Explanatory Note:
The sole purpose of this revision to the original definitive Proxy Statement filed on June 25, 2007, is to add a Notice of Revocation of Member Proxy, which was distributed to holders of record as of May 29, 2007, of Series B-1 and/or B-2 Memberships in the Board of Trade of the City of Chicago, Inc., on June 30, 2007, by Innisfree M&A Inc., on behalf of IntercontinentalExchange, Inc.


Dear                     :
The CBOT special members’ meeting to vote on the CME deal is scheduled for July 9 at the Union League Club in Chicago. ICE urges all CBOT members to vote against the CME proposal. Among other reasons, voting against the CME deal will allow members to preserve their opportunity to receive (1) a significant premium for any shares of CBOT Holdings common stock they hold; (2) a minimum of $500,000 in value for each of their CBOE exercise rights, without the need for disruptive litigation, if they hold the required interests;1 and (3) pricing protections on trading fees until 2014.
If you have already voted, it is not too late to change your vote. If you are the record holder of your membership interests, you can change your vote in one of three ways:
(1) You can send a written notice stating that you would like to revoke your proxy;
(2) You can complete and submit a new valid proxy bearing a later date by mail or by following the telephone or internet voting instruction provided by CBOT; or
(3) You can attend the members meeting and vote in person.
If you are not sure yet how you want to vote, but want to revoke a vote you have already mailed in, you may send a notice of revocation to CBOT, c/o Georgeson Inc., Wall Street Station, P.O. Box 1100, New York, NY 10269-0646 prior to the members’ meeting, or you may complete the attached “Revocation of Proxy” card and return it to us c/o Innisfree M&A by fax at (212) 750-5799, or by mail at 501 Madison Avenue, 19th Floor, New York, NY 10022 as soon as possible. Innisfree will submit all of the Revocations of Proxy that it receives to CBOT prior to the members’ meeting. If you wish to re-vote after you revoke your proxy, you must follow the voting procedures established by CBOT.
We encourage you to review the proxy statement that ICE distributed to CBOT stockholders. It is available on-line and free of charge at
IntercontinentalExchange, Inc.
1   Contingent on completion of the proposed merger of ICE and CBOT; approval by a majority of CBOT stockholders, a majority of the voting power of CBOT members, and a majority of CBOE members; and obtaining regulatory and judicial approvals.
