Dear CME Group Class B-1 Member:

Please visit my website at for information on my candidacy for your representative on the CME Group Board of Directors.

Enclosed in this letter are two pieces of information relating to my candidacy. The first is a page of quotations from other financial industry participants regarding my background and qualifications. The second is a piece I wrote on the value of the liquidity provided by the membership at CME Group.

Like many of you, I spent most of my career trading at the CME. I am a B-1 member, a shareholder, and a knowledgeable investor in this industry. Also like you, I have watched the downward trend in valuation for the B-1 membership over the last several months and would like to see that trend reversed. If you vote for me, you will be voting for an experienced trader who has developed additional skills and a knowledge base beyond trading that can bring value to the CME, its shareholders and its members.

If you would like to discuss the information in this letter or my candidacy for the board, please feel free to contact me directly at or 847-374-3865. I also encourage you to visit my website at

I would very much appreciate your vote and your support in this election.
