  Item 2.  Acquisition or Disposition of Assets
  
           On July 25, 1996, Osmonics, Inc. ("Osmonics") completed the
           previously announced acquisition of Desalination Systems, Inc.
           ("DSI").  The shareholders of DSI approved an Agreement and
           Plan of Merger dated May 17, 1996 (the "Merger Agreement"),
           among DSI, Osmonics, and a subsidiary of Osmonics (the
           "Subsidiary"), pursuant to which the Subsidiary was merged with
           and into DSI.  Under the Merger Agreement the outstanding
           shares of DSI Common Stock were converted, in a tax-free
           reorganization, into shares of Osmonics Common Stock.  Each
           share of Class A Common Stock of DSI, no par value per share
           (the "DSI Class A Common Share"), issued and outstanding
           immediately prior to the merger was exchanged for approximately
           144.070 shares of Common Stock of Osmonics, par value $0.01 per
           share (the "Osmonics Common Shares"), and each share of Class B
           Common Stock of DSI, no par value per share (the "DSI Class B
           Common Share"), issued and outstanding immediately prior to the
           merger was exchanged for approximately 157.107 shares of the
           Osmonics Common Shares.  Osmonics issued an aggregate of
           1,312,827 shares (maximum number of shares issuable as a result
           of the acquisition; actual number of shares issued may be less
           due to fractional shares) of Osmonics Common Stock to the
           former DSI shareholders.  As a result of the merger, DSI
           shareholders are shareholders of Osmonics and DSI is a wholly-
           owned subsidiary of Osmonics.  
  
           DSI's primary business is the manufacture of membranes used for
           reverse osmosis, nanofiltration, ultrafiltration and
           microfiltration.  These membranes are made into spiral
           elements.  Osmonics intends to continue the business of DSI.
