Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(2)	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).
(4)	The reporting person had deferred the value of restricted stock vesting in 2005 in the Vectren Corporation Non-Qualified Deferred Compensation Plan resulting in the acquisition of phantom shares.
(5)	Phantom stock units held under the non-qualified deferred compensation plan will effectively be exercised at the time the amounts represented by these units are paid out under the Plan. Generally, unless provided otherwise by the participant, the payout begins with the end of the officer's employment with the Company or one of its participating subsidiaries. Pursuant to the non-qualified deferred compensation plan, payouts can occur for up to 15 years. Amounts held in the phantom stock accounts would be amortized over that period unless directed otherwise by the participant.
(1)	The reporting person had deferred the value of restricted stock vesting in 2005 to the Vectren Corporation Non-Qualified Deferred Compensation Plan, resulting in the disposition of shares of restricted stock previously reported as beneficially owned.
