Component Changes Made To Dow Jones Global Exchange Index

NEW YORK, December 19, 2002 - Dow Jones Indexes today announced that the Chicago Mercantile Exchange (CME) and TSX Group (TSX), which operates the Toronto Stock Exchange, will be added to the Dow Jones Global Exchange Index effective Monday, Dec. 23, 2002.

The Dow Jones Global Exchange Index was created in February 2002 to track the growing number of financial instrument exchanges that are offering their shares to public investors. It is one of several specialty indexes developed by Dow Jones Indexes in response to noteworthy stock market developments.

The addition of CME and TSX raises to 10 the number of exchanges represented in the Dow Jones Global Exchange Index. The indexes base of 100 was set on Dec. 31, 1999, when only two exchanges in the world had sold shares to public investors. Moreover, the CME and TSX are the first two exchanges in the Western Hemisphere to go public.

The index is reviewed quarterly, with changes implemented at the start of trading on the Monday following the third Friday of March, June, September and December.
