      enterprise. | 
| ·        | Broad Economic Downturn and
      Impacts on Capital Markets and Commodity Prices.  During
      2008 the global economy experienced a significant downturn.  The
      crisis began over concerns related to the U.S. financial system and
      quickly grew to impact a wide range of industries.  There were
      two significant ramifications to the exploration and production industry
      as the economy continued to deteriorate.  The first was that
      capital markets essentially froze.  Equity, debt, and credit
      markets shut down.  We were able to weather this initial shock
      as a result of our strong liquidity position and relatively limited
      capital commitments.  The second impact to the industry was that
      fear of global recession resulted in a significant decline in oil and gas
      prices.  We have been able to cope with the downturn in prices
      as a result of our ability to quickly scale down our activity and keep our
      capital investments within cash flow.  Our existing commodity
      hedge position provided a further backstop as commodity prices continued
      to decline.  We believe the environment in 2009 will continue to
      be challenging with respect to financing and commodity
      pricing. | 
| ·       | Significant Volatility in
      Commodity Prices.  As mentioned above, 2008 saw the
      exploration and production sector impacted by significant volatility in
      the prices for crude oil and natural gas.  Our operations and
      financial condition are significantly impacted by these
      prices.  Our crude oil is sold on contracts that pay us the
      average of posted prices for the period in which the crude oil is
      sold.  The spot price for NYMEX crude oil in 2008 ranged from a
      high of $145.29 per barrel in early July to a low of $31.41 per barrel in
      late December.  The average spot price for oil during the year
      was $99.92 per barrel.  The volatility in oil prices during the
      year was a result of geopolitical unrest in various producing regions
      overseas as well as domestic
      concerns about refinery utilization and petroleum product inventories
      pushing prices up during the first half of the year.  Global
      demand destruction drove prices down as the economy weakened in the second
      half of 2008. | 
|  | We sell the majority of our natural gas on contracts that are based
      on first of the month (also frequently referred to as bid week) index
      pricing.  The Inside FERC bid week price for Henry Hub, a widely used
      industry measuring point, averaged $9.04 per MMBtu in 2008, with a high of
      $13.11 per MMBtu in July and a low of $6.47 per MMBtu in
      November.  Natural gas prices came under pressure in the second
      half of the year as a result of lower domestic product demand that was
      caused by the weakening economy and concerns over excess supply of natural
      gas due to high levels of drilling activity.  Some of the
      regional markets where we sell gas have seen increased downward pressures
      on price as a result of high levels of activity in the region and either a
      lack of pipeline takeaway capacity or local demand.  This has
      been most pronounced in our Mid-Continent and Rocky Mountain
      regions. | 
| ·       | Decrease in Year-End
      Reserves.  Due in large part to the price declines in the
      second half of 2008 described above, proved reserves decreased 20 percent
      to 865.5 BCFE at December 31, 2008, from 1,086.5 BCFE at
      December 31, 2007.  We added 170.1 BCFE from our drilling
      program and 29.1 BCFE from acquisitions during the year.  During
      the year, 61.4 BCFE were sold in divestitures, primarily in the Rocky
      Mountain and Mid-Continent regions.  We had a negative revision
      of 244.2 BCFE that consisted of 44.5 BCFE in downward performance
      revisions and a downward pricing revision of 199.7 BCFE due primarily to
      meaningfully lower commodity prices at the end of 2008.  The
      prices used for the 2008 year-end reserves decreased significantly from a
      year earlier.  Oil prices declined 54 percent from $95.98 per
      barrel to $44.60 per barrel while natural gas prices dropped 16 percent
      from $6.80 per MMBtu to $5.71 per MMBtu.  Over half of the
      pricing revisions occurred in the oil-weighted Rocky Mountain region,
      which saw its proved reserves adversely impacted by low prices and wider
      differentials at the end of 2008.  We also saw meaningful price
      and performance revisions in the Gulf Coast region related primarily to
      our Olmos shallow gas properties in South Texas.  A large
      decline in the natural gas liquid fractionation spread year over year
      resulted in a significantly lower price for natural gas in the
      determination of proved reserves for the region at
      year-end.  The performance revision is due to poorer reservoir
      performance then we initially expected.  The reservoir is more
      compartmentalized then originally assumed and we have seen lower reserve
