laws of the government of Republica De Panama, having a principal place of
business at c/o Beutler Consulting SA, Chemin G Ritter 3, Ch-1701 Fribourg,

(hereinafter referred to as "INTERNATIONAL").

                                  WITNESSETH

       WHEREAS, MAXON has certain proprietary information, including patented

       WHEREAS, MAXON is desirous of licensing INTERNATIONAL in the field of

INTERNATIONAL in its field of use; and

       WHEREBY, INTERNATIONAL wishes to and is willing to use certain of MAXON's
trademarks on its products, and is willing to meet the quality control standards
of MAXON.

       NOW, THEREFORE, in consideration of the promises and mutual covenants of
the parties hereinafter set forth, it is agreed as follows:

       1.    DEFINITIONS

       (a) FIELD OF USE means any and all practical applications of HTVS as
outlined in Exhibit A hereto and all apparatus utilized in connection therewith.

       (b) TERRITORY means all European countries.

       (c) PATENT RIGHTS means SEILER SWISS' Patent numbers as indicated and
detailed on attached Exhibit C, present technical know-how expected to be
included in any new patent applications of MAXON or SEILER SWISS, and any
additional U.S. and/or foreign patent applications which may be filed by MAXON
or SEILER SWISS during the term of this Agreement in so far as same relate in
any manner to HTVS. PATENT RIGHTS also includes any patent rights that MAXON may
acquire from licensees or otherwise which MAXON is permitted to license to
INTERNATIONAL in the FIELD OF USE during the term of this Agreement.

       2.    LICENSE GRANT

       (a) MAXON hereby grants to INTERNATIONAL an exclusive field-of-use
license to use the PROPRIETARY INFORMATION including the PATENT RIGHTS
throughout the TERRITORY during the term of this Agreement, such use being
expressly limited to the FIELD OF USE.

       3.    CONSIDERATION

       (a) INTERNATIONAL shall pay MAXON $2,500,000 in accordance with the
payment schedule annexed hereto as Exhibit B, as a non-refundable one-time
licensing fee.

       (b) Royalty. INTERNATIONAL shall not be responsible for any royalty
payments to MAXON other than as may be indicated on attached Exhibit D.


                                   - 2 -


       (c) MAXON agrees, at its cost, to conduct research and development at the
request of INTERNATIONAL toward and until production of the first production
prototype plant facility of an operative system utilizing HTVS is completed.

MAXON's cost shall include actual disbursements, direct labor, overhead costs
attributable thereto, and other normal cost items attributable thereto.

       (d) INTERNATIONAL's failure to make payments in accordance with the
Schedule annexed as Exhibits B (and/or D) hereto shall result in loss of
exclusivity, unless INTERNATIONAL pays such license fees and/or royalty payments
(if applicable) within 30 days of receiving written notice from MAXON of such
failure. Once INTERNATIONAL's exclusivity is lost, it shall be lost forever
absent MAXON's written waiver.

       (e) INTERNATIONAL shall keep complete, accurate and up-to-date records of
all production and sales of products or services covered by this License
Agreement with all figures necessary for accurate calculation of any payments
required hereunder, and shall make such records available for inspection during
normal business hours by a representative of MAXON upon reasonable written
notice by MAXON of its intention to conduct such inspection.

       4. TRADEMARKS. INTERNATIONAL shall have the exclusive right to use any
MAXON and/or SEILER SWISS TRADEMARKS with all products or services covered by
this Agreement. It is agreed that any and all of INTERNATIONAL's products and
services covered by this Agreement will meet MAXON's quality standards, which
standards MAXON will make known to INTERNATIONAL. MAXON will have the right to
make any and all reasonable inspections of INTERNATIONAL's facilities, products,
advertising literature, packaging materials, etc. as may be necessary to ensure
that its quality standards are maintained.

