Dear B2 (IMM) Shareholder,

During the past two years that I have served on the Board of Directors of
the Chicago Mercantile Exchange we have experienced dramatic changes to our
business. The CME has chosen to evolve and adapt to the changing landscape
to take advantage of the future and maximize shareholder value. Opportunity
and innovation will continue to be the backbone of the CME. I have given
input and pushed to point the CME in this direction with the underlining
goal of achieving long-term growth of our products.

The key strengths of the CME lie in two major areas: Clearing and the pool
of liquidity providers that we have on the floor. With the various counter
party defaults and credit worthiness issues that are appearing in today's
business circle, it casts a bright light onto our Clearing House and
Clearing 21 software. Our large pool of liquidity providers facilitates
risk to be transferred with speed and efficiency. The combination for these
two make an excellent base to build on.

I want the CME to be much more than the pre-eminent processing plant for
futures trading. We need to continue the innovation of new products. This
creativity will bring opportunity for growth in providing "value" in new
markets and new ideas for our customers. This type of innovation will be a
strong competitive advantage in our business arena. We must insure that our
innovation is not stifled or we may be destined to be viewed as a utility
company.

The critical issue at hand is assuring that the CME's position is to allow
a fair competition for the venue where our products will trade in the
future. The covenants approved by our shareholders, from our demutalization
vote, states that this is to be done by supporting each platform with the
needed resources to actively function. To make predetermined assumptions
about open outcry is wrong. It is imperative that we have a Darwinist
"survival of the fittest" environment between the floor and electronic
trading. No one knows when or even if a floor may become obsolete. The
market will definitely tell us what to do, as it plays no favorites. We
must allow for natural selection to occur for the evolution of the
healthiest and strongest platform to emerge and the move to embrace it. Be
it open outcry, computer or hybrid.

Don't underestimate the value of the liquidity that is provided by our
local population. For the CME to achieve a dominant position in risk
transfer going forward, it is crucial that we have these market makers
continue to participate in the liquidity process. I would be against a
forced migration to the screen trade and to increase the costs of the
speculator is a monumental mistake. Locals are able to make tight markets
in a cost-effective way currently in the open outcry platform. Our products
are only as good as the depth and size of volume that is in each market at
each tick. Management must keep the liquidity provider's cost the same if a
move occurs to the electronic platform.

I am the only local on the Clearing House Risk Committee this past year,
assuring that management gets a different view on some issues. My
undergraduate degree in finance has helped immensely as we look at complex
financial models for the CME's future in the form of strategic and business
models. My strong understanding of accounting has also been invaluable, as
the Board regularly debates issues regarding our balance sheet, future
capital expenditures, and potential business ventures. I have the skill
sets that are needed for a Board member to really contribute and make a
difference in a progressive CME. I hope to continue to work for you on the
Board with your support.

                                            Sincerely,


                                           /s/ Patrick Lynch
                                           Patrick B. Lynch
