    SAN JOSE, Calif. & AACHEN, Germany--(BUSINESS WIRE)--Feb. 24, 2005--Echelon Corporation (Nasdaq:ELON), the creator of the LonWorks(R) device networking platform for networking everyday devices to each other and the Internet and TEMA AG, a leading marketing services company for the European technology market, today announced that Paris, France has been selected as the location for the LonWorld(R) 2005 International Exhibition and Conference. The two-day event will take place from October 20 - 21, 2005 at the Congress Center EuroDisney, Paris. Each year, the LonWorld event is located in a different region to serve the worldwide LonWorks market. This year's event promises to be the largest ever event in Europe, bringing together suppliers, buyers and users of the platform from around the globe.
    "The significant response garnered by the last LonWorld event in Europe, which Echelon and TEMA jointly organized, encouraged us to bring the forum to Paris. Building upon the strength of last year's success in Shanghai, China, this year's event will once again foster the international exchange of technological advancements, allow LonWorks technology-based businesses to meet new trade partners, and to introduce new open products and solutions based on LonWorks technology to a rapidly growing market place," said Grant Mahmutovic, Executive Vice President, TEMA AG.
    According to Mark Ossel, Echelon's general manager and vice-president, EMEA, "LonWorld 2005 has even more significance than prior years as the underlying technology of the LonWorks platform has just been accepted as a preliminary building automation standard by the European Union. We believe that this standardization will drive the LonWorks platform to even greater success in the European and worldwide markets. Working together with TEMA, our distribution partner EBV Elektronik, local user organizations, and LonMark(R) affiliate organizations, we look forward to a great success at LonWorld 2005."
    The LonWorld 2003 event in Munich, Germany, the last European LonWorld event, was the first co-organized by Echelon Corporation and TEMA. LonWorld 2003 exceeded the expectations of the organizers, and surpassed all previous LonWorld events in attracting over 80 exhibitors and 1,450 trade visitors. For the 2005 event, TEMA AG will be responsible for the promotion and organization of the Exhibition, while Echelon will be the organizer of the co-located seminar, the Developers' Conference.
