capacity purchase agreement or amend this Agreement for such Additional Aircraft reflecting the agreed-upon terms and conditions and otherwise being in a form substantially similar to the terms and conditions set forth herein; *provided,* that if Contractor and Alaska do not enter into such separate capacity purchase agreement or amend an existing capacity purchase agreement within such [\*\*\*] period with respect to any Additional Aircraft, unless due to Alaska's bad faith, then Alaska shall have the option to cancel the award of such Additional Aircraft to Contractor and thereafter to award such Additional Aircraft to any other party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)For purposes of this <u>Section 2.04</u>, (x) the term "<u>Additional Aircraft</u>" shall not include (I) any aircraft that enters Alaska's regional airline service as a result of any merger, combination or similar transaction (other than an acquisition) of, with or by Alaska or its Affiliates, (II) any aircraft that enters Alaska's regional airline service as a result of the acquisition by Alaska or its Affiliates of all or substantially all of the assets of another air carrier, or (III) any turbo prop aircraft operated for the benefit of Alaska by Alaska or any Affiliate of Alaska; and (y) the phrase "regional aircraft used in Alaska's regional airline service" (and similar phrases) shall include only regional jet aircraft (or any successor branded regional jet aircraft) bearing the service marks or livery of Alaska or any of its Affiliates (each an "<u>Alaska-Branded</u>" aircraft) operating from and to any point within the continental United States.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Alaska agrees that if Alaska or its Affiliates decide to use additional Alaska- Branded regional aircraft (other than regional aircraft described in clause (x) of paragraph (b) of this <u>Section 2.04</u>) in Alaska's regional airline service, then Alaska shall solicit bids for the operation of such aircraft.

------

Section 2.05 *Covered Aircraft*. Upon termination of the Covered Aircraft Sublease, such aircraft shall cease to be a Covered Aircraft for purposes of this Agreement. In the event the Covered Aircraft Sublease is terminated due to actions not arising out of the actions of Contractor, [\*\*\*] Alaska shall reimburse Contractor for all costs and expenses, if any, associated with the maintenance costs incurred with the return of the Covered Aircraft and the wind-down of pilots, flight attendants and maintenance personnel assigned to operate or support Scheduled Flights at the time of termination. Contractor agrees to use commercially reasonable efforts to mitigate and minimize such costs; provided, in no event shall the wind-down costs associated with such pilots, flight attendants and maintenance personnel exceed [\*\*\*] per employee. Alaska shall make payment of the foregoing costs within [\*\*\*] Business Days after receipt of an invoice reflecting the costs.

Alaska has set as operational performance targets the following: [\*\*\*] The foregoing are targets only, and Contractor's failure to meet such targets shall not result in financial penalties (except as provided in <u>Paragraph E</u> of <u>Schedule 2</u>) or give rise to any breach, failure to perform or termination right by Alaska hereunder.

Section 4.11 *Use of Alaska Marks*.

Alaska further covenants and agrees not to accelerate, or cause any of its Affiliates to accelerate, the "Head Lease Expiration Date" as provided on <u>Schedule 1</u> hereto with respect to any aircraft being operated by Contractor pursuant to this Agreement as of the time of determination without the prior written consent of Contractor.

Section 4.15 *Use of Covered Aircraft*. Contractor agrees that, except as otherwise directed or approved in writing by Alaska in its sole discretion, the Covered Aircraft may be used only to provide Regional Airline Services.

During the Term of the Agreement, Alaska shall place its designator code, "AS", on all Scheduled Flights operated by Contractor. Alaska may suspend the display of its code on flights operated by Contractor if Contractor is in breach of any of its safety-related obligations, or material breach of any of its operational obligations, under the Agreement during the period that such breach continues. All Contractor operated flights that display the AS code are referred to herein as "AS\* Flights".

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. *Contractor's display of AS code*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) All AS\* Flights will be included in the schedule, availability and fare displays of all computerized reservations systems in which Alaska and Contractor participate, the Official Airline Guide (to the extent agreed upon) and Alaska's and Contractor's internal reservation systems, under the AS code, to the extent possible. Alaska and Contractor will take the appropriate measures necessary to ensure the display of the schedules of all AS\* Flights in accordance with the preceding sentence.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Alaska and Contractor will disclose and identify the AS\* Flights to the public as actually being a flight of and operated by Contractor, in at least the following ways:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)a symbol will be used in timetables and computer reservation systems indicating that AS\* Flights are actually operated by Contractor;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)to the extent reasonable, messages on airport flight information displays will identify Contractor as the operator of flights shown as AS\* Flights;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)Alaska and Contractor advertising concerning AS\* Flights and Alaska and Contractor reservationists will disclose Contractor as the operator of each AS\* Flight;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Alaska Airlines' website (www.alaskaair.com) and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.*Terms and Conditions of Carriage*. In all cases the contract of carriage between a passenger and a carrier will be that of the carrier whose code is designated on the ticket. Alaska and Contractor shall each cooperate with the other in the exchange of information necessary to conform each carrier's contract of carriage to reflect service offered by the other carrier. For avoidance of doubt, the carrier whose code is designated on the ticket is the marketing carrier and not the operating carrier.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.*Notification of irregularities in operations*. Contractor shall promptly notify Alaska of all irregularities involving a AS\* Flight which result in any material damage to persons or property as soon as such information is available and shall furnish to Alaska as much detail as

