ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

         On June 27, 1996, the Registrant completed the acquisition of
Infrasonics, Inc., a California corporation ("Infrasonics").  The acquisition
of Infrasonics was consummated pursuant to an Amended and Restated Agreement
and Plan of Merger, dated as of May 14, 1996, pursuant to which Infrasonics was
merged with and into Registrant (the "Merger").  In the Merger, approximately
1,282,683 shares (2,565,367 post-split) of the Registrant's common stock (not
including 67,097 shares (134,193 post-split) issuable under outstanding
options) were issued to the former stockholders of Infrasonics, reflecting an
exchange ratio of .120 of one share of the Registrant's common stock for each
outstanding share of Infrasonics' common stock.  The Merger was structured as a
tax free reorganization and is intended to be accounted for as a pooling of
interests.

         A press release regarding the acquisition is attached hereto as
Exhibit 20.1 and incorporated herein by reference.
