2012 as well as 2013 are transition years for Comstock as we are changing 
from a company with 98% of its reserves being natural gas to one with more 
balance between oil and natural gas.  We started 2012 with a promising Eagle 
Ford shale oil program and added a new core area in the Permian Basin.  In 
2012, we saw natural gas prices decrease 36% from 2011 and our natural 
gas production decline by 9%.  But we also saw our oil production grow by 
175% from 2011 with our Eagle Ford shale properties becoming our main 
growth engine.  Oil production made up 14% of our total production in 
2012 as compared to only 5% in 2011.  Given the weak natural gas prices, oil 
accounted for 53% of our total sales in 2012 as compared to only 18% in 2011.
Our Wolfbone field in West Texas has tremendous potential to be a second 

growth engine both from proven vertical well development and from the 
emerging Wolfcamp shale horizontal well development.  Our properties in the 
Haynesville and Bossier shales in East Texas and North Louisiana provide us 
with over 6 Tcfe of upside when natural gas prices support drilling again.  
In the face of deteriorating natural gas prices, we completed several 

transactions in 2012 to improve our financial profile. We were able to reduce 
the leverage we took on at the end of 2011 with the Permian Basin acquisition 
with several asset divestitures which generated $204 million in net proceeds.  
We also completed a bond offering which freed up over $200 million of our 
bank credit facility.  And lastly we entered into a joint venture on our Eagle 
Ford shale properties which allowed us to accelerate our drilling activity in 
South Texas starting in late 2012.

Our oil production increased 175% in 2012 driven by our oil focused drilling 

program while natural gas production declined by 9%.  Natural gas prices in 
2012 declined 36%.  The higher oil production was mostly offset by the weaker 
natural gas prices and lower natural gas production as our oil and gas sales, 
including realized gains from our oil hedging program, increased by 2% to $442 
million as compared to $434 million in 2011.

In 2012, oil made up 53% of our sales as compared to only 18% in 2011.  
We generated operating cash flow of $261 million in 2012 which was 12% 
less than 2011’s operating cash flow of $298 million.  Our operating costs 
increased 30% in 2012 to $102 million as compared to $79 million in 2011.  
The increase is attributable to the higher lifting costs associated with the 
increased oil production.  Depreciation, depletion and amortization in 2012 of 
$365 million increased 25% as compared to the $291 million we had in 2011.  
Our depreciation, depletion and amortization per Mcfe produced increased 
to $3.83 in 2012 from $3.00 in 2011 due to the higher finding costs of our oil 
projects combined with the downward revisions to our proved undeveloped 
natural gas reserves related to the low 2012 natural gas prices.  Our general 
and administrative expenses in 2012 decreased to $34 million as compared 
to $35 million in 2011.  Our exploration costs increased in 2012 to $61 
million as compared to $10 million in 2011.  The increase in 2012 was due to 
impairments of certain of our natural gas undrilled leases which we no longer 
expect to develop.  Our interest expense increased to $65 million in 2012 as 
compared to $43 million in 2011 due to the increase in the amount of debt 
we had outstanding.  With the low outlook for natural gas prices for 2013, we 
recorded an impairment of $25 million to write down the carrying value of 
certain of our natural gas fields.  We also had realized gains of $51 million on 
sales of our marketable securities and oil and gas properties.  For the year we 
reported a net loss of $100 million or $2.16 per share.

D r i l l i n g   P r o g r a m 

Our Eagle Ford shale horizontal well drilling program in South Texas and 
our Wolfbone vertical well drilling program in West Texas were the primary 
drivers of growth in our oil production and proved oil reserves in 2012.  Our 
successful drilling program in the Eagle Ford shale in South Texas added 11.9 
million barrels of oil and 7.5 Bcf of natural gas to our proved reserves in 2012.  
The West Texas drilling program contributed 5.4 million barrels of oil and 9.5 
Bcf to our proved reserves in 2012.  Our limited activity in the Haynesville 
shale and other regions added 14 Bcf of proved natural gas reserves in 2012.  
We spent $490 million for our drilling activities in 2012 (net of reimbursements 
from our Eagle Ford shale joint venture) and an additional $35 million to 
acquire leases for future exploration and development activities.  In 2013, we 
plan on focusing primarily on our oil projects in the Eagle Ford shale in South 
Texas and in the Wolfbone and Wolfcamp shale in West Texas.

Our costs to drill and 
complete these wells are 
down considerably which 
is allowing us to drill 33% 
more net wells in 2013 
with only an 8% higher

S o u t h   T e x a s   R e g i o n 

In our South Texas region we have 32.8 million barrels of oil equivalent in 
reserves which is 28% of our total reserves.  56% of our reserves in this region 
are oil. We have 35,000 acres (28,000 net) in South Texas that are in the oil 
window of the Eagle Ford shale play.   This region accounted for 73% of our oil 
production in 2012 at 4,600 barrels of oil per day and 11% of our natural gas 
production at 24 MMcf per day.  Natural gas production in this region fell by 
23% in 2012 but oil production increased 140% as a result of our Eagle Ford 
shale drilling program.  We spent $203 million in 2012 to drill 30 (20.5 net) 
horizontal Eagle Ford shale wells.  These wells had an average per well initial 
production rate of 675 barrels of oil equivalent per day.  We plan to spend $219 
million in 2013 to drill 42 (27.3 net) Eagle Ford shale horizontal wells.  Our 
costs to drill and complete these wells are down considerably which is allowing 
us to drill 33% more net wells in 2013 with only an 8% higher spending level.

W e s t   T e x a s   R e g i o n

In our West Texas region we have 26.8 million barrels of oil equivalent in 
reserves which is 23% of our total reserves.  76% of our reserves in this region 
are oil. We have 89,000 acres (54,000 net) in the Permian Basin in West Texas.  
We believe that these properties are prospective for oil development primarily 
in the Avalon, Bone Spring and Wolfcamp shales.  This region accounted for 
22% of our oil production at 1,400 barrels of oil per day and less than 1% of our 
natural gas production at 2 MMcf per day.  We spent $184 million in 2012 to 
drill 48 (30.5 net) wells.  These wells had an average per well initial production 
rate of 322 barrels of oil equivalent per day.  We plan to spend $169 million in 
2013 to drill 33 (27.2 net) wells including eight horizontal wells targeting the 
Wolfcamp shale.  

E a s t   T e x a s / N o r t h   L o u i s i a n a   R e g i o n 

At the end of 2012, we had 342 Bcfe of our proved reserves (48%) in our East 

Texas/North Louisiana region.  The properties in this region are essentially 
all natural gas.  In response to the very low natural gas prices we discontinued 
drilling in this region and moved all of our operating drilling rigs to our oil 
regions during the first quarter of 2012.  As a result our production from this 
region, which averaged 196 MMcfe per day in 2012, declined by 8% from 2011.  
Most of our proved undeveloped reserves in this region had to be written off by 
the end of 2012 due to the low average natural gas price in 2012.  In 2012, we 
spent $101 million in this region to drill seven wells (3.2 net) and to complete 
16 wells (10.4 net) that were drilled in 2011.  We currently have 94,000 gross 
acres and 80,000 net acres that we believe are prospective for Haynesville or 
Bossier shale development. We believe that our acreage has over 6 Tcfe of 
combined reserve potential for these two plays.  We expect to have minimal 
activity in this region in 2013 unless natural gas prices improve.

We anticipate the 
strong growth in our 
oil production to offset the 
low natural gas prices 
to allow us to have higher 
revenues and cash flow 
and to be a much more 
profitable company 
in 2013.

O t h e r   R e g i o n s 

We have 12 Bcfe in the San Juan basin, Mid-Continent and in other 

areas.  Our properties in the other regions accounted for 2% of our 2012 daily 
production at 6 MMcfe per day.  We plan to continue to divest of many of 
these assets on an opportunistic basis.

O u t l o o k   f o r   2 0 1 3

Despite the continued low natural gas prices we are experiencing, we are 
excited about the prospects for Comstock in 2013.  We anticipate the strong 
growth in our oil production to offset the low natural gas prices to allow us to 
have higher revenues and cash flow and to be a much more profitable company 
in 2013.  We expect oil to comprise more than 25% of our 2013 production as 
94% of the wells that we expect to drill will be oil wells and 92% of our budget 
is expected to be spent on oil projects.  Our Eagle Ford shale program will be 
our largest growth engine this year.  We also see tremendous upside in future 
horizontal development in the emerging Wolfcamp shale based on recent 
activity in Reeves County, Texas.

We will strive to continue to have one of the lowest overall cost structures 
in the industry even as we transition to oil.  We believe that we have adequate 
liquidity for our 2013 drilling plans.  We expect operating cash flow to fund 
most of our planned drilling program and that the availability under our bank 
credit facility will increase with our oil reserve growth.  We will continue 
utilizing an oil price hedging strategy to protect our oil focused drilling 
program.

A major goal for Comstock in 2013 is to improve our balance sheet.  We also 

want to bring in more capital for our oil focused drilling program.  We expect 
to accomplish this at the asset level by entering into a joint venture or selling a 
portion of our large acreage position in the Permian Basin.

The directors and management of Comstock want to thank the stockholders 

for their continued support.

DEFINITIONS

The following are abbreviations and definitions of terms commonly used in the oil and gas industry
and this report. Natural gas equivalents and crude oil equivalents are determined using the ratio of six
Mcf to one barrel. All references to “us,” “our,” “we” or “Comstock” mean the registrant, Comstock
Resources, Inc. and where applicable, its consolidated subsidiaries.

“Bbl” means a barrel of U.S. 42 gallons of oil.

“Bcf” means one billion cubic feet of natural gas.

“Bcfe” means one billion cubic feet of natural gas equivalent.

“BOE” means one barrel of oil equivalent.

“Btu” means British thermal unit, which is the quantity of heat required to raise the temperature of

one pound of water from 58.5 to 59.5 degrees Fahrenheit.

“Completion” means the installation of permanent equipment for the production of oil or gas.

“Condensate” means a hydrocarbon mixture that becomes liquid and separates from natural gas

when the gas is produced and is similar to crude oil.

“Development well” means a well drilled within the proved area of an oil or gas reservoir to the

depth of a stratigraphic horizon known to be productive.

“Dry hole” means a well found to be incapable of producing hydrocarbons in sufficient quantities

such that proceeds from the sale of such production exceed production expenses and taxes.

“Exploratory well” means a well drilled to find and produce oil or natural gas reserves not
classified as proved, to find a new productive reservoir in a field previously found to be productive of oil
or natural gas in another reservoir or to extend a known reservoir.

“GAAP” means generally accepted accounting principles in the United States of America.

“Gross” when used with respect to acres or wells, production or reserves refers to the total acres or

wells in which we or another specified person has a working interest.

“MBbls” means one thousand barrels of oil.

“MBbls/d” means one thousand barrels of oil per day.

“Mcf” means one thousand cubic feet of natural gas.

“Mcfe” means one thousand cubic feet of natural gas equivalent.

“MMBbls” means one million barrels of oil.

“MMBOE” means one million barrels of oil equivalent.

“MMBtu” means one million British thermal units.

3

“MMcf” means one million cubic feet of natural gas.

“MMcf/d” means one million cubic feet of natural gas per day.

“MMcfe/d” means one million cubic feet of natural gas equivalent per day.

“MMcfe” means one million cubic feet of natural gas equivalent.

“Net” when used with respect to acres or wells, refers to gross acres of wells multiplied, in each

case, by the percentage working interest owned by us.

“Net production” means production we own less royalties and production due others.

“Oil” means crude oil or condensate.

“Operator” means the individual or company responsible for the exploration, development, and

production of an oil or gas well or lease.

“PV 10 Value” means the present value of estimated future revenues to be generated from the
production of proved reserves calculated in accordance with the Securities and Exchange Commission
guidelines, net of estimated production and future development costs, using prices and costs as of the date
of estimation without future escalation, without giving effect to non-property related expenses such as
general and administrative expenses, debt service, future income tax expense and depreciation, depletion
and amortization, and discounted using an annual discount rate of 10%. This amount is the same as the
standardized measure of discounted future net cash flows related to proved oil and natural gas reserves
except that it is determined without deducting future income taxes. Although PV 10 Value is not a
financial measure calculated in accordance with GAAP, management believes that the presentation of PV
10 Value is relevant and useful to our investors because it presents the discounted future net cash flows
attributable to our proved reserves prior to taking into account corporate future income taxes and our
current tax structure. We use this measure when assessing the potential return on investment related to our
oil and gas properties. Because many factors that are unique to any given company affect the amount of
estimated future income taxes, the use of a pre-tax measure is helpful to investors when comparing
companies in our industry.

“Proved developed reserves” means reserves that can be expected to be recovered through existing
wells with existing equipment and operating methods. Additional oil and gas expected to be obtained
through the application of fluid injection or other improved recovery techniques for supplementing the
natural forces and mechanisms of primary recovery will be included as “proved developed reserves” only
after testing by a pilot project or after the operation of an installed program has confirmed through
production response that increased recovery will be achieved.

“Proved developed non-producing” means reserves (i) expected to be recovered from zones
capable of producing but which are shut-in because no market outlet exists at the present time or whose
date of connection to a pipeline is uncertain or (ii) currently behind the pipe in existing wells, which are
considered proved by virtue of successful testing or production of offsetting wells.

“Proved developed producing” means reserves expected to be recovered from currently producing
zones under continuation of present operating methods. This category may also include recently
completed shut-in gas wells scheduled for connection to a pipeline in the near future.

“Proved reserves” means the estimated quantities of crude oil, natural gas, and natural gas liquids
which geological and engineering data demonstrate with reasonable certainty to be recoverable in future

4

years from known reservoirs under existing economic and operating conditions, i.e., prices and costs as of
the date the estimate is made. Prices include consideration of changes in existing prices provided only by
contractual arrangements, but not on escalations based upon future conditions.

“Proved undeveloped reserves” means reserves that are expected to be recovered from new wells
on undrilled acreage, or from existing wells where a relatively major expenditure is required for
recompletion. Reserves on undrilled acreage shall be limited to those drilling units offsetting productive
units that are reasonably certain of production when drilled. Proved reserves for other undrilled units can
be claimed only where it can be demonstrated with certainty that there is continuity of production from
the existing productive formation. Under no circumstances are estimates for proved undeveloped reserves
attributable to any acreage for which an application of fluid injection or other improved recovery
technique is contemplated, unless such techniques have been proved effective by actual tests in the area
and in the same reservoir.

“Recompletion” means the completion for production of an existing well bore in another formation

from which the well has been previously completed.

“Reserve life” means the calculation derived by dividing year-end reserves by total production in

that year.

“Reserve replacement” means the calculation derived by dividing additions to reserves from
acquisitions, extensions, discoveries and revisions of previous estimates in a year by total production in
that year.

“Royalty” means an interest in an oil and gas lease that gives the owner of the interest the right to
receive a portion of the production from the leased acreage (or of the proceeds of the sale thereof), but
generally does not require the owner to pay any portion of the costs of drilling or operating the wells on
the leased acreage. Royalties may be either landowner’s royalties, which are reserved by the owner of the
leased acreage at the time the lease is granted, or overriding royalties, which are usually reserved by an
owner of the leasehold in connection with a transfer to a subsequent owner.

“3-D seismic” means an advanced technology method of detecting accumulations of hydrocarbons
identified by the collection and measurement of the intensity and timing of sound waves transmitted into
the earth as they reflect back to the surface.

“Tcfe” means one trillion cubic feet of natural gas equivalent.

“Working interest” means an interest in an oil and gas lease that gives the owner of the interest the
right to drill for and produce oil and gas on the leased acreage and requires the owner to pay a share of the
costs of drilling and production operations. The share of production to which a working interest owner is
entitled will always be smaller than the share of costs that the working interest owner is required to bear,
with the balance of the production accruing to the owners of royalties. For example, the owner of a 100%
working interest in a lease burdened only by a landowner’s royalty of 12.5% would be required to pay
100% of the costs of a well but would be entitled to retain 87.5% of the production.

“Workover” means operations on a producing well to restore or increase production.

ITEMS 1. and 2. BUSINESS AND PROPERTIES

PART I

We are a Nevada corporation engaged in the acquisition, development, production and exploration of

oil and natural gas. Our common stock is listed and traded on the New York Stock Exchange.

Our oil and gas operations are concentrated in East Texas/North Louisiana, South Texas and
West Texas. Our oil and natural gas properties are estimated to have proved reserves of 711.9 Bcfe with
an estimated PV 10 Value of $1.0 billion as of December 31, 2012 and a standardized measure of
discounted future net cash flows of $0.8 billion. Our consolidated proved oil and natural gas reserve base
is 67% natural gas and 33% oil. Our proved reserves are 62% developed on a Bcfe basis as of
December 31, 2012.

Our proved reserves at December 31, 2012 and our 2012 average daily production are summarized

Strengths

High Quality Properties. Our operations are focused in three primary operating areas: East Texas/
North Louisiana, South Texas and West Texas. Our properties have an average reserve life of
approximately 7.4 years and have extensive development and exploration potential. In response to the
continuing low natural gas price environment, we have focused our drilling activity primarily on oil
projects. Our two primary properties that provide opportunities to increase our oil production and reserves
are our South Texas Eagle Ford shale properties and our Wolfbone field in West Texas. We have 34,727
acres (27,689 net to us) in the Eagle Ford shale and we have 88,666 acres (54,355 net to us) in West
Texas prospective in the Bone Spring and Wolfcamp shales. Our properties in the East Texas/North
Louisiana region, including 93,620 acres (80,046 net to us) in the Haynesville or Bossier shales, are
primarily prospective for natural gas.

Successful Exploration and Development Program.

In 2012 we spent $524.9 million, net of
reimbursed costs from our joint venture partner, on exploration and development activities. We drilled 85
wells (54.2 net to us) in 2012 at a cost of $415.1 million and we spent $70.9 million to complete 20 wells
(13.6 net to us) that were drilled in 2011. We also spent $35.1 million in 2012 to acquire additional
leasehold, $0.1 million to acquire seismic data and $3.7 million for recompletions, workovers,
abandonment and production facilities. 80% of our 2012 capital expenditures were directed towards oil
projects. Our drilling activities in 2012 added 22.5 MMBOE to our proved reserves and increased our oil
production by 175% from 2011.

Efficient Operator. We operated 90% of our proved oil and natural gas reserve base as of
December 31, 2012. As operator we are better able to control operating costs, the timing and plans for

6

future development, the level of drilling and lifting costs and the marketing of production. As an operator,
we receive reimbursements for overhead from other working interest owners, which reduces our general
and administrative expenses.

