CRJ Fleet Expansion. Pursuant to the Aircraft Contract, Mesa shall have the right to acquire an additional 83 CRJ Aircraft, 43 by virtue of firm orders (the “Firm Aircraft”) and 40 by virtue of options (the “Option Aircraft”), in the configuration, with the seating capacity and at the times set forth on Exhibit A, attached hereto. The Firm Aircraft and Option Aircraft will consist of CRJ Models 200s, 700s and 900s as set forth in Exhibit A. For purposes of this Agreement, the CRJ Model 200s shall be a “CRJ Subfleet” and the CRJ Model 700s and 900s shall be a “CRJ Subfleet”.

Each of the Firm Aircraft shall be placed into Flight Services by Mesa in the calendar months set forth on Exhibit A (the “Delivery Schedule”). The Firm Aircraft to be delivered in each of the calendar months from and including October, 2003 to and including June, 2004 may be either CRJ Model 700s or 900s (the “Convertible Firm Aircraft”). AWA, by written notice to Mesa, given on or before the last day of the 18^th calendar month prior to the delivery of each Convertible Firm Aircraft, shall advise Mesa as to which model is to be added to the Fleet (the “Firm Selection Notice”). For example, for the CRJ to be delivered in October, 2003, AWA must provide the Firm Selection Notice by April 31, 2002. If AWA does not provide the Firm Selection Notice timely, then AWA shall be deemed to have elected to have a CRJ Model 700 added to the Fleet. Mesa shall provide AWA with at least 90 days‘ prior written notice of the week each of the Firm Aircraft will be placed into Flight Service under this Agreement and at least 60 days’ prior written notice of the date on which each of the Firm Aircraft will be placed into Flight Service under this Agreement (each, a “Scheduled Delivery Date”).

AWA shall have the options to expand the CRJ Fleet by up to 40 additional CRJs from the Option Aircraft. On or before each option “Exercise Date” (as set forth on Exhibit A), AWA, by written notice to Mesa (the “Option Notice”), shall have the option to require Mesa to increase the CRJ Subfleet by the addition of the

applicable CRJ Aircraft in the applicable “In Service Months” (as set for on Exhibit A)(each, a “Fleet Expansion Option”). Each Option Notice shall specify whether AWA is selecting either a CRJ Model 700 or 900. If the Option Notice does not specify the CRJ Model, then AWA shall be deemed to have selected a CRJ Model 700. The Fleet Expansion. Options are separate and individual options and may be exercised or not exercised on a separate and individual basis. The Aircraft that are the subject of each Fleet Expansion Option shall be added to the Fleet by Mesa in the applicable In Service Months. Mesa shall provide AWA with at least 90 days prior written notice of the week each Option Aircraft will be placed into Flight Service under this Agreement and at least 60 days’ prior written notice of the Scheduled Delivery Date for each Option Aircraft that is the subject of each exercised Fleet Expansion Option.

Mesa shall not be liable to AWA for the failure to deliver any Firm Aircraft or Option Aircraft on the Scheduled Delivery Date (a “Failed Delivery”) if: (i) the failure to deliver is the result of the manufacturer’s failure to deliver the Aircraft to Mesa as a result of acts of terrorism, hostilities, war, strikes, labor disputes, work stoppages beyond the manufacturer’s control, fire, act of government or court order; (ii) Mesa uses commercially reasonable efforts to acquire a replacement aircraft for the Aircraft that was not delivered; and (iii) Mesa pays to AWA any compensation, damages or award obtained by Mesa from the manufacturer as a result of the Failed Delivery (an “Excused Failure”). In the event of a Failed Delivery, Mesa shall use commercially reasonable efforts to obtain the applicable Aircraft as soon as practicable after the Scheduled Delivery Date. If the Aircraft that is the subject of a Failed Delivery is not delivered within 90 days after the Scheduled Delivery Date, then AWA shall have the option to elect not to include such Aircraft under this Agreement by providing written notice to Mesa at any time prior to the actual delivery of such Aircraft. If a Failed Delivery is not the result of an Excused Failure, then AWA shall have all rights and remedies under this Agreement for such Failed Delivery.

The “DOT Complaint Rate” is defined as the number of consumer complaints received by the DOT for a given calendar year expressed in terms of the number of complaints per 100,000 passengers flown during that calendar year by Mesa and AWA; provided, however, that the DOT Complaint Rate shall exclude consumer complaints relating solely to (i) overbooking; (ii) fares; (iii) Aircraft size or suitability; (iv) schedule; and (v) food service. For purposes of this Agreement, “AWA’s DOT Complaint Rate” shall mean AWA’s actual DOT Complaint Rate multiplied by [***]. DOT complaints made against AWA for America West Express service shall be allocated to Mesa for the purpose of calculating Mesa’s and AWA’s DOT Complaint Rates. If Mesa’s DOT Complaint Rate exceeds AWA’s DOT Complaint Rate in any calendar year during the Term of this Agreement, Mesa, within 10 days after receipt of written demand from AWA, shall pay to AWA a penalty equal to [***] multiplied by the amount by which Mesa’s DOT Complaint Rate exceeds AWA’s DOT Complaint Rate. For example, if AWA’s DOT Complaint Rate for a given year is [***] per 100,000 passengers and Mesa’s is [***] per 100,000 passengers, Mesa would pay AWA the product of [***] x [***]. On each anniversary date of the Contract Date, the penalty payment amount shall be increased by the increase in the CPI, as determined in accordance with Section 7.4.

