MINNEAPOLIS and MOUNTAIN VIEW, Calif. (March 8, 1999) -- WAM!NET Inc. and

bullet         An equity investment in WAM!NET by Silicon Graphics valued at $75
               million in a combination of real estate and cash; in exchange for
               an 8.6% fully diluted equity interest in WAM!NET. Following
               receipt of regulatory approvals, Silicon Graphics will be
               represented on the WAM!NET board of directors. MCI WorldCom made
               an additional $25 million investment consisting of conversion of
               existing debt and $15 million in cash;

bullet         Silicon Graphics will be designated WAM!NET's preferred provider
               of computing systems and related services over the next four

               Industry Smart(TM) solutions are built utilizing Silicon
               Graphics(R) products;

bullet         Silicon Graphics will co-market WAM!NET managed data services
               through their distribution channels and sales force to the
               entertainment market and certain U.S. federal government and

bullet         WAM!NET has also acquired Silicon Graphics' campus and Advanced