Successful Acquisitions. We have had significant growth over the years as a result of our
acquisition activity. We apply strict economic and reserve risk criteria in evaluating acquisitions. Over the
last twenty years, we have added 1.1 Tcfe of proved oil and natural gas reserves from 38 acquisitions at
an average cost of $1.17 per Mcfe. Our application of strict economic and reserve risk criteria have
enabled us to successfully evaluate and integrate acquisitions.

Business Strategy

Pursue Exploration Opportunities. We conduct exploration activities to grow our reserve base and
to replace our production each year. During 2012 we refocused our efforts on prospects with potential for
oil development, and we have limited our drilling on our natural gas properties due to the decline in
natural gas prices.

From 2010 through 2012 we spent approximately $155.2 million to acquire 34,727 acres (27,689 net
to us) in South Texas, which we believe to be prospective for oil in the Eagle Ford shale formation. In
2012, we spent approximately $201.7 million to drill 30 wells (20.5 net to us) on our Eagle Ford shale
properties. In 2012 we entered into a joint venture arrangement to allow us to accelerate the development
of our acreage. Our joint venture partner participates for a one-third interest in the wells that we drill in
exchange for paying $25,000 per net acre that is earned by their participation. In 2012, our Eagle Ford
shale drilling program added 13.2 MMBOE to our proved reserves. In 2013 we have budgeted to spend
$219.0 million, net of reimbursements from our joint venture partner, to drill 42 wells (27.3 net to us) on
our Eagle Ford shale properties and to complete six wells (3.8 net to us) that were drilled in 2012.

We have spent approximately $340.0 million to acquire 68,764 acres (41,071 net to us) in Reeves
County in West Texas, which we believe to be prospective for oil in the Bone Spring and Wolfcamp
shales in the Delaware Basin. During 2012 we spent $183.4 million and drilled 48 wells (30.5 net to us)
in West Texas. Our drilling program added 6.9 MMBOE to our reserves in 2012. In 2013 we have
budgeted $168.9 million to drill 33 wells (27.2 net to us), including eight horizontal Wolfcamp shale
wells (7.3 net to us).

We have a significant acreage position of 93,620 acres (80,046 net to us) in East Texas and North
Louisiana with Haynesville or Bossier shale natural gas potential but in 2012 we have deferred most of
our drilling operations due to the low natural gas price environment. In 2012, we drilled seven
Haynesville and Bossier shale horizontal wells (3.2 net to us) which added 14 Bcfe to our proved reserves
in 2012. With the low natural gas price outlook in 2013, we continue to defer our natural gas focused
drilling. We have budgeted to spend $32.1 million in 2013 to drill ten Haynesville and Bossier shale
horizontal wells (3.6 net to us).

Exploit Existing Reserves. We seek to maximize the value of our oil and gas properties by
increasing production and recoverable reserves through development drilling and workover, recompletion
including 3-D seismic data,
and exploitation activities. We utilize advanced industry technology,
horizontal drilling, improved logging tools, and formation stimulation techniques.

Maintain Flexible Capital Expenditure Budget. The timing of most of our capital expenditures is
discretionary because we have not made any significant long-term capital expenditure commitments
except for contracted drilling and completion services. We operate most of the drilling projects in which
we participate. Consequently, we have a significant degree of flexibility to adjust the level of such

7

expenditures according to market conditions. We have budgeted to spend approximately $420.0 million in
2013 on our development and exploration projects and $25.0 million for lease acquisition activity.

Acquire High Quality Properties at Attractive Costs. Historically, we have had a successful track
record of increasing our oil and natural gas reserves through opportunistic acquisitions. Over the
last twenty years, we have added 1.1 Tcfe of proved oil and natural gas reserves from 38 acquisitions at a
total cost of $1.3 billion, or $1.17 per Mcfe. The acquisitions were acquired at an average of 67% of their
PV 10 Value in the year the acquisitions were completed. In evaluating acquisitions, we apply strict
economic and reserve risk criteria. We target properties in our core operating areas with established
production and low operating costs that also have potential opportunities to increase production and
reserves through exploration and exploitation activities. We also evaluate our existing properties and
consider divesting of non-strategic assets when market conditions are favorable.

East Texas/North Louisiana Region

Approximately 48% or 341.9 Bcfe of our proved reserves are located in East Texas and
North Louisiana where we own interests in 958 producing wells (585.8 net to us) in 28 field areas. We
operate 664 of these wells. The largest of our fields in this region are the Logansport, Toledo Bend,
Beckville, Waskom, Blocker, Mansfield, Darco and Douglass fields. Production from this region
averaged 194 MMcf of natural gas per day and 220 barrels of oil per day during 2012 or 196 MMcfe per
day. Most of the reserves in this area produce from the upper Jurassic aged Haynesville or Bossier shale
or Cotton Valley formations and the Cretaceous aged Travis Peak/Hosston formation. In 2012, we spent
$101.1 million drilling seven wells (3.2 net to us) and completing 16 wells (10.4 net to us) that were
drilled in 2011. We also spent $8.2 million on leasehold costs and $1.7 million on workovers and
recompletions in this region. All seven of the wells we drilled in 2012 were horizontal wells that targeted
the Haynesville or Bossier shales. We plan to spend approximately $32.1 million in 2013 in this region to
drill ten (3.6 net to us) horizontal wells targeting the Haynesville or Bossier shales. These wells are
required to retain our interest in certain undeveloped leases.

Logansport

(1) The PV 10 Value represents the discounted future net cash flows attributable to our proved oil and natural gas reserves before income tax, discounted at 10%. Although it is a non-GAAP
measure, we believe that the presentation of the PV 10 Value is relevant and useful to our investors because it presents the discounted future net cash flows attributable to our proved
reserves prior to taking into account corporate future income taxes and our current tax structure. We use this measure when assessing the potential return on investment related to our oil and
gas properties. The standardized measure of discounted future net cash flows represents the present value of future cash flows attributable to our proved oil and natural gas reserves after
income tax, discounted at 10%.

Proved reserves that are attributable to existing producing wells are primarily determined using
decline curve analysis and rate transient analysis, which incorporates the principles of hydrocarbon flow.
Proved reserves attributable to producing wells with limited production history and for undeveloped
locations are estimated using performance from analogous wells in the surrounding area and geologic
data to assess the reservoir continuity. Technologies relied on to establish reasonable certainty of
economic producibility include, but are not limited to, electrical logs, radioactivity logs, core analyses,
geologic maps and available production data, seismic data and well test data.

There are numerous uncertainties inherent in estimating quantities of proved oil and natural gas
reserves. Oil and natural gas reserve engineering is a subjective process of estimating underground
accumulations of oil and natural gas that cannot be precisely measured. The accuracy of any reserve
estimate is a function of the quality of available data and of engineering and geological interpretation and
judgment. Results of drilling, testing and production subsequent to the date of the estimate may justify
revision of such estimate. Accordingly, reserves estimates are often different from the quantities of oil
and natural gas that are ultimately recovered.

Reserves may be classified as proved undeveloped if there is a high degree of confidence that the
quantities will be recovered, and they are scheduled to be drilled within five years of their initial inclusion
as proved reserves, unless specific circumstances justify a longer time. In connection with estimating
proved undeveloped reserves for our December 31, 2012 reserve report, reserves on undrilled acreage
were limited to those directly offsetting development spacing areas that are reasonably certain of
production when drilled. Using empirical evidence, we utilize control points and sample sizes to show
continuity in the reservoir.

Our oil proved undeveloped reserves increased by 3.2 MMBbls during 2012. This increase was
primarily due to our drilling program which added 8.1 MMBbls in the Eagle Ford shale and 2.4 MMBbls
in West Texas. We also sold 5.7 million barrels of proved undeveloped oil reserves, and converted
1.6 million barrels to developed in 2012.

Our natural gas proved undeveloped reserves decreased by 460 Bcf at December 31, 2012 as
compared with December 31, 2011. This decrease was primarily related to the decline in natural gas
prices, which caused approximately 465 Bcf of our natural gas proved undeveloped reserves to become
uneconomic under the natural gas price used to determine proved reserves in 2012. We also sold 22 Bcf
of natural gas proved undeveloped reserves, added 11 Bcf of natural gas proved undeveloped reserves
from our drilling program, and had other revisions of 16 Bcf. Included in the 465 Bcf of reserves
reductions associated with downward price revisions were 330 Bcf of proved undeveloped natural gas
reserves that, as of December 31, 2011 had positive undiscounted future cash flows but had a rate of
return that was less than 10%. These reserves became uneconomic due to the lower natural gas prices
used to determine our 2012 year end reserve estimates.

As of December 31, 2012, our proved undeveloped reserves included 26.9 MMBbls of oil and 107.8
Bcf of natural gas, for a total of 269.3 Bcfe of undeveloped reserves. Approximately 16.4 MMBbls of oil
and 33 Bcf of natural gas of our proved undeveloped reserves at December 31, 2012 were associated with
the future development of our West Texas properties that we acquired in December 2011 and an
additional 10.5 MMBbls of oil and 7 Bcf of natural gas were associated with our Eagle Ford shale
properties in South Texas. The proved undeveloped reserves associated with our Haynesville or Bossier
shale properties represented approximately 55 Bcf of our natural gas proved undeveloped reserves at
December 31, 2012. The remaining proved undeveloped reserves are primarily associated with
developing reserves in our Cotton Valley and Hosston sand reservoirs in East Texas/North Louisiana and
the Wilcox and Vicksburg reservoirs in South Texas. In 2012, we focused on drilling oil properties due to
the weak natural gas prices. Seven of the Eagle Ford shale wells and four of the Wolfbone shale oil wells
we drilled in 2012 resulted in conversions of proved undeveloped reserves to proved developed producing
reserves at December 31, 2012. Undeveloped natural gas reserves originally expected to be converted to
developed reserves in 2012 were removed from our proved reserves due to the low natural gas prices
during 2012.

16

Our oil proved undeveloped reserves increased by 22.4 MMBbls during 2011. This increase was
primarily due to our acquisition of proved undeveloped reserves in West Texas of 17.0 MMBbls, proved
undeveloped reserves additions of 4.7 MMBbls from our Eagle Ford shale properties and 0.7 MMBbls of
oil additions and revisions on our other properties. Our natural gas proved undeveloped reserves increased
by 49 Bcf during 2011. This increase was primarily related to our successful Haynesville and Bossier
shale drilling program which added 44 Bcf of natural gas reserves, our acquisition in West Texas which
added 34 Bcf and we had other additions of approximately 36 Bcf. Our proved undeveloped natural gas
reserves additions were partially offset by conversions to proved developed reserves of approximately 40
Bcf during 2011 and other downward revisions to previous estimates of approximately 23 Bcf.

As of December 31, 2011, our proved undeveloped reserves included 23.7 MMBbls of oil and 568
Bcf of natural gas, for a total of 710 Bcfe of undeveloped reserves. Approximately 17.0 MMBbls of oil
and 34 Bcf of natural gas of our proved undeveloped reserves at December 31, 2011 were associated with
the future development of our West Texas properties that we acquired in December 2011 and an
additional 6.0 MMBbls of oil and 5 Bcf of natural gas were associated with our Eagle Ford shale
properties in South Texas. The proved undeveloped natural gas reserves associated with our Haynesville
or Bossier shale properties represented approximately 425 Bcf of our total natural gas proved
undeveloped reserves at December 31, 2011. The remaining proved undeveloped reserves are primarily
associated with developing reserves in our Cotton Valley and Hosston sand reservoirs in East Texas/
North Louisiana and our Wilcox and Vicksburg reservoirs in South Texas. During the year ended
December 31, 2011, the price of oil increased significantly, and the value of oil relative to natural gas on
a heating equivalent basis widened to historic levels. This, coupled with a growing over-supply of natural
gas in the United States, caused us to change our strategic focus towards oil and away from natural gas.
As a result, our drilling program during 2011, which was initially focused on our Haynesville and Bossier
shale reserves, was refocused during the year towards our oil prone properties in the Eagle Ford shale in
South Texas. Eleven of the Haynesville shale wells we drilled in 2011 resulted in conversions of proved
undeveloped reserves to proved developed producing reserves at the end of 2011. To better position the
company for future growth of oil production, in late 2011 we acquired a substantial acreage position in
West Texas which is prospective for oil. A portion of this acquisition was determined to contain proved
undeveloped reserves.

Our estimates of oil and natural gas reserves at December 31, 2012 include 80.6 Bcfe related to
undrilled wells that have positive undiscounted future cash flows but which, based upon oil and natural
gas prices that we use to prepare the proved reserve estimates, have a rate of return that is less than the
10% discount rate used in the Standardized Measure of Discounted Future Cash Flows attributable to the
proved reserve estimates. We intend to drill the proved undeveloped wells in the time frame reflected in
the estimates of proved oil and natural gas reserves as of December 31, 2012 based upon the oil and
natural gas prices that we used to prepare the reserve estimates. We anticipate drilling such proved
undeveloped locations based on our current development plans for our properties. Certain of these wells
may be drilled to retain leasehold interests or to properly manage reservoir performance. To the extent
that actual oil or natural gas prices are substantially weaker, we may have to modify our development
plans or we may not fully recover our investment in drilling these wells from future cash flows.

Our estimated future capital costs to develop proved undeveloped reserves as of December 31, 2012
of $1.1 billion decreased by $0.9 billion from our estimated future capital costs of $2.0 billion as of
December 31, 2011. During 2012 we incurred approximately $87.3 million to develop proved
undeveloped reserves, primarily in our Eagle Ford shale and West Texas properties. Our oil focused
future capital expenditures increased by $155.0 million and our natural gas focused capital expenditures
decreased by $955.0 million. Approximately $749.0 million of the reduction in our estimated future
development costs in 2012 was associated with wells that, as of December 31, 2011, had positive
undiscounted cash flows but had a rate of return of less than 10%.

Our estimated future capital costs to develop proved undeveloped reserves as of December 31, 2011
of $2.0 billion increased by $858.0 million from our estimated future capital costs of $1.1 billion as of
December 31, 2010. During 2011, we incurred approximately $56.3 million to develop proved
undeveloped reserves in our Haynesville shale properties. Due to the success of our oil focused drilling

18

programs, we increased our proved undeveloped reserve estimates in the Eagle Ford shale and we
acquired properties in West Texas with significant potential for oil during 2011. During 2011 our oil
focused future capital expenditures increased by $169.0 million in the Eagle Ford shale and
$654.0 million in West Texas. Our future capital expenditures in the Haynesville and Bossier shales
increased by $244.0 million during 2011 reflecting our 2011 drilling success on these properties, while
we further reduced our forecast of capital expenditures on our remaining conventional natural gas
undeveloped reserves by $151.0 million during 2011.

The estimates of our oil and natural gas reserves were determined by Lee Keeling and Associates,
Inc. (“Lee Keeling”), an independent petroleum engineering firm. Lee Keeling has been providing
consulting engineering and geological services for over fifty years. Lee Keeling’s professional staff is
comprised of qualified petroleum engineers who are experienced in all productive areas of the
United States. The technical person responsible for review of our reserve estimates at Lee Keeling meets
the requirements regarding qualifications, independence, objectivity and confidentiality set forth in the
Standards Pertaining to Estimating and Auditing of Oil and Gas Reserves Information promulgated by the
Society of Petroleum Engineers. Lee Keeling does not own any interests in our properties and is not
employed on a contingent fee basis.

We have established, and maintain, internal controls designed to provide reasonable assurance that
the estimates of proved reserves are computed and reported in accordance with rules and regulations
promulgated by the SEC. These internal controls include documented process workflows, employing
qualified professional engineering and geological personnel, and on-going education for personnel
involved in our reserves estimation process. Our internal audit function routinely tests our processes and
controls. Inputs to our reserves estimation process, which we provide to Lee Keeling for use in their
reserves evaluation, are based upon our historical results for production history, oil and natural gas prices,
lifting and development costs, ownership interests and other required data. Our Reservoir Engineering
Department, comprised of qualified petroleum engineers and technical support staff, works with our
operating, accounting, land and marketing departments in order to accumulate the information required
for the reserves estimation process. Our Vice President of Reservoir Engineering is the primary person in
charge of overseeing our reserve estimates and our Reservoir Engineering Department. He has a BS
Degree and a Masters Degree in Petroleum Engineering, is a Registered Professional Engineer and has
over thirty-five years of experience in various technical roles within the oil and gas industry. During the
reserves estimation process our petroleum engineers work with Lee Keeling to ensure that all data we
provide is properly reflected in the final reserves estimates and they consult with Lee Keeling throughout
the reserves estimation process on technical questions regarding the reserve estimates. We also regularly
communicate with Lee Keeling throughout the year about our operations and the potential impact of
operational changes and events on our reserve estimates.

We did not provide estimates of total proved oil and natural gas reserves during the years ended

December 31, 2010, 2011 or 2012 to any federal authority or agency, other than the SEC.

Title to our oil and natural gas properties is subject to royalty, overriding royalty, carried and other
similar interests and contractual arrangements customary in the oil and gas industry, liens incident to
operating agreements and for current taxes not yet due and other minor encumbrances. All of our oil and
natural gas properties are pledged as collateral under our bank credit facility. As is customary in the oil
and gas industry, we are generally able to retain our ownership interest in undeveloped acreage by
production of existing wells, by drilling activity which establishes commercial reserves sufficient to
maintain the lease, by payment of delay rentals or by the exercise of contractual extension rights. The
Company anticipates retaining ownership of a substantial amount of the acreage with primary terms
expiring in 2013 through drilling activity or by extending the leases.

Markets and Customers

The market for oil and natural gas produced by us depends on factors beyond our control, including
the extent of domestic production and imports of oil and natural gas, the proximity and capacity of natural
gas pipelines and other transportation facilities, demand for oil and natural gas, the marketing of
competitive fuels and the effects of state and federal regulation. The oil and gas industry also competes
with other industries in supplying the energy and fuel requirements of industrial, commercial and
individual consumers.

Our oil production is currently sold under short-term contracts with a duration of six months or less.
The contracts require the purchasers to purchase the amount of oil production that is available at prices

21

tied to the spot oil markets. Our natural gas production is primarily sold under contracts with various
terms and priced on first of the month index prices or on daily spot market prices. Approximately 89% of
our 2012 natural gas sales were priced utilizing first of the month index prices and approximately 11%
were priced utilizing daily spot prices. BP Energy Company and its subsidiaries and Shell Oil Company
and its subsidiaries accounted for 42% and 27%, respectively, of our total 2012 sales. The loss of either of
these customers would not have a material adverse effect on us as there is an available market for our
crude oil and natural gas production from other purchasers.

