Dear        ,

I imagine you have received my letter requesting you vote for me for CME Group B-1 Director. Since we have known each other for so many years on the trading floor I wanted to ask for your vote in a more personal way. I continue conducting my business from the trading floor and miss regular contact with people like you. It is important that the voice of someone as intimately involved with the floor community as I am is heard on board of directors. Your vote is needed and appreciated.

Gary Lark
