NMX Nymex Holdings

Cataldo J. Capozza, an original member and shareholder of NYMEX Holding, Inc. (�NYMEX�) (NYSE:NMX), who filed a class action on March 17, 2008, in the Delaware Chancery Court on behalf of all NYMEX shareholders, announced today that the Delaware Chancery Court has granted expedited discovery in anticipation of a motion to enjoin the proposed sale of NYMEX to CME Holdings, Inc. (�CME�). Capozza is seeking a substantial improvement to the terms of the proposed sale. �Given the record volume on the Exchange in recent quarters, NYMEX should be trading at or near its all-time high. However, our shares are being weighed down by the sharp decline in the price for CME stock,� Capozza said. �If we don�t get an improved deal from CME, I don�t see any way that Chairman Richard Schaeffer and Chief Executive Officer James Newsome can remain in office,� he added.
