Discretionary cash flow increased to $193.2 million for the third quarter of 2008 from $158.9 million in the same period of the preceding year. Net cash provided by operating activities increased to $252.0 million for the third quarter of 2008 from $191.7 million in the same period in 2007. The increase year over year for both of these metrics is primarily attributable to higher price realizations on oil and natural gas sales during the third quarter of 2008.

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.

Production for the third quarter of 2008 was negatively affected by production disruptions caused by Hurricanes Gustav and Ike. Additionally, the Company did not have the production benefit in the third quarter of 2008 of non-strategic properties that were divested in January of 2008. Below is a summary table comparing production for the third quarters of 2008 and 2007.

St. Mary's reported production came in slightly below the guidance range of 28.0 to 29.0 BCFE, although the Company estimates it would have been at the mid-point of guidance if not for the impact of the hurricanes. The Company's oil and gas production growth on retained properties year over year is being driven by development of the Cotton Valley and James Lime programs in the ArkLaTex region, drilling in the horizontal Woodford shale program in eastern Oklahoma, drilling in the Wolfberry tight oil program in West Texas, successful offshore activities in the Gulf Coast region, and the acquisition and subsequent development of Olmos shallow gas assets in South Texas.

As mentioned above, the Company's production was disrupted during the quarter by Hurricanes Gustav and Ike. The former impacted production primarily in South Louisiana, including St. Mary's fee properties in St. Mary Parish, by damaging electrical infrastructure in the area. The latter storm impacted properties in the central Gulf of Mexico, including the Galveston Bay area. Additionally, some gas plants that process Company gas production in the Permian Basin were restricted due to damage to electrical infrastructure and fractionation facilities along the Gulf Coast. These limitations caused St. Mary to shut-in a portion of its Permian Basin production. Production in the Permian has been restored, and the Company and its operating partners are currently working to restore production in the greater Gulf Coast and Gulf of Mexico. Currently, the Company estimates that roughly five percent of its pre-hurricane production is still shut-in. Several St. Mary properties were impacted by Hurricane Ike, which struck the Texas Gulf Coast late in the third quarter of 2008. The Company's operated platform at Vermilion 281 was toppled and lost during the storm and production facilities at Goat Island in Galveston Bay were destroyed. Reserves and production associated with these properties were not material to the financial position of the Company. Net of insurance proceeds that are expected to be received, the Company recognized a loss of $7.0 million related to the remediation and repair work, which is included in the line Other Expense in the consolidated statement of operations included at the end of this release.

Revenues for the quarter were $324.1 million compared to $246.7 million for the same period in 2007. Average prices, excluding hedging activities, were $9.96 per Mcf and $111.97 per barrel during the quarter. These prices were 67% and 56% higher, respectively, than the third quarter of 2007. Average realized prices, inclusive of hedging activities, were $9.51 per Mcf and $83.30 per barrel in the third quarter of 2008, which is an increase of 35% and 23%, respectively, from the same period a year ago. In the third quarter of 2008, the Company's average equivalent price per MCFE, net of hedging, was $11.01 per MCFE, which is an increase of 27% from the $8.69 per MCFE realized in the comparable period in 2007.

Lease operating expense increased 17% or $0.23 per MCFE between the third quarters of 2007 and 2008 to $1.57 per MCFE. This amount is slightly above the Company's lease operating expense guidance, however it should be noted that as a result of the hurricane disruptions there were fewer MCFE of production to cover fixed operating costs. Recurring lease operating costs were up approximately 15% or $0.18 per MCFE year over year. The increase in this expense is a result of stronger commodity prices and high levels of activity over the last twelve months. Services that utilize fuel have seen meaningful increases in cost, and vendors have raised prices in this environment where oilfield supplies and services are limited in availability. Workover expense increased by approximately $1.6 million year over year, due to major workovers performed on two wells at Constitution Field offset by less workover activity in the Rocky Mountain region.

Transportation expense doubled in the third quarter of 2008 to $0.24 per MCFE from $0.12 per MCFE a year ago. The increase is being driven primarily by the change in asset composition, and the associated transportation arrangements, in the Gulf Coast and ArkLaTex regions. The acquisition and subsequent development of onshore properties in South Texas in the second half of 2007 significantly changed the asset mix in the Gulf Coast toward properties that have higher pricing at the well head and which also have higher per unit transportation costs. Transportation costs have also increased in the ArkLaTex region for similar reasons as the Company has developed assets in areas with different transportation arrangements than existed in areas where St. Mary has historically operated.

