                                       4

<PAGE>

         (c) Minimum Annual Royalties:

              a.  For the calendar year ending December 31, 2004, Licensee
                  agrees to pay a minimum royalty of ten thousand United States
                  Dollars (U.S. $10,000.00). In the event that the actual
                  royalties for that calendar year exceed $10,000.00, it is
                  understood that no minimum royalties are to be paid for that
                  year. In the event that the actual royalties paid for a
                  calendar year are less than this minimum royalty of
                  $10,000.00, Licensee shall be obligated to pay within sixty
                  (60) days of December 31, 2004, the difference between the
                  actual royalties it paid during said year and the minimum
                  royalty of $10,000.00 to satisfy this minimum royalty
                  provision.

              b.  For the calendar year ending December 31, 2005 and each
                  calendar year thereafter, Licensee agrees to pay a minimum
                  royalty of fifteen thousand United States Dollars (U.S.
                  $15,000.00). In the event that the actual royalties for any
                  calendar year exceed $15,000.00, it is understood that no
                  minimum royalties are to be paid for that year. In the event
                  that the actual royalties paid for a calendar year are less
                  than this minimum royalty of $15,000.00, Licensee shall be
                  obligated to pay within sixty (60) days of each December 31,
                  thereafter, the difference between the actual royalties it
                  paid during said year and the minimum royalty of $15,000.00 to
                  satisfy this minimum royalty provision.

         (d) Licensee agrees to make a written report to Licensor within sixty
(60) days after the date of any termination of this Agreement, stating in such
report the total Net Sales Proceeds


                                       5

<PAGE>

up to such date of termination which were not previously reported to Licensor.
Concurrently with the making of this report, Licensee will pay to Licensor all
royalties due on the basis of this report at the rate defined in paragraphs (b)
and (c) of this Article.

         (e) All monies payable hereunder shall be paid in United States
Dollars.

VI - SUBLICENSES
----------------

         (a) The grant under Article II above includes the right to grant
sublicenses. Any sublicense granted by Licensee shall be subject to the terms
and conditions of this Agreement, including the insurance requirement in Article
VIII hereof, and shall contain an express provision to that effect. No
sublicense shall relieve Licensee of any of its obligations under this
Agreement. Licensee agrees to forward to Licensor a fully executed copy of each
sublicense agreement it enters into within thirty (30) days after execution
thereof.

         (b) Licensee agrees to include in its reports required in Article V
above an accounting of all consideration received by Licensee from its
sublicensees. Licensees agrees to pay Licensor, in addition to all of the
amounts provided for in Article V above, fifty percent (50%) of all
consideration of any nature, including, for example, license fees, earned
royalties, and minimum royalties, received by Licensee from its sublicensees.

         (c) Upon the termination of this Agreement for any cause, any and all
existing sublicenses hereunder shall thereupon automatically terminate. This
shall be made a condition of any sublicense that may be granted by Licensee.

VII - AUDITING

(a) Licensee agrees to keep for a period of three years the records used to
prepare the reports required by Article V hereof. Such records shall be in
sufficient detail to enable the

<PAGE>

royalties and licensing fees payable hereunder by Licensee to be clearly and
fully determined. Licensee further agrees to permit such records to be examined
from time to time to the extent necessary to verify the reports provided for in
Article VI hereof, such examination to be made at the expense of Licensor by an
auditor appointed by Licensor, or at the option and expense of Licensee, by an
independent Certified Public Accountant who shall be appointed by Licensee and
who shall be acceptable to Licensor.

         (b) Licensor agrees to use its best efforts to maintain in confidence
the information reported to it in Licensee's biannual sales reports and any
confidential information it obtains through its audit rights. Licensor will use
its best efforts to neither disclose this information outside of its
organization or use this information for any purpose other than collection of
royalties from Licensee under this Agreement.

         (c) Licensee agrees that the confidentiality and use provisions of this
Article shall not apply to the following:

         (1) any information which appears in printed publications or which
otherwise is or become generally known in the trade other than through the fault
of Licensor;

         (2) any information which Licensor can show by written records was in
its possession prior to the disclosure hereunder; or

         (3) any information which comes into the possession of Licensor without
covenants of secrecy from another party who is under no obligation to Licensee
to maintain the confidentiality of the information.

VIII - DISCLAIMER, INDEMNIFICATION, HOLD HARMLESS AND INSURANCE

<PAGE>

representation or warranty shall be implied, with respect to the License herein
granted other than that Licensor has the right to grant said license.

         (b) Nothing in this Agreement shall be construed as:

             (1) a warranty or representation by Licensor as to the validity or
         scope of any Patent Rights;

         or otherwise disposed of or any method practiced under any license
         granted under this Agreement is or will be free from infringement or
         claims of infringement of patents, copyrights or any other property
         right of third parties; or

             (3) granting by implication, estoppel or otherwise any licenses or
         rights under patents or other property rights of Licensor other than
         said Patent Rights, regardless of whether such patents are dominant or
         subordinate to any Patent Rights.

         (c) Licensor shall not be liable for any injury, losses or damages,
including special or consequential damages or losses incurred by Licensee, nor
for claims for such damages, losses or other injuries asserted or levied against
Licensee, arising out of Licensee's practice of the Grant set forth in Article
II of this Agreement. Licensee shall indemnify and hold harmless Licensor and
the U.S. government from any claims, actions, judgments or awards arising out
of Licensee's practice of the Grant set forth in Article II, or out of
Licensee's manufacture, use, sale or disposition of Licensed Products.

         (d) Licensee shall, at the time of signing of this Agreement, deliver
to Licensor a certificate of liability insurance showing Licensor as a named

Licensor. Licensee further agrees to periodically provide evidence of its
continuing to maintain substantively and fiscally equivalent liability
insurance for the term of this Agreement and for twenty (20) years thereafter.

create a limitation on the obligation of Licensee.

IX - INFRINGEMENT OF LICENSOR'S PATENT RIGHTS BY THIRD PARTIES

         (a) Should Licensor or Licensee become aware of any infringement or
alleged infringement in the United States, its territories and possessions, of

writing of the name and address of the alleged infringer and of the alleged acts
of infringement, and provide any available evidence of the alleged acts of
infringement.

with such legal action shall be borne solely by Licensee, who shall retain for
itself, any and all monies or other benefits derived from such legal action,

provided however that the sharing of expenses and any recovery in such continued
suit shall be as agreed upon between Licensor and Licensee.

         (f) If, at any time during this Agreement, Licensor or Licensee shall
be unable to uphold the validity of any of the Patent Rights against any alleged
infringer, Licensee shall not have or assert any damage claim or a claim for
refund or reimbursement against Licensor.
