      On March 8, 1996, Infrasonics, Inc. ("Infrasonics") entered into an 
Agreement and Plan of Merger (the "Merger Agreement") with Nellcor Puritan 
Bennett Incorporated ("NPB"), a Delaware corporation, whereby Infrasonics 
will be merged with and into NPB (the "Merger").  Subject to the terms and 
conditions of the Merger Agreement (including, without limitation, approval

based on the trading value of NPB's common stock so that the value of the 
consideration received by Infrasonics shareholders will not be less than 
$6.25 per share.

      A copy of the press release announcing the execution of the Agreement 
and Plan of Merger is attached as Exhibit 99.1 and is incorporated herein by
