DFW | [***]
ELP | [***]
HOU | [***]
IAH | [***]
PHX | [***]
SDF | [***]
TUS | [***]
Total across all MX locations: | [***]

d.Any changes to the foregoing lists of Maintenance Bases, Outstation Bases, or maintenance staffing levels must be pre-approved by American in writing.

e.Mesa shall (i) allocate its aircraft maintenance technicians to the Code Share Agreement in a manner no less favorable (in terms of both staffing levels and experience) to American than Mesa allocates its aircraft maintenance technicians to any other aircraft operated by Mesa and not covered by the Code Share Agreement, including those operated by or on behalf of other air carriers, and (ii) provide American, upon request, with any and all information that American may deem necessary or desirable to confirm that Mesa has taken all reasonable steps to do so; provided, however, that in no event shall Mesa be obligated to provide American with information that is subject to a confidentiality or nondisclosure agreement (further provided that in such event, Mesa shall use commercially reasonable efforts to redact any such confidential information from the information requested by American in order to provide such requested information to American).

f.Notwithstanding anything to the contrary in this Nineteenth Amendment, a maintenance staffing shortfall as of a particular Measurement Date will not be deemed to be a Failure in and of itself. However, if a Failure with respect to a Performance Metric also occurs as of such Measurement Date, then two (2) Failures will be deemed to have occurred (i.e., one (1) Performance Metric Failure and one (1) maintenance staffing Failure). For example, if Mesa’s Dedicated AMT staffing level as of a particular Measurement Date is [***], but no Failure occurs with respect to any Performance Metric as of such Measurement Date, then no Failure will be deemed to have occurred; however, if a CD0 Failure also occurs as of such Measurement Date, then two (2) Failures shall be deemed to have occurred as of such Measurement Date (i.e., Dedicated AMTs and CD0).

4. American Performance Criteria. During the Amendment Term, American will perform in accordance with the obligations described in this Section 4 (the “American Performance Criteria”).

4.1. Scheduling.

a.Not later than the date that is one hundred sixty (160) days prior to the first day of each month during which Mesa is obligated to provide Flight Services, American will provide Mesa’s block hour guidance for such month (the “160-Day Guidance”).

| RAA | =the daily weighted average number of Revenue Available Aircraft during such period; and

| N | =the number of days in such period.

d.During the Amendment Term, Mesa’s annual average stage length will be equal to Mesa’s 2018 annual average stage length for Flights under the Code Share Agreement, plus or minus [***]. Within thirty (30) days after American releases each Schedule proposal to Mesa, American agrees to, upon Mesa’s request, meet with Mesa (which may include telephonically) to discuss the average stage length of such Schedule.

4.2. Maintenance and Touch Time Allocations. Beginning as of May 1, 2019, American will provide a minimum monthly average of [***] hours of RON Touch Time per Scheduled Aircraft per Day (as defined below) for all Schedules. Within thirty (30) days after American releases each Schedule proposal to Mesa, American agrees to, upon Mesa’s request, meet with Mesa (which may include telephonically) to discuss the RON Touch Time per Scheduled Aircraft per Day of such Schedule. For the avoidance of doubt, nothing in this Section 4.2 shall be deemed to require American to provide any minimum amount of ground time at Maintenance Bases or Outstation Bases on any given calendar day during a Schedule period, so long as the monthly average RON Touch Time per Scheduled Aircraft per Day with respect to the period to which such Schedule relates is equal to or greater than [***] hours.

a.“RON Touch Time per Scheduled Aircraft per Day” means, with respect to any given Schedule, a number of hours calculated as follows:

| RTT | =HMx ÷ (Asc x D)

| HMx | =the aggregate number of hours during the period to which such Schedule relates that Maintenance RONs (as defined below) remain on the ground at Maintenance Bases and/or Outstation Bases, inclusive of all ground time between each Maintenance RON’s arrival at the applicable Maintenance Base or Outstation Base and its departure from such Maintenance Base or Outstation Base (for example, if a particular Maintenance RON arrives at an Outstation Base at 6:00 PM local time on June 1 and departs such Outstation Base at 7:00 AM local time on June 2, thirteen (13) hours of ground time will be attributed to such Maintenance RON; if a particular Maintenance RON arrives at an Outstation Base at 6:00 PM local time on June I and departs such Outstation Base at 7:00 AM local time on June 3, thirty-seven (37) hours of ground time will be attributed to such Maintenance RON);

| Asc | =the daily weighted average number of Scheduled Aircraft during the period to which such Schedule relates; and

| D | =the number of calendar days in the period to which such Schedule relates.

