Executive Compensation

Our NEOs, consisting of our principal executive officer and our next two most highly compensated executive officers as of September 30, 2018, were:

Processes and Procedures for Compensation Decisions

Our Compensation Committee is responsible for the executive compensation programs for our executive officers and reports to our Board on its discussions, decisions and other actions. Typically, our Chief Executive Officer makes recommendations to our Compensation Committee, often attends Compensation Committee meetings and is involved in the determination of compensation for our executive officers, except that our Chief Executive Officer does not make recommendations as to his own compensation. Our Chief Executive Officer, and from time to time as necessary, in consultation with our Chief Financial Officer, makes recommendations to our Compensation Committee regarding short-term and long-term compensation for all of our executive officers (other than himself) based on our results, as well as an individual executive officer’s contribution toward these results and their performance toward individual goal achievement. Our Compensation Committee then reviews the recommendations and other data and makes decisions as to the total compensation for each executive officer, as well as each individual compensation component.

Our Compensation Committee is authorized, in its sole discretion, to retain the services of one or more compensation consultants, outside legal counsel and such other advisors as necessary to assist with the execution of its duties and responsibilities. Although our Compensation Committee has not retained a compensation consultant to date, it may do so in the future.

Finally, “ Good Reason ” means any of the following, if not cured within 20 days of our receipt of a notice of termination by Mr. Ornstein: (i) any change by us in Mr. Ornstein’s title, or any significant diminishment in Mr. Ornstein’s function, duties or responsibilities from those associated with his functions, duties or responsibilities as of January 1, 2011; (ii) any material breach of the employment agreement or any other agreement between us and Mr. Ornstein which remains uncured for a period of 10 days after Mr. Ornstein gives us notice of such breach; (iii) except with Mr. Ornstein’s prior written consent, relocation of Mr. Ornstein’s principal place of employment to a location greater than 50 miles from Phoenix, Arizona, or requiring Mr. Ornstein to provide his services outside of Maricopa County, Arizona, for more than 50% of his working days during any consecutive six-month period; or (iv) any reduction of Mr. Ornstein’s base salary, bonus opportunity or benefits, other than under circumstances in which we have imposed cuts in salary of other officers on an across-the-board basis (in which case the cuts to Mr. Ornstein’s compensation must not be in a greater percentage than the reduction imposed on any other officer).

Transactions With Related Persons in 2018

Related Party Transaction Policy

Our Board has a written policy and procedures for review and approval of transactions involving the Company and “related persons” (which includes our directors and executive officers or their immediate family members, or shareholders and their immediate family members owning 5% or more of our common stock). The policy applies to any transaction in which the Company is a participant and any related person has a direct or indirect material interest, excluding transactions: (a) involving payment or reimbursement of expenses of the related person incurred in the ordinary course of the related person’s service as a director or officer of the Company; (b) where the financial or compensatory arrangements are approved or ratified by our Board; (c) where the related person’s interest arises (i) only from such person’s position as a director of a corporation or organization which is a party to the transaction; (ii) only from such person’s direct or indirect ownership of less than a 10% equity interest in another person (other than a partnership, limited liability company, trust or similar entity) that is a party to the transaction; or (iii) from both such position and such ownership; (d) where the related person’s interest arises only from the ownership of a class of equity securities of the Company and all holders of that class receive the same benefits on a pro rata basis; and (e) where an immediate family member’s interest arises from his or her status as an employee of a firm, corporation or other entity for which he or she is not also an officer, director, general partner, or principal.

Our Audit Committee reviews and approves in advance all related person transactions. In determining whether to approve a related person transaction, our Audit Committee looks to whether the related person transaction is on terms and conditions no less favorable to the Company than may reasonably be expected in arm’s-length transactions with unrelated parties. Our Audit Committee will also consider such other factors as it may determine in circumstances of a particular transaction.

Our Audit Committee is responsible for reviewing the material facts of all related person transactions, subject to the exceptions described above. Our Audit Committee will either approve or disapprove the entry into the related person transaction. If advance approval is not feasible, the transaction will be considered and, if our Audit Committee determines it to be appropriate, ratified at our Audit Committee’s next regularly scheduled meeting. In determining whether to approve or ratify a transaction with a related person, our Audit Committee will take into account, among other factors that it determines to be appropriate, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction. Information relating to our transactions with related persons is set forth immediately below.

Transactions With Related Persons in 2018

The following is a summary, since the beginning of our the fiscal year ended September 30, 2018, of the transactions to which we have been a participant in which the amount involved, exceeded or will exceed $120,000, and in which any of our directors, executive officers or holders of more than 5% of our capital stock, or any member of the immediate family of the foregoing persons, had or will have a direct or indirect material interest.

