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 August 21, 2002. The Board of Directors of the Chicago Board of Trade (CBOT(R)) at its regular meeting Tuesday, August 20, 2002, took the actions summarized below. . . . Considered a report from the Executive Committee and management recommending temporary adjustments in the CBOT(R) pricing structure to be implemented during the 4/th/ quarter of 2002 and in 2003, based on experienced financial results. The adjustments collectively are designed to encourage a deep, centralized liquidity pool to benefit both the open auction and electronic components of the CBOT marketplace, and to encourage additional growth in all Exchange products. The Board acted on these recommendations as follows: 1) For the 4th quarter of 2002 only, waive all trade transaction fees (member and non-member) for open auction and electronic trades in *Dow Jones/SM/ stock index products. (This is a new waiver program.) 2) For calendar year 2003, waive the $0.20 per contract supplemental charge for member open auction trade transactions in *Dow Jones stock index contracts. (This extends a previous waiver program.) 3) For calendar year 2003, waive the $200 per month fee for IDEM badge holders who execute trades in Dow Jones stock index products. (This extends a previous waiver program.) 4) For calendar year 2003, waive the Floor technology/"Floor Efficiency Service" charges for all membership categories. (On a monthly basis, these charges had been $167 for Full Members, $100 for Associate Members and GIMs, and $67 for IDEMs and COMs.) (This extends a previous waiver program.) 5) For calendar year 2003, reduce the member open auction trade transaction fee rate from $0.05 to $0.02 per contract/per side (i.e., waive $0.03 of the established rate). (This is a new waiver program.) -MORE-

-2- The Board approved the foregoing programs unanimously, with the vote recorded as follows: Director Cahnman Aye Director Odom Aye Callahan Aye Sagui Aye Cermak Aye Thompson Aye Corvino Aye Weissman Aye Feiler Aye Filipowski Aye Vice Chairman McMillin Aye Carey Aye 6) From October 1, 2002 through March 31, 2003, with respect to member trade transaction fees, waive the fee for one contract on a/c/e for each contract executed by open auction. The transactions which would qualify for this program are identified as Account Types 1a, 1b, 1c and 1d on the CBOT Account Type schedule. Delegate trades on a/c/e would remain subject to the $0.15 delegate surcharge. This program is designed specifically to facilitate the activities of open auction based liquidity providers, in order to promote efficient and low cost market executions for customers and end users. Eligible members and delegates would claim the applicable fee credits on a monthly basis. Credits resulting from each month's trading activity would have to be claimed within the billing cycle of the following month. An open auction trade in futures would qualify only for an a/c/e fee waiver in a comparably-sized futures contract. An open auction option transaction would qualify only for an a/c/e fee waiver in an options contract. However, the open auction and a/c/e transactions could be in different commodities within the same product complex - Agricultural, Financial or Stock Index - and still qualify for the a/c/e fee waiver. Further details on this program will be forthcoming. The Board approved this new waiver program by a vote of 9 "Aye", 1 "Nay" and 2 abstentions, recorded as follows: Director Cahnman Nay Director Odom Aye Callahan Aye Sagui Aye Cermak Aye Thompson Aye Corvino Abstain Weissman Abstain Feiler Aye Filipowski Aye Vice Chairman McMillin Aye Carey Aye -MORE- 08/20/02
