                  ST. MARY REPORTS RECORD RESULTS FOR YEAR 2003

DENVER, February 26, 2004 - St. Mary Land & Exploration Company (NYSE: SM)
today reported record earnings of $95.6 million or $2.80 per diluted share for
the year ended December 31, 2003. Year 2002 earnings were $27.6 million or $0.97
per diluted share. Revenues for 2003 were $393.9 million compared to $196.4
million for 2002. St. Mary's discretionary cash flow(1) increased 95% from
$118.8 million in 2002 to $232.1 million in 2003.

Oil and gas production for 2003 was a record 76.9 billion cubic feet of gas
equivalent (BCFE), a 40% increase over 2002. The average realized price per MCFE
increased $1.38 to $4.75 in 2003, a 41% increase from the average price realized
in 2002. Estimated oil and gas reserves as of December 31, 2003 increased 21% to
594 BCFE from 491 BCFE at year-end 2002. Proved developed reserves are 89% of
total proved reserves.

Earnings for the fourth quarter were $24.7 million or $0.72 per diluted share
compared to $7.0 million or $0.24 per diluted share for the fourth quarter of
2002. Revenues for the fourth quarter of 2003 were $98.4 million compared to
$52.1 million for the same period in 2002. Discretionary cash flow(1) for the
fourth quarter increased 74% from the same period in 2002 to $63.0 million.
Average daily oil and gas production during the fourth quarter 2003 totaled
207.6 MMCFE, up 32% from 156.8 MMCFE in the comparable 2002 period. Average
prices realized during the quarter were $4.59 per Mcf and $26.85 per barrel,
which were 35% and 3% higher, respectively, than the realized prices in the
fourth quarter of 2002.

During the fourth quarter of 2003 the Company realized net proceeds totaling
$21.7 million and recognized pre-income tax gains totaling $7.5 million from the
sales of certain property interests in its Permian Basin and Rocky Mountain
regions.

Mark Hellerstein, Chairman, President and CEO, commented, "Our record earnings
reflect a 40% increase in production, high commodity prices, and moderate
increases in operating costs in 2003. We increased our estimated oil and gas
reserves 21%, while the proved undeveloped portion of our reserves decreased
from 12% to 11%. We replaced 293% of our production at an all-inclusive finding
cost of $1.05 per MCFE. Our balance sheet remains strong, and we enter 2004 on a
positive note. Our organic drilling budget is up 12% to $173 million over year
2003 expenditures, with significant continuing activity in Northeast Mayfield in

                                      -1-


Oklahoma and in the Bakken play in the Williston Basin, where we believe we have
significant running room into 2005 and possibly beyond. We have advanced the
Hanging Woman Basin coalbed methane project to the development stage and expect
production to begin next year. For the first time, we will be receiving 3-D
seismic data over our entire 25,000-acre fee lands in St. Mary Parish,
Louisiana. This was the legacy asset of the Company for decades that has
produced 200 million barrels of oil and 3.5 TCF of gas. Our interest is large
and additional development of the property has the potential to be very
significant."

The Company's previously announced forecast for the first quarter and the full
year of 2004 remains unchanged and is as follows:

                                        1st Quarter               Year

 Depreciation, depletion & amort. $1.05 - $1.10/MCFE     $1.10 - $1.20/MCFE

In 2004, St. Mary's weighted average shares outstanding will reflect 31,623,241
common shares outstanding at December 31, 2003 less the Company's repurchase of
3,380,818 of those shares on February 9, 2004 from Flying J Oil & Gas Inc.
and Big West Oil & Gas Inc., as previously announced in the Company's
February 9, 2004 press release. If there are no significant share issuances
during the remainder of 2004, on a weighted average basis the first quarter of
2004 will reflect approximately 1,900,000 less shares outstanding and the year
2004 will reflect approximately 3,100,000 less shares outstanding as compared to
year-end 2003. The attached financial highlights include a table showing the
impact of this transaction to our balance sheet on a pro-forma basis as of
December 31, 2003.

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" and

statements. These statements involve known and unknown risks, which may cause
St. Mary's actual results to differ materially from results expressed or implied

                                      -2-


by the forward looking statements. These risks include such factors as the
volatility and level of oil and natural gas prices, unexpected drilling
conditions and results, production rates and reserve replacement, reserve
estimates, drilling and operating service availability and uncertainties in cash
flow, the financial strength of hedge contract counterparties, the availability
of attractive exploration and development and property acquisition opportunities
and any necessary financing, expected acquisition benefits, competition,
litigation, environmental matters, the potential impact of government
regulations, and other such matters discussed in the "Risk Factors" section of
St. Mary's 2002 Annual Report on Form 10-K filed with the SEC and the 2003
Annual Report on Form 10-K expected to be filed with the SEC on or about
February 27, 2004. 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 mark-to-market adjustments
              related to compensation plans, less the cumulative effect of
              change in accounting principle and unrealized derivative gain. 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,
    and non-cash mark-to-market adjustments related to compensation plans less
    the change in accounting principle and unrealized derivative 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.




PRO FORMA BALANCE SHEET IMPACT OF FLYING J SHARE REPURCHASE
- -----------------------------------------------------------
(In thousands, except per share amounts)

    On February 9, 2004, the Company repurchased from Flying J 3,380,818
    restricted shares of common stock for a total of $91.0 million. These shares
    were originally issued by St. Mary to Flying J on January 29, 2003, in
    connection with St. Mary's acquisition of oil and gas properties. In
    addition to issuing the shares in the acquisition, St. Mary loaned Flying J
    $71.6 million. Flying J used the proceeds to repay their outstanding loan
    balance of $71.6 million. Accrued interest, which has not been recorded by
    the Company for financial reporting purposes due to the non-recourse nature
    of the loan, was forgiven. The net $19.4 million cash outlay was funded from
    the Company's existing cash balances and borrowings under its bank credit
    facility.

    The following table shows the unaudited pro forma effects on the summarized
    consolidated balance sheet had the transaction occurred on December 31,
    2003. The table assumes that the Company would have borrowed the necessary
    cash payment from its existing credit facility.
