Prior to Teton, he served as Chief Operating Officer and a Director for Sefton Resources Inc. Between 1999 and 2001 he was a Non-Executive Director of Big Horn Resources, a Calgary-based oil and gas company. Ending in 1999, Mr. Arleth spent 22 years with Amoco and BP, holding various senior positions during his career including: Chair of the shareholder board of the Azerbaijan International Operating Company (AIOC) for BP-Amoco in Baku, Azerbaijan; President of Amoco Caspian Sea Petroleum Ltd. in Azerbaijan; Director of Strategic Planning for Amoco Corporations Worldwide Exploration and Production Sector in Chicago; and President of Amoco Poland Ltd. in Warsaw, Poland.

Mr. Arleth earned a Bachelor of Science degree in Geology from the University of California at Riverside and a Master of Science degree in Geology from San Diego State University. He has also completed the Executive Development Program at the Wharton School of the University of Pennsylvania.

Mr. Smith currently is sole practitioner of law at Mark R. Smith PC in Calgary, Alberta Canada and has been involved in the energy industry for over 20 years. He was previously a partner with Osler, Hoskin & Harcourt LLP for 1997 through June 2009 and was previously a partner with Burnet, Duckworth & Palmer LLP, where he articled in 1986. He was lead counsel in numerous corporate and asset acquisitions and divestitures, primarily in the energy industry. He was the Managing Director and CEO of Scimitar Hydrocarbons Inc.

"We are pleased to have attracted strong, independent Board representation for Sefton and its shareholders," said John J. Ellerton, Sefton's CEO and a director. "Mr. Arleth's extensive oil and gas industry experience and Mr. Smith's in-depth knowledge of securities law, mergers and acquisitions and oil and gas transactional law are two disparate skill sets that will lend important perspective and guidance to Sefton's Board. Their appointment to the Board greatly strengthens the Board. We welcome both new Board members and look forward to working with them in a collaborative manner."