Mishandled Baggage Rate Criteria. Commencing January 1, 2002, Mesa shall not permit its monthly MBR (defined below) for Flight Services to exceed the monthly MBR of AWA. The “MBR” is defined as the number of lost baggage claims entered into the world tracer system for a given month expressed in the terms of the number of entries per 1,000 bags handled during that calendar month by Mesa and AWA. Mesa shall enter all lost baggage claims into the world tracer system within 2 hours after the lost baggage claim is made by a passenger. If Mesa’s MBR exceeds AWA’s MBR by [***] or more in any calendar month during the Term of this Agreement, Mesa, within 10 days after receipt of written demand from AWA, shall pay to AWA a penalty equal to [***]. If Mesa’s MBR exceeds AWA’s MBR for three consecutive calendar months, Mesa, within 10 days after receipt of written demand, shall pay to AWA an additional penalty of [***]for such three-month period and for each consecutive month thereafter that Mesa’s MBR exceeds AWA’s MBR, the penalty shall be [***] per month. On each anniversary date of the Contract Date, the penalty payment amount shall be increased by the increase in the CPI, as determined in accordance with Section 7.4.

On Time Performance Rate Criteria. Mesa shall not permit Mesa’s OTP Rate (as defined below) for any Six Month Period (as defined below) to fall below: (i) [***] percentage points above AWA’s OTP Rate for Schedules operated by Mesa out of the Phoenix Sky Harbor International hub; and (ii) [***] percentage points below the AWA’s OTP Rate for Schedules operated out of the Columbus, Ohio

hub (the “OTP Rate Threshold”). The Phoenix Sky Harbor International hub and Columbus hub are each referred to as a “Hub.” The “OTP Rate” is defined as the percentage determined by dividing the number of flight segments not Delayed (as defined below) by the total number of flight segments during the applicable Six Month Period. For purposes of this Agreement, “Delayed” means a flight segment that does not arrive at the destination within [***] after the scheduled arrival time. All Flights will be included for calculating the OTP Rate. A canceled flight (except ones cancelled because of no passengers and the reasons set out in Section 5.4(v)) is a Delayed flight. To the extent that Mesa’s OTP Rate for either Hub Schedule falls below the applicable OTP Rate Threshold for any Six Month Period, Mesa, within 10 days after receipt of written demand, shall pay to AWA the OTP Penalty Amount (as defined below) for each percentage point, or portion thereof, by which Mesa’s OTP Rate for either Hub Schedule falls below the OTP Rate Threshold for such Six Month Period. The “OTP Penalty Amount” for each Hub is an amount equal to [***] times a fraction, the numerator of which is the daily average of Aircraft providing Flight Services to and from the Hub during the applicable Six Month Period and the denominator of which is the daily average of all Aircraft providing Flight Services during the applicable Six Month Period. On each anniversary date of the Contract Date the dollar amounts used for calculating the OTP Penalty Amount shall be increased by the increase in the CPI, as determined in accordance with Section 7.4. AWA, within 10 days after receipt of written demand, shall pay to Mesa [***] for each percentage point, or portion thereof, by which Mesa’s OTP Rate system wide exceeds [***] for any Calendar Quarter. On each anniversary date of the Contract Date, the bonus amount shall be increased by the increase in CPI, as determined in accordance with Section 7.4. “Six Month Period” means each January 1 — June 30 and July 1 — December 31 and “Calendar Quarter” means each 3 calendar month period commencing January 1 of each year.

Flight Completion Factor. Mesa shall not permit its FCF (defined below) for any Calendar Quarter to fall below: (i) [***] for Schedules operated out of the Phoenix Sky Harbor International Airport Hub; and (ii) [***] for Schedules operated out of the Columbus, Ohio Hub (each, an “FCF Threshold”). “FCF” is defined as the percentage of published, scheduled Flights completed for a Calendar Quarter. Flights not completed due to: (i) weather; (ii) cancellation or overflight because of no passengers; (iii) air traffic control cancellations; (iv) cancellations resulting from an emergency airworthiness directive from the FAA affecting all aircraft similarly equipped to the Aircraft in any Subfleet (not just those owned or operated by Mesa); or (v) cancellations resulting from the sole acts or omissions of AWA or its employees, including, without limitation, damage to an Aircraft, will not be included in either the numerator or denominator for calculating the FCF. Mesa, within 10 days after receipt of written demand, shall pay to AWA the FCF Penalty Amount for each tenth of a percentage point, or portion thereof, by which Mesa’s FCF for either Hub Schedule falls below the applicable FCF Threshold. The “FCF Penalty Amount” for each Hub is an amount equal to [***] times a fraction, the numerator of which is the daily average of Aircraft providing Flight Services to and from the Hub during the

Calendar Quarter and the denominator of which is the daily average of all Aircraft providing Flight Services under this Agreement during the Calendar Quarter. On each anniversary date of the Contract Date the dollar amount used for calculating the FCF Penalty Amount shall be increased by the increase in the CPI, as determined in accordance with Section 7.4. AWA, within 10 days after receipt of written demand, shall pay to Mesa [***] for each tenth of a percentage point by which Mesa’s FCF system wide exceeds [***] in any Calendar Quarter. On each anniversary date of the Contract Date, the bonus amount shall be increased by the increase in CPI, as determined in accordance with Section 7.4.

