                                                 .

4.1.2    The base price of the Buyer Selected Optional Features is
                         [CONFIDENTIAL PORTION DELETED]

         Date to reflect economic fluctuations during the period from February
         1, 1995 to the Delivery Date of each Aircraft. Such adjustments shall
         be based on the formula attached as Appendix I.

4.2.2    As the Aircraft Purchase Price cannot be established at this time due
         to the effect of price escalation, an estimated delivery price has been

         including, but not limited to, sales, use, value added (including the
         Canadian Goods and Services Tax), personal property, gross receipts,
         franchise, excise taxes, assessments or duties, (hereafter "Taxes")
         which are or may be imposed by law upon BRAD, any affiliate of BRAD,
         Buyer or the Aircraft whether or not there is an obligation for BRAD to
         collect same from Buyer, by any taxing authority or jurisdiction
         occasioned by, relating to or as a result of the sale, lease, delivery,
         storage, use or other consumption of any Aircraft, BFE or any other
         matter, good or service provided under or in connection with this
         Agreement. According to current legislation, Canadian taxes, duties and
         Goods and Services Tax are not applicable to aircraft sold and
         immediately exported from Canada.

4.4      If any Taxes (other than Canadian income taxes charged on the income of
         BRAD) are imposed upon Buyer or become due or are to be collected from
         BRAD by any taxing authority, that may result from execution of this
         Agreement,

4.5      Upon BRAD's request, Buyer shall execute and deliver to BRAD any
         documents that BRAD deems necessary or desirable in connection with any
         exemption from or reduction of or the contestation of or the defence

                     operation and availability of test equipment or special
                     tools;

                f.
                         [CONFIDENTIAL PORTION DELETED]



7.4      If at any time between receipt of the BFE by BRAD and the Delivery
         Date, it is determined by BRAD that an item of BFE supplied does not
         meet the standards and requirements described above or its fitment,
         integration and testing in the Aircraft or 

   17

         Aircraft systems create delays in the manufacturing or certification
         process, then such BFE may be removed and replaced by other BFE or by
         BRAD's equipment.

                         [CONFIDENTIAL PORTION DELETED]
                                              .

7.5      In the event that the Scheduled Delivery Date is delayed due to any
         delay caused by Buyer's failure to: 

                    a.  deliver, or have BFE delivered by the date required;

                    b.  ensure satisfactory design, suitability, use or 
                        operation of the BFE;

                    c.  furnish or obtain applicable BFE data;

                    d.  perform any adjusting, calibrating, retesting or
                        updating of BFE;

                    e.  furnish or obtain any approvals in compliance with the
                        provisions of this Article; or

                    f.  comply with the conditions of this Article.

         BRAD agrees to discuss with Buyer on the steps to be taken to minimize,
         cure, eliminate or work around the delay
                         [CONFIDENTIAL PORTION DELETED]
                                                                .

7.6      Should there be a delay caused by an event to which reference is made
         in Article 13.0 in connection with the BFE and if such delay cannot
         reasonably be minimized, cured, eliminated or worked around by
         agreement of the parties,
                         [CONFIDENTIAL PORTION DELETED]

                                                     .

7.7      If this Agreement is terminated in whole or in part in accordance with
         the provisions thereof BRAD may elect to, by written notice to Buyer,
         either:

                    a.  purchase the BFE ordered by Buyer and/or received by
                        BRAD at the invoice price paid by Buyer; or
   18
                          
                    b.  return the BFE to Buyer FOB BRAD's plant, or such other
                        place that BRAD may designate.

ARTICLE 8 - CERTIFICATION

8.1      BRAD has obtained from Transport Canada, the Canadian Department of
         Transportation ("DOT"), a DOT Type Approval (Transport Category) and
         will obtain from the Federal Aviation Administration of the United
         States ("FAA") an FAA Type Certificate for the type of aircraft
         purchased under this Agreement.

8.2      BRAD shall provide to Buyer a DOT Certificate of Airworthiness For
         Export (Transport Category) on or before the Delivery Date.

