      The rights granted to Licensee hereunder shall be exercised by Licensee
world wide.

      6. DEFINITION OF "NET SALES PRICE":

      For the License herein granted with respect to the Licensed Patents,
Licensee shall pay to Licensor royalties in the sum equal to five percent (5%)
of the "Net Sales Price" for Licensed Products sold.

      Should Licensor not be paid royalties of at least $25,000.00 for a full
license year, beginning the first license year of this agreement, Licensor shall
have the right: at any time during the succeeding license year to declare this
exclusive license to be a non-exclusive license or to terminate the license, at

the sum of $25,000.00 and such royalties. Such payments must be made within
thirty (30) days of the end of the license year. Licensor must notify Licensee,
in writing, within ninety (90) days of the end of such license year of any

books and records of business transactions by Licensee in connection with the
Licensed Products covered by the Licensed Patents, including, but not limited
to, books and records relating to the "Net Sales Price" and orders for such
products. Licensee's accounting records of sales, shipments, installations and
returns of Licensed Products shall be maintained separately from accounting
records relating to other items manufactured or sold by Licensee. Such books and
records shall be maintained in accordance with generally accepted accounting
procedures. Licensor, or its duly authorized agents or representatives, shall
have the right to inspect such books and records at Licensee's premise during
regular business hours, provided that Licensor shall give Licensee at least ten
(10) days advanced written notice of its intention to do so and provided that

kept with respect to the Licensed Products. Should any audit disclose that the
royalties paid exceed the actual royalties due, Licensee shall be entitled to a
credit equal to such excess royalties against the royalties next accruing under
this Agreement. In the event no further royalties will be accruing under this
Agreement, then to the extent such audit discloses that the royalties paid
exceeded the actual royalties due, the excess shall be paid to Licensee.

      9. LICENSEE'S MONTHLY REPORTS 0F SALES AND ROYALTY PAYMENTS:

      On or before the first day of each month during the term hereof, Licensee
shall deliver to Licensor written statements certified to be true and correct by

      Licensee shall use its best efforts and skills to make, use and sell the
Licensed Products. In the event Licensee fails to sell Licensed Products using
such best efforts and skills, Licensor shall have the right to cancel and
terminate this Agreement by giving written notice of such termination to
Licensee.

      11. RESTRICTIONS UPON SUBCONTRACTS:

imports for the manufacture, use and sale of Licensed Products upon written
consent of Licensor. Any subcontracts by Licensee shall be governed and
condition on the same rights, privileges, restrictions and requirements
including payment of royalties, right to inspect, and to take accountings as
provided elsewhere in this Agreement.

      12. ASSIGNMENT AND TRANSFERS:

      13. PRESERVATION OF THE PATENTS:

      Licensee shall cause to appear on all Licensed Products and/or on all
materials used in connection with the sale thereof such legends, markings and
notices as may be required by laws governing the geographic area in order to
give appropriate notice of all patent rights granted and pertaining to the
Licensed Patents. Such products or materials associated with the Licensed
Product should bear the mark "Patented" and the Patent Number(s) of the Licensed
Patent(s).

      14. INFRINGEMENT AND OTHER LITIGATION:

      Licensor represents that it is the sole owner of all rights to the
Licensed Patents exclusive of the rights of all others. The Licensor has no
present knowledge or belief that any of the claims of the Licensed Patents are
not valid and enforceable and that Licensor has the absolute right to grant this
License.

      In order to protect rights of each party under this Agreement, each party
will keep the other fully informed of the infringement of any Licensed Patent
by third parties. The Licensor shall have the right to be represented by council
at Licensor's expense in any legal action taken to enforce any patent rights
with respect to the Licensed Patents against a third party infringer.
Responsibility for the cost and expenses of such legal action shall be mutually
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.

      With respect to any third party suit or action against Licensee whether by
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,


                                        5

exclusive of royalties otherwise due to the Licensor.

Licensee shall default in the performance of any of the terms and conditions to
be performed hereunder, including the payment of royalties, and the same shall
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

      Licensee does indemnify and hold harmless Licensor for any liability or
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.

      18. ATTORNEY'S FEES AND APPLICABLE LAW:

      In the event Licensor or Licensee shall commence any action or proceeding
against the other by reason of any breach or claimed breach of the performance
of any of the terms or conditions of this Agreement, or to seek a judicial
declaration or rights hereunder, the prevailing party of such action or
proceeding shall be entitled to reasonable attorney's fees to be fixed by the
court or the applicable hearing officer(s). In any legal action or proceeding
brought in which any right or obligation arising from this Agreement is at
issue, the law applicable hereunder shall be the law of the State of Kentucky.