Records. Within 5 days after the end of each calendar month Mesa shall provide to AWA statements certified by Mesa’s chief financial officer as to Mesa’s OTP Rate and FCF for the prior calendar month and, as applicable, the prior Calendar Quarter and Six Month Period, together with such supporting documentation and information as AWA may request. AWA or its designee, upon 2 business days’ prior written notice, may review, at Mesa’s corporate or other relevant offices, all records and files maintained by Mesa in connection with on-time performance and flight completions. If AWA’s or its designee’s review of the records or files reveals that Mesa has under or overstated, as applicable, Mesa’s OTP Rate or FCF, then Mesa, upon demand, shall pay all sums due based on the accurate calculations, the actual out-of-pocket costs and expenses of AWA in completing such review and the applicable penalties payable based on such new calculation. If such under or overstatement is willful or intentional, then Mesa, within 10 days after receipt of written demand, shall pay to AWA an amount equal to [***] per occurrence.

Limitation on Applicability of Standards, Criteria, Incentives, and Penalties. AWA acknowledges that Mesa and the Affiliated Service Providers operate flights and provide flight services and other services under their own names and/or under names or service marks other than America West Express using aircraft that are not included in the Fleet and that are not subject to this Agreement. Notwithstanding any other term, condition or provision hereof to the contrary, the standards, criteria, incentives and penalties set forth above in this Section 5 apply only to Flight Services, Flights and Other Services performed by Mesa and the Affiliated Service Providers hereunder operating as America West Express and not to any other flights, flight services or other services performed by Mesa and the Affiliated Service Providers under their own names or under a name or service ▇▇▇▇ other than America West Express. Thus, in calculating Mesa’s DOT Complaint Rate, the MBR, the OTP Rate, the FCF, and all incentives and penalties set forth above, only Flight Services and Other Services performed by Mesa and the Affiliated Service Providers under the service ▇▇▇▇ America West Express shall be taken into account in calculating such rates and assessing such incentives and penalties.

Irregular Operations. The misconnect and denied boarding benefits provided by Mesa to passengers (each, a “Misconnect Benefit Package”) shall be similar in amount and scope to those offered by AWA in similar circumstances and geographic areas (the “AWA

Standards”). AWA shall not be required to reimburse Mesa for any Misconnect Benefit Package which is in excess of the AWA Standards.

Payment of Fees/Revenue Sharing. Commencing on the Effective Date and retroactive to the Contract Date, Mesa and AWA hereby agree to pay the following sums as consideration for this Agreement and the provision of the Flight Services and Other Services provided for herein:

Mesa Actual Costs. AWA, in accordance with Section 7.5, shall reimburse to Mesa the following actual costs and expenses actually paid by Mesa in connection with performing the Flight Services and Other Services (“Actual Costs”):

Hull insurance premiums and commissions paid by Mesa for each Aircraft for the prior calendar month. Insurance shall be allocated and paid by AWA on a monthly basis equally over the applicable premium period for which the insurance is paid. Insurance shall be prorated by Mesa in any premium period during which an Aircraft is added or deleted from this Agreement. If the monthly insurance payments made by AWA are less than the actual premiums paid by Mesa, then AWA shall pay such excess in the month Mesa pays the insurance premiums. If the monthly payments made by AWA exceed the actual insurance premiums, then AWA shall be entitled to a credit against the next payment of the Actual Costs in an amount equal to such overpayment. Mesa, within 10 days after receipt, shall provide AWA with copies of all premium notices received for insurance premiums.

Liability insurance premiums and commissions paid by Mesa for the Flight Services on a revenue passenger mile basis. Insurance shall be allocated and paid on a monthly basis equally over the applicable premium period for which the insurance is paid. Insurance shall be prorated by Mesa in any premium period during which this Agreement commences, terminates or expires. If the monthly insurance payments made by AWA are less than the actual premiums paid by Mesa, then AWA shall pay such excess in the month Mesa pays the insurance premiums. If the monthly payments made by AWA exceed the actual insurance premiums, then AWA shall be entitled to a credit against the next payment of the Actual Costs in an amount equal to such overpayment. Mesa, within 10 days after receipt, shall provide AWA with copies of all premium notices received for insurance premiums.

Property taxes paid by Mesa for each Aircraft or the Fleet. Property taxes shall be allocated and paid on a monthly basis equally over the applicable tax period for which the property taxes are assessed and paid. If an Aircraft is added to the Fleet after property taxes are assessed for a tax period and Mesa does not owe taxes for such Aircraft for such tax period, then AWA shall not pay property taxes on the Aircraft for such tax period. AWA shall pay the full year property

taxes for the year in which an Aircraft is deleted from the Fleet in the manner provided herein if such Aircraft is not placed in revenue service outside this Agreement (in which case such taxes shall be prorated). If the monthly tax payments made by AWA are less than the actual property taxes assessed and paid by Mesa, then AWA shall pay such excess in the month Mesa pays the property taxes. If the monthly payments made by AWA exceed the actual property taxes assessed, then AWA shall be entitled to a credit against the next payment of Actual Costs in an amount equal to such overpayment. Mesa, within 10 days after receipt, shall provide AWA with copies of all tax notices received for property taxes assessed against any portion of the Fleet.

