Analyst's Summary

--   We are initiating coverage of USinternetworking, Inc. with a 2-1
     rating. The company is expected to record revenues of over $32
     million in 1999, its first full year of revenue-generating
     operations and will likely increase revenues by close to 150% in
     2000.

--   USinternetworking (USi) is defining a new industry segment as an
     application service provider (ASP). USi is a leader in this
     emerging market, which is expected to show explosive growth in
     the next five years.

--   The company is focused on providing a limited number of leading
     applications to its customers. By concentrating on relatively few
     software packages, USi is able to provide expertise in these
     applications and offer customers a high level of support.

--   USi's customers benefit from the company's expertise, allowing
     applications to be implemented much faster than if the customer
     did it internally or with consultants. USi provides users with
     secure, reliable applications at fixed monthly costs.
