Item 2.   Acquisition or Disposition of Assets.

On February 11, 1998, the Registrant completed the acquisition of Healthdyne 
Technologies, Inc., a Georgia corporation ("Healthdyne"). The acquisition of
Healthdyne was consummated pursuant to an Agreement and Plan of Reorganization
and related Agreement and Plan of Merger, each dated as of November 10, 1997, as
amended, pursuant to which RIGA, Inc., a wholly owned subsidiary of the
Registrant, was merged with and into Healthdyne (the "Merger"). Upon 
consummation of the Merger, approximately 11,900,000 shares of the Registrant's 
common stock became issuable to the former stockholders of Healthdyne, 
reflecting an exchange ratio of .9220 shares of the Registrant's common stock 
for each outstanding share of Healthdyne's common stock. In addition, 
approximately 1,300,000 additional shares of the Registrant's common stock are 
reserved for issuance upon exercise of options issued in replacement of
Healthdyne options that were not exercised prior to the consummation of the
Merger. The Merger was structured as a tax free reorganization and is intended
to be accounted for as a pooling of interests.
