Safe Harbor Statement and Reserves Disclaimer

This news release includes "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Act of 1934. A statement identified by the words "expects", "projects", "plans", and certain of the other foregoing statements may be deemed forward-looking statements. Although Gastar believes that the expectations reflected in such forward-looking statements are reasonable, these statements involve risks and uncertainties that may cause actual future activities and results to be materially different from those suggested or described in this news release. These include risks inherent in the drilling of natural gas and oil wells, including risks of fire, explosion, blowouts, pipe failure, casing collapse, unusual or unexpected formation pressures, environmental hazards, and other operating and production risks inherent in the natural gas and oil drilling and production activities, which may temporarily or permanently reduce production or cause initial production or test results to not be indicative of future well performance or delay the timing of sales or completion of drilling operations, risks with respect to natural gas and oil prices, a material decline in which could cause Gastar to delay or suspend planned drilling operations or reduce production levels, and risks relating to the availability of capital to fund drilling operations that can be adversely affected by adverse drilling results, production declines and declines in natural gas and oil prices and other risk factors described in Gastar's Annual Report on Form 10-K, as filed on March 27, 2007 with the SEC at www.sec.gov and on the System for Electronic Document Analysis and Retrieval (SEDAR) at www.sedar.com.

The SEC has generally permitted oil and gas companies, in their filings with the SEC, to disclose only proved reserves that, under SEC definitions and guidelines, a company has demonstrated by actual production or conclusive formation tests to be economically and legally producible under existing economic and operating conditions. This press release discloses "probable" reserves that the SEC's guidelines would prohibit us from including in our filings with the SEC. All of these volumes and estimates are by their nature more speculative than estimates of proved reserves under SEC definitions and guidelines and accordingly are subject to substantially greater risk of being actually realized.