American Capacity Purchase Agreement

As of September 30, 2018, we operated 64 CRJ-900 aircraft for American under our capacity purchase agreement with American (our “ American Capacity Purchase Agreement ”). In exchange for providing flight services under our American Capacity Purchase Agreement, we receive a fixed monthly minimum amount per aircraft under contract plus certain additional amounts based upon the number of flights and block hours flown during each month. In addition, we may also receive incentives

41

or incur penalties based upon our operational performance, including controllable on-time departures and controllable completion percentages. American also reimburses us for certain costs on an actual basis, including passenger liability and hull insurance and aircraft property taxes, all as set forth in our American Capacity Purchase Agreement. Other expenses, including fuel and certain landing fees, are directly paid to suppliers by American. In addition, American also provides, at no cost to us, certain ground handling and customer service functions, as well as airport-related facilities and gates at American hubs and cities where we operate. As of December 31, 2018, American held approximately 10.5% of our outstanding common stock, which interest American received in exchange for its claims in our bankruptcy proceeding. During our fiscal 2018, we recognized approximately $359.4 million of revenue under our American Capacity Purchase Agreement.

Indemnification Agreements

Our Second Amended and Restated Articles of Incorporation compel indemnification of our directors and officers and permit indemnification of our employees and other agents, in each case to the maximum extent permitted by Nevada law, and our Amended and Restated Bylaws provide for indemnification of our directors, officers, employees and other agents to the maximum extent permitted by Nevada law. In addition, we have entered into indemnification agreements with our directors and NEOs containing provisions which are in some respects broader than the specific indemnification provisions contained in Nevada law. The indemnification agreements may require us, among other things, to indemnify our directors and officers against certain liabilities that may arise by reason of their status or service as directors and officers and to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified.

Termination of Shareholders’ Agreements

In January 2019, we agreed to terminate various shareholders’ agreements with our 5% shareholders, including American Airlines, Inc., Penguin Lax, Inc. and P Marblegate Ltd., that contained voting covenants and irrevocable proxies in favor of our Board.

42

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) under the Exchange Act requires our directors and executive officers, and persons who own more than ten percent of a registered class of our equity securities, to file with the SEC initial reports of ownership and reports of changes in ownership of our common stock and other equity securities. Officers, directors and greater than ten percent shareholders are required by SEC regulation to furnish us with copies of all Section 16(a) forms they file.

To our knowledge, based solely on a review of the copies of such reports furnished to us and written representations that no other reports were required, during the fiscal year ended September 30, 2018, all Section 16(a) filing requirements applicable to our officers, directors and greater than 10% beneficial owners were complied with, except that (1) due to an inadvertent mistake, Mr. Skiados filed a late report on Form 4 related to the acquisition of restricted common stock awards under our 2018 Plan in August 2018 in exchange for the cancellation of all outstanding equity grants awarded to him, and (2) American Airlines, Inc. failed to timely file a Form 3 to report its initial statement of beneficial ownership of 2,500,000 shares of our common stock.

The purpose of the Plan is to advance the interests of the Company and its stockholders by providing an incentive to attract, retain and reward Eligible Employees of the Participating Company Group and by motivating such persons to contribute to the growth and profitability of the Participating Company Group. The Plan provides Eligible Employees with an opportunity to acquire a proprietary interest in the Company through the purchase of Stock.

The Company intends that the Section 423 Plan qualify as an “employee stock purchase plan” under Section 423 of the Code (including any amendments or replacements of such section), and the Section 423 Plan shall be so construed. The Non-423 Plan, which is not intended to qualify as an “employee stock purchase plan” under Section 423 of the Code, is intended to provide Eligible Employees employed by Participating Companies outside the United States with an opportunity to purchase shares of Stock pursuant to the terms and conditions of the Plan but not necessarily in compliance with the requirements of Section 423 of the Code.