      outcomes while attempting to infill parts of the
  field. | 
| ·      
       |  Impairment of Proved
      Properties.  The low prices at year-end for oil and gas
      and the decrease in proved reserves described above both contributed to a
      pre-tax non-cash impairment of proved properties in the amount of $302.2
      million in 2008.  There was no impairment of proved properties
      in 2007.  Approximately $154.0 million of the 2008 impairment
      was related to assets in South Texas that were acquired in
      2007.  We also saw an impairment associated with proved
      properties in the Gulf of Mexico, the Greater Green River Basin in
      Wyoming, and our coalbed methane project at Hanging Woman
      Basin. | 
| ·       | Abandonment and Impairment of
      Unproved Properties.  During the year, we abandoned or
      impaired $39.0 million related to unproved
      properties.  Approximately $13.4 million was related to acreage
      to which we had assigned value in 2007 acquisitions targeting the Olmos
      shallow gas.  The remaining write-offs were related to acreage
      we believe we will not be able to hold due to current limited capital
      availability and to acreage that we do not believe is
      prospective. | 
| ·       | Drilling
      Results.  Reserve additions of 170.1 BCFE from drilling
      activities were driven primarily by results in the Mid-Continent and
      Permian Basin regions, with those regions contributing 43 percent and 22
      percent, respectively, to our drilling additions.  The ArkLaTex
      and Rocky Mountain regions contributed 14 percent and 15 percent,
      respectively, to our drilling additions.  The Mid-Continent
      region had a very strong year.  Additions in the Mid-Continent
      region were derived principally by successful drilling by us and our
      operating partners in the horizontal Woodford shale formation in the
      Arkoma Basin, as well as positive results from a program targeting the
      deep Springer interval in the Anadarko Basin.  In the Permian
      region, additions were the result of successful drilling in our Wolfberry
      tight oil program.  The ArkLaTex region added reserves from
      successful Cotton Valley formation development drilling by us at Carthage
      Field and by an operating partner at Elm Grove Field.  Coalbed
      methane projects at Atlantic Rim and in Hanging Woman Basin accounted for
      the majority of drilling additions in the Rocky Mountain
      Region. | 
| ·       | Potential Resource Play
      Additions.  In 2008 we established meaningful positions
      in several new potential resource plays which emerged in the exploration
      and development industry, principally the Haynesville shale, the Eagle
      Ford shale, and the Marcellus shale.  Although no proved
      reserves have been booked in any of these emerging resource plays at the
      end of 2008, each of these plays could provide for significant future
      growth in reserves and production if development proves
      successful.  The Haynesville shale emerged early in 2008 in
      North Louisiana and East Texas and quickly became the hottest resource
      play in the country.  As a result of our previous Cotton Valley
      and James Lime activity and the acquisition of additional properties in
      Panola County, Texas in early 2008, we now have approximately 50,000 net
      acres that could be prospective for the Haynesville shale.  Our
      Eagle Ford shale position in the Maverick Basin in South Texas was seeded
      through two acquisitions in 2007 and then built through leasing efforts
      and a joint venture over the course of 2008.  If we earn all of
      the acreage available under the joint venture, St. Mary will control
      approximately 210,000 net acres in this play.  Lastly, late in
      2008 we entered into two arrangements that allow us to earn up to 43,000
      net acres in the Marcellus shale in north central
      Pennsylvania. | 
| ·       | Divestiture of Non-Strategic
      Properties.  In 2008 we sold a number of non-strategic
      properties in an effort to optimize our portfolio.  Prior to
      this year we had been a limited seller of assets.  The primary
      objectives of these sales were to dispose of properties with limited
      upside drilling potential and to focus our employees on the core strategic
      assets that will help the Company grow in the future.  During
      2008 we sold 61.4 BCFE of reserves, the vast majority of which were proved
      producing.  The sales occurred throughout the year and we
      received $178.9 million in proceeds from these sales.  The
      properties we sold were located primarily in the Rocky Mountain and
      Mid-Continent regions. | 
| ·       | Senior Management
      Change.  On March 21, 2008, David Honeyfield, Senior Vice
      President - Chief Financial Officer and Secretary, resigned as an officer
      of St. Mary, to pursue an opportunity in an unrelated
      industry.  On September 8, 2008, A. Wade Pursell joined St. Mary
      as Executive Vice President and Chief Financial Officer.  Mr.
