Management Comments

Mr. Gary C. Evans, Chairman of the Company, commented, "In June 2005 Cimarex, Inc. (NYSE Amex: XEC) acquired the old Magnum Hunter Resources in a $2.2 billion dollar merger transaction. The Magnum Hunter name carried significant institutional recognition on Wall Street. After the sale of the company, I was able to secure the rights to use the name 'Magnum Hunter Resources' again and have now chosen Petro Resources Corporation as the corporate entity to use this brand. One of the issues I felt was very important when I joined the Company in late May 2009 as Chairman, was to cause the corporate name change to Magnum Hunter Resources. We had a tremendous 20 year run at the old Magnum Hunter in creating sequentially appreciating shareholder value. Further, we intend to bring similar disciplines we utilized so successfully at the old Magnum Hunter to the new Magnum Hunter. Specifically, these include a focus on operations and strategic property acquisition in known geologic regions of the oil patch. Low finding and development costs, reduced operating costs and low corporate overhead, are all necessary in an effort to generate superior returns to shareholders. The merger and acquisition market is showing a tremendous amount of deal flow, particularly in the distressed asset arena, and we remain very optimistic that the Company will have the opportunity to announce specific transactions related to these activities in the near future."