We have entered into longer term marketing arrangements to ensure that we have adequate
transportation to get our natural gas production in North Louisiana to the markets. As an alternative to
constructing our own gathering and treating facilities, we have entered into a variety of gathering and
treating agreements with midstream companies to transport our natural gas to the long-haul natural gas
pipelines. We have entered into certain agreements with a major natural gas marketing company to
provide us with firm transportation for 80,000 MMBtus per day for our North Louisiana natural gas
production on the long-haul pipelines. These agreements expire from 2013 to 2019. To the extent we are
not able to deliver the contracted natural gas volumes, we may be responsible for the transportation costs.
Our production available to deliver under these agreements in North Louisiana is expected to exceed the
firm transportation arrangements we have in place. In addition, the marketing company managing the
firm transportation is required to use reasonable efforts to supplement our deliveries should we have a
shortfall during the term of the agreements.

Competition

The oil and gas industry is highly competitive. Competitors include major oil companies, other
independent energy companies and individual producers and operators, many of which have financial
resources, personnel and facilities substantially greater than we do. We face intense competition for the
acquisition of oil and natural gas properties and leases for oil and gas exploration.

Regulation

General. Various aspects of our oil and natural gas operations are subject

to extensive and
continually changing regulation, as legislation affecting the oil and natural gas industry is under constant
review for amendment or expansion. Numerous departments and agencies, both federal and state, are
authorized by statute to issue, and have issued, rules and regulations binding upon the oil and natural gas
industry and its individual members. The Federal Energy Regulatory Commission, or “FERC,” regulates
the transportation and sale for resale of natural gas in interstate commerce pursuant to the Natural Gas Act
of 1938, or “NGA,” and the Natural Gas Policy Act of 1978, or “NGPA.” In 1989, however, Congress
enacted the Natural Gas Wellhead Decontrol Act, which removed all remaining price and nonprice
controls affecting all “first sales” of natural gas, effective January 1, 1993, subject to the terms of any
private contracts that may be in effect. While sales by producers of natural gas and all sales of crude oil,
condensate and natural gas liquids can currently be made at uncontrolled market prices, in the future
Congress could reenact price controls or enact other legislation with detrimental impact on many aspects
of our business. Under the provisions of the Energy Policy Act of 2005 (the “2005 Act”), the NGA has
been amended to prohibit any form of market manipulation with the purchase or sale of natural gas, and
the FERC has issued new regulations that are intended to increase natural gas pricing transparency. The
2005 Act has also significantly increased the penalties for violations of the NGA. The FERC has issued
Order No. 704 et al. which requires a market participant to make an annual filing if it has sales or
purchases equal
to or greater than 2.2 million MMBtu in the reporting year to facilitate price
transparency.

22

Regulation and transportation of natural gas. Our sales of natural gas are affected by the
availability, terms and cost of transportation. The price and terms for access to pipeline transportation are
subject
to extensive regulation. The FERC requires interstate pipelines to provide open-access
transportation on a not unduly discriminatory basis for similarly situated shippers. The FERC frequently
reviews and modifies its regulations regarding the transportation of natural gas, with the stated goal of
fostering competition within the natural gas industry.

Intrastate natural gas transportation is subject to regulation by state regulatory agencies. The Texas
Railroad Commission has been changing its regulations governing transportation and gathering services
provided by intrastate pipelines and gatherers. While the changes by these state regulators affect us only
indirectly, they are intended to further enhance competition in natural gas markets. We cannot predict
what further action the FERC or state regulators will take on these matters; however, we do not believe
that we will be affected differently in any material respect than other natural gas producers with which we
compete by any action taken.

Additional proposals and proceedings that might affect the natural gas industry are pending before
Congress, the FERC, state commissions and the courts. The natural gas industry historically has been
very heavily regulated; therefore, there is no assurance that the less stringent regulatory approach pursued
by the FERC, Congress and state regulatory authorities will continue.

Federal leases. Some of our operations are located on federal oil and natural gas leases that are
administered by the Bureau of Land Management (“BLM”) of the United States Department of the
Interior. These leases are issued through competitive bidding and contain relatively standardized terms.
These leases require compliance with detailed Department of Interior and BLM regulations and orders
that are subject to interpretation and change. These leases are also subject to certain regulations and
orders promulgated by the Department of Interior’s Bureau of Ocean Energy Management, Regulation &
Enforcement (“BOEMRE”), through its Minerals Revenue Management Program, which is responsible
for the management of revenues from both onshore and offshore leases.

Oil and natural gas liquids transportation rates. Our sales of crude oil, condensate and natural gas
liquids are not currently regulated and are made at market prices. In a number of instances, however, the
ability to transport and sell such products is dependent on pipelines whose rates, terms and conditions of
service are subject to FERC jurisdiction under the Interstate Commerce Act. In other instances, the ability
to transport and sell such products is dependent on pipelines whose rates, terms and conditions of service
are subject to regulation by state regulatory bodies under state statutes. The price received from the sale
of these products may be affected by the cost of transporting the products to market.

The FERC’s regulation of pipelines that transport crude oil, condensate and natural gas liquids under
the Interstate Commerce Act is generally more light-handed than the FERC’s regulation of natural gas
pipelines under the NGA. FERC-regulated pipelines that transport crude oil, condensate and natural gas
liquids are subject to common carrier obligations that generally ensure non-discriminatory access. With
respect to interstate pipeline transportation subject to regulation of the FERC under the Interstate
Commerce Act, rates generally must be cost-based, although settlement rates agreed to by all shippers are
permitted and market-based rates are permitted in certain circumstances. Effective January 1, 1995, the
FERC implemented regulations establishing an indexing system (based on inflation) for transportation
rates governed by the Interstate Commerce Act
that allowed for an increase or decrease in the
transportation rates. The FERC’s regulations include a methodology for such pipelines to change their
rates through the use of an index system that establishes ceiling levels for such rates. The mandatory
five year review in 2005 revised the methodology for this index to be based on Producer Price Index for
Finished Goods (PPI-FG) plus 1.3 percent for the period July 1, 2006 through June 30, 2012. The
mandatory five year review in 2012 revised the methodology for this index to be based on PPI-FG plus

23

2.65 percent for the period July 1, 2012 through June 30, 2016. The regulations provide that each year the
Commission will publish the oil pipeline index after the PPI-FG becomes available.

With respect to intrastate crude oil, condensate and natural gas liquids pipelines subject to the
jurisdiction of state agencies, such state regulation is generally less rigorous than the regulation of
interstate pipelines. State agencies have generally not investigated or challenged existing or proposed
rates in the absence of shipper complaints or protests. Complaints or protests have been infrequent and are
usually resolved informally.

We do not believe that the regulatory decisions or activities relating to interstate or intrastate crude
oil, condensate or natural gas liquids pipelines will affect us in a way that materially differs from the way
it affects other crude oil, condensate and natural gas liquids producers or marketers.

Environmental regulations. We are subject to stringent federal, state and local laws. These laws,
among other things, govern the issuance of permits to conduct exploration, drilling and production
operations, the amounts and types of materials that may be released into the environment, the discharge
and disposition of waste materials, the remediation of contaminated sites and the reclamation and
abandonment of wells, sites and facilities. Numerous governmental departments issue rules and
regulations to implement and enforce such laws, which are often difficult and costly to comply with and
which carry substantial civil and even criminal penalties for failure to comply. Some laws, rules and
regulations relating to protection of the environment may, in certain circumstances, impose strict liability
for environmental contamination, rendering a person liable for environmental damages and cleanup cost
without regard to negligence or fault on the part of such person. Other laws, rules and regulations may
restrict the rate of oil and natural gas production below the rate that would otherwise exist or even
prohibit exploration and production activities in sensitive areas. In addition, state laws often require
various forms of remedial action to prevent pollution, such as closure of inactive pits and plugging of
abandoned wells. The regulatory burden on the oil and natural gas industry increases our cost of doing
business and consequently affects our profitability. These costs are considered a normal, recurring cost of
to the same laws and
our on-going operations. Our domestic competitors are generally subject
regulations.

We believe that we are in substantial compliance with current applicable environmental laws and
regulations and that continued compliance with existing requirements will not have a material adverse
impact on our operations. However, environmental laws and regulations have been subject to frequent
changes over the years, and the imposition of more stringent requirements or new regulatory schemes
such as carbon “cap and trade” programs could have a material adverse effect upon our capital
expenditures, earnings or competitive position, including the suspension or cessation of operations in
affected areas. As such, there can be no assurance that material cost and liabilities will not be incurred in
the future.

The Comprehensive Environmental Response, Compensation and Liability Act, or “CERCLA,”
imposes liability, without regard to fault, on certain classes of persons that are considered to be
responsible for the release of a “hazardous substance” into the environment. These persons include the
current or former owner or operator of the disposal site or sites where the release occurred and companies
that disposed or arranged for the disposal of hazardous substances. Under CERCLA, such persons may be
subject to joint and several liability for the cost of investigating and cleaning up hazardous substances that
have been released into the environment, for damages to natural resources and for the cost of certain
health studies. In addition, companies that incur liability frequently also confront third party claims
because it is not uncommon for neighboring landowners and other third parties to file claims for personal
injury and property damage allegedly caused by hazardous substances or other pollutants released into the
environment from a polluted site.

transportation, storage,

The Federal Solid Waste Disposal Act, as amended by the Resource Conservation and Recovery Act
treatment and disposal of
of 1976, or “RCRA,” regulates the generation,
hazardous wastes and can require cleanup of hazardous waste disposal sites. RCRA currently excludes
drilling fluids, produced waters and other wastes associated with the exploration, development or
production of oil and natural gas from regulation as “hazardous waste.” Disposal of such non-hazardous
oil and natural gas exploration, development and production wastes usually are regulated by state law.
Other wastes handled at exploration and production sites or used in the course of providing well services
may not fall within this exclusion. Moreover, stricter standards for waste handling and disposal may be
imposed on the oil and natural gas industry in the future. From time to time, legislation is proposed in
Congress that would revoke or alter the current exclusion of exploration, development and production
wastes from RCRA’s definition of “hazardous wastes,” thereby potentially subjecting such wastes to
more stringent handling, disposal and cleanup requirements. If such legislation were enacted, it could
have a significant impact on our operating costs, as well as the oil and natural gas industry in general. The
impact of future revisions to environmental laws and regulations cannot be predicted.

Our operations are also subject to the Clean Air Act, or “CAA,” and comparable state and local
requirements. Amendments to the CAA were adopted in 1990 and contain provisions that may result in the
gradual imposition of certain pollution control requirements with respect to air emissions from our
operations. On April 17, 2012, the U. S. Environmental Protection Agency or “EPA” promulgated new
emission standards for the oil and gas industry. These rules require a nearly 95 percent reduction in volatile
organic compounds (“VOCs”) emitted from hydraulically fractured gas wells by January 1, 2015. This
significant reduction in emissions is to be accomplished primarily through the use of “green completions”
(i.e., capturing natural gas that currently escapes to the air). These rules also have notification and reporting
requirements. Storage tanks emitting certain levels of VOCs may also require a 95% reduction of VOC
emissions by October 1, 2015. We may be required to incur certain capital expenditures in the future for air
pollution control equipment in connection with obtaining and maintaining operating permits and approvals
for air emissions. However, we believe our operations will not be materially adversely affected by any such
requirements, and the requirements are not expected to be any more burdensome to us than to other
similarly situated companies involved in oil and natural gas exploration and production activities.

The Federal Water Pollution Control Act of 1972, as amended, or the “Clean Water Act,” imposes
restrictions and controls on the discharge of produced waters and other wastes into navigable waters.
Permits must be obtained to discharge pollutants into state and federal waters and to conduct construction
activities in waters and wetlands. Certain state regulations and the general permits issued under the
Federal National Pollutant Discharge Elimination System program prohibit the discharge of produced
waters and sand, drilling fluids, drill cuttings and certain other substances related to the oil and natural gas
industry into certain coastal and offshore waters, unless otherwise authorized. Further, the EPA has
adopted regulations requiring certain oil and natural gas exploration and production facilities to obtain
permits for storm water discharges. Costs may be associated with the treatment of wastewater or
developing and implementing storm water pollution prevention plans. The Clean Water Act and
comparable state statutes provide for civil, criminal and administrative penalties for unauthorized
discharges for oil and other pollutants and impose liability on parties responsible for those discharges for
the cost of cleaning up any environmental damage caused by the release and for natural resource damages
resulting from the release. We believe that our operations comply in all material respects with the
requirements of the Clean Water Act and state statutes enacted to control water pollution.

The Federal Safe Drinking Water Act of 1974, as amended, requires EPA to develop minimum
federal requirements for Underground Injection Control (“UIC”) programs and other safeguards to protect
public health by preventing injection wells from contaminating underground sources of drinking water.
The UIC program does not regulate wells that are solely used for production. However, EPA has
authority to regulate hydraulic fracturing when diesel fuels are used in fluids or propping agents. In 2012,

25

EPA issued draft guidance on when UIC permitting requirements apply to fracking fluids containing
diesel. We are not able to predict at this time the effect on our operations should EPA require UIC permits
be obtained prior to utilizing diesel as a fracking agent. However, we believe our operations will not be
materially adversely affected by any such requirements, and the requirements are not expected to be any
more burdensome to us than to other similarly situated companies involved in oil and natural gas
exploration and production activities.

Federal regulators require certain owners or operators of facilities that store or otherwise handle oil
to prepare and implement spill prevention, control, countermeasure and response plans relating to the
possible discharge of oil into surface waters. The Oil Pollution Act of 1990 (“OPA”) contains numerous
requirements relating to the prevention and response to oil spills in the waters of the United States. The
OPA subjects owners of facilities to strict joint and several liability for all containment and cleanup costs
and certain other damages relating to a spill. Noncompliance with OPA may result in varying civil and
criminal penalties and liabilities.

Executive Order 13158, issued on May 26, 2000, directs federal agencies to safeguard existing
Marine Protected Areas, or “MPAs,” in the United States and establish new MPAs. The order requires
federal agencies to avoid harm to MPAs to the extent permitted by law and to the maximum extent
practicable. It also directs the EPA to propose new regulations under the Clean Water Act to ensure
appropriate levels of protection for the marine environment. This order has the potential to adversely
affect our operations by restricting areas in which we may carry out future exploration and development
projects and/or causing us to incur increased operating expenses.

Certain flora and fauna that have officially been classified as “threatened” or “endangered” are
protected by the Endangered Species Act. This law prohibits any activities that could “take” a protected
plant or animal or reduce or degrade its habitat area. If endangered species are located in an area we wish
to develop, the work could be prohibited or delayed and/or expensive mitigation might be required.

Other statutes that provide protection to animal and plant species and which may apply to our
operations include, but are not necessarily limited to, the Oil Pollution Act, the Emergency Planning and
Community Right to Know Act, the Marine Mammal Protection Act, the Marine Protection, Research and
Sanctuaries Act, the Fish and Wildlife Coordination Act, the Fishery Conservation and Management Act,
the Migratory Bird Treaty Act and the National Historic Preservation Act. These laws and regulations
may require the acquisition of a permit or other authorization before construction or drilling commences
and may limit or prohibit construction, drilling and other activities on certain lands lying within
wilderness or wetlands and other protected areas and impose substantial liabilities for pollution resulting
to revocation,
from our operations. The permits required for our various operations are subject
modification and renewal by issuing authorities. In addition, laws such as the National Environmental
Policy Act and the Coastal Zone Management Act may make the process of obtaining certain permits
more difficult or time consuming, resulting in increased costs and potential delays that could affect the
viability or profitability of certain activities.

Certain statutes such as the Emergency Planning and Community Right to Know Act require the
reporting of hazardous chemicals manufactured, processed, or otherwise used, which may lead to
heightened scrutiny of the company’s operations by regulatory agencies or the public. In 2012, the EPA
adopted a new reporting requirement, the Petroleum and Natural Gas Systems Greenhouse Gas Reporting
Rule (40 C.F.R. Part 98, Subpart W), which requires certain onshore petroleum and natural gas facilities
to begin collecting data on their emissions of greenhouse gases (“GHGs”) in January 2012, with the first
annual reports of those emissions due on September 28, 2012. GHGs include gases such as methane, a
primary component of natural gas, and carbon dioxide, a byproduct of burning natural gas. Different
GHGs have different global warming potentials with CO2 having the lowest global warming potential, so

26

emissions of GHGs are typically expressed in terms of CO2 equivalents, or CO2e. The rule applies to
facilities that emit 25,000 metric tons of CO2e or more per year, and requires onshore petroleum and
natural gas operators to group all equipment under common ownership or control within a single
hydrocarbon basin together when determining if the threshold is met. We have determined that these new
reporting requirements apply to us and we believe we have met all of the EPA required reporting
deadlines and strive to ensure accurate and consistent emissions data reporting. Other EPA actions with
respect to the reduction of greenhouse gases (such as EPA’s Greenhouse Gas Endangerment Finding,
EPA’s Prevention of Significant Deterioration and Title V Greenhouse Gas Tailoring Rule) and various
state actions have or could impose mandatory reductions in greenhouse gas emissions. We are unable to
predict at this time how much the cost of compliance with any legislation or regulation of greenhouse gas
emissions will be in future periods.

Such changes in environmental laws and regulations which result in more stringent and costly
reporting, or waste handling, storage, transportation, disposal or cleanup activities, could materially affect
companies operating in the energy industry. Adoption of new regulations further regulating emissions
from oil and gas production could adversely affect our business, financial position, results of operations
and prospects, as could the adoption of new laws or regulations which levy taxes or other costs on
greenhouse gas emissions from other industries, which could result in changes to the consumption and
demand for natural gas. We may also be assessed administrative, civil and/or criminal penalties if we fail
to comply with any such new laws and regulations applicable to oil and natural gas production.

We maintain insurance against “sudden and accidental” occurrences, which may cover some, but not
all, of the risks described above. Most significantly, the insurance we maintain will not cover the risks
described above which occur over a sustained period of time. Further, there can be no assurance that such
insurance will continue to be available to cover all such cost or that such insurance will be available at a
cost that would justify its purchase. The occurrence of a significant event not fully insured or indemnified
against could have a material adverse effect on our financial condition and results of operations.

Regulation of oil and natural gas exploration and production. Our exploration and production
operations are subject to various types of regulation at the federal, state and local levels. Such regulations
include requiring permits and drilling bonds for the drilling of wells, regulating the location of wells, the
method of drilling and casing wells and the surface use and restoration of properties upon which wells are
drilled. Many states also have statutes or regulations addressing conservation matters,
including
provisions for the unitization or pooling of oil and natural gas properties, the establishment of maximum
rates of production from oil and natural gas wells and the regulation of spacing, plugging and
abandonment of such wells. Some state statutes limit the rate at which oil and natural gas can be produced
from our properties.

