Mr. Esser will stand for election at the upcoming Annual Meeting of Shareholders to be held on July 23, 2002 at 10 a.m. at a new location, The Hyatt Regency San Francisco, at 5 Embarcadero Center, San Francisco, California.

Mr. McGlashan, 38, a veteran executive from both the corporate world and private equity industry, joined the board of Critical Path in April 2001. He was named chief executive officer in January of this year after leading the company to financial stability. He previously served as the Company's interim president and chief operating officer.

"Bill was the driving force behind the Critical Path turnaround, and he remains the driving force behind a solid management team that is executing well on all fronts," said Raul Fernandez, CEO of Dimension Data North America, and a Critical Path director. "Bill possesses the leadership and vision necessary to build upon Critical Path's solid technology and customer base to create a truly substantial global company."

Prior to joining Critical Path, Mr. McGlashan served as chief executive of technology investment firm Vectis Group LLC, and as a venture partner at Whitney & Co. He previously co-founded and served as president of Pharmanex and was co-founder and CEO of Generation Ventures. Mr. McGlashan is also a Bain Capital and Information Partners alumni. He earned a Bachelor of Arts degree in history at Yale University and a master's degree in business administration from the Stanford Graduate School of Business.

"I'm honored the board has appointed me to serve as Critical Path's chairman," said McGlashan, "and I'm also delighted to add to the board a very talented and experienced leader with extremely relevant business experience."

"Klaus Esser has tremendous expertise in the communications industry and in the European and international corporate markets," said McGlashan. "He provides a unique understanding of the vital role technology plays in global corporations."

An expert on the communications industry, Mr. Esser leads investment activity in Germany for General Atlantic Partners, the global private equity firm and a Critical Path investor.

Mr. Esser is currently chairman of the board of Apollis AG, a developer of mobile applications and services, and is a director of GWI AG, a provider of software solutions for hospitals. He is a graduate of the Sloan School of Management at the Massachusetts Institute of Technology and the LMU law school in Munich.

"Internet communications applications, specifically messaging solutions, are becoming increasing relevant to carriers and service providers as they seek to drive revenues globally," said Mr. Esser. "With its current installed base of market-leading carriers and service providers, Critical Path is well-positioned to take advantage of this trend."
