4

The theme to last year’s 2006 annual report was “Transitions.”  In that report we described the

various transitions St. Mary has made over its 100 year history — from passive oil and gas royalty

owner to a fully functioning multi-billion dollar exploration and production company. In 2007, the

“Transitions” theme continued. I was named CEO early in the year when Mark Hellerstein retired

after leading the Company for 15 years. We continued the transition of our asset base toward

more concentrated asset groups comprised of low risk, repeatable resource plays. One way we did

this was with two acquisitions in South Texas targeting the Olmos shallow gas formation. Another

way was our initiation of a marketed divestiture package of non-core assets during the year. This

sale closed in January of 2008 for $131 million. Management also continued to transition during

2007 as we saw new leaders appointed to head four of our five regional offices.

This brings us to the theme of this year’s annual report: “Energized for 100 years… and moving

forward.” In early 2008, we celebrate our 100th anniversary. This is a tremendous accomplishment

for any business, particularly in an industry that sees as much consolidation as the exploration and

production industry. Our longevity is proof that St. Mary has been successful at delivering value

to its owners for a very long period of time. We plan to celebrate this anniversary with gatherings

at each of our offices early in the year, capped off with a special event at the New York Stock 

Exchange where we will ring the closing bell. Our 100 years of success has been achieved with a

focus on creating value for our stockholders. We intend to continue this tradition.  

2007 Performance and Highlights

5

The Company’s operational and financial highlights for 2007 include the following:

(cid:129) Proved reserves grew 17% year over year to 1,087 BCFE, which is a record for the Company

both in absolute terms and on a per share basis.

(cid:129) Record average daily production of 294.5 MMCFE per day, up 16% year over year. This was a

record on a per diluted share basis as well.

(cid:129) Record net cash provided by operating activities of $630.8 million, up 35% year over year.

(cid:129) Net income of $189.7 million and diluted earnings per share of $2.94 per share.

(cid:129) All-in reserve replacement percentage of 248%, an improvement from 244% in the prior year.

(cid:129) All-in finding costs of $3.48 per MCFE, down from $3.56 per MCFE in 2006.

These 2007 results were driven by an active acquisition and capital development plan whereby

St. Mary invested $926 million in acquisition, development, and leasing activities. The Company

deployed $741 million on exploration and development projects during the year, which was an

increase from the $523 million spent in 2006. Highlights of our 2007 regional programs include

the following:

6

MID-CONTINENT — In 2007, we invested $186 million in the Mid-Continent region on exploration,

development, and acquisition activities. Throughout 2007, we maintained a consistent level of 

activity in the Arkoma Basin in order to advance our horizontal Woodford shale program where we

continued to refine our understanding of the play. Our results for this program were significantly

better in the second half of the year as we gained experience in the overall completion and design

methodology for these wells together with an increased understanding of the underlying geology,

all of which translated into enhanced performance. We decreased our activity in the Atoka/Granite

Wash development program while working to develop and implement a more cost efficient 

completion design for these wells. Several exploration wells were also drilled by this regional 

office in 2007. The most exciting of these tested deeper sections of the Anadarko Basin, which

we believe validated a geologic idea that we plan to test further in 2008.  

ARKLATEX — The ArkLaTex region invested $150 million in 2007. This is 70% more than the $88

million spent in 2006. The primary drivers of this increase in capital investment were increased

activity levels in our James Lime and Cotton Valley programs. In the St. Mary operated horizontal

James Lime program, we operated one rig continuously throughout 2007. We continued to see solid

results in proven development areas and had two successful test wells during the year that 

extended the play westward by a number of miles. We believe that we have identified a trend that

is roughly 75 miles in length that could be prospective for the James Lime. During 2007, we 

increased our acreage position along that trend to approximately 50,000 net acres. Our team in

Shreveport has been successfully drilling and completing horizontal James Lime wells for a number

of years, and we believe we are one of the better operators in the play. The partner operated 

Cotton Valley programs at Elm Grove and Terryville fields were areas of significant investment 

in 2007. At Elm Grove Field, advancements such as 20-acre increased density drilling and

commingling of production from the Cotton Valley and Hosston formations have benefited us, 

particularly as development has moved into areas where we have larger working interests. There

is an old adage in the exploration and production business that “good fields get better ”— this is

certainly the case with Elm Grove. At Terryville Field, despite more difficult operating conditions

resulting from the Cotton Valley formation being deeper and more highly pressured compared to

Elm Grove Field, operations there were highly successful in 2007 and allowed for sustained activity

during the year.

GULF  COAST — Our capital expenditures in the Gulf Coast region grew significantly from $66

million in 2006 to $279 million in 2007, primarily driven by two significant acquisitions totaling

$179 million. These were the $149 million Rockford acquisition that closed in October 2007 and

the $30 million Catarina acquisition, which closed in April 2007. Both of these target the Olmos

shallow gas formation and are located in the greater Maverick Basin in South Texas. St. Mary had

been interested in the Olmos formation for some time, and we are pleased that we were able to

enter the play in a meaningful way in 2007. We are the operator of these recently acquired 

assets and our emphasis in 2007 was the integration of these properties into our operations.

While the core focus of the region shifted toward onshore projects, we continued to be active off-

shore in 2007. The previously discovered Zloty intermediate deepwater project began production

late in the year, and other intermediate deepwater projects in which we are a partner continued to

advance. We were also active closer to shore with a program that included the successful Reno,

Clement, and Amber Jack wells. We have benefited from the meaningful production associated with

some of these longer lead time projects.

9

PERMIAN — St. Mary began 2007 with no regional office in the Permian Basin. That changed 

in February when we opened a regional office in Midland, Texas to manage the Sweetie Peck 

properties acquired in December 2006. Throughout 2007, we continued to build our Midland staff

and as of the date of this letter we are now fully staffed in this regional office. During 2007, this

region invested $135 million. The majority of this investment was deployed to develop projects that

target the Wolfcamp and Spraberry formations, commonly referred to as the “Wolfberry.”  We 

participated in two substantial Wolfberry programs during the year — the operated Sweetie Peck

program and the outside operated program at Halff East. We operated between two and five drilling

rigs at Sweetie Peck throughout 2007. Our efforts in the Sweetie Peck program have focused on

improving our operating efficiencies. Throughout 2007, we significantly improved our rig fleet and

transitioned the drilling operations in-house once the Midland office was fully staffed. We antici-

pate that these improvements will benefit our program here in the years to come. At Halff East,

our operating partner had two drilling rigs running continuously throughout the year. During the

year, we also invested capital in the Parkway and East Shugart Delaware waterflood projects.

ROCKY  MOUNTAIN — In 2007, St. Mary invested $178 million in the Rocky Mountain region,

compared to $161 million in 2006. The 2007 amount included $36 million of capital invested in

the Hanging Woman Basin coalbed methane project. The 2007 conventional program focused on

a horizontal development in the Mississippian formations of the Williston Basin and the drilling of

Bakken formation infill locations in Montana.

As a result of our active 2007 program, the Company reached a significant milestone in 2007 as

its proved reserves surpassed 1 TCFE. As of December 31, 2007, St. Mary had proved reserves of

1,087 BCFE, of which 77% were proved developed and 56% were natural gas. This is a significant

threshold for any independent E&P company since every day its assets are depleting as they are

produced. The ability to economically grow reserves is critical for the ongoing success of any

company in our industry. At St. Mary, our long-standing goal is to annually replace 200% of that

year’s production. In 2007, we met this goal by replacing 248% of our reserves produced in 2007

on an all sources basis. Our 3 year and 5 year average reserve replacement percentages were

249% and 235%, respectively. What is particularly important for stockholders is that St. Mary

has consistently grown proved reserves on a per share basis while incurring moderate levels of

debt. We replaced 88% of our 2007 produced reserves through acquisitions in 2007, which is 

in-line with our historic average for acquisition reserve replacement. Acquisitions have historically

been a significant part of the St. Mary business plan, and we believe they will continue to play an

important role in our future strategy.

Our 2007 all-in finding cost for proved reserves was $3.48 per MCFE, down from $3.56 per MCFE

in 2006. We believe that it is important to look at longer time periods when analyzing this metric

due to the differences in timing as to when capital is invested and when proved reserves are

booked. Our 3 and 5 year averages for all-in finding costs on a per MCFE basis were $3.01 and

$2.61, respectively. Finding costs in the industry have generally increased in recent years as

costs to acquire or develop proved reserves have increased in correlation to commodity prices.

Although finding costs only tell part of the story with respect to the economics of a company’s

investments, we realize that finding costs are an important metric used to evaluate and compare

St. Mary has grown value for 

its owners for 100 years, 

and is focused on building value

as it enters its second century.

12

the costs at which companies are adding reserves. Accordingly, we are very focused on reducing

costs and making portfolio changes that will allow us to improve on this metric.

Production in 2007 set a new record for St. Mary, both in absolute terms and on a per share basis.

Total production for the year was 107.5 BCFE, or an average daily rate of 294.5 MMCFE per day.

For the full year, approximately 60% of the Company’s production was natural gas and roughly

40% was oil. This record production combined with strong commodity prices during the year, 

particularly for oil, resulted in solid net income and cash flow from operating activities. Production

growth in 2007 was driven primarily by strong contributions from the Permian, ArkLaTex, and Mid-

Continent regions. The strong cash flows that we enjoyed during the year allowed us to maintain

the strong balance sheet for which St. Mary is known.

Plans for 2008

We are entering 2008 on solid footing both financially and operationally. We have a business plan

that we believe will deliver growth and value for our stockholders. Our debt-to-book capitalization

ratio as of the end of 2007 was 40%. When adjusted for the proceeds received from the divestiture

of non-core properties that closed on January 31, 2008, our pro forma debt-to-book capitalization

ratio stands at 34%. Currently, we are generating strong cash flows. We enjoy the benefits of 

having oil as a significant portion of our production profile. Opportunistic natural gas hedges have

helped our realized natural gas revenues stay strong. Operationally, 2008 offers the strongest 

inventory of projects that we have had since I joined St. Mary in 2006. We have a multi-year

drilling program in nearly every region that when taken together make clearly visible the 

Company’s path for continued growth. The foundation of our property base was strengthened by

the divestiture of non-core assets referred to earlier — not only have we removed lower growth

properties from our portfolio, but now our employees can focus more of their efforts on the assets

13

that offer more upside potential for the Company.

Our initial 2008 exploration and development budget is $626 million. We believe that this budget

level will improve the capital efficiency of our investments and enhance the strength of our balance

sheet to maintain financial flexibility in the future. This budget level also provides solid organic 

production growth for the Company. Programs that failed to meet our return criteria in 2007 were

either omitted or substantially reduced if they warranted further study. Accordingly, we anticipate

operating cash flows will exceed our drilling capital budget during the year. This will provide us the

financial flexibility to accelerate successful drilling programs, pursue potential acquisition oppor-

tunities, consider repurchases of outstanding shares of common stock, or repay bank borrowings

with excess cash flows. Highlights of the Company’s 2008 exploration and development plan 

are as follows:

ARKLATEX — The largest regional capital program in 2008 will be in the ArkLaTex region, which

will focus on Cotton Valley and James Lime programs. Of the capital allocated for Cotton Valley

programs in 2008, a little over half will be invested at Elm Grove Field in northern Louisiana where

development continues to be highly successful. Further development of the field on 20-acre 

spacing and highly economic uphole recompletions continue to drive activity in this play, which

becomes more meaningful to St. Mary as activity moves onto acreage where we have a larger

working interest. A successful horizontal Cotton Valley well completed at the end of 2007 has

raised the prospect that the field could be further developed with horizontal wells. Our operating

partner is currently drilling an offset to the initial horizontal test which, if successful, could

of 20% to stockholders since its IPO in 1992.

15

substantiate a horizontal development plan at Elm Grove Field. The remaining Cotton Valley 

allocation for 2008 will be split between the program at Terryville Field and the St. Mary operated

program in East Texas. Subsequent to year end, St. Mary acquired additional producing and non-

producing properties in Panola County, Texas, which are adjacent to existing St. Mary leasehold.

These assets target the Cotton Valley formation, a formation in which we are increasingly interested.

As operator, we plan to drill several horizontal and vertical wells in the area in 2008. We believe

that our experience in the region, particularly in drilling horizontal James Lime wells, will be an 

advantage that we can exploit as we pursue a more active operated Cotton Valley program in the

future. In the operated horizontal James Lime program, we plan to have a more aggressive program

in 2008 with two operated rigs budgeted to run continuously throughout the year. We continue to

be active acquirers of leasehold in the play. We have been involved with this program for a number

of years and believe we are a leader in the play.

MID-CONTINENT — The largest component of our 2008 Mid-Continent plan is the horizontal

Woodford shale program in the Arkoma Basin. Our budget anticipates that we will drill ten hori-

zontal Woodford wells with two operated rigs in the first half of 2008, and continue to participate

with our partners in outside operated wells. As I mentioned earlier, we have seen results improve

recently in the horizontal Woodford program. With continued success in the play, we have the 

ability to increase our capital investment in the program in the second half of 2008. We also plan

to continue with an exploration program in the Anadarko Basin that yielded encouraging results in

2007. This exploration program targets some of the deeper formations of the basin. In our Western

Oklahoma Washes program in the Anadarko Basin, previously referred to as the Mayfield devel-

opment area, we plan to invest capital in wells that target the Atoka and Granite Wash formations.

16

The area is a known hydrocarbon province. Our development efforts in 2008 will feature enhanced

geotechnical efforts and revised drilling and completion techniques, both of which should improve

the economic performance of this program.

GULF  COAST — Our development and exploration budget in the Gulf Coast region for 2008 is 

focused on the evaluation and exploitation of the two Olmos shallow gas projects that we acquired

in South Texas during 2007. Our technical team in Houston is in the process of reinterpreting

seismic data that covers a large portion of our acreage. Approximately half of the budgeted 

capital will be deployed to drill new Olmos wells, with additional capital being invested in a 

number of recompletion opportunities. We anticipate that the addition of this resource play will

provide focus and a visible inventory of projects for our Gulf Coast team. We will also invest capital

in production facilities for an intermediate deepwater discovery from 2005 that is expected to

be brought online in early 2009.

PERMIAN — The majority of capital investment made in the Permian in 2008 will be in properties

targeting the Wolfberry interval. At Sweetie Peck, we plan to operate three drilling rigs continuously

throughout the year. Included in the budget are investment dollars to test several 40-acre pilot

areas that could add meaningful proved reserves if successful. We expect to see increased 

operating efficiency on the investments we made in 2007 related to high-grading our rig fleet 

and bringing the drilling operations in-house. At the Halff East Wolfberry development area, we 

will continue to invest with our operating partner. We will also be investing in several smaller 

programs, including our Delaware waterfloods.

17

ROCKY MOUNTAIN — The 2008 plan for the Rockies is smaller than in years past. In the 

conventional Rockies program, six vertical wells and two recompletions in the Red River are

planned for 2008. We also plan to drill a small number of horizontal Bakken wells in and around

our historic Bakken development areas in Montana. We expect to participate in a handful of wells

in the North Dakota Bakken play that has received so much attention in the past year. Our plan

also includes workover and recompletion operations in our Wind River Basin and Big Horn Basin

oil properties. At the outside operated Atlantic Rim coalbed methane play in the Green River

Basin, we expect to see activity ramp up since regulatory and environmental delays appear to 

have been resolved. At Hanging Woman Basin, we plan to moderate our drilling activity in 2008 

focusing on completing the in-fill program in the shallow coals, monitoring the intermediate depth

wells,  and  testing  several  horizontal  completion  techniques  in  the  deeper  coals.  We  plan  to 

continue concentrating our property base in the Rocky Mountain region, and are conducting a

thorough review of our Rockies acreage position. Divestitures of non-core assets are anticipated 

in the region in the future.

Moving Forward

As mentioned earlier, the theme of this year’s annual report is “Energized for 100 years… and 

moving forward.” As we move forward into our second century, we must embrace the challenge

of adapting to new competitive and market realities. One challenge that St. Mary has worked to

address over the past two years is the state of its drilling portfolio by actively working to increase

its inventory of repeatable, multi-year drilling projects. These types of programs are advantageous

because they allow for more predictable production and reserve growth, and have the potential

for improved economics as operational efficiencies develop. Transactions such as the Sweetie

St. Mary has a consistent record of building 

value for stockholders by growing proved reserves

and production on a per share basis.

19

Peck acquisition in 2006 and the Olmos acquisitions in 2007 have added to our inventory. The 

inventory has also grown through an increased emphasis on grassroots resource programs such

as the horizontal James Lime and Woodford shale. As with any exploration and production com-

pany, we need to continue adding to our project portfolio. To that end, we have been busy in 2007

and early 2008 adding business development professionals in our Denver headquarters and in our

regional offices. The goal is simple — build the team that will economically grow the project 

inventory for the Company. As we capture more of these high quality projects in our inventory

pipeline, we will need more technical personnel to execute the development of those resources.

Accordingly, we have hired and are continuing to actively hire engineers and geologists in all of

our regional offices.  As of this letter, our total number of employees is 438, an increase of roughly

80 employees from a year ago. This talented group will drive our long-term growth in value.

With the changes outlined above, there are also certain standards that will remain unchanged. 

Values such as integrity, reliability, and a sense of stewardship for our owners and our communities

will always be prominent characteristics of St. Mary. We remain committed to being a preferred

partner, employer, and customer in the industry. We believe that this foundation of values and the

commitment of our employees will result in value creation for our stockholders.

retirement obligations, by the amount of estimated

net proved reserves added through discoveries,

extensions, infill drilling, acquisitions, and revisions

of previous estimates during the same period.  

Reserve replacement percentage. The sum of

sales of reser ves, reser ve extensions and 

discoveries, reser ve acquisitions, and reser ve 

revisions of previous estimates for a specified 

period of time divided by production for that same

period of time. This is believed to be a useful 

non-GAAP measure that is widely utilized within the

exploration and production industry as well as by

investors. It is an easily calculable number and is

representative of the relative success a company

is having in replacing its production from its 

declining asset base as well as its ability to grow

the overall company.

When we use the terms “St. Mary,” “the Company,” “we,” “us,” or “our,” we are referring to St. Mary 

Land & Exploration Company and its subsidiaries, unless the context otherwise requires.  We have included 
technical terms important to an understanding of our business under “Glossary of Oil and Natural Gas Terms”.  
Throughout this document we make statements that are classified as “forward-looking”.  Please refer to the 
“Cautionary Information about Forward-Looking Statements” section of this document for an explanation of these 
types of statements. 

ITEMS 1 and  2.  BUSINESS and PROPERTIES 

General 

We are an independent oil and gas company engaged in the exploration, exploitation, development, 
acquisition, and production of natural gas and crude oil.  We were founded in 1908 and incorporated in Delaware in 
1915.  Our initial public offering of common stock took place in December of 1992.  The common stock of the 
Company trades on the New York Stock Exchange under the ticker “SM”. 

Our principal offices are located at 1776 Lincoln Street, Suite 700, Denver, Colorado 80203, and our 

telephone number is (303) 861-8140. 

Strategy 

Our objective is to build stockholder value through consistent economic growth in reserves and 
production that increases net asset value per share.  We seek to invest in oil and gas producing assets that result in 
a superior return on equity while preserving underlying capital, resulting in a return on equity to stockholders that 
reflects capital appreciation as well as the payment of cash dividends. 

The majority of our current senior technical managers in each region possess between 20 and 30 years of 

industry experience and lead fully-staffed regional technical offices that are supported by centralized administration 
from our corporate office in Denver.  We use our comprehensive base of geological, geophysical, land, engineering, 
and production experience in each of our core operating areas to source prospects for our ongoing low-to-medium-
risk development and exploitation programs.  We conduct detailed geologic studies and use an array of technologies 
and tools including 2-D and 3-D seismic imaging, hydraulic fracturing and other reservoir stimulation techniques, 
horizontal drilling, secondary recovery, and specialized logging tools to enhance the potential of our existing 
properties.  We believe that having fully-staffed technical teams based in each of our operating regions is an 
advantage in that our regional offices are staffed with personnel that have a deep knowledge of the basins in which 
they work, participate in the regional deal flow and prefer to live in regional areas, which minimizes personnel 
attrition. 

Acquisitions have been a key element of our business strategy.  Historically, we have been most 
successful in acquiring properties on a negotiated basis, as opposed to participating in widely marketed auctions 
for properties.  In the last two years we have made several large acquisitions.  In 2007, we paid $178.9 million for 
two acquisitions in South Texas for properties targeting the Olmos shallow gas formation.  In 2006, we paid 
$243.1 million to acquire assets that target the Wolfberry section in the Permian Basin. 

We divest selected non-core assets when market conditions and prices are attractive.  We will continue to 

evaluate such opportunities in the future when we believe it to be appropriate.  During 2007, we sold properties 
with estimated proved reserves of 1.4 BCFE.  We actively marketed and contracted to sell a package of non-core 
assets in 2007.  This sale closed on January 31, 2008, for a total adjusted sales price of $131.1 million before 
commissions; this sale represented 40.4 BCFE of our year-end 2007 proved reserves.  We utilized a 1031 reverse 
exchange structure to defer the recognition of income tax on the gain from this sale.   

Conservative use of financial leverage has long been a critical element of our strategy.  We believe that 

maintaining a strong balance sheet is a significant competitive advantage that enables us to pursue acquisitions and 

1 

other opportunities, particularly in weaker price environments.  It also provides us with the financial resources to 
weather periods of volatile commodity prices or escalating costs.  Our debt to book capitalization ratio was 
40 percent at the end of December 2007.  The proceeds from the aforementioned property sale in January 2008 were 
applied to reducing bank borrowings.   

In summary, we believe that our dedication to making investment decisions based on net asset value per 
share, our long-standing geologic and engineering experience in the regions in which we operate, our appropriate 
application of technology, our established networks of local industry relationships, and our measured approach to 
acquisitions and divestitures all provide us with competitive advantages that we can use to continue growing the 
Company. 

Significant Developments in 2007 

• 

Increase in 2007 Year-End Reserves.  Proved reserves increased 17 percent to 1,086.5 BCFE at 
December 31, 2007, from 927.6 BCFE at December 31, 2006.  We added 132.1 BCFE from our drilling 
program and 94.8 BCFE from acquisitions.  We had a positive revision of 40.9 BCFE which consisted 
of a 6.4 BCFE upward performance revision and an upward revision of 34.5 BCFE due primarily to 
increased oil prices at the end of 2007.  The 2007 acquisition volumes are lower than the initial 
estimates previously disclosed as a result of the final year-end reservoir engineering estimation.  We 
sold properties with reserves of 1.4 BCFE in 2007. 

•  Drilling Results.  Reserve additions from drilling activities of 132.1 BCFE were driven by results in the 
Mid-Continent, Rocky Mountain, ArkLaTex, and Permian regions, with those regions contributing 
37 percent, 21 percent, 20 percent, and 18 percent, respectively.  Additions in the Mid-Continent were 
driven principally by successful drilling by us and others in the horizontal Woodford shale formation in 
the Arkoma Basin, as well as positive results in two programs in the Anadarko Basin.  In the Rocky 
Mountain region, the largest contribution came from the Hanging Woman Basin where we added 
9.9 BCFE of proved reserves.  The ArkLaTex region added 26.2 BCFE from successful drilling 
operations in the James Lime carbonate program and Elm Grove Field.  Successful results in the 
Wolfberry program in 2007 were the principal driver of drilling additions in the Permian Basin. 

•  New Basin Entry in 2007.  In 2007 we spent $182.9 million for acquisitions of proved and unproved oil 
and gas properties.  We entered the greater Maverick Basin with two acquisitions in South Texas 
totaling $178.9 million that target the Olmos shallow gas formation.  The first was the $30.0 million 
Catarina acquisition that closed in June 2007.  The more significant transaction was the $148.9 million 
Rockford acquisition that closed in October 2007.  These properties added a sizeable inventory of lower 
risk drilling locations to our portfolio.  Consistent with prior acquisitions, we hedged several years of 
the risked production related to these acquisitions at the time of acquisition.  The remaining acquisitions 
in 2007 were small niche transactions throughout the year in the Mid-Continent, ArkLaTex, and Rocky 
Mountain regions. 

•  Senior and Regional Management Changes.  During 2007, the Company underwent or announced 
personnel changes in the chief executive position and in several regional manager positions.  On 
February 23, 2007, Mark Hellerstein retired as Chief Executive Officer after serving in that role since 
1995.  Tony Best, President of the Company, was appointed as Chief Executive Officer on that date.  
Mr. Hellerstein continues to serve as the Chairman of the Board.  In June of 2007, Jerry Schuyler, the 
Senior Vice President responsible for the Gulf Coast and Permian regions, left St. Mary to pursue 
another professional opportunity.  Greg Leyendecker, then Operations Manager for the Gulf Coast 
region, assumed responsibility for the Gulf Coast and is now Vice President - Regional Manager of the 
Gulf Coast region.  We also made the Midland office a stand-alone regional office headed by 
Lehman Newton III, Vice President - Regional Manager of our Permian region.  Mr. Leyendecker and 
Mr. Newton joined St. Mary in 2006 and each have over 25 years of management and operational 
experience in the oil and gas industry.  In July 2007, Stephen Pugh joined the Company as Senior Vice 
President and Regional Manager of the ArkLaTex region.  Mr. Pugh succeeded David Hart, who retired 
from St. Mary after 15 years in various roles at the Company.  Mr. Pugh came to St. Mary with over 

2 

25 years of engineering, operations, and business development experience in the oil and gas industry.  In 
August of this year, Robert Nance, Senior Vice President - Regional Manager of the Rocky Mountain 
region, announced his decision to retire in the first quarter of 2008 after more than 40 years in the oil 
and gas industry.  Mark Mueller joined us as Senior Vice President in August and now leads our Rocky 
Mountain region.  Mr. Mueller has over 20 years of management and technical experience in the oil and 
gas industry.  Effective January 1, 2008 Mark Mueller was appointed Senior Vice President - Regional 
Manager.  Subsequent to year end, David Honeyfield, Senior Vice President - Chief Financial Officer, 
announced that he will resign as an officer of St. Mary on March 21, 2008, in order to pursue an 
opportunity in an unrelated industry.  An external search for his successor is underway at the time of 
this filing. 

•  2007 Capital Markets Activity.  In March of 2007 we called for redemption of the then outstanding 

$100.0 million 5.75% Senior Convertible Notes.  The notes had a conversion price of $13.00 per share.  
One hundred percent of the holders of the notes elected to convert their notes into shares of common 
stock.  As a result of the conversion, 7.7 million shares of stock were issued to the note holders.  This 
resulted in a decrease to long-term debt of $100.0 million, and an increase to common stock associated 
with the conversion together with the recognition of the excess tax benefit associated with the 
contingent interest feature associated with the notes. 

In April of 2007, we completed the sale of $287.5 million of 3.50% Senior Convertible Notes.  The net 
proceeds from the 3.50% Senior Convertible Notes were used to repay outstanding borrowings under 
our revolving credit facility. 

•  Significant Volatility in Commodity Prices.  During 2007, the exploration and production sector was 
impacted by volatility in the prices for crude oil and natural gas.  Our operations and financial 
conditions were 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.  NYMEX crude oil began 
2007 with an average January price of $54.67 per barrel and increased steadily throughout the year, 
reaching an average monthly high for the year of $94.63 per barrel in November.  The average 
NYMEX price for the year was $72.34 per barrel.  Geopolitical unrest in various producing regions 
overseas and concerns domestically related to refinery utilization and petroleum product inventories 
were the principal drivers of the increase in oil prices in 2007. 

We sell the majority of our natural gas on contracts which 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 $6.86 per MMBtu in 2007, which was five percent 
lower than the average for 2006.  High levels of natural gas in storage had an impact on pricing 
during 2007 as inventory levels exceeded the five year average for all of 2007.  Concerns about 
supply overhang peaked for the year around September of 2007, leading to the lowest Henry Hub 
price for the year of $5.43 per MMBtu.  The impact was more acute in the Rocky Mountain region 
where bid week prices were driven down to $2.13 per MMBtu and $1.11 per MMBtu for September 
and October, respectively, on the Colorado Interstate Gas (CIG) index.  A significant portion of our 
production in the Rockies is oil and we had limited exposure to the CIG hub.  Additionally, recent 
acquisitions have added a richer gas stream to our overall production mix.  The value received 
associated with natural gas liquids (NGLs) from this rich gas stream align more closely with crude oil 
prices.  The increase in crude prices has had a similar impact on prices for NGLs, and as a result we 
have enjoyed higher realized natural gas prices.   We hedge a portion of our oil and gas production 
using swaps and collars.  A gain of $58.7 million was realized on our natural gas hedges for the year 
and a loss of $34.3 million was realized on our oil hedges for the year. 

•  Repurchase of Common Stock. In 2007, we repurchased a total of 792,216 shares of our common 

stock in the open market for a weighted-average price of $32.76 per share, including commissions, 
under this program.  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 our shares were trading.  As of the date of this filing, we are 

3 

authorized by the Board to repurchase 5,207,784 additional shares under this 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 borrowings under the credit facility.   

Assets 

As of December 31, 2007, we had estimated proved reserves of 78.8 MMBbl of oil and 613.5 Bcf of 

natural gas.  Prices in effect on December 31, 2007, used to estimate proved reserves were $6.80 per MMBtu of 
gas and $95.98 per barrel of oil.  On an equivalent basis, our proved reserves were 1,086.5 BCFE as of 
December 31, 2007, an increase of 17 percent from 927.6 BCFE at the end of the prior year.  The increase in 
proved reserves in 2007 was the result of development activities and acquisitions.  On an equivalent basis, 
77 percent of our proved reserves are classified as proved developed as of year-end.  Total proved oil and gas 
reserves have a before income tax PV-10 value of $3.9 billion and a standardized measure value, which includes 
the effect of income taxes, of $2.7 billion (a reconciliation between these two amounts is shown under Reserves in 
Part I, Items 1 and 2).  During 2007, our average daily production was 181.0 MMcf of gas and 18.9 MBbl of oil, 
for an average equivalent production rate of 294.5 MMCFE per day, which is a new annual record for us.  We 
sold certain non-core oil and gas properties subsequent to year end; all production and reserve information 
presented is before the impact of this sale unless otherwise noted. 

Our reserve replacement percentage – including sales for 2007 was 248 percent, which includes 
1.4 BCFE of asset sales that occurred during the year.  Our reserve replacement percentage – excluding sales was 
249 percent.  We acquired 94.8 BCFE of proved reserves through acquisitions in 2007, the majority of which 
relate to the two Olmos shallow gas acquisitions in South Texas.  We believe the use of the phrase “reserve 
replacement percentage” is widely understood by those who make investment decisions related to the oil and gas 
exploration business.  We believe that this measure is useful in evaluating and comparing exploration and 
production companies and provides a measure of the growth of a company.  The Glossary includes a definition of 
“reserve replacement percentage” and description of how it is calculated. 

In 2007, we invested a total of $926.1 million on drilling activities and acquisitions.  This was 15 percent 

higher than the $805.5 million invested in 2006.  Drilling investments, including leasing activity, in 2007 of 
$740.9 million comprised 80 percent of our total capital investment budget for the year and compares to 
$522.6 million in 2006.  The increase in drilling activity was driven primarily by development of the Sweetie 
Peck asset in the Permian Basin that was acquired in late 2006 as well as increases in activity in our ArkLaTex 
region.  We invested $185.2 million on acquisitions in 2007, the majority of which related to the two acquisitions 
in South Texas targeting the Olmos shallow gas play. 

We have $626 million budgeted for development and exploration investments in 2008, which is a decrease 
of 16 percent from the $740.9 million invested in drilling activities in 2007.  The decrease in investment year over 
year is a reflection of our goal to improve our capital efficiency and to invest within our cash flow from operations in 
order to maintain financial flexibility so that we can deploy additional capital where warranted in order to make 
accretive acquisitions, repurchase stock, or repay debt.

