Covenant Not To Assert

International Characters, Inc., on its own behalf and on behalf of
its successors in interest, irrevocably covenants that, subject
solely to the Reciprocity Requirement below, it will not assert or
enforce any rights in any claims in its Canadian, U.S., or foreign
patents, including the right to assert contributory infringement,
inducing infringement, or willful infringement, against anyone
because of the following activities ("Permitted Activities"):

   1. the use of Open Source Software (in combination with hardware); or
   2. the making, sale, offer for sale, importation, licensing or
distribution of Open Source Software; or
   3. the making or use of software or hardware for Experimentation,
Research or Teaching.

In order to be clear that this covenant expressly excludes certain
commercial activities, this covenant does not apply to the making, use,
sale, offer for sale, importation, licensing or distribution of any
software, hardware, or combination of software and hardware, other than
as specified above.

In this covenant, the following definitions of terms apply:

    * "Open Source Software" means software actually distributed to the
public under software licenses that have been expressly approved by Open
Source Initiative or the Free Software Foundation as of the date of this 
covenant, and that provide that every licensee is free to make copies of 
the software or derivative works thereof, to distribute them without
payment of royalties or other consideration, and to access and use the
complete source code of the software
    * "Experimentation" means activities relating to the evaluation or
testing of infringing hardware or software, including use by others for
limited trials, prior to continuing use, sale, licensing, or other
distribution of that software or hardware in commerce or for commercial
purposes.
    * "Research" means activities to advance and disseminate knowledge
about infringing software or hardware and improvements thereto through
publications, patent applications and Open Source Software, but not
including the use, sale, licensing, or other distribution of those
advancements in commerce or for commercial purposes.
    * "Teaching" means activities relating to explaining to students how
to make, use, or improve infringing software or hardware.

Reciprocity Requirement: Notwithstanding the commitment above, this
International Characters covenant shall not apply and International
Characters makes no assurance, covenant or commitment not to assert or
enforce any or all of its patent rights against any individual,
corporation or other entity that asserts, threatens or seeks at any time
to enforce its own or another party's Canadian, U.S. or foreign patents
or patent rights against any Permitted Activities by anyone.

This covenant is not an assurance either (i) that any of International
Characters issued patents cover any particular software or hardware or
are enforceable, or (ii) that any particular software or hardware would
not infringe patents or other intellectual property rights of any third
party.

No other rights except those expressly stated in this covenant shall be
deemed granted, waived, or received by implication, or estoppel, or
otherwise.
