Wolf Haldenstein Adler Freeman & Herz LLP Commences Class Action Lawsuit On Behalf Of NYMEX Holdings, Inc. Shareholders

On March 17, 2008, Wolf Haldenstein Adler Freeman & Herz LLP filed a class action in the Court of Chancery of the State of Delaware on behalf of shareholders (including plaintiff Cataldo J. Capozza, an original member and shareholder) of NYMEX Holdings, Inc. (“NYMEX” or the “Company”) (NYSE:NMX), against NYMEX, Richard Schaeffer, certain other directors and officers of the company, and CME Group Inc. (“CME”) for breach of fiduciary duties in connection with the proposed sale of NYMEX to CME.

The case name is Capozza v. NYMEX Holdings, Inc., et al. A copy of the Complaint is available from the Court or can be viewed by clicking on the link at the firm’s website, www.whafh.com.

The complaint alleges that the director-defendants, aided and abetted by NYMEX and CME, breached their fiduciary duties to Mr. Capozza and the other NYMEX shareholders by agreeing to sell NYMEX to CME for grossly inadequate consideration. The complaint also alleges that the proposed acquisition was negotiated through a process that was fundamentally flawed.

According to Mr. Capozza, “I have taken this action to protect all the NYMEX shareholders from the personal self-interest of management. If we sell our shares, we should get a fair and adequate price, not one that rewards Mr. Schaeffer and his cohorts at our expense.” Mr. Capozza added, “I have been a member and shareholder of the New York Mercantile Exchange for more than 25 years, and my concern has always been to see that the members are treated fairly. This proposed sale is the latest instance of management operating for their own interest rather than the best interest of all the shareholders. As a public company, it is more important than ever that management is accountable to all the shareholders.”
