1.       Rights, Responsibilities and Obligations of Mesa:

         1.1      Flight Service. During the term of this Agreement, Mesa shall
                  operate America West Express air transportation services (the
                  "Flight Services"), using the fleet of aircraft as set forth
                  in Section 1.2, to and from the cities and based upon the
                  schedule [CONFIDENTIAL PORTION DELETED AND FILED SEPARATELY
                  WITH THE SECURITIES AND EXCHANGE COMMISSION] (the "Schedule")
                  in written notice to Mesa (a "Schedule Notice"). For purposes
                  of this Agreement, "Flights" means flights operated pursuant
                  to the Schedule. [CONFIDENTIAL PORTION DELETED AND FILED

                  COMMISSION] When creating a Schedule, AWA shall: (i) take into
                  account Mesa's aircraft maintenance requirements; (ii) create
                  a Schedule which will permit Mesa to schedule flight crews in
                  a manner consistent with industry operational practices; (iii)
                  schedule block times based on AWA's internal block time
                  policy; (iv) provide for a reasonable time on the ground for
                  Aircraft between arrivals and departures; (v) take into
                  account airport facilities available for Aircraft handling;
                  and (vi) provide for scheduled heavy maintenance on Aircraft
                  as required from time to time. Mesa shall implement all
                  changes in the Schedule contained in a Schedule Notice in
                  accordance with AWA's scheduling requirements but in no event
                  [CONFIDENTIAL PORTION DELETED AND FILED SEPARATELY WITH THE
                  SECURITIES AND EXCHANGE COMMISSION] after receipt of a
                  Schedule Notice. Mesa or any of its affiliates shall not
                  provide any flight service for any other airline for flights
                  that originate in or end in Phoenix, Arizona, except that Mesa
                  may provide such flight service for itself on all essential
                  air service ("EAS") routes that AWA removes from the Schedule.

                  Mesa acknowledges that AWA may Schedule Flights using CRJs in
                  and out of the Columbus, Ohio airport. If such Flights are
                  Scheduled, Mesa and AWA, in good faith based on prevailing
                  market costs and expenses, shall adjust the Guaranteed Costs
                  payable pursuant to Paragraph 6.2 to take into consideration
                  the increased cost of operating such Flights in such location.
                  If the Guaranteed Costs are adjusted, then AWA and Mesa shall
                  execute and attach an addendum to this Agreement supplementing
                  the Guaranteed Costs Schedule.

                  1.2.5    Elimination of Beech 1900s. Notwithstanding the

                           [CONFIDENTIAL PORTION DELETED AND FILED SEPARATELY
                           WITH THE SECURITIES AND EXCHANGE COMMISSION] after
                           Effective Date (the "Elimination Notice"), may
                           require Mesa to reduce the Subfleet of Beech 1900s to
                           [CONFIDENTIAL PORTION DELETED AND FILED SEPARATELY
                           WITH THE SECURITIES AND EXCHANGE COMMISSION] on the

                           this Agreement, then AWA and Mesa shall attempt to
                           negotiate a code share agreement to provide service
                           to the destinations serviced by the Beech 1900s on

                           (the "Beech Code Agreement"). If AWA and Mesa are
                           unable to reach an agreement on the terms and
                           conditions of the Beech Code Agreement within

                           AWA provides the Elimination Notice, then AWA may
                           enter into an agreement with any other flight service
                           provider to provide flight services to such

                           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

                  8.3.3    Mesa agrees that, in providing the Flight Services

                           written consent of AWA. AWA shall have absolute
                           discretion to withhold its consent concerning any and
                           all such advertising and use of the AWA Service Marks
                           in any advertising by Mesa. In the event AWA approves
                           the use of such AWA Service Marks in any advertising,
                           such advertising shall identify AWA as the owner of
                           such Service Marks and conform with any additional
                           requirements specified by AWA.