Subject to the terms and conditions of the Agreement, Alaska hereby grants to Contractor a nonexclusive, nontransferable, revocable license to use the AS\* designator code on all of its flights operated as a AS\* Flight.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)*Control of AS\* Flights*. Subject to the terms and conditions of the Agreement, Contractor shall have sole responsibility for and control over, and Alaska shall have no responsibility for, control over or obligations or duties with respect to, each and every aspect of Contractor's operation of AS\* Flights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.*Display of other codes*. During the Term of the Agreement, Alaska shall have the exclusive right to determine which other airlines ("<u>Alliance Airlines</u>"), if any, may place their two letter designator codes on flights operated by Contractor with Covered Aircraft and to enter into agreements with such Alliance Airlines with respect thereto**.** Contractor will cooperate with Alaska and any Alliance Airlines in the formation of a code share relationship between Contractor and the Alliance Airlines and enter into reasonably acceptable agreements and make the necessary governmental filings, as requested by Alaska, with respect thereto.

**EXECUTION VERSION**

**FIRST AMENDMENT TO**

**CAPACITY PURCHASE AGREEMENT**

THIS FIRST AMENDMENT TO CAPACITY PURCHASE AGREEMENT (this "<u>First Amendment</u>") is made and entered into as of October 19, 2013 (the "<u>Effective Date</u>"), by and between Alaska Airlines, Inc., an Alaska corporation ("<u>Alaska</u>"), and SkyWest Airlines, Inc., a Utah corporation ("<u>Contractor</u>").

<u>RECITALS</u>:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A.Alaska and Contractor are parties to that certain Capacity Purchase Agreement, dated as of April 13, 2011 (the "<u>CPA</u>").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B.All capitalized terms used herein, but not otherwise defined herein, shall have the meanings given to such terms in the CPA. It is the intent of the parties that this First Amendment and the subject matter addressed herein is integral to the entirety of the CPA and is not severable therefrom.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C.Contractor and Alaska desire to amend the CPA to provide for the addition of three Covered Aircraft and to make the other changes and agreements as set forth in this First Amendment.

NOW, THEREFORE, in consideration of the promises and covenants set forth herein, and for other valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Alaska and Contractor agree as follows:

1.<u>Schedule 1</u>. <u>Schedule 1</u> to the CPA is hereby amended and restated as set forth in the "<u>First Amended and Restated Schedule 1</u>" attached to this First Amendment, to add [\*\*\*] additional CRJ-700 aircraft as "Covered Aircraft" to the terms of the CPA (the "<u>2013 Aircraft</u>"). Contractor will operate the 2013 Aircraft pursuant to the terms of the CPA. Identification information, and the commencement, operation and sublease expiration dates, for the 2013 Aircraft are set forth in such <u>First Amended and Restated Schedule 1</u>. Except as specifically modified by this First Amendment, the terms and conditions of the CPA shall apply to the 2013 Aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. <u>Rates and Adjustments</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.1<u>Rates</u>. In consideration of the transportation service, facilities and other services to be provided by Contractor under the CPA in respect of the 2013 Aircraft, Alaska will pay Contractor the base and incentive compensation as provided in <u>Schedule 2</u> of the CPA, subject to the terms and conditions of Article III of the CPA; provided that with respect to the 2013 Aircraft, the references in the CPA, and in <u>Schedule 2</u> of the CPA, to "<u>Appendix 1</u> to this <u>Schedule 2</u>" or similar phrases shall be deemed to refer to "<u>Appendix 1(B)</u> to <u>Schedule 2</u>" as attached to this First Amendment (and see further "<u>Appendix</u>"-related amendments below). For avoidance of doubts, the rates with respect to Covered Aircraft (other than the 2013 Aircraft) are as set forth in "<u>Appendix 1(A)</u> to <u>Schedule 2</u>" except (i) with respect to the "Fixed Cost Per Month", which shall be as provided in Section 10 of this First Amendment below [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.2<u>Adjustments for New Regulations</u>. In the event a mandatory regulation is proposed and enacted after the date hereof that materially increases the cost of the operations for the entire regional industry, including, but not limited to the mandatory crew rest changes set forth in 14 CFR 117, the rates

------

for each of the Covered Aircraft (including, without limitation, the 2013 Aircraft) under the CPA as provided for in <u>Schedule 2</u> to the CPA (including <u>Appendix 1(A)</u> and <u>Appendix 1(B)</u> thereto), all as amended, will be amended to reflect the actual and demonstrated cost impact of such changes; provided, however, that with respect to the mandatory crew rest changes set forth in 14 CFR 117, no such adjustment shall exceed [\*\*\*] per block hour. For the avoidance of doubt, the mandatory crew rest changes set forth in 14 CFR 117 have not been implemented by Contractor as of the date hereof. Accordingly, the implementation of such crew rest rules (and related regulations) will result in the application of the terms of this Section 2.2 to the extent of actual and demonstrated cost impact to Contractor.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. <u>Maintenance Contribution Costs</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.1The parties acknowledge that as of the date of this First Amendment, the parties are unable to determine the maintenance contribution costs associated with the 2013 Aircraft. Accordingly, prior to the Operation Date of the each 2013 Aircraft, the parties hereto shall determine the maintenance contribution costs associated with such 2013 Aircraft using a methodology substantially similar to that previously used to determine the maintenance contribution costs for the Covered Aircraft, each acting reasonably, and that such amount shall be set forth on the attached "<u>Appendix 3</u> to <u>Schedule 2</u>" (the "<u>2013 Maintenance Contribution Costs</u>"). If the parties are unable to agree on the maintenance contribution costs for any 2013 Aircraft prior to the Operation Date of such 2013 Aircraft, then, upon written notice, either party may terminate this First Amendment (together with the related sublease if in effect) with respect to the operation of such 2013 Aircraft. In such event, Alaska shall promptly reimburse Contractor for all third-party costs and expenses incurred by Contractor with respect to such terminated 2013 Aircraft prior to such termination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.2Upon determination by the parties of the maintenance contribution costs described in Section 3.1 above, the respective 2013 Maintenance Contribution Costs for the 2013 Aircraft will be included in the Invoiced Amount for the respective month of payment as identified on <u>Appendix 3</u> to <u>Schedule 2</u> and paid as provided in <u>Section 3.05</u> of the CPA. The foregoing payments shall be made to account for the operation of the 2013 Aircraft prior to the Commencement Date.