b.“Maintenance RON” means an Aircraft that (i) is scheduled to be on the ground at a Maintenance Base or Outstation Base at 4:00 AM local time on a given calendar day, and (ii) remains on the ground for at least three (3) hours on such calendar day before departing such Maintenance Base or Outstation Base.

c.“Scheduled Aircraft” means, with respect to any given date, (i) the number of Revenue Available Aircraft as of such date minus (ii) any Aircraft that are unscheduled as of such date.

c. Bonus payments to Mesa will not exceed [***] U.S. dollars [***] in the aggregate per calendar year.

5.2. Failures. Any failure by Mesa to comply with the Mesa Performance Criteria will be considered a “Failure.” Failures, as defined in this Section 5.2, in and of themselves, will not be deemed to be Events of Default under the Code Share Agreement. Mesa will have no cure rights for purposes of determining whether a Failure has occurred. American will have no right to terminate the Code Share Agreement as a result of any Failure.

5.3. Rolling Measurement Period Resets.

a.Upon the occurrence of a Failure with respect to any individual Mesa Performance Criterion with a rolling measurement period (i.e., forty-five (45) days or sixty (60) days), the rolling measurement period applicable to such Mesa Performance Criterion will reset such that an additional Failure with respect to such Mesa Performance Criterion may not occur until at least forty-five (45) or sixty (60) days, as applicable, after the Measurement Date on which the prior Failure occurred. Subject to Section 5.4 hereof, a Failure with respect to one (1) Mesa Performance Criterion will not reset the measurement period(s) applicable to any other Mesa Performance Criteria.

b.Upon the accrual of a performance bonus with respect to either CD0 or CCF, the rolling measurement period applicable to such Performance Metric will reset such that an additional bonus payment with respect to such Performance Metric may not accrue to Mesa until at least forty-five (45) or sixty (60) days, as applicable, after the Measurement Date on which the prior bonus payment accrued to Mesa. For the avoidance of doubt, the accrual of a bonus payment with respect to CD0 will not affect the measurement period applicable to CCF, and vice versa.

5.4. Maximum Frequency of Failures. Notwithstanding anything set forth in this Nineteenth Amendment to the contrary: (a) during the period beginning on May 1, 2019 and ending on August 31, 2019, no more than two (2) Failures may occur within any rolling sixty (60)-day period; and (b) during the period beginning on September 1, 2019 and continuing thereafter, no more than two (2) Failures may occur within any rolling forty-five (45)-day period. If two (2) Failures occur within any rolling sixty (60)- or forty-five (45)-day period, as applicable (the “First Failure” and “Second Failure,” respectively), then upon the occurrence of the Second Failure: (i) if the Second Failure relates to a Mesa Performance Criterion with a rolling measurement period, the rolling measurement period applicable to such Mesa Performance Criterion will reset in accordance with Section 5.3(a) hereof; and (ii) the rolling measurement periods applicable to all other Mesa Performance Criteria will be reset as of the Measurement Date on which the First Failure occurred, such that a third Failure, if any, may not occur until at least sixty (60) or forty-five (45) days, as applicable, after the Measurement Date on which the First Failure occurred.

5.5. Waiver if Mesa Outperforms Other Regional Air Carriers. Notwithstanding anything set forth in this Section 5 to the contrary, if a Failure occurs with respect to any Performance Metric, but Mesa’s performance with respect to such Performance Metric exceeds the performance of all of American’s other regional air carriers for the same Performance Metric during the same period (as determined by American in its sole discretion), such Failure will be waived. For example, if Mesa’s CCF as of a given Measurement Date is [***] (which would otherwise constitute a Failure), but none of American’s other regional air carriers’ CCF exceeds [***] as of the same Measurement Date, such Failure will be waived. If requested by Mesa, American shall provide reasonably detailed supporting evidence with respect to any conclusion that a Failure has occurred and Mesa’s performance with respect to such Performance Metric did not exceed the performance of all of American’s other regional air carriers for the same Performance Metric.

