     WESTBORO, MASS., JUNE 10, 1998 - OpenROUTE(R) Networks, Inc., a leading
provider of networking solutions for Internet and Intranet connectivity,
announced today that its shareholders have overwhelmingly approved a proxy

OpenROUTE Networks, Inc. (NASDAQ:OPEN). The announcement was made at the
Company's annual meeting held today in Canton, Mass. OpenROUTE Networks had
been operating as a wholly owned subsidiary of Proteon, Inc. since it was
formed in January of 1997.

     Upon the completion of the necessary filings with NASDAQ, the Securities

State, the Company's stock symbol will change from PTON to OPEN. The actual
date the stock will begin trading on the NASDAQ system as OPEN is expected
to be determined within a week. A press release will be issued with the
official start date for shares to be traded under the OPEN ticker symbol.
Shareholders will also be notified of the change through their brokerage firm
or the Company's transfer agent.

    New stock certificates issued will now bear the name OpenROUTE Networks, 
Inc. Existing Proteon stock certificates will not be re-issued and will be
honored as OpenROUTE Networks stock. The Company has initiated plans to operate
Proteon, Inc. as as wholly owned subsidiary of OpenROUTE Networks, Inc. and 
contines to market its Token Ring network adapter cards and hubs. Shareholders
