earnings per share for the year 2004 as we enjoyed higher commodity prices and
we repurchased 3.9 million common shares during the year. Our production is
showing good growth, primarily through the drill bit, as fourth quarter
production was up 5% over the third quarter and 9% over the second quarter. We
begin 2005 with a strong balance sheet and a large prospect inventory. We
increased our drilling capital expenditures budget 24% over our 2004
expenditures and have multi-year development plans in the Bakken and Red River
plays in the Williston Basin, Northeast Mayfield in the Anadarko Basin and our
Hanging Woman coalbed methane play in the Powder River Basin."

This release contains forward looking statements within the meaning of
securities laws, including forecasts and projections for future periods. The
words "will," "believe," "anticipate," "intend," "estimate," "forecast," "plan"
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 2003 Annual
Report on Form 10-K filed with the SEC and the 2004 Annual Report on Form 10-K

                                      -2-



expected to be filed with the SEC on or about February 25, 2005. 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.

(1)           Discretionary cash flow is computed as net income plus
              depreciation, depletion, amortization, impairments, deferred
              taxes, exploration expense and non-cash changes related to the Net
              Profits Plan, less the cumulative effect of change in accounting
              principle and unrealized derivative gain/loss. See the attached
              financial highlights for a reconciliation of discretionary cash
              flow to net cash provided by operating activities, a presentation
              of other cash flow information, and a statement indicating why
              management believes the presentation of the non-GAAP measure of
              discretionary cash flow provides useful information to investors.

(1) Discretionary cash flow is computed as net income plus depreciation,
    depletion, amortization, impairments, deferred taxes, exploration expense,
    stock-based compensation expense, and changes in the net profits interest
    bonus plan liability less the change in accounting principle and unrealized
    derivative gain/loss. 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.