       5. SUBLICENSING. INTERNATIONAL shall have the right to sublicense others
under the rights granted herein and under any technology it develops, but only
in the FIELD OF USE. MAXON shall have the right to approve or disapprove of a
potential licensee, but shall only exercise its right to disapprove if it has a
valid business reason to do so. No royalties from such licensees shall be paid
by INTERNATIONAL to MAXON. Sublicensees of INTERNATIONAL shall be made aware of
and bound by all relevant terms of this Agreement.

       6. IMPROVEMENTS AND ADDITIONAL DEVELOPMENTS. In the event that
INTERNATIONAL or any of its sublicensees shall, during the term of this
Agreement, make or acquire improvements or additional developments, whether
patentable or otherwise, which relate, either directly or indirectly, to the
PROPRIETARY INFORMATION, INTERNATIONAL and/or its sublicensees shall use their
or its best efforts to disclose any such improvements or additional developments
to MAXON in sufficient time for a U.S. and/or foreign patent application to be
prepared and filed on same prior to its first public use, offer for sale or
other public disclosure. It is understood and agreed that such improvement or
additional developments shall be the sole property of MAXON and that
INTERNATIONAL and its sublicensees agree to take whatever steps are necessary to
perfect MAXON's ownership of such improvements or additional developments. It is
further understood that any such improvements

                                   - 3 -


or additional developments shall be automatically made a part of this Agreement
and, as such, subject to all of the terms and conditions hereof. Thus, if such
improvements or additional developments are made or acquired, it is understood

and agreed that INTERNATIONAL shall have the right to use and sublicense any
such improvements or additional developments in the FIELD OF USE and MAXON shall
have the right to use or license such improvements outside the FIELD OF USE.
Whether INTERNATIONAL's right to use any such improvements or additional
developments is exclusive or non-exclusive shall be determined by the nature of
the license granted under Paragraph 2 hereof. Accordingly, as long as the
license granted under Paragraph 2 remains exclusive, INTERNATIONAL's right to
use any such improvements or additional developments shall be exclusive. If,
however, the license granted under Paragraph 2 becomes non-exclusive for any
reason whatsoever, INTERNATIONAL's right to use any such improvements or
additional developments shall be or become non-exclusive also. MAXON's ownership
of any improvements or additional developments relating to the PROPRIETARY
INFORMATION made or acquired by a sublicensee of INTERNATIONAL shall be made an
express condition of any and all sublicenses that may be granted by
INTERNATIONAL. Notwithstanding any of the foregoing, any licensee which develops
or contributes to an invention as an inventor or co-inventor shall have the
royalty-free right to use same upon termination of this Agreement.

       7.    SECRECY

       (a) INTERNATIONAL hereby covenants and agrees that all information
relating to the PROPRIETARY INFORMATION or any of the improvements or additional
developments defined in Paragraph 6 above made known to INTERNATIONAL or any of
its sublicensees pursuant to this Agreement, shall be maintained in confidence
and secret and shall be made known only to those employees, agents, servants,
representatives or sublicensees of INTERNATIONAL who have signed this Agreement
or have signed a separate written agreement wherein such employees, agents,
servants, representatives or sublicensees agree that they will not disclose any
of such information to anyone except other employees, agents, servants,
representatives or sublicensees of INTERNATIONAL who have agreed in writing to
keep such information in confidence. Further, all disclosure to employees,
agents, servants, representatives or sublicensees of INTERNATIONAL shall be on a
strictly need-to-know basis for the sole purpose of supplying such employees,
agents, servants, representatives or sublicensees with sufficient information
concerning the PROPRIETARY INFORMATION or any of the improvements or additional
developments defined in Paragraph 6 to further the objectives of this Agreement.
This obligation to keep information in confidence shall survive termination of
this Agreement for any reason whatsoever.

       (b) The provisions of the preceding subparagraph shall be applicable
except to the extent that any disclosed information has become generally
available and known to the public other than through a breach of confidentiality
by INTERNATIONAL or any of its employees, agents, servants, representatives or
sublicensees.


