DENVER, August 3, 2009 – St. Mary Land & Exploration Company (NYSE: SM) today reports financial results from the second quarter of 2009.

MANAGEMENT COMMENTARY

Tony Best, CEO and President, remarked, “St. Mary had a strong second quarter. We beat our production targets and performed well against our cost guidance. The Company successfully tested the Eagle Ford shale on its high working interest acreage in South Texas and continued to advance its other resource plays. We continue to execute well on the business plan that we set out at the beginning of the year.”

SECOND QUARTER 2009 RESULTS

St. Mary posted a net loss for the second quarter of 2009 of ($8.3 million), a loss of ($0.13) per diluted share. This compares to net income of $32.5 million, or $0.52 per diluted share, for the same period in 2008. Adjusted net income for the quarter, which adjusts for significant non-recurring or unusual non-cash items, was $15.2 million, or $0.24 per diluted share, versus $80.5 million, or $1.28 per diluted share, for the second quarter of 2008. A summary of the adjustments made to arrive at adjusted net income (loss) is presented in the table below.

* On January 1, 2009, the Company adopted FASB Staff Position APB 14-1, "Accounting for Convertible Debt Instruments That May Be Settled in Cash Upon Conversion (Including Partial Cash Settlement)." This accounting pronouncement requires that its provisions be adopted retrospectively. Accordingly, the consolidated financial statements for presented prior periods have been restated to conform with this new accounting standard.

Discretionary cash flow decreased to $117.7 million for the second quarter of 2009 from $222.4 million in the same period last year. Net cash provided by operating activities decreased to $116.6 million for the second quarter of 2009 from $173.8 million in the same period in 2008. A major driver of the decrease year over year in each of these metrics was the significant decrease in oil and natural gas prices between those periods which is described in more detail below.

Adjusted net income and discretionary cash flow are non-GAAP financial measures – please refer to the respective reconciliation in the accompanying Financial Highlights section at the end of this release.

St. Mary reported quarterly production of 28.2 BCFE for the second quarter of 2009, which was above the guidance range of 26.5 to 28.0 BCFE. The primary driver for this outperformance was better than projected results from the Company’s drilling program. Production for the same period last year was 28.6 BCFE, which included 1.3 BCFE of production from assets that were later disposed of in 2008. Sequentially, production in the second quarter of 2009 was essentially flat with the preceding quarter.

Revenues for the quarter were $205.2 million compared to $356.9 million for the same period in 2008. In the second quarter of 2009, the Company’s average equivalent price per MCFE, net of hedging, was $6.68 per MCFE, which is a decrease of 42% from the $11.61 per MCFE realized in the comparable period in 2008. Average realized prices, excluding hedging activities, were $3.07 per Mcf of natural gas and $53.96 per barrel of oil during the quarter. These prices were 72% and 55% lower, respectively, than those in the second quarter of 2008. Average realized prices, inclusive of hedging activities, were $5.19 per Mcf of natural gas and $56.72 per barrel of oil in the second quarter of 2009, which is a decrease of 48% and 36%, respectively, from the same period a year ago.

Lease operating expense of $1.26 per MCFE in the second quarter of 2009 was below the Company’s guidance of $1.49 to $1.54 per MCFE. This represents a 12% decrease from the $1.43 per MCFE in the comparable period last year. Sequentially, lease operating expense declined 13% or $0.19 per MCFE in the second quarter of 2009 from the first quarter. The Company is experiencing decreases in operating costs across most of its operating areas as a result of lower levels of activity in the industry as well as the broader economy.

Transportation expense of $0.16 per MCFE in the second quarter of 2009 was below guidance of $0.19 to $0.24 per MCFE. The reported per unit expense was a decrease from $0.20 per MCFE for the comparative period in 2008. Transportation expense was also down $0.03 per MCFE from the first quarter of 2009.

Significant commodity price decreases over the past year for both oil and natural gas resulted in year over year declines in production taxes, both on a per MCFE basis and in absolute dollars. Between the second quarters of 2009 and 2008, production taxes on a per MCFE basis decreased 65% from $0.95 to $0.33. Production taxes increased sequentially from $0.32 per MCFE in the first quarter to $0.33 per MCFE in the second quarter of 2009. The Company’s results for the second quarter were within the guidance range of $0.28 to $0.33 per MCFE provided for the quarter.