         BRAD shall, to the extent permitted by law, and with Buyer's
         assistance, seek the issuance of a Canadian export licence to enable
         Buyer to export the Aircraft from Canada subject to prevailing export
         control regulations in effect on the Delivery Date.

8.4      If any addition or change to, or modification or testing of the
         Aircraft is required by any law or governmental regulation or
         requirement or interpretation thereof by any governmental agency having
         jurisdiction in order to meet the requirements of Article 8.2, (a
         "Regulatory Change") such Regulatory Change shall be made to the
         Aircraft prior to Delivery Date, or at such other time after the
         Delivery Date as the parties may agree upon.

8.5      The Regulatory Change shall be made without additional charge to Buyer
         unless such Regulatory Change is:

         (a)    necessary to comply with any requirement of the United States,
                the country of import, which varies from or is in addition to
                its requirements in effect on the date hereof for the issuance
                of a Certificate of Airworthiness, in which case Buyer shall pay
                BRAD's reasonable charges for such Regulatory Change, or

         (b)    required by any governmental law or regulations or
                interpretation thereof promulgated by DOT or the FAA which is
                effective subsequent to the date of this Agreement but before
                the Delivery Date and is applicable to all aircraft in general
                or to all aircraft of the same category as the Aircraft, in
                which case Buyer shall pay BRAD's reasonable charges for such
                Regulatory Change incorporated in any such Aircraft.
   20

8.6      If delivery of the Aircraft is delayed by the incorporation of any
         Regulatory Change, such delay shall be an Excusable Delay within the
         meaning of Article 13.

8.7      BRAD shall issue a Change Order, reflecting any Regulatory Change
         required to be made under this Article 8, which shall set forth in
         detail the particular changes to be made and the effect, if any, of
         such changes on design, guaranteed performance, weight, balance, time
         of delivery, Base Price and estimated Purchase Price. Any Change Orders
         issued pursuant to this Article shall be effective and binding upon the
         date of BRAD's transmittal of such Change Order.

8.8      If the use of any of the certificates identified in this Article 8 are
         discontinued during the performance of this Agreement, reference to
         such discontinued certificate shall be deemed a reference to any other
         certificate or instrument which corresponds to such certificate or, if
         there should not be any such other certificate or instrument, then BRAD
         shall be deemed to have complied with such discontinued Certificate(s)
         upon demonstrating that the Aircraft complies substantially with the
         Specification.


   21

ARTICLE 9 - ACCEPTANCE PROCEDURE

         BRAD's expense. BRAD shall retain care, custody and control over the
         Aircraft.

9.5      If no Aircraft defect or discrepancy is revealed during the inspection
         and/or flight test, Buyer shall accept the Aircraft, on or before the

         promptly be corrected by BRAD, at no cost to Buyer, which correction
         may occur during or after the Acceptance Period depending on the nature
         of the defect or discrepancy and of the time required for correction.
         To the extent necessary to verify such correction, BRAD shall perform
         one (1) or more further acceptance flights.

                         Purchase Price and any other amounts due, at which time
                         BRAD shall cause a bill of sale to be issued (in the
                         form of Exhibit II hereto) passing to Buyer good title
                         to the Aircraft free and clear of all liens, claims,

         Bill of Sale and of the Certificate of Receipt of Aircraft (in the form
         of Exhibit III hereto).

9.8      Provided that BRAD has met all of its obligations under this Article 9,
         should Buyer

         Provided that BRAD has met all of its obligations under this Article 9,
         should Buyer not accept, pay for and/or take delivery of any one of the
         Aircraft
                         [CONFIDENTIAL PORTION DELETED]

               , make arrangements satisfactory to BRAD to accept

         Sale to Buyer on the Delivery Date. Except as provided in Article 9.7
         (c), risk of loss of or damage to the Aircraft passes to Buyer on the
         Delivery Date.

