ITEM 5.          OTHER EVENTS.

         On October 13, 1997, Metricom, Inc., a Delaware corporation (the
"Company"), announced the execution of a Common Stock Purchase Agreement, dated
as of October 10, 1997 (the "Agreement"), between the Company and Vulcan
Ventures Incorporated, a Washington corporation ("Vulcan"), a copy of which is
attached as Exhibit 99.1.  The Agreement contemplates that, subject to the
satisfaction of certain conditions set forth therein, including the approval
and adoption of the Agreement by the requisite vote of the Company's
stockholders as set forth in the Agreement, the Company would, among other
things, issue and sell 4,650,000 shares of the Company's Common Stock, $0.001
par value per share ("Common Stock"), to Vulcan for $12.00 per share in cash.

         In a separate transaction, Vulcan entered into an agreement by which
it would acquire 2,583,000 shares of Common Stock from Lindner Investments, the
Company's largest stockholder.  The transactions contemplated by the Agreement
and the subsequent agreement with Lindner Investments could result in Vulcan
owning up to 49.9% of the outstanding Common Stock.
