                                                                     DAC 96-29-M

Federal Express Corporation

Memphis, Tennessee  38132


Federal Express Corporation (Federal Express) and McDonnell Douglas Corporation,
a wholly-owned subsidiary of The Boeing Company (MDC), have entered into
Modification Services Agreement Document No. DAC 96-29-M (the "Agreement") dated
September 16, 1996, which Agreement covers Federal Express' desire to
incorporate certain modifications in its DC-10 aircraft (the "Aircraft", as
defined in the Agreement) and MDC desires to perform such modifications. As a
further consideration of the parties hereto, this Letter Agreement No. 9 shall
constitute a part of said Agreement.

     WHEREAS, Boeing and FedEx have jointly concluded that it is in the best
interests of the MD-10 Program to allow FedEx to accept responsibility to
accomplish, either directly or by contracting with a subcontractor, only the
touch labor, administration of such contract and oversight related to the
following tasks (collectively the "Specified Services"):

- -    The work cards listed in Attachments B1 through B5 of Exhibit K to the
     Agreement (the "Heavy Maintenance Check")

- -    The work cards from Exhibit C to the Agreement (Standardization)

- -    The work cards from Exhibit F to the Agreement (Refurbishment)

- -    The Non Routine Services associated with the above

     NOW, THEREFORE, contingent on MDC executing an agreement with Aeronavali in
which MDC is relieved of its obligations to Aeronavali to provide any additional
Heavy Maintenance Check work packages for accomplishment by Aeronavali, and
contingent on Aeronavali and FedEx executing an agreement to accomplish the
Specified Services, and in consideration of the mutual covenants herein, MDC and
Federal Express agree to amend the Agreement to reflect the reduction of work
scope resulting from FedEx accomplishing the Specified Services subject to the
following terms and conditions:

1.   In consideration of FedEx's performance of the Specified Services set forth
     above, the Price to be paid to MDC by FedEx upon Redelivery of the
     twentieth (20th) Aircraft Delivered to MDC (designated as fuselage 42) and
     subsequent (collectively the "Non-Mx Aircraft") shall not include [ *

                                                         ]

     a)   Any of the Services not performed by FedEx or its subcontractor which
          are required by the Specified Services, or any additional workscope
          added to the MJCS in a subsequent revision, shall, at FedEx's request,
          be performed by MDC pursuant to the prices noted in Exhibit K,
          Attachment A or C to the Agreement, or an individually negotiated and
          executed Additional Services Request (ASR) via the ASR process defined
          in the Agreement, as applicable. The fixed labor price for such an ASR
          shall be calculated [ *


                                                                           ]

1-27-99                                                   Letter Agreement No. 9
                                                                     DAC 96-29-M
                                                                          Page 2

          [                                               *


                                                                           ]

     b)   The prices set forth in Exhibit K shall be due and payable by FedEx
          for any given Non-Mx Aircraft only to the extent that the Services
          specified in Exhibit K (i) have been issued on the FedEx MJCS
          applicable to that specific Non-Mx Aircraft (ii) the applicable MJCS
          was submitted to MDC and (iii) the Services specified on the
          applicable MJCS were actually accomplished by MDC on the applicable
          Non-Mx Aircraft.

     c)   The Aircraft shall be deemed completed when the Services required to
          be accomplished by MDC have been substantially accomplished, without
          regard to the level of completion of the Specified Services
          accomplished or yet to be accomplished by FedEx or its subcontractor.
          FedEx and Boeing shall mutually establish a milestone or group of
          milestones and associated progress payment schedule by no later than
          February 12, 1999. The milestone and progress payment schedule shall
          be used to determine when specific Services are complete and the
          associated progress payment is due. The final balance payment shall be
          due and payable upon Redelivery, subsequent to the completion of the
          Services and the Specified Services.

2.   FedEx and MDC shall each be responsible for the costs associated with
     preparation for ferry flight, and the subsequent ferry flight(s) for each
     Non-Mx Aircraft as stipulated below:

     a)   FedEx shall be responsible for [ *



                                                                   ] as noted in
          Exhibit O - Schedule for commencement of the Services by MDC. FedEx
          and MDC acknowledge that in certain instances, the same subcontractor
          will concurrently accomplish the Specified Services on behalf of FedEx
          and the Services on behalf of MDC. (See Paragraph 6. below)

     b)   Notwithstanding Paragraph 2.a) above, for a Non-Mx Aircraft currently
          in storage at Goodyear, AZ, [ *




                                             ]

     c)   For a Non-Mx Aircraft currently in storage at Goodyear, AZ, [ *



                                       ]

3.   At the request of FedEx or its subcontractor, MDC shall provide Parts in
     connection with non-routine tasks accomplished on an Aircraft in accordance
     with the process outlined in "Non-Routine Part Processing", included as
     Attachment A herein. All such Parts

1-27-99                                                   Letter Agreement No. 9
                                                                     DAC 96-29-M
                                                                          Page 3

     provided by MDC will be charged to FedEx in accordance with the Agreement,
     plus a handling charge of [ * ] of such price. The handling charge for each
     Part shall not exceed [ * ].

4.   FedEx hereby irrevocably and unconditionally waives any of MDC's warranties
     which are exclusively related to workmanship for the Specified Services on
     the Non-Mx Aircraft performed by or for FedEx (unless performed by MDC),
     provided, however, nothing in this Paragraph 4. shall extend to or
     otherwise affect warranties which may be applicable to Parts.

5.   Except as expressly set forth in Paragraph 4. above, the performance of the
     Services by FedEx or its subcontractor as contemplated herein shall in no
     manner change, modify, terminate or otherwise affect MDC's warranties
     regarding the Non-Mx Aircraft or in any manner whatsoever modify the terms
     and conditions of the Agreement except as expressly set forth herein.

6.   FedEx and MDC mutually acknowledge that a potential resource conflict
     exists as a result of a subcontractor entering into two separate contracts
     with MDC and FedEx to accomplish work concurrently on one aircraft. FedEx
     and MDC agree to mutually develop a priority of tasks, and mutually resolve
     any resource conflicts that arise to prevent any materially adverse impact
     to the Non-Mx Aircraft Redelivery Date. If a resource conflict arises, then
     the party identifying the conflict shall immediately notify the other
     party. If the resource conflict cannot be resolved within two days of
     notification of the conflict by MDC or FedEx, and such conflict results in
     a delay of MDC's or FedEx's ability to accomplish the services in
     accordance with the scheduled planning in MDC's or FedEx's respective
     contract with the subcontractor, then any resultant delay in the Redelivery
     Date will constitute an Excusable Delay as defined in the Agreement.

7.   All of the terms of the Agreement shall remain in full force and effect,
     except as herein expressly changed, modified or supplemented, or except
     insofar as the terms thereof have been completed, performed or complied
     with prior to the date hereof.

If the foregoing correctly sets forth our understanding, please execute this
Letter Agreement in the space provided below.
