                  a $1,000,000 Royalty payable year) falls below $1,000,000,
                  then the Royalty Payable for the single year immediately
                  following will be increased by the difference between the
                  Royalty Payable and $1,000,000 and will become the basis for

            quarter during which royalties are due, Payor will deliver to Payee
            a statement certified by an appropriate officer of Payor which
            accurately sets forth in reasonable detail the Net Revenues From

            will contemporaneously therewith pay any royalties due.

     3.2    Record of Payor. All of Payor's accounting records related to the
            calculations of Net Revenues From Product Sales and the Net Revenues
            From Technology Sales and payment of royalties hereunder shall be
            maintained in accordance with generally accepted accounting

<PAGE>

            relevant records for the calendar quarter covered by the royalty
            statement. Acceptance of any royalty tendered by Payor shall not
            prejudice their rights to contest a royalty statement.

            transfer the title or ownership of the Technology or any party
            thereof, provided, however, that this prohibition does not impair
            Payor's rights to grant licensing agreements so long as in the case
            of an exclusive licensing agreement, such agreement is not the
            substantive equivalent of a transfer of all or substantially all of
            the ownership of the Technology. Any transfer made in violation of
            the foregoing sentence shall be void. Payor shall not transfer any
            commercial quantities of products to any third party or consent to
            such transfer by any licensees, except in transactions for a fair
            market price or in arms length transactions where the value received
            has been established in good faith.

                                   Article IV
                                  MISCELLANEOUS

            directives, if required by Payor, shall be in writing. If, at any
            time, William T. Aldrich, Henry W. Sullivan, and J. Denny Bartell,
            or their successors, as Co-Trustees, unanimously notify the Payor in

            otherwise be distributed to the members of Dune or Thor (as the case
            may be), then Payor may rely on (a) a duly executed copy of the
            Agreement, Plan, and/or Articles of Dissolution of Dune or Thor (as
            the case may be, in the case of dissolution), or (b) a duly executed
            assignment (in the case of distribution) to determine the ownership
            of the rights to receive Royalty. In addition, the members of Dune
            and/or Thor shall each, unanimously, designate among themselves
            representatives, and thereafter Payor shall only be required to rely
            on instructions and directives from such representatives. Payor
            shall have the right to request and rely on instruction from each
            such representative, provided such instructions do not impair the
            rights of any members represented by the other representatives.

     4.8    Integration and Release. This new TieTek Royalty Agreement
            supersedes the Royalty Agreement referenced in paragraph 3 of the
            Recitals and, except for the NATK Royalty Agreement executed
            contemporaneously herewith, any other royalty arrangements or
            agreements involving the Technology, all of which are deemed
            terminated. This Agreement represents the final agreement between
            the parties and may not be contradicted by evidence of prior,
            contemporaneous or subsequent oral agreements by the parties with
            respect to the subject matter of this Agreement. There are no
            unwritten oral agreements between the parties.

            By the execution of this Agreement, Payee releases all claims to
            royalties due under superseded royalty agreements or for any
            breaches of such agreements and acknowledges full satisfaction.

     IN WITNESS WHEREOF, the parties hereto have caused this instrument to be
executed in duplicate by duly authorized persons.