4.2     Adjustments for Changes in Capital Structure. Subject to any required action by the stockholders of the Company and the requirements of Section 424 of the Code to the extent applicable, in the event of any change in the Stock effected without receipt of consideration by the Company, whether through merger, consolidation, reorganization, reincorporation, recapitalization, reclassification, stock dividend, stock split, reverse stock split, split-up, split-off, spin-off, combination of shares, exchange of shares, or similar change in the capital structure of the Company, or in the event of payment of a dividend or distribution to the stockholders of the Company in a form other than Stock (excepting regular, periodic cash dividends) that has a material effect on the Fair Market Value of shares of Stock, appropriate and proportionate adjustments shall be made in the number and kind of shares subject to the Plan, any limit on the number of shares which may be purchased by any Participant during an Offering Period (as described in Section 8.2), the number of shares subject to each Purchase Right, and in the Purchase Price in order to prevent dilution or enlargement of Participants’ rights under the Plan. For purposes of the foregoing, conversion of any convertible securities of the Company shall not be treated as “effected without receipt of consideration by the Company.” If a majority of the shares which are of the same class as the shares that are subject to outstanding Purchase Rights are exchanged for, converted into, or otherwise become (whether or not pursuant to an Ownership Change Event) shares of another corporation (the “ New Shares ” ), the Committee may unilaterally amend the outstanding Purchase Rights to provide that such Purchase Rights are for New Shares. In the event of any such amendment, the number of shares subject to, and the exercise price per share of, the outstanding Purchase Rights shall be adjusted in a fair and equitable manner as determined by the Committee, in its discretion. Any fractional share resulting from an adjustment pursuant to this Section shall be rounded down to the nearest whole number, and in no event may the Purchase Price be decreased to an amount less than the par value, if any, of the stock subject to the Purchase Right.

For purposes of participation in the Non-423 Plan, Eligible Employees shall include any other Employees of the applicable Non-423 Plan Participating Company to the extent that applicable Local Law requires participation in the Plan to be extended to such Employees, as determined by the Company.

5.2     Exclusion of Certain Stockholders. Notwithstanding any provision of the Plan to the contrary, no Employee shall be treated as an Eligible Employee and granted a Purchase Right under the Section 423 Plan if, immediately after such grant, the Employee would own, or hold options to purchase, stock of the Company or of any Parent Corporation or Subsidiary Corporation possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of such corporation, as determined in accordance with Section 423(b)(3) of the Code.

For purposes of an individual’s participation in or other rights, if any, under the Plan as of the time of the Company’s determination of whether or not the individual is an Employee, all such determinations by the Company shall be final, binding and conclusive as to such rights, if any, notwithstanding that the Company or any court of law or governmental agency subsequently makes a contrary determination as to such individual’s status as an Employee.

6.1     Offering Periods. The Plan shall be implemented by sequential Offerings of approximately six (6) months’ duration or such other duration as the Committee shall determine.

Date for an Offering Period shall not participate in the Plan for that Offering Period or for any subsequent Offering Period unless the Eligible Employee subsequently delivers a properly completed Subscription Agreement to the appropriate Company office or representative on or before the Subscription Date for such subsequent Offering Period. An Employee who becomes an Eligible Employee after the Offering Date of an Offering Period shall not be eligible to participate in that Offering Period but may participate in any subsequent Offering Period provided the Employee is still an Eligible Employee as of the Offering Date of such subsequent Offering Period.

7.2     Continued Participation. A Participant shall automatically participate in the next Offering Period commencing immediately after the final Purchase Date of each Offering Period in which the Participant participates provided that the Participant remains an Eligible Employee on the Offering Date of the new Offering Period and has not either (a) withdrawn from the Plan pursuant to Section 12.1, or (b) terminated employment or otherwise ceased to be an Eligible Employee as provided in Section 13. A Participant who may automatically participate in a subsequent Offering Period, as provided in this Section, is not required to deliver any additional Subscription Agreement for the subsequent Offering Period in order to continue participation in the Plan.

8.1     Grant of Purchase Right. Except as otherwise provided below, on the Offering Date of each Offering Period, each Participant in such Offering Period shall be granted automatically a Purchase Right consisting of an option to purchase the lesser of (a) that number of whole shares of Stock determined by dividing the Dollar Limit (determined as provided below) by the Fair Market Value of a share of Stock on such Offering Date or (b) the Share Limit (determined as provided below). The Committee may, in its discretion and prior to the Offering Date of any Offering Period, (i) change the method of, or any of the foregoing factors in, determining the number of shares of Stock subject to Purchase Rights to be granted on such Offering Date, or (ii) specify a maximum aggregate number of shares that may be purchased by all Participants in an Offering or on any Purchase Date within an Offering Period. No Purchase Right shall be granted on an Offering Date to any person who is not, on such Offering Date, an Eligible Employee. For the purposes of this Section, the “ Dollar Limit ” shall be determined by multiplying $2,083.33 by the number of months (rounded to the nearest whole month) in the Offering Period and rounding to the nearest whole dollar, and the “ Share Limit ” shall be determined by multiplying 300 shares by the number of months (rounded to the nearest whole month) in the Offering Period and rounding to the nearest whole share.

