(1) This disposition represents the performance adjustment forfeiture relating to the January 1, 2003 grant under the Vectren Corporation At Risk Compensation Plan. This grant is exempt under Section 16b-3 and was previiously approved by the board of directors. This grant is subject to forfeiture as provided under the Plan.
(3) The common stock was acquired pursuant to the Vectren Corporation At Risk Compensation Plan and is subject to forfeiture as provided by the plan and the plan agreement. The lifting of restrictions and the forfeitability provisions are dependent upon performance during a measuring period from January 1, 2006 through December 31, 2008 and continued employment until December 31, 2009. The board of directors approved the acquisition in accordance with Rule 16b-3(d).