De-Icing expenses paid by Mesa for each Aircraft for the prior calendar month.

Fuel costs paid by Mesa during the prior calendar month, calculated as gallons of fuel burned per hour. If in any calendar month Mesa’s estimated fuel costs exceed the Actual Costs for fuel for such calendar month by more than 3%, then thereafter, for the purpose of calculating Estimated Costs pursuant to Section 7.5 below, Mesa shall use AWA’s fuel forecast for the fuel costs.

Landing fees calculated per Flight departure incurred during the prior calendar month.

Security outside AWA Service Locations calculated per America West Express passenger.

Passenger and ground handling costs incurred at stations maintained by Mesa more particularly described on Exhibit B (“Station Costs”), not to exceed in each calendar year the amount set forth in the budget for each calendar year (the “Station Budget”); provided, however, that if AWA changes a Schedule and such change in the Schedule directly results in any Station Costs exceeding the amount set forth in the Station Budget, then Station Costs shall include such costs in excess of the Station Budget to the extent directly attributable to the Schedule change. The Station Budget for each calendar year, together with such backup information requested by AWA, shall be prepared and provided to AWA by Mesa on or before October 1 of the prior calendar year. The Station Budget shall be based on Mesa’s commercially reasonable estimate of the actual costs that are to be incurred during the next calendar year. If AWA does not approve the Station Budget for any station, then AWA may convert such station to an AWA Service Location pursuant to Section 2.3.

Mesa Guaranteed Costs. AWA, in accordance with Section 7.5, shall pay to Mesa:

the lesser of: (i) the actual costs and expenses associated with certain of the Flight Services and Other Services (the “Guaranteed Non-Maintenance Costs”) set forth in the cost and expense categories set forth in Exhibit C, attached hereto (the “Guaranteed Non-Maintenance Costs Schedule”), or (ii) the amounts set forth in the Guaranteed Non-Maintenance Costs Schedule for each cost and expense category set forth in Exhibit C, attached hereto (the “Guaranteed Non-Maintenance Costs Caps”); and

an amount for maintenance costs and expenses equal to the amounts set forth on Exhibit D (the “Guaranteed Maintenance Costs”).

Contract Negotiation. AWA may assist Mesa in the negotiation of contracts for the provision of materials or services subject to the Actual Costs, Guaranteed Non-Maintenance Costs and Guaranteed Maintenance Costs provided Mesa is not subject to an existing contract for such services or materials.

Guaranteed Costs Adjustment.

CPI Adjustment. For the purposes of calculating CPI increases in Guaranteed Non-Maintenance Costs Caps, increases in the Guaranteed Maintenance Costs, increases in bonuses or penalties pursuant to Section 5 or increases in the base EAS Subsidies pursuant to Section 7.7 the following definitions and formulas shall be applied:

Definition. “CPI” shall mean the Consumer Price Index, U.S. City Average, Urban Wage Earners and Clerical Workers, All Items (base index year 1982-84 = 100) as published by the United States Department of Labor, Bureau of Labor Statistics. If the manner in which the Consumer Price Index as determined by the Bureau of Labor Statistics shall be substantially revised, including, without limitation, a change in the base index year, an adjustment shall be made by the parties in such revised index which would produce results equivalent, as nearly as possible, to those which would have been obtained if such Consumer Price Index had not been so revised. If the Consumer Price Index shall become unavailable to the public because publication is not readily available to enable the parties to make the adjustment referred to in this Section, then the parties shall mutually agree to substitute therefor a comparable index based upon changes in the cost of living or purchasing power of the consumer dollar published by any other governmental agency or, if no such index shall be available, then a comparable index published by a major bank or other financial institution or by a university or a recognized financial publication.

Adjustment Formula. On each anniversary of the Contract Date (each an “Adjustment Date”), to determine the amount of adjustment or increase based on CPI, the applicable Guaranteed Non-Maintenance Costs Caps, the Guaranteed Maintenance Costs, bonuses or penalties and EAS Subsidies, as applicable, in effect for the prior year, shall be adjusted by multiplying the Guaranteed Non-Maintenance Costs Caps on the Guaranteed Non-Maintenance Costs Schedule, the Guaranteed Maintenance Costs, bonuses or penalties and EAS Subsidies, as applicable, in effect for the prior

year, by a fraction, the numerator which shall be the CPI for the third full calendar month immediately preceding the Adjustment Date, and the denominator of which shall be the CPI for the same calendar month in the immediately preceding calendar year (the “Adjustment”).

Governmental Requirements. If any governmental rule, order, regulation or requirement affecting: (i) all aircraft similarly equipped as the Aircraft in any Subfleet (not just those owned by Mesa); or (ii) all airlines flying similar equipment as the Aircraft (not just Mesa), results in an increase in any of the Guaranteed Non-Maintenance Costs or Guaranteed Maintenance Costs such that the actual Guaranteed Non-Maintenance Costs or Guaranteed Maintenance Costs will exceed the then applicable Guaranteed Non-Maintenance Costs Cap or amounts set forth on Exhibit D for the Guaranteed Maintenance Costs, then the applicable Guaranteed Non-Maintenance Costs Cap or Guaranteed Maintenance Costs shall be increased by such amount, as of the effective date of such governmental regulation, rule, order or requirement.

