SAN FRANCISCO--(BUSINESS WIRE)--August 2, 2001

Critical Path, Inc. (Nasdaq:CPTH), a global leader in messaging and directory infrastructure, announced today that Larry Weber and Jeffrey T. Webber will replace Kevin Harvey and George Zachary on its board of directors.

"Both Larry and Jeff contribute the management expertise and deep understanding of the technology industry needed to help drive the company's priorities of growth and profitability," said David Hayden, Critical Path's founder and executive chairman. "We will draw on their wealth of knowledge and experience as we take Critical Path's global business to its next level. This is also a natural time for our original venture investors to transition off the board."

Kevin Harvey of Benchmark Capital and George Zachary of Mohr Davidow, helped guide the company through its early developmental years. Critical Path thanks them for their early vision, their dedication to the company and for the hard work they both put in over the past six months to help the company through its recent crisis.

Larry Weber currently serves as the chairman and chief executive officer of Weber Shandwick Worldwide, the largest public relations firm in the world. In 1987, Weber founded The Weber Group, a technology focused public relations firm based in Cambridge, Mass. Under his leadership, the firm grew to become one of the largest and most established public relations firms in the United States. The Interpublic Group purchased The Weber Group in 1996, and Weber was subsequently named chairman and CEO of Interpublic's Advanced Marketing Services. Weber serves on several boards, including the Museum of Science in Boston, the Massachusetts Interactive Media Council and several technology start-ups including EchoMail, eMaven and Firepond. He holds a bachelor's degree from Denison University, and a master's degree from Antioch College in Oxford, England.

Jeff Webber founded R.B. Webber & Company, and has served as its president since 1991. R.B. Webber & Co. provides strategic planning and consulting services to high technology companies in Silicon Valley. He is an entrepreneur and visionary in his own right, and has served on over 20 public boards throughout his career, including Sagent, Sybase, Commerce One, and AvantGo. He is currently focusing on working with companies where he believes the basic business model and technology, position the company for explosive growth in the aftermath of the technology market correction. Mr. Webber holds a BA degree in American Studies from Yale University.
