*	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 stock unit award vested on January 1, 2018 and was settled for cash. Each share of phantom stock was the economic equivalent of one share of Vectren common stock.
(2)	The stock unit award was granted pursuant to the Vectren Corporation At Risk Compensation Plan (Plan) and was subject to the terms, provisions and conditions of the Plan and Plan grant agreement. The lifting of restrictions and forfeiture provisions were dependent upon continued service by the grantee until January 1, 2018, except as described in the Plan and the Plan grant agreement. The grantee was paid for each stock unit, in cash, the value of one share of Vectren's common stock on the date restrictions lapsed. The conditions associated with the award have been fulfilled and it has now been settled. This transaction was approved in accordance with Rule 16b-3.
