3COM/NTT DOCOMO ADVANCE WIRELESS DATA SERVICES IN JAPAN.

3Com Corporation (Nasdaq:COMS), Santa Clara, Calif., and NTT Mobile Communications Network, Inc., (NTT DoCoMo), Japan's largest mobile communications operator has announced a strategic technical and business alliance to develop new wireless services for the Palm Computing Platform. Plans include creating and developing solutions and services to expand the usage of Palm Computing platform devices over wireless networks in Japan. The companies will work to integrate 3Com's world-leading handheld computing and wireless application technologies with NTT DoCoMo's wireless network infrastructure. This joint research and development is intended to bring the benefits of instant remote access to important personal, business and Internet information to an increasing number of Japanese handheld computing users.

For example, 3Com's breakthrough network-independent Web Clipping(sm) technology for wireless Web and intranet access will be optimized for NTT DoCoMo's network to enable delivery of both consumer-level and mission-critical business information to users of wirelessly connected Palm Computing platform products. This announcement is integral with 3Com's strategy to build on its worldwide leadership in the handheld computing industry and enhance the wireless capabilities of the Palm Computing platform through best-of-breed global technology alliances.

"By working with NTT DoCoMo we are ideally positioned to help drive the market for wireless information services and solutions in Japan," said Robin Abrams, president of Palm Computing and senior vice president of 3Com. "Our joint efforts will help insure that our Palm Computing platform is optimized to leverage the power of Japan's largest wireless network infrastructure to bring a great new generation of wireless capabilities to our rapidly growing customer base there."

"The Palm Computing platform is quickly becoming popular in the Japanese handheld computing market. 3Com's strong position in the worldwide handheld industry combined with the openness and extensibility of the Palm Computing platform made them an ideal technology and business partner for us," said Shuichi Shindo, senior vice president, NTT Mobile Communications Network, Inc. "With the great intuitiveness and unequalled functionality of the broad range of Palm Computing platform products, it is clear that the platform is a perfect match for our mobile computing solutions."

The Palm Computing platform continues to gain momentum in Japan. 3Com recently introduced a Japanese language version of the Palm OS(tm) software to enable rapid development and deployment of localized business and consumer applications for Palm Computing platform products. In February of this year IBM released the first product to run on this version of the Palm OS, the Japanese release of the Palm Computing platform-based IBM WorkPad PC companion.

The Palm Computing platform is the foundation for the world's leading family of handheld computing products from 3Com including the Palm III(tm), Palm IIIx(tm), Palm V(tm), and the new Palm VII(tm) connected organizers, in addition to a broad range of products from Palm Computing's strategic partners. These products include the IBM WorkPad PC companion, the Franklin-Covey Electronic DayPlanner, the Symbol STP 1500 with built-in barcode scanning capabilities for vertical markets, and the upcoming pdQ Smartphone from QUALCOMM. Palm Computing platform products already hold a 72 percent share of the worldwide handheld personal companion market (IDC, November, 1998).
