         The following communication was distributed to owners of shares of
Class B-2 common stock of Chicago Mercantile Exchange Holdings Inc. on or
about March 19, 2003:

                            RICHARD (ROCKET) APPEL

                                      DRA

                          A REQUEST FOR YOUR SUPPORT

My name is Richard (Rocket) Appel and I am a candidate for the CLASS B-2 BOARD
OF DIRECTORS SEAT at the Chicago Mercantile Exchange this April 2003.

I wish to take this opportunity to introduce myself to those who I have not
worked with or who do not know who I am and what I feel are the important
issues today and tomorrow at the CME.

CURRENT EVENTS:

While the last two years have been productive with large increase in volume,
most of us who have been here for more than two years know that economies,
markets and business structures change; and not always for the best.

A PRIORITY FOR THE NEXT TWO YEARS SHOULD BE AS FOLLOWS:

1.       WE NEED THE CME TO AID IN THE EXPANSION OF OUR CUSTOMER AND PRODUCT
         BASE. IN OTHER WORDS-WE NEED TO BUILD NEW BUSINESS FOR OUR EXCHANGE.

         The marketing of the CME through our FCM's, direct customer calls,
         and directed advertisement will help to maintain and expand our
         customer base and hold our market share from decreasing to outside
         competitive exchanges who only offer electronic platform trading
         through the premise of lower cost trading. Eagle and Globex side by
         side trading will enable our customers to choose their most efficient
         access to our liquid markets; and advantage that "electronic only"
         markets cannot provide.

2.       WE NEED TO HAVE ON-GOING REVIEW OF OUR FLOOR CONFIGURATION AND USAGE.

         We have heard rumors in the past that some members of our broker
         community always resist change as a function solely for self
         interest. I can only say that if this were wholly true, there would
         be fewer new brokers an potentially some locals who would not have
         the positions they have today.

         The floor community I know has always been adaptive and resourceful
         in its responsibility to change as long as there is merit to the
         changes and the benefits are open to the majority of the
         participants. The problem seems to be that there is not enough direct
         communication between staff and floor to focus on areas of concern
         and as for suggestions or resolution.

         We have a lot of talented people on the floor and they should be
         advised and kept abreast of any major changes. They too are members
         and owners of the new CME.
