(1)  The Estimated Cash includes $2,250,000 in anticipated recovery from the
     sale of CellNet's royalty payments from BCN. The ownership of the
     royalty payments is disputed by Schlumberger RMS. A hearing has been set
     in October 2000 for the Bankruptcy Court to determine ownership. If it
     is determined that CellNet does not own the BCN royalty, then the
     Estimated Cash will be $2,250,000 lower.

(2)  CellNet has estimated the claim of Itron, Inc. at $0. There is currently a
     cash reserve of $1,050,000 set aside if Itron ultimately prevails in its
     litigation against CellNet. This reserve is included in the Estimated Cash.
     CellNet anticipates resolution of the Itron claim before December 31, 2000.