4.<u>Amendments to Schedule 2 Paragraph D</u>. The current Paragraph D of <u>Schedule 2</u> to the CPA is hereby amended to be renamed Paragraph "D.1." The above <u>Section 3</u> of this First Amendment is hereby added to <u>Schedule 2</u> to the CPA as Paragraph "D.2" and inserted immediately following the newly titled Paragraph D.1.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. <u>Delivery of 2013 Aircraft and Delivery Maintenance Costs</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.1<u>Delivery</u>. The 2013 Aircraft will be delivered to Contractor pursuant to the terms of a Covered Aircraft Sublease substantially in the same form as previously agreed upon by and between Alaska and Contractor. On the Commencement Date, Alaska will deliver to Contractor (or caused to be delivered to Contractor) each 2013 Aircraft in compliance with a U.S. Standard Certificate of Airworthiness.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.2 <u>Pre-Delivery Maintenance</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.2.1Prior to the Commencement Date, each of the 2013 Aircraft will undergo maintenance, service and repair primarily at a maintenance facility of an affiliate of Manufacturer, with such maintenance, service and repair being done in part to provide bridging maintenance associated with inclusion of the 2013 Aircraft into Contractor's maintenance program ("<u>Pre-Delivery Maintenance</u>"). As to the first two 2013 Aircraft to be delivered pursuant to the delivery schedule, Alaska and Contractor

------

have previously agreed on the scope of such Pre-Delivery Maintenance. The parties agree that as to the third 2013 Aircraft to be delivered pursuant to the delivery schedule, the scope of such Pre-Delivery Maintenance will be substantially similar to the Pre-Delivery Maintenance with respect to the initial two 2013 Aircraft, taking into consideration the respective maintenance needs of such aircraft.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.2.2With respect to Pre-Delivery Maintenance for each 2013 Aircraft, Contractor agrees to reimburse Alaska for third-party maintenance expenses incurred by Alaska in an amount not to exceed [\*\*\*] per-2013 Aircraft ("<u>Pre-Delivery Maintenance Costs</u>"). Within [\*\*\*] days following the Commencement Date of each 2013 Aircraft, Alaska will present to Contractor an invoice reflecting the Pre-Delivery Maintenance Costs for such aircraft, such invoice containing reasonable detail of the Pre- Delivery Maintenance performed and the costs associated therewith.

**EXHIBIT F**

**Reasonable Operating Constraints and Conditions**

The reasonable operating constraints and conditions for the operation of Scheduled Flights shall be those imposed by the aircraft type, maintenance requirements (including C-checks and other heavy maintenance requirements), crew training requirements, aircraft rotation requirements, and route authorities, slots and other applicable regulatory restrictions on flight schedules, consistent with reasonably determined standards determined by Contractor and Alaska.

Alaska agrees to work with Contractor to schedule the Covered Aircraft in a manner such that Contractor can comply with Contractor's maintenance obligations as provided in Section 9 of the First Amendment and Section 4 of the Fifth Amendment.

<u>Spare Aircraft</u>

As of the Effective Date of the Eleventh Amendment, [\*\*\*]. Accordingly, Alaska acknowledges that the Final Monthly Schedule for the Covered Aircraft will need to provide for adequate down-time for the maintenance requirements of the Covered Aircraft by pulling down one line of flying for the period of maintenance. For the avoidance of doubt, Spare Aircraft will be operational spare aircraft to be used solely with respect to the Covered Aircraft then operating pursuant to the Final Monthly Schedule and not for the Covered Aircraft then subject to pull- down for maintenance as contemplated in the immediately preceding sentence.

At such time as the number of Aircraft subject to the terms of this Agreement is less then [\*\*\*] (including Spare Aircraft), [\*\*\*] Spare Aircraft and will be operated and scheduled as provided in the Agreement, including as set forth in this Exhibit F. At such time as at least [\*\*\*] Aircraft (including Spare Aircraft) are subject to the terms of this Agreement, the Parties will mutually agree on the number of aircraft designated as Spare Aircraft as necessary to provide adequate coverage based on the fleet size, such Spare Aircraft to be operated and scheduled as provided in the Agreement, including as set forth in this Exhibit F.

<u>Overnight Maintenance</u>.

With respect to the Covered Aircraft other than the EMB Aircraft, such Covered Aircraft shall be scheduled for overnight maintenance in a manner consistent with current practice.

