PART I



|Item 1. | Business
|------- | --------

We provide contract land
drilling services and equipment, primarily to natural gas producers in the United States. In addition to our drilling rigs, we provide the drilling crews and most of the ancillary equipment needed to operate our drilling rigs. We commenced
operations in 1997 with 12 drilling rigs and related equipment acquired from an entity providing contract drilling services under the name Union Drilling. Through a combination of acquisitions and new rig construction, we currently
operate a fleet of 71 marketed land drilling rigs. We presently focus our operations in selected natural gas production regions in the United States. We do not invest in oil and natural gas properties. The drilling activity of our customers is
highly dependent on many factors, including the market price of oil and natural gas, available capital, available drilling prospects, support services and market availability. These factors should not be considered an exhaustive list. See
Item 1A. Risk Factors.

Substantially all of our rigs operate in unconventional natural gas producing areas, which are
characterized by formations with very low permeability rock, such as shales, tight sands and coal bed methane, or CBM, that require specialized drilling techniques to efficiently develop the natural gas resources. Horizontal drilling is often used
in these formations to increase the exposure of the wellbore to the natural gas producing formation and increase drainage rates and production volumes. We have equipped 53 of our 71 rigs for drilling horizontal wells. As many of these areas are also
characterized by hard rock formations entailing more difficult drilling conditions, we have equipped 50 of our 71 rigs with compressed air circulation systems, also known as underbalanced drilling, which provides higher penetration rates through
hard rock formations when compared to traditional fluid-based circulation systems. We are also in the process of outfitting seven of our 71 rigs with walking or skidding systems which allow for multiple wells to be drilled in a single location to
provide efficiency and to reduce the overall environmental impact. Moreover, we continue to enhance our fleet of drilling rigs with technological capabilities through upgrades, acquisitions or new rig construction in order to improve drilling
productivity and reduce total well costs for our customers.

Our market

We provide drilling services to customers primarily engaged in developing unconventional natural gas formations throughout the United States. Our strategy is to focus our operations in the major U.S.
shale formations, with high growth potential, low finding and development costs, and adequate takeaway capacity. Our principal operations are in the Appalachian Basin, extending from New York to Tennessee including the Marcellus and Huron shales, as
well as the Clinton and Medina sands; the Arkoma Basin in eastern Oklahoma and Arkansas, including the Fayetteville and Caney shales; and the Fort Worth Basin in Northern Texas, including the Barnett Shale and Permian Basin.

Customers

We market our rigs to a number
of customers, who are principally independent natural gas producers. Repeat business from customers accounts for a substantial portion of our business. In 2009, 2008 and 2007, we performed services for 64, 121 and 114 customers, respectively. In
2009, 2008 and 2007, our top 20 customers provided 89%, 71% and 76%, respectively, of our total revenue. The following table shows our three largest customers as a percentage of our total contract drilling revenue for each of our last three years.

Drilling contracts

We enter into written contracts with our customers for all rig deployments. The length of contracts has ranged from very short term, for example, a one-well project, to much longer term for major exploration programs. Our contracts for
drilling natural gas wells are obtained either through competitive bidding or through direct negotiations with customers. Our oil and natural gas drilling contracts provide for compensation on a daywork (fixed rate per day is charged) or footage
(fixed rate per foot of hole drilled to a stated depth) basis. Contracts performed on a footage basis involve greater risk to the contractor than do contracts performed on a daywork basis. In 2009 and 2008, approximately 96% and 90%, respectively,
of our revenues were derived from daywork contracts. Contract terms we offer generally depend on the complexity and risk of operations, the on-site drilling conditions, the type of equipment used and the anticipated duration of the work to be
performed. Our contracts generally provide for the drilling of a single well or a series of wells and typically permit the customer to terminate on short notice. In most instances, our contacts provide for additional payments related to rig
mobilization and demobilization, as well as reimbursement of certain out-of-pocket costs.

As of December 31, 2009, we had 18 rigs under
term contracts, which we define as a contract for drilling services with an original term in excess of six months. In some cases, a contract may be extended beyond the original term at prices mutually agreeable to us and the customer.

Our rig fleet

A land drilling rig consists
of a derrick, a substructure, a hoisting system, a rotating system, pumps and holding tanks to circulate and clean drilling fluid, blowout preventers and other related equipment. Diesel engines are typically the main power sources for a drilling
rig. There are numerous factors that differentiate land drilling rigs, including their power generation systems and their drilling depth capabilities. The actual drilling depth capability of a rig may be more or less than its rated depth capability
due to numerous factors, including the size, weight and amount of the drill pipe on the rig. The intended well depth and the drill site conditions determine the amount of drill pipe and other equipment needed to drill a well. Generally, land rigs
operate with crews of four to six persons.

Derrick hookload capacity and rig horsepower are the main drivers of depth rating on a vertical
rig. They determine a rigs ability to lower, hoist and suspend casing and drilling pipe weight in the wellbore. Relative to total measured depth, horizontal wells have lower requirements on hookload and horsepower because casing, which is used
to isolate the natural gas bearing formation from other geological features, is not run into the horizontal section of the well and once drill pipe is laying horizontally, its suspended weight and the power required to raise it decreases compared to
a vertical wellbore of the same length. Circulating systems, which can be based on either fluid or compressed air, are used while drilling to evacuate cuttings and prevent the pipe from becoming stuck in the wellbore. Relative to vertical wells of
the same measured depth, horizontal wells require greater circulating capability to move the cuttings from the horizontal section through a 90 degree curve to the initial vertical section of the wellbore.

The size and type of rig utilized depends, among other factors, upon well depth and site conditions. An
active maintenance and replacement program during the life of a drilling rig permits upgrading of components on an individual basis. Over the life of a typical rig, due to the normal wear and tear of operating up to 24 hours a day, several of the
major components, such as engines, air compressors, boosters and drill pipe, are replaced or rebuilt on a periodic basis as required. Other components, such as the substructure, mast and drawworks, can be utilized for extended periods of time with
proper maintenance.

Our drilling rigs have engines that power the hoisting and rotating systems rated from 400 to 1,600 horsepower and
derricks with weight suspension capacities from 110,000 to 750,000 pounds. Most of our rigs that are equipped for horizontal drilling have a pair of circulating pumps, each powered by engines that vary from 500 to 1,600 horsepower and our rigs that
are capable of underbalanced drilling have two to four air compressors and one to two compression boosters, each with engines of 450 to 750 horsepower. Twenty-three of our rigs also have top drive units that separate the power and control of the
hoisting and rotating functions, which often provides better performance in horizontal drilling. Many larger drilling rigs capable of drilling in deep formations generate electricity from diesel engines and power electric motors attached to the
equipment in the hoisting, rotating and circulating systems. We have ten rigs of this design.

Due to the geologic characteristics in the
Appalachian and Arkoma Basins, many of the wells drilled in these areas utilize underbalanced or air drilling. We believe that air drilling provides advantages over traditional fluid drilling techniques when drilling through hard rock formations.
These advantages include improved drilling penetration rates, no fluid loss into the formation and minimized formation damage. We believe that we are one of the most experienced U.S. contractors using air drilling techniques.

We are in the process of outfitting seven of our rigs with either walking or skidding systems that allow for pad drilling, or drilling of multiple wellheads
on one surface location in order to reduce the environmental impact of drilling because less surface area is disturbed, provide for less wear to our rig equipment and less time relocating the rig, all of which make it more efficient and less
expensive to complete and produce the wells for our customers.

We believe that our drilling rigs and other related equipment are in good
operating condition. Our employees perform periodic maintenance and repair work on our drilling rigs. We rely on various oilfield service companies for major repair work and overhaul of our drilling equipment when needed. We also engage in periodic
improvement of our drilling equipment. In the event of major breakdowns or mechanical problems, our rigs could be subject to significant idle time and a resulting loss of revenue if the necessary repair services are not immediately available.

We also own a fleet of trucks that are used to move our rigs as well as bulldozers, forklifts, various vehicles and other equipment that is
used to support the operation of our rigs.

The following table sets forth certain information regarding each of our marketed rigs as of
February 26, 2010:

Competition

We encounter substantial competition from other land drilling contractors. The fact that drilling rigs are mobile and can be moved from one region to another
in response to market conditions heightens the competition in the industry. Our principal competitors include smaller, family-owned companies as well as larger privately held drilling companies and publicly traded drilling companies. No single
drilling company dominates within our regions. We believe rig capability, pricing and rig availability are the primary factors our potential customers consider in determining which drilling contractor to select. In addition, we believe the following
factors are important:



| |  |  | the mobility and efficiency of the rigs;
| | - |  | ----------------------------------------



| |  |  | the safety records of the rigs;
| | - |  | -------------------------------



| |  |  | crew experience and skill;
| | - |  | --------------------------



| |  |  | customer relationships;
| | - |  | -----------------------



| |  |  | the offering of ancillary services; and
| | - |  | ---------------------------------------



| |  |  | the ability to provide drilling equipment adaptable to, and personnel familiar with, current technologies and drilling techniques.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------

While we must be competitive in our pricing, our strategy generally emphasizes the quality of our equipment, the safety
record of our rigs and the experience of our rig crews to differentiate us from our competitors.

Raw materials

The materials and supplies we use in our drilling operations include fuels to operate our drilling equipment, drill pipe and drill collars. We do not rely on
a single source of supply for any of these items.

Seasonality

Certain of our operations in the Appalachian Basin are conducted in areas subject to extreme weather conditions and often in difficult terrain. During certain parts of the year, primarily in the winter
and the spring, our operations are often hindered because of cold, snow or muddy conditions. Certain state and local governments impose restrictions on the movement of our equipment during parts of the year when the roads are susceptible to damage
from the movement of heavy equipment. These restrictions are known as frost laws. Our operations can be limited from time to time by the difficulty of operating in certain weather conditions.

In the southern Appalachian Basin, our operations are limited primarily by winter weather in the fourth quarter and the first quarter. In the northern
Appalachian Basin, our operations are limited primarily by the frost laws in the first quarter and the second quarter.

Employees

As of February 26, 2010, we had approximately 1,000 employees. The number of employees fluctuates depending on the number of drilling
projects we are engaged in at any particular time. None of our employment arrangements is subject to collective bargaining arrangements.

Government regulation and environmental matters

General

Many aspects of our operations are
subject to federal, state and local, environmental, health and safety laws and regulations. We do not anticipate any material capital expenditures for environmental control facilities or extraordinary expenditures to comply with environmental rules
and regulations in the foreseeable future. However, compliance costs under existing laws or under any new requirements could become material, and we could incur liability in any instance of noncompliance.

Environmental regulation

Our activities
are subject to federal, state and local laws and regulations governing environmental quality, pollution control and the preservation of natural resources (including global climate change). These laws and regulations concern, among other things, air
emissions, water use and disposal, the containment, disposal and recycling of waste materials, and reporting of the storage, use or release of certain chemicals or hazardous substances. Numerous federal and state environmental laws regulate drilling
activities and impose liability for discharges of waste or spills, including those in coastal areas.