      Pursell was employed at Helix Energy Solutions as Chief Financial Officer
      from 2000 until mid-2008 and as Vice President – Finance and Treasurer
      from 1997 through 2000.  Prior to that, he spent nine years in
      the audit practice of Arthur Andersen in positions of increasing
      responsibility. | 
| ·     | Repurchase of Common
      Stock.  During the first quarter of 2008, we repurchased
      a total of 2,135,600 shares of common stock in the open market for a
      weighted-average price of $36.13 per share, including
      commissions.  At the time we repurchased our shares, we entered
      into hedges for a commensurate amount of our production that was
      represented by the share repurchase in order to lock in the discounted
      price at which we believed our shares were trading.  As of the
      date of this filing, we are authorized by the Board to repurchase
      3,072,184 additional shares under our share repurchase
      program.  The shares may be repurchased from time to time in
      open market transactions or in privately negotiated transactions, subject
      to market conditions and other factors, including certain provisions of
      our existing credit facility agreement and compliance with securities
      laws.  Stock repurchases may be funded with existing cash
      balances, internal cash flow, and/or borrowings
  under | 
|  | the
      credit facility.  Given current economic conditions, we do not
      currently anticipate that in the near term we will be utilizing our
      liquidity and capital resources for capital investment to conduct stock
      repurchases. |

| (1)   | In
      May 2006 the stockholders approved the 2006 Equity Plan to authorize the
      issuance of restricted stock, restricted stock units, non-qualified stock
      options, incentive stock options, stock appreciation rights, and
      stock-based awards to key employees, consultants, and members of the Board
      of Directors of St. Mary or any affiliate of St. Mary.  The 2006
      Equity Plan serves as the successor to the St. Mary Land &
      Exploration Company Stock Option Plan, the St. Mary Land & Exploration
      Company Incentive Stock Option Plan, the St. Mary Land & Exploration
      Company Restricted Stock Plan, and the St. Mary Land & Exploration
      Company Non-Employee Director Stock Compensation Plan (collectively
      referred to as the “Predecessor Plans”).  All grants of equity
      are now made out of the 2006 Equity Plan, and no further grants will be
      made under the Predecessor Plans.  Each outstanding award under
      a Predecessor Plan immediately prior to the effective date of the 2006
      Equity Plan continues to be governed solely by the terms and conditions of
      the instruments evidencing such grants or issuances.  In late
      2007, St. Mary transitioned to PSA grants as the primary form of long-term
      equity incentive compensation for eligible employees in place of grants of
      RSUs.  The Company’s Board of Directors approved an amendment
      and restatement of the 2006 Equity Incentive Compensation Plan on March
      28, 2008, and the amended plan was approved by stockholders at the
      Company’s annual stockholders’ meeting May 21, 2008.  Awards
      granted in 2008, 2007, and 2006 under the 2006 Equity Plan and the
      Predecessor Plans were 932,767, 135,138, and 547,678,
      respectively. | 
| (2)   | Under
      the St. Mary Land & Exploration Company Employee Stock Purchase Plan
      (the “ESPP”), eligible employees may purchase shares of the Company’s
      common stock through payroll deductions of up to 15 percent of their
      eligible compensation.  The purchase price of the stock is 85
      percent of the lower of the fair market value of the stock on the first or
      last day of the purchase period, and shares issued under the ESPP are
      restricted for a period of 18 months from the date issued.  The
      ESPP is intended to qualify under Section 423 of the Internal Revenue