                                   - 4 -


       8. Procurement of Patents. To the extent that any of the PROPRIETARY
INFORMATION or any of the improvements or additional developments defined in
Paragraph 6 above constitutes a patentable invention, MAXON, in its sole
discretion, shall have the right to determine whether it will file U.S. and/or
foreign patents applications on any such invention, it being understood and

agreed that the costs incurred in connection with the preparation, filing,
prosecution and maintenance of any such application or applications and any
patents issuing thereon will be borne by MAXON. In the event that MAXON decides
to abandon a patent application which it has filed or any such invention, or
decides to permit a patent which has issued thereon to lapse, MAXON will use its
best efforts to provide INTERNATIONAL with an opportunity to maintain any such
patent application or patent. Upon the issuance to MAXON of a patent on any such
invention, INTERNATIONAL and/or its sublicensees shall, upon receiving written
notice from MAXON, mark all products and/or machinery covered by such patent,
the packages and containers in which they are sold and shipped and all
advertisements, literature and/or other promotional materials relating thereto
in such manner as MAXON may reasonably require in conformity with the applicable
patent laws of any country covered by this Agreement in order to give notice
that such products are covered by such patent. If MAXON decides not to file a
U.S. or foreign patent application on any such invention, MAXON shall endeavor
to use its best efforts to provide INTERNATIONAL sufficient notice and time
within which to file a patent application in the U.S. or any foreign country on
same, in its own name, it being understood and agreed that the costs incurred in
connection with the preparation, filing, prosecution and maintenance of any such
application or applications and any patents issuing thereon will be borne by
INTERNATIONAL. If INTERNATIONAL decides to abandon any such patent application
which it has filed on any such invention or decides to permit a patent which has
issued thereon to lapse, INTERNATIONAL will use its best efforts to provide
MAXON with an opportunity to maintain any such patent application or patent.
Upon the issuance to INTERNATIONAL of any patent on any such invention, MAXON
and any of its other licensees shall, upon receiving written notice from
INTERNATIONAL, mark all products and/or machinery covered by such patent, the
packages and containers in which they are sold and shipped and all
advertisements, literature and/or other promotional materials relating thereto
in such manner as INTERNATIONAL may reasonably require in conformity with the
applicable patent laws of any country covered by this Agreement in order to give
notice that such products are covered by any such patent. MAXON's and its other
licensee's rights in patents obtained by INTERNATIONAL in its own name shall
terminate upon termination of this Agreement.

       9.    ENFORCEMENT OF PATENTS

       (a) In the event of any infringement by a third party of any patent or
patents issuing to MAXON on the PROPRIETARY INFORMATION or on any of the
improvements or additional developments defined in Paragraph 6 above, MAXON, in
its sole discretion, shall have the right to commence an action for such
infringement, to select counsel of its own choice and to control the prosecution
of such action. It is understood and agreed that should MAXON commence any such
action for patent infringement, all legal fees and expenses associated with such
action shall be borne by MAXON and MAXON shall be entitled to receive all
damages or other recovery obtained as a result of such action. It is further
understood and agreed, however,

                                   - 5 -


that INTERNATIONAL and/or any of its sublicensees shall, without charge, fully
cooperate with MAXON in the prosecution of any such action to the extent of
providing technical advise and testimony, if necessary, and executing and

Producing any necessary documents, it being understood that any such cooperation
on the part of INTERNATIONAL and/or any of its sublicensees shall not entitle
INTERNATIONAL and/or its sublicensees to any of the damages or other recovery
obtained as a result of such action.

       (b) In the event of any infringement by a third party of any patent or
patents issuing to INTERNATIONAL and/or any of its sublicensees on improvements
or additional developments defined in Paragraph 6 above, INTERNATIONAL and/or
its sublicensees shall have the sole right to commence an action for such
infringement, to select counsel of their own choice and to control prosecution
of such action. It is understood and agreed that should INTERNATIONAL and/or any
of its sublicensees commence any such action for patent infringement, all legal
fees and expenses associated with such action will be borne by INTERNATIONAL
and/or its sublicensees and INTERNATIONAL and/or its sublicensees shall be
entitled to receive all damages or other recovery retained as a result of such
action. It is further understood and agreed, however, that MAXON shall, without
charge, fully cooperate with INTERNATIONAL and/or its sublicensees in the
prosecution of any such action to the extent of providing technical advise and
testimony, if necessary, and executing and producing any necessary documents, it
being understood and agreed that any such cooperation on the part of MAXON shall
not entitle MAXON to any of the damages or other recovery obtained as a result
of such action.