Except for the handling of waste
directly generated from the operation and maintenance of our drilling rigs, such as waste oils and wash water, it is our practice, to the greatest extent practicable, to require our customers to contractually assume responsibility for compliance
with environmental regulations. Laws and regulations protecting the environment have become more stringent in recent years, and may, in some circumstances, impose strict liability, rendering a person liable for environmental damage without regard to
negligence or fault on the part of that person. These laws and regulations may expose us to liability for the conduct of or conditions caused by others, or for our own acts that were in compliance with all applicable laws at the time the acts were
performed. The application of these requirements or adoption of new requirements could have a material adverse effect on us.

Environmental
regulations that affect our customers also have an indirect impact on us. Increasingly stringent environmental regulation of the oil and natural gas industry has led to higher drilling costs and a more difficult and lengthy well permitting process.
The primary environmental statutory and regulatory programs that affect our operations include The Oil Pollution Act of 1990 (OPA), and the Comprehensive Environmental Response, Compensation, and Liability Act, as amended (CERCLA). OPA pertains to
the prevention of and response to spills or discharges of hazardous substances or oil into navigable waters. We have incurred no liability under OPA. CERCLA imposes liability, without regard to fault or the legality of the original conduct, on
certain classes of persons with respect to the release of a hazardous substance into the environment. To date, we have not been named as a potentially responsible party under CERCLA.

Hazardous waste disposal

Our operations
involve the generation or handling of materials that may be classified as hazardous waste and subject to various federal laws and comparable state statutes. The EPA and various state agencies have limited the disposal options for some hazardous and
nonhazardous wastes. We believe that our operations are in compliance with applicable environmental laws and regulations.

Health and
safety matters

Our facilities and operations are also subject to the requirements of the federal Occupational Safety and Health Act, or
OSHA, as well as comparable state and local laws that regulate the protection of worker health and safety. In addition, the OSHA hazard communication standard requires that we maintain certain information about any hazardous materials used or
produced in our operations and that this information be provided to employees, state and local government authorities and citizens. We believe that our operations are in material compliance with OSHA requirements, including general industry
standards, record keeping requirements and monitoring of occupational exposure to regulated substances.

Trucking regulations

We operate a fleet of trucks to transport our drilling rigs and related equipment. We operate as a private motor carrier, not as a
common carrier for hire. We are licensed to perform both intrastate and interstate trucking

operations. As a private motor carrier we are subject to certain safety regulations issued by the U.S. Department of Transportation, or DOT, and comparable state regulatory
agencies. These trucking regulations cover, among other things, driver operations, maintaining log books, truck manifest preparations, the placement of safety placards on our regulated trucks and trailers, driver drug and alcohol testing,
safety of operation and equipment, and several other aspects of truck operations. Our trucking operations are also subject to certain OSHA requirements when our employees are loading or unloading equipment at a drilling site. We believe our
trucking operations are in material compliance with applicable regulations.

Risks Relating to Our
Business

We operate in a highly competitive industry with excess drilling capacity which can adversely affect our results of
operations and access to our revolving credit facility.

The contract land drilling services industry in which we operate is very
competitive. Further, drilling rigs are mobile and can be moved from one region to another in response to market conditions, which heightens the competition in the industry. Over the last few years, there has been a substantial increase in the
supply of land drilling rigs, whether through new construction or refurbishment, while the demand for such rigs over the last year has dramatically decreased due to volatile natural gas prices. In recent months, while there has been an increase in
drilling activities, it has been limited to certain shale plays and dominated by higher performance rigs. As a result, there is currently excess capacity in certain geographic markets in which we operate with the number of drilling rigs available
for use exceeding the demand for rigs. Excess capacity and price competition can negatively impact our revenue rates, utilization and profitability, as well as the value of our rig equipment, which could result in write-downs of our asset carrying
values. The availability of our revolving credit facility is based, in part, on the value of our rig equipment, and if there are significant declines in the value of such equipment, access to our revolving credit facility could be reduced.

A weak global economy may affect the Companys business.

As a result of recent volatility in oil and natural gas prices and lingering uncertainty of when the global economic environment will begin a sustained recovery, the Company is unable to accurately
predict the extent to which its customers will spend on exploration and development drilling or whether customers and /or vendors and suppliers will be able to access financing necessary to sustain or increase their current level of operations,
fulfill their commitments and/or fund future operations and obligations. Furthermore, the Company is unable to predict the extent its existing customers will have continuing viability and capability to pay amounts owed to the Company. The weak
global economic environment continues to impact industry fundamentals, and the resulting decrease in demand for drilling rigs could cause the drilling industry to remain in a contracted state. These conditions could have a material adverse effect on
the Companys business, including reductions in our revenues and impairments of our rig fleet.

##### Table of Contents

Our business and operations are substantially dependent upon, and affected by, the level of U.S.
land-based natural gas exploration and development activity, which has experienced significant volatility. If the level of that activity remains depressed, our business and results of operations could be adversely affected.

Our business and operations are substantially dependent upon, and affected by, the level of U.S. land-based natural gas exploration and development
activity. Exploration and development activity determines the demand for contract land drilling and related services. We have no control over the factors driving the level of U.S. natural gas exploration and development activity. If the level of
that activity remains depressed, our business and results of operations could be adversely affected. Other factors include, among others, the following:



| |  |  | the market prices of natural gas;
| | - |  | ---------------------------------



| |  |  | market expectations about future prices of natural gas or oil (which is closely correlated with natural gas prices);
| | - |  | --------------------------------------------------------------------------------------------------------------------



| |  |  | the cost of producing and delivering natural gas;
| | - |  | -------------------------------------------------



| |  |  | the capacity of the natural gas pipeline network;
| | - |  | -------------------------------------------------



| |  |  | government regulations and trade restrictions;
| | - |  | ----------------------------------------------



| |  |  | the presence or absence of tax incentives;
| | - |  | ------------------------------------------



| |  |  | national and international political and economic conditions;
| | - |  | -------------------------------------------------------------



| |  |  | levels of production by, and other activities of, the Organization of Petroleum Exporting Countries and other oil and natural gas producers;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the levels of imports of natural gas, whether by pipelines from Canada or Mexico or by tankers in the form of LNG; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | the development of alternate energy sources and the long-term effects of worldwide energy conservation measures.
| | - |  | ----------------------------------------------------------------------------------------------------------------

The land-based contract drilling industry has experienced significant volatility in profitability and asset values. The industrys most recent
significant downturn began in the second half of 2008 and declined rapidly in the first half of 2009. Management is unable to predict at the present time the extent or longevity of this market decline. The major causes of the industry downturn were
generated by a significant widespread global economic downturn and credit restrictions. This economic downturn, driven by decreasing demand, has generated lower natural gas prices and, in turn, has reduced many of our customers capital
expenditures as well as their ability to finance their commitments. We cannot predict the future level of demand for, or pricing of, natural gas, for our contract drilling services or overall future conditions in the land-based contract drilling
industry. We have experienced a decline in our rig utilization, and continue to receive requests from customers for pricing considerations. We actively monitor, evaluate, and implement changes to meet these changing conditions. We have
laid off workers, deferred capital expenditure to future periods and reduced costs.

Term contracts may in certain instances be
terminated without an early termination payment.

Term drilling contracts customarily provide for termination at the election of the
customer, with an early termination payment to be paid to the Company if a contract is terminated prior to the expiration of the term. However, under certain limited circumstances, such as destruction of a drilling rig, limited capital
resources of the customer or bankruptcy of the customer, no early termination payment may be paid to the Company or, if paid, not paid in a timely manner. Even if an early termination payment is owed to the Company, the continuing weak economy may
affect the customers ability to timely pay (or pay at all) the early termination payment.

In the year ended December 31,
2009, we derived approximately 55% of our total revenues from three customers. The loss of any of those customers or the failure to remarket the rigs employed by those customers could have a material adverse effect on our financial condition and
results of operations.

In the year ended December 31, 2009, our three largest customers accounted for approximately 28%, 16% and
11%, respectively, of our total revenues. Our principal customers may not continue to employ our services and we may not be able to successfully remarket the rigs. The loss of any of our principal customers or the failure to remarket the rigs
utilized by those customers could have a material adverse effect on our financial condition and results of operations.

Increased demand among drilling contractors for consumable supplies, including fuel, and ancillary rig
equipment, such as pumps, valves, drillpipe and engines, may lead to delays in obtaining these materials and our inability to operate our rigs in an efficient manner.

Most of our contracts provide that our customers bear the financial impact of increased fuel prices. However, prolonged shortages in the availability of fuel to run our drilling rigs resulting from action
of the elements, warlike actions or other Force Majeure events could result in the suspension of our contracts and have a material adverse effect on our financial condition and results of operations. We have periodically experienced
increased lead times in purchasing ancillary equipment for our drilling rigs. To the extent there are significant delays in being able to purchase important components for our rigs, certain of our rigs may not be available for operation or may not
be able to operate as efficiently as expected, which could adversely affect our financial condition, results of operations and cash flows.

Decreased demand among drilling contractors for consumable supplies, including fuel, and ancillary rig equipment, such as pumps, valves, drillpipe and engines, may lead to future delays in obtaining these materials and our inability
to operate our rigs in an efficient manner.

Reduced demand can drive suppliers from the market. With reduced suppliers, consumables
for our operations may not be readily available. Additionally, suppliers may experience shortfalls in obtaining their materials and/or labor. Suppliers who have been regular providers to us may experience shortfalls and that may lead to delays as we
secure other sources.

To the extent we acquire additional rigs in the future, we may experience difficulty integrating those
acquisitions. Additionally, we may incur leverage to effect those acquisitions, which adds additional financial risk to our business. To the extent we incur additional leverage in financing acquisitions, it may adversely affect our financial
position.

The process of integrating acquired rigs or newly constructed rigs may involve unforeseen difficulties and may require a
disproportionate amount of managements attention and other resources. We may not be able to successfully manage and integrate new rigs into our existing operations or successfully maintain the market share attributable to drilling rigs that we
purchase. We also may encounter cost overruns related to newly constructed rigs or unexpected costs related to acquired rigs, including costs associated with major overhauls. To the extent we experience some or all of these difficulties, our
financial condition would be adversely affected.

Expanding our fleet by building new rigs or acquiring rigs from third parties may cause the
company to incur additional financial leverage, increasing our financial risk, and debt service requirements, which could adversely affect our operating results and financial position.

We may decide to purchase or internally build additional drilling rigs and upgrade or refurbish some of our marketed drilling rigs. Any delay could result in a loss of revenue.

We may purchase or internally build additional drilling rigs and upgrade or refurbish some of our current drilling rigs. All of these projects are
subject to risks of delay or cost overruns inherent in large construction projects. Among those risks are:



| |  |  | shortages of equipment, materials or skilled labor;
| | - |  | ---------------------------------------------------



| |  |  | long lead times or delays in the delivery of ordered materials and equipment;
| | - |  | -----------------------------------------------------------------------------



| |  |  | engineering problems;
| | - |  | ---------------------



| |  |  | work stoppages;
| | - |  | ---------------



| |  |  | weather interference;
| | - |  | ---------------------



| |  |  | availability of specialized services; and
| | - |  | -----------------------------------------



| |  |  | cost increases.
| | - |  | ---------------

These
factors may contribute to delays in the delivery, upgrade or completion of the refurbishment of the drilling rigs, which could result in a loss of revenue. Additionally, we may incur higher costs than expected, which would adversely affect the
economics of the investment in such rigs.

