Litigation Matters


Other than suits we bring to enforce our patent rights we are not a party to any material pending legal proceedings other than that which arise in the ordinary course of business.  We believe that any liability that may ultimately result from the resolution of these matters will not, individually or in the aggregate, have a material adverse effect on our financial position or results of operations.
