         This Sixth Addendum to Lease (hereinafter referred to as the
"Addendum")is made and entered into as of this day of March, 1998, by and
between JOHN D. DELLAGNESE III, hereinafter referred to as "Lessor", and TELXON
CORPORATION, hereinafter referred to as "Lessee". Reference is made to that
certain "Standard Office Lease (Modified Net Lease)" dated July 19, 1995, which,
together with the Attachments, Exhibits, and Addendum of such lease, together
with four additional Addendum to Lease documents, are collectively referred to
as the "Lease". In the event of a conflict between the terms of the Lease and
the terms of this Addendum, the terms of this Addendum shall control.

hereinafter set forth, it is agreed to by and between the parties as follows:

         1. On or before April 1, 1998, Lessee will completely vacate all of the
space which it is presently leasing on the second floor of the Building and
surrender such space to Lessor, and space will no longer be a part of the
premises described in the Lease.

         2. In consideration of the foregoing, on or before April 1, 1998,
Lessee shall pay to Lessor a one time cancellation fee of $28,461.13.

         3. As a result of the above, as of April 1, 1998, and thereafter,
Lessee's premises in the Building will consist of approximately 44,827 rentable
square feet; the annual base rent for such premises shall be $748,526.26 per
year, payable in equal monthly installments of $62,377.19 per month, on the
first day of each month, in advance; and Lessee's Share, per Section 4(e) of the
Lease for said premises shall be 48.24%. The state of affairs described herein
shall begin on April 1, 1998 and shall end at midnight on February 28th, 2001,