We may not be able to raise additional funds through public or private financings or additional
borrowings, which could have a material adverse effect on our financial condition.

The contract drilling industry is capital
intensive. Our cash flow from operations and the continued availability of credit are subject to a number of variables, including general economic conditions, and more specifically, our rig utilization rates, operating margins and ability to control
costs and obtain contracts in a competitive industry. Our cash flow from operations and present borrowing capacity may not be sufficient to fund our anticipated acquisition program, capital expenditures and working capital requirements. We may from
time to time seek additional financing, either in the form of bank borrowings, sales of debt or equity securities or otherwise. To the extent our capital resources and cash flow from operations are at any time insufficient to fund our activities or
repay our indebtedness as it becomes due, we will need to raise additional funds through public or private financings or additional borrowings. We may not be able to obtain any such capital resources in the amount or at the time when needed. If we
are at any time not able to obtain the necessary capital resources, our financial condition and results of operations could be materially adversely affected.

We could be adversely affected if we lost the services of certain of our officers and key employees.

The success of our business is highly dependent upon the services, efforts and abilities of certain key employees, such as our regional managers and of Christopher D. Strong, our President and Chief
Executive Officer and David S. Goldberg, our General Counsel. Our business could be materially and adversely affected by the loss of any of these individuals. We have limited employment agreements with some key employees. We do not maintain key man
life insurance on the lives of any of our executive officers.

If we cannot keep our rigs utilized at profitable rates, our operating
results could be adversely affected.

Our business has high fixed costs, and if we cannot keep our rigs utilized at profitable rates,
our operating results could be adversely affected through reductions in our revenues and impairments of our rig fleet.

Our operations
could be adversely affected by abnormally poor weather conditions.

Our operations are conducted in areas subject to extreme weather
conditions, and often in difficult terrain. Primarily in the winter and spring, our operations are often curtailed because of cold, snow or muddy conditions. Unusually severe weather conditions could further curtail our operations and could have a
material adverse effect on our financial condition and results of operations.

We have limited control over the timing of payment of our
deferred tax liabilities.

We currently have deferred tax liabilities and have limited control over the timing of the payment of these
deferrals. These deferred liabilities could come due at a time when our revenues are reduced. This could cause tax payments to be due at a time when our cash flow from operations is reduced. Such a situation could have a material adverse effect on
our financial condition.

Increased competition in our drilling markets could adversely affect rates and utilization of our rigs, which
could adversely affect our financial condition and results of operations.

We face competition from significantly larger domestic and
international drilling contractors, many with greater resources. Their greater resources may enable them to allocate those resources into any of our regional markets. The additional competition in our markets, either by existing competitors or new
entrants would increase the supply in those markets, which could adversely affect the rates we can charge and utilization levels we can achieve.

Our operations are subject to hazards inherent in the land drilling business beyond our control. If those risks are not adequately insured or indemnified against, our results of operations could be adversely affected.

Our operations are subject to many hazards inherent in the land drilling business, including, but not limited to:



| |  |  | blowouts;
| | - |  | ---------



| |  |  | craterings;
| | - |  | -----------



| |  |  | fires;

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



| |  |  | damage or loss from inclement weather or natural disasters.
| | - |  | -----------------------------------------------------------

These hazards are to some extent beyond our control and could cause, among other things:



| |  |  | personal injury or death;
| | - |  | -------------------------



| |  |  | serious damage to or destruction of property and equipment;
| | - |  | -----------------------------------------------------------



| |  |  | suspension of drilling operations; and
| | - |  | --------------------------------------



| |  |  | substantial damage to the environment, including damage to producing formations and surrounding areas.
| | - |  | ------------------------------------------------------------------------------------------------------

Our insurance policies for public liability and property damage to others and injury or death to persons are in some cases subject to large deductibles and
may not be sufficient to protect us against liability for all consequences of well disasters, personal injury, extensive fire damage or damage to the environment. We may not be able to maintain adequate insurance in the future at rates we consider
reasonable, or particular types of coverage may not be available. The occurrence of events, including any of the above-mentioned risks and hazards, that are not fully insured against or the failure of a customer that has agreed to indemnify us
against certain liabilities to meet its indemnification obligations could subject us to significant liability and could have a material adverse effect on our financial condition and results of operations. There is no guarantee that our insurance
carriers will be able to perform at the time their performance is due.

Our operations are subject to environmental, health and safety
laws and regulations that may expose us to liabilities for noncompliance, which could adversely affect us.

The U.S. oil and natural
gas industry is affected from time to time in varying degrees by political developments and federal, state and local environmental, health and safety laws and regulations applicable to our business. Our operations are vulnerable to certain risks
arising from the numerous environmental health and safety laws and regulations. These laws and regulations may restrict the types, quantities and concentration of various substances that can be released into the environment in connection with
drilling activities, require reporting of the storage, use or release of certain chemicals and hazardous substances, require removal or cleanup of contamination under certain circumstances, and impose substantial civil liabilities or criminal
penalties for violations. Environmental laws and regulations may impose strict liability, rendering a company liable for environmental damage without regard to negligence or fault, and could expose us to liability for the conduct of, or conditions
caused by, others, or for our acts that were in compliance with all applicable laws at the time such acts were performed. Moreover, there has been a trend in recent years toward stricter standards in environmental, health and safety legislation and
regulation, which may continue. While the scientific debate concerning the impact of human activities on world climate change continues, we recognize the need to minimize in a commercially reasonable manner our impact on the environment, including
the release of greenhouse gases.

We may incur material liability related to our operations under governmental regulations, including
environmental, health and safety requirements. We cannot predict how existing laws and regulations may be interpreted by enforcement agencies or court rulings, whether additional laws and regulations will be adopted, or the effect such changes may
have on our business, financial condition or results of operations. Because the requirements imposed by such laws and regulations are subject to change, we are unable to forecast the ultimate cost of compliance with such requirements. The
modification of existing laws and regulations or the adoption of new laws or regulations, both in the U.S. and globally, which directly or indirectly curtail exploratory or development drilling for oil and natural gas for economic, political,
environmental or other reasons could have a material adverse effect on us by limiting drilling opportunities.

Our debt agreements
contain restrictions that limit our flexibility in operating our business.

Our revolving credit facility contains various provisions
that limit our ability to engage in specified types of transactions. These provisions limit our ability to, among other things:



| |  |  | incur additional indebtedness;
| | - |  | ------------------------------



| |  |  | issue certain preferred shares;
| | - |  | -------------------------------

Risks Related to Our Common Stock

Our principal stockholder has significant ownership.

As of February 26, 2010, Union Drilling Company LLC, our
principal stockholder, owned approximately 34% of our outstanding common stock. As a result, Union Drilling Company LLC and its affiliates may substantially influence the outcome of stockholder votes, including votes concerning the election of
directors, the adoption or amendment of provisions in our certificate of incorporation or bylaws and the approval of mergers and other significant corporate transactions. The existence of this level of ownership concentration makes it less likely
that any small holder of our common stock will be able to affect the management or direction of Union Drilling. These factors may also have the effect of delaying or preventing a change in the management or voting control of Union Drilling.

Provisions in our certificate of incorporation and bylaws as well as Delaware corporate law may make a takeover difficult.

Provisions in our certificate of incorporation and bylaws, as well as Delaware corporate law, may make it difficult and expensive for a third
party to pursue a tender offer, change in control or takeover attempt that is opposed by our management and, or our board of directors. These anti-takeover provisions could substantially impede the ability of public stockholders to benefit from a
change in control or change our management and board of directors.

We do not intend to pay cash dividends on our common stock in the
foreseeable future, and therefore only appreciation of the price of our common stock, which may not occur, will provide a return to our stockholders.

We currently anticipate that we will retain all future earnings, if any, to finance growth and development of our business. We do not intend to pay cash dividends in the foreseeable future. Any payment of
cash dividends will depend upon our financial condition, capital requirements, earnings and other factors deemed relevant by our board of directors. In addition, the terms of our revolving credit facility restrict us from paying dividends and making
other distributions unless certain conditions are satisfied. As a result, presently only appreciation of the price of our common stock, which may not occur, will provide a return to our stockholders.

Trading volume of our common stock may contribute to its price volatility.

Our common stock is traded on the NASDAQ Global Select Market. During the period from January 1, 2009 through February 26, 2010, the average daily trading volume of our common stock as
reported by the NASDAQ Global Select Market was 80,563 shares. There can be no assurance that a more or less active trading market in our common stock will develop. As a result, relatively small or large trades may have a disproportionate
impact on the price of our common stock and, therefore, may contribute to the price volatility of our common stock. As a result, our common stock may be subject to greater price volatility than the stock market when taken as a whole, or
comparable securities of other contract drilling service providers, who may or may not have greater volumes.

The market price of our common
stock has been, and may continue to be, volatile. During the period from January 1, 2009 through February 26, 2010, the trading price of our common stock ranged from $2.51 to $10.25 per share. Because of the limited trading market of
our common stock and the price volatility of our common stock, you may be unable to fully sell shares of our common stock when you desire or at a price you desire.

Purchases of Equity Securities

In August 2008, the Companys Board approved the 2008 Union Drilling, Inc. Share Repurchase Program (the Program). Under the Program, the Board authorized the Company to repurchase
up to two million shares of the Companys outstanding common stock. The authorization under the Program did not have a stated expiration date and the pace of repurchase activity was dependant on factors such as levels of cash generation
from operations, cash requirements for asset acquisitions or other capital expenditures, debt repayment and the Companys current stock price, among other factors. The table below sets forth share repurchase information for the time periods
indicated.

EBITDA is earnings before net interest, income taxes, depreciation and
amortization and non-cash impairment. The Company believes EBITDA is a useful measure of evaluating its financial performance because it is used by external users, such as investors, commercial banks, research analysts and others, to assess:
(1) the financial performance of Union Drillings assets without regard to financing methods, capital structure or historical cost basis, (2) the ability of Union Drillings assets to generate cash sufficient to pay interest
costs and support its indebtedness, and (3) Union Drillings operating performance and return on capital as compared to those of other entities in our industry, without regard to financing or capital structure. EBITDA is not a measure of
financial performance under generally accepted accounting principles. However, EBITDA is a common alternative measure of operating performance used by investors, financial analysts and rating agencies. A reconciliation of EBITDA to net (loss) income
is included above. EBITDA as presented may not be comparable to other similarly titled measures reported by other companies.

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

This managements discussion and analysis of financial condition and results of operations (MD&A) section of our Annual Report on
Form 10-K discusses our results of operations, liquidity and capital resources, and certain factors that may affect our future results, including economic and industry-wide factors. You should read this MD&A in conjunction with our financial
statements and accompanying notes included under Part II, Item 8, of this Annual Report.