       10.   TERM AND TERMINATION

       (a) This Agreement shall continue in perpetuity or until all of the
PROPRIETARY INFORMATION becomes public and there are no further outstanding
PATENT RIGHTS. In the event of termination for the latter reason, INTERNATIONAL
shall have the option to continue to use the TRADEMARKS at no cost to it. It is
assumed that the TRADEMARKS will, over the years, acquire a valuable secondary
meaning and goodwill with the public to the extent that they will at such time
be commercially important. Thus, INTERNATIONAL reserves to itself the option to
exclusively use and sublicense the TRADEMARKS for products in the FIELD OF USE
in perpetuity. It is understood that there is no obligation on the part of
INTERNATIONAL to exercise its option to continue to use the TRADEMARKS. This
option may only be exercised within 60 days of termination of this Agreement by
a written notification to MAXON signed by the duly authorized officers of
INTERNATIONAL.

       (b) This Agreement and the license granted hereunder may be terminated by
MAXON, in its sole discretion, at any time if:

             (i)  INTERNATIONAL and/or any of its sublicensees shall fail or
                  omit to perform any of the terms of this Agreement including
                  specifically the payment of the fees and/or royalties on the
                  terms set forth in Paragraph 3 hereof and Exhibits B and D
                  hereto, and shall fail to correct any such

                                   - 6 -


                  failure or omission within 30 days of having received written
                  notice from MAXON specifying the nature of the default and the
                  basis for termination; or


             (ii) INTERNATIONAL becomes insolvent, or is adjudicated bankrupt,
                  or a receiver of the business of INTERNATIONAL is appointed,
                  or INTERNATIONAL makes an assignment for the benefit of
                  creditors, or a petition under Chapter 11 of the Bankruptcy
                  Act is filed on behalf of INTERNATIONAL.

       (c) This Agreement and the license granted hereunder may be terminated by
INTERNATIONAL, in its sole discretion, at any time-upon giving MAXON 90 days
written notice of its intention to terminate. If the license granted hereunder
is exclusive when such notice is given by INTERNATIONAL, the license will become
non-exclusive immediately upon the giving of such notice.

       (d) The termination of this Agreement shall in no way affect the
liability and obligation of INTERNATIONAL to pay any sums of money in accordance
with the terms and conditions herein set forth, up to and including the date of
such termination, and shall be without prejudice to any right or rights of
action or remedies of MAXON for the recovery of any monies due or claimed to be
due hereunder. More particularly, the termination of this Agreement will not
release INTERNATIONAL and/or any of it sublicensees from the obligation to pay
any sum which they may owe to MAXON for any and all sales of products or
services covered by this Agreement resulting from sales which were invoiced but
not filled prior to such termination.

       (e) In the event of the termination of this Agreement for any reason
whatsoever, INTERNATIONAL and/or any of its sublicensees shall promptly return
to MAXON or, if MAXON so chooses, will destroy all information in their
possession relating to the PROPRIETARY INFORMATION or any of the improvements or
additional developments defined in Paragraph 6 above, except for PROPRIETARY
INFORMATION developed by INTERNATIONAL and/or any of its sublicensees. It is
further understood and agreed that upon the termination of this Agreement,
INTERNATIONAL and/or any of its sublicensees shall immediately cease and desist
from using the TRADEMARKS and any of the PROPRIETARY INFORMATION or any of the
improvements or additional developments defined in Paragraph 6 above except to
the extent that INTERNATIONAL or any of its sublicensees has developed such
improvements or additional developments in which event INTERNATIONAL or such
licensee shall retain a royalty-free right to continue to use such PROPRIETARY
INFORMATION.