10.2     If, after transfer of title on the Delivery Date, the Aircraft remains
         in or is returned to the care, custody or control of BRAD, Buyer shall

         features or Buyer Furnished Equipment ("BFE"), if any, changing the
         Aircraft from that described in the Specification attached hereto,

         due directly or indirectly to a cause which is beyond the reasonable
         control or without the fault or negligence of BRAD (an "Excusable
         Delay"), BRAD shall not be liable for, nor be deemed to be in default
         under this Agreement on account of such delay in delivery of the
         Aircraft or other performance hereunder and the time fixed or required
         for the performance of any obligation or responsibility in this
         Agreement shall be extended for a period equal to the period during
         which any such cause or the effect thereof persist. Excusable Delay

                thereto, or interpretation thereof, by a governmental agency,
                the effective date of which is subsequent to the date of this
                Agreement, or by reason of any change or addition made by BRAD
                or its affiliates or requested by a governmental agency to the

                interpretation thereof to obtain any such airworthiness approval
                or certificate.

13.2     (a)    If BRAD concludes, based on its appraisal of the facts and
                normal scheduling procedures, that due to Excusable Delay
                delivery of any Aircraft will be delayed for more than nine (9)
                months after the originally Scheduled Delivery Date or any
                revised date agreed to in writing by the parties, BRAD shall
                promptly notify Buyer in writing and either party may then
                terminate this Agreement with respect 
   29

                to such Aircraft by giving written notice to the other within
                fifteen (15) days after receipt by Buyer of BRAD's notice.

                    delayed for more than twelve (12) months after the Scheduled
                    Delivery Date, either party may terminate this Agreement
                    with respect to such Aircraft by giving written notice to
                    the other within fifteen (15) days after the expiration of
                    such twelve (12) month period.

13.3     Termination under Article 13.2 shall discharge all obligations and
         liabilities of Buyer and BRAD hereunder with respect to such delayed
         Aircraft and all related undelivered items and services, except that
         BRAD shall promptly repay to Buyer, and BRAD's sole liability and
         responsibility shall be limited to the repayment to Buyer, of all
         advance payments for such Aircraft received by BRAD

                         [CONFIDENTIAL PORTION DELETED]
                                       , less any amount due by Buyer to BRAD.

13.4     The termination rights set forth in Article 13.2 are in substitution
         for any and all other rights of termination or contract lapse arising
         by operation of law in connection with Excusable Delays.

ARTICLE 14 - NON-EXCUSABLE DELAY

14.1     If delivery of the Aircraft is delayed by causes not excused under
         Article 13.1 (a "Non- Excusable Delay"), BRAD shall pay Buyer,
         [CONFIDENTIAL PORTION DELETED] of Non-Excusable Delay in excess of a
         grace period of [CONFIDENTIAL PORTION DELETED], to a [CONFIDENTIAL
         PORTION DELETED] of [CONFIDENTIAL PORTION DELETED] for any such delayed
         Aircraft.

14.2     [CONFIDENTIAL PORTION DELETED]

14.3     Any right Buyer might otherwise have to refuse to accept delivery of an
         Aircraft when offered by BRAD for inspection and acceptance following a
         Non-Excusable Delay [CONFIDENTIAL PORTION DELETED] will not have the
         right to refuse to take delivery of any Aircraft because of a
         Non-Excusable Delay unless and until the aggregate duration of the
         Non-Excusable Delay for such Aircraft [CONFIDENTIAL PORTION DELETED].
         If BRAD has not offered such Aircraft for inspection and acceptance
         during the Non-Excusable Delay Period, Buyer may [CONFIDENTIAL PORTION
         DELETED]. If, no such notice having been given, BRAD offers such
         Aircraft for inspection and acceptance after the Non-Excusable Delay
         Period and Buyer refuses to take delivery of such Aircraft because of
         Non-Excusable Delay, 
                         [CONFIDENTIAL PORTION DELETED]
         the [CONFIDENTIAL PORTION DELETED] calculated under Article 14.1 to the
         date of termination.  In addition BRAD shall promptly repay to Buyer 
         all advance payments for such Aircraft
                         [CONFIDENTIAL PORTION DELETED]

                                                  .

