Sean O’Hair of the PGA TOUR Shakes Hands with CDW Corporation

New Sponsorship to Place Spotlight on Golf Enhancing Technologies

VERNON HILLS, Ill. - February 20, 2008 - CDW Corporation today announced a long term sponsorship with Sean O’Hair, No. 23-ranked golfer in the U.S. and 2005 PGA TOUR rookie of the year. The partnership expands CDW’s role as the "Official Technology Partner of the PGA TOUR," announced just last month.

"I’m proud to join with CDW in this partnership. As a golfer, I am always working to improve my game and utilizing technology has become a vital resource for me and the PGA TOUR," O’Hair said. "This is a great fit for me because CDW is known for consistent performance and progress, both of which are the ultimate goals in golf and for me."

CDW, a leading provider of technology products and services to business, government and education, will support O’Hair through technologies that can help analyze and advance not only his game, but fan experience as well. As part of the partnership, O’Hair will participate in CDW sponsored events and initiatives throughout the year.

"We are excited to extend our partnership with the PGA TOUR to a one-on-one relationship with Sean O’Hair. Both Sean and CDW share the drive of being a leader in our chosen fields and are consistently looking for ways to improve our performance," said Mark Gambill, chief marketing officer, CDW. "Golf has evolved tremendously through the use of technology and we look forward to supporting Sean as he employs these advancements to augment his game."

CDW launched its five-year sponsorship as the Official Technology Partner of the PGA TOUR in January of this year at the Buick Invitational in San Diego. The company is currently working with the TOUR to enhance its technological capabilities on and off the green. In particular, CDW is working with the TOUR on ways to enhance its SHOTlink scoring technology and make its information even more accessible to fans.

O’Hair turned professional in 1999 after his junior year in high school. Joining the PGA TOUR in 2005, Sean experienced remarkable success from the beginning. In his inaugural year he won the John Deere Classic and finished second at the EDS Byron Nelson Championship, propelling Sean to PGA Rookie of the Year honors. In March 2006 he was the youngest man in the top fifty of the Official World Golf Rankings.

In 2007 O'Hair recorded a top-10 finish at the Verizon Heritage, with a tie for 7th place. His second-round 66 matched his low round for the season. O’Hair is currently ranked 23rd in the United States and 73rd internationally, according to the Official World Golf Rankings.
