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).
(1) The lifting of restrictions and forfeitability provisions were dependent upon performance during a measurement period from 1/1/08 through 12/31/10 and continued employment until 12/31/11. In the event of Retirement before the end of the Performance Period, the restrictions on the Stock Unit Awards shall be removed upon the expiration of the Performance Period and certification by the Compensation and Benefits Committee of the Company's performance. Mr. Ellerbrook retired as the CEO of the Company on May 31, 2010 and, due to retirement, received an estimated payout upon the vesting of the 2008 Stock Unit Award on December 31, 2010. The number of stock units Mr. Ellerbrook received is equal to the number of shares granted, as adjusted or forfeited based on the award's Performance Criteria, times the average of the closing price on the NYSE on the three consecutive trading days immediately preceding December 25., 2010. Upon the certification of the Performance results by the Committee in February 2011, Mr. Ellerbrook's payout will be reconciled to the extent that there is a variance between the amount paid at the end of 2010 and the final amount certified by the Committee. The Stock Unit Award was acquired pursuant to the Vectren Corporation At-Risk Compensation Plan and is subject to forfeiture as provided by the Plan.
(2) The stock unit award vesting in 2010 was settled for cash. Each share of phantom stock was the economic equivalent of one share of VVC common stock.