   31

ARTICLE 15 - LOSS OR DAMAGE

15.1     In the event that prior to the Delivery Date of any of the Aircraft,
         the Aircraft is lost, destroyed or damaged beyond repair due to any
         cause, BRAD shall promptly notify Buyer in writing. Such notice shall
         specify the earliest date reasonably possible, consistent with BRAD's
         other contractual commitments and production schedule, by which BRAD
         estimates it would be able to deliver a replacement for the lost,
         destroyed or damaged Aircraft. This Agreement shall automatically
         terminate as to such Aircraft unless Buyer gives BRAD written notice,
         within thirty (30) days of BRAD's notice, that Buyer desires a
         replacement for such Aircraft. If Buyer gives such notice to BRAD, the
         parties shall execute an amendment to this Agreement which shall set
         forth the Delivery Date for such replacement aircraft and corresponding
         new replacement Aircraft Purchase Price; provided, however, that
         nothing herein shall obligate BRAD to manufacture and deliver such
         replacement aircraft if it would require the reactivation or
         acceleration of its production line for the model of aircraft purchased
         hereunder. The terms and conditions of this Agreement applicable to the
         replaced Aircraft shall apply to the replacement aircraft.

15.2     In the event that one of the first seven Aircraft is lost or damaged,
         as per this section, Buyer may nonetheless return the Dash 8 Series 300
         aircraft leased from BRAD as per the scheduled delivery, and thus
         advance in sequence the one-for one trade-in obligation.


   32

ARTICLE 16  -  TERMINATION

16.1     This Agreement may be terminated, in whole or in part, with respect to
         any or all of the Aircraft before the Delivery Date by BRAD or Buyer by
         notice of termination to the other party upon the occurrence of any of
         the following events:

                (a) a party makes an assignment for the benefit of creditors or
                    admits in writing its inability to pay its debts or
                    generally does not pay its debts as they become due; or

                (b) a receiver or trustee is appointed for a party or for
                    substantially all of such party's assets and, if appointed
                    without such party's consent, such appointment is not
                    discharged or stayed within thirty (30) calendar days
                    thereafter; or 

                (c) proceedings or action under any law relating to bankruptcy,
                    insolvency or the reorganization or relief of debtors are
                    instituted by or against a party, and, if contested by such
                    party, are not dismissed or stayed within thirty (30)
                    calendar days thereafter; or

                (d) 
                         [CONFIDENTIAL PORTION DELETED]

                                                                .

16.2     In addition, this Agreement may be terminated, in whole or in part,
         before the Delivery Date with respect to any or all undelivered
         Aircraft:

                (a) as otherwise provided in this Agreement; or

                (b) if Buyer is in default or breach of any material term or
                    condition of this Agreement and Buyer does not cure such
                    default or breach within forty-five (45) calendar days after
                    receipt of notice from BRAD specifying such default or
                    breach.

16.3     Buyer may terminate this Agreement, in whole or in part, before the
         Delivery Date, with respect to any undelivered Aircraft, if BRAD is in
         default or breach of any material term or condition of this Agreement
         and such breach remains uncured for a period of forty-five (45)
         calendar days following receipt of a notice from Buyer specifying the
         nature of default or breach.


   33

16.4     In case of termination of this Agreement by BRAD pursuant to Articles
         16.1 or 16.2:

         (a)    all rights (including property rights), if any, which Buyer may
                have or may have had in or to this Agreement or any or all of
                the undelivered Aircraft shall become null and void with
                immediate effect;

         (b)    all rights (including property rights and the right to sell the
                Aircraft to another party, if any) in and to any or all of the
                undelivered Aircraft shall be vested with BRAD free and clear of
                any ownership or title rights, if any, liens, charges or
                encumbrances; and

