ITEM 5    OTHER MATTERS

On August 13, 1998, the Board of Directors of Plexus Corp., a Wisconsin
corporation, adopted a Shareholder Rights Plan. Under the Rights Plan, Plexus
shareholders of record as of August 27, 1998, (the "Rights Plan") will be 
granted a dividend of one preferred stock purchase right for each outstanding
share of Plexus common stock. Subject to the terms of the Rights Plan, each
Right entitles the registered holder to purchase one one-hundredth of a
share of Plexus' new series of preferred stock at an exercise price of $108.00.
Until Rights become exercisable, outstanding Plexus stock certificates will
represent both shares of Plexus common stock and Rights, (no separate
certificate will be issued for the Rights at this time). Rights will trade with
the shares of Plexus common stock until such time as they might become
exercisable.