Statements we make in the following
MD&A discussion and in other parts of this report that express a belief, expectation or intention, as well as those which are not historical fact, are forward-looking statements within the meaning of the federal securities laws and are subject
to risks, uncertainties and assumptions. These forward-looking statements may be identified by the use of words such as expect, anticipate, believe, estimate, potential or similar
words. These matters include statements concerning managements plans and objectives relating to our operations or economic performance and related assumptions, including general economic and business conditions and industry trends, the
continued strength or weakness of the contract land drilling industry in the geographic areas in which we operate, decisions about onshore exploration and development projects to be made by oil and gas companies, the highly competitive nature of our
business, our future financial performance, including availability, terms and deployment of capital, the continued availability of qualified personnel, and changes in, or our failure or inability to comply with, government regulations, including
those relating to workplace safety and the environment. Although we believe that the expectations reflected in these forward-looking statements are reasonable, we can give no assurance that such expectations will prove to have been correct. Further,
we specifically disclaim any duty to update any of the information set forth in this report, including any forward-looking statements. Forward-looking statements are made based on managements current expectations and beliefs concerning future
events and, therefore, involve a number of assumptions, risks and uncertainties, including the risk factors described in Item 1A, Risk Factors, above. Management cautions that forward-looking statements are not guarantees, and our
actual results could differ materially from those expressed or implied in the forward-looking statements.

Company Overview

Union Drilling, Inc. provides contract land drilling services and equipment, primarily to natural gas producers. In addition to our
drilling rigs, we provide the drilling crews and most of the ancillary equipment needed to operate our drilling rigs. We commenced operations in 1997 with 12 drilling rigs and related equipment acquired from an entity providing contract drilling
services under the name Union Drilling. Through a combination of acquisitions and new rig construction, we have increased the size of our fleet to 71 marketed land drilling rigs. We presently focus our operations in selected natural
gas production regions in the United States, primarily the Fort Worth Basin in North Texas, the Arkoma Basin in Oklahoma and Arkansas and throughout the Appalachian Basin. We do not invest in oil and natural gas properties.

We completed several transactions from 2005 through 2009 which increased the size of our rig fleet, thus enhancing our ability to serve our customers. Two
acquisitions in 2005 provided us with unconventional natural gas contract drilling operations in North Texas and the Arkoma Basin. We subsequently purchased additional rigs, including newly-constructed rigs, and have devoted significant capital
expenditures to upgrade other rigs in our fleet for unconventional drilling. Contractual commitments were obtained from our customers in recent years to substantiate these rig purchases and significant rig upgrades. At various times, we remove rigs
from our marketed fleet, and the components are made available for use on other rigs. We are also in the process of outfitting seven of our 71 rigs with walking or skidding systems which allow for multiple wells to be drilled in a single
location to provide efficiency and to reduce the overall environmental impact. Moreover, we continue to enhance our fleet of drilling rigs with technological capabilities through upgrades, acquisitions or new rig construction in order to improve
drilling productivity and reduce total well costs for our customers.

Key Indicators of Financial Performance for Management

Key performance measurements in our industry are rig utilization, revenue per revenue day and operating expenses per revenue
day. Revenue days for each rig are days when the rig is earning revenues under a contract, which is usually a period from the date the rig begins moving to the drilling location until the rig is released from the contract. We compute rig
utilization rates by dividing revenue days by total available days during a period. Total available days are the number of calendar days during the period that we have owned the marketed rig.

|                                   |  |                          |        |   |      |   |        |      |  |   |        |  
|---------------------------------- |  | ------------------------ | ------ | - | ---- | - | ------ | ---- |  | - | ------ | -
|                                   |  | Years Ended December 31, |       
|                                   |  | 2009                     |        |   | 2008 |   |        | 2007 | 
|Revenue days                       |  |                          | 9,700  |   |      |   | 17,538 |      |  |   | 17,421 |  
|Average number of marketed rigs    |  |                          | 71.0   |   |      |   | 71.0   |      |  |   | 70.5   |  
|Marketed rig utilization rates     |  |                          | 37.4   | % |      |   | 67.5   | %    |  |   | 68.0   | %
|Revenue per revenue day            |  | $                        | 17,415 |   |      | $ | 17,264 |      |  | $ | 16,591 |  
|Operating expenses per revenue day |  | $                        | 11,129 |   |      | $ | 11,181 |      |  | $ | 9,867  |  

As a result of the decline in natural
gas prices commencing in the second half of 2008, overall demand for drilling services correspondingly decreased. Consequently, we experienced a drop in our marketed rig utilization during 2009 compared to 2008 which primarily affected certain of
our smaller rigs and caused our revenue days to decrease. Revenue per revenue day for 2009 was favorably impacted by tolling agreements that we entered into in late March 2009 related to two rigs for which the operator elected to pay a stand-by or
tolling rate rather than to operate them. Tolling rigs provide revenue without contributing any revenue days, and therefore, increase the calculated revenue per revenue day amount. For 2009, these tolling rigs increased revenue per revenue day by
$262 and operating expense per revenue day by $31. In addition, the increase in revenue per revenue day in 2009 was partially attributable to three of the four rigs that we deployed in the first half of 2009 under term contracts (the fourth rig is
on tolling) and decreased utilization of our smaller rigs which earn a lower dayrate than our larger rigs. Offsetting these increases was the unfavorable impact of term contracts with higher dayrates that expired during 2009 and were reset at lower
dayrates from a depressed market.

Revenue days increased slightly in 2008 compared to 2007 primarily due to four new large rigs deployed in
the latter part of the third quarter of 2008. This increase in revenue days was partially offset by the continued decline in demand for smaller rigs in our fleet, resulting in the slight decrease in the marketed rig utilization rates. The increase
in revenue per revenue day and operating expenses per revenue day in 2008 compared to 2007 was primarily related to the new rigs placed into service during the latter part of the third quarter of 2008. In addition, operating expenses per revenue day
in 2008 grew more rapidly than revenue per revenue day due to higher employment costs, repairs and maintenance, fuel and supplies which we were not able to fully pass through to our customers.

We devote substantial resources to maintaining and upgrading our rig fleet. On a regular basis, we remove certain rigs from service to perform
upgrades. In the short term, these actions result in fewer revenue days and slightly lower utilization; however, in the long term, we believe the upgrades will help the marketability of the rigs and improve their operating
performance.

Critical Accounting Policies and Estimates

Revenue and cost recognition.We generate revenue principally by drilling wells for natural gas producers under daywork or footage contracts, which provide for the drilling of single or
multiple well projects. Revenues on daywork contracts are recognized based on the days worked at the dayrate each contract specifies. Mobilization fees are recognized as the related drilling services are provided. We recognize revenues on footage
contracts based on the footage drilled for the applicable accounting period. Expenses are recognized based on the costs incurred during that same accounting period. Reimbursements received for out-of-pocket expenses are recorded as revenues and
direct expenses.

Accounts receivable.We evaluate the creditworthiness of our customers based on their financial information,
if available, information obtained from major industry suppliers, and our past experiences, if any, with the customer. In some instances, we require new customers to make prepayments. We typically invoice our customers semi-monthly during the
performance of the contracts and upon completion of the contract, with payment due within 30 days. We established an allowance for doubtful accounts of $1.4 million and $1.5 million at December 31, 2009 and 2008, respectively. Any allowance
established is subject to judgment and estimates made by management. We determine our allowance by considering a number of factors, including the length of time trade accounts receivable are past due, our previous loss history, our assessment of our
customers current abilities to pay obligations to us and the condition of the general economy and the oil and gas industry as a whole. Our bad debt expense was $1.1 million, $6.3 million and $837,000 for 2009, 2008 and 2007, respectively. We
write off specific accounts receivable

when we determine they are uncollectible. During 2009, we wrote off $1.2 million of accounts receivable for two customers. During 2008, we wrote off $5.1 million of accounts receivable, primarily
for four customers, three of which subsequently declared bankruptcy. We are pursuing our claims in the bankruptcy proceedings.

At
December 31, 2009 and 2008, our unbilled receivables totaled $1.6 million and $4.4 million, respectively, all of which relates to the revenue recognized, but not yet billed, on contracts in progress at December 31, 2009 and 2008,
respectively. The $2.8 million decrease at December 31, 2009 compared to December 31, 2008 is due to lower utilization and increased progress billings during 2009, and the absence of a $1 million contract settlement payment we received in
January 2009.

Asset impairments.We assess the impairment of long-lived assets whenever events or circumstances indicate that
the assets carrying value may not be recoverable. Factors that could trigger an impairment review would be any significant negative trends in the industry or the general economy, our contract revenue rates, our rig utilization rates, cash
flows generated from operating our drilling rigs, existence of term drilling contracts, current and future oil and natural gas prices, industry analysts outlook for the oil and gas industry and their view of our customers access to
capital and the trends in the price of used drilling equipment observed by our management. If a review of our long-lived assets indicates that our carrying value exceeds the estimated undiscounted future cash flows, an impairment charge is made to
adjust the carrying value to the estimated fair value. Cash flows are estimated by management considering factors such as expectations of future industry trends and the impact on dayrates, utilization and operating expenses; historical performance
of the asset; the remaining expected life of the asset; any cash investment required to make the asset more marketable; suitability, specification and size of the rig; terminal value, as well as overall competitive dynamics. Use of different
assumptions could result in an impairment charge different from that reported.

During 2009, business conditions were challenging for the
drilling industry, rivaling one of the worst contractions the industry has seen since the 1980s, requiring us to evaluate our long-lived assets for impairment. Based on our assessment, $4.1 million of impairment was recognized for the year
ended December 31, 2009. Estimated fair value was determined using significant unobservable inputs (Level 3) based on both an income approach and a market approach. The income approach was calculated as the estimated discounted future net cash
flows assumed to be received from the operation of the asset over its useful life and a terminal value, while market was based on external industry data for similar equipment. The Companys assessment of the significance of a particular input
to the fair value measurement requires judgment and may affect the valuation of nonfinancial assets and liabilities and their placement within the fair value hierarchy levels. In the event that current market conditions do not improve, the Company
may be required to record additional impairment of its long-lived assets in the future, and such an impairment expense, even though non-cash, could be material and negatively impact our earnings.

Depreciation. We provide for depreciation of our drilling rigs, transportation and other equipment on a straight line method over
useful lives that we have estimated and that range from two to 12 years. Unlike depreciation based on units-of-production, our approach to depreciation does not change when equipment becomes idle or when utilization changes. We continue to
depreciate idled equipment on a straight-line basis despite the fact that our revenues and operating costs may vary with changes in utilization levels. Our estimates of the useful lives of our drilling, transportation and other equipment are based
on our experience in the drilling industry with similar equipment.

Intangible assets.Our customer list is amortized over the
estimated benefit period which was initially determined to be 20 years, but in 2009, was revised to 10 years based on actual historical customer turnover. This change in estimate, from 16.3 years remaining at December 31, 2008 to 5.3 years
remaining at December 31, 2009, increased the annual amortization from $110,000 to $300,000.

Deferred taxes.We record
deferred taxes for the basis difference in our property and equipment between financial reporting and tax reporting purposes and other costs such as compensation, employee benefits and other accrued liabilities which are deductible in different
periods for financial reporting and tax reporting purposes. For property and equipment, basis differences arise from differences in depreciation periods and methods and the value of assets acquired in a business acquisition where we acquire the
stock of an entity rather than its assets. For financial reporting purposes, we depreciate the various components of our drilling rigs and refurbishments over two to 12 years, while federal income tax rules require that we depreciate drilling rigs
and refurbishments over five years. In 2009 and 2008, tax depreciation also included bonus depreciation allowed as a result of the American Recovery and Reinvestment Act of 2009 and the Economic Stimulus Act of 2008, respectively. Therefore, in the
earlier years of our ownership of a drilling rig, our tax depreciation exceeds our financial reporting depreciation, resulting in our recording deferred tax liabilities on this depreciation difference. In later years, financial reporting
depreciation exceeds tax depreciation, and the deferred tax liability begins to reverse.