         (c)    all amounts paid by Buyer shall be retained by BRAD and, with
                respect to the applicable undelivered Aircraft, shall be applied
                against the costs, expenses, losses and damages incurred by BRAD
                as a result of Buyer's default and/or the termination of this
                Agreement. Buyer hereby acknowledges and recognizes that BRAD
                shall have all rights permitted by law to recover from Buyer
                such costs, expenses, losses and damages and, in any event, such
                costs, expenses, losses and damages will aggregate not less than

         by Buyer, Buyer's sole rights, remedies and recourses against BRAD and

18.1     In the case of any actual or alleged infringement of any Canadian or
         United States patent or, subject to the conditions and exceptions set
         forth below, any patent issued under the laws of any other country in
         which Buyer from time to time may lawfully operate the Aircraft ("Other
         Patents"), by the Aircraft, or by any system, accessory, equipment or
         part installed in such Aircraft at the time title to such Aircraft
         passes to Buyer, BRAD shall indemnify, protect and hold harmless Buyer
         from and against all claims, suits, actions, liabilities, damages and
         costs resulting from the infringement, excluding any incidental or
         consequential damages (which include without limitation loss of revenue
         or loss of profit) and BRAD shall, at its option and expense:

         (a)    procure for Buyer the right under such patent to use such
                system, accessory, equipment or part; or

         (b)    replace such system, accessory, equipment or part with one of
                the similar nature and quality that is non-infringing; or

         (c)    modify such system, accessory, equipment or part to make same
                non-infringing in a manner such as to keep it otherwise in
                compliance with the requirements of this Agreement.

         BRAD's obligation hereunder shall extend to Other Patents only if from
         the time of design of the Aircraft, system, accessory, equipment or
         part until the alleged infringement claims are resolved:
   36

         (a)    such other country and the country in which the Aircraft is
                permanently registered have ratified and adhered to and are at
                the time of the actual or alleged infringement contracting
                parties to the Chicago Convention on International Civil
                Aviation of December 7, 1944 and are fully entitled to all
                benefits of Article 27 thereof; and

         (b)    such other country and the country of registration shall each
                have been a party to the International Convention for the
                Protection of Industrial Property (Paris Convention) or have
                enacted patent laws which recognize and give adequate protection
                to inventions made by the nationals of other countries which
                have ratified, adhered to and are contracting parties to either
                of the forgoing conventions.

18.2     The foregoing indemnity does not apply to BFE, or to avionics, engines
         or any system, accessory, equipment or part that was not manufactured
         to BRAD's detailed design or to any system, accessory, equipment or
         part manufactured by a third party to BRAD's detailed design without
         BRAD's authorization.

18.3     Buyer's remedy and BRAD's obligation and liability under this Article
         are conditional upon (i) Buyer giving BRAD written notice within ten
         (10) days after Buyer receives notice of a suit or action against Buyer
         alleging infringement or within twenty (20) days after Buyer receives
         any other written claim of infringement (ii) Buyer uses reasonable
         efforts in full cooperation with BRAD to reduce or mitigate any such
         expenses, damages, costs or royalties involved, and (iii) Buyer
         furnishes promptly to BRAD all data, papers and records in its
         possession or control necessary or useful to resist and defend against
         such claim or suit. BRAD may at its option conduct negotiations with
         any party claiming infringement and may intervene in any suit or
         action. Whether or not BRAD intervenes, BRAD shall be entitled at any
         stage of the proceedings to assume or control the defence. Buyer's
         remedy and BRAD's obligation and liability are further conditional
         judgment upon BRAD's prior approval of Buyer's payment or assumption of
         any liabilities, expenses, damages, royalties or costs for which BRAD
         may be held liable or responsible for.

18.4     THE INDEMNITY, OBLIGATIONS AND LIABILITIES OF BRAD AND REMEDIES OF
         BUYER SET OUT IN THIS ARTICLE ARE EXCLUSIVE AND ACCEPTED BY BUYER
         TO BE IN LIEU OF AND IN SUBSTITUTION FOR, AND BUYER HEREBY WAIVES,

Gentlemen:


RE: LETTER AGREEMENT NO. B95-7701-MJR-008   (RE: AIRCRAFT SCHEDULE RELIABILITY
GUARANTEE)


Reference is made to Purchase Agreement No. B95-7701-PA-299 (the "Agreement")
between Bombardier, Inc., represented by its Bombardier Regional Aircraft
Division ("BRAD") and Mesa Airlines, Inc. ("Buyer") for the sale of twenty-five
(25) DHC-8-200 aircraft (the "Aircraft").