Amendment. Mesa and AWA shall execute an amendment to Exhibit C and Exhibit D within 10 days after each adjustment occurs pursuant to this Section 7.4. The failure to execute such an amendment shall not affect the effectiveness of any adjustment or the bases for any subsequent adjustment. Each adjusted Guaranteed Non-Maintenance Costs Cap and Guaranteed Maintenance Costs shall be effective until the next adjustment of such Guaranteed Non-Maintenance Costs Cap and Guaranteed Maintenance Costs pursuant to this Section 7.4.

Guaranteed Maintenance Costs Reconciliation. Within 180 days after the expiration or termination of this Agreement, AWA, by written notice to Mesa, may review and audit Mesa’s records and files relevant to the actual maintenance costs paid by Mesa in the categories set forth on Exhibit D. If AWA’s review of the records and files reveals that the actual maintenance costs paid by Mesa during the term of this Agreement was less than the sum of all the Guaranteed Maintenance Costs paid by AWA during the term of this Agreement (the “Excess Maintenance Payments”), then Mesa, within 30 days after receipt of written demand, shall pay to AWA an amount equal to the Excess Maintenance Payments. The terms and conditions of this Section shall survive the termination or expiration of this Agreement. Mesa shall maintain and retain all maintenance cost and expense records and files for the entire Term of this Agreement and for at least one year after the expiration or termination of this Agreement.

Payment of Actual and Guaranteed Non-Maintenance Costs.

Estimates. AWA shall pay to Mesa the estimated Actual Costs, Guaranteed Non-Maintenance Costs (using the Guaranteed Maintenance Costs Caps) and Guaranteed Maintenance Costs for each calendar month based on a [***] FCF (the “Estimated Costs”) as follows: By the 20th day of each calendar month, Mesa shall provide AWA with a good faith statement of the Estimated Costs for the following calendar month. On or before the 7^th, 14^th, 21^st and 28^th day of each calendar month (or next business day thereafter if any such dates is other than a business day), AWA shall pay [***]% of the Estimated Costs for such calendar month.

Monthly Reconciliation. On or before the 120^th day after the last day of each calendar month, Mesa shall submit to AWA a statement of the actual Guaranteed Non-Maintenance Costs (using for each monthly statement the applicable Guaranteed Non-Maintenance Costs Caps), the Guaranteed Maintenance Costs and Actual Costs incurred by Mesa (the “Incurred Costs”) and payable by AWA for such calendar month (the “Incurred Costs Statement”). If the Estimated Costs paid by AWA in any calendar month exceed the Incurred Costs in any calendar month, then Mesa, together with the Incurred Costs Statement for such calendar month, shall reimburse AWA the amount by which the Estimated Costs paid by AWA exceeded the Incurred Costs. If the Incurred Costs in any calendar month exceed the Estimated Costs paid by AWA in any calendar month, then AWA, subject to the rights and procedures set forth in Section 7.8, within 45 days after receipt of the Incurred Costs Statement, shall reimburse and pay to Mesa the amount by which the Incurred Costs exceed the Estimated Costs paid by AWA for the subject calendar month.

Annual Reconciliation. At any time within 120 days after the expiration of each Contract Year (as defined below), AWA, upon 2 Business Days prior written notice to Mesa, may review and audit, or cause its independent accountants to review and audit, all records and files (including computer databases) maintained by Mesa and relevant to the calculation of the actual Guaranteed Non-Maintenance Costs incurred by Mesa during the prior Contract Year (the “GNMC Audit”). If the GNMC Audit reveals that the actual Guaranteed Non-Maintenance Costs actually paid by Mesa during the prior Contract Year was less than the sum of all the Guaranteed Non-Maintenance Costs Caps paid by AWA during such Contract Year (the “Excess Non-Maintenance Payments”), then Mesa, within 30 days after receipt of written demand from AWA, shall pay AWA an amount equal to the Excess Non-Maintenance Payment. If Mesa does not pay the Excess Non-Maintenance Payments to AWA timely, then AWA shall have the setoff rights contained in Section 7.9 below. For the purposes of this

section, “Contract Year” means each one year period commencing on April 1 of each calendar year and expiring on March 31 of the next calendar year. For the purposes of the first “Contract Year”, the year shall commence on the Contract Date and expire on March 31, 2002. For purposes of the last Contract Year, the Contract Year shall commence on April 1 and expire on the Expiration Date. For the purpose of determining the actual Guaranteed Non-Maintenance Costs incurred in providing the Flight Services and Other Services, Guaranteed Non-Maintenance Costs subject to allocation to the Flight Services and Other Services shall be allocated to this Agreement by Mesa using the same methodology used by Mesa in establishing the Guaranteed Non-Maintenance Costs Caps.

Finality. The Incurred Costs Statement issued by Mesa shall include all and be the final statement for the Guaranteed Non-Maintenance Costs and Actual Costs payable by AWA for the period covered by each Incurred Costs Statement. AWA shall not be obligated to pay any Guaranteed Non-Maintenance Costs or Actual Costs for a period that are not included in the applicable Incurred Costs Statement when initially issued by Mesa to AWA.

