     foreign exchange currencies in February 2007 in the $2 trillion OTC
     market.

The 2007 CIO 100 awards will be presented at the La Costa Resort & Spa in Carlsbad, California, on August 21 at the conclusion of the ninth annual CIO 100 Symposium® and Awards Ceremony.

About the CIO 100

The recipients of this year's CIO 100 award were selected through a three-step process. First, companies filled out an online application form detailing their innovative practices in both business and IT. Next, teams of CIO magazine editors and writers reviewed the applications in depth, looking for unique practices and substantial results. Finally, the teams met for a day-long meeting to debate the merits of each nominee and vote on the final 100. Once the top 100 honorees were selected, several honorees were chosen to receive an additional special award.

Complete coverage of the 2007 CIO 100 awards will be in the August 15 issue of CIO magazine and available online at http://www.cio.com/ on August 15.