With respect to the EMB Aircraft, for such period as the average age since new of such EMB Aircraft is from [\*\*\*] to [\*\*\*] years, [\*\*\*] of such EMB Aircraft shall be scheduled for overnight maintenance of [\*\*\*] hours in duration in BOI, FAT, TUS or SLC. For periods after the average age since new of such EMB Aircraft is in excess of [\*\*\*] years, [\*\*\*] of such EMB Aircraft shall be scheduled for overnight maintenance of [\*\*\*] hours in duration in BOI, COS, TUS or SLC.

The reasonable operating constraints and conditions for the operation of Scheduled Flights shall be those imposed by the aircraft type, maintenance requirements (including C- checks and other heavy maintenance requirements), crew training requirements, aircraft rotation requirements, and route authorities, slots and other applicable regulatory restrictions on flight schedules, consistent with reasonably determined standards determined by Contractor and Alaska. The Final Monthly Schedule for the Covered Aircraft provide for adequate down-time for the maintenance requirements of the Covered Aircraft by pulling down sufficient line(s) of flying to accommodate such maintenance, as reasonably determined by Contractor and Alaska.

<u>Spare Aircraft</u>. [\*\*\*] Covered Aircraft will be Spare Aircraft and shall be used as operational spare aircraft that may be used to operate Scheduled Flight(s) for any Covered Aircraft that is unable to operate such flight for any reasons. For the avoidance of doubt, Spare Aircraft will be operational spare aircraft to be used solely with respect to the Covered Aircraft then operating pursuant to the Final Monthly Schedule and not for the Covered Aircraft then subject to pull- down for maintenance as contemplated in the immediately preceding sentence. The parties may from time to time increase or decrease the number of the Spare Aircraft, subject to agreement of the parties.

<u>Overnight Maintenance</u>. For such period as the average age since new of the EMB Aircraft is from [\*\*\*] to [\*\*\*] years, [\*\*\*] of such EMB Aircraft shall be scheduled for overnight maintenance of [\*\*\*] hours in duration in BOI, FAT, TUS or SLC. For periods after the average age since new of such EMB Aircraft is in excess of [\*\*\*] years, [\*\*\*] of such EMB Aircraft shall be scheduled for overnight maintenance of [\*\*\*] hours in duration in BOI, COS, TUS or SLC.

<u>Revenue Lines</u>. The Final Monthly Schedule will schedule revenue lines for [\*\*\*] block hours per day per revenue line.

[\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.

If any of the start-up team members are required to attend in any other location than those mutually agreed to therein, Buyer will bear all expenses related to the start-up team, including but not limited to transportation, boarding and lodging of the start-up team in such new location. At [\*\*\*] Buyer shall provide the Embraer pilots which are part of the start-up team with transportation means from/to Buyer operational bases or airport where such pilots will render the Services, so that the pilots can report to Buyer's operation facilities or leave the airport in a timely manner according to the schedule of the flights they are engaged in.

Notwithstanding the provisions of this Article 2.3.2.f, the foregoing insurance does not provide coverage for Embraer with respect to Services contemplated in this Article 2.3.2 for claims arising out of Embraer's legal liability as manufacturer and shall not operate to prejudice Buyer's right of recourse against Embraer or its employees or any employees of any subsidiary of Embraer in the event of gross negligence or willful misconduct of Embraer or such employees in the performance of the Services to be provided pursuant to this Agreement or its Attachments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;g.

The fuselage of the Aircraft shall be painted according to Buyer's colour and paint scheme, which shall be supplied to Embraer by Buyer on or before [\*\*\*] prior to the first Aircraft Contractual Delivery Date. The wings and the horizontal stabilizer shall be supplied in the standard colours, i.e., grey BAC707.

The choices of colour and paint scheme made by Buyer shall apply to all Aircraft, unless Buyer provides written notice of a new colour and paint scheme not less than [\*\*\*] prior to the relevant Aircraft Contractual Delivery Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.2** **INTERIOR FINISHING:** 

Buyer shall inform Embraer during the customer check list definition ("CCL"), to be held no later than [\*\*\*] prior to the applicable Aircraft Contractual Delivery Date, of its choice of materials and colours of all and any item of interior finishing such as seat covers, carpet, floor lining on galley areas, side walls and overhead lining, galley lining and curtain, from the choices offered by and available at Embraer.

Materials shall conform to the required standards and comply with all applicable regulations and airworthiness requirements. Delays in the delivery of BFE equipment or quality restrictions that prevent the installation thereof in the time frame required by the Aircraft manufacturing process shall entitle Embraer to either delay the delivery of the Aircraft for a period related to the delay of the BFE or present the Aircraft to Buyer without such BFE, in which case Buyer shall not be entitled to refuse acceptance of the Aircraft.

**ATTACHMENT "A7"<br>EMBRAER 175 AIRCRAFT CONFIGURATION (SkyWest/United Airlines)**<br>

&nbsp;&nbsp;&nbsp;&nbsp;**1.** **STANDARD AIRCRAFT** 

The Aircraft EMBRAER 175 (certification designation ERJ 170-200 LR) shall be manufactured according to [\*\*\*] although not attached hereto, is incorporated herein by reference, and (ii) the characteristics described in the items below.

&nbsp;&nbsp;&nbsp;&nbsp;**2.** **OPTIONAL EQUIPMENT:** 

[\*\*\*]

&nbsp;&nbsp;&nbsp;&nbsp;**3.** **FINISHING** 

The Aircraft will be delivered to Buyer as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.1** **EXTERIOR FINISHING:** 

The fuselage of the Aircraft shall be painted according to Buyer's colour and paint scheme, which shall be supplied to Embraer by Buyer on or before [\*\*\*] prior to the first Aircraft Contractual Delivery Date. The wings and the horizontal stabilizer shall be supplied in the standard colours, i.e., grey BAC707.

