Article 11 - TRADEMARK LICENSE FOR OPERATIONS TO BE CONDUCTED
             BY CONTRACTOR PURSUANT TO THIS AGREEMENT

          Section 11.01 GRANT OF TRADEMARK LICENSE

          Contractor will conduct all operations described in Section 2.01
above, and any additional operations undertaken by subsequent amendment hereto
under the trademark "USAir Express" and shall utilize the USAir Trademarks
consisting of the exterior color decor and patterns on its aircraft as
prescribed by USAir. USAir hereby grants to Contractor a nonexclusive,
nontransferable license to use such USAir Trademarks in connection with the
services to be rendered by Contractor under this Agreement; PROVIDED, HOWEVER,
that at any time during the life of this Agreement, USAir may alter, amend or
revoke the license hereby granted and require Contractor's use of any new or
different USAir Trademarks in conjunction with the air transportation services
provided hereunder as USAir may determine in the exercise of its sole discretion
and judgment.

          Section 11.02 TERMS AND CONDITIONS GOVERNING TRADEMARK LICENSE

          (a) Contractor hereby acknowledges USAir's ownership of the USAir
Trademarks, further acknowledges the validity of the USAir Trademarks, and
agrees that it will not do anything in any way to infringe or abridge USAir's
rights in its trademarks or directly or indirectly to challenge the validity of
the USAir Trademarks.

          (b) Contractor agrees that, in providing the services to be provided
under this Agreement in conjunction with one or more of the USAir Trademarks, it
will conform to such standards of service (including types of aircraft,
qualification of personnel, customer

                                      11.1
<Page>

service standards, and other reasonable quality control measures) as may be
prescribed by USAir either specifically in this Agreement or by subsequent
written communications to Contractor. USAir shall have the right, through such
agents or representatives as it may designate, to inspect the services and
standards being performed by Contractor under this Agreement, and in the event
that, in USAir's opinion, there has been some deviation from such services
and/or standards, Contractor agrees upon written notice from USAir to rectify
promptly any such deviation.

          (c) Contractor shall not, without USAir's express prior written
consent, advertise the services to be rendered hereunder, nor make use of the
USAir Trademarks referred to in Section 11.01 above in any advertising. USAir
shall have absolute discretion to withhold its consent concerning any and all
such advertising and use of the USAir Trademarks in advertising by Contractor.
In the event USAir approves the use of such USAir Trademarks in any advertising,
such advertising shall identify USAir as the owner of such trademark(s), and to
the extent that any mark is registered, shall so specify.

          (d) To the extent that Contractor is licensed to use the mark
"USAir," Contractor will use said mark only in the mark "USAir Express" and then
only in conjunction with the services specifically embraced by this Agreement.

          (e) Nothing in this Agreement shall be construed to give Contractor
the exclusive right to use the USAir trademarks, or to bridge USAir's right to
use and/or to license its trademarks, and USAir hereby reserves the right to
continue use of the USAir

                                      11.2
<Page>

Trademarks and to license such other uses of said trademarks as USAir may
desire.

          (f) No term or provision of this Agreement shall be construed to
preclude the use of the trademarks "USAir Express" or the aircraft exterior
color decor and patterns by other individuals or corporations not covered by
this Agreement, except in the markets covered by Section 2.01 (a) of this
Agreement.

          (g) Should this Agreement be cancelled or otherwise terminated for
any reason as set forth in Article 9 hereof, the USAir Trademarks shall revert
to USAir and shall not thereafter be used by Contractor in connection with any
operations of Contractor.