Accrued workers compensation.The Company accrues for costs under our workers
compensation insurance program in accrued expenses and other liabilities. We have a deductible of $100,000 per covered accident under our workers compensation insurance. Our insurance policies require us to maintain letters of credit to cover
our deductible payments. As of December 31, 2009 and 2008, we satisfied this requirement with letters of credit totaling $4.8 million and $3.5 million, respectively. We accrue for these costs as claims are incurred based on cost estimates
established for each claim by the insurance companies providing the administrative services for processing the claims, including estimates for incurred but not reported claims, claims paid directly by us, administrative costs associated with these
claims and our historical experience with these types of claims. In addition, as needed, we accrue the estimated workers compensation premium payable to Ohio, a monopolistic state, when our rigs work in that state.

Some of our employees engaged in our Texas field operations were previously considered to be shared employees. Under this arrangement, we
paid a fee for certain human resource functions, including the workers compensation and payroll liabilities, to be assumed by the third-party professional employer organization (PEO). This PEO arrangement in Texas was terminated
effective August 2, 2009, and such employees are now covered under our workers compensation insurance program.

Stock-based
compensation.Compensation cost resulting from share-based payment awards are measured at fair value and recognized in general and administrative expense on a straight line basis over the requisite service period. The amount of compensation
cost recognized at any date is at least equal to the portion of the grant-date fair value of the award that is vested at that date. For the years ended December 31, 2009, 2008 and 2007, the Company recorded stock-based compensation expense of
$1.8 million ($1.1 million net of tax), $2.1 million ($1.5 million net of tax), and $968,000 ($741,000 net of tax), respectively. Total unamortized stock-based compensation was approximately $3.3 million at December 31, 2009, and will be
recognized over a weighted average service period of 3.7 years.

Any tax benefit realized from stock options exercised is included as a cash
inflow from financing activities on the statement of cash flows.

Estimating the fair value of options granted requires us to utilize
valuation models and to establish several underlying assumptions. The fair value of option grants was estimated using the Black-Scholes option valuation model based on the following weighted average assumptions:



|                        |  |             |  |             |  |            
|----------------------- |  | ----------- |  | ----------- |  | -----------
|                        |  | 2009        |  | 2008        |  | 2007       
|Risk-free interest rate |  | 2.1% - 2.6% |  | 1.6% - 2.5% |  | 3.1% - 4.6%
|Expected life           |  | 5 years     |  | 5 years     |  | 2 - 5 years
|Dividend yield          |  | 0%          |  | 0%          |  | 0%         
|Expected volatility     |  | 74% - 75%   |  | 52% - 61%   |  | 44% - 47%  

The risk-free interest
rate is the implied yield available for zero-coupon U.S. government issues with a remaining term equal to the expected life of the options.

The expected lives of the options are determined based on the Companys expectations of individual option holders anticipated behavior and the term of the option.

The Company has not paid out dividends historically; thus, the dividend yield is estimated at zero percent.

Volatility is based upon price performance of the Company and a peer company, as the Company does not have a sufficient historical price base to determine potential volatility over the term of the issued
options.

Results of Operations

Our operations primarily consist of drilling natural gas wells for our customers under either daywork contracts and, to a lesser extent, footage contracts. Contract terms we offer generally depend on the complexity and risk of operations,
the on-site drilling conditions, the type of equipment used, the anticipated duration of the work to be performed and the overall demand for rigs in our markets. Our contracts generally provide for the drilling of a specified number of wells or
a specific period of time for which the rig will be under contract.

Revenues.The $133.9 million, or 44% decrease in revenues in 2009 compared to 2008 was primarily due to the decrease in our marketed rig utilization, from 67.5% in 2008 to 37.4% in 2009, as a result of the decline in the level of U.S. land-based natural
gas exploration and development activity.

Our revenues grew by $13.7 million, or 5%, in 2008 compared to 2007, primarily due to $12.1 million
of revenue related to four new large rigs being deployed in the latter part of the third quarter of 2008. Due to their greater capacity, these new rigs earned a higher day rate than our smaller rigs.

Operating expenses. The $88.1 million, or 45% decrease in operating expenses in 2009 compared to 2008 was also due to the decrease in our
marketed rig utilization. Employment costs, fuel, supplies and repairs and maintenance costs decreased as a result of having a greater number of idled rigs compared to the prior year.

Operating expenses increased $24.2 million, or 14%, in 2008 compared to 2007. The operating costs related to the four new rigs deployed in the latter part of the third quarter of 2008 were $6.7 million.
The remaining increase was due to increases in wages, vehicle and fuel expense, supplies and repairs and maintenance costs.

Depreciation and amortization.The $3.4 million, or 8% increase in depreciation and amortization expense in 2009 compared to 2008 was primarily due to the increase in depreciable assets. During the first half of 2009, rig
purchases and capital equipment upgrades were added to our fleet as part of our 2008 capital spending program which enhanced our fleet capabilities. Capital expenditures were $31.5 million in 2009.

Depreciation and amortization expense increased $5.2 million, or 13%, in 2008 compared to 2007 due to the increase in depreciable assets. Capital
expenditures for rig purchases and capital equipment upgrades were $104.8 million in 2008, of which $37.5 million represented construction in progress at December 31, 2008.

Impairment charge.During 2009, $4.1 million of impairment charges were recognized related to certain of our long-lived assets to write down the carrying value of these assets to fair value.

The $7.9 million impairment charge in 2008 is related to goodwill impairment recognized in the fourth quarter of 2008.

General and administrative expenses.The $9.3 million, or 27% decrease in 2009 compared to 2008 was primarily due to a $5.2 million decrease
in the provision for doubtful accounts, as well as decreased employment costs and other cost reductions in response to the decrease in operations.

Our general and administrative expenses increased by $9.3 million, or 38%, in 2008 compared to 2007. As a result of the deteriorating economy in late 2008 and its impact on specific customers, our provision for doubtful accounts increased
$5.5 million in 2008. Payroll expense increased $2.1 million primarily due to additional wages to professional and administrative employees and other stock-based compensation expense increased approximately $900,000. An additional $900,000 increase
related to safety expenses, other consulting fees and property taxes.

##### Table of Contents

Interest expense.There was no significant change in interest expense in 2009 compared to
2008. Interest expense decreased approximately $979,000 in 2008 compared to 2007, primarily due to the decrease in interest rates and higher capitalization of interest related to construction in progress during 2008.

Other income and gain on disposal of assets.The $808,000 decrease in other income and gain on disposal of assets is primarily due to fewer
gains on disposal of drillpipe as a result of lower utilization in 2009. In addition, 2008 includes a $400,000 gain on involuntary conversions related to rig damages.

Other income and gain on disposal of assets decreased $568,000 in 2008 compared to 2007 primarily due to the gains on sale of various utility vehicles at auction during the second quarter of 2007, and
partially offset by a $400,000 gain on involuntary conversions related to rig damages in 2008.

Taxes.Our
effective income tax rates of 26.7%, 61.9% and 41.7% for 2009, 2008 and 2007, respectively, differ from the federal statutory rate of 35%, primarily due to the non-deductible goodwill impairment charge in 2008, state income taxes and permanent
book/tax differences such as those associated with 50% deduction limitation on per diem meals expense, the domestic manufacturing deduction and stock-based compensation. See Note 6 to our Financial Statements for further information on our income
taxes.

At both December 31, 2009 and 2008, we had federal net operating loss carryforwards for income tax purposes of approximately
$98,000. These losses may be carried forward for 20 years and will begin to expire in 2023. State net operating loss carryforwards at December 31, 2009 and 2008 were $22.3 million and $1.3 million, respectively. State net operating loss
carryforwards vary as to carryforward period and will begin to expire in 2014, depending upon the jurisdiction where applied. In 2009, a valuation allowance of $61,000 was established for state net operating loss carryforwards in states where
utilization is uncertain due to lack of forecasted future operations. Based upon 2009 results and forecasted future operations, we believe it is more likely than not that the remaining amounts will be realized.

The Companys 2006, 2007 and 2008 U.S. federal income and employment tax returns are currently under examination by the I.R.S. Although we believe our
tax estimates are reasonable, the final determination of tax audits could be materially different than that which is reflected in our tax provisions and accruals.

Liquidity and Capital Resources

Our operations have historically generated sufficient cash
flow to meet our requirements for debt service and equipment expenditures (excluding major business and asset acquisitions). Cash flow provided by operating activities was $58.5 million, $73.0 million and $82.6 million during 2009, 2008 and
2007, respectively. The decrease in 2009 compared to 2008 was primarily due to the decrease in rig utilization in 2009. The decrease in cash flows provided by operating activities in 2008 compared to 2007 was primarily due to the higher operating
costs in 2008.

Our cash flow from operations primarily was used to invest in new machinery and equipment as well as for capitalized upgrades
to our fleet. During 2009, 2008 and 2007, cash used in investing activities totaled $43.9 million, $91.1 million and $65.8 million, respectively. The decrease in 2009 reflects the completion of our 2008 capital spending program.

Cash flow used in financing activities was $15.0 million for 2009. In June 2009, the Company completed a public offering consisting of 3.0 million
shares of newly issued common stock at a price of $8.25 per share. Proceeds to the Company, net of underwriting discounts and other fees and expenses, were $23.2 million and were used to repay indebtedness outstanding under the Companys
revolving credit facility. In the third quarter of 2009, we received refunds from the IRS of $6.4 million for 2006 taxes paid related to bonus depreciation claimed on our 2008 return. These refunds were also used to pay down indebtedness on our
revolving credit facility. In June 2009, we used $2.5 million in borrowings on our credit facility to pay off certain notes payable for equipment with interest rates higher than the revolving credit facility. In addition, in January 2009, we
purchased 285,182 shares of common stock for $1.6 million under a repurchase program. For the year ended December 31, 2008, our cash flow from financing activities was $18.4 million, consisting primarily of the $26.8 million increase in our net
borrowings on our Revolving Credit and Security Agreement and other debt, and partially offset by $8.9 million used for treasury stock purchases during the fourth quarter of 2008. The increase in our loan balance on our credit facility from $9.6

##### Table of Contents

million at December 31, 2007 to $42.6 million at December 31, 2008 was primarily the result of the excess of our cash paid for 2008 capital expenditures of $94.1 million over our $73.0
million cash flow from operations. During 2007, our cash flow used in financing activities was $16.8 million, primarily due to the $20.8 million net debt repayments and partially offset by $4.0 million in stock option exercise proceeds and related
tax benefit.

We believe cash generated by our operations and our ability to borrow the currently unused portion of our revolving credit
facility of approximately $83.7 million, after reductions for approximately $4.8 million outstanding letters of credit as of December 31, 2009, should allow us to meet our routine financial obligations for the foreseeable future.

