First quarter 2004 earnings were $21.4 million or $0.33 per diluted share. Revenues for the first quarter of 2005 were a record $143.8 million compared to $96.5 million for the first quarter of 2004. First quarter Discretionary Cash Flow(1) increased to a record $90.8 million in the first quarter of 2005 from $56.2 million in the first quarter of 2004. Daily oil and gas production during the first quarter 2005 averaged a record 229.4 million cubic feet of gas equivalent (MMCFE), up from 202.8 MMCFE in the comparable 2004 period. Average prices realized during the quarter were $6.22 per Mcf and $45.37 per barrel, 20% and 61% higher, respectively, than the realized prices in the first quarter of 2004. Mark Hellerstein, Chairman, President and CEO, commented, "This was another excellent quarter at St. Mary. We closed the Agate acquisition in January and had good drilling results. The addition of the previously announced Cromwell play to our other multi-year drilling programs gives us a solid base for future growth. We anticipate our drilling program will provide an increasing rate of production throughout the year."

The words "will," "believe," "anticipate," "intend," "estimate," "forecast" and "expect" and similar expressions are intended to identify forward looking statements. These statements involve known and unknown risks, which may cause St. Mary's actual results to differ materially from results expressed or implied by the forward looking statements. These risks include such factors as the uncertain nature of the expected benefits from the acquisition of oil and gas properties, the volatility and level of oil and natural gas prices, unexpected drilling conditions and results, the risks of various exploration strategies, production rates and reserve replacement, the imprecise nature of oil and gas reserve estimates, drilling and operating service availability, uncertainties in cash flow, the financial strength of hedge contract counterparties, the availability of economically attractive exploration and development and property acquisition opportunities and any necessary financing, competition, litigation, environmental matters, the potential impact of government regulations, and other such matters discussed in the "Risk Factors" section of St. Mary's 2004 Annual Report on Form 10-K filed with the SEC. Although St. Mary may from time to time voluntarily update its prior forward looking statements, it disclaims any commitment to do so except as required by securities laws.

The non-GAAP measure of discretionary cash flow is presented since management believes that it provides useful additional information to investors for analysis of St. Mary's ability to internally generate funds for exploration, development and acquisitions. In addition, discretionary cash flow is widely used by professional research analysts and others in the valuation, comparison and investment recommendations of companies in the oil and gas exploration and production industry, and many investors use the published research of industry research analysts in making investment decisions. Discretionary cash flow should not be considered in isolation or as a substitute for net income, income from operations, net cash provided by operating activities or other income, profitability, cash flow or liquidity measures prepared under GAAP. Since discretionary cash flow excludes some, but not all, items that affect net income and net cash provided by operating activities and may vary among companies, the discretionary cash flow amounts presented may not be comparable to similarly titled measures of other companies.