8.2     Calendar Year Purchase Limitation. Notwithstanding any provision of the Plan to the contrary, no Participant (whether participating in the Section 423 Plan or the Non-423 Plan) shall be granted a Purchase Right which permits his or her right to purchase shares of Stock under the Plan to accrue at a rate which, when aggregated with such Participant’s rights to purchase shares under all other employee stock purchase plans of a Participating Company intended to meet the requirements of Section 423 of the Code, exceeds Twenty-Five Thousand Dollars ($25,000) in Fair Market Value (or such other limit, if any, as may be imposed by the Code) for each calendar year in which such Purchase Right is outstanding at any time. For purposes of the preceding sentence, the Fair Market Value of shares purchased during a given Offering Period shall be determined as of the Offering Date for such Offering Period. The limitation described in this Section shall be applied in conformance with Section  423(b)(8) of the Code or any successor thereto and the regulations thereunder.

The Purchase Price at which each share of Stock may be acquired in an Offering Period upon the exercise of all or any portion of a Purchase Right shall be established by the Committee; provided, however, that the Purchase Price on each Purchase Date shall not be less than ninety percent (90%) of the lesser of (a) the Fair Market Value of a share of Stock on the Offering Date of the Offering Period or (b) the Fair Market Value of a share of Stock on the Purchase Date. Subject to adjustment as provided by the Plan and unless otherwise provided by the Committee, the Purchase Price for each Offering Period shall be ninety percent (90%) of the lesser of (a) the Fair Market Value of a share of Stock on the Offering Date of the Offering Period or (b) the Fair Market Value of a share of Stock on the Purchase Date.

10.     A CCUMULATION OF P URCHASE P RICE THROUGH P AYROLL D EDUCTION .

Except as provided in Section 11.1(b) with respect to a Non-United States Offering or except as otherwise provided by the Committee in connection with an Offering under the Non-423 Plan, shares of Stock acquired pursuant to the exercise of all or any portion of a Purchase Right may be paid for only by means of payroll deductions from the Participant’s Compensation accumulated during the Offering Period for which such Purchase Right was granted, subject to the following:

10.1     Amount of Payroll Deductions. Except as otherwise provided herein, the amount to be deducted under the Plan from a Participant’s Compensation on each pay day during an Offering Period shall be determined by the Participant’s Subscription Agreement. The Subscription Agreement shall set forth the percentage of the Participant’s Compensation to be deducted on each pay day during an Offering Period in whole percentages of not less than one percent (1%) (except as a result of an election pursuant to Section 10.3 to stop payroll deductions effective following the first pay day during an Offering) or more than fifteen percent (15%). The Committee may change the foregoing limits on payroll deductions effective as of any Offering Date.

10.2     Commencement of Payroll Deductions. Payroll deductions shall commence on the first pay day occurring on or following the Offering Date and shall continue to the end of the Offering Period unless sooner altered or terminated as provided herein.

10.3     Election to Change or Stop Payroll Deductions. During an Offering Period, a Participant may elect to increase or decrease the rate of or to stop deductions from his or her Compensation by delivering to the Company office or representative designated by the Company (including a third-party administrator designated by the Company) an amended Subscription Agreement authorizing such change on or before the “Change Notice Date.” The “ Change Notice Date ” shall be a date prior to the beginning of the first pay period for which such election is to be effective as established by the Company from time to time and announced to the Participants. A Participant who elects, effective following the first pay day of an Offering Period, to decrease the rate of his or her payroll deductions to zero percent (0%) shall nevertheless remain a Participant in such Offering Period unless the Participant withdraws from the Plan as provided in Section 12.

10.4     Administrative Suspension of Payroll Deductions. The Company may, in its discretion, suspend a Participant’s payroll deductions under the Plan as the Company deems advisable to avoid accumulating payroll deductions in excess of the amount that could reasonably be anticipated to purchase the maximum number of shares of Stock permitted (a) under the Participant’s

A-10

Purchase Right, or (b) during a calendar year under the limit set forth in Section 8.2. Unless the Participant has either withdrawn from the Plan as provided in Section 12.1 or has ceased to be an Eligible Employee, suspended payroll deductions shall be resumed at the rate specified in the Participant’s then effective Subscription Agreement either (i) at the beginning of the next Offering Period if the reason for suspension was clause (a) in the preceding sentence, or (ii) at the beginning of the next Offering Period having a first Purchase Date that falls within the subsequent calendar year if the reason for suspension was clause (b) in the preceding sentence.