                  8.3.4    To the extent that Mesa is licensed to use the AWA
                           Service Marks, the AWA Service Marks shall be used
                           only in connection with the Flight Services and Other
                           Services specifically covered by this Agreement and
                           not in connection with any other business or activity
                           of Mesa or any other entity.

                  8.3.5    Nothing in this Agreement shall be construed to give
                           Mesa the exclusive right to use the AWA Service Marks
                           or abridge AWA's right to use and license the AWA
                           Service Marks, and AWA hereby reserves the right to
                           continue to use the AWA Service Marks and to license
                           such other uses of the AWA Service Marks as AWA may
                           desire.

                  8.3.6    No term or provision of this Agreement shall be
                           construed to preclude the use of the AWA Service
                           Marks, including "America West Express," or the

                  control over its operations or the conduct of its business as

                  Market (except as specified in Section 6.7); and (vii) failure

                  any other expenses reasonably incurred in investigating,
                  preparing or defending against any claim or action arising out
                  of or relating to any of the foregoing.

         9.3      Indemnification by AWA. AWA agrees to indemnify, defend and
                  hold harmless Mesa, its directors, officers, employees,
                  agents, parent corporation, subsidiaries and affiliates for,
                  from and against any and all Damages, as incurred, arising out
                  of, resulting from or incurred in connection with: (i) AWA's
                  breach of this Agreement; (ii) damage or destruction of
                  property of any person, or injury or death of any person,
                  caused by, arising out of, or in





                                       26



   27



                  connection with any act or omission of AWA, its employees,
                  agents, licensees, contractors, suppliers, officers or
                  directors in performing AWA's obligations under this
                  Agreement; and (iii) any taxes, impositions, assessments or
                  other governmental charges incurred by AWA for revenue
                  received by AWA under this Agreement. AWA shall reimburse Mesa
                  or other Indemnified Party (as defined below) for any legal
                  and any other expenses reasonably incurred in investigating,
                  preparing or defending against any claim or action arising out
                  of or relating to any of the foregoing.

         9.4      Conduct of Indemnification Proceedings. 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 9.2 and 9.3 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
                  paragraph, 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.

                           in Section 9.5.1, should AWA, in its reasonable
                           judgment, deem the circumstances and conditions of
                           the Flight Services and Other Services to require

                  treated as confidential and shall not be disclosed to third
                  parties without the express written consent of AWA and Mesa,
                  or as required by law. In the event of disclosure required by
                  law, only those portions of this Agreement required to be
                  disclosed shall be disclosed. The disclosing party shall make
                  good faith efforts to minimize the portions to be disclosed
                  and shall seek confidential treatment by the receiving party
                  or agency for any portions disclosed. In the event of one
                  party being served a subpoena or discovery request, prior to
                  responding to the subpoena or request, the party served shall
                  notify the other party to provide the other party an
                  opportunity to contest the disclosure of any terms of this
                  Agreement.

                  provided by either party to the other party, except for
                  information generally available to the public. AWA and Mesa
                  agree that they shall maintain all Confidential Information in
                  confidence and use such Confidential Information solely for
                  purposes of performance under this Agreement. Such
                  Confidential Information shall be distributed within each
                  party's company only to personnel and to its legal counsel,
                  auditors and other consultants on a need-to-know basis for
                  purposes related to this Agreement or in compliance with a
                  court order or statutory or regulatory requirements. Except
                  for legal counsel and auditors, and as permitted by Section
                  10.1, in no event shall either party disclose Confidential
                  Information to any third parties except

                  approved by both parties in writing in advance of such
                  disclosure. Confidential Information does not include
                  information that is available to the general public other than
                  as a result of disclosure by the disclosing party or
                  information that was known or independently developed by the
                  receiving party prior to disclosure, as evidenced by records
                  kept in the ordinary course of business.

         10.3     Mesa acknowledges and agrees that any Confidential Information
                  shared or given to AWA pursuant to this Agreement may be