Revenue Sharing. Commencing in the first calendar month after the month in which the Effective Date occurs, AWA shall pay to Mesa, by the 20^th day of each calendar month, an amount equal to the product obtained by multiplying the Segment Revenue Percentage by the Segment Revenue generated during the prior calendar month. For purposes of this Agreement, the following terms have the following definitions:

Aircraft

Segment Revenue Percentage

Beech 1900

Dash 8

CRJ Model 200

CRJ Model 700

CRJ Model 900

Subsidies. Mesa, within 30 days after receipt, shall rebate to AWA all EAS subsidies paid to Mesa by any governmental entities for Flights (the “EAS Subsidies”). Notwithstanding the foregoing to the contrary, if Mesa causes any EAS Subsidies to be increased to an amount in excess of the EAS Subsidies in effect on the Contract Date, increased annually on the anniversary of each Contract Date by an amount equal to an increase in the CPI as calculated pursuant to Section 7.4.1, then AWA shall pay to Mesa [***]% of any such increase within 30 days after receipt of written demand. AWA shall not be responsible to the DOT for continuing service in any EAS market. Notwithstanding the foregoing, if AWA directs Mesa to bid to provide flight service to any EAS market, then AWA shall be responsible for all liabilities incurred in connection with discontinuing such service prior to the expiration of any DOT hold-in order. AWA shall be entitled to retain all payments, subsidies, revenue guarantees or other similar payments generated from the Flight Services flown under this Agreement and negotiated by AWA.

Records, Statements and Audit Rights. Mesa shall maintain separate accounting books and records for the Flight Services and Other Services performed by Mesa under this Agreement. All Incurred Costs Statements and other requests for payment made by Mesa pursuant to this Section 7 shall be accompanied by such supporting information, documentation and calculations described on Exhibit E, attached hereto, and as AWA may reasonably request from time to time (the “Backup Information”). If AWA disputes the amount set forth in any statement or the Backup Information is inadequate, incomplete or inaccurate, then AWA shall pay the undisputed portion of such statement and the portions for which the Backup Information is adequate, complete and accurate, timely, and together with such payment provide Mesa with a written statement of any disputed amount and the amounts for which the Backup Information is inadequate, incomplete or inaccurate. AWA and Mesa shall meet and confer to resolve any disputed amount and inadequate, incomplete or inaccurate Backup Information within 30 days after AWA provides notice of the dispute. Disputed amounts and amounts for which the Backup Information is inadequate, incomplete or inaccurate shall not be payable until the dispute is resolved and then shall be payable within 10 days after the dispute is resolved.

Setoff. All undisputed sums payable by Mesa to AWA pursuant to this Agreement may, at AWA’s election, be setoff against amounts next due by AWA to Mesa pursuant to this Agreement.

Term and Termination.

Term. The term of this Agreement (the “Term”) commences on the Effective Date retroactive to the Contract Date (the “Commencement Date”) and shall expire (“Expiration Date”) on the 8th anniversary of the date that the last CRJ Aircraft is added to the Fleet pursuant to Section 2.2.2 of the Agreement (the “Last Delivery Date”), unless earlier terminated as provided in this Agreement. AWA, by written notice to Mesa at least 180 days prior to the Expiration Date, may extend the Expiration Date to the 10^th anniversary of the Last Delivery Date.

Early Termination. If: (i) Mesa’s OTP Rate for the Phoenix Hub falls below AWA’s OTP Rate for the Phoenix Hub for five of any six calendar months or (ii) Mesa’s FCF for the Phoenix Hub falls below [***]% for five of any of six consecutive calendar months (each, a “Cancellation Event”), AWA, at its election, may by written notice (a “Performance Notice”) inform Mesa that if the Cancellation Event is not cured within one hundred twenty (120) days from receipt of such Performance Notice (the “Cure Period”), AWA, at its option may give a Termination Notice (as defined below). If the Cancellation Event relates to Mesa’s OTP Rate, the cure shall be effected by Mesa bringing its OTP Rate for such Hub to a rate that is equal to or above AWA’s OTP Rate at the Phoenix Hub during the Cure Period. If the Cancellation Event relates to the Mesa’s FCF for the Phoenix Hub, the cure shall be effected by Mesa bringing its FCF at the Phoenix Hub to [***]% or higher during the Cure Period. If, after the Cure Period has expired and Mesa has not cured the Cancellation Event as set forth above, then AWA at any time during the thirty (30) day period following the lapse of the Cure Period without cure may, upon 90 days’ prior written notice to Mesa (“Termination Notice”), terminate this Agreement. Such termination right shall be in addition to any penalty payments set forth in Section 5 and termination rights for an Event of Default pursuant to Section 13.

