                  A.  General.  Subject to the terms and conditions set forth in
this Agreement, and further subject to the delivery and payment to Licensor by
Licensee of the consideration in support of this Agreement ("License Fee"),
Licensor hereby grants Licensee an exclusive license to use and practice the
Proprietary Rights in the Technology in the Territory during the Term (as
hereinafter defined) of, and for the permitted uses (the "Uses") set forth in
Exhibit A-1 of this Agreement. Licensee shall have the right to sublicense its
rights under this Agreement, but as a condition to any sublicense, each such
sub-licensee shall agree to be bound by the terms and conditions set forth
herein. Licensee shall be primarily liable for the acts of each of its
sub-licensees. Notwithstanding, the foregoing Licensee shall not be liable for
any acts or omissions of its sub-licensees to the extent such acts or omissions
were performed or omitted pursuant to directions, orders, instructions,
recommendations or supervision of Licensor. Licensor agrees to license to
Licensee, on the same terms and conditions contained in this Agreement, any
patent that Licensor may obtain with respect to the Technology that is
enforceable in the Territory.

                  B.  License Fee. Licensee shall pay to Licensor a continuing
monthly License Fee equal to seven (7%) percent of the Licensee's gross revenues

under this Agreement for each month during the term of this Agreement.

             3. License Scope. Licensee's license hereunder is exclusive in the
Territory for the Uses stated in Section 2, and Licensor shall not grant further
licenses for any Use of the Technology in the Territory to any other third
party, except as provided in Section 13. No Proprietary Rights granted under
this Agreement will be marketed directly or indirectly by or under the authority
of Licensee outside the Territory or by Licensor inside the Territory. Licensee
shall not knowingly make any use of the Technology which is not a permitted Use
or which would violate local law. Provided further, the Licensor and Licensee
acknowledge that the Territory for the Uses granted under this License Agreement
automatically expand in scope as provided in Section 1.H hereof, during the Term
of this License Agreement.

           4.     Ownership and Improvements.

                  A.         Licensor as Sole Owner. Licensee acknowledges and
agrees that it does not now own, nor will it obtain any interest in, the
Proprietary Information, Proprietary Rights or the Technology except for the
license granted herein.

                  B.         All Improvements Assigned to Licensor. Licensee
acknowledges and agrees that all Improvements with respect to the Licensor's
Proprietary Information, Proprietary Rights or the Technology which are based in
any way on the Licensor's Proprietary Information, Proprietary Rights or the
Technology, or any Improvement thereto shall be the exclusive property of
Licensor. Licensee agrees to assign, and does hereby assign, and agrees to cause
each of its Affiliates and sub-licensees to assign to Licensor any and all
right, title, and interest it may obtain in any such Improvements, including but
not limited to, any and all applications for Letters Patent and all divisions,
renewals, continuations and continuations-in-part thereof, and all Letters
Patent of the United States which may be granted thereon and all reissues and
extensions thereof, and all rights of priority under international conventions
and applications for Letters Patent which may hereafter be filed for such
Improvements in any country or countries foreign to the United States, and all
Letters Patent which may be granted for such Improvements in any country or
countries foreign to the United States and all extensions, renewals, and
reissues thereof. Licensor agrees to license, and does hereby license, without
further consideration to Licensor, all such Improvements to Licensee pursuant to
the terms and conditions of this Agreement.

                  C.         Cooperation. Licensee agrees to communicate to
Licensor, in writing and promptly upon becoming aware thereof, any facts known
to Licensee respecting the Licensor's Proprietary Information, Proprietary
Rights and the Technology, and all Improvements thereto, and testify in any
legal proceedings, sign all lawful papers, execute all divisional, continuing
and reissue applications, make all rightful oaths and in general do everything
possible to cooperate to effectuate the terms of this Section 4, all at
Licensor's expense.

                  D.         No Challenge to Ownership. Except in asserting
rights granted hereunder, each party agrees not to take any action challenging
or opposing, on any grounds whatsoever, the ownership of any Proprietary
Information, Proprietary Rights, Technology, Improvements, intellectual property
rights of the other party therein, or the validity or enforceability thereof.