This letter, when accepted and agreed to by Buyer contemporaneously with
execution of the Agreement, will become part of the Agreement and will evidence
our further agreement with respect to the matters set forth below.

All terms herein and in the Agreement and not defined herein shall have the
same meanings as in the Agreement.

                AIRCRAFT SCHEDULE RELIABILITY GUARANTEE

Subject to the terms and conditions set forth in this Guarantee BRAD hereby
guarantees that the Achieved Aircraft Schedule Reliability for the Covered
Aircraft during any Reporting Period shall be [CONFIDENTIAL PORTION DELETED].
   93
(A)      SCOPE

         (1) COVERED AIRCRAFT

             The Aircraft Schedule Reliability Guarantee (hereinafter
             referred to as the "Guarantee") shall cover and be in effect
             for the Aircraft delivered to Buyer under this Agreement while
             operated on Buyer's routes during the Guarantee Term
             (hereinafter referred to as "Covered Aircraft").

         (2) GUARANTEE TERM

             The term of the Guarantee is [Confidential Portion Deleted]
             commencing on the first day of the month next succeeding the
             month in which Buyer's first Aircraft enters into revenue
             service (hereinafter referred to as "Guarantee Term").

             Unless earlier terminated or suspended as provided herein, all
             provisions of this Guarantee and BRAD's obligation hereunder,
             shall terminate on the last day of the Guarantee Term.

(B)      DEFINITIONS

         (1) "Aircraft Schedule Reliability Target" shall mean the target
             for the Covered Aircraft set forth in attachment A hereto.

         (2) Each "Reporting Period" during the Guarantee Term shall be the
             longer of (a) six (6) consecutive months or (b) the number of
             full months required for all Covered Aircraft to accumulate a
             minimum of 1,500 scheduled revenue departures.  The initial
             Reporting Period shall commence on the first day of the
             Guarantee Term.

         (3) A "Chargeable Aircraft Schedule Interruption" shall be defined
             as an interruption, that results directly from Verified
             Malfunction(s) of any Aircraft components, equipment or parts,
             excluding Engines and Engine related components specified by
             the Engine manufacturer, installed on the Covered Aircraft
             upon its delivery to Buyer, which results in a cancellation,
             turn back, diverted landing or departure delayed longer than
             fifteen (15) minutes.

         (4) "Verified Malfunction(s)" shall mean failures, or malfunctions
             of any component mentioned above during a Reporting Period and
             where such failures or malfunctions are the primary cause of
             an interruption and are subsequently confirmed by inspection
             or shop test, if applicable, in accordance with Buyer's FAA
             approved maintenance programs.

             [CONFIDENTIAL PORTION DELETED]


                                     -2-
   94
         (5) "Scheduled Revenue Departure" with respect to a Covered
             Aircraft, shall be any scheduled departure of such Covered
             Aircraft for a scheduled revenue flight segment, and any
             one-segment canceled revenue flights.

         (6) The "Achieved Aircraft Schedule Reliability" for a Covered
             Aircraft shall be calculated and expressed as a percentage by
             use of the following formula:

             Any rounding, as required under this Guarantee, in order to
             compare the Achieved Aircraft Schedule Reliability with the
             Aircraft Schedule Reliability Targets, shall be accomplished
             as follows:  if the first digit of the portion to be dropped
             from the number to be rounded is five or greater, the
             preceding digit shall be raised to the next higher number.

         (7) A "Deficiency" occurs when the Achieved Schedule Reliability
             during any Reporting Period is less than the Aircraft
             Scheduled Reliability Target for such Reporting Period, all as
             may be adjusted pursuant to the terms of this Guarantee.

(C)      REMEDIAL ACTION

         (1) If, for any Reporting Period during the Guarantee Term, Buyer
             notifies BRAD that the Achieved Aircraft Schedule Reliability
             is below the applicable Aircraft Schedule Reliability Target
             and the contents of the applicable reports mentioned in
             Section (D)(1) confirm the contents of Buyer's notification,
             then BRAD shall:

              (i) investigate circumstances and the possible causes for
                  excessive interruptions, and

              (ii)        [CONFIDENTIAL PORTION DELETED].

