                                  WITNESSETH

      WHEREAS, this Royalty Agreement is entered into pursuant to the Master
Agreement simultaneously entered into between the Parties.

      NOW THEREFORE, in consideration of the mutual covenants and promises
contained herein, the Parties hereto hereby agree as follows:

      1.  DEFINITIONS

          1.1  "Inventions" shall mean the collective methods, apparatus and
proprietary inventions described on "Exhibit A" (which is attached hereto and
incorporated herein by this reference), including the entire right, title and
interest in said Inventions, in any United States disclosure documents and
patent applications and in all divisions, continuations and
continuations-in-part of said applications, all previously filed provisional
applications for which any present applications seek the benefit of an earlier
filing date under 35 U.S.C. Section 119, all reissues or extensions of Letters
Patent or Patents granted thereon, and in all corresponding applications filed
in countries foreign to the United States, and in all patents issuing thereon
in the United States and foreign countries.

               Such shall also include the right to file U.S. and foreign
patent applications on said Inventions in its own name, wherever such right
may be legally exercised, including the right to claim the benefits of the
International Convention for such applications.

          1.2  "Product" shall mean any article which may be offered for sale
by the Company based on or covered by the Company's Inventions.  There can be
no assurance that any Product will ultimately be offered for sale by the
Company based on the technology contained in the Company's Inventions.

          1.3  "Inventor" shall mean the person identified on "Exhibit A" as
the inventor with respect to any Product.

      2.  ROYALTY

          2.1   Amount.  The Company shall pay to Inventor a royalty of 5% of
the gross manufactured cost of the Product invented by such Inventor as
identified and described on "Exhibit A"; provided, however, that if two
persons are identified as co-inventors, each shall receive half of the total
royalty payable with respect to such invention.

          2.2   Payment.  Payment of the royalty is due, and Company shall pay
the royalty to Inventor, on or before the 30th day after each calendar
quarter, for the previous calendar quarter's manufacturing costs, payment
commencing with the first calendar quarter during which manufacturing of
Product has occurred following the offering of such Product for sale to the
public; provided, however, that the Company may offset against such payment
any amounts previously advanced to Inventor pursuant to paragraph 2.3 hereof.

          2.3   Advance Against Future Royalties.  The Company shall, on a
monthly basis, pay to each of the following persons the amount set forth below
as an advance against future royalties payable pursuant to paragraphs 2.1 and
2.2 above:

            Otis H. Sanders            $3,333.00
            David Sanders              $1,333.00
            Daryl Conley               $2,333.00
            Paul Thomas                $1,333.00

             In the event that payment of actual royalties pursuant to
paragraph 2.2 above has not exceeded the advances paid pursuant to this
paragraph 2.3 on or before June 1, 2006, each Inventor shall promptly repay to
the Company an amount equal to total payments to Inventor under paragraph 2.3
less total payments to Inventor under paragraph 2.2; provided, further, the
Company's obligation to pay such advances against future royalties pursuant to
paragraph 2.3 shall immediately terminate at any time if the Company in good
faith determines that it is unlikely, in the twelve months succeeding such
determination date, that actual royalties payable pursuant to paragraph 2.2
will exceed the advances against future royalties payable pursuant to
paragraph 2.3.

      3.   REPRESENTATIONS AND WARRANTIES

          3.1   Absence of Certain Representations.  Company and Inventor
expressly acknowledge and agree that neither has made and neither shall make
any warranty or representation to the other with respect to the quality or
fitness for use for any purpose of:

                (a) any of Company's Inventions or know-how;

                (b) the Product which may be made or used by Company or
Company's affiliates in reliance upon Company's Inventions or know-how;

                (c) the utility of any invention covered by Company's
Inventions or included in Company's know-how;

                (d) the merchantability of any invention covered by Company's
Inventions or included in Company's know-how;

                (e) the fitness of any invention covered by Company's
Inventions or included in Company's know-how for the particular purpose for
which potential customers may intend to use such Products; or

                (f) the validity of patents or patent claims included in
Company's Inventions.

          3.2   Inventor Representations.  Inventor warrants only that:

                (a) he has never had a claim for infringement advanced against
him relative to the Inventions;

                (b) prior to Inventor's assignment to the Company, he was the
owner of all right, title and interest in Company's Inventions;

                (c) he has taken no action known to preclude the Company from
filing for patent rights; and

                (d) workable Products may be fabricated from the technology
underlying Company's Inventions.

      4. TERM

          4.1  Term.  This Royalty Agreement shall continue for the term of
the Company's Inventions.

contemporaneous oral or written representation, understanding, agreement or
communication between the parties concerning the subject matter hereof.

      5.3  Amendments.  All amendments or modifications of this Agreement
shall be binding upon the parties so long as the same shall be in writing and
executed by each of the parties hereto.

      5.4  Waivers.  No waiver of any provision of this Agreement or any
rights or obligations of any party hereunder shall be effective, except

courts of the State of Utah for the County of Salt Lake, or the United States
