EXPLANATORY NOTE

Zimmer Holdings, Inc. (the “Registrant”) has filed this Post-Effective Amendment No. 4 to Form S-8 Registration Statement (this “Post-Effective Amendment”) to deregister certain securities issuable under the Zimmer Holdings, Inc. TeamShare Stock Option Plan (the “TeamShare Plan”), which were originally registered by the Registrant on a registration statement on Form S-8 (File No. 333-125667) filed with the Securities and Exchange Commission (the “Commission”) and becoming effective on June 9, 2005, as amended by the Post-Effective Amendment No. 1 thereto filed on February 26, 2010, the Post-Effective Amendment No. 2 thereto filed on February 25, 2011 and the Post-Effective Amendment No. 3 thereto filed on February 27, 2012 (the “Prior Registration Statement”).

On February 13, 2009, the Board of Directors adopted, subject to stockholder approval, the Zimmer Holdings, Inc. 2009 Stock Incentive Plan (the “2009 Plan”). On May 4, 2009, the 2009 Plan was approved by the stockholders at the Registrant’s annual meeting of stockholders. The 2009 Plan provides, among other things, that any shares of the Registrant’s Common Stock, par value $0.01 per share (the “Common Stock”) subject to outstanding awards under the TeamShare Plan, that expire, are forfeited or become unexercisable are available for issuance under the 2009 Plan.

As of the date of this Post-Effective Amendment, the total number of shares of Common Stock subject to awards that have expired, were forfeited or became unexercisable under the TeamShare Plan and not yet registered under the 2009 Plan, is 179,516 (the “Newly Available TeamShare Plan Shares”). These Newly Available TeamShare Plan Shares are no longer available for new awards under the TeamShare Plan and will not be issued under the TeamShare Plan.

The Registrant is concurrently filing a separate Registration Statement on Form S-8 to register the Newly Available TeamShare Plan Shares and the newly available shares from another plan for issuance under the 2009 Plan. This Post-Effective Amendment is hereby filed to reflect that, following the date hereof, the Newly Available TeamShare Plan Shares may not be issued under the TeamShare Plan and to deregister the Newly Available TeamShare Plan Shares under the Prior Registration Statement.
