WHO:     3Com Corporation (Nasdaq: COMS) and AmeriCorps*VISTA

WHAT:    In its continued efforts to bridge the "digital divide,"
         3Com has forged a new initiative with AmeriCorps*VISTA to
         support the Urban Challenge Program. The innovative
         collaboration with the Corporation for National Service will
         place AmeriCorps*VISTA members with projects that are awarded
         Urban Challenge grants. As a public/private initiative, this
         alliance will leverage the technological solutions of 3Com's
         digital divide efforts with the people-power of dedicated
         AmeriCorps*VISTA members.

WHEN:    Monday, June 12, 2000

WHERE:   The 68th Annual Conference of Mayors, Seattle

HISTORY: The 3Com Urban Challenge helps to bridge the "digital divide"
         by working directly with U.S. mayors to connect their
         communities and improve access to educational, health care
         and other municipal resources. The program has grown from
         3Com's proven success in implementing networks in urban
         environments such as Boston and San Jose, Calif.

         In January 2000, 3Com presented $1 million in grants of
         networking products and technical consulting services to the
         mayors of 10 U.S. cities that won the company's Urban
         Challenge announced in July 1999 in partnership with the US
         Conference of Mayors. 3Com also announced Urban Challenge
         will extend through the year 2000 to 10 additional U.S.
         cities for a total of another $1 million. Today's
         announcement will provide the next 10 winning cities with the
         people-power of dedicated AmeriCorps*VISTA members with the
         technological solutions of 3Com.

         The 10 cities that received technology grants in January
         from 3Com include Baltimore; Charleston, S.C.; Chaska, Minn.;
         Chester, Penn.; Denver; Glasgow, Ky.; Madison, Wis.; New
         Orleans; Pontiac, Mich.; and Providence, R. I.

         The application deadline for the new round of grants is
         December 1, 2000; grants will be awarded on a rolling basis.
         The winners will be announced at the 69th Winter Meeting of
         The U.S. Conference of Mayors in January 2001. For
