BATS EXCHANGE TAKES FLIGHT

Posted October 24, 2008

KANSAS CITY, Mo. – Financial markets technology company BATS Holdings today launched its BATS Exchange, an electronic US equities market.

“This milestone marks a tremendous day for BATS and for our industry,” says Joe Ratterman, Chief Executive Officer of BATS. “We look forward to participating directly in the national market system while competing on a level playing field with our primary competitors, Nasdaq and the New York Stock Exchange.”

BATS launched as an exchange with two active symbols – Aeropostale Inc. (ARO) and Arena Pharmaceuticals Inc. (ARNA). The new exchange plans to be active in all US symbols as of November 6. BATS filed for exchange status in November 2007 and received approval in August 2008. BATS currently matches about 12 percent of daily US equity volume.

BATS also plans to launch a multi-lateral trading facility in Europe on October 31.