Total general and administrative expense for the second quarter of 2009 was $0.64 per MCFE, representing a 17% decrease from the $0.77 per MCFE recognized in the comparable quarter a year ago. The guidance range for total G&A expense for the quarter was $0.71 to $0.78 per MCFE. The decrease year over year relates primarily to smaller payments to participants in the legacy Net Profits Plan, which was affected by lower commodity prices realized in the second quarter of 2009. Offsetting a portion of these decreases were increases between the periods in costs associated with higher headcount, such as salary and office space, related to personnel additions made throughout 2008.

Depletion and depreciation expense decreased to $2.49 per MCFE in the second quarter of 2009, which was well below the Company’s guidance range of $2.90 to $3.10 per MCFE. DD&A in the comparable period of 2008 was $2.67 per MCFE.

Sequentially, DD&A decreased 23% from $3.23 per MCFE in the first quarter of 2009. The decrease in DD&A in the second quarter is largely a function of the Company’s decision to market for sale certain non-strategic natural gas properties. These properties have a higher per unit DD&A than the Company’s average DD&A per MCFE. Accounting rules do not permit assets held for sale to be depleted, and as a result the entity-wide DD&A per MCFE rate went down. Additionally, property impairments recognized in prior quarters have meaningfully lowered the cost basis of the Company’s properties, which also puts downward pressure on DD&A.

St. Mary recognized $6.0 million before income taxes in non-cash impairments for proved properties in the second quarter of 2009. The majority of the proved property impairments related to offshore Gulf platforms in which St. Mary is relinquishing its ownership interests. The Company also recognized $11.6 million for unproved properties in the second quarter of 2009, compared to $2.1 million in the same period in 2008. The largest portion of the unproved property impairments in the current year related to Floyd Shale acreage located in Mississippi. The Company also recognized an impairment of materials inventory for $2.7 million related to the write-down of tubular goods purchased in 2008 to current market value.

Exploration expense of $19.5 million was recognized in the second quarter of 2009, compared to $17.4 million in the same period in 2008. The increase year over year reflects higher levels of geological and geophysical spending.

In the second quarter of 2009, St. Mary recognized a pre-tax non-cash expense of $2.4 million as a result of the increase in the Net Profits Plan liability, compared to $68.1 million in the second quarter of 2008. This periodic expense is a reflection of change in the liability during the respective periods. This liability is a significant management estimate and is highly sensitive to a number of assumptions including future commodity prices, production rates, and operating costs. The last pool created under this legacy compensation plan was in 2007.

FINANCIAL POSITION AND LIQUIDITY

As of June 30, 2009, St. Mary had total long-term debt of $537.7 million, comprised of $275.0 million drawn under its existing long-term credit facility and $262.7 million in 3.50% Senior Convertible Notes, net of debt discount. The credit facility matures in July of 2012 and the Senior Convertible Notes cannot be put to the Company’s until April of 2012. The Company’s debt-to-book capitalization ratio was 35% as of the end of the quarter.

As of July 28, 2009, St. Mary had $255.0 million drawn on the revolver and had $421.7 million in unused borrowing capacity. The Company’s next regularly scheduled borrowing base redetermination is scheduled for October of this year.

(1) The loss related to hurricanes is included within line item other expense on the consolidated statements of operations.

(2) Adjusted net income is calculated as net income (loss) adjusted for significant non-cash and non-recurring items. Non-cash charges and adjustments include
change in the Net Profits Plan liability, unrealized derivative (gain) loss, impairment of proved properties, abandonment and impairment of unproved properties, and
impairment of materials inventory. Non-recurring items include gain on sale of proved properties, and loss related to hurricanes. The non-GAAP measure of
adjusted net income is presented because management believes it provides useful additional information to investors for analysis of St. Mary’s fundamental
business on a recurring basis. In addition, management believes that adjusted net income 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. Adjusted net income should not be considered in isolation or as a substitute for
net income, income from operations, cash provided by operating activities or other income, profitability, cash flow, or liquidity measures prepared under GAAP.
Since adjusted net income excludes some, but not all, items that affect net income and may vary among companies, the adjusted net income amounts presented
may not be comparable to similarly titled measures of other companies.

(3) Discretionary cash flow is computed as net income (loss) adjusted for gain on sale of proved properties, loss related to hurricanes, depletion,
depreciation, amortization, and asset retirement obligation liability accretion, exploration, impairment of proved properties, abandonment and impairment of
unproved properties, unrealized derivative loss (gain), change in Net Profits Plan liability, stock-based compensation expense, amortization of debt discount,
impairment of materials inventory, and deferred income taxes. 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. See the consolidated
statements of cash flows herein for more detailed cash flow information.