Sources of Capital Resources

Our
rig fleet has grown from 12 rigs in 1997 to 71 marketed rigs at December 31, 2009. We have financed this growth with a combination of debt and equity financing, as well as operating cash flows. At December 31, 2009, our total
debt to total capital was approximately 4.3%.

See Note 8 of the financial statements, included in Item 8. Financial Statements and
Supplementary Data for a summary of our capital resources, such information being incorporated herein by reference.

Additions to drilling equipment during 2009 includes $18.3 million for progress payments related to four rigs that became
available for service during the second quarter of 2009, which were included in our 2008 capital spending program.

Our capital expenditures
program in 2008 included the purchase or partial payments associated with eight new rigs for which we had agreements with customers to deploy the rigs under term contracts. In addition, we upgraded and enhanced several of the existing rigs and
related equipment in our fleet. In particular, four rigs were upgraded with new 1,000 horsepower drawworks, and two new 550,000 pound derricks were installed and numerous rigs received higher horsepower mud pumps to facilitate longer reach
horizontal drilling. Most of this capital spending was tied to improved dayrates and extension of term contracts to provide a return on the incremental capital.

The $22.0 million decrease in our receivables at December 31, 2009 from December 31, 2008 was due primarily to the
significant decrease in revenues in 2009 compared to 2008. In addition, the December 31, 2008 balance includes $1 million of revenue we recognized as a result of our settlement with a customer under a drilling contract.

The $17.2 million decrease in accounts payable at December 31, 2009 is primarily the result of decreased capital spending and other operating expenses
in 2009 compared to 2008.

The $2.5 million decrease in current debt is primarily due to the $2.5 million early payoff of notes payable for
equipment with interest rates higher than our revolver.

Accrued expenses and other liabilities at December 31, 2009 decreased $4.6
million from December 31, 2008 primarily due to the $3.3 million decrease in accrued sales, franchise and property taxes due to payments in 2009 and $1.3 million decrease in accrued payroll expenses due to the decrease in headcount as a result
of the decrease in rig utilization.

Inflation

Inflation did not have a
significant effect on our results of operations in any of the periods reported. While we experienced some mild inflationary pressure in the second half of 2008 relating to labor, certain materials and equipment costs and fuel expense,
throughout 2009 we experienced no meaningful impacts to our business from any inflationary pressure. Management believes it is possible for some inflationary pressure to arise if the U.S. economic recovery becomes more certain; however, there
is no current belief that inflation will have a significant effect on our operations in the first half of 2010.

Off Balance Sheet
Arrangements

We do not currently have any off balance sheet arrangements.

Recently Issued Accounting Standards

See Note 2 of the financial statements, included in
Item 8. Financial Statements and Supplementary Data., for recently issued accounting standards, such information being incorporated herein by reference.



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

We are subject to market risk exposure related to changes in interest rates on our revolving credit facility, which provides for interest on borrowings under the facility at a floating rate. At
December 31, 2009, we had $9.0 million outstanding debt on our revolving credit facility. An increase or decrease of 1% in the interest rate would have a corresponding decrease or increase in our earnings of approximately $90,000 annually.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of

Union Drilling, Inc.

We have audited Union Drilling, Inc.s (the
Company) 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
(the COSO criteria). Union Drilling, Inc.s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the
accompanying Managements Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Companys internal control over financial reporting based on our audit.

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

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

Because of 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.

In our opinion, Union Drilling, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2009, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the balance sheets
of Union Drilling, Inc. as of December 31, 2009 and 2008 and the related statements of operations, stockholders equity and cash flows for each of the three years in the period ended December 31, 2009 and our report dated
March 5, 2010 expressed an unqualified opinion thereon.

UNION DRILLING, INC.

NOTES TO FINANCIAL STATEMENTS

1. Organization and Description of Business

Union Drilling, Inc. (Union Drilling, Company or
we), incorporated in Delaware in 1997, provides contract land drilling services and equipment, primarily to natural gas producers. In addition to our drilling rigs, we provide the drilling crews and most of the ancillary equipment needed
to operate our drilling rigs. We commenced operations with 12 drilling rigs and related equipment acquired from an entity providing contract drilling services under the name Union Drilling. Through a combination of acquisitions and new
rig construction, we have increased the size of our fleet to 71 marketed land drilling rigs. We presently focus our operations in selected natural gas production regions in the United States, primarily the Fort Worth Basin in North Texas, the
Arkoma Basin in Oklahoma and Arkansas and throughout the Appalachian Basin. We do not invest in oil and natural gas properties.

We market
our rigs to a number of customers, who are principally independent natural gas producers. Revenues from the top ten customers for the year ended December 31, 2009 represented 76% of total revenues with three customers revenue totaling
28%, 16% and 11%, respectively. Revenues from the top ten customers for the year ended December 31, 2008 represented approximately 56% of total revenues with two customers revenue totaling 18% and 12%, respectively. Revenues from the top
ten customers for the year ended December 31, 2007 represented approximately 60% of total revenues with two customers revenue totaling 14% and 13%, respectively.

2. Summary of Significant Accounting Policies

Basis of Presentation

The financial statements relate solely to the accounts of Union Drilling, Inc. The Company has no controlling financial interests in any entity which would
require consolidation. To conform with the December 31, 2009 presentation, the December 31, 2008 balance sheet includes a reclassification of income tax recoverable from prepaid expenses, deposits and other receivables.

Use of Estimates

The preparation of
financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual
results may differ from those estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity date of three months or less when purchased to be cash equivalents.

Accounts Receivable

We evaluate the
creditworthiness of our customers based on their financial information, if available, information obtained from major industry suppliers, and our past experiences, if any, with the customer. In some instances, we require new customers to make
prepayments. We typically invoice our customers semi-monthly during the performance of the contracts and upon completion of the contract, with payment due within 30 days. We established an allowance for doubtful accounts of $1.4 million and $1.5
million at December 31, 2009 and 2008, respectively. Any allowance established is subject to judgment and estimates made by management. We determine our allowance by considering a number of factors, including the length of time trade accounts
receivable are past due, our previous loss history, our assessment of our customers current abilities to pay obligations to us and the condition of the general economy and the oil and gas industry as a whole. We write off specific accounts
receivable when we determine they are uncollectible. See Note 4 for additional information on the allowance for doubtful accounts.

Our
contract drilling work in progress relates to the revenue recognized, but not yet billed, on contracts in progress at the balance sheet date.

Inventories

Inventories maintained by the Company are primarily engines, consumable replacement parts and drill bits. Inventories are maintained on a first-in, first-out basis, and recorded at the lower of cost or
net realizable value.

Prepaid Expenses, Deposits and Other Receivables

Prepaid expenses, deposits and other receivables include items such as insurance, taxes, utility deposits, fees and insurance claim receivables. We routinely expense our prepaid expenses in the normal
course of business over the periods these expenses benefit. A detail of prepaid expenses, deposits and other receivables is as follows:



|                               |  |              |       |      |   |

Goodwill and Intangible Assets

In light of the adverse market conditions affecting our common stock price beginning in the fourth quarter of 2008, we recorded an impairment charge of $7.9
million for goodwill associated with the 2005 purchase of Thornton Drilling Company. We utilized multiple market approaches to estimate the fair value of goodwill. In developing these fair value estimates, there was considerable judgment involved,
particularly in determining the valuation methodologies to utilize and the weighting of different valuation methodologies applied. Certain key assumptions included the trading day period over which to assess market capitalization, implied control
premium, multiple of earnings before interest, income taxes, depreciation and amortization and forecasted operating results. Our first step of the impairment test, which required us to compare the estimated fair value of the reporting unit to the
carrying value, indicated that our goodwill was impaired. We then measured the impairment by allocating the fair value to the identifiable assets and liabilities of the reporting unit based on respective fair values and there was no residual value
for goodwill; accordingly, we wrote off the entire carrying amount of goodwill.

Our customer list is amortized over the estimated benefit
period which was initially determined to be 20 years, but in 2009, was revised to 10 years based on actual historical customer turnover. This change in estimate, from 16.3 years remaining at December 31, 2008 to 5.3 years remaining at
December 31, 2009, increased the annual amortization from $110,000 to $300,000. Depreciation and amortization includes amortization of intangibles of $206,000, $281,000 and $403,000 for the years ended December 31, 2009, 2008 and 2007,
respectively.

The total cost and accumulated amortization of intangible assets are as follows (in thousands):



|                         |  |              |       |   |      |   |       |

Property, Buildings and Equipment

Property, buildings and equipment is stated at cost, net of accumulated depreciation. The Company capitalizes costs of replacements or renewals that improve or extend the lives of existing property,
buildings and equipment.

##### Table of Contents

Maintenance and repairs are expensed as incurred. Depreciation is calculated on the straight-line method over the estimated remaining useful lives of the assets. Depreciation on acquired or
constructed rigs and other components does not commence until the assets are placed in service. Once placed in service, depreciation continues when assets are being repaired, refurbished or between periods of deployment. As a result, our
depreciation charges will not vary with changes in utilization levels, unlike our revenue. Our estimates of the useful lives of our drilling, transportation and other equipment are based on our experience in the drilling industry with similar
equipment. For the years ended December 31, 2009, 2008 and 2007, depreciation expense was $47.5 million, $44.0 million and $38.7 million, respectively.

The estimated lives of the assets are as follows:



|                                    |  |              
|----------------------------------- |  | -------------
|Buildings                           |  | 30 - 40 years
|Drilling rigs and related equipment |  | 2 - 12 years 
|Vehicles                            |  | 5 - 7 years  

Impairment of
Long-Lived Assets

We assess the impairment of long-lived assets whenever events or circumstances indicate that the assets carrying
value may not be recoverable. Factors that could trigger an impairment review would be any significant negative trends in the industry or the general economy, our contract revenue rates, our rig utilization rates, cash flows generated from operating
our drilling rigs, existence of term drilling contracts, current and future oil and natural gas prices, industry analysts outlook for the oil and gas industry and their view of our customers access to capital and the trends in the price
of used drilling equipment observed by our management. If a review of our long-lived assets indicates that our carrying value exceeds the estimated undiscounted future cash flows, an impairment charge is made to adjust the carrying value to the
estimated fair value. Cash flows are estimated by management considering factors such as expectations of future industry trends and the impact on dayrates, utilization and operating expenses; historical performance of the asset; the remaining
expected life of the asset; any cash investment required to make the asset more marketable; suitability, specification and size of the rig; terminal value; as well as overall competitive dynamics. Use of different assumptions could result in an
impairment charge different from that reported.

Accrued Workers Compensation

The Company accrues for costs under our workers compensation insurance program in accrued expenses and other liabilities. We have a deductible of
$100,000 per covered accident under our workers compensation insurance. Our insurance policies require us to maintain letters of credit to cover our deductible payments. As of December 31, 2009 and 2008, we satisfied this requirement with
letters of credit totaling $4.8 million and $3.5 million, respectively. We accrue for these costs as claims are incurred based on cost estimates established for each claim by the insurance companies providing the administrative services for
processing the claims, including an estimate for incurred but not reported claims, claims paid directly by us, administrative costs associated with these claims and our historical experience with these types of claims. In addition, as needed, we
accrue the estimated workers compensation premium payable to Ohio, a monopolistic state, when our rigs work in that state.

