CME Statement In Response To ICE's CBOT Shareholder Letter

Date 03/07/2007

CME, the world's largest and most diverse derivatives exchange, has issued the following statement:

"ICE continues to try to play the role of a spoiler in the CME CBOT merger agreement and has offered nothing new to its proposal. Having been rejected by CBOT's board not once but twice, ICE has yet to address the fundamental strategic and operational flaws in its proposed transaction. ICE has also put forward a speculative ERP offer that significantly undervalues those rights and which has not even been approved by CBOE members, let alone the Delaware court or CBOT members. As a result, the only option ICE has is to try to disrupt the CME and CBOT merger. The fact remains that a combined CME and CBOT offers greater long-term value for CBOT shareholders with lower risk, while offering customers of both exchanges significant benefits that ICE cannot match."
