Certain statements contained in this communication regarding matters that are not historical facts are forward-looking statements (as defined in the Private Securities Litigation Reform Act of 1995). These include statements regarding management’s intentions, plans, beliefs, expectations or forecasts for the future including, without limitation, the proposed business combination with Wincor Nixdorf and the offer.

By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that may or may not occur in the future. Forward-looking statements are not guarantees of future performance and actual results of operations, financial condition and liquidity, and the development of the industries in which Diebold and Wincor Nixdorf operate may differ materially from those made in or suggested by the forward-looking statements contained in this document.

These risks, as well as other risks associated with the contemplated business combination, are more fully discussed in the prospectus that is attached as Annex 4 to the German offer document and has been filed with the SEC. Additional risks and uncertainties are identified and discussed in Diebold’s reports filed with the SEC and available at the SEC’s website at www.sec.gov.
