Filed by Zimmer Holdings, Inc. Pursuant to Rule 425 Under the Securities Act of 1933 Subject Company: Centerpulse AG (Registration No. 333-105561) Subject Company: InCentive Capital AG (Registration No. 333-105562) On September 4, 2003, Zimmer Holdings, Inc. issued the following media release. [ZIMMER HOLDINGS, INC. LOGO] MEDIA RELEASE ZIMMER AND CENTERPULSE ON THE WAY TO WORLD MARKET LEADERSHIP WINTERTHUR OPERATION TO CONTINUE EVEN AFTER CENTERPULSE IS INTEGRATED Zurich, 4 September 2003 - ZIMMER HOLDINGS, INC. HAS ALMOST COMPLETED ITS ACQUISITION OF CENTERPULSE AG. THE TRANSACTION SHOULD BE FORMALLY CONCLUDED AT THE BEGINNING OF OCTOBER. CENTERPULSE WILL THUS BECOME PART OF THE "ZIMMER" GROUP, WHICH AFTER THE INTEGRATION WILL BECOME THE WORLD'S LEADING ORTHOPAEDICS COMPANY, WITH TOTAL SALES OF $ 2.2 BILLION AND A STAFF OF AROUND 7,000. AS ZIMMER CHAIRMAN AND CEO RAY J. ELLIOTT ANNOUNCED IN ZURICH, THE COMPANY WILL CONTINUE TO MAINTAIN ITS PRESENCE IN WINTERTHUR. HE ALSO CONFIRMED HIS EARLIER STATEMENT THAT WINTERTHUR WOULD PLAY AN IMPORTANT ROLE NOT ONLY AS A PRODUCTION SITE, BUT ALSO IN RESEARCH AND DEVELOPMENT AND IN ZIMMER'S MEDICAL TRAINING ACTIVITIES. WINTERTHUR WILL ALSO BE INCLUDED IN THE EVALUATION PROCESS FOR ZIMMER'S EUROPEAN HEADQUARTERS. TO UNDERLINE SWITZERLAND'S IMPORTANCE TO THE INTEGRATED ZIMMER GROUP, ZIMMER WILL BE APPLYING FOR A LISTING ON THE SWISS STOCK EXCHANGE. In Ray Elliott's view the overwhelming approval given by shareholders of Zimmer, Centerpulse and the major shareholder of Centerpulse, Incentive Capital AG, bears testimony to the compelling logic of the Zimmer-Centerpulse merger. The deal opens up exciting new prospects for both companies and secures for the new, integrated firm a leadership position within a market that is consolidating globally. The two companies complement each other extremely well in terms of both markets and products. Together, Zimmer and Centerpulse will be the number 1 firm in the reconstructive implants sector in Europe, the USA, and Japan. To ensure that it maintains its global market leadership, Zimmer will in the future invest around 6% of sales each year - about CHF 200 million - in researching and developing new, innovative products and processes. Zimmer's traditionally high earnings power will continue to be a major priority for Ray Elliott in the new configuration. The combined company in 2002 had earnings before interest, tax, depreciation and amortization (EBITDA) in excess of 30% of sales. In three years, synergies should produce long-term cost savings of $ 70 to $ 90 million a year, and by the end of 2006 Zimmer aims to have paid back all of the debt resulting from the acquisition of Centerpulse. WINTERTHUR RETAINS ITS IMPORTANCE AS A PRODUCTION AND RESEARCH SITE A 30 to 40-person integration team will press ahead with the merger of Centerpulse and Zimmer as soon as the acquisition has been formally concluded. Decisions have yet to be taken about the structure and staffing of the new management organization. However, Max Link, Chairman of the Board and CEO of the current Centerpulse, as well as Beatrice Tschanz, Chief Communication Officer, Urs Kamber, Chief Financial Officer, Matthias Molleney, Head of Human Resources, and General Secretary and Chief Legal Counsel Christian Stambach will officially be leaving the company on the day of the Extraordinary General Meeting to be held on 9 October. In line with Zimmer's corporate policy, the company in Switzerland will continue to be led by a Swiss management. The name of Centerpulse is not being kept. In the future the company will operate under the globally known and successful Zimmer brand. The successful product brands will, however, be retained. SAFE HARBOR STATEMENT This press release contains forward-looking statements based on current expectations, estimates, forecasts and projections about the orthopaedics industry, management's beliefs and assumptions made by management. Forward-looking statements may be identified by the use of forward-looking terms such as "may," "will," "expects," "believes," "anticipates," "plans," "estimates," "projects," "targets," "forecasts," and "seeks" or the negative of such terms or other variations on such terms or comparable terminology.