State regulation. Most states regulate the production and sale of oil and natural gas, including
requirements for obtaining drilling permits, the method of developing new fields, the spacing and
operation of wells and the prevention of waste of oil and gas resources. The rate of production may be
regulated and the maximum daily production allowable from both oil and gas wells may be established on
a market demand or conservation basis or both.

ITEM 1A. RISK FACTORS

You should carefully consider the following risk factors as well as the other information contained or
incorporated by reference in this report, as these important factors, among others, could cause our actual
results to differ from our expected or historical results. It is not possible to predict or identify all such
factors. Consequently, you should not consider any such list to be a complete statement of all of our
potential risks or uncertainties.

A substantial or extended decline in oil and natural gas prices may adversely affect our business,
financial condition, cash flow, liquidity or results of operations and our ability to meet our capital
expenditure obligations and financial commitments and to implement our business strategy.

Our business is heavily dependent upon the prices of, and demand for, oil and natural gas.
Historically, the prices for oil and natural gas have been volatile and are likely to remain volatile in the
future. Prices for oil remained relatively strong in 2012, but our realized natural gas prices continued to
decline in 2012, reaching a thirteen year low of $2.03 per Mcf in the second quarter of 2012. The
continued growth in production of natural gas in the United States has increased supply and resulted in
high natural gas storage inventories. As a result, natural gas prices continue to face downward pressures.

The prices we receive for our oil and natural gas production and the level of such production will be
subject to wide fluctuations and depend on numerous factors beyond our control, including the following:

• the domestic and foreign supply of oil and natural gas;
• weather conditions;
• the price and quantity of imports of oil and natural gas;
• political conditions and events in other oil-producing and natural gas-producing countries,
including embargoes, hostilities in the Middle East and other sustained military campaigns, and
acts of terrorism or sabotage;

• the actions of the Organization of Petroleum Exporting Countries, or OPEC;
• domestic government regulation, legislation and policies;
• the level of global oil and natural gas inventories;
• technological advances affecting energy consumption;
• the price and availability of alternative fuels; and
• overall economic conditions.

31

If the decline in the price of natural gas that first started in 2008 continues through 2013, the lower

prices will adversely affect:

• our revenues, profitability and cash flow from operations;
• the value of our proved oil and natural gas reserves;
• the economic viability of certain of our drilling prospects;
• our borrowing capacity; and
• our ability to obtain additional capital.

We have entered into certain oil price hedging arrangements on certain of our anticipated sales in
2013. In the future we may enter into additional hedging arrangements in order to reduce our exposure to
price risks. Such arrangements would limit our ability to benefit from increases in oil and natural gas
prices.

The recent recession could have a material adverse impact on our financial position, results of
operations and cash flows.

The oil and gas industry is cyclical and tends to reflect general economic conditions. The
United States and other countries have been in a recession which could continue through 2013 and
beyond, and the capital markets have experienced significant volatility. The recession has had an adverse
impact on demand and pricing for oil and natural gas. A continuation of the recession could have a further
negative impact on oil and natural gas prices. Our operating cash flows and profitability will be
significantly affected by declining oil and natural gas prices. Further declines in oil and natural gas prices
may also impact the value of our oil and gas reserves, which could result in future impairment charges to
reduce the carrying value of our oil and gas properties and our marketable securities. Our future access to
capital could be limited due to tightening credit markets and volatile capital markets. If our access to
capital is limited, development of our assets may be delayed or limited, and we may not be able to
execute our growth strategy.

Our future production and revenues depend on our ability to replace our reserves.

Our future production and revenues depend upon our ability to find, develop or acquire additional oil
and natural gas reserves that are economically recoverable. Our proved reserves will generally decline as
reserves are depleted, except to the extent that we conduct successful exploration or development
activities or acquire properties containing proved reserves, or both. To increase reserves and production,
we must continue our acquisition and drilling activities. We cannot assure you, however, that our
acquisition and drilling activities will result in significant additional reserves or that we will have
continuing success drilling productive wells at low finding and development costs. Furthermore, while
our revenues may increase if prevailing oil and natural gas prices increase significantly, our finding costs
for additional reserves could also increase.

Prospects that we decide to drill may not yield oil or natural gas in commercially viable quantities or
quantities sufficient to meet our targeted rate of return.

A prospect is a property in which we own an interest or have operating rights and that has what our
geoscientists believe, based on available seismic and geological information, to be an indication of potential
oil or natural gas. Our prospects are in various stages of evaluation, ranging from a prospect that is ready to
be drilled to a prospect that will require substantial additional evaluation and interpretation. There is no way

32

to predict in advance of drilling and testing whether any particular prospect will yield oil or natural gas in
sufficient quantities to recover drilling or completion costs or to be economically viable. The use of seismic
data and other technologies and the study of producing fields in the same area will not enable us to know
conclusively prior to drilling whether oil or natural gas will be present or, if present, whether oil or natural
gas will be present in commercial quantities. The analysis that we perform using data from other wells,
more fully explored prospects and/or producing fields may not be useful in predicting the characteristics and
potential reserves associated with our drilling prospects. If we drill additional unsuccessful wells, our
drilling success rate may decline and we may not achieve our targeted rate of return.

Federal and state legislation and regulatory initiatives relating to hydraulic fracturing could
result in increased costs and additional operating restrictions or delays as well as restrict our access to
our oil and gas reserves.

Hydraulic fracturing is an essential and common practice that is used to stimulate production of oil
and natural gas from dense subsurface rock formations such as shale and tight sands. We routinely apply
hydraulic fracturing techniques in completing our wells. The process involves the injection of water, sand
and additives under pressure into a targeted subsurface formation. The water and pressure create fractures
in the rock formations, which are held open by the grains of sand, enabling the oil or natural gas to flow
to the wellbore. The use of hydraulic fracturing is necessary to produce commercial quantities of oil and
natural gas from many reservoirs including the Haynesville shale, Bossier shale, Eagle Ford shale,
Wolfcamp shale, Bone Spring, Cotton Valley and other tight natural gas and oil reservoirs. Substantially
all of our proved oil and gas reserves that are currently not producing and our undeveloped acreage
require hydraulic fracturing to be productive. All of the wells being drilled by us in 2013 utilize hydraulic
fracturing in their completion. We estimate we will incur approximately $178.0 million for hydraulic
fracturing services in connection with our 2013 drilling and completion program.

The use of hydraulic fracturing in our well completion activities could expose us to liability for
negative environmental effects that might occur. Although we have not had any incidents related to
hydraulic fracturing operations that we believe have caused any negative environmental effects, we have
established operating procedures to respond and report any unexpected fluid discharge which might occur
during our operations, including plans to remediate any spills that might occur. In the event that we were
to suffer a loss
insurance will be net of a
$25,000 deductible and our ability to recover costs will be limited to a total aggregate policy limit of
$26.0 million, which may or may not be sufficient to pay the full amount of our losses incurred.

related to hydraulic fracturing operations, our

Drilling and completion activities are typically regulated by state oil and natural gas commissions.
Our drilling and completion activities are conducted primarily in Louisiana and Texas. Texas adopted a
law in June 2012 requiring disclosure to the Railroad Commission of Texas and the public of certain
information regarding the components used in the hydraulic-fracturing process. Several proposals are
before the United States Congress that, if implemented, would subject the process of hydraulic fracturing
to regulation under the Safe Drinking Water Act. At the direction of Congress, the EPA is currently
conducting an extensive, multi-year study into the potential effects of hydraulic fracturing on
underground sources of drinking water, and the results of that study have the potential to impact the
likelihood or scope of future legislation or regulation.

Potential changes to US federal tax regulations, if passed, could have an adverse effect on us.

The United States Congress continues to consider imposing new taxes and repeal of many tax
incentives and deductions that are currently used by independent oil and gas producers. Examples of
changes being considered that would impact us are: elimination of the ability to fully deduct intangible

33

drilling costs in the year incurred, repeal of the manufacturing tax deduction for oil and gas companies,
increasing the geological and geophysical cost amortization period, and implementation of a fee on non-
producing leases located on federal lands. If these proposals are enacted, our current income tax liability
will increase, potentially significantly, which would have a negative impact on our cash flow from
operating activities. A reduction in operating cash flow could require us to reduce our drilling activities.
Since none of these proposals have yet to be included in new legislation, we do not know the ultimate
impact they may have on our business.

Our debt service requirements could adversely affect our operations and limit our growth.

We had $1.3 billion in debt as of December 31, 2012, and our ratio of total debt

to total

capitalization was approximately 59%.

Our outstanding debt will have important consequences, including, without limitation:

• a portion of our cash flow from operations will be required to make debt service payments;
• our ability to borrow additional amounts for working capital, capital expenditures (including

acquisitions) or other purposes will be limited; and

• our debt could limit our ability to capitalize on significant business opportunities, our flexibility in
planning for or reacting to changes in market conditions and our ability to withstand competitive
pressures and economic downturns.

In addition, future acquisition or development activities may require us to alter our capitalization
significantly. These changes in capitalization may significantly increase our debt. Moreover, our ability to
meet our debt service obligations and to reduce our total debt will be dependent upon our future
performance, which will be subject to general economic conditions and financial, business and other
factors affecting our operations, many of which are beyond our control. If we are unable to generate
sufficient cash flow from operations in the future to service our indebtedness and to meet other
commitments, we will be required to adopt one or more alternatives, such as refinancing or restructuring
our indebtedness, selling material assets or seeking to raise additional debt or equity capital. We cannot
assure you that any of these actions could be effected on a timely basis or on satisfactory terms or that
these actions would enable us to continue to satisfy our capital requirements.

Our bank credit facility contains a number of significant covenants. These covenants will limit our

ability to, among other things:

• borrow additional money;
• merge, consolidate or dispose of assets;
• make certain types of investments;
• enter into transactions with our affiliates; and
• pay dividends.

Our failure to comply with any of these covenants could cause a default under our bank credit
facility and the respective indentures governing our senior notes. A default, if not waived, could result in
acceleration of our indebtedness, in which case the debt would become immediately due and payable. If
this occurs, we may not be able to repay our debt or borrow sufficient funds to refinance it given the
current status of the credit markets. Even if new financing is available, it may not be on terms that are
acceptable to us. Complying with these covenants may cause us to take actions that we otherwise would
not take or not take actions that we otherwise would take.

34

The unavailability or high cost of drilling rigs, equipment, supplies or qualified personnel and
oilfield services could adversely affect our ability to execute our exploration and development plans
on a timely basis and within our budget.

Our industry has experienced a shortage of drilling rigs, equipment, supplies and qualified personnel
in recent years as the result of higher demand for these services. Costs and delivery times of rigs,
equipment and supplies have been substantially greater than they were several years ago. In addition,
demand for, and wage rates of, qualified drilling rig crews have escalated due to the higher activity levels.
Shortages of drilling rigs, equipment or supplies or qualified personnel in the areas in which we operate
could delay or restrict our exploration and development operations, which in turn could adversely affect
our financial condition and results of operations because of our concentration in those areas.

Our business involves many uncertainties and operating risks that can prevent us from realizing
profits and can cause substantial losses.

Our future success will depend on the success of our exploration and development activities.
Exploration activities involve numerous risks, including the risk that no commercially productive natural
gas or oil reserves will be discovered. In addition, these activities may be unsuccessful for many reasons,
including weather, cost overruns, equipment shortages and mechanical difficulties. Moreover,
the
successful drilling of a natural gas or oil well does not ensure we will realize a profit on our investment. A
variety of factors, both geological and market-related, can cause a well to become uneconomical or only
marginally economical. In addition to their costs, unsuccessful wells can hurt our efforts to replace
production and reserves.

Our business involves a variety of operating risks, including:

• unusual or unexpected geological formations;
• fires;
• explosions;
• blow-outs and surface cratering;
• uncontrollable flows of natural gas, oil and formation water;
• natural disasters, such as hurricanes, tropical storms and other adverse weather conditions;
• pipe, cement, or pipeline failures;
• casing collapses;
• mechanical difficulties, such as lost or stuck oil field drilling and service tools;
• abnormally pressured formations; and
• environmental hazards, such as natural gas leaks, oil spills, pipeline ruptures and discharges of

toxic gases.

If we experience any of these problems, well bores, gathering systems and processing facilities could

be affected, which could adversely affect our ability to conduct operations.

We could also incur substantial losses as a result of:

• injury or loss of life;
• severe damage to and destruction of property, natural resources and equipment;
• pollution and other environmental damage;
• clean-up responsibilities;
• regulatory investigation and penalties;
• suspension of our operations; and
• repairs to resume operations.

35

We pursue acquisitions as part of our growth strategy and there are risks in connection with
acquisitions.

Our growth has been attributable in part to acquisitions of producing properties and companies. We
expect to continue to evaluate and, where appropriate, pursue acquisition opportunities on terms we
consider favorable. However, we cannot assure you that suitable acquisition candidates will be identified
in the future, or that we will be able to finance such acquisitions on favorable terms. In addition, we
compete against other companies for acquisitions, and we cannot assure you that we will successfully
acquire any material property interests. Further, we cannot assure you that future acquisitions by us will
be integrated successfully into our operations or will increase our profits.

The successful acquisition of producing properties requires an assessment of numerous factors

beyond our control, including, without limitation:

• recoverable reserves;
• exploration potential;
• future oil and natural gas prices;
• operating costs; and
• potential environmental and other liabilities.

In connection with such an assessment, we perform a review of the subject properties that we believe
to be generally consistent with industry practices. The resulting assessments are inexact and their
accuracy uncertain, and such a review may not reveal all existing or potential problems, nor will it
necessarily permit us to become sufficiently familiar with the properties to fully assess their merits and
deficiencies. Inspections may not always be performed on every well, and structural and environmental
problems are not necessarily observable even when an inspection is made.

Additionally, significant acquisitions can change the nature of our operations and business
depending upon the character of the acquired properties, which may be substantially different in operating
and geologic characteristics or geographic location than our existing properties. While our current
operations are focused in the East Texas/North Louisiana, South Texas and West Texas regions, we may
pursue acquisitions or properties located in other geographic areas.

We operate in a highly competitive industry, and our failure to remain competitive with our
competitors, many of which have greater resources than we do, could adversely affect our results of
operations.

The oil and natural gas industry is highly competitive in the search for and development and
acquisition of reserves. Our competitors often include companies that have greater financial and
personnel resources than we do. These resources could allow those competitors to price their products and
services more aggressively than we can, which could hurt our profitability. Moreover, our ability to
acquire additional properties and to discover reserves in the future will be dependent upon our ability to
evaluate and select suitable properties and to close transactions in a highly competitive environment.

Our competitors may use superior technology that we may be unable to afford or which would
require costly investment by us in order to compete.

If our competitors use or develop new technologies, we may be placed at a competitive
disadvantage, and competitive pressures may force us to implement new technologies at a substantial
cost. In addition, our competitors may have greater financial, technical and personnel resources that allow

36

them to enjoy technological advances and may in the future allow them to implement new technologies
before we can. We cannot be certain that we will be able to implement technologies on a timely basis or
at a cost that is acceptable to us. One or more of the technologies that we currently use or that we may
implement in the future may become obsolete. All of these factors may inhibit our ability to acquire
additional prospects and compete successfully in the future.

Substantial exploration and development activities could require significant outside capital, which
could dilute the value of our common shares and restrict our activities. Also, we may not be able to
obtain needed capital or financing on satisfactory terms, which could lead to a limitation of our
future business opportunities and a decline in our oil and natural gas reserves.

We expect to expend substantial capital in the acquisition of, exploration for and development of oil
and natural gas reserves. In order to finance these activities, we may need to alter or increase our
capitalization substantially through the issuance of debt or equity securities, the sale of non-strategic
assets or other means. The issuance of additional equity securities could have a dilutive effect on the
value of our common shares, and may not be possible on terms acceptable to us given the current
volatility in the financial markets. The issuance of additional debt would require that a portion of our cash
flow from operations be used for the payment of interest on our debt, thereby reducing our ability to use
our cash flow to fund working capital, capital expenditures, acquisitions, dividends and general corporate
requirements, which could place us at a competitive disadvantage relative to other competitors.
Additionally, if our revenues decrease as a result of lower oil or natural gas prices, operating difficulties
or declines in reserves, our ability to obtain the capital necessary to undertake or complete future
exploration and development programs and to pursue other opportunities may be limited, which could
result in a curtailment of our operations relating to exploration and development of our prospects, which
in turn could result in a decline in our oil and natural gas reserves.

If oil prices decline and natural gas prices remain low or continue to decline, we may be required to
write-down the carrying values and/or the estimates of total reserves of our oil and natural gas
properties, which would constitute a non-cash charge to earnings and adversely affect our results of
operations.

Accounting rules applicable to us require that we review periodically the carrying value of our oil
and natural gas properties for possible impairment. Based on specific market factors and circumstances at
the time of prospective impairment reviews and the continuing evaluation of development plans,
production data, economics and other factors, we may be required to write down the carrying value of our
oil and natural gas properties. A write-down constitutes a non-cash charge to earnings. We may incur
non-cash charges in the future, which could have a material adverse effect on our results of operations in
the period taken. We may also reduce our estimates of the reserves that may be economically recovered,
which could have the effect of reducing the total value of our reserves. Such a reduction in carrying value
could impact our borrowing ability and may result
in accelerating the repayment date of any
outstanding debt.

Our reserve estimates depend on many assumptions that may turn out to be inaccurate. Any material
inaccuracies in our reserve estimates or underlying assumptions will materially affect the quantities
and present value of our reserves.

Reserve engineering is a subjective process of estimating the recovery from underground
accumulations of oil and natural gas that cannot be precisely measured. The accuracy of any reserve

37

estimate depends on the quality of available data, production history and engineering and geological
interpretation and judgment. Because all reserve estimates are to some degree imprecise, the quantities of oil
and natural gas that are ultimately recovered, production and operating costs, the amount and timing of
future development expenditures and future oil and natural gas prices may all differ materially from those
assumed in these estimates. The information regarding present value of the future net cash flows attributable
to our proved oil and natural gas reserves is only estimated and should not be construed as the current
market value of the oil and natural gas reserves attributable to our properties. Thus, such information
includes revisions of certain reserve estimates attributable to proved properties included in the preceding
year’s estimates. Such revisions reflect additional information from subsequent activities, production history
of the properties involved and any adjustments in the projected economic life of such properties resulting
from changes in product prices. Any future downward revisions could adversely affect our financial
condition, our borrowing ability, our future prospects and the value of our common stock.

As of December 31, 2012, 38% of our total proved reserves were undeveloped and 8% were
developed non-producing. These reserves may not ultimately be developed or produced. Furthermore, not
all of our undeveloped or developed non-producing reserves may be ultimately produced at the time
periods we have planned, at the costs we have budgeted, or at all. As a result, we may not find
commercially viable quantities of oil and natural gas, which in turn may result in a material adverse effect
on our results of operations.