Some of our
employees engaged in our Texas field operations were previously considered to be shared employees. Under this arrangement, we paid a fee for certain human resource functions, including the workers compensation and payroll
liabilities, to be assumed by the third-party professional employer organization (PEO). This PEO arrangement in Texas was terminated effective August 2, 2009, and such employees are now covered under our workers compensation
insurance program.

Stock-Based Compensation

Compensation cost resulting from share-based payment awards are measured at fair value and recognized in general and administrative expense on a straight line basis over the requisite service period. The
amount of compensation cost recognized at any date is at least equal to the portion of the grant-date fair value of the award that is vested at that date. For the years ended December 31, 2009, 2008 and 2007, the Company recorded stock-based
compensation expense of $1.8 million ($1.1 million net of tax), $2.1 million ($1.5 million net of tax), and $968,000 ($741,000 net of tax), respectively. Total unamortized stock-based compensation was approximately $3.3 million at December 31,
2009, and will be recognized over a weighted average service period of 3.7 years.

##### Table of Contents

Any tax benefit realized from stock options exercised is included as a cash inflow from financing activities
on the statement of cash flows.

Estimating the fair value of options granted requires us to utilize valuation models and to establish several
underlying assumptions. The fair value of option grants was estimated using the Black-Scholes option valuation model based on the following weighted average assumptions:



|                        |  |             |  |             |  |            
|----------------------- |  | ----------- |  | ----------- |  | -----------
|                        |  | 2009        |  | 2008        |  | 2007       
|                        |  |             | 
|Risk-free interest rate |  | 2.1% - 2.6% |  | 1.6% - 2.5% |  | 3.1% - 4.6%
|Expected life           |  | 5 years     |  | 5 years     |  | 2 - 5 years
|Dividend yield          |  | 0%          |  | 0%          |  | 0%         
|Expected volatility     |  | 74% - 75%   |  | 52% - 61%   |  | 44% - 47%  

The risk-free interest rate is
the implied yield available for zero-coupon U.S. government issues with a remaining term equal to the expected life of the options.

The
expected lives of the options are determined based on the Companys expectations of individual option holders anticipated behavior and the term of the option.

The Company has not paid out dividends historically; thus, the dividend yield is estimated at zero percent.

Volatility is based upon price performance of the Company and a peer company, as the Company does not have a sufficient historical price base to determine potential volatility over the term of the issued
options.

Revenue Recognition

We generate revenue principally by drilling wells for natural gas producers under daywork or footage contracts, which provide for the drilling of single or multiple well projects. Revenues on daywork contracts are recognized based on the
days worked at the dayrate each contract specifies. Mobilization fees are recognized as the related drilling services are provided. We recognize revenues on footage contracts based on the footage drilled for the applicable accounting period.
Expenses are recognized based on the costs incurred during that same accounting period. Reimbursements received for out-of-pocket expenses are recorded as revenues and direct expenses.

Concentration of Credit Risk

Substantially all of the Companys operations relate to
drilling services performed for independent oil and natural gas producers in the United States. The Company utilizes a fleet of land drilling rigs to provide these contract drilling services. These operations are aggregated into one reportable
segment based on the similarity of economic characteristics among all markets and the similarity of the nature of the services provided and the type of customers served.

Income Taxes

We record deferred taxes for the basis difference in our property and
equipment between financial reporting and tax reporting purposes and other costs such as compensation, employee benefits and other accrued liabilities which are deductible in different periods for financial reporting and tax reporting purposes. For
property and equipment, basis differences arise from differences in depreciation periods and methods and the value of assets acquired in a business acquisition where we acquire the stock of an entity rather than its assets. For financial reporting
purposes, we depreciate the various components of our drilling rigs and refurbishments over two to 12 years, while federal income tax rules require that we depreciate drilling rigs and refurbishments over five years. In 2009 and 2008, tax
depreciation also included bonus depreciation allowed as a result of the American Recovery and Reinvestment Act of 2009 and the Economic Stimulus Act of 2008, respectively. Therefore, in the earlier years of our ownership of a drilling rig, our tax
depreciation exceeds our financial reporting depreciation, resulting in our recording deferred tax liabilities on this depreciation difference. In later years, financial reporting depreciation exceeds tax depreciation, and the deferred tax liability
begins to reverse.

Earnings Per Share

Basic earnings per common share is computed by dividing net (loss) income by the weighted average number of common shares outstanding during the period. Diluted earnings per common share is computed by
dividing net income by the weighted average number of common shares outstanding during the period and the effect of all dilutive common stock equivalents, such as stock options and restricted stock units. The treasury stock method is used to compute
the assumed incremental shares related to our outstanding stock options and restricted stock units. The average common stock market prices for the periods are used to determine the number of incremental shares.

In periods where there is a net loss, diluted earnings per common share is equal to basic earnings per common share since the effect of including any
dilutive common stock equivalents would be antidilutive.

Other Comprehensive Income

For fiscal years 2009, 2008 and 2007, other comprehensive income equals net income.

Recent Accounting Pronouncements

Effective July 1, 2009, the Financial Accounting
Standards Board (FASB) Accounting Standards Codification (Codification) became the source of authoritative U.S. generally accepted accounting principles (GAAP). Any change to the FASB Codification will be
communicated through an Accounting Standards Update (ASU). The adoption of the Codification had no material effect on the financial condition or results of operations of the Company.

On January 1, 2009, the Company adopted the principles and requirements of the Business Combinations Topic of the FASB Codification. This Topic
establishes how the acquirer in a business combination: a) recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree; b) recognizes and measures the
goodwill acquired in the business combination or a gain from a bargain purchase; and c) determines what information to disclose to enable users of the financial statements to evaluate the nature and financial effects of the business combination.
This Topic applies prospectively to the Company for any business combinations for which the acquisition date is on or after January 1, 2009. Since there have been no business combinations in 2009, the adoption of this Topic did not have a
material impact on our financial position or results of operations.

For interim or annual financial periods ending after June 15, 2009,
the Subsequent Events Topic of the FASB Codification requires the disclosure of the date through which an entity has evaluated subsequent events and the basis for that date, that is, whether that date represents the date the financial statements
were issued or were available to be issued. The adoption of this Topics disclosure requirements did not have any effect on the financial condition or results of operations of the Company.

On January 1, 2009, the Company implemented the requirements of the Fair Value Measurements and Disclosures Topic of the FASB Codification as it
relates to non-financial assets and non-financial liabilities that are recognized or disclosed at fair value in an entitys financial statements on a non-recurring basis. The implementation of the requirements of this Topic as it relates to the
Companys non-financial assets and non-financial liabilities that are recognized or disclosed at fair value on a non-recurring basis did not have a material impact on our financial position or results of operations.

In October 2009, the FASB issued ASU No. 2009-13, amending Subtopic 605-25 Revenue Recognition  Multiple-Element Arrangements, which establishes
the accounting and reporting guidance for arrangements under which a vendor will perform multiple revenue-generating activities. This ASU amends the criteria for separating consideration in multiple-deliverable arrangements and expands the related
disclosures. This ASU will be effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010, with early adoption permitted. We do not expect the adoption of ASU
No. 2009-13 to have a material effect on the financial condition or results of operations of the Company.

In January 2010, the FASB
issued ASU No. 2010-06, amending Topic 820 Fair Value Measurements and Disclosures. This ASU updates Subtopic 820-10 and requires the following new disclosures: 1) disclose separately the amounts of significant transfers in and out of Level 1
and Level 2 fair value measurements and describe the reasons for the transfers; and 2) present separately in the reconciliation for fair value measurements using significant

unobservable inputs (Level 3), information about purchases, sales, issuances and settlements (on a gross basis rather than one net number). In addition, this ASU clarifies existing disclosures as
follows: 1) provide fair value measurement disclosures for each class of assets and liabilities (often a subset within a line item in the statement of financial position); and 2) provide disclosures about the valuation techniques and inputs used to
measure both recurring and nonrecurring Level 2 or Level 3 fair value measurements. These new disclosures and clarifications of existing disclosures are effective for interim and annual reporting periods beginning after December 15, 2009,
except for the disclosures about purchases, sales, issuances and settlements in the roll forward activity in Level 3 fair value measurements, which are effective for fiscal years beginning after December 15, 2010, and for interim periods within
those fiscal years. We do not expect the adoption of ASU No. 2010-06 to have a material impact on our financial condition or results of operations.

3. Fair Value Measurement

The Fair Value Measurements and Disclosures Topic of the FASB
Codification utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:



|         |  |                                                                                                                                                                                        
|-------- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|Level 1: |  | Observable inputs such as quoted prices for identical assets or liabilities in active markets                                                                                          
|Level 2: |  | Other inputs that are observable directly or indirectly, such as quoted prices for similar assets or liabilities or market-corroborated inputs                                         
|Level 3: |  | Unobservable inputs for which there is little or no market data and which require us to develop our own assumptions about how market participants would price the assets or
liabilities

At December 31, 2009, our financial instruments utilizing Level 1 inputs include cash and cash equivalents for
which quoted current market prices are readily available.

At December 31, 2009, our financial instruments utilizing Level 2 inputs
include accounts receivable, accounts payable, accrued liabilities, debt and notes payable. For these Level 2 instrument, we believe that recorded amounts approximate fair value due to the relative short maturity period. Further, the pricing
mechanisms in the Companys debt agreements combined with the short-term nature of the equipment financing arrangements result in the carrying values of these obligations approximating their respective fair values.

We do not have any financial instruments utilizing Level 3 inputs

During 2009, we recorded $4.1 million of impairment charges related to certain long-lived assets with a carrying amount of $23.0 million and an estimated fair value of $18.9 million. Estimated fair value
was determined using significant unobservable inputs (Level 3) based on both an income approach and a market approach. The income approach was calculated as the estimated discounted future net cash flows assumed to be received from the operation of
the asset over its useful life and a terminal value, while market was based on external industry data for similar equipment. The Companys assessment of the significance of a particular input to the fair value measurement requires judgment and
may affect the valuation of nonfinancial assets and liabilities and their placement within the fair value hierarchy levels.

During 2009, 2008 and 2007, we capitalized $636,000, $1.2 million and $909,000, respectively, of interest costs incurred
during the construction periods of certain drilling equipment.

During 2009, business conditions were challenging for the drilling industry,
rivaling one of the worst contractions the industry has seen since the 1980s, requiring us to evaluate our long-lived assets for impairment. Based on our assessment, $4.1 million of impairment was recognized for the year ended
December 31, 2009. See Note 3. Fair

During 2009 and 2008, the Company received tax refunds, net of payments made, of approximately $6.4 million and $2.6
million, respectively. During 2007, the Company made tax payments of approximately $14.0 million.

Deferred tax assets and liabilities are presented net in the balance
sheet according to their current or long-term classification.

The Company had federal net operating loss carryforwards of approximately
$98,000 at both December 31, 2009 and 2008. These losses may be carried forward for 20 years and will begin to expire in 2023. State net operating losses at December 31, 2009 and 2008, were $22.3 million and $1.3 million, respectively.
State losses vary as to carryforward period and will begin to expire in 2014, depending upon the jurisdiction where applied. In 2009, a valuation allowance of $61,000 was established for state net operating loss carryforwards in states where
utilization is uncertain due to lack of forecasted future operations.

