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 August 21, 2003, Zimmer Holdings, Inc. issued the following press release. Zimmer Stockholders Approve the Issuance of Stock in Connection with Zimmer's Exchange Offers for Centerpulse and InCentive Capital Zimmer Highlights Certain Aspects of the "Mix and Match" Election Feature of the Exchange Offers (WARSAW, IN) AUGUST 21, 2003 - Zimmer Holdings, Inc. (NYSE: ZMH) announced today the results of the vote held at the special meeting of Zimmer stockholders in connection with its exchange offers for Centerpulse AG and InCentive Capital AG, a significant shareholder of Centerpulse. Zimmer also today highlighted certain aspects of the "mix and match" election feature in Zimmer's offers. Special Meeting of Zimmer Stockholders Zimmer announced that at a special meeting of stockholders held today in Warsaw, Indiana, its stockholders have voted to approve the issuance of up to 45.4 million shares of Zimmer common stock in connection with Zimmer's exchange offers for Centerpulse and InCentive Capital. Approximately 140 million shares were represented at the meeting (including shares represented by proxies), of which approximately 98% (or 137 million shares) were voted in favor of the proposal. As previously announced, Centerpulse informed Zimmer that the United States Securities and Exchange Commission is conducting an informal investigation of Centerpulse relating to certain accounting issues. Zimmer has been advised by Centerpulse management that Centerpulse is cooperating fully with the investigation, and Zimmer is continuing to conduct its own review of this matter. "We are excited about the potential this combination represents and are equally excited that we enjoy the full support of our stockholders as we move forward to work together with Centerpulse management and employees to create the #1 pure play orthopaedics company in the world," said Ray Elliott, Chairman, President and CEO of Zimmer. The "Mix and Match" Election Feature of Zimmer's Offers In light of certain questions regarding the "mix and match" election feature from Centerpulse and InCentive Capital shareholders wishing to tender their shares into Zimmer's offers, Zimmer also today highlighted certain aspects of the mix and match election feature. As described in Zimmer's prospectuses relating to the Centerpulse offer and the InCentive offer, the mix and match election feature allows tendering shareholders to elect to receive more shares of Zimmer common stock or more cash than the standard entitlement, in all cases, to the extent off-setting elections have been made by other tendering shareholders. For purposes of determining the number of shares of Zimmer common stock and the amount of cash to be received by the tendering shareholders who have elected to receive more shares or cash than the standard entitlement, the assumed value of Zimmer common stock will be CHF 62.50 per share (based on the closing price of Zimmer common stock of US$ 48.28 per share on May 19, 2003, the last trading day prior to the pre-announcement of Zimmer's offers, and the noon buying rate for U.S. dollars on such date of US$ 1.00 = CHF 1.2945). If Zimmer's offers are successful, shareholders of Centerpulse and InCentive Capital will have until the last day of the applicable subsequent offering period for Zimmer's offers (currently expected to be September 15, 2003) to submit their mix and match elections in accordance with the procedures described in the applicable prospectus previously distributed to them. In order to ensure that Zimmer's minimum tender conditions of 66-2/3% (in the case of the Centerpulse offer) and 80% (in the case of the InCentive offer) are satisfied as of the expiration date of Zimmer's offers, which is currently scheduled to be August 27, 2003, shareholders who wish to tender their shares into Zimmer's offers must tender their shares by the August 27 expiration date. Therefore, shareholders who wish to tender their shares into Zimmer's offers but would like to defer their decision regarding the mix and match election to a later date should tender their shares into Zimmer's offers by the expiration date and separately submit the completed mix and match election form prior to the expiration of the subsequent offering period. In addition, shareholders who already have made their mix and match elections may change their elections by completing a new mix and match election form and timely submitting such form in accordance with the procedures described in the applicable prospectus.