6. Withdrawal of Additional Aircraft.

6.1. Withdrawal Rights. Except as provided in Section 5.5 hereof, upon the occurrence of each Failure, American will accrue the right, exercisable in its sole discretion, to permanently withdraw one (1) Aircraft from the Code Share Agreement (each, a “Withdrawal Right”). Regardless of the number of Failures that occur, in no event may American exercise more than six (6) Withdrawal Rights.

6.2. Withdrawal Procedure. American may exercise its Withdrawal Rights as follows:

a.Within thirty (30) days following American’s determination that a Failure has occurred, American will provide to Mesa a written notice of American’s intent to exercise the resulting Withdrawal Right (a “Withdrawal Notice”), which will include the Aircraft withdrawal date; provided that (a) the withdrawal date may not be less than ninety (90) or more than one hundred eighty (180) days after the date of such Withdrawal Notice; and (b) American may not withdraw more than two (2) Aircraft from the Code Share Agreement in any single calendar month.

b.If American fails to provide a Withdrawal Notice within thirty (30) days following American’s discovery of a Failure, American will no longer be able to exercise that particular Withdrawal Right; provided, however, that American’s election not to exercise such Withdrawal Right will have no impact on American’s ability to exercise any other Withdrawal Rights based on other Failures.

c.Within thirty (30) days following Mesa’s receipt of each Withdrawal Notice, Mesa will provide to American a written notice specifying the tail number of the Aircraft to be withdrawn pursuant to such Withdrawal Right (a “Tail Number Notice”).

d.If Mesa fails to provide to American a Tail Number Notice within thirty (30) days following receipt of any Withdrawal Notice, Mesa will be deemed to have forfeited its right to determine the tail number of the Aircraft to be withdrawn pursuant to that particular Withdrawal Right, and American will determine, in its sole discretion, the tail number of the Aircraft to be withdrawn pursuant to such Withdrawal Right.

6.3. Non-Exclusive Remedy. Subject to Section 5.2 hereof, American’s Withdrawal Rights will be cumulative, and not exclusive, of all remedies available to American under the Code Share Agreement or otherwise. During the Amendment Term, Section 15 of the Sixteenth Amendment shall be deemed to be of no force or effect.

7. Mesa’s Aircraft Withdrawal Option.

7.1. Mesa Option. If two (2) or more Failures occur, then upon the occurrence of the second Failure and each subsequent Failure, Mesa will accrue the right, exercisable only once in its sole discretion, to permanently withdraw no fewer than six (6) aircraft from the CSA (the “Mesa Option”).

7.2. Procedure. Mesa may exercise the Mesa Option as follows:

a.Within thirty (30) days following Mesa’s receipt of a Withdrawal Notice relating to the second Failure or any subsequent Failure, Mesa will provide to American a written notice of Mesa’s intent to exercise the Mesa Option (an “Option Notice”), which will include the following information:

i.The tail number of each aircraft to be withdrawn pursuant to the Mesa Option; and

Page 15

[***]=[CONFIDENTIAL PORTION HAS BEEN OMITTED BECAUSE IT (I) IS NOT MATERIAL AND (II) WOULD BE COMPETITIVELY HARMFUL IF PUBLICLY DISCLOSED]

ii. The withdrawal date for each aircraft; provided that (a) the withdrawal dates may not be less than ninety (90) or more than one hundred eighty (180) days after the date of such Option Notice and (b) Mesa may not withdraw more than two (2) aircraft from the CSA in any single calendar month.

b.If Mesa fails to provide an Option Notice to American within thirty (30) days following Mesa’s receipt of a Withdrawal Notice relating to a particular Failure, Mesa may not exercise the Mesa Option with respect to that particular Failure; provided, however, that Mesa’s election not to exercise the Mesa Option with respect to such Failure will have no impact on Mesa’s ability to exercise the Mesa Option based on other Failures.

