CME Group Only Financial Exchange Recognized; Acknowledged for Commitment to Career Development and Innovation

CHICAGO, June 27, 2008 /PRNewswire-FirstCall via COMTEX News Network/ -- CME Group, the world's largest
and most diverse derivatives exchange, today announced that it has been
selected by IDG's Computerworld, the "Voice of IT Management," as one of the
top workplaces for information technology (IT) professionals for the fourth
consecutive year. This honor is part of the weekly IT publication's 15th
annual Best Places to Work in IT survey, which was published in the June 30
issue and online at http://www.computerworld.com. CME Group is the only
financial exchange to receive this honor, and was also acknowledged for its
commitment to career development and innovation.

Since 1994, Computerworld's annual "Best Places to Work in IT" feature has
ranked the top 100 work environments for technology professionals, based on a
comprehensive questionnaire regarding company offerings in categories such as
benefits, diversity, career development, training and retention. In addition,
this year Computerworld surveyed more than 30,000 IT workers for the list, and
their responses factored heavily in determining the rankings.

"This award is an acknowledgement of our team and the integral role
technology plays in driving our business performance and future growth," said
CME Group CEO Craig Donohue. "Our CME Globex electronic trading platform
continues to provide access to the most diverse suite of benchmarks products
available on any exchange, and we look forward to continuing to strengthen its
industry leading reputation with the help of our talented team."

"We are extremely proud of our diverse and talented people in technology
at the exchange and the important enhancements they are making to ensure that
CME Globex continues to provide unsurpassed speed, reliability and scalability
to our global client base," said CME Group President Phupinder Gill. "We
remain focused on providing exceptional service to our customers and that
starts with taking care of our employees."

Some of the factors that contributed to CME Group's recognition by
Computerworld included the following:

    -- Electronic trading represents 81 percent of CME Group's total volume to
       date in 2008, versus only 15 percent in 2000.  In that same timeframe,
       average daily volume has grown more than twelve times over from 917,000
       to 12.4 million contracts traded;
    -- CME Group is the only financial exchange in the world that operates
       virtually 24 hours every trading day, which means every aspect of the
       exchange is driven or supported by technology; and,
    -- CME Globex offers global access to the widest range of benchmark
       products across all major asset classes -- a full range of commodity,
       economic event, energy and metal, equity index, foreign exchange,
       interest rate, real estate and weather products.  The exchange's
       technology team is charged with continuously enhancing the system's
       speed, reliability and scalability to support our ongoing growth and
       customer demand.  Recent upgrades to the CME Globex platform have
       reduced CME Globex response times by more than 50 percent, from an
       average of 31 milliseconds down to approximately 13.7 milliseconds.

"The competitive edge sought by the best and smartest companies is no
longer information technology itself," said Scot Finnie, editor in chief of
Computerworld. "After all, IT has permeated the business processes of almost
every department of virtually every enterprise. The new competitive edge is
finding and retaining the very best people to chart and implement your IT
strategy."
