       Pursuant to an Agreement for the sale and purchase of the entire issued
  share capital of Xstreamis Plc ("Xstreamis") dated as of May 26, 2000 (the
  "Agreement") among Tut Systems, Inc., a Delaware corporation ("Tut"), the
  Shareholders of Xstreamis (the "Shareholders"), and Philip Corbishley ("Mr.
  Corbishley"), an individual and former director of Xstreamis, on May 26, 2000
  (the "Closing"), Tut acquired the entire issued share capital of Xstreamis by
  means of exchanging 439,137 shares of Tut common stock and $100,000 in cash on a
  pro-rata basis among the Shareholders for 16,843,253 shares of Xstreamis. Fully
  vested options to purchase 10,863 shares of Tut common stock under the Tut 1999
  Nonstatutory Option Plan were exchanged for fully vested options to purchase
  416,619 shares of Xstreamis on a pro-rata basis among the Xstreamis
  optionholders. The Xstreamis options were subsequently cancelled. At the
  Closing, ten percent of the shares issued pursuant to the Agreement were
  deposited into an escrow account (the "Escrow Fund") to secure the various
  indemnification and warranty obligations of certain of the Xstreamis former
  shareholders and affiliates (the "Warrantors"). Mr. Corbishley, in regards to
  his capacity as director, was one such affiliate. The Escrow fund is to be
  governed by the terms set forth in the Agreement. The Escrow Fund shall be the
  sole source of funds available for the fulfillment of any indemnification
  obligations of the Warrantors to Tut.
  
       The provisions of the Agreement described in this report are qualified in
  their entirety by reference to the actual text of that agreement, included as an