The choices of colour and paint scheme made by Buyer shall apply to all Aircraft, unless Buyer provides written notice of a new colour and paint scheme not less than [\*\*\*] prior to the relevant Aircraft Contractual Delivery Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.2** **INTERIOR FINISHING:** 

Buyer shall inform Embraer during the customer check list definition ("CCL"), to be held no later than [\*\*\*] prior to the applicable Aircraft Contractual Delivery Date, of its choice of materials and colours of all and any item of interior finishing such as seat covers, carpet, floor lining on galley areas, side walls and overhead lining, galley lining and curtain, from the choices offered by and available at Embraer. In case Buyer opts to use different materials and/or patterns, Embraer will submit to Buyer a Proposal of Major Change ("PMC") describing the impacts of such option, if any. Should Buyer not approve such PMC, the interior shall be built according to the choices offered by and available at Embraer.

Once defined, for the applicable CCL the choices of interior finishing made by Buyer shall apply to all applicable Aircraft. If Buyer requires an interior finishing for any Aircraft that is different from the original one informed to Embraer, Buyer shall present a written request to Embraer not less than [\*\*\*] prior to the relevant Aircraft Contractual Delivery Date and Embraer will submit the relevant quotation to the approval of Buyer within [\*\*\*] from the date such request is received by Embraer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.3** **BUYER FURNISHED EQUIPMENT (BFE) AND BUYER INSTALLED EQUIPMENT (BIE):** 

Buyer may choose to have carpets, tapestries, seat covers and curtain fabrics supplied to Embraer for installation in the Aircraft as BFE. Materials shall conform to the required standards and comply with all applicable regulations and airworthiness requirements. Delays in the delivery of BFE equipment or quality restrictions that prevent the installation thereof in the time frame required by the Aircraft manufacturing process shall entitle Embraer to either delay the delivery of the Aircraft for a period related to the delay of the BFE or present the Aircraft to Buyer without such BFE, in which case Buyer shall not be entitled to refuse acceptance of the Aircraft.

All BFE equipment shall be delivered in DDP conditions (INCOTERMS 2010) to C&D Zodiac – 14 Centerpointe Drive, La Palma, CA 90623, USA, or to another place to be timely informed by Embraer.

Galley inserts (such as coffee makers, water boilers, ovens), trolleys and standard units and medical kits, defibrillators and wheelchairs, as well as any other equipment classified as medical or pharmaceutical product, shall be acquired by Buyer and installed on the Aircraft by Buyer after delivery thereof as BIE.

Notwithstanding the above, Buyer shall [\*\*\*] in [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.4** **EMBRAER RIGHT TO PERFORM FOR BUYER:** 

If, after written notice from Embraer to Buyer, Buyer fails to make any choice or definition which Buyer is required to make within [\*\*\*] after such notice regarding the exterior and interior finishing of any Aircraft or to inform Embraer thereof, Embraer shall have the right, but not the obligation, to tender the Aircraft for delivery (a) painted white and (b) fitted with an interior finishing selected by Embraer at its reasonable discretion.

The taking of any such action by Embraer pursuant to this Article shall not constitute a waiver or release of any obligation of Buyer under the Purchase Agreement, nor a waiver of any event of default which may arise out of Buyer's non-performance of such obligation, nor an election or waiver by Embraer of any remedy or right available to Embraer under the Purchase Agreement.

No compensation to Buyer or reduction of the Aircraft Basic Price shall be due by virtue of the taking of any such actions by Embraer and Embraer shall be entitled to charge Buyer for the amount of the reasonable expenses incurred by Embraer in connection with the performance of or compliance with such agreement, as the case may be, payable by Buyer within [\*\*\*] from the presentation of the respective invoice by Embraer to Buyer.

If, after written notice from Embraer to Buyer, Buyer fails to make any choice or definition which Buyer is required to make within [\*\*\*] after such notice regarding the exterior and interior finishing of any Aircraft or to inform Embraer thereof, Embraer shall have the right, but not the obligation, to tender the Aircraft for delivery (a) painted white and (b) fitted with an interior finishing selected by Embraer at its reasonable discretion.

The taking of any such action by Embraer pursuant to this Article shall not constitute a waiver or release of any obligation of Buyer under the Purchase Agreement, nor a waiver of any event of default which may arise out of Buyer's non-performance of such obligation, nor an election or waiver by Embraer of any remedy or right available to Embraer under the Purchase Agreement.

No compensation to Buyer or reduction of the Aircraft Basic Price shall be due by virtue of the taking of any such actions by Embraer and Embraer shall be entitled to charge Buyer for the amount of the reasonable expenses incurred by Embraer in connection with the performance of or compliance with such agreement, as the case may be, payable by Buyer within [\*\*\*] from the presentation of the respective invoice by Embraer to Buyer.

