EBAY STOCKHOLDERS ARE STRONGLY ENCOURAGED TO READ ANY SUCH PROXY STATEMENT (INCLUDING ANY AMENDMENTS AND SUPPLEMENTS) AND ACCOMPANYING WHITE PROXY CARD WHEN THEY BECOME AVAILABLE AS THEY WILL CONTAIN IMPORTANT INFORMATION.

Information regarding the names of eBay’s directors and executive officers and their respective interests in eBay by security holdings or otherwise is set forth in eBay’s proxy statement for the 2013 Annual Meeting of Stockholders, filed with the SEC on March 18, 2013. To the extent holdings of such participants in eBay’s securities have changed since the amounts described in the 2013 proxy statement, such changes have been reflected on Initial Statements of Beneficial Ownership on Form 3 or Statements of Change in Ownership on Form 4 filed with the SEC.