Note:  The table above includes production and proved reserves related to non-core assets that were divested on 
January 31, 2008.  The properties divested were primarily in the Mid-Continent and Rocky Mountain regions.  These non-
core properties contributed 5.0 BCFE of production during 2007 and represented 40.4 BCFE of proved reserves at 
December 31, 2007. 

ArkLaTex Region.  St. Mary’s operations in the ArkLaTex region are managed from our office in 
Shreveport, Louisiana.  The ArkLaTex region was the first operating office for the Company, originating from an 
acquisition in 1992.  For years the activities of this region focused on the tight sandstone Cotton Valley and Travis 
Peak formations in the region.  In recent years, we have utilized horizontal wells in the development of limestone 
carbonates found in the region, particularly the James Lime formation. 

The ArkLaTex region invested $149.8 million in 2007 on exploration, development, and acquisition 

activities, which is 70 percent higher than the $88.0 million spent in 2006.  The primary drivers of this increase in 
capital were increased activity levels in our James Lime and Cotton Valley programs during the year.  In the 
St. Mary operated horizontal James Lime program, we operated one rig continuously throughout 2007.  We 
continued to see solid results in proven development areas and had two successful wells that extended the play 
westward by approximately 75 miles.  The Cotton Valley programs at Elm Grove and Terryville fields were areas of 
significant investment in 2007, although these are operated by other companies.  At Elm Grove Field, advancements 
such as 20-acre increased density drilling, commingling of production of the Cotton Valley and Hosston formations, 
and horizontal drilling have benefited us, particularly as development has moved into areas where we have larger 
working interests.  Even though operations at Terryville Field are more difficult due to the formation being deeper 
and more highly pressured than the Cotton Valley formation at Elm Grove Field, operations in the field were highly 
successful in 2007 and allowed for sustained activity during the year.  The region’s 2007 production increased 
31 percent to 13.8 BCFE.  Our proved reserves at year-end 2007 were 170.1 BCFE, a seven percent increase over 
2006 year-end proved reserves of 159.5 BCFE.  On a forward looking basis, we expect that proved reserves in this 
area will be booked on 20-acre spacing as the in-fill program at Elm Grove Field continues and additional locations 
become permitted.  We have not however booked these locations as proved reserves at year end due to the Securities 
and Exchange Commission technical requirement of needing to have an “alternate unit” permitting process 
completed prior to booking such items as proved reserves.

The Elm Grove Field is the highest value field in the ArkLaTex region at year-end 2007, with proved 
reserves of 85.3 BCFE and a PV-10 value of $161.3 million.  Elm Grove comprises roughly 42 percent of the 
region’s PV-10 value and approximately four percent of our entire PV-10 value.  We own interests in 382 
producing wells in the field with many of those wells having uphole recompletion potential in the future.  Our 
working interest in the field is as high as 37 percent; higher working interests are located in the southern portion 
of the acreage where recent activity has been occurring.  Reserves in this field are primarily natural gas. 

Our capital budget for the ArkLaTex region in 2008 is $161 million, 51 percent of which will be operated 

by us.  The largest portion of this year’s budget relates to Cotton Valley programs, where 50 percent of the region’s 
capital will be deployed.  Of the capital allocated for Cotton Valley programs, 60 percent will be invested at Elm 
Grove Field where development continues to be highly successful.  Development of the field on 20-acre spacing 
continues to drive activity levels, and a successful horizontal well completed at the end of 2007 could set the stage 
for horizontal development at Elm Grove Field.  The remaining Cotton Valley allocation for 2008 will be split 
roughly evenly between the program at Terryville Field and the St. Mary operated program at Carthage.  Our 
operated horizontal James Lime program will represent 34 percent of the region’s 2008 budget.  We plan to operate 
two drilling rigs throughout the year, with plans to drill more than 20 horizontal James Lime wells in 2008. 

Mid-Continent Region.  St. Mary has been active in the Mid-Continent region since 1973.  Operations for 
the region are managed by our office in Tulsa, Oklahoma.  We have been active in the Anadarko Basin of western 
Oklahoma since our entry into the region and our primary focus in the region is currently on the Atoka and Granite 
Wash formations.  In recent years we have begun operating in the Arkoma Basin in eastern Oklahoma where the 
current focus is on horizontal development of the Woodford shale, although the Wapanucka limestone and 
Cromwell sandstone also appear to have commercial potential.  The Mid-Continent region oversees our assets in 
Constitution South Field in Jefferson County, Texas.  Our long history of operations and proprietary geologic 
knowledge in the region enables us to sustain economic development and exploration programs despite periods of 
adverse industry conditions.  We apply current technology through the use of hydraulic fracturing, innovative well 
completion techniques, and horizontal drilling to accelerate production and associated cash flow from the region’s 
tight gas reservoirs and developing plays. 

In 2007, we invested $185.7 million in the Mid-Continent region on exploration, development, and 

acquisition activity, which is 13 percent less than the $214.3 million deployed in 2006.  Throughout 2007, we 
maintained a consistent level of activity in the Arkoma Basin working on the Woodford shale program as we 
continued to refine our understanding of the play.  We decreased our activity in the Atoka/Granite Wash 
development program as we developed more cost efficient completion designs for these wells.  Mid-Continent 
production in 2007 was 34.0 BCFE, an increase of 14 percent from the 29.8 BCFE produced in 2006.  Proved 
reserves at the end of 2007 were 201.3 BCFE, an increase of 18 percent from the 170.7 BCFE report for the prior 
year. 

The Constitution South Field is the highest value field in the Mid-Continent region with reserves of 

15.2 BCFE and a PV-10 value of $115.1 million.  This field also contributed 8.6 BCFE of production in 2007, 
which represents approximately eight percent of our total production.  Three wells, the Paggi Broussard #1, the 
Paggi Broussard # 2, and the Loretta B. Casey #1, comprise the majority of reserves, PV-10 value, and production 
in the Constitution South Field.  These wells historically have performed better than anticipated and we have a 
history, including at year-end 2007, of recognizing upward performance revisions in our proved reserves at this 
field. 

The 2008 capital expenditure budget for the Mid-Continent region is $135.0 million, 69 percent of which 

we will operate.  The largest component of the budget is our program targeting the Woodford shale using 
horizontal wells in the Arkoma basin, where roughly 30 percent of the region’s budget will be invested.  After 
mixed results in the horizontal Woodford shale program in the first half of 2007, we had a series of successful 
wells in the latter part of the year which we believe validates our understanding of the well and completion design 
being used currently in this program.  Our budget anticipates that we will drill ten horizontal Woodford wells with 
two operated rigs in the first half of 2008, and continue to participate with our partners in outside operated wells.  
With continued success in the play, we have the ability to increase activity and our capital investment in the 
program in the latter part of 2008.  In 2008, we plan to continue with an exploration program in the Anadarko 

6 

Basin that yielded encouraging results in 2007.  This exploration program targets deeper formations of the basin.  
We also plan to deploy approximately 27 percent of the region’s 2008 capital budget to drill six exploratory test 
wells in this program.  In the Western Oklahoma Washes program in the Anadarko Basin, which we have referred 
to previously as the Mayfield development area, we plan to invest roughly 17 percent of the year’s budget in this 
program that targets the Atoka and Granite Wash formations.  The area is a known hydrocarbon province, and 
efforts in 2008 will be directed toward improving the geotechnical effort applied to the program and revising 
drilling and completion techniques. 

Gulf Coast Region.  St. Mary’s presence in south Louisiana dates to the early 1900s when our founders 
acquired our namesake property in St. Mary Parish, Louisiana abutting the Gulf of Mexico.  These 24,914 acres 
of fee lands yielded $3.7 million of gross oil and gas royalty revenue in 2007.  Our Gulf Coast regional presence 
expanded as a result of the acquisition of King Ranch Energy, Inc. in 1999.  During 2007 we reached a significant 
inflection point in this region as it shifted from an office centered on geotechnically driven exploration to one 
focused on repeatable development and exploitation with our acquisition of two Olmos shallow gas assets in 
South Texas.  The Gulf Coast region is run from our office in Houston, Texas. 

Our capital expenditures for exploration, development, and acquisition activity in the Gulf Coast region 

grew significantly from $65.5 million in 2006 to $278.5 million in 2007, primarily driven by two significant 
acquisitions.  The majority of our 94.8 BCFE of acquisitions, classified as purchases of minerals in place, were in 
the Gulf Coast region.  These were the $150.3 million Rockford acquisition that closed in October 2007 and the 
$30.4 million Catarina acquisition which closed in April 2007, both of which target the Olmos shallow gas 
formation and are located in the greater Maverick Basin in Southwestern Texas.  Final year-end reserve estimates 
related to these acquisitions are lower than the initial estimates we previously disclosed, partly due to the fact that 
our presentation of reserves at the time of the acquisition was on a dry gas basis whereas our annual report on 
Form 10-K disclosures utilize a wet gas presentation.  This accounted for approximately ten BCFE of the 
difference in volumes, without any impact to value.  The remaining difference was based on our final year-end 
assessment of proved non-producing reserves and our proved undeveloped reserves, which were each lower than 
the amounts estimated at the time of acquisition.  Our emphasis in 2007 was on the successful integration of our 
newly acquired properties.  While the core focus of the region shifted toward onshore projects, we continued to be 
active offshore in 2007.  A previously discovered intermediate deepwater project, Zloty, began production late in 
2007 and we continue to work to advance other intermediate deepwater projects in which we are a partner.  We 
were also active closer to shore with a mixed program that included the successful Reno, Clement, and Amber 
Jack wells.  Gulf Coast production in 2007 was 10.3 BCFE, an increase of six percent from the 9.7 BCFE 
produced in 2006.  Proved reserves at the end of 2007 were 116.8 BCFE, an increase of 263 percent from the 
32.2 BCFE reported for the prior year.  The disparity between the production growth and reserve growth for the 
Gulf Coast region in 2007 is attributable to the acquisitions previously discussed. 

The most significant asset in the Gulf Coast region is the Gold River project area that was acquired in 

October of 2007 as part of the Rockford acquisition.  The Gold River project area has 104 producing wells as of 
year end.  At December 31, 2007, this project area had a PV-10 value of $136.9 million with 53.6 BCFE of 
proved reserves and accounts for approximately four percent of our entire PV-10 value.  The acquisition of these 
assets, together with the Catarina assets, represents the most recent resource play entry for the Company. 

Our development and exploration budget in the Gulf Coast region for 2008 is $80 million and is focused 

primarily on the development of the Olmos assets acquired in 2007.  St. Mary will operate 75 percent of the 
planned capital investment next year.  Roughly $38 million, or 47 percent, of the budget will be dedicated to grass 
roots Olmos wells and approximately $10 million, or 12 percent, of the budget will be spent on Olmos 
recompletions. 

Permian Basin Region.  The Permian Basin area covers a significant portion of western Texas and eastern 

New Mexico and is one of the major producing basins in the United States.  Our holdings in the Permian Basin 
began with a series of property acquisitions in 1996.  In December 2006, we made a $240.6 million acquisition of 
predominately oil properties in the Sweetie Peck project area.  To manage the significant increase in operated 
properties associated with the Sweetie Peck acquisition, we opened a regional office in Midland, Texas in early 
February 2007. 

7 

In 2007, we spent $135.1 million in the region.  The majority of this capital was deployed to develop 
projects that target the Wolfberry tight oil play, which targets the stacked carbonate Wolfcamp and Spraberry 
formations found in the basin.  We participated in two substantial Wolfberry programs during 2007 – the operated 
Sweetie Peck program and the outside operated program at Halff East.  We operated between two and five drilling 
rigs at Sweetie Peck throughout 2007.  At Halff East, our operating partner had two drilling rigs running throughout 
the year.  We also invested capital in the Parkway and East Shugart Delaware waterflood projects.  Production in the 
region increased 234 percent over the prior year, from 3.2 BCFE in 2006 to 10.7 BCFE in 2007.  Proved reserves as 
of the end of 2007 were 154.7 BCFE, which is an increase of nine percent from 2006 year-end reserves of 
142.2 BCFE. 

As of the end of December 2007, the Sweetie Peck assets in the Permian Basin represented a PV-10 value 

of $438.0 million with 77.7 BCFE of proved reserves.  This accounts for approximately 11 percent of our entire 
PV-10 value.  The Sweetie Peck assets had 106 producing wells and 47 proved undeveloped reserve locations as 
of the end of 2007. 

The capital budget for 2008 in the region is $120 million, of which 74 percent will be operated by us.  Of 

this amount, roughly $103 million, or 86 percent, will be invested in Wolfberry projects.  At Sweetie Peck, we plan 
to spend approximately $77 million operating three drilling rigs continuously throughout the year.  Included in this 
amount are investment dollars to test several 40-acre pilot areas, which if successful could add meaningful proved 
reserves.  At Halff East, we will invest approximately $25 million with our operating partner.  We will also invest a 
small amount of capital in several smaller programs, including our Delaware waterfloods. 

Rocky Mountain Region.  St. Mary has conducted operations in the Williston Basin in eastern Montana 

and western North Dakota since 1991.  The region is managed by our office in Billings, Montana.  In recent years, 
we have expanded our operations into the Greater Green River, Powder River, Big Horn, and Wind River basins 
of Wyoming through a series of acquisitions.  The largest growth in the region came in late 2002 and early 2003 
with significant property acquisitions from Choctaw, Burlington Resources, and Flying J.  These transactions 
brought with them a tremendous acreage position that has precipitated additional growth in this region. 

Including the Hanging Woman Basin coalbed methane project, we invested $178.3 million in 2007 on 

exploration, development, and acquisitions in the Rocky Mountain region, compared to $161.3 million in 2006.  
The 2007 program was focused on a horizontal development in the Mississippian formations of the Williston 
Basin, and the drilling of Bakken formation infill locations in Montana and Red River locations.  Additionally, 
2007 saw an acceleration of drilling at Hanging Woman Basin.  Proved reserves for the Rocky Mountain region 
were 443.6 BCFE at year-end, up five percent from 422.9 BCFE as of year end 2006.  Production in the Rocky 
Mountain region for 2007 was 38.7 BCFE.  Total regional production was down two percent from 39.5 BCFE in 
2006. 

Included in the Rocky Mountain region is the coalbed methane project at Hanging Woman Basin.  This 
program is of particular interest because of the large resource potential on our leasehold.  In 2007, we invested 
$35.7 million at Hanging Woman Basin compared to $30.4 million in 2006. Proved reserves in this project grew 
20 percent in 2007 to 40.2 BCFE, 75 percent of which were proved developed.  Hanging Woman Basin had 
33.4 BCFE in proved reserves at December 31, 2006, 91 percent of which were proved developed.  Production 
was 3.0 BCFE for the year ended 2007, up 49 percent from production in 2006. 

The Elm Coulee Field is the highest value field in the region at year-end 2007, with 92 producing wells 

and proved reserves of 42.4 BCFE and a PV-10 value of $236.5 million.  The reserves in this field are 
predominately oil and the Bakken is the formation of primary interest.  This field comprises approximately 
six percent of our entire PV-10 value. 

Our capital budget for the Rocky Mountain region is $130 million for 2008, with roughly $24 million 

budgeted for activities for Hanging Woman Basin coalbed methane.  We will operate roughly 65 percent of our 
planned regional investment in 2008.  In the conventional Rockies program, several vertical wells and two 
recompletions in the Red River are planned for the year.  We also plan to drill a small number of horizontal 
Bakken wells in and around our historic Bakken development areas in Montana.  Workover and recompletion 

8 

operations are planned in our Wind River Basin and Big Horn Basin oil properties.  At the outside operated 
Atlantic Rim coalbed methane play in the Green River Basin, we expect to see activity ramp up since regulatory 
and environmental delays appear to have been resolved.  At Hanging Woman Basin, we plan to moderate our 
drilling activity in 2008 and monitor and evaluate the results of the shallow and intermediate pods and deep 
horizontal programs from previous year’s drilling efforts. 

Reserves 

The following table presents summary information with respect to the estimates of our proved oil and gas 

reserves for each of the years in the three-year period ended December 31, 2007.  For all years presented 
Netherland, Sewell and Associates, Inc. (“NSAI”) prepared the reserve information for the Company’s coalbed 
natural gas projects at Hanging Woman Basin in the northern Powder River Basin and St. Mary’s non-operated 
coalbed methane interest in the Green River Basin.  We engaged Ryder Scott Company, L.P. to review internal 
engineering estimates for 80 percent of the PV-10 value of our proven conventional oil and gas reserves in 2007 and 
2006.  In 2005, Ryder Scott Company, L.P. prepared the reserve estimates for at least 80 percent of the PV-10 value 
of our conventional oil and gas assets.  St. Mary personnel prepared the reserve estimates for the remainder of all 
properties.  The Company emphasizes that reserve estimates are inherently imprecise and that estimates of new 
discoveries and undeveloped locations are more imprecise than estimates of established producing oil and gas 
properties.  Accordingly, these estimates are expected to change as future information becomes available.  The PV-
10 values shown in the following table are not intended to represent the current market value of the estimated 
proved oil and gas reserves owned by St. Mary.  Neither prices nor costs have been escalated.  You should read 
the following table along with the section entitled “Risk Factors – Risks Related to Our Business – The actual 
quantities and present values of our proved oil and natural gas reserves may be less than we have estimated.”  No 
estimates of our proved reserves have been filed with or included in reports to any federal authority or agency, 
other than the Securities and Exchange Commission, since the beginning of the last fiscal year.

Productive Wells 

As of December 31, 2007, St. Mary had working interests in 2,365 gross (1,125 net) productive oil wells 
and 4,199 gross (1,405 net) productive gas wells.  Productive wells are either producing wells or wells capable of 
commercial production although currently shut-in.  One or more completions in the same wellbore are counted as 
one well.  A well is categorized under state reporting regulations as an oil well or a gas well based upon the ratio of 
gas to oil produced when it first commenced production, and such designation may not be indicative of current 
production. 

Drilling Activity 

All of our drilling activities are conducted on a contract basis with independent drilling contractors.  We do 
not own any drilling equipment.  The following table sets forth the wells drilled and recompleted in which St. Mary 
participated during each of the three years indicated:

(1)  Developed acreage is acreage assigned to producing wells for the spacing unit of the producing formation.  

Developed acreage in certain of St. Mary's properties that include multiple formations with different well 
spacing requirements may be considered undeveloped for certain formations, but have only been included as 
developed acreage in the presentation above.  

(2)  Undeveloped acreage is lease acreage on which wells have not been drilled or completed to a point that would 
permit the production of commercial quantities of oil and gas, regardless of whether such acreage contains 
estimated proved reserves. 

(3)  St. Mary holds an overriding royalty interest in an additional 36,021 gross acres in Utah. 
(4)  Includes interests in Alabama, Kansas, Nebraska and South Dakota. 
(5)  Subsequent to December 31, 2007, St. Mary divested certain non-core properties, which included leases 
covering approximately 155,400 and 53,900 developed gross and net acres, respectively, and 67,100 and 
38,400 undeveloped gross and net acres, respectively.  Additionally, St. Mary also divested its overriding 
royalty interest in 36,000 gross acres in Utah. 

Major Customers 

During 2007 and 2006, no customer individually accounted for ten percent or more of the Company’s total 

oil and gas production revenue.  During 2005, sales to Tesoro Refining and Marketing individually accounted for 
13 percent of the Company’s total oil and gas production revenue. 

Employees and Office Space 

As of February 15, 2008, we had 438 full-time employees.  None of our employees are subject to a 

collective bargaining agreement, and we consider our relations with our employees to be good.  We lease 
approximately 77,000 square feet of office space in Denver, Colorado for our executive and administrative 

12 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
offices, of which approximately 10,000 square feet is subleased.  We lease approximately 22,000 square feet of 
office space in Tulsa, Oklahoma; approximately 21,000 square feet in Shreveport, Louisiana; approximately 
20,000 square feet in Houston, Texas; approximately 12,000 square feet in Midland, Texas; approximately 36,000 
square feet in Billings, Montana; and approximately 2,000 square feet in Casper, Wyoming. 

Title to Properties 

Substantially all of our working interests are held pursuant to leases from third parties.  A title opinion is 

usually obtained prior to the commencement of drilling operations.  We have obtained title opinions or have 
conducted a thorough title review on substantially all of our producing properties and believe that we have 
satisfactory title to such properties in accordance with standards generally accepted in the oil and gas industry.  The 
majority of the value of our properties is subject to a mortgage under our credit facility, customary royalty interests, 
liens for current taxes, and other burdens that we believe do not materially interfere with the use of or affect the 
value of such properties.  We perform only a minimal title investigation before acquiring undeveloped leasehold. 

Seasonality 

Generally, but not always, the demand and price levels for natural gas increase during the colder winter 

months and decrease during the warmer summer months.  To lessen seasonal demand fluctuations, pipelines, 
utilities, local distribution companies, and industrial users utilize natural gas storage facilities and forward 
purchase some of their anticipated winter requirements during the summer.  However, increased summertime 
demand for electricity is beginning to place an increasing demand on storage volumes.  Crude oil and the demand 
for heating oil are also impacted by generally higher prices in the winter – although oil is much more driven by 
global supply and demand.  Seasonal anomalies such as mild winters sometimes lessen these fluctuations.  The 
impact of seasonality has somewhat been exacerbated by the overall supply and demand economics related to 
crude oil because there is a narrow margin of production capacity in excess of existing worldwide demand. 

Competition 

The oil and gas industry is intensely competitive.  This is particularly true in the competition for acquisitions 

of prospective oil and natural gas properties and oil and gas reserves.  We believe that our leasehold position 
provides a sound foundation for a solid drilling program.  Our competitive position also depends on our geological, 
geophysical, and engineering expertise, and our financial resources.  We believe that the location of our leasehold 
acreage, our exploration, drilling, and production expertise, and the experience and knowledge of our management 
and industry partners enable us to compete effectively in our core operating areas.  Notwithstanding our talents and 
assets, we still face stiff competition from a substantial number of major and independent oil and gas companies that 
have larger technical staffs and greater financial and operational resources than we do.  Many of these companies not 
only engage in the acquisition, exploration, development, and production of oil and natural gas reserves, but also 
have refining operations, market refined products, own drilling rigs, and generate electricity.  We also compete with 
other oil and natural gas companies in attempting to secure drilling rigs and other equipment necessary for the 
drilling and completion of wells.  Consequently, drilling equipment may be in short supply from time to time.  
Currently, access to incremental drilling equipment in certain regions is difficult but is not, at this time, anticipated 
to have any material negative impact on our ability to deploy our drilling capital budget for 2008.  We are seeing 
signs of loosening rig availability, although it is quite specific by region.  Finally, we also compete for people.  
Throughout the industry, the need for talented people has grown at a time when the number of people available is 
constrained.  We are not insulated from this resource constraint and we have to be willing to compete in this market 
in order to be successful. 

Government Regulations 

Our business is subject to various federal, state, and local laws and governmental regulations that may be 

changed from time to time in response to economic or political conditions.  Matters subject to regulation include the 
issuance of drilling permits, discharge permits for drilling operations, drilling bonds, reports concerning operations, 
the spacing of wells, unitization and pooling of properties, taxation, and environmental protection.  From time to 

13 

time, regulatory agencies have imposed price controls and limitations on production by restricting the rate of flow of 
oil and gas wells below actual production capacity in order to conserve supplies of oil and gas. 

Energy Regulations.  Our sale of natural gas is affected by the availability, terms, and cost of transportation.  

The price and terms of access to pipeline transportation are subject to extensive federal and state regulation.  While 
the rules and regulations of the Federal Energy Regulatory Commission (FERC) have in the past greatly affected the 
production and sale of natural gas, the direct impact on the upstream exploration and production segment of the 
energy industry has changed to allow market forces to set the price paid for natural gas.  FERC regulations continue 
to affect the midstream and transportation segments of the industry and thus can have an indirect impact of the sales 
price we receive for natural gas production.  There is no assurance that the less stringent regulatory approach 
recently pursued by the FERC and Congress will continue.  We do not believe that we will be more materially 
affected by any action taken by the FERC or Congress than other natural gas producers and marketers with whom 
we compete. 

Certain operations we conduct involve federal minerals administered by the Minerals Management 
Service (MMS).  The MMS issues leases covering such lands through competitive bidding.  These leases contain 
relatively standardized terms and require compliance with federal laws and detailed MMS regulations.  For 
offshore operations, lessees must obtain MMS approval for exploration plans and development and production 
plans prior to the commencement of such operations.  In addition to permits required from other agencies such as 
the Coast Guard, the Army Corps of Engineers, and the Environmental Protection Agency, lessees must obtain a 
permit from the MMS prior to the commencement of drilling.  Lessees must also comply with detailed MMS 
regulations governing, among other things: 

•  Engineering and construction specifications for offshore production facilities 

•  Safety procedures 

•  Flaring of production 

•  Plugging and abandonment of Outer Continental Shelf (OCS) wells 

•  Calculation of royalty payments and the valuation of production for this purpose 

•  Removal of facilities. 

To cover the various obligations of lessees on the OCS, the MMS generally requires that lessees post 
substantial bonds or other acceptable assurances that such obligations will be met.  The cost of such bonds or 
other surety can be substantial, and we may not be able to continue to obtain bonds or other surety in all cases.  
Under certain circumstances the MMS may require our operations on federal leases to be suspended or 
terminated. 

Many of the states in which we conduct our oil and gas drilling and production activities regulate such 
activities by requiring, among other things, drilling permits and bonds and reports concerning operations.  The 
laws of these states also govern a number of environmental and conservation matters, including the handling and 
disposing of waste material, plugging and abandonment of wells, restoration requirements, unitization, pooling of 
interests in natural gas and oil properties, and establishment of maximum rates of production from natural gas and 
oil wells.  States generally have the ability to prorate production to the market demand for oil and natural gas; 
however, this is not currently occurring. 

Environmental Regulations.  Our operations are subject to numerous existing federal, state, and local laws 

and regulations governing environmental quality and pollution control.  These laws and regulations may require that 
permits be obtained before drilling commences, restrict the types, quantities, and concentration of various substances 
that can be released into the environment in connection with drilling and production activities, and limit or prohibit 
drilling activities on certain lands lying within wilderness, wetlands, and other protected areas, including areas 
containing endangered animal species.  As a result, these laws and regulations may substantially increase the costs of 

14 

exploring for, developing, or producing oil and gas and may prevent or delay the commencement or continuation of 
certain projects.  In addition, these laws and regulations may impose substantial clean-up, remediation, and other 
obligations in the event of any discharges or emissions in violation of such laws and regulations. 

Our coalbed methane gas production is similar to our traditional natural gas production as to the physical 
producing facilities and the product produced.  However, the subsurface mechanisms that allow the gas to move 
to the wellbore and the producing characteristics of coalbed methane wells are very different from traditional 
natural gas production.  Unlike conventional gas wells, which require a porous and permeable reservoir, 
hydrocarbon migration, and a natural structural and/or stratigraphic trap, coalbed methane gas is trapped in the 
molecular structure of the coal itself until released by pressure changes resulting from the removal of in situ 
water.  Frequently, coalbeds are partly or completely saturated with water.  As the water is removed, internal 
pressures on the coal are decreased, allowing the gas to desorb from the coal and flow to the wellbore.  Unlike 
traditional gas wells, new coalbed methane wells often produce water for several months and then, as the water 
production decreases, natural gas production increases. 

Coalbed methane gas production requires state permits for the use of well-site pits and evaporation ponds 
for the disposal of produced water.  Groundwater produced from the coal seams can generally be discharged into 
arroyos, surface waters, well-site pits, and evaporation ponds without a permit if it does not exceed surface 
discharge permit levels, and meets state and federal primary drinking water standards.  All of these disposal 
options require an extensive third-party water sampling and laboratory analysis program to ensure compliance 
with state permit standards.  Where water of lesser quality is involved or the wells produce water in excess of the 
applicable volumetric permit limits, additional disposal wells may have to be drilled to re-inject the produced 
water back into underground rock formations. 

A portion of our acreage at the Hanging Woman Basin coalbed methane project is on federal lands in 

Montana.  We are subject to delays in permitting associated with the completion of a supplemental Environmental 
Impact Statement covering the contemplation of phased development on federal leases in Montana.  We are also 
affected by considerations for sage grouse that are native to the area.  Each of these issues has the potential to 
impact the timing of our permitting and drilling operations associated with development of Hanging Woman 
Basin. 

To date we have not experienced any material adverse effect on our operations from obligations under 

environmental laws and regulations.  We believe that we are in substantial compliance with currently applicable 
environmental laws and regulations and that continued compliance with existing requirements would not have a 
material adverse impact on us.

giving effect to non-property related expenses such as general and administrative expenses, debt service and future 
income tax expenses or to depreciation, depletion, and amortization, discounted using an annual discount rate of 
ten percent.  While this measure does not include the effect of income taxes as it would in the use of the standardized 
measure calculation, it does provide an indicative representation of the relative value of the Company on a 
comparative basis to other companies and from period to period. 

Productive well.  A well that is producing oil or natural gas or that is capable of commercial production. 

Proved developed reserves.  Reserves that can be expected to be recovered through existing wells with existing 
equipment and operating methods. 

Proved reserves.  The estimated quantities of oil, natural gas, and natural gas liquids which geological and 
engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs 
under existing economic and operating conditions. 

Proved undeveloped reserves.  Reserves that are expected to be recovered from new wells on undrilled acreage or 
from existing wells where a relatively major expenditure is required for recompletion. 

Recompletion.  The completion in an existing wellbore in a formation other than that in which the well has 
previously been completed.

the relative success a company is having in replacing its production from its declining asset base as well as its ability 
to grow the overall company. 

Reserve replacement percentage – including sales of reserves.  The sum of sales of reserves, reserve extensions and 
discoveries, reserve acquisitions, and reserve revisions of previous estimates for a specified period of time divided 
by production for that same period of time.  This is believed to be a useful non-GAAP measure that is widely 
utilized within the exploration and production industry as well as by investors.  It is an easily calculable number and 
is representative of the relative success a company is having in replacing its production from its declining asset base 
as well as its ability to grow the overall company. 

Royalty.  The amount or fee paid to the owner of mineral rights, expressed as a percentage of gross income from oil 
and natural gas produced and sold unencumbered by expenses relating to the drilling, completing, and operating of

production free of costs of exploration, development, and production operations. 

19 

Standardized measure of discounted future net cash flows.  The discounted future net cash flows relating to proved 
reserves based on year-end prices, costs, and statutory tax rates, and a ten percent annual discount rate.  The 
information for this calculation is included in the note regarding disclosures about oil and gas producing activities 
contained in the Notes to Consolidated Financial Statements included in this Form 10-K. 

Undeveloped acreage.  Lease acreage on which wells have not been drilled or completed to a point that would 
permit the production of commercial quantities of oil and natural gas, regardless of whether such acreage contains 
estimated net proved reserves. 

Working interest.  The operating interest that gives the owner the right to drill, produce, and conduct operating 
activities on the property and to share in the production, sales, and costs.

In  addition  to  the  other  information  included  in  this  Form 10-K,  the  following  risk  factors  should  be 

carefully considered when evaluating St. Mary. 

Risks Related to Our Business 

Oil and natural gas prices are volatile and a decline in prices could hurt our profitability, financial condition, cash 
flows, access to capital, and ability to grow. 

Our revenues, operating results, profitability, future rate of growth, and the carrying value of our oil and 

natural gas properties depend heavily on the prices we receive for oil and natural gas sales.  Oil and natural gas 
prices also affect our cash flows and borrowing capacity, as well as the amount and value of our oil and natural 
gas reserves. 

Historically, the markets for oil and natural gas have been volatile and they are likely to continue to be 

volatile.  Wide fluctuations in oil and natural gas prices may result from relatively minor changes in the supply of 
and demand for oil and natural gas, market uncertainty, and other factors that are beyond our control, including: 

•  Worldwide and domestic supplies of oil and natural gas 

•  The ability of the members of the Organization of Petroleum Exporting Countries to agree to and 

maintain oil price and production controls 

•  Pipeline, transportation, or refining capacity constraints in a regional or localized area may impact the 

realized price for oil or natural gas 

•  Political instability or armed conflict in oil or natural gas producing regions 

•  The price and level of foreign imports of crude oil, refined petroleum products, and liquefied natural 

gas 

•  Worldwide and domestic economic conditions 

•  The level of consumer demand for hydrocarbons 

•  Productive capacity of the industry as a whole 

•  The availability of transportation facilities 

•  Weather conditions 

20 

•  The price and availability of alternative fuels 

•  Governmental regulations and taxes. 

These factors and the volatility of oil and natural gas markets make it very difficult to predict future oil 

and natural gas price movements with any certainty.  Declines in oil or natural gas prices would reduce our 
revenues and could also reduce the amount of oil and natural gas that we can produce economically, which could 
have a material adverse effect on us. 

If we are not able to replace reserves, we will not be able to sustain production. 

Our future operations depend on our ability to find, develop, and acquire oil and natural gas reserves that 

are economically recoverable.  Our properties produce oil and natural gas at a declining rate over time.  In order to 
maintain current production rates we must locate and develop or acquire new oil and natural gas reserves to 
replace those being depleted by production.  In addition, competition for the acquisition of producing oil and 
natural gas properties is intense and many of our competitors have financial and other resources needed to 
evaluate and integrate acquisitions that are substantially greater than those available to us.  Therefore, we may not 
be able to acquire oil and natural gas properties that contain economically recoverable reserves, or we may not be 
able to acquire such properties at prices acceptable to us.  Without successful drilling or acquisition activities, our 
reserves, production, and revenues will decline over time. 

Competition in our industry is intense, and many of our competitors have greater financial, technical and human 
resources than we do. 

We face intense competition from major oil companies, independent oil and natural gas exploration and 

production companies, financial buyers, and institutional and individual investors who are actively seeking oil and 
natural gas properties throughout the world, as well as the equipment, expertise, labor, and materials required to 
operate oil and natural gas properties.  Many of our competitors have financial and technical resources vastly 
exceeding those available to us, and many oil and natural gas properties are sold in a competitive bidding process in 
which our competitors may be able or willing to pay more for development prospects and productive properties or in 
which our competitors have technological information or expertise that is not available to us to evaluate and 
successfully bid for the properties.  In addition, shortages of equipment, labor, or materials as a result of intense 
competition may result in increased costs or the inability to obtain those resources as needed.  We may not be 
successful in acquiring and developing profitable properties in the face of this competition. 

We also compete for people.  The need for talented people across all disciplines in the industry has grown at 

a time when the number of people available is constrained. 

The actual quantities and present values of our proved oil and natural gas reserves may be less than we have 
estimated. 

This Form 10-K and other SEC filings by us contain estimates of our proved oil and natural gas reserves 
and the estimated future net revenues from those reserves.  Reserve estimates are based on various assumptions, 
including assumptions required by the SEC relating to oil and natural gas prices, drilling and operating expenses, 
capital expenditures, taxes, timing of operations, and availability of funds.  The process of estimating reserves is 
complex.  This process requires significant decisions and assumptions in the evaluation of available geological, 
geophysical, engineering, and economic data for each reservoir.  These estimates are dependent on many variables 
and therefore changes often occur as these variables evolve.  Therefore, these estimates are inherently imprecise. 

Actual future production, oil and natural gas prices, revenues, production taxes, development 

expenditures, operating expenses, and quantities of recoverable oil and natural gas reserves will most likely vary 
from those estimated.  Any significant variance could materially affect the estimated quantities of and present 
values related to proved reserves disclosed by us, and the actual quantities and present values may be less than we 
have previously estimated.  In addition, we may adjust estimates of proved reserves to reflect production history, 
results of exploration and development activity, prevailing oil and natural gas prices, costs to develop and operate 

21 

properties, and other factors, many of which are beyond our control.  Our properties may also be susceptible to 
hydrocarbon drainage from production by operators on adjacent properties. 

As of December 31, 2007, approximately 23 percent, or 250.2 BCFE, of our estimated proved reserves 

were proved undeveloped and approximately 11 percent or 116.0 BCFE, were proved developed non-producing.  
Estimates of proved undeveloped reserves and proved developed non-producing reserves are nearly always based 
on volumetric calculations rather than the performance data used to estimate producing reserves.  In order to 
recover our proved undeveloped reserves, an estimated $234 million of capital expenditures will be spent during 
2008.  Production revenues from proved developed non-producing reserves will not be realized until some time in 
the future.  In order to bring production on-line for our proved developed non-producing reserves, we estimate 
capital expenditures of $12 million for 2008.  Although we have estimated our reserves and the costs associated 
with these reserves in accordance with industry standards, estimated costs may not be accurate, development may 
not occur as scheduled and actual results may not occur as estimated.  The balance of our capital expenditure 
budget for 2008 is directed towards projects that are not yet classified within the construct of proved reserves as 
defined by Regulation S-X of the Securities and Exchange Commission. 

You should not assume that the PV-10 value and standardized measure of discounted future net cash 

flows included in this Form 10-K represent the current market value of our estimated proved oil and natural gas 
reserves.  Management has based the estimated discounted future net cash flows from proved reserves on prices 
and costs as of the date of the estimate, in accordance with SEC requirements, whereas actual future prices and 
costs may be materially higher or lower.  For example, values of our reserves as of December 31, 2007, were 
estimated using a calculated sales price of $6.80 per MMBtu of natural gas (NYMEX Henry Hub spot price) and 
$95.98 per Bbl of oil (NYMEX West Texas Intermediate spot price).  We then adjust this base price to ensure we 
consider the appropriate basis and location differentials as of that date in estimating our proved reserves.  During 
2007, our monthly average realized natural gas prices, excluding the effect of hedging, were as high as $7.83 per 
Mcf and as low as $5.42 per Mcf.  For the same period our monthly average realized oil prices before hedging 
were as high as $91.53 per Bbl and as low as $48.88 per Bbl.  Many other factors will affect actual future net cash 
flows, including: 

•  Amount and timing of actual production 

•  Supply and demand for oil and natural gas 

•  Curtailments or increases in consumption by oil purchasers and natural gas pipelines 

•  Changes in governmental regulations or taxes. 

The timing of production from oil and natural gas properties and of related expenses affects the timing of 

actual future net cash flows from proved reserves and thus their actual present value.  Our actual future net cash 
flows could be less than the estimated future net cash flows for purposes of computing PV-10 values.  In addition, 
the ten percent discount factor required by the SEC to be used to calculate PV-10 values for reporting purposes is 
not necessarily the most appropriate discount factor given actual interest rates and risks to which our business and 
the oil and natural gas industry in general are subject. 

Our producing property acquisitions may not be worth what we paid due to uncertainties in evaluating recoverable 
reserves and other expected benefits, as well as potential liabilities. 

Successful property acquisitions require an assessment of a number of factors beyond our control.  These 

factors include exploration potential, future oil and natural gas prices, operating costs, and potential 
environmental and other liabilities.  These assessments are not precise and their accuracy is inherently uncertain. 

In connection with our acquisitions, we perform a customary review of the acquired properties that will 
not necessarily reveal all existing or potential problems.  In addition, our review may not allow us to fully assess 
the potential deficiencies of the properties.  We do not inspect every well, and even when we inspect a well we 
may not discover structural, subsurface, or environmental problems that may exist or arise.  We may not be 

22 

entitled to contractual indemnification for pre-closing liabilities, including environmental liabilities.  Normally, 
we acquire interests in properties on an “as is” basis with limited remedies for breaches of representations and 
warranties. 

In addition, significant acquisitions can change the nature of our operations and business if the acquired 

properties have substantially different operating and geological characteristics or are in different geographic 
locations than our existing properties.  To the extent acquired properties are substantially different than our 
existing properties, our ability to efficiently realize the expected economic benefits of such acquisitions may be 
limited. 

Integrating acquired properties and businesses involves a number of other special risks, including the risk 

that management may be distracted from normal business concerns by the need to integrate operations and 
systems as well as retain and assimilate additional employees.  Therefore, we may not be able to realize all of the 
anticipated benefits of our acquisitions. 

Exploration and development drilling may not result in commercially productive reserves. 

Oil and natural gas drilling and production activities are subject to numerous risks, including the risk that 

no commercially productive oil or natural gas will be found.  The cost of drilling and completing wells is often 
uncertain, and oil and natural gas drilling and production activities may be shortened, delayed, or canceled as a 
result of a variety of factors, many of which are beyond our control.  These factors include: 

•  Unexpected drilling conditions 

•  Title problems 

•  Pressure or geologic irregularities in formations 

•  Equipment failures or accidents 

•  Hurricanes and other adverse weather conditions 

•  Compliance with environmental and other governmental requirements 

•  Shortages or delays in the availability of or increases in the cost of drilling rigs and crews, fracture 

stimulation crews and equipment, chemicals, and supplies. 

The prevailing prices of oil and natural gas affect the cost of and the demand for drilling rigs, production 

equipment, and related services.  The availability of drilling rigs can vary significantly from region to region at 
any particular time.  Although land drilling rigs can be moved from one region to another in response to changes 
in levels of demand, an undersupply of rigs in any region may result in drilling delays and higher drilling costs for 
the rigs that are available in that region. 

Another significant risk inherent in our drilling plans is the need to obtain drilling permits from state, 

local, and other governmental authorities.  Delays in obtaining regulatory approvals and drilling permits, 
including delays which jeopardize our ability to realize the potential benefits from leased properties within the 
applicable lease periods, the failure to obtain a drilling permit for a well, or the receipt of a permit with 
unreasonable conditions or costs could have a materially adverse effect on our ability to explore on or develop our 
properties. 

The wells we drill may not be productive and we may not recover all or any portion of our investment in 
such wells.  The seismic data and other technologies we use do not allow us to know conclusively prior to drilling 
a well if oil or natural gas is present, or whether it can be produced economically.  The cost of drilling, 
completing, and operating a well is often uncertain, and cost factors can adversely affect the economics of a 

23 

project.  Drilling activities can result in dry holes or wells that are productive but do not produce sufficient net 
revenues after operating and other costs to cover initial drilling and completion costs. 

Our future drilling activities may not be successful.  Our overall drilling success rate or our drilling 
success rate for activity within a particular area may decline.  In addition, we may not be able to obtain any 
options or lease rights in potential drilling locations that we identify.  Although we have identified numerous 
potential drilling locations, we may not be able to economically produce oil or natural gas from all of them. 

Our hedging transactions may limit the prices that we receive for oil and natural gas sales and involve other risks. 

To manage our exposure to price risks in the sale of our oil and natural gas, we enter into commodity price 
risk management arrangements periodically with respect to a portion of our current or future production.  We have 
hedged a significant portion of anticipated future production from our currently producing properties using zero-cost 
collars and swaps.  Commodity price hedging may limit the prices that we receive for our oil and natural gas sales if 
oil or natural gas prices rise substantially over the price established by the hedge.  In addition, these transactions may 
expose us to the risk of financial loss in certain circumstances, including instances in which: 

•  Our production is less than expected 

•  There is a widening of price differentials between delivery points for our production and the delivery 

point assumed in the hedge arrangement 

•  The counterparties to our hedge contracts fail to perform under the contracts. 

Some of our hedging agreements may also require us to furnish cash collateral, letters of credit, or other 
forms of performance assurance in the event that mark-to-market calculations result in settlement obligations by 
us to the counterparties, which could impact our liquidity and capital resources.  In addition, some of our hedging 
transactions use derivative instruments that may involve basis risk.  Basis risk in a hedging contract occurs when 
the index upon which the contract is based is more or less variable than the index upon which the hedged asset is 
based, thereby making the hedge less effective.  For example, a NYMEX index used for hedging certain volumes 
of production may have more or less variability than the regional price index used for the sale of that production. 

Future oil and natural gas price declines or unsuccessful exploration efforts may result in write-downs of our 
asset carrying values. 

We follow the successful efforts method of accounting for our oil and natural gas properties.  All property 

acquisition costs and costs of exploratory and development wells are capitalized when incurred, pending the 
determination of whether proved reserves have been discovered.  If proved reserves are not discovered with an 
exploratory well, the costs of drilling the well are expensed. 

The capitalized costs of our oil and natural gas properties, on a field basis, cannot exceed the estimated 

undiscounted future net cash flows of that field.  If net capitalized costs exceed future net revenues, we must write 
down the costs of each such field to our estimate of its fair market value.  Unproved properties are evaluated at the 
lower of cost or fair market value.  Accordingly, a significant decline in oil or natural gas prices or unsuccessful 
exploration efforts could cause a future write-down of capitalized costs. 

We review the carrying value of our properties quarterly based on prices in effect as of the end of each 
quarter or as of the time of reporting our results.  Once incurred, a write-down of oil and natural gas properties 
cannot be reversed at a later date even if oil or natural gas prices increase. 

Substantial capital is required to replace our reserves. 

We need to make substantial capital expenditures to find, acquire, develop, and produce oil and natural 
gas reserves.  Future cash flows and the availability of financing are subject to a number of factors, such as the 
level of production from existing wells, our success in locating and acquiring new reserves, and prices paid for oil 

24 

and natural gas.  If oil or natural gas prices decrease or we encounter operating difficulties that result in our cash 
flows from operations being less than expected, we may have to reduce our capital expenditures unless we can 
raise additional funds through debt or equity financing or the divestment of assets.  Debt or equity financing may 
not always be available to us in sufficient amounts or on acceptable terms.  The proceeds offered to us for 
potential divestitures may not always be of acceptable value to us. 

If our revenues were to decrease due to lower oil or natural gas prices, decreased production, or other 

reasons, and if we could not obtain capital through our revolving credit facility, other acceptable debt or equity 
financing arrangements, or sale of non-core assets, our ability to execute our development plans, replace our 
reserves, or maintain production levels could be greatly limited. 

The markets for raising public debt are quite constrained at the current time, given the overall liquidity 
concerns arising from the widely reported difficulties in the sub-prime and leveraged loan markets.  While we 
continue to believe that our secured revolving credit facility will be sufficient for the foreseeable future, we must 
continually monitor the overall condition of the markets as a whole and remain cognizant that an overall pressure 
on the credit markets has the risk of increasing the cost of borrowings or decreasing the availability of new capital 
or the capacity of existing debt instruments. 

A decrease in oil or natural gas prices could limit our ability to borrow under our revolving credit facility. 

Our revolving credit facility currently has a maximum commitment amount of $500 million, subject to a 

borrowing base of $1.25 billion that the lenders periodically redetermine based on the bank groups’ assessment of 
the value of our oil and natural gas properties, which in turn is based in part on oil and natural gas prices.  Lower 
oil or natural gas prices in the future could limit our borrowing base and reduce our ability to borrow under the 
credit facility. 

Our amount of debt may limit our ability to obtain financing for acquisitions, make us more vulnerable to adverse 
economic conditions, and make it more difficult for us to make payments on our debt. 

As of December 31, 2007, we had $287.5 million of total long-term senior unsecured debt outstanding 
under our 3.50 % Senior Convertible Notes due 2027 and $285.0 million of secured debt outstanding under our 
revolving credit facility.  As of February 15, 2008, we had an outstanding balance of $180.0 million drawn against 
our revolving credit facility resulting in $320.0 million of available debt capacity under our revolving credit facility, 
assuming the borrowing conditions of this facility were met.  Our long-term debt represented 40 percent of our total 
book capitalization as of December 31, 2007.  The decrease in the borrowings subsequent to year end is a result of 
using the net proceeds from the sale of non-core properties on January 31, 2008.  Our revolving credit facility has a 
maximum loan amount of $500 million, a current borrowing base of $1.25 billion, and we have elected a current 
commitment amount of $500 million. 

Our amount of debt could have important consequences for our operations, including: 

•  Making it more difficult for us to obtain additional financing in the future for our operations and 
potential acquisitions, working capital requirements, capital expenditures, debt service, or other 
general corporate requirements 

•  Requiring us to dedicate a substantial portion of our cash flows from operations to the repayment of 
our debt and the service of interest associated with our debt rather than to productive investments. 

•  Limiting our operating flexibility due to financial and other restrictive covenants, including 

restrictions on incurring additional debt, creating liens on our properties, making acquisitions, and 
paying dividends 

25 

•  Placing us at a competitive disadvantage compared to our competitors that have less debt 

•  Making us more vulnerable in the event of adverse economic or industry conditions or a downturn in 

our business. 

Our ability to make payments on our debt and to refinance our debt and fund planned capital expenditures 

will depend on our ability to generate cash in the future.  This, to a certain extent, is subject to general economic, 
financial, competitive, legislative, regulatory, and other factors that are beyond our control.  If our business does 
not generate sufficient cash flow from operations or future sufficient borrowings are not available to us under our 
revolving credit facility or from other sources we might not be able to service our debt or to fund our other 
liquidity needs.  If we are unable to service our debt, due to inadequate liquidity or otherwise, we may have to 
delay or cancel acquisitions, sell equity securities, sell assets, or restructure or refinance our debt.  We might not 
be able to sell our equity securities, sell our assets or restructure or refinance our debt on a timely basis or on 
satisfactory terms or at all.  In addition, the terms of our existing or future debt agreements, including our existing 
and future credit agreements, may prohibit us from pursuing any of these alternatives. 

Our debt instruments, including our revolving credit agreement, also permit us to incur additional debt in 

the future.  In addition, the entities we may acquire in the future could have significant amounts of debt 
outstanding which we could be required to assume in connection with the acquisition, or we may incur our own 
significant indebtedness to consummate an acquisition. 

In addition, our revolving credit facility is subject to periodic borrowing base redeterminations.  We could 
be forced to repay a portion of our bank borrowings in the event of a downward redetermination of our borrowing 
base, and we may not have sufficient funds to make such repayment at that time.  If we do not have sufficient 
funds and are otherwise unable to negotiate renewals of our borrowing base or arrange new financing, we may be 
forced to sell significant assets. 

We are subject to operating and environmental risks and hazards that could result in substantial losses. 

Oil and natural gas operations are subject to many risks, including well blowouts, craterings, explosions, 
uncontrollable flows of oil, natural gas or well fluids, fires, adverse weather such as hurricanes in the Gulf Coast 
region, freezing conditions, formations with abnormal pressures, pipeline ruptures or spills, pollution, releases of 
toxic gas, and other environmental risks and hazards.  If any of these types of events occurs, we could sustain 
substantial losses. 

Under certain limited circumstances we may be liable for environmental damage caused by previous owners 

or operators of properties that we own, lease, or operate.  As a result, we may incur substantial liabilities to third 
parties or governmental entities, which could reduce or eliminate funds available for exploration, development, or 
acquisitions or cause us to incur losses. 

We maintain insurance against some, but not all, of these potential risks and losses.  We have significant 

but limited coverage for sudden environmental damages.  We do not believe that insurance coverage for the full 
potential liability that could be caused by sudden environmental damages or insurance coverage for environmental 
damage that occurs over time is available at a reasonable cost.  In addition, pollution and environmental risks 
generally are not fully insurable.  Further, we may elect not to obtain other insurance coverage under 
circumstances where we believe that the cost of available insurance is excessive relative to the risks presented.  
Accordingly, we may be subject to liability or may lose substantial portions of certain properties in the event of 
environmental or other damages.  If a significant accident or other event occurs and is not fully covered by 
insurance, we could suffer a material loss. 

Following the severe Atlantic hurricanes in 2004 and 2005, the insurance markets suffered significant 

losses.  As a result, the availability of coverage and the cost at which such coverage will be available in the future is 
uncertain, and such coverage has become substantially more expensive. 

26 

Our operations are subject to complex laws and regulations, including environmental regulations that result in 
substantial costs and other risks. 

Federal, state, and local authorities extensively regulate the oil and natural gas industry.  Legislation and 

regulations affecting the industry are under constant review for amendment or expansion, raising the possibility of 
changes that may affect, among other things, the pricing or marketing of oil and natural gas production.  
Noncompliance with statutes and regulations may lead to substantial penalties, and the overall regulatory burden on 
the industry increases the cost of doing business and, in turn, decreases profitability. 

Governmental authorities regulate various aspects of oil and natural gas drilling and production, including 
the drilling of wells (through permit and bonding requirements), the spacing of wells, the unitization or pooling of 
interests in oil and natural gas properties, environmental matters, safety standards, the sharing of markets, production 
limitations, plugging and abandonment standards, and restoration.  To cover the various obligations of leaseholders 
in federal waters, federal authorities generally require that leaseholders have substantial net worth or post bonds or 
other acceptable assurances that such obligations will be met.  The cost of these bonds or other assurances can be 
substantial, and we may not be able to obtain bonds or other assurances in all cases.  Under limited circumstances, 
federal authorities may require any of our ongoing or planned operations on federal leases to be delayed, suspended 
or terminated.  Any such delay, suspension or termination could have a material adverse effect on our operations.  
Our coalbed methane development at Hanging Woman Basin is particularly affected, as a portion of our acreage is 
on federal lands in Montana which have been subject to delays in permitting. 

Our operations are also subject to complex and constantly changing environmental laws and regulations 

adopted by federal, state, and local governmental authorities in jurisdictions where we are engaged in exploration or 
production operations.  New laws or regulations, or changes to current requirements, could result in material costs or 
claims with respect to properties we own or have owned.  We will continue to be subject to uncertainty associated 
with new regulatory interpretations and inconsistent interpretations between state and federal agencies.  Under 
existing or future environmental laws and regulations, we could face significant liability to governmental authorities 
and third parties, including joint and several as well as strict liability, for discharges of oil, natural gas, or other 
pollutants into the air, soil, or water, and we could be required to spend substantial amounts on investigations, 
litigation, and remediation.  Existing environmental laws or regulations, as currently interpreted or enforced, or as 
they may be interpreted, enforced, or altered in the future, may have a materially adverse effect on us. 

In addition, recent studies have suggested that emissions of certain gases, commonly referred to as 
“greenhouse gases,” may be contributing to warming of the Earth’s atmosphere.  Methane, a primary component 
of natural gas, and carbon dioxide, a byproduct of the burning of refined oil products and natural gas, are 
examples of greenhouse gases.  In response to these studies, the U.S. Congress is considering legislation to reduce 
emissions of greenhouse gases.  In addition, at least nine states in the Northeast and five states in the West have 
separately taken legal measures to reduce emissions of greenhouse gases, primarily through the planned 
development of greenhouse gas emissions inventories and/or regional greenhouse gas cap and trade programs.  
Also, as a result of the U.S. Supreme Court’s decision on April 2, 2007 in Massachusetts et al. v. Environmental 
Protection Agency et al., the U.S. Environmental Protection Agency must reconsider whether it is required to 
regulate greenhouse gas emissions from motor vehicles even if Congress does not adopt new legislation 
specifically addressing emissions of greenhouse gases.  The Court’s holding in Massachusetts that greenhouse 
gases fall under the Federal Clean Air Act’s definition of “air pollutant” may also result in future regulation of 
greenhouse gas emissions from stationary sources under certain Clean Air Act programs.  Passage of climate 
change legislation or other regulatory initiatives by Congress or various states or the adoption of regulations by 
the EPA or analogous state agencies that restrict emissions of greenhouse gases, including methane or carbon 
dioxide, in areas in which we conduct business could adversely affect our operations and the demand for our 
products. 

We depend on transportation facilities owned by others. 

The marketability of our oil and natural gas production depends in part on the availability, proximity, and 

capacity of pipeline transportation systems owned by third parties.  The lack of available transportation capacity on 
these systems and facilities could result in the shutting-in of producing wells, the delay or discontinuance of 

27 

development plans for properties, or lower price realizations.  Although we have some contractual control over the 
transportation of our production, material changes in these business relationships could materially affect our 
operations.  Federal and state regulation of oil and natural gas production and transportation, tax and energy policies, 
changes in supply and demand, pipeline pressures, damage to or destruction of pipelines, and general economic 
conditions could adversely affect our ability to produce, gather, and transport oil and natural gas. 

Risks Related to Our Common Stock 

The price of our common stock may fluctuate significantly, which may result in losses for investors. 

From January 1, 2007 to February 15, 2008, the closing daily sales price of our common stock as reported 
by the New York Stock Exchange ranged from a low of $31.80 per share to a high of $44.07 per share.  We expect 
our stock to continue to be subject to fluctuations as a result of a variety of factors, including factors beyond our 
control.  These factors include: 

•  Changes in oil or natural gas prices 

•  Variations in quarterly drilling, recompletions, acquisitions, and operating results 

•  Changes in financial estimates by securities analysts 

•  Changes in market valuations of comparable companies 

•  Additions or departures of key personnel 

•  Future sales of our common stock 

•  Changes in the national and global economic outlook. 

We  may  fail  to  meet  expectations  of  our  stockholders  and/or  of  securities  analysts  at  some  time  in  the 

future, and our stock price could decline as a result. 

Our certificate of incorporation and bylaws have provisions that discourage corporate takeovers and could prevent 
stockholders from receiving a takeover premium on their investment. 

Our certificate of incorporation and bylaws contain provisions that may have the effect of delaying or 

preventing a change of control.  These provisions, among other things, provide for non-cumulative voting in the 
election of the Board of Directors and impose procedural requirements on stockholders who wish to make 
nominations for the election of Directors or propose other actions at stockholder meetings.  These provisions, 
alone or in combination with each other and with the shareholder rights plan described below, may discourage 
transactions involving actual or potential changes of control, including transactions that otherwise could involve 
payment of a premium over prevailing market prices to stockholders for their common stock. 

Under our shareholder rights plan, if the Board of Directors determines that the terms of a potential 

acquisition do not reflect the long-term value of St. Mary, the Board of Directors could allow the holder of each 
outstanding share of our common stock other than those held by the potential acquirer to purchase one additional 
share of our common stock with a market value of twice the exercise price.  This prospective dilution to a 
potential acquirer would make the acquisition impracticable unless the terms were improved to the satisfaction of 
the Board of Directors.  The existence of the plan may impede a takeover not supported by our Board even though 
such takeover may be desired by a majority of our stockholders or may involve a premium over the prevailing 
stock price. 

28 

Shares eligible for future sale may cause the market price of our common stock to drop significantly, even if our 
business is doing well. 

The potential for sales of substantial amounts of our common stock in the public market may have a 
material adverse effect on our stock price.  As of February 15, 2008, 62,915,531 shares of our common stock 
were freely tradable without substantial restriction or the requirement of future registration under the Securities 
Act of 1933.  Also as of that date, options to purchase 2,367,914 shares of our common stock were outstanding, of 
which 2,360,414 were exercisable.  These options are exercisable at prices ranging from $4.63 to $20.87 per 
share.  In addition, restricted stock units providing for the issuance of up to a total of 682,446 shares of our 
common stock were outstanding.  As of February 15, 2008, there were 63,020,524 shares of common stock 
outstanding, which is net of 1,009,712 treasury shares. 

We may not always pay dividends on our common stock. 

The payment of future dividends remains in the discretion of the Board of Directors and will continue to 
depend on our earnings, capital requirements, financial condition, and other factors.  In addition, the payment of 
dividends is subject to covenants in our credit facility, including a covenant regarding the level of our current ratio 
of current assets to current liabilities and a limit on the annual dividend rate that we may pay to no more than 
$0.25 per share.  The Board of Directors may determine in the future to reduce the current semi-annual dividend 
rate of $0.05 per share or discontinue the payment of dividends altogether.

not “filed” with the Securities and Exchange Commission. 

Holders.  As of February 15, 2008, the number of record holders of St. Mary's common stock was 116.  

Based on inquiry, management believes that the number of beneficial owners of our common stock is approximately 
21,700. 

Dividends.  St. Mary has paid cash dividends to stockholders every year since 1940.  Semi-annual dividends 

of $0.025 per share were paid in each of the years 1998 through 2004.  Semi-annual dividends of $0.05 per share 
were paid in 2005, 2006 and 2007.  We expect that our practice of paying dividends on our common stock will 
continue, although the payment of future dividends will continue to depend on our earnings, capital requirements, 
financial condition, and other factors.  In addition, the payment of dividends is subject to covenants in our credit 
facility, including the requirement that we maintain certain levels of stockholders’ equity and the limitation of our 
annual dividend rate to no more than $0.25 per share per year.  Dividends are currently paid on a semi-annual basis.  
Dividends paid totaled $6.3 million in 2007. 

Restricted Shares.  Aside from Rule 144 restrictions on shares for insiders, shares subject to transfer 
restrictions under the provisions of the Employee Stock Purchase Plan, restricted shares issued to directors under the 
Non-Employee Director Stock Compensation Plan, and restricted shares issued to directors under the 2006 Equity 
Incentive Compensation Plan (the “2006 Equity Plan”), St. Mary has no restricted shares outstanding as of 
December 31, 2007.

Equity Compensation Plans.  St. Mary has the 2006 Equity Plan under which options and shares of

(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, 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.  Awards granted in 2007, 2006, 
and 2005 under the 2006 Equity Plan and the Predecessor Plans were 135,138, 527,678, and 209,238, respectively. 

(2)  Under the St. Mary Land & Exploration Company Employee Stock Purchase Plan, 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 Employee Stock Purchase Plan are restricted for 
a period of 18 months from the date issued.  The Employee Stock Purchase Plan is intended to qualify under Section 
423 of the Internal Revenue Code.  There have been 29,534, 26,046, and 28,447 shares issued under this plan in 
2007, 2006, and 2005, respectively.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
RESULTS OF OPERATIONS 

This discussion includes forward-looking statements.  Please refer to “Cautionary Information about 
Forward-Looking Statements” in Part I, Items 1 and 2 of this Form 10-K for important information about these types 
of statements. 

Overview of the Company 

General Overview 

We are an independent energy company focused on the development, exploration, exploitation, 
acquisition, and production of natural gas and crude oil in the United States.  We earn 95 percent of our revenues 
and generate our cash flows from operations primarily from the sale of produced natural gas and crude oil.  Our 
oil and gas reserves and operations are concentrated primarily in various Rocky Mountain basins, including the 
Williston, Big Horn, Wind River, Powder River and Greater Green River basins; the Mid-Continent Anadarko 
and Arkoma basins; the Permian Basin; the tight sandstone reservoirs of East Texas and North Louisiana; South 
Texas assets targeting the Olmos shallow gas formation; and the onshore Gulf Coast and offshore Gulf of Mexico.  
We have developed a balanced and diverse portfolio of proved reserves, development drilling opportunities, and 
unconventional resource prospects. 

In 2007, we achieved the following financial and operational results: 

•  Average daily gas production of 181.0 MMcf per day, up 17 percent from 2006.  Average daily 
oil production of 18.9 MBbl per day, up 14 percent from 2006.  Average total equivalent daily 
production was 294.5 MMCFE which was an annual record for the Company. 

•  Estimated proved reserves of 78.8 MMBbls of oil and 613.5 Bcf of natural gas, or 1,086.5 BCFE, 

as of December 31, 2007.  This was an increase of 17 percent from year-end 2006 proved 
reserves of 927.6 BCFE. 

•  Diluted earnings per share for 2007 were $2.94 on net income of $189.7 million.  This reflects a 

slight decrease in net income when compared to 2006.  The earnings per share benefited from the 
0.8 million shares acquired by the Company during 2007.   

•  Cash flow from operating activities of $630.8 million, an increase of 35 percent from 2006. 

•  Debt to capitalization ratio is 40 percent.  The 2007 amount does not consider proceeds from our 
divestiture of non-core assets that closed on January 31, 2008, described in Note 3 of Part IV, 
Item 15 of this report, which were used to pay down outstanding bank borrowings. 

Our business objective is to economically grow our production and proved reserves through development, 
exploitation, and exploration activities, as well as through acquisitions of developed and undeveloped properties.  
Our operations are generally funded first through cash flows from operating activities, and then borrowings under 
our existing credit facility.  Acquisitions may be funded with proceeds from sales of public or private debt and 
equity, borrowings under our existing credit facility, and cash flow from operating activities.  In 2007, we 
deployed $740.9 million for development and exploration and invested $185.2 million for acquisitions of oil and 
gas properties. 

A major determinant of the value of our Company is the value of our proved reserves.  At year-end 2007, 
we had proved reserves of 1,086.5 BCFE of which 56 percent were natural gas and 77 percent were characterized 
as proved developed.  Based on our year-end oil and gas reserve estimation process, we determined that we added 
94.8 BCFE of proved reserves through acquisitions in 2007, 96 percent of which was natural gas and 42 percent 
of which was proved developed.  Upward price revisions resulted in an increase of 34.5 BCFE which were driven 
primarily by higher oil prices at December 31, 2007, compared to the prior year.  We experienced positive 

38 

performance revisions of 6.4 BCFE and divested 1.4 BCFE of proved reserves.  The before income tax PV-10 
value of our proved reserves was $3.9 billion as of December 31, 2007.  The after tax value of $2.7 billion as 
represented by the standardized measure calculation is presented in Note 13 of Part IV, Item 15 of this report.  A 
reconciliation between these two amounts is shown under Reserves in Part I, Items 1 and 2 of this report.  This 
value is based on adjusted year-end pricing of $7.56 per Mcf and $88.71 per Bbl, which are up 36 percent and 
65 percent, respectively, from the prior year. 

Chief Executive Officer, Chief Financial Officer and Senior and Regional Management Transitions 

During 2007, the Company underwent or announced personnel changes in the chief executive position and 

several regional manager positions.  On February 23, 2007, Mark Hellerstein, retired as Chief Executive Officer 
after serving in that role since 1995.  Tony Best, President of the Company, was appointed as Chief Executive 
Officer on that date.  Mr. Hellerstein continues to serve as the Chairman of the Board.  In June 2007, Jerry Schuyler, 
the Senior Vice President responsible for the Gulf Coast and Permian regions, left St. Mary to pursue other 
professional opportunities.  Greg Leyendecker, then Operations Manager for the Gulf Coast region, assumed 
responsibility for the Gulf Coast and is now Vice President - Regional Manager of the Gulf Coast region.  We also 
made the Midland office a stand-alone regional office which is headed by Lehman Newton III, as Vce President - 
Regional Manager of the Permian region.  Mr. Leyendecker and Mr. Newton both joined St. Mary in 2006 and each 
have over 25 years of management and operational experience in the oil and gas industry.  In July 2007, 
Stephen Pugh joined the Company as Senior Vice President - Regional Manager of the ArkLaTex region.  Mr. Pugh 
succeeded David Hart, who retired from St. Mary after 15 years in various roles at the Company.  Mr. Pugh came to 
St. Mary with over 25 years of engineering, operations, and business development experience in the oil and gas 
industry.  In August of this year, Robert Nance, Senior Vice President - Regional Manager of the Rocky Mountain 
region announced his decision to retire in the first quarter of 2008 after more than 40 years in the oil and gas 
industry.  Mark Mueller joined the Company as Senior Vice President in September and is now responsible for the 
Rocky Mountain region.  Mr. Mueller has 20 years of management and technical experience in the oil and gas 
industry.  Effective January 1, 2008, Mark Mueller became the Senior Vice President and Regional Manager.  
Subsequent to year end, David Honeyfield, Senior Vice President - Chief Financial Officer, announced he will 
resign effective March 21, 2008, to accept an executive position in an unrelated industry. 

2007 Acquisition of South Texas Oil and Natural Gas Assets 

We entered the greater Maverick Basin with two acquisitions in South Texas that target the Olmos shallow 
gas formation.  These two acquisitions comprised the majority of the 94.8 BCFE of reserves classified as purchases 
of minerals in place.  These properties added a sizable inventory of lower risk drilling locations to our portfolio.  The 
first was the $30.0 million Catarina acquisition that closed in June 2007, in which we acquired 14.0 BCFE of proved 
reserves that were 99 percent gas and 65 percent proved developed.  The average working interest in these assets is 
30 percent; however we are the operator of the project area.  The more significant transaction was the $148.9 million 
Rockford acquisition that closed in October 2007, where we have a nearly 100 percent working interest and are the 
operator.  As mentioned elsewhere in this report, the final year-end reserve estimates we recorded were lower than 
the initial estimates we previously disclosed at the time of acquisition.  We initially estimated reserves on a dry 
gas basis in our previous disclosure at the time of the acquisition whereas our annual report on Form 10-K 
disclosures utilize a wet gas presentation convention.  This accounted for approximately ten BCFE of the 
difference in volumes, without any impact on value.  The remaining difference was a result of our final year end 
assessment of proved non-producing reserves and our proved undeveloped reserves which were each lower than 
the amounts preliminarily estimated at the time of acquisition.  The Rockford properties are adjacent to the 
Catarina assets.  Consistent with prior acquisitions, we hedged several years of risked production related to these 
assets at the time of acquisition.  These assets will be managed by our Gulf Coast region based in Houston, Texas.   

2007 Capital Markets Activity 

In March of 2007 we called for redemption of the then outstanding $100.0 million 5.75% Senior 

Convertible Notes.  The notes had a conversion price of $13.00 per share.  One hundred percent of the holders of the 
notes elected to convert their notes into shares of common stock.  As a result of the conversion, 7.7 million shares of 
stock were issued to the note holders.  This resulted in a decrease to long-term debt of $100.0 million, and an 

39 

increase to common stock associated with the conversion together with the recognition of the excess tax benefit 
associated with the contingent interest feature associated with the notes.  In April of 2007, we completed the private 
placement of $287.5 million of 3.50% Senior Convertible Notes.  The net proceeds from the 3.50% Senior 
Convertible Notes were used to repay outstanding borrowings under our revolving credit facility. 

Reserve Replacement, Finding Costs and Growth 

Like all oil and gas exploration and production companies, we face the challenge of natural production 

declines of oil and natural gas resources.  An oil and gas exploration and production company depletes part of its 
asset base with each unit of oil and gas it produces.  Historically, we have been able to grow our production 
despite this natural decline by adding more reserves through acquisitions and drilling activities than we produce.  
Future growth will depend on our ability to economically continue adding reserves in excess of production.  

We believe growth in net asset value per share drives appreciation in our stock price over the long term.  

Our challenge is to grow net asset value per share.  To accomplish this, our goal is to economically replace at least 
200 percent of annual production with new reserves and to grow production by ten to 15 percent per year. In 
2007, we replaced 248 percent of our production at a finding cost of $3.48 per MCFE.  The reserve replacement 
percentages and finding cost terms are defined in the glossary at the end of Part I, Items 1 and 2 of this report.  
Excluding acquisitions, we replaced 161 percent of our production at a cost of $4.42 per MCFE.  Through 
acquisition activities we replaced 88 percent of production at an acquisition cost of $1.71 per MCFE.  We sold 
reserves representing 1.4 BCFE of our proved reserves during 2007.  We believe annual reserve replacement 
percentage and finding cost amounts are important analytical measures that are widely used by investors and 
industry peers in evaluating and comparing the performance of oil and gas companies.  While single year 
measurements have some meaning in terms of a trend, we believe that evaluating these items over an extended 
period of time is a better indication of performance.  We note that aberrations, causing both relatively good and 
bad results, will occur over short intervals of time.  Our three-year average reserve replacement ratio – including 
sales is 249 percent and our three-year average all-in finding cost is $3.01 per MCFE.  Our finding cost numbers, 
particularly those related to drilling activities, have been notably higher in recent years.  Part of this is explained 
by increases in completed well costs that have occurred in recent years which have affected all exploration and 
production companies.  A significant part has related to the performance of our capital investments being less than 
anticipated.  We will need to see an improvement in the types of projects we are pursuing and/or see an 
improvement in our operating abilities to meaningfully bring our finding cost numbers down.  We believe that we 
have taken steps through recent acquisitions and portfolio screenings to improve the projects in which we are 
investing.  Our operating teams are also performing technological reviews to see where we can improve our 
operations. 

Sustainability in our business is dependent on the ability to create new ideas and new value year-after-

year.  The challenges we face are increasingly more difficult each year as North American oil and gas production 
continues to decline and other exploration and production companies compete for available reserves.  We believe 
we have a formula for meeting these challenges.  We have placed talented geoscientists, engineers, and landmen 
in each of our regional offices where their experience and knowledge of the local area can be fully utilized.  We 
provide a compensation package that aligns their goals with those of the Company and in turn with those of our 
stockholders.  We support our personnel with a strong balance sheet and fiscal and operating discipline.  Even so, 
we are subject to similar constraints as other companies in the exploration and production industry.  Limitations to 
future growth will be based on overall availability of additional qualified personnel and the generation of new 
ideas and the utilization of appropriate technology to improve the economics of our operations.  We believe that 
we have sufficient capital resources for the foreseeable future, that we have the ability to grow our workforce, and 
that we have the necessary access to drilling rigs and services to execute our drilling budget for 2008 in a 
successful and profitable manner. 

Oil and Gas Prices 

Results of our operations and financial condition are significantly affected by oil and natural gas 
commodity prices, which fluctuate dramatically.  In 2007, we saw a net increase in oil prices throughout the year.  
Geopolitical unrest in various producing regions overseas and concerns domestically related to refinery utilization 

40 

and petroleum product inventories were the principal drivers of the increase in oil prices in 2007.  Natural gas 
prices were moderated throughout 2007 by high levels of natural gas in storage and a lack of significant disruptive 
hurricane activity during year. 

Repurchase of Common Stock 

We evaluate the market price of our common stock relative to our internal assessment of net asset value 

per share.  To the extent that the market price per share is below what we believe to be the net asset value per 
share and when the trading window for the Company and executive management is open, we may repurchase 
shares under the program.  In 2007, we repurchased 792,216 shares of our common stock in the open market for a 
weighted-average price of $32.76 per share, including commissions.  These shares were purchased under a share 
repurchase program approved by the Board.  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 our shares were trading.  As of the date of this filing, we are authorized to repurchase an 
additional 5,207,784 million shares under this program. 

Hedging Activities   

We have an active hedging program in which we hedge the first two to five years of an acquisition’s 

risked production.  We will also on occasion enter into derivative transactions to hedge a portion of our existing 
forecasted production.  In October 2005, we hedged a significant portion of anticipated future production from 
our current producing properties using zero-cost collars.  We also hedged a portion of specific forecasted natural 
gas production for 2006, 2007, and 2008 using swap contracts.  Taking into account all oil and gas production 
hedge contracts in place through February 15, 2008, we have hedged anticipated future production of 
approximately 11 million Bbls of oil, 70 million MMBtu of natural gas, and 1 million Bbls of natural gas liquids 
through the year 2011.  We believe we have established an economic base for our future operations, and the 
spread between the price floors and ceilings on our collars allows us to continue to participate in a higher oil and 
gas price environment.  Please see Note 10 of Part IV, Item 15 of this report for additional information regarding 
our oil and gas hedges, and see the caption, Summary of Oil and Gas Production Hedges in Place, later in this 
section. 

Net Profits Plan   

Payments made for distributions from the Net Profits Plan have been expensed as compensation costs in 
the amounts of $31.9 million, $26.1 million, and $20.8 million for the years ended December 31, 2007, 2006, and 
2005, respectively.  Although increasing each year, these payments for 2007 were lower than originally budgeted 
due to the effects of increased oil and gas production expense and additional capital expenditures, both of which 
decreased the current impact of and delayed the timing of payout for the 2004 pool.  The actual cash payments we 
make are dependent on actual production, realized prices, and operating and capital costs associated with the 
properties in each individual pool.  Actual cash payments will be inherently different from the estimated liability 
amounts.  More detailed discussion is included in the analysis in the Comparison of Financial Results and Trends 
sections below.  An increasing percentage of the costs associated with the payments for the Net Profits Plan are 
attributable to general and administrative expense as compared to exploration expense.  This is a function of the 
normal departure of employees who previously contributed to our past exploration efforts.  We have determined that 
because of the change in circumstances, a greater percentage of the payments should be recorded as general and 
administrative expense beginning in 2007. 

With respect to the accounting estimate of the liability associated with future estimated payments from 

our Net Profits Plan, we have recorded $50.8 million of net expense for the year ended December 31, 2007, 
thereby increasing the long-term liability associated with this item.  This increase is related to an increase in the 
estimated future prices used to calculate the liability driven by overall commodity price increases, the accretion of 
the discount used for the calculation, and the addition of the 2007 pool.  Additionally, we adjusted our discount 
rate used to calculate the present value of future payments during the fourth quarter of 2007 from a base rate of 
15 percent to 12 percent.  The single largest item was the impact from the change in discount rate, which drove an 
increase in the liability of $29 million as of December 31, 2007.  As a result of these factors the liability increased 

41 

to $211.4 million at December 31, 2007.  While we have forecast that this liability will again increase in 2008, it 
is not possible to predict this with certainty due to the impact of commodity prices and reserve estimates on the 
valuation of this estimated liability.  The Company will not be adding new Net Profits Plan pools prospectively as 
this benefit has been replaced with a different program, which is described in Footnote 7 of Part IV, Item 15 of 
this Form 10-K.  The Company will continue to make payments from the established Net Profits Plan pools, as 
well as make prospective adjustments to the long-term liability, as necessary for current conditions.  We expect 
general and administrative expense to increase due to changes in our incentive compensation program.  Beginning 
in 2008, grants from the restricted stock units program and the Net Profits Plan are being replaced with grants of 
market-based performance shares under our 2006 Equity Plan.  Although the total value of the compensation 
package to employees is essentially unchanged, we do expect general and administrative expense to increase as 
the cost of the grants of performance shares under the 2006 Equity Plan will be amortized over a much shorter 
time than the functional expense recorded under the Net Profits Plan. 

The calculation of the estimated liability associated with the Net Profits Plan requires management to 

prepare an estimate of future amounts payable from the Net Profits Plan.  On a monthly basis, we calculate 
estimates of the payments to be made for each individual pool.  The underlying principal factors for our estimates 
are forecasted oil and gas production from the properties that comprise each individual pool, price assumptions, 
cost assumptions, and discount rate.  In most cases, the cash flow streams used in these calculations will span 
more than 20 years.  The decrease in the discount rate to 12 percent was a result of the ever increasing competitive 
environment for proven oil and gas properties and our assessment of the overall market for proved oil and gas 
reserves.  Commodity prices impact the calculated cash flows during periods after payout and can dramatically 
affect the timing of the estimated date of payout of the individual pools.  Our commodity price assumptions are 
currently determined from an average of actual prices realized over the prior 24 months together with adjusted 
NYMEX strip prices for the ensuing 12 months for a total of 36 months of data.  This average is supplemented by 
including the effect of realized and anticipated hedge prices for the percentage of forecasted hedged production in 
the relevant period. 

The calculation of the estimated liability for the Net Profits Plan is highly sensitive to our price estimates 

and discount rate assumptions. For example, if we changed the commodity prices in our calculation by 
five percent, the liability recorded on the balance sheet at December 31, 2007, would differ by approximately 
$19 million.  A one percentage point decrease in the discount rate would result in an increase to the liability of 
approximately $12 million, while a one percentage point increase in the discount rate would result in a decrease to 
the liability of approximately $10 million.  We frequently re-evaluate the assumptions used in our calculations 
and consider the possible impacts stemming from the current market environment including current and future oil 
and gas prices, discount rates, and overall market conditions.

*As a result of a change in circumstances in 2007, we have begun classifying payments made under the Net Profits Plan to 
exploration overhead only for those individuals who are currently employed by us and who continue to be involved in our 
exploration efforts.  Therefore, the quarterly financial information presented in the above table reflects that Net Profits Plan 
payments associated with the distributions under the Net Profits Plan for ex-employees were recorded to general and 
administrative expense since there is no longer any functional link to exploration expense as there is by definition no periodic 
costs associated with geologic and geophysical, exploration related work by those ex-employees.  The impact to any prior 
comparative quarter was not material. 

2007 Financial Highlights 

In 2007, we experienced record production and strong earnings.  Our record production is the realization 

of operational and investment decisions made in prior years as well as the current period.  Our solid earnings 
reflect our balanced production profile and high oil prices throughout the year.  Our hedging program contributed 
to our earnings as we received meaningful cash flows from the realization of in-the-money natural gas hedges.  
Our operating margins remained strong in 2007 despite increasing operating costs.  Our 2007 operating margin 
was $6.68 per MCFE compared to $6.27 per MCFE in 2006.   

Net income for 2007 was $189.7 million or $2.94 per diluted share compared to $190.0 million or 
$2.94 per diluted share for the prior year.  Net cash provided by operating activities was $630.8 million, up 
35 percent from 2006.  Average daily production for the year increased 16 percent to a record 294.5 MMCFE.  
Our average net realized price increased $0.53 to $8.71 per MCFE.  Unit costs increased for the period as lease 
operating expenses increased $0.06 to $1.31 per MCFE.  While general industry costs associated with drilling and 
completing wells are flat or declining year over year, costs related to the ongoing operation of oil and gas

properties continue to experience upward pressure.  This increase over last year’s comparable period is driven by 
continued pressure on costs related to the servicing of wells, such as disposal and trucking, as well as workover 
and labor costs.  As a company with a significant oil component to our production mix, our property base 
inherently requires more labor than operations that are dominated by natural gas production.  Labor costs continue 
to be a significant driver of our lease operating expense.  In addition to the higher costs we are incurring on our 
base activity, we also have been actively incurring workover expense to restore or increase production in the Gulf 
Coast and Rocky Mountain regions.  Per MCFE transportation costs increased $0.02 per MCFE, or 17 percent, to 
$0.14 per MCFE as compared to a year ago.  The increase is due to newly drilled wells with higher transportation 
costs.  Production taxes increased $0.04 per MCFE to $0.58 per MCFE and are a reflection of higher commodity 
prices. 

Depletion, depreciation, and amortization, including asset retirement obligation accretion expense, per 

MCFE increased $0.45 to $2.12 per MCFE.  The depletion, depreciation, and amortization increase is reflective of 
higher costs on a per MCFE basis for new reserve additions relative to the base per MCFE cost of oil and gas 
properties.  General and administrative expense increased $0.14 per MCFE to $0.56 per MCFE.  The increase in 
general and administrative expenses is driven by our growing employee base and higher payments from the Net 
Profits Plan.  Exploration expense for 2007 was $58.7 million, which was $6.8 million higher than the 
$51.9 million incurred during 2006 due to an increase in exploratory dry hole expense as well as the overall 
increase in the level of exploration activity during 2007.  We discuss these financial results and trends in more 
detail below. 

Outlook for 2008 

Our anticipated exploration and development drilling budget is $626 million for 2008, which is 

16 percent smaller than the $740.9 million we spent on development and exploration in 2007.  The decrease in our 
development and exploration budget reflects our desire to improve the capital efficiency of our investments and to 
manage the balance sheet to improve financial flexibility in the future.  Planned expenditures for programs that 
failed to meet our expectations in 2007 were either omitted or substantially reduced in 2008.  The reduced budget 
for 2008 is also expected to allow for cash flow in excess of our capital investments for the year.  We believe that 
this will provide us the financial flexibility to accelerate successful drilling programs, pursue potential acquisition 
opportunities, repurchase outstanding shares of common stock, or repay bank borrowings when the opportunity 
arises.  We have not budgeted any capital for acquisitions in 2008, however we believe our solid financial 
condition provides us the ability to execute significant transactions we believe will be accretive to the Company.  
We anticipate production for the first half of 2008 to be slightly lower than the last quarter of 2007 due to the 
divestiture of non-core properties that closed subsequent to year-end.  We project production will ramp up in the 
second half of 2008 as many of our exploration and development projects are scheduled to come on-line in the 
second half of the year. 

Our 2008 capital budget was built using a NYMEX price deck of $7.00 per Mcf and $60.00 per barrel.  
Current strip prices for oil and natural gas support our plans for the year.  However, we are keenly aware of how 
volatile oil and natural gas prices are and how quickly they can move.  The cost environment related to drilling 
and completing wells appears to have leveled out in the past year after several years of significant cost escalation.  
Day rates for land-based drilling rigs have held flat or declined throughout the year, and the increasing number of 
drilling rigs entering the market bodes well for this trend.  Prices for completion services continue to be firm, but 
we note new capacity is being added by incumbent providers as well as new entrants to the service sector.  
Availability of drilling and completion services is not the potentially limiting condition that existed the last two 
years.  Prices for these services are highly dynamic, vary greatly region to region, and are influenced greatly by 
commodity prices.  We will continue to evaluate the economics of each well prior to the onset of drilling using the 
most current commodity price and cost information available to ensure it meets our economic and operational 
thresholds.

The information below provides some detail of our capital investment plans for 2008: 

•  We believe that we have the necessary capital, personnel, and service availability to execute this 

program.  The $626 million budgeted for drilling activities in 2008 is allocated among our core areas 
as described below.  Included in the discussion are highlights of the program in each region this year. 

ArkLaTex - $161 million – Half of our budgeted capital investment for this region in 2008 is for 
projects targeting the Cotton Valley sandstone formation.  The largest component relates to activity 
planned at Elm Grove Field, where 20-acre increased density drilling and Hosston and Cotton Valley 
formation commingling are improving results and enhancing reserve recovery.  Importantly, there has 
been a successful horizontal test well at Elm Grove Field that could lead to additional upside.  Also in 
the Cotton Valley program, we plan to participate in twice the number of wells in Terryville Field in 
2008 compared to 2007.  Lastly, we will operate a small Cotton Valley program in 2008 where we 
have plans to drill two vertical and three horizontal wells.  The other major program in the ArkLaTex 
region is our operated horizontal James Lime program.  We plan to operate two drilling rigs 
continuously and drill more than 20 wells throughout 2008. 

Mid-Continent - $135 million – The largest part of our 2008 program in the Mid-Continent relates to 
the horizontal Woodford program in the Arkoma Basin.  After mixed results in the horizontal 
Woodford program in the first half of 2007, we had a series of successful wells in the latter part of the 
year which we believe validates our understanding of the well and completion design.  We currently 
plan to drill ten horizontal Woodford wells using two operated rigs in the first half of 2008, as well as 
continuing to participate with our partners in outside operated wells.  With continued success in the 
play, we anticipate increasing our activity and our capital investment in the program in the latter part 
of 2008.  In the Western Oklahoma Washes program in the Anadarko Basin, which we have referred 
to previously as the Mayfield development area, we plan to invest in projects in the Atoka and 
Granite Wash formations.  The area is a known hydrocarbon province, and efforts in 2008 will center 
around refining our assessments of geotechnical aspects of the program and revising drilling and 
completion techniques with an intent to lower the completion costs.  We also plan to deploy 
approximately one quarter of the region’s 2008 capital budget to drill six exploratory test wells which 
focus on a geologic concept that was developed in 2007 which targets deeper formations in the 
Anadarko Basin. 

Rocky Mountain  - $130 million –  In the conventional Rockies program, six vertical wells and two 
recompletions in the Red River are planned for 2008.  We also plan to drill a small number of 
horizontal Bakken wells in and around our historic Bakken development areas in Montana.  We have 
planned workover and recompletion operations in our Wind River Basin and Big Horn Basin oil 
properties.  At the outside operated Atlantic Rim coalbed methane play in the Green River Basin, we 
expect to see activity ramp up since regulatory and environmental delays appear to have been 
resolved.  At Hanging Woman Basin, we plan to moderate our drilling activity in 2008 focusing on 
completing the in-fill program in the shallow coals, monitoring the intermediate depth wells and 
testing several horizontal completion techniques in the deeper coal horizontal programs. 

Permian - $120 million – The vast majority of capital investment made in the Permian in 2008 will be 
in properties targeting the Wolfberry section.  At Sweetie Peck, we plan to operate three drilling rigs 
continuously throughout the year.  Included in the budget are investment dollars to test several 40-acre 
pilot areas which, if successful, could add meaningful proved reserves.  At the Halff East Wolfberry 
development area, we will invest approximately $25 million with our operating partner.  We will also be 
investing a small amount of capital in several smaller programs, including the Delaware waterfloods. 

Gulf Coast - $80 million – Our development and exploration budget in the Gulf Coast region for 2008 
is focused on the integration and development of the two Olmos shallow gas projects that we acquired 
in South Texas in 2007.  Approximately half of the budgeted capital will be deployed to drill new 

45 

 
Olmos wells, with additional capital being invested in a number of recompletion opportunities.  We 
anticipate that the addition of this resource play will provide focus and a visible inventory of projects 
for our Gulf Coast team.  We will also invest capital in production facilities for an intermediate 
deepwater discovery from 2005 that is expected to be brought online in early 2009.

The increase in our proved reserves reflects our drilling results and acquisition activity.  Please see Note 13 
of Part IV, Item 15 for additional details.  Over time, our ability to economically replace at least 200 percent of the 
total volumes produced annually has proven to be a key factor that determines whether we are successful in 
achieving our goal of increasing net asset value per share.  We anticipate that we must continue our successful 
drilling program and average one or more relatively significant acquisitions per year in the current price environment 
to achieve this level of ongoing growth.  The measure of our success will vary year-to-year due to changes in these 
factors. 

Rapid changes in production volumes, oil and gas sales revenues, and costs reflect the cyclical and highly 

volatile prices our industry receives for production, as well as the impact of the timing of acquisitions.  The 
comparison of changes in production from 2006 to 2007 reflects the positive results from our drilling programs in 
2007 and the full year impact of a significant acquisition made in the fourth quarter of 2006.  Production volumes in 
2007 were also affected by production from oil and gas properties acquired in 2007 and from production from new 
drilling activity. 

We present per MCFE information because we use this information to evaluate our performance relative to 

our peers and to identify and measure trends that we believe require analysis.  Our year-to-year comparison of 
financial results presented later provides additional details for the analysis of changes between years in selected line 
items.  Oil and gas production expenses increased in 2007 as a result of a higher percentage of oil production and 
ongoing upward pressure for oil and gas sector services related to the ongoing operation of our oil and gas 
properties.  Depreciation, depletion, and amortization will continue to significantly increase due to higher costs 
associated with finding and acquiring crude oil and natural gas reserves.  General and administrative expense 
increased as a result of $41 million in expense associated with payments under our Net Profits Plan, costs associated 
with office space and overall upward pressure on compensation in the exploration and production industry. 

We have in-the-money stock options, unvested restricted stock units, and Senior Convertible Notes that are 

considered potentially dilutive securities.  At times these dilutive securities can affect our earnings per share.  
Consequently, both basic and diluted earnings per share are presented in the table above.  A detailed explanation is 
presented in Note 1 of Part IV, Item 15 of this report.  Basic and diluted weighted-average common shares 
outstanding used in our 2007, 2006 and 2005 earnings per share calculations reflect our stock repurchases, offset by 
an increase in outstanding shares related to stock option exercises.  Basic and diluted weighted-average shares 
outstanding in 2007 were affected by similar factors as 2006 and 2005, as well as an increase in shares that is related 
to the issuance of common stock upon settlement of RSU’s following the expiration of the restriction period.  We 
issued 733,650 shares of common stock in 2007, 1,489,636 shares in 2006, and 936,403 shares in 2005 as a result of 
stock option exercises.  These share issuances were offset by the repurchase of 792,216 shares of common stock in 
2007, 3,319,300 shares in 2006, and 1,175,282 shares in 2005 through our stock repurchase plan. 

The remaining information in the table relates to information we have provided in our operations update 

press releases and is intended to supplement the discussion above. 

Overview of Liquidity and Capital Resources 

We own depleting assets.  In order to maintain our current size or to meet our projected growth targets, we 

will have to effectively invest capital into new projects and acquisitions.  The following analysis and discussion 
includes our assessments of market risk and possible effects of inflation and changing prices. 

Sources of cash 

Based on our current forecast, we project that our 2008 cash flows from operations will exceed our 
planned capital investment budget for exploration and development resulting in free cash flow that will be 
available for additional drilling opportunities, acquisitions, share repurchases, or repayment of debt.  Accordingly, 
we do not expect to access the capital markets in 2008.  On January 31, 2008, we closed on the sale of our 
previously announced divestiture of non-core oil and gas properties.  Net proceeds from this transaction, before 
commission costs, was $131.6 million.  These proceeds were used to repay debt under our revolving credit 
facility.  We do anticipate that we will continue to evaluate our property base for the divestiture of properties that 

48 

we consider non-core and we will likely utilize such proceeds to fund our capital programs.  Although our 
working capital is a negative amount, it is important to note that a significant portion of this relates to hedge 
contracts that are in a liability position.  We classify those expected settlements that are anticipated to be settled 
over the year of 2008 as a current item in our balance sheet.  

Our primary sources of liquidity are the cash provided by operating activities, debt financing, sales of 

non-core properties, and access to capital markets.  All of these sources can be impacted by the general condition 
of our industry and by significant fluctuations in oil and gas prices, operating costs, and volumes produced.  We 
have no control over the market prices for oil and natural gas, although we are able to influence the amount of our 
net realized revenues related to oil and gas sales through the use of derivative contracts.  A decrease in market 
prices would reduce expected cash flow from operating activities and could reduce the borrowing base of our 
credit facility as well as the value of non-strategic properties we might consider selling.  Historically, decreases in 
market prices have limited our industry’s access to the capital markets.  The public debt markets for energy 
companies continue to be available to us, although they are significantly less favorable than this time a year 
earlier.  Credit spreads have increased materially and the volume of transactions being placed in the market is 
down dramatically.  The overall credit markets have seen a significant contraction as a result of credit tightening 
caused by widely reported sub-prime and leveraged loan market issues.  Equity and convertible debt financings 
are still an available alternative and are somewhat favorable to energy companies that operate in the exploration 
and production industry.  This is a result of strong commodity prices and the general strength reflected in the 
balance sheets of the companies in this industry as well as the historically low credit defaults of energy 
companies.  We do not, however, anticipate any need to raise either public debt or equity related capital in the 
foreseeable future.  We intend to rely on our current credit facility for borrowings.  However, a significant 
transaction could necessitate the need to raise additional public debt or equity financing.  

Our current credit facility.  We have a five-year, $500 million credit facility agreement with Wachovia 

Bank, Wells Fargo Bank and nine other participating banks.  This credit facility has a borrowing base of 
$1.25 billion.  We have elected a commitment amount of $500 million.  We believe this commitment level is 
adequate for our near-term liquidity requirements.  The credit agreement has a maturity date of April 7, 2010.  We 
must comply with certain financial and non-financial covenants under our existing credit facility.  The Company is 
in compliance with all covenants associated with the credit facility.  As of February 15, 2008, we had $320.0 million 
of available borrowing capacity under this facility.  Interest and commitment fees are accrued based on the 
borrowing base utilization percentage.  Euro-dollar loans accrue interest at LIBOR plus the applicable margin 
from the utilization table located in Note 5 of Part IV, Item 15 of this report, and Alternate Base Rate loans accrue 
interest at Prime plus the applicable margin from the utilization table.  This reduces the amount available under 
the commitment amount on a dollar-for-dollar basis.  Borrowings under the new facility are secured by mortgages 
on the majority of our oil and gas properties and a pledge of the common stock of our material subsidiary 
companies. 

Commitment fees are accrued on the unused portion of the aggregate commitment amount and are 
included in interest expense in the consolidated statements of operations.  We had an outstanding loan balance of 
$285.0 million as of December 31, 2007.  As of December 31, 2007, we had a cash and short-term investment 
balance of $44.7 million.  

We decreased our net borrowings from the previous year by $49.0 million when comparing the ending 

balance sheet amounts.  A substantial increase in the average outstanding credit facility balance throughout 
2007, offset by a decrease in interest rates and an increase in the amount of capitalized interest of $1.9 million, 
resulted in a higher interest expense of $19.9 million in 2007 compared with $8.5 million in 2006.  Our 
weighted-average interest rate paid in 2007 was 5.4 percent and included fees paid on the unused portion of the 
credit facility aggregate commitment amount, amortization of deferred financing costs, amortization of the 
contingent interest embedded derivative associated with the 5.75% Senior Convertible Notes, and the effects of 
interest rate swaps. 

49 

Uses of cash 

We use cash for the acquisition, exploration, and development of oil and gas properties, and for the 
payment of debt obligations, trade payables, income taxes, common stock repurchases, and stockholder dividends.  
During 2007 we spent $637.7 million of cash on capital development and $182.9 million of cash for property 
acquisitions.  These amounts differ from the cost incurred amounts based on the timing of cash payments 
associated with these activities as compared to the accrual based activity upon which the costs incurred amounts 
are presented.  These cash flows were funded using cash inflows from operations and available borrowing 
capacity under our revolving credit facility. 

Expenditures for exploration and development of oil and gas properties and acquisitions are the primary use 

of our capital resources.  We anticipate spending approximately $626 million for capital and exploration 
expenditures in 2008.  The capital expenditures budget was described in more detail earlier in the Outlook for 
2008 section.  The amount and allocation of future capital expenditures will depend upon a number of factors 
including the number and size of available economic acquisitions and drilling opportunities, our cash flows from 
operating and financing activities, and our ability to assimilate acquisitions.  Also, the impact of oil and gas prices 
on investment opportunities, the availability of capital and borrowing facilities, and the success of our 
development and exploratory activities could lead to changes in funding requirements for future development.  
We regularly review our capital expenditure budget to assess changes in current and projected cash flows, 
acquisition opportunities, debt requirements, and other factors. 

The current portion of our income tax expense was 16 percent of our total income tax expense for 2007.  
We make estimated payments during the calendar year and as of December 31, 2007, we anticipate that we have 
an income tax refund with accrued interest due the Company of $1.0 million.   

During 2007 we purchased 792,216 shares of our common stock in the open market at a weighted-
average price of $32.76, including commissions, for a total of $26.0 million.  As of this filing date we have Board 
authorization to repurchase up to an additional 5,207,784 million shares of our common stock under our stock 
repurchase program.  Shares may be repurchased from time to time in open market transactions or privately 
negotiated transactions subject to market conditions and other factors including certain provisions of our existing 
bank credit facility agreement, compliance with securities laws, and the terms and provisions of our stock 
repurchase program. 

In 2007, we paid $6.3 million in dividends to our stockholders.  Our intention is to continue to make these 
dividend payments for the foreseeable future subject to our future earnings, our financial condition, possible credit 
facility covenants, and other currently unexpected factors which could arise. 

The following table presents amounts and percentage changes between years in net cash flows from our 

operating, investing, and financing activities.  The analysis following the table should be read in conjunction with 
our consolidated statements of cash flows in Part IV, Item 15 of this report.

Analysis of cash flow changes between 2007 and 2006 

Operating activities.  Cash received from oil and gas production revenues, net of the realized effects of 

hedging, increased $123.0 million to $925.1 million for the year ended December 31, 2007.  Included in the oil and 
gas production revenue amount is $24.5 million of net realized hedging gains.  The increase was the result of a 
16 percent increase in production and a six percent increase in our net realized price after hedging, resulting in a 

50 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
23 percent increase in production revenue.  Net cash payments made for income taxes decreased $26.7 million 
relative to the prior year as the Company was able to deduct for tax purposes a larger amount of intangible drilling 
costs due to the expanded 2007 capital program. 

Investing activities.  Net cash proceeds from an insurance settlement related to Hurricane Rita totaled 

$5.9 million for the period ended December 31, 2007.  Total cash outflow for 2007 capital expenditures for 
leasehold and drilling activities increased $182.7 million or 40 percent to $637.7 million.  Total cash outflow for 
2007 related to the acquisition of oil and gas properties decreased $87.8 million or 32 percent to $182.9 million. 
Cash received from short-term investments increased $1.4 million and deposits to short-term investments increased 
$1.2 million for the period ended December 31, 2007, as compared to the same period in 2006.  Cash received from 
other for the period ended December 31, 2007 included a deposit of $10 million related to the divestiture of non-core 
oil and gas assets that was completed on January 31, 2008. 

Financing activities.  Net repayments to our credit facility increased $383 million and payments to our 
short-term note payable increased $4.5 million for the period ended December 31, 2007, compared to 2006.  In 
March 2007, we received $280.7 million, net of $6.8 million of deferred financing costs, from the issuance of the 
3.50% Senior Convertible Notes. Our income tax benefit attributable to the exercise of stock options decreased 
$6.2 million to $9.9 million for the year ended December 31, 2007.  We received $7.7 million less from the sale of 
common stock related to stock option exercises and issuance under the employee stock purchase plan in 2007, 
compared to 2006.  Additionally, we invested $97.2 million less to repurchase shares of our common stock during 
2007, compared to the same period in 2006. 

We had $43.5 million in cash and cash equivalents and had a working deficit of $92.6 million as of 
December 31, 2007, compared to $1.5 million in cash and cash equivalents and working capital of $22.9 million as 
of December 31, 2006.  The large increase in the cash balance as of the end of 2007 compared to prior periods was a 
reflection of timing of maturities of the LIBOR denominated tranches on our credit facility. 

Analysis of cash flow changes between 2006 and 2005 

Operating activities.  Cash received from oil and gas production revenue, net of the realized effects of 

hedging, increased $152.5 million to $802.1 million for the year ended December 31, 2006.  Included in the oil and 
gas production revenue amount is $28.2 million of realized hedging gains.  This increase was the result of a 
six percent increase in production offset by lower realized prices.  Net cash payments made for income taxes 
decreased $40.2 million as the Company was able to deduct a larger amount of intangible drilling costs due to the 
expanded capital program.  

Investing activities.  Total cash outflow for 2006 capital expenditures, as adjusted for accruals and including 

acquisitions of oil and gas properties, increased $380.9 million, or 110 percent, to $725.7 million.  This increase 
reflects increased drilling expenditures and net cash paid for oil and gas properties acquired in the Sweetie Peck 
project area in the Permian Basin during 2006. 

Financing activities.  Net borrowings against our credit facility were $334.0 million for the year ended 

December 31, 2006, versus net payments of $37.0 million in 2005.  We paid $123.1 million to acquire shares of our 
common stock under our stock repurchase program in 2006, compared to $28.9 million paid in 2005.  We also 
received $6.5 million more from the exercise of stock options in 2006 compared to 2005, and we had a $16.1 million 
increase in income tax benefit resulting from the exercise of stock options in 2006 compared to 2005. 

We had $1.5 million in cash and cash equivalents and had working capital of $22.9 million as of 
December 31, 2006, compared to $14.9 million in cash and cash equivalents and working capital of $4.9 million as 
of December 31, 2005.

Capital Expenditures 

The following table sets forth certain historical information regarding the costs incurred by us in our oil 
and gas activities.  The below amounts for 2007, 2006, and 2005 include capitalized costs associated with asset 
retirement obligations of $27.6 million, $7.8 million, and $22.8 million, respectively.

The costs we incurred for capital and exploration activities in 2007 increased $120.6 million or 15 percent 

compared to 2006.  This increase was a result of planned increases in drilling activity offset by an $88.1 million 
decrease in acquisitions relative to the prior year.  Increased activity in our drilling program was the primary 
driver of this increase, particularly since cost inflation moderated in 2007. 

Commodity Price Risk and Interest Rate Risk 

We are exposed to market risk, including the effects of changes in oil and gas commodity prices and 
changes in interest rates as discussed below under the caption “Summary of Interest Rate Hedges in Place.”  
Changes in interest rates can affect the amount of interest we earn on our cash, cash equivalents, and short-term 
investments and the amount of interest we pay on borrowings under our revolving credit facility.  Changes in 
interest rates do not affect the amount of interest we pay on our fixed-rate 3.50% Senior Convertible Notes, but do 
affect their fair market value. 

Since we produce and sell natural gas and crude oil, our financial results are affected when prices for 

these commodities fluctuate.  The following table reflects our estimate of the effect on net cash flows from 
operations of a ten percent change in our average realized sales price, inclusive of the impact of hedging, for natural 
gas, for oil, and in combination for the years presented.  These amounts have been reduced by the effective income 
tax rate applicable to each period since a reduction in revenue would reduce cash requirements to pay income taxes.  
General and administrative expenses have not been adjusted.  To fund the capital expenditures we incurred in those 
years we would have been required to utilize different amounts under our credit facility as a source of funds.  In each 
of these years we would have had sufficient borrowing base available under our credit facility to meet this 
contingency without reducing or eliminating expenditures or altering our growth strategy.   

Pro forma effect on net cash flow from 
operations of a ten percent change in 
average realized sales price:

We enter into hedging transactions in order to reduce the impact of fluctuations in commodity prices. 

Note 10 of Part IV, Item 15 of this report contains important information about our oil and gas derivative 
contracts, and additional information is below under the caption Summary of Oil and Gas Production Hedges in 
Place.  We do not anticipate significant changes in existing hedge contracts or derivative contract transactions. 

Summary of Oil and Gas Production Hedges in Place 

Our oil and natural gas derivative contracts include swap and costless collar arrangements.  All contracts 

are entered into for other-than-trading purposes.  Please refer to Note 10 – Derivative Financial Instruments in 
Part IV, Item 15 of this report for additional information regarding accounting for our derivative transactions. 

Our net realized oil and gas prices are impacted by hedges we have placed on future forecasted 
production.  We have historically entered into hedges of existing production around the time we make 
acquisitions of producing oil and gas properties.  Our intent has been to lock in a significant portion of an 
equivalent amount of existing production to the prices we used to evaluate the risked economics of our 
acquisitions.  We also hedge a portion of our forecasted production on a discretionary basis.  As of year end our 
hedged positions of anticipated production through 2011 totaled approximately 11 million Bbls of oil, 70 million 
MMBtu of natural gas, and 1 million Bbls of natural gas liquids. 

In a typical commodity swap agreement, if the agreed upon published third-party index price is lower 

than the swap fixed price, we receive the difference between the index price per unit of production and the agreed 
upon swap fixed price.  If the index price is higher than the swap fixed price, we pay the difference.  For collar 
agreements, we receive the difference between an agreed upon index and the floor price if the index price is below 
the floor price.  We pay the difference between the agreed upon contracted ceiling price and the index price if the 
index price is above the contracted ceiling price.  No amounts are paid or received if the index price is between 
the contracted floor and ceiling prices. 

53 

The following tables describe the volumes, average contract prices, and fair value of contracts we have in 

place as of December 31, 2007.  We seek to minimize basis risk and index the majority of our oil contracts to 
NYMEX prices and our gas contracts to various regional index prices associated with pipelines in proximity to 
our areas of gas production.

Summary of Interest Rate Hedges in Place 

Effective September 13, 2007, we entered into a one year floating-to-fixed interest rate derivative contract 

for a notional amount of $75 million.  Under the agreement, we will pay a fixed rate of 4.90 percent and will be paid 
a variable rate of the one-month LIBOR rate.

In relation to our 5.75% Senior Convertible Notes we entered into fixed-to-floating interest rate swaps on 

$50 million of principal in October 2003.  Due to an increase in interest rates, we entered into a floating-to-fixed 
interest rate swap in April 2005 through the redemption date of the notes on March 20, 2007, for this same notional 
amount of $50 million in order to effectively offset our fixed-to-floating interest rate swaps.  Under the floating-to-
fixed interest rate swap, we were paid a variable interest rate of 235 basis points above the six-month LIBOR rate as 
determined on the semi-annual settlement date and paid a fixed interest rate of 6.85 percent.  The impact of this 
instrument, when combined with the other interest rate swaps, was that we fixed our net liability related to the 
interest rate swaps, and paid a 1.1 percent interest factor on $50 million of notional debt through March 2007.  The 
payment dates of the swap matched exactly with the interest payment dates of the 5.75% Senior Convertible Notes 
and the fixed-to-floating interest rate swaps.   

Market risk is estimated as the potential change in fair value resulting from an immediate hypothetical 

one percentage point parallel shift in the yield curve.  For fixed-rate debt, interest rate changes affect the fair 
market value but do not impact results of operations or cash flows.  Conversely, interest rate changes for 
floating-rate debt generally do not affect the fair market value but do impact future results of operations and 
cash flows, assuming other factors are held constant. The carrying amount of our floating-rate debt typically 
approximates its fair value.  We had $285.0 million of floating rate debt outstanding as of 
December 31, 2007.  Our fixed rate debt outstanding at this same date was $287.5 million associated with the 
3.50% Senior Convertible Notes.   

Please see Note 10 of Part IV, Item 15 of this report for additional information regarding our interest 

rate swaps.

This table includes our 2007 estimated pension liability payment of approximately $1.9 million expected to 

be paid in the second quarter of 2008.  The table also includes the remaining unfunded portion of our estimated 
pension liability of $4.2 million even though we recognize that we cannot determine with accuracy the timing of 
future payments.  We have made payments of $2.2 million, $1.3 million, and $1.1 million in 2007, 2006, and 2005, 
respectively, towards the pension liability.  We have included $216.7 million in other long-term liabilities, which 
represents six years of undiscounted forecasted payments for the Net Profits Plan.  Payments are expected to be 
similar on an annual basis for the years beyond what is shown in this table.  The value recorded on the balance sheet 
reflects the impact of discounting and therefore differs from the amounts disclosed in this table.  The variability in 
the amount of the payments will be a direct reflection of commodity prices, capital expenditures, and operating costs 
in future periods.  Predicting the timing of payments associated with this liability is contingent upon estimates of 
appropriate discount factors, adjusting for risk and time value, and upon a number of factors that we cannot control. 

The scheduled repayment of the long-term credit facility is in 2010.  Accordingly, it has been disclosed in 

the table as such.  Since this is a revolving credit facility, the actual payments will vary significantly.  We anticipate 
refinancing this obligation.  For purposes of this table, we assume that we will net share settle the 3.50% Senior 
Convertible Notes.  Additionally, $42.8 million of interest payments related to the 3.50% Senior Convertible 
Notes are included in the table above.  We have excluded asset retirement obligations because we are not able to 

58 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
accurately predict the precise timing for these amounts.  Pension liabilities and asset retirement obligations are 
discussed in Note 8 and Note 9 of Part IV, Item 15, respectively, and the Net Profits Plan is discussed in Note 7 of 
Part IV, Item 15 of this report. 

This table also includes estimated oil and natural gas derivative payments of $282.9 million based on futures 

market prices as of December 31, 2007.  This amount represents only the cash outflows; it does not include oil and 
gas receipts of $20.6 million that would be paid based on December 31, 2007, market prices.  The net of 
$262.3 million represents cash flows from the intrinsic value of our swap and collar arrangements and differs in 
amount from our recorded fair value, which as of December 31, 2007, was a net liability of $264.1 million.  The fair 
value considers time value and volatility that affect the ultimate fair value.  Both the intrinsic value and fair value 
will change as oil and natural gas commodity prices change.  Please refer to the discussion above under the caption 
Summary of Oil and Gas Production Hedges in Place in Part II, Item 7, Management’s Discussion and Analysis of 
Financial Condition and Results of Operations and to Note 10 – Derivative Financial Instruments in Part IV, Item 15 
of this report for additional information regarding our oil and gas hedges. 

We believe that we will continue to pay annual dividends of $0.10 per share.  We anticipate making cash 

payments for income taxes, dependent on net income and capital spending. 

Off-Balance Sheet Arrangements 

As part of our ongoing business, we have not participated in transactions that generate relationships with 
unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special 
purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements 
or other contractually narrow or limited purposes.  As of and up to December 31, 2007, we have not been 
involved in any unconsolidated SPE transactions. 

We evaluate our transactions to determine if any variable interest entities exist.  If it is determined that we 

are the primary beneficiary of a variable interest entity, that entity is consolidated into our consolidated financial 
statements. 

Critical Accounting Policies and Estimates 

We are engaged in the exploration, exploitation, development, acquisition, and production of natural gas and 

crude oil.  Our discussion of financial condition and results of operations is based upon the information reported in 
our consolidated financial statements.  The preparation of these consolidated financial statements requires us to 
make assumptions and estimates that affect the reported amounts of assets, liabilities, revenues, and expenses as well 
as the disclosure of contingent assets and liabilities as of the date of our financial statements.  We base our decisions 
affecting the estimates we use on historical experience and various other sources that are believed to be reasonable 
under the circumstances.  Actual results may differ from the estimates we calculate due to changing business 
conditions or unexpected circumstances.  Policies we believe are critical to understanding our business operations 
and results of operations are detailed below.  For additional information on our significant accounting policies you 
should see Note 1 – Summary of Significant Accounting Policies, Note 9 – Asset Retirement Obligations, and 
Note 12 – Disclosures About Oil and Gas Producing Activities in Part IV, Item 15 of this report. 

Oil and gas reserve quantities.  Estimated reserve quantities and the related estimates of future net cash 

flows are the most important estimates for an exploration and production company because they affect the perceived 
value of our Company, are used in comparative financial analysis ratios and are used as the basis for the most 
significant accounting estimates in our financial statements.  The significant accounting estimates include the 
periodic calculations of depletion, depreciation, and impairment for our proved oil and gas properties and the 
estimates of our liability for future payments under the Net Profits Plan.  Proved oil and gas reserves are the 
estimated quantities of crude oil, natural gas, and natural gas liquids which geological and engineering data 
demonstrate with reasonable certainty to be recoverable in future periods from known reservoirs under existing 
economic and operating conditions.  Future cash inflows and future production and development costs are 
determined by applying benchmark prices and costs, including transportation, quality, and basis differentials, in 
effect at the end of each period to the estimated quantities of oil and gas remaining to be produced as of the end of 

59 

that period.  Expected cash flows are reduced to present value using a discount rate that depends upon the purpose 
for which the reserve estimates will be used.  For example, the standardized measure calculation required by 
SFAS No. 69, Disclosures about Oil and Gas Producing Activities, requires a ten percent discount rate to be applied.  
Although reserve estimates are inherently imprecise, and estimates of new discoveries and undeveloped locations are 
more imprecise than those of established producing oil and gas properties, we make a considerable effort in 
estimating our reserves, including using independent reserve engineering consultants.  We expect that periodic 
reserve estimates will change in the future as additional information becomes available or as oil and gas prices and 
operating and capital costs change.  We evaluate and estimate our oil and gas reserves at December 31 and June 30 
of each year.  For purposes of depletion, depreciation, and impairment, reserve quantities are adjusted at all interim 
periods for the estimated impact of additions and dispositions.  Changes in depletion, depreciation, or impairment 
calculations caused by changes in reserve quantities or net cash flows are recorded in the period that the reserve 
estimates change. 

The following table presents information regarding reserve changes from period to period that reflect 

changes from items we do not control, such as price, and from changes resulting from better information due to 
production history, and well performance.  These changes do not require a capital expenditure on our part, but may 
have resulted from capital expenditures we incurred to develop other estimated proved reserves.

Over the three-year period, we added 720.7 BCFE of reserves.  Of these, 83.5 BCFE, or 12 percent, was a 

result of changes in estimates based on the performance of our oil and gas properties.  A 5.4 BCFE increase in 
reserves was a result of price changes.  As previously noted, oil and gas prices are volatile, and estimates of 
reserves are inherently imprecise.  Consequently, we anticipate we will continue to experience these types of 
changes.

Successful efforts method of accounting.  Generally accepted accounting principles provide for two 
alternative methods for the oil and gas industry to use in accounting for oil and gas producing activities.  These two 
methods are generally known in our industry as the full cost method and the successful efforts method.  Both 
methods are widely used.  The methods are different enough that in many circumstances the same set of facts will

provide materially different financial statement results within a given year.  We have chosen the successful efforts 
method of accounting for our oil and gas producing activities, and a detailed description is included in Note 1 of 
Part IV, Item 15 of this report. 

Revenue recognition.  Our revenue recognition policy is significant because revenue is a key component of 

our results of operations and our forward-looking statements contained in our analyses of liquidity and capital 
resources.  We derive our revenue primarily from the sale of produced natural gas and crude oil.  We report revenue 
as the gross amounts we receive before taking into account production taxes and transportation costs, which are 
reported as separate expenses.  Revenue is recorded in the month our production is delivered to the purchaser, but 
payment is generally received between 30 and 90 days after the date of production.  No revenue is recognized unless 
it is determined that title to the product has transferred to a purchaser.  At the end of each month we make estimates 
of the amount of production delivered to the purchaser and the price we will receive.  We use our knowledge of our 
properties, their historical performance, NYMEX and local spot market prices, and other factors as the basis for 
these estimates.  Variances between our estimates and the actual amounts received are recorded in the month 
payment is received.  A ten percent change in our year-end revenue accrual would have impacted net income before 
tax by $11.6 million in 2007. 

Crude oil and natural gas hedging.  Our crude oil and natural gas hedging contracts are intended and usually 
qualify for cash flow deferral hedge accounting under SFAS No. 133.  Under this accounting pronouncement a 
majority of the gain or loss from a contract qualifying as a cash flow hedge is deferred as to statement of 
operations recognition.  The position reflected in the statement of operations is based on the actual settlements 
with the counterparty.  If our natural gas and crude oil hedge contracts did not qualify for hedge accounting 
treatment or we chose not to use this hedge accounting methodology, our periodic consolidated statements of 
operations could include significant changes in the estimate of non-cash derivative gain or loss due to swings in 
the value of these contracts.  Consequently, we would report a different amount for oil and gas hedge loss in our 
statements of operations.  These fluctuations could be especially significant in a volatile pricing environment such 
as what we have encountered over the last three years.  The amounts recorded to accumulated other 
comprehensive income (loss) of $(170.0) million, $69.0 million, and $(57.2) million, for 2007, 2006, and 2005, 
respectively, would have increased or (decreased) net income after tax if our hedges did not qualify as cash flow 
deferral hedges under SFAS No. 133.  

Change in Net Profits Plan Liability.  We record the estimated liability of future payments for our Net 

Profit Plan.  The estimated liability is calculated based on a number of assumptions, including estimates of oil and 
gas reserves, recurring and workover lease operating expense, product and ad valorem tax rates, present value 
discount factors, and pricing assumptions.  Additional discussion is included in the analysis in the above section 
titled Overview of the Company, under the heading Net Profits Plan.   

Asset retirement obligations.  We are required to recognize an estimated liability for future costs associated 

with the abandonment of our oil and gas properties.  We base our estimate of the liability on our historical 
experience in abandoning oil and gas wells projected into the future based on our current understanding of federal 
and state regulatory requirements.  Our present value calculations require us to estimate the economic lives of our 
properties, assume what future inflation rates apply to external estimates, and determine what credit adjusted risk-
free rate to use.  The impact to the consolidated statement of operations from these estimates is reflected in our 
depreciation, depletion, and amortization calculations and occurs over the remaining life of our oil and gas 
properties. 

Valuation of long-lived and intangible assets.  Our property and equipment is recorded at cost.  An 
impairment allowance is provided on unproved property when we determine that the property will not be developed 
or the carrying value will not be realized.  We evaluate the realizability of our proved properties and other long-lived 
assets whenever events or changes in circumstances indicate that impairment may be appropriate.  Our impairment 
test compares the expected undiscounted future net revenues from a property, using escalated pricing, with the 
related net capitalized costs of the property at the end of each period.  When the net capitalized costs exceed the 
undiscounted future net revenue of a property, the cost of the property is written down to our estimate of fair value, 
which is determined by applying a discount rate that we believe is indicative of the current market.  Our criteria for 

61 

 
an acceptable internal rate of return are subject to change over time.  Different pricing assumptions or discount rates 
could result in a different calculated impairment. 

Income taxes.  We provide for deferred income taxes on the difference between the tax basis of an asset or 

liability and its carrying amount in our financial statements in accordance with SFAS No. 109, “Accounting for 
Income Taxes.”  This difference will result in taxable income or deductions in future years when the reported 
amount of the asset or liability is recovered or settled, respectively.  Considerable judgment is required in 
determining when these events may occur and whether recovery of an asset is more likely than not.  Additionally, 
our federal and state income tax returns are generally not filed before the consolidated financial statements are 
prepared, therefore we estimate the tax basis of our assets and liabilities at the end of each period as well as the 
effects of tax rate changes, tax credits, and net operating and capital loss carryforwards and carrybacks.  Adjustments 
related to differences between the estimates we used and actual amounts we reported are recorded in the period in 
which we file our income tax returns.  These adjustments and changes in our estimates of asset recovery could have 
an impact on our results of operations.  A one percent change in our effective tax rate would have affected our 
calculated income tax expense by $2.9 million for the year ended December 31, 2007. 

Stock-based compensation.  Prior to 2006 we accounted for stock-based compensation using the intrinsic 
value recognition and measurement principles detailed in APB No. 25.  No stock-based employee compensation 
expense relating to stock options has been reflected in our expense as all options granted under our plans had an 
exercise price equal to the market value of the underlying common stock on the date of grant.  We used the Black-
Scholes option valuation model to calculate the disclosures required under Statement of Financial Accounting 
Standards No. 123.  As of January 1, 2006, we adopted the provisions of Statement of Financial Accounting 
Standards No. 123(R).  This statement required us to record expense associated with the fair value of stock-based 
compensation.  We have recorded expense associated with the issuance of restricted stock units since the plan was 
adopted in 2004 and units were first issued.  Going forward this expense will decrease on a relative per share basis 
for all units that have already been issued because the accounting standard requires cost recognition using fair value 
estimates of the restricted stock units, rather than intrinsic value.

Comparison of Financial Results and Trends between 2007 and 2006 

Oil and gas production revenues.  Average net daily production increased 16 percent to a record 

294.5 MMCFE for 2007 compared with 254.2 MMCFE in 2006.  The following table presents specific 
components that contributed to the increase in revenue between the two periods:

The revenue increases in this table also reflect the difference in oil and gas prices received between 

the comparable periods.  The production increases are offset by natural declines in production from older 
properties to result in the net increase in production between the years presented.  Additional production costs 
reflect increases resulting from inflation and competition for resources. 

Oil and gas realized hedge gain (loss).  The 13 percent decrease in total oil and gas hedge gain to 
$24.5 million was caused by a change in the composition of our hedge position and changes in oil and gas 
commodity prices.   

Marketed gas system revenue and expense.  Marketed gas system revenue increased $24.2 million to 

$45.1 million for the year-ended December 31, 2007, compared with $20.9 million for the comparable period of 
2006.  The increase is due to the addition of a new marketed gas system in western Oklahoma that increased the 
number of wells for which we currently market gas, as well as increased production in the Woodford shale formation 
located in Coal County, Oklahoma.  Concurrent with the increase in marketed gas system revenue, marketed gas 
system expense increased $24.0 million to $42.5 million for the year-ended December 31, 2007, compared with 
$18.5 million for the comparable period of 2006. 

Other revenues.  Other revenues increased $7.8 million to $8.7 million for the year ended 

December 31, 2007, compared with $942,000 for the comparable period of 2006.  The increase is due primarily to a 
$5.2 million gain associated with a global insurance settlement attributed to Hurricane Rita.  The gain calculation is 
net of approximately $12.1 million of costs associated with the plugging and abandonment of one offshore 
platform.  We continue to closely monitor the activities associated with these properties.  Any significant variation 
between actual and estimated plugging and abandonment and outside-operated damage repair costs will impact 
the final determination of the insurance settlement gain.  We assume that all work will be completed and expect 
adjustments to the gain will be finalized during the second quarter of 2008. 

Oil and gas production expenses.  Total production costs increased $41.6 million or 24 percent to 

$218.2 million for 2007, from $176.6 million in 2006.  Our current year and prior year acquisition of properties 
added $13.6 million of incremental production costs, and other wells completed in 2006 and 2007 added

$13.7 million of incremental production costs in 2007 that were not reflected in 2006. The production cost 
increases are offset by natural declines in production costs from older properties to result in the net increase in 
production costs between the years presented.  We experienced an increase in production taxes consistent with 
the increase in revenue from higher realized prices. 

Total oil and gas production costs per MCFE increased $0.12 to $2.03 for 2007, compared with $1.91 

for 2006.  This increase is comprised of the following:  

•  A $0.02 increase in overall transportation cost due to an increase in the Rocky Mountain region 

resulting from a change in the sale measurement point, as well as newly drilled wells with higher 
transportation costs 

•  A $0.11 increase in recurring lease operating expense related to continued cost pressure from the oil and 

gas service sector 

•  A $0.05 overall decrease in lease operating expense relating to workover expense, primarily in the 

Rockies 

•  A $0.04 increase in production taxes related to increase production in the Permian region.  

Depletion, Depreciation, and Amortization.  DD&A increased $73.1 million, or 47 percent, to 

$227.6 million in 2007 compared with $154.5 million in 2006.  DD&A expense per MCFE increased 27 percent to 
$2.12 in 2007 compared to $1.67 in 2006.  This increase reflects overall upward cost pressure in the industry and 
specifically our drilling in 2007 and 2006 that added costs at a higher per unit rate relative to the prior year’s base.  
The DD&A per MCFE rate was further affected by upward adjustments to reserves due to pricing differences 
between December 31, 2007, and December 31, 2006 although this had the impact of a general lowering of DD&A 
as compared to what DD&A would have been with the upward revisions of 40.9 BCFE of proved reserves. 

Exploration expense.  Exploration expense increased $6.8 million or 13 percent to $58.7 million in 2007 

compared with $51.9 million for 2006.  This increase is due to a $7.5 million increase in geologic and geophysical 
expense to support a larger overall program as well as a $4.2 million increase in exploratory dry hole expense related 
to three wells located in the Gulf Coast region and one in the Rockies region.  These increases were offset by a 
$4.9 million decrease in exploration overhead expense related to a reduction in amounts recorded in exploration 
expense related to payments under the Net Profits Plan.  In the current year we had a change in our accounting 
estimate to reflect the view that Net Profits Plan distributions should be reclassified to exploration overhead only for 
individuals who are currently employed by us and who continue to be involved in our exploration efforts.  Therefore 
Net Profits Plan payments associated with the distributions under the Net Profits Plan for ex-employees were 
reclassified to general and administrative expense since there is no longer any functional link to exploration expense 
as there is by definition no periodic costs associated with geologic, geophysical and exploration related work by 
those ex-employees. 

General and administrative.  General and administrative expenses increased $21.3 million or 55 percent 
to $60.1 million for 2007, compared with $38.9 million for 2006.  G&A increased $0.14 to $0.56 per MCFE for 
2007 compared to $0.42 per MCFE for the period in 2006 as G&A grew at a faster rate than the 16 percent 
increase in production.  A 23 percent increase in employee count has contributed to an increase in base 
employee compensation, including taxes and benefits, of approximately 29 percent, or $8.5 million, between the 
year ended December 31, 2007, and the same period of 2006.   

An increase in oil and gas prices in 2007 triggered additional Net Profits Plan payouts and has increased the 
amounts payable to plan participants.  Additionally, an increased percentage amount of the distribution dollars under 
the Net Profits Plan associated with general and administrative expense contributed to the current period realized 
expense associated with the Net Profits Plan increasing by $5.8 million in 2007 compared with the same period in 
2006.  An increase in employee count resulted in an increase in cash bonus expense of $2.4 million to $5.2 million 
for the year ended December 31, 2007, compared with $2.8 million for the year ended December 31, 2006. 

RSU bonus expense remained relatively flat decreasing by $100,000 for the year ended December 31, 2007, 

compared with the same period in 2006.  Compensation expense related to stock options for the year ended 

65 

December 31, 2007, decreased $1.4 million to $437,000 from $1.9 million in the comparable period in 2006 because 
virtually all the stock options are now vested.  No stock options have been granted since 2004. 

The amounts described above, combined with a net $5.4 million increase in other G&A expense (including 
office supplies and employee development), were offset by a $5.0 million decrease in the amount of G&A that was 
allocated to exploration expense due to the aforementioned change in our Net Profits Plan accounting estimate and a 
$4.3 million increase in COPAS overhead reimbursements.  COPAS overhead reimbursements from operations 
increased due to an increase in our operated well count from our drilling program.   

Change in Future Net Profits Plan Liability.  For the year ended December 31, 2007, this expense 

increased $27.1 million to $50.8 million from $23.8 million for 2006.  This increase reflects a decrease in the 
discount rate used to calculate the present value of future payments from a base rate of 15 percent to 12 percent.  
The decrease in the discount rate to the 12 percent resulted from our divestiture marketing process and our 
assessment that the overall market for proved oil and gas reserves is ever more competitive.  This liability is a 
significant management estimate.  Adjustments to the liability are subject to estimation and may change 
dramatically from period-to-period based on assumptions used for production rates, reserve quantities, commodity 
pricing, discount rates, production tax rates, and production costs. 

Interest expense.  Interest expense increased by $11.4 million to $19.9 million for 2007 compared to 

$8.5 million for 2006. The increase reflects an increase in our average outstanding borrowings in 2007 
compared with 2006.  Additionally, the increase reflects that we have $287.5 million of 3.50% Senior 
Convertible Notes outstanding at December 31, 2007, compared with 100.0 million of 5.75% Senior 
Convertible Notes outstanding as of December 31, 2006.  We also capitalized $5.4 million of interest in 2007 
compared to $3.5 million in 2006. 

Income tax expense.  Income tax expense totaled $110.6 million for 2007 and $105.3 million in 2006, 

resulting in effective tax rates of 36.8 percent and 35.7 percent, respectively.  The effective rate change from 
2006 reflects changes in the mix of the highest marginal state tax rates as a result of enacted Texas margin tax 
legislation, the benefit of federal and state estimated percentage depletion expense, acquisition and drilling 
activity, and also reflects other permanent differences including differing estimated effects between years of the 
domestic production activities deduction. 

The current portion of income tax expense in 2007 is $17.6 million compared to $30.5 million in 2006.  

These amounts are 16 percent and 29 percent of total income tax expense for the respective periods.  The 
decrease resulted from significant increased drilling activity reflecting the deduction of intangible drilling costs 
in the year incurred, thereby reducing current taxable income.  We project that the current portion of taxable 
income will be similar in 2008.   

Comparison of Financial Results and Trends between 2006 and 2005 

Oil and gas production revenues.  Average net daily production increased six percent to a record 

254.2 MMCFE for 2006 compared with 239.4 MMCFE in 2005.  The following table presents specific 
components that contributed to the increase in revenue between the two periods:

The revenue increases in this table also reflect the difference in oil and gas prices received between 
the comparable periods.  The production increases were offset by natural declines in production from older 
properties to result in the net increase in production between the years presented.  Additional production costs 
reflect increases resulting from inflation and competition for resources. 

Oil and gas realized hedge gain (loss).  The 225 percent increase in total oil and gas hedge gain to 
$28.2 million was caused by a change in the composition of our hedge position and changes in oil and gas 
commodity prices.   

Oil and gas production expenses.  Total production costs increased $33.7 million or 24 percent to 
$176.6 million for 2006, from $142.9 million in 2005.  The acquisition of properties added $1.4 million of 
incremental production costs, prior year acquisitions of properties added $5.2 million of incremental production 
costs, and other wells completed in 2005 and 2006 added $15.3 million of incremental production costs in 2006 
that were not reflected in 2005.  We experienced an increase in production taxes consistent with the increase in 
revenue from higher realized prices. 

Total oil and gas production costs per MCFE increased $0.27 to $1.91 for 2006, compared with $1.64 

for 2005.  This increase was comprised of the following:  

•  A $0.02 decrease in production taxes, due to a $0.04 decrease in our Rocky Mountain region resulting 

from an increase in new production, which qualifies for incentive tax rates, that was partially offset by a 
minor increase in our Mid-Continent region resulting from higher natural gas revenues 

•  A $0.03 increase in overall transportation cost, due to an increase in the Rocky Mountain region 
resulting from a change in the sale measurement point, as well as newly drilled wells with higher 
transportation costs 

•  A $0.20 increase in recurring LOE related to continued increases in costs for oil and gas service sector 

resources 

•  A $0.06 overall increase in LOE relating to workover charges, mainly due to activity in the Rockies.  

Depletion, Depreciation, and Amortization.  DD&A increased $21.8 million or 16 percent to $154.5 million 

in 2006 compared with $132.8 million in 2005.  DD&A expense per MCFE increased 10 percent to $1.67 in 2006 
compared to $1.52 in 2005.  This increase reflected overall upward cost pressure in the industry and specifically our 
acquisitions and drilling in 2006 and 2005 that added costs at a higher per unit rate.  The DD&A per MCFE rate was 
further affected by downward adjustments to reserves due to pricing differences between December 31, 2006 and 
December 31, 2005. 

Proved Property Impairment.  St. Mary recorded a $7.2 million impairment of proved oil and gas properties 

in 2006 compared with no impairment in 2005.  This impairment was primarily due to declining performance and 
downward adjustments to reserves for properties located in East Texas. 

Exploration expense.  Exploration expense increased $7.0 million or 15 percent to $51.9 million in 
2006 compared with $44.9 million for 2005.  This increase was due to a $3.3 million increase in exploration 
overhead related to increases in payments made under the Net Profits Plan and increases in the size of our 
geologic and exploration staff.  Additionally, the increase in exploration expense was partially related to an 
approximate $2.1 million increase in exploratory dry hole expense and a $1.6 million increase in geologic and 
geophysical expense to support a larger overall program. 

General and administrative.  General and administrative expenses increased $6.1 million or 19 percent 
to $38.9 million for 2006, compared with $32.8 million for 2005.  G&A increased $0.05 to $0.42 per MCFE for 
2006 compared to $0.37 per MCFE for the period in 2005 as G&A grew at a faster rate than the six percent 
increase in production. 

A 16 percent increase in employee count contributed to an increase in base employee compensation of 
approximately 18 percent, or $3.5 million, between the year ended December 31, 2006, and the same period of 
2005.  Oil and gas price increases triggered additional Net Profits Plan payouts and increased the amounts payable to 

67 

plan participants.  Consequently, the realized expense associated with the Net Profits Plan increased by $5.4 million 
in 2006 compared with the same period in 2005.  A decrease in the bonus percentage resulted in a decrease in the 
accrued cash bonus expense of $5.0 million to $2.8 million for the year ended December 31, 2006, compared with 
$7.8 million for the year ended December 31, 2005. 

RSU bonus expense was $1.5 million higher for the year ended December 31, 2006, as compared to the year 

ended December 31, 2005, which was due to the increase in amortization of stock-based compensation expense.  In 
2006, we recorded expense for four periods of RSU grants while there were only three grants recorded in 2005.  
Also in 2006, we included the grant made in 2006 for 2005 performance and the additional accrual of the expense 
estimated for the 2006 plan year.  This increase was partially offset by a decrease in RSU bonus expense for the year 
ended December 31, 2006, compared with the same period in 2005.  This decrease correlated to the decrease in cash 
bonus expense and reflected an evaluation of our overall performance for 2006 including reserve replacement, 
production, and net asset value per share growth factors. 

As a result of the implementation of SFAS No. 123(R) on January 1, 2006, we recorded $2.2 million of 
compensation expense in 2006 related to stock options and the ESPP.  The above amounts combined with a net 
$5.1 million increase in other G&A expense, including payroll tax and 401(k) contribution expense, were offset by a 
$3.2 million increase in the amount of G&A that was allocated to exploration expense due to the aforementioned 
incentive plan increases as well as increases in the size of our technical exploration staff and a $3.4 million increase 
in COPAS overhead reimbursements.  COPAS overhead reimbursements from operations increased due to an 
increase in our operated well count from our drilling program.   

Change in Future Net Profits Plan Liability.  For the year ended December 31, 2006, this expense 
decreased $82.5 million to $23.8 million from $106.3 million for 2005.  This decrease reflects a smaller change in 
future oil and gas prices as compared to 2005 when we experienced significant increases in prices.  Since the 
prices used in the calculation were much more comparable in the year-end 2006 calculation to that of the 2005 
calculation, the degree of increase was much less in 2006.  This liability is a significant management estimate.  
Adjustments to the liability are subject to estimation and may change dramatically from period-to-period based on 
assumptions used for production rates, reserve quantities, commodity pricing, discount rates, production tax rates, 
and production costs. 

Interest expense.  Interest expense increased by $308,000 to $8.5 million for 2006 compared to 

$8.2 million for 2005.  The increase reflected an increase in our average outstanding borrowings and higher 
interest rates on the floating rate portion of our long-term debt.  We also capitalized $3.5 million in 2006 
compared to $1.9 million in 2005. 

Income tax expense.  Income tax expense totaled $105.3 million for 2006 and $86.3 million in 2005, 
resulting in effective tax rates of 35.7 percent and 36.3 percent, respectively.  The effective rate change from 
2005 reflected changes in the mix of the highest marginal state tax rates as a result of enacted Texas margin tax 
legislation, the benefit of estimated percentage depletion for both federal and state income taxes, acquisition and 
drilling activity, and also reflected other permanent differences including differing estimated effects between 
years of the domestic production activities deduction. 

The current portion of income tax expense in 2006 was $30.5 million compared to $80.8 million in 

2005.  These amounts comprised 29 percent and 94 percent of total income tax expense for the respective 
periods.  The decrease resulted from a significant increase in drilling activity, whereby we deducted intangible 
drilling costs in the year it was incurred and reduced our current taxable income. 

Other Liquidity and Capital Resource Information 

Pension Benefits 

Substantially all of our employees who meet age and service requirements participate in a non-
contributory defined benefit pension plan.  On December 31, 2006, the Company adopted the recognition and 
disclosure provisions of Statement of Financial Accounting Standards No. 158, "Employers’ Accounting for 

68 

Defined Benefit Pension and Other Postretirement Plans, an amendment of Statement of Financial Accounting 
Standards No 87, 88, 106 and 132(R)".  Statement of Financial Accounting Standards No. 158 requires the 
Company to recognize the funded status (i.e., the difference between the fair value of plan assets and the 
projected benefit obligation) of its pension plan in the December 31, 2006 consolidated balance sheet as either 
an asset or a liability, with a corresponding adjustment to accumulated other comprehensive income, net of tax.  
At December 31, 2007, and December 31, 2006, we had a recorded balance of $2.5 million and $2.6 million, 
respectively, of pre-tax loss in accumulated other comprehensive income as a result of this new pronouncement.  
We believe this obligation will be funded from future cash flow from operating activities.  For purposes of 
calculating our obligation under the plan, we have used an expected return on plan assets of 7.5 percent.  We 
think this rate of return is appropriate over the long-term given the 60 percent equity and 40 percent debt 
securities mix of investment of plan assets and the historical rate of return provided by equity and debt securities 
since the 1920s.  Our actual rate of return was 6.5 percent for 2007 and was 14.1 percent for 2006.  The 
difference in investment income using our projected rate of return compared to our actual rates of return for the 
past two years was not material and will not have a material effect on the results of operation or cash flow from 
operating activities in future years. 

For the 2007 plan year, a 0.20 percentage point increase in the discount rate and a 0.50 percentage point 

increase in the lump sum interest rate, netted with a larger than expected increase in base salaries and an increase in 
new participants, caused a $161,000 increase in the projected benefit obligation of the plan.  We do not believe this 
change was material and project that it will not have a material effect on the results of operations or on cash flow 
from operating activities in future periods. 

We also have a supplemental non-contributory defined benefit pension plan that covers certain 
management employees.  There are no plan assets for this plan.  For the 2007 plan year, a 0.20 percentage point 
increase in the discount rate and a 0.50 percentage point increase in the lump sum interest rate caused a $62,000 
decrease in the projected benefit obligation for this plan.  This plan’s accumulated benefit obligation was 
$1.0 million at December 31, 2007, and $1.5 million at December 31, 2006.  We believe this obligation will be 
funded from future cash flow from operating activities. 

Accounting Matters 

We refer you to Note 4 – Income Taxes and Note 5 – Long-term Debt in Part IV, Item 15 of this 

report for information regarding accounting matters related to FASB Interpretation No. 48, “Accounting for 
Uncertainty in Income Taxes – An Interpretation of FASB Statement No. 109” and FASB Staff Position APB 
14-a, “Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion 
(Including Partial Cash Settlement)”. 

In September 2006 the FASB issued Statement of Financial Accounting Standards No. 157, “Fair Value 

Measurements”, which defines fair value, establishes a framework for measuring fair value, and expands 
disclosures about fair value measurements.  The provisions of SFAS No. 157 will be effective as of the beginning 
of the Company’s 2008 fiscal year.  The adoption of SFAS No. 157 has no impact on the Company’s consolidated 
financial statements, however, it will require changes in certain disclosures.  

In February 2007 the FASB issued Statement of Financial Accounting Standards No. 159, “The Fair 

Value Option for Financial Assets and Financial Liabilities”, which expands the use of fair value accounting but 
does not affect existing standards which require assets or liabilities to be carried at fair value.  SFAS No. 159 
allows entities to choose, at specified election dates, to measure eligible financial assets and liabilities at fair value 
that are not otherwise required to be measured at fair value.  If a company elects the fair value option for an 
eligible item, changes in that item's fair value in subsequent reporting periods must be recognized in current 
earnings.  SFAS No. 159 also establishes presentation and disclosure requirements designed to draw comparisons 
between entities that elect different measurement attributes for similar assets and liabilities.  If elected, SFAS 
No. 159 is effective for fiscal years beginning after November 15, 2007.  SFAS No. 159 will be effective for the 
Company beginning with the 2008 fiscal year.  The Company did not elect the fair value option.  There is no 
impact on the Company’s consolidated financial statements.

Environmental 

St. Mary’s compliance with applicable environmental regulations has not resulted in any significant capital 
expenditures or materially adverse effects to our liquidity or results of operations.  We believe we are in substantial 
compliance with environmental regulations and do not currently foresee that material expenditures will be required 
in the future.  However, we are unable to predict the impact that future compliance with regulations may have on 
future capital expenditures, liquidity, and results of operations.

ITEM 9A. 

CONTROLS AND PROCEDURES 

We maintain a system of disclosure controls and procedures that are designed to ensure that information 

required to be disclosed in our SEC reports is recorded, processed, summarized, and reported within the time periods 
specified in the SEC’s rules and forms, and to ensure that such information is accumulated and communicated to our 
management, including the Chief Executive Officer and the Chief Financial Officer, as appropriate, to allow timely 
decisions regarding required disclosure. 

We carried out an evaluation, under the supervision and with the participation of our management, including 

the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the design and operation of our 
disclosure controls and procedures as of the end of the period covered by this Annual Report on Form 10-K/A.  
Based upon that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that our 
disclosure controls and procedures are effective for the purposes discussed above as of the end of the period covered

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING 

To the Stockholders’ of St. Mary Land & Exploration Company 

Management of the Company is responsible for establishing and maintaining adequate internal control 

over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, 
as amended.  The Company’s internal control over financial reporting is designed to provide reasonable assurance 
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in 
accordance with generally accepted accounting principles.  The Company’s internal control over financial 
reporting includes those policies and procedures that: 

(i) 

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the 
transactions and dispositions of the assets of the Company; 

(ii)  provide reasonable assurance that transactions are recorded as necessary to permit preparation of 

financial statements in accordance with generally accepted accounting principles, and that receipts 
and expenditures of the Company are being made only in accordance with authorizations of 
management and directors of the Company; and 

(iii)  provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, 
use, or disposition of the Company’s assets that could have a material effect on the financial 
statements. 

Because of the inherent limitations, internal control over financial reporting may not prevent or detect 
misstatements.  Also, projections of any evaluation of effectiveness to future periods are subject to the risk that 
controls may become inadequate because of changes in conditions, or that the degree of compliance with the 
policies or procedures may deteriorate. 

Management assessed the effectiveness of the Company’s internal control over financial reporting as of 

December 31, 2007.  In making this assessment, management used the criteria set forth by the Committee of 
Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework. 

Based on our assessment and those criteria, management believes that the Company maintained effective 

internal control over financial reporting as of December 31, 2007. 

The Company’s independent registered public accounting firm has issued an attestation report on the 

Company’s internal controls over financial reporting.  That report immediately follows this report.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors and Stockholders of 
St. Mary Land & Exploration Company and Subsidiaries 
Denver, Colorado 

We have audited the internal control over financial reporting of St. Mary Land & Exploration Company and 
subsidiaries (the “Company”) as of December 31, 2007, based on criteria established in Internal Control—
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.  The 
Company’s management is responsible for maintaining effective internal control over financial reporting and for 
its assessment of the effectiveness of internal control over financial reporting.  Our responsibility is to express an 
opinion on the Company’s internal control over financial reporting based on our audit. 

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board 
(United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about 
whether effective internal control over financial reporting was maintained in all material respects.  Our audit 
included obtaining an understanding of internal control over financial reporting, assessing the risk that a material 
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the 
assessed risk, and performing such other procedures as we considered necessary in the circumstances.  We believe 
that our audit provides a reasonable basis for our opinion. 

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the 
company’s principal executive and principal financial officers, or persons performing similar functions, and 
effected by the company’s board of directors, management, and other personnel to provide reasonable assurance 
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in 
accordance with generally accepted accounting principles.  A company’s internal control over financial reporting 
includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, 
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable 
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance 
with generally accepted accounting principles, and that receipts and expenditures of the company are being made 
only in accordance with authorizations of management and directors of the company; and (3) provide reasonable 
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the 
company’s assets that could have a material effect on the financial statements. 

Because of the inherent limitations of internal control over financial reporting, including the possibility of 
collusion or improper management override of controls, material misstatements due to error or fraud may not be 
prevented or detected on a timely basis.  Also, projections of any evaluation of the effectiveness of the internal 
control over financial reporting to future periods are subject to the risk that the controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may 
deteriorate.  

In our opinion, the Company maintained, in all material respects, effective internal control over financial 
reporting as of December 31, 2007, based on the criteria established in Internal Control—Integrated Framework 
issued by the Committee of Sponsoring Organizations of the Treadway Commission.   

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States), the consolidated financial statements as of and for the year ended December 31, 2007, of the 
Company, and our report dated February 21, 2008, expressed an unqualified opinion on those financial 
statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors and Stockholders of 
St. Mary Land & Exploration Company and Subsidiaries 
Denver, Colorado 

We have audited the accompanying consolidated balance sheets of St. Mary Land & Exploration 
Company and subsidiaries (the “Company”) as of December 31, 2007 and 2006, and the related 
consolidated statements of operations, stockholders’ equity and comprehensive income, and cash 
flows for each of the three years in the period ended December 31, 2007.  These financial 
statements are the responsibility of the Company’s management.  Our responsibility is to express 
an opinion on these financial statements based on our audits. 

We conducted our audits in accordance with the standards of the Public Company Accounting 
Oversight Board (United States).  Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free of material 
misstatement.  An audit includes examining, on a test basis, evidence supporting the amounts and 
disclosures in the financial statements.  An audit also includes assessing the accounting principles 
used and significant estimates made by management, as well as evaluating the overall financial 
statement presentation.  We believe that our audits provide a reasonable basis for our opinion. 

In our opinion, such consolidated financial statements present fairly, in all material respects, the 
financial position of St. Mary Land & Exploration Company and subsidiaries as of 
December 31, 2007 and 2006, and the results of their operations and their cash flows for each of 
the three years in the period ended December 31, 2007, in conformity with accounting principles 
generally accepted in the United States of America.   

As discussed in Note 1 and Note 8 to the financial statements, the Company changed its method 
of accounting and disclosure for stock based compensation and its defined benefit plans in 2006.  

We have also audited, in accordance with the standards of the Public Company Accounting 
Oversight Board (United States), the Company’s internal control over financial reporting as of 
December 31, 2007, based on the criteria established in Internal Control—Integrated Framework 
issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our 
report dated February 21, 2008, expressed an unqualified opinion on the Company’s internal 
control over financial reporting.

As of December 31, 2007, 2006, and 2005, $116.9 million, $73.5 million, and $51.0 million, respectively, are included as 
additions to oil and gas properties and as increases to 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.  

In May 2007 and 2006, July 2007 and 2006 , and May 2005, the Company issued 26,292, 26,076, 6,212, 3,751 and 13,926 
shares, respectively, of common stock from treasury to its non-employee directors pursuant to the Company's
non-employee director stock compensation plan.  The Company recorded compensation expense related to the
issuances of shares to non-employee directors of $983,500, $976,000 and $178,000 for the years ended December 31, 2007, 
2006 and 2005, respectively.

In March 2007 the Company called the 5.75% Senior Convertible Notes for redemption.  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.  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 and a corresponding increase in additional paid-in 
capital that is a result of the recognition of the cumulative excess tax benefit earned by the Company associated with the
contingent interest feature of this note.

In June 2006 the Company hired a new senior executive.  In doing so, the Company issued 13,784 shares of stock and 
recorded compensation expense of approximately $728,000.  Additionally, in March 2007 the Company issued 1,250 shares
of stock to the senior executive as the Company reached certain performance levels.  The Company has recognized
approximately $136,000 of expense related to this issuance as of December 31, 2007. 

In February 2007, February 2006, and March 2005, the Company issued 78,657, 484,351, and 195,312 restricted stock
units, respectively, pursuant to the Company's restricted stock plan.  The total value of the issuances were 
$2.5 million, $16.4 million, and $4.5 million, 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 exchange for accounting 
purposes with a fair value assigned to this transaction of $11.5 million.

ST. MARY LAND & EXPLORATION COMPANY AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
DECEMBER 31, 2007 

Note 1 – Summary of Significant Accounting Policies 

Description of Operations 

St. Mary Land & Exploration Company (“St. Mary” or the "Company") is an independent energy company 
engaged in the exploration, exploitation, development, acquisition, and production of natural gas and crude oil.  The 
Company’s operations are conducted in the continental United States and offshore in the Gulf of Mexico. 

Basis of Presentation 

The accompanying consolidated financial statements include the accounts of the Company and its wholly-

owned subsidiaries.  Subsidiaries that are not wholly-owned are accounted for using full consolidation with minority 
interest or by the equity or cost method as appropriate.  Equity method investments are included in other noncurrent 
assets, and minority interest is included in other noncurrent liabilities in the accompanying consolidated balance 
sheets.  All significant intercompany accounts and transactions have been eliminated. 

Use of Estimates in the Preparation of Financial Statements 

The preparation of financial statements in conformity with accounting principles generally accepted in the 
United States requires management to make estimates and assumptions that affect the reported amounts of oil and 
gas reserves, assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial 
statements, and the reported amounts of revenues and expenses during the reporting period.  Actual results could 
differ from those estimates.  Estimates of oil and gas reserve quantities provide the basis for calculations of 
depletion, depreciation, and amortization (“DD&A”), impairment, goodwill, and the Net Profits Interest Bonus Plan 
(the “Net Profits Plan”) liability, each of which represents a significant component of the accompanying 
consolidated financial statements. 

Revenue Recognition 

The Company derives revenue primarily from the sale of produced natural gas and crude oil.  The Company 

reports revenue as the gross amount received before taking into account production taxes and transportation costs, 
which are reported as separate expenses.  Revenue is recorded in the month the Company’s production is delivered 
to the purchaser, but payment is generally received between 30 and 90 days after the date of production.  No revenue 
is recognized unless it is determined that title to the product has transferred to a purchaser.  At the end of each 
month, the Company estimates the amount of production delivered to the purchaser and the price the Company will 
receive.  The Company uses its knowledge of its properties, their historical performance, the anticipated effect of 
weather conditions during the month of production, New York Mercantile Exchange (“NYMEX”) and local spot 
market prices, and other factors as the basis for these estimates. 

Cash and Cash Equivalents 

The Company considers all liquid investments purchased with an initial maturity of three months or less to 

be cash equivalents.  The carrying value of cash and cash equivalents approximates fair value due to the short-term 
nature of these instruments. 

F-7 

 
Short-term Investments 

As of December 31, 2007, the Company’s short-term investments consist of a certificate of deposit.  As of 

December 31, 2006, the Company’s short-term investments consist of investment-grade marketable debt that is 
classified as held-to-maturity or available-for-sale.  Securities categorized as held-to-maturity are stated at 
amortized cost whereas available-for-sale securities are marked-to-market.  As of December 31, 2007, and 2006, 
the Company held $1.2 million and $1.5 million, respectively, of short-term investments. 

Concentration of Credit Risk 

Substantially all of the Company's receivables are within the oil and gas industry, primarily from purchasers 

of oil and gas and from partners with interests in common properties operated by the Company.  Although 
diversified among many companies, collectability is dependent upon the financial wherewithal of each individual 
company as well as the general economic conditions of the industry.  The receivables are not collateralized.  To date 
the Company has had minimal bad debts. 

The Company has accounts with separate banks in Denver, Colorado; Shreveport, Louisiana; Franklin, 
Louisiana; Tulsa, Oklahoma; and Billings, Montana.  At December 31, 2007, 2006, and 2005, the Company had 
$42.8 million, $1.6 million, and $36.8 million respectively, invested in money market funds and overnight 
investment sweep accounts.  The difference between the investment amount and the cash and cash equivalents 
amount on the accompanying consolidated balance sheets represents uncleared disbursements and non-interest 
bearing checking accounts.  The Company’s policy is to invest in highly-rated instruments and to limit the amount of 
credit exposure at each individual institution. 

The Company currently uses nine separate counterparties for its oil and gas commodity and interest rate 

derivatives.  The counterparties to the Company’s derivative instruments are all highly-rated entities with corporate 
credit ratings at or exceeding A- or A2 as classified by Standard & Poor’s and Moody’s respectively. 

Oil and Gas Producing Activities 

The Company follows the successful efforts method of accounting for its oil and gas properties.  Under this 
method of accounting, all property acquisition costs and costs of exploratory and development wells are capitalized 
when incurred, pending determination of whether the well has found proved reserves.  If an exploratory well does 
not find proved reserves, the costs of drilling the well are charged to expense.  Exploratory dry hole costs are 
included in cash flows from investing activities as part of capital expenditures within the accompanying consolidated 
statements of cash flows.  The costs of development wells are capitalized whether or not proved reserves are found.   

Geological and geophysical costs and the costs of carrying and retaining unproved properties are expensed 

as incurred.  DD&A of capitalized costs related to proved oil and gas properties is calculated on a field-by-field basis 
using the units-of-production method based upon proved reserves.  The computation of DD&A takes into 
consideration restoration, dismantlement, and abandonment costs and the anticipated proceeds from salvaging 
equipment.  As of December 31, 2007, the Company’s capitalized proved oil and gas properties included 
$95.9 million of estimated salvage value, which is excluded from the depletable property costs when calculating 
DD&A.   

The Company follows Statement of Financial Accounting Standards Staff Position No. FAS 19-1, 

“Accounting for Suspended Well Costs,” (“FSP FAS 19-1”).  For additional discussion, please see Note 13 – 
Disclosures about Oil and Gas Producing Activities under the heading Suspended Well Costs.   

The Company reviews its long-lived assets for impairments when events or changes in circumstances 

indicate that an impairment may have occurred.  The impairment test for proved properties compares the expected 
undiscounted future net cash flows on a field-by-field basis with the related net capitalized costs, including costs 
associated with asset retirement obligations, at the end of each period.  Expected future cash flows are calculated 
on all proved reserves using a discount rate and price forecasts selected by the Company’s management.  The 
discount rate is a rate that management believes is representative of current market conditions.  The price forecast 

F-8 

 
is based on NYMEX strip pricing, adjusted for basis differentials, for the first five years.  At the end of the first 
five years a flat terminal price is used.  Future operating costs are also adjusted as deemed appropriate for these 
estimates.  When the net capitalized costs exceed the undiscounted future net revenues of a field, the cost of the 
field is reduced to fair value, which is determined using discounted future net revenues.  An impairment write 
down is provided on unproved property when the Company determines that either the property will not be 
developed or the carrying value is not realizable. 

Sales of Proved and Unproved Properties 

The sale of a partial interest in a proved oil and gas property is accounted for as normal retirement, and no 

gain or loss is recognized as long as this treatment does not significantly affect the units-of-production depletion 
rate.  A gain or loss is recognized for all other sales of producing properties and is included in the results of 
operations. 

The sale of a partial interest in an unproved property is accounted for as a recovery of cost when substantial 
uncertainty exists as to recovery of the cost applicable to the interest retained.  A gain on the sale is recognized to the 
extent the sales price exceeds the carrying amount of the unproved property.  A gain or loss is recognized for all 
other sales of nonproducing properties and is included in the accompanying consolidated results of operations. 

Assets Held for Sale 

In accordance with Statement of Financial Accounting Standards No. 144, “Accounting for the Impairment 
or Disposal of Long-Lived Assets”, any properties held for sale as of the date of presentation of a balance sheet have 
been classified as assets held for sale and are separately presented on the accompanying consolidated balance sheets 
at the lower of net book value or fair value less the cost to sell.  The asset retirement obligation liabilities related to 
such properties have been reclassified to asset retirement obligation associated with oil and gas properties held for 
sale.  For additional discussion of assets held for sale, please see Note 3 – Acquisitions, Divestitures, and Assets 
Held for Sale. 

Other Property and Equipment 

Other property and equipment such as office furniture and equipment, automobiles, and computer hardware 
and software are recorded at cost.  Costs of renewals and improvements that substantially extend the useful lives of 
the assets are capitalized.  Maintenance and repair costs are expensed when incurred.  Depreciation is calculated 
using the straight-line method over the estimated useful lives of the assets from three to eight years.  When other 
property and equipment is sold or retired, the capitalized costs and related accumulated depreciation are removed 
from the accounts. 

Gas Balancing 

The Company uses the sales method of accounting for gas revenue whereby sales revenue is recognized on 

all gas sold to purchasers, regardless of whether the sales are proportionate to the Company’s ownership in the 
property.  An asset or a liability is recognized to the extent that there is an imbalance in excess of the remaining gas 
reserves on the underlying properties.  The Company’s gas imbalance position at December 31, 2007, and 2006, 
resulted in the recording of $1.9 million and $1.4 million, respectively, to accounts receivable, and $1.1 million and 
$791,000, respectively, to accounts payable. 

Derivative Financial Instruments 

The Company seeks to protect its rate of return on acquisitions of producing properties and other 
production by hedging cash flows.  The Company intends for derivative instruments used for this purpose to be 
designated as, and to qualify as, cash flow hedging instruments under Statement of Financial Accounting 
Standards No. 133, “Accounting for Derivative Instruments and Hedging Activities,” (“SFAS No. 133”) and 
related pronouncements.  The Company seeks to minimize basis risk and indexes the majority of its oil hedges to 
NYMEX prices and the majority of its gas hedges to various regional index prices associated with pipelines in 

F-9 

proximity to the Company's areas of gas production.  For additional discussion of derivatives, please see 
Note 10 – Derivative Financial Instruments. 

Fair Value of Financial Instruments 

The Company’s financial instruments including cash and cash equivalents, accounts receivable, and 

accounts payable are carried at cost, which approximates fair value due to the short-term maturity of these 
instruments.  The recorded value of the Company’s credit facility approximates its fair value as it bears interest at 
a floating rate.  The Company had $285.0 million in loans outstanding under its revolving credit agreement as of 
December 31, 2007, and $334.0 million in loans outstanding under its revolving credit agreement as of 
December 31, 2006.  The Company’s interest rate swaps are recorded at fair value as discussed in Note 10 – 
Derivative Financial Instruments.  The Company’s 3.50% Senior Convertible Notes due 2027 (the “3.50% Senior 
Convertible Notes”) are recorded at cost, and the fair value is disclosed in Note 5 – Long-Term Debt.  The 
Company has other financial instruments and investments in available-for-sale securities that are marked-to-
market for which changes in fair value are recorded in accumulated other comprehensive income in the 
accompanying consolidated balance sheets.  Since considerable judgment is required to develop estimates of fair 
value, the estimates provided are not necessarily indicative of the amounts the Company could realize upon the 
sale or refinancing of such instruments. 

Net Profits Plan 

The Company records the estimated fair value of the liability for future payments under the Net Profits Plan.  

The estimated liability is a discounted calculation and has underlying assumptions including estimates of oil and 
gas reserves, recurring and workover lease operating expense, production and ad valorem tax rates, present value 
discount factors, and pricing assumptions.  The estimates the Company uses in calculating the long-term liability 
are adjusted from period-to-period based on the most current information attributable to the underlying 
assumptions.  Changes in the estimated liability of future payments associated with the Net Profits Plan are 
recorded as increases or decreases to expense in the current period as a separate line item in the accompanying 
consolidated statements of operations as these changes are considered changes in estimates.  The estimated Net 
Profits Plan liability is recorded separately as a noncurrent liability in the accompanying consolidated balance 
sheets. 

The distribution amounts due to participants and payable in each period under the Net Profits Plan as cash 

compensation related to periodic operations are recognized as compensation expense and are included within general 
and administrative expense and exploration expense in the accompanying consolidated statements of operations.  
The corresponding current liability is included in accounts payable and accrued expenses in the accompanying 
consolidated balance sheets.  This treatment provides for a consistent matching of cash expense with net cash flows 
from the oil and gas properties in each respective pool of the Net Profits Plan.  For additional discussion, please see 
Note 7 – Compensation Plans under the heading Net Profits Plan. 

Income Taxes 

The Company accounts for deferred income taxes utilizing Statement of Financial Accounting Standards 
No. 109, “Accounting for Income Taxes,” ("SFAS No. 109") as amended.  SFAS No. 109 prescribes an asset and 
liability method whereby deferred tax assets and liabilities are recognized based on the tax effects of temporary 
differences between the carrying amount on the financial statements and the tax bases of assets and liabilities, as 
measured by current enacted tax rates.  These differences will result in taxable income or deductions in future years 
when the reported amount of the asset or liability is recovered or settled, respectively.  When appropriate, in 
accordance with SFAS No. 109, the Company evaluates the need for a valuation allowance to reduce deferred tax 
assets. 

F-10 

Earnings per Share 

Basic net income per common share of stock is calculated by dividing net income available to common 

stockholders by the weighted-average basic common shares outstanding for the respective period.  The shares 
represented by vested restricted stock units (“RSUs”) are included in the calculation of the weighted-average basic 
common shares outstanding.  The basic earnings per share calculations reflect the impact of any repurchases of 
shares of common stock made by the Company. 

Diluted net income per common share of stock is calculated by dividing adjusted net income by the 
weighted-average diluted common shares outstanding, which includes the effect of potentially dilutive securities.  
Potentially dilutive securities for the diluted earnings per share calculations consist of unvested RSUs, in-the-money 
outstanding stock options to purchase the Company’s common stock, shares into which the 5.75% Senior 
Convertible Notes due 2022 (the “5.75% Senior Convertible Notes”) were convertible for the periods those notes 
were outstanding, and shares into which the 3.50% Senior Convertible Notes due 2027 are convertible. 

The shares underlying the unvested grants of RSUs are included in the diluted earnings per share calculation 

beginning on the grant date of the RSUs.  Following the lapse of restriction periods, the shares underlying the units 
are issued and therefore are included in the number of issued and outstanding shares. 

The treasury stock method is used to measure the dilutive impact of stock options.  The following table 
details the weighted-average dilutive and anti-dilutive securities related to stock options and RSUs for the years 
presented:

Prior to the conversion of the Company’s 5.75% Senior Convertible Notes on March 16, 2007, potentially 

dilutive shares associated with this instrument were accounted for using the if-converted method for the 
determination of diluted earnings per share.  Adjusted net income used in the if-converted method was derived by 
adding interest expense paid on the 5.75% Senior Convertible Notes back to net income and then adjusting for 
nondiscretionary items that are based on net income and would have changed had the 5.75% Senior Convertible 
Notes been converted at the beginning of the period.  The 5.75% Senior Convertible Notes were called for 
redemption by the Company on March 16, 2007, and all of the note holders elected to convert the notes to shares of 
the Company’s common stock.  The Company issued 7.7 million common shares in connection with the conversion 
of the 5.75% Senior Convertible Notes.  Upon conversion, these shares were included in the calculation of weighted-
average common shares outstanding.  The diluted earnings per share calculation for the year ended 
December 31, 2007, was adjusted for the conversion and included a time-weighted average of approximately 
1.6 million potentially dilutive shares related to the 5.75% Senior Convertible Notes.  A total of 7.7 million 
potentially dilutive shares related to the 5.75% Senior Convertible Notes were included in the calculation of diluted 
earnings per share for the years ended December 31, 2006, and 2005.   

The Company’s 3.50% Senior Convertible Notes have a net-share settlement right, and the treasury stock 

method is used to measure the potentially dilutive impact of shares associated with that conversion feature.  The 
3.50% Senior Convertible Notes issued April 4, 2007 have not been dilutive for the entire time they have been 
outstanding and therefore do not impact the diluted earnings per share calculation for the period ended 
December 31, 2007. 

The dilutive impact of unvested RSUs and stock options is considered in the detailed calculations below.  

There were no anti-dilutive securities related to stock options or RSUs for the years ended December 31, 2005, 
2006, and 2007.

and stock options issued to employees and non-employee directors as more fully described in Note 7 – 
Compensation Plans.  Stock options were last issued in December 2004.  Prior to 2006, the Company had accounted 
for stock-based compensation using the intrinsic value recognition and measurement principles detailed in 
Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” ("APB Opinion No. 25") 
and related interpretations.  No stock-based employee compensation expense relating to stock options has been 
reflected in the Company’s accompanying consolidated statements of operations for any period presented prior to 
2006 since all options granted under the plans had an exercise price equal to the market value of the underlying 
common stock on the date of grant.  The Company used the Black-Scholes option valuation model to calculate the 
disclosures required under Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based 
Compensation” (“SFAS No. 123”).  Beginning January 1, 2006, the Company adopted the provisions of Statement 
of Financial Accounting Standards No. 123(R), “Share-Based Payment” (“SFAS No. 123(R)”).  This statement 
requires the Company to record expense associated with the fair value of stock-based compensation.  The total 
unrecognized compensation expense associated with unvested stock options at the date of adoption of this standard 
totaled $2.4 million.  The Company elected to use the modified-prospective adoption method for the standard and 
consequently recognized additional compensation expense of $1.9 million in 2006 and $437,000 in 2007, and 
expects to recognize expense of $17,000 in 2008 related to the vesting of these stock options.  The Company has 
recorded compensation expense associated with the issuance of RSUs since the plan was adopted in 2004 and units 
were first granted.  The Company recognizes costs associated with these grants based on the estimated fair value of 
the RSUs as determined at the time of the grant.

The following table illustrates the pro forma effect on net income and earnings per share if the Company 

had applied the fair value recognition provisions of SFAS No. 123 to stock-based employee compensation prior to 
the implementation of SFAS No. 123(R):

For purposes of pro forma disclosures, the estimated fair values of the options and employee stock 

purchase plan grants are amortized to expense over the options’ vesting periods.  The effects of applying 
SFAS No. 123 in the pro forma disclosure are not necessarily indicative of actual future amounts.  

Recently Issued Accounting Standards 

In December 2007 the FASB issued Statement of Financial Accounting Standards No. 141(R), “Business 
Combinations” (“SFAS No. 141(R)”), which requires the acquiring entity in a business combination to recognize 
and measure all assets and liabilities assumed in the transaction and any non-controlling interest in the acquiree at 
fair value as of the acquisition date.  SFAS No. 141(R) also establishes guidance for the measurement of the 
acquirer shares issued in consideration for a business combination, the recognition of contingent consideration, 
the accounting treatment for pre-acquisition gain and loss contingencies, the treatment of acquisition related 
transaction costs, and the recognition of changes in the acquirer's income tax valuation allowance and deferred 
taxes.  SFAS No. 141(R) is effective for fiscal years beginning after December 15, 2008, and is to be applied 
prospectively as of the beginning of the fiscal year in which the statement is applied.  Early adoption is not 
permitted. SFAS No. 141(R) will be effective for the Company beginning with the 2009 fiscal year.  The 
Company is currently evaluating the impact of SFAS No. 141(R) on its accompanying consolidated financial 
statements when effective, but the nature and magnitude of the specific effects will depend upon the nature, terms, 
and size of the acquisitions the Company consummates after the effective date.   

In December 2007 the FASB issued Statement of Financial Accounting Standards No. 160, 

“Noncontrolling Interests in Consolidated Financial Statements – an amendment of ARB 51” (“SFAS No. 160”), 
which establishes accounting and reporting standards that require noncontrolling interests to be reported as a 
component of equity.  SFAS No. 160 also requires that changes in a parent's ownership interest while the parent 
retains its controlling interest be accounted for as equity transactions and that any retained noncontrolling equity 
investment upon the deconsolidation of a subsidiary be initially measured at fair value.  SFAS No. 160 is effective 
for fiscal years beginning after December 15, 2008, and is to be applied prospectively as of the beginning of the 
fiscal year in which the statement is applied.  The Company is required to adopt SFAS No. 160 beginning with 
the 2009 fiscal year.  The Company is currently evaluating the potential impact, if any, of the adoption of 
SFAS No. 160 on its accompanying consolidated financial statements when effective.

In February 2007 the FASB issued Statement of Financial Accounting Standards No. 159, “The Fair 

Value Option for Financial Assets and Financial Liabilities” (“SFAS No. 159”), which expands the use of fair 
value accounting but does not affect existing standards that require assets or liabilities to be carried at fair value.  
SFAS No. 159 allows entities to choose, at specified election dates, to use fair value to measure eligible financial 
assets and liabilities that are not otherwise required to be measured at fair value.  If a company elects the fair 
value option for an eligible item, changes in that item's fair value in subsequent reporting periods must be 
recognized in current earnings.  SFAS No. 159 also establishes presentation and disclosure requirements designed 
to draw comparisons between entities that elect different measurement attributes for similar assets and liabilities.  
If elected, SFAS No. 159 is effective for fiscal years beginning after November 15, 2007.  SFAS No. 159 will be 
effective for the Company beginning with the 2008 fiscal year.  The Company did not elect the fair value option.  
There is no impact on the Company’s consolidated financial statements.  

In September 2006 the FASB issued Statement of Financial Accounting Standards No. 157, “Fair Value 

Measurements” (“SFAS No. 157”), which defines fair value, establishes a framework for measuring fair value, 
and expands disclosures about fair value measurements.  The provisions of SFAS No. 157 will be effective as of 
the beginning of the Company’s 2008 fiscal year.  The adoption of SFAS No. 157 has no impact on the 
Company’s consolidated financial statements, however, it will require changes in certain disclosures.  

Comprehensive Income 

Comprehensive income consists of net income, the unrealized gain or loss for the effective portion of 

derivative instruments classified as cash flow hedges, and the accrued pension benefit obligation in excess of plan 
assets.  Comprehensive income is presented net of income taxes in the accompanying consolidated statements of 
stockholders’ equity and comprehensive income.

Major Customers 

During 2007 and 2006 no customer individually accounted for more than ten percent of the Company’s total 
oil and gas production revenue.  During 2005 one customer individually accounted for 13 percent of the Company’s 
total oil and gas production revenue.   

Industry Segment and Geographic Information 

The Company operates in one industry segment, which is the exploration, exploitation, development, 
acquisition, and production of natural gas and crude oil.  All of the Company’s operations are conducted in the 
continental United States and the Gulf of Mexico.  Consequently, the Company currently reports as a single industry 
segment.  The Company’s gas marketing department provides mostly internal services, acting as a first purchaser of 
natural gas and natural gas liquids produced by the Company and as such the majority of the Company’s marketing 
activity is eliminated in consolidation.  The small amount of third-party income these operations generate is not 
material to the Company’s financial position, and segmentation of such net income would not provide a better 
understanding of the Company’s performance.  However, gross revenue and expense related to gas marketing 
operations are presented discreetly in the accompanying consolidated statements of operations. 

Intangible Assets 

As of December 31, 2007, and 2006, the Company’s accompanying consolidated balance sheets include 
$2.4 million and $3.4 million, respectively, of intangible assets.  These assets arise from acquired oil and gas sale 
contracts with favorable pricing terms.  They do not qualify as derivatives or hedges under SFAS No. 133.  
Intangible assets of the Company are amortized using the units-of-production method and are evaluated for 
impairment if such indicators arise.  Intangible assets are included in other noncurrent assets on the Company’s 
accompanying consolidated balance sheets. 

Goodwill  

Goodwill is measured as the excess of the acquisition costs over the sum of the amounts assigned to the 

identifiable assets acquired less liabilities assumed.  Goodwill was recorded as a result of the acquisition of Agate 
Petroleum, Inc. in January 2005.  Goodwill is reviewed for impairment annually or more frequently if impairment 
indicators arise.  The goodwill review is conducted at the reporting unit level.  A reporting unit is defined as the oil 
and gas properties in a region. 

Off – Balance Sheet Arrangements  

As part of its ongoing business, the Company has not participated in transactions that generate 
relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured 
finance or special purpose entities ("SPEs"), which would have been established for the purpose of facilitating 
off-balance sheet arrangements or other contractually narrow or limited purposes.  As of and up to 
December 31, 2007, the Company has not been involved in any unconsolidated SPE transactions. 

The Company evaluates its transactions to determine if any variable interest entities exist.  If it is 

determined that St. Mary is the primary beneficiary of a variable interest entity, that entity is consolidated into 
St. Mary.

Note 3 – Acquisitions, Divestitures, and Assets Held for Sale 

Rockford Acquisition 

On October 4, 2007, the Company completed the purchase of certain oil and gas properties in the Gold 
River project area targeting the Olmos shallow gas formation located primarily in Webb and Dimmit Counties, 
Texas.  The assets were purchased from Rockford Energy Partners II, LLC for $148.9 million of cash, which is 
net of normal purchase price adjustments of $2.1 million.  The acquisition was funded with cash on hand and 
borrowings under the Company’s existing revolving credit facility.  The Company allocated $127.2 million to 
proved oil and gas properties, $23.1 million to unproved oil and gas properties, and a net $292,000 to other assets.  
The Company also recorded $1.7 million in asset retirement obligation liability associated with the acquired 
properties. This property acquisition is adjacent to the recently acquired Catarina project area discussed below.  
The Company has hedged the equivalent of the first three years of natural gas production and the first two years 
of associated natural gas liquids production related to this acquisition.

Variable Interest Entity  

The acquisition of the properties in the Gold River project area was structured to qualify as the first step 

of a reverse like-kind exchange under Section 1031 of the Internal Revenue Code of 1986, as amended ("the 
IRC"), and I.R.S. Revenue Procedure 2000-37.  Prior to closing on the Rockford acquisition, the Company 
assigned all of its rights and duties under the purchase and sale agreement to NBF Reverse Exchange, LLC, an 
indirect wholly-owned subsidiary of Comerica Incorporated, which further assigned all of its rights and duties 
under the purchase and sale agreement to St. Mary Land & Exploration Acquisition, LLC (“SMLEA, LLC”), a 
company unaffiliated with St. Mary.  The Gold River assets were acquired by NBF Reverse Exchange, LLC as an 
exchange accommodation titleholder.  SMLEA, LLC held the assets pursuant to a qualified exchange 
accommodation agreement until the second step of the like-kind exchange was completed in conjunction with the 
divestiture of certain non-core oil and gas properties discussed below under Assets Held for Sale.  As of the date 
of closing on October 4, 2007, the assets held by SMLEA, LLC, were leased by St. Mary under a triple net lease 
whereby St. Mary enjoyed the benefits and risks of all revenues and costs attributed to the properties.  The Gold 
River assets were managed by St. Mary under the terms of a management agreement with SMLEA, LLC. 

In connection with the reverse like-kind exchange described above, St. Mary loaned an amount equal to 

the purchase price of the assets to SMLEA, LLC.  Based on the provisions of FASB Interpretation No. 46(R), 
“Consolidation of Variable Interest Entities”, the Company determined that SMLEA, LLC is a variable interest 
entity for which St. Mary is the primary beneficiary.  Accordingly, SMLEA, LLC was consolidated into St. Mary 
subsequent to the completion of the purchase of oil and gas properties on October 4, 2007.  As a result of the 
consolidation, St. Mary recognized all oil and gas reserves and production as well as all revenues and expenses 
attributed to the Rockford acquisition beginning on October 4, 2007. 

Catarina Acquisition 

On June 1, 2007, the Company acquired oil and gas properties located primarily in the Catarina project 

area in Webb County, Texas in exchange for $30.0 million of cash.  The Company allocated $29.9 million to 
proved oil and gas properties, $535,000 to unproved oil and gas properties, and a net $215,000 to other assets.  
The Company also recorded $623,000 in asset retirement obligation liability associated with the acquired 
properties.  The acquisition was funded with cash on hand and borrowings under the Company’s existing credit 
facility. 

Permian Basin Acquisition  

On December 14, 2006, the Company acquired oil and gas properties in the Permian Basin in West Texas 
from private parties in exchange for $243.1 million of cash, which is net of normal purchase price adjustments of 
approximately $4.3 million.  The Company recorded $199.1 million to proved oil and gas properties, 
$41.5 million to unproved oil and gas properties, $3.0 million to intangible assets, a net $326,000 to other assets, 
and $859,000 to asset retirement obligation liability.  The Company allocated the purchase price based on the 
estimated fair value of the assets and liabilities acquired.  The acquisition was accounted for using the purchase 
method and was funded with cash on hand and borrowings under the Company’s credit facility. 

Richland County, Montana Acquisition 

On May 15, 2006, the Company closed on a transaction whereby it exchanged oil and gas properties 

located in the Uinta Basin of Utah for oil and gas properties located in Richland County, Montana.  The 
transaction was structured to qualify as a like-kind exchange under Section 1031 of the Internal Revenue Code of 
1986, as amended, and I.R.S. Revenue Procedure 2000-37.  For financial reporting purposes, the transaction is 
considered a non-monetary exchange and was accounted for at estimated fair value.  The exchange of properties 
resulted in recognition of approximately $6.4 million of gain. 

F-17 

Assets Held for Sale 

In December 2007 St. Mary reached an agreement for the sale of its previously announced divestiture 
package, and on January 31, 2008, the Company completed the divestiture of certain non-strategic oil and gas 
properties located primarily in the Rocky Mountain and Mid-Continent regions to Abraxas Petroleum Corporation 
and Abraxas Operating, LLC.  The cash received at closing before commission costs was $131.1 million.  The final 
sale price is subject to normal post-closing adjustments and settlements and is expected to be finalized during the 
second quarter of 2008.  The transaction has an effective date of December 1, 2007.  The accompanying 
consolidated balance sheet as of December 31, 2007, presents the $76.9 million assets held for sale, net of 
accumulated depletion, depreciation and amortization.  The corresponding asset retirement obligation of $8.7 million 
and a $10.0 million deposit associated with oil and gas properties held for sale are also separately presented.  Under 
FASB Emerging Issues Task Force Issue No. 03-13, the Company determined that these sales do not qualify for 
discontinued operations accounting.

At December 31, 2007, the Company had estimated state net operating loss carryforwards of approximately 

$162.5 million that expire between 2008 and 2027 and state tax credits of $145,000 that expire between 2008 and 
2016.  A portion of the Company’s valuation allowance relates to state net operating loss carryforwards, state tax 
credits, and state and federal income tax benefit amounts that the Company anticipates will expire before they can be 
utilized.  The Company has concluded that permanent items included in the calculation of income tax for certain 
states may impact its ability to deduct net operating losses and realize federal income tax deduction benefits of those 
states and has adjusted its valuation allowances accordingly.  The remaining portion of the valuation allowance 
relates to the Net Profits Plan liability and reflects an estimate of future executive compensation that may not be 
deductible for income tax purposes when future cash payments occur under the plan.

Acquisitions, drilling, and basis differentials impacting the prices received for crude oil and natural gas, 

affect the apportionment of taxable income to the states where the Company owns properties.  As these factors 
change, the Company’s blended state income tax rate changes.  This change applied to the Company’s total 
temporary differences will impact the total income tax reported in the current year and is reflected in state taxes in 
the table above.  Items affecting state apportionment factors are evaluated upon completion of the prior year 
income tax return and after significant acquisitions are closed during the current year. 

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and in various 
states.  With few exceptions, the Company is no longer subject to U.S. federal or state income tax examinations 
by these tax authorities for years before and including 2003.  The Internal Revenue Service completed audits for 
the 2000, 2002, and 2003 tax years during the quarter ended March 31, 2007.  There was no change to the 
provision for income tax as a result of these examinations. 

In the third quarter of 2007 the Company received a refund of income tax and interest of $3.1 million 

from a carryback of net operating losses to the 2000 tax year.  An additional $1.0 million due to the Company for 
income tax refunds and accrued interest resulting from a carry over of minimum tax credits to the 2003 tax year 
was received in January 2008.  These amounts have been previously recognized by the Company. 

The Company adopted the provisions of FASB Interpretation No. 48, "Accounting for Uncertainty in 

Income Taxes" (“FIN No. 48”), on January 1, 2007.  There was no financial statement adjustment required as a 
result of adoption.  At adoption, the Company had a long-term liability for unrecognized tax benefit of 
$1.0 million and accumulated interest liability of $92,000.  The entire amount of unrecognized tax benefit would 
affect the Company’s effective tax rate if recognized.  Interest expense in the 2007 accompanying consolidated 
statements of operations includes a nominal $4,000 associated with income tax.  Penalties associated with income 
tax are recorded in general and administrative expense in the accompanying consolidated statements of 
operations.  There were no penalties associated with income tax recorded for the year ended December 31, 2007.

Note 5 – Long-term Debt  

Revolving Credit Facility 

The Company’s revolving credit facility specifies a maximum loan amount of $500 million and has a 

maturity date of April 7, 2010.  Borrowings under the facility are secured by a pledge in favor of the lenders of 
collateral that includes the majority of the Company’s oil and gas properties and the common stock of the material 
subsidiaries of the Company.  The borrowing base under the credit facility as authorized by the bank group as of 
the date of this filing is $1.25 billion and is subject to regular semi-annual redeterminations.  The borrowing base 
redetermination process considers the value of St. Mary’s oil and gas properties and other assets, as determined by 
the bank syndicate.  The Company has elected an aggregate commitment amount of $500 million under the credit 
facility.  The Company must comply with certain financial and non-financial covenants under its existing credit 
facility.  The Company is in compliance with all covenants associated with the credit facility.  The payment of 
dividends is subject to covenants under the Company’s existing credit facility, including the requirement that the 
Company maintain certain levels of stockholders’ equity and the limitation of the Company’s annual dividend rate to 
no more than $0.25 per share per year.  Interest and commitment fees are accrued based on the borrowing base 
utilization percentage table below.  Euro-dollar loans accrue interest at London Interbank Offered Rate 
(“LIBOR”) plus the applicable margin from the utilization table, and Alternative Base Rate (“ABR”) loans accrue 
interest at Prime plus the applicable margin from the utilization table.  Commitment fees are accrued on the 
unused portion of the aggregate commitment amount and are included in interest expense in the accompanying 
consolidated statements of operations.

5.75% Senior Convertible Notes Due 2022 

The Company called for redemption of its 5.75% Senior Convertible Notes on March 16, 2007.  The call 
for redemption resulted in the note holders electing to convert the notes to common stock in accordance with the 
conversion provision in the original indenture.  The 5.75% Convertible Note holders converted all $100 million of 
the 5.75% Senior Convertible Notes to common shares at a conversion price of $13.00 per share.  The Company 
issued 7.7 million common shares in connection with the conversion. 

3.50% Senior Convertible Notes Due 2027 

On April 4, 2007, the Company issued $287.5 million aggregate principal amount of 3.50% Senior 
Convertible Notes.  The 3.50% Senior Convertible Notes mature on April 1, 2027, unless earlier converted, 
redeemed, or purchased by the Company. The 3.50% Senior Convertible Notes are unsecured senior obligations 

F-21 

 
 
 
 
 
 
and rank equal in right of payment with all of the Company’s existing and any future unsecured senior debt and 
senior in right of payment to any future subordinated debt. 

Holders may convert their notes based on a conversion rate of 18.3757 shares of the Company’s common 
stock per $1,000 principal amount of the 3.50% Senior Convertible Notes (which is equal to an initial conversion 
price of approximately $54.42 per share), subject to adjustment, contingent upon and only under the following 
circumstances: (1) if the closing price of the Company's common stock reaches specified thresholds or the trading 
price of the notes falls below specified thresholds, (2) if the notes are called for redemption, (3) if specified 
distributions to holders of the Company’s common stock are made or specified corporate transactions occur, (4) if 
a fundamental change occurs, or (5) during the ten trading days prior to, but excluding, the maturity date.  The 
notes and underlying shares have been registered under a shelf registration statement.  If the Company becomes 
involved in a material transaction or corporate development, it may suspend trading of the 3.50% Senior 
Convertible Notes under the prospectus.  In the event the suspension period exceeds 45 days within any three-
month period or 90 days within any twelve-month period, the Company will be required to pay additional interest 
to all holders of the 3.50% Senior Convertible Notes, not to exceed a rate per annum of 0.50 percent of the issue 
price of the 3.50% Senior Convertible Notes; provided that no such additional interest shall accrue after 
April 4, 2009. 

Upon conversion of the 3.50% Senior Convertible Notes, holders will receive cash or common stock, or 

any combination thereof as elected by the Company.  At any time prior to the maturity date of the notes, the 
Company has the option to unilaterally and irrevocably elect to settle its obligations upon conversion of the notes 
in cash and, if applicable, shares of common stock.  If the Company makes this election, then, for each $1,000 
principal amount of notes converted, the Company will pay the following to holders in lieu of shares of common 
stock: (1) an amount in cash equal to the lesser of (i) $1,000 or (ii) the conversion value determined in the manner 
set forth in the indenture for the 3.50% Senior Convertible Notes, and (2) if the conversion value exceeds $1,000, 
the Company will also deliver, at its election, cash or common stock or a combination of cash and common stock 
with respect to the remaining value deliverable upon conversion.  Currently, it is the Company’s intention to net 
share settle the 3.50% Senior Convertible Notes.  However, the Company has not made this a formal legal 
irrevocable election and thereby reserves the right to settle the 3.50% Senior Convertible Notes in any manner 
allowed under the offering memorandum as business conditions warrant. 

If a holder elects to convert its notes in connection with certain events that constitute a change of control 

before April 1, 2012, the Company will pay, to the extent described in the related indenture, a make-whole 
premium by increasing the conversion rate applicable to the 3.50% Senior Convertible Notes.  In addition, the 
Company will pay contingent interest in cash, commencing with any six-month period beginning on or after 
April 1, 2012, if the average trading price of a note for the five trading days ending on the third trading day 
immediately preceding the first day of the relevant six-month period equals 120 percent or more of the principal 
amount of the 3.50% Senior Convertible Notes. 

On or after April 6, 2012, the Company may redeem for cash all or a portion of the 3.50% Senior 
Convertible Notes at a redemption price equal to 100 percent of the principal amount of the notes to be redeemed 
plus accrued and unpaid interest, if any, up to but excluding, the applicable redemption date.  Holders of the 
3.50% Senior Convertible Notes may require the Company to purchase all or a portion of their notes on each of 
April 1, 2012, April 1, 2017, and April 1, 2022, at a purchase price equal to 100 percent of the principal amount 
of the notes to be repurchased plus accrued and unpaid interest, if any, up to but excluding the applicable purchase 
date.  On April 1, 2012, the Company may pay the purchase price in cash, in shares of common stock, or in any 
combination of cash and common stock.  On April 1, 2017, and April 1, 2022, the Company must pay the 
purchase price in cash.  Based on the market price of the 3.50% Senior Convertible Notes, the estimated fair value 
of the notes was approximately $296 million as of December 31, 2007. 

In August 2007 the FASB proposed FASB Staff Position APB 14-a, “Accounting for Convertible Debt 

Instruments That May Be Settled in Cash Upon Conversion (including Partial Cash Settlement)” (“FSP  
APB 14-a”).  FSP APB 14-a proposes that the accounting treatment for certain convertible debt instruments that 
may be settled in cash, shares of common stock, or any portion thereof at the election of the issuing company be 
accounted for utilizing a bifurcation model under which the value of the debt instrument would be determined 

F-22 

without regard to the conversion feature.  As of the date of this filing, FSP APB 14-a remains a proposed FASB 
staff position under redeliberation. 

Weighted-Average Interest Rate Paid and Capitalized Interest 

The weighted-average interest rate paid in 2007, 2006, and 2005 was 5.4 percent, 7.6 percent, and 

7.1 percent, respectively, including commitment fees paid on the unused portion of the credit facility aggregate 
commitment, amortization of deferred financing costs, amortization of the contingent interest embedded derivative 
associated with the 5.75% Senior Convertible Notes, and the effect of interest rate swaps.  The average outstanding 
loan balance in 2007 grew at a faster rate than the aforementioned items resulting in a lower weighted-average 
interest rate.  Capitalized interest costs for the Company for the years ended December 31, 2007, 2006, and 2005, 
were $5.4 million, $3.5 million, and $1.9 million, respectively.  

Note 6 – Commitments and Contingencies 

The Company has entered into various operating leases, some of which include drilling rig contracts of, 

approximately $25.5 million, office space leases of approximately $14.1 million, and compressor contracts of 
approximately $2.0 million.  The annual minimum lease payments for the next five years and thereafter are 
presented below:

The Company leases office space under various operating leases with terms extending as far as 
May 31, 2014.  Rent expense, net of sublease income, was $1.9 million, $1.5 million, and $1.3 million in 2007, 
2006, and 2005, respectively.  The Company also leases office equipment under various operating leases.  The 
Company has a non-cancelable sublease through May 2012, of approximately $816,000, with payments of $185,000 
per year through 2011 and $77,000 in 2012. 

The Company is subject to litigation and claims that have arisen in the ordinary course of business.  The 

Company accrues for such items when a liability is both probable and the amount can be reasonably estimated.  In 
the opinion of management, the results of such litigation and claims will not have a material effect on the results of 
operations, the financial position, or cash flows of the Company.  Management believes it has sufficiently provided 
for such items to the extent necessary in the consolidated balance sheets. 

Note 7 – Compensation Plans 

Cash Bonus Plan 

The Company has a cash bonus plan under which the Company can award participants a cash bonus of up to 

50 percent of their aggregate base salary.  Any awards under the cash bonus plan are based on Company and 
regional performance, and then are further refined by individual performance.  The Company accrues cash bonus 
expense related to the current year’s performance.  Included in the general and administrative and exploration 
expense line items in the accompanying consolidated statements of operations are $3.6 million, $1.9 million, and 
$7.4 million of cash bonus expense related to the specific performance year for the years ended December 31, 2007, 
2006, and 2005, respectively.

Net Profits Plan 

Under the Company’s Net Profits Plan, all oil and gas wells that are completed or acquired during a year 

are designated within a specific pool.  Key employees recommended by senior management and designated as 
participants by the Company’s Compensation Committee of the Board of Directors and employed by the 
Company on the last day of that year become entitled to payments under the Net Profits Plan after the Company 
has received net cash flows returning 100 percent of all costs associated with that pool.  Thereafter, ten percent of 
future net cash flows generated by the pool are allocated among the participants and distributed at least annually.  
The portion of net cash flows from the pool to be allocated among the participants increases to 20 percent after the 
Company has recovered 200 percent of the total costs for the pool, including payments made under the Net Profits 
Plan at the ten percent level.  The Net Profits Plan has been in place since 1991.  Pool years prior to and including 
2005 are fully vested.  The 2006 and 2007 Pool years carry a vesting period of three years, whereby one-third is 
vested at the end of the year for which participation is designated and one-third vests on each of the following two 
anniversary dates.  The 2006 and 2007 Pool years include a cap whereby the maximum benefit to full participants 
from a particular year’s pool is limited to 300 percent of a participating individual’s adjusted base salary paid 
during the year to which the pool relates.  In December 2007 the Board approved a restructuring of the 
Company’s incentive compensation programs.  The change in the incentive compensation structure is designed to 
replace the current programs involving the grant of RSUs and the grant of participation interests in the Net Profits 
Plan with a single long-term incentive program utilizing performance shares.  As a result, the 2007 Net Profits 
Plan pool will be the last pool established by the Company.  

The Company records the estimated fair value of the long-term liability for estimated future payments 

under the Net Profits Plan based on the discounted value of estimated future payments associated with each 
individual pool.  The calculation of this liability is a significant management estimate.  Historically and for a 
predominate number of the pools, a discount rate of 15 percent was used to calculate this liability and is intended 
to represent the best estimate of the present value of expected future payments under the Net Profits Plan.  During 
the fourth quarter of 2007, the Company adjusted the discount rate used to calculate the present value of future 
payments from a base rate of 15 percent to 12 percent.  The decrease in the discount rate to 12 percent was based 
on experience gained from the divestiture marketing process, an overall sense of the valuation of oil and gas 
assets and an assessment of the current market for proved oil and gas reserves.   

The Company’s estimate of its liability is highly dependent on the price and cost assumptions, as well as 
the discount rates used in the calculations.  The commodity price assumptions are formulated by applying a price 
that is derived from a rolling average of actual prices realized over the prior 24 months together with adjusted 
NYMEX strip prices for the ensuing 12 months for a total of 36 months of data.  This average is adjusted to 
include the effect of hedge prices for the percentage of forecasted production hedged in the relevant period.  The 
forecasted non-cash expense associated with this significant management estimate is highly volatile from period 
to period due to fluctuations that occur in the crude oil and natural gas commodity markets.  Higher commodity 
prices experienced in recent years have moved more pools into payout status.  The Company continually 
evaluates the assumptions used in this calculation in order to include the current market environment for oil and 
gas prices, costs, discount rates, and overall market conditions.   

No published market quotes exist on which to base the Company’s estimate of fair value of the Net 

Profits Plan.  As such, it is entirely based on management estimates which are described within this footnote.  
While some inputs to the Company’s calculation to estimate the fair value of the Net Profits Plan’s future 
payments are from published sources, others are derived from the Company’s own calculations and estimates, 
such as the approximated discount rate and the expected future cash flows. 

F-24 

The following table presents the changes in the estimated future liability attributable to the Net Profits 

Plan.  These amounts relate to the realized results for the years presented from oil and gas operations for the 
properties associated with the respective pools that have achieved payout status.

The calculation of the estimated liability for the Net Profits Plan is highly sensitive to price estimates and 
discount rate assumptions.  For example, if the commodity prices used in the calculation changed by five percent, 
the liability recorded at December 31, 2007, would differ by approximately $19 million.  A one percentage point 
decrease in the discount rate would result in an increase to the liability of approximately $12 million.  While a 
one percentage point increase in the discount rate would result in a decrease to the liability of approximately 
$10 million.  Actual cash payments to be made to participants in future periods are dependent on realized actual 
production, prices, and costs associated with the properties in each individual pool of the Net Profits Plan.  
Consequently, actual cash payments will be inherently different from the amounts estimated. 

The Company records changes in the present value of estimated future payments under the Net Profits Plan 
as a separate item in the accompanying consolidated statements of operations.  The change in the estimated liability 
is recorded as a non-cash expense or benefit in the current period.  The amount recorded as an expense or benefit 
associated with the change in the estimated liability is not allocated to general and administrative expense or 
exploration expense because it is associated with the future net cash flows from oil and gas properties in the 
respective pools rather than results realized in the current period.  The table below presents the estimated allocation 
of the change in the liability if the Company did allocate the adjustment to these specific functional line items based 
on the current allocation of actual distributions being made by the Company.  The change in allocation of costs to 
the functional classification relates to the current composition of employees as compared to those individuals that 
have terminated employment with the Company.  For the years ended December 31, 2007, 2006, and 2005, 
22 percent, 54 percent, and 51 percent, respectively, of payments made under the Net Profits Plan were classified as 
exploration expense in the accompanying consolidated statements of operations.  As time progresses, less of the 
distribution relates to prospective exploration efforts as more of the distributions are made to employees that have 
terminated employment and thereby do not provide any period exploration support.

The Company has a defined contribution pension plan (the "401(k) Plan") that is subject to the Employee 

Retirement Income Security Act of 1974.  The 401(k) Plan allows eligible employees to contribute up to 60 percent 
of their base salaries.  The Company matches each employee's contributions up to six percent of the employee's base

were $1.5 million, $1.2 million, and $966,000 for the years ended December 31, 2007, 2006, and 2005, respectively.  
No discretionary contributions were made by the Company to the 401(k) Plan in any of these years. 

Employee Stock Purchase Plan 

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 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 IRC.  The Company 
has set aside 2,000,000 shares of its common stock to be available for issuance under the ESPP, of which 
1,599,811 shares are available for issuance as of December 31, 2007.  Shares issued under the ESPP totaled 
29,534 in 2007, 26,046 in 2006, and 28,447 in 2005.  Total proceeds to the Company for the issuance of these 
shares were $919,000 in 2007, $814,000 in 2006, and $601,000 in 2005.   

The fair value of ESPP shares are measured at the date of grant using the Black-Scholes option-pricing 

model.  The fair values of ESPP shares issued were estimated using the following weighted-average assumptions:

For the ESPP offering periods during 2007 and 2006, the Company expensed $260,000 and $243,000, 
respectively, based on the estimated fair values of grants on the respective grant dates.  There was no expense 
related to ESPP shares recorded in 2005. 

Equity Incentive Compensation Plan 

There are several components to the equity compensation plan that are described in this section.  Various 

types of equity awards have been granted by the Company in different periods.  For example, the Company 
ceased issuing stock options and began issuing restricted stock or RSUs to employees and directors in 2004.  
These disclosures reflect the culmination of the disclosure requirements for all equity awards still outstanding. 

In May 2006 the stockholders approved the 2006 Equity Incentive Compensation Plan (the “2006 Equity 

Plan”) to authorize the issuance of restricted stock, RSUs, 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 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. 

Effective January 1, 2006, the Company adopted SFAS No. 123(R) using the modified-prospective 

transition method.  Under that transition method, compensation expense recognized in 2006 and 2007 includes: 
(a) compensation cost for all share-based payments granted prior to, but not yet vested as of January 1, 2006, 
based on the grant date fair value estimated in accordance with the original provisions of SFAS No. 123, and 

F-26 

 
 
 
 
 
 
 
(b) compensation cost for all share-based payments granted subsequent to January 1, 2006, based on the grant 
date fair value estimated in accordance with the provisions of SFAS No. 123(R).   

As of December 31, 2007, 2.6 million shares of common stock remained available for grant under the 

2006 Equity Plan.  Any issuance of a direct share benefit such as an outright grant of common stock, a grant of a 
restricted share, or a RSU counts as two shares for each share issued against the amount eligible to be granted 
under the 2006 Equity Plan.  Each stock option and similar instrument granted counts as one share for each share 
issued against the eligible shares authorized to be issued under the 2006 Equity Plan. 

St. Mary anticipates granting Performance Share Plan (“PSP”) awards in lieu of RSUs beginning in 2008.  

The performance shares are expected to be subject to vesting periods and pre-established performance criteria.  
PSP awards will result in tradable shares of St. Mary common stock being issued immediately upon final vesting 
at the end of the planned three-year performance measurement period.  The Company expects that awards granted 
under the PSP will be granted under the existing stockholder approved 2006 Equity Plan.  The Company does 
have outstanding stock option grants under the Predecessor Plans and RSU grants under the Predecessor Plans 
and the 2006 Equity Plan.  The following sections describe the details of RSU grants and stock options 
outstanding as of December 31, 2007. 

Restricted Stock Incentive Program Under the Equity Incentive Compensation Plan 

The Company has a long-term incentive program whereby grants of restricted stock or RSUs have been 

awarded to eligible employees, consultants, and members of the Board of Directors.  Restrictions and vesting 
periods for the awards are determined at the discretion of the Board of Directors and are set forth in the award 
agreements.  Each RSU represents a right for one share of the Company’s common stock to be delivered upon 
settlement of the award at the end of a specified period.  These grants are determined annually based on a formula 
consistent with the cash bonus plan. 

St. Mary issued 78,657 RSUs on February 28, 2007, related to 2006 performance, 484,351 RSUs on 

February 28, 2006, related to 2005 performance and 195,312 RSUs on March 15, 2005 related to 2004 
performance.  The total fair value associated with these issuances was $2.5 million in 2007, $16.4 million in 2006, 
and $4.5 million in 2005 as measured on the respective grant dates.  The granted RSUs vest 25 percent 
immediately upon grant and 25 percent on each of the next three anniversary dates of the grant.  Compensation 
expense is recorded monthly over the vesting period of the award.  Vested shares of common stock underlying the 
2005 RSU grant will be issued on the third anniversary of the grant, at which time the shares carry no further 
restrictions.  For all awards subsequent to the 2005 RSU grant, St. Mary has eliminated the restriction period that 
extends beyond the vesting period so that shares will be issued without restriction upon vesting, rather than on the 
third anniversary of the award.  This change was effected within the safe harbor adoption provisions of the newly 
enacted U.S. Treasury regulations interpreting IRC laws governing deferred compensation.  The mutual election 
of the employee and the Company were required to effect this change.  Essentially all of the awards were 
modified for this mutual election and as such the incremental value associated with removing this restriction 
period will be amortized over the remaining service period for these awards.  For grants made beginning with the 
2006 grant period, the Company is using the accelerated amortization method as described in FASB Interpretation 
No. 28, “Accounting for Stock Appreciation Rights and Other Variable Stock Option or Award Plans – an 
interpretation of APB Opinions No. 15 and 25,” whereby approximately 48 percent of the total estimated 
compensation expense is recognized in the first year of the vesting period.  Expense for grants made for plan years 
prior to 2006 is being amortized under the straight-line method since this method was allowed prior to the 
adoption of SFAS No. 123(R).  As of December 31, 2007, a total of 684,264 RSUs were outstanding, of which 
394,879 were vested.  Total compensation expense related to the RSUs recognized in the year ended 
December 31, 2007, was $8.4 million.  This amount includes $2.8 million of compensation expense related to the 
2007 equity plan year for vesting of the estimated value of grants expected to be issued in 2008.  

St. Mary also issued 23,977 RSUs and 13,500 RSUs for various grants to specific employees during 2007 
and 2006, respectively.  No special grants were issued during 2005.  These grants have various vesting schedules.  
The fair value of these awards will be recorded to compensation expense over the respective vesting periods using 
the same basic framework as described above. 

F-27 

In 2007, 2006, and 2005, the Company issued 32,504, 29,827, and 13,926 shares, respectively, of 

common stock from treasury to its non-employee directors pursuant to the Company’s non-employee director 
stock compensation plan.  The Company recorded compensation expense related to the issuances of shares to non-
employee directors of $983,500, $976,000 and $178,000 for the years ended December 31, 2007, 2006 and 2005, 
respectively. 

On June 30, 2007, the Company converted 427,059 RSUs, which were granted on June 30, 2004, into 

common stock based on the original terms of the RSU award.  The Company and the majority of the grant 
participants mutually agreed to net share settle the awards to cover income and payroll tax withholdings as 
provided for in the plan document and original award agreements.  As a result, the Company issued a net 
302,370 shares of common stock associated with this grant.  The remaining 124,689 shares were withheld to 
satisfy income and payroll tax withholding obligations that occurred upon the delivery of the shares underlying 
those RSUs. 

In measuring compensation expense from the grant of RSUs, SFAS No. 123(R) requires companies to 

estimate the fair value of the award on the grant date.  The fair value of the RSUs is inherently less than the 
market value of an unrestricted security.  The fair value of RSUs has been measured using the Black-Scholes 
option-pricing model.  The Company’s computation of expected volatility was based on the historic volatility of 
St. Mary’s common stock.  The Company’s computation of expected life was determined based on historical 
experience of similar awards, giving consideration to the contractual terms of the awards, vesting schedules, and 
expectations of future employee behavior.  The interest rate for periods within the contractual life of the award 
was based on the U.S. Treasury constant maturity yield at the time of grant.  The fair values of granted RSUs 
were estimated using the following weighted-average assumptions: 

Risk free interest rate 
Dividend yield 
Volatility factor of the expected market 

price of the Company's common stock 

Expected life of the awards (in years)

Upon the adoption of SFAS No. 123(R), the deferred compensation balance of $5.6 million related to 

outstanding RSU awards was reclassified to additional paid-in-capital within the shareholders’ equity section of 
the balance sheet.  This deferred compensation balance had been recorded in accordance with APB Opinion 
No. 25.  The Company had recorded compensation expense in periods prior to January 1, 2006, for restricted 
stock awards based on the intrinsic value on the date of grant.  The intrinsic value was recorded as deferred 
compensation in a separate component of shareholders’ equity and was amortized to compensation expense over 
the vesting period.  SFAS No. 123(R) requires expense recognized subsequent to the adoption date to be based on 
fair value. 

Stock Awards Under the Equity Incentive Compensation Plan 

As part of hiring a new senior executive in the second quarter of 2006, St. Mary granted a special 

common stock award of 20,000 shares that vested immediately upon commencement of employment.  
Approximately $728,000 of compensation expense was recorded related to this award in 2006.  In addition to this 
award, the employee may earn an additional 5,000 shares over a four-year period and an additional 15,000 shares 
contingent on the Company meeting certain net asset growth performance conditions over a four-year period.  The 
fair value of this award will be recorded as compensation expense over the vesting period.  For the years ended 
December 31, 2007 and 2006 the Company recorded compensation expense of $136,000 and $27,000 
respectively, related to the contingent award.

Stock Option Grants Under the Equity Incentive Compensation Plan 

The Company has previously granted stock options under the St. Mary Land & Exploration Company 

Stock Option Plan and St. Mary Land & Exploration Company Incentive Stock Option Plan.  The last issuance of 
stock options was December 31, 2004.  Stock options to purchase shares of the Company’s common stock had 
been issued to eligible employees and members of the Board of Directors.  All options granted to date under the 
option plans have been granted at exercise prices equal to the respective closing market price of the Company’s 
underlying common stock on the grant dates, which generally occurred on the last date of a fiscal period.  All 
stock options granted under the option plans are exercisable for a period of up to ten years from the date of grant.   

During the year ended December 31, 2007, the Company recognized stock-based compensation expense 

of approximately $437,000 related to stock options that were outstanding and unvested as of January 1, 2006.  
There was no cumulative effect adjustment from the adoption of SFAS No. 123(R). 

Prior to adopting SFAS No. 123(R), all tax benefits resulting from the exercise of stock options were 

presented as operating cash flows in the accompanying consolidated statements of cash flows.  SFAS No. 123(R) 
requires cash flows resulting from excess tax benefits to be classified as a part of cash flows from financing 
activities.  Excess tax benefits are realized tax benefits from tax deductions for exercised options in excess of the 
deferred tax asset attributable to stock compensation costs for such options.  The Company has recorded 
$9.9 million and $16.1 million of excess tax benefits for the years ended December 31, 2007, and 2006, 
respectively, as cash inflows from financing activities.  Cash received from option exercises under all share-based 
payment arrangements for the years ended December 31, 2007, 2006, and 2005, was $9.1 million, $16.9 million, 
and $10.6 million, respectively.

Note 8 – Pension Benefits 

The Company has a non-contributory pension plan covering substantially all employees who meet age 

and service requirements (the “Qualified Pension Plan”).  The Company also has a supplemental non-contributory 
pension plan covering certain management employees (the “Nonqualified Pension Plan”). 

On December 31, 2006, the Company adopted the recognition and disclosure provisions of Statements of 

Financial Accounting Standards No. 158, “Employers’ Accounting for Defined Benefit Pension and Other 
Postretirement Plans – an Amendment of FASB Statements No. 87, 88, 106, and 132(R)” (“SFAS No. 158”).  
This standard requires the Company to recognize the funded status (i.e., the difference between the fair value of 
plan assets and the projected benefit obligation) of its pension plan in the consolidated balance sheets as either an 
asset or a liability, with a corresponding adjustment to accumulated other comprehensive income, net of tax.  The 
adjustment to accumulated other comprehensive income at adoption represented the net unrecognized actuarial 
losses and unrecognized prior service costs, both of which were previously netted against the plan’s funded status 
in the Company’s consolidated balance sheets pursuant to the provisions of Statements of Financial Accounting 
Standards No. 87, “Employers’ Accounting for Pensions” (“SFAS No. 87”).  These amounts will be subsequently 
recognized as net periodic pension cost pursuant to the Company’s accounting policy for amortizing such 
amounts.  Further actuarial gains and losses that arise in subsequent periods and are not recognized as net periodic 
pension cost in the same periods will be recognized as a component of other comprehensive income.  Those 
amounts will be subsequently recognized as a component of net periodic pension cost on the same basis as the 
amounts recognized in accumulated other comprehensive income at adoption of SFAS No. 158.

The incremental effects of adopting the provisions of SFAS No. 158 on the Company’s statement of 

financial position at December 31, 2006, are presented in the following table.  The adoption of SFAS No. 158 had 
no effect on the Company’s accompanying consolidated statements of operations for the year ended 
December 31, 2006, or for any prior period presented, and it will not affect the Company’s operating results in 
future periods.  The effect of recognizing this additional liability is included in the table below in the column 
labeled “Prior to Adopting SFAS No. 158.”

recognized in the accompanying statement of financial position as long-term accrued pension liability.  No plan 
assets of the Qualified Pension Plan are expected to be returned to the Company during the fiscal year ended 
December 31, 2008.  There are no plan assets in the Nonqualified Pension Plan.

Equity securities do not include any shares of the Company’s common stock for any period presented.  
There is no asset allocation for the Nonqualified Pension Plan since that plan does not have its own assets.  An 
expected return on plan assets of 7.5 percent was used to calculate the Company’s obligation under the Qualified 
Pension Plan.  Factors considered in determining the expected return include the 60 percent equity and 40 percent 
debt securities mix of investment for plan assets and the long-term historical rate of return provided by the equity 
and debt securities markets.  The estimated rate of return on plan assets was 7.5 percent for 2007 and 2006.  The

Note 9 – Asset Retirement Obligations 

The Company recognizes an estimated liability for future costs associated with the abandonment of its oil 
and gas properties.  A liability for the fair value of an asset retirement obligation and a corresponding increase to 
the carrying value of the related long-lived asset are recorded at the time a well is completed or acquired.  The 
increase in carrying value is included in proved oil and gas properties in the accompanying consolidated balance 
sheets.  The Company depletes the amount added to proved oil and gas property costs and recognizes expense in 
connection with the accretion of the discounted liability over the remaining estimated economic lives of the 
respective oil and gas properties.  Cash paid to settle asset retirement obligations is included in the operating 
section of the Company’s accompanying consolidated statements of cash flows. 

The Company’s estimated asset retirement obligation liability is based on historical experience in 

abandoning wells, estimated economic lives, estimates as to the cost to abandon the wells in the future, and 
federal and state regulatory requirements.  The liability is discounted using a credit-adjusted risk-free rate 
estimated at the time the liability is incurred or revised.  The credit-adjusted risk-free rates used to discount the 
Company’s abandonment liabilities range from 6.50 percent to 7.25 percent.  Revisions to the liability could occur 
due to changes in estimated abandonment costs or well economic lives, or if federal or state regulators enact new 
requirements regarding the abandonment of wells.

Accounts payable and accrued expenses as of December 31, 2007, contain $3.1 million related to the 
Company’s asset retirement obligation.  The amount relates to the estimated plugging and abandonment costs 
associated with one offshore platform that was destroyed during Hurricane Rita.  Plugging and abandonment of 
the platform is expected to be completed during the second quarter of 2008.  Please refer to Note 12 – Insurance 
Settlement for additional details.  Accounts payable and accrued expenses did not contain any amount related to 
the Company’s asset retirement obligation as of December 31, 2006. 

Note 10 – Derivative Financial Instruments 

Oil and Gas Commodity Hedges 

To mitigate a portion of the potential exposure to adverse market changes, the Company has entered into 
various derivative contracts.  The Company’s derivative contracts in place include swap and collar arrangements 
for the sale of oil, natural gas, and natural gas liquids.  Please refer to the tables under Summary of Oil and Gas 
Production Hedges in Place in Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and 
Results of Operations, for details regarding the Company’s hedged volumes and associated prices.  As of 
December 31, 2007, the Company has hedge contracts in place through 2011 for a total of approximately 
11.4 million Bbls of anticipated crude oil production, 70.2 million MMBtu of anticipated natural gas production, 
and 1.4 million Bbls of anticipated natural gas liquids production. 

The Company attempts to qualify its oil and natural gas derivative instruments as cash flow hedges for 
accounting purposes under SFAS No. 133 and related pronouncements.  The Company formally documents all 
relationships between the derivative instruments and the hedged production, as well as the Company’s risk 
management objective and strategy for the particular derivative contracts.  This process includes linking all 
derivatives that are designated as cash flow hedges to the specific forecasted sale of oil or gas at its physical 
location.  The Company also formally assesses (both at the derivative’s inception and on an ongoing basis) 
whether the derivatives being utilized have been highly effective at offsetting changes in the cash flows of hedged 
production and whether those derivatives may be expected to remain highly effective in future periods.  If it is 
determined that a derivative has ceased to be highly effective as a hedge, the Company will discontinue hedge 
accounting prospectively.  If hedge accounting is discontinued and the derivative remains outstanding, the 
Company will recognize all subsequent changes in its fair value on the Company’s consolidated statements of 
operations for the period in which the change occurs.  As of December 31, 2007, all oil and natural gas derivative 
instruments qualified as cash flow hedges for accounting purposes.  The Company anticipates that all forecasted 
transactions will occur by the end of their originally specified periods.  All contracts are entered into for other than 
trading purposes. 

The Company’s oil and gas hedges are measured at fair value and are included in the accompanying 

consolidated balance sheets as assets or liabilities.  The Company evaluates market prices in active markets to 
establish the valuation of derivative instruments.  The Company compares valuation estimates against mark-to-
market statements from counterparties for reasonableness.  Management believes that this approach provides a 
reasonable, non-biased, verifiable, and consistent methodology for valuing derivative instruments.  The derivative 
instruments utilized by the Company are not considered by management to be complex, structured, or illiquid.

The oil and gas derivative markets are highly active.  The fair value of oil and natural gas derivative contracts 
designated and qualifying as cash flow hedges under SFAS No. 133 was a net liability of $264.1 million at 
December 31, 2007.   

The Company realized a net gain of $19.3 million, a net gain of $20.5 million, and a net loss of 
$24.4 million from its oil and gas derivative contracts for the years ended December 31, 2007, 2006, and 2005, 
respectively. 

After-tax changes in the fair value of derivative instruments designated as cash flow hedges, to the extent 

they are effective in offsetting cash flows attributable to the hedged risk, are recorded in other comprehensive 
income until the hedged item is recognized in earnings upon the sale of the hedged production.  As of 
December 31, 2007, the amount of unrealized loss net of deferred income taxes to be reclassified from accumulated 
other comprehensive income to oil and gas production operating revenues in the next twelve months was 
$48.0 million.   

Any change in fair value resulting from ineffectiveness is recognized currently in unrealized derivative 
loss in the accompanying consolidated statements of operations.  Unrealized derivative loss for the years ended 
December 31, 2007, 2006, and 2005, includes net losses of $4.1 million, $8.1 million, and $1.8 million, respectively, 
from ineffectiveness related to oil and natural gas derivative contracts.   

Gains or losses from the settlement of oil and gas derivative contracts are reported in the total operating 

revenues section of the accompanying consolidated statements of operations.   

The Company seeks to minimize ineffectiveness by entering into oil derivative contracts indexed to 

NYMEX and natural gas derivative contracts indexed to regional index prices associated with pipelines in 
proximity to the Company’s areas of production.  As the Company’s derivative contracts contain the same index 
as the Company’s sale contracts, this results in hedges that are highly correlated with the underlying hedged item.

Interest Rate Derivative Contracts 

In September 2007 the Company entered into a one year floating-to-fixed interest rate derivative contract for 

a notional amount of $75 million.  Under the agreement, the Company will pay a fixed rate of 4.90 percent and will 
be paid a variable rate based on the one-month LIBOR rate.  The interest rate derivative contract is measured at fair 
value using quoted prices in active markets.  The liability in the accompanying consolidated balance sheet at 
December 31, 2007, was $447,000.  The interest rate swap is a straightforward, non-complex, non-structured 
instrument that is highly liquid  This derivative qualifies for cash flow hedge treatment under SFAS No. 133 and 
related pronouncements.  The Company recorded a net derivative gain of $57,000 in the accompanying

contract. 

Convertible Note Derivative Instrument 

In relation to the Company’s 5.75% Senior Convertible Notes converted in March 2007, the Company 

entered into fixed-to-floating interest rate swaps on $50 million of principal in October 2003.  Due to the 
continued increases in interest rates, the Company entered into a floating-to-fixed interest rate swap in April 2005 
through March 20, 2007, for this same notional amount of $50 million in order to effectively offset our fixed-to-
floating interest rate swaps.  The impact of this instrument, when combined with the other interest rate swaps, was 
that the Company fixed the net liability related to the interest rate swaps, and paid a 1.1 percent interest factor on 
$50 million of notional debt through March 2007.  The contingent interest provision of the 3.50% Senior 
Convertible Notes is a derivative instrument.  However, the value of the derivative was determined to be de 
minimis at the inception of the instrument. 

Note 11 – Repurchase of Common Stock   

Stock Repurchase Program 

In July 2006 the Company’s Board of Directors approved an increase of 5,473,182 shares to the 

remaining authorized number of shares that can be repurchased under the Company’s original authorization 
approved in August 1998, for a total number of shares to be repurchased under the plan of 6 million.  As of the 
date of this filing, the Company has Board authorization to repurchase up to 5,207,784 shares of common stock.  
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 St. Mary’s existing credit facility 
agreement and compliance with securities laws.  Stock repurchases may be funded with existing cash balances, 
internal cash flow, and borrowings under the credit facility.  During 2007 the Company repurchased 792,216 shares 
of its outstanding common stock in the open market at a weighted-average price of $32.76 per share, including 
commissions, for a total of $26.0 million.  During 2006 the Company repurchased 3,319,300 shares of its 
outstanding common stock in the open market at a weighted-average price of $37.09 per share, including 
commissions, for a total of $123.1 million.  During 2005 the Company repurchased 1,175,282 shares of its 
outstanding common stock in the open market at a weighted-average price of $24.59 per share, including 
commissions, for a total of $28.9 million.  The Company did not retire any shares in 2007.  The Company retired 
3,275,689 shares in 2006 and 1,411,356 shares in 2005.  

Note 12 – Insurance Settlement 

In April of 2007 the Company reached a global insurance settlement for reimbursement of damages 

sustained during Hurricane Rita.  St. Mary’s net amount of the final settlement was approximately $33 million.  
As a result of this settlement, the Company recorded a gain of $5.2 million in other revenue in the accompanying 
statement of operations for the year ended December 31, 2007.  The Company experienced significant weather-
related delays in its plug and abandonment efforts during 2007 and consequently accrued an additional 
$2.1 million of plug and abandonment costs for one offshore platform during the fourth quarter of 2007.  The gain 
calculation takes into consideration a total of approximately $12.1 million of costs associated with the plugging 
and abandonment of the above-mentioned offshore platform.  Any significant variation between actual and 
estimated plugging and abandonment and outside-operated damage repair costs will impact the final 
determination of the gain associated with the insurance settlement.  The Company expects adjustments to the gain 
to be completed by the second quarter of 2008.

The exploratory well costs capitalized for more than one year includes $4.8 million for a well that was 

drilled in 2005 and 2006 and is located offshore in the Gulf of Mexico.  A Reserve Analysis and Reservoir 
Simulation Study has been completed for this well.  Construction of a long lead-time infrastructure began in 2007 
and is expected to be completed during the fourth quarter of 2008.  Production from this well is expected to 
commence in 2009.  The operational plan is to build the connection and process facilities in support of the already 
recognized costs.  The Company believes these costs are realizable. 

The exploratory well costs capitalized for more than one year also includes $5.7 million and $3.1 million 
of costs related to two additional wells located offshore in the Gulf of Mexico that were drilled in 2006.  Reserve 
Analysis and Reservoir Simulation Studies have been completed for these wells to support the ongoing project 
economics.  The wells were both waiting on the construction of production facilities, which were completed in 
late 2007.  Production from both of these wells is expected to commence during the first quarter of 2008.  Based 
on the operational plan and project economics for these wells, the Company believes these costs are realizable. 

Oil and Gas Reserve Quantities (Unaudited) 

For all years presented, Netherland, Sewell and Associates, Inc. (“NSAI”) prepared the reserve information 
for the Company’s coalbed methane projects at Hanging Woman Basin in the northern Powder River Basin as well 
as the Company’s non-operated coalbed methane interests in the Green River Basin.  The Company engaged Ryder 
Scott Company, L.P. to review internal engineering estimates for 80 percent of the PV-10 value of its proven 
conventional oil and gas reserves in 2007 and 2006.  In 2005, Ryder Scott Company, L.P. prepared the reserve 
estimates for at least 80 percent of the PV-10 value of the Company's conventional oil and gas assets.  St. Mary 
personnel prepared the reserve estimates for the remainder of all properties.  The Company emphasizes that reserve 
estimates are inherently imprecise and that estimates of new discoveries and undeveloped locations are more 
imprecise than estimates of established producing oil and gas properties.  Accordingly, these estimates are expected 
to change as future information becomes available.   

Proved oil and gas reserves are the estimated quantities of crude oil, natural gas, and natural gas liquids that 
geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known 
reservoirs under existing economic and operating conditions.  Proved developed oil and gas reserves are those 
expected to be recovered through existing wells with existing equipment and operating methods.  All of the 
Company’s proved reserves are located in the continental United States and offshore in the Gulf of Mexico.

Standardized Measure of Discounted Future Net Cash Flows (Unaudited) 

Statement of Financial Accounting Standards No. 69, “Disclosures about Oil and Gas Producing Activities” 

(“SFAS No. 69”) prescribes guidelines for computing a standardized measure of future net cash flows and changes 
therein relating to estimated proved reserves.  The Company follows these guidelines, which are briefly discussed 
below. 

Future cash inflows and future production and development costs are determined by applying benchmark 

prices and costs, including transportation, quality, and basis differentials, in effect at year end to the year-end 
estimated quantities of oil and gas to be produced in the future.  Each property the Company operates is also charged 
with field-level overhead in the estimated reserve calculation.  Estimated future income taxes are computed using 
current statutory income tax rates, including consideration for estimated future statutory depletion.  The resulting 
future net cash flows are reduced to present value amounts by applying a ten percent annual discount factor. 

Future operating costs are determined based on estimates of expenditures to be incurred in developing and 

producing the proved oil and gas reserves in place at the end of the period using year-end costs and assuming 
continuation of existing economic conditions, plus Company overhead incurred by the central administrative office 
attributable to operating activities.

The assumptions used to compute the standardized measure are those prescribed by the FASB and the 

Securities and Exchange Commission.  These assumptions do not necessarily reflect the Company's expectations of 
actual revenues to be derived from those reserves, nor their present value.  The limitations inherent in the reserve 
quantity estimation process, as discussed previously, are equally applicable to the standardized measure 
computations since these reserve quantity estimates are the basis for the valuation process.  The following prices as 
adjusted for transportation, quality, and basis differentials, were used in the calculation of the standardized measure:

(1) General and administrative and exploration expense are components of total operating expenses.  As a result of a 
change in circumstances in 2007, the Company began classifying all payments made under the Net Profits Plan to 
exploration overhead only for those individuals who are currently employed by St. Mary and who continue to be 
involved in the Company’s exploration efforts.  Therefore, the quarterly financial information presented in the following 
table reflects a reconciliation from what was previously reported in the quarterly reports on Form 10-Q, to the 
reclassified balances, which reflect current distributions being made and accrued for under the Net Profits Plan for 
former employees as being fully allocated to general and administrative expense since there is no longer any functional 
link to geologic and geophysical or exploration related work by those former employees.  The reclassification was 
determined in the fourth quarter, therefore, no reclassification was necessary as the amounts reported for the fourth 
quarter were accounted for consistent with the current presentation.  The change had no impact on total operating 
expenses, income from operations, income before income taxes, net income, basic net income per share, or diluted net 
income per share as it was simply a reclassification between two line items within the accompanying consolidated 
statements of operations as shown below.