10.5     Participant Accounts. Individual bookkeeping accounts shall be maintained for each Participant. All payroll deductions from a Participant’s Compensation (and other amounts received from a non-United States Participant pursuant to Section 11.1(b) or pursuant to an Offering under the Non-423 Plan) shall be credited to such Participant’s Plan account and shall be deposited with the general funds of the Company (except as otherwise required by Local Law in connecting with an Offering under the Non-423 Plan). All such amounts received or held by the Company may be used by the Company for any corporate purpose.

10.6     No Interest Paid. Interest shall not be paid on sums deducted from a Participant’s Compensation pursuant to the Plan or otherwise credited to the Participant’s Plan account (except as otherwise required by Local Law in connection with an Offering under the Non-423 Plan).

10.7     Voluntary Withdrawal from Plan Account. A Participant may withdraw all or any portion of the payroll deductions credited to his or her Plan account and not previously applied toward the purchase of Stock by delivering to the Company a written notice on a form provided by the Company for such purpose. A Participant who withdraws the entire remaining balance credited to his or her Plan account shall be deemed to have withdrawn from the Plan in accordance with Section 12.1. Amounts withdrawn shall be returned to the Participant as soon as practicable after the withdrawal and may not be applied to the purchase of shares in any Offering under the Plan. The Company may from time to time establish or change limitations on the frequency of withdrawals permitted under this Section, establish a minimum dollar amount that must be retained in the Participant’s Plan account, or terminate the withdrawal right provided by this Section.

11.     P URCHASE OF S HARES .

11.1     Exercise of Purchase Right.

(a)     Generally. Except as provided in Section 11.1(b), on each Purchase Date of an Offering Period, each Participant who has not withdrawn from the Plan and whose participation in the Offering has not otherwise terminated before such Purchase Date shall automatically acquire pursuant to the exercise of the Participant’s Purchase Right the number of whole shares of Stock determined by dividing (a) the total amount of the Participant’s payroll deductions accumulated in the Participant’s Plan account during the Offering Period and not previously applied toward the purchase of Stock by (b) the Purchase Price. However, in no event shall the number of shares purchased by the Participant during an Offering Period exceed the number of shares subject to the Participant’s Purchase Right. No shares of Stock shall be purchased on a Purchase Date on behalf of a Participant whose participation in the Offering or the Plan has terminated before such Purchase Date.

(b)     Purchase by Non-United States Participants for Whom Payroll Deductions Are Prohibited by Applicable Law. Notwithstanding Section 11.1(a), where payroll deductions on behalf of Participants who are citizens or residents of countries other than the United States (without regard to whether they are also citizens of the United States or resident aliens) are prohibited or made impracticable by applicable Local Law, the Committee may establish a separate Offering (a “ Non-United States Offering ” ) covering all Eligible Employees of one or more Participating

A-11

Companies subject to such prohibition or restrictions on payroll deductions. The Non-United States Offering shall provide another method for payment of the Purchase Price with such terms and conditions as shall be administratively convenient and comply with applicable Local Law. On each Purchase Date of the Offering Period applicable to a Non-United States Offering, each Participant who has not withdrawn from the Plan and whose participation in such Offering Period has not otherwise terminated before such Purchase Date shall automatically acquire pursuant to the exercise of the Participant’s Purchase Right a number of whole shares of Stock determined in accordance with Section 11.1(a) to the extent of the total amount of the Participant’s Plan account balance accumulated during the Offering Period in accordance with the method established by the Committee and not previously applied toward the purchase of Stock. However, in no event shall the number of shares purchased by a Participant during such Offering Period exceed the number of shares subject to the Participant’s Purchase Right. The Company shall refund to a Participant in a Non-United States Offering in accordance with Section 11.4 any excess Purchase Price payment received from such Participant.

11.2     Pro Rata Allocation of Shares. If the number of shares of Stock which might be purchased by all Participants on a Purchase Date exceeds the number of shares of Stock remaining available for issuance under the Plan or the maximum aggregate number of shares of Stock that may be purchased on such Purchase Date pursuant to a limit established by the Committee pursuant to Section 8.1 or Section 8.3, the Company shall make a pro rata allocation of the shares available in as uniform a manner as practicable and as the Company determines to be equitable. Any fractional share resulting from such pro rata allocation to any Participant shall be disregarded.

11.3     Delivery of Title to Shares. Subject to any governing rules or regulations, as soon as practicable after each Purchase Date, the Company shall issue or cause to be issued to or for the benefit of each Participant the shares of Stock acquired by the Participant on such Purchase Date by means of one or more of the following: (a) by delivering to the Participant evidence of book entry shares of Stock credited to the account of the Participant, (b) by depositing such shares of Stock for the benefit of the Participant with any broker with which the Participant has an account relationship, or (c) by delivering such shares of Stock to the Participant in certificate form.