        5.        No Restriction on Competition. Nothing in this Agreement shall
be deemed to prohibit Licensee from developing, making, using, marketing or
otherwise distributing or promoting any proprietary rights competitive with the
Technology licensed hereunder, provided that:

                  i)         Licensee does not breach any provision of Section 9
or disparage the Proprietary Rights licensed hereunder in doing so; and

                  ii)        Licensee will use its reasonable best efforts to
primarily promote, market, and use the Technology.

        6.        Representations and Warranties of Licensor. Licensor hereby
makes the following representations and warranties as of the date of this

                       hereunder belonging to any other person or firm.

        7.        Representations and Warranties of Licensee.

                  A.  Organization and Power of Licensee. Licensee is a
corporation duly incorporated, validly existing and in good standing under the
laws of the state of Nevada with all necessary corporate power and corporate
authority to execute this Agreement, perform its obligations hereunder and
conduct its business and own its properties as presently conducted and owned.

                  B.  Authority Relative to this Agreement. The execution,

statute, rule, regulation or prohibition imposed by any regulatory authority
making it illegal for Licensee to consummate the transactions contemplated by
this Agreement.

        8.        Patent Matters.

                  A.         Patent Applications. Licensor retains the sole
right and discretion to file and prosecute patent applications and maintain
patents in the Territory relating to the Proprietary Rights or any Improvements
made by Licensor. At Licensee's request while Licensee remains an exclusive
licensee hereunder, Licensor will discuss its decisions on these matters with
Licensee, but Licensee will not attempt to file or prosecute any such patent
applications or maintain any such patent (i) except as Licensor may, in its sole
discretion, approve in writing, and (ii) except that Licensee may continue
maintenance of licensed patents issued in the Territory if Licensor elects not
to do so. Any improvements to Technology (whether or not patentable or
copyrightable) that are developed by either party shall be owned solely by
Licensor. Each party shall have the right, at its own expense, and solely in its
own name, to apply for, prosecute and defend its Proprietary Rights. Licensor's
existing relevant patents and patent applications in the United States of
America and the Territory are listed on Exhibit "B".

                  B.         Patent Infringement. If Licensee becomes aware of
any product or activity of any third party that involves infringement or
violation of any Licensor patent or other Proprietary Right with respect to the
Technology in the Territory, then Licensee shall promptly notify Licensor in
writing of such infringement or violation. Licensor may in its discretion take
or not take whatever action it believes is appropriate; if Licensor elects to
take action, Licensee will fully cooperate therewith at Licensor's expense. If
Licensor does not, within 90 days after receipt of such a notice of a patent
infringement or other infringement or violation within the scope of the
exclusivity of Licensee's license hereunder, commence action directed towards
restraining or enjoining such patent infringement, Licensee, so long as it is an
exclusive licensee hereunder, may take such legally permissible action as it
deems necessary or appropriate to enforce Licensor's patent or other rights and
restrain such infringement or violation. Licensor agrees to cooperate reasonably
in any such action initiated by Licensee including supplying essential
documentary evidence and making essential witnesses then in Licensor's
employment available. As part of such cooperation, Licensee may join Licensor as
a party, if the need arises.

                  C.         Patent Awards. If Licensor initiates and prosecutes
any such an action under this Section 10, all legal expense (including court
costs and attorneys' fees) shall be for Licensor's account and Licensor shall be
entitled to all of the amounts awarded by way of judgment, settlement or
compromise after deduction of legal expenses. Similarly, if Licensee initiates
and prosecutes such an action, all legal expenses (including court costs and
attorneys' fees) shall be for Licensee's account and Licensee shall be entitled
to all amounts awarded by way of judgment, settlement, or compromise and no
royalties shall be owed Licensor on said sums. Any non-monetary awards shall
inure to the benefit of the Licensor.

                  D.         Patent Searches. Licensee and Licensor understand
that each of the parties has not conducted comprehensive patent searches in the
Territory. Licensor and Licensee agree to work cooperatively regarding issues
concerning patents and Proprietary Rights and similar matters and to exercise
reasonable business judgment in carrying out the objects of this Agreement to
avoid exposing either party to liability under patent or similar laws in the
Territory. Each party represents and warrants that it is not aware of
infringement or potential infringement issues that have not been communicated to
the other in writing before execution of this Agreement.

        9.        Term and Termination.

                  This Agreement will remain in effect until December 31, 2012
("Term"), unless terminated pursuant to this Section.