      Code.  Shares issued under the ESPP totaled 45,228, 29,534, and
      26,046 in 2008, 2007, and 2006,
respectively. |

| ·       | A
      $0.10 increase in recurring lease operating expense on a per MCFE basis is
      related to higher costs, particularly in oil-weighted regions, for items

      interest in properties | |||||
| located
      in Upton and Midland Counties, Texas and $17.6 million in
      cash. | |||||
| In
      September 2008 the Company hired a new senior executive.  Upon
      commencement of employment, the | |||||
| Company
      issued 15,496 shares of restricted stock awards to the senior executive,
      of which half will vest on | |||||
| December
      15, 2009 and the remaining half will vest on December 15, 2010, provided
      that on such vesting dates the | |||||
| executive
      is employed by the Company.  The total fair value of the
      issuance was $600,005. | |||||
| In
      August 2008 the Company issued 465,751 Performance Share Awards to
      employees as equity-based | |||||
| compensation
      pursuant to the Company's 2006 Equity Incentive Compensation
      Plan.  The total fair value of the | |||||
| issuance
      equaled $12.3 million. | |||||
| For
      the years ended December 31, 2008, 2007, and 2006, the Company issued
      428,407, 102,634, and 492,851 | |||||
| restricted
      stock units, respectively, to employees as equity-based compensation

      Incentive Compensation Plan.  The total fair values of the
      issuances were $23.4 million, $3.3 million, and | |||||
| $16.7
      million, respectively. | |||||
| As
      of December 31, 2008, 2007, and 2006, $116.5 million, $116.9 million, and
      $73.5 million, respectively, are included as | |||||
| additions
      to oil and gas properties and accounts payable and accrued
      expenses.  These oil and gas property | |||||
| additions
      are reflected in cash used in investing activities in the periods that the
      payables are settled. | |||||
| For
      the years ended December 31, 2008, 2007, and 2006, the Company issued
      23,113, 32,504, and 29,827 shares, | |||||
| respectively,
      of common stock from treasury to its non-employee directors pursuant to
      the Company's 2006 Equity | |||||

      2007, and 2006, respectively. | |||||
| In
      March 2007 the Company called the 5.75% Senior Convertible Notes for
      redemption.  All of the note holders | |||||
| elected
      to convert the 5.75% Senior Convertible Notes to common stock.  As a
      result, the Company issued | |||||
| 7,692,295
      shares of common stock on March 16, 2007, in exchange for the $100 million
      of 5.75% Senior | |||||
| Convertible
      Notes then outstanding.  The conversion was executed in accordance
      with the conversion provisions | |||||
| of
      the original indenture.  Additionally, the conversion resulted
      in a $7.0 million decrease in non-current deferred | |||||
| income
      taxes payable and a corresponding increase in additional paid-in capital
      that resulted from the recognition | |||||
| of
      the cumulative excess tax benefit earned by the Company associated with
      the contingent interest feature of | |||||
| the
      notes. | |||||
| In
      June 2006 the Company hired a new senior executive.  In doing
      so, the Company issued 13,784 shares of
    stock.  The | |||||
| fair
      value of this issuance was $727,600.  In February 2008 and 2007,
      the Company issued 3,750 and 1,250 shares | |||||
| of
      stock, respectively, to the senior executive, as the Company achieved
      certain performance metrics under an | |||||
| agreement
      with the executive.  The total fair values of these issuances
      were $141,900, and $45,012, respectively. | |||||
| In
      May 2006 the Company closed a transaction whereby it exchanged non-core
      oil and gas properties for oil | |||||
| and gas properties located in Richland County, Montana. This transaction is considered a non-monetary | |||||
