On April 21, 2018, the Registrant entered into an Agreement and Plan of Merger (the “Merger Agreement”) with CenterPoint Energy, Inc., a Texas corporation (“CenterPoint Energy”), and Pacer Merger Sub, Inc., an Indiana corporation and wholly owned subsidiary of CenterPoint Energy (“Merger Sub”), pursuant to which Merger Sub will merge with and into the Registrant (the “Merger”), with the Registrant continuing as the surviving corporation and becoming a wholly owned subsidiary of CenterPoint Energy.