Change of Control. This Agreement may be terminated by either AWA or Mesa providing the other party with at least 90 days’ prior written notice (the “Change Termination Notice”) in the event of a change of control of the other party or a sale of substantially all of the other party’s assets. “Change of Control” means any “person” or “group” (each as used in Sections 13(d)(3) and 14(d)(2) of the Exchange Act) either becomes the beneficial owner (as defined in Rule 13d-3 of

the Exchange Act), directly or indirectly, of voting securities of either party (or securities converted into or exchangeable for such voting securities) representing 50% or more of the combined voting power of all voting securities of the party (on a fully diluted basis) or otherwise has the ability, directly or indirectly, to elect a majority of the board of directors of the party or any person or two or more persons acting in concert shall have acquired by contract or otherwise, or shall have entered into a contract or arrangement that, upon consummation thereof, will result in its or their acquisition of the power to exercise, directly or indirectly, a controlling influence on the management or policies of the party.

Effect of Termination. If AWA elects to terminate this Agreement pursuant to this Section 8, AWA, in the Termination Notice, shall establish as the termination date any date between 90 and 180 days after delivery of the Termination Notice or Change Termination Notice, as applicable. Mesa shall continue to provide the Flight Services and Other Services required by this Agreement until the termination date set forth in the Termination Notice or Change Termination Notice, as applicable. AWA and Mesa shall make all payments as required by this Agreement for the period through and including the termination date set forth in the Termination Notice or Change Termination Notice, as applicable.

Service ▇▇▇▇ License For Services Provided By Mesa.

Grant of License. For the payment of $1.00, AWA hereby grants to Mesa a non-exclusive, non-transferable license to use such AWA Service Marks as AWA may designate, in writing, from time to time in connection with the Flight Services and Other Services to be rendered by Mesa; provided, however, that at any time prior to expiration or termination of this Agreement AWA may alter, amend or revoke the license hereby granted and require Mesa’s use of any new or different AWA Service ▇▇▇▇ in conjunction with the Flight Services and Other Services provided hereunder as AWA may determine in its sole discretion and judgment.

Operation under AWA Service Marks/Aircraft Decor. Mesa, at its expense (subject to reimbursement in the next sentence), shall cause the Fleet and any replacement or additional Aircraft utilized by Mesa, or any of the Affiliated Service Providers, to provide the Flight Services, to be painted, marked and decorated to bear AWA Service Marks, consisting of AWA aircraft exterior and interior color decor and pattern provided by AWA and the name “America West Express.” AWA shall reimburse Mesa for 50% of the costs of painting, decorating or marking any new CRJ added to the Fleet pursuant to Section 2.2. Upon written notice from AWA, which shall include the specifications for any such changes in AWA Service Marks and exterior or interior aircraft decor and patterns, Mesa shall effect changes in the aircraft decor and patterns within 12 months from the date of such notice. AWA shall reimburse Mesa for the cost of repainting the Fleet in the event that AWA changes its logo and color decor and pattern from the design existing as of the Effective Date. Mesa shall use and display suitable signs on the interior and exterior of each Aircraft identifying Mesa as the operator of the Services, such signs shall be subject to the prior written consent of AWA as to

nature, size and location provided that the signs shall comply with all Regulations. AWA shall reimburse Mesa for the actual costs and expenses of repainting any Aircraft eliminated from the Fleet pursuant to Section 2.2. All announcements, displays or literature used or viewed by Mesa customers on Flights shall highlight “America West Express.” No such announcements, displays or literature shall reference “Mesa Airlines,” other than to identify Mesa or the operator of the Services, on briefing cards or as required by the Regulations.

Terms and Conditions Governing Service ▇▇▇▇ License.

Mesa hereby acknowledges AWA’s ownership of the AWA Service Marks, further acknowledges the validity of the AWA Service Marks, and agrees that it shall not do anything in any way to infringe or abridge upon AWA’s rights in the AWA Service Marks or directly or indirectly to challenge the validity of the AWA Service Marks.

To assure that the production, appearance and quality of the AWA Service Marks is consistent with AWA’s reputation for high quality and the goodwill associated with the AWA Service Marks, Mesa agrees to maintain a level of quality consistent with AWA’s quality in the Flight Services and Other Services it provides pursuant to this Agreement and to follow AWA’s written instructions regarding use of AWA’s Service Marks, as they may be amended from time to time.

The person or entity claiming indemnification hereunder is referred to as the “Indemnified Party” and the party against whom such claims are asserted hereunder is referred to as the “Indemnifying Party”. Each Indemnified Party shall give reasonably prompt notice to the Indemnifying Party of any action or proceeding or assertion or threat of claim commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify the Indemnifying Party (i) shall not relieve the Indemnifying Party from any liability which it may have under the indemnity agreement provided in this Agreement, unless and to the extent it did not otherwise learn of such action, threat or claim and the lack of notice by the Indemnified Party results in the forfeiture by the Indemnifying Party of substantial rights and defenses and (ii) shall not, in any event, relieve the Indemnifying Party from any obligations to the Indemnified Party other than the indemnification obligation provided under Sections 10.2 and 10.3 above. If the Indemnifying Party elects within a reasonable time after receipt of notice, the

Indemnifying Party may assume the defense of the action or proceeding at Indemnifying Party’s own expense with counsel chosen by the Indemnifying Party and approved by the Indemnified Party; provided, however, that, if the Indemnified Party reasonably determines upon advice of counsel that a conflict of interest exists where it is advisable for the Indemnified Party to be represented by separate counsel or that, upon advice of counsel, there may be legal defenses available to it which are different from or in addition to those available to the Indemnifying Party, then the Indemnified Party shall be entitled to separate counsel at the Indemnifying Party’s expense, which counsel shall be chosen by the Indemnified Party in its sole discretion. If the Indemnifying Party does not assume the defense, after having received the notice referred to in the second sentence of this Section, the Indemnifying Party will pay the reasonable fees and expenses of counsel for the Indemnified Party. Unless and until a final judgment that an Indemnified Party is not entitled to the costs of defense under the foregoing provision, the Indemnifying Party shall reimburse, promptly as they are incurred, the Indemnified Party’s costs of defense. The Indemnifying Party shall not settle or compromise any claim for which an Indemnified Party is entitled to indemnity without the prior written consent of the Indemnified Party.

