Tri-Valley Names New VP of Exploration

Tri-Valley announced the appointment of Michael P. Stark, 61, as Vice President of Exploration, a position that had been vacant at the Company since 2008. Mr. Stark will have overall responsibility for the Company’s exploration activities, including land management, and will join the executive management team reporting directly to Maston Cunningham, the Company’s Chief Executive Officer. The appointment is effective immediately.

Mr. Stark has over 35 years of experience with leading oil and gas producers in increasingly responsible positions. He was most recently Vice President of Exploration and Land for Ivanhoe Energy (USA) Inc., where he worked for 12 years. Prior to Ivanhoe, Mr. Stark spent 20 years at Occidental Oil and Gas Corporation (Oxy). After leaving Oxy in 1998, Mr. Stark co-founded Diatom Petroleum, a startup exploration company, which was acquired by Ivanhoe Energy in 2000. He began his career as a geologist with Texaco Incorporated.

"Mike is a strong addition to our management team, bringing a wealth of experience in oil and gas exploration both in California and abroad," said Mr. Cunningham. "Mike will help Tri-Valley establish an exploration strategy that will complement our current production and development efforts, and also leverage existing leads and prospects generated from our California data library that includes over 25,000 miles of vintage seismic. He will play a significant role in the Company's future growth as we continue to focus on maximizing the potential of our existing properties while seeking other projects that are appropriate for Tri-Valley," added Mr. Cunningham. "Mike's hiring is quite timely given the renewed interest in California exploration following Oxy’s large discovery in Kern County last year, and by its recent disclosure that gross potential reserves in the area of its discovery may total 500 million barrels of oil equivalents by the end of 2010."

Mr. Stark has a B.S. in Geology from the University of California at Los Angeles and a M.S. in Geology from Iowa State University.