         (2) If, at the end of the next Reporting Period after which the
             foregoing recommended remedial actions have been accomplished
             it is Buyer's and BRAD's opinion based on Buyer's notification
             that the Achieved Aircraft Schedule Reliability is
             [CONFIDENTIAL PORTION DELETED], then BRAD shall:

             [CONFIDENTIAL PORTION DELETED].

(D)      ADMINISTRATIVE REQUIREMENTS

         (1) Buyer shall submit to BRAD within thirty (30) days after the
             Reporting Period, the total number of Chargeable Aircraft
             Schedule Interruptions and the total number of Scheduled
             Revenue Departures during the preceding six (6) months.
             Notwithstanding what is stipulated above, during any Reporting
             Period when any Guarantee remedies are being provided by BRAD
             to Buyer, Buyer shall submit to BRAD monthly reports of
             Chargeable Aircraft Schedule Interruptions.


                                     -3-
   95
             Each report shall also include the average Achieved Aircraft
             Schedule Reliability for all of the previous Reporting Period
             for the relevant year of the Guarantee Term, if any.

         (2) Upon request, Buyer shall submit to BRAD reasonable proof that
             any interruption claimed by Buyer to constitute a Chargeable
             Aircraft Schedule Interruption does in fact constitute a
             Chargeable Aircraft Schedule Interruption.  Buyer shall
             maintain and submit to BRAD such records, data and reports as
             may reasonable be required to (i) determine Achieved Aircraft
             Schedule Reliability, (ii) analyze the problems encountered
             and the causes thereof, and (iii) when required, develop
             appropriate remedial action.

         (3) BRAD may require Buyer to furnish, from time to time, such
             additional information as is reasonably necessary to monitor
             Chargeable Aircraft Schedule Interruptions or investigate any
             related schedule reliability problem.

         (4) Buyer shall maintain complete records referred to above in
             support of all reports required from Buyer under this
             Guarantee and such records shall be retained by Buyer for a
             minimum of one year after submittal of the report to which
             they pertain.  All such records and any other data in Buyer's
             possession reasonably required for the proper administration
             of this Guarantee shall, upon request, be made available at
             Buyer's facilities for examination by BRAD.

         (5) [CONFIDENTIAL PORTION DELETED].

         (6) All reports under this Guarantee shall be submitted by Buyer
             to the attention of:

(E)      COMPLIANCE AND VALIDITY

         If at any time Buyer is deficient in forwarding the Achieved Aircraft
         Schedule Reliability as defined in Section (D) in this Guarantee on
         the due dated during or after [CONFIDENTIAL PORTION DELETED].


(F)      GENERAL CONDITIONS AND LIMITATIONS

         (1) The Aircraft Schedule Reliability Targets defined in Section
             (B)(1) herein and set forth in Attachment A hereto are based on
             certain factors controlled by Buyer revenue service operations
             such as annual utilization, average stage length, average
             turnaround time, average thru-stop time and certain other
             maintenance and operational factors under Buyer's control.
             These factors are identified in Attachment A hereto. If, for
             any Reporting Period, the Covered Aircraft experience changes
             in any such factors, the Aircraft Schedule Reliability Target
             for such Reporting Period shall be adjusted:

                                     -4-

   96

              (i) to reflect changes in the schedule reliability parameters 
                  set forth in Attachments A, if any such parameter increases 
                  or decreases by more than [CONFIDENTIAL PORTION DELETED].  
                  Then the Aircraft Schedule Reliability Target will be 
                  reviewed by both parties. The intent of such review shall be 
                  for the parties to agree upon a reasonable adjustment to the
                  targets to compensate for the change in operations;

             (ii) to reflect changes that cause "Other Flight Profile Factors" 
                  to exceed the limits set forth in Attachment A, by mutual 
                  agreement between BRAD and Buyer.