If we are unsuccessful at marketing our oil and natural gas at commercially acceptable prices, our
profitability will decline.

Our ability to market oil and natural gas at commercially acceptable prices depends on, among other

factors, the following:

• the availability and capacity of gathering systems and pipelines;
• federal and state regulation of production and transportation;
• changes in supply and demand; and
• general economic conditions.

Our inability to respond appropriately to changes in these factors could negatively affect our

profitability.

Market conditions or operational impediments may hinder our access to oil and natural gas markets
or delay our production.

Market conditions or

the unavailability of satisfactory oil and natural gas transportation
arrangements may hinder our access to oil and natural gas markets or delay our production. The
availability of a ready market for our oil and natural gas production depends on a number of factors,
including the demand for and supply of oil and natural gas and the proximity of reserves to pipelines and
processing facilities. Our ability to market our production depends in a substantial part on the availability
and capacity of gathering systems, pipelines and processing facilities, in some cases owned and operated
by third parties. Our failure to obtain such services on acceptable terms could materially harm our
business. We may be required to shut in wells for a lack of a market or because of the inadequacy or
unavailability of pipelines or gathering system capacity. If that were to occur, then we would be unable to
realize revenue from those wells until arrangements were made to deliver our production to market.

38

We depend on our key personnel and the loss of any of these individuals could have a material
adverse effect on our operations.

We believe that the success of our business strategy and our ability to operate profitably depend on
the continued employment of M. Jay Allison, our President and Chief Executive Officer, and a limited
number of other senior management personnel. Loss of the services of Mr. Allison or any of those other
individuals could have a material adverse effect on our operations.

Our insurance coverage may not be sufficient or may not be available to cover some liabilities or
losses that we may incur.

If we suffer a significant accident or other loss, our insurance coverage will be net of our deductibles
and may not be sufficient to pay the full current market value or current replacement value of our lost
investment, which could result in a material adverse impact on our operations and financial condition.
Our insurance does not protect us against all operational risks. We do not carry business interruption
insurance. For some risks, we may not obtain insurance if we believe the cost of available insurance is
excessive relative to the risks presented. Because third party drilling contractors are used to drill our
wells, we may not realize the full benefit of workers’ compensation laws in dealing with their employees.
In addition, some risks, including pollution and environmental risks, generally are not fully insurable.

We are subject to extensive governmental laws and regulations that may adversely affect the cost,
manner or feasibility of doing business.

Our operations and facilities are subject to extensive federal, state and local laws and regulations
relating to the exploration for, and the development, production and transportation of, oil and natural gas,
and operating safety. Future laws or regulations, any adverse changes in the interpretation of existing laws
and regulations or our failure to comply with existing legal requirements may harm our business, results
of operations and financial condition. We may be required to make large and unanticipated capital
expenditures to comply with governmental laws and regulations, such as:

• lease permit restrictions;
• drilling bonds and other financial responsibility requirements, such as plug and abandonment

bonds;

• spacing of wells;
• unitization and pooling of properties;
• safety precautions;
• regulatory requirements; and
• taxation.

Under these laws and regulations, we could be liable for:

• personal injuries;
• property and natural resource damages;
• well reclamation costs; and
• governmental sanctions, such as fines and penalties.

Our operations could be significantly delayed or curtailed and our cost of operations could
significantly increase as a result of regulatory requirements or restrictions. We are unable to predict the
ultimate cost of compliance with these requirements or their effect on our operations.

39

Our operations may incur substantial liabilities to comply with environmental laws and regulations.

Our oil and natural gas operations are subject

laws and
regulations relating to the release or disposal of materials into the environment and otherwise relating to
environmental protection. These laws and regulations:

to stringent federal, state and local

• require the acquisition of one or more permits before drilling commences;
• impose limitations on where drilling can occur and/or requires mitigation before authorizing

drilling in certain locations;

• restrict

the types, quantities and concentration of substances that can be released into the

environment in connection with drilling and production activities;

• require reporting of significant releases, and annual reporting of the nature and quantity of

emissions, discharges and other releases into the environment;

• limit or prohibit drilling activities on certain lands lying within wilderness, wetlands and other

protected areas; and

• impose substantial liabilities for pollution resulting from our operations.

Failure to comply with these laws and regulations may result in:

• the assessment of administrative, civil and criminal penalties;
• the incurrence of investigatory or remedial obligations; and
• the imposition of injunctive relief.

In June 2009 the United States House of Representatives passed the American Clean Energy and
Security Act of 2009. A similar bill, the Clean Energy Jobs and American Power Act, introduced in the
Senate, did not pass. Both bills contained the basic feature of establishing a “cap and trade” system for
restricting greenhouse gas emissions in the United States. Under such a system, certain sources of
greenhouse gas emissions would be required to obtain greenhouse gas emission “allowances”
corresponding to their annual emissions of greenhouse gases. The number of emission allowances issued
each year would decline as necessary over time to meet overall emission reduction goals. As the number
of greenhouse gas emission allowances declines each year, the cost or value of allowances is expected to
escalate significantly. It appears that the prospects for a cap and trade system such as that proposed in
these bills have dimmed significantly; however, the EPA has moved ahead with its efforts to regulate
GHG emissions from certain sources by rule. The EPA issued Subpart W of the Final Mandatory
Reporting of Greenhouse Gases Rule, which required petroleum and natural gas systems that emit 25,000
metric tons of CO2e or more per year to begin collecting GHG emissions data under a new reporting
system. We believe we have met all of the reporting requirements under these new regulations. Beyond
measuring and reporting, the EPA issued an “Endangerment Finding” under section 202(a) of the Clean
Air Act, concluding greenhouse gas pollution threatens the public health and welfare of current and future
generations. The EPA has adopted regulations that would require permits for and reductions in
greenhouse gas emissions for certain facilities. Since all of our oil and natural gas production is in the
United States, these laws or regulations that have been or may be adopted to restrict or reduce emissions
of greenhouse gases could require us to incur substantial increased operating costs, and could have an
adverse effect on demand for the oil and natural gas we produce.

In June 2010 the Bureau of Land Management issued a proposed oil and gas leasing reform. The
proposal would require, among other things, a more detailed environmental review prior to leasing oil and
natural gas resources on federal lands, increased public engagement in the development of Master
Leasing Plans prior to leasing areas where intensive new oil and gas development is anticipated, and a
comprehensive parcel review process with greater public involvement in the identification of key
environmental resource values before a parcel
is leased. New leases would incorporate adaptive
management stipulations, requiring lessees to monitor and respond to observed environmental impacts,

40

possibly through the implementation of expensive new control measures or curtailment of operations,
potentially reducing profitability. The proposed policy could have the effect of reducing the amount of
new federal lands made available for lease, increasing the competition for and cost of available parcels.

Changes in environmental laws and regulations occur frequently, and any changes that result in more
stringent or costly restrictions on emissions, and/or waste handling, storage, transport, disposal or cleanup
requirements could require us to make significant expenditures to reach and maintain compliance and
may otherwise have a material adverse effect on our industry in general and on our own results of
operations, competitive position or financial condition. Under these environmental laws and regulations,
we could be held strictly liable for the removal or remediation of previously released materials or
property contamination regardless of whether we were responsible for the release or contamination or if
our operations met previous standards in the industry at
the time they were performed. Future
environmental laws and regulations, including proposed legislation regulating climate change, may
negatively impact our industry. The costs of compliance with these requirements may have an adverse
impact on our financial condition, results of operations and cash flows.

Provisions of our articles of incorporation, bylaws and Nevada law will make it more difficult to
effect a change in control of us, which could adversely affect the price of our common stock.

Nevada corporate law and our articles of incorporation and bylaws contain provisions that could

delay, defer or prevent a change in control of us. These provisions include:

• allowing for authorized but unissued shares of common and preferred stock;
• a classified board of directors;
• requiring special stockholder meetings to be called only by our chairman of the board, our chief
executive officer, a majority of the board or the holders of at least 10% of our outstanding stock
entitled to vote at a special meeting;

• requiring removal of directors by a supermajority stockholder vote;
• prohibiting cumulative voting in the election of directors; and
• Nevada control share laws that may limit voting rights in shares representing a controlling interest

in us.

These provisions could make an acquisition of us by means of a tender offer or proxy contest or
removal of our incumbent directors more difficult. As a result, these provisions could make it more
difficult for a third party to acquire us, even if doing so would benefit our stockholders, which may limit
the price that investors are willing to pay in the future for shares of our common stock.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with our selected historical
consolidated financial data and our accompanying consolidated financial statements and the notes to
those financial statements included elsewhere in this report. The following discussion includes forward-
looking statements that reflect our plans, estimates and beliefs. Our actual results could differ materially
from those discussed in these forward-looking statements. Factors that could cause or contribute to such
differences include, but are not limited to, those discussed below and elsewhere in this report, particularly
in “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements.”

Overview

We are an independent energy company engaged in the acquisition, exploration, development and
production of oil and natural gas in the United States. We own interests in 1,643 producing oil and natural
gas wells (914.5 net to us) and we operate 962 of these wells. In managing our business, we are
concerned primarily with maximizing return on our stockholders’ equity. To accomplish this goal, we
focus on profitably increasing our oil and natural gas reserves and production.

Our future growth will be driven primarily by acquisition, development and exploration activities. In
2012 our growth in production and proved reserves was primarily driven by our successful oil focused
drilling activities. Under our current drilling budget, we plan to spend approximately $420.0 million in
2013 for development and exploration activities, which will primarily be focused on oil projects. We plan
to drill 85 wells (58.1 net to us) in 2013, of which 75 wells (54.5 net to us) will target oil in our South
Texas and West Texas regions and ten will target natural gas in our East Texas / North Louisiana region.
However, we could increase or decrease the number of wells that we drill depending on oil and natural
gas prices. We do not specifically budget for acquisitions as the timing and size of acquisitions are not
predictable.

44

We use the successful efforts method of accounting, which allows only for the capitalization of costs
associated with developing proven oil and natural gas properties as well as exploration costs associated
with successful exploration activities. Accordingly, our exploration costs consist of costs we incur to
acquire and reprocess 3-D seismic data, impairments of our unevaluated leasehold where we were not
successful in discovering reserves and the costs of unsuccessful exploratory wells that we drill.

We generally sell our oil and natural gas at current market prices at the point our wells connect to
third party purchaser pipelines. We have entered into certain transportation and treating agreements with
midstream and pipeline companies to transport a substantial portion of our natural gas production in
North Louisiana to long-haul gas pipelines. We market our products several different ways depending
upon a number of factors, including the availability of purchasers for the product, the availability and cost
of pipelines near our wells, market prices, pipeline constraints and operational flexibility. Accordingly,
our revenues are heavily dependent upon the prices of, and demand for, oil and natural gas. Oil and
natural gas prices have historically been volatile and are likely to remain volatile in the future.

Our operating costs are generally comprised of several components,

including costs of field
insurance, repair and maintenance costs, production supplies, fuel used in operations,

personnel,
transportation costs, workover expenses and state production and ad valorem taxes.

Like all oil and natural gas exploration and production companies, we face the constant challenge of
replacing our reserves. Although in the past we have offset the effect of declining production rates from
existing properties through successful acquisition and drilling efforts, there can be no assurance that we
will be able to continue to offset production declines or maintain production at current rates through
future acquisitions or drilling activity. Our future growth will depend on our ability to continue to add
new reserves in excess of production.

Our operations and facilities are subject to extensive federal, state and local laws and regulations
relating to the exploration for, and the development, production and transportation of, oil and natural gas,
and operating safety. Future laws or regulations, any adverse changes in the interpretation of existing laws
and regulations or our failure to comply with existing legal requirements may have an adverse effect on
our business, results of operations and financial condition. Applicable environmental regulations require
us to remove our equipment after production has ceased, to plug and abandon our wells and to remediate
any environmental damage our operations may have caused. The present value of the estimated future
costs to plug and abandon our oil and gas wells and to dismantle and remove our production facilities is
included in our reserve for future abandonment costs, which was $18.0 million as of December 31, 2012.

Oil and gas sales. Our oil and gas sales decreased $2.5 million (1%) in 2012 to $431.9 million
from sales of $434.4 million in 2011. Our oil production in 2012 increased by 175% while our natural gas
production decreased by 9% from our 2011 production levels. On an equivalent unit basis, our production
in 2012 increased by 1% over 2011. Our successful drilling program grew our oil production which offset
the decline in natural gas production. Prices realized for oil sales increased by 1% in 2012 as compared to
2011 while the average price we realized for natural gas sales decreased by 36% in 2012 as compared to
2011. Our oil hedging program generated $9.8 million in realized gains in 2012. Including the results of
our hedging program, our average oil price in 2012 of $101.18 increased 6% above last year’s average
price.

Production taxes. Production taxes increased $10.3 million or 282% to $14.0 million in 2012 from
$3.7 million in 2011. The increase in 2012 is due to the significant growth in our oil sales during the year.
Much of our natural gas sales in 2011 and 2012 qualify for exemption from state production taxes.

Gathering and transportation. Gathering and transportation costs in 2012 decreased $1.2 million
(4%) to $27.3 million as compared to $28.5 million in 2011 due to the lower natural gas volumes that we
produced in North Louisiana in 2012.

lease operating expenses,

Lease operating expenses. Our

including ad valorem taxes, of
$60.6 million in 2012 were $14.0 million or 30% higher than our operating expenses of $46.6 million in
2011. Our lease operating expense per Mcfe produced increased by 29% to $1.06 per Mcfe in 2012 as
compared to $0.82 per Mcfe in 2011. The increase mainly reflects our growing oil production. Our oil
wells are typically more costly to operate than our natural gas wells. Oil production comprised 14% of
our total production in 2012 as compared to 5% in 2011.

Exploration expense. We incurred $61.4 million in exploration expense in 2012 as compared to
$10.1 million in 2011. Exploration expense in 2012 consisted of $61.3 million of impairments of

46

unevaluated leasehold costs and $0.1 million for the acquisition of seismic data. Our 2011 exploration
cost consisted of $9.8 million of impairments of unevaluated leasehold costs and $0.3 million for the
acquisition of seismic data.

Depreciation, depletion and amortization expense (“DD&A”). DD&A of $365.3 million was an
increase of $74.5 million (26%) over DD&A of $290.8 million in 2011. Our DD&A rate per Mcfe
produced averaged $3.83 in 2012 as compared to $3.00 for 2011. The increase in DD&A primarily
resulted from increased development costs per Mcfe associated with the oil wells drilled in 2012, and the
substantial decline in our proved natural gas reserves due to the low natural gas prices in 2012.

Impairment of oil and gas properties. We recorded impairments to our oil and gas properties of
$25.4 million and $60.8 million in 2012 and 2011, respectively. These impairments relate to fields where
an impairment was indicated based on estimated future cash flows from the properties.

General and administrative expenses. General and administrative expense of $33.8 million for 2012
was 4% lower than general and administrative expense of $35.2 million for 2011. The decrease primarily
reflects lower stock based compensation in 2012. Stock based compensation decreased by $1.3 million to
$13.7 million in 2012 as compared to $15.0 million in 2011.

Interest expense.

Interest expense increased $21.9 million (51%) to $64.6 million in 2012 from
interest expense of $42.7 million in 2011. The increase was primarily related to the increase in
outstanding debt during 2012 including the issuance of $300.0 million in senior notes in June 2012.
Average borrowings under our bank credit facility increased to $482.7 million in 2012 as compared to
$121.4 million for 2011. The average interest rate on the outstanding borrowings under our credit facility
of 3.0% in 2012 was higher than the interest rate of 2.2% in 2011. We capitalized interest of $20.9 million
and $13.2 million in 2012 and 2011, respectively, which amounts reduced interest expense.

Income taxes. The benefit

from income taxes increased in 2012 to $47.4 million from
$14.6 million in 2011 due to the higher net loss in 2012. Our effective tax rate of 32% in 2012 and 30% in
2011 differed from the federal income tax rate of 35% primarily due to the effect of nondeductible
compensation and state income taxes.

Net loss. We reported a loss of $100.1 million for 2012 as compared to a loss of $33.5 million for
2011. The loss per share for 2012 was $2.16 on weighted average shares outstanding of 46.4 million as
compared to a loss per share of $0.73 for 2011 on weighted average shares outstanding of 46.0 million.
The loss in 2012 was primarily related to the increase in DD&A expense and impairments of proved and
unproved properties of $86.7 million ($56.3 million after income taxes) which were offset in part by gains
on sales of properties of $24.3 million ($15.8 million after income taxes) and sales of marketable
securities of $26.6 million ($17.3 million after income taxes) and also unrealized gains on our oil
derivatives of $11.5 million ($7.5 million after tax). The loss in 2011 was primarily related to the
impairments to proved and unproved properties in 2011 of $70.6 million ($45.9 million after income
taxes) offset in part by gains on sales of marketable securities of $35.1 million ($22.8 million after
income taxes).

higher prices realized for oil sales in 2011. Our production in 2011 increased by 31% over 2010’s
production as production from new wells drilled in South Texas targeting the Eagle Ford shale and in
North Louisiana targeting the Haynesville/Bossier shales exceeded declines from our existing producing
properties. Prices realized for oil sales increased by 40% in 2011 as compared to 2010 while the average
price we realized for natural gas sales decreased by 10% in 2011 as compared to 2010. During 2011 we
drilled 87 wells (47.7 net to us), 62 of which were Haynesville or Bossier shale horizontal wells and 20 of
which were Eagle Ford shale horizontal wells. At December 31, 2011 we had 23 wells (15.5 net to us)
that were drilled in 2011 awaiting completion.

Production taxes. Production taxes decreased $6.2 million (63%) to $3.7 million in 2011 from
$9.9 million in 2010. Our Haynesville and Bossier shale wells, which comprise a large percentage of our
production, qualify for exemption from certain state production taxes. The exempt wells together with the
lower natural gas prices account for the decrease.

Gathering and transportation. Gathering and transportation costs in 2011 increased $11.2 million
(65%) to $28.5 million as compared to $17.3 million in 2010 due to the transportation costs related to the
higher production from our Haynesville/Bossier shale properties in North Louisiana.

Lease operating expenses. Our

including ad valorem taxes, of
$46.6 million in 2011 were $6.9 million or 13% lower than our operating expenses of $53.5 million in
2010. Our lease operating expense per Mcfe produced decreased by 33% to $0.48 per Mcfe in 2011 as
compared to $0.72 per Mcfe in 2010. The decreases in lease operating expenses are primarily due to the
sale of our higher operating cost properties in Mississippi in 2010.

lease operating expenses,

Exploration expense. We incurred $10.1 million in exploration expense in 2011 as compared to
$2.6 million in 2010. Exploration expense in 2011 consisted of $9.8 million of impairments of
unevaluated leasehold costs and $0.3 million for the acquisition of seismic data. Our 2010 exploration
cost primarily related to costs incurred for the acquisition of seismic data.

