     15.  Arbitration.  Any controversy or claim arising out of or relating to

this Agreement, including, but not limited to a claim based on or arising from
an alleged tort will, at the request of any party be determined by arbitration
in accordance with the Federal Arbitration Act (9 U.S.C. Section 1, et. seq.)
under the auspices and rules of the American Arbitration Association ("AAA").
The AAA will be instructed by either or both parties to prepare a list of judges
who have retired from the Superior Court of the State of Washington, a higher
Washington court or any federal court.  Within 10 days of receipt of this list,
each party may strike one name from the list.  The AAA will then appoint an
arbitrator from the name(s) remaining on the list.  The arbitration will be
conducted from Seattle, Washington.  Any controversy in interpretation or
enforcement of this provision or whether a dispute is arbitrable, will be
determined by the arbitrators.  Judgment upon the award rendered by the
arbitrator(s) may be entered in any court having jurisdiction.  The institution
and maintenance of an action for judicial relief or in pursuit of an ancillary
remedy, does not constitute a waiver of the right of any party, including the
plaintiff, to subject the controversy or claim to arbitration.

     16.  Attorneys' Fees.  In the event any suit or action is brought or an
          ---------------
arbitration or bankruptcy proceeding is initiated (including, without

shall be entitled to reasonable attorney fees in connection therewith.  The
determination of who is the prevailing party and

                                      5.

the amount of reasonable attorney fees to be paid to the prevailing party shall
be decided by the court or courts, including any appellate court, in which such
matter is tried, heard, or decided, including the court which hears any
exceptions made to an arbitration award submitted to it for confirmation as a
judgment (with respect to attorneys' fees incurred in such confirmation
proceedings), or by the arbitrator(s) (with respect to attorneys' fees incurred
prior to and during the arbitration proceedings), as the case may be.

     17.  Relationship of Parties.  The parties are acting herein as independent
          -----------------------

any respect.
