the Escrow Agreement, including but not limited to Paragraph 2 of the Escrow

          (3) become interested in any entity listed on Exhibit A hereto in any

          4.   WAIVER OF CIVIL CODE SECTION 1542.
               ---------------------------------

          The Parties knowingly, voluntarily, intentionally and expressly waive
and

                                      -10-
<PAGE>

relinquish any and all rights and benefits that they have against each other and
each other's predecessors, successors, former, current and/or future assigns,
transferees, attorneys, representatives, agents, officers, directors,
accountants, auditors, affiliates, subsidiaries, partners, shareholders, and
employees under Section 1542 of the California Civil Code, as stated below, or
any other similar provision of any other jurisdiction, including Washington, to
the extent of its similarity. California Civil Code Section 1542 provides:

          A general release does not extend to claims which the creditor does
          not know or suspect to exist in his favor at the time of executing the
          release, which if known by him must have materially affected his
          settlement with the debtor.

          The Parties, and each of them, acknowledge that the foregoing waiver
of the provisions of Section 1542 of the California Civil Code was separately
bargained for.  The Parties, and each of them, knowingly, voluntarily,
intentionally and expressly waive any and all rights and benefits conferred by
Section 1542, or by any law of any state or territory of the United States or
principle of common law that is similar or analogous to Section 1542, to the
extent of such similarity to Section 1542, and agree and acknowledge that this
waiver is an essential term of this Agreement, without which the above-mentioned
consideration and dismissal herein would not have been given.

they have not executed this Agreement in reliance upon any collateral promise,
representation, warranty, or in reliance upon any belief as to any fact or
matter not expressly set forth in this Agreement.  The representations and
warranties of the Parties contained herein shall survive the execution of this
Agreement.