48

DD&A. DD&A of $290.8 million increased $77.0 million (36%) as compared to DD&A of
$213.8 million in 2010. Our DD&A rate per Mcfe produced averaged $3.00 in 2011 as compared to
$2.91 for 2010. The increase in DD&A primarily resulted from our 31% growth in production in 2011.

Impairment of oil and gas properties. We recorded impairments to our oil and gas properties of
$60.8 million and $0.2 million in 2011 and 2010, respectively. These impairments relate to fields where
an impairment was indicated based on estimated future cash flows from the properties. The 2011
impairment is a result of lower anticipated natural gas prices.

General and administrative expenses. General and administrative expense of $35.2 million for
2011 was 5% lower than general and administrative expense of $37.2 million for 2010. The decrease
primarily reflects our lower personnel costs in 2011. Stock based compensation decreased by $2.4 million
to $15.0 million in 2011 as compared to $17.4 million in 2010.

Interest expense.

Interest expense increased $13.2 million (45%) to $42.7 million in 2011 from
interest expense of $29.5 million in 2010. The increase was primarily related to the increase in
outstanding debt during 2011 including the issuance of $300.0 million in senior notes in March 2011.
Average borrowings under our bank credit facility increased to $121.4 million in 2011 as compared to
$70.0 million for 2010. The average interest rate on the outstanding borrowings under our credit facility
of 2.2% in 2011 was unchanged from 2010. We capitalized interest of $13.2 million and $13.0 million in
2011 and 2010, respectively, which reduced interest expense. Interest expense in 2011 includes
$1.1 million for the early retirement of our 6 7⁄8% senior notes which were due in March 2012.

Income taxes. The benefit from income taxes increased in 2011 to $14.6 million from $4.8 million
in 2010 due to the higher net loss in 2011. Our effective tax rate of 30% in 2011 and 20% in 2010 differed
from the federal income tax rate of 35% primarily due to the effect of nondeductible compensation and
state income taxes.

Net loss. We reported a loss of $33.5 million for 2011 as compared to a loss of $19.6 million for
2010. The loss per share for 2011 was $0.73 on weighted average shares outstanding of 46.0 million as
compared to a loss per share of $0.43 for 2010 on weighted average shares outstanding of 45.6 million.
The loss in 2011 was primarily related to the impairments to proved and unproved properties in 2011 of
$70.6 million ($45.9 million after income taxes) offset in part by gains on sales of marketable securities
of $35.1 million ($22.8 million after income taxes). The loss in 2010 was primarily related to the loss on
our divestiture of oil and gas properties in Mississippi of $25.8 million ($16.8 million after income taxes).

Liquidity and Capital Resources

Funding for our activities has historically been provided by our operating cash flow, debt or equity
financings and asset dispositions. Our net cash provided by operating activities in 2012 totaled
$262.2 million. Our other primary sources of funds in 2012 included $285.9 million of net proceeds from
a senior notes offering and $204.4 million from sales of assets. In 2011, our net cash flow provided by
operating activities totaled $284.9 million, while our other primary sources of funds included $293.4
million of net proceeds from a senior notes offering, $555.0 million of borrowings under our bank credit
facility and $53.4 million of proceeds from sales of marketable securities. In 2010, our net cash flow
provided by operating activities from continuing operations totaled $311.7 million. Our other primary
source of funds in 2010 was $96.9 million of net proceeds from sales of oil and gas properties and
marketable securities and $45.0 million of borrowings under our bank credit facility.

Our cash flow from operating activities in 2012 of $262.2 million represented a decrease of
$22.7 million from our cash from operating activities of $284.9 million in 2011. Cash flow from

49

operations excluding changes in working capital accounts of $261.3 million in 2012 decreased by $36.3
million or 12% as compared to $297.6 million in 2011 due to the lower revenues we received because of
the decline in natural gas prices during 2012 which was partially offset by higher oil production. Our cash
flow from operating activities in 2011 decreased by $26.8 million to $284.9 million as compared to
$311.7 million in 2010 primarily due to changes in working capital at the end of 2011.

Our primary need for capital, in addition to funding our ongoing operations, relates to the acquisition,
development and exploration of our oil and gas properties and the repayment of our debt. During 2012 our
capital expenditures of $550.6 million decreased by $497.1 million as compared to 2011 capital
expenditures of $1.0 billion due primarily to the acquisitions of proved and unproved properties we made in
2011. Capital expenditures in 2012 include $70.9 million spent to complete wells drilled in 2011. In 2011,
our capital expenditures of $1.0 billion increased by $502.0 million as compared to 2010 capital
expenditures of $545.7 million, mainly due to the acquisition of oil and gas properties in 2011.

Our annual capital expenditure activity is summarized in the following table:

The timing of most of our capital expenditures is discretionary because we have no material long-
for contracted drilling and completion services.
term capital expenditure commitments except
Consequently, we have a significant degree of flexibility to adjust the level of our capital expenditures as
circumstances warrant. We currently expect to spend approximately $445.0 million for development and
exploration projects and lease acquisitions in 2013, which will be funded primarily by cash flows from
operating activities, proceeds from asset sales and borrowings under our credit facility. Our operating
cash flow and, therefore, our capital expenditures are highly dependent on oil and natural gas prices and,
in particular, natural gas prices.

We do not have a specific acquisition budget for 2013 because the timing and size of acquisitions are
unpredictable. Smaller acquisitions will generally be funded from operating cash flow. With respect to
significant acquisitions, we intend to use borrowings under our bank credit facility, or other debt or equity
financings to the extent available, to finance such acquisitions. The availability and attractiveness of these
sources of financing will depend upon a number of factors, some of which will relate to our financial
condition and performance and some of which will be beyond our control, such as prevailing interest
rates, oil and natural gas prices and other market conditions. Lack of access to the debt or equity markets
due to general economic conditions could impede our ability to complete acquisitions.

We have a $850.0 million bank credit facility with Bank of Montreal, as the administrative agent.
The bank credit facility is a five-year revolving credit commitment that matures on November 30, 2015.

50

Indebtedness under the bank credit facility is secured by all of our and our wholly owned subsidiaries’
assets and is guaranteed by all of our wholly owned subsidiaries. The bank credit facility is subject to
borrowing base availability, which is redetermined semiannually based on the banks’ estimates of the
future net cash flows of our oil and natural gas properties. As of December 31, 2012, the borrowing base
was $570.0 million, $130.0 million of which was available. The borrowing base may be affected by the
performance of our properties and changes in oil and natural gas prices. The determination of the
borrowing base is at the sole discretion of the administrative agent and the bank group. Borrowings under
the bank credit facility bear interest, based on the utilization of the borrowing base, at our option at either
(1) LIBOR plus 1.75% to 2.75% or (2) the base rate (which is the higher of the administrative agent’s
prime rate, the federal funds rate plus 0.5% or 30 day LIBOR plus 1.0%) plus 0.75% to 1.75%. A
commitment fee of 0.5% is payable on the unused borrowing base. The bank credit facility contains
covenants that, among other things, restrict the payment of cash dividends in excess of $50.0 million,
limit the amount of consolidated debt that we may incur and limit our ability to make certain loans and
investments. The only financial covenants are the maintenance of a ratio of current assets, including the
availability under the bank credit facility, to current liabilities and maintenance of a leverage ratio. We
were in compliance with these covenants as of December 31, 2012.

We have $300.0 million of 8 3⁄8% senior notes outstanding which are due October 15, 2017,
$300.0 million of 7 3⁄4% senior notes outstanding which are due April 1, 2019 and $300.0 million of 9 1⁄2%
senior notes outstanding which are due June 15, 2020. All senior notes have semi-annual interest payment
obligations, are unsecured obligations and are guaranteed by all of our material subsidiaries.

On January 1, 2011, we had $172.0 million in principal amount of 6 7⁄8% senior notes outstanding
due in 2012 (the “2012 Notes”). We redeemed all of the 2012 Notes in 2011 for $172.4 million. The early
extinguishment of the 2012 Notes resulted in a loss of $1.1 million. This loss is comprised of the
premium paid for the redemption of the 2012 Notes, the costs incurred related to the tender offer, and the
write-off of unamortized debt issuance costs related to the 2012 Notes.

We believe that our cash flow from operations and available borrowings under our bank credit
facility will be sufficient to fund our operations and future growth as contemplated under our current
business plan. However, if our plans or assumptions change or if our assumptions prove to be inaccurate,
we may be required to seek additional capital. We cannot provide any assurance that we will be able to
obtain such capital, or if such capital is available, that we will be able to obtain it on acceptable terms.

We have obligations to incur future payments for dismantlement, abandonment and restoration costs
of oil and gas properties. These payments are currently estimated to be incurred primarily after 2017. We
record a separate liability for the fair value of these asset retirement obligations, which totaled
$18.0 million as of December 31, 2012.

Federal Taxation

At December 31, 2012 we had U.S. federal net operating loss carryforwards of approximately
$192.3 million and Louisiana state net operating loss carryforwards of approximately $536.4 million.
Utilization of $36.9 million of our U.S. federal net operating loss carryforwards is limited to
approximately $1.1 million per year pursuant to a prior change of control of an acquired company and a
valuation allowance of $23.0 million has been established for the estimated U.S. federal net operating loss
carryforwards that will not be utilized. Realization of the remaining U.S. federal net operating loss
carryforwards requires Comstock to generate taxable income within the carryforward period. A valuation
allowance of $288.0 million has been established against our Louisiana state net operating loss
carryforwards due to the uncertainty of generating taxable income in the state of Louisiana prior to the
expiration of the carryforward period.

Our federal income tax returns for the years subsequent to December 31, 2007 remain subject to
examination. Our income tax returns in major state income tax jurisdictions remain subject to examination
for various periods subsequent to December 31, 2007. We currently believe that our significant filing
positions are highly certain and that all of our significant income tax filing positions and deductions would
be sustained upon audit or the final resolution would not have a material effect on our consolidated financial
statements. Therefore, we have not established any significant reserves for uncertain tax positions. Interest
and penalties resulting from audits by tax authorities have been immaterial and are included in the provision
for income taxes in the consolidated statements of operations.

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted
in the United States requires us to make estimates and use assumptions that can affect the reported
amounts of assets, liabilities, revenues or expenses.

Successful efforts accounting. We are required to select among alternative acceptable accounting
policies. There are two generally acceptable methods for accounting for oil and gas producing activities.
The full cost method allows the capitalization of all costs associated with finding oil and natural gas
reserves, including certain general and administrative expenses. The successful efforts method allows
only for the capitalization of costs associated with developing proven oil and natural gas properties as
well as exploration costs associated with successful exploration projects. Costs related to exploration that
are not successful are expensed when it is determined that commercially productive oil and gas reserves
were not found. We have elected to use the successful efforts method to account for our oil and gas
activities and we do not capitalize any of our general and administrative expenses.

Oil and natural gas reserve quantities. The determination of depreciation, depletion and
amortization expense is highly dependent on the estimates of the proved oil and natural gas reserves
attributable to our properties. The determination of whether impairments should be recognized on our oil
and gas properties is also dependent on these estimates, as well as estimates of probable reserves. Reserve
engineering is a subjective process of estimating underground accumulations of oil and natural gas that
cannot be precisely measured. The accuracy of any reserve estimate depends on the quality of available
data, production history and engineering and geological interpretation and judgment. Because all reserve

52

estimates are to some degree imprecise, the quantities of oil and natural gas that are ultimately recovered,
production and operating costs, the amount and timing of future development expenditures and future oil
and natural gas prices may all differ materially from those assumed in these estimates. The information
regarding present value of the future net cash flows attributable to our proved oil and natural gas reserves
are estimates only and should not be construed as the current market value of the estimated oil and natural
gas reserves attributable to our properties. Thus, such information includes revisions of certain reserve
estimates attributable to proved properties included in the preceding year’s estimates. Such revisions
reflect additional information from subsequent activities, production history of the properties involved
and any adjustments in the projected economic life of such properties resulting from changes in product
prices. Any future downward revisions could adversely affect our financial condition, our borrowing
ability, our future prospects and the value of our common stock.

Impairment of oil and gas properties. We evaluate our properties on a field area basis for potential
impairment when circumstances indicate that the carrying value of an asset may not be recoverable. If
impairment is indicated based on a comparison of the asset’s carrying value to its undiscounted expected
future net cash flows, then it is recognized to the extent that the carrying value exceeds fair value. A
significant amount of judgment is involved in performing these evaluations since the results are based on
estimated future events. Expected future cash flows are determined using estimated future prices based on
market based forward prices applied to projected future production volumes. The projected production
volumes are based on the property’s proved and risk adjusted probable oil and natural gas reserve
estimates at the end of the period. The estimated future cash flows that we use in our assessment of the
need for an impairment are based on market prices for oil and natural gas for the next three years, with a
5% escalation of prices for subsequent years. Prices are not escalated to levels that exceed observed
historical market prices. Costs are also assumed to escalate at a rate that is based on our historical
experience, currently estimated at 2% per annum. The oil and natural gas prices used for determining
asset impairments will generally differ from those used in the standardized measure of discounted future
net cash flows because the standardized measure requires the use of the average first day of the month
historical price for the year. To the extent that oil and natural gas prices do not increase as anticipated in
these assumptions or costs increase at a greater rate than assumed, certain of our evaluated properties
which presently have a carrying value of $463.0 million may require impairment in the future. The
amount of such impairments would be based on the write down of these properties to their then current
estimated fair value. In addition to these properties, other properties may become impaired due to
downward revisions in reserve or price estimates or for other reasons.

Asset retirement obligations. We have obligations to remove tangible equipment and facilities and
to restore land at the end of oil and gas production operations. Our removal and restoration obligations are
primarily associated with plugging and abandoning wells and removing and disposing of any surface
equipment used in production operations. Estimating the future restoration and removal costs is difficult
and requires management to make estimates and judgments because most of the removal obligations are
many years in the future. Asset removal technologies and costs are constantly changing, as are regulatory,
political, environmental, safety and public relations considerations.

Stock-based compensation. We follow the fair value based method in accounting for equity-based
compensation. Under the fair value based method, compensation cost is measured at the grant date based
on the fair value of the award and is recognized on a straight-line basis over the award vesting period.

Related Party Transactions

In recent years, we have not entered into any material transactions with our officers or directors apart
from the compensation they are provided for their services. We also have not entered into any business
transactions with our significant stockholders or any other related parties.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Oil and Natural Gas Prices

Our financial condition, results of operations and capital resources are highly dependent upon the
prevailing market prices of oil and natural gas. These commodity prices are subject to wide fluctuations
and market uncertainties due to a variety of factors that are beyond our control. Factors influencing oil
and natural gas prices include the level of global demand for oil, the foreign supply of oil and natural gas,
the establishment of and compliance with production quotas by oil exporting countries, weather
conditions which determine the demand for natural gas, the price and availability of alternative fuels and
overall economic conditions. It is impossible to predict future oil and natural gas prices with any degree
of certainty. Sustained weakness in oil and natural gas prices may adversely affect our financial condition
and results of operations, and may also reduce the amount of oil and natural gas reserves that we can
produce economically. Any reduction in our oil and natural gas reserves, including reductions due to price
fluctuations, can have an adverse affect on our ability to obtain capital for our exploration and
development activities. Similarly, any improvements in oil and natural gas prices can have a favorable
impact on our financial condition, results of operations and capital resources. Based on our oil and natural
gas production in 2012, a $1.00 change in the price per barrel of oil would have resulted in a change in
our cash flow for such period by approximately $0.6 million and a $0.10 change in the price per Mcf of
natural gas would have changed our cash flow by approximately $8.0 million.

We have entered into oil price swap agreements covering 2.2 million barrels of our expected 2013
oil production which fix the NYMEX West Texas Intermediate (“WTI”) price at $98.67 per barrel. As of
December 31, 2012, our outstanding oil swap agreements had a fair value of $11.7 million. The change in
the fair value of our oil swaps that would result from a 10% change in commodities prices at
December 31, 2012 would be $12.9 million. Such a change in fair value could be a gain or a loss
depending on whether prices increase or decrease.

Interest Rates

At December 31, 2012, we had $1.3 billion of long-term debt. Of this amount, $300.0 million bears
interest at 8 3⁄8%, $300.0 million bears interest at a fixed rate of 7 3⁄4%, and $300.0 million bears interest at
9 1⁄2%. The fair market value of our fixed rate debt as of December 31, 2012 was $942.0 million based on
the market price of approximately 107% of the face amount. At December 31, 2012, we had
$440.0 million outstanding under our bank credit facility, which is subject to variable rates of interest.
Borrowings under the bank credit facility bear interest at a fluctuating rate that is tied to LIBOR or the
corporate base rate, at our option. Any increase in these interest rates would have an adverse impact on
our results of operations and cash flow. Based on borrowings outstanding at December 31, 2012, a 100
basis point change in interest rates would change our annual interest expense on our variable rate debt by
approximately $4.4 million. We had no interest rate derivatives outstanding during 2012 or at
December 31, 2012.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Our consolidated financial statements are included on pages F-1 to F-34 of this report.

We have prepared these financial statements in conformity with generally accepted accounting
principles. We are responsible for the fairness and reliability of the financial statements and other
financial data included in this report. In the preparation of the financial statements, it is necessary for us
to make informed estimates and judgments based on currently available information on the effects of
certain events and transactions.

54

Our independent public accountants, Ernst & Young LLP, are engaged to audit our financial
statements and to express an opinion thereon. Their audit is conducted in accordance with auditing
standards generally accepted in the United States to enable them to report whether the financial
statements present fairly, in all material respects, our financial position and results of operations in
accordance with accounting principles generally accepted in the United States.

The audit committee of our board of directors is comprised of three directors who are not our
employees. This committee meets periodically with our independent public accountants and management.
Our independent public accountants have full and free access to the audit committee to meet, with and
without management being present, to discuss the results of their audits and the quality of our financial
reporting.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING

AND FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Controls and Procedures. Disclosure controls and procedures (as defined in
Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange
Act) are designed to provide reasonable assurance that information required to be disclosed in reports we
file or submit under the Exchange Act is recorded, processed, summarized and reported within the time
periods specified in the rules and forms of the SEC and that such information is accumulated and
communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as
appropriate to allow timely decisions regarding required disclosures.