Significant commodity price increases for both oil and natural gas resulted in a 50% increase in production taxes between the third quarters of 2008 and 2007. Production taxes for the third quarter were $0.81 per MCFE, which was below guidance as a result of lower than forecasted commodity prices throughout the quarter.

General and administrative expense for the third quarter of 2008 was $0.87 per MCFE, representing a 50% increase from the $0.58 per MCFE recognized in the comparable quarter a year ago. The significant increase year over year is due primarily to compensation-related costs associated with increased headcount. Costs associated with headcount, such as salary and accrued bonus, benefits, and office space, have continued to push general and administrative costs higher. Increases in commodity prices between the periods also led to larger cash payments to participants in the Net Profits Plan. Results for the third quarter of 2008 were above guidance on a per MCFE basis. Part of this is attributable to lower than forecasted production volumes to cover the largely fixed portion of the Company's general and administrative cost base. Additionally, certain general and administrative costs are tied to the Company's profitability, which was better than initially forecasted when guidance was provided.

Depletion and depreciation expense increased to $2.61 per MCFE in the third quarter of 2008 from $2.15 per MCFE in the comparable period in 2007. Depletion and depreciation expense reflects the higher finding cost environment experienced by St.Mary and others in the industry in recent years. Depletion and depreciation expense was lower than guidance in part because of shut-in production related to the hurricanes late in the quarter. The depletion pools in the Gulf Coast generally have higher DD&A rates per MCFE due to the higher finding costs associated with high production rate, short-lived wells. These depletion pools also have higher DD&A rates than the Company's average DD&A rate. As a result, the curtailment of production in the Gulf Coast lowered the depreciation and depletion rate for the quarter.

St. Mary recognized $6.7 million in bad debt expense before income taxes in the third quarter of 2008 as a result of the bankruptcy of SemGroup L.P. which occurred in July of 2008. Including bad debt expense recorded last quarter, the Company has established an allowance of $16.6 million for the amounts owed by this purchaser. No further amounts are anticipated to be reserved going forward for SemGroup L.P., and the Company continues to pursue collection of the amounts owed.

The third quarter of 2008 saw St. Mary recognize a pre-tax non-cash benefit of $34.9 million as a result of the decrease in the Net Profits Plan liability. The Net Profits Plan liability decreased during the quarter as a result of the significant decrease in forecasted oil and natural gas prices from June 30, 2008 to September 30, 2008. 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.

FINANCIAL POSITION AND LIQUIDITY

As of September 30, 2008, St. Mary had total long-term debt of $457.5 million, comprised of $287.5 million in 3.50% Senior Convertible Notes and $170.0 million drawn under our existing long-term credit facility. The Company's debt-to-book capitalization ratio was 31% as of the end of the quarter. The long-term credit facility requires compliance with two financial covenants; a leverage to trailing EBITDA limit and a minimum modified current ratio multiple. St. Mary was comfortably in compliance with both covenants at quarter end.

The borrowing base for the long-term credit facility was redetermined by St. Mary's bank group on October 1, 2008, at an amount of $1.4 billion. The bank group is comprised of 11 banks, led by Wachovia and Wells Fargo. St. Mary has experienced no issues utilizing the credit facility. The Company has elected a commitment amount of $500 million at this time given its expected near term liquidity needs.

   (2) The (gain) loss on insurance settlement is included within line
   item other revenue on the consolidated statements of operations.
   (3) The loss related to hurricanes is included within line item
   other expense on the consolidated statements of operations.
   (4) Adjusted net income is calculated as net income adjusted for
   significant non-cash and non-recurring items. Examples of non-cash
   charges include changes in the Net Profits Plan liability, unusual
   and non-recurring bad debt expense, and unrealized derivative gains
   and losses. Examples of non-recurring items include gains and losses
   from sales of proved properties, gains and losses on insurance
   settlements, and losses 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.

   (5) Discretionary cash flow is computed as net income adjusted for
   (gain) loss on insurance settlement, (gain) loss on sale of proved
   properties, depreciation, depletion, amortization, asset retirement
   obligation liability accretion, impairments, deferred taxes,
   exploration (benefit) expense, stock-based compensation expense,
   change in Net Profits Plan liability, loss related to hurricanes,
   and the effect of 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. See the Consolidated Statements of Cash Flows herein for
   more detailed cash flow information.
