(WARSAW, IN) SEPTEMBER 19, 2003 - Zimmer Holdings, Inc. (NYSE: ZMH) announced
today the definitive final results of Zimmer's exchange offer for Centerpulse

subsequent offering period (or additional acceptance period) for each of
Zimmer's exchange offers expired at 4:00 p.m., Central European time, 10:00
a.m., New York City time, on Monday, September 15, 2003.

Based on information provided by Credit Suisse First Boston and Mellon Investor

for Zimmer's Centerpulse offer), an aggregate of 9,006,144 Centerpulse
registered shares and 8,585,666 Centerpulse American depositary shares ("ADSs"),
including 321,201 Centerpulse ADSs subject to guaranteed delivery, were tendered
and not withdrawn in the initial offering period and subsequent offering period.
Based on information provided by Centerpulse, the foregoing shares and ADSs
represent approximately 80.5% and, together with the Centerpulse registered
shares held by InCentive Capital, 98.7% of the issued Centerpulse registered
shares (including shares represented by Centerpulse ADSs).

Based on information provided by Credit Suisse First Boston (the Swiss offer

approximately 99.9% of the issued bearer shares of InCentive Capital.




"Just four months ago, we announced our plan to create an orthopaedics
powerhouse, one with a unique combination of leading market positions, cutting
edge technology and global scale," said Ray Elliott, Chairman, President and CEO
of Zimmer. "We are extremely gratified by the support we have received from the
employees, customers and shareholders of both companies, and look forward to
closing the transaction in just two short weeks."

Based on the results of the mix and match elections in Zimmer's Centerpulse
offer and InCentive Capital offer, holders of Centerpulse registered shares and
Centerpulse ADSs who elected to receive "as many shares of Zimmer common stock
as possible" will receive 3.7947 shares of Zimmer common stock and CHF 112.83

elected to receive "as much cash as possible" will receive CHF 350.00 net in
cash for each tendered registered share and the U.S. dollar equivalent of CHF

shares and Centerpulse ADSs who elected to receive the "standard entitlement" or
who did not make any mix and match elections will receive 3.68 shares of Zimmer
common stock and CHF 120.00 net in cash for each tendered registered share and
0.368 of a share of Zimmer common stock and the U.S. dollar equivalent of CHF

each tendered bearer share.

As previously announced, the exchange of Centerpulse registered shares,
Centerpulse ADSs and bearer shares of InCentive Capital for shares of Zimmer
common stock and cash will take place on October 2, 2003. Shares of Zimmer
common stock to be issued pursuant to the exchange offers have been authorized
for listing on the New York Stock Exchange. Zimmer has applied for a secondary
listing of its shares of common stock on the SWX Swiss Exchange. Zimmer expects
these shares to begin trading on the SWX Swiss Exchange immediately following
the consummation of the exchange offers.

Zimmer intends promptly to initiate the compulsory acquisition process under
Swiss law with respect to both Centerpulse and InCentive Capital. Under the
Swiss compulsory acquisition process, subject to approval by the relevant Swiss
authorities, each Centerpulse registered share (including shares represented by
Centerpulse ADSs) and each bearer share of InCentive Capital that remain
outstanding will be cancelled and converted into the right to receive the
consideration offered in Zimmer's Centerpulse offer and InCentive Capital offer,
respectively.

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. These
statements are not guarantees of future performance and involve risks,
uncertainties and assumptions that could cause actual outcomes and results to
differ materially. These risks and uncertainties include, but are not limited
to, price and product competition, rapid technological development, demographic
changes, dependence on new product development, the mix of our products and
services, supply  and prices of raw materials and products, customer demand for
our products and services, our ability to successfully integrate acquired
companies, control of costs and expenses, our ability to form and implement
alliances, international growth, U.S. and foreign government regulation,
product liability and intellectual property litigation losses, reimbursement
levels from third-party payors, general industry and market conditions and
growth rates and general domestic and international economic conditions
including interest rate and currency exchange rate fluctuations. In particular,
forward-looking statements as to Zimmer's financial and business performance
following the proposed acquisitions should be qualified by the absence of the
opportunity for Zimmer to perform comprehensive due diligence on Centerpulse or
InCentive Capital AG, a significant shareholder of Centerpulse. These forward-
looking statements might have been significantly different had such due
diligence review been undertaken. For a further list and description of such
risks and uncertainties, see the disclosure materials filed by Zimmer with the
U.S. Securities and Exchange Commission. Zimmer disclaims any intention or
obligation to update or revise any forward-looking statements, whether as a
result of new information, future events or otherwise. Readers of this document
are cautioned not to place undue reliance on these forward-looking statements,
since, while we believe the assumptions on which the forward-looking statements
are based are reasonable, there can be no assurance that these forward-looking
statements will prove to be accurate. This cautionary statement is applicable
to all forward-looking statements contained in this document.

This press release is neither an offer to purchase nor a solicitation of an
offer to sell any securities. Any exchange offer will be made only through a
registration statement and related materials. In connection with the exchange
offers, Zimmer has filed registration statements on Form S-4 (each containing a
prospectus/offer to purchase) and a proxy statement on Schedule 14A with the
U.S. Securities and Exchange Commission and submitted Swiss offer prospectuses
to the Swiss Takeover Board. Investors and security holders of Centerpulse,
InCentive Capital and Zimmer are advised to read these disclosure materials
(including other disclosure materials when they become available), because these
materials contain important information. Investors and security holders may
obtain a free copy of the disclosure materials and other documents filed by
Zimmer with the U.S. Securities and Exchange Commission at the SEC's website at
www.sec.gov. The disclosure materials and other documents of Zimmer may also be
obtained from Zimmer upon request by directing such request to Sam Leno, Senior
Vice President and CFO, 574-372-4790.
