Additional Information About a Pending Transaction

In connection with the proposed business combination transaction between NYSE Group and Euronext, a newly formed holding company, NYSE Euronext, has filed with the SEC a prospectus that also constitutes a definitive proxy statement of NYSE Group (the "NYSE proxy statement/prospectus") and a prospectus that also constitutes a shareholder circular of Euronext (the "Euronext shareholder circular/prospectus"). Both of these documents are included as prospectuses included in the Registration Statement on Form S-4 (File No. 333-137506), as amended (the "S-4") filed with the SEC by NYSE Euronext that also contains additional information and includes the form of an exchange offer prospectus.

NYSE GROUP INVESTORS AND SHAREHOLDERS ARE URGED TO READ THE NYSE GROUP PROXY STATEMENT/PROSPECTUS, AND EURONEXT SHAREHOLDERS ARE URGED TO READ THE EURONEXT SHAREHOLDER CIRCULAR/PROSPECTUS BECAUSE THOSE DOCUMENTS CONTAIN IMPORTANT INFORMATION REGARDING THE PROPOSED BUSINESS COMBINATION TRANSACTION.

You may obtain a free copy of the S-4, the NYSE Group proxy statement/prospectus and the Euronext shareholder circular prospectus (and will be able to obtain the final version of the exchange offer prospectus, if and when it becomes available), and other related documents filed by NYSE Group and NYSE Euronext with the SEC at the SEC's Web site at www.sec.gov. The NYSE Group proxy statement/prospectus and the other documents may also be obtained for free by accessing NYSE Group's Web site at www.nyse.com, or by contacting NYSE Group's investor relations department. The Euronext shareholder circular/prospectus may also be obtained for free by accessing Euronext's Web site at www.euronext.com.

NYSE Group, Euronext and their directors and executive officers and other members of management and employees may be deemed to be participants in the solicitation of proxies from NYSE Group stockholders in respect of the proposed business combination transaction. You can find information about Euronext's and NYSE Group's respective executive officers and directors in NYSE Group's proxy statement/prospectus and Euronext's shareholder circular/prospectus as described above. Additional information regarding the interests of such potential participants have been included in the NYSE Group proxy statement/prospectus and the Euronext shareholder circular/prospectus and in the S-4.

This document shall not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No offering of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the U.S. Securities Act of 1933, as amended.
