Fri Sep 14 2007

CHICAGO, Sept. 14 /PRNewswire-FirstCall/ -- CME Group Inc. (NYSE/Nasdaq: CME) announced today that Chief Executive Officer Craig S. Donohue has established a stock trading plan in accordance with Securities and Exchange Commission Rule 10b5-1. The plan will enable him to diversify his personal investment portfolio in an orderly, prearranged manner.

Under the terms of the plan, Donohue will exercise options on 17,500 shares of CME Group stock, which an authorized broker will sell over a period of 12 months, beginning in October 2007 and ending in October 2008. The number of shares involved represents less than 15 percent of Mr. Donohue's current holdings of shares and options to acquire shares of CME Group stock.

Mr. Donohue will also exercise additional options and hold the shares received from the exercise during the course of the plan, which will result in his compliance with the company's stock ownership guidelines (ownership of stock valued at five times his based pay) by the end of the plan. He will be in compliance with this plan three years ahead of schedule.

This plan was adopted during an authorized trading period when Mr. Donohue was not in possession of material, non-public information.
