ITEM 2.        ACQUISITION OR DISPOSITION OF ASSETS.

               On March 5, 1999, Plastron Industries, Inc., a newly formed
               Delaware corporation and wholly-owned subsidiary of the
               Registrant ("Buyer"), consummated its purchase of substantially
               all of the assets of Plastron Industries L.P., a Delaware limited
               partnership ("Plastron"), pursuant to the terms of that certain
               Asset Purchase Agreement dated February 17, 1999 (the "Purchase
               Agreement") among Buyer, the Registrant, Plastron and the general
               partner of Plastron, Plastron Management, Inc., an Illinois
               corporation ("PMI").

               The aggregate purchase price paid for Plastron consisted of (i)
               $20.0 million in cash, (ii) a four-year warrant exercisable to
               purchase up to 200,000 shares of the Registrant's common stock at
               $11.75 per share, and (iii) the assumption of certain
               liabilities, principally trade payables and accrued obligations
               of approximately $1.0 million (net of the estimated effect of a
               one time purchase price adjustment to be calculated comparing
               Plastron working capital at closing to $1.85 million). The
               aggregate purchase price was determined through negotiations
               between the Registrant and PMI.

               The Registrant also agreed to grant to certain management
               employees of Plastron (i) the right to purchase, within thirty
               days following consummation of the acquisition (and subject to
               the prior filing of the Plastron audited financial statements
               required by Item 7 of this current report), up to a maximum of
               200,000 restricted shares of the Registrant's common stock at a
               recent market price, and (ii) an equal number of non-statutory
               stock options to acquire the Registrant's common stock at the
               same recent market price, with such options to vest based on the
               percentage obtained by dividing the net income of Buyer after
               closing by $3.0 million, or fully in nine years. Additionally,
               12,000 similarly priced non-statutory stock options will be
               granted to consultants of Plastron.

               Plastron is a leading manufacturer of precision thermoplastic
               parts for wound electronic components such as transformers,
               relays and coils, known in the industry as coil forms or
               "bobbins." Plastron's assets consist primarily of real property,
               plant and equipment, molds, trade accounts receivable and
               inventory. All of the acquired assets, which are located in
               Bensenville, Illinois, will be used in the on-going operations of
               Buyer in a manner consistent with their prior use.

               The funds used for the cash portion of the purchase price were
               borrowed from the Registrant's primary lender, Comerica
               Bank-California, a California banking corporation ("Lender"),
               pursuant to an Amended and Restated Loan Agreement dated March 5,
               1999 (the "Loan Agreement"). Lender agreed to act as the agent
               under the Loan Agreement for the various financial institutions
               that may become parties thereto.

               EXHIBITS.

               (a)    Financial Statements of Businesses Acquired.