8. Remaining Aircraft. The withdrawal of any Aircraft pursuant to this Nineteenth Amendment will not modify in any way either Party’s obligations with respect to the expiration of the Code Share Agreement as to the remaining Aircraft, including without limitation the timing of such expiration(s). This Section 8 will survive the expiration of this Nineteenth Amendment.

9. Compensation.

a.In addition to any amounts otherwise payable by American to Mesa pursuant to the Code Share Agreement, American will pay to Mesa the following amounts (the “Additional Monthly Compensation”):

i.[***] in April 2019;

ii.[***] per month beginning in May 2019 and ending in October 2019; and

iii.[***] per month beginning in November 2019 and ending in December 2020, which shall be solely to the extent that Mesa meets or exceeds the Mesa Performance Criteria thresholds contained in Sections 3.2(b)(i) (MEL Counts), 3.2(b)(ii) (CCF), 3.2(b)(iii) (MxD60), 3.2(b)(iv) (CD0) and 3.3(c) – (f) (Maintenance and Staffing) hereof during such relevant month; provided that solely for purposes of this Section 9(a)(iii), the Mesa Performance Criteria described herein shall be measured on a calendar month basis using the thresholds provided in the aforementioned Sections for Measurement Dates after August 31, 2019. If any Failure occurs within an applicable calendar month, American shall not be required to pay Mesa and Mesa shall not be entitled to the Additional Monthly Compensation for such calendar month.

b.This Section 9 will survive the expiration of this Nineteenth Amendment.

10. Mesa’s Obligation to Fly the Schedule. Mesa acknowledges and reaffirms its obligation to fly the Schedule established and provided by American.

11. Calculations.

11.1. Source Data. Mesa acknowledges and agrees that American may rely on American’s own data for purposes of calculating Mesa’s (and, if applicable, American’s other regional operators’) performance with respect to all Performance Metrics.

11.2. Rounding. The final result of each MEL Count calculation shall be rounded to the nearest [***] of an MEL. The final result of each Performance Metric calculation other than MEL Counts shall be

Page 16

[***]=[CONFIDENTIAL PORTION HAS BEEN OMITTED BECAUSE IT (I) IS NOT MATERIAL AND (II) WOULD BE COMPETITIVELY HARMFUL IF PUBLICLY DISCLOSED]

rounded to the nearest [***] of a percent. The final result of each calculation of Dedicated AMT staffing levels under Section 3.3(c) shall be rounded to the nearest [***]. For example:

a.if Mesa’s actual calculated MEL Count as of a given Measurement Date is [***], Mesa’s MEL Count as of such Measurement Date shall be deemed to be [***];

b.if Mesa’s actual MEL Count as of such Measurement Date is [***], Mesa’s MEL Count as of such Measurement Date shall be deemed to be [***];

c.if Mesa’s actual calculated CCF as of a given Measurement Date is [***], Mesa’s CCF as of such Measurement Date shall be deemed to be [***];

d.if Mesa’s actual calculated CCF as of such Measurement Date is [***], Mesa’s CCF as of such Measurement Date shall be deemed to be [***];

e.if Mesa’s actual Dedicated AMT staffing percentage as of a given Measurement Date is [***], Mesa’s Dedicated AMT staffing percentage as of such Measurement Date shall be deemed to be [***]; and

f.if Mesa’s actual Dedicated AMT staffing percentage as of such Measurement Date is [***], Mesa’s Dedicated AMT staffing percentage as of such Measurement Date shall be deemed to be [***].

12. Miscellaneous

12.1.Except as expressly set forth in this Nineteenth Amendment, all of the terms and conditions, including all obligations, rights, and remedies, currently existing under the Code Share Agreement shall remain in full force and effect and be applicable to this Nineteenth Amendment. In the event of a conflict between the Nineteenth Amendment and the Code Share Agreement, the Nineteenth Amendment shall control during the Amendment Term.

12.2.Each Party hereby reserves all rights, remedies and defenses they may have under the Code Share Agreement or otherwise. In addition, neither Party waives any of the other Party’s defaults, past, current or future. The foregoing notwithstanding, each Party hereby covenants and agrees that, in the event that such Party has claims of any kind against the other Party arising under the Code Share Agreement and existing as of the Effective Date of this Nineteenth Amendment, such Party will not bring any such claim during the Amendment Term.
