3COM ANNOUNCES SENIOR LEADERSHIP CHANGES TO ACCELERATE
GLOBAL BUSINESS PLAN

Names Robert Mao New Chief Executive Officer and Ronald Sege New President and Chief Operating Officer; Sege Appointed to Board of Directors

MARLBOROUGH, MASS. — April 29, 2008 — 3Com Corporation (NASDAQ: COMS) today announced that the company’s Board of Directors has appointed Robert Mao as the new Chief Executive Officer, replacing Edgar Masri who is leaving the company. Mao will continue to serve on the company’s Board of Directors. The company also announced that it hired Ronald Sege as President and Chief Operating Officer and appointed him to the Board of Directors effective upon his joining the company on April 30, 2008.

“We wish to thank Edgar for his leadership and contributions to 3Com,” said Chairman of 3Com’s Board of Directors, Eric Benhamou. “Edgar helped the company through a challenging period and helped us make progress on a number of fronts, including the successful acquisition of H3C and the development of a differentiated technology strategy with Opens Services Networking, or OSN. We wish him well in his future endeavors.”

To support the company’s increasing emphasis on its growing and profitable China-based H3C operations, Mao will be based in China. Sege will be located in the United States and will focus on 3Com operations outside of China, accelerating the adoption of H3C-developed products in global markets and ensuring the company provides world-class service and support

to its customers and partners around the globe. Sege, who will report to Mao, will also help drive the company’s continued focus on overall profitability and seek to maximize the value of its TippingPoint business as it continues on its path to greater operational autonomy.

“In addition to his 30 years in the global IT and telecommunications industry, Bob’s bi-cultural background, extensive business experience in Asia and fluency in Mandarin and English offer a rare set of skills that can bridge Chinese and western organizations,” added Benhamou. “Bob brings the company a set of skills that are uniquely fitted to 3Com’s current business needs. Having him based out of China and having an experienced leader of Ron’s caliber based in the United States will allow us to speed execution of our global business plan.”

Mao, 64, was most recently 3Com Executive Vice President, Corporate Development from August 2006 to March 2007. Prior to joining 3Com, Mao worked for Nortel Networks, where he was President and Chief Executive Officer of the company’s greater China operations from 1997 to 2006. Prior to his time at Nortel, he was Regional President of greater China for Alcatel. Mao also held senior managerial and technical positions at ITT in Asia and the United States. He holds a master’s degree in material science and metallurgical engineering from Cornell University, and has a master’s degree in management from Massachusetts Institute of Technology (MIT).

“I am extremely excited about this opportunity to help 3Com capitalize on the tremendous potential it has to enhance its position as a global networking leader,” said Mao. “I believe 3Com can leverage H3C as the cornerstone of its future. In less than five years, H3C has built a broad, world-class portfolio of networking, video and storage solutions and gained market share leadership in China. Our objective now is to combine the strength and momentum of H3C with 3Com’s global customer base, well-recognized brand, service and support infrastructure and proven distribution channel. By leveraging these strengths, we will offer customers broad, high-quality, cost-effective solutions on a worldwide basis — this is a compelling value proposition.”

Sege added, “Working with Bob, I plan to accelerate global market penetration for our high-value networking, video and storage solutions, as well as to continue to drive

operational excellence throughout the company. I was attracted to re-join 3Com in large part because of its unique ability to offer customers and partners a differentiated alternative for building future-proof, intelligent networks that deliver real business value to an organization. We have tremendous opportunity ahead of us.”

Before returning to 3Com, Sege, 51, most recently served as President and Chief Executive Officer of Tropos Networks, Inc. a provider of wireless broadband networks, from 2004 to 2008. He is currently on Tropos’ Board of Advisors. Prior to Tropos, Sege was President and Chief Executive Officer of Ellacoya Networks, Inc. a provider of broadband service optimization solutions based on deep packet inspection technology. During his career, Sege also served as Executive Vice President of Lycos, Inc., the internet search engine. He previously spent nine years at 3Com Corporation, from 1989-1998, serving in a variety of senior management roles including Executive Vice President, Global Systems Business Unit. Sege holds an MBA from Harvard University and a BA from Pomona College.
