Filed by CBOT Holdings, Inc. Subject Company--CBOT Holdings, Inc. Pursuant to Rule 425 under the Securities Act of 1933 File No. 333-72184 * * * * The following communication was distributed to CBOT members on January 18, 2002. The Board of Directors of the Chicago Board of Trade at a special meeting held Thursday, January 17, 2002, took the actions summarized below. . . . Reviewed the CBOT(R) Restructuring as it is proposed to be submitted for approval by the CBOT membership, specifically with reference to stock transfer restrictions for CBOT Holdings, Inc. As previously proposed, the common stock of CBOT Holdings, Inc. would be subject to a complete restriction for the first 270 days following distribution to CBOT members. Thereafter, this transfer restriction would be removed in percentage increments over time until it was completely removed 811 days after distribution. (The restrictions would not apply if the stock was transferred together with the associated Class B membership and, to the extent applicable, the Class C membership.) The Board approved the following modifications to these stock transfer restrictions: - - The stock and the associated Class B membership could only be transferred together, for an indefinite period. This provision would remain in effect unless and until removed by authorization of the Board of Directors. (The Class C membership, if applicable, would be excluded from these transfer restrictions.) This change is designed to give the Board the greatest possible flexibility in determining the stock/membership "decoupling" to maximize shareholder value. -MORE- 01/17/02 -2- The Board's vote on this matter was 10 "Aye" and 4 "Nay", recorded as follows: Director Cahnman Nay Director McMillin Aye Cashman Aye Niciforo Nay Cermak Aye Thompson Aye Corvino Aye Wallace Aye Curley Aye Walter Nay Kurzydlo Aye Weems Aye Levin Nay Vice Chairman Carey Aye While CBOT Holdings, Inc.
