ROSELAND, NJ, November 9, 2011 – Automatic Data Processing, Inc. (Nasdaq:ADP) today announced that its Board of Directors has promoted Carlos A.

Mr. Rodriguez, 47, has been with ADP since 1999 and has served as President and Chief Operating Officer since earlier this year, responsible for the Company's day-to-day operations. He had previously served as President of several key businesses: National Accounts Services, Employer Services International, and Small Business operations.

Leslie Brun, Chairman of ADP, stated, "Carlos is an extremely talented and experienced executive who has produced strong results in every position he has held at ADP. Over the course of his career, Carlos has shown an exceptional ability to anticipate and meet client needs, build and motivate teams and increase operational efficiencies. With his strategic vision, operating skills and broad management experience at ADP, Carlos will be an ideal leader for this company."

"I am honored and excited that the Board has asked me to lead ADP at such an important time in its development," said Rodriguez. "ADP is extremely well positioned in the marketplace and has many excellent growth opportunities. I look forward to continuing to work with our talented team to build upon our strong momentum and the success we have achieved under Gary's leadership."

Under the succession plan previously established by the Board of Directors, Mr. Rodriguez was to succeed Mr. Butler upon his retirement. Mr. Butler informed the Board yesterday of his decision to retire as CEO and to resign from the Board.

Brun added, "We thank Gary for all the contributions he has made to ADP over the course of the past 37 years and wish him well in his retirement. Since he became CEO in 2006, revenues and profits have both increased significantly and the Company is well positioned to continue its profitable growth."

Butler commented, "I have worked closely with Carlos for the past 12 years and am confident that ADP's employees, customers and shareholders will be in excellent hands. ADP has been my home for over three decades and for that, I am extremely fortunate. I wish all the best to Carlos, the Board and ADP's talented employees as they continue to build this great company."
