Scott Zimmerman, President and CEO, said: "Our management and Board changes mark our transition from a development stage company to that of an exploration and production company with quality projects, growing production and further potential over its leasehold. By installing an experienced oil and gas management team, we can accomplish the next step in the South Texas Oil Company’s growth initiative, to focus on best exploiting our assets to enhance shareholder value. The assembled team, including Jim Grubb, our Vice President of Geology, has worked together in the past and, importantly, has extensive G&G experience in the basins in which we operate. We are fortunate to have a portfolio of low-to-medium-risk oil focused projects that we control." Mr. Zimmerman continued, "I personally am excited to be leading South Texas Oil, working in tandem with Mike Pawelek and the Board, as we move to the next phase of what we believe will feature growth in reserves and production from each of our core assets. On behalf of the Board of Directors, I would like to thank Murray for his vision, dedication and service to the Company, which has allowed us to take this next step.” Commenting on the changes, Mr. Conradie said: "As an entrepreneur and founder of companies, I recognize that the Company has reached the stage to be turned over to a seasoned, technically oriented oil and gas management team with experience in further growing exploration and production companies in order to continue building shareholder value. Scott and his team will best be able to capitalize on the properties that were assembled and, thanks to the Company’s strong financial position, will have the flexibility to acquire and exploit additional assets as well. For me personally, the time is right for a transfer of leadership and I look forward to supporting Scott as he takes on his new responsibilities.” About South Texas Oil Company Austin-based South Texas Oil Company acquires, explores and exploits predominantly oil-bearing formations in its core operating areas in south-central and southwest Texas and in the DJ Basin of northeast Colorado.