At December 31, 2009 and 2008, we had approximately $208,000 and
$438,000, respectively, of unrecognized tax benefits, of which approximately $135,000 and $285,000, respectively, would affect our effective tax rate if recognized. Such amounts are carried as other long-term liabilities.

Interest and penalties related to uncertain tax positions are classified as interest expense and general and administrative
costs, respectively. During 2009, the Company recognized cost reversals of $96,000 in interest and penalty expense related to unrecognized tax benefits. During 2008, the Company recognized $82,500 in interest and penalties related to unrecognized
tax benefits. As of December 31, 2009 and 2008, the Company had $8,000 and $104,000, respectively, of interest and penalties accrued in relation to uncertain tax positions. It is reasonably possible that within the next 12 months, we may
resolve some or all of the uncertain tax positions as a result of negotiations with taxing authorities which would result in a decrease in unrecognized tax.

The Company files income tax returns in the U.S. federal and in various state jurisdictions, and, prior to 2007, in Canada. The tax years 2006 to 2008 remain open to examination by the major taxing
jurisdictions to which we are subject. In addition, tax years 1999, 2000, 2002 and 2003 remain open due to utilized losses in some jurisdictions in subsequent years. The Companys 2006, 2007 and 2008 U.S. federal return is currently under
examination by the IRS. Although the Company believes it has adequately provided for all tax positions, amounts asserted by taxing authorities could be greater than the Companys accrued position.

8. Debt Obligations

In March 2005, we
entered into a Revolving Credit and Security Agreement with PNC Bank, for itself and as agent for a group of lenders. This credit facility has been amended numerous times, most recently in September 2008. In addition to PNC Bank, the current group
of lenders consists of Capital One Leverage Finance Corp., M&I Business Credit, LLC, M&T Bank and TD Bank, N.A.. This credit facility matures on March 30, 2012 and provides for a $97.5 million borrowing base. Amounts outstanding under
the credit facility bear interest, depending upon facility usage, at either (i) the higher of the Federal Funds Open Rate plus 75 to 125 basis points or PNC Banks base commercial lending rate (4.5% at December 31, 2009) or
(ii) LIBOR plus 250 to 300 basis points (3.2% at December 31, 2009). Interest on outstanding loans is due monthly for domestic rate loans and at the end of the relevant interest period for LIBOR loans. Depending upon our facility usage, we
are assessed an unused line fee of 37.5 to 62.5 basis points on the available borrowing capacity. The available borrowing capacity was $83.7 million as of December 31, 2009. There is a $7.5 million sublimit for letters of credit. If we repay
and terminate the obligations under this facility, we will incur a substantial prepayment penalty. As of December 31, 2009, we had a loan balance of $9.0 million under the credit facility, and an additional $4.8 million of the total capacity
had been utilized to support our letter of credit requirement. As of December 31, 2008, $42.6 million was outstanding under our credit facility and $3.5 million of the total capacity was utilized to support our letter of credit requirement.

In general, the credit facility is secured by substantially all of our assets The forced liquidation value
of our assets serving as collateral is determined annually by an independent appraisal, with adjustments for acquisitions and dispositions between appraisals. The credit facility contains affirmative and negative covenants and also provides for
events of default that are typical for such an agreement. Among the affirmative covenants are requirements to maintain a specified tangible net worth and a fixed charge coverage ratio. As of December 31, 2009, our actual tangible net worth was
$214.7 million compared to the required minimum tangible net worth of $74.9 million, while our actual fixed charge coverage ratio of 6.2 exceeded the required 1.1 fixed charge coverage ratio. Among the negative covenants are restrictions on major
corporate transactions, incurrence of indebtedness and amendments to our organizational documents. Events of default would include a change in control and any change in our operations or condition, which has a material adverse effect. As of
December 31, 2009, we were in compliance with all of our financial covenants.

To date, the credit facility primarily has been used to
pay for rig acquisitions and for our working capital requirements. The credit facility may also be used by the Company, subject to certain conditions, to repurchase its common stock and/or pay a cash dividend.

In addition, the Company has entered into various equipment-specific financing agreements with a third-party financing institution. The terms of these
agreements range from 24 to 48 months. In June 2009, we used $2.5 million in borrowings on our credit facility to pay off certain of these notes payable with interest rates higher than the revolving credit facility. As of December 31, 2009 and
2008, the total outstanding balance under these arrangements was approximately $771,000 and $5.1 million, respectively, and is classified, according to payment date, in current portion of notes payable for equipment and long-term notes payable for
equipment in the accompanying balance sheets. At December 31, 2009, the stated interest rate on these borrowings ranges from zero percent to 4.2%.

The following is a schedule, by year, of the future debt payments under these agreements, together with the present value of the net payments as of December 31, 2009 (in thousands):

Equity Based Plans

The Company has two equity based plans, the Amended and Restated 2005
Stock Incentive Plan and the Amended and Restated 2000 Stock Option Plan. Under each plan, 1,579,552 shares of the Companys common stock have been authorized for awards of stock options. Under both plans, incentive and non-qualified stock
options may be awarded to directors and employees. Restricted stock and restricted stock units may be granted under the Amended and Restated 2005 Stock Incentive Plan. As of December 31, 2009, 1,095,734 options and 303,319 restricted stock
units have been granted under the Amended 2005 Stock Option Plan and 1,548,124 options have been granted under the Amended and Restated 2000 Stock Option Plan. Stock options are granted with an exercise price equal to the fair market value on the
grant date, which is determined by the closing trading price of our common stock on the Nasdaq Global Select Market. Prior to the Companys initial public offering in November 2005, the exercise price of stock options were based on the Board of
Directors assessment of the fair market value of the stock at the time the options were granted.

Stock options. Options
typically vest in four equal annual installments from the grant date, depending on the terms of the grant, and, unless earlier exercised or forfeited, expire on the tenth anniversary of the grant date. A summary of stock option activity was as

Employee Benefit Plan

The Company has a defined contribution employee benefit plan covering substantially all of its employees. Company contributions to the plan are
discretionary. The Company made contributions of approximately $275,000, $585,000 and $479,000 during the years ended December 31, 2009, 2008 and 2007, respectively.

Contingent Management Compensation

The Companys Chief Executive Officer
(CEO) and certain other participants have been awarded rights to participate in the proceeds associated with the appreciation in value ultimately associated with dispositions of the Companys shares by Union Drilling Company LLC
(UDC), our principal stockholder. In order to receive benefits from this arrangement, the fair market value of the Companys shares held by UDC must exceed certain threshold amounts.

The CEO is to receive benefits as a result of UDCs sale, distribution or disposition of Company shares and the related recognition of a gain in excess
of the threshold amount. These rights may be repurchased from the CEO at fair market value, which includes consideration of the threshold amount in the determination of that value, upon his termination of employment by the Company. Further, the
rights may be repurchased from the CEO for no consideration upon voluntary termination or upon termination of employment by the Company for cause.

At December 31, 2009 and 2008 the threshold amounts were $38.7 million and $35.2 million, respectively. These amounts are determined based upon cash invested in UDC (and invested by UDC in the Companys stock) plus a compounded
annual return of 10% less cash returned to investors. In 2009 and 2007, $12,000 and $26,000, respectively, of compensation costs were recognized as a result of the fair value of the assets owned by UDC exceeding the threshold. In 2008, the Company
recognized $218,000 of compensation cost reversals as a result of the decrease in the market value of the Companys common stock price. All compensation costs related to these rights are classified as general and administrative expense. As
UDC is responsible for the cash settlement of these awards, the offsetting balance is recorded as additional paid in capital.

The defined
participants in this arrangement would be entitled to up to 22.5% of the value realized in excess of the threshold amount. The CEO is entitled to approximately 1% of the 22.5%.

11. (Loss) Earnings Per Common Share

Because we incurred a net loss for the year ended December 31, 2009, basic and diluted loss per share were calculated as our net loss divided by the weighted average shares outstanding. Excluded from
the computation of diluted loss per share for the year ended December 31, 2009 were 579,732 weighted average options and restricted stock units because the effect of including them would have been antidilutive.

For the years ended December 31, 2008 and 2007, the following table presents a reconciliation of the numerators and denominators of the basic earnings
per share and diluted earnings per share computations:

12. Commitments and Contingencies

Operating Leases

The Company leases
certain buildings, automobiles, office equipment and phone services under noncancelable operating agreements. Lease expense was approximately $2.2 million, $2.3 million and $2.1 million for the years ended December 31, 2009, 2008 and 2007,
respectively. As of December 31, 2009, future minimum lease payments under noncancelable operating leases consist of the following (in thousands):

|      |  |   |      

Litigation and Other Contingencies

From time to time, we are a party to claims, litigation or other legal or administrative proceedings that we consider to arise in the ordinary course of our
business. While no assurances can be given regarding the outcome of these or any other pending proceedings, or the ultimate effect such outcomes may have, we do not believe we are a party to any legal or administrative proceedings which, if
determined adversely to us, individually or in the aggregate, would have a material effect on our financial position, results of operations or cash flows. Management believes that the Company maintains adequate levels of insurance necessary to cover
its business risk.

On October 31, 2008, the Company was named in a lawsuit filed in the United States District Court for the Eastern
District of Arkansas (Western Division). The lawsuit was filed by Stephen Rose, individually, and Elizabeth Rose, both individually and on behalf of the deceased children of Stephen and Elizabeth Rose. The lawsuit alleges

negligence on behalf of the Company relating to a traffic accident involving a mobile drilling rig owned by the Company. The Roses children were fatally injured in this accident. The
lawsuit seeks unspecified compensatory and punitive damages. The Company is vigorously defending itself in this litigation.

The
Companys 2006, 2007 and 2008 U.S. federal income and employment tax returns are currently under examination by the I.R.S. Although we believe our tax estimates are reasonable, the final determination of tax audits and any related litigation
could be materially different than that which is currently reflected in our tax provisions and accruals. The final outcome of this examination is not determinable at this time.

Evaluation of
Disclosure Controls and Procedures.

As of the end of the period covered by this report, we carried out an evaluation, under the
supervision and with the participation of management, including our Chief Executive Officer and Interim Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in 13a-15(e) of the Securities Exchange Act
of 1934, or the Exchange Act). Based on that evaluation, our Chief Executive Officer and our Interim Chief Financial Officer concluded that our disclosure controls and procedures are effective.

Managements Report on Internal Control over Financial Reporting.

Management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934). Our internal
control over financial reporting is designed to provide reasonable assurance to management and the Board of Directors regarding the preparation and fair presentation of published financial statements. Because of its inherent limitations, internal
control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Management
assessed the effectiveness of our internal control over financial reporting as of December 31, 2009. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission
(COSO) in Internal Control  Integrated Framework.Based on our assessment, we believe that, as of December 31, 2009, our internal control over financial reporting is effective based on those criteria.

Attestation Report of Independent Registered Public Accounting Firm.

The attestation report of our independent registered public accounting firm regarding internal control over financial reporting is set forth in Item 8 of this Annual Report on Form 10-K under the
caption Report of Independent Registered Public Accounting Firm Report and is incorporated herein by reference.

Changes in
Internal Control over Financial Reporting.

No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and
15d-15(f) under the Exchange Act) occurred during the fiscal quarter ended December 31, 2009 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