&nbsp;&nbsp;&nbsp;&nbsp;**4.** **REGISTRATION MARKS, TRANSPONDER AND ELT CODES:**

Buyer may choose to have carpets, tapestries, seat covers and curtain fabrics supplied to Embraer for installation in the Aircraft as BFE. Materials shall conform to the required standards and comply with all applicable regulations and airworthiness requirements. Delays in the delivery of BFE equipment or quality restrictions that prevent the installation thereof in the time frame required by the E170+ Aircraft manufacturing process shall entitle Embraer to either delay the delivery of the E170+ Aircraft for a period related to the delay of the BFE or present the E170+ Aircraft to Buyer without such BFE, in which case Buyer shall not be entitled to refuse acceptance of the E170+ Aircraft.

The taking of any such action by Embraer pursuant to this Article shall not constitute a waiver or release of any obligation of Buyer under the Purchase Agreement, nor a waiver of any event of default which may arise out of Buyer's non-performance of such obligation, nor an election or waiver by Embraer of any remedy or right available to Embraer under the Purchase Agreement.

No compensation to Buyer or reduction of the E170+ Aircraft Basic Price shall be due by virtue of the taking of any such actions by Embraer and Embraer shall be entitled to charge Buyer for the amount of the reasonable expenses incurred by Embraer in connection with the performance of or compliance with such agreement, as the case may be, payable by Buyer within [\*\*\*] from the presentation of the respective invoice by Embraer to Buyer.

The taking of any such action by Embraer pursuant to this Article shall not constitute a waiver or release of any obligation of Buyer under the Purchase Agreement, nor a waiver of any event of default which may arise out of Buyer's non-performance of such obligation, nor an election or waiver by Embraer of any remedy or right available to Embraer under the Purchase Agreement.

No compensation to Buyer or reduction of the Aircraft Basic Price shall be due by virtue of the taking of any such actions by Embraer and Embraer shall be entitled to charge Buyer for the amount of the reasonable expenses incurred by Embraer in connection with the performance of or compliance with such agreement, as the case may be, payable by Buyer within [\*\*\*] from the presentation of the respective invoice by Embraer to Buyer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.5 The Aircraft Basic Price offered to Buyer for the E170+ Aircraft is based on the assumption that if, at Buyer's sole discretion, Buyer acquires a service bulletin to convert the [\*\*\*] configuration as provided in Attachment "A13" or Attachment "A17" to another configuration and it increases the number of seats, Buyer would acquire such service bulletin from Embraer or would reimburse Embraer as detailed in Article 3 of Amendment No. 9 to the Letter Agreement COM0029-13."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**5.** **OPTION AIRCRAFT** 

Article 21 of the Purchase Agreement shall be deleted and replaced by the following:

"Subject to the [\*\*\*], Buyer shall have the option to purchase [\*\*\*] Option Aircraft, to be delivered in accordance with Option Aircraft contractual delivery dates (each an "Option Aircraft Contractual Delivery Date") contained in Section 2 of Attachment "G" to this Agreement. The Option Aircraft will be E170+ Aircraft in the configuration described in Attachment "A13" and the Aircraft Basic Price shall be as provided in Article 3.1 unless, in each case, as otherwise agreed following the Amendment No. 28 Effective Date.

The Option Aircraft will be supplied in accordance with the following terms and conditions: 21.1

[\*\*\*]

21.2&nbsp;&nbsp;&nbsp;&nbsp;The unit basic price of the Option Aircraft shall be equal to the unit Aircraft Basic Price (the "Option Aircraft Basic Price").

21.3&nbsp;&nbsp;&nbsp;&nbsp;The Option Aircraft Basic Price shall be escalated according to the escalation formula subject of Attachment "D1" hereto, determining the Option Aircraft purchase price (the "Option Aircraft Purchase Price").

21.4&nbsp;&nbsp;&nbsp;&nbsp;The payment of the Option Aircraft Purchase Price shall be made for each Option Aircraft for which Buyer has exercised its option rights hereunder according to the following:

[\*\*\*]

21.5&nbsp;&nbsp;&nbsp;&nbsp;The option to purchase the Option Aircraft shall be exercised in [\*\*\*] groups of [\*\*\*] Option Aircraft each (the "Option Group" for purposes of this Article 21.5) no later than [\*\*\*] prior to [\*\*\*] the first Option Aircraft Contractual Delivery Date in such Option Group.

[\*\*\*]. Any Option Aircraft not exercised by Buyer as per the terms and conditions of this paragraph will automatically be converted to be a Purchase Right Aircraft and be subject to the terms and conditions of Article 22, [\*\*\*], and Embraer shall return to Buyer any payments made by Buyer towards the purchase of such converted Option Aircraft within [\*\*\*] Days following such deemed conversion. The Parties shall promptly thereafter execute an amendment to the Purchase Agreement documenting the Option Aircraft becoming Purchase Right Aircraft under Article 22.

21.6&nbsp;&nbsp;&nbsp;&nbsp;If the options are confirmed by Buyer as specified above, an amendment to the Purchase Agreement shall be executed by and between the Parties within [\*\*\*] following the Option

21.7&nbsp;&nbsp;&nbsp;&nbsp;Article 2.3.4 of Attachment "B" hereto sets forth the agreement regarding the product support package to be applied to the Option Aircraft."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**6.** **PURCHASE RIGHT AIRCRAFT** 

Article 22 of the Purchase Agreement shall be deleted and replaced by the following:

"22.1&nbsp;&nbsp;&nbsp;&nbsp;Embraer hereby grants Buyer the right to purchase up to [\*\*\*] E170+ Aircraft (the "Purchase Right Aircraft") configured as per Attachment "A13" and available to Buyer at the Aircraft Basic Price (as provided in Article 3.1 unless otherwise agreed following the Amendment No. 28 Effective Date) and on the same economic conditions that are applicable to the initial five Delta aircraft (referenced [\*\*\*] to [\*\*\*]) in Attachment "A13" to this Purchase Agreement (the "Purchase Right Basic Price"), which price is subject to the escalation conditions contained in Attachment "D1"."

