not valid and enforceable and that Licensor has the absolute right to grant this

agreed upon in writing between the Licensor and Licensee prior to the
institution of any such legal action. In any action by Licensor or Licensee
whether by original petition, complaint, or by counterclaim against a third
party for violation of patent rights in the Licensed Patents, each party shall
be entitled to retain any settlement, recovery, and/or awarded damages in
proportion to the agreed upon percentage of the cost and expenses of such
action. Absent any agreement for maintaining such a legal matter to enforce the
Patent Rights, Licensor shall, in its own judgment, take whatever action it
deems necessary at its own expense.

original petition, complaint, or by counter-claim, seeking to declare invalid
and/or unenforceable all or any of the claims of any of the Licensed Patents,
the defense fees, cost, and expenses shall be agreed upon by the parties hereto
as soon as reasonably practical after the commencement or such third party suit
or action. If Licensor refuses to participate in any such third party suit or
action, the Licensee may defend and prosecute such action and, in such event,
shall be entitled to the entire amount of any award of damages, settlement or
recover,

not be cured within ten days (10) after written notice to Licensee, Licensor
may, at its option, or any time thereafter, cancel and terminate this Agreement.

      16. LICENSOR'S RIGHT UPON TERMINATION:

      In the event this Agreement is cancelled or terminated, Licensee shall
assign and transfer any and all rights of Licensee to all Licensed Patents and
Licensed Products to Licensor and shall not thereafter use the same in any
manner. Upon cancellation or termination, all Licensee's stock of Licensed
Products on hand may be purchased by Licensor.

      17. INSURANCE

claim thereof based upon the manufacture, use and sale by Licensee of the
Licensed products. To this end, Licensee and its Sub-Licensees, if any, agree to
carry product liability insurance with respect to License Products. Such
insurance may be obtained in conjunction with product liability insurance which
covers products other than the Licensed Products. Licensee shall deliver to
Licensor, at Licensor's request, a certificate evidencing the existence of such
insurance policies promptly upon written request by Licensor.
