Wacker Drive, Suite 1108 Telephone: (312) 638-6501 Chicago, IL 60606 Fax: (312) 638-6566 March 17, 2003 Dear Fellow Shareholder, Once again I seek your support for the election to the Board of Directors of the Chicago Mercantile Exchange. Having been away from the Board for several years, my enthusiasm to serve has again become one of my top priorities. The time has come for us to capitalize on our past accomplishments and focus on the future opportunities and profitability of all shareholders. My previous seven years of service as your representative was a greatly rewarding experience. I am proud of the Exchange's accomplishments and my contributions during that period of time. During my service on the Board, I always attempted to be open-minded, logical, rational, and above all, fair. Over the past few years, I have come to recognize that each faction of the Exchange has singular problems that must be addressed separately. My main considerations, however, will be that each problem be balanced against the needs of the enterprise as a whole. I believe that I have unique abilities and drive to balance and harmonize these different interests. My previous service on the Board and many various committees, has given me the experience and leadership qualities required for this position (see attached resume). I pledge to you my time, dedication, and commitment to serving this Exchange. I will continue to live in the city during the week for the term of this directorship. This will make me accessible to you, the shareholder, at any time of day or night. I will also be on the floor everyday and can be reached by phone at 312-638-6501 or by pager at 888-582-3142 at all times. The future profitability of Chicago Mercantile Exchange can only be limited by our own imaginations. I am committed to help discover and develop unique and challenging business opportunities that will benefit all of the shareholders. I encourage you to seek me out, just as I will be contacting you prior to the election, to hear your ideas, concerns, and finally, asking for your support. Respectively, /s/ David J. Wescott David J.
