owners of shares of Class B-2 common stock of Chicago Mercantile Exchange
Holdings Inc.:

                             P.J. Mulchrone Co.
                            Member CME, IMM, IOM


                                                       Patrick J. Mulchrone
                                                                  President


Fellow Shareholders,

     Once again I write to share my views of the CME and ultimately seek
your support for my reelection to the Board.

     The role of a director has changed. Management now makes decisions we
used to make in committees. The responsibility a director has of looking
out for our member/shareholders best interests has not changed. I find
myself reminding management that until we have an IPO our former members
are our present shareholders. When these shareholder's livelihoods revolve
around the trading floor - management must do a better job of communicating
its vision. Managements' vision will decide where they allocate the
resources we have provided them with.

     I have confidence in our CEO Jim McNulty. He has appeared to have put
together a competent staff. 2001 was an amazingly profitable year for the
CME. This was due almost entirely to Alan Greenspan and the raising of fees
to our floor. Having a year like that, in my opinion, gave Jim McNulty time
to solidify his management team and impart his philosophy on them. 2002
should be the year when he and his team hit stride. We have just announced
the business venture with NYMEX. This is a good first step. While we hope
single stock futures are successful, we may have to look for growth outside
the CME.

     I take pride in being nominated for the sixth time by the IMM, now the
B-2, nominating committee. I own B shares in each division, but make my
living in the Eurodollars. As a member for over 20 years, I both broker and
trade. I understand the issues of all B-2 shareholders and can communicate
and represent them at the Board. You know where to find me and just as
importantly I am accessible. For those of you off the floor, I can be
reached at (630) 323-9872 or e-mailed at pjmulchrone@aol.com. In short,
your interests are my interests.

     My passion and energy level towards our business has not subsided. At
this time, experience is more important than ever. I once again ask for
your support for reelection.


Sincerely,


/s/ Pat
