          for such action, IET shall have the right, at its sole
          discretion, to prosecute such infringement under its sold
          control and at its sold expense, and any recovery obtained
          shall belong to IET.

     10.3 Declaratory Actions

     In the event that a declaratory judgment action is brought against
     IET or Royal by a third party alleging invalidity,
     unenforceability, or non-infringement of the patent rights, IET,
     at its option, shall have the right within twenty (20) days after
     commencement of such action to take over the sole defense of the
     action at its own expense.  If IET does no exercise this right,

     10.2 or 10.3 shall be distributed as follows: (i) each party shall
     be reimbursed for any expenses incurred in the action (including
     the amount of any royalty or other payments withheld from IET as
     described below), (ii) as to ordinary damages, Royal shall receive
     an amount equal to its lost profits or a reasonable royalty on the
     infringing sales, or whichever measure of damages the court shall
     have applied, and Royal shall pay to IET based upon such amount a
     reasonable approximation of the royalties and other amounts that
     Royal would have paid to IET if Royal had sold the infringing
     products, processes and services rather than the infringer, and
     (iii) as to special or punitive damages, the parties shall shares
     equally in any award.  Royal may offset a total of fifty percent
     (50%) of any expenses incurred under paragraph 10.2 and 10.3

     that in no event shall the such payments under paragraph 3 and 4,
     when aggregated with any other offsets and credits allowed under
     this Agreement, be reduced by more than fifty percent (50%) in any
     reporting period.

     which is controlled by the other party, provided that the
     controlling party reimburses the cooperating party promptly for
     any costs and expenses incurred by the cooperating party in
     connection with providing such assistance.

12.  Assignment

     The agreement is personal to Royal and no rights or obligations
     may be assigned by Royal without the prior written consent of IET. 
     A purchase of a majority of Royal's outstanding voting securities
     by a third party without IET's prior written consent shall

     for Royal's breach of certain covenants of this Agreement are not
     ascertainable.  Accordingly, if there is a breach or threatened
     breach of the provisions of section 6 of this agreement, the
     Company shall be entitled to injunctive relief restraining Royal
     from such breach, or to specific performance.  Nothing herein
     shall be constructed as prohibiting the Company from pursuing any
     other remedies for such breach or threatened breach.

14.  Waiver of Breach

     A waiver by IET or Royal of a breach of any provision of this
     agreement by the other party shall not operate or be constructed
     as a waiver of any subsequent breach by the other party.

     of Washington.  This agreement, including the validity hereof and
     the rights and obligations of the parties hereunder and all

     Superior Court and Benton County District Court of the State of
     Washington and the United States District Court for the Eastern
     District of Washington shall have exclusive jurisdiction of all