11.4     Return of Plan Account Balance. Any cash balance remaining in a Participant’s Plan account following any Purchase Date shall be refunded to the Participant as soon as practicable after such Purchase Date. However, if the cash balance to be returned to a Participant pursuant to the preceding sentence is less than the amount that would have been necessary to purchase an additional whole share of Stock on such Purchase Date, the Company may retain the cash balance in the Participant’s Plan account to be applied toward the purchase of shares of Stock in the subsequent Purchase Period or Offering Period.

11.5     Tax Withholding. At the time a Participant’s Purchase Right is exercised, in whole or in part, or at the time a Participant disposes of some or all of the shares of Stock he or she acquires under the Plan, the Participant shall make adequate provision for the federal, state, local and foreign taxes (including social insurance), if any, required to be withheld by any Participating Company upon exercise of the Purchase Right or upon such disposition of shares, respectively. A Participating Company may, but shall not be obligated to, withhold from the Participant’s compensation the amount necessary to meet such withholding obligations. The Company or any other Participating Company shall have the right to take such other action as it determines to be necessary or advisable to satisfy withholding obligations for such taxes.

11.6     Expiration of Purchase Right. Any portion of a Participant’s Purchase Right remaining unexercised after the end of the Offering Period to which the Purchase Right relates shall expire immediately upon the end of the Offering Period.

A-12

11.7     Provision of Reports and Stockholder Information to Participants. Each Participant who has exercised all or part of his or her Purchase Right shall receive, as soon as practicable after the Purchase Date, a report of such Participant’s Plan account setting forth the total amount credited to his or her Plan account prior to such exercise, the number of shares of Stock purchased, the Purchase Price for such shares, the date of purchase and the cash balance, if any, remaining immediately after such purchase that is to be refunded or retained in the Participant’s Plan account pursuant to Section 11.4. The report required by this Section may be delivered or made available in such form and by such means, including by electronic transmission, as the Company may determine. In addition, each Participant shall be provided information concerning the Company equivalent to that information provided generally to the Company’s common stockholders.

12.     W ITHDRAWAL FROM P LAN .

12.1     Voluntary Withdrawal from the Plan. A Participant may withdraw from the Plan by signing and delivering to the Company office or representative designated by the Company (including a third-party administrator designated by the Company) a written or electronic notice of withdrawal on a form provided by the Company for this purpose. Such withdrawal may be elected at any time prior to the end of an Offering Period; provided, however, that if a Participant withdraws from the Plan after a Purchase Date, the withdrawal shall not affect shares of Stock acquired by the Participant on such Purchase Date. A Participant who voluntarily withdraws from the Plan is prohibited from resuming participation in the Plan in the same Offering from which he or she withdrew, but may participate in any subsequent Offering by again satisfying the requirements of Sections 5 and 7.1. The Company may impose, from time to time, a requirement that the notice of withdrawal from the Plan be on file with the Company office or representative designated by the Company for a reasonable period prior to the effectiveness of the Participant’s withdrawal.

12.2     Automatic Withdrawal from Offering and Re-enrollment. If the Fair Market Value of a share of Stock on a Purchase Date within an Offering Period (the “ Old Offering Period ”), other than the final Purchase Date of the Old Offering Period, is less than the Fair Market Value of a share of Stock on the Offering Date of the Old Offering Period, then every Participant in the Old Offering Period automatically shall be (a) withdrawn from the Old Offering Period immediately after the purchase of shares on such Purchase Date and (b) enrolled in a new Offering Period of the same duration as the full term of the Old Offering Period commencing on the trading day immediately following the purchase of shares (which shall be the Offering Date of the new Offering Period), provided that the Participant then remains an Eligible Employee.

12.3     Return of Plan Account Balance. Upon a Participant’s voluntary withdrawal from the Plan pursuant to Section 12.1, the Participant’s accumulated Plan account balance which has not been applied toward the purchase of shares of Stock shall be refunded to the Participant as soon as practicable after the withdrawal, without the payment of any interest (except as otherwise required by Local Law in connection with an Offering under the Non-423 Plan), and the Participant’s interest in the Plan and the Offering shall terminate. Such amounts to be refunded in accordance with this Section may not be applied to any other Offering under the Plan.

