Explanation of Responses:

1. The reporting person became trustee of this trust on 2/3/93. The trust held Plexus shares prior to the reporting person becoming trustee. Therefore, there was no transaction in Plexus securities themselves.

2. Options granted under the Plexus Corp. 1995 Director's Stock Option Plan, or the 2005 Equity Incentive Plan, which qualify under Rule 16b-3. All fully vested.

3. Options granted under the Plexus Corp. 2006 Equity Incentive Plan; all vested immediately.
