In addition to the shares of common stock to be sold in the offering by NYMEX, additional shares may be included by existing stockholders who will be afforded the opportunity to sell in the offering. The timing of the initial public offering is dependent upon several factors, including market conditions, regulatory review and approval, as well as NYMEX stockholder approval. As a result, both the Registration Statement and the Proxy will be amended in the future.

The joint book-running managers of the offering are JPMorgan and Merrill Lynch & Co. The co-managers are Bank of America Securities LLC, Citigroup, Lehman Brothers and Sandler O'Neill + Partners, L.P.

A registration statement relating to these securities has been filed with the SEC but has not yet become effective. These securities may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective. This announcement shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of these securities in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of such state.
