Chairman and CEO

May 6, 2014

Dear IMM Member/Class B-2 Shareholder,

I am writing to draw your attention to and seek your support for a great candidate running for the CME Group Board of Directors. Pat Maloney is a long-time member with an IMM seat and is seeking election as a Class B-2 director. He has spent his career on the Exchange floor and also fully appreciates the electronic marketplace which now handles most of the Exchange volume. His career has been marked by an eagerness to listen to all points of view. Those of us who have known him for decades can attest that Pat is a very fair and reasonable man with the utmost integrity.

As Pat’s letter highlights, he views his potential role on the Board as an opportunity to focus on increasing conversation about trading opportunities, expanding the business and generating new client participation. Pat is also extremely concerned about ensuring reasonable costs for all market participants.

I share Pat’s interests and believe he would be a great addition as our Class B-2 director on the CME Group Board of Directors.

Best regards,





231 S. LaSalle St. Suite 1400, Chicago IL 60604