         (2) If BRAD or any Vendor issue no-charge service bulletins or
             service bulletins with no-charge retrofit kits which, when
             incorporated, will improve Aircraft Schedule Reliability, Buyer
             shall implement such at the earliest reasonable time, but in no
             event later than [CONFIDENTIAL PORTION DELETED] by mutual
             agreement between BRAD and Buyer to be consistent with Buyer's
             FAA approved maintenance program, such period commencing with
             the date of Buyer's receipt of such service bulletins or
             sufficient retrofit kits to support Buyer's reasonable
             installation schedule for such kits. [CONFIDENTIAL PORTION
             DELETED].

         (3) BRAD shall have the right (after consultation with Buyer) to
             inspect and review Buyer's maintenance facilities, programs and
             procedures as they relate to this Guarantee.  If BRAD
             recommends in writing reasonable changes in Buyer's maintenance
             programs and procedures which are economically feasible and
             would, based on data submitted by BRAD to Buyer, improve the
             Achieved Aircraft Schedule Reliability, and Buyer does not
             effect such changes or delays effecting such changes beyond the
             period specified in Section (F)(2) above for effecting service
             bulletins, BRAD and Buyer shall negotiate an equitable
             adjustment to the occurrences which will thereafter constitute
             a Chargeable Aircraft Schedule Interruption.

         (4) [CONFIDENTIAL PORTION DELETED].

         (5) [CONFIDENTIAL PORTION DELETED].

         [CONFIDENTIAL PORTION DELETED].

         [CONFIDENTIAL PORTION DELETED].

1.4      INTERFACE PROBLEM

         1.4.1    INTERFACE PROBLEM RESOLUTION

         If Buyer experiences any technical problem in the operation of
         the Aircraft or its systems which, after reasonable
         investigation,  is not readily identifiable by Buyer, but which
         Buyer reasonably believes to be attributable to the design
         characteristics of one or more components or systems of the Aircraft
         (an "Interface Problem"), BRAD shall, if requested by Buyer and
         without additional charge to Buyer, promptly conduct an analysis of
         such Interface Problem to determine, its cause or causes and to
         recommend corrective action.  If BRAD determines that the Interface
         Problem is attributable to the design of BRAD parts, BRAD shall, if
         requested by Buyer, correct the design to the extent of existing
         obligations of BRAD under Exhibit F, Aircraft Warranty.

         If BRAD determines that the Interface Problem is attributable to the
         design of a Vendor Part, BRAD shall, if requested by Buyer, reasonably
         assist Buyer in processing any warranty claims Buyer may have
         against the Vendor of the part.  BRAD shall also take reasonable
         action with the Vendor to obtain a correction of the Interface
         Problem.

         If BRAD determines that the Interface Problem is attributable
         jointly to the design of BRAD parts and Vendor parts, BRAD shall, if
         requested by Buyer reasonably seek a cooperative solution with the
         Vendor(s).

         1.4.2    VENDOR INTERFACE PROBLEM BACKSTOP

         For those Interface Problems which are determined to be attributable
         to the design of a Vendor Part, excluding Powerplant Parts, if the
         parties agree that a vendor is in default regarding the resolution of
         an Interface Problem during the applicable warranty obtained by BRAD
         from such vendor, BRAD shall take reasonable action to correct the
         Interface Problem.

1.5      VENDOR PRODUCT SUPPORT AGREEMENTS

         BRAD has made and will continue to make reasonable efforts to establish
         and maintain favorable agreements with Vendors with respect to their
         providing product support goods and services.  The vendor product
         support agreements describe the goods and services, and provide the
         terms and conditions to which Vendors must adhere. Generally these
         agreements cover but are not limited to Spare Parts availability and


                                      -3-

         technical assistance, training, technical data and manuals, repair and
         overhaul, and warranty.

         In the event the parties agree that a vendor is in default of a
         material obligation under any applicable product support agreement
         obtained by BRAD from that vendor, BRAD shall take reasonable action to
         meet the terms and conditions of that agreement except for vendor
         warranty, the terms and conditions of EXHIBIT F, Article 2.2 shall
         apply.

1.6      ADDITIONAL SERVICES

The obligation herein contained by Mesa and its personnel shall continue in
full force and effect whether or not any other agreement to perform work or
