Aqua Terra Water Management Hires Mark Harris to Serve as Chief Executive Officer

October 20, 2014

NEW YORK — Aqua Terra Water Management, L.P. (“Aqua Terra” or the “Company”) is pleased to announce that current board member Mark Harris has been hired to serve as the Chief Executive Officer of Aqua Terra. In addition to his new CEO responsibilities, Mr. Harris will continue to serve on the board of directors of the Company.

“Mark brings a wealth of experience and strong customer relationships with E&P companies that will help drive a corporate-level water management strategy,” said Scott Perekslis, Managing Partner and co-founder of New York-based private investment firm Bregal Partners, which formed Aqua Terra in November 2013. “Separately, we are also pleased to announce that Tom Johnston will augment his current role as President of the Company’s Canadian subsidiary by assuming the role of Chief Operating Officer for Aqua Terra. We believe Mark and Tom are ideally suited to help guide the Company’s further expansion into the U.S. market.”

Prior to joining Aqua Terra, Mark served as the President of Archer Wireline LLC (a wholly owned subsidiary of Archer Ltd.) and prior to Archer, as the Chief Executive of Gray Wireline. Mark has held executive management positions with Western Atlas, Wedge/Dialog, and Baker Hughes over his 30 year career.

Mr. Harris added, “Having worked with Scott Perekslis, Robert Bergmann [Managing Partner and co-founder of Bregal Partners] and Paul McGill [Principal at Bregal Partners] in various capacities at Gray Wireline, I am excited about the opportunity to partner again with members of the Bregal team.”

Mr. Harris continued, “Water management is a pervasive and growing need for North American oil and gas producers. As light oil and liquids production continues to increase in both U.S. and Canada, we believe the need for commercial water management will become more acute. As a cross-border provider of water management, we believe Aqua Terra is well situated to meet the needs of producers and the ever-increasing regulatory burdens associated with oilfield fluid management.”
