seventy five hundred U.S. dollars (U.S. $7,500.00) as reimbursement for
Licensors existing patent costs for said Patent Rights. This payment will be

V  REPORTS AND ROYALTIES

(a)     Commencing in the calendar year 2004, Licensee agrees to make written
reports to Licensor biannually, within sixty (60) days after the first day of
each January and July during the life of this Agreement, and, as of such dates,
stating in each such report the total Net Sales Proceeds during the preceding

Proceeds from the effective date of this Agreement to the date of said report.
Such bi-annual reports shall provide the particulars of the business conducted

Agreement as are pertinent to a royalty accounting. These shall include at
least the following:



| | 1. |  | all Licensed Products manufactured, used, sold or otherwise

| | -- |  | -------------------------------------------------------------------------
|
| | 2. |  | total billings for Licensed Products sold, used or otherwise
disposed of;
|
| | 3. |  | deductions applicable, if any; and                                       
|
| | 4. |  | total royalties due.                                                     

(b)     Concurrently with the making of each such report required by
paragraph (a) of this Article
V, Licensee will pay to Licensor royalties at the rate of 3% percent of Net

(c)     Beginning in the calendar year 2004 Licensee agrees to pay
annual minimum royalties
(Minimum Royalties) as follows:

until the termination or expiration of
this Agreement: fifteen thousand United States Dollars (U.S. $15,000).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------

In the event that the Running Royalties paid under paragraph (b) of this
Article (V) with respect to a calendar year exceed the applicable Minimum
Royalty for that year, it is understood that no separate Minimum Royalty is to
be paid for that year. In the event that the actual Running Royalties paid
with respect to a calendar year are less than the applicable Minimum Royalty
for that year, Licensee shall be obligated to pay within sixty (60) days after
the end of each such year the difference between the actual royalties it paid
with respect to said year and the Minimum Royalty for that year to satisfy this
Minimum Royalty payment provision.

(d)     Licensee agrees to make a written report to Licensor within sixty (60)
days after the date of any termination of this Agreement, which shall identify
all Net Sales Proceeds and sublicensing share realized prior to termination of

to Licensor all royalties due on the basis of this report at the rates defined
in paragraphs (b) and (c) of this Article and all sublicensing income due.

(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.
Licensee 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 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 nor 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 becomes 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

(a)     Licensor makes no representation or warranty, either expressed or
implied, and no

Page 5 of 12



---



##### 



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;

(2)     a warranty or representation that any product made, used, sold
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, judgements 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
insured and evidencing that Licensee maintains insurance, in an amount of at
least one million dollars ($1,000,000.00), for all liabilities, obligations or
claims arising out of the manufacture, use, sale or disposition of Licensed
Products and the indemnification, hold harmless and other obligations
undertaken by Licensee under this Agreement. Licensee agrees that it will provide such certification of insurance at no
expense to 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.
The specified minimum amount of insurance coverage shall not be construed to
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

Licensor, any and all expenses, judgments or sanctions incurred in connection
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,
except for monies due to Licensor under this License Agreement.

(d)     Licensor and Licensee hereby agree to cooperate with each other in the
prosecution of any legal infringement action or settlement discussions and each

helpful in the prosecution of such action of which it may have knowledge or
which may be readily available to it without incurring substantial expense.

(e)     Should Licensee commence a suit under the provisions of this Article
and thereafter elect to abandon this suit, it shall give timely notice to the
Licensor who may, if it so desires, continue prosecution of such suit, 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.

royalties, shall run in favor of the successors, assigns
or other legal representatives of Licensor.

(b)     Licensees rights under this Agreement and the license herein granted
shall not be assigned for the benefit of creditors of Licensee or otherwise,
nor shall such rights or license pass to any receiver of Licensees assets,
except for a person or corporation succeeding to the entire business and good
will of Licensee in the manufacture and sale of Licensed Products as the result
of a sale, consolidation, reorganization or otherwise, provided such person or
corporation shall, without delay, accept in writing the provisions of this
Agreement and agree to become in all respects bound thereby in the place and
stead of Licensee. Licensees rights under this Agreement and the license
herein granted shall not be otherwise transferred without the written consent

to Licensor that it will comply with all of the requirements of the U.S. Export
Control Regulations.

(b)     Violation of the U.S. Export Control laws or regulations by Licensee
shall constitute grounds for Licensor, in its sole discretion, to terminate
this license agreement. Failure to obtain any needed export control license
may result in criminal liability under the United States law.

XII  TERM AND TERMINATION

breach of any covenant herein contained, and shall fail

Page 8 of 12

hereunder at any time by written notice given to the Licensor at least six (6)
months prior to the date when such termination is to become effective.

Licensee from its obligations under Article V hereof to make a terminal report
and maintain records, or from its liability for payment of royalties on
Licensed Products sold or otherwise disposed of hereunder prior to the date of
such termination or expiration, or for payment of annual minimum royalties due,
and shall not prejudice the right of Licensor to recover any royalty or other
sums or consideration due or accrued at the time of such termination or
expiration and shall not prejudice any cause of action or claim of Licensor
accrued on account of any breach or default by Licensee.

(e)     Any termination or expiration of this Agreement shall not prejudice
the right of Licensor to conduct a final audit of the records of Licensee in
accordance with the provisions of Article VII hereof.
