Quixote Corporation Announces Favorable Ruling in Patent Infringement Case

    CHICAGO--February 16, 1999--Quixote Corporation announced today that the United States Court of Appeals for the Federal Circuit has affirmed the jury verdict in favor of Quixote and its formerly owned subsidiary, Disc Manufacturing, Inc. ("DMI"), in a patent infringement lawsuit initiated by Thomson S.A. of France in 1994. Thomson had accused Quixote and DMI of infringing certain patents related to optical disc technology which were subsequently found to be invalid by a Delaware federal court jury in 1996. No specific damages were asked for in Thomson's original suit.
    Philip E. Rollhaus, Jr., Quixote Corporation's Chairman and Chief Executive Officer, commented, "We are very pleased by the court's ruling which fully supports our long-standing belief that Thomson's patents were invalid. This lawsuit was the last material litigation we retained in connection with the divestiture of our previously owned businesses. We look forward to continuing to concentrate our efforts and time on our highway and transportation safety businesses and the opportunities they present to continue Quixote's profitable growth."
    Quixote Corporation, (www.quixotecorp.com), through its wholly-owned subsidiaries, Energy Absorption Systems, Inc. and the TranSafe Corporation, is the world's leading manufacturer of energy-absorbing highway crash cushions, truck-mounted impact attenuators, computerized highway advisory radio transmitting systems, electronic wireless measuring and sensing devices, and other highway safety products and services.