13.     T ERMINATION OF E MPLOYMENT OR E LIGIBILITY .

Upon a Participant’s ceasing, prior to a Purchase Date, to be an Employee of the Participating Company Group for any reason, including retirement, disability or death, or upon the failure of a Participant to remain an Eligible Employee, the Participant’s participation in the Plan shall terminate immediately. In such event, the Participant’s Plan account balance which has not been applied toward the purchase of shares of Stock shall, as soon as practicable, be returned to the Participant or, in the case of the Participant’s death, to the Participant’s beneficiary designated in accordance with

A-13

Section 20, if any, or legal representative, and all of the Participant’s rights under the Plan shall terminate. Interest shall not be paid on sums returned pursuant to this Section 13 (except as otherwise required by Local Law in connection with an Offering under the Non-423 Plan). A Participant whose participation has been so terminated may again become eligible to participate in the Plan by satisfying the requirements of Sections 5 and 7.1.

In the event of a Change in Control, the surviving, continuing, successor, or purchasing corporation or parent thereof, as the case may be (the “ Acquiring Corporation ” ), may, without the consent of any Participant, assume or continue the Company’s rights and obligations under outstanding Purchase Rights or substitute substantially equivalent purchase rights for the Acquiring Corporation’s stock. If the Acquiring Corporation elects not to assume, continue or substitute for the outstanding Purchase Rights, the Purchase Date of the then current Offering Period shall be accelerated to a date before the date of the Change in Control specified by the Committee, but the number of shares of Stock subject to outstanding Purchase Rights shall not be adjusted. All Purchase Rights which are neither assumed or continued by the Acquiring Corporation in connection with the Change in Control nor exercised as of the date of the Change in Control shall terminate and cease to be outstanding effective as of the date of the Change in Control.

Neither payroll deductions or other amounts credited to a Participant’s Plan account nor a Participant’s Purchase Right may be assigned, transferred, pledged or otherwise disposed of in any manner other than as provided by the Plan or by will or the laws of descent and distribution. (A beneficiary designation pursuant to Section 20 shall not be treated as a disposition for this purpose.) Any such attempted assignment, transfer, pledge or other disposition shall be without effect, except that the Company may treat such act as an election to withdraw from the Plan as provided in Section 12.1. A Purchase Right shall be exercisable during the lifetime of the Participant only by the Participant.

16.     C OMPLIANCE WITH A PPLICABLE L AW .

The issuance of shares of Stock or other property under the Plan shall be subject to compliance with all applicable requirements of federal, state and foreign securities law and other applicable laws, rules and regulations, and approvals by government agencies as may be required or as the Company deems necessary or advisable. A Purchase Right may not be exercised if the issuance of shares upon such exercise would constitute a violation of any applicable federal, state or foreign securities laws or other law or regulations or the requirements of any securities exchange or market system upon which the Stock may then be listed. In addition, no Purchase Right may be exercised unless (a) a registration statement under the Securities Act shall at the time of exercise of the Purchase Right be in effect with respect to the shares issuable upon exercise of the Purchase Right, or (b) in the opinion of legal counsel to the Company, the shares issuable upon exercise of the Purchase Right may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any shares under the Plan shall relieve the Company of any liability in respect of the failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a condition to the exercise of a Purchase Right, the Company may require the Participant to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation, and to make any representation or warranty with respect thereto as may be requested by the Company.

A Participant shall have no rights as a stockholder by virtue of the Participant’s participation in the Plan until the date of the issuance of the shares of Stock purchased pursuant to the exercise of the Participant’s Purchase Right (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date such shares are issued, except as provided in Section 4.3. Nothing herein shall confer upon a Participant any right to continue in the employ of the Participating Company Group or interfere in any way with any right of any Participating Company to terminate the Participant’s employment at any time.

18.     N OTIFICATION OF D ISPOSITION OF S HARES .

The Company may require the Participant to give the Company prompt notice of any disposition of shares of Stock acquired by exercise of a Purchase Right. The Company may require that until such time as a Participant disposes of shares of Stock acquired upon exercise of a Purchase Right, the Participant shall hold all such shares in the Participant’s name until the later of two years after the date of grant of such Purchase Right or one year after the date of exercise of such Purchase Right. The Company may direct that the certificates evidencing shares of Stock acquired by exercise of a Purchase Right refer to such requirement to give prompt notice of disposition.

