                           LM3000 SOFTWARE AGREEMENT

         This LM3000 Agreement (this "Agreement") is made as of March 30, 1998,
by and between Aironet Wireless Communications, Inc., a Delaware corporation
("Aironet"), and Telxon Corporation, a Delaware corporation ("Telxon").

                                   BACKGROUND

         WHEREAS, Telxon is the majority stockholder of Aironet;

         WHEREAS, Telxon heretofore sold Aironet's LM3000 products to its
customers, and thereafter authored software upgrades for the LM3000 products to
make such products compatible with the IEEE 802.11 standard for wireless
computer networks (the "Upgrade"); and

         WHEREAS, Aironet desires to receive from Telxon the right to utilize
the Upgrade.

                                   AGREEMENT

         NOW, THEREFORE, in consideration of the foregoing premises and the

disassemble, merge and link the source code of the Upgrade, and to load,
support, service, maintain, repair, reconstruct, reconfigure and upgrade,
integrate, install, use, market, sell, offer for sale, lease and transfer copies
of the object code of the Upgrade. Aironet shall take the same steps to bind
transferees of copies of the Upgrade to a commercially reasonable software
license agreement, that Aironet takes with respect to its own software.

         2. CONTRACTORS. Aironet may exercise the rights granted to it in
Section 1 either through its employees or through its contractors.

         3. IMPLIED LICENSE. Subject to the restrictions imposed under the

have an implied license to use and transfer copies of the object code of the
Upgrade, in the form delivered by Aironet to its immediate customer.

         4. DELIVERY. Upon Aironet's execution of this Agreement, to the extent
that a copy is not already in Aironet's possession, Telxon shall deliver to
Aironet a copy of the source and object code of the Upgrade.

         5. DISCLAIMER OF WARRANTY AND LIABILITY. TELXON IS PROVIDING THE
UPGRADE TO AIRONET "AS IS." TELXON MAKES NO REPRESENTATION OR WARRANTY OF ANY
KIND WITH RESPECT TO THE UPGRADE, WHETHER EXPRESS OR IMPLIED OR ARISING UNDER
ANY

OTHERWISE, WHETHER OR NOT TELXON IS MADE AWARE OF THE POSSIBILITY OF SUCH
DAMAGES.

         6. GOVERNING LAW; JURISDICTION. This Agreement shall be construed under

contemporaneous understandings and agreements, written or oral, between the
parties relating to the subject matter hereof.

         8. ASSIGNABILITY. Neither this Agreement nor any right or obligation

of no effect. The merger, consolidation, asset sale, change of control, or any
other reorganization of Aironet with or into a Competitor, or of a Competitor

Subject to the foregoing, this Agreement shall be binding upon and enforceable
by, and shall inure to the benefit of, the parties hereto and their respective
successors and assigns. Nothing in this Agreement is intended to give any person
not named herein the benefit of any legal or equitable right, remedy or claim