Insurance.

Mesa, at all times during the Term of this Agreement, shall have and maintain and shall cause the Affiliated Service Providers to have and maintain in full force and effect, policies of insurance satisfactory to AWA, of the types of coverage, and in the minimum amounts stated below with insurance companies satisfactory to AWA and under terms and conditions satisfactory to AWA, including insurance coverage on all Aircraft used to provide Flight Services. Unless otherwise specified, the minimum amounts of insurance coverage required hereunder shall be per occurrence, combined single limit for all insurance coverage required hereunder.

The parties hereby agree that from time to time during the Term of this Agreement, AWA may require Mesa and the Affiliated Service Providers to have and maintain amounts of insurance coverage different from those amounts set forth in Section 10.5.1, should AWA, in its reasonable judgment, deem the circumstances and conditions of the Flight Services and Other Services to require increases in any or all of the foregoing minimum insurance coverages.

Mesa shall cause all policies of insurance which it and the Affiliated Service Providers maintain pursuant to this Agreement, to be duly and properly endorsed by Mesa’s and the Affiliated Service Providers’ insurance underwriters as follows:

To provide that any waiver of rights of subrogation against other parties by Mesa or the Affiliated Service Providers shall not affect the coverage provided hereunder with respect to AWA.

To provide that Mesa’s and the Affiliated Service Providers’ underwriters shall waive any and all subrogation rights against AWA, its directors, officers, agents and employees without regard to any breach of warranty by Mesa or the Affiliated Service Providers or to provide other evidence of such waiver of recourse against AWA, its

directors, officers, agents, or employees as shall be acceptable to AWA. Be duly and properly endorsed to

provide that each such policy or policies or any part or parts thereof shall not be canceled, terminated, or materially altered, changed or amended by Mesa’s and the Affiliated Service Providers’ insurance underwriters, until after 30 days’ written notice to AWA which 30 days’ written notice shall commence to run from the date such notice is actually received by AWA.

With respect to policies of insurance described as Aircraft Liability and Ground Liability Insurance, Mesa will provide that Mesa’s and the Affiliated Service Providers’ policies:

Endorse AWA, its directors, officers, agents, parents, subsidiaries and employees as Additional Insureds thereunder.

Constitute primary insurance for such claims and acknowledge that any other insurance policy or policies of AWA will be secondary or excess insurance;

Cover AWA’s costs of defending against such insured claims including, without limitation, to the extent permitted by the policies, costs incurred in the retention of separate legal counsel of its choice; and

Provide a cross-liability clause acceptable to AWA, and a specific contractual liability insurance provision covering liability assumed by Mesa and the Affiliated Service Providers under this Agreement.

With respect to policies of insurance for coverage described as Aircraft Liability and Ground Liability Insurance and All Risk Hull Insurance, Mesa shall cause its insurance underwriters to provide a breach of warranty clause.

All aircraft hull insurance provided pursuant to this Agreement shall be provided on agreed value basis and, except with the consent of AWA,, shall not be subject to more than the standard market deductibles. In the event of loss, settled on the basis of a total loss, all losses shall be payable in full.

Upon request by AWA, Mesa shall furnish to AWA evidence satisfactory to AWA of the aforesaid insurance coverage and endorsements, including certificates certifying that the aforesaid insurance policy or policies with the aforesaid policy limits are duly and properly endorsed as aforesaid and are in full force and effect.

With respect to policies of insurance obtained directly from foreign underwriters, Mesa shall cause such insurance underwriters to provide that AWA may maintain against Mesa’s and the Affiliated Service Providers’ underwriters a direct action in the United States upon such insurance policies and to this end to provide a standard service of suit clause designating an agent for service of process in the United States of America.

In the event Mesa or the Affiliated Service Providers fails to maintain in full force and effect any of the insurance and endorsements described in Section 10.5, AWA shall have the right (but not the obligation) to procure and maintain such insurance or any part thereof. The cost of such insurance shall be payable by Mesa to AWA upon demand by AWA. The procurement of such insurance or any part thereof by AWA shall not discharge or excuse Mesa’s or the Affiliated Service Providers‘ obligation to comply with the provisions of Section 10.5. Mesa agrees not to cancel, terminate or materially alter, change or amend any of the policies referred to in Section 10.5 without 30 days’ prior written notice to AWA of its intent to cancel, terminate or materially alter, change or amend said policies or insurance which 30 day notice period shall commence to run from the date notice is actually received by AWA.

AWA shall maintain cargo liability coverage, in types and amounts required by law, for all air freight transported by Mesa or the Affiliated Service Providers under an AWA airbill on any Flights.