19.     L EGENDS .

The Company may at any time place legends or other identifying symbols referencing any applicable federal, state or foreign securities law restrictions or any provision convenient in the administration of the Plan on some or all of the certificates representing shares of Stock issued under the Plan. The Participant shall, at the request of the Company, promptly present to the Company any and all certificates representing shares acquired pursuant to a Purchase Right in the possession of the Participant in order to carry out the provisions of this Section. Unless otherwise specified by the Company, legends placed on such certificates may include but shall not be limited to the following:

“THE SHARES EVIDENCED BY THIS CERTIFICATE WERE ISSUED BY THE CORPORATION TO THE REGISTERED HOLDER UPON THE PURCHASE OF SHARES UNDER AN EMPLOYEE STOCK PURCHASE PLAN AS DEFINED IN SECTION 423 OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED. THE TRANSFER AGENT FOR THE SHARES EVIDENCED HEREBY SHALL NOTIFY THE CORPORATION IMMEDIATELY OF ANY TRANSFER OF THE SHARES BY THE REGISTERED HOLDER HEREOF. THE REGISTERED HOLDER SHALL HOLD ALL SHARES PURCHASED UNDER THE PLAN IN THE REGISTERED HOLDER’S NAME (AND NOT IN THE NAME OF ANY NOMINEE).”

20.     D ESIGNATION OF B ENEFICIARY .

20.1     Designation Procedure. Subject to applicable Local Law and procedures, a Participant may file a written designation of a beneficiary who is to receive (a) shares and cash, if any, from the Participant’s Plan account if the Participant dies subsequent to a Purchase Date but prior to delivery to the Participant of such shares and cash, or (b) cash, if any, from the Participant’s Plan account if the Participant dies prior to the exercise of the Participant’s Purchase Right. If a married Participant designates a beneficiary other than the Participant’s spouse, the effectiveness of such designation may be subject to the consent of the Participant’s spouse. A Participant may change his or her beneficiary designation at any time by written notice to the Company.

20.2     Absence of Beneficiary Designation. If a Participant dies without an effective designation pursuant to Section 20.1 of a beneficiary who is living at the time of the Participant’s death,

21.     N OTICES .

All notices or other communications by a Participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received in the form specified by the Company at the location, or by the person, designated by the Company for the receipt thereof.

22.     A MENDMENT OR T ERMINATION OF THE P LAN .

The Committee may at any time amend, suspend or terminate the Plan, except that (a) no such amendment, suspension or termination shall affect Purchase Rights previously granted under the Plan unless expressly provided by the Committee, and (b) no such amendment, suspension or termination may adversely affect a Purchase Right previously granted under the Plan without the consent of the Participant, except to the extent permitted by the Plan or as may be necessary to qualify the Section 423 Plan as an employee stock purchase plan pursuant to Section 423 of the Code or to comply with any applicable law, regulation or rule. In addition, an amendment to the Plan must be approved by the stockholders of the Company within twelve (12) months of the adoption of such amendment if such amendment would authorize the sale of more shares than are then authorized for issuance under the Plan or would change the definition of the corporations that may be designated by the Committee as Participating Companies. Notwithstanding the foregoing, in the event that the Committee determines that continuation of the Plan or an Offering would result in unfavorable financial accounting consequences to the Company, the Committee may, in its discretion and without the consent of any Participant, including with respect to an Offering Period then in progress: (i) terminate the Plan or any Offering Period, (ii) accelerate the Purchase Date of any Offering Period, (iii) reduce the discount or the method of determining the Purchase Price in any Offering Period (e.g., by determining the Purchase Price solely on the basis of the Fair Market Value on the Purchase Date), (iv) reduce the maximum number of shares of Stock that may be purchased in any Offering Period, or (v) take any combination of the foregoing actions.

23.     N O R EPRESENTATIONS WITH R ESPECT TO T AX Q UALIFICATION .

Although the Company may endeavor to (a) qualify Purchase Rights for favorable tax treatment under the laws of the United States or jurisdictions outside of the United States ( e.g. , options granted under Section 423 of the Code) or (b) avoid adverse tax treatment ( e.g. , under Section 409A of the Code), the Company makes no representation to that effect and expressly disavows any covenant to maintain favorable or avoid unfavorable tax treatment, anything to the contrary in this Plan. The Company shall be unconstrained in its corporate activities without regard to the potential negative tax impact on Participants under the Plan.

24.     C HOICE OF L AW .

Except to the extent governed by applicable federal law, the validity, interpretation, construction and performance of the Plan and each Subscription Agreement shall be governed by the laws of the State of Nevada, without regard to its conflict of law rules.

IN WITNESS WHEREOF, the undersigned Secretary of the Company certifies that the foregoing sets forth the Mesa Air Group, Inc. 2019 Employee Stock Purchase Plan as duly adopted by the Board on January 28, 2019.