22.2&nbsp;&nbsp;&nbsp;&nbsp;Subject to no material default on the part of the Buyer having occurred and be continuing under this Agreement, the right to purchase each of the Purchase Right Aircraft shall be exercised in at least [\*\*\*] groups of [\*\*\*] Purchase Right Aircraft (the "Purchase Right Group" for the purposes of this Article 22.2), by means of a written notice (the "Exercise Notice") from Buyer to Embraer no later than [\*\*\*]. The Exercise Notice shall furthermore contain Buyer's desired delivery months for the Purchase Right Aircraft to be exercised, which shall not be later than [\*\*\*] ("Purchase Right Aircraft Contractual Delivery Date"), and such right is subject to the existence of sufficient production capacity at Embraer to comply with Buyer's desirable delivery schedule as determined by Embraer in its sole discretion and subject to a required minimum Embraer production level of at least [\*\*\*] EMBRAER 175 aircraft annually, such production level driven by Buyer or any other customer, for years [\*\*\*] through [\*\*\*].

22.3&nbsp;&nbsp;&nbsp;&nbsp;If Embraer has not received an Exercise Notice for any unexercised Purchase Right Group on or before [\*\*\*], Buyer shall be deemed to have relinquished its right to acquire any unexercised Purchase Right Aircraft.

22.4&nbsp;&nbsp;&nbsp;&nbsp;Following receipt by Embraer of the Exercise Notice, Embraer shall inform Buyer if the desired Purchase Right Aircraft's Contractual Delivery Date requested by Buyer is acceptable; otherwise, Embraer shall inform Buyer the closest non-committed delivery position available for sale. If the desired Purchase Right Aircraft Contractual Delivery Date requested by Buyer is available as determined by Embraer in its sole discretion, then Embraer shall be obligated to provide Buyer with such delivery position.

22.5&nbsp;&nbsp;&nbsp;&nbsp;In the event Buyer and Embraer agree to the new Purchase Right Aircraft Contractual Delivery Date and in order to secure the Purchase Right Aircraft delivery positions, [\*\*\*].

22.6&nbsp;&nbsp;&nbsp;&nbsp;If the purchase rights are exercised by Buyer as specified above, and the Purchase Right Initial Deposit is paid by Buyer, an amendment to the Purchase Agreement shall be executed by and between the Parties within [\*\*\*] of the date of the Exercise Notice, setting forth the specific terms and conditions applicable to such Purchase Right Aircraft. The Parties agree that the terms and conditions relating specifically to the Purchase Right Aircraft shall be

Each Party shall inform the other Party, if not prohibited by applicable laws, of any situation of which it becomes aware that may result in a breach of this Clause.

The taking of any such action by Embraer pursuant to this Article shall not constitute a waiver or release of any obligation of Buyer under the Purchase Agreement, nor a waiver of any event of default which may arise out of Buyer's non-performance of such obligation, nor an election or waiver by Embraer of any remedy or right available to Embraer under the Purchase Agreement.

No compensation to Buyer or reduction of the Aircraft Basic Price shall be due by virtue of the taking of any such actions by Embraer and Embraer shall be entitled to charge Buyer for the amount of the reasonable expenses incurred by Embraer in connection with the performance of or compliance with such agreement, as the case may be, payable by Buyer within [\*\*\*] from the presentation of the respective invoice by Embraer to Buyer.

Buyer may choose to have carpets, tapestries, seat covers and curtain fabrics supplied to Embraer for installation in the Aircraft as BFE. Materials shall conform to the required standards and comply with all applicable regulations and airworthiness requirements. Delays in the delivery of BFE equipment or quality restrictions that prevent the installation thereof in the time frame required by the Aircraft manufacturing process shall entitle Embraer to either delay the delivery of the Aircraft for a period related to the delay of the BFE or present the Aircraft to Buyer without such BFE, in which case Buyer shall not be entitled to refuse acceptance of the Aircraft.

All BFE equipment shall be delivered in DDP conditions (INCOTERMS 2010) to C&D Zodiac – 14 Centerpointe Drive, La Palma, CA 90623, USA, or to another place to be timely informed by Embraer.

The taking of any such action by Embraer pursuant to this Article shall not constitute a waiver or release of any obligation of Buyer under the Purchase Agreement, nor a waiver of any event of default which may arise out of Buyer's non-performance of such obligation, nor an election or waiver by Embraer of any remedy or right available to Embraer under the Purchase Agreement.

No compensation to Buyer or reduction of the Aircraft Basic Price shall be due by virtue of the taking of any such actions by Embraer and Embraer shall be entitled to charge Buyer for the amount of the reasonable expenses incurred by Embraer in connection with the performance of or compliance with such agreement, as the case may be, payable by Buyer within [\*\*\*] from the presentation of the respective invoice by Embraer to Buyer.

