CHICAGO MERCANTILE EXCHANGE, CHICAGO BOARD OF TRADE
SETTLE WAGNER PATENT LITIGATION

         CHICAGO, Aug. 27, 2002 - Chicago Mercantile Exchange Inc. (CME)
and the Chicago Board of Trade (CBOT) today announced that they have
reached a settlement agreement to resolve the litigation with eSpeed, Inc.
(Nasdaq: ESPD), a subsidiary of Cantor Fitzgerald. The litigation is
related to the Wagner patent on automated futures trading systems (United
States patent No. 4,903,201).

         Under terms of the settlement agreement, CME and CBOT will each
pay $15 million to eSpeed over a five-year period. As part of the
agreement, all companies will be released from the legal claims brought
against each other without admitting liability on the part of any company.
The settlement agreement also covers futures and options on futures on
individual stocks and narrow-based stock indexes offered by OneChicago LLC,
a joint venture of CME, CBOT and the Chicago Board Options Exchange.

         "We made a business decision to settle the case and move on," said
CME Chairman Terry Duffy. "We are now moving forward with our plans for CME
and for investing in improvements to the speed, reliability and
functionality of our GLOBEX(R) electronic trading platform."

         CBOT Chairman Nickolas J. Neubauer added, "Litigation is
time-consuming, expensive and uncertain. It was in the best interests of
the parties to reach a reasonable settlement, and that is what we
accomplished."

         CME will recognize the entire settlement, equivalent to
approximately 28 cents per diluted share, in the third quarter of 2002. CME
will make an initial payment of $5 million, with five subsequent annual
payments of $2 million. The CBOT will recognize the effect of the
settlement in the third quarter of 2002.

         Chicago Mercantile Exchange Inc. (www.cme.com) is the largest
futures exchange in the United States and the second largest exchange in
the world for the trading of futures and options on futures. As an
international marketplace, CME brings together buyers and sellers on its
trading floors and GLOBEX(R) around-the-clock electronic trading platform.
CME offers futures and options on futures primarily in four product areas:
interest rates, stock indexes, foreign exchange and commodities. The
exchange moves about $1.5 billion per day in settlement payments and
manages $27.1 billion in collateral deposits. CME is a wholly owned
subsidiary of Chicago Mercantile Exchange Holdings Inc.

         Providing a diverse mix of financial, equity and commodity futures
and options on futures products, the Chicago Board of Trade offers over 150
years of member-trader expertise, unparalleled liquidity and market
integrity. Via open auction and electronic trading, the CBOT, the world's
third largest derivatives marketplace, provides premier customer service to
risk managers and investors worldwide. Originally a marketplace for
agricultural producers to achieve price protection, today the CBOT offers
more than 60 different products, including futures and option on U.S.
Treasury bonds and notes, interest rate swaps, the Dow Jones Industrial
Average, including an electronic mini-sized Dow, and other Dow Jones
indices. For more information on the CBOT's products and markets, log onto