We performed an evaluation of the effectiveness of our disclosure controls and procedures as of
December 31, 2012. The evaluation was performed with the participation of senior management of each
business segment and key corporate functions, and under the supervision of the Chief Executive Officer
and Chief Financial Officer. As described below, management has identified a material weakness in our
internal control over financial reporting, which is an integral component of our disclosure controls and
procedures. As a result of this material weakness, we concluded that our disclosure controls and
procedures were not effective as of December 31, 2012.

As part of the preparation of our financial statements for the year ended December 31, 2012, we
undertook a review of our accounting for oil price derivative financial instruments. We use derivative
financial instruments as a means of reducing our exposure to fluctuating commodity prices for oil and
natural gas. During the quarters ended March 31, 2012, June 30, 2012 and September 30, 2012, we
applied cash flow hedge accounting for our derivative financial instruments as provided for in Accounting
Standards Codification Topic 815, Derivatives and Hedging (“ASC 815”). Accordingly, we included
changes from period to period in the fair value of derivative financial instruments classified as cash flow
hedges as increases or decreases to Accumulated Other Comprehensive Income (“AOCI”). In order to
qualify for cash flow hedge accounting treatment, specific standards and contemporaneous documentation
requirements must be met. We believed that we had met those requirements and that our hedge
accounting treatment was permitted under ASC 815. However,
in connection with preparing our
2012 Annual Report, and based upon discussions with Ernst & Young, LLP, our independent public
accounting firm, we determined that our hedge documentation was not completed in a timely manner, and
as a result our commodity derivative financial instruments did not qualify for hedge accounting treatment
under ASC 815.

55

In February 2013 the Audit Committee of our Board of Directors concluded that our previously issued
consolidated financial statements contained a material error with respect to accounting for derivative
financial instruments, and should be restated. Accordingly, we are restating the consolidated financial
statements for each of the three months ended March 31, 2012, June 30, 2012 and September 30, 2012 to
reflect the change in the fair value of our derivative financial instruments, as a separate component of other
income (expenses) in our statements of operations rather than as a component of AOCI. We are also
reclassifying the realized gains and losses from our derivative financial instruments as a component of other
income (expenses) rather than as a component of oil and gas sales.

We have concluded, based on the circumstances involving the restatement of the financial statements
for the three months ended March 31, 2012, June 30, 2012 and September 30, 2012, that a material
weakness in internal control over financial reporting existed at December 31, 2012 with respect to the
design of our controls over the timeliness of documentation required to designate our derivative financial
instruments as cash flow hedges in accordance with ASC 815.

Management’s Report on Internal Control over Financial Reporting. We are responsible for
establishing and maintaining adequate internal control over financial reporting for the company. In order
to evaluate the effectiveness of internal control over financial reporting, as required by Section 404 of the
Sarbanes-Oxley Act, we conducted an assessment,
including testing, using the criteria in Internal
Control — Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway
Commission (COSO). Our system of internal control over financial reporting is designed to provide
reasonable assurance regarding the reliability of financial reporting and the preparation of financial
statements for external purposes in accordance with generally accepted accounting principles. 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.

A “material weakness” is a deficiency, or a combination of deficiencies, in internal control over
financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or
interim financial statements will not be prevented or detected on a timely basis. The material weakness
relating to the accounting for derivative financial
the
aforementioned accounts and disclosures that resulted in material misstatements in our interim financial
statements. Because of this material weakness, management has concluded that we did not maintain
effective internal control over financial reporting as of December 31, 2012. Our internal control over
financial reporting as of December 31, 2012, has been audited by Ernst & Young, LLP, an independent
registered public accounting firm, as stated in their report included herein.

instruments resulted in misstatements of

Plans for Remediation of the Material Weakness.

In response to the material weakness, we did
not account for derivative financial instruments as cash flow hedges under ASC 815 in the fourth quarter
of 2012 and are recognizing realized gains and losses and changes in the fair value of our derivative
financial instruments in current earnings as separate components of other income (losses). We are
developing a remediation plan to address the material weakness described above. The remediation plan
will include designing and implementing a control framework over entering into derivative financial
instruments to ensure that our accounting for derivative financial instruments which was affected by the
material control weakness is appropriate. The remediation plan will involve key leaders from across the
organization, including the Chief Executive Officer, the Chief Financial Officer and our internal auditors.
We will report quarterly and as needed to the Audit Committee of our Board of Directors on the progress
made toward completion of the remediation plan.

We continue to monitor the effectiveness of our internal control over financial reporting with respect
to our accounting for derivatives which was affected by the material weakness described above. We will

56

perform additional procedures prescribed by management, including the use of manual mitigating control
procedures, and we will employ any additional tools and resources deemed necessary to ensure that our
financial statements continue to be fairly stated in all material respects.

Changes in Internal Control over Financial Reporting. Except as noted above with respect to our
discontinuation of cash flow hedge accounting in the fourth quarter of 2012, there were no changes in our
internal control over financial reporting during the quarter ended December 31, 2012 that materially
affected or are reasonably likely to materially affect our internal control over financial reporting.
However, as described above under “Plans for Remediation of Material Weaknesses,” we have initiated a
process to improve the control environment and to remedy the control weakness described herein.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders
Comstock Resources, Inc.

We have audited Comstock Resources, Inc. and subsidiaries’ internal control over financial reporting as of
December 31, 2012, based on criteria established in Internal Control—Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission (the COSO criteria). Comstock Resources, Inc. and subsidiaries’
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

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.

limitations,

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting,
such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial
statements will not be prevented or detected on a timely basis. The following material weakness has been identified
and included in management’s assessment. Management has identified a material weakness in controls related to the
Company’s accounting for derivative financial instruments at December 31, 2012. We also have audited, in accordance
with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance
sheets of Comstock Resources, Inc. and subsidiaries as of December 31, 2011 and 2012, and the related consolidated
statements of operations, comprehensive loss, stockholders’ equity and cash flows for each of the three years in the
period ended December 31, 2012. This material weakness was considered in determining the nature, timing and extent
of audit tests applied in our audit of the 2012 financial statements and this report does not affect our report dated
February 28, 2013, which expressed an unqualified opinion on those financial statements.

In our opinion, because of the effect of the material weakness described above on the achievement of the
objectives of the control criteria, Comstock Resources, Inc. and subsidiaries have not maintained effective internal
control over financial reporting as of December 31, 2012, based on the COSO criteria.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders
Comstock Resources, Inc.

We have audited the accompanying consolidated balance sheets of Comstock Resources, Inc. and
subsidiaries as of December 31, 2011 and 2012, and the related consolidated statements of operations,
comprehensive loss, stockholders’ equity and cash flows for each of the three years in the period ended
December 31, 2012. These financial statements are the responsibility of the Company’s management. Our
responsibility is to express an opinion on these financial statements based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in all material respects, the
consolidated financial position of Comstock Resources, Inc. and subsidiaries at December 31, 2011 and
2012, and the consolidated results of their operations and cash flows for each of the three years in the
period ended December 31, 2012, in conformity with accounting principles generally accepted in the
United States.

We also have audited,

in accordance with the standards of the Public Company Accounting
Oversight Board (United States), the effectiveness of Comstock Resources, Inc.’s internal control over
financial reporting as of December 31, 2012, based on criteria established in Internal Control-Integrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our
report dated February 28, 2013 expressed an adverse opinion thereon.

COMSTOCK RESOURCES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) Summary of Significant Accounting Policies

Accounting policies used by Comstock Resources, Inc. reflect oil and natural gas industry practices

and conform to accounting principles generally accepted in the United States of America.

Basis of Presentation and Principles of Consolidation

Comstock Resources, Inc.

is engaged in oil and natural gas exploration, development and
production, and the acquisition of producing oil and natural gas properties. The Company’s operations are
primarily focused in Texas and Louisiana. The consolidated financial statements include the accounts of
Comstock Resources, Inc. and its wholly owned or controlled subsidiaries (collectively, “Comstock” or
the “Company”). During 2011 and 2012 the consolidated financial statements also include the accounts of
a variable interest entity where the Company was the primary beneficiary of the arrangements. All
significant intercompany accounts and transactions have been eliminated in consolidation. The Company
accounts for its undivided interest in oil and gas properties using the proportionate consolidation method,
whereby its share of assets, liabilities, revenues and expenses are included in its financial statements.

Reclassifications

Certain reclassifications have been made to prior periods’ financial statements to conform to the

current presentation.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with generally accepted accounting principles
requires management to make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the
reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from
those estimates. Changes in the future estimated oil and natural gas reserves or the estimated future cash
flows attributable to the reserves that are utilized for impairment analysis could have a significant impact
on the future results of operations.

Concentration of Credit Risk and Accounts Receivable

Financial instruments that potentially subject the Company to a concentration of credit risk consist
principally of cash and cash equivalents, accounts receivable and derivative financial instruments. The
Company places its cash with high credit quality financial institutions and its derivative financial
instruments with financial institutions and other firms that management believes have high credit ratings.
Substantially all of the Company’s accounts receivable are due from either purchasers of oil and gas or
participants in oil and gas wells for which the Company serves as the operator. Generally, operators of oil
and gas wells have the right to offset future revenues against unpaid charges related to operated wells. Oil
and gas sales are generally unsecured. The Company’s policy is to assess the collectability of its
receivables based upon their age, the credit quality of the purchaser or participant and the potential for
revenue offset. The Company has not had any significant credit losses in the past and believes its
accounts receivable are fully collectible. Accordingly, no allowance for doubtful accounts has been
provided.

Marketable Securities

As of December 31, 2011 and 2012,

the Company owned 1,806,000 and 600,000 shares,
respectively, of Stone Energy Corporation common stock which was reflected in the consolidated balance
sheets as marketable securities. As of December 31, 2011 and 2012, the cost basis of the marketable

F-8

COMSTOCK RESOURCES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

securities was $16.6 million and $5.5 million, respectively. As of December 31, 2011 and 2012, the
estimated fair value of the marketable securities was $47.6 million and $12.3 million, respectively, after
recognizing unrealized gain after income taxes of $20.2 million and $4.4 million, respectively. The
Company does not exert influence over the operating and financial policies of Stone, and has classified its
investment in these shares as an available-for-sale security in the consolidated balance sheets. Available-
for-sale securities are accounted for at fair value, with any unrealized gains and unrealized losses not
determined to be other than temporary reported in the consolidated balance sheet within accumulated
other comprehensive income as a separate component of stockholders’ equity. The Company utilizes the
specific identification method to determine the cost of any securities sold. During 2010, 2011 and 2012
the Company sold 1,520,000, 1,991,000 and 1,206,000 shares of Stone common stock for proceeds of
$30.5 million, $53.4 million and $37.7 million, respectively. Comstock realized gains before income
taxes of $16.5 million, $35.1 million and $26.6 million on these sales during 2010, 2011 and 2012,
respectively. The Company reviews its available-for-sale securities to determine whether a decline in fair
value below the respective cost basis is other than temporary. Unrealized losses are charged against net
earnings when a decline in fair value is determined to be other than temporary.

Other Current Assets

Other current assets at December 31, 2011 and 2012 consist of the following:

Fair Value Measurements

The Company holds or has held certain items that are required to be measured at fair value. These
include cash equivalents held in bank accounts, marketable securities and derivative financial instruments
in the form of oil price swap agreements. Fair value is defined as the price that would be received to sell
an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the
asset or liability in an orderly transaction between market participants on the measurement date. A three-
level hierarchy is followed for disclosure to show the extent and level of judgment used to estimate fair
value measurements:

Level 1 – Inputs used to measure fair value are unadjusted quoted prices that are available in

active markets for the identical assets or liabilities as of the reporting date.

Level 2 – Inputs used to measure fair value, other than quoted prices included in Level 1, are
either directly or indirectly observable as of the reporting date through correlation with market data,

F-9

COMSTOCK RESOURCES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

including quoted prices for similar assets and liabilities in active markets and quoted prices in
markets that are not active. Level 2 also includes assets and liabilities that are valued using models
or other pricing methodologies that do not require significant judgment since the input assumptions
used in the models, such as interest rates and volatility factors, are corroborated by readily
observable data from actively quoted markets for substantially the full
term of the financial
instrument.

Level 3 – Inputs used to measure fair value are unobservable inputs that are supported by little
or no market activity and reflect the use of significant management judgment. These values are
generally determined using pricing models for which the assumptions utilize management’s
estimates of market participant assumptions.

The Company’s cash and marketable securities valuation are based on Level 1 measurements. The
Company’s oil and natural gas price swap agreements were not traded on a public exchange, and their
value was determined utilizing a discounted cash flow model based on inputs that are readily available in
public markets and, accordingly, the valuation of these swap agreements was categorized as a Level 2
measurement.

Property and Equipment

The Company follows the successful efforts method of accounting for its oil and gas properties.
Acquisition costs for proved oil and gas properties, costs of drilling and equipping productive wells, and
costs of unsuccessful development wells are capitalized and amortized on an equivalent unit-of-
production basis over the life of the remaining related oil and gas reserves. Equivalent units are
determined by converting oil to natural gas at the ratio of one barrel of oil for six thousand cubic feet of
natural gas. This conversion ratio is not based on the price of oil or natural gas, and there may be a
significant difference in price between an equivalent volume of oil versus natural gas. Cost centers for
amortization purposes are determined on a field area basis. Costs incurred to acquire oil and gas leasehold
are capitalized. The estimated future costs of dismantlement, restoration, plugging and abandonment of
oil and gas properties and related facilities disposal are capitalized when asset retirement obligations are
incurred and amortized as part of depreciation, depletion and amortization expense. The costs of
unproved properties which are determined to be productive are transferred to proved oil and gas
properties and amortized on an equivalent unit-of-production basis. Exploratory expenses, including
geological and geophysical expenses and delay rentals for unevaluated oil and gas properties, are charged
to expense as incurred. Unproved oil and gas properties are periodically assessed for impairment on a
property by property basis, and any impairment in value is charged to exploration expense. During 2011
and 2012, impairment charges of $9.8 million and $61.3 million, respectively, were recognized in
exploration expense related to certain leases that the Company no longer expects to drill on. Exploratory
drilling costs are initially capitalized as unproved property but charged to expense if and when the well is
determined not to have found commercial quantities of proved oil and gas reserves. Exploratory drilling
costs are evaluated within a one-year period after the completion of drilling.

F-11

COMSTOCK RESOURCES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The Company periodically assesses the need for an impairment of the costs capitalized for its oil and
gas properties on a property or cost center basis. If impairment is indicated based on undiscounted
expected future cash flows attributable to the property, then a provision for impairment is recognized to
the extent that net capitalized costs exceed the estimated fair value of the property. The fair value is based
upon estimated discounted future cash flows which are derived from Level 3 inputs. Expected future cash
flows are determined using estimated future prices based on market based forward prices applied to
projected future production volumes. Costs are also projected to escalate at a rate that is based upon the
Company’s historical experience. The projected production volumes are based on the property’s proved
and risk adjusted probable oil and natural gas reserve estimates at the end of the period. The oil and
natural gas prices used for determining asset impairments will generally differ from those used in the
standardized measure of discounted future net cash flows because the standardized measure requires the
use of an average price based on the first day of each month of the preceding year and is limited to proved
reserves. The Company recognized impairment charges related to its oil and gas properties of $0.2
million, $60.8 million and $25.4 million in 2010, 2011, and 2012, respectively.

Other property and equipment consists primarily of gas gathering systems, computer equipment,
furniture and fixtures and an airplane which are depreciated over estimated useful lives ranging from
three to 31 1⁄2 years on a straight-line basis.

Other Assets

Other assets primarily consist of deferred costs associated with issuance of the Company’s senior
notes and bank credit facility. These costs are amortized over the life of the senior notes and the life of the
bank credit facility on a straight-line basis which approximates the amortization that would be calculated
using an effective interest rate method.

Reserve for Future Abandonment Costs

The Company’s asset retirement obligations relate to future plugging and abandonment costs of its
oil and gas properties and related facilities disposal. The Company records a liability in the period in
which an asset retirement obligation is incurred, in an amount equal to the discounted estimated fair value
of the obligation that is capitalized. Thereafter, this liability is accreted up to the final retirement cost.
Accretion of the discount
is included as part of depreciation, depletion and amortization in the
accompanying consolidated financial statements.

Stock-based Compensation

The Company has stock-based employee compensation plans under which stock awards, comprised
of restricted stock, stock options and performance share units are issued to employees and non-employee
directors. The Company follows the fair value based method in accounting for equity-based
compensation. Under the fair value based method, compensation cost is measured at the grant date based
on the fair value of the award and is recognized on a straight-line basis over the award vesting period.
Excess tax benefits on stock-based compensation are recognized as an adjustment to additional paid-in
capital and as a part of cash flows from financing activities.

Segment Reporting

The Company presently operates in one business segment, the exploration and production of oil and

natural gas.

Derivative Instruments and Hedging Activities

The Company accounts for derivative instruments (including certain derivative instruments
embedded in other contracts) as either an asset or liability measured at its fair value. Changes in the fair
value of derivatives are recognized currently in earnings unless specific hedge accounting criteria are met.
The Company estimates fair value based on a discounted cash flow model and quotes obtained from the
counterparties to the derivative contract. The fair value of derivative contracts that expire in less than one
year are recognized as current assets or liabilities. Those that expire in more than one year are recognized
as long-term assets or liabilities. Derivative financial instruments that are not accounted for as hedges are
adjusted to fair value through income. If the derivative is designated as a cash flow hedge, changes in fair
value are recognized in other comprehensive income until the hedged item is recognized in earnings.

Major Purchasers

In 2012 the Company had two purchasers of its oil and natural gas production that accounted for
42% and 27%, respectively, of total oil and gas sales. In 2011 the Company had two purchasers of its oil
and natural gas production that accounted for 49% and 14%, respectively, of total oil and gas sales. In
2010 the Company had one purchaser of its oil and natural gas production that accounted for 39% of total
oil and gas sales. The loss of any of these customers would not have a material adverse effect on the
Company as there is an available market for its oil and natural gas production from other purchasers.

F-13

COMSTOCK RESOURCES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Revenue Recognition and Gas Balancing

Comstock utilizes the sales method of accounting for oil and natural gas revenues whereby revenues
are recognized at the time of delivery based on the amount of oil or natural gas sold to purchasers.
Revenue is typically recorded in the month of production based on an estimate of the Company’s share of
volumes produced and prices realized. Revisions to such estimates are recorded as actual results are
known. The amount of oil or natural gas sold may differ from the amount to which the Company is
entitled based on its revenue interests in the properties. The Company did not have any significant
imbalance positions at December 31, 2011 or 2012. Sales of oil and natural gas generally occur at the
wellhead. When sales of oil and gas occur at locations other than the wellhead, the Company accounts for
costs incurred to transport the production to the delivery point as operating expenses.