&nbsp;&nbsp;&nbsp;&nbsp;**4.** **REGISTRATION MARKS, TRANSPONDER AND ELT CODES:**

21.2Subject to no material default on the part of the Buyer having occurred and be continuing under this Agreement on the date of exercise, the right to purchase each of the Purchase Right Aircraft must be exercised in groups (as set forth in further detail in Table 21A below, the "PRA Groups"), in whole or in part, by means of a written notice (each, an "Exercise Notice") from Buyer to Embraer. Buyer may exercise a portion of a PRA Group as long as a minimum of [\*\*\*] Purchase Right Aircraft are exercised in the Exercise Notice. The Exercise Notice must specify (i) the PRA Group, or portion of PRA Group, that is the subject of such notice and (ii) furthermore contain Buyer's desired delivery month within the related calendar year set forth in Table 21A below (the "Delivery Year") for Purchase Right Aircraft comprising such PRA Group, or portion of PRA Group, to be exercised, being understood and agreed that Seller will have no obligation or liability to deliver any Purchase Right Aircraft after [\*\*\*] ("Purchase Right Aircraft Contractual Delivery Date"), in which case, [\*\*\*].

Right Aircraft in any given year, however no more than [\*\*\*] Purchase Right Aircraft shall be delivered in any given year.

[\*\*\*]

21.4Following receipt by Seller of the Exercise Notice, Seller will inform Buyer if the desired Purchase Right Aircraft delivery date originally requested by Buyer is acceptable, otherwise, Seller will inform Buyer the closest non-committed delivery position available for sale. In the event the closest non-committed delivery positions are not available in the delivery year in Table 21A applicable to each PRA Group, the Parties, acting reasonably and in good faith, will review Table 21A to redistribute the Purchase Right Aircraft deliveries to another calendar year, and the Purchase Right Aircraft Contractual Delivery Date will be adjusted as necessary. Nevertheless, in no event shall any Purchase Right Aircraft be delivered after [\*\*\*].

21.5If Seller has not received the Exercise Notice for any PRA Group on or before the date set forth as the "Exercise Date" for such PRA Group in Table 21A above (the "Exercise Deadline"), Buyer will be deemed to have relinquished its right to acquire any and all unexercised Purchase Right Aircraft comprising such PRA Group, with no further obligation of Seller to sell or deliver any such unexercised Purchase Right Aircraft, and with no liability being incurred by either Party to the other with respect to such PRA Group or the related Purchase Right Aircraft.

Seller's obligation to sell to Buyer any of the Purchase Right Aircraft in any of the PRA Group specified in an Exercise Notice is subject to the existence of sufficient production capacity at Seller, as determined by Seller, to comply with Buyer's desired delivery schedule set forth in such Exercise Notice. In evaluating Buyer's Exercise Notice, Seller will [\*\*\*] to accommodate such request considering the non-committed delivery positions available for sale at the time of receipt by Seller of Buyer's Exercise Notice. Within [\*\*\*] after receipt by Seller of an Exercise Notice for any PRA Group and the related Purchase Right Aircraft for such PRA Group, Seller will notify Buyer in writing, if the desired delivery month for each such Purchase Right Aircraft requested by Buyer in such Exercise Notice is acceptable; otherwise Seller will notify Buyer the alternate closest non-committed delivery position(s) available for sale. Buyer will notify Seller in writing, within [\*\*\*] after receipt by Buyer of Seller notice, whether such alternate delivery position for any such Purchase Right Aircraft is acceptable or not, and if such alternate delivery position is not acceptable to Buyer, Buyer and Seller will negotiate in good faith for a period of [\*\*\*] to try to agree on an acceptable alternate delivery position for such Purchase Right Aircraft. If Buyer and Seller cannot agree on an alternate delivery position by the end of such period, the Exercise Notice will be canceled, in whole or in part, as applicable, without any further action from Buyer or Seller, [\*\*\*] with respect to such Purchase Right Aircraft.

21.6In the event Buyer and Seller agree to the new Purchase Right Aircraft Contractual Delivery Date and to secure the Purchase Right Aircraft delivery positions, Buyer must immediately remit to Seller [\*\*\*] for each exercised Purchase Right Aircraft (the "Purchase Right Initial Deposit"). The Purchase Right Aircraft payment terms and conditions will be in accordance with all terms and conditions contained in Article 4 of

Purchase Agreement COM0247-25 Page 20 of 26

------

this Agreement applicable to Aircraft configured as per Attachment "A", mutatis mutandis with the Purchase Right Initial Deposit being treated as the Initial Deposit for purposes of the foregoing.

21.7If the purchase rights are exercised by Buyer as specified above, and the relevant contractual delivery dates for each related Purchase Right Aircraft are agreed and the Purchase Right Aircraft Initial Deposit is paid by Buyer as specified above, an amendment to the Purchase Agreement will be executed by and between the Parties within [\*\*\*] of the date of the Exercise Notice, in case Seller accepts Buyer's desired delivery dates, or the date Buyer accepts in writing the alternative available slots offered by Seller, as applicable, setting forth the specific terms and conditions applicable to such Purchase Right Aircraft ("Purchase Right Amendment"). The Parties agree that the terms and conditions relating specifically to the Purchase Right Aircraft will be substantially similar to and no less favorable to Buyer than those terms and conditions set forth in this Agreement and its Attachments. Upon the execution of the Purchase Right Amendment for any exercised Purchase Right Aircraft, such exercised Purchase Right Aircraft and its corresponding delivery position will be reserved for purchase by Buyer and such delivery position has been removed from the market.

21.8If the Parties for any reason fail to agree on the available slots or to execute the amendment referred to above, then the purchase right with respect to such aircraft will be deemed relinquished, [\*\*\*].