                  If a party materially breaches a material provision of this
Agreement, the other party may terminate this Agreement upon 60 days written
notice unless the breach is cured within the notice period or if the breach is
incapable of being cured within the notice period the breaching party commences
curative action and diligently prosecutes curative action to completion.
Notwithstanding, the foregoing if Licensee fails to make payments of all License
Fees pursuant to this Agreement and such breach is not cured within thirty (30)
days after written notice of such breach, Licensor may terminate this Agreement.

                  In the event of any  termination of this Agreement, the rights
and licenses granted Licensee under this Agreement and Licensee's obligation
hereunder shall terminate and Licensor's obligations to negotiate or provide
goods, services, facilities, technology or information shall cease but all other
provisions of this Agreement will continue in accordance with their terms. Any
sublicenses surviving termination may be terminated by the granting party in the
same manner as provided in this Section 11 if the other party materially
breaches a material surviving provision of this Agreement. A sublicense will
survive termination and continue according to its terms provided that (i) it was
properly granted, (ii) all the restrictions and limitations of this Agreement
shall apply to the sub-licensee as though this Agreement continued in effect,
(iii) Licensor shall receive all consideration due, if any, in connection with
the sublicense and (iv) in addition to any termination rights under the
sublicense agreement, Licensor shall be entitled to terminate such sublicense on
the same basis as is provided herein for termination of this Agreement.

                  Neither party shall incur any liability whatsoever for any
damage, loss or expenses of any kind suffered or incurred by the other arising
from or incident to any termination of this Agreement (or any part thereof) by
such party which complies with the terms of the Agreement whether or not such
party is aware of any such damage, loss or expenses.

                  Termination is not the sole remedy under this Agreement and,
whether or not termination is effected, all other remedies will remain available.

        10.       Independent Contractors. The parties are independent
contractors and not partners, joint venturers or otherwise affiliated and
neither has any right or authority to bind the other in any way.

        11.       Assignment. The rights and obligations of the parties under
this Agreement may not be assigned or transferred, without the prior written
consent of the other party which consent may be withheld in either party's sole
and absolute discretion.

        12.       Successors and Assigns. This Agreement and all the covenants,
promises and agreements contained herein shall be binding upon and inure to the
benefit of Licensor and Licensee and their respective successors and assigns.

        13.       Infringement. In the event of institution of any suit against
Licensee alleging infringement or misappropriation of any patent or other rights
of a third party by reason of the use of the Technologies or the Proprietary
Rights to the Technology, Licensor agrees, on request of Licensee, made
immediately after institution thereof,

                  (a)  to undertake and diligently conduct, at Licensor's
                       expense, defense of such suit, and

                  (b) to indemnify and hold Licensee and its officers,
                      directors, agents and employees harmless from liability
                      resulting from infringement or misappropriation of any
                      patents, copyrights or other rights and any judgments,
                      awards of damages, settlements, attorneys' fees and
                      expenses which may result therefrom.

Licensee shall render all reasonable assistance to Licensor in connection with
any suit to be defended by Licensor under this Section 16. Licensor shall have
full control of the defense of any such suit, but shall not be free to settle
the same without the consent of Licensee if by the settlement Licensee would be
obliged to make payments, or if the settlement would cause a material impairment
of the ability of Licensee to continue its operations.

        14.       Miscellaneous.

                  A.         Amendment and Waiver. Except as otherwise expressly
provided herein, any provision of this Agreement may be amended and the
observance of any provision of this Agreement may be waived (either generally or
any particular instance and either retroactively or prospectively) only with the
written consent of the parties.

                  B.         Governing Law and Legal Actions. This Agreement
shall be governed by and construed under the laws of the state of California and
the United States without regard to conflicts of laws provisions thereof and
without regard to the United Nations Convention on Contracts for the
International Sale of Goods. The sole jurisdiction and venue for actions related
to the subject matter hereof shall be the California state and U. S. Federal
courts having within their jurisdiction the County of Los Angeles. Both parties
consent to the jurisdiction of such courts and agree that process may be served
in the manner provided herein for giving of notices or otherwise as allowed by
California or federal law. In any action or proceeding to enforce rights under
this Agreement, the prevailing party shall be entitled to recover costs and
attorneys' fees.

                  C.         Headings. Headings and captions are for convenience