General and Administrative Expenses

General and administrative expenses are reported net of reimbursements of overhead costs that are
received from working interest owners of the oil and gas properties operated by the Company of $10.6
million, $10.5 million and $11.5 million in 2010, 2011 and 2012, respectively.

Income Taxes

The Company accounts for income taxes using the asset and liability method, whereby deferred tax
assets and liabilities are recognized for the future tax consequences attributable to differences between the
financial statement carrying amounts of assets and liabilities and their respective tax basis, as well as the
future tax consequences attributable to the future utilization of existing tax net operating loss and other
types of carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected
to apply to taxable income in the years in which those temporary differences and carryforwards are
expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax
rates is recognized in income in the period that the change in rate is enacted.

Earnings Per Share

Basic earnings per share is determined without the effect of any outstanding potentially dilutive
stock options and diluted earnings per share is determined with the effect of outstanding stock options
that are potentially dilutive. Unvested share-based payment awards containing nonforfeitable rights to
dividends are considered to be participatory securities and included in the computation of basic and
diluted earnings per share pursuant to the two-class method. Performance share units (“PSUs”) represent
the right to receive a number of shares of the Company’s common stock that may range from zero to up
to three times the number of PSUs granted on the award date based on the achievement of certain
performance measures during a performance period. The number of potentially dilutive shares related to
PSUs is based on the number of shares, if any, which would be issuable at the end of the respective
period, assuming that date was the end of the contingency period. The treasury stock method is used to
measure the dilutive effect of PSUs.

(2) Acquisitions and Dispositions of Oil and Gas Properties

On December 29, 2011, the Company completed an acquisition, from an unrelated party, of oil and
gas properties in the Delaware Basin located in Reeves County in West Texas (the “Delaware Basin
Acquisition”). Total cash consideration paid of $337.9 million was funded with borrowings under the
Company’s bank credit facility. The Company acquired proved oil and gas reserves of 25.2 million
barrels of oil equivalent and leases covering 43,591 net acres. The effective date of the acquisition was
November 1, 2011. Concurrent with the Delaware Basin Acquisition, Comstock entered into a transaction
structured as a reverse like-kind exchange in accordance with Section 1031 of the Internal Revenue Code.
In connection with this reverse like-kind exchange, Comstock assigned the right to acquire ownership in
the oil and gas properties that were acquired to a variable interest entity formed by an exchange
accommodation titleholder. Comstock operated these properties pursuant to lease and management
agreements with that entity, and had a call option which allowed the Company to terminate the exchange
transaction at any time up and until the expiration date of the exchange. The exchange transaction was
completed in May 2012 and the variable interest entity was then merged into a wholly owned subsidiary
of the Company. Because the Company was the primary beneficiary of these arrangements, the properties
acquired are included in its consolidated balance sheet as of December 31, 2011, and all revenues earned
and expenses incurred related to the properties were included in the Company’s consolidated results of
operations during the term of the agreements.

The purchase price allocation, including final post-closing adjustments finalized during 2012, was as

On December 30, 2011, the Company acquired oil and gas properties in North Louisiana from a
third party for $27.1 million. This acquisition included proved oil and gas reserves of 13 billion cubic feet
of natural gas equivalent and leases covering 3,500 net acres.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Comstock considered the property acquisitions as business combinations and estimated the fair value
of the properties as of the acquisition date. To estimate the fair value of the properties, the Company used
a net asset value approach. The Company utilized a discounted cash flow model that took into account the
following inputs to arrive at estimates of future net cash flows:

• Estimated ultimate recovery of oil and natural gas;
• Estimated future commodity prices based on NYMEX oil and natural gas futures prices adjusted

for estimated location and quality differentials as well as related transportation costs;

• Estimated future production rates; and
• Estimated timing and amounts of future operating and development costs.

To estimate the fair value of proved properties, the Company discounted the future net cash flows
using a market-based rate that the Company determined appropriate at the acquisition date for the various
proved reserve categories. Due to the unobservable nature of the inputs, the fair values of the proved and
unproved oil and gas properties are considered Level 3 fair value measurements.

During 2012, the Company completed the sale of certain oil and gas properties located in Tyler and
Polk counties in South Texas and Lincoln Parish in North Louisiana. The Company received aggregate
net proceeds of $119.8 million and recognized a total gain of $26.0 million from these transactions. Also
during 2012, the Company completed the sale of certain non-operated oil and gas properties acquired as
part of the Delaware Basin Acquisition and received net proceeds of $24.8 million. The Company
accounted for the disposal of these properties as a retirement since they represented a small portion of the
assets within one of its major oil and gas properties.

On July 30, 2012, the Company entered into a participation agreement with Kohlberg Kravis
Roberts & Co L.P. (together with its affiliates, “KKR”) providing for the participation of KKR in
Comstock’s future development of its Eagle Ford shale properties in South Texas. Under the terms of the
participation agreement, KKR has the right to participate for one-third of Comstock’s working interest in
wells drilled on the Company’s 28,160 net acres in exchange for KKR paying $25,000 per acre for the net
acreage being acquired and one-third of the wells costs. Each well that KKR participates in is intended to
earn KKR approximately one-third of the Company’s working interest in approximately 80 acres. The
agreement applies to wells spud by the Company on or subsequent to March 31, 2012. The Company
retains all of its interest in wells that were spud prior to March 31, 2012. Subject to certain conditions,
KKR is obligated to acquire acreage for the first 100 wells drilled on the Company’s Eagle Ford Shale
acreage after July 30, 2012 and can continue to participate in additional wells drilled on the acreage under
the same terms. Comstock received $23.8 million from KKR to fund its participation in drilling activity
before the closing on July 30, 2012. During 2012 the Company also received $8.7 million for acreage and
facility costs for new wells drilled subsequent to the closing. The Company accounted for the receipt of
these funds as a retirement since they represented a small portion of the costs within one of its major oil
and gas properties. Formation costs of $1.7 million incurred in connection with this joint venture are
reflected as a reduction to the realized gain on sale of oil and gas properties in the consolidated financial
statements.

Comstock has a $850.0 million bank credit facility with Bank of Montreal, as the administrative
agent. The credit facility is a five year revolving credit commitment that matures on November 30, 2015.
Indebtedness under the credit facility is secured by substantially all of Comstock’s assets and is
guaranteed by all of its wholly owned subsidiaries. The credit facility is subject to borrowing base
availability, which is redetermined semiannually based on the banks’ estimates of the Company’s future
net cash flows of oil and natural gas properties. The borrowing base may be affected by the performance
of Comstock’s properties and changes in oil and natural gas prices. The determination of the borrowing
base is at the sole discretion of the administrative agent and the bank group. As of December 31, 2012,
the borrowing base was $570.0 million, $130.0 million of which was available. Borrowings under the
credit facility bear interest, based on the utilization of the borrowing base, at Comstock’s option at either
(1) LIBOR plus 1.75% to 2.75% or (2) the base rate (which is the higher of the administrative agent’s
prime rate, the federal funds rate plus 0.5% or 30 day LIBOR plus 1.0%) plus 0.75% to 1.75%. A
commitment fee of 0.5% is payable annually on the unused borrowing base. The credit facility contains
covenants that, among other things, restrict the payment of cash dividends in excess of $50.0 million,
limit the amount of consolidated debt that Comstock may incur and limit the Company’s ability to make
certain loans and investments. The only financial covenants are the maintenance of a ratio of current
assets, including availability under the bank credit facility, to current liabilities and maintenance of a
leverage ratio. The Company was in compliance with these covenants as of December 31, 2012.

On June 5, 2012 the Company issued $300.0 million of senior notes (the “2020 Notes”) pursuant to
an underwritten public offering. The 2020 Notes are due on June 15, 2020 and bears interest at 9 1⁄2%,
which is payable semi-annually on each June 15 and December 15. Proceeds from the issuance of the
2020 Notes were used to pay down outstanding borrowings under the Company’s bank credit facility. On
March 14, 2011, Comstock issued $300.0 million of senior notes (the “2019 Notes”) pursuant to an
underwritten public offering. The 2019 Notes are due on April 1, 2019 and bear interest at 7 3⁄4%, which is
payable semiannually on each April 1 and October 1. Comstock also has $300.0 million of 8 3⁄8% senior
notes outstanding which mature on October 15, 2017 (the “2017 Notes”). Interest on the 2017 Notes is
payable semiannually on each April 15 and October 15. The 2017, 2019 and 2020 Notes are unsecured
obligations of Comstock and are guaranteed by all of Comstock’s material subsidiaries. Such subsidiary
guarantors are 100% owned and all of the guarantees are full and unconditional and joint and several
obligations. As of December 31, 2012, Comstock had no material assets or operations which are
independent of its subsidiaries. There are no restrictions on the ability of Comstock to obtain funds from
its subsidiaries through dividends or loans.

On January 1, 2011, Comstock had $172.0 million in principal amount of 6 7⁄8% senior notes
outstanding due in 2012 (the “2012 Notes”). Comstock redeemed all of the 2012 Notes in March 2011 for
$172.4 million. The early extinguishment of the 2012 Notes resulted in a loss of $1.1 million which is
included in interest expense in the consolidated financial statements. This loss is comprised of the
premium paid for the redemption of the 2012 Notes, the costs incurred related to the tender offer, and the
write-off of unamortized debt issuance costs related to the 2012 Notes.

restricted stock of $19.1 million as of December 31, 2012 is expected to be recognized over a period of
2.3 years. The fair value of restricted stock which vested in 2010, 2011 and 2012 was $15.1 million, $9.3
million and $6.7 million, respectively.

Performance Share Units

The Company issues PSUs as part of its long-term equity incentive compensation. PSU awards can
result in the issuance of common stock to the holder if certain performance criteria is met during a
performance period. The performance periods consist of one year, two years and three years, respectively.
The performance criteria for the PSUs are based on the Company’s annualized total stockholder return
(“TSR”) for the performance period as compared with the TSR of certain peer companies for the
performance period. The costs associated with PSUs are recognized as general and administrative
expense over the performance periods of the awards.

The fair value of PSUs was measured at the grant date using a stochastic process method utilizing
the Geometric Brownian Motion Model (“GBM Model”). A stochastic process is a mathematically
defined equation that can create a series of outcomes over time. These outcomes are not deterministic in
nature, which means that by iterating the equations multiple times, different results will be obtained for
those iterations. In the case of the Company’s PSUs, the Company cannot predict with certainty the path
its stock price or the stock prices of its peers will take over the future performance periods. By using a
stochastic simulation, the Company can create multiple prospective total return pathways, statistically
analyze these simulations, and ultimately make inferences to the most likely path the total return will
take. As such, because future stock returns are stochastic, or probabilistic with some direction in nature,
the stochastic method, specifically the GBM Model, is deemed an appropriate method by which to

F-23

COMSTOCK RESOURCES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

determine the fair value of the PSUs. Significant assumptions used in this simulation include the
Company’s expected volatility and a risk-free interest rate based on U.S. Treasury yield curve rates with
maturities consistent with the vesting periods, as well as the volatilities for each of the Company’s peers.
For the PSUs granted in 2012, the valuation inputs included a risk-free interest rate of 0.4% and a range
of volatilities of 29% to 70%.

The Company granted 254,133 PSUs in 2012, all of which were outstanding at December 31, 2012,
with a grant date fair value of $5.4 million, or $21.14 per unit. The number of awards assumes a one
multiplier. The final number of shares of common stock issued may vary depending upon the
performance multiplier, and can result in the issuance of zero to 688,545 shares of common stock based
on the achieved performance ranges from zero to three.

Total compensation expense for PSUs was $0.2 million for the year ended December 31, 2012. As of
December 31, 2012, there was $5.2 million of total unrecognized expense related to PSUs, which is being
amortized through December 2015.

(8) Retirement Plan

The Company has a 401(k) profit sharing plan which covers all of its employees. At its discretion,
Comstock may match a certain percentage of the employees’ contributions to the plan. Matching
contributions to the plan were $341,000, $323,000 and $365,000 for the years ended December 31, 2010,
2011 and 2012, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

valuation allowance of $23.0 million, with a tax effect of $8.0 million, has been established for the
estimated U.S. federal net operating loss carryforwards that will not be utilized. Realization of the
remaining U.S. federal net operating loss carryforwards requires Comstock to generate taxable income
within the carryforward period. A valuation allowance of $288.0 million, with a tax effect of $15.0
million, has been established against the Louisiana state net operating loss carryforwards due to the
uncertainty of generating taxable income in the state of Louisiana prior to the expiration of the
carryforward period.

The Company’s federal income tax returns for the years subsequent to December 31, 2007 remain
subject to examination. The Company’s income tax returns in major state income tax jurisdictions remain
subject to examination for various periods subsequent to December 31, 2007. State tax returns in two
state jurisdictions are currently under review. The Company currently believes that resolution of these
matters will not have a material impact on its financial statements. The Company currently believes that
its significant filing positions are highly certain and that all of its other significant income tax filing
positions and deductions would be sustained upon audit or the final resolution would not have a material
effect on the consolidated financial statements. Therefore,
the Company has not established any
significant reserves for uncertain tax positions. Interest and penalties resulting from audits by tax
authorities have been immaterial and are included in the provision for income taxes in the consolidated
statements of operations.

(10) Derivative Financial Instruments and Hedging Activities

Comstock periodically uses swaps, floors and collars to hedge oil and natural gas prices and interest
rates. Swaps are settled monthly based on differences between the prices specified in the instruments and
the settlement prices of futures contracts. Generally, when the applicable settlement price is less than the
price specified in the contract, Comstock receives a settlement from the counterparty based on the
difference multiplied by the volume or amounts hedged. Similarly, when the applicable settlement price
exceeds the price specified in the contract, Comstock pays the counterparty based on the difference.
Comstock generally receives a settlement from the counterparty for floors when the applicable settlement
price is less than the price specified in the contract, which is based on the difference multiplied by the
volumes hedged. For collars, generally Comstock receives a settlement from the counterparty when the
settlement price is below the floor and pays a settlement to the counterparty when the settlement price
exceeds the cap. No settlement occurs when the settlement price falls between the floor and cap.

During 2012, the Company hedged 1,710,000 barrels of its oil production at an average NYMEX
West Texas Intermediate (“WTI”) oil price of $99.46 per barrel. As of December 31, 2012, the Company
had the following outstanding commodity derivatives:

The Company recognizes the realized gains and losses, and the unrealized gains and losses due to
the change in the fair value of its derivative financial instruments, as separate components of other
income (expenses). The Company had realized gains of $9.8 million on its oil swaps that settled during

2012. The estimated fair value of the Company’s derivative financial instruments, which equals their
carrying value, was an asset of $11.7 million as of December 31, 2012, which is reflected as a current
asset based on estimated settlement dates.

The Company is restating its financial statements for each of the fiscal quarters ended March 31,
2012, June 30, 2012, and September 30, 2012 with respect to the accounting and disclosures for certain
derivative financial transactions under Accounting Standards Codification Topic 815, Derivatives and
Hedging (“ASC 815”). The Company determined that the formal documentation it had prepared to
support its initial hedge designations for effectiveness in connection with the Company’s oil hedging
program was not compliant with the technical documentation requirements to qualify for cash flow hedge
accounting treatment in accordance with ASC 815, and as a result, the Company was not permitted to
utilize hedge accounting treatment in the preparation of its financial statements. The restatements
eliminate hedge accounting treatment which had been applied in 2012 and reflect other immaterial
adjustments to oil and gas sales.

Under ASC 815, the fair value of hedge contracts is recognized in the Company’s consolidated
balance sheet as an asset or liability, as the case may be, and the amounts received or paid under the
hedge contracts are reflected in earnings during the period in which the underlying production occurs. If
the hedge contracts qualify for cash flow hedge accounting treatment, the fair value of the hedge contract
is recorded in “accumulated other comprehensive income”, and changes in the fair value do not affect net
income in the period. If the hedge contract does not qualify for hedge accounting treatment, the change in
the fair value of the hedge contract is reflected in earnings during the period as unrealized gain or loss
from derivatives. Under the cash flow hedge accounting treatment used by the Company, the fair value of
the hedge contracts were recognized in the consolidated balance sheet with the resulting unrealized gain
or loss recorded initially in “accumulated other comprehensive income” and later reclassified through
earnings when the hedged production impacted earnings. As a result of the determination that the
designation documentation failed to meet
the requirements necessary to utilize cash flow hedge
accounting treatment,
the unrealized gain or loss should have been recorded in the consolidated
statements of operations as a component of earnings. The Company has also been recognizing realized
gains and losses from its derivative financial instruments in oil and gas sales, and is reclassifying these
amounts as a separate component of non-operating income and expense.

During 2012, the Company’s estimated quantities of proved undeveloped natural gas reserves
decreased by 460 Bcf from total proved undeveloped reserves as of December 31, 2011 due to downward
revisions related to the lower natural gas price that was used to determine estimated reserve quantities at
December 31, 2012. Substantially all of the Company’s proved undeveloped natural gas reserves related
to undrilled natural gas wells at December 31, 2011 were not economic at the lower natural gas price at
December 31, 2012. The decrease in proved undeveloped natural gas reserves in 2012 resulted in an
increase to the Company’s per unit amortization rate for its proved oil and gas properties and,
accordingly, increased depletion, depreciation and amortization expense during 2012 as compared to
previous periods.

The proved oil and gas reserves utilized in the preparation of the financial statements were estimated
by Lee Keeling and Associates,
independent petroleum consultants, in accordance with guidelines
established by the Securities and Exchange Commission and the Financial Accounting Standards Board,
which require that reserve reports be prepared under existing economic and operating conditions with no
provision for price and cost escalation except by contractual agreement. All of the Company’s reserves
are located onshore in the continental United States of America.

The standardized measure of discounted future net cash flows at the end of 2011 and 2012 was
determined based on the simple average of the first of month market prices for oil and natural gas for each
year. Prices were $92.93 per barrel of oil and $4.18 per Mcf of natural gas for 2011 and $94.61 per barrel
of oil and $2.84 per Mcf of natural gas for 2012. Prices used in determining quantities of oil and natural
gas reserves and future cash inflows from oil and natural gas reserves represent prices received at the
Company’s sales point. These prices have been adjusted from posted or index prices for both location and
quality differences. Future development and production costs are computed by estimating the
expenditures to be incurred in developing and producing proved oil and gas reserves at the end of the
year, based on year end costs and assuming continuation of existing economic conditions. Future income
tax expenses are computed by applying the appropriate statutory tax rates to the future pre-tax net cash
flows relating to proved reserves, net of the tax basis of the properties involved. The future income tax
expenses give effect to permanent differences and tax credits, but do not reflect the impact of future
operations.

The following table sets forth the changes in the standardized measure of discounted future net cash

flows relating to proved reserves for the years ended December 31, 2010, 2011 and 2012:
