Description and Location of Our Drilling Rigs.    A land drilling rig is
composed of major equipment components, such as engines, drawworks or hoists, derrick or mast, substructure, pumps to circulate the drilling fluid, blowout preventers and drill pipe that are collectively unitized into an operating system commonly
referred to as a drilling rig. As a result of the normal wear and tear of operating 24 hours a day, several of the major components of a drilling rig, such as engines, mud pumps and drill pipe, must be replaced or rebuilt on a periodic basis. Other
components, such as the substructure, mast and drawworks, can be used for extended periods of time with proper maintenance. We also own additional equipment used in the operation of our drilling rigs, including top drives, skidding systems, large
air compressors, trucks and other support equipment.

The maximum depth capacities of our various drilling rigs range from
5,000 to 40,000 feet. In 2009, 82 of our 130 available drilling rigs were used in drilling services.

The following table
shows certain information about our drilling rigs (including their distribution) as of February 12, 2010:

##### Table of Contents

With the dramatic downturn in drilling activity that started in the fourth quarter of 2008,
we consolidated our nine operating divisions into six at the beginning of 2009 in an effort to minimize cost and streamline operating efficiencies. Currently our operating divisions consist of the following: Panhandle, Arkoma, Gulf Coast,
Mid-continent, Woodward, and Rocky Mountain.

Anadarko Basin.The Anadarko Basin is a geologic
feature covering approximately 50,000 square miles primarily in Central and Western Oklahoma, but also includes the upper Texas Panhandle, southwestern Kansas and southeastern Colorado region. The basin contains sedimentary deposits ranging in
thickness from 2,000 feet on its northern and western flanks to 40,000 feet in its southern portion.

During 2009, our
Mid-Continent and Woodward divisions marketed 45 drilling rigs in the Anadarko Basin including part of the Texas Panhandle. These two divisions averaged 10 and four drilling rigs operating during 2009, respectively.

Panhandle of Texas.During 2009, we marketed 23 drilling rigs through our Panhandle division. Only four
drilling rigs operated during the year in this division. We remain the largest drilling contractor in the combined Anadarko Basin of Oklahoma and the Texas Panhandle in terms of total rig count.

Arkoma Basin.The Arkoma Basin is another geologic feature that encompasses approximately 33,800 square miles
of southeastern Oklahoma and west-central Arkansas. The Arkoma Basin holds deposits ranging in thickness from 3,000 to 20,000 feet. It contains multiple conventional gas plays as well as two of the more recent notable unconventional playsthe
Woodford Shale and Fayetteville Shale.

During 2009, Our Arkoma division marketed 11 drilling rigs with an average of two
drilling rigs operating.

East Texas, Louisiana, Gulf Coast and the North Texas Barnett
Shale.Our Gulf Coast division provides drilling rigs to the onshore areas of the south Louisiana Gulf Coast and upper Texas Gulf Coast region as well as the conventional and unconventional gas plays of northwest Louisiana
and East Texas. During 2009 our North Texas division was consolidated into the Gulf Coast division. The Gulf Coast division marketed 25 drilling rigs during 2009, with an average of nine drilling rigs operating for the year. The increased interest
in the Haynesville Shale play provided an opportunity for us to reposition one drilling rig during the year into this active market area and we added a new 1,500 horsepower rig at the end of 2009.

North Central Texas is the home of the Barnett Shale, a tight gas bearing formation. It is touted as one of the largest natural gas fields
in the U.S., and as being one of the first unconventional shale gas formations to have been unlocked by technological advances in the use of multi-stage high pressure fracturization completion processes.

Due to the downturn in rig activity in the Barnett Shale during 2009, we did not operate any rigs in this market. Three rigs recently
secured contracts to begin operations in the Barnett Shale in the first quarter of 2010.

Rocky
Mountains.The Rocky Mountain area covers several states, including Colorado, Utah, Wyoming, Montana and North Dakota. This vast area has produced a number of conventional and unconventional oil and gas fields. Our
drilling rig fleet in this division has 26 drilling rigs of which it operated an average of 10 drilling rigs during 2009. We have drilling rigs operating in the Pinedale Anticline of western Wyoming and the Uintah Basin in eastern Utah, as well as
other areas throughout this expansive geographical area. An additional drilling rig was moved into the Bakken Shale in North Dakota during the year, and a new 1,500 horsepower rig is being mobilized into this play during the first quarter of 2010.

At any given time our ability to use all of our drilling rigs is dependent on a number of conditions besides demand,
including the availability of qualified labor and the availability of needed drilling supplies and

equipment. Not surprisingly, the impact of these various conditions tends to fluctuate with the demand for our drilling rigs. In 2007, our average utilization rate was 80%. In late 2008, our
utilization rate was significantly affected by the U.S. and world economic downturn. For the first nine months of 2008 our average utilization rate was 81%, by December 2008, our average utilization rate had declined to 61%. For 2009, our average
utilization rate declined to 30%. This decline in drilling rig utilization reduced the competition for labor during 2009 which in turn reduced the upward pressure on our labor costs.

The following table shows the average number of our drilling rigs working by quarter for the years indicated:

Acquisitions and Construction.    During the second quarter of 2008, we
completed the construction of two new 1,500 horsepower diesel electric drilling rigs for approximately $32.2 million and placed these drilling rigs into service in our Rocky Mountain division. During the fourth quarter of 2008, we completed the
construction of another new 1,500 horsepower diesel electric drilling rig for approximately $14.1 million and placed this drilling rig into service in North Dakota.

We negotiated with our equipment suppliers postponement or cancellation of orders where possible; however, during 2008 we paid approximately $31.7 million for the purchase of major components that we
intended to use in the construction of the eight new drilling rigs. We plan to maintain this equipment for future use.

During
the first quarter 2009, we sold one 750 horsepower mechanical drilling rig for $3.1 million and recorded a $0.9 million gain. During the third quarter 2009, we sold a 1,000 horsepower mechanical drilling rig for $2.8 million and recorded a $1.9
million gain. During the fourth quarter 2009, we sold a 1,000 horsepower mechanical drilling rig for $2.7 million and recorded a $2.0 million gain and acquired one new 1,500 horsepower diesel electric drilling rig for $13.2 million.

We agreed to delay the delivery of a new 1,500 horsepower diesel electric drilling rig that was to have been delivered to North Dakota under
a long term contract in the first quarter of 2009. Under that agreement, our customer agreed to make monthly payments pending the future delivery of the rig. Our customer has now advised us to prepare the rig for mobilization to North Dakota
for use in their drilling program during the first quarter of 2010.

In January and February 2010, our contract drilling
segment entered into contracts to sell eight of its idle mechanical drilling rigs to an unaffiliated third party. These drilling rigs ranged in horse power from 800 to

1,000. The closing on three of these drilling rigs occurred in February. Three more are scheduled to close during the first quarter of 2010 with the last transaction for the remaining two
rigs anticipated to close during the second quarter of 2010. Proceeds from the sale of all the drilling rigs will be $23.9 million resulting in an estimated gain of $6.1 million. The proceeds from this sale will be used to refurbish and upgrade
additional rigs in our fleet in order that those rigs can be used in horizontal drilling operations. We also placed into service in our Rocky Mountain division a 1,500 horsepower, diesel-electric drilling rig that previously had been placed on hold
during 2009 by our customer. At completion of the sale of the eight rigs and with the additional rig recently placed into service, this segment will have 123 drilling rigs in its fleet.

Over half of our drilling rig fleet is currently equipped to drill horizontal wells common in the unconventional oil and gas plays, while
the balance of the fleet is equipped to drill the more conventional vertical and directional type wells. These drilling rigs can be modified to drill the horizontal type wells, which is why we have allocated a portion of our 2010 capital budget
to refurbish eight drilling rigs for this purpose.

Drilling Contracts.    Our drilling
contracts are generally obtained through competitive bidding on a well by well basis. Contract terms and payment rates vary depending on the type of contract used, the duration of the work, the equipment and services supplied and other matters. We
pay certain operating expenses, including the wages of our drilling personnel, maintenance expenses and incidental drilling rig supplies and equipment. The contracts are usually subject to termination by the customer on short notice and on payment
of a fee. Our contracts also contain provisions regarding indemnification against certain types of claims involving injury to persons, property and for acts of pollution. The specific terms of these indemnifications are subject to negotiation on a
contract by contract basis.

The type of contract used determines our compensation. Contracts are generally one of three
types: daywork; footage; or turnkey. Additional compensation may be acquired for special risks and unusual conditions. Under a daywork contract, we provide the drilling rig with the required personnel and the operator supervises the drilling of the
well. Our compensation is based on a negotiated rate to be paid for each day the drilling rig is used. Footage contracts usually require us to bear some of the drilling costs in addition to providing the drilling rig. We are paid on completion of
the well at a negotiated rate for each foot drilled. Under turnkey contracts we drill the well to a specified depth for a set amount and provide most of the required equipment and services. We bear the risk of drilling the well to the contract depth
and are paid when the contract provisions are completed.

Under turnkey contracts we may incur losses if we underestimate the
costs to drill the well or if unforeseen events occur that increase our costs or result in the loss of the well. To date, we have not experienced significant losses in performing turnkey contracts. In 2009, 2008 and 2007, we did not drill any
turnkey wells. The majority of our work in 2009 was under daywork contracts. Because market demand for our drilling rigs as well as the desires of our customers determine the types of contracts we use, we cannot predict when and if a part of our
drilling will be conducted under footage or turnkey contracts.

The majority of our contracts are on a well-to-well basis,
with a small portion under term contracts. Term contracts range from six months to two years in length of term and depending on the contract, the rates can either be fixed throughout the term or allow for adjustment at periodic intervals.

Customers.    During 2009, Questar Corporation was our largest drilling customer accounting
for approximately 35% of our total contract drilling revenues. No other third party customer accounted for 10% or more of our contract drilling revenues. During 2009, 2008 and 2007, we drilled 38, 122 and 77 wells, respectively, for our oil and
natural gas segment. As required by the SEC, the profit received by our contract drilling segment when it drills wells for our oil and natural gas segment is used to reduce the carrying value of our oil and natural gas properties rather than being
included in our operating profit. As a result, for 2009, 2008 and 2007 we reduced the carrying value of our oil and gas properties by $1.3 million, $27.9 million and $22.7 million, respectively.

OIL AND NATURAL GAS

General.    In 1979, we began to develop our exploration and production operations as a means of
diversifying our operations. Today, our wholly owned subsidiary, Unit Petroleum Company, conducts our exploration and production activities. Our producing oil and natural gas properties, undeveloped leaseholds and related assets are located mainly
in Oklahoma, Texas, Louisiana and New Mexico and, to a lesser extent, in Arkansas, North Dakota, Colorado, Wyoming, Montana, Alabama, Kansas, Mississippi, Michigan, Pennsylvania, Maryland and a small portion in Canada.

When we are the operator of a property, we generally attempt to use a drilling rig owned by our contract drilling segment.

The following table presents certain information regarding our oil and natural gas operations as of December 31, 2009:

Description and Location of Our Core Operations

West division.Segno Wilcox is located primarily in Polk, Tyler and Hardin counties,
Texas, our Segno prospect continues to grow as we have expanded our prospect area to the south by entering into a joint exploration agreement with an unaffilated third-party for the use of a proprietary 3-D seismic survey covering approximately 151
square miles. We plan to drill three Wilcox wells during the first half of 2010 and pay certain leasehold extensions in order to earn working interest in the wells, the acreage block (approximately 29,000 gross acres) and a license to the 3-D
seismic data. For 2009, we completed eight wells at an average working interest of 86% and a 75% success rate. The average completed gross well cost was approximately $2.7 million per well with average estimated gross reserves of 3.0 Bcfe per well.
For 2010, we plan on drilling 23 gross (17.5 net) wells in this division with an approximate total net cost of $48.0 million dollars.

East division.In the Haynesville shale, we have two areas of activity located in Shelby and Harrison counties, East Texas. In 2009, we have drilled 15 gross vertical wells and one gross horizontal well at a
total approximate net cost of $38.7 million. We own an average of 65% working interest in the vertical wells which have an average gross well cost of $3.1 million per well. The estimated reserves on a per well basis is 0.7 Bcfe from several
different formations including the Cotton Valley Lime, Haynesville Shale, Travis Peak and Pettit formations. The decision to drill vertical wells was primarily based on leasehold obligations that were required to maintain leases. In Harrison County,
we drilled and operated our first horizontal Haynesville well during the latter part of 2009 at an approximate cost of $6.7 million. The well penetrated approximately 3,000 of Haynesville Shale and is scheduled to be fracture stimulated in
seven stages with approximately 300,000 pounds

of sand per stage. The first three stages have recently been successfully pumped and the remaining four stages will be pumped near the end of the first quarter of 2010. For 2010, we anticipate
participating in five horizontal Haynesville wells and two vertical wells at an approximate total net cost of $31.0 million. We own approximately 16,200 gross and 11,300 net acres in Shelby County and 20,000 gross and 8,700 net acres in Harrison
County.

In the Marcellus Shale, of our 197,000 gross and 49,500 net acres, 94% is located in Somerset County, PA. During
2009, we participated with a 25% working interest in three vertical wells and two horizontal wells at a total net cost of $7.3 million. The vertical wells were drilled in three distinct prospect areas to gather core and log data across a large
portion of the leasehold and aid in the selection of the drilling location for the two horizontal wells. Both horizontal wells have been drilled to total depth and achieved lateral lengths of approximately 3,500. The first horizontal well has
recently been fracture stimulated in seven stages with 500,000 pounds of sand per stage. We are in the early phase of analyzing the frac and test data and are conducting an extended flow test into the gas sales line. The second horizontal well is
scheduled to be fracture stimulated in the second quarter of 2010.

Central
division.We concentrate our Granite Wash (GW) drilling program primarily in the Texas Panhandle portion of the play. In 2009, we drilled and operated 13 vertical wells and one horizontal well. The vertical
wells had an average working interest of 66% and estimated gross reserves of 1.8 Bcfe per well at an average gross completed well cost of $2.3 million per well. We have a 70% working interest in the horizontal GW well with estimated gross reserves
of 6.0 to 8.0 Bcfe at an approximate gross completed well cost of $3.8 million. The well has a 4,000 lateral that was fracture stimulated in 11 stages utilizing 48,000 bbls of water and 1,000,000 pounds of sand. Peak production averaged 4.2
MMcf per day of natural gas, 600 bbls of liquids per day, and 500 bbls of oil per day over a 30 day period beginning in late December 2009. For 2010, we plan on participating in approximately nine gross vertical wells and 31 gross horizontal wells
at a total net cost of approximately $70.0 million. The estimated average working interest for the 2010 wells is approximately 45% and we anticipate operating 21 of those wells. We own approximately 95,000 gross and 38,000 net acres in the GW
play.

Acquisitions.    On January 18, 2008, we purchased a 50% interest
in a 6,800 gross-acre leasehold that we did not already own in our Segno area of operations located in Hardin County, Texas. Included in this purchase were five producing wells with 4.9 Bcfe of then estimated proved reserves and production of 2.8
MMcf of natural gas per day and 88.2 barrels of condensate. The purchase price was $16.8 million of which $15.8 million was allocated to the reserves of the wells and $1.0 million was allocated to the undeveloped leasehold.

In September 2008, we completed an acquisition consisting of a 75% working interest in four producing wells and other proved undeveloped
properties for $22.2 million along with working interests in undeveloped leasehold valued at approximately $3.5 million, all located in the Texas Panhandle region.

During 2008 and 2009, we acquired interests in approximately 60,000 net undeveloped acres in the Marcellus Shale Play, located mainly in Pennsylvania and Maryland for approximately $43.6 million. In July
2009, we received $7.1 million and approximately 1,500 net undeveloped acres, representing payment for our 50% interest in 4,000 gross undeveloped acres and reimbursement for costs we paid on their behalf. On September 30, 2009, per our
agreement with certain unaffiliated third parties, we were paid approximately $14.9 million for our 50% interest in approximately 18,000 gross undeveloped acres of the Marcellus Shale and $26.1 million for a receivable from the third parties for
their 50% share of the costs we paid on their behalf to acquire the acreage. The sales proceeds reduced undeveloped leasehold and no gain or loss was recorded on this sale. We now have an interest in approximately 50,500 net undeveloped acres.

The recent SEC
rules for reserve disclosures went into effect for the fiscal year ended December 31, 2009. Oil, NGLs and natural gas reserves cannot be measured exactly. Estimates of oil, NGLs and natural gas reserves require extensive judgments of reservoir
engineering data and are generally less precise than other estimates made in connection with financial disclosures. We use Ryder Scott Company L.P. (Ryder Scott), independent petroleum consultants, to audit our reserves as prepared by our reservoir
engineers. Ryder Scott has been providing petroleum consulting services throughout the world for over seventy years, their summary report is attached as Exhibit 99.1 to this Form 10-K. The wells or locations for which estimates of reserves were
audited were reserves that comprised the top 85% of the total proved discounted future net income based on the unescalated pricing policy of the SEC as taken from reserve and income projections prepared by us as of December 31, 2009.

Our Reservoir Engineering department is responsible for reserve determination for all wells in which we have an interest.
Their primary objective is to accurately estimate our future reserves and their future net value to

us. Data is incorporated from multiple sources including geological, production engineering, marketing, production, land and accounting departments. The engineers are responsible for reviewing
this information for accuracy as it incorporated into the reservoir engineering database and the internal audit group has a checklist of review tasks to confirm the correctness of data transfer. New well reserve estimates are provided to management
as well as the respective operational divisions for additional scrutiny. Major reserve changes on existing wells are reviewed on a regular basis with the operational divisions to confirm correctness and accuracy. As the external audit is being
completed by Ryder Scott, the reservoir department performs a final review of all properties for accuracy of forecasting.

Technical Qualifications

Ryder ScottMr. Fred P. Richoux is the technical person

Mr. Mitchell have attended various seminars and forums to enhance their understanding of the recent changes that have occurred in SEC rules pertaining to reserves presentation. These forums have included those sponsored by various professional
societies and professional service firms including Ryder Scott.

Definitions and
Other.Proved oil, NGLs and natural gas reserves, as defined in SEC Rule 4-10(a), are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty
to be economically produciblefrom a given date forward, from known reservoirs and under existing economic conditions, operating methods and government regulationsprior to the time at which contracts providing the right to operate expire,
unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably
certain that it will commence the project within a reasonable time.

The area of the reservoir considered as proved includes:



| |  |  | The area identified by drilling and limited by fluid contacts, if any, and
| | - |  | --------------------------------------------------------------------------



| |  |  | Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically
producible oil or gas on the basis of available geosciences and engineering data.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In the absence of data on
fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons (LKH) as seen in a well penetration unless geosciences, engineering or performance data and reliable technology establishes a lower contact with reasonable
certainty.

Where direct observation from well penetrations has defined a highest known oil (HKO) elevation and the potential
exist for an associated gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geosciences, engineering or performance data and reliable technology establish the higher contact with reasonable
certainty.

Reserves which can be produced economically through application of improved recovery techniques (including, but
not limited to, fluid injection) are included in the proved classification when:



| |  |  | Successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole, the operation of
an installed program in the reservoir or other evidence using reliable technology establishes reasonable certainty of the engineering analysis on which the project or program was based; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The project has been approved for development by all necessary parties and entities, including governmental entities.

Existing economic conditions include prices and costs at which economic producibility from a
reservoir is to be determined. The price shall be the average price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first day of month price for each
month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.

Proved undeveloped oil, NGLs and natural gas reserves are proved 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.
Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that establishes reasonable certainty of
economic producibility at greater distances. Undrilled locations can be classified as having undeveloped reserves only if a development plan has been adopted indicating that they are scheduled to be drilled within five years, unless the specific
circumstances, justify a longer time. Under no circumstances shall estimates for proved undeveloped reserves be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such
techniques have been proved effective by actual projects in the same reservoir or an analogous reservoir, or by other evidence using reliable technology establishing reasonable certainty.

As of December 31, 2009, we had approximately 156 gross proved undeveloped wells (PUDs) all of which we have plans to develop within
the next five years for a net cost of approximately $160.0 million. We do not have any material aged PUDs (PUDs greater than five years). Our aged PUDs represent 0.6% of our total proved reserves and 3% of our total PUDs, the majority of which have
already been drilled in 2010. During 2009, we converted 16 PUDs into proved developed wells (PDPs) at a cost of approximately $24.5 million.

Our estimated proved reserves and the standardized measure of discounted future net cash flows of the proved reserves at December 31, 2009, 2008, and 2007, the changes in quantities and standardized
measure of such reserves for the three years then ended, are shown in the Supplemental Oil and Gas Disclosures included in Item 8 of this report.

Contracts.Our oil production is sold at or near our wells under purchase contracts at prevailing prices in accordance with arrangements customary in the oil industry.
Our natural gas production is sold to intrastate and interstate pipelines as well as to independent marketing firms under contracts with terms generally ranging from one month to a year. Few of these contracts contain provisions for readjustment of
price as most of them are market sensitive.

Customers.During 2009, we did
not have a third party customer that accounted for 10% or more of our oil and natural gas revenues, the top five third party customers accounted for approximately 29% of our oil and natural gas revenues. During 2009, our mid-stream segment purchased
$29.3 million of our natural gas production and natural gas liquids and provided gathering and transportation services of $4.6 million. Intercompany revenue from services and purchases of production between our mid-stream segment and our oil and
natural gas segment has been eliminated in our consolidated financial statements. In 2008 and 2007, we eliminated intercompany revenues of $56.3 million and $23.1 million, respectively, of natural gas production and NGLs.

MID-STREAM

General.    Superior is a mid-stream company engaged primarily in the buying, selling, gathering, processing and treating of natural gas and operates three natural gas treatment plants, eight operating
processing plants, 33 active gathering systems and 839 miles of pipeline. Superior and its subsidiary operate in Oklahoma, Texas, Kansas and Pennsylvania.

Acquisitions.Our mid-stream segment did not have any significant acquisitions during 2009 or 2008.

Contracts.Our mid-stream segment provides its customers with a full range of gathering, processing and treating services. These services are usually
provided to each customer under long-term contracts (more than one year), but we do have some short-term contracts as well. Our customer agreements include the following types of contracts:



| |  |  | Fee-Based Contracts.    These contracts provide for a set fee for gathering and transporting raw natural gas. Our
mid-streams revenue is a function of the volume of natural gas that is gathered or transported and is not directly dependent on the value of the natural gas. For the year ended December 31, 2009, 59% of our mid-stream segments total
volumes and 22% of operating margins (as defined below) were under fee-based contracts.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Percent of Proceeds Contracts (POP).    These contracts provide for our mid-stream segment to retain a negotiated percentage
of the sale proceeds from residue natural gas and NGLs it gathers and processes, with the remainder being remitted to the producer. In this arrangement, Superior and the producers are directly dependent on the volume of the commodity and its
value; Superior owns a percentage of that commodity and is directly subject to fluctuations in its market value. For the year ended December 31, 2009, 23% of our mid-stream segments total volumes and 30% of operating margins (as defined
below) were under POP contracts.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Percent of Index Contracts (POI).    Under these contracts our mid-streams segment, as the processor, purchases raw
well-head natural gas from the producer at a stipulated index price and, after processing the natural gas, sells the processed residual gas and the produced NGLs to third parties. Our mid-stream segment is subject to the economic risk
(processing margin risk) that the aggregate proceeds from the sale of the processed natural gas and the NGLs could be less than the amount paid for the unprocessed natural gas. For the year ended December 31, 2009, 18% of our mid-stream
segments total volumes and 48% of operating margins (as defined below) were under POI contracts.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For
the above contracts, operating margin is defined as total operating revenues less operating expenses and does not include depreciation and amortization, general and administrative expenses, interest expense or income taxes.

Customers.During 2009, ONEOK, Tenaska and ConocoPhillips accounted for approximately
52%, 17% and 15%, respectively, of our mid-stream revenues. We believe that if we lost one or more of these three identified customers, that there are other customers available to purchase our gas and liquids.

VOLATILE NATURE OF OUR BUSINESS

The prevailing prices for natural gas, NGLs and oil significantly affect our revenues, operating results, cash flow and future rate of growth. Because natural gas makes up the biggest part of our oil,
NGLs and natural gas reserves, as well as the focus of most of the contract drilling work we do for others, changes in natural gas prices have a larger impact on us than changes in oil and NGL prices. Historically, oil, NGLs and natural gas prices
have been volatile, and we expect them to continue to be so. The following table shows for each of the periods

Prices for oil, NGLs
and natural gas are subject to wide fluctuations in response to relatively minor changes in the supply of and demand for oil and natural gas, market uncertainty and a variety of additional factors that are beyond our control. These factors include:



| |  |  | political conditions in oil producing regions, including the Middle East, Nigeria and Venezuela;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | the ability of the members of the Organization of Petroleum Exporting Countries to agree to and maintain oil price and production controls;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | demand for oil and natural gas from other developing nations including China and India;
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | the price of foreign imports;
| | - |  | -----------------------------



| |  |  | imports of liquefied natural gas;
| | - |  | ---------------------------------



| |  |  | actions of governmental authorities;
| | - |  | ------------------------------------



| |  |  | the domestic and foreign supply of oil and natural gas;
| | - |  | -------------------------------------------------------



| |  |  | the level of consumer demand;
| | - |  | -----------------------------



| |  |  | United States storage levels of natural gas;
| | - |  | --------------------------------------------



| |  |  | the ability to transport natural gas or oil to key markets;
| | - |  | -----------------------------------------------------------



| |  |  | weather conditions;
| | - |  | -------------------



| |  |  | domestic and foreign government regulations;
| | - |  | --------------------------------------------



| |  |  | the price, availability and acceptance of alternative fuels;
| | - |  | ------------------------------------------------------------



| |  |  | the time period associated with the current decrease in commodity prices; and
| | - |  | -----------------------------------------------------------------------------



| |  |  | overall economic conditions in the United States as well as the world.
| | - |  | ----------------------------------------------------------------------

These factors and the volatile nature of the energy markets make it impossible to predict the future prices of oil, NGLs and natural gas.
You are encouraged to read the Risk Factors discussed in Item 1A of this report for additional risks that can impact our operations.

##### Table of Contents

Our contract drilling operations are dependent on the level of demand in our operating
markets. Both short-term and long-term trends in oil and natural gas prices affect demand. Because oil and natural gas prices are volatile, the level of demand for our services can also be volatile. Both demand for our drilling rigs and dayrates
steadily declined throughout 2007. This was followed by a resurgence in activity (as well as rates) during the first nine months of 2008, before a decline in activity during the fourth quarter 2008. Dayrates continued to decline throughout 2009
while our drilling rig utilization hit its low in June 2009 before it started to slowly increase during the later part of the year.

Our mid-stream operations provide us greater flexibility in delivering our (and other parties) natural gas from the wellhead to major natural gas pipelines. Margins received for the delivery of this natural gas is dependent on the price for
oil, natural gas and natural gas liquids and the demand for natural gas in our area of operations. If the price of natural gas liquids falls without a corresponding decrease in the cost of natural gas, it may become uneconomical to us to extract
certain natural gas liquids. The volumes of natural gas processed are highly dependent on the volume and Btu content of the natural gas gathered.

COMPETITION

All of our businesses are highly competitive and price sensitive. Competition in the contract drilling business traditionally involves
factors such as demand, price, efficiency, condition of equipment, availability of labor and equipment, reputation and customer relations. We are the fifth largest U.S. deep onshore drilling contractor.

Our oil and natural gas operations likewise encounter strong competition from other oil and gas companies. Many of these competitors have
greater financial, technical and other resources than we do and have more experience than we do in the exploration for and production of oil and natural gas.

Our mid-stream operations compete with purchasers and gatherers of all types and sizes, including those affiliated with various producers, other major pipeline companies, as well as independent gatherers
for the right to purchase natural gas, build gathering systems in production fields and deliver the natural gas once the gathering systems are established. The principal elements of competition include the rates, terms and availability of services,
reputation and the flexibility and reliability of service.

As discussed elsewhere in this report, throughout 2007 and through
the first nine months of 2008 all of our operations experienced strong competition for qualified labor. However, due to the depressed conditions within our industry during the end of 2008 and throughout 2009, we do not anticipate that competition to
keep and attract qualified drilling employees to meet our immediate future requirements will materially affect us. Likewise, if current commodity price and industry drilling utilization rates continue, we do not anticipate that our contract drilling
labor costs will increase from those levels in effect at the end of the fourth quarter of 2009.

OIL AND NATURAL GAS
PROGRAMS AND CONFLICTS OF INTEREST

Unit Petroleum Company serves as the general partner of 15 oil and gas limited
partnerships. Three of these partnerships were formed for investment by third parties and 12 (the employee partnerships) were formed to allow our employees and directors the opportunity to participate with Unit Petroleum Company in its operations.
The partnerships formed for use in connection with third party investments were formed in 1984 and 1986. One employee partnership has been formed each year beginning with 1984.

The employee partnerships formed in 1984 through 1999 have been consolidated into a single consolidating partnership. The employee
partnerships each have a set annual percentage (ranging from 1% to 15%) of our interest in most of the oil and natural gas wells we drill or acquire for our own account during the year in which the partnership was formed. The total interest the
participants have in our oil and natural gas wells by participating in these partnerships does not exceed one percent of our interest in the wells.

Under the terms of our partnership agreements, the general partner has broad discretionary authority to manage the business and operations of the partnership, including the authority to make decisions
regarding the partnerships participation in a drilling location or a property acquisition, the partnerships expenditure of funds and the distribution of funds to partners. Because the business activities of the limited partners and the
general partner are not the same, conflicts of interest will exist and it is not possible to entirely eliminate these conflicts. Additionally, conflicts of interest may arise when we are the operator of an oil and natural gas well and also provide
contract drilling services. In these cases, the drilling operations are conducted under drilling contracts containing terms and conditions comparable to those contained in our drilling contracts with non-affiliated operators. We believe we fulfill
our responsibility to each contracting party and comply fully with the terms of the agreements which regulate these conflicts.

These partnerships are further described in Notes 2 and 10 to the Consolidated Financial Statements in Item 8 of this report.

EMPLOYEES

As of February 12, 2010, we had approximately 1,094 employees in our contract drilling operations, 154 employees in our oil and natural
gas operations, 75 employees in our mid-stream operations and 93 in our general corporate area. None of our employees are members of a union or labor organization nor have our operations ever been interrupted by a strike or work stoppage. We
consider relations with our employees to be satisfactory.

GOVERNMENTAL REGULATIONS

Our business depends on the demand for services from the oil and natural gas exploration and development industry, and therefore our
business can be affected by political developments and changes in laws and regulations that control or curtail drilling for oil and natural gas for economic, environmental or other policy reasons.

Various state and federal regulations affect the production and sale of oil and natural gas. All states in which we conduct activities
impose restrictions on the drilling, production, transportation and sale of oil and natural gas.

Under the Natural Gas Act of
1938, the Federal Energy Regulatory Commission (the FERC) regulates the interstate transportation and the sale in interstate commerce for resale of natural gas. The FERCs jurisdiction over interstate natural gas sales has been substantially
modified by the Natural Gas Policy Act under which the FERC continued to regulate the maximum selling prices of certain categories of gas sold in first sales in interstate and intrastate commerce. Effective January 1, 1993, however,
the Natural Gas Wellhead Decontrol Act (the Decontrol Act) deregulated natural gas prices for all first sales of natural gas. Because first sales include typical wellhead sales by producers, all natural gas produced from our
natural gas properties is sold at market prices, subject to the terms of any private contracts which may be in effect. The FERCs jurisdiction over natural gas transportation is not affected by the Decontrol Act.

Our sales of natural gas will be affected by intrastate and interstate gas transportation regulation. Beginning in 1985, the FERC adopted
regulatory changes that have significantly altered the transportation and marketing of natural gas. These changes are intended by the FERC to foster competition by, among other things, transforming the role of interstate pipeline companies from
wholesale marketers of natural gas to the primary role of gas transporters. All natural gas marketing by the pipelines is required to divest to a marketing affiliate, which operates separately from the transporter and in direct competition with all
other merchants. As a result of the various omnibus rulemaking proceedings in the late 1980s and the individual pipeline restructuring proceedings of the early to mid-1990s, the interstate pipelines must provide open and nondiscriminatory
transportation and transportation-related services to all producers, natural gas marketing companies, local distribution companies, industrial end users and other customers seeking service. Through similar orders affecting intrastate pipelines that
provide similar interstate services, the FERC expanded the impact of open access regulations to intrastate commerce.

FERC has
pursued other policy initiatives that have affected natural gas marketing. Most notable are (1) the large-scale divestiture of interstate pipeline-owned gas gathering facilities to affiliated or non-affiliated companies; (2) further
development of rules governing the relationship of the pipelines with their marketing affiliates; (3) the publication of standards relating to the use of electronic bulletin boards and electronic data exchange by the pipelines to make available
transportation information on a timely basis and to enable transactions to occur on a purely electronic basis; (4) further review of the role of the secondary market for released pipeline capacity and its relationship to open access service in
the primary market; and (5) development of policy and promulgation of orders pertaining to its authorization of market-based rates (rather than traditional cost-of-service based rates) for transportation or transportation-related services upon
the pipelines demonstration

of lack of market control in the relevant service market. We do not know what effect the FERCs other activities will have on the access to markets, the fostering of competition and the cost
of doing business.

As a result of these changes, sellers and buyers of natural gas have gained direct access to the
particular pipeline services they need and are better able to conduct business with a larger number of counter parties. We believe these changes generally have improved the access to markets for natural gas while, at the same time, substantially
increasing competition in the natural gas marketplace. We cannot predict what new or different regulations the FERC and other regulatory agencies may adopt or what effect subsequent regulations may have on production and marketing of natural gas
from our properties.

In the past, Congress has been very active in the area of natural gas regulation. However, as discussed
above, the more recent trend has been in favor of deregulation and the promotion of competition in the natural gas industry. Thus, in addition to first sales deregulation, Congress also repealed incremental pricing requirements and
natural gas use restraints previously applicable. There are other legislative proposals pending in the Federal and State legislatures which, if enacted, would significantly affect the petroleum industry. At the present time, it is impossible to
predict what proposals, if any, might actually be enacted by Congress or the various state legislatures and what effect, if any, these proposals might have on the production and marketing of natural gas by us. Similarly, and despite the trend toward
federal deregulation of the natural gas industry, whether or to what extent that trend will continue or what the ultimate effect will be on the production and marketing of natural gas by us cannot be predicted.

Our sales of oil and natural gas liquids are not regulated and are at market prices. The price received from the sale of these products will
be affected by the cost of transporting the products to market. Much of that transportation is through interstate common carrier pipelines. Effective as of January 1, 1995, the FERC implemented regulations generally grandfathering all
previously approved interstate transportation rates and establishing an indexing system for those rates by which adjustments are made annually based on the rate of inflation, subject to certain conditions and limitations. These regulations may tend
to increase the cost of transporting oil and natural gas liquids by interstate pipeline, although the annual adjustments may result in decreased rates in a given year. These regulations have generally been approved on judicial review. Every five
years, the FERC will examine the relationship between the annual change in the applicable index and the actual cost changes experienced by the oil pipeline industry. We are not able to predict with certainty what effect, if any, these relatively new
federal regulations or the periodic review of the index by the FERC will have on us.

Federal, state, and local agencies have
promulgated extensive rules and regulations applicable to our oil and natural gas exploration, production and related operations. Oklahoma, Texas and other states require permits for drilling operations, drilling bonds and the filing of reports
concerning operations and impose other requirements relating to the exploration of oil and natural gas. Many states also have statutes or regulations addressing conservation matters including provisions for the unitization or pooling of oil and
natural gas properties, the establishment of maximum rates of production from oil and natural gas wells and the regulation of spacing, plugging and abandonment of such wells. The statutes and regulations of some states limit the rate at which oil
and natural gas is produced from our properties. The federal and state regulatory burden on the oil and natural gas industry increases our cost of doing business and affects our profitability. Because these rules and regulations are amended or
reinterpreted frequently, we are unable to predict the future cost or impact of complying with those laws.

Our operations are
subject to stringent federal, state and local laws and regulations governing protection of the environment. These laws and regulations may require acquisition of permits before certain of our operations may be commenced and may restrict the types,
quantities and concentrations of various substances that can be released into the environment. Planning and implementation of protective measures are required to prevent accidental discharges. Spills of oil, natural gas liquids, drilling fluids, and
other substances may subject us to penalties and cleanup requirements. Handling, storage and disposal of both hazardous and non-hazardous wastes are subject to regulatory requirements.

The federal Clean Water Act, as amended by the Oil Pollution Act, the federal Clean Air Act,
the federal Resource Conservation and Recovery Act, and their state counterparts, are the primary vehicles for imposition of such requirements and for civil, criminal and administrative penalties and other sanctions for violation of their
requirements. In addition, the federal Comprehensive Environmental Response Compensation and Liability Act and similar state statutes impose strict liability, without regard to fault or the legality of the original conduct, on certain classes of
persons who are considered responsible for the release of hazardous substances into the environment. Such liability, which may be imposed for the conduct of others and for conditions others have caused, includes the cost of remedial action as well
as damages to natural resources.

Climate Regulation.Recent scientific studies have
suggested that emissions of certain gases, commonly referred to as greenhouse gases, may be contributing to warming of the Earths atmosphere. As a result there have been a variety of regulatory developments, proposals or
requirements and legislative initiatives that have been introduced in the United States (as well as other parts of the World) that are focused on restricting the emission of carbon dioxide, methane and other greenhouse gases.

In 2007, the United States Supreme Court in Massachusetts, et al. v. EPA, held that carbon dioxide may be regulated as an
air pollutant under the federal Clean Air Act. On December 7, 2009, the EPA responded to the Massachusetts, et al. v. EPA decision and issued a finding that the current and projected concentrations of greenhouse gases in
the atmosphere threaten the public health and welfare of current and future generations, and that certain greenhouse gases from new motor vehicles and motor vehicle engines contribute to the atmospheric concentrations of greenhouse gases and hence
to the threat of climate change.

In June 2009 the U.S. House of Representatives passed the American Clean Energy and Security
Act of 2009 (sometimes referred to as the Waxman-Markey global climate change bill). The bill includes many provisions that would potentially have a significant impact on us as well as our customers. The bill proposes a cap and trade
regime, a renewable portfolio standard, electric efficiency standards, revised transmission policy and mandated investments in plug-in hybrid infrastructure and smart grid technology. Although proposals have been introduced in the U.S. Senate,
including a proposal that would require greater reductions in greenhouse gas emissions than the American Clean Energy and Security Act of 2009, it is uncertain at this time whether, and in what form, legislation will be adopted by the U.S.
Senate. Both President Obama and the Administrator of the EPA have repeatedly indicated their preference for comprehensive legislation to address this issue and create the framework for a clean energy economy.

On September 22, 2009, EPA finalized a rule requiring nation-wide reporting of greenhouse gas emissions beginning January 1, 2010.
The rule applies primarily to large facilities emitting 25,000 metric tons or more of carbon dioxide-equivalent greenhouse gas emissions per year, and to most upstream suppliers of fossil fuels and industrial greenhouse gas, as well as to
manufacturers of vehicles and engines.

We do not know and cannot predict whether any of the proposed legislation or
regulations will be adopted as initially written, if at all, or how legislation or new regulations that may be adopted to address greenhouse gas emissions would impact our business segments. Depending on the final provisions of such rules or
legislation, it is possible that such future laws and regulations could result in increasing our compliance costs or additional operating restrictions as well as those of our customers. It is also possible that such future developments could curtail
the demand for fossil fuels which could adversely affect the demand for our services, which in turn could adversely affect our future results of operations. Likewise we cannot predict with any certainty whether any changes to temperature, storm
intensity or precipitation patterns as a result of climate change (or otherwise) will have a material impact on our operations.

Compliance with applicable environmental requirements has not, to date, had a material effect on the cost of our operations, earnings or competitive position. However, as noted above in connection with our discussion of the regulation of
greenhouse gases, compliance with amended, new or more stringent requirements of existing environmental regulations or requirements may cause us to incur additional costs or subject us to liabilities that may have a material adverse effect on our
results of operations and financial condition.

These statements are based on certain assumptions and analyses made by us in light of our
experience and our perception of historical trends, current conditions and expected future developments as well as other factors we believe are appropriate in the circumstances. However, whether actual results and developments will conform to our
expectations and predictions is subject to a number of risks and uncertainties which could cause actual results to differ materially from our expectations, including:



| |  |  | the risk factors discussed in this report and in the documents we incorporate by reference;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | general economic, market or business conditions;

You should not place undue reliance on any of these forward-looking statements. Except as required by law, we disclaim any current intention to update forward-looking information and to release publicly
the results of any future revisions we may make to forward-looking statements to reflect events or circumstances after the date of this report to reflect the occurrence of unanticipated events.

In order to help provide you with a more thorough understanding of the possible effects of some of these influences on any forward-looking
statements made by us, the following discussion outlines some (but not all) of the factors that in the future could cause our 2010 consolidated results and beyond to differ materially from those that may be presented in any such forward-looking
statement made by or on behalf of us.

Drilling Customer Demand.    With the exception of
the drilling we do for our own account, the demand for our drilling services depends entirely on the needs of third parties. Based on past history, these parties requirements are subject to a number of factors, independent of any subjective
factors, that directly impact the demand for our drilling rigs. These factors include the availability of funds to carry out their drilling operations. For many of these parties, even if they have the funds available, their decision to spend those
funds is often based on the then current prices for oil, NGLs and natural gas. Many of our customers budgets tend to be susceptible to the influences of current price fluctuations. Other factors that affect our ability to work our drilling
rigs are: the weather which, under adverse circumstances, can delay or even cause the abandonment of a project by an operator; the competition faced by us in securing the award of a drilling contract in a given area; our experience and recognition
in a new market area; and the availability of labor to operate our drilling rigs.

As noted elsewhere in this report, the
decline in the economy and commodity prices starting in late 2008 significantly reduced the demand for our drilling rigs. If these conditions continue, we expect that the demand for our drilling rigs will continue to be depressed.

Oil, NGLs and Natural Gas Prices.    The prices we receive for our oil, NGLs and natural gas production
have a direct impact on our revenues, profitability and cash flow as well as our ability to meet our projected financial and operational goals. The prices for natural gas and crude oil are heavily dependent on a number of factors beyond our control,
including:



| |  |  | the demand for oil and/or natural gas;
| | - |  | --------------------------------------



| |  |  | current weather conditions in the continental United States (which can greatly influence the demand for natural gas at any given time as well as the
price we receive for such natural gas);
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | the amount and timing of liquid natural gas imports; and
| | - |  | --------------------------------------------------------



| |  |  | the ability of current distribution systems in the United States to effectively meet the demand for oil and/or natural gas at any given time,
particularly in times of peak demand which may result because of adverse weather conditions.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Oil prices are
extremely sensitive to foreign influences based on political, social or economic underpinnings, any one of which could have an immediate and significant effect on the price and supply of oil.In addition, prices of natural gas, NGLs and oil
are becoming more and more influenced by trading on the commodities markets which, at times, has tended to increase the volatility associated with these prices resulting, at times, in large differences in such prices even on a week-to-week and
month-to-month basis. All of these factors, especially when coupled with the fact that much of our product prices are determined on a daily basis, can, and at times do, lead to wide fluctuations in the prices we receive.

Based on our 2009 production, a $0.10 per Mcf change in what we receive for our natural gas production, without the effect of hedging, would
result in a corresponding $359,000 per month ($4.3 million annualized) change in our pre-tax operating cash flow. A $1.00 per barrel change in our oil price, without the effect of hedging, would have an $101,000 per month ($1.2 million annualized)
change in our pre-tax operating cash flow and a $1.00 per barrel change in our NGLs price, without the effect of hedging, would have a $123,000 per month ($1.5 million annualized) change in our pre-tax operating cash flow. During 2009, substantially
all of our natural gas, crude oil and NGLs volumes were sold at market responsive prices. To help manage our cash flow and capital expenditure requirements, we hedged approximately 77%, 71% and 33% of our 2009 average daily production for natural
gas, crude oil and NGLs, respectively.

In order to reduce our exposure to short-term fluctuations in the price of oil, NGLs
and natural gas, we sometimes enter into hedging arrangements such as swaps and collars. Our hedging arrangements apply to only a portion of our production and provide only partial price protection against declines in oil, NGLs and natural gas
prices. These hedging arrangements may expose us to risk of financial loss and limit the benefit to us of future increases in prices. A more thorough discussion of our hedging arrangements is contained in the Managements Discussion and
Analysis of Financial Condition and Results of Operations section of this report contained in Item 7.

Uncertainty
of Oil, NGLs and Natural Gas Reserves; Ceiling Test.    There are many uncertainties inherent in estimating quantities of oil, NGLs and natural gas reserves and their values, including many factors beyond our control. The
oil, NGLs and natural gas reserve information included in this report represents only an estimate of these reserves. Oil, NGLs and natural gas reservoir engineering is a subjective and an inexact process of estimating underground accumulations of
oil, NGLs and natural gas that cannot be measured in an exact manner. Estimates of economically recoverable oil, NGLs and natural gas reserves depend on a number of variable factors, including historical production from the area compared with
production from other producing areas, and assumptions concerning:



| |  |  | reservoir size;
| | - |  | ---------------



| |  |  | the effects of regulations by governmental agencies;
| | - |  | ----------------------------------------------------



| |  |  | future oil, NGLs and natural gas prices;
| | - |  | ----------------------------------------



| |  |  | future operating costs;
| | - |  | -----------------------



| |  |  | severance and excise taxes;
| | - |  | ---------------------------



| |  |  | development costs; and
| | - |  | ----------------------



| |  |  | workover and remedial costs.
| | - |  | ----------------------------

Some or all of these assumptions may vary considerably from actual results. For these reasons, estimates of the economically recoverable quantities of oil and natural gas attributable to any particular
group of properties,

##### Table of Contents

classifications of those oil, NGLs and natural gas reserves based on risk of recovery, and estimates of the future net cash flows from oil, NGLs and natural gas reserves prepared by different
engineers or by the same engineers but at different times may vary substantially. Accordingly, oil, NGLs and natural gas reserve estimates may be subject to periodic downward or upward adjustments. Actual production, revenues and expenditures with
respect to our oil, NGLs and natural gas reserves will likely vary from estimates, and those variances may be material.

The
information regarding discounted future net cash flows included in this report is not necessarily the current market value of the estimated oil, NGLs and natural gas reserves attributable to our properties. Effective December 31, 2009, as
required by the SEC, the estimated discounted future net cash flows from proved oil, NGLs and natural gas reserves are determined based on the unweighted arithmetic average of the price on the first day of the month for each month within the
12-month period before the end of the reporting period, unless prices were defined by contractual arrangements. Previously, the price used was based on the single-day period-end price. Actual future prices and costs may be materially higher or
lower. Actual future net cash flows are also affected, in part, by the following factors:



| |  |  | the amount and timing of oil and natural gas production;
| | - |  | --------------------------------------------------------



| |  |  | supply and demand for oil and natural gas;
| | - |  | ------------------------------------------



| |  |  | increases or decreases in consumption; and
| | - |  | ------------------------------------------



| |  |  | changes in governmental regulations or taxation.
| | - |  | ------------------------------------------------

In addition, the 10% discount factor, required by the SEC for use in calculating discounted future net cash flows for reporting purposes, is not necessarily the most appropriate discount factor based on
interest rates in effect from time to time and the risks associated with our operations or the oil and natural gas industry in general.

We periodically review the carrying value of our oil and natural gas properties under the full cost accounting rules of the SEC. Under these rules, capitalized costs of proved oil and natural gas
properties may not exceed the present value of estimated future net revenues from proved reserves, discounted at 10%. As of December 31, 2009, application of this ceiling test generally requires pricing future revenue at the
unescalated 12-month average price and requires a write-down for accounting purposes if we exceed the ceiling, even if prices are depressed for only a short period of time. Previously, the price was based on the single-day period-end price. The
revision to the 12-month average price was made to reduce the affect of short-term volatility and seasonality that previously occurred with single-day pricing. Using the 12-month average may or may not result in write-downs that would have been
required had the single-day period-end price been used. We may be required to write down the carrying value of our oil and natural gas properties when oil, NGLs and natural gas prices are depressed or unusually volatile. If a write-down is required,
it would result in a charge to earnings but would not impact our cash flow from operating activities. Once incurred, a write-down of oil and natural gas properties is not reversible.

As a result of these ceiling test rules, we recorded a non-cash ceiling test write down of $282.0 million pre-tax ($175.5 million, net of
tax) during the year ended December 31, 2008 as well as a non-cash ceiling test write down of $281.2 million pre-tax ($175.1 million, net of tax) during the quarter ended March 31, 2009.

We are continually identifying and evaluating opportunities to acquire oil and natural gas properties, including acquisitions that would be
significantly larger than those we have consummated to date. We cannot assure you that we will successfully consummate any acquisition, that we will be able to acquire producing oil and natural gas properties that contain economically recoverable
reserves or that any acquisition will be profitably integrated into our operations.

Debt and Bank
Borrowing.    We have incurred and currently expect to continue to incur substantial working capital expenditures because of the growth in our operations. Historically, we have funded our working capital needs through a
combination of internally generated cash flow and borrowings under our bank credit

##### Table of Contents

facility. We have also, from time to time, obtained funds through equity financing. We currently have, and will continue to have, a certain amount of indebtedness. At December 31, 2009, our
outstanding long-term debt was $30.0 million.

Depending on the amount of our debt, the cash flow needed to satisfy our debt
and the covenants contained in our bank credit facility, such debt could:



| |  |  | limit funds otherwise available for financing our capital expenditures, our drilling program or other activities or cause us to curtail these
activities;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | limit our flexibility in planning for or reacting to changes in our business;
| | - |  | -----------------------------------------------------------------------------



| |  |  | place us at a competitive disadvantage to those of our competitors that are less indebted than we are;
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | make us more vulnerable during periods of low oil, NGLs and natural gas prices or in the event of a downturn in our business; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------



| |  |  | prevent us from obtaining additional financing on acceptable terms or limit amounts available under our existing or any future credit facilities.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------

Our ability to meet our debt obligations depends on our future performance. If the requirements of our
indebtedness are not satisfied, a default could be deemed to occur and our lenders would be entitled to accelerate the payment of the outstanding indebtedness. If that were to occur, we would not have sufficient funds available and probably would
not be able to obtain the financing required to meet our obligations.

The amount of our existing debt, as well as our future
debt, if any, is, to a large extent, based on the costs associated with the projects we undertake at any given time and of our cash flow. Generally, our normal operating costs are those resulting from the drilling of oil and natural gas wells, the
acquisition of producing properties, the costs associated with the maintenance or expansion of our drilling rig fleet, and the operations of our natural gas buying, selling, gathering, processing and treating systems. To some extent, these costs,
particularly the first two are discretionary and we maintain a degree of control regarding the timing or the need to actually incur them. But, in some cases, unforeseen circumstances may arise, such as in the case of an unanticipated opportunity to
make a large acquisition or the need to replace a costly drilling rig component due to an unexpected loss, which could force us to incur additional debt above that which we had expected or forecasted. Likewise, if our cash flow should prove to be
insufficient to cover our current cash requirements we would need to increase our debt either through bank borrowings or otherwise.

We entered into the following interest rate swaps to help manage our exposure to possible future interest rate increases. Under these transactions we have swapped the variable interest rate we would otherwise incur on a portion of our bank
debt for a fixed interest rate. Currently, all of our bank debt is subject to the following interest rate swaps. A more thorough discussion of our hedging or swap arrangements is contained in Item 7 of the Managements Discussion and
Analysis of Financial Condition and Results of Operation section of this report.

RISK FACTORS

There are many other factors that could adversely affect our business. The following discussion describes the material risks currently known
to us. However, additional risks that we do not know about or that we currently view as immaterial may also impair our business or adversely affect the value of our securities. You should carefully consider the risks described below together with
the other information contained in, or incorporated by reference into, this report.

Events in the financial markets and
the economy could adversely affect our operations and financial condition.

As a result of volatility in oil and natural
gas prices and substantial uncertainty in the capital markets due to the uncertain global economic environment, a number of our drilling customers have reduced spending on exploration and development drilling, in addition it is uncertain whether
customers and/or vendors and suppliers will be able to access financing necessary to sustain their operations, fulfill their commitments and/or fund future operations and obligations. The uncertainty in the global economic environment may result in
a decrease in demand for drilling rigs. These conditions could have a material adverse effect on our business, financial condition and results of operations.

If demand for oil and natural gas is reduced, our ability to market as well as produce our oil and natural gas may be negatively affected.

Historically, oil and gas prices have been extremely volatile, with significant increases and significant price drops being experienced from
time to time. In the future, various factors beyond our control will have a significant effect on oil and gas prices. Such factors include, among other things, the domestic and foreign supply of oil and gas, the price of foreign imports, the levels
of consumer demand, the price and availability of alternative fuels, the availability of pipeline capacity and changes in existing and proposed federal regulation and price controls.

The natural gas market is also unsettled due to a number of factors. At times in the past, production from natural gas wells in some
geographic areas of the United States was curtailed for considerable periods of time due to a lack of market demand. When demand for natural gas increased the number of wells being shut-in for lack of demand was reduced. It is possible, however,
that some of our wells may in the future be shut-in or that natural gas will be sold on terms less favorable than might otherwise be obtained should demand for gas lessen in the future. Competition for available markets has been vigorous and there
remains great uncertainty about prices that purchasers will pay. Natural gas surpluses could result in our inability to market natural gas profitably, causing us to curtail production and/or receive lower prices for our natural gas, situations which
would adversely affect us.

Disruptions in the financial markets could affect our ability to obtain financing or refinance
existing indebtedness on reasonable terms and may have other adverse effects.

Commercial-credit market disruptions have
resulted in a tightening of credit markets in the United States. Liquidity in the global-credit markets has been severely contracted by these market disruptions making terms for certain financings less attractive, and in certain cases, have resulted
in the unavailability of certain types of financing. As a result of ongoing credit-market turmoil, we may not be able to obtain debt financing, or refinance existing indebtedness on favorable terms, which could affect operations and financial
performance.

Oil, NGLs and natural gas prices are volatile, and low prices have negatively affected
our financial results and could do so in the future.

Our revenues, operating results, cash flow and future rate of growth
depend substantially on prevailing prices for oil, NGLs and natural gas. Historically, oil, NGLs and natural gas prices and markets have been volatile, and they are likely to continue to be volatile in the future. Any decline in prices in the future
would have a negative impact on our future financial results. Because our oil, NGLs and natural gas reserves are predominantly natural gas, significant changes in natural gas prices would have a particularly large impact on our financial results.

Prices for oil, NGLs and natural gas are subject to wide fluctuations in response to relatively minor changes in the supply
of and demand for oil and natural gas, market uncertainty and a variety of additional factors that are beyond our control. These factors include:



| |  |  | political conditions in oil producing regions, including the Middle East, Nigeria and Venezuela;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | the ability of the members of the Organization of Petroleum Exporting Countries to agree on prices and their ability to maintain production quotas;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the price of foreign oil imports;
| | - |  | ---------------------------------



| |  |  | imports of liquefied natural gas;
| | - |  | ---------------------------------



| |  |  | actions of governmental authorities;
| | - |  | ------------------------------------



| |  |  | the domestic and foreign supply of oil and natural gas;
| | - |  | -------------------------------------------------------



| |  |  | the level of consumer demand;
| | - |  | -----------------------------



| |  |  | U.S. storage levels of natural gas;
| | - |  | -----------------------------------



| |  |  | weather conditions;
| | - |  | -------------------



| |  |  | domestic and foreign government regulations;
| | - |  | --------------------------------------------



| |  |  | the price, availability and acceptance of alternative fuels; and
| | - |  | ----------------------------------------------------------------



| |  |  | overall economic conditions.
| | - |  | ----------------------------

These factors and the volatile nature of the energy markets make it impossible to predict with any certainty the future prices of oil, NGLs and natural gas.

Our contract drilling operations depend on levels of activity in the oil and natural gas exploration and production industry.

Our contract drilling operations depend on the level of activity in oil and natural gas exploration and production in our
operating markets. Both short-term and long-term trends in oil, NGLs and natural gas prices affect the level of that activity. Because oil, NGLs and natural gas prices are volatile, the level of exploration and production activity can also be
volatile. Any decrease from current oil, NGLs and natural gas prices would depress the level of exploration and production activity. This, in turn, would likely result in a decline in the demand for our drilling services and would have an adverse
effect on our contract drilling revenues, cash flows and profitability. As a result, the future demand for our drilling services is uncertain.

The industries in which we operate are highly competitive, and many of our competitors have greater resources than we do.

The drilling industry in which we operate is generally very competitive. Most drilling contracts are awarded on the basis of competitive
bids, which may result in intense price competition. Some of our competitors in the



27

##### Table of Contents

contract drilling industry have greater financial and human resources than we do. These resources may enable them to better withstand periods of low drilling rig utilization, to compete more
effectively on the basis of price and technology, to build new drilling rigs or acquire existing drilling rigs and to provide drilling rigs more quickly than we do in periods of high drilling rig utilization.

The oil and natural gas industry is also highly competitive. We compete in the areas of property acquisitions and oil and natural gas
exploration, development, production and marketing with major oil companies, other independent oil and natural gas concerns and individual producers and operators. In addition, we must compete with major and independent oil and natural gas concerns
in recruiting and retaining qualified employees. Many of our competitors in the oil and natural gas industry have substantially greater resources than we do.

Continued growth through acquisitions is not assured.

In the past, we
have experienced growth in each of our segments, in part, through mergers and acquisitions. The land drilling industry, the exploration and development industry, as well as the gas gathering and processing industry, have experienced significant
consolidation over the past several years, and there can be no assurance that acquisition opportunities will continue to be available. Additionally, we are likely to continue to face intense competition from other companies for available acquisition
opportunities.

There can be no assurance that we will:



| |  |  | be able to identify suitable acquisition opportunities;
| | - |  | -------------------------------------------------------



| |  |  | have sufficient capital resources to complete additional acquisitions;
| | - |  | ----------------------------------------------------------------------



| |  |  | successfully integrate acquired operations and assets;
| | - |  | ------------------------------------------------------



| |  |  | effectively manage the growth and increased size;
| | - |  | -------------------------------------------------



| |  |  | maintain the crews and market share to operate any future drilling rigs we may acquire; or
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | successfully improve our financial condition, results of operations, business or prospects in any material manner as a result of any completed
acquisition.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------

We may incur substantial indebtedness to finance future acquisitions and also may issue equity
securities or convertible securities in connection with any acquisitions. Debt service requirements could represent a significant burden on our results of operations and financial condition and the issuance of additional equity would be dilutive to
existing shareholders. Also, continued growth could strain our management, operations, employees and other resources.

Successful acquisitions, particularly those of oil and natural gas companies or of oil and natural gas properties require an assessment of a number of factors, many of which are beyond our control. These factors include recoverable
reserves, exploration potential, future oil, NGLs and natural gas prices, operating costs and potential environmental and other liabilities. Such assessments are inexact and their accuracy is inherently uncertain.

Our operations have significant capital requirements, and our indebtedness could have important consequences.

We have experienced and may continue to experience substantial working capital needs in the growth of our operations. On February 12,
2010, our outstanding long-term debt was $30.0 million. Our level of indebtedness, the cash flow needed to satisfy our indebtedness and the covenants governing our indebtedness could:



| |  |  | limit funds available for financing capital expenditures, our drilling program or other activities or cause us to curtail these activities;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | limit our flexibility in planning for, or reacting to changes in, our business;
| | - |  | -------------------------------------------------------------------------------



| |  |  | place us at a competitive disadvantage to some of our competitors that are less leveraged than we are;
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | make us more vulnerable during periods of low oil, NGLs and natural gas prices or in the event of a downturn in our business; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------



| |  |  | prevent us from obtaining additional financing on acceptable terms or limit amounts available under our existing or any future credit facilities.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------

Our ability to meet our debt service and other contractual and contingent obligations will depend on our
future performance. In addition, lower oil, NGLs and natural gas prices could result in future reductions in the amount available for borrowing under our credit facility, reducing our liquidity and even triggering mandatory loan repayments.

Our future performance depends on our ability to find or acquire additional oil, NGLs and natural gas reserves that are
economically recoverable.

In general, production from oil and natural gas properties declines as reserves are depleted,
with the rate of decline depending on reservoir characteristics. Unless we successfully replace the reserves that we produce, our reserves will decline, resulting eventually in a decrease in oil and natural gas production and lower revenues and cash
flow from operations. Historically, we have succeeded in increasing reserves after taking production into account through exploration and development. We have conducted these activities on our existing oil and natural gas properties as well as on
newly acquired properties. We may not be able to continue to replace reserves from these activities at acceptable costs. Lower prices of oil and natural gas may further limit the kinds of reserves that can economically be developed. Lower prices
also decrease our cash flow and may cause us to decrease capital expenditures.

We are continually identifying and evaluating
opportunities to acquire oil and natural gas properties, including acquisitions that would be significantly larger than those consummated to date by us. We cannot assure you that we will successfully consummate any acquisition, that we will be able
to acquire producing oil and natural gas properties that contain economically recoverable reserves or that any acquisition will be profitably integrated into our operations.

The competition for producing oil and natural gas properties is intense. This competition could mean that to acquire properties we will have
to pay higher prices and accept greater ownership risks than we have in the past.

Our exploration and production and
mid-stream operations involve a high degree of business and financial risk which could adversely affect us.

Exploration
and development involve numerous risks that may result in dry holes, the failure to produce oil and natural gas in commercial quantities and the inability to fully produce discovered reserves. The cost of drilling, completing and operating wells is
substantial and uncertain. Numerous factors beyond our control may cause the curtailment, delay or cancellation of drilling operations, including:



| |  |  | unexpected drilling conditions;
| | - |  | -------------------------------



| |  |  | pressure or irregularities in formations;
| | - |  | -----------------------------------------



| |  |  | equipment failures or accidents;
| | - |  | --------------------------------



| |  |  | adverse weather conditions;
| | - |  | ---------------------------



| |  |  | compliance with governmental requirements; and
| | - |  | ----------------------------------------------



| |  |  | shortages or delays in the availability of drilling rigs or delivery crews and the delivery of equipment.
| | - |  | ---------------------------------------------------------------------------------------------------------

##### Table of Contents

Exploratory drilling is a speculative activity. Although we may disclose our overall
drilling success rate, those rates may decline. Although we may discuss drilling prospects that we have identified or budgeted for, we may ultimately not lease or drill these prospects within the expected time frame, or at all. Lack of drilling
success will have an adverse effect on our future results of operations and financial condition.

Our mid-stream operations
involve numerous risks, both financial and operational. The cost of developing gathering systems and processing plants is substantial and our ability to recoup these costs is uncertain. Our operations may be curtailed, delayed or cancelled as a
result of many things beyond our control, including:



| |  |  | unexpected changes in the deliverability of natural gas reserves from the wells connected to the gathering systems;
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | availability of competing pipelines in the area;
| | - |  | ------------------------------------------------



| |  |  | equipment failures or accidents;
| | - |  | --------------------------------



| |  |  | adverse weather conditions;
| | - |  | ---------------------------



| |  |  | compliance with governmental requirements;
| | - |  | ------------------------------------------



| |  |  | delays in the development of other producing properties within the gathering systems area of operation; and
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | demand for natural gas and its constituents.
| | - |  | --------------------------------------------

Many of the wells from which we gather and process natural gas are operated by other parties. As a result, we have little control over the operations of those wells which can act to increase our risk.
Operators of those wells may act in ways that are not in our best interests.

Competition for experienced technical
personnel may negatively impact our operations or financial results.

Our continued drilling success and the success of
other activities integral to our operations will depend, in part, on our ability to attract and retain experienced explorationists, engineers and other professionals. Competition for these professionals can be extremely intense, particularly when
the industry is experiencing favorable conditions.

Our hedging arrangements might limit the benefit of increases in oil,
NGLs and natural gas prices.

In order to reduce our exposure to short-term fluctuations in the price of oil, NGLs and
natural gas, we sometimes enter into hedging arrangements. Our hedging arrangements apply to only a portion of our production and provide only partial price protection against declines in oil, NGLs and natural gas prices. These hedging arrangements
may expose us to risk of financial loss and limit the benefit to us of increases in prices.

Estimates of our reserves are
uncertain and may prove to be inaccurate.

There are numerous uncertainties inherent in estimating quantities of proved
reserves and their values, including many factors beyond our control. The reserve data represents only estimates. Reservoir engineering is a subjective and inexact process of estimating underground accumulations of oil and natural gas that cannot be
measured in an exact manner. Estimates of economically recoverable oil, NGLs and natural gas reserves depend on a number of variable factors, including historical production from the area compared with production from other producing areas, and
assumptions concerning:



| |  |  | the effects of regulations by governmental agencies;
| | - |  | ----------------------------------------------------



| |  |  | future oil, NGLs and natural gas prices;
| | - |  | ----------------------------------------

| |  |  | future operating costs;
| | - |  | -----------------------



| |  |  | severance and excise taxes;
| | - |  | ---------------------------



| |  |  | development costs; and
| | - |  | ----------------------



| |  |  | workover and remedial costs.
| | - |  | ----------------------------

Some or all of these assumptions may vary considerably from actual results. For these reasons, estimates of the economically recoverable quantities of oil and natural gas attributable to any particular
group of properties, classifications of those reserves based on risk of recovery, and estimates of the future net cash flows from reserves prepared by different engineers or by the same engineers but at different times may vary substantially.
Accordingly, reserve estimates may be subject to downward or upward adjustment. Actual production, revenues and expenditures with respect to our reserves will likely vary from estimates, and those variances may be material.

The information regarding discounted future net cash flows should not be considered as the current market value of the estimated oil, NGLs
and natural gas reserves attributable to our properties. As required by the SEC, the estimated discounted future net cash flows from proved reserves are based on prices on the first day of the month for each month within the 12-month period before
the end of the reporting period and costs as of the date of the estimate, while actual future prices and costs may be materially higher or lower. Actual future net cash flows also will be affected by the following factors:



| |  |  | the amount and timing of actual production;
| | - |  | -------------------------------------------



| |  |  | supply and demand for oil and natural gas;
| | - |  | ------------------------------------------



| |  |  | increases or decreases in consumption; and
| | - |  | ------------------------------------------



| |  |  | changes in governmental regulations or taxation.
| | - |  | ------------------------------------------------

In addition, the 10% per year discount factor, which is required by the SEC to be used in calculating discounted future net cash flows for reporting purposes, is not necessarily the most appropriate
discount factor based on interest rates in effect from time to time and risks associated with our operations or the oil and natural gas industry in general.

If oil, NGLs and natural gas prices decrease or are unusually volatile, we may be required to take write-downs of our oil and natural gas properties, the carrying value of our drilling rigs or our
natural gas gathering and processing systems.

We periodically review the carrying value of our oil and natural gas
properties under the full cost accounting rules of the SEC. Under these rules, capitalized costs of proved oil and natural gas properties may not exceed the present value of estimated future net revenues from proved reserves, discounted at
10% per year. Effective December 31, 2009, application of the ceiling test generally requires pricing future revenue at the unweighted arithmetic average of the price on the first day of month for each month within the 12-month period
prior to the end of the reporting period, unless prices were defined by contractual arrangements, and requires a write-down for accounting purposes if the ceiling is exceeded, even if prices were depressed for only a short period of time.
Previously, the price was based on the single-day period-end price. The revision to the 12-month average price was made to reduce the affect of short-term volatility and seasonality that previously occurred with single-day pricing. Using the
12-month average may or may not result in write-downs that would have been required had the single-day period-end price been used. We may be required to write down the carrying value of our oil and natural gas properties when oil, NGLs and natural
gas prices are depressed or unusually volatile. If a write-down is required, it would result in a charge to earnings, but would not impact cash flow from operating activities. Once incurred, a write-down of oil and natural gas properties is not
reversible at a later date.

##### Table of Contents

Our drilling equipment, transportation equipment, gas gathering and processing systems and
other property and equipment are carried at cost. We are required to periodically test to see if these values, including associated goodwill and other intangible assets, have been impaired whenever events or changes in circumstances suggest the
carrying amount may not be recoverable. If any of these assets are determined to be impaired, the loss is measured as the amount by which the carrying amount of the asset exceeds its fair value. An estimate of fair value is based on the best
information available, including prices for similar assets. Changes in these estimates could cause us to reduce the carrying value of property, equipment and related intangible assets. Once these values have been reduced, they are not reversible.

Our operations present inherent risks of loss that, if not insured or indemnified against, could adversely affect our
results of operations.

Our drilling operations are subject to many hazards inherent in the drilling industry, including
blowouts, cratering, explosions, fires, loss of well control, loss of hole, damaged or lost drilling equipment and damage or loss from inclement weather. Our exploration and production and mid-stream operations are subject to these and similar
risks. Any of these events could result in personal injury or death, damage to or destruction of equipment and facilities, suspension of operations, environmental damage and damage to the property of others. Generally, drilling contracts provide for
the division of responsibilities between a drilling company and its customer, and we seek to obtain indemnification from our drilling customers by contract for some of these risks. To the extent that we are unable to transfer these risks to drilling
customers by contract or indemnification agreements (or to the extent we assume obligations of indemnity or assume liability for certain risks under our drilling contracts), we seek protection from some of these risks through insurance. However,
some risks are not covered by insurance and we cannot assure you that the insurance we do have or the indemnification agreements we have entered into will adequately protect us against liability from all of the consequences of the hazards described
above. The occurrence of an event not fully insured or indemnified against, or the failure of a customer to meet its indemnification obligations, could result in substantial losses. In addition, we cannot assure you that insurance will be available
to cover any or all of these risks. Even if available, the insurance might not be adequate to cover all of our losses, or we might decide against obtaining that insurance because of high premiums or other costs.

In addition, we are not the operator of many of our wells. As a result, our operating risks for those wells and our ability to influence the
operations for those wells are less subject to our control. Operators of those wells may act in ways that are not in our best interests.

Governmental and environmental regulations could adversely affect our business.

Our business is subject to federal, state and local laws and regulations on taxation, the exploration for and development, production and marketing of oil and natural gas and safety matters. Many laws and regulations require drilling
permits and govern the spacing of wells, rates of production, prevention of waste, unitization and pooling of properties and other matters. These laws and regulations have increased the costs of planning, designing, drilling, installing, operating
and abandoning our oil and natural gas wells and other facilities. In addition, these laws and regulations, and any others that are passed by the jurisdictions where we have production, could limit the total number of wells drilled or the allowable
production from successful wells, which could limit our revenues.

We are (or could become) subject to complex environmental
laws and regulations adopted by the various jurisdictions where we own or operate. We could incur liability to governments or third parties for discharges of oil, natural gas or other pollutants into the air, soil or water, including responsibility
for remedial costs. We could potentially discharge these materials into the environment in any number of ways including the following:



| |  |  | from a well or drilling equipment at a drill site;
| | - |  | --------------------------------------------------



| |  |  | from gathering systems, pipelines, transportation facilities and storage tanks;
| | - |  | -------------------------------------------------------------------------------

| | - |  | ------------------------------------------------------------------------------------------



| |  |  | blowouts, cratering and explosions.
| | - |  | -----------------------------------

Because the requirements imposed by laws and regulations are frequently changed, we cannot assure you that laws and regulations enacted in the future, including changes to existing laws and regulations,
will not adversely affect our business. The current Congress and White House administration may impose or change laws and regulations that will adversely affect our business. With the trend toward stricter standards, greater regulation and more
extensive permit requirements, our risks related to environmental matters and our environmental expenditures could increase in the future. In addition, because we acquire interests in properties that have been operated in the past by others, we may
be liable for environmental damage caused by the former operators, which liability could be material.

Any future
implementation of price controls on oil, NGLs and natural gas would affect our operations.

Certain groups have asserted
efforts to have the United States Congress impose some form of price controls on either natural gas, oil or both. There is no way at this time to know what result these efforts will have nor, if implemented, their effect on our operations. However,
it is possible that these efforts, if successful, would serve to limit the amount that we might be able to get for our future oil and natural gas production. Any future limits on the price of oil, NGLs and natural gas could also result in adversely
affecting the demand for our drilling services.

Our shareholders rights plan and provisions of Delaware law and our
by-laws and charter could discourage change in control transactions and prevent shareholders from receiving a premium on their investment.

Our by-laws and charter provide for a classified board of directors with staggered terms and authorizes the board of directors to set the terms of preferred stock. In addition, our charter and Delaware
law contain provisions that impose restrictions on business combinations with interested parties. We have also adopted a shareholders rights plan. Because of our shareholders rights plan and these provisions of our by-laws, charter and
Delaware law, persons considering unsolicited tender offers or other unilateral takeover proposals may be more likely to negotiate with our board of directors rather than pursue non-negotiated takeover attempts. As a result, these provisions may
make it more difficult for our shareholders to benefit from transactions that are opposed by an incumbent board of directors.

New technologies may cause our current exploration and drilling methods to become obsolete, resulting in an adverse effect on our production.

Our industry is subject to rapid and significant advancements in technology, including the introduction of new products and services using new technologies. As competitors use or develop new technologies,
we may be placed at a competitive disadvantage, and competitive pressures may force us to implement new technologies at a substantial cost. In addition, competitors may have greater financial, technical and personnel resources that allow them to
enjoy technological advantages and may in the future allow them to implement new technologies before we can. We cannot be certain that we will be able to implement technologies on a timely basis or at a cost that is acceptable to us. One or more of
the technologies that we currently use or that we may implement in the future may become obsolete, and we may be adversely affected.

We may be affected by climate change and market or regulatory responses to climate change.

Climate change,
including the impact of potential global warming regulations, could have a material adverse effect on our results of operations, financial condition, and liquidity. Restrictions, caps, taxes, or other controls

##### Table of Contents

on emissions of greenhouse gasses, including diesel exhaust, could significantly increase our operating costs. Restrictions on emissions could also affect our customers that (a) use
commodities that we carry to produce energy, (b) use significant amounts of energy in producing or delivering the commodities we carry, or (c) manufacture or produce goods that consume significant amounts of energy or burn fossil fuels,
including chemical producers, farmers and food producers, and automakers and other manufacturers. Significant cost increases, government regulation, or changes of consumer preferences for goods or services relating to alternative sources of energy
or emissions reductions could materially affect the markets for the commodities associated with our business, which in turn could have a material adverse effect on our results of operations, financial condition, and liquidity. Government incentives
encouraging the use of alternative sources of energy could also affect certain of our customers and the markets for certain of the commodities associated with our business in an unpredictable manner that could alter our business activities. Finally,
we could face increased costs related to defending and resolving legal claims and other litigation related to climate change and the alleged impact of our operations on climate change. Any of these factors, individually or in operation with one or
more of the other factors, or other unforeseen impacts of climate change could reduce the amount of business activity we conduct and have a material adverse effect on our results of operations, financial condition, and liquidity.

The results of our operations depend on our ability to transport oil and gas production to key markets.

The marketability of our oil and natural gas production depends in part on the availability, proximity and capacity of pipeline systems. The
unavailability of or lack of available capacity on these systems and facilities could result in the shut-in of producing wells or the delay or discontinuance of development plans for properties. 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.

The loss of one or a number of our larger customers could have a material adverse effect on our financial
condition and results of operations.

During 2009, our largest customer, Questar Corporation accounted for approximately
35% of our contract drilling revenues. No other third party customer accounted for 10% or more of our contract drilling revenues. Any of our customers may choose not to use our services and the loss of one or a number of our larger customers could
have a material adverse effect on our financial condition and results of operations.

Our mid-stream segment depends on
certain natural gas producers and pipeline operators for a significant portion of its supply of natural gas and NGLs. The loss of any of these producers could result in a decline in our volumes and revenues.

We rely on certain natural gas producers for a significant portion of our natural gas and NGL supply. While some of these producers are
subject to long-term contracts, we may be unable to negotiate extensions or replacements of these contracts on favorable terms, if at all. The loss of all or even a portion of the natural gas volumes supplied by these producers, as a result of
competition or otherwise, could have a material adverse effect on our mid-stream segment unless we were able to acquire comparable volumes from other sources.

The counterparties to our commodity derivative contracts may not be able to perform their obligations to us, which could materially affect our cash flows and results of operations.

To reduce our exposure to adverse fluctuations in the prices of oil and natural gas, we currently, and may in the future, enter into
commodity derivative contracts for a significant portion of our forecasted oil and natural gas production. The extent of our commodity price exposure is related largely to the effectiveness and scope of our derivative activities, as well as to the
ability of counterparties under our commodity derivative contracts to satisfy their obligations to us. The worldwide financial and credit crisis may have adversely affected the ability of these

counterparties to fulfill their obligations to us. If one or more of our counterparties is unable or unwilling to make required payments to us under our commodity derivative contracts, it could
have a material adverse effect on our financial condition and results of operations.

Reliance on management.

We depend greatly on the efforts of our executive officers and other key employees to manage our operations. The
loss or unavailability of any of our executive officers or other key employees could have a material adverse effect on our business.

We are subject to various claims and litigation that could ultimately be resolved against us requiring material future cash payments and/or future material charges against our operating income and materially impairing our financial
position.

The nature of our business makes us highly susceptible to claims and litigation. We are subject to various
existing legal claims and lawsuits, which could have a material adverse effect on our consolidated financial position, results of operations or cash flows. Any claims or litigation, even if fully indemnified or insured, could negatively affect our
reputation among our customers and the public, and make it more difficult for us to compete effectively or obtain adequate insurance in the future.

Panola Independent School District No. 4, et al.v. Unit Petroleum Company, No. CJ-07-215, District Court of Latimer County, Oklahoma.

Panola Independent School District No. 4, Michael Kilpatrick, Gwen Grego, Carla Lessel, Thelma Christine Pate, Juanita Golightly,
Melody Culberson and Charlotte Abernathy are the Plaintiffs in this case and are royalty owners in oil and gas drilling and spacing units for which the companys exploration segment distributes royalty. The Plaintiffs central
allegation is that the companys exploration segment has underpaid royalty obligations by deducting post-production costs or marketing related fees. Plaintiffs also seek to pursue the case as a class action on behalf of persons who receive
royalty from us for our Oklahoma production. We have asserted several defenses including that the deductions are permitted under Oklahoma law. We have also asserted that the case should not be tried as a class action due to the materially
different circumstances that determine what, if any, deductions are taken for each lease. On December 16, 2009, the trial court entered its order certifying the class. We have appealed the trial courts order. It is not currently known
when the appeal will be acted on by the Oklahoma Appellate courts. Adjudication of the merits of the Plaintiffs claims is stayed until the appeal of the class certification order is decided.

|Item 7. | Managements Discussion and Analysis of Financial Condition and Results of Operations
|------- | -------------------------------------------------------------------------------------

Please read the following discussion of our financial condition and results of operations in conjunction with the consolidated financial
statements and related notes included in Item 8 of this report.

General

We were founded in 1963 as a contract drilling company. Today, we operate, manage and analyze our results of operations through our three
principal wholly owned business segments:



| |  |  | Contract Drillingcarried out by our subsidiary Unit Drilling Company and its subsidiaries. This segment contracts to drill onshore oil and
natural gas wells for others and for our own account.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Oil and Natural Gascarried out by our subsidiary Unit Petroleum Company. This segment explores, develops, acquires and produces oil and
natural gas properties for our own account.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Mid-Streamcarried out by our subsidiary Superior Pipeline Company, L.L.C. and its subsidiary. This segment buys, sells, gathers, processes
and treats natural gas for third parties and for our own account.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Business Outlook

As discussed in other parts of this report, the success of our consolidated business as well as each of our three main operating segments
depend, on a large part, on the prices received for our natural gas, natural gas liquids and oil production and the demand for oil and natural gas as well as for our drilling rigs which, in turn, influences the amounts we can charge for the use of
those drilling rigs. While to date all of our operations (with the exception of a minor amount of production in Canada) are located within the United States, events outside the United States can and do impact us and our industry.

In addition to their direct impact on us, lower commodity prices for sustained periods of time could also impact the liquidity of some of
our industry partners and customers, which, in turn, might limit their ability to meet their financial obligations to us.

The slowdown in the United States and world economies starting in late 2008 has resulted (to
varying degrees) in a reduction in the demand for oil and natural gas products by those industries and consumers that use those products in their business operations. The long-term impact on our business and financial results as a consequence of the
volatility in oil and natural gas prices and the global economic downturn is uncertain.

The following table reflects the
significant fluctuations in the prices for oil and natural gas:

As noted in the table
above, oil and natural gas prices declined significantly after their July 2008 levels before they began to reverse their downward trend by the end of 2009. Our initial 2010 operating budget is based on oil and natural gas prices averaging $72.00 per
Bbl and $5.30 per Mcf, respectively, for the year. We expect to fund our 2010 operating budget using internally generated cash flow and to a lesser extent from borrowings under our credit facility.

Our 2010 capital budget for all of our business segments forecasts a 60% increase over our 2009 capital expenditures. Our oil and natural
gas segments capital budget is $365.0 million, a 58% increase over 2009. With the reduction in well costs that occurred during 2009, we are planning an aggressive drilling program in 2010 with a significant portion of the wells being
horizontal. Our drilling segments capital budget is $76.0 million, a 12% increase over 2009. Our focus will be on refurbishing and upgrading several of our existing drilling rigs in our fleet in order that those rigs can be used in horizontal
drilling operations. Our mid-stream segments capital budget is $53.0 million, a 435% increase over 2009. The increase is due to anticipated drilling activity by operators in the areas of our existing gathering systems resulting in new well
connections as well as adding an additional processing facility in the Texas Panhandle to accommodate the increased need resulting from the drilling activity of our oil and natural gas segment.

Executive Summary

Contract Drilling

Our fourth quarter 2009 utilization rate was 28%,
compared to 26% and 74% in the third quarter of 2009 and the fourth quarter 2008, respectively. Dayrates for the fourth quarter of 2009 averaged $14,708, a decrease of 4% from the third quarter of 2009 and 24% from the fourth quarter of 2008. Direct
profit (contract drilling revenue less contract drilling operating expense) decreased 14% from the third quarter of 2009 and 77% from the fourth quarter of 2008, primarily due to the decrease in utilization. Operating cost per day increased 2% from
the third quarter of 2009 and increased 8% from the fourth quarter of 2008. The decrease from the third quarter 2009 was primarily due to increases in the per day direct cost and general and administrative expenses. The increase from the fourth
quarter of 2008 was primarily attributable to certain indirect drilling costs being spread over fewer utilization days partially offset by decreased per day direct cost and decreases in workers compensation costs. In the third and fourth
quarters of 2008, prices for oil and natural gas decreased substantially. While oil prices tended to increase during 2009, natural gas prices remained depressed through most of 2009, before they began to increase during the fourth quarter of 2009.
With anticipated increases to 2010 drilling activity and spending by our customers we may see an increase in our 2010 drilling rig utilization as compared to levels at the end of 2009.

During 2009, we sold three mechanical drilling rigs and acquired one new 1,500 horsepower diesel electric drilling rig for $13.2 million.
These transactions brought our total fleet to 130 drilling rigs at December 31, 2009.

Our anticipated 2010 capital
expenditures for this segment are $76.0 million.

We agreed to delay the delivery of a new 1,500 horsepower diesel electric
drilling rig that was to have been delivered to North Dakota under a long term contract in the first quarter of 2009. Under that agreement, our

##### Table of Contents

customer agreed to make monthly payments pending the future delivery of the rig. Our customer has now advised us to prepare the rig for mobilization to North Dakota for use in their drilling
program during the first quarter of 2010.

In January and February 2010, our contract drilling segment entered into contracts
to sell eight of its idle mechanical drilling rigs to an unaffiliated third party. These drilling rigs ranged in horse power from 800 to 1,000. The closing on three of these drilling rigs occurred in February. Three more are scheduled to
close during the first quarter of 2010 with the last transaction for the remaining two rigs anticipated to close during the second quarter of 2010. Proceeds from the sale of all the drilling rigs will be $23.9 million resulting in an estimated gain
of $6.1 million. The proceeds from this sale will be used to refurbish and upgrade additional rigs in our fleet in order that those rigs can be used in horizontal drilling operations. We also placed into service in our Rocky Mountain division a
1,500 horsepower, diesel-electric drilling rig that previously had been placed on hold during 2009 by our customer. At completion of the sale of the eight rigs and with the additional rig recently placed into service, this segment will have 123
drilling rigs in its fleet.

Oil and Natural Gas

Fourth quarter 2009 production from our oil and natural gas segment was 156,000 Mcfe per day, a 2% decrease over the third quarter of 2009
and a 15% decrease over the fourth quarter of 2008. The decreases are primarily due to a significant reduction in the number of wells drilled during the year and the fourth quarter of 2008 and to a lesser extent the curtailment and shut-in of
third-party plants of approximately 1.2 Bcfe of production during 2009.

Oil and natural gas revenues increased 2% from the
third quarter of 2009 and decreased 16% from the fourth quarter of 2008. Our oil, natural gas and NGL prices in the fourth quarter of 2009, increased 3%, 2% and 13%, respectively, from the third quarter of 2009 and our oil and NGL prices decreased
21% and 1%, respectively, from the fourth quarter of 2008 while natural gas prices increased 4%. Direct profit (oil and natural gas revenues less oil and natural gas operating expense) decreased 4% from the third quarter of 2009 and decreased 19%
from the fourth quarter of 2008. The decrease from the third quarter 2009 was primarily attributable to an increase in production taxes and the fourth quarter 2008 primarily resulted from a decrease in production and oil prices. Operating cost per
Mcfe produced increased 23% from the third quarter of 2009 and increased 13% from the fourth quarter of 2008. We hedged 71% of our 2009 average daily oil production, approximately 77% of our 2009 average natural gas production and approximately 33%
of our 2009 average NGL production to help manage our cash flow and capital expenditure requirements. Currently for 2010, we have hedged 71% of our average daily oil production (based on our 2009 production) and approximately 69% of our average
daily natural gas production (based on our 2009 production).

In March 2009, we incurred a non-cash ceiling test write down of
our oil and natural gas properties of $281.2 million pre-tax ($175.1 million net of tax) due to low commodity prices at the end of the first quarter. At December 31, 2009, the 12-month average of commodity prices, including the discounted value
of our commodity hedges, were at levels that did not require us to record a year-end write-down of our oil and natural gas properties. Previously, the price was based on the single-day period-end price. The revision to the 12-month average price was
made to reduce the affect of short-term volatility and seasonality that previously occurred with single-day pricing. Using the 12-month average may or may not result in write-downs that would have been required had the single-day period-end price
been used. Should the 12-month average for commodity prices decline below that existing at year-end, including the discounted value of our commodity hedges, an additional write-down of the carrying value of our oil and natural gas properties could
be required in future periods.

Our estimated production for 2010 is approximately 66.0 to 67.0 Bcfe, an increase of 9% to 10%
from our 2009 production. We currently anticipate that we will participate in the drilling of approximately 175 wells during 2010, an increase of 84% over 2009. Our anticipated 2010 capital expenditures for this segment are $365.0 million.

In the third and fourth quarter of 2008, commodity prices decreased substantially and
remained at low levels through the third quarter of 2009. As a result of these lower commodity prices and the relatively high costs for well drilling services, we decided to reduce our drilling activity during the fourth quarter of 2008 and
continued to do so through the second quarter of 2009. We began increasing activity during the third quarter of 2009 and plan to continue to increase activity throughout 2010.

Mid-Stream

Fourth quarter 2009 liquids sold per day increased 5% from the third quarter of 2009 and increased 34% from the fourth quarter of 2008. Liquids sold per day increased from the third quarter of 2009 primarily due to operating the processing
plants in an ethane rejection mode during the third quarter of 2009 due to an extremely low ethane price, and increased from the fourth quarter of 2008 primarily as the result of upgrades and expansions to existing plants. Gas processed per day was
essentially unchanged from the third quarter of 2009 and increased 7% over the fourth quarter of 2008. In 2008, we upgraded several of our existing processing facilities and added three processing plants which was the primary reason for increased
volumes. Gas gathered per day decreased 1% from the third quarter of 2009 and 6% from the fourth quarter of 2008 primarily from our Southeast Oklahoma gathering system experiencing natural production declines associated with connected wells.

NGL prices in the fourth quarter of 2009 increased 41% from the price received in the third quarter of 2009 and 9% over the
price received in the fourth quarter of 2008. The price of liquids as compared to natural gas affects the revenue in our mid-stream operations and determines the fractionation spread which is the difference in the value received for the NGLs
recovered from natural gas in comparison to the amount received for the equivalent MMBtus of natural gas if unprocessed. We currently do not have any fractionation spread hedges in place for 2010 and beyond.

Direct profit (mid-stream revenues less mid-stream operating expense) increased 45% from the third quarter of 2009 and increased 138% from
the fourth quarter of 2008. The increase from the third quarter 2009 and the fourth quarter 2008 resulted primarily from increased commodity prices and to a lesser extent an increase in volumes. Total operating cost for our mid-stream segment
increased 40% from the third quarter of 2009 and increased 13% from the fourth quarter of 2008 due primarily to the increase in the price paid for the purchase of natural gas. Our anticipated capital expenditures for 2010 for this segment are $53.0
million. For 2010, we anticipate an increase in well connections due to anticipated drilling activity by operators in the areas of our existing gathering systems as well as adding an additional processing facility to accommodate the increased
drilling activity of our oil and natural gas segment.

Critical Accounting Policies and Estimates

Summary

In this
section, we identify those critical accounting policies we follow in preparing our financial statements and related disclosures. Many of these policies require us to make difficult, subjective and complex judgments in the course of making estimates
of matters that are inherently imprecise. Some accounting policies involve judgments and uncertainties to such an extent that there is reasonable likelihood that materially different amounts could have been reported under different conditions, or if
different assumptions had been used. We evaluate our estimates and assumptions on a regular basis. We base our estimates on historical experience and various other assumptions that we believe are reasonable under the circumstances, the results of
which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates and assumptions used in preparation of our financial
statements. In the following discussion we will attempt to explain the nature of these estimates, assumptions and judgments, as well as the likelihood that materially different amounts would be reported in our financial statements under different
conditions or using different assumptions.

Significant Estimates and Assumptions

Full Cost Method of
Accounting for Oil, NGLs and Natural Gas Properties.The determination of our oil, NGLs and natural gas reserves is a very subjective process. It entails estimating underground accumulations of oil, NGLs and natural gas
that cannot be measured in an exact manner. The degree of accuracy of these estimates depends on a number of factors, including, the quality and availability of geological and engineering data, the precision of the interpretations of that data, and
individual judgments. Each year, we hire an independent petroleum engineering firm to audit our internal evaluation of our reserves. The wells or locations for which

##### Table of Contents

estimates of reserves were audited were those that comprised the top 85% of the total proved discounted future net cash flows based on the unescalated pricing policy of the SEC as taken from
reserve and income projections prepared by us as of December 31, 2009. Included in Part I, Item 1 of this report are the qualifications of our independent petroleum engineering firm and the companys personnel responsible for the
preparation of our reserve reports.

As a general rule, the degree of accuracy of oil, NGLs and natural gas reserve estimates
varies with the reserve classification and the related accumulation of available data, as shown in the following table:



|                               |  |                                                                    |  |                   
|------------------------------ |  | ------------------------------------------------------------------ |  | ------------------
|Type of Reserves               |  | Nature of Available Data                                           |  | Degree of Accuracy
|Proved undeveloped             |  | Data from offsetting wells, seismic data                           |  | Less accurate

|Proved developed producing     |  | The above as well as production history, pressure data over time   |  | Most accurate     

Assumptions as to future
oil, NGLs and natural gas prices and operating and capital costs also play a significant role in estimating oil, NGLs and natural gas reserves and the estimated present value of the cash flows to be received from the future production of those
reserves. Volumes of recoverable reserves are influenced by the assumed prices and costs due to what is known as the economic limit (that point in the future when the projected costs and expenses of producing recoverable oil, NGLs and natural gas
reserves is greater than the projected revenues from the oil, NGLs and natural gas reserves). But more significantly, the estimated present value of the future cash flows from our oil, NGLs and natural gas reserves is extremely sensitive to prices
and costs, and may vary materially based on different assumptions. Effective December 31, 2009, SEC requirements require that the pricing we use be the unweighted arithmetic average of the price on the first day of the month for each month
within the 12-month period before the end of the reporting period, unless prices were defined by contractual arrangements. Previously, the price was based on the single-day period-end price. The revision to the 12-month average price was made to
reduce the affect of short-term volatility and seasonality that previously occurred with single-day pricing. Using the 12-month average may or may not result in write-downs that would have been required had the single-day period-end price been used.
The transition to the new rule in 2009 resulted in significantly lower prices being used in year-end reporting as compared to what would have been used had the single-day year-end prices still been in effect. The prices used in our reserve estimates
were $3.86 per Mcf for natural gas, $61.18 per Bbl for oil, and $34.44 per Bbl for NGLs, as opposed to $5.79 per Mcf for natural gas, $79.36 per Bbl for oil and $55.13 per Bbl for NGLs, which would have been the prices under the old SEC rules. Our
reserves under the new rules are 25 bcfe lower than what they would have been under the old rules.

We compute our provision
for DD&A on a units-of-production method. Each quarter, we use the following formulas to compute the provision for DD&A for our producing properties:



| |  |  | DD&A Rate = Unamortized Cost / Beginning of Period Reserves
| | - |  | -----------------------------------------------------------



| |  |  | Provision for DD&A = DD&A Rate x Current Period Production
| | - |  | ----------------------------------------------------------

Oil, NGLs and natural gas reserve estimates have a significant impact on our DD&A rate. If reserve estimates for a property or group of
properties are revised downward in the future, the DD&A rate will increase as a result of the revision. Alternatively, if reserve estimates are revised upward, the DD&A rate will decrease. Based on our 2009 production level of 60,709,000
equivalent Mcf, a 5% decline in the amount of our 2009 oil, NGLs and natural gas reserves would increase our DD&A rate by $0.09 per Mcfe and would decrease pre-tax income by $5.5 million annually. A 5% increase in the amount of our 2009 oil,
NGLs and natural gas reserves would decrease our DD&A rate by $0.08 per Mcfe and would increase pre-tax income by $4.9 million annually.

Our DD&A expense on our oil and natural gas properties is calculated each quarter
utilizing period end reserve quantities. The new SEC oil and gas reserves measurement and disclosure rules that went into effect as of December 31, 2009 impacted our DD&A expense for the fourth quarter of 2009, increasing DD&A expense
by $1.2 million (or $0.02 per share) for the quarter and year ended December 31, 2009.

We account for our oil and
natural gas exploration and development activities using the full cost method of accounting. Under this method, all costs incurred in the acquisition, exploration and development of oil and natural gas properties are capitalized. At the end of each
quarter, the net capitalized costs of our oil and natural gas properties are limited to the lower of unamortized cost or a ceiling. The ceiling is defined as the sum of the present value (using a 10% discount rate) of the estimated future net
revenues from our proved reserves based on the unescalated 12-month average price (effective December 31, 2009) on our oil, NGLs and natural gas adjusted for any cash flow hedges, plus the lower of cost or estimated fair value of unproved
properties not included in the costs being amortized, less related income taxes. If the net capitalized costs of our oil and natural gas properties exceed the ceiling, we are required to write-down the excess amount. A ceiling test write-down is a
non-cash charge to earnings. If required, it reduces earnings and impacts shareholders equity in the period of occurrence and results in lower depreciation, depletion and amortization expense in future periods. Once incurred, a write-down
cannot be reversed.

The risk that we will be required to write-down the carrying value of our oil and natural gas properties
increases when oil, NGLs and natural gas prices are depressed or if we have large downward revisions in our estimated proved oil, NGLs and natural gas reserves. Application of these rules during periods of relatively low oil or natural gas prices,
even if temporary, increases the chance of a ceiling test write-down. Based on the 12-month 2009 average unescalated prices of $61.18 per barrel of oil, $34.44 per barrel of NGLs and $3.86 per Mcf of natural gas, for the estimated life of the
respective properties, the unamortized cost of our oil and natural gas properties did not exceeded the ceiling of our proved oil, NGL and natural gas reserves. Previously, the price was based on the single-day period-end price. The revision to the
12-month average price was made to reduce the affect of short-term volatility and seasonality that previously occurred with single-day pricing. Using the 12-month average may or may not result in write-downs that would have been required had the
single-day period-end price been used. Oil, NGLs and natural gas prices remain volatile and any significant declines below prices used in the reserve evaluation could result in a ceiling test write-down in the future.

Derivative instruments qualifying as cash flow hedges are to be included in the computation of limitation on capitalized costs. Our
qualifying cash flow hedges as of December 31, 2009, which consisted of swaps and collars, covered 36.5 Bcfe in 2010. The effect of these cash flow hedges was a $88.5 million pre-tax increase in the value of our oil and natural gas properties.
Our oil and natural gas hedging activities are discussed in Note 13 of our Notes to Consolidated Financial Statements.

We use
the sales method for recording natural gas sales. This method allows for the recognition of revenue, which may be more or less than our share of pro-rata production from certain wells. Our policy is to expense our pro-rata share of lease operating
costs from all wells as incurred. The expenses relating to the wells in which we have an imbalance are not material.

Accounting for ARO for Oil, NGLs and Natural Gas Properties.We record the fair value of liabilities associated with the retirement of assets having a long life. In our case, when the reserves in each of our
oil or gas wells deplete or otherwise become uneconomical, we are required to incur costs to plug and abandon the wells. These costs are recorded in the period in which the liability is incurred (at the time the wells are drilled or acquired). We do
not have any assets restricted for the purpose of settling these ARO liabilities. Our engineering staff uses historical experience to determine the estimated plugging costs taking into account the type of well (either oil or natural gas), the depth
of the well and physical location of the well to determine the estimated plugging costs.

Accounting for Impairment of
Long-Lived Assets.Drilling equipment, transportation equipment, gas gathering and processing systems and other property and equipment are carried at cost less accumulated

depreciation. Renewals and enhancements are capitalized while repairs and maintenance are expensed. Realization of the carrying value of property and equipment is reviewed for possible impairment
whenever events or changes in circumstances suggest that these carrying amounts may not be recoverable. Assets are determined to be impaired if a forecast of undiscounted estimated future net operating cash flows directly related to the asset,
including disposal value if any, is less than the carrying amount of the asset. If any asset is determined to be impaired, the loss is measured as the amount by which the carrying amount of the asset exceeds its fair value. The estimate of fair
value is based on the best information available, including prices for similar assets. Changes in these estimates could cause us to reduce the carrying value of property and equipment. An estimate of the impact to our earnings if other assumptions
had been used is not practicable because of the significant number of assumptions that would be involved in the estimates. No significant impairments were recorded at December 31, 2009, 2008 or 2007.

Goodwill.Goodwill represents the excess of the cost of acquisitions over the fair value of the net assets
acquired. An annual impairment test is performed in the fourth quarter to determine whether the fair value has decreased and additionally when events indicate an impairment may have occurred. Goodwill is all related to our drilling segment, and
accordingly, the impairment test is based on the estimated discounted future net cash flows of our drilling segment, utilizing discount rates and other factors in determining the fair value of our drilling segment. No goodwill impairment was
recorded at December 31, 2009, 2008 or 2007.

Turnkey and Footage Drilling
Contracts.Because our contract drilling operations do not bear the risk of completion of a well being drilled under a daywork contract, we recognize revenues and expense generated under daywork
contracts as the services are performed. Under footage and turnkey contracts we bear the risk of completion of the well, so revenues and expenses are recognized when the well is substantially completed. Substantial completion
is determined when the well bore reaches the depth specified in the contract. The entire amount of a loss, if any, is recorded when the loss can be reasonably determined, however, any profit is recorded only at the time the well is finished. The
costs of drilling contracts uncompleted at the end of the reporting period (which includes expenses incurred to date on footage or turnkey contracts) are included in other current assets. In 2009, we drilled one well under a
footage contract and in 2008, we did not drill any wells under turnkey or footage contracts.

Mid-Stream
Contracts.We recognize revenue from the gathering and processing of natural gas and NGLs in the period the service is provided based on contractual terms.

Accounting for Value of Stock Compensation Awards.To account for stock-based compensation, compensation cost
is measured at the grant date based on the fair value of an award and is recognized over the service period, which is usually the vesting period. We elected to use the modified prospective method, which requires compensation expense to be recorded
for all unvested stock options and other equity-based compensation beginning in the first quarter of adoption. The determination of the fair value of an award requires significant estimates and subjective judgments regarding, among other things, the
appropriate option pricing model, the expected life of the award and performance vesting criteria assumptions. As there are inherent uncertainties related to these factors and our judgment in applying them to the fair value determinations, there is
risk that the recorded stock compensation may not accurately reflect the amount ultimately earned by the employee.

Accounting for Derivative Instruments and Hedging.We account for derivative contracts to hedge against possible future interest rate increases and the variability in cash flows associated with the forecasted
sale of our future natural gas, NGLs and oil production. We have hedged a portion of our anticipated oil and natural gas production for the next 12months. This statement requires all derivatives to be recognized on the balance sheet and measured at
fair value. If a derivative is designated as a cash flow hedge, we are required to measure the effectiveness of the hedge, or the degree that the gain (loss) for the hedging instrument offsets the loss (gain) on the hedged item, at each reporting
period. The effective portion of the gain (loss) on the derivative instrument is recognized in other comprehensive income as a component of equity and subsequently reclassified into earnings

when the forecasted transaction affects earnings. The ineffective portion of a derivatives change in fair value is required to be recognized in earnings immediately. Derivatives that do not
qualify for hedge treatment must be recorded at fair value with gains (losses) recognized in earnings in the period of change.

New
Accounting Standards

The FASB Accounting Standards
Codification.FASB Accounting Standards Codification (ASC) became effective during the third quarter of 2009. ASC 105, Generally Accepted Accounting Principles, (guidance formerly reflected in FAS168) established
the ASC as the single source of authoritative U.S. generally accepted accounting principles (U.S. GAAP) recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the SEC under authority of federal
securities laws are also sources of authoritative U.S. GAAP for SEC registrants. The ASC supersedes all existing non-SEC accounting and reporting standards. All other nongrandfathered non-SEC accounting literature not included in the ASC will become
nonauthoritative. Following ASC 105, the FASB will not issue new standards in the form of Statements, FASB Staff Positions, or Emerging Issues Task Force Abstracts. Instead, the FASB will issue Accounting Standards Updates, which will serve only to:
(a) update the ASC; (b) provide background information about the guidance; and (c) provide the basis for conclusions on the change(s) in the ASC. The adoption of this standard has changed how we reference various elements of U.S. GAAP
in our financial statement disclosures, but has no impact on our financial position, results of operation or cash flows.

Fair Value Measurements and Disclosures.Beginning in 2008, we adopted the effective provisions of ASC 820 Fair-Value Measurements (formerly FAS 157.) ASC 820 defines fair value in applying GAAP,
establishes a framework for measuring fair value and expands disclosures about fair-value measurements. ASC 820 does not change existing guidance as to whether or not an instrument is carried at fair value.

In February 2008, the FASB delayed the effective date of ASC 820 for one year for certain nonfinancial assets and nonfinancial liabilities,
except those recognized or disclosed at fair value in the financial statements on a recurring basis. On January 1, 2009, we adopted, the delayed provisions of ASC 820 related to nonfinancial assets and nonfinancial liabilities that are not
required or permitted to be measured at fair value on a recurring basis. The adoption of the delayed provisions did not have a material impact on our financial statements.

Modernization of Oil and Gas Reporting.On December 31, 2008, the Securities and Exchange Commission
(SEC) adopted major revisions to its rules governing oil and gas company reporting requirements. These include provisions that permit the use of new technologies to determine proved reserves, and that allow companies to disclose their probable and
possible reserves to investors. The current rules limit disclosure to only proved reserves. The new rules also require companies to report the independence and qualifications of the auditor of the reserve estimates and file reports when a third
party is relied on to prepare reserves estimates. The new rules also require that oil and gas reserves be reported and the full cost ceiling value calculated using an average price based on the first-of-month posted price for each month in the prior
12-month period. On January 5, 2010, the FASB issued Accounting Standards update (ASU) 2010-03Extractive ActivitiesOil and Gas (ASC 932): Oil and Gas Reserve Estimation and Disclosures, an update of ASC 932 Extractive
ActivitiesOil and Gas, which subsequently aligns the reserve estimation, disclosure requirements, and definitions of ASC 932 with the disclosure requirements of the new rules issued by the SEC. The new oil and gas reserve measurement and
reporting requirements were adopted for oil and gas reserves as of December 31, 2009. For accounting purposes, the new requirements constitute a change in accounting principle inseparable from a change in estimate. As such, prior reserve
disclosures were not modified and the impact of the new requirements on our oil and gas reserves was reflected as a change in estimate. As previously noted, reserves and discounted cash flows prepared using the new rules were used in the calculation
of DD&A for the fourth quarter of 2009 and the ceiling test at December 31, 2009.

Interim Disclosures about Fair
Value of Financial Instruments.On June 30, 2009, we implemented certain provisions of ASC 825, Financial Instruments, (guidance formerly reflected in FASB Staff Position



47



---

##### Table of Contents

(FSP) Statement No. 107-1 and Accounting Principles Board (APB) 28-1, Interim Disclosures about Fair Value of Financial Instruments). The new provisions require disclosures about fair
value of financial instruments in interim financial information. We are required to disclose in the body or in the accompanying notes of our summarized financial information for interim reporting periods and in our financial statements for annual
reporting periods, the fair value of all financial instruments for which it is practicable to estimate that value, whether recognized or not recognized in the statement of financial position. We have included the required disclosure in Note 6 of our
Notes to Consolidated Financial Statements.

Subsequent Events.On June 30, 2009, we
implemented certain provisions of ASC 855, Subsequent Events, (guidance formerly reflected in FAS165, Subsequent Events).The new provision establishes general standards of accounting for and disclosure of events that occur
after the balance sheet date but before financial statements are issued or are available to be issued. ASC 855 provides:



| |  |  | The period after the balance sheet date during which management of a reporting entity should evaluate events or transactions that may occur for
potential recognition or disclosure in the financial statements;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The circumstances under which an entity should recognize events or transactions occurring after the balance sheet date in its financial statements; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The disclosures that an entity should make about events or transactions that occurred after the balance sheet date.
| | - |  | -------------------------------------------------------------------------------------------------------------------

We have included the required disclosure in Note 2 of our Notes to Consolidated Financial Statements.

Consolidations of Variable Interest Entities.On June 12, 2009, the FASB issued ASU
2009-17Consolidations (ASC 810): Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities, the FASB amended the authoritative guidance on consolidation which requires an enterprise to perform an
analysis to determine whether the enterprises variable interest or interests give it a controlling financial interest in a variable interest entity. In order to be the primary beneficiary of a variable interest entity, an enterprise must have
(a) the power to direct the activities of a variable interest entity that most significantly impact the entitys economic performance, and (b) the obligation to absorb losses of the entity that could potentially be significant to the
variable interest entity or the right to receive benefits from the entity that could potentially be significant to the variable interest entity. Along with these criteria, an enterprise is now required to assess whether it has an implicit financial
responsibility to ensure that a variable interest entity operates as designed when determining (a) above. Also, the enterprise is required to perform ongoing reassessments of whether an enterprise is the primary beneficiary of a variable
interest entity. The quantitative approach previously required for determining the primary beneficiary has been eliminated. Additional disclosures are now required in order to provide users of financial statements with more transparent information
about an enterprises involvement in a variable interest entity. This amendment is effective for the first fiscal year beginning after November 15, 2009. This ASU does not currently have a material impact on us.

Improving Disclosures about Fair Value Measurements.In January 2010, the FASB issued ASU 2010-06Fair
Value Measurements and Disclosures (ASC 820): Improving Disclosures about Fair Value Measurements, which provides additional guidance to improve disclosures regarding fair value measurements. The ASU amends ASC 820-10, Fair Value Measurements
and DisclosuresOverall (formerly FAS 157, Fair Value Measurements) to add two new disclosures: (1) transfers in and out of Level 1 and 2 measurements and the reasons for the transfers, and (2) a gross presentation of
activity within the Level 3 roll forward. The ASU also includes clarifications to existing disclosure requirements on the level of disaggregation and disclosures regarding inputs and valuation techniques. The ASU applies to all entities required to
make disclosures about recurring and nonrecurring fair value measurements. The effective date of the ASU is the first interim or annual reporting period beginning after December 15, 2009, except for the gross presentation of the Level 3 roll
forward information, which is required for annual reporting periods beginning after December 15, 2010 and for interim reporting periods within those years. This statement will not have a significant impact on us due to it only requiring
enhanced disclosures.

Financial Condition and Liquidity

Summary.    Our financial condition and liquidity depends on the cash flow from our operations and
borrowings under our Credit Facility. Our cash flow is influenced mainly by:



| |  |  | the demand for and the dayrates we receive for our drilling rigs;
| | - |  | -----------------------------------------------------------------



| |  |  | the quantity of natural gas, oil and NGLs we produce;
| | - |  | -----------------------------------------------------



| |  |  | the prices we receive for our natural gas production and, to a lesser extent, the prices we receive for our oil and NGL production; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the margins we obtain from our natural gas gathering and processing contracts.

##### Table of Contents

At December 31, 2009, we had unrestricted cash of $1.1 million and we had borrowed
$30.0 million of the $325.0 million available under our Credit Facility. Our Credit Facility is primarily used for working capital, capital expenditures and acquisitions. Prior to 2009, most of our capital expenditures are discretionary and directed
toward future growth. Beginning in the fourth quarter of 2008 and continuing through 2009, we significantly reduced our level of capital expenditures due to the uncertain economic environment. For 2010, we plan to increase our level of capital
expenditures, again being focused on growth and funded mainly through internally generated cash flow and to a lesser extent from borrowings under the credit facility.

Working Capital.Typically, our working capital balance fluctuates primarily because of the timing of our accounts receivable and accounts payable. We had working
capital of $22.9 million, $90.2 million and $40.6 million as of December 31, 2009, 2008 and 2007, respectively. The effect of our derivatives increased working capital by $4.7 million, $32.4 million and $1.3 million as of December 31,
2009, 2008 and 2007, respectively.

Contract Drilling.    Our contract drilling work is
subject to many factors that influence the number of drilling rigs we have working as well as the costs and revenues associated with that work. These factors include the demand for drilling rigs, competition from other drilling contractors, the
prevailing prices for natural gas and oil, availability and cost of labor to run our drilling rigs and our ability to supply the equipment needed.

If the current depressed conditions within our industry continue, we do not anticipate that competition to keep and attract qualified employees to meet our immediate and future requirements will
materially affect us. Likewise, if current commodity price and industry drilling utilization rates continue, we do not anticipate that our contract drilling labor costs will increase from those levels in effect at the end of the fourth quarter of
2009.

Most of our drilling rig fleet is used to drill natural gas wells so changes in natural gas prices have a
disproportionate influence on the demand for our drilling rigs as well as the prices we can charge for our contract drilling services. In 2009, our average dayrate was $16,713 per day compared to $18,458 per day in 2008 and $18,663 per day in 2007.
The average number of our drilling rigs used in 2009 was 38.9 drilling rigs (30%) compared with 103.1 drilling rigs (79%) in 2008 and 99.4 drilling rigs (80%) for 2007. Based on the average utilization of our drilling rigs during
2009, a $100 per day change in dayrates has a $3,890 per day ($1.4 million annualized) change in our pre-tax operating cash flow. Industry demand for our drilling rigs remained strong during the second and third quarters of 2008 before the fourth
quarter downturn. We expect that utilization and dayrates for our drilling rigs will slowly improve for 2010 compared to 2009 and depend mainly on the price of natural gas, the levels of natural gas storage and the availability of drilling rigs to
meet the demands of the industry.

Our contract drilling subsidiaries provide drilling services for our exploration and
production subsidiary. The contracts for these services contain the same terms and rates as the contracts we use with unrelated third parties for comparable type projects. During 2009, 2008 and 2007, we drilled 38, 122 and 77 wells, respectively,
for our exploration and production subsidiary. The profit associated with these wells received by our contract drilling segment of $1.3 million, $27.9 million and $22.7 million during 2009, 2008 and 2007, respectively, was used to reduce the
carrying value of our oil and natural gas properties rather than being included in our operating profit.

Impact of
Prices for Our Oil, NGLs and Natural Gas.    Natural gas comprises approximately 73% of our oil, NGLs and natural gas reserves. Any significant change in natural gas prices has a material effect on our revenues, cash flow
and the value of our oil, liquids and natural gas reserves. Generally, prices and demand for domestic natural gas are influenced by weather conditions, supply imbalances and by worldwide oil price levels. Domestic oil prices are primarily influenced
by world oil market developments. All of these factors are beyond our control and we cannot predict nor measure their future influence on the prices we will receive.

Based on our production in 2009, a $0.10 per Mcf change in what we are paid for our natural gas production, without the effect of hedging, would result in a corresponding $359,000 per month ($4.3 million

annualized) change in our pre-tax operating cash flow. Our 2009 average natural gas price was $5.59 compared to an average natural gas price of $7.62 for 2008 and $6.30 for 2007. A $1.00 per
barrel change in our oil price, without the effect of hedging, would have an $101,000 per month ($1.2 million annualized) change in our pre-tax operating cash flow and a $1.00 per barrel change in our NGL prices, without the effect of hedging, would
have a $123,000 per month ($1.5 million annualized) change in our pre-tax operating cash flow based on our production in 2009. Our 2009 average oil price per barrel was $56.33 compared with an average oil price of $93.87 in 2008 and $70.61 in 2007
and our 2009 average NGL price per barrel was $22.81 compared with an average liquids price of $47.42 in 2008 and $45.03 in 2007.

Because natural gas prices have such a significant effect on the value of our oil, NGLs and natural gas reserves, declines in those prices can result in a decline in the carrying value of our oil and natural gas properties. Price declines
can also adversely affect the semi-annual determination of the amount available for us to borrow under our bank credit facility since that determination is based mainly on the value of our oil, NGLs and natural gas reserves. Such a reduction could
limit our ability to carry out our planned capital projects.

Most of our natural gas production is sold to third parties
under month-to-month contracts.

Mid-Stream Operations.    Our mid-stream operations are
conducted through Superior Pipeline Company, L.L.C. and its subsidiary. Superior is a mid-stream company engaged primarily in the buying, selling, gathering, processing and treating of natural gas and operates three natural gas treatment plants,
eight processing plants, 33 gathering systems and 839 miles of pipeline. Superior operates in Oklahoma, Texas, Kansas and Pennsylvania and has been in business since 1996. This segment enhances our ability to gather and market not only our own
natural gas but also that owned by third parties and serves as a mechanism through which we can construct or acquire existing natural gas gathering and processing facilities. During 2009, 2008 and 2007 this segment purchased $29.3 million, $52.0
million and $18.4 million, respectively, of our natural gas production and natural gas liquids and provided gathering and transportation services of $4.6 million, $4.3 million and $4.7 million, respectively. Intercompany revenue from services and
purchases of production between this business segment and our oil and natural gas segment has been eliminated in our consolidated financial statements.

Our mid-stream segment gathered an average of 183,989 MMBtu per day in 2009 compared to 197,367 MMBtu per day in 2008 and 219,635 MMBtu per day in 2007, processed an average of 75,908 MMBtu per day in
2009 compared to 67,796 MMBtu per day in 2008 and 50,350 MMBtu per day in 2007 and sold NGLs of 243,492 gallons per day in 2009 compared to 195,837 gallons per day in 2008 and 129,421 gallons per day in 2007. The average gas gathering volumes per
day in 2009 decreased 7% compared to 2008 primarily due to a decline in our Southeast Oklahoma gathering system due to natural production declines associated with the connected wells and decreased new well connections. Volumes processed increased
due to the increase in NGL volumes sold.

Our Credit Facility.    On December 23, 2008,
we entered into a First Amendment to our existing First Amended and Restated Senior Credit Agreement (Credit Facility) with a maximum credit amount of $400.0 million maturing on May 24, 2012. This amendment increased the lenders
commitment by $50.0 million to an aggregate of $325.0 million. Borrowings under the Credit Facility are limited to a commitment amount elected by us. As of December 31, 2009, the commitment amount was $325.0 million. We are charged a commitment
fee of 0.375 to 0.50 of 1% on the amount available but not borrowed with the rate varying based on the amount borrowed as a percentage of the total borrowing base amount. We incurred origination, agency and syndication fees of $737,500 at the
inception of the Credit Facility and $478,125 associated with the December 23, 2008 First Amendment. These fees are being amortized over the life of the agreement. The average interest rate for 2009 was 4.0%. At both December 31, 2009 and
February 12, 2010, borrowings were $30.0 million.

The lenders aggregate commitment is limited to the lesser of the amount of the value of the borrowing
base or $400.0 million. The amount of the borrowing base, which is subject to redetermination on April 1 and October 1 of each year, is based primarily on a percentage of the discounted future value of our oil, NGLs and natural gas
reserves, as determined by the lenders, and, to a lesser extent, the loan value the lenders reasonably attribute to the cash flow (as defined in the Credit Facility) of our mid-stream operations. The current borrowing base is $475.0 million. We or
the lenders may request a onetime special redetermination of the borrowing base amount between each scheduled redetermination. In addition, we may request a redetermination following the consummation of an acquisition meeting the requirements
defined in the Credit Facility.

At our election, any part of the outstanding debt under the Credit Facility may be fixed at
LIBOR for a 30, 60, 90 or 180 day term. During any LIBOR funding period, the outstanding principal balance of the promissory note to which the LIBOR option applies may be repaid on three days prior notice to the administrative agent and on our
payment of any applicable funding indemnification amounts. Interest on the LIBOR is computed at the LIBOR base applicable for the interest period plus 1.75% to 2.50% depending on the level of debt as a percentage of the borrowing base and is payable
at the end of each term, or every 90 days, whichever is less. Borrowings not under the LIBOR bear interest at the BOKF National Prime Rate, which in no event will be less than LIBOR plus 1.00%, and is payable at the end of each month. Any amount
borrowed not subject to LIBOR may be repaid at any time, in part or in whole, without premium or penalty. At December 31, 2009, all of our outstanding borrowings of $30.0 million were subject to LIBOR.

The Credit Facility prohibits:



| |  |  | the payment of dividends (other than stock dividends) during any fiscal year in excess of 25% of our consolidated net income for the preceding fiscal
year;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the incurrence of additional debt with certain very limited exceptions; and
| | - |  | ---------------------------------------------------------------------------



| |  |  | the creation or existence of mortgages or liens, other than those in the ordinary course of business, on any of our properties, except in favor of our
lenders.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------

The Credit Facility also requires that we have at the end of each quarter:



| |  |  | a consolidated net worth of at least $900.0 million;
| | - |  | ----------------------------------------------------



| |  |  | a current ratio (as defined in the Credit Facility) of not less than 1 to 1; and
| | - |  | --------------------------------------------------------------------------------



| |  |  | a leverage ratio of long-term debt to consolidated EBITDA (as defined in the Credit Facility) for the most recently ended rolling four fiscal quarters
of no greater than 3.50 to 1.0.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As of December 31, 2009, we were in compliance with the covenants
contained in the Credit Facility.

Capital Requirements

Drilling Acquisitions and Capital Expenditures.    During 2006, we purchased major
components to be used in the construction of two new 1,500 horsepower drilling rigs. The first was placed into service in our Rocky Mountain division at the end of March 2007 and the second was placed into service in the second quarter of 2007. The
combined capitalized cost of both drilling rigs was $19.4 million. On June 5, 2007, we completed the acquisition of a privately owned drilling company operating primarily in the Texas Panhandle. The acquired company owned nine drilling rigs, a
fleet of 11 trucks, and an office, shop and equipment yard. The drilling rigs range from 800 horsepower to 1,000 horsepower with depth capacities rated from 10,000 to 15,000 feet. Eight of the nine drilling rigs were operating under contracts on the
acquisition date. The remaining drilling rig was refurbished and placed in service during the first quarter of 2008. Results of operations for the acquired company have been included in our statements of income beginning June 5, 2007. Total
consideration paid for this acquisition was $38.5 million.

For our contract drilling operations, during 2007, we recorded
$220.4 million in capital expenditures including the effect of a $19.4 million deferred tax liability and $5.3 million in goodwill associated with our second quarter 2007 acquisition.

For 2008, our capital expenditures for this segment were $196.2 million. During the second quarter of 2008, we completed the construction of
two new 1,500 horsepower diesel electric drilling rigs for approximately $32.2 million and placed these drilling rigs into service in our Rocky Mountain division. During the fourth quarter of 2008, we completed the construction of another new 1,500
horsepower diesel electric drilling rig for approximately $14.1 million and placed that drilling rig into service in North Dakota.

In late 2008, we postponed the construction of eight additional drilling rigs we had previously anticipated building. In the third quarter 2009, we recognized an early termination fee associated with the cancellation of long-term contracts
by a customer on two of these eight rigs. In addition, as a result of an existing contractual obligation, we took delivery of a new 1,500 horsepower drilling rig during the fourth quarter of 2009 at a cost of $13.2 million. The customer who had
signed a two year term contract for this rig when it was ordered, opted not to take delivery of the rig and paid an early termination fee under the contract provisions during the fourth quarter of 2009.

We agreed to delay the delivery of a new 1,500 horsepower diesel electric drilling rig that was to have been delivered to North Dakota under
a long term contract in the first quarter of 2009. Under that agreement, our customer agreed to make monthly payments pending the future delivery of the rig. Our customer has now advised us to prepare the rig for mobilization to North Dakota
for use in their drilling program during the first quarter of 2010.

We currently do not have a shortage of drill pipe and
drilling equipment. At December 31, 2009, we had commitments to purchase approximately $0.8 million of drilling rig components and $18.0 million of drill pipe and drill collars in 2010. For 2009, our capital expenditures were $67.7 million. Our
anticipated 2010 capital expenditures for this segment are $76.0 million.

In January and February 2010, our contract drilling segment entered into contracts to sell
eight of its idle mechanical drilling rigs to an unaffiliated third party. These drilling rigs ranged in horse power from 800 to 1,000. The closing on three of these drilling rigs occurred in February. Three more are scheduled to close
during the first quarter of 2010 with the last transaction for the remaining two rigs anticipated to close during the second quarter of 2010. Proceeds from the sale of all the drilling rigs will be $23.9 million resulting in an estimated gain of
$6.1 million. The proceeds from this sale will be used to refurbish and upgrade additional rigs in our fleet in order that those rigs can be used in horizontal drilling operations. We also placed into service in our Rocky Mountain division a 1,500
horsepower, diesel-electric drilling rig that previously had been placed on hold during 2009 by our customer. At completion of the sale of the eight rigs and with the additional rig recently placed into service, this segment will have 123 drilling
rigs in its fleet.

Oil and Natural Gas Acquisitions and Capital Expenditures.    Most of
our capital expenditures for this segment are discretionary and directed toward future growth. Our decision to increase our oil, NGLs and natural gas reserves through acquisitions or through drilling depends on the prevailing or expected market
conditions, potential return on investment, future drilling potential and opportunities to obtain financing under the circumstances involved, all of which provide us with a large degree of flexibility in deciding when and if to incur these costs. We
completed drilling 95 gross wells (42.51 net wells) in 2009 compared to 278 gross wells (134.31 net wells) in 2008 and 253 gross wells (96.64 net wells) in 2007. Our 2009 total capital expenditures for our oil and natural gas segment, excluding a
$4.6 million ARO liability, totaled $226.0 million. Currently we plan to participate in drilling approximately 175 gross wells in 2010 and estimate our total capital expenditures (excluding any possible acquisitions) for our oil and natural gas
segment will be approximately $365.0 million. Whether we are able to drill the full number of wells we are planning on drilling is dependent on a number of factors, many of which are beyond our control and include the availability of drilling rigs,
prices for oil, NGLs and natural gas, demand for oil and natural gas, the cost to drill wells, the weather and the efforts of outside industry partners.

On January 18, 2008, we purchased a 50% interest in a 6,800 gross-acre leasehold that we did not already own in our Segno area of operations located in Hardin County, Texas. Included in the purchase
were five producing wells with 4.9 Bcfe of estimated proved reserves and current production of 2.8 MMcf of natural gas per day and 88.2 barrels of condensate. The purchase price was $16.8 million which consisted of $15.8 million allocated to the
reserves of the wells and $1.0 million allocated to the undeveloped leasehold.

In September 2008, we completed an acquisition
consisting of a 75% working interest in four producing wells and other proved undeveloped properties for $22.2 million along with working interests in undeveloped leasehold valued at approximately $3.5 million, all located in the Texas Panhandle
region.

During 2008 and 2009, we acquired interests in approximately 60,000 net undeveloped acres in the Marcellus Shale
Play, located mainly in Pennsylvania and Maryland for approximately $43.6 million. In July 2009, we received $7.1 million and approximately 1,500 net undeveloped acres, representing payment for our 50% interest in 4,000 gross undeveloped acres and
reimbursement for costs we paid on their behalf. On September 30, 2009, per our agreement with certain unaffiliated third parties, we were paid approximately $14.9 million for our 50% interest in approximately 18,000 gross undeveloped
acres of the Marcellus Shale and $26.1 million for a receivable from the third parties for their 50% share of the costs we paid on their behalf to acquire the acreage. The sales proceeds reduced undeveloped leasehold and no gain or loss was recorded
on this sale. We now have an interest in approximately 50,500 net undeveloped acres.

As of December 31, 2009, we had
commitments to purchase casing for $0.5 million.

Mid-Stream Acquisitions and Capital
Expenditures.    As of December 31, 2008, we had commitments to purchase two new processing plants. After December 31, 2008, we cancelled the purchase of one of these plants due to nonperformance of contractual
terms. We are seeking to recover the $2.8 million progress payments made toward the full purchase price before this contract was terminated. In March 2009, we cancelled our remaining commitment for the second plant and incurred a $1.3 million
penalty.

##### Table of Contents

During 2009, our mid-stream segment incurred $9.9 million in capital expenditures as
compared to $49.9 million in 2008 and $34.2 million in 2007, including acquisitions. For 2010, we have budgeted capital expenditures of approximately $53.0 million. The increase over 2009 expenditures is due to anticipated drilling activity by
operators in the areas of our existing gathering systems resulting in new well connections as well as adding an additional processing facility to accommodate the increased drilling activity of our oil and natural gas segment.

Contractual Commitments.    At December 31, 2009, we had the following contractual obligations:

After December 31, 2009, we amended the lease for our office space in Tulsa,
Oklahoma. Subject to all the terms of the lease, the amendment extended the lease from January 2010 to January 2015 for an approximate commitment of $6.0 million. Also, subsequent to December 31, 2009, we entered into an agreement to purchase a
50mmcf/d gas plant for approximately $6.2 million which is to be paid in 2010.

At December 31, 2009, we also had the

|(2) | Effective January 1, 1997, we adopted a separation benefit plan (Separation Plan). The Separation Plan allows eligible employees whose employment with
us is involuntarily terminated or, in the case of an employee who has completed 20 years of service, voluntarily or involuntarily terminated, to receive benefits equivalent to four weeks salary for every whole year of service completed with the
company up to a maximum of 104 weeks. To receive payments the recipient must waive any claims against us in exchange for receiving the separation benefits. On October 28, 1997, we adopted a Separation Benefit Plan for Senior Management
(Senior Plan). The Senior Plan provides certain officers and key executives of the company with benefits generally equivalent to the Separation Plan. The Compensation Committee of the Board of Directors has absolute discretion in the
selection of the individuals covered in this plan. On May 5, 2004 we also adopted the Special Separation Benefit Plan (Special Plan). This plan is identical to the Separation Benefit Plan with the exception that the benefits under
the plan vest on the earliest of a participants reaching the age of 65 or serving 20 years with the company. On December 31, 2008, all these plans were amended to bring the plans into compliance with Section 409A of the Internal
Revenue Code of 1986, as amended.

|(3) | When a well is drilled or acquired we have recorded the fair value of liabilities associated with the retirement of long-lived assets (mainly plugging and abandonment
costs for our depleted wells).
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(4) | We have recorded a liability for those properties we believe do not have sufficient oil, NGLs and natural gas reserves to allow the under-produced owners to recover
their under-production from future production volumes.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(5) | We formed The Unit 1984 Oil and Gas Limited Partnership and the 1986 Energy Income Limited Partnership along with private limited partnerships (the Partnerships) with
certain qualified employees, officers and directors from 1984 through 2010, with a subsidiary of ours serving as general partner. The Partnerships were formed for the purpose of conducting oil and natural gas acquisition, drilling and development
operations and serving as co-general partner with us in any additional limited partnerships formed during that year. The Partnerships participated on a proportionate basis with us in most drilling operations and most producing property acquisitions
commenced by us for our own account during the period from the formation of the Partnership through December 31 of that year. These partnership agreements require, on the election of a limited partner, that we repurchase the limited
partners interest at amounts to be determined by appraisal in the future. Such repurchases in any one year are limited to 20% of the units outstanding. We made repurchases of $1,000 and $241,000 in 2009 and 2008, respectively, and did not have
any repurchases in 2007.

Derivative Activities.    As of January 1, 2009, we applied the
provisions of ASC 815, Derivatives and Hedging,(guidance formerly reflected in FAS161, Disclosures about Derivative Instruments and Hedging Activities). The new provision requires enhanced disclosures about a companys derivative
activities and how the related hedged items affect a companys financial position, financial performance and cash flows. These enhanced disclosures are discussed in Note 13 of our Notes to Consolidated Financial Statements.

Periodically we enter into hedge transactions covering part of the interest we incur under our Credit Facility as well as the prices to be
received for a portion of our future oil, NGLs and natural gas production.

Interest Rate Swaps.From time to time we have entered into
interest rate swaps to help manage our exposure to possible future interest rate increases under our Credit Facility. As of December 31, 2009, we had two outstanding interest rate swaps which were cash flow hedges. Under these transactions we
have swapped the variable interest rate we would otherwise incur on a portion of our bank debt for a fixed interest rate. There was no material amount of ineffectiveness. Our December 31, 2009 balance sheet recognized the fair value of these
swaps as current and non-current derivative liabilities and is presented in the table below:



|                         |  |                  |        |           |      |   |               |               |                           |   |        |

|                         |  |                  |        |           |      |   |               |               |                           | $ | (1,948 | )
|                         |  |                  |        |           |      |   |               |               |                           |   |        |  

Because of these interest rate swaps, interest expense increased by $1.0 million and $0.3 million in 2009
and 2008, respectively. A loss of $1.2 million, net of tax, is reflected in accumulated other comprehensive income (loss) as of December 31, 2009.

Commodity Derivatives.    We use hedging to reduce price volatility and manage price risks. Our decision on the quantity and price at which we choose to hedge certain of our
production is based, in part, on our view of current and future market conditions. Based on our 2009 average daily production, as of February 12, 2010, the approximated percentages we have hedged are as follows:

Oil and Natural Gas Segment:



|                             |  |                       |   |  |                           |  
|---------------------------- |  | --------------------- | - |  | ------------------------- | -
|                             |  | January December2010 |   |  | January December2011 (1) |  
|Daily oil production         |  | 71                    | % |  |                          | %
|Daily natural gas production |  | 69                    | % |  |                          | %



|(1) | Currently for 2011, we only have basis differential swaps covering 30,000 MMBtu/day.
|--- | ------------------------------------------------------------------------------------

With respect to the commodities subject to the hedge, the use of hedging limits the risk of adverse downward price movements, but it also
limits increases in future revenues that would otherwise result from favorable price movements.

The use of derivative
transactions also involves the risk that the counterparties will be unable to meet the financial terms of the transactions. We considered this non-performance risk with regard to our counterparties and our own non-performance risk in our valuation
at December 31, 2009 and determined it was immaterial at that time. At February 12, 2010, Bank of Montreal, Bank of America, N.A., Calyon New York Branch, Comerica Bank and Compass Bank were the counterparties with respect to all of our
commodity derivative transactions. At December 31, 2009, the fair values of the net assets (liabilities) we had with each of these counterparties was $1.5 million, $6.3 million, $1.0 million, $1.1 million and ($1.4) million, respectively.

To the extent that a legal right of set-off exists, we net the value of our derivative arrangements with the same
counterparty in the accompanying consolidated balance sheets. At December 31, 2009, we recorded the fair value of our commodity derivatives on our balance sheet as current derivative assets of $9.9 million and current derivative liabilities of
$1.4 million. At December 31, 2008, we recorded the fair value of our commodity derivatives on our balance sheet as current and non-current derivative assets of $52.1 million and $5.2 million, respectively, and current derivative liabilities of
$0.7 million.

We recognize the effective portion of changes in fair value as accumulated other
comprehensive income (loss), and reclassify the recognized gains (losses) on the sales to revenue and the purchases to expense as the underlying transactions are settled. As of December 31, 2009, we had a gain of $5.7 million, net of tax from
our oil and natural gas segment derivatives and no gain or loss from our mid-stream segment derivatives in accumulated other comprehensive income (loss).

Based on market prices at December 31, 2009, we expect to transfer approximately $4.7 million, net of tax, of the $5.7 million, net of tax, gain included in the balance in accumulated other
comprehensive income (loss) to earnings during the next 12 months in the related month of production. The interest rate swaps and commodity derivative instruments as of December 31, 2009 are expected to mature by May 2012 and December 31,
2010, respectively.

Certain derivatives do not qualify for designation as cash flow hedges. We had two basis swaps that did
not qualify as cash flow hedges that expired in December 2009. Changes in the fair value of these non-qualifying derivatives that occur prior to their maturity (i.e., temporary fluctuations in value) are reported currently in the consolidated
statements of income as unrealized gains (losses) within oil and natural gas revenues. 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 into earnings. Any change in fair value resulting from ineffectiveness is recognized currently in oil and natural gas revenues as unrealized gains (losses).
The effect of these realized and unrealized gains and losses on our revenues and expenses were as follows at December 31:

Stock and Incentive Compensation.During 2009, we did not grant
any awards of restricted stock. During 2008, we granted awards covering 30,855 shares of restricted stock. These awards were granted as retention incentive awards. During 2007, we granted awards covering 616,907 shares of restricted stock. These
awards included specific one time retention awards as well as awards which were part of our annual compensation determinations. Also in 2007, we granted awards covering 101,236 shares of stock appreciation rights to certain of our executive
officers. No SAR awards were made during 2008 or 2009. During 2009, we recognized compensation expense of $9.2 million for all of our restricted stock, stock options and SAR grants and capitalized $2.1 million of compensation cost for oil and
natural gas properties. Compensation expense for the 2007 and 2008 grants has been recognized over the three year vesting periods.

Insurance.    We are self-insured for certain losses relating to workers compensation, control of well and employee medical benefits. Insured policies for other coverage contain
deductibles or retentions per occurrence that range from $50,000 for fiduciary liability to $1.0 million for drilling rig physical damage. We have purchased stop-loss coverage in order to limit, to the extent feasible, per occurrence and
aggregate exposure to certain types of claims. However, there is no assurance that the insurance coverage will adequately protect us against liability from all potential consequences. We have elected to use an ERISA governed occupational
injury benefit plan to cover all Texas drilling operations in lieu of covering them under Texas Workers

Compensation. If insurance coverage becomes more expensive, we may choose to self-insure, decrease our limits, raise our deductibles or any combination of these rather than pay higher
premiums.

Oil and Natural Gas Limited Partnerships and Other Entity Relationships.    We
are the general partner of 15 oil and natural gas partnerships which were formed privately or publicly. Each partnerships revenues and costs are shared under formulas set out in that partnerships agreement. The partnerships repay us for
contract drilling, well supervision and general and administrative expense. Related party transactions for contract drilling and well supervision fees are the related partys share of such costs. These costs are billed on the same basis as
billings to unrelated third parties for similar services. General and administrative reimbursements consist of direct general and administrative expense incurred on the related partys behalf as well as indirect expenses assigned to the related
parties. Allocations are based on the related partys level of activity and are considered by us to be reasonable. During 2009, 2008 and 2007, the total we received for all of these fees was $1.1 million, $1.9 million and $1.6 million,
respectively. We expect that these fees for 2010 will be comparable to those in 2009. Our proportionate share of assets, liabilities and net income relating to the oil and natural gas partnerships is included in our consolidated financial
statements.

Effects of Inflation

The effect of inflation in the oil and natural gas industry is primarily driven by the prices for oil and natural gas. Increases in these prices increase the demand for our contract drilling rigs and
services. This increase in demand in turn affects the dayrates we can obtain for our contract drilling services. Before 1999, the effect of inflation on our operations was minimal due to low inflation rates, relatively low natural gas and oil prices
and moderate demand for our contract drilling services. Over the last several years natural gas and oil prices have been more volatile, and during periods of higher demand for our drilling rigs we have experienced increases in labor costs as well as
the costs of services to support our drilling rigs. Historically, during this same period, when oil, NGLs and natural gas prices did decline, labor rates did not come back down to the levels existing before the increases. If natural gas prices
increase substantially for a long period, shortages in support equipment (such as drill pipe, third party services and qualified labor) will result in additional increases in our material and labor costs. Increases in dayrates for drilling rigs also
increase the cost of our oil and natural gas properties. How inflation will affect us in the future will depend on additional increases, if any, realized in our drilling rig rates, the prices we receive for our oil, NGLs and natural gas and the
rates we receive for gathering and processing natural gas.

Off-Balance Sheet Arrangements

We do not currently utilize any off-balance sheet arrangements with unconsolidated entities to enhance liquidity and capital resource
positions, or for any other purpose. However, as is customary in the oil and gas industry, we are subject to various contractual commitments.

Contract Drilling:

Drilling revenues decreased $386.4 million or 62% in 2009 versus 2008 primarily due to a 62% decrease in the average
number of rigs in use during 2009 compared to 2008. The decline in revenue was partially offset by $6.1 million of revenue recognized during the third and fourth quarters of 2009 from settlements of terminated drilling contracts. Average drilling
rig utilization decreased from 103.1 drilling rigs in 2008 to 38.9 drilling rigs in 2009. Our average dayrate in 2009 was 9% lower than in 2008. In the third and fourth quarters of 2008, prices for oil and natural gas decreased substantially and
natural gas prices continued to be at low levels during 2009 and may remain volatile for an indeterminable period of time. Entering the third quarter of 2009, the decline in utilization started to moderate and improved slightly through the end of
2009, but weak natural gas prices could

impact the demand for drilling rigs which may keep utilization rates at low levels. However, with anticipated increases to 2010 drilling activity and spending, we may see an increase on our 2010
drilling rig utilization as compared to levels at the end of 2009.

Drilling operating costs decreased $172.8 million or 55%
between the comparative years of 2009 and 2008 primarily due to the decrease in the number of drilling rigs used. The utilization decreases experienced in the industry since the third quarter of 2008 has reduced the demand for rig personnel which
has reduced the pressure on our labor costs. Likewise, that pressure on our other daily direct drilling costs resulted in little change of those costs as well, but reduced utilization has resulted in fewer rigs to cover our indirect fixed costs. As
demand for our rigs begins to increase so will the competition for qualified labor. Contract drilling depreciation decreased $24.5 million or 35%, we utilize the units of production method for the depreciation of our drilling rigs, therefore in
periods of reduced utilization a decrease in depreciation occurs.

Oil and Natural Gas:

Oil and natural gas revenues decreased $196.1 million or 35% in 2009 as compared to 2008 primarily due to a decrease in average oil, NGL and
natural gas prices. Average oil prices between the comparative years decreased 40% to $56.33 per barrel, NGL prices decreased 52% to $22.81 per barrel and natural gas prices decreased 27% to $5.59 per Mcf. In 2009, as compared to 2008, oil
production increased 2%, NGL production increased 7% and natural gas production decreased 7%. During 2009 approximately 1.2 Bcf of natural gas production was curtailed due to low commodity prices and the shut-in of third party plants. A large part
of our increase in revenues during 2008 was determined by the prices we received for our production. Commodity prices decreased substantially during the third and fourth quarters of 2008 and natural gas prices stayed at low levels during 2009 and
may remain volatile for an indeterminable period of time. As a result of these lower commodity prices as well as service costs that remained relatively high, we slowed our drilling activity during the fourth quarter of 2008 and continued to do so
through the second quarter of 2009. We began increasing activity during the third quarter of 2009 and currently plan to continue to increase our activity throughout 2010.

Oil and natural gas operating costs decreased $28.5 million or 25% between the comparative years of 2009 and 2008 primarily due to reduced production taxes associated with the large decrease in commodity
prices and $5.1 million in production tax credits attributable to high-cost gas wells. Also contributing to the decrease was a reduction in general and administrative expenses as compensation costs were reduced in response to the downturn in the
industry.

Total depreciation, depletion and amortization (DD&A), excluding ceiling test impairments, decreased $44.9
million or 28% primarily due to a 25% decrease in our DD&A and lower production volumes. The decrease in our DD&A rate in 2009 compared to 2008 resulted primarily from the $282.0 million and $281.2 million pre-tax non-cash ceiling test
write-down of the carrying value of our oil and natural gas properties in the fourth quarter of 2008 and the first quarter 2009, respectively, as a result of a decline in commodity prices. Our DD&A expense on our oil and natural gas properties
is calculated each quarter utilizing period end reserve quantities. The new SEC oil and gas reserves measurement and disclosure rules that went into effect as of December 31, 2009 impacted our DD&A expense for the fourth quarter of 2009,
increasing DD&A expense by $1.2 million (or $0.02 per share) for the quarter and year ended December 31, 2009.

Mid-Stream:

Our mid-stream revenues were $73.1 million or 40% lower for 2009 as compared to 2008 primarily due to lower NGL and
natural gas prices slightly offset by higher NGL volumes processed and sold. The average price for NGLs sold decreased 45% and the average price for natural gas sold decreased 55%. Gas processing volumes per day increased 12% between the comparative
periods and NGLs sold per day increased 24% between the comparative periods. The increase in volumes processed per day is primarily attributable to the volumes added from new wells connected to existing systems throughout 2008 and 2009. NGLs sold
volumes per day increased

due to both an increase in volumes processed and upgrades to several of our processing facilities. Gas gathering volumes per day decreased 7% primarily from well production declines associated
with the wells gathered from one of our gathering systems located in Southeast Oklahoma. NGL sales increased by $2.0 million in 2008 due to the impact of NGL hedges. There were no NGL hedges in place for 2009.

Operating costs decreased $62.6 million or 42% in 2009 compared to 2008 primarily due to a 52% decrease in prices paid for natural gas
purchased and an 8% decrease in field operating expense. Depreciation and amortization increased $1.3 million, or 9%, primarily attributable to the additional depreciation associated with capital expenditures between the comparative periods.
Operating costs increased by $1.4 million in 2008 due to the impact of natural gas purchase hedges; however there were no hedges in place during 2009. For 2010, we anticipate an increase in well connections over 2009 due to anticipated drilling
activity by operators in the areas of our existing gathering systems as well as adding an additional processing facility to accommodate the increased drilling activity of our oil and natural gas segment.

Other:

Other
revenue of $7.1 million for the year ended 2009 was primarily attributable to the sale of three mechanical drilling rigs during the year.

General and administrative expense decreased $1.4 million or 6% in 2009 compared to 2008. This decrease was primarily attributable to decreased payroll expenses due to efforts to manage cost in this
economic environment.

Interest expense, net of capitalized interest, decreased $0.8 million or 59% between the comparative
periods of 2009 and 2008. Capitalized interest reduced our interest expense by $5.1 million in 2009 versus $6.0 million in 2008. We capitalized interest based on the net book value associated with our undeveloped oil and natural gas properties, the
construction of additional drilling rigs and the construction of gas gathering systems. Our average interest rate was 11% lower and our average debt outstanding was 25% lower in 2009 as compared to 2008. Interest expense was increased $1.0 million
for 2009 and $0.3 million for 2008 from interest rate swap settlements.

Income tax expense (benefit) changed from an expense
of $82.0 million in 2008 to a benefit of $32.2 million in 2009 due to declines in income from lower commodity prices and reduced rig utilization and dayrates. Our effective tax rate was 36.7% and 37.0% for 2009 and 2008, respectively with the effect
of the deferred tax benefit related to the ceiling test write-down of our oil and natural gas properties. The portion of our taxes reflected as a current income tax benefit for 2009 was $0.2 million or 0.7% of the total income tax benefit for 2009
as compared with $40.9 million or 50% of total income tax expense in 2008. The decrease in the percentage of tax expense (benefit) and the reduction in tax expense recognized as current were both the result of lower taxable income. Income taxes paid
in 2009 were $12.3 million.

Contract Drilling:

Drilling revenues decreased $4.9 million or 1% in 2008 versus 2007 primarily due to our average dayrate in 2008
decreasing by 1% compared to 2007. Although the average number of drilling rigs operating in 2008 increased over 2007, the significant decline in prices for oil and natural gas beginning in the third quarter of 2008 and continuing throughout the
fourth quarter of 2008 resulted in a significant decrease in our utilization. The average number of drilling rigs operating during the third quarter of 2008 was 110.7, however by December of 2008, the average number of drilling rigs operating had
declined to 81.0.

Drilling operating costs increased $8.1 million or 3% between the comparative years of 2008 and 2007
primarily due to the increase in the number of drilling rigs used. Our labor costs increased late in the third quarter

of 2008, due to adjustments to rig crew personnel compensation. Contract drilling depreciation increased $13.0 million or 23% as the total number of drilling rigs owned increased between the
comparative periods.

Oil and Natural Gas:

Oil and natural gas revenues increased $162.5 million or 42% in 2008 as compared to 2007 due to an increase in average oil, NGL and natural gas prices and a 16% increase in equivalent production volumes.
Average oil prices between the comparative years increased 33% to $93.87 per barrel, NGL prices increased 5% to $47.42 per barrel and natural gas prices increased 21% to $7.62 per Mcf. In 2008, as compared to 2007, oil production increased 16%, NGL
production increased 77% and natural gas production increased 9%. Increased production came primarily from our ongoing internal development drilling activity. A large part of our increase in revenues during 2008 was determined by the prices we
received for our production. Commodity prices started to decrease during the third quarter of 2008 and continued to decrease throughout the fourth quarter of 2008. As a result of lower commodity prices combined with service costs that remain
relatively high, we slowed down our drilling activity during the fourth quarter of 2008.

Oil and natural gas operating costs
increased $19.1 million or 20% between the comparative years of 2008 and 2007. An increase in the average cost per equivalent Mcf produced represented 15% of the increase in operating costs with the remaining 85% of the increase attributable to the
increase in volumes produced from wells added from our developmental drilling. Increases in general and administrative expenses directly related to oil and natural gas production and gross production taxes from higher revenues contributed to the
majority of the operating cost increase. General and administrative expenses increased as labor costs increased primarily due to a 22% increase in the average number of employees working in the exploration and production area while lease operating
expenses increased primarily due to an increase in the number of wells producing and also from increases in the cost of goods purchased and third-party services. Gross production taxes increased primarily as a result of the increase in oil and
natural gas revenues.

DD&A increased $32.1 million or 25%. Higher production volumes accounted for 64% of the increase
while increases in our DD&A rate represented 36% of the increase. The increase in our DD&A rate in 2008 compared to 2007 resulted primarily from increases in the cost of oil and natural gas reserves added in 2007 and 2008 due to higher
drilling and completion costs.

We recorded a non-cash ceiling test write down of $282.0 million pre-tax ($175.5 million, net
of tax) during the year ended December 31, 2008 as a result of declines in commodity prices. After December 31, 2008 commodity prices have continued to decrease.

Mid-Stream:

Our mid-stream revenues were $43.1 million or 31%
higher for 2008 as compared to 2007 due to the higher NGL volumes processed and sold combined with higher NGL and natural gas prices. The average price for NGLs sold increased 15% and the average price for natural gas sold increased 17%. Gas
processing volumes per day increased 35% between the comparative years and NGLs sold per day increased 51% between the comparative years. A 10% decrease in gathering volumes per day partially offset the increase in revenue from natural gas liquids
and processing sales. The significant increase in volumes processed per day is primarily attributable to the installation of three processing plants in 2007 and, to a lesser extent, volumes added from new wells connected to existing systems
throughout 2007 and 2008. NGLs sold volumes per day increased due to recent upgrades to several of our processing facilities. Gas gathering volumes decreased primarily from well production declines associated with the wells gathered from one of our
gathering systems located in Southeast Oklahoma. NGL sales increased by $2.0 million in 2008 compared to being reduced by $2.1 million in 2007 due to the impact of NGL hedges.

Operating costs increased $30.7 million or 26% in 2008 compared to 2007 due to a 25% increase in natural gas volumes purchased per day and a
18% increase in prices paid for natural gas purchased, a 25% increase in

##### Table of Contents

field direct operating expense due to the additions to our natural gas gathering and processing systems and the volume of natural gas processed and an 72% increase in general and administrative
expenses associated with our mid-stream segment. The total number of employees working in our mid-stream segment increased by 44%. Depreciation and amortization increased $3.8 million, or 34%, primarily attributable to the additional depreciation
associated with assets acquired between the comparative periods. Operating costs increased by $1.4 million in 2008 compared to $1.7 million in 2007 due to the impact of natural gas purchase hedges. Commodity prices started to decline in the third
quarter of 2008 and continued to decrease throughout the fourth quarter of 2008.

Other:

General and administrative expense increased $3.4 million or 15% in 2008 compared to 2007. This increase was primarily attributable to
increased stock based compensation costs and increased payroll expenses due to an 8% increase in the number of employees.

Total interest expense, net of capitalized interest, decreased $5.1 million or 80% between the comparative years. Our average debt outstanding and our average interest rate were 12% and 25% lower, respectively, in 2008 as compared to 2007.
We capitalized interest based on the net book value associated with our undeveloped inventory of oil and natural gas properties, the construction of additional drilling rigs and the construction of gas gathering systems. Capitalized interest reduced
our interest expense by an additional $1.5 million in 2008 versus 2007 and represented 29% of the $5.1 million decrease in interest expense. Interest expense was increased $0.3 million for 2008 and was reduced $0.7 million for 2007 from interest
rate swap settlements.

Income tax expense decreased $65.2 million or 44% due primarily to the decrease in income before
income taxes associated with the write down of our oil and natural gas properties creating an income tax benefit of $106.4 million. Our effective tax rate was 37% and 36% for 2008 and 2007, respectively before the effect of the deferred tax benefit
related to the ceiling test write-down of our oil and natural gas properties. The portion of our taxes reflected as current income tax expense for 2008 was $40.9 million or 50% of total income tax expense for 2008 as compared with $66.6 million or
45% of total income tax expense in 2007. The increase in the percentage of tax expense recognized as current is the result of the deferred income tax benefit recognized in 2008 in association with the write down of our oil and natural gas
properties. Income taxes paid in 2008 were $45.7 million.



|Item 7A. | Quantitative and Qualitative Disclosures about Market Risk
|-------- | ----------------------------------------------------------

Our operations are exposed to market risks primarily as a result of changes in the prices for natural gas and oil and interest rates.

Commodity Price Risk.    Our major market risk exposure is in the prices we receive for our
oil, NGLs and natural gas production. Those prices are primarily driven by the prevailing worldwide price for crude oil and market prices applicable to our natural gas production. Historically, these prices have fluctuated and we expect they will
continue to do so. The price of oil, NGLs and natural gas also affects both the demand for our drilling rigs and the amount we can charge for the use of our drilling rigs. Based on our 2009 production, a $0.10 per Mcf change in what we are paid for
our natural gas production would result in a corresponding $359,000 per month ($4.3 million annualized) change in our pre-tax cash flow. A $1.00 per barrel change in our oil price would have an $101,000 per month ($1.2 million annualized) change in
our pre-tax operating cash flow and a $1.00 per barrel change in our NGLs prices would have a $123,000 per month ($1.5 million annualized) change in our pre-tax cash flow.

We use hedging transactions to reduce price volatility and manage price risks. Our decisions regarding the amount and prices at which we
choose to hedge certain of our products is based, in part, on our view of current

and future market conditions. The transactions we use include financial price swaps under which we will receive a fixed price for our production and pay a variable market price to the contract
counterparty, and collars that set a floor and ceiling price for the hedged production. If the applicable monthly price indices are outside of the ranges set by the floor and ceiling prices in the various collars, we will settle the difference with
the counterparty to the collars. Currently, we also have one basis swap that does not qualify as cash flow hedge. These financial derivatives are intended to support oil and gas prices at targeted levels and to manage our exposure to oil and gas
price fluctuations. We do not hold or issue derivative instruments for speculative trading purposes.

Interest Rate
Risk.    Our interest rate exposure relates to our long-term debt under our Credit Facility. That debt, at our election bears interest at variable rates based on the BOKF National Prime Rate or the LIBOR Rate. At our
election, borrowings under our Credit Facility may be fixed at the LIBOR Rate for periods of up to 180 days. To help manage our exposure to any future interest rate volatility, we currently have two $15.0 million interest rate swaps, one at a fixed
rate of 4.53% and one at a fixed rate of 4.16%, both expiring in May 2012. Under these transactions we have swapped the variable interest rate we would otherwise incur on a portion of our bank debt for a fixed interest rate. Based on our average
outstanding long-term debt subject to a variable rate in 2009, a 1% increase in the floating rate would reduce our annual pre-tax cash flow by approximately $0.8 million.

Managements Report on Internal Control over Financial
Reporting

Management of the company is responsible for establishing and maintaining adequate internal control over
financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) or 15d-15(f) promulgated under the Securities Exchange Act of 1934 as a process designed by, or under the supervision of, the companys principal
executive and principal financial officers 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 and includes those policies and procedures that:



| |  |  | Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the
company;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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 its 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. Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control
over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or
improper management override. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known
features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk.

The companys management assessed the effectiveness of the companys internal control over financial reporting as of December 31, 2009. In making this assessment, the companys
management used the criteria set forth in Internal ControlIntegrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on their assessment, the companys management concluded
that, as of December 31, 2009, the companys internal control over financial reporting was effective based on those criteria.

The effectiveness of the companys internal control over financial reporting as of December 31, 2009, has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting
firm, as stated in their report which appears herein.

Report of Independent Registered Public Accounting Firm

To Board of Directors and Shareholders of

Unit Corporation:

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, changes in shareholders equity, and cash flows present fairly, in all material respects, the financial position of Unit Corporation and its subsidiaries at December 31, 2009 and 2008, and the results
of their operations and their cash flows for each of the three years in the period ended December 31, 2009, in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial
statement schedule listed in the index appearing under item 15(a)(2), presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the
Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2009, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO). The Companys management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment
of the effectiveness of internal control over financial reporting, included in the accompanying Managements Report on Internal Control Over Financial Reporting. Our responsibility is to express opinions on these financial statements, on the
financial statement schedule, and on the Companys internal control over financial reporting based on our integrated 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 audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was
maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant
estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk
that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the
circumstances. We believe that our audits provide a reasonable basis for our opinions.

As discussed in Note 2 to the consolidated financial
statements, at December 31, 2009 the Company changed the manner in which it estimates oil and gas reserves.

A companys internal
control over financial reporting is a process 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. A 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 its
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.

UNIT CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1.    ORGANIZATION

Unless the context
clearly indicates otherwise, references in this report to Unit, company, we, our us or like terms refer to Unit Corporation and its subsidiaries.

We are primarily engaged in the land contract drilling of natural gas and oil wells, the exploration, development, acquisition and
production of oil and natural gas properties and the buying, selling, gathering, processing and treating of natural gas. Our operations are located principally in the United States and are organized in the following three reporting segments: (1)
Contract Drilling, (2) Oil and Natural Gas and (3) Mid-Stream.

Contract Drilling.Carried out
by our subsidiary, Unit Drilling Company and its subsidiaries, we contract to drill onshore oil and natural gas wells for our own account and for others. Our current contract drilling operations are conducted in the oil and natural gas producing
provinces of Oklahoma, Texas, Louisiana, Wyoming, Colorado, Utah and North Dakota. We provide land contract drilling services for a wide range of customers.

Oil and Natural Gas.Carried out by our subsidiary, Unit Petroleum Company, we explore, develop, acquire and produce oil and natural gas properties for our own account. Our
primary exploration and production operations are conducted in the Anadarko and Arkoma Basins and in the Texas Gulf Coast area with additional properties in the Permian Basin. The majority of our contract drilling and exploration and production
activities are oriented toward drilling for and producing natural gas.

Mid-Stream.Through our
subsidiary, Superior Pipeline Company, L.L.C. and its subsidiary, we buy, sell, gather, process and treat natural gas for our own account and for third parties. Mid-Stream operations are performed in Oklahoma, Texas, Kansas and Pennsylvania.

NOTE 2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation.The consolidated financial statements include the accounts of Unit
Corporation and its subsidiaries. Our investment in limited partnerships is accounted for on the proportionate consolidation method, whereby our share of the partnerships assets, liabilities, revenues and expenses are included in the
appropriate classification in the accompanying consolidated financial statements.

Certain amounts in the accompanying
consolidated financial statements for prior periods have been reclassified to conform to current year presentation.

Accounting Estimates.    The preparation of financial statements in conformity with generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the
reported amounts of assets and liabilities and 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.

Management has evaluated and disclosed all material subsequent events through February 23, 2010, which is
the date the financial statements in this annual report are filed on Form 10-K.

Drilling
Contracts.    We recognize revenues and expenses generated from daywork drilling contracts as the services are performed, since we do not bear the risk of completion of the well. Under footage and
turnkey contracts, we bear the risk of completion of the well; therefore, revenues and expenses are recognized

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



when the well is substantially completed. Under this method, substantial completion is determined when the well bore reaches the negotiated depth as stated in the contract. The entire amount of a
loss, if any, is recorded when the loss is deter-minable. The costs of uncompleted drilling contracts include expenses incurred to date on footage or turnkey contracts, which are still in process at the end of the period, and
are included in other current assets. Typically, any one of these three types of contracts can be used for the drilling of one well which can take from 20 to 90 days. At December 31, 2009, substantially all of our contracts were daywork contracts of
which 26 were multi-well and had durations which ranged from 6 months to two years. These longer term contracts may contain a fixed rate for the duration of the contract or provide for the periodic renegotiation of the rate within a specific range
from the existing rate.

Cash Equivalents and Book Overdrafts.    We include as cash
equivalents all investments with maturities at date of purchase of three months or less which are readily convertible into known amounts of cash. Book overdrafts are checks that have been issued before the end of the period, but not presented to our
bank for payment before the end of the period. At December 31, 2009 we did not have any book overdrafts and at December 31, 2008, book overdrafts were $48.5 million and included in accounts payable.

Accounts Receivable.Accounts receivable are carried on a gross basis, with no discounting, less an
allowance for doubtful accounts. No allowance for doubtful accounts is recognized at the time the revenue which generates the accounts receivable is recognized. We estimate the allowance for doubtful accounts based on existing economic conditions,
the financial condition of our customers, and the amount and age of past due accounts. Receivables are considered past due if full payment is not received by the contractual due date. Past due accounts are generally written off against the allowance
for doubtful accounts only after all collection attempts have been unsuccessful.

Financial Instruments and
Concentrations of Credit Riskand Non-performance Risk.    Financial instruments, which potentially subject us to concentrations of credit risk, consist primarily of trade receivables with a
variety of oil and natural gas companies. We do not generally require collateral related to receivables. Our credit risk is considered to be limited due to the large number of customers comprising our customer base. During 2009, Questar Corporation
was our largest drilling customer and accounted for approximately 35% of our total contract drilling revenues, there was not a third party customer that accounted for more than 10% of our oil and natural gas revenues and ONEOK, Tenaska and
ConocoPhillips accounted for approximately 52%, 17% and 15% of our mid-stream revenues, respectively. During 2008, Questar Corporation was our largest drilling customer and accounted for approximately 19% of our total contract drilling revenues,
there was not a third party customer that accounted for more than 10% of our oil and natural gas revenues and ONEOK accounted for approximately 79% of our mid-stream revenues, respectively. During 2007, Questar Corporation was our largest drilling
customer and accounted for approximately 13% of our total contract drilling revenues, Eagle Energy Partners I, L.P. accounted for approximately 12% of our oil and natural gas revenues and ONEOK and Murphy Oil USA, Inc. accounted for approximately
82% and 10% of our mid-stream revenues, respectively. We had a concentration of cash of $35.0 million and $3.8 million at December 31, 2009 and 2008, respectively with one bank.

The use of derivative transactions also involves the risk that the counterparties will be unable to meet the financial terms of the
transactions. We considered this non-performance risk with regard to our counterparties and our own non-performance risk in our derivative valuation at December 31, 2009 and determined it was immaterial at that time. At February 12, 2010, Bank of
Montreal, Bank of America, N.A., Calyon New York Branch, Comerica Bank and Compass Bank were the counterparties with respect to all of our commodity derivative transactions. At December 31, 2009, the fair values of the net assets (liabilities) we
had with each of these counterparties was $1.5 million, $6.3 million, $1.0 million, $1.1 million and ($1.4) million, respectively.

Property and Equipment.    Drilling equipment, natural
gas gathering and processing equipment, transportation equipment and other property and equipment are carried at cost. Renewals and improvements are capitalized while repairs and maintenance are expensed. Depreciation of drilling equipment is
recorded using the units-of-production method based on estimated useful lives starting at 15 years, including a minimum provision of 20% of the active rate when the equipment is idle. We use the composite method of depreciation for drill pipe and
collars and calculate the depreciation by footage actually drilled compared to total estimated remaining footage. Depreciation of other property and equipment is computed using the straight-line method over the estimated useful lives of the assets
ranging from 3 to 15 years.

Realization of the carrying value of property and equipment is reviewed for possible impairment
whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Assets are determined to be impaired if a forecast of undiscounted estimated future net operating cash flows directly related to the asset
including disposal value if any, is less than the carrying amount of the asset. If any asset is determined to be impaired, the loss is measured as the amount by which the carrying amount of the asset exceeds its fair value. An estimate of fair value
is based on the best information available, including prices for similar assets. Changes in such estimates could cause us to reduce the carrying value of property and equipment. No significant impairments were recorded at December 31, 2009, 2008 or
2007.

When property and equipment components are disposed of, the cost and the related accumulated depreciation are removed
from the accounts and any resulting gain or loss is generally reflected in operations. For dispositions of drill pipe and drill collars, an average cost for the appropriate feet of drill pipe and drill collars is removed from the asset account and
charged to accumulated depreciation and proceeds, if any, are credited to accumulated depreciation.

We record an asset and a
liability equal to the present value of the expected future asset retirement obligation (ARO) associated with our oil and gas properties. The ARO asset is depreciated in a manner consistent with the depreciation of the underlying physical asset. We
measure changes in the liability due to passage of time by accreting an interest charge. This amount is recognized as an increase in the carrying amount of the liability and as a corresponding accretion expense.

Goodwill.    Goodwill represents the excess of the cost of acquisitions over the fair value of the net
assets acquired. Goodwill is not amortized, but an impairment test is performed at least annually to determine whether the fair value has decreased and is performed additionally when events indicate an impairment may have occurred. Goodwill is all
related to our contract drilling segment, and accordingly, the impairment test is generally based on the estimated discounted future net cash flows of our drilling segment, utilizing discount rates and other factors in determining the fair value of
our drilling segment. No goodwill impairment was recorded for the years ended December 31, 2009, 2008, or 2007. In 2007, we added goodwill of $5.3 million as a result of the acquisition which closed on June 5, 2007. There were no additions to
goodwill in 2008 or 2009. The acquisitions are more fully discussed in Note 3. Goodwill of $7.4 million is deductible for tax purposes.

Intangible Assets.Intangible assets are capitalized and amortized over the estimated period benefited. Such amounts are reviewed for possible impairment whenever
events or changes in circumstances indicate that the carrying amount may not be recoverable. No intangible asset impairment was recorded for the years ended December 31, 2009 or 2008. Amortization of $3.7 million, $4.4 million and $3.3 million was
recorded in 2009, 2008 and 2007, respectively. Accumulated amortization for 2009 and 2008 was $12.3 million and $8.6 million, respectively. Amortization of $2.6 million, $1.2 million, $1.2 million and $0.7 million is expected to be recorded in 2010,
2011, 2012 and 2013, respectively.

Oil and Natural Gas Operations.    We account for our
oil and natural gas exploration and development activities using the full cost method of accounting prescribed by the SEC. Accordingly, all productive and non-productive costs incurred in connection with the acquisition, exploration and development
of our oil and natural gas reserves, including directly related overhead costs and related asset retirement costs, are capitalized and amortized on a composite units-of-production method based on proved oil and natural gas reserves. Directly related
overhead costs of $13.2 million, $15.3 million and $13.1 million were capitalized in 2009, 2008 and 2007, respectively. Independent petroleum engineers annually audit our internal evaluation of our reserves. The average composite rates used for
depreciation, depletion and amortization (DD&A) were $1.87, $2.50 and $2.32 per Mcfe in 2009, 2008 and 2007, respectively. The calculation of DD&A includes estimated future expenditures to be incurred in developing proved reserves and
estimated dismantlement and abandonment costs, net of estimated salvage values. Our undeveloped leasehold properties totaling $140.1 million are excluded from the DD&A calculation.

Our DD&A expense on our oil and natural gas properties is calculated each quarter utilizing period end reserve quantities. The new SEC
oil and gas reserves measurement and disclosure rules that went into effect as of December 31, 2009 impacted our DD&A expense for the fourth quarter of 2009, increasing DD&A expense by $1.2 million (or $0.02 per share) for the quarter and
year ended December 31, 2009.

No gains or losses are recognized on the sale, conveyance or other disposition of oil and
natural gas properties unless a significant reserve amount is involved.

Revenue from the sale of oil and natural gas is
recognized when title passes, net of royalties.

Under the full cost rules, at the end of each quarter, we review the carrying
value of our oil and natural gas properties. The full cost ceiling is based principally on the estimated future discounted net cash flows from our oil and natural gas properties discounted at 10%. Effective December 31, 2009, full cost companies are
required to use the unweighted arithmetic average of the price on the first day of month for each month within the 12-month period prior to the end of the reporting period, unless prices were defined by contractual arrangements, to calculate the
discounted future revenues. Previously, the price was based on the single-day period-end price. In the event the unamortized cost of oil and natural gas properties being amortized exceeds the full cost ceiling, as defined by the SEC, the excess is
charged to expense in the period during which such excess occurs, even if prices are depressed for only a short period of time. Once incurred, a write-down of oil and natural gas properties is not reversible.

We recorded a non-cash ceiling test write down of $281.2 million pre-tax ($175.1 million, net of tax) during the quarter ended March 31,
2009 as a result of a decline in commodity prices as compared to those existing at year end 2008. We recorded a non-cash ceiling test write down of $282.0 million pre-tax ($175.5 million, net of tax) during the year ended December 31, 2008 as a
result of declines in commodity prices. No ceiling test write down was required during the year ended December 31, 2007.

Derivative instruments qualifying as cash flow hedges were included in the computation of limitation on capitalized costs in the March 31, 2009 and December 31, 2008 ceiling test calculations and the effect was a $197.9 million and a $96.0
million, respectively, pre-tax increase in the discounted net cash flows of our oil and natural gas properties. Our qualifying cash flow hedges as of March 31, 2009 which consisted of swaps and collars, covered 30.3 Bcfe and 33.2 Bcfe in 2009 and
2010, respectively, and as of December 31, 2008 covered 40.2 Bcfe and 23.7 Bcfe in 2009 and 2010, respectively.

We did not
have a ceiling test impairment for the quarter ended December 31, 2009. Our qualifying cash flow hedges as of December 31, 2009, which consisted of swaps and collars, covered 36.5 Bcfe in 2010. The

effect of these cash flow hedges was an $88.5 million pre-tax increase in the discounted net cash flows of our oil and natural gas properties. At December 31, 2009, without the benefit of the
discounted value of our commodity hedges, we would have been required to recognize an impairment to our full cost pool of approximately $41.6 million pre-tax ($25.9 million, net of tax). Our oil and natural gas hedging activities are discussed in
Note 13 of our Notes to Consolidated Financial Statements.

Our contract drilling segment provides drilling services for our
exploration and production segment. The contracts for these services are issued under the same conditions and rates as the contracts entered into with unrelated third parties. During 2009, the contract drilling segment drilled 38 wells for our
exploration and production segment. As required by the SEC, the profit received by the contract drilling segment of $1.3 million, $27.9 million and $22.7 million during 2009, 2008 and 2007, respectively, was used to reduce the carrying value of our
oil and natural gas properties rather than being included in its operating profit.

Gas Gathering and Processing
Revenue.    Our gathering and processing segment recognizes revenue from the gathering and processing of natural gas and NGLs in the period the service is provided based on contractual terms.

Insurance.    We are self-insured for certain losses relating to workers compensation, control of
well and employee medical benefits. Insured policies for other coverage contain deductibles or retentions per occurrence that range from $50,000 for fiduciary liability to $1.0 million for drilling rig physical damage. We have purchased stop-loss
coverage in order to limit, to the extent feasible, per occurrence and aggregate exposure to certain types of claims. However, there is no assurance that the insurance coverage will adequately protect us against liability from all potential
consequences. We have elected to use an ERISA governed occupational injury benefit plan to cover all Texas drilling operations in lieu of covering them under Texas Workers Compensation. If insurance coverage becomes more expensive, we may
choose to self-insure, decrease our limits, raise our deductibles or any combination of these rather than pay higher premiums.

Hedging Activities.    All derivatives are recognized on the balance sheet and measured at fair value. If a derivative is designated as a cash flow hedge, we measure the effectiveness of the hedge, or the
degree that the gain (loss) for the hedging instrument offsets the loss (gain) on the hedged item, at each reporting period. The effective portion of the gain (loss) on the derivative instrument is recognized in other comprehensive income as a
component of equity and subsequently reclassified into earnings when the forecasted transaction affects earnings. The ineffective portion of a derivatives change in fair value is required to be recognized in earnings immediately. Derivatives
that do not qualify for hedge treatment are recorded at fair value with gains (losses) recognized in earnings in the period of change.

We document our risk management strategy and hedge effectiveness at the inception of and during the term of each hedge.

Limited Partnerships.    Unit Petroleum Company, is a general partner in 15 oil and natural gas limited partnerships sold privately and publicly. Some of our officers, directors and employees own the
interests in most of these partnerships. We share in each partnerships revenues and costs in accordance with formulas set out in each of the limited partnership agreement. The partnerships also reimburse us for certain administrative costs
incurred on behalf of the partnerships.

Income Taxes.    Measurement of current and
deferred income tax liabilities and assets is based on provisions of enacted tax law; the effects of future changes in tax laws or rates are not included in the measurement. Valuation allowances are established where necessary to reduce deferred tax
assets to the amount expected to be realized. Income tax expense is the tax payable for the year and the change during that year in deferred tax assets and liabilities.

The accounting for uncertainty in income taxes prescribes a recognition threshold and
measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a return. Guidance is also provided on de-recognition, classification, interest and penalties, accounting in interim
periods, disclosure and transition. We have no unrecognized tax benefits and we do not expect any significant changes in unrecognized tax benefits in the next twelve months. In the third quarter of 2007, the Internal Revenue Service completed its
review of our 2004 federal tax return and no adjustments to the return were assessed.

Natural Gas
Balancing.    We use the sales method for recording natural gas sales. This method allows for recognition of revenue, which may be more or less than its share of pro-rata production from certain wells. We estimate our
December 31, 2009 balancing position to be approximately 3.4 Bcf on under-produced properties and approximately 3.3 Bcf on over-produced properties. We have recorded a receivable of $1.5 million on certain wells where we estimate that insufficient
reserves are available for us to recover the under-production from future production volumes. We have also recorded a liability of $3.3 million on certain properties where we believe there are insufficient reserves available to allow the
under-produced owners to recover their under-production from future production volumes. Our policy is to expense the pro-rata share of lease operating costs from all wells as incurred. Such expenses relating to the balancing position on wells in
which we have imbalances are not material.

Employee and Director Stock Based
Compensation.    We recognize in our financial statements the cost of employee services received in exchange for awards of equity instruments based on the grant date fair value of those awards. The amount of our equity
compensation cost relating to employees directly involved in our oil and natural gas segment is capitalized to our oil and natural gas properties. Amounts not capitalized to our oil and natural gas properties are recognized in general and
administrative expense and operating costs of our business segments. We utilize the Black-Scholes option pricing model to measure the fair value of stock options and stock appreciation rights (SARs). The value of our restricted stock grants is based
on the closing stock price on the date of the grants.

Impact of Financial Accounting Pronouncements.

The FASB Accounting Standards Codification.FASB Accounting Standards Codification (ASC) became effective
during the third quarter of 2009. ASC 105,Generally Accepted Accounting Principles, (guidance formerly reflected in FAS168) established the ASC as the single source of authoritative U.S. generally accepted accounting principles
(U.S. GAAP) recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the SEC under authority of federal securities laws are also sources of authoritative U.S. GAAP for SEC registrants. The ASC supersedes
all existing non-SEC accounting and reporting standards. All other nongrandfathered non-SEC accounting literature not included in the ASC will become nonauthoritative. Following ASC 105, the FASB will not issue new standards in the form of
Statements, FASB Staff Positions, or Emerging Issues Task Force Abstracts. Instead, the FASB will issue Accounting Standards Updates, which will serve only to: (a) update the ASC; (b) provide background information about the guidance;
and (c) provide the basis for conclusions on the change(s) in the ASC. The adoption of this standard has changed how we reference various elements of U.S. GAAP in our financial statement disclosures, but has no impact on our financial
position, results of operation or cash flows.

Fair Value Measurements and
Disclosures.Beginning in 2008, we adopted the effective provisions of ASC 820 Fair-Value Measurements (formerly FAS 157.) ASC 820 defines fair value in applying GAAP, establishes a framework for measuring fair
value and expands disclosures about fair-value measurements. ASC 820 does not change existing guidance as to whether or not an instrument is carried at fair value.

UNIT CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



In February 2008, the FASB delayed the effective date of ASC 820 for one year for
certain nonfinancial assets and nonfinancial liabilities, except those recognized or disclosed at fair value in the financial statements on a recurring basis. On January 1, 2009, we adopted, the delayed provisions of ASC 820 related to nonfinancial
assets and nonfinancial liabilities that are not required or permitted to be measured at fair value on a recurring basis. The adoption of the delayed provisions did not have a material impact on our financial statements.

Modernization of Oil and Gas Reporting.On December 31, 2008, the Securities and Exchange Commission (SEC)
adopted major revisions to its rules governing oil and gas company reporting requirements. These include provisions that permit the use of new technologies to determine proved reserves, and that allow companies to disclose their probable and
possible reserves to investors. The current rules limit disclosure to only proved reserves. The new rules also require companies to report the independence and qualifications of the auditor of the reserve estimates and file reports when a third
party is relied on to prepare reserves estimates. The new rules also require that oil and gas reserves be reported and the full cost ceiling value calculated using an average price based on the first-of-month posted price for each month in the prior
12-month period. On January 5, 2010, the FASB issued Accounting Standards update (ASU) 2010-03Extractive ActivitiesOil and Gas (ASC932): Oil and Gas Reserve Estimation and Disclosures, an update of ASC 932
Extractive ActivitiesOil and Gas, which subsequently aligns the reserve estimation, disclosure requirements, and definitions of ASC 932 with the disclosure requirements of the new rules issued by the SEC. The new oil and gas reserve
measurement and reporting requirements were adopted for oil and gas reserves as of December 31, 2009. For accounting purposes, the new requirements constitute a change in accounting principle inseparable from a change in estimate. As such, prior
reserve disclosures were not modified and the impact of the new requirements on our oil and gas reserves was reflected as a change in estimate. As previously noted, reserves and discounted cash flows prepared using the new rules were used in the
calculation of DD&A for the fourth quarter of 2009 and the ceiling test at December 31, 2009.

Interim Disclosures
about Fair Value of Financial Instruments.On June 30, 2009, we implemented certain provisions of ASC 825, Financial Instruments, (guidance formerly reflected in FASB Staff Position (FSP) Statement No. 107-1 and
Accounting Principles Board (APB) 28-1, Interim Disclosures about Fair Value of Financial Instruments). The new provisions require disclosures about fair value of financial instruments in interim financial information. We are required to
disclose in the body or in the accompanying notes of our summarized financial information for interim reporting periods and in our financial statements for annual reporting periods, the fair value of all financial instruments for which it is
practicable to estimate that value, whether recognized or not recognized in the statement of financial position. We have included the required disclosure in Note 6 of our Notes to Consolidated Financial Statements.

Subsequent Events.On June 30, 2009, we implemented certain provisions of ASC 855, Subsequent Events,
(guidance formerly reflected in FAS165, Subsequent Events).The new provision establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or are
available to be issued. ASC 855 provides:



| |  |  | The period after the balance sheet date during which management of a reporting entity should evaluate events or transactions that may occur for
potential recognition or disclosure in the financial statements;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The circumstances under which an entity should recognize events or transactions occurring after the balance sheet date in its financial statements; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The disclosures that an entity should make about events or transactions that occurred after the balance sheet date.
| | - |  | -------------------------------------------------------------------------------------------------------------------

Consolidations of Variable Interest Entities.On June 12, 2009, the FASB issued ASU
2009-17Consolidations (ASC 810): Improvements to Financial Reporting by Enterprises Involved with Variable Interest



80

##### Table of Contents

UNIT CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



Entities, the FASB amended the authoritative guidance on consolidation which requires an enterprise to perform an analysis to determine whether the enterprises variable interest or
interests give it a controlling financial interest in a variable interest entity. In order to be the primary beneficiary of a variable interest entity, an enterprise must have (a) the power to direct the activities of a variable interest entity
that most significantly impact the entitys economic performance, and (b) the obligation to absorb losses of the entity that could potentially be significant to the variable interest entity or the right to receive benefits from the entity
that could potentially be significant to the variable interest entity. Along with these criteria, an enterprise is now required to assess whether it has an implicit financial responsibility to ensure that a variable interest entity operates as
designed when determining (a) above. Also, the enterprise is required to perform ongoing reassessments of whether an enterprise is the primary beneficiary of a variable interest entity. The quantitative approach previously required for
determining the primary beneficiary has been eliminated. Additional disclosures are now required in order to provide users of financial statements with more transparent information about an enterprises involvement in a variable interest
entity. This amendment is effective for the first fiscal year beginning after November 15, 2009. This ASU does not currently have a material impact on us.

Improving Disclosures about Fair Value Measurements.In January 2010, the FASB issued ASU 2010-06 Fair Value Measurements and Disclosures (ASC 820): Improving
Disclosures about Fair Value Measurements, which provides additional guidance to improve disclosures regarding fair value measurements. The ASU amends ASC 820-10, Fair Value Measurements and DisclosuresOverall (formerly FAS 157,
Fair Value Measurements) to add two new disclosures: (1) transfers in and out of Level 1 and 2 measurements and the reasons for the transfers, and (2) a gross presentation of activity within the Level 3 roll forward. The ASU also
includes clarifications to existing disclosure requirements on the level of disaggregation and disclosures regarding inputs and valuation techniques. The ASU applies to all entities required to make disclosures about recurring and nonrecurring fair
value measurements. The effective date of the ASU is the first interim or annual reporting period beginning after December 15, 2009, except for the gross presentation of the Level 3 roll forward information, which is required for annual
reporting periods beginning after December 15, 2010 and for interim reporting periods within those years. This statement will not have a significant impact on us due to it only requiring enhanced disclosures.

NOTE 3.    ACQUISITIONS

During 2008 and 2009, we acquired interests in approximately 60,000 net undeveloped acres in the Marcellus Shale Play, located mainly in Pennsylvania and Maryland for approximately $43.6 million. In July
2009, we received $7.1 million and approximately 1,500 net undeveloped acres, representing payment for our 50% interest in 4,000 gross undeveloped acres and reimbursement for costs we paid on their behalf. On September 30, 2009, per our
agreement with certain unaffiliated third parties, we were paid approximately $14.9 million for our 50% interest in approximately 18,000 gross undeveloped acres of the Marcellus Shale and $26.1 million for a receivable from the third parties for
their 50% share of the costs we paid on their behalf to acquire the acreage. The sales proceeds reduced undeveloped leasehold and no gain or loss was recorded on this sale. We now have an interest in approximately 50,500 net undeveloped acres.

In September 2008, we completed an acquisition consisting of a 75% working interest in four producing wells and other proved
undeveloped properties for $22.2 million along with working interests in undeveloped leasehold valued at approximately $3.5 million, all located in the Texas Panhandle region.

On January 18, 2008, we purchased a 50% interest in a 6,800 gross-acre leasehold that we did not already own in our Segno area of
operations located in Hardin County, Texas. Included in the purchase were five producing wells with 4.9 Bcfe of estimated proved reserves and current production of 2.8 MMcf of natural gas per day and 88.2 barrels of condensate. The purchase price
was $16.8 million which consisted of $15.8 million allocated to the reserves of the wells and $1.0 million allocated to the undeveloped leasehold.

On June 5, 2007, our subsidiary, Unit Drilling Company, closed the purchase of a
privately owned drilling company operating primarily in the Texas Panhandle. This acquisition included nine drilling rigs, drill pipe and collars, a fleet of 11 trucks, an office, shop, equipment yard and personnel. The drilling rigs range from 800
horsepower to 1,000 horsepower with depth capacities rated from 10,000 to 15,000 feet. Eight of the acquired drilling rigs were operational at the time of purchase and the remaining drilling rig is being refurbished and is anticipated to become
operational in March of 2008. The financial results of this acquisition are included in our statement of income from June 5, 2007 forward. The total consideration paid in this acquisition was allocated as follows (in thousands):

On December 23, 2008, we entered into a First
Amendment to our existing First Amended and Restated Senior Credit Agreement (Credit Facility) with a maximum credit amount of $400.0 million maturing on May 24, 2012. This amendment increased the lenders commitment by $50.0 million to an
aggregate of $325.0 million. Borrowings under the Credit Facility are limited to a commitment amount that we can elect. As of December 31, 2009, the commitment amount was $325.0 million. We are charged a commitment fee of 0.375 to 0.50 of 1% on
the amount available but not borrowed with the rate varying based on the amount borrowed as a percentage of the total borrowing base amount. When we entered into the Credit Facility, we incurred origination, agency and syndication fees of $737,500
and $478,125 associated with the December 23, 2008 First Amendment, which are being amortized over the life of the agreement. The average interest rate for 2009, which includes the effect of our interest rate swaps, was 4.0%.

The lenders aggregate commitment is limited to the lesser of the amount of the value of the borrowing base or $400.0 million. The
amount of the borrowing base, which is subject to redetermination on April 1 and

##### Table of Contents

UNIT CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



October 1 of each year, is based primarily on a percentage of the discounted future value of our oil and natural gas reserves and, to a lesser extent, the loan value the lenders reasonably
attribute to the cash flow (as defined in the Credit Facility) of our mid-stream operations. The current borrowing base is $475.0 million. We or the lenders may request a onetime special redetermination of the borrowing base amount between each
scheduled redetermination. In addition, we may request a redetermination following the consummation of an acquisition meeting the requirements defined in the Credit Facility.

At our election, any part of the outstanding debt under the Credit Facility may be fixed at a London Interbank Offered Rate (LIBOR) for a
30, 60, 90 or 180 day term. During any LIBOR funding period, the outstanding principal balance of the promissory note to which the LIBOR option applies may be repaid on three days prior notice to the administrative agent and on our payment of any
applicable funding indemnification amounts. Interest on the LIBOR is computed at the LIBOR base applicable for the interest period plus 1.75% to 2.50% depending on the level of debt as a percentage of the borrowing base and payable at the end of
each term, or every 90 days, whichever is less. Borrowings not under LIBOR bear interest at the BOK Financial Corporation (BOKF) National Prime Rate, which in no event will be less than LIBOR plus 1.00%, payable at the end of each month and the
principal borrowed may be paid at any time, in part or in whole, without a premium or penalty. At December 31, 2009, all of our then outstanding borrowings of $30.0 million were subject to LIBOR.

The Credit Facility prohibits:



| |  |  | the payment of dividends (other than stock dividends) during any fiscal year in excess of 25% of our consolidated net income for the preceding fiscal
year;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the incurrence of additional debt with certain limited exceptions; and
| | - |  | ----------------------------------------------------------------------



| |  |  | the creation or existence of mortgages or liens, other than those in the ordinary course of business, on any of our properties, except in favor of our
lenders.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------

The Credit Facility also requires that we have at the end of each quarter:



| |  |  | consolidated net worth of at least $900 million;
| | - |  | ------------------------------------------------



| |  |  | a current ratio (as defined in the Credit Facility) of not less than 1 to 1; and
| | - |  | --------------------------------------------------------------------------------



| |  |  | a leverage ratio of long-term debt to consolidated EBITDA (as defined in the Credit Facility) for the most recently ended rolling four fiscal quarters
of no greater than 3.50 to 1.0.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As of December 31, 2009, we were in compliance with the covenants of
the Credit Facility.

Based on the borrowing rates currently available to us for debt with similar terms and maturities and
consideration of our non-performance risk, long-term debt at December 31, 2009 and 2008 approximates its fair value.

At
December 31, 2009, the carrying values of cash and cash equivalents, accounts receivable, accounts payable, other current assets and current liabilities on the consolidated balance sheets approximate fair value because of their short term
nature.

NOTE 7.    ASSET RETIREMENT OBLIGATIONS

We are
required to record the fair value of liabilities associated with the retirement of long-lived assets. Our oil and natural gas wells are required to be plugged and abandoned when the oil and natural gas reserves in the wells are depleted or the wells
are no longer able to produce. The plugging and abandonment expense for a well is recorded in the period in which the liability is incurred (at the time the well is drilled or acquired). We do not have any assets restricted for settling these
well ARO liabilities.

The following table shows the activity for our retirement obligation for plugging liability for the
years ending December 31:

Realization of the deferred tax assets are dependent on generating sufficient future taxable income.
Although realization is not assured, management believes it is more likely than not that the deferred tax asset will be realized. The amount of the deferred tax asset considered realizable, however, could be reduced in the near-

term if estimates of future taxable income are reduced. At December 31, 2009, we have net operating loss carryforwards of approximately $5.4 million which expire from 2015 to 2021.

NOTE 9.    EMPLOYEE BENEFIT PLANS

Under our 401(k) Employee Thrift Plan, employees who meet specified service requirements may contribute a percentage of their total
compensation, up to a specified maximum, to the plan. We may match each employees contribution, up to a specified maximum, in full or on a partial basis. We made discretionary contributions under the plan of 202,655, 89,910 and 83,277 shares
of common stock and recognized expense of $3.6 million, $5.0 million and $4.8 million in 2009, 2008 and 2007, respectively.

We provide a salary deferral plan (Deferral Plan) which allows participants to defer the recognition of salary for income tax purposes until actual distribution of benefits which occurs at either termination of employment, death or certain
defined unforeseeable emergency hardships. The liability recorded under the Deferral Plan at December 31, 2009 and 2008 was $2.0 million for both years. We recognized payroll expense and recorded a liability at the time of deferral.

Effective January 1, 1997, we adopted a separation benefit plan (Separation Plan). The Separation Plan allows eligible employees
whose employment is involuntarily terminated or, in the case of an employee who has completed 20 years of service, voluntarily or involuntarily terminated, to receive benefits equivalent to four weeks salary for every whole year of service completed
up to a maximum of 104 weeks. To receive payments, the recipient must waive any claims against us in exchange for receiving the separation benefits. On October 28, 1997, we adopted a Separation Benefit Plan for Senior Management (Senior Plan).
The Senior Plan provides certain officers and key executives of Unit with benefits generally equivalent to the Separation Plan. The Compensation Committee of the Board of Directors has absolute discretion in the selection of the individuals covered
in this plan. On May 5, 2004 we also adopted the Special Separation Benefit Plan (Special Plan). This plan is identical to the Separation Benefit Plan with the exception that the benefits under the plan vest on the earliest of a
participants reaching the age of 65 or serving 20 years with the company.

On December 31, 2008, we amended all
three Plans to be in compliance with Section 409A of the Internal Revenue Code of 1986, as amended. The key amendments to the Plans address, among other things, when distributions may be made, the timing of payments, and the circumstances under
which employees become eligible to receive benefits. None of the amendments materially increase the benefits, grants or awards issuable under the Plans. We recognized expense of $1.5 million, $1.6 million and $1.5 million in 2009, 2008 and 2007,
respectively, for benefits associated with anticipated payments from these separation plans.

We have entered into key
employee change of control contracts with three of our current executive officers. These severance contracts have an initial three-year term that is automatically extended for one year on each anniversary, unless a notice not to extend is given by
us. If a change of control of the company, as defined in the contracts, occurs during the term of the severance contract, then the contract becomes operative for a fixed three-year period. The severance contracts generally provide that the
executives terms and conditions for employment (including position, work location, compensation and benefits) will not be adversely changed during the three-year period after a change of control. If the executives employment is
terminated (other than for cause, death or disability), the executive terminates for good reason during such three-year period, or the executive terminates employment for any reason during the 30-day period following the first anniversary of the
change of control, and on certain terminations prior to a change of control or in connection with or in anticipation of a change of control, the executive is generally entitled to receive, in addition to certain other benefits, any earned but unpaid
compensation; up to 2.9 times the executives base salary plus annual bonus (based on historic annual bonus); and the company matching contributions that would have been made had the executive continued to participate in the companys
401(k) plan for up to an additional three years.

The severance contract provides that the executive is entitled to receive a payment in
an amount sufficient to make the executive whole for any excise tax on excess parachute payments imposed under Section 4999 of the Code. As a condition to receipt of these severance benefits, the executive must remain in the employ of the
company prior to change of control and render services commensurate with his position.

NOTE 10.    TRANSACTIONS
WITH RELATED PARTIES

Unit Petroleum Company serves as the general partner of 15 oil and gas limited partnerships.
Three were formed for investment by third parties and eleven (the employee partnerships) were formed to allow certain of our qualified employees and our directors to participate in Unit Petroleums oil and gas exploration and production
operations. The partnerships for the third party investments were formed in 1984 and 1986. An additional third party partnership, the 1979 Oil and Gas Limited Partnership was dissolved on July 1, 2003. Employee partnerships have been formed for
each year beginning with 1984. Interests in the employee partnerships were offered to the employees of Unit and its subsidiaries whose annual base compensation was at least a specified amount ($36,000 for 2009, 2008 and 2007) and to the directors of
Unit.

The employee partnerships formed in 1984 through 1990 were consolidated into a single consolidating partnership in 1993
and the employee partnerships formed in 1991 through 1999 were also consolidated into the consolidating partnership in 2002. The consolidation of the 1991 through the 1999 employee partnerships was done by the general partners under the authority
contained in the respective partnership agreements and did not involve any vote, consent or approval by the limited partners. The employee partnerships have each had a set percentage (ranging from 1% to 15%) of our interest in most of the oil and
natural gas wells we drill or acquire for our own account during the particular year for which the partnership was formed. The total interest the employees have in our oil and natural gas wells by participating in these partnerships does not exceed
one percent.

Amounts received in the years ended December 31, from both public and private Partnerships for which Unit
is a general partner are as follows:



|                                                 |  |                |     |      |   |      |  |   |

|                                                 |  | (In thousands)
|Contract drilling                                |  | $              | 368 |      | $ | 916  |  | $ | 729
|Well supervision and other fees                  |  | $              | 352 |      | $ | 375  |  | $ | 377
|General and administrative expense reimbursement |  | $              | 376 |      | $ | 584  |  | $ | 444

Related party
transactions for contract drilling and well supervision fees are the related partys share of such costs. These costs are billed to related parties on the same basis as billings to unrelated parties for such services. General and administrative
reimbursements are both direct general and administrative expense incurred on the related partys behalf and indirect expenses allocated to the related parties. Such allocations are based on the related partys level of activity and are
considered by management to be reasonable.

NOTE 11.    SHAREHOLDER RIGHTS PLAN

We maintain a Shareholder Rights Plan (the Plan) designed to deter coercive or unfair takeover tactics, to prevent a person or group from
gaining control of us without offering fair value to all our shareholders and to deter other abusive takeover tactics, which are not in the best interest of shareholders.

Under the terms of the Plan, each share of common stock is accompanied by one right, which given certain acquisition and business combination criteria, entitles the shareholder to purchase from us one
one-hundredth of

a newly issued share of Series A Participating Cumulative Preferred Stock at a price subject to adjustment by us or to purchase from an acquiring company certain shares of its common stock or the
surviving companys common stock at 50% of its value.

The rights become exercisable 10 days after we learn that an
acquiring person (as defined in the Plan) has acquired 15% or more of the outstanding common stock of Unit or 10 business days after the commencement of a tender offer, which would result in a person owning 15% or more of our shares. We can redeem
the rights for $0.01 per right at any date before the earlier of (i) the close of business on the 10th day following the time we learn that a person has become an acquiring person or (ii) May 19, 2015 (the Expiration
Date). The rights will expire on the Expiration Date, unless redeemed earlier by Unit.

NOTE
12.    STOCK-BASED COMPENSATION

In 2009, 2008 and 2007, we recognized stock compensation expense
for restricted stock awards, stock options and SARs of $9.2 million, $11.1 million and $4.8 million, respectively, and capitalized stock compensation cost for oil and natural gas properties of $2.1 million, $3.3 million and $1.2 million,
respectively. The tax benefit related to this stock based compensation was $2.6 million, $4.1 million and $2.1 million, respectively. The remaining unrecognized compensation cost related to unvested awards at December 31, 2009 is approximately
$4.9 million with $1.1 million of this amount anticipated to be capitalized. The weighted average period of time over which this cost will be recognized is 0.4 years.

The following table estimates the fair value of each option and SARs granted under all of our plans during the twelve month periods ending December 31, using the Black-Scholes model applying the
estimated values presented in the table:

Expected volatilities are
based on the historical volatility of our stock. We use historical data to estimate option exercise and employee termination rates within the model and aggregate groups of employees that have similar historical exercise behavior for valuation
purposes. To date, we have not paid dividends on our stock. The risk free interest rate is computed from the United States Treasury Strips rate using the term over which it is anticipated the grant will be exercised.

At our annual meeting on May 3, 2006, our shareholders approved the Unit Corporation Stock and Incentive Compensation Plan. This plan
allows for the issuance of 2.5 million shares of common stock with 2.0 million shares being the maximum number of shares that can be issued as incentive stock options. Awards under this plan may be granted in any one or a
combination of the following:



| |  |  | incentive stock options under Section 422 of the Internal Revenue Code;
| | - |  | -----------------------------------------------------------------------



| |  |  | non-qualified stock options;

This plan also contains various limits as to the amount of awards that can be given to an employee in any fiscal year. All awards are generally subject to the minimum vesting periods, as determined by our
Compensation Committee and included in the award agreement.

During 2009, there were 116,826 shares of other stock-based
awards issued under this plan. These shares vested immediately and the fair value on the grant date was $3.3 million.

There were no SARs granted in 2009 or 2008. The SARs
granted in 2007 vest in thirds annually with the first vesting period on January 5, 2009. The SARs expire after 10 years from the date of the grant. In 2009 and 2008, 48,633 shares and 14,891 shares vested and no shares vested in 2007. Fair
value of SARs at grant date in 2007 was $2.3 million. The aggregate intrinsic value of the 145,901 shares outstanding subject to vesting at December 31, 2009 was zero with a weighted average remaining contractual term of 7.7 years.

The restricted stock awards vest in periods ranging
from one to three years. There was no restricted stock granted in 2009. The fair value of the restricted stock granted in 2008 and 2007 at the grant date was $1.5 million and $26.3 million, respectively. The aggregate intrinsic value of the 68,836
shares of restricted stock on their 2009 vesting date was $2.0 million. The aggregate intrinsic value of the 507,071 shares outstanding subject to vesting at December 31, 2009 was $21.6 million with a weighted average remaining life of 0.6
years.

As a result of the approval of the adoption of the Unit Corporation Stock and Incentive Compensation Plan at our
shareholders annual meeting on May 3, 2006, no further grants were made under the prior Employee Stock Bonus Plan. Under the terms of the old plan, awards were granted to employees in either cash or stock or a combination thereof, and
were payable in a lump sum or in installments subject to certain restrictions. On December 13, 2005, 38,190 shares (in the form of restricted stock awards) were granted under the plan one half of which was distributed on January 1,
2007 and the other half was distributed on January 1, 2008. No shares vested in 2006.

The grant date fair value of the 18,749 shares vesting
in 2007 and the 18,374 shares vesting in 2008 was $1.0 million each. As of December 31, 2008 all shares in this plan have been vested or forfeited.

We also have a Stock Option Plan, which provided for the granting of options for up to 2,700,000 shares of common stock to officers and employees. The option plan permitted the issuance of qualified or
nonqualified stock options. Options granted typically become exercisable at the rate of 20% per year one year after being granted and expire after 10 years from the original grant date. The exercise price for options granted under this plan is
the fair market value of the common stock on the date of the grant. As a result of the approval of the adoption of the Unit Corporation Stock and Incentive Compensation Plan, no further awards will be made under this plan.

$2.8 million with a weighted average remaining contractual term of 4.1 years.

On May 29, 2009, our company through its
compensation committee and board of directors, approved amendments to the existing Unit Corporation 2000 Non-Employee Directors Stock Option Plan. The amendments extended the plan term from May 30, 2010 to May 30, 2017, and increased
the aggregate number of shares that may be issued or delivered due to exercise of non-employee director option awards from 210,000 shares of common stock to 510,000 shares of common stock. Under the plan, on the first business day following each
annual meeting of shareholders, each person who was then a member of our Board of Directors and who was not then an employee of the company or any of its subsidiaries was granted an option to purchase 3,500 shares of common stock. The option price
for each stock option is the fair market value of the common stock on the date the stock options are granted. The term of each option is 10 years and cannot be increased and no stock options may be exercised during the first six months of its term
except in case of death.

On the first day following the 2009 annual meeting, each non-employee director was granted 437
shares of common stock. Effective with the adoption of the amendments mentioned above, a contingent one-time grant of 3,063 shares to each non-employee director was made on May 29, 2009. These contingent option awards cannot vest before the
stockholders approve the amended plan at the next stockholders annual meeting, and will be void in the event such approval is not obtained.

NOTE
13.    DERIVATIVES

On January 1, 2009, we implemented new accounting guidance which requires
enhanced disclosures about a companys derivative activities and how the related hedged items affect a companys financial position, financial performance and cash flows.

Interest Rate Swaps

From time to time we have entered into interest
rate swaps to help manage our exposure to possible future interest rate increases. Under these transactions we have swapped the variable interest rate we would otherwise incur on a portion of our bank debt for a fixed interest rate. As of
December 31, 2009, we had two outstanding interest rate swaps both of which were cash flow hedges. There was no material amount of ineffectiveness.

Commodity Derivatives

We have entered into various types of derivative instruments covering a portion of our projected natural gas, natural
gas liquids and oil production to reduce our exposure to market price volatility. Our decision on the quantity and price at which we choose to hedge certain of our production is based, in part, on our view of current and future market conditions. As
of December 31, 2009, our derivative instruments consisted of the following types of swaps and collars:



| |  |  | Swaps. We receive or pay a fixed price for the hedged commodity and pay or receive a floating market price to the counterparty. The fixed-price
payment and the floating-price payment are netted, resulting in a net amount due to or from the counterparty.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Collars. A collar contains a fixed floor price (put) and a ceiling price (call). If the market price exceeds the call strike price or falls
below the put strike price, we receive the fixed price and pay the market price. If the market price is between the call and the put strike price, no payments are due from either party.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Basis Swaps.We receive or pay the NYMEX settlement value plus or minus a fixed delivery point price for the hedged commodity and pay or receive
the published index price at the specified delivery point. We use basis swaps to hedge the price risk between NYMEX and its physical delivery points.

UNIT CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



We recognize the effective portion of changes in fair value as accumulated other
comprehensive income (loss) (OCI), and reclassify the recognized gains (losses) on the sales to revenue and the purchases to expense as the underlying transactions are settled. As of December 31, 2009 and 2008, we had a gain of $4.5 million and
$33.3 million, net of tax, respectively, in accumulated OCI.

Based on the market prices at December 31, 2009, we expect
to transfer approximately $4.7 million, net of tax, of the gain included in the balance in accumulated OCI to earnings during the next 12 months in the related month of settlement. The interest rate swaps and the commodity derivative instruments as
of December 31, 2009 are expected to mature by May 2012 and December 2010, respectively.

Certain derivatives
do not qualify for designation as cash flow hedges. We had two basis swaps that did not qualify as cash flow hedges that expired in December 2009. Changes in the fair value of these non-qualifying derivatives that occur before their maturity (i.e.,
temporary fluctuations in value) are reported in the consolidated statements of operations within oil and natural gas revenues. 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 OCI until the hedged item is recognized into earnings. Any change in fair value resulting from ineffectiveness is recognized in oil and natural gas revenues.

NOTE 14.    FAIR VALUE MEASUREMENTS

Fair value is defined as the amount that would be received from the sale of an asset or paid for the transfer of a liability
in an orderly transaction between market participants (an exit price). To estimate an exit price, a three-level hierarchy is used prioritizing the valuation techniques used to measure fair value into three levels with the highest priority given to
Level 1 and the lowest priority given to Level 3. The levels are summarized as follows:



| |  |  | Level 1unadjusted quoted prices in active markets for identical assets and liabilities.
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | Level 2significant observable pricing inputs other than quoted prices included within level 1 that are either directly or indirectly observable
as of the reporting date. Essentially, inputs (variables used in the pricing models) that are derived principally from or corroborated by observable market data.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 3generally unobservable inputs which are developed based on the best information available and may include our own internal data.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------

The inputs available to us determine the valuation technique we use to measure the fair values of our
financial instruments.

The following tables set forth our recurring fair value measurements:

The following methods and assumptions were used to estimate the fair values of the
assets and liabilities in the table above.

Level 2 Fair Value Measurements

Commodity Derivatives. The fair values of our crude oil swaps are measured using estimated internal discounted cash flow calculations
using NYMEX futures index.

Level 3 Fair Value Measurements

Interest Rate Swaps.The fair values of our interest rate swaps are based on estimates provided by our respective counterparties and
reviewed internally using established index prices and other sources.

Commodity Derivatives. The fair values of our
natural gas and natural gas liquids swaps, basis swaps and crude oil and natural gas collars are estimated using internal discounted cash flow calculations based on forward price curves, quotes obtained from brokers for contracts with similar terms
or quotes obtained from counterparties to the agreements.

The following tables are reconciliations of our level 3 fair value
measurements:

We
evaluated the non-performance risk with regard to our counterparties and our own non-performance risk in our valuation at December 31, 2009 and determined it was immaterial.

NOTE 15.    COMMITMENTS AND CONTINGENCIES

We
lease office space or yards in Tulsa, Oklahoma; Houston, Texas; Englewood and Denver, Colorado; Pinedale, Wyoming; and Pittsburgh, Pennsylvania under the terms of operating leases expiring through January, 2012. Additionally, we have several
equipment leases and lease space on short-term commitments to stack

excess drilling rig equipment and production inventory.Future minimum rental payments under the terms of the leases are approximately $0.6 million, $0.4 million and $0.1 million in
2010, 2011 and 2012, respectively. Total rent expense incurred was $2.1 million, $2.1 million and $1.7 million in 2009, 2008 and 2007, respectively.

The Unit 1984 Oil and Gas Limited Partnership and the 1986 Energy Income Limited Partnership agreements along with the employee oil and gas limited partnerships require, on the election of a limited
partner, that we repurchase the limited partners interest at amounts to be determined by appraisal in the future. These repurchases in any one year are limited to 20% of the units outstanding. We made repurchases of $1,000 and $241,000 in 2009
and 2008, respectively, and had no repurchases in 2007.

We manage our exposure to environmental liabilities on properties to
be acquired by identifying existing problems and assessing the potential liability. We also conduct periodic reviews, on a company-wide basis, to identify changes in our environmental risk profile. These reviews evaluate whether there is a probable
liability, its amount, and the likelihood that the liability will be incurred. The amount of any potential liability is determined by considering, among other matters, incremental direct costs of any likely remediation and the proportionate cost of
employees who are expected to devote a significant amount of time directly to any possible remediation effort. As it relates to evaluations of purchased properties, depending on the extent of an identified environmental problem, we may exclude a
property from the acquisition, require the seller to remediate the property to our satisfaction, or agree to assume liability for the remediation of the property.

We have not historically experienced any environmental liability while being a contract driller since the greatest portion of risk is borne by the operator. Any liabilities we have incurred have been
small and have been resolved while the drilling rig is on the location and the cost has been included in the direct cost of drilling the well.

For the next twelve months, we have committed to purchase approximately $18.8 million of new drilling rig components, drill pipe, drill collars and related equipment and $0.5 million of casing.

We are subject to various legal proceedings arising in the ordinary course of our various businesses none of which, in our
opinion, will result in judgments which would have a material adverse effect on our financial position, operating results or cash flows.

NOTE 16.    INDUSTRY SEGMENT INFORMATION

We have three business segments: contract
drilling, oil and natural gas exploration and mid-stream operations, representing our three main business units offering different products and services. The contract drilling segment is engaged in the land contract drilling of oil and natural gas
wells, the oil and natural gas exploration segment is engaged in the development, acquisition and production of oil and natural gas properties and the mid-stream segment is engaged in the buying, selling, gathering, processing and treating of
natural gas.

The accounting policies of the segments are the same as those described in the Summary of Significant
Accounting Policies (Note 2). We evaluate the performance of our business segments based on operating income, which is defined as operating revenues less operating expenses and depreciation, depletion and amortization. We also have some
natural gas production in Canada, which is not significant.

NOTE 18.    SUBSEQUENT EVENTS

In January and February 2010, our contract drilling segment entered into contracts to sell eight of its idle mechanical drilling rigs to an
unaffiliated third party. These drilling rigs ranged in horse power from 800 to 1,000. The closing on three of these drilling rigs occurred in February. Three more are scheduled to close during the first quarter of 2010 with the last
transaction for the remaining two rigs anticipated to close during the second quarter of 2010. Proceeds from the sale of all the drilling rigs will be $23.9 million resulting in an estimated gain

of $6.1 million. The proceeds from this sale will be used to refurbish and upgrade additional rigs in our fleet in order that those rigs can be used in horizontal drilling operations. We also
placed into service in our Rocky Mountain division a 1,500 horsepower, diesel-electric drilling rig that previously had been placed on hold during 2009 by our customer. At completion of the sale of the eight rigs and with the additional rig recently
placed into service, this segment will have 123 drilling rigs in its fleet.

Unproved properties
not subject to amortization relates to properties which are not individually significant and consist primarily of lease acquisition costs. The evaluation process associated with these properties has not been completed and therefore, the company is
unable to estimate when these costs will be included in the amortization calculation.

|(3) | Reflects the effects of new oil and gas reserve measurement requirements. Reserve quantities at December 31, 2009 under the previous reporting rules are 12,066
Bbls, 15,106 Bbls and 438,551 Mcf for oil, liquids and natural gas, respectively.

|(4) | As a result of processing more natural gas liquids out of our natural gas, revisions of previous estimates reflect an increase in NGLs derived from natural gas.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------

Estimates of oil, NGLs and natural gas reserves require extensive judgments of reservoir engineering data.
Assigning monetary values to such estimates does not reduce the subjectivity and changing nature of such reserve estimates. Indeed the uncertainties inherent in the disclosure are compounded by applying additional estimates of the rates and timing
of production and the costs that will be incurred in developing and producing the reserves. The information set forth in this report is, therefore, subjective and, since judgments are involved, may not be comparable to estimates submitted by other
oil and natural gas producers. In addition, since prices and costs do not remain static and no price or cost escalations or de-escalations have been considered, the results are not necessarily indicative of the estimated fair market value of
estimated proved reserves, nor of estimated future cash flows.

The standardized measure of discounted future net cash flows
(SMOG) was calculated using 12-month average prices and year-end costs and statutory tax rates, adjusted for permanent differences that relate to existing proved oil, NGLs and natural gas reserves. SMOG as of December 31 is as follows:

Certain information concerning the assumptions used in computing SMOG and their inherent limitations are
discussed below. We believe this information is essential for a proper understanding and assessment of the data presented.

The assumptions used to compute SMOG do not necessarily reflect our expectations of actual revenues to be derived from those reserves nor their present worth. Assigning monetary values to the reserve quantity estimation process does not
reduce the subjective and ever-changing nature of reserve estimates. Additional subjectivity occurs when determining present values because the rate of producing the reserves must be estimated. In addition to difficulty inherent in predicting the
future, variations from the expected production rate could result from factors outside of our control, such as unintentional delays in development, environmental concerns or changes in prices or regulatory controls. Also, the reserve valuation
assumes that all reserves will be disposed of by production. However, other factors such as the sale of reserves in place could affect the amount of cash eventually realized.

Effective December 31, 2009, future cash flows are computed by applying the unescalated 12-month average prices of $61.18 per barrel
for oil, $34.44 per barrel for NGLs and $3.86 per Mcf for natural gas relating to proved reserves and to the year-end quantities of those reserves. Previously, the price was based on the single-day period-end price. Future price changes are
considered only to the extent provided by contractual arrangements in existence at year-end.

Future production and
development costs are computed by estimating the expenditures to be incurred in developing and producing the proved oil, NGLs and natural gas reserves at the end of the year, based on continuation of existing economic conditions.

UNIT CORPORATION AND SUBSIDIARIES

SUPPLEMENTAL OIL AND GAS DISCLOSURES(Continued)

(UNAUDITED)



Future income tax expenses are computed by applying the appropriate year-end statutory
tax rates to the future pretax net cash flows relating to proved oil, NGLs and natural gas reserves less the tax basis of our properties. The future income tax expenses also give effect to permanent differences and tax credits and allowances
relating to our proved oil, NGLs and natural gas reserves.

Care should be exercised in the use and interpretation of the
above data. As production occurs over the next several years, the results shown may be significantly different as changes in production performance, petroleum prices and costs are likely to occur.

| | (a) | Evaluation of Disclosure Controls and Procedures
| | --- | ------------------------------------------------

The company maintains disclosure controls and procedures, as that term is defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities Exchange Act of 1934 (the Exchange Act), that are
designed to ensure that information required to be disclosed in reports the company files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that such
information is collected and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating its disclosure controls
and procedures, our management recognized that no matter how well conceived and operated, disclosure controls and procedures can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met.
Our disclosure controls and procedures have been designed to meet, and our management believes that they meet, reasonable assurance standards. Based on their evaluation as of the end of the period covered by this Annual Report on Form 10-K, our
Chief Executive Officer and Chief Financial Officer have concluded that, subject to the limitations noted above, the companys disclosure controls and procedures were effective.



| | (b) | Managements Report on Internal Control Over Financial Reporting
| | --- | ----------------------------------------------------------------

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as that is defined in Exchange Act Rule 13a-15(f). Our management, including our Chief
Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of our internal control over financial reporting based on the Internal ControlIntegrated Frameworkissued by the Committee of Sponsoring
Organizations of the Treadway Commission. Based on the results of this evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2009.

The effectiveness of the companys internal control over financial reporting as of December 31, 2009, has been audited by
PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.



| | (c) | Changes in Internal Control Over Financial Reporting
| | --- | ----------------------------------------------------

During the last quarter, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over
financial reporting.

his annual certification to that effect to the NYSE as of May 18, 2009. In addition, we have filed, as exhibits to this Annual Report on Form 10-K, the certifications of our Chief Executive Officer and Chief Financial Officer required under
