CME Group Statement to Clarify Erroneous Crain's Chicago Business Article

Thu Mar 06 2008

CHICAGO, March 6 /PRNewswire-FirstCall/ -- In an article today, it was reported that CME Group Executive Chairman Terry Duffy and Vice Chairman Charlie Carey rejected a settlement offer from the Chicago Board Options Exchange (CBOE). This is untrue. As this is a class action lawsuit, only the class and the lawyers representing the class are able to accept or reject any potential settlement offers.

CME Group remains committed to its efforts to preserve the rights of Chicago Board of Trade (CBOT) members to become or remain exercise members of the CBOE pursuant to the exercise right and to share equally in any CBOE demutualization.

The dispute between the class of CBOT members and CBOE is over the 1972 charter and subsequent agreements that gave CBOT members the right to trade and maintain an equity stake in the CBOE.
